Four very different and unique International Puzzle Party exchange puzzles, all designed by the great Dutch puzzle inventor Oskar van Deventer.
4D --- Oskar's exchange puzzle from IPP23 (Chicago, 2003). This is a very colorful sequential movement / route-finding puzzle, requiring 55 moves to solve. Two discs require rotations, and two "half" disks require horizontal back and forth movements.
15 Holes of Golf --- Jan L. Grashuis' exchange puzzle from IPP23 (Chicago, 2003). This theme-based route-finding puzzle was designed through a joint effort of Oskar and the late great Markus Götz. The goal is to "get the yellow golfer through the 15 holes to the arrow-shaped clubhouse."
Fragile Fractominoes --- James Dalgety's exchange puzzle from IPP26 (Boston, 2006). This "fragile" puzzle was beautifully laser-cut in MDF by Peter Knoppers. The goal is to fill the tray with the ten pieces. Please see the instructions for a description of how Oskar designed the pieces.
Boston Subway --- Dave Rossetti's exchange puzzle from IPP26 (Boston, 2006). This is another route-finding puzzle, a circuit maze made of a sandwich of 5 layers of clear acrylic with a tiny magnetic disk trapped inside (with horizontal and vertical channels in each level, and "elevators" through which the disk can be manipulated between levels), and a magnetic wand that can be used to drag the disk along the maze. The goal is to bring the disk to from home to work (trivial), and then back to home FROM work.
All four puzzles are as they were received at IPP23 (2013) in Chicago or at IPP26 (2016) in Boston, all with whatever original paperwork may have accompanied them. I will provide copies of the
solutions to the puzzles (from the appropriate exchange booklets) for those puzzles that did not come with solutions.
I will ship within the US at insured priority mail pricing (likely from between
$11.00 and $17.10, depending on postal code). I am happy to ship
internationally at cost, but I cannot always guarantee that overseas
packages can be insured or tracked.
Thank you for viewing my auction!
