"Pac-Man" is a maze chase video game; the player controls the eponymous character through an enclosed maze. The objective of the game is to eat all of the dots placed in the maze while avoiding four colored ghosts — Blinky (red), Pinky (pink), Inky (cyan), and Clyde (orange) — that pursue him. When all of the dots are eaten, the player advances to the next level. If Pac-Man makes contact with a ghost, he will lose a life; the game ends when all lives are lost. Each of the four ghosts have their own unique, distinct artificial intelligence (A.I.), or "personalities"; Blinky gives direct chase to Pac-Man, Pinky and Inky try to position themselves in front of Pac-Man, usually by cornering him, and Clyde will switch between chasing Pac-Man and fleeing from him.
