[0008] <System configuration> Fig. 1 is a diagram showing an example of the system configuration of a game system 1 according to this embodiment. The game system 1 shown in Fig. 1 includes a game server 10 (an example of a server) and one or more terminals 20. The game server 10 and the terminals 20 are connected to each other so as to be able to communicate with each other via a communication network N such as the Internet, an intranet, a wireless LAN, or mobile communication.

[0009] The server 10 is an information processing device that performs some of the functions required for the terminal 20 to provide a game, such as managing various information related to users (which may also be called players) and executing some of the game processing. The server 10 may be composed of one or more information processing devices, or may be configured using a virtual server (such as a cloud server). The server 10 may also be called a computer.

[0010] The terminal 20 is an information processing device that provides a game to a user, and the user can play the game according to this embodiment by operating the terminal 20. The terminal 20 is, for example, a computer such as a mobile phone (including a smartphone), a tablet, a personal computer, an arcade game device, or a consumer game device. The terminal 20 may notify the server 10 of its own location detected using a GPS (Global Positioning System) or the like. The terminal 20 may also be called a computer.

[0011] <Hardware configuration> 2 is a diagram showing an example of the hardware configuration of the server 10 and the terminal 20. The game server 10 and the terminal 20 each have a processor 11 such as a CPU (Central Processing Unit) or a GPU (Graphical Processing Unit), a memory (for example, RAM (Random Access Memory) or ROM (Read Only Memory)), a storage device 12 such as an HDD (Hard Disk Drive) and / or an SSD (Solid State Drive), a network IF (Network Interface) 13 for wired or wireless communication, an input device 14 for accepting input operations, and an output device 15 for outputting information. The input device 14 is, for example, a keyboard, a touch panel, a mouse, and / or a microphone. The output device 15 is, for example, a display, a touch panel, and / or a speaker.

[0012] <First example> A system according to a first example of the present invention allows users to exchange game content acquired by lottery among themselves. An example of in-memory data management, screen content displayed on a display, and data processing by a processor in a computer system that realizes this system will be described below. In the following, it is assumed that a server 10 and a terminal 20 communicate with each other via a network N, and the server 10 processes data (requests, etc.) received from the terminal 20, transmits the data to the terminal 20, and displays the screen on the display.

[0013] [Example of data stored in memory] User Data: Stores each user's account information, a list of game media owned, and exchange history. Game media data: Stores information about in-game game media (items, characters, game objects, etc.), attributes (rarity, category, etc.), and owner information. Exchangeable list: Stores a list of game media that you wish to exchange and other game media that can be exchanged for it. Lottery results: Stores the results of the game content drawn based on the user's request.

[0014] [Example of a screen displayed on the display] Lottery result screen (Figure 3): Displays the game content selected in response to the user's request. Exchangeable game media list screen (FIG. 4): A screen on which the user can check a list of exchangeable game media. In this embodiment, this screen is integrated into the exchange request screen. Exchange request screen (Figure 4): This screen allows you to exchange specific game content with other users. Exchange approval screen (Figure 5): This screen allows you to approve or reject exchange requests from other users.

[0015] [Example of data processing by a processor] Lottery processing: Based on a request from a user (terminal 20), the processor randomly selects a game medium from a first set containing multiple game media and displays the result to the user. The lottery result screen displaying the lottery result on the terminal of the first user is the first screen, and the lottery result screen displaying the lottery result on the terminal of the second user is the second screen. 3, it is possible to specify whether or not each game medium is eligible for exchange. On the lottery result screen 300, when a game medium 302 to be exchanged is selected by selecting a check box 304 and a button 308 for displaying an exchangeable list is selected, an exchangeable list showing a list of game media that can be exchanged for the specified game medium is displayed. On the other hand, if the user selects the receive button 306 without specifying the game medium to be exchanged, the game medium selected by the lottery will be awarded to the user. The game medium awarded to the user can be used in games such as quests, but the game medium in its pre-award state cannot be used in games.

[0016] Generation of exchangeable list: Among the game media selected by lottery, the game media designated by a user (e.g., the first user / second user) are added to an exchange list, and the list is made visible to other users (e.g., the second user / first user). This allows the user to check the game media that can be exchanged with other users. For example, a user who has executed a first lottery to select a game medium from the first set may be presented with an exchange list that includes the game medium selected from the first set.

[0017] [Management of the exchange process] The processor controls the game content designated by the user so that it can be exchanged with other users, including setting the status of the game content to "exchangeable" so that other users can access the game content. A list of game media that the user wishes to exchange and game media that can be exchanged (exchangeable list) is displayed, and the user can select the game media that he or she wishes to exchange from this list.

[0018] [Handling successful and unsuccessful exchanges] As shown in Figure 4, in the exchangeable list 402 included in the exchange request screen 400, check the check box 406 of the game medium 404 you wish to acquire, check the check box 410 of the game medium 408 you wish to use in the exchange, and press the exchange request button 412 to request an exchange from the user who owns the game medium 404. For example, when a request for exchange of a first game medium selected by the first user from the lottery results with a second game medium set as exchangeable by the second user is received from the first user, the second user is notified of this. For example, on the exchange approval screen 500 of FIG. 5, if the exchange request is accepted by pressing the approval button 506 and the exchange is completed (e.g., if the second user accepts), the processor updates the game media lists of both users, exchanges game media 502 and game media 504, and grants them to each user. If the reject button 508 is pressed on the exchange approval screen 500 and the second user does not consent, the processor adds the game medium desired to be exchanged (e.g., the first game medium) to the exchangeable list and provides other users with an opportunity to present another game medium that can be exchanged for this game medium. When "Request an Exchange," "Add to Exchange List," or "Back" is selected on the exchange request screen 400, the screen returns to the lottery result screen 300. Here, the game media requested for exchange or added to the exchange list are set as unavailable (e.g., grayed out) on the lottery result screen 300. When "Receive" is selected on the lottery result screen 300, all game media in the lottery results other than the game media set as unavailable are granted to the user.

[0019] [Exchangeable list update and notification] The processor periodically updates the exchangeable game media list and notifies the user of information about newly exchangeable game media and game media added to the exchangeable game media list, thereby enabling the user to always access the latest exchangeable game media.

[0020] In this way, the processor performs a series of processes, such as drawing lots for game media, generating and updating the exchangeable list, managing the exchange process, and notifying users of the exchange results. These processes provide a foundation for efficient and smooth game media exchange between users.

[0021] <Second example> In a second example, if the user does not specify a game medium with which they wish to exchange the game medium, the game medium is added to the exchangeable list. Below, examples of data stored in memory, screens displayed on a display, and data processing by a processor in a computer system are described.

[0022] [Example of data stored in memory] User data: Stores each user's identification information (e.g., user ID, username, etc.) and a list of game media owned. Game media data: Stores the identification information, name, category, rarity, etc. of each item (game media) used in the game. Exchangeable list: Stores a list of game media that the user wishes to exchange and other game media that can be exchanged for it. Exchange request data: Stores an example of an exchange request made by a user, the specified game content, and the request status (successful, unsuccessful, pending, etc.).

[0023] [Example of a screen displayed on the display] Exchangeable List Screen: A screen where the user can check a list of exchangeable game media. The list also includes newly added game media. Exchange request screen: A screen where a user can specify the game media they wish to exchange with another user and make an exchange request. If no specification is made, the media will be automatically added to the exchangeable list. Exchange Notification Screen: Displays notifications regarding successful, unsuccessful exchanges, or additions to the exchangeable list.

[0024] [Example of data processing by a processor] [Processing exchange requests] The processor receives an exchange request from a user and checks the information of the specified game medium. If the user does not specify the game content they wish to exchange, the processor automatically adds the game content to the exchangeable list, which allows other users to make exchange requests for the game content. For example, if the first user presses the button 414 to register on the exchangeable list without selecting the game medium they wish to exchange from the game medium included in the exchangeable list 402 on the exchange request screen 400 of Figure 4, the first game medium will be registered on the exchangeable list. Thereafter, the user presses button 416 to return to the lottery result screen 300, and then presses button 306 to receive the lottery results, and game media other than the first game media registered in the exchangeable list are granted to the first user.

[0025] [Updated exchange list] The processor updates the exchangeable list to include the newly added game content, which provides an overview of the game content that the user can exchange with other users. This list updates allow users to stay aware of exchange opportunities in real time.

[0026] Send User Notifications The processor sends a notification to the user regarding the addition of the game content to the exchangeable list, informing the user that their game content has been newly added as an exchange target. The notification may include information such as the date and time the game content was added and the reason it was added (because the user did not specify the game content they wish to exchange).

[0027] [Monitoring and processing exchange requests] The processor monitors exchange requests from other users for the game media that have been added to the exchangeable list. When an exchange request is made, the processor processes the request and executes the exchange of game content between the two users. If the exchange is successful, the processor updates the game content lists of both users and notifies both users that the exchange is complete.

[0028] Through these processes, the processor efficiently manages the game content exchange system, ensuring that game content is effectively utilized even when the user does not specify the game content they wish to exchange, allowing users to maximize the use of their game content and find new exchange opportunities.

[0029] <Third example> For the third example, an example of data stored in memory, a screen shown on a display, and processing of the data by a processor will be described.

[0030] [Example of data stored in memory] Set of game media: Information on multiple game media (e.g., characters, items, etc.) is stored as a first set. This set is subject to a lottery drawing in response to requests from a first user or a second user. User information: Information such as the identification information of the first and second users, past exchange history, currently owned game media, and candidates for exchangeable game media is stored. Exchangeable list: A list of game media that can be exchanged between the first user and the second user. It also includes information on candidate exchangeable game media designated by the second user.

[0031] [Example of a screen displayed on the display] Screens displayed on the devices of the first and second users: The game content selected by lottery is displayed. The first screen is displayed on the device of the first user, and the second screen is displayed on the device of the second user. Exchange request screen (exchangeable list (FIG. 6)): A list of exchangeable game media is displayed in response to the operation of the first user. In this example, the list also includes exchangeable game media candidates specified by the second user.

[0032] [Example of data processing by a processor] Lottery process: A game medium is selected from the first collection based on requests from the first user and the second user. Display process: The selected game media are displayed on each user's device. For example, as shown in the exchange request screen 600 of FIG. 6, the exchangeable list 602 displays exchange candidates 618 for the game media 604 that the second user has specified for the second game media. The exchange candidates for the game media may be specified based on the conditions of the game media (ID, attributes, name, etc.). Control of exchange process: The processor determines whether the game media specified by the first and second users are exchangeable, and automatically executes the exchange if the conditions are met. In particular, if the first game media specified by the first user is included in the exchangeable game media candidates specified by the second user, the processor executes the exchange directly without the second user's consent. That is, if game media 604 and game media 608 are specified and game media 608 is included in the exchange candidates 618 for game media 604, pressing exchange request 612 executes the exchange of game media 604 and game media 608 without displaying exchange approval screen 500 shown in FIG. 5.

[0033] Update of exchange results: After the exchange is completed, the information about the game media owned by the first and second users is updated. The exchanged game media is reflected in each user's ownership list.

[0034] Record of exchange: Whether the exchange is successful or not, a record of this operation may be stored in memory as part of the user information.

[0035] Automatic exchange trigger: If the first game medium designated by the first user is included in the candidate list of exchangeable game mediums designated by the second user and the first user wishes to exchange the second game medium, the processor automatically executes the exchange, thereby eliminating communication between users and additional approval procedures and realizing a smooth exchange process.

[0036] Information update: After the exchange is completed, the newly owned game content is displayed on the devices of the first and second users. In addition, the user information in memory is updated, and the newly acquired game content is added to the user's owned list.

[0037] Display update: After the exchange is completed, the displays of the first and second users' devices display the latest game media information, including the newly acquired game media and updates to the exchangeable game media list.

[0038] The above process allows users to exchange items in the game more efficiently and quickly. The automatic exchange process promotes interaction between users, and allows users to specify candidates for items they wish to exchange in advance, allowing for flexible exchange based on their preferences.

[0039] <Fourth example> Regarding the fourth example, an example of data stored in the memory of a computer system, a screen displayed on a display, and processing of the data by a processor will be described.

[0040] [Example of data stored in memory] Game media information: Examples of each game media's identification information, owner information, exchange status, exchange period, etc. are stored. Exchange list and period information: Information about the first period designated by the first user, the game media added to the exchangeable list, and the time of addition are stored. User information: Includes profile information of the first and second users, exchange history, and a list of currently owned game media.

[0041] [Example of a screen displayed on the display] Exchangeable List Screen (Figure 8): Displays the game media that the first user wishes to exchange and a list of exchangeable game media (exchangeable list). An option to specify the first period may also be displayed. Period Expiration Notification Screen: When the first period has elapsed and the game content for which the exchange was not successful is given to the first user, a notification to that effect is displayed.

[0042] [Example of data processing by a processor] Management of exchange list and period: The first user's addition of game media to the exchangeable list and the first period designation information are received and stored in memory. Monitoring for lapse of time period: The processor monitors each first time period of the game media added to the exchangeable list to detect lapse of time period. Execution of automatic granting: For game media for which the first period has elapsed and the exchange has not been completed, the processor automatically grants the game media to the first user and updates the user information. Display of notification: When automatic granting occurs due to the lapse of a period, a notification screen will be displayed on the first user's device to inform them of the results of the transaction.

[0043] [Acceptance and processing of period-specific requests] If the first user specifies a first period for the first game content, the processor accepts the specification and stores it in memory. This period is calculated from the time the game content is added to the exchange list, and if the exchange is not completed within the period, the processor automatically grants the game content to the first user.

[0044] When a first user specifies a trading period for a specific game content, that information is stored in memory and associated with the game content information. This period is used as a countdown period until automatic allocation if the trading period with another user is not successful. Period monitoring and automatic granting: When a specified first period has elapsed, the processor automatically grants the unsuccessfully exchanged game media to the first user, including updating the game media information in memory and adding the media to the first user's list of owned game media.

[0045] Notification and Feedback: When the game content is automatically granted, a notification is displayed on the first user's device indicating which game content has been granted over a certain period of time. This allows the user to immediately check the final result of the transaction and may also provide information for reviewing the transaction history.

[0046] <Fifth Example> Regarding the fifth example, an example of data stored in the memory of a computer system, a screen displayed on a display, and processing of the data by a processor will be described.

[0047] [Data stored in memory] Game media information: An example of each game media (e.g., name, type, owner, exchange status, etc.) is stored. In particular, information on whether each game media is from the first set or another set (e.g., the second set) is also included. Exchange constraint information: Constraints on exchangeability for each game medium (e.g., exchangeable only with game mediums in the first set) are stored. User information: User identification information, game media owned, game media desired to be exchanged, and exchange history are stored.

[0048] [Example of a screen displayed on the display] Game Media Selection Screen: A list of game media owned by the user and exchangeable game media is displayed. A distinction between game media from the first set and game media from other sets may also be displayed, allowing the user to decide whether to exchange. Exchange restriction explanation screen: An explanation is displayed that the game media can only be exchanged with game media from the first set, and that the game media cannot be exchanged with game media from other sets.

[0049] [Example of data processing by a processor] Determining exchangeability: When a user selects a game content they wish to exchange, the processor determines whether the game content is from the first set or another set, and updates the list of exchangeable game content based on the exchangeability constraints. Applying an exchange constraint: If the game content the user wishes to exchange is from the first set, the processor identifies game content of other users that can be exchanged for that game content. It applies a constraint that the game content can only be exchanged with game content from the first set, and controls so that the game content cannot be exchanged with game content from other sets.

[0050] Processing exchange requests: When a user takes an action indicating that they wish to exchange, the processor receives the exchange request and evaluates whether the requested exchange complies with the constraints. If the user wishes to exchange for a game medium from the first set, the processor checks whether a game medium from another user that matches the request exists, and if so, proceeds with the exchange.

[0051] Notification of non-exchangeability: If the user requests an exchange for game media from a set other than the first set, the processor notifies the user that the exchange is not possible.

[0052] Confirmation and update of exchange success: If the exchange is possible based on the constraints, the processor establishes the exchange between the two users and updates the relevant data (such as information about the game media owned by the users and the exchange history) in memory. This update may include changing the owned game media and recording the exchange history. It should be noted that the present invention is not limited to the above examples, and the above examples can be combined as appropriate.
