Card washing is a formalized manual procedure utilized by licensed casino personnel to ensure the integrity of the randomization process during the shuffling of playing cards. The technique involves distributing the card set face-down across the gaming surface and executing a bilateral mixing motion to disrupt any established sequences or inconsistencies from prior hands. Within the framework of standard poker operations, this procedure is mandatory at the conclusion of each round preceding traditional shuffling techniques. In high-stakes games such as blackjack and baccarat, the regulatory application of card washing occurs specifically during the introduction of new decks or the replacement of legacy sets to maintain strict compliance with fair play standards and operational transparency.
