Puckman is a 1981 unlicensed Pac-Man clone for the Apple II.
Released approximately a year after the initial arcade version of Pac-Man, the player controls a small character who must move about a maze munching dots. All graphics are tilted 90 degrees. Four ghosts constantly harass the player, but if they eat one of the four power pellets located in each corner of the screen, the ghosts temporarily become vulnerable, and can be eaten by the player. The player must much all dots to advance to a more difficult level. The player starts with 3 lives, and if all are lost, it's game over.
