Wynn Las Vegas has become the first casino to take advantage of new rules adopted earlier this year by the Nevada Gaming Control Board allowing for non-sports prop bets, offering wagers on the World Series of Poker main event.

Wynn Race and Sports Director Johnny Avello told the Associated Press that regulators approved the wagers earlier this July after more than one month of work, to satisfy that the event is legitimate enough to prevent players from having a significant edge on bets."This just opens the door to do a lot of things." For the series' main event, the Wynn has begun accepting bets like whether a woman will finish higher than 40th in the male dominated tournament, and whether poker legends Johnny Chan, Allen Cunningham or Erik Seidel will win money in the event.

Avello said the bets were popular and that he'd accept up to $10,000 wagers - enough to make money but not enough to make it reasonable for a player to throw the tournament given its pricey entry fee.

The growth of non-sports betting could pick up in earnest with the entry of UK-based book operator William Hill into the Nevada market, which expects to receive its license by November, according to published reports. The company earlier this year purchased Nevada-based sports-betting companies Brandywine Bookmaking LLC, American Wagering Inc. and Club Cal Neva. The company is known to be interested in offering wide range of non-sports prop bets, which are very popular in the UK, to bettors in Nevada.
