Are you ready to tackle today's medium-level Sudoku puzzle from The Guardian? Puzzle 6998 offers a satisfying challenge for both beginners and seasoned solvers. Here’s how to approach it with confidence.
Understanding the Grid
Start by scanning the 9x9 grid for obvious numbers. Look for rows, columns, or 3x3 boxes with the most filled cells—these often hold the easiest clues.
Step-by-Step Solving Strategy
- Fill in the Obvious: Identify single missing numbers in any row, column, or box.
- Use Pencil Marks: Lightly jot down possible numbers in empty cells to narrow down options.
- Look for Hidden Singles: A number might only fit in one cell within a row, column, or box, even if other candidates seem possible.
- Eliminate Possibilities: Cross out numbers that can't logically fit based on existing placements.
Advanced Techniques
If you're stuck, try these pro tips:
- X-Wing: Look for two rows or columns where a number can only appear in two identical positions, allowing you to eliminate it elsewhere.
- Skyscraper: A more complex pattern that helps eliminate candidates across rows or columns.
With patience and practice, you’ll crack today’s puzzle in no time!
