Screw Unbolt 3D: Color Sorting Puzzle

Put your logic and spatial reasoning to the test with this captivating 3D mechanical puzzle sorting game. Set against intricate structural models crafted from metal plates, beams, and colorful fasteners, your goal is to systematically unbolt screws and organize them into corresponding color-coded toolboxes. Featuring intuitive physical controls, vibrant visual presentation, and hundreds of mind-bending levels, this relaxing yet brain-teasing puzzle offers a deeply satisfying experience for players seeking a smart mental workout.

The core mechanic centers on precision unbolting and inventory management. Each puzzle model is held together by multi-colored screws that must be removed in a logical order to free the attached structural plates. However, available holding slots in your color boxes are strictly limited to three bolts at a time. Unscrewing bolts without matching open box slots will fill up your temporary holding tray, risking a complete lock if you run out of space before a set is cleared.

To master the most complex 3D structures, take time to rotate the object full 360 degrees before making your first move. Examine underlying layers to identify which top-level bolts are currently blocking access to lower fasteners. Prioritize clearing complete color sets of three to free up storage slots on your board immediately. Planning your sequence several steps in advance ensures you never get stuck with a full tray, allowing you to dismantle complex structures cleanly and advance through higher difficulty tiers.
