KrazyDad is krazy awesome!
Bazillions of killer sudoku puzzles! I first discovered these sometime in the spring when I found a book of them at Issues. I ripped through that book (despite a frustrating predilection for using 9 and 8 to make 16) and haven't seen another on the news-stand since. But now KrazyDad has come to my rescue and I'm addicted all over again. (Ok, so maybe that's not the generally accepted use of rescue and addiction, but tough.)
