Like any other sport, Volleyball has alot rules and restrictions.
6 players on a team, 3 in the front row and 3 in the back row
A maximum of three hits per side
A block does not count as a hit
If the ball touches the net and falls either back or over the net, it's playable
Rotations happen when you get a side-out. A side-out is when the other team serves but you when the point. Rotations are clockwise. When your team wins that point, the person who moves clockwise to the back right corner then serves.
