There is no single answer to this question as casinos cheat in different ways, but there are some general methods that are used more often than others.
One common method is called hot counting. This involves the casino personnel counting cards as they are being dealt, and then keeping track of how many high cards ( Ace through Ten) are being drawn.
If the number of high cards is significantly different from the expected count, this is a sign that the casino is cheating.
Another common method used to cheat at blackjack is called shoe cashing. This involves the dealer removing certain cards from the deck and replacing them with other cards, in order to give the player a better chance of winning.
This practice is illegal in most jurisdictions, but it continues to be a problem because players are often not aware that it is happening.
In conclusion, casinos cheat by using various methods to improve their chances of winning. It is important to be aware of these practices so that you can play blackjack ethically and win fairly.
