Fight Cubes are akin to an Erector Set crossed with Live Cubes.  Some puzzlers use these to build polycube puzzles seen at PuzzleWillBePlayed.  The anodized aluminum 1.5cm cubes come in Gold, Blue, Silver, and Gray.  This is a mix of all four colors from two 3x3x3 sets and two 4x4x4 sets - 182 cubes. New on Amazon or PuzzleMaster these would cost about $240.

Reticulated Cubes is a fascinating exploration of 3x3 cube puzzles with a novel twist. Each box contains nine pieces, and there are eight possible cube solutions. The goal is to organize the pieces in the box such that any three pieces in a straight line will assemble into a cube (tic-tac-toe style). The solution is quite difficult to find!For multiple items, combined shipping is available.

     This is one of two entered in IPP 2020 and was awarded a top ten vote receiver. The wood species used are canarywood, padauk, redheart, yellowheart and ebony. The unusual canarywood is spalted and transitions from heartwood to sapwood. It also features grain matching on all four corners. Of all the versions I've made, this is one of my favorites and the only one to utilize ebony.     Below is a description found on cubicdissection  Dee's widely acclaimed "Where's My Hammer?"

Are you ready? No. You're not ready. This puzzle is a BEAST.Puzzler's Cage was designed by Junichi Yananose in 1999 without the aid of a computer. He describes it as “crazy hard”. The puzzle has more interlock than should be possible, with half of the stick ends captive in notched perpendicular pieces. Even with instructions, assembly is a daunting task.We used three different woods to give clues for solving. The beautiful tones of Bubinga, Schedua and Black Palm ensure this will hold a priz...

"Oskar's Matchboxes has always been one of my favorite designs. In terms of originality, appearance and overall appeal, very few puzzles come close. The five dissimilar pieces consist of an outer box and inner tray cleverly glued together. The goal is to assemble the pieces so that every tray is contained inside a box. With only two solutions, this is quite tricky!Oskar’s Matchboxes is a very time-consuming puzzle to make, with all pieces constructed using the same shoulder joinery that we use...

Description by Brian Pletcher :"The goal of this puzzle is to use the eight dark pieces to make an S inside the frame. I fiddled around with this one for a bit, but didn't have much luck. I have a tough time with these more abstract puzzles where you don't know quite what you're supposed to be doing. Eventually I gave up and looked at the solution, and it is pretty good! Perhaps I would have gotten it if I stuck with it a bit longer: it is tricky but not impossible."It was one of my ...
