How old must someone be to play in the casinos?
Mississippi law requires at you must be at least 21 years old to play in a casino. If you look young, you can expect security at the casino’s entrance will check your identification. You may also receive a stamp on your hand. If you appear to be young, you may be further asked to provide your ID while playing by a dealer, security, or a floor supervisor. People younger than 21 can enter the casino to go to a restaurant when escorted by an adult if they must cross the casino floor, so there is no reason not to take children to the many great restaurants available.
