A card game of martial arts combat. The game uses a custom deck containing fifty-six cards, with eight cards for each of seven different types: Punch, Kick, Block, Grab, Move, Zen, and Combo.

The players must roll fighter characters before play. Each fighter has ten hit points and rolls ten times on a series of Maneuver Tables. This results in a list of "moves" the fighter knows and some die roll results can add hit points. Each Maneuver is rated for a cost in cards that must be played to use the move and for damage caused by the move (Attack Maneuvers) or damage negated (Defense Maneuvers).

The object of the game is to reduce your opponent to zero hit points.
