Step by step example of solving a level 5 (very hard) sudoku puzzle
| Step 12 |

This is another very hard solution. It takes a lot of brain power and sudoku logic. Again we resort to the process of elimination. Let’s look at cell IJ. We can eliminate numbers 1, 5, 4, 3, and 8 because there are already showing in column J. We can eliminate numbers 3, 6, 9 and 2 because they are already showing in row I. Therefore, the only number remaining is 7. This is a classic “finding by eliminating” sudoku move. |
