Killer Sudoku 3.9.0 Time events, challenges, and mathematical challenges

Killer Sudoku is a game for smartphones that offers many virtual sudokus to have a fun time while keeping your brains active. Playing is as simple as selecting one of the boxes and clicking the number buttons from one to nine at the bottom of the interface.

The rules are the usual in Sudokus: no number can be repeated in the 3x3 squares or in the lines. If you get stuck, you can use hints. And you also have a button to undo unlimited moves.

What sets this title apart from other similar ones is how fluid it is, its four difficulty levels (easy, normal, challenging, and expert), and its three themes (white, sepia, and black), with which you can customize the experience. It has personal statistics tracking, daily challenges, and seasonal events where you can win unique medals.
