A platform game with players race to reach the top of each level by jumping on platforms. Players can fire rainbows to kill enemies or to stand upon. Bonus points are scored by collecting the items dotted around the level and the bonuses left by killing enemies.
Kill enemies by hitting them with rainbows or by crushing rainbows on their head. There are seven levels each with four rounds. Holding down the jump button will allow you to jump onto rainbows without crushing them.
