Sudoku Solver - Enter the Digits and Press Solve!

Quickly complete any sudoku puzzle

When it is completed it will probably present you with a completely filled Sudoku. It might, however tell you it can't solve it purely by logic.

This typically means the start state you gave it didn't provide sufficient information, and there were multiple options probable - the solver would have to guess a number instead of being able to obtain it from logic.

Then, you will be asked if you want to use a search algorithm to still get hold of an answer.
