It is done.

<About game media deletion processing>
The game media deletion processing and lottery processing performed mainly by the game content lottery means 233, the price calculation means 234, and the game content deletion means 235 will be described in detail.

  In the same way as in the real world gacha, the gacha that appears while the game is in progress draws the game media sequentially from the lottery list containing a certain number of game media, and finally the game media in the lottery list There is a system called “Box Gacha” that will acquire all of the above.

  However, as described above, when a gacha is drawn by billing, the billing amount may be high as a result of repeating billing until a desired game medium is acquired. Further, if it is possible to easily obtain a desired game medium by charging, there is a possibility that the interest of gacha may be lost.

  Therefore, the game medium deleting unit 235 according to the present embodiment performs a process of deleting a game medium that the user does not want to acquire from the lottery list in advance before drawing the gacha. In particular, in the present embodiment, a game content deletion process and a lottery process in the box gacha will be described.

  FIG. 3 is an example of an image displayed on the display 61 when the lottery event occurs while the game is in progress. On the display 61, a lottery image a by gacha is displayed. The lottery image a includes items a2, a2,... A2, which are a plurality of game media displayed so that individual contents are not specified, a case a1 in which items a2, a2,.

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

  When a game medium that the user desires to delete is selected from the touch pad 63 by the user's operation, and an input is made to pay the price for the deletion of the game medium, the game medium deleting means 235 of the server device 2 is selected. The deleted game medium (corresponding to a specific game medium) is deleted from the lottery list. Thereafter, the lottery list after the deletion process is transmitted to the game apparatus 5.

  FIG. 5 shows a lottery image a displayed on the display 61 after the specific game medium is deleted from the lottery list. The lottery image a indicates that the number of game media in the lottery list has decreased by the number of specific game media deleted from the lottery list, based on the items a2, a2,. Show.

On the other hand, when the “draw gacha” button a4 is selected from the touch pad 63 by the user's operation on the screen of FIG. 3, the lottery list stored in the storage unit 22 by the game medium lottery means 233, that is, the deletion process is performed. Arbitrary game media are drawn from a lottery list that is not. The lottery game media are 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 unit 565 causes the display 61 and the speaker 62 to notify the transmitted game media.

<Flow of processing performed by server device 2 and 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.

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

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

  For example, as shown in FIG. 3, the game apparatus 5 that has received the information displays a 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 unit 563 generates a deletion request to delete the game medium, via the communication unit 561. To the server device 2 (# 5).

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

  Further, the price calculation means 234 transmits the calculated price information to the game apparatus 5 via the distribution means 236 (# 8). The game apparatus 5 that has received the price information (# 9) 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 necessary for the deletion is displayed for each game media (item). . In FIG. 4, a billing amount a6, a game medium (item) a7, and a point a8 are displayed.

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

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

Further, the game medium deleting unit 235 transmits the lottery list update information stored in the storage unit 22 after the game medium deleting process described above to the game apparatus 5 via the distribution unit 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 apparatus 5 that has received the update information continues to display a lottery gacha image on the display 61 (# 15). Since the specific game medium is 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 is deleted. Is displayed.

It is assumed that the user inputs the “delete item” button a5 via the touch pad 63 of the game apparatus 5 (YES in # 16). Then, the instruction acquisition unit 563 sends a game medium deletion request to the server device 2 via the communication unit 561 (# 5). Thereafter, # 6 and subsequent steps are repeated in the same manner as described above, but the price calculation means 234 again calculates the price required for the deletion process for the game media in the lottery list, and as shown in FIG. Is displayed on the display 61. FIG. 6 shows a selection screen for the second price payment after “item A” is deleted for the first time in FIG.

  On the other hand, it is assumed that the user inputs the “Draw Gacha” button a4 via the touch pad 63 of the game apparatus 5 (NO in # 16). Then, the instruction acquisition unit 563 generates a game media download request, and the communication unit 561 transmits it to the server device 2 (# 17).

  Similarly, in step # 4, when the “Do not delete game media”, that is, “Draw gacha” button a4 is selected by the user's operation (NO in step # 4), the instruction acquisition unit 563 displays the game media. A download request is generated, and the communication means 561 transmits it 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 deletion process of the specific game medium is performed, the lottery is performed from the lottery list after the deletion. If the specific game medium is not deleted, a lottery is performed from a lottery list that has not been deleted.

  When a lottery is performed by the game media lottery means 233, the game media deletion means 235 performs a deletion process of the game media 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 apparatus 5 (# 19), and the game medium is stored in the storage unit 55 of the game apparatus 5. The notifying unit 565 notifies the game medium to the display 61 and / or the speaker 62 as shown in FIG. 7 (# 20).
