What Is Sudoku?
Sudoku is a classic number logic puzzle played on a 9×9 grid. The goal is simple: fill the grid using numbers from 1 to 9 so that each row, column, and each 3×3 square box contains all digits exactly once. While easy to learn, the puzzle can become deeply engaging as difficulty increases.
