Angry Birds

Angry Birds is a puzzle video game developed by Finland-based Rovio Mobile. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apples iOS in December 2009. Since that time, over 12 million copies of the game have been purchased from Apples App Store, which has prompted the company to design versions for other touchscreen-based smartphones, such as those using the Android operating system, among others.
