Clamp is a very fun puzzle. When Tim originally sent it to me I didn't see the brilliance. After thinking about it I made up a prototype and immediately knew I wanted to offer it to my collectors. For such a simple assembly, it's surprisingly tricky to take apart! Sliding the halves back and forth and hearing the satisfying click of the magnets as they align the box is addicting. Careful or you'll never put this one down...Construction of this puzzle is outstanding! Very precise movement with a ...

I've been in correspondence with Logan for a while about several designs. He was investigating the concept of interlocking burrs with pieces that also compose a packing puzzle. After he swing several ideas and designs by me, I told him I'd really like something that had a unique solution both as a packing problem as well as a burr problem. It took him a while, but wow did he come through!Two Burrs in a Corner is an extraordinarily difficult puzzle. To start, The burr pieces will pack into the co...

This puzzle was my exchange gift at IPP this year. Designed by Yavuz, it's a simple but fun interlocking distraction, with a level 6.3.3.3 solution.

Ok, this is the wicked difficult contender in this month's update. It has a unique level 14 solution with a TON of false moves and dead ends. Honestly I could barely get this little sucker apart without the solution, much less back together. As the name implies, the four ring pieces spiral around the central column of stick burr pieces. Very attractive, VERY difficult.Each puzzle constructed of fine walnut and Padauk. Fit is very good! An excellent puzzle and I'm pleased with how it came out.***...

While this is not an extraordinarily difficult puzzle, it's nonetheless fun and enjoyable. The concept is unique and a bit whimsical; dovetailing three stick burr pieces and three board burr pieces into a simple symmetrical burr shape. With a unique level 2.4 solution, assembly is not very difficult. Oddly I found disassembly trickier; the tolerances are accurate such that everything must line up perfectly and in a somewhat surprising way. An interesting little puzzle I'm glad I made.Constructed...

From Mr. Puzzle's blog post found here:  Condor's Peeper "Jack Krijnen has invented a number of different 18 piece burrs in the past few years but this one stood out from the others. The puzzle has 29467 possible assemblies.To assemble the puzzle in this symmetrical colour combination the puzzle has a unique solution. This solution is a level 62 disassembly; this means that it will take a minimum of 62 moves in exactly the correct order to remove just the first piece. The puzzle requires a tota...

Tim has been doing some very interesting work with regular burr pieces interacting with loose elements inside cages. I wanted to make one of his designs but there were several to choose from and it was a tough choice. I eventually settled on Event Horizon as a good representative of the concept. Four standard burr pieces dance around with a single cube in a box. The box has an unusual opening in the top and bottom, and hidden protrusions inside. The level 20.4.6.7.3 (whew!) solution is very diff...

This tricky puzzle by Osanori has an interesting appearance as well as an interesting solution. The two halves of the frame create a maze internally which changes state as you slide the pieces back and forth. The internal pieces dance around, moving in and out and about each other until finally they (hopefully) find their final resting spot with a symmetrical solution. Given a unique level 20.2.5 solution, this could not be called a simple puzzle, but neither is it hopelessly difficult. The obvi...

This attractive piece of art is also a dang tricky puzzle. Four sticks interact with a straightforward cage in vary non-straightforward ways. The unique level 24.6.3 solution means what it says - this puzzle's not joking around. Figuring out which piece goes where is only the beginning, since some of them switch around during assembly. Order at your own peril - I'm shipping this assembled in the spirit of friendship - craftsman is not liable for any lost sleep!Construction of solid wood througho...

Rail Box looks like just another caged burr at first glance. It's only after playing with it that the genius of the design is apparent. Four identical vertical pieces dance around the two longer horizontal pieces to create a unique level 18 solution. Not only do you need to determine the position, but orientation becomes important as well. A nice challenge for the seasoned puzzler, yet approachable for the intermediate / beginner.************************************************************For mu...

Made in the same fashion (and intended as a companion to) 2014's "Rail Box", Nine Theta takes the same piston concept even further down the road. While the solution is a couple moves fewer than the Rail Box (15.3 instead of 18), it's more confusing due to the increased number of pieces. This is a damn difficult puzzle, even for the seasoned collector!Construction of this puzzle is excellent, with through cage joinery, milled solid pieces and bevels all around. Fit is dead-on.********************...

From Stewart's Ap-Art book:"Twelve hexagonal bars are held together with 12 dowels in a symmetrical assembly.There are 2 versions.

STC #244 Double Cross hand crafted and signed in pencil by Stewart Coffin.Double Cross was Tom Rodgers exchange puzzle at IPP 29 in San Francisco. Designated #240 by Stewart Coffin, it looks fairly simple with six thicker sticks intersected by six thinner sticks. Solving it is anything but, as the angles are very confusing and you always end up with that one piece that won't fit. I'm delighted with this puzzle, it's a heck of a lot of fun. Difficult enough to challenge an experienced puzzler whi...

Are you ready? No. You're not ready. This puzzle is a BEAST.Puzzler's Cage was designed by Junichi Yananose in 1999 without the aid of a computer. He describes it as “crazy hard”. The puzzle has more interlock than should be possible, with half of the stick ends captive in notched perpendicular pieces. Even with instructions, assembly is a daunting task.We used three different woods to give clues for solving. The beautiful tones of Bubinga, Schedua and Black Palm ensure this will hold a priz...

"Oskar's Matchboxes has always been one of my favorite designs. In terms of originality, appearance and overall appeal, very few puzzles come close. The five dissimilar pieces consist of an outer box and inner tray cleverly glued together. The goal is to assemble the pieces so that every tray is contained inside a box. With only two solutions, this is quite tricky!Oskar’s Matchboxes is a very time-consuming puzzle to make, with all pieces constructed using the same shoulder joinery that we use...

This is the Scacco F.R. Opal Puzzle Chess Set. It was designed by the Italian architect, designer and puzzle maker Franco Rocco. The original version, made in 1977, was called 'Scaccomatto' and made out of solid brass and chrome plated. Several different versions of this chess set have followed since then, this one is the most affordable to date.Info below from the Puzzle Museum:This 4th version will be limited to an edition of 1000 copies (without certificates).
