Hello. 16 January 2013 released a major update the program to version 2.2.2
The update includes:
1. According to numerous requests of our users added ability to set all of the digits of the candidates of a single button. This greatly simplifies and speeds up the process of solving a puzzle.
2. Fixed a bug clicking "Restart". Now when you select this menu item restarts the game on the same playing field.
3. Fixed the basic algorithm of the game, which increased the speed and stability of the game.
4. Minor bug fix
The project continues to develop. Looking forward to your feedback and suggestions.
