Shuffle tracking is an advanced form of card counting in which a player follows clumps of high or low cards through the dealer’s shuffle. Rather than only tallying cards as they are dealt, the tracker estimates where those clumps will end up in the next shoe and raises bets when a favourable section is due.
The technique belongs mainly to six- and eight-deck blackjack. Dealers must follow a shuffle procedure set by the house, and the simpler and more predictable that procedure is, the easier tracking becomes, although it remains extremely hard to master. Like other forms of counting, shuffle tracking is not illegal: it relies on observation, not devices. Casinos still dislike it intensely, and a player suspected of tracking can expect to be asked to leave.
Shuffle tracking and live dealer tables
Because live studios deal from physical shoes, their shuffle routine, cut-card position and reshuffle frequency decide whether tracking is even possible. Shuffling machines and frequent full reshuffles remove the opportunity. RNG blackjack reshuffles its virtual decks every round, so it is immune by design.
