Like the original Pac-Man, the basic game play of Pac-Man Championship Edition consists entirely of navigating Pac-Man through a maze, eating dots, power pellets and bonus items, and avoiding the four ghosts that roam the maze as well. If Pac-Man is caught by a ghost, the player loses a life. Eating a power pellet causes the ghosts to turn blue, allowing Pac-Man to eat them and send them back to their home, where they re-emerge in their original form. (wikipedia.org)
