Black Belt Sudoku®

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.

At home, while commuting, during lunch hours…people around the world are eagerly working on Sudoku puzzles whenever and wherever they can!

Created in the United States, these intriguing conundrums were originally called Number Place puzzles. Their recent rise in popularity began in Japan, where the name translated as sudoku. Here we’ve indicated the skill level necessary to complete each sudoku book in this series in the same way Japanese karate levels are ranked: by different colored belts. This is the Black Belt volume, filled with puzzles that will provide a sly, absorbing test for even the best, most proficient experts.

It’s impossible to complete only one sudoku at a time, because solving them is habit-forming!
