Badminton is a sport for two or four people. The game is either one player against one player or a team of two players against another team of two players. Players use rackets to hit a shuttlecock over a net. The aim of the game is to hit the shuttlecock over the net in a way that the other player or pair cannot hit it back properly before it hits the floor. Every time this is done, the player or pair gets one point. They also get to serve. The first player or pair to reach 21 points wins a game. The winner of the match is the first to win 2 sets.
