Nevada’s 191 sports books took in almost $116m (€101m) in bets on Sunday night's Super Bowl between the Seattle Seahawks and the New England Patriots.
The overall profit for bookmakers in the state was $3.2m (€3.7m), down from $19.7m (€23m) last year - that's a 84 percent decrease.
Late drama saw the Patriots intercept Russell Wilson's pass from the one yard line - effectively killing the game.
This play caused heartache in both Seattle - and in Nevada where millions of dollars of potential revenues for the state's bookmakers were wiped out.
Vice president of Race & Sports for MGM Resorts International, Jay Rood told Bloomberg that the throw, and Seattle's failure to steal the game, caused a "significant seven-figure swing" in revenue for MGM.
He continues: "It was real tough, when it looks like you’ve got it locked up and then you have it snatched away from you because of a really weird decision."
Nick Bogdanovich, director of trading for William Hill U.S said that the company "got killed on the game itself" but managed to return a slight profit on revenues from other betting options.
There was also a popular over/under market that saw a lot of punters betting on more than 47.5 points being scored - the game ended with 52 points on the board.
Bizarrely a simulation run by EA's Madden 15 video game predicted the New England win - and the exact 28-24 scoreline.
It even correctly predicted that the game would be won by a touchdown pass from Tom Brady to Julian Edelman - and that Brady would be the MVP.
