What are the jobs of the 4 ghost in Pac Man?

In Pac-Man, the four ghosts—Blinky, Pinky, Inky, and Clyde—each have distinct behaviors. Blinky (red) chases Pac-Man directly, while Pinky (pink) tries to position herself in front of him. Inky (cyan) has a more unpredictable strategy that combines elements of both Blinky's and Pinky's tactics, and Clyde (orange) alternates between chasing Pac-Man and retreating to a corner. Together, they create a dynamic challenge for players as they navigate the maze.
