A copy in plastic of George Hart's IPP28 exchange puzzle from Prague in 2008.  FIRE is a screw-together tetrahedron made of two identical plastic parts.  The tetrahedron is divided in two along a helicoid surface whose axis is aligned with an axis running from the midpoint of one edge to an opposite edge midpoint.  This puzzle is VERY satisfying to play with!Note that George's original exchange puzzle was produced in nylon.  This copy is accurately reproduced in plastic.  It is available th...

Slideways by Ray Stanton and Akio Yamamoto is one of our favorite Interlocking Burrs. Three simple, identical pieces combine to form the symmetrical shape. The solution is trickier than it seems, and some struggle even after even seeing it performed in front of them. There is a tricky concept in play that must be understood; once discovered, the pieces' smooth movement is addicting. Slideways is not the most challenging puzzle, but it just may become your favorite.This puzzle is shipped disassem...

Blah Box is the result of the accumulation of ideas I had while trying to design a simple mechanism for the box containing the DDD Burr Puzzle. I wanted to make a simple trick opening mechanism for DDD, but in the end, discarded the idea because it would overly increase the price of the puzzle. I came out of the design session with some solid ideas, which, when combined, turned into a rather interesting box on their own. I was feeling rather "Blah" about my failure with DDD and decided to name t...

Bill's Binary Burr, mfg by Eric Fuller, design by Bill Cutler. This was made in 2013. Eric had a lot of issues with humidity on this particular puzzle, and , as Eric said in the puzzle description, "The bad news is that the puzzle turned out looser than I would have liked." The pieces shift around quite a bit. I went through about 5 or 6 of the "binary moves" and it seems to function okay, but the fit IS very loose. See photos. The center-piece is, in fact, about 1 mm shorter than adjacent piece...

Exchange puzzle by long-time Puzzle Exchange participant Pavel Curtis at IPP21, held in Tokyo in 2001.  The object of the puzzle is to place the 12 two-sided dominoes in the tray to form a picture of the Japanese flag.  The solution is unique.  The puzzle is as received in its original plastic bag.  I will include a copy of the solution from the IPP21 exchange booklet.  I will ship within the US at insured priority mail pricing (around $10), and am happy to ship overseas at cost, but I ...

Grote Flater and 6T Burr are both what I'm going to call fantastic "dovetail candybar" burrs from Alfons. Long sticks interact with multiple dovetails, making for a dynamic solve that I had a lot of fun with.One corner of this puzzle is a bit dented, see photo - this does not effect the solve and I only noticed it myself when photographing for the listing. I accept PayPal. Buyer can expect to pay $13 shipping domestic within the US and approximately $35 internationally. Happy to combine ship...

Six Slabs is a unique packing puzzle reminiscent of the Hexahedroom design. Six uniform "slabs" must be packed into the box, which has three openings in a non-symmetrical pattern. This is complicated by two fixed blocks inside the box. With a level 1.1.9.3.2.3 solution, Six Slabs is non-trivial to solve.Crafted from Curly Maple (box) and Wenge (pieces). Great care was taken during construction, with Wenge accents on the box corners and extremely precise dimensions. Extra attention was spent on t...
