Nuts and Bolts: The Ultimate Screw Puzzle Game | Play Free!

There's a deep, primal satisfaction in the click of a well-turned wrench and the sight of a perfectly disassembled machine. Welcome to Nuts and Bolts, the ultimate brain-bending puzzle that will test your logic, foresight, and spatial reasoning. This isn't just a game; it's a mechanical gauntlet. Your task is to analyze a complex web of overlapping metal plates and figure out the correct sequence to unscrew the nuts and bolts to clear the board. One wrong move and you'll lock the puzzle forever. The core loop is brilliantly engineered for satisfaction: play and earn coin for every level you conquer, then use your earnings to unlock new tool skins and intricate plate designs.

The 'Chain Reaction' Challenge Update!

Just when you thought you'd mastered the mechanics, we've added a whole new layer of complexity! The Chain Reaction Challenge update is now live, introducing 50 new levels featuring interconnected plates and gears. Unscrewing one bolt might cause a gear to turn, which in turn moves another plate and blocks a previously open screw hole. You must now think three or four steps ahead to predict these mechanical chain reactions. It’s a true test for veteran puzzle solvers, and we break down our favorite solutions on our official blog.

How to Play: The Mechanic's Manual

The controls are simple, but the solutions are complex. Your goal is to clear all the metal plates from the board.

• Select a Nut: Click on a nut you wish to unscrew.
• Move a Nut: Click on an empty, available screw hole to move the selected nut there.
• The Objective: A plate will fall off the board once it is no longer held in place by any nuts. Unscrew them in the correct order to clear the level!

The Blueprint: Your Questions, Answered

What exactly is a Nuts and Bolts puzzle game?

A Nuts and Bolts game is a sequential logic puzzle. The challenge lies in figuring out the correct order of operations. You are presented with a layered arrangement of plates held together by nuts and bolts. You must strategically move the nuts to free up the plates one by one until the board is clear. It’s a true test of planning and problem-solving.

What's the best strategy when you're stuck?

Think in reverse. Instead of asking, "What should I remove first?" ask, "What is the very last plate that can possibly be removed?" Identify it, and then see what's holding it in place. By working backward from the solution, you can often unravel the most complex puzzles. This kind of reverse-engineering is a skill that's vital in many of the best adventure puzzle games online.
