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 ...

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...

A unique cylindrical design manufactured in Cornwall England and exchanged by perennial Puzzle Exchange participant Mike Hawthorne at the 21st International Puzzle Party (IPP21) held in Tokyo in 2001.  The goal of the puzzle is to stack the six half-discs and the top and bottom discs to form a five-layer cylinder.  The puzzle is handsomely manufactured in wood, with sharp contrast between the two different woods used for the discs and the pegs.  (Note that the second...

Kevin Sadler's Description from the Pelikan Website:“I have to say up front that I am totally addicted to Alexander's designs! There is something truly special about them. He has taken the type of puzzle designed by Osanori Yamamoto and added a whole new dimension of fun to them. This consists of an Acacia box which has a plus shaped opening on the top and a minus shaped opening on the opposite side and 4 rather interesting but fairly simple shapes (made from Wenge) to be placed inside such th...

"Another of Laszlo's great packing puzzles. This just seems too easy! Large triangular openings on both sides of the box should make this one a quick solve right? Wrong! If you like packing puzzles, you should give this a try. It is also a great puzzle to hand to a novice puzzler. By looking at it they will be confident they can solve it quickly. Then you can enjoy watching their frustration grow as they fight to find a solution." -WoodWondersShips disassembled/unsolved.Size: 2.875" x 2.875" x ...

"Two puzzles for the price of one!From the amazing mind of my friend Laszlo Molnar comes these two gems. Packing puzzles with rotations are not one of my strong suits but I love these! The same box but two different sets of pieces. Each set is similar in that each piece builds on the the previous one by adding a single unit cube. But the pieces are very different beyond the first few. Two distinct and rather difficult challenges in one."  - WoodWondersShipping: $5 USA, $17 International.

Dictionary Case by Koichi MiuraPack the five wood pieces into the "case".  The box says this puzzle won "First Prize" from the Japan Puzzle Association in 2019.I won a copy of this puzzle last year, and subsequently bought copies for friends and family as stocking stuffers this past holiday season.  They were a hit!  Simple enough to be solveable by new puzzlers, but still just challenging enough to feel accomplished with the solution.  I've listed both leftovers from Christmas.  The puzzle...

Bolted 1 designed by Haym Hirsh, produced by Rex Rossano PerezPack the three pieces into the tray with the restricted opening.  Pieces should be inserted flat into the opening.  I found this to be the easiest of the three puzzles in the "Bolted" series.  All 3 had somewhat unique solutions though, and it was fun to solve them in succession. This was purchased new directly from Rex and it has been solved a few times. There are no cosmetic issues and it is in the same condition as it was when ...
