In bowling, the score is kept using a system that tracks the number of strikes, spares, and open frames. Each frame provides an opportunity to knock down ten pins, with points awarded based on the number knocked down and bonuses for strikes and spares. A strike earns the bowler ten points plus the total of their next two rolls, while a spare grants ten points plus the next roll. The cumulative total is calculated over ten frames, determining the final score and ultimately the winner.
