It depends on where you are. In the US, sports betting is fully regulated in 38+ states; online casino is live in 7 states. Outside the US, most of Europe, Canada, much of Latin America, and parts of Asia and Africa have regulated frameworks. We only feature licensed operators in jurisdictions where they're legal — read each review for state and country availability.
Five-pillar methodology: bonus value (after rollover), payout speed, market depth and pricing, app/desktop UX, and trust score (license, complaints, financial backing). We test each operator with real money and re-score quarterly. Full breakdown on our methodology page.
We earn affiliate commissions when readers sign up via some operator links. Commission has zero influence on rankings — operators we don't recommend can't pay to be added. We disclose every paid relationship.
FanDuel and DraftKings consistently rank highest for new bettors thanks to clean UX, generous welcome offers, and accessible betting types like Same Game Parlays. See our full comparison.
