Bowling Pinfall Calculator

Summary

Type the pins knocked down on each roll and get your bowling score with strike and spare bonuses applied automatically.

How it works

1. Type the pinfall for roll 1 of frame 1 (0 to 10).
2. If the first roll is not a strike, type the pinfall for roll 2 of that frame.
3. Repeat for each of the 10 frames; the 10th frame allows a third roll after a strike or spare.
4. Strike and spare bonuses are added to the frame automatically once the bonus rolls are known.
5. The running score and final total update live as you type.
6. Use "Load Sample" to see a filled-in example, or "Reset" to clear every field.

Use cases

• Re-enter pinfall from a paper scoresheet to double-check the printed total.
• Check a scoring dispute by typing in the exact pins knocked down per roll.
• Practice reading a scorecard and predicting frame totals before checking the answer.
• Verify league software output by cross-checking with an independent calculation.
• Teach someone how strike and spare bonuses roll into the frame total.
• Reconstruct a final score from a partial or smudged scoresheet, roll by roll.
