While I’ve been featuring a lot more puzzle types this year, I often get requests to go back to having more Sudoku. While my focus for many months has been organizing the 2014 Sudoku Grand Prix, now that that work is mainly done it seemed a good time to revisit the style here. So the deficit of that style won’t continue for much longer; we’ll have some classic puzzles, but not on consecutive days as that might be too many classics in a row. Even odd folks like us can appreciate a good puzzle where nothing is repeated, neighbors.
