The ball is caught and immediately thrown over the net (play 1 time).
The player throws the ball as he catches it. When the player has thrown the ball, he/she will go to the wall (in the back of the field or on the side), touches it, and comes back into the field.
The other players have rotated a spot.
When someone throws a foul (in the net or outside), he has to run around the field of the opponent
Possibly...chaos, in which you have to play the ball instead of catch it.
