Bowling refers to a series of sports or leisure activities in which a player rolls or throws a bowling ball towards a target. It is one of the major forms of throwing sports. In pin bowling variations, the target is usually to knock over pins at the end of a lane. In target variations, the aim is usually to get the ball as close to a mark as possible.
Five pin bowling is an indoor sport that was invented in 1909 by Thomas F. Ryan at the Toronto Bowling Club. This is a variation on the more popular, ten pin bowling game. Both the 5 pin and ten pin bowling games are available in most bowling alleys in Canada. In 5 pin bowling, the bowling pins are 25% smaller than in ten pin. The bowling ball itself is hand-sized, completely without holes and is easy to roll. At the end of the bowling lane, five pins are arranged in a V shape.
