As this might be a bit dull the following variations are possible:
- Add balls, up to 9 shouldn't be a problem.
- Change direction from anti-clockwise to clockwise on a signal.
- Let the players tap their feet while passing.
- Change the pass type on a signal.
- Appoint different passes to each ball.
It might be handy to have different colored balls (orange chest pass, red white blue bounce pass, orange white overhead pass etc)
