The Nevada Gaming Control Board said Tuesday that $87.5 million were wagered on the NFL's championship game in 183 sports books across the state.
Of those bets, casinos kept less than 1 percent.
Green Bay beat the Pittsburgh Steelers 31-25 in Cowboys Stadium in Arlington, Texas, on Sunday night. The Packers were a 2 1/2-point favorite in most Las Vegas casinos, giving their supporters a win with the six-point victory.
The combined 56 points scored helped bettors who gambled that the total would go over about 45 points.
Nevada casinos won $6.9 million on $82.7 million in Super Bowl bets last year.
