Abstract

Provided are a game control device, an item drawing method, an item drawing program, and a game system which enable the suppression of the possibility of newly acquiring an item that matches a game item already held by a player. A game server (20) selects any item from among a plurality of items that are the objects of a drawing according to a drawing operation corresponding to a player ID via a communication terminal (10). The game server (20) causes a database server (30) to associate and store the player ID and the selected item. When a predetermined condition corresponding to the player ID is satisfied, the game server (20) performs control such that the probability that an item matching the item associated with the player ID and stored by the database server (30) is selected becomes lower than the probability that this item is selected when the predetermined condition is not satisfied.

Description

Game control device, item lottery method, item lottery program, game system

The present invention relates to a technology for lottery processing of items in a game executed based on player identification information for uniquely identifying a player through communication from a communication terminal operated by the player.

Conventionally, for example, an item acquired by a player in a battle against a computer is exchanged for communication with an item held by another player. At this time, by randomly changing the appearance probability of the item for each game program purchased by the player, it is possible to avoid items held by a plurality of players from being the same, and to activate item exchange, etc. A technique aimed at achieving this is known (Patent Document 1).

By the way, in recent years, a so-called social game (executed by a game application created on the basis of an operating environment such as API (Application Programming Interface) operating on a web browser in a social networking service (SNS) by a specific service provider. Social Game) is popular. It can be said that the social game is a kind of online game that is played while communicating among an unspecified number of players. However, unlike a conventional online game, a social game does not play a game between players through a communication-equipped game device equipped with a game software, and the player installs or downloads the game software on the player side. There is no need. That is, if the player has a communication terminal equipped with a web browser, the player can execute a social game. Therefore, for example, if a portable terminal that can be connected to the Internet is provided, the player can enjoy a social game regardless of time and place. One of the features of the above-described social game is that it has a richer communication function for interaction between players than the conventional online game. In social games, for example, in addition to cooperative play with other players (companies), information exchange by communicating with friends such as greetings and contacts with friends, gifts of items on the game with friends or items An exchange has been made.

In the above social game, there may be an item lottery function that can randomly obtain items that can be used in the game. The content of the item depends on the type of social game, but in the case of a digital card game, for example, it is the card itself or a part of the card. The item lottery function includes a case where the player can execute the item lottery without charging the player (free lottery) and a case where the player can execute the item lottery on the condition that the player is substantially charged (paid lottery). is there. In the free lottery, it is set so that the possibility that a so-called rare item having a high rare value among items can be acquired is very low. On the other hand, in the pay lottery, the probability that a rare item can be acquired is set to be relatively high.

JP 2004-41561 A

By the way, in the above-described social game or conventional online game, there is a demand for players to acquire various types of items prepared according to the game. For example, when the social game is a digital card game in which a team is composed of a plurality of positions such as baseball and soccer, the player wants to obtain player cards (items) corresponding to player characters at various positions. There is a request. For example, in the case of a digital card game of a baseball game, there is a desire to obtain not only a player card corresponding to the 4th batter but also a player card corresponding to the 1st batter, and various types of pitchers throwing different ball types There is also a request to obtain a player card corresponding to. In addition, for players, the acquisition of player cards is part of the collection, and there is also a desire to have as many player cards as possible.

Here, when an item lottery is performed by pay lottery, if the item is selected at random, the same item as the item already owned by the player may appear. If the same item appears, the player will have two identical items, but this new item will not contribute to the change in the player's team organization, and will also benefit the collection. It is thought that there are few. If such a situation occurs, the player will not be able to obtain more profits than the free lottery despite the pay lottery, and will be dissatisfied. If such dissatisfaction occurs, the willingness to acquire a new item until the pay lottery is performed is lost, leading to a decrease in the appeal of the entire game.

The present invention has been made in view of the above-described viewpoints, and a game control device that can suppress the possibility of newly acquiring an item that matches an item on the game that the player already holds by lottery, An object is to provide an item lottery method, an item lottery program, and a game system.

A first aspect of the present invention is configured to be accessible by communication from a communication terminal operated by a player, and based on player identification information for uniquely identifying the player's game execution by the communication terminal. A game control device for controlling, comprising the following means.
(1) Item lottery means for selecting any item from among a plurality of items to be lottery in response to a lottery operation corresponding to player identification information by the communication terminal.
(2) Storage means for associating and storing the player identification information and at least the item selected by the item lottery means in the storage device.
(3) If a predetermined condition corresponding to the player identification information is satisfied, the probability that an item that matches the item stored in the storage device in association with the player identification information is selected satisfies the predetermined condition. Lottery control means for controlling the item lottery means so as to be lower than the probability that the item will be selected if not.

The game control device may be any information processing device that can establish a connection with each of the communication terminals of a large number or a large number of unspecified players via communication. Such a game control device may be, for example, one or a plurality of servers arranged on a network, or a large computer device. Further, the player and the communication terminal do not necessarily have a fixed one-to-one correspondence, and a usage mode of the communication terminal in which a plurality of players share a single communication terminal is also assumed. Therefore, this game control device manages a player for each piece of player identification information such as a player ID as information that can uniquely identify a player who plays a game.

Note that the game control device may be a stand-alone device (for example, a home game machine) that does not use the communication function. In that case, the following configuration may be provided.
Item lottery means for selecting any item from among a plurality of items to be lottery in response to a player's lottery operation.
Storage means for associating a player with an item selected by the item lottery means and storing it in a storage device.
When a predetermined condition according to the player is satisfied, the item is selected when the probability that an item that matches the item stored in the storage device in association with the player does not satisfy the predetermined condition is selected. Lottery control means for controlling the item lottery means so as to be lower than the probability of being played.

In this game control device, for example, an item held by the player corresponding to the player identification information is stored in the storage device. When the lottery control means satisfies a predetermined condition corresponding to the player identification information at the time of the lottery corresponding to the player identification information, the lottery control means refers to the item stored in the player corresponding to the player identification information. The probability of selecting an item that matches is relatively low. Therefore, the possibility that the player can acquire an item different from the item already owned by the lottery increases. For example, in the case of a digital card game of a game in which a team is composed of a plurality of positions such as baseball and soccer, the player can advantageously advance the game by obtaining player cards corresponding to various player characters as items. The above-described configuration is particularly preferable. In addition, since it is difficult for the player card already possessed to match the newly acquired player card (because it is less likely to be confused with the player card possessed by the player), the player has a variety of his / her own collection. There is also an advantage that it is easy to increase player cards. In addition to satisfying the value for the player's lottery operation, the predetermined condition may be that the time when the player performs the lottery operation is between a predetermined time and a predetermined time in the real world or in the game ( For example, in the real world between 8 am and 8:15 am). Further, the time at which the player performs the lottery operation may be between a time point when the skill level of the player on the game reaches a predetermined level and a predetermined period (for example, half a day or 6 hours).

The game control device may further include the following features.
(4) The predetermined condition is that a payment amount of the player on the game, a consumption amount of economic value, or a consumption amount of points available to the player on the game as a consideration for the lottery operation based on the player identification information , At least one of them is a predetermined value.

The game control device is particularly suitable when the predetermined condition corresponding to the player identification information requests the player for a predetermined price as described above. This is due to the following reason. If the item lottery does not request a price from the player (for example, in the case of a free lottery), even if the same item as the item already held by the player appears by the lottery, it is strong against the player because it is a free lottery. It is thought that no complaints will occur. However, when a predetermined value is requested from the player at the time of the lottery (for example, in the case of a pay lottery), the same item as the item already held by the player appears despite the fact that the corner pay lottery has been performed. As a result, it is expected that the player will have a strong dissatisfaction. Therefore, by executing the lottery control means under the condition for requesting a predetermined price for the player, it is possible to suppress dissatisfaction with the lottery result by pay lottery, for example. As a result, the player can be conscious of acquiring an item by, for example, a pay lottery, and the attractiveness as a game can be maintained.
In addition, by setting the predetermined condition as described above, it can be set to leave the player whether or not the predetermined condition is satisfied. In other words, whether the player makes a free lottery or a paid lottery, and whether to make a paid lottery, whether or not to flexibly control the probability while referring to the payable amount or the acquisition points at the time of the lottery operation. This makes it possible to decide whether or not, so that the degree of freedom as a game increases and the range of games can be expanded.

The game control device may further include the following features.
(5) The lottery control means is an item that matches the item selected by the item lottery means during a predetermined period in the past, or in a predetermined number of lottery operations in the past, based on the time when the lottery operation was performed. The probability that the item is selected is lower than the probability that the item is selected when the predetermined condition is not satisfied.

In the game control device having the configuration of (1) to (3) or (1) to (4), a player who has not played much time since starting the game and a player who has already played a game for a long time There may be unfairness between In other words, a player who has not passed much time since the start of the game has a small number of items already acquired, and therefore has few types of items, and therefore satisfies a predetermined condition corresponding to the player identification information. Regardless of whether or not the item obtained by the new lottery is unlikely to match the item already held.
Therefore, the condition that the item obtained by the item lottery means of the game control device having the configuration of (1) to (3) or (1) to (4) is difficult to match the item already owned by the player. Therefore, an item with a relatively high appearance probability (that is, a normal item that is not a so-called rare item with a high rarity value) is likely to be selected. In the first place, the appearance probability of rare items is often set low, and if it is a normal item that is not a rare item, there is a high possibility that the condition that it will be difficult for the player to match the item already held is satisfied. . On the other hand, a player who has already played a game for a long time is considered to have already held a variety of normal items, so when trying to satisfy the condition that it becomes difficult for the player to match the items already held by the player There is a high possibility that a rare item having a low appearance probability is selected. Therefore, if the predetermined conditions in the lottery control means are substantially the same for a player who has not played much time since the game started and a player who has already played the game for a long time, The chances of rare items appearing in the lottery are different and can be unfair.
Therefore, in the lottery control means, the item for which the above-described probability is controlled is determined based on the time when a new lottery operation is performed among the items held by the player, or a predetermined number of times in the past. It is preferable to limit to items acquired (that is, selected) in the lottery operation. This makes it unlikely that a difference in the probability that a rare item will appear between a player who has not played much time since the game started and a player who has already played the game for a long time. Fairness can be ensured.

The game control device may further include the following features.
(6) The lottery control means, as a consideration for the lottery operation based on the player identification information, pays the player on the game, consumes the economic value, or consumes the points available to the player on the game The larger the at least one of, the longer the predetermined period or the predetermined number of times.

In this game control device, the predetermined period is increased as the amount of consideration is increased, or the predetermined number of times is increased. Thereby, the player can adjust himself / herself the probability that the item obtained by the new lottery does not match the item already held. That is, it is possible to increase the possibility of acquiring an item that is not held. Thereby, it becomes possible to set the playability of a game flexibly.

The game control device may further include the following features.
(7) In the item lottery means, the probability that a specific first item among the plurality of items is selected is lower than the probability that a second item other than the first item is selected. The probability that each of the plurality of items is selected is set in advance.
(8) The lottery control unit satisfies the predetermined condition corresponding to the player identification information and includes the first item as an item stored in the storage unit in association with the player identification information. The probability that the first item is selected is not lower than the probability set in advance for the first item.

In this game control device, for example, the second item is a normal item that is relatively likely to appear (that is, easy to select), and the first item is a rare item that is difficult to appear (that is, difficult to select). Good. At this time, if the player already has the first item (rare item), the lottery control means does not lower the probability that the same rare item appears due to a new lottery. The reason is that even if the player has two or more identical rare items, the player presents the same rare item with a plurality of pieces to other players, exchanges with items held by other players, or This is because possessing two or more rare items may not necessarily be a disadvantage to the player because various disposal methods such as selling to other players can be adopted. In other words, the rare item may have two or more of the same items, or may be configured in consideration of a player who wants to hold two or more.

A second aspect of the present invention is configured to be accessible by communication from a communication terminal operated by a player, and based on player identification information for uniquely identifying the player to execute the game of the player by the communication terminal. An item lottery method in a game control device to be controlled, comprising the following steps.
(9) A step of storing the player identification information and the item on the game in association with each other in the storage device.
(10) The probability that each item is selected when selecting any item from a plurality of items available on the game in response to a lottery operation based on specific player identification information by the communication terminal. Presetting.
(11) When a predetermined condition corresponding to the player identification information is satisfied, the probability that an item that matches the item stored in the storage device in association with the player identification information is selected satisfies the predetermined condition. A step of controlling to lower the probability that the item is selected if not.

The item lottery method may include the following configuration.
The step of associating the player identification information with the item on the game and storing it in the storage device.
A step of presetting a probability that each item is selected when selecting any item from a plurality of items available on the game in accordance with a lottery operation based on specific player identification information.
When the predetermined condition corresponding to the player identification information is satisfied, the probability that an item matching the item stored in the storage device in association with the player identification information is selected does not satisfy the predetermined condition Controlling to lower the probability that the item is selected.

According to a third aspect of the present invention, there is provided a computer for lottery of items in a game executed in units of player identification information for uniquely identifying a player via a network from a communication terminal operated by the player. It is a program for functioning as means.
(12) Item lottery means for selecting any item from among a plurality of items to be a lottery according to the lottery operation corresponding to the player identification information by the communication terminal.
(13) Storage means for associating the player identification information with at least the item selected by the item lottery means and storing it in the storage device.
(14) When a predetermined condition corresponding to the player identification information is satisfied, a probability that an item matching the item stored in the storage device in association with the player identification information is selected satisfies the predetermined condition. Lottery control means for controlling the item lottery means so as to be lower than the probability that the item will be selected if not.

The computer is, for example, a network server or a large computer. The game program may be stored in a computer-readable information storage medium such as a DVD-ROM or CD-ROM.

According to a fourth aspect of the present invention, there is provided a communication terminal operated by a player and a player accessible by communication from the communication terminal, and a player for uniquely identifying a player's game execution by the communication terminal.

As shown in FIG. 3, the game server 20 includes a CPU 21, a ROM 22, a RAM 23, a database (DB) access unit 24, and a wireless communication interface unit 25, for transmitting control signals or data signals between the units. Bus 26 is provided. In addition, the game server 20 can take the same structure as a general-purpose web server regarding hardware.

The ROM 22 stores an application program that provides a service for displaying an object such as an HTML document or an image (displaying a web page) to the web browser of the communication terminal 10 that is a client. The ROM 22 stores various data referred to by the CPU 21 in addition to the application program.
The CPU 21 loads the game program in the ROM 22 to the RAM 23 and executes it, and performs various processes via the wireless communication interface unit 25.

For example, the CPU 21 transmits HTML data to the communication terminal 10 via the wireless communication interface unit 25. In addition, when the game server 20 performs the authentication process of the player of the communication terminal 10, the CPU 21 performs the authentication process.
The CPU 21 performs processing according to the hyperlink or menu selected by the player on the web page displayed on the communication terminal 10 via the communication interface unit. The processing includes, for example, transmission of new HTML data, arithmetic processing in the game server 20 or data processing.
The database access unit 24 is an interface when the CPU 21 reads / writes data from / to the database server 30.

(3-1) Example of Game Realized by Game Server The type of game realized by the game server 20 of the present embodiment is not particularly limited, but in the following, for convenience of description of the embodiment, the game server A digital card game is taken up as an example of a game realized by 20.
For example, in a digital card game in a soccer format, a player collects player cards corresponding to soccer players (player characters to be described later) to create his / her team and play soccer against other players' teams alone, or skills It is a game that is configured to fight soccer league battles for each level. In soccer-style digital card games, a scout function that searches for player cards to create your own team, a lottery function that allows you to obtain player cards by lottery, or a combination of two player cards In addition, a strengthening function is provided to level up any player card.

The lottery function is preferably executed through an effect of taking out (drawing) one player card from the lottery box. The player cards that appear by lottery are basically random, but the probability that a player card (so-called rare card) of a player with outstanding technical ability or a popular player will appear in the lottery is set very low. As will be described later, the lottery function includes a “lottery by ale points” in which a player card is drawn in exchange for a predetermined amount of ale points, and a lottery that is advantageous to the player by substantially charging the player “a lottery by coins” "

Items prepared in the soccer-style digital card game that the player holds on the game include puzzle cards in addition to player cards. Pieces of the puzzle card can be obtained by the scout function, and are composed of a predetermined number (for example, six pieces) of different symbol pieces. By obtaining all the pieces of the symbols constituting the puzzle card, the player can exchange it for one powerful player card.
In this soccer-style digital card game, a battle mode between players is prepared for the purpose of catching pieces of puzzle cards from the opponent. In this battle mode, a certain player can execute a battle with another player for the purpose of obtaining a piece of the desired symbol, and if he wins the opponent, he can take away the desired symbol piece from the opponent.

In this soccer-type digital card game, an operating cost is set, which is a cost that is successively consumed (that is, reduced) by the game activity by the player. Is now restricted. Since the operation cost is recovered by a predetermined cost during a predetermined time, the player waits without executing the game when the operation cost is reduced.

In this soccer-type digital card game, a match result between players is determined by the game server 20 and immediately displayed on the communication terminal 10, and a complicated button operation on the communication terminal on the player side is unnecessary. It is suitable as a game.
In this soccer-type digital card game, the player can register his / her friends as will be described later. Any number of friends can be registered. Network services are provided that allow exchanges on the network, such as message exchanges, game item presents or item exchanges, and sending (cheering) ale to other players. The Players can obtain a certain amount of Yale points by sending Yale to fellow players, and can perform “Lottery with Yale Points” as a free lottery to draw a player card in exchange for a predetermined amount of Yale Points It is configured as follows.

This soccer-style digital card game is provided with a function that is substantially realized by charging the player (hereinafter referred to as “paid function”). An example of such a function is, for example, “coin lottery”. Here, the “coin” is a virtual currency that can be obtained on a game and can be obtained by paying money in advance to a service provider who provides the digital card game on a network by a method such as payment by a credit card. It is. The “coin lottery” has a higher probability of a rare card appearing in the lottery than the free lottery “ale point lottery”, or a player card already held by the player as will be described later. There is an advantage that the probability of drawing the same player card in a lottery is reduced.

(4) Configuration of Database Server The database server 30 can be realized by a general-purpose storage such as a large-capacity hard disk device or a device such as RAID (Redundant Arrays of Inexpensive Disks). Each database in the database server 30 is configured to be able to read and write data from the CPU 21 via the database access unit 24 of the game server 20.
FIG. 4 shows an example of the configuration of the database server 30. As shown in FIG. 4, the database server 30 includes a player database 31 and a game result database 32.

FIG. 5 shows an example of the player database 31 applied in the above-described soccer-style digital card game. In this example, the player database 31 stores, for each player ID (player identification information), display name / display image, skill level, operating cost, ale point, possessed coin, friend, owned item, and character data. Contains information. Information included in the player database 31 can be sequentially updated by the game server 20.

In the following description, the player ID included in the player database 31 or the data for each display name (to be described later) specifying the player is generically referred to as “player data”. The data of each item constituting the player data is as follows.
The “display name / display image” is a display name and a display image that are displayed to identify the player on the communication terminal 10 when the game is executed. The display name is text of a predetermined length or less specified in advance by the player, and the display image is, for example, an avatar image selected in advance by the player. The display name is a name that identifies the player on the network environment (or game community) provided by the game server 20.
“Skill level” means a skill level of a player on the game, and is a level value in a range from Lv1 (level 1) to Lv10 (level 10), for example.
The “operation cost” is a cost necessary for performing the game activity by the player corresponding to the player ID in the above-described soccer-type digital card game. The operating cost is a value that is reduced by an activity on the game such as a battle with another player and recovered (increased) over time. The unit of “operating cost” is P (points).
“Ale points” are points acquired by the player based on the ale function of the above-described soccer-style digital card game.
The “owned coin” is a possessed amount of virtual currency (coins) on the game that is required when the player corresponding to the player ID uses the pay function on the game. The possessed coins are consumed (reduced) when the player uses a pay function on the game, and the player pays actual money to the service provider or the like by a predetermined method, and increases according to the amount paid.
“Friend” is data of another player ID that is a friend of the target player ID.
In the case of the above-described soccer-style digital card game, the “held item” is data including images of player cards and puzzle card pieces held by the player corresponding to the target player ID.

“Character data” includes player character information about the game. The player character may include various types of information depending on the nature of the game. For example, in the case of a soccer-style digital card game, the player character means a player on the game corresponding one-to-one with the player card. The player character information is information in which the ability value (ability parameter) of the player character (player) is described for each item. For example, as shown in FIG. 5, each ability value such as “running ability”, “kicking ability”, “defense ability”, and the like may be included as items. When the player acquires the player ID, the character data includes predetermined default data.

Returning to FIG. 4, the game result database 32 stores and updates information related to the game result executed by the game server 20 based on the access from the game server 20. Information related to game results may include various information depending on the nature of the game. For example, in the case of a soccer-style digital card game, information on game results includes results of battles between different player IDs (scores, etc.), results of league battles between a plurality of player IDs of specific skill levels ( Score, ranking, etc.).

(5) Overview of Functions in Game Control Device In the present embodiment, the game control device is configured by the game server 20 and the database server 30. Below, the function implement | achieved with the game control apparatus of this embodiment is demonstrated with reference to FIG. 6, taking the case where the digital card game of the soccer format mentioned above is applied as an example. FIG. 6 is a functional block diagram for explaining functions that play a main role in the game control apparatus of the present embodiment. In the functional block diagram of FIG. 6, the registration means 51, the battle execution means 53, and the skill level management means 542 of the player data management means 54 are not essential to the present invention. However, in carrying out the present invention. This is a preferred configuration.

The registration means 51 has a function of recognizing a player's request based on an appropriate operation input to the communication terminal 10 on a web page provided to the communication terminal 10, for example, and performing a registration process. The function of the registration means 51 in this case is realized as follows, for example. The CPU 21 of the game server 20 receives a registration request message from the communication terminal 10 via the wireless communication interface unit 25. The registration request message is automatically generated by a predetermined operation (for example, a predetermined menu selection operation, text input, etc.) on the communication terminal 10 on the web page provided from the game server 20. May be configured. The registration request message may include information (for example, an IP address, an email address, etc.) for specifying the communication terminal 10 that is the transmission source, or the player has already played another game by the same service provider. If used, the player ID may be included.
When the CPU 21 receives the registration request message and does not include a player ID in the registration request message, the CPU 21 issues a new player ID and performs registration processing of the player ID, and then the registration processing is completed. Is sent to the communication terminal 10. When the CPU 21 receives the registration request message and includes a player ID in the registration request message, the CPU 21 performs registration processing of the player ID, and then transmits a registration completion message indicating that the registration processing is completed. 10 to send.
When the registration is completed, the CPU 21 determines a player for a new player ID in which predetermined default data (the specified initial value is described as character data without any friends or possessed items at the time of registration). Data is stored in the player database 31.

The registration means 51 may also have a function of registering the player ID in association with another player ID triggered by an application based on the player ID. That is, the registration unit 51 registers another player ID as a “mate” with an application based on the player ID as a trigger. In the following description, it is synonymous that the player ID has a friend relationship and that the corresponding player has a friend relationship.
The function of the registration means 51 in this case is realized as follows, for example. The CPU 21 of the game server 20 applies an application message (application) specifying a player ID (or a corresponding display name) to be a friend from the communication terminal 10 of the player corresponding to a certain player ID via the wireless communication interface unit 25. Accept. The transmission of the application message is set in advance as a function of a web page provided to the communication terminal 10 of the player. When receiving the application message, the CPU 21 approves an application based on another player ID to the communication terminal 10 corresponding to the player ID at the timing when there is an access based on the player ID included in the application message. HTML data for displaying a web page for requesting the reply is transmitted. If it is replied that the application is approved, the CPU 21 registers both as friends. Specifically, the CPU 21 writes data in the “mate” portion (see FIG. 5) of the player data of the corresponding two player IDs in the player database 31.

The game progression means 52 has a function of advancing a game displayed on the player's communication terminal 10 through a web page on the communication terminal 10 in response to an operation on the communication terminal 10 by the player.
The function of the game progress means 52 is implement | achieved as follows. The CPU 21 of the game server 20 transmits HTML data for displaying a web page corresponding to a hyperlink or menu selection on the web page by the player to the communication terminal 10 via the wireless communication interface unit 25. The CPU 21 sequentially transmits new HTML data in accordance with the selection of a hyperlink or menu on the web page by the player, whereby the web page displayed on the communication terminal 10 is sequentially switched, so that the player progresses the game. Recognize
Further, in the game progress means 51, when the CPU 21 of the game server 20 receives an access request message from the communication terminal 10 via the wireless communication interface unit 25 prior to the start of the game, the communication is performed after a predetermined authentication process. The player ID included in the access request message is recognized from the terminal 10. Then, the CPU 21 manages the progress of the game displayed on each communication terminal 10 in units of player IDs.

FIG. 7 shows an example of the display on the communication terminal 10 of the player executed by the game progress means 52, and shows the top page in the soccer-style digital card game. The top page is composed of web pages corresponding to individual player IDs. The top page illustrated in FIG. 7 includes a player data display area, a player image display area, and a basic menu display area. The player data display area is obtained as a result of the CPU 21 reading out the data of each item of the skill level, the operation cost, the yell point, the player card, and the mate included in the player data of the target player ID (see FIG. 5). This is the area to be displayed. The player image display area corresponds to a player card at a predetermined position included in the player data of the target player ID (for example, a player card of a player character corresponding to an ace striker, or a player character first ordered in the player data) This is an area displayed as a result of the CPU 21 reading out the image data of the player card. The basic menu display area includes “Scout”, “Position”, “Position” as basic menus corresponding to multiple functions (scout function, position function, strengthening function, lottery function, battle function) provided in the soccer card game. This is an area where menus of “enhancement”, “lottery”, and “game” are arranged. In the game progress means 52, the CPU 21 receives the basic menu selection operation for the communication terminal 10 by the player, and transmits the HTML data for displaying a new web page corresponding to the selected menu to the wireless communication interface unit 25. To the communication terminal 10. In the new web page, a menu for instructing more specific game execution contents for the function corresponding to the selected basic menu is prepared.

The menu selection operation in the communication terminal 10 may be, for example, an operation of pressing (ie, clicking) the decision button after operating the direction instruction button of the operation input unit 15 to select a desired menu. When the operation input unit 15 accepts an input of a selection operation, the wireless communication interface unit 17 of the communication terminal 10 transmits a signal (message) including a menu selection result to the game server 20.

The process for progressing the game performed in the game progress means 52 can be arbitrarily set depending on the nature of the game. However, in the case of the above-described soccer-type digital card game, the player performs hyper-processing on the web page. A process of executing at least one of a plurality of functions (a scout function, a position function, an enhancement function, a lottery function, and a battle function) according to the selection of the link or menu is included. The battle function is substantially performed by the battle execution means 53 described later. The scout function, the enhancement function, and the lottery function have already been described, and the following description does not refer to each function. The position function is a function for executing a replacement of the position of the player character, a replacement with a reserved player character, or the like under the instruction of the player.

As shown in FIG. 6, the game progress means 52 includes an item lottery means 521 and a lottery control means 522. The item lottery means 521 and the lottery control means 522 can be executed in cooperation when the “lottery” menu is selected (that is, a lottery operation is performed).

The item lottery means 521 has a function of selecting any player card from a plurality of player cards (items) to be selected in accordance with a lottery operation corresponding to the player ID by the communication terminal 10. Various methods can be used for selecting a player card. For example, a method of selecting one player card at random from each of a plurality of player cards to be drawn can be adopted. In this method, the probability (appearance probability) that each player card is selected is substantially the same. Further, it is possible to adopt a method in which an appearance probability or a range of appearance probabilities is determined in advance for each of a plurality of player cards to be selected, and one player card is selected according to the appearance probability. This method is an effective method for setting a rare card on a game because a player card that is likely to appear and a player card that is unlikely to appear can be determined in advance among a plurality of player cards to be drawn.

The function of the item lottery means 521 is realized as follows. The CPU 21 of the game server 20 receives the first signal indicating that the lottery operation associated with the specific player ID has been input from the communication terminal 10, so that the lottery operation corresponding to the player ID is performed. Recognize what happened. And CPU21 performs the process which selects one player card from the several player card used as the lottery object decided beforehand. At this time, when the appearance probability or the range of the appearance probability is determined in advance for each of the plurality of player cards to be drawn, the appearance probability data for each player card is stored in the ROM 22. Then, the CPU 21 executes a player card selection process based on the appearance probability data read from the ROM 22.

The item lottery means 521 further has a function of causing the player's communication terminal 10 to execute a display for guiding the player's lottery operation and / or a display for notifying the player of the lottery result. In order to realize this function, the CPU 21 of the game server 20 transmits HTML data (second signal) for performing the above display to the communication terminal 10 via the wireless communication interface unit 25. The communication terminal 10 receives this HTML data via the wireless communication interface unit 17.

FIG. 8 is an example of a display for guiding the player's lottery operation. The display example of FIG. 8 shows a display example after the player performs a “lottery” menu selection operation in the display example of FIG. Here, the player is presented with two lottery menus: “lottery by ale points” which is a free lottery and “lottery by coins” which is substantially a pay lottery. The “coin lottery”, which is a paid lottery, has the advantage that the player card is less likely to appear in the same player card as the player card that the player already holds compared to the “ale point lottery”. Presented.

9A to 9C are examples of displays for notifying the player of the lottery result. The display examples of FIGS. 9A to 9C sequentially show display examples presented to the player in the display example of FIG. 8, for example, when the player selects the menu “Lottery” for “Lottery with Yale Points”. Is. The display examples of FIGS. 9A to 9C are examples in which the player card drawn by the player as a result of the lottery is produced so as to jump out of the envelope. When recognizing that the player has selected the “Lottery” menu for “Lottery with Yale Points”, the CPU 21 executes the lottery in a very short time and notifies the communication terminal 10 of the lottery result. However, since displaying the lottery result immediately after the player selects the “Lottery” menu is not very interesting for the game, it is preferable to perform the effect display shown in FIGS. 9A to 9C. Specifically, in FIG. 9A, an envelope including one player card drawn by the player from the box is displayed. In FIG. 9B, the envelope shown in FIG. 9A is opened, and the player card (player card selected by lottery) is displayed upward from the envelope. In FIG. 9C, the entire player card appearing from the envelope is displayed, and a text such as “Get ABC player card!” Is also displayed. By performing such an effect display, it is possible to realize a player's simulated experience that the player has drawn the player card from the box through the display screen of the communication terminal 10.

When the lottery control means 522 satisfies a predetermined condition corresponding to the player ID, the lottery control means 522 matches the player card stored in the player database 31 in association with the player ID (that is, the player card already held by the player). A function for controlling the item lottery means 521 is provided so that the probability that the player card to be selected is lower than the probability that the player card is selected when the predetermined condition is not satisfied. Here, the “predetermined condition corresponding to the player ID” may be arbitrarily set, but as a consideration for the lottery operation based on the player ID, the payment amount of the player on the game, the consumption amount of the economic value, or the game The condition that at least one of the points consumed by the player is a predetermined value is preferable.

In the example shown in FIG. 8, the function of the lottery control means 522 is executed by selecting the menu “Lottery” for “lottery with coins” corresponding to the pay lottery. in this case,
The “predetermined condition corresponding to the player ID” corresponds to a condition that the coin paid by the player is 300 coins (predetermined value), but it goes without saying that the predetermined value of the coin amount can be arbitrarily set. In addition, here, the condition is that a predetermined amount of virtual currency that can be used on a game called coins is paid, but it may be a condition that a predetermined amount of actual money is paid directly through a predetermined procedure. . Moreover, although it is good also as conditions on consuming a predetermined amount of an ale point, the amount of the ale point consumed in this case is from the amount (200P in the example of FIG. 8) set by "the lottery by an ale point". Is also considerably large (for example, 500 P).
In FIG. 8, “lottery by ale points” corresponding to free lottery is an example of a lottery that does not satisfy “predetermined conditions corresponding to player ID” because the player can draw lots without paying coins.

The function of the lottery control means 522 is realized as follows. When the CPU 21 of the game server 20 recognizes that the menu “Lottery” has been selected for “Lottery with coins”, the appearance probability or appearance probability of each of the plurality of player cards to be drawn is read from the ROM 22. Data indicating the range (data of appearance probability) is read. Further, the CPU 21 accesses the player database 31 and reads out a player card already held by the player with the player ID corresponding to the lottery operation. Next, the CPU 21 selects the player card when the probability that the player card that matches the player card held by the player is selected as the data of the appearance probability read from the ROM 22 is “lottery by an ale point”. Change to be lower than the probability. In this case, the item lottery unit 521 described above executes a lottery process (player card selection process) based on the appearance probability data changed by the lottery control unit 522.

Hereinafter, an example of changing the appearance probability data will be specifically described with reference to FIGS. 10 and 11.
10 and 11 both show an example of data on the appearance probability of a player card in a lottery. FIG. 10 shows data before the change in appearance probability, and FIG. 11 shows data after the change in appearance probability. For example, FIG. 10 shows data of appearance probabilities referred to in “lottery by ale points”, and FIG. 11 shows data of appearance probabilities referenced in “lottery by coins”. Note that, as illustrated in FIG. 5, this example is a modification example in the case where the player with the player ID corresponding to the lottery operation already has a player card “PL001”.

As shown in FIG. 10, the player cards "PL001", "PL002", and "PL004" are normal cards (normal items), and the appearance probability range (0.2 to 0.3) is set to be relatively high. ing. On the other hand, the player card of “PL003” is a rare card, and the appearance probability range (0.01 to 0.05) is set low. Each time the lottery process is performed, the appearance probability of each player card may be randomly determined within the range of the set appearance probability. Here, since the player with the player ID corresponding to the lottery operation already has a player card of “PL001”, the appearance probability of the player card of “PL001” in the data of the appearance probability after change shown in FIG. Reduced (0.2-0.3 → 0.05-0.1). This makes it difficult for the player card “PL001” already owned by the player to appear by lottery. As shown in FIG. 11, the appearance probability of other normal cards not owned by the player may be relatively increased according to the decrease in the appearance probability of the player card “PL001” (0. 2 to 0.3 → 0.25 to 0.35).

The battle execution means 53 has a function of executing a battle between players corresponding to the player ID so that an item held by the defeated player is transferred to the winning player. In the following description, “a battle between players” is synonymous with “a battle between player characters” which means a battle between player characters corresponding to player cards held by the player.

The function of the battle execution means 53 is realized as follows, for example. When the selection operation of the “game” menu is performed on the top page of the communication terminal 10 of the player corresponding to a certain player ID and the selection result is received, the CPU 21 of the game server 20 selects the opponent of the player ID as the player. Randomly determined from other player IDs included in the database 31. At this time, it is preferable that the skill levels of the player IDs that compete are the same.
When the opponent is determined, the CPU 21 transmits HTML data for displaying a web page for notifying the opponent to the communication terminal 10. In executing the battle, the CPU 21 accesses the player database 31 of the database server 30 via the database access unit 24, and reads out the character data associated with the two player IDs as opponents. And CPU21 performs the battle | competition between player characters based on the read character data.

The determination method of winning or losing the battle can be any method as long as the ability value of the player character affects the winning or losing. For example, the ability values of the player characters associated with the two player IDs that are opponents are compared, and a player character with a larger ability value has a higher probability (for example, a predetermined probability within a range of 60 to 90%). You may set it to win. The win rate may be higher as the difference in ability values is larger. At this time, as shown in FIG. 5, when there are a plurality of ability value items, predetermined weighting (for example, in the example of FIG. 5, “running force” is 0.3 and “kicking force” is 0. .3, “defense power” is set to a weight of 0.4, etc.), and a comprehensive ability value can be calculated and used as a comparison target.

When the CPU 21 determines the battle result of the battle of the player character associated with the two player IDs as the opponents, the CPU 21 displays HTML data for displaying a web page including the battle results as the two player IDs of the opponents. To the player's communication terminal 10. Then, the communication terminal 10 interprets the HTML data received from the game server 20 and displays an image including the battle result on the display unit 16. After determining the battle result, the CPU 21 performs a process of writing details of the battle result in the game result database 32 via the database access unit 24.
Since the time from when the player selects the “game” menu on the top page illustrated in FIG. 7 until the web page including the match result is displayed is extremely short (for example, several seconds). The player can know the battle result in a very short period of time only with a simple operation.

The player data management means 54 is a function for updating the player data in the player database 31 and includes an item storage means 541 and a skill level management means 542.
The item storage unit 541 has a function of associating and storing in the player database 31 a player ID and an item that the player corresponding to the player ID holds in the game. The function of the item storage unit 541 is realized as follows, for example. The CPU 21 of the game server 20 accesses the player database 31 and stores and updates items (for example, player cards, pieces of puzzle cards) that the player corresponding to the player ID holds in the game. For example, when the player data management means 54 stores or updates the item, for example, when the player obtains a new player card on the game, or a predetermined number of pieces of puzzle cards obtained by the player are used as one player card. For example, when converting.

The skill level management means 542 has a function of managing each player ID so as to belong to one of a plurality of skill levels on the game. The skill level management means 542 classifies the player ID into one of a plurality of skill levels according to the progress of the game of the player or the increase of the ability value of the player character of the player. For example, the skill level management means 542 sets the skill level to Lv1 at the start of the game, and increases the skill level as the player character's ability value increases.
The function of the skill level management means 542 is realized as follows, for example. The ability value data of the player character (that is, character data; see FIG. 5) can be updated by, for example, the strengthening function, but the CPU 21 of the game server 20 refers to the ability value and compares it with a predetermined threshold value. Then, it is determined whether or not to increase the skill level of the corresponding player ID. When increasing the skill level, the CPU 21 updates the skill level item included in the player data of the corresponding player ID.

The player data management means 54 has a function of managing operating costs, ale points and possessed coins included in the player data. Management of operating costs, ale points and owned coins includes updating the operating costs, ale points and owned coins for each player ID.
The function of this player data management means 54 is implement | achieved as follows, for example. It is assumed that the maximum value of the operating cost given to the player ID is a fixed value. Then, when the CPU 21 of the game server 20 consumes the cost for the activity (or execution) of the game for a specific player ID, the CPU 21 accesses the player database 31 and operates the player data of the player ID. Is updated so as to reduce the amount of cost consumed. Here, it is assumed that the relationship between each activity on the game and the cost to be consumed (hereinafter referred to as consumption cost) is known. For example, a database describing the relationship between individual activities on the game and consumption costs is stored in the ROM 22, and the CPU 21 may refer to the database in the ROM 22 when calculating the cost. Further, the CPU 21 recovers (that is, increases) the value of the operation cost of the player ID by a predetermined amount (for example, 1P per minute) in a predetermined time.
Further, the CPU 21 sequentially monitors the operation cost of the player data, and restricts new activities on the game when the remaining operation cost is low. For example, when the value of the operation cost is smaller than the cost of consumption due to the battle, the player cannot perform a new battle and needs to wait for the battle to be performed until the management cost is sufficiently recovered.

In addition, when a specific player obtains an ale point or when an ale point is consumed by drawing a player card by “a lottery by an ale point”, the CPU 21 accesses the player database 31 to correspond to the corresponding player. The ale point of the player data of ID is updated. Further, when executing a pay function that requires coin consumption (for example, “the lottery with coins” described above), the CPU 21 accesses the player database 31 to obtain coins possessed by the player data of the corresponding player ID. Update (reduce).

(6) Flow of main processes of game control apparatus of this embodiment Next, an example of the flow of the main processes performed by the game control apparatus of this embodiment is demonstrated with reference to the flowchart of FIG. FIG. 12 is a flowchart showing a lottery process performed in response to a menu selection operation by the player. A series of processes shown in FIG. 12 is mainly executed by the item lottery means 521 and the lottery control means 522 of the game server 20.

First, as illustrated in FIG. 7, when the selection operation of the “lottery” menu is performed in the display state where the communication terminal 10 displays the top page (step S <b> 10: YES), the player of the player who performed the selection operation The game server 20 receives a signal (first signal) including the ID and the selection result. In response to the reception of the first signal, the game server 20 determines whether to select either “free lottery by an ale point” which is a free lottery or “lottery by a coin” which is substantially a pay lottery. HTML data for performing display (see FIG. 8) for guiding the operation is transmitted. In FIG. 8, when “lottery by ale points” is selected (step S20: NO), the processing of steps S30 to S50 is not performed. In FIG. 8, when “coin lottery” is selected (step S20: YES), the player data management means 54 updates (decreases) the possessed coins of the player data of the corresponding player ID, and the owned coins settlement process. Is performed (step S30). When this settlement process is appropriately performed, it may be considered that the lottery control unit 522 satisfies a predetermined condition for executing the lottery control. The lottery control means 522 refers to the player database 31 and searches for a player card already held by the player with the player ID corresponding to the lottery operation (step S40). Furthermore, the lottery control means 522 reads out the appearance probability data from the ROM 22, and the probability that the player card that matches the search result (player card held by the player) in step S40 is selected is reduced. Change (step S50).

Subsequently, the item lottery means 521 executes a lottery process (player card selection process) based on the appearance probability data changed by the lottery control means 522 (step S60). Furthermore, the item lottery means 521 transmits, for example, HTML data for effect display shown in FIGS. 9A to 9C to the communication terminal 10 corresponding to the player ID (step S70). When “lottery by ale points” is selected (step S20: NO), the lottery process in step S60 is performed with reference to the appearance probability data read from the ROM 22 without change. .

As described above, according to the game control device of the present embodiment, the predetermined condition defined in the game (in the example of FIG. 8, “lottery with coins” is selected and a predetermined amount of coins is consumed). Is satisfied, the probability that a player card that matches the player card (item) already owned by the player will appear in the lottery is reduced. In other words, for the player, there is a higher possibility that an item different from the item already owned by the player can be acquired by lottery. Thus, for example, in the case of the above-described soccer-style digital card game, the player can proceed with the progress of the game advantageously by obtaining player cards corresponding to various player characters. In addition, since it is difficult for the player cards that are already held to match newly acquired player cards, there is also an advantage that it is easy to increase the variety of player cards as one's own collection. In addition, as shown in FIG. 8, the player can select a lottery by selecting either “lottery by an ale point” that is a free lottery or “lottery by a coin” that is substantially a pay lottery. Whether or not to control the appearance probability can be determined flexibly while referring to the payable amount (balance) of the coin at the time of operation, and the interest of the game can be enhanced.

(7) Modifications Hereinafter, modifications of the above-described embodiment will be described.
(7-1) Modification 1
In the game control apparatus according to the present embodiment, the lottery control unit 522 is a player card selected by the item lottery unit 521 during a predetermined past period or a predetermined number of lottery operations in the past based on the time when the lottery operation is performed. The probability that the player card that matches (item) is not satisfied with the predetermined condition (that is, in the case of “free lottery“ the lottery with an ale point ”) than the probability that the player card is selected. You may provide the function to make it low. In other words, a player card that is a target whose probability is to be controlled (a subject that makes it difficult for the player to hold a card with a player's card) is determined based on the time when a new lottery operation is performed among the player cards held by the player. The player card is limited to a player card acquired in a past predetermined period including the latest reference or in a past predetermined number of lottery operations. By limiting the player card for controlling the probability to a certain range based on the new lottery timing, unfairness among the players due to the difference in the game start time is less likely to occur.

The function of the lottery control means 522 can be realized as follows. For example, when the player cards whose probability is to be controlled are limited to the player cards acquired during the past predetermined period, the following is performed. Each time the CPU 21 of the game server 20 acquires a new player card by lottery, the acquired player card is associated with the acquisition date and time and stored in the player database 31. Then, when reading a player card already held by the player from the player database 31 at the time of a new lottery, the CPU 21 reads only the player card associated with the acquisition date and time during the past predetermined period from the date and time of the lottery. Like that.

Also, when the player cards whose probability is to be controlled are limited to the player cards acquired during the past predetermined number of lottery operations, the following is performed. Whenever a new player card is acquired by lottery, the CPU 21 of the game server 20 sequentially stores the acquired player card in a FIFO (First In First Out) structure queue having a size corresponding to the predetermined number of times. . Such a cue may be provided in the player database 31. Then, when reading a player card already held by the player from the player database 31 at the time of a new lottery, the CPU 21 reads only the player card stored in the queue.

Note that the lottery control means 522 is at least a payment amount of the player on the game, a consumption amount of economic value, or a consumption amount of points available to the player on the game as a consideration for the lottery operation based on the player ID. The larger the value is, the longer the predetermined period may be, or the predetermined number of times may be increased. Thereby, the player can adjust himself / herself the probability that the player card obtained by the new lottery does not match the player card already held.

This can be realized as follows, for example. After recognizing that the “lottery” menu has been selected in the display example of the top page of FIG. 7, the CPU 21 of the game server 20 displays an image including a plurality of selection menus corresponding to the amount of consideration for the lottery operation. HTML data is transmitted to the communication terminal 10. An example displayed by the HTML data is shown in FIG. In the example illustrated in FIG. 13, the “lottery with coins” includes two lottery menus that make it difficult for the same player card to appear in the past week and the past two weeks. In the example of FIG. 13, 200 coins are required for the past one week, and 350 coins are required for the past two weeks. In other words, the player consumes more coins so that the same player card as the player card acquired within a longer period in the past can hardly appear.

Here, when recognizing that one of the two menus of “lottery with coins” is selected, the CPU 21 adjusts the predetermined period or the predetermined number of times according to the selection result. For example, when adjusting a predetermined period, it is as follows. When the CPU 21 reads out a player card already held by the player from the player database 31 at the time of a new lottery, the CPU 21 reads out only the player card associated with the acquisition date of the past one week or two weeks from the date of the lottery. Like that. When the predetermined number of times is adjusted, the CPU 21 may adjust the reading range of the cue provided in the player database 31 according to the number of times.

(7-2) Modification 2
In FIG. 10, as exemplified by the appearance probability data of the player card, the probability that the rare card (first item) is selected from among the plurality of player cards to be selected is the normal card (the first card) other than the rare card. When the probability that each of the plurality of items is selected is set in advance so that the item 2) is lower than the probability that the item is selected, the lottery control unit 522 may include the following functions: Good. That is, the lottery control means 522 satisfies the predetermined condition corresponding to the player ID, and if the player with the player ID already has a rare card (first item), the lottery control unit 522 selects the rare card. A function of preventing the probability of being made lower than a preset probability for the rare card. In other words, the rare card is configured to allow the player to play with the possessed card. This is because the same rare card held by a player is presented in various forms such as giving it to another player, exchanging it with a player card held by another player, or selling it to another player. This is because, since a method can be adopted, it may not always be disadvantageous for the player to hold two or more rare cards.

The function of the lottery control means 522 can be realized as follows. First, in the player database 31, all player cards are managed in association with card types (rare cards or normal cards). The card type may be determined in advance depending on whether the appearance probability set for each player card is greater than a predetermined threshold. Then, the CPU 21 of the game server 20 reads only the normal card when reading the player card already held by the player from the player database 31 at the time of a new lottery. As a result, the rare cards among the player cards held by the player are excluded from the control of the appearance probability. Needless to say, this process can be executed in combination with the first modification.

As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment. In addition, it goes without saying that each embodiment may be variously improved and changed without departing from the gist of the present invention.

In the above-described embodiment, the game server 20 and the database server 30 on the network are configured to implement the functions of the item lottery unit 521, the lottery control unit 522, and the item storage unit 541. However, the present invention is not limited to this configuration. . All these means may be realized by the communication terminal 10, or at least a part of the means may be realized by the communication terminal 10. Since the communication terminal 10 and the game server 20 can have substantially the same hardware configuration, each function can be realized by the communication terminal 10 as described in the above embodiment. For example, data relating to the contents of a plurality of items to be selected, the player ID, and the item selected by the lottery are stored in the ROM 12 or the RAM 13 in the communication terminal 10 or an HDD (Hard Disk Drive) (not shown). It may be stored in a mass storage device. The function of the lottery control means 522 can be realized in the same manner as the CPU 21 of the game server 20 by the CPU 11 with reference to the storage device in the communication terminal 10.
In addition to a server client system using the communication terminal 10 and the game server 20, a game machine (for example, a home game machine) as a game control device may include the above-described units.
