What Is the Blackjack Basic Strategy?

Knowing how to manage your money is as important in blackjack as it is in all gambling games. A correct 'bankroll management' is essential when you play — regardless of the blackjack strategies you apply to your games.

Knowing how to bet (and how much) and how to select the right game when you play online blackjack for real money is extremely important.

Once you have those basics covered, you can move into the basic blackjack strategy and learn how you are supposed to invest your money once the dealer gives you the initial two cards.

As soon as the cards reach you and the dealer opens one of their cards, you have to make your first choice. In a game of blackjack, that means you need to pick one of these options:

Deck
  • Stand
  • Hit
  • Double
  • Split
  • Surrender

Do you know why the basic blackjack strategy is also considered to be the best way to discover how to win at blackjack? Because it uses basic logic.

Would you hit if your first two cards gave you 20 points? Of course not.

Would you stand if your starting hand was worth five points? Not a chance.

While these choices are very simple on hands like the ones I use in my example, things get (a lot) more complicated with different cards on the table.

Let me give you a few examples.

  • How do you play soft 17 in blackjack?
  • When do you hit on a 16?
  • What to do with 15 in blackjack?

This is where the basic blackjack strategy comes in to help you get the best chances to win.

This collection of tips shows you the optimal play for every blackjack hands, calculating your winning odds in combination with the dealer's open card.

The basic strategy to win at blackjack has nothing to do with concepts like card counting or any of those tricks some 'clever' players adopt to beat the house.

This is a simple-to-use guideline that shows you exactly how you are supposed to play every possible hand of blackjack. Use it to know when it is recommended to hit, to stand, or to do something else.

A Conservative Blackjack Strategy

Don't play high-stakes games unless you feel ready for them and you have enough money to spend on online games.

If you are reading this blackjack strategy guide and you are a beginner, you should be afraid of high-stakes games.

When you spend too much money on your games, you risk getting the opposite of what you want. You play to have fun and to find out how to get more chances to win at blackjack - and you end broke and frustrated.

The best way to play blackjack is to start with what I call a conservative approach. Because finding the right way top handle betting in blackjack is key to long-term fun.

Like many blackjack strategies suggest, you should increase the stakes only when things go well and any potential losses are compensated by the money you have already won, not the one you might win if you get lucky.

In other words, raise your bet every time you win.

Many players believe wins and losses come in streaks. They think you might lose five or six times in a row — but when you win…you are not going to do it just once.

Obviously, that's not true.

Blackjack is a gambling game and there are no patterns for you to exploit or streaks that you can use to win more money every time you play.

There are, however, smart betting strategies like the basic blackjack strategy that can help you increase the chances of a victory.

With that in mind, a conservative blackjack strategy works like this:

  • Start from the lowest bet (e.g. $1)
  • Increase your bet by 1 unit only after you win
  • Go back to the original bet after you lose
Blackjack betting strategy

When you use this blackjack strategy, you need to go back to the original bet as soon as you lose one hand. This is the best way to be in control of your money and end a gaming session in the black.

All you need to do is to make the right choices (use the basic strategy) and raise your stakes little by little - but only when you win.

An Aggressive Approach to Blackjack: the Martingale Strategy

The Martingale betting strategy sits at the opposite side of the spectrum. This is the perfect blackjack strategy for those players who:

  • Play blackjack to win a lot of money
  • Can afford to lose a lot of money
  • Don't fear the swing of big losses

In other words, this is the perfect blackjack strategy for big spenders but isn't one that you should try if you are still a beginner who is looking for ways to learn how to play blackjack.

The Martingale blackjack strategy is expensive. This is a blackjack system that will help you win often - but only when I have a lot of money to invest on your games.

If you can't spend at least $500 on your games - the Martingale is not the best blackjack strategy for you.

But if you do — continue reading to discover how to use this betting strategy to increase your chances to win.

In short:

The Martingale strategy is the exact opposite of the conservative approach to betting in blackjack we have just seen.

When you follow this strategy, you need to double your bet every time you lose. Which, in case of a losing streak, can become very expensive very quickly.

The rationale of this audacious blackjack betting strategy is that you will need only one win to go back to square one and recoup all your losses in one hand.

The caveat is: your bankroll needs to be deep enough for you to play and play until that one win comes.

Again, this isn't a betting strategy for beginners. If you decide to try it, make sure your bankroll covers at least 10 consecutive losses from the hand #1.

1-3-2-6 Blackjack Betting System

The 1-3-2-6 blackjack betting strategy is not as exciting as the Martingale strategy, and that's a good thing. This betting strategy doesn't require a huge bankroll and is a lot more suitable for players looking for a way to have better chances to win at blackjack without investing a fortune in the game.

The numbers in the strategy's name indicate the way you should bet after you win a hand of blackjack.

You first winning is the trigger that starts the sequence while your first losing hand is the one that ends everything.

This blackjack betting strategy is built to get the most value out of winning streaks. If you are lucky enough to use it at the beginning of a four-hand winning streak, you are in for a treat.

How to Win More Often at Blackjack: A Few Important Tips

We all want to win at blackjack every time we play, but we also know that's impossible.

What is possible, however, is to maximise your chances to win and get better winning odds when you play blackjack online. All it takes a few simple tips.

Blackjack

Follow them carefully, as these blackjack tips are as important as the best blackjack betting strategy.

  • Don't spend money on the 'insurance'. The insurance bet is a money-draining option created to confuse beginners. All the best blackjack strategies fail to mention is for one simple reason: no real blackjack player will ever spend their money on it.
  • Think about the house edge. Like we said when we went through some of the game's best betting strategies, you can't expect to win at blackjack every time you play.

    Like all other casino games, the house edge is what makes sure that the casino has an advantage over the players in the long run. With that in mind, the next of our blackjack tips is one that can make a great difference for you.

  • Set a budget and abide to that. Experienced blackjack players know that you need to set a losing and a winning limit before the first hand is dealt.

    Stop playing as soon as you hit one of them. If you lose and hit your lower limit, take a break and end your session.

    If you win and you hit your highest limit, collects your winnings and leave the table. You can continue to play if you want, but you'll need to set a new bankroll and establish new limits first.

  • Don't miss the rules sheet. Trust me, there are more blackjack variations that you will ever play. All of them are based on the same core gameplay — but adopt rules that could break you if you aren't ready for them

    One of the best parts of playing online is that the rules are always available at the table. If you are not sure you know everything about the game you want to play, click on the 'info' icon and read the rules.

  • Choose 3:2 over 6:5 payout. Different casinos have different payout policies - and not all of them are great for you.

    Make sure you read the payout table before you begin to play a hand of real money blackjack and always choose the games with the 'regular' 3:2 payout. These are a much smarter choice compared to the 6:5 payout blackjack games you find at some online casino sites.

HistoryHow To PlayRulesOddsStrategyPro’s Perspective

Whether online or land-based Blackjack is one of the most popular card games at casinos, whether online or land-based. The game is sometimes referred to as 21, as players will try to get a hand total that is equal to 21. The game is not a competitive game in that players do not compete against each other. It is only played between the player and the dealer at the blackjack table. When the showdown occurs, players will not compare their blackjack hands together, but will instead compare their hands with the hand of the dealer.

There are many versions of the game, but they all have the same concept and target, which is reaching a hand total of twenty-one. The game begins with each player being dealt 2 cards. Players will then go through a series of decisions that depend on the hand total and the cards forming the hand. These decisions include “Hitting”, “Standing”, “Splitting” and “Doubling Down.”

When players get an ace and a jack or any other ten-value card, they will instantly win, and it is called Blackjack. Players will be rewarded more than the usual winning hand ( for Blackjack which is usually 3 to 2) while regular winning hands would pay even money (one to one). There is also a selection of side bets that players can place, depending on the blackjack version. The typical side bet in most blackjack games is an Insurance bet.

Blackjack History

The origin of Blackjack, like many other casino games, is still debatable. Nonetheless, most people agree the game of Blackjack originated in France in its land-based casinos in the 1700s. The game was called Vingt-et-Un. Vingt-et-Un is a French word that translates to twenty-one (21) in English, which is how players still use to refer to blackjack to this day. Some researchers believe that the game was derived from other card games that were popular in France at the time. These French games were French Ferme & Chemin de Fer, which had many similar rules and procedures.

Though Blackjack is thought to originate in France, the game was first referenced in a novel written in the 1600s by the Spanish author Miguel de Cervantes. In the book, he describes two characters playing a card game that was named Veintiuno (Vingt-et-Un), and the rules of the game were pretty similar if not the exact rules of Blackjack.

Players dealt with cards, and the purpose was to get a hand total that is as close to twenty-one as possible without busting. In this game, the Aces counted as either 1 point or 11, just the like modern-day version of Blackjack. The book was written in the early 17th century, which adds credibility to the theory that the game actually originated in Spain.

Later on, the game of Blackjack traveled throughout Europe, however, leaving the most prominent tracks in Spain and France. Eventually, the game was introduced to the US.

Among the different versions of Blackjack, Vingt-et-Un (21) was the one that spread the most. It started to appear gradually in North America among the French colonists. However, the rules of Vingt-et-Un at that time differed slightly from modern-day Blackjack. For example, the dealer was the only person permitted to double down, and there were wagering rounds between each dealt card.

The game became very popular in Nevada as it was the first state to legalize gambling in 1931.

At that time, the game was still named 21. For the casinos to attract players and encourage them to play the game, they offered the chance to place a special bet. This bet would pay players 10: 1 if they got a blackjack with a Jack of Clubs or Spades, along with an Ace of Spades. This is where the name Blackjack originated.

How to Play Blackjack

Like any casino card game, players will start by placing a bet. This is the final bet and players will not be able to reduce it or add to it (unless the game allows for doubling down) during gameplay. Once players place their respective bets, they will get two cards facing up while the dealer will give himself two cards though one is facing down, and the other is facing up. In some versions, the two cards of the dealer will also be facing up, for example in Blackjack Double Xposure.

Some games allow players to place bets on more than one blackjack hand; they are called multi-hand blackjack games. In these games, players will place a separate bet for each hand, and each hand is played separately. Although it is very rewarding, and it enables players to recover from the loss of one of the hands by winning the rest, it can also be devastating if the dealer gets a good hand or a blackjack.

Players will calculate their hand total, and make a decision to: either “Hit” or “Stand.” If they “Hit”, it means that they are not satisfied with their hand total and that they want more cards. They can keep hitting until they “Stand” which means that they are happy with the hand total or until they “Bust.” Busting means going over 21; if players bust, the hand is an immediate loss.

Once players stand, the dealer will show his hole card, which is the card that was facing down. He will then start “Hitting” which means to draw more cards until he reaches or passes 17. Some games obligate the dealer to stand on all 17s, and some require the dealer to stop at only Hard 17s. After the dealer stands, a comparison between the hand of the dealer and the hand of the player will take place. The hand that is closest to 21 is the winning hand. If the two hands have the same value, it’s a tie, which really depends on the rules of each version. When there is a tie, it is called a “Push”; some versions would consider it a tie and give players back their bets while other games consider a Push to be in the favor of the dealer.

There are other decisions that players will need to make during the gameplay. For example, players can “Split” If they get identical cards to form two hands. The two hands will have the same value of the original bet. Some versions would enable players to split more than once to form 4 different Blackjack hands. Also, some versions would allow players to split, unlike ten-value cards like a Ten and a Jack, or a Jack and a Queen. Players can split aces in some versions, but they will only be able to hit once and if they get a ten-value card, they will be paid even money as it is considered an average win and not a Blackjack.

Blackjack Rules

The rules of blackjack depend on which version is being played. Players are advised to check the rules of the specific blackjack version they are playing before engaging in the game. Although there are common rules like 21, busting, the dealing procedure and the card value, there are other rules that differ.

Card Values:

The card values are equal to the face value of each card, while Jacks, Queen, and Kings have a value of ten. Aces can be counted as either 11 or 1, depending on the blackjack hand. If it forms a total while being counted as 11, it is called soft, and if it creates a total while being counted as 1, it is called hard. For example, a hand that consists of an Ace and a five is a soft sixteen and a hard six.

Splitting Rules:

Splitting is allowed in every blackjack game, but some games will not allow splitting Aces and some games will only allow players to split 1 time. Players who split aces will only be allowed to hit once and get one more card. Players can split unlike ten-value cards depending on the rules of each game; some allow it while some require players to get identical ten-value cards so they can split. Splitting means that players will place a new wager which on the new hand, which is equal to the original wager was placed on the Blackjack hand; with four hands players can quadruple their original wager.

Blackjack Strat

Double Down Rules:

Players will be permitted to double down after they get their first two cards. Some games enable players to double down at any value and others only allow them to double down if they get a hand total that is equal to 9, 10 or 11. Players will only be able to get one more card after they double, they will have to take that card, because it is not optional.

Surrender Rules:

Blackjack Strat

Some games will give players the chance to surrender their blackjack hands; it is the equivalent of folding in poker. Players can make that decision after they are dealt the initial two cards. If they surrender, they will forfeit the hand, and they will lose half of their bet. Sometimes it is better to lose half than to lose the entire bet.

Insurance Rules:

Insurance is a side bet that players can place if the dealer’s card that is facing up is an Ace or a ten-value card. Players will win that bet if the hand has a blackjack. The dealer will peek and see his card once players place that wager and pay it out if it is a blackjack.

If players do not place insurance, and the dealer gets a blackjack, all the wagers, except insurance will bust. If the player has a blackjack as well, it is considered a push. Some variations will give players their bets back, while others consider a push to be in the favor of the house.

Blackjack Odds

For you to fully understand the game, it is essential to comprehend and master the odds of the game and learn about the advantage of the house. It is critical to know how the house gets its edge.

The house has a distinct advantage over the players because players have to draw in blackjack first. If the player busts, the dealer will automatically win regardless of their hand. This is the main advantage the house has, and if everything else is equal, the house edge in a standard game of blackjack would be equal to 8 percent. The player and the dealer have a 28 percent probability of going over 21. Twenty-eight multiplied by twenty-eight means that 8 percent of the time the two hands will go over 21, and since the player will draw first, the dealer will win if and when they both bust.

Odds of Busting Based on Dealer’s First Card Drawn

Of course, the odds are not equal among all variations. Some offer players great advantages and, to balance these benefits; the casino increases its advantage or edge. Because of this, it is essential for players to know everything about the game before playing.

For example, the number of decks in play has a tremendous effect. Some games draw cards from a single deck, which can affect the odds significantly while other games draw the cards from six different decks of cards. If a game uses one deck of cards, the house will change other rules to increase its odds and reduce the odds for players. This is because when a player gets an Ace, it means there are 3 Aces left which decreases the chances for the dealer in getting one of these aces. On the other hand, if the game uses 6 decks, it means that there are 23 Aces remaining in the deck.

Blackjack Strategy

The odds on a player’s hand will change every step of the way. For example, if players get two cards, and they hit, the hand total will increase, and the chance of busting will increase, and so forth.

Odds of Busting based on Player’s First Card Drawn


Since Blackjack is one of the games with a reputation of counting cards, a lot of researchers and gamblers have studied the game and the odds so they can increase their chances of winning. You might have seen that in the movie “21” where MIT students developed a way to beat the house. For them to do that, they had to make up a counting system that would increase their advantage. This is why there are published studies that show the percentage of busting and getting a blackjack depending on the first 2 cards, the hand total of the player, and the facing up card of the dealer. You can find more about these strategies and percentages in the Strategy section.

Blackjack Strategy

Before discussing strategy, let us firstly go through some numbers that can be quite helpful. For starters, we will discuss the bust probabilities for each hand total. This will enable players to optimize their game to the fullest by knowing the percentage of busting if they ask for one more card.

– If players get a hand total of 11 or below, the percentage is equal to zero.
– If players get a hand total of 12 or below, the percentage is equal to 31.
– If players get a hand total of 13 or below, the percentage is equal to 39.
– If players get a hand total of 14 or below, the percentage is equal to 56.
– If players get a hand total of 15 or below, the percentage is equal to 58.
– If players get a hand total of 16 or below, the percentage is equal to 62.
– If players get a hand total of 17 or below, the percentage is equal to 69.
– If players get a hand total of 18 or below, the percentage is equal to 77.
– If players get a hand total of 19 or below, the percentage is equal to 85.
– If players get a hand total of 20 or below, the percentage is equal to 92.

From these numbers, players can figure out when they should stand and when they should hit. Players who get a hand total of between 2 and sixteen should generally hit and get another card. If they get a hand total that is more than 17, they should typically stand.

Of course, players will have to take the showing card of the dealer into consideration. The next set of numbers shows the dealer’s chance of busting according to the facing up card.

– Ace (11.65%)
– 10/Face Card (21.43%)
– 9 (23.34%)
– 8 (23.6%)
– 7 (25.9%)
– 6 (42.08%)
– 5 (42.89%)
– 4 (40.28%)
– 3 (37.56%)
– 2 (35.30%)

Taking these numbers into consideration, as well as the previous ones, will help players decide whether they should hit or stand.

Besides hitting and standing, players should also know when to split and when not to split:

– When players get Aces or 8 cards, they should always split. There is a big chance to get a hand total that is closer to twenty-one when you hit on these two cards.
– Players should never split 10, 4, or 5 cards, regardless of the upcard of the dealer. Splitting in these scenarios will put you in danger of busting.
– Players should split 7, 3, and 2 cards if the dealer is showing a card between a 2 and a 7. If the value of his card is 8 or over, you should hit instead of splitting.
– Players should split 6 cards if the dealer is showing a card that has a value between 2 and 6. If the value of his card is equal to 7 or over, you should hit instead of splitting.

With John Grochowski

Single Deck Blackjack Strategy

Not all blackjack games are created equal. Beyond the basics, there is a mix-and-match set of rules, and each casino chooses the conditions for its own game variations. Some rules are favorable to players while others give the casino an extra edge.
Let’s look at some of the more common options.

Number of Card Decks

Fewer decks are better for players. That’s because more blackjacks are dealt with fewer decks. That’s true for both players and dealers, but players are paid a premium on blackjacks and dealers aren’t.

In a single-deck game, if your first card is an Ace, 16 of the other 51 cards, or 31.4 percent, are 10-value cards that complete a blackjack. In a six-deck game, a first-card Ace leaves 64 of the other 311 cards, or 30.9 percent, as 10 values. There is a similar effect when the first card is a 10-value. Regardless of whether an Ace or a 10 comes first, there is a greater chance of blackjack with fewer decks.

However, not all single-deck games are better than all multi-deck games. You need to consider other rules in effect, including those listed below.

Blackjack Rules

Blackjack Betting Strategy

The basic blackjack rule is that the dealer hits on 16 or less and stands on 17 or more. However, many casinos have the dealer hit soft 17, where an Ace is being counted as 11. Soft 17s such as Ace-6, Ace-2-4, Ace-3-3, and others can’t be busted with a one-card hit because the Ace can be counted as 1 instead.

It’s better for players if the dealer stands on all 17s. Hitting soft 17 gives the dealer a chance to improve to hands that could beat player 17s, 18s, 19s or 20s, and even push player 21s.

For most of blackjack’s history, two-card 21s have paid 3-2 so that a $10 bet brings $15 in winnings. Some casinos nowadays only pay on 6-5 on blackjacks, so a $10 bet only wins $12. This is one of the most important rules in blackjack. If blackjacks only pays 6-5, it adds 1.4 percent to the house edge – an amount greater than the entire house edge in many games that pay 6-5.

Variations of Double Down

As a player, you want to see games where the player may double down on any first two cards, including after the player has split pairs. If you split a pair of 8s and receive a 3 on one for a two-card total of 11, you want the option of doubling down. It increases the house edge if the casino does not allow doubling down after splits. Similarly, some casinos do not allow doubling down on soft hands and some restrict doubling to two-card totals of hard 10 or 11.

Fewer restrictions are better for smart players who know how to use them. Have your web browser search for basic strategy charts. They’ll tell you the proper times to double down along with the best plays for each possible hand.
