How to Play Blackjack
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.

Basic Blackjack Rules
In blackjack, you play against the dealer. When you play online, you alone will go head to head with the dealer. Whereas if you play blackjack in a land-based casino, up to 7 players can join the table and simultaneously play against the house. Casino blackjack is commonly played with six to eight standard decks of playing cards. To play the game, you place a bet, which must fall within the limits specified on the table. Two cards will then be dealt to each player and two to the dealer. Players then have the choice to receive extra cards, or to stick with the hand dealt. Once each player has completed their turn, play passes to the dealer, who will draw cards according to the game’s rules. For a player to win, their hand must have a higher total value than the dealer, without exceeding 21. If the dealer busts, the player also wins. If there is a tie, the result is a push, and the player’s bet is returned. The best hand in the game combines an ace with a 10, Jack, Queen or King totalling 21. This is known as a blackjack or natural.
Blackjack Basic Тerms:
- Buy-In – To exchange your cash for chips to be used at the blackjack table;
- Blackjack – The best hand in the game, made up of an ace and a 10-value card (i.e. 10, J, Q, K);
- Bust – When the total value of a hand exceeds 21;
- Push – A tie; the player and dealer have hands with the same total;
- Hole Card – Dealt to the dealer face down, it isn’t revealed until the players’ turn is over.
Rule Variations
You can play many games online that follow standard blackjack rules. Yet you can also find numerous online blackjack game variants. Such games feature small variations to basic rules, creating a twist on classic gameplay for a different kind of playing experience. The rule variations can impact the house edge, making a particular game ore or less favorable for players. Further differences between blackjack variants can be found in the number of decks the game is played with. Shuffling rules can also differ between variants.
Blackjack rule variations:
- Hit after split aces – The common rule is that only one card will be dealt to each hand when you split aces and you cannot split, double or take another hit on a hand.
- Double after split – Standard game rules allow you to double down on the new two-card hands.
Table Layout
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.
Player’s Turn: Options & Decisions
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.
Blackjack Dealer Rules
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.
- Dealer hits up to 16 – the dealer will draw cards if the total value is less than 16
- Dealer must stand on 17 or more – the dealer will stop drawing cards when the value is 17 or more.
- 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.
Side Bets
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.
21+3

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%.
Perfect Pairs

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.

Payouts
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.
House Edge/RTP
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.

Blackjack Basic Strategy
When you play blackjack, you make a series of decisions regarding how to play your hand. Yet how do you know which is the best action to take? Blackjack basic strategy is a set of rules which tell you the best action to take based on your two-card hand and the dealer’s up card. Given the numerous possible hand combinations that you can be faced with, you can use a simple blackjack strategy chart to be sure you make the optimal move. A blackjack strategy chart is based on mathematical principles that maximize your chances of winning. Below, you can see a blackjack basic strategy chart. You will see that it contains every possible combination for a player’s starting hand and the dealer’s up card. Follow the chart and you can be certain that you take the best action to boost your chances of success – however, keep in mind that the different variations of blackjack rules can lead to some minor differences.

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.
Blackjack Card Counting
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
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.
Shuffle Tracking
Shuffle tracking is a technique used in conjunction with card counting to try and gain an advantage. It is an advanced technique that involves the player tracking certain cards or sequences of cards through a series of shuffles. To use shuffle tracking, the player keeps track of how cards are put into the discard tray and shuffled, to try and help predict which cards will be dealt in the next shuffle. By keeping tabs on certain clusters of high or low cards, the player can then adjust their bets when more advantageous cards are likely to be dealt.
It is a hard skill to master, yet it can squeeze the house edge even lower when done right. When playing blackjack online, cards are automatically shuffled, and it renders shuffle tracking ineffective. Although, in a similar way to card counting, you can put the technique into use when playing live blackjack. However, it requires vigorous training. If you want to learn how to play blackjack with shuffle tracking – just put the necessary time into training, and consider the free blackjack games available online to get a better grip of the speed involved.
Play Online Blackjack for Free
For all the different blackjack strategies and systems to help you win, the most important factor is to understand the rules of the game.

How to Find the Best Blackjack Bonus
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.

The higher the blackjack weighting, the better the deal.

Live Dealer Blackjack Online
Whilst some people love the convenience of playing blackjack online, there are others that miss the real casino atmosphere of playing in a brick and mortar casino.

History of Blackjack
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.
Blackjack History Timeline
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.
Legalized and house-banked games began to appear in New Orleans. 21 begins to gain increased popularity across the whole of Northern America.
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.
Blackjack at Land-Based Casinos
If you visit any big casino, you will find that they offer multiple blackjack tables. There are different table limits, ensuring that all types of players are catered for, from beginners and casual players to experienced high rollers. Playing blackjack at a real casino has its perks.

You can encourage others as they play and enjoy the praise and congratulations that will come your way if you have a winning streak.

Be sure to brush up on table etiquette and the signals and actions you can use to play your hand before you venture to the casino.

Table Etiquette
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.
Signals When Playing at Real-Life Casino
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.
Hand Signals When Playing Real-Life Blackjack:
- 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.
Real Casino Tips
There are a few blackjack tips that can help you up your game when playing in a real casino. Unlike online blackjack, the cards are not shuffled after every round. As such, this gives you the opportunity to use card counting to your advantage. You should keep in mind, however, that although not strictly forbidden, card counting is frowned upon by casinos. As such, if you plan to use the system to your advantage, be sure to do it as discretely as possible. Another useful tip that could help you gain an advantage is to look for dealer tells when they peak at the hole card. You may pick up on subtle gestures as to what the hole card is, which you can then exploit for your benefit.
Where Is Blackjack Legal?
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.
