Peggle is a casual puzzle video game developed by Sukhbir Sidhu and Brian Rothstein of PopCap Games. Initially released for Microsoft Windows and Mac OS X systems in 2007, it has since had versions released for Xbox Live Arcade, PlayStation Network, the Nintendo DS (with the help of Q Entertainment), Windows Mobile, the iPod, the iPhone OS, Zeebo and Android, the game has also been ported as a Java application, and an extended minigame incorporated into the massively multiplayer online game World of Warcraft. A sequel was released in September 2008, titled Peggle Nights.
Inspired by pachinko, each level of Peggle challenges the player to shoot a limited supply of balls at a field of colored pegs to clear out specifically marked pegs while attempting to achieve a high score through skilled shot planning. Special powers associated with a number of cartoon "Peggle Masters" can be activated to aid the player in this task. Peggle initially sold slowly but was boosted by the inclusion of a specially designed demonstration in Valve's The Orange Box, and has since enjoyed over 50 million downloads from the Internet. Both its release on Xbox Live Arcade and the iPhone OS have enjoyed similar success.
