The present invention relates to a method of shuffling playing cards used for card games, and more particularly, to shuffled playing cards which are completely randomly arranged by performing a shuffle multiple times independently using multiple card shuffling devices and to a shuffling method thereof.
In poker, baccarat, bridge, blackjack, and other card games, a dealer sets one or more decks (six to nine or ten decks) of playing cards in a card shooter or the like and deals cards to game players by shooting the cards one by one out of the card shooter or the like. In so doing, to ensure fairness of the games, the cards not arranged with regularity but arranged at random need to be dealt. Therefore, a game host has to shuffle the playing cards sufficiently randomly before the playing cards are set in the card shooter, and arrangement of the playing cards set in the card shooter must not be known to players and the dealer, or anyone.
International Publication No. WO2009/069708 discloses a method of manufacturing and shipping packages of playing cards shuffled in random and unique arrangement order using a shuffling device in a shuffling process. It is conceivable that to use the cards randomly arranged for card games, a game host shuffles the cards using the shuffling device before the start of play, and International Publication No. WO2009/069708 has an object to provide shuffled playing cards and a manufacturing method thereof 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. Furthermore, International Publication No. WO2009/069708 discloses that the shuffling devices perform a process of shuffling the cards in a random manner multiple times, and therefore the shuffled playing cards can be arranged more randomly.
In a conventional system, a method of shuffling cards using a set of random numerical values output from a random generator based on a command from a CPU (processor) in a shuffling device has been widely used. In this case, the information about the set of random numerical values is stolen or leaks to the outside due to an unauthorized access to the CPU (processor), or the like, resulting in the information about the arrangement of the shuffled playing cards being illegally acquired, and therefore there is a problem of possible cheating.
The present invention has been made in view of the above problems, and has an object to provide a system in which multiple shuffling devices are connected in series to one another, and shuffle cards using sets of random numerical values output from respective random generators based on commands from multiple CPUs (processors) which are independent from one another, and wiredly or wirelessly connected with the respective multiple shuffling devices, and then the subsequent shuffling devices connected in series shuffle the cards in the same manner, this shuffling process is performed across the multiple shuffling devices, so that the cards are arranged randomly. Furthermore, even if the information about the sets of random numerical values output from the multiple random generators is stolen due to an unauthorized access to the multiple CPUs (processors), 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 invention further has an object to provide a system in which in each of the multiple shuffling devices, the cards are shuffled using the set of random numerical values selected from the sets of random numerical values output for each multiple sets from the random generator based on a command from the CPU (processor), and therefore even if the information about the multiple sets of random numerical values in the random generator is stolen due to an unauthorized access to the CPU (processor), or the like, it becomes difficult to identify the selected and used set of random numerical values by which the cards have been shuffled, and therefore the possibility that the arrangement of the shuffled cards is recognized is further reduced.

An integrated product of the number of pockets in each of the multiple shuffling devices and the number of the multiple shuffling devices may be equal to or larger than the total number of cards of the card set.
The processor may output multiple sets of random numerical values from the corresponding random generator, and the sequencer or controller may be configured to select and use one out of the multiple sets of random numerical values to control the corresponding shuffling device.
A final shuffling device which finally shuffles the cards of the card set among the multiple shuffling devices further includes gathering means which mechanically gathers the cards sorted by the final shuffling device, and the shuffled playing cards may be completely manufactured by gathering the sorted cards by the gathering means as a single stack and packing the shuffled card set into a package by an automatic packaging machine.
A unique ID may be generated for each of the individual shuffled card sets, and may be associated with the shuffled card set.
The present invention includes shuffled playing cards manufactured using the above-described shuffling system.
The shuffled playing cards may be double packed into the package by the automatic packaging machine.

Before describing embodiments of a shuffling system of the present invention, a mechanism in a shuffling device provided with multiple pockets will be described in which the cards are arranged randomly by performing multiple times a shuffle by which a set of cards to be shuffled is sorted one by one into any of the pockets.
For example, it is assumed that the cards of eight decks (52 cards×eight decks=416 cards) are shuffled and arranged randomly. As illustrated in
Then, as illustrated in
Next, an embodiment of the shuffling system according to the present invention will be described with reference to
The sets (10A to 10N) of random numerical values output from the respective random generators (103a to 103k) based on the commands from the respective multiple CPUs (processors 102a to 102k) which are independent from one another are transmitted to the respective sequencers or controllers (101A to 101N) which are wiredly or wirelessly connected with the respective multiple CPUs (102a to 102k), and the multiple sequencers or controllers (101A to 101N) uses the respective sets (10A to 10N) of random numerical values received from the respective random generators (103a to 103k) to control the shuffles of the respective shuffling devices (100A to 100N) which are provided with or connected to the respective multiple sequencers or controllers (101A to 101N). Here, as in the CPU 102j in
Although the above description is repeated, since the multiple shuffling devices (100A to 100N) are provided, the multiple shuffling devices (100A to 100N) are controlled by the corresponding sequencers or controllers (101A to 101N), respectively, using the sets (10A to 10N) of random numerical values output from the respective random generators (103a to 103k) based on the commands from the respective different CPUs (102a to 102k). Note that on the factory's manufacturing line, while a certain card set 1t is shuffled by the shuffling device 100B after being shuffled by the shuffling device 100A, a subsequent card set 1t is shuffled by the shuffling device 100A, so that the shuffles are performed in sequence. To do so, new sets (10A to 10N) of random numerical values are output from the respective random generators (103a to 103k) in sequence, and then are transmitted to the corresponding sequencers or controllers (101A to 101N), respectively. For example, the random generator 103a outputs and transmits a first set 10A of random numerical values, a second set 10A of random numerical values, a third set 10A of random numerical values, and sequential sets 10A of random numerical values in sequence to the sequencer or controller 101A (the first set 10A of random numerical values, the second set 10A of random numerical values, the third set 10A of random numerical values, and the sequential sets 10A of random numerical values are different from one another). Here, it is assumed that the information about the sets (10A to 10N) of random numerical values output from the respective multiple random generators (103a to 103k) in a certain period of time is stolen due to an unauthorized access to the multiple CPUs (102a to 102k). For example, it is assumed that the information for three sets of the first set 10A, the second set 10A, and the third set 10A of random numerical values as the sets of random numerical values output from the random generator 103a for a certain period of time, and the information for five sets of the first set 10B, the second set 10B, the third set 10B, the fourth set 10B, and the fifth set 10B of random numerical values as the sets of random numerical values output from the random generator 103b for the certain period of time are stolen. In this case, it is not easy to precisely determine whether a certain set 10A of random numeral values (e.g., the first set 10A of random numerical values) is used for shuffle of the card set 1t or for shuffle of the subsequent card set 1t, in the shuffling device 100A. Even if the shuffled card set 1t for which the set 10A of random numerical values (e.g., the first set 10A of random numerical values) is used is identified by someone, the multiple CPUs (102a to 102k) are independent from one another by disconnecting the communication networks, and therefore shuffled card sets 1t for which certain sets of random numerical values output from the random generators corresponding to the other shuffling devices are used cannot be recognized one after another based on the identified information. For example, it cannot be recognized whether the sets 10B of random numerical values (e.g., the first set 10B of random numerical values) output from the random generator 103b are used for shuffle of the card set 1t or for shuffle of the subsequent card set 1t one after another, and therefore it is not easy to precisely determine whether the set 10B of random numerical values (e.g., the first set 10B of random numerical values) is used for shuffle of the card set 1t or for shuffle of the subsequent card set 1t, as with the set 10A of random numerical values (e.g., the first set 10A of the random numerical values). The information about the arrangement of a card set 1s shuffled through the multiple shuffling devices (100A to 100N) cannot be obtained unless all the sets (10A to 10N) of random numerical values used for shuffles of the card set is are precisely recognized (for example, unless all the sets of random numerical values such as which number set 10A among the sets 10A of random numerical values, and which number set 10B among the sets 10B of random numerical values are precisely recognized). Therefore, it can be said that it is nearly impossible to obtain the information about the arrangement of the cards.
Next, a schematic structure of each shuffling device will be described with reference to
The card stack holder 200 has a predetermined number of pockets 200a to 200g. Note that, although in the configuration illustrated in
With the configuration described above, the shuffling device 100A is controlled through the sequencer or controller 101A to alternately slide the card feeder 201 to a position facing any of the pockets 200a to 200g and send out the card 1 from the card feeder 201 to the pocket (200a to 200g). Note that, the sequencer or controller 101A receives the set 10A of random numerical values output from the random generator 103a based on a command from the CPU 102a, and determines the position to move the card feeder 201 to, i.e., the position facing one of the pockets 200a to 200g using the received set 10A of random numerical values. The sequencer or controller 101A is configured to have a memory (not illustrated) storing a look-up table for assigning any of the pockets 200a to 200g based on the set 10A of random numerical values. For example, when the first digit of the set 10A of random numerical values is “3,” the sequencer or controller 101A controls to move the card feeder 201 to the position facing the third pocket 200c from the top based on the look-up table, and send out the first card 1 to the pocket 200c. In this way, the card set 1t placed on the card feeder 201 is sent out one by one in a random order to any of the pockets 200a to 200g of the card stack holder 200. When all the cards 1 loaded in the card feeder 201 are sent out to the card stack holder 200, the partition plates 205a to 205f recede from the inside of the card stack holder 200 and consequently cards 1 sorted into the pockets 200a to 200g of the card stack holder 200 are taken out of the shuffling device 100A as a single stack. However, as gathering means of the cards 1 sorted into the above pockets 200a to 200g, the receding of the partition plates 205a to 205f is not absolutely necessary, and any alternative means may be used. For example, the cards may be taken out of the pockets 200a to 200g using a robot arm or the like. The above is a single shuffling process performed by the shuffling device 100A.
Note that the structure of the shuffling device is not limited to the above embodiment. For example, it is also conceivable that the shuffling device is of a structure (not illustrated) where after the set of cards to be shuffled is sorted previously into the multiple pockets for each rank and suit, the sequencer or controller controls to perform the shuffle based on the set of random numerical values output from the random generator based on a command from the CPU (processor) so that the cards are taken one by one out of the multiple pockets as a stack. It is only required that the sequencer or controller is wiredly or wirelessly connected to a position at which the shuffling device can be controlled, and therefore the sequencer or controller may be provided inside or outside the shuffling device. Similarly, it is only required that the random generator has a function of receiving the command from the CPU and transmitting the set of random numerical values directly or indirectly to the sequencer or controller, and therefore the random generator may be included in the CPU or in a device separately provided outside.
Next,
Note that, as described above, the multiple sequencers or controllers (101A to 101N) are configured to receive the respective sets of random numerical values (10A to 10N) output from the respective random generators (103a to 103k) based on the commands from the respective multiple CPUs (102a to 102k) to control the respective shuffling devices (100A to 100N), and the CPUs (102a to 102k) are configured to instruct the respective random generators (103a to 103k) to output the respective sets of random numerical values at a time or for each multiple sets at intervals of short time duration so that the multiple sequencers or controllers (101A to 101N) receive the respective sets of random numerical values at a time or for each multiple sets at intervals of short time duration. Each of the multiple sequencers or controllers (101A to 101N) is configured to select one set among the received multiple sets of random numerical values to control the corresponding shuffling device (100A to 100N) using the set of random numerical values selected by the sequencer or controller itself. For example,
Next, a flow of the cards in a manufacturing process including a shuffling process in the embodiment of the shuffling system of the present invention will be described. A card set 1t including the cards made up of a predetermined number of decks grouped together, the cards being created through a printing process in which suit and rank are printed on one side of card base paper and a design is printed on the other side, and through a cutting process in which the printed card base paper is cut into individual cards, is loaded in the card feeder 201 of the shuffling device 100A in the initial step of the shuffling process. The card set 1t is sent out one by one in a random order to any of the pockets (200a to 200g) of the card stack holder 200 by the sequencer or controller 101A using the set 10A of random numerical values output from the random generator 103a based on the command from the CPU 102a. When all the cards are sent out to the card stack holder 200, the partition plates 205a to 205f recede from the inside of the card stack holder 200 and consequently cards 1 sorted into the pockets 200a to 200g of the card stack holder 200 are taken out of the shuffling device 100A as a single stack.
The card set taken out of the shuffling device 100A as a single stack by the above gathering means is automatically or manually loaded in a card feeder 211 of the shuffling device 100B, is sorted one by one into any of the pockets (210a to 210g) of the card stack holder 210 by the sequencer or controller 101B using the set 10B of random numerical values output from the random generator 103b based on the command from the CPU 102b, and is then shuffled. The similar processes are repeated until the card set reaches the final shuffling device (shuffling device 100N in Embodiment 1) which is provided most downstream of a predetermined number of shuffling devices connected in series to one another. Note that the integrated product of the number of pockets in each shuffling device (100A to 100N) (for example, seven pockets in the shuffling device 100A, and seven pockets in the shuffling device 100B) and the number of all the shuffling devices (100A to 100N) for shuffling the card set 1t is equal to or larger than the total number of cards of the card set 1t (e.g., 416 cards in the case of an 8-deck shuffled playing cards), and finally the cards can be completely randomly arranged. The cards sorted into the multiple pockets in the above-described final shuffling device are automatically or manually taken out of the final shuffling device as a single stack by the gathering means by which the partition plates of the card stack holder recede from the inside of the card stack holder.
Note that it may be checked in each shuffling process whether the card set includes a predetermined number of cards (416 cards in the case of an 8-deck shuffled playing cards). It can be inspected whether the cards are lost in the shuffling processes, or whether some cards are added or removed in the shuffling processes.
Note that when the final shuffling device (in Embodiment 1, the shuffling device 100N) which performs the final shuffling process finishes the shuffle, a shuffled card ID to be assigned to the set of shuffled playing cards completed through the final shuffling process is generated. This shuffled card ID is generated as a unique ID for each shuffled playing card set 1s. The generated shuffled card ID is associated with predetermined information out of production information of the shuffled playing card stored in the database (not illustrated). Any desired type and volume of such information may be used, but information which identifies the manufacturing line or shuffling devices involved in the shuffling process is particularly important.
Specifically, if there are multiple manufacturing lines, the manufacturer of the shuffled playing card set 1s according to the present embodiment assigns a unique manufacturing line ID to each manufacturing line in advance. Then, upon generation of a shuffled card ID, the generated shuffled card ID is registered in the database by associating the shuffled card ID with the manufacturing line ID of the manufacturing line involved in the manufacture of the shuffled playing cards. However, IDs are not limited to such manufacturing line-related IDs. Alternatively, a shuffling device ID may be assigned to each shuffling device in advance and the shuffled card ID may be registered in the database by associating the shuffled card ID with all the shuffling device IDs involved in the shuffling process. Note that the database may be provided either in or outside the shuffling system.
The generated shuffled card ID is printed on the adhesive label 3 as a bar code 4 by a printing machine. Then, the adhesive label 3 on which the bar code 4 of the shuffled card ID is printed is used to seal a paper box (package) 2. The details will be described later.
Note that as a method of using the ID, for example, if a customer who has purchased a shuffled playing card set 1s notices any defect in the purchased cards, the customer informs the manufacturer of the shuffled playing card set is of the shuffled card ID. In so doing, the customer may send the adhesive label 3 on which the bar code 4 is printed to the manufacturer so that the manufacturer will read the shuffled card ID using a bar-code reader. Alternatively, the customer may read the shuffled card ID using a bar-code reader or the like and send the obtained data to the manufacturer via communications means such as an e-mail. Consequently, by searching the database using the shuffled card ID, the manufacturer can identify a manufacturing line or a shuffling device that may have a problem. In such a case, the manufacturer can alert customers about the shuffled playing card sets is manufactured on the same manufacturing line or shuffling device in the same period and take measures, if necessary, such as requesting the customers to discard the product or recalling the product. Also, by inspecting the identified manufacturing line or shuffling device, the manufacturer can prevent a recurrence of the defect.
Also, the manufacturer may deliver the shuffled playing card set 1s to the customer together with a portable storage medium containing data (shuffled card ID and related information) on the shuffled playing card set 1s to be delivered by downloading the data from the database. Note that any data structure (format) may be used for the data downloaded from the database to the storage medium as long as the data is readable on the customer's computer. Then, if the customer finds a defect such as a bent card, the customer can read the shuffled card ID of the defective shuffled playing card set Is using a bar-code reader or the like and search data on the storage medium based on the shuffled card ID thus acquired. Also, based on search results, the customer can take measures such as discarding shuffled playing card sets Is related to the same manufacturing line or shuffling device. Besides, even if fraudulent shuffled playing cade sets are mixed in items delivered to the customer, the customer can check the shuffled card IDs of the delivered items with the shuffled card IDs stored in the storage medium. Then, any shuffled playing card set whose shuffled card ID is not contained in the storage medium provided at the time of delivery can be determined to have been mixed for fraudulent purposes. This prevents mixing of fraudulent items by a third party.
As described above, as illustrated in
Note that the present invention includes the shuffling system in which the final shuffling device which finally shuffles the cards of the card set among the multiple shuffling devices further includes the gathering means which mechanically gathers the cards sorted by the final shuffling device, so that the shuffled playing cards are completely manufactured by gathering the sorted cards by the gathering means as a single stack and packing the shuffled card set into a package by an automatic packaging machine (not illustrated).
Note that the present invention includes the shuffling system in which a unique ID is generated for each of the individual shuffled card sets, and is associated with the shuffled card set. The present invention includes shuffled playing cards manufactured using the above-described shuffling system.
The bar code 4 and a specification table 5 are printed on the adhesive label 3. As described above, the bar code 4 represents an ID (shuffled card ID) which can uniquely identify the shuffled playing card set 1s. The specification table 5, which is not absolutely necessary, can contain any information about the playing cards, such as manufacturing information (a product number, a date of manufacture, and manufacturing factory information), a serial number, a product name, a color, and customer information (such as a casino's name). In addition to or instead of the bar code 4, an RFID tag may be attached to the adhesive label 3.
Since the shuffled playing card set 1s has a mouth of the lid of the package 2 sealed with the adhesive label 3, in order to use the shuffled playing card set 1s, the adhesive label 3 has to be removed or broken. To prevent cheating, preferably the adhesive label 3 is made of material which, once peeled off, cannot be returned to its original attached state or is configured to be broken at least partially upon application of an external force peeling off the adhesive label 3. The shuffled playing cards wrapped with the package by the automatic packaging machine (not illustrated) has a mouth of the lid of the package 2 sealed with the adhesive label 3, and is further wrapped with a transparent shrink film (not illustrated), resulting that the shuffled playing cards are double packed. Thus, the shuffle, the attachment of ID, and the packaging are automatically performed (without being directly touched by a person).
As described above, since the shuffled playing card set 1s contains shuffled playing cards shuffled in a sufficiently random manner and packed individually into the package 2 sealed with the adhesive label 3 in the shuffle system according to the present embodiment, in order to use the shuffled playing card set 1s in a game, it is only necessary to open the package 2 and set the playing card set is promptly in a card shooter (not illustrated). This eliminates the need for a game host to shuffle the playing cards. It also eliminates the possibility of cheating such as insertion/removal or switching of cards during shuffling.
While various embodiments of the present invention have been described above, the above-described embodiments may be modified by those skilled in the art within the scope of the present invention. The device of the present embodiment may be appropriately modified as required for the game to be applied.
