What Is Sudoku?
Sudoku is a logic-based number puzzle played on a 9×9 grid. The grid is divided into nine smaller 3×3 boxes. Some numbers are already filled in, and your task is to complete the remaining empty cells.
The objective is simple: every row, column, and 3×3 box must contain the numbers 1 through 9 exactly once. Sudoku does not require any math skills—only logic, observation, and patience.
How to Play Sudoku
Sudoku follows a few simple rules that apply to every puzzle:
- Each row must contain the numbers 1 to 9 without repetition
- Each column must contain the numbers 1 to 9 without repetition
- Each 3×3 box must contain the numbers 1 to 9 without repetition
- Pre-filled numbers cannot be changed
Start by filling in obvious numbers and slowly eliminate possibilities. A properly designed Sudoku puzzle can always be solved using logic alone—no guessing required.
