Description : This non-millable six piece burr is surrounded by a cage split into two mirrored halves. Not only must the solver figure out the burr itself, but they must also understand the burr within the constrains of the cage. That alone would be difficult, but figuring out how to start with one half of the cage and put the puzzle in a state which allows the addition of the second half is the real trouble. With a unique level 17.14.9.5 solution, this is a very very difficult puzz...

Made by Eric in 2008 and in his own words : Ronald is one of my favorite designers out there. He has a talent for puzzles which are not only challenging, but also very aesthetically pleasing. Kim NoPack is no exception. Using a simple set consisting of ten pieces he has devised a puzzle which is tricky and interesting to solve. While the pieces are symmetrical (two pairs of mirrored sets plus an outlier), the solution is decidedly non-symmetrical. There are several interlock...

Dustin 1935 (Laser cut plastic, 4.75" x 4.75" x 1/4"; base is 1/8" thick, tray edge is 1/8", thick and pieces are 1/8" thick) Looks like the Fifteen, puzzle at first, until you notice that pieces, except for piece 15, are joined together in pairs. Described on page 151 of Hordern's book, who notes that are a number of ways to solve it. The designer has made the pieces sufficiently tight so that solution is possible but not via Figure 4 shown in the Dustin p...

Made by Eric in 2009. From his original wording :"This is one of the more beautiful puzzles I have ever seen, and also one of the most difficult. Mr. Yananose designed this in 1999 without the aid of a computer, and it is according to him “crazy hard”. I agree with that assessment! The puzzle is incredibly interlocking, to the point that fully half of the ends themselves are captive in notches. Construction is very precise, with a nice moderate fit. Some of my finer stock was u...

This was Akio Kamei's 2012 Karakuri Club Christmas present

Made by Eric in 2009 and in his own words :"Bram has come up with a devilishly difficult construct here. The first piece slides out with decptive ease....after that gimme, it's nine more moves before the next piece is released. A hollow interior means maximum movement, maximum confusion and minimal hints. Starting with all pieces disassembled gives very few inferences as to a solving strategy. Overall a difficult and entertaining puzzle in a small and modest package. A solid choice. ...

This is a reproduction of a tea cup that functions normally until the water reaches the dragon's mouth. After that, a siphon action causes liquid to drain into the base. Also known as a Tantalus or Pythagorean cup. See http://en.wikipedia.org/wiki/Pythagorean_cup

What Eric has said:"Markus designed this puzzle quite a while ago and I always liked the looks of it. Finally I emailed him asking if the design was free...and it was! One hitch though - there was more than one solution. I greatly prefer puzzles with a single solution, so I decided to enlist Tom Jolly to see if it could be modified into a single solution. Tom quickly determined that the original had at least 15 solutions. Both Tom and Markus subsequently went to work, both coming u...
