Pocket Bandit is a slot machine game for Android. It features a retro style with three reels and ten stops, and is modelled after the classic, mechanical fruit machines of the early 20th century and emulates devices such as the Mills Novelty QT Chevron, Mills Novelty Vestpocket, Groetchen IMP trade simulator, Pace Comet, and Liberty Bell. Unlike the original machines, it also includes elements of skilled and strategic play.
