The gameplay of Tekken 6 runs along the same lines as previous Tekkens. Players start by picking their character, who they will use throughout the King of Iron Fist tournament. In each round of the tournament, the first combatant to reach two K.O.'s is declared winner, although this can be extended to five. If neither player is victorious by the time the round timer reaches zero, whoever has the most health will be declared the winner.
