JP7680758B2 - PROGRAM, CONTROL METHOD, AND INFORMATION PROCESSING APPARATUS - Google Patents

Description

The present disclosure relates to a program, a control method, and an information processing device.

In recent years, so-called social games, in which multiple players (users) can communicate with each other, have become known as games provided to mobile terminals via a communication network. In social games, for example, a user can carry out a quest using a deck (team) composed of characters selected by the user, or can play against other users or non-player characters (NPs).
Some of them involve combat with Non-Player Characters (C).

In such a battle (combat), the user can gain an advantage in the battle by constructing a deck including strong (highly capable in battle) characters. The user can obtain a strong character card as a reward, for example, by clearing a difficult quest. The user can also obtain a strong character card by winning a lottery that can be held in exchange for a fee (or without requiring a fee).

Here, when a lottery is executed in exchange for a fee, for example, there are users of the game who want to obtain a strong character even if they have to pay a large fee. On the other hand, for example, there are users who want to reduce the fee for the lottery, knowing that the probability of obtaining a strong character is low. In response to various user requests for lotteries, for example, Patent Literature 1 describes a game equipped with multiple lottery tables.

JP 2017-086556 A

However, in the lottery system disclosed in Patent Document 1, which of the multiple lottery tables is presented is determined probabilistically. For example, whether or not a game user who wants to obtain a strong character even if it means paying a lot of money can execute a lottery that allows them to obtain a strong character with a high probability depends on chance. Therefore, the lottery system disclosed in Patent Document 1 cannot be said to satisfy users' requirements for lotteries, and there is room for improvement.

In consideration of the above circumstances, an object of the present disclosure is to provide a program, a control method, and an information processing device that can meet the diverse requirements of users regarding lotteries.

[First embodiment]
(Game System Overview)
As shown in Fig. 1, the game system 10 includes a server device 11 and a plurality of terminal devices 12. For simplicity, three terminal devices 12 are illustrated in Fig. 1, but the number of terminal devices 12 may be any number.
The number of may be one or more.

The server device 11 is, for example, an information processing device managed by a game operator.
For example, mobile phones, smartphones, tablet terminals, PCs (Personal Computers),
The server device 11 and the terminal device 12 are information processing devices used by users, such as a game device or the like. The server device 11 and the terminal device 12 are communicatively connected via a network 16, such as the Internet. For example, the server device 11 and the terminal device 12 work together to execute various processes related to the game.

(Game Overview)
The game executed by the game system 10 includes various game contents. At least a part of the various game contents may be executed using game media.

Game media is electronic data used in games, such as cards, items, virtual currency, tickets, characters, avatars, level information, status information, parameter information (stamina, attack power, etc.), and ability information (skills, abilities, spells, jobs, etc.).
Any media may be acquired, owned, used, or used by the user in the game.
It is electronic data that can be managed, exchanged, synthesized, strengthened, sold, discarded, donated, etc. The manner of use of the game medium is not limited to those explicitly stated in this specification.

Hereinafter, unless otherwise specified, the term "game medium owned by a user" refers to a game medium associated with a user ID that can uniquely identify the user as an owned game medium. In addition, "granting a game medium to a user" refers to granting a game medium to a user ID as an owned game medium.
D. In addition, "selling game media owned by a user" refers to dissolving the association between the user ID and the game media owned by the user, and associating the user ID with another game medium (
For example, virtual currency or items) as the owned game media.

The game content is content that the user can play in the game, and includes, for example, quests, missions, mini-games, raising, strengthening, and synthesis of game media, game media acquisition events, virtual space exploration events, and battle events with opponents (for example, other users, enemy characters, enemy buildings, etc.). For example, when it is determined that one or more conditions (game tasks) set for each game content have been successfully achieved, the user may be given, for example, game media, etc. as a reward. The game tasks may be any task according to the content of the game content, such as a task of winning a battle against an enemy character and a task of reaching a goal point in a virtual space. In addition, the completion of a specific task (cleared task) among one or more game tasks set in the game content is also referred to as the completion of the game content. When a user playing the game content succeeds in completing the cleared task, the game content may be determined to be cleared, and the game content may end.

The various game contents may include single-play game contents and multi-play game contents. Single-play game contents are game contents (e.g., game contents for one person) that are executed based on user operations on one terminal device 12 used by one user. One terminal device 12 executes the single-play game contents alone, or one terminal device 12 and the server device 11 cooperate to execute the single-play game contents. On the other hand, multi-play game contents are game contents (e.g., game contents for multiple people) that are executed based on user operations on two or more terminal devices 12 used by two or more users, respectively, and that are common to the two or more users.
The game content common to two or more users may include, for example, game content in which at least a part of the progress process and processing results of the game content are commonly applied to the two or more users. Two or more terminal devices 12 cooperate with each other, or two or more terminal devices 12 cooperate with the server device 11 to execute the game content for multiplay.

In this embodiment, the game includes game content in which users operate game media to play against each other. Hereinafter, the game content is also referred to as battle content. Users play battle content using characters of game media (e.g., cards) owned in the game. For example, a user can advance through the battle content advantageously by owning a game medium with high rarity. In this embodiment, the game includes game content (hereinafter, simply referred to as "lottery") in which a lottery is held in which a user can acquire a game medium. A user requests the execution of a lottery in exchange for, for example, a consideration. When the lottery is executed, a winning game medium is determined based on, for example, a probability. The user can own the winning game medium. In this embodiment, the consideration for the lottery is virtual currency (in-game currency) with a currency unit of "c (coin)". The consideration for the lottery is not limited to virtual currency,
For example, it may be a ticket, an item, or the like.

The information necessary for game processing may include information 110 about the user, information 116 about the lottery, information necessary for executing the match, and the like.

The server control unit 15 transmits and receives information via the server communication unit 13. For example, the server control unit 15 may transmit at least a part of the information stored in the server storage unit 14 to the terminal device 12. In this manner, the information stored in the server storage unit 14 and the information stored in the terminal device 12 are shared and synchronized. The timing of sharing and synchronizing the information may include, for example, the timing when new information is stored in the server storage unit 14 and the timing when the information stored in the server storage unit 14 is updated, but may be determined arbitrarily.

The server control unit 15 executes game processing in cooperation with the terminal device 12. The game processing may include, for example, a process in which the user acquires cards by progressing through a game scenario, a process in which the acquired cards are exchanged, sold, synthesized, or the like, and a process in which the user fights against enemy characters.

(Configuration of terminal device)
As shown in FIG. 1, the terminal device 12 includes a terminal communication unit 17, a terminal storage unit 18, and a display unit 1.

The terminal control unit 21 includes at least one of one or more general-purpose processors that realize specific functions by reading specific programs, and one or more dedicated processors specialized for specific processes. The terminal control unit 21 controls the operation of the entire terminal device 12.

The terminal control unit 21 transmits and receives information via the terminal communication unit 17. For example, the terminal control unit 21 transmits and receives information necessary for game processing between the server device 11. For example, the terminal control unit 21 stores the information received from the server device 11 in the terminal storage unit 18.

The terminal control unit 21 starts a game application in response to a user's operation. The terminal control unit 21 executes game processing in cooperation with the server device 11. For example, the terminal control unit 21 causes the display unit 19 to display various screens. For example, a GUI (Graphical User Interface) is displayed on the screen.
The terminal control unit 21 may display a user interface (UI) on the screen. The terminal control unit 21 is capable of detecting a user operation on the screen.

(Information stored in the memory unit)
2 shows information 110 about users including at least three users. The information 110 about users is stored in, for example, the server storage unit 14 and is shared and synchronized with the terminal device 12. The information 110 about users includes various information about the users. In this embodiment, the information 110 about users includes a user ID and information 111 about cards owned by the users (see FIG. 3).
In other words, the user-related information 110 associates each of a plurality of users with information 111 of the cards owned by the users.

As mentioned above, the user ID is information that can uniquely identify a user.

The owned card information 111 includes various information about cards owned by the user in the game. When a card is acquired by the user, the acquired card is associated with the user. In this embodiment, the card is a character card. Therefore, the owned card information 111 includes information about the type and characteristics of the character associated with the card. Here, the card is not limited to a character card.

FIG. 3 is a diagram illustrating details of the information 111 of owned cards. FIG. 3 shows the information 111 of cards owned by one user. The information 111 of owned cards includes data related to a card ID, a character ID, a level, a rarity, an attribute, an attack power, a defense power, and a skill. The information 111 of owned cards is not limited to including all of these data. The information 111 of owned cards may further include other data. For example, a character associated with a card has magic points that decrease by a value according to the activation of a skill, and the maximum value of the magic points may be included in the information 111 of owned cards.

The card ID is an ID that uniquely identifies a card owned by a user. In the example of FIG.
A unique number is used as the card ID. Hereinafter, a card with a card ID of 1 will be referred to as card 1, and so on.

The character ID is an ID that uniquely identifies a game character. In this embodiment, since the card is a character card, one card ID is assigned to one character ID.
In the example of FIG. 3, unique English letters are used as the character ID. Hereinafter, a character with a character ID of A will be written as character A. Hereinafter, one character may correspond to multiple cards. In the example of FIG. 3, card 1
and card 20 are both character A's cards.

The level is information that indicates the character's growth level. For example, the higher the level value,
The character has a large degree of growth. The level value affects, for example, the attack power and defense power values. In the example of FIG. 3, the level of character C is 10. The level value increases as the user grows the character.

Rarity is information that indicates the degree of rarity of a card. For example, the higher the rarity value, the rarer the card. Rarity may be fixed. Also, the initial value of rarity is determined for each card, and may change as the user plays the game. Rarity affects, for example, the maximum values of attack power and defense power (values at the maximum level). In the example of Figure 3, rarity is represented by numbers. For example, card 1 and card 20 are both cards of character A. However, card 20, which has a rarity of 4, is rarer than card 1, which has a rarity of 2. Here,
As another example, rarity may depend on the character.

An attribute is a characteristic related to a battle or the like that a character has, and is information indicating the superiority/inferiority relationship between characters. In the example of Fig. 3, fire, water, wind, light, etc. are used as types of attributes. For example, a character with a fire attribute may be strong against attacks from a character with a wind attribute, but weak against attacks from a character with a water attribute.

Attack power and defense power are information indicating the strength of the character associated with each card, which is referenced in in-game battles and the like. Attack power, for example, affects the amount of damage inflicted on the opponent by the character's attack. The higher the attack power value, the greater the amount of damage inflicted on the opponent. Therefore, the higher the character's attack power, the more advantageous it is for clearing battle content.

Furthermore, defensive power also affects the amount of damage a character receives from an attack by an opponent, for example: the higher the defensive power value, the less damage the character receives from the opponent.
Therefore, the greater the defensive power of a character, the more advantageous it is for clearing the battle content.
Here, the numerical values of the attack power and defense power in Fig. 3 are merely examples. The attack power and defense power are independent parameters and can be set independently.

A skill is an ability possessed by a character associated with a card and used in a battle or the like. When a skill is executed (activated), a special effect different from, for example, a normal attack or defense occurs. In this embodiment, a skill is set for each card. Here, skills do not have to be set for all cards. In other words, there may be cards that do not have a skill.

In this embodiment, when a character associated with one card is selected in a battle against an enemy character, and the skill activation conditions are met, the skill associated with that character is activated. For example, when character A of card 1 is displayed on the battle screen, the "X-ray" skill is activated. The X-ray skill allows the user to see the enemy character's behavior patterns in the next battle. Also, for example, when character B of card 2 is defeated in a battle, the "absolute defense" skill is activated. The absolute defense skill allows the user to nullify damage from attacks by the enemy character in the next battle. Also, for example, when character A of card 3 is displayed on the battle screen, the "X-ray" skill is activated. The "absolute defense" skill allows the user to nullify damage from attacks by the enemy character in the next battle.
When character C wins the match, the "paralysis" skill is activated. Due to the paralysis skill, the enemy character's behavior pattern in the following matches will be the same as in the current match (the enemy character's behavior pattern does not change). Also, for example, when character A of card 20 is displayed on the match screen, the "recovery" skill is activated. Due to the recovery skill, the user's parameter value is immediately restored (for example, the user's hit point value increases by a predetermined amount).

4 is a diagram illustrating an example of the information 116 related to the lottery. As described above, in this embodiment, the game includes a lottery. By participating in the lottery, the user can own the game medium that is won. If the game medium that is won is a strong character (having high abilities in a battle), the user can advance the battle with an advantage. The information 116 related to the lottery
includes any information regarding the multiple game media that are the subject of the lottery.

The information 116 about the lottery includes a lottery number, a character ID, a rarity, an attribute,
Includes attack power, defense power, skills, and group-related data.
The lottery information 116 is not limited to including all of these data.
may include further data.
D, rarity, attribute, attack power, defense power and skill are stored in the card information 111 (
For example, the attributes, attack power, and defense power of the character D of the game medium (card) to be selected for the lottery having the lottery number 3 are Fire, 500, and 500, respectively.
500. For example, the rarity of the game medium to be selected for which the lottery number is 3 is 1, and the game medium does not have a skill.

The lottery number is an ID that uniquely identifies a card that is the subject of the lottery. In the example of FIG. 4, a number that does not overlap is used as the lottery number. The lottery number is used when determining a winning card from among a plurality of cards that are the subject of the lottery. For example, the server device 11 stores information about the lottery 1
16. Then, the server device 11 extracts one lottery number from all the lottery numbers, for example, randomly. The card having the extracted lottery number becomes the winning card. In this embodiment, information on the winning card is stored in the lottery information 1.
16. In other words, the winning card is excluded from the multiple cards to be selected. The winning card is then stored in association with the user who performed the selection.
The information of the winning card is added to the card information 111 of the user who executed the lottery after replacing the lottery number with a card ID. In this embodiment, the lottery number may be a non-sequential number in order to exclude the winning card. As another example, the lottery number may be a consecutive number indicating the order of the lottery. When the lottery is executed, the card with the smallest (or largest) lottery number among the multiple cards in the lottery information 116 is the winning card.

The group is the name of the group to which the cards to be selected belong (are divided).
In this example, the numbers 1 and 2 are used as group names.
A group with a group name of 1 is referred to as a first group. A group with a group name of 2 is referred to as a second group. In this embodiment, the multiple cards to be selected belong to the first group or the second group. Although details will be described later, the lottery process differs depending on whether the winning card belongs to the first group or the second group. In this embodiment, the information processing device (e.g., server device 11) grasps the total number of multiple cards to be selected and the number of cards belonging to each group based on the groups in the information 116 related to the lottery.

In this embodiment, among the cards to be selected, cards whose rarity is equal to or greater than a predetermined value (e.g., 4) belong to a first group. Among the cards to be selected, cards whose rarity is less than a predetermined value belong to a second group. Here, the cards belonging to the first group are strong cards that allow the user to advance the battle content advantageously, and motivate the user to perform the lottery (so-called featured cards, hereinafter also referred to as "specific cards"). In this embodiment, the number of cards belonging to the first group is less than the number of cards belonging to the second group. Here, the group to which the cards to be selected belong may be determined by an element other than rarity. For example, the group to which the cards to be selected belong may be determined according to at least one of the character ID, attribute, attack power, and defense power.

5 is a diagram illustrating an example of a lottery screen. The lottery screen is displayed on the display unit 19 of the terminal device 12 of the user who will execute the lottery. In this embodiment, the lottery is a single lottery in which multiple users who participate in the game can participate (and which can be executed). In other words, the multiple game media (cards) that are the subject of the lottery are common to the multiple users who participate in the game. The consideration (fee for executing the lottery) for the lottery may vary.

As shown in FIG. 5, the lottery screen includes a selection button 1 for allowing the user to select a lottery method.
95. When "Execute lottery immediately" is selected, the user can request the execution of the lottery by tapping the lottery execution button 198. Here, as shown in the message 197, the current consideration for one lottery is 250c. When the user taps the lottery execution button 198, the lottery is executed in exchange for 250c (by consuming 250c).

Furthermore, when "reserve a lottery" is selected, the user can reserve a lottery by inputting a reservation fee and then tapping the lottery execution button 198. The reservation fee is the fee (charge) for executing the lottery, and the user inputs the reservation fee in the reservation fee input area 196. Once the user has input the reservation fee, it becomes possible to tap the lottery execution button 198. The reservation of the lottery is completed when the user taps the lottery execution button 198. If the fee for the lottery changes after the lottery is reserved, and the fee matches the reservation fee, the information processing device (e.g., server device 11) determines that the user has requested the execution of the lottery.
In other words, when a lottery is reserved, if the consideration matches the reservation consideration, the lottery is held. Here, the match between the consideration and the reservation consideration may include not only a strict match, but also a case where the consideration and the reservation consideration are close to each other. Since the consideration may change suddenly, the information processing device may determine that there is a match, for example, when the consideration that was below the reservation consideration becomes equal to or greater than the reservation consideration, or when the consideration that was above the reservation consideration becomes equal to or less than the reservation consideration.

For example, in the case of a lottery in which the price increases as the probability of obtaining a strong character card increases, a user who wants to obtain such a character card can reserve the lottery by inputting a reservation price higher than the current price. Also, since it is acceptable for the probability of obtaining a strong character card to decrease, a user who wants to reduce the price of the lottery can reserve the lottery by inputting a reservation price lower than the current price. Also, a user who thinks that the current price of the lottery is appropriate can immediately enter the lottery without making a reservation.

(Changes in Consideration)
In this embodiment, when a user requests a lottery to be held (or when the consideration matches the reservation consideration), the information processing device (e.g., server device 11) determines the winning card using the lottery number as described above, and stores it in association with the user who held the lottery. The information processing device also adjusts the multiple cards that are the subject of the lottery as described below, and varies the consideration for the next lottery to be held. Here, the consideration for the lottery does not necessarily vary. In the following, varying the consideration includes maintaining the consideration.

FIG. 6 is a conceptual diagram for explaining the lottery process (adjustment of a plurality of cards to be selected) executed by the information processing device in this embodiment. The circles shown in FIG. 6 represent a plurality of cards 50 to be selected. Each circle of the plurality of cards 50 represents one card.
belongs to the first group 51 or the second group 52. When a user requests execution of a lottery (or when the consideration matches the reservation consideration), the information processing device (e.g., the server device 11) determines the winning card 50a. Here, in the example of Fig. 6, the winning card 50a is one, but it may be multiple.

In the information processing device of this embodiment, when the winning card 50a belongs to the first group 51, no other card is added to the first group 51. In this case, as shown in FIG. 6, the number of cards belonging to the first group 51 is reduced from X (e.g., 300) to X-1 (e.g., 29
9). Furthermore, the number of cards belonging to the second group 52 remains unchanged at Y (e.g., 9700). The cards belonging to the first group 51 are specific cards that motivate the user to enter a lottery. In the next lottery to be executed, the information processing device varies (reduces) the consideration since the number of specific cards has decreased. When a card belonging to the first group 51 is selected, the information processing device in this embodiment reduces the consideration for the next lottery to be executed by 1c from the current consideration. As another example, the information processing device in this embodiment may determine the consideration by a calculation using the total number of multiple cards 50 to be selected for the lottery ((X-1)+Y) or the number of cards belonging to the first group 51 (X-1). For example, the initial value of the consideration for the lottery is set to P0, and the consideration for the next lottery to be executed is calculated by multiplying P0 by ((X-1)+Y)/(X
+Y), or (X-1)/X.

7 is a conceptual diagram for explaining another lottery process (adjustment of a plurality of cards to be selected) executed by the information processing device in this embodiment, which is a continuation of FIG. 6. When the winning card 50a belongs to the second group 52, the information processing device in this embodiment adjusts the number of cards belonging to the second group 52, which is the same as the winning card 50a, to the plurality of cards 50.
At this time, as shown in FIG. 7, the number of cards belonging to the second group 52 is Y(
For example, 9700. The number of cards in the first group 51 is X-1
(e.g., 299) remains unchanged.
If a card belonging to group 2 is selected, the prize for the next lottery drawing will remain the same as the current prize.

Here, the process of adding cards belonging to the same group as the winning card 50a to the multiple cards 50 is performed by the information processing device (e.g., the server device 11) updating the information 116 related to the lottery. For example, in FIG. 4, when the card of character E with lottery number 4 is the winning card 50a, the information processing device removes the card from the information 116 related to the lottery. Then, the information processing device adds information of another card belonging to the second group with a new lottery number to the information 116. The information processing device may, for example, access a database including information of all cards used in the game, and select the card to be added (another card belonging to the second group).

8 shows the time change of values related to the lottery executed by the information processing device in this embodiment. Here, the value related to the lottery is specifically the consideration or the number of multiple cards 50. In this embodiment, the consideration changes (decreases) in conjunction with the number of multiple cards 50. The information processing device shows the changed consideration to the user and determines whether the changed consideration matches the reserved consideration input by the user (see FIG. 5).

Here, as shown in Fig. 8, when the value related to the lottery reaches a threshold value, the information processing device changes the value related to the lottery to an initial value (or another value). First, a case where the value related to the lottery is the consideration for the next lottery to be executed will be described. In the lottery executed by the information processing device in this embodiment, replenishment is performed when the winning card 50a belongs to the second group 52.
However, if the winning card 50a belongs to the first group 51, the winning card 50a is not replenished. Therefore, as the user of the game performs the lottery (as time passes), the first group 51 is
The number of cards (specific cards) belonging to group 51 of the lottery draw will decrease. The information processing device performs processing to lower the price because the expected value of winning the specific cards will decrease. Here, if the number of specific cards decreases to an extent that winning is almost impossible (for example, 10 cards), it is possible that there will be almost no users who run the lottery draw (there will be almost no demand for the lottery draw). Therefore, the information processing device
The threshold value is set to a consideration (second value) that corresponds to when the number of specific cards has decreased to such an extent that a win is hardly expected. Then, when the consideration reaches the threshold value (times t1 and t2 in the example of FIG. 8), the information processing device changes the consideration to an initial value (or another value). Here, the other value is a value different from the initial value (the value at time t0 in the example of FIG. 8, e.g., 300c). The other value may be, for example, a value that encourages the user to participate in the lottery (e.g., 200c). In this embodiment, the consideration and the number of multiple cards 50 that are the subject of the lottery are linked. Therefore, when the consideration reaches the threshold value, the information processing device also changes the number of multiple cards 50 that are the subject of the lottery to the initial value (or another value).
In this embodiment, the information processing device changes the number of cards 5 to be selected.
By changing (replacing) 0, the number is changed to the initial value (or another value). By changing the multiple cards 50, new cards become available, so that users who have already performed the lottery can be expected to perform the lottery again.

Next, a case where the value related to the lottery is the number of the plurality of cards 50 will be described. As described above, as the user of the game executes lotteries (as time passes), the number of cards (specific cards) belonging to the first group 51 decreases. The information processing device calculates the number of the plurality of cards 50 (third value) corresponding to the time when the number of specific cards has decreased to such an extent that a win is hardly expected.
is set as the threshold value. Then, when the number of the multiple cards 50 reaches the threshold value (times t1 and t2 in the example of FIG. 8 ), the information processing device changes the number of the multiple cards 50 to the initial value (or another value). Here, the other value is the initial value (the value at time t0 in the example of FIG. 8 , for example, 100
The value is different from the value of the card 50 (e.g., 8000). The other value may be a value that encourages the user to participate in the lottery (e.g., 8000). In this embodiment, the value is a combination of the amount and the multiple cards 50 to be selected.
Therefore, when the number of the multiple cards 50 reaches a threshold value, the information processing device
As described above, in the present embodiment, the information processing device changes (replaces) the multiple cards 50 that are the subject of the lottery, thereby changing the number of the cards 50 to the initial value (or to another value).

(flowchart)
FIG. 9 is a flowchart showing a control method for the lottery executed by the server device 11 in this embodiment.

First, the server device 11 stores a plurality of game media (e.g., a plurality of cards 50) belonging to the first group 51 or the second group 52 (step S1). In this embodiment, the server device 11 updates, for example, the information 116 related to the lottery, and stores the information 116 in the server storage unit 14.
The information 116 relating to the lottery may be shared and synchronized with the terminal device 12.

The server device 11 waits until the user requests the lottery to be held in exchange for the payment (No in step S2). If the user requests the lottery to be held in exchange for the payment (Yes in step S2), the server device 11 proceeds to the process of step S3. The server device 11 determines that the lottery has been requested by the user even if the payment matches the reservation payment.

The server device 11 excludes the selected game medium (e.g., the selected card 50a) from the plurality of game media (e.g., the plurality of cards 50) (step S3).
For example, by removing the information on the winning card 50a from the lottery information 116,
The process of step S3 is carried out.

The server device 11 stores the selected game medium in association with the user (step S4
The server device 11 performs the process of step S4 by, for example, adding the information on the winning card 50a to the information 111 on the cards owned by the user who performed the lottery.

If the game medium selected by lottery belongs to the first group 51 (Yes in step S5), the server device 11 varies the prize for the next lottery (step S6).

If the game medium selected by the lottery does not belong to the first group 51, that is, if the game medium selected by the lottery belongs to the second group 52 (No in step S5), the server device 11
The server device 11 adds the game media belonging to the second group 52, the number of which is equal to the number of the game media selected by lottery, to the plurality of game media (e.g., the plurality of cards 50) (step S7).
The number of game media belonging to the second group 52 is prevented from decreasing.

If the lottery has not ended (No in step S8), the server device 11 returns to the process of step S1. In the process of step S1, the server device 11 updates the information 116 related to the lottery to reflect the game medium selected by the lottery.

If the lottery has ended (Yes in step S8), the server device 11 ends the series of lottery-related processes.

As described above, the information processing device (e.g., server device 11) according to the present embodiment executes a game process including a lottery to determine a winning game medium (e.g., a winning card 50a). The information processing device includes a storage unit (e.g., server storage unit 14) that stores a plurality of game media (e.g., a plurality of cards 50) belonging to the first group 51 or the second group 52, and a control unit (e.g., server control unit 15). When a user requests execution of a lottery in exchange for a consideration, the control unit determines a winning game medium from among the plurality of game media, with the plurality of game media being the objects of the lottery. In addition, the control unit excludes the winning game medium from the plurality of game media. In addition, the control unit associates the winning game medium with the user and stores it in the storage unit. When the winning game medium belongs to the first group, the control unit varies the consideration for the next lottery to be executed. When the winning game medium belongs to the second group, the control unit adds the same number of game media belonging to the second group as the winning game medium to the plurality of game media.

The lottery by the information processing device according to the present embodiment is a single lottery, and the consideration fluctuates over time, for example, as shown in FIG. 8. When the consideration is high, the number of specific cards is large, so the probability of obtaining a specific card is high. Therefore, for example, a user of a game who wants to obtain a strong character even if it costs a lot can execute a lottery at a timing when the consideration is high (immediately after times t0, t1, and t2 in the example of FIG. 8). Also, for example, a user who wants to reduce the consideration for the lottery while recognizing that the probability of obtaining a strong character is low can execute a lottery at a timing when the consideration is low (immediately before times t1 and t2 in the example of FIG. 8). Therefore, the information processing device according to the present embodiment can respond to various requests from users regarding lotteries.

Here, the first lottery requires a lot of money but has a high probability of obtaining a strong character,
It is possible to meet the needs of different users by preparing a second lottery with a low reward but a high probability of obtaining a strong character. However, the existence of two lotteries with exactly the same items in the game complicates the game system and may confuse users.

The lottery by the information processing device according to this embodiment is one of the lotteries configured as above.
The information processing device according to the present embodiment does not complicate the game system. Furthermore, compared to the case where the first lottery and the second lottery are prepared, the information processing device according to the present embodiment:
It is possible to keep the load of the lottery process, the amount of data, and the amount of communication low.

[Second embodiment]
The information processing apparatus according to the second embodiment will be described with reference to FIGS.
In this embodiment, it is possible to set a limit value (specifically, an upper limit value) for the prize for the lottery by the process described below. The game system 10 (see FIG. 1) of the information processing device according to this embodiment, the information stored in the storage unit (see FIGS. 2 to 4), and the lottery screen (see FIG. 5)
Since the steps (see reference number 100) and (b) are the same as those in the first embodiment, the description thereof will be omitted.

10 is a conceptual diagram for explaining the lottery process (adjustment of a plurality of cards to be selected) executed by the information processing device in this embodiment. The elements shown in FIG. 10 are the same as those in FIG. 6, for example, and therefore will not be described.

In the present embodiment, when the winning card 50a belongs to the first group 51 and a first condition described later is satisfied, the information processing device outputs the same number of first cards as the winning card 50a.
10, the game contents belonging to the first group 51 are added to the plurality of cards 50. At this time, as shown in FIG. 10, the number of cards belonging to the first group 51 remains unchanged at X (e.g., 300).
Furthermore, the number of cards belonging to the second group 52 remains unchanged at Y (e.g., 9700). When a card belonging to the first group 51 wins, the information processing device in this embodiment maintains the current prize for the next lottery.

FIG. 11 is, for example, a continuation of FIG. 10, and is a conceptual diagram for explaining another lottery process (adjustment of multiple cards to be selected) executed by the information processing device in this embodiment. When the winning card 50a belongs to the second group 52 and the first condition described below is satisfied, the information processing device in this embodiment does not add another card to the second group 52. At this time, as shown in FIG. 11, the number of cards belonging to the second group 52 changes from Y (e.g., 9700) to Y-1 (e.g., 9699). Also, the number of cards belonging to the first group 51 remains unchanged at X (e.g., 300). The cards belonging to the first group 51 are,
This is a specific card that motivates the user to enter a lottery. In the next lottery, the number of cards other than the specific card has decreased, thereby improving the probability of winning the specific card, and so the information processing device varies (increases) the consideration. When a card belonging to the second group 52 is won, the information processing device in this embodiment increases the consideration for the next lottery from the current consideration by 1c. As another example, the information processing device in this embodiment may determine the consideration by performing a calculation using the total number of cards 50 to be drawn (X+(Y-1)), or the number of cards belonging to the second group 52 (Y-1). For example, the initial value of the consideration for the lottery is set to P0, and the consideration for the next lottery is calculated by multiplying P0 by (X+Y)/(X+(
It may be determined by multiplying by Y/(Y−1), or Y/(Y−1).

12 is a conceptual diagram for explaining the process (adjustment of the plurality of cards to be selected) executed by the information processing device in this embodiment when the first condition is not satisfied. The first condition is that the number of the plurality of cards 50 is greater than a first value. The first value is selected as the number of the plurality of cards 50 such that the winning probability of a specific card is within an appropriate range. The first value is
For example, it may be the total number of the plurality of cards 50 when the number of cards belonging to the second group 52 is half of the initial value. Here, in this embodiment, the number of cards belonging to the first group 51 does not change to X. Therefore, the first condition can be rephrased as the number of cards belonging to the second group 52 being greater than a certain value.

In the example of Fig. 12, the first value is represented by X+Yc. When the card belonging to the second group 52 becomes Yc, which is a value smaller than Y (when the first condition is not satisfied), the information processing device adds to the plurality of cards 50 the same number of cards that belong to the same group as the selected card 50a as the selected card 50a. This maintains the total number of the plurality of cards 50, the number of cards that belong to the first group 51, and the number of cards that belong to the second group 52. The information processing device also maintains the value of the card.

13 shows the change over time of the consideration executed by the information processing device in this embodiment. In this embodiment, the consideration changes (increases) as the number of the multiple cards 50 decreases.

13, when the first condition is no longer satisfied at time t3, the information processing device maintains the consideration at the upper limit value, thereby keeping the probability of winning a specific card in the lottery within an appropriate range.

(flowchart)
FIG. 14 is a flowchart showing a control method for the lottery executed by the server device 11 in this embodiment.

First, the server device 11 stores a plurality of game media (e.g., a plurality of cards 50) belonging to the first group 51 or the second group 52 (step S11).

The server device 11 waits until the user requests the lottery to be held in exchange for the payment (No in step S12). If the user requests the lottery to be held in exchange for the payment (Yes in step S12), the server device 11 proceeds to the process of step S13. The server device 11 determines that the lottery has been requested by the user even if the payment matches the reservation payment.

The server device 11 excludes the selected game medium (e.g., the selected card 50a) from the multiple game media (e.g., the multiple cards 50) (step S13).

The server device 11 stores the selected game medium in association with the user (step S1
4).

If the first condition is satisfied (Yes in step S15), the server device 11 proceeds to the process of step S17.

If the first condition is not satisfied (No in step S15), the server device 11 adds to the multiple game media the same number of game media as the selected game medium and which belong to the same group as the selected game medium (step S16).

When the selected game media belong to the first group 51 (Yes in step S17), the server device 11 adds the same number of game media belonging to the first group 51 as the selected game media to the multiple game media (e.g., multiple cards 50) (step S18). In other words, the server device 11 prevents the number of game media belonging to the first group 51 from decreasing.

If the selected game medium does not belong to the first group 51, that is, if the selected game medium belongs to the second group 52 (No in step S17), the server device 11
As described above, the prize for the next lottery is changed (step S19).

If the lottery has not ended (No in step S20), the server device 11
Return to processing.

If the lottery has ended (Yes in step S20), the server device 11 ends the series of lottery-related processes.

As described above, the information processing device (e.g., server device 11) according to this embodiment executes game processing including a lottery to determine a winning game medium (e.g., a winning card 50a). The information processing device includes a memory unit (e.g., server memory unit 14) that stores multiple game media (e.g., multiple cards 50) belonging to the first group 51 or the second group 52, and a control unit (e.g., server control unit 15). When a user requests the execution of a lottery in exchange for a consideration, the control unit determines a winning game medium from among the multiple game media, with the multiple game media as the objects of the lottery. The control unit also excludes the winning game medium from the multiple game media. The control unit also associates the winning game medium with the user and stores it in the memory unit. The control unit also stores the winning game medium in a manner that the winning game medium belongs to the first group and is a card that belongs to the first group.
When the first condition is satisfied, the control unit adds to the plurality of game media the same number of game media belonging to the first group as the game media selected by the lottery. When the game medium selected by the lottery belongs to the second group and the first condition is satisfied, the control unit varies the consideration for the next lottery to be executed.

The information processing device according to this embodiment has the same effect as that of the first embodiment. In addition, by saturating the compensation at the upper limit, the information processing device according to this embodiment can keep the probability of winning a specific game medium within an appropriate range.

Although the present disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these modifications and corrections are included in the scope of the present disclosure. For example, the functions included in each means, each step, etc. can be rearranged so as not to be logically inconsistent, and multiple means or steps can be combined or divided into one.

(Modifications, etc.)
In the above embodiment, the cards belonging to the first group 51 were specific cards that motivated the user to take part in the lottery. The cards belonging to the second group 52 were not specific cards. Here, the first group 51 and the second group 52
For example, as a modification of the first embodiment,
When the cards belonging to the first group 52 are designated as specific cards, the probability of winning the specific card increases over time. In this case, the prize may be increased as the probability of winning the specific card increases.
In the case where a card belonging to category 2 is set as a specific card, the probability of winning the specific card decreases over time. In this case, the price may be reduced as the probability of winning the specific card decreases.

In the above embodiment, when reserving a lottery, the user inputs a reservation fee (see FIG. 5). Here, when reserving a lottery, it may be possible to input conditions other than the reservation fee. For example, instead of inputting the reservation fee, the user may input a lottery budget (e.g., 1000c) and the number of lotteries (e.g., 8 times). When the fee becomes equal to or less than the value obtained by dividing the lottery budget by the number of lotteries (e.g., 125c), the information processing device determines that the user has requested the execution of a lottery. Then, the information processing device automatically executes the lottery continuously for the number of lotteries input by the user. Furthermore, when reserving a lottery, the user may input a reservation deadline (e.g.,
By allowing the input of conditions other than the reservation price, the user can carry out a lottery based on desired conditions, for example, without having to constantly check the price fluctuations in the game.

In the above embodiment, the information processing device executes a process of excluding a winning game medium (e.g., the winning card 50a) from the multiple game media (e.g., the multiple cards 50). Here, if the winning card 50a is not a specific card, the information processing device does not need to execute the excluding process. In other words, if the winning card 50a is a specific card, a process of excluding information on the winning card 50a from the lottery-related information 116 may be executed.

In the above embodiment, the server device 11 varies the consideration for the lottery. In addition, data communication between the server device 11 and the terminal device 12 of the user who executes the lottery takes a certain amount of time. Therefore, there is a possibility that the consideration for the lottery (message 197) displayed on the display unit 19 of the terminal device 12 differs from the consideration managed by the server device 11. In such a case, the server device 11 may execute the lottery with the consideration for the lottery displayed on the terminal device 12 of the user (the consideration recognized by the user). For example, when the user taps the lottery execution button 198, the consideration for the lottery displayed on the display unit 19 is transmitted to the server device 11 together with a request to execute the lottery from the user. Then, the server device 11 executes the lottery for the user using the received consideration for the lottery. With such a configuration, it is possible to avoid a disadvantage to the user due to a delay in data communication, etc.

Furthermore, in the above embodiment, a part of the game screen may be a web display that is displayed on the display unit 19 of the terminal device 12 based on data generated by the server device 11, and a part of the game screen may be a native display that is displayed by a native application installed on the terminal device 12. In this way, the game in the above embodiment may be a hybrid game in which the terminal device 12 and the server device 11 each handle part of the processing.

Furthermore, the server device 11 and the terminal device 12 may cooperate to execute various processes related to the game. For example, the server device 11 and the terminal device 12 may share the execution of a series of processes. Also, for example, the server device 11 and the terminal device 12 may each execute the same process. If the processing results of the same process match between the server device 11 and the terminal device 12, the server device 11 and the terminal device 12 may complete the process. If the processing results do not match between the server device 11 and the terminal device 12, the server device 11
The terminal device 12 may complete the process by determining that the processing result of the other device (for example, the server device 11) is correct. As another example, when the processing results do not match between the server device 11 and the terminal device 12, the server device 11 and the terminal device 12 may rewind the process before the execution of the same process. With this configuration, even if the communication quality between the server device 11 and the terminal device 12 temporarily deteriorates, the likelihood of the process being immediately interrupted decreases. Also, even if an unauthorized process such as rewriting a parameter is performed in the terminal device 12, the likelihood of the unauthorized process being eliminated increases.

In addition, for example, a computer, a mobile phone, or the like can be suitably used to function as the terminal device 12 or the server device 11. The terminal device 12 or the server device 11 stores a program describing the processing contents for realizing each of the above functions in an accessible storage unit,
This can be realized by having the CPU read and execute the program.
