Sudoku
Fill the grid so every row, column, and 3×3 box has the numbers 1–9.
Tutorial: Sudoku
How to Play:
- Fill every cell with a number from 1–9.
- Each row, column, and 3×3 box must contain every number exactly once.
- Tap an empty cell to select it, then pick a number from the keypad.
- If a number already appears in that row, column, or box, it can't go there.
- Use elimination — when a cell can only be one number, that's your answer.
Pro Tips:
- Start with rows or boxes that already have the most numbers filled in.
- Look for a number that can only fit in one spot within a row, column, or box.
- Check the same number across multiple boxes — they often rule each other out.
