How a level plays
Tap a screw that nothing covers. It spins out and flies to the box of its colour; three screws fill a box. If its box is not open yet, it waits on the spare tray (5 slots). A plate falls once all its screws are out, showing the screws underneath. Clear every screw to win, and keep a free slot on the tray.
