Prior to this week, the Mountain State went five months without mobile wagering after a dispute with Delaware North, Miomni and Entergaming led to the closure of BetLucky’s sports wagering operations.

The launch is DraftKings’ first mobile expansion since it introduced its live sports betting app in New Jersey last year, becoming the first mobile app available outside of Nevada.

Matt Kalish, Co-founder and Chief Revenue Officer at DraftKings, said: "We are thrilled to continue our DraftKings sportsbook expansion by getting our product into the hands of West Virginians."

DraftKings has also now gone live with NetEnt slots and table games in New Jersey after signing an agreement with the supplier earlier this year.

NetEnt holds a permanent license for the state and hopes to ultimately utilise DraftKings’ large fantasy database.

Erik Nyman, Managing Director of NetEnt, said: “DraftKings has a large player base and we are certain they will enjoy our portfolio of casino games.

"Players in the US can also look forward to a very exciting roadmap of games to be launched during the rest of the year and beyond."
