What is Sudoku?
Sudoku is the world-famous number puzzle. Fill a 9×9 grid with the numbers 1 to 9 so that no number repeats in any row, column or 3×3 box. It's relaxing and challenging at the same time — pure logic, no maths needed.
How to play
- Choose a difficulty level.
- Tap a cell to select it, then choose a number.
- Use the erase button to fix mistakes.
- The puzzle is done when every cell is filled correctly.
Tips
- Start with the busy areas. Rows, columns or boxes with many numbers already filled are the easiest.
- Look for the only spot. Ask "where can the 5 go in this box?" — often there's only one place.
- Don't guess. Every Sudoku can be solved by logic alone.
