Ddr2nite: /* November 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-23T01:21:27Z

Ddr2nite: Sunstreaker bundles

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

The various "Sunstreaker Bundle" listed above allowed players to use existing Gems from their account (as opposed to real world currency) to purchase the items in the bundle.

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-23T00:44:17Z

Ddr2nite: /* February 2018 ~ Current */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-17T17:59:53Z

Ddr2nite: /* February 2018 ~ Current */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-16T01:53:12Z

Ddr2nite: /* December 2016 ~ March 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Ddr2nite: proper formatting

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Ddr2nite: /* April 2017 ~ June 2017 */ better alignment of last row

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===

[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:55:59Z

Ddr2nite: /* February 2018 ~ Current */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:52:24Z

Ddr2nite: /* February 2018 ~ Current */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

'''''Angry Birds Transformers''''' is a mobile app for both iPhone and Android platforms developed and published by [[Rovio]]. It is a themed version of the developer's mega-popular mobile game ''[[Wikipedia:Angry Birds|Angry Birds]]''.

As of December 2017, it is still live and still updating with new competitions and characters.

==Synopsis==
The [[AllSpark#Angry Birds Transformers comic|EggSpark]] has landed on [[Piggy Island]], transforming its dueling inhabitants and giving them bodies and powers based on the Transformers: the birds of the [[Flock]] become [[Autobird]]s and the [[Bad Piggies]] the [[Deceptihog]]s. The two sides briefly continue their struggle with these new powers until they are both threatened by another transformed group, the [[Eggbot (AB)|Eggbot]]s, who seek to transform all of Piggy Island into metal, backed by countless robotized [[Minion Pig]]s.

Most of the Autobirds and all of the Deceptihogs are captured leaving only [[Red (AB)|Red]] (who has the powers of [[Optimus Prime (disambiguation)|Optimus Prime]]) free. The leader of the Flock (you know him well) heads out to free the Autobirds ''and'' Deceptihogs, for only by joining forces can they restore Piggy Island to normal!

==Gameplay==
The game is a deviation from the normal ''Angry Birds'' formula, but the core goal, toppling block towers to pop the Bad Piggies on them, is the same.

Once you select an available stage from the map of Piggie Island, your character runs along the foreground at a set speed, as block towers scroll by in the background. By tapping the screen, your character takes aim and fires their weapon. You can also hold-and-drag to fire in a spread (if the character's weapon isn't a single-shot blast), or press the "Auto" button to let the computer do the targeting for you (though it isn't very efficient). The trick is to quickly determine which blocks in the structure are best to destroy/shove to cause a domino effect, toppling them and popping the Piggies by dropping blocks on them or making them fall far enough. (Remember, weaker blocks are not always the best target!) You can also attack the Piggies directly; in fact, some characters specialize in this more direct approach!

Block types include:
:*'''Ice Blocks''': Very weak, easily shattered (1 Coin)
:*'''Wood Blocks''': Fairly sturdy but not hard to break (2 Coins)
:*'''Stone Blocks''': Very durable, better for pushing than breaking (3 Coins)
:*'''TNT Blocks''': Easily-broken red crates that explode with a considerable radius, sending blocks flying
:*'''Coin Blocks''': Golden blocks that spit out Coins with every hit. Pretty dang sturdy, but if you destroy them, you earn a lot of Coins (50~250 Coins).

Each stage is also littered with cyberformed scenery with blinky lights that can be blasted to revert it to normal. Doing so sends an [[Energon cube]] hurtling towards the character. If the character is accompanied by an [[Energonicon]], the cube is used to fuel its special power, activated by tapping the icon. If not (mostly during Challenge Events), then the character's health will go up about half a heart, only if the character is an Energon variant. A full Energonicon cannot make use of extra cubes, so timely tapping to spend the energy before obtaining more is key. As your characters level up, they can store more Energon cubes, up to three, which generally extend the duration of the Energonicon's effects.

Most areas also have random destructible elements that can be blasted. The more destruction you cause, the more Coins you get to buy upgrades and explore new areas. Each level has a set length; you do not have to pop every Piggie to pass, merely survive to the end.

"Survive"? Yeah. Some Piggies are weaponized and will begin to attack shortly after appearing on-screen, even before you can retaliate. Thus, popping these Piggies (or at least upending them to throw off their aim) quickly becomes essential. You can also try to escape attacks and falling Monoliths by transforming to vehicle mode. This speeds you along a bit, but removes your ability to attack or call in partners, plus you can only maintain vehicle mode for a limited time. Attacking automatically transforms you back to robot mode. There are other obstacles that can decrease a character's health bar; lose all your life and the character is picked up by [[Astrotrain (G1)|Astrotrain]]; you can then spend some [[Gem]]s to immediately put them back into the fight, or let the timer run out and quit the level. If you quit, you will not earn Piggie points for the level, you do keep any Coins you collected. Health does not restore between levels, so if a character is low you must spend Coins to repair them. This takes them out of the game for a while, in real-time, even when the game is off. You can then repair them instantly by spending Gems, or you can skip all that and immediately restore them to full health instantly by watching an ad (up to 30 seconds long) or scanning their transformable figure (if they have one) with a [[Telepod]].

New stages are unlocked by leveling up your characters, increasing your Rank one point with every level-up. Every 5 or 10 Rank settings lets you clear the clouds away from a new area of Piggy Island. Some areas can only be unlocked by using Plasma. Plasma can be unlocked by Challenge Events, Daily Quests, Daily Rewards, and Crates.

Cleared stages will slowly earn Coins over real-time. Tapping on the Coins on the map adds them to your bank. After a set point they will not accrue anymore: this threshold is about four hours of real time, the maximum amount hinging on how many character Squads you've completed. There are also randomly spawning treasure chests on the map, tap them to earn various amounts of Gems. However, roaming Eggbots will re-cyberform cleared stages, which removes their Coin bonuses. You can see which stages they are working on, how long the cyberforming process will take, and even interrupt their work (at the cost of Gems), giving you the chance to pelt an Eggbot in-level for extra Coins. Cyberforming too goes on in real-time. Once a stage is re-cyberformed, it can be played again. Note that merely peeking at an in-development will not automatically charge you Gems; you still have a choice to intercept or not.

===Character Choices===
Every stage has a pre-set character you control, based on who you've rescued so far. Every character has a different style of attack, movement speed, and armor rating. Working out the strengths and weaknesses of each character is key to high scores, and in some cases simple survival.

New characters can be added to your roster in two different ways. In-game, most characters are held captive in a block of ice on the map, one per area, and you must "spend" a specific number of popped Piggies to break them out. You then have to play a short level with that character, and if they make it to the end, they're yours to keep. If not, they are re-frozen, but thankfully you can try again without having to spend all those hard-earned Piggy points again. There are many other characters who can be unlocked via Space Bridge Missions (see below) or Challenge Events (also see below).

Out-of-game, this is where you can spend actual-factual money, on the [[Angry Birds Transformers (toyline)|tie-in toys]]. By placing one of the figures on a [[Telepod]] and placing ''that'' on your device's camera lens, the game reads the code on the figure and inserts it into the game for a limited amount of time (currently 24 hours). While the characters unlocked this way are only available temporarily until unlocked via Piggie points, there is no limit on how often you can scan the figure, plus any upgrade progress is saved. You can also use this method to power-up already-unlocked characters before a stage or speed up their repairs without spending Gems; again there is no limit to the number of times you can scan (but the effects will not stack).

;Improving characters
Every character can be upgraded multiple times (nominal maximum level for characters is 15, but they can be upgraded further than that in select Challenge Events) by spending Coins and Materials, which (of course) takes them out of play for a while. Each upgrade is pre-set, increasing attack strength, armor strength, or vehicle mode duration. At certain levels, their Energon capacity is increased, and these levels vary from character to character. You can spend much-rarer Gems to make the upgrade happen instantly; the closer the upgrades are to complete, the fewer Gems you need to spend. Upgrading characters is ''vital'' as the levels get harder and harder, not to mention in the phone version you can only unlock new areas with an overall player level, which is raised by upgrading your characters. This isn't the case in the tablet version where you can spend Gold Coins to unlock new areas. You can only have one character undergoing an upgrade at a time.

Characters can also be upgraded inside Astrotrain by customizing them with Accessories. These extra items cost Gems (or Tokens, see "Challenge Events" below) and not only alter the characters' appearance, but they boost stats, or imbue special abilities to weapons. One Accessory can be placed on a character's head, face, chest, arms and back each. Some Challenge Events have special exclusive Accessories you can't buy with Gems! As most Accessories are character-specific, see each character's page for more detailed information.

;Call-in Buddies
Soon you get the option to have a second character on standby, who you can call in and have the computer control for a brief period. They enter the stage in slow motion with a massive shockwave that does damage to most everything within the blast radius, obliterating Ice Blocks but only damaging tougher targets. These characters will warp out after a few seconds, then you must wait for their meter to re-charge before calling them back in. However, there's a limit to when you are able to call in a partner; once you see [[Astrotrain (G1)#Angry Birds Transformers|Astrotrain]] fly overhead, your partner's no longer available. On the other hand, the stage is close to over! But if your partner is ''already'' out when you hit that checkpoint, then they will stay active until the very end of the level, nice for really piling on the destruction.

You get to see your partner before you start the stage, and if you don't like that character choice, you can change it by spending some Coins. Partners are either randomly generated (which can let you see characters you haven't unlocked yet), or pulled from the character rosters of your friends if you've connected to the game via Facebook or Google+ or iTunes or whatever the social network stuff the kids are into these days is. If you called on them in the level, you can "thank" them afterward. Doing so gives the other player a nominal reward (either a Gem or 25 Coins), while not thanking them simply tells the other player that while you're grateful for the firepower assist, you don't think they deserve any actual compensation. You jerk. However this seems to be only for your friends if you use the social network support. When you don't have friends or don't believe in social media, you get random users to help, and if people use your characters and you're not friends with them via social network you don't get any rewards if they thank you.

{{anchor|Squads}}
;Squads
Completing character Squads is the key to bigger earnings, in many different ways. The more Squads you have filled out, the higher the max number of Coins unoccupied map spaces can accrue. Also, any character from a completed Squad earns a 50% Coins bonus once they finish a level. Luckily, any Squads you complete will ''stay'' checked as complete even if new characters are later added to them, so you don't have to worry about losing bonuses with game updates.

During many Challenge Events (see below), you can earn bonuses to your Event scores by using a character from the suggested Squad. For a while the chosen Squad changed every four hours with (mostly) randomized percentages, but currently stays set at a single squad for the duration of the Event, with a x3 score multiplier ''if'' the character has been "Promoted".

===Materials===
[[File:ABTF-screen MaterialSilo.jpg|right|thumb|300px|]]
Materials are special items earned by successfully completing stages, Missions, and Daily Quests, stored in the Silo. These are used to create Energonicons (and other prizes) at [[Professor Pig]]'s lab, and to upgrade your characters.

The amount of Materials you can store is dictated by the level of the Silo. The Silo can be upgraded using Coins and Materials, which not only lets you store larger numbers and higher levels of Materials, but increases the number and rarity of Materials rewarded upon stage completion. Any Materials won that exceed the Silo's capacity are converted to Coins. The Silo's maximum level was 15, but a fall 2017 update increased the storage capacity to 25.

===Space Bridge Missions===
In addition to the stages, there are [[space bridge|Space Bridge]] Missions that your freed characters can complete in order to earn Materials, Coins, Gems, or even new characters (Arcee, Airachnid, Prowl, and Bluestreak). There are three Space Bridges difficulties —Easy, Medium, and Hard— progressively unlocked by clearing more of the map of clouds. Each Space Bridge also has three Missions to choose from when open, with three different time requirements: the longer the Mission, the better the potential prizes.

Missions are "played" by selecting up to three characters from your available roster to participate. The Easy Bridge lets you send two characters for free, the other two only one, and sending any more requires Gem spending. Easy And Medium cost 100 Gems per extra character, and Hard 200, and given you ''might'' get back a grand total of 20 Gems even at the highest prize levels that is compltely not worth it. Characters who are taking part in Missions are basically gone for the duration, unable to be played in normal stages (and sometimes Challenge Events) until the Mission timer runs out. You can cut the Mission short by spending Gems.

Every Mission has a "type" icon: a light bulb (intelligence), a magnifying glass (investigation), or a missile (firepower), which helps the player determine which character would be most suited for completing it. The higher the level your character is at, the better the character is and the higher they'll score. Once you have your character(s) selected, you are able to use popped Pigs as "reinforcements" to lower the Mission timer to a minimum of half the original runtime (which can easily cost thousands of Pig points, but those are really easy to amass).

When the Mission is completed, the result screen bar fills up, earning you a key for every "level", up to five total (you always automatically get one key regardless of performance). You also (usually) have the option to watch an ad to earn one additional key. These keys are used to unlock the five prize boxes presented to you. The potential prizes are quickly shown before being wrapped in gift boxes and spun around randomly, thus you must blindly select a present and hope for the best. If you don't have enough keys to unlock all five prizes, you can spend Gems (because of course you can) to collect the remaining presents (10 for Easy, 20 for Medium, and 30 for Hard), but this is really only worth it for unlocking new characters or if you ''really really'' need that [[Super Rareium]] ''right now''.

Given how many characters you can amass, this is a pretty simple way to gather Materials, tons of Coins, and even Gems over time with minimal effort.

===Ads and upsells===
[[File:ABTF-screen BuyGems.jpg|right|thumb|300px|Keep in mind the average, decent Accessory costs are roughly 400 Gems. Better ones 800~1000 or so.]]
It's a free game, so how does Rovio make its money? By copious amounts of ads (largely for other games) and by enticing you to spend real currency on in-game currency.

The ads can actually have a gameplay effect, in a disturbingly clever move. After completing any stage, you are given the option to watch a short video ad; doing so doubles your end-of-stage rewards. Similarly, when opening a Daily Reward, you can watch an ad to double the reward. Like we already said, upon completeing a Space Bridge Mission, you can watch an ad to obtain an extra key. When choosing a partner for a stage, you will also get a prompt to watch an ad; doing so gives your partner a one-stage stat boost and ups the amount of time they can stay in-play. However, you can only watch so many ads within a set amount of time, so choose which bonuses you go for wisely. You can also watch an ad to repair a character instantly; there does not appear to be any limit to this. And of course, ads may pop up anyway unless a purchase is made.

Spending real monies allows you to buy large numbers of Gems, which are used to buy Accessories, speed up character upgrades and repairs, interrupt the Eggbot terraforming to make a stage playable sooner, and about a billion other small things all over the game. Gem packages range from 150 for $4.49 US to 5200 for '''''$99.99''''' which what the hell who even spends that much money on these things?! And considering that mere ''accessories'', can run up to 1000 crystals, with most of the "buddy character" ones in the 850 range? Yeesh. From time to time there will be "sales" which either cut the prices down a bit or give you more Gems in each package, but come on.

Depending on who you ask, according to many reviewers, if you had to do a wipe or ever lose your files for some reason, you can lose all your progress. People have gotten their characters leveled up to the max. Which costs hundreds of thousands of gold coins or thousands of gems (read: lots and lots of grinding or real monies) only for it to be all for naught. But now that's not much of a problem since you can cloud save your progress with the Game Center on IOS or a Facebook account on Android.

{{-}}

===Challenge Events===
Starting in late 2015, the game introduced Challenge Events, five-to-ten-day-long themed events with the lure of prizes including unique unlockable characters and Accessories. While sparse at first, by mid-2016 events were popping up ''really'' frequently. Now it's continuous scheduled event after event.

[[File:ABTF-screen ChallengeEvent.jpg|left|300px|thumb|]]

Each day of an Event, the player is pit against 19 randomly-selected others at the same level (across the whole player base!) in a race to tally the most points within 24 hours by destroying as many of a specific object or enemy as possible in separate event stages. Entering a Challenge stage takes one "battery" of energy from the Challenge selection; the player starts with four, and spent batteries will recharge after an hour, one at a time. ''Of course'' you can spend Gems to speed up the process and instantly go back to four full batteries, but that cost increases every time: the first recharge costs 10 Gems, the next 20, then 40, 60, 80, then up to 100 for each recharge. Thankfully, that charge resets to the lowest amount each new day of the event.

In the earliest events, players could only take a single already-unlocked character and an [[Energonicon]] into the event with them. Eventually this changed, and depending on the event, you might be able to choose from your entire roster of unlocked characters, only certain members you've unlocked that match the event theme, or even "trial" characters you don't have yet who you can permanently unlock for the first time through the event you're playing there and now. Sometimes you can choose two characters and swap back and forth between the two (with a delay in recall time, of course). In some events, choosing characters from specific Teams and a specific Energonicon will add a percentage bonus to your final score, though given the potential dangers, one must take care to decide if the bonus is worth it if the bonus-giving characters aren't well-suited to taking out the target of choice for the day.

In 2017, the bonus scoring was changed to use "Sparks" won in Daily Challenges and awarded as Event prizes. By spending Sparks, you could "promote" a character, giving them an extra 5% bonus to your score per "rank" at the end of a run. Naturally, the higher the rank, the more Sparks you need. Selecting characters from the bonus Squad (which does not change for the duration of the event) gives them a multiplier to their Promotion bonuses, quadrupling the score.

Challenges are rewarded with Tokens, earned by reaching certain target milestones (milestones and prize amounts now vary from event to event), and according to your rank at the end of the 24-hour period (from 1000 to 100). These Tokens carry over from prior days' challenges up until the end of the promotion, and can be spent on prizes, including new characters, instant level-ups and accessories for select characters, Sparks, and Coins. Accessories are often less costly to obtain in Challenges than via normal Gem purchase. There is a 1-day token exchange period after each event ends, so some can spend the tokens they may have won from the final day's competition... and any ''new'' Tokens awarded through other means during the exchange period.

Originally, the milestones were consecutive 10 to 100. up to 550 tokens each day. Occasionally, mini-events give more token amounts than usual. But with the current token system, the maximum tokens possible per day are about 2000! But the final three milestones are ''impossible'' to reach without ''two'' highly-promoted characters of the same squad and/or hundreds and hundreds of gems!

Tokens are not currently able to be saved between different Challenge Events, but representatives from Rovio/[[Exient]] had raised it as a possibility, especially given how frequent the events have become. A year later, and they haven't done it. So pfffffft.

:''For a rundown of the history of Challenge Events, see [[Angry Birds Transformers (mobile game)/Challenge Events]].''

{{-}}

===Daily Quests===
[[File:ABTF-screen DailyQuest.jpg|right|thumb|300px|]]
Starting in September 2016, the game added Daily Quests, which are like the normal Achievements, but on a much smaller scale. Every 24 hours (starting at midnight via the clock on the player's device), eight randomized Quests are opened up, each earning a small prize for completion.

Quests can range from simple stuff like visiting a certain area so many times, destroying enough Pigs or blocks, creating enough items at the Lab, etc, to more difficult feats like pulling off enough slow-mo [[Monolith]] dodges, entering Astrotrain while scrambled, or racking up enough damage while in fast-forward at the [[Piggy Island|Cobalt Plateaus]]. The prizes are similarly random, with Pig Points, Coins, Gems, Materials, and even Tokens (only during Challenge Events) available.

There is also a ninth Quest with a four-part prize, earned only by completing all eight other Quests within the 24 hours.

With the introduction of Sparks, many quests were dropped completely (but some of them made a comeback). Currently, these Daily Quests are always in the mix:

* Collect 30 Energon cubes
* Pop 300 of any type of Pig
* Thank 5 buddies after events
* Visit the Pig lab and craft something

The final prize is always a generous 10 gems, 250 pigs, 15000 coins, and <s>500</s> 400 spark.

===Daily Reward===

===Jenga stage===
Down at the beach, there's the Jenga stage, shaped like the large [[Hal|Grimlock Bird]] Jenga toy that you could buy in stores. This mini-game remains locked until you use an unlocking code found in any of the ''Angry Birds Transformers Jenga'' toys.

Once open, this stage is a fair bit different. First you pick a Driver and a Gunner from a fixed set of characters (unaffected by who you have unlocked or away on Missions or upgrading). The Driver then travels along a path, gathering free-floating Coins and smashing through block towers. There are holes in the path, so sometimes you need to hit the turbo button for a burst of speed to carry you over. The turbo boost will drain quickly, so overuse can leave you dry when the big jump comes up. The goal is to gather as many coins and clear out as many blocks as possible and make it to the end for a higher score. Falling into a pit doesn't end the level, it just ends the Driver's turn and makes the Gunner's turn that little bit more difficult.

The Gunner then runs through a different path further out, and their job is to clear out as many blocks from inside the giant Grimlock Bird frame with their firepower. Naturally, this is easier if the Driver has cleared out the block towers that stood between the Gunner path and the frame. The more blocks that are destroyed or at least knocked completely out of the frame, the higher your score.

So why do this? Your Jenga scores accumulate over the course of 24 hours, and reaching 300 points nets you a prize. Often this is just a sum of Coins, no big whoop. But it's worth checking back every day, because the prize changes every 24 hours, and sometimes it's a small cache of Gems. Spending five minutes to get 10 Gems isn't bad, given how stingy the game can be with giving away the premium currency. Also, what happens in Jenga mode counts towards your Daily Quests: every mile you walk or drive, every block you smash, and every time you finish the "event". It can be a very quick way to knock out a couple of Quests at no cost other than a few minutes' time.

{{note|Bumblebee seems to be the best choice for the Driver, while Bludgeon works best as the Gunner thanks to his wide multi-shot cannon, though characters with rapid-fire attacks can really clean up if they can equip explosive rounds (like Energon Starscream). The available characters in Jenga mode have changed over the course of the game, eliminating certain characters whose weapons are designed for easy mass block destruction.}}
{{-}}

===Sparkrun===
[[File:ABTFScreen-Sparkrun.jpg|thumb|250px]]
Introduced March 2017, the Sparkrun lets you earn Spark (Only Spark; you don't earn any pigs or coins in this mode) by destroying everything you can in a special extra-long stage that goes through five random areas, with transitions through caves. You select three characters, and should your first 'bot go down, the next one you selected takes his place. You can also use a random character specially power-boosted for the Sparkrun. Promoted characters can also be used to increase the final score, which you'll need as they may not be enough stuff to get all the Spark in the level alone. Earn enough spark and the next difficulty level will be unlocked, each level adding 10 additional Spark to the initial 100, and increasing the damage of offensive pigs.

Gold blocks give the most amount of spark points, so be sure to destroy all of them!

Watch out for pigs with special buffs, like those that deal painfully more damage, regenerate health, shielded pigs immune to small arms fire, fast pigs, and health buffed pigs!

The Sparkrun can be played once a day, but can be reactivated for 100 gems.

As of a June 2017 update, many improvements were made. All enemies and missiles now give points when before only ground pigs and blocks gave points. Spark scoring has been rebalanced, making it easier to earn the max amount of Spark in higher difficulties. A fourth character slot can be unlocked for 1000 gems. And more importantly, the game is much, much less likely to crash in the middle of a Sparkrun. However, as players continued to advance in the game and "max" out their team of four characters at full promotion (140% x4) they realized the maximum difficulty in Sparkrun ended at 160. It was not possible to advance beyond difficulty 160 and the maximum reward of 1690 Sparks were incredibly rare to obtain due to the limited number of points that could be scored (the 5 levels in a Sparkrun course + the interconnecting caverns were completely random).

In a February 2018 update, a fifth character slot was added and available to be unlocked (permanently) for 2500 gems. The difficult ceiling was again raised beyond the previous maximum (160) with increasing Spark rewards. In the same update, the maximum promotion of characters were also raised (increased from 140% to 175%) which made it possible to once again score enough points to obtain the max Sparks available in a single Sparkrun.

===Crates===
In a September 2017 update, Crates were introduced which give various prizes, which fall under five rarities. Steel Crates give common, uncommon, or rare prizes that can be claimed for free every 24 hours or purchased for 15000 coins each; ''finally'' something to spend the coins you've stockpiled in the millions on. Opening ten at a time gives a guaranteed Rare prize. Gold Crates can give rare, epic, or legendary prizes, and can be purchased for 200 Gems each. Opening ten at a time is 5% off and gives a guaranteed epic prize.

Some of the possible prizes by rartiy:
*Common: Coins, 1-star accessory, Pigs, Tokens (~30~), Gems (2-3), Materials
*Uncommon: Coins, Materials
*Rare: Coins(~14500~), Spark, Tokens, 2~3-star Accessory upgrade
*Epic: 3-star accessory, 3-star accessory upgrade, Gems (~200~)
*Legendary: Instant upgrade, new Bot

Speaking of accessories, this update revamps the accessory system; Gem costs are significantly reduced, although this means token costs of accessories in Challenge Events is double the gem cost. New accessories are introduced (and old accessories from waaay back in 2014 are re-introduced). Accessories have five ratings, and can be unlocked or upgraded from crates.

===Shockwave's Spire===

Thought opening Gold Crates was a gamble? Well this new feature introduced December 2017 is really a gamble! Shockwave's Spire is essentially the same as ''Angry Birds 2'''s Tower of Fortune. There are several floors that each have four cards from which you pick one and get various prizes. The higher you go, the better the prizes and higher the rarity, all the way to legendary prizes at floor 90! And a guaranteed accessory every 5 floors! You can exit anytime and claim the prizes in the stash. '''''But''''' if you pick a pig card, you will lose them all! Unless you pay gems to keep playing. The gem cost will naturally increase significantly each time you make a gambling blunder.

Once you exit, Shockwave's Spire will not be available to play again (not even gem skips!) until the next day.

Be careful not to form certain habits and throw in way too many gems (and money).

==Notes==
* [[FIRRIB|Frenzy is red, Rumble is blue.]]
* This is the second ''Angry Birds'' crossover game, the first being with the undisputed king of cross-promotion, ''[[Star Wars (franchise)|Star Wars]]''.
* This is also the second 3D ''Angry Birds'' title, with prior games using 2D graphics save the racing game ''Angry Birds Go!'' (which also got a [[Hasbro]] toyline).
* You can alter a device's time to make the upgrades, Missions and other timed aspects go faster, although if you go too far or revert to current time, you'll get an error message about "Time travel detected! Your characters have suffered" and you'll be slapped on the wrist by getting them downgraded in relation to how far away from real time you were. So maybe don't do that.

===References===
This game is loaded with tiny jokes and references to Transformers lore.

* The character designs pull from a broad mix of generations. While (obviously) [[The Transformers (franchise)|Generation 1]] gets the most representation, there are also elements from the [[Live-action film series|live-action movies]], ''[[Transformers: Rescue Bots (franchise)|Rescue Bots]]'' and ''[[Transformers: War for Cybertron (franchise)|War for Cybertron]]''. Each character also has a number of wearable accessories, many of which are based on wider ''Transformers'' lore. (See individual character pages for the rundown on each.)

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:43:08Z

Ddr2nite:

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:39:34Z

Ddr2nite: /* February 2018 ~ May 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:33:27Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-02-03T06:30:55Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-01-19T17:16:05Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-01-12T06:50:48Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-01-12T01:46:12Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-01-05T03:45:40Z

Ddr2nite: /* April 2017 ~ June 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2018-01-05T03:43:57Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-29T06:18:48Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-29T06:14:38Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-29T06:11:34Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-29T06:08:15Z

Ddr2nite: /* June 2017 ~ January 2018 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-24T01:14:39Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-24T01:12:34Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-24T01:11:34Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-24T01:04:49Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-24T01:01:32Z

Ddr2nite: Undo revision 1231384 by M Sipher (talk)

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-15T02:24:21Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.

Angry Birds Transformers (mobile game)/Challenge Events

2017-12-08T00:05:35Z

Ddr2nite: /* June 2017 ~ December 2017 */

The '''Challenge Events''' in the [[Angry Birds Transformers (mobile game)|''Angry Birds Transformers'' mobile game]] offered players the chance to unlock new characters, unique Accessories, and regular Accessories at a reduced "cost" by destroying key targets in special stages.

==Challenge Event History==
===December 2015 ~ February 2016===
*'''Halloween Competition''' ([[October 22]] ~ [[November 9]], 2015)
:In this first competition, the top three players that smashed the most pumpkins in regular stages each day would get [[Gem]]s, while all other players would get 10000 Coins. [[Red (AB)#As Nemesis Prime|Nemesis Prime Bird]] was ''not'' part of the competition, but was available as an in-app purchase during the Halloween season.

*'''Thanksgiving Challenge''' ([[November 20]] ~ [[November 26]], 2015)
: Unlock various prizes, including exclusive Pilgrim hats for select characters, through single-player challenges by popping flying pigs dressed as turkeys.

:After the event, several Black Friday deals popped up, from at-the-time cosmetic accessory bundles to discounted Gem packages to the Fire Bundle that contained the brand new character Rodimus at a low price!

*'''Holiday Challenges!''' (December 2015)
: The first ever Challenge Event combines the competition and challenges, and introduces Tokens and the battery system. Unlock [[King Pig|Shockwave Pig]] and a host of holiday-themed Accessories for various other characters by destroying holiday-themed objects.

*'''Challenge in C-Minor''' ([[January 24]] ~ [[January 31]], 2016)
:Obtain Accessories for [[Chef Pig|Soundwave]], Energon Soundwave and Soundblaster, with exclusive [[Rumble (AB)|Rumble]] Soundwave Accessory.

*'''Chinese New Year''' ([[February 6]] ~ [[February 16]], 2016)
: Unlock [[Red (AB)|Epic Optimus Prime]] and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

*'''Encore in C-Minor''' ([[February 24]] ~ [[February 27]], 2016)
:A brief, three-day re-run of the "Carnage in C-Minor" event to let you take a swipe at Accessories you may have missed the first go around.

===March ~ May 2016===
*'''Enter the Silverbird''' ([[March 12]] ~ [[March 19]], 2016)
[[File:ABTF-screen Silverbird.jpg|right|thumb|300px|Partly metal, partly real. Silverrrrbirrrrrd!]]
:[[Boss Pig]]'s head has been commandeered by the Eggbots and equipped with ''really'' powerful missiles. Defeating Boss Pig and flying Pigs earns points for Tokens. Prizes are various prior-existing accessories, with the new Autobird [[Silver]] as [[Windblade (G1)|Windblade]] as the ultimate prize.
:After this event, there is a chance that Boss Pig could pop up uninvited and unexpected in future events, carrying a real risk if your characters aren't suited for taking him on.

*'''Prime Target''' ([[March 24]] ~ [[March 31]] 2016)
:Pop as many Pigs as possible! Each day a new sub-set of Pig (balloon-head, flyers, etc) are worth 10 points a pop instead of the usual 1. All of the prizes are accessories for [[Moustache Pig|Lockdown]] and Energon Lockdown, including the event-exclusive Cannon and Rangefinder for regular Lockdown.

*'''Target: 2016''' ([[May 7]] ~ [[May 15]], 2016)
:This event brings some significant new changes: players can now take two characters instead of an [[Energonicon]], and points are gained only through energon cubes (10 points per cube) and priority targets. Using a character from the currently shown bonus squad will increase your points at the end of a stage by the shown percentage, which could be 25% ,50%, 75%, 100%, or even 150%, depending on the squad. Bonus Squads are changed every four hours. As for the prizes, Shockwave was available again for those who may have missed him the first time around, along with a handful of non-exclusive accessories for the Target: 2006 squad.

*'''The Angry Birds Movie''' ([[May 18]] ~ [[May 29]], 2016)
:Tying in with Rovio's theatrical film, ''The Angry Birds Movie'', this Challenge (along with all the other current Rovio games at the time) promotes the release of the big blockbuster with a new movie-themed app icon, loading screen, and point-earning smashable movie tickets and Billy signs. Prizes are a second chance at Epic Optimus and exclusive Coconut Helmets for Autobirds and Cowboy Hats for Deceptihogs.

===June ~ August 1016===
*'''Heatwave''' ([[June 4]] ~ [[June 12]], 2016)
:There are some small changes for this event: ''two'' bonus squad characters are required to get the full point boost. For example, using one seeker will only give a 37% bonus, while using both seekers will give the full 75% bonus. Point values are now 1 per popped pig, 5 per Mortar Tower, and varied for priority targets. The prizes are Heatwave's unique accessories, but the ''real'' prize is the Gem packages that would be normally be only available as in-app purchases.

*'''Acid Storm''' ([[June 18]] ~ [[June 25]], 2016)
:Back to one Transformer with an Energonicon, with points obtained only from current challenge targets. The prizes are the new Acid Storm and his ''Nemesis'' and [[Kremzeek]] accessories.

*'''Second Wind''' ([[July 2]] ~ [[July 12]], 2016)
:Second chance to get Windblade and her accessories. And the bonus Transformer point boost is back! Nothing new though.

*'''Seek and Destroy''' ([[July 22]] ~ [[July 31]], 2016)
[[File:ABTF-screen Seek&Destroy.jpg|right|thumb|300px|Good luck getting them all!]]
:Not one, but ''three'' new Seeker characters are introduced, at a whopping 4800 tokens each, so good luck unlocking more than one without spending a ''lot'' of Gems. The player can try out Skywarp, Starscream, and Sunstorm in the events. Points are obtained from smashing Seeker color-coded blocks, and 10 points for each current challenge block.

{{note|Starting from this Challenge Event, missing Tokens could be bought with Gems, though the exchange rate would vary. Any Accessories available with Tokens in these events also had their normal Gem prices slashed 50% for the duration of the event.}}

*'''Peace through Tyranny''' ([[August 4]] ~ [[August 9]], 2016)
:An event to get various Deceptihog accessories, including brand new [[Megatron (Armada)|Armada]] horns for both Megatron Pigs! Both a select Deceptihog and a select Energonicon give score bonuses.

*'''You've Got the Touch''' ([[August 13]] ~ [[August 19]], 2016)
:You've got the chance to earn [[Chuck (AB)|Rodimus]] and his accessories in this event celebrating the 30th anniversary of ''[[The Transformers: The Movie]]'', along with [[Blues|Prowl]] and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout! Rodimus is available at all times as a "trial" character for free if not yet unlocked, and his health is automatically filled up after every run.
:After this Event, Unicron Pig could pop up unannounced in future Challenge Events, just like Boss Pig. In fact, you could get one right after the other! Ugh.

*'''Medic!''' ([[August 23]] ~ [[August 29]], 2016)
: The chance to unlock the new character [[Terence (AB)|Ratchet]] and his unique accessories, along with Arcee and Airachnid (if not unlocked through missions yet). Points are awarded for destroying a specific block type each day. Ratchet is available at all times as a "trial" character for free if not yet unlocked, and the best part is his health is automatically filled up after every run, since he's not in your stable yet! Abuse this!

===September ~ November 2016===
{{note|Just before the next Event, Daily Quests were introduced. These mini-challenges, 8 per day, could offer Tokens as prizes, giving you the chance to earn even more than the Event would allow normally per day... it's all the luck of the draw there, though, as to what the Quests are and how much, if any! 
Oh, and also? At this point, they go '''absolutely nuts''' with the number of Events they run, sometimes with a mere 24 hours between the end of one's Token Exchange and the start of an all-new, un-advertised Event.}}

*'''Ride of the Valkyries''' ([[September 2]] ~ [[September 6]])
: ''Another'' chance to unlock Arcee and Airachnid, and their unique accessories, as well as another shot at Shockwave and his Accessories. Points are awarded for destroying a specific block type each day.

*'''Flight of the Bumblebee''' ([[September 8]] ~ [[September 12]])
: The focus is on Accessories for Bumblebee and High Octane Bumblebee, but also another chance to unlock Epic Optimus. The lack of downtime between events at this point has gotten ridiculous.

*'''Lock & Load''' ([[September 14]] ~ [[September 21]])
: Take a single character into the stage and shoot at specific targets. No Energonicons, no backups, but still a (hefty) bonus for using someone from the suggested Squad. The prize here is new character [[Bubbles|Ricochet]] and his accessories. Ricochet is available at all times as a "trial" character for free if not yet unlocked.

*'''The Blues Brothers''' ([[September 23]] ~ [[September 28]])
: Another chance to unlock Bluestreak and Prowl, as well as Windblade, and their unique accessories. Back to two swappable characters and an Energonicon, and blasting blocks of a target color for bonus points.

{{note|From this point forward, the scoring system changed slightly. Previously, you earned 1 point for every non-target Pig (and 5 for Mortar Towers), but from here on you also earned 1 point for every block destroyed and every piece of cyberformed scenery blasted. Depending on the Squad bonus, a good mass-destruction character might actually be better than using a bonus-earning character sometimes!

:Also from this point, ''every'' event has limited-time character bundles and gem sales. (yes, for real money). Any characters and accessories you'd already unlocked are replaced by a cache of Tokens equal to their original Token cost. }}

*'''2-Year Celebration!''' ([[October 5]] ~ [[October 14]])
[[File:ABTF-screen 2Year.jpg|right|thumb|300px|]]
:Two years of ''Angry Birds Transformers'', Who would have thought? Daily targets are worth premium points, and this time both Pigs ''and'' all blocks are worth 1 point apiece! Two swappable bots and an Energonicon, with point bonuses for picking the right ones. The big prize is [[Bomb (AB)|Drift]], who costs a whopping ''7500 Tokens'', but is free to play during the event. Yeah, you get nine days, but man. On top of that, you have the chance to unlock ''all'' of the prior event-only characters (but not Arcee, Airachnid, Prowl or Bluestreak, since they're also unlockable via Missions).

:Unfortunately, this Event also came with a major update that severely buffed the durability of all of the enemies in the game against direct attacks, making gameplay much, much harder (but was reverted later).

: Character Bundles were also available for sale (yes, for real money) during the course of the event, starting with Drift as part of a two-day deal, but soon moving on to the other past unlockables, one per day.

*'''Prime Time''' ([[October 18]] ~ [[October 24]])
: Using only the Prime birds (including Sentinel and Rodimus), go solo into a stage (no Energonicon either!) and pop the target Pigs for extra points. Squad bonuses still apply. You also get to try out Nemesis Prime Bird free, but ''not'' unlock him. The prizes are Epic Optimus and Rodimus and their accessories. The first several hours of the event were unplayable, as the game would crash after playing Heatwave's cutscene. Oops.

*'''[[The Smashing Pumpkins|Smashing Pumpkins]]''' ([[October 25]] ~ [[November 1]])
: Halloween and Nemesis Prime return! Two bots, one Energonicon, and a load of Halloween-themed stuff litters the stages, and every day one type of decor is worth extra points. Astrotrain and the Flying Pigs are decked out like witches too! [[Red (AB)#As Nemesis Prime|Nemesis Prime]], Skywarp and their accessories are the main prizes. There is also an assortment of Halloween-themed hats at 1000 Tokens a pop, every one giving a 10% Damage bonus to the wearer, and ''not restricted to a single character''. While most characters can only wear one to three of the eight available hats (some can't wear any of them), buying one hat unlocks it for ''every viable character'', which in some cases means you just got over a dozen Accessories in one shot! Now that's a deal!

*'''Time to Bludgeon & Brawl''' ([[November 3]] ~ [[November 9]])
: An all-Decepticon event, with a single character and Energonicon blasting the target color blocks each day. Prizes include regular Starscream, his Accessories (once/if unlocked), and the unique Accessories for Bludgeon and Brawl.

:Continuing to tempt players to part with their money, The game offered the "Special Event Bundle" during the course of the event. it contained 250 gems, Bludgeon's Sentinel accessory, and 2500 Tokens, all for the low price of $5.99.

*'''Thunderstruck''' ([[November 10]] ~ [[November 16]])
: An all-jet-Pig event, two swappable Pigs and no Energonicons. Any Seeker Pigs you have not unlocked are offered as free-to-play characters, so there's that at least! Destroy the key targets for extra points. Acid Storm is this Event's unlockable, as are the special Accessories for him, Thundercracker and Energon Starscream.

:The exact same Acid Storm Bundle available in the "Two-Year Celebration" event could be purchased during the course of this event, at $24.99, for those who may be really impatient or unable to play the Challenge Event for whatever reason.

*'''Happy Thanksgiving!''' ([[November 18]] ~ [[November 27]])
[[File:ABTF-screen Turkeys.jpg|right|thumb|300px|And yet, only at most the ''third''-oddest thing to ever happen in official ''Transformers'' product.]]
: Be thankful that you have to chance to unlock Sunstorm, accessories for most of the Energon-fueled characters (not Energon Soundwave and Starscream since they got prizes in prior events), and Pilgrim Hats. Only the "Energon" versions of characters are available to use, but Energonicon bonuses are back. Targets are primarily Pigs, including the Flying Pigs who've dressed up like cooked turkeys for the event.

:This event's "Special Event Bundle" contained a minimalist 150 gems, 10000 coins and 1000 tokens for $14.99. But from [[Black Friday (event)|Black Friday]], [[Moustache Pig#As Dead End|Dead End]] and several other character bundles were made available for sale, with new offers every 8 hours.

{{-}}

===December 2016 ~ March 2017===
{{note|From this point on, the point bonuses become... let's politely call it "complicated". Bonuses are ONLY given to characters who have been "Promoted", which you do by spending Sparks earned through Daily Challenges (or bought in Challenge Events). The higher their rank, the more bonus % they earn, and that bonus is granted '''any''' time they're used in an event. Moreover, if the character is part of the Squad Bonus selected for the entire duration of the event, their normal bonus will be multiplied (x2 to x4 depending on the event). Energonicon bonuses are gone.

:Also, Spark Bundles have joined the rotation of daily special event IAPs, ranging from $5.99 to $39.99, depending on the amount of gems and Spark offered.}}

===April 2017 ~ June 2017===
{{note|Looking for ''another'' thing to spend tokens on? You can now buy instant upgrades for characters in live events, even '''overpowering''' them if at max level! Higher level upgrades cost nearly as much as new characters though. In order to make these 50-8000 token upgrades achievable, the daily challenge token amounts have been increased up to 2500, although reaching the final milestones are impossible to reach without oodles of gems.

:Also, Spark from daily quests have been reduced from 500 to 400, possibly because you can get 100 or more from the Sparkrun.}}

==Notes==
[[File:ABTF-screen FreeTry.jpg|right|thumb|300px|Try a Bomb for free! ...erm, let us rephrase that...]]
* In almost every event, you earn 1 point for every Pig you pop or block you break, plus the larger point totals for bringing down Boss Pig or Unicron Pig, whether they are the choice target for the day or not.
* Challenge Events focused on new characters often allow you to play as those characters for free if you have not already unlocked them. While their Level will be set (typically Level 8, but sometimes 15!) and they won't have any augmenting Accessories or gain Squad bonuses (even if they're part of the current bonus Squad!), there is the advantage that their health restores to full each time you take them into a Challenge level, sparing you some ad-watching time... even if they were knocked out!
* Sadly, Tokens earned in one Event are lost at the end of the Token Exchange period following the Event, and will not carry over into the next one. [[Exient]] reps have said they are considering allowing players to "bank" Tokens between events, but no action has been taken on this yet.
