Sudoku : Game Over

What a bad day! I just passed the 1st round out of 3 rounds. But it is okay, at least, I've learned something from that. Don't forget to congratulate me on being in the top 30 from a total of 96 participants. The first round was very easy. I just took a glance and filled in. The second round was quite difficult, not as easy as the first round. There were only me and Vannessa who represented XII-A-6 and both of us didn't pass, haha.
