Screw Nuts - 3D Screw Puzzle

A 3D puzzle built around unscrewing parts

Screw Nuts - 3D Screw Puzzle is a 3D puzzle game for Android in which each level is an assembly held together by screws. The goal is to take the screws out of the assembly, and the developer, Easetouch, lists it under games as a casual title.

The developer says each level brings a new challenge, so the puzzles get harder as you progress.

Rotating the object to find matching screws

Each object can be turned in three dimensions, and you rotate it until the screws you need are visible. Screws are matched by colour, so the work is in spotting which screws belong together before you start removing them.

The listing names rotation as the main action in every level.

Removing matched screws and taking parts apart

When a matching set is found, you unscrew it from the assembly, which breaks the object down piece by piece. The core loop is rotate, match and remove, repeated across levels that the developer describes as increasingly complex.

Casual colour-matching play for all ages

The game carries a USK rating of All ages, and its mechanics are simple to state: turn the object, match by colour, remove. That makes it suited to people who enjoy colour-matching or 3D puzzles without needing any particular background in them.
