Unscrew in the right order. Keep every plank level.
Pull screws out into matching trays, but every screw you take shifts the weight on its plank. Keep everything level while you sort. Locks and multi-turn screws make you plan several moves ahead.
Stars: three for a clean run with no undo or help, two if you used undo, one with hints or rewinds.
Play a level and your stars and progress show up here. They are saved on this device, and on every device once you sign in.
