Screw Master 3D: Pin Puzzle
Screw Master 3D: Pin Puzzle is a 3D disassembly puzzle. Each wooden or metal plate is held by colored screws. You unscrew a pin only when it is not covered by another plate, then the freed plate can drop or slide away. Hidden screws under a plate stay locked until that plate is gone. You finish a level when every screw is removed and the stack has collapsed without leftover pins.

How to play
Gameplay
- 1
Tap a fully visible screw — if a plate sits on top of it, it will not turn.
- 2
Remove screws of one plate until that plate drops out of the stack.
- 3
Watch color groups: some levels only let you store a few screws of each color on the side rack.
- 4
Clear the top layer before hunting screws on layers below.
- 5
If the rack is full of one color, unscrew a different color first so the rack can empty.
FAQ
Questions and answers
Is Screw Master 3D: Pin Puzzle free?
Yes. Unscrew the 3D stack in your browser at no cost.
Do I have to download Screw Master 3D?
No. Play the embedded pin puzzle here.
Can I play Screw Master 3D on my phone?
Yes. The portrait 3D view is meant for tapping screws on a phone.
Why doesn't a screw I can see rotate?
A plate still overlaps it, or the color rack has no slot for that screw's color.
How do I beat a Screw Master level?
Remove every pin so all plates fall away. Anything still bolted means the level is not done.
