Expert-Level Solving Strategies
Here's how to approach expert sudoku puzzles:
Master Chain Logic Expert puzzles often require building chains of linked candidates. When one candidate must be true, it forces a sequence of other candidates to be true or false. Learning to spot and use these chains is essential for expert-level solving.
Work with Forcing Chains Sometimes you need to test what happens if you place a number in a particular cell. Follow the logical consequences. If it leads to a contradiction, you've found that the alternative must be correct. This trial-and-error approach is more systematic than it sounds.
Understand Almost Locked Sets ALS (Almost Locked Sets) is an advanced technique that identifies relationships between groups of cells. When you spot these relationships, you can eliminate candidates across multiple cells at once. It's complex but incredibly powerful once you get the hang of it.
