Dr. Volker Latussek wrote about it:“I have been thinking and working on FERMAT for more than two years.

Juno makes awesome puzzles. And this one is no exception. Here is what Junichi had to say: “Although the puzzle consists of only four pieces, it requires 38 moves to remove the first piece from the assembled shape. The movements required to assemble and disassemble the puzzle are so complex that it is quite difficult to comprehend whether you are moving forward or backwards. The key of such high level burr is the stepped shape of the pieces. This feature also made the assembled shape of th...

Either or.Here’s the description from the WW’s website:“Here is how Haym described it on Facebook several days ago "Somama is a Soma Cube where the dimensions of some of the pieces have been stretched a little bit in various places. They still look normal and assemble into a solid cube (un...

On the Rocks, designed by Nob Yoshigahara, made by Toyo Glass.This was an intermediate challenge for me, compared to the other Toyo Glass packing puzzles.  The irregular pieces of "whisky and ice" aren't easy to put together, but there aren't so many pieces and when they fit, it feels right.  Great looking puzzle, and it includes the original box.-----Buyer is responsible for shipping which should be less than $10 for small puzzles (within USA, first-class).  Priority mail (and heavier puzzle...

Puzzle design by Terry Smart.This thing is nuts. Honestly when I got it, I didn’t know exactly what to expect. At first, I thought it was gonna just be put together take a part puzzle. But instead, it is in the traditional form, a burr puzzle or interlocking burr puzzle. The movements are exact and precise. And the craftsmanship is next level. I must add that one of the pieces came un-glued. So I contacted Pelikan and got the exact dimensions and burrtools file, then successfully re-glued the ...
