However, the casino can only ensure that every player fulfills this criterion by imposing a user registration process to verify their identity. Tropicana Casino has a license to operate, which allows them to offer real money games to residents of Pennsylvania that are at least 21 years of age and citizens of the United States. As a result, the law requires the casino to ensure that players that play there meet the regulatory requirements for real cash gambling. Tropicana Casino is a real-money betting establishment, similar to Atlantic City and Las Vegas.
