Eric's statement that this puzzle is “extraordinarily difficult” is an understatement. He continues: “To start, The burr pieces will pack into the corner only one way. But that's just the beginning. When you remove the twelve pieces, there are 28,540 ways to construct a single burr. And only ONE way to make two burrs. Thats's right...there is a unique combination of pieces that will allow you to construct two burrs, which seems insanely improbable to me. On top of that, both burrs are high...

The puzzle has a loose fit. Please see the 2nd photo for a clearer idea.From Eric's write-up: “Construction of this puzzle was tricky. The humidity in my workshop was fluctuating wildly, so I opened up the tolerances more than I usually do to make sure the final product wouldn't bind up or get stuck. The good news is that I was successful there - this puzzle should work in all humidity conditions. The bad news is that the puzzle turned out looser than I would have liked, having perhaps .035 in...

From Eric's write-up: “This is the tricker iteration of the Quads and Rings series. Four wooden burr pieces interlock with three acrylic pieces with a level 17.2.6 solution. Definitely a step up in difficulty from the Q&R1 design; Yavuz has kind of laid the gauntlet down here! Achieving the checkerboard pattern is a second challenge.”For more details: http://archive.cubicdissection.com/html/qnr2.html

From Eric's write-up: “Every time I think I've seen it all when it comes to 4x4 cubes, someone proves me wrong. In thie case it's Mr. Hu with his excellent "Two Wheeled Cube" design. with an odd level 1.1.1.2.8 solution, this puzzle is moderate in difficulty but very high on the fun factor. The first four pieces form a shell around the heart of the puzzle; two identical "wheels" which rotate and dance around each other in a bewildering number of possble states. The meat of the puzzle is figuri...

This is a very nice box by Akio Kamei.  It is in excellent condition.  This box will be a great addition to your collection.

This sequential movement puzzle box is the improved version of the one entered in the IPP 29 Design competition in San Francisco.The Improved Pagoda is a much better puzzle in as much as it covers up "clues" that gave the solver "a big hint" on how to open it. Each box  is "signed" by Makishi.Here are some particulars about the box:Limited Edition of 40.Number of moves to open: 16Designers: Matthew Dawson & MakishiMaker: YasutoshiMakishiWoods: Red Oak, Walnut, & MapleSize: 3 inches Length by 3 ...

Six piece typical diagonal burr creating a beautiful shape. Well known Stewart Coffin design but simplified because of the colour symmetry.I made a handful of these for friends and family last year and had this one left over. Great for someone who wants an inexpensive copy of a great puzzle just to actually play with. The pieces are not perfect like a Lee Krasnow or a Peterson work, so you can get some hints as some fit slightly better in certain orientations but the errors are very small so you...

Amazing but complicated puzzle. Includes the original instructions.

Well known Stewart Coffin design .I made a handful of these for friends and family  and had this one left over. Great for someone who wants an inexpensive copy of a great puzzle just to actually play with. The pieces are not perfect like a Lee Krasnow or a Peterson work but still close tolerances and nice fit all around. Overall it displays beautifully.

The is Kamei's Bottle. A lovely and quite large puzzle. Obviously it has been damaged and repaired. That said the scratches are not very noticeable  (and most are on the bottom) and the repair work leave a perfectly, smoothly, functioning puzzle. The box is ratty but it is included.

Rail BoxRail Box looks like just another caged burr at first glance. It's only after playing with it that the genius of the design is apparent. Four identical vertical pieces dance around the two longer horizontal pieces to create a unique level 18 solution. Not only do you need to determine the position, but orientation becomes important as well. A nice challenge for the seasoned puzzler, yet approachable for the intermediate / beginner. The puzzle measures 2.25” by 1.5” and was designed by...

By all rights, this Stickman Burl Tile Puzzlebox should not exist.  Assembled from spare parts, it does not have a limited edition number, and therefore falls outside of the limited edition set.  Normally, such spare parts would be tossed.  But I, (Robert’s apprentice), just could not bear the thought of scrapping them.  With Robert’s permission, they were salvaged from their dismal fate, and given to me with the understanding that, if I put in all the required work, I could have this la...

I (Robert’s apprentice) repaired this Stickman Try-Knot puzzle box from a crate of unfinished puzzles that Rob has.  There are perhaps enough parts to assemble another 5 or so of these, but he apparently just stopped putting them together at one time.  This one was already mostly assembled, but required some attention to a few cosmetic issues in order to be totally perfect.A formal description can be seen on Robert’s website, as it is unique enough that I can’t figure how to describe...

Six Key Mine PuzzleThe Six Key Mine Puzzle was designed by R.D. Rose and won him a First Place award in the 2003 Nob Yoshigahara Puzzle Design Competition. This version was made by Bits and Pieces and is no longer being manufactured. The puzzle measures 3” across and is quite hefty in the hand. The goal of inserting the six pegs into the sphered centre will have you puzzling for some time. I do not have the solution sheet for this puzzle, but will supply a printed copy of the one that is on...
