Scoring

Each game is played to 21 points, with players scoring a point whenever they win a rally regardless of whether they served (this differs from the old system where players could only win a point on their serve and each game was played to 15 points). A match is the best of three games

If the score ties at 20–20, then the game continues until one side gains a two-point lead (such as 24–22), except when there is a tie at 29–29, in which the game goes to a golden point of 30. Whoever scores this point wins the game

At the start of a match, the shuttlecock is cast and the side towards which the shuttlecock is pointing serves first. Alternatively, a coin may be tossed, with the winners choosing whether to serve or receive first, or choosing which end of the court to occupy first, and their opponents making the leftover the remaining choice

In subsequent games, the winners of the previous game serve first. Matches are best out of three: a player or pair must win two games (of 21 points each) to win the match. For the first rally of any doubles game, the serving pair may decide who serves and the receiving pair may decide who receives. The players change ends at the start of the second game; if the match reaches a third game, they change ends both at the start of the game and when the leading player's or pair's score reaches 11 points.
