Try a hint before opening the full solution
These are original Crafty Puzzles strategy hints based on the documented objective and mechanism; they do not reproduce the manufacturer’s step-by-step solution.
Hint 1
Start by identifying anything that behaves differently from the apparently rigid gear layers; the official description confirms a detachable element is part of the mechanism.
Hint 2
Listen and feel for small magnetic changes while rotating or inspecting the assembly rather than applying force to the gears.
Hint 3
Once the magnetic constraint is released, keep the layers aligned and separate them gently so you can understand how the mechanism resets.
