1. A shuffling system for obtaining a shuffled playing card set by performing a shuffle of a playing card set multiple times, the playing card set being made up of a predetermined number of decks, the shuffling system comprising:
multiple independent shuffling devices, wherein each of the multiple independent shuffling devices is configured to sort playing cards included in the playing card set one by one to perform the shuffle of the playing card set;
multiple independent sequencers or controllers, each sequencer or controller of the multiple independent sequencers or controllers corresponding to a shuffling device of the multiple shuffling devices and controls operation of the corresponding shuffling device of the multiple independent shuffling devices; and
multiple processors configured to control the multiple independent sequencers or controllers,
wherein each of the multiple processors has a random generator which generates a set of random numerical values,
each of the multiple independent sequencers or controllers controls the operation of the corresponding shuffling device to sort the playing cards included in the playing card set one by one in a random order using the set of random numerical values generated by the random generator of at least one of the multiple processors, and
the shuffling system performs the shuffle of the playing card set multiple times by each of the multiple independent shuffling devices performing the shuffle so that the playing cards in the playing card set are arranged randomly.
