Keep that in mind as you go crazy trying to solve his latest creation. Derek's half dozen is fiendishly difficult at a level 26.9.5 solution. It's so hard to solve I took pity and made the pieces from three woods so you'd have a big clue as to what goes where. I'm also shipping it ass...

RELEASED:9.18.2009PRODUCED:30ish CopiesDESIGNER:Bram CohenCRAFTSMAN:Eric FullerMATERIAL:Maple or Curly Maple or RosewoodCOMMENTS: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 difficul...

designed by Oskar van Deventer(Netherlands)number of pieces: 36difficulty rating (from 1 to 10): 9availability: out of productionThis is the BIG DADDY cousin to the Oskar's Knot 12 and Oskar's Knot 14 puzzles. Disassembly requires eight specific shifting moves in order to get the first piece out, and then another eight moves to get the next pieces out! From there, much more shifting is still needed to fully reduce this puzzle to a pile of 36 pieces. Similar to Oskar's Knot 12, the assembly proce...

Here at Pacific Puzzleworks, we have found that many people are so content just rotating the "yolk" around inside of the two "egg-shell" pieces that the do not want to even try to get them...

designed by Ronald Kint-Bruynseels(Belgium)number of pieces: 9difficulty rating (from 1 to 10): 8availability: out of productionThis puzzle is an unusual member of the Board Burr family because absolutely no shifting moves are required, yet it is serially interlocking every step of the way. During disassembly, each piece pulls directly out of the puzzle one by one, but only in a very specific sequence because each subsequent piece is locked in place by the one that comes out immediatly before it...

One of the particularly interesting characteristics of the design is that all six pieces can effectively be extended outward as much a desired without interfe...

No idea where I found this design; I prototyped it this one time. Very odd six piece burr design. One of the glued on cubies does not match (walnut). Also it's unfinished.

Quoting Eric's website: "Designed for Kevin Sadler by Jose, this beautiful puzzle displays elegantly and is reminiscent of Bill Cutler's excellent work. While not a super high level puzzle, the shape is unusual and that adds to the complexity of solving it. I used three different woods which gives a significant clue to the solver in determining which piece goes on which axis. Given that I feel this is an approachable puzzle even for the novice puzzler, which still retaining a solid challenge for...

Quoting Eric's website: "If you like solving one six piece burrs, how about two at the same time! With a difficult level 18.6.3 solution, this puzzle is not for lightweights! Tricky and entertaining, and displays very well once solved. Three different woods used for aesthetics and also to give the solver a chance (this puzzle would be exponentially more difficult in solid wood). Ships assembled. Buyer to pay actual shipping and 4% PayPal fee.

from cubicdissection.com:Tom hits it out of the park again. This tricky little construct takes a simple yet interesting cage and seven identical pieces to create a 31 move masterpiece. There are rotations, but they won't help you. There is a lot of movement, but it wont help you. There is one and only one way to get all seven pieces in to this cage...the first six go pretty easy. The seventh takes 31 very specific, linear moves. Many times a puzzle like this can be as much a dexterity assembly a...

interesting 'burr' shape.however the movement is incredibly tight, borderline unworkable... hence the unsolved pictures...
