Here, m and n are integers of 1 or more such that m> n, for example. Preferably, mn is an integer of 2 or more. The lottery processing unit 612 performs a second lottery process for allowing the user to acquire (acquire) the remaining n game media out of the m game media. That is, first, a first lottery process for lottering (mn) game media from the game media group serving as a population is performed. Then, the user is made to acquire (mn) game media hit by the first lottery process. Then, a second lottery process for drawing the remaining n game media is performed.

  At this time, the lottery processing unit 612 performs a lottery process for determining k candidate game media in the second lottery process. For example, k candidate game media are selected from a group of game media as a population to determine k candidate game media. Then, the lottery processing unit 612 performs processing for causing the user to acquire (acquire) n game media designated (selected) from the determined k candidate game media. In other words, in the second lottery process, k candidate game media are drawn from the second game media group, but n game media are determined from the k candidate game media. It is not based on a lottery but based on a user designation (selection). For example, k candidate game media (game media images) determined by lottery are displayed on the display unit 190 of the terminal device TM, and n game media are selected from the k candidate game media by the user. Let me choose. Then, the user is made to acquire the n selected game media.

  In this way, (mn) game media are acquired by the user through the first lottery process, and the remaining n game media are acquired through the second lottery process. Then, the registration processing unit 613 registers a total of m (= (mn−n) + n) acquired game media as user-owned game media. That is, the acquired m game media are stored in the owned game media information storage unit 673 in association with the user information and registered.

  In the first lottery process, the lottery processing unit 612 performs a process of lottering (mn) game media from the first game media group. For example, a process of randomly drawing (mn) game media from the first game media group as a population based on, for example, a probability table or the like is performed. On the other hand, in the second lottery process, a process of drawing k candidate game media from the second game media group is performed. For example, a process of randomly drawing k candidate game media from the second game media group, which is a population different from the first game media group, based on, for example, a probability table or the like. In other words, the game media group serving as a population from which (mn) game media are extracted is different from the game media group serving as a population from which k candidate game media are selected. For example, in the second game media group, more rare game media and game media having higher parameter values (ability parameter values) are included than in the first game media group.

  In addition, the lottery processing unit 612 changes the number k of candidate game media in the second lottery process. For example, in the second lottery process, k candidate game media are determined by lottery, and the number k is changed variably. In this case, the number k may be set by the user's selection, or the number k may be automatically determined. Alternatively, the number k is set according to the game situation of the user, the number k is set according to the level of the user, or the number k is set according to the charge amount for the user (the amount of consideration paid for the charge). It may be set. The lottery processing unit 612 selects a game medium having a higher rarity as a candidate game medium as the number k is smaller. Here, various aspects such as common, uncommon, rare, and super rare may be considered as the rare degree (rare degree). For example, when the number k is small, the probability that a game medium with a higher degree of rarity will be hit or a game medium with a higher degree of rarity will be hit as compared with the case where the number k is large. Further, when the number k is small, the probability that a game medium having a high parameter value (ability, etc.) will be hit or a game medium having a high parameter value will be hit, as compared with the case where the number k is large.

  The lottery processing unit 612 determines the number k based on user input information. For example, the user inputs input information for determining the number k at the terminal device TM. For example, on the selection screen displayed on the display unit 190 of the terminal device TM, the user operates the operation unit 160 to determine the number k. Then, the number k of information is transmitted to the server system 500, and the lottery processing unit 612 determines the number k based on the received number k of information. As described above, the number k may be automatically determined by the server system 500, or the number k is determined according to the game situation of the user, the level of the user, the amount charged to the user, and the like. Also good.

  In addition, the lottery processing unit 612 draws k candidate game media from the lottery probability in the second lottery processing and the second game media group according to the lottery result in the first lottery processing. At least one of the settings of the second game media group is changed. For example, the lottery probability in the second lottery process is changed depending on what kind of game media are (mn) game media lottery lottery in the first lottery process, The setting of the second game media group is changed. The lottery probability in the second lottery process is, for example, the probability that a game medium with a high degree of rarity or a game medium with a high parameter value will win in the second lottery process. The setting of the second game media group may be, for example, setting of the number or ratio of game media having a high degree of rarity or a game parameter having a high parameter value, setting of the level of rarity, or any game media as the second game media group For example, whether to select a group.

  Also, the lottery processing unit 612 draws k candidate game media from the lottery probability in the second lottery process and the second game media group according to the situation of the game media owned by the user. At least one of the settings of the second game media group is changed. The situation of the user-owned game media is, for example, the number or ratio of game media with a high degree of rarity or game parameters with a high parameter value in the user-owned game media, or a predetermined type (attribute) of the user-owned game media. The number and ratio of game media.

  In addition, the lottery processing unit 612 draws k candidate game media from the lottery probability in the second lottery process and the second game media group according to the history information about the game media owned by the user. At least one of the settings of the second game media group is changed. The history information on the user's owned game media is a history of operations performed on the owned game media by the user. For example, it is a history of operations such as deletion, composition, exchange, use or acquisition of owned game media.

  In addition, the lottery processing unit 612 determines the number k of candidate game media or the number n of game media obtained in the second lottery process according to at least one of the number of executions and the execution interval of continuous acquisition of m game media. Change. For example, whether the number of continuous acquisitions of m game media is large or small, whether the continuous acquisition interval is short and frequent, or whether the execution interval is long and frequent In response to the above, the number k of candidate game media is increased or decreased, or n, which is the number of game media acquired in the second lottery process, is increased or decreased.

  In addition, although the case where the server system 500 of FIG. 2 performs the reception process, the lottery process, the registration process, the game process, the management process, and the like of the present embodiment has been described above, the present embodiment is not limited to this. For example, the terminal device TM in FIG. 3 may perform part or all of the reception process, the lottery process, the registration process, the game process, the management process, and the like of the present embodiment described above. In this case, the terminal device TM (or a system in which the terminal device and the server system cooperate) functions as the game system of this embodiment.

2. Next, the method of this embodiment will be described in detail. In the following description, the case where the game media to be subjected to the lottery process is a character card will be mainly described as an example, but the present embodiment is not limited to this. For example, as a game medium, an item card that is an electronic card other than a character card, or various game play elements such as an item, a character, or an avatar can be used. Hereinafter, the server system 500 is simply referred to as a server as appropriate.

2.1 First and Second Lottery Processing FIG. 4 is a sequence diagram for explaining the method of this embodiment. First, the terminal device makes a continuous acquisition request to the server for m character cards (game media in a broad sense; hereinafter the same). For example, on the screen displayed by the web brother in the terminal device, the user inputs a continuous acquisition request for m character cards. This m character card continuous acquisition request corresponds to a so-called continuous gacha (continuous gacha) execution request. In response to such a request for continuous acquisition of m character cards, the server performs billing for requesting payment of the in-game currency for the m character cards (in the case of a pay gasha).

  And a server performs the lottery process (1st lottery process) for making a user acquire (mn) character cards among m character cards (m pieces) (step S1). For example, a lottery process such as randomly selecting a character card from a character card group based on a probability table or the like is performed.

  Next, the server performs a lottery process for determining k (k) candidate character cards (candidate game media in a broad sense) (step S2). For example, a lottery process such as randomly selecting k candidate character cards from the character card group based on a probability table or the like is performed.

  Then, when k candidate character cards are determined in this way, images of these k candidate character cards are displayed on the user terminal device, and designation (selection) of the character card by the user is accepted. Then, n (n) character cards designated by the user among the k candidate character cards are determined as character cards to be acquired by the user (step S3). In this way, a total of m character cards are acquired by the user from the (mn) character cards in step S1 and the n character cards in step S3. Then, the acquired m character cards are registered as user-owned character cards (step S4).

  FIG. 5 is a diagram for explaining the method of this embodiment in more detail. FIG. 5 is an example in which m, n, and k in FIG. 4 are m = 11, n = 1, and k = 5, respectively. However, m, n, and k are not limited to this. For example, m may be increased or decreased, n may be increased to 2 or more, and k may be increased or decreased.

  FIG. 5 corresponds to a so-called 11 continuous gasher. In the normal 11 consecutive gashes, the user can acquire 11 character cards by performing the lottery processing 11 times consecutively by performing only one gasha play operation. In this case, the user is charged for 11 sheets. That is, the user needs to pay 11 in-game currencies (virtual currency) as a consideration for 11 consecutive gasha gameplay. For example, the last eleventh character card is also determined by a lottery process. The character card has a higher degree of rarity or a higher ability parameter value than the ten character cards acquired before that. Appears. Therefore, the user is motivated by the acquisition of a character card with a high degree of rarity or a character parameter with a high parameter value in the last eleventh card, and plays 11 consecutive gashes.

  On the other hand, in this embodiment, an element designated by the user (selection) is taken into the last one character card. Specifically, when the user performs an operation of continuously acquiring (successive acquisition, continuous provision) of 11 character cards as in 11 continuous gashas on the terminal device, the payment is made for 11 in-game currencies. The continuous acquisition request is accepted. Then, as shown by A1 in FIG. 5, a lottery process (first lottery process) of mn = 11−1 = 10 character cards is performed. In FIG. 5, ten character cards CD1 to CD10 are acquired by the lottery process. These ten character cards CD1 to CD10 are, for example, normal character cards that are not high in rarity and low in parameter values such as ability.

  In order to determine the last n = 1 character card, in this embodiment, for example, a lottery process of k = 5 candidate character cards is performed as shown in A2 of FIG. This lottery process is performed as the second lottery process of the present embodiment. In FIG. 5, five candidate character cards CC1 to CC5 are won by this lottery process. These candidate character cards CC1 to CC5 are character cards that have a higher degree of rarity or a higher parameter value such as ability than the character cards CD1 to CD10 that are won in the A1 lottery process.

  The images of the five candidate character cards CC1 to CC5 won by the lottery process of A2 in FIG. 5 are displayed on the user terminal device. Then, as shown at A3, the user designates n = 1 character card desired by himself / herself from among these candidate character cards CC1 to CC5. That is, a selection frame of five candidate character cards CC1 to CC5 is provided, and the user can select a favorite character card from the selection frame. Among these candidate character cards CC1 to CC5, there are cases where a character card (super rare) with a very high degree of rarity or a character card with a very high parameter value is included. Specify a character card. Alternatively, the user may be aiming for a complete (complete gasha) of aligning a specific series of character cards (a specific type of character card). In this case, if there is a missing character card in the series (types) collected by the user among the candidate character cards CC1 to CC5, the character card is designated.

  In this way, the user designates n = 1 character card from the candidate character cards CC1 to CC5. Then, m = 11 character cards including mn = 10 character cards CD1 to CD10 acquired in the lottery process of A1 and n = 1 character card designated as shown in A4. As shown in A5, it is registered as a user-owned game character card.

  As described above, in this embodiment, when the user performs a lottery play for 11 consecutive acquisitions of character cards, 10 (mn) character cards are determined by a lottery process as in the case of 11 consecutive gashas. On the other hand, for the remaining one (n) character cards, first, five (k) candidate character cards are selected by a lottery process. Then, the user can select one favorite character card from among these five candidate character cards, so that a total of 11 character cards can be acquired as owned character cards. Therefore, unlike the 11 consecutive gashas in which all 11 character cards are selected by the lottery process, the last one (n) character cards can be used to reflect the user's intention of selection (select). Gasha) can be realized. In this way, for example, users who are aiming to collect character cards with a high degree of rarity or character values with high parameter values, or users who are aiming to complete a specific series of character cards, etc. It is possible to improve the degree of immersion and enthusiasm of the user's lottery play.

  FIG. 6 is an explanatory diagram of the detailed operation of the present embodiment. In FIG. 6, in the first lottery process for determining 10 character cards out of 11 character cards that are continuously acquired, as shown in B <b> 1 and B <b> 2, 10 characters are selected from the first game media group. A process of drawing lots of (mn) character cards CD1 to CD10 is performed. On the other hand, in the second lottery process for determining the remaining one (n) character cards out of the 11 character cards that are continuously acquired, as shown in B3 and B4, the second game media group A process of drawing lots (k pieces) of candidate character cards from among them is performed. Then, one (n) character card designated by the user from these five candidate character cards is acquired as the last character card of the eleven cards.

  Here, the first character card group that is the population in the first lottery process shown in B1 and the second character card group that is the population in the second lottery process shown in B2 are different from each other. It is a character card group.

  As an example, the first character card group is, for example, a character card group with a low appearance probability of a rare character card or a small number (ratio) of rare character cards. Alternatively, the character card group has a low appearance probability of a character card having a high parameter value (a parameter value of an ability such as attack power, defensive power or physical strength) or a small number of character cards having a high parameter value.

  On the other hand, in the second character card group, for example, the appearance probability of a rare character card is higher than that of the first character card group, or the number (ratio) of rare character cards is higher than that of the first character card group. It is a character card group. Alternatively, the character card group has a high appearance probability of a character card having a high parameter value or a large number of character cards having a high parameter value. For example, in the present embodiment, a second character card group that is a dedicated line-up is provided as the character card group for the second lottery process.

  In this way, the five candidate character cards CC1 to CC5 selected from the second character card group have higher rarity or parameter values than the character cards CD1 to CD10 selected in the first lottery process. Becomes a high character card. And since the user can select his / her favorite character card from among the candidate character cards CC1 to CC5 having a high degree of rarity or a high parameter value, it is possible to further increase the user's degree of immersion and enthusiasm for the lottery play. become.

2.2 Various Processing Examples Next, various processing examples of this embodiment will be described.

  For example, in the present embodiment, the number k (number k) of candidate character cards can be changed in the second lottery process for determining candidate character cards.

  For example, as shown by C1 in FIG. 7, k = 2 candidate character cards CC1 and CC2 are selected in the second lottery process. Then, as shown in C2, the user designates one (n) character card from k = 2 candidate character cards, and the designated character card is acquired as the 11th last character card. Become so.

  In FIG. 8, as indicated by D1, k = 10 candidate character cards CC1 to CC10 are selected in the second lottery process. Then, as shown in D2, the user designates one (n) character card from k = 10 candidate character cards, and the designated character card is acquired as the 11th last character card. Become so. In this way, the number k of candidate character cards can be changed in various ways according to various situations, and various situations, requests, etc. can be handled.

  In this case, in the present embodiment, the number k shown in C1 of FIG. 7 and D1 of FIG. 8 can be determined based on user input information. For example, when the user performs an operation of determining the number k in the terminal device, the determined k candidate characters are drawn in the second lottery process. In this way, it is possible to reflect the user's intention in determining the number k. However, the system side may automatically determine the number k. Alternatively, the number k is determined according to the game situation of the user, the number k is determined according to the level of the user's game, or the number k is determined according to the amount paid by the user for the charge. May be. That is, the number k is changed in accordance with the user's game situation, level, charge amount, and the like.

  In the present embodiment, for example, as the number k is smaller, a character card having a higher degree of rarity may be selected as a candidate character card. For example, FIG. 9 shows an example of the relationship between the number k and the appearance probability of the rare character card in the second lottery process. In FIG. 9, the smaller the number k, the higher the appearance probability of the rare character card in the second lottery process. In this way, in the second lottery process, as the number k is smaller, a candidate character card with a higher degree of rarity is selected by lottery.

  For example, as shown in C1 of FIG. 7, when the number k is as small as two, a character card having a high degree of rarity as the candidate character cards CC1 and CC2 is won by the second lottery process. Accordingly, the user can designate a favorite character card from among the candidate characters cards CC1 and CC2 having a high degree of rarity, and can meet the demands of users who are aiming to collect character cards having a high degree of rarity. it can. For this reason, for example, when the user can select the number k, the user who aims to collect character cards with a high degree of rarity selects a small number as the number k.

  On the other hand, as shown in D1 of FIG. 8, when the number k is as large as 10, the character cards having a lower rarity than the C1 of FIG. 7 are selected as the candidate character cards CC1 to CC10 in the second lottery. It becomes hit by processing. However, in D1 of FIG. 8, since the number of candidate character cards is increased as compared with C1 of FIG. 7, the range of user selection is expanded. Therefore, for example, for a user who aims to complete a specific series, the possibility that a character card corresponding to the specific series (a specific type of character card) is included in a large number of candidate character cards increases. Therefore, it is possible to meet such a user request. For this reason, for example, when the user can select the number k, a user who aims to complete a specific series selects a larger number as the number k.

  Moreover, in this embodiment, according to the lottery result in the first lottery process, the lottery probability in the second lottery process or the k candidate character cards from the second character card group is lottery. At least one of the settings of the second character card group can be changed.

  For example, in FIG. 10, as indicated by E1, ten (mn) character cards are drawn by the first lottery process. In this case, according to the result of the first lottery process shown in E1, as shown in E2, the lottery probability in the second lottery process for lottering five (k) candidate character cards is changed. Or based on the result of the 1st lottery process shown to E1, as shown to E3, the setting of the 2nd character card group at the time of drawing 5 candidate character cards is changed.

  For example, in the first lottery process shown in E1, for example, a character card with a high degree of rarity or a character card with a high parameter value (attack power, defense power, physical strength, etc.) is not hit, only character cards called normal cards or small fish cards are hit. Suppose that it was a bad lottery result, such as being selected. In this case, the lottery probability in the second lottery process indicated by E2 is increased. For example, the probability of winning a rare character card or a character card having a high parameter value is increased. Alternatively, the setting of the second character card group indicated by E3 is set to be more advantageous for the user. For example, as the second character card group, a character card group having a high appearance probability of a rare character card or a character card having a high parameter value, or a character card group having a large number of rare character cards or a character card having a high parameter value is used. To do.

  On the other hand, in the first lottery process indicated by E1, it is assumed that the lottery result is good, for example, a character card having a high degree of rarity or a character card having a high parameter value is won. In this case, the lottery probability in the second lottery process indicated by E2 is lowered. For example, the probability of hitting a rare character card or a character card having a high parameter value is lowered. Or the setting of the 2nd character card group shown to E3 is made more unfavorable for a user. For example, as the second character card group, a character card group having a low appearance probability of a rare character card or a character card having a high parameter value, or a character card group having a small number of rare character cards or a character card having a high parameter value is used. To do.

  Also, in the first lottery process shown in E1, it is assumed that the lottery result indicates that the number of character cards of a specific series that the user is aiming for completion is small among the ten selected character cards. In this case, in the setting of the lottery probability of E2, the probability that the character card of the specific series will win is increased. Alternatively, in the setting of the second character card group shown in E3, a character card group having a high probability of being hit by the specific series of character cards or a character card group having a large number of character cards of the specific series is used. .

  On the other hand, in the first lottery process shown in E1, it is assumed that the lottery result indicates that among the selected 10 character cards, the number of character cards of a specific series that the user is aiming for completion is large. In this case, in the setting of the lottery probability of E2, the probability that the character card of the specific series is hit is lowered. Alternatively, in the setting of the second character card group shown in E3, a character card group having a low probability of being hit by the specific series of character cards or a character card group having a small number of character cards of the specific series is used. .

  As described above, FIG. 10 employs a technique of changing the lottery probability in the second lottery process and the setting of the second character card group in accordance with the result of the first lottery process. In this way, the five candidate character cards for designating the eleventh character card are affected in the occurrence rate of rare character cards by the lottery result of the previous ten character cards. become. For example, five candidate character cards are drawn from the second character card group that has a high or low rare character card count depending on the result of lottery of the previous 10 character cards. Further, when the ten character cards drawn in the first lottery process are not very good character cards (for example, when the parameter value is low), a character card with a high degree of rarity appears as a candidate character card. A candidate character card is selected from the second character card group having a high probability or a high number of rare character cards. Alternatively, if the types (attributes) of the ten character cards drawn in the first lottery process are biased, the probability that the type of character card is selected as a candidate character card increases or decreases. To do. Alternatively, a second character card group with many types of character cards is used, or conversely, a second character card group with few types of character cards is used. By doing so, the result of the first lottery process is reflected in the candidate character card selected in the second lottery process, and the user can select the candidate character card selected in this way. The desired character card can be designated from

  Moreover, in this embodiment, according to the status of the user's owned character card and the history information about the user's owned character card, the lottery probability in the second lottery process or k characters from the second character card group It is possible to change the setting of the second character card group when lottery candidate character cards are drawn.

  For example, in F1 of FIG. 11, the status of the user's owned character card and the history information about the owned character card are monitored. The history information is history information related to an operation such as editing (in / out operation) of the owned character card, for example, as will be described later with reference to FIG. Note that the situation of the owned character card may be a situation after 10 character cards are acquired, or may be a situation before 10 character cards are acquired.

  In this case, the second lottery that draws five (k) candidate character cards as shown in F2 according to the status of the user's owned character card shown in F1 and the history information about the owned character card. Change the lottery probability in the process. Or as shown to F3, the setting of the 2nd character card group at the time of drawing lots of 5 candidate character cards is changed.

  For example, the situation of the owned character card shown in F1 or the situation determined from the history information about the owned character card is not a character card with a high degree of rarity or a character card with a high parameter value. Suppose you have a lot of cards. In this case, in the second lottery process indicated by F2, for example, the lottery probability that a rare character card or a character card having a high parameter value is won is increased. Alternatively, as the setting of the second character card group shown in F3, a character card group having a high appearance probability or a large number of character cards having a high character value or a rare character card is used.

  On the other hand, it is assumed that the situation of the owned character card indicated by F1 and the situation determined from the history information about the owned character card are such that there are many character cards with a high degree of rarity and character cards with a high parameter value. In this case, in the second lottery process shown in F2, for example, the lottery probability that a rare character card or a character card having a high parameter value is hit is lowered. Alternatively, in the setting of the second character card group shown in F3, a character card group in which the appearance probability of a rare character card or a character card having a high parameter value is low or the number is small is used.

  Further, it is assumed that the situation of the owned character card shown in F1 and the situation determined from the history information about the owned character card are such that there are few specific series of character cards (specific type of character cards). In this case, in the second lottery process shown in F2, the probability that the character card of the specific series will win is increased. Alternatively, in the setting of the second character card group shown in F3, a character card group with a high appearance probability or a large number of character cards of the specific series is used.

  On the other hand, it is assumed that the situation of the owned character card shown in F1 and the situation determined from the history information about the owned character card are such that there are many specific series of character cards. In this case, in the second lottery process indicated by F2, the probability that the particular series of character cards will win is reduced. Alternatively, in the setting of the second character card group shown in F3, a character card group having a low appearance probability or a small number of character cards of the specific series is used.

  FIG. 12 is a diagram for explaining an example of history information about the owned character card. For example, the user may perform various operations (editing) on the possessed character card, and FIG. 12 is an example of history information of the operations. For example, the user deletes the owned character card, or uses the owned character card as a material for composition processing with other types (attributes) of character cards. For example, in the history information of FIG. 12, the user has deleted many of the possessed character cards of type GB. Also, the possessed character card of type GB is used as a material for composition processing with other types of character cards. Therefore, it can be determined from the history information in FIG. 12 that the type GB character card is not a user's collection target. Conversely, for example, when there are many type GA character cards generated by the synthesis process, it can be determined that the type GA character card is a collection target of the user.

  Therefore, if history information (operation history information) about such owned character cards is used, the types of character cards unnecessary for the user, what types of character cards the user likes and collects, etc. I can judge. Therefore, according to the situation determined from the history information about such possessed character cards, as shown in F2 and F3 of FIG. 11, the setting of the lottery probability for the candidate character cards and the second character card group Settings can be made.

  In the present embodiment, the number k of candidate character cards or the number n of character cards acquired in the second lottery process is changed according to at least one of the number of executions and the execution interval of continuous acquisition of m character cards. You may let them.

  For example, in G1 of FIG. 13, the number of executions and the execution interval of continuous acquisition of 11 (m) character cards (hereinafter, appropriately described as 11 continuous acquisitions) are monitored. For example, the number of executions of 11 consecutive acquisitions within a predetermined period (for example, 1 hour or 1 day) and the length of the execution interval are monitored. Based on the number of executions and the execution interval, the number k of candidate character cards is changed as indicated by G2. Alternatively, based on the number of executions and the execution interval, the number n of acquired character cards in the second lottery process is changed as indicated by G3.

  For example, it is assumed that eleven consecutive acquisitions are continuously performed five times during a predetermined period. In other words, it is assumed that the number of implementations within a predetermined period is 5 or more. Alternatively, it is assumed that 11 consecutive acquisitions are performed continuously 5 times at a short execution interval of a given length or less. In other words, it is assumed that the execution interval is less than a given length. In this case, in the normal state, the user can select n = 1 character card from k = 5 candidate character cards. When the 11th consecutive acquisition is performed for the fifth time, k = 15 The user can select n = 3 character cards from the candidate character cards. That is, the number k of candidate character cards and the number n of character card acquisitions in the second lottery process are changed as compared with the normal time (default time). This makes it possible to incorporate elements such as a step-up gasha into the 11-sheet continuous acquisition gasha (select gasha).

  For example, when the execution interval is short, such as performing 11 consecutive acquisitions many times within a predetermined period, or performing 11 consecutive acquisitions repeatedly in a short time, the A privilege is given to it. In other words, a user who has performed a large number of 11 consecutive acquisitions or has a short execution interval can specify the last character card from a larger number k (for example, 15) of candidate characters. Further, a user who has performed a large number of 11 consecutive acquisitions or has a short execution interval can specify a larger number n (for example, 3) of character cards as the last character card. Thereby, it becomes possible to give a user the effective motivation to carry out 11 consecutive acquisition, and it becomes possible to further improve the user's immersiveness degree and enthusiasm for the lottery play.

3. Detailed Processing Next, a detailed processing example of this embodiment will be described with reference to the flowchart of FIG.

  First, it is determined whether a continuous acquisition request (continuous gasha) for m character cards has been made (step S11). For example, it is determined whether or not the user of the terminal device has performed an operation to instruct execution of continuous acquisition of m character cards. And when there exists such a continuous acquisition request, the process which draws out (mn) character cards from the 1st character card group is performed (step S12). That is, as shown in B1 and B2 of FIG. 6, (mn) character cards are selected by lottery from the first character card group.

  Next, the second character card group and the lottery probability of candidate character cards are set (step S13). For example, as shown by E1, E2, and E3 in FIG. 10, according to the lottery result in the first lottery process, the lottery probability of the candidate character card and the second character card group are set. Alternatively, as shown in F1, F2, and F3 in FIG. 11, depending on the situation of the owned character card and the situation determined from the history information about the owned character card, Set the character card group. And the process which draws k candidate character cards out of the 2nd character card group is performed (step S14). That is, as shown in B3 and B4 of FIG. 6, k character cards are selected by lottery from the second character card group.

  Next, designation by the user is accepted (step S15). That is, as shown by A3 in FIG. 5, a user request for designating n character cards from the k candidate character cards is accepted. Then, the (mn) character cards selected in lots and the n character cards designated by the user from the k candidate character cards are registered as the user-owned character cards (step S16). That is, as indicated by A5 in FIG. 5, a total of m (n−n) character cards acquired in the first lottery process and n character cards acquired in the second lottery process. One character card is registered as a user-owned character card.

  Although the present embodiment has been described in detail as described above, it will be easily understood by those skilled in the art that many modifications can be made without departing from the novel matters and effects of the present invention. Accordingly, all such modifications are intended to be included in the scope of the present invention. For example, in the specification or drawings, terms (character cards, candidate character cards, character card groups, etc.) described at least once together with different terms (game media, candidate game media, game media groups, etc.) having a broader meaning or the same meaning are The different terms can be used anywhere in the specification or drawings. Further, the reception process, the lottery process, the registration process, the setting process, the game process, and the like are not limited to those described in this embodiment, and techniques equivalent to these are also included in the scope of the present invention.
