Jamey Pittman is the creator of the foremost document on the workings of Pac-Man ever created, the Pac-Man Dossier. If you’ve never read it, but have any interest in playing classic Pac-Man, then you should go read it immediately. It will make so many things make sense to you.
Pac-Man has a reputation as a game of patterns, and seems designed in such a way as to enable patterns to work. The only randomness is in the behavior of the ghosts when they’re vulnerable, and even then, if the player has performed the same moves at the time times up to that point in the level, even their vulnerable behavior will be consistent. Its GCC-developed follow-up, Ms. Pac-Man, has the red and pink ghosts move randomly at the start of each board specifically to foil patterns.
But you don’t have to play Pac-Man as a pattern game. It is possible to play it “freestyle,” like a naive player would, reacting to the ghosts’ movements. You’re unlikely to make it to Pac-Man’s famous kill screen at board 256 that way, but you can still make it pretty far.
Key to doing that is keeping the ghosts as close to each other as you can. The ghosts are much more dangerous when they’re scattered around you, because they can block off all of your escape routes. Four ghosts piled up on the same spot not only can’t block off other corridors, but their AIs tend to continue to keep them together, at least when they’re far away from Pac-Man. Red and Orange behave identically when they’re at a distance, and Pink’s behavior appear to be more like Red’s the further away from Pac-Man it us. Blue has the most chance of diverging, but often moves the same way anyway.
Not only does keeping the ghosts clustered make survival easier, but it makes it much easier to eat all of them with a single Energizer. The ghosts only turn blue up to around the 4th Key board, but up to that point it’s basically impossible to get the maximum score from every Energizer if one hasn’t managed to herd the ghosts into a single, easy-to-manage blob.
That’s where Jamey’s tutorial comes through. It presents a series of situations and techniques for getting the ghosts near each other and moving as one unit, whether it’s for avoiding them or getting the maximum points from an Energizer. It’s a bit much for casual play, but it can be very interesting to see how a true expert goes about doing it. Here, then, is the tutorial (27 minutes):
