Badminton is played using strung rackets (similar to tennis rackets, but smaller, more flexible and much lighter) and a feathered shuttlecock by either two or four players on a marked rectangular court. It can be played indoors or outdoors, although games normally take place in a draft-free indoor environment. The object of the game is to score points by hitting the shuttlecock over the net into the opponent’s half of the court, so that it hits the ground before they are able to return it.
