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.

A 'Trixie' bet consists of four bets from three selections, and includes three doubles and one treble.

Players bet on the number they predict will win before the host sets the wheel in motion. The winning segment is indicated by a pointer when the wheel halts. The payout system is simple and directly corresponds to the numbers on the wheel, with a bet on a number paying out at that number to one.

A correct answer awards the money at stake to the contestant and ends the game. If the contestant misses, they are returned to the smaller wheel and a new contestant is chosen. The subject of the missed question, the expert chosen for it, and the prize associated with them are all removed from play.
