All of the players taking part stand in a line and wait for their turn.
One player at a time stands from the distance that you set and strike a ball, aiming for the ball to hit the crossbar.
If no one hits the crossbar then the closest one wins.
If more than one person hits the crossbar then the players who didn’t are out and the players who did hit it go into another round and keep doing that until there’s a winner.
