App Sudoku Prof for Android for PC

Multiple Sudoku puzzles can be created, stored in a database (DB) and printed. The app provides full professional functionality for creating and publishing Sudoku puzzles.
Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid contain all of the digits from 1 to 9.
Filling in one puzzle in the application can be done: - in automatic mode; - and in sequential fill mode, and whether it is filled correctly can be controlled.
The application has the ability to store one intermediate state of the puzzle and in a delayed time restore that state and continue the filling process.
The size of the number field (rows and columns) can be selected from a drop-down list, the classic Sudoku puzzle is in 9x9 grid.
The grid can be stored as an image file named imageSudoku.png.
The file stored in the main memory of the device from there can be sent for publishing.
