RELEASED:5.27.2013PRODUCED:42 CopiesDESIGNER:Logan KleinwaksCRAFTSMAN:Eric FullerMATERIAL:Walnut, Maple, CherryCOMMENTS:f you like solving one six piece burr, how about two at the same time! With a difficult level 18.6.3 solution, this puzzle is not for lightweights! Tricky and entertaining, and displays very well once solved. Three different woods used for aesthetics and also to give the solver a chance (this puzzle would be exponentially more difficult in solid wood). Logan also designed a fou...

He's a smooth talker with a complex personality, and that describes this box pretty well. I brought the apearance of the box full circle to the first one, with the slight difference that the veneer runs a different direction.I promised that the boxes would be ...

RELEASED:1.31.2015PRODUCED:49 CopiesDESIGNER:Eric FullerCRAFTSMAN:Eric FullerMATERIAL:Cherry, Peruvian WalnutCOMMENTS:Ages ago I made a couple of smaller puzzle boxes with mitered corners and reinforcing splines. Appropriately enough, I called them the "Splined Boxes". I have always had a couple other ideas for that particular joinery format, so I decided to make a couple more in the series. These next two will be the Splined Box #3 and #4. The fourth is available as a reservation with a $25 dep...

RELEASED:2.13.2013PRODUCED:40 CopiesDESIGNER:Yavuz DemirhanCRAFTSMAN:Eric FullerMATERIAL:Sapele / CocoboloCOMMENTS:When I saw this design (along with "Begonia") I knew immediately I wanted to make it. Blurring the line between a packing puzzle and an interlocking puzzle, the goal is to construct the 3x3 cube inside the box. Tougher than you might imagine since the opening is only 2x2. The solver must figure out the proper piece orientation as well as the order of insertion. Tricky but not insane...

RELEASED:4.15.2015PRODUCED:38 CopiesDESIGNER:Olexandre KapkanCRAFTSMAN:Eric FullerMATERIAL:Yellowheart, CherryCOMMENTS:This is probably my favorite puzzle of the update, and I spent a lot of extra time and attention on it. It's whimsical for sure, but still an impressive level 10 solution. The Yellowheart and Cherry offset each other for that pleasing chicken look without all the annoying chicken poop everywhere. Or do they?I'm very proud of the construction techniques used in this puzzle. The Y...

RELEASED:3.27.2013PRODUCED:54 CopiesDESIGNER:Stewart CoffinCRAFTSMAN:Eric FullerMATERIAL:Oak and WalnutCOMMENTS:Double Cross was Tom Rodgers exchange puzzle at IPP 29 in San Francisco. Designated #240 by Stewart Coffin, it looks fairly simple with six thicker sticks intersected by six thinner sticks. Solving it is anything but, as the angles are very confusing and you always end up with that one piece that won't fit. I'm delighted with this puzzle, it's a heck of a lot of fun. Difficult enough t...

Mr. Coffin himself doesn't seem to have many records of it, stating in his book that he only made a few and had no records of ever selling any copies. I'm not sure how Allen revived the design, but I'm glad he did because this is a very interesting puzzle. Thanks to him for giving me permission to make ...

This work was designed as a Christmas present for 2015.This is a developed version of “Bean Bag Drawer (RF36)” that was designed in 2013. The goal is to find the hidden deep inner space of the drawer. You should move the four white plates in correct order. Of course, it’s not quite that simple to open – you also need to consider other ways it all fits together. When you feel the spring start to shift, you will know that you have successfully found the inner box.
