Bowling Score Calculator

Summary

Enter your rolls for all 10 frames and instantly calculate your bowling game score with correct strike and spare bonus rules.

How it works

1. Enter the number of pins knocked down for each roll in every frame.
2. Use the "X" button to mark a strike (all 10 pins on the first ball).
3. Use the "/" button to mark a spare (all remaining pins on the second ball).
4. Strike and spare bonuses are automatically applied to produce the running frame total.
5. The 10th frame allows a bonus third ball when you roll a strike or spare.
6. Your final cumulative score is displayed at the bottom of the scorecard.
