The game field is divided into nine rows, nine columns, and nine blocks. Each row, column, and block comprises nine cells where you need to place numbers from 1 to 9. Importantly, within any row, column, or block, no number can be repeated.
Your task is to figure out which numbers are missing and accurately fill in all the blank cells of the grid.
The game offers four difficulty levels: easy, normal, difficult, and expert. You can use hints and are allowed three mistakes.
Sudoku's complexity varies depending on how many cells are pre-filled and the strategies required to solve it. Playing Expert Sudoku will sharpen your logical thinking skills and help you become a true Sudoku expert.
How to play
To complete the Expert Sudoku game, you must enter digits from 1 to 9 into every blank space, with each digit used only once per cell. Keep in mind these guidelines:
* Each digit can appear just once within the same square.
* Make sure no digit is duplicated in any column.
* Ensure that digits do not repeat in any row.
Consequently, each digit should occur only once in each row, column, and block.
