A fairground wheel for the Kids Zone: call a light, wind the wheel up and let it go. It slows down on its own because the thing driving it is a capacitor running out, exactly the way the bench recipe does it — nobody wrote the slowdown. Stop it yourself or let it land. Tap to play, nothing saved between rounds.
Call a light, then wind the wheel up and let it go. It slows down all by itself, because the thing driving it is running out — and wherever it stops is the answer.
Tap a light to call it.
