Step by step example of solving a sudoku puzzle
Step 27   Let’s look at the right middle box (where DEF cross PQR). We can’t put a 5 in row R because there’s a 5 in cell HR. We can’t put a 5 in cell FQ because there’s a 5 in cell FM. Therefore, the rules of sudoku dictate the inevitable: the number 5 must be in cell DP and can’t be in any other cell in this sudoku box.
