The Original Sudoku [Paperback]

Over twenty-five years ago, Nikoli, a Japanese puzzle and game company, started publishing a curious logic puzzle called Sudoku. The result was magical and in recent years, Sudoku has spread from Japan to other countries. These newer puzzles, however, are often computer-generated and lack the simple beauty of handmade puzzles. Nikoli continues to nurture and develop Sudoku with handmade puzzles that contain the vital ingredient that make puzzles enjoyablethe sense of communication between solver and author. The best Sudoku make you concentrate, but arent stressful.

Arranged from Easy to Very Hard, here are over 300 logic puzzles that celebrate the compulsive joy of Sudoku with symmetry, smartness, and elegance. Absorbing and engaging, every puzzle is designed by an author who anticipates your next step and obscures the path, while never leading you into frustration. Each puzzle carries the careful thought of a master who knows when to encourage and when to withhold, who shares the joy of that moment when one hard-won number is captured and the entire puzzle falls into place.
