How to Play Sudoku
Fill the 9×9 grid so that each row, column, and 3×3 box contains the numbers 1–9 without repetition.
- Start with obvious singles: cells that have only one possible value.
- Use elimination: scan rows, columns, and boxes to remove impossible numbers.
- Look for pairs and triples: candidates that restrict other cells in a unit.
- Work logically—avoid guessing. If stuck, switch focus to another area.
- Increase difficulty to challenge your deduction skills.
