Description

  The present invention relates to a game program, a game control method, and an information processing apparatus, and more particularly to a technique for controlling a game in which a plurality of players can participate.

  In recent years, a technology for connecting a terminal such as a smartphone or a tablet to a server and providing a game to a user of the terminal via a network has become widespread. In such a game, in general, a player who is a user of a terminal can operate a character or use an item or the like in the game. These game media such as characters and items are widely provided to players as a reward for a lottery (so-called “gacha (registered trademark)”) for a reward group. Yes.

Japanese Patent No. 5633100

  In general, the reward that the player desires to acquire is often a game medium with a high rare value, and the appearance probability is often set low. For this reason, it is considered that some players have a suspicion that a desired reward can be obtained by a lottery, and the willingness to the lottery may decline.

  Patent Document 1 discloses a technique for maintaining a player's motivation for a lottery by providing a virtual lottery after the player has executed the lottery. However, it is assumed that the conventional lottery is provided individually to each player, and it is considered that there is a limit in maintaining the player's willingness to draw.

  This invention is made | formed in view of such a subject, The objective is to provide the technique which improves the motivation of the player with respect to the reward acquisition provided in a game.

  In order to solve the above-described problem, an aspect of the present invention is a game program for controlling a game in which a plurality of players can participate, and the computer includes two or more players among the plurality of players. A group management function for storing and managing a player group in a storage unit, and when a reward acquisition request is received from a player, a reward is selected for a reward group including a plurality of types of rewards having different appearance probabilities. A specification selection function for providing a player, a specification for reward selection including the appearance probabilities of each of a plurality of types of rewards, stored in the storage unit in association with each player group, and a player group A change acquisition function for accepting a change operation for changing specifications from a constituent player and satisfying a predetermined condition. In the case where points are stored in association with each player, the specification management function is stored in the storage unit in association with the player group when the change acquisition function receives an operation using the points from the player. The appearance probability of a predetermined reward among a plurality of kinds of rewards is changed according to the acquired points.

  The specification management function may further store and manage a reward selection specification including a reward acquisition permission count that sets an upper limit of the number of reward acquisition permitted for each player in the storage unit in association with each player group. Good.

  The reward selection function provides the first reward selection mode in which the reward is determined by reward selection based on the appearance probability determined for each of a plurality of types of rewards, and the upper limit number that can be provided for each of the plurality of types of rewards. In such a case, the reward may be selected in any mode of the second reward selection mode in which the upper limit of the provided reward is reduced.

  In the case where the level of a player rises by satisfying a predetermined condition, the game program corresponds to a player group including the player according to a change operation received from a player with a high level of change acquisition function. You may change the specifications.

  The game program may further have a transmission / reception function for transmitting a display image with an effect different from the normal state based on the reward acquisition.

  When the appearance probability of a specific reward is equal to or higher than a predetermined value in the specification associated with a player group, the group management function can be used even if other players not included in the group participate in the player group. Good.

  Another aspect of the present invention is a game control method for controlling a game in which a plurality of players can participate, wherein a processor group includes two or more players among the plurality of players. When a group management step stored and managed in the storage unit and a request for reward acquisition from the player are received, a reward is selected for a reward group composed of a plurality of types of rewards with different appearance probabilities and provided to the player The specification of the reward selection step, the specification of the reward selection including the appearance probabilities of each of the plurality of types of rewards are stored in the storage unit in association with each player group, and the specifications from the players constituting the player group A change acquisition step for accepting a change operation to change the When the change management function accepts an operation using points from the player, the specification management step stores a plurality of types stored in the storage unit in association with the player group. It changes according to the point which acquired the appearance probability of a predetermined reward among rewards.

  Still another aspect of the present invention provides an information processing apparatus for controlling a game in which a plurality of players can participate, wherein a player group including two or more players among the plurality of players is stored in a storage unit. A group management unit that stores and manages the reward, and when a reward acquisition request is received from the player, the reward selection is made for a reward group composed of a plurality of types of rewards having different appearance probabilities, and the reward selection is provided to the player The specification is changed from the specification management unit that stores and manages the specification of reward selection including the appearance probability of each of the plurality of types of rewards in the storage unit in association with each player group, and the players that constitute the player group The change acquisition unit that receives the change operation to be performed is realized, and points are stored in association with each player by satisfying a predetermined condition In this case, when the change acquisition function accepts an operation using points from the player, the specification management unit calculates the appearance probability of a predetermined reward among a plurality of types of rewards stored in the storage unit in association with the player group. Change according to the acquired points.

  It should be noted that any combination of the above-described constituent elements and the expression of the present invention converted between a method, an apparatus, a system, a computer program, a data structure, a recording medium, and the like are also effective as an aspect of the present invention.

  FIG. 1 is a diagram schematically showing an overall configuration of a game providing system 1 according to the embodiment. The game providing system 1 according to the embodiment includes an information processing apparatus 100, a first terminal 200a, a second terminal 200b, and a third terminal 200c. Hereinafter, in the present specification, the first terminal 200a, the second terminal 200b, and the third terminal 200c are collectively referred to as “terminal 200” unless specifically distinguished. The terminal 200 is communicably connected to the information processing apparatus 100 via the network 300. The information processing apparatus 100 functions as a server that provides a game to the terminal 200. In the example shown in FIG. 1, the game providing system 1 includes three terminals 200, that is, a first terminal 200 a, a second terminal 200 b, and a third terminal 200 c, but the number of terminals 200 is not limited to three, but two Or four or more may be sufficient.

  With reference to FIG. 1, the outline | summary of the game provision system 1 which concerns on embodiment is described. The information processing apparatus 100 according to the embodiment provides the terminal 200 with a game in which a plurality of players can participate through the network 300. The information processing apparatus 100 manages a player group composed of a plurality of players, and executes reward selection for the player group. Note that the user of each terminal 200 becomes a player of a game provided by the information processing apparatus 100.

  Here, “reward selection” is, for example, selection of a reward for a reward group composed of a plurality of types of rewards having different appearance probabilities, and is known as “gacha”. The reward selected by the information processing apparatus 100 is provided to a player who has requested the information processing apparatus 100 to obtain a reward. Thereby, the player can acquire a reward. That is, when the player requests “reward acquisition” from the information processing apparatus 100, the information processing apparatus 100 executes “reward selection” and provides the selected reward to the player.

  The information processing apparatus 100 performs reward selection in units of player groups. The information processing apparatus 100 allows the player to perform a change operation to change the reward selection specification that determines the probability of reward, the number of times each player can acquire the reward, and the like. When the change operation is acquired from the player, the information processing apparatus 100 changes the reward selection specification corresponding to the player group to which the player belongs. Note that the reward selection performed by the information processing apparatus 100 is not limited to a completely random one, but includes ones that are ordered in advance and are selected accordingly. In other words, “reward selection” includes not only lottery among a number of predetermined items, but also provision of a reward to the player based on a predetermined order based on a predetermined rule.

  As described above, the information processing apparatus 100 according to the embodiment selects a reward in units of a player group composed of two or more players. When each player changes the reward selection specification, the change is reflected in the reward selection of the entire player group. Each player can change the reward selection specifications in an advantageous direction for the player group to which the player belongs, in other words, grow “gacha”. The players belonging to the player group cooperate with each other to change the specifications, thereby facilitating exchanges between the players and improving the willingness of each player to acquire a reward.

  Hereinafter, the information processing apparatus 100 according to the embodiment will be described in more detail.

  FIG. 2 is a diagram schematically illustrating a functional configuration of the information processing apparatus 100 according to the embodiment. The information processing apparatus 100 includes a story providing unit 110, a change acquisition unit 120, a specification management unit 130, a reward selection unit 140, a group management unit 150, an event holding unit 160, a transfer operation reception unit 170, a transmission / reception unit 180, and a storage unit 190. Is provided.

  FIG. 2 shows a functional configuration for the information processing apparatus 100 according to the embodiment to provide a game, and other configurations are omitted. In FIG. 2, each element described as a functional block for performing various processes can be configured by a CPU (Central Processing Unit), a main memory, and other LSI (Large Scale Integration) in hardware. In terms of software, it is realized by a program loaded in the main memory. Note that this program may be stored in a computer-readable recording medium or downloaded from a network via a communication line. It is understood by those skilled in the art that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof, and is not limited to any one.

  When the function units of the information processing apparatus 100 illustrated in FIG. 2 are realized by software, the information processing apparatus 100 is realized by executing instructions of a program that is software that realizes each function. As a recording medium for storing this program, a “non-temporary tangible medium”, for example, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. The search program may be supplied to the computer via any transmission medium (such as a communication network or a broadcast wave) that can transmit the search program. The present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the search program is embodied by electronic transmission.

  The search program uses, for example, a script language such as ActionScript or JavaScript (registered trademark), an object-oriented programming language such as C ++, Objective-C, Java (registered trademark), or Ruby, or a markup language such as HTML5. Can be implemented.

  The storage unit 190 stores digital data such as an OS (Operating System) for overall control of the information processing apparatus 100 and a game program provided to the player. The storage unit 190 can be realized by using a known mass storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

  The storage unit 190 stores a game program for controlling a game in which a plurality of players can participate. Examples of such games include MMORPG (Massively Multiplayer Online Role-Playing Game), sports battle games, racing games, battle simulation games, fishing games, and the like. However, the game provided by the information processing apparatus 100 may be any game as long as a plurality of players can participate at the same time, and is not limited to the above.

  Hereinafter, as an example, it is assumed that the game provided by the information processing apparatus 100 is a “fishing game”. Here, the “fishing game” refers to a game in which a target such as a fish displayed on the display screen of the terminal 200 is fished using items such as a carp and bait. In this fishing game, a player who is a user of the terminal 200 can challenge fishing alone, but several players can form a group and challenge fishing together. Hereinafter, in the present specification, a character such as a target “fish” or an item such as a carp or bait may be referred to as a “game medium”.

  The story providing unit 110 reads out and executes the game program from the storage unit 190 and advances the main story of the game. More specifically, the story providing unit 110 executes a fishing game program read from the storage unit 190 and transmits the result to the terminal 200 via the transmission / reception unit 180 and the network 300. Thereby, the target such as fish is displayed on the display screen of the terminal 200.

  The group management unit 150 stores and manages a player group composed of two or more players among a plurality of players in the storage unit 190.

  FIG. 3 is a diagram schematically showing a data structure of the group management table 10 for managing player groups according to the embodiment. The group management table 10 is stored in the storage unit 190 and managed by the group management unit 150. Each player is assigned a player name and a player identifier that can uniquely identify the player.

  Here, the player group managed by the group management unit 150 can be configured by various methods. For example, the story providing unit 110 provides each player with a virtual place for organizing a player group online. The place for organizing the player group is sometimes called “guild” or “town”. The player may recruit members at a place for organizing the player group and organize the player group.

  Alternatively, the group management unit 150 may assign the constituent members of the player group by an arbitrary method (for example, a method of randomly selecting or collecting players with close play time).

  FIG. 3 shows an example in which a player group is composed of N players (N is an integer of 2 or more). The player names of the N players are “first player”, “second player”,... “Nth player”, and the player identifiers are “PID000001”, “PID000002”,... “PID00000N”. is there. The group management unit 150 records and manages the group name assigned to each player group and the player group identifier that can uniquely identify the player group in the group management table 10. In the example illustrated in FIG. 3, the group name of the player group including the N players described above is “GroupABC”, and the player group identifier is “GID000001”. The group management unit 150 manages constituent members in association with each player group.

  The player can acquire game media such as straw and bait used in the game by executing reward acquisition in the game. The reward selection performed by the reward selection unit 140 in response to the reward acquisition may be, for example, a lottery for a reward group including a plurality of types of rewards having different appearance probabilities. The reward selection unit 140 selects a reward to be provided to the player. Here, the reward selection executed by the reward selection unit 140 is a “reward selection specification” that determines which game media are included in the reward group, the appearance probability of each reward, the upper limit of the number of times of reward acquisition allowed for each player, and the like. Is determined for each player group.

  FIG. 4 is a diagram schematically showing a data structure of the specification management table 12 for managing the reward selection specifications according to the embodiment. The specification management table 12 is stored in the storage unit 190 and is managed by the specification management unit 130. As shown in FIG. 4, in the specification management table 12, the number of reward acquisition permission that sets the upper limit of the number of reward acquisition permitted for each player and the appearance probability of each of a plurality of types of reward are associated with each player group. Stored. The specification management table 12 shown in FIG. 4 exemplifies a reward selection specification for a player group whose player group identifier is specified by GID000001.

  As shown in FIG. 4, the specification management table 12 stores the player group identifiers of the players that constitute the player group and the upper limit of the number of rewards allowed for that player in association with each other. In addition, a reward rank indicating the scarce value of the reward is set for each reward constituting the reward group.

  In the example shown in FIG. 4, five reward ranks of rank D, rank C, rank B, rank A, and rank S are defined. The rarity value of the reward rank is set to increase in this order, so the filing probability decreases in this order. More specifically, the appearance probabilities of rewards classified into rank D, rank C, rank B, rank A, and rank S are dd [%], cc [%], bb [%], and aa [%], respectively. , And ss [%], and dd> cc> bb> aa> ss. Further, dd + cc + bb + aa + ss = 100.

  In addition to D, C, B, A, and S, N, R, and SR may be used as the rarity of the reward. Here, N means normal, which means a reward for normal unusualness. R means rare and means a rare reward. SR means (super rare) and means a very rare reward. Therefore, the appearance probability of reward decreases in the order of N, R, and SR.

  When the reward selection unit 140 acquires a reward acquisition request from a player, the reward selection unit 140 reads a specification of reward selection corresponding to the player group to which the player belongs from the storage unit 190. The reward selection unit 140 refers to the read specification for reward selection, and confirms the number of reward acquisition permissions associated with the player identifier of the player who has requested the reward acquisition. If the reward acquisition permission count is 1 or more, the reward selection unit 140 provides the player with reward acquisition. At this time, the reward selection unit 140 performs reward selection based on the appearance probability associated with each reward rank, and provides the player with a reward corresponding to the winning rank.

  The reward selection unit 140 has two types of reward selection modes, a first reward selection mode and a second reward selection mode, and executes two types of reward selection corresponding to the respective reward selection modes. The first reward selection mode is a reward selection mode in which a reward is determined by reward selection based on an appearance probability determined for each of a plurality of types of rewards. Specifically, the first reward selection mode is a reward selection mode for executing reward selection based on the appearance probability stored in the specification management table 12 shown in FIG.

  The second reward selection mode is a reward selection mode in which an upper limit number that can be provided for each of a plurality of types of rewards is determined, a reward to be provided to the player is determined by reward selection, and an upper limit number of the provided rewards is reduced. By determining the number of rewards corresponding to each reward rank, the appearance probability of each reward rank is defined as a result. In this sense, the second reward selection mode also performs reward selection based on the appearance probability determined for each reward, as in the first reward selection mode. However, the second reward selection mode differs from the first reward selection mode in that the appearance probability determined for each reward varies each time reward selection is executed.

  The game provided by the information processing apparatus 100 according to the embodiment allows the player to change the reward selection specification. In order to realize this, the change acquisition unit 120 acquires a change operation for changing the specification of reward selection from the players constituting the player group. The specification management unit 130 changes the reward selection specification corresponding to the player group including the player in accordance with the change operation acquired by the change acquisition unit 120 from the player. More specifically, the specification management unit 130 increases the appearance probability of a predetermined reward or increases the number of reward acquisition permission according to the change operation acquired by the change acquisition unit 120 from the player.

  As described above, the specification management table 12 is used to manage the reward selection specifications for each player group. For this reason, when a certain player changes the specification of reward selection, the change is reflected to the entire player group to which the player belongs. In other words, reward selection / acquisition (gacha) can be grown by all members of the player group. Thereby, the exchange between the members of the player group is activated, and the player's willingness to acquire rewards can be improved.

  The event holding unit 160 holds a game event that participates in units of player groups. More specifically, the event organizer 160 provides a game event to the terminal 200 by reading and executing a game event program from the storage unit 190. There are a plurality of types of game events held by the event organizer 160, and an event identifier that can uniquely identify each game event is assigned to each game event.

  As an example of a game event held by the event organizer 160, there is a big game for the purpose of fishing together with members of a player group. Such an event is known as a so-called “raid battle”. A target in a raid battle is also known as a “raid boss”. The event holding unit 160 holds a plurality of game events with different sizes and types of objects to be picked up. When the player group advances the game event, the event organizer 160 gives a predetermined point to the players constituting the player group. The points given to the player by the event organizer 160 are provided in the form of, for example, virtual currency used in the game or a predetermined item.

  FIG. 5 is a diagram schematically showing the data structure of the event management table 14 for managing game events according to the embodiment. The event management table 14 is stored in the storage unit 190 and is managed by the event holding unit 160. As shown in FIG. 5, the event management table 14 stores an event identifier assigned to each of a plurality of game events and points given to players who have participated in the game event in association with each other. . For example, in the example of the event management table 14 shown in FIG. 5, if the game event is advanced by participating in the game event identified by the event identifier ID000001, the player can obtain the XXX point grant points. Yes.

  It is determined in advance for each game event to which player the event organizer 160 gives points in the player group participating in the game event. For example, the event organizer 160 may give points only to the player who finally picked up the target, or may distribute and give points according to the degree of contribution of each player to the goal achievement.

  The group management unit 150 stores the points given to the player by the event organizer 160 according to the progress of the game event in the storage unit 190 in association with at least one player constituting the player group participating in the game event. .

  FIG. 6 is a diagram schematically showing the data structure of the point management table 16 for managing the points acquired by each player. The point management table 16 is stored in the storage unit 190 and is managed by the group management unit 150. As shown in FIG. 6, the point management table 16 stores a player identifier for specifying a player and a point acquired by the player in association with each other.

  Here, each player can consume the points he / she owns with respect to the change acquisition unit 120 of the information processing apparatus 100 via the network 300, that is, pay points to the change acquisition unit 120. The change acquisition unit 120 acquires an operation in which the player pays points as a change operation for changing the specification of reward selection. That is, when the change acquisition unit 120 acquires points from a player, the specification management unit 130 changes the reward selection specification associated with the player group to which the player belongs.

  As described above, the “reward selection specification” is information that defines which game media are included in a reward group, the appearance probability of each reward, the number of reward acquisitions, and the like. Therefore, the specification management unit 130 changes the specification for selecting a reward, which game media are included in the reward group, the appearance probability of each reward, the reward acquisition permission number, and the like. Means changing information.

  When the reward acquisition permission count is changed as a specification change, the specification management unit 130 acquires the reward stored in the storage unit 190 in association with the player when the change acquisition unit 120 acquires points from the player. Increase the number of permits.

  FIG. 7 is a diagram schematically illustrating a data structure of the number change management table 18 for managing a change in the number of times of reward acquisition permission according to the embodiment. The number change management table 18 is stored in the storage unit 190 and is managed by the specification management unit 130. As shown in FIG. 7, the number change management table 18 stores points necessary for changing the number of times of reward acquisition permission in association with each value of the number of times of reward acquisition permission. In the example of the number change management table 18 illustrated in FIG. 7, in order for a player with zero reward acquisition permission count to increase the reward acquisition permission count to one, it is necessary to pay 1,000 points to the change acquisition unit 120. It is shown that. Further, it is indicated that a player having one reward acquisition permission count needs to pay 10,000 points to the change acquisition unit 120 in order to increase the reward acquisition permission count to two. The same applies hereinafter.

  The specification management unit 130 refers to the number-of-times change management table 18 and acquires a reward acquisition permission number corresponding to the points paid by the player. The specification management unit 130 stores the acquired reward acquisition permission count in the specification management table 12. As described above, when the change acquisition unit 120 acquires a large number of points from the player, the specification management unit 130 stores the specification management table 12 stored in the storage unit 190 in association with the player as compared with the case where the change acquisition unit 120 acquires a small amount. Increase the number of reward acquisition permission in the inside. As a result, the player's willingness to participate in the game event can be increased, and as a result, the exchange between the members of the player group can be promoted.

  When changing the appearance probability of the reward, the specification management unit 130 changes the appearance probability of a plurality of types of rewards in the specification management table 12 when the change acquisition unit 120 acquires points from the player. More specifically, the specification management unit 130 generates a predetermined reward among a plurality of types of rewards in the specification management table 12 stored in the storage unit 190 in association with a player group including a player who has paid points. Change the probability.

  FIG. 8 is a diagram schematically illustrating a data structure of the probability change management table 20 for managing the change in the appearance probability of the reward according to the embodiment. The probability change management table 20 is stored in the storage unit 190 and is managed by the specification management unit 130. As shown in FIG. 8, the number change management table 18 stores points necessary for changing the appearance probability of the S rank reward in association with each value of the appearance probability. In the example of the probability change management table 20 shown in FIG. 8, in order to increase to 0.2 [%] when the appearance probability of the S rank reward is 0.1 [%], the player changes the acquisition unit 120. It is necessary to pay 100 million points. In addition, it is indicated that the player needs to pay 100 billion points to the change acquisition unit 120 in order to increase to 10 [%] when the appearance probability of the reward of S rank is 0.1 [%]. Yes.

  The specification management unit 130 refers to the probability change management table 20 and acquires the appearance probability corresponding to the points paid by the player. The specification management unit 130 changes the appearance probability in the specification management table 12 stored in the storage unit 190 by associating the acquired appearance probability with the player group to which the player who paid the points belongs. In this way, when any player making up the player group pays points, the appearance probability of the S-rank reward increases for all members of the player group. Thereby, the willingness with respect to reward acquisition can be heightened about all the members of a player group. Naturally, when the specification management unit 130 increases the appearance probability of the reward of the S rank, the appearance probability of other reward ranks decreases. Which reward rank appearance probability should be reduced may be determined in advance in consideration of the balance of reward selection / acquisition and the like.

  In addition, when the change acquisition unit 120 acquires a lot of points from the player, the specification management unit 130 increases the amount of increase in the appearance probability of the reward of the S rank as compared to the case where a small amount is acquired. Since the points are obtained by participating in the game event, it is possible to increase the willingness of the player to participate in the game event. As a result, exchange between members of the player group can be promoted.

  For example, a player who is in the leadership position of a player group may wish to grow members of his player group. If another player in the player group can obtain a good game medium (for example, “Persimmon” with good performance or “Bait” with good bite) by acquiring the reward, the level of the player is increased.

  In general, it is considered that a player who is in a leader position has more points than other players. Therefore, the player who is in a leader position changes the specification of reward selection using the points he / she owns. Thereby, the probability that another player in the player group can obtain a good game medium by acquiring the reward can be increased. Accordingly, it is possible to increase the willingness of a player in a leader position to use points for other players. Other players are more motivated to use points to obtain many reward acquisition opportunities. In any case, the exchange between the members of the player group is promoted, and the player's willingness to acquire rewards can be increased.

  Alternatively, even when there is a so-called “friend relationship” in which a certain player and another player in the group are acquaintances, it is considered that a motivation to change the specification of reward selection for each other is born. Even if it is not a “leader”, advanced people in the group may want to grow up for beginners. Even in these cases, a player can be more motivated to use points for other players. Other players are more motivated to use points to obtain many reward acquisition opportunities. Thereby, the exchange between the members of the player group is promoted, and the player's willingness to acquire a reward can be enhanced.

  Note that the specification management unit 130 may increase the amount of change in the appearance probability of the reward as the number of players holding points with respect to the change acquisition unit 120 increases. Thereby, each player's willingness to change the specification of reward selection so that more other players participate in reward acquisition increases. As a result, the player urges other players to participate in the acquisition of rewards, and exchange between players is promoted.

  When changing which game media are included in the reward group, the specification management unit 130 changes the reward that appears in each reward rank when the change acquisition unit 120 acquires points from the player.

  FIG. 9 is a diagram schematically illustrating a data structure of the reward change management table 22 for managing changes of reward items according to the embodiment. The reward change management table 22 is stored in the storage unit 190 and managed by the specification management unit 130. In the reward selection performed by the reward selection unit 140 according to the embodiment, a plurality of game media are classified into the same reward rank. Generally, “goodness” of a reward is divided according to a reward rank, but even a game medium classified into the same reward rank includes a “good” game medium and a game medium that is not.

  Here, the “good” game medium means not only the absolute value and performance of the game medium itself, but also the game medium desired by the player at that time. For example, it is assumed that a plurality of specific game media are collected and “synthesized” to obtain another game media different from the game media. Since what kind of game media is collected and how to use the game media is a player's preference, the value of the game media is also a relative value that varies depending on the player.

  In the reward change management table 22 illustrated in FIG. 9, appearance rewards that are rewards that are actually provided by the reward selection unit 140 are stored in association with each reward rank. For example, in the example of the reward change management table 22 shown in FIG. 9, the item of the reward rank D is the item D1, and the item of the reward rank S is the item S5. Although not shown, the item D2, item D3, and the like exist in addition to the item D1 for the appearance reward of the reward rank D. The same applies to the appearance rewards of other ranks.

  The specification management unit 130 changes the appearance reward in the reward change management table 22 when the change acquisition unit 120 acquires points from the player. The specification management unit 130 may allow the user to select an appearance reward when, for example, the player stores a predetermined amount of points or more in the change acquisition unit 120. In this case, when the points that the player pays to the change acquisition unit 120 are less than a predetermined amount, the specification management unit 130 may change the appearance reward randomly. Alternatively, the specification management unit 130 may request the player for more points in order to change the appearance reward having a higher reward rank as compared to changing the appearance reward having a lower reward rank. Thereby, the willingness with respect to a player's reward acquisition can be heightened.

  FIGS. 10A to 10B are diagrams illustrating examples of display images before and after the change of the reward selection specifications. The display images shown in FIGS. 10A and 10B are generated by causing the graphic processor (not shown) of the information processing apparatus 100 to calculate the reward selection unit 140 by executing the game program.

  FIG. 10A is a diagram illustrating an example of a display image of reward acquisition before the change of the reward selection specification, that is, in a normal state. As shown in FIG. 10A, the display image indicating the reward acquisition is an image imitating a real “capsule toy”. On the other hand, FIG.10 (b) is a figure which shows an example of the display image of reward acquisition after the specification of reward selection is changed. In the example shown in FIG. 10B, a flame is depicted behind the image shown in FIG. 10A, and an effect different from the normal state is made. Thus, the player can grasp at a glance that the specification of reward selection has been changed, and the player's willingness to acquire reward can be enhanced.

  The above describes the case where the player uses the points to increase his own reward acquisition permission count or to change the appearance probability of the reward associated with the player group. In addition to this, it is convenient if the player can transfer the right regarding the reward acquisition possessed by the confidence to another player. Here, the “right related to reward acquisition” means, for example, the number of reward acquisition permission, the above-described points themselves, and the like.

  In order to realize this, the transfer operation accepting unit 170 transfers the right related to the reward acquisition of the first player to the second player configuring the player group in response to the request of the first player configuring the player group. Get a transfer operation. More specifically, when the transfer operation accepting unit 170 acquires a transfer operation from the first player, the group management unit 150 decreases the reward acquisition permission count executable by the first player by a predetermined number, and the second player The executable reward acquisition permission count is increased by the same number as the decreased count and stored in the specification management table 12 in the storage unit 190. Thereby, a certain player can transfer the right regarding the reward acquisition owned by the implementation to another player belonging to the same player group.

  FIG. 11 is a diagram illustrating an example of a GUI (Graphical User Interface) displayed on the terminal 200 possessed by the player when the right to acquire a reward is transferred. As shown in FIG. 11, the player can select the number of reward acquisition permission times to be transferred by tapping the GUI displayed on the terminal 200 and execute the transfer, or cancel the transfer. The GUI shown in FIG. 11 is generated by causing the graphic processor of the information processing apparatus 100 to calculate the transfer operation receiving unit 170 by executing the game program. Although not shown, the transfer operation reception unit 170 generates a GUI for selecting a transfer destination player and transmits it to the terminal 200 before the player executes the transfer. At this time, the transfer operation accepting unit 170 lists up options for the transfer destination player from the player group to which the player belongs, and generates a GUI.

  For example, a player who is in the leader position of the group described above is considered to have a good game medium. Even if it is a reward acquisition that is low in value to be executed for such a player, it may be a reward acquisition that other players want to execute. In such a case, a player who is in a leader position assigns the right for reward acquisition to another player, so that the transferred player can execute reward acquisition. This is advantageous for players who are in a leadership position in that the level of the entire group can be raised, and for other players there is an opportunity to execute reward acquisition that is difficult to execute with confidence. There is a profit. As a result, the player's willingness to acquire rewards can be increased.

  When the probability that a game medium that may change the specification of reward selection appears is high, it is a good opportunity for the player to execute reward acquisition. In such a case, if the player can execute only one reward acquisition with a single operation, the player who wants to acquire a plurality of rewards may feel annoyed.

  Therefore, the reward selection unit 140 allows the player to continuously execute the reward acquisition multiple times with the upper limit of the number of times of reward acquisition permitted stored in the specification management table 12 in the storage unit 190 in association with each player. . Thereby, the troublesomeness which a player feels can be reduced.

  FIG. 12 is a diagram illustrating an example of a GUI displayed on the terminal 200 possessed by the player when the player continuously executes a plurality of reward acquisitions. A user who wishes to execute a plurality of reward acquisitions can continuously execute a plurality of reward acquisitions by one operation by tapping the display screen of the terminal 200.

  In addition, when the specification of reward selection is changed, it is considered that all the players constituting the player group desire to execute reward acquisition. Therefore, the reward selection unit 140 may permit all players making up the player group to obtain rewards at the same timing. The change acquisition unit 120 may reject that the player performs a change operation when the reward selection unit 140 permits all players constituting the player group to acquire the reward at the same timing. As a result, all the members of the player group can obtain a reward all at the same time under the same conditions, and the unfair feeling felt by the player can also be suppressed.

  In particular, when the reward selection unit 140 executes reward selection in the above-described second reward selection mode, the appearance probability of the game media assigned to each reward rank is instantly determined according to the execution of reward selection. Will change. The reward selection unit 140 may display information indicating the appearance probability of the game medium assigned to each reward rank on the terminal 200. Thereby, each player can measure the timing for executing the reward acquisition while checking the change in the appearance probability. Since each player can execute the reward acquisition when the appearance probability of the game medium desired by the confidence increases, the player's willingness to acquire the reward can be improved.

  FIG. 13 is a flowchart for explaining a flow of game control processing executed by the information processing apparatus 100 according to the embodiment. The processing in this flowchart starts when the information processing apparatus 100 is activated, for example.

  The group management unit 150 configures a player group including two or more players among a plurality of players (S2). The group management unit 150 records the configured player group information in the group management table 10 in the storage unit 190. The specification management unit 130 sets a reward selection specification for each of the plurality of player groups (S4). The specification management unit 130 records the set specifications in the specification management table 12 in the storage unit 190.

  Note that the processing order of step S2 and step S4 may be interchanged. In this case, the specification management unit 130 sets a predetermined reward selection specification for a specific player. Thereafter, the group management unit 150 may form a player group with a specific player and another player who participates in response to notification from the player or the server as members. In this case, the information processing apparatus 100 may function as the aforementioned server, or a server (not shown) for recruitment may be prepared.

  The change acquisition unit 120 receives a change operation for changing the reward selection specification from the player (S6). When the change acquisition unit 120 acquires a change operation from the player (Yes in S8), the specification management unit 130 changes the specification of reward selection associated with the player group to which the player who performed the change operation belongs (S10). When the change acquisition unit 120 does not acquire the change operation from the player (No in S8), the specification management unit 130 maintains the reward selection specification without changing it.

  When the reward selection unit 140 receives an instruction to execute reward acquisition from the player, the reward selection unit 140 performs reward selection based on the information in the specification management table 12 recorded in the storage unit 190 (S12). When the reward selection unit 140 executes reward selection in order to provide a reward to the player, the processing in this flowchart ends.

  Note that the information processing apparatus 100 can realize the functions of the above-described units by executing a game program. That is, the story providing unit 110, the change acquisition unit 120, the specification management unit 130, the reward selection unit 140, the group management unit 150, the event holding unit 160, and the transfer operation reception unit 170 described above are configured so that the information processing apparatus 100 stores a game program. By executing, it is realized as a story providing function, a change acquisition function, a specification management function, a reward selection function, a group management function, an event holding function, and a transfer operation reception function.

  As described above, according to the information processing apparatus 100 according to the embodiment, it is possible to improve the player's willingness to acquire rewards provided in the game.

  In particular, the reward selection / acquisition provided by the information processing apparatus 100 according to the embodiment is reflected in the reward selection of the entire player group when each player changes the reward selection specifications. This allows each player to grow reward selection / acquisition for the player group to which he belongs. The players belonging to the player group cooperate with each other to change the specifications, so that exchanges between the players are also promoted, and each player's willingness to acquire a reward can be improved.

  The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .

(First modification)
In the above description, the case where the points used by the player for the change operation are obtained by participating in a game event held by the event organizer 160 has been described. Alternatively or in addition, the player may obtain points by means other than participating in the game event. For example, the player may obtain a predetermined point in return for executing the game. Thereby, the willingness to perform a game by the player who desires execution of reward acquisition can be heightened. Moreover, since the opportunity for reward acquisition is obtained by executing the game, the player's willingness to acquire reward can be maintained.

(Second modification)
In the above description, the case where the information processing apparatus 100 functioning as a server executes a game program and transmits the result to the terminal 200 via the network 300 has been mainly described. However, it is not necessary for the information processing apparatus 100 to execute all the program modules included in the game program. All or at least some of the program modules may be executed on the terminal 200.

  For example, the server executes functions related to reward selection / acquisition such as the change acquisition unit 120, the specification management unit 130, the reward selection unit 140, the group management unit 150, the event holding unit 160, the transfer operation reception unit 170, and the storage unit 190. The story providing unit 110 may be executed by the terminal 200. That is, the main story is executed by the terminal 200 and provided to the player, but the server may provide a function for processing reward selection, group management, and collaborative work in the group.

(Third Modification)
In the above, the case where the specification management unit 130 increases the appearance probability of the reward of the S rank has been described. However, the reward rank that the specification management unit 130 increases the appearance probability is not limited to the S rank, and the appearance probability of other reward ranks may be increased. Also, the player may be able to select which reward rank appearance probability is to be increased. Thereby, the player can increase the appearance probability of the reward rank included in the reward for the acquired game medium, and can improve the player's willingness to acquire the reward.

  Alternatively, the specification management unit 130 may not change the probability of a specific rank, but may present and select the tendency of the probability change to the player. For example, the player selects “S rank emphasis” that changes the appearance probability so that the probability of S rank increases mainly, “normal little eyes” that changes the appearance probability so that the appearance probability of reward with lower rank decreases. You may do it. As a result, even if the request for reward acquisition differs depending on the player, it is possible to respond to those requests in detail. For the player, a motivation to join a group that matches the tendency of reward acquisition desired by the player arises, and as a result, exchange between the players can be promoted.

(Fourth modification)
The group management unit 150 may not allow a new player to participate in the player group when the appearance probability of the reward exceeds a certain value in the reward selection specification associated with a player group. Good. Alternatively, the group management unit 150 may reject the participation of a new player in the player group once the player group is determined. Thereby, it is possible to suppress the player from newly participating in the player group and executing the reward acquisition at the timing when the appearance probability of the reward in the reward acquisition associated with a certain player group increases. It is possible to eliminate a situation in which a player who does not consume points to change the reward selection specification can acquire a reward with a high probability.

(Fifth modification)
The reward selection unit 140 may determine the order in which the player executes reward acquisition according to the amount of points stored. For example, the reward selection unit 140 may provide the player with higher points with higher rewards than the player with lower points. Thereby, the order which carries out reward acquisition according to the contribution degree of the player with respect to the specification change of reward selection can be defined. As a result, it is possible to reduce an unfair feeling related to reward acquisition among players.

(Sixth Modification)
In the above description, the case where the specification management unit 130 changes the specification so that the appearance probability of the reward in the reward acquisition increases. In the case of the second reward selection mode described above, the appearance probability of the reward is changed as a result by changing the specification such as adding or deleting a predetermined item instead of or in addition to this. You may do it.

(Seventh Modification)
In the above, the case where the specification management unit 130 changes the appearance probability of the reward included in each reward rank has been described. Instead of this, the specification management unit 130 may change the appearance probability in units of rewards (for example, specific items) instead of units of reward ranks. Alternatively, when an item to be rewarded has a specific attribute (for example, fire / water / profession), the appearance probability of the reward may be changed using that attribute as a unit. Accordingly, the player can increase the probability that the item desired by the player or the item included in the attribute can be acquired by acquiring the reward, and the player's willingness to acquire the reward can be improved.

(Eighth modification)
In the above description, the case where the reward selection performed by the reward selection unit 140 of the information processing apparatus 100 includes a completely random one, and an order that is selected in advance and includes one that is selected in accordance with the order. The reward selection unit 140 may perform reward selection / acquisition in a combination of a completely random mode and a mode in which the order is determined in advance and the mode is selected accordingly. Specifically, a plurality of rules for providing rewards are prepared, and the reward selection unit 140 randomly selects them according to the player's operation. The reward selection unit 140 may perform reward selection / acquisition according to the selected rule.
