Duckpin bowling

Duckpin bowling is a variation of 10-pin bowling. The balls used in duckpin bowling are 4-3/4 in (12 cm) to 5 in (12.7 cm) in diameter (which is slightly larger than a softball), weigh 3 lb 6 oz (1.5 kg) to 3 lb 12 oz (1.7 kg) each, and lack finger holes. They are thus significantly smaller than those used in ten-pin bowling but are slightly larger and heavier than those used in candlepin bowling. The pins, while arranged in a triangular fashion identical to that used in ten-pin bowling, are shorter, smaller, and lighter than their ten-pin equivalents which makes it more difficult to achieve a strike. For this reason (and similar to candlepin bowling), the bowler is allowed three rolls per frame (as opposed to the standard two rolls per frame in ten-pin bowling).

Duckpin bowling centers are located in Connecticut, Massachusetts (principally in and near its South Coast communities), Rhode Island, Indiana (Fountain Square), Maryland (especially in the Baltimore area), Wisconsin, Virginia, and in suburban Washington, D.C.. There is also one located in Potter, Nebraska, the only one of its kind west of the Mississippi.
