Sudoku Juixo

Sudoku with guessing...Not good.

For some reason, the menu with options to "Go to Calendar", "Close" and mute "Music" and "Sound" popped up covering a good portion of the playing area. I clicked on "Close" but the menu didn't go away. Nothing I can do closes the menu. Seems like a bug.

you dont need guessing. you need advanced techniques for elimination of possibilities...
