And determining whether or not the game data corresponding to the selection information matches among all the game terminals. If they match, the selection is made to the game control means of each of the plurality of game terminals. Management means that permits the use of game data corresponding to the information and prevents the use of the game data corresponding to the selection information if they do not match (S106 to S109) S305 to S309) are provided.

  In the game system of the present invention, when the data selection means of the parent device selects data, the selection information is notified to each game terminal. In each of the parent device and the child device, the collation information is acquired based on the game data corresponding to the selection information recorded in its own storage device, and the collation information is provided from the collation request device to the collation execution device. In the collation execution device, the collation information corresponding to its own game data and the collation information provided from the collation requesting device are collated to determine the consistency of the game data. Based on the determination result, it is determined whether or not the game data corresponding to the selection information matches among all the game terminals, and if it is determined that they match, the game data corresponding to the selection information is a plurality of game terminals. The game progresses by being used in common. If the game data corresponding to the selection information does not match between the game terminals, the use of the game data is blocked. Therefore, it is possible to advance the game while guaranteeing the consistency of the game data.

[First embodiment]
A game system according to one embodiment of the present invention is shown in FIG. In the game system 1, a plurality of game machines (corresponding to game terminals) 2 and a center server 3 are respectively connected to a network 5 via a router 4. The center server 3 is not limited to an example constituted by one physical device, and one logical center server 3 may be constituted by a server group as a plurality of physical devices. Furthermore, one game machine 2 may be used as the center server 3. The network 5 implements network communication using the TCP / IP protocol. Typically, the Internet is used as the network 5. Each game machine 2 is configured as a business or commercial game terminal that collects a play fee as a price for the game. An appropriate number of game machines 2 are installed in a commercial facility such as a store 6. The router 4 is installed in association with each store 6 and the center server 3, and the game machines 2 in the same store are connected to the network 5 via the common router 4. A local server may be installed between the game machine 2 and the router 4 of the store 6, and the game machine 2 may be communicably connected to the center server 3 via the local server.

  The center server 3 is installed by an operator of the game system 1 and provides various services via the network 5 to the game machine 2 or a user (player) of the game machine 2. As an example, the center server 3 authenticates a game program or data update service via the game machine 2, a user of the game machine 2, and plays data including the play history, save data, etc. of the user on the center server 3. And a matching service between the users when the users play against each other or cooperate with each other via the network 5.

  The game machine 2 and the center server 3 have unique IP addresses for identifying them on the network 5. In communication between the game machines 2 or between the game machine 2 and the center server 3, a communication partner is specified using the IP address. When the network 5 is a public network such as the Internet, a unique fixed address on the network 5 is set for each router 4. In the game machine 2, a private address for uniquely identifying the game machine 2 on the network 5 is set as an IP address in combination with the fixed address. In this case, a virtual private network (VPN) is constructed between the game machine 2 and the center server 3 or between the game machines 2, and each game machine 2 is uniquely identified using a private address on the VPN. Is done.

  FIG. 2 shows the basic contents of a quiz game executed in the game system 1. In this example, when the N game machines 2 are matched and grouped by the center server 3, one of the game machines 2 is the parent machine A, and the other game machine 2 is the child machine B, Each of them is set as C,... N, and a network connection between the game machines 2 is established. The two games are provided with a plurality of quiz data in which quiz questions and answers are recorded in advance in association with question IDs. The quiz data to be used in the quiz game is selected by the parent device 2, and the problem ID of the selected quiz data is given to the child devices B, C,. The parent device A and the child devices B, C,... N identify the problem to be asked by referring to the quiz data corresponding to the problem ID, and present the problem to the players A, B, C,. Ask for. When the players A, B, C,... N answer, the correctness of the answer is determined by each of the master device A and the slave devices B, C,... N, and the correctness determination result of the slave devices B, C,. Sent to machine A. Instead of or in addition to the result of the correctness determination, the answer itself may be encoded and transmitted from the slave units B, C,... N to the master unit A. Thereby, the answer status of each player with respect to the problem is collected in the parent device A, and processing such as calculation of the correct answer rate or sharing of answer contents of each player is enabled. A predetermined number of questions are presented sequentially, and the correctness of the answers is counted for each player, so that the results (correct answer rate, etc.) for each player are competed. Furthermore, in the game system 1, a plurality of players cooperate to complete an answer for one question, or a problem with a plurality of answers is given to all players to compete for a match of answers. A cooperative play in which the cooperation of the player is added to the elements of the game is also possible. An example of the game screen in the former case is shown in FIG. 3, and an example of the game screen in the latter case is shown in FIG. In the example of FIG. 3, the problem that the four alphabet letters (“CAKE” as an example) are correct is given, and each of the four players is required to answer one of the four letters. FIG. 3 shows a state in which the characters “C”, “B” by player A, “K” by player C, and “E” by player D are input as answers. When the answer is completed, points are awarded to the four players. In the example of FIG. 4, as the same answer is increased, the score given to the four players becomes higher. FIG. 4 shows a state in which the players A, B, and C have input “USA” and the player D has input “Russia” as answers. In this case, the answers of the three players match. A score is given to the players A to D.

  Next, with reference to FIG. 5, the structure of the game machine 2 for implement | achieving the quiz game mentioned above is demonstrated. Each game machine 2 has a common configuration, but the logical configuration differs depending on whether it functions as a parent machine or a child machine. (Only one unit is shown as a representative.) As shown in FIG. 5, each game machine 2 is provided with a control unit 10. The control unit 10 includes a microprocessor, a ROM in which a program such as an operating system to be executed by the microprocessor is recorded, and an internal storage device (not shown) such as a RAM that provides a work area for the microprocessor. A computer unit provided.

  An input device 11, a display device 12, and a storage device 13 are connected to the control unit 10. The input device 11 receives a player's operation and outputs a signal corresponding to the operation content to the control unit 10. In order to enable an answer by an arbitrary character string or numerical value, the input device 11 includes an input means capable of inputting characters and numerical values, such as a keyboard and a handwritten tablet device. The display device 12 displays a game screen or the like in accordance with instructions from the control unit 10. The storage device 13 is an appropriate combination of a non-volatile storage medium that can store data such as a ROM or a hard disk storage device and a semiconductor memory that provides a temporary work area to the control unit 10 such as a RAM. Composed. The storage device 13 stores various data such as a game program 101 to be executed by the control unit 10 and a quiz data table 102 referred to by the program 101.

  As shown in FIG. 6, the quiz data table 102 is configured as a set of a plurality of quiz data (corresponding to game data) Qd. One quiz data Qd has a data structure in which a question of a quiz and the content of an answer are described in association with a unique question ID for each data Qd. The question and the answer may be configured by appropriately combining character strings, images, and the like. The answer content data Qd also includes answer options displayed together with the answer. Although illustration is omitted, the quiz data Qd may include information specifying the genre of the problem, the difficulty level, and the like as information when selecting the problem.

  In the game machine 2 as the parent machine, the control unit 10 reads and executes the game program 101, so that the question selection unit 15, the hash value calculation unit 16, and the collation unit as logical devices are provided inside the control unit 10. 17 is generated. The question selection unit 15 selects the quiz data to be used in the quiz from the quiz data table 102 in response to the selection condition, and outputs the problem ID of the selected quiz data Qd. The problem ID of the quiz data Qd selected by the question selection unit 15 is given to the game machine 2 as a child machine, so that the quiz data Qd common to all the game machines 2 is selected and the same problem is given to the player. Will be asked.

  However, when the quiz data Qd of some game machines 2 is updated and the quiz data Qd of other game machines 2 is not updated, the problem and the answer are not found even if the problem IDs match between the game machines 2. May be different. In order to prevent such inconsistency of the quiz data Qd, a hash value calculation unit 16 and a collation unit 17 are provided. The hash value calculation unit 16 inputs quiz data Qd to a predetermined hash function, calculates a hash value, and outputs the calculation result. The hash value is a fixed-length numeric string calculated according to a predetermined algorithm in order to verify the consistency of electronic data. Since the probability that the same hash value is obtained even though the input electronic data is different is extremely small, the hash value can be handled as verification information that is substantially calculated for each quiz data Qd. The collation unit 17 collates the given two hash values and outputs the collation result. On the other hand, in the game machine 2 as a child machine, the question selection unit 15 and the collation unit 17 are omitted, and the hash value calculation unit 16 is generated as a logical device inside the control unit 10. In addition to the illustrated logical devices, various logical devices are generated in the control unit 10, but these are not shown.

  When the parent machine and the child machine are determined between the game machines 2 matched by the center server 3 and the environment for starting the quiz game is prepared, the control unit 10 of each game machine 2 advances the game. The quiz game is started in a predetermined procedure in accordance with an instruction from the control unit 10 of the parent machine. The matching procedure and the basic progress control of the quiz game may be the same as those of a known multiplayer quiz game system, and description thereof is omitted here. The game system 1 according to the present embodiment is characterized in that processing for confirming the consistency of the quiz data Qd is performed between the parent device and the child device when a question is given. Hereinafter, the description will be continued with a focus on processing related to confirmation of consistency of the quiz data Qd.

  FIG. 7 shows an outline of processing performed between the parent machine and the child game machine 2 in order to confirm the consistency of the quiz data Qd. First, when a question ID is selected by the question selection unit 15 of the parent device, the parent device gives the quiz data Qd corresponding to the question ID in the quiz data table 102 held by the parent device to the hash value calculation unit 16. A hash value corresponding to the quiz data Qd is calculated. The problem ID is given to all the slave units as selection information in parallel. In each slave unit, the quiz data Qd corresponding to the problem ID is specified from the quiz data table 102 held by itself, and the quiz data Qd is given to the hash value calculation unit 16 to calculate the hash value corresponding to the quiz data Qd. Is done. The hash value calculated by the slave unit is sent to the master unit. In the parent device, the collation unit 17 collates the hash value calculated by itself with the hash value sent from each child device. If all hash values match, the quiz data Qd corresponding to the problem ID is consistent. In this case, a question is permitted from the parent device to each child device, and the parent device and the child device ask questions of the quiz data Qd corresponding to the problem ID. On the other hand, if at least one hash value does not match, the consistency of the quiz data Qd between the game machines 2 is not secured, so the problem ID is discarded and a new problem ID is displayed in the question selection unit 15. Is selected.

  FIG. 8 shows a question control routine executed by the control unit 10 of each game machine 2 of the parent machine and the child machine in order to realize the above-described processing. These routines are executed prior to a question when a question is given in a quiz game. First, the control unit 10 of the parent machine selects a problem using the question selection unit 15 in step S101, and transmits the problem ID to the game machine 2 of the child machine in the subsequent step S102. In the next step S103, the control unit 10 of the parent device gives the quiz data Qd specified by the selected problem ID to the hash value calculator 16 to calculate the hash value. Thereafter, the control unit 10 of the parent device proceeds to step S104 and acquires a hash value from the child device.

  On the other hand, the control unit 10 of each slave unit acquires the problem ID transmitted from the master unit in step S201. In subsequent step S202, the control unit 10 of the child device acquires the quiz data Qd corresponding to the problem ID from the quiz data table 102 recorded in the storage device 13 of the own device, and calculates the hash value of the data Qd. A hash value is calculated by giving to the unit 16. Thereafter, the control unit 10 of each child device proceeds to step S203 and transmits the calculated hash value to the game device 2 of the parent device.

  When the hash values are acquired from all the slave units in step S104, the control unit 10 of the master unit proceeds to step S105 and uses the collation unit 17 to calculate the hash value calculated by itself in each slave unit. To match. In subsequent step S106, the control unit 10 of the parent device determines whether or not all hash values match. If all the hash values match, the control unit 10 of the parent device proceeds to step S107 to notify all the child devices of permission of the question. In subsequent step S108, the control unit 10 of the parent device permits the question to be given to the own device, thereby completing the question control routine. On the other hand, if at least one hash value does not match another hash value in step S106, the control unit 10 of the parent device proceeds to step S109 to notify each child device that the question cannot be given, and then Returning to step S101, a new problem is selected.

  When permission or disapproval of the question is notified as a result of the collation determination in step S107 or step S109, the control unit 10 of the slave unit acquires the notification content in step S204, and whether or not the question permission is notified in the subsequent step S205. Is determined. When it is notified that the question cannot be given, the slave unit control unit 10 discards the previously notified problem ID, returns to step S201, and waits for a notification of a new problem ID. If the question permission is notified in step S205, the control unit 10 of the child device proceeds to step S206, permits the question to the own device, and then ends the question control routine.

  Through the above processing, a common problem ID is given to each game machine 2, and each game machine 2 calculates a hash value of the quiz data Qd corresponding to the problem ID held in the storage device 13 of its own machine. Only when all the calculated hash values match, the questions based on the quiz data Qd corresponding to the problem ID are permitted. When the question is permitted, each game machine 2 issues a question of the quiz data Qd corresponding to the question ID, and whether the answer to the question is correct or not is collected in the game machine 2 as the parent machine. Then, a predetermined answer process is performed. Therefore, it is possible to advance the quiz game while ensuring the consistency of the quiz data Qd between the game machines 2.

  In the above embodiment, the control unit 10 corresponds to the game control means, and the hash value calculation unit 16 as a logical device generated therein corresponds to the collation information acquisition means. Further, the game machine 2 as the parent device corresponds to the verification execution device, and the game machine 2 as the child device corresponds to the verification request device. Then, the control unit 10 of the game machine 2 as the parent machine functions as a data selection unit by executing steps S101 and S102 of FIG. 8, and functions as a verification unit by executing steps S103 to S105, and step S106. -S109 functions as management means, and the control unit 10 of the game machine 2 as a child machine functions as collation information providing means by executing steps S201-S203.

[Second form]
Next, another embodiment of the present invention will be described. In this embodiment, the procedure for checking the consistency of the quiz data Qd is changed. Therefore, the description of the first embodiment is applied as it is to the portions common to the first embodiment, and the description below will focus on the differences. As shown in FIG. 9, in the game system 1 of this embodiment, the collation unit 17 is provided in the control unit 10 of the game machine 2 as a child machine, and in the control unit 10 of the game machine 2 as the parent machine, the collation unit 17 It is omitted. In other words, in this embodiment, the child game machine 2 is in charge of collating hash values.

  FIG. 10 shows an outline of processing performed between the parent machine and the child game machine 2 in order to confirm the consistency of the quiz data Qd. First, when a question ID is selected by the question selection unit 15 of the parent device, the parent device gives the quiz data Qd corresponding to the question ID in the quiz data table 102 held by the parent device to the hash value calculation unit 16. A hash value corresponding to the quiz data Qd is calculated. The problem ID is given as selection information to all the slave units in parallel. In each slave unit, the quiz data Qd corresponding to the problem ID is specified from the quiz data table 102 held by itself, and the quiz data Qd is given to the hash value calculation unit 16 to calculate the hash value corresponding to the quiz data Qd. Is done. The hash value calculated by the master unit is sent to each slave unit. In each slave unit, the collation unit 17 collates the hash value calculated by itself with the hash value sent from the master unit. The collation result of each slave unit is sent to the master unit. In the parent device, it is determined whether or not all hash values match. If they match, the parent device is allowed to give questions to each child device, and the parent device and the child device issue questions of the quiz data Qd corresponding to the problem ID. On the other hand, if at least one determination result does not match, the consistency of the quiz data Qd between the game machines 2 is not secured, so the question ID is discarded and a new question ID is displayed in the question selection unit 15. Is selected.

  FIG. 11 shows a question control routine executed by the control unit 10 of each game machine 2 of the parent machine and the child machine in order to realize the above-described processing. These routines are executed prior to a question when a question is given in a quiz game. First, in the control unit 10 of the parent device, in steps S301 to S303, problem selection, problem ID transmission, and calculation of the hash value of the quiz data Qd corresponding to the problem ID are sequentially performed. These processes are the same as the processes in steps S101 to S103 in FIG. After the calculation of the hash value, the control unit 10 of the parent device proceeds to step S304, transmits the hash value to the child device, and then proceeds to step S305 to acquire the collation result from the child device.

  On the other hand, the control unit 10 of each slave unit obtains the problem ID transmitted from the parent unit in step S401, and calculates the hash value of the quiz data Qd corresponding to the problem ID in the subsequent step S402. Thereafter, the control unit 10 of each child device proceeds to step S403, and acquires the hash value transmitted from the parent device. In subsequent step S404, the control unit 10 of the slave unit collates the hash value calculated by itself with the hash value sent from the parent unit, and in the subsequent step S405, the collation result (whether it matches or does not match). It transmits to the game machine 2.

  When the collation results are acquired from all the slave units in step S305, the control unit 10 of the master unit proceeds to step S306 and determines whether or not all hash values match. If all the hash values match, the control unit 10 of the parent device proceeds to step S307 to notify all the child devices of permission of the question, and permits the question to the own device in the subsequent step S308, This completes the question control routine. On the other hand, if at least one hash value does not match the other hash values in step S306, the control unit 10 of the parent device proceeds to step S309 to notify each child device that the question cannot be given, and then Returning to step S301, a new problem is selected.

  When notification as to whether or not the question is permitted or not is notified as the final determination result in step S307 or step S309, the control unit 10 of the slave unit acquires the notification content in step S406 and whether or not the question permission is notified in the subsequent step S407. Determine whether or not. If it is notified that the question cannot be given, the slave unit control unit 10 discards the previously notified problem ID, returns to step S401, and waits for a notification of a new problem ID. If the question permission is notified in step S407, the slave unit control unit 10 proceeds to step S408, permits the question to the own device, and then ends the question control routine. Also by the above processing, it is possible to advance the quiz game while ensuring the consistency of the quiz data Qd between the game machines 2.

  In the above embodiment, the control unit 10 corresponds to the game control means, and the hash value calculation unit 16 as a logical device generated therein corresponds to the collation information acquisition means. Further, the game machine 2 as the parent device corresponds to the verification request device, and each of the game machines 2 as the child devices corresponds to the verification execution device. Then, the control unit 10 of the game machine 2 as the parent machine functions as a data selection unit by executing steps S301 and S302 in FIG. 11, and functions as a collation information providing unit by executing steps S303 and S304. By executing steps S305 to S309, it functions as a management unit, and the control unit 10 of the game machine 2 as a child device functions as a verification unit by executing steps S401 to S405.

  This invention is not limited to the form mentioned above, You may implement in a various form. For example, in the above embodiment, any one game machine 2 is set as a parent machine and another game machine 2 is set as a child machine. However, the parent machine does not necessarily need to be the game machine 2. For example, the quiz data table 102 may be stored in the center server 3 of FIG. 1 so that the center server 3 functions as a parent device. When another server (a server installed in the store 6 as an example) is interposed between the game machine 2 and the center server 3, that server may be used as the parent machine. When the server is a parent machine, all game machines 2 are set as child machines. In the second embodiment described above, the hash values are collated in each of all the game machines 2 set as the child machines. However, any one child machine and other parent machines and parent machines are collated. A hash value is provided from the machine, the hash value calculated by that particular child machine is checked against the hash values provided by other slave machines and the parent machine, and the check result is provided to the parent machine. The machine may determine the consistency of the game data. In other words, at least one of the parent device and the plurality of child devices may function as a collation execution device.

  In the above embodiment, each time the problem ID is selected and notified, the hash value of the quiz data is calculated. However, when the quiz data is recorded in the storage device, the hash value is calculated, and the calculated hash value is calculated. By recording in association with the problem ID, the calculation at the time of selecting the problem ID is omitted, and the hash value associated with the problem ID is replaced with the hash value associated with the same ID of another game machine 2 or the like. You may collate. The selection information is not limited to the problem ID, and may be appropriately changed as long as the game data can be uniquely specified. The matching information is not limited to the hash value as long as the value is uniquely calculated for each game data by processing the game data with a function, and can be appropriately changed.

  In the game system of the present invention, the game terminal is not limited to a game machine for business use, and can execute a game as long as the game is progressed while using game data in common among a plurality of game terminals using a network. The present invention can be applied to various game systems that use various terminal devices (for example, home game machines, personal computers, mobile phones) as game terminals. A game executed between game terminals is not limited to a quiz game. In addition to data describing quiz questions and answers, game data that should be used in common between game terminals includes various data such as characters, objects on the game, music data, and operation instruction data. The present invention can be suitably used when it is necessary to ensure consistency. In the present invention, the network to which the game terminal is connected is not limited to a wide area network such as the Internet, but may be a LAN with a limited connection range. The communication protocol is not limited to TCP / IP, and an appropriate protocol is adopted. It's okay.
