Now that I have your attention... Defining the rules of the washers game has been similar to a poker game. Depending on where, or who you are playing with, rules can be called out in various ways. It is to bad there are no set official set of rules given.
I am building an octagon one hole game. As a newbie building my first game the rules seem to be whatever you want it to be. I read two, three, or four washers can be used. Distance can be any range from 10-40 feet. Measurements can be from the front of the game, or can be from cup center to cup center. Some say 25 feet, some say 21 feet. Points scored can be 3 and 1, or 3, 2, and 1. Points can be cancelled out, not cancelled out. Cups can be 3", must be 4", or the official 4.5". Washer sizes can vary from 2"-3"+, and a bunch of other variations.
If you are still reading this, thanks for letting me vent on my own. I guess I will just make up my own rules, and throw the washers toward the cup. I just wanted to find an official game rule that everyone agrees on. Just like poker, who ever calls the game, that is the rule for the day.
