Ms. Pac-Man (1981) grew from a Pac-Man enhancement kit into Midway's best-selling game, with four mazes, moving fruit and less predictable ghosts.
Ms. Pac-Man began as Crazy Otto, an enhancement kit for Pac-Man made by the team at General Computer Corporation, which Midway licensed and released officially. It keeps the original's pellets and power pills but rotates through four different mazes, sends bonus fruit bouncing around the board, and gives the ghosts more varied behaviour so fixed patterns work less reliably. It outsold Pac-Man in North America, and many players consider it the better game.
Ms. Pac-Man began as an unauthorised enhancement kit called Crazy Otto, developed by a group of MIT students at General Computer Corporation. Midway licensed it from them when they discovered it in 1981, and worked with Namco to release it officially. The game featured maze variations, faster gameplay, moving fruit, and semi-random ghost behaviour — improvements so significant that many players and designers prefer it to the original.
