The Service

The server and the receiver stand in diagonally opposite courts. The service must be delivered underhand from beneath the server's waist, and the server must have part of the both feet on the floor. Service alternates from the right and left halves of the court, beginning from the right in every game. Players change ends after each of the first two games and midway through the third game.

The Scoring System

Matches are the best of three games. if the server wins a rally, he or she scores a point and serves again from the other service court. if the serving player loses the rally, the opposing player or  team scores a point. In badminton, 21 points win a game unless the scores reaches 20-20. In that case, the first player to gain a 2 point advantage wins. If the score reaches 29-29, the winner is the first player to get 30.

Scoring Points

A point is won by hitting the shuttle over the net so that it lands on the court before the opponent can return it or so that the opponent makes an error in returning it.

A point is lost if

• the shuttle is hit in to or under the net
• it lands outside the opponent's court
• the shuttle touches a players clothing
• a player hits the shuttle before it crosses the net
