Sai Combat is an ancient oriental martial art in which the Sai weapon is used to deliver blows and block an opposing fighter's moves, as well as the more familiar karate kicks and blows. It also exists as a form of Japanese aerobics called Sai Kata, involving increasingly intricate moves with the Sai and practised as a solo art. Sai Karate originated in Okinawa many centuries ago, spreading gradually throughout the Japanese islands.

Work your way up through eight levels from white belt to black belt, and then through the eight Dan levels to become a Sai Master. You score 100, 200 or 300 points for each successful blow landed on your opponent, depending on the type of blow. A minimum of 600 points are required for a knockdown fall. Your Chi (energy) levels are shown on the dragon's head in the scoreboard.

In the one player option, three falls are required to move on to the next level.
