Angry Birds (video game)

Angry Birds is a 2009 puzzle video game developed by Rovio Entertainment and published by Chillingo. Utilising touchscreen interaction, it revolves around players using a slingshot to launch limbless birds at green pigs stationed in various structures, with the intent of defeating all of the pigs on the playing field. As players advance through the game, new types of birds become available, some with unique abilities.

Rovio had developed over 50 games prior to Angry Birds. The game was conceived as a result of the development studio nearing bankruptcy; the concept was primarily inspired by sketch of stylized wingless birds illustrated by designer Jaakko Iisalo, and its gameplay is based on Crush the Castle, another 2009 puzzle game.

Angry Birds was originally released for mobile devices on December 11, 2009, with several ports and patch updates having been produced thereafter. It has received critical acclaim and is considered one of the best video games of all time. It was a commercial success, being downloaded over 50 million times as of 2010 and appearing on several app store top charts for long periods of time, and has won multiple awards. The success of Angry Birds spawned a media franchise, including numerous television series, print media, amusement parks, and feature films. Its first spinoff, Bad Piggies, was released in 2012. A sequel, Angry Birds 2, followed in 2015.

In early 2019, the game was discontinued alongside many of its early successors. In response, a remake titled Rovio Classics: Angry Birds was released on March 31, 2022, but was discontinued on February 23, 2023.
