The complete set of rules is extensive, but play essentially proceeds as follows: a player on one of the teams begins a 'rally' by serving the ball (tossing or releasing it and then hitting it with a hand or arm), from behind the back boundary line of the court, over the net, and into the receiving team's court. The adapted version of volleyball at the Summer Paralympic Games is sitting volleyball. Beach volleyball was introduced to the programme at the Atlanta 1996 Summer Olympics. It has been a part of the official program of the Summer Olympic Games since Tokyo 1964. Each team tries to score points by grounding a ball on the other team's court under organized rules. Volleyball is a team sport in which two teams of six players are separated by a net. 1895, Holyoke, Massachusetts, United States
