Retail Casino Age Requirements\n\n Usually, properties set the age at 21 to comply with state law. Additionally, 21 is the legal drinking age in most states, so casinos set their minimum to allow liquor consumption on the property. However, tribal casinos often have more wiggle room with the legal gambling age.
In Blackjack, everyone plays against the dealer. Players receive all cards face up and the dealer's first card is face up and the second is face down. The object of the game is to get closer to 21 than the dealer without going over 21. If a hand goes over 21, it is called a bust or break and the wager is lost.
