This application uses the constraint method to solve the puzzle, which is similar to how a human mind works when solving Sudoku. This application has a limited set of solving methods coded in, that help towards finding leads to the existing puzzle.

The User experience has been carefully designed so that it would be convenient to input numbers into cells, try to figure it out yourself:)

When you're done with entering the puzzle, just press the smiley at the bottom to view t he solution.

Disclaimer:
1. The algorithm may not be able to find solution to some advanced puzzles.
2. This app does not guarantee the leads found by the algorithm are the only possibilities.
