3D Screw Master: Nuts & Bolts Puzzle

Challenge your spatial reasoning and problem-solving skills in 3D Screw Master, an addictive mechanical logic puzzle game. The objective is straight forward yet deeply strategic: carefully unscrew metallic bolts holding various wooden and metal planks together in a multi-layered 3D space. As each fastener is removed, physics-based gravity causes freed planks to drop away, revealing lower layers and new screw holes needed to disassemble the complex structure entirely.

Success requires careful tactical planning because available open screw holes are strictly limited on each board. If you remove a bolt without having a free open socket to place it into, your current move invalidates, forcing a level retry. As you progress through dozens of increasingly complex stages, puzzles introduce pinned overlapping boards, glass barriers, and locked color-coded fasteners that require specific dismounting sequences to solve cleanly.

To master advanced levels without getting stuck, analyze the full assembly before making your first move. Identify top-layer planks that block lower elements and prioritize freeing them early. Reserve empty pin sockets for strategic temporary holding areas when shifting tricky fasteners. Take your time to plan moves sequentially, ensuring that every unbolted plank falls freely without blocking key structural holes below, earning maximum reward points and unlocking new tool themes.
