Features: The only official authorization from the Sudoku authority, Nikoli. The real Sudoku is here! Computer-designed Sudoku is a decline in thinking, while handmade Sudoku is the true brain battle! "It inspires imagination in people of all ages and has been used by schools as a teaching tool for logical thinking." — Robin Wilson, a renowned British mathematician and authority on geometry. Nikoli has uncovered the popular characteristics of the Sudoku game—originality, handmade, symmetrical patterns, and mental fun—and has hosted the compilation of a series of Sudoku puzzle books, becoming the authority in the Sudoku game field. True Sudoku is not just a mechanical change of numbers and grids. Hidden in the shifting of numbers lies unique creative thinking: each Sudoku puzzle is handmade, showcasing wonderful thinking and exquisite patterns; each Sudoku puzzle has only one unique answer, which can be cracked through pure logical reasoning. The highly personalized Sudoku game is a mental confrontation between each creator and each player! Do you want to challenge? This book is divided into three difficulty levels—easy, medium, and hard—based on the solving difficulty of Sudoku games. Next to the difficulty level of each game is a small pencil. The number of sweat droplets next to the pencil increases with the game's difficulty. Even if the number of sweat droplets is the same, the difficulty coefficient will increase accordingly due to the different levels of the game. As for the puzzles covered in sweat droplets, solving them might make you break into a sweat!
