Beach volleyball follows the basic rules of indoor volleyball, but with a few adjustments. The first of these is the number of players: there are only two on each side. The other is the number of points needed to complete a set: twenty-one in beach volleyball and twenty-five in indoor volleyball.
A match is the the best of three sets. In other words, to win a game, it is necessary to win two sets. The tie-breaker is the same, and the winner is the first one to score twenty-one points.
The objective of beach volleyball is the same as that of indoor volleyball, to make the ball touch the ground on the opponent’s side, but in order to score a valid point, the ball must pass between the two antennas positioned at the ends of the net.
