What is it?
Ten-pin bowling uses a cumulative scoring system where strikes and spares earn bonus pins from subsequent deliveries. A strike (all 10 pins on the first ball) scores 10 + the next two balls. A spare (remaining pins on the second ball) scores 10 + the next one ball. The 10th frame allows up to three deliveries if a strike or spare is achieved.
How to use
Enter the complete frame score (including bonus pins already calculated) for each of the 10 frames. For example, if Frame 1 is a strike and the next two balls score 7 and 2, enter 19 for Frame 1. The calculator sums all 10 frames and computes the average per frame.
Example scenario
A perfect game (12 consecutive strikes): each of frames 1–9 scores 30 (10 + 10 + 10), and frame 10 also scores 30. Total = 300. A typical recreational bowler averaging 7 pins per frame (with some spares) would score around 140–160.
Pro tip
Ball-by-ball automatic bonus calculation requires individual delivery inputs, which this calculator intentionally simplifies. For best results, tally each frame score from a completed physical scoresheet before entering. Average league bowlers score 140–170; serious amateurs score 170–200; professionals typically average 200+.
