One of Stewart Coffin's most well-known design. Surprisingly tricky considering there are only 3 pieces. The target shape is a tetrahedron made from cubes, definitely a difficult shape to visualize.This copy was 3D printed by Shapeways, it is "pocket sized" and made from ten 13mm cubes. Each piece is dyed a different color, which makes disassembly easy, but reassembly is not any easier.I have several wood copies of this puzzle, and while they are very nice, none of them fit as well as this pu...

Beautifully crafted by Scott Peterson from English Walnut and Peroba Rosa and almost impossible to assemble without the jig, which is African Blackwood. This is Stewart Coffin's design #39 and #39a and is in perfect condition.

Assemble ten identical pieces (plus a small icosahedron) into a 5 cm diameter ball. This puzzle was 3D printed by Shapeways and dyed in 5 colors by me. The core is a Game Science D20 die (included).This puzzle was designed by Stephen Chin, based on a Wayne Daniel puzzle. In 2010, the wooden version won an award in the IPP puzzle design competition. This is the same puzzle available in my Etsy store, http://www.etsy.com/shop/polypuzzles.It is difficult to achieve a good fit with these p...

For some reason this puzzle seems to "solve itself", even though it is a machined item and has no damage

Description : This non-millable six piece burr is surrounded by a cage split into two mirrored halves. Not only must the solver figure out the burr itself, but they must also understand the burr within the constrains of the cage. That alone would be difficult, but figuring out how to start with one half of the cage and put the puzzle in a state which allows the addition of the second half is the real trouble. With a unique level 17.14.9.5 solution, this is a very very difficult puzz...

Description : Astero Ball is the sphere cut of Astero. It's a 6 piece puzzle using a coordinated motion.The puzzle is made in White Strong and Flexible material.This puzzle is not really functional. I need the help of my wife to assemble it, and, for now, the not-so-tricky way to disassemble it is not functional.So the price is 1 USD for the warrior who wants to have a little pink puzzle essentially difficult because of the dexterity. Size : around 4cm Materials : White strong and Flexib...

A matched set of three puzzles in bubinga and goncalo alves in excellent condition. All pieces are interchangeable, fit perfectly and slide very easily. Presented in original packaging.

Made by Eric in 2009. From his original wording :"This is one of the more beautiful puzzles I have ever seen, and also one of the most difficult. Mr. Yananose designed this in 1999 without the aid of a computer, and it is according to him “crazy hard”. I agree with that assessment! The puzzle is incredibly interlocking, to the point that fully half of the ends themselves are captive in notches. Construction is very precise, with a nice moderate fit. Some of my finer stock was u...

Made by Eric in 2009 and in his own words :"Bram has come up with a devilishly difficult construct here. The first piece slides out with decptive ease....after that gimme, it's nine more moves before the next piece is released. A hollow interior means maximum movement, maximum confusion and minimal hints. Starting with all pieces disassembled gives very few inferences as to a solving strategy. Overall a difficult and entertaining puzzle in a small and modest package. A solid choice. ...

Ancient Key, from the Mandalay Box Company. Not an impressive fit on the pins in the puzzle. Weighs 12 oz with shipping box.

Description : This puzzle is not a classic 6 piece burr.

A chance to get one of Eric's earlier works this one made in 2008, in Eric's own words :"I'm always excited when Tom contacts me with a new design, and this one turned out to be no exception. The "Noose" in the name refers to the fact that all six pieces are contained by a 4x4 square which constricts them like a noose. A squat rectangle with a unique level 9 solution, it is very solid until you figure out the deceptive first move. After that things get interesting, with lots of movem...

Alchemy, made by Eric Fuller, designed by Brian Young. An Altekruse variant, 14 pieces, all different. Fit is very nice. Eric made 28 copies in 2012. Lovely puzzle, just not one of my favorites. Sappy maple with walnut pegs. Weighs 13 ounces with shipping box.

To save time, I'm using Eric Fuller's description and pictures (below). Puzzle was played with once, but baffled me: not very good at this type of interlocking assembly. Puzzle is still in like-new condition having been stored in an air-conditioned, smoke-free environment. Starting price is the same as Eric's release price. Buyer to pay actual shipping cost worldwide. Thanks for looking! "This puzzle is two designs in one - the cage comes with two sets of burr pieces (one a six unit len...

From cubicdissection.com:This puzzle is a derivative of Karin Von Kanel's outline burr, designed in 2001. I have been wanting to make this for a long time, but was having trouble getting in touch with Karin. Finally I ran into her at the NYPP and she heartily agreed to give me permission to make it. Initially I wanted to make the "Ultimate" level 15.1, but when I plugged it into burrtools, no solution was to be found. I started playing around with the piece sets and decided on one which had thre...

This is burr was designed by Oskar and made by Tom Lensch (in I think Mahogany)Although from the exterior it looks like a six piece Burr it takes a number of shifts to disassemble and the interior notching is quite unlike a typical six piece burr.This is a duplicate in my collection and I am setting the price at $1 no reserve in the hope the martket finds an appropriate price.Shipping will be from the UK by Royal Mail (www.royalmail.com) and the actual cost of postage will be added to the final ...
