The job

Bowling's running totals depend on future throws — a strike's score isn't known until two more balls land. Scoring by hand is exactly the arithmetic people get wrong on lane 9.

Tap each throw

After each ball, tap how many pins fell. The pin pad only offers legal counts — you can't mark 7 after a 7. Running totals fill in as bonuses resolve; the frame shows '—' until its bonus is decided.

A perfect game scores 300; the classic example game (X, 7/, 9-, X, -8, 8/, -6, X, X, X81) scores 167.
The tenth frame allows up to three balls — the pad adapts automatically.

Scoring refresh

Spare = 10 + next ball. Strike = 10 + next two balls. Chained strikes stack — three in a row make the first frame worth 30. Nothing is saved; start a new game with reset.
