Pac-Man vs Ms. Pac-Man: every difference explained

The sequel was built by outsiders in Massachusetts, adopted by Midway and eventually embraced by Namco. It plays faster and looser than the original, and the differences go deeper than a bow.

Origins: a modification kit that became a sequel

Ms. Pac-Man began as Crazy Otto, an enhancement kit created by General Computer Corporation (GCC), a group of MIT students who had previously been sued by Atari over a Missile Command speed-up kit. Midway, hungry for a sequel Namco was slow to deliver, licensed the kit, swapped the character sprites, added the bow and lipstick and released it in early 1982. Namco initially objected and later accepted it into the official canon. The broader franchise chronology is in the full pacman timeline explained.

The mazes

The original's single 28 by 31 maze is described in pacman maze dimensions explained. Ms. Pac-Man's four mazes are slightly different sizes, have two or more tunnels (one has four), and are coloured differently so the player always knows which is active. The first maze is used for boards 1 and 2, the second for 3 to 5, and the third and fourth alternate in pairs of boards after that. Because tunnels are more numerous, escapes are easier but patterns are far less valuable.

The ghosts

Three of the four ghosts keep their original targeting rules, but GCC added randomness: for the first few seconds of a board and immediately after each scatter-chase reversal, ghosts choose directions at random. That small change breaks the long patterns that make a perfect original game possible (see pacman ghost ai explained). Sue replaces Clyde, with identical logic; she was recoloured purple in some later versions.

Fruit

Instead of appearing in one spot, fruit enters through a tunnel, bounces around the corridors and leaves through another tunnel if not eaten. Values are cherry 100, strawberry 200, orange 500, pretzel 700, apple 1,000, pear 2,000 and banana 5,000; from board 8 the fruit is random. Compare the original's fixed schedule in pacman fruit list.

Speed and difficulty

Ms. Pac-Man runs faster from the first board and ramps earlier, so new players lose lives sooner, but the randomness means that a lost life rarely comes from an unlearned pattern. Experts generally regard the original as the deeper competitive game and Ms. Pac-Man as the better casual game, which is why bars and restaurants kept Ms. Pac-Man cabinets for decades.

Scoring and records

Dots, pellets and ghost values are identical to the original, so the scoring logic in pacman point values table applies, with the fruit table above. Because the game is non-deterministic, there is no perfect score; the recognised record is 933,580 points, discussed in pacman world records.

Frequently asked questions

Who made Ms. Pac-Man?

General Computer Corporation created it as the Crazy Otto kit; Midway published it in 1982 under licence.

How many mazes does Ms. Pac-Man have?

Four, compared with one in the original.

Does Ms. Pac-Man have a kill screen?

Not a consistent one; the game becomes unstable around boards 134 to 142 depending on the cabinet.

Which is harder, Pac-Man or Ms. Pac-Man?

Ms. Pac-Man is faster and less predictable; the original is harder to play perfectly because perfection requires memorised patterns.

Is Clyde in Ms. Pac-Man?

No. The orange ghost is named Sue.
