[First Embodiment]

[Game Overview]
First, an outline of an example of the game according to the present embodiment will be described. The game which concerns on this embodiment is a game played using the game object which a user possesses, for example, is a battle game which battles with an opponent. A game object is a card corresponding to each of a plurality of characters, for example. A character is a person, an animal, an object (for example, a vehicle) or the like appearing in a game. A card is an entity that represents a character appearing in a game and is an example of an object that is recognized by a user by an image (such as a text, a still image, or a moving image). Specifically, the card is a card representing a character that battles with an enemy character that is an opponent in the game, and is displayed as an image on the game screen.

  Although a battle game is taken as an example here, the game is not limited to a battle game, and may be another type of game such as a baseball game, a soccer game, an RPG game, or a breeding game. Further, the game object is not limited to the card, and may be other objects such as a medal or a figure representing the character itself, or may be displayed as an image on the game screen like the card. .

  In the battle game according to the present embodiment, a plurality of cards that can be used for the battle are given to the user as the game progresses. For example, a card is given to a user as a reward when winning a game battle, or given to a user by performing a card lottery. The user possesses a plurality of given cards and can select a character card to be battled from among the possessed cards. Cards include those indicating weapons and armor that have an effect on the attack and defense of characters in battles, in addition to those indicating characters. The user possesses a card representing a weapon or armor in the same manner as a card representing a character, and can select a card to be used for a battle from the possessed cards.

  For example, the user can acquire a lottery right that allows a card lottery as a login reward. The login reward is a reward given to the user due to the user logging into the game. For example, with a maximum of once per day (for example, when logging in for the first time in a day), a login reward is given to a user who has logged into the game. That is, since the reward is given by the user logging in to the game at least once a day, for example, the user is encouraged to log in every day and the user continues to play the game. It is a measure to improve.

  In the lottery right given as the login reward, the type of the card given by the lottery and the lottery probability are set. For example, in the lottery right, a lottery probability that a character card associated with a specific rarity is lottery is set. The rarity is an index indicating the rarity (rareness) of each card. For example, the higher the rarity card, the higher the attack power and defense power, or the higher the upper limit value. Here, there are four types of cards: normal cards, rare cards, S rare cards, and SR rare cards. Rare cards are better than normal cards, S rare cards are rare cards, and SR rare cards are rarer than S rare cards. Suppose it is a high card.

  Further, the lottery right based on the login reward can be acquired by the user or can be suspended without being acquired. If it is suspended, the lottery probability of the lottery right by the login reward will increase. In other words, by acquiring the lottery right, the user can draw a card of a specific rarity with the lottery probability set in the lottery right, and hold it without acquiring the lottery right. At the time of a login reward, a lottery right with an increased lottery probability can be acquired.

  Here, holding without drawing lottery rights means that lottery rights based on the current login reward will not be acquired (cannot be acquired later), and lottery rights based on the next login reward (the lottery probability has increased from this time) It means carrying over to lottery right. In addition, it is good also as making it the state which can acquire the lottery right later, without acquiring this lottery right temporarily without acquiring a lottery right.

  FIG. 1 is a diagram illustrating an example of a login reward screen according to the present embodiment. The illustrated login reward screen G10 is a screen on which a lottery ticket capable of acquiring a lottery right is presented as a login reward. For example, the login reward screen G10 is displayed in response to the first login to the game on the first day of the event period in which the login reward is granted. The The login reward screen G10 includes information K11 indicating that it is today's login reward and a present of a lottery ticket, and a lottery ticket K12 of a lottery right in which a card of a rare card or higher is drawn with a lottery probability of 10%. It is displayed. Further, on the login reward screen G10, a button B1 and a button B2 are displayed as operators that allow the user to select whether or not to acquire the lottery right by the lottery ticket K12. The button B1 is displayed as “Receive”, and is an operator that selects acquisition of a lottery right by the lottery ticket K12. On the other hand, the button B2 is displayed as “not yet received”, and is an operator that selects to hold without acquiring the lottery right by the lottery ticket K12.

  For example, when the user performs an operation (for example, a tap operation) on the button B1, the lottery right based on the lottery ticket K12 is given to the user, and the conditions set for the lottery right (the card of the rare card or higher is the lottery probability). Card lottery based on 10%). On the other hand, when the user performs an operation (for example, a tap operation) on the button B2, the lottery right by the lottery ticket K12 is not given to the user, and the lottery right of the lottery ticket K12 is set in the next login reward. The condition is changed. The condition to be changed is, for example, a lottery probability, and the next lottery probability is higher than the current lottery probability.

  FIG. 2 is a diagram showing an example of the next login reward screen after being held. For example, after holding without acquiring the lottery right on the login reward screen G10 shown in FIG. It is a screen on which a lottery ticket capable of acquiring a lottery right as a login reward is presented when logging in. In the illustrated login reward screen G20, the lottery probability is increased by 5% with respect to the login reward screen G10 of FIG. On the login reward screen G20, information K21 indicating that it is today's login reward and that the lottery probability of the lottery ticket has increased (in this case, 5% UP), and a card with a rare card or higher are drawn with a lottery probability of 15%. The lottery ticket K22 of the lottery right is displayed. Further, on the login reward screen G20, buttons B1 and B2 are displayed in the same manner as in FIG. 1 as operators that allow the user to select whether or not to acquire a lottery right based on the lottery ticket. The user can select whether to acquire the lottery ticket K22 (lottery right) with the increased lottery probability or to hold it without acquiring it.

  As described above, in the present embodiment, in the login reward, the user acquires the lottery right that can perform the card lottery, or the lottery right with an increased lottery probability can be acquired with the next login reward instead of not acquiring it. Providing users with the choice of This makes it possible to respond to both the user's request for card lottery at each login reward and the user's request for card lottery after raising the lottery probability. Can be granted. Hereinafter, the configuration of the present embodiment will be described in detail.

[Function configuration]
Next, with reference to FIG. 6, the functional configuration of the user terminal 10 and the game server 30 included in the game system 1 will be described. FIG. 6 is a block diagram illustrating an example of the configuration of the user terminal 10 and the game server 30 according to the present embodiment. First, the configuration of the game server 30 will be described.

[Functional configuration of user terminal 10]
First, the functional configuration of the user terminal 10 will be described.
The user terminal 10 includes a game control unit 110 as a functional configuration realized by the CPU 11 executing a game control program stored in the storage unit 15. The game control unit 110 executes game processing based on the game control program in response to a user operation on the input unit 13. For example, the game control unit 110 executes a battle game process, and displays various game images according to the battle game process on the display unit 14 as a game screen. Various game screens include a home screen displayed when the game is started, a card selection screen for selecting a card to be used for a battle from possession cards, an item purchase screen for purchasing items used in the game, enemy characters And battle screens for performing battles are included. In addition, the various game screens include a login reward screen (see FIGS. 1 and 2) that can acquire a reward resulting from logging in.

  For example, on the home screen, an operation button is displayed as an operator that makes a transition to a card selection screen, an item purchase screen, a battle screen, or the like. The game control unit 110 transitions to each screen in accordance with a user operation on the operation button corresponding to each screen displayed on the home screen, and executes processing corresponding to each screen. Moreover, when the game control part 110 logs in to a game for the first time on the first day of the event period to which a login reward is given, it changes to the login reward screen G10 (refer FIG. 1), and performs the process regarding a login reward. Here, the functional configuration of the process related to the login reward executed by the game control unit 110 will be described.

  The game control unit 110 includes a login information notification unit 111, a reward processing unit 112, and a display control unit 113. When the login information notification unit 111 logs in to the game based on a user operation, the login information notification unit 111 transmits login notification information indicating that the user has logged in to the game server 30 via the communication unit 12. The login notification information includes user identification information, user terminal 10 identification information, game identification information, and the like.

  When the game server 30 determines that the reward reward processing unit 112 is the target of the login reward based on the login notification information transmitted by the login information notification unit 111, the reward processing unit 112 provides information to the user regarding the login reward (the login reward). Get presentation information). The login reward presentation information is information on a lottery right that can be acquired by the user as a login reward, and includes information on the type of a lottery target card, a lottery probability, and the like.

  The display control unit 113 transitions the display screen of the display unit 14 to a login reward screen (for example, the login reward screens G10 and G20 in FIGS. 1 and 2) based on the login reward presentation information acquired by the reward processing unit 112. The display image of the login reward screen may be generated by the display control unit 113 based on the login reward presentation information, or may be generated by the game server 30 as the login reward presentation information.

  Further, based on the user's operation on the login reward screen (for example, the login reward screens G10 and G20 in FIGS. 1 and 2), the reward processing unit 112 displays information indicating whether or not the user has acquired the lottery right as a communication unit. 12 to the game server 30. For example, when the user performs an operation of acquiring the lottery right, the reward processing unit 112 transmits information indicating that the lottery right has been acquired to the game server 30. On the other hand, when the user holds the lottery right without acquiring the lottery right, the reward processing unit 112 transmits information indicating that the lottery right is held to the game server 30.

  The game control unit 110 transmits various setting information and history information corresponding to the game processing to the game server 30 via the communication unit 12, and transmits various setting information and history information to the communication unit 12 as necessary. Via the game server 30. For example, the lottery right information acquired by the user is associated with the user identification information in the game server 30, and the game control unit 110 acquires the related information from the game server 30, thereby executing the card lottery with the lottery right. Is possible.

[Functional configuration of game server 30]
Next, the functional configuration of the game server 30 will be described.
The game server 30 includes a server control unit 310 as a functional configuration realized by the CPU 11 executing a program stored in the storage unit 35. The server control unit 310 controls each unit of the game server 30. For example, the server control unit 310 acquires user information from the user terminal 10 via the communication unit 32 in response to a request from the user terminal 10 and stores the acquired user information in the storage unit 35. Here, the user information includes, for example, user identification information. The user identification information is a user ID uniquely assigned to each user. The user ID is stored in association with the user's login history, various parameters in the user's game, a character card that the user can use in the game, a lottery right acquired by the user, and the like. The user information is not limited to the user ID but may be a user name or the like as long as the user can be identified.

  Further, the server control unit 310 reads various setting information necessary for processing of the game executed on the user terminal 10 from the storage unit 35 in response to a request from the user terminal 10, and the user terminal via the communication unit 32. 10 to send. Moreover, if the server control part 310 acquires the play result information which shows the play result of the game transmitted from the user terminal 10, it will memorize | store the acquired play result information in the memory | storage part 35 as historical information of a user's game.

  Here, the game setting information and history information stored in the storage unit 35 will be described in detail. For example, the storage unit 35 includes a user data storage unit 351, a card master data storage unit 352, a possessed card data storage unit 353, and a lottery right data storage unit 354.

  The user data storage unit 351 stores user information of a user who plays a game on the user terminal 10. For example, in the user data storage unit 351, user information such as a user ID and a user name, a login history, and a user level whose value increases according to the progress of the game is stored in association with each other.

  The card master data storage unit 352 stores master data (card master data) of cards prepared in the game. FIG. 7 is a diagram illustrating a data example of card master data stored in the card master data storage unit 352. In the illustrated card master data, card information such as a card ID, model, card name, card image, rarity, attribute, and character parameter is set in association with each other.

  The card ID is identification information that can be identified for each type of card. For example, as card types, cards with different card names or cards with the same card name but different rarity are identified as different types of cards. The usage is classified according to the usage of the card in the game, and a character, weapon, armor, or the like is set as indicated by each card. The card name is the name of each card and is the name of a character, weapon, armor or the like. The card image is an image representing at least a part of the character (weapon, armor, etc.) aspects (appearance, shape, name, etc.) of each card, and is, for example, an illustration drawn on the card. The rarity is an index indicating the rarity of each card, and is divided into four levels of 1, 2, 3, 4 in order from the lowest to the highest, for example. Here, rarity 1 indicates a normal card, rarity 2 indicates a rare card, rarity 3 indicates an S rare card, and rarity 4 indicates an SR rare card. For example, the user is more likely to advance the battle advantageously by using a card with high rarity. The attribute is information indicating an attack that the character of the card indicating the character is good at. For example, the attribute is associated with any one of fire, water, and wood, which are superior to each other. For example, if a water character attacks a fire character, the water character can do a great deal of damage. If a water character attacks, a water character can do a great deal of damage. If you attack, you can do a lot of damage.

  The character parameter is information whose value varies with the progress of the game, and includes, for example, the HP, attack power, defense power, and the like of each card (character). Note that the value of the character parameter set in the card master data is an initial value when a card is given to the user. HP is a value representing the physical strength or vitality of each card (character). The attack power is information indicating the attack power in the battle of each card (character). Defense power is information which shows the value of defense power in the battle of each card (character). These character parameters are changed in the course of the game by winning or losing battles or combining cards (by increasing the value of character parameters by combining multiple cards into one card). For example, the battle can be advantageously advanced as the values of HP, attack power, defense power, and the like increase.

  The possession card data storage unit 353 stores possession card data for managing cards possessed by each user. For example, in the possessed card data, the user ID of the user, the serial number (serial number) of the card possessed by the user, the card ID, the character name, the character image, the rarity, and the character parameter are stored in association with each other. Is done. The serial number is a number uniquely assigned to each character card, and is information that can identify each character card in the game. Even if character cards with the same card ID are possessed, different serial numbers are associated with each other. The card ID, character name, character image, rarity, and character parameters store the master data value (card master data value) of the card when the card is given to the user. As the game progresses, the value of the character parameter of the possessed card data is updated as needed.

  The lottery right data storage unit 354 stores lottery right data related to the lottery right given to each user. For example, in the lottery right data, the user ID of the user and information regarding the lottery right granted to the user (for example, the lottery right acquired by the user with the login reward) are stored in association with each other. The information regarding the lottery right includes the type of the lottery target card, the lottery probability, and the like.

  Returning to FIG. 6, the functional configuration of the process related to the login reward executed by the server control unit 310 will be described. The server control unit 310 includes a login information acquisition unit 311, a lottery right presentation unit 312, a lottery right change unit 313, and a lottery right grant unit 314. The login information acquisition unit 311 acquires login notification information transmitted from the user terminal 10 via the communication unit 32.

  The lottery right presentation unit 312 is a lottery probability (for example, 10%) that a specific character card (for example, a rare card or more) that can be used in the game is drawn based on a predetermined condition based on a user operation being satisfied. ) Is set so that the user can acquire the lottery right. Here, the predetermined condition is a condition for giving a login reward, for example, a user logging in to a game. More specifically, the predetermined condition is, for example, logging in for the first time in one day. For example, the lottery right presentation unit 312 refers to the login history of the user data stored in the user data storage unit 351 based on the login notification information acquired by the login information acquisition unit 311 and determines whether or not a predetermined condition is satisfied. (Whether or not it is the first login within a day). When the lottery right presentation unit 312 determines that the predetermined condition is satisfied, the lottery right presentation unit 312 determines that the lottery right presentation unit 312 is a target of login reward, and transmits the login reward presentation information to the user terminal 10 via the communication unit 32. Thereby, in the user terminal 10, the lottery right (lottery ticket) based on the login reward presentation information is presented as the login reward. On the other hand, if the lottery right presentation unit 312 determines that the predetermined condition is not satisfied, the lottery right presentation unit 312 determines that the login reward is not targeted and does not transmit the login reward presentation information.

  The lottery right presentation unit 312 may present the lottery right (lottery ticket) so that the user can acquire it based on the fact that the predetermined condition is satisfied within a predetermined period. The predetermined period here is an event period in which a login reward is given, and is a period (for example, two weeks) set by a game provider, for example.

  When the lottery right changing unit 313 holds the lottery right presented as the login reward by the lottery right presenting unit 312 without acquiring it, the lottery right presenting unit 312 presents the lottery right presenting unit 312 based on the fact that the predetermined condition is satisfied next. The lottery probability set in the lottery right to be raised is increased. For example, the lottery right changing unit 313 increases the lottery probability of the next lottery right when information indicating that the user has suspended the lottery right without acquiring the lottery right is acquired from the user terminal 10 via the communication unit 32. For example, the lottery right changing unit 313 presents a lottery right (lottery ticket) in which the lottery probability is set to 10% in the first login reward, and when the lottery right is put on hold, the lottery probability is changed in the next login reward. A lottery right (lottery ticket) with a 5% rise and a lottery probability of 15% is presented. The timing for increasing the lottery probability may be the timing when the user holds the lottery right without acquiring the lottery right, the timing when the user presents it after the predetermined condition is satisfied, or the time between the holding and the next presentation. Any timing may be used.

  When the user acquires the lottery right (lottery ticket) presented as the login reward by the lottery right presenting unit 312, the lottery right granting unit 314 grants the lottery right to the user. For example, the lottery right granting unit 314 grants the lottery right to the user when acquiring information indicating that the user has acquired the lottery right from the user terminal 10 via the communication unit 32. Specifically, the lottery right granting unit 314 relates to the user's user ID and the lottery right (lottery right acquired by the user) to be given to the user in the lottery right data stored in the lottery right data storage unit 354. Store information in association with it. Thereby, the user can perform card lottery with the given lottery rights.

  For example, the server control unit 310 refers to the lottery right data stored in the lottery right data storage unit 354 in response to a request from the user terminal 10, and transmits information indicating the executable lottery right to the communication unit 32. It is presented to the user by being transmitted to the user terminal 10 via. When the user selects an executable lottery right and a card lottery execution request based on the selected lottery right is transmitted from the user terminal 10 to the game server 30, the server control unit 310 sets the selected lottery right. The card lottery is executed according to the set lottery conditions. Then, the server control unit 310 adds the character card data selected by the lottery to the possession card data stored in the possession card data storage unit 353 in association with the user ID, thereby selecting the character card selected by the lottery. Is given to the user.

[Operation of processing related to login reward]
Next, with reference to FIG. 8, the operation | movement of the login reward process which the game server 30 performs is demonstrated. FIG. 8 is a flowchart illustrating an example of the login reward process. When the user logs in to the game at the user terminal 10, the server control unit 310 of the game server 30 acquires the login notification information transmitted from the user terminal 10 via the communication unit 32 (step S100).

  Next, the server control unit 310 refers to the login history of user data stored in the user data storage unit 351 based on the acquired login notification information, and determines whether or not a predetermined condition is satisfied. Specifically, the server control unit 310 determines whether or not it is today's first login as a predetermined condition (step S102).

  In step S102, when it is determined that it is not the first login of today, that is, when it is determined that the predetermined condition is not satisfied (NO), the server control unit 310 determines that it is not a target of the login reward, The process ends. On the other hand, when it is determined that it is the first login of today, that is, when it is determined that a predetermined condition is satisfied (YES), the server control unit 310 determines that the login is a target of login reward and presents the login reward. Information is transmitted to the user terminal 10 via the communication unit 32. Thereby, the login reward screen (for example, the login reward screen G10 having a lottery probability of 10% in FIG. 1) on which the lottery right (lottery ticket) is presented is displayed on the user terminal 10 (step S104).

  Next, the server control unit 310 determines whether or not the user has acquired a lottery right on the login reward screen displayed on the user terminal 10 (step S106). Specifically, when the server control unit 310 acquires information indicating that the user has acquired the lottery right from the user terminal 10 via the communication unit 32, the server control unit 310 determines that the user has acquired the lottery right (YES) ). On the other hand, if the server control unit 310 acquires information indicating that the user has suspended without acquiring the lottery right from the user terminal 10 via the communication unit 32, the server control unit 310 determines that the user has suspended without acquiring the lottery right. (NO)

  If the server control unit 310 determines that the user has suspended without acquiring the lottery right (NO), the server control unit 310 determines whether the lottery probability has reached 100% (step S108). When it is determined that the lottery probability has not reached 100% (NO), the server control unit 310 increases the lottery probability (for example, 5% UP) and ends the process (step S110). Thereby, at the time of the next login reward, a login reward screen (for example, a login reward screen with a lottery probability of 15% in FIG. 2) on which the lottery right (lottery ticket) with an increased lottery probability is presented to the user terminal 10 is presented. G20) is displayed on the user terminal 10.

  On the other hand, if the user does not receive the lottery right and keeps holding for each login reward, the lottery probability further increases and reaches 100% after several days. If it is determined in step S108 that the lottery probability has reached 100% (YES), the server control unit 310 ends the process without changing the lottery probability. That is, when the lottery probability reaches 100%, the lottery probability remains at 100% even if the lottery right is suspended thereafter.

  If the server control unit 310 determines in step S106 that the user has acquired the lottery right (YES), the server control unit 310 grants the lottery right to the user (step S112). Specifically, the server control unit 310 adds the user ID of the user to the lottery right data stored in the lottery right data storage unit 354 and information on the lottery right (the lottery right acquired by the user) to be given to the user. Are stored in association with each other. Thereby, the user can perform card lottery with the given lottery rights. Subsequently, the server control unit 310 sets the lottery probability to an initial value (for example, 10%), and ends the process (step S114). That is, when the user acquires a lottery right with an increased lottery right, the next lottery probability returns to the initial value.

  In addition, when it becomes a continuous login by logging in on the next day when the user holds the lottery right based on the login reward, when the user further holds the lottery right with the increased lottery probability, the server control unit 310 increases the lottery probability to be increased. The rate of increase may be increased from the previous rate of increase. For example, the increase rate of the previous day was 5%, but the server control unit 310 may increase the increase rate further by 1% to 6% because the login is performed continuously on the next day. Further, when the user logs in the next day, the server control unit 310 may further increase the increase rate of the lottery probability after the suspension to 7%. In other words, the more you log in continuously, the higher the rate of increase. In this way, by increasing the rate of increase as the number of continuous logins increases, it is possible to give the user a stronger motivation for login in order to prevent the continuous login from being interrupted. If the continuous login is interrupted, the rate of increase may be restored to 5%.

  FIG. 9 is a diagram illustrating an example of the next login reward screen after continuously logging in and holding again on the next day after the suspension. In the illustrated login reward screen G30, the increase rate of the lottery probability is increased from 5% to 6% with respect to the lottery ticket (lottery right) presented on the login reward screen G20 of FIG. The login reward screen G30 includes information K31 indicating today's login reward and that the user has logged in for two consecutive days and that the lottery right of the lottery ticket has been increased (in this case, 6% UP); A lottery ticket K32 of a lottery right in which a card of a rare card or higher is drawn with a lottery probability of 21% is displayed. Also, information K33 is displayed below the lottery ticket K32 for notifying that if the lottery right is suspended and logging in tomorrow, the lottery probability will increase (up) by 7%. Further, the button B1 and the button B2 are displayed on the login reward screen G20 as in FIG. The user can select whether to obtain a lottery ticket (lottery right) with an increased lottery probability or to hold it without obtaining it.

[Summary of First Embodiment]
As described above, the game server 30 (an example of a game device) according to the present embodiment includes a lottery right presentation unit 312 (an example of a presentation unit) and a lottery right change unit 313. The lottery right presentation unit 312 has a lottery right in which a lottery probability that a character card (an example of a specific object) that can be used in the game is lottered is set based on a predetermined condition based on a user operation. Are presented so that the user can obtain them. If the user does not acquire the lottery right presented by the lottery right presenting unit 312, the lottery right changing unit 313 will next present the lottery right presented by the lottery right presenting unit 312 based on the predetermined condition being satisfied. Increase the lottery probability set to.

  As a result, the game server 30 provides the user with an option of whether the user acquires the lottery right or can acquire the lottery right that has increased the lottery probability next time without acquiring the lottery right. It is possible to respond to both the user's request to be performed and the user's request to perform the card lottery after raising the lottery probability. Therefore, according to the present embodiment, a reward that is beneficial to many users can be given.

  Here, the predetermined condition is, for example, that the user logs in to the game.

  Thereby, since the game server 30 can acquire the drawing right by logging in to the game, the user can be prompted to log in to the game, and the continuation rate at which the user continues to play the game can be improved. .

  In addition, said predetermined condition is not restricted to logging in to a game, Any action of the user with respect to a game may be sufficient. For example, the predetermined condition may be to defeat the enemy in the game or to send a comment or mail in the game.

  For example, the lottery right presentation unit 312 limits the number of times that the lottery right is presented on one day (an example within a predetermined first period) to one (an example of the predetermined number of times).

  Accordingly, the game server 30 is limited to a maximum of once per day (for example, when logging in for the first time in a day), and a lottery right is presented as a login reward to a user who logs in to the game. The user can be prompted to log in every day, and the continuation rate at which the user continues to play the game can be improved.

  In this embodiment, the lottery right is presented as a login reward up to once per day, but is not limited to one day. For example, it may be several days or several hours. It is good also as a unit.

  In addition, it is desirable that there is a limit to the period during which the login reward is given. For example, the lottery right presentation unit 312 presents the lottery right based on the fact that a predetermined condition is satisfied during an event period (an example within a predetermined second period) in which a login reward is given.

  Thereby, the game server 30 can raise the necessity for login more with respect to a user, when a login reward has a time limit. For example, the game server 30 can give the user a special feeling only during the event period, and can prompt the user who usually plays less frequently to log in to the game.

  In addition, the lottery right changing unit 313 may change the rate of increase of the lottery probability to be increased next based on the predetermined condition being satisfied, depending on the situation where the predetermined condition is satisfied.

  Thereby, the game server 30 can increase or decrease the increase rate of the lottery probability depending on, for example, a situation where a predetermined condition is satisfied. For example, when the predetermined condition is to defeat the enemy in the game or to send a comment or email in the game, the game server 30 increases the rate of increase of the lottery probability depending on the condition that the condition is satisfied. The user can be motivated to play by playing the game so that the rate of increase in the lottery probability increases. In addition, when the predetermined condition is not to defeat the enemy in the game or not to send a comment or an e-mail in the game, the game server 30 reduces the increase rate of the lottery probability depending on the condition that the condition is satisfied. And the motivation to play to play a game can be given to a user so that the increase rate of a lottery probability may not decrease.

  In addition, the lottery right changing unit 313 increases the rate of increase of the lottery probability to be raised next when the predetermined condition is satisfied when the predetermined condition is continuously satisfied in a predetermined unit.

  For example, the game server 30 can increase the increase rate of the lottery probability as the user continuously logs in a predetermined unit (for example, every day). In this case, the game server 30 can strongly give the user the motivation to log in to log in so that the continuous login is not interrupted.

  Note that the situation in which the predetermined condition is satisfied is not limited to continuous login, and may be the number of logins within a predetermined period (for example, one day), for example.

  In addition, when the user acquires the lottery right presented by the lottery right presenting unit 312, the lottery right changing unit 313 next draws the lottery right presented by the lottery right presenting unit 312 based on a predetermined condition being satisfied. The lottery probability set in is set to the initial value.

  Thereby, when the user acquires the lottery right whose lottery probability has increased by the user holding the lottery right, the game server 30 returns the lottery right to the original initial value from the next lottery. Thus, it is possible to prevent the character card from being given too much.

  The character card (an example of a specific object) is an object associated with a specific parameter. Here, the specific parameter is a parameter indicating the rarity of the character card.

  Thereby, the game server 30 acquires the lottery right that the lottery probability is increased without the user acquiring or acquiring the character card lottery right associated with a specific parameter (for example, rarity or the like). The user can be provided with the choice of whether to enable. Therefore, the game server 30 can respond to both the user's desire to perform the card lottery and the user's request to perform the card lottery after raising the lottery probability. Therefore, according to the present embodiment, a reward that is beneficial to many users can be given.

  The specific parameter is not limited to rarity but may be another parameter associated with the character card. The specific parameter may include other parameters in addition to the rarity. The other parameters may be, for example, character card attributes, HP, attack power, defense power, and the like.

  The lottery right is a lottery ticket (an example of an item) used in the game. Thereby, since the game server 30 explicitly grants a lottery right that can be used in the game, the user can be motivated to play the game.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Since the configuration of the game system 1 of the present embodiment is the same as that of the first embodiment, characteristic processing in the present embodiment will be described. In the present embodiment, when the lottery probability reaches 100%, when the user holds the lottery without acquiring the lottery right, an example in which the rarity of the character card to be a lottery with the lottery right by the next login reward is increased will be described. To do.

  For example, when the user does not acquire the lottery right presented by the lottery right presenting unit 312, the lottery right changing unit 133 is based on the fact that a predetermined condition (a condition for providing a login reward) is satisfied next. , Raise the rarity of the character card to be selected. For example, as described in the first embodiment, if the user keeps holding without receiving the lottery right, the lottery probability reaches 100%. In this case, the lottery right changing unit 133 increases the rarity of the character card that is a lottery target in the next day login reward. For example, the lottery right changing unit 133 changes the rare card to an S rare card having a higher rarity than the rare card.

  FIG. 10 is a diagram illustrating an example of a login reward screen when the lottery probability reaches 100%. The illustrated login reward screen G40 includes information indicating that the login reward is today's login reward and that the user is currently logged in consecutively on the ○ day, and that the lottery right of the lottery ticket has been increased (○% UP). K41 and a lottery ticket K42 of a lottery right for drawing a card of rare card or higher with a lottery probability of 100% are displayed. Also, below the lottery ticket K42, when the probability of drawing more than this rare card has reached 100%, and if you hold this lottery right and log in tomorrow, more than S rare cards with higher rarity than the rare card will be drawn. Information K43 for notifying that it is a target (the lottery probability is 10%) is displayed. Because the rarity has increased, the lottery probability has returned to the initial value. In addition, a button B1 and a button B2 are displayed on the login reward screen G40. The user can select whether to acquire the lottery ticket K42 (lottery right) or to hold it without acquiring it.

  FIG. 11 is a diagram showing an example of a login reward screen on which a lottery right with increased rarity is presented, and is an example displayed as the next login reward screen after the lottery right shown in FIG. 10 is suspended. In the login reward screen G50 shown in the figure, information indicating that the login reward is today's login reward and that the user is currently logged in for consecutive days, and that the grade of the lottery rights based on the lottery ticket is UP (in this case, the rarity is increased). K51 and a lottery ticket K52 of a lottery right in which cards of S rare cards or higher are drawn with a lottery probability of 10% are displayed. Because the rarity has increased, the lottery probability has returned to the initial value. Also, information K53 is displayed below the lottery ticket K52 for notifying that if the lottery right is held and logging in tomorrow, the lottery probability will increase by 3% (UP). In addition, the increase rate of the lottery probability when logging in the next day is 3%, which is lower than the increase rate of the lottery right over the rare card. By changing the rate of increase of the lottery probability depending on the rarity, the card grant balance in the game is maintained so that a high rarity card or the like is not given too much in the lottery. For example, the higher the rarity, the lower the rate of increase of the lottery probability. Further, a button B1 and a button B2 are displayed on the login reward screen G50. The user can select whether to acquire the lottery ticket K52 (lottery right) or to hold it without acquiring it.

  FIG. 12 is a diagram showing an example of a login reward screen displayed when the user acquires the lottery right shown in FIG. When the user operates the button B1 on the login reward screen G50 shown in FIG. 11, the user possesses the lottery right of the lottery ticket K52 presented on the login reward screen G50. The login reward screen G60 shown in FIG. 12 displays information K61 indicating that the user has received a lottery ticket (lottery right) in which a card of S rare card or higher is drawn with a lottery probability of 10%. When the user acquires a lottery ticket (lottery right), a new lottery ticket is set. On the login reward screen G60, a newly set lottery ticket K62 (rare card or higher, lottery probability 10%) and information K63 indicating that the lottery ticket K62 will be presented (to be a login reward) by tomorrow's login Is displayed. The newly set lottery ticket K62 is also held in the same manner as described above, whereby the lottery probability and the rarity can be increased for each login reward.

  Next, with reference to FIG. 13, the operation of the login reward process according to the present embodiment will be described. FIG. 13 is a flowchart illustrating an example of the login reward process according to the present embodiment. The login reward process shown in FIG. 8 is different from the login reward process of the first embodiment shown in FIG. 8 in that the processes of steps S200, S201, and S202 are added, and the process when the lottery probability reaches 100% is different. . In this figure, processes corresponding to the processes in FIG. 8 are denoted by the same reference numerals, and description thereof is omitted.

  When it is determined in step S108 that the lottery probability has reached 100% (YES), the server control unit 310 increases the rarity (for example, UP from a rare card or more to an S rare card or more) (step S200). Subsequently, the server control unit 310 sets the lottery probability to an initial value (for example, 10%), and ends the process (step S201). That is, when the rarity of the next lottery right increases due to the user holding the lottery right, the lottery probability returns to the initial value.

  When it is determined in step S106 that the lottery right has been acquired, the server control unit 310 gives the lottery right to the user (step S112). Then, the server control unit 310 sets the lottery probability to an initial value (for example, 10%) (step S114), sets the rarity to an initial value (for example, a rare card or more) (step S202), and ends the process. To do. That is, as described in the first embodiment, when the user acquires a lottery right with an increased lottery probability, the next lottery probability returns to the initial value, and in the present embodiment, the lottery with increased rarity. When the user acquires the right, the next rarity returns to the initial value.

[Summary of Second Embodiment]
As described above, the lottery right changing unit 313 of the game server 30 (an example of a game device) according to the present embodiment, when the user does not acquire the lottery right presented by the lottery right presenting unit 312, Raise the rarity (an example of a specific parameter) of a character card (an example of a specific object) that is drawn according to the lottery probability based on the fact that a condition for giving a login reward (an example of a predetermined condition) is satisfied.

  As a result, the game server 30 responds to both the user's desire to perform a card lottery for a character card with low rarity for each login reward, and the user's request to perform a card lottery after raising the rarity to a high level. Can do. For example, beginner users tend to prefer numbers over high-value ones because they do not have cards or the like. In this case, by receiving lottery rights at an early stage, it is possible to arrange the numbers even if the rarity is low. On the other hand, an advanced user who has a certain number of necessary cards tends to desire one more necessary than the number. In such a case, it is possible to easily obtain a desired card by increasing the rarity and the lottery probability. According to the present embodiment, selection according to the user's request can be made at the user's discretion for each user. Therefore, a reward that is beneficial to many users can be given.

  Note that the lottery right changing unit 313 may decrease the increase rate of the lottery probability as the rarity of the character card (an example of a specific object) is higher.

  Thereby, the game server 30 can prevent the character card of high rarity from being drawn too much, and can maintain the grant balance of the character card in the game.

  Note that raising the lottery probability when it reaches 100% is not limited to rarity, but may be another parameter. For example, when the lottery probability reaches 100%, the game server 30 may increase other parameters such as attack power and defense power.

[Modification]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and includes a design and the like within a scope not departing from the gist of the present invention. For example, the configurations described in the first and second embodiments can be arbitrarily combined.

  In the above embodiment, an example has been described in which, when continuous login is interrupted, the rate of increase in the lottery probability is returned to the initial value, but the process when the login is interrupted is not limited thereto. For example, the game server 30 may not return the increase rate of the lottery probability to the initial value when the continuous login is interrupted. In this case, the rate of increase only increases when logging in continuously, and does not decrease. Further, instead of returning to the initial value, it may be close to the initial value. In addition, when there is a day when the user does not log in, the game server 30 may reduce the increase rate of the lottery probability according to the number of days. In short, when the user does not log in for one day, the increase rate of the lottery probability may be gradually decreased instead of returning to the initial value all at once.

  Moreover, in the said embodiment, when the lottery ticket (lottery right) was acquired, the lottery ticket was once possessed, and the example which can perform card lottery by using it was demonstrated, but a lottery ticket (lottery right) Card lottery may be executed by acquiring a lottery ticket (lottery right) instead of possessing it by acquiring.

  Further, the increase rate of the lottery probability may be increased greatly on a specific day. For example, on the day of the week when the in rate becomes worse, the increase rate of the lottery probability may be set higher.

  In the above embodiment, the lottery ticket as a single login reward has a lottery right for one card lottery, but the lottery right is not limited to one card lottery. A lottery right for any number of two or more cards may be set. Further, a lottery right for a plurality of times may be set in a lottery ticket as a single login reward. When lottery of a plurality of cards or lottery rights for a plurality of card lotteries are set for one login reward, a plurality of rarities (an example of specific parameters) or lottery probabilities may be set. For example, it may be a lottery right in which two types of card lottery are set such that a rare card or higher is a lottery probability of 50% and an S rare card or higher is a lottery probability of 10%.

  In the above embodiment, the storage unit 35 of the game server 30 includes the user data storage unit 351, the card master data storage unit 352, the possessed card data storage unit 353, and the lottery right data storage unit 354. Although the configuration has been described, a part of each storage unit included in the storage unit 35 or a part of data stored in each storage unit may be stored in the storage unit 15 of the user terminal 10. For example, each user's data (for example, each user's user data and possession card data) among the data memorize | stored in the memory | storage part 35 may be memorize | stored in each memory | storage part 15 of the user terminal 10 of each user. . That is, the game server 30 may store data of all users registered in the game, and the user terminal 10 may store data of each user. In this case, the data stored in the game server 30 and the data stored in the user terminal 10 are synchronized at a predetermined opportunity.

  Further, a program for realizing the functions of the above-described game control unit 110 or server control unit 310 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. As a result, processing as the game control unit 110 or the server control unit 310 may be performed. Here, “loading and executing a program recorded on a recording medium into a computer system” includes installing the program in the computer system. The “computer system” here includes an OS and hardware such as peripheral devices. Further, the “computer system” may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, and dedicated line. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. As described above, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside that is accessible from the distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program that can be executed by the terminal device. That is, the format stored in the distribution server is not limited as long as it can be downloaded from the distribution server and installed in a form that can be executed by the terminal device. Note that the program may be divided into a plurality of parts, downloaded at different timings, and combined in the terminal device, or the distribution server that distributes each of the divided programs may be different. Furthermore, a “computer-readable recording medium” holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or client when the program is transmitted via a network. Including things. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.

  Further, some or all of the functions of the game control unit 110 or the server control unit 310 described above may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each function described above may be individually made into a processor, or a part or all of them may be integrated into a processor. Further, the method of circuit integration is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. In addition, when an integrated circuit technology that replaces LSI appears due to the advancement of semiconductor technology, an integrated circuit based on the technology may be used.

  Moreover, although the game server 30 demonstrated the structure which performs the process regarding a lottery in the said embodiment, it is good also as a structure where the user terminal 10 performs the process regarding a lottery. For example, when the game process executed on the user terminal 10 is performed independently (stand-alone) on the user terminal 10, the functional configuration for performing the process related to the lottery on the user terminal 10 has been described in the above embodiment. The lottery right presentation unit 312, the lottery right change unit 313, the lottery right grant unit 314, the user data storage unit 351, the card master data storage unit 352, the possessed card data storage unit 353, the lottery right data storage unit 354, and the like. The user terminal 10 may be provided.
