FAQ
How do I input a strike?
Enter [10] for a strike in any frame. In the 10th frame, if you get a strike, you get two bonus rolls, so you might enter [10, x, y] where x and y are the pins knocked down in the bonus rolls.
How do I input a spare?
Enter two numbers that add up to 10, e.g., [7,3] or [0,10] (though 0,10 is not typical as the first roll would be a strike). The calculator will recognize it as a spare.
What if I have an open frame?
Enter the two rolls that do not sum to 10, e.g., [9,0] or [8,1]. The score for that frame is simply the sum of the two rolls.
Can I use this for duckpin or candlepin bowling?
This calculator is designed for ten-pin bowling. Other variations have different scoring rules and number of pins.
Is this calculator free to use?
Yes, it's completely free and requires no registration.
