USA TODAY -- It's not impossible to fill out a perfect NCAA tournament bracket, but it's as close to impossible as you can get.
There are 9,223,372,036,854,775,808 ways to fill out a bracket (that's 9 quintillion), and though basketball experts have slightly better odds (around 1-in-128 billion), the parity in college basketball this year will make the 2014 bracket one of the hardest in recent memory to fill out come March.

That's probably why Quicken Loans is offering a $1 billion prize to anyone who fills out a 100% perfect bracket. If someone beats the odds, Warren Buffett will foot the bill, with Quicken Loans CEO Dan Gilbert, owner of the Cleveland Cavaliers, paying Buffett's Berkshire Hathaway a hefty premium to insure the prize.

According to CNN, Buffett will attend the title game if there's a chance some fan could win. Via CNN Money:"I will invite him or her to be my guest at the final game and be there with a check in my pocket, but I will not be cheering for him or her to win. I may even give them a little investment advice."
A grand-prize winner can choose to receive $25 million per year for 40 years, or a lump-sum payment of $500 million. Quicken is also offering $100,000 prizes to each of top 20 brackets submitted, so at least some money will change hands.
Entry is free. Contestants can sign up March 3, but won't be able to make picks until brackets are set March 16. The deadline is March 19. Will you participate?
