The game's main character is a thief. The object of the game is to enter a maze and collect all the coins and, if possible, any other treasure that may appear. The thief must then exit the maze (a vault) without being apprehended by the Super D (policemen). The thief can close doorways within the maze in order to temporarily trap the Super D and allow him to keep his distance from them. Only two doors can be closed at a time. The Super D policemen are named Stiffy, Scaredy, Smarty, and Silly.
