Angry Birds is a puzzle video game developed by Finland-based Rovio Mobile in which players use a slingshot to launch birds at pigs stationed on or within various structures, with the intent of destroying all the pigs on the playfield. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apple's iOS in December 2009.

Since that time, over 12 million copies of the game have been purchased from Apple's 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. Rovio Mobile has supported Angry Birds with numerous free updates that add additional game content, and the company has even released stand-alone holiday versions of the game.

Angry Birds has been praised for its successful combination of addictive gameplay, comical style, and low price. Its popularity led to versions of Angry Birds being created for personal computers and gaming consoles, a market for merchandise featuring its characters and even long-term plans for a feature film or television series. With 100 million downloads across all platforms, the game has been called "one of the most mainstream games out right now" and "one of the great runaway hits of 2010".
In Angry Birds, players take control of a flock of birds that are attempting to retrieve eggs that have been stolen by a group of evil green pigs. On each level, the pigs are sheltered by structures made of various materials such as wood, glass and stone, and the object of the game is to eliminate all the pigs in the level. Using a slingshot, players launch the birds with the intent of either hitting the pigs directly or damaging the structures, which would cause them to collapse and kill the pigs. In various stages of the game, additional objects such as explosive crates and rocks are found in the levels, and may be used in conjunction with the birds to destroy hard-to-reach pigs.
