Brand new puzzle in its original packagingA trick opening puzzle where you have to free the spark plug. There is a hint on the puzzle.The solution is not included with this puzzle. Please note that this is a rather large puzzle that weight around 500g 

The Yin Yang Ball is a fairly rare and unusual item, and the manufacturer didn't call it a "puzzle" when they sold it. As a puzzle, it is extremely simple; the four inner rods contain magnets, and keep the two outer shells together. It's a bit of struggle to get it apart, but not terribly so. It's an oddity from the year 2000, originally sold at www.yingyangball.com, which no longer exists. 

25 moves to remove the first piece. Movement is very smooth.

One of the rarest puzzles in my collection. Scott Peterson's simple but elegant puzzle. Beautifully crafted. Time for someone else to enjoy it.

This is an early version of Rocky's pin'n'nut. Made in 1993. It has extra pins on the bottom nut and is maybe 50% larger.Definitely a collectors edition. Solution sheet included.

From Eric Fuller's description:The "Topless Box" is my contribution to the project. I originally was only going to make enough for the submission, but got pretty excited about the design once it was finished, and decided to make it a larger run. I've seen a fair number of boxes and this one has what I believe are some unique characteristics. Unfortunately I can't show much detail of the inside of the box without giving away the workings. I can say that the box has two lids, and neither a top nor...

From cubic dissection.com:Tom emailed me this design a while back and kind of downplayed it. I thought it was a brilliant idea. As usual, I was right :-) This 5x5 cube is a shell with a hollow interior. Inside the cube is another 2x2 cube, minus one unit. The internal cube interacts with the shell in a maddening way, interfering with what should be a straightforward disassembly. There's even dead ends and false solutions. The large hole in the shell is there so you can poke your finger in and ma...

A nice puzzle that is not so easy to find now.

I picked this puzzle up second hand as part of a larger puzzle group and unfortunately the Cigar was missing from the puzzle when I acquired it.There are some very minor marks to one side of the puzzle that I assumehave arisen subsequent to purchase - I've been unable to get a clear picture of them and they are barely noticeable they - are most visible on the last picture with the black background.Eric's original description was as follows :"This final installation of the Havana's box is the "Br...

Eric's Description: This puzzle is a joint effort between Pit Khiam Goh and Eric Fuller. Pit designed the B-Box, which is a cross between a secret-opening type of box and a burr - inspired by Super-CUBI but with a much simpler mechanism. It also has an insane level 135.9.2 solution! The panels slide frictionlessly and end with a satisfying click...this is a really nice puzzle.Once you conquer the 135 moves of the B-Box you will find another, entirely separate puzzle box waiting inside. Called th...

As per Mr. Fuller:This design was inspired by the interior of the previous box I made, the Reactor Box. The final interior box was held in place by a couple strong magnets, and felt like a button when pushed. It made me think about the things I could do with an apparently simple box that just had a button to push. I like to take advantage of people's assumptions, and everyone has them when it comes to a button! So I set about thinking up designs...I came up with a lot of ideas. Therefore, this w...
