21-Point Badminton Rules Explained
Badminton uses 21-point rally scoring, win by 2, with a cap at 30. Best of 3 games per match. The serving rotation in doubles is the trickiest part of any racquet sport — server, receiver, and court position all rotate based on the score.

How badminton scoring works
A badminton game is first to 21 points with a 2-point margin. There is a cap at 30 — if the score reaches 29-29, the next point wins the game (no more win-by-2 from there).
Rally scoring means every rally produces a point — there's no concept of a "side-out" where you fail to score on a non-serve rally. This was changed in 2006 (the old format used 15-point side-out scoring).
Matches are best of 3 games — first to 2 game wins takes the match.
Edge cases and details
There used to be a "service over" concept in old badminton scoring — you couldn't score if you didn't serve. That's gone since 2006. Every rally scores now.
The "service court" in doubles is determined by the server's score: serve from the right court when the score is even, left court when odd. The receiver stands diagonally across.
Service faults include foot faults, the shuttle going below the waist on contact, and the racquet head being above the hand at contact. Strict on paper but rare in practice.
Volley handles this automatically
Volley scores badminton with proper 21-point rally scoring, the 30-point cap, and full doubles serving rotation tracked automatically — even when the score gets weird at 29-29.
Pick the format at match setup, name your sides, and tap to score. Volley applies the rules from there — you don't have to remember any of the edge cases.

Can I track my Badminton ELO rating?
Yes. Volley tracks your Badminton ELO across every match you score in the app. Each sport has its own rating, so beating someone in Badminton doesn't change your rating in any other sport you play.

Yes. Volley supports single elimination, round robin, and pool play formats — pick the one that fits your time and player count. Free generators are also available on the website if you don't want every player on the app.
