"The Reversible Mazes by Ohno are very fun! These lattice style structures have a starting point and an end point. The goal is to maneuver a shuttle from the beginning to the end. Typical of Ohno's designs, there are a ton of twists, turns, and surprising moves. Production will be a combination of laser cutting and traditional woodwork."This is a package deal for both the small and large reversible mazes! Each solved once and properly stored in a climate controlled environment.

It also comes with the 136 minute piece which only requires around 8,000 moves to solve.It was a difficult decision to make this puzz...

The puzzle is made more difficult because you...

Description from Pluredro (Juno's) website:This is a restricted sliding block puzzle and its difficulty is extreme. Juno believes that most human beings cannot solve the puzzle without the aid of a computer. As he vaguely remember, Juno himself needed around two weeks to find one of the solutions, and the solution that he found requires more steps than the minimum movements needed to reach the goal. Each sliding piece has grooves on two sides and one of the grooves goes halfway alon...

Codex Silenda - 7 Page Book by Brady Whitney. This was so much fun. A story that guides you through the book. The goal is to open each page by figuring out the puzzle. It is in great shape and was solved twice. Included is the original t-shirt and drink coasters that came with it. You will notice some cosmetic dings were and there. It came that way. It is laser cut wood and there is a lot moving as you turn the page so dings happen. Nothing that effects the solve. From a smoke free / pet free h...
