How to play badminton？
The Laws of Badminton and Competition Regulations in the BWF Statutes provide the detail on every aspect of the game of badminton.
Below is a brief overview - simplified badminton rules.
Scoring System
| - |
A match consists of the best of 3 games of 21 points.
|
| - |
Every time there is a serve – there is a point scored.
|
| - |
The side winning a rally adds a point to its score.
|
| - |
At 20 all, the side which gains a 2 point lead first, wins that game.
|
| - |
At 29 all, the side scoring the 30th point, wins that game.
|
| - |
The side winning a game serves first in the next game.
|
Interval and Change of Ends
| - |
When the leading score reaches 11 points, players have a 60 second interval.
|
| - |
A 2 minute interval between each game is allowed.
|
| - |
In the third game, players change ends when the leading score reaches 11 points.
|
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.
