Hi ,I want to generate a sudoku game in c sharp.First I will make 3*3 cells sudoku simple,then whole sudoku (9*9) . I ve added to form 9 commoboxes and a star button.
When ı click the start button , the programme will fill randomly two cells with 1, 2, or 3 .
Then player will fill other empty cells and check its correctness by clicking check button.
