Four wooden squares with plastic pegs. These can be put together in 3 different solutions, as shown on the problem sheet. I don't know who made this or where I got it from or the actual name of it. Got it maybe about ten years ago.

Brian's Description: The popularity of the 4C Vortex that I produced a few months ago, led me to this gem. The Flat Vortex is a simpler version of that design without as many rotations. Four pieces have to be removed from the frame. It’s still quite a challenge though. I had one customer contact me who said that they don’t actually come out, they can only be rearranged! After I stopped laughing, I sent him the solution.

Jerry's Description: The goal is to re-arrange the 5 pieces and change the #8 to a #0. Saying "abracadabra" would certainly help!Although this year's design bears some resemblance to my entry at last year's IPP competition, the #69, the Magiq#8 is totally different in terms of the solve. My design was expertly crafted by Tom Lensch and consists of exotic woods comprising walnut, holly, shedua and yellowheart. Construction, fit and finish is excellent and I particularly liked the perimeter trim ...

Eric's Description: With the invention of the NOS (New Old School) puzzle series, Gregory took the six piece burr format and turned it on its head. The only thing more noteworthy than the uniqueness of the series was how difficult they are to make. When he sent me the plans for them a year ago, I turned him down because it just looked like a nightmare to manufacture. I wasn't wrong...BUT...Gregory came up to me at IPP this summer and let me play with a couple three D printed versions and I was h...

RELEASED:8.14.2014PRODUCED:44 CopiesDESIGNER:Goh Pit KhiamCRAFTSMAN:Eric FullerMATERIAL:Rosewood, Ipe, Walnut, Bubinga, Paduak, Maple, AcrylicCOMMENTS:Pit sent me this design and I really liked it. It's a tricky packing puzzle that uses a new type of motion. With five identical pieces (but different wood types) and an acrylic cover, it's a lot of fun to play with and figure out. Moderately difficult, you can feel comfortable handing this off to a non-puzzling friend. Fit is very good, should not...

RELEASED:11.3.2015PRODUCED:39 CopiesDESIGNER:Goh Pit KhiamCRAFTSMAN:Eric FullerMATERIAL:Maple, Walnut, Yellowheart, Paduak, Bubinga, AcrylicCOMMENTS:Another one by Goh Pit Khiam, Fusion is the successor of RetroFit. As you would expect from how tricky RetroFit was, Fusion takes it to another level. The goal, to fit the five polyominoes into the partially covered tray, is MUCH trickier than it looks. Here is what Goh has to say about it: This is a redesign of my Crossroad puzzle. In that puzzle, ...

RELEASED:6.18.2015PRODUCED:46 CopiesDESIGNER:Terry SmartCRAFTSMAN:Eric FullerMATERIAL:Walnut, Bird's Eye Maple, AcrylicCOMMENTS:I'm trying to include at least one interesting packing puzzle in each update, and the A-Pack absolutely overdelivers in that regard. The concept is unique and brilliant, and I'm very glad I made it. There are two sliding shuttles which are captured in the acrylic frame. The goal is to pack the pieces completely in, and it's very very difficult. Right off the bat you're ...

RELEASED:4.15.2015PRODUCED:39 CopiesDESIGNER:Jerry LooCRAFTSMAN:Eric FullerMATERIAL:Maple, Acrylic, Various Exotic HardwoodsCOMMENTS:I like *some* packing puzzles, and this one made the cut. It's a set of pentominos and a simple box, yet there is only ONE solution to packing them all in. A truly extraordinary achievement! I interpreted this one with a lot of panache, using 12 different woods for the pieces (Canary, Bubinga, Yellowheart, Peruvian Walnut, Paduak, Wenge, Shedue, Mahogany, Ipe, Boco...

RELEASED:4.15.2015PRODUCED:20 CopiesDESIGNER:Oskar van DeventerCRAFTSMAN:Eric FullerMATERIAL:Various Exotic HardwoodsCOMMENTS:Every five years or so I make a small batch of this puzzle. I'm proud to be able to offer it at a very low price this time due to economies of scale with the Matchbox Play Six. Oskar's Matchboxes has always been one of my favorite designs. In terms of originality, interesting appearance and overall kickassness (yes I just made that word up) very few puzzles come close. No...
