Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Parse frame boundaries, validate rack constraints and apply strike and spare bonuses.
Strike=10+next two rolls; spare=10+next roll; tenth frame sums its own rolls
Worked example
Twelve strikes form a complete perfect game scoring 300. Ten frames of 5 then 5 with a final bonus 5 score 150.
Assumptions and input details
Numeric credited pinfall only: no X or slash notation. Use zero for a credited miss or foul. Complete traditional ten-pin games only; missing or extra rolls and impossible racks are rejected. Foul adjudication and alternative scoring conventions are excluded.
