Again Sudoku Scan/Solve Extra

Different levels/skills with 3x3 (standard) and 2x2 small layouts.

This version contains ads. An ad will be shown each time after a solved game.
Internet access/connection will be used and may be mandatory for some functions.
The ads are transferred through the standard API.

You may solve Sudoku automatically with a double tap on the 'play' button.
Further this version allows scanning printed Sudoku ('scan' button).
Camera itself and 'camera access' permission are mandatory (obvious technical reasons) to enter the scan function.
Only back side camera may be used for scan. An appropriate resolution is required.
Optionally 'storage write' permission is required to save a scanned picture (user defined option, initially set off).
Hint: Stored pictures (i.e. scans) may be accessed from other applications if the store option is enabled.
