How to solve Sudoku

Sudoku is a 9×9 square grid split into nine small 3×3 boxes. Place the digits 1–9 so that three rules hold.

  • Every row contains each of the digits 1–9 exactly once.
  • Every column — once each too.
  • And every small 3×3 box — once each.

How to place a digit correctly

5 is the only possible digit: the other eight already sit in its row, column or box.
Wrong
Not allowed: 8 is already in this row.
Wrong
Not allowed: 8 is already in this column.
Wrong
Not allowed: 8 is already in this small box.
