In the following description, an input operation such as an action of a user's finger touching a position corresponding to the operation button displayed on the display is simply expressed as a user operating the operation button.

[Game server configuration]
FIG. 3 is a block diagram showing a configuration of the game server 102 included in the game system 100 according to the present embodiment. The game server 102 includes a game control unit 102a, a storage unit 102b, an access management unit 102c, a user information management unit 102d, and an output management unit 102e.

  The access management unit 102c receives a login request from a registered user and outputs login data to the user information management unit 102d.

  The user information management unit 102d authenticates whether or not the user who has attempted to log in to the game server 102 by operating the user terminal 110 is a registered user.

  The output management unit 102e transmits the data generated by the game control unit 102a to the user terminal 110.

[Configuration of game control unit]
A configuration of the game control unit 102a according to the present embodiment will be described. FIG. 4 is a block diagram illustrating a configuration of the game control unit 102a realized by executing a game program stored in the storage unit 102b of the game server 102.

  The game control unit 102a includes a participation group generation unit 102f, a participant search unit 102g, a lottery table change unit 102h, a lottery processing unit 102i, a content assignment unit 102j, and a screen data creation unit 102k.

  The participation group generation unit 102f generates a group composed of participants. The group is generated when a user who has applied for participation in the lottery process is registered as a participant in the lottery process and there are a plurality of participants.

  The participant search unit 102g searches for a candidate for a lottery process. Specifically, the first participant of the lottery process searches for a user who has a friendship in the SNS. And the user who has the said friend relationship is invited to the said lottery process. When the participant search unit 102g receives information on the user specified by the first participant from the user terminal 110 owned by the first participant, the first participant receives the first participant from the user who has a friendship in the SNS. Search for the user specified by. And the participant search part 102g transmits the invitation message 120 of a lottery process to the searched user via the SNS server 106, for example. The user who has received the invitation message 120 can apply for participation in the lottery process. In the present embodiment, the first participant is a user who intends to host the lottery process, and hereinafter, the first participant is referred to as the host.

  Note that if the participant search unit 102g has not received replies from all the participation candidates after a predetermined time has elapsed since the participant search unit 102g transmitted the invitation message 120, the participation group generation unit 102f ends the registration process. Also good. In that case, the lottery process may be executed only by the participants registered at this time.

  The lottery table changing unit 102h prepares a lottery table. In the lottery table, acquisition probabilities for each of a plurality of types of content are set. The acquisition probability of each of the plurality of types of contents is set according to the number of a plurality of participants that constitute the group. Here, the content includes items, points, currency, and the like effective in the game. The lottery table changing unit 102h includes a lottery table reading unit 102l and a lottery table creating unit 102m.

  When a plurality of participants configuring the group are determined, the lottery table reading unit 102l prepares a lottery table used for the lottery process by reading the lottery table stored in the game database.

  When a plurality of participants making up the group are determined, the lottery table creating unit 102m prepares a lottery table by newly creating a lottery table. The newly created lottery table may be newly stored in the game database.

  In the lottery process, a lottery table may be prepared by either the lottery table reading unit 102l or the lottery table creating unit 102m.

  The lottery table is set according to the number of participants making up the group. The lottery table includes the setting of the first content and the second content having a higher acquisition probability than the first content, and the increase in the number of a plurality of participants constituting the group increases the probability of the first content acquisition. The increase rate may be set to be higher than the increase rate of the second content acquisition probability.

  For example, the lottery table may be set such that the rate of increase in the acquisition probability with respect to the increase in the number of a plurality of participants constituting the group increases as the content has a lower acquisition probability.

  FIG. 5 is a diagram for explaining the lottery table. This example shows a lottery table when the number of participants is 3 (upper row) and 4 (lower row), and includes 10 types of available content n (n = 1 to 10). Each acquisition probability (shown as “appearance probability” in the figure) is associated with each other. In the lottery table, the total occurrence probability is set to be 100 [%]. That is, the participant can obtain any content.

  FIG. 6 is a graph showing the content ID on the horizontal axis and the appearance probability on the vertical axis for the lottery table shown in FIG. As can be seen from the graph, in this example, in any content, the increase rate of the appearance probability when the number of participants is 4 is higher for the content with a lower appearance probability than the appearance probability when the number of participants is 3 large.

In this example, the appearance probability P _3n [%] of content n when there are three participants and the appearance probability P _4n [%] of content n when there are four participants are respectively
P _3n = 100 × exp (−n / 3) / Σ _k exp (−k / 3),
P _4n = 100 × exp (−n / 4) / Σ _k exp (−k / 4)
It is said. Furthermore, generalizing, the appearance probability P _mn [%] of the content n when the number of participants is m (m is an integer),
P _mn = 100 × exp (−n / m) / Σ _k exp (−k / m)
It is good. The function form for creating the lottery table and the parameters included therein are not limited to this example.

  By using the lottery table as described above, as the number of participants in the lottery process increases, it becomes easier to obtain content with a low acquisition probability (rare). As a result, the organizer of the lottery process has a motivation to invite as many participants as possible, and the user who has become a candidate for participation has a motivation to participate in the lottery process.

  The lottery table changing unit 102h may be able to change the setting of the lottery table according to the date and time when the lottery process is executed. As the setting of the lottery table, for example, a plurality of types of content may be used, or the acquisition probability of each of the plurality of types of content may be used.

  As an example, in a specific period (event period), as the number of the plurality of participants increases, newly available content may be added or deleted. Here, the newly added content may be content with a relatively low acquisition probability. Further, the content to be deleted may be a content with a relatively high acquisition probability.

  As another example, in a specific period (event period), the rate of increase in the acquisition probability with respect to the increase in the number of a plurality of participants constituting the group is set higher than in the regular lottery table. Also good.

  About such an event period, the game server 102 may notify the registered user of the game in advance. As a notification method, for example, it may be displayed on the start screen of the game application.

  The lottery table changing unit 102h may be able to change a plurality of types of content according to the information of the group. The group information may be, for example, the number of a plurality of participants constituting the group, or the presence or absence of a specific participant in the group.

  For example, in a specific period (event period), as the number of the plurality of participants increases, or when a specific participant is included, newly available content may be added or deleted. Here, the newly added content may be content with a relatively low acquisition probability. Further, the content to be deleted may be a content with a relatively high acquisition probability.

  Here, the specific participant is, for example, a participant having a certain level or higher, a participant having a specific difficult-to-obtain content, or a maximum score exceeding a certain level in the history of playing the game. It may be an experienced user who has If such a user sponsors or participates in the lottery process, the user who becomes another candidate for participation has a motivation to participate in the lottery process.

  The lottery processing unit 102i executes a lottery process for each of the plurality of participants. In the lottery process, the lottery table prepared by the lottery table changing unit 102h is used. The lottery processing unit 102i includes an individual lottery processing unit 102n.

  The individual lottery processing unit 102n executes an individual lottery process corresponding to a combination of an arbitrary participant X and an arbitrary participant Y other than the participant X in one lottery process.

  In order to explain the individual lottery process, an example of the lottery process will be briefly described. FIG. 7 is a diagram illustrating an example of the individual lottery process. In this example, three people, participant A, participant B, and participant C, participate in the lottery process.

  Participant A has a combination Pab with participant B and a combination Cac with participant C. Participant A obtains the content Cab by the individual lottery process Gab for the combination Pab, and obtains the content Cac by the individual lottery process Gac for the combination Pac. That is, the participant A has the opportunity of the individual lottery process twice.

  Similarly, the participant B has a combination Pba with the participant A and a combination Pbc with the participant C. Participant B obtains the content Cba through the individual lottery process Pba for the combination Pba, and obtains the content Cbc through the individual lottery process Gbc for the combination Pbc. That is, the participant B has the opportunity of the individual lottery process twice.

  Similarly, the participant C has a combination Pca with the participant A and a combination Pcb with the participant B. The participant C obtains the content Cca by the individual lottery process Gca for the combination Pca, and obtains the content Ccb by the individual lottery process Gbc for the combination Pcb. That is, the participant C has the opportunity of the individual lottery process twice.

  That is, when the number of participants is N (N is an integer equal to or greater than 2), each of the plurality of participants has an opportunity of N-1 individual lottery processes. Therefore, N (N-1) individual lottery processes are executed in one lottery process.

  The individual lottery processing unit 102n may impose a limit on the number of individual lottery processes. That is, when the individual lottery processing unit 102n executes the individual lottery process corresponding to an arbitrary combination a predetermined number of times, the individual lottery process corresponding to the combination may be invalidated until a predetermined release condition is satisfied. For example, when the individual lottery process Gxy and the individual lottery process Gyx for each combination of an arbitrary participant X and an arbitrary participant Y other than the participant X are executed once, until the release condition is satisfied thereafter, The individual lottery process Gxy and the individual lottery process Gyx may be invalidated. The release condition may be that a certain period (for example, 24 hours) elapses from the time when the individual lottery process Gxy and the individual lottery process Gyx are executed.

  The number limit and release conditions are not limited to the above example. The number of times is not limited to once until the cancellation condition is satisfied, and two or more individual lotteries may be possible. The release condition may be, for example, that a certain period of time has elapsed after reaching the frequency limit, or may be the next day after reaching the frequency limit.

  The individual lottery processing unit 102n executes the individual lottery process independently for each of the plurality of participants. That is, it will be as follows when paying attention to a combination of an arbitrary participant X and an arbitrary participant Y other than the participant X. Participant X has a combination Pxy with participant Y. The participant X obtains the content Cxy through the individual lottery process Gxy for the combination Pxy. Participant Y has a combination Pyx with participant X. The participant Y obtains the content Cyx through the individual lottery process Gyx for the combination Pyx. Here, the individual lottery process Gxy and the individual lottery process Gyx are executed independently. That is, in the individual lottery process, when a random number is generated using an arbitrary numerical value (for example, an integer) as a seed and the random number is used, different seeds of random numbers may be used in the individual lottery process Gxy and the individual lottery process Gyx. Thus, the content Cxy and the content Cyx are not necessarily the same content.

  The content assigning unit 102j assigns one of a plurality of types of content to the participant according to the result of the lottery process.

  The content granting unit 102j may update the content with a lower acquisition probability among the content acquired by one participant and the content obtained by the other participant with a content with a higher acquisition probability. That is, it will be as follows when paying attention to the combination of an arbitrary participant X and an arbitrary participant Y other than the participant X. Participant X has a combination Pxy with participant Y. The participant X obtains the content Cxy through the individual lottery process Gxy for the combination Pxy. Participant Y has a combination Pyx with participant X. The participant Y obtains the content Cyx through the individual lottery process Gyx for the combination Pyx.

  Here, for example, in a specific period (event period), out of the content Cxy and the content Cyx, the content with the lower acquisition probability may be updated to the content with the higher acquisition probability. That is, both the participant X and the participant Y obtain the content with the lower acquisition probability among the content Cxy and the content Cyx.

  The screen data creation unit 102k generates screen data to be displayed on the screen of the user terminal according to the processing content of the game control unit 102a.

  When the result of the lottery process is confirmed, the screen data creation unit 102k displays the ID of the target participant and the content obtained by the combination of the target participant and the content associated with each of the display terminals of the plurality of participants. You may create a screen to do. That is, in a combination of an arbitrary participant X and an arbitrary participant Y other than the participant X, the participant X's user terminal is combined with the ID of the participant Y and the combination of the participant X and the participant Y. A screen for associating and displaying the content Cxy obtained by the participant X by the corresponding individual lottery process Gxy is created.

  The configuration of the game device according to this embodiment has been described above. According to the configuration of the game device according to the present embodiment, a game including a lottery process in which any of a plurality of types of content can be obtained in the progress of the game and the content acquisition probability is changed according to the number of participants is provided. can do.

[Processes executed by the game system]
Processing executed by the game system 100 according to the present embodiment will be described. FIG. 8 is a diagram illustrating processing executed by the game system 100 according to the present embodiment using the above functions. In addition, although there is no restriction | limiting in the number of users who participate in the lottery process demonstrated below, in the drawing, the user A (organizer) who owns the user terminal 110A and the user B who owns the user terminal 110B are representative. It shows. Since the process related to the user terminal 110 owned by other participants is the same as the process related to the user terminal 110B, it is omitted.

  First, the user terminal 110A activates a game application according to an instruction from the user A (S100). When the application is activated, an activation screen is displayed on the display of the user terminal 110A, and the user A plays a game.

  The user terminal 110A may move to a mode for executing a lottery process. In that case, an invitation screen 114 for designating a user or group to be invited to the lottery process is displayed on the user terminal 110A.

  FIG. 9 is a diagram illustrating an example of the invitation screen 114 displayed on the user terminal 110A owned by the user A. The invitation screen 114 displays information for identifying the user, such as the user name and avatar of the user who can be invited.

  On the invitation screen 114, by designating a user who wants to invite to the lottery process on the invitation screen 114 and operating the invitation button 116, the user designated as a candidate for participation is instructed to the game server (S101). Is transmitted from the user terminal 110A to the game server 102 (S102). Here, the number of users that can be specified is arbitrary.

  When the game server 102 receives from the user terminal 110A information about a user who is a candidate for participation designated by the user A, the participant search unit 102g determines whether the user A (organizer) has a friendship in the SNS from the user. The user designated by A is searched (S400). The participant search unit 102g transmits the searched user information to the SNS server 106 in order to send an invitation message to the searched user via the SNS server (S401).

  When the SNS server 106 receives the searched user information, the SNS server 106 creates an invitation message 120 for notifying the user including the user B indicated by the searched user information (S300), and the searched user's user terminal The invitation message 120 is transmitted to 110 (S301).

  For example, when the user terminal 110B receives the invitation message 120 from the SNS server 106, the dialogue screen 118 provided by the SNS server 106 is displayed on the display of the user terminal 110B, and the invitation message 120 is displayed on the dialogue screen 118 (S200). .

  FIG. 10 is a diagram illustrating an example of an invitation message 120 that is notified to a searched user. In the invitation message 120, the nickname and avatar of the user A who is the organizer are displayed, and an invitation message 120 for the lottery process is displayed.

  When the user operates the portion of the invitation message 120, the game application is activated (S201). That is, the invitation message 120 also functions as an indicator for starting a game application. The indicator for starting the game application may be an icon, a link, or the like different from the invitation message 120.

  Then, when the user who has received the invitation message 120 intends to participate in the lottery process, the user applies to the game server 102 (S202). As a method for applying for participation, for example, a confirmation button displayed on the game screen may be operated.

  When each of the participation candidates notifies that they will participate in the lottery process, in the game server 102, the participation group generation unit 102f registers the user who applied for participation in the lottery process as a participant in the lottery process. A group composed of a plurality of participants is generated (S402).

  After the participation registration process has been completed for all the users who have received the invitation message, or after a predetermined time has elapsed since the participant search unit 102g transmitted the invitation message 120, the game server 102 receives each user of the participant. The terminal 110 is instructed to display the lottery process start screen (S403), and the process proceeds to the lottery process (S404).

  A lottery process start screen is displayed on the display of each user terminal 110 of the participant. When each participant operates the start button displayed on the start screen, the lottery processing unit 102i in the game server 102 executes a lottery process on the participants constituting the group.

  The details of the process executed in the lottery process will be described with some examples in [Example of lottery process] to be described later.

  When the lottery process ends, the game server 102 transmits the result of the lottery process to the user terminal 110 (S405). At this time, the content assigning unit 102j assigns one of a plurality of types of content to the participant according to the result of the lottery process.

  When the content given to each of the plurality of participants is determined, the screen data creation unit 102k displays the ID of the target participant and the combination of itself and the target participant on each display terminal of the plurality of participants. A screen for associating and displaying the content acquired by the above is created and displayed on the display of the user terminal 110. FIG. 11 is a diagram illustrating an example of a lottery process result screen displayed on the user terminal 110 owned by each of three participants A, B, and C participating in the lottery process. .

  That is, in a combination of an arbitrary participant X and an arbitrary participant Y other than the participant X, the participant X's user terminal is combined with the ID of the participant Y and the combination of the participant X and the participant Y. A screen for associating and displaying the content Cxy obtained by the participant X by the corresponding individual lottery process Gxy is generated and instructed to be displayed on the display of the user terminal 110.

  Here, the content providing unit 102j updates the content with the lower acquisition probability to the content with the higher acquisition probability among the content acquired by one participant and the content acquired by the other participant. Good.

  The user terminal 110 displays the screen created by the screen data creation unit 102k as a result of the lottery process transmitted from the game server 102 (S103).

  The process executed in the game device according to the present embodiment has been described above. Next, in the process executed in the game device according to the present embodiment, the process related to the lottery process will be described in detail.

[Example of lottery processing]
The lottery process will be described with some examples. In the following example, it is assumed that the number of individual lottery processing limits and the cancellation conditions thereof are set as follows. When one individual lottery process with an arbitrary combination of a plurality of participants ends, the individual lottery process with the combination is invalid within 24 hours from the end of the individual lottery process, and from the end of the individual lottery process The elapse of 24 hours is set as a condition for releasing the restriction on the number of times.

  In the example described below, the lottery process 1, the lottery process 2, the lottery process 3, the lottery process 4, and the lottery process 5 are executed in this order. Here, the lottery process 2 is executed within 24 hours of the lottery process 1. The lottery process 3 and the lottery process 4 are executed after 24 hours of the lottery process 2. The lottery process 5 is executed within 24 hours of the lottery process 3 and the lottery process 4.

  First, the lottery process 1 will be described. FIG. 12 is a diagram for explaining the lottery process 1. In this example, a participant A (organizer), a participant B, and a participant C are participating in the lottery process 1.

  After the participation registration process for these participants is completed, the lottery table changing unit 102h prepares a lottery table. In the lottery table, a plurality of types of content acquisition probabilities are set.

  For the participant A, the combination Pab with the participant B and the combination with the participant C have Pac. Participant A obtains the content Cab by the individual lottery process Gab for the combination Pab, and obtains the content Cac by the individual lottery process Gac for the combination Pac.

  Similarly, the participant B has a combination Pba with the participant A and a combination Pcb with the participant C. Participant B obtains the content Cba through the individual lottery process Gba for the combination Pba, and obtains the content Cbc through the individual lottery process Gbc for the combination Pbc.

  Similarly, for the participant C, the combination Pca with the participant A and the combination Pcb with the participant B are included. Participant C obtains content Cca by individual lottery process Gca for combination Pca, and obtains content Ccb by individual lottery process Gcb for combination Pcb.

  Here, as described above, the individual lottery processing unit 102n executes the individual lottery process independently for each of the plurality of participants. That is, for example, the content Cab obtained by the participant A through the individual lottery process in combination with the participant B and the content Cba obtained by the participant B through the individual lottery process in combination with the participant A are not necessarily the same content. is not. For example, when the content Cab is a content having a lower acquisition probability (rare) than the content Cba, the participant B is not satisfied with the result, and includes a combination with the participant A at a later opportunity. Motivation to try again the lottery process works.

  Next, an example of the lottery process 2 executed after the lottery process 1 will be described. FIG. 13 is a diagram for explaining the lottery process 2. In this example, four people, Participant A, Participant B, Participant C, and Participant D participate in the lottery process. In this example, after the lottery process 1 is completed, in addition to the participant A, the participant B, and the participant C, the participant D newly participates to perform the lottery process 2.

  As described above, since the lottery process 2 is executed within 24 hours from the end of the lottery process 1, a number limit is imposed on any combination of the participant A, the participant B, and the participant C. The release condition is not satisfied.

  The participant A has a combination Pab with the participant B, a combination Pac with the participant C, and a combination Pad with the participant D. For the participant A, the individual lottery process Gab for the combination Pab and the individual lottery process Gac for the combination Pac are invalid due to the above-mentioned number of times limitation. For the participant A, the individual lottery process Gad for the combination pad is effective. Accordingly, the participant A obtains the content Cad through the individual lottery process Gad.

  The participant B has a combination Pba with the participant A, a combination Pbc with the participant C, and a combination Pbd with the participant D. For the participant B, the individual lottery process Gba for the combination Pba and the individual lottery process Gbc for the combination Cbc are invalid due to the above-mentioned number of times limit. For the participant B, the individual lottery process Gbd for the combination Pbd is effective. Accordingly, the participant B obtains the content Cbd through the individual lottery process Gbd.

  The participant C has a combination Pca with the participant A, a combination Pcb with the participant B, and a combination Pcd with the participant D. For the participant C, the individual lottery process Gca for the combination Pca and the individual lottery process Gcb for the combination Pcb are invalid due to the above-mentioned number of times limitation. For the participant C, the individual lottery process Gcd for the combination Pcd is effective. Accordingly, the participant C obtains the content Ccd through the individual lottery process Gcd.

  The participant D has a combination Pda with the participant A, a combination Pdb with the participant B, and a combination Pdc with the participant C. For the participant D, the individual lottery process Gda for the combination Pda, the individual lottery process Gdb for the combination Pdb, and the individual lottery process Gdc for the combination Pdc are effective. Accordingly, the participant D obtains the content Cda through the individual lottery process Gda, obtains the content Cdb through the individual lottery process Gdb, and obtains the content Cdc through the individual lottery process Gdc.

  Here, the number of participants in the lottery process 2 is four, whereas the number of participants in the lottery process 1 is three. That is, there are more participants in the lottery process 2 than in the lottery process 1. Therefore, the lottery table used in the lottery process 2 has a lower probability of acquisition (rare) than the lottery table used in the lottery process 1, and the probability of acquisition for the increase in the number of participants from three to four. The rate of increase is set high.

  Next, an example of the lottery process 3 executed after the lottery process 2 will be described. FIG. 14 is a diagram illustrating the lottery process 3. In this example, two participants A and B participate in the lottery process 3.

  Note that, as described above, the lottery process 3 is executed 24 hours after the end of the lottery process 1, and therefore the condition for releasing the restriction on the number of combinations of the participant A and the participant B is satisfied.

  Participant A has a combination Pab with participant B. Participant A obtains the content Cab by the individual lottery process Gab for the combination Pab.

  Participant B has a combination Pba with participant A. Participant B obtains the content Cba through the individual lottery process Gba for the combination Pba.

  Next, an example of the lottery process 4 executed after the lottery process 3 will be described. FIG. 15 is a diagram for explaining the lottery process 4. In this example, two participants A and C participate in the lottery process 4.

  Note that, as described above, the lottery process 4 is executed 24 hours after the end of the lottery process 2, and therefore the condition for releasing the restriction on the number of combinations of the participant A and the participant C is satisfied.

  Participant A has a combination Pac with participant C. Participant A obtains the content Cac through the individual lottery process Gac for the combination Pac.

  Participant C has a combination Pca with participant A. The participant C obtains the content Cca through the individual lottery process Gca for the combination Pca.

  Next, an example of the lottery process 5 executed after the lottery process 4 will be described. FIG. 16 is a diagram for explaining the lottery process 5. In this example, three of the participant A, the participant B, and the participant C participate in the lottery process 5.

  As described above, since the lottery process 5 is executed within 24 hours from the end of the lottery process 3 and the lottery process 4, the combination of the participant A and the participant B and the combination of the participant A and the participant C are performed. The above-mentioned number of times restriction is imposed on and the release condition is not satisfied.

  Participant A has a combination Pab with participant B and a combination Pac with participant C. For the participant A, the individual lottery process Gab for the combination Pab and the individual lottery process Gac for the combination Pac are invalid due to the above-mentioned number of times limitation. Therefore, the participant A cannot obtain the content by the lottery process 5.

  Participant B has a combination Pba with participant A and a combination Pbc with participant C. For the participant B, the individual lottery process Gab for the combination Pab is invalid due to the above-mentioned number of times limitation. For the participant B, the individual lottery process Gbc for the combination Pbc is effective. Therefore, the participant B obtains the content Cbc through the individual lottery process Gbc.

  The participant C has a combination Pca with the participant A and a combination Pcb with the participant B. For the participant C, the individual lottery process Gca for the combination Pca is invalid due to the above-mentioned number-of-times limitation. For the participant C, the individual lottery process Gcb for the combination Pcb is effective. Accordingly, the participant C obtains the content Ccb through the individual lottery process Gcb.

  In the lottery process 5, the individual lottery process based on the combination of the participant A and other participants is invalid, so the participant A cannot obtain the content. However, since there are three participants in the lottery process 5, the lottery process is performed using the lottery table in the case of three persons. That is, as for the participant B and the participant C, by obtaining the participant A, the probability of acquisition is low compared with the case where the participant B and the participant C perform the lottery process (rare) ) The probability of getting content increases. As a result, the organizer of the lottery process has a motivation to invite as many participants as possible, and the user who has become a candidate for participation has a motivation to participate in the lottery process.

  The game system and the game progress according to the present embodiment have been described above. According to the game system according to the present embodiment, any of a plurality of types of content can be obtained, and a game including a lottery process for changing the content acquisition probability according to the number of participants can be provided.

Second Embodiment
A game system 100 according to the present embodiment will be described. The game system 100 according to the present embodiment differs from the first embodiment in the process of generating a group of participants.

  The participation group generation unit 102f registers only the user who applied for participation within a predetermined distance from the first participant when registering the user who applied for participation in the lottery process as a plurality of participants in the lottery process. May be. For example, registration can be limited to registered users that exist in the same building as the first participant, registered users that exist in the same room as the organizer, registered users that actually face the organizer, and the like.

  The participation group generation unit 102f receives, from the user terminal 110A possessed by the first participant, information on the distance designated by the first participant along with the application for participation in the lottery process. At this time, the location information of the user terminal owned by the first participant is also acquired. Thereafter, the first participant is prompted to participate by another registered user, and the participation group generation unit 102f receives the application for participation in the lottery process from the other registered user and acquires the location information of the registered user. . Here, the location information of the first participant and the registered user can be acquired by the GPS positioning unit 110d of the user terminal owned by each. If the distance between the first participant and the registered user is within the distance designated by the first participant, the participation group generation unit 102f registers the registered user as a participant.

[Processes executed by the game system]
Processing executed by the game system 100 according to the present embodiment will be described. FIG. 17 is a diagram illustrating a process of generating a group of a plurality of participants participating in the lottery process in the process executed by the game system 100 according to the present embodiment using the above function. The description of the processes after the lottery process is the same as in the first embodiment, and will be omitted. The number of users participating in the lottery process described below is not limited, but in the drawing, user A (organizer) who owns user terminal 110A, user B who owns user terminal 110B, and user terminal 110C. 3 representatives of user C are shown.

  Here, it is assumed that the user B exists within a predetermined distance described later from the user A, and the user C exists away from the user A by a predetermined distance. Since the process related to the user terminal 110 owned by other participants is the same as the process related to the user terminal 110B or the user terminal C, it is omitted.

  First, the user terminal 110A activates a game application according to an instruction from the user A (S500). When the application is activated, an activation screen is displayed on the display of the user terminal 110A, and the user A plays a game. At this time, other registered users may activate the application of the game on the user terminals owned by the respective registered users (S501, S502) as long as they are activated at least in the application for participation in the lottery process. Good.

  The user terminal 110A may move to a mode for executing a lottery process. In this embodiment, the user A can invite a registered user who exists within a predetermined distance from the user A to the lottery process. The predetermined distance is, for example, a distance that can face each other, and may be 10 m, for example. User A applies to the game server 102 for his / her participation, and transmits his / her position information and the predetermined distance to the game server (S503).

  Thereby, the participation group generation unit 102f registers the user A as a participant (S600), and acquires the position information of the user A (S601).

  At this time, since the user A exists in a positional relationship that can face the user B, the user B can be invited to the lottery process, for example, verbally. In response to an invitation from user A, user B can apply for participation in the lottery process. As a participation application method, for example, the user B can apply for participation by an operation such as simultaneously vibrating the user terminal owned by the user A and the user terminal B owned by the user B (S504). When the participation group generation unit 102f detects the vibration of the user terminal B, the participation group generation unit 102f acquires the position information of the user terminal B (S602). Thereby, the distance between the user terminal A and the user terminal B is measured (S603). If this distance is within the predetermined distance, the participation group generation unit 102f registers the user B as a participant of the lottery process (S604).

  On the other hand, since user A exists in a positional relationship that cannot face user C, user A is not invited to the lottery process. Here, the user terminal C owned by the user C for some reason vibrates for some reason during the period in which the participation group generation unit 102f accepts the participation application, and the user C accidentally enters the lottery process. There is a case where an application for participation is made (S505). Even in such a case, the participation group generation unit 102f acquires the position information of the user terminal C as described above (S605), and measures the distance between the user terminal A and the user terminal C (606). Therefore, the user C who does not exist within the predetermined distance is not considered to have applied for participation in the lottery process in the group to which the user A belongs, and is considered to be an application for participation in another group.

  The participation application method is not limited to vibrating the user terminal 110. For example, it is good also as a participation application by displaying the button for participation application on the user terminal 110, and operating it.

  Further, the determination of the distance from the user A is not limited to the above example using the GPS positioning unit. As another example, before the application for participation, communication is performed between the user terminals 110 existing within a predetermined distance from the user A by Bluetooth (registered trademark) or the like to generate a common identifier or the like, and the identifier or the like is used as position information. It is good also as a participation application by transmitting to a game server instead of.

  After the participation registration process is completed for all users, or after a predetermined time has elapsed since user A's participation registration, the game server 102 proceeds to a lottery process (S407). Since the subsequent processing is the same as that of the first embodiment, description thereof is omitted.

  By including such processing, it is possible to enjoy the lottery processing between registered users who are actually facing each other. Furthermore, since participants of the lottery process can be convened while actually facing each other, it becomes easy to spread a game including such a lottery process not only to friends in SNS but also to friends in the real world. Furthermore, as a registered user, for example, even if you are considering uninstalling because you are tired of the game, the motivation to quit may decline if you are asked to participate face-to-face Be expected.

  The game system according to the present embodiment has been described above. According to the game device and the program according to the present embodiment, the registered users of the game can call the lottery process participants while actually meeting each other, so that it is easy to spread to friends in the real world.

<Third Embodiment>
A game system 100 according to this modification will be described. The game system 100 according to the present embodiment differs from the first embodiment and the second embodiment in the process of generating a group of participants.

  The participation group generation unit 102f may be a participant who forms the same group as the first participant when receiving a participation application from a user who has been sent an arbitrary code from the first participant. In other words, the first participant may transmit an invitation message 120 including an arbitrary code to a candidate for participation who wants to invite to the lottery process, for example, via a game application communication tool or an e-mail.

  The user who received the invitation message 120 can apply for participation in the lottery process by activating the game application and inputting the code.

  The preferred embodiments of the present invention have been described above. However, these are merely examples, and the technical scope of the present invention is not limited thereto. Those skilled in the art will be able to make various modifications without departing from the spirit of the present invention. Therefore, it should be understood that these changes also belong to the technical scope of the present invention.
