6×6 Sudoku Solver FAQ
Can the solver detect an invalid board?
Yes. It checks rows, columns and 2×3 boxes for repeated numbers, then tests whether the remaining grid has a solution.
Can I ask for one move instead of the full answer?
Yes. Select an empty cell and choose Next step. If the selected cell is filled, the tool finds the next empty cell.
Does the puzzle leave my browser?
No. Validation and solving run locally in the page.
