There is no definitive answer to this question, as cheating in blackjack is difficult to track and prove. However, there are several theories about how dealers might cheat, and evidence that suggests some dealers do cheat.
One theory suggests that dealers might collude to draw cards that will benefit them financially. For example, a dealer might deliberately choose to show a low card, in order to increase the chances of getting a higher payout from the player.
Alternatively, the dealer might let another player hit the jackpot while he or she collects cards that will not increase the player’s chances of winning.
Another theory suggests that dealers might alter the results of random number generators (RNGs), which are used to generate cards. This is possible because RNGs are relatively simple machines that are susceptible to manipulation.
For example, a dealer could insert a piece of metal into the machine in order to change its output. Alternatively, the dealer could tamper with cards before they’re dealt, in order to produce different results.
Despite these theories, there is no concrete evidence that dealers cheat in blackjack. It’s possible that some dealers do cheat, but it’s also possible that this isn’t happening very often or at all.
Ultimately, it’s impossible to know for sure whether or not dealers cheat in blackjack.
