Description

Program and information processing device

[0001] The present invention relates to a program and an information processing device.

[0002] For example, as disclosed in Patent Document 1 below, a lottery game is known in which content including characters and the like can be acquired by lottery.

[0003] In order to attract new players, game operators may offer lottery games that can be played by new players (hereinafter referred to as "new player lottery games").

[0004] Furthermore, in order to retain existing players, game operators often change lottery games other than new player lottery games (hereinafter referred to as "general lottery games") from time to time. Note that changing a lottery game includes changing some or all of the characters that are the subject of the lottery.

[0005] Patent No. 7414900

[0006] The game operator may wish to change the new player lottery game to be similar to the general lottery game described above, in the hope of achieving a promotional effect to further attract new players.

[0007] However, periodically changing the new player lottery game would require significant development costs and man-hours, and even if the game were changed periodically, new players might be dissatisfied, preferring the characters they had before the change.

[0008] The present invention aims to provide a program and an information processing device that can reduce the possibility of new players becoming dissatisfied while reducing development costs and man-hours.

[0009] In order to solve the above problem, the program of the first aspect of the present invention causes a computer to function as an account generation means for generating an account associated with a player in response to a player's request, an execution means for executing a first lottery game that is common to each player and in which at least one piece of content can be selected by lottery from a first content group, and a second lottery game that is unique to the player for whom the account was generated and in which at least one piece of content can be selected by lottery from a second content group different from the first content group, an identification means for identifying some of the content from the first content group in the first lottery game that was provided during a predetermined period up to the time the account was generated, and a content group generation means for generating the second content group in the second lottery game to include the some of the content identified by the identification means and associated with the account.

[0010] In addition, in a second aspect of the present invention, there are multiple first lottery games, each having at least some of the first content groups that are different from each other, and when a new first lottery game is provided, at least some of the first lottery games that have already been provided become unplayable.

[0011] In addition, in a third aspect of the present invention, when a new first lottery game is provided within a certain period of time from the timing, the identification means newly identifies some content from the first content group in the new first lottery game, and the content group generation means includes the newly identified some content by the identification means in the second content group.

[0012] In addition, in a fourth aspect of the present invention, when the content group generation means includes the part of content newly identified by the identification means in the second content group, it excludes one or more of the part of content that was originally included in the second content group from the second content group.

[0013] In addition, in a fifth aspect of the present invention, the part of content excluded from the second content group by the content group generation means is content that was included in the first content group of the first lottery game that was provided most recently among the first lottery games.

[0014] In addition, in a sixth aspect of the present invention, if a new first lottery game is scheduled to be provided during a period in which the player is able to play the second lottery game, the computer further functions as a notification means for notifying the player of the schedule when a screen requesting the player to play the second lottery game is displayed.

[0015] In addition, in a seventh aspect of the present invention, the computer is further made to function as event generation means that, when the account generation means generates the account, generates an event that grants the player the right to request the execution of the second lottery game depending on the player's playing status.

[0016] In addition, in an eighth aspect of the present invention, the computer is further made to function as event generation means that, when the account generation means generates the account, generates an event in which an item corresponding to the part of the content included in the second content group is granted to the player in accordance with the playing status of the player.

[0017] In a ninth aspect of the present invention, the second lottery game is limited in the number of times and / or period during which it can be played, compared to the first lottery game.

[0018] An information processing device according to a tenth aspect of the present invention comprises an account generation means for generating an account associated with a player in response to a request from the player; an execution means for executing a first lottery game that is common to each player and in which at least one piece of content can be selected from a first content group; a second lottery game that is unique to the player for whom the account was generated and in which at least one piece of content can be selected from a second content group different from the first content group; an identification means for identifying some of the content from the first content group in the first lottery game that was provided during a predetermined period up to the time the account was generated; and a content group generation means for generating the second content group in the second lottery game to include the some of the content identified by the identification means and associated with the account.

[0019] According to the present invention, it is possible to change the new player lottery game while reducing development costs and man-hours, and also to reduce the possibility of new players becoming dissatisfied.

[0041] The speaker 42 has a function of outputting game sounds and the like.

[0042] <Game Overview> The game according to the first embodiment includes a lottery game and quests that allow the player to acquire characters, items, etc. as examples of content. The lottery game may be called gacha, lottery, summoning, etc. The quest may be called dungeon, subjugation, exploration, etc.

[0043] The lottery game according to the first embodiment can be executed by a player selecting one of multiple types of lottery games on a lottery game execution menu screen or the like. In this lottery game, the player can select a single lottery, in which a single lottery is executed, or a continuous lottery, in which ten consecutive lottery draws are executed. This single lottery may be referred to as a single gacha, a single lottery draw, a single summon, or the like. Furthermore, this continuous lottery may be referred to as a 10-consecutive gacha, a 10-time lottery draw, a 10-time summon, or the like. Then, by issuing an instruction (request) to execute a single lottery or a continuous lottery, the player can acquire a character randomly selected from a group of lottery-eligible characters (a group of lottery-eligible content) corresponding to the one lottery game. This lottery game is executed by consuming a fee. This fee may be a paid item (a paid item) or a free item (a non-paid item), etc. Paid items are items that players can acquire through purchase procedures (payment of cash or electronic money, credit card payment, etc.). Examples of paid items include paid stones and paid gacha tickets. Free items are items that players can acquire through gameplay (playing various games). Gameplay includes logging in, clearing quests, completing missions, and interacting with other players who have registered as friends. Examples of free items include free stones and free gacha tickets. Paid items are more valuable than free items. For example, in a lottery game that can be played by consuming only paid items, it is easier to acquire characters with higher rarity (rare value) than in a lottery game that can be played by consuming free items. Paid stones and free stones are sometimes referred to interchangeably as "stones."

[0044] Furthermore, a quest according to the first embodiment is executed by the player selecting one quest from multiple types of quests on a quest menu screen. These quests include normal quests and event quests (also simply referred to as events). Normal quests are quests in which the player clears a playable quest to make the next quest playable. Event quests are quests in which the playable quests change depending on the time of day or period. Each quest is executed by consuming a stamina consumption value associated with the quest from the player's current stamina value. 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 the quest is cleared or retired).

[0045] In addition, in a quest according to the first embodiment, a fighting game is executed in which a team made up of one or more characters owned by the player battles against enemy characters that appear. In this quest, for example, the player instructs the characters making up the team (the characters used) to attack, etc. When the quest is cleared, the player is granted (given) rewards such as free items, game coins, characters, player experience points, etc. Note that free items may not be granted for quests that the player has already cleared.

[0046] <<Update Overview>> In the game according to the first embodiment, updates that add new quests to existing quests and updates that add new characters (content) to existing characters (content) are performed periodically or irregularly. These updates may be referred to as version upgrades, updates, etc. Furthermore, these additions may be referred to as releases, bans, etc. An existing quest refers to a quest that was added before a predetermined time (for example, June 2024). On the other hand, a new quest refers to a quest that was added after the predetermined time. An existing character refers to a character that was added before the preferential period (predetermined period) corresponding to each quest. On the other hand, a new character refers to a character that was added after the preferential period. This preferential period is, for example, a period based on the time when the quest was added (the time when the quest can be executed).

[0047] In the game according to the first embodiment, a new quest becomes available based on an update that adds the new quest. For example, the new quest may be more difficult than an existing quest, with the enemy characters that appear having higher parameters and many gimmicks (e.g., damage floors) that are disadvantageous to the player. If the new quest is a normal quest, the player can play the new quest after the update, provided that he or she has cleared all existing normal quests. Furthermore, if the new quest is an event, the player can play the new quest during a predetermined time period or for a predetermined period after the update.

[0048] Furthermore, in the game according to the first embodiment, new characters (content) become available based on updates that add new characters (content). These new characters include, for example, evolved versions of existing characters. Furthermore, these new characters may have higher parameters or parameter upper limits than existing characters, or may have skills that are advantageous against enemy characters or gimmicks that appear in new quests. After the update, a player can acquire the new characters by playing a lottery game in which the new characters are included as lottery items or by completing a quest (e.g., a new quest) in which the new characters are included as rewards. The player can then use the acquired new characters in quests, missions, and the like.

[0049] <<Overview of Combining>> Combining according to the first embodiment refers to developing one character (possessed content) of the player's owned characters (possessed content) using one character as a source character (source content) and other characters as material characters (material content). The material characters used in the combination are excluded (deleted) from the player's owned characters.

[0050] Furthermore, the synthesis according to the first embodiment includes strengthening synthesis and evolutionary synthesis. Strengthening synthesis is synthesis that changes the parameters (e.g., level) of the original character. Evolutionary synthesis is synthesis that evolves (changes) the original character into a different character.

[0051] The strengthening synthesis according to the first embodiment can be performed by the player selecting an strengthening synthesis menu on the owned character management menu screen. In this strengthening synthesis, a source character and a material character are selected from the characters owned by the player through a selection operation by the player. For example, in the strengthening synthesis, a certain number (e.g., 20 or less) of material characters are selected for one source character.

[0052] In the strengthening synthesis according to the first embodiment, instead of consuming the selected material character, the parameters of the selected source character are changed to give an advantage in the game (e.g., a quest). For example, when a material character of a different type from the source character is strengthened with the source character, the parameters of the source character are increased.

[0053] Furthermore, the evolutionary synthesis according to the first embodiment can be performed by the player selecting an evolutionary synthesis menu on the management menu screen for the owned characters. In this evolutionary synthesis, the player selects a source character and a material character from the characters owned by the player by selecting the source character. For example, in evolutionary synthesis, for one source character, a certain number (e.g., five) of material characters that are pre-associated with the source character are selected.

[0054] Furthermore, in the evolution synthesis according to the first embodiment, instead of consuming the selected material characters, the selected source character is evolved (changed) into another character. In other words, the source character is associated with the character ID of another character through evolution synthesis, and the character's name, image, skills, rarity, etc. change. This source character is referred to as the pre-evolved character. This other character is referred to as the evolved character. In the first embodiment, the evolved character is set to a rarity one level higher than the pre-evolved character, and for example, has a higher upper limit value for parameters than the pre-evolved character.

[0055] <Functional Means> FIG. 4 is a block diagram showing an example of the functional configuration of the server device 10. As shown in FIG.

[0056] 4, the server device 10 includes, as main functional means, a storage means 50, an account generation means 52, an identification means 54, a content group generation means 56, an execution means 58, a provision means 60, an event generation means 62, a notification means 64, and a lottery game generation means 66. Of these, 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.

[0057] The storage means 50 is a functional means for storing player information 50A, character information 50B, item information 50C, lottery game information 50D, and quest information 50E, etc.

[0058] The player information 50A is stored for each player in association with the player's player ID. This player information 50A includes, for example, the player's name and age, owned character information, team information, owned item information, stamina information, and friend information. The owned character information includes the character ID and parameters of each owned character. The parameters include level, hit points, attack power, defense power, etc. The level increases (changes) when a character (original character) gains character experience points through fusion. As the level increases, the hit points, attack power, defense power, character experience points, etc. also increase. The team information includes a predetermined number (e.g., seven) of teams pre-organized by the player. Each team includes, for example, a predetermined number (e.g., three) or less of owned characters pre-selected by the player. The owned item information includes the number of owned items associated with the item IDs of the respective owned items. Examples of such items include paid stones and free stones. The stamina information includes the player's current stamina value and stamina upper limit. The current stamina value is the value consumed when a player performs a quest. This current stamina value increases by a predetermined amount (e.g., 1) over time (e.g., 3 minutes), recovering to the stamina upper limit. The current stamina value is also recovered by an amount equal to the stamina upper limit when the player consumes paid stones, free stones, stamina recovery items, etc. This stamina upper limit increases as the player's player rank increases. The player rank increases when the player earns player experience points, for example, by playing quests. The friend information includes the player IDs of other players who are registered as friends.

[0059] 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, rarity, parameter initial values ​​and upper limit values, skills, and usable period. Rarity includes, for example, a numerical value ranging from 1 to 6. This numerical value may be represented, for example, by the number of stars. For example, characters with high rarity have high parameters and parameter upper limit values. The usable period includes the period when the character became usable, i.e., the period when the character was added. This period is, for example, the period when game operation started or the period when the game was updated. For example, the usable period of character X includes January 2021, when character X was added with the start of game operation.

[0060] The item information 50C is stored for each item in association with the item ID of the item. This item information 50C includes, for example, the name and image of the item, and the availability period. The availability period includes the period when the item became available, i.e., the period when the item was added. This period is, for example, the period when the game operation started or the period when the game was updated. For example, the availability period for item Y includes January 2021, when item Y was added with the start of game operation.

[0061] The lottery game information 50D is stored for each lottery game in association with the lottery game ID of the lottery game. This lottery game information 50D includes, for example, a name (title), an image, lottery target information, and a prize. The lottery target information includes the content ID of each content constituting a content group (plurality of contents) that is the lottery target of the lottery game, and the winning probability associated with the content ID. This lottery target includes multiple contents with different availability periods. Furthermore, for example, if the content is characters, a low probability is set for characters with high rarity, and a high probability is set for characters with low rarity. Note that, in terms of the winning probability, characters (pickup characters) may be set that have a higher winning probability than other characters of the same rarity. The prize includes the number of items (amount consumed) required to execute one lottery.

[0062] In the first embodiment, the lottery games included in the lottery game information 50D include a general lottery game (first lottery game) and a new lottery game (second lottery game).

[0063] The new player lottery game is a lottery game that can be played once or multiple times by a player who creates an account when starting the game for the first time, and is also called a startup gacha. In other words, the new player lottery game is a lottery game that is unique to each player who creates an account.

[0064] The general lottery game is a lottery game other than the above and can be played by all players. In other words, the general lottery game is a lottery game common to all players. In addition, hereinafter, the content group that is the subject of the lottery in the general lottery game will be referred to as the first content group, and the content group that is the subject of the lottery in the new lottery game will be referred to as the second content group.

[0065] The new lottery game may be limited in the number of times it can be played, as compared with the general lottery game, or the period during which it can be played may be limited, as compared with the general lottery game.

[0066] The quest information 50E is stored for each quest (including events) in association with the quest ID of the quest. This quest information 50E includes, for example, the name (title), image, character information, consumed stamina value, clearing conditions, reward information, executable time, and preferential treatment time. The character information includes parameters (level, hit points, etc.) of enemy characters appearing in the quest. The consumed stamina value is the stamina value required to execute the quest. The clearing conditions include the clearing criteria for the quest. Examples of the clearing conditions include reducing the hit points of all enemy characters to 0 or less, or occupying the enemy character's territory. The reward information includes information about the reward to be awarded to the player when the quest is cleared. This reward information includes, for example, the character ID of the reward character, the character's granted level, the grant rate (drop rate) which is the probability of granting the character, the number of game coins, the amount of player experience points, the number of free items, etc. The executable time includes the time when the quest became executable, i.e., the time when the quest was added. This period may be, for example, the time when the game operation started or the time when the game was updated. For example, the executable period for Quest E includes March 2021, when Quest E was added in the first update since the start of game operation. For example, the executable period for Quest G includes October 2021, when Quest G was added in the fifth update since the start of game operation. For example, the executable period for Quest R includes April 2024, when Quest R was added in the 25th update since the start of game operation. The preferential period includes a predetermined period for preferential rewards. In the first embodiment, if the period when a usable character in a quest becomes available is before the predetermined period, the reward for the quest is preferentially treated. For example, the preferential period (predetermined period) for Quest E includes March 2021, the same period as the executable period for Quest E. For example, the preferential period for Quest G includes April 2022, six months after the executable period for Quest G. For example, the preferential period for Quest R includes April 2023, which is one year before the executable period for Quest R.

[0067] The lottery game generation means 66 is a functional means for generating a plurality of general lottery games in which each player can select content by lottery. The generation of this general lottery game also includes the generation of a first content group to be selected by lottery.

[0068] Furthermore, the "plurality of general lottery games" may have a pre-change / post-change relationship with one another. For example, general lottery game C may be a modified version of general lottery game B, and general lottery game B may be a modified version of general lottery game A. In this case, "change" includes a partial or complete change to the content included in the first content group, or a change to specifications such as the layout or lottery method of the lottery game. When a general lottery game is changed, the previous version is no longer displayed, and lotteries for the previous version become unavailable. In other words, when a new general lottery game is provided, the previously provided general lottery games become unavailable. For example, when general lottery game B is provided, general lottery game A becomes unavailable.

[0069] Alternatively, the "plurality of general lottery games" may be general lottery games that are unrelated to each other (independent). In this case, the plurality of general lottery games may be in a state in which lotteries can be executed in parallel.

[0070] Alternatively, with regard to the "plurality of general lottery games" described above, some of them may be in a pre-change / post-change relationship with each other, and the other may be general lottery games that have no relationship with each other (are independent).

[0071] It should be noted that the number of general lottery games may be one instead of multiple.

[0072] The lottery game generation means 66 may also generate a new lottery game. However, the generation of the first content group is performed by the content group generation means 56. Furthermore, once the new lottery game is generated, the content group generation means 56 may only need to update the first content group. (However, the lottery game generation means 66 may also update the layout and lottery policy of the new lottery game every time the content group generation means 56 updates the first content group.)

[0073] The account generation means 52 is a functional means for generating an account associated with a player in response to a request from the player.

[0074] The providing means 60 is a functional means for providing a common general lottery game to each terminal device 12 of each player. Furthermore, when an account for a certain player is generated by the account generating means 52, the providing means 60 provides a new lottery game to the terminal device 12 of the player associated with the account. Furthermore, the providing means 60 provides each quest including an event to the terminal device 12.

[0075] The new player lottery game can select content by lottery in response to a request from a player whose account is associated with the new player by the account generation means 52. The new player lottery game can be played once or multiple times by generating an account.

[0076] The identification means 54 is a functional means for identifying some of the content from among each of the first content groups to be selected in a plurality of general lottery games provided by the providing means 60 during a predetermined period until the time when a player's account is generated by the account generating means 52. However, the first content groups to be selected in the plurality of general lottery games are assumed to have at least some (contents) different from each other.

[0077] Furthermore, the specifying means 54 may specify a portion of the content from each of the first content groups in each of the first lottery games during the predetermined period.

[0078] Furthermore, when a new general lottery game is provided within a certain period (e.g., 30 days) from the time the account is generated by the account generation means 52, the identification means 54 newly identifies some of the content from the first content group of the new general lottery game.

[0079] The "some content" may be, for example, content whose rarity is equal to or greater than a predetermined value. Alternatively, it may be content whose predetermined parameter is equal to or greater than a predetermined value, or content whose level is equal to or greater than a predetermined value. Furthermore, for each of these categories, instead of "equal to or greater than a predetermined value," it may be "a predetermined number from the top among the contents included in the first content group." Furthermore, the "timing" may be, for example, time of day, date, or month. However, if time is used, the predetermined period and the fixed period are calculated in hours; if date is used, the predetermined period and the fixed period are calculated in days; and if month is used, the predetermined period and the fixed period are calculated in months.

[0080] The content group generation means 56 is a functional means for generating, when the identification means 54 identifies content, a second content group to be selected by lottery in the new lottery game so as to include the content identified by the identification means 54. The content group generation means 56 is a functional means for associating the second content group with the player's account generated by the account generation means 52.

[0081] The content group generation means 56 may also update the second content group to include the part of content newly identified by the identification means 54 (within a certain period of time from the time the account was created). In this case, one or more of the parts of content originally included in the second content group may be excluded from the second content group. Furthermore, the content excluded by the content group generation means 56 may be content included in the first content group of the first lottery game that was provided most recently (by the providing means 60) among the general lottery games. The number of excluded contents may be the same as the number of added contents.

[0082] The execution means 58 is a functional means for executing a plurality of general lottery games and a new lottery game in response to a player's request and granting the selected content to the player. The execution means 58 may also be capable of executing a new lottery game in response to a player's request for a certain period of time from the time an account is generated by the account generation means 52. Furthermore, the execution means 58 may also be capable of executing a plurality of general lottery games and a new lottery game once or multiple times. Furthermore, the execution means 58 may also be capable of executing quests, including events generated by the event generation means 62 (described later), in response to a player's request. Each quest is executed based on, for example, parameters of the characters (party members) used.

[0083] The execution means 58 may also provide the player with a reward other than the selected content. For example, the execution means 58 may provide the player with a reward in response to the completion of a quest. The reward may include, for example, free items (free stones or free gacha tickets) or characters.

[0084] The notification means 64 is a functional means for generating and notifying the player of various notification contents. For example, the notification means 64 may generate and notify the player of information such as whether the general lottery game or the new lottery game is playable or whether the general lottery game or the new lottery game is no longer playable. The notification means 64 may also be capable of deleting the generated notification contents.

[0085] The notification may be displayed as part of one of the various operation screens displayed on the display 32A. Alternatively, a pop-up screen may be displayed separately from the display 32A, and the notification may be displayed on the pop-up screen. Furthermore, the notification may be output as a voice or sound from the speaker 42 of the terminal device 12.

[0086] The event generating means 62 is a functional means for generating and updating various quests including events.

[0087] The server device 10 may further include a determination unit and a judgment unit (not shown).

[0088] The determination means is a functional means for determining characters (contents) to be used by the player in each quest. The determination means determines characters to be used in one quest, which is an existing quest, from one or more characters associated with the player. For example, the determination means determines a predetermined number (e.g., three) of characters selected by the player from among the characters owned by the player as characters to be used. Note that characters associated with the player may include, in addition to characters owned by the player, characters owned by other players registered as friends by the player, characters loaned to the player by a game operator, etc. The judgment means is a functional means for making various judgments.

[0089] <<Processing Flow from Account Creation to Execution of New Lottery Game>> An example of the processing from account creation to execution of the new lottery game in the first embodiment will be described below using the flowchart in Fig. 5. Note that the order and content of the following steps can be changed as appropriate.

[0090] (Step SP2) The account generation means 52 generates a new account in association with the player in response to the player's request. After step SP2 is completed, the process proceeds to step SP4.

[0091] (Step SP4) The identification means 54 identifies content having a rarity of a predetermined value or more from each of the first content groups that are the subject of lottery in each first lottery game during a predetermined period until the account is generated by the account generation means 25.

[0092] Here, FIG. 6 is a schematic diagram illustrating an example of the relationship between a predetermined period and a general lottery game held during the predetermined period according to the first embodiment.

[0093] In Figure 6, it is assumed that three lottery games, general lottery game A, general lottery game B, and general lottery game C, are released (provided) in the order listed during the specified period up to the time when the account generation means 52 generates a new account in step SP2 (the time indicated by the arrow ``New account generation'' in the figure).

[0094] As an example, the three lottery games, general lottery game A, general lottery game B, and general lottery game C, are in a relationship of before and after change by the lottery game generation means 66. That is, the general lottery game A is changed by the lottery game generation means 66 to become general lottery game B, and the general lottery game B is changed to become general lottery game C. Therefore, when the general lottery game B is released, the general lottery game A becomes unplayable, and when the general lottery game C is released, the general lottery game B becomes unplayable.

[0095] In this case, the identification means 54 identifies content having a rarity equal to or greater than a predetermined value from among the first content groups that are the subject of lottery for the general lottery game A, the general lottery game B, and the general lottery game C.

[0096] Returning to FIG. 5, after step SP4 is completed, the process proceeds to step SP6.

[0097] (Step SP6) The content group generating means 56 generates a second content group to be selected in the new lottery game linked to the player's account, so as to include the content identified by the identifying means 54.

[0098] 7 is a table showing an example of the winning probability of each content in the second content group according to the first embodiment. In Fig. 7, the left column shows the lottery target characters (characters included in the second content group), the center column shows the general lottery game in which each of the characters was a target of the lottery (included in the first content group), and the right column shows the winning probability of each of the characters.

[0099] 7, the second content group includes characters A and B with a rarity equal to or greater than a predetermined value (high rarity) that were included in the first content group of the general lottery game A, characters C and D with high rarity that were included in the first content group of the general lottery game B, and characters E and F with high rarity that were included in the first content group of the general lottery game C. In addition, in the example of FIG. 7, the winning probability of characters A to F is set to 3% each.

[0100] 7, the second content group includes characters G, H, I, ... whose rarity is less than a predetermined value. Note that the characters G, H, I, ... are not characters identified from each first content group by the identification means 54. For example, the characters G, H, I, ... may be characters with low rarity that are fixedly included in the second content group. Alternatively, the characters G, H, I, ... may be items G, H, I, ... instead of the characters G, H, I, ....

[0101] When the content group generating means 56 generates the second content group, the providing means 60 provides a new lottery game including the second content group to the player's terminal device 12. Returning to Fig. 5, after step SP6 is completed, the processing proceeds to step SP8.

[0102] (Step SP8) A determination means (not shown) determines whether a certain period of time has elapsed since the account creation means 52 created the account. If the determination is affirmative, the process proceeds to step SP10, and if the determination is negative, the process proceeds to step SP12. However, the certain period of time may be calculated in hours, days, or months.

[0103] (Step SP10) The new lottery game is no longer displayed on the terminal device 12, and the new lottery game cannot be played. The notification means 64 notifies the player by means of a screen or sound that the second lottery game cannot be played. After step SP10 is completed, the processing ends.

[0104] (Step SP12) The subsequent process branches depending on whether the lottery game generation means 66 has changed the general lottery game. If it has changed, the process proceeds to step SP14, and if it has not changed, the process proceeds to step SP16.

[0105] (Step SP14) The identification means 54 identifies new content having a rarity equal to or greater than a predetermined value from the first content group for the new general lottery game after the change. The content group generation means 56 also updates the second content group to include the content newly identified by the identification means 54. After step SP14 is completed, the process proceeds to step SP16.

[0106] (Step SP16) The subsequent processing branches depending on whether or not a request to play a new lottery game from the player has been accepted. The request is made, for example, by the player operating the touch sensor 32B of the terminal device 12. If the request has been accepted, the processing proceeds to step SP18; if not, the processing returns to step SP8.

[0107] (Step SP18) The execution means 58 executes the new lottery game. The content that is won is awarded to the player.

[0108] Here, FIG. 8 is a diagram showing an example of a new lottery request screen 70 according to the first embodiment of the present invention.

[0109] When the new lottery request screen 70 shown in FIG. 8 is displayed on the display 32A of the terminal device 12, the player operates (e.g., presses) the lottery execution button 76 to request execution. In response to this request, the execution means 58 executes the new lottery game. While the new lottery game may be executed multiple times, it is assumed here that it is executed once. Since the new lottery game is also referred to as a startup gacha, the "startup gacha" is written at the top of the new lottery request screen 70 as an example. Furthermore, the new lottery request screen 70 displays six featured characters 74 (e.g., content with a rarity equal to or greater than a predetermined value) among the characters included in the second content group. Furthermore, the new lottery request screen 70 includes a provision rate display button 72. When the player operates (e.g., presses) the provision rate display button 72, a list of winning probabilities for each content included in the second content group (see, e.g., FIG. 7) is displayed.

[0110] Returning to FIG. 5, after step SP18 is completed, the process ends.

[0111] Effect: In the program according to the first embodiment, a computer program functions as: account generation means 52 for generating an account associated with a player in response to a player's request; execution means 58 for executing a first lottery game (general lottery game) common to each player, in which at least one piece of content can be selected from a first content group; and a second lottery game (new lottery game) specific to the player for whom the account was generated, in which at least one piece of content can be selected from a second content group different from the first content group. Identification means 54 for identifying some content from the first content group in the first lottery game provided during a predetermined period leading up to the time the account was generated. Content group generation means 56 for generating a second content group in the second lottery game to include some of the content identified by the identification means 54 and associates the second content group with the account. This configuration automates the generation and modification of the second content group, thereby reducing development costs and man-hours. Furthermore, since the second content group includes content identified from the first content group in the first lottery game held during the predetermined period, the risk of new players becoming dissatisfied is reduced.

[0112] Furthermore, in the program according to the first embodiment, there are multiple first lottery games, each of which has a first content group that is at least partially different from the others, and when a new first lottery game is provided, at least some of the first lottery games that have already been provided become unplayable. With this configuration, players are no longer able to play past first lottery games, which motivates them to actively play current first lottery games (before they become unplayable). Furthermore, in a specification in which the first lottery game is changed sequentially in this way, it is possible to reduce the development costs and man-hours associated with the second lottery game, while minimizing the risk of dissatisfaction among new players who, for example, wanted the content before the change.

[0113] Furthermore, in the program according to the first embodiment, if a new first lottery game is provided within a certain period of time from the timing described above, the identification means 54 newly identifies some content from the first content group in the new first lottery game, and the content group generation means 56 includes the newly identified some content in the second content group. According to this configuration, if the second content group does not include content that attracts the interest of a new player, the new player can play the second lottery game after the second content group is changed, thereby increasing the motivation of the new player. Furthermore, since the change of the second content group can be automated, development costs and man-hours can be reduced.

[0114] Furthermore, in the program according to the first embodiment, when the content group generation means 56 includes some of the content newly identified by the identification means 54 in the second content group, it excludes one or more pieces of content that were originally included in the second content group from the second content group. According to this configuration, when new content is added to the second content group, the previous content is excluded from the second content group, so that a later execution of the second lottery game is not overly advantageous over an earlier execution, thereby maintaining game balance. Furthermore, by making the number of newly added content and the number of excluded content and their winning probabilities equal, there is no need to review or revise the winning probabilities for the entire second content group from scratch, thereby reducing costs and man-hours.

[0115] Furthermore, in the program according to the first embodiment, some of the content excluded from the second content group by the content group generation means 56 is content that was included in the first content group of the first lottery game that was provided the earliest among the first lottery games. With this configuration, when new content is to be included in the second content group, the content that was included in the second content is excluded in order starting with the oldest content, thereby equalizing the period of time that each piece of content included in the second content has been included in the second content group, and therefore it is possible to prevent an advantage or disadvantage in the lottery from arising depending on the timing of account generation for a new player.

[0116] Furthermore, in the program according to the first embodiment, the number of times and / or period that the second lottery game can be played is more limited than that of the first lottery game. With this configuration, the number of times / period that the second lottery game (new player lottery game) can be played from the time a player creates an account is more limited than that of the first lottery game (general lottery game), and therefore the second lottery game can be seen as one prepared for new players.

[0117] The information processing device according to the first embodiment also includes account generation means 52 for generating an account associated with a player in response to a player's request; execution means 58 for executing a first lottery game common to each player, in which at least one piece of content can be selected by lottery from a first content group; a second lottery game specific to the player for whom the account was generated, in which at least one piece of content can be selected by lottery from a second content group different from the first content group; identification means 54 for identifying some content from the first content group in the first lottery game provided during a predetermined period up to the time the account was generated; and content group generation means 56 for generating a second content group in the second lottery game to include some of the content identified by the identification means 54 and associating the second content group with the account. This configuration automates the generation and modification of the second content group, thereby reducing development costs and man-hours. Furthermore, the second content group includes content identified from the first content group of multiple first lottery games held during a predetermined period, thereby reducing the risk of dissatisfaction among new players.

[0118] Second Embodiment Next, a second embodiment of the present invention will be described. Note that, in the following, descriptions of the same parts as in the first embodiment will be omitted as appropriate, and the description will focus on the differences.

[0119] <Functional configuration of the server device> In the second embodiment of the present invention, if a new general lottery game is scheduled to be provided by the providing means 60 during a period in which the player is able to play the new lottery game, the notification means 64 is a functional means that notifies the player of the schedule when a screen for the player to request playing the new lottery game is displayed on the display 32A of the terminal device 12.

[0120] The notification may be written on the operation screen for the new lottery game displayed on the display 32A, for example. Alternatively, a pop-up screen may be displayed on the display 32A separately from the current screen, and the notification may be written on the pop-up screen. Furthermore, the notification may be output as a voice or sound from the speaker 42 of the terminal device 12.

[0121] <<Processing Flow from Account Creation to Execution of New Lottery Game>> An example of processing from account creation to execution of new lottery game in the second embodiment will be described below using the flowchart in Fig. 9. Note that the order and content of the following steps can be changed as appropriate.

[0122] (Step SP22) The account generation means 52 generates a new account in association with the player in response to the player's request. After step SP22 is completed, the process proceeds to step SP24.

[0123] (Step SP24) The identification means 54 identifies content whose rarity is equal to or greater than a predetermined value from among each of the first content groups that are to be selected in each general lottery game during a predetermined period until the account is generated by the account generation means 25. After step SP24 is completed, the process proceeds to step SP26.

[0124] (Step SP26) The content group generation means 56 generates a second content group to be entered into the new lottery game linked to the player's account, by including the content identified by the identification means 54. Once the content group generation means 56 has generated the second content group, the new lottery game including the second content group is provided to the player's terminal device 12 by the providing means 60. After step SP26 is completed, the process proceeds to step SP28.

[0125] (Step SP28) A determination means (not shown) determines whether a certain period of time has elapsed since the account creation means 52 created the account. If the determination is affirmative, the process proceeds to step SP20, and if the determination is negative, the process proceeds to step SP22. However, the certain period of time may be calculated in hours, dates, or months.

[0126] (Step SP30) The new lottery game is no longer displayed on the terminal device 12, and the new lottery game cannot be played. The notification means 64 notifies the player by means of a screen or sound that the second lottery game cannot be played. After step SP30 is completed, the processing ends.

[0127] (Step SP32) The subsequent process branches depending on whether or not the providing means 60 plans to change the general lottery game. If it is planned, the process proceeds to step SP46, and if it is not planned, the process proceeds to step SP34.

[0128] (Step SP34) The notification means 64 generates notification content. This notification content is to inform the user that changes are planned for the general lottery game. After step SP34 is completed, the process proceeds to step SP36.

[0129] (Step SP36) The subsequent process branches depending on whether or not the general lottery game has been changed by the lottery game generation means 66. If it has been changed, the process proceeds to step SP42; if it has not been changed, the process proceeds to step SP38.

[0130] (Step SP38) The subsequent process branches depending on whether the new lottery request screen 70 is displayed. If it is displayed, the process proceeds to step SP40; if it is not displayed, the process returns to step SP36.

[0131] (Step SP40) The notification means 64 notifies the player of the notification content generated in step SP34. After step SP40 ends, the process proceeds to step SP46.

[0132] (Step SP42) The identification means 54 identifies new content having a rarity equal to or greater than a predetermined value from the first content group for the new general lottery game after the change. The content group generation means 56 also updates the second content group to include the content newly identified by the identification means 54. After step SP42 is completed, the process proceeds to step SP44.

[0133] (Step SP44) The notification means 64 deletes the notification content generated in step SP34. After step SP44 is completed, the process proceeds to step SP46.

[0134] (Step SP46) The subsequent process branches depending on whether or not a request to run a new lottery game has been received from the player. If the request has been received, the process proceeds to step SP48; if not, the process returns to step SP28.

[0135] (Step SP48) The execution means 58 executes the new lottery game. The content that the player wins is awarded to the player. After step SP48 is completed, the process ends.

[0136] Effect: In the program according to the second embodiment, if a new first lottery game is scheduled to be offered during a period during which the player can play the second lottery game, the computer further functions as a notification unit 64 that notifies the player of the scheduled offering when a screen for the player to request playing the second lottery game is displayed. Some new players have low motivation to play games. Such players are unlikely to actively display and check screens such as notices on the display 32A of the terminal device 12. Therefore, according to the above configuration, while a screen requesting the playing of a lottery for the second lottery game (new lottery request screen 70) is displayed, the notification unit 64 notifies the player of information about the first lottery game that includes new content in the first content group on the screen or a pop-up screen. This allows the player to passively check this information, thereby improving convenience. Furthermore, this new content is not only included in the first content group, but also included in the second content group if identified by the identification unit 54. Therefore, if a new player becomes interested in this new content, he or she can request to play the second lottery game after this new content is included in the second content group, thereby further increasing the motivation of the new player.

[0137] Third Embodiment Next, a third embodiment of the present invention will be described. Note that, in the following, descriptions of the same parts as in the first and second embodiments will be omitted as appropriate, and the description will focus on the differences.

[0138] <Functional configuration of the server device> In the third embodiment of the present invention, when the account generation means 52 generates an account, the event generation means 62 generates an event that grants the player the right to request the execution of a new lottery game, depending on the player's playing status.

[0139] It should be noted that "according to the playing situation" may be "when a predetermined condition is met." Furthermore, this predetermined condition may be, for example, the start of an event itself.

[0140] <<Processing Flow from Account Creation to Execution of New Lottery Game>> An example of processing from account creation to execution of new lottery game in the third embodiment will be described below using the flowchart in Fig. 10. Note that the order and content of the following steps can be changed as appropriate.

[0141] (Step SP52) The account generation means 52 generates a new account in association with the player in response to the player's request. After step SP52 is completed, the process proceeds to step SP54.

[0142] (Step SP54) The identification means 54 identifies content whose rarity is equal to or greater than a predetermined value from among each of the first content groups that are to be selected in each first lottery game during a predetermined period until the account is generated by the account generation means 25. After step SP54 is completed, the process proceeds to step SP56.

[0143] (Step SP56) The event generating means 62 generates an event that grants the player the right to request the execution of a new lottery game, depending on the player's playing status. After step SP56 ends, the processing proceeds to step SP58.

[0144] (Step SP58) A request to execute an event from the player is accepted. The request may be made, for example, by operating (pressing, etc.) a dedicated button (not shown) on the home screen displayed on the terminal device 12. After step SP58 ends, the processing proceeds to step SP60.

[0145] (Step SP60) The execution means 58 executes the event. This event was generated by the event generation means 62 in step SP56. After step SP60 ends, the process proceeds to step SP62.

[0146] (Step SP62) A predetermined condition is satisfied in the event executed in step SP60 by the player's operation. After step SP62 ends, the processing proceeds to step SP64.

[0147] (Step SP64) The content group generation means 56 generates a second content group to be entered into the lottery for the new player lottery game linked to the player's account, by including the content identified by the identification means 54. Once the content group generation means 56 has generated the second content group, the new player lottery game including the second content group is provided to the player's terminal device 12 by the providing means 60. After step SP64 is completed, the processing proceeds to step SP66.

[0148] (Step SP66) A determination means (not shown) determines whether a certain period of time has elapsed since the account generation means 52 generated the account in step SP52. If the determination is affirmative, the process proceeds to step SP68, and if the determination is negative, the process proceeds to step SP70. However, the certain period of time may be calculated in hours, or may be calculated in days or months. Furthermore, the certain period of time may not be counted from the time the account generation means 52 generated the account in step SP52, but may be counted from the time a predetermined condition is satisfied in step SP62.

[0149] (Step SP68) The new lottery game is no longer displayed on the terminal device 12, and the new lottery game is no longer playable. The notification means 64 notifies the player by means of a message on the screen, a sound, or the like that the second lottery game is no longer playable. After step SP68 is completed, the processing ends.

[0150] (Step SP70) The subsequent processing branches depending on whether or not the general lottery game has been changed by the lottery game generation means 66. If it has been changed, the processing proceeds to step SP72, and if it has not been changed, the processing proceeds to step SP74.

[0151] (Step SP72) The identification means 54 identifies new content having a rarity equal to or greater than a predetermined value from the new first content group for the general lottery game after the change. The content group generation means 56 also updates the second content group to include the content newly identified by the identification means 54. After step SP72 is completed, the process proceeds to step SP74.

[0152] (Step SP74) The subsequent processing branches depending on whether or not a request to run a new lottery game has been received from the player. If it has been received, the processing proceeds to step SP76, and if it has not been received, the processing returns to step SP66.

[0153] (Step SP76) The execution means 58 executes the new lottery game. The content that the player wins is awarded to the player. After step SP76 is completed, the processing ends.

[0154] <Effects> The program according to the third embodiment of the present invention causes the computer to further function as event generation means 62 that generates an event that grants a player the right to request execution of a second lottery game, depending on the player's play status, when the account generation means 52 generates an account. With this configuration, it becomes possible to execute the second lottery game (new player lottery game) depending on the play status of the event, which increases the likelihood that new players will play the event, and it is possible to convey the interest of the game to new players through playing the event.

[0155] Fourth Embodiment Next, a fourth embodiment of the present invention will be described. Note that, in the following, descriptions of the same parts as those in the first, second, and third embodiments will be omitted as appropriate, and the description will focus on the differences.

[0156] <Functional Configuration of Server Device> In the fourth embodiment of the present invention, when the account generation means 52 generates an account, the event generation means 62 generates an event that grants an item corresponding to some of the content included in the second content group to the player in accordance with the player's play status.

[0157] It should be noted that "some of the content included in the second content group" refers to content identified from the first content group by the identification means 54, and as described in each embodiment, may be, for example, content whose rarity is equal to or greater than a predetermined value.

[0158] In addition, in the fourth embodiment, when the second content group is updated by the content group generation means 56, the event generation means 62 updates the event that has been generated once so that items corresponding to new content included in the updated second content group are also added.

[0159] In addition, if the content is a character, the above-mentioned item may be something that improves the character's basic status, or something that improves the status when equipped by the character, such as a weapon or armor.

[0160] <<Processing Flow from Account Creation to Execution of New Lottery Game>> An example of processing from account creation to execution of new lottery game in the fourth embodiment will be described below using the flowchart in Fig. 11. Note that the order and content of the following steps can be changed as appropriate.

[0161] (Step SP82) The account generation means 52 generates a new account in association with the player in response to the player's request. After step SP82 is completed, the process proceeds to step SP84.

[0162] (Step SP84) The identification means 84 identifies content whose rarity is equal to or greater than a predetermined value from among each of the first content groups that are to be selected in each first lottery game during a predetermined period until the account is generated by the account generation means 25. After step SP84 is completed, the process proceeds to step SP86.

[0163] (Step SP86) The content group generation means 56 generates a second content group to be entered into the lottery for the new player lottery game linked to the player's account, by including the content identified by the identification means 54. Once the content group generation means 56 has generated the second content group, the new player lottery game is provided to the player's terminal device 12 by the providing means 60. After step SP86 is completed, the process proceeds to step SP88.

[0164] (Step SP88) The event generation means 62 generates an event that grants the player an item corresponding to content included in the second content group and having a rarity of a predetermined value or more, depending on the player's play status. After step SP88 is completed, the processing proceeds to step SP90.

[0165] (Step SP90) A determination means (not shown) determines whether a certain period of time has elapsed since the account creation means 52 created the account. If the determination is affirmative, the process proceeds to step SP92, and if the determination is negative, the process proceeds to step SP94. However, the certain period of time may be calculated in hours, dates, or months.

[0166] (Step SP92) The new lottery game is no longer displayed on the terminal device 12, and the new lottery game cannot be played. The notification means 64 notifies the player by means of a screen or sound that the second lottery game cannot be played. After step SP92 is completed, the processing ends.

[0167] (Step SP94) The subsequent process branches depending on whether or not the general lottery game has been changed by the lottery game generation means 66. If it has been changed, the process proceeds to step SP96, and if it has not been changed, the process proceeds to step SP100.

[0168] (Step SP96) The identification means 54 identifies new content having a rarity equal to or greater than a predetermined value from the first content group for the new general lottery game after the change. The content group generation means 56 also updates the second content group to include the content newly identified by the identification means 54. After step SP96 is completed, the process proceeds to step SP98.

[0169] (Step SP98) The event generation means 62 updates the content of the event so that items corresponding to content with a rarity of a predetermined value or higher, included in the second content group updated in step SP96, can be given to the player in accordance with the player's playing status. After step SP98 is completed, the processing proceeds to step SP100.

[0170] (Step SP100) The subsequent processing branches depending on whether or not a request to run a new lottery game has been received from the player. If the request has been received, the processing proceeds to step SP102, and if the request has not been received, the processing returns to step SP90.

[0171] (Step SP102) The execution means 58 executes the new lottery game. The content that is won is awarded to the player. After step SP102 ends, the process proceeds to step SP104.

[0172] (Step SP104) A request to execute an event from the player is accepted. The request may be made by, for example, operating (pressing, etc.) a dedicated button (not shown) on the home screen displayed on the terminal device 12.

[0173] (Step SP106) The execution means 58 executes the event. When a predetermined condition is met in the event, an item corresponding to content included in the second content group and having a rarity equal to or greater than a predetermined value is given to the player. After step SP104 ends, the processing ends. The processing proceeds to step SP106.

[0174] <Effects> In the program according to the fourth embodiment, the computer further functions as event generation means 62 that generates an event for granting items corresponding to some of the content included in the second content group to the player in accordance with the player's play status when the account generation means 52 generates an account. With this configuration, if an old content is won as a result of executing the second lottery game, it is possible to prevent a situation in which the item corresponding to that content (such as an item that increases the basic status of the content (such as the Secret Book of XX)) no longer exists in the game.

[0175] == ...

[0176] For example, in steps SP12 and SP14 of the first embodiment and the corresponding steps of each embodiment, whether to update the second content group is determined depending on whether the lottery game generation means 66 has changed the general lottery game, but instead, the subsequent processing may branch depending on whether the providing means 60 has provided (will provide) a new general lottery game. Similarly, in step SP32 of the second embodiment, the subsequent processing may branch depending on whether the providing means 60 plans to provide a new general lottery game, rather than whether the lottery game generation means 66 plans to change the general lottery game.

[0177] In each embodiment, it has been explained that creating an account allows a new player to play a lottery game, but a time limit may be added (e.g., 30 days), or a number of times may be limited (e.g., once), or both of these may be limited (e.g., 30 days and once).

[0178] Furthermore, the winning probabilities of some of the content included in the second content group (such as content with a rarity equal to or greater than a predetermined value) may not be uniform, as shown in Figure 7. Specifically, the winning probability may be higher for older content, or conversely, the winning probability may be higher for newer content. Furthermore, the temporal definition of "old" or "latest" for content may be determined based on the timing when the content was included in each content group, or may be determined based on the date the content itself was released (provided).

[0179] Furthermore, as described in each embodiment, when the second content group is updated to include new content, the player may decide for himself or herself which content to exclude.

[0180] Furthermore, an expiration date may be set for an item provided in the event described in the fourth embodiment. The expiration date may be counted, for example, from the moment the player starts the event, or from the moment the event generation means 62 generates the event. This counting may be done in hours, days, months, or the like. Furthermore, when the second content group is updated to include new content, the counting may start from the moment the new content is included.
