Can I clear the puzzle sheet and enter a new puzzle from the newspaper?
No, the game doesn't allow you to enter custom sudokus from the newspaper. I have installed the game and there was no possibility add custom sudokus. You will need another game that supports custom content or at least using a free editor to enter custom sudokus. The Kitty Spangles Sudoku game allows you to do that. Access the official website to download a copy of the application.
