Badminton 21 points

In week 3, i learn and understand the rules and scoring system of a badminton game.

Scoring System

Each game is played with 21 points, with players scoring a point whenever they win a rally (this differs from the old system, where players could only win a point on their serve). A match is the best of three games.

At the start of the rally, the server and receiver stand in diagonally opposite service courts (see court dimensions). The server hits the shuttlecock so that it would land in the receiver's service court. This is similar to tennis, except that a badminton serve must be hit below shoulder height and with the racquet head below the servers wrist, the shuttlecock is not allowed to bounce and in badminton, the players stand inside their service courts unlike tennis.

When the serving side loses a rally, the serve passes to their opponent(s) (unlike the old system, there is no "second serve" in doubles).

In singles, the server stands in his right service court when his score is even, and in his left service court when his score is odd.

In doubles, if the serving side wins a rally, the same player continues to serve, but he changes service courts so that he serves to each opponent in turn. If the opponents win the rally and their new score is even, the player in the right service court serves; if odd, the player in the left service court serves. The players' service courts are determined by their positions at the start of the previous rally, not by where they were standing at the end of the rally. A consequence of this system is that, each time a side regains the service, the server will be the player who did not serve last time.
