Mayweather-Pacquiao fight helps boost Nevada casino winnings above $1 billion in May

Huge crowds and high rollers in Las Vegas for the Floyd Mayweather-Manny Pacquiao fight helped Nevada casinos make more than $1 billion off gamblers in May.

It was the first time casinos have hit that total in more than a year.

Nevada Gaming Control Board statistics released Friday show a 3.3 percent year-over-year increase in May. The bump came despite the loss of a Strip casino at the beginning of the month, when the Riviera Hotel and Casino shut down.

Gamblers wagered $12.5 billion on table games, slots and sports bets in May.

The fight also helped boost a category of sports gambling known as "other" to a record total of $81.2 million. That category excludes baseball, basketball, football and horse racing.
