Next, the functions of the game providing system 10 of the present embodiment will be described. FIG. 2 is a block diagram schematically showing the functions of the system 10. As shown in the figure, the system 10 includes an information storage management unit 41 that stores and manages various information, a basic function control unit 43 that controls basic functions, a game progress control unit 45 that controls the progress of a game, and a player. It has a matching processing unit 47 that executes processing related to matching of opponents. These functions are realized by the cooperation of hardware such as the computer processor 11 and the main memory 12 and various programs and data stored in the storage 15 and the like. For example, the main memory 12 This is realized by the computer processor 11 executing the instructions included in the program read in. Further, a part or all of the functions shown in FIG. 2 may be realized by the cooperation of the system 10 and the player terminal 30, or may be realized by the player terminal 30.

The information storage management unit 41 of the system 10 stores and manages various information in the storage 15 and the like. For example, as shown in FIG. 2, the information storage management unit 41 has a player information table 411 that manages information about the player, and a possessed content information table 412 that manages information about the game content owned by the player.

The basic function control unit 43 of the system 10 executes various processes related to the control of the basic function. For example, the basic function control unit 43 transmits screen data or control data of various screens related to the basic function to the player terminal 30, and responds to various operation inputs by the player via the screen displayed on the player terminal 30. Processing is executed, and screen data or control data according to the result of the processing is transmitted to the player terminal 30. Basic functions The basic functions controlled by the control unit 43 include, for example, login processing (user authentication), billing control, and player management (for example, updating the player information table 411).

The game progress control unit 45 of the system 10 executes various processes related to controlling the progress of the game. For example, the game progress control unit 45 transmits screen data or control data of various screens for advancing the game to the player terminal 30, and responds to an operation input by the player via the screen displayed on the player terminal 30. Then, various processes are executed, and screen data or control data according to the result of the process is transmitted to the player terminal 30.

The matching processing unit 47 of the system 10 executes various processes related to player matching. In the present embodiment, the matching processing unit 47 is configured to cluster feature vectors in which features relating to each deck of a plurality of players are vectorized. Clustering is realized by unsupervised learning and divides the set to be classified into subsets (clusters) such that internal connection and external separation are achieved. For example, clustering is realized by applying various methods such as, but not limited to, k-means, topic model, or hierarchical clustering.

In the present embodiment, the feature vector of the deck is configured to include a predetermined component expressing the growth potential of the deck to grow. The growth potential of a deck includes, for example, the growth potential of game content that can be included in the deck. The growth potential of the game content is sometimes referred to as, for example, growth (eg, "strengthening" or "evolution", etc.) with an increase in parameters used in the battle (eg, HP, offensive power, defensive power, etc.). ) Including the possibility. In addition, the growth potential of a deck includes, for example, the growth potential of the deck itself, for example, relaxation of restrictions on configurable game content (for example, expansion of the number of configurable game content / expansion of total cost, etc.). Including the possibility of. The growth potential can also be said to be the degree of expected growth.

Further, in the present embodiment, the matching processing unit 47 selects one or a plurality of other players (competition / cooperative play opponents) to play together with each of the plurality of players based on at least the result of clustering of feature vectors. It is configured to match. For example, the matching processing unit 47 is configured to match opponents based on the cluster to which each of the plurality of players as a result of clustering belongs.

As described above, the game providing system 10 of the present embodiment matches the players based on the result of clustering of the feature vectors in which the features related to the deck are vectorized, so that the matching based on the classification of the deck is possible, and further, the deck Since the feature vector of the above contains a component that expresses the growth potential of the deck, matching that considers the growth potential of the deck becomes possible. In this way, the system 10 assists the player in proper matching.

The game provided by the system 10 of the present embodiment may include various types of games using a deck. In addition, the game content included in the deck may include various game contents such as characters, cards, and items associated with them (for example, equipment items equipped by the character).

In the present embodiment, a predetermined component expressing the growth potential of the deck is included (set) in at least a part of a plurality of game contents owned by the player (for example, among the game contents owned by the player). It corresponds to each of the game contents) and can be configured as a component expressing the nurturing state of the corresponding game contents. Information regarding the development state of the game content is managed in, for example, the possessed content information table 412. Such a configuration enables matching in consideration of the growth potential of the deck based on the development state of the game content.

In addition, the predetermined component is configured so that the current development stage (for example, enhancement level or evolution level, etc.) of the game content and the possibility of promotion to the next development stage are expressed as the development state of the game content. Can be done. For example, the breeding state is expressed as a numerical value consisting of an integer part corresponding to the current breeding stage and a decimal part corresponding to the possibility of promotion. Such a configuration enables matching in consideration of the current development stage of the game content and the possibility of promotion.

In the present embodiment, the promotion possibility of the game content can be set at least based on the satisfaction status of the promotion requirement, which is a necessary condition for advancing to the next development stage. For example, the fulfillment status of the promotion requirement is a predetermined parameter of the corresponding game content, and the predetermined value is required to advance to the next development stage (for example, an experience value for strengthening). , Or the enhancement level for evolution, etc.) includes the current value. Further, for example, the satisfaction status of the promotion requirement is the possession status (for example, player information table 411 or possession content) of the training content (for example, enhancement / evolution item, etc.) necessary for advancing to the next training stage by the player. It is managed in the information table 412). Such a configuration enables matching that takes into account the fulfillment of promotion requirements.

Also, certain components may be configured to represent the growth rate of the corresponding player's deck. The growth rate is set, for example, based on the amount of change in the value of a particular parameter (eg, total strength, strength, HP, etc.) of the player's deck in the past per unit time. Such a configuration enables matching considering the growth rate of the deck.

In addition, the predetermined component may be configured to represent the player's playing performance of the game (eg, playing time and billing amount in a specific period), which is related to the growth potential of the deck. The game play record is managed in, for example, the player information table 411.

In the present embodiment, the matching processing unit 47 clusters the feature vectors of each of the plurality of players before the start of a predetermined event, and divides the plurality of players into a plurality of groups based on at least the result of the clustering. Grouping) and may be configured to match players belonging to the same group during the predetermined event period. The group may be the same unit as the cluster in clustering, or may be a different unit (for example, a plurality of clusters may be integrated into one group, or one cluster may be divided into a plurality of groups. .). Such a configuration prevents players having different deck strengths from being matched, for example, in the latter half of the holding period of an event in which players play against each other / cooperatively.

Next, a specific example of the game providing system 10 of the present embodiment having such a function will be described. The system 10 in this specific example provides a social game in which a quest is executed using a deck composed of a plurality of characters. In addition, as a limited-time battle event in the social game, a battle between players using the same deck is also performed.

FIG. 3 illustrates the information managed by the player information table 411 in this example. The player information table 411 manages information for each player, and as shown in the figure, is associated with a "player account" that identifies an individual player, and an "experience value" that increases according to quest execution (clearing the stage). , "Rank" that gradually increases each time the experience value reaches a predetermined value, "Deck information" that is information about the player's deck, and information about the feature vector in which the features related to the deck are vectorized. It manages information such as "feature vector information", "possessed item information" which is information about items owned by the player, and "event group" which is a group to which the player belongs in a limited-time battle event.

In this example, the deck is composed of two or more characters, and the player selects a predetermined number of characters from the characters owned by the player to form the deck. The deck information of the player information table 411 includes information (for example, character ID) that can identify each of the plurality of characters included in the deck. In this example, the player can set only one deck. However, in another example of the present embodiment, the player can set a plurality of decks (plural variations of decks), and when performing a quest or a match, the set multiple decks You can select the deck to use from among them.

FIG. 4 illustrates the information managed by the possessed content information table 412 in this example. The possessed content information table 412 manages information about a character as game content owned by a player, and as shown in the figure, a "player account" that identifies an individual player and a "player account" that identifies an individual character owned by the player. Information such as "character type" which is the type of character, "equipment item information" which is information about the item equipped by the character, "enhancement level", "evolution stage", etc. in association with the combination with "character ID". To manage.

The character in this example has three stages as evolutionary stages (nurturing stages), and if both of the following two conditions (promotion requirements) are satisfied, it goes up to the next higher evolutionary stage (evolves). be able to.
(1) The enhancement level (predetermined parameter) at the evolution stage has reached the maximum value. (2) You have the types and number of evolution items (cultivation content) necessary for evolution.

When the character evolves, the enhancement level of the character returns to 0, and the required type and number of evolution items are consumed by the player. In this example, the information about the evolution item held by the player is managed in the possessed item information of the player information table 411.

FIG. 5 is a flow chart illustrating a process executed by the system 10 at a predetermined timing (for example, several hours before the start date and time of the event) before the start of the battle event for a limited time. First, as shown in the figure, the system 10 sets the feature vector of the deck of each player participating in the battle event (step S100). In this example, a player who wishes to participate in a battle event needs to register for participation in advance, and in step S100, a feature vector of each deck of a plurality of players who have registered for participation is set.

FIG. 6 is a diagram for explaining the feature vector of the deck in this example. The feature vector in this example is a vectorization of the feature information of the deck, and the feature information is a predetermined number of characters (4 in the example of FIG. 6) constituting the deck and the same predetermined number equipped by each character. Consists of information about equipment items. As shown, the information about the character is the character type, evolution stage, and enhancement level, and the information about the equipment item is the equipment item type.

As shown in FIG. 6, the feature vector has components corresponding to each character and each equipment item. The component corresponding to each character is configured as a vector having dimensions of all kinds of characters in the social game of this example, and among the components of the vector, the component corresponding to the corresponding character type is in the evolution stage. And the growth state parameter which is a numerical value based on the strengthening level is set, while 0 is set for other components.

Specifically, the breeding state parameter consists of an integer part corresponding to the evolutionary stage (any of 1 to 3) and a decimal part corresponding to the strengthening level at that stage. The decimal part is constructed as the ratio of the current value to the maximum value of the enhancement level at that stage. In the example of FIG. 6, since the value of the breeding state parameter set in the component of the vector corresponding to the character 2 is "1.8", the evolution stage of the character 2 is "1", and the enhancement level is The ratio of the current value to the maximum value is "80%" (for example, the maximum value is "50" and the current value is "40"). In addition, the component corresponding to each equipment item is configured as a vector having the dimensions of the number of all types of equipment items in the social game of this example, and corresponds to the type of the corresponding equipment item among the components of the vector. 1 is set for the component, while 0 is set for the other components.

FIG. 7 is a diagram for explaining the relationship between the character's breeding state (evolution stage and strengthening level) and the strength of the character. As shown in the figure, in each of the three evolutionary stages, the strength increases in proportion to the strengthening level, while the evolution timing (specifically, the value of the breeding state parameter reaches 2.0 or 3.0). At (timing), the strength increases stepwise.

Returning to the flow chart of FIG. 5, the feature vector set in step S100 is registered in the feature vector information of the player information table 411. When the feature vector is set in this way, the system 10 then performs clustering of the set feature vector (step S110). Specifically, in this example, clustering is performed by applying the k-means method. The number of clusters in clustering is set to an arbitrary value in advance by an administrator or the like, and for example, a value based on the number of registered participants in a battle event is set.

Subsequently, the system 10 groups the players based on the result of clustering (step S120). Specifically, in this example, an event group is assigned to each player so that the players belonging to the same cluster are in the same group. That is, in this example, the event group is the same unit as the cluster in clustering. The event group assigned to each player is registered in the player information table 411.

In this way, when an event group is set based on the result of clustering of feature vectors of the deck, matching of opponents in the battle event is performed based on the group. Specifically, during the period of the battle event, the opponents are matched so that the players belonging to the same group will play against each other.

In the above example, the feature vector has a component corresponding to each character and each equipment item, and in the component corresponding to the character, the ratio of the current value to the maximum value of the enhancement level is expressed. "Ratio of current value to maximum enhancement level" is an example of the fulfillment status of evolutionary requirements, for example, in place of or in addition to this, of evolutionary items required to evolve. The possession status may be expressed by the component corresponding to the character of the feature vector.

In another example of this embodiment, the growth rate of the corresponding player's deck is represented in the feature vector. FIG. 8 is a diagram for explaining the feature vector of the deck in the other example. The feature information of the deck in this example consists of a predetermined number of characters (4 in the example of FIG. 8) constituting the deck and information on the growth speed of the corresponding player's deck, and the information on the character is the type of character. Is. The feature vector has components corresponding to the growth rate of each character and deck. In this example, the deck growth rate is calculated based on the amount of change in deck strength over a predetermined period and is expressed in three stages (slow, normal, fast).

In FIG. 8, the component corresponding to each character is configured as a vector having dimensions of all kinds of characters, and 1 is set in the component corresponding to the type of the character among the components of the vector. On the other hand, 0 is set for the other components. Further, as the component corresponding to the growth rate of the deck, 1 is set for the corresponding component among the three components corresponding to the three-stage growth rate, while 0 is set for the other components.

In the above-mentioned example, the information about the character included in the deck is illustrated as the feature information of the deck, but in another example of this embodiment, a part or all of a plurality of characters owned by the player (characters not included in the deck) are illustrated. Can also be included.) Information can be applied as deck feature information.

In the above example, the event groups set based on the clustering result of the feature vector of the deck match the same players as opponents, but in other examples of the present embodiment, a plurality of opponents Matching (for example, matching of simultaneous battles by multiple players in the same event group, or matching of league battles by such multiple players) is performed, or one or more cooperative play opponents belonging to the same event group Matching is done.

Since the game providing system 10 according to the present embodiment described above matches players based on the result of clustering of feature vectors in which features related to decks are vectorized, matching based on deck classification is possible, and further, decks can be matched. Since the feature vector of is a component that expresses the growth potential of the deck (for example, the ratio of the current value to the maximum value of the evolution stage and enhancement level of each character contained in the deck), there is a possibility that the deck will grow. Considered matching is possible. In this way, the system 10 assists the player in proper matching.

Further, in the embodiment of the present invention in which matching in consideration of the possibility of deck growth is possible, the matched players can play a fixed number of times or a specific number of times, rather than one-time matching. It is more preferably applied to games that compete or cooperate in a period.
