a cutting-out step of cutting out the playing cards constituting the deck and the card on which no pair of suit and rank is printed from the base sheet;
a shuffling step of removing the card on which no pair of suit and rank is printed and shuffling the playing cards constituting the deck together with additional playing cards constituting one or more other decks to obtain the playing card set, wherein the additional playing cards are printed on and cut out from either the same base sheet as the deck or a different base sheet;
an ID assigning step of assigning to the playing card set a playing card set ID different from other playing card sets; and
a database producing step of storing the playing card set ID and the sheet ID by associating the playing card set ID and the sheet ID with each other in database.
