If you entered any online bracket contests for the NCAA tournament you won't be coming back with a perfect one.

One man from Illinois, Brad Binder picked the first 36 games correctly. Binder was wrong though when it came to Syracuse vs. Dayton.

Binder did share a small secret to his semi success. He said that he was in a total rush when he filled out his bracket as he was running late. So, he logged on made his picks and kinda forgot about it.

In all the years that websites have been running online contests for brackets NOBODY has even come close to getting there.

However, your chances are 9.2 quintillion-to-1 so, there's that.
