Obsessed with Sudoku

I'm obsessed with Sudoku. For those who don't know what that is, it's a puzzle with a 9X9 box. Each 3X3 box, each row, and each column have to contain all the numbers 1 to 9.

For those of you in UBC, grab a copy of National Post and try it! You'll get addicted too. I've been grabbing National Post just for Sudoku. I just solved a "Diabolical" level one (the hardest level in National Post). So proud of myself. Haha.
