What is Counting Cards and Why is it Illegal?
Card counting is a strategy commonly associated with blackjack, where players attempt to track the ratio of high to low-value cards dealt from the deck. The goal is to predict the likelihood of certain cards appearing, giving the player a statistical edge over the house. This practice has raised the question: why is counting cards illegal in casinos, or is it even illegal at all?
