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 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...

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...

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...

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...

Wausau '84 15-piece burr by Bill Cutler, from the collection of Dr. Benjamin Muckenhoupt. Cutler writes on his web site, "The last of the Wausau series. This puzzle requires several moves to get out the first piece."Cutler writes about the Wausau series, "I had always been interested in designing burr puzzles which are difficult to take apart. The burr shapes I had used to this point all had the same symmetry as the 6-piece burr or the 24-piece burr - mathematically there are 24 symmetries to th...
