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 corner is reinforced by a shoulder joint, then sanded flush and further reinforced with a full length spline. This is a very time consuming process, but is the only way to ensure the strength and rigidity necessary for this work of art.The result is worth the effort. With two possible ...

2-in-1 is a twelve piece interlocking burr with a unique solution and a couple challenges; the first puzzle is to figure out what shape it makes, and the second is to make that shape. Ingenious design using full notches makes finding a solution more difficult, as the open spaces concealed in the puzzle allow more false starts.This puzzle is shipped disassembled.For multiple items, combined shipping is available. Simply message me once you are finished bidding and I will send an invoice.*********...

Rick sent me this design a while ago and initially, I wasn't going to make it...all those holes are incredibly time-consuming to drill. He stepped in and helped with the drilling, so this is a true collaborative effort between designer and producer. Logical Progression is a very unique cube. With only one solution which must be accomplished with serial assembly, it seems at first look that this puzzle will be a trial and error nightmare. However, the puzzle is designed such that scrutiny of th...

Another brilliant design by Mr. Eyckmans, "Sloot" means "ditch" in Dutch, a reference to the slots on the sides of this unque puzzle. Taking the six piece board burr to another level, Sloot features a very difficult level 16.6.4 unique solution. The interplay created with asymmetrical stick dimensions, the inner tabs and the outer slot means this puzzle moves entirely unexpected ways! Shipped assembled, disassembly alone is a formidable task.This puzzle is shipped assembled.For multiple items, c...

This spooky sequential discovery puzzle by Rex Rossano Perez is a very enjoyable puzzle to work on during Halloween, a horror movie, or the night of Friday the 13th!It comes with hidden mysteries where you need to search for and find tools to release the ghost unfairly locked up within its prison so it can venture forth and terrify the world once more!When playing with this puzzle, I recommend to do so over a tray because the tools have a habit of falling out and it would be very easy to loose t...

Alexander has done it again with yet another difficulty packing puzzle! This puzzle will require some out of the box thinking (pun intended).I attempted this problem by first working on how to get all of the pieces into the box without worrying about filling the and - holes. I first made several cubes as potential assemblies, but there was very little space to move in the box. So I went back to the drawing board to practice by putting in only two pieces at a time to observe how t...

Martin Raynsford has taken the standard jigsaw puzzle and combined them with space filling fractals for a completely new type of puzzle. You dump out the pieces and then struggle to figure out which piece goes where which is harder than it looks. Usually the smaller pieces will fit into the same place as the bigger pieces. So just because you can find a place that fits a piece, doesn't mean it's the correct spot. It's very well-crafted since the when the pieces are perfectly positioned, they fal...

This one is a nice slot maze like burr. Little description from Pluredro site:----If you would like to have an interlocking burr puzzle that is something different from others that are widely available on the markets, this is it. As you see in the images, the burr puzzle has a very unusual appearance. The six light-colored pieces are held by the internal core piece by fitting T-slots and T-rails. There are a total of eight pins (cap screws) mounted on the sides of the pieces and those...

A very interesting design, it combines a simple packing puzzle with a very unconventional box. Each layer of the puzzle has a sliding plank which must be properly positioned and manipulated to progress the solution. With many assemblies outside the box but only one inside the box, this is ...

Seven pieces pack into a square box with a smaller square opening. The first several are easy...then the uphill battle begins. With six like pieces and a mirrored seventh, one would expect multiple solutions. Unfortunately there is only one solution, a fairly high level X.X.X.X (Level given by re...

Five simple pieces fit into an attractive cage through the opening in the acrylic. The solver quicky realizes that there simply isn't enough room to accomplish this...to find the solution you'll have to make a discovery!Construction of this puzzle is outstanding, with a very precise fit.

A seemingly incredibly mathematically complex puzzle in mechanical puzzle form, Isaac's Iris was based on an idea by world-renowned computer science giant Donald Knuth and used by perennial puzzle exchange participant Stan Isaacs as his exchange puzzle at the 21st International Puzzle party (IPP21) held in Tokyo in 2001.  The object of the puzzle is to arrange the sixteen pieces to form a disc --- resembling the iris of an eye or  of a camera (as in photo 2, which is ...

B-Lock padlock puzzle by Boaz Feldman.The original rubber key ring was replaced with a metal one.Original description by Boaz Feldman: B-Lock is an original lock puzzle, designed by Boaz Feldman (the son of Dan Feldman, the designer of the DanLock). B-Lock is a two stages puzzle. When you first examine the lock, you'll notice that you can't actually insert the key into the keyhole... It's BLOCKed! To unlock it, you'll really need to think outside the box. The specific trick of this lock puzz...
