Description

The present invention relates to an information processing device, control program, and control method.

In recent years, communication terminals having a touch panel display such as smart phones have become popular, and each user owns his/her own communication terminal. Under such circumstances, services that provide users with community-type services on the Internet, that is, social networking services (hereinafter referred to as "SNS") are known. Online games (social games) are provided to users as one of such SNSs.

In an online game, objects such as characters and items appearing in the game may be provided by lottery (see, for example, Patent Document 1). In a lottery, winning probability is generally set for each object, and when a user requests a lottery, an object to be provided to the user is selected based on the set winning probability. Objects for which a low probability of winning is set are often designed so that the rarity, that is, the degree of rarity, is high, and the game can proceed advantageously accordingly. Therefore, users often aim to obtain rare cards in the game. Depending on the game, lotteries may be held consecutively in order to efficiently obtain objects with high rarity with low odds of winning.

JP 2013-247977 A

As described above, in online games, winning probabilities are generally set for each object. Object lottery processing is performed for each user from a uniform population provided for each user, so the lottery result of one's own lottery is not affected by the lottery results of other users.

The present invention provides a technique for improving user's expectation value for winning an object that has not yet been drawn in a lottery in which a limited number of remaining lottery objects is shared and managed by a plurality of users.

An information processing apparatus according to an aspect of the present invention includes a determination unit that determines one target from a plurality of targets in response to a lottery request from a user and provides the determined target to the user; any of the above-mentioned objects from a shared group, which is a group formed from one or more predetermined objects and wherein the remaining number of the objects in the group is shared and managed by a plurality of users and an updating unit that, if determined, reduces the remaining number of said objects in said shared group.

ADVANTAGE OF THE INVENTION According to one aspect of the present invention, in a lottery in which a limited number of remaining lottery targets is shared and managed by a plurality of users, it is possible to improve the user's expectation value for winning an object that has not yet been selected. .

It is a flow chart of lottery processing (S10) in Example 1 of this embodiment. It is a flow chart of lottery processing (S10) in Example 2 of this embodiment. It is an example of a configuration block diagram of a hardware environment of a computer that executes a program according to the present embodiment.

FIG. 1 is a diagram showing an example of an information processing apparatus according to this embodiment. The information processing device 1 includes a determination unit 2 and an update unit 3 . An example of the information processing device 1 is a server 15, which will be described later.

The determination unit 2 determines one target from a plurality of targets in response to a lottery request from the user, and provides the determined target to the user. Examples of the determining unit 2 include a lottery unit 34 and a providing unit 36, which will be described later.

The updating unit 3 selects any of If any target is determined, decrease the remaining number of targets in the shared group. An example of the update unit 3 is a box management unit 35, which will be described later. Here, the shared group is a shared box managed by the shared box management database 43 as described later.

By constructing in this way, in a lottery where a limited remaining number of lottery objects is shared and managed by a plurality of users, it is possible to improve the user's expectation value for winning an object that has not yet been lottered.

The determination unit 2 may determine any one of the shared group and the individual user groups independently managed for each of the plurality of users. The user group is a user box managed by the user box management database 44, as will be described later. The shared group includes many lottery targets that are rarer than the lottery targets included in the user-specific groups. Also, the shared group and the user-specific group may be configured so that the lottery targets are different, and the shared group may include the lottery target with higher rarity than the user-specific group. In other words, the shared group includes rare game elements (characters and items) that users want more than the user-specific groups.

With this configuration, the user can draw a lottery from the shared group and the group for each user. Therefore, when the lottery is drawn from the shared group, the user's expectation of winning the target that has not yet been drawn. value can be improved.

The determination unit 2 may determine one of the shared group and the user group based on the first probability set for the shared group and the second probability set for the user group. Then, when any target is determined from the shared group, the determining unit 2 may decrease the first probability and increase the second probability.

By configuring in this way, it is possible to reduce the chance that the remaining number of lottery targets decreases from the shared table.

The determining unit 2 may determine a target with higher rarity in the shared group as the remaining number of targets in the shared group decreases.

By configuring in this way, as the remaining number of targets in the shared group decreases, the expected value of obtaining a target with a higher rarity increases, and the desire to continue the lottery can be maintained.

If the number of remaining lottery targets in the shared group is equal to or less than a predetermined number, and one of the targets is determined and provided, the determination unit 2 may provide the privilege in addition to the determined targets. Here, the privilege may be, for example, a character or item that appears in the game, an object such as in-game currency, a predetermined effect for advancing the game advantageously, or a predetermined music. Alternatively, it may be a coupon ticket or the like.

By configuring in this way, for example, when the lottery is drawn last, a privilege can be provided in addition to the winning object, so that the user's expectation value can be further increased.

The predetermined number or less represents, for example, "1" or less, and a privilege may be provided in addition to the last drawn object in the shared group. As an example, by giving the user a privilege such as a game element (item or character) with a high rarity level as a privilege at the end, the user can actively draw a lottery for the last lottery target.

The determination unit 2 may vary the number of attempts to successively determine any target in response to a request from the user, according to the remaining number of targets.

By configuring in this way, it is possible to change the number of consecutive lotteries that can be performed according to the remaining number of objects. Therefore, for example, when the final lottery is performed, in the case of providing benefits in addition to the winning object, if the remaining number of objects is 5, the number of consecutive lotteries can be suppressed to 4 or less, so that the continuous lottery Attempts in processing can be adjusted so that no perks are earned.

The updating unit 3 may reduce the remaining number of targets in the user-specific group when any target is determined from the user-specific group. At this time, when there are no remaining objects in the user-specific group, the determining unit 2 resets the objects in the user-specific group to the initial state (executes processing for returning the remaining number to the initial value), and You may make it compare and raise the 1st probability that a shared group will be drawn.

By configuring in this way, the more lotteries are performed by users, the more lottery objects can be obtained from the shared box, so that the more rare lottery objects (game elements) can be obtained.

The determining unit 2 may determine one of the targets from the shared group at least once when the user makes a request to determine one of the targets in succession a plurality of times.

By configuring in this way, it is possible to improve the motivation to select the continuous lottery.

Thereby, the user can operate the application program by performing an input operation on the operation display unit 13 of the user terminal 12 . In the present embodiment, as an example, game application software (hereinafter referred to as “game application software”) that allows online games to be played by accessing a cloud server or the like via communication is installed on the user terminal 12. shall be

The user can access the server 15 from the user terminal 12 by activating this game application software on the user terminal 12 . When the user terminal 12 accesses the server 15, for example, input of a pre-registered login user ID may be required.

When the game application software installed in the user terminal 12 is activated, the screen 14 of the user terminal 12 displays a later-described graphical user interface (GUI) screen. The GUI screen displays a screen for registering photographs and moving images of children and family members in the server 15 and viewing the registered photographs and moving images.

A user can access the server 15 by activating the game application software installed in the user terminal 12 and operating the GUI screen. The user can then operate the GUI screen to upload photos and moving images held in the user terminal 12 to the server 15 .

The server 15 is an information processing device that manages game applications installed in the terminal device 12 . For example, the server 15 manages information about users who use game applications (for example, content of play, status information of characters being played, point information, etc.), and information about billing. The server 15 may be a server system configured by one or more physical information processing devices, or may be a virtual server system configured by one or more virtual server devices.

The server 15 may be a server system configured by one or more physical information processing devices, or may be a virtual server system configured by one or more virtual server devices.

FIG. 3 is a diagram showing an example of functional blocks of the game system 11 in this embodiment. Functions of the user terminal 12 and the server 15 will be described below.

The user terminal 12 includes an operation display section 13 , a communication section 21 , a control section 22 and a storage section 23 . The communication unit 21 is an interface that enables communication with devices connected to the communication network 16 . Here, the communication section 21 communicates with the server 15 via the communication network 16 .

The operation display unit 13 is a touch panel display that enables input and display by a user's input operation. In this embodiment, a touch panel display is used as an example, but the present invention is not limited to this, and the input section and the display section may be independent of each other.

The control unit 22 controls the operation of the user terminal 12 as a whole. The control unit 22 controls the display state of the screen 14 based on user interface (UI) data of the game application program 24 stored in the storage unit 23 .

The storage unit 23 stores the installed game application program 24, game element data 25, various data, and the like. Here, data includes not only status information and character data, but also graphical data. The game element data 25 includes background data used in the game, object data such as characters and items, numerical data such as parameters, and the like.

The server 15 includes a communication section 31 , a control section 32 and a storage section 41 . The communication unit 31 is an interface that enables communication with devices connected to the communication network 16 . The communication unit 31 communicates with the user terminal 12 via the communication network 16 .

The control unit 32 controls the operation of the server 15 as a whole. At the same time, the control unit 32 performs control such as executing processing in response to a request from the user terminal 12 and returning execution results to the user terminal 12 . The control unit 32 functions as a request acquisition unit 33, a lottery unit 34, a box management unit 35, and a provision unit 36 by executing the application program according to this embodiment.

The request acquisition unit 33 acquires a request from the user terminal 12 . In this embodiment, an example of a request is a request to draw one of the lottery targets by lottery from a lottery box containing the lottery targets. There is a continuous lottery request that requests lotteries in succession (more than once).

Based on a request from the user terminal 12, the lottery unit 34 determines one of the lottery objects as the winning object from the lottery boxes containing the lottery objects. Here, lottery boxes include individual boxes and shared boxes. An individual box is a uniform population of objects to be drawn by lottery provided for each user, and is specifically managed by the user-specific box management database 44 . A shared box is a population of objects to be selected by lottery shared by all users, and is specifically managed by the shared box management database 43 . Hereinafter, the database will be referred to as "DB".

Further, the lottery section 34 not only determines one of the lottery targets from the lottery box as a winning target, but also reads information specifying the privilege target object from the privilege management DB 45 based on a predetermined rule.

When any lottery object is determined as a winning object from the lottery box, the box management unit 35 reduces the lottery object from the lottery box. More specifically, when any lottery target is determined as a winning target from the shared box, the box management unit 35 reduces the winning target from the shared box (shared box management DB 43) and selects one from the individual box. When the lottery target is determined as the winning target, the winning target is reduced from the individual box (user-specific box management DB 44). The box management unit 35 adds information on the winning objects (objects removed from the lottery box) to the user management DB 42 .

Also, the box management unit 35 acquires the total number of remaining objects in the shared box from the shared box management DB 43 in response to an inquiry from the user terminal 12 .

The providing unit 36 responds to the inquiring user terminal 12 with the total remaining number of objects in the shared box. Also, the providing unit 36 provides the user terminal 12 with the lottery target selected as the winning result via the communication unit 31 . When the communication unit 31 receives the lottery result information (the lottery target selected as the winning result) from the providing unit 36 , the communication unit 31 transmits the lottery result information to the user terminal 12 . Then, the received lottery result information is displayed on the screen 14 of the user terminal 12 .

The storage unit 41 contains a program according to the present embodiment and data used for the program. The storage unit 41 also includes a user-owned object management DB 42 , a shared box management DB 43 , a user-specific box management DB 44 , and a privilege management DB 45 .

The user-owned object management DB 42 is a database for managing objects owned by users. The shared box management DB 43 is a database that manages the remaining number of lottery target objects in the shared box shared by all users who play the game system 11 . The user-by-user box management DB 44 is a database for managing uniform objects to be drawn by lottery provided for each user. The privilege management DB 45 is a database for managing objects as privileges.

FIG. 4 is a diagram showing an example data structure of a database managed by the server 15 in this embodiment. Below, each record of the user-owned object management DB 42 may be referred to as user-owned object information. Each record of the shared box management DB 43 may be referred to as shared box information. Each record of the user-specific box management DB 44 may be referred to as user-specific box information. Each record of privilege management DB45 may be called privilege information. Note that the data structure of the database in FIG. 4 is a conceptual structural example for convenience of explanation, and is not limited to this.

The user-owned object management DB 42 includes data items such as "user ID", "object 1", "object 2", and so on. The item “user ID” stores information (user ID) that identifies the user. The items "object 1", "object 2", .

The shared box management DB 43 includes data items of "object ID", "rarity", "initial setting number", "winning number", "remaining number", and "winning probability". The item "object ID" stores information (object ID) that identifies an object. The item “rarity” stores rank information indicating the rarity of the object. In this example, rarity increases in the order of C<B<A<S. The item "initial setting number" stores the number of objects initially set in the shared box. The item "number of wins" stores the number of times the object has been won by lottery. The item "remaining number" stores the remaining number of objects in the shared box, that is, the value obtained by subtracting the winning number from the initial setting number. The item "winning probability" stores the probability of winning each object (lottery target) included in the shared box when the shared box is selected with the first probability in the lottery. For example, in the example of FIG. 4B, the shared box includes an object with object ID=A0001, an object with object ID=A0002, and an object with object ID=A0003. The remaining number of objects with object ID=A0001 is 8, the remaining number of objects with object ID=A0002 is 10, and the remaining number of objects with object ID=A0003 is 1. Therefore, the remaining number of objects in the shared box is 8+10+1=19. Therefore, the winning probability of the object with object ID=A0001 is (8/19)×100≈42%. The winning probability of the object with object ID=A0002 is (10/19)×100≈53%. The winning probability of the object with object ID=A0003 is (1/19)×100≈5%.

The user-specific box management DB 44 includes data items of "user ID", "object ID", "rarity", "initial setting number", "winning number", "remaining number", and "winning probability". The item “user ID” stores information (user ID) that identifies the user. The item "object ID" stores information (object ID) that identifies an object. The item “rarity” stores rank information indicating the rarity of the object. In this example, rarity increases in the order of C<B<A<S. The item "initial setting number" stores the number of objects initially set in the shared box. The item "number of wins" stores the number of times the object has been won by lottery. The item "remaining number" stores the remaining number of objects in the shared box, that is, the value obtained by subtracting the winning number from the initial setting number. The item "winning probability" stores the probability of winning each object (lottery target) included in the user-specific box when the user-specific box is selected with the second probability in the lottery. For example, in the example of FIG. 4C, the user-specific box of the user with user ID=user001 includes an object with object ID=A0008, an object with object ID=A0009, and an object with object ID=A0010. . The remaining number of objects with object ID=A0008 is 1, the remaining number of objects with object ID=A0009 is 11, and the remaining number of objects with object ID=A0010 is 10. Therefore, the remaining number of objects in the user-specific box is 1+11+10=22. Therefore, the winning probability of the object with object ID=A0008 is (1/22)×100≈5%. The winning probability of the object with object ID=A0009 is (11/22)×100=50%. The winning probability of the object with object ID=A0010 is (10/22)×100≈45%.

The privilege management DB 45 includes data items of "privilege ID" and "rarity". The item "privilege ID" stores information (object ID) specifying an object set as a privilege. The item “rarity” stores rank information indicating the rarity of an object set as a privilege.

FIG. 5 is a diagram showing an example of a lottery screen (before the lottery) in this embodiment. When the user activates the game application program 24 on the user terminal 12, a lottery screen 51 is displayed.

The lottery screen 51 includes a lottery box display field 52, a "single lottery" button 53, a "continuous lottery" button 54, and a remaining number display field 55 for all objects in the shared box. In the lottery box display column 52, the pattern of the lottery box is displayed. When the "single lottery" button 53 is tapped, the lottery is performed only once. When the "continuous lottery" button 54 is tapped, the lottery is continuously performed for a predetermined number of times (2 or more). The remaining total number of objects in the shared box display column 55 displays the remaining number of all objects in the shared box.

FIG. 6 is a diagram showing an example of the lottery screen (after the lottery) in this embodiment. For example, in FIG. 5, when the "single lottery" button 53 is tapped, a lottery is performed, and after the effect of ejecting the winning object from the lottery box 52, the state of FIG. 6 is entered.

A lottery screen 51 in FIG. 6 is information in which a winning object 61 is overlapped with that in FIG. The drawing of the object and its rarity are displayed on the winning object 61 .

FIG. 7 is a diagram showing an example of a lottery screen (in the case of prize winning) in the present embodiment. FIG. 7A shows an example of the lottery screen before drawing the remaining one object. FIG. 7B shows an example of a lottery screen when the privilege is won by drawing the remaining one object.

For example, when a lottery is held using a shared box, it is assumed that the shared box contains only a finite number of objects. Therefore, for example, a user who draws one remaining object may be provided with an additional object (for example, an object with a high rarity) as a privilege.

For example, on the lottery screen 51 of FIG. 7A, "1" is displayed as the total remaining number of objects in the shared box. In this state, when the "single lottery" button 53 is tapped, a lottery is performed. Then, as shown in FIG. 7(B), an effect is produced in which the last object 61 in the shared box is produced from the lottery box 52, and further, an effect is produced in which an object 71 of rarity S is provided as a specific object. At this time, the total remaining number of objects in the shared box is displayed as "0".

FIG. 8 is a sequence diagram of the entire game system in this embodiment. First, the user starts the game application program 24 installed in the user terminal 12 . Then, the user terminal 12 makes a connection request to the server 15 (S1). The server 15 responds with connection permission in response to the connection request (S2), and the connection between the user terminal 12 and the server 15 is completed.

The user operates the operation display unit 13 to display the lottery screen 51 on the screen 14 (S3). Based on the game application program 24, the user terminal 12 inquires of the server 15 about the total remaining number of objects in the shared box (S4).

In response to the inquiry from the user terminal 12, the server 15 performs processing for obtaining the remaining number of shared boxes (S5). That is, in response to an inquiry from the user terminal 12 , the server 15 acquires the total remaining number of shared box objects from the shared box management DB 43 shared by all users playing the game system 11 . Details of the processing of S5 will be described later.

The server 15 transmits the total number of remaining objects in the shared box acquired from the shared box management DB 43 as the inquiry result to the user terminal 12 that made the inquiry (S6).

Upon receiving the inquiry result from the server 15, the user terminal 12 reflects the remaining number of all objects in the shared box in the remaining number display field 55 of the lottery screen 51 based on the inquiry result (S7).

The user taps the "single lottery" button 53 or the "continuous lottery" button 54 on the lottery screen 51 (S8). Then, the user terminal 12 transmits a lottery request (single lottery request or continuous lottery request) to the server 15 (S9).

Then, the server 15 executes lottery processing based on the lottery request (S10). When the server 15 acquires a single lottery request, the server 15 performs a single lottery process. Further, when the server 15 acquires a continuous lottery request, the server 15 performs continuous lottery processing. Details of the processing of S10 will be described later.

After the lottery process, the server 15 transmits to the user terminal 12 the remaining number of all objects in the shared box and information about the objects won as a result of the lottery (including object information about the privilege if a privilege is also won). (S11).

The user terminal 12 receives the remaining number of all objects in the shared box and the lottery result from the server 15 . Then, the user terminal 12 reflects the remaining number of all objects in the shared box in the remaining number display column 55 of the lottery screen 51 based on the remaining number of all objects in the shared box. Further, based on the received lottery result, the user terminal 12 displays the picture of the object that won the lottery on the lottery screen 51, and also displays the picture of the object for the identification if the privilege is won (S12). . Specifically, for example, the storage unit 23 of the user terminal 12 stores game element data 25 . It is assumed that the game element data 25 also includes graphic data, parameter data, and the like related to objects to be drawn. However, the lottery target object eta cannot be used or displayed by the user unless it is won in the lottery. When the user terminal 12 acquires the object ID of the winning object as a lottery result, the user terminal 12 can read the graphic data corresponding to the object ID from the game element data 25 and display it on the lottery screen 51 . After the process of S12, the process returns to S3.

It should be noted that the processing (S3 to S7) enclosed by the dashed line occurs while the lottery screen 51 is being displayed. That is, each user terminal 12 on which the lottery screen 51 is open periodically inquires of the server 15 about the remaining number of all objects in the shared box. Periodic may be, for example, an interval of n (n is a real number greater than 0) seconds.

FIG. 9 is a flow chart of the shared box remaining number acquisition process (S5) in this embodiment. The shared box remaining number acquisition process (S5) is executed when the screen 14 of the user terminal 12 transitions from another screen to display the lottery screen 51, and is periodically executed while the lottery screen 51 is displayed. executed as expected.

The server 15 (request acquisition unit 33) retrieves the total objects of the shared box from the user terminal 12 on which the lottery screen 51 is displayed after transitioning from another screen to the screen 14, or from the user terminal 12 on which the lottery screen 51 is displayed. acquires an inquiry request about the remaining number of (S21).

In response to the inquiry request, the server 15 (box management unit 35) acquires the remaining total number of shared box objects from the shared box management DB 43 (S22). In the case of FIG. 4B, the number of remaining objects with object ID=A0001 is 8, the number of remaining objects with object ID=A0002 is 10, and the number of remaining objects with object ID=A0003 is 1. As a result, the total remaining number of objects in the public box is 8+10+1=19.

The server 15 box management unit 35) transmits the remaining total number of objects in the shared box acquired from the shared box management DB 43 as the inquiry result to the user terminal 12 that made the inquiry (S23).

Upon receiving the inquiry result from the server 15, the user terminal 12 reflects the remaining number of all objects in the shared box in the remaining number display column 55 of the lottery screen 51 based on the inquiry result.

As a result, the user terminal 12 on which the lottery screen 51 is displayed by transitioning from another screen to the screen 14, or the user terminal 12 on which the lottery screen 51 is being displayed, is the latest all objects in the shared box at the time of the inquiry. The remaining number can be reflected in the remaining number display column 55 of the lottery screen 51. - 特許庁

FIG. 10 is a flowchart of lottery processing (S10) in Example 1 of the present embodiment. In the first embodiment, an example of using a shared box as a lottery box will be described. The control unit 32 functions as a request acquisition unit 33, a lottery unit 34, a box management unit 35, and a provision unit 36 by reading programs according to the present embodiment.

The request acquisition unit 33 acquires the lottery request (including the user ID) transmitted from the user terminal 12 (S31). The lottery unit 34 determines whether the lottery request is a single lottery request or a continuous lottery request (S32). If the lottery request is determined to be a single lottery request (NO in S32), the lottery unit 34 sets the parameter n (integer) to "1" (S33). When the lottery request is determined to be a continuous lottery request (YES in S32), the lottery unit 34 sets the parameter n (integer) to "X" (X: a predetermined integer) (S34).

The lottery section 34 determines one of the objects from the shared box management DB 43 based on the lottery request (S35). The box management unit 35 adds the winning number of the determined object from the shared box management DB 43, reduces the remaining number, and updates the winning probability (S36). The box management unit 35 acquires the remaining total number of objects in the shared box after the subtraction. At this time, the box management unit 35 adds the object ID of the determined object to the user-owned object management DB 42 based on the user ID.

The box management unit 35 determines from the shared box management DB 43 whether or not the remaining total number of objects in the shared box is equal to or less than a predetermined number (S37). Here, the predetermined number may be any integer, such as 0. If the remaining total number of objects in the shared box is greater than the predetermined number (NO in S37), the providing unit 36 stores the remaining total number of objects in the shared box acquired in S36 and the objects determined in S32. The object information is transmitted to the user terminal 12 (S38).

If the remaining total number of objects in the shared box is equal to or less than the predetermined number (YES in S37), the lottery section 34 acquires an object ID registered as a privilege from the privilege management DB 45 (S39). At this time, the box management unit 35 adds the object ID of the acquired privilege to the user-owned object management DB 42 based on the user ID.

The providing unit 36 transmits the remaining number of total objects in the shared box acquired in S36, the object information about the objects determined in S32, and the object information as a privilege to the user terminal 12 (S40).

The processing of S35-S40 is repeated n times. In S34, the lottery section 34 may check the remaining number of all objects in the shared box, and change the number of consecutive lotteries according to the remaining number.

FIG. 11 is a flowchart of lottery processing (S10) in Example 2 of the present embodiment. In a second embodiment, an example of using a shared box and individual user boxes as lottery boxes will be described.

The request acquisition unit 33 acquires the lottery request (including the user ID) transmitted from the user terminal 12 (S51). The lottery unit 34 determines whether the lottery request is a single lottery request or a continuous lottery request (S52). If the lottery request is determined to be a single lottery request (NO in S52), the lottery unit 34 sets the parameter n (integer) to "1" (S53). When the lottery request is determined to be a continuous lottery request (YES in S52), the lottery unit 34 sets "X" (X: a predetermined integer) to the parameter n (integer) (S54).

The lottery unit 34 determines one of the objects from the shared box (shared box management DB 43) and the user box (user box management DB 44) based on the first probability and the second probability (S55). Here, the first probability is the probability that the shared box is selected from the shared box and the user's box, and is indicated by probability k (0<k≦1). The second probability is the probability that the user's box is selected from the shared box and the user's box, and is indicated by probability 1−k.

The box management unit 35 determines whether or not the determined object has been determined from the shared box (S56). If it is determined that the determined object has been determined from the shared box (YES in S56), the box management unit 35 adds the number of winnings of the determined object from the shared box management DB 43, reduces the remaining number, and updates the winning probability. (S57). The box management unit 35 acquires the remaining total number of objects in the shared box after the subtraction. At this time, the box management unit 35 adds the object ID of the determined object to the user-owned object management DB 42 based on the user ID.

Also, at this time, the lottery unit 34 may adjust the first probability and the second probability (S58). For example, when an object is determined from a shared box, the lottery section 34 may adjust the first probability to be lowered and the second probability to be raised.

The box management unit 35 determines from the shared box management DB 43 whether or not the remaining total number of objects in the shared box is equal to or less than a predetermined number (S59). Here, the predetermined number may be any integer, such as 0. If the remaining total number of objects in the shared box is greater than the predetermined number (NO in S59), the provision unit 36 determines the remaining total number of objects in the shared box acquired in S57 and the objects determined in S55. The object information is transmitted to the user terminal 12 (S60).

If the remaining total number of objects in the shared box is equal to or less than the predetermined number (YES in S59), the lottery section 34 acquires an object ID registered as a privilege from the privilege management DB 45 (S61). At this time, the box management unit 35 adds the object ID of the acquired privilege to the user-owned object management DB 42 based on the user ID.

The providing unit 36 transmits the remaining total number of objects in the shared box acquired in S57, the object information about the objects determined in S32, and the object information as a privilege to the user terminal 12 (S62).

If it is determined that the determined object has been determined from the user-specific box (NO in S56), the box management unit 35 adds the winning number of the determined object from the user-specific box management DB 44 based on the user ID, Decrease the number and update the winning probability (S63). The box management unit 35 acquires the remaining total number of objects in the user-specific box after the subtraction. At this time, the box management unit 35 adds the object ID of the determined object to the user-owned object management DB 42 based on the user ID.

The box management unit 35 determines from the user-specific box management DB 44 whether or not the remaining total number of objects in the user-specific box is 0 (S64). If the remaining total number of objects in the user-specific box is not 0 (NO in S64), the providing unit 36 transmits object information about the object determined in S55 to the user terminal 12 (S67).

When the total remaining number of objects in the user-specific box is 0 (NO in S64), the box management unit 35 selects objects in the user-specific box managed by the user-specific box management DB 44 based on the user ID. The number is reset to the initial state (S65). The box management unit 35 increases the first probability k compared to before the reset (S66).

The providing unit 36 transmits object information about the object determined in S32 to the user terminal 12 (S67).

A loop process including S55 to S67 is repeated n times. However, when n (=X)≧2, the first probability of at least one loop process may be set to 1. In other words, the lottery section 34 may draw lots from the shared box at least once during the continuous lottery.

Further, in S54, the lottery section 34 may check the remaining number of all objects in the shared box, and vary the number of consecutive lotteries according to the remaining number.

According to this embodiment, in a lottery in which a limited number of remaining lottery targets are shared and managed by a plurality of users, it is possible to improve the user's expectation value for winning an object that has not yet been selected.

Further, when an object is determined from the shared box multiple times in the continuous lottery, the lottery section 34 may lower the second probability in subsequent lotteries in the continuous lottery. As a result, it is possible to suppress multiple winnings in the continuous lottery.

The lottery unit 34 may increase the second probability for a user who has obtained many objects taken out from the shared box. Thereby, equality between users can be ensured.

Also, the lottery unit 34 may determine an object with a higher rarity in the shared box as the remaining number of objects in the shared box decreases. That is, the lottery unit 34 may win objects in ascending order of rarity, and may win objects with a higher rarity as the remaining number decreases.

The privilege may be, for example, a character or item that appears in the game, an object such as in-game currency, a predetermined effect for advancing the game in an advantageous manner, predetermined music, or a coupon. It may be a ticket or the like. As for the privilege, the details of the privilege may be displayed on the lottery screen 51 before the lottery. For example, the content of the privilege that the user who wins the last object in the shared box may receive is displayed on the lottery screen 51 before the lottery.

Also, the contents of the objects managed in the user-specific box and the objects managed in the shared box may be different. The different items are, for example, different types or different degrees of rarity (for example, an object managed in a public box is higher in rarity than an object managed in a user-specific box). There may be.

The lottery section 34 may draw lots from the shared box at least once in the continuous lottery. In this case, the lottery screen 51 may display that the lottery will be conducted at least once from the shared box when the continuous lottery is selected. In this case, it can be expected that the user will have a stronger tendency to select consecutive lotteries.

The lottery unit 34 may randomly draw objects from the shared box (shared box management DB 43) or the user-specific box (user-specific box management DB 44). good too. The predetermined rule is, for example, to win objects in ascending order of rarity, or to win objects in descending order of rarity.
