I got this Revomaze new and never solved it so the original certificate should still be inside.From the Revomaze website:Crafted from anodised aluminium and nickel plated brass, this is the original classic of the Revomaze family. Don’t be fooled by that, with a solve time of around 5 hours, this puzzle can be very challenging. The V1 Blue is designed to help develop your mazing skills, the core contains a static progression maze you can neither see nor touch. You will need to use the power o...

"This ingenious burr was designed by Junichi in May 2007 with "head and hands; no computer". Junichi had the idea for a multiple rotational movement but did not get to finally apply it to a puzzle until he came up with the Tornado Burr.People often ask puzzle designers "What was going on in your head to design this puzzle?" What was going on in Junichi's head when he designed the Tornado Burr? Visualising things going up and down and back and forth at the same time is one thing, but things going...

This 3x3 with planks and cubes may look familiar, but it's got some tricks up it's sleeve. I dont want to give too much away, but generally everything proceeds as normal up to a point...then some serious oddity occurs (NO force required!) With several congruant pieces, you'll solve it the first time to get it all back together, then probably a couple more searching for the piece placement which yields a symmetrical grain pattern.Made with air dried walnut and various species, each puzzle is uniq...

This clever puzzle shows major design chops. Using four identical, simple pieces and a cage, Yamamoto created a level 9.2.5 beauty with only one solution. Fun to solve, a nice half hour challenge for the serious puzzler. The top and bottom is made from mitred Bubinga component pieces, replete with clever notching to facilitate the inset cross braces. A fine cage if I do say so myself.> Each piece signed and dated; ~30 copies made for sale. Ships assembled.

Like William Hu's "Simultaneous Maze" puzzle , Tamás had made a sequel using two mazes and one pin. Vanyó's design uses an identical top and bottom plate to confuse and trick the solver.An excellent addition to your collection, and a must have to compliment the Simultaneous design.The cage connectors are shouldered and reinforced by lateral connectors. The sliding internal pin has a pair of magnets which keep the slider centered once the puzzle is solved, a nice detail which keeps the puzzle f...

Elena's Burr by Aleksandr Leontev and made by Eric Fuller. Somehow, I accidentally bought two of these, so this is the spare. My starting price is a bit less than Eric was selling it for ($49). It's a very nice puzzle, but I don't need two of them. Weight is 10 oz with packaging, so shipping outside the US is $22.50, less for Canada.

The Goal of the puzzle is to remove the ring.The solution is connected with the design appearance so its a nice hint to find slowly what to do. This puzzle Won the 1st prize in the International Puzzle Competition 2011 IPP31 in Berlin

No Holds Barred, Laszlo and Menold. This is another puzzle where I somehow ordered it twice without realizing I already had a copy. So, here it is. This is a tricky assembly puzzle; I'm a little embarrassed by how long it took to get the pieces in the box; there's a diagonal-cut half cube interfering with the assembly at the entrance. It was quite fun to solve. Weight is 11oz with packing, and shipping outside the US would be $22.50 (less for Canada). Yes, our postal service is extortionate.

Phred's Phenomenon, by Fred Armintage, made by Bernhard Schweitzer. It's advertised as a 4x4x4 hollow cube, but in fact it has a solid 2x2x2 cube in the center! If you like, you can assemble it hollow, or not. Weight is 14oz with packing, and shipping outside the US would be $22.50 (less for Canada). Yes, our postal service is extortionate.

A wooden 15 puzzle. This has been heavily abused and gouged by some idiot with a pencil, wood-burned, and partly sanded. Worst condition of any puzzle I've ever seen. On the other hand, it's also a fairly unique "15" puzzle with Japanese marquetry. And it's all there. You can have this poor, beat-up puzzle for a buck, if you need to temporarily fill a hole in your collection. I'm not sure where I got this from. This will be mailed in a bubble-mailer, with packaging that's 2 oz. I will not ship o...

Parcel Post packing puzzle, Constantin. Laser cut. Sadly, the tray design is so loose that it allows for false solutions (like the one in my photo). I always thought, "hey, what's the big deal. This one wasn't so hard." Turns out I was wrong. Weighs 7 oz with packaging. Shipping outside the US is $13.50, a bit less for Canada.

#49 of 100This is a hefty aluminum puzzle with a very special lock. No force, no banging, no centrifugal moves. The object is to retrieve several items inside the puzzle, undo the lock, and then return everything to its original state. Very interesting mechanical design.The reason why this puzzle was titled "Pleasure and Pain" was because, in its original configuration, it was possible to get completely stuck. Solution included. Emergency key to get unstuck (which I purchased from Strijbos ...

One panel of this lock is tight.From Puzzlemaster.ca original description:Made from solid metal, this Trick Lock is more complex than it appears, and unlike regular locks, a key is not the only answer. The hidden mechanism is deceiving and requires a more careful inspection to unlock it. These locks are hand made, there are slight variations in each lock. These are replicas of ancient Indian locks. They are made to look old but are brand new.
