Bowling Score Calculator
Last updated: 2026-06-25
A bowling game has 10 frames. A strike scores 10 plus your next two rolls, and a spare scores 10 plus your next roll, all added cumulatively.
Tap the pins knocked down in each frame on the scoresheet below and the cumulative score and total are calculated automatically, bonuses included. A perfect game is 300 points.
Bowling Scoresheet
Current Total
0
Enter roll 1 of frame 1.
X = strike, / = spare, − = miss (0). A frame's cumulative score appears only once its bonus rolls are locked in.
How to Use
- Select a frame — Enter rolls starting from frame 1. The frame you are currently entering is highlighted in blue.
- Enter pins — Tap the number of pins knocked down (0-10) for each roll. Knock down all 10 at once for X (strike); if two rolls total 10, it shows / (spare) automatically.
- Read the score — As soon as a bonus is locked in, the per-frame cumulative score and total are calculated automatically. Tapped wrong? Use "Undo Roll" to go back.
How Bowling Scoring Works
A bowling game consists of 10 frames. Frames 1-9 allow up to two rolls, while the 10th frame allows up to three rolls including bonuses. Each frame's score is the pins knocked down in that frame plus any strike or spare bonus, and the cumulative score is the running total up to and including the current frame.
| Situation | Notation | Frame score |
|---|---|---|
| Open frame (two rolls < 10) | e.g. 4, 3 | Sum of the two rolls (4+3=7) |
| Spare (two rolls = 10) | / | 10 + next 1 roll |
| Strike (first roll 10 pins) | X | 10 + next 2 rolls |
| 10th-frame spare | e.g. 7 / 5 | 1 bonus roll added |
| 10th-frame strike | e.g. X X X | 2 bonus rolls added |
For example, if you strike (X) in frame 1 and then knock down 4 and 3 pins in frame 2, frame 1 scores 10+4+3=17 and frame 2 scores 4+3=7, so the cumulative score through frame 2 is 17+7=24. If the rolls after a strike or spare are not finished yet, the bonus is not locked in and that frame's cumulative score stays blank.

Frequently Asked Questions (FAQ)
How do you score a strike in bowling?
A strike is knocking down all 10 pins on the first roll of a frame. That frame scores 10 plus the pins from your next two rolls. For example, after a strike, if your next two rolls are 4 and 3, that frame scores 10+4+3=17.
How do you score a spare in bowling?
A spare is knocking down all 10 pins across both rolls of a frame. That frame scores 10 plus the pins from your next single roll. For example, after a spare, if your next roll is 7, that frame scores 10+7=17.
What is a perfect game in bowling?
A perfect game is 300 points. Rolling 12 consecutive strikes (including the two bonus rolls in the 10th frame) gives you the maximum 300-point game.
Why does the 10th frame have three rolls?
If you roll a strike or spare in the 10th frame, you earn bonus rolls. A strike adds two bonus rolls and a spare adds one, for up to three rolls. The pins from the bonus rolls are added directly to your score.
Is this bowling score calculator accurate?
This calculator applies the same official scoring rules as the United States Bowling Congress (USBC) — strike and spare bonuses and 10th-frame bonus rolls. It is a reference for practice and club games; official tournament scores follow event rules and automatic scoring results.
