🧩 4x4 Sudoku

📖 How to play 4x4 Sudoku

1. Fill the 4x4 grid with numbers from 1 to 4.
2. You can't repeat a number in the same row.
3. You can't repeat a number in the same column.
4. You can't repeat a number within each 2x2 box.
5. Tap an empty square and then the number you want to place. Easy!

💡 Tip for kids: look for the row, column, or box where 3 numbers are already placed; the missing one can only go in one spot.

✏️ Notes mode: press the ✏️ button on the keypad (or the N key) to jot down candidates in the empty cells.
