Ever taken apart an IKEA table and thought "this could be a game"? That's basically what this is, except way more satisfying and less rage-inducing. Wood Nuts & Bolts Screw Puzzle is a brain-training casual game where you unscrew, untangle, and dismantle wooden contraptions one bolt at a time. Your goal? Remove every nut and bolt in the right order without getting stuck. It's simple to start, but the later levels will have you staring at the screen trying to figure out which screw to tackle first.
Getting started is easy—tap and rotate. Mastering the untangling? That's where your brain gets a workout.
You start by tapping individual screws to rotate them. Once a screw is fully unscrewed, the bolt pops out and the attached wooden piece becomes free. The controls are dead simple: tap to select, rotate to loosen. The challenge isn't the controls—it's figuring out which screw to remove first without locking yourself into an unsolvable position.
Here's where the puzzle part kicks in. Wooden planks overlap, bolts hold multiple pieces together, and some screws are blocked by others. You need to slide pieces out of the way, plan your moves ahead, and sometimes backtrack when you realize you unscrewed the wrong bolt. The game also throws in traps like wood wasps that block certain screws or squirrel nuts that mess with the order.
Each level is complete when every bolt is removed and all wooden pieces are freed. As you progress, the puzzles get layered—three, four, sometimes five levels of overlapping wood with screws buried deep inside. You unlock harder stages by finishing the current one, and the difficulty ramp is real. Early levels take 30 seconds. Later ones? You'll be stuck for minutes trying to visualize the solution.
Perfect for anyone who likes logic puzzles but doesn't want the stress of a ticking clock. If you enjoyed games like Unpacking or mobile puzzle games where you can take your time, this is your vibe. It's great for kids too—no violence, no reading required, just spatial reasoning. That said, adults looking to kill 10 minutes on the bus will get hooked fast. Just don't start a level right before your stop, because you won't want to quit mid-puzzle.
It's chill, but in that "I need to solve this NOW" way. The game doesn't rush you, but you will rush yourself because unsolved puzzles itch at your brain. Visually, it's all wood textures and metal bolts—clean, simple, no flashy effects. The audio is subtle: satisfying clicks when screws come out, light background music that doesn't get annoying. It's meditative until you get stuck on a level, then it becomes a personal challenge. I found myself replaying levels just to find faster solutions.
The game saves your progress automatically in the browser cache, so you can close the tab and come back later without losing your spot. Just don't clear your browsing data or you'll restart from scratch. Performance-wise, this runs smooth even on older devices—the graphics are simple enough that you won't get lag or stuttering. Works perfectly on both desktop and mobile with no noticeable difference in responsiveness.
A solid brain teaser that respects your time but will absolutely eat it anyway.
Super responsive. Tap and rotate feel precise, no accidental inputs or missed clicks.
