The Pac-Man game is an electronic maze-chase arcade game. Players use a joystick to navigate the maze whereby the central character, the “gobbler” maze-chaser, consumes pink dots. The game ends when a monster catches the gobbler. Similar to the Pac-Man game, defendant’s Packri Monster is played using a joystick, whereby the player moves a character through the maze. The Packri Monster gives the illusion of the monster eating the dots in a manner resembling the monster in Pac-Man.
