Meanwhile, free lottery specifications (free automatic selection specifications) are changed to specifications having content advantageous to the user who reaches the threshold to hold a lottery to the user who reaches the threshold during the (N+1)-th unit accounting period.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a server system that controls execution of a game including an automatic selection element based on a given automatic selection specification and a charging element.

  One of the attractions in online games is an automatic selection element that gives items that can be used in the game as prizes. For example, a lottery element for selecting a prize to be given by lottery is a representative example. Gamemakers are eager to improve the appeal of automatic selection elements. For example, when presenting information of items that can be prizes to the player, when the player acquires the parent item, by controlling the level of information disclosure related to the lottery so that the information of the child items can be disclosed, One technique is to increase the expectation of the lottery element (see, for example, Patent Document 1).

  On the other hand, advertisements and billing are inherent in the profit structure related to online games. For billing, for example, consideration for game play, purchase of items, paid lottery, and the like. As a payment method for charging, there are payment by electronic payment using a credit card, payment by virtual currency or items purchased by the player through the electronic payment or the like in advance. Such billing history information is managed in association with player identification information (for example, a player account), and a technique for controlling advertisement display is also known (for example, Patent Document 2).

  In a game including an automatic selection element, the automatic selection element plays an important role in enhancing the interest of the game, but on the other hand, problems related to charging are also pointed out. For example, one of the problems is that there is a player who repeatedly performs a pay lottery until the desired item is obtained and charges an excessively large amount. In particular, minor players were thought to tend to overcharge.

  As a simple countermeasure to deal with such problems, for example, an upper limit is set for the monthly charge amount, and after the charge upper limit threshold is reached, a paid automatic selection element (for example, lottery) or the like cannot be executed. Can be considered. However, in that case, the player who has reached the charging upper limit threshold value cannot enjoy the entertainment of the game related to the paid automatic selection element (for example, collecting items of special rarity, etc.) until the next month. The

  The present invention has been devised in order to provide a technique for providing a new interest caused by reaching the charge upper limit threshold.

A first invention for solving the above-described problem is a server system that controls execution of a game including an automatic selection element based on a given automatic selection specification and a charging element,

[Game description]
FIG. 2 is a diagram for explaining the outline of the game in the present embodiment.
The game of the present embodiment is an action RPG in which a player uses the main character 4 and the sub character 5 to fight the enemy character 6.

The game screen W2 includes a main display unit 21 and an operation icon display unit 22.
The main display unit 21 displays a state in which the main character 4 and the sub character 5 fight the enemy character 6.

  The main character 4 is a substitute in the game world of the player, and the attack power and defense power can be enhanced by equipping various items 7. Item 7 is an object that can be used in the game and is a game element in which various types are prepared. Item 7 is set with rarity (rareness / rareness), and the higher the rarity, the higher the ability is set. By allowing the main character 4 to equip or use an item with higher rarity, The game can be advantageously advanced.

  The sub-character 5 is an NPC (non-player character) that is automatically controlled to support the main character 4. The sub-character 5 can be obtained / obtained by a free lottery (an example of a free automatic selection element) per login, a loot in the game, a special event, or the like. The player can own a plurality of sub-characters 5, and can select and change a predetermined number of characters to be accompanied by the main character 4 from the sub-characters 5 owned before or during the game. The item 7 can be set so that the sub-character 5 can be equipped and used.

  The main character 4 and the sub character 5 have different abilities according to the progress of the game. The ability is managed by a control parameter value represented by a character level indicating the degree of growth, attack power, defense power, movement power, recovery power, skill, and the like. Of course, parameters other than these can be included as appropriate. When the main character 4 and the sub character 5 are equipped and used with items, their control parameter values are improved according to the effect setting of the item 7.

  From the player's point of view, it is necessary to obtain the item 7 with higher rarity and higher effect in order to advance the game without any difficulty. In turn, the collection of items 7 with higher rarity itself is an important factor in the fun of the game.

The free lottery icon 25 is an icon for inputting an execution operation of a free lottery (an example of a free automatic selection element) in which an item 7 that is inferior to a paid lottery but cannot be purchased through online shopping is included in the prize. is there.

[Description of Principle]
As a direct method for suppressing excessive charging of some players, there is an upper limit on the charging amount per unit accounting period divided by the accounting deadline (hereinafter simply referred to as “accounting closing date”). After the charging upper limit threshold is reached, the use of charging elements such as item purchases and paid lotteries may be limited until the end of the unit accounting period.

“Unit accounting period” includes one or more “unit periods”. Note that the unit accounting periods are not all the same time length.
The “unit period” can be set as appropriate depending on the game content and the game management mode. For example, a period that can be arbitrarily set by the game operator, such as 24 hours, holidays, 1 week, 10 days, 1 month, 2 months, etc. But you can.
The “accounting closing date (accounting closing date)” may be, for example, a closing date specified by a date such as the end of the month, a weekend, or the 15th of every month, or may be specified by a time from the beginning of the week or the previous closing time to a predetermined time. It may be the deadline date.
In this embodiment, the unit period is assumed to be one month on the calendar, and the unit accounting period is assumed to be the same one month.

  When the charging upper limit threshold is set, the player who has reached the charging upper limit threshold is not limited to pay lottery until the current unit accounting period (the unit accounting period including the current date and time; in this embodiment) ends. You can't even purchase items. The inability to pay lottery and purchase items for the player can greatly reduce the appeal of the game.

  Therefore, in this embodiment, as shown in FIG. 3, in the unit accounting period (N + 1th unit accounting period) following the unit accounting period (Nth unit accounting period: N is an integer) that has reached the charging upper limit threshold, The free lottery specifications will be changed to provide a new game appeal that can only be obtained if the billing limit is reached. In this embodiment, since the unit accounting period is one month, the free lottery specification is changed during the current month for a player whose total billing amount for the previous month has reached the billing upper limit threshold. This also leads to compensating for the decline in attractiveness that cannot be charged such as paid lottery or item purchase.

  Specifically, it is assumed that the total charge amount of the player 2 reaches a predetermined upper limit threshold on the X day of the Nth month. The player is referred to as a “threshold reaching player” or “threshold reached”. In this embodiment, the player who has reached the threshold cannot use item purchases or paid lottery until the Nth month after the Xth day. The specification of the free lottery executed by the player reaching the threshold in the Nth month remains the standard specification. However, in the (N + 1) th month, which is the next month, the specification of the free lottery executed by the threshold reaching player is changed from the standard specification to a special specification that is more advantageous to the player. The former is called “standard lottery” and the latter is called “specification change lottery”.

  FIG. 4 is a diagram for explaining an example of the lottery specification in the present embodiment, and is a diagram showing an example of the standard lottery definition data 521 that defines the standard lottery specification. The specification of the standard lottery according to the present embodiment includes a unique lottery ID 30, a lottery upper limit number 32 per day (also referred to as a unit period), a lottery upper limit number 34 until the end of the month (until the end of the unit accounting period), and one time. The number of prizes paid out per lottery 36 and a winning probability setting table 38 are described.

  The winning probability setting table 38 stores the winning probabilities in association with the types of prizes of the standard lottery. That is, in the standard lottery, a range of numerical values is set for each prize, a random number is generated each time the lottery is executed, and a prize in a range including the generated random number value is determined as a winning prize. The relative ratio of the numerical value range prepared for each prize type is the winning probability.

  Of course, the information describing the lottery specifications can be appropriately set unexpectedly. Further, in the example shown in the figure, the rarity is set to four stages of S, A, B, and C, and one type of premium is set for each rarity. However, the number of types of rarity and the types of premiums for each rarity are as follows. It can be set as appropriate.

  On the other hand, in the present embodiment, a plurality of types of specification change lotteries are prepared with differences in the degree of advantage indicating how much the player is more advantageous based on the standard lottery.

FIG. 5 is a diagram illustrating an example of the first specification change lottery definition data 522.
As with the standard lottery, the first specification changing lottery includes a unique lottery ID 30, a lottery upper limit number 32 per day, a lottery upper limit number 34 until the end of the month, a payout number 36, and a winning probability setting table 38. It is described by. However, in the first specification changing lottery, the winning probability of a prize satisfying a predetermined high rarity (a prize having a relatively high rarity) is improved as compared with that of the standard lottery. That is, it is changed advantageously for the player. In the example shown in the figure, the winning probabilities of the S rare and A rare prizes are increased, but the present invention is not limited to this. The type of rarity that increases the winning probability, the number of prizes of the rarity, and the amount to increase can be set as appropriate.

FIG. 6 is a diagram illustrating an example of the second specification change lottery definition data 523.
The second specification change lottery is more advantageous for the player than the first specification change lottery. Specifically, S rare and A rare prizes (premiums satisfying a predetermined high rarity) are added as compared to the standard lottery. In the example shown in the figure, the new S rare is added while keeping the winning probability of the entire S rare, and the new A rare is added with the same winning probability as the original A rare. The number, number and winning probability can be set as appropriate. The premiums added here (the S rare (2) premium and the A rare (2) premium in FIG. 6) are limited premiums that can be obtained only when the total charge amount reaches the upper threshold. It is preferable.

FIG. 7 is a diagram illustrating an example of the third specification change lottery definition data 524.
The third specification change lottery is set to be more advantageous for the player than the second specification change lottery. Specifically, the number of lottery upper limit 32 per day, the number of lottery upper limit 34 until the end of the month, and the number of payouts 36 are increased compared to the second specification changing lottery. These increases can be set as appropriate. Also, any one or two of the lottery upper limit number 32, the lottery upper limit number 34 until the end of the month, and the payout number 36 may be increased.

  FIG. 8 is a diagram showing an example of the nth specification change lottery definition data 525 (n is an integer of 4 or more). The nth specification change lottery is set to be more advantageous to the player than the third specification change lottery. Specifically, the lottery method is not the winning probability method (first lottery method) as shown in the first specification change lottery to the third specification change lottery, but the type and number of prizes and their payout order ( It is changed to a sequential payout method (second lottery method) determined in advance (not disclosed to the player). In short, it is an electronic version of a capsule toy vending machine, a so-called box gacha method.

  The specifications of the nth specification change lottery are described by a unique lottery ID 30, a lottery upper limit number of times 32 per day, a lottery upper limit number 34 until the end of the month, a payout number 36, and a payout order setting table 39. In the payout order setting table 39, a predetermined number of payout orders are stored in association with identification information of prizes to be paid out at that time.

  In the winning probability method, even if the winning probability of 1% is set for the S rare prize, the S rare prize is not necessarily won within 100 times. However, the sequential payout method is advantageous to the player because the S rare prize is absolutely one hit within 100 times.

  In addition, the kind of specification change lottery is not limited to these. In addition, the advantage for the player is not limited to this order, and a method for making the lottery advantageous for the player, such as improvement of the winning probability, addition of prizes, increase of the lottery upper limit number, increase of the number of payouts. Can be carried out singly or in combination of a plurality thereof. The order of the advantage of the lottery specifications for the player can be appropriately designed according to the content and combination thereof.

  FIG. 9 is a diagram for explaining the concept of determining which of a plurality of types of specification change lotteries prepared to apply. In the present embodiment, which one of a plurality of types of specification change lotteries prepared is to be adopted is determined based on the “play history” and “charging history” of the player. The play history is a record of when and how long the game has been played. The billing history is a record of when, what, and how much you paid.

  Specifically, the arrival days reference point P1, the arrival times reference point P2, the continuation number reference point P3, and the play frequency reference point P4 are obtained, and the size of the change point Pc, which is the total value thereof, is obtained. The specification change lottery to be applied is determined accordingly.

  The arrival days reference point P1 is determined by a predetermined function or table data based on the arrival days indicating how much time the charging upper limit threshold is reached from the start of the unit accounting period. The point is set to a higher value as the number of arrival days is smaller. In addition, the tendency shown with a graph is an example and can be set suitably.

  The arrival frequency reference point P2 is set to a higher value as the number of times the upper limit threshold is reached in the past. In addition, the tendency shown with a graph is an example and can be set suitably.

  The consecutive number reference point P3 is set to a higher value as the number of times the upper limit threshold is continuously reached in the past from the current unit accounting period (corresponding to the current month in the present embodiment).

[Description of operation]
Next, the flow of processing in the server system 1100 will be described. The processing flow described here is executed by the server processing unit 200s executing the server system program 501 and the server program 503.

  15 to 16 are flowcharts for explaining the flow of processing in the server system 1100 of this embodiment. First, as shown in FIG. 15, the server system 1100 executes a login process (step S2), and starts recording a play history and a charging history (step S4).

  Next, the server system 1100 prepares new play data 700 for the logged-in user (player) (see FIG. 13), and initializes the game progress control data 704 (step S6). Then, the server system 1100 reflects the game save data 609 of the user management data 600 (see FIG. 12) of the login player in the game progress control data 704 (step S8). At this time, the free lottery specification save data 614 is copied to the free lottery specification setting data 740 (see FIG. 12).

Next, the server system 1100 determines whether a specification restoration condition that is a condition for returning the free lottery specification to the initial state is satisfied (step S10). In the present embodiment, an affirmative determination is made when one unit accounting period ends, specifically, when a new accounting month is entered.
If the result is affirmative (YES in step S10), the free lottery specification setting data 740 is overwritten with the standard lottery definition data 521 (see FIG. 11) to return to the initial state (step S12).

Next, the server system 1100 starts game progress control (step S14).
Thereafter, the server system 1100 controls the movement of the main character 4 and the sub-character 5 to be used as the sub-character to be used in response to an operation input from the user terminal 1500, and controls the movement by causing the enemy character 6 to appear. To do.

  Next, the server system 1100 determines whether the lottery specification change triggering condition is satisfied (step S20). In the present embodiment, when a charge in the current unit accounting period is extracted from the charge history data 607 (see FIG. 12) of the user management data 600 of the player to calculate the total charge 710, the predetermined upper limit threshold is reached. Is determined as “affirmative”.

  If the result is affirmative (YES in step S20), the server system 1100 creates new threshold arrival history data 610 in the user management data 600 of the player (step S22; see FIG. 12).

Next, the server system 1100 determines whether the specification change for free lottery has been implemented for the player in the current unit accounting period (step S24).
Specifically, when the free lottery specification setting data 740 (see FIG. 13) is set to the specification change lottery according to the reflection of the save data in step S8, or the lottery specification change corresponding to the current unit accounting period is made to the player. If there is history data 612 (see FIG. 12), it is determined that the specification has been changed.

  If the specification change for the free lottery has not been performed for the player in the current unit accounting period (YES in step S24), the server system 1100 refers to the threshold arrival history data 610 of the player, and determines the previous unit. It is determined whether the total billing amount has reached the upper limit threshold during the accounting period (step S26).

  If the upper limit threshold has been reached (YES in step S26) and the number of persons subject to change in the current unit accounting period is less than or equal to a predetermined first-arrival upper limit (YES in step S28), the server system 1100. Adds an additional player to the change target person list 620 (see FIG. 11) by unit accounting period (step S30), and changes the specifications of the free lottery.

  In order to change the specification of the free lottery, first, the server system 1100 calculates a change point Pc (step S34; see FIG. 9). That is, the server system 1100 refers to the player's play history data 605 and billing history data 607 and calculates the change point Pc based on each function stored in the change point calculation function library 540.

  Moving to FIG. 16, the server system 1100 next refers to the specification change lottery selection table 550 (see FIG. 9) and determines the specification change contents of the lottery (step S36). Specifically, one of the first specification change lottery definition data 522 to the nth specification change lottery definition data 525 is selected. Then, the free lottery specification setting data 740 is overwritten with the selected definition data, and new lottery specification change history data 612 is added to the user management data 600 of the player (step S38).

  Next, the server system 1100 refers to the player's lottery specification change history data 612, and calculates the elapsed time from the first lottery specification change implemented for the player in the current unit accounting period (step S40). Then, the advantage of the free lottery specification is changed so as to decrease according to the elapsed time (step S42).

  Specifically, in the specification change lottery in which the winning probability is higher than the standard lottery (see FIG. 5), the winning probability of the high rarity prize that has been increased in the winning probability setting table 38 is slightly increased according to the elapsed time. Reduce. It may be gradually lowered according to the elapsed time, or may be lowered step by step. Alternatively, it may not be lowered.

In addition, in the specification change lottery in which the type of the prize is increased as compared with the standard lottery (see FIG. 6), the increased prize may be deleted from the winning probability setting table 38 according to the elapsed time. You may not delete it.
In addition, in the specification change lottery in which the lottery upper limit number of times 32 per day, the lottery upper limit number of times 34 until the end of the month, and the number of payouts 36 are increased (see FIG. 7), one or more of these values are set according to the elapsed time. It may be lowered. It may not be lowered.

  Such a decrease in the degree of advantage is not constant, and it may be determined how much it is decreased according to the charging history or play history of the player. Specifically, it is preferable that the rate of decrease of the advantage is relatively small as the number of arrival days 712 is short, and the rate of decrease of the advantage is relatively small as the number of arrivals 714, the number of consecutive times 716, and the play frequency 718 is large. is there.

  Then, the server system 1100 notifies the player that the specification of the free lottery has been changed advantageously for the player on the game screen and that the advantage gradually decreases toward the end of the month (step S44). The notification method can be set as appropriate. For example, a badge for attracting attention may be attached to the free lottery icon 25 on the game screen W2, and a pop-up that displays a notification content may be displayed when the player touches the free lottery icon 25. Alternatively, the notification text may be displayed in a band at the top or bottom of the screen.

Next, the server system 1100 detects an execution operation of a billing element (in this embodiment, item purchase and paid lottery) (YES in step S80), and if the total billing amount 710 has not reached the upper limit threshold (step (NO in S82), the requested charging element is executed and the charging process is performed (step S84). Along with this, the player's virtual account balance 603 and billing history data 607 (see FIG. 12) are updated.
On the other hand, if the total billing amount 710 has reached the upper limit threshold (YES in step S82), the server system 1100 restricts the use of the billing element and notifies the impossibility of executing the billing element (step S86).

Next, if a free lottery execution operation is detected (YES in step S100), the server system 1100 determines whether the free lottery restriction is met (step S102).
Specifically, referring to the free lottery execution history data 613 (see FIG. 12) of the user management data 600 of the player, the number of free lotteries executed on the day and the number of free lotteries executed on the current month are calculated. To do. Then, the lottery upper limit number 32 per day of the specification change lottery definition data indicated by the free lottery specification setting data 740 is compared with the lottery upper limit number 34 until the end of the month (see FIGS. 5 to 8).

If the restriction is not met (NO in Step S102), the server system 1100 executes the free lottery by applying the free lottery specification setting data 740, and adds the free lottery execution history data 616 of the player (Step S102). S104; see FIG.
On the other hand, if the restriction is met (YES in step S102), the server system 1100 notifies the player that the free lottery limit has been reached and cannot be executed (step S106).

Steps S20 to S102 are repeatedly executed until the game end condition is satisfied (NO in step S120).
The game end condition can be appropriately set according to the game content. For example, when a predetermined time elapses from the player character annihilation, the enemy character annihilation, or the play start date and time 702, it is possible to appropriately set the end of the game stage, the elapse of the predetermined time in the game world, and the like.

  When the game end condition is satisfied (YES in step S120), the server system 1100 updates the play history data 605, the game save data 609, and the free lottery specification save data 614 of the user management data 600 of the player (step S120). S122), a series of processing ends.

  As described above, according to the present embodiment, an upper limit can be set for billing as a measure against excessive billing. In addition, it is possible to compensate for a decrease in the interest of the game related to the charging element that cannot be obtained after the charging upper limit threshold is reached by changing the lottery specifications so that it is advantageous to the player.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The present embodiment is basically realized in the same manner as the first embodiment, except that the processing main body of the game progress control is the user terminal 1500. In the following, differences from the first embodiment will be mainly described, and the same components as those in the first embodiment will be given the same reference numerals and description thereof will be omitted.

  FIG. 17 is a functional block diagram illustrating a functional configuration example of the user terminal 1500B in the present embodiment. The user terminal 1500B of the present embodiment includes a game progress control unit 210 in which the game screen display control unit 262 is omitted. In other words, in the present embodiment, the user terminal 1500 executes calculation processing relating to the game progress by itself and generates a game space image by itself.

FIG. 18 is a diagram illustrating an example of programs and data stored in the terminal storage unit 500 of the user terminal 1500B according to the present embodiment.
The terminal storage unit 500 of this embodiment stores a terminal system program 502 and a game program 506. Then, as the game progress control unit 210 is processed by the user terminal 1500B, the game initial setting data 510 to the present excluding the user management data 600 and the change target person list 620 (see FIG. 11) by unit accounting period. The date and time up to 800 is stored in the terminal storage unit 500.

  The game program 506 is a program for causing the terminal processing unit 200 to realize the user terminal calculation unit 260 and the game progress control unit 210 of the present embodiment.

  The processing flow in this embodiment is basically the same as the processing flow (see FIGS. 15 to 16) of the server system 1100 in the first embodiment, and the game progress control unit 210 is executed by the user terminal 1500B. The execution subject of each step may be appropriately replaced with the server system 1100 or the user terminal 1500B. In addition, when executing a process that needs to refer to the user management data 600 such as login in the user terminal 1500B, whether to request the server system 1100 to provide necessary data and collate, or to request the process itself. To deal with.

According to the present embodiment, the same effects as those of the first embodiment can be obtained.
The user terminal 1500 </ b> B may not be responsible for all of the game progress control unit 210, but may be limited to a part thereof.

[Modification]
As mentioned above, although embodiment which applied this invention was described, the form which can apply this invention is not limited to the said form, A component can be added, abbreviate | omitted, and changed suitably.

[Part 1]
For example, in the above-described embodiment, an example in which an online game is realized by a client-server type computer system has been described. However, it may be realized by a computer system in which a plurality of user terminals 1500 are connected by peer-to-peer connection. In that case, the function as the server system 1100 of the first embodiment is assigned to any user terminal 1500. Or it is good also as a structure which divides and bears the function which the game progress control part 210 has with several user terminals 1500 like 2nd Embodiment.

[Part 2]
Furthermore, although the online game is exemplified in the above embodiment, the present invention can be similarly applied to a game executed by the user terminal 1500 in a stand-alone manner, in other words, a game executed in a computer system including a single computer. In this case, basically, the functional configuration shown in FIGS. 10 and 17 may be read as that realized by the user terminal 1500 alone.

[Part 3]
For example, in the above-described embodiment, the action RPG is taken as an example of the game genre. However, the game genre is not limited to this and can be appropriately set as long as the game includes a charging element and a lottery element. For example, the present embodiment can be applied to a puzzle game, a tactical simulation game, a shooting game, a love game, a training game, a race game, a puzzle game, an action game, a music game, a sports game, and the like.

[Part 4]
In the above embodiment, the specification of the free lottery is changed. However, for example, in the case where the free lottery is not prepared in the first place, the specification of the pay lottery may be changed. Specifically, when the total billing amount 710 reaches the upper limit threshold value, the billing amount for the lottery execution consideration in the pay lottery specification may be changed to “0”. Alternatively, the lottery execution consideration is changed to the use of a predetermined “dedicated pass item” or “dedicated ticket item”, and those items that are valid only in the current unit accounting period are separately given to the players detected as users reaching the threshold value It is good.

[Part 5]
In the above-described embodiment, the definition of the winning probability formula specification change lottery is prepared in advance. However, the present invention is not limited to this (see FIGS. 5, 6, and 7). For example, the maximum number of lotteries per day 32, the maximum number of lotteries 34 until the end of the month, the number of payouts 36, and the winning probabilities associated with each prize in the winning probability setting table 38 are the number of days reached 712, the number of times reached 714, 716 and a function (or table data) including a play frequency 718 as parameters, and each of the lottery upper limit number of times 32 per day, the lottery upper limit number 34 until the end of the month, the number of payouts 36, and the winning probability setting table 38 each time. The winning probability associated with the prize may be calculated and determined.

[Part 6]
In the above embodiment, for a player whose unit accounting period is one month and the total charge amount of the previous month has reached the charge upper limit threshold, the free lottery specification is changed in the next month, but it is detected that the charge upper limit has been reached. The relationship between the unit accounting period and the unit accounting period in which the specification of the free lottery is changed is not limited to this. That is, the relationship is not limited to immediately before and after the previous month and the current month, but may be a relationship between two months ago (or a month before that) and the current month.

[Part 7]
Moreover, in the said embodiment, although the period which changes a specification was made into the unit accounting period of 1 unit, it is not restricted to this. Multiple unit accounting periods can also be used. For example, the number of unit accounting periods determined based on the change point Pc (see FIG. 9) and the parameter values (the number of days reached, the number of arrivals, etc.) referenced to calculate the change point Pc can be changed. The length of the unit accounting period as the effective period of the specification change can be determined according to the condition of the effective period.

[Part 8]
In the above embodiment, in principle, the lottery method of the lottery element is the winning probability formula (first lottery method), and when the specification is changed to the nth specification changing lottery, it is sequentially changed to the payout method (second lottery method). As explained to be. However, all the lottery elements are sequentially paid out (second lottery method), and the type and number of prizes are (N + 1) when the total billing amount does not reach the billing upper limit threshold and (N + 1) after reaching the Nth unit accounting period. ) Number unit accounting periods may be different.

  That is, the automatic selection element is an element that automatically selects and gives a prize from a predetermined limited number of prize groups according to a player's instruction operation, and the prize group from which the automatic selection element is selected Is changed to a different specification between the case where the total charge amount does not reach the charge upper limit threshold and the (N + 1) th unit accounting period after reaching the Nth unit accounting period. It can be said that the contents of the box in the so-called box gacha change.

[Part 9]
For game elements other than the lottery element (automatic selection element), the case where the total charge amount does not reach the charge upper limit threshold and during the (N + 1) th unit accounting period after reaching the Nth unit accounting period. You may make it change into a different specification. For example, during the game, NPCs (non-playable characters) such as brokers, buyers, merchants, etc. who exchange and trade items and characters are introduced, and game elements that exchange these goods and trade are incorporated. Then, the exchange rate for barter exchange and trading is changed between the case where the total charge amount does not reach the charge upper limit threshold and the (N + 1) th unit accounting period after reaching the Nth unit accounting period. It is good as well. In addition, as a lottery element using items as consumption media rather than bartering or buying / selling, the consumption amount of consumption media required for one lottery is calculated when the total billing amount does not reach the billing upper limit threshold. It may be changed between the (N + 1) th unit accounting period after reaching the unit accounting period.

[Part 10]
In the above-described embodiment, the lottery specification is changed during the (N + 1) th unit accounting period for users whose total charging amount in the Nth unit accounting period has reached the charging upper limit threshold (threshold reaching user) (hereinafter, “ This is referred to as “the first change”. In addition to this, the lottery specification may be changed (hereinafter referred to as “second change”) until the accounting closing date (accounting closing date) related to the Nth unit accounting period has passed. The specification according to the second change may be the same as or different from the specification according to the first change. For example, for the first change, the specification to be changed is determined based on all or some of the points P1 to P4 described above, and for the second change, the points P1 to P4 described above are determined. It is good also as determining the specification changed using all or a part of them. Of course, the content of the specification to be changed may be different.
