Ten-pin bowling is a sport in which a player (called a “bowler”) rolls a bowling ball down a wood-structure or synthetic (polyurethane) lane and towards ten pins positioned at the end of the lane. The objective is to score points by knocking down as many pins as possible.

Ten-pin bowling was introduced to South Koreans by American GIs during the Korean War, and it is still a popular sport in South Korea today.
