Angry Birds Evolution, later renamed to Angry Birds Evolution 2020 and currently Angry Birds Evolution 2022, is a free-to-play 3-D turn-based role-playing puzzle game that was released worldwide by Rovio Entertainment on June 15, 2017. The game plays similar to Angry Birds Epic, also developed by Chimera Entertainment, with the exception that a player is slinging birds toward the enemies to defeat them instead of using weapons. The game has received the Editor's Choice award on the Google Play Store. According to mobile research firm Sensor Tower, it has grossed more than $30 million worldwide, as of July 2018. History The game was first discovered in July 2016 under the working title TNT when the fan website AngryBirdsNest began hosting an open beta for the game. The open beta period ran from July 11, 2016 to August 3, 2016, and was only available on iOS. After the beta ended, the game was soft-launched in Hong Kong on August 17, 2016, then was released in more Asian countries in October 2016. On June 15, 2017, the game received a final, global release. Gameplay This game is a turn-based role-playing game, like Angry Birds Epic, but its battles incorporate the pinball-like elements of Angry Birds Action!, in the sense that the player launches birds at a handful of pigs in a rectangular battlefield, bouncing off of its boundaries, obstacles and enemies strategically to cause as much damage as possible and achieve victory. Each pig will attack after a certain number of turns pass, while birds will be able to use a special move, determined by their plumage color, once their fury builds up after a series of turns. Defeating all pigs would result in victory while allowing the pigs to drain the birds' shared health bar will result in a defeat, unless the player decides to pay gems to replenish some health and keep going. Winning a battle will grant the player rewards, such as coins, evolution material and eggs. In most regions of the game world, eggs won from these battles will only produce a bird of a particular plumage, depending on what zone the battle was fought in (i.e. battles won in the Yellow Desert would produce eggs for yellow birds). Eggs can also be hatched at the Bird Town to obtain new characters, with a chance to collect characters from The Angry Birds Movie, such as Red, Chuck, Bomb,
