Black Belt Sudoku by Michael Rios
Taking a page from karate - another Japanese art - each title in the series is graded by colour: White Belt for easy, Green Belt for medium level, Brown Belt for hard, and Black Belt for the super-tough solvers. Each title also contains 300 puzzles.
Michael Rios is the author of the top-selling first series of Belt sudoku books, as well as the coauthor (with Dave Tuller) of Mensa Challenge Your Brain Math & Logic Puzzles and Mensa Exercise Your Mind Math & Logic Puzzles (both Sterling). He lives in Oswego, IL.
