The game revolves around the concept of watercraft racing. Contestants race along in an aquatic track with a sort of obstacles and speed boosters as boost ramps, while they drive motorized rafts. Players must drive on their rafts, and come to the finish line at first place to win. Also, players have to avoid such obstacles as buoys and also take some ramps to gain a boost of speed momentarily. When playing in Score Scuffle, the minigame ends once all players cross the finish. If five minutes pass without anyone reaching the finish line or if both players come to the finish line at the same time in the Duel variant, it will be considered a tie.
If both players get the same score in the Duel variant that breaks the current record, it counts as a new record even though no one won, as it will say "Tie" after the "New Record" fanfare. This also applies to the other Duel minigames with a record system.
