An iPod click wheel game or iPod game is a video game playable on the various versions of the Apple portable media player, the iPod. The original iPod had the game Brick (originally invented by Apple co-founder Steve Wozniak) included as an easter egg hidden feature;[1] later firmware versions added it as a menu option. Later revisions of the iPod added three more games in addition to Brick: Parachute, Solitaire, and Music Quiz.[2] Apple later offered iPod games for sale through the iTunes store. These games should not be confused with games for the iPod Touch, which require iOS and are only available on Apple's App Store.
