Ms. Pac-Man is a popular arcade game released by Midway in 1981. This sequel to Pac-Man differs from its predecessor on the fact that there is more than one layout of paths involved. Every two or three levels, the map changes with intermissions in-between that illustrate the courtship of Pac-Man and Ms. Pac-Man. It was one of the more successful of early arcade games and was even more popular than the original.
