Bowling is a sport where players score points by knocking down pins with a bowling ball. The bowling ball is rolled down a flat surface to the location of the pins. There are many forms of bowling, with ten-pin bowling being the most commonly played.

Bowling is a popular sport dating back to ancient times. It involves rolling a heavy ball down a smooth lane towards a group of pins. There are many different varieties of bowling, all using the same basic rules and equipment.

Knock down every pin in a frame by rolling a heavy ball.

Each game consists of ten frames, or opportunities to knock down ten pins. Players roll the ball twice, unless a strike is scored. Each pin is worth one point when knocked down. A strike counts for ten points, plus the total number of pins knocked down on the next two rolls. Spares count for ten, plus the total number of pins knocked down on the very next roll.

Early forms of bowling can be traced back to ancient Egypt, and years later in Europe and the Middle East. Modern bowling was first played in Medieval Europe with stones thrown at wooden clubs. Bowling became so popular in early 19th century New England that is was overrun by gambling, and eventually outlawed. As a way to circumvent the law, which banned "bowling at nine pins," the game 10-pin was invented. 10-pin became extremely popular, which led to the creation of the American Bowling Congress (ABC) in 1895. The ABC established standard rules and specifications for balls, pins and lanes. It also became the governing body for all domestic competitions and championships. Today bowling is an extremely popular recreational and competitive sport, with bowling alleys located in cities and towns throughout the world.
