Blackjack history - online blackjack America

The game of Blackjack has many influences from around the world. Some of these include Quinze, One-and-Thirty, Trente-et-Quatre, Seven-and-a-Half and Baccarat. Each of these games required the player to reach a certain number. The one theory most players agree on is that it originated in the 1700’s in France with the game Vingt-Un which literally translates to 21. In the late 1800’s the game made its way to America and the first recorded game of Blackjack was in a gambling hall in Indiana around 1910.The games popularity grew when gambling halls offered a large payout to the player whose hand was an Ace and a Jack. This lucky hand became known as the ‘Blackjack’ hand and thus the name was born. The game was legalized in the state of Nevada in 1931, which led to the rise of the game online in the 1990’s.

Online Blackjack, also known as 21 or pontoon is a simple game that requires a mix of luck, strategy and concentration. To better understand the game let’s take a look at how the game works. The aim of Blackjack is to get as close to 21 as possible, before the dealer does. The dealer hands out two cards to each player, including him/herself. One of the dealer’s cards, known as the ‘up’ card, is placed face up, and the other, known as the ‘hole’ card, is placed face down. The game then moves in a clockwise direction beginning with the player on the dealers left. Once each player has accessed their own cards and has looked at the dealer’s ‘up’ card, each player makes a decision to:

  • Stand-this means that you are happy with your current cards and choose not to take anymore
  • Hit-this means that you would like more cards (players can hit until they reach a desired value or go ‘bust’ which means to go over 21)
  • Double down-this action is used if you feel very confident about your hand as it doubles your bet, and allows you to take one more card only
  • Surrender-this action is used if you feel you have a losing hand and results in losing half the amount you bet, this action can only be played on your first two cards and not after you ‘hit’
  • Split-this action can be used to split two cards of the same value, forming another hand, which doubles your bet

The rules are simple and easy to follow, try to memorise them to improve your game:

  • The aim of the game is to get as close as possible to 21, using the value of the cards in your hand, and if need be, the cards you get from choosing to hit.
  • The game is over when the player or the dealer busts or surrenders.
  • If neither the dealer nor the player busts or surrenders, the person with the highest valued hand wins.
  • The numbered cards keep their value
  • The King, Queen and Jack are each valued at 10.
  • The value of the Ace can be chosen by the player, and can either be valued at 1 or 11.
  • A pair of cards made up of an Ace and 10 is known as Blackjack.

  • Always remember that the goal of Blackjack is not to get to 21 but to beat the dealer.
  • Set a bankroll limit and stay within it.
  • Never play Blackjack when you are intoxicated as it will limit your ability to concentrate and make decisions.
  • Always take the dealers ‘up’ card into consideration before making any decisions.
  • A general rule of strategy is to always hit on a hard eight or less.
  • Always split aces and two 8’s.
  • Stand on 18 if you do not want to double down
  • Stand on a 17 if the dealer’s ‘up’ card shows seven or less
  • Hit if your hand is between 12 and 16, and the dealers is seven or higher

Online Blackjack FAQ

What happens when a dealer ‘draws out?’

When a dealer wins based on a hand that is likely to bust. For example, if the dealer has 16 and hits, and gets 5 to make 21, it is known as a ‘draw out.’

What should I do if I feel like I am being cheated?

If you feel like the online dealer has cheated you the first thing you should do is try to take a screen shot of the game as proof that you have been cheated. Some online casinos allow you to replay the last hand, which will allow you to take a screen shot then. You could then call the help centre and explain what happened. A screen shot or some form of proof is important as then it cannot be denied and most online casinos require proof before they can consider the next step.

Why should I not split my tens?

There is no set rule that says you cannot split tens. It is just frowned on because two tens give you an almost unbeatable total of 20, which is a really good hand to stand on.
