Okay I'm officially addicted to Sudoku! It started innocently by occupying my time doing the ones in United's in-flight magazine last month. I didn't fully read the instructions (imagine that?) and just thought the numbers went from 1-9 in the horizonal and vertical rows w/o repeating which they do. I didn't realize the just that the numbers don't repeat in the bold boxes either. (No wonder I couldn't figure it out.) Once I did, I was hooked.
Now my brain has to do several hard puzzles a day. I found websudoku where you can do them free or print them off. It craves the deductive reasoning. I guess now with my two fantasy football teams officially out of it, there could be worse ways to waste my time... like blogging.
