Want to construct a valid Sudoku for friends and family?On this page you can do that.
When you enter a number, you will receive direct feedback as to whether it is still a valid Sudoku.
If you have
- entered a few numbers and
- possibly specified which cells should remain empty or
- which cells should contain numbers in the end,
then you can let the generator
automatically complete the Sudoku into a correct, uniquely solvable one.
