Hi everyone, My mom just replaced her Windows PC with my dad's old G5 iMac. She would like to play Sudoku on it. Can anyone recommend a good Sudoku game for OS X? Free or commercial, it doesn't matter. It should just be easy to use, and maybe should be able to give hints if she gets stuck. Oh, and not the Sudoku widget; she's not too comfortable with computers and I think Dashboard will only confuse her. Thanks!
