The "Gatherings for Gardner" (G4Gs) are held every two years to celebrate Martin Gardner's legacies in the worlds of recreational mathematics, magic, and puzzles.  They are world wide gatherings of mathematicians, magicians, and puzzle enthusiasts.  The most recent Gathering was held in Atlanta in February 2024, and the next Gathering is scheduled for San Francisco in early 2026.  At each Gathering, participants are encouraged to bring small gifts, or contribute short papers, reflecting Marti...

This was my exchange puzzle from IPP32 held in Washington D.C. in 2012.  It is based on a puzzle from 1932 by the Atlantic Refining Company that was used to advertise their motor oil.  The objective of the puzzle is to place the two wooden pieces on the scoreboard to produce a 12-11 victory for the Washington Nationals.  (The second photo shows an incorrect solution to the puzzle, because the final score shown is 11-9, not 12-11.)  Note that the puzzle is made from ash, the same wood used in...

From KCG: This is an improved version of the 2013 Christmas present. It has been redesigned to emphasize the trick. The lid can be easily removed. However, the goal of this box is to get the ring out of the box. This is the smallest number of movements among the karakuri boxes I have made, but I think it helps to break the ice when a couple meets for the first time.I accept PayPal and Zelle.

ResQ is genuinely one of the coolest SD puzzles I’ve ever solved. A lot of people compare it to jammed gem based off the number of steps and tools, but in my opinion, it is much more complex of a solve with a ton of tools to use along the way.

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!HoleyTIC is considered by many to be the hardest 5x5x5 tic ever devised, if not the hardest tic ever! There's a reason why it's called "Holy tic!" and it's not just for the holes in the puzzle!Long story short, I'm selling several dozen Turning Interlocking Cubes on behalf of a collector. Due to health complications, they don't have the spare time or energy to manually sell any puzzl...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!This GemTIC is most likely one of the most beautiful tics out there with the sheer variety of woods used in its construction, and its non-cube shape makes for a difficult solve since it's not intuitive to work from corners or to "place" a piece against a flat side when looking for the final assembly. Good luck solving this gem of a tic!Long story short, I'm selling several dozen Turning ...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!Coast-in Case is a puzzle with an interesting purpose. It's a box to lock up and store 4 drink coasters. Yeah, yeah, I know that's such a terrible design. Who ever heard of being forced to solve a puzzle just to get a coaster to put under a wet glass? By the time the coaster is freed, the glass would be dry!This is a ~20 step SD puzzle box that contains 4 drink coasters. The idea was o...

Hello prospective bidders! Come and enjoy the pretty pixels of whichever puzzle is being listed for this page!TriumviraTIC is, as fitting it's mouthful of a name, most likely the hardest of all 3 piece tics designed by Andrew. It has the longest solve sequence compared to the rest, and is trickier to solve even compared to tics with 4, 5, 6, or more pieces involved. Just because a tic has only 3 pieces doesn't mean it will be a trivial solve: https://woodwondersonline.com/products/triumviraticLo...

Snappy Burr is one of the best fidget friendly puzzles I have ever done. It lives up to its name with very satisfying "snapping" moves which gives such a tactile pleasure to perform. Once the initial trick is solved, it comes apart fairly easy, and the main challenge of the puzzle is to then figure out how to reassemble it. All in all, I consider it a relatively gentle, but unique puzzle, and it comes with a solution sheet if any help is needed.This is the latest and third version of Snappy with...
