About Wooden bolts and nuts

Anyone comfortable tapping a phone screen can pick this up cold — no reading required, no timing pressure, and no need to have solved a color-sort puzzle before. The only motor demand is a single finger: tap a plank to rotate it, then tap the bolt you want to unscrew. Each level presents a wooden board cluttered with bolts, nuts, rings, and ropes tangled together. The goal is to free every bolt by rotating planks so the bolt clears its neighbors and drops into an empty slot below. The visual feedback is instant — a bolt falls once its path is clear — so attention span can be as short as a single tap. The puzzle stays readable for anyone who processes spatial relationships one step at a time.

At first, it’s just a messy pile of screws, nuts, bolts, rings, and ropes. But the real fun is figuring out how to untangle them and get everything in its right place. Each level is a satisfying puzzle that makes you think ahead. It’s simple, addictive, and oddly calming once you click everything into order.

How to Play Wooden bolts and nuts

Tap a plank to rotate it 90 degrees, changing the orientation of the bolts and obstacles attached to it.
Tap a bolt that is free of any obstruction to unscrew it and let it drop into an empty cell below.
Keep rotating planks and unscrewing bolts until all bolts have fallen into empty cells.
If a bolt is blocked by another bolt, nut, ring, or rope, rotate the obstructing plank first to clear the path.

Game Features

Rotate wooden planks to realign bolts, nuts, rings, and ropes in a 2D grid.
Multiple bolts per plank, each requiring a clear path before it can be unscrewed.
Empty cells beneath the board serve as landing zones for unscrewed bolts.
Obstacles include nuts, rings, and ropes that block bolt movement until planks are rotated.
Level progression introduces increasingly tangled arrangements of hardware pieces.

Tips & Strategies

Rotate planks one at a time and observe how each rotation affects the positions of nearby bolts and obstacles.
Focus on freeing bolts that have the fewest blockers first, as they often open access to more bolts.
If a bolt seems stuck, check whether a nut or ring on a neighboring plank is obstructing its fall path.

Frequently Asked Questions

What happens if I tap a bolt that is blocked?

Nothing — the bolt will not unscrew until all obstacles (other bolts, nuts, rings, ropes) are cleared from its path. Rotate the obstructing plank first.

Can I rotate a plank multiple times?

Yes, each tap rotates a plank 90 degrees. You can rotate any plank as many times as needed to align bolts with empty cells.

What counts as a 'free' bolt?

A bolt is free when its downward path to an empty cell is unobstructed by any other hardware piece — no part of another bolt, nut, ring, or rope overlaps its fall line.
