Abstract

To provide a new mechanism to alleviate discontent of a player with the duplication of imparted objects in object imparting processing for imparting a game object selected by random selection calculation like gacha to a player.SOLUTION: When an item (imparted item) imparted to a player 3 by executing gacha and an acquired item by past execution of gacha by the player 3 satisfy a correspondence condition (e.g., the same kind of items), a privilege associated with an imparted object is imparted to the player 3. As a first privilege, one privilege is imparted to the player 3, which is selected according to the kind, the number, a possession time, etc. of the acquired item that satisfies the correspondence condition out of a plurality of privileges associated with the imparted item. As for a second privilege, it is determined whether or not the second privilege is to be imparted to the player 3 according to an imparting probability set according to the kind, the number, rarity, a possession time, etc. of the acquired item that satisfies the correspondence condition.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a program and the like for causing a computer system to perform a giving process of giving a player a game object selected by performing a predetermined random selection operation.

  In many games, a system is installed in which a game object such as a character or an item that can be used in the game is selected by random selection calculation and given to a player. A typical example is gacha. In the gacha, since a given object is selected by a random selection operation, a game object already acquired by a player may be given.

  In order to alleviate the player's dissatisfaction with such overlapping of the assigned objects, for example, as disclosed in Patent Documents 1 and 2, the selection probability of an unacquired game object is increased, and the selection probability of an acquired game object is increased. For example, there is known a technique in which an unacquired game object is relatively easily provided by adjusting a selection probability such as lowering a game object.

[Overview]
In the game of the present embodiment executed using the player terminal 1500, the player 3 can execute a gacha at an arbitrary timing. The gacha is an example of an object providing process for providing a player with a game object selected by performing a random selection operation.

  As a method of selecting game objects, a method is selected by probability calculation according to a selection probability set for each game object, but the type and total number of game objects in a box which is a population are announced, When one is selected, the contents of the box are reduced by one, so that a so-called box gacha method may be used. The game object given by the gacha is an item that can be equipped or used by a character, but may be a character.

  FIG. 2 is a diagram illustrating an outline of a gacha in the present embodiment. In the gacha, a plurality of items that can be given as prizes are prepared, and one item is selected by a probability calculation according to a selection probability determined for each of the items, and is given to the player 3 as a prize. The selection probability determined for each item is determined, for example, in accordance with the degree of rarity. The higher the degree of rarity, the lower (lower) the selection probability.

  When the player 3 repeatedly performs the gacha, the same item may be given a plurality of times. As a feature of the present embodiment, an item given to the player 3 by performing the gacha (hereinafter, this item is appropriately referred to as an “added item”) corresponds to a predetermined correspondence between the item acquired by the player 3 performing the past gacha. If the condition is satisfied, a certain privilege is given to the player 3. Specifically, in the present embodiment, the corresponding condition is that the items are of the same type. In other words, a case where the acquired item of the player 3 includes an item of the same type as the granted item is a case where the corresponding condition is satisfied. Then, if the corresponding condition is satisfied, a privilege selected from the privileges predetermined as a privilege list is given to the player 3.

  The privilege is prepared in association with the grant item, and has contents related to the grant item. In the present embodiment, the privilege is an item, but may be a character, or may be an intangible object such as skill or magic. For example, an item that has an effect of improving the ability of the item by using the item to be provided or an item such as an accessory of the provided item can be set as a privilege.

  Also, two types of benefits, a first benefit and a second benefit, are prepared. As the first privilege, a plurality of types of benefits are prepared in association with one given item. One of a plurality of benefits associated with the granted item as the first benefit is selected according to the type and number of acquired items that satisfy the corresponding condition, the possession time, and the like. Granted.

  As the second privilege, one privilege is associated with one grant item and prepared. The grant probability is set according to the type and number of acquired items that satisfy the corresponding condition, the degree of rarity, the possession time, and the like, and it is determined whether or not to grant the second privilege according to the set grant probability, and it is determined to grant. In this case, the determined second privilege is given to the player 3. When it is determined not to give in accordance with the giving probability, the second privilege is not given to the player 3.

Setting data. As shown in FIG. 7, display body data and parameter initial values are stored in association with each other for each type of item. The parameter initial value is the rarity, attribute, and level of the item of the type, the action or utility that occurs on the character by using the item (for example, if the weapon is a weapon, the attack power increases by equipping, or the recovery item) (Such as the physical strength value that increases with use).

  When an item is assigned to the player 3, a new item having a parameter initial value defined by the corresponding type of item initial setting data 316 is generated, and a unique item ID is assigned and assigned. .

  The gacha management unit 220 includes a provided item selection unit 222, a corresponding condition determination unit 224, a benefit determination unit 226, and a benefit provision control unit 228, and manages the execution of a gacha in a game. In the game of the present embodiment, a plurality of types of gacha can be provided. Specifically, for each character that can be selected as a player character, a gacha having the character as a related subject is prepared. In each gacha, items related to the character of the related subject are prepared as prizes. The related item is an item that can be equipped or used by the related subject character. Of course, it is possible to provide a gacha that is not related to a specific character. However, in the present embodiment, for the sake of simplicity of description, it is assumed that a related subject character is determined for each gacha. In the case of making the gacha irrelevant to a specific character, a plurality of (for example, all) characters may be set in association with the related subject character.

  The content of the provided gacha is determined by the gacha setting data 330. FIG. 8 shows an example of the gacha setting data 330. According to FIG. 8, the gacha setting data 330 is generated for each gacha, and stores a unique gacha ID 331, gacha type 332, provision period 333, and grant item list 334 in association with each other. The gacha type 332 is the type of the target character. The given item list 334 stores the types of items that can be given as prizes for gacha and the selection probabilities in association with each other. The total of the selection probabilities is 100%, and one type of gacha is provided with any type of item.

  The given item selection unit 222 selects an item (given item) to be given to the player 3 by performing the gacha. Specifically, referring to the provided item list 334 of the corresponding gacha setting data 330, a probability calculation is performed according to a selection probability determined for each item type, and one item to be provided as a premium is selected.

  The corresponding condition determining unit 224 determines whether or not the provided item to be provided to the player 3 and the acquired item that has been acquired by the player 3 satisfy a predetermined corresponding condition. Specifically, it is determined whether or not the item (granted item) selected by the grant item selection unit 222 is included in the acquired items of the player 3 on the condition that the items are of the same type. The acquired item is an item acquired by performing the past gacha with reference to the item possession history data 329 of the corresponding player management data 320. It should be noted that the word “acquired” means that it has only been acquired, irrespective of whether or not it is owned at the present time.

  The privilege determining unit 226 determines a privilege to be provided to the player 3 based on the acquired item that satisfies the corresponding condition when the corresponding condition determining unit 224 determines that the corresponding condition is satisfied.

  The contents of the privilege that can be given are defined in the privilege setting data 340. FIG. 9 is a diagram illustrating an example of the privilege setting data 340. According to FIG. 9, the privilege setting data 340 stores a first privilege and a second privilege in association with each other for each item that can be given in a gacha. A plurality of benefits are associated with each other by privilege rank as the first privilege, and one privilege is associated with the second privilege. In the example of FIG. 9, the higher the rarity item, the higher the ratio of the item with the higher rarity in the first privilege, and the higher the rarity in the second privilege. In addition, the first privilege associated with the same granted item is associated with an item having a higher degree of rarity as the privilege rank is higher.

  The privilege determining unit 226 refers to the privilege setting data 340 to determine a plurality of privileges associated with the granted item as the first privilege, and refers to the privilege grant condition table 350 from among the plurality of benefits. Then, the privilege corresponding to the privilege rank corresponding to the acquired item satisfying the corresponding condition is determined as the first privilege to be provided to the player 3.

  FIG. 10 is a diagram illustrating an example of the privilege provision condition table 350. The privilege provision condition table 350 includes two types of data tables 350a and 350b in which condition items related to acquired items are different. Use one of the data tables depending on the situation. For example, one may be selected and used at random, or a data table to be used for each type of gacha is defined and stored in the gacha setting data 330, and is associated with the gacha instructed by the player. Alternatively, the data table that is used may be used. Alternatively, the usage probability of each of the two types of data tables is determined for each type of gacha and stored in the gacha setting data 330, and the data table used in accordance with the usage probability associated with the gacha instructed by the player May be selected. Alternatively, the privilege rank may be determined using each of the two types of data tables, and the privilege corresponding to the higher privilege rank among the determined privilege ranks may be given as the first privilege.

  FIG. 10A is a privilege grant condition table 350a for determining a privilege based on the type and number (duplicate number) of acquired objects that satisfy the corresponding condition. Specifically, since the type of acquired items that satisfy the corresponding condition is the same as the granted item, the number (duplicate number) of acquired items is set as a condition item, and the duplicate number and the privilege rank are set in association with each other. It is determined that the greater the number of duplicates, the higher the privilege rank of the privilege to be granted.

  When the privilege condition table 350a is used, the privilege determining unit 226 determines the number (duplicate number) of acquired items determined to satisfy the corresponding condition by the corresponding condition determining unit 224. The privilege rank associated with the duplication number is determined. Then, in the privilege setting data 340, a privilege corresponding to the determined privilege rank among a plurality of privileges associated with the grant item selected by the grant item selecting unit 222 as the first privilege is determined as the first privilege. I do. For example, if the granted item is “item β” and the number (duplicate number) of acquired items that satisfy the corresponding condition is “12”, the privilege rank corresponding to this is “rank D”, and therefore “item b4”. "Is the first privilege.

  FIG. 10B is a privilege grant condition table 350b for determining a privilege based on the time (owning time) when the player has owned a plurality of acquired items satisfying the corresponding condition. Specifically, the number of duplicate possessions and the possession time are used as condition items, and the privilege rank of the privilege to be granted is set in association with each combination of the number of duplicate possessions and the longest possession time. The number of duplicate possessions is the number of possessions of acquired items that satisfy the corresponding condition. The player 3 can own the item acquired by performing the gacha as it is, or can use it for composition at any time, throw it away, or transfer it to another player. Increases or decreases over time. For this reason, the time during which the state in which the number of owned items is the same for a certain type of item is continued is defined as the owned time of the owned number, and the maximum time is the maximum owned time of the owned number.

  When using the privilege provision condition table 350b, the privilege determination unit 226 refers to the item possession history data 329 of the corresponding player management data 320, and determines the possession period of each acquired item satisfying the corresponding condition. In other words, for items that are currently owned, the period from the acquisition date to the current date is the ownership period, and for items that are not owned (lost), the period from the acquisition date to the loss date is the ownership period. . Next, from the distribution of the ownership period for each item, a time-series change in the number of owned items (number of duplicate possessions) in the period from the player registration time to the current time is obtained, and further, the maximum ownership time for each number of duplicate possessions is determined. . Subsequently, in the privilege provision condition table 350b, the privilege rank corresponding to each combination of the number of duplicate possessions and the longest possession time is extracted, and the highest (best for the player) privilege rank is determined from these. Then, in the privilege setting data 340, a privilege corresponding to the determined privilege rank among a plurality of privileges associated with the grant item selected by the grant item selecting unit 222 as the first privilege is determined as the first privilege. I do.

  For example, the granted item is “item β”, the time of possession of “one” acquired items satisfying the corresponding condition is “8 days”, and the time of possession of “two” is “5 days”. It is assumed that the time when "6" are owned is "3 days" and the time when "25" is owned is "10 hours". The privilege rank corresponding to each combination of the number of duplicate possessions and the minimum possession time defined in the privilege grant condition table 350b is “rank D”, “rank E”, “rank D”, and “rank C”. Therefore, the highest privilege rank is “rank C”. In the privilege setting data 340, among the privileges associated with “item β” as the first privilege, “item b3” of “rank C” is the first privilege.

  In addition, the privilege determining unit 226 refers to the privilege setting data 340 and determines the second privilege associated with the provided item. In addition, the provision probability is set based on the acquired items that satisfy the corresponding condition. That is, the provision probability is set by referring to the privilege provision probability table 360, and then the provision probability is changed by referring to the provision probability change table 370. Then, it is determined whether or not to grant the second privilege to the player 3 by a probability calculation according to the set / changed grant probability. If it is determined that the second privilege is to be provided, it is determined that the determined second privilege is provided to the player 3.

  FIG. 11 is a diagram illustrating an example of the privilege provision probability table 360. The privilege provision probability table 360 is a data table for determining a provision probability based on the number and types of acquired items that satisfy the corresponding condition. Since the type of the acquired item that satisfies the corresponding condition is the same as that of the grant item, as shown in FIG. 11, the privilege grant probability table 360 includes the number of acquired items that satisfy the corresponding condition, Are stored in association with each other. It is set so that the provision probability increases as the number of duplicates increases.

  FIG. 12 is a diagram illustrating an example of the assignment probability change table 370. The assignment probability change table 370 includes two types of data tables in which condition items related to acquired items are different. Use one of the data tables depending on the situation. For example, one of them may be selected and used at random, or a data table to be used for each type of gacha may be determined and stored in the gacha setting data 330 to be associated with the performed gacha. May be used. Alternatively, the use probability of each of the two types of data tables is determined and stored in the gacha setting data 330 for each type of gacha, and the data table to be used is selected according to the use probability associated with the implemented gacha. You may do it. Alternatively, the privilege rank may be determined using each of the two types of data tables, and the privilege corresponding to the higher privilege rank among the determined privilege ranks may be given as the first privilege.

  FIG. 12A is an assignment probability change table 370a for changing the assignment probability based on the time (owning time) in which the player has owned a plurality of acquired objects satisfying the correspondence condition. For each combination with the longest possession time, the amount of change in the application probability is stored in association with it. In the example of FIG. 12A, it is determined that the larger the number of duplicate possessions or the longer the longest possession time, the larger the amount of change in the grant probability.

  When using the grant probability change table 370a, the privilege determining unit 226 determines the number (duplicate number) of acquired items determined to satisfy the corresponding condition by the corresponding condition determining unit 224. Then, the assignment probability associated with the duplication number is determined. Next, similarly to the case of using the above-described privilege granting condition table 350b (see FIG. 10B), referring to the item possession history data 329 of the corresponding player management data 320, the acquired item satisfying the corresponding condition is determined. And the maximum ownership time for each duplicate ownership number. Subsequently, in the assignment probability change table 370a, the assignment probability change amount corresponding to each combination of the number of duplicate possessions and the longest possession time is extracted, and the maximum assignment probability change amount is determined from these. Then, the determined application probability is changed by the application probability change amount,

  For example, if the granted item is “item β” and the number (duplicate number) of acquired items that satisfy the corresponding condition is “12”, the grant probability determined in the privilege grant probability table 360 is “3.0 [%]. ". In addition, the time when “one” of the acquired items is owned is “8 days”, the time when “2” is owned is “5 days”, and the time when “16” are owned It is assumed that “3 days” and “35 hours” are “10 hours”. The assignment probability change amounts corresponding to each combination of the number of duplicate possessions and the longest possession time determined in the assignment probability change table 370a are “+0.1 [%]”, “− (none)”, “+0. 3 [%] "and" +0.5 [%] ", the largest change in the application probability is" +0.5 [%] ". Therefore, the final provision probability of the second privilege is “3.5 [%]”.

  FIG. 12B is an assignment probability change table 370b for changing the assignment probability based on the rarity of the acquired object that satisfies the correspondence condition, and stores the rarity and the change amount of the assignment probability in association with each other. ing. In the example of FIG. 12B, the higher the degree of rarity, the higher the change amount of the application probability is set.

  When using the grant probability change table 370b, the privilege determining unit 226 determines the number (duplicate number) of acquired items determined to satisfy the corresponding condition by the corresponding condition determining unit 224. Then, the assignment probability associated with the duplication number is determined. Next, in the assignment probability change table 370b, the assignment probability change amount associated with the rarity of the acquired object that satisfies the corresponding condition is determined, and the determined assignment probability is changed by this assignment probability change amount.

  For example, if the granted item is “item β” and the number (duplicate number) of acquired items that satisfy the corresponding condition is “12”, the grant probability determined in the privilege grant probability table 360 is “3.0 [%]. ". In addition, since the rarity of “item β” is “rare (= R)”, the change amount of the provision probability determined in the provision probability change table 370b is “+0.3 [%]”. Therefore, the final second privilege award probability is “3.3 [%]”.

  The privilege granting control unit 228 performs control for granting the privilege determined by the privilege determining unit 226 to the player 3 when the corresponding condition determining unit 224 determines that the corresponding condition is “satisfied”. In other words, a unique item ID is assigned to the item that is the first privilege and the second privilege, and the item ID is added to the item owned by the corresponding player 3.

[Process flow]
FIG. 14 is a flowchart illustrating the flow of a process related to the implementation of gacha. This processing is executed by the gacha management unit 220 while communicating with the player terminal 1500 of the target player.

  The gacha management unit 220 first selects a gacha type to be executed from a plurality of types of gachas prepared according to an instruction of the target player (step S1). The gacha is performed with reference to the player management data 320 of the target player, the gacha setting data 330 corresponding to the type of the selected gacha, and the like. That is, the given item selection unit 222 refers to the given item list 334 of the corresponding gacha setting data 330, and determines an item (granted item) to be given as a prize according to the selection probability determined for each item (step S3). . Next, the corresponding condition determining unit 224 refers to the item possession history data 329 of the corresponding player management data 320 to determine whether the determined added item and the acquired item of the target player satisfy the corresponding condition ( Step S5). If the corresponding condition is not satisfied (step S7: NO), the privilege provision control unit 228 provides the provision item to the target player (step S21).

  If the corresponding condition is satisfied (step S7: YES), the privilege determining unit 226 determines the first privilege based on the acquired items that satisfy the corresponding condition (step S9). That is, with reference to the privilege grant condition table 350, the privilege rank of the privilege to be granted as the first privilege is determined based on the type and number of acquired items that satisfy the corresponding condition, the required time, and the like. In the present embodiment, two types of privilege provision condition tables 350a and 350b are prepared as the privilege provision condition table 350 (see FIG. 10), and among these, for example, according to the type of gacha to be performed, or A data table to be used is selected by random calculation. If the privilege grant condition table 350a is used, the number (duplicate number) of acquired items that satisfy the corresponding condition is determined by referring to the item possession history data 329 of the corresponding player management data 320, and the determined duplicate number is determined. Determine the corresponding privilege rank. If the privilege grant condition table 350b is used, the longest possession time is obtained for each duplicate possession number for the acquired items satisfying the corresponding condition by referring to the item possession history data 329 of the corresponding player management data 320, and The highest privilege rank among the privilege ranks corresponding to each combination of the number of possessions and the longest possession time is determined. Then, by referring to the privilege setting data 340, a privilege associated with the first privilege with the provided item is determined, and among these benefits, the privilege of the determined privilege rank is determined as the first privilege.

  In addition, the privilege determining unit 226 sets the probability of providing the second privilege based on the acquired items that satisfy the corresponding condition (step S11). That is, the second privilege associated with the granted item is determined with reference to the privilege setting data 340. Further, referring to the privilege provision probability table 360, the provision probability is set based on the number (duplicate number) of acquired items that satisfy the corresponding condition. Next, referring to the grant probability change table 370, the grant probability is changed based on the possession time and the rarity of the acquired item satisfying the corresponding condition. In the present embodiment, two types of application probability change tables 370a and 370b are prepared as the application probability change table 370 (see FIG. 12), and among these, for example, according to the type of gacha to be performed, or A data table to be used is selected by random calculation. If the application probability change table 370a is used, the longest possession time is obtained for each duplicate possession number for the acquired items satisfying the corresponding condition by referring to the item possession history data 329 of the corresponding player management data 320, Among the assignment probability change amounts corresponding to the respective combinations of and the longest possession time, the largest assignment probability change amount is determined. Then, the set application probability is changed by the application probability change amount. If the provision probability change table 370b is used, the provision probability change amount corresponding to the rarity of the acquired item satisfying the corresponding condition is determined. Then, the set application probability is changed by the application probability change amount. Thereafter, it is determined whether or not to grant the second privilege according to the set grant probability (step S13).

  If it is determined to give (Step S15: YES), the privilege giving control unit 228 gives the given item to the target player together with the first benefit and the second benefit (Step S17). On the other hand, if it is determined not to grant the second privilege (step S15: NO), the privilege granting control unit 228 grants the grant item to the target player together with the first privilege (step S19). When the above processing is performed, this processing ends.

[Effects]
As described above, according to the present embodiment, when the provided item by performing the gacha and the acquired item of the player 3 satisfy the corresponding condition, the benefit based on the acquired item that satisfies the corresponding condition is further provided to the player. You. If the items of the same type are set as the corresponding condition, the privilege is given when the provided items overlap, so that an effect of relieving the player 3 of dissatisfaction with the provided item overlap can be obtained.

[Modification]
It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

(A) Corresponding Condition In the above embodiment, the corresponding condition between the granted item and the acquired item is the same type of item, but is not limited to this. For example, different types of correspondences in which the type of the granted item and the type of the acquired item are associated in advance in one-to-one, one-to-many, many-to-one, or many-to-many may be used. For example, with respect to the given item “just sword”, the acquired item to be in a correspondence relationship may be “just sword” on a one-to-one basis, or all items related to “sword” may be one-to-many. When there are a plurality of granted items, the opposite correspondence can be established.

  Further, the fact that the attributes are the same (the same attribute condition) may be included in the corresponding condition. More specifically, in the above-described embodiment, the corresponding condition is that the types are the same, but instead, the attribute is the same (the same attribute condition) is set as the corresponding condition. In this case, the privilege setting data 340A shown in FIG. 15 is used instead of the privilege setting data 340 (see FIG. 9). The privilege setting data 340A is a data table in which the item of “granted item” in the privilege setting data 340 is replaced with “attribute of the granted item”, and the privilege is defined in association with each attribute. Then, a benefit associated with the attribute that satisfies the attribute condition, which is the corresponding condition, is provided to the player.

  Alternatively, the fact that the attribute is the same (the same attribute condition) may be added to the corresponding condition, and the corresponding condition may be configured by a plurality of conditions including the same attribute condition. In this case, an AND determination that the corresponding condition is satisfied when all the conditions constituting the corresponding condition are satisfied, or an OR determination that the corresponding condition is satisfied when at least one of the corresponding conditions is satisfied is satisfied. It is good.

(B) N consecutive gachas The present embodiment is also applicable to a so-called N consecutive gacha (also referred to as a continuous gacha) in which a plurality of (N: N ≧ 2) items are collectively provided in one execution. . In the N consecutive gacha, a random selection operation according to a selection probability determined for each item is continuously performed N times, and one grant item is selected each time, so that a total of N grant items are selected. You.

  In this case, it is determined whether or not each of the plurality (N) of the provided items provided by performing the N consecutive gacha satisfies the acquired items of the player and the corresponding conditions. If there is only one grant item that satisfies the corresponding condition, a benefit based on the acquired item corresponding to the grant item is given to the player 3. When there are a plurality of granted items satisfying the corresponding condition, all the benefits among the benefits based on the acquired items corresponding to the respective granted items satisfying the corresponding condition may be provided. A privilege may be selected and provided. The privilege that is “advantageous” to the player 3 corresponds to, for example, a high degree of rareness, that the player has not been acquired, and the like.

  Alternatively, it may be determined whether or not a plurality of (N) added items satisfy the corresponding condition. That is, the combination (group) of the provided items that satisfy the corresponding condition included in the plurality of provided items is determined, and the privilege is determined based on the provided objects constituting the determined combination (group). Just do it.

  For example, as in the above-described embodiment, if the corresponding condition is that the items are of the same type, combinations (groups) of the same type of provided items satisfying the corresponding condition among a plurality (N) of provided items. It becomes. For example, among the items that became the granted items when 100 consecutive gachas (N = 100) were performed, 70 (M = 90) items became a first group of the same type, and a different type from the first group In this case, 20 (M = 20) items form a second group of the same type. As described above, as the number (N) of the granted items given by one execution of the N consecutive gacha is larger, a combination (group) of M (N ≧ M) given objects that satisfies the corresponding condition is more easily created. Moreover, the number of M in one group tends to increase. Therefore, one group that satisfies such a condition that the number of granted items satisfying the corresponding condition (M: overlapping number) is the largest, or the group of granted items that satisfy the corresponding condition is the highest rarity A bonus is granted based on the selected items that make up the selected group. Specifically, the privilege set in the privilege setting data 340 (see FIG. 9) is provided in association with the provided items constituting the selected combination (group). Which privilege is granted as the first privilege and whether or not to grant the second privilege are determined by referring to the “acquired items satisfying the corresponding condition” in the above-described embodiment as “the grant constituting the combination (group). This can be realized in the same way by reading "item".

(C)
Further, in the case of a game played by a team composed of a plurality of players, in addition to the acquired items of the player 3 who has performed the gacha, the acquired items of the other players of the team to which the player 3 belongs are acquired. The privilege to be granted may be determined based on the item. Specifically, it is determined whether or not the item to be provided to the player 3, the obtained item of the player 3, and each of the other players of the team to which the player 3 belongs, or the corresponding condition is satisfied, and the obtained condition that satisfies the corresponding condition is obtained. Based on the item, a privilege given to the player 3 is determined.

  Alternatively, the number of other players for which the acquired item satisfies the corresponding condition (hereinafter, referred to as “overlapping number”) or the ratio of the number of players to the total number of players of the team (hereinafter, referred to as “overlapping ratio”). The privilege may be determined accordingly. That is, as the privilege granting condition table 350, a data table in which the number of overlapping persons and the overlapping ratio are associated with the privilege rank is prepared in advance, and the privilege rank is determined in accordance with the data table. Determine benefits. Of course, the privilege rank is determined using both or one of the privilege provision condition tables 350a and 350b (see FIG. 10), and the privilege corresponding to the highest privilege rank among the determined privilege ranks is provided as the first privilege. You may do it.

  Similarly, for the second privilege, a data table is prepared in advance as the privilege grant probability table 360 in which the number of overlapping persons and the overlapping ratio are associated with the grant probability, and the grant probability is set in accordance with the data table. , Determine whether to grant the second privilege. Alternatively, as the assignment probability change table 370, a data table in which the number of overlapping persons or the overlap ratio is associated with the amount of change in the assignment probability may be prepared in advance, and the assignment probability may be changed according to the data table. Of course, both or one of the grant probability change tables 370a and 370b (see FIG. 12) are used to determine the grant probability change amount, and the grant probability is determined by the largest grant probability change amount among the determined grant probability change amounts. It may be changed.

  Further, in addition to the privilege given to the player 3, a privilege (hereinafter, referred to as “team privilege”) may be given to the team to which the player belongs or another player to which the player belongs. The team privilege may be the same privilege as the player 3 or a different privilege. In the case of different benefits, for example, in the benefit setting data 340 (see FIG. 9), a team benefit may be further associated with each granted item.

(D) Another Example of Assigning Process In the above-described embodiment, the gacha, which is an example of the object assigning process, has been described. However, the present invention is similarly applicable to other assigning processes. For example, in the case of a battle game in which the game is played against another player or an enemy character, a process of giving a victory reward after the battle, a process of dropping after defeating the enemy character, and a process of giving a reward for participating in a predetermined event The present invention can be applied to any process that determines an application object according to a selection probability determined for each game object, such as a process of applying a clear bonus for a specific stage.

(E) Computer System In the above embodiment, the server system 1000 has been described as an example of a computer system. However, the player terminal 1500 may be a computer system.
