This is an optical illusion whereby the coils can appear to be closer or further away than they really are. Presented by Muroi as a supplementary souvenir at IPP13.

Nice little puzzle by Sam Cornwell, made by Eric Fuller from granadillo and curly maple.

A pair of Gregory Benedetti puzzles made by Puzzlewood,de . I offer them as a pair simply because their outward appearance is identical. The puzzles are quite different!

Terrific puzzle by Greg Benedetti beautifully realized in wenge, bubinga and leopardwood by Eric Fuller.

Designed by Greg Benedetti and made by Puzzlewood, this puzzle's disassembly begins very easily then becomes much more complicated!

A Ronald Kint-Bruynseels design this time with a little modification by Eric Fuller. The slightly angled grain gives the puzzle a kind of twisted appearance but this is merely an optical illusion.

27 piece Walnut 3D jigsaw over 20 years old. Comes with plastic case but the bottom is missing. This was made by a small UK puzzle company called Trench Enterprises. It was run by Kevin Holmes who made a range of wooden puzzles. Kevin Holmes is unfortunately no longer alive, and his company has closed.

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...

Designed by Marc van Kreveld + Theo Geerinck, produced by Puzzlewood.6 pieces make a cube of 8 smaller cubes. 11.5cm x 11.5cm x 11.5 cm

Constructed this time with three nicely contrasting hardwoods, and holly splines as a nod toward the 2005 edition. I have to say I'm very happy indeed with how these turned out. Extremely precise and with a great feel and look. The joinery is shouldered and reinforced across each length, making this a very sturdy puzzle that you won't be afraid to solve.With two possible solutions, the paperclips interlock to form a beautiful sculpture once solved. At 14 moves, finding the the solution to this w...

Anansi's Maze, designed by Pavel Curtis. This lovely acrylic puzzle was a good bit of fun to solve. Placing "all 12 pieces flat in the tray" is really not a puzzle at all; but putting them in so that the letters don't overlap is tricky. Then, figuring out the hidden message is also tricky. That leads you to the third puzzle. Anyway, the puzzle was a little journey of solutions, and quite satisfying; took somewhat less than an hour to solve. Impressive design from 2009.
