(NEW YORK) -- After a number of NCAA Tournament upsets on Thursday and Friday, Warren Buffett can rest easy; there are no perfect brackets remaining in the billion-dollar challenge. Through 32 games, favorites like Duke University and Ohio State University have seen themselves eliminated, and so have millions of Americans' brackets. More than 11 million people are participating in ESPN's tournament challenge, and none of them are still flawless.
Quicken Loans, the sponsor for Buffett's billion dollar offer, said that 99 percent of all brackets were eliminated by either Ohio State University's loss to the University of Dayton or Duke University's loss to Mercer University.
Still, that doesn't mean that no one's bracket is perfect. Yahoo reports that one contestant correctly picked the tournament's first 32 games, but did not sign up for the billion-dollar contest.
Quicken Loans is still giving out $100,000 each to the 20 best "imperfect" brackets.
