Bowling is a sport the whole family can enjoy.
Bowling, sometimes called tenpins, is an indoor game played on a polished wooden or synthetic floor by individuals or teams. Bowling is most popular in the US where more than 80 million people actively participate.
In the US game contestants roll balls, which have two or, commonly, three finger holes for gripping, toward ten 15-in. wooden pins. The pins are arranged in triangular formation, with the headpin 60 ft. from a foul line. The balls, made of a variety of materials are 8.5-in. in diameter and must not weigh more than 16 lb. The bowler, who rolls the ball underhand, has a runway at least 15 ft. long from which the ball may be released.
A bowling game is divided into 10 frames: the object of the game is to knock down all of the pins on the first or, if necessary, the second of the 2 rolls allowed in each frame. Each pin that is knocked down counts as 1 point. Knocking down all the pins with the first ball is called a strike and is scored as 10 points plus a bonus determined by the total points gained in the next 2 rolls. If a bowler should continue to roll only strikes throughout the game (a total of 12 attempts, because 2 bonus tries are allowed in the tenth frame), the result would be a rare prefect game 300. If 2 deliveries are needed to knock down all of the pins in a frame, the outcome is called a spare. A bowler is then awarded points plus a bonus of the score on the next roll. If a spare is made in the final frame, one extra roll is allowed and that is added to the score.
