Top Licensed Online Casinos in Delaware 2026

Delaware became one of the first three US states to legalize online casino gaming in 2012 and launched real-money iGaming in November 2013, years ahead of most of the country. The Delaware Lottery operates the market under a single-vendor model with revenue shared among Bally's Dover, Delaware Park, and Harrington Raceway. After more than a decade with 888 Holdings as the technology provider, the Lottery transitioned the entire iGaming platform to Rush Street Interactive's BetRivers in late 2023. The change dramatically expanded the game library and drove iGaming adjusted gross revenue to $62.6 million in RSI's first year, with about $37.3 million in tax receipts, nearly four times the take under 888. Co-branded BetRivers casino apps run under each of the three racino brands but share a single player pool. Players must be 21+ and within Delaware state lines.
