The legal age for gambling in Las Vegas is 21. Casino floors and other gambling areas are restricted zones for anyone under the legal age.
Although a visitor under the age of 21 may not stop or sit on a casino floor, many resorts allow minors to walk through gaming areas in order to access other facilities. This may include restaurants, shop, movie theaters and hotel rooms. Some resorts have particularly strict policies related to minors, not allowing anyone under the age of 18 to enter their premises unless registered as a guest at the hotel or as a participant in specific activities or events.
