The present invention provides shuffled playing cards which eliminate the need for a game host to shuffle cards before games by taking a lot of time as well as eliminate the possibility of cheating. A shuffled playing cards (1) obtained by shuffling a predetermined number of decks of playing cards (12) using a shuffling machine is packaged as an individual pack. The shuffled playing cards (1) is individually packaged and sealed with an adhesive label (13). A bar code (13a) which represents a unique shuffled card ID has been printed on the adhesive label (13). The shuffled card ID is registered in a database by being associated with information which allows identification of a shuffling machine used to shuffle the playing card set.

A shuffling system of the present invention 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.

The present disclosure relates to a playing card, where a suit and a rank are printed on one surface of a card base sheet, a back pattern is printed on a back surface, an intermediate layer having a black layer or a color layer similar to black is provided on the card base sheet to make transmission of visible rays difficult, and ink containing no carbon is used for printing the suit and the rank. The intermediate layer is configured to prevent transmission of visible rays from the back surface. The suit and the rank printed with the ink containing no carbon are configured to transmit infrared rays. The intermediate layer and the suit and rank printed with the ink containing no carbon are configured such that it is difficult for both the visible rays and the infrared rays to distinguish the suit and the rank from the back surface.

There is provided a shuffled playing card, wherein a suit and a rank are printed on one surface of a card base sheet, and a back pattern is printed on another surface, different sheet IDs for one card base sheet or each of a plurality of card base sheets are printed on the card base sheet, one deck or a plurality of decks are formed by individual cards cut by a cutting machine from the card base sheet, the one deck or the plurality of decks are shuffled by a shuffle machine to form a set of shuffled playing cards, different shuffled playing card IDs for each set are assigned to the shuffled playing card as ID codes, and the sheet ID of the playing card constituting the shuffled playing card and the shuffled playing card ID are associated with each other in a database.

There is provided a system and method for generation of vision recognition references from user-selected content. The method comprises receiving data corresponding to a user selected content, generating a vision recognition reference from the data, associating a game behavior descriptor with the vision recognition reference, wherein the game behavior descriptor correspond to a game behavior instance, and storing the vision recognition reference and the associated game behavior descriptor in a database, wherein the database includes a plurality of pre-defined vision recognition references, and wherein each of the plurality of pre-defined vision recognition references correspond to at least one pre-defined game behavior descriptor. The method may further comprise receiving user input corresponding to the user-selected content, retrieving the vision recognition reference and the associated game behavior descriptor from the database and initiating the game behavior in a corresponding game.

There is provided a shuffled playing card, wherein a suit and a rank are printed on one surface of a card base sheet, and a back pattern is printed on another surface, different sheet IDs for one card base sheet or each of a plurality of card base sheets are printed on the card base sheet, one deck or a plurality of decks are formed by individual cards cut by a cutting machine from the card base sheet, the one deck or the plurality of decks are shuffled by a shuffle machine to form a set of shuffled playing cards, different shuffled playing card IDs for each set are assigned to the shuffled playing card as ID codes, and the sheet ID of the playing card constituting the shuffled playing card and the shuffled playing card ID are associated with each other in a database.

A method including, manufacturing individual playing cards; shuffling, using a shuffling machine with multiple pockets, a multiple number of decks of the playing cards at random in a factory utilizing at least a first card feeding step and a second card feeding step; detecting, using an imaging device and an image processing unit, a rank and a suit of each of the cards; counting, using the image processing unit, the number of each rank and each suit; inspecting, using the image processing unit, during or after the shuffling of the decks of playing cards, but before packaging, whether or not there is an excess or deficiency in the number of the rank or the suit contained in the multiple number of decks of the playing cards; and, after the inspecting step, packaging a set of the shuffled decks of the playing cards in an individual package.

The present invention provides shuffled playing cards which eliminate the need for a game host to shuffle cards before games by taking a lot of time as well as eliminate the possibility of cheating. A shuffled playing cards (1) obtained by shuffling a predetermined number of decks of playing cards (12) using a shuffling machine is packaged as an individual pack. The shuffled playing cards (1) is individually packaged and sealed with an adhesive label (13). A bar code (13a) which represents a unique shuffled card ID has been printed on the adhesive label (13). The shuffled card ID is registered in a database by being associated with information which allows identification of a shuffling machine used to shuffle the playing card set.

Systems and methods for designing and selling a user-generated game offered for sale via an online retail platform are provided. A user can input user-specified game information via a computing device over a network instructions for the development of the components of a game are automatically created based at least in part on the user-specified game information. Moreover, the systems and methods may further include transmitting the instructions for the development of the components of the game to an online retail platform, print on demand manufacturing the game, and thereafter offering the game for sale or rent via the online retail platform.

A duplicate playing card output and recycling device is provided for an electronic game system to print, output, and recycle playing cards. The device is connected to the game system to print a duplicate playing card having the same suit and numeral as that dealt by the electronic game system. The device includes a printing device and a recycling device. The printing device is able to print the duplicate playing card to the player. The recycling device is able to recycle the duplicate playing card. The device enhances the fun and excitement of the game, and the duplicate playing card won't be arbitrarily disposed.
