Sinister Sudoku isn't a sudoku game like the others ... The version risks to drive you literally crazy. The difficulty is, at the beginning, relatively high: you only dispose of a few numbers to start filling the board. The problem is that each time you enter a new number in a case, all the numbers around are changed. You will need a lot of perseverance and determination to end this game. Moreover, the atmosphere doesn't help, it stresses you just a little bit more ... Do your best to stay calm if you want to win at least once.
