Sudoku

So, while my parents were in town, I was introduced to sudoku . . . but I didn't really listen when it was explained to me. When I did them at first, I realized that each number could only appear in a row or column once, but didn't realize that they could also only appear in each 3x3 box once. Amazing how much easier they are once you realize that . . .
