A starting line is drawn across the ground. At right angles to it a row of potatoes is placed for each player in the heat. The potatoes should be two yards apart and eight in number. (This is the official number and distance for the Amateur Athletic Union; the number varies in unofficial games, but should be equal for the different rows.) The first potato should be two yards from the receptacle, which is usually placed on the starting line, one beside each competitor. This receptacle should be a pail, basket, box, or can. The official dimensions of the A. A. U. call for its being not over two feet in height, with an opening not over thirty-six inches in circumference. In handicap events the starting mark is paid from the rear of the can. The potatoes are replaced on the marks before the beginning of each heat, the game in this form consisting solely of gathering them up, not in placing them. There is no rule against tossing a potato into the receptacle, but it is poor policy to do so, as it increases the risks of failure.
The contestants start, as for a race, in response to the starter's signals, "On your marks!" "Get set!" "Go!" The game consists in picking up the potatoes one at a time and placing them in the receptacle. The potatoes may be picked up in any order desired. A potato dropped, however, must be picked up before another potato be touched, or the player is disqualified. Similarly, a potato missing the receptacle or bounding out of it must be placed in it before the next potato be touched, or the player is disqualified. When all the potatoes have been placed in the receptacle, the player finishes by dashing across a finish line, a tape, or strand of worsted, stretched five feet back of the receptacle. As in all races in athletic form, a player is disqualified for interfering with any other competitor, or for touching the finish tape with the hands or arms: the tape should be breasted. The winners in each heat play a final race; or, with large numbers competing, semi-finals before the finals. Where small numbers are competing, those finishing first, second, and even third, may be entered for the final trials. In case of a tie, both competitors are entered for the next (final, or semi-final) heat, or, if tied in the final heat, the tied competitors play again.
