Today's Free App of the Day is Sudoku 10'000 Plus
This is a full featured Sudoku game with great reviews so far (and they don't seem to be by the developer, for the most part). It's got all the little bells & whistles one wants from a Sudoku game, and also lets you build your own. Very cool.... I haven't tried it yet--if anyone does, let me know if it lives up to its promise. I'm downloading it, for sure.
7 of 7 reviews are four stars and above.
