Sudoku

Fill the 9×9 grid so every row, column and box has digits 1–9.

0:00

Start with rows, columns, or boxes that already have the most numbers filled in.
Look for the only empty cell in a row/column — it must take the missing number.
Use "elimination": if a number appears in 2 of 3 rows in a box, it must be in the third.
Stuck? Use the Hint button to reveal one cell.

🎉 Solved!
