How Bowling Scoring Works
Frames and Balls
A bowling game consists of 10 frames. In each frame, you get up to two balls to knock down all 10 pins. Your score for each frame depends on how many pins you knock down and whether you earn strike or spare bonuses.
Strikes
A strike is when you knock down all 10 pins on your first ball. It's marked with an "X" on the scorecard. A strike scores 10 plus the total of your next two balls as a bonus, which is why consecutive strikes are so valuable.
Spares
A spare is when you knock down all remaining pins on your second ball. It's marked with a "/" on the scorecard. A spare scores 10 plus the total of your next one ball as a bonus.
Open Frames
An open frame is when you fail to knock down all 10 pins in two balls. Your score for that frame is simply the total number of pins knocked down, with no bonus.
The 10th Frame
The 10th frame is special. If you throw a strike, you get two bonus balls. If you throw a spare, you get one bonus ball. This means you can throw up to three balls in the 10th frame. After a strike or spare, the pins are reset for your bonus balls.
Perfect Game
A perfect game is 12 consecutive strikes — one in each of the first 9 frames, plus three in the 10th frame. Each strike in the first 9 frames scores 30 (10 + 10 + 10), giving you a perfect score of 300.
