3-D Ghostmania is a 3 dimensional version of Pacman...sort of. A major difference is that in order to kill a ghost, you must be physically standing on one of the power pellets, and let the ghosts run into you. When a ghost first sees you, it will start chasing you, and increasing it's point score (up to 255) while chasing you. You get as many points as it has accumulated when it runs into you standing on a pellet. Each pellet also has a count of how many ghost-killing charges it has left, starting at 3. It also re-generates the maze each time you play, based on a sequence of 11 digits that you can define at the bottom of the screen. It also features a demo mode, and a mode where you can just wander the maze without ghosts.
The publisher's of this game had something unique when you bought it: a monthly publication called The Challenge List, which listed high scores and competition events. When you bought the game, you got a free 6 month subscription. I have no idea how long this lasted, though.
