I have to do a project on Sudoku. I am finished generating the complete board. Now my major task is to generate a puzzle out of the complete board with the difficulty level. Can some one give me clue to remove the elements randomly from the board. Later on once the board is partially filled i have to check such that the board has a unique solution and then design the difficulty of the board.
Can some one help me please. I have this project due this week. I am ready to work hard day and night. This project is so important for me in the course. I would appreciate if some gives me hints and help me completing this project..
Thanks in advance
