Free 3D Screw Puzzles — Nut & Bolt Sort
Screw Puzzle is ArcadeOwl's home for the nut-and-bolt sorting craze — the biggest hyper-casual puzzle trend of 2025-26. Each level racks up threaded bolts stacked with jumbled coloured nuts; only the top nut moves, and it only fits an empty bolt or its own colour. Lock three of a kind and the bolt clicks shut. Simple to grasp, devious to master: every unscrew reveals something new, and the spare bolts are your only breathing room. All 120 levels across four tiers and two dozen workshop themes are proven solvable by a solver using the exact rule you play with, each with a fair turn target. Free, instant, one-finger play with undo and global plus daily leaderboards.
