Snake Pit

Snake Pit is an outdoor recreational game similar to horseshoes, in which players toss an oversized washer into a square wooden box with a hollow pipe coming up from the base of the box (the "snake pit").

Rules

A game set includes two open square boxes (usually made from wood) and six oversized washers. Inside each wooden box is a tube coming up as high as the box surrounding it. A small hole on the bottom edge of the box is used to put a rope through. The rope is tied on the inside on one side, and leads to an identical wooden box on another.
A player receives two points for a toss that lands in the box, and five points for one that lands in the "snake pit." The first player to receive 11 points wins the game.
Snake pit may be played one-on-one or two-on-two. The two-on-two version requires one person from each team to be on either side, thus making two opponents on each side. One contestant shoots three washers, then his opponent (the one next to him) shoots his three. First team to 11 points wins.

Cancelling

If two opposing players land the same kind of shot consecutively, they are considered to cancel each other out. For instance, if the first shooter hits a 2-pointer, then the person on his side also hits a 2-pointer, neither shot counts. The same applies if consecutive "snake pits" are hit. If a throw ends with a washer leaning on an edge of the box, whether it has landed that way directly or if it has bounced or rolled there, the game ends immediately, and the team which shot the "leaner" wins.
