Lock 'n' Chase

The game's protagonist 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.

Lock 'n' Chase is a video game developed by Data East and released in arcades in Japan in 1981. It was licensed to Taito for distribution in North America. A maze game, Lock 'n' Chase was Data East's response to Pac-Man.

An updated version was published for the Game Boy in 1990 and later re-released on 3DS in 2011.
