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.

Calculating Winnings\n\n Odds of 7/5 mean you'll win $7 for every $5 you wager on the A's. Conversely, the Rangers' odds of 5/8 mean you need to wager $8 to win $5 on Texas. Another way to look at it: If the first number is larger than the second, you're betting on the underdog for a higher potential payout.
