puzzles/auxiliary/spectre-gen.c, branch master My sgt-puzzles tree Loopy / grid.c: support the new Spectre monotiling. 2023-06-16T18:15:47+00:00 Simon Tatham anakin@pobox.com 2023-06-16T17:30:53+00:00 a33d9fad02d6319cb9061119a6165ed5493a3ba5 This uses a tile shape very similar to the hat, but the tiling _structure_ is totally changed so that there aren't any reflected copies of the tile. I'm not sure how much difference this makes to gameplay: the two tilings are very similar for Loopy purposes. But the code was fun to write, and I think the Spectre shape is noticeably prettier, so I'm adding this to the collection anyway. The test programs also generate a pile of SVG images used in the companion article on my website.
