In Blackjack, the dealer has two cards: an upcard (face-up) and a hole card (face-down). If the upcard is an Ace or a 10-value card, the dealer checks for a Blackjack. If the dealer doesn't have a Blackjack, they play their hand according to house rules, usually hitting on 16 or less and standing on 17 or more, including a "soft 17" (Ace-6). The dealer’s hand determines the outcome of the round after all players have acted.
