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 the skill level necessary to complete each sudoku book in this series is indicated in the same way as Japanese karate levels: by ranked colored belts. This is the White Belt volume, a great introduction for anyone who wants to find the perfect beginner’s challenge.

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