Online casino blackjack is one of the more simple casino games available at all online casinos although some do try to make it more difficult by offering different versions such as Switch Blackjack but as you might expect, these variations are not all that they might seem so make sure that you understand the up side and the down side before playing. The simple game of blackjack is not to get as close to 21 without busting as some would have you believe but rather to have a better hand than the dealer. Some online casinos are at pains to point this out but most are not preferring that you ignore the fact that one of the dealers cards is exposed which could encourage you to try for a higher number and end up bust. A good blackjack player at an online casino will realise that you can win on any number if the dealer goes bust and as the blackjack dealer has no choice but to draw cards up to 17 there is a good possibility that this will happen but if you have already bust then you have lost regardless of what happens to the dealer. In online casino blackjack the weak cards are a 6 or a 5 as there are a number of cards that together with that will place the dealer in a position where a third card could bust them and if you are holding 15 or 16 in your hand it may be better to stand in the hope that the dealer will bust rather than risk a draw which would bust you. These are the things that a good online casino blackjack player will look for to increase their winning chances but of course at the end of the day it all comes down to luck.
