Grouping Ghosts in Ms. Pac-Man

Ms. Pac-Man. Currently on the outs with Pac-Man rights-owner Bandai-Namco because its origins weren’t with them, and its developer GCC licensed the rights to another party than them, which has given us such travesties as “Pac-Mom.” Which is a shame, because in general Ms. Pac-Man is a better game than Pac-Man. Its four mazes don’t have the nuance that Pac-Man’s does (there’s no one-way routes, for instance), it doesn’t have scatter periods to give the player a breather during each board, and after board #7 its fruit, and the score award for chasing it down, is random, taking an important measure of skill and just throwing it up in the air and shrugging.

But it does have multiple mazes. And its Red and Pink ghosts behave randomly for the first bit of each board (here’s a prior post about that), eliminating the major design flaw of Pac-Man: its vulnerability to patterns. Pac-Man is certainly not the only game to lack substantive randomness, but the nature of its maze-based play is that it’s relatively easy to perform them. So long as you hold in the direction you need to go at least five frames before you reach an intersection, you can be sure that you’re performing a pattern perfectly, making Pac-Man into an endurance game more than anything. Ms. Pac-Man doesn’t have that problem.

But that doesn’t mean that Ms. Pac-Man can’t be mastered, and the basis of that is through a technique called grouping. Grouping can be done in Pac-Man too, but if you know some good patterns it isn’t necessary. But in Ms. Pac-Man it’s a key skill, both to make sure you eat as many ghosts as possible in the early and mid boards, and for general survival, for a bunch of ghosts in one lump is much easier to avoid than a scattered mess of four separate ghosts.

David Manning’s introductory video on grouping ghosts in Ms. Pac-Man (20m) is ten years old, but it’s still an invaluable aid for players seeking to master that game.

The basic idea is to understand the ways to move in the maze so that pursuing ghosts take slightly different routes to reach you, so that leading ghosts are delayed just a bit, or trailing ghosts approach you slightly faster.

This time I’m going to leave the explanation to the video, but it’s interesting to think about, and to see if you can apply this information yourself.
