Two card decks A and B are allocated to and shared by a dealer and each of “main players 1 to 5”. Two cards to be dealt respectively to the dealer and each of the main players are determined from the two card decks A and B. On the other hand, two card decks C and D are allocated to “sub player 3”. Two cards to be dealt to the sub player are determined from the two card decks C and D. In the determination, the same cards which dealt to the dealer are excluded from the two card decks C and D. Similarly, with respect to “sub player 5”, two cards to be dealt to the sub player are determined from two card decks E and F. Further, with respect to “sub player 8”, two cards to be dealt to the sub player are determined from two card decks G and H.
