STC #244 Double Cross hand crafted and signed in pencil by Stewart Coffin.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 to challenge an experienced puzzler whi...

Similar to the wildly popular 4L design, Box Rebellion is a tricky multiple-step packing puzzle with a single solution. The four identical pieces must be packed into the box but are blocked by an odd-shaped acrylic slider over the top which only allows one side of the box to be accessible at a time.  The solution includes multiple rotations.For multiple items, combined shipping is available.

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?"

Gorgeous and well crafted puzzle by Dee.

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...
