An iPo game is a video game playable on the portable music player, the iPod, from Apple Inc. The original iPod had the game Brick (originally invented by Apple's co-founder Steve Wozniak) included as an easter egg, or a hidden extra feature, and 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.
