Having. For example, the extinguishing unit 420 may erase the privilege when the lottery according to the changed lottery condition is performed once, or may erase the privilege when performing the lottery according to the changed lottery condition a predetermined number of times. good. Further, the extinguishing unit 420 may be configured to extinguish the privilege after a predetermined period has elapsed, regardless of whether or not the lottery is performed based on the changed lottery conditions. Providing the disappearance unit 420 makes it easier to prevent an excessive difference between a player who has charged and a player who has not charged.

  The holding unit 421 has a function of holding a privilege not used for changing the lottery condition. As the privilege held by the holding unit 421, for example, a privilege corresponding to an increase / decrease value exceeding an upper limit of an increase / decrease value of the lottery probability of an object, a privilege not used for changing a lottery condition by a player's selection, or the like is used. No. It is preferable that the privilege held by the holding unit 421 be configured to be used for changing the lottery conditions after the next time. It is preferable that an image corresponding to the privilege held by the holding unit 421 be displayed on the display unit. With such a configuration, for example, it is possible to ask the player to determine whether or not to change the lottery conditions using the privilege, and it is possible to enhance the interest of the game.

  The restriction unit 422 has a function of restricting the lottery of the object based on the lottery condition changed by the change unit 417 within a predetermined period and / or a predetermined number of times. Here, “within a predetermined period” can be appropriately set according to the game mode, for example, within a specific event period or between 1st and 10th every month. Further, “within a predetermined number of times” can be appropriately set according to the mode of the game, for example, once or less, or less than ten times. The restriction unit 422 can also restrict the lottery of the object based on the changed lottery condition, for example, to “up to ten times within a specific event period”. With such a configuration, it is easy to prevent an excessive difference from occurring in the game between the player who has paid and the player who has not paid. Further, it is easy to prevent the player from being excessively charged for the purpose of changing the lottery conditions.

  On the other hand, the restriction unit 422 may change the content of the restriction according to the charge amount of the player. For example, for a player whose billing amount is larger than a predetermined amount, the number of times that the object can be drawn based on the changed lottery condition is set more than for a player whose charging amount is smaller than the predetermined amount. You may. With such a configuration, it is possible to reduce the possibility that a player who has many benefits due to a large billing amount cannot use up the benefits.

  Hereinafter, as an example of the game, a role playing game in which the game is advanced using objects owned by the player (usable by the player) will be described. The genre of the game is not limited to the role playing game, but can be applied to any genre such as a simulation game and an action game.

  In the object, parameters (for example, offensive power, defensive power, maximum hit points, etc.) used in the game, skills having a predetermined effect, and the like are set. The player selects an arbitrary object from the possessed objects and, for example, performs a virtual battle with an enemy character or another player. Winning or losing in the virtual battle is determined based on parameters, skills, and the like set for the object. In addition, the object is set to a rare level. It is preferable that the higher the rarity is, the higher the rarity in the game is, and the lower the winning probability at the time of executing the lottery is set. Further, it is preferable that the parameter used in the game is set higher for an object with a high rarity than for an object with a low rarity.

  When the player has charged, a virtual currency or the like in an amount corresponding to the charged amount is provided to the player. The player can draw objects by consuming virtual currency or the like, and the drawn objects are given to the player. In addition, when the player charges, a correction value (increase / decrease value) capable of increasing or decreasing the lottery probability of the predetermined object is provided to the player as a benefit by charging, separately from the virtual currency and the like. Granted. The correction value and the object information owned by the player are managed by the server device or the player terminal as, for example, player information. When the correction value or the object is given to the player, the information of the correction value or the object to be given is , The player information is updated so as to be included in the player information.

  First, the player terminal receives an operation input such as a button press or a touch panel operation by the player (step S31). When the player terminal receives an operation input for requesting charging, such as a touch input of a “purchase” button for purchasing virtual currency or the like displayed on the touch panel (step S32), information on the charging request of the player is displayed. Is transmitted from the player terminal to the server device (step S33). The information on the charging request of the player includes player information such as a player ID and information on a charging amount selected by the player.

  The server device receives information on the charging request of the player from the player terminal (step S34), and performs a process of charging the player with the charging amount selected by the player (step S35). Upon completion of the billing process, the server device grants the player a virtual currency or the like according to the billing amount to the player, and grants a virtual currency or the like and a correction value according to the billing amount of the player to the player as a privilege. (Step S36).

  FIG. 12 is an example of a display screen for accepting a billing request, corresponding to at least one of the embodiments of the present invention. The charging column 501 includes an image 502, a product name 503, a privilege 504, a charging amount 505, and a purchase button 506, and displays information such as a sales item and a charging amount. The image 502 is a column for displaying an image of an item to be sold or the like. For example, an image of a crystal is displayed in the image 502a. Here, the crystal is a kind of virtual currency given to the player by charging or the progress of the game, and is an item necessary for performing a lottery of objects.

  The sale item name 503 displays information such as names of items and points to be sold and quantities thereof. In the sale item name 503a, "120 crystals" is displayed, which indicates that 120 crystals are sold. In the sale item name 503b, “840 crystals + 160 (bonus)” is displayed, which means that 840 crystals are sold, and 160 crystals are added as a bonus when purchased. It indicates that it is further given to the player.

  The privilege 504 is for displaying a privilege that can be changed for the lottery condition of the object, which is given to the player when purchasing the product displayed in the sale item name 503. The benefit 504a displays "☆ 5 winning probability + 0.1% (limited to once a day)". Here, “☆ 5” indicates the rarity of the object. In the present embodiment, “☆ 5” has the highest rarity, and the rarity decreases as the number after ☆ decreases. It is assumed that "* 1" has the lowest rarity. Privilege 504a is a bonus in the case where a correction value that can increase the winning probability of an object whose rarity is set to “☆ 5” by “+ 0.1%” to the original winning probability is purchased (charged). It is shown that it is given to the player.

  The correction value is not limited to the one that increases the winning probability of “☆ 5”. For example, the correction value may be the one that increases the winning probability of “☆ 4” or the winning probability of an object with a low rarity such as “☆ 1”. It may be a reduction. If the winning probability of “☆ 5” is increased, the winning probability of any object other than “☆ 5” will decrease. However, from the viewpoint of increasing the satisfaction of the player who has paid, the lottery is performed. It is preferable to reduce the winning probability of the object having the lowest rarity among the target objects.

  In the example of FIG. 12, the correction value is given to the player separately from the crystal, and the crystal and the correction value can be used separately. With such a configuration, for example, even when a lottery is performed using a crystal obtained by achievement of an event, the correction value can be used, and the satisfaction of the player can be improved. On the other hand, a correction value and a crystal may be associated with each other and given to the player. For example, the correction value may be reflected only when a lottery is performed using a crystal purchased by charging. With such a configuration, it is possible to promote the motivation of the player to charge. It should be noted that the crystal obtained by charging may be distinguished from the crystal obtained by accomplishing the event. In this case, the storage unit stores the paid crystal and the free crystal in association with the player.

  In the privilege 504a, “limited to once a day” means that the correction value is given when the item displayed in the sale item name 503a is purchased within one day (for example, 00:00 to 23:59). This indicates that the benefit 504a is granted only once. For example, even if the purchase procedure for the sale item name 503a is performed a plurality of times during one day, the privilege 504a is granted only once, and Again, this shows that the privilege 504a can be given only once. In the example of FIG. 12, the grant is set to “limited once a day”. However, the present invention is not limited to this example. For example, “up to 10 times a week”, “5 times within a predetermined event period” A predetermined period and a predetermined number of times can be set as appropriate, such as "until the number of times". With such a configuration, it is possible to suppress excessive charging by the player, and it is easy to balance with other benefits.

  The benefit 504c displays "☆ 5 winning probability + 1.2%, population change item × 1", which means that the winning probability of the object whose rare degree is set to "☆ 5" is the original winning probability. A correction value that can change the probability to “+ 1.2%” and one item that can change the population of objects to be drawn are purchased (charged) for the item displayed in the sale item name 503c. It is shown that it is given as a privilege in the case. In addition, for example, as shown in FIG. 14 described below, when the increase value of the ☆ 5 winning probability has an upper limit of “+ 1.0%”, a correction value of “+ 1.2%” is given. However, the correction value that can be used in one lottery is up to “+ 1.0%”, and the remaining correction value of “0.2%” can be used in the subsequent lottery. In other words, the remaining correction value of “0.2%” is held by the holding unit 421.

  Items that can change the population of objects to be drawn are not particularly limited. For example, if an attribute such as "warrior" or "witch" is set for an object, only "warrior" is drawn. Items that can change the population of objects so as to be targeted, that is, so that “warrior” always wins, may be mentioned.

  The billing amount 505 indicates the amount necessary to purchase the item or the like displayed in the sale item name 503. "$ 120" is displayed in the charge amount 505a. This means that in order to purchase (acquire) 120 "crystals" displayed in the sale item name 503a, "$ 120" is charged. Indicates that is required. The purchase button 506 is a button for purchasing the item or the like displayed in the sale item name 503. When the purchase button 506 is selected by the player's touch operation or the like, the amount displayed in the billing amount 505 is charged to the player, and the item displayed in the sale item name 503 and the privilege displayed in the privilege 504 are displayed. Is given to the player.

  FIG. 13 is an example of a correspondence data table indicating object statuses and lottery probabilities corresponding to at least one of the embodiments of the present invention. The correspondence data table 511 stores, in association with the object ID 512, the rarity 513 of the object, the attack power 514 of the object, the defensive power 515 of the object, the winning probability 516 of the object, and the total winning probability 517 for each rarity. I have. The correspondence data table 511 may be read from any of the storage unit 13, the storage unit 33, and the external memory.

  The object corresponding to “5001” of the object ID 512 has the rarity 513 of “☆ 5”, the attack power 514 of “3000”, the defensive power 515 of “2500”, and the object winning probability 516 of “0.1%”. , Are each set. The attack power 514 and the defensive power 515 are examples of parameters set for the object, and are not limited to these. The winning probability total 517 is the sum of the winning probabilities for each rare degree. "1.0%" is described in the winning probability total 517a, which is the sum of the winning probabilities of all the objects for which the degree of rarity is set to "* 5".

  For example, when a lottery is performed using a correction value of “☆ 5 winning probability + 1.0%”, the rarity is set to “☆ 5” so that the total winning probability 517a becomes “2.0%”. A uniform value may be added to the winning probability of each object, or the winning probability of a specific object may be increased. When the winning probability of a specific object is to be increased, for example, a selection of a player may be used to determine which object to increase the winning probability.

  Further, for example, when a lottery is performed using the correction value of “☆ 4 winning probability + 3.0%”, the rare degree is set to “☆ 4” so that the winning probability total 517b is “12.0%”. The winning probability of at least one or more set objects is changed. In this case, the winning probability of any object other than “☆ 4” will decrease. However, it is preferable to reduce the total winning probability of objects having a rarity of less than “☆ 4”. It is more preferable to reduce the total winning probability of the object having the lowest rarity (for example, “☆ 1”). As described above, by changing the winning probability of each object so as to be advantageous to the player, the satisfaction of the charged player can be increased.

  Returning to the description of the flowchart of FIG. The server device transmits information on the correction value currently owned by the player to the player terminal based on the result of the correction value providing process in step S36 (step S37). Next, the player terminal receives the information (Step S38). The player terminal displays the correction value currently owned by the player on the display screen based on the received information in a manner recognizable by the player (step S39). Next, the player terminal receives a request from the player to perform a lottery of an object using the correction value, based on an operation input such as a button press or a touch panel operation by the player (step S40). Then, the player terminal transmits information on the accepted lottery of the object to the server device (Step S41).

  FIG. 14 is an example of a display screen that displays a correction value possessed by a player, corresponding to at least one of the embodiments of the present invention. On the display screen of the player terminal, a display area 521, a stock value 522, an increase / decrease button 523, and a lottery button 524 are displayed.

  The display area 521 is an area indicating a correction value used for the lottery. The hatched portion 521a in the display area indicates the correction value used for the lottery, and in the example of FIG. 14, the correction value used for the lottery is “+ 0.6%”. From the viewpoint that the correction value used for the lottery can be intuitively and easily grasped, the display area 521 preferably has a scale, and for example, is preferably a bar or a gauge having a scale.

  The stock value 522 indicates a correction value that is stocked without being used for the lottery. The stocked correction values can be used in subsequent lotteries. The increase / decrease button 523 is a button for increasing / decreasing the correction value used for the lottery. The player can reduce the correction value used for the lottery by performing a touch operation or the like on the increase / decrease button 523a. Further, the player can increase the correction value used for the lottery by performing a touch operation or the like on the increase / decrease button 523b. For example, in FIG. 14, when the player touches 523a, the correction value indicated by the hatched portion 521a in the display area becomes “0.5%”, and decreases according to the number of touch operations or the touch time of the player. To go.

  When the correction value indicated by the display area 521 decreases by operating the increase / decrease button 523a, the correction value corresponding to the decrease is added to the stock value 522. In addition, when the correction value indicated by the display area 521 increases by operating the increase / decrease button 523b, the correction value corresponding to the increase is subtracted from the stock value 522. With such a configuration, the player can determine the timing of using the correction value and the amount of the correction value, and can improve the satisfaction with the game. In the example of FIG. 14, the upper limit of the scale attached to the display area 521 is “+ 1.0%”, which means that the upper limit of the correction value that can be used in one lottery is “1.0”. % ".

  The lottery button 524 is a button for executing a lottery using the correction value indicated by the display area 521. The lottery buttons 524a to 524c have different numbers of lotteries and / or different values for the lottery. The lottery button 524a is a button for paying 300 crystals and performing one lottery of the object. The lottery button 524b is a button for paying 3000 crystals and executing an object lottery 11 times. The lottery button 524c is a button for paying one lottery ticket and executing one lottery of the object. Here, the lottery ticket is an item that is given to the player according to the progress of the game or the achievement of the event, and is an item that is not given by charging.

  In the example of FIG. 14, when an operation of selecting one of the lottery buttons 524a to 524c is performed, the correction value “+ 0.6%” is added to the originally set “☆ 5 winning probability”, and the object is set. Is executed. When the lottery button 524b is selected, the lottery may be performed by adding the correction value “+ 0.6%” to “☆ 5 winning probability” only in the first lottery, or in all of the eleventh lottery. In the above, the lottery may be performed with the correction value added, but from the viewpoint of improving the satisfaction of the player, it is preferable to perform the lottery with the correction value added in all of the 11 lotteries.

  Returning to the description of the flowchart of FIG. The server device receives information on the lottery of the object from the player terminal (Step S42). The information includes at least information for specifying the player, information on the correction value used for the lottery, and information on the number of lotteries (for example, one lottery or 11 consecutive lotteries).

  Next, the server device refers to the player information and determines whether or not the player who has requested the lottery satisfies a predetermined limit (step S43). Here, the predetermined restriction is to limit the change of the lottery probability using the correction value within, for example, a predetermined period and / or a predetermined number of times. For example, when the restriction "limited to three times a day" is provided, the correction value cannot be used more than three times a day. If it is determined that the player who has requested the lottery does not satisfy the predetermined limit (No in step S43), an error is displayed on the display screen of the player terminal, and the process returns to step S40.

  If it is determined that the player who has requested the lottery satisfies the predetermined limit (Yes in step S43), the object to be changed is determined based on the information regarding the correction value used in the lottery received in step S42. Is changed (step S44). Next, the server device subtracts the correction value used for changing the winning probability from the correction value possessed by the player (Step S45). Next, the server device performs a lottery of the object based on the winning probability changed in the step S44 (step S46), gives the object won by the lottery to the player (step S47), and ends.

  In the sixth embodiment, “player terminal”, “player”, “server device”, “game”, “object”, “lottery condition”, “billing”, “privilege”, and “grant” are respectively The contents described in the first embodiment can be adopted within a necessary range. In the sixth embodiment, “change privilege” and “increase / decrease lottery probability” can employ the contents described in the second embodiment within a necessary range. Further, in the sixth embodiment, the content described in the third embodiment can be adopted as the “object attribute” within a necessary range. Further, in the sixth embodiment, “accept billing” can adopt the contents described in the fourth embodiment to the necessary range.

  As one aspect of the sixth embodiment, by giving a privilege that can change the lottery condition of the object in accordance with the charging of the player, for example, the winning probability of an object with a high rarity is increased by charging, etc. Thus, the player can perform a lottery under conditions more advantageous than the originally set lottery conditions, and the satisfaction of the charged player can be increased.

  As one aspect of the sixth embodiment, the content of a privilege (for example, a correction value) to be given to a player is changed according to the charge amount of the player, and the lottery probability of an object is increased or decreased according to the content of the privilege. Thereby, for example, a player who has a large charge can greatly increase or decrease the lottery probability of the object, and can increase the satisfaction of a player who has a large charge. Further, it is possible to promote the motivation of the player to charge.

  As one aspect of the sixth embodiment, for example, by increasing or decreasing the lottery probability of an object having a predetermined attribute in accordance with a charge of a player, for example, an object with a high degree of rarity can easily win the charged player. State, and the satisfaction of the charged player can be increased.

  As one aspect of the sixth embodiment, by providing a predetermined upper limit to the correction value used to change the lottery probability of an object, an excessive difference between a player who has paid and a player who has not paid in the game. Is easily prevented from occurring. In addition, for example, it is easy to prevent the player from being excessively charged, such as charging until the lottery probability of a predetermined object can be set to 100%.

  As one aspect of the sixth embodiment, the correction value corresponding to the excess when the correction value exceeds a predetermined upper limit can be held as stock, so that the stocked correction value can be used for the next and subsequent lottery conditions. It can be used for the change, and for example, it is possible to prevent the player from feeling dissatisfied because the excess of the upper limit disappears without being used for changing the lottery condition.

  As an aspect of the sixth embodiment, the correction value used for changing the lottery probability is displayed on the player terminal using the display area having the scale, so that the player can intuitively display the correction value used for the lottery. And it becomes possible to grasp easily.

  As one aspect of the sixth embodiment, by restricting the lottery of the object based on the changed lottery condition within a predetermined period and / or a predetermined number of times, the player who has charged in the game can It is easy to prevent an excessive difference from occurring between players who do not charge. Further, it is easy to prevent the player from being excessively charged for the purpose of changing the lottery conditions.

  As one aspect of the sixth embodiment, when an object is drawn based on the changed lottery condition, by extinguishing the privilege used for changing the lottery condition, a player who has made a charge and a player who has not made a charge It is easy to prevent an excessive disparity from occurring. In addition, if the configuration is such that the privilege is not extinguished, it is difficult to grant a privilege that greatly changes the lottery conditions in order to maintain the game balance, but with the above configuration, it is a privilege that greatly changes the lottery conditions. However, it is easy to provide the game, and as a result, the satisfaction of the player can be improved.

  As one aspect of the sixth embodiment, by allowing the player to select whether or not to change the lottery condition using the benefit and by enabling the unused benefit to be stocked, the lottery condition using the benefit can be used. Can be requested from the player as to whether or not to make a change, and the strategic nature of the game can be enhanced. In addition, it is possible to provide the player with a pleasure of accumulating benefits, and to enhance the interest of the game.

  As one aspect of the sixth embodiment, it is possible to select the quantity and / or type of the privilege used for changing the lottery condition by the player, so that the request for changing the lottery condition is different for each player. Also, the satisfaction of each player can be increased.

  As one aspect of the sixth embodiment, by making it possible to change the population of objects to be drawn in accordance with the charge, it is possible to widely cover the demands of the player who made the charge for the lottery, It is possible to increase the degree of satisfaction of the player who made the game.
