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

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

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

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

  Further, 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, for example, a user operation.

<Description of Gacha list update process>
Hereinafter, the gacha list update process of the present invention will be described with reference to FIG. Note that the control means and the processing procedure described later are an example, and the embodiments of the present invention are not limited to these. The processing procedure and the like can be appropriately changed in design without departing from the scope of the present invention.

  First, the lottery execution unit 202 determines whether a lottery request from the lottery request unit 302 has been received (step S1).

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

  If 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 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 allocated 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 there is a gacha list assigned to the user account information in the storage unit 21 (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 unit 202 acquires the gacha list allocated to the user account information from the list management unit 203, the lottery execution unit 202 selects any game media based on the selection ratio set for each game medium included in the gacha list. A lottery is executed (step S5).

  Then, the lottery execution means 202 associates the information on the game medium (selected game medium) selected by the lottery with the user account information. Then, the lottery execution means 202 transmits information on the selected game medium to the game apparatus 3 via the communication means 204. Thereby, the selected game medium is given to the user (step S6).

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

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

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

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

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

  Returning to step S1, when it is determined that the lottery request from the lottery request means 302 has not been received (S1: NO), the gachalist update process of the present invention ends. According to 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),
In response to receiving a lottery request from the user, a game list is selected based on a selection ratio set for each of the game media from a lottery list (gacha list) including information on a plurality of types of game media. Lottery execution means 202 for executing lottery and associating information on the game medium (hereinafter referred to as “selected game medium”) selected by the lottery with identification information (user account information) of the user, and the selected game medium Function as list management means 203 for updating the gacha list by reducing the selection rate set in the selected game medium without deleting the information on the gacha list from the gacha list.

<Effect of the invention>
According to the computer program of the present embodiment, it is possible to suppress that the same game medium is provided to the user a plurality of times.

[Other embodiments]
In the above embodiment, when the selected game medium is a non-consumption 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 more 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, when a low rarity game medium to which a high selection rate is set is selected by lottery, the list management means may decrease the selection rate of the game medium.

  As a result, it becomes difficult to select this low rarity game medium in the next and subsequent lotterys, and it becomes easier to select a game medium with higher rarity than that, so it is possible to enhance the user's motivation for lottery execution.

  As another example, the list management means may update the gacha list when the number of times the same game medium has been selected by lottery becomes a predetermined number. For example, when the same game content is selected in duplicate, the list management means may reduce the selection ratio of the game content selected in duplicate.

  In addition, the list management means may update the gacha list when the number of times the same type of game media is selected by lottery becomes a predetermined number. In this case, when game media of the same type (for example, game media A) having different rarities are included in the gacha list, it is also possible that game media A having different rarities are redundantly selected, and the same type of game is drawn May be included in the case where the number of times selected by has become a predetermined number.

  As another example, even if the selected game medium is any game medium, updating of the gacha list by the list management means may be performed.

  That is, even if the selected game medium is any game medium, 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 rate set for other game media included in the Gacha list.

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

  Specifically, the list management means selects one or more game media from the game media other than the selected game media among the game media included in the gacha list by the update lottery. Then, the list management means increases the selection ratio set to the game medium selected by the update lottery.

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

  When there are a plurality of game media selected by the update lottery, any distribution method may be employed as to how to increase the selection ratio set for each game media.

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

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

  Also, when the list management means selects another game medium for which the selection rate is to be increased, game media for which the selection rate has been decreased may be excluded from targets for which the selection rate is to be increased. That is, the list management means does not increase the selection rate for game media for which the selection rate is reduced.

  Thus, although the selection rate may be increased twice or more for the same game medium, it is not increased after the selection rate is decreased once. Therefore, the possibility of giving different game media to the user is increased, and the possibility of giving the same game media to the user is reduced.

  That is, it is possible to increase the possibility that all game media included in the gacha list can be acquired by the user repeatedly making a lottery request. For this reason, the user can easily acquire the game medium that he / she wants to acquire.

  Further, in the above embodiment, the list management means reduces the selection rate set in the selected game medium without deleting the information on the selected game medium from the gacha list, and the other game medium included in the gacha list. Although the example which updates a gacha list by increasing the set selection ratio was shown, this invention is not limited to this.

  For example, the list management means decreases the selection rate set in the selected game medium (for example, reduces it from 20% to 1%), and other game media not included in the gachaslist for which the lottery has been performed. You may newly include it 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 out the information on 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 game media to be newly included may be one type or a plurality of types.

  In the case where there are a plurality of game media to be newly included, any distribution method may be employed as to how to set the selection ratio to each game media. For example, the list management means may set these selection rates by equally distributing the reduced selection rates to each game medium.

  By newly including game media of a type not owned by the user in the gacha list, it is possible to enhance the user's motivation for the lottery execution.

  Also, the list management means decreases the selection rate set in the selected game medium. At the same time, it is also possible to change (decrease or increase) the selection rate set for game media having the same attribute as the selected game media, which is another game media included in the Gacha list.

  Here, the attribute may be, for example, an attribute of a character such as a fire attribute, a water attribute, or a wind attribute. Alternatively, the attribute may be an attribute that the character has, such as a strength attribute, an attack attribute, or a defense attribute. Furthermore, the attribute may be rarity. Thus, any category can be adopted as an attribute.

  When the list management means decreases the selection rate set for game media having the same attribute as the selected game media, game media having other attributes are more likely to be selected in the next lottery.

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

  This increases the possibility that the game medium of the water attribute or the game medium of the wind attribute is selected in the next lottery.

  On the other hand, when the list management means increases the selection ratio set to the game medium having the same attribute as that of the selected game medium, the following occurs.

  For example, when any game medium of the fire attribute is selected by lottery, the list management means decreases the selection ratio set to the game medium of the fire attribute selected by the lottery. At the same time, the selection rate set for game media of other fire attributes is increased.

  Thereby, in the next lottery, it is possible to increase the winning probability of the game media of the other fire attribute different from the game media of the fire attribute selected in the previous lottery.

  Further, in this example, when the same kind of game media (for example, game media A) having different rarities are included in the gacha list, when the game media A of low rarity is selected by lottery, the list management means is low It is possible to decrease the selection rate set in the rarity game medium and increase the selection rate set in the high rarity game medium A.

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

  The second gacha list includes information on game media (selected game media) 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 this embodiment can be obtained.

  Moreover, in the said embodiment, although the example in which either normal lottery or continuous lottery was performed was shown, the following structure may be employ | adopted, when continuous lottery is performed.

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

  At this time, ten consecutive lottery may be executed on the same gacha list. Alternatively, the gachas list updating process may be performed every time after the execution of one lottery, and the next lottery may be performed on the updated gachas list (in the case of not updating, the gachaslist at the time of the previous lottery execution).

  In the latter case, the following procedure may be employed. That is, when the first lottery is executed among the 10 consecutive lotterys, the list management means determines whether to update the gachaslist 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 unit executes the second lottery with the updated gacha list. By this procedure, a series of lottery and update processes are repeatedly executed ten times.

  The selected game medium may be given to the user each time one lottery in the continuous lottery is performed. Alternatively, ten selected game media may be given to the user at one time after ten consecutive lottery runs.

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

  For example, when the continuous lottery is performed, the selection ratio set to the non-consumer-based game medium may be easily increased as compared to the time when the normal lottery is performed. Furthermore, among non-consumption game media, the selection ratio set for non-consumption game media having rarity greater than or equal to a predetermined value may be easily increased.

  Alternatively, when the continuous lottery is performed, the selection ratio set in the selected game medium may be greatly reduced compared to when the normal lottery is performed. As a result, since the selection ratio set for the other game media is greatly increased, the other game media can be easily selected by the next lottery.

  Further, in the above embodiment, when the selected game medium is the costume A, the example has been described in which the gachalist is updated by reducing the selection rate set in the game medium from 20% to 1%. Is not limited to this.

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

  Thereby, it is possible to further suppress that the same game medium is provided 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, the costume A) will be selected by the next lottery.

  For this reason, in the case where a game medium whose selection ratio is reduced by the list management means is selected in the next and subsequent lotterys in order not to discourage the user given the same game medium a plurality of times, the selected game is selected. A predetermined benefit may be given to the user along with the medium or in place of the selected game medium.

  The predetermined benefit includes, for example, a lottery ticket which can make a lottery request for executing a normal lottery or a continuous lottery without consuming a jewel. Alternatively, the predetermined benefits include a replacement ticket which allows the user to freely select a game medium that the user wants to acquire, or a game medium with high rarity.

  As another example, the gacha list may be updated such that the selection rate set for the selected game medium is 0%. At this time, when the game media included in the gachas list is only the consumption game media, or when the game media included in the gachas list is one type, the list management means does not update the gachas list You may

  Further, although an example in which the computer device is a server device is described in the above embodiment, 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).

  Moreover, in the said embodiment, although the example which is a terminal device, such as a smart phone, is described, this 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.
