Blackjack could be one of the oldest casino games around at online casinos having been played in various forms such as Pontoon or Vingt et un for many years. The current online casino game of blackjack is however slightly different from Pontoon and is basically the American version whereby in a push your stake is returned. Online blackjack is about as simple as a card game can be although there are some things you can pay attention to in order to increase your chances of coming out ahead. The first thing to consider when playing blackjack online is what you are trying to achieve and many Irish casino players will tell you that the objective is to get as close to 21 as possible without going over 21 which is called busting. Casinos.ie has a slightly different take on this believing that the objective of online blackjack is to beat the dealer. This might sound rather elementary but in fact it can change the way in which you play blackjack because you can beat the dealer with any number as long as the dealer busts which will happen as they are obliged to draw a card on anything under 17. With this thought in your armoury you must assess the chances of the dealer busting but all you have to go on is the exposed card of the dealer. Online casino blackjack is a simple game and the only advantage that the dealer has is that you as the player plays first and if you bust then you lose regardless of what might happen with the dealer so if you can avoid busting your winning chances are improved. It is not being suggested that you avoid busting at all costs as you would otherwise be sticking on 12 but by assessing the chances and risk online casino blackjack can be a profitable casino game.
