Four regulatory models
Licensed and open: the state issues local licences, taxes operators and enforces player protection — the United Kingdom, Denmark, Spain, Portugal, Malta and Ontario work this way. State monopoly: one government-owned operator is permitted and foreign sites are blocked or restricted, as in Norway and Finland. Prohibited: online gambling is banned outright, as in much of the Gulf and large parts of Asia. Grey: no specific law addresses online play, so offshore operators serve the market without local licensing.
A crucial distinction runs through all of them: most gambling law targets the operator, not the individual player. Prosecutions of ordinary players are rare almost everywhere, but that is not the same as the activity being legal, and it is not a defence.
