Abstract

A shuffling system includes multiple shuffling devices which are connected in series to one another, and multiple CPUs which are independent from one another, and are connected with the respective multiple shuffling devices, in which each of the multiple CPUs is used to shuffle the cards across the multiple shuffling devices, so that the cards are arranged randomly, and further, even if the information about the shuffle in each shuffling device is stolen due to an unauthorized access to the multiple CPUs, or the like, it becomes difficult to identify shuffled cards to which the stolen information is allocated in all the shuffling devices, and therefore the possibility that the arrangement of the shuffled cards is recognized is reduced.
