Six Sudoku variants to explore

Understand your next move

Sudoku hints help you follow the reasoning. Focus on the relevant cells, explore the explanation, and work through the deduction step by step. Learn why a number belongs in a cell or why a candidate can be eliminated.

Choose how far to follow a hint before continuing on your own. If no supported logical hint is available, you can reveal a cell to move forward.
