To enter a casino, you typically have to be at least 18 years old, but some casinos have a minimum age requirement of 21. Age restrictions are in place to comply with legal regulations and ensure responsible gambling practices. It is important to carry a valid form of identification, such as a driver’s license or passport, when visiting a casino. Minors are strictly prohibited from gambling and are not allowed on the gaming floor. Casinos may also have specific rules regarding minors in non-gambling areas of the establishment. Always check the age requirements and rules of a casino before planning a visit.
