Available as of yesterday (11 March), players in the state will be able to wager on a wide range of sports and access a selection of bet types, including live, in-play wagering.
New customers who make a deposit will also benefit from a risk-free sports bet of up to $2,021, with players able to access the app and website from anywhere inside Tennessee.
“As we head into one of the most exciting times of the year for sports fans, the William Hill app will make March moments even more interesting for Tennessee bettors,” William Hill US president of digital Kenneth Fuchs said.
“We will have thousands of markets available, including for your local favourites, live in-game betting, and daily promotions and bonuses for players.”
Tennessee becomes the 12 US jurisdiction in which William Hill has launched its online and mobile sports betting products.
