text: Versions and sequels Peggle was first released for Windows on February 27, 2007. Peggle Extreme was packaged with the Windows version of The Orange Box, featuring levels inspired by Half-Life 2, Team Fortress 2, and Portal. It includes ten levels with one Peggle Master and five Challenges. Peggle Extreme was eventually made free to download for anyone with a Steam account. The game was developed in conjunction with Valve after PopCap's Teams learned that Peggle was played often at Valve's offices and that the company had helped to promote the game on Steam. PopCap proposed a version that would pay tribute to Valve's games, which Valve readily warmed up to, helping PopCap with its development, including providing graphical assets and artwork.
  Peggle has been ported to Xbox Live Arcade, the PlayStation Network, the iPod, and iOS. The Xbox Live Arcade and PlayStation Network versions includes the "Peg Party" mode in which up to four players can compete simultaneously. The Xbox Live Arcade, PlayStation Network, and iOS versions include the "Duel" mode, with the iOS version having the players share the iPhone between turns. Peggle has also been ported as a minigame inside World of Warcraft in the form of a free, downloadable addon. It features levels based on the game, though including a limited set of Peggle Masters to use. Warcraft players can also use Peggle to decide how to distribute loot from successful raids or dungeons. Subsequently, in July 2009, a free standalone, ten-level edition of Peggle themed around Warcraft in a similar manner as Peggle Extreme was released.
