The original 1981 arcade machine.

Ms. Pac-Man is an arcade game that is the sequel to the original Pac-Man arcade game.

Gameplay Info

The goal of the game is to have Ms. Pac-Man eat all of the on-screen dots and avoid the attacks of the four ghosts. The gameplay is very similar to Pac-Man, although there are some differences:

  • The game has four different colorful mazes that alternate. The orange maze appears in levels 1 and 2, the light blue maze appears in levels 3, 4, and 5, the brown maze appears in levels 6 through 9, and the dark blue maze appears in levels 10 through 13. Starting with level 14, the last two maze configurations alternate between each other every 4th level.
  • The orange ghost is now named "Sue".
  • The ghosts do not move in "scatter" and "chase" cycles as they did in the original game; Blinky and Pinky will move randomly and Inky and Sue will head for their "scatter" corners only during first behavior mode of a round. From there, while they will change direction occasionally, they will remain in constant attack.
  • There are no longer any paths that the ghosts cannot travel through.
  • The sound effects and music have been changed.
  • The intermissions have been changed. The first one shows how Pac-Man and Ms. Pac-Man first meet. The second shows the two chasing each other around the screen. And the third shows Pac-Man and Ms. Pac-Man awaiting the arrival of Pac-Baby.
  • The fruit symbols now include the cherry, strawberry, orange, pretzel, apple, pear, and banana, and they move around the screen instead of remain stationary below the ghost pen, starting from one of the tunnel entrances and leaving through another if not eaten. After the banana appears, the fruit prizes are chosen at random.
  • Tunnels do not slow the ghosts down after Round 3.

Scoring System


Originally, Ms. Pac-Man started as a hack called Crazy Otto by General Computer Corporation featuring a Pac-Man like character with a blue eye and legs.To avoid previous lawsuits with Atari, General Computer Corporation presented the game to Bally Midway for approval of release. Bally-Midway, impatient for Namco to release Super Pac-Man, purchased Crazy Otto instead for their own release. Inspired by an intermission in Crazy Otto, Bally Midway then changed a quantity of details from Crazy Otto, and named it Ms. Pac-Man after many name changes. As Ms. Pac-Man/Crazy Otto was developed & published without Namco's permission, after many years Bally Midway was forced to turn the rights to Namco. Ms. Pac-Man, along with many others including Baby Pac-Man, Jr. Pac-Man, and Professor Pac-Man caused the termination of the official licensing agreement between Namco and Bally Midway.

Ms. Pac-Man was never released in any arcade form in Japan, though many console releases have been produced later.

Home Ports

NOTE: The Tengen version for the NES, which was also ported to the Sega Genesis, the Sega Master System, and the Super NES, has multiple mazes, scrolling screens, and a two-player mode where both players compete against each other on the same screen at the same time, with Player 2 controlling Pac-Man. It also ends after the 32nd screen with a fourth intermission.

Namco Museum port

Similarly to Pac-Man, Ms. Pac-Man also saw a Namco Museum port in 1996. This version, like Pac-Man, used the source code from the original game and was perhaps the most frequently ported version for quite some time. Some things about it were changed however, and this version sees all of the applicable changes Pac-Man had, plus:

  • Blinky and Pinky do not move randomly during the first behavior mode; they head to their original "scatter" corners as they did in Pac-Man.
  • Furthermore, the "scatter" and "chase" cycles are restored in the game.
  • The tunnel slowdown effect does not occur until a ghost reaches middle of the tunnel (in the original game, they are slowed down at the entrance).
  • The tunnel slowdown occurs in all rounds.
  • Most of the sound samples have their pitch raised.
  • The background sound effect does not change as the player gets closer to finishing the maze.
  • In the original game, if the player inserted a credit before Blinky appeared on the introduction screen, the first maze would appear blue. This is fixed for this version of the game.

This version of Ms. Pac-Man was featured in the following games after its initial release:

  • Namco Museum 64 - 1999
  • Namco Museum (Dreamcast) - 2000
  • Namco Museum (GBA) - 2001
  • Namco Museum (PS2, GameCube, Xbox) - 2001
  • Pac-Man World 2 - 2002
    • In the GameCube version, the maze does not flash when completed, and all mazes use the first maze's color scheme.


  • This is the first Pac-Man game not to be developed by Namco.
  • Blinky and Pinky moving randomly at the start of each round is achieved by them being programmed to randomly target each of the original four "scatter" corners of the maze.
