You stand by a basket in groups of 3/4. Number 1 stands under the basket as a catch, number 2 stands under the basket as a support, number 3 stands in front of the field and possibly number 4 is defender of number 2.
The ball starts with number 3.
In the meantime, number 2 walks to the front of the field to get in the support.
At that moment number 4 passes the ball to number 2.
Number 2 makes sure that the ball is turned around so that the feet pass each other.
After doing this three times, each player changes position.
