A very nice puzzle, not so complex to disasemble but not obvious, and a not so easy to reassemble even if it's not complex.George bell description :"A simple and elegant design I call : U’y Octahedron, in reference to the shape of the two kinds of planar pieces. This puzzle has been made out of wood by Tom Lensch and requires coordinate motion to assemble. Later, I found out this design was discovered over 10 years ago by Viktor Genel as the first part of a puzzle he calls Octetra, although ...

Description from cubicdissection :"The Binary Burr is a classic Bill Cutler design. It was awarded a First Prize at the 2003 IPP Puzzle Design Competition, and has been unavailable for several years. Here is what Bill has to say about it: "The Binary Burr is a burr that functions like a 6-ring version of the Chinese Rings. The puzzle consists of 21 pieces. One is equivalent to the ‘bar’ in a Chinese Rings puzzle, and six others are equivalent to the ‘rings’. The other 14 pi...

Very clever and beautiful IPP Burr puzzle.  This was an IPP exchange puzzle by Eric Fuller.  Only 35 extra copies were made for sale to the general public.  When correctly solved you will have buried inside the burr the three additional pieces spelling IPP.   The puzzle forms a traditional burr shape with each end forming a beautiful checkerboard pattern, but I only know that from photos.  I bought this before I accepted that I'm lousy at burrs, and therefore the puzzle has only been out o...

Fidget burr was an easy decision to make. A seemingly simple 3x3 cube, it's actually a five-piece interlocking burr with a level 12 solution. Three burr pieces nest inside two identical frame pieces. Disassembly of this puzzle is VERY tricky, with many false paths and dead ends.  Fidget Burr is a ton of fun and it turned out very well.Precision wood puzzles can be damaged by environmental changes.

Leontev's 205 Minutes is a masterpiece in both design and construction. So named because if you make one correct move per second, non stop, it will take you 205 minutes to disassemble. This n-ary juggernaut requires over 12 thousand moves to disassemble. Once disassembled, a reset mechanism allows you to quickly bring it to the original state with only four moves. 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...

Uri Three Bars is an unusual and beautiful interlocking puzzle. This will be our second batch after an earlier, very limited release in 2015. Dario has since improved the puzzle; the previous design was solvable in 10 moves while the new release has a level 14.2 solution.These puzzles are extras and oddballs that have accumulated in the shop.  Sometimes when we make a run of puzzles we will have a few with different woods, etc. which are too much trouble to list individually on the website.  T...

Like new. Fiendish.Description:"“Another puzzle by the amazingly prolific Osanori Yamamoto, this will, of course, require rotations. There are 4 pieces in the frame and the hole is shaped such that they can only be extricated after turning to the correct orientation. Having said that the main challenge of this puzzle is actually to find the correct linear moves to make space for the rotations to occur and working out which order to remove the pieces. The reassembly is also a challenge if you d...

Like new. Nearly killed me. Description:“The third puzzle by Osanori Yamamoto could easily be called the 'Hashtag' – 4 simple shapes are assembled on a frame in a # shape and need to be removed after arranging them into the correct orientation and position. As one would expect from Osanori, rotations are required… quite a LOT of them! This is trickier than one would expect as the sliding movement and rotation of the pieces is very blocked and requires quite a bit of planning. Eventually I...

Another brilliant design by Mr. Eyckmans, "Sloot" means "ditch" in Dutch, a reference to the slots on the sides of this unique puzzle. Taking the six piece board burr to another level, Sloot features a very difficult level 16.6.4 unique solution. The interplay created with asymmetrical stick dimensions, the inner tabs and the outer slot means this puzzle moves entirely unexpected ways! Shipped assembled, disassembly alone is a formidable task.Precision wood puzzles can be damaged by environment...

Taking the following from Eric's original listing :"With the invention of the NOS (New Old School) puzzle series, Gregory took the six piece burr format and turned it on its head. The only thing more noteworthy than the uniqueness of the series was how difficult they are to make. When he originally send me the plans, I turned him down because it just looked like a nightmare to manufacture. I changed my mind after handling a couple 3d printed prototypes. These look like traditional six piece burr...

Secret Burr is a re-release of a puzzle I made very limited copies of in 2002. Unique in that it's difficult in both assembly and disassembly, there are two locks inside the burr that interact much like Cutler's Ball Bearing Burr. Instead of steel bearings, Secret Burr uses small wood rectangles. Precision crafted of fine hardwoods, this puzzle not only looks exotic, but has the trickiness to back up its appearance.Precision wood puzzles can be damaged by environmental changes.

I'm glad to be revisiting this fun design! Originally released with limited availability in 2015, the Chicken Puzzle boasts an impressive level 10 solution and a hidden surprise.  The 2020 version was upgraded with an improved chicken byproduct retention system. Yellowheart and Cherry offset each other for that pleasing chicken look without all the annoying chicken poop everywhere. Or do they...? Construction techniques used in this puzzle are unique. The Yellowheart cage is made of only six p...
