A 3-piece burr requiring 8 moves to remove the first piece.  Puzzle is sturdy and a bit tight on some of the moves.  This was Eric Fuller's exchange puzzle at IPP26 held in Boston in 2006.  The puzzle is complete in its original plastic bag as presented at IPP26, complete with solution and Eric's business card (at the time).  I will ship within the US at insured priority mail pricing (around $10), and am happy to ship overseas at cost (The minimum cost for an overseas package is $15.50...

I am selling Bolt Action and Unsafe Deposit together because I feel they should be experienced together. These two remarkable puzzles offer so much sequential discovery for the price. These are must haves in my opinion. Shipping will be calculated after auction ends. 

This work was designed as a KCG Christmas present for 2019. From the KCG website:Based on “8 BURR” (K-9) produced in 1982, it was finished in a Karakuri box. The box is assembled like an interlocking puzzle, and a mechanism like Karakuri box is built in the lid. It doesn't fall apart, so it looks like a kumiki, but it functions as a Karakuri box.Payment is accepted through PayPal.  The buyer will pay the exact cost of shipping once the buyers location is declared.  Please inquire with any...

Very hefty, high-quality metal packing puzzle. Excellent condition with a few surface imperfections that don't affect the solve in any way.From CD: Feed The Monkey is the first packing puzzle from the (in)famous Two Brass Monkeys collaboration. The goal is simply to feed all the bananas to your monkey so that none are left sticking out of his or her mouth. The solution is deceptive and unexpected, and I think for a first try they have nailed it!The construction of this puzzle is impressive. S...

Sold out copy from a very limited release of this unique SD puzzle. It's not extremely challenging, but a fun solve with a really cool a-ha moment.From the Friendly Works website:Wet Hair is the first ever sequential discovery puzzle from Friendly Works! Made from layered, laser cut acrylic, your task is to find the coin, which will prove trickier than you might expect.

Topless Box was my contribution to the legendary Apothecary Puzzle Chest. Topless is an unusual challenge; with two lids and no top, how can it be opened? The solution is tricky and will surprise you. Originally released in 2012, we found strong demand with our re-release last year and decided to make one more batch for newer collectors who have been unable to find a copy.This batch of Topless was constructed from a plank of very nice striped Sapele which shows a lot of shimmer via chatoyance in...

BurrBon is an utterly unique Interlocking Burr Puzzle. What could be better than a six-piece burr? How about a six-piece burr inside another six-piece burr? There are several ways to build the inner and out burrs separately, but only one possible configuration assembles them together. The interaction between inner and outer pieces is what makes this an extraordinarily difficult puzzle.The construction of BurrBon required just the right balance of tolerances to allow the inner burr to move smooth...

Brace Yourself is a 6 piece burr puzzle made from Rosewood. Fit is excellent. Your choice as to whether you want it assembled or not. It was originally unassembled. Comes with original documentation and solution. It is a challenging puzzle so if you’re a burr-ginner, I suggest the assembled option! Description Frans had the stated object of making a six piece burr which looks slightly different than you are used to. To give you a heads-up we have at least given you a photo of the assembled p...

This unusual 3 piece burr has an unusual solution. It was made to look hand finished, so the 'rough' look to the puzzle was as it was sold and is intentional. Only 5 of this puzzle were made.The puzzle can be send assembled or diassembled and it is fairly heavy for it's size, so shipping will reflect this.

I love this puzzle so much, I somehow collected two of them and figured someone else should get the chance to enjoy it. This is a very popular, sold out packing puzzle with an excellent ah-ha moment.

A reproduction from a turn of the century promotional piece during the presidential election of 1896.This puzzle design is almost equal to Hanayama's cast laby puzzle, produced around 1996.The main differences are the text and the colour.It comes with a solution sheet that also describes the background of the design.The goal is to navigate the double sided maze on one of the two rings and ultimately seperate the two parts.

From Rob's Puzzle Page - "An enigmatic 1" square circuit board with a red LED in the center and a membrane button on each of the four top edges - marked 1, 10, 100, 1000. Insert the coin cell battery and the LED starts blinking. What does it all mean?"
