Indoor variations

• Ten-pin bowling: In the United States, tenpins is the best known form of bowling, which in both amateur and professional versions, is also played around the world, making it one of the largest participation activities. The balls have two or more drilled holes in which to insert fingers for gripping the ball.
• Candlepin bowling: Played in eastern Canada and in New England, a variation of ten-pin bowling, with "double-ended" pins that are the tallest in any bowling sport.
• Duckpin bowling: Commonly found in the mid-Atlantic and southern New England states and eastern Canada, is another variation of ten-pin bowling involving small, squat pins, sometimes with rubber at their widest points (rubber band duckpin bowling). The official small pin is about 9 3/8 inches (24 cm) high and 4 1/8 inches (10 cm) in diameter at its widest part. It weighs no more than 1 pound 8½ ounces (700g). The standard duckpin ball has no finger holes. The maximum diameter is 5 inches (13 cm). For duckpins and candlepins, the maximum weight of the ball is 4 pounds 12 oz (1.7 kg).
• Five-pin bowling: Played in Canada.
• Nine-pin skittles: Played in Europe.
• Bumper bowling: Ten-pin bowling played with the addition of barriers to the channels, making "gutter balls" nearly impossible, popular with children's parties.
• Power Wheelchair Bowling: Recent advances have made it possible for people who are severely disabled to bowl alongside able bodied players through use of a ramp that attaches to the wheelchair. This sport is approved by the United States Bowling Congress.
