Toss :
The rules of badminton states that a toss shall be conducted before a game starts. If you win, you can choose between serving first or to start play at either end of the court. Your opponent can then exercise the remaining choice.
Scoring system :
The rules of badminton states that a badminton match shall consist of the best of 3 games. In doubles and men's singles, the first side to score 15 points wins the game. In women's singles, the first side to score 11 points wins the game.
If the score becomes 14-all (10-all in women's singles), the side which first scored 14 (10) shall exercise the choice to continue the game to 15 (11) points or to 'set' the game to 17 (13) points.
The side winning a game serves first in the next game. Only the serving side can add a point to its score.
Recently BWF have been testing a new scoring format of 21 points per game on all major Badminton competition and decided to replace the old format permanently.
Badminton is a racquet sport played by either two opposing players (singles) or two opposing pairs (doubles), who take positions on opposite halves of a rectangular court that is divided by a net. Players score points by striking a shuttlecock with their racquet so that it passes over the net and lands in their opponents' half of the court. Each side may only strike the shuttlecock once before it passes over the net. A rally ends once the shuttlecock has struck the floor.
