Race three rivals to the surface.
Drag left or right to steer (arrow keys on a computer). Dodge rocks, jellyfish, nets, seaweed and patrolling sharks, and don't slow down, because a hungry shark is chasing you. Shoot bubbles to knock rivals back, pop jellyfish and cut nets. Ride currents and grab bubbles to fill your boost. On a computer: arrows steer, space shoots, up arrow boosts. Finish in the top 3 to unlock the next level. There are 70 levels across 7 worlds, and winning races unlocks more fish.
