To gain entry into a casino within the State of Nevada and gamble legally, you must be at least 21 years of age. Parents with children can pass through a casino (for example if they're on the way to an in-house restaurant), although anyone attempting to sit at a table or play the slots with a child/minor by their side will be asked to leave. So you can tour the decor and amenities with children. It might be an opportunity to talk with them about gambling.
