FIG. 4 is a block diagram showing a functional configuration of the player terminal 2. The player terminal 2 is an information processing device (for example, a smartphone, a mobile phone terminal, a tablet terminal, etc.) that the player can possess and use. The player terminal 2 can output the processing result of the game program transmitted from the server device 1 via the game application or the Web browser (for example, game screen display, game sound output, etc.). The player terminal 2 outputs a control unit 21 that controls the entire player terminal 2, a storage unit 22 that stores various data programs, an input unit 23 for the player to input operations, a game screen, an operation screen, and the like. It has a communication unit 25 for performing information communication with the output unit 24 and the server device 1. The control unit 21 of the present embodiment includes at least an operation information receiving unit 211, a game operation unit 212, and a processing result receiving unit 213. Further, the storage unit 22 includes at least a game operation information storage unit 221. Each functional unit of the control unit 21 can be realized by the CPU executing a program stored in the memory or the game operation information storage unit 221.

The operation information receiving unit 211 receives an operation related to the game by the player using the input unit 23. Then, the operation information receiving unit 211 outputs the received operation content to the game operation unit 212 or the server device 1.

The game operation unit 212 executes a process for operating the game application. The game operation unit 212 starts and operates the game based on the game software included in the game operation information stored in the game operation information storage unit 221 and the operation content of the player input from the input unit 23.

For example, parameters such as stamina in the game and in-game currency are managed by the server device 1. Therefore, when a process involving a change in these predetermined parameters occurs in the game, the game operation unit 212 updates the parameters managed by the server device 1 by communicating with the server device 1. Then, the game operation unit 212 receives the updated parameter from the server device 1, and continues the operation of the game based on the updated parameter.

When the server device 1 has the processing result generating unit 113, the processing result receiving unit 213 receives the processing result generated and transmitted by the processing result generating unit 113 and outputs the processing result to the player via the output unit 24. Works on.

<Example 1>
FIG. 5 is a diagram showing a configuration example of the pseudo-random number generation unit 114 in the present embodiment. The pseudo-random number generation unit 114 includes a player information acquisition unit 301, a fluctuation value acquisition unit 302, and a logical operation unit 303.

The player information acquisition unit 301 acquires player-specific player information (for example, binary or octal number, decimal number, hexadecimal number information, etc.). The player information is, for example, a player-specific player ID determined when the game application is first started, a quantified player name information, a player terminal-specific player terminal ID, and a business operator that provides the game application. It may be a value related to personal information set by the player such as an account ID of the provided platform, birthday information and payment information. The player information may be player-specific information that does not easily change until the stage is cleared. Therefore, for example, the position information of the player terminal 2 and the number of other players associated with the player (so-called number of friends, etc.) , The number of characters and items owned by the player, the number of items consumed, the total value of the character level, the value of the paid or free in-game currency currently owned, the paid or free used so far It may be game medium information regarding the game medium possessed by the player, such as the value of the in-game currency. Further, when the player information is personal information such as birthday information and payment information, for example, from the viewpoint of security, as shown in FIG. 6, a second pseudo-random number generator 304 (for example, a linear congruential method) , XORSHIFT method, etc.) may be provided before or after the player information acquisition unit 301, and before or after the logical operation unit 303.

The fluctuation value acquisition unit 302 acquires a fluctuation value (for example, binary or octal number, decimal number, hexadecimal number information, etc.) that fluctuates every predetermined cycle (for example, every minute or more) regardless of the progress of the player's game. get. The fluctuation value may be, for example, date information, day of the week information, time information not including seconds (for example, hours, minutes, etc.). Further, the fluctuation value information may be a value that changes periodically in a predetermined cycle of minutes or more by a timer or the like. The predetermined cycle may be any cycle as long as it is 1 minute cycle or more, 2 minute cycle or more, 5 minute cycle or more, 10 minute cycle or more, 15 minute cycle or more, 30 minute cycle or more, 1 hour cycle or more, It can be a one-day cycle or more.

The predetermined cycle may be a cycle based on an event in which the start timing is set for each arbitrary cycle by the administrator who manages the server device 1, and for example, an event quest in which a predetermined enemy character appears occurs. It is associated with a cycle or a campaign event where the player can get a given profit (for example, a game medium is obtained at a given time every day, less in-game currency is required for a lottery event, etc.). May be good.

The logical operation unit 303 performs a predetermined logical operation on the above-mentioned player information and the fluctuation value. For example, it may be a logical sum, a logical product, an exclusive logical sum, an exclusive logical product, or a combination thereof.

As a result, in the first embodiment, a pseudo-random number is generated from the player-specific player information and the fluctuation value information, and by using the value that fluctuates in each predetermined cycle, the player can use the luck element during the predetermined cycle. Since it is eliminated as much as possible, it is possible to formulate a strategy for clearing the stage, and it is possible to provide different stages among the players by using the player information unique to the player.

<Example 2>
FIG. 7 is a diagram showing another configuration example of the pseudo-random number generation unit 114 in the present embodiment. The second embodiment has a simpler configuration than the first embodiment. More specifically, it has a game media information acquisition unit 305 that acquires player-specific information that is unlikely to fluctuate until the stage is cleared, that is, game media information about the game medium possessed by the player described above, and obtains the game media information. As a seed, the second pseudo-random number generation unit 304 described above may be configured to generate a pseudo-random number. Further, the same may be provided by providing a player position information acquisition unit, a friend number information acquisition unit, and the like for acquiring the position information of the player terminal 2 and other player number information (so-called friend number information, etc.) associated with the player. .. As shown in FIG. 8, it may be used in combination with the player information acquisition unit 301 and the logical operation unit 303.

As a result, in the second embodiment, the same conditions may be satisfied between the players, but for the individual player, by using a fluctuation value that does not easily fluctuate until the stage is cleared, the luck factor is maximized until the stage is cleared. Since it is eliminated, it becomes possible to formulate a strategy for clearing the stage. Also, if you want to change the stage, the fluctuation value will change by executing a lottery event or playing a cleared stage, so you can easily change it when you want to change the stage content. Further, by combining with the player information, it is possible to provide different stages among the players.

<Example 3>
FIG. 9 is a diagram showing another configuration example of the pseudo-random number generation unit 114 in the present embodiment. In the third embodiment, the first embodiment is simplified as in the second embodiment. More specifically, it has a fluctuation value acquisition unit 302 that acquires a fluctuation value that fluctuates every predetermined cycle (for example, every minute or more) regardless of the game progress of the player described above, and seeds the fluctuation value. As a result, the second pseudo-random number generation unit 304 described above may be configured to generate a pseudo-random number.

As a result, in the third embodiment, the same conditions may be obtained between the players, but for the individual player, for example, by using a fluctuation value that fluctuates in a predetermined cycle of minutes or more, the fluctuation value may be used during the predetermined cycle. Since the luck factor is eliminated as much as possible until the stage is cleared, it is possible to formulate a strategy for clearing the stage.

The pseudo-random number generated by the pseudo-random number generator 114 in the present embodiment may be used not only for stage selection but also for setting other events, and a separate pseudo-random number generator may be used for other events. You may be prepared.
