Dic Sonneveld was a designer of mathematics-based puzzles.  One of his efforts resulted in "Dutch Crosses," six piece burrs that could not be solved by computer.  Perennial IPP Puzzle Exchange participant Dirk Weber took one of Dic's designs, modified it so that it would have a unique solution, and used the resulting burr for his exchange puzzle at IPP23 held in Chicago in 2003.  The pieces were manufactured by the the great Josef Pelikán prior to his most untimely passing.  The puzzle come...

MINIMA COINMAFB x 翁 CollabFrederic Boucher and I have collaborated on designing this coin release puzzle! Material: 3d-Printedsize: 103.24 x 72.16 x 18.00mmShipping:  

Rock-It Burr. Purchased from nothingyetdesigns.

This little beast requires a maximum of 35 moves among the Grooved 6 Board Burr series to remove the first piece from the assembled shape. During the solving process, you may feel that the pieces are no longer interlocking together, but none of the pieces will come apart in a simple way. A few pieces tend to partially rotate and become very unstable especially around 14 moves from the assembled shape but there seems to be no shortcut solution for the first piece using rotational movements. It ...

I bought this puzzle box direct from the Hakone Karakuri Museum in 2023 when I visited Japan. It's such a lovely puzzle box using Iwahara's great panel shifting style solution. It was released in 2017 and I bought it new. So it's not readily availablevia Karakauri themselves.This one doesn't work the same way that you may think like the other KCG sliding panel boxes (eg: Secret Boxes). It's movement has great surprises in store, and there is also an alternate solution to this puzzle box.The qual...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!Don’s Dilemma is an Interlocking Cube, so no rotations are involved. While the move count is fairly low, it's easy to get confused on how to put the pieces together. Good thing the wood colors help indicate how everything is meant to come together! It's also a very early puzzle made by Brian Menolds, so the fit is fairly tight. Once the pieces are together, it's not easy to get the pie...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!Slow Waltz isn't a tic, but rather an Interlocking Cube where there is no rotations involved with the solve. Don't be fooled though! The lack of rotations doesn't make this puzzle a trivial solve: https://cubicdissection.com/products/slow-waltzLong story short, I'm selling several dozen Turning Interlocking Cubes on behalf of a collector. Due to health complications, they don't have ...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!Halny is a tic with clever rotations where one can't just rotate a piece and move on. No it involves sneakiness such as half rotating a piece to insert another piece before the rotation can be finished. It's one heck of a wild tic. Be careful with following the provided link, since a solution is included with the displayed puzzle: https://puzzlewillbeplayed.com/444/HalnyLong story short,...

Dial case is an awesome SD from Juno. It looks simple from the outside but once the solve begins you’ll realize how much there is hidden inside. Juno has a really cheeky prize at the end and in my opinion the reset is even more enjoyable than the solve 

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!NervousTIC lives up to it's name by making the solver nervous on how they're meant to get the last few pieces in! It feels like some force will be needed or at the least be very tempting, but there is always a solution avaliable where only the gentlest of touches are needed.Long story short, I'm selling several dozen Turning Interlocking Cubes on behalf of a collector.

Tube It In, by Wil Strijbos, the early metal version. I acquired this from Wil in 2004. This was made from steel by Wil, the precursor to the wooden version made by Eric Fuller. It's small; about 2" in length. Unlike the wooden version, there is no magnet holding the puzzle together, so be careful when removing it from the box, or you'll have little square steel tubes all over the floor.US postage is $7.35 and international postage is $29.95.

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!Caged TIC #1 is tricky since it's not just about putting the pieces together into a cube, but also doing it within a cage. Which makes sense since it'd be trivial outside of the cage. But the solver must resist smashing the cage apart! This puzzle doesn't need a hammer to be solved.Long story short, I'm selling several dozen Turning Interlocking Cubes on behalf of a collector. Due to h...
