Sudoku Puzzle Game(Free)

-The Sudoku game uses a square consisting of 81 squares, 9 squares each, divided into 9 squares and 3 squares each called "zones".   The square is already filled with some numbers.   The goal of the Sudoku game is to fill in the remaining spaces so that the numbers from 1 to 9 do not overlap (only one number can be used in each space). 1. Use only one number in each blank line. 2. Use only one number in each blank space. 3. Use a number only once in the space of each small square.    In summary, these guidelines should be used only once so that the numbers do not overlap each other in the horizontal and vertical lines, and in the blanks of small squares (areas). That's it. Now you are ready to solve Sudoku puzzles.
