Ladder Golf Scoring and Rules:
If you look on the internet, you'll find many different rules for the game.  So it was determined by many people I know who have the game that the rules are determined by the owner of the game.  There are "official" rules on some sites, but since I own my game, these rules are my official rules and are what we go by.  You can find may variations on the internet.

We have played with up to 4 teams. The scoring gets a little confusing, but it's fun.
A team consists of 1 or 2 people.  If there is only 1 person per team, then the teams have to move from ladder to ladder each time after the bolos are thrown - assuming that there are 2 ladders. If there are 2 people on each team, then 1 of each team will be at one ladder and the other team member will be at the other ladder.

When the bolos are thrown, the teams will alternate. That is, one team will throw a bolo, then the next team throws theirs, etc until all the teams have thrown 1 bolo and then they do it again until all the bolos are thrown.
We have 5 bolos for each team because the golf balls came in a package of 3 colors of 10 each color. If you only have 3 bolos for each team then that's OK. The game may take a little longer is all.

The idea of the game is for one team to reach the score of exactly 21 before the other team(s) does. 

• The ladders are placed about 15 to 25 feet apart . To make the distance consistent each time, I made a rope with a loop in one end and 3 loops near the other end. One loop would make the distance 15 feet, the next 20 feet and the third loop was 25 feet.  We seem to like it the best at about 20 or 25 feet.
• Each team will have at least 3, 4 or 5 bolos of the same color.  We got the colored golf balls at Walmart which had 30 balls of 3 different colors, so we made 5 bolos for 3 teams. Since then, we have added white bolos to make a 4th team.
• To begin the game, determine the initial order to toss the bolos (this is only for the first round). .
  Thereafter, the order is determined by the team that made the most points (positive or negative). They will go first, the team with the next most points goes next etc.  
• The score for each round is not counted until the round is over.
• In order for a bolo to be counted, a ball must be over each side of the ladder rung. (if it's hung on a score tee, the tee can be removed to see if it will hang over the rung)
• You can have as many teams as desired. We've played with up to 4 teams with no problems.  Each team must have the same number of bolos - each team having their own color.
• The top rung is worth 3 points, the middle rung is 2 points, and the bottom rung is worth 1 point.
  If all teams have a bolo on the same rung, they cancel each other out. Example: if the game is with 2 teams and they both get a bolo on the top rung, then  those 2 bolos are not counted. If team A gets another one on the top rung, it IS counted (until team B gets another one on the top rung).  If there are  3 or 4 teams, then in order to be canceled out, there has to be a bolo from each team on the same rung.  Then only those 3 or 4 are not counted in the score for that round.
• The game is to 21 points and it must be won exactly.  If a team gets more than 21 points, then all of that teams points for that round are subtracted from the current score of that team. 
• If 2 teams get 21 on the same round then they will continue playing and must beat the other team by at least 3 points at the end of a round. The other teams that did not have 21 points are dropped out.
• If you throw a bolo and it bounces back more than half way (to where you are throwing it from) then you are allowed to throw it again - but you don't have to.
• Each team must throw all of their bolos. You don't have to try to make it on the ladder,  however, they have to be thrown (tossed) toward the ladder.
  
         I think that it was originally meant for only 2 teams, similar to horseshoes, but we played it with 4 teams and had no problem.  Conceivably, it could be played with more teams if you had enough different colored bolos. It could get kind of confusing, however.
    A suggestion we found on the internet was to make the bolos using tennis balls for the younger kids.  They would be much safer.
