Card counting is a very popular blackjack strategy that has a high place in blackjack culture. It is a mark of a pro player and one of the most prized skills in the game. While basic strategy will drop the house edge to 0.5%, when combined with card counting, players can actually tip the odds in their favor.
But there is bad news for online blackjack players: card counting does not work in online blackjack.
Sorry, everyone, but it just does not. This can be owed to how the game of online blackjack actually functions. While the rules of a game of online blackjack do not differ from the rules found in a basic game of blackjack in a brick and mortar casino. The difference lies in how the game itself is actually conducted.
A live game of blackjack in a brick and mortar casino will be dealt by a dealer from a deck that is played almost entirely through with cards being discarded after they are played. Unless you are playing at a table with a CSM, which you should not be in the first place, but that is another story. The point here is that cards are discarded from play once they have been played.
In online blackjack, the Random Number Generator (RNG) will pull from all possibilities when dealing a new round and hitting hands. And when I say all possibilities I mean it. This has the effect that no cards are discarded.
And since card counting depends on cards being discarded from play it is fairly useless in online blackjack simply because of the RNG, which is necessary for a game of online blackjack to actually function. So the best piece of strategy that an online blackjack player has in their corner is basic strategy.
