Blackjack is a casino game where you play against the house. Also known as a banking game, the main aim is to score closer to 21 than the dealer without exceeding that value. If your hand goes over 21, you have busted, and you lose your bet immediately, regardless of the dealer’s hand. Or if the dealer’s hand is higher than yours at the end of the round, you lose. You can beat the dealer by drawing a hand value of 21 with your first two cards when the dealer does not. You also beat the house if the dealer busts or if you draw a hand higher than the dealer’s hand value.

Blackjack is one of the few casino games where strategy can make a difference. By considering all the possible actions and choosing the move that statistically gives you the greatest expected return, you can impact your chances of winning. As such, the better you know the rules, options and features of blackjack game variants, the better your chances.

The traditional blackjack table has a semi-circular shape. It usually has a surface made of green felt with various markings embedded on it. You will see the table limits and game payouts printed on the table. You will also see the game rules, namely the fixed rules the dealer must follow when drawing cards. On the table, you will see a position where the player can place their bet. Various chip sizes are displayed on the bottom of the table, and the player selects the size of the bet by clicking on the chip, then clicking on the bet position to make the wager.

The position assigned to the dealer is located at the top of the table facing the player. To the dealer’s left is the card shoe, where cards are dealt from. To the right is the discard tray, where discarded cards are moved to once a game round is completed. Once bets have been placed, the player’s cards are dealt face up just above the betting spot. The dealer’s cards are dealt with an up card and a hole card, which is not revealed until the player has completed their moves. If the dealer’s up card is an ace, players are given the option to place an insurance bet. When playing blackjack online, the actions the player can take are highlighted on the screen, with options to hit, stand, split or double as appropriate.

Given the wide range of blackjack variants that you can play online, there are some variations to the table layout that can be found. If the game variant has optional side bets, you will also see a section marked where you can place the additional bet. However, the basics usually stay the same, so it is quite easy to adjust to the table variant.

You should see the payouts for side bets displayed on the table since those vary greatly. Many online variants offer multi-hand gameplay. As such, you can place numerous bets by clicking on the other player betting positions on the table.

Understanding the value of the cards in blackjack is pretty straightforward. The number cards, 2 – 10 score their respective value. The face cards, Jack, Queen and King count as 10. The ace, on the other hand, can count as either 1 or 11. The ace’s value will always work in the favor of the player.

When a hand includes an ace, it is known as a soft hand, as there are two possible scores for the card. Most online games automatically assign the ace a value giving you the best possible hand. A hand with no aces has only one possible score and is known as a hard hand – you don’t have a choice there.

Once the cards have been dealt, the player has various options of how to play their hand. If you are satisfied with your cards, you can stand. Alternatively, you can hit and receive an additional card. You can hit as many times as you like, provided the total value of the cards does not exceed 21.

Hit and stand are the two basic options, yet there are other possible moves depending on the two cards you have been dealt, including splitting and doubling down. Also, if the dealer’s up card is an ace, you will have the option of taking insurance against a dealer blackjack.

  • Hit: To ask the dealer for an additional card. If the additional card makes the total over 21, the player busts and loses their wager.
  • Stand: To stop asking for more cards, ending the player’s turn.
  • Split: When the player is dealt two cards of the same value, you can place an additional wager of equal value to the original bet and play the cards as two separate hands.
  • Double: After the player’s cards are dealt, you can place a wager, equal to the original bet. You will then draw one more card only to your hand.
  • Insurance: When the dealer’s up card is an ace, you can place an insurance bet against a dealer blackjack. A payout of 2:1 is made if the dealer does have blackjack, otherwise the bet is lost.
  • Surrender: An option not available in all blackjack variants, it allows the player to forfeit a weak hand that is unlikely to beat the dealer, losing just half of the original wager.

Whilst players have the freedom to choose what actions to take with their hand, the dealer, on the other hand, must play according to set blackjack rules. This ensures consistency when playing the game of 21 and protects the house advantage over the long-run. It is important for players to understand dealer rules to be able to make the best strategic moves for optimal success. The common rule is that the dealer must hit when the total of their hand is 16 or less. The dealer must continue to hit until their hand totals at least 17, or until he busts.

  1. Dealer hits up to 16 – the dealer will draw cards if the total value is less than 16
  2. Dealer must stand on 17 or more – the dealer will stop drawing cards when the value is 17 or more.
  3. Dealer hits on soft 17 – this rule means the dealer must hit if their hand totals 17 and includes an ace.

Given that there are many variants of online blackjack, you will find that there are different rules that apply to the actions the dealer can take. In some games, when the dealer has a soft 17, that is, a hand totaling 17 which includes an ace, they must hit again. In most variants, the dealer will stand on a soft 17. This is the more common rule as it slightly raises the house edge. The rules regarding the dealer standing or hitting on a soft 17 impacts the best action for the player to take.

Depending on the game variant, there are a variety of side bets that you can place when playing blackjack. Such optional bets can add an extra element of fun and entertainment to traditional gameplay. Although, it is worth noting that payout rates for side bets are generally lower than regular bets. Whilst some of the side bets boast the potential for big payouts, they are riskier bets and are unlikely to increase your profits in the long run. As such, they are best avoided. That being said, if you want to add a little extra excitement to your blackjack game, there are plenty of side bet options to try your chances on. Below you can find out some of the most common blackjack side bets.

The 21+3 side bet is one of the most commonly found in online blackjack games. Payouts are made based on the player’s first 2 cards and the dealer’s up card. The player wins if the 3 cards contain three of a kind, or a flush, straight, or straight flush. Payouts range from 5:1 for a flush up to 100:1 for suited trips. Based on a six-deck blackjack game, the expected RTP of the 21+3 side bet is 96.77%.

The Perfect Pairs side bet is available in many blackjack variants and is a simple, yet popular bet. To win the bet, the player must be dealt a pair. There are different payouts for different types of pairs. A payout of 5:1 is made for a pair of mixed color and suits. Same color and mixed suits payout 10:1. A pair with the same color and suit pays 30:1. This bet has an RTP of 94.21%.

The next table shows the probabilities of the player busting when hitting. You can never bust with your initial two cards as the highest possible hand total is 21. Of course, if you have a hand total of 21 and you opt for another card to be dealt, then there is a 100% probability of your hand busting. Whereas a hand value of 11 or less cannot bust by being dealt another card. In essence, the higher the player’s total hand value, the higher the odds of busting.

After players have completed their turn, it is the dealer’s turn to play. Once they have completed their turn, all hands are compared to the dealer’s. If the player beats the dealer with a higher hand total, a payout of 1:1 is awarded. So, if you bet $10, you will win another $10 and the $10 stake is also returned. If you hit a blackjack, that is, an ace with a 10-value card, the payout is 3:2. So if you bet $10, you win another $15. If the player and dealer hands are equal in value, the result is a push and the original bet is returned to the player.

When you take into consideration the difference between the probability and the payouts, you find the house edge. Casino games are calculated in a way so that the house always has a small advantage, hence the expression, the house always wins. Another way of expressing this is return to player, or RTP. Whilst the house edge expresses the percentage of all bets on a game that in the long run are kept by the casino, the RTP expresses the percentage of money bet that is paid back to players. Blackjack is one of the casino games with the lowest house edge, providing favorable odds for players. You can see how the house edge of blackjack compares to other casino games below.

  1. Blackjack pays 2 to 1: -2.27%
  2. Single deck: -0.48%
  3. Hitting split aces: -0.19%
  4. Player may re-split aces: -0.08%
  5. Dealer hits on soft 17: +0.22%
  6. Blackjack pays 6 to 5: +1.39%
  7. Blackjack pays 1 to 1: +2.27%

As you can see, blackjack games come from a variety of different software providers, who bring their own style of graphics, interface and side bet features. Most casino fans usually pick a provider they like and stick to their titles, but it is always a good idea to keep your options open and register at a site offering a rich variety.

Blackjack is one of the few casino games where strategy can make a difference.

In the following sections, you will learn all the tips, strategies and systems that you can use to win at blackjack.

By playing using a basic strategy chart, you can secure the lowest house edge. It takes away any need to guess what decisions to make and ultimately provides you with the best move mathematically to play your hand. Yet there will still be a house edge when you follow the basic strategy. As such, if you want to maximize your chances of winning in the long-term, you need to combine it with other techniques.

By combining basic blackjack strategy with card counting, you can reduce the house edge as low as possible. Card counting is a system that gives you an overview of the balance of high and low cards left in the shoe. When there are more high cards left, the situation is more favorable for the player. As such, you can adjust your bet size according to the ratio of high to low cards to optimize your chances of profits. Card counting does not require you to keep track of each and every card that is dealt. Instead, a positive, negative or neutral value is assigned to the cards, and you keep a running count as they are dealt. The most basic method of card counting is the hi-lo system. Yet there are other optimized systems which have been developed. You can see some of the best-known card counting systems below.

The basic principle of card counting is to keep a running count of cards as they are dealt. If the running count increases, the advantage shifts to the player. This is because the shoe will have a higher concentration of 10s or aces. This, in turn, means that more blackjacks will be dealt and that there will be more chance of the dealer busting. On the other hand, when the running count is negative, the casino’s advantage increases. This is because more low valued cards mean less chance of blackjacks being dealt and that it is less likely for the dealer to bust. When using card counting systems, players also need to calculate a true count, which adjusts the positive/negative running total according to the number of decks remaining.

Whilst card counting can boost a players’ chance of winning in the long run, it is worth keeping in mind that cards are shuffled after every round in most online blackjack variants. As such, card counting will not work in such games. However, you can apply the strategy when playing live blackjack. And, of course, you could try using card counting when playing in a brick and mortar casino. Contrary to popular belief, it is not forbidden to count cards in a casino. However, many casinos frown upon the practice, and will often ban players they suspect to be using such systems to try and gain an advantage over the house.

Blackjack betting systems are another strategy that can be used when playing the card game. Such systems relate to how you make your wagers, changing the bet amount under certain circumstances. There are two main types of systems, positive progressions and negative progressions. With positive progressions, you increase your bet amount after wins. Negative progressions, on the other hand, involve raising your bet to compensate for losses. There are many different betting systems based on these principles. Here you can find some of the most commonly used blackjack betting systems.

  • Martingale: A popular and well-known betting strategy. The Martingale system works by doubling your bet following a loss. If you bet $10 and lose, your next bet would be $20. You continue to double your bet with each loss until you win a round, at which point you return to your original bet size. This system means that you recoup all losses and make a small profit when you win a game. This is, however, a risky strategy as bet sizes can quickly increase following a run of losses, and you may reach the maximum bet limit or exceed your bankroll before you are able to win back any losses.
  • Fibonacci: This system is based on the Fibonacci Sequence, whereby the next number in the sequence is equal to the sum of the previous two numbers. The sequence is as follows; 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on. To use the negative progression system to play blackjack, with each losing bet, you will increase your original bet multiplied by the next number in the sequence. When you win a bet, you would move down two numbers in the sequence.
  • Oscar’s Grind:  Also known as Hoyle’s Press, this betting system involves increasing bets by a factor of one for every win. This continues until any losses have been recuperated and you win a profit matching the base bet. You then start the cycle again, with the aim of winning one unit of profit per cycle.

You will find that most blackjack games are available in play money mode. To get you started, you can try out the free game above and play for as long as you like without spending your own cash. Most online casinos offer blackjack online for free – in demo mode, of course. So, if you fancy trying your hand either at a classic blackjack game or if you want to try out an innovative variant, you will find plenty of options available to you at the best casino sites. You can try out different demo games to find the one that suits your preferences and style of play. Playing games in demo mode will prepare you fully to play confidently with real money.

There are some basic rules you can follow to ensure that you have the best chances of winning at blackjack. Unlike simple games of chance, you can use your skills to improve your odds. For your convenience, we have made a list of blackjack tips that can help you to up your game. You won’t become a pro, but you also won’t need a blackjack trainer just yet!

Playing blackjack with bonuses is at the heart of advantage play. Casino bonuses boost your bankroll, giving you more playing time and as such, more chances to win. Blackjack bonuses come in all shapes and sizes, and the amount of the bonus is not the only thing to consider when identifying the best deals. Just as important is finding a bonus with favorable conditions for the game. All bonuses come with a wagering requirement, which indicates how many times you need to turn over the bonus before you can withdraw any winnings you make with it. The lower the wagering requirement, the better the offer.

You also need to take into consideration the blackjack wagering contribution. As the game has such a low house edge, casino operators compensate for this by only counting a certain percentage of any wagers made on the game towards clearing the wagering requirements. The higher the blackjack weighting, the better the deal.

Playing blackjack on mobile phones and tablets has never been more popular. It is a super convenient way to play. You do not have to tie yourself to a desktop pc to play, you can simply grab your mobile and indulge in real money game play anytime and anywhere you fancy. The best casino apps feature a rich selection of popular blackjack games, which have been optimized for mobile play. You will find that such apps are compatible with most iOS and Android devices, making them widely accessible to many players.

The game of blackjack is steeped in history. However, its origins are not clear-cut. In fact, it seems that blackjack has evolved from other card games over the years to become the what we know today. The commonly accepted theory is that it is derived from the French game of Vingt-et-Un (21), which was popular during the reign of King Louis XV and was regularly played at the Royal Court. Yet there are other games that can be seen as precursors to Vingt-et-Un, including the Italian Sette e Mezzo (seven and a half) and the Spanish game Trente-un (31), which had similar objectives.

French colonists later took the game to America, where it became known as 21. Since then, the game’s popularity boomed. Mathematicians and statisticians produced strategies for optimum play and card counting were introduced in the 1950s. This, in turn, increased the popularity of the game as players flocked to casinos to put the theories into practice to try and beat the house. The popularity of blackjack continues to thrive to this day, as the internet makes the game accessible to many more players worldwide. In the following timeline, you can get a glimpse of the rich history of blackjack.

January, 2019

The French card game called Vingt-et-Un (21) is played in the Royal court during the reign of Louis XV. The aim of the game is to beat the dealer without exceeding 21. This is considered by many as the most likely origin of the modern game of blackjack.

Vingt-et-Un is brought to America with French colonists, and its name changes to 21. Changes to the basic rules see the dealer start to follow mandatory blackjack rules rather than making his own decisions on how to play blackjack.

Casinos are legalized in Las Vegas and 21 becomes a hit house-banked game. Game standards and controls are introduced by the Nevada Gaming Commission to ensure set blackjack rules are applied to the game.

To make 21 more appealing to players, some casinos introduce bonus payouts of 10:1 for getting 21 with an ace of spades and a black jack (spades or clubs). This leads to the game being known as blackjack rather than 21. The 10:1 payout is soon removed, but the name remains.

If you stop to think about the best land-based casinos that can be found around the world, Las Vegas no doubt springs to mind. Sin City is jam-packed full of prestigious casinos where you can play the game of 21 in the most impressive of surroundings. Yet aside from Vegas, there are top casinos that feature blackjack to be found all over the world. We have done the research to find the best real casinos for playing blackjack. To pick the crème de la crème, we have taken into account the number of tables and their betting limits, as well as the location of the casino. Whether you want to play in the USA, Europe or Asia, we have got you covered. Check out details of the top blackjack casinos in the table below.

There are certain rules of etiquette that blackjack players adhere to at real casinos. As such, it is a good idea to brush up on the basics to avoid any embarrassment at the table. For starters, it is customary to ask whether you can join the game if there are already other players at the table. Whilst there is little doubt that you will be invited to join, it is still polite to ask. As for changing your money into chips, you can buy chips from the casino cashier or directly from the dealer. If you buy them from the dealer, be sure to wait until the end of the current round, then place your money on the table, rather than into the dealer’s hands. Make sure you do not place the cash on the betting circle either to avoid any confusion. You can play blackjack only if you are seated at the table. When you are ready to play, place your chips on the betting circle in front on you. Once cards have been dealt, do not move or touch the chips that you have bet. And a final note on etiquette, it is a common custom to tip the dealer at the end of your game, regardless of whether you win or lose.

When it is your turn to play your hand, you can use hand signals to state your decision as well as, or instead of actually saying the words. It can be noisy in real casinos, so using hand signals is a good way to emphasize your decision. It also has the benefit of being seen by the casino security cameras. So, if there is ever any dispute or mistake made by the dealer, your actions will be clear to see on a video replay. There are four basic blackjack hand signals that you can use when play in a real casino.

  • Hit: Tap table once or twice with finger or point at your cards
  • Stand: Wave your hand from left to right over your cards without moving your arm
  • Double Down: Place an extra wager next to your original bet then hold up one finger
  • Split: Add a second bet outside the betting circle beside the first wager, then hold up two fingers.

When it comes to the legality of playing casino games, it varies according to different jurisdictions. Some countries, such as the UK have a fully licensed and regulated gambling industry, where it is legal to play blackjack both in land-based and internet casinos. Whereas other countries place restrictions on some forms of gambling. Always check the legal situation of playing blackjack where you are based to be sure the game is permitted where you are. In the table below, you can see an overview of where it is legal to play blackjack in different countries around the world.

Blackjack is one of the most popular games in the world. So, naturally, there are many references to the game in popular culture, especially when it comes to movies. There are countless films which are based on blackjack, with both fictional and real-life stories providing the storyline. Take for instance 21, which is based on the infamous MIT blackjack team. There are also plenty of films which feature some unforgettable scenes. A great example here is Rain Man, when Dustin Hoffman’s autistic character Raymond counts cards, enabling the brother duo to clean up at the casino. Below, you can see at a glance some of the best blackjack movies.

If you are wondering if watching movies will improve your game, then it depends on the type of film you watch. Some films are made purely for entertainment, and whilst they feature the game, they provide little to help you improve your chances of winning. Yet there are also plenty of blackjack films that provide an insight into card counting and other such strategies that can help build your understanding of how to play blackjack with an advantage.

As with movies, you will find many blackjack books available. Yet whilst there are fictional stories that incorporate blackjack within the storyline, the bulk of blackjack books are fact-based, focusing on mathematical strategies, systems, and theory. There are books that cater to players of every skill level, from beginners to the most experienced professionals.
