🎳 Bowling

👆 One tap at a time

Each throw is built up one step at a time, and you only ever tap once per step:
1. Where to stand — a marker slides along the line. Tap to stop it.
2. Which way to aim — the arrow swings. Tap to stop it.
3. Spin — on the Pro lane only, curve the ball left or right.
Then the ball rolls. Tapped too early? ↩️ Back undoes a step.

🛟 Bumpers, Classic, Pro

Bumpers: the sides bounce the ball back, and a dotted line shows exactly where it will go.
Classic: real gutters, and the line only shows the start.
Pro: no line at all, faster markers, and you can add spin.

✖️ Strikes and spares

All ten with the first ball is a strike (X), and you get the next two balls added on top.
All ten using both balls is a spare (/), and you get the next one ball added on top.
That's why a frame shows – for a while: its score genuinely isn't decided yet. Watch it fill in when you throw again.

🔟 The last frame

If you strike or spare in the tenth frame you get an extra ball, so the last frame can have three. Twelve strikes in a row is a perfect game: 300.
