Solving Strategies for Tough Grids
Tackling a hard Sudoku puzzle requires more than just basic scanning. Advanced techniques are key. You'll need to look for how numbers interact across rows, columns, and blocks in complex ways. Often, candidates that appear impossible at first glance become clear with a systematic approach. Don't be afraid to use pencil marks (or 'candi-marks' as some call them) to track potential numbers in empty cells. This allows you to see patterns and eliminations more effectively. Patience and persistence are your greatest allies when facing these particularly tricky grids.
