Features: Dr. Cho explains how to use "Four-Character Codes" (four digits and symbols) to describe each step of Sudoku puzzle-solving in terms of position, logic, and the number to be filled. This transforms traditional Sudoku into a more methodical, ordered, and evidence-based game, highlighting logic and decision-making. Additionally, it allows for creating puzzles tailored to the objective difficulty of the solving methods, providing readers with advanced brain-training exercises. With this content-rich enhancement, Sudoku gains a new face, making it enjoyable and logical to play. Dr. Cho has given it a Chinese name—Sudoku Kool!!
