Description

  The present invention relates to a game system, a game management method, and a game management program for managing an illegal act of a player who plays a network game.

  2. Description of the Related Art In recent years, game results of players executed on a game terminal device are collected by a host via a network, and rankings of players on a nationwide scale are calculated based on the accumulation of game results of each player. The ranking is updated at the end of the game, and immediately distributed to the game device and displayed on the monitor. The higher the ranking, the higher the ranking. Since the player wants to be ranked as high as possible, he tries to leave a good game score.

  By the way, in a game played using a network, for example, a mahjong game, the opponent is generally determined according to the order of acceptance. In this case, if two players show and accept at the same time, the possibility of being assigned to the same table (same game space) increases. Then, the two players show each other and, for example, advance the mahjong game as a winning role and a losing role, so that an inappropriate act of causing the winning player to get a high score (for example, first place) It becomes feasible. Such acts are irrelevant to the player's own ability and deceive the remaining legitimate members, and this ranking is unfair with other players, so this kind of illegal act is prohibited. It is necessary to take measures.

  Patent Document 1 records participants who have won in a competition conducted in the same group, and in subsequent groupings, each participant should be in the same group as the participant who has won himself in the past. Describes how to provide a competition under equal conditions, so that the grouping is done so that it does not belong, thereby reducing the likelihood that a malicious participant will continue to collaborate with the same participant. Has been.

JP 2004-113743 A

  By the way, the fraud prevention method described in Patent Document 1 is grouped so that each participant does not become the same group as the person who won in the same group in the past every time the participation in the game is accepted, and there is room for fraud opportunities. I try to lose it. Therefore, for example, in the mahjong game, even the players who ranked first and second in the past games, and the players who ranked third and fourth, will not be grouped in the same group thereafter. In the determination method focusing only on the winning player, there is a risk that a set of players that are not necessarily connected illegally will be rejected. In addition, the number of players who have won themselves in the game, that is, the number of players who have won or lost relative to each other, rises to a large number when considering the number of games played daily, and as a result, the opponents are suddenly narrowed down. The evil that can be considered. Therefore, even if paying attention to winning or losing, there is a problem in effectively eliminating the malicious combination of players.

  The present invention has been made in view of the above, so that the collaborators who are suspected of cheating are not immediately assigned to the same game space, so that the suspicious player of the winning role is extracted. The object is to provide a game system, a game management method, and a game management program that effectively prevent fraud by not assigning players and suspected fraud partners to the same game space in a delayed manner.

According to the first aspect of the present invention, information regarding each game terminal that allows a plurality of players to play a battle game in the same game space via a network and the players that are provided on the network and participate in the battle game are provided. In the game system including a game server to be managed, the game terminal includes an accepting unit that reads identification information for identifying an individual player from a player who wants to participate, and accepts participation in the battle game. Assigns information on players accepted to the game space according to a predetermined rule, assigns the game terminal operated by the assigned player to instruct the start of a battle game, and each player at each game end Game performance and other players who played in the same game space Log storage means in which information is stored as log information, and two players obtained from the log information stored in the log storage means can quickly and effectively cooperate with each other who are suspected of committing fraud. When the number of times allocated to the same game space in a short period shorter than the following long-term period exceeds a predetermined threshold, the combination of the two players is combined. It is determined from a pair of suspected fraud players and a first fraud determination process for registering the pair of two players in the matching prohibition list recording unit, and the log information stored in the log storage means. a plurality of other players for each player, when a few days to where there is a predetermined difference to other players and results as allocation results to the same game space in a long period of about 1 week When the total frequency of the parameters indicating the frequency of matching exceeds a determination threshold that can be recognized as a winning combination who is the main culprit of inappropriate matchmaking, the player is individually registered in the matching restriction list storage unit, and then A fraud determination means for executing a second fraud determination process for registering all pairs of the player and other players allocated to the same game space in the matching prohibition list storage unit after the current allocation process; When two players who are accepted to participate in a game are registered as a set of suspicious players in the matching prohibition list storage unit, the allocation to the same game space is restricted for the two players. And a regulating means.

According to a third aspect of the present invention, in the game management method for a game server that manages information relating to a player who plays a battle game in the same game space by operating each game terminal connected to the network, the game server allocation means However, by reading identification information identifying a player individual from a player who wants to participate, information on the player accepted to participate by the game terminal is allocated to the same game space according to a predetermined rule, and the allocated player operates The game server is instructed to start a battle game, and the log storage means of the game server stores, as log information, the game results of each player and information about other players who have played in the same game space at the end of the game. Stored in the log file, and the game server fraud determining means stores the log recording. A period for preventing the two players, who are suspected of cheating, from being immediately assigned to the same game space, obtained from the log information stored in the means, and for the following long-term period When the number of times allocated to the same game space in a shorter short-term period exceeds a predetermined threshold, the pair of the two players is determined to be a group of suspected fraud players, and the two players The first fraud determination process for registering the set of information in the matching prohibition list recording unit and a plurality of other players for each player obtained from the log information stored in the log storage means for several days or when there is a predetermined difference to other players and results as allocation results to the same game space in a prolonged period of about a week, the total frequency of a parameter indicating the frequency of matching, inadequate When a determination threshold that can be recognized as a winning combination that is the chief offender is exceeded, the player is individually registered in the matching restriction list storage unit, and then allocated to the same game space as the player after the current allocation process. The second fraud determination process for registering all pairs with other players in the matching prohibition list storage unit is executed, and the restriction means of the game server is configured to allow the two players who have been accepted to participate in the battle game. When a player is registered in the matching prohibition list storage unit as a set of suspicious players, the allocation to the same game space is restricted for the two players.

According to a fourth aspect of the present invention, in a game management program of a game server that manages information relating to a player who plays a battle game in the same game space by operating each game terminal connected to a network, By reading the identification information that identifies the individual player of the player, information relating to the player accepted to participate by the game terminal is allocated to the game space according to a predetermined rule, and the battle game is started for the game terminal operated by the allocated player. The allocation means for instructing the player, the game results of each player stored in the log storage means every time the game is finished, and information regarding other players who played in the same game space can be obtained from the log information. Divide cooperators who are suspected of working in the same game space immediately. When the number of times allocated to the same game space in a short period shorter than the following long period exceeds a predetermined threshold, the pair of the two players is beaten together. Each of which is obtained from the first fraud determination process for determining the set of suspected fraud players and registering the set of the two players in the matching prohibition list recording unit, and the log information stored in the log storage means. The frequency of matching when there is a predetermined difference in performance with other players as a result of allocation to the same game space over a long period of several days or a week with a plurality of other players When the total frequency of the parameters shown exceeds a determination threshold value that can be recognized as a winning role that is the main offender of inappropriate matchmaking, the player is individually registered in the matching restriction list storage unit, After the current allocation process, the fraud determination means for executing the second fraud determination process for registering all pairs of the player and other players allocated in the same game space in the matching prohibition list storage unit, the battle When two players who are accepted to participate in a game are registered as a set of suspicious players in the matching prohibition list storage unit, the allocation to the same game space is restricted for the two players. It is a game management program that causes the game server to function as a restricting means.

According to the first, third, and fourth aspects of the present invention, when the game terminal accepts the participation by reading the identification information for identifying the individual player from the player who wants to participate, the allocation means accepts the participation. Information about the assigned player is assigned to the game space in accordance with a predetermined rule, and the game terminal operated by the assigned player is instructed to start a battle game. Each time the game is over, the log storage means stores the game results of each player and information about other players who played in the same game space as log information. The fraud determination means is a period for preventing the two players obtained from the log information from immediately assigning cooperators suspected of fraud to the same game space. When the number of times allocated to the same game space in a short period shorter than the long period exceeds a predetermined threshold, the pair of the two players is determined to be a group of suspected fraud players, and the 2 A long period of about several days to one week between the first fraud determination process for registering a set of human players in the matching prohibition list recording unit and a plurality of other players for each player obtained from the log information when there is a predetermined difference to other players and results as allocation results to the same game space during periods, total frequency parameter indicating the frequency of matching, improper mating hitting When the determination threshold that can be recognized as the winning role as the main criminal is exceeded, the player is individually registered in the matching restriction list storage unit, and after this allocation process, another player allocated to the same game space as the player A second fraud determination process for registering all pairs with the player in the matching prohibition list storage unit is executed. If two players who have received the result of the fraud determination and are allowed to participate in the battle game by the restricting means are registered as a pair of suspected fraud players in the matching prohibition list storage unit, the two players This is characterized in that the allocation to the same game space is restricted, for example, prohibited for these players.

Therefore, collaborators who are suspected of committing fraud are registered in the matching prohibition list recording unit by the first fraud determination process , so that they are not immediately allocated to the same game space, and the second fraud Through the determination process, the suspected fraudulent player who becomes the winning side is extracted and registered in the matching restriction list storage unit, and then all the pairs with this player and other players allocated to the same game space registered in the matching prohibition list storage unit, the player and as it were suspected unauthorized collaborators and (role losing), that speak to prevent delayed manner allocated to the same game space, effective fraud by regulating means attained is Do not suppressed. Note that “matching” refers to an illegal game operation in which two players are assigned to the same table and one of them is defeated and wins the other. In addition to the first-come-first-served basis, various rules can be adopted as predetermined rules for allocation, such as those that take into account differences in attributes, but at least the player's actions for allocation to the same game space Must be at least involved. For example, if it is first-come-first-served basis, it means the act of accepting at the same time. When attribute differences are involved, it refers to actions such as data tampering that match attributes in advance. In addition, the allocation performance is a value that considers the number of times allocated to the same game space, the frequency, and the like.

  In addition, according to these inventions, since the identification information for identifying the individual player is read and the participation in the game is accepted, even when a plurality of types of identification information are used properly, the same information is obtained by the second fraud determination process. Allocation to the game space is suppressed late. Furthermore, the first fraud determination process determines a situation in which the number of times allocated to the same game space during a predetermined short-term period, for example, one day, is not probabilistic (large) as determined from the total number of players. By setting as a threshold value, it is possible to more quickly extract an illegal duo for performing a match. In addition, by performing the second fraud determination process, by monitoring the allocation performance of a certain player with a plurality of other players, even if one player is impersonating another player, the fraud that makes a match It is possible to effectively extract such a duo.

According to a second aspect of the present invention, in the game system according to the first aspect, the allocating means allocates a predetermined number of persons to the same game space in the order of participation acceptance. According to this structure, it becomes possible to effectively allocate to another game space to an unauthorized participant who accepts participation at the same time.

According to the inventions described in claims 1, 3, and 4, the collaborators who are suspected of committing fraud are not immediately allocated to the same game space by the first fraud determination process. By extracting the suspected fraudulent player who is the winning player by the fraud determination process of 2, and so as not to allocate this player and the suspected fraudulent partner to the same game space lately, It can effectively deter cheating. In addition, since the identification information for identifying the individual player is read and participation in the game is accepted, even when a plurality of types of identification information are used separately, the second fraud determination process is effective for slow allocation to the same game space. Can be suppressed. Furthermore, during the predetermined period, for example, during one day, the number of times allocated to the same game space is determined from the total number of players as a predetermined threshold value, so that the number of times allocated to the same game space is set as the predetermined threshold value. An illegal duo to be performed can be extracted more quickly, and the fraud can be suppressed accordingly. In addition, by monitoring the allocation performance of a certain player with a plurality of other players, it is possible to effectively extract an illegal duo that performs a match even when one player impersonates another plurality of players. It becomes possible to do.

  According to the second aspect of the present invention, it becomes possible to effectively allocate to another game space to an unauthorized participant who accepts participation at the same time.

  As shown in the game screen of FIG. 7, the game progress control unit 161b causes the four players to play the mahjong game, and the order of the spiders is repeatedly generated in a predetermined order among the players. . In addition, the game progress control unit 161b permits a selection operation for discarding any of the handbags within a predetermined time each time a spider is generated. Therefore, each time a spider is generated, the player considers which bag is to be discarded, and performs an operation for specifying the determined bag, that is, an operation for pressing the display position of the corresponding bag object. When this operation is performed, the communication control unit 161g transmits this operation information to the other game terminal devices 1 during the battle (the virtual tables are the same, that is, the same game space), and the self and other game terminal devices. The contents of the first screen are updated, and at the next time the game terminal device 1 is in the next order.

  The score processing unit 161d determines the ranking in descending order of the number of points that the player virtually possesses as a dotted bar when the game is over. However, at the start of the game, the number of points that the player virtually possesses as a point stick (referred to as the origin) is the same. The origin is, for example, 15000 points in the case of a one-game battle, 20000 points in the case of a Dongfeng battle, and 25000 points in the case of a half-village battle. The score processing unit 161d sequentially stores the game score and the like in the game score storage unit 162b, and the stored content is transmitted to the server device 3 by the communication control unit 161g every time the game ends.

  The stage setting unit 161e determines a stage (for example, a tenth grade, a first grade, a first grade, and an eighth grade) representing the level of strength of the player on the game based on the number of items virtually owned by the player. To do. In addition, the item is moved between other players in accordance with the score obtained by the score processing unit 161d for a predetermined quantity of items virtually owned by each player. For example, two games are moved from the fourth player to the first player for each game, and one is moved from the third player to the second player.

  The title setting unit 161f virtually gives the player the title of the player in the game based on the calculated parameters when the stage is determined by the stage setting unit 161e when promoted to the first stage. . The parameters include, for example, a known completion rate, transfer rate, average number of dramas, and average conversion number. The title assigning unit 161f sets parameters by referring to the levels of the completion rate, transfer rate, average number of dramas, and average transliteration, and assigns a title corresponding to the parameter with the highest level. For example, when the level of the completion rate is the highest, the player is determined to be a haste type and given the title “Suzaku”. When the transfer rate level is the highest, the player is determined to be of the defense type and given the title “Genbu”. When the level of the average number of dora is the highest, the player is determined to be lucky and given the title “Seiryu”. When the average transliteration level is the highest, the player is determined to be offensive type and given the title “White Tiger”. Each title represents a character name that is imaged by the type of player's way of hitting (for example, haste type).

  Here, the RAM 162 of the control unit 16 will be described. The RAM 162 is the history information of the player read from the server device 3 at the start of the game, and the progress information during the battle game in the same table (same game space), and sequentially for each player, that is, through the self and the network communication unit 18. The history information storage unit 162a that stores the game progress information about all the opponents obtained and the ranking that is the game score at the end of the game of the player determined by the score processing unit 161d (if necessary, points A game result storage unit 162b that stores the number of bars, etc. for each player, and an attribute storage unit 162c that stores attributes such as the quantity and level of the item read from the server device 3 at the start of the game, and a title.

  The RAM 362 updates a player information storage unit 3620 that stores personal information such as a user ID, a results storage unit 3621 that stores game results (war results) for each player in an update manner, and attributes such as levels and titles for each player. And an attribute storage unit 3622 for storing automatically. In addition, the RAM 362 includes a log storage unit 3623 that stores information for performing determination processing by the fraud determination unit 3613. The log storage unit 3623 includes a matching frequency information storage unit 3624, a matching history information storage unit 3625, a matching restriction list storage unit 3626, a matching prohibition list storage unit 3627, a matching process list storage unit 3628, and a player list storage unit 3629. I have.

  In addition, the RAM 362 includes a ranking information storage unit (not shown) that stores the results and ranking information of all players that are sequentially calculated by a ranking calculation unit (not shown) in the CPU 361 of the control unit 36 in an update manner. . The updated ranking information is distributed to each game terminal device 1 by the communication control unit 3618 and displayed on the monitor 11 automatically or upon request.

  The matching frequency information storage unit 3624 is accumulated information within a predetermined long-term period regarding all the two players (A and B) who are in the same table, and a set of reference ID (A) and reference ID (B). Corresponding to the total number of matching and frequency parameter information. Reference ID (A) and reference ID (B) are user IDs of the players A and B. The total number of matching is the total number of matching (same table), and the frequency parameter is a parameter indicating the frequency of matching (for example, the number of times / time). The long term period is, for example, several days to one week.

  The matching history information storage unit 3625 is information for a short period of time, for example, one day regarding all the two players (A and B) in the same table, and includes a set of reference ID (A) and reference ID (B). Corresponding to the number of times of matching.

  The matching restriction list storage unit 3626 stores a reference ID that is information related to a suspicious player who is recognized as a match.

  The matching prohibition list storage unit 3627 stores a reference ID (A) and a reference ID (B) of a pair of suspected fraud players who are recognized as a match.

  The matching process list storage unit 3628 is used to obtain information related to the matching process using information from the matching frequency information storage unit 3624.

  The player list storage unit 3629 is provided for obtaining at least a reference ID having a matching history and information on the total frequency parameters.

  The log capture processing unit 3614 reads log information stored in the RAM 362 as necessary, and uses it for fraud determination processing.

  The short-term fraud countermeasure processing unit 3615 monitors a pair of players from a short-term, for example, one day worth of battle game log information, and determines the necessity of registration in the matching prohibition list based on the matching status.

  The long-term fraud countermeasure processing unit 3616 monitors the match-making situation from the log information for each player in a predetermined long-term period (several days to about one week). A process of registering a pair with a player who has become a table in the matching prohibition list is performed.

  The receiving unit 3611 receives the personal information of the user ID of the player and the identification information of the game terminal device 1 transmitted from the game terminal device 1 and receives participation in the game. Further, a mode in which a password or other authentication processing is added may be used. In addition, when participation by the player is designated by the player, the reception unit 3611 instructs the allocation unit 3612 to perform an allocation process for combining opponents.

  The allocating unit 3612 executes an opponent combination process (matching) by allocating four players to a virtually prepared table, for example, in the order of reception to the receiving unit 3611. When four players are determined on the table, the allocation unit 3612 reads out player information including the user ID of each player from the player information storage unit 3620 and distributes it to the corresponding game terminal device 1. Note that the method of selecting an opponent is not limited to the order of acceptance, and takes into account one or more factors such as player attributes included in the player information, for example, rank, title, ranking, and the location of the game terminal device. The combination may be determined.

  FIG. 7 is an example of a screen diagram of a battle screen representing the status of a mahjong game battle. In the game screen, a battle screen area 500 is set as a main area. In the battle screen area 500, the player's hand 501 is displayed on the lower side of the screen so that the type of heel can be seen, and the player's hand sword 502 is displayed on the upper and left and right sides of the screen so that the type of heel cannot be seen. In addition, a mountain 503 including a dora display bag is displayed at the approximate center of the screen, a throwing bag 504 is displayed around the mountain 503, and various buttons 506 pressed by the player are displayed at the bottom of the screen. The game proceeds by the player pressing the button 506 as appropriate while looking at the battle screen 500.

  By the way, in the case of two players who have been shown together in advance, for example, two players assigned to the same table by performing a game participation operation at the same time, one player is sacrificed, that is, loser, and the other companion This is to perform an operation that advantageously allows the player to develop the game (to win). For example, the screen of the mahjong game, as shown in FIG. 7, does not show the type of trap of the opponent players other than the player, but keeps in touch with fellow players or adjacent game terminal devices 1 By playing the game, it is possible to make an illegal match-up such as firing a type of spear that can be won by a pong etc. The fraud determination unit 3613 and the restriction unit 3617 are configured to prevent such a set of fraudulent players from being assigned to the same table.

  8 to 11 are flowcharts illustrating the mahjong game progress processing executed by the CPU 361 of the server device 3. FIG. 8 is a flowchart showing processing when a signal is received from the game terminal device 1. FIG. 9 is a flowchart showing processing when the received signal is an acceptance signal. FIG. 10 shows processing when the received signal is the game end. FIG. 11 is a flowchart showing a suspicious player extraction process executed every predetermined short period (one day).

  In FIG. 8, interruption is permitted (step S1), and whether or not a signal is received is determined (step S3). If no signal is received, this flow is exited, and if it is determined that the signal has been received, processing according to the type of the received signal is executed (step S5). Here, the reception process (FIG. 9) and the game end process (FIG. 10) are shown as examples, but other types of processes are similarly processed.

  In FIG. 9, when it is determined that the received signal is an acceptance signal, the player and the game terminal device 1 are identified from the user ID and the like in the received signal and the identification information of the game terminal device 1, and the specific information is allocated. It is transmitted to the unit 3612, and the allocation unit 3612 determines the player's table, that is, determines the combination with the player to play (step S11). When the combination is determined, necessary information such as the player information and log information of the four players included in the combination is transmitted together with the game start instruction signal to each game terminal device 1 that plays the mahjong game on the same table (step). S13).

  In FIG. 10, when it is determined that the received signal is a game end signal, log information including the game result information of the player in the received signal is captured and updated (step S21). Next, ranking processing is executed as necessary (step S23). Note that the ranking process may be executed immediately before the ranking display that is performed at the request of the player or every time the predetermined time is reached.

  In FIG. 11, it is determined whether or not a predetermined period (for example, 1 day) has elapsed with reference to an internal timer or the like (step S31). If not, it is determined that this flow has ended and that it has elapsed. Then, the short-term fraud handling process (step S33) and the long-term fraud handling process (step S35) are executed, and this flow ends.

  12 and 13 show the allocation process (step S11) executed by the CPU 361 of the server device 3, FIG. 14 shows the short-term fraud handling process (step S33), and FIGS. 15 to 18 show the long-term fraud handling process. It is a flowchart which shows (step S35).

  First, the reference ID, the attribute information such as the rank and the title, and the immediately preceding game score, which are information of the player who wants to participate in the game, are received (step S41). Next, it is determined whether or not there is a waiting table (step S43). If there is no waiting table, a new table is generated, and information of the player is registered, that is, allocated to the table (step S45). ), The process returns to step S41.

  On the other hand, if there is a stand-by table, a comparison is made with the scores immediately before the members of this table (other players already assigned to the table) (step S47). This comparison process is a determination process for preventing a match-up as much as possible by referring to the score immediately before the two players regardless of whether or not they were at the same table immediately before. For example, it is performed as follows. A winning combination threshold WP and a losing combination threshold LP are set in advance. The score immediately before the player to be determined is P, and the score immediately before the already assigned player is Pn (n is a player who is currently assigned, P1 if the first player, P2 if the first player) When P> = WP, T = 1, P <= LP, T = −1, and LP <P <WP, T = 0. Also, Tn = 1 if Pn> = WP, Tn = -1 if Pn <= LP, and Tn = 0 if LP <Pn <WP. In the above, it is appropriate for all current players if T × Tn> = 0 (Yes in Step S47), otherwise (No in Step S47). If it is not suitable, the allocation to the table is restricted, and the next table, that is, the next waiting table is shifted to determine whether or not the table is appropriate (steps S49 to S43). If none of the searched waiting tables is suitable, there is no next table (No in step S43), and the process proceeds to step S45. Note that the determination may be made based on whether or not there is a relationship between the first place and the fourth place, instead of the level of the score.

  If it is determined as appropriate in step S47, it is determined whether a combination with each member of the table is registered in the matching prohibition list (step S51). This determination is a determination process for preventing a match-up by referring to a matching result based on the number of times of matching between two players and the frequency. For example, it is performed as follows. When the reference ID of the determination target player is R and the reference ID of the already assigned player is Rn, the reference ID (A) and reference ID (B) of a certain set of players in the matching prohibition list , R ≠ reference ID (A) and Rn ≠ reference ID (B), and Rn ≠ reference ID (A) and R ≠ reference ID (B) are appropriate (suitable in step S51). Otherwise (unsuitable at step S51), it is judged unsuitable. If it is not suitable, as in the case of step S47, the flow of processing proceeds to search for the next table (steps S49 to S43).

  On the other hand, if it is determined to be appropriate in step S51, the process of allocating the player to be determined to the table, that is, the information of the player is registered (allocated) to the table (step S53).

Subsequently, it is determined whether or not the number of players assigned to the table has reached the limited number (four in this embodiment) (the combination has been determined) or the reception end time has been reached (step). S55) If this determination is negative, the process returns to step S41. In addition, when it reaches the limit number of people, it is good also as affirmation.

  On the other hand, if the determination in step S55 is affirmed, processing for the next determination is executed. That is, whether or not there is a player registered in the matching restriction list among the members of the table is determined according to the determination rule described later (step S57). If there is no player registered in the matching restriction list, the matching content in step S55 is registered as log information (step S61). Then, the table allocation process for the player who wants to participate in the next game is repeated.

  On the other hand, when there is a player registered in the matching restriction list, a combination of the matching restriction player and another player is registered in the matching prohibition list (step S59), and the process proceeds to step S61.

  FIG. 14 is a flowchart illustrating an example of the short-term fraud countermeasure processing. First, matching history information that is log information of the previous day is read from the top (step S71). In the present embodiment, this reading process is for monitoring log information for the past one day, but this process is assumed to be at the end of business on one day or at the start of business on the next day.

  In reading from the first row, it is determined whether or not there is matching history information for the combination of two players (step S73). If there is no matching history information, this flow is exited. On the other hand, if there is matching history information, it is determined whether or not the number of matching times for the set of reference ID (A) and reference ID (B) is equal to or greater than a threshold value N (step S75). The value N is a threshold value for determining the matching. If the number of matching of the pair of reference ID (A) and reference ID (B) is greater than or equal to the threshold value N, the pair is registered in the matching prohibition list (step S77), and conversely, the reference ID (A) and reference ID ( If the number of matchings in the group B) is less than the threshold value N, step S77 is skipped and the process proceeds to step S79. In step S79, the matching history information for the next set is read, and the process returns to step S73 to monitor all the matching history information.

  15 to 18 are flowcharts showing an example of the long-term fraud countermeasure processing. First, the data of the matching process list and the player list are cleared (empty) every day, and the matching frequency information is read (step S81). Next, the value 1 is uniformly subtracted from the frequency parameter in the read matching frequency information (step S83). This is such that the frequency is reduced by one day each time. Next, the previous day's matching history information is read from the first line (step S85). Then, the presence / absence of matching history information is determined (step S87). If there is matching information, it is determined whether or not there is the same information as the matching frequency information, that is, the same reference ID (A) and reference ID (B). Determination is made (step S89). If there is no same group, new registration is performed in the matching frequency information (step S91). Then, in the newly registered matching frequency information, the frequency parameter is set to Pi, and the total number of matching is set to the number of matchings. Note that the value Pi is a frequency parameter initial value that is a basis for determining a match.

  On the other hand, if there is the same set in step S89, the matching frequency information is rewritten (step S93). That is, the frequency parameter is updated to the number of matching times + Pb, and the total number of matching is updated to the number of matching times. Note that the value Pb is a frequency parameter penalty value that can be determined as a match. Next, the matching frequency information of the next line is read (step S95), and the process returns to step S87.

  On the other hand, if all the matching history information is read and it is determined that there is no matching history information in step S87, the matching frequency information whose frequency parameter is 0 or less is deleted from the matching frequency information (step S97). . Next, reading of the matching frequency information from the first line is started (step S99). Then, the presence / absence of matching frequency information is determined (step S101). If there is matching frequency information, it is determined whether the frequency parameter of the matching frequency information is greater than or equal to the value A1 (step S103). The value A1 is a determination threshold value for determining the presence / absence of matching. If the frequency parameter of the matching frequency information is greater than or equal to the value A1, this matching frequency information is added to the matching process list (step S103), and then the next line matching frequency information is read (step S107), and step S101. Return to.

  On the other hand, if the frequency parameter of the matching frequency information is less than the value A1, step S105 is skipped and the process proceeds to step S107.

  If there is no matching frequency information in step S101, the matching process list is read from the first line (step S109), and the presence / absence of the matching process list is determined (step S111). If there is a meeting processing list, it is first determined from the meeting processing list whether or not the reference ID (A) is registered in the player list (step S113). When the reference ID (A) is registered in the player list, the information of the reference ID (A) in the player list is rewritten (step S115), and the process proceeds to step S119. In the rewriting of the reference ID (A) of the player list, the frequency parameter of the meeting processing list is written in the frequency parameter total column. On the other hand, when the reference ID (A) is not registered in the player list, the reference ID of the player list in which the player with the reference ID (A) is newly registered in the player list and the frequency parameter of the meeting processing list is newly registered. (A) is written in the frequency parameter total column (step S117), and the process proceeds to step S119.

  In step S119, it is next determined whether or not the reference ID (B) is registered in the player list. When the reference ID (B) is registered in the player list, the information of the reference ID (B) in the player list is rewritten (step S121), and the process proceeds to step S125. In rewriting the reference ID (B) of the player list, the frequency parameter of the matching process list is written in the frequency parameter total column. On the other hand, when the reference ID (B) is not registered in the player list, the player with the reference ID (B) is newly registered in the player list, and the reference of the player list in which the frequency parameter of the matching process list is newly registered is referred to. It is written in the frequency parameter total column of ID (B) (step S123), and the process proceeds to step S125. Next, in step S125, the next line matching process list is read, and the process returns to step S111.

  On the other hand, if there is no matching process list in step S111, the player list is read from the first line (step S127), and the presence or absence of the player list is determined (step S129). If there is a player list, it is determined whether the total frequency parameter of the player list is greater than or equal to the value A2 (step S131). The value A2 is a determination threshold value that allows a player to be recognized as a winning combination that is a main culprit of inappropriate matchmaking.

  If the sum of the frequency parameters is equal to or greater than the value A2, the player is registered in the matching restriction list (step S133), then the next player list is read (step S135), and the process returns to step S129. On the other hand, if the frequency parameter sum is less than the value A2, step S133 is skipped and the process proceeds to step S135.

  In addition, the following aspects are employable for this invention.

(1) Although the present invention has been described as a mahjong game as an example of a battle game, the present invention is not limited to this, and any game can be applied as long as it is a battle game played by at least three players.

(2) In this embodiment, the reference ID (A) and the reference ID (B) are registered only in the matching history information in the matching history information. Instead, the reference ID (A) and the reference ID (B) are registered. The game may be registered when the game results are 1st and 4th. According to this, the monitoring accuracy of the matching is improved.

(3) In the present embodiment, the matching frequency of the matching history information and the frequency parameter of the matching frequency information are calculated only by the presence / absence of matching, but instead of this, reference ID (A), reference ID ( B) If the rank is 1st and 4th, 1st and 3rd, 1st and 2nd, so that the possibility of matching can be judged more accurately Depending on, weighting may be performed. Moreover, you may include the case where it was 2nd and 4th. In short, it is possible to include a level at which one can be recognized as a winning role and the other can be recognized as a losing role.
