RAR! How could I not make a puzzle named after dinosaur sounds?! Seriously though, this is one of the most unique designs I've seen in a long while, and I predict it will sell out very quickly. An unusual seven pieces forms a very unusual L shaped burr with a unique level 9.15.1.6 solution. The mechanics are odd and surprising...overall this is a super fun puzzle that will add a unique touch to any puzzle collection.Construction of this puzzle is outstanding, with splined mitered corners and sho...

This release's cube offering is the very tricky and unique "Worm Cube" by Askerli. Each piece features concentric rings on two planes, which makes figuring out what goes where a very tricky endeavor. The level 7.2.2.1.3 solution gives nothing away. I cannot stress enough how confusing and difficult this puzzle is to reassemble. You've been warned!This copy features a mixture of various exotic hardwood species, which is unique from the cherry production copies. **********************************...

These puzzles are extras and oddballs that have accumulated in the shop.  Sometimes when we make a run of puzzles we will have a few with different woods, etc. which are too much trouble to list individually on the website.  These puzzles are all in new condition and fully functional.This puzzle features highly figured ambrosia maple from another project, which is unique from the walnut production copies.************************************************************For multiple items, combined s...

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 up with interesting variations. In ...

Another hit from the creative genius of Yavuz Demirhan. Octo cube is a six piece board burr which must be assembled within a cube construct. The cube itself is comprised of eight identical pieces which interlock around the board burr. Assembling the cube pieces in the correct sequence is extremely difficult; this is essentially two puzzles interacting to form a whole when finished. This is a very difficult puzzle! Thirty nine moves in total are required for final assembly.Construction of this pu...

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.********************...

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...
