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, Ohio, and in suburban Washington, D.C. There is also one located in Potter, Nebraska, the only one of its kind west of the Mississippi.
In the state of Maine, in the historical renovation of Fort McKinley on Great Diamond Island, Portland, there is a private two-lane duckpin bowling alley. It is located within the Recreation Center of the Diamond Cove Community Home Owners Association. Use is restricted to members of the community, guests of home owners, renters of the community condominiums and registered guests of The Inn at Diamond Coven.
