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.
Bowling is one of the oldest and most popular games in the world. Bowling is a sport that can be dated back to circa 3200 BC. In the 1930's, a British anthropologist named Sir Flinders Petrie discovered a collection of objects in a child's grave in Egypt that appeared to be used for a primitive form of bowling.
