<Functional Configuration of Control Unit 20 of Server Device 2>
As shown in FIG. 1, the control unit 20 of the server device 2 functions as a collation unit 201, a normal lottery execution unit 202, a special lottery execution unit 203, and a communication unit 204 by executing the computer program of the present invention.

<Description of Matching Means 201>
The matching unit 201 authenticates a user account using the user identification information transmitted from the game device 3.

<Description of the normal lottery execution means 202>
The normal lottery executing means 202 executes the normal gacha upon receiving the later-described normal gacha request information from the game apparatus 3 via the communication means 204.

  Specifically, the normal lottery execution means 202 selects a character from the normal gacha list, and generates information on the selected character. The information on the character is associated with the user identification information.

  When the user requests a normal gacha (when “Gacharu!” In FIG. 2 is touched), the normal lottery execution means 202 selects one character by one gacha request by the user. .

  The normal lottery execution means 202 stores information on the character associated with the user identification information in the storage unit 21 and transmits the information to the game device 3 via the communication means 203.

<Description of the special lottery execution means 203>
The special lottery executing means 203 refers to the storage unit 21 and counts the number of times when characters having the same rarity are continuously selected by the normal gacha.

  Then, the special lottery executing means 203 executes an additional lottery when a character having the same rarity is continuously selected by the normal gacha for a first predetermined number of times or more. In the following, an example is described in which characters with a normal rarity are continuously selected by a normal gacha. However, this is not the only case. The present invention is also applied to the case where the selection is continuously performed a predetermined number of times or more.

  Here, the additional lottery is a lottery of whether or not the right to execute a special gacha for selecting a character from a special gacha list in which a plurality of types of characters are stored is associated with the user identification information (given to the user). .

  For example, the special lottery executing means 203 executes an additional lottery when a normal character is continuously selected three or more times by a normal gacha.

  Also, when the special lottery execution means 203 wins the additional lottery, the right to execute the special gacha is associated with the user identification information. In the present embodiment, this right is reserved until the user requests the special gacha and does not disappear (the association with the user's identification information is not released).

  Further, the special lottery executing means 203 increases the probability of winning an additional lottery as the number of times that characters of the same rarity are continuously selected by the normal gacha increases.

  Further, the special lottery executing means executes the special gacha when the number of times that characters of the same rarity are successively selected by the normal gacha is equal to or greater than a second predetermined number that is greater than the first predetermined number. Make sure that the right is associated with the user's identity.

  For example, when a normal character is selected by normal gacha three times in a row, the probability of winning an additional lottery is 33%, and in the case of a normal character being selected four times in a row, the probability of winning an additional lottery. Is 50%, and if five consecutive selections are made, 100% of the additional lottery is won.

  That is, in the present embodiment, for example, when a normal character is selected five times consecutively by the normal gacha, the user always obtains the right to execute the special gacha.

  On the other hand, for example, when the normal character is selected twice consecutively by the normal gacha, and when a character other than normal (for example, rare) is selected by the next normal gacha, the normal character is selected. The number of consecutive selections is reset. Even in this case, if the rare character is selected twice consecutively by the subsequent normal gacha (that is, if the rare character is selected three times consecutively by the normal gacha), the special The lottery execution means 203 executes an additional lottery.

  The special lottery executing means 203 executes a special gacha when the right is executed based on an operation of the user (when special gacha request information described later is received). Specifically, the special lottery execution means 203 is configured to execute the special lottery from the special gacha list when the user touches “execute special gacha!” Displayed on the liquid crystal screen 340 only when the additional lottery is won as shown in FIG. Select a character.

  Further, the special lottery executing means 203 gives the character to the user by associating the information on the character selected by the special gacha with the identification information of the user.

  Note that the special lottery executing means 203 always obtains the right to execute the special gacha even when, for example, a normal character is selected six times or more consecutively by the normal gacha.

  Further, the special lottery executing means 203 executes the special gacha to execute a special gacha to select one character selected from among a plurality of super-rare rare characters when a normal character is selected six times in a row. A super rare character is always given to the user.

  In addition, for example, when a normal character is selected seven times or more consecutively by the normal gacha, the special lottery executing means 203 determines whether to increase the number of super rare characters to the user in the special gacha. A lottery.

  For example, when the normal character is selected seven times in a row by the normal gacha, the special lottery executing means 203 performs a lottery to determine whether to give two super-rare characters to the user by the special gacha. For example, in this case, two super-rare characters are given to the user with a probability of 30%. Also in this case, one super-rare rare character is always given to the user.

  In addition, the special lottery executing means 203 performs a lottery to determine whether or not a maximum of three super-rare characters are to be given by the special gacha when, for example, a normal character is selected eight consecutive times by the normal gacha. For example, in this case, two super-rare characters are provided to the user with a probability of 50%, and three super-rare characters are provided with a probability of 30%.

<Description of Gacha Processing>
Hereinafter, the gacha processing of the present invention will be described with reference to FIG. Note that the control means and the processing procedure described below are merely examples, and embodiments of the present invention are not limited to these. The design of the processing procedure and the like can be changed as appropriate without changing the gist of the present invention.

  First, the normal lottery requesting means 302 of the game device 3 makes a normal gacha request based on a user operation (step S1).

  The normal lottery execution means 202 of the server device 2 that has received the normal gacha request information transmitted from the game device 3 executes the normal gacha (step S2). Thereby, the normal lottery execution means 202 generates information on the character selected by the normal gacha.

  Next, the normal lottery executing means 202 associates information on the character selected by the normal gacha with the user's identification information. Then, information of the character associated with the user identification information is transmitted to the game device 3. Thereby, the character is given to the user (step S3).

  The special lottery executing means 203 determines whether or not the normal character has been continuously selected three times or more by the normal gacha (step S4).

  When it is determined that the normal character has not been selected three or more times consecutively by the normal gacha (S4: NO), the gacha processing of the present invention ends.

  On the other hand, when it is determined that the normal character has been selected three or more times consecutively by the normal gacha (S4: YES), the special lottery executing means 203 causes the normal character to continuously play the normal character five or more times. It is determined whether or not a selection has been made (step S5).

  When it is determined that the normal character is selected five or more times consecutively by the normal gacha (S5: YES), the special lottery executing means 203 associates the right to execute the special gacha with the identification information of the user (step S5). S6). Thereby, the right to execute the special gacha is given to the user.

  Next, the special lottery executing means 203 transmits information on the right associated with the identification information of the user to the game apparatus 3 via the communication means 204. The game execution unit 101 that has received this information via the communication unit 304 displays a virtual button “Execute special gacha!” On the liquid crystal screen 340 (step S7).

  Next, the special lottery requesting unit 303 determines whether a special gacha has been requested based on the operation of the user (step S8).

  When it is determined that the special gacha has been requested (S8: YES), the special lottery executing means 203 executes the special gacha according to the number of times the normal character is continuously selected by the normal gacha. Then, the special lottery executing means 203 associates the character selected by the special gacha with the identification information of the user. Thereby, the character selected by the special gacha is given to the user (step S9).

  Returning to step S8, if it is determined that the special gacha has not been requested (S8: NO), the special lottery executing means 203 reserves the right to execute the special gacha and continuously associates the right with the user identification information. It is left as it is (step S12). The right to execute the special gacha is reserved until the user requests the special gacha. Thereafter, the gacha processing of the present invention ends.

  Returning to step S5, if it is determined that the normal character has not been continuously selected five or more times by the normal gacha (S5: NO), the special lottery executing means 203 executes an additional lottery (step S5). S10).

  Next, the special lottery executing means 203 determines whether or not the additional lottery has been won (step S11).

  When it is determined that the additional lottery has been won (S11: YES), the special lottery executing means 203 gives the user the right to execute the special gacha (step S6).

On the other hand, when it is determined that the additional lottery has not been won (S11: NO), the gacha processing of the present invention ends.
The gacha processing of the present invention is executed by the above procedure.

To summarize the above, the computer program of the present embodiment is:
Server device 2
The normal gacha is executed in response to a request for the normal gacha by the user, a character is selected from a normal gacha list in which a plurality of types of characters are stored, and a normal lottery execution for associating the selected character with user identification information is performed. A means for selecting a character from a special gacha list in which a plurality of types of characters are stored when a character having the same rarity is continuously selected at least a first predetermined number of times (for example, three times) by the normal gacha; Special lottery executing means 203 for associating the right to execute gacha with the identification information of the user,
Function as
The special lottery executing means 203 executes a special gacha to select a character from a special lottery list when the right is executed based on a user operation, and associates the selected character with the user identification information.

<Effect of the Invention>
According to the computer program of the present embodiment, an interesting gacha can be executed.

[Other embodiments]
In the embodiment, an example is described in which a special gacha is executed based on a user operation, but the present invention is not limited to this. For example, when the additional lottery is won, the special lottery executing means automatically executes the special gacha, and in addition to the character selected by the normal gacha, the character selected by the special gacha may be given to the user. .

  Further, in the above-described embodiment, an example is described in which an additional lottery is executed when a normal character is continuously selected three or more times by a normal gacha. However, the first predetermined number of times is determined according to the rarity of the character. Can be changed. For example, an additional lottery may be executed when an extremely rare character is selected two or more times consecutively by normal gacha.

  Also, unlike the above case, if a very rare character is consecutively selected three or more times by the normal gacha, for example, the probability of winning the additional lottery may be increased, and the character with the super-rare character by the special gacha may be increased. May be increased, and the number of selected characters may be increased.

  Further, when a character with a very rare character is selected twice consecutively in the normal gacha, the right to execute the special gacha may be always given to the user.

  Further, as the number of reservations of the right to execute the special gacha increases, the probability that a character with high rarity is won by the special gacha may increase.

  In the above embodiment, an example is described in which the type of character is a rarity, but the present invention is not limited to this. For example, the character type may be an attribute such as a fire attribute, an ability value, an occupation, or the like.

  In this case, for example, when the character with the water attribute is selected three times consecutively by the normal gacha and the additional lottery is won, the character with the water attribute may be always given to the user in the special gacha.

  Further, the present invention can be applied not only when a character having the same rarity is continuously selected for a first predetermined number of times but also when a same character is continuously selected for a predetermined number of times. In this case, for example, the present invention is applied not only when the same character but different characters are continuously selected three or more times, but also when the same character is continuously selected two or more times. Is also good.

  Further, in the above embodiment, the special lottery executing means executes an additional lottery when a character of the same rarity is continuously selected for the first predetermined number of times by the normal gacha, and executes the special gacha when the additional lottery is won. Although an example is described in which the right to perform is given to a user, the present invention is not limited to this.

  For example, immediately after a character with the same rarity is continuously selected by the normal gacha for the first predetermined number of times, the special lottery executing means may automatically execute the special gacha without executing the additional lottery.

  Further, unlike the above case, when a character having the same rarity is continuously selected by the first gacha for the first predetermined number of times, and the additional lottery is won, the special lottery execution means can be performed without requiring the user's operation. The special gacha may be automatically executed. In this case, the special gacha is executed without retaining the right to execute the special gacha for the user.

  Also, different from the above embodiment, when a special gacha is executed, the number of times a character with the same rarity is selected by the normal gacha may be reset. In the above embodiment, if a character with the same rarity is selected three times, four times, and five times consecutively by the normal gacha, the user is always granted the right to execute the special gacha from the fifth time. On the other hand, in this example, the number of consecutive selections is reset by execution of the special gacha.

  Therefore, in this case, unlike the above-described embodiment, for example, when a character with the same rarity is selected three consecutive times and the special gacha is executed, the character with the same rarity is added up to five times by the normal gacha. Special gacha will not always be executed even if selected continuously. Therefore, when the number of consecutive selections is reset by executing the special gacha, the benefit obtained by the user may be reduced depending on the execution timing of the special gacha.

  In addition, even when the number of consecutive selections is reset by execution of the special gacha, a character with the same rarity is selected three times consecutively and a case where four consecutive characters are selected by the normal gacha. If none of the additional lotteries is won, the user is always given the right to execute the special gacha by selecting characters of the same rarity five times consecutively by the normal gacha. However, in this case, the number of consecutive selections does not have to be reset.

  Also, unlike the above embodiment, the right to execute the special gacha is not associated with the user's identification information. After the special gacha is executed, the information of the character selected by the special gacha is associated with the user's identification information. You may.

  In the above embodiment, the game medium is a character, but the game medium may be an item such as a weapon or equipment, or a jewel consumed when performing a gacha.

  Further, in the above embodiment, an example is described in which the computer device is a server device, but the present invention is not limited to this. For example, a game device of one user may function as a server device. In this case, one game device and the other game device may be connected by BLUETOOTH (registered trademark). Further, the gacha may be executed by the game device alone.

  Further, in the embodiment, an example is described in which the game device is a terminal device such as a smartphone, but the present invention is not limited to this. The game device may be, for example, a stationary game device to which a display and a controller are externally connected, or a personal computer.
