Each user can set, for example, unnecessary items among the items he / she owns as prizes to be drawn in the prize lottery game through the prize providing service.

  With reference to FIG. 3, a relationship between a prize set by each user as a lottery target (hereinafter sometimes referred to as a user-provided prize) and a prize lottery game will be described. FIG. 3 is an explanatory diagram for explaining a prize lottery game using a user-provided prize. FIG. 3 shows a case where, for example, the user “A” provides each item he / she owns as a prize for a prize lottery game through a prize providing service. As shown in FIG. 3, each item provided by the user “A” through the premium providing service is added as a user-provided premium (privilege candidate) to a lottery subject of the prize lottery game. In the prize lottery game using the user-provided prize set by the user “A” as a prize, participation in a lottery opportunity for obtaining each item of the user-provided prize is permitted in exchange for consumption of a predetermined value. Other users (other than the user “A”) in the number corresponding to the number of items set as the user-provided prize by the user “A” can participate in this lottery opportunity. In the example of FIG. 3, the user “A” sets three items as user-provided prizes, and in the prize lottery game using these as prizes, the user “B”, the user “C”, and the user “D” 3 There are other users participating. In the prize lottery game, these three other users are given a lottery opportunity to determine items to be given to each user by lottery in exchange for consumption of a predetermined price. Based on the lottery result, each item of the user-provided prize is given to each of the three other players.

  In addition, the user who has set the user-provided premium is provided with a reward according to the consideration consumed by the user to whom the lottery opportunity has been given, along with the grant of the lottery opportunity. For example, as such a reward, the total consideration consumed by the user who is given a lottery opportunity may be provided as it is. Alternatively, the reward may be a part of the total consideration, or another privilege having a value corresponding to the total consideration. On the other hand, in the prize lottery game, when the number of users corresponding to the number of items of the user-provided prizes does not gather, that is, when the number of users required for the lottery opportunity to obtain the user-provided prize does not participate, the user provision after a predetermined period It is determined that a prize lottery game for obtaining a prize is not established. If the failure is determined, the user-provided prizes are returned to the user who provided them, and the user continues to possess them. As described above, the prize lottery service includes a prize provision service for providing items possessed by each user as a lottery object and distributing them to other users through the lottery.

  The prize lottery service is provided through a prize setting screen, for example. More specifically, as an example, each user selects an item to be provided as a lottery object among items he / she owns through a prize setting screen. The premium setting screen may include a function for setting a predetermined period in which a user-provided lottery opportunity can be participated. Alternatively, the predetermined period may be set uniformly in advance.

  In addition, the user ID of the user who provided the prize may be provided to the user who has obtained the prize by lottery. And based on this user ID information, a connection may be formed between the user who has set the user-provided prize and the user who has obtained the prize by lottery. In the example of FIG. 3, a connection may be formed between the user “A” who provided the prize and the three users “B”, “C”, and “D” who obtained the prize by lottery. For example, such a connection may be given preferential treatment such as permitting limited information exchange in the community service. As an example, as a connection to which such preferential treatment is given, friend registration in a community service is well known.

  Next, details of the ID management data 22, the lottery data 23, and the play data 24 will be described. The ID management data 22 is data in which correspondence relationships between various IDs used in the game system 1 are described. For example, as described above, the correspondence relationship between the card ID (s) and the user ID is recorded in the ID management data 22. For example, the correspondence relationship between the chassis ID for specifying each game machine GM and the store ID for specifying each store 4 may be recorded.

  The play data 24 is a set of data created for each user ID. When a player plays an arcade game on any game machine GM, the card ID that the player has recognized by the game machine GM is provided to the center server 3. Then, at least a part of the play data 24 corresponding to the user ID associated with the card ID is provided from the center server 3 to the game machine GM and stored in the storage device 31 of the game machine GM. The same applies when a web service is provided. That is, at least a part is provided from the center server 3 to the user terminal 8 or the like so as to include a part corresponding to the user ID based on the user ID or the like used for the Web service.

  FIG. 4 is a diagram illustrating an example of the contents of the play data 24. As shown in FIG. 4, the play data 24 includes, for example, lottery logs and game data information in addition to the user ID. Each piece of information in the play data 24 is described in association with a user ID. The lottery log is information on a log that records the use results of the prize lottery service. The lottery log includes, for example, information related to usage results such as the number of lotteries and prizes obtained by the lottery. The game data is data provided for each game and used in each game. In the game data, information related to each game such as results recorded by the user in various arcade games or mobile games, points (or currency used in the game), and items owned by the user in the game are recorded. . Also, as an example, each item set as a user-provided prize may be deleted from the game data. In this case, when the prize lottery game is returned due to failure, the corresponding item is described in the game data again.

  The lottery data 23 is data for defining each lottery subject to be drawn in the prize lottery game. FIG. 5 is a diagram illustrating an example of the contents of the lottery data 23. As shown in FIG. 5, the lottery data 23 includes lottery ID, user ID, status, period, and premium information. The lottery data 23 is a set of records in which these pieces of information are described in association with each other. The lottery ID is an ID uniquely assigned to each record in order to manage each record. The user ID is an ID for identifying each user described above. In the record created through the free gift providing service, the user ID of the user who provided the free gift is described as the user ID information. On the other hand, in the case of a record created by an operator or the like, that is, a record that defines a lottery gift provided by the operator or the like, a unique ID may be described for each creator or the like. The period is information indicating a predetermined period in which participation in the lottery opportunity is possible. The status is information for managing the status of each record. As the status information, for example, information indicating a status such as a prize lottery game executed, not executed, or not established is used. The prize is information indicating an item or the like to be selected by lottery. In the lottery data 23, a lottery prize is associated with each prize provider in this way, and a lottery prize group is managed using a lottery ID for each lottery.

  Next, a lottery creation process and a prize lottery process will be described. The lottery creation process is executed in order to set items possessed by each user as user-provided prizes. The prize lottery process is executed in order to return the user-provided prize to the user after the lottery for which the user-provided prize is a lottery object and a predetermined period. As an example, the lottery creation process and the prize lottery process are executed by the control unit 10 of the center server 3 through the Web service management unit 17. In addition, the lottery creation process and the prize lottery process may be executed by the control unit 30 of the game machine GM or the control unit 40 of the user terminal 8. These control units 10, 30, and 40 execute various well-known processes necessary for providing a predetermined game, game machine service, and Web service, respectively, or in cooperation with each other. Detailed description is omitted.

  FIG. 6 is a diagram illustrating an example of a flowchart of a lottery creation process routine. As an example, the routine of FIG. 6 is executed every time a predetermined creation condition is satisfied. The predetermined creation condition is satisfied when, for example, necessary information is input on the prize setting screen, or when a predetermined operation indicating completion of input (for example, an operation of pressing an end button or the like) is executed. It is. That is, as an example, the routine of FIG. 6 is executed every time input of necessary information is completed on the prize setting screen.

  When the routine of FIG. 6 is started, first, in step S11, the Web service management unit 17 acquires lottery information necessary for executing a lottery of user-provided prizes. As the lottery information, for example, information input by each user through the premium setting screen is used. The lottery information includes, for example, information on a period for recruiting participants to the lottery, information on each item set as a user-provided prize, and information on a user who has set a user-provided prize. Therefore, for example, on the prize setting screen, these periods, items, and user information (such as a user ID or a card ID) are input. Note that the user information may be acquired based on authentication at the time of service provision. In this case, information for specifying each user such as a user ID or a card ID may not be input on the prize setting screen.

  In subsequent step S <b> 12, the Web service management unit 17 reflects the lottery information acquired in step S <b> 11 in the lottery data 23. Specifically, the lottery data 23 is updated (including generation of the lottery data 23) so that a record for managing a period, a prize, a user ID, and the like included in the lottery information is generated. That is, in step S12, the Web service management unit 17 newly generates a record to which a unique lottery ID is assigned by associating information such as a period, a premium, and a user ID. Further, the web service management unit 17 also updates the contents of the play data 24 so that the item provided as the prize is excluded from the possessed items of the user who provided the prize together with the update of the lottery data 23. Specifically, the item provided from the possessed item of the user ID included in the record generated in the lottery data 23 is deleted. That is, the item provided as a prize is deleted from the play data 24 of the user who provided the prize. Then, when the process of step S12 is completed, the Web service management unit 17 ends the current routine. The lottery data 23 is used to execute a prize lottery game. Specifically, the contents of the prize lottery game are guided and executed based on the contents of the lottery data 23. Therefore, according to the routine shown in FIG. 6, a prize lottery game in which a user's possessed item set through the prize setting screen is a lottery target is guided and executed.

  On the other hand, FIG. 7 is a diagram illustrating an example of a flowchart of a prize lottery processing routine. The routine of FIG. 7 is repeatedly executed at a predetermined cycle. For example, based on the status information included in the lottery data 23, the routine of FIG. 7 is executed only for records whose status information corresponds to the prize lottery game not being executed. Further, the routine of FIG. 7 is executed for each record of the lottery data 23.

  When the routine of FIG. 7 is started, first, in step S21, the Web service management unit 17 determines whether or not a predetermined period has passed based on the period information of the lottery data 23. If the determination result is a positive result, that is, if a predetermined period has elapsed, the Web service management unit 17 proceeds to step S22. In step S22, the Web service management unit 17 returns each premium including the target record to the providing user. Specifically, the Web service management unit 17 updates the content of the play data 24 so that each prize included in the target record is described again as a possessed item in the play data 24 of the user as the provider. In step S22, the Web service management unit 17 also executes a process of changing the status information of the lottery data 23 from not yet implemented. When the Web service management unit 17 finishes the process of step S22, the current routine ends.

  On the other hand, if the determination result in step S21 is a negative result, that is, if the predetermined period has not elapsed, the Web service management unit 17 proceeds to step S23. In step S23, the Web service management unit 17 determines whether or not the number of users who wish to participate in the lottery opportunity of the prize lottery game realized by the target record satisfies the target number. The target number of people corresponds to the number of prizes to be drawn. If the determination result is a negative result, that is, if the target number is insufficient, the Web service management unit 17 skips the subsequent processing and ends the current routine. Note that the lottery data 23 may separately include information indicating the target number of people. In this case, the determination in step S23 may be performed based on information indicating the target number of persons.

  On the other hand, if the determination result in step S23 is a positive result, that is, if the target number is satisfied, the Web service management unit 17 proceeds to step S24. In step S24, the Web service management unit 17 collects a consideration from each user who wishes to participate in a lottery opportunity based on the target record. The consideration may be provisionally collected when each user makes an intention to participate. Temporary collection means that a consideration is temporarily collected from each user. Accordingly, the provisionally collected consideration cannot be consumed by each user, but is not yet consumed. By performing provisional collection, it is possible to suppress a situation in which the user's consideration decreases from the participation intention display to the execution of the lottery and the collection becomes impossible. In this case, in step S24, consumption of the temporarily collected consideration is determined. If the consideration is provisionally collected, in the process of step S22, the Web service management unit 17 may execute a process for returning the consideration to each user of the provisional collection source.

  In subsequent step S25, a lottery for distributing each prize to be drawn to each user who participated in the lottery opportunity is performed. That is, in step S25, the Web service management unit 17 executes a lottery to determine to which user each prize to be lottery should be given. In the next step S26, the Web service management unit 17 gives each user a prize for each lottery based on the lottery result in step S25. Specifically, the Web service management unit 17 updates the content of the play data 24 so that each prize becomes an item possessed by each user, that is, added as a possession target. In the subsequent step S27, the web service management unit 17 gives a reward corresponding to the total consideration collected in step S25 to the user who provided each lottery prize. That is, for example, when a point corresponding to the total consideration is given as a reward, the Web service management unit 17 updates the content of the play data 24 so that the provision of the point is reflected. At this time, the Web service management unit 17 also executes a process of changing the status information of the lottery data 23 from not performing the prize lottery game to having been performed. When the process of step S27 is completed, the Web service management unit 17 ends the current routine. Thereby, when the target number of people gathers, the lottery for which the user-provided prize is a lottery object is executed, and the user-provided prize is given to each user according to the lottery result. On the other hand, when the target number of people is not gathered and a predetermined period has elapsed, each item set as a user-provided prize is returned to the providing user. In addition, collection of compensation and rewards associated with execution of the prize lottery game are also realized.

  As described above, according to this embodiment, the possessed item of each user is set as a lottery target as a privilege candidate of the prize lottery game through the prize providing service. Thereby, each user can dispose of the item etc. which became unnecessary usefully. Unnecessary items are given to other users through lottery. Therefore, the fluidity of unnecessary items can be improved. Thereby, game resources can be used effectively.

  In addition, since the prize candidates of the prize lottery game are determined by the user, the degree of freedom of the prize is higher than when the prize candidates are determined in advance. Therefore, the variation of the privilege obtained by lottery can be increased. In addition, a corresponding reward is given to a user who provides his / her possessed item as a prize candidate. Therefore, provision of a prize candidate can be promoted. In addition, provision of items and the like that meet the needs of other players is also encouraged.
