Casinos shuffle decks in Blackjack using a variety of methods to ensure fairness and prevent card counting. In traditional games, dealers manually shuffle multiple decks by performing riffle and overhand shuffles, sometimes allowing players to cut the deck. To speed up the process and increase randomness, many casinos use automatic shuffling machines, which shuffle several decks at once and prepare the cards for the next round quickly. Some casinos also use continuous shuffling machines (CSMs), which continuously shuffle cards during play, making it more difficult for players to track card sequences. In high-security settings, the cards may be shuffled after every hand to maintain fairness and integrity. These methods help prevent manipulation and ensure the game remains unpredictable for all players.
 
Casinos employ a variety of shuffling methods in Blackjack games to ensure fairness and prevent players from gaining an advantage through card counting. Here are some common shuffling techniques used in casinos:

1. Manual Shuffling: In traditional Blackjack games, dealers manually shuffle multiple decks of cards. They usually perform a combination of riffle shuffles, where cards are divided into two portions and interleaved together, and overhand shuffles, where cards are shuffled by sliding them from one hand to the other. Some casinos also allow players to cut the deck after shuffling to add another layer of randomness.

2. Automatic Shuffling Machines: To streamline the shuffling process and increase the randomness of the cards, many casinos use automatic shuffling machines. These machines can quickly shuffle several decks at once and prepare the cards for the next round, reducing the time between hands and minimizing the chance of manipulation.

3. Continuous Shuffling Machines (CSMs): Some casinos utilize continuous shuffling machines (CSMs) in Blackjack games. These machines continuously shuffle the cards during gameplay, effectively resetting the deck after each hand. By constantly shuffling the cards, CSMs make it harder for players to track card sequences and gain an edge through card counting.

4. Regular Shuffling Intervals: In high-security casino settings, cards may be shuffled more frequently to maintain fairness and integrity. Some casinos shuffle the cards after every hand or after a set number of rounds to ensure that the game remains unpredictable and prevents any potential cheating or manipulation.

Overall, these shuffling methods are designed to uphold the integrity of the game and provide all players with an equal opportunity to win. By using various shuffling techniques, casinos can prevent players from gaining an unfair advantage and ensure that Blackjack games are conducted in a fair and transparent manner.
