If you were misled by other books with trivial Sudoku puzzles labeled "difficult" or medium puzzles called "hard," we feel your frustration. What is "easy" for one person can be a serious challenge for another and categories are not precise.

Because there is no official Sudoku grading standard, you have no way to compare puzzles from different authors. For example, a medium puzzle in one book can be called hard in a newspaper or in a book by a different author.

To help you confidently select puzzles at the level you want, Puzzle Books Plus is committed to using a consistent grading standard for Sudoku books by Kat Andrews. We determine difficulty by the logic techniques needed to solve the puzzle. Look inside the book to see the logic techniques used for Hard Sudoku.
