Bowling Score Calculator

How Bowling Scoring Works

Bowling uses a unique scoring system across 10 frames. Each frame gives you up to two rolls to knock down 10 pins. Your score is the total pins knocked down, plus bonuses earned from strikes and spares. The maximum possible score is 300, known as a perfect game.

Strikes

A strike (marked X) is when all 10 pins are knocked down on the first roll of a frame. The frame score is 10 plus the total pins from the next two rolls as a bonus. For example: Strike, then 7 and 2 on the next frame = 10 + 7 + 2 = 19 points for the strike frame.

Spares

A spare (marked /) is when all remaining pins are knocked down on the second roll. The frame score is 10 plus the pins from the next one roll as a bonus. For example: 6 then spare (4 remaining pins), then first ball of next frame is 8 = 10 + 8 = 18 points for the spare frame.

Open Frames

An open frame is when you don't knock down all 10 pins in two rolls. The frame score is simply the total pins knocked down — no bonus. For example: 5 then 3 = 8 points.

The 10th Frame

The 10th frame is special. If you throw a strike, you get two bonus rolls. If you get a spare, you get one bonus roll. These extra rolls complete the 10th frame scoring only — they don't earn additional bonuses. The maximum 10th frame score is 30 (three strikes).

Frequently Asked Questions

How is a bowling score calculated?

A bowling score is calculated by adding the pins knocked down in each frame plus bonuses. A strike (all 10 pins on the first roll) earns 10 plus the next two rolls as a bonus. A spare (all 10 pins in two rolls) earns 10 plus the next one roll as a bonus. An open frame scores only the pins knocked down. The maximum score is 300 (a perfect game of 12 consecutive strikes).

What is a strike in bowling?

A strike occurs when you knock down all 10 pins with your first ball in a frame. It is marked with an X on the scorecard. The score for a strike frame is 10 plus the total pins from your next two rolls. For example, if you bowl a strike followed by 7 and 2, that strike frame scores 10 + 7 + 2 = 19.

What is a spare in bowling?

A spare occurs when you knock down all 10 remaining pins with your second ball in a frame. It is marked with a / on the scorecard. The score for a spare frame is 10 plus the pins from your next one roll. For example, if you bowl 7 then knock down the remaining 3 (spare), and your next roll is 5, that spare frame scores 10 + 5 = 15.

How does the 10th frame work in bowling?

The 10th frame is special because you can earn up to three rolls. If you throw a strike on your first ball, you get two more bonus balls. If you get a spare (knock down all pins in two balls), you get one more bonus ball. These extra balls are used only to complete the scoring of the 10th frame. If you do not strike or spare, you only get two balls. The maximum 10th frame score is 30 (three strikes).

What is a perfect game in bowling?

A perfect game in bowling is a score of 300, achieved by throwing 12 consecutive strikes (one in each of the first 9 frames, plus three in the 10th frame). Each of the first 9 frames scores 30 points (10 + 10 + 10), and the 10th frame scores 30 (10 + 10 + 10), totaling 300. A perfect game is considered one of the most impressive achievements in bowling.
