Kawasaki Jet Ski is a racing game set in the world of jet-skiing. The goal is to beat your opponents by navigating your jet-ski through challenging courses marked by colored buoys. Red and yellow buoys must be passed on the right and left sides, respectively, to gain speed and an advantage in the race. Failing to pass these buoys will slow you down and eventually disqualify you.
The game features several modes, including Warm Up, a training session in a course called Dolphin Park; Time Trials, where you race against time; Championship, where you compete in a tournament with four different difficulty levels; and Stunt Mode, which awards points for performing various stunts. A two-player split-screen versus mode is also available. You can customize your jet-ski rider, adjusting parameters such as grip, handling, acceleration, top speed, and collision stability.
