Puzzle & Brain

Play Nuts and Bolts Screwing Puzzle free in your browser. Unscrew pins, free wooden plates, and solve clever mechanical physics puzzles with zero downloads.

Nuts and Bolts Screwing Puzzle is an engaging physics-based brain teaser that turns mechanical disassembly into a satisfying spatial challenge. Each level presents you with a series of overlapping wooden or metal bars bolted onto a backboard. Your task is simple in theory but tricky in execution: remove screws one by one and relocate them into open holes so that every fastened piece drops away cleanly.

Unlike the fast-paced, reflex-heavy action of Doodle Jump, this puzzle provides a deliberate, thoughtful change of pace. There is no ticking clock pushing you into reckless mistakes, which lets you analyze the board, trace how plates overlap, and determine the exact sequence required to clear the screen.

How to play

The controls are completely straightforward and require only a mouse or touchscreen:

Select a bolt: Click or tap a screw that is currently holding one or more plates in place.
Choose an open slot: Click an empty hole on the board to fasten the screw into its new position.
Clear all plates: Free every bar so gravity pulls it off the playing field to complete the level.

Keep in mind that you can only place screws into vacant holes. If you fill all open slots before freeing a hanging piece, you will find yourself in a deadlock and need to restart the stage.

Practical tips for solving boards

Clearing higher levels requires understanding how weight and leverage behave as bolts are removed:

Free dangling ends first: When a plank is secured by two pins, removing one allows it to swing downward around the pivot. Use that momentum to expose covered holes underneath.
Target bottom layers: Pieces on top often obstruct the path of pieces underneath. Look for the uppermost bar that has no other wood resting on it and remove its fasteners first.
Preserve spare holes: Avoid using your last open screw hole unless that placement immediately causes a plate to drop and clears a new slot.
