The History of Blackjack

Blackjack is the most widely played casino banking game in the world today but you might be surprised to find out that it dates back a few hundred years. That said, it’s pretty difficult to pin down the exact origins of blackjack. Some historians believe that the Romans should be credited with inventing the concept as it is close to a game they played using wooden blocks of different numerical values.

Most historians point to the game of twenty-one being mentioned in a book by the Spanish author of Don Quixote, Miguel de Cervantes as the first recorded reference to Blackjack. In the book, written in 1602, a couple of card cheats working in Seville play Veintiuna, Spanish for twenty-one. They state that the object of the game is to reach 21 points without going over and that the ace values 1 or 11.

The game of 21 continued to grow in popularity across Europe and was first exported to North America by the early the French settlers. In America blackjack featured a bonus payout if a player's hand contained the ace of spades and either the jack of clubs or the jack of spades, this hand was called a blackjack. The bonus has long since disappeared but the name stuck.

As the game continues to evolve in the 21st century, it’s found a whole new fanbase with the emergence of online casinos. Look no further than the wide variety of blackjack online versions you can enjoy at William Hill online casino today.

The Most Popular Versions of Online Blackjack

Despite being around for hundreds of years, blackjack is as popular today as it has ever been. The game has reached a whole new audience thanks to online casinos like William Hill offering several new and innovative versions of this classic table game. Here is a rundown of the most popular versions of both online video blackjack and live blackjack right now:

Classic Blackjack

The most popular of all online blackjack games is the classic version and makes the ideal choice for players who like to keep things simple. It’s played with between 1 and 8 decks of cards and is a straight race to get as close to 21 as possible between players and the dealer.

European Blackjack

This version differs slightly from classic blackjack but only in the way the cards are dealt. One face-up card is dealt to the dealer but they do not deal a second card to themselves until the player has decided on their next move.


This is ideal for players looking for a fun twist to the traditional blackjack game. It’s played much like Spanish 21 with all the 10 point cards being removed from the decks. Pontoon, Twist and Stick are called instead of the usual Blackjack, Hit and Stand.

Experience Live Blackjack at William Hill

There’s nothing quite like pulling up a stool alongside other blackjack fans and experiencing the thrill of going head to head with the dealer at a casino. Thanks to the latest streaming technology you can now enjoy playing blackjack in real-time at our live casino.

The high definition streams at William Hill will bring you right into the blackjack action to create a fully immersive casino experience.

You’ll find several variations of this popular table game to enjoy in real-time, including:

Live Blackjack

If you enjoy this classic card game without the extra features that some versions offer then live blackjack is the one for you.

Live Unlimited Blackjack

Unlimited Blackjack does exactly what the name suggests, it lets an unlimited amount of players sit at a single table. All bets from players count which can lead to a very interesting game with every deal.

Royale Blackjack

This version offers a royal twist on the original by allowing you to place ‘Queen’ and ‘King’ side bets in the game. Tap on the ‘K’ or ‘Q’ circles to either side of the main betting areas to place your regal bets.

How to Play Online Blackjack at William Hill

Blackjack rules state that one or more standard 52-card decks are used to play blackjack. The cards 2 to 10 are worth their face value with the kings, queens, and jacks each worth 10. Aces can be used as either 1 or 11.

The main objective is to beat the dealer by drawing cards totalling closer to 21 than they do without going over that total. Having a total above 21 is called going bust. The best total in the game is having a total of 21 with just 2 cards, known as a blackjack.

Here are the steps for how to play blackjack at William Hill online casino:

Step 1 - Find the blackjack game you want to play. If it’s in our live casino section, click ‘take a seat’ to join the game.

Step 2 - Choose how much you want to bet. Available bets vary between game types but can start from less than €1. All the betting options will be shown on the table. Click the bets that you’d like to place.

Step 3 - Once you’ve finished betting click the ‘deal’ button and you will get 2 cards dealt to you face up. The dealer will also take 2 cards with just one facing up.

Step 4 - You’ll now get the option to Hit, Stand or Double Down. Players with a pair will also have the option to Split.

Step 5 - After you’ve made a choice more cards will be dealt to see if you or the dealer goes bust i.e., exceeds a total score of 21.

Step 6 - Depending on the outcome of the hand, you’ll either be credited with your winnings or have your bet taken. Many online blackjack games have a re-bet option if you wish to wager the same amount on the next hand.

Blackjack Odds Explained

With most casino games the house always has the edge and the same can be said for pretty much all forms of blackjack. However, there are a few advantages that players have on their side which are good to know about before you start getting dealt any cards.

Understanding the probability of going bust is one of the fundamentals of becoming a successful blackjack player. Depending on the card you have in front of you, there is a sliding scale of how likely it is that your next card will make you go bust.

For example, if you have 11 or lower in your hand there is a 0% probability of going bust. If you have 20 in your hand, it’s a 92% probability that the next card is going to shoot you over a total of 21. All the other hand values are somewhere in between and can help you to calculate your next move in the game.

Additionally, as an extra boost, anytime a player hits 21, i.e., gets a blackjack, they will be paid an additional amount. Being dealt a blackjack pays 3:2 which works out at 2.5 times their stake as long as the dealer doesn’t also have 21 in their hand.

Formulate Your Blackjack Strategy

Before you jump in and pull up a stool at one of the William Hill live casino tables it’s a great idea to brush up on the blackjack basic strategy which tells you what action to take, based on the cards that have been dealt. In addition, as with many popular casino games, there’s a whole lot of information out there on the best ways to beat the house using the blackjack rules and blackjack tips to win.

For beginners, a great blackjack strategy to your first few games is to take it easy and use a reasonably conservative approach. The main idea is to raise your bet a little every time you win and go back to your base bet every time you lose. This picks up on the little winning and losing streaks that often appear over a few rounds and helps you to keep your playing budget in check.
