The Ghosts Follow Different Rules
Pac-Man’s ghosts can look like four pursuers improvising in a maze, but their movement is governed by distinct rules. Blinky, the red ghost, aims at Pac-Man’s current tile. Pinky, the pink ghost, aims several tiles ahead, making him seem to anticipate a turn. Inky’s target depends on both Pac-Man’s position and Blinky’s, while Clyde changes between chasing and heading toward his corner depending on how close he is.
These are not simply four versions of “follow the player.” The target-tile rules give each ghost a recognizable character while keeping the game’s movement predictable enough to learn.
A Demonstration Hiding in Plain Sight
In attract mode—the cabinet’s display while no one is playing—the game runs without a player’s input. Its gameplay demonstrations let a patient watcher see the ghosts navigate the maze and respond to Pac-Man. The screen does not spell out their code, but repeated encounters offer clues: one ghost closes in, another appears to cut off a route, and others behave differently as the chase unfolds.
That makes watching useful. Once players noticed the patterns, they could stop treating every pursuit as arbitrary and begin choosing routes with a ghost’s likely target in mind. The cabinet showed the behavior; understanding the rules took observation.
Predictable, Not Mindless
The ghosts’ behavior also changes with the game’s chase and scatter phases: they alternate between pursuing Pac-Man and heading toward designated corners. Their decisions are rule-based, but what a player sees depends on position, timing, and the current phase. That combination makes their movements feel lively without requiring them to think like human opponents.
So the attract display was more than decoration. It offered a free preview of the system players would soon have to read under pressure—and a reminder that, in Pac-Man, learning where a ghost is trying to go can matter more than simply watching where it is.
