Bolts and Nuts

Getting stuck on a challenging level in Bolts and Nuts (or Wood Nuts & Bolts Puzzle) is a common experience for many players. You look at the board, there are no empty holes left, the pieces won't budge, and you’re faced with the dreaded "No Moves Left" screen.

While some difficult levels can feel nearly impossible, you might just need to adjust your puzzle-solving strategy. Here are 5 common mistakes players make in Bolts and Nuts and exactly how to fix them to clean up your board.

1. Unscrewing the Bottom Pieces First

This is a frequent misstep when tackling a new board. When facing a large or crowded puzzle, the instinct is to remove the bolts from the biggest pieces immediately to get them out of the way.

The Problem: In many level layouts, pieces on the upper layers need to be cleared before lower pieces can move freely. If a plank is layered underneath other bars, unscrewing it first won't help. It will stay trapped by the pieces above it, and you have just used up your available empty holes for no progression.

The Fix: Take a moment to analyze the board before making your first move. Identify which piece appears completely unobstructed on the top layer, and focus on clearing that one first.

2. Filling Up Every Empty Hole Too Early

In Bolts and Nuts, empty holes are your most valuable resource. A common error is moving bolts into any open hole you spot just to remove them from a specific plank.

• The Problem: If you fill up all the available empty holes on the background board too early, you risk creating a deadlock. Without free space to park the next screw, you will be forced to either restart the level or use a booster item.
• The Fix: Try to keep at least one or two holes completely empty as a temporary parking space. Before moving any screw, check if that placement will block your next logical move.

3. Removing the Final Bolt Too Quickly

It might seem efficient to completely strip a piece of all its screws right away. However, doing this without a plan often backfires.

• The Problem: When you remove the last screw holding a long bar, the piece drops instantly. Depending on the level layout, a piece may rotate, swing, or shift position after a bolt is removed. If it lands awkwardly, it can cover other critical holes underneath, making the rest of the puzzle impossible to solve.
• The Fix: Consider leaving a single remaining bolt to hold a piece in place while you clear the surrounding area. Use that final screw as a pivot point, and only remove it when the path below is completely clear for the piece to drop safely.

4. Misjudging How the Pieces Will Shift

Since many version of the game simulate gravity, pieces don't always slide straight down, they often rotate or tilt.

• The Problem: If you remove a bolt from one side of a horizontal bar, the piece will likely pivot and swing downward from the remaining attachment point. Players often overlook this movement, accidentally blocking access to other screws needed later in the sequence.
• The Fix: Before loosening a screw, look at where the remaining bolts are located. Visualize the direction the piece will tilt or slide, and ensure it won't trap other vital parts of the puzzle.

5. Using Your Boosters Prematurely

It is tempting to use a hammer or an extra hole booster the moment you feel stuck on a tricky level for more than a couple of minutes.

The Problem: Free boosters are limited. Spending them on early levels out of impatience means you won't have them available when you encounter genuinely complex milestones later in the game.

The Fix: If you hit a wall, use the Restart button first. It costs nothing and lets you test a completely different sequence of moves without wasting valuable items.

What to Do When You're Completely Stuck for a Solution

If none of the basic strategies above work, it is time to change your approach. Many difficult Bolts and Nuts levels have multiple possible opening moves, but only one specific sequence leads to a clean solution.

When a level feels truly blocked, try restarting and intentionally choosing the opposite side of the board for your first move. If you are still struggling to find the right sequence, looking up a level walkthrough video or a step-by-step guide can help you identify the exact order of operations needed to clear the trickiest puzzles.

By avoiding these 5 common mistakes, you’ll find that even the most difficult levels can be solved with patience and the right strategy!
