  In the quest mode, the game proceeds when the user clears the presented task (quest).

  In the gacha mode, information on the game content selected by lottery (gacha) is associated with the user identification information. Then, information on the game content associated with the user identification information is transmitted to the user's game device.

  In the following, “transmission of information about the game content associated with the user identification information to the user's game device” may be referred to as “given to the user”. The user can operate the game medium provided to the user in the virtual game space via the touch pad 350 (the operation unit 35).

  As shown in FIG. 3, in the gacha mode of the present embodiment, the user selects which of a normal lottery (“one gacha!”) And a continuous lottery (“10 gacha!”) Is to be executed. Can be.

  The normal lottery is a lottery in which one lottery is performed in response to one operation of the user. The continuous lottery is a lottery in which a predetermined number of lotteries (in this embodiment, ten lotteries) are continuously performed in response to one operation of the user.

  In the dress-up mode, the user can change the costume of the character (game medium) by performing an operation of selecting a costume (game medium).

  In the game of the present embodiment, the words spoken by the character according to the game situation change together with the appearance of the character according to the costume worn by the character.

<Description of game media>
The game medium exhibits an effect set in the game medium according to a user operation. Game media includes non-consumable game media and consumer game media.

  Then, a parameter indicating the rarity in the game (hereinafter, referred to as “rareness”) is set in the non-consumed game medium and the consumed game medium.

  The non-consumable game medium is a game medium that can be continuously used (does not disappear) in the virtual game space while the information on the non-consumable game medium is associated with the user identification information. However, if the non-consumable game media is discarded, transferred, or so-called combining by a user operation or the like, the non-consumable game media cannot be used (disappears) thereafter.

  The storage unit 21 and the network interface 22 are connected to the control unit 20 of the server device 2 via the bus 200.

  The control unit 20 controls the operation of the server device 2.

  The storage unit 21 mainly includes an HDD (Hard Disk Drive), a RAM (Random Access Memory), and a ROM (Read Only Memory).

  The storage unit 21 stores, for example, a distribution program and data for distributing a game program for executing a game played on the game device 3. The storage unit 21 stores a lottery list (gacha list) assigned to the user account information or the game account information.

  In the present embodiment, a lottery list (gacha list) is assigned to user account information. Hereinafter, in the present embodiment, the lottery list is referred to as a gacha list. The details of the gacha list will be described later.

  The network interface 22 is connected to the communication network 4 for transmitting and receiving data between the server device 2 and the game device 3.

<Functional Configuration of Control Unit 20 of Server Device 2>
As shown in FIG. 1, the control unit 20 of the server device 2 functions as a matching unit 201, a lottery execution unit 202, a list management unit 203, and a communication unit 204 by executing the computer program of the present invention.

<Description of Matching Means 201>
The matching unit 201 authenticates the user account using the user account information transmitted from the game device 3.

<Description of lottery execution means 202>
The lottery execution means 202 receives lottery request information from the game device 3 via the communication means 204 described later.

  Upon receiving the lottery request information, the lottery executing means 202 obtains the gacha list assigned to the user account information from the list management means 203.

  The gacha list includes information on a plurality of types of game media. The information on the game content includes information on the name of the game content, ability parameters, rarity, and effects exerted by use.

  Further, a selection ratio is set for each game content included in the gacha list. For example, in the initial gacha list shown in FIG. 2 (the initial gacha list will be described later), costume A and costume B are non-consumable game media, and the selection ratio is 20% each. Item A and item B are consumption game media, and the selection ratio is 5%.

  The lottery executing means 202 executes a lottery for selecting any game medium from the gacha list acquired from the list managing means 203 based on a selection ratio set for each game medium.

  Then, the lottery executing means 202 associates information on the game content selected by the lottery (hereinafter, referred to as “selected game content”) with the user account information. Information about the selected game content associated with the user account information is transmitted to the game device 3 via the communication unit 204.

  Thereby, the lottery executing means 202 gives the selected game content to the user.

<Description of List Management Unit 203>
When the lottery execution unit 202 receives the lottery request information, the list management unit 203 determines whether or not the storage unit 21 has a gacha list assigned to the user account information.

  When it is determined that there is no gacha list assigned to the user account information in the storage unit 21, the list management unit 203 assigns the initial gacha list to the user account information. The initial gacha list is a gacha list assigned to the user account information of the user when the lottery execution means 202 receives the first lottery request from the user.

  Then, the list management unit 203 causes the storage unit 21 to store the initial gacha list assigned to the user account information. At the same time, the list management unit 203 transmits the initial gacha list assigned to the user account information to the lottery execution unit 202.

  On the other hand, when it is determined that there is a gacha list assigned to the user account information in the storage unit 21, the list management unit 203 reads the gacha list. Then, the list management unit 203 transmits the gacha list read from the storage unit 21 to the lottery execution unit 202.

  After the lottery execution unit 202 executes the lottery, the list management unit 203 determines whether to update the gacha list according to the lottery result. The list management unit 203 updates the gacha list when the selected game medium is a non-consumable game medium.

  On the other hand, when the selected game medium is a consumption game medium such as the item A, the list management unit 203 does not update the gacha list. That is, in this case, all of the selection ratios set for the game contents included in the gacha list are not changed.

  FIG. 4 shows a game screen displayed on the liquid crystal screen 340 after the lottery performed using the initial gacha list shown in FIG.

  In the lottery shown in FIG. 4, costume A, which is a non-consumable game medium, is selected. Therefore, the list management unit 203 updates the gacha list assigned to the user account information.

  Specifically, as shown in FIG. 5, the list management unit 203 does not delete the costume A from the gacha list and changes the selection ratio set for the costume A from 20% to 1% (less than 20% and 0%). If the value is large, it is acceptable.) At the same time, the list management unit 203 increases the selection ratio set for other types of game media (for example, costume B, item A, and item B) included in the gacha list.

  Then, the list management unit 203 causes the storage unit 21 to store the updated gacha list assigned to the user account information.

<Description of Communication Means 204>
The communication unit 204 transmits and receives user account information, download request information, game programs, game account information, and game data such as billing to and from the game apparatus 3.

  Further, the communication unit 204 receives the lottery request information from the game device 3. The lottery request information received by the communication unit 204 is transmitted to the lottery execution unit 202.

  In addition, the communication unit 204 transmits to the game apparatus 3 the information on the game content that the lottery execution unit 202 gives to the user according to the lottery result.

<Hardware configuration of game device 3>
The game device 3 is, for example, a terminal device such as a smartphone in which the speaker 330, the liquid crystal screen 340, and the touch pad 350 are built as shown in FIG. In the game device 3, the game proceeds based on a game program and data relating to the game distributed from the server device 2.

The user touches the touch pad 350 to perform a lottery request, select a quest, or operate a player character.

<Functional Configuration of Control Unit 30 of Game Device 3>
As shown in FIG. 1, the control unit 30 of the game device 3 functions as a game execution unit 301, a lottery requesting unit 302, and a communication unit 303 by executing a game program downloaded from the server device 2.

<Description of the game execution means 301>
The game execution unit 301 causes the game device 3 to execute a game including a quest mode, a gacha mode, and a dress-up mode based on an operation of the touch pad 350 by the user.

  Specifically, the game executing means 301 reads out data such as a game space object and a texture included in the game data from the storage unit 31 and generates a two-dimensional or three-dimensional virtual game space.

  Further, the game executing means 301 arranges the player character in the virtual game space. Then, the game execution means 301 controls the action of the player character in the virtual game space according to the operation of the touch pad 350 by the user and the progress of the game.

  Further, the game executing means 301 selects the appearance of the player character displayed on the game screen 340 and the dialogue spoken by the player character according to the game situation, based on the costume worn by the player character.

  In addition, the game execution means 301 generates information for displaying the virtual game space, the player character, and the virtual operation buttons on the liquid crystal screen 340 as a game screen. The graphic processing unit 34 draws a game image on the liquid crystal screen 340 according to the information. For example, on the liquid crystal screen 340, as shown in FIG. 3, "user rank", "number of jewels", "an image for selecting one of the normal lottery and the continuous lottery" are displayed from the upper part of the screen.

  Specifically, as shown in FIG. 3, consuming 10 jewels requests execution of a normal lottery, or consuming 90 jewels executes a continuous lottery (10 consecutive gacha). The user can select whether to request the request.

<Description of Lottery Requesting Means 302>
The lottery requesting unit 302 makes a lottery request by consuming jewelry based on a user operation. When a lottery request for executing a normal lottery is made, the lottery requesting unit 302 generates lottery request information for executing a normal lottery.

  On the other hand, when a lottery request for executing a continuous lottery is made, the lottery requesting unit 302 generates lottery request information for executing a continuous lottery.

  The lottery request information is transmitted to the server device 2 via the communication unit 303.

<Description of Communication Means 303>
The communication unit 303 receives, for example, a game program related to a game, information related to a game content, and the like from the server device 2.

  In addition, the communication unit 303 transmits information such as user account information, game account information, download request information of new game data, and lottery request information to the server device 3 based on a user operation, for example.

<Description of gacha list update process>
Hereinafter, the gacha list update processing of the present invention will be described with reference to FIG. Note that the control means and the processing procedure described below are merely examples, and embodiments of the present invention are not limited to these. The design of the processing procedure and the like can be appropriately changed without changing the gist of the present invention.

  First, the lottery executing means 202 determines whether a lottery request from the lottery requesting means 302 has been received (step S1).

  When it is determined that the lottery request from the lottery requesting unit 302 has been received (S1: YES), the list management unit 203 determines whether there is a gacha list assigned to the user account information of the user who made the lottery request in the storage unit 21. It is determined whether or not it is (step S2).

  When it is determined that there is no gacha list assigned to the user account information in the storage unit 21 (S2: NO), the list management unit 203 assigns an initial gacha list to the user account information (step S3). Then, the list management unit 203 causes the storage unit 21 to store the initial gacha list assigned to the user account information. At the same time, the list management unit 203 transmits the initial gacha list assigned to the user account information to the lottery execution unit 202.

  On the other hand, when it is determined that there is a gacha list assigned to the user account information in the storage unit 21 (S2: YES), the list management unit 203 reads the gacha list (step S4). Then, the list management unit 203 transmits the gacha list read from the storage unit 21 to the lottery execution unit 202.

  Upon obtaining the gacha list assigned to the user account information from the list management means 203, the lottery executing means 202 selects any game content based on the selection ratio set for each game content included in the gacha list. A lottery is executed (step S5).

  Next, the lottery executing means 202 associates information on the game content (selected game content) selected by the lottery with the user account information. Then, the lottery execution means 202 transmits information on the selected game content to the game device 3 via the communication means 204. Thereby, the selected game content is provided to the user (step S6).

  Thereafter, the list management means 203 determines whether or not the selected game content is a non-consumable game content (Step S7).

  When it is determined that the selected game content is not a non-consumable game content (S7: NO), the list management unit 203 does not update the gacha list. That is, in this case, all of the selection ratios set for the game contents included in the gacha list are not changed. Thereafter, the gacha list update processing of the present invention ends.

  On the other hand, when it is determined that the selected game content is a non-consumable game content (S7: YES), the list management unit 203 updates the gacha list (step S8).

  Specifically, the list management unit 203 reduces the selection ratio set for the selected game medium without deleting information on the selected game medium from the gacha list. At the same time, the list management unit 203 increases the selection ratio set for another game content included in the gacha list.

  After that, the list management unit 203 causes the storage unit 21 to store the updated gacha list assigned to the user account information. Thereafter, the gacha list update processing of the present invention ends.

  Returning to step S1, if it is determined that the lottery request from the lottery requesting means 302 has not been received (S1: NO), the gacha list updating process of the present invention ends. With the above procedure, the gacha list updating process of the present invention is executed.

To summarize the above, the computer program of the present embodiment is:
Computer device (server device 2)
Upon receiving the lottery request from the user, one of the game contents is selected from a lottery list (gacha list) including information on a plurality of types of game contents based on a selection ratio set for each of the game contents. A lottery executing means 202 for executing a lottery and associating information relating to a game content selected by the lottery (hereinafter referred to as “selected game content”) with identification information (user account information) of the user; and the selected game content The list management unit 203 updates the gacha list by reducing the selection ratio set in the selected game medium without deleting information about the gacha list from the gacha list.

<Effect of the Invention>
According to the computer program of the present embodiment, it is possible to prevent the same game medium from being given to the user a plurality of times.

[Other embodiments]
In the above embodiment, an example has been described in which the list management unit updates the gacha list when the selected game medium is a non-consumable game medium, but the present invention is not limited to this.

  For example, when the rarity of the selected game medium is equal to or more than a predetermined value, the list management unit may update the gacha list.

  Alternatively, when the rarity of the selected game medium is equal to or less than a predetermined value, the list management unit may update the gacha list. At this time, when a low-rarity game content set with a high selection ratio is selected by lottery, the list management means may reduce the selection ratio of this game content.

  As a result, in the subsequent lottery, it is difficult to select the low-rare game medium, and the higher-rare game medium is more likely to be selected, so that the user can be more motivated to execute the lottery.

  As another example, the list management means may update the gacha list when the number of times the same game medium is selected by lottery reaches a predetermined number. For example, when the same game content is selected more than once, the list management means may reduce the selection ratio of the game content selected more than once.

  In addition, when the number of times that the same type of game medium is selected by lottery reaches a predetermined number, the list management unit may update the gacha list. In this case, when game contents of the same type (for example, game contents A) having different rarities are included in the gacha list, game contents A of different rarities may be selected redundantly, May be included when the number of times selected by the user has reached a predetermined number.

  As another example, the gacha list may be updated by the list management means regardless of which game content is selected.

  That is, regardless of which game content the selected game content is, the list management means reduces the selection ratio set for the selected game content without deleting the selected game content from the gacha list. At the same time, the list management means increases the selection ratio set for another game content included in the gacha list.

  At this time, another game content for which the selection ratio is increased may be selected by a lottery in the list management unit (this lottery is hereinafter referred to as an “updated lottery” to distinguish from the lottery in the lottery execution unit).

  Specifically, the list management means selects one or a plurality of game contents from the game contents other than the selected game contents among the game contents included in the gacha list by an update lottery. Then, the list management means increases the selection ratio set for the game content selected by the update lottery.

  The update lottery may be a random lottery or a lottery executed based on a selection ratio set for each game medium. An arbitrary lottery method can be adopted as a method of the update lottery.

  When a plurality of game contents are selected by the update lottery, an arbitrary distribution method can be adopted as to how to increase the selection ratio set for each game medium.

  For example, the list management means may increase the selection ratios by equally allocating the reduced selection ratios to the selection ratios set for the plurality of game media selected by the update lottery. .

  Alternatively, the list management means may increase the selection ratios by distributing the reduced selection ratios in accordance with the selection ratio ratios set for the plurality of game media selected by the update lottery. .

  Further, when the list management means selects another game content for which the selection ratio is to be increased, the game content whose selection ratio has been reduced once may be excluded from targets for which the selection ratio is to be increased. That is, the list management unit does not increase the selection ratio of the game content whose selection ratio has been reduced.

  As a result, for the same game content, the selection ratio may be increased twice or more, but once the selection ratio is decreased, the selection ratio is not increased thereafter. Therefore, the possibility that different game contents are given to the user is increased, and the possibility that the same game contents are given to the user is reduced.

  That is, it is possible to increase the possibility that all the game contents included in the gacha list can be acquired by the user repeatedly performing the lottery request. For this reason, the user can easily acquire the game content that the user wants to acquire.

  In the above embodiment, the list management unit does not delete the information on the selected game content from the gacha list, reduces the selection ratio set in the selected game content, and sets the other game media included in the gacha list. The example in which the gacha list is updated by increasing the set selection ratio has been described, but the present invention is not limited to this.

  For example, the list management unit decreases the selection ratio set in the selected game content (for example, reduces the selection ratio from 20% to 1%), and deletes another game content not included in the gacha list from which the lottery was executed. It may be newly included in the gacha list. Then, the list management unit sets the reduced selection ratio (for example, 19%) in another game medium that newly includes the selection ratio.

  At this time, the list management means may read out information on the game content associated with the user account information from the storage unit, and newly include the game content not associated with the user account information in the gacha list. The game media newly included may be one type or a plurality of types.

  When a plurality of game media are newly included, an arbitrary distribution method can be adopted as to how to set the selection ratio for each game media. For example, the list management means may set the selection ratios by equally allocating the reduced selection ratios to the respective game contents.

  By adding a game content of a type not owned by the user to the gacha list, motivation of the user to execute the lottery can be increased.

  Further, the list management means reduces the selection ratio set for the selected game medium. At the same time, the selection ratio set for another game content included in the gacha list and having the same attribute as the selected game content may be changed (decreased or increased).

  Here, the attribute may be, for example, an attribute of the character such as a fire attribute, a water attribute, or a wind attribute. Alternatively, the attribute may be an attribute included in the character, such as a physical strength attribute, an attack attribute, or a defense attribute. Further, the attribute may be a rarity. In this way, any category can be adopted as the attribute.

  When the list management means decreases the selection ratio set for the game content having the same attribute as the selected game content, the game content having another attribute is likely to be selected in the next lottery.

  For example, when one of the game contents with the fire attribute is selected by lottery, the list management unit decreases the selection ratio set for the game medium with the fire attribute included in the gacha list. At the same time, the list management means increases the selection ratio set for the water-based game media or the wind-based game media.

  Thus, in the next lottery, there is a high possibility that a water-based game medium or a wind-based game medium is selected.

  On the other hand, the case where the list management means increases the selection ratio set for the game content having the same attribute as the selected game content is as follows.

  For example, when one of the fire attribute game media is selected by lottery, the list management unit decreases the selection ratio set for the fire attribute game media selected by lottery. At the same time, the selection ratio set for the game contents having other fire attributes is increased.

  Thereby, in the next lottery, it is possible to increase the probability of winning a game medium having another fire attribute different from the game medium having the fire attribute selected in the previous lottery.

  Further, in this example, when game contents of the same type (for example, game contents A) having different rarities are included in the gacha list, when the game medium A having a low rarity is selected by lottery, the list management means becomes low. It is possible to reduce the selection ratio set for the game medium of the rarity and increase the selection ratio set for the game medium A of the high rarity.

  As another example, a plurality of patterns of gacha lists (for example, a first gacha list and a second gacha list) may be stored in the server device in advance. Then, the gacha list may be updated by the list management unit replacing the first gacha list assigned to the user account information with the second gacha list according to the lottery result.

  The second gacha list includes information on a game medium (selected game medium) selected by lottery from the first gacha list. Then, a selection ratio lower than the selection ratio set in the first gacha list is set for the selected game media included in the second gacha list.

  Thereby, the same effect as the invention described in the present embodiment can be obtained.

  Further, in the above-described embodiment, an example in which one of the normal lottery and the continuous lottery is executed has been described.

  For example, upon receiving a lottery request for executing a continuous lottery, the lottery executing means changes a gacha list (including an initial gacha list) assigned to the user account information of the user to a game included in the gacha list. The lottery is executed based on the selection ratio set for each medium.

  At this time, ten consecutive lotteries may be executed on the same gacha list. Alternatively, the gacha list update process may be performed every time after one lottery is executed, and the next lottery may be executed with the updated gacha list (or the gacha list at the time of executing the previous lottery if not updated).

  In the latter case, the following procedure may be employed. That is, when the first lottery is executed among the ten consecutive lotteries, the list management means determines whether to update the gacha list according to the lottery result.

  When it is determined that the gacha list is updated, the list management means updates the gacha list. Then, the lottery executing means executes the second lottery with the updated gacha list. According to this procedure, a series of processes of lottery and update are repeatedly executed ten times.

  The selected game content may be provided to the user each time one of the consecutive lotteries is executed. Alternatively, after ten consecutive lotteries are executed, ten selected game contents may be provided to the user at one time.

  Furthermore, when the continuous lottery is executed, a gacha list update process different from the normal lottery may be executed.

  For example, when the continuous lottery is executed, the selection ratio set for the non-consumable game medium may be more likely to be increased than when the normal lottery is executed. Furthermore, among the non-consumable game media, the selection ratio set for the non-consumable game media whose rarity is equal to or more than a predetermined value may be easily increased.

  Alternatively, when the continuous lottery is executed, the selection ratio set in the selected game medium may be greatly reduced as compared to when the normal lottery is executed. As a result, the selection ratio set for another game medium is greatly increased, so that another game medium is easily selected by the next lottery.

  Further, in the above embodiment, when the selected game medium is the costume A, the gacha list is updated by reducing the selection ratio set in the game medium from 20% to 1%. Is not limited to this.

  For example, the gacha list may be updated so that the selection ratio set for the selected game medium becomes extremely low. Specifically, the list management means may reduce the selection ratio from 20% to 0.01%.

  Thereby, it can be further suppressed that the same game content is given to the user a plurality of times.

  However, even in such a case, there is a considerable possibility that the same game medium (in this example, costume A) will be selected by lottery in the subsequent lottery.

  Therefore, in order to avoid discouraging a user who has been given the same game content a plurality of times, if the game content whose selection ratio has been reduced by the list management means is selected in the subsequent lottery, the selected game content is not selected. A predetermined privilege may be provided to the user together with the medium or instead of the selected game medium.

  The predetermined privilege includes, for example, a lottery ticket that allows a lottery request to execute a normal lottery or a continuous lottery without consuming jewelry. Alternatively, the predetermined privilege includes an exchange ticket that allows the user to freely select a game content that the user wants to acquire, or a high-rare game content.

  As another example, the gacha list may be updated so that the selection ratio set for the selected game medium is 0%. At this time, when the game contents included in the gacha list include only the consumption-based game contents, or when the game contents included in the gacha list are of one type, the list management unit does not update the gacha list. It may be.

  Further, in the above embodiment, an example in which the computer device is a server device is described, but the present invention is not limited to this. For example, a game device of one user may function as a server device. In this case, one game device and the other game device may be connected by BLUETOOTH (registered trademark).

  Further, in the embodiment, an example is described in which the game device is a terminal device such as a smartphone, but the present invention is not limited to this. The game device may be, for example, a stationary game device to which a display and a controller are externally connected, or a personal computer.
