Tenchi is a brilliant anti-gravity packing puzzle named after a Japanese word that translates to both "Sky" and "Land," the goal is to pack the pieces into the frame so that the puzzle can be lifted and rotated without any part falling out.

There are over four thousand possible assemblies, but only one unique assembly locks the pieces. While challenging, Tenchi is not impossible; analysis and experimentation provide enough insight that you may find the solution using critical thought.

We used nine different exotic woods for the individually beveled pieces (Ash, Wenge, Canary, Rosewood, Birdseye Maple, Purpleheart, Paduak, Goncalo Alves and Marblewood). The frame is solid Cherry reinforced by half-lap joints concealed by the angled corners. Fit is precise, with just a bit of room to account for dry shop conditions.

80 copies are available. Each puzzle is signed and dated. Tenchi ships assembled in an unsolved configuration.

Our work is handcrafted to very precise tolerances and must be kept within the range of 40-60% relative humidity at all times. Failure to do so may cause inoperability or permanent damage.

Finally solved!

The number of potential assemblies can be intimidating and threatened to keep this one in my solving backlog for a long time. But after a very reasonable logical aha, you'll find the number of possibilities drop sharply to achieve the intended goal! Spent at least a couple days on and off so close I could taste the coming victory. :)

Novel puzzle concept

This puzzle is gorgeous and well made, my only confusion is that the goal of the puzzle is not clear. On this page it is stated that the puzzle needs to be "rotated" without any piece falling out. But rotated how? Every possible way? On the piece of paper that came with the puzzle it says it must be "rotated upside down". This is a bit clearer, but having solved the puzzle I can see that it is not entirely accurate either. Puzzle will be played describes it as "antislide for up and down direction" which is the most accurate description of the goal.

A real challenge

A real mind twister. I figured out where the pieces need to go....just gotta figure out how to get them there! Genius design and masterfully crafted as always.
