A simple passing drill that can be fun.
Put an uneven number of player,s in this case 9, around a circle.
Give a puck to player 1 and 9 and let them pass to the right skipping one player.
So the pass sequence will be 1-3-5-7-9-2-4-6-8-1 or 9-2-4-6-8-1-3-5-7-9 depending on your starting point.
The goal is for one puck to overtake the other.
As this might be a bit dull the following variations are possible:
Add pucks up to 9 shouldn't be a problem.
Change direction from anti-clockwise to clockwise on a signal.
