Some prominent jurisdictions where online gambling is legal and regulated include the United Kingdom, Malta, Gibraltar, Isle of Man, and Alderney. These countries have established licensing authorities that oversee online gambling operators, ensuring consumer protection and fair play.

Aside from it being illegal, you run several risks by betting with an offshore sportsbook. Unlike legal sportsbooks in the U.S., offshore books aren't regulated by government agencies, which means they aren't subject to regular checks and controls.
