Description

  The present invention relates to a server device that provides a game using a game medium.

  A so-called online game in which game data is provided from a server device to a terminal device via a network and a game is executed using the game data provided in the terminal device has become widespread. In a card game, which is a type of online game, game media such as character cards and items used in the game are provided to the player. An example of such a card game is disclosed in Japanese Patent Laid-Open No. 2009-187143 (Patent Document 1). A method for selecting a game medium to be provided to a player is disclosed in Japanese Patent Laid-Open No. 2008-93165 (Patent Document 2). In the game described in Patent Document 2, a winning probability is set for each game medium, and provided to the player on the basis of the set winning probability when a game medium acquisition request (purchase request) is made from the player. The game media to be selected is selected.

  A game medium with a low winning probability is called “rare card” or the like. Many games are designed so that the game can be advantageously advanced by using rare cards, and therefore, players often aim to obtain rare cards in games. In order to obtain a rare card having a low winning probability, it is generally necessary to make a game media acquisition request or a lottery request many times.

JP 2009-187143 A JP 2008-93165 A

  In order to make an acquisition request for game media, consumption of in-game points is often a condition. Therefore, if the number of acquisition requests required to acquire a rare card increases, the number of points consumed, etc. Cost also increases. However, in the method of determining the game media to be provided to the player based on the winning probability from a certain population, the number of acquisition requests required until a rare card is obtained can only be predicted probabilistically. The actual cost does not always match the probabilistic prediction (expected value), but rather deviates somewhat from the predicted value. Therefore, the method of determining the game media to be provided to the player from a certain population based on the winning probability provides the player with an accurate prediction of the cost required to obtain the desired game media. I can't.

The instruction input from the player is transmitted to the server device 10 through a browser function of the terminal device 30 or a platform function such as NgCore (trademark).

Next, functions of the server device 10 realized by the components shown in FIG. 1 will be described with reference to FIG. FIG. 3 is a block diagram illustrating functions of the server device 10 according to an embodiment of the present invention. As shown in FIG. 3, the server device 10 according to the present embodiment includes a game progress control unit 51.
A deck identification information storage unit 52, a stored game content information storage unit 53, a winning game content selection unit 54, an update unit 55, an owned game content information storage unit 56, an initialization processing unit 57, and a stored game A medium information providing unit 58. Although a detailed description is omitted, the server device 10 may include a charging processing unit that performs a player authentication process at the start of the game and a charging process that occurs in accordance with the progress of the game. These functions are realized by loading a predetermined program into the main memory 12 under the control of the CPU 11, and the CPU 11 executing an operation based on a command of the program.

  The game progress control unit 51 can control the progress of the game for each player by transmitting and receiving various data necessary for the progress of the game to and from the terminal device 30 and managing such data for each player. . For example, the game progress control unit 51 causes the terminal device 30 to sequentially display web pages constituting a website that provides a game service in response to a request from the terminal device 30. When the player selects a hyperlink on the displayed web page, the game progress control unit 51 transmits new HTML data corresponding to the hyperlink to the terminal device 30. On the terminal device 30, a web page based on the new HTML data is displayed. Thus, the game progress control unit 51 sequentially provides the web pages stored in the server device 10 to the terminal device 30 in accordance with the operation of the player, so that the player progresses the game through the operation of the terminal device 30. Can be made.

  When a game application is executed on the terminal device 30, the game progress control unit 51 can transmit various data used in the game to the game application. For example, when the game progress control unit 51 receives a control signal indicating that a predetermined mission has been cleared from the game application of the terminal device 30, the game progress control unit 51 sets various parameters related to the next mission of the cleared mission to the game application. Provide against. The game application can load the data provided from the server device 10 and advance the game.

The terminal device 30 determines whether the game progresses such as information indicating various parameter values used in the game (such as information regarding the number of game points acquired and information regarding acquired items) and information indicating the status (such as information specifying an accomplished mission). Can be appropriately transmitted to the server device 10 using the function of the browser software or the game application. The game progress control unit 51 can control the progress of the game for each player by storing information related to the progress of the game received from the plurality of terminal devices 30 for each player. Thus, when the player logs in to the server device 10 using his / her ID, the player's progress is determined based on the information about the progress of the game associated with the player held in the server device 10. The game is resumed from the last scene (for example, the scene just before the interruption). As will be described later, the information necessary for the progress of the game is not limited to the game progress control unit 51, but the server device.
Can be managed by 10 different functions.

  In the terminal device 30, various games are executed. In the game executed on the terminal device 30, various game media such as an electronic card, an item, and a virtual currency usable in the game are used. The game medium is a general term for electronic data used by the player for the progress of the game, and includes, for example, a card, an item, a character, and an avatar. In one aspect of the present invention, the game medium can be acquired, held, used, managed, exchanged, combined, enhanced, sold, discarded, and / or gifted, etc., by the player in the game as the game progresses. The usage mode of the game media is not limited to those specified in this specification. When selling a card in a game, not a real currency but a virtual currency used in the game may be paid to the player as a price for selling the card. For example, attribute information (for example, “rarity”, “level”, “attack”, “defense”, “game media name”, etc.) that is referred to as appropriate in the progress of the game is set in the game media. Is done. At least a part of these attribute information can be updated as the game progresses. The player can advance the game using a game medium having updated attribute information. For example, in a card game, a player holds one or a plurality of cards in the game, and uses the held cards to capture a mission or use the cards to play against other players or non-player characters. By doing so, the game can be advanced. The present applicant offers various types of card games on the Mobage (R) platform.

  The game media used in the game in the embodiment of the present invention are managed in the server device 10 in units called game media storage decks (sometimes referred to simply as “deck” in the present specification), and each player Can acquire the game media stored in the deck assigned to him / her through the terminal device 30, and can proceed with the game using the acquired game media. The deck contains a finite number of game media. A deck is individually assigned to each player of the game. The game media stored in the deck may be different for each player, and a deck storing the same game media may be assigned to each player.

The deck identification information storage unit 52 stores deck identification information for identifying a deck assigned to the player in association with player identification information for identifying each player. The deck identification information storage unit 52 is realized by, for example, a deck identification information management table provided in the external memory 15 or an external database server. FIG. 4 shows an example of the deck identification information management table. As illustrated, in the deck identification information management table, deck identification information for identifying a deck assigned to the player is stored in association with player identification information for identifying each player. In the example shown in FIG. 4, in association with the player identification information “000001”
Deck identification information “D000001” is stored.

“Player identification information” is an identification code for identifying a player of the game, and is composed of, for example, a 6-digit decimal number. The code system of the player identification information is not limited to that specified in this specification, and an arbitrary code system can be used as the player identification information. For example, the player identification information can include alphabets. For example, the player identification information is assigned to a player when the player logs in or registers for the first time in the game, and the player usually continues to use the same player identification information at the time of re-login. Thus, the player identification information is identification information unique to each player for identifying each player in the game. “Deck identification information” is an identification code for identifying a deck used in the game, and is composed of, for example, an alphabet and a 6-digit decimal number. The code system of the deck identification information is not limited to that specified in this specification, and an arbitrary code system can be used as the deck identification information.

Information relating to the game media stored in each deck (hereinafter also referred to as “accommodated game media information”) is stored in the stored game media information storage unit 53. The stored game content information storage unit 53 is realized by a stored game content information management table provided in the external memory 15 or an external database server, for example. FIG. 5 shows an example of the stored game content information management table. As shown in the figure, the stored game content information management table stores stored game content information related to one or more game media stored in the deck identified by the deck identification information in association with the deck identification information. . The stored game medium information includes game medium identification information for identifying a game medium (or its type) stored in the deck, a “rareness value”, a “total stored number”, and a “accommodated number” of the game medium. Can be included.

“Game medium identification information” is an identification code for identifying a game medium (or its type) held by the player, and is composed of, for example, a combination of an alphabet and a 6-digit decimal number. The code system of the game medium identification information is not limited to that specified in this specification, and an arbitrary code system can be used as the game medium identification information.

The “rareness value” of a game medium is an index indicating the difficulty of obtaining the game medium, and takes a value from “1” to “4” in the embodiment of FIG. In the illustrated embodiment, it is assumed that the smaller the rarity value of the game medium, the easier it is to obtain the game medium, and the greater the rarity value, the harder it is to obtain. On the contrary, the rarity value may be set so that the game content becomes easier to obtain as the rarity value of the game content increases.

In order to make it difficult to obtain the game content as the rarity value of the game content increases, various methods can be used. For example, in the embodiment of FIG. 5, the larger the game media rarity value, the smaller the number of game media accommodated in the deck. As a result, by randomly selecting the game media to be provided to the player from the game media stored in the deck, the game media having a higher rarity value are less likely to be selected. In addition, when the game media to be provided to the player is selected from the game media stored in the deck, the winning probability is weighted for each game media so that the greater the rarity value, the lower the probability of selection. Thus, a game medium having a higher rarity value can be made difficult to select. Even if the rarity value of the game media is not set, game media with special effects in the game, or game media with the same or other types of game media added ( Or the like may be reduced so that these game media are not easily selected.

The “total number of stored game media” indicates the number of game media stored in each deck in the initial state of the deck. As described above, it is possible to determine the “total number of pieces accommodated” of each game medium such that the higher the rarity value of the game medium, the smaller the number of game media accommodated in the deck. In the example of FIG. 5, the game medium identified by the game medium identification information “M000001” having the lowest rarity value set to “1” (hereinafter referred to as “game medium 1” or the like) may be used. ) And the game media identification information “M000005” are set to “50”.
On the other hand, the total number of game media (game media 4) identified by the game media identification information “M000004” set to “4” having the highest rarity value is set to “1”. Therefore, if a game medium is randomly selected from the game contents stored in the deck, the probability that the game medium 4 is selected is 1/50 of the probability that the game medium 1 is selected (game medium). The comparison with 5 is also the same).

The “accommodated number” of game media indicates the number of game media remaining in the deck after a winning game media to be described later is provided to the player. As will be described later, the game media selected as the winning game media among the game media stored in the deck identified by the deck identification information “D000001” (hereinafter sometimes referred to as “deck 1”) Provided to the player identified by the player identification information “000001” (hereinafter sometimes referred to as “player 1”). The “accommodated number” of the game media is calculated by subtracting the number of the game media provided to the player from the “total accommodated number” of the game media. The remaining number of game media in the deck calculated in this way is stored in the “accommodated number” area of the accommodated game media information management table.

The “name” of the game medium represents a name set for the game medium. “Name” is an example of game content attribute information indicating an attribute of the game content. Although not shown in FIG. 5, various game medium attribute information other than “name” can be stored in the stored game medium information management table. The game media attribute information includes, for example, various information such as an image of the game media, attribute values such as attack power and defense power set in the game media, and experience values acquired by using the game media in the game. Such information can be stored in the stored game content information management table.

  FIG. 5 shows the stored game media information stored in association with the deck identification information “D000001”. Similarly, other deck identification information is also associated with each deck identification information. The stored game content information is stored. The stored game content information stored in other decks may be the same as or different from the stored game content information of the deck 1.

In response to a game media acquisition request from a player, the winning game media selection unit 54 selects one or a plurality of winning games from the game media stored in the deck assigned to the player according to a predetermined lottery algorithm. Select the medium. For example, when a game medium acquisition request is acquired from the terminal device 30 of the player 1 in the server device 10 by the player 1 performing an operation input to the terminal device 30, the player is displayed in the deck identification information management table of FIG. A deck identification number “D000001” associated with the player identification number “000001” of 1 is specified, and a winning game medium is selected from the game contents stored in the deck 1 identified by the deck identification number “D000001” Is selected. If the deck 1 is assigned only to the player 1 as in the example of FIG. 4, even if a game media acquisition request is received from a player other than the player 1, the winning game is selected from the game media stored in the deck 1. No game media is selected.

In one embodiment, the winning game media is randomly selected from the game media stored in the deck using, for example, pseudo random numbers. In the embodiment illustrated in FIG. 5, the total number of game media accommodated is 100 (32 game media 1, 21 game media 2, 9 game media 3, and game media 4 1 game game, 29 game media, and 8 game media 6 (the total of these is 100).) Each game media win probability is 1/100. In this case, a game medium having a large number of pieces can be easily selected as a winning game medium. For example, the game media 1 and the game media 5 having a small rarity value are easy to be selected because they have a large accommodation number, and conversely, the game media 4 having a large rarity value are difficult to be selected because they have a small accommodation number. In this way, in the example shown in FIG. 5, the game media having a higher rarity value has a smaller number of pieces to be accommodated. An example of a game medium with a large rarity value such as the game medium 4 is a “rare card”.

In another embodiment, the winning probability can be set according to the rarity value of the game medium so that the probability of selection decreases as the rarity value increases. The winning game content selection unit 54 selects a winning game content based on the set winning probability. As a result, the probability that a game medium with a higher rarity value will be selected has a lower probability. Therefore, the larger the rarity value, the less likely it is to be selected as a winning game medium.

The winning game medium selecting unit 54 may select one winning game medium in response to a single game medium acquisition request from the player, and simultaneously select two or more arbitrary winning game contents simultaneously or sequentially. You may choose. In order to realize such a function, in one aspect of the present invention, the game medium acquisition request can include the number of game media that the player desires to acquire. At this time, the number of game media desired to be acquired can be set to an arbitrary natural number that is equal to or less than the total number of game media stored in the deck. In one embodiment, an input field for inputting the number of game media desired to be acquired can be provided on a web page for generating a game media acquisition request (see FIG. 8). The player can input a desired number in the input field by operating the terminal device 30. In the game content acquisition request, the number input in the input field is set as the number of game media desired to be acquired. In another aspect, it is possible to request acquisition of all the game media stored in the deck by the player's selection. In this case, a web page for generating and transmitting an all game media acquisition request for acquiring all the game media accommodated in the deck can be transmitted from the server device 10 to the terminal device 30. The web page is provided with an operation button for generating an all game media acquisition request. When the player selects the operation button by operating the terminal device 30, a game media acquisition request including the all game media acquisition request is generated. Generated.

The update unit 55 deletes the winning game media selected from the game media in the deck by the winning game media selection unit 54 from the deck. For example, in the example shown in FIG. 5, when one game medium 1 is selected by the winning game medium selection unit 54, the “accommodated number” stored in association with “M000001” is changed from “32”. Decrease to “31”. As a result, one game medium 1 is deleted from the deck 1. As described above, in this specification, when the winning game media is deleted from the deck, it includes reducing the number of the winning game media to be stored. When a plurality of winning game media are selected, the accommodation number associated with the winning game media in the deck is decreased by the selected number. For example, when three game media 1 are selected as winning game media by the winning game media selection unit 54, the “accommodated number” stored in association with “M000001” is changed from “32” to “29”. To decrease. Thus, the update unit 55 deletes the winning game media selected by the winning game media selection unit 54 from the deck, thereby updating at least a part of the stored game content information obtained in association with the deck. be able to.

The possessed game medium information storage unit 56 can store one or a plurality of game media possessed by the player in the game in association with player identification information for identifying each player. The possessed game content information storage unit 56 is realized by, for example, a retained game content management table provided in the external memory 15 or an external database server. FIG. 6 shows an example of the owned game media management table. As shown in the figure, the possessed game media management table stores game media identification information for identifying five game media possessed by the player and the number of each game media possessed in association with player identification information for identifying each player. Has been. In FIG. 6, “N / A” is indicated when there is no game medium to be held.

The possessed game media information storage unit 56, when the winning game media is selected by the winning game media selection unit 54 in response to a game media acquisition request from the player, is used as the game media held by the player Remember. For example, in the example shown in FIG. 6, when the game medium 1 is selected as a winning game medium in response to a game medium acquisition request from the player 1, it corresponds to the player identification information “000001” in the owned game medium management table. The number of attached game media 1 is updated from “8” to “9”. As described above, when one or more game media already held as the winning game media are selected, the number of the game media held is increased by the number of the game media selected as the winning game media. For example, when one game medium 1 is selected as the winning game medium, the number of game media 1 held in the owned game medium management table is increased by “1”. When three game media 1 are selected as the winning game media, the number of game media 1 held in the owned game media management table is increased by “3”. When a game medium not owned by the player 1 is selected as the winning game medium, game medium identification information for identifying the winning game medium is stored in association with the player identification information “000001” of the player 1. For example, in the example of FIG. 6, when the game medium 4 is selected as the winning game medium in response to the game medium acquisition request of the player 1, “owned item 5” associated with the player identification information “000001”
In this area, game medium identification information “M000004” for identifying the game medium 4 and “1” which is the number of the game medium are registered.

  The owned game content management table can be updated as needed as the game progresses, in addition to the case where the winning game content is selected by the winning game content selection unit 54. For example, when the player plays a game and acquires a game medium such as a weapon item, it is stored in the owned game medium management table in association with the player identification information of the player who acquired the game medium. When the player newly acquires a game medium such as a weapon item, the possessed game medium information storage unit 56 stores game medium identification information for identifying the newly acquired game medium, and the player of the player who has acquired the game medium. Corresponding to the identification information, it is stored in the possessed game media management table. When the player exchanges game media with another player, the owned game media management table is updated to reflect the exchange.

The initialization processing unit 57 can perform an initialization process for initializing the deck in response to a predetermined initialization condition being satisfied. For example, (a) the game medium having the highest rarity in the deck is selected as the winning game medium (initialization condition (a)), (b) all game media stored in the deck. (C) When the deck is started to be used, registered for use in the game, on time (
For example, a predetermined time has elapsed from a predetermined time point (initialization condition (c)), (d)
The server device 10 has acquired a predetermined number of game media acquisition requests from the player to which the deck is assigned (initialization condition (d)), and (e) a predetermined number of winning game media have been selected (initial The initialization conditions applicable to the present invention are not limited to these.

When any of these initialization conditions is satisfied, the initialization processing unit 57 initializes the deck. Deck initialization refers to setting or updating a deck so that the number of game media accommodated in the deck is equal to the total number of games. As described above, the deck in the embodiment of the present invention is configured such that when a winning game medium is determined in response to a game medium acquisition request from a player, the winning game medium is deleted from the deck. At this time, the number of stored game media is reduced by the number corresponding to the number of winning game media. Therefore, the deck is initialized by supplementing the deleted game game media to the deleted game media. Various methods can be used to initialize the deck. In particular, the initialization of the deck in the present invention is not limited to supplementing the deleted winning game media in the deck. For example, the initialization processing unit 57 can replenish a game medium having the highest rarity value (for example, the game medium 4) instead of a game medium having a lower rarity value. As a result, it is possible to limit the number of game media distributed with the highest rarity value. In one aspect of the present invention, a web page for generating and transmitting an initialization request to the terminal device 30 when any of the initialization conditions (a) to (e) is satisfied. The deck can be initialized when the transmission request is received and the initialization request generated based on the operation of the web page by the player is acquired.

If the game media with the highest rarity value in the deck is selected as the winning game media as specified in the initialization condition (a), a card with a higher rarity will be used even if the deck is used continuously. Since the possibility of acquisition becomes extremely small (in the example of FIG. 5, when game medium 4 is selected, game medium 4 does not exist in the deck, and there is no possibility of additional acquisition of game medium 4). In such a case, the deck is initialized. Since the initialized deck contains up to the maximum number of game media with a large rarity value, the initialization process improves the selection probability of game media with a large rarity value than before initialization. Can be made. Thereby, even after a game medium having a large rarity value is selected, the player's interest can be continuously attracted.

  In addition, when any of the initialization condition (b) to the initialization condition (e) is satisfied, many game media have already been deleted from the deck, and the game media remaining on the deck is biased. May have occurred. Therefore, the initialization processing unit 57 initializes the deck when any of the initialization conditions (b) to (e) is satisfied for a predetermined deck. Thereby, it is possible to correct the bias of the game media stored in the deck.

  When the player plays the game for the first time, the initialization processing unit 57 can assign an initialized deck to the player. As described above, the initialization of the deck means that the number of game media accommodated in the deck is equal to the total accommodated number. For example, the server device 10 has a plurality of types of game media different from each other. The initialization processing unit 57 can also randomly assign the plurality of types of decks to the player, for example. Further, in addition to the deck being used, the initialization processing unit 57 can set the same deck as the deck being used or a different deck. When the additional deck is put into use for a predetermined player, the winning game media selection unit 54 selects the game media contained in the originally used deck and the game media contained in the added deck. Then, the winning game media is selected. In this way, by adding another deck to the deck in use, the total number of game media that can be selected by the winning game media selection unit 54 can be increased. Further, by adjusting the total number of game media accommodated in the added deck, the probability that a game media having a large rarity value is selected can be kept constant.

  The stored game content information providing unit 58 can provide at least part of the stored game content information stored in the deck identification information storage unit 52 to the terminal device 30 of the player. For example, the stored game content information providing unit 58 may include a part or all of the “rareity value”, “name”, “total stored number”, and “accommodated number” of each game content stored in the stored game content information management table. Can be generated, provided to the terminal device 30, and displayed on the terminal device 30. An example of this display is shown in FIG. A display example of FIG. 10 will be described later.

Next, with reference to FIG. 7, an example of processing for selecting a winning game medium in one embodiment of the present invention will be described. FIG. 7 shows an outline of the process from the start of the game provided by the server device 10 until the process of updating the deck according to the selection of the winning game medium is completed and the deck is initialized as necessary. FIG. Here, a case where a winning game medium is selected from the game media stored in the deck 1 based on a game medium acquisition request from the player 1 will be described as an example.

First, when the game is started in step 702, the player operates the terminal device 30 to access the server device 10, and obtains a desired web page from among a plurality of web pages constituting the game site. When the player selects a link to a web page for making a game content acquisition request in order to acquire a game content, for example, a display screen as shown in FIG. FIG. 8 is an example of a display screen for prompting the game player to generate a game medium acquisition request and transmit it to the server device 10. The terminal device 30 acquires HTML data corresponding to a web page for making a game media acquisition request from the web pages constituting the game site from the server device 10, and analyzes the HTML data to obtain FIG. The illustrated game medium acquisition request screen can be displayed.

When the player operates the terminal device 30 and selects an operation button displayed as “Request acquisition” in the game medium acquisition request screen, the terminal device 30 generates a game medium acquisition request, and the generated game medium An acquisition request is transmitted to the server device 10. The game medium acquisition request includes, for example, player identification information of the player 1. Subsequently, in step 704, the server device 10 acquires the game medium acquisition request transmitted from the terminal device 30 of the player 1. next,
Proceeding to step 706, in response to the acquired game media acquisition request, the winning game media selection unit 54 refers to the deck identification information management table to identify the deck 1 assigned to the player 1, and this deck 1 The winning game media is selected from the game media accommodated in accordance with the predetermined lottery algorithm described above. For example, when one game medium 1 is selected as the winning game medium, a web page corresponding to the display screen of the winning game medium shown in FIG. 9 is generated and generated for the terminal device 30 of the player 1 The web page thus transmitted is transmitted to the terminal device 30 of the player 1. The terminal device 30 of the player 1 analyzes the received web page and displays a display screen including a winning game medium as illustrated in FIG. The user can check which game media has been selected as the winning game media by lottery by viewing the display screen of FIG.

Note that the server device 10 may store game points acquired by each player in the game and points that can be used in a plurality of games purchased from the game provider in association with the player identification information of the player. it can. Based on the game medium acquisition request acquired from the player 1, the server device 10 can update points such as game points stored in association with the player identification information of the player 1. For example, in the example shown in FIG. 8, it is shown that 100 game points are consumed by one game medium acquisition request. When the game media acquisition request generated from the web page shown in FIG. 8 is acquired,
100 points can be subtracted from the game points held by the player 1.

Next, proceeding to step 708, the game medium 1 selected as the winning game medium is the player 1
Will be added to the owned game media. Specifically, the possessed game content information storage unit 56 updates the retained number of players 1 stored in the retained game content management table of FIG. 6 so as to increase by “1”. As shown in FIG. 6, before the player 1 sends a game media acquisition request,
When the game media 1 are held, the held game media management table is updated so that the number of game media 1 held is nine.

Next, proceeding to step 710, the game media 1 selected by the winning game media selection unit 54 is deleted from the deck 1 by the update unit 55. One game medium 1 is a winning game medium selection unit 54
In the case of the selection, the updating unit 55 sets the “accommodated number” stored in association with the game medium identification information “M000001” of the game medium 1 in the stored game medium information management table of the deck 1 to “32”. To "31".

The stored game content information providing unit 58 generates a web page including the stored game content information stored in the updated stored game content information management table, and transmits the generated web page to the terminal device 30 of the player 1 Can do. FIG. 10 is a display example on the terminal device 30 of the display screen corresponding to the web page including the updated stored game content information. As shown, the figure
In the ten display screens, the game media name and the number of game media contained are displayed in association with each other among the game media information of the updated game media. Of these, for game media 1, with the name “Card A”, the notation “32”, which is the number of accommodation before the update, and the notation “31”, which is the number of accommodation after the update, They are displayed in association with each other. For game media other than game media 1, names such as “card B” and the number of stored media are displayed in association with each other. This web page may include the total accommodated number and the total accommodated number in the display screen of FIG. 10 including the total accommodated number. In this way, by displaying the stored number in association with the total stored number, it is possible to determine how many game media have already been selected as winning game media (or deleted from the deck) among all game media included in the deck. It is easy to understand and can be presented to the player.

Next, the process proceeds to step 712, where it is determined whether any of the initialization conditions stored in the server device 10 is satisfied. Specific examples of initialization conditions have been described above. If none of the initialization conditions are satisfied, the process proceeds to step 716. On the other hand, when any one of the initialization conditions is satisfied, the process proceeds to step 714, and the initialization processing unit 57 initializes the deck 1. For example, the deck 1 is initialized by updating the stored game medium information so that the stored number of each of the game media 1 to 6 is equal to the total stored number. In step 714, when any of the above-described initialization conditions is satisfied, a web page for generating and transmitting an initialization request is transmitted to the terminal device 30, and the web page by the player is transmitted. When the initialization request generated based on the operation is acquired from the terminal device 30, the deck 1 may be initialized.

  Next, in step 716, if the game 1 is not finished by the player 1, the process returns to step 704 and waits until another game media acquisition request is acquired from the terminal device 30 of the player 1. When another game media acquisition request is acquired, the processes in steps 706 to 716 described above are executed again. When the player 1 performs a game end operation, the game is ended for the player 1.

  As described above, according to one embodiment of the present invention, a deck that accommodates a finite number of game media is individually assigned to each player. Based on the game media acquisition request from each player, the winning game media is selected from the game media stored in the deck assigned to the player, and the selected winning game media is provided to the player. At the same time, it is deleted from the deck assigned to the player. Therefore, each player sequentially obtains winning game media from a limited number of predetermined game media, so if you refer to the history of the winning game media obtained so far, it will remain in its own deck. It is possible to grasp the type and number of game media being played. For example, if a large number of game media having a low rarity value have been acquired in the past, it can be understood that the proportion of game media having a high rarity value has increased in the deck. In addition, as shown in FIG. 10, by displaying the number of game media accommodated on the player's terminal device, the player can be informed directly of the type and number of game media remaining in the deck.

In this way, by assigning a deck that accommodates a finite number of game media to each player individually and deleting the game media provided to the player from the deck, the player remains in the deck. The type and number of game media can be grasped. Therefore, the player can more accurately predict the number of game medium acquisition requests required until a desired game medium such as a game medium having a high rarity value stored in the deck is acquired. And the cost which increases according to the frequency | count of game media acquisition requests, such as the number of consumption points, can be correctly estimated based on the predicted value of the frequency | count of a game media acquisition request. For example, as shown in the stored game content information management table of FIG. 5, a total of 100 game media are stored in the deck, and only one game media 4 with the highest rarity value is included. It is understood that the game media having the highest rarity value can be obtained by making a game media acquisition request at most 100 times.

Next, a server device according to another embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a plurality of different decks can be assigned to each player. In the present embodiment, the deck identification information management table shown in FIG. 11 is used instead of the deck identification information management table shown in FIG. 4, and the accommodation game shown in FIG. 12 is used instead of the accommodation game medium information management table shown in FIG. A medium information management table is used. The server device according to the present embodiment has substantially the same configuration as that of the embodiment shown in FIGS. 1 to 10 except for the configurations of the deck identification information management table and the stored game content information management table. Except for the processing that uses, substantially the same processing as the embodiment shown in FIG. 1 to FIG. 10 is performed, and therefore, the detailed description of the parts common to the embodiment shown in FIG. 1 to FIG. 10 is omitted. To do.

  FIG. 11 shows an example of a deck identification information management table provided in the server device 10 according to the present embodiment or a database communicably connected to the server device 10, and FIG. 12 shows the server device 10 according to the present embodiment. Alternatively, an example of a stored game content information management table provided in a database communicably connected to the server device 10 is shown. FIG. 13 is a flowchart showing an outline of processing provided by the server device according to the present embodiment.

As shown in FIG. 11, the deck identification information management table according to the present embodiment includes deck identification information for identifying one or a plurality of decks assigned to the player in association with player identification information for identifying each player. Remember. For example, in the deck identification information management table of FIG. 11, two types of decks identified by the deck identification information “D000001-1” and “D000001-2” are associated with the player identification information “000001”. ing. For example, the deck identified by the deck identification information “D000001-2” (Deck 1-2) has a greater rarity value than the deck identified by the deck identification information “D000001-1” (Deck 1-1). The total number of game media accommodated is increased. For example, in the deck 1-2 shown in FIG. 12 (b), the total capacity of the game media 4 having the largest rarity value is ten. Therefore,
By selecting the winning game media using the deck 1-2, the game media 4 can be selected more than when the deck 1-1 (see FIG. 12 (a)) in which the total number of game media 4 is one is used. Is about 10 times easier to select. The expected value of the rarity value of the game media stored in the deck 1-2 may be the same as or different from the expected value of the rarity value of the game media stored in the deck 1-1. As described above, when the deck 1-1 and deck 1-2 shown in FIG. 12 are compared, the expected value of the rarity value is larger when the deck 1-2 is used (the deck 1-2 is better). The ratio of game media having a large rarity value is high), but the game media to be accommodated in the deck 1-2 can be determined so that the expected values of both are the same.

When the game is started by the player 1 in step 702 according to the flowchart shown in FIG. 13, the server device 10 causes the terminal device 30 to display a web page for generating a game medium acquisition request as shown in FIG. . FIG. 14 is an example of a web page display screen for prompting the game player to generate a game media acquisition request and send it to the server device 10, and unlike the diagram of FIG. 8, “normal lottery” and “ Two types of lottery “Premium Lottery” are displayed. For example, when the player 1 operates the terminal device 30 and selects the operation button 1402 represented as “request to obtain” displayed in association with the display of “normal lottery”, the terminal device 30 is connected to the deck 1- A game medium acquisition request including deck selection information indicating that 1 is used is generated, and the generated game medium acquisition request is transmitted to the server device 10. On the other hand, when the player 1 operates the terminal device 30 and selects the operation button 1404 represented as “request to obtain” displayed in association with the display of “premium lottery”, the terminal device 30 is connected to the deck 1- A game media acquisition request including deck selection information indicating that 2 is used is generated, and the generated game media acquisition request is transmitted to the server device 10. As described above, in the present embodiment, deck selection information indicating which deck 1-1 or deck 1-2 is to be used can be included in the game media acquisition request transmitted from the terminal device 30 of the player 1. .

In addition, the game media acquisition request may include the number of points such as game points consumed when acquiring the game media based on the game media acquisition request. For example, when the operation button 1402 is selected, a game medium acquisition request including the number of used points of 100 points is generated, and when the operation button 1404 is selected, the game medium including the number of used points of 300 points. An acquisition request is generated. For example, “normal lottery” may be requested for acquisition with in-game points given as the game progresses, and “premium lottery” may be requested for acquisition with virtual currency.

When the server device 10 acquires a game medium acquisition request including deck selection information from the terminal device 30 of the player 1, the process proceeds to step 1302. In step 1302, the winning game content selection unit 54 specifies a deck to be used for the winning game content selection process based on the deck selection information included in the acquired game content acquisition request. For example, when the deck selection information includes the deck identification information for identifying the deck 1-1, the deck 1-1 is specified as the deck that uses the deck 1-1. Subsequently, the process proceeds to step 706, and a winning game medium is selected from the game contents stored in the deck specified in step 1302, according to a predetermined lottery algorithm. After the winning game medium is selected, processing similar to the flow of FIG. 7 is performed.

  As described above, in the present embodiment, a plurality of decks having different types of stored game media and different numbers can be allocated to individual players. Thereby, each player can select a desired deck based on the type and the number of the game media stored.

Next, a server device according to another embodiment of the present invention will be described with reference to FIG. In the present embodiment, a single deck can be shared by a plurality of players. Based on the game media acquisition requests received from the two or more players, the winning game media is selected from the game media stored in the deck shared by those players. In this embodiment, a deck identification information management table shown in FIG. 15 is used instead of the deck identification information management table shown in FIG. The server apparatus according to the present embodiment has substantially the same configuration as that of the embodiment shown in FIGS. 1 to 10 except for the configuration of the deck identification information management table, except for processing that refers to the deck identification information management table. Performs substantially the same processing as that of the embodiment shown in FIGS. 1 to 10, and therefore, detailed description of portions common to those of the embodiment shown in FIGS. 1 to 10 is omitted.

  As shown in FIG. 15, the deck identification information management table in this embodiment stores deck identification information for identifying a deck assigned to the player in association with a plurality of player identification information. Can do. For example, in FIG. 15, deck identification information “D000001” is stored in association with player identification information “000001”, “000021”, and “000022”, respectively. Therefore, the winning game medium selection unit 54 is accommodated in the deck 1 identified by the deck identification information “D000001” when the game medium acquisition request is acquired from any one of the player 1, the player 21, or the player 22. The winning game media can be selected from the game media.

  Thus, in this embodiment, since one deck is shared by a plurality of players, it is possible to aim at acquisition of a game medium having a large rarity value in cooperation with a plurality of players.

  Next, a server apparatus according to another embodiment of the present invention will be described with reference to FIG. In the present embodiment, when a predetermined condition that can be set for each deck is satisfied, a new deck including more types of game media than the deck that has been used so far is used, Perform the selection process. A new deck containing more types of game media than an old deck may be referred to herein as an “expanded deck”. In addition, the “predetermined condition” set to determine whether or not to use the expansion deck may be referred to as “enlargement condition”.

In the present embodiment, the stored game content information management table of FIG. 16 is used instead of the stored game content information management table of FIG. The server device according to the present embodiment has substantially the same configuration as the embodiment shown in FIGS. 1 to 10 except for the configuration of the stored game content information management table, and refers to the stored game content information management table. Except for the processing, substantially the same processing as that of the embodiment shown in FIGS. 1 to 10 is performed, and therefore, detailed description of portions common to the embodiment shown in FIGS. 1 to 10 is omitted.

FIG. 16 shows an accommodation for storing accommodation game medium information related to a game medium contained in an expansion deck (enlargement deck 1) used in place of the deck 1 when the expansion condition is satisfied for the deck 1 shown in FIG. An example of a game media information management table is shown. Various conditions can be set as the enlargement conditions. For example, the same conditions as the initialization conditions described above can be used as the enlargement conditions. For example, when the same condition as the initialization condition (a) is used as the expansion condition, instead of deck 1 in response to the game medium having the highest rarity value being selected as the winning game medium in deck 1 Expansion deck 1 is set as the use deck. FIG. 16 shows an example of the expansion deck 1 that is set as a use deck when the initialization condition (a) is satisfied. Since the number of game media 4 contained in the deck 1 is 0, the game media 4 having the highest rarity value in the deck 1 is selected as the winning game media, and the initialization condition (a) is satisfied. This can be confirmed from FIG. After the expansion deck 1 is set as a use deck, the winning game medium selection unit 54 selects a winning game medium from the game contents accommodated in the expansion deck 1.

As shown in FIG. 16, the expanded deck 1 includes two types of game media that are not included in the deck 1 (the game media 7 identified by the game media identification information “M000007” and the game identification information “M000008”). The game media 8) identified by is stored. The rarity value and total capacity of game media added in the expansion deck 1 are not limited to those shown in FIG. Further, the number of types of game media to be added is not limited to the two types shown in FIG. 16, and may be one type or three or more types. In one aspect of the present embodiment, when the expansion condition is satisfied, a web page for generating and transmitting a setting request for setting the expansion deck as a use deck is transmitted from the server device 10 to the terminal device 30. May be. When the setting request generated based on the operation of the web page is acquired from the terminal device 30, the expansion deck can be set as the use deck.

  As described above, when the expansion condition is satisfied, the expansion deck is selected as the use deck, and after the expansion deck 1 is set as the use deck, the winning game medium is selected from the game media stored in the expansion deck 1. By selecting, it is possible to continue to attract the player's interest even after a game medium (for example, a rare card) having a large rarity value is selected or even when the number of game contents to be stored is reduced. Can do.

Although the present invention has been described above based on the most practical and desirable aspects at present, these descriptions are only for the purpose of explaining the present invention, and the present invention is not limited to the disclosed embodiments. It is not intended to be limiting. Rather, the description in this specification is intended to include modifications and equivalents included in the spirit and scope of the claims for any of the features of each embodiment described above. For example, combinations of the features of any of the above-described embodiments with one or more features of other embodiments are also included in the scope of the present invention as much as possible.

An example of a change to the above-described embodiment will be described. In one aspect of the present invention, as shown in FIG. 4, when one deck is assigned to each player, two types of game medium acquisition requests shown in FIG. 14 are sent to the terminal device 30 of the player. A web page for generating a game media acquisition request that can be generated may be transmitted. The game media acquisition request generated from this web page includes lottery type information indicating the type of lottery (that is, the type of lottery algorithm used by the winning game media selection unit 54). For example, the game medium acquisition request generated when the operation button 1402 is operated by the player includes lottery identification information indicating “normal lottery”, and is generated when the operation button 1404 is operated by the player. The game media acquisition request to be included includes lottery identification information indicating “premium lottery”. In the server device 10, when the game media acquisition request from the terminal device 30 is acquired, the winning game media selection unit 54 refers to the lottery type information included in the acquired game media acquisition request, and It is specified whether a type of lottery is required. When the lottery type information indicating “normal lottery” is included in the game media acquisition request, FIGS.
The same processing as in the embodiment shown in FIG. That is, a winning game medium is selected from the deck assigned to the player. On the other hand, when the game media acquisition request includes lottery type information indicating “premium lottery”, the winning game media is selected by a method in which a game media having a large rarity value is more easily selected. For example, a winning game medium can be selected at random from decks assigned to the player having a rarity value of 2 or more.

In this way, even when a single deck is used, two or more different algorithms can be selectively selected by including lottery type information for specifying different lottery methods in the game medium acquisition request acquired from the terminal device 30 of the player. Use to select the winning game media. In the above example, the expected value of the rarity value of the selected winning game medium is different between the case where the lottery algorithm corresponding to “normal lottery” is used and the case where the lottery algorithm equivalent to “premium lottery” is used. This corresponds to a difference in costs such as game points consumed by the player in each lottery method (see display regarding consumption points in FIG. 14).

  The processes and procedures described in the present specification are realized by software, hardware, or any combination thereof other than those explicitly described in the embodiments. More specifically, the processes and procedures described in this specification are performed by mounting logic corresponding to the processes on a medium such as an integrated circuit, a volatile memory, a nonvolatile memory, a magnetic disk, or an optical storage. Realized. Further, the processes and procedures described in the present specification can be implemented as various computer programs by implementing the processes and procedures as computer programs.

  Even if it is described that the processes and procedures described herein are performed by a single device, software, component, or module, such processes or procedures may involve multiple devices, multiple software, multiple Component and / or multiple modules. Also, even though the data, tables, or databases described herein are described as being stored in a single memory, such data, tables, or databases are provided on a single device. Alternatively, the data can be distributed and stored in a plurality of memories or a plurality of memories arranged in a plurality of devices. Furthermore, the software and hardware elements described herein can be implemented by integrating them into fewer components or by disassembling them into more components.

  In the present specification, when the constituent elements of the invention are described as either singular or plural, or even if they are described without being limited to singular or plural, they should be understood separately in context. The component may be either singular or plural.
