World Series of Boxing Like professional boxing, each bout is decided by the scores of three judges or, in some cases, by a knockout, technical knockout or walk-over. A WSB meet between two international franchises consists of bouts in ten (formerly five) weight categories. There are five three-minute rounds in each bout and the team that wins the most number of bouts wins the meet.
