[0012] 1. First Embodiment (1.1. Overview of Information Processing Device 1) An overview of an information processing device 1 according to the first embodiment will be described with reference to FIG. 1. The information processing device 1 is realized by one or more servers, and is configured to be able to communicate with a user terminal 3 by being connected to a WAN (Wide Area Network) 2 such as the Internet.

[0013] The user terminal 3 is realized by a mobile terminal such as a smartphone owned by a game user (hereinafter simply referred to as a user). The information processing device 1 accepts a request for the provision of game elements (hereinafter simply referred to as a provision request) from the user via the user terminal 3. Here, game elements are a general term for electronic data used by the user to progress through the game, and specifically include characters, items, cards, avatars, etc. In the following embodiment, an example will be described in which characters are provided as game elements.

[0014] When the information processing device 1 receives a request from a user to provide game elements, it selects one or more game elements from among those that are available and provides them to the user. The information processing device 1 is configured so that it does not provide more than a predetermined number of duplicate game elements that are available to the user. This allows the user to estimate the cost required to acquire the desired game elements. Each component will be described in detail below.

[0015] (1.2. Hardware Configuration of Information Processing Device 1) The hardware configuration of the information processing device 1 will be described with reference to FIG.

[0016] 2 is a block diagram showing the hardware configuration of the information processing device 1 according to this embodiment. The information processing device 1 includes a control unit 11 that controls the overall operation of the information processing device 1, and a storage unit 12 that functions as a work area when the control unit 11 executes various programs and in which various programs and various data are stored in advance.

[0017] Furthermore, the information processing device 1 includes a communication unit 13 that is connected to the user terminal 3 via a communication line and transmits and receives various data. The information processing device 1 may also include an operation input unit 14 that is configured with a keyboard, a mouse, etc. and receives input for various operations, and a monitor 15 such as a liquid crystal display device that displays various images.

[0018] The control unit 11, memory unit 12, communication unit 13, operation input unit 14, and monitor 15 are electrically connected to one another via a system bus 16. Therefore, the control unit 11 can access the memory unit 12, grasp the operation status of the operation input unit 14, display images on the monitor 15, and transmit and receive various data to and from other information processing devices such as the user terminal 3 via the communication unit 13.

[0019] (1.3. Functional configuration of information processing device 1) The functional configuration of the information processing device 1 will be described with reference to FIG.

[0020] 3, information processing device 1 includes a provision request receiving unit 21, a game element providing unit 22, a game element storage unit 23, and a provision result storage unit 24. Provision request receiving unit 21 and game element providing unit 22 are realized as functions of control unit 11. Game element storage unit 23 and provision result storage unit 24 are realized as functions of storage unit 12.

[0021] The provision request receiving unit 21 receives a request for providing a game element from a user, and communicates the provision request to the game element providing unit 22 .

[0022] Based on the notification from the provision request receiving unit 21, the game element providing unit 22 refers to the game element storage unit 23 and provides one or more game elements to the user. Furthermore, the game element providing unit 22 stores information specifying the game elements provided to the user in the provision result storage unit 24. The flow of providing game elements by the game element providing unit 22 will be described in detail later.

[0023] The game element storage unit 23 stores information that identifies game elements that can be provided to the user. The specific table configuration of the game element storage unit 23 will be described in detail later.

[0024] The provision result storage unit 24 stores information that identifies the game elements provided to the user. The specific table configuration of the provision result storage unit 24 will be described in detail later.

[0025] The above-described functional configuration may be realized by a CPU (Central Processing Unit) implemented as the control unit 11 executing a program to realize various functions, or may be realized by hardware.

[0026] When the function is realized by executing a program, the program may be stored in the storage unit 12 or in a non-transitory computer-readable recording medium. Alternatively, the function may be realized by reading a program stored in an external storage device and using so-called cloud computing. When the function is realized by hardware, the function may be realized by various circuits such as an ASIC, a SOC, an FPGA, or a DRP.

[0027] (1.4. Table Configuration of Game Element Storage Unit 23) 4 and 5, an example of the table configuration of game element storage unit 23 will be described. Game element storage unit 23 includes a character table T1, a user table T2, an element set table T3, an element set setting table T4, a unique set correspondence table T5, and a unique set setting table T6.

[0028] The character table T1 is a table that stores information about characters provided as game elements, and includes a character ID column and a name column. The character ID column holds a character ID for uniquely identifying a character. The name column holds the name of each character.

[0029] The user table T2 is a table that stores information about users who use the game, and includes a user ID column and a name column. The user ID column holds a user ID for uniquely identifying a user. The name column holds the name of each user.

[0030] The element set table T3 is a table that stores element sets, and includes an element set ID column and a name column. An element set is a collection of game elements such as characters, and one element set contains one or more game elements. The element set ID column holds an element set ID for uniquely identifying an element set. The name column holds the name of each element set.

[0031] The element set setting table T4 is a table that sets the game elements included in each element set. The element set setting table T4 has a No. column and a character ID column. The No. column holds a sequential number that uniquely identifies records in the table. The character ID column holds the character IDs of the characters included in the element set corresponding to the table.

[0032] In this embodiment, as shown in Fig. 4B, element set setting tables T4-1, T4-2, ..., T4-9 are set for each element set B01, B02, ..., B09, and the characters included in each element set are specified in each table. Note that, as shown in record D1, in this embodiment, it is permitted for the same character to be included more than once in one element set.

[0033] The unique set correspondence table T5 is a table that defines the correspondence between users and unique sets, and includes a user ID column and a unique set ID column. Here, a unique set is a set of element sets, and one unique set includes one or more element sets. The unique set ID column holds a unique set ID for uniquely identifying a unique set. In this embodiment, one unique set is set for each user, and therefore the unique set correspondence table T5 is defined so that each user and unique set correspond one-to-one.

[0034] The unique set setting table T6 is a table that specifies the element sets included in each unique set. The unique set setting table T6 has a No. column, a unique set ID, and an element set ID. By configuring the table in this way, the element sets included in each unique set and the game elements included in each element set are specified.

[0035] FIG. 5 is an image diagram showing the relationships between game elements (characters), element sets, unique sets, and users defined by the tables T1 to T6 shown in FIGS. 4A to 4C. As shown in FIG. 5, one unique set is set for each user. Each unique set includes one or more element sets. Each element set includes one or more game elements (characters in this embodiment). Game element providing unit 22 provides game elements by referring to game element storage unit 23 set in this way.

[0036] (1.5. Table configuration of the provision result storage unit 24) An example of the table configuration of the provision result storage unit 24 will be described with reference to Fig. 6. The provision result storage unit 24 includes a provision result table T7.

[0037] The provided result table T7 is a table that stores, for each user, information for identifying the game elements provided to that user. The provided result table T7 includes a No. column for uniquely identifying records in the table, a user ID column, an element set ID column, and a character ID column.

[0038] The user ID column holds the user ID of the user who made a request to provide a game element. The element set ID column holds the element set ID of the element set that includes the character provided to the user in response to the provision request. The character ID column holds the character ID of the character provided to the user in response to the provision request. Each time a game element is provided to a user, information about the provided character and the element set that includes that character is registered in the provision result table T7.

[0039] (1.6. Flow of providing game elements) The flow of providing game elements will be described with reference to Fig. 7. In step S110, the provision request receiving unit 21 receives a request from the user to provide game elements.

[0040] In step S120, game element providing unit 22 receives the contact from provision request receiving unit 21 and confirms the request to provide game elements. In step S130, game element providing unit 22 refers to game element storage unit 23 and acquires game elements to be provided to the user.

[0041] When acquiring game elements, the game element providing unit 22 first selects an element set included in a unique set set set set for the user who made the provision request. In this embodiment, the selection probability for an element set is set according to the number of characters included in the element set. The game element providing unit 22 selects an element set from the element sets included in the unique set by lottery based on the selection probability.

[0042] Hereinafter, a specific example will be described using the example shown in Fig. 8. As shown in Fig. 8, Unique set K01 includes two element sets, element sets B01 and B02. Element set B01 includes 50 characters, and element set B02 includes 100 characters. In this embodiment, the selection probability of an element set is set according to the ratio of the number of game elements included in each element set included in the unique set. Therefore, the selection probability of element sets B01 and B02 is set at a ratio of 50:100. With this configuration, the more game elements an element set includes, the more likely it is to be selected, which increases the interest in acquiring game elements.

[0043] Here, it is preferable that the lottery probability is determined by the number of game elements in the element set when the element set is set to be included in the unique set, and does not change as the user acquires game elements. In this way, when many game elements are provided from a specific element set, the lottery probability for that element set decreases, preventing a situation in which that element set becomes less likely to be selected.

[0044] After the element set is determined, a lottery is held for the characters in the determined element set. In this embodiment, the lottery for the characters in the element set is held at a ratio distributed among the total number of characters in the element set (i.e., 1 / (total number of characters in the element set)).

[0045] After the game elements are acquired in step S130 in this manner, game element providing unit 22 inquires about the acquisition results in step S140. Specifically, game element providing unit 22 refers to provision result storage unit 24 and determines whether the game elements acquired in step S130 have already been provided.

[0046] If game element providing unit 22 determines in step S150 that the acquired game element has already been provided, it returns to step S130 and repeats the process. On the other hand, if it determines that the acquired game element has not already been provided, game element providing unit 22 performs the process of step S160.

[0047] As mentioned above, in this embodiment, it is permitted for the same character to be included more than once in one element set (see record D1 in element set setting table T4-1 in FIG. 4B). For such game elements, it is determined whether the number of duplicates within the element set (the "predetermined number" in the claims) has been provided.

[0048] In step S160, the game element providing unit 22 provides the acquired game elements to the user. In step S170, the game element providing unit 22 registers, in the provision result storage unit 24, information specifying the game elements provided to the user.

[0049] As described above, the information processing device 1 according to this embodiment includes a provision request receiving unit 21, a game element providing unit 22, a game element storage unit 23, and a provision result storage unit 24. The provision request receiving unit 21 receives a request to provide a game element from a user. Based on the provision request, the game element providing unit 22 provides the user with a game element stored in the game element storage unit 23. The provision result storage unit 24 stores, for each user, information for identifying the provided game element.

[0050] Game element storage unit 23 stores a set of game elements as an element set, and also stores a set of element sets as a unique set for each user. When providing a game element, game element providing unit 22 selects an element set from the unique set set set for the user who has made the provision request, and provides one or more game elements from among the game elements included in the selected element set.

[0051] This configuration allows the user to set an element set, which is a set of characters, according to the user. When providing game elements, the element set is selected first, and then the game elements are selected, which increases the interest in acquiring game elements.

[0052] 2. Second Embodiment An information processing device 1 according to the second embodiment will be described with reference to Figures 9 and 10. The following description will focus on the differences from the first embodiment.

[0053] As shown in FIG. 9, the information processing device 1 according to the second embodiment differs from the first embodiment in that it includes a unique set setting unit 25 that can change the setting of the unique set in the game element storage unit .

[0054] The unique set setting unit 25 is configured to be able to add or delete element sets to or from the unique set set for each user by adding or deleting records to or from the unique set setting table T6 (see FIG. 4C) stored in the game element storage unit 23. The unique set setting unit 25 is also configured to be able to change the lottery probability of an element set within the unique set.

[0055] A specific explanation will be given below using the examples shown in Figures 10 and 11. Figures 10 and 11 show an example of adding an element set B03 to a unique set K01 set for user U01. Note that in Figure 11, characters that have already been provided to the user are crossed out.

[0056] 10, the unique set setting unit 25 adds a record indicated by D2 to the unique set setting table T6 stored in the game element storage unit 23. As a result, an element set B03 is added to the unique set K01, as shown in FIG.

[0057] Here, the probability of winning an element set included in the unique set K01 after the element set B03 is added is determined by the ratio of the numbers of game elements in the element sets B01, B02, and B03. In other words, the number of characters already provided by the user is not taken into consideration when determining the probability of winning. This configuration prevents the problem of the element set provided with many characters decreasing in the lottery probability, making it difficult to obtain characters that are not provided in that element set.

[0058] This configuration makes it easy to add or remove element sets for each user depending on the user's progress in the game or in accordance with a particular campaign, etc., thereby further increasing the interest in acquiring game elements.

[0059] 3. Third Embodiment An information processing device 1 according to a third embodiment will be described with reference to Figures 12 and 13. Information processing device 1 according to the third embodiment differs from that of the first embodiment in that game element providing unit 22 calculates in advance the order in which game elements are provided.

[0060] In the third embodiment, game element providing unit 22 refers to game element storage unit 23 and calculates in advance the order in which game elements will be provided for each user. Game element providing unit 22 registers the pre-calculated order in which game elements will be provided in provision result storage unit 24. When provision request receiving unit 21 receives a provision request from a user, game element providing unit 22 refers to provision result storage unit 24 and provides the game elements in the order registered in provision result storage unit 24.

[0061] As shown in FIG. 12, the provision result table T7 in the third embodiment further includes a provisioned column. The provided column holds a flag for identifying whether the game element specified in the record has already been provided.

[0062] The flow of providing game elements will be described with reference to Figure 13. In step S301, game element providing unit 22 references game element storage unit 23 and calculates the order in which game elements will be provided for each user. Specifically, a lottery is held for element sets in a unique set set for each user, based on the lottery probability for each element set, to select one or more element sets. Then, a lottery is held for game elements included in the selected element set, to determine the order in which game elements that can be provided to the user will be provided. In step S302, game element providing unit 22 registers the calculated order in which game elements will be provided in provision result storage unit 24.

[0063] In step S310, the provision request receiving unit 21 receives a request to provide a game element from the user. In step S320, the game element providing unit 22 receives the contact from the provision request receiving unit 21 and confirms the request to provide a game element.

[0064] In step S330, the game element providing unit 22 references the provision result table T7 in the provision result storage unit 24, and acquires the game elements to be provided to the user. Specifically, for the user who made the provision request, the game elements identified by the records in the provision result table T7 where the provided column is "0 (uncompleted)" are acquired in ascending order of the value in the No column. In step S340, the game element providing unit 22 provides the acquired game elements to the user.

[0065] In step S350, the game element providing unit 22 updates the provided column of the providing result table T7 to "1 (provided)" for the record that identifies the provided game element.

[0066] In this way, in the information processing device 1 of this embodiment, the order in which game elements are provided to a user is calculated in advance. This configuration eliminates the need to perform a game element acquisition process and a process to determine whether or not a game element has already been provided for each acquisition request from a user, and allows for a rapid provision process. Furthermore, it is possible to manage which game elements have already been provided to each user and which game elements will be provided in the future.

[0067] 4. Fourth Embodiment An information processing device 1 according to a fourth embodiment will be described with reference to Figures 14 and 15. The information processing device 1 according to the fourth embodiment differs from the above embodiments in that the order in which game elements are provided for each element set is calculated in advance.

[0068] When provision request receiving unit 21 receives a provision request from a user, game element providing unit 22 refers to game element storage unit 23 and performs selection (lottery) of an element set for the unique set corresponding to the user. Game element providing unit 22 refers to provision result storage unit 24 for the element set determined by lottery and provides the game elements in the order registered in provision result storage unit 24.

[0069] 14, a provision result table T7 in the fourth embodiment is prepared for each element set included in the unique set. The game element providing unit 22 references the provision result table T7 corresponding to the element set determined by lottery, and determines the game elements to be provided to the user.

[0070] The flow of providing game elements will be described with reference to Fig. 15. In step S410, the providing request receiving unit 21 receives a request to provide game elements from the user. In step S420, the game element providing unit 22 receives a request from the providing request receiving unit 21 and provides the game element. Check the request to provide the element.

[0071] In step S430, the game element providing unit 22 selects an element set included in the unique set set set for the user who made the provision request. That is, the game element providing unit 22 selects an element set from among the element sets included in the unique set by lottery based on the lottery probability set for each unique set.

[0072] In step S440, the game element providing unit 22 references the providing result storage unit 24 and acquires game elements to be provided to the user from the providing result table T7 corresponding to the selected element set. Specifically, for the providing result table T7 corresponding to the selected element set, the game elements identified by the records having "0 (uncompleted)" in the provided column are acquired in ascending order of the value in the No column. In step S450, the game element providing unit 22 provides the acquired game elements to the user.

[0073] In step S460, the game element providing unit 22 updates the provided column of the providing result table T7 to "1 (provided)" for the record that identifies the provided game element.

[0074] In this way, in the information processing device 1 of this embodiment, the order in which game elements are provided is calculated in advance for each element set. With this configuration, when adding an element set to a unique set, it is not necessary to change the order in which game elements are provided that has already been determined in the providing result table T7, and the unique set can be added through simple processing.

[0075] <5. Other embodiments> Although the embodiments and their modifications of the present invention have been described above, the application of the present disclosure is not limited to the above. For example, in the above embodiment, the user terminal 3 is realized as a mobile terminal such as a smartphone, but the present disclosure is not limited to this example. For example, the user terminal 3 may be realized by installing software on a home PC or the like.

[0076] It should be noted that the table configuration in the above embodiment is merely an example of an implementation method. For example, the provision result table T7 stores the provided game elements, but is not limited to this example, and may also store game elements that have not been provided to the user.

[0077] In the above embodiment, one unique set is set for each user, but this is not limiting. That is, the unique set correspondence table T5 may have a table configuration in which multiple unique sets correspond to one user.

[0078] Furthermore, in the fourth embodiment described above, the provision result table T7 stores the provision order for each element set, but this is not limited to this example. For example, the provision order of game elements in an element set may be calculated when providing the game elements by generating pseudo-random numbers with the user ID as an initial value for the game elements in the element set. In this case, since the user ID is unique and unchanging for each user, the calculated provision order is unique for each user, and the same provision order is calculated each time for the same user. Therefore, the provision result table T7 only needs to store up to which game element in the calculated provision order each element has been provided to each user.

[0079] Furthermore, the present invention can also be realized as a program that causes a server to function to realize the above-described information processing device.

[0080] Furthermore, the present invention can also be realized as a computer-readable non-transitory recording medium storing the above-mentioned program.

[0081] While various embodiments of the present invention have been described, they are presented by way of example only and are not intended to limit the scope of the invention. The novel embodiments may be embodied in various other forms, and various omissions, substitutions, and modifications may be made without departing from the spirit of the invention. Such embodiments and modifications are intended to be included within the scope and spirit of the invention, as well as within the scope of the inventions and their equivalents as set forth in the claims.
