Rules of Blackjack

Blackjack is a captivating game that combines strategy, probability, and quick decision-making. In this in-depth article, we will provide a thorough explanation of the game’s rules and walk you through each stage of a round, from start to finish. Whether you are a beginner or an experienced player, understanding the rules is essential for maximising your chances of winning. So, let’s dive into the world of Blackjack and explore its intricacies.

The Objective of Blackjack

The primary objective of Blackjack is to obtain a hand with a higher value than the dealer’s without exceeding 21. When you place your initial wager, you win if the total value of your cards surpasses the dealer’s hand. However, if your hand exceeds 21, known as going “bust,” you lose your wager.

The Basics of Blackjack

To play Blackjack, you’ll need the following:

  1. A standard 52-card deck, although up to 8 decks may be used.
  2. A dealer who manages the game.
  3. A minimum of 2 players, typically up to 7.

It’s important to note that each variant of Blackjack has its own set of rules and payout odds. Some popular variations include Spanish 21, Switch, Free Bet Blackjack, and Super Fun 21. While each variant has its own unique features, the overall flow of the game remains relatively consistent.

Understanding the House Edge

The house edge in Blackjack can range from 0.28% to 0.5% depending on the rules implemented by top online casinos in the UK. However, with a mathematically perfect strategy, players can minimise the house edge and increase their chances of winning.

Blackjack as a Card Game

One of the reasons Blackjack is such an appealing card game is its simplicity. Anyone can learn the basic rules and apply a basic strategy to play for fun. You don’t need to visit a casino to test your skills; you can enjoy Blackjack as a card game with your family and friends at home.

Home Rules for Blackjack

When playing Blackjack outside of a casino setting, there are slight rule variations. Since there is no permanent dealer, players take turns acting as the dealer. Additionally, you have the flexibility to customise your sessions with alternative rules such as resplitting, surrendering, and dealer peeks. Practicing with friends not only adds fun to the game but also helps develop a keen eye for its subtleties. You can experiment with different strategies and determine what works best for you.

Understanding Card Values

Each card in Blackjack has a specific value assigned to it. Number cards hold their numerical value, while face cards (Jack, Queen, and King) are each worth 10 points. The ace is the most valuable card as it can be counted as either 1 or 11 points, depending on the player’s preference.

For example, if your hand’s total is below 21 but higher than the dealer’s, or if your cards precisely add up to 21, your bet is a winner. However, if the dealer also has a Blackjack hand, your stake is returned. It’s worth noting that in Spanish 21, a hand totaling 21 points wins even if the dealer also has a hand with 21 points.

Stages of a Blackjack Round


To succeed at Blackjack, you need to make wise bets and decisions while considering all possible outcomes. A solid understanding of the game’s rules will help you overcome the built-in advantage of casinos. Let’s take a closer look at each stage of a round to familiarise ourselves with the process.

Stage 1: The Initial Deal

At the beginning of a round, players place their bets within the table’s designated limits. The dealer then shuffles the cards, cuts the deck, and distributes two cards to each player. All cards are dealt face-up, except for the dealer’s last card, which remains hidden until all bets are settled.

This face-down card is known as the “hole card.” In single-deck versions of Blackjack, cards may be dealt face-down, but this rule is seldom applied in modern casinos that typically use multiple decks.

Stage 2: Player Action – Which Way to Go?

After receiving their cards, players assess their hands and make decisions while the dealer keeps their second card face-down. Starting from the left, the dealer prompts each player to choose their action. Will they stand, satisfied with their current points, or request another card to get closer to 21? It’s important to remember that the goal in Blackjack is to avoid exceeding 21 and going bust. Since the dealer has an advantage by acting last, you could potentially lose your bet before the dealer even reveals their face-down card.

Stage 3: Dealer Action – Closing Bets

Once all players have made their decisions, the dealer reveals their hidden card, and all bets are closed. Blackjack rules dictate that dealers must follow specific guidelines. If their total points are below 17, they must draw another card and continue drawing until their hand reaches 17 or higher.

When the dealer has an Ace, it is counted as 11 points to bring the total to 17. The actions of collecting bets and dealing cards remain relatively consistent across different Blackjack variants. If you choose to play online at live dealer casinos, you’ll notice that Live Blackjack follows a similar format. Let’s explore what happens when the dealer finishes totaling their points.

Stage 4: Bets Settle

The final step in a round is the settlement of bets. At this point, the dealer reveals their hole card and compares their total with the other players at the table. If you went bust, your bet is settled immediately. According to the rules of Blackjack, if the dealer busts and no players do, all players’ bets are winners.

However, if the dealer’s total is 21 or less, only players with a higher total than the dealer’s receive payouts. Players with a lower total than the dealer lose their wagers. Once the bets are settled, the dealer reshuffles the decks and proceeds with the next round, following the same pattern.

Player Options in Blackjack

As a player, you have several options available to you during the game. Let’s take a closer look at each option and its strategic implications.

1. Hit

If you believe your hand is weak and your points are too low, you can request another card by choosing to hit. In land-based casinos, you would tap the table to indicate your desire for another card. In online Blackjack, a dedicated button is available for this action. You can ask for as many cards as you like, as there is no specified limit.

However, be cautious not to exceed 21 and go bust. In certain Blackjack rules, if the dealer’s up-facing card is an Ace, you may be offered a side bet called insurance. This bet acts as a form of protection against the possibility of the dealer having a Blackjack hand. You can stake half of your main bet, and it pays out at 2/1 odds.

2. Stand

If you are satisfied with your current points and don’t wish to receive any more cards from the dealer, you can choose to stand. This decision is essential to prevent busting. For instance, if you believe the dealer is likely to go bust, it’s advisable to stand and let the dealer take the risk.

3. Double Down

Doubling down allows you to increase your wager when you believe your hand is stronger than the dealer’s. After receiving your initial two cards, you can place an additional bet of the same value and receive one extra card. It’s important to note that doubling down is not the same as the Martingale Blackjack strategy, where you double your stake after each loss. Doubling down in Blackjack is an option available only after you receive your initial cards.

4. Split

When you are dealt a pair of cards, splitting allows you to create two separate hands. For example, if you receive a pair of 10-valued cards, like two Jacks, it is beneficial to split them and play with two hands. You redirect your initial stake to one hand and place an equal wager on the other hand.

From that point onward, you are treated as two separate players, and you must make decisions for each hand individually, starting from the left. The wagers on each hand are settled independently. In some variations of Blackjack, resplitting is allowed, which means you can further split a pair of cards until you have up to four hands. Certain rules even enable unlimited resplitting.

5. Surrender

Surrendering is an optional Blackjack rule that allows you to fold your hand and forfeit half of your stake. There may be instances where you are dealt a particularly poor hand, and surrendering can be a wise decision.

For example, if you have a 2 and a 3, which is considered a weak hand, you can choose to surrender. By doing so, you will receive half of your bet back and skip the current round, hoping for better cards in the next round.

By now, you have gained a solid understanding of the rules of Blackjack. Here’s a quick recap of what you’ve learned:
