I'm interested in a new sport called sand volleyball. Can you tell me more about it?

Sand volleyball is played on an outdoor beach or indoor court with a hard-packed sand surface. It is similar to traditional volleyball, but the players are allowed to use their feet and hands to hit the ball instead of only their arms. The game is typically played by two teams of six players each, who take turns serving and passing the ball back and forth across the net. Each team tries to score points by sending the ball over the opponent's side of the net. The first team to reach 21 points wins.
