Throughout the game's operation, special events become available to all players for a limited amount of time, with new ones added after each subsequent update. Major events provide opportunities to unlock either Matilda and her anger management students, members of a bird rock band, or a handful of newly introduced, powerful birds. In such events, players must gather special event currency throughout the game map, battles and in Bird Town as well to earn more and more prizes, while being encouraged to hatch as many premium eggs as possible to increase their chances of earning a certain event bird, which would reset once he/she is hatched. Other shorter events, such as the Pirate Brawl, has players racing to win as much event currency as possible across a couple of days to earn helpful rewards. Reception Julie Muncy of Wired criticized the game's gameplay ("you slingshot your birds in classic Angry Birds fashion, sending them careening around tiny combat arenas [...] None of this really works."), sound design and pop culture references, referring to it as a "cash-in." Pavan Shamdasani of the South China Morning Post was similarly critical of the game, noting its "unoriginal elements" in both gameplay and visual design. Emily Sowden of Pocket Gamer was more positive in her review, writing that "Angry Birds Evolution is a decent game at first before the usual free to play problems comes knocking."
