A nice 5-piece design by Yavuz Demirhan crafted by Brian Menold from beautiful woods, the names of which I could only guess at so I won't.

It is purge time for fivesinatras - I have to let go of some puzzles to free up some space (and recoup some funds); my collection is focused on take-aparts, so I am listing some excellent limited release puzzles from other puzzle categories."While Haym Hirsh has become known to my customers as the designer of the inelegant series of puzzles, he has now busied himself coming up with a few different types of designs. This one, a rather difficult packing puzzle. I spent 3 weeks trying to solve this...

This was one of two of Laszlo's entries into the IPP Design Competition and a TOP TEN Vote Getter. You know when Laszlo makes designs a packing puzzle that it will be a good one! I think this one has a difficult to find Aha! moment, making it even more satisfying. This puzzle has some rather close tolerances so it may not be for high humidity conditions.Shipping Cost and Handling Fees (4.5%) Will be worked out once the Auction has ended.I will combine shipping on multiple items if reqired.

A very interesting a tough interlocking/route finding puzzle from IPP28 in Prague.Multiple challenges and a great collectors piece.Offers welcome.

"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 ...

this is Allen Rolfs lovely exchange puzzle at IPP38.it allows you to make the classic 6 piece diagonal star with just about every combination of notches on the sticksthe box has two extra spaces - this is intentional!many challenges on the inside lid

Up for auction is another brilliant brain teaser out of Frederic Boucher's fin - the DEKO & BOKO puzzle.

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...
