In blackjack, the goal is to have a hand value closer to 21 than the dealer's without exceeding 21. Cards 2-10 are worth their face value, face cards are worth 10, and Aces can be worth 1 or 11. Each player and the dealer receive two cards, with the dealer showing one face-up card. Players can choose to hit (take a card), stand (keep their hand), double down (double their bet for one more card), or split (separate a pair into two hands). The dealer must hit on 16 or less and stand on 17 or more. If a player's hand is closer to 21 than the dealer's, or if the dealer busts, the player wins. A "blackjack" (Ace and a 10-point card) wins 1.5 times the bet.
