Badminton is a request sport played using requests to hit a shuttlecock across a net. Although it may be played with larger teams, the most common forms of the game are "singles" (with one player per side) and "doubles" (with two players per side). Badminton is often played as a casual outdoor activity in a yard or on a beach; formal games are played on a rectangular indoor court. Points are scored by striking the shuttlecock with the request and landing it within the opposing side's half of the court. Each side may only strike the shuttlecock once before it passes over the net.
