In blackjack, riffle and restack is a shuffle technique where the dealer divides the deck into two roughly equal piles and then interleaves the cards from both piles, merging them into a single deck. This is known as the riffle. Once the riffle is complete, the dealer then takes the new deck and separates it into two piles again, one card at a time, from the top of the deck. This is known as the restack. The process can be repeated multiple times to further randomize the deck. Riffle and restack is one of several common shuffle techniques used in blackjack to help prevent card counting and other forms of cheating.
