A machine that shuffles cards continuously to prevent card counting in table games. CSMs continuously shuffle cards, intermixing them after each hand, which distinguishes them from traditional shuffling done by dealers or automatic shuffling machines that shuffle an entire pack in a single operation.
CSMs automate card shuffling after every hand, eliminating pauses for manual shuffling. The dealer inserts played cards into the CSM, which intermixes them with multiple decks inside the machine. CSMs use card recognition technology with optical sensors to identify each card’s value and suit as it enters. A software algorithm determines a random placement for the card, and mechanical controls move each card to its randomised location within the machine. The system maintains a count of the remaining cards, and dispenses refreshed hands as needed.
CSMs thoroughly randomise cards, so cards already used in the game have the chance to appear in subsequent hands. Every time a dealer pulls a card from a CSM, they are drawing from a group of cards that have been continuously shuffled, ensuring fair and unpredictable gameplay.
Casinos use CSMs to speed up gameplay and prevent card counting. The first CSMs emerged in the early 1990s, and by 2020, over 80% of blackjack tables in Las Vegas utilised CSM technology. The Shuffle Master company presented its first shuffling machines for blackjack in 2000. These machines ensure a randomised shuffle of all cards, enhancing game integrity.
