24 players or less: have one group and gradually introduce multiple balls. 24+ split into 2 groups and create 2 playing areas..
Groups (A), (C) and (E), kick, get a return handball, kick again.
Kickers join to the FIRST station they gave to (the next letter in sequence), so these players MUST REMEMBER to go back a group, or you'll get uneven numbers
(A joins B), (C joins D), (E joins F).
(B), (D) and (F) simply mark and handball back to the kicker.
Handballers, like kickers, progress to the next station.
(B joins C), (D joins E), (F joins A).
This means everyone has a turn at [kick-receive-kick], then [mark-handball] next time.
Progression: Introduce a second/third ball if numbers permit. Throw-in a reversal of direction.
