Description

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

In recent years, a so-called “gacha” mechanism has been introduced that provides randomly selected game items based on a request from a player. There are various types of conventional gachas, such as a normal gacha, a charging gacha, a comp gacha, a limited time gacha, and an event gacha (see, for example, Patent Document 1).

As a type of conventional gacha, there is a mechanism called step-up gacha or box gacha. The step-up gacha is a mechanism of a gacha that performs a lottery with a low expected value and a low expected value, and then gradually raises the consideration and the expected value.

The box gacha is a mechanism of a gacha that performs a lottery for a limited number of lottery objects (items and the like) so that the once-winning lottery object does not win twice. The box gacha presents the content and number of remaining lottery targets to the player, thereby allowing the player to predict the cost required to acquire all the lottery targets.

JP, 2014-200264, A

The step-up gacha and the box gacha are types of gachas that are highly convenient for the player in that the cost for obtaining all the lottery targets (for example, highly rare items) to be acquired can be predicted. On the other hand, step-up gachas and box gachas are often a high amount of money that is predicted as the cost to obtain all the lottery targets you want to acquire, and it is a mechanism of gachas that is supported by players who are willing to withstand expensive billing. ..

However, the step-up gacha and the box gacha are a mechanism of a gacha with a high threshold for a player whose amount expected to obtain all the lottery objects to be acquired is higher than the budget that can be used by the player.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a lottery mechanism that is supported by both players who are resistant to expensive billing and players who are not.

In order to solve the above-mentioned problem, the claim 1 of the present application provides a computer with a plurality of lottery objects including a plurality of first lottery objects and a plurality of second lottery objects of different types from the first lottery objects. , the lottery information storage means for second drawing object is stored as lottery information in association with a plurality of groups to include one or more, for each of the plurality of the groups, the drawing target remaining associated with the group Table Shimesuru display control means information for specifying the number, accepts extracted election request from the player, based on the winning probability of the second drawing object associated with the more selected the group to the player, to the group the associated select the lottery subject that is not provided to the player from among the drawing object, the drawing means that provide to the player, to function as the selecting means, the group selected by the player When the second lottery target associated with is selected, the winning probability of the second lottery target associated with the group not selected by the player is increased. Is characterized by.

The player information of FIG. 6 has a player ID, a name, and a box lottery ID as items. The player ID is an example of identification information that uniquely identifies the player. The name is the player's name. The box lottery ID is an example of identification information for identifying box lottery information of the player, which will be described later. In the player information of FIG. 6, the box lottery ID of the player who has not started the box gacha is blank, and the box lottery ID is additionally written when the box gacha starts. As described above, the player information of FIG. 6 is associated with the player who started the box gacha, and the box lottery ID of the player is stored.

The storage unit 14 also stores box lottery information as shown in FIG. 7 as lottery information. FIG. 7 is a block diagram of an example of the box lottery information. The box lottery information of FIG. 7 has a box lottery ID, a small box name, the number of remaining items, and a remaining item ID as items. The box lottery ID is an example of identification information that identifies the player's box lottery information, and associates the box lottery information with the player information.

The small box name is the name of the small box for the small box gacha provided in the box gacha. Small boxes with small box names associated with the same box lottery ID are provided in the same box gacha.

The number of remaining items represents the number of items remaining in the small box. The number of remaining items will decrease as the lottery is executed. The remaining item ID represents the item ID of the item remaining in the small box. The box lottery information of FIG. 7 stores the number of remaining items and the item ID for each small box provided in the player's box gacha.

Further, the storage unit 14 stores box creation condition information as shown in FIG. 8 as lottery information. FIG. 8 is a block diagram of an example of box creation condition information. The box creation condition information in FIG. 8 has items such as the number of small boxes, the number of initial items, and the number of rarities per item.

The number of small boxes is the number of small boxes provided in one box gacha. The initial item number is the initial item number of the small box. The number of per-rarity is the number of items with per-rarity in the initial number of items. The box creating condition information of FIG. 8 is used to create a box gacha provided with a plurality of small boxes at the start of the box gacha.

<Process>
<Creating a box gacha>
In the information processing system 1 according to the present embodiment, for example, the box gacha creation process shown in FIG. 9 is executed. FIG. 9 is a flowchart of an example of the box gacha creation process according to this embodiment. Below, the box gacha creation process performed in the information processing system 1 of FIG. 3 will be described as an example. In addition, also in the information processing system 1 of FIG. 4, the process regarding the box gacha is the same as that of the information processing system 1 of FIG.

The box gacha creation process shown in FIG. 9 is performed when, for example, a display request for a box gacha screen is received from a player whose box lottery ID in the player information in FIG. 6 is blank.

In step S11, the gacha lottery section 22 acquires the box creation condition information shown in FIG. 8 from the storage section 14. In other words, the gacha lottery section 22 acquires the number of small boxes, the number of initial items, and the number of rarities per item included in the box creation condition information. In the example of FIG. 8, the small box number “3”, the initial item number “10”, and the winning rarity number “1” are acquired.

In step S12, the gacha lottery unit 22 newly generates a box extraction ID and describes it in the box extraction ID of the player information in FIG. For example, the gacha lottery unit 22 newly generates a box extraction ID “b03” and describes it in association with the player ID “p03”. As a result, the player information and the box lottery information can be associated with each other by the box extraction ID.

In step S13, the gacha lottery section 22 creates the small box names of the small boxes included in the box creation condition information. For example, the gacha lottery unit 22 generates small box names “A”, “B”, and “C” with the small box number “3”.

In step S14, the gacha lottery unit 22 outputs the box extraction information of the number of small boxes based on the box extraction ID, the generated small box name, the number of initial items included in the box creation condition information, and the number of per rarities. to add.

For example, the gacha lottery unit 22 displays the box extraction information of the remaining item number "10" having any of the three small box names "A", "B" and "C" associated with the box extraction ID "b03" in FIG. to add.

The number of remaining items “10” in the box extraction information is the initial value “10” in the box creation condition information of FIG. The remaining item IDs of the box extraction information are the item IDs of the items of one winning rarity corresponding to the winning rarity number “1” of the box creating condition information of FIG. 8 and the winning rarity number “1” from the initial item number “10”. The item IDs of the items of rarity other than the nine hit rarities that have been drawn are the initial values.

By the box gacha creation process of FIG. 9, the gacha lottery section 22 can create a box gacha provided with a plurality of small boxes for each player.

《Item lottery》
In the information processing system 1 according to the present embodiment, a box gacha is executed as shown in FIG. 10, for example. FIG. 10 is a flowchart of an example of the box gacha execution process according to this embodiment.

In step S21, the player performs an operation of selecting the box gacha in the present embodiment on the client terminal 2. The operation receiving unit 50 of the client terminal 2 receives an operation of selecting a box gacha from the player. The request transmission unit 66 of the client terminal 2 makes a request for the box gacha screen to the game server device 3 based on the operation for the box gacha selected by the operation reception unit 50 from the player.

In step S22, the display control unit 24 of the game server device 3 generates a box gacha screen as shown in FIG. 11 based on the player information in FIG. 6 and the box lottery information in FIG. 7, and displays it on the client terminal 2.

FIG. 11 is an image diagram of an example of the box gacha screen. The box gacha screen 1000 in FIG. 11 shows an example of a box gacha provided with three small boxes created by the box creation condition information in FIG. In the box gacha screen 1000 of FIG. 11, the number of remaining items of the per hit rareness and the number of remaining items of the rarity other than the per hit rareness are displayed for each small box, and the number of remaining items of the per hit rarity of the entire box gacha and the other than the hit rareness are displayed. Displays the number of items remaining in rarity.

The box gacha screen 1000 of FIG. 11 displays the number of remaining items of per-rarity and the number of remaining items of rarities other than per-rarity. For example, the number of remaining items and the number of remaining per-rarity included in the number of remaining items are displayed. The number of items may be displayed.

In the box gacha screen 1000 of FIG. 11, the player can select a small box for lottery by pressing an execution button provided for each small box. The selection of the small box may be accepted from the player for each lottery, or may be accepted from the player at the start of the box gacha or after the number of remaining items in the selected small box becomes “0”. Good. The small box may be selected by lottery at the start of the box gacha or after the number of remaining items in the selected small box becomes “0”.

As shown in the box gacha screen 1000 of FIG. 11, in the box gacha of the present embodiment, the player can confirm that each small box has an item of rareness per hit, and the lottery necessary to acquire the item of per hit rareness. The maximum number of times (number of times the number of remaining items in the small box becomes 0) can be known. However, the user cannot know in which small box the rarity item “SR” is contained.

Further, in the box gacha of the present embodiment, as shown in the box gacha screen 1000 of FIG. 11, the player can see that the box gacha provided with three small boxes includes three items of the winning rarity. In addition to being able to confirm, it is possible to know the maximum number of times the lottery is necessary to acquire the items of the three per-rareness items (the number of remaining items in all three small boxes becomes 0).

Therefore, the player can obtain all the items of the rarity in the box gacha of FIG. 11 by performing the lottery the number of times that the remaining items of the three small boxes are all 0 (30 times in FIG. 11). As described above, the box gacha of the present embodiment viewed from a player who is not reluctant to pay a large amount of money can acquire all the items of a low rarity like the box gacha without the small box.

In addition, the player performs a lottery the number of times that the number of remaining items in one small box becomes 0 (10 times in FIG. 11), so that the item of the rare reality in the small box of FIG. Not necessarily).

The box gacha of the present embodiment seen from the player who cannot perform the lottery of the number of remaining items of the three small boxes is 0, unlike the box gacha which has no small box, has the remaining number of items of the small box. You can win rare items in the box by drawing lots of 0 times.

Therefore, the box gacha lottery of the present embodiment is performed by the player who cannot perform the lottery of the number of remaining items in all three small boxes is 0, as compared with the box gacha lottery without the small boxes. The threshold becomes lower.

In this way, the lottery for box gacha according to the present embodiment can be expected to be supported by both players who are resistant to expensive billing and players who are not.

In addition, in the box gacha screen 1000 of the present embodiment, the number of remaining items of the hit rareness and the number of remaining items of the rarity other than the hit rareness are displayed for each small box, and the number of the remaining items of the hit rareness of the entire box gacha and the hit Although the remaining number of items of the rarity other than the rarity is displayed, the information to be displayed is not limited to the number of the remaining items as long as the maximum number of lottery necessary to obtain the item of the rareness can be known. For example, if the remaining number of each small box is displayed, it is not necessary to display either the number of remaining items of the per-rarity or the number of remaining items of the rarity other than the per-rarity. That is, the player can easily know the other remaining number by subtracting one of the remaining items from the remaining number. This also applies to the entire box gacha.

Returning to step S23 of FIG. 10, the game progression unit 20 of the game server device 3 accepts the operation content of the lottery performed by selecting the small box from the client terminal 2, and requests the gacha lottery unit 22 to execute the box gacha. The gacha lottery section 22 performs a box gacha execution process described later, selects an item to be provided to the player, and provides the item to the player.

Proceeding to step S24, the gacha lottery section 22 updates the box lottery information of FIG. 7 according to the item provided to the player. Specifically, the gacha lottery unit 22 reduces the number of remaining items in the box lottery information by “1” and deletes the item ID of the item provided to the player from the remaining item IDs. In the box gacha screen 1000 in FIG. 11, the number of remaining items is updated by executing the box gacha in step S23.

《Box gacha execution process》
The box gacha execution process of step S23 of FIG. 10 is executed by the procedure shown in FIG. 12, for example. FIG. 12 is a flowchart of an example of the box gacha execution process.

In step S31, when the gacha lottery unit 22 is requested to execute the box gacha with the small box selected, it reads the box lottery ID from the player information shown in FIG. 6 of the player who requested the execution of the box gacha. The gacha lottery section 22 refers to the box lottery information corresponding to the selected small box among the box lottery information associated with the read box lottery ID.

In step S32, the gacha lottery section 22 selects one item ID from the remaining item IDs of the box lottery information referred to in step S31. Then, in step S33, the gacha lottery section 22 provides the player with an item corresponding to the selected one item ID.
[Second Embodiment]
In the information processing system 1 of the first embodiment, an example in which the number of initial items of small boxes is the same is shown, but the number may not be the same. When the number of initial items of the small box is not the same, the box creation condition information shown in FIG. 8 of the first embodiment is as shown in FIG. 13, for example.

FIG. 13 is a configuration diagram of another example of the box creation condition information. The box creation condition information of FIG. 13 has a small box name, an initial item number, and a per-rarity number as items. In the box creation condition information of FIG. 13, the number of initial items and the number of rarities per hit are set in association with the small box names of the small boxes.

The box creating condition information of FIG. 13 is used to create a box gacha provided with a plurality of small boxes at the start of the box gacha. By using the box creation condition information of FIG. 13, the gacha lottery section 22 can add box lottery information for displaying the box gacha screen 1000 as shown in FIG.

FIG. 14 is an image diagram of another example of the box gacha screen. The box gacha screen 1000 in FIG. 14 shows an example of a box gacha provided with three small boxes created by the box creation condition information in FIG. From the box gacha screen 1000 of FIG. 14, the player can recognize that the number of remaining items is different for each small box, and therefore the number of remaining items of the rarity other than the winning rarity is different. However, the player does not know in which of the three small boxes the item of the rarity "SR" is contained.

For example, the box gacha screen 1000 of FIG. 14 shows an example in which “small box A” contains 5 items, “small box B” contains 10 items, and “small box C” contains 15 items. In the box gacha screen 1000 of FIG. 14, since the number of items in the “small box A” is 5, the player can select a rare item in the “small box A” by performing a lottery 5 times. Can be earned.

By preparing a small box having a small initial item number in this way, the threshold of the box gacha of the present embodiment is further lowered.
[Third Embodiment]
In the information processing system 1 of the first and second embodiments, the lottery is performed by selecting one item ID from the remaining item IDs. In the third embodiment, the winning probability of winning a prize is set for each small box, and after selecting the winning rare, the item of the rarity corresponding to the drawing result is selected from the remaining item IDs.

FIG. 15 is a configuration diagram of another example of the box lottery information. The box lottery information in FIG. 15 is obtained by adding the winning probability of winning the rarity to the item of the box lottery information in FIG. 7. The winning probability of winning rare represents the winning probability of winning rare in a small box.

In the third embodiment, the box gacha execution process of step S23 of FIG. 10 is executed in the procedure shown in FIG. 16, for example. FIG. 16 is a flowchart of another example of the box gacha execution process.

In step S51, when the gacha lottery unit 22 is requested to execute the box gacha with the small box selected, it reads out the box lottery ID from the player information shown in FIG. 6 of the player who has requested the execution of the box gacha. The gacha lottery section 22 refers to the box lottery information of FIG. 15 corresponding to the selected small box among the box lottery information associated with the read box lottery ID.

In step S52, the gacha lottery unit 22 uses the winning rarity winning probability of the box lottery information referred to in step S51 to perform the winning rareness lottery. When the winning rarity is won, in step S54, the gacha lottery section 22 selects one item ID of the winning rarity from the remaining item IDs of the box drawing information referred to in step S51.

When the winning rarity is not won, the gacha lottery unit 22 selects one item ID other than the winning rarity from the remaining item IDs of the box drawing information referred to in step S51 in step S55. Then, in step S56, the gacha lottery section 22 provides the player with an item corresponding to the one item ID selected in step S54 or S55.

Further, the information processing system 1 of the third embodiment performs the update process of the box lottery information shown in FIG. 17 instead of the update of the box lottery information of step S24 of FIG. 10 after the box gacha execution process of FIG. It may be performed.

FIG. 17 is a flowchart of an example of the box lottery information update processing. In step S61, the gacha lottery section 22 determines whether or not the winning rarity has been won by the box gacha execution processing of FIG.

If the winning rarity is won, the gacha lottery unit 22 increases the winning rarity winning probability contained in the box lottery information of FIG. 15 of the remaining small boxes for which the winning rarity has not been won in step S62.

If the winning rarity has not been won, the gacha lottery unit 22 skips the process of step S62 and maintains the winning rareness winning probability included in the box lottery information of FIG.

In step S63, the gacha lottery section 22 updates the box lottery information of FIG. 15 according to the item provided to the player. Specifically, the gacha lottery unit 22 reduces the number of remaining items in the box lottery information by “1” and deletes the item ID of the item provided to the player from the remaining item IDs.

According to the update processing of the box lottery information of FIG. 17, every time the item of the winning rarity of a certain small box is won, the winning rarity winning probability of the remaining small boxes for which the winning rarity is not won is increased. Here, by displaying the winning probability of winning the rareness on the box gacha screen 1000, the player is motivated to continue the lottery of the remaining small boxes.

Further, even in the case of the box lottery in which one or more items R and nine other items, and small boxes A to C associated with each other are set, the items R or more associated with each small box By changing the variable value of the calculation that defines the probability of winning and the lottery table, the winning probability of items R and above can be made different from a simple 1/10 (10%).

FIG. 20 is an explanatory diagram of another example of the processing for increasing the winning rareness winning probability of the remaining small boxes where the winning rareness has not been won each time the item of winning rareness of a certain small box is won. In FIG. 20, the following formula (1) which defines the probability that items R and above are won is used.

Number of items equal to or greater than R ÷ number of remaining items × variable (1)
For example, in FIG. 20, in the initial stage, the number of items of R or more in the small boxes A to C is 1, the number of remaining items is 10, and the variable is 50%. Therefore, the probability that items R and above are won in the small boxes A to C is 5% from the formula (1).

In addition, in FIG. 20, when the other items are won once from the small boxes A and B after the initial stage, the number of items of R or more in the small boxes A to B is 1, and the number of remaining items is 9 items. , The variable is 50%. Therefore, the probability that items R and above are won in the small boxes A to B is 5.55% from the formula (1). In addition, the probability that items R and above are won in the small box C remains 5%.

After that, when all items are subtracted from the small box A, the variable of the expression (1) changes from 50% to 75%. Since the number of items of R or more in the small box B is 1, the number of remaining items is 9, and the variable is 75%, the probability of winning the items of R or more in the small box B is 8.33% from the formula (1). Becomes Further, since the number of items of R or more in the small box C is 1, the number of remaining items is 10, and the variable is 75%, the probability of winning the items of R or more in the small box C is 7. It will be 5%.

After that, if all the items are also subtracted from the small box B, the variable of the formula (1) changes from 75% to 100%. Since the number of items of R or more in the small box C is 1, the number of remaining items is 10, and the variable is 100%, the probability of winning the items of R or more in the small box C is 10% from the formula (1). ..

According to the processing of FIG. 20, each time an item is drawn from a certain small box, it is possible to increase the hit rareness winning probability of the small box.

In addition, the information processing system 1 of the third embodiment performs an update process of the box lottery information shown in FIG. 18 instead of the update of the box lottery information of step S24 of FIG. 10 after the box gacha execution process of FIG. It may be performed.

FIG. 18 is a flowchart of another example of the box lottery information update process. In step S81, the gacha lottery unit 22 determines whether the number of remaining items in the small box becomes "0" by the box gacha executing process of FIG.

If the number of remaining items in the small box is "0", the gacha lottery unit 22 increases the winning probability of winning in the box lottery information of the remaining small boxes in FIG. 15 in step S82.

If the number of remaining items in the small box is not "0", the gacha lottery section 22 skips the process of step S82 and maintains the winning rareness winning probability included in the box lottery information of FIG.

In step S83, the gacha lottery section 22 updates the box lottery information of FIG. 15 according to the item provided to the player. Specifically, the gacha lottery unit 22 reduces the number of remaining items in the box lottery information by “1” and deletes the item ID of the item provided to the player from the remaining item IDs.

According to the box lottery information update process shown in FIG. 18, every time the number of remaining items in a certain small box becomes “0”, the probability of winning the winning rareness of the remaining small box increases. In general, with box gacha, after the rareness is won, there is no motivation to keep pulling the box to the end. However, according to the update processing of the box lottery information shown in FIG. 18, the player is motivated to continue the lottery of small boxes until the number of remaining items becomes “0” even after winning the rarity.

(Other embodiments)
In the above-described information processing system 1 of the present embodiment, when the winning rarity is set to 3 or more, the winning rarity to be won in a certain small box may be equal to or more than the winning rarity to be won in the previous small box. In addition, in the above-described information processing system 1 of the present embodiment, when the winning rarity is set to three levels or more, the game value of the selected winning rarity is sequentially increased each time the winning rarity item of the small box is won. You may go.

Further, although the example of the box gacha for each player has been described in the information processing system 1 of the present embodiment, a plurality of players may perform the same box gacha. Furthermore, since the information processing system 1 of the present embodiment is provided with a plurality of small boxes in the box gacha, a mechanism may be provided in which a special lottery can be performed when all the small boxes are selected by lottery. With such a mechanism, the player is motivated to perform lottery for all of the small boxes included in the box gacha.

In addition, in the information processing system 1 of the present embodiment, an item of the same rarity (for example, R) may be set as each of the winning rarities in each small box without providing a stage for the winning rarity. If the items have the same rarity but different types of items, the player wants each item according to the player's taste and taste, the progress of the game, the effect set for each item, the parameter for each item, etc. The degree to think is not always the same. For example, as shown in the box gacha screen 1000 of FIG. 19, even if the hit rarities of the small boxes A to C are all the same, the identification information of the item of the hit rarity remaining in the entire box (item ID and item By displaying (name) and the number of remaining items, the player does not know which small box contains the most desired item, so that the same configuration as when a stage is set for the rareness can be realized.

(Summary)
According to the information processing system 1 of the present embodiment, the maximum number of times the lottery is required to obtain all the items of the rare rarity included in the box gacha, and the small box for each small box provided in the box gacha. It is possible to present the player with the maximum number of times the lottery is required to obtain the item of the winning rarity included in.

Therefore, the player obtains the cost of the lottery necessary to acquire all the items of the rare rarity included in the box gacha, and the item of the rare rarity included in the small box for each small box provided in the box gacha. You can predict the cost of the lottery required to do.
