The Gorilla was of the opinion that an expansive description of the game was necessary for players who were curious about trying it out.

And as it happens, he is in the mood to tell you all about it. Luckily enough for beginners, online blackjack isn’t rocket science; it’s a game that one can quickly grasp and go about having fun, and possibly earning some dough. Once you go through this guide, you will be able to understand the basics about the game and who knows, it may be only a matter of time before you become a Blackjack guru like Edward O. Thorp.

What is Blackjack?

It’s not uncommon to encounter people (mostly casino amateurs) who don’t know what Blackjack is leave alone its alternative moniker, ‘Twenty-one’. The credit for the game’s invention goes to the Americans who went on to popularize it to the extent that it became a global hit. There is hardly a casino in the world worth its salt that operates without blackjack tables on its premises.

Blackjack in a nutshell:

  • Blackjack is essentially a game that involves comparing cards.
  • The typical traditional set up for a game involves a dealer surrounded by several players who compare cards with him/her in turn.
  • The players compete with the deal but as a rule, don’t compete with each other.
  • Playing the game requires one or more decks of 52 cards.

In online casinos, you have an option to play with the computer, or with live dealers with actual professionals.

Understanding the Basics

The game begins once the dealer (the computer or live croupier) hands two cards to himself before dealing two cards to every player on the table as well. Usually one of the dealer’s cards will be facing up and the other down.

  • All the cards with numerals on them take up the numerical value embossed on them i.e. (2 through 10)
  • Face cards, on the other hand i.e. King, Jack and Queen, have a value of 10.

Aces are worth either 11 or 1. It at this juncture that beginners need to be acquainted with a number of terms;

  • Hand value – This refers to the sum of all the card values you possess.
  • A soft hand – Refers to a hand that has an Ace valued at 11. The game allows a player to draw an additional card to boost their hand. The reason why a hand value of 11 is called soft is because it won’t bust if a player takes an additional card.
  • Hard hand – The reason why a soft hand doesn’t bust is because the Ace takes up a value of 1. This then prevents the hand value from exceeding 21. In the event you don’t have an Ace with you then the hand is hard.

The goal of the game is to strive to ensure your hand value gets as close as possible to 21 without busting.


Thus, the goal of the game is to strive to ensure your hand value gets as close as possible to 21 without busting. If your hand value exceeds 21 you lose the bet immediately. Upon completion of the player’s hand, it will now be the dealer’s turn. The dealer can, however, fail to play in the event the player has received a blackjack or has a busted hand.

The dealer will then proceed to reveal the card which customarily has a total of 17 or more points. The players on the table can beat him by;

  1. Reaching a higher final score without exceeding a hand value of 21.
  2. Receiving two cards that have a hand value of 21 which the dealer’s cards can’t match. This phenomenon is often called a ‘natural’ or a ‘blackjack’.
  3. Holding out till the dealer’s hand value surpasses 21.

Should any of the above three outcomes take place while you’re playing, feel free to celebrate as best you know how before getting back in there. Nevertheless, in the event the dealer and the player have similar totals (also called a ‘push’), no one loses on that hand.

Gameplay Options

The dealer will hand you your two cards and deal out two for himself. Once you’ve received you cards and have seen what you have to work with, one can make use of the following options;

Gameplay Options
  1. Stand – Taking this option communicates that you are satisfied with the cards you have and require no additional ones.
  2. Split – In the event you have two cards of equal value, this option allows you to play each of them as an individual hand.
  3. Hit – Requesting an additional card.
  4. Insurance – This option serves to protect you from a blackjack from the dealer. Should the dealer turn an Ace, taking this option compels the dealer to view the other card. In the event it has a value of 10 points, you get to win back the insurance bet. You should recognize, however, that this bet may be equal to half your original bet.
  5. Double – This options doubles your bet and procures you an extra card.
  6. Blackjack – You have one ace and a ten card. You win.

Variations of Blackjack Rules

Be prepared to encounter a list of rules the moment you browse you way into an online lobby. While most of the rules that govern the play are similar across the globe, there are certain slight variations that a casino might make.

  • You should, therefore, always keenly read through a casino’s Blackjack rules before you elect to start playing.
  • Doing so will allow you to pick a casino whose rules suit both your preferences and playing style.
  • These variations usually have an impact on house advantage, the manner of play as well the speed with which the game is played.

Such variations include;

Number of Decks in Play

The casino has the option to adopt either multi-deck blackjack or single-deck blackjack. In the event the casino chooses to offer both, then the choice of which one to adopt falls on the players. Land based casinos tend to shun single-deck blackjack given it gives players the confidence to count cards.

It must be mentioned, however, that online casinos don’t have this problem given the shuffle machines continually shuffle the cards which makes card counting unfruitful. The benefit for the house is that the house edge will be marginally higher than the multi-deck option.

Payout for Blackjack

This is one of the most important things to verify before you start playing. The standard rate offered by most online casinos is usually either 6:5 or 3:2. The latter rate will always yield a bigger payout. You should, therefore, always seek casinos that offer a 3:2 rate in order to enhance your winnings.

Blackjack Variants

Browsing through various online casinos will expose you to a diverse range of variants. The most popular include;

Blackjack Surrender

PlayTech’s Blackjack Surrender makes use of six 52-card decks. You can count on all the decks being shuffled before a new hand is dealt. Moreover, the dealer is obliged to stand when the hand value is 17 and a blackjack player is always sure to win.

What differentiates this variant from regular blackjack is that a player has the option to surrender:

  • Choosing to surrender results in the players loosing half his/her bet.

This variant gives players a better deal that the classic game given it allows them to get back half their bet when they sense the house is on the verge of beating them.

Vegas Strip Blackjack

Vegas Strip BlackjackPlayers who’ve visited several online casinos will invariably admit to noticing Vegas Strip Blackjack as being the first variant on offer. Its position at the top of every list is no coincidence given it’s arguably the most popular one.

An achievement that could be explained by its low house edge.One could also consider the ‘surrender’ feature present in some of its versions where players are allowed to surrender and salvage half their bets:

  • An example of a scenario that could prompt such a move is when a player has a hand value of 16 and notices that the dealer has an ace showing.
  • Given a loss could be imminent in such a scenario, the best course of action is to surrender.

Vegas Strip Blackjack also allows players to go head to head in tournaments. An invitation that many blackjack aficionados find very hard to pass up.

Classic Blackjack

This variant follows all the rules of the traditional game and doesn’t grant players a surrender option. What players get instead is a game involving six 52-card decks that are shuffled constantly. Players are given the option to double down the moment they get the first two cards.

The dealer, on the other hand, is obliged to stand on any soft 17. Doubling down only entitles you to one card.


This variant is essentially Blackjack Surrender without the ‘surrender’ option.


Progressive Blackjack

Despite being more common in slot machines, progressive jackpots are now increasingly becoming a regular fixture in blackjack. In order to qualify to make an attempt at winning the jackpot a player must be ready to post a side bet. There is no option to surrender.

Blackjack Switch

The best selling point for this variant is the many favorable odds it gives you.

  • For starters, players have the option to play two hands at the same time while reserving the right to switch two cards from either hand.
  • In order to take advantage of this option, players have to place two identical bets.

The player must, however, contend with the fact that a dealer blackjack gets to beat a player blackjack. Additionally, a player blackjack only pays one to one. Another measure taken by the casino to offset the advantages the player has is to ensure the dealer ties with the player on 22 in case the players strikes 21 or lower.

Formulating a Blackjack Strategy

The first thing one should do before adopting a good blackjack strategy is to let go of all superstitions that one believes have a hand in determining wins or losses. The next step will be to identify the ideal blackjack variant. The guiding principle here is simple; the lower a casino’s house edge is, the higher the odds of choosing it.

Once you’ve isolated one online casino whose house edge is agreeable, the next step is figure out answers to a number of questions. They include;

A number of questions to figure out answers:

  • Can you hit split Aces?
  • How many decks will be used?
  • How does the dealer react to a soft 17?
  • Can you surrender? If so under what circumstances?
  • What are the earnings from a blackjack play?
  • What are the rules regarding doubling on two cards?
  • Is a player allowed to split his hand? How many times can he do so?
  • Can you double after splitting a hand?
  • What is the rule regarding a 5-, 6- or 7-card Charlie?

Once you’ve learned all there is about the rules of the blackjack variant you’re formulating a strategy for, the next step is to find a customized strategy card. A strategy card is a reliable guide that will signal how you should play in response to the dealer’s upcard. This guide will provide you with a specific course of action depending on the hand you’ve got.

You can easily develop your own strategy card by visiting a blackjack strategy calculator online. You’ll thus be able to create a guide to playing that is mathematically supported.
