This is a freeware programmed through Windows XP and earlier. It had many levels of difficulty, filled in the pencil marks, used colors, X-wing and XY-wing. I really enjoyed it. Does anyone out there know if something similar is available for Vista and Windows 7?
Or can you just point me to a site where I can get puzzles that autofill the pencil marks? I get frustrated that I spend more time adding and deleting pencil marks manually than I do solving the puzzle.
I've just joined this forum and can see that while I've away from Sudoku some really cool improvements, add-ons and puzzle designs are available. If there are any freeware games that would be good, but I'm also into supporting the developer.
Oh, also, I prefer to play on my computer rather than online, if possible.
Thanks to all the wizards out there who might have the right tonic for my Suduko withdrawal symptoms.
