In the game, the player rides along on an inner tube, towed by a motorboat, and has to go through the various levels. The inner tube follows the mouse in an arc, based on its horizontal position, and the player can jump by pressing the left mouse button.
In each level, a series of obstacles appear on the screen, and the player must avoid them. Running into an obstacle tips the player over, and the player loses a life, from a total of 3. Starting level 2, the player may gain another life by collecting white life rings, but may never have more than 3 lives left. The game ends by being tipped over without having lives left.
Whenever the player dodges an item, they receive 1 point, or 10 points if they jump over the obstacle; the only exception being gray buoys, which will tip the player over anyway if they try to jump over it. In the end of the game, the player earns a coins for every 10 points from the total score, rounded to the nearest multiple of 10.
