How to Play Blackjack

Basic Gameplay

Understanding how to play Blackjack  in a casino relatively straightforward. The game is played with one or more decks of standard playing cards. Each card has a value: numbered cards (2-10) are worth their face value, face cards (Jack, Queen, King) are worth 10 points, and Aces can be worth either 1 or 11 points, depending on which value benefits the hand the most.

Starting the Game

To start a game of Blackjack, players place their bets on the blackjack table casino. The dealer then deals two cards to each player and two cards to themselves, with one card face up (the “upcard”) and one face down (the “hole card”). Players then decide how to play their hands based on the card values and the dealer’s upcard. Understanding the blackjack table rules is essential for a smooth game.

Player Decisions

Players have several options during their turn:

  • Hit: Take another card from the dealer.
  • Stand: Keep their current hand and end their turn.
  • Double Down: Double the initial bet and receive exactly one more card.
  • Split: If the first two cards are of the same value, players can split them into two separate hands, each with its own bet.
  • Surrender: Forfeit half of the bet and end their participation in the round (available in some variations).

Dealer’s Turn

Once all players have finished their turns, the dealer reveals their hole card and plays their hand according to set rules. Generally, the dealer must hit until they have at least 17 points. If the dealer busts (exceeds 21), all remaining players win. If not, hands are compared, and the highest hand value wins. Familiarize yourself with a blackjack guide to improve your skills.

How to Count Cards in Blackjack

Basics of Card Counting

Card counting is a strategy used to gain an advantage by keeping track of the high and low cards remaining in the deck. While it doesn’t guarantee winning, it can significantly increase the odds in the player’s favor. The basic premise is to keep a running count of the cards dealt, assigning values to different cards.

Running Count and True Count

  • Running Count: The player assigns a value to each card dealt. Typically, cards 2-6 are counted as +1, 7-9 as 0, and 10-Ace as -1. The running count is the sum of these values.
  • True Count: To account for multiple decks, the running count is divided by the number of decks remaining. The true count gives a more accurate picture of the deck’s composition.

While card counting is legal, casinos discourage it and may take measures to identify and ban skilled counters. Knowing how to play blackjack in a casino can enhance your experience.
