Some careless design engineer with an incomplete education created a complete mess on the wooden panels in the Nut & Bolt Screw Puzzle Game. At each level, he screwed different colored strips onto the panel in a random pattern. The design is completely incomprehensible and not adapted to anything. Your task is to disassemble the ridiculous structure, clearing the panel from the slats. Each strip is attached with two or more bolts. You must unscrew the bolts and move them to the free hole. This way, only the bolts should remain on the panel in Nut & Bolt Screw Puzzle Game.
