X1 plays to X2
X2 plays back to X1
X1 plays back to X2 and moves counterclockwise after passing (1/4 circle)
X2 plays to X3 (position taken by X1) and also moves counterclockwise after passing (1/4 circle)
X3 plays to X1
X1 plays to X2 and moves counterclockwise again after the feed (1/4 circle); assumes the starting position of X2 accordingly
X2 plays to X3 and joins the waiting group (1/4 circle shift)
X3 and X1 restart the exercise
After a few passes change direction (rotate clockwise).
Later, the starting player can independently decide in which direction to start.
