About Nuts and Bolts: Screw Puzzle

Where water sort forces you to pour colours between tubes, Nuts and Bolts: Screw Puzzle pivots to a spatial-removal logic: you click bolts to unscrew them from holes, and each extracted bolt can only come from a board that still has a clear path. The one divergence is that you are not matching — you are disassembling. Bolts are not poured; they are clicked free, and the constraint is not colour on colour but geometry: a bolt exits only when the hole above it is empty, demanding a forward-thinking order rather than a matching sequence. The board shrinks one fastener at a time, and every click either clears a path or dead-ends the solve.

Think you can clear the board? In this clever puzzle, you strategically move bolts between holes to dismantle the wooden planks. Each satisfying click removes a bolt, freeing up space and bringing you closer to a clean slate. The challenge is figuring out the right order to move them—one wrong step can leave you stuck! It’s a simple but addictive test of logic, perfect for quick sorting fun.

How to Play Nuts and Bolts: Screw Puzzle

Click a bolt that is not blocked by another bolt above it to remove it from its hole.
After removing a bolt, the hole becomes empty, potentially freeing bolts on lower rows.
Continue removing bolts one by one, always choosing an unblocked bolt.
Clear every bolt from the board to dismantle the wooden planks completely.
If you click a blocked bolt, you cannot remove it — find a different bolt that is accessible.

Game Features

Spatial removal puzzle — each bolt can only be clicked if nothing blocks it from above.
Wooden plank boards hold bolts in staggered rows, creating layered accessibility constraints.
Satisfying click feedback with each bolt unscrewed and removed from the hole.
Progressive difficulty as deeper boards have more interlocking bolt placements.
Clean, minimalist visual design focused on bolt-and-plank geometry.

Tips & Strategies

Before clicking, scan the entire board for bolts with no bolt directly above them — those are your only current options.
Removing a bolt from the top row often opens access to multiple bolts in the row below, so plan which path to open first.
When stuck, trace each column: a bolt is removable only if every hole above it is already empty.

Frequently Asked Questions

What happens if I click a bolt that is blocked by another bolt above it?

The game will not remove a blocked bolt — you must click an unblocked bolt to proceed. The click will have no effect on a blocked fastener.

Is there a penalty for clicking the wrong bolt?

There is no penalty for clicking a blocked bolt — it simply does not unscrew. You can click freely to test which bolts are accessible without losing progress.

Do the wooden planks affect which bolts can be removed?

Yes, the planks hold the bolts in fixed positions, and only the bolt's vertical obstruction (another bolt directly above) matters — not the plank itself.
