Basic Blackjack Rules

It’s Simple: Get to 21

There are a number of factors that make Blackjack one of the most popular and most played casino games; not only can you improve your chances of winning by learning tricks and strategies but it’s one of the most simple and easy to understand casino games around. The aim is 21. Get closer to 21 than the dealer (without going over) and you win.

The real aim however, is to get Blackjack. This isn’t just where the sum of your cards adds up to 21 but where you have either a 10 or a face card (King, Queen or Jack) as well as an Ace; Blackjack!

Blackjack is a card game and a table game that lands in the category of comparison games and cash games (banking games). “Comparison game” means that the game focuses on the comparison of the value of cards, not the actual card game. The result is determined by comparing the player’s cards against the dealers. That brings us to our next term, “banking game”. This means that players are not playing against each other, rather they are trying to beat the dealer.

How it Works

There are different kinds of Blackjack, with small variations but in general, the players will be dealt two cards (face up) and the dealer will be dealt one visible card (their second card might be dealt at the same time, face down, or they might draw it later, depending on the type of Blackjack in play). Based on the sum of your two cards, and taking into account whatever card the dealer has, you then decide whether you want to ‘hit’ and draw another card (to bring you closer to 21) or ‘stand’ and stay as you are.

Extra Options: Split and Double

If you have two identical cards you can even choose to ‘split’ which will split your hand into two hands (so you’ll have to place your stake down again, doubling the amount) or if your cards total 9, 10 or 11 you can choose to ‘double down’ by doubling your stake before drawing another card. This means, if you get a 10 you have a good chance of winning, and have doubled your potential wins. Both of these options give you the chance to win double your original hand, however it means risking twice as much too, so choose wisely! For example, having two tens (20) is a great hand in itself, so it’s not often advisable to split them as you risk twice as much and might get two much worse hands.

Blackjack Dealer

The dealer has a very central role in Blackjack; it’s the dealer you are playing against and they are also who controls the game. The Blackjack dealers are responsible for dealing the cards, handling the chips and making payments. When you play online, you will meet a computerized dealer who mixes the decks before each game and is connected to a random number generator, or if you are playing Live Casino, you’ll watch a video feed of a real table and a real dealer, dealing real cards in real time!

Easier to Win at Online Blackjack

It’s much easier to win Blackjack online for several reasons. Firstly, you have more variations of the game to choose from and you can play at a table that’s at your skill level. Secondly, you have the opportunity to play Blackjack for free at many casinos online. There is no live casino in the world that will allow you to play for free! But, most importantly, when playing against a computer at least, there are no other players on the table to mess up your strategy. One of the more frustrating aspects of Blackjack is, even though you’re playing agains the dealer, what cards you and the dealer get, depends somewhat on how the other players act. If they hit or stand with no respect for strategy it can affect the whole table, so this is something you don’t have to worry about when playing Blackjack online.

Live Casino Blackjack

There are two ways to play Blackjack online. One is via a computer generated game, there is no physical dealer and no set amount of decks; everything runs from random number generators. Alternatively there are Live Casinos. This is where there is a casino studio, filming and sending a live feed to online casinos so you can bet on a real table, with a real dealer in real time. Many players can play at the table together and it basically gives the feeling of a bricks and mortar casino from the comfort of your own home. Here there will be a set amount of decks, with shuffle time (or an auto shuffle machine) and that human interaction.

Mobile Blackjack

Most casinos are aiming for a 50/50 divide of players playing on desktop and mobile devices, so it stands to reason that they need to offer a good range of games on their mobile casino. Most casinos have a mobile casino and most mobile casinos have some kind of mobile blackjack game available to play. Whether it’s a Live Casino mobile Blackjack or standard mobile Blackjack game will vary per casino but simply login and head to the table games section on your mobile or tablet to get playing Blackjack on mobile!

Playing Blackjack on mobile devices

Playing Blackjack on mobile devices is somewhat limited, but continues to grow on a daily basis. More and more online casinos begin to offer mobile casinos where you can play Blackjack along with other casino games. Mobile Blackjack works just like regular online Blackjack but has been adapted for use on many popular mobile devices. It is simple and easy to play mobile Blackjack for quick entertainment – on the bus, at home on the couch or while waiting on the train; anywhere, anytime. Mobile Blackjack games allow you to play Blackjack online for real money on your smartphone or tablet; that includes iPhones, iPads and Android devices.

Blackjack Strategy

Blackjack is one of the casino games that have many strategies and systems that work well. There are several Blackjack strategies available, each with varying qualities. If you want to go this route and use a strategy while playing Blackjack, it’s important to choose the right one. Otherwise, you risk using a faulty strategy that may actually lose you money instead of help you win.

Blackjack Strategies and Systems

Strategies and game systems can often be confusing, although there are clear differences between them. Basic strategies are complete game play, while game systems can be part of the strategy they are not the complete part. A strategy is a mindset from the player’s side. A plan that may include guidelines for the player to choose when to bet, when to hit and when to make all other decisions based on this strategy. If this strategy consists of a game system including a mathematical table, this will dictate how the player acts as the game progresses. A game system is an elaborate investment plan for Blackjack scenarios. Strategies do not guarantee profit; they merely increase your chances of winning. No strategy or game table or system can actually guarantee the player profits. This is important to understand. Chance plays a large part in the outcome of a hand of Blackjack or any other casino game for that matter. A strategy, or a game system is simply a guide that can aide in the players decisions that increase the chances of winning. There are lots of game strategies and game systems to take advantage of. Here at JohnSlots, we have put together a list of classic and new strategies on this page. You can even apply these strategies and systems right here at by playing free Blackjack. Scroll up to the top of the page to try one of our popular Blackjack games.

Perfect Strategy: Blackjack

Also known as Basic Strategy, Perfect Strategy is the most popular method of playing Blackjack for anyone who wants to win. This is a set strategy that determines whether you should stand, hit, split or double based on whatever card combination you have versus the dealer. There is a popular table that shows you exactly what action to take. Memorise this and act according to it’s instructions and you give yourself the best chance of winning. It’s not guaranteed to make you win every hand but allows you to make decisions that give you the best chance of winning over time.

Most players at real live casinos play Perfect Strategy, watch when they hit, stand, double or split and you’ll see most follow this to the letter. Blackjack Perfect Strategy is simply based on logic and probability. For example if the dealer has a 2 and your cards, added together total 12, what is the best course of action? Perfect strategy states you should HIT. However if you have 12 and the dealer has 4, Perfect Strategy says STAND. Interestingly, it says you should always SPLIT two Aces and two 8s.

From Beginners to Professional Blackjack Players

The path from novice to professional doesn’t need to be a long one. With a little training, a little talent and some patience, you can go from beginner to pro in just a few short weeks. It’s easy to become a Blackjack professional when you play online. On the internet, players can quickly and easily learn the skills to become a pro and start winning large sums of money.

Online and Offline Professional Blackjack Players

It’s important to note that an online Blackjack pro and a live casino one differ greatly. The professional who plays in a live casino often has a mathematical background. Many of the strategies including card counting and others are tailored to playing in live casinos. These types of pros avoid online casinos as much as possible since their strategies will not work as well. It’s also important to note that when playing at a Live Casino, what you do affects others at the table so it’s important that you’re playing with people who are on the same page and don’t make risky decisions.

Online Blackjack Professionals

There are some professionals who are good at both online and live casino Blackjack. One is a man by the name of John May. He was completely fascinated by online Blackjack. May, unlike many of his live professional counterparts, managed to profit and perfect a strategy for online Blackjack. We have him to thank for his theories and he has been generous enough to share them with everyone. May has written books and developed an original Blackjack theory and strategy called the takeover. Instead of counting cards and using assumptions, May chose to focus on controlling the boards and uses lots of coverage’s. His knowledge is very important to the new generation of Blackjack players who are more likely to play online versus live casino Blackjack.

Professional Blackjack Tips

According to John May, the key to successful Blackjack hands is using the gaming advantage. You can read more about this in his book “Get the Edge at Blackjack”. Peter Griffin, a pioneer in live casino Blackjack, once told me that the best way for a player to gain a long term advantage is to collect information about the cards that are dealt and use this to place varying bet sizes. This leads to advantage in the game over the long run. A third Blackjack pro, Bill Zender, strongly believes that different approaches to the game, will suit different players. He says that each player must try and discover new strategies and find the one that best suits them.
