A bowling alley is a facility where people can play the sport of bowling. It typically features multiple lanes, each equipped with a smooth surface for rolling bowling balls towards a set of ten pins. Players take turns trying to knock down as many pins as possible, and scores are calculated based on the number of pins knocked down in each frame. Bowling alleys often include additional amenities such as a snack bar, arcade games, and seating areas for spectators. Many alleys also host leagues and tournaments, allowing players to compete against each other in a friendly environment. Popular bowling balls and shoes are available for rent or purchase on-site.
