US-regulated online casinos
Which state regulators license which casino brand, read off each regulator's own published list. 13 brands across 6 states, each state linked to the regulator’s own published list. These are licensed US operators, not the offshore crypto casinos covered elsewhere on the site — different licences, different rules, and they only take you inside a state that allows it.
Counts are states whose regulator names the brand on its own published list, not states it is live in — a few lists lag a rebrand, and each brand page says so where it applies. Rhode Island permits it and publishes no operator list at all, so nobody can appear there however widely they operate — in Rhode Island the lottery is both the regulator and the operator. Treat every number as a floor. A further 33 listings are venue names, licence-holding companies or B2B platform suppliers rather than brands you can sign up to; they stay on their state pages rather than being guessed into a brand.
