When I get a pop up on a puzzle that I am copying from the daily newspaper stating that the puzzle is Asymmetrical what does that mean? The puzzle is presented incorrectly or it has more than ONE solution?

Thanks.

You have not specified which program you are using. There are several Sudoku programs.

But in general:

Most puzzles in newspapers are symmetrical, which means that the pattern of the given numbers has reflectional or rotational symmetry (or both).

When a program warns you that the puzzle you enter is asymmetrical, it does not have to be invalid, but the warning tells you that IF you were entering a symmetrical puzzle, you must have made a mistake.

Thanks for your time.

I didn't think it would make a difference which program I was using. It was one called Simple Sudoku by Angus Johnson. It came with a set of puzzles to work but I choose to enter the numbers from our daily newspaper. After entering the numbers, if I click "start" I see a message on the Status Bar that the puzzle is asymmetrical. This isn't on all puzzles so I wondered what this meant.

I rather assumed it meant there was more than one solution.
