  • $\begingroup$ Spot on, and quicker than I could have done it. Note that if you use a 'standard' polydude solver this solution does not appear. You have to allow 'off grid' AKA 'against the grain' placements. $\endgroup$ Commented Apr 5, 2021 at 5:56
  • $\begingroup$ @theonetruepath Very nice puzzle. I put it into my solver and it suggests this is the unique solution. I guess that solving it manually isn't too hard since so many pieces are on the boundary of the dodecagon, and have an obvious candidate for a boundary vertex. $\endgroup$ Commented Apr 5, 2021 at 6:16

    $\begingroup$ @JaapScherphuis Yes there are 14 sets of 8 pieces (out of the 770 dodecadudes I have on file) that tile the shape 'against the grain' only. There are 313539 sets that tile only 'on grid' and another 14 if you allow 'against the grain'. The majority have a single tiling. $\endgroup$ Commented Apr 5, 2021 at 7:12
