When you enter a game (from newspaper, for example), and click on File > save as .. the game crashes
I think sudoku is sudoku. End of story. This game adds themes and some good ideas to make that classical even more funny. If capability to get more themes (or customize them), and turn off guessing would be added, that will make KSudoku better. Nevertheless, the game is just addictive. Great job.
One MAJOR problem! Sudoku is a logic game - guessing is no part of it!!! Guessing should not be built in, it destroys the game. Please remove guessing, or if you feel you can't do that; at least give an option to turn it off.
Good sudoku game
