In this puzzle game, different combinations of blocks mixed with Cosmo Gang members fall from the top to the bottom of the screen. The object is to stack up the blocks to form a complete row causing that row to disappear. To accomplish this a ball must be used to eliminate the Cosmo Gang that stacked up to block your progress.
