Step by step example of solving a sudoku puzzle
Step 42   Let’s look at the bottom middle box (where GHI cross MNO). We can’t put the number 8 in column O because there’s an 8 in cell EO. We already know that according to sudoku’s rules a number must show only once in a column. Therefore following simple sudoku logic, the number 8 must be in cell GM.
