Are Online Blackjack Games Rigged?

As Online Blackjack is based on chance, you can rest assured that they are completely fair.

On the other hand, online Blackjack games, like slots, utilise a random number generator in and are generally tested by gaming agencies such as eCOGRA. In addition, the presence of professional dealers and safety cameras in live Blackjack games means the games are completely secure.

What is Online Blackjack?

Online Blackjack is a card game played between a player and the dealer where the objective is to get a combination of cards with a total value that is equal to or as close to 21 as possible, without going over this number.

Whoever gets the closest value (the player or the dealer) wins the game. However, a player who exceeds 21, goes bust (loses). 

The card values in Blackjack are very easy to understand. Any cards with numbers from 2 to 10 are valued at their respective numbers.

Jacks, Queens, and Kings all have a value of ten. Aces can be valued at 1 or 11 points depending on what is more beneficial to your combination.

Many people tend to think that Blackjack is any number of cards that make up a total of 21, which isn’t wrong, but it is also called “natural 21” when 21 is the sum of the first 2 cards you’ve been dealt.

In order for this to happen, you will have to get a combination of an Ace and a 10-value card as your first two cards.

Why Play Online Blackjack?

Blackjack has become quite popular at casino sites in recent years, mainly due to the game‘s simplicity and entertainment factor.

Anyone can start playing instantly and enjoy a classic and straightforward card game. In fact, most people are quick to understand Blackjack rules and are comfortable placing bets right away!

If you’ve enjoyed playing blackjack with friends and family in the past, you’ll likely enjoy playing Blackjack online too. 

Play Blackjack from your home

Playing Blackjack online is naturally convenient, as you can play it literally any time. And, with the existence of mobile casinos, you now get to enjoy playing Blackjack on the move.

Claim Blackjack Bonuses

Look for the top casino bonus offers that let you aim for 21 with a good amount of bonus funds after you sign up.

Access to Live Blackjack Online Casino Promotions

The atmosphere and suspense of live dealer Blackjack make it well worth trying out the game. You should also look out for live casino bonuses that help you to get going in the best possible way.

Some of the best Blackjack casinos will also run regular promotions on Blackjack tables, such as reload bonuses, cashback or tournaments!

Play on Multiple Seats at the Same Time

If you enjoy the thrills of a good game of Blackjack, then playing with multiple hands will make it even more action-packed.

When you play Online Blackjack, just look for the casino’s multi-hand games, where can try to beat the dealer with several hands at once.

Blackjack: Did you know?
Blackjack has the best odds among other live casino games. The house edge can fall somewhere between .05% and 1% in a game with a single deck of cards. 

Are Online Blackjack and Live Blackjack different?

At online casinos these days, you can play Blackjack online either against the machine or against a real live dealer. RNG or Virtual Blackjack is a digital game which involves no human interaction.

In this case, the cards are ‘dealt’ by a computer program, which works according to a Random Number Generator (RNG).

In Live Blackjack, the game rules remain the same, but the atmosphere is altered by the presence of a human dealer or the use of a virtual set-up.

Differences Between Live Dealer Online Blackjack and RNG (Virtual) Blackjack

Live dealer and RNG games are both exciting ways of playing Online Blackjack.

In Live Blackjack, a real croupier will be streamed onto your screen from a sleek casino setting, giving you a chance to interact with him or her as you play.

RNG blackjack games are presented as virtual affairs, with a computer-generated table and cards that you are randomly dealt.

In this case, it is the casino software that ensures total fairness and random results on every hand.

Which of these different approaches is the best way to play Online Blackjack, you ask? It really just comes down to your personal taste.

Virtual Online Blackjack Games

Many of the top game providers produce virtual blackjack games where the action is fast and exciting. These include Blackjack games by NetEnt and Blackjack Lucky Ladies by Felt.

These versions typically let you wager on various hands by sliding your chips onto the betting areas.

Each game provider has its own style, but many of the games take a similar approach, with a slick layout and easy controls.   

Studio Live (Dealer) Online Blackjack Games 

Live Blackjack takes place in a physical casino studio, using real Blackjack cards, and is streamed to players’ screens in real time. Evolution, Playtech and Pragmatic Play produce many of the best live Blackjack games for British players.

Once players place their bets, the dealer deals out the cards, and you can watch the action take place from multiple camera angles. This makes for a more genuine experience, giving you the feeling that you’re playing Blackjack at a brick-and-mortar casino!

A look at the online casino section of many casinos will reveal multiple variants of Live Blackjack online, such as Free Bet Blackjack and Blackjack VIP tables for high rollers.

The live dealer blackjack selection in British casinos has been growing in recent years, so you can expect more titles and variants to be added in the future.

How to Play Online Blackjack – Rules of Blackjack

Blackjack is played between a dealer and the players. All players play against the dealer and not against each other. The aim is to get a card total that doesn’t go over 21, but that is still higher than the dealer’s total. 

Each card is worth its own value, except for the Ace, which can either count as ‘1’ or ‘11’. The Queens, Jacks and Kings are all worth 10 each.

The game is played in these steps:

1. Each player places a bet.

2. The cards are dealt.

3. The dealer gives one card to each player in the upright position and one card in the upright position to himself. 

4. Another card in the upright position is then dealt to each player, but the dealer’s second card is kept in the downright position. Therefore, each player, except the dealer, receives two cards in the upright position. The dealer will have one card face up and the other one face down. 
5. If a player’s first two cards are an Ace and another 10-card, then he’s first-time lucky – this equates to exactly 21 and the player wins. If both dealer and player get 21, then this is called a tie and the player takes back the amount wagered.

Blackjack Rules and Bets – How to Play: For Beginners

The goal is to get closer to 21 than the dealer without going over this magic figure (going bust). You’re given two cards first of all and need to decide whether to ask for more or stick with those two.

During your turn, you’ll make decisions such as doubling your bet, ‘splitting’ your cards into two separate hands or taking ‘insurance’ against the dealer’s Blackjack hand (21).

Once you are finished, it is the dealer’s turn to turn over their cards. They need to follow set rules that determine whether they ask for another card or not.

The best hand in this card game is when you get a total of 21 on the first two cards, which will normally give you a higher payout and can’t be beaten. 

Otherwise, any hand that betters the dealer’s total without going over 21 will give you a win.

Blackjack options

Below are the options normally available to players before the dealer reveals his hole card:

• Stand (also known as stick or stay): the player decides not to take any more cards.
• Hit: the player draws another card. If this results in the player’s total points exceeding 21 (known as “bust”), then he loses the game.
• Double: the player doubles his bet and gets only one more card.
• Split: If a player’s first 2 cards are of the same value, then he may separate his cards into two individual hands and double the bet. The dealer will deal a second card to pair up with each card. Then, the player has to decide whether to hit, stand, or double normally, and can win or lose his bet separately for each one of these hands. 
• Surrender: if the game offers this option, the player can forfeit half his bet to the house and not play out his hand.

Blackjack Side Bets 

Side bets are additional bets a player can place during a Blackjack game. These bets generally have a lower RTP than the main game, meaning that it’s more difficult to make money from them.

Yet, the extra excitement that they add and the prospect of big returns if they come up mean that a lot of players are tempted to give them a go.

Blackjack Insurance 

Commonly offered in most online Blackjack games, this side bet pays out if the dealer gets a Blackjack hand (21) with their first two cards. While you’ll still lose the hand if this happens, you’ll also get a payout to soften the blow.

21+3

This blackjack side bet is based on your first two cards and the dealer’s face-up card making a strong poker hand.

The better this hand is the more you win, with a suited three of a kind usually the top prize.

Inspired from Poker, the 21+3 side bet involves betting on a number of scenarios involving the players’ and the dealer’s cards. These are:

• Flush – this involves betting on having 3 cards of the same suit (for instance 3 hearts), and has odds of 5/1, but also the lowest payout
• Straight – betting on a 3-card combination of the same sequence, for example 5, 6 and 7 (irrespective of the suit). This bet comes with odds of 10/1
• Three of a Kind – a bet that your first 2 cards and the dealer’s upcard will be of the same rank (for example, 3 Jacks or 3 fours). The odds of this happening are 30/1
• Straight Flush – this involves betting on having 3 cards in numerical order of identical suits, for example, 1 of diamonds, 2 of diamonds and 3 of diamonds. The odds for this are 40/1.
• Suited Three of a Kind – betting on getting 3 cards that are of the same suit and value, for example, 3 Queen of Hearts. This is the best paying Blackjack side bet, which comes with odds of 100/1.

Pair Bets

There are a few different possibilities here, as you could get different types of pair on your first couple of cards.

Mixed pairs and coloured pairs are good but it is a perfect pair of the same suit and value that pays out best of all.

This bet is placed before the round starts, and may consist of 3 bets, each of which involves getting a kind of pair:

• Perfect Pair – betting on getting the two same cards of the same suit (for example 2 of hearts and 2 of hearts). This is the highest paying perfect pairs bet, with odds of 30/1
• Coloured Pair – Betting on getting two cards of the same colour and value but a different suit (for example 2 of hearts and 2 of diamonds). The odds for this bet are 15/1.
• Mixed Pair – betting on getting a pair of different colours (for example 2 of hearts and 2 of spades). This bet comes with odds of 7/1 and is the lowest-paying Pairs side bet.

Bet Behind 

With this type of blackjack bet, you are wagering on another player’s hand rather than your own.

This means that you have no control over the decisions that are taken on it, but can profit if he wins!

The Number of Decks and the House Edge (Advantage)

The number of decks used in online blackjack games plays a big part in your chances of winning.

This is because there is more chance of getting a blackjack hand of 21 on your first two cards if fewer decks are used.

The reason for this is that more blackjack hands should be dealt, giving you a better chance of landing the higher payout it provides.

Most of the best blackjack online versions use eight decks, but some use fewer than this. You might even see a single deck that is shuffled after every hand.

We can see in the table below the effect that the number of decks has on the house edge, which is the advantage the casino has. 

A low house advantage means that you’ll be in with a better chance of picking up some winnings.

The house edge changes slightly depending on the number of decks used, the table’s specific blackjack rules and side bets.

Is there a Blackjack Strategy that actually works?

If you’d like to take full advantage of Blackjack’s low house edge, you’ve got to play Blackjack by sticking to the basic strategy.

This strategy will dictate whether you should hit, stand, split, surrender, or double down, depending on the total of your 2 cards and the dealer’s face-up card.

Basic Blackjack Strategy was created by a computer simulation based on combinations of millions of hands. In this way, people were able to conclude what are the best decisions to make with each hand, and this gave rise to the Blackjack chart above. 

There are additional Blackjack rules which will tell you when to surrender, double down and when to split pairs in Blackjack, should the game you’re playing allow for these moves.

It can be difficult to remember what you should decide in each situation as you play Blackjack, which is why a Blackjack chart can be so helpful for beginners. This chart will show you what you should do depending on your hand and the dealer’s card.

H = Hit; S = Stand; D-H = Double if possible, otherwise Hit; D-S = Double if possible, otherwise Stand

When to Surrender 

The option to surrender is sometimes offered when you play blackjack online.

It is typically seen in versions that have “surrender” in the name. These games allow you to quit early and get part of your stake back.

This is often worth doing when the dealer has an ace or 10 and you have a poor hand such as a hard 12 to 17 with no ace in it. 

You might win in this situation, but it is more likely that you lose.  

When to Consider Pair Splitting

‘Splitting’ with a pair of identical cards doubles your bet and will give you two chances of winning.

It is generally recommended that you split aces to get two strong hands while splitting a pair of 8s breaks up one of the poorest Blackjack hands.

In other cases, it comes down to what card the dealer is showing. The only cards that you will probably always want to avoid ‘splitting’ are 10s, 4s and 5s.

When to Double Down

Doubling down is one of the most interesting and aggressive moves you’ll make when you play blackjack online.

You’re doubling your bet in exchange for getting just one more card. You’ll want to do this when you have better cards than the dealer’s face-up card and can’t go bust with any other card you might get.

Among the hands where this strategy makes sense are a hard 9, 10 or 11, as well as a soft 16, 17 or 18.

Generally, you want to see a card valued between 2 and 6 in the dealer’s hand too.

Online Blackjack Card Counting

Card counting is a strategy that may be employed at brick and mortar casinos while playing Blackjack. This involves keeping track of cards to determine whether the next hand is likely to favour you not.

In Blackjack, the player is more likely to win if there are more Aces, 10s, Jacks, Kings and Queens left in the shoe, and therefore card counting is used to try and determine this. To employ this strategy, the card counter assigns a positive, negative, or zero value to each possible card.

Then, whenever a card of that value is dealt, the count is adjusted accordingly to try and keep track.

Casinos will do their best to prevent you from Blackjack card counting, and may even force you to stop playing if you’re caught!

What’s more, Online Blackjack Card Counting is next to impossible, as decks are automatically shuffled after every round or cut down the middle.
