Description

The present invention relates to a game program and a game system having a function of selectively deleting a game medium.

In some games, a user acquires a game medium (so-called "item") while the game is in progress and consumes it to advance the game. As a method of acquiring this game medium, for example, Patent Document 1 discloses a method using a mechanism called a gacha. The gacha is a mechanism in which a lottery is performed for a plurality of game media based on a predetermined lottery probability, and an arbitrary game medium selected by the lottery is given to the user. This gacha has the gambling property of a lottery.

Japanese Unexamined Patent Publication No. 2018-051219

Usually, there are two types of gacha, one is to draw a lottery for free (so-called "drawing a gacha"), and the other is to draw a gacha for a fee by paying some price such as billing. For paid gachas, users may be able to draw gachas an unlimited number of times as long as they pay.

However, in such a paid gacha, as a result of repeated billing until the user can acquire the desired game medium, the billing becomes high and the gacha's interest may be lost.

On the other hand, if only free gachas are used, the chances of drawing gachas are limited, and the probability of obtaining a desired game medium is reduced, which may result in dissatisfaction with the user.

An object of the present invention is to provide a game program and a game system in which a user can draw a gacha with peace of mind without inciting gambling.

The first invention is a computer.
A game medium lottery means for drawing any one or more game media from a lottery list including a plurality of game media related to a game based on a user's operation.
Before the lottery by the game medium lottery means is performed, it is made to function as a game medium selection means for selecting a specific game medium which is a specific game medium from the lottery list based on a user's operation.
The game medium lottery means is a game program characterized in that, when the specific game medium is selected by lottery, the lottery is repeated until the game medium other than the specific game medium is selected.

The second invention is
It is a game system including a storage unit that stores the game program of the first invention and a computer that executes the game program.

According to the present invention, it is possible to select from the lottery list not to acquire a specific game medium that the user does not want to acquire, for example, before drawing a gacha, based on the operation of the user. Even if the specific game medium is drawn, the lottery is repeated until the game medium is drawn. Therefore, since the probability that the user can acquire the desired game medium is substantially increased, the user can draw the gacha with peace of mind without inciting gambling. Therefore, the fun of gacha is improved.

Point a8 is also displayed on the game image. The user can select the payment method of the price from these.

By the user's operation, the game medium that the user wants to delete is selected from the touch pad 63, and when it is input that the price for deleting the game medium is to be paid, the game medium deleting means 235 of the server device 2 is selected. The game medium (corresponding to a specific game medium) is deleted from the lottery list. After that, the lottery list after the deletion process is transmitted to the game device 5.

FIG. 5 shows a lottery image a displayed on the display 61 after the specific game medium has been deleted from the lottery list. The lottery image a indicates that the number of game media in the lottery list is reduced by the number of specific game media deleted from the lottery list, according to the items a2, a2, ... a2 in the housing a1 and the quantity information a3. Shown.

On the other hand, on the screen of FIG. 3, when the "draw gacha" button a4 is selected from the touch pad 63 by the user's operation, the lottery list stored in the storage unit 22 by the game medium lottery means 233, that is, the deletion process is performed. Any game medium is drawn from the lottery list that has not been drawn. The lottered game medium is transmitted to the game device 5 by the distribution means 236 and stored in the storage unit 55. As shown in FIG. 7, the notification means 565 notifies the display 61 and the speaker 62 of the transmitted game medium.

<About the flow of processing performed by the server device 2 and the game device 5>
The flow of processing performed by the server device 2 and the game device 5 described above will be described with reference to FIGS. 2 to 7.

When a lottery event occurs during the progress of the game, the distribution means 236 transmits the information to the game device 5 (# 1). Further, the game medium lottery means 233 arbitrarily selects a plurality of game media and stores the selected game media as a lottery list in the storage unit 22 (# 2).

The game device 5 that has received the information of the lottery event notifies the information content by the display 61 and / or the speaker 62 (# 3).

For example, as shown in FIG. 3, the game device 5 that has received the above information displays the lottery image a on the display 61. The user can select the "draw gacha" button a4 or the "delete item" button a5 on the lottery image a (# 4).

Here, when the "delete item" button a5 is selected by the user's operation (YES in # 4), the instruction acquisition means 563 generates a deletion request to delete the game medium, and via the communication means 561. And sends it to the server device 2 (# 5).

Next, the price calculation means 234 of the server device 2 executes the deletion process of the game medium by the type and quantity of the game medium or the game medium deletion means 235 for each game medium of the lottery list stored in the storage unit 22. Based on the number of times, the price required for deletion is calculated (# 7).

Further, the price calculation means 234 transmits the calculated price information to the game device 5 via the distribution means 236 (# 8). The game device 5 (# 9) that has received the price information displays the price information on the display 61.

For example, as shown in FIG. 4, a plurality of game media (items) to be deleted are displayed (items A to C in FIG. 4), and price information required for deletion is displayed for each game medium (item). .. In FIG. 4, the billing amount a6, the game medium (item) a7, and the points a8 are displayed.

Here, the user selects the game medium to be deleted by operating the touch pad 63 (# 10), further selects payment of the price (# 11), and deletes the game medium (in FIG. 4). When the "delete execution" button a9) is input, the game medium selection means 564 outputs an instruction to the instruction acquisition means 563 to generate a payment request for the price and a deletion request for the game medium selected by the user. The instruction acquisition means 563 transmits these requests to the server device 2 via the communication means 561 (# 12).

After receiving the above request, the game medium deletion means 235 of the server device 2 confirms that the payment of the price has been performed properly (for example, confirms that the billing process has been performed properly), and then # 10. The game medium selected in step 2 is deleted from the lottery list of the storage unit 22 as a specific game medium (# 13).

Further, the game medium deletion means 235 transmits the update information of the lottery list stored in the storage unit 22 after the game medium deletion process described above to the game device 5 via the distribution means 236 (# 14). Here, the update information of the lottery list includes the number of game media in the storage unit 22 after the deletion process.

The game device 5 that has received the above update information continues to display the lottery gacha image on the display 61 (# 15). Since the specific game medium has been deleted, for example, as shown in FIG. 5, the items a2, a2, ... A2 and the quantity information a3 in the housing a1 are less than before the specific game medium was deleted. Is displayed.

Here, the user can select the "pull gacha" button a4 or the "delete item" button a5 again (# 16). It is assumed that the user inputs the "delete item" button a5 via the touch pad 63 of the game device 5 (YES in # 16). Then, the instruction acquisition means 563 sends the deletion request of the game medium to the server device 2 via the communication means 561 (# 5). After that, # 6 and subsequent steps are repeated in the same manner as above, but the price, etc. required for the deletion process for the game medium in the lottery list is calculated again by the price calculation means 234, and the price is different from the first time as shown in FIG. Is displayed on the display 61. FIG. 6 shows a selection screen for the second payment after deleting the “item A” for the first time in FIG.

On the other hand, it is assumed that the user inputs the "pull gacha" button a4 via the touch pad 63 of the game device 5 (NO in # 16). Then, the instruction acquisition means 563 generates a download request for the game medium, and the communication means 561 transmits this to the server device 2 (# 17).

Similarly, in step # 4, when the "do not delete the game medium", that is, the "pull the gacha" button a4 is selected by the user's operation (NO in step # 4), the instruction acquisition means 563 is the game medium. A download request is generated, and the communication means 561 transmits this to the server device 2 (# 17).

In this case, the game medium lottery means 233 of the server device 2 selects an arbitrary game medium from the lottery list stored in the storage unit 22 based on a certain lottery probability (# 18). That is, if the specific game medium is deleted, the lottery is performed from the deleted lottery list. If the specific game medium has not been deleted, a lottery is performed from the lottery list for which the deletion process has not been performed.

When the lottery is performed by the game medium lottery means 233, the game medium deletion means 235 deletes the game medium selected by the lottery from the lottery list.

Next, the distribution means 236 transmits the selected game medium and the updated lottery information to the game device 5 (# 19), and the game medium is stored in the storage unit 55 of the game device 5. The notification means 565 notifies the game medium to the display 61 and / or the speaker 62 as shown in FIG. 7 (# 20).

If the user subsequently inputs via the touchpad 63 that he / she wishes to continue the lottery (YES in # 21), the selection screens of the "draw gacha" button a4 and the "delete item" button a5 are displayed again. It is displayed (# 4). After that, # 4 and subsequent steps are repeated.

Summarizing the above, in the game program of the present embodiment, the control unit 23 (computer) of the server device 2 is set to any one or more from a lottery list including a plurality of game media related to the game based on the operation of the user. The game medium lottery means 233 for drawing the game medium and the game medium deletion process for deleting the specific game medium selected by the user's operation before the lottery by the game medium lottery means 233 is performed from the lottery list. In addition to functioning as means 235, the control unit 56 (computer) of the game device 5 functions as game medium selection means 564 for selecting the specific game medium to be deleted by the game medium deletion means 235 from the lottery list. It is a thing.

<Effect of invention>
According to the game program of the present embodiment, based on the operation of the user, for example, a specific game medium not desired by the user is selected from the lottery list before drawing the gacha, and the game medium deleting means 235 deletes the specific game medium. As a result, the population parameter of the game medium in the lottery list is reduced from that before the deletion. Therefore, as a result, the probability that the desired game medium can be obtained by the gacha increases, and the fun of the gacha is improved.

Further, when the game medium is deleted from the lottery list, the price calculation means 234 calculates the price required for deleting the game medium. Since the price is determined by the type and number of game media, or the number of times the deletion disposal is executed by the game media deletion means 235, the user selects the game media to be deleted from the lottery list in consideration of the price. Can be done. Therefore, the user can enjoy the fun of gacha while adjusting the billing amount.

Further, the game medium deletion means 235 compensates for a specific parameter other than charging, specifically, a game medium specialized for the purpose of deleting the game medium and its number, points acquired at the progress of the game, and the like. In addition, the game medium can be deleted. Therefore, the user can remove the game medium from the lottery list by a method other than billing. Therefore, it is possible to suppress an excessive charge amount borne by the user.

[Second Embodiment]
In the present embodiment, the case where the gacha is not a "box gacha" but a normal gacha drawn according to a certain probability set in each game medium will be described.

In the server device 2 according to the present embodiment, the changing means 237 is added to the control unit 23 of the server device 2 according to the first embodiment. Other than this difference, for example, the configuration of the game device 5 is the same as that of the first embodiment.

<Functional configuration of the control unit 23 of the server device 2>
By executing various programs, the control unit 23 functions as information processing means 231, collation means 232, game medium lottery means 233, price calculation means 234, game medium deletion means 235, distribution means 236, and change means 237. (Fig. 8).

The changing means 237 is changed so as to increase the lottery probability preset for each game medium after the processing of deleting the specific game medium by the game medium deleting means 235. That is, the changing means 237 increases the lottery probability of the game medium remaining in the lottery list after the deletion of the specific game medium.

The information processing means 231, the collation means 232, the game medium lottery means 233, the price calculation means 234, the game medium deletion means 235, and the distribution means 236 are the same as those in the first embodiment.

<About the flow of processing performed by the server device 2 and the game device 5>
The flow of processing performed by the server device 2 and the game device 5 described above will be described with reference to FIG.

The server device 2 and the game device 5 perform the same processing as the steps # 1 to # 13 and # 16 to # 21 in FIG. 2 of the first embodiment. That is, # 1 to # 13 in FIG. 9 correspond to # 1 to # 13 in FIG. 2, and # 17 to # 22 in FIG. 9 correspond to # 16 to # 21 in FIG. In the following, the description will be centered on # 14 to # 16 in FIG.

After the game medium deleting means 235 deletes the specific game medium (# 13), the changing means 237 changes the lottery probability of each game medium in the lottery list (# 14).

For example, suppose that there are four types of game media A, B, C, and D in the lottery list, and the lottery probabilities are 15%, 25%, 25%, and 35%, respectively (100% in total). Then, it is assumed that the game medium D is selected as the specific game medium by the user's operation, and the game medium deleting means 235 deletes the game medium D. At this time, since the game medium D having the lottery probability of 35% was deleted, the changing means 237 compares the lottery probabilities of the game media A, B, and C remaining in the lottery list with each other before the deletion of the game medium D. It is increased to 23%, 38.5% and 38.5% (100% in total).
