Description

This disclosure relates to an information processing device, a program, and a content provision method.

Conventional social games are provided with a lottery function that awards a card as an object to the user through a lottery. Conventional social games are also provided with a lottery function (a lottery that allows redraws) that allows the user to redraw (i.e., redraw). A lottery that allows redraws means that if the user does not like the card determined by the lottery, they can redraw the card without receiving it (see, for example, Patent Document 1).

JP 2014-180334 A

However, with the technology of Patent Document 1, if a new lottery is held without receiving the cards already drawn, all cards drawn in the previous lottery are subject to redraw, and the cards drawn in the previous lottery cannot be collected later. Therefore, the lottery function that allows the user to redraw the lottery has the problem that it may not increase the user's satisfaction with the lottery results.

The objective of this disclosure is to provide a new mechanism for increasing user satisfaction with the results of a lottery in which in-game content is the subject of the lottery.

According to one aspect of the present disclosure, an information processing device is provided that has a first lottery unit that conducts a first lottery in which in-game content is the subject of a lottery and selects a plurality of contents from the content that is the subject of the lottery; an exchange condition presentation unit that accepts a first selection of the content that the user wishes to exchange from the plurality of contents selected by the first lottery and presents to the user exchange conditions based on information accompanying the content that is the subject of the exchange; a second lottery unit that accepts a second selection, by which the user can add the content that he or she wishes to exchange from the plurality of contents selected by the first lottery, and conducts a second lottery to exchange the content that is the subject of the exchange in accordance with the exchange conditions satisfied by the content that is the subject of the exchange selected by the first selection and the second selection; and a content granting unit that grants the content to the user based on the results of the first lottery and the second lottery, wherein the information accompanying the content is the rarity of the content that is granted as information to the content, and the exchange conditions include conditions necessary for exchanging the content for a rarity different from the rarity that can be exchanged for the selected exchange object .

According to one aspect, a new mechanism can be provided that increases user satisfaction with the results of a lottery in which in-game content is the subject of the lottery.

Note that in this embodiment, an example of a lottery function in which in-game content such as in-game characters, weapons, equipment, items, and cards are the subject of a lottery is described, but is not limited to in-game content. The lottery function in this embodiment is an example of information processing in which multiple pieces of content to be granted to a user are selected by lottery from the content that is the subject of the lottery.

[Game System]
First, a game system 10 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the game system 10 according to the present embodiment. The game system 10 according to an embodiment has a configuration in which a client 20 and a server 30 are communicatively connected via a network 40.

The client 20 is an example of an information processing terminal on which a user plays a game. The client 20 may be a portable game console, a personal computer, a tablet terminal, a mobile phone such as a smartphone, a home game device, an arcade game device, etc. The client 20 accepts operations from the user via an input device such as a touch panel, a controller, a mouse, a keyboard, etc., and displays an image corresponding to the operation on a display device to allow the user to play the game. The number of clients 20 is not limited to three, and may be other than three.

The server 30 is an example of an information processing device that provides the client 20 with functions necessary for the game by transmitting and receiving data between the server 30 and the client 20. The server 30 may be realized by a cloud computer. The number of servers 30 shown in FIG. 1 is not limited to one, and there may be two or more servers for distributed processing. For example, the server 30 is used for downloading game programs (applications) to the client 20, user login processing, processing related to a lottery function in which in-game content is the subject of a lottery, and management of various tables.

Communication device 133 is a communication device such as a network card that controls communication.

Figure 4 is a diagram showing an example of the functional configuration of the client 20. The client 20 has a memory unit 21, a client control unit 22, an operation reception unit 23, an output control unit 24, and a client-side communication unit 25. The memory unit 21 stores programs such as a game program 31, data used by the programs, and the like. The memory unit 21 may be realized by a storage device 122, or may be realized by a storage device connected via a network 40.

The client control unit 22 performs overall control of the client 20. Overall control of the client 20 includes control of the game played by the user in general. The client control unit 22 is realized by the CPU 121 executing the processing described in the game program 31. The client control unit 22 has a game control unit 35, an image generation unit 36, a request transmission unit 37, and a result reception unit 38.

The game control unit 35 controls the game played by the user. The image generation unit 36 generates images necessary for displaying the game screen, such as the image of the lottery result screen described below. The request transmission unit 37 makes requests for various processes to the server 30 based on user operations, such as requesting the server 30 to perform lottery processing in which content within the game is the subject of a lottery. The result receiving unit 38 receives the results of requests for various processes, such as the lottery results in response to a lottery processing request made to the server 30.

The operation reception unit 23 receives various operations by the user on the input device 124. The output control unit 24 outputs a game screen and game sounds to the display device 125. The operation reception unit 23 is realized by the CPU 121 controlling the input device 124. The output control unit 24 is realized by the CPU 121 controlling the display device 125.

Here, various operations by the user on the input device 124 refer to operations by the user playing the game operating the operation acceptance unit 23 in order to cause the CPU 121 to execute processing. The operation acceptance unit 23 accepts various operations from the user playing the game. The client control unit 22 progresses the game based on the various operations accepted by the operation acceptance unit 23 from the user.

The output control unit 24 outputs game screens and game sounds to the display device 125 based on the image data and sound data generated by the client control unit 22. The client-side communication unit 25 communicates with the server 30. Note that the client-side communication unit 25 is realized by the CPU 121 executing the game program 31 and controlling the communication device 123 in accordance with the game program 31.

Figure 5 is a diagram showing an example of the functional configuration of the server 30. The server 30 in Figure 5 has a storage unit 51, a server control unit 52, and a server-side communication unit 53.

The memory unit 51 stores a server program 61, a game program 62, data used by various programs, a user information table 63, a content information table 64, an exchange condition table 65, and a lottery probability table 66. The memory unit 51 may be realized by the memory device 132, or may be realized by a memory device connected via the network 40.

In the user information table 63, information about users who play games on the client 20 is set. The user information table 63 manages user information that associates users who play games on the client 20 with in-game content owned by each user.

The content information table 64 manages information related to the content within the game that is the subject of the lottery. The information related to the content includes various information necessary for using the content within the game, such as the rarity of the content within the game that is the subject of the lottery, the content name, abilities, attributes, and images. The rarity of the content is an example of information associated with the content, and indicates the rarity, strength, excellence, etc. of the content within the game. In this embodiment, the information associated with the content may be information that classifies the value of the content within the game based on some index.

The exchange condition table 65 manages the exchange conditions used in the re-drawing described below. Figure 6 is a configuration diagram of an example of the exchange condition table 65 used in this embodiment. The exchange condition table 65 in Figure 6 manages information on exchange conditions having items such as exchange condition ID, exchange target, and grant target. The item "exchange condition ID" is an example of identification information that identifies the exchange conditions.

The "Granted item" item is information indicating the rarity and quantity of the in-game content that will be awarded and won in the re-draw lottery described below. The "Exchange item" item is information indicating the rarity and quantity of the in-game content that will be exchanged and consumed to obtain the in-game content indicated in the "Granted item" item.

For example, the exchange condition with exchange condition ID "T1" is an example of exchange condition information for allowing a user to win in-game content with a rarity and quantity of "SR x 9" by conducting a re-draw for in-game content with a rarity and quantity of "SSR x 1". Also, the exchange condition with exchange condition ID "T2" is an example of exchange condition information for allowing a user to win in-game content with a rarity and quantity of "SSR x 1" by conducting a re-draw for in-game content with a rarity and quantity of "SR x 9".

According to the exchange conditions of exchange condition ID "T1", a user can obtain nine in-game contents with a rarity of "SR" by selecting one in-game content with a rarity of "SSR" as the exchange target and executing a re-draw. Also, according to the exchange conditions of exchange condition ID "T2", a user can obtain one in-game content with a rarity of "SSR" by selecting nine in-game contents with a rarity of "SR" as the exchange target and executing a re-draw.

In this way, the exchange condition table 65 in FIG. 6 manages the exchange conditions so that when the rarity of the content to be exchanged is higher than the rarity of the content to be given, the number of pieces of content to be given is greater than the number of pieces of content to be exchanged. Also, the exchange condition table 65 in FIG. 6 manages the exchange conditions so that when the rarity of the content to be exchanged is lower than the rarity of the content to be given, the number of pieces of content to be given is less than the number of pieces of content to be exchanged.

The lottery probability table 66 manages the lottery probability of the in-game content used by the lottery function. FIG. 7 is a configuration diagram of an example of the lottery probability table 66 used in this embodiment. The lottery probability table 66 in FIG. 7 manages lottery probability information having items of rarity, content name, and drop probability. The item "Rarity" is information indicating the rarity of the in-game content. The item "Content name" is information indicating the name of the in-game content. The item "Drop probability" is information indicating the drop probability in the lottery function of the in-game content specified by the items "Rarity" and "Content name".

The lottery probability table 66 used in the re-draw in this embodiment is the lottery probability table 66 in FIG. 7 modified according to the contents of the exchange condition table 65 in FIG. 6, as described below.

The server control unit 52 performs overall control of the server 30. The server control unit 52 is realized by the CPU 131 executing the processes described in the server program 61. For example, the server control unit 52 performs a download process that downloads the game program 62 stored in the storage unit 51, data used by the game program 62, and the like, to the client 20.

The server control unit 52 has a first lottery unit 71, an exchange condition presentation unit 72, a second lottery unit 73, a lottery result presentation unit 74, a content provision unit 75, a request receiving unit 76, and a result sending unit 77.

The first lottery unit 71 performs lottery processing for the in-game content to be selected in accordance with a lottery request from the client 20, and responds to the client 20 with information on the content selected as a result of the lottery. Note that lottery requests from the client 20 include single lottery requests that request a single lottery process, and continuous lottery requests that request multiple lottery processes. The process related to re-selection according to this embodiment is executed when a continuous lottery request that requests multiple lottery processes is received from the client 20, as described below.

When the user selects content to be exchanged from among the multiple in-game contents displayed on the client 20 as a result of the lottery by the first lottery unit 71, the exchange condition presentation unit 72 presents the exchange conditions for the re-lottery to the user. The exchange conditions for the re-lottery are information that present the user with the relationship between the content to be exchanged and the content to be granted. By checking the presented exchange conditions, the user can understand the conditions of the content to be exchanged that are necessary to obtain the desired rarity and number of in-game content through a re-lottery.

The second lottery unit 73 can accept a selection of additional content to be exchanged from among the multiple in-game contents displayed on the client 20 as a result of the lottery by the first lottery unit 71. The second lottery unit 73 re-selects the content to be given to be exchanged for the content to be exchanged, in accordance with the exchange conditions satisfied by the content selected as the exchange target.

The lottery result presentation unit 74 displays the result of the lottery by the first lottery unit 71 and the result of the lottery by the second lottery unit 73 on the client 20 to present the result of the lottery to the user. The lottery result screen displayed by the lottery result presentation unit 74 (described later) first displays the result of the lottery by the first lottery unit 71, and the display content is updated with the result of the lottery by the second lottery unit 73 each time a lottery is performed by the second lottery unit 73.

When the content provision unit 75 receives a request from the user to confirm the lottery result, it provides the user with the in-game content by reflecting the lottery result in the user information table 63.

The request receiving unit 76 receives various processing requests sent from the client 20 based on user operations. The result sending unit 77 performs various processing in response to the requests received from the client 20 and sends the results of the processing to the client 20.

Furthermore, the server-side communication unit 53 communicates with the client 20. The server-side communication unit 53 is realized by the CPU 131 executing the server program 61 and controlling the communication device 133 in accordance with the server program 61.

The functional configuration of the client 20 shown in FIG. 4 and the functional configuration of the server 30 shown in FIG. 5 are merely examples, and for example, at least one of the functional configurations of the server 30 shown in FIG. 5 may be included in the functional configuration of the client 20 shown in FIG. 4. In other words, it is sufficient that either the client 20 or the server 30 has the functional configurations shown in FIG. 4 and FIG. 5.

[Game Actions]
In the following, a process will be described that takes place after a continuous lottery operation is received from a user, such as a pressing operation on the continuous lottery button on the lottery screen.

Figure 8 is a flowchart of an example of processing related to the lottery function according to this embodiment. In step S10, the first lottery unit 71 of the server 30 accepts a request for continuous lotteries from the client 20 operated by the user. In step S12, the first lottery unit 71 executes the lottery process for the in-game content to be lottery-selected a predetermined number of times in succession, such as 10 times.

In the continuous lottery in step S12, a lottery process is performed to select multiple contents by lottery from the contents in the game that are the subject of the lottery, for example based on the drop probability in the lottery probability table 66 in FIG. 7. The first lottery unit 71 responds to the client 20 with information on the contents selected as a result of the continuous lottery.

In step S14, the lottery result presentation unit 74 of the server 30 causes the client 20 to display a lottery result screen 1000, for example, as shown in FIG. 9. FIG. 9 is an image diagram of an example of the lottery result screen 1000.

The lottery result screen 1000 in FIG. 9 includes a display field 1002 for the in-game content selected as a result of the continuous lottery, and a Confirm button 1006. By pressing the Confirm button 1006, the user can request that the lottery result be confirmed with the in-game content displayed in the display field 1002. In the processing of the flowchart in FIG. 8, after step S14, the process proceeds from step S16 to step S32, where it is determined that an instruction to end the lottery has been given, and processing is executed to confirm the lottery result, and the process ends.

Furthermore, a user who wishes to redraw performs an operation to select the content to be exchanged, such as by tapping the content to be redrawn from among the in-game content displayed in the display field 1002. The operation of the user who selected the content to be exchanged from the display field 1002 is notified to the exchange condition presentation unit 72 of the server 30.

If it is determined in step S16 that a content to be exchanged has been selected, the exchange condition presentation unit 72 of the server 30 reads the exchange conditions of the content selected as the content to be exchanged from the exchange condition table 65 in step S18.

For example, in the case of the exchange condition table 65 in FIG. 6, if the rarity of the content to be exchanged is "R", the exchange condition presentation unit 72 reads out the exchange conditions with exchange condition IDs "T4" and "T5", which have in-game content of rarity "R" set as the exchange target, from the exchange condition table 65. If the rarity of the content to be exchanged is "SR", the exchange condition presentation unit 72 reads out the exchange conditions with exchange condition IDs "T2" and "T3", which have in-game content of rarity "SR" set as the exchange target, from the exchange condition table 65.

The exchange condition presentation unit 72 responds to the client 20 with the exchange condition information read from the exchange condition table 65. The lottery result presentation unit 74 causes the client 20 to display a lottery result screen 1000, for example, as shown in FIG. 10. FIG. 10 is an image diagram of an example of the lottery result screen 1000 after the content to be exchanged has been selected.

The lottery result screen 1000 in FIG. 10 displays a check mark 1010 on the content selected by the user as the item to be exchanged, clearly displaying the content currently selected as the item to be exchanged. After the user has selected the content to be exchanged, the lottery result screen 1000 in FIG. 10 also displays a re-draw button 1004 for receiving an operation from the user to request a re-draw. By pressing the re-draw button 1004, the user can request a re-draw for the content currently selected as the item to be exchanged.

In addition, the lottery result screen 1000 in FIG. 10 displays exchange condition information 1012 read from the exchange condition table 65. By checking the exchange condition information 1012 displayed on the lottery result screen 1000, the user can understand the rarity and number of the content that will be won if a re-lottery is performed as is, and the rarity and number of the exchange target content that needs to be added in order to win content of higher rarity than the exchange target.

The user can refer to the exchange condition information 1012 displayed on the lottery result screen 1000 in FIG. 10 to decide whether to continue with the lottery again or to add the content to be exchanged and then re-draw the lottery.

Here, we will first explain the case where a re-draw is performed after the user adds content to be exchanged. On the drawing result screen 1000 in FIG. 10, the user performs an operation to select the content that he or she wishes to add as an exchange target from the in-game content displayed in the display field 1002.

In the process of the flowchart in FIG. 8, after step S18, it is determined that an additional selection of content to be exchanged has been made before the user requests a re-draw, and the process proceeds to step S22. The operation of the user who has selected additional content to be exchanged from the display field 1002 is notified to the exchange condition presentation unit 72 of the server 30.

When it is determined that additional content to be exchanged has been selected, the exchange condition presentation unit 72 of the server 30 reads the exchange conditions for the selected content, including the additional content selected as the content to be exchanged, from the exchange condition table 65.

The exchange condition presentation unit 72 responds to the client 20 with the information on the exchange conditions read from the exchange condition table 65. The lottery result presentation unit 74 updates the lottery result screen 1000 displayed on the client 20, for example, as shown in FIG. 11. FIG. 11 is an image diagram of an example of the lottery result screen 1000 after additional content to be exchanged has been selected.

The lottery result screen 1000 in FIG. 11 displays a check mark 1010 on the content currently selected as an exchange target, including any additional content selected by the user as an exchange target. In addition, the exchange condition information 1012 displayed on the lottery result screen 1000 in FIG. 11 has been updated due to the addition of content as an exchange target.

For example, in the example of the lottery result screen 1000 in FIG. 11, "4" pieces of content with rarity "R" have been selected as the exchange item, so the exchange condition ID "T4" is met, which increases the rarity of the item to be granted compared to the item to be exchanged.

As a result, the exchange condition information 1012 on the lottery result screen 1000 in Figure 11 has been updated to "Four R contents have been selected. If the lottery is re-drawn as is, the SR content will be confirmed as a winning entry." in accordance with the content of the fulfilled exchange condition ID "T4".

By checking the exchange condition information 1012 displayed on the lottery result screen 1000 in FIG. 11, the user can understand that if they run the lottery again, they will be able to win content that is rarer than the item that was exchanged.

By pressing the redraw button 1004 on the lottery result screen 1000 in FIG. 11, the user can request a redraw for the content displayed in the display field 1002 with a check mark 1010 placed on it as the selected exchange item. The request for a redraw specifying the content to be exchanged is notified to the second lottery unit 73 of the server 30.

In step S24, the second selection unit 73 determines whether the content to be exchanged specified in the request for reselection satisfies an exchange condition that increases the rarity of the granted content to a higher level than the content to be exchanged.

In the example of the lottery result screen 1000 in FIG. 11, four pieces of content with rarity "R" have been selected as the exchange item, so the exchange condition ID "T4" is met, which increases the rarity of the item to be granted compared to the item to be exchanged.

Therefore, the second selection unit 73 proceeds from step S24 to step S26, and performs a reselection to select the content to be exchanged for the content to be exchanged, according to the exchange condition that makes the content to be exchanged more rare than the content to be exchanged. Note that the selection probability table 66 used in the reselection in step S26 is modified according to the content of the exchange condition that was determined to be satisfied in step S24.

For example, in the example of lottery result screen 1000 in FIG. 11, the rarity of the content re-drawn from the contents of the grant target of exchange condition ID "T4" is fixed to "SR", so the contents of lottery probability table 66 in FIG. 7 are updated to the lottery probability table 66 in FIG. 12. By using the lottery probability table 66 in FIG. 12, the rarity of the content re-drawn in step S26 is fixed to "SR".

The second lottery unit 73 responds to the client 20 with information on the content selected as a result of the re-lottery. In step S30, the lottery result presentation unit 74 of the server 30 causes the client 20 to display a lottery result screen 1000, for example, as shown in FIG. 13. FIG. 13 is an image diagram of an example of the lottery result screen 1000 on which the result of the re-lottery is displayed.

In the lottery result screen 1000 of FIG. 13, the four contents selected as contents to be exchanged in the lottery result screen 1000 of FIG. 11 are removed from the display area 1002, and the content of rarity "SR" that was won by the re-lottery is additionally displayed. Note that the user can also select the contents to be exchanged on the lottery result screen 1000 of FIG. 13, in which the multiple contents in the lottery result screen 1000 of FIG. 9, which are the results of successive lotteries, have been updated according to the results of the re-lottery.

Furthermore, a user who wishes to re-draw the lottery can repeat steps S16 to S32 by selecting the content to be exchanged from the contents displayed in display field 1002 of FIG. 13. The user can request to confirm the result of the lottery with the content displayed in display field 1002 of FIG. 13 by pressing confirm button 1006 of FIG. 13.

In step S24, if the content to be exchanged specified in the request for re-drawing does not satisfy the exchange condition that increases the rarity of the granted item more than the content to be exchanged, the second lottery unit 73 proceeds to processing of step S28. In step S20, if no additional content to be exchanged is selected, the second lottery unit 73 proceeds to processing of step S28.

In the example of the lottery result screen 1000 in Figure 10, "1" content of rarity "R" has been selected as the exchange item, so exchange condition ID "T4" which increases the rarity of the grant item compared to the exchange item is not met, but exchange condition ID "T5" which decreases the rarity of the grant item compared to the exchange item is met.

Therefore, in the process of step S28, the second selection unit 73 performs a re-selection of the grant target content to be exchanged for the exchange target content, according to the exchange conditions that make the grant target have a lower rarity than the exchange target. Note that since the process of step S28 is a re-selection that makes the grant target have a lower rarity than the exchange target, the number of grant target contents won in the re-selection will be greater than the number of exchange target contents.

The lottery probability table 66 used in the re-draw in step S28 is the lottery probability table 66 in FIG. 7 modified according to exchange conditions that make the rarity of the grant target lower than that of the exchange target.

For example, in the example of lottery result screen 1000 in FIG. 10, the rarity of the content re-drawn from the contents of the grant target of exchange condition ID "T5" is fixed to "N", so the contents of lottery probability table 66 in FIG. 7 are updated to the lottery probability table 66 in FIG. 15 (C). By using the lottery probability table 66 in FIG. 15 (C), the rarity of the content re-drawn in step S28 is fixed to "N".

When the selection probability table 66 in FIG. 15(A) is used, the rarity of the content reselected in step S28 is fixed to "SSR." When the selection probability table 66 in FIG. 15(B) is used, the rarity of the content reselected in step S28 is fixed to "R."

The second lottery unit 73 responds to the client 20 with information on the content selected as a result of the re-lottery. In step S30, the lottery result presentation unit 74 of the server 30 causes the client 20 to display a lottery result screen 1000, for example, as shown in FIG. 14. FIG. 14 is an image diagram of an example of the lottery result screen 1000 on which the result of the re-lottery is displayed.

In the lottery result screen 1000 of FIG. 14, one piece of content selected as the content to be exchanged in the lottery result screen 1000 of FIG. 10 is removed from the display area 1002, and a piece of content of rarity "N" that was won by re-drawing is additionally displayed. Note that the user can also select the content to be exchanged on the lottery result screen 1000 of FIG. 14, where the multiple pieces of content in the lottery result screen 1000 of FIG. 9, which are the results of successive draws, have been updated according to the results of the re-drawing.

Furthermore, a user who wishes to re-draw the lottery can repeat steps S16 to S32 by selecting the content to be exchanged from the contents displayed in display field 1002 of FIG. 14. The user can request to confirm the result of the lottery with the content displayed in display field 1002 of FIG. 14 by pressing confirm button 1006 of FIG. 14.

As described above, this embodiment can provide a new mechanism for increasing user satisfaction with the results of a lottery in which in-game content is the subject of the lottery.
