Sports books in Nevada won just over $724,000 from Super Bowl bets despite heavy gambling on the Green Bay Packers and lots of scoring, Nevada gambling regulators said Tuesday.

The Nevada Gaming Control Board said $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 at 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.

Mike Lawton, a research analyst with the control board, said that while some casinos won, others had moderate losses.

"There wasn't anyone that lost anything mind-blowing," he said. "I think we were really worried about it being a loss — it could have been worse."

Gamblers wagered 5.5 percent more this year than last year, when Nevada casinos won $6.9 million on $82.7 million in Super Bowl bets as New Orleans beat Indianapolis, 31-17.

Casinos have lost once only once on the Super Bowl in the last 10 years, in 2008 when bettors gambled $92 million and casinos lost $2.57 million as the New York Giants beat New England, 17-14.

This year was the slimmest winning Super Bowl for casinos since 1998, when books won $472,000 on $77.2 million in wagers. The Denver Broncos beat Green Bay in that game, 31-24.
