Enter pins per roll — type a number, X for a strike, / for a spare, or - for a miss. A strike scores 10 plus your next two rolls; a spare scores 10 plus your next one roll; the 10th frame allows a third roll after a strike or spare. A perfect game is twelve strikes for 300.

Questions

How does ten-pin scoring work?

Each frame is worth the pins knocked down, plus bonuses: a strike adds your next two rolls, a spare adds your next one roll. The 10th frame gives a third roll after a strike or spare. A perfect game of twelve strikes scores 300.

How do I enter a strike or spare?

Type X for a strike, / for a spare, a number for a normal roll, or - for a miss. The running total under each frame updates as you go.
