How to Play Sudoku: Step-by-Step Instructions
Solving your first Sudoku puzzle might seem intimidating, but breaking it into steps makes it manageable.
Step 1: Understand the Grid
Familiarize yourself with the structure. Remember:
- Each row, column, and 3×3 sub-grid must include all digits from 1 to 9.
- Numbers cannot repeat within any row, column, or sub-grid.
Step 2: Start with the Easy Clues
Look for rows, columns, or grids that already have several numbers filled in. Use these as starting points.
Step 3: Scan for Opportunities
Use the process of elimination:
- If a number is already in a row, column, or grid, it can’t be placed there again.
- Focus on “naked singles”—cells where only one possible number fits.
Step 4: Pencil In Possible Numbers
For tougher puzzles, write down potential numbers in empty cells. This will help visualize your options.
Step 5: Apply Advanced Strategies
For more challenging puzzles, use techniques like:
- Naked Pairs/Triples: Groups of numbers that can only occupy certain cells.
- X-Wing or Swordfish: Techniques for spotting patterns across rows and columns.
Step 6: Check Your Work
Once the grid is complete, double-check to ensure every row, column, and grid adheres to the rules.
