The BBL Championship is the flagship competition of the British Basketball League and features all member teams playing a 33-game regular season, from September to April. Matches are played according to FIBA rules and games consist of four-quarters of 10 minutes each. Two points are awarded for a win, with overtime used if the score is tied at the final buzzer – unlimited numbers of 5-minute overtime periods are played until one team is ahead when a period ends.
