ladder golf

Ladder golf's idea is to throw bolas (two balls tied together) so they would keep hanging from the rungs.
The top rung gives you 3 points, middle rung gives you 2 points and bottom rung gives you 1 point. If you manage to get all three to the same rung, you get 1 bonus point. If you manage to get one bola on each rung, you also get 1 bonus point.
Your GOAL is to get exactly 21 points! If you get more, you go back to 0.
It is allowed to kick other players' bolas off the ladder.
