Japanese Patent Application Laid-Open No. 2020-044320

In addition, some of the above games include features such as mini-games where players can win items by lottery, as a way to encourage more users to enjoy gameplay. However, since mechanisms for simply winning items are already implemented in many games, there is a problem in that winning items by lottery alone is unlikely to motivate users to play the game.

Therefore, the present invention aims to provide technology that can promote users' gameplay.

An information processing device according to one aspect of the present invention has a management unit that associates objects with a user in accordance with the user's gameplay, and a control unit that determines a reward to be granted to the user based on an object selected by lottery from a plurality of objects, including the object associated with the user, in accordance with a predetermined request from the user.

The present invention provides technology that can promote user gameplay.

Embodiments of the present invention will be described with reference to the accompanying drawings. Note that in each drawing, components with the same reference numerals have the same or similar configurations.

<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 and a plurality of 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.

The game server 10 is a device that performs some of the functions required for the terminal 20 to provide a game, such as managing various information related to users and executing some of the game's processing. The game server 10 may be composed of one or more information processing devices or computers, or may be composed of a virtual server (such as a cloud server).

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 is equipped with a GPS
The mobile terminal notifies the game server 10 of its own position detected using the Global Positioning System (GPS) or the like.

<Game Overview>
Next, an overview of the game provided by the game system 1 according to this embodiment will be described. In the game provided by the game system 1, the user can progress through the game by clearing quests.

A quest is a term that refers to a task that can be completed by meeting certain predetermined conditions. Quests are also commonly referred to as explorations, challenges, events, and missions. Users who participate in a quest can complete the quest by meeting the certain conditions. Note that, as will be explained in more detail below, in this embodiment, the terms quest and mission are used in different ways, rather than in the same sense.

A deck is a term that refers to a group made up of multiple game objects. When a user performs a quest, they may create a deck using multiple game objects to perform the quest. The game objects used to create the deck may be, for example, characters or game cards owned by the user. In this embodiment, a user's execution of a game or a quest may be referred to as playing a game or playing a quest.

In the game, the user is presented with multiple tasks (hereinafter referred to as "missions") that can be completed by meeting certain conditions. A mission may be a task that can be completed by playing a quest. Examples include missions such as "Play XX quest," "Defeat at least one monster in three turns," and "Defeat all monsters in five minutes." A mission may also be a task that can be completed by clearing a quest. Examples include missions such as "Clear XX quest" and "Clear a quest with a deck containing YY characters." A mission may also be a task that is unrelated to clearing a quest. Examples include missions such as "Log in once a day," "Log in five days in a row," "Collect ZZ or more items," and "Travel more than 50 km for three consecutive days."

By completing missions while playing the game, users can obtain objects that can be used in lottery draws. The objects that can be obtained may be determined for each mission. For example, completing mission A may allow object A to be obtained, and completing mission B may allow object B to be obtained. Furthermore, multiple missions may be set for the same object. For example, the same object may be obtained by completing both mission A and mission B.

When the game server 10 receives a predetermined request from a user, it randomly selects one object from multiple objects, including an object associated with the user. The game server 10 then grants a reward to the user based on the selected object. The object associated with the user may be an object that the user owns.

Figure 2 is a diagram showing an example of a lottery method. In this embodiment, the game server 10 may perform the lottery in any manner, but for example, it may use the roulette shown in Figure 2 to determine one object from among multiple objects by lottery. In this case, the object may be a piece (which may also be called a component) to be set on the roulette.

For example, in the example shown in Figure 2, the roulette wheel is made up of eight pieces numbered 1 to 8. By spinning the roulette wheel, one of the eight pieces is determined by lottery, and a reward is awarded to the user based on the determined piece. Note that the example shown in Figure 2 is just one example, and the roulette wheel of this embodiment is not limited to this. For example, the angle of each piece is not limited to 45 degrees, and may be any angle.

<Hardware configuration>
3 is a diagram showing an example of the hardware configuration of the game server 10 and the terminal 20. The game server 10 and the terminal 20 include a processor 11 such as a CPU (Central Processing Unit) or a GPU (Graphical Processing Unit), a storage device 12 such as a memory, an HDD (Hard Disk Drive) and/or an SSD (Solid State Drive), a communication IF for wired or wireless communication,
The system includes an interface 13, an input device 14 that accepts input operations, and an output device 15 that outputs 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.

<Function block configuration>
(game server)
FIG. 4 is a diagram showing an example of the functional block configuration of the game server 10. The game server 10 includes a storage unit 100, a management unit 110, and a control unit 111. The storage unit 100 can be realized using a storage unit 12 provided in the game server 10. The control unit 111 can be realized by the processor 11 of the game server 10 executing a program stored in the storage unit 12. The program can be stored in a storage medium. The storage medium storing the program may be a non-transitory computer-readable medium. The non-transitory storage medium is not particularly limited, and may be, for example, a storage medium such as a USB memory or a CD-ROM.

The storage unit 100 stores game data necessary for the game server 10 to run the game. The game data includes various databases.

The management unit 110 performs a process of associating an object with a user in accordance with the user's gameplay. The management unit 110 may associate an object with a user by recording information indicating the association between the user and the object in a database stored in the storage unit 100. The process of associating an object with a user may involve assigning the object to the user.

The control unit 111 performs various processes necessary to execute the game. In addition, the control unit 111 determines a reward to be granted to a user based on an object drawn by lottery from multiple objects including an object associated with the user (e.g., an object owned by the user) in response to a predetermined request from the user. The predetermined request may be, for example, a request to hold a lottery. Furthermore, the multiple objects may further include an object specified by the user among the objects associated with the user. Furthermore, the control unit 111 may draw an object by lottery from multiple objects associated with the user, including an object specified by the user.

Furthermore, each of the multiple objects may be associated with a reward, and the control unit 111 may grant the user the reward associated with the selected object. For example, assume that item A is associated with object A as a reward, and item B is associated with object B as a reward. If object A is determined by lottery, the control unit 111 may grant item A associated with object A as a reward to the user. The reward may include, for example, game value and game objects. Furthermore, game value is a value that can be expressed numerically, and may include, for example, points, points, and scores. Game objects may include, for example, items, characters, game cards, and the like.

The control unit 111 also displays various screens for the game on the display of the terminal 20. For example, the control unit 111 may display a screen showing how a lottery is being drawn (for example, how a roulette wheel is spinning) on the display of the terminal 20.

(Terminal)
FIG. 5 is a diagram showing an example of a functional block configuration of the terminal 20. The terminal 20 includes a storage unit 200, a communication unit 201, a UI (User Interface) unit 202, and a control unit 203. The storage unit 200 can be realized using the storage unit 12 provided in the terminal 20. The communication unit 201, the UI unit 202, and the control unit 203 can be realized by the processor 11 of the terminal 20 executing a program stored in the storage unit 12. The program can be stored in a storage medium. The storage medium storing the program may be a computer-readable non-transitory storage medium. The non-transitory storage medium is not particularly limited, and may be, for example, a storage medium such as a USB memory or a CD-ROM.

The memory unit 200 stores the game data necessary for the control unit 203 to execute the game. The game data includes image data of objects, game scenarios, etc.

The communication unit 201 has the function of performing various communications with the game server 10 using the communication IF 13.

The UI unit 202 has the function of accepting various inputs from the user and displaying various game screens on the display. The UI unit 202 also displays game screens on the output device 15 (display) of the terminal 20 in accordance with instructions from the game server 10.

The control unit 203 cooperates with the game server 10 to provide various functions necessary to execute the game. For example, the control unit 203 provides functions such as obtaining various information (icon image data, text data, etc.) from the game server 10 for drawing on the game screen.

When the functional block configuration described above is included in the game server 10, all or part of the management unit 110, control unit 111, and display control unit 112 may be configured to be provided in the control unit 203 of the terminal 20. In other words, the various processes related to this embodiment may be executed by the game server 10, the terminal 20, or the game server 10 and the terminal 20 in cooperation with each other.

<Processing procedure>
Next, a description will be given of specific processing procedures performed by the game system 1. The storage unit 100 of the game server 10 stores a user management DB (Data Base) 100a that manages game data of each user.

In the following explanation, the game server 10 will use a roulette to randomly select one object from among multiple objects. This object will be a "piece" to be set on the roulette. Associating an object with a user will mean giving the object to the user. An object associated with a user will be an object that the user owns.

Figure 6 shows an example of user management DB 100a. User management DB 100a manages various data related to users who play the game. For example, user management DB 100a stores, in association with each other, a user ID that uniquely identifies the user, a nickname used as a username in the game, a friend registration list that indicates other users with whom the user has a friendship, location information that indicates the location of the device 20 used by the user, various parameters such as the user's experience points, rank, stamina, and number of points held by the user, and the type and number of pieces held by the user.

Figure 7 is a flowchart showing an example of the processing steps performed by the game server 10 when granting pieces.

In step S10, the control unit 111 executes the game in response to the user's instructions. Also, in response to the user's instructions, it executes the quest selected by the user.

In step S11, if the user meets the piece acquisition conditions, the control unit 111 grants pieces to the user. The management unit 110 records information about the pieces granted to the user (type and number of pieces) in the "Owned Pieces" field of the user management DB 100a.

Figure 8 is a diagram showing an example of a piece. "Piece Name" indicates the name of the piece that uniquely identifies the piece. The piece name may be a piece ID or piece identifier, as long as it is information that can uniquely identify the piece. "Piece Acquisition Condition" indicates the content of the mission that the user must complete to acquire a piece. For example, if a user logs in to the game continuously for Z days, the user will be awarded piece D. Similarly, if the user defeats five enemies in one quest, piece E will be awarded. "Piece Angle" indicates the angle that a piece occupies on the roulette wheel when set on the roulette. Note that since the roulette rotates 360 degrees, the larger the piece angle, the more likely the piece is to win. For example, if the piece angle is 45 degrees, the probability of that piece being selected is 45/360 x 100 = 12.5%. In other words, it can be said that each of the multiple pieces is associated with a selection probability. Note that in this embodiment, the piece angle of each piece may be the same (e.g., 45 degrees). Also, in the following explanation, piece angle may be interpreted as lottery probability.

"Reward" refers to the reward that will be awarded to the user if that piece is selected as a result of the lottery. In other words, each of the multiple pieces is associated with a reward. For example, if piece A is selected by spinning the roulette, 50 items A will be awarded to the user.

Figure 9 is a diagram showing an example of piece settings. The letters A to E in Figure 9 correspond to the piece names in Figure 8. Pieces A, B, C, and D are set on the roulette R10 in Figure 9. The piece angle of piece D is 90 degrees, which is twice the piece angle of pieces A, B, and C. Therefore, piece D occupies an area twice the size of pieces A, B, and C.

Here, some pieces (objects) may be associated with multiple types of rewards, and each of the multiple rewards may be associated with a piece angle (lottery probability). Special pieces (predetermined objects) may be included. The piece angles associated with each reward may be different for each reward, or may be the same. For example, in the case of piece E shown in FIG. 8 , 500 items A are associated with a piece angle of 5 degrees, and 10 items A are associated with a piece angle of 40 degrees. This indicates that when the roulette is spun, there is a 5/360×100=1.39% probability of receiving 500 items A, and a 40/360×100=11.11% probability of receiving 10 items A. Piece E set on the roulette is shown as roulette R11 in FIG. 9 . In roulette R11, when the roulette stops on the narrower of the two areas of piece E, the user is awarded 500 items A, and when the roulette stops on the wider area, the user is awarded 10 items A.

Figure 10 is a flowchart showing an example of the processing steps when the game server 10 conducts a lottery.

In step S20, the control unit 111 accepts the creation of a roulette from the user. More specifically, the control unit 111 accepts the selection of multiple pieces to be set on the roulette from the user. For example, the control unit 111 references the user management DB 100a to obtain the pieces owned by the user, and accepts from the user the selection of pieces to be set on the roulette from among the obtained pieces.

In step S21, when the control unit 111 receives an instruction from the user to conduct a lottery, it selects one or more pieces from the plurality of pieces based on the selection probability associated with each of the plurality of pieces (determines one or more pieces by lottery). The control unit 111 may select one piece from the plurality of pieces, or may select two or more pieces from the plurality of pieces. The control unit 111 may select pieces by any method, but may select pieces by the following method, for example.

1: Output a random number X between 0 and 1; 2: Calculate a value Y by multiplying the random number X by 360; 3: Consider Y as the clockwise angle from the starting direction of the roulette (the direction of angle 0), and determine the piece located in the direction of angle Y as the drawn piece. For example, assume that the starting direction of the roulette R10 shown in FIG. 9 is 0 o'clock. If 0≦Y<45, piece A in the upper right corner is drawn; if 45≦Y<90, piece B in the upper right corner is drawn; if 90≦Y<135, piece A (upper side) in the lower right corner is drawn; and if 135≦Y<180, piece A (lower side) in the lower right corner is drawn.

Furthermore, the control unit 111 may create a video of the lottery results obtained by the above method, for example, by generating a video of a spinning roulette wheel stopping to select a piece, and displaying this video on the terminal 20, thereby creating the illusion of the lottery being drawn. Return to Figure 10 to continue the explanation.

In step S22, the control unit 111 grants the user a reward associated with the drawn piece. If the control unit 111 draws a special piece (predetermined object) from multiple pieces in the processing procedure of step S21, the control unit 111 may further draw at least one reward from multiple types of rewards associated with the special piece in accordance with the drawing probability associated with each of the multiple rewards. The control unit 111 may also grant the user at least one of the drawn rewards.

[Conditions for obtaining pieces]
9, the management unit 110 may assign (associate) a specific piece to a user when a specific play condition is satisfied by the user's game play and the user has completed a specific mission (task) by playing the game. Furthermore, if the specific play condition is not satisfied, the management unit 110 may not assign (associate) a specific object to the user even if the user has completed a specific mission.

The specific play conditions may be met, for example, when the user possesses a predetermined number of pieces or more, or when the user possesses a predetermined number of different types of pieces. A specific mission may be a mission that can only be played when a specific play condition is met. A specific piece may be the special piece mentioned above, or a piece that is awarded as a reward for a predetermined number of game objects or a piece that is awarded as a reward for a game object with a parameter such as rarity that is predetermined or more. Rarity indicates the degree to which a game object can be obtained in the game; the higher the value, the lower the possibility of obtaining the object.

For example, if the number of pieces owned by a user is equal to or greater than a predetermined number, the control unit 111 may allow the user to play a specific mission, and may grant the user a special piece if the user completes the specific mission. Also, if the number of pieces owned by a user is less than a predetermined number, the control unit 111 may not grant the user a special piece even if the user completes the specific mission. This makes it possible to motivate the user to play the game until a specific play condition is met.

[Conditions for conducting the lottery]
(Condition Example 1)
The control unit 111 may be configured to accept designation of two or more objects from a user when pieces (objects associated with the user) owned by the user satisfy a predetermined condition. The predetermined condition may be that the user owns a predetermined number of pieces or more. In other words, the control unit 111 may be configured to be able to accept a request (a predetermined request) from the user to hold a lottery when the user owns a predetermined number of pieces or more.

There is no particular limit to the predetermined number, but it may be the minimum number of pieces required to set pieces on the roulette. If the angle of each piece is a fixed value, the minimum number of pieces can be calculated by dividing 360 degrees by the piece angle. For example, if the piece angle is 45 degrees, the minimum number of pieces is 8.

Also, if the piece angles of each piece are different, the minimum number of pieces may be the same as the number of pieces in the combination with the fewest number of pieces among the combinations of pieces owned by the user that add up to 360 degrees. For example, if a user owns 10 45-degree pieces and 2 90-degree pieces, the combination with a total angle of 360 degrees is 2 90-degree pieces and 4 45-degree pieces. Therefore, the minimum number of pieces in this case may be 6.

(Condition Example 2)
The control unit 111 may be configured to accept a request (predetermined request) from a user to hold a lottery when the total value of parameters associated with each piece specified by the user satisfies a predetermined parameter condition. Here, the pieces specified by the user may be pieces set on the roulette at the user's instruction. Furthermore, the parameters may be piece angles. Furthermore, the predetermined parameter condition (which may be referred to as a first parameter condition) may be that the sum of the piece angles of the pieces set on the roulette is 360 degrees. That is, the control unit 111 may accept a request from a user to hold a lottery when the sum of the piece angles of the pieces set on the roulette by the user is 360 degrees. Furthermore, the control unit 111 may not accept a request from a user to hold a lottery when the sum of the piece angles of the pieces set on the roulette is not 360 degrees (for example, when the sum is 315 degrees and one more 45-degree piece needs to be set). This prevents a lottery from being held before the user has finished setting the pieces on the roulette.

The control unit 111 may preset pieces on the roulette in advance and accept from the user a request to exchange all or some of the preset pieces for pieces owned by the user. The control unit 111 may also accept a request to hold a lottery from the user regardless of whether all or some of the preset pieces have been exchanged. In other words, the roulette will contain a mixture of preset pieces and pieces set by the user. The control unit 111 may also accept a request to hold a lottery from the user even in this state. In other words, the control unit 111 may be able to accept a request to hold a lottery (a predetermined request) from the user regardless of whether the total value of parameters (e.g., piece angles) associated with each of the pieces specified by the user (pieces set by the user on the roulette, excluding preset pieces) satisfies a predetermined parameter condition (e.g., the total piece angles being 360 degrees).

The control unit 111 may also be configured to accept a request from the user to conduct a lottery when the user exchanges a predetermined number of pieces from among the pieces preset on the roulette.

[Changes to lottery odds]
When a predetermined play condition is satisfied by the user's game play, the control unit 111 may be able to change the selection conditions, which indicate the conditions for selecting one or more pieces from the plurality of pieces, based on a user instruction. In other words, the selection conditions for the pieces may not be fixed for each piece but may be changeable by a user instruction. Here, the selection conditions may include the selection probability described above. For example, the control unit 111 may accept, from the user, a change in the selection probability associated with each of the plurality of objects as the selection condition. For example, the control unit 111 may accept a change in the piece angle of the pieces to any angle or an angle of a predetermined pattern (e.g., an angle that is divisible by 360 degrees, such as 45 degrees, 60 degrees, 90 degrees, 120 degrees, or 180 degrees).

"When a predetermined play condition is met" may mean, for example, when a predetermined number of pieces or more are awarded to a user. In other words, when a predetermined number of pieces are awarded (associated) to a user as a predetermined play condition through the user's game play, the control unit 111 may be able to change the lottery conditions based on instructions from the user.

Furthermore, "when a specified play condition is met" may mean, for example, that the user has a specified number of pieces, that the user has entered the lottery a specified number of times, that the user has completed a specified quest (such as a limited-time quest or an event quest), that the user has completed a specified number of quests, or that the user has logged in for a specified number of consecutive days. Since the user must meet specified play conditions to increase the probability of winning pieces, this will encourage the user to play the game.

<Screen display example>
FIG. 11 is a diagram showing an example of a game screen. In the example of FIG. 11, it is assumed that the piece angles of all pieces are 45 degrees. The piece selection screen M100 is a screen that accepts the selection of a piece to be set on the roulette. When a piece is selected on the piece selection screen M100 and the confirm button is pressed, the control unit 111 displays the roulette display screen M200. On the roulette display screen M200, the control unit 111 may display the piece selected on the piece selection screen M100 set at a random position on the roulette, or may allow the user to arbitrarily select a position to set the piece selected on the piece selection screen M100. The control unit 111 may also accept an instruction from the user to swap the positions of the pieces. For example, the control unit 111 may swap the piece set at position H and the piece set at position C on the roulette display screen M200 in response to a user instruction.

When the button to spin the roulette is pressed on the roulette display screen M200, the control unit 111 displays the lottery result screen M201. The control unit 111 may display the pieces that have been drawn and the pieces that have not been drawn in a manner that allows them to be distinguished. More specifically, the control unit 111 may display the piece that has been drawn (the piece in the upper right corner in the example of Figure 11) on the lottery result screen M201 in a manner that is different from the pieces that have not been drawn.

[Screen display variation 1]
When the total value of parameters associated with each piece specified by a user does not satisfy a predetermined parameter condition, the control unit 111 may distinguishably display, among the objects owned by the user, objects whose total value satisfies a predetermined parameter condition (which may be referred to as a first parameter condition) when additionally specified by the user, and objects whose total value does not satisfy the predetermined parameter condition even when additionally specified by the user. As with "Condition Example 2" in the above-described "Conditions for Executing a Lottery," the pieces specified by the user may be pieces set on the roulette by the user. The parameters may also be piece angles. The predetermined parameter condition (first parameter condition) may be that the sum of the piece angles of the pieces set on the roulette is 360 degrees. In other words, when the sum of the piece angles of the pieces set on the roulette by the user is less than 360 degrees, the control unit 111 may display, in different ways, pieces whose total piece angle becomes 360 degrees when set on the roulette and pieces whose total piece angle does not become 360 degrees when set on the roulette. This allows the user to easily identify pieces that, when set on the roulette, will result in a total of 360 degrees in piece angles.

The specified parameter condition (which may be referred to as the second parameter condition) may be that the sum of the piece angles of the pieces set on the roulette is 360 degrees or less. In other words, when the sum of the piece angles of the pieces set on the roulette by the user is 360 degrees or less, the control unit 111 may display, in different ways, pieces whose sum of piece angles is 360 degrees or less even when set on the roulette and pieces whose sum of piece angles is not 360 degrees or less when set on the roulette (i.e., pieces whose sum of piece angles exceeds 360 degrees).

Figure 12 is a diagram showing an example of a game screen display. In the example of Figure 12, it is assumed that the piece angles of each piece are allowed to differ. On the piece selection screen M300, no pieces are set in the 90-degree areas displayed as unselected. In this state, pieces A through F can all be set, so the control unit 111 displays pieces A through F in a selectable manner. On the other hand, on the piece selection screen M301, the areas displayed as unselected are 45 degrees, so pieces D and F, which have piece angles exceeding 45 degrees, cannot be set on the roulette. Therefore, the control unit 111 displays pieces D and F in a different manner from pieces A through C and E. This allows the user to easily distinguish between pieces that can be set on the roulette and pieces that cannot be set.

[Screen display variation 2]
The control unit 111 may notify the user of information about pieces not owned by the user (objects not associated with the user) that satisfy a predetermined condition, based on pieces designated by the user among pieces owned by the user (objects associated with the user). Information about pieces that satisfy the predetermined condition may be, for example, information about pieces that have attributes corresponding to pieces designated by the user. Furthermore, the pieces designated by the user may be pieces that the user has set on the roulette. In other words, the control unit 111 may display, on the screen of the terminal 20, information about pieces not owned by the user that have attributes corresponding to pieces set on the roulette by the user. The information may be, for example, information indicating the content of a mission from which the pieces can be obtained.

Furthermore, "pieces having attributes corresponding to pieces set on the roulette by the user" may refer to pieces in which the game objects awarded as a reward are the same type or identical to the pieces set on the roulette, or pieces in which the game objects awarded as a reward are the same as the pieces set on the roulette and the number of game objects awarded is greater than the number of game objects awarded by the pieces set on the roulette. For example, if "piece A," which awards 50 units of item A as a reward, is set on the roulette, the control unit 111 may display information about "piece B," which awards 200 units of item A as a reward, on the screen of the terminal 20. Alternatively, "pieces having attributes corresponding to pieces set on the roulette by the user" may refer to pieces that have a predetermined relationship with the pieces set on the roulette, or pieces that can be obtained by completing the same type or identical mission as the pieces set on the roulette. This allows the user to easily obtain information about pieces that the user does not own but that meet predetermined conditions.

[Screen display variation 2]
In the game, the period during which a mission can be challenged (i.e., the period during which pieces can be acquired) may be limited. The control unit 111 may display information indicating that the period during which a mission can be challenged (the period during which a mission can be completed) has ended on the screen of the user's terminal 20, after a predetermined timing before the end of the period during which a mission can be challenged.

<Summary>
