3D Bolt Master™: Screw Master®

What you do in 3D Bolt Master

3D Bolt Master™: Screw Master® is a casual puzzle game about taking apart layered 3D structures. You remove screws and bolts in the right order, sort matching colors, and clear pins without blocking the moves you still need. It suits players who prefer short, hands-on puzzles over timers, combat, or complicated story modes.

Simple rules, careful choices

Each level presents a different arrangement of nuts, bolts, and panels. Rotate the object to inspect it from different angles, then work out which piece can move safely. Matching colors helps organize the board, but the main challenge is planning around limited openings and blocked parts. The controls are easy to understand; solving a crowded arrangement is where the thinking comes in.

• Explore puzzles from multiple 3D angles.
• Unscrew pieces in a workable order.
• Match colors while clearing pins and obstructions.
• Use visual patterns and icons through the color-blind option.

Good for quick, repeat sessions

The game can be played offline, making it practical for a commute, a waiting room, or a few spare minutes without a connection. Levels gradually give you more pieces and tighter arrangements, so it works both as a relaxed sorting game and as a light planning exercise. Daily tasks and limited-time challenges add reasons to return, without changing the basic screw-and-sort loop.
