A badminton match consists of sets, and each set is played to 21 points. The player or pair that scores 21 points first wins the set. If the score reaches 20-20, the set is won by the first player or pair to achieve a two-point advantage. If the score reaches 29-29, the player or pair scoring the 30th point wins.

The right to serve alternates between the players or pairs after each point is scored. The serve is made from the right service court when the server's score is even and from the left T0=service court when the server's score is odd. The serve must be hit below the server's waist and diagonally across the net into the opponent's service court.

Serving or receiving from the wrong service court.

Failing to hit the shuttlecock over the net or into the opponent's court.

Letting the shuttlecock touch the ground within the court boundaries.

Hitting the shuttlecock twice in succession.

Touching the net with the racket or body.

Obstructing the opponent's shot.

In doubles, the service rotates between the two players on the serving side. When the serving side wins a rally, the server moves to the opposite service court, and the partner takes over the serve.

During play, if the shuttlecock lands on the boundary lines, it is considered in. If it lands outside the boundary lines or touches the ground outside the court, it is considered out.

A let is called if a rally needs to be stopped and replayed due to external interference or if the shuttlecock hits the net and lands in the opponent's court.

The match is won by the player or pair that wins the predetermined number of sets. In most tournaments, it's the best of three sets.
