Angry Birds Rio is the third puzzle video game in the Angry Birds series, developed by Rovio Entertainment. Based on the wildly successful Angry Birds, Angry Birds Rio was released for devices using Apple\'s iOS, Google\'s Android and Mac OS X in March 2011. The game was released as a marketing tie-in with the 20th Century Fox animated film Rio, and was promoted along with the movie. While utilizing the same basic gameplay as the original game, Angry Birds Rio added a number of new elements, most notably the first use of boss levels. The game is consistently one of the top downloaded applications on both the App Store and the Play Store.In Rio, the Angry Birds have been kidnapped and taken to Rio. Just as in the original Angry Birds, players use a slingshot to launch birds at nearby structures, with the intent of hitting targets located on or within them. Instead of the pigs that have stolen eggs, players must now rescue caged exotic birds or defeat Nigel\'s marmosets, depending on the level being played. Because of the game\'s setting, several characters from Rio make appearences. Blu and Jewel both feature as types of bird exclusive to this game, along with all the existing birds from the series. Jewel can be launched much further than other birds, and can fly in a horizontal line until hitting an obstacle with her special ability. Blu\'s ability will make him attempt to fly for a few seconds, darting around a small area as he does so. The game also includes the first boss fights to appear in the series, when the player uses the birds to defeat Nigel, the main antagonist from the film, as well as Mauro, the leader of the marmosets. In other levels, Luiz helps defeat the marmosets and destroy things to get the player extra points. as well as hidden items to collect as the player progresses through the game.
