Six Slabs is a fun packing puzzle from Cubic Dissection. Had me stumped longer than expected. 

BonBon was way trickier than expected! Very satisfying like 4L with very restricted movements. 

New Melting Block by John Rausch is an improved version of Tom Obeirne's original Melting Block puzzle. This paradoxical 3-D packing puzzle has two unique assemblies, one using seven pieces and the other using all eight. There are two possible solutions for each assembly.The seven-piece solution seems to fill the box entirely, with little room to spare. The leftover block seems far too large to fit in the box...yet somehow, impossibly, the eighth piece does fit when the second solution is discov...

Rupture by Alexander Magyarics is a tricky space-filling puzzle. While adding the pieces into the box is not too difficult, the proper solution requires you to fill the openings completely. No gaps are allowed, and no rotations are necessary. With a unique level 6.6.3 solution, this is easier said than done!For multiple items, combined shipping is available.

This padlock shaped five-piece caged interlocking burr will perplex you with its level 13 solution. The previous lock shaped burrs we have made included a key-shaped piece; the unique interplay and accessibility of simple burr pieces make this latest offering from Tim an interesting change.Precision wood puzzles can be damaged by environmental changes.

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...

Stepping Burr is a very tricky level 10 interlocking burr puzzle. The unconventional nature of the six pieces results in some very unusual movements. Crafted from figured Ash and Leopardwood, this puzzle looks gorgeous when solved and is a fine addition to any interlocking puzzle collection.Precision wood puzzles can be damaged by environmental changes.

Missing Notch is one of Stewart Coffins more difficult assembly puzzles. The six pieces are nearly identical, with notched out centers and two angled notches on the outside. One piece is missing an angled notch, which obviates the obvious coordinate motion assembly. Can you figure out the alternate methodology?This puzzle came out very nicely, with a precise fit and a solid maple cube with magnets on each face to keep the inherently instable assembly together once solved.Precision wood puzzles ...

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...

A hard to find sequential discovery box by Peter Hajek, this is the (slightly more) sought after dark version and is number 4/30. Only 15 dark and 15 light boxes were made. The box, lock and key were a terrific collaboration brought together superbly by Peter. The following is a cut/paste from the Pelikan site (https://www.pelikanpuzzles.eu/detail/howbox-dark/). See below for the original description and a few condition comments."HOW?BOX DARKby Peter HajekWoodwork: Jakub Dvorak and Pelikan team;...

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...

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 sent me the plans for them a year ago, I turned him down because it just looked like a nightmare to manufacture. I wasn't wrong...BUT...Gregory came up to me at IPP this summer and let me play with a couple 3D p...

The only thing more noteworthy than the uniqueness of the series was how difficult they are to make.

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...

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...

Hello,i want to sell this tiny lock. Yeah you're right, that next to the lock is a lego coin. So that lock is really tiny. ;)It's made out of metal -probably brass - and has a clever solution. Unfortunately i have no idea who the designer or craftsman is.Shipping can be combined if you are winning more than one of my auctions. The shipping costs will be calculated after the auction. The buyer has to pay the shipping costs but of course no PayPal fees. :)
