Jawbreaker II Cartridge

In Jawbreaker II, the player controls a large set of teeth that munches everything in sight. The screen is a series of rows of Dots and moving passages. The player's goal is to eat all the Dots without being hit by one of the Grinning Gobblers. There are Energizers on each level, which give the player power to eat the Grinning Gobblers. Each consecutive Grinning Gobbler is worth increasing points when eaten after a single Energizer. A level is cleared when all the Dots and Energizers are eaten.

A 1-player arcade game of sudden danger and narrow escapes. You control the Jawbreaker, a powerful set of crunchers. Race through 5 shifting mazes before your power runs out - raising your score by devouring Dots and Special Treats, evading Grinning Gobblers, and munching Energizers. (Joysticks recommended.)



Jawbreaker is a thrilling one-player game of narrow escapes and sudden danger. You control the Jawbreaker, a powerful set of teeth, and race through a maze of shifting walls and doors. Y our score climbs as you clear each screen by devouring Dots and Special Treats. A toothbrush cleans your teeth to get you ready for more action. Avoid the Grinning Gobblers as they come at you from either side. Eating Energizers gives you the power to chase and destroy the Gobblers. Watch out-your power is only temporary. Soon the Grinning Gobblers will turn and attack!
