Unscrew Master: Nuts & Bolts is a satisfying, physical puzzle game that taps into the same addictive logic as games like 'Screw Puzzle.' The premise is simple: you must unscrew bolts from various layered planks to let them fall and clear the board. However, the 2025/2026 version adds a lot of polish to the physics—planks swing, collide, and slide based on their center of gravity, making every move a spatial calculation.
The tactile feedback is the star here. The 'clink' of the metal and the soft 'thud' when a plank falls provides a fantastic ASMR experience. While the early levels are meditative, the 'Master' levels introduce timed bombs and magnetic bolts that require split-second planning. It’s a great 'coffee break' game—easy to pick up, challenging to master, and incredibly rewarding to finish. It’s a solid entry into the mechanical sorting genre that prioritizes satisfying physics and clear logic.

Always look for the plank that is 'pinned' at only one point. These pieces will rotate around that bolt, potentially knocking other pieces loose or covering up empty holes you need. Clear the 'swinging' pieces first to keep your board predictable.

You only have a few empty slots to place your removed screws. If all holes are filled and no planks have fallen, it's game over. Try to clear a plank that covers its own holes as early as possible to 'recycle' those slots for the next set of bolts.
In Bomb levels, you must unscrew the bolts attached to a timer. If the timer hits zero before the bomb plank falls, the level resets.
