This software helps solve the mystery of the letter X.

The game is easy to play, with a number pad on the left of the grid where you can click to fill in a blank. If you accidentally enter a wrong number, you can easily erase it using the cross button at the bottom of the number pad. To help you out, there is also a Hint button that reveals a possible answer, though using it increases the amount of time you have spent by 100 seconds, as shown in the bottom left corner of the screen.
The challenge is to complete the X pattern and gain the most prestige in the Sudoku club. With well-designed gameplay and an easy-to-use interface, Sudoku X is sure to provide hours of fun and entertainment. So what are you waiting for? Welcome the mysterious member of the club and start solving those puzzles!
