What is Continuous Shuffling Machine?
The CSM does as it says on the tin: continuously shuffles the cards in a deck so that card counting is not physically possible.
Continuous Shuffling Machine Explained
The concept of the CSM came about because of the growing wave of illegal card counters who now frequent some of the largest and most reputable casinos in the world. A card counter is someone who keeps track of the cards dealt in blackjack, so that they know when to bet large amounts, when not to, when to leave the table, or when to alert other people to the table (if playing as part of a team).
Because the person who counts cards knows what is likely to be drawn next, they can adjust their bets accordingly and are often successful, winning hundreds if not thousands through their illegal methods.
However, the CSM serves to combat this. The machine works as follows: once a hand is completed, the cards that have just been used are replaced into the CSM and mixed with the other cards still in the shoe. A common mechanism by which the typical CSM works is that it uses an elevator to shuffle the cards randomly. This moves up and down while the cards are placed randomly onto any of the shelves within the device. Then, when the shuffle is complete, the CSM automatically selects a random shelf of cards to transfer to the shoe. Therefore, every card already used has every probability of inclusion in every shoe, so card counting is futile.
The CSM also means that the dealer needn’t shuffle the cards at the end of the hand, saving time and effort at the same time as mitigating dishonest opportunities for cheating card counters.
