Description

The present invention relates to game programs, game devices and game systems.

Conventionally, there is known a technique of giving a game medium such as an item or a character to a user by executing a lottery (hereinafter, also referred to as “gacha”) (see Non-Patent Document 1). Regarding the game media to be selected in this technique, different types of game media such as characters and items may coexist.

"What is the meaning of the yaminabe in Dragalia Lost's gacha? Exposing the contents that are too dangerous!", [Online], Kakeji Temple for non-payers, [June 29, 2nd year of Reiwa], Internet, <https: // possangames.work/dragalia-lost-gacha-dark-pot/>

In a gacha where different types of game media are mixed in the conventional technology, when the user wants to acquire a combination of a specific type of game medium (for example, a combination of a character "warrior" and an item "sword" that a warrior can equip). There is. However, acquiring a specific type of combination is more difficult than acquiring a specific game medium alone because the probability is the product of the winning probabilities of each type of game medium.

In order to acquire a specific type of game medium combination that is more difficult as described above, the user may repeatedly redraw the gacha or redo the first gacha by resetting the game (so-called "Resemara"). .. If the gacha is repeatedly redone in this way, it becomes difficult for the user to maintain an interest in the gacha, and there is a risk that the interest in the gacha will be lost at an early stage.

The present disclosure provides a game program, a game device, and a game system that can improve the interest of acquiring a game medium in a lottery in which different types of game media are mixed.

After logging in, the game device 5 receives data necessary for game progress (data related to the game progress) from the server device 2, and outputs game images and sounds to the display 61 and the speaker 62 based on the user's operation while outputting the game image and sound to the display 61 and the speaker 62. Advance the game.

<Configuration of game system 1>
Hereinafter, each hardware configuration of the server device 2 and the game device 5 will be described with reference to FIG. 1. It should be noted that each of the plurality of game devices 5 has the same configuration as each other.

<Configuration of server device 2>
As shown in FIG. 1, the server device 2 has a network interface 21, a storage unit 22, and a control unit 23. The network interface 21 and the storage unit 22 are electrically connected to the control unit 23 via the bus 29.

The network interface 21 is communicably connected to each game device 5 via a communication network 6 such as the Internet and a LAN.

The storage unit 22 is composed of an HDD (Hard Disk Drive), a RAM (Random Access Memory), a ROM (Read Only Memory), an SSD (Solid State Drive), and the like. The storage unit 22 stores various data such as the user DB 221 and the lottery list 222, in addition to various programs including a part of the game program according to the present embodiment.

In the user DB 221, information (status, etc.) about the player character operated by the user, the amount of the consumption medium that can be used in the virtual game space, etc. are stored in association with each identification number of the user who plays the game. ing.

Here, the consumption medium is a currency, points, or the like that can be used in the virtual game space, and is a medium that is consumed in the game when the game is advanced. The consumption medium is given to the user as a reward for clearing the quest and by charging in the real world.

The lottery list 222 is used when the lottery execution means 233 (described later) performs a lottery process generally called a gacha, and includes a plurality of information regarding the game medium to be selected. As shown in FIG. 2, the lottery list 222 contains information about the game medium (name, parameters (rare value (hereinafter referred to as “rareity”), level, etc.), etc.) and the winning probability (selection ratio) by lottery. , Is associated. In this embodiment, an example in which the parameters of the game medium are set to rarity and the values of rarity are set to three stages of S rare, A rare, and B rare will be described, but the present invention is not limited to this.

"Gacha" is a method of selecting an arbitrary game medium from the lottery list 222 by lottery based on a predetermined winning probability on the server device 2. Any selected game medium is attached to the user's game device 5. "Giving the game medium selected by the gacha to the user / owned by the user" is synonymous with "associating / associating the game medium selected in the lottery process with the identification information indicating the user". be.

The "game medium" is electronic data representing elements related to the game, and includes the name of the character used as the player character, items (weapons, armor, tools) used by the player character in the virtual game space, and the like. Is done. The user can obtain the game medium by direct purchase by charge, clearing the quest, or by a lottery method called gacha. The obtained game medium is stored and managed in the user DB 221 in association with the identification information of the user who owns the game medium.

The control unit 23 is composed of a microcomputer including a CPU and a semiconductor memory, and controls the operation of the own device 2.

By executing various programs, the control unit 23 functions as an information processing means 231, a collation means 232, a lottery execution means 233, a probability changing means 234, and a change canceling means 235.

-Information processing means-
The information processing means 231 transmits and receives various data to and from each game device 5. The main data received by the information processing means 231 includes download request information of a game program, a gacha lottery request according to a user's operation, a quest execution request, account information, and the like. The main data transmitted by the information processing means 231 includes information for confirming that the game device 5 has received the game program, information on the game medium obtained by the gacha, and the like.

-Verification means-
The collation means 232 authenticates the user account using the user identification information received from the game device 5.

-Lottery execution means-
The lottery executing means 233 selects one or more game media from the lottery list 222 based on the winning probability for each game medium in accordance with the lottery request for gacha (hereinafter, also simply referred to as “request”). .. The lottery execution means 233 associates the information about the selected game medium with the identification information of the user who performed the operation that is the transmission source of the lottery request in the user DB 221. As a result, the user is given a game medium that has been won as a result of drawing a gacha by himself / herself.

The lottery execution means 233 executes a lottery of the game medium in response to the user's request. Specifically, first, the control unit 56 of the game device 5 receives a request from the user via the touch pad 63 and the operation unit 54. Next, the control unit 56 transmits the received request to the lottery execution means 233 of the server device 2 via the network interface 51. Next, when the lottery execution means 233 receives the request, the lottery execution means 233 selects one or more game media from the lottery list 222 based on the winning probability for each game medium in response to the request by lottery.

The game medium includes a first-class game medium and a second-class game medium. The second-class game medium is a game medium of a type different from that of the first-class game medium. In the present embodiment, when the type of the first-class game medium is "character", the description will be made using an example in which the type of the second-class game medium is "equipment item" different from the character, but the purpose is limited to this. is not.

The game medium is divided into a plurality of categories. For example, in a game medium of the type "character", it is classified into categories such as "warrior" and "witch". Further, the game medium is classified into categories such as "sword" and "cane" in the game medium of the type "equipment item", for example.

Hereinafter, for the sake of simplicity, for example, the game medium classified into "warrior" is also simply referred to as "warrior", and the game medium classified into "sword" is also simply referred to as "sword". Further, for the sake of simplicity of explanation, when the parameter used for the change processing of the winning probability of the probability changing means 234 is "rareity", for example, a sword whose rarity is "S rare" is referred to as "sword". Also called "S rare".

-Probability changing means-
The probability changing means 234 is a type 2 game suitable for the winning type 1 game medium when the lottery of the game medium is executed from the next time onward after the type 1 game medium is won by the lottery execution means 233. The winning probability of the medium is changed according to the parameters of the winning first-class game medium.

The "type 2 game medium suitable for the type 1 game medium" is, for example, a type "equipment item" different from the character when the type is "character" and the warrior's game medium is the type 1 game medium. However, the "sword" that can be equipped by a warrior corresponds to the second type game medium.

In the probability changing means 234, after the warrior is elected as the first type game medium, the winning sword has a winning probability of a sword suitable for the winning warrior when the lottery of the game medium is executed from the next time onward. Change according to the parameters. For example, when the warrior's rarity is S rare, the probability changing means 234 changes the winning probability of the sword to be lower than the original value (hereinafter, also simply referred to as "decrease" or "down"). As another example, the probability changing means 234 changes the probability of winning a sword to be higher than the original value when the warrior's rarity is B rare (hereinafter, simply "increase" or "up"). Also called). Here, the "original value" means the value before the change of the winning probability for each game medium stored in the lottery list 222.

According to the above configuration, the probability changing means 234 changes the value of the winning probability of the second-class game medium to be lower than usual, for example, if the value of the parameter of the winning first-class game medium is relatively high. can do. As described above, according to the above configuration, it is possible to provide an opportunity to stop redoing the gacha when the first-class game medium having an excellent parameter value is acquired. That is, according to the above configuration, it is very difficult to acquire the second-class game medium whose winning probability is low by acquiring the first-class game medium, so that the user is repeatedly re-doed with the gacha. It can provide an opportunity to stop. On the contrary, the probability changing means 234 can make the value of the winning probability of the second-class game medium higher than usual to make it easier to obtain, and can prevent the gacha from being repeated again. Therefore, according to the above configuration, the probability changing means 234 can improve the interest in acquiring different types of game media.

In the probability changing means 234, for example, after the first type game medium is won by the lottery execution means 233, the winning first type game medium satisfies the first condition when the lottery of the game medium is executed from the next time onward. In this case, among the second-class game media suitable for the winning first-class game medium, the winning probability of the second-class game medium that satisfies the second condition is increased, and the second-class game medium that does not satisfy the second condition is used. You may reduce the winning probability.

The "first condition" is a condition for determining whether or not to change the winning probability of the second-class game medium according to the parameters of the winning first-class game medium and the like. Further, here, the "second condition" is a condition for determining whether to increase or decrease the winning probability of the second type game medium according to the parameters of the second type game medium or the like.

According to the above configuration, the probability changing means 234 can change whether or not to change the winning probability of the second-class game medium depending on whether or not the first-class game medium satisfies the first condition. .. Further, according to the above configuration, the probability changing means 234 can change the mode of changing the winning probability depending on whether or not the second condition is satisfied for the second type game medium. Therefore, according to the above configuration, the probability changing means 234 can have variations in changing the winning probability of the second-class game medium according to the first condition and the second condition.

The first condition includes, for example, that the parameter of the winning first-class game medium is equal to or higher than the first threshold value. The second condition also includes that the parameter of the second-class game medium is equal to or less than the second threshold value.

According to the above configuration, when the parameter of the first-class game medium is equal to or higher than the first threshold value, the probability changing means 234 acquires a second-class game medium whose parameter exceeds the second threshold value in the subsequent lottery. It can be made difficult, and it is possible to easily acquire a parameter having a parameter equal to or less than the second threshold value. Therefore, according to the above configuration, for example, when the probability changing means 234 wins a first-class game medium with a high rarity, the second-class game medium with a high rarity is acquired in the subsequent lottery. It can be made difficult. Therefore, according to the above configuration, the probability changing means 234 reduces the feelings of the user who repeats the lottery to acquire the first-class game medium with high rarity and to somehow acquire the second-class game medium with high rarity accordingly. It is possible to stop the repetition of the lottery at the time when the first-class game medium with high rarity can be acquired.

The probability changing means 234 is, for example, when the second type game medium whose winning probability is changed is won after changing the winning probability of the second type game medium, the second type winning is performed when the next lottery is executed. The winning probability of the first-class game medium suitable for the seed game medium is changed according to the parameters of the winning second-class game medium.

According to the above configuration, for example, when the winning second-class game medium is the B rare of the sword, the probability changing means 234 increases the winning probability of the S rare of the warrior having a rarity contrary to the B rare from the normal value. Can be made to.

<Lottery execution means and probability changing means>
Here, an example of processing of the lottery executing means 233 and the probability changing means 234 will be described with reference to FIG. FIG. 2 is a table showing an example of the lottery list 222 in the game system 1. In the winning probability of the lottery list 222 of this example, "-(hyphen)" or "Stay" remains the original value, "UP" is the value increased from the original value, and "Down" is the original value. Shows the downed value.

FIG. 2A shows a lottery list 222 used for the first lottery, FIG. 2B shows a lottery list 222 used for the second lottery following the first lottery, and FIG. 2C shows the second lottery list. The lottery list 222 used for the third lottery is shown. This 1 to 3 consecutive lottery is typically a lottery for 3 consecutive times among the so-called N consecutive gachas in which 1 to N times of gacha are continuously executed, but the purpose is not limited to this.

In this example, in order to simplify the explanation, an example in which the winning probability is associated with each type / category of the game medium and each rarity in the lottery list 222 will be described. Strictly speaking, each category includes a plurality of game media, and each game medium is associated with a rarity and a winning probability. In this example, in order to further simplify the explanation, it is expressed that each information is directly associated and stored in one list, but the purpose is not limited to this.

In this example, the first condition is that the rarity (parameter) of the winning first-class game medium is S rare (first threshold value) or higher. Further, in this example, the second condition is that the rarity of the second-class game medium is B rare (second threshold value) or less.

As shown in FIG. 2, the lottery list 222 includes different types of game media such as characters (eg, "warrior", "witch", etc.) and equipment items (eg, "sword", "wand", etc.). ing. In addition, a game medium in which the value of each rarity is S rare, A rare, and B rare is included for each type / category.

First, as shown in FIG. 2A, for example, it is assumed that the lottery execution means 233 executes the first lottery and the warrior S rare is elected as the first type game medium. At this time, the winning warrior's S rare satisfies the first condition because the rarity is S rare (first threshold) or higher.

Next, as shown in FIG. 2B, when the lottery execution means 233 executes the second lottery, the probability changing means 234 is suitable for the warrior of the first-class game medium that has been won in the lottery list 222. Change the rarity of a sword of a different type (equipment item) as a type 2 game medium. Specifically, the probability changing means 234 lowers the winning probability of the S rare of the sword and increases the winning probability of the B rare of the other sword. In addition, when the probability changing means 234 lowers the winning probability of a specific game medium in this way, the winning probability of another game medium is increased by increasing the winning probability of the entire winning probability (winning of all game media). Adjustment so that the total probability is "1").

Next, it is assumed that the lottery execution means 233 executes the second lottery, and the B rare of the sword that is suitable for the warrior of the first type game medium and whose winning probability is changed is won.

Next, as shown in FIG. 2C, when the lottery executing means 233 executes the third lottery, the probability changing means 234 determines the winning probability of the warrior suitable for the winning sword in the lottery list 222. Change according to the rarity (B rare) of the winning sword. Specifically, the probability changing means 234 increases the winning probability of the S rare of the warrior who has a rarity contrary to the rarity of the winning sword (B rare), and makes it the rarity of the winning sword (B rare). Reduces the winning probability of B rare of a warrior with the corresponding rarity.

According to the above configuration, the probability changing means 234 can reduce the winning probability of the S rare sword suitable for the warrior in the second lottery when the S rare warrior is won in the first lottery. .. Therefore, according to the above configuration, the probability changing means 234 can make it more difficult to acquire a combination of a warrior's S rare and a sword's S rare in one N-series gacha. On the other hand, the probability changing means 234 can increase the winning probability of the B rare of the sword suitable for a warrior. Therefore, according to the above configuration, it is very difficult to obtain a combination of the S rare of the warrior and the S rare of the sword no matter how many times the N-ren gacha is redone. can do.

The explanation will be continued by returning to FIG. The probability changing means 234, for example, after changing the winning probability of the second-class game medium, even if the first-class game medium suitable for the second-class game medium is won, when the next lottery is executed, the probability changing means 234 is executed. The winning probability of the second-class game medium whose winning probability has been changed is not further changed.

For example, even if the warrior wins again in the third lottery in the example of FIG. 2, the probability changing means 234 regains the winning probability of the sword whose winning probability has already been changed when the fourth lottery is executed. It does not change.

According to the above configuration, the probability changing means 234 can prevent the winning probability of the second-class game medium from being double-changed. Therefore, according to the above configuration, the probability changing means 234 suppresses that the winning probability is extremely lowered or conversely increased as compared with the original value.

In other cases, for example, if the warrior's S rare game medium wins and the sword's S rare win probability is changed (down), then the warrior's B rare wins, the sword's S rare win probability. Will return to the original value. In this case, it is conceivable that the S rare of the sword, which is difficult to acquire, can be acquired as usual. According to the above configuration, after changing the winning probability of the S rare of the sword, the winning probability of the S rare of the sword can be maintained even if the B rare of the warrior is won.

When the first cancellation condition is satisfied, the probability changing means 234 changes the winning probability of the second-class game medium, and then the first-class game medium suitable for the second-class game medium is won. Accordingly, when the next lottery is executed, the winning probability of the second-class game medium in which the winning probability is changed is further changed. That is, when the first cancellation condition is satisfied, the probability changing means 234 changes the winning probability of the second-class game medium in which the winning probability is changed again when the next lottery is executed.

The "first cancellation condition" is a condition for determining whether or not to further change the winning probability of the game medium in which the winning probability has been changed. In other words, the first condition is also a condition for enabling the re-change of the winning probability in the probability changing means 234. The first cancellation condition and the second cancellation condition described later are collectively referred to as "cancellation condition".

The cancellation condition includes, for example, (a) the lottery execution means 233 executing a predetermined number of lottery, or receiving a user's request for executing the lottery a predetermined number of times. In other words, the winning probability changed by the probability changing means 234 is inherited for a predetermined number of times, and then returns to the original value. Here, the "predetermined number of times" is, for example, the number of times set in common by the users in the game system 1, the number of times set in response to the user's request, and the like.

According to the above configuration, the change of the winning probability can be inherited for the set number of times and automatically returned to the original value.

The cancellation condition includes, for example, (a) a predetermined period elapses from the time when the lottery execution means 233 executes the lottery. Here, the "predetermined period" is, for example, a period set for all users in the game system 1, or a period set in response to a user's request. The predetermined period is, for example, one day (the day) or one week from the time when the lottery execution means 233 executes the lottery.

According to the above configuration, the probability changing means 234 can take over the change of the winning probability and automatically return it to the original value during the set period.

The cancellation condition is, for example, (c) an event including a lottery in which a first period and a second period are set in common for a plurality of users, and the second type game medium is won within the first period. Includes that the probability is changed and the first period elapses. For example, if the total duration of the event is two weeks, the first period will be one week in the first half and the second period will be one week in the second half. The probability changing means 234 returns the changed winning probability to the original value when the first half week has passed.

According to the above configuration, the probability changing means 234 can take over the change of the winning probability during the set first period and automatically return it to the original value when moving from the first period to the second period. According to the above configuration, for example, the S rare sword that was changed so that the winning probability goes down in the first half of the event returns to the original winning probability in the second half of the event, so the interest in the lottery is lost in the second half of the event. Suppress being struck.

The cancellation condition may be, for example, a combination of at least any two of the above (a) to (c).

The "event" includes a lottery with a fixed implementation period, in other words, a lottery for a limited time, so-called event gacha. The first period is the first half of the event, and the second period is the second half of the event.

According to the above configuration, the change release means 235 maintains the changed winning probability value in the gacha carried out in the first half of the entire period of the event, and is carried out in the second half after the first half. In the case of Gacha, the change of winning probability can be returned to the normal value.

In the probability changing means 234, for example, after changing the winning probability of the second-class game medium suitable for the winning first-class game medium, the second-class game medium unsuitable for the winning first-class game medium is won. If so, when the next lottery is executed, the winning probability of the first-class game medium suitable for the winning second-class game medium is changed according to the parameters of the winning second-class game medium.

For example, after changing the winning probability of a different type of sword (type 2 game medium) suitable for the winning warrior (type 1 game medium) by the probability changing means 234, a different type of wand that is not suitable for the warrior (type 1 game medium) It is assumed that the second type game medium) is won. In this case, the probability changing means 234 determines the winning probability of a different type of wizard (type 1 game medium) suitable for the winning wand according to the rarity of the winning sword when executing the next lottery. change.

According to the above configuration, the probability changing means 234 is a first-class game medium suitable for the second-class game medium when the second-class game medium not suitable for the winning first-class game medium is won. You can change the winning probability of. Therefore, according to the above configuration, the probability changing means 234 is suitable for the second type game medium while preventing the winning probability of the game medium from being double updated or returning to the original value. The winning probability of the game medium can be changed.

The probability changing means 234 changes, for example, the winning probability of the second-class game medium according to the number of categories of the first-class game medium suitable for the second-class game medium. Here, the "number of divisions" is, for example, the number of jobs that can be equipped in the case of divisions distinguished by the role (job) of the character. The probability changing means 234, for example, divides the fluctuation range of the winning probability by the number of divisions of the character (first-class game medium) suitable for the sword to reduce the value. The probability changing means 234 lowers the winning probability of the sword by this small fluctuation range.

According to the above configuration, the probability changing means 234 is changed according to the number of categories of the first-class game medium that can be equipped with this equipment item, that is, the characters that can be equipped, for example, when the second-class game medium is an equipped item. can do. According to the above configuration, the probability changing means 234 obtains a combination of a specific character and this specific character-specific equipment item, for example, by increasing the range of downing as the number of specific character-specific equipment items, that is, the number of divisions is small. It may be difficult.

-Means to cancel the change-
The change canceling means 235 cancels the change of the winning probability by the probability changing means 234 based on the second cancellation condition. Here, "cancelling the change of the winning probability" means returning the changed winning probability value to the original value before the change. The second cancellation condition is a condition for determining whether or not to return the changed winning probability value to the original value.

The second cancellation condition, like the first cancellation condition, includes at least one of the above conditions (a) to (c).

According to the above configuration, the change canceling means 235 can automatically return the changed winning probability value to the original value if conditions such as the lottery executing means 233 executing the lottery a predetermined number of times are satisfied.

<Flow of operation of game system 1>
The flow from the lottery execution process to the release process of changing the winning probability will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of these processes.

In this example, a so-called 10-game gacha example in which 10 lottery games are continuously executed will be described. The initial value of N is "1". Further, in this example, the first cancellation condition is "execution of a predetermined number of lottery (in this example, 5 times)".

As shown in FIG. 3, the lottery execution means 233 of the server device 2 executes the Nth lottery of the game medium in response to the user's request (step st1).

Next, the lottery execution means 233 associates the game medium with the user by executing the Nth lottery (step st2).

Next, when the winning game medium satisfies the first condition (Yes in step st3), and the winning probability of a different type of game medium suitable for the winning game medium has not been changed, or the winning probability is When re-change is possible (Yes in step st4), the probability changing means 234 changes (including re-change) the winning probability of a different type of game medium suitable for the winning game medium (step st5). ).

For example, if the winning game medium is a first-class game medium, the parameter of the game medium is equal to or higher than the first threshold value (Yes in step st3), and the second-class game medium suitable for this game medium. When the winning probability has not been changed (Yes in step st4), the probability changing means 234 changes the winning probability of the second-class game medium (step st5).

On the other hand, if the winning game medium is a type 2 game medium, the parameter of the game medium is equal to or higher than the first threshold value (Yes in step st3), and the type 1 game medium suitable for this game medium. When the winning probability has not been changed (Yes in step st4), the probability changing means 234 changes the winning probability of the first-class game medium (step st5).

Next, when the first cancellation condition that the lottery executing means 233 executes the lottery five times is satisfied, that is, when N = 5 (step st6), the probability changing means 234 re-changes the winning probability of the game medium. Release (step st7).

When the number of lottery executions is less than 10 (No of stap st8), the control unit 23 increments N (step st9). When N is incremented, the process returns to before step st1 in the flowchart.

When the number of lottery executions reaches 10 (Yes in step st8), the process shown in FIG. 3 ends.

Summarizing the above, the control unit 23 (computer) of the server device 2 is a lottery execution means 233 that executes a lottery of a game medium in response to a user's request, and the game medium is a first-class game medium and a first-class game medium. When the lottery of the next and subsequent game media is executed after the first-class game medium is won by the lottery execution means 233 and the lottery execution means 233, including the second-class game medium of a type different from the first-class game medium. In addition, it functions as a probability changing means 234 that changes the winning probability of the second-class game medium suitable for the winning first-class game medium according to the parameters of the winning first-class game medium.

<Effect>
According to the present embodiment, for example, if the value of the parameter of the winning type 1 game medium is relatively high, the value of the winning probability of the type 2 game medium can be changed to be lower than usual. On the contrary, according to the present embodiment, if the value of the parameter of the winning type 1 game medium is relatively low, the winning probability value of the type 2 game medium is set lower than usual. You can also make it easier. In either case, it is possible to prevent the user from repeating the gacha redo. Therefore, according to the present embodiment, it is possible to improve the interest in acquiring different types of game media.

[Modification example]
Although the present invention has been described based on the above embodiment, the present invention is not limited to the above embodiment. The following cases are also included in the present invention.

[First modification]
In the above embodiment, the example of the so-called N-series gacha in which the lottery for N times is continuously executed has been described, but for example, a single lottery, a so-called single-shot gacha, may be executed in the order of a plurality of times. "Running in sequence" means running a single lottery and the next single lottery in order, with a certain period of time between these single lottery runs and other events. Do not deny that it will be done.

[Second modification]
In the above embodiment, the game medium, its winning probability, and its rarity are directly associated and stored in the lottery list 222, but for example, they are indirectly associated with each other over a plurality of lists. May be stored. For example, there may be a list in which the rarity and the winning probability are associated with each other, and a list for each rarity in which the game medium and the winning probability are associated with each other. In this case, the lottery execution means 233 first executes the lottery of the rarity, and then executes the lottery of the game medium in the winning rarity.

[Third modification example]
Although not shown in the above embodiment, the probability changing means 234 is the same as the winning first-class game medium when, for example, after the first-class game medium is won, the next and subsequent game medium lottery is executed. The winning probability of the type of game medium, that is, the first-class game medium may be changed according to the parameters of the winning first-class game medium.

Here, an example of processing of the lottery executing means 233 and the probability changing means 234 will be described with reference to FIG. FIG. 4 is a table showing an example of the lottery list 222 in the game system 1. The premise of the notation and the conditions to be applied are the same as those in FIG.

FIG. 4A shows a lottery list 222 used for the first lottery, FIG. 4B shows a lottery list 222 used for the second lottery following the first lottery, and FIG. 4C shows the second lottery list. The lottery list 222 used for the third lottery is shown.

First, as shown in FIG. 4A, for example, it is assumed that the lottery execution means 233 executes the first lottery and the warrior S rare is elected as the first type game medium. At this time, the winning warrior's S rare satisfies the first condition because the rarity is S rare (first threshold) or higher.

Next, as shown in FIG. 4B, when the lottery execution means 233 executes the second lottery, the probability changing means 234 has the same type as the winning first-class game medium warrior in the lottery list 222. Decrease the winning probability of the warrior in the category and increase the wizard of the same type / different category. Further, the probability changing means 234 changes the rarity of the winning list 222 by using a sword of a different type (item) suitable for the warrior of the first-class game medium as the second-class game medium. Specifically, the probability changing means 234 lowers the winning probability of the S rare of the sword and increases the winning probability of the B rare of the other sword.

Next, it is assumed that the lottery execution means 233 executes the second lottery, and the B rare of the sword that is suitable for the warrior of the first type game medium and whose winning probability is changed is won.

Next, as shown in FIG. 2C, when the lottery executing means 233 executes the third lottery, the probability changing means 234 determines the winning probability of the warrior suitable for the winning sword in the lottery list 222. Change according to the rarity (B rare) of the winning sword. Specifically, the probability changing means 234 increases the winning probability of the S rare of a warrior having a rarity that is contrary to the rarity of the winning sword (B rare), that is, restores the value lower than the original value. Not only will it be improved further. On the other hand, the probability changing means 234 raises the winning probability of the A rare of the warrior having a rarity higher than the rarity (B rare) of the winning sword to return to the original value.

According to the above configuration, the probability changing means 234 can make it difficult to acquire a game medium of the same type and category as the game medium once won. Further, according to the above configuration, the probability changing means 234 can restore the winning probability of the game medium, which has been difficult to obtain, when a different type of game medium suitable for the winning game medium is won. can.

[Fourth variant]
The value of the winning probability of the game medium at the first time of the lottery may be set to an initial value common to all users, or may be set to a value adjusted according to the acquisition / possession status of the user's game medium. The term "first time" as used herein means, for example, when the lottery is executed for the first time after installing the game program on the game device 5 (including resetting the game), after the change in the winning probability is canceled. It may include the time when the lottery is executed for the first time, or the time when the lottery is executed for the first time after logging out from the previous lottery.

For example, when the user acquires the S rare of the warrior in the previous lottery or when the user owns the S rare of the warrior, the control unit 23 sets the value of the winning probability of the S rare of the sword from the initial value. It may be adjusted to bring it down. Further, for example, when the user has a large number of S rares of the warrior and B rares of the sword, the control unit 23 may adjust the value of the winning probability of the S rare of the sword to be increased from the initial value. good. The control unit 23 may set these adjusted winning probability values in the winning probability field of the lottery list 222.

[Fifth variant]
In the above embodiment, regarding the flow from the lottery execution process to the release process of changing the winning probability, in the example of FIG. 3, (a1) the fifth lottery is executed and the first release condition is satisfied → (b1) 6 An example of the flow in which the game medium is won in the second lottery (trigger for re-change) → (c1) The winning probability of a different type of game medium suitable for the winning game medium is changed again toward the seventh lottery. As explained, but not limited to this. For example, if the first cancellation condition is "accept the user's request for executing the lottery a predetermined number of times (six times in this example)", (a2) the first type game medium is set in the fifth single-shot gacha. Winning (trigger of re-change) → (b2) The first cancellation condition is satisfied by accepting the 6th single-shot gacha → (c2) Re-changing the winning probability of 2 types of game media when executing the 6th single-shot gacha But it may be. That is, the order in which the first cancellation condition is satisfied and the trigger for re-changing the winning probability may change.
