Beach Volleyball is a sport played by two teams of two players each on a sand court divided by a net. The ball is played by hitting it with any part of the body. The objective of the game is for each team to send the ball over the net to ground it on the opponent's court, and to prevent the ball from being grounded on its own court. The ball is put into play by the serving player. The player serves by hitting the ball, with one hand or arm, over the net to the opponent's court. A team is entitled to hit the ball three times to return it to the opponent's court. A player is not allowed to hit the ball twice consecutively (except at blocking and at the first contact). The rally continues until the ball touches the ground, goes "out", or a team fails to return it properly. Regardless which team is serving, the teams that wins a rally scores a point gaining also the right to serve. This is called “Rally Point System”. The serving player must be alternated every time a team regains the right to serve. Matches are played in the “best two of three set” format. The first team to win two sets wins the match. The first two sets are played to 21 points, and the 3rd set if needed is played to 15 points. For all sets a 2 point advantage is required, with no cap.
