Pac-Man is a variation of the original arcade game, which Namco released in 1980, and features similar—but not identical—gameplay. The player uses a joystick to control Pac-Man, navigating him through a maze of consumable dashes called Video Wafers, opposed by a quartet of multi-colored ghosts. The goal of the game is to consume all the wafers in each level in order to proceed to the next one in search of the highest possible score. (wikipedia.org)
