Description

[Technical field]

[0001] The present invention relates to an information processing device and a program. [Background technology]

[0002] A program is known for causing a computer to execute a synthesis game in which a user possesses a character as an example of content, and a character is synthesized using multiple characters (material characters) that serve as material for the characters possessed by the user (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5526294 Summary of the Invention [Problem to be solved by the invention]

[0004] If a user does not have all of the material characters required for character synthesis, the user must acquire the missing material characters. However, there are cases where the user forgets which of the material characters required for character synthesis are missing. In this case, the user must again compare the characters he or she owns with the material characters required for character synthesis, and check in detail which material characters are missing.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to enable a user to easily check required material content. [Means for solving the problem]

[0006] The main invention of the present invention to solve the above problems is: a content information storage unit that stores content information in which a plurality of material contents required for synthesis of a synthesis source content are set; a user information storage unit that stores user information in which one or more contents owned by a user are set; a reservation registration section which, in response to a user's operation of designating a content to be used as a synthesis source from among the contents owned by the user, refers to the content information and the user information, and pre-registers, as a desired acquisition target, a missing content that the user does not own, among a plurality of material contents required for synthesis of the designated content to be used as the synthesis source; a notification unit that, in response to a user's operation, notifies the user of a possession status regarding content that has been registered in advance as a desired acquisition target; The present invention relates to an information processing device comprising: According to such an information processing device, the user can specify the content to be synthesized, and the missing material content can be registered in advance as a desired acquisition target. Furthermore, the possession status of the registered content can be easily grasped. This makes it possible for the user to easily check the material content required.

[0007] and an assigning unit that assigns one or more contents selected from the plurality of contents to a user and allows the user to possess the selected one or more contents, It is preferable that, when the granting unit grants content matching any of the contents previously registered as items desired to be acquired, the reservation registration unit excludes the matching content from items desired to be acquired. In this way, by providing the missing material content, the number of pre-registered desired acquisition items decreases, making it possible to properly grasp the material content required by the user.

[0008] In addition, it is preferable that the notification unit notifies the user that it is possible to synthesize the source content specified by the user since all contents previously registered as items desired to be acquired have been removed from the items desired to be acquired. This allows the user, upon receiving this notification, to immediately start compositing the source content that he or she has specified.

[0009] In addition, the content information includes a game type in which each of the plurality of material contents can be acquired in association with the material contents, and It is preferable that the notification unit notifies the player of the game type of the content that has been registered in advance as an object to be acquired at a predetermined timing. This allows users to be notified at the appropriate time of the game type in which they can obtain missing material content, even if they do not know it. This makes it easy for users to obtain the material content they need.

[0010] In addition, the content information includes destination contents corresponding to the source contents, and the reservation registration unit, in response to a user's operation of designating a content to be a synthesis source from among the contents owned by the user, refers to the content information and the user information; Among a plurality of material contents required for synthesis of the original content designated by the user, a content that is not possessed by the user is registered in advance as an object to be acquired; It is desirable for the user to register in advance, as an item to be acquired, the missing content that the user does not possess, among other source contents to which the missing content corresponds as the destination content, and among the material contents required for synthesizing the other source contents. Thus, even if the synthesis must be performed in stages because the missing material contents are also the contents to be synthesized, the missing contents among the contents required for synthesis at each stage can be registered as the acquisition target all at once.

[0011] Furthermore, in response to a user's operation of designating a plurality of original contents from among the contents owned by the user, the reservation registration unit refers to the content information and the user information, and for each of the designated original contents, registers missing contents among a plurality of material contents required for composition as desired acquisition targets; It is preferable that the notification section notifies the user of the possession status of all the contents registered as the acquisition target collectively in response to the user's operation. This allows the user to register the missing contents among the contents required for each synthesis as a desired acquisition target all at once, even if the user specifies multiple contents to be synthesized. Furthermore, the possession status of the pre-registered contents can be grasped all at once.

[0057] The synthesis game in this embodiment is a game in which, when a user inputs an operation to execute character synthesis, the player combines a character to be synthesized (base character) with a character to be used as a synthesis material (material character) to strengthen the abilities of the base character (strengthening synthesis) or to grow the base character to the next stage and evolve it into a character to be synthesized (evolved character) (evolutionary synthesis).

[0058] A user selects a base character and a material character from among the characters he or she owns, and performs strengthening synthesis or evolution synthesis. In strengthening synthesis, the material character is lost from the user's possession, but in exchange, the ability value of the base character that the user continues to own can be improved or new skills can be added. In evolution synthesis, by synthesizing all material characters that are pre-associated with a base character with that base character, the user loses all material characters from the user's possession, but in exchange, the user can possess an evolved character that has been developed from the base character.

[0059] In this embodiment, the user can also sell his / her own character. In exchange for losing the sold character from the user's possession, the user can obtain points.

[0060] <Operation> 《Reservation Registration》 FIG. 5 is a flowchart illustrating an example of an operation related to reservation registration in the information processing system 1 according to this embodiment.

[0069] Returning to Fig. 5, the display control unit 204 then controls the display of a character selection screen displaying a list of characters owned by the user on the screen display unit 160 of the client terminal 10. At this time, in the list of owned characters, characters that can evolve are displayed in a manner that allows them to be distinguished from characters that cannot evolve, and display control is performed so that the user can select only characters that can evolve.

[0070] Next, when the character selection screen is displayed on the screen display unit 160 of the client terminal 10, the user performs an operation to designate one of the base characters on the client terminal 10. When the user performs an operation to designate one of the base characters, the operation acceptance unit 150 of the client terminal 10 accepts the operation content based on the user's designation of the base character (step S12).

[0071] The request sending unit 101 of the client terminal 10 then makes a request to the server device 20 based on the operation content accepted from the user by the operation accepting unit 150. When the game progression unit 201 of the server device 20 accepts the operation content from the client terminal 10, it requests the reservation registration unit 205 to execute reservation registration processing for the base character specified by the user.

[0072] Next, when the reservation registration unit 205 of the server device 20 receives a request from the game progression unit 201 to execute the reservation registration process, it refers to the character information stored in the character information storage unit 221 and obtains the evolved character to be used as the synthesis target that is associated with the base character specified by the user (step S13).

[0073] Next, the reservation registration unit 205 of the server device 20 refers to the character information stored in the character information storage unit 221 and acquires multiple material characters (i.e., material characters required for evolutionary synthesis of the base character) associated with the base character specified by the user (step S14).

[0074] Next, the reservation registration unit 205 of the server device 20 refers to the owned characters set in the user information stored in the user information storage unit 222, and identifies the missing characters that the user does not yet possess from among the multiple material characters obtained in the processing of step S14 described above (step S15).

[0075] Next, the reservation registration unit 205 of the server device 20 refers to the character information stored in the character information storage unit 221 and determines whether there are other base characters that correspond to the missing characters identified in the processing of step S15 described above as evolved characters to be synthesized with (step S16).

[0076] If it is determined that there is no other base character to which the missing character corresponds as an evolved character, the process proceeds to step S19 (described later). On the other hand, if it is determined that there is another base character to which the missing material character corresponds as an evolved character, the process proceeds to step S17 (described later).

[0077] Next, if the reservation registration unit 205 of the server device 20 determines that there are other base characters to which the missing material characters are associated as evolved characters, it refers to the character information stored in the character information storage unit 221 and obtains multiple material characters (i.e., material characters required for the evolutionary synthesis of other base characters) that are associated with the other base characters (step S17).

[0078] Next, the reservation registration unit 205 of the server device 20 refers to the owned characters set in the user information stored in the user information storage unit 222, and identifies the missing characters that the user does not yet possess from among the other base characters and the multiple material characters obtained in the processing of step S17 (step S18).

[0079] Next, when the reservation registration unit 205 of the server device 20 acquires data regarding the character required for the evolutionary synthesis of the base character specified by the user in this manner, it requests the display control unit 204 to execute screen display control so as to display a reservation registration screen on the client terminal 10 (step S19).

[0080] When the display control unit 204 is requested by the reservation registration unit 205 to execute screen display control, if the determination in the process of the above-mentioned step S16 is negative, the display control unit 204 controls the screen display unit 160 of the client terminal 10 to display a reservation registration screen as shown in Fig. 10. On the other hand, if the determination in the process of the above-mentioned step S16 is positive, the display control unit 204 controls the screen display unit 160 of the client terminal 10 to display a reservation registration screen as shown in Fig. 11.

[0081] Fig. 10 is an image diagram showing an example of a reservation registration screen. The reservation registration screen 500 shown in Fig. 10 displays an evolved character display area 501, a base character display area 502, a material character display area 503, a missing character display area 504, an operation button 505 for performing reservation registration, and an operation button 506 for reselecting a character.

[0082] The evolved character acquired in the process of step S13 described above is displayed in the evolved character display area 501. Here, "Character S" is displayed as the evolved character.

[0083] The base character display area 502 displays the base character designated by the user in the process of step S12 described above. Here, "Character A" is displayed as the base character. In other words, when evolution synthesis is performed on the synthesis source "Character A", it will evolve into the synthesis destination "Character S".

[0084] In material character display area 503, multiple material characters acquired in the processing of step S14 described above are displayed. Here, "Character X", "Character Y", and "Character Z" are displayed as material characters. In other words, these three material characters are required for the evolution synthesis of the original "Character A". In addition, the missing material characters (material characters that the user does not yet possess) identified in the processing of step S15 described above are displayed to be distinguished from the other material characters. Here, "Character X", which is the missing material character that the user does not yet possess, is surrounded by a dashed line. Meanwhile, "Character Y" and "Character Z", which are material characters that the user already possesses, are surrounded by a solid line.

[0085] Among the multiple material characters required for the evolution synthesis of the base character specified by the user, the missing material characters that the user does not yet possess are displayed in the missing character display area 504. Here, "Character X" is surrounded by a dashed line as the missing material character, and the number of missing characters is also displayed.

[0086] In this way, users can easily determine which material characters are lacking when performing evolutionary synthesis of their designated base character, "Character A."

[0087] Fig. 11 is an image diagram showing another example of the reservation registration screen. The reservation registration screen 550 shown in Fig. 11 displays an evolved character display area 551, a base character display area 552, a material character display area 553, a missing character display area 554, an operation button 505 for performing reservation registration, and an operation button 506 for reselecting a character.

[0088] The evolved character acquired in the process of step S13 described above is displayed in the evolved character display area 551. Here, "Character S" is displayed as the evolved character.

[0089] The base character display area 552 displays the base character designated by the user in the process of step S12 described above. Here, "Character A" is displayed as the base character. In other words, when evolution synthesis is performed on the synthesis source "Character A", it will evolve into the synthesis destination "Character S".

[0090] In the material character display area 553, a plurality of material characters acquired in the process of step S14 described above are displayed. Here, "Character X", "Character Y", and "Character Z" are displayed as material characters. That is, these three material characters are required for the evolution synthesis of the original "Character A". In addition, the missing material characters (material characters that the user does not yet possess) identified in the process of step S15 described above are displayed to be distinguished from other material characters. Here, "Character Y" and "Character Z", which are missing material characters that the user does not yet possess, are surrounded by a dashed line. On the other hand, "Character X", which is a material character that the user already possesses, is surrounded by a solid line. In addition, since the judgment process of step S17 described above is positive, missing material characters to be synthesized with other base characters are included. Here, the missing "Character Y" and "Character Z" are evolved characters to be synthesized with other base characters ("Character B", "Character C"). The other base characters ("Character B", "Character C") will be described in detail later.

[0091] In the missing character display area 554, among the multiple material characters required for the evolution synthesis of the base character specified by the user, the missing material characters that the user does not yet possess are displayed. In addition, among the other base characters acquired in the processing of the above-mentioned step S16 and the multiple material characters acquired in the processing of the above-mentioned step S17, the missing characters identified in the processing of the above-mentioned step S18 are displayed. Here, as described later, "Character P", "Character Q", and "Character R" are surrounded by dashed lines as the missing characters, and the number of missing characters is also displayed in association with them. Below, the missing characters will be specifically described.

[0092] FIG. 12 is a diagram illustrating the missing characters displayed in missing character display area 554. As shown in FIG.

[0093] In this embodiment, as shown in Fig. 12, the evolved character to be synthesized with the base character "Character A" is "Character S." The material characters required for the evolution synthesis of the base character "Character A" are "Character X," "Character Y," and "Character Z." Of these material characters "Character X," "Character Y," and "Character Z," the missing material characters that the user does not yet possess are "Character Y" and "Character Z."

[0094] In this case, the missing material character "Character Y" is the composite target for another base character "Character B". Also, the missing material character "Character Z" is the composite target for another base character "Character C". Here, it is assumed that the user has the other base characters "Character B" and "Character C".

[0095] The material characters required for the evolution synthesis of another base character, "Chara B," are "Chara P" and "Chara Q." In this case, it is assumed that the user does not possess the material characters "Chara P" and "Chara Q." In addition, the material characters required for the evolution synthesis of another base character, "Chara C," are "Chara P" and "Chara R." In this case, it is assumed that the user does not possess the material characters "Chara P" and "Chara R."

[0096] Here, if the user has the material characters "Character P" and "Character Q", they can obtain the evolved character "Character Y" by performing evolution synthesis with another base character "Character B" that they already have. Similarly, if the user has the material characters "Character P" and "Character R", they can obtain the evolved character "Character Z" by performing evolution synthesis with another base character "Character C" that they already have.

[0097] In other words, if you can obtain "Character Y" and "Character Z" through the previous evolution synthesis, you will have all the material characters, including the "Character X" you already have. As a result, if you use these characters as synthesis materials, you can obtain the evolved character "Character S" by performing evolution synthesis of the base character "Character A".

[0098] Therefore, the characters that are missing to perform evolution synthesis of the base character "Character A" are two "Character P", one "Character Q", and one "Character R". Therefore, in the missing character display area 554, "Character P" (2 characters), "Character Q" (1 character), and "Character R" (1 character) are displayed as the missing material characters.

[0099] In this way, even if evolution synthesis needs to be performed in stages, because the missing material characters ("Character Y" or "Character Z") required for the evolution synthesis of a base character ("Character A") are also the evolved characters to which other base characters ("Character B" or "Character C") are to be synthesized, the missing characters required for each stage of evolution synthesis can be registered as desired acquisition targets all at once. Also, even if the user does not know the existence of other base characters ("Character B" or "Character C"), the user can easily grasp the characters that are missing for the evolution synthesis of the base character ("Character A") that he or she has specified.

[0100] A user who wishes to make a reservation registration performs an operation on the client terminal 10 to select operation button 505 when the reservation registration screen is displayed on the screen display unit 160 of the client terminal 10. On the other hand, a user who does not wish to make a reservation registration and wishes to reselect a character performs an operation on the client terminal 10 to select operation button 506 when the reservation registration screen is displayed on the screen display unit 160 of the client terminal 10.

[0101] The operation reception unit 150 of the client terminal 10 receives an operation for performing reservation registration or an operation for reselecting a character from the user. The request transmission unit 101 of the client terminal 10 transmits a request to the server device 20 based on the operation content received by the operation reception unit 150 from the user.

[0102] Returning to FIG. 5, the reservation registration unit 205 of the server device 20 receives operation contents from the client terminal 10 and determines whether or not an operation for performing reservation registration has been received (step S20).

[0103] If the result of this determination is that an operation to reselect a character has been accepted, the process returns to step S11 and repeats the subsequent steps, whereas if an operation to register a reservation has been accepted, the process proceeds to the next step S21.

[0104] Next, when the reservation registration unit 205 of the server device 20 receives an operation to perform a reservation registration, it performs a reservation registration for the base character specified by the user for the reservation information set in the user information stored in the user information storage unit 222 (step S21).

[0105] FIG. 13 is a configuration diagram showing an example of reservation information. This reservation information has items such as a reservation ID, name, desired evolution target, and desired acquisition target. The reservation ID is information for uniquely identifying an evolution reservation. The name is information indicating the reservation name. The desired evolution target is information indicating the character ID of the base character specified and registered by the user (i.e., the base character displayed in the "base character display area"). The desired acquisition target is information indicating the character ID of the registered missing character (i.e., the character displayed in the "missing character display area"). As shown in parentheses in the figure, the missing quantity is also set.

[0106] In this way, a user can simply specify his / her own base character that he / she wishes to evolve and synthesize, and reserve and register all the characters required for the evolutionary synthesis of that specified base character.

[0107] 《Reservation confirmation》 FIG. 14 is a flowchart illustrating an example of an operation related to reservation confirmation in the information processing system 1 according to this embodiment.

[0108] When the menu screen is displayed on the screen display unit 160 of the client terminal 10, the user performs an operation for confirming the reservation on the client terminal 10. When the user performs this operation, the operation receiving unit 150 of the client terminal 10 receives the operation content based on the user's game operation (step S21).

[0109] The request sending unit 101 of the client terminal 10 makes a request to the server device 20 based on the operation content accepted from the user by the operation accepting unit 150. When the game progression unit 201 of the server device 20 accepts the operation content for confirming a reservation from the client terminal 10, it requests the notification unit 203 to execute notification processing related to the reservation confirmation.

[0110] Specifically, when the notification unit 203 of the server device 20 is requested by the game progression unit 201 to execute notification processing regarding reservation confirmation, it obtains, for each reservation, the base character registered as the desired evolution target from the user's reservation information set in the user information stored in the user information storage unit 222 (step S22).

[0111] Next, the notification unit 203 of the server device 20 refers to the character information stored in the character information storage unit 221, and acquires, for each reservation, an evolved character that is associated with the acquired base character and that is to be a synthesis target (step S23).

[0112] Next, the notification unit 203 of the server device 20 refers to the character information stored in the character information storage unit 221 and obtains, for each reservation, a plurality of material characters (i.e., material characters required for evolutionary synthesis of the base character) associated with the base character obtained in the processing of step S22 described above (step S24).

[0113] Next, the notification unit 203 of the server device 20 refers to the reservation information of the user set in the user information stored in the user information storage unit 222, and obtains the missing characters registered as the target to be acquired and the number of missing characters for each reservation (step S25).

[0114] Next, the notification unit 203 of the server device 20 notifies the user of the possession status and the like of the characters that have been registered in advance as targets to be acquired, based on the various information thus acquired (step S26).

[0115] In this embodiment, the notification is performed using a confirmation screen as shown in Fig. 15. Therefore, when the display control unit 204 is requested by the notification unit 203 to execute screen display control, the display control unit 204 performs control to display the confirmation screen on the screen display unit 160 of the client terminal 10.

[0116] 15 is an image diagram showing an example of a confirmation screen. This confirmation screen 600 displays an evolved character display area 601, a base character display area 602, a material character display area 603, a missing character display area 604, an operation button 605 for canceling a reservation, an operation button 606 for returning to the menu screen, and an operation button 607 for moving to the next reservation.

[0117] The evolved character acquired in the process of step S23 described above is displayed in the evolved character display area 601. Here, "Character S" is displayed as the evolved character for "Reservation 1."

[0118] The base character display area 602 displays the base character designated by the user in the process of step S22 described above. Here, "Character A" is displayed as the desired evolution target for "Reservation 1." In other words, if evolution synthesis is performed on the synthesis source "Character A," it will evolve into the synthesis destination "Character S."

[0119] The material character display area 603 displays the multiple material characters acquired in the process of step S24 described above. Here, the multiple material characters "Character X," "Character Y," and "Character Z" required for the evolution synthesis of "Character A," the desired evolution target of "Reservation 1," are displayed. Additionally, the characters that the user wishes to acquire, acquired in the process of step S25 described above, are displayed to distinguish them from the other material characters. Here, "Character X," the missing material character that the user wishes to acquire, is surrounded by a dashed line. Meanwhile, "Character Y" and "Character Z," material characters that the user already owns, are surrounded by a solid line.

[0120] Among the multiple material characters required for evolution synthesis of the base character as the desired evolution target, the material characters as the desired acquisition target are displayed in the missing character display area 604. Here, "Character X" as the desired acquisition target is surrounded by a dashed line, and the number of missing characters is also displayed in correspondence with it.

[0121] In this way, by looking at this confirmation screen, the user can grasp the possession status of characters that have been registered in advance as targets that the user wishes to acquire. In addition, while this confirmation screen is displayed, the user can select operation button 607 to switch to the next reservation ("Reservation 1" → "Reservation 2" →...), or select operation button 605 to cancel the reservation.

[0122] 《Updating your reservation registration》 FIG. 16 is a flowchart illustrating an example of an operation related to updating a reservation registration in the information processing system 1 according to this embodiment.

[0123] When the user clears a quest, the game progression unit 201 of the server device 20 allows the user to acquire the character granted by the granting unit 202 (Step S31). At this time, the game progression unit 201 updates the user information stored in the user information storage unit 222, thereby setting the granted character as the user's owned character. Then, once the game progression unit 201 of the server device 20 has set the user's owned character, it requests the reservation registration unit 205 to execute a reservation registration update process.

[0124] Next, when the reservation registration unit 205 of the server device 20 receives a request from the game progression unit 201 to execute a reservation registration update process, it acquires the reservation information of the user (see FIG. 13) from the user information stored in the user information storage unit 222. The reservation registration unit 205 references the character information stored in the character information storage unit 221 and determines whether the character granted in the process of step S31 described above is the same character that matches a character previously registered in the acquired reservation information as a desired character to be acquired (i.e., a missing character) (step S32).

[0125] If the result of this determination is that the character is not the same as the character previously registered as a desired acquisition target, this process ends. On the other hand, if the result is that the character is the same as the character previously registered as a desired acquisition target, the process proceeds to the next step S33.

[0126] Next, the reservation registration unit 205 of the server device 20 updates the reservation information set in the user information stored in the user information storage unit 222, and sets it to exclude characters identical to the character granted by the granting unit 202 from the items that the user may wish to acquire (step S33).

[0127] At this time, the reservation registration unit 205 of the server device 20 updates the user information stored in the user information storage unit 222, and registers the excluded character as a protected character (step S34). This makes it possible to protect the excluded character from being used for sale, synthesis, etc., until evolution synthesis of a base character previously registered as an evolution desired target is performed.

[0128] Next, the reservation registration unit 205 of the server device 20 determines whether or not there is a reservation that excludes all characters that have been pre-registered as targets to be acquired, among the multiple reservations set in the user's reservation information (step S35).

[0129] If it is determined that there is no reservation that excludes all characters previously registered as items desired to be acquired, the process proceeds to step S38, which will be described later. On the other hand, if it is determined that there is a reservation that excludes all characters previously registered as items desired to be acquired, the process proceeds to the next step S36.

[0130] Next, if the reservation registration unit 205 of the server device 20 determines that a reservation exists that excludes all characters previously registered as targets to be acquired, it updates the reservation information set in the user information stored in the user information storage unit 222 and cancels the reservation (step S36).

[0131] At this time, the reservation registration unit 205 of the server device 20 updates the user information stored in the user information storage unit 222, and registers the base character that was set as the desired evolution target for the cancelled reservation as a protected character (step S37).

[0132] Next, the reservation registration unit 205 of the server device 20 requests the notification unit 203 to execute the notification process. When the notification unit 203 of the server device 20 is requested to execute the notification process by the reservation registration unit 205, it notifies the user of various information (step S38).

[0133] That is, if the determination is negative in the process of step S35 described above, when the preregistered characters are removed from the desired acquisition targets, the user is notified that the missing characters have been acquired. Also, if the determination is positive in the process of step S35 described above, when the reservation is cancelled due to all preregistered characters being removed from the desired acquisition targets, the user is notified that evolution synthesis of the base character designated by the user (i.e., the base character registered as the desired evolution target) is possible.

[0134] In this embodiment, various information is notified to the user through a notification screen. Therefore, when the display control unit 204 is requested by the notification unit 203 to execute screen display control, the display control unit 204 controls the screen display unit 160 of the client terminal 10 to display the notification screen.

[0135] In this way, the reservation information of the user is updated by being given a character that matches one of the characters previously registered as a desired target. Then, the user is notified that evolution synthesis of the base character registered as a desired target for evolution has become possible by excluding all characters previously registered as desired targets. Then, as the reservation information of the user is updated one after another and the number of characters previously registered as desired targets for acquisition gradually decreases, the user is able to properly grasp the characters that are currently required by the user.

[0136] [Other embodiments] The above-described embodiments are provided to facilitate understanding of the present invention, and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit of the present invention, and equivalents thereof are also included in the present invention. In particular, the following embodiments are also included in the present invention.

[0137] <Composition Game> In the above-described embodiment, an example of a synthesis game was given in which a base character to be synthesized is transformed into an evolved character to be synthesized by synthesizing all of a plurality of material characters that are pre-associated with the base character to be synthesized, but the present invention is not limited to this.

[0138] For example, instead of combining a material character with a base character, a combination game may be executed in which a new character (an evolved character to be combined) is generated by combining all material characters that are related to each other.

[0139] In this case, for example, the character information stored in the character information storage unit 221 is set with a plurality of material characters required to generate an evolved character to be synthesized by synthesis. In response to a user's operation to specify an evolved character to be synthesized, the reservation registration unit 205 refers to the character information and the user information, and pre-registers, as a desired acquisition target, the missing characters that the user does not yet possess, among the plurality of material characters required to generate the specified evolved character by synthesis. Then, in response to the user's operation, the notification unit 203 notifies the user of the possession status of the characters pre-registered as a desired acquisition target, using the confirmation screen 600.

[0140] <Game Type> In the above embodiment, the user may be prompted to specify a missing character displayed in the missing character display area, and the user may be notified of a game type in which the specified missing character can be easily acquired. For example, the notification unit 203 may refer to character information to notify the user of a "quest" in which the specified missing character can be acquired as a game type, or may notify the user of a "lottery game" in which the specified missing character can be acquired by lottery. This makes it possible to easily grasp a game type in which the specified missing character can be acquired.

[0141] In the above-described embodiment, the game type of the pre-registered character that the user wishes to acquire may be notified at a predetermined timing. For example, the notification unit 203 may notify the user of the game type in which the user can acquire the missing pre-registered characters based on the playable days set in the quest information or lottery game information. For example, when Saturday arrives, the user may be notified of the "quest" or "lottery game" in which the user can acquire the missing pre-registered characters.

[0142] <Reservation confirmation> In the above embodiment, an example was given in which the missing characters that were pre-registered as desired acquisition targets for each reservation are displayed in missing character display area 604, and the user can select operation button 607 on confirmation screen 600 to switch to the next reservation and display it, but the present invention is not limited to this.

[0143] For example, it is possible to display all the missing characters for all reservations (characters previously registered as characters desired to be acquired) together in the missing character display area 604 on the confirmation screen 600. For example, assume that in the reservation information, "Character A," "Character B," and "Character C" are previously registered as characters desired to be acquired for "Reservation 1," and "Character B," "Character C," and "Character D" are previously registered as characters desired to be acquired for "Reservation 2." In this case, the missing character display area 604 on the confirmation screen 600 may display a total of "Character A" (missing 1), "Character B" (missing 2), "Character C" (missing 2), and "Character D" (missing 1) (for "Reservation 1" and "Reservation 2" together), so that the user can be notified of their possession status together.

[0144] <Evolution Character Breakdown> In the above-described embodiment, if the missing material character can be obtained by disassembling an evolved character possessed by the user, that evolved character may be set as the protected character.

[0145] For example, if multiple material characters "Character P" and "Character X" are used in evolution synthesis to obtain an evolved character "Character W," when the evolved "Character W" is devolved, "Character W" will disappear from the user's possession, but will be decomposed into the material characters "Character P" and "Character X," which the user can possess. In this case, the confirmation screen 600 of FIG. 14 may notify the user that the missing material character "Character X" can be made up for by decomposing the evolved character "Character W" that the user possesses. Furthermore, in this case, when the user selects the operation button corresponding to "Character X," the evolved character "Character W" may be registered in the user information as a protected character.

[0146] <Protection Registration> In the above embodiment, the case where the character is protected and registered in steps S34 and S37 in FIG. 16 has been described as an example, but it is also possible to omit these processes and not protect and register the character. In this case, the notification unit 203 may warn the user not to use the released character for synthesis or sale at the timing when the user selects the character as a character to be used for synthesis or sale. However, if the user has more characters than are necessary for evolution synthesis, it is also possible not to warn the user.

[0147] <Reservation registration> In the above-described embodiment, an example was given of a case in which a base character designated by a user is pre-registered as a desired evolution target, and any missing material characters required for the evolutionary synthesis of that base character are pre-registered as desired acquisition targets; however, it is also possible to register only the desired acquisition target without registering a desired evolution target. In addition, in the above-mentioned embodiment, among the material characters required for evolutionary synthesis of a base character specified by the user, not only are the missing material characters that the user does not yet possess necessary, but material characters that the user already possesses can also be reserved and registered.

[0148] <Updating reservation registration> In the above embodiment, the processing of step S31 was explained using an example in which the granting unit 202 granted a character in a quest, but the processing can also be applied to a case in which the granting unit 202 granted a character in a lottery game.

[0149] <Contents> In the above embodiment, the content is a character set in the character information, but the content is not limited to this. For example, the content may be an item, a card, a figure, an avatar, etc. [Explanation of symbols]
