Step by step example of solving a level 5 (very hard) sudoku puzzle

Step 32   Let’s look at the top left box of the sudoku puzzle (where ABC cross JKL). We can’t put an 8 in cell CK because there’s an 8 in cell CM on the same row. Sudoku rules do not allow number repetition on the same row. We can’t put the number 8 in cell BL because there an 8 in cell GL on the same column. Therefore, the only option for the number 8 is cell AK.
