Sudoku

Ok. This is getting out of hand. Over the weekend and last night I started playing Sudoku on a site that Dad sent me. Web Sudoku is too addictive. I've got the easy puzzles down, around six minutes (rank: top 37%). I'm getting better at medium, getting around ten minutes (rank: top 50%). I haven't tried hard or evil yet, but that's just, evil. Talk about an efficient time waster.
