A FEW SIMPLE RULES
Don’t touch the master ball during play
If you touch it and prevent a goal, the other team gets a point.
Stay on your side
Only collect marbles from your own half. Don’t reach across the halfway line.
After each goal
Return the master ball to the centre. Share the marbles remaining on your side with your teammates. You don’t need four each again or have to pass any back to the other team.
