Hexangular Jam, IPP27 Exchange, Iwahiro Design, Strijbos Exchange

Hexangular Jam is one in the series of "jam" puzzles by the great Japanese puzzle designer Iwahiro (Hirokazu Iwasawa).  This puzzle was used by Wil Stijbos as his exchange puzzle at IPP27, held in Gold Coast, Australia in 2007.  The object of the puzzle is to slide AND ROTATE the four hexagons and eventually slide the yellow hexagon out of the frame.  (The three other hexagons are too thick to fit through the slot in the side of the frame.)  This is the ORIGINAL version of Hexangular Jam, produced in Japan out of MDF.  It has since been reproduced in plastic and other woods, but this is the original version.

My copy of Hexangular Jam is as I purchased it from Iwahiro at IPP27 sixteen-and-a-half years ago.  I have never removed it from its cellophane wrapping (as evidenced in the photos).  I will include a copy of the solution to Hexangular Jam from the IPP27 booklet.  

Thank you for viewing my auction!
