Third-Degree White Belt SudokuŽ
For beginners who want a gentle mental workout! With a separate sudoku book for every level, all puzzle lovers can play this wildly popular, incredibly addictive game! From prolific and popular puzzle and sudoku author Frank Longo, it takes a page from karate - another Japanese art as each title 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. And because each book has an amazing 300 puzzles, the fun can go on for hours
