The object of the game is to earn points by tossing metal washers, usually around two inches in diameter, and 1/8 inch thick, toward a hole, usually denoted by a can or PVC pipe, known as the cooter, often in a box. Washer pits and boxes vary in size and shape, but a standard for one-hole washers is 16 in × 16 in × 4 in, with a cylindrically-shaped cup (4½ inches in diameter and 5 inches in height) located in its upper surface. Boxes are placed approximately 20 feet away from each other, a distance often determined by a string attached to the front of each box. However, if a string is not attached to the box, one may take 10 paces from box-to-box, this will usually denote 20 feet.
