Each die is filled with monsters which hatch out and the player must shoot to shrink, then collect them. If the player does not collect each shrunken monster quickly, it turns into a time-eating bug which flies to the time limit bar and consumes a chunk of it. If you touch one monster or run out of time then you lose a life. The game ends if all lives are lost. There are 50 distinct levels, called "rounds" in the game, even though the counter goes to 99. The player can play through the levels loops infinitely, with no apparent end. There are also "bonus rounds" every so often where the player can shoot colored dice to reveal prizes and increase his or her score.
