"The Improved One Piece Packing Puzzle seems impossible. Based on Simon Nightingale’s concept, the goal is to put the square cube in the box. Easier said than done; strong magnets push it back out no matter which face you try. What next?"This puzzle is extremely satisfying to solve and even to play with. This puzzle should not be stored in the solved state as Eric has stated that this may cause the puzzle to break down over time.

Another iconic Bill Cutler design...here's what he has to say about it:For most burr shapes, such as the 6-piece burr, if you have no internal holes, then the first piece that moves will come out all the way. This is because the burr shape is 'rectilinearly convex'. This is not true for the standard 24-piece burr shape. I decided to design a 24-piece burr in which:1) there are no internal holes2) the pieces are all notchable3) many moves are required to remove the first pieceHere is the result o...

Dog puzzle made of maple stands four and a half inches high.

4x4x4 Turning Interlocking Cube by the master himself, Ken Irvine.  From 2014.  If you like Andrew Crowell's TICs, you'll love Ken's, the man who set the bar with 4x4x4 TICs that others now strive for.  With original sticker as it came from Bernard Schweitzer.Given the recent popularity of TICs and how rarely I play with this one I'd rather pass it on to others who would otherwise never have the chance to delight in Ken's devious puzzle.Final cost to the winner will be the winning bid amount ...

Up for auction is another brilliant brain teaser out of Frederic Boucher's fin - the DEKO & BOKO puzzle. We are talking about several packing challenges and almost all of them are REALLY hard...If you already own a Boucher then you know what I am talking about....Payment Options:Generally I prefer SEPA for European customers and Paypal for all others. All other payment methods may be feasible as well but this has to be agreed PRIOR to bidding with me. Please also note that there will be a handli...

The puzzle is a set similar to the Penultimate Burr with multiple problems to be solved. The set consists of a 4×4×4 cage with a 2×2 opening on each face and 14 non-planar penta/tetracubes. The objective is to fill the cage with four of the pentacubes and three tetracubes to complete a 4×4 cube. A jig is provided for testing possible solutions outside the cage, as well as a box which doubles as a display plinth for the solved puzzle. This is a difficult puzzle, with two assemblies having a...

Burr #306 is a classic. The puzzle is solid when solved with no internal voids, and comes apart into two sets of three pieces. This is not to be mistaken with easier versions that appear the same...the 306 design is arguably the most difficult of the internally solid (meaning no room for multiple piece moves) six piece burrs. Very difficult, and a great gift for that relative who thinks they're smart!This puzzle is shipped assembled.For multiple items, combined shipping is available. Simply mess...

Another very cool interlocking puzzle from the talented Mr. Jolly. Think Outside the Box has a long name and a moderate level 9.2 solution. However, there's a catch! I found this very tricky to solve and tricky to disassemble as well. Simple in concept and brilliant in execution, this is a design you Jolly well better not miss.The construction of this puzzle is very very good. The box is shouldered for strength and the pieces are notched wherever end grain meets side grain. This puzzle will be a...

Puzzle is assembled now...let me know if you’d like it shipped disassembled.   Gorgeous heavy TIC made by Eric Fuller.  In excellent condition  BioTic is a BEAST! 28 total moves and nine rotations are required to solve it. Designed by Andrew Crowell, these fascinating "Turning Interlocking Cubes" take it to the next level. Instead of straightforward linear moves, these designs require rotations during the solution process. Construction is outstanding, with shouldered joinery where side grai...

Cube Sixteen is one of Coffin's more obscure designs but is nonetheless a delightful puzzle. Five unique pieces serially interlock with one possible solution. It's much more difficult than you might expect; even disassembly can be tricky. Crafted of some of the nicest canarywood and rosewood I've found in a while, it displays well with a lovely symmetrical appearance.This puzzle is shipped assembled.For multiple items, combined shipping is available. Simply message me once you are finished biddi...

Geneva is the first new puzzle by William Hu in quite some time. Named after the clockwork mechanism that it's partially inspired by, the level 9.3.4 solution includes some very unique rotations and coordinate motions. During assembly, there's a fair amount of freedom, with a lot of dead ends to run into and circles to run around in. Geneva is a nice addition to any TIC collection.64 total copies made for sale, each signed and dated. 54 copies in Curly Ash, 10 copies in Curly Figured Ash were ma...

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.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...

from cubicdissection.comHalf Lid Box by the famous Hajime Katsumoto is a similar challenge to Obstacle Box. With only two layers and one slider, you'd think it was easier. You'd be thinking wrong in this case...while there are fewer pieces, the smaller opening necessitates rotational moves which greatly complicate assembly.Construction of this puzzle is very sturdy with shouldered edges and milled, solid pieces. This puzzle is shipped disassembled.

Two obviously related designs by Greg Benedetti.  Only two pieces in each but 1 needs 8 moves and 2 needs 7!  Be careful as, to the best of my knowledge, the pieces are not interchangeable!

Another brilliant packing puzzle by the designer of the award winning "Casino" puzzle, Harun is a tricky assembly. Six notched sticks and six small planks pack into the box two different ways. The solution is trickier than is apparent given the simple pieces.Construction of this puzzle is excellent, with a precise fit which displaces a cushion of air when the entire assembly is dropped in at once.For multiple items, combined shipping is available.
