At forty levels of the Screw Escape game you will free multi-colored metal strips from the captivity of bolts. The planks are fastened with at least six bolts and everything needs to be unscrewed and removed so that the plank is free and slides out of the playing field, disappearing completely. When removing the bolts, you must mark in advance the place where you will move each bolt. If there is no free space, the escape will be unsuccessful. You also need to make sure that there is not another one lying on top of the bar that you are going to release, otherwise this will also not allow you to remove the object in Screw Escape.
