Doubles:
In the game, there are two players on each side. After having been decided which side is to deliver the service first, the player in the right hand service court of that side shall start the game. He shall serve to the opposing player in the right service court. This matter is decided by the toss winners, and the other matters by the losing one. It is decided before hand whether the game shall have 15 points or 21.
If the opponent returns the shuttle before it touches the ground to the player who started the game, he shall again return it to the latter.

Now the player doing the service shall be in the left hand service court and shall serve to the player of the opposing team in the left hand service court.
