Pac-Man’s four enemies – Blinky, Pinky, Inky, and Clyde – are not identical. Each ghost follows its own movement pattern, giving the game more strategy than it first appears. Blinky chases Pac-Man directly, Pinky tries to move ahead of him, Inky uses a combination of the others’ behaviors, and Clyde has a more unpredictable path. These differences ensure that the gameplay never feels repetitive.
