[0004] [Patent Document 1] Patent No. 3222869 Summary of the Invention [Problem to be solved by the invention]

[0005] In such games, the probability of winning the content to be selected in the lottery game is often presented to the player. However, this probability is a theoretical probability, and there may be an error between the probability and the actual ratio of the content provided to the player. This may cause players to distrust the lottery game.

[0006] The present invention has been made in consideration of such problems, and its object is to provide a program and an information processing device that can provide a lottery game that does not cause players to feel distrustful. [Means for solving the problem]

[0007] In order to solve the above problem, a program according to a first aspect of the present invention causes a computer to function as: a lottery means for executing a lottery game which, upon request from a player, provides the player with content selected based on the selection probability for each piece of content to be selected; a management means for managing the total number of times the lottery game has been executed by a plurality of players and the total number of times a specific content has been provided in the lottery game; and a presentation means for presenting to the plurality of players information indicating the provision ratio of the specific content according to the total number of times it has been executed and the total number of times it has been provided.

[0008] In addition, in a second aspect of the present invention, the lottery means executes the lottery game by consuming items owned by the player, and causes the computer to function as a return means that returns a part or all of the consumed items to the player who executed the lottery game when a predetermined time arrives and the provision rate of the specific content is lower than a predetermined probability corresponding to the lottery probability of the specific content.

[0009] In a third aspect of the present invention, the return means returns a greater number of items as the provision rate of the specific content becomes lower than the predetermined probability.

[0010] In a fourth aspect of the present invention, the return means returns an item to a player who has played the lottery game a predetermined number of times or more and has not been provided with the specific content.

[0011] In addition, in a fifth aspect of the present invention, the return means returns a greater number of items to a player who has been provided with less than a predetermined number of specific characters than to a player who has been provided with a predetermined number or more of the specific content through the execution of the lottery game.

[0012] In a sixth aspect of the present invention, the items include paid items that the player can acquire through a purchase procedure and free items that the player can acquire through game play, and the return means returns the free items to the player who played the lottery game.

[0013] In a seventh aspect of the present invention, the lottery means executes the lottery game by consuming only paid items owned by the player.

[0014] In an eighth aspect of the present invention, the lottery means executes the lottery game by preferentially consuming paid items over free items owned by the player.

[0015] In a ninth aspect of the present invention, the return means returns a greater number of free items as the number of consumed paid items increases.

[0016] In a tenth aspect of the present invention, the specific content is content having a rarity equal to or greater than a predetermined value.

[0039] The speaker 42 has a function of outputting game sounds and the like.

[0040] <Game Overview> The game according to the present embodiment includes a lottery game in which a character is provided (acquired) to the player as an example of content, and a quest. The lottery game may be called gacha, lottery, summoning, etc. The quest may be called a battle game, dungeon, exploration, mission, etc.

[0041] In this embodiment, there are one or more types of lottery games, each of which has a different name (title). The lottery game can be selected by the player on a menu screen of the lottery game, etc. In this embodiment, when a player selects one of the one or more types of lottery games, a screen is displayed that allows the player to select a single lottery in which the one lottery game is executed once or a continuous lottery in which the one lottery game is executed ten times in a row. This single lottery may be called a single gacha, a one-time lottery, a one-time summon, etc. Furthermore, this continuous lottery may be called a 10-time gacha, a 10-time lottery, a 10-time summon, etc. Then, based on an instruction (request) to execute the single lottery or the continuous lottery from the player, a character randomly selected from a lottery target character group (lottery target content group) corresponding to the one lottery game is provided to the player. This lottery game is executed based on consuming a consideration. More consideration is consumed for the continuous lottery than for the single lottery. Examples of this compensation include paid items (charged items) and free items (non-charged items). A paid item is an item that a player can acquire by a purchase procedure (payment of cash or electronic money, credit card payment, etc.). Examples of paid items include paid stones, paid gacha tickets, paid coins, etc. A free item is an item that a player can acquire by playing a game (execution of various games). For example, a free item can be acquired as a reward for logging in, clearing a quest, completing a mission, interacting with friends, etc. Examples of free items include free stones, free gacha tickets, stamina recovery items, game coins, friend points, etc. In addition, the paid items and free items can be used not only for executing a lottery game, but also for various purposes such as stamina recovery and continuing a quest. In addition, paid items are more valuable than free items. For example, in a lottery game that can be executed by consuming only paid items, it is easier to acquire a character with a higher rarity (rare value) than in a lottery game that can be executed by consuming free items. In addition, paid stones and unpaid stones are sometimes referred to as "stones."

[0042] In this embodiment, there are one or more types of quests, each with a different name (title). The quests can be selected by the player on a quest menu screen or the like. In this embodiment, the player selects one of the one or more types of quests based on an operation instruction (request) to select the one quest. The quest is executed based on consuming a consumption stamina value associated with the quest from the player's current stamina value. If the stamina associated with the quest is greater than the stamina associated with the player, the player cannot execute (play) the quest. This stamina may also be referred to as life, action points (AP), battle points (BP), etc. The player's current stamina value may be consumed at the end of the quest (when cleared or retired).

[0043] In this embodiment, a quest is executed in which a team consisting of one or more characters (owned characters) owned by a player is pitted against an enemy character. In this quest, for example, the player instructs the characters (team characters) that make up the team to attack, etc. In this quest, the player aims to reduce the hit points of the enemy character to 0 or less using the ability parameters and skills of each of the team characters. When the quest is cleared, the player acquires a clear reward such as free stones, game coins, characters, items, experience points, etc. In addition, in a quest that the player has already cleared, the player may not acquire free stones. In addition, when the quest cannot be cleared, the player selects whether to continue the quest by consuming, for example, paid stones or free stones, a continue item, etc., or to retire from the quest. Continuing means giving a player who was unable to clear the quest a continuation right to continue playing the quest.

[0044] <Function means> FIG. 4 is a block diagram showing an example of a functional configuration of the server device 10. As shown in FIG.

[0045] 4, the server device 10 has, as functional components, a storage means 50, a lottery means 52, a management means 54, a presentation means 56, and a return means 58. The storage means 50 is realized by one or more storage devices 28. The functional means other than the storage means 50 are realized by the control device 20 executing the game program 14 stored in the storage device 28 or the like.

[0046] The storage means 50 is a functional means for storing player information 50A, character information 50B, lottery game information 50C, and the like.

[0047] The player information 50A is stored for each player in association with the player ID of the player. The player information 50A includes, for example, the player's name, age, owned character information, owned item information, lottery game execution information, and stamina information. The owned character information includes the character ID and ability parameters of each character owned by the player (owned character). The ability parameters are, for example, the character's level, hit points, attack power, defense power, etc. The character's level increases when the character acquires character experience points. When the character's level increases, the hit points, attack power, defense power, etc. also increase. The owned item information includes the number of each item owned by the player, such as paid stones, paid gacha tickets, free stones, free gacha tickets, etc. The lottery game execution information includes the number of times each lottery game has been executed by the player and the number of times a specific character has been provided in each lottery game. For example, the number of times executed is incremented by 1 when a lottery game in which one lottery (single lottery) is executed by the player. Also, the number of times executed is incremented by 10 when a lottery game in which ten lotteries (continuous lotteries) are executed by the player. Also, for example, the number of times provided is incremented by 1 when one specific character is provided to the player. The stamina information includes the player's current stamina value and stamina upper limit value. The current stamina value is the value consumed by the player when performing each type of quest. This current stamina value increases by a certain amount (e.g., 1) over the passage of time (e.g., 3 minutes), recovering to the stamina upper limit value. In addition, this current stamina value can be recovered beyond the stamina upper limit value by the player consuming paid stones, free stones, stamina recovery items, etc. This stamina upper limit value increases as the player's player rank increases. The player rank increases, for example, when the player acquires player experience points by playing the game (e.g., quests and missions).

[0048] Character information 50B is stored for each character in association with the character ID of the character. This character information 50B includes, for example, the character's name, image (design), rarity, initial values ​​of ability parameters (e.g., hit points, attack power, defense power, etc. at level 1) and maximum values ​​(e.g., hit points, attack power, defense power, etc. at level 100), skills, etc. The rarity includes a number ranging from 1 to 6. This number may be indicated by, for example, the number of stars. Characters with high rarity are set with ability parameters and skills that are advantageous in the game (for example, quests and missions).

[0049] The lottery game information 50C is stored for each lottery game in association with the lottery game ID of the lottery game. The lottery game information 50C includes, for example, the name (title), lottery target information, consecutive number, lottery consideration, total number of executions, and total number of offers. The lottery target information includes the character ID of each character constituting the lottery target character group that is the lottery target of the lottery game, and the appearance frequency (weight) associated with the character ID. The characters constituting the lottery target character group are, for example, 100 kinds. The appearance frequency includes, for example, a numerical value from 1 to 10. A low numerical value is set for the appearance frequency of a character with a high rarity, and a high numerical value is set for a character with a low rarity. In addition, a character (pickup character) that appears more frequently than other characters within the same rarity may be provided. Here, the lottery probability of one character (theoretical lottery probability) is a value obtained by dividing the appearance frequency set for the one character by the total value of the appearance frequencies set for each character that is the lottery target. Specifically, if the appearance frequency set for one character is 2 and the total value of the appearance frequencies set for each character that is the lottery target is 400, the lottery probability of the one character is 2 / 400 (0.5%). The consecutive number includes the number of consecutive lotteries to be performed when a consecutive lottery is instructed by the player. The consecutive number includes, for example, 10. The lottery consideration includes the number of items required to execute one lottery (single lottery) and the consumption method. For example, when a single lottery is instructed by the player, the same number of items as the lottery consideration (e.g., 5 items) are consumed. Also, when a continuous lottery is instructed by the player, the number of items consumed is the product of the lottery consideration (e.g., 5 items) and the number of continuous times (e.g., 10 times) (e.g., 50 items). Examples of the consumption method include consuming only paid items, consuming only free items, consuming paid items with priority, consuming free items with priority, consuming items in order of oldest acquisition date, consuming items in order of newest acquisition date, etc. Consuming paid items with priority means that when a player owns both paid items and free items, the paid items are consumed first. Similarly, consuming free items with priority means that when a player owns both paid items and free items, the free items are consumed first. The total number of executions includes the number of times (total number of times) a lottery game has been executed by multiple players. For example, the total number of executions is increased by 1 when a lottery game in which one lottery drawing (single lottery drawing) is executed by a first player. Also, the total number of executions is increased by 10 when a lottery game in which ten lotteries (continuous lotteries) are executed by a second player. The total number of times provided includes the number of times (total number of times) a specific character (specific content) has been provided as a result of a lottery game being played by multiple players. This specific character (specific content) is one or more characters (contents) specified by the game operator from a group of characters to be selected by lottery. An example of this specific character is a character whose rarity is a predetermined value (e.g., 5) or more. For example, when one specific character is provided to a first player, the total number of times provided increases by 1. Also, for example, when two specific characters are provided to a second player, the total number of times provided increases by 2.

[0050] The lottery means 52 is a functional means for executing a lottery game (single lottery game or continuous lottery game) based on a request (execution instruction) from a player. In this embodiment, the lottery means 52 executes a lottery game in which characters (contents) selected based on the probability of selection of each of a group of characters (group of contents) to be selected are provided to the player in response to a request from the player.

[0051] Also, the lottery means 52 executes the lottery game by consuming items owned by the player. For example, the lottery means 52 executes the lottery game by consuming only paid items owned by the player. Specifically, when the method of consuming the lottery consideration in the lottery game information 50C includes consuming only paid items, the lottery means 52 executes the lottery game in which only paid items are consumed. Also, for example, the lottery means 52 executes the lottery game by preferentially consuming paid items over free items owned by the player. Specifically, when the method of consuming the consumption consideration in the lottery game information 50C includes preferentially consuming paid items, the lottery means 52 executes the lottery game in which paid items are consumed before free items.

[0052] The management means 54 is a functional means for managing various information within the game. In this embodiment, the management means 54 manages the number of times a lottery game is executed by a plurality of players, the total number of times it is executed, and the number of times a specific character is provided in the lottery game, and the total number of times it is provided. Specifically, the management means 54 manages the number of times it is executed and the number of times it is provided in the lottery game in the player information 50A. The management means 54 also manages the total number of times it is executed and the total number of times it is provided in the lottery game information 50C. For example, when a first player draws one lottery game once (single draw), the management means 54 increases the number of times that one lottery game has been executed in the lottery game execution information of the first player and the total number of times that one lottery game has been executed in the lottery game information 50C by 1. Also, for example, when a second player draws one lottery game 10 times (consecutive draws), the management means 54 increases the number of times that one lottery game has been executed in the lottery game execution information of the second player and the total number of times that one lottery game has been executed in the lottery game information 50C by 10. Furthermore, for example, when the management means 54 provides one specific character to a first player in one lottery game, the management means 54 increases the number of times that one lottery game is provided in the lottery game execution information of the first player and the total number of times that one lottery game is provided in the lottery game information 50C by 1. Furthermore, for example, when the management means 54 provides two specific characters to a second player in one lottery game, the management means 54 increases the number of times that one lottery game is provided in the lottery game execution information of the second player and the total number of times that one lottery game is provided in the lottery game information 50C by 2.

[0053] Furthermore, the management means 54 calculates the provision ratio of a specific character (specific content) according to the total number of times the game is executed and the total number of times it is provided in the lottery game information 50C. This provision ratio is, for example, a value obtained by dividing the total number of times it is provided by the total number of times it is executed. Specifically, when the total number of times the specific character is provided is 250 and the total number of times the lottery game is executed is 100,000, the management means 54 calculates the provision ratio of the specific character to be 250 / 100,000 (0.25%).

[0054] Furthermore, when a predetermined time arrives, the management means 54 initializes (resets) the number of times the lottery game has been executed and the number of times it has been provided in the lottery game execution information in the player information 50A, and the total number of times it has been executed and the total number of times it has been provided in the lottery game information 50C. Examples of the predetermined time include a set date and time (for example, midnight every day, midnight every Monday), the end of the lottery game, etc.

[0055] The presentation means 56 is a functional means for presenting various information to each player. In this embodiment, the presentation means 56 presents information indicating the provision ratio of a specific character (specific content) according to the total number of executions and the total number of provisionings in the lottery game information 50C to a plurality of players. For example, the presentation means 56 presents the value (probability) of the provision ratio calculated by the management means 54 and a gauge indicating the value to each player on the lottery game execution screen.

[0056] In addition, the notifying means 56 notifies the player that the item will be returned. For example, the notifying means 56 notifies the player of the return of the item by an in-game notice (in-game mail).

[0057] The return means 58 is a functional means for returning items consumed in the lottery game to each player. In this embodiment, when a predetermined time arrives, the return means 58 returns some or all of the items consumed in the lottery game to the player who played the lottery game in accordance with whether a predetermined condition is satisfied. The predetermined condition is that the provision rate of a specific character (specific content) is lower than a predetermined probability corresponding to the lottery probability of the specific character. This predetermined probability may be the same value as the lottery probability of the specific character, or may be a value obtained by adding or subtracting a certain probability (e.g., 0.02%) to the lottery probability of the specific character. For example, when the lottery probability of the specific character is 0.30%, the predetermined probability may be 0.32%, which is obtained by adding a certain probability (e.g., 0.02%) to the lottery probability. Note that when there are multiple specific characters in a certain lottery game, the predetermined probability is a value corresponding to the total value of the lottery probabilities of each specific character. For example, if the probability of one specific character being selected is 0.30% and the probability of another specific character being selected is 0.25%, the predetermined probability may be 0.55%, which is the sum of the respective selection probabilities.

[0058] For example, the return means 58 compares the provision rate of a specific character with a predetermined probability at a predetermined time (e.g., 0:00 every day), and if the provision rate is low, returns to a player who has played a lottery game within a predetermined period (e.g., 24 hours) prior to the predetermined time, some or all of the items consumed by the player in the lottery game. An example of this portion of items is 80% of the items consumed by the player.

[0059] Furthermore, the return means 58 increases the number of items to be returned as the provision rate of a specific character (specific content) is lower than the predetermined probability. For example, when a value (probability) obtained by subtracting the provision rate from the predetermined probability is 0.05% or more, the return means 58 returns all items consumed by the player in the lottery game, when the value is 0.03% or more and less than 0.05%, the return means 58 returns 80% of the items consumed by the player in the lottery game, and when the value is less than 0.03%, the return means 58 returns 60% of the items consumed by the player in the lottery game.

[0060] Furthermore, the return means 58 returns items to a player who has executed the lottery game a predetermined number of times or more and has not been provided with a specific character (specific content). For example, the return means 58 returns some or all of the items consumed in the lottery game to a player who has executed the lottery game a predetermined number of times (e.g., once) or more within a predetermined period (e.g., 24 hours) going back from a predetermined time (e.g., midnight) and has not been provided with a specific character in the lottery game the predetermined number of times. Note that the return means 58 may not return items consumed in the lottery game to a player who has been provided with a specific character in a lottery game within the predetermined period, even if the lottery game has been executed a predetermined number of times or more within the predetermined period.

[0061] Furthermore, the return means 58 returns more items to a player who has been provided with less than a predetermined number of specific characters (e.g., one) than to a player who has been provided with a predetermined number (e.g., one) or more of specific characters (specific content) by playing a lottery game. For example, when returning consumed items to a player who played a lottery game within a predetermined period (e.g., 24 hours) prior to a predetermined time (e.g., midnight), the return means 58 returns 40% of the consumed items to a player who has been provided with one or more specific characters in the lottery game, and returns 80% of the consumed items to a player who has not been provided with any specific characters in the lottery game.

[0062] In addition, the return means 58 returns free items to the player who played the lottery game. For example, if the player consumes five paid items in the lottery game, the return means 58 returns three free items.

[0063] Furthermore, the return means 58 returns a larger number of free items as the number of paid items consumed in the lottery game increases. For example, if the items consumed by the player in the lottery game are one paid item and four free items, the return means 58 returns one item, and if the consumed items are two paid items and three free items, the return means 58 returns two items. In other words, the return means 58 returns items (e.g., free items) in a number corresponding to the number of paid items consumed in the lottery game (e.g., the same number as the number of paid items consumed).

[0064] <Process flow related to lottery games> 5 is a flow chart showing an example of the flow of processing related to the lottery game in the game system according to this embodiment. The processing of the following steps is started, for example, when a player issues an operational instruction to select one lottery game (lottery game A) from a menu screen of the lottery game. The order and contents of the following steps can be changed as appropriate.

[0065] (Step SP10) The management means 54 refers to the total number of times a lottery game (lottery game A) has been played and the total number of times it has been provided in the lottery game information 50C, and calculates the providing ratio of the specific character. Specifically, the management means 54 divides the total number of times it has been provided by the total number of times it has been played to calculate the actual providing ratio of the specific character. Then, the process proceeds to step SP12.

[0066] (Step SP12) The presentation means 56 displays a lottery game execution screen 60 on the touch panel 32 .

[0067] FIG. 6 is a diagram showing an example of a lottery game execution screen 60 according to the present embodiment.

[0068] 6, the lottery game execution screen 60 is provided with a lottery target information area 62, a single lottery instruction button 64, and a continuous lottery instruction button 66. The lottery target information area 62 displays specific characters included in the lottery target character group, and the selection probability (theoretical selection probability) and provision rate (actual provision rate) of the specific characters. This provision rate is a value calculated in step SP10. The single lottery instruction button 64 is a button for instructing the execution of a single lottery. The continuous lottery instruction button 66 is a button for instructing the execution of continuous lotteries.

[0069] Returning to FIG. 5, the process proceeds to step SP14.

[0070] (Step SP14) The lottery means 52 accepts a press of the single lottery instruction button or the continuous lottery instruction button on the lottery game execution screen by the player, and then the process proceeds to step SP16.

[0071] (Step SP16) The lottery means 52 refers to the lottery fee for one lottery game (lottery game A) in the lottery game information 50C and consumes (subtracts) items required to execute the lottery from the items owned by the player. For example, when the single lottery instruction button is pressed in step SP14, the lottery means 52 preferentially consumes five paid items from the items owned by the player based on the consumption method of the lottery fee. Also, when the continuous lottery instruction button is pressed in step SP14, the lottery means 52 preferentially consumes 50 paid items from the items owned by the player based on the consumption method of the lottery fee. Next, the selection means 52 refers to the selection target information of one selection game (selection game A) in the selection game information 50C, and performs a selection process to select a character based on the selection probability of each character constituting the selection target character group. For example, when the single selection instruction button is pressed in step SP14, the selection means 52 selects one character from the selection target character group. Also, for example, when the continuous selection instruction button is pressed in step SP14, the selection means 52 selects ten characters continuously from the selection target character group. Next, the selection means 52 provides the selected characters to the player. Specifically, the selection means 52 adds one or more selected characters to the possessed character information of the player information 50A. Then, the process proceeds to the process of step SP18.

[0072] (Step SP18) The management means 54 judges whether or not the one or more characters selected in step SP16 include a specific character. If the judgment is affirmative, the process proceeds to step SP20. On the other hand, if the judgment is negative, the process proceeds to step SP22.

[0073] (Step SP20) The management means 54 increases the number of times one lottery game (lottery game A) is provided in the lottery game execution information of the player information 50A and the total number of times one lottery game is provided in the lottery game information 50C. Specifically, the management means 54 adds the same number (e.g., 1) as the number of specific characters drawn (provided) in step SP16 to the number of times provided and the total number of times provided, respectively. Then, the process proceeds to the process of step SP22.

[0074] (Step SP22) The management means 54 increases the number of times one lottery game (lottery game A) has been played in the lottery game playing information of the player information 50A and the total number of times one lottery game has been played in the lottery game information 50C. Specifically, the management means 54 adds the same number as the number of characters drawn in step SP16 (e.g., 10) to the number of times played and the total number of times played, respectively. Then, the process proceeds to step SP24.

[0075] (Step SP24) The presentation means 56 displays a lottery game result screen 70 on the touch panel 32. The character selected in step SP16 may be displayed between steps SP16 and SP22.

[0076] FIG. 7 is a diagram showing an example of a lottery game result screen 70 according to the present embodiment.

[0077] 7, the lottery game result screen 70 is provided with a lottery result presentation area 72. The lottery-selected characters are displayed in the lottery result presentation area 72. In this lottery result presentation area 72, the specific character is displayed in a manner different from other characters.

[0078] Then, the series of processes shown in FIG. 5 ends.

[0079] <Return process flow> 8 is a flow chart showing an example of the flow of processing related to returning an item in the game system according to this embodiment. The processing of the following steps is started, for example, when a predetermined time (for example, midnight) arrives. The order and contents of the following steps can be changed as appropriate.

[0080] (Step SP30) The management means 54 refers to the total number of times a lottery game (lottery game A) has been played and the total number of times it has been provided in the lottery game information 50C, and calculates the providing ratio of the specific character. Specifically, the management means 54 divides the total number of times it has been provided by the total number of times it has been played to calculate the actual providing ratio of the specific character. Then, the process proceeds to step SP32.

[0081] (Step SP32) The return means 58 judges whether or not a predetermined condition is satisfied. For example, when the provision rate of the specific character calculated in step SP30 is lower than a predetermined probability corresponding to the selection probability (theoretical selection probability) of the specific character, the return means 58 judges the determination as positive. Then, when the determination is judged as positive, the process proceeds to the process of step SP34. On the other hand, when the determination is judged as negative, the process proceeds to the process of step SP40.

[0082] (Step SP34) The return means 58 identifies a player who will return the item. For example, a player who has played the lottery game a predetermined number of times or more within a predetermined period (e.g., 24 hours) prior to a predetermined time (e.g., midnight) is identified as a player who will return the item. Specifically, the return means 58 identifies a player who has played one lottery game a predetermined number of times (e.g., 10 times) or more in the lottery game playing information of the player information 50A as a player who will return the item. Then, the process proceeds to step SP36.

[0083] (Step SP36) The return means 58 determines the number of items (free items) to be returned. For example, the return means 58 increases the number of items to be returned as the provision rate of the specific character calculated in step SP30 becomes lower than the predetermined probability. For example, the return means 58 determines that if the value (probability) obtained by subtracting the provision rate from the predetermined probability is 0.05% or more, the return means 58 returns all items (e.g., 50 items) consumed by the player in one lottery game, if the value is 0.03% or more and less than 0.05%, the return means 58 returns 80% of the items (e.g., 40 items) consumed by the player in the lottery game, and if the value is less than 0.03%, the return means 58 returns 60% of the items (e.g., 30 items) consumed by the player in the lottery game. The return means 58 multiplies the number of executions in the lottery game execution information of the player information 50A by the number of items in the lottery consideration in the lottery game information 50C to determine the total number of items consumed by the player in one lottery game. Then, the process proceeds to step SP38.

[0084] (Step SP38) The presenting means 56 notifies the player identified in step SP34 that the item will be returned. For example, the presenting means 56 notifies the player of the return of the item by an in-game notice (in-game mail). In other words, the presenting means 56 displays a notification screen 80 on the touch panel 32 when the player opens the in-game notice.

[0085] FIG. 9 is a diagram showing an example of a notification screen 80 according to the present embodiment.

[0086] 9, the notification screen 80 has a return notification area 82. The return notification area 82 indicates that the item consumed in the lottery game has been returned in response to the provision rate of the specific character being lower than a predetermined probability.

[0087] Returning to FIG. 8, the process proceeds to step SP40.

[0088] (Step SP40) The management means 54 initializes the number of times one lottery game has been executed and the number of times it has been provided in the player information 50A, and the total number of times one lottery game has been executed and the total number of times it has been provided in the lottery game information 50C. Specifically, the management means 54 assigns 0 to the number of times one lottery game has been executed and the number of times it has been provided, and the total number of times one lottery game has been executed and the total number of times it has been provided, corresponding to all players. Then, the process ends the series of processes shown in FIG. 8.

[0089] <Effects> As described above, in this embodiment, the computer functions as lottery means 52 which executes a lottery game in response to a request from a player, and provides the player with content selected based on the selection probability for each piece of content to be selected, management means 54 which manages the total number of times the lottery game has been executed by multiple players and the total number of times a specific content has been provided in the lottery game, and presentation means 56 which presents to the multiple players information indicating the provision rate of a specific content according to the total number of times it has been executed and the total number of times it has been provided.

[0090] According to this configuration, since it is possible to present each player with information indicating the actual provision ratio of a specific content, it is possible to provide a lottery game that does not cause players to feel distrustful.

[0091] In addition, in this embodiment, the lottery means 52 executes a lottery game by consuming items owned by the player, and causes the computer to function as a return means 58 that returns a part or all of the consumed items to the player who executed the lottery game when a specified time arrives and the provision rate of a specific content is lower than a specified probability corresponding to the lottery probability of the specific content.

[0092] According to this configuration, if the rate of provision of specific content is lower than a predetermined probability corresponding to the lottery probability, some or all of the items consumed in the lottery game are returned to the player, thereby providing a fair lottery game for each player.

[0093] Furthermore, in this embodiment, the return means 58 returns a larger number of items as the provision rate of the specific content becomes lower than the predetermined probability.

[0094] According to this configuration, the lower the rate at which the specific content is provided is compared to the predetermined probability, the greater the number of items returned to the player, making it possible to provide a fair lottery game for each player.

[0095] Furthermore, in this embodiment, the return means 58 returns an item to a player who has played the lottery game a predetermined number of times or more and has not been provided with specific content.

[0096] According to this configuration, since items are returned to players to whom the specific content has not been provided, it is possible to provide a lottery game that is fair to each player.

[0097] Also, in this embodiment, the return means 58 returns more items to a player who has been provided with less than a predetermined number of specific characters than to a player who has been provided with a predetermined number or more of specific content through the execution of the lottery game.

[0098] According to this configuration, a greater number of items are returned to players who were not provided with specific content than to players who were provided with the content, making it possible to provide a fair lottery game for each player.

[0099] In addition, in this embodiment, the items include paid items that the player can acquire by a purchase procedure and free items that the player can acquire by playing the game, and the return means 58 returns the free items to the player who played the lottery game.

[0100] According to this configuration, since free items that can be acquired by playing the game are returned instead of paid items that can be acquired by purchasing procedures, the impact on the profits of the game operator can be reduced.

[0101] In addition, in this embodiment, the lottery means 52 executes the lottery game by consuming only paid items owned by the player.

[0102] According to this configuration, the lottery game is played using only paid items that can be acquired through a purchasing procedure, rather than free items that can be acquired through game play, thereby reducing the impact on the game operator's revenue.

[0103] In addition, in this embodiment, the lottery means 52 executes the lottery game by preferentially consuming paid items over free items owned by the player.

[0104] According to this configuration, the lottery game is played by prioritizing the consumption of paid items that can be acquired through a purchasing procedure over free items that can be acquired through game play, thereby reducing the impact on the game operator's revenue.

[0105] Furthermore, in this embodiment, the return means 58 returns a greater number of free items as the number of paid items consumed increases.

[0106] According to this configuration, the more paid items are consumed in the lottery game, the more free items are returned, so that a fair lottery game can be provided to each player.

[0107] In addition, in this embodiment, the specific content is content whose rarity is equal to or greater than a predetermined value.

[0108] According to this configuration, it is possible to present information indicating the actual provision rate of high rarity content desired by the player in the lottery game, thereby providing a lottery game that does not cause distrust among the player.

[0109] ---Variations--- The present invention is not limited to the above specific examples. In other words, the above specific examples, to which a person skilled in the art has made appropriate design modifications, are also included within the scope of the present invention as long as they have the characteristics of the present invention. In addition, the elements of the above-mentioned embodiment and the modified examples described below can be combined to the extent technically possible, and combinations of these are also included within the scope of the present invention as long as they include the characteristics of the present invention.

[0110] For example, in the above embodiment, the lottery means 52 executes the lottery game by the player consuming an item, but the lottery game may be executed by the player directly paying a fee. In this case, the return means 58 may return a part or all of the charged amount, or may return an item equivalent to the charged amount.

[0111] In the above embodiment, the management means 54 refers to the total number of executions and the total number of provision times of the lottery game in the lottery game information 50C to calculate the provision rate of the specific character, but the management means 54 may refer to the number of executions and the number of provision times of the lottery game execution information in the player information 50A to calculate the provision rate of the specific character corresponding to the player. In this case, the return means 58 returns a part or all of the items consumed in the lottery game to the player when the provision rate of the specific character corresponding to the player is lower than a predetermined probability according to the probability of selection of the specific character. Note that the players to whom the items are returned may be limited to players who have executed the lottery game a predetermined number of times (for example, 100 times) or more.

[0112] In the above embodiment, the presenting means 56 presents information indicating the provision ratio of a specific character to each player on the lottery game execution screen, but the lottery game execution screen may present information indicating the total number of times the lottery game has been executed or the total number of times the specific character has been provided. The presenting means 56 may present information indicating the provision ratio of a specific character only to players who have executed the lottery game a predetermined number of times (e.g., once) or more within a predetermined period of time.

[0113] In the above embodiment, the return means 58 returns items consumed by a player who has played a lottery game within a predetermined period going back from a predetermined time. However, the lower the rarity of each character provided in a lottery game played a predetermined number of times or more within the predetermined period, the more items to be returned. For example, the lower the average value of the rarity of each character provided in a lottery game played a predetermined number of times or more, the more items the return means 58 returns. Specifically, when the average value of the rarity is less than 4.2, the return means 58 returns all items consumed by the player in the lottery game (e.g., 100 items), when the average value is 4.2 or more and less than 4.5, the return means 58 returns 60% of the items consumed by the player in the lottery game (e.g., 60 items), and when the average value is 4.5 or more, the return means 58 returns 20% of the items consumed by the player in the lottery game (e.g., 20 items).

[0114] In the above embodiment, the return means 58 returns free items, but it may return paid items. For example, the return means 58 returns one paid item and two free items to a player who has played a lottery game consuming five paid items. The return means 58 may also provide the player with content other than items. For example, the return means 58 may provide the player with a specific character or a character of the same rarity as the specific character.

[0115] In addition, in the above embodiment, the return means 58 is described as returning some or all of the items consumed in the lottery game to the player, but it may also return more items than the items consumed in the lottery game.

[0116] In the above embodiment, the return means 58 returns items to players who have played the lottery game a predetermined number of times or more, but items may also be given to players who have not played the lottery game. In this case, the return means 58 may give (return) fewer items to players who have not played the lottery game than to players who have played the lottery game. The return means 58 may also limit players to whom items are returned to players who have consumed paid items to play the lottery game a predetermined number of times (e.g., 10 times) or more, players who pay monthly fees, players whose billing amount for the previous month is a predetermined amount or more, etc.

[0117] Furthermore, in the above embodiment, the case where the content is a character has been mainly described, but the content may be items such as weapons and armor, cards, avatars, coins, points, and the like. [Explanation of symbols]
