Under the BWF Laws of Badminton, a match is best of three games to 21, with rally scoring: every rally scores a point. At 20–all a game must be won by two, and at 29–all the side that reaches 30 wins it.
League standings rank on matches won, then games won and lost, then points. Club team matches are made of several rubbers — singles, doubles, mixed — and the team table counts rubbers won as well as match results.
