Want to learn how to play blackjack online? You’re in the right place!

We’ve got you covered with our comprehensive guide on how to play this casino classic.

Blackjack, also known as twenty-one and Vingt-et-Un, is one of the most popular card games at land-based casinos and is just as popular at online casino sites. It’s relatively easy to get to grips with, which makes it perfect for beginners but, if you play your cards right, blackjack also offers the chance to win big!

While there’s no foolproof way to guarantee a win when playing blackjack, understanding the game inside out can help you make better decisions and set you on the right path to beating the house. Ready to learn more about playing online blackjack? We’ve covered everything you need to know to start your blackjack adventure.

Blackjack Basics

The concept of blackjack is pretty simple: get as close to 21 as possible without exceeding it. You’ll be playing against a virtual dealer, who’s also aiming to reach 21, and whose hand you want to beat. Let’s run through everything you know about playing blackjack.

Card Values

Blackjack card values are pretty simple to understand.  The value of cards 2 to 10 is their pip value and face cards (jack, queen and king) are worth 10. An ace can be worth 1 or 11, depending on which value most helps your hand, but using it as an 11 is known as a soft hand.

Betting Options

You have a number of options in a blackjack game, and each move has different consequences.

  • Stand – Standing means you wish to stick with the hand you’ve been dealt and you won’t be dealt any additional cards;
  • Hit – Hitting is a request for another card in addition to your original hand. This action is useful if you’ve been dealt two low value cards in your first hand;
  • Split Pairs – If your two cards are identical, you’ll be able to split them to play as separate hands, giving you two chances to beat the dealer. This move isn’t available to blackjack dealers;
  • Double Down – This doubles the initial bet, committing to stand after receiving just one more card in your hand. Blackjack dealers don’t have the option to double down;
  • Surrender – In some games, if you’ve been dealt a bad hand, you can choose to surrender. This means you’ve accepted you won’t beat the dealer and you’ll be able to recoup half of your bet;
  • Bust – No one decides to bust, but this is what happens when your total card value exceeds 21. Going bust means you’ll instantly lose the bet.

Blackjack in Play

Here’s how a standard game of online blackjack might unfold:

  • Bets are made – Bets are placed before any cards are dealt. Betting tables will usually have maximum wager limits, which will vary between games and casinos.
  • Cards are dealt – Both your cards will be dealt face up. The dealer’s first card will be face up, but neither of you will be able to see the second.
  • Check for naturals – You’ll check for a natural blackjack— an ace and any card with a value of ten— to hit 21 straight away. The dealer can only check for a natural if his faceup card is a ten-card or an ace. You’ll instantly be paid 1.5 times your initial bet if you land a natural blackjack. If both you and the dealer have a natural blackjack, neither you nor the casino wins and your bet will be returned. This is known as a push.
  • Actions are decided – If you don’t have a natural 21, and the dealer cannot check for one, you’ll continue play in an attempt to get as close as possible without exceeding the number. From here, you’ll decide whether to split, double down or hit until you stand or bust.
  • Winnings are paid out – Once you stand, or you or the dealer busts, the results of the game will be displayed on the screen and your winnings paid out. You’ll win if your hand is higher than the dealer’s and doesn’t exceed the limit of 21.

How to Beat the Dealer

When playing blackjack, your opponent is the house or the dealer. Which begs the question, how do you beat them? As we’ve already touched on, the goal is to get the hand closest to 21 without going bust — essentially, that’s all you need to do to beat the dealer. 

There are a few ways you can win a hand of blackjack:

  • Your first two cards make a natural blackjack and you automatically win, assuming the dealer does not also hold a blackjack.
  • The dealer stands and your hand is closest to 21. 
  • You stand, and then the dealer hits and goes bust.

If both the player and dealer have the same hand value, it’s a tie or ‘push’ and your stake is returned. 

If you’re looking for tips and tricks to improve your odds of beating the dealer, there aren’t any secrets or shortcuts. But you can apply basic strategy to ensure you make the best decisions according to the maths. While it depends on the specific rules of the blackjack variant you’re playing, it’s worth learning what to do in certain situations. 

Some elements of blackjack strategy which will help you beat the dealer include:

  • Always hit hard 11 or less;
  • Always stand on hard 17 or higher;
  • Always split 8s and Aces;
  • Never split 5s or 10s;
  • Always stand on soft 19 or higher.

How to Lose to the Dealer

While it’s a situation you’ll be wanting to avoid, losing to the dealer is inevitable when playing blackjack. The dealer wins in a number of situations:

  • The player hits and busts as their hand has a value above 21;
  • The player stands and the dealer gets a hand closer to 21 without going bust;
  • If the dealer’s up card is a 10, face card, or ace, they can peek at the hole card. If they have a natural blackjack, they flip over the hole card and automatically win the hand. 

If your hand is worth the same as the dealer’s, it results in a push and your stake is returned. Keep in mind some variants of blackjack feature the ‘push on 22’ rule, where the round ends in a push if the dealer’s hand is worth 22, even if you have a blackjack. 

How the Blackjack Table is Set Up

Most RNG and live dealer blackjack games emulate the real thing you’ll find in a brick-and-mortar casino. The table is usually a semicircle covered in green felt. The dealer sits along the straight edge of the table, with player seats positioned opposite around the curved edge. Within easy reach of the dealer is the shoe, used for dealing cards, and the chip tray. 

Each player’s position is marked clearly on the table. This is where they can place their betting chips and where their cards will be dealt. Some blackjack games let players bet on more than one hand per round, with each hand given its own spot on the table. 

If the game features side bets such as Insurance or 21+3, these will also be marked on the table. In online blackjack, this is all taken care of for you — your actions and betting are controlled via the interactive interface. 

Blackjack Odds

The exact odds for a blackjack game will change depending on the variation you’ve chosen and how many decks are in use. For a standard game, blackjack pays out at 3:2, which means you’ll receive 1.5 times the amount of your bet if you win. So let’s say you’ve placed a bet of £5 and you successfully beat the dealer- you’ll receive £7.50 as a payout.

House Edge

Each blackjack variation features slight differences in rules and gameplay, which in turn will impact a player’s chance of beating the house. However, ultimately, the house edge means a casino will always have a slight advantage when you’re playing blackjack over a longer period of time. This means that, while you might seem to have the hot hand, your winning streak won’t last forever. These are the house edge percentages for a standard blackjack game:

Number of Decks House Edge
Single Deck -0.03%
Two Decks +0.25%
Four Decks +0.38%
Six Decks +0.42%
Eight Decks +0.44%

Other Blackjack Scenarios

Alongside a simple win or loss, there are a few other situations that can occur in blackjack, some of which are dependent on the rules in play. Let’s take a look. 

Insurance and Even Money

Insurance or even money is a side bet allowed in some games of blackjack. Essentially, it’s a bet that the dealer has a blackjack and thus will beat the player — hence the name ‘insurance’, as the payout usually covers the stake so the player breaks even.

In games where insurance is available, it’s only offered when the dealer’s up-card is an ace, and the maximum bet is usually half the player’s stake. If the dealer does indeed have a blackjack, the insurance bet is paid. If they don’t, the stake is lost — but you’ll be able to continue playing the hand as normal. 

While the insurance bet can seem like an enticing proposition, taking this wager is usually a losing strategy in the long run if you’re looking for the best value.

Dead Hands

A dead hand has a few definitions in blackjack. Typically, it refers to any hand that’s no longer in play, usually due to busting. Hands or entire rounds can also be declared ‘dead’ if they’re voided due to dealer mistakes or a rule being broken. This won’t usually occur in online blackjack. 

Dead hands can also refer to situations where every player at the table has gone bust before the dealer reveals their hole card. At this point, they’ve automatically won anyway — but they’ll flip over the card before the next round begins. 

Side Bets

Many blackjack games involve side bets where players can wager on specific outcomes. These bets are paid independently of who wins the round, so you could lose the main bet but still walk away with a win. 

Here are some popular blackjack side bets:

  • 21+3 is based on poker rankings. It combines the player’s two cards with the dealer’s up card, with payouts for things like straights, flushes, and three of a kind;
  • Perfect Pairs is a bet that the player’s first two cards will make a pair. The payout is based on the type of pair — mixed, coloured, or suited;
  • Buster Blackjack involves betting on how many cards the dealer will draw before busting;
  • Royal Match is a bet that the player’s first two cards will be the same suit, or a suited King and Queen.

Online Blackjack Variations

Depending on which version of blackjack you play, you’ll encounter a number of different rules. These all have an effect on the house edge — it’s worth taking into account which game you play if you’re looking for the best RTP.

Doubling After Splitting

In certain situations such as Aces or 8s, players will want to split these pairs into two separate hands. When the ‘double after splitting’ rule is in effect, the player can then double their bet on one or both the new hands, should they receive a favourable card. 

Re-Splitting Aces

In basic blackjack strategy, it’s advised to always split aces. The reason being you have a good chance of hitting 21, requiring just a 10 or face card to do so. But what if you split your aces into two hands, only to be dealt another ace? Some blackjack games let players split these aces again, creating a third hand.

Early Surrender

When it’s available, the early surrender rule lets players exit the round early and reclaim half their stake. A bit like insurance, it’s offered when the dealer’s up card is an ace, giving players a chance to minimise their losses on weaker hands.

6 to 5 Blackjacks

In standard blackjack, naturals (an ace plus a 10 or face card) are paid at 3-to-2, with all other winning hands paid at even money. But some variants of blackjack pay naturals at lower odds of 6-to-5. This rule is unfavourable for players and leads to a steeper house edge. 

Deck/Shoe Penetration

In blackjack, penetration refers to how much of the deck or shoe is dealt before it’s reshuffled. It’s expressed as a percentage — so 50% penetration in a single-deck blackjack game would mean the cards are shuffled once 26 have been dealt. 

Deeper penetration is beneficial when counting cards, as players can get a better idea of the remaining deck once more cards have been dealt. 

Blackjack Strategies – Managing Your Bankroll

Blackjack is favoured by many thanks to the fact it’s one of the few casino games where there’s an element of skill. Along with basic strategy, some players might want to consider a betting system to help them manage their bankroll. 

Let’s be clear — no system or strategy is a guaranteed way to beat the house, and anyone claiming otherwise is lying. But betting strategies can add another angle to your gameplay or get a few more hands out of your budget. 

Some of the most popular blackjack betting strategies include:

  • Martingale – With this system, players start at a base stake and double it every time they lose, resetting once they win. It works on the basis that you’ll recoup any losses and net a small profit when you do win;
  • D’Alembert – This betting strategy works a bit like the Martingale, but by adding a base betting unit following a loss, rather than doubling your stake. It’s a better option for those with a smaller budget, as the numbers won’t get quite as large when you hit a bad streak;
  • Fibonacci – This system uses the Fibonacci sequence to decide how many base betting units to wager. Each time you lose, you move along one number in the sequence. Each time you win, you move back two numbers.

Downfalls of Blackjack Betting Strategies

While betting strategies can be an entertaining way to gamble, they’re not foolproof. Progressive systems like Martingale and D’Alembert can quickly run into problems if you hit a longer streak of losses — you might find the required bet is more than the table limits, or exceeds your remaining bankroll.

In any case, it’s essential to stay within your limits and always gamble responsibly. We recommend setting a budget before you play, and practising in demo mode or free play before trying out a new betting system.

Live Dealer Blackjack

Whether you’re looking to play blackjack, roulette or slots, many top UK casinos offer live casino games. Live dealer blackjack is the most immersive and exhilarating blackjack experience, as you’ll be playing in real time conditions, with a game controlled by a live croupier. Some casinos even allow live casino players to interact with dealers using through a chat room, which allows players to enjoy the social aspect of playing blackjack, usually found at brick-and-mortar casinos. All things considered, this is by far the most realistic casino experience available online.

These casinos are held to high standards by governing bodies like the UK Gambling Commission, which ensures blackjack games remain fair. Animated games use random number generator technology (RNG) to provide players with a fair and random result every time, while live blackjack games are run by trained and unbiased casino dealers.
