Wave Rush is a water-based arcade racing game. You control a single boat, racing against three opponents. The first to reach the finish line wins.
Each race lasts exactly three minutes. Obstacles appear along the route: colliding with them or with opponents damages your boat and reduces speed. To repair the boat, you must collect a lifebuoy. After every collision, you need to accelerate again from reduced speed.
Collecting a turtle grants a temporary speed boost.

On-screen displays include:
— a timer (exactly 3 minutes per race),
— the damage status of opponents’ boats.

Not all boats reach the finish — those with critical damage are eliminated early.
New locations unlock with each completed level, and achievements are awarded progressively.
