In Blackjack, casinos shuffle decks using a combination of manual and machine methods to ensure fairness, prevent cheating, and maintain the integrity of the game. Dealers may manually shuffle the cards, especially with fewer decks, by splitting and mixing the piles, often followed by a "cut" performed by a player. For games with multiple decks, automatic shuffling machines are used to shuffle quickly and efficiently, reducing human error. Some casinos also use continuous shuffling machines that keep the cards in constant rotation, making it harder for players to track or count cards. Overall, these methods are designed to ensure randomness and security, making it difficult for players to gain an unfair advantage.
 
In Blackjack games, casinos implement various shuffling techniques to maintain fairness and prevent any form of cheating. The manual shuffling method involves dealers shuffling the cards by hand, primarily used in games with fewer decks. This method typically includes the dealer splitting the deck into several piles and then thoroughly mixing them together. To add an extra layer of randomness, a player often performs a "cut," where a portion of the deck is placed on top of the other part to initiate a new shuffle sequence.

For games that involve multiple decks, automatic shuffling machines are commonly employed to shuffle the cards swiftly and accurately. These machines help minimize human error and ensure a more thorough mix of the cards. Additionally, some casinos utilize continuous shuffling machines (CSMs) which shuffle the cards continuously throughout the game. CSMs are designed to prevent card counting and tracking by players, as the cards are immediately returned to the shuffler after each round, resulting in a constant shuffling process.

By employing a combination of manual shuffling, automatic shuffling machines, and CSMs, casinos aim to uphold the integrity of the game and prevent any advantage that could be gained through card manipulation or tracking. These shuffling methods are crucial in maintaining the randomness of card distribution, ultimately providing a fair and secure gaming environment for all players.
