Absolutely Nasty Sudoku Level 3 based on 0 ratings. 1 reviews.
Well, I call it nasty fun! I get to a point I can't solve so I move a few pages ahead then work backwards. By the time I get to the can't solve spot it seems like a breeze to work. I find I'm learning and my skills are moving forward as I enjoy this series.
