- Choose Match: the best of three games, or one game of 21 points if that was agreed before the match.
- Type the names of the two players, or keep Player 1 and Player 2.
- Press Point for the side that won each rally. The score of each game is counted for you.
- Use Undo last point to take back a mistake, and New match to start again.
How a game is won
Under rally point scoring the side that wins a rally adds a point, whether it served or received (Law 7). A game is won at 21 points, but only with a lead of two points: at 20-all the side that first gets two points ahead wins the game. At 29-all the side that scores the 30th point wins, so a game never goes past 30 points.
Game: first to 21 points with a lead of 2, or the 30th point (at 29-all)
Match: best of three games, two games to win (unless another arrangement is made)The match, and what this counter does not cover
A match is the best of three games, unless another arrangement is made (Law 7.1). The BWF Statutes, in Part II, Section 1B, Appendix 3, allow other systems by prior arrangement; one game of 21 points is one of them, and the counter offers it. The other systems in that appendix are not in this counter.
- Changes of ends (Law 8) and intervals between games and at 11 points (Law 16.2) are not shown.
- The BWF has adopted a new 3 x 15 system, to take effect on 4 January 2027. Until then the 2025 Laws apply; this counter follows Law 7 as printed in the 2021 edition.
Example: three games, won two games to one
Player 1 wins the first game 21-19: the score reaches 19-19, then Player 1 wins two rallies, 20-19 and 21-19, which is a lead of two. Player 2 wins the second game, 21-0, written 0-21. Player 1 wins the third game 21-0 and takes the match two games to one.
| Game | Score | Winner |
|---|---|---|
| Game 1 | 21-19 | Player 1 |
| Game 2 | 0-21 | Player 2 |
| Game 3 | 21-0 | Player 1 |
Frequently asked questions
Does the counter store the score?
No. Nothing is stored or sent to us. The score lives in the page, and it starts again from zero when you reload the page or leave it.
Why does a game go past 21 points?
A game is won at 21 only with a lead of two points. At 20-all the game goes on until one side is two points ahead, and at 29-all the 30th point wins, so a game can end at 30 points but never after it (Law 7).
What happens at 29-29?
The side that scores the 30th point wins the game (Law 7). In this counter the game ends as soon as one side reaches 30 points.
When should I choose one game of 21 points?
Choose it only when the match was agreed beforehand as one game. The Laws allow this by prior arrangement (Part II, Section 1B, Appendix 3); otherwise the match is the best of three games.
Will the scoring change?
The BWF has adopted a new 3 x 15 scoring system, which takes effect on 4 January 2027. Until then the 2025 Laws apply. Check the edition in force before you use the counter for an official match.
Is this the official score of a match?
No. The counter follows the Laws for the score, but the official score is kept by the umpire and the tournament organisers.
