The same concept as the game "Snake": You have a square cursor that moves around the screen with a tail on it, and you try not to run into the screen border or your tail. With the 2-player option, you can try to block and trap your opponent with your tail. Game levels 13-14 are called "Video Graffiti" and allow you to draw or write on your TV screen, without any game objective. Simple colors and sounds--a very rudimentary home videogame. A. Cullum
