screw bolt 3d

Screw Bolt 3D is a free online mechanical puzzle game where you rotate, tighten, and loosen screws and bolts to solve increasingly complex 3D structures. Each level presents a mechanical assembly that you need to take apart or put together using precise twisting and timing. The physics feel realistic enough that every successful unlock gives you a genuine sense of satisfaction.

The game starts simple but quickly layers on new challenges – bolts hidden behind other parts, screws that need loosening in a specific order, and color-coded components that guide your strategy. The 3D visuals make it easy to spot which bolt connects to what, and the smooth rotation controls respond well whether you're on desktop or mobile. Take your time on each puzzle; rushing usually means stripping the wrong bolt first and blocking your progress.

Screw Bolt 3D is a great pick for fans of mechanical puzzle games, logic games, and 3D brain teasers you can play instantly in your browser. If you enjoy nuts and bolts puzzles, physics-based puzzle games, or satisfying disassembly games online, this one hits that spot without any fuss. It works well as a quick mental workout during a break or a longer puzzle session when you want something hands-on and methodical. No download, no sign-up – just jump straight into the mechanics and start solving.
