  The processing unit 33 includes one or a plurality of processors and their peripheral circuits. The processing unit 33 performs a process of progressing the game and outputting display data related to the game. Also, when an enemy appears while the game is in progress, a battle and a support battle are performed.

  FIG. 2 is a functional block diagram of the processing unit 33 of the server device 3.

  The processing unit 33 includes a control unit 331, a support battle execution determination unit 332, a battle execution unit 333, and a support battle execution unit 334. Each of these units included in the processing unit 33 is a functional module implemented by a computer program executed on a processor included in the processing unit 33. Or these each part which the process part 33 has may be mounted in the server apparatus 3 as firmware.

  After a user authentication unit (not shown) authenticates the user of the terminal 2, the control unit 331 advances the game according to a program when the terminal 2 requests the start of the game. In addition, the control unit 331 causes an enemy to appear as the game progresses. When an enemy appears, the control unit 331 creates display data related to a screen for receiving an instruction from the user, transmits the display data to the terminal 2 via the communication unit 31, and causes the screen to be displayed. An instruction is received from the user, and the instruction data is returned to the control unit 331.

  When the instruction from the user is execution of the battle, the control unit 331 checks the battle execution number counter stored in the storage unit 32, and when the value is a predetermined value (for example, once), The control unit 331 instructs the support battle execution determination unit 332 to execute the process.

  The support battle execution determination unit 332 determines whether to perform a support battle according to a predetermined probability. That is, the winning probability of the support battle is set based on the progress of the battle, and it is determined whether or not to perform the support battle by performing a lottery according to the winning probability.

The winning probability is set to be higher as the battle progress is worse. For example, the winning probability is set to be higher as the remaining amount of the enemy physical strength parameter stored in the storage unit 32 is larger. When the remaining amount of the enemy's physical strength parameter is a variable, the winning probability can be calculated by the following mathematical formula, for example.
P = (R / T) / 10 (Formula 1)
Here, P is the winning probability, R is the remaining amount of enemy health parameters, and T is the total amount of enemy health parameters. For example, when R is 90 and T is 100, P is
P = (90/100) /10=0.09
And can be calculated.

  After setting the winning probability, the support battle execution determination unit 332 performs a lottery according to the winning probability. For example, a lottery is performed by determining a numerical range corresponding to the winning probability in advance and determining whether a pseudo-random number generated using the current time or the like as a seed belongs to the numerical range. When the lottery is won, the support battle execution determination unit 332 sets the support battle execution flag stored in the storage unit 32 to ON, and then ends the process.

  The control unit 331 instructs the battle execution unit 333 to execute the process.

  The battle execution unit 333 performs a battle using card data stored in the storage unit 32 and associated with the user. For example, the enemy is damaged according to the attack power parameter of the card data. Similarly, the card data is damaged according to the enemy's attack power parameter. Card health parameters are initialized (set to the maximum value) each time a battle is executed, while enemy health parameters are not initialized, and the values after the previous battle are maintained. Shall be. When the card data and the enemy's physical strength parameter become 0, the battle execution unit 333 adds 1 to the battle execution count counter stored in the storage unit 32, and shows a battle execution status The display data is generated, and the display data is transmitted to the terminal 2 via the communication unit 31 to display the screen. Then, the process ends.

  The control unit 331 confirms the remaining amount of the enemy's physical strength parameter stored in the storage unit 32. If the remaining amount is 0, the control unit 331 determines that the enemy has been defeated, and the game progresses in a normal state ( Return to the state where no enemy appears. On the other hand, when the remaining amount is not 0 (that is, the physical strength parameter of the card data is 0), the control unit 331 determines that the enemy has lost, and the support battle execution flag stored in the storage unit 32 Confirm. When the support battle execution flag is on, the control unit 331 instructs the support battle execution unit 334 to execute the process.

  The support battle execution unit 334 reduces the enemy's physical strength parameter stored in the storage unit 32 by a predetermined amount as execution of the support battle. For example, a certain ratio to the remaining amount of enemy health parameters is reduced. Further, the amount to be reduced may be changed according to a predetermined probability. The amount to be reduced is preferably smaller than the remaining amount of the enemy's physical strength parameter in consideration of the progress of the game / battle. The support battle execution unit 334 sets the support battle execution flag to OFF, creates display data related to the screen for indicating the execution status of the support battle, and transmits the display data to the terminal 2 via the communication unit 31. After displaying the screen, the process is terminated.

As described above, by setting the winning probability of occurrence of the second event (support battle) based on the number of occurrences of the first event (battle) and the parameter value of the game target (physical strength parameter of the enemy) It is possible to make the progress of the battle advantageous to the user. Thereby, it becomes possible to prevent the user's willingness to continue the game from decreasing.
For example, even if a predetermined number of battles are performed, if the remaining amount of the enemy's physical strength parameters is large, increasing the winning probability of occurrence of the support battle makes it easier for the user to generate a support battle in a situation where the user is likely to lose, The possibility that the user can defeat the enemy can be improved. Further, when a support battle occurs, the possibility that the user can defeat the enemy can be further improved by reducing the enemy's physical strength parameter by a predetermined amount (for example, halving the remaining amount). Thereby, it becomes possible to improve a user's willingness to rejoin a battle, and it is possible to prevent a decrease in the user's willingness to continue the game.

  Note that, according to the modification, the control unit 331 may use an arbitrary number of executions as the number of executions required for determining whether or not the support battle is executed. Furthermore, once the number of times is exceeded, the presence / absence determination may be performed each time the battle is executed until the support battle is won.

  Further, the support battle execution determination unit 332 may calculate the winning probability of the support battle based on the remaining amount of the physical strength parameter in the future (after execution of the battle), not the remaining amount of the current physical strength parameter of the enemy. . This is because in the present embodiment, the support battle is performed after the execution of the battle. In addition, since the amount of damage given to the enemy by the execution of the battle is uniquely determined by parameters such as the attack power of the card data, the remaining amount of the physical strength parameter after the execution of the battle is determined before the execution of the battle It is possible.

  In addition, when the support battle is not won even if the lottery is performed a predetermined number of times, the support battle execution determination unit 332 may adjust the win probability of the support battle. Alternatively, the support battle execution unit 334 may change the amount by which the enemy's physical strength parameter is reduced.

  Moreover, the battle execution part 333 performs only a battle execution, and the terminal 2 may perform the production | generation of the display data which concern on the screen for showing the execution condition of a battle. In this case, the battle execution unit 333 may transmit data required for creating display data (for example, enemy physical strength parameters before and after the battle execution) to the terminal 2 via the communication unit 31. The same applies to the support battle execution unit 334.

  The control unit 331 may limit the number of battle executions. For example, a parameter related to the execution of the battle is provided, and the parameter is reduced by a predetermined amount every time the battle is executed, and if the remaining amount falls below the predetermined amount, the execution of the battle may be disabled.

Moreover, in the operation | movement flow shown by FIG. 3, execution of a battle (S314) and execution of a support battle (S318) were performed separately. However, when the execution of the battle is instructed, a lottery may be performed in advance, and display data combining the battle and the support battle may be generated and transmitted to the terminal 2.
For example, the processing unit 33 may perform processing according to the following operation flow.
When the instruction indicated by the instruction data received from the terminal 2 is a battle execution, the control unit 331 instructs the battle execution unit 333 to execute the process.
The battle execution unit 333 reduces the enemy physical strength parameter stored in the storage unit 32 by a predetermined amount in accordance with the card data stored in the storage unit 32.
In addition, the battle execution unit 333 adds 1 to the battle execution number counter stored in the storage unit 32.
And the battle execution part 333 complete | finishes a process.
The control unit 331 confirms the remaining amount of the enemy's physical strength parameter stored in the storage unit 32. If the remaining amount is 0, the control unit 331 receives an instruction from the screen and a user for displaying the battle execution result. Display data relating to the screen is generated, and the display data is transmitted to the terminal 2 via the communication unit 31.
On the other hand, when the remaining amount is not 0, the control unit 331 checks the battle execution number counter stored in the storage unit 32, and when the value is not a predetermined value, the control unit 331 Display data relating to the screen for indicating the execution result is created, and the display data is transmitted to the terminal 2 via the communication unit 31.
On the other hand, when the value is a predetermined value, the control unit 331 instructs the support battle execution determination unit 332 to execute the process.
The support battle execution determination unit 332 sets the winning probability of the support battle based on the progress of the battle.
In addition, the support battle execution determination unit 332 performs a lottery according to the winning probability.
