The app is available for Android and iPhones. Like other sports betting apps, it isn’t available in the Google Play store, though. The NV Sports Book app offers another casino group to check out for the best lines. Besides different lines, there doesn’t seem to be anything new or different with this app as opposed to all the others. The Nevada Sports Book app software is the same as the William Hill app. You can download the Nevada Sports Books app for free, but can't use it until you load your account with money. A minimum of $100 is required.
