Jawbreaker is a video game programmed by John Harris and released in 1981 for the Atari 400/800 by On-line Systems.[1] It is essentially a Pac-Man clone, in that a small yellow set of jaws is moved around the map to pick up small dots while avoiding the "jawbreakers" which roll around the map. If the jaws bite the jawbreaker, they will be destroyed and the player will lose a life. It was released for the Atari 2600 and later the Apple II.


John Harris also developed and released ports of the game for the Atari 2600 under Tigervision (1982), and the Apple II (1981) under On-Line Systems. A game by the same name for the Commodore 64 was released in 1983, but coded by Doug Whittaker and Chuck Bueche and bore little resemblance to the original version.[2]


In 1983 Softline readers named Jawbreaker second on its Top Thirty list of Atari 8-bit programs by popularity, behind only Star Raiders.[3] The magazine called the game "a very clean, fast-action game with little sophistication", citing its "clean, fast, and cheerful" graphics and consistent gameplay across platforms, including the Atari 2600.[4]


In 1981 Atari, which licensed the home rights to Pac-Man, unsuccessfully sought an injunction against the sale of Jawbreaker and Gobbler, another On-Line computer game, which Atari claimed unduly resembled Pac-Man. On-Line's Ken Williams denied Atari's claim but was uncertain of the outcome, stating "If this opens the door to other programmers ripping off my software, what happened here was a bad thing".[5]

A sequel entitled Jawbreaker II was released in 1983 on the Atari 400/800, Apple II, and Texas Instruments TI99/4A. These ports were not coded by John Harris, and were instead contracted to Dan Drew.[1][6]
