The mysterious gambler who won $10 million on last year’s Super Bowl has placed a $1.5 million bet on the Los Angeles Rams for Super Bowl LIII.

The unidentified bettor took money-line odds of +120 on the Rams to beat the New England Patriots in the championship game today in Atlanta, paying out $1.8 million if the Rams win.

The bet was placed through the William Hill mobile app, which confirmed to the newspaper that the gambler was the same individual who placed $7.4 million on various money-line bets on the Philadelphia Eagles in Super Bowl LII.

In that game, the underdog Eagles beat the Patriots 41-33.

According to the Las Review-Journal, the mystery bettor also cleaned out bookies for millions of dollars in the 2017 World Series.

The mystery gambler’s bet on Super Bowl LIII was large enough to move the line on the William Hill app, which lowered the Patriots from 3-point favorites (even) to 2.5-point favorites (-110).

As of Saturday night, the Las Vegas consensus has the Patriots as slight favorites at 2.5 points (-110).

The over/under for the game stands at 56.5 at most Las Vegas books.

Across the country, an estimated $6 billion is expected to be wagered on the Super Bowl this year.

According to a new survey released by the American Gaming Association, which lobbies on behalf of the casino industry, 22.7 million Americans plan to place a wager on Super Bowl LIII.

The United States Supreme Court stuck down the Professional and Amateur Sports Protection Act (PASPA) last year, effectively giving states the right to legalize sports gambling. Since then, eight states have legalized the practice.

But despite the increasing accessibility of sports gambling, the AGA study found that 1.8 million Americans plan to bet illegally through a bookie, and that does not include the millions that will be bet through offshore, online sports books.
