[A: Embodiment]
[1. Outline of game system]
FIG. 1 is a block diagram illustrating a configuration example of a game system according to an embodiment of the present invention. As illustrated in FIG. 1, the game system 1 includes M game apparatuses 10-1 to 10-M (M is a natural number of 3 or more), a network NW, a matching server 20, and a management server 30. . The same game program is installed in the M game apparatuses 10-1 to 10-M.

  In the following description, when it is not necessary to distinguish the M game devices 10-1 to 10-M, they are simply referred to as game devices 10. In the present embodiment, a portable information terminal such as a smartphone, a tablet terminal, or a portable game machine is assumed as the game apparatus 10. However, any information processing apparatus can be adopted as the game apparatus 10. For example, the game apparatus 10 may be composed of a main body A and an information processing apparatus B as shown in FIG. In this case, the main body A is connected to the network NW via the information processing apparatus B. The game apparatus 10 may be, for example, a home game machine, a business game machine installed in a store or a play facility, or a terminal type information machine such as a personal computer.

The game executed on the game device 10 is, for example, a case where the user of the game device 10 operates the game device 10 to change the character that is the operation target of the user of the game device 10 into a virtual field F (“virtual” in the game). An example of “space”. Moreover, the character which is the operation object of another user can participate in this game.
In the following description, “participating in a game” means that there is a character that can be operated in the game, and is distinguished from simply watching a game. Participation includes joint battles that complete missions in cooperation with other users, and battles that compete with other users. In addition, the spectator can transmit a support message during the game watching. Spectators can participate in the game indirectly, but spectators cannot participate in the game.

  In the present embodiment, it is assumed that among the M game devices 10-1 to 10-M, a plurality of game devices 10 participate in the game, and one or a plurality of game devices 10 watch the game. The matching server 20 executes matching of the game apparatus 10 participating in the game and also executes matching of the game apparatus 10 watching the game. The game apparatus 10 wishing to participate in the game transmits a participation request to the matching server 20. In addition, the game device 10 that wishes to watch the game transmits a watch request to the matching server 20. Matching for participation is to determine a game device 10 participating in a certain game from among the game devices 10 that wish to participate in the battle. Matching for watching is to determine a game device 10 for watching a game from among the game devices 10 that want to watch.

  The management server 30 receives the result data Dx related to the result of the game from the game device 10 that has participated in the game, and receives the verification data Dy from the game device 10 that has watched the game. Then, it is determined whether the received result data Dx is a falsified game result.

The result data Dx includes one or more items. The plurality of items may be, for example, game wins and losses, items acquired in the game, items acquired in the game, parameters of characters, or points acquired in the game. Further, the result data Dx may be data for determining the outcome of the game or the items acquired in the game based on the progress of the game. An item is a game element for a character to advantageously advance a game in a virtual space. For example, a bomb and a fireproof suit correspond to the items. A parameter is a numerical value indicating the level of ability. For example, a numerical value indicating the defensive power of a character, a numerical value indicating the attack power of a bomb as an item, and the like are applicable.
The item of the collation data Dy matches the item of the result data Dx.

  The minimum configuration of the game system 1 in the present embodiment is a case where one game device 10 watches a game in which two game devices 10 participate. FIG. 3 is a block diagram showing a minimum configuration of the game system 1. In this figure, the first game device 10A, the second game device 10B, and the third game device 10C are included in the game devices 10-1 to 10-M shown in FIG. The first game device 10A and the third game device 10C surrounded by dotted lines are game devices 10 that participate in the game, and the second game device 10B is the game device 10 that watches the game.

  The first game device 10A transmits a battle request REQ1 to the matching server 20, the third game device 10C transmits a battle request REQ3 to the matching server 20, and the second game device 10B transmits a game request REQ2 to the matching server 20. . In this example, the matching server 20 designates the first game device 10A and the third game device 10C as game opponents, and designates the second game device 10B as the game device 10 for watching. The matching server 20 transmits a battle response RES1 to the first game device 10A, a battle response RES3 to the third game device 10C, and a watching response RES2 to the second game device 10B. The battle response RES1, the battle response RES3, and the watching response RES2 include information necessary for communication such as an IP address.

  When the game is executed in the first game apparatus 10A and the third game apparatus 10C, progress data Dp relating to the progress of the game is generated in each of the first game apparatus 10A and the third game apparatus 10C. The communication between the first game device 10A and the third game device 10C and the communication between the first game device 10A and the second game device 10B are directly communicated without going through the matching server 20 or the management server 30. The This communication is, for example, P2P (Peer to Peer) communication. In P2P communication, devices that have an equal relationship in communication are directly connected to each other to transmit and receive data.

  However, one of the participating game devices 10 functions as a host device, and the other game devices 10 and the watching game device 10 other than the host device among the participating game devices 10 function as client devices. . In this example, the first game device 10A corresponds to a host device, and the second game device 10B and the third game device 10C correspond to client devices.

The first game device 10A and the third game device 10C generate progress data Dp related to the progress of the game. The progress data Dp is data generated as the game progresses, and includes data necessary for game reproduction. Data necessary for reproducing the game includes data indicating a user's operation on the game device 10 or data indicating a change in the game element in accordance with the operation.
For example, when the user performs an operation of moving the character in the right direction, the data indicating the operation is data corresponding to the operation. Based on this data, a process of moving the character in the right direction is executed. As a result of the moving process, the character moves to the right. On the other hand, the data indicating the change of the game element according to the operation indicates, for example, the coordinates of the character after moving in the right direction in the above-described example. Based on this data, a process of moving the character from the current character position to the moved character position is executed. As a result, the character moves to the coordinates indicated by the data. The data indicating the change of the game element according to the operation includes the item installation status in addition to the character position described above. The item installation status corresponds to, for example, a position where an item (for example, a bomb) possessed by the character is installed.

  The first game device 10A transmits the progress data Dp generated by the first game device 10A to the third game device 10C using P2P communication. Conversely, the third game device 10C transmits the progress data Dp generated by the third game device 10C to the first game device 10A using P2P communication. Accordingly, the progress data Dp is shared between the first game apparatus 10A and the third game apparatus 10C. Therefore, the first game apparatus 10A and the third game apparatus 10C can execute the same game.

  In addition, the first game device 10 </ b> A functioning as a host device transmits result data Dx indicating a game result to the management server 30. Further, the first game device 10A generates progress data Dpp obtained by integrating the progress data Dp generated by the first game device 10A and the progress data Dp generated by the third game device 10C, and the integrated progress data Dp. Is transmitted to the second game apparatus 10B using P2P communication. In this case, since communication is performed without going through the management server 30, communication traffic of the management server 30 can be reduced.

  The second game device 10B receives the progress data Dpp generated by the first game device 10A, so that the game can be reproduced. The second game device 10 </ b> B reproduces the game based on the progress data Dpp, generates verification data Dy, and transmits the generated verification data Dy to the management server 30. The collation data Dy is used to determine whether the result data Dx is a falsified game result.

  Note that data transmission / reception between the first game apparatus 10 </ b> A and the third game apparatus 10 </ b> C may be executed via the matching server 20 or the management server 30. In this case, the matching server 20 or the management server 30 includes a transfer unit that transfers data. The transfer unit transfers the progress data Dp generated by the third game device 10C to the first game device 10A, and transfers the progress data Dp generated by the first game device 10A to the third game device 10C.

[2. Configuration of game device]
FIG. 4 is a block diagram illustrating a configuration example of the game apparatus 10. The game apparatus 10 is a computer system that includes a control device 11, a storage device 12, a display device 13, a communication device 14, and an input device 15. The control device 11 is a processor such as a CPU (Central Processing Unit) and comprehensively controls each element of the game device 10.

  The storage device 12 stores a program executed by the control device 11 and various data used by the control device 11. For example, the storage device 12 is configured by a known recording medium such as a magnetic recording medium or a semiconductor recording medium, or a combination of a plurality of types of recording media. The storage device 12 stores a game program PRg.

  The display device 13 displays an image under the control of the control device 11. For example, a flat display such as a liquid crystal display panel or an organic EL (Electroluminescence) display panel is used as the display device 13.

  The communication device 14 communicates with an external device via a network NW such as the Internet. For example, the communication device 14 can download the game program PRg from the server device. The downloaded game program PRg is stored in the storage device 12.

  The input device 15 outputs a signal corresponding to a user operation to the control device 11. The input device 15 may be a touch panel provided on the display panel of the display device 13, for example. Various buttons are displayed on the display panel, and when the user operates the touch panel, a signal corresponding to the user's operation is output to the control device 11.

  As described above, the game apparatus 10 functions not only as a terminal that participates in a game but also as a terminal that watches a game. In either case, the control device 11 is realized by executing the game program PRg stored in the storage device 12.

FIG. 5 is a functional block diagram illustrating functions of the game apparatus 10. The control device 11 executes the game program PRg stored in the storage device 12, thereby obtaining an acquisition unit 111, a display control unit 112, a collation data generation unit 113, a notification unit 114, a progress data generation unit 115, and result data It functions as the generation unit 116.
The acquisition unit 111 acquires the progress data Dpp from another game device 10 via the communication device 14 when the game device 10 is used for watching. In addition, when the game device 10 is used for a battle, the acquisition unit 111 acquires the progress data Dp from the other game devices 10 via the communication device 14.

When the game apparatus 10 is used for watching, the display control unit 112 causes the display device 13 to display a game screen reproduced for watching the game based on the progress data Dpp.
When the game device 10 is used for a battle, the display control unit 112 displays a game screen on the display device 13 based on the progress data Dp generated by the game device 10 and the progress data Dp acquired from the other game devices 10. To display.

  When the game device 10 is used for watching a game, the verification data generation unit 113 generates verification data Dy used for determining whether the result data Dx is data obtained by falsifying the game result based on the progress data Dpp. The generated result data Dx is transmitted to the management server 30 via the communication device 14.

  The notification unit 114 generates various notifications. The generated notification includes a message notification indicating a message such as an impression regarding the game during the watching game and an unauthorized notification indicating that an illegal act has been found. The dishonest act is an act that is not intended by the game creator to advance the game. For example, this is the case when the parameter indicating the character's ability is abnormal. The fraud notification is generated, for example, when the notification unit 114 detects that the user has pressed the report button for reporting the fraud displayed on the game screen based on the output signal of the input device 15. The fraud notification is transmitted to the management server 30 via the communication device 14.

Progress data generator 115 generates progress data Dpp when game device 10 is used as a host device. Further, when the game device 10 is used as a client device for participation in battle, progress data Dp is generated.
The result data generation unit 116 generates result data Dx.

  FIG. 6 shows an example of the game screen. In this example, it is assumed that the character C1 of the user U1 and the character C2 of the user U2 are competing in the field, and the user U3 and the user U4 are watching the game. It is assumed that the game screen is displayed on the game device 10 of the user U3. The avatar A3 shown at the lower left of the game screen is the user U3, and the avatar A4 is the user U4. In this example, “Kane”, which is the nickname of the user U3, is displayed at the top of the avatar A3, and “Akio”, which is the name of the user U4, is displayed at the top of the avatar A4.

In addition, a notification button B1 and an authorization button B2 are displayed at the lower right of the screen. When the user U3 finds an illegal act while watching the game, the user U3 presses the report button B1. In this case, the game device 10 of the user U3 transmits a fraud notification to the management server 30. Even if there is a fraud in a part other than the battle result, such as a fraud in the ability value of the character by the notification button B1, it is possible to increase the possibility of identifying other frauds by checking with the eyes of the spectator.
When the spectator recognizes that the game is normal, the authorization button B2 is pressed. In this case, a notification that there has been no fraud is transmitted from the game apparatus 10 to the management server 30.

FIG. 7 is a flowchart showing the operation of the game device 10 for watching. When the game apparatus 10 is used for watching games, the control apparatus 11 acquires the progress data Dpp from the external game apparatus 10 that outputs the progress data Dpp and the result data Dx (S1).
Next, based on the progress data Dpp, the control device 11 causes the display device to display a game screen reproduced for watching the game.
Next, the control device 11 generates collation data Dy based on the progress data, and transmits the collation data Dy to the management server 30.

[3. Matching server]
Next, the matching server 20 will be described. FIG. 8 is a block diagram illustrating a configuration example of the matching server 20. The matching server 20 includes a control device 21, a storage device 22, and a communication device 23. The control device 21 is a processor such as a CPU. The control device 21 comprehensively controls each element of the matching server 20.

  The storage device 22 stores a matching program PRm executed by the control device 21, a matching table TBLm, and various data. For example, the storage device 22 is configured by a known recording medium such as a magnetic recording medium or a semiconductor recording medium, or a combination of a plurality of types of recording media. The communication device 23 communicates with an external device via a network NW such as the Internet. Note that the storage device 22 is not necessarily provided in the matching server 20 and may exist outside the network NW for communication.

  FIG. 9 shows an example of the stored contents of the matching table TBLm. In the matching table TBLm, a battle ID for identifying the battle, a user ID indicating the battle player 1, a user ID indicating the battle player 2, and a user ID indicating the spectator are stored in association with each other. The user ID is identification information for identifying the user. In addition, when a plurality of opponents form a group and battle each other, the opponent 1 includes a plurality of user IDs, and the opponent 2 also includes a plurality of user IDs. Also, the number of spectators is not always one. When a plurality of users watch a game, a plurality of user IDs are included in the spectator. In the example shown in FIG. 9, in the game corresponding to the battle ID “F102”, the user with the user ID “SS001” and the user with the user ID “WQ587” battle each other, and the user with the user ID “ET302” watches the game. Is recorded in the matching table TBLm.

  FIG. 10 is a flowchart showing the contents of the matching process. First, when receiving a battle request via the communication device 23, the control device 21 starts matching processing (S11). The control device 21 specifies a battle condition included in the battle request (S13). The battle condition may include designation of a field to fight against or designation of an opponent.

  Thereafter, the control device 21 determines whether or not there is a game device 10 that matches the battle condition among the game devices whose opponents are not yet determined (S15). When it exists, the control apparatus 21 specifies the game apparatus 10 used as an opponent (S17). When there are a plurality of game devices 10 that satisfy the determination condition in step S15, the control device 21 randomly extracts the game devices 10 from the plurality of game devices 10, and identifies the extracted game devices 10 as opponents. . Alternatively, the control device 21 may specify the game device 10 as an opponent in descending order of time of receiving the battle request. When there is one game device 10 that satisfies the determination condition in step S15, the control device 21 identifies the game device 10 as an opponent.

  Next, the control device 21 transmits a battle response to the game device 10 serving as the host device, and transmits a battle response to the game device 10 serving as the client device (S19). The battle response transmitted from the control device 21 to the game device 10 serving as the host device includes designation of the host device and information necessary for communicating with the game device 10 serving as the client device. This information includes the IP address of the game apparatus 10 serving as the client apparatus. Note that the control device 21 may transmit a battle response only to the game device 10 serving as the host device, and may transmit a battle response from the game device 10 serving as the host device to the game device 10 serving as the client device.

  On the other hand, when the determination condition of step S15 is not satisfied, the control device 21 counts up the timer and starts measuring time (S21). Thereafter, the control device 21 determines whether or not a certain time has passed (S23). If the certain time has not elapsed, the control device 21 returns the process to step S15. When the predetermined time has elapsed, the control device 21 transmits a battle response indicating that the match is not established to the game device 10 that has received the battle request (S25), and ends the matching process.

  When the process of step S19 ends, the control device 21 determines whether or not there are a plurality of game devices whose observing targets are not yet determined (S27). When the determination result of step S27 is affirmative, the control device 21 randomly extracts game devices 10 for watching the game from the plurality of game devices 10 (S29). If the game devices 10 to be watched in this way are randomly extracted, even if the watching request is transmitted to the matching server 20, the game device 10 cannot specify which game is to be watched. Therefore, it is possible to prevent the opponent and the spectator from complicating and altering the game result.

  Thereafter, the control device 21 notifies the game device 10 serving as the host device of the game device 10 for watching the game (S31), and transmits a match-making watching response to the game device 10 that has transmitted the watching request. (S33). On the other hand, when the determination result of step S27 is negative, the control device 21 transmits a watching response for matching to the game device 10 that has transmitted the watching request (S35). In this way, the game apparatus 10 that has transmitted the watching request can know whether or not matching has been established.

  In this example, when there is one game device 10 that is not yet determined as a watching target, the determination result in step S27 is negative, and a watching response with no matching is sent to the watching request sender (S35). However, when the number of game apparatuses 10 is one and the determination result in step S27 is negative, the control apparatus 21 may advance the process to step S31 to establish matching. Alternatively, if there is one game device 10 and the determination result in step S27 is negative, the control device 21 starts counting up the timer, and watching the game even after a certain period of time, as in the match matching. When there is only one game device 10 whose target has not yet been determined, a watching response with no matching may be transmitted to the game device 10 that is the transmission source of the watching request.

[4. Management server]
Next, the management server 30 will be described. FIG. 11 is a block diagram illustrating a configuration example of the management server 30. The management server 30 includes a control device 31, a storage device 32, and a communication device 33. The control device 31 is a processor such as a CPU. The control device 31 comprehensively controls each element of the management server 30.

  The storage device 32 stores a control program PRc executed by the control device 31, a management table TBLc, and various data. For example, the storage device 32 is configured by a known recording medium such as a magnetic recording medium or a semiconductor recording medium, or a combination of a plurality of types of recording media. The communication device 33 communicates with an external device via a network NW such as the Internet. Note that the storage device 32 is not necessarily provided in the management server 30 and may exist outside the computer via the network NW.

  FIG. 12 shows an example of the contents stored in the management table TBLc. In the management table TBLc, management data Dc related to the game is stored in association with the user ID. The management data Dc may include a battle record, ranking, score, item, or point. “Battle record” is indicated by, for example, how many wins, how many losses or win rates. The “order” is an order indicating the strength of the user who plays the same game.

  FIG. 13 is a functional block diagram illustrating functions of the management server 30. The control device 31 functions as the determination unit 311, the management unit 312, and the reward granting unit 313 by executing the control program PRc stored in the storage device 32.

  As shown in FIG. 3, the first game device 10A participates in the game to generate progress data Dp and result data Dx, and the second game device 10B is used to watch the game. Based on the result data Dx output from the first game device 10A and the collation data Dy generated based on the progress data Dpp output from the first game device 10A in the second game device 10B. Then, it is determined whether the result data Dx is data obtained by falsifying the game result. More specifically, when the item of the result data Dx and the item of the collation data Dy do not match, it is determined that the game result has been falsified.

  Since the matching data Dy is generated based on the progress data Dpp in the second game device 10B watching the game, the determination unit 311 uses the first game for both watching the game and monitoring fraud. It can be determined whether the result data Dx generated by the device 10A has been tampered with.

  The management unit 312 manages the management data Dc in association with the user ID. Specifically, when the determination unit 311 determines that the result data Dx is data representing a game result, the management unit 312 reflects the result data Dx in the management data Dc. When it is not determined that the data represents the game result, the management unit 312 does not reflect the result data Dx in the management data Dc. Note that the data representing the game result is an example of data that is not a falsified game result.

Here, reflecting in the management data Dc means that the management unit 312 updates the management data Dc based on the result data Dx. Further, not reflecting the result data Dx in the management data Dc means that the storage content of the management table TBLc is not changed. Since the result data Dx relates to the result of the game, for example, the points included in the result data Dx are points acquired in the game. On the other hand, the point indicated by the management data Dc is a point currently owned by the user. Therefore, the management unit 312 adds a point indicated by the result data Dx to the point stored in the management table TBLc to generate a new point of the result data Dx.
According to the management unit 312, when the result data Dx is falsified due to fraud, the result data Dx generated by the first game device 10 </ b> A is not reflected in the management data Dc. Since it can be invalidated, fairness can be maintained among users.

  The reward granting unit 213 gives a reward corresponding to the user ID for identifying the user of the second game device 10B. The “reward” corresponds to what is valuable to the user. The “reward” may be one that can be used for the game, or may have an effect of making the game proceed advantageously. “Rewards” may include, for example, items, item or character parameters, points, and the right to participate in official matches. The parameter of the item or character may be changed temporarily or permanently so as to be advantageous to the user.

  When the game being watched is finished in the second game device 10B, the control device 11 of the second game device 10B transmits a verification notification including the verification data Dy and the user ID to the management server 30. When the management server 30 receives the verification notification, the reward granting unit 213 reads the management data Dc corresponding to the user ID included in the verification notification from the management table TBLc. Next, the reward granting unit 213 generates management data Dc in which the item of the management data Dc corresponding to the reward is changed, and stores the changed management data Dc in the management table TBLc in association with the user ID. For example, when the current point is “1000” and the reward is the point “100”, the reward granting unit 213 generates management data Dc indicating the point “1100”.

  In this way, in the second game device 10B, a game screen that reproduces the game in the first game device 10A is displayed, and collation data Dy is generated. The user of the second game apparatus 10B will watch the game executed on the first game apparatus 10A during the period of reproducing the game, and cannot play the game himself. In this embodiment, since reward is given to the user of the 2nd game device 10B, the incentive of watching a game can be raised.

[B: Modification]
Examples of specific modifications to the embodiment will be exemplified below. Two or more aspects arbitrarily selected from the following examples may be appropriately combined as long as they do not contradict each other.

[Modification 1]
In the above-described embodiment, as described with reference to FIG. 3, the first game device 10A participating in the game sends the progress data Dpp to the matching server 20 or the management server 30 to the second game device 10B watching the game. However, the present invention is not limited to this.
FIG. 14 is a block diagram illustrating a minimum configuration of the game system 1 according to the modification. FIG. 15 is a functional block diagram of the management server 30 according to the modification. The management server 30 according to Modification 1 includes a transfer unit 314 that transfers the progress data Dpp output from the first game device 10A to the second game device 10B.

  In the embodiment described above, since it is necessary to transmit the progress data Dpp from the first game device 10A to the second game device 10B, the first game device 10A knows the IP address of the second game device 10B. For this reason, there is a possibility that the first game apparatus 10 </ b> A impersonates the second game apparatus 10 </ b> B and transmits the collation data Dy to the management server 30. According to the first modification, the progress data Dpp is transferred to the second game device 10B via the management server 30. Accordingly, since the first game device 10A and the second game device 10B do not communicate directly, the first game device 10A cannot specify the IP address of the second game device 10B. Therefore, it is possible to prevent the first game device 10A from impersonating the second game device 10B and transmitting the verification data Dy to the management server 30. Therefore, compared with the case where the progress data Dpp is transmitted from the first game apparatus 10A to the second game apparatus 10B, the illegal act of the first game apparatus 10A can be reduced.

[Modification 2]
In the above-described embodiment, the determination unit 311 of the management server 30 determines that the game result has been tampered with when the items such as winning / losing and acquired points included in the result data Dx do not match the items included in the verification data Dy. However, the present invention is not limited to this.
The management server 30 acquires the collation data Dy from each of the game devices 10 that watch one or a plurality of games including the second game device 10B, and the determination unit 311 determines the result data Dx and the usage mode of the game Based on the number of pieces of verification data Dy, it may be determined whether the result data Dx is data that has not altered the game result. According to this modification, since the alteration of the game result is determined based on the result data and the number of collation data corresponding to the usage mode of the game, in order to detect fraud depending on the importance of the game It is possible to set the number of game devices required for watching. Further, in a game where fraud does not become a big problem, it is possible to reduce excessive fraud prevention that prevents the game from proceeding because spectators do not gather.

The “game usage mode” may be, for example, a “game opponent” using a game. For example, in the case of a battle between friends, the number of game devices for watching may be reduced as compared to the case of a battle with an unknown stranger.
Further, the “game usage mode” may be, for example, “reward contents set for the game”. The reward content may include, for example, whether there is a cash reward, or whether the reward points are a certain value or more. By setting the number of game devices for watching according to the reward contents, the number of game devices for watching is increased when there are many rewards compared to when there are few rewards, and there is no falsification of the game results Can be determined more strictly.

  Further, the “game usage mode” may be, for example, “the influence of the game on the rank with other users”. The ranking may include, for example, a user ranking or a user rating. By setting the number of game devices for watching according to the influence on the ranking, if the influence on the ranking is large, the number of game devices for watching is increased compared to the case where the influence on the ranking is small, and the result of the game It can be determined more strictly that there is no tampering.

  Further, the “game usage mode” may be, for example, “whether or not the game is designated by the organizer (operator)”. In online games, game organizers may hold official games. For example, esports corresponds to such an official game. By setting the number of watching game devices according to whether or not the game is designated by the organizer, for example, the official game increases the number of watching game devices compared to the informal game, and the result of the game It can be determined more strictly that there is no falsification. Note that the number of game devices for watching may be increased in the official game winning decision game as compared to the first game.

[Modification 3]
In addition, the determination unit 311 may determine whether the result data Dx is data that has not altered the game result based on one or more determination items according to the usage mode of the game. According to this modification, the processing load of the determination unit can be changed according to the usage mode of the game. In addition, in a game where fraud does not become a big problem, it is possible to reduce excessive fraud prevention that prevents the game from proceeding because spectators do not gather.

  The “one or more determination items according to the game usage mode” may be determined in advance according to the usage mode, or the number of determination items may be predetermined according to the usage mode. The determination unit 311 may specify one or more determination items according to the number of determination items. When specifying one or a plurality of determination items according to the number of determination items, the determination unit 311 may randomly extract the determination items by the number of determination items, or the number of determination items in a predetermined order. Only the determination item may be specified.

  More specifically, the determination unit 311 determines one or a plurality of determination items, and when the result data Dx matches the verification data Dy for the determined determination item or items, the result data Dx is the game It may be determined that the result is data that has not been tampered with.

When the game usage mode is, for example, “game opponent”, in the case of a battle between friends, the number of determination items may be reduced as compared to the case of a battle with an unknown stranger.
In addition, when the usage mode of the game is, for example, “the reward content set for the game”, by setting a determination item according to the reward content, when the reward is large, it is compared with the case where the reward is small. By increasing the number of determination items, it can be determined more strictly that there is no falsification of the game result.
In addition, when the usage mode of the game is, for example, “the influence of the game on the rank with other users”, when the influence on the rank is large, the number of determination items is increased compared to the case where the influence on the rank is small, It can be determined more strictly that there is no falsification of the game result.
Further, when the usage mode of the game is, for example, “whether or not the game is designated by the organizer (operator)”, by setting the determination item according to whether or not the game is designated by the organizer, for example, In the official game, the number of determination items is increased as compared with the unofficial game, and it can be determined more strictly that there is no falsification of the game result. In addition, you may increase the number of determination items in the championship decision game of an official game compared with a 1st game.

[Modification 4]
In the embodiment described above, the game is premised on a plurality of game apparatuses 10 participating, but the present invention is not limited to this. That is, a game executed only by the first game device 10A may be watched by the second game device 10B. That is, the third game apparatus 10C may not be provided.

[Modification 5]
In the embodiment described above, the matching server 20 and the management server 30 are provided separately, but the present invention is not limited to this, and the matching server 20 and the management server 30 may be integrated.

[Modification 6]
In the above-described embodiment, the matching of the battle in the matching server 20 is determined in consideration of the battle condition, but the present invention is not limited to this. For example, you may identify the game apparatus 10 which becomes an opponent at random from the several game apparatus 10 with which an opponent is undetermined. Or you may match the user of a close class on a fixed reference | standard.

[Modification 7]
In the above-described embodiment, the result data Dx is transmitted from the host device to the management server 30 among the plurality of game devices 10 participating in the game, but the present invention is not limited to this. The result data Dx may be transmitted to the management server 30 from the game device 10 that has participated in a game other than the host device. The management server 30 may determine whether the game result has been tampered with using the plurality of result data Dx and the collation data Dy.

[Modification 8]
In the above-described embodiment, the match of watching games is executed immediately after the matching of entering battles, but the present invention is not limited to this. In the match of watching games, watching games may be permitted for games that have already been played.

[Modification 9]
In the above-described game screen (FIG. 6), the avatars A3 and A4 of the spectators and the names and nicknames of the spectators are displayed, but these may be hidden. This makes it difficult for the participant to specify the spectator, so that it is possible to increase the difficulty of impersonating the spectator and tampering with the game results.
The avatar of the spectator may be displayed on the game device 10 of the spectator and may be hidden on the game device 10 of the opponent. In this case, since it becomes impossible to specify the spectator by the avatar, it is possible to further increase the difficulty of falsifying the game result as compared to the case of displaying the avatar.

[Modification 10]
In the embodiment described above, the result data Dx received by the management server 30 from the first game device 10A relates to the game result, and the collation data Dy has the same contents as the result data Dx. The present invention is not limited to this, and the data for determining falsification of the game result may be information generated on the same basis in the plurality of game apparatuses 10. Therefore, it may be information on the progress of the game or data generated during the progress of the game. In short, any information that is unique to the game may be used.
It may also be encrypted information.

  Further, the management server 30 may set for each battle ID the criteria for generating the result data Dx and the collation data Dy, that is, what determination items are included in the result data Dx and the collation data Dy. The possibility of analyzing the result data Dx and the collation data Dy can be lowered by having a plurality of generation criteria and setting each match. As a data generation standard, for example, a point value acquired in a battle may be used, or the number of items used may be used.

[Modification 11]
In the embodiment described above, the result data Dx and the collation data Dy do not need to be exactly the same data as long as collation is possible. For example, the data may be encrypted using data determined for each of the game devices 10-1 to 10-M. For example, encryption may be performed using the IP address of the game apparatus 10 or the battle ID. If the data is different for each of the game apparatuses 10-1 to 10-M, the difficulty of analysis increases, so that it is possible to further reduce fraud.

[Modification 12]
The management server 30 may acquire the result data Dx from the plurality of game devices 10 participating in the game and may acquire the collation data Dy from the plurality of game devices 10 watching the game. In this case, it may be determined by majority decision in determining whether the game result is falsified.
For example, data abnormalities due to communication failures such as packet loss may occur rarely. For this reason, it may be determined that there is no falsification of the game result if there is a certain number or less of data that may be fraudulent.

[Modification 13]
In the embodiment described above, if the match of the match is established, the game is started even if the match of the match is not established. However, the present invention is not limited to this, and according to the use mode of the game, May be required. For example, in a big tournament such as an official game of an online game or a battle in which a large reward is applied, a spectator may be essential from the viewpoint of fraud prevention.

[Modification 14]
In the embodiment described above, the host device is determined from among the game devices 10 participating in the game, but the present invention is not limited to this. The game device 10 for watching a game may be a host device, and all the game devices 10 for a battle may be client devices. By using the game device 10 that does not participate as a host device as a host device, it is possible to reduce a difference in communication delay between the game devices 10 due to a difference between the host and the client, and to maintain fairness between the opponent terminals.

[Modification 15]
In the embodiment described above, the watching request may be automated. For example, in the game apparatus 10, when the user sets an automatic watching request, it is possible to watch one after another without operating the watching request, and it is possible to transmit the verification data Dy for each battle. When an automatic watching request is set and left unchecked, the collation data Dy is frequently generated, so that the shortage of watching people can be reduced.

[Modification 16]
In the embodiment described above, the spectator could not designate the battle to watch, but the present invention is not limited to this. It may be possible to specify the battles to watch to some extent. It is also possible to specify an opponent's profile, an opponent's level, etc., and to make it possible to watch matches that meet the conditions. In this case, when searching for a match to be watched, the effectiveness of the determination of the collation data Dy of the spectator may be lowered as the search condition is such that the opponent is more easily identified. Decreasing the effectiveness means that two or more pieces of matching data Dy are required where one piece of matching data Dy is usually sufficient.

[Modification 17]
In the embodiment described above, a device ID for identifying [0] the game device 10 may be used instead of the user ID. When the device ID is used, the user ID associated with the device ID may be specified by the device ID. For example, when a certain user has two game apparatuses 10, the results of the games executed on the respective game apparatuses 10 can be integrated in the management server 30.

[C: Appendix]
From the above description, for example, a preferred aspect of the present invention is grasped as follows. In addition, in order to facilitate understanding of each aspect, the following description is not intended to limit the present invention to the illustrated aspect.

[Aspect 1]
The management server program according to a preferred aspect (aspect 1) of the present invention includes a first game device (10A) for generating progress data (Dpp) relating to game progress and result data (Dx) relating to the result of the game; A program of a management server (30) that is communicable with a second game device (10B) for watching the game and includes a processor, and outputs the processor (31) from the first game device (10A). And the collation data (Dy) generated based on the progress data (Dpp) output from the first game device (10A) in the second game device (10B). Based on this, the result data (Dx) is made to function as a determination unit (311) for determining whether the result of the game is falsified.
According to the above aspect, since the second game device for watching the game generates the collation data based on the progress data, the first game device can be used for both watching the game and monitoring fraud. It can be determined whether the generated result data has been tampered with.

  The “progress data relating to the progress of the game” may be any data as long as it is generated as the game progresses, and includes data necessary for reproducing the game. Data necessary for reproducing the game may include data indicating a user's operation on the first game device or data indicating a change in the game element according to the operation. For example, when the user performs an operation of moving the character in the right direction, the data indicating the operation is data corresponding to the operation. Based on this data, a process of moving the character in the right direction is executed. As a result of the moving process, the character moves to the right. On the other hand, the data indicating the change of the game element according to the operation indicates, for example, the coordinates of the character after moving in the right direction in the above-described example. Based on this data, a process of moving the character from the current character position to the moved character position is executed. As a result, the character moves to the coordinates indicated by the data. The data indicating the change of the game element according to the operation includes the item installation status in addition to the character position described above. The item installation status corresponds to, for example, a position where an item (for example, a bomb) possessed by the character is installed.

The “result data relating to the game result” may be any data as long as it is related to the game result. The result data may include, for example, game wins and losses, items acquired in the game, parameters of items or characters acquired in the game, or points acquired in the game. Furthermore, the result data may be data for determining a game win or loss or an item acquired in the game based on the progress of the game.
An “item” is a game element for a character to advantageously advance a game in a virtual space. For example, a weapon in a battle game or a car part in a car racing game is applicable. “Point” is an exchange value used for purchasing an item in a game, and corresponds to a so-called in-game currency.
The “collation data” may be any data as long as it contributes to confirming the validity of the result data. The verification data may include, for example, game wins and losses, items acquired in the game, parameters of items or characters acquired in the game, or points acquired in the game. In addition, some or all of the items of the collation data may be the same as the items of the result data.
The “result data” may include, for example, data that correctly represents the result of the game generated inside the first game device, or data obtained by changing data that is a duplicate of the data. In this case, the determination unit determines whether the changed data (result data) is data obtained by falsifying the game result.
In addition, the “first game device” may be a game device main body, or may be an information processing device that falsifies result data provided in the game device main body and the subsequent stage of the game device main body. In this case, data obtained by correctly changing the data that correctly represents the game result in the information processing apparatus (B) using the data that correctly represents the game result output from the game apparatus main body (A) is “result data”. (See FIG. 2). The determination unit determines whether the changed data (result data) is data obtained by falsifying the game result.

[Aspect 2]
In a preferred example of aspect 1 (aspect 2), the game is executed on the first game device (10A) and the third game device (10C), and the progress data is passed through the management server (30). Rather, it is transmitted and received between the first game device (10A) and the third game device (10C). According to the above aspect, since the progress data is transmitted and received between the first game device and the third game device without going through the management server, the communication traffic of the management server can be reduced.

  “Transmitted / received between the first game device and the third game device without going through the management server” corresponds to transmission / reception of data by P2P (Peer to Peer) connection, for example. The “game” is typically a battle game. In the battle game, a character that operates in accordance with the operation of the user of the first game device and a character that operates in accordance with the operation of the user of the third game device may battle each other.

[Aspect 3]
In a preferred example (Aspect 3) of Aspect 1 or Aspect 2, the second game device (10B) is a game device (10) randomly extracted from a plurality of game devices (10). According to the above aspect, since the second game device is randomly extracted, it is possible to reduce the fact that the user of the first game device and the user of the second game device collide to falsify the game result.

[Aspect 4]
In a preferred example (Aspect 4) of Aspect 1 to Aspect 3, the management server receives the verification data from each of the game devices (10) watching the one or more games including the second game device (10B). (Dy) is acquired, and the determination unit (311) determines that the result data is the game based on the result data (Dx) and the number of the matching data (Dy) according to the usage mode of the game. It is determined that the result is data that has not been falsified. According to the above aspect, the alteration of the game result is determined based on the number of collation data and the result data according to the game usage mode, so that the cheating is detected according to the importance of the game. It is possible to set the number of game devices required for watching.
For example, in an official game in which the game usage mode provides a large reward compared to a normal battle, the number of game devices for watching can be increased compared to a normal battle. As a result, in the official game, the reliability of the result data can be improved under the supervision of many spectators as compared to the normal game.

The “game usage mode” may be, for example, a “game opponent” using a game. For example, in the case of a battle between friends, the number of game devices for watching may be reduced as compared to the case of a battle with an unknown stranger.
Further, the “game usage mode” may be, for example, “reward contents set for the game”. The reward content may include, for example, whether there is a cash reward, or whether the reward points are a certain value or more. By setting judgment items according to the reward content, if there are many rewards, the number of game devices for watching will be increased compared to when there are few rewards, and there will be no stricter alteration of the game results. Can be determined.
Further, the “game usage mode” may be, for example, “the influence of the game on the rank with other users”. The ranking may include, for example, a user ranking or a user rating. By setting judgment items according to the influence on the order, when the influence on the order is large, the number of game devices for watching is increased compared to the case where the influence on the order is small, and the game result is not falsified. Can be determined more strictly.
Further, the “game usage mode” may be, for example, “whether or not the game is designated by the organizer (operator)”. In online games, game organizers may hold official games. For example, esports corresponds to such an official game. By setting judgment items according to whether or not the game is designated by the organizer, for example, official games will increase the number of game devices for watching compared to informal games, and there will be no falsification of game results Can be judged more strictly. Note that the number of game devices for watching may be increased in the official game winning decision game as compared to the first game.

[Aspect 5]
In a preferred example (Aspect 5) of Aspect 1 to Aspect 4, the processor (31) further manages management data (Dc) related to the game in association with identification information for identifying the user. When the determination unit (311) determines that the result data (Dx) is data representing the result of the game, the management unit (312) converts the result data (Dx) into the management data. If the result data (Dx) is not determined by the determination unit (311) to represent the game result, the management unit (312) reflects the result data (Dx). Is not reflected in the management data (Dc). According to the above aspect, when the result data is falsified by fraud, the result data generated by the first game device is not reflected in the management data. Therefore, when the result data is falsified, the game can be invalidated.

  “Management data” may include a battle record, ranking, score, item, or point. “Battle record” is indicated by, for example, how many wins, how many losses or win rates. The “order” is an order indicating the strength of the user who plays the same game.

[Aspect 6]
In a preferred example (Aspect 6) of Aspect 1 to Aspect 5, the processor (31) further grants a reward corresponding to identification information for identifying a user of the second game device (10B). Function as a section (313). According to the above aspect, in the second game device, the game screen that reproduces the game in the first game device is displayed, and collation data is generated. The user of the second game device watches the game executed on the first game device during the period of reproducing the game, and cannot play the game himself. According to this aspect, since the reward is given to the user of the second game device, the incentive for watching the game can be increased.

  The “reward” corresponds to what is valuable to the user. “Rewards” may include, for example, items, item or character parameters, points, and the right to participate in official matches. The parameter of the item or character may be changed temporarily or permanently so as to be advantageous to the user.

[Aspect 7]
In a preferred example (Aspect 7) of Aspect 1 to Aspect 6, the processor (31) further outputs the progress data (Dpp) output from the first game apparatus (10A) to the second game apparatus (10B). The progress data is not directly communicated between the first game device (10A) and the second game device (10B). According to the above aspect, when transmitting progress data from the first game device to the second game device without going through the management server, the first game device knows the address of the second game device. For this reason, there is a possibility that the first game device impersonates the second game device and transmits the verification data to the management server. According to this aspect, since the progress data generated by the first game device is transferred to the second game device via the management server, the first game device cannot specify the address of the second game device. Therefore, since it is possible to prevent the first game device from impersonating the second game device and transmitting the verification data to the management server, the first game device can be compared with the case where the progress data is transmitted from the first game device to the second game device. It is possible to reduce fraud in one game device.

[Aspect 8]
The management server which concerns on the suitable aspect (aspect 8) of this invention communicates with the 2nd game device which observes the 1st game device which produces | generates the progress data regarding the progress of a game, and the result data regarding the result of the said game. A management server that is capable of: the result data output from the first game device; and the verification data generated based on the progress data output from the first game device in the second game device; A determination unit for determining whether the result data is data obtained by falsifying the game result.

[Aspect 9]
A game system (1) according to a preferred aspect (aspect 9) of the present invention includes a first game device (10A) that generates progress data (Dpp) relating to the progress of a game and result data (Dx) relating to the result of the game; The second game device (10B) for watching the game, the result data (Dx) output from the first game device (10A), and the first game device ( Management for determining whether the result data (Dx) is data obtained by falsifying the game result based on the collation data (Dy) generated based on the progress data (Dpp) output from 10A) And a server (30).

[Aspect 10]
A game device program according to a preferred aspect (aspect 10) of the present invention is a program of a game device (10B) including a processor (11), and the processor (11) stores progress data ( Dpp) and an acquisition unit (111) that acquires the progress data (Dpp) output from the external game device (10A) that generates the result data (Dx) related to the game result, and the progress data (Dpp) Based on the display control unit (112) for displaying the game screen reproduced for watching the game on the display device (13) and the progress data (Dpp), the result game (Dx) displays the result of the game. It is made to function as a collation data generation part (113) which produces | generates the collation data (Dy) used for determination whether it is falsified data. According to the above aspect, the game screen that reproduces the game based on the progress data is displayed on the display device, so that the game of the external game device can be watched, and the verification data is generated based on the progress data. Therefore, the game device used for watching the game can be used to determine whether the game result has been tampered with.
“Watching” refers to watching a reproduced game without participating in the game as a player. Therefore, “reproduce to watch the game” means reproduction of the game that does not affect the result data.

[Aspect 11]
The game device of aspect 10 obtains the progress data (Dpp) output by the external game device (10A) that generates progress data (Dpp) relating to the progress of the game and result data (Dx) relating to the result of the game.
