## Title
Game terminal device, game management system and game management method

## Abstract

A game management method is for executing a competition game among a plurality of client terminal devices. Players are identified before the start of the game. If an occurrence of an unusual end of the game is judged during the game, it is judged whether or not the unusual end is an unauthorized end of the game due to an unauthorized operation by the player and it is judged whether or not a penalty is to be given to the player having ended the game in an unauthorized manner. By judging with high accuracy whether or not the unusual end of the game was caused by the unauthorized operation by the player, unauthorized operations of players are suppressed and fairness is better maintained among honest players.

## Background
FIELD OF TECHNOLOGY
The present invention relates to a game terminal device, a game management system and a game management method capable of executing a competition game by exchanging operation information with each other via a network.
BACKGROUND TECHNOLOGY
In recent years, competition games have been made playable among a plurality of shops via a network. In game terminal devices of this type, game results are collected by a central server, ranking in the entire country, area or shop is calculated based on the game results of players, the calculated ranking is displayed in the game devices at the end of the game or various awards (virtual honors, ranks, grades, etc.) determined in the game are given. Participation in the game is urged by displaying the ranking of top scorers and giving awards in this way.
A player tries to get a good game result in each game because he desires to be ranked high even in games. However, if such desire increases, there is a possibility of such a player psychology as not to leave a game result disadvantage to himself since his ranking may be lowered if the game ends when he loses ground while playing the game. As a result, the player may try to prevent the transmission of the game result to a central server before the game thought to end up with an unfavorable result is normally ended.
For example, it is thought to prevent the transmission of the game result to a host by turning a power switch of the game device off or shutting a network cable off to forcibly end (unusual end) the game during the game in the shop. In the case of such hindrance to the transmission of the game result to the central server, the ranking of the player having done such an action is hardly lowered in the end. Accordingly, the game result is not correctly reflected on the ranking, making a fair ranking process or its display impossible, wherefore the ranking becomes unfair to honest players.
There can be also thought a method for monitoring an occurrence of unusual end and preventing the participation of a player having done many unusual ends in the game assuming that he is conducting an unauthorized operation. However, there is a certain limit in relating the number of unusual ends and true unauthorized operations.
DISCLOSURE OF THE INVENTION
In view of the above, an object of the present invention is to provide technology capable of suppressing cheating acts of players.
Another object of the present invention is to provide a game terminal device, a game management system and a game management method capable of highly accurately judging whether an unusual end of a game is caused by an unauthorized operation by a player or an unavoidable occurrence such as blackout or network failure to suppress unauthorized operations of players and to maintain fairness among honest players.
According to one aspect of the present invention, a game capable of executing a competition game among a plurality of game terminal devices by exchanging operation information with each other via a network, players are identified before the start of the game; it is judged whether or not the game in process has been ended in an unusual manner; it is judged whether or not the unusual end is an unauthorized end of the game due to an unauthorized operation by the player; and it is judged whether or not a specified penalty is to be given to the player having ended the game in an unauthorized manner.
In this way, unauthorized operations of players can be suppressed and fairness can be maintained among honest players.
These and other objects, features and advantages of the present invention will become more apparent from an embodiment described with reference to accompanying drawings.

First of all, the individual information transmitted from the client terminal devices 1 is received by the receiving section 361a (Step ST1). The players are authenticated based on the player information stored in the player information storage 362a and the participation of the players in the game is permitted if the authentication result is affirmative (Step ST3). Subsequently, out of the players whose participations were received by being permitted by the receiving section 361a (received not in the case of a “one-on-one game” mode to be described later), two or more players who will play in the same space are selected based on the grades stored in the rank storage 362b and the titles stored in the title storage 363c by the selecting section 361b, and instruction information to the effect of causing the players selected by the selecting section 361b to play the game in the same game space is transmitted to the client terminal devices 1 used by the selected players by the first executing section 361d (Step ST5). Then, the used states of all the client terminal devices 1 caused to execute the game by the first executing section 361d are monitored by the monitoring section 361g (Step ST7).
FIG. 10 is an exemplary detailed flow chart of Step ST5 (competitor determination process) shown in FIG. 9. The following process is performed by the selecting section 361b unless otherwise specified. First of all, a competition mode transmitted from the client terminal device 1 is received by the receiving section 361a (Step ST51). There are three modes of “one-on-one competition”, “in-shop competition” and “communication competition”. In the “one-on-one competition” mode, the player competes with a CPU player. In the “in-shop competition” mode, all the competitors are using the client terminal devices 1 connected to the same shop server 2. in the “communication competition” mode, at least one of the competitors is using the client terminal device 1 connected to a different shop server.
Subsequently, it is judged by the receiving section 361a whether or not the competition mode is the “one-on-one competition” mode (Step ST52). This process routine is returned if this judgment result is affirmative. If this judgment result is negative, the player is received, a time counter T is initialized to 0 (Step ST53) and instruction information is transmitted to the client terminal device 1 used by this player so that a standby screen shown in FIG. 11 is displayed.
FIG. 11 is a diagram showing an exemplary standby screen. On a standby screen 400, player information 401 of the player where this screen is displayed is displayed at a lower side, pieces of player information 402, 403 indicating no selection of competitor are displayed at upper and right sides, and player information 404 of a CPU player is displayed at a left side. The pieces of player information 401, 404 displayed include names 401a, 404a as the names of the players in the game, titles 401b, 404b of the players and ranks 401c, 404c of the players. For example, the name of the CPU player is “Hanako”, the title thereof is “Genbu” and the rank thereof is “4th dan”. Since the pieces of player information 402, 403 of the competitors other than the player using the client terminal device 1 displaying the standby screen 400 and the CPU player are not displayed on the standby screen 400, this player can confirm that the competitors are not selected yet.
Referring back to FIG. 10, it is judged whether there are any players kept in the standby state by the standby section 361c or any already received players (Step ST55). This routine proceeds to Step ST61 if this judgment result is negative. If this judgment result is affirmative, two or more, but three or less players who will play in the same game are selected from the received players and those kept in the standby state by the standby section 361c based on the grades stored in the rank storage 362b and the titles stored in the title storage 363c (Step ST57) and instruction information is transmitted to the client terminal devices 1 used by these players so as to display a standby screen showing the selected result.
FIG. 12 is a diagram showing an exemplary standby screen showing a selected result. On a standby screen 410, player information 411 of a player where this screen is displayed is displayed at a lower side, player information 413 indicating no selection of competitor is displayed at an upper side, player information 414 of a CPU player is displayed at a left side and player information 412 of a player selected by the selecting section 361b is displayed at a right side. The pieces of player information 411, 412 and 414 displayed include names 411a, 412a and 414a as the names of the players in the game, titles 411b, 412b and 414b of the players and ranks 411c, 412c and 414c of the players. Since the player information 412 of the player (competitor) selected by the selecting section 361b is displayed in addition to those of the player using the client terminal device 1 displaying the screen and the CPU player, the player using the client terminal device 1 displaying this screen can confirm that one competitor has been selected.
Referring back to FIG. 10, it is judged whether or not the number of the selected players (number of the competitors) in Step ST57 is 3 (Step ST59). This process routine is returned if this judgment result is affirmative. If this judgment result is negative, the time counter T is incremented (Step ST61) and it is judged whether or not the value of the time counter T is a specified time TMAX (here, 30 sec.) (Step ST63). Step ST53 follows if this judgment is negative. If this judgment result is affirmative, it is judged whether or not the number of the players selected in Step ST57 is 0 (i.e. no player was selected) (Step ST65). If this judgment result is affirmative, players are kept in the standby state by the standby section 361c (Step ST67). If this judgment result is negative, this process routine is returned.
FIG. 13 is an exemplary detailed flow chart of the process (process in the standby state) in Step ST67 shown in FIG. 10. The following process is performed by the standby section 361c unless otherwise specified. First of all, instruction information is transmitted to the client terminal devices 1 to start the CPU competition (competition only with the CPU player) (Step ST671).
It is judged whether or not a specified time (e.g. 30 sec.) has elapsed (Step St677), and elapsed time is counted up until this judgment result becomes affirmative. If this judgment result is affirmative, player selection is performed by the selecting section 361b (Step ST679) and it is judged whether or not a player in the standby state has been selected (Step ST681). If this judgment result is affirmative, Step ST683 is followed, in which instruction information is transmitted to the client terminal device 1 to display a competitor appearing screen showing the selection of the player. This routine returns to Step ST677 if this judgment result is negative.
If the judgment result in Step ST681 is affirmative, it is judged whether or not the number of the selected players is 3 (Step ST683). If this judgment result is affirmative, Step ST7 (competition monitoring process) of FIG. 9 follows. If this judgment result is negative (if one player was selected), it is judged whether or not a specified time (e.g. 10 sec.) has been elapsed (Step ST685) and elapsed time is counted up until this judgment result becomes affirmative. If this judgment result is affirmative, the player selection is performed by the selecting section 361b (Step ST687) and Step ST7 (competition monitoring process) of FIG. 9 follows.
FIG. 14 is an exemplary detailed flow chart of the process (player selection process) in Step ST57 shown in FIG. 10. It should be noted that the process in Step ST57 shown in FIG. 10 is the same process in Steps ST679 and ST687 shown in FIG. 13. The following process is entirely performed by the selecting section 361b. First of all, a total number WN of the player(s) in the standby state and the received player(s) is counted (Step ST571) and then a player number counter I is initialized (Step ST573). Then, it is judged whether or not later-described cheater levels of this player and the Ith player are same based on information read from the cheater information storage 362e (Step ST575), and Step ST583 follows if this judgment result is negative. If this judgment result is affirmative, the ranks of this player and the Ith player are read from the rank storage 362b and it is judged whether or not a rank difference is equal to or below a specified value DN (here, 2) (Step ST577). Step ST583 follows if this judgment result is negative. If this judgment result is affirmative, the Ith player is added as a player to compete with this player (Step ST579).
Subsequently, it is judged whether or not the number of the players to compete with this player is 3 (Step ST581). This process routine is returned if this judgment result is affirmative. If this judgment result is negative or if the judgment result in Step S575 or ST577 is negative, the player number counter I is incremented (Step ST583) and it is judged whether or not the value of the player number counter I has exceeded the player total number WN (Step ST585). This process routine is returned if this judgment result is affirmative while being returned to Step ST575 if it is negative.
Here, the operation of the client terminal device 1 performed based on instructions from the above central server 3 is described. FIG. 15 is an exemplary flow chart showing the operation of the client terminal device 1. First of all, a user ID of an individual card inserted into the card reader 13 is read, the fingerprint of the player is picked up by the CCD camera 14a of the fingerprint authenticator 14, and feature data necessary for individual authentication are extracted by the fingerprint authenticator 14 using fingerprint information from the CCD camera 14a (Step ST101). Then, the user ID data and the feature data are transmitted to the central server 3 (Step ST103). A mode selection screen used to select the competition mode is displayed and an input from the player is received to select the competition mode (Step ST104), and competition mode information is transmitted to the central server 3.
The names, ranks, titles, etc. of the other players (competitors) who will play the game in the same game space are received from the central server 3 (Step ST105). Subsequently, upon receiving instruction information to the effect of executing the game from the central server 3, the game is started and a round and a dealer are determined (Step ST107). Then, the competition is started (Step ST109) and a competition screen shown in FIG. 16 is displayed.
FIG. 16 is a diagram showing an exemplary competition screen showing a status of competition. On a competition screen 510, hand tiles 511 of the player are so displayed at a lower side that the types of the tiles can be seen, hand tiles 512 of the competitors are so displayed at upper, left and right sides that the types of the tiles cannot be seen, a mountain wall 513 including lucky ‘dora’ displaying tiles is displayed substantially in the center with discarded tiles 514 displayed around the mountain wall 513, and various buttons 516 to be pressed down by the player are displayed at the bottom. The game proceeds by the player suitably pressing the buttons 516 down while seeing the competition screen 510.
Referring back to the flow chart of FIG. 15, when the competition is started, the life is calculated by the life calculating section 161k and it is judged whether or not the life exceeds 0 HP (1 HP or larger) (Step ST111). Step ST117 follows if this judgment result is affirmative. If this judgment result is negative, a continuation selection screen for urging the player to judge whether or not to continue the competition is displayed and the judgment of the player is received based on whether or not coins have been received by the coin receiver 15, thereby judging whether or not to continue the competition presently being executed (Step ST113). If this judgment result is negative, competition interrupt information to the effect of interrupting the competition is transmitted to the central server 3 (Step ST115) and this process is ended. This routine returns to Step ST109 if this judgment result is affirmative.
If the judgment result in Step ST111 is affirmative, it is judged whether or not the competition has been ended (Step ST117). Step ST109 follows if this judgment result is negative. If this judgment result is affirmative, competition end information indicating the end of the competition is transmitted to the central server 3 and the ranking in the game is judged by the result judging section 161b (Step ST119). Then, items virtually possessed by the player are transferred among the players by the item transferring section 161d based on the judgment result by the result judging section 161b and the number of rounds selected by the table selecting section 161c (Step ST121). Subsequently, the rank representing the player's strength in the game is determined by the rank determining section 161f based on the number of items and the points virtually possessed by the player and is compared with the rank thus far (at the end of the last game) stored in the rank storage 162a to judge whether or not to change the rank to the first dan (Step ST123). If the rank is not changed to the first dan, an unillustrated item displaying screen showing the number of presently possessed items is displaced and Step ST129 follows. The rank determined by the rank determining section 161f is stored in the rank storage 162a and transmitted as rank information to the central server 3.
If the rank is changed to the first dan, title parameters representing features of the player in the game are calculated by the title parameter calculating section 161g (Step ST125). Then, the title of the player in the game is virtually assigned to the player by the title assigning section 161h based on the title parameters calculated by the title parameter calculating section 161g (Step ST127) and are stored in the title storage 162c and transmitted as title information to the central server 3.
Subsequently, it is judged whether or not the present HP of the life is equal to or above a specified value SL (here, 5000 HP) necessary to continue to play the game (Step ST129). If this judgment result is affirmative, a continuation selection screen is displayed, an input from the player is received and it is judged whether or not the game is continued (Step ST131). This routine returns to Step ST103 if this judgment result is affirmative while proceeding to Step ST135 if it is negative.
If the judgment result in Step ST129 is negative, the continuation selection screen is displayed, the judgment of the player is received based on whether or not coins have been received by the coin receiver 15 and it is judged whether or not to continue the game (Step ST133). This routine returns to Step ST103 if this judgment result is affirmative while proceeding to Step ST135 if it is negative.
If the judgment result in Step ST133 or ST131 is negative, the competition end information indicating the end of the game is transmitted to the central server 3 (Step ST135) and this process is ended.
FIG. 17 is an exemplary flow chart of a process of obtaining information on an unusual end state, which process is a part of the process “Competition” in Step ST109 of FIG. 15 and performed by the log data managing section 161o. 
The unusual end state here is referred to as a case where at least one of the communication cable 8 and the power supply line 9 of the client terminal device 1 operated by the player is pulled out from the outlet 7, a case where a temporary communication failure occurs between the client terminal device 1 and the client terminal device 1 of the competitor and operation or use information cannot be transmitted from this client terminal device 1 to the client terminal device 1 of the player and a case of momentary or temporary blackout (momentary stop) by unusual power supply condition. The information processor 161 performs the following process to continue the subsequent game upon the occurrence of the unusual end state. Specifically, in the case where the communication cable 8 of the client terminal device 1 operated by the player is pulled out from the outlet 7 by the player, information for the game progress cannot be transferred to and from the other client terminal devices 1 being competing. Thus, for example, the client terminal device 1 having the smallest selection number set during the above selection process out of the client terminal devices 1 being competing performs a process of newly setting a CPU player, and the other client terminal devices 1 having competed continue the game using simulated operation information by the CPU player for the continuation of the game. Further, similarly in the case where the power supply line 9 of the client terminal device 1 operated by the player is pulled out from the outlet 7 by the player, this client terminal device 1 does not operate. Thus, information for the game progress cannot be transferred to and from the other client terminal devices 1 being competing, the above process of newly setting a CPU player is performed, and the other client terminal devices 1 having competed continue the game using simulated operation information by the CPU player for the continuation of the game. In this case, since it is hard on honest players if the game is ended in failure, the game records corresponding to the client terminal devices 1 operated by the honest players are treated as the game results and accumulated in the central server 3.
In this embodiment, the unusual end state does not mean to forcibly end the game itself in the client terminal device being competing, but means to switch the client terminal device 1 where an unauthorized operation was conducted or an unusual condition occurred to a CPU player, i.e. means that the game is no longer a game played among the original competitors. Of course, the unusual end state may mean that the game itself is forcibly ended.
Referring back to FIG. 17, when the game is started, elapsed time is measured by a built-in timer, each client terminal device 1 constantly temporarily saves the respective game modes of “one-on-one competition”, “in-shop competition” and “communication competition”, ranking in the game, time and points when a losing discard was made out of the information concerning the operation of the player and the game statuses as log data in a specified area of the RAM 162. It is judged whether or not a log data leaving period (LOG PERIOD) has elapsed up to the present time after the saving of the latest log data (Step S151) and, if this judgment result is affirmative, the log data are stored in a log file, here, in the history storage 162b (Step S153). Subsequently, the present time is replaced as the last log time (Step ST155). On the other hand, if the game normally ends, the log file is deleted (Step ST157). Accordingly, if the game ends in an unusual end state, the game mode, the ranking, the time and points when the losing discard was made are present in correspondence with the authenticated player in the history storage 162b of the client terminal device 1 where unusual condition occurred.
FIG. 18 is an exemplary flow chart of a log data processing performed by the log data managing section 161o, which is a part of a process at the time of starting the client terminal device. If the player inserts the power supply line 9 into the outlet 7 after pulling it out from the outlet 7, the client terminal device is turned on again. After the client terminal device 1 is started, it is first judged whether or not any log data file is present in the history storage 162b (Step ST161). If the judgment result is negative, this routine returns, assuming that there was no unusual end. On the other hand, if this judgment result is affirmative, the log data file is read from the history storage 162b (Step ST163) and the read log data are transmitted to the central server 3 as unusual information (Step ST165). Thereafter, the log file is deleted (Step ST167). Also when the player inserts the communication cable 8 again after pulling it out from the outlet 7, the log data stored in the history storage 162b of this client terminal device are transmitted to the central server 3 after the communication is interrupted for a specified period.
FIG. 19 is an exemplary flow chart of a log file importing process by the central server 3. In the central server 3, the monitoring section 361g judges whether or not the data being transmitted from the client terminal device includes any log data (Step ST171) and this routine returns if this judgment result is negative. On the other hand, if this judgment result is affirmative, the monitoring section 361g performs the following process. First of all, a cheat point (black point) file based on the player information is generated in a specified area of the RAM 362 (Step ST173). Subsequently, based on the received log data, cheat points weighted according to the ranking are set (Step ST175). Here, if the rank was in the first place, the cheat point is set to 0, assuming no intension of cheating (e.g. caused by communication failure or momentary stop). If the rank before the losing discard was in the second place, a cheat point is set to 1, assuming a small intension of cheating. If the rank before the losing discard was in the third place, cheat points of 4 are set, assuming a large intention of cheating. If the rank before the losing discard was in the fourth place (lowest rank), cheat points of 16 are set, assuming cheating (at least one of the communication cable 8 and the power supply line 9 was pulled out from the outlet 7). Weighting may not be necessary. For example, cheat points may be given only to the player in the lowest rank. Various weighting modes for the ranks can be thought. For example, cheat points may be set for inferior players (here, third and fourth places).
If the losing discard is effective, weighted cheat points are set (added) according the points when the losing discard was made (Step ST177). A condition for making the losing discard effective is, here, such that an unauthorized operation is performed within a specified period of, e.g. 3 min. after the losing discard was made. If the points when the losing discard was made were equal to or below 8000, cheat points of 2 are set, assuming a small intention of cheating and added to the points given in Step ST175. If the points when the losing discard was made were from 8000 to 16000, cheat points of 8 are set, assuming a large intention of cheating and added to the points given in Step ST175. If the points when the losing discard was made were above 16000, cheat points of 16 are set, assuming that an unauthorized operation was conducted (at least one of the communication cable 8 and the power supply line 9 was pulled out from the outlet 7) and added to the points given in Step ST175. Accordingly, 32 cheat points are set when the rank was in the fourth place and the points when the losing discard was made were above 16000. Various weighting modes can be thought for the points when the losing discard was made. For example, cheat points may be set only for the player in the lowest rank or inferior players (here, third and fourth places).
The monitoring section 361g reads the data of the same player as the owner of the log data from the cheater information storage 362e, and the cheat points calculated this time and a cheat count of 1 are added to the cheater information of this player to update the data of this player in the cheater information storage 362e. In the case of a player to whom the log data is issued for the first time, no data is present in the cheater information storage 362e for this player. Thus, new data are generated and written. The cheat points are set according to the rank and the points when the losing discard was made, but may be set according to either one of them or other element(s) may also be considered for the setting.
FIG. 20 is an exemplary flow chart of a cheater confirmation process performed as a part of the user authentication process. This flow is started when the individual information of the player wishing to participate in the game is received from the client terminal device 1. It is judged whether or not there is any cheat history corresponding to the user ID data authenticated in the player authentication process in the cheater information storage 362e (cheat DB) (Step ST181). In the absence of the cheat history, this routine returns with the cheat count and the cheat point set to 0 (Step ST183), assuming that an authentication result indicates an honest player. On the other hand, if the cheat history is present, cheat information, i.e. the cheat count, the cheat points and the time of the last cheating were read from the cheater information storage 362e (Step ST185). Then, it is judged whether or not the cheat history has exceeded a specified threshold value, here, whether or not the cheat count is equal or above a specified number, e.g. 3 and an average cheat point as one kind of cheat parameters is equal to or above a specified value, e.g. 1 (Step ST187). The average cheat point as one kind of cheat parameters is calculated by (cheat points)/(cheat count). That the average cheat point exceeding 1 can be judged to be a high possibility of an unauthorized operation. If this judgment result is negative, the player is judged to be normal in the authentication result, assuming a small intension of cheating, and the participation in the game is permitted after a cheater level comprised of the cheat count and the cheat points is set (Step ST189). On the other hand, if the judgment result is affirmative, it is judged whether or not (present time−last cheat time) is equal to or shorter than {3 hours+(cheat count−3)×24 hours} (Step ST191). For example, if the cheat count is 5 and 51 hours have not elapsed yet from the last cheat time, the above judgment result is negative. This is because restriction is moderated with respect to time to give a so-called improvement chance to clean up one's act in consideration of the cheat count for a player whose has not cheated for a long time after the last unauthorized operation. If this judgment result is negative, a high possibility of improvement is assumed and the player is judged to be normal in the authentication result and permitted to participate in the game (Step ST189). In the competition game in Step ST189, a specified title notifying a competition by cheaters, e.g. “PENALTY MODE” is displayed at a specified position of the competition screen as shown in FIG. 21.
On the other hand, if the above judgment result is affirmative, a process of prohibiting the participation of the player in the game is performed, identifying the player as a habitual cheater (Step ST193). As the process of prohibiting the participation of the player in the game, a message of “play prohibition” is, for example, displayed on the monitor 11 of the client terminal device 1.
By the process of FIG. 20, the process of judging the cheater levels in Step ST75 of FIG. 14 is made possible. Specifically, in Step ST75 of FIG. 14, the players having the same cheater level are caused to play the competition game with restriction placed on the competition with honest players. Thus, a possibility that honest players suffer inconveniences from unauthorized operations can be maximally prevented. For example, players having the same cheater level or similar cheater levels can be caused to compete, utilizing a degree of malice as one kind of the cheat parameters. In this case, an indication or warning to the effect that this competition game is played only by cheaters can be individually displayed at suitable positions of the selection screens of the competitors as shown in FIG. 21 or at suitable positions of game screens during the game, thereby suppressing unauthorized operations.
The cheater level is one kind of the cheat parameters and may be calculated as the average cheat point, which is the ratio of the cheat points to the cheat count. Further, a degree of malice calculated by the following equation may be used as a cheat parameter.

Degree of malice=INT((cheat points/cheat count)/4)

For example, if the cheat points are 28 and the cheat count is 5, the degree of malice is 1 by the above equation.
The present invention may be embodied as follows.
(A) Although the game executed by the client terminal devices 1 is a mahjong game in this embodiment, it may be another game played by a plurality of players. For example, it may be a card game, a go game, a shogi game, a shooting game, a racing game or the like.
(B) Although the shop servers 2 are provided in this embodiment, the client terminal devices 1 may be connected to the central server 3 via the network.
(C) Although coins are inserted into the coin receiver 15 at the time of continuing the game in this embodiment, the present invention is not limited thereto. For example, a card may be received instead of the coins.
(D) The construction of this embodiment connecting the central server 3, the shop servers 2 and the client terminal devices 1 is not limited to the one shown in FIG. 1. For example, without using the shop servers 2, the client terminal devices 1 and the central server 3 can be thought to be connected in various modes including a ring type, a tree type, a star type and the like. In this case, the tree type connection mode is preferable. By letting the client terminal devices 1 have the functions of the central server 3, one of the client terminal devices 1 as a host terminal device and the other client terminal devices 1 may be connected. Further, the shop servers 2 having the functions of the central server 3 may be connected to the client terminal devices 1 in the corresponding shops. Preferably, the shop servers 2 are provided between the central server 3 and the client terminal devices 1 and the central server 3, the shop servers 2 and the client terminal devices 1 are let to perform distributed processings as shown in FIG. 1. In this case, it is preferable to install the shop servers 2 in a one-to-one correspondence with the respective shops and to connect the client terminal devices 1 to the shop servers.
(E) Although the participation in the competition game is prohibited according to the cheater levels as a penalty to cheaters in the above embodiment, the participation in the game may be prohibited only for a specified period to a player who conducted an unauthorized operation.
(F) Besides the prohibition of the participation in the game, point assignment may be restricted, fewer points may be assigned or all or some of the points may be forfeited as a penalty to cheaters. Besides the points, item assignment may be restricted, fewer items may be assigned or all or some of the items may be forfeited. Further, the rank may be demoted or the title may be withdrawn or a specified handicap (e.g. reduction in the points of the chips) may be given for a competition game. These processes also lead to the suppression of unauthorized operations.
(G) The identification elements as a cheater are not limited to the rank and the points when a losing discard was made, and an element such as the place in the overall ranking may also be considered. In other types of games, it is possible to suitably adopt elements disadvantageous to players in view of the characteristics of these games. For example, in the case of a racing game, disadvantageous elements are thought to be goal finishing by another player or excess of a specified time. In these cases as well, an unauthorized end can be maximally prevented in the case where a game result disadvantageous to the player is expected. Cases where a game result disadvantageous to the player is expected are thought to be a case where the player is inferior to competing players and a case where the player is in a worse position than competing players in the middle of the game.
A game management method capable of executing a competition game among a plurality of game terminal devices by exchanging operation information with each other via a network as described above comprises a player identification step of identifying players before the start of the game, an unusual end judging step of judging that the game in process has been ended in an unusual manner, an unauthorized end judging step of judging whether or not the unusual end is an unauthorized end of the game due to an unauthorized operation by the player, and a cheat parameter calculating step of calculating a cheat parameter used to judge whether or not a specified penalty is to be given to the player having ended the game in an unauthorized manner.
Further, a game management system capable of executing a competition game among a plurality of game terminal devices by exchanging operation information with each other via a network comprises player identification means for identifying players before the start of the game; unusual end judging means for judging that the game in process has been ended in an unusual manner; unauthorized end judging means for judging whether or not the unusual end is an unauthorized end of the game due to an unauthorized operation by the player; and cheat parameter calculating means for calculating a cheat parameter used to judge whether or not a specified penalty is to be given to the player having ended the game in an unauthorized manner.
Furthermore, a game terminal device capable of executing a competition game by exchanging operation information via a network comprises player identification means for identifying a player before the start of the game; unusual end judging means for judging that the game in process has been ended in an unusual manner; unauthorized end judging means for judging whether or not the unusual end is an unauthorized end of the game due to an unauthorized operation by the player; and cheat parameter calculating means for calculating a cheat parameter used to judge whether or not a specified penalty is to be given to the player having ended the game in an unauthorized manner.
According to these constructions, if the players perform game operations in the respective plurality of game terminal devices, pieces of operation information are exchanged with each other via the network and the competition game is executed among the plurality of game terminal devices. The players are identified before the start of the game in the player identification step. If it is judged in the unusual end judging step that the game in process was ended in an unusual manner, it is judged in the unusual end judging step whether or not the unusual end is the unauthorized end of the game due to the unauthorized operation of the player and it is judged in the cheat parameter calculating step whether or not the specified penalty is to be given to the player having ended the game in an unauthorized manner. Accordingly, unauthorized operations of players can be suppressed and fairness can be maintained among honest players by judging with high accuracy whether or not the unusual end of the game was caused by the unauthorized operation of the player.
It is preferable that the unauthorized end judging step includes a step of setting cheat points based on a status of the competition game of the game terminal device operated by the player at the time of the unusual end; and the cheat parameter calculating step includes a step of accumulating the number of unusual ends, a step of adding the set cheat points to those Immediately before, and a step of calculating the cheat parameter from a ratio of the accumulated cheat points to the accumulated number of unusual ends. According to this construction, the cheat points are set based on the status of the competition game of the game terminal device operated by the player at the time of the unusual end, and the cheat parameter is calculated from the ratio of the accumulated cheat points to the accumulated number of unusual ends by executing the step of accumulating the number of unusual ends and the step of adding the set cheat points to those immediately before. In this way, unauthorized operations can be monitored with high probability.
The step of setting the cheat points is preferably performed based on the case where the player is inferior to the competing players in the competition game. Further, the step of setting the cheat points is preferably performed based on the case where the result of the competition game is worse than those of the competing players. According to these constructions, unauthorized operations can be monitored with high probability.
The step of setting the cheat points is preferably performed to assign cheat points that differ depending on the status of the competition game. According to this construction, cheating can be evaluated according to a degree of cheating, e.g. a cheat count and the status at the time of cheating.
Further, it is preferable to further comprise a penalty judging step of judging whether or not the cheat parameter has reached a threshold value as a criterion of the specified penalty. According to this construction, the penalty is given if the cheat parameter exceeds the threshold value, which leads to the suppression of unauthorized operations.
Furthermore, it is preferable to further comprise a penalty processing step of performing a specified penalty process if the player identified in the player identification step is a player judged to receive the specified penalty in the penalty judging step. According to this construction, the penalty is given to the player whose cheat parameter exceeded the threshold value, which leads to the suppression of unauthorized operations.
Further, the penalty processing step is preferably performed to give a specified handicap for the competition game. Alternatively, the penalty processing step is preferably performed to give a specified warning upon executing the competition game. According to these constructions, unauthorized operations are suppressed.
Furthermore, the penalty processing step is preferably performed to prohibit the execution of the competition game. According to this construction, unauthorized operations are suppressed and fairness is maintained among honest players.
Industrial Applicability
