For advanced solvers. Minimal clues, maximum logic — bring your full toolkit.
★ Solved
Brilliant!
Expert Sudoku strips the grid down to 23 to 26 clues. Every placement has to be earned, and a single careless mark can cost you the whole solve.
What an expert puzzle demands
This is where advanced techniques earn their keep. Every expert grid on Sudoku.tips needs at least one of the X-Wing, its bigger cousin the Swordfish, or the XY-Wing (occasionally a naked quad) — on top of everything from the hard tier. You will hold many candidates in mind at once and eliminate them pattern by pattern.
Who expert Sudoku is for
Solvers who have mastered the intermediate techniques and want a genuine test of skill and patience. If you want it even harder, try evil.
Frequently asked questions
Is expert Sudoku solvable without guessing?
Yes. Every expert grid still has one logical solution — it just needs advanced techniques like the X-Wing, Swordfish or XY-Wing.
