How to Play

Game Overview

Bolts and Nuts is one of those puzzle games that looks stupid simple until you actually play it. The whole thing is about unscrewing bolts from wooden planks to make everything fall apart, but you can only remove them in a specific order or you get stuck. It's basically spatial reasoning wrapped in a low-poly, kinda cozy aesthetic -- think wood textures and metal bolts that look like they're from a furniture assembly manual. The vibe is chill at first, then gets frustrating in a good way around level 30. What got me was how each plank feels like a tiny mechanical puzzle where you have to trace the load paths in your head before touching anything. Some bolts are obviously safe to remove, others are holding everything together and if you yank them first the whole thing locks up. There's no timer, no pressure, just you and this plank and the satisfaction of watching it clatter apart when you figure it out. The controls are dead simple -- tap or click the bolt you want, tap or click where you want to put it back. On phone it works fine, though bigger levels can get cramped. Who'd like this? Anyone who enjoyed those wood block puzzle toys or the old flash game where you remove pins to drop stuff. It's not flashy, there's no music that slaps, but it hooks you with that "just one more level" loop. My only complaint is some later levels feel like guesswork rather than logic.

About Bolts and nuts

So here's the deal with Bolts and Nuts -- it's one of those puzzle games where the premise sounds almost too simple on paper, but then you're twenty levels in and staring at a plank with eight bolts arranged in a way that feels like a personal insult. You click (or tap) on bolts to unscrew them, and the whole thing is about figuring out the right order. Screw up once -- pick a bolt that locks everything else in place -- and you're stuck. The game calls these 'deadlock' situations, and they're genuinely frustrating in a good way.

The loop goes like this: you see a wooden plank held together by bolts. Some bolts are free to remove right away, others are blocked by neighboring bolts or specific patterns. You click the ones that are free, the plank starts to creak and shift, and eventually parts of it fall away once enough bolts are out. The satisfying moment is when you pull the last critical bolt and the whole thing just collapses with a clatter -- there's a little physics animation that makes it feel real. Levels have names like 'Twisted Timber' and 'The Snag' which hint at the gimmick.

Difficulty builds slowly at first -- early levels are mostly straight lines and obvious choices. Then around level 15 you get 'interlocked bolts' where two bolts share a hole, so you have to unscrew one to free the other. Later on, there are 'rusty bolts' that take two clicks to remove, and 'trap bolts' that look free but actually lock multiple planks together. The game never throws too much at once, but by level 50 you're juggling five different mechanics at the same time.

There's no upgrade system or enemies -- it's pure puzzle box logic. The brain work is all about spatial reasoning: you're mentally tracking which bolts depend on which, and planning three or four moves ahead. On phone, you tap bolts with your finger, and on PC it's left-click to unscrew, left-click on the empty hole to screw a bolt back in -- which you sometimes need to do if you realize you've made a mistake, though the game penalizes you by adding a few seconds to your timer. Speaking of timer, there's a speedrun mode unlocked after beating the first 30 levels, where every second counts and the collapse animation gets replaced by a quick fade-out. That mode is surprisingly tense.

What keeps me coming back is that moment of clarity after staring at a board for two minutes -- suddenly you see the sequence, and your hand moves automatically. The game doesn't hold your hand; it just gives you the plank and expects you to figure it out.

Tips & Tricks

The biggest thing that tripped me up early on was thinking bolts had to come out in a specific order based on how they looked. Nope -- the real trick is checking how each bolt sits in relation to the others. A bolt that looks like it's blocking everything might actually be removable if you rotate the plank first. Rotating the view is something I ignored for way too long. It's not just cosmetic -- seeing the angles can reveal which bolts are free and which are trapped.

Another mistake I kept making was unscrewing bolts that seemed loose but weren't. Some bolts are stuck because another bolt is pinning them from below. Try clicking around to see if anything wiggles. If it doesn't, move on.

For the harder levels, I learned to count the number of bolts that need to come out before the plank falls. Sometimes removing one bolt changes the whole setup, so you want to avoid creating a dead end where a bolt is now unreachable. It's better to plan two moves ahead.

A trick that saved me a lot of resets: when you screw a bolt back in, you don't have to rush. Take a second to see if that was actually the right move. Reversing a wrong unscrew is faster than restarting.

On smartphone, the touch controls can be finicky. I tap gently around the bolt to make sure I'm selecting the right one -- pressing too hard sometimes picks the wrong target.

One last thing: don't assume the first bolt you see that looks loose is the starting point. Some puzzles have a hidden order that only makes sense after you fail once. That's fine -- just note what went wrong. You'll solve it faster the second time.
