Woods used are Bird's Eye Maple and Kingwood. Overall, a nice addition to any collection. Puzzle has been played with only once and is in like new condition. Buyer to pay actual shipping charges.

This was my exchange puzzle at IPP31 in Berlin. The goal is to assemble the three pieces into a "symmetrical shape". This puzzle can be sent assembled or unassembled, your preference. Definitely more difficult unassembled, as you have to figure out what the final shape is.The second photo shows the actual puzzle for sale. The first one is the last one sold which is virtually identical.

Here is William Strijbos' description of this puzzle: I designed this puzzle around 1984 and it was my first puzzle box. At that time I produced only 6 of them (for Jerry Slocum – Nob. Yoshigahara – Dick Hess – Edward Hordern – James Dalgety). Now I have reproduced this design in an improved, metal version (previously it had been made of Formica or a similar material). The challenge is: Try to get the Rod out. No Tapping required – No Magnets – No External Tools.

To solve Snake Ball, the two donuts have to be pushed into each other. A spherical pin at one donut moves inside the grooves of the other and vice verse. All grooves are cut in a helical pattern around the donuts, so the two donuts always rotate simultaneously, which is very confusing.

Both mazes are completely different, and ...
