Ten-pin scoring rules built in

This calculator applies the official ten-pin bowling scoring rules, including the trickiest part: bonus scoring for strikes and spares that can only be finalized once you know your next roll or two.

Strike (X)

Knocking down all 10 pins on the first roll ends the frame early and scores 10 plus the pins from your next two rolls.

Spare (/)

Clearing the remaining pins on your second roll scores 10 plus the pins from your very next roll.

Open frame

If pins remain standing after two rolls, the frame simply scores the total pins knocked down in those two rolls.

Tenth frame

A strike or spare in the tenth frame earns one or two extra bonus rolls in that same frame, so the bonus can always be scored.

Bowling Score Calculator FAQ

How is a strike scored?

A strike is worth 10 pins plus the number of pins knocked down on the next two rolls. The frame's score is not final until those two rolls happen.

How is a spare scored?

A spare is worth 10 pins plus the number of pins knocked down on the next roll. The frame's score is not final until that next roll happens.

Why does the tenth frame allow three rolls?

If you strike or spare in the tenth frame, you earn one or two bonus rolls so a strike or spare there can still receive its full bonus.

What is a perfect game?

A perfect game is 12 strikes in a row (a strike in every one of the ten frames plus two bonus strikes in the tenth), for a maximum score of 300.

Is my scorecard saved anywhere?

No. Everything runs in your browser only. Refreshing the page clears the scorecard.
