Uhrwerk – Intermediate Rotating Gear Puzzle by Siebenstein-Spiele

Uhrwerk is a clever mechanical-style puzzle that blends rotating motion, timing logic, and precision alignment. Crafted from layered wood and acrylic by Siebenstein-Spiele, this compact puzzle challenges you to think several moves ahead as each adjustment affects the system as a whole.

Your objective is to set the gears in motion and manipulate the rotating spinners — each featuring carefully placed missing notches — until both clock faces are perfectly synchronized and set to 11:55. What appears straightforward quickly becomes a thoughtful exercise in sequencing, timing, and patience.

Why You'll Enjoy It:

Uhrwerk is ideal for puzzlers who enjoy hands-on logic challenges with moving parts. Rather than packing or sliding pieces, this puzzle rewards careful observation and controlled adjustments. Its intermediate difficulty makes it approachable while still offering a satisfying “click” moment when the clocks finally align at 11:55.
