What really helps is knowing the pattern of the game. Once you try a few routes/techniques/strategies or whatever or have just been playing the game long enough, you'll understand certain ways that the ghosts follow or when they chase Pac-Man and which direction they will follow Pac-Man. This helps so you can minimise the amount of time it takes for the ghosts to chase Pac-Man in the way you want. (Any expansion or new guide wanted, lemme know)
