Multi-colored metal strips are bolted to a wooden slab on the Bolts and Nuts in 3D playground! Your task is to unscrew all the bolts so that the planks fall off and the slab becomes empty. When unscrewing a bolt, you must know in advance where you will move it. There must be free holes for your bolt. If there are two or three planks, the task seems simple, but if there are more planks and they are screwed on each other, the task becomes more complicated. Think before you start dismantling a metal structure in Bolts and Nuts in 3D!.
