 > Pac-Man is a maze action game developed and released by Namco for arcades in 1980. The player controls Pac-Man, who must eat all the dots inside an enclosed maze while avoiding four colored ghosts. Eating large flashing dots called "Power Pellets" causes the ghosts to turn blue, allowing Pac-Man to eat them for bonus points.
