Angry Birds Transformers (mobile game)/Challenge Events

The Challenge Events 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

• Halloween Competition (October 22 ~ November 9, 2015)

In this first competition, players could smash pumpkins for the chance to win Gems each day.

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.

• Holiday Challenges! (December 2015)

Combining the competition and challenges for the first time, along with introducing tokens, Unlock 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 Soundwave, Energon Soundwave and Soundblaster, with exclusive Rumble Soundwave Accessory. Had a brief encore run as well.

• Chinese New Year (February 6 ~ February 16, 2016)

Unlock Epic Optimus Prime and China-themed accessories for various characters by blasting specific China-themed objects littering the battlefield.

• Enter the Silverbird (March 12 ~ March 19, 2016)

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 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 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 (Ultra Magnus, Galvatron, Jazz).

• 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) 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 coconut helmets for Autobirds, cowboy hats for Deceptihogs, and a second chance at Epic Optimus and two exclusive accessories.

• 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 Ramhorn, Eject, and axe 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)

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.

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 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 Rodimus and his accessories in this event celebrating the 30th anniversary of The Transformers: The Movie, along with Prowl and Bluestreak. (For those who haven't obtained them from missions, apparently.) Watch out for Unicron Pig shooting flaming piggies from his snout!

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 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.

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!

• Ride of the Valkyries (September 2 ~ September 7, 2016)

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.
