This game has three modes of play; Adventure, Normal, and Versus. In all three modes, both players must line up blocks of a particular colour - and when three blocks have been lined up (vertically), they will crack. Once a fourth block of that same color lands on the three cracked ones, they will all shatter; for Adventure Mode, the object is to get the trapped sea creatures down to the bottom of the screen.
