What Is Sudoku?
Sudoku is a classic logic puzzle played on a 9×9 grid divided into nine smaller 3×3 sections. The goal is simple: fill every row, column, and box with the numbers 1 to 9 without repeating any number.
Unlike math games, Sudoku does not require calculations. Success comes from observation, patience, and logical thinking.
