Bolts and Nuts in 3D! is a free online logic puzzle game where your goal is to unscrew bolts from planks in the correct sequence. Every move matters – pick the wrong bolt first and you'll block yourself from clearing the board. The challenge is figuring out which bolt to remove and in what order to free all the planks without getting stuck.

Starting levels are straightforward, giving you a chance to get comfortable with the mechanics. As you progress, the plank arrangements get trickier, with more bolts overlapping and fewer obvious moves available. There's no timer breathing down your neck, so you can think each move through carefully. That said, the satisfaction of cracking a tough level in one clean run keeps you coming back. Compete with friends to compare scores and see who can complete the most levels without errors.

This game is a perfect pick for fans of free 3D puzzle games, bolt and screw puzzle challenges, and single-player brain teasers you can play instantly in your browser. If you enjoy mechanical logic games, sequence puzzles, or satisfying unscrew and remove gameplay, Bolts and Nuts in 3D! delivers exactly that. It also works great as a quick mental workout during a break. No download, no sign-up – just open it and start solving.
