Rules of the Game (as provided by Badminton Canada):
Rally Point Scoring System
- A match consists of the best of 3 games of 21 points.

- 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

- If the receiving side wins a rally, the receiving side scores a point. The receiving side becomes the new serving side.
