As an experienced craftsman, skillfully unlocking screws and removing intricately interlaced metal plates, rings, etc. is your first goal. Click the screw and move the screw to an empty space. Unlock all screws to remove the metal plate. You need to plan each step reasonably and put down as many metal plates as possible at one time to save time and steps and avoid dead ends in the game. As the game progresses, the levels become more challenging. You need to think outside the box and plan wisely to solve these tricky levels. Focus and be prepared to push your limits.
