Beach volleyball is an Olympic team sport played on sand. Two teams, positioned on either side of a net which divides a rectangular court, hit a volleyball, usually using the hands or arms. Players on each team attempt to hit the ball over the net in such a way that it touches the ground inside the court boundaries, and to prevent the ball from touching the ground on their own side of the court. Beach volleyball is a popular recreational activity on many beaches around the world, and is generally most popular in areas with wide sandy beaches; however, it is also frequently played on inland sand courts, and has become quite popular in some land-locked countries, notably Switzerland. Though the official rules call for two players per team, recreational (non-competitive) games often have more players.
Beach volleyball evolved from indoor volleyball, and the two sports remain very similar: a team scores points by grounding the ball on the opponents' court, or when the opposing team commits a fault (error or illegal action); teams can contact the ball no more than three times before the ball crosses the net; and consecutive contacts must be made by different players. The most important differences between beach and indoor volleyball are the playing surface (deep sand rather than a hard floor), and the team size (two players per team rather than six). There are many minor differences as well, including:
