This might be the highest grand prize on the internet; Sportsbook.com is offering a $13,000,000 cash prize if any contest participant can score a perfect bracket—one million dollars for every year they’ve been taking action on March Madness.

That’s not the only way to win, however, as there’s also a guaranteed $10,000 in cash prizes available. The perfect bracket is a longshot for sure, but definitely worth a try for college basketball handicappers.
