In the strategic sorting puzzle, the goal is to sort the mixed color nuts onto the screws in such a way each screw only holds nuts of a single color. The first levels of the games serve as an introduction while more advanced stages certainly require higher level considerations and planning. Each nut can only be placed on a vacant screw or a screw with a top nut that matches the color underneath it. Progressing through levels introduces more colors and more complex configurations. In hard mode, colors are hidden under the upper nuts to conceal them and test your adaptability. Each level solved rewards a satisfying and motivating sense of achievement which, in turn, spurs the desire to develop better solutions. With clever twists and increasing challenge, this classic puzzle offers vibrant and logic-based brain training.
