Making Mistakes

We all make mistakes and Daisy Sudoku has three ways of dealing with them :-

• Use the backspace key to delete the last cell value if you trped the wrong character.
• Use the Go Back One button to remove the last value entered.
• Double-click the entry in the History window to go back to that point.

It is also a good idea to save the puzzle after you have entered the fixed cells.
