Pe
Volleyball uses rally scoring.
Each team is permitted three hits per side.
Players rotate "clockwise" after every side out.
The optimal order of hits is: bump, set, spike.
You cannot spike the serve.
Players cannot touch the net.
A ball hitting the line is good.
The same person may hit the ball 2 consecutive times as long as the first hit was
If a ball hits the ceiling and comes down on the same side (prior to 3 hits), the team may hit again.
If the ball hits the net on the serve and still goes over it is "good".
