Players form a circle with a 40m radius, use 1 ball per 6 players. Same amount of players as there are balls start in the middle, all balls start on the outside of the circle
(A) kicks to (B) then sprints to replace (B)'s position in the centre
(B) kicks to (C) then sprints out of the centre towards (C)
(C) kicks to (A) who has replaced (B) in the centre, then sprints after their kick into the centre.
(A) kicks to (D) then sprints out again
This process occurs with all balls around the circle
