Simple Sudoku Solver

The Simple Sudoku solver app helps users solve Sudoku Puzzles.

This app shows an empty Sudoku grid at the beginning which the user can fill with clues as given in the Sudoku Puzzle the user is trying to solve.

With clues being entered in Sudoku grid (or Sudoku board) available solutions in empty cells of Sudoku grid will be revealed. Unsolved (or Empty) cells in the Sudoku Grid show the possible options that are possible in any cell of the Sudoku Grid.

As soon as all the clues are entered into the Sudoku grid, the complete solution is revealed. In case the complete solution is not revealed, the user can click on the button 'Random Fill' to get the final answer.

Unlike other Sudoku Solver apps which rely on hit and trial methods, this app uses some of the most commonly used Sudoku Techniques (app solves the Sudoku Puzzle like a human Sudoku Expert).

The user can select/ deselect Sudoku Techniques (Sudoku Algorithms) use in the menu of the Sudoku Solver App.

This Sudoku Solver app also continuously computes the number of solutions possible for any incomplete Sudoku grid. More than one unique solution indicates an incomplete grid (An Unsolvable Sudoku Puzzle).

The app also does a continuous error check on the entered clues which disallows any entry which will lead to an incorrect Sudoku grid (or an unsolvable Sudoku Board).

The Sudoku Solver app can also be used to create new Sudoku Puzzles. Simply enter numbers in any Sudoku Cell on the Sudoku grid and the solution will come to life.

Other functions->
1. Select Algorithms: There is a set of Sudoku Solver techniques (Sudoku Algorithms) which can be selected by clicking on the menu on the top right of the screen.

The user may play around by selecting different techniques and observe different effects on solved cells.

Very Important: Please note that some solver techniques are dependent on other techniques to be really effective and automatically include those techniques when selected irrespective of user's choice.

2. Random Fill Button: For some super hard sudoku puzzles, the app may not be able to provide a complete solution even after entering the whole grid. This is because there are a limited number of algorithms this app can apply. In such a case, the user may click on 'Random Fill' Button to generate the fully complete grid.

3. Using the app as a Sudoku Creator: Filling in numbers in an empty Sudoku Grid helps users create new Sudoku Puzzles.
