Rotothorpe #1 is a really cool design in my opinion. I have always loved this type of puzzles. I know many people do not but this has been designed by Andrew Crowell so you know there will be a rotation or twist or something to confound you! Since this puzzle ships with a piece left out of the assembly the total moves of 17 is not applicable to your predicament. The Walnut version is made the same way as the padauk and purpleheart versions but with wooden dowels and not brass pins. There are over 20 brass pins epoxied into each puzzle for strength.
