Sudoku, but really really easy.

I love Sudoku puzzles. Okay, I love puzzles in general, but Sudoku is one of those puzzle types that particularly appeals to me. The various strategies that can be used to tackle the hardest puzzles really requires to you keep thinking, and looking for patterns. Of course, it takes a while to learn those strategies, so most people who publish Sudoku puzzles publish them with gradings of difficulty.

I think this one was graded, "Not actually a puzzle".
