What is Sudoku?

Sudoku (سودوكو) is the world's most popular number puzzle, played by millions daily. On a 9×9 grid divided into nine 3×3 boxes, you fill cells with numbers 1-9 so that each row, column, and box contains every number exactly once. No math is required — it's pure logic and deduction. Our version features 4 difficulty levels (Easy, Medium, Hard, Expert), a daily puzzle that's the same for everyone, pencil marks for noting candidates, hints when you're stuck, and a mistake counter. Arabic Sudoku sites barely exist — this fills a massive gap.

How to Play Sudoku

Sudoku is a logic puzzle on a 9×9 grid:

1. Start: The grid comes pre-filled with some numbers (givens). These cannot be changed. Your job is to fill in the empty cells.
2. Rules: Each row must contain 1-9 exactly once. Each column must contain 1-9 exactly once. Each 3×3 box must contain 1-9 exactly once.
3. Solve: Use logic to determine which numbers go where. Use pencil marks to note candidate numbers in cells when you're unsure.
4. Win: Fill all 81 cells correctly. If you make 3 mistakes, the game ends. Use hints (💡) if you're stuck — they reveal one correct cell.
