Bowling Score Calculator
Enter the number of pins knocked down on each roll, in order.
This result is an estimate only. Double-check important figures before relying on them.
How it is calculated
- Open frame: the pins from both rolls
- Spare: 10 + the next roll
- Strike: 10 + the next two rolls
- 10th frame: a strike or spare earns bonus rolls
For win percentages across games, use the win percentage calculator.
Worked example
Rolls 10, 7, 3, 9, 0 …:
- Frame 1 strike: 10 + 7 + 3 = 20
- Frame 2 spare: 10 + 9 = 19, running total 39
- Full game total: 167
Why your number may differ
Scores wait for bonus rolls, so a strike in the last scored frame shows once the next rolls are entered.
