Named after the original bricks-and-mortar casino built in an old Philadelphia sugar refinery, the SugarHouse mobile app began offering online sports betting in New Jersey since late 2018. The operator is from the same Rush Street Gaming stable as Bet Rivers.
FanDuel also began as a fantasy sports competition operator. In 2018 it was acquired by Irish bookmaker Paddy Power Betfair, and within days opened its first retail sports betting outlet at New Jersey's Meadowlands Racetrack.
DraftKings started life as a daily fantasy sports (DFS) operator, launching DraftKings Sportsbook in New Jersey on August 1, 2018 - making it the first company to offer legal, online, mobile sports betting services. DraftKings also offers retail sports betting in partnership with casinos throughout the US.
