Nuts and Bolts: Screw Puzzle

Unscrew every bolt in the right order before the whole contraption collapses—sounds simple, but one wrong move and everything falls apart.

I'll admit, I loaded this up expecting a mindless tapping game. Instead I got a surprisingly tense little logic puzzle. Each level plops you in front of a tower of plates, brackets, and threaded rods held together by an assortment of bolts. Your job is to strip the whole thing down piece by piece. The catch? Some bolts are load-bearing. Yank the wrong one and a chunk of the assembly comes crashing down, often taking the level's goal pieces with it. What got me hooked was the physical feel of it. Bolts have actual thread directions—some unscrew clockwise, others counterclockwise, and a few are reverse-threaded just to mess with your muscle memory. You'll hear a soft click when a bolt is finally free, then watch the plate it was holding shift slightly. That little wobble is your warning: this next move matters. I failed level 14 about eight times because I kept ignoring a subtle sag in the top bracket. When I finally stopped, looked at the whole structure, and planned three moves ahead, it clicked. That's the game—not reflexes, just patient mechanical reasoning. Definitely one of those 'one more level' time sinks.

Look for bolts that only clamp one loose piece—those are safe to remove first. If a plate starts to tilt or sag after you remove a bolt, don't pull the next one from that area yet. Reverse-threaded bolts will strip and jam if you keep turning the wrong way, so watch the little arrow indicator. Pause before you tap and read the whole structure from top to bottom; gravity does the rest. If you're completely stuck, restart the level—the ordering sometimes resets to a less chaotic starting state.
