Lock ‘n’ Chase, a maze game released in response to Pac-Man, was published by Mattel for the Atari 2600 in 1982. Players control a thief whose objective is to enter a maze, collect all the coins, and any other treasures that may appear, before exiting the maze (a vault) without being caught by the Super D policemen. The thief can shut doors within the maze to temporarily trap the Super D and maintain distance. However, only two doors can be closed at once. The Super D policemen have names like Stiffy, Scaredy, Smarty, and Silly.
Each coin, represented as a dot, is worth 20 points. In every level, money bags randomly materialize in the maze’s center, with values ranging from 500 to 4,000 points. Each level also features a unique treasure located near the maze’s center, similar to Pac-Man’s food items. The treasures include a top hat, crown, briefcase, and telephone, with the first three valued at 200, 300, and 500 points, respectively. As players progress through levels, additional treasures and their point values are revealed.
