Volleyball drill: game

The four quart fields have been numbered (see triangles in picture) The goal is to reach field 1 as a team by not making any mistakes!

The game begins with bringing the ball into the field. This can be done by the trainer, but also a player can throw the ball over the net.

The pair that receives the ball plays the ball over the net by playing three times (mandatory!) etc..
The team that makes a mistake leaves the field (in case of 5 teams) or goes to field four (in case of 4 teams).
The other teams rotate a field.
So when the team in field two makes a mistake, they leave the field, field 3 rotates to field 2, field 4 to field 3, and the fifth team goes to field 4 .

After 10 minutes the game stops, and the team in field 1 is the winner!
