Volleyball is a team sport.
Volleyball . But simply , play 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 receiving team must not let the ball be grounded within their court . The team that wins the rally is awarded a point , and serves the ball to start the next rally .
