LAS VEGAS -- 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.

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.
