Other scoring systems have also been used in various locations, including the five-point must system (in which the winning fighter is awarded five points, the loser four or fewer), the one-point system (in which the winning fighter is awarded one or more points, and the losing fighter is awarded zero), and the rounds system which simply awards the round to the winning fighter. In the rounds system, the bout is won by the fighter determined to have won more rounds. This system often used a supplemental points system (generally the ten-point must) in the case of even rounds.
