From the inlay Four Chasers Choice of 15 Mazes Multiple Skill Levels Sound Effects Demo Mode Laser Defence Fully Machine Coded User Summary Heavily inspired by Namco's Pac-Man, Gulpman follows the same basic formula. However unlike the original, it includes 15 different mazes. Also, instead of eating the 'chasers' the player has a limited number of lasers which blast in four different directions. If a chaser is hit, it is sent back to one of the four corners of the screen.
