| Are you referring to a particular puzzle or to Sudoku in general? |

1. Find a digit lying in two horizontal/vertical blocks. Where should the digit lie in the third block? Check all three block-rows and block-columns.
2. Check each row and then each column for the missing entries.
3. Check each block for its missing digits.
4. Check each empty cell for a unique solution.
5. Repeat 1-4.
6. If there are still some empty cells, draw pencilmarks for them and analyze.
7. If the puzzle still resists, advanced techniques like X-Wings and Swordfish are to be employed.
Good luck! |
