This vid is awesome! It was over an hour long at first so I had to CUT CUT CUT!! I left only the important things about doing a Sudoku. This video is not about how fast I can finish a puzzle. It's simply to show easy tricks and strategies to do a very difficult puzzle. Best to watch in high quality (HD)

Update on 1-25-11: Hi, it's Tiff. I just wanted to thank everyone for so many positive comments. I'm so happy to learn that so many of you all are better off after watching me than before. It really justifies why I did a video. I want to do another video but my flip broke, so I'm not sure a new vid will happen too soon. But I totally welcome you to send me a puzzle that you are stuck on. I will gladly give the next hint or even solve the whole puzzle for you.
