Advanced Strategies to Master Sudoku
Discover professional techniques to solve any Sudoku grid, even the most difficult ones.
Sudoku is much more than a simple pastime. It's an art that requires strategy, patience, and technique. In this comprehensive guide, we'll explore the advanced methods used by experts to solve even the most complex grids.
Simple Exclusion Technique
The first technique to master is simple exclusion. It consists of examining each empty cell and determining which numbers are impossible by analyzing the corresponding row, column, and 3x3 square.
Exemple : For example, if a row already contains the numbers 1, 3, 5, 7, 9, then any empty cell in this row can only contain 2, 4, 6, or 8.
Hidden Candidates Method
This advanced technique consists of identifying numbers that can only go in one cell of a row, column, or square, even if that cell has multiple possibilities.
💡 Astuce : Tip: Focus on the missing numbers in each region rather than on the empty cells.
Naked Pairs Technique
When two cells in the same region can only contain the same two numbers, these numbers can be eliminated from all other cells in that region.
⚠️ Attention : Warning: This technique requires careful analysis to avoid errors.
Conclusion
Mastering these techniques will transform your approach to Sudoku. Start with simple techniques and gradually progress to more complex ones.
