Artisanal Sudoku, Volume 9

Quick programming note: I plan to launch a paid version of Artisanal Sudoku sometime in the next few months, with benefits including more puzzles, full access to the archive, and hints. In order to give a sense of what the hints might look like, and potentially get some feedback, I thought I’d start including them now, at least for the tougher puzzles. But only until the paid version launches…
