Make an illegal sustition. Strike the ball while supported by another player or object. If team A causes the ball to hit the ceiling or object above their playing court and the ball comes down on their side of the net, play may continue, provided it was not an illegal hit or the third hit. A back row player may move up to the front of the court to play a ball which is below the level of the top of the net. Both feet must be outside of the rear white line while the player is serving and the ball must clear the net on the service.
Service area is six feet deep and extends inward ten feet from the right side line.
A ball may be played three times on one side provided that the same player does not touch thye ball twice in succession. A player who is touched by the ball above and including the waist shall be considered as playing the ball. If the ball touches a player below t the waist, then it is considered an illegal hit. When simultaneous contact of the ball is made by opponents, the player on the opposite side of the net from which the ball falls shall be considered the player to have touched the ball last. The other player may participate in the next play and the simultaneous contact shall not count as one of the three hits allowed by that team.
