Badminton's rules

Singles At the beginning of the game (0-0) and when the server’s score is even, the server serves from the right service court. When the server’s score is odd, the server serves from the left service court. If the server wins a rally, the server scores a point and then serves again from the alternate service court. If the receiver wins a rally, the receiver scores a point and becomes the new server. They serve from the appropriate service court – left if their score is odd, and right if it is even. Doubles A side has only one ‘service’. The service passes consecutively to the players as shown in the diagram. At the beginning of the game and when the score is even, the server serves from the right service court. When it is odd, the server serves from the left court. If the serving side wins a rally, the serving side scores a point and the same server serves again from the alternate service court. If the receiving side wins a rally, the receiving side scores a point. The receiving side becomes the new serving side. The players do not change their respective service courts until they win a point when their side is serving.
