About Sudoku

Sudoku is a classic number logic puzzle game, typically played on a 9x9 grid divided into nine 3x3 sub-grids. At the start of the game, some cells are already filled with numbers. Players must use logical reasoning to fill in the empty spaces with numbers from 1 to 9, ensuring that no two numbers are repeated in any row, column, or 3x3 sub-grid. Sudoku requires no mathematical calculations; it relies solely on logical reasoning, making it a classic puzzle game for developing thinking skills and concentration.
