Blackjack is in fact a very simple game but an online casino such as the brand new Paddy Power casino there are several variations which can help to keep the game interesting; in fact Paddy Power casino has no less than 10 variations of blackjack and we shall explain a few here at casinos.ie for you. Firstly there is surrender blackjack which is played in the normal way but you have the chance to surrender your hand after you have seen your first two cards so if you consider them poor and not worth playing you can get out with the loss of only half your ante. A more complicated blackjack variation is what is called 21 Duel Blackjack in which you are dealt two cards and the dealer is dealt two cards but there are also two community cards for both you and the dealer to use; these two cards are face up. Your initial two cards in Duel Blackjack are one face up and one face down and you play with the face up card; you then elect one of the two blackjack community cards to play with your face up card and then either hit or stand (you still have to beat the dealer by getting as close to 21 as possible without busting). If you decide to hit, your second card will be turned over and play proceeds from there. There are some unique rules about the dealer’s hand not qualifying and your bet is automatically doubled when you select one of the community cards so read the duel blackjack rules before playing and as free blackjack is readily available for this game we recommend you try it out first. A third blackjack option at the online casino is Switch blackjack where you are playing two hands and you are able to switch the top cards of each hand with each other if this gives you a better chance of winning. As this will generally give you an advantage the downside is that should the dealer reach 22 then the hand is a push. These are interesting blackjack variations and well worth a look at the new Paddy Power online casino..
