X Sudoku differs from the classic Sudoku fact that it must also complete two main diagonal numbers from 1 to 9.
This game differs from most Sudoku games because it does not use ready templates, and the game generates itself each time you play it. Thus, it is very unlikely to get the same combination of Sudoku ever.
Sudoku has four levels of difficulty. At all levels, the solution is guaranteed by using logical way only. It is not required to guess numbers.
The game has two modes.
In the first mode, your selection number is automatically marked by highlighting on the playing field.
In the second mode, numbers are not highlighted. The second mode is more difficult for perception and the game takes more time. Therefore, when playing in the second mode, the score is doubled compared with that in the first mode.
After you have solved the Sudoku, you are assigned a certain number of score. The faster you solve a game, the higher score you are assigned.
Local statistics on your device may be reset any time at your wish.
There are 5 preset styles of the playing field and sound effects: Default, Classic, Glass, Metal and Wood.
Enjoy the game!
