6 identical odd shaped wood pieces form a pinwheel. This puzzle comes apart with coordinate motion but 3 not obvious steps are needed before it will open. Difficult to disassemble with a lot of movement of the pieces but it will not come apart. This is the first wood version of Bram Cohen's Pinwheel design. The previous version was 3D printed. This Pinwheel has a jamming problem so only 2 wood versions of this design were made before changes were made for another Pinwheel design without the ...

From Eric: This is a very unique and fun puzzle, and probably my favorite design of the update. The box captures six sliders which move around to form an evolving maze for the four identical pieces to maneuver. Moderate in difficulty but over the top in enjoyment! If you haven't noticed I really liked this one, assembling them all was actually a pleasure.The construction of this puzzle is excellent, with a perfect fit and very labor intensive joinery and design. While fairly simple looking, it t...

From Eric: I very much enjoyed making William Hu's "Simultaneous Maze" puzzle for the last update, so when I saw that Tamás had made a sequel using two mazes and one pin, I knew I had to make it. Vanyó's design uses an identical top and bottom plate to confuse and trick the solver. I won't say much about the solution but it's a lot of fun and not what you would expect. An excellent addition to your collection, and a must have to compliment the Simultaneous design.Construction was very time con...

From Eric: 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 while simple enough to be enjoyed by a novice.Construction of this...
