The game requires players to line up blocks in rows of three or more in order to allow their diver to delve deeper into the ocean. This occurs as they move blocks of various sizes (1 x 2, 2 x 1, or 2 x 2) horizontally into a column of coloured blocks. As players move blocks in from one side, they push blocks out of the other side. They can move these blocks up and down the column, as well as rotating their colours configuration, in order to create matches of coloured blocks within the column. As the diver progresses he will slowly begin to lose his air supply. The player has to refill the diver's air supply by clearing rows of blocks quicker or finding and clearing a row of three special blocks that will appear randomly as the game progresses. Darkness falls from the top of the screen as time goes on too, which makes it more difficult to make matches. There are two modes to select from in the game, Timed Dive and Free Dive. Timed Dive requires players to clear blocks until the diver reaches a certain depth before he runs out of air, at which point the level ends and the diver descends to the next stage. Free Dive is a never-ending puzzle mode that tests how deep the player's diver can go before he runs out of air. There is a relaxing Aquarium mode that when unlocked displays a virtual aquarium on the top screen.
