Sinister Sudoku is a really hard sudoku game. At the beginning, only a few numbers are already placed. When you try to place a number, some cells positions are changed. This makes the game change at each number you add on the board. You will need to watch out at each movement, to be sure that your numbers are still right. The atmosphere doesn't help to concentrate, so remain calm and determined if you want to end this game without going crazy!
