The statewide program is administered by the California Gambling Control Commission and the Bureau of Gambling Control, and encompasses all “card rooms” in the state.
Card rooms are casinos that are regulated by the state (i.e. not on sovereign tribal land), and are most distinguished by the fact that they do not have slot machines.
Mailing in a single form allows you to exclude from all card rooms in the state.
Each tribal casino has its own regulatory agency, usually called a “tribal gaming commission,” and generally each tribal casino will have its own self-exclusion program regulated by its own gaming commission.
