Tap the Bolts.
Clear the Plates.
Restore the Factory.
Step up to the mini assembly line. Tap colored bolts in the exact right sequence to unscrew them, releasing stacked, powder-coated metal plates into their matching acrylic sorting bins.
The Machinist's Core Loop
A deterministic, highly satisfying logic puzzle where every move counts and every clear feels physical.
Tap to Unscrew
Inspect the overlapping plates. Tap a visible, colored bolt to unscrew it. Watch the satisfying friction sparks fly as the threads release!
Manage the Bins
Removed bolts must go into matching Clear Acrylic Sorting Bins. If your bins fill up before you clear a plate, the assembly line locks up.
Watch the Clack
When the final bolt is removed, the heavy metal plate cleanly swooshes off the board with a deeply satisfying, metallic "clack."

Machinist FAQ
No! We designed the game with "Extreme Depth Cueing." By exaggerating ambient occlusion shadows and using a crisp, cool studio rimlight, the layers are instantly readable without needing to mess with a 3D camera.
Absolutely not. We explicitly banned "physics-chaos sandbox play." This is a logic puzzle. When you remove the last bolt, the plate uses a "canned" animation to cleanly and predictably swoosh off the board every single time.
If you run out of tray slots before clearing a plate, the board locks. However, you can use in-game currency or watch a quick rewarded ad to unlock an Extra Bolt Tray Slot, saving your run instantly!
