At first glance, the Yin Yang 69 (Tai Ji 69) looks like a solid, sculptural object. Smooth, balanced, and perfectly weighted in your hand. But beneath its minimalist exterior lies a layered mechanical challenge waiting to be discovered.
Designed by Ayi Liu and brought to life through careful development by Kubiya, this puzzle moves far beyond a simple disentanglement. Each motion reveals just enough to keep you going, but never enough to make it easy.
The Challenge
Your goal is to take the puzzle apart into its core components and then bring it back together. What sounds simple quickly becomes a test of patience, spatial reasoning, and intuition.
- Multiple hidden movements
- Sequential logic required
- Unexpected transitions that reset your progress
This is the kind of puzzle where progress feels earned, and every breakthrough is memorable.
Built Like a Work of Art
Crafted from aluminum with anodized elements and reinforced with steel components, the Yin Yang 69 is as much a display piece as it is a puzzle.
It is the kind of object you leave on your desk, not just to solve, but to return to again and again.
A Puzzle You Will Keep Coming Back To
Even after solving it once, the Yin Yang 69 continues to draw you in. It becomes a tactile experience, something to explore, reset, and challenge others with.
This is not a quick solve. It is a puzzle that stays with you.
