One bettor won more than a half-million dollars by hitting an insane parlay during Championship Sunday in the NFL. The lucky winner turned their $20 site credit on FanDuel into $579,000 by correctly guessing the winners and exact score of both conference championship games. There's 55 555. There's just 55 555.

On Monday afternoon, one bettor at BetMGM risked $480,000, betting that the game between the Cowboys and Buccaneers goes under a combined 46.5 points. The bettor got -120 odds on the bet, paying extra juice to secure an extra point on the total. If the bet wins, the bettor will profit $400,000.
