Brief History of Blackjack

The exact origin of blackjack is not clear despite its long history. But one of the earliest mentions is in a book by the Spanish author Miguel de Cervantes from the early 17th century. Records of this casino game would later emerge in France during the 18th century. Then records appeared also in Britain and the U.S. in the 19th century. 

At first, the game was called 21 since the aim is to reach a hand with that value. Later on casinos introduced bonus payouts if a player drew an ace of spades. Additionally, the bonus applied to either a jack of clubs or spades. Hence the name of the game later became blackjack. Although these bonuses no longer exist blackjack remained with the same name.

How to Play Blackjack

The main objective in blackjack is to beat the dealer by achieving a hand value closer or equal to 21. Hence the player with the hand closest in value to 21 wins the betting round. However, reaching a value over 21 counts as a loss.

The game begins when the dealer issues 2 cards to players around the table, facing up. Then the dealer gives 2 cards to themselves – one face up and the other face down. Next, the players place their bets around the betting circle. Of course, this is done using chips and the bet depends on the value of the hand. This value is not affected by the suit, and the cards are valued as such:

  • Cards 2 to 9 are counted at their face value.
  • Face cards all have a value of 10.
  • An ace can be worth 1 or 11 points, depending on the hand. 

Variations of Blackjack

Almost certainly all casinos out there offer blackjack. Of course, each casino has its own variation that they offer. Hence there are more than 20 blackjack options available out there. Out of those, there are 5 which are the most common.

Blackjack Switch

Every player initially receives 2 hands and 4 cards in total. Additionally, there’s the option to switch the 2nd card in each hand. Hence, this variant allows players more flexibility. However, the casino will often make up for it. For example, if the dealer draws 22, this is not a bust but rather a push.

Chinese Blackjack

This variant’s main difference is that the position of the dealer is rotated. As a result, it is more of a regional game and can’t be found in most casinos. Also it allows players to draw special hands, such as Ban-luck (blackjack) where the player receives a 2 to 1 payout and not 3 to 2.

Double Attack

In standard blackjack, you should place all bets before the dealer reveals the up card. However, double attack allows a player to double their bet after the dealer does so. Furthermore, the game involves a 48-card deck with the 10s removed. The rules remain the same as the standard variation.

Double Exposure

Double exposure is another very popular blackjack variant. Here both of the dealer’s cards are exposed, giving players a huge advantage. In order to counter this, the dealer will win all ties. Additionally, a blackjack will only pay even money (1 to 1) and not 3 to 2.

Spanish 21

The name of this variant comes from the reference to a Spanish deck of 48 cards with the 10s removed. Because this reduces a player’s edge, the game allows players to double down after splitting. Additionally, there’s an option for a subsequent re-splitting in case of aces. Plus, the player wins all draws including a blackjack.

What Is House Edge?

A standard variation of blackjack presents a house edge of below 0.50% if you play with a basic strategy. However, the exact house edge depends on the variation of blackjack and its specific characteristics.

For instance, the number of decks in use determines how often they are reshuffled. Naturally, the more reshuffling takes place, the higher the house edge. Moreover, casino rules can either raise or reduce the house edge. So of course you should seek tables with player-friendly rules.

Strategies for the Blackjack Table

The most effective strategy is called ‘basic’ because it involves simple logic. For example, you wouldn’t ‘hit’ if your hand total was 20 points or ‘stand’ if your total was 10. However, for new players, we recommend a conservative strategy instead. It involves starting with the table minimum. In order to avoid losing too much money, you should thereafter only increase your bet after several consecutive wins. 

Blackjack strategy charts show you the right moves to make according to basic strategy. The basic strategy for blackjack is the best play that you can choose when you consider what the dealer is showing and the hand you have. When it was discovered in the 1950s, it changed blackjack and how people thought about the game, inspiring other blackjack enthusiasts and also leading the founding of card counting.

The best way to reduce the house’s edge against you is by sticking to the optimal play for both hands. Basically, the average player is expected to give something between 3% to 5%, or even more, while a player using a basic blackjack strategy can give up less than 0.5%. This basically means that you are increasing your chances of winning provided the cards go right.

Blackjack online basic rules to remember

  • If the dealer shows a 7, 8, 9, 10, or Ace, hit up to 17 or more
  • Hit if the dealer shows 9, 10, or Ace and if you have a 7 or less and Ace
  • Hit if the dealer shows 7 or more and you have a 6 or Ace
  • If the dealer shows a 4, 5, or 6, stand at 12
  • If the dealer shows any number less than 7, stand at 13
  • Split eights and Aces
  • Split 9 except if the dealer shows a 7, Ace or 10
  • Split 7 except if the dealer shows an 8 or more
  • Split 6 except if the dealer shows a 7 or more
  • Don’t split 5
  • Split 4 whenever the dealer shows a 5 or 6
  • Double if you have 11
  • Double expect when the dealer shows a 10 or Ace
  • Double 9 except when the dealer shows a number more than 6
  • Double 7 or 6 and Aces except when the dealer shows a number more than 6
  • Double 5 or 4 and Ace if the dealer shows a 4, 5 or 6
  • Double 3 or 2 and Ace if the dealer shows a 5 or 6
  • Surrender a hard 16, but not 8-8 vs. an Ace, 9, or 10
  • Surrender a hard 15 vs. 10, Ace

You should also remember that although the basic strategy is proven mathematically, there will always be exceptions to the rules, which are usually based on the number of players, conditions, and number of decks used by the dealer.

Blackjack doesn’t end at the basic strategy. There are many other recommended advanced strategies that you can use to improve your chances of winning. In case you want to take more risks, the Martingale system involves doubling your bet every time you lose. But when you win, you will get to recover all previous losses. However, these can increase rapidly, and hence you need a higher bankroll.

Other blackjack strategies

Don’t take insurance or even money

This is basically the first strategy you should keep in mind. For instance, if an Ace is the dealer’s up card don’t take insurance and carry on with the round as usual.

View your hand as hard total if you are unable to split the cards

Another key strategy is that if you are playing a hand and the chart for the basic strategy tells you to split cards and you are not able owing to the re-splitting limitation, you will need to view your hand as a hard total and continue to play based on the rules. For instance, if you’ve been dealt two 3’s and you cannot split the cards, you will need to view both hands as a 6. In this case, based on the rules of the basic strategy chart, if the dealer’s up card is a 2, you should hit.

The reality is that blackjack is a probability game and if the basic strategy is used accurately, you are likely to win. It doesn’t really matter whether you are a new player or a seasoned pro, blackjack strategy is the right guide to increase your chances of winning.

Blackjack on Your Mobile

Free play is a good way to learn the game rules, too. However, with free mode you can never really win actual cash.

Give it a try and you’ll see for yourself how much more fun it is.
