  1. I love the shape of this one! Usually noticing quads in a sudoku is way too hard, but here the geometry gives you lots of natural pairs and quads to think of as groups. Well done!

    1. Thanks !

      When I create extra-regions sudoku, I like to use at best the logic induced by the shape of regions. In this sudoku, it was really interesting to see that the L-shape regions induced some nice matches between group of cells.
