Bowling is a popular indoor sport where players roll a heavy ball down a narrow lane with the aim of knocking down pins arranged in a triangular formation at the end of the lane. A typical bowling game consists of ten frames, with each player taking turns to roll the ball twice in each frame.

Players aim to knock down all ten pins in a single frame, which is called a strike, or in two attempts, which is called a spare. The score of a frame is determined by the number of pins knocked down, with bonus points awarded for strikes and spares
