[Embodiment]
The game system 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 6. As shown in FIG. 1, the game system 1 includes a server device 2 and a game device 3.

<Game description>
The server device 2 provides the following game to be executed by the game device 3. Specifically, the game device 3 executes a predetermined game operated by the user via the touch pad 350.

In the present embodiment, the game executed by the game device 3 includes a quest mode, a gacha mode, and a dress-up mode.

In the quest mode, the game progresses by clearing the task (quest) presented by the user.

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

In the following, "the information about the game medium associated with the user's identification information is transmitted to the user's game device" may be referred to as "giving to the user". The user can operate the game medium provided to the user in the virtual game space via the touch pad 350 (operation unit 35).

As shown in FIG. 3, in the gacha mode of the present embodiment, the user selects whether to execute a normal lottery (“1 time gacha!”) Or a continuous lottery (“10 times gacha!”). Can be done.

The normal lottery is a lottery in which one lottery is performed according to one operation of the user. The continuous lottery is a lottery in which a predetermined number of lottery (10 lottery in the present embodiment) is continuously performed according to one operation of the user.

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

In the game of the present embodiment, the appearance of the character and the dialogue that the character utters according to the game situation change according to the costume worn by the character.

<Explanation of game media>
The game medium exerts the effect set in the game medium according to the operation of the user. Game media include non-consumer game media and consumer game media.

Then, a parameter indicating the rarity in the game (hereinafter, referred to as "rareity") is set in the non-consumer game medium and the consumer 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 about the non-consumable game medium and the user's identification information are associated with each other. However, if the non-consumable game medium is destroyed, transferred, or so-called synthesized by the user's operation, the non-consumable game medium cannot be used (disappears) thereafter.

As an example of a non-consumable game medium, there is a character (character card in a card game) in which ability parameters such as physical strength, offensive power, and defensive power are set according to rarity.

Another example of a non-consumable game medium is a costume or equipment in which the effect of its use is reflected in the character's appearance or ability parameters. In this embodiment, a non-consumer game medium will be described as a costume.

In contrast to non-consumer game media, consumer game media are game media that disappear after exerting their effects.

Consumable game media include, for example, healing agents, spawn rate increasing items or gems.

A healing drug is an item that restores a character's health parameters. The healing agent may also be an item that restores the stamina parameters required to perform a quest in quest mode.

The appearance rate increase item is an item that makes it easy for a high rarity game medium to be selected by lottery in the gacha mode.

A jewel is an item (so-called chargeable item) consumed to execute a lottery (gacha) in the gacha mode.

Jewels are given to the user according to the game progress (game result) in the quest mode. In addition, the jewel may be given to the user by purchasing it by a predetermined billing process, or by a login bonus in which the privilege given to the user is determined according to the number of times the game is logged in.

Some game media are given to the user only according to the progress of the game in the quest mode, and some are given to the user only according to the lottery result in the gacha mode. In addition, some game media are given to the user in both quest mode and gacha mode.

<Hardware configuration and functional configuration>
With reference to FIG. 1, the hardware configuration and functional configuration of the server device 2 and the hardware configuration and functional configuration of the game device 3 on which the game is executed will be described.

A user account is assigned to the game device 3 in association with the game device 3. This user account is managed as user account information (user identification information).

When the game device 3 communicates with the server device 2 via the communication network 4, the user account information is transmitted from the game device 3. The transmitted user account information is subjected to predetermined authentication in the server device 2. As a result, communication between the server device 2 and the game device 3 becomes possible.

In addition, the user is given a game account when playing the game. The game account is managed as game account information.

<Hardware configuration of server device 2>
As shown in FIG. 1, the server device 2 includes a control unit 20, a storage unit 21, and a network interface 22.

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 is mainly composed of 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. Further, 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, the lottery list (gacha list) is assigned to the user account information. Hereinafter, in the present embodiment, the lottery list will be 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 in order to send and receive data between the server device 2 and the game device 3.

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

<Explanation of collation means 201>
The collation means 201 authenticates the user account by using the user account information transmitted from the game device 3.

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

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

The gachalist contains information about multiple types of game media. Information about the game medium includes information about the name of the game medium, ability parameters, rarity, and effects exerted by use.

In addition, the selection ratio is set for each game medium 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-consumer game media, and the selection ratio is 20% each. Item A and item B are consumer game media, and the selection ratio is 5% each.

The lottery execution means 202 executes a lottery to select one of the game media from the gacha list acquired from the list management means 203 based on the selection ratio set for each game medium.

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

As a result, the lottery execution means 202 gives the user the selected game medium.

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

When it is determined that the storage unit 21 does not have the gacha list assigned to the user account information, the list management means 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 means 203 stores the initial gacha list assigned to the user account information in the storage unit 21. At the same time, the list management means 203 transmits the initial gacha list assigned to the user account information to the lottery execution means 202.

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

Further, the list management means 203 determines whether or not to update the gacha list according to the lottery result after the lottery is executed by the lottery execution means 202. The list management means 203 updates the gacha list when the selected game medium is a non-consumer game medium.

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

FIG. 4 is a game screen displayed on the liquid crystal screen 340 after the lottery is executed 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 means 203 updates the gacha list assigned to the user account information.

Specifically, as shown in FIG. 5, the list management means 203 does not delete the costume A from the gacha list, and sets the selection ratio of the costume A to 20% to 1% (less than 20% and less than 0%). If it is a large value, it is acceptable.) At the same time, the list management means 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 means 203 stores the updated gacha list assigned to the user account information in the storage unit 21.

<Explanation of communication means 204>
The communication means 204 transmits and receives user account information, download request information, game programs, game account information, game data such as billing, and the like to and from the game device 3.

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

Further, the communication means 204 transmits to the game device 3 information about the game medium that the lottery execution means 202 gives to the user according to the lottery result.

<Hardware configuration of game device 3>
As shown in FIG. 1, the game device 3 is a terminal device such as a smartphone, which incorporates a speaker 330, a liquid crystal screen 340, and a touch pad 350. In the game device 3, the game progresses based on the game program and data related to the game distributed from the server device 2.

Further, the game device 3 can perform data communication with the server device 2 via a communication network 4 such as the Internet or a LAN.

The game device 3 includes a control unit 30, a storage unit 31, a network interface 32, an audio processing unit 33, a graphic processing unit 34, and an operation unit 35.

The storage unit 31, the network interface 32, the audio processing unit 33, the graphic processing unit 34, and the operation unit 35 are connected to the control unit 30 via the bus 300.

The control unit 30 controls the operation of the game device 3.

The storage unit 31 is mainly composed of an HDD, a RAM, and a ROM. The storage unit 31 stores, for example, a game program and data for executing a game.

The network interface 32 is connected to the communication network 4 in order to send and receive data between the game device 3 and the server device 2. As a result, the game program and game data are downloaded to the game device 3.

The game image drawn in the moving image format by the graphic processing unit 34 is displayed on the liquid crystal screen 340 as a game screen.

An operation signal from the user is input to the operation unit 35. In the present embodiment, an operation signal from the user is input to the operation unit 35 via the touch pad 350, which is an input position detection device. By touching the touch pad 350, the user performs a lottery request, a quest selection, a player character operation, or the like.

<Functional configuration of the control unit 30 of the game device 3>
As shown in FIG. 1, the control unit 30 of the game device 3 functions as the game execution means 301, the lottery request means 302, and the communication means 303 by executing the game program downloaded from the server device 2.

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

Specifically, the game execution means 301 reads data such as game space objects and textures included in the game data from the storage unit 31 to generate a two-dimensional or three-dimensional virtual game space.

Further, the game execution means 301 arranges a player character in the virtual game space. Then, the game execution means 301 controls the behavior 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 execution means 301 selects the appearance of the player character displayed on the game screen 340 and the dialogue that the player character utters according to the game situation, based on the costume worn by the player character.

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

Specifically, as shown in FIG. 3, it is required to execute a normal lottery by consuming 10 jewels, or a continuous lottery (10 consecutive gachas) is executed by consuming 90 jewels. The user can choose whether to request that.

<Explanation of lottery request means 302>
The lottery requesting means 302 consumes jewels and makes a lottery request based on the user's operation. When a lottery request for executing a normal lottery is made, the lottery requesting means 302 generates lottery request information for executing the normal lottery.

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

These lottery request information is transmitted to the server device 2 via the communication means 303.

<Explanation of communication means 303>
The communication means 303 receives, for example, a game program related to a game, information about a game medium, and the like from the server device 2.

Further, the communication means 303 transmits information such as user account information, game account information, new game data download request information, and lottery request information to the server device 3 based on the user's operation, for example.

<Explanation of gachalist update process>
Hereinafter, the gachalist update process of the present invention will be described with reference to FIG. The control means and the processing procedure described later are examples, and the embodiments of the present invention are not limited thereto. 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 or not the lottery request from the lottery requesting means 302 has been accepted (step S1).

When it is determined that the lottery request from the lottery request means 302 has been accepted (S1: YES), does the list management means 203 have 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 (step S2).

When it is determined that the storage unit 21 does not have the gacha list assigned to the user account information (S2: NO), the list management means 203 assigns the initial gacha list to the user account information (step S3). Then, the list management means 203 stores the initial gacha list assigned to the user account information in the storage unit 21. At the same time, the list management means 203 transmits the initial gacha list assigned to the user account information to the lottery execution means 202.

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

When the lottery execution means 202 acquires the gacha list assigned to the user account information from the list management means 203, the lottery execution means 202 selects one of the game media based on the selection ratio set for each game medium included in the gacha list. The lottery is executed (step S5).

Next, the lottery execution means 202 associates the information about the game medium (selected game medium) selected by the lottery with the user account information. Then, the lottery execution means 202 transmits information about the selected game medium to the game device 3 via the communication means 204. As a result, the selected game medium is given to the user (step S6).

After that, the list management means 203 determines whether or not the selected game medium is a non-consumer game medium (step S7).

When it is determined that the selected game medium is not a non-consumer game medium (S7: NO), the list management means 203 does not update the gacha list. That is, in this case, all the selection ratios set for the game medium included in the gacha list are not changed. After that, the gachalist update process of the present invention ends.

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

Specifically, the list management means 203 reduces the selection ratio set in the selected game medium without deleting the information about the selected game medium from the gacha list. At the same time, the list management means 203 increases the selection ratio set for other game media included in the gacha list.

After that, the list management means 203 stores the updated gacha list assigned to the user account information in the storage unit 21. After that, the gachalist update process of the present invention ends.

Returning to step S1, when it is determined that the lottery request from the lottery requesting means 302 is not accepted (S1: NO), the gachalist update process of the present invention ends. By the above procedure, the gachalist update process of the present invention is executed.

To summarize the above, the computer program of this embodiment is
Computer device (server device 2),
When the user accepts the lottery request, one of the game media is selected from the lottery list (gacha list) containing information on a plurality of types of game media based on the selection ratio set for each game medium. A lottery execution means 202 that executes a lottery and associates information about a game medium selected by the lottery (hereinafter, referred to as "selected game medium") with identification information (user account information) of the user, and the selected game medium. It functions as a list management means 203 for updating the gacha list by reducing the selection ratio set in the selected game medium without deleting the information about the game from the gacha list.

<Effect of 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, when the selected game medium is a non-consumer game medium, the list management means updates the gacha list, but the present invention is not limited to this.

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

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

As a result, it becomes difficult to select the low rarity game medium in the next and subsequent lottery, and it becomes easier to select the high rarity game medium, so that the user's motivation for executing the lottery can be increased.

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 of times. For example, when the same game medium is selected more than once, the list management means may reduce the selection ratio of the duplicately selected game media.

Further, when the number of times the same type of game medium is selected by lottery reaches a predetermined number of times, the list management means may update the gacha list. In this case, when the same type of game media (for example, game media A) having different rarities are included in the gacha list, the same type of games may be drawn even if the game media A having different rarities are selected in duplicate. It may be included when the number of times selected by is the predetermined number of times.

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

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

At this time, another game medium that increases the selection ratio may be selected by a lottery in the list management means (this lottery is distinguished from the lottery in the lottery execution means, and is hereinafter referred to as "update lottery").

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

The renewal lottery may be a random lottery or a lottery executed based on a selection ratio set for each game medium. Any lottery method may be adopted as the method of the renewal lottery.

When there are a plurality of game media selected by the renewal lottery, an arbitrary allocation method may be adopted as to how to increase the selection ratio set for each game medium.

For example, the list management means may increase these selection ratios by evenly distributing the reduced selection ratios to the selection ratios set in the plurality of game media selected by the update lottery. ..

Alternatively, the list management means may increase these selection ratios by distributing the reduced selection ratios according to the ratios of the selection ratios set in the plurality of game media selected by the update lottery. ..

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

As a result, the selection ratio of the same game medium may be increased twice or more, but once the selection ratio is decreased, it is not increased thereafter. Therefore, the possibility that different game media are given to the user is increased, and the possibility that the same game medium is given to the user is low.

That is, it is possible to increase the possibility that the user can acquire all the game media included in the gacha list by repeatedly making the lottery request. Therefore, the user can easily acquire the game medium to be acquired.

Further, in the above-described embodiment, the list management means reduces the selection ratio set in the selected game medium without deleting the information about the selected game medium from the gacha list, and also causes other game media included in the gacha list. An example of updating the gacha list by increasing the set selection ratio has been shown, but the present invention is not limited to this.

For example, the list management means reduces the selection ratio set for the selected game medium (for example, from 20% to 1%), and also reduces other game media that were not included in the gachalist that executed the lottery. It may be newly included in the gacha list. Then, the list management means sets the reduced selection ratio (for example, 19%) to another game medium newly included.

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

When there are a plurality of game media to be newly included, an arbitrary allocation method may be adopted for how to set the selection ratio for each game medium. For example, the list management means may set these selection ratios by evenly distributing the reduced selection ratios to each game medium.

By newly including the types of game media that the user does not own in the gacha list, it is possible to increase the motivation of the user to execute the lottery.

In addition, the list management means reduces the selection ratio set in the selected game medium. At the same time, the selection ratio set for other game media included in the gacha list and having the same attributes as the selected game medium may be changed (decreased or increased).

Here, the attribute may be an attribute included in 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. In addition, the attribute may be rarity. In this way, any category can be adopted as the attribute.

When the list management means reduces the selection ratio set for the game medium having the same attributes as the selected game medium, the game medium having other attributes is likely to be selected in the next lottery.

For example, when any of the game media of the fire attribute is selected by the lottery, the list management means reduces the selection ratio set for the game medium of the fire attribute included in the gacha list. At the same time, the list management means increases the selection ratio set for the water attribute game medium or the wind attribute game medium.

As a result, there is a high possibility that the water attribute game medium or the wind attribute game medium will be selected in the next lottery.

On the other hand, when the list management means increases the selection ratio set in the game medium having the same attributes as the selected game medium, it is as follows.

For example, when any of the game media having the fire attribute is selected by the lottery, the list management means reduces the selection ratio set for the game medium having the fire attribute selected by the lottery. At the same time, the selection ratio set for other fire-type game media is increased.

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

Further, in this example, when the same type of game media (for example, game media A) having different rarities are included in the gacha list, when the low rarity game media A is selected by lottery, the list management means is low. The selection ratio set for the rarity game medium A can be decreased, and the selection ratio set for the high rarity game medium A can be increased.

As another example, a plurality of patterns of gachalists (for example, a first gachalist and a second gachalist) may be stored in advance in the server device. Then, the gacha list may be updated by the list management means 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 the 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 medium included in the second gacha list.

As a result, the same effect as that of the invention described in the present embodiment can be obtained.

Further, in the above-described embodiment, an example in which either the normal lottery or the continuous lottery is executed is shown, but when the continuous lottery is executed, the following configuration can be adopted.

For example, the lottery execution means receives a lottery request to execute a continuous lottery, and from the gacha list (including the initial gacha list) assigned to the user account information of the user, the game included in the gacha list. The lottery is executed based on the selection ratio set for each medium.

At this time, 10 consecutive lottery may be executed by the same gachalist. Alternatively, the gacha list update process may be performed each time after the execution of one lottery, and the next lottery may be executed by the updated gacha list (if not updated, the gacha list at the time of the previous lottery execution).

In the latter case, the following procedure may be adopted. That is, when the first lottery is executed out of the ten consecutive lottery, the list management means determines whether or not to update the gacha list according to the lottery result.

If it is decided to update the gacha list, the list management means updates the gacha list. Then, the lottery execution means executes the second lottery with the updated gachalist. According to this procedure, a series of lottery and update processes are repeated 10 times.

The selected game medium may be given to the user each time one of the continuous lottery is executed. Alternatively, after 10 consecutive lottery executions, 10 selected game media may be given to the user at one time.

Further, 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 in the non-consumer game medium may be more likely to be increased than when the normal lottery is executed. Further, among the non-consumable game media, the selection ratio set for the non-consumer game medium whose rarity is equal to or higher 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 significantly reduced as compared with the case where the normal lottery is executed. As a result, the selection ratio set for the other game medium is greatly increased, so that the other game medium is easily selected by the lottery in the next lottery.

Further, in the above-described embodiment, when the selected game medium is costume A, an example of updating the gachalist by reducing the selection ratio set in the game medium from 20% to 1% is shown. Is not limited to this.

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

As a result, it is possible to further prevent the same game medium from being given to the user multiple times.

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

Therefore, in order not to discourage the user who has been given the same game medium multiple times, if the game medium whose selection ratio has been reduced by the list management means is selected in the next and subsequent lottery, the selection game A predetermined privilege may be given to the user together with the medium or in place of the selected game medium.

Predetermined benefits include, for example, a lottery ticket that allows a lottery request to perform a regular lottery or a continuous lottery without consuming jewels. Alternatively, the predetermined privilege includes an exchange ticket in which the user can freely select the game medium to be acquired, or a highly rare game medium.

As another example, the gacha list may be updated so that the selection ratio set in the selected game medium becomes 0%. At this time, when the game medium included in the gacha list is only the consumer game medium, or when the game medium included in the gacha list is one type, the list management means does not update the gacha list. You may do it.

Further, in the above-described 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, one user's game device 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 above-described embodiment, an example in which the game device is a terminal device such as a smartphone is described, 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.
