Anyone that has ever picked up a deck of cards must have played “21” at least once. The wonderful card game of Blackjack has been a player-favorite for decades, and over the years it has become the most popular card game in online casinos. The combination of skill, chance, and strategy is what draws the attention of many casino players all over the world to the game.
Maybe you have seen movies like 21, Rainman, or The Card Counter, and got inspired to pick up the game and learn how to count cards at Blackjack. However, let our experts warn you beforehand: casinos don’t like it when you count cards, and online casinos go to extreme lengths to make sure it is as hard as humanly possible. They use 6 to 8 decks, switch decks halfway, and take many more precautionary measures.
Anyway, the game of Blackjack is played between a dealer and player(s). Every player, including the dealer, receives two cards every game round. The cards of the player(s) are dealt face up, while only one card of the dealer is visible to other players.
The goal of the game is to get a hand score as close to 21 as possible. After receiving your cards, you have the chance to “hit” to receive another card from the dealer or “stay” to not receive any more cards. If any player’s hand total goes over 21, it is a “bust” and the dealer automatically wins.
There are multiple rules and options, such as splitting, doubling down, and taking insurance, but these are more advanced Blackjack strategies that we will discuss later in this guide.
Blackjack in its current state is a combination of different card games played by the Romans, Chinese, and ancient Egyptians. The game derives from the French casino game “Vingt-et-Un,” meaning twenty-one, and was brought by European settlers to the New World of North America in the 18th century.
The game back then was a bit different than how it is played today. American casinos in the 19th century would pay out a bonus of ten to one if the player managed to hit a Blackjack with an ace of spades and a black jack. This bonus payout was later removed, but the name of the game remained the same ever since.
Playing the game became increasingly popular during the Great Depression in the 1930s, after the state of Nevada legalized gambling to accumulate tax revenue. The game was an incredible hit and took the United States by storm.
Although Blackjack was mainly an American casino hit, the game quickly crossed borders and became popular with Canadian and other players across the globe. The rules of the game haven’t changed in all these years, but due to the release of online Blackjack, many new game variants have been released.
Blackjack is a game where the player is up against the dealer and where the goal is to get a hand value as close to 21 as possible, without going over it.
Aces have a value of 1 or 11. Kings, queens, jacks, and tens have a value of 10. All other cards have their initial value (i.e., a 2 is worth 2, a 6 is worth 6, a 4 is worth 4, etc.).
The game starts as soon as the cards are dealt. Every player receives two cards face up. The dealer then deals two cards to him or herself, of which the first one is dealt face up and the second one is dealt face down (the hole card).
After all cards have been dealt, the players can decide whether they want more cards (hit) or no more cards (stay). Additionally, they have the option to double their bet (double) or split their cards into two separate hands (split), which is only possible when they have two identical cards (i.e., two queens, two sevens, two eights, etc.).
After all players have decided on their moves, it's the dealer’s turn. The dealer always has to hit until he or she has a hand value of at least 17 or higher. This means that in most Blackjack variants, the dealer has to take another card at 16, even if this has a high chance of “busting” the dealer.
There are three outcomes during the game: either the player wins, the dealer wins, or it's a tie, also called a “Push.” In the last case, the player’s bet is returned. The best scenario for the player is to win with a blackjack by receiving an ace and a card with a value of 10. In this case, we speak of a “Blackjack,” and the player is paid out in a 3:2 ratio.
Blackjack is a very straightforward card game. The only thing you have to do as a player is to focus on beating the dealer. This means you don’t have to worry about the hand values of other players, as they all try to do the same. Unlike poker, which has thousands of different strategies, Blackjack only has a handful.
If you are new to the game, we recommend mastering the basic strategy first. The most important part is knowing when to hit, split, stay, and double.
The basic strategy is applied by players across the globe and is based on probability calculation. If you receive any hand with a value between 5 and 15, you hit. If you receive a hand with a value between 17 and 21, you stay.
Now, this is fairly simple, but it gets more complex with splits and doubles. Splitting your cards is often the best choice whenever you receive two cards with the same value. However, you should always take note of the dealer's face-up card, as it's important to know what the dealer might have.
To play online Blackjack, you will have to follow the simple steps outlined below.
Whenever you want to play, you’d have to find a reliable online casino first. A reliable online casino is licensed and regulated by the Alcohol and Gaming Commission Ontario (AGCO). It is allowed to market its game offerings to Canadian players. All casino sites mentioned on our site are licensed and regulated.
Before you sit down at the Blackjack table and let the dealer deal cards to you, it is wise to familiarize yourself with the rules. Note that there are many different variants, so be sure to know the rules of the exact Blackjack game you’re playing.
Once you’ve got the hang of the rules and found an online casino to play at, it is time to take a seat at the tables.
Before you’re dealt your cards, you have to place a bet. Your bet should adhere to the table limits and should be in line with your bankroll or playing budget.
The odds and payouts are fairly straightforward. Hitting 21 will give you Blackjack. The highest “normal” hand value is 20, which you can reach with two face cards, two tens, or a face card and a ten. Most Blackjack games have a Return to Player ratio (RTP) of around 99%.
There are loads of online Blackjack variants, such as Pontoon, Spanish 21, Switch, and Perfect Pairs Blackjack. Below, we will highlight some of the most played games.
Classic Blackjack is the most basic form of the game. The goal is to reach a hand value as close to 21 as possible. The dealer has to stand on 17 and hit at 16.
Spanish 21 is played with 48 cards instead of 52. Additionally, the player wins automatically when he or she is dealt a Blackjack. There are no pushes in this version of the game.
In Live Blackjack, the game is presented by a real human dealer and streamed from a professional casino studio. The player can follow all the action with his or her own eyes as the cards are being dealt in real-time. Popular live games include Pragmatic Play Live’s ONE and Evolution Gaming’s Lightning Blackjack.
Pontoon is officially a British version of Blackjack. The standard rules apply, but the terminology is a bit different. In Pontoon, one of the players is assigned as the “Banker,” who basically takes over the role of the dealer. Whenever the banker hits 21, he or she calls a Pontoon and collects double the amount every player has wagered.
American Blackjack is the same as the regular one, with the only important main rule that the dealer receives two cards, one of which is dealt face down (hole card).
Super Fun 21 has a few additional game rules, such as the fact that aces can be split or doubled down upon. Players can surrender after a failed double and are allowed to split pairs up to four times. Super Fun 21 also utilizes the Six-card Charlie rule, where players automatically win if they have a hand of 6 cards with a score of 21 or lower.
In Blackjack Switch, players receive two hands, so four cards in total. They are allowed to switch the second card of each hand to increase their chances of winning. This variant requires the player to place two identical bets per game round.
In Zappit Blackjack, players can “zap” any of the two cards they get dealt and replace them with new ones. The downside of Zappit is that the player won’t receive a 3:2 payout whenever a Blackjack is hit.
Perfect Pairs Blackjack is the same as the original game, but with an additional twist. The player can place a so-called side bet separately from the main bet. The player bets whether the dealer or the player will receive a “pair” of the same two cards. These can be two cards of the same color or suit.
This Blackjack game derives from the way it is played in Atlantic City. In Atlantic City, the dealer can check whether he or she has a Blackjack and has the option to stay at 17. Players are allowed to split their hand up to 3 times.
European Blackjack follows the same rules as the original game, but the dealer deals his or her cards face up. However, the second card of the dealer is only dealt when all players are done making their decisions. Additionally, players can only double down when they have a hand value of 9, 10, or 11.
Infinite Blackjack is a game with 4 side bets: Any Pairs, Hot 3, 21+3, and Bust It. The game is played with the Six-card Charlie rule, meaning if a player reaches a hand of 6 cards without going over 21, he or she instantly wins.
This Blackjack game looks a lot like Spanish 21. However, in this variant, the player can place his or her first bet after having seen the dealer’s upcard.
In this Blackjack game, a progressive jackpot is added that can pay out life-changing amounts of money. However, players are required to place a special Ante bet to stand a chance of winning this jackpot.
This is a bit of a weird version of Blackjack, where the player doesn’t get any cards at all. Instead, you have to bet on how close the dealer will come to 21. With a correct bet, you can win up to 19 times your current bet per hand.
In Double Exposure Blackjack, the dealer receives two face-up cards. This provides the player with a significant edge. However, a natural Blackjack pays out even money instead of the usual 3:2.
This game basically combines Blackjack with Texas Hold’em Poker. The goal is still to reach a hand score as close to 21 as possible, but both the dealer and player can use two community cards to increase their hand values.
Triple 7s Blackjack is another progressive jackpot game. The goal is again to reach a hand value as close to 21 as possible, but whenever the dealer or player reaches a Blackjack with 3 sevens, the player receives a significant payout. In most cases, players are required to place an Ante bet to be able to win the jackpot.
This game follows the traditional Blackjack rules. It is played with 4 decks of cards that are shuffled after every game round. The big difference is that if the dealer is dealt an ace or ten, he or she may “peek” for a Blackjack. If the dealer has one, the player instantly loses and the next game round starts.
Big Five Blackjack is played with 5 decks. The dealer has the option to surrender on a soft 17. All other regular game rules apply.
Vegas Downtown Blackjack is played with two decks that are shuffled after every game round. Players can play up to five hands simultaneously, of which every hand plays separately against the dealer. The dealer receives two cards, one of which is dealt face down. If the visible card of the dealer is an ace, the player has the option to take out Blackjack.
Chinese Blackjack is known by many names, such as 21 Point, Ban Nag, and Ban Luck. These games look a lot like the traditional game. However, the best hand contains two aces (Ban-Ban), which beats all other combinations. The second-best hand is a hand consisting of an ace and a card with a value of ten, called Ban-Nang.
This online blackjack game is played in the same way as the original game. However, players have the option to surrender after the first two cards have been dealt. By doing this, the player receives half of his or her initial bet back.
Blackjack originally started as a French game of chance. However, nowadays we mostly use American English terms. Below, we will explain the meaning of several words that you may encounter when playing online Blackjack.
Yes, there are many casino websites that allow you to play free Blackjack games in demo mode. In most cases, you will have to sign up for a casino account first in order to be able to play for free. There are also sites where you can practice and play without registering at all. On our site, we also offer a series of free online Blackjack games.
All you need for playing free Blackjack games and for real money, is a computer, laptop, mobile phone, or tablet with a stable internet connection. Furthermore a player account at an online casino or gambling website that offers the game to its players. Additionally, you may want to use a ‘’cheat sheet’’ so that you know exactly what to do in which situation.
Although it is completely legal to count cards at online Blackjack, it won’t help you that much. As often 6 to 8 decks are being used and these are being reshuffled every time half of the shoe is dealt.
Yes, in most cases you have a bigger chance of winning by playing Blackjack online compared to playing the game in a brick-and-mortar casino. Key reasons include better rules in favor of the player and the option to use casino bonuses and promotions.
Yes, unlike playing slots, where you just press a button, wait, and hope for the best, playing online Blackjack requires a strategy in order to win from the dealer. If you don’t know what you’re doing, you’re unlikely to profit from playing.
