Game system, game management method, and game management program

Abstract

This game system has an allocation unit ( 3612 ) for allocating players, who wish to participate in a versus game, to a game space, a log acquisition processing unit ( 3614 ) for storing, as log information, other players who played in the same game space every time the game ends, fraud determination means ( 3613 ) for performing first fraud determination processing of registering in a partnering prohibition list a team of two players determined to be suspected fraud players based on the log information, and second fraud determination processing of registering teams of a fraud player and each of the other players allocated to the same game space in the partnering prohibition list based on the log information, and a restriction unit ( 3617 ) for restricting the allocation of a team of suspected fraud players registered in the partnering prohibition list to the same game space. Whereby, the allocation of collaborators who are suspected of committing fraud to the same game space can be prevented.

 the game terminal has acceptance means for accepting entries to the versus game, and   the game server has:   allocation means for allocating players, whose entry has been accepted, to the game space according to predetermined rules;   log storage means for storing, as log information, game scores of the respective players, and other players who played a versus game in a same game space every time the game ends;   fraud determination means for performing:
 first fraud determination processing of determining, based on a record of allocation to the same game space of a team of two players who have been allocated to the same game space which is obtained from the log information, whether those two players are suspected fraud players committing joint discard, and registering in a partnering prohibition list the team of the two players when those two players are determined to be suspected fraud players, and 
 second fraud determination processing of determining, based on a record of allocation to the same game space of each player in relation to a plurality of other players which is obtained from the log information, whether that player is a suspected fraud player committing joint discard, and registering in the partnering prohibition list teams of that fraud player and each of the other players allocated to the same game space when that player is determined to be a suspected fraud player; and 
   restriction means for restricting the allocation of two players to the same game space when those two players whose entries to the versus game have been accepted are registered as a team of suspected fraud players in the partnering prohibition list.   
     
     
         2 . The game system according to  claim 1 , wherein the acceptance means includes a reading unit for reading identification information on a player from a recording medium recorded with the identification information on that player. 
     
     
         3 . The game system according to  claim 1 , wherein the allocation means allocates a predetermined number of players to the same game space according to the order of entry acceptance. 
     
     
         4 . The game system according to  claim 1 , wherein the first fraud determination processing determines a team of two players to be suspected fraud players when the number of times that the two players have been allocated to the same game space during a predetermined period exceeds a predetermined threshold. 
     
     
         5 . The game system according to  claim 1 , wherein the second fraud determination processing determines a team of players to be suspected fraud players when an allocation frequency according to the record of allocation of a certain player and the plurality of other players to the same game space exceeds a predetermined threshold. 
     
     
         6 . The game system according to  claim 1 , wherein the restriction means restricts the allocation of two players to the same game space upon determining that a win/loss record of the last versus game of each of those two players whose entries to the versus game have been accepted shows that one of those players was a winner and the other one of those players was a loser. 
     
     
         7 . The game system according to  claim 1 , wherein the fraud determination means reads the log information daily and updates registration information of the partnering prohibition list. 
     
     
         8 . A game management method of a game server which manages players who play a versus game in a same game space by operating respective game terminals connected to a network, wherein
 allocation means allocating players, whose entry has been accepted, to the game space according to predetermined rules,   log storage means storing, as log information, game scores of the respective players, and other players who have played a versus game in the same game space every time the game ends,   fraud determination means performing
 first fraud determination processing of determining, based on a record of allocation to the same game space of a team of two players who have been allocated to the same game space which is obtained from the log information, whether those two players are suspected fraud players committing joint discard, and registering in a partnering prohibition list the team of the two players when those two players are determined to be suspected fraud players, and 
 second fraud determination processing of determining, based on a record of allocation to the same game space of each player in relation to a plurality of other players which is obtained from the log information, whether that player is a suspected fraud player committing joint discard, and registering in the partnering prohibition list teams of that fraud player and each of the other players allocated to the same game space when that player is determined to be a suspected fraud player, and 
   restriction means restricting the allocation of two players to the same game space when those two players whose entries to the versus game have been accepted are registered as a team of suspected fraud players in the partnering prohibition list.   
     
     
         9 . A game management program of a game server which manages players who play a versus game in a same game space by operating respective game terminals connected to a network,
 the game management program causing the game server to function as:   allocation means for allocating players, whose entry has been accepted, to the game space according to predetermined rules;   log storage means for storing, as log information, game scores of the respective players, and other players who have played a versus game in the same game space every time the game ends;   fraud determination means for performing first fraud determination processing of determining, based on a record of allocation to the same game space of a team of two players who have been allocated to the same game space which is obtained from the log information, whether those two players are suspected fraud players committing joint discard, and registering in a partnering prohibition list the team of the two players when those two players are determined to be suspected fraud players, and second fraud determination processing of determining, based on a record of allocation to the same game space of each player in relation to a plurality of other players which is obtained from the log information, whether that player is a suspected fraud player committing joint discard, and registering in the partnering prohibition list teams of that fraud player and each of the other players allocated to the same game space when that player is determined to be a suspected fraud player; and   restriction means for restricting the allocation of two players to the same game space when those two players whose entries to the versus game have been accepted are registered as a team of suspected fraud players in the partnering prohibition list.
