Angry Birds (later renamed to Red's First Flight and formerly known as Angry Birds Classic) is a 2009 casual puzzle video game developed by Finnish video game developer Rovio Entertainment. Inspired primarily by a sketch of stylized wingless birds, the game was first released for iOS and Maemo devices starting in December 2009.[1][2] By October 2010, 12 million copies of the game had been purchased from the iOS App Store,[6] which prompted the developer to design versions for other touchscreen-based smartphones, most notably Android, Symbian, Windows Phone, and BlackBerry 10 devices. The series has since expanded to include titles for dedicated video game consoles and PCs. A sequel, Angry Birds 2, was released in July 2015 for iOS and Android. Around April 2019, the original game was removed from the App Store.[7] A paid recreation of the game's content from 2012 was released as Rovio Classics: Angry Birds on March 31, 2022,[8] but later on, Rovio mentioned that they were removing it from the Google Play Store on February 23, 2023, and retitling it as Red’s First Flight.
