A new expert Sudoku puzzle every day. With only 22-28 clues, the ultimate daily challenge requiring advanced strategies.
Expert daily puzzles require mastery of advanced strategies including XY-Wing, coloring, forcing chains, unique rectangles, and Jellyfish. Basic and intermediate techniques will get you partway through, but you will inevitably reach points where only expert-level logic can break through.
With only 22-28 clues provided, the grid starts quite sparse. Meticulous pencil marking and systematic candidate elimination are non-negotiable. Every elimination matters, and a single mistake in your candidate tracking can derail the entire solve.
Work through all simpler techniques first: singles, pairs, triples, pointing, box/line reduction, X-Wing, and Swordfish. When these stall, look for XY-Wing patterns: three cells forming a chain where each cell has exactly two candidates. The pivot cell shares one candidate with each wing cell, and the candidate shared by both wings can be eliminated from cells that see both wings.
Forcing chains involve assuming a value for a cell and tracing the logical consequences. If both possible values for a cell lead to the same conclusion elsewhere, that conclusion must be true. Unique rectangles exploit the fact that a valid Sudoku has exactly one solution. Read our expert solving guide for comprehensive walkthroughs.
Committing to a daily expert puzzle is the fastest way to sharpen your advanced solving skills. Even if you cannot finish every puzzle, the practice of searching for complex patterns builds the mental habits that make expert solving feel natural over time.
If expert puzzles are still frustrating, consider alternating between daily hard and daily expert puzzles. This approach builds your skills progressively while still pushing your limits. Read more about building a Sudoku daily routine and how to get faster at Sudoku.
Each daily expert Sudoku puzzle contains between 22 and 28 given clues. This sparse starting grid means you will need to build extensive pencil mark networks and use advanced elimination strategies to work toward the solution.
Expert puzzles demand mastery of advanced strategies including XY-Wing, forcing chains, coloring, unique rectangles, and Jellyfish. You must be fluent in all basic and intermediate techniques as well, since expert solving builds on a foundation of simpler methods applied first.
Most experienced solvers spend 30 to 60 minutes or more on an expert Sudoku puzzle. The sparse grid and need for advanced techniques mean longer solving sessions with more complex chains of deduction. Regular daily practice shortens these times significantly.
Hard puzzles typically require X-Wing, Swordfish, and coloring, while expert puzzles add XY-Wing, forcing chains, unique rectangles, and Jellyfish. Expert puzzles also have fewer starting clues (22-28 vs 25-29), creating even sparser grids that demand more sophisticated elimination chains.
