In Blackjack, the objective is to beat the dealer by having a hand value closer to 21 without exceeding it. Each player starts with two cards, which can be a combination of number cards (2-10), face cards (J, Q, K worth 10), and Aces, which can count as either 1 or 11. Players can choose to "hit" for additional cards or "stand" to keep their current hand. The game also allows for options like "double down" and "splitting" pairs. After players finish their turns, the dealer reveals their hidden card and must hit until reaching at least 17. Players win by having a higher total than the dealer without busting, with special payouts for achieving blackjack, which is an Ace and a 10-value card on the initial deal. The game emphasizes strategy, as decisions can significantly impact the outcome.
