Blackjack Games Overview

Blackjack games overview

Blackjack's exact beginnings are uncertain, but it's widely believed to have emerged in French casinos around 1700 as "Vingt-et-Un," meaning "twenty-one"[1]. This game probably evolved from the then-popular Chemin de Fer, played at King Louis XV's royal court. A similar variation is the Russian game Ochko, while in England, they also interpreted the game during the 1770s and 1780s.

Twenty-One, still known as vingt-un, appeared in the United States around the beginning of the 1800s during the First World War. To stimulate players' interest, gambling houses offered bonus payouts, including a ten-to-one payout if the player had an ace of spades and a black Jack in their hand. This hand was called a "blackjack", and the name stuck.

The first American rules were published in 1825 but were only a reprint of the 1800 English rules. Over the next few decades, the game evolved into an American variant renamed blackjack around 1899. In subsequent years, several variants of the game have appeared, many of which you'll find at the best online blackjack sites in the US. Currently, there are more than 100 variations, and we'll explore some of the best and most popular ones here.

Variations of Blackjack

If you're wondering how to play blackjack online, you'll be pleased to hear it's one of the easiest online casino games to grasp. There are numerous variations, but the standard house advantage in blackjack is around 2%, Xinyi Cai[3] proves in his research. You can try to lower with the help of a strategy and blackjack charts. These are very useful to plan your next move depending on your hand and the dealer's up card.

American Blackjack, sometimes called Classic Blackjack, is the most widely played form of the game. The main difference to other blackjack variations is that the dealer gets their hole card (the one that remains face down) before players decide their hand. Other differences include the details of splitting and doubling down. European Blackjack is another more widely played variation. In this game, the dealer receives their hole card after a player decides how to play their cards.

Other popular variations of blackjack include Vegas Strip, Atlantic City, Double Exposure, Switch, and Progressive Blackjack. If you're keen to learn how to play blackjack online, understanding the different variations is beneficial.

Before you decide which of the best online blackjack games to play, consider your skill level. For beginners, an excellent place to start is American or Classic variations. If you'd like to experience a more social and interactive version of the game, remember that many of the best online casinos offer plenty of live dealer action.

Vegas Strip Blackjack

Vegas Strip Blackjack

Vegas Strip Blackjack is named after a stretch of South Las Vegas Boulevard that is famous for its many hotels and casinos. It is also one of the most played blackjack variations on "The Strip". Initially, you could only play this version in Las Vegas. However, now you'll find it is one of the best online blackjack games at most major casinos.

This blackjack variation has a low house edge and beneficial exceptions to the standard blackjack rules. Vegas Strip Blackjack is played with four decks of cards that the dealer shuffles after each hand. Gameplay includes dealer peek, insurance, splitting, doubling, and other exciting features. Single and multi-hand variants are also available, with a house edge of 0.36%.

The game starts when you place your bet on any hand position you want to play. Some versions allow you to play more than one hand simultaneously. Once you've made your bet, you receive two face-up cards, while the dealer receives one face-up card and one facedown. If the dealer's face-up card is a 10, they will check for Blackjack. If it is an Ace, then you'll be offered insurance against the dealer having Blackjack, which costs half your original bet. If the dealer goes on to have Blackjack, your payout is 2:1.

The round proceeds as usual if the dealer doesn't have Blackjack. Each hand has three main options: Stand, Hit, or Double. Double down is permitted on every hand, but only after the dealer deals the first two cards. It's also possible to split your hands if the first two cards dealt to a hand have the same value.

Atlantic City Blackjack

Atlantic City Blackjack

Atlantic City Blackjack is another well-known variation of the game that's named after a top gambling destination. The game's basic rules are similar to those in the classic blackjack game but are more player-friendly. The distinguishing feature is that the game uses eight decks of cards. However, there are some subtleties you should fully understand.

It's possible to double down on just about any hand total and is also possible after you've split your hand. However, it would help if you remembered that doubling down can only be done on your initial hand. Atlantic City Blackjack rules are also very relaxed when it comes to splitting. For example, you can take advantage of the split option up to three times, with one exception being matching Aces - you can only split these once.

Late surrender is another unique feature of this variant. The benefit is that it lessens the house advantage further. This rule means you can surrender your hand after the dealer checks their hole card. Atlantic City Blackjack has a house edge of 0.36%.

European Blackjack

European Blackjack

European Blackjack was one of the first types of blackjack games. Like all the best blackjack games, the objective is to beat the dealer by having a hand worth more points than the dealer's without going over 21. Odds in the game are set at 3/2, while it has a house edge of 0.39%.

You play the game using two 52-card decks, which increases the house edge. There are some subtle differences with this variation. For example, the dealer deals or consults their second card after players have played their hands. You can take the insurance side bet if the dealer's up card is an ace. The dealer doesn't peek at their cards and allows players to play out their hands before they check for blackjack.

There are far fewer opportunities to double down in European Blackjack. You can only double on hands with a 9, 10, or 11 value. The options for splitting are also stricter. You can split once in the game and only 10-value cards of the same face/value. Some European Blackjack games offer a surrender option, which allows you to give up half of your bet if you don't like your hand.

Double Exposure

Double Exposure Blackjack

Double Exposure Blackjack is a variant of the classic game, but with the crucial difference of both dealer's cards being face-up. Usually, this difference would balance the odds in your favor; however, other differences level things up. Let's look at these in more detail.

In many games, having a blackjack pays 3:2. However, in Double Exposure Blackjack, it pays 1:1. The insurance option available in many of the best online blackjack games is not there, making the payouts equal to -1 to 1. Something else you can't use to your advantage is the push when you and the dealer have a tie.

Other differences in Double Exposure Blackjack tend to vary depending on the platform you're using. Some allow you to double down only if you have a hard 9, 10, or 11. With some, you can't get a natural once you split your hand. This means that if you have an Ace and a 10-value card, you can't count this simple 21-value hand as blackjack. Therefore, if the dealer gets a natural, your hand won't win or tie against it.

Blackjack Switch

Blackjack Switch

Blackjack Switch is a variant with a unique twist. You play the game with two hands, with the option to switch the second card dealt to each hand. Such a feature adds an extra layer of strategy, which you could use to increase your chances of winning.

The game is played with six or eight decks; the dealer must stand on all 17s. You're permitted to split any pair, including Aces. However, you can only double down on 9, 10, or 11. Each hand has a separate bet, which must be identical amounts.

The primary rule of Blackjack Switch is that you can switch the second card dealt to each hand if you want to. For example, if you have a king and a 6 in one hand for a 16 and a jack and a 5 in the other for a 15, these would be bad hands. When you're playing Blackjack Switch, you can switch out the king for the 5, giving you a 20 in one hand and an 11 in the other. The odds for this game are set at 1/1, while the house edge is 0.58%.

Progressive Blackjack

Progressive Blackjack

Progressive Blackjack is simply blackjack with a side bet for a progressive jackpot. If you decide to place the side bet and a specific combination of cards appears, you can share the jackpot with others who put the same side bet. The game's general rules are the same as classic blackjack but with the added excitement of the potential for a jackpot win.

Once one or more players have won the jackpot, it accumulates again. Typically, a small fraction of each player's side bet goes into the progressive jackpot pot, while the rest of the sum contributes towards the pot's seed. It works this is way so the jackpot doesn't have to start accumulating from scratch should anyone win the entire jackpot. Instead, the jackpot resets to a predetermined amount and starts building from there.

There are progressive blackjack variations that you can play with multiple hands. This way, you can place up to 5 bets and play 1 to 5 hands, improving your chances of hitting the jackpot. You should note that some variations that only allow side bets for one hand.

Spanish 21

Spanish 21

You play the game of Spanish 21 with a deck of 48 cards. From the standard deck of 52 cards, the four 10s are removed. The fewer number of cards gives players a slight advantage. In addition, the chances of the dealer having a natural 21 are lower.

Like all online blackjack games, the goal is to get a hand value of 21 or as close to it as possible. Another key difference with this variation is that you can surrender your hand after the dealer checks for blackjack. This isn't an option in traditional blackjack. The advantage of surrendering is that you can save half of your bet if your hand is likely to lose. It also gives you a better chance of staying in the game and winning in future hands.

Players can "resplit" their hands and double down on any hand, no matter how many cards are dealt. You can even double down after splitting or resplitting. Another key feature of the game is that if you hit 21, you will always win, and blackjack always beats a dealer blackjack. Although, hitting a blackjack is harder because of the lack of 10s.

Multi-Hand Blackjack

Multi Hand Blackjack

Multi-Hand Blackjack is a recent addition to the list of best blackjack games. Most of the rules follow classic blackjack gameplay, barring one key exception: players can play multiple hands at once. The number of hands you can play varies. Some games allow 2, while others allow 3, 4, or 5. It's usual for each hand to have the same bet size. However, some operators offer the option of different bet sizes.

You play the hands sequentially, starting at the first base spot and moving left. The game generally involves six or eight decks, with a payout of 3:2. Specific rules of the blackjack variant tend to vary from casino to casino.

In some, dealers must stand on soft 17; in others, they must hit. Likewise, surrender is allowed in some, and players can take insurance against the dealer's ace in others. Such differences mean it's best to double-check the rules before choosing which multiple-hand format to play.

Bonus Blackjack

Bonus Blackjack

Bonus Blackjack is another recent addition to the line-up of the best online blackjack games. It shares most of the rules with the traditional card game but with one significant difference. There is the possibility of getting a bonus should a blackjack be formed with certain cards at relatively high odds.

The name of this game is somewhat misleading. It is not merely a bonus in a game of blackjack. It is a variant that features interesting side bets alongside the traditional blackjack bets. However, the real star is the optional side bet since it offers the highest payout of all blackjack bets.

As mentioned, the rules are basically the same as classic blackjack. Dealers must hit on a soft 17, and players can split, double down, and take the insurance bet. However, in this variant, you can't surrender. If the dealer deals you any two suited cards, the Bonus bet, if you make it, pays 5:2. A Jack and an Ace will pay 25:1, while a Jack and an Ace of Spades has a payout of 50:1.

Free Online Blackjack Demo

Most operators offering online blackjack for real money will have free demos. The main advantage of playing for free is that you can try new games without risking your money. This is ideal if you're a newbie to the game of blackjack or if you want to try one or more of the many variations of the game.

For new blackjack players, free demo games provide the perfect practice opportunity as you're not facing any risk regarding your money. You can bet on sessions using the free credits that online casinos offer. If you lose, you reset the game and get back the same number of credits. Another key advantage of free blackjack games is that you can try out all the available features. If you want to try a new strategy, you can test its effectiveness without risk.

You can find these blackjack variants at various legitimate online casinos in the US. Before making any recommendations, we prioritize finding licensed operators and selecting games that offer a safe and fair experience.

Something else we check is whether an online game can be legally played within a particular territory, as online gambling is not legal in all jurisdictions. Digital encryption is another critical factor to check. When an operator uses it, players' personal information is protected, and all financial transactions will also be encrypted for players safety.

RNG Games

RNG stands for Random Number Generator, and it is at the heart of the modern online gambling industry. It is prevalent in many online casino games, including blackjack. The purpose of the RNG is to ensure random, unpredictable outcomes, guaranteeing fairness for everyone who plays.

In the case of online blackjack variations that run on RNGs, there is no human to shuffle and randomize the card order. Instead, RNG blackjack games use algorithms and mathematical formulas to ensure each card that appears on the virtual felt is dealt at random. These types of games can be played at all the best online casinos.

Live Dealer Blackjack

Live dealer blackjack games use real human dealers, real cards, and a table. The games use live HD video streaming, which allows you to connect to the dealer and view every card as it is dealt in real-time.

Online live dealer games have come on in leaps and bounds in recent years, with multiple camera angles, zoom-in features, and the option to chat with the dealer. You can play live dealer blackjack at most reputable online casinos, and it's as close to the real thing as you can get from the comfort of your armchair.

Types of Blackjack Games

Blackjack has been played in various countries, and because of player preferences and culture, the game has evolved into many variants. The game's popularity spread throughout Europe, and by the 1800s, it had reached the United States, where its popularity experienced a boom.

Across the country, blackjack was the main attraction and casinos progressively implemented their own rules. They used more decks and added mechanics, making the gameplay more exciting. The casinos introduced many of the innovations to make the game more profitable for them. In the 1930s, splitting pairs appeared, while the hole card rule appeared in the 1950s.

The emergence of online blackjack games in the late 20th century revolutionized the gambling world. It didn't take long for blackjack to embrace the new platform. RNGs to ensure fair gameplay and sophisticated graphics that replicated the casino experience meant the popularity of online blackjack soared. The introduction of live dealer games took the popularity of the online game to another level.

The odds of winning blackjack center mainly on the variation you choose to play, which makes understanding the different game types and their odds essential. In addition, the side bets and additional options can also change the odds of the game and the money you receive.

Most blackjack games have a house edge of less than 1%. This means the casino makes less than $1 on every $100 bet on the game. The house edge goes up with each deck used, and it goes up if you get paid 6:5 instead of 3:2 on blackjack.

Odds, Probability and Payouts

Odds and probability are terms often used interchangeably; however, some significant differences exist. Probability tells you how likely it is to win a game. The probability of a game is calculated by dividing the approximate chance of winning by all possible chances. Odds are a representation of chance and are calculated by using the probability of winning and the probability of losing.

The odds in a blackjack game don't strictly express the chance of winning but rather the payout for each bet. Probability typically shows a chance, while odds only show the money you receive. With the right approach, the player has a favorable probability of winning over the house. Systematic management of the bet size relative to a player's bankroll is an important part of the strategy.

Ralph Vince and Qiji Zhu[2] suggest that the Kelly betting system proposed by Thorp is the most systematic money management system. It consists of betting a fixed percentage of the player's bankroll and is shown to have the highest expected growth rate. We suggest you check it out because, unlike the Martingale, it doesn't call for doubling the bet size on each consecutive losing play.

Besides standard types of blackjack, there are side bets/additional options that can also change the odds and money you receive. Here are a few examples:

  • Insurance: Gives you the chance to break even should you lose the main bet.
  • Surrender: Late surrender is offered most, meaning you can surrender half your bet after the dealer checks their hand.
  • Number of decks: The house edge can be almost 0.563% higher in an 8-deck game.
  • 21+3: The house edge for 21+3 starts from 6.29% and goes up to 8.78%, depending on the number of decks you're playing with. The lower the number of decks, the higher the house edge.
  • Perfect Pairs: The bets in this game have one of the lowest blackjack probabilities. The house edge is also high, from 2% to 11%.
  • Doubling: The paying odds on a blackjack win stay the same as classic blackjack, 3:2; however, you stand to win two times because you've placed two bets.
  • Splitting: Blackjack winning odds stay the same when you split.
  • 6 to 5 odds: These odds pay you less than 3:2 odds, only 1.2 times your wager.

Popular Online Blackjack Software Developers in the US

You'll find some of the best software developers offer a variety of blackjack games, although some are better than others. Brands like International Game Technology (IGT) and Scientific Gaming design and create many of the best online blackjack games titles you'll find at US online casinos.

These software developers determine the payouts for each variant, not the casinos, as many think. The game creators also program and build the RNG software contained within each title. To ensure fairness for players, most online casinos have these RNG systems tested by independent third-party auditors like eCOGRA, iTech Labs, and Gaming Laboratories International.

Software Developer Established All Blackjack Games: Most Popular Blackjack Play at
1996 26 BetRivers
1983 21 BetMGM
1999 3 Bet365
1990 3 Golden Nugget

We've scoured the internet looking for reliable blackjack developers, and the ones listed have launched hundreds of high-quality blackjack games over the years. In addition, these blackjack software developers are safe and licensed by reputable regulators in the states where they're available. It's rare to find all the listed software developers featured by one operator. So, if you're looking for a specific game or a top casino software developer, checking what's on offer before you sign up to any casino site is wise.

Responsible Gambling

For many blackjack players, gambling is an entertaining fun experience. However, it's important to recognize there are risks involved. Anyone can fall prey to a gambling disorder, so it's essential to follow responsible gambling practices.

There are no federal laws related to online responsible gambling. However, each of our recommended casinos offers a range of tools to support players who want to enjoy gambling safely. These include deposit limits and self-exclusion. Several responsible gambling organizations across the country who offer support and help for players as well as training for operators, the foremost of which is the National Council on Problem Gambling.

Frequently Asked Questions

We're almost at the end of this page, and we hope we've covered everything you need to know about online blackjack games. We also appreciate you may still have some questions. You'll find the answers to some of the most common questions coming right up.

What are the best online blackjack games in the US?

This is quite a subjective question, but you'll be pleased to know there is a huge variety of online blackjack games available. Knowing a little about each game and how it works makes choosing the best blackjack game easier. It does, however, depend on your preferences.

What are the different variations of blackjack?

Blackjack has always been a game of variations, depending on where you play. Nowadays, whether you play online or at a brick-and-mortar casino, you have plenty of blackjack variations to choose from. Choose from games such as Vegas Strip Blackjack, Atlantic City Blackjack, European Blackjack, Double Exposure, Blackjack Switch, Spanish-21, Multi-Hand Blackjack, and many more.

What types of blackjack games are there?

Over the years, a wide variety of blackjack games have evolved. Two major blackjack types have been developed for players who want to play online. RNG blackjack games use random number generators to provide complete randomness and ensure fair gaming. There are live dealer games for players who prefer a more interactive and casino-like experience.

Is computer generated blackjack rigged?

No, computer-generated blackjack is not rigged at all. Legal online casinos are licensed by state government agencies and are reputable gaming operators. The blackjack games available use Random Number Generators, which ensure the games are random and fair. These RNGs and the games are routinely checked and audited by independent third-party auditors to ensure everything is transparent and impartial.

What is the difference between blackjack and Spanish 21?

The critical difference between blackjack and Spanish 21 is that all 10s are removed from the pack, leaving 48 cards in each deck. Jacks, Queens, and Kings count as 10. Aces count as 1 or 11, whichever is to your advantage. With no 10s in the pack, hitting a blackjack is much harder. Spanish 21 also has a much more comprehensive range of side bets, including the insurance bet, which pays 2:1.

What is the best version of blackjack to play online?

With so many to choose from, this can take time to decide. Take Vegas Strip Blackjack, for example. It's a very popular game form originating on the Las Vegas Strip. The rules when doubling, splitting, and placing side bets are more liberal, which some players might prefer. Other variations will have slightly different rules and requirements, so once you understand these, you can decide which is the best version.

What are the odds of winning from the best online blackjack games?

Blackjack has excellent odds of winning, with a house edge as low as 1%. If you're playing the recommended 3:2 version of the game, your chances of winning can be as high as 33.33%. An important point to remember is that side bets have a higher house edge, giving you less chance of winning.

Conclusion – Play the Best Online Blackjack Games

Blackjack is a game I love playing, and it's no surprise that so many players love it as well. It's an exciting game, filled with anticipation, and one of the easiest for beginners to play. An excellent place to start is with the classic blackjack game, and once you've mastered the basics, you can quickly move on to any of the other variations.
