The operator’s updated mobile app, and accompanying website, is now available for players to use from anywhere in the Mountain State.
The sports betting app is built on William Hill’s proprietary platform, which includes in-play betting, multiple deposit and withdrawal options, live game casts and an in-app registration process.
The launch in West Virginia comes just ahead of the National Football League (NFL) season, which begins on 10 September.
West Virginia is now the fourth state William Hill offers its mobile sports betting app, following on from launches in Iowa, Nevada and New Jersey. Since establishing in 2012, William Hill US operates in more than 150 locations across 12 states.
Earlier this week, William Hill US CEO Joe Asher said betting on US sports in August was untypically busy this year due to the pent-up demand, after all major sport in the US, and worldwide, was suspended for several months in mid-March.
