I think casinos use various types of dealing devices, including automatic shufflers and continuous shuffling machines (CSMs), but the prevalence of CSMs may vary across different casinos and games. Some players may prefer games without CSMs, as they perceive them to be less advantageous to players who count cards in blackjack, for example. Ultimately, the casino industry operates based on supply and demand, and it is up to individual casinos and players to decide how they want to conduct their gambling affairs.
