The minimum number of players for this game is nine. You will need five beanbags for each group of nine or more players.
For every group of nine or more players, draw three concentric circles on the floor. They should be about one, two, and three feet in diameter. About twenty feet from the circles, draw a straight line to serve as the baseline. In each group a referee is appointed, and sides are chosen. The players alternate from the two sides. Each in turn stands with his toe on the baseline, and tosses the five beanbags, one after another, toward the circles. Each beanbag that falls within the inner circle counts fifteen, each within the second circle counts ten, and each within the outside circle counts five.
You also can substitute a board for the circles on the floor. The board should be about 2½ by 2 feet, with a large hole cut near the upper left-hand corner and a small one near the lower right-hand corner. It should stand at an angle of forty-five degrees. When a board is used, the point count is fifteen for every bag thrown through the small hole, ten for every one through the large hole, and five for every bag remaining on the board at the end of the player's turn. Whichever group totals 100 points first wins.
