Abstract

PROBLEM TO BE SOLVED: To provide a game that secures fairness of a lottery while suppressing a worst consumption risk in a computer game having the lottery as game constituents.SOLUTION: A basic lottery to which winning probability is assigned to every character to be used for a game is performed for obtaining characters with consumption of game points as a condition. An upper limit number of executions changes as designation by a player or a player's attribute changes. When the execution number reaches the upper limit number, the player is provided with a prescribed character. The higher the upper limit number is set, the more advantageous character for the player is provided. Other than the arrival at the upper limit number of execution number, a variety of conditions for providing characters may be defined.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a computer game, and more particularly to a lottery control method for giving a privilege to a player.

  There is a game in which a player collects various characters and battles the opponent team with each other. Character abilities vary, and there are characters that are easy to obtain and characters that are difficult to obtain (hereinafter referred to as “rare characters”).

  A typical method for acquiring a character is a lottery (restoration extraction method) that can be executed by consuming game points (included in game elements). In this lottery (restoration extraction method), each lottery probability is the same. Since the winning probability of a rare character is set low, even if a large amount of game points are consumed, a desired rare character is not always available. For example, even a rare character with a winning probability of 1% (1/100) is not always available if the lottery is executed 100 times. In the lottery, there is a risk (hereinafter referred to as “worst consumption risk”) that the amount of game points consumed to obtain rare characters becomes larger than expected.

  Patent Document 1 proposes a method for increasing the winning probability of a character instead of decreasing the attribute value (level) of the character. Patent Document 2 proposes a method of drawing a character group (population) by non-restoration extraction instead of restoration extraction.

Japanese Patent No. 5829346 JP 2013-247777 A

  The lottery method of Patent Document 1 can increase the possibility of obtaining a rare character, but does not fundamentally eliminate the worst consumption risk.

  If it is the lottery method (non-restoration extraction type) of patent document 2, the worst consumption risk can be avoided. However, another problem arises that it is difficult to set the winning probability of the rare character low. For example, in the case of a lottery box containing 50 characters (one rare character), the theoretical maximum number of lottery executions (hereinafter referred to as “worst number of times”) for obtaining a rare character is 50 times. However, the winning probability of the rare character cannot be set to 2% (1/50) or less. On the other hand, if the lottery box contains 5000 characters, the winning probability of the rare character can be lowered to 0.02% (1/5000), but the worst number is 5000 times.

  The present invention has been completed based on the above-mentioned problem recognition, and its main object is to provide a mechanism for ensuring the fairness of the lottery while suppressing the worst consumption risk.

An information processing apparatus according to the present invention includes a game execution unit that controls the progress of a game based on a game medium held by a player, and a lottery in which a winning probability is assigned to each game medium, and consumes game elements. A basic lottery execution unit for executing a basic lottery as a condition; and a setting unit for changing a consumption amount of game elements necessary for satisfying a predetermined condition depending on the player.
The basic lottery execution unit provides a privilege that is more advantageous to the player as the consumption amount increases when a predetermined condition is satisfied.

  According to the present invention, it becomes easy to maintain the fairness of the lottery while suppressing the worst consumption risk.

  After briefly explaining the outline of the computer game shown in the present embodiment, a specific configuration and control method of the game system 100 will be described.

  The player has a plurality of characters (game media). Then, play against the characters of the opponent team. The opponent may be a computer or another player connected via a communication network. If you win the match, you can earn game points (game elements). Characters have strengths, but level up as you play. The character that has reached the maximum level further evolves into a stronger character by being combined with another character (hereinafter referred to as “material character”). The player attempts to level up the character again. The character is strengthened by repeating level up and evolution.

  Characters can be obtained in battles, or can be obtained by lottery (hereinafter referred to as “basic lottery” to distinguish them from other lotteries). Every time a basic lottery is executed, game points are consumed. In the basic lottery in the present embodiment, one or a plurality of characters are restored and extracted at random from a lottery target including a large number of characters. In the basic lottery in the present embodiment, one or more characters are restored and extracted based on the lottery probability set for the character.

In the basic lottery, an upper limit number (threshold) is set. When the number of executions of the basic lottery, more precisely, the count value that changes according to the number of executions reaches the upper limit number (hereinafter referred to as “satisfaction condition established”), a predetermined character (hereinafter “ceiling character”) Is provided unconditionally. As the ceiling character, a character having a certain degree of rarity is assumed. While expecting a rare character to be obtained by the basic lottery, the player can reliably acquire the ceiling character when the count value reaches the upper limit number of times.
By such a control method, the worst consumption risk for the ceiling character is suppressed.

[First Embodiment]
FIG. 1 is a hardware configuration diagram of the game system 100.
In the game system 100, a game server 102 and a plurality of game terminals 104 a, 104 b, 104 c... 104 n (hereinafter collectively referred to as “game terminal 104” when collectively referred to or not particularly distinguished) via the Internet 106.

The data processing unit 107 performs various processes based on the data acquired by the communication unit 110 and the data stored in the data storage unit 108. The data processing unit 107 also functions as an interface between the communication unit 110 and the data storage unit 108.

  The data storage unit 108 includes a game program storage unit 142, a player information storage unit 130, a character information storage unit 132, a lottery setting storage unit 134, and a count setting storage unit 136. The game program storage unit 142 stores a game program. The player information storage unit 130 manages player information (described later with reference to FIG. 3). The character information storage unit 132 manages character information (described later with reference to FIG. 4). The lottery setting storage unit 134 manages basic lottery setting information (described later in connection with FIG. 5). The count setting storage unit 136 manages information related to the count setting of the number of lotteries (described later with reference to FIG. 8).

The data processing unit 107 includes a game execution unit 112 and a lottery execution unit 114. The game execution unit 112 controls the basic progress of the game. The game execution unit 112 performs a win / loss determination when playing against an enemy character according to the attribute value (ability) of the character held by the player. The game execution unit 112 determines the superiority or inferiority based on the difference or combination of the attribute value of the character presented by the player and the attribute value of the enemy character, and determines the victory or defeat of the character while taking into account the randomness based on the superiority or inferiority To do. Such a win / loss determination method can be realized by applying existing technology.
The lottery execution unit 114 executes various lotteries including the basic lottery.

  The lottery execution unit 114 includes a basic lottery execution unit 118, a settlement setting unit 116, and a lottery counting unit 140. The basic lottery execution unit 118 executes basic lottery. In the basic lottery, a character to be provided to the player is randomly selected from a lottery target (population) including a plurality of characters.

The basic lottery execution unit 118 selects a ceiling character to be provided to the player when the number of executions of the basic lottery reaches the upper limit number. The settlement setting unit 116 sets the upper limit number (upper limit value). The lottery counting unit 140 counts the number of executions of the basic lottery and updates a count value (described later) corresponding to the number of executions. The lottery counting unit 140 includes a replacement unit 144 that manages the exchange rate of count values.
Details of the lottery execution unit 114 will be described later.

  The game terminal 104 includes a U / I (user interface) unit 122, a communication unit 124, a data processing unit 126, and a data storage unit 128. In addition to accepting operations from the player, the U / I unit 122 is responsible for processing related to the user interface, such as image display and audio output. The communication unit 124 is in charge of communication processing with the game server 102 and other game terminals 104 via the Internet 106. The data storage unit 128 stores various data. The data processing unit 126 executes various processes based on the data acquired by the U / I unit 122 and the communication unit 124 and the data stored in the data storage unit 128. The data processing unit 126 also functions as an interface for the U / I unit 122, the communication unit 124, and the data storage unit 128.

  The communication unit 124 acquires various game information from the game server 102, and the data processing unit 126 displays a game screen on the U / I unit 122. Further, the U / I unit 122 detects various inputs by the player, and the data processing unit 126 notifies the game server 102 of input information via the communication unit 124. In accordance with this input information, the data processing unit 107, in particular, the game execution unit 112 controls the progress of the game.

FIG. 3 is a data structure diagram of the player information storage unit 130.
The player is identified by the player ID. The player information storage unit 130 manages the attributes of each player (hereinafter referred to as “player attributes”) and the progress of the game. In the computer game in the present embodiment, a plurality of types of basic lotteries are provided. For example, a player whose player ID is P001 (hereinafter referred to as “player (P001)”) is 40 years old and has 12,000 game points. The player (P001) is executing three basic lotteries of basic lotteries 1-3. The player (P002) is 17 years old and holds 4,500 game points. The player (P002) also executes the three basic lotteries 1 to 3.

  In the first embodiment, the number of executions of the basic lottery and the count value have the same meaning. In the second embodiment, the number of executions does not necessarily match the count value, but this will be described in detail later.

About Player (P001) The upper limit number of times of the basic lottery 1 is set to 40 times, and the number of times of execution (count value) is 25 times. That is, the player (P001) can acquire the ceiling character by performing the basic drawing 1 15 times. On the other hand, the upper limit of the basic lottery 3 is set to 80 times, and the count value is 6 times. The player (P001) cannot acquire the ceiling character unless the basic lottery 3 is executed 65 more times.
When the count value of the basic lottery reaches the upper limit number, the count value is reset to zero. The upper limit number is a basic lottery break (milestone), and does not mean that the basic lottery can be executed only until the upper limit number is reached. Unless the limit number mentioned later is set, there is no limit to the number of times the basic lottery is executed.

On the other hand, for the player (P002), the upper limit of the basic lottery 1 is set to 30, which is different from the setting of the player (P001). Similarly, for the player (P002), the upper limit number of the basic lottery 2 is set to 50, which is also different from the setting of the player (P001).
In the present embodiment, the upper limit number varies depending on the player. A method of setting the upper limit number according to the player will be described later.

FIG. 3 shows player attributes and possession states. As an example of player attributes, age is exemplified, but in addition to this, for a predetermined period, for example, last month's consumption of game points, rank indicating the player's game proficiency, play time, number of login days, gender, residence, resources, Various information such as occupations may be registered.
As an example of the possession state, the possessed game points are exemplified, but various information such as the number and types of the possessed characters and items may be registered.

FIG. 4 is a data structure diagram of the character information storage unit 132.
The character is identified by a character ID. The character information storage unit 132 manages the attributes of each character. The character is given a rare rank. The rare rank is obtained by indexing in advance the difficulty of acquiring the character and the height (character strength) of the parameter (attribute value) set for the character. The higher the rare rank, the harder it is to get and generally a stronger character.
A character with a high rare rank is a “rare character”.

  The character (C0001) has a rare rank of 1, and the winning probability in the basic lottery is set to a relatively high probability of 10%. The initial setting value of the hit point (physical strength) of the character (C0001) is 10. The character is leveled up by repeating battles and synthesizing the material character, and the attribute value of the character changes favorably to the player as the level increases. For example, the hit point becomes higher as the character (C0001) is leveled up.

The maximum level (master level) of the character (C0001) is 50. When the character (C0001) reaches the maximum level, the maximum hit point is 30. The character (C0001) can only be leveled up to level 50. For example, if the same type of character (C0001) or a predetermined character (item) is synthesized as a material, the character (C0001) becomes a stronger character (C0005). ).
Even weak characters can be upgraded to a stronger character by leveling them up to the maximum level and combining them with material characters (material items) necessary for evolution.

  The character (C0005) has a rare rank of 2, and the winning probability in the basic lottery is set to 8%. That is, the character (C0005) is a character that has a higher rare rank and a lower winning probability (high rarity) than the character (C0001) before evolution. The initial value of the hit point of the character (C0005) is 50. The character (C0005) is an evolution of the character (C0001), has a high rarity (rare rank), and the attribute value (hit point) also changes favorably for the player.

The character (C0005) can evolve in two types. When the character (C0003) is synthesized as a material character, the character (C0005) evolves to a character (C0011). On the other hand, when the character (C0012) is synthesized as a material character, the character (C0005) evolves to a character (C0024).
Both the character (C0011) and the character (C0024) are more powerful characters than the character (C0005).

  No material character is registered in the character (C0004). For this reason, even if the character (C0004) reaches the maximum level, it cannot be further evolved.

In FIG. 3, the winning probability is shown as a unique value, but may be set as a wide value such as 7 to 12%. For example, the winning probability of the character (C0001) in the basic lottery 1 may be set to 8%, and in another basic lottery 2, the winning probability may be set to 12%. The winning probability may be changed according to other parameters such as the upper limit number of times.
In FIG. 4, hit points are illustrated as character attributes, but various other attributes may be set within a common sense range such as attack power, defense power, agility, and magic power.

FIG. 5 is a data structure diagram of the lottery setting storage unit 134.
The basic lottery is identified by a lottery ID. The lottery setting storage unit 134 manages setting conditions for each basic lottery. For the basic lottery (L01), four types of upper limit counts of 50, 80, 100, and 150 can be set as the upper limit count. In the basic lottery (L01) when the upper limit number is 50 (hereinafter referred to as “basic lottery (L01: 50)”), the character (C0002) is set as the only ceiling character. The rare rank of the character (C0002) is 4 (see FIG. 4).

  When the character (C0002) is acquired as the ceiling character, the level of the character (C0002) is initially set to 1. In the basic lottery (L01: 50), there is one type of ceiling character, and only one character (C0002) can be acquired. In the basic lottery (L01: 50), any character is randomly selected from the character group with the character ID in the range of C0001 to C0500 by the restoration extraction method.

  In the basic lottery (L01: 80) when the upper limit number is 80, two characters of the character (C0002) and the character (C0013) are set as the ceiling characters. Both have a rare rank of 4. In the basic lottery (L01: 80), there are two types of ceiling characters and the number of ceiling characters that can be acquired (hereinafter referred to as “acquisable number”) is two.

  The level of the ceiling character (C0002) is initially set to 1, and the level of the ceiling character (C0013) is initially set to 3. In the basic lottery (L01: 80), one of the characters is randomly selected from the character group having the character ID in the range of C0001 to C0500 by the restoration extraction method.

  Since the basic lottery (L01: 80) has a higher upper limit than the basic lottery (L01: 50), the amount of game points consumed until the ceiling character is acquired (hereinafter referred to as “settlement consumption”) is large. Become. Instead, in the basic lottery (L01: 80), the number and level of ceiling characters are set more advantageously than the basic lottery (L01: 50).

In addition to the type of ceiling character, the number of obtainable characters, and the initial setting level, the advantage may be controlled by the evolution of the ceiling character. For example, the ceiling characters of the basic lottery (L01: 80) and the basic lottery (L01: 50) are both characters (C0002), but the basic lottery (L01: 80) is not a character (C0002) but an evolved character thereof. (C0008) may be obtained (see FIG. 4).
Alternatively, the character (C0008) may be acquired even in the basic lottery (L01: 50), but the character (C0008) may be acquired with a higher probability in the basic lottery (L01: 80).

  In the basic lottery (L01: 100), one of the characters is randomly selected from the character group having the character ID in the range of C0001 to C0400 by the restoration extraction method. In the basic lottery (L01: 150), one of the characters is randomly selected from the character group with the character ID in the range of C0600 to C1200 by the restoration extraction method.

  You may change the character which is a lottery object (population) according to an upper limit frequency | count. The character group included in C0600 to C1200 may be set to be more likely to acquire a rare character than the character group included in C0001 to C0400, or included only in the character range of C0600 to C1200. A rare character with a rarity level may be set.

  Depending on the maximum number of times, in other words, the balance between cost and return by changing the type and number of ceiling characters, the level at the time of acquisition, the number of characters that can be acquired, and the range of characters that are subject to lottery, depending on the amount of payment. Can be adjusted.

  A list of ceiling characters that can be acquired by the basic lottery is called a “privilege list”. Only the character (C0002) is registered in the privilege list of the basic lottery (L01: 50), and the character (C0019), the character (C0020), the character (C0021), and the privilege list of the basic lottery (L01: 150) are registered. Four characters (C0050) are registered.

When the count value (number of executions) reaches the upper limit number of times, the basic lottery execution unit 118 displays the privilege list and the obtainable number to the player via the U / I unit 122. The player selects as many characters as can be acquired from the ceiling characters registered in the privilege list. When the basic lottery (L01: 150) is executed, two characters can be selected from the character (C0019), the character (C0020), the character (C0021), and the character (C0050). On the other hand, the ceiling character when the basic lottery (L01: 50) is executed has no room for selection, and the character (C0002) is provided.
Note that the privilege list is not limited to when the count value reaches the upper limit number, and may be displayed to the player before the upper limit number is reached. It may be displayed before the upper limit count is determined, or may be displayed at a predetermined timing after the upper limit count is set, specifically, after a predetermined time from the determination of the upper limit count, or even when the execution count is displayed at the predetermined count. Good.

In the basic lottery (L01: 150), the lottery execution unit 114 may randomly select two characters from the ceiling characters registered in the privilege list.
The lottery execution unit 114 may determine whether to allow the player to select a character from the privilege list or to determine a character at random by sub lottery. The probability of the sub lottery may be set so that the player is more likely to be given a selection right as the upper limit number is larger, in other words, as the payment consumption is larger.

  A plurality of types of privilege lists may be set for one type of upper limit number of times. For example, the privilege list 1 and the privilege list 2 may be set for the basic lottery (L01: 100), and the lottery execution unit 114 may randomly select one. According to such a control method, it is not possible to know what character is available when the upper limit number is reached, so that it is easy to increase the player's expectation.

  Similarly, the lottery execution unit 114 may randomly select any one of a plurality of character ranges when the upper limit number is designated. For example, the character range 1 and the character range 2 may be set for the basic lottery (L01: 100), and the lottery execution unit 114 may randomly select one. Then, the basic lottery may be executed using the selected character range as a population.

FIG. 6 is a screen diagram of the upper limit selection screen 120.
When the player instructs execution of the basic lottery, the basic lottery execution unit 118 displays the upper limit selection screen 120 on the screen of the game terminal 104. On the upper limit selection screen 120, 50 times, 80 times, 100 times, 150 times and 200 times are shown as the upper limit times.
According to the upper limit selection screen 120 shown in FIG. 6, the rare rank of the ceiling character provided when the upper limit number is 50 is 4. When the upper limit is 80, two rare rank 4 characters are provided as ceiling characters. The player selects the upper limit number in consideration of the payment consumption (cost) of the game points required to reach the upper limit number and the type and number of ceiling characters (return) obtained when the upper limit number is reached.

In the upper limit selection screen 120 of FIG. 6, the upper limit number is a selection formula from five types, but the player may be able to manually select an arbitrary number such as 55 times or 56 times as the upper limit number.
The lottery execution unit 114 may randomly select one of the upper limit times from a plurality of upper limit times.

  When the basic lottery execution count (count value) reaches the upper limit count, the “settlement condition” is established, and the ceiling character is provided. The settlement condition is not limited to the count value and the upper limit number. For example, the settlement condition may be satisfied when the game point consumption amount when performing the basic lottery reaches a predetermined threshold. Further, a threshold may be set for the game point consumption speed. When the amount of game points consumed per unit time, for example, 5 minutes, reaches a predetermined threshold, the settlement condition may be satisfied. Such a threshold value (time and amount) may be selected or set by the player.

The player may select a character that the player wants and set a settlement condition such as an upper limit number of times according to the character. For example, when a basic lottery including the character 1 as a lottery target (population) or a basic lottery using the character 1 as a ceiling character, an upper limit number associated with the character 1 in advance may be set.
Further, the upper limit number (settlement condition) may be changed according to whether or not the player owns the character 1, the number of characters 1 held, the number of evolutions of the character 1, and the like.

FIG. 7 is a flowchart showing the basic lottery process.
When the player instructs execution of one of the basic lotteries at the game terminal 104, an instruction to execute the basic lottery is transmitted from the game terminal 104 to the game server 102. The basic lottery execution unit 118 displays the upper limit selection screen 120, and the settlement setting unit 116 sets the upper limit number (UL) according to the player's input (S10).

  The basic lottery execution unit 118 resets the count value (c) indicating the number of executions to zero (S12). The basic lottery execution unit 118 refers to the lottery setting storage unit 134 and executes the basic lottery based on the setting conditions (S14), and the lottery counting unit 140 increments the count value (c) (S16).

  If the count value (c) has not reached the upper limit number (UL) (N in S18), the process returns to S14. If the count value (c) has reached the upper limit number (UL) (Y in S18), the basic lottery execution unit 118 provides the ceiling character to the player (S20). Specifically, after selecting the ceiling character, the character information registered in the character information storage unit 132 is transmitted from the communication unit 110 to the game terminal 104, and the data processing unit 126 stores the character information in the data storage unit 128. sign up. As a result, the series of basic lottery processes is completed, and the next new basic lottery process can be started.

  In the present embodiment, the upper limit number is changed according to the player. The term “according to the player” here includes not only the case of being based on the input designated on the upper limit selection screen 120 by the player but also the case of automatic selection based on the player attribute.

Depending on the age of the player, a limit may be set on the number of executions of the basic lottery per day or per month. For example, it is assumed that the game consumption per month is limited to 5000 points in order to suppress the game point consumption of young people. Hereinafter, the basic lottery execution limit number per predetermined period is simply referred to as “limit number”. If the game point consumption required to execute the basic lottery once is 100 points, the limit number corresponding to 5000 points is 50.
Therefore, when the upper limit number is 200 times, this player needs four months to reach the upper limit number. In this case, it is much more difficult for the player to obtain the ceiling character than the player who has no restriction.

The settlement setting unit 116 may set the limit number to 50 and set the upper limit number to only 100 times or less when the player is young, for example, 15 years old or younger. According to such a control method, it becomes easier for younger players to control the game so that they can be enjoyed within a limited number of times.
The age may be self-reported to the player. The player inputs attribute information such as age when logging in, and registers the player attribute in the player information storage unit 130. The settlement setting unit 116 may determine a settable range of the limit count and the upper limit count according to the player attribute.

When the limit number of 15 years or younger is 50, the settlement setting unit 116 can select either 25 or 50 as the upper limit number. When the limit number of 20 years or younger is 100, the settlement setting unit 116 May be selectable as 50, 80, or 100 as the upper limit. If the player is 21 years old or older, the limit number may not be set. If the limit number of times of 10 years or younger is 30, the settlement setting unit 116 may fix the upper limit number to 25 times.
Similarly, the settable range of the upper limit number may be adjusted not only to suppress the game point consumption of the younger generation but also to suppress the game point consumption of the older generation.

  The game execution unit 112 may acquire the player attribute from contract information registered in the game terminal 104 in advance. Besides the age, the settable range of the upper limit number may be changed according to the game point consumption last month. For example, if the consumption of game points in the previous month is greater than a predetermined threshold, the settable range of the upper limit count may be suppressed in order to suppress the consumption of game points this month, and vice versa. The settable range may be expanded.

  The upper limit count or the selectable range of the upper limit count may be changed according to the play time, the number of login days, the number and type (rare rank) of the possessed characters, the progress of the game, and the player's remaining power for game points. It is considered that a player with a rich game experience can appropriately control the consumption of game points. The settlement setting unit 116 may determine that the game experience of the player is abundant when the play time or the number of login days is greater than a predetermined threshold.

The selectable range of the upper limit number of times may be set based on the level and type of the character required by the player, whether or not the player already has a ceiling character, and the like. When the player does not have the character 1, the upper limit of the basic lottery with the character 1 as the ceiling character is set to 100 times, and when the player has one character 1, the upper limit is set to 150 times. Good. When the character 1 has reached the maximum level, the upper limit may be set to 200 for the basic lottery in which the material character necessary for evolving the character 1 is the ceiling character.
According to such a setting method, the amount of payment for acquiring the character 1 for the first time is small, but the game characteristics can be controlled so that the second and subsequent acquisitions and the acquisition of the material character become difficult. That is, it is possible to realize a game property that is easy to acquire but difficult to align, and easy to acquire but difficult to train.

For players who have the ability to spend game points, for example, the model of the game terminal 104, the amount of data communication so far, game point information consumed in the past in the game, game point information consumed in other related games, It may be determined from such information.
The settlement setting unit 116 may increase the settable range of the upper limit number of times when it is determined that the player's spending power of game points is high.

  When the upper limit number is determined, another upper limit number may not be set until the count value reaches the upper limit number. Alternatively, the upper limit count may be changed midway (hereinafter referred to as “upper limit change”). For example, when the count value is 30 in the basic lottery (L01: 80), the upper limit change to the basic lottery (L01: 50) may be allowed. A cost may be imposed on the upper limit change. For example, instead of consuming 10 game points, an upper limit change may be permitted.

  By changing the upper limit number of times of basic lottery, if the character range to be drawn changes, the upper limit change may be a merit for the player. For example, when the target rare character A is won in the tenth lottery execution in the basic lottery (L01: 80), the player selects another rare character B rather than continuing the basic lottery (L01: 80) more than 70 times. You may want to challenge the basic drawing including L01: 50. For this reason, when changing the upper limit, the game balance may be maintained by imposing costs such as game point consumption.

The settlement setting unit 116 may determine the cost for changing the upper limit according to the rare rank of the character that is the lottery target. For example, when the target rare character A is won in the 10th lottery execution in the basic lottery (L01: 80), the average value of the rare ranks of the characters acquired up to the 10th basic lottery among the character groups to be drawn (or The higher the expected value, the larger the cost. The more rare characters that have been acquired in the basic lottery, the more in other words, the lower the average value of the rare ranks of characters that have not been acquired by the 10th basic drawing in the character group that is the subject of the lottery ( It is considered that as the number of characters decreases, the player wants to change the upper limit (change the basic lottery).
In such a case, a balance between the merit of the player and the cost (compensation) may be achieved by increasing the cost. Alternatively, when the player's intention to change the upper limit becomes stronger, the cost may be lowered and the upper limit may be changed.

  The basic lottery execution unit 118 may set basic lottery according to a request from the player, instead of preparing a plurality of types of basic lottery settings in advance. When the player needs a character (C0102), the basic lottery execution unit 118 may set a basic lottery including the character (C0102), or may set a basic lottery using the character (C0102) as a ceiling character. Good.

  The character that the player seeks does not necessarily have a high rare rank. For example, although the rare rank is not so high, there are characters that the player wants to add to the collection, and characters that the game developer did not expect may become popular. If the game operator sets such a character as a ceiling character, the player can easily attract the player to the basic lottery. While rare rank is high and rare characters that greatly affect the difficulty of the game and the world view, while maintaining rarity, you can get popular characters depending on game points even if there is not much influence May be set.

  Assume that the player needs both character 1 and character 2. Assume that the count value of the basic lottery with the character 1 as the ceiling character is 100 and the count value of the basic lottery with the character 2 as the ceiling character is 150. In this case, the settlement setting unit 116 may set a basic lottery that can acquire both the character 1 and the character 2 as ceiling characters. The settlement setting unit 116 may set the upper limit number to 200, which is smaller than 250 (= 100 + 150) which is the sum of both count values. A merit may be given to the player by making the upper limit count smaller than the total value of the upper limit count when the two types of basic lottery are individually executed.

According to the above setting, it is possible to give a merit to a player who requires both the characters 1 and 2 rather than the player who wants only the character 1. The player can be given an incentive to obtain various characters and evolve in various ways. In other words, the player can enjoy an incentive to enjoy the world view of the game.

In the case where the limit number of times is set based on the age or the like, a player with a smaller limit number of times becomes difficult to obtain a rare character. Therefore, when a player with a small number of restrictions and a player with a large number of restrictions, or a player with a small number of restrictions and a player who does not set the number of restrictions, a player with a small number of restrictions becomes disadvantageous.
As one solution, the exchange of players with different number of times of limitation may be prohibited. Specifically, the game execution unit 112 provides a game field in which only players under the age of 15 can participate, and a game field in which only players over the age of 15 can participate, isolate each game field, and have a different number of limits. You may control so that players cannot become friends. In addition, control may be performed so that players having different numbers of limits are not matched in the game.

  Alternatively, when there is a clear difference in ability between the player 1 and the player 2, a weak sword character may be given to the weaker player 1, or some of the characters possessed by the stronger player 2 play a battle. The ability difference may be adjusted by performing a process such as sabotage.

  In addition to the limited number of times, the game point consumption pace may be controlled by the execution frequency of the basic lottery. When the upper limit number is 100 times, the basic lottery can be executed up to 20 times per predetermined period (for example, one day), but when the upper limit number is 50 times, the basic lottery may be executed only up to 10 times per day. In this case, in any case, it takes at least 5 days to acquire the ceiling character. Since the number of days for acquiring the ceiling character does not change, it is possible to suppress an ability difference between players having different upper limit numbers. Especially for young players, it is difficult to increase the execution frequency of the basic lottery. Therefore, the upper limit number of times per day for other players may be controlled in accordance with the execution frequency of the young players. .

[Second Embodiment]
FIG. 8 is a data structure diagram of the count setting storage unit 136.
In the second embodiment, the number of executions does not always match the count value. When the basic lottery is executed once, the count value may increase by 1, may be 0.5, or may be 2. As described above, the increment of the count value when the basic lottery is executed once is referred to as “up value”. The up value in the first embodiment is fixed to 1, but the up value in the second embodiment varies.
In the second embodiment, in order to clarify that the number of executions does not always match the count value, the upper limit number is used instead of the upper limit number.

The game is identified by the game ID, and the attributes of each game are managed. In the second embodiment, not only a plurality of basic lotteries but also a count value is collectively managed among a plurality of games having the basic lottery as a component of the game. The count value in the second embodiment is characterized in that it becomes an “asset” of a player that can be used in a plurality of games.
The player can transfer the count value accumulated in game 1 to game 2. Alternatively, a count value (universal value) common to all games may be set, and the count value may be used in both the game 1 and the game 2.

  In FIG. 8, the up value of the basic lottery (L01) of the game (G01) (hereinafter referred to as “basic lottery (G01: L01)”) is set to 1. On the other hand, the up value of the basic lottery (G01: L02) is set to 1.5. In other words, the count value is easier to increase in the basic lottery (G01: L02) than in the basic lottery (G01: L01). If the upper limit is the same, the basic lottery (G01: L02) is advantageous to the player because fewer game points are required to acquire the ceiling character.

The average rare rank of the character group that is the lottery target of the basic lottery (G01: L01) is 4.3, and the average rare rank of the character group that is the lottery target of the basic lottery (G01: L02) is 4.1. The basic lottery (G01: L01) is easier to acquire a character with a higher rank, but the basic lottery (G01: L02) is easier to collect the count value. In other words, the payment amount up to the upper limit is less. Therefore, the game balance can be maintained while clarifying the individuality of the two basic lotteries.
What is necessary is just to set so that both correlation coefficients may become negative so that an average rare rank may become small, so that an up value becomes large.

When the basic lottery is executed, the lottery execution unit 114 may execute a lottery for selecting an up value from a predetermined range (hereinafter referred to as “up lottery”). Up lottery may be executed each time a basic lottery is executed, such as when determining an upper limit, when selecting a basic lottery, at the start of a game, at the first login of the day, at the time of game result notification, etc. The up lottery may be executed at an arbitrary timing.
Alternatively, the up lottery may be performed again after a predetermined period has elapsed after the up lottery. For example, the up lottery may be performed at the time of login, and the up lottery may be performed again one hour after the login. In addition, for example, an up lottery may be performed every day at 0:00 and notified at the time of login.
When a high up value is set in the up lottery, the player's motivation for the basic lottery is easily aroused.

In the basic lottery, when a character having a predetermined rare rank or higher, such as a character having a rare rank 5 or higher, is assigned, the basic lottery execution unit 118 may increase the up value. For example, when the upper limit of the basic lottery (G01: L01) is 50 (up value is 1), it is assumed that the character 1 of rare rank 7 is won in the 20th basic lottery (G01: L01). It is assumed that the rare rank of the ceiling character of the basic lottery (G01: L01) is 5. Since the player has obtained the valuable character 1, the player may lose the willingness to continue the basic lottery (G01: L01). At this time, the basic lottery execution unit 118 increases the up value from 1 to 3. When the up value is 1, in order to reach the upper limit in the basic lottery (G01: L01), another 30 lottery executions are necessary, but when the up value is 3, the number of lottery executions is only 10 times. Since the up value has increased, the player is given an incentive to perform the basic lottery (G01: L01) until the count value reaches the upper limit value.
Note that the same effect can be realized by adjusting the upper limit value from 50 to 30 instead of changing the up value.

The amount of change in the up value may be set according to the character level or the rare rank acquired in the basic lottery. For example, if a character with a rare rank 6 is assigned, the up value may be increased by 1 to change from 1 to 2, and if assigned to a character with a rare rank 7, the up value may be increased by 2 and changed from 2 to 4. . According to such a control method, the accumulated pace of the count value can be accelerated as the rare character is assigned in the basic lottery.
Although the details will be described later, since the count value also functions as a game asset of the player, such a control method makes it easier to arouse the willingness to continue the basic lottery.

The up value may increase or not decrease until reaching the upper limit value. Alternatively, the up value may be increased or decreased every time the basic lottery is executed. An up lottery may be executed within a range in which the up value is not a predetermined lower limit value, for example, 1 or less.
Also, when a rare character with a high rare rank is assigned, the up value may be increased, the up value may be increased when in a predetermined time zone or in a predetermined area, a predetermined character or a predetermined item You may increase the up value only when you have The probability that the up value is set high in the up lottery may be changed according to the possessed character and the player attribute.

  The lottery execution unit 114 may execute “evolution lottery” every time the basic lottery is executed. When the evolution lottery is won, an evolution character of the ceiling character may be set as a new ceiling character. In the evolution lottery, a winning probability of about 0.1% is set. According to such a control method, the player can expect not only the success / failure of the basic lottery but also the success / failure of the evolution lottery, so that the interest of the game can be deepened.

  In the evolution lottery, the ceiling character may be evolved in two or more stages at a stroke with a winning probability of about 0.01%. Also, a lottery for changing the ceiling character to another character more advantageous to the player, a lottery for changing the attribute value of the ceiling character to an advantageous setting for the player, a lottery for giving game points and items as bonuses in addition to the ceiling character, etc. Various ancillary lotteries may be performed.

FIG. 9 is a schematic diagram for explaining a count value exchange method.
In the second embodiment, the count value is shared among a plurality of basic lotteries and a plurality of games. In FIG. 9, it is assumed that a certain player has a count value 30. The up value (CU) of the basic lottery (G01: L02) is 1.5. In this case, the basic count value 30 corresponds to the count value 45 in the basic lottery (G01: L02). The fact that the up value (CU) of the basic lottery (G01: L02) is large means that the count value is easy to accumulate in the basic lottery (G01: L02), which is a kind of inflation state.

  On the other hand, since the up value (CU) of the basic lottery (G02: L01) is 0.5, the basic count value 30 corresponds to the count value 15 in the basic lottery (G02: L01). When the up value (CU) of the basic lottery (G02: L01) is small, the count value in the basic lottery (G02: L01) is difficult to accumulate, and therefore, a kind of deflation state occurs.

  In the basic lottery (G01: L02), the count value is easy to accumulate, so the value per count value is low. In the basic lottery (G02: L01), the count value is difficult to accumulate, so the value per count value is high. . For example, if the number of game points required to execute one basic lottery is 100 points, 100 points correspond to a count value of 1.5 in the basic lottery (G01: L02), but 100 in the basic lottery (G02: L01). Points correspond to a count value of 0.5. That is, the count value 1 in the basic lottery (G02: L01) has a value three times that of the count value 1 in the basic lottery (G01: L02).

  It is also possible to transfer the count value of the basic lottery (G01: L02) to the basic lottery (G02: L01). In this case, the replacement unit 144 replaces the count value 1 of the basic lottery (G02: L01) for every count value 3 of the basic lottery (G01: L02) because the exchange rate is 3: 1. However, the actual value does not have to be 3: 1, and the original value and the exchange rate may be deviated as in 3: 2 or 4: 1. Details will be described later.

  In this way, even when the value of the count value is different, transfer based on the real value of the count value can be performed in a plurality of basic lotteries or a plurality of games. For example, when the upper limit value of the basic lottery (G02: L01) is 50 and the upper limit value of the basic lottery (G01: L02) is 50, all of the held count values may be transferred to the basic lottery (G02: L01). According to such processing, it is possible to selectively allocate a resource called a count value to a basic lottery with a small amount of payment.

  The game server 102 may set a limited-time event and set a basic lottery that can be executed only during this period (hereinafter referred to as “event basic lottery”). In the event basic lottery, a rare character that is available only during the event period may be provided. If the count value can be transferred, the count value accumulated in the event basic lottery can be transferred to another basic lottery even when the event period ends. Since the count value of the basic event lottery is not wasted, the player can easily execute the basic event lottery with peace of mind.

  The event basic lottery up value may be set higher than the normal basic lottery. In this case, since the count value can be earned by the event basic lottery, it becomes easier to attract the player to the event basic lottery.

In FIG. 9, the exchange rate of the count value is set according to the up values of the two basic lotteries, but the exchange rate may not necessarily reflect the up value. For example, the exchange rate of the basic lottery (G02: L01) and the basic lottery (G01: L02) may be set to 4: 1 only during the campaign period instead of 3: 1. In this case, the strategy is to earn the count value firmly in the basic lottery (G02: L01) and shift to the basic lottery (G01: L02).
A basic lottery that easily accumulates count values instead of few rare characters and a basic lottery that hardly accumulates count values instead of many rare characters may be prepared.

  The exchange rate does not have to be fixed, and may be variable such as exchange rate. Depending on the popularity of the basic lottery and the rare rank of the character that is the subject of the lottery, the exchange rate may be changed at random. According to such a control method, it is possible to incorporate an arbitrage strategy that obtains a profit on the game by executing a more advantageous basic lottery with good timing as game characteristics.

  There is no need for one type of game point. For example, the basic lottery may be executed by consuming the item, or the basic lottery may be executed by canceling the character. In this way, there may be a plurality of types of game elements consumed to execute the basic lottery. Further, the up value or the upper limit value may be changed according to the type of game element.

  Not only the average rare rank, but an up value may be set according to the highest rare rank of the character to be drawn. For example, the up value of the basic lottery with the highest rare rank of 7 may be set to be higher than the up value of the basic lottery with the highest rare rank of 8. The up value may be set according to the average rare rank of the ceiling characters, the number of ceiling characters that can be acquired, and the like.

  Of the plurality of basic lotteries, a large up value may be set for a basic lottery in which the right to challenge is not given unless the game is sufficiently advanced. According to such a control method, it becomes easy to arouse continuation motivation for the game itself.

The up value may be changed according to the count value. For example, the up value may be increased or decreased as the count value approaches the upper limit value.
The up value of the basic lottery may be reduced as one basic lottery is executed more frequently. According to such a control method, it is advantageous not to execute only one basic lottery but to try various basic lotteries evenly.
The up value may be linked with the position information. For example, the up value may be increased only when the player is located in a partner store. Alternatively, the up value may be increased for a predetermined time when the player purchases the affiliated product. Note that the information that the player has purchased the affiliated product may be acquired by reading the information described in the receipt issued by the store with a terminal owned by the player.

  You may change an up value for every game instead of every basic lottery. For example, for a newly released game, the up value may be set high until the number of players who downloaded the game exceeds 100,000. Such a method makes it easier to collect participants in a new game at an early stage. Also, the up value may be set to a low value, and the up value may be set to a high value when the number of players who downloaded the game exceeds 1 million.

The game system 100 has been described above based on the embodiment.
According to the first and second embodiments, the selectable range of the upper limit number (upper limit value) can be set according to the player's selection or the player's attributes. The player can always acquire the ceiling character by executing the basic lottery until the upper limit is reached. For the ceiling character, the worst number of times can be limited to the upper limit number. Further, the rarity of a rare character that greatly affects the game balance can be maintained.

  When the upper limit number is small, the ceiling character's rare rank (merit to the player) is adjusted to be low, and when the upper limit number is large, the ceiling character's rare rank is set high, thereby reducing the cost of game point consumption and the return of the ceiling character. The game balance can be maintained by trying to balance.

  The character that the player wants does not necessarily match the important character that has a great influence on the progress of the game. Not only the character's strength but also various sensory elements such as design may increase the popularity of the character. The world view of the game is fostered not only by the game developer's settings, but also by the player's game interpretation. By setting the character preferred by the player as the ceiling character, it is possible to achieve both of the two propositions of maintaining the game balance and suppressing the worst consumption risk.

  In addition, this invention is not limited to the said embodiment and modification, A component can be deform | transformed and embodied in the range which does not deviate from a summary. Various inventions may be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments and modifications. Moreover, you may delete some components from all the components shown by the said embodiment and modification.

  Although it has been described that the game system 100 is configured by a plurality of game terminals 104 and one game server 102, some of the functions of the game terminal 104 may be realized by the game server 102, or the functions of the game server 102 may be A part may be assigned by the game terminal 104. In addition, a third device other than the game terminal 104 or the game server 102 may bear a part of the function. A set of each function of the game terminal 104 and each function of the game server 102 described in FIG. 2 can be generally grasped as one “information processing device (game device)”. How to allocate a plurality of functions necessary for realizing the present invention to one or a plurality of hardware depends on the processing capability of each hardware, the specifications required for the game system 100, and the like. It only has to be decided.

  The material character disappears due to the synthesis evolution, but after the disappearance, it may be changed to a game point or another character.

  The player may be given the right to perform basic lottery not only when the game points are consumed but also when some event condition such as victory of the battle is established. In the game, the character may be designed as a card or a figure. The character may be given as a present from another player, may be given by playing during an event period set by the game execution unit 112, or clears the game stage set by the game execution unit 112. It may be provided as a condition.

  The rare character 1 may be allocated in the basic lottery, or it may be obtained as a ceiling character. When the rare character 1 is obtained as a ceiling character, more game points are consumed than the winning acquisition, and in this case, some compensation may be performed.

For example, the basic lottery execution unit 118 accumulates experience values in the background every time the basic lottery is executed. And when the rare character 1 is acquired as a ceiling character, the accumulated experience value may be given to the rare character 1. On the other hand, when the rare character 1 is won and acquired, the accumulated experience value may be discarded. According to such a control method, the rare character 1 obtained as a ceiling character has a higher initial setting level at the time of acquisition.
Not only the experience value but also some additional benefits such as game points, items, character skill levels, and material characters may be provided.

The experience value to be given may be changed according to the count value accumulated until the rare character 1 is won. For example, when the rare character 1 is assigned in the first basic lottery, no experience value is added, and when the rare character 1 is assigned in the tenth basic lottery, the experience value is added only at the first value, and the 20th time. When the rare character 1 is assigned in the basic lottery, the experience value is added by a second value larger than the first value, and when the rare character 1 is acquired as the ceiling character, only the third value larger than the second value is added. Experience points may be added.
According to the above control method, even when a rare character 2 different from the ceiling character is assigned in the basic lottery, it is easy to provoke a willingness to continue the basic lottery in order to acquire the ceiling character 1. This is because it is attractive to the player that the ceiling character 1 is provided with many experience values.

  When the count value reaches the upper limit value, the upper limit value of the next basic lottery may be decreased. For example, when a basic lottery with an upper limit of 80 is selected, if the upper limit is reduced to 70, it becomes easier for the player to motivate the player to challenge the next basic lottery.

The advantage in the next basic lottery may be changed according to the average rare rank or the highest rare rank of the characters acquired in the basic lottery. For example, if the basic lottery is repeated until the upper limit is reached but a character with a rare rank of 5 or higher cannot be obtained, the upper limit of the basic lottery selected next time is reduced or the up value is increased. You may do. Alternatively, the winning probability of the rare character may be increased in the next basic lottery, or the level of the ceiling character may be increased.
According to such a control method, it becomes easy for a player who has not obtained the desired result in the basic lottery to be motivated to challenge the next basic lottery.

  If the character is disposed (discarded, sold, exchanged, etc.) within a predetermined time after assigning any character in the basic lottery, it can be assumed that the player is not satisfied with the character. Therefore, the dissatisfied points are added each time such a disposal action is performed, and when the dissatisfied points reach a predetermined value, the basic lottery setting conditions may be changed advantageously to the player.

  A count value or an experience value may be given to the player as a privilege in response to a login bonus or a friend application as a network game. For example, when the number of friends who enjoy the same game exceeds 10, the control may be performed to increase the count value or the up value.

  The up value may be changed according to the amount of game points consumed. For example, for a player with a large total consumption of game points, the basic lottery up value may be set high for a predetermined period or a predetermined number of times as a bonus. Or you may provide the count value and lottery right for 12 times, for example by consuming the game points for 10 times of basic lottery at once or within a predetermined period.

  Furthermore, the up value may be changed without the basic lottery according to the consumption of the game points. In this case, it is preferable to set the consumption amount of game points higher than when the basic lottery is involved.

FIG. 10 is a correlation diagram summarizing main mutual influence relationships of various parameters.
As described above, the basic lottery setting can be changed according to various conditions such as player attributes and possessed characters. Each element shown in FIG. 10 will be described.
Point type:
In addition to the game points obtained by billing, the game points, lottery tickets, items, characters, and other types of game elements to be consumed for executing the basic lottery are shown.
Holding status:
Indicates the type and number of characters held by the player, the amount of items and game points held.
Player attributes:
The player's profile, such as the player's age, sex, resources, and game experience, is shown.
Lottery result:
Indicates the type and value of the character obtained by the basic lottery.
Event:
In addition to events set in the game server 102, basic lottery and game popularity are also included.
Limit number of times:
Shows the basic lottery limit for a given period.
Maximum number of times (upper limit):
A count value required until a ceiling character is acquired is shown. Corresponds to payment consumption.
Lottery conditions:
The degree of expectation (advantage) about the basic lottery, such as the type of character to be drawn.
Up value:
Indicates the increment of the count value when the basic lottery is executed once.
Benefits:
When the count value reaches the upper limit value, it indicates the type and number of characters provided to the player or the possibility of selection. Not only a ceiling character but the privilege provided at the time of reaching an upper limit, such as an item and a game point, may be sufficient.
Exchange rate:
The exchange rate when shifting the count value between a plurality of games and a plurality of basic lotteries is shown.

For example, when the player is a young group (player attribute), the limit number is set low, and when the limit number is low, the selection range of the upper limit number (upper limit value) is limited. As shown in FIG. 10, the player attribute affects the limit number, and the limit number affects the upper limit number.
If the lottery result is not advantageous to the player, there are merits such as lowering the upper limit value of the next basic lottery and increasing the up value. As shown in FIG. 10, the lottery result affects the upper limit number, and the upper limit number affects the up value.
Each parameter shown in FIG. 10 is merely a result of selectively extracting the main ones in the present embodiment, and their relevance is not limited to that shown in FIG. 10, and various settings can be made.

The benefits provided as a result of the basic lottery are not limited to characters. For example, any item, game point, event ticket, or the like that will benefit the player may be used.
Although the basic lottery is described as restoration extraction, the present invention can also be applied to a non-restoration extraction method.

  Although it has been described that the upper limit number (upper limit value) is changed according to the player attribute or the like, the initial set value of the up value or the count value may be changed instead of the upper limit value. Expressed in a comprehensive manner, the game balance may be controlled by increasing or decreasing the amount of game point consumption (settlement consumption) required to reach the upper limit value depending on the player. For example, when the player has a small number of game points, the upper limit value may be set low, the count value may be started from 10 instead of zero while the upper limit value is fixed, and the up value is not 1 You may set to 1.5.

  The count value may be changed according to the amount of game points consumed. For example, even if the number of game points required to execute the basic lottery is 100 points, the drawing right may be given at 50 points for the first time. Instead, the count value may be set so that only 0.5, which is half of the normal value, is added. Further, the addition of the count may be changed between a case where the lottery is performed based on the consumption of game points and a case where the lottery is performed based on other than game points. For example, when a lottery is performed by consuming game points obtained by charging, the up value is 2, and when a lottery is performed by consuming game points or lottery tickets obtained by game results (obtained without charging) The value may be set to 1.

  The accumulated count value and experience value may be exchanged between players. For example, it is assumed that there is a player A who is seeking a rare character 1 that can be acquired by a certain basic lottery. Rare character 1 is not a ceiling character. When converted from the winning probability, it is assumed that the expected value of the count value assumed to acquire the rare character 1 is 500. However, even if game points are consumed and the basic lottery is repeated until the count value reaches 500, it is not known whether the rare character 1 can be obtained.

On the other hand, it is assumed that there is a player B holding the rare character 1. At this time, the player A may obtain the rare character 1 instead of giving the count value 600 minutes to the player B. Player A can reliably obtain the rare character 1 by passing the count value 600, and the player B can obtain many count values for the rare character 1.
In the present embodiment, game points, count values, and characters (privileges) are in a mutually interchangeable relationship. A character may be converted into a game point, or a count value may be converted into a character.

The following invention is recognized from the above description.
A1. A game execution unit that controls the progress of the game based on a game medium held by the player;
A basic lottery execution unit that executes a basic lottery with a winning probability assigned to each game medium and is based on consumption of game elements;
A setting unit that changes a consumption amount of game elements necessary for satisfying a predetermined condition depending on a player,
The basic lottery execution unit provides a privilege to a player regardless of a lottery result when the predetermined condition is satisfied.

  Regardless of the lottery result, when a predetermined condition such as the count value reaching the upper limit value is satisfied, the player may be provided with benefits such as game media and items. The benefit may be common to all players, but in this case, there is a possibility that the above conditions are unfair for the player 1 who is likely to satisfy the above condition and the player 2 who is difficult to be satisfied. One method is to divide the game fields of the player 1 and the player 2 (prohibiting player exchanges). In this case, the advantage of the player 1 does not affect the player 2.

  In the case where the same privilege is given to the player 1 whose condition is easily satisfied and the player 2 whose condition is difficult to be satisfied, the above condition is easily satisfied in the next basic lottery, such as setting a higher up value for the next basic lottery. You may set as follows. In the case of the player 1, instead of giving a privilege, the next basic lottery may be set so that the above condition is difficult to be satisfied, such as setting the up value of the next basic lottery low. Even if the benefits are the same, long-term balance may be achieved by differentiating the subsequent game difficulty levels.
