ators William Hill US have launched a new version of their Mobile Sports app.

The updated product from the William Hill subsidiary gives Nevada bettors the opportunity to place in-play wagers on all American football games taking place during the 2013 season.

Version 3.0 of the app also includes the availability of several different parlay cards.

The free app, which can only be used within Nevada borders, is available on iPhone, iPad and Android phones and tablets for anyone with an active data plan carried by AT&T, Sprint, Verizon, T-Mobile or Boost Mobile.

It can be registered at any of 75 full-service William Hill locations within the Silver State, with accounts able to be funded and withdrawn from at any full-service book, while deposits can also be made at a William Hill Mobile Sports Deposit Hot Spot, which can be found in any PT’s Tavern or Sierra Gold location.

William Hill US CEO Joe Asher said: “Our already popular parlay card offering becomes that much more attractive with its availability from anywhere in the state, and the ability to place in-play wagers at any point during any pro football game this season should be a hit with every football bettor.”
