The cartesian wallet returns for a limited time! These sold out a while back but I had several requests for them so I decided to make another batch. This time I was able to find a nicer, more supple leather that's also slightly thinner. Frankly these are tedious to make so I'm doing this one batch and once they're gone they're gone - I don't plan on making more in the immediate future. Here's the story on them...Akio and I were having a beer during IPP in Prague in 2008 and he showed me his inte...

This puzzle looks similar to the Alcatraz puzzle, but is much larger, and more difficult to solve.  Very well made and because of its size, easier to work with toward a solution.  The object of the puzzle is to free the golf ball from the cage.A solution comes with the puzzle, but be advised, it is a video on a VHS tape.  Puzzle also comes with 3 pages from the filed patent, which offers insight into the internal workings of the puzzle.

Three pieces, uncomplicated, with a fun level 15.3 solution. The keyring serves two purposes...you could actually use this to hold keys, the pieces aren't going anywhere (May not want them being rough handled in a purse or pocket though). Additionally, the chain blocks a second solution...so, remove the chain and see if you can find another way to put the pieces together. This will probably be shipped disassembled unless I am able to put it back together over the course of the next wee...

Although the category is in "Take Apart", Oskar's Paperclips are very much a put together puzzle and the 3 pieces interlock together. This set is absolutely stunning. Find one of the two solutions and it displays like a piece of art. this is what Cubic Dissection wrote about them: "Another classic by Oskar van Deventer, the Paperclips puzzle is rarely made, and for good reason. The length of the sticks and small surface area for overlap at the edges makes it very difficult to construct. Each cor...

A true classic and an inspiration for other puzzle makers. Lunatic Lock by Gary Forshee. I do not know who made this copy but I would lean toward Bits an Pieces. Solution sheet included. Overall it is in nice condition with surface cosmetic marks here and there including 2 very minor dings on the bottom. Nothing that effects the solve or the display when displayed sitting upright on its bottom.A little about myself and the puzzles. I am a solver / collector. I try to collect various types of puz...

"Boxy by László Molnár is a unique packing puzzle concept. You must pack the five simple pieces into a clever box with a rotating and connected top/bottom panel. Joined by a dowel, the top and bottom move together and therefore limit access to the interior. As the box fills with pieces, the movement of the lid is increasingly restricted. Despite multiple possible configurations, you can assemble only one in a particular order. Boxy is a fun, challenging puzzle.I'm thrilled with how this puzzl...

This is a beautiful little treat! A 3 piece burr; How hard can it be? This little puzzle is small enough to fit in your pocket and big enough to hurt your brain.

This is a "must have" for every collector. They don't often go up for sale or auction but even when they do they are tough to get. Lots of rotatio...

Tube Maze was George Miller's first 3-D printed puzzle. George writes: It was designed by Oskar van Deventer and is a very typical Oskar maze where the piece traversing the maze needs to go through a parity change (be flipped) before a solution presents itself. Another feature of all Oskar puzzles is that the goal is obvious. Here it is to simply remove the red ring.It is a beautiful worthy of being called a work of art in its own right.
