Beach volleyball is a team sport played by two teams of two players on a sand court divided by a net. As in indoor volleyball, the objective of the game is to send the ball over the net and to ground it on the opponent's side of the court, and to prevent the same effort by the opponent. A team is allowed up to three touches to return the ball across the net, and individual players may not touch the ball twice consecutively except after making a block touch (the block touch counting as one touch, leaving only two more touches before the ball must be hit over). The ball is put in play with a serve—a hit by the server from behind the rear court boundary over the net to the opponents. The rally continues until the ball is grounded on the playing court, goes "out", or a fault is made in the attempt to return the ball. The team that wins the rally scores a point and serves to start the following rally. The four players serve in the same sequence throughout the match, changing server each time a rally is won by the receiving team.
