There is no one answer to this question as it depends on a number of factors, such as the type of online blackjack game you’re playing, the kind of card counting software you’re using, and the skill level of your opponents. That said, in general it’s generally agreed that card counting does not work reliably in online blackjack.
There are a number of reasons for this. First and foremost, the game is played against artificial intelligence (AI) rather than live players, which makes it much more difficult to determine your own personal odds and make optimal plays based on those odds.
Additionally, modern online blackjack games generally feature very tight rules that punish players who deviate from the standard play pattern – making card counting an even more difficult task.
In conclusion, while card counting may have worked in the past against live players in traditional blackjack casinos, it is not likely to be successful in today’s online casino environments – where the game is much more complex and opponents are typically much better AI-based players.
