DESCRIPTION

This 1990 puzzle game from Sega of America Inc. requires quick thoughts and quick actions. You control columns of gems four pieces long as they steadily fall towards the bottom of the screen. One button cycles the order of the gems, and the joystick moves the columns left or right. The object of the game is to clear away as many gems as possible and to score points along the way. In a two player contest you attempt to bury the other player first by clearing more gems faster. You clear gems away by lining up three gems of the same color in a row. Bonus points are awarded for clearing more than one line simultaneously. As the levels progress, the gems move faster and faster. ~ Jeff Irwin, All Game Guide
