Not So Simple Sudoku, Red Edition Jared Acord

With extra wide margins and a lengthy introduction, this book of 200 challenging Sudoku puzzles is great for both the intermediate and experienced player. But there's a peculiar thing about these puzzles. You may call it nonaphobia, or the fear of the number nine: the number 9 does not appear in any of the starting puzzles. This is the first book in the series 'Not So Simple Sudoku'.
