Badminton is a racquet sport played using racquets to hit a
shuttlecock across a net. Although it may be played with larger teams,
the most common forms of the game are "singles" and "doubles".
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 racquet and landing it
within the other team's half of the court. Each side may only strike
the shuttlecock once before it passes over the net. Play ends once the
shuttlecock has struck the floor or ground, or if a fault has been
called by the umpire, service judge, or the opposing side.
