What is Sudoku?

Sudoku is the timeless daily number puzzle: fill the 9×9 grid so every row, column, and 3×3 box contains the digits 1–9 exactly once.

How to play Sudoku

Use the given numbers to deduce where each digit must go. Every row, column, and box needs all nine digits with no repeats — logic alone, never guessing, solves a proper puzzle.

Tips & strategy

• Scan for digits that can only fit one cell in a row, column, or box.
• Pencil in candidates for tricky cells and eliminate as you go.
• Naked and hidden pairs unlock most medium and hard grids.
