The legislation around online gambling in California is changing all the time but there are no laws that prohibit, regulate or ban any type of online gambling. However, betting on online casinos from within a state's borders is prohibited and may result in penalties.
At this time, the state does not appear to be ready to authorize online gambling or issue its official standpoint on online gambling legalisation. However, players have full access to social and sweepstakes casinos within the state.
