The casino gambling game of blackjack is also one of the most popular games in the online casinos and many of us will have probably played at home at some time although it was probably better known as Pontoon or 21 but actually these have slightly different rules which it is worth knowing if your online casino offers them. For example in pontoon when the player and dealer have equal hands the player loses whereas in blackjack it is a push. Although the classic casino gambling game of blackjack is played at all online casinos as well as at the live casino options the casinos are always trying to keep it more interesting so there are quite a number of variations for gambling on blackjack available at online casinos so it is worth investigating if you are a blackjack fan. One of those blackjack gambling variations that we have found is duel blackjack which is sort of cross between poker and blackjack in that there are two community cards dealt as well as the two hands which can be used by the player or the dealer but it does take a bit of getting used to. A simpler blackjack gambling variation that you may come across in your online casino is blackjack switch and in this casino gambling game you are playing two blackjack hands but you have the option of switching the two top cards from each hand with other which may improve at least one and possibly both of your hands. As you can imagine however the online casino is not going to give this advantage without some form of penalty so a blackjack which becomes much more frequent will only pay at evens instead of the more normal 3 to 2 and should the blackjack dealer have a count of 22 it is a push instead of the normal bust. All of these little blackjack gambling variations can make it more interesting but we still prefer the original game.
