Strategies to Solve Sudoku Like a Pro

Move from beginner to expert with these key strategies for Sudoku:

  1. Start with "Scanning": Look for rows, columns, or 3x3 boxes that are almost full. Find the obvious missing numbers first.

  4. Practice "Cross-Hatching": Visually scan rows and columns to see where a specific number can and cannot fit.
