It is completely legal to gamble roulette at whatever site you choose in the majority of jurisdictions. To be safe, it's generally a good idea to double-check your local legislation if you're not certain about this. Before registering anywhere, you should check where you may play since in some nations, for example, playing is only permitted on specific sites that are subject to regulation. However, gamblers can still frequently access foreign sites in most all nations where online gambling is legally permitted.
