Blackjack Poker Card Game


Blackjack, also known as Twenty-One, is a renowned card game offering simplicity, excitement, and strategic depth. Whether played by experts with high-level strategies or casual participants enjoying a good game, Blackjack provides favourable odds for players.

Originating in 18th-century France as Vingt-et-Un, it gained popularity during World War I, and is now a staple in every American casino. In this game, players compete against the house, represented by the dealer who manages card dealing, shuffling, and bet handling.

In the casino version, there’s a permanent dealer, while the casual version allows players to take turns in this role, adding more fun and twists to the classic card game.

The Pack

Most casinos use a standard deck of 52 cards, with several decks often shuffled together. The game with six decks (312 cards in total) is relatively common. The dealer also uses a blank plastic card that is placed near the bottom of the cards. This card doesn’t get dealt, but is used as a signal that it’s time to reshuffle the cards.

When using four or more decks, the dealer deals cards from a shoe, which is like a box that lets the dealer take out face-down cards one by one without holding multiple packs in hand.

Objective of the Game

In Blackjack, the objective is to outscore the dealer without surpassing the total card count of 21. Some people might have different ideas about the game, but at its core, get your card total close to 21, and make sure it’s higher than what the dealer has to win.

How to Beat A Dealer?

To win against the dealer in Blackjack, you have a few ways:

  1. Get a hand value that’s higher than the dealer’s without going over 21
  2. Wait for the dealer to go over 21 by drawing cards
  3. Get a hand value of 21 with your first two cards when the dealer doesn’t

How to Lose to a Dealer?

To lose to the dealer in Blackjack:

  1. Your hand value goes over 21
  2. The dealer ends up with a hand value greater than yours at the end of the round

Unlike poker, where you compete against other players, in Blackjack, your main focus is on beating the dealer. The other players at the table don’t affect whether you win or lose; it’s essentially a one-on-one competition between you and the dealer.

How Do You Find a Hand’s Total Value?

In the game of Blackjack, a standard deck of 52 playing cards is used where:

  1. Number cards (2 through 10) count at face value
  2. Face cards, i.e., Jack, Queen, and King, all count as 10
  3. Aces can be counted as 1 or 11, depending on which value benefits the hand more
  4. The suits of the cards don’t matter

How to Play Blackjack?

Blackjack is a popular card game that’s easy to learn. The goal is to have a hand value closer to 21 without going over to beat the dealer.

  • Each player is dealt two cards, and face cards are worth 10 points, while number cards are valued at their face value. Aces can be worth 1 or 11 points, depending on what benefits the hand
  • Players can choose to “hit” for another card or “stand” to keep their current total
  • The dealer then reveals their hidden card, and the winner is determined. If a player’s card value total goes over 21, they bust and lose the round
  • An Ace combined with a 10-value card form the best hands. It’s a thrilling game of calculations and strategy, making it a casino favourite

Special Scenarios

Special scenarios add thrill to the Blackjack game; here the game gets an exciting twist. From unexpected challenges to fresh opportunities, these unique situations add a new dimension to this classic card game.


In the last couple of decades, Blackjack side bets have gained popularity. While insurance is the only side bet found on every Blackjack table and crucial for card counters, there are now hundreds of other side bets available, adding diversity to the game.

Non-Insurable Dealer Blackjack

In some Blackjack games, the dealer can have a blackjack without giving players the option to take insurance or even money. If the dealer’s face-up card is a ten, they immediately check their face-down card before players make any moves. If the face-down card is an ace, the dealer has a blackjack, and they win all bets on the table except for player blackjacks, which result in a tie. Insurance is only available when the dealer’s visible card is an ace.

Dead Hand

If all players at the Blackjack table exceed 21 points before the dealer plays their hand, it’s called a “dead hand.” In this case, the dealer reveals their face-down card and then collects and discards the cards. Since all players have already lost, there’s no need to proceed with playing out the dealer’s hand.

Blackjack Rules

In Blackjack, the game often uses 6 or 8 decks of cards shuffled in a card dispensing device called a “shoe.” While single- and double-deck games exist, they’re less common. We’ll focus on the rules of the typical 6-deck version. Here’s a quick rundown of how a round of Blackjack works:

  1. Deal: The dealer starts with the player on their left (first base). Each player, including the dealer, receives two cards. Players are dealt face-up cards, while the dealer has one face-up card and one face-down card. This initial deal sets the stage for strategic decision-making
  2. Player’s Turn: Players decide how to play their hands based on the value of their cards. Options include “hit” (take another card), “stand” (keep the current hand), “double down” (double the bet and take only one more card), and “split” (if dealt two identical cards, split them into separate hands). The goal is to reach a hand value close to 21 without going over
  3. Dealer’s Turn: Once all players complete their turns, the dealer reveals the hole card. The dealer must hit until their hand reaches at least 17 and stand thereafter. The dealer’s decisions are rule-bound and not influenced by strategy or player decisions.
  4. Winning and Losing: If a player’s hand exceeds 21, they bust and lose the bet. If the dealer busts or has a lower hand value, players win. A player wins when they don’t bust and have a hand closer to 21. Ties result in a “push,” and players get their bets back
  5. Blackjack (Natural 21): If a player is dealt an Ace and a 10-value card as their initial two cards, it’s a “blackjack” or a “natural 21.” This usually pays 3:2 unless the dealer also has a blackjack, resulting in a push
  6. Insurance: Players can opt for insurance if the dealer’s up card is an Ace. This side bet pays 2:1 in case the dealer has a blackjack. However, it’s generally considered a risky bet and is not always recommended
  7. Reshuffling and New Round: After a round is completed, the cards are reshuffled, and a new round begins. The game continues with players placing their bets and receiving new hands

Remember, mastering Blackjack involves understanding basic strategy, knowing when to hit or stand, and managing your bets effectively. Practice and familiarity with the rules will enhance your decision-making skills in this popular card game.

Blackjack Rule Variations

In Blackjack, the game played can vary due to different rules. Some popular variations are:

Doubling After Splitting (DAS)

Some casinos let you double down on a hand after splitting it. This is advantageous for players, but not all casinos allow it.

Re-Splitting Aces (RSA)

This rule allows players to split a pair of aces, and if another Ace is dealt, they can split again, creating up to four hands. While this rule benefits players, casinos often limit it by allowing only one additional card on each ace. Doubling or taking extra cards is usually not allowed to balance the advantage.

Early Surrender

This is a dead rule, not seen in U.S. casinos since the 1970s, that allows players to surrender before the dealer checks for blackjack or offers insurance. It used to favour players greatly, even giving a small edge to perfect strategy players without card counting. It became extinct because of its player-friendly nature.

6 to 5 Blackjacks

In some casinos, the usual 3 to 2 payout for Blackjacks is reduced to a less favourable 6 to 5. This increases the house edge, taking more money from players and rendering card counting less effective. Not all tables in a casino may have this rule, so it’s important to check the felt rules before sitting down.

CSM Blackjack

Some casinos use Continuous Shuffling Machines (CSM) in Blackjack, which shuffle cards continuously during play. Unlike traditional games with a discard tray, a CSM never ends the shoe, making card counting impossible and unfavourably impacting basic strategy players.

Single Deck versus Multi-deck

Increasing the number of decks in Blackjack generally raises the house edge. However, the impact varies as other rules differ; for instance, a single deck may have limitations like no doubling after splitting, while an eight-deck game might offer more player-friendly rules, affecting the overall house edge.

Deck/Shoe Penetration (PEN)

PEN refers to the percentage of cards dealt from a shoe before reshuffling. Casinos often insert a cut card to signal the end of the shoe; however, they may cut off several decks to hinder card-counting profitability. For card counters, the depth of penetration significantly influences the game’s outcome, as a shallower penetration limits their advantage.

Basic Strategy

In Blackjack, playing optimally involves considering both your own hand and the dealer’s up card. Adjusting your strategy based on the dealer’s upcard is a fundamental aspect of maximising your chances of winning in the game.

Against a Strong Dealer Upcard (7, 8, 9, 10, or Ace):

  • Keep drawing until a total of 17 or more is reached

Against a Weak Dealer Upcard (4, 5, or 6):

  • Stop drawing at a total of 12 or higher
  • Avoid taking a card if there’s a risk of going bust, hoping the dealer will exceed 21

Against a Neutral Dealer Upcard (2 or 3):

  • Stop drawing with a total of 13 or higher

Soft Hand Strategy (Ace in hand):

  • Keep hitting till a total of 18, at least

Doubling Down:

  • Double down on a total of 11
  • With a total of 10, double down unless the dealer has a 10 or an Ace
  • With a total of 9, double down only if the dealer’s card is fair or poor (2 through 6)

Pair Splitting:

  • Splitting a pair of Aces or 8s is beneficial
  • Do not split identical 10s, a pair of 5s, or a pair of 4s
  • Generally, split 2s, 3s, or 7s unless the dealer has an 8, 9, 10, or Ace
  • Do not split 6s unless the dealer’s card is poor (2 through 6)
