U.S. Marine Corps Anniversary Puzzle BoxFrom the description in a previous CDM listing: "This unique puzzle box was a commemorative gift to the 242nd division of the United States Marine Corps. It's nicely decorated with gold inlay on the top and a metal inlayed emblem on the front."This is one of the largest boxes in my collection.  When I first purchased it, I thought it was a cigar box but I'm not entirely sure that's its intended purpose.  Regardless, it a very solid wood piece with some c...

This is a seminal vanish puzzle originally created in 1990 by Robin Debreuil from Debreuil Digital Works in Manitoba Canada --- seminal because it was an early puzzle application of Flash.  In 2010, Magic Moments With Class produced it in large hard copy format (15 1/4" x 5 3/4") as The Perplexing Puzzle Paradox.  13 characters change to 12 characters and a lump of dog poop!  The puzzle comes complete with a 4-page brochure providing classroom lessons based on the paradox.  The puzzle is in ...

From Wood Wonders - "I have been wanting to make this one ever since Alex sent me the design. He has just been producing so many cool designs lately, it took me a while to get around to it. Pillar is four pieces that must be inserted into the unique box and they fill the openings completely.I had acquired some very nice holly and wanted to set off the face of this box with it. The woods used for this box are especially nice. I really love the Pistachio wood. I managed to sang a few small pieces...

         I recently decided to make a run of these cool puzzles, they are not quite interlocking so I included a tray to display the puzzle.  Not an overly difficult design but you can certainly see Stewart’s progression over the years.  This puzzle led Stewart to one of my personal favourite designs, ‘Four-Piece Interlocking Cube’.I made several different wood varieties for this puzzle design, a few in one wood and a couple in multi-woods.They are lacquered and given a coat of Co...

From Pelikan - “2D and 3D packing problems are my favourites, especially those with only a few pieces, together with a sufficient level of difficulty. I hope you will like Pincers and add it to your collection. You do not need to create the illusion of a full cube inside (like we all do with amazing packing designs by Osanori). Just fit the three pieces below the top layer. So what is the clue here? – the shapes of the pieces and box opening. Study them well to eliminate a huge number of po...

This has been my favourite 'fidget' puzzle.  It feels so good in the hands and I can disassemble it blindfold now.  A 6-piece board burr designed by Frans de Vreugd and made by Tom Lensch it has become something of an enigma, as my limited research has shown, because this combination of woods, wenge with holly spacers and tulipwood feathers, appears to have been used almost exclusively for its big brother 'Extreme Torture' .  I have searched, without success, for a similar copy of 'Extreme To...

Designed and first released at IPP in 2009, Surround is closely related to the 3/4/5 cubes designs by Ichiro. In this case, six pieces must be used to surround the solid cube in such a way that is self-supporting. Two solutions using magnets are possible, with another "rule-breaker" solution that does not use magnets and covers the cube completely! The finished shape is pleasingly symmetrical and displays well.************************************************************For multiple items, combin...

The Pin Cubes series by William Hu are three new cubes based on a 3x3x3 structure. By including drilled holes and pins, each puzzle in the set takes advantage of this format in a different way and creates three very different experiences. Designed to be tricky in both disassembly as well as assembly, they are a new take on an old idea, and well worth a look. Pinprick (Goncalo Alves) is the middle difficulty and takes advantage of its form to include an unusual step that will amuse any solver ex...
