Dovetail Burr is our follow-up to the Japanese Wood Joint puzzle we released last month. Both are part of the series that Frans designed nearly 20 years ago. Inspired by traditional Japanese woodworking joinery techniques, Dovetail Burr was Frans's IPP 20 Exchange puzzle.Dovetail Burr remains an utterly unique interlocking board burr concept despite its age. The presence of matched dovetail joints forces each pair of pieces on a given axis to interact with the other. This innovation creates a di...

With the invention of the NOS (New Old School) puzzle series, Gregory took the six piece burr format and turned it on its head. The only thing more noteworthy than the uniqueness of the series was how difficult they are to make. When he sent me the plans for them a year ago, I turned him down because it just looked like a nightmare to manufacture. I wasn't wrong...BUT...Gregory came up to me at IPP this summer and let me play with a couple three D printed versions and I was hooked. These look li...

Pair Dance is a fun little distraction with a level 14 solution. It's not nearly as difficult as that may sound since there are only two pieces. Approachable and interesting, I'm glad I made this little gem!Each puzzle is made of solid exotic woods, beveled and finished. Fit is just right, not too tight nor loose.

The "BonBon" packing puzzle by Frederic Boucher is just a ton of fun. The set of five tetrominos must be fully inserted in the rectangular box, and there is only one very specific way to do it. The solution requires well over a dozen correct moves, including rotations.The box itself is very unusual, with cutouts in the top and sides. The acrylic top is held in place with a tricky set of shoulders resulting in a great fit which retains a solid exterior presentation.BonBon is constructed with a bu...

Bill Cutler - Helix The Burr (made by Eric Fuller, 2015) ya like tough burrs?  well here ya go. sez Eric Fuller: 'Helix the Burr is one of Bill's most interesting designs. Meant to be difficult to take apart, it's VERY VERY true to form. Disassembly is chaotic and unexpected. This is a landmark design in my opinion, and I was thrilled to make it simply because I had always wanted a copy for my collection.' sez Bill Cutler: 'This burr features the most i...

Juno (Junichi Yananose) - Tornado Burr (made by Eric Fuller, 2010) pieces rotate in concert by fours on two axes to 'open' the puzzle for disassembly.  as far as burrs go, this one's a bit of a mindbender.  i think Tornado Burr and Helix The Burr would get along famously. designed by Juno in 2007.  made from Honduras mahogany. original description: https://archive.cubicdissection.com/html/tornado.html number released: 25 Brian Young (Mr. Puzzle) made the original versi...

Depressing is a fun assembly puzzle crafted beautifully by Brian Menold of WoodWonders. "This clever little guy sold out quickly at my last release, so I decided to include more copies with this release. Can you assemble the six pieces into the shape shown? Getting started is definitely the most difficult part of the solution. You should give this one a go. Almost small enough to fit in you pocket. The tongue depressor-like pieces took quite a bit of time to make, but that was a choice I made s...
