Description

  The present invention relates to a game system, an item distribution method, and a program capable of appropriately distributing items acquired jointly by a plurality of users to each user.

Conventionally, various games have been provided in smartphones and game devices. For example, in a social game or the like, an item lottery (lottery game) called “gacha” can be executed.
In this gacha, for example, a lottery is performed based on a winning probability set for each item, and the winning item is given to the user. Higher rank items (items with a higher degree of rarity) that can advance the game more advantageously have lower winning probabilities, so even if you run many gachas, such high rank items May not be available.

  Recently, an item lottery of a type in which a plurality of gachas are continuously executed, as represented by “10-line gacha”, is also known. For example, Patent Document 1 discloses an invention of a game device characterized in that, in ten consecutive gachas, lottery is performed so that the same type of items (cards) do not win.

Japanese Patent No. 6284105

The above-mentioned 10 consecutive gachas are attractive item lotteries for users, such as one or more high-ranking items must be won. Still, since the consideration (in-game currency, billing items, etc.) to be consumed is high to some extent, light users (for example, beginners of the game) and the like often cannot participate in the 10-game gacha.
For this reason, it is also conceivable that a plurality of users can participate and perform ten consecutive gacha. In other words, even if the user alone is expensive, the consideration required for participation can be kept low if one of the plurality of users cannot pay the 10-unit gacha consideration. Therefore, even a light user or the like can participate in such a ten-line gacha.

However, in the case where a plurality of users participate and can perform 10 consecutive gachas, there is a concern that troubles may occur between users depending on how the items acquired jointly are distributed to each user.
In particular, as to which user is given a high-rank item that can be acquired with 10 consecutive gachas, if the fairness is not maintained, it will be a compliment among users. Therefore, it is easy to conclude that it is better to have the game system decide at random, avoiding making adjustments between users.
Even so, if the game system performs everything from lottery to distribution of items, the fairness will be maintained, but the user will not be involved at all, and some users may feel that it is simply luck and lacks interest Many.

  For this reason, when a plurality of users can participate and perform 10 consecutive gachas, a technology that allows the user to be involved to the extent that the fairness is not impaired, and allows the items to be allocated in a form that is easy for the user to understand. It was sought after.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a game system, an item distribution method, and a program capable of appropriately distributing items acquired jointly by a plurality of users to each user. And

The game system according to the present invention includes:
A game system that provides a lottery game in which a plurality of users participate together,
When the lottery game is started, a lottery unit for drawing a plurality of items;
For some or all of the plurality of items selected by the lottery unit, at least a part of the information related to the item is changed to a secret item that is concealed, and the plurality of items including the secret item are changed to the plurality of users. A presentation unit to present to,
A collection unit that collects selection information of items selected by the plurality of users from among the plurality of items including the secret item presented by the presentation unit;
A granting unit for granting each of the selected items to any selected user according to the selection information collected by the collecting unit;
It is characterized by providing.

  According to the present invention, items acquired jointly by a plurality of users can be appropriately distributed to each user.

Embodiments of the present invention will be described below. In the following, in order to facilitate understanding, an embodiment in which the present invention is applied to a game system that controls a game (such as a social game) that is executed using a smartphone or the like will be described. For example, the present invention can be similarly applied to control various games executed using an information processing apparatus such as a notebook personal computer, a game machine, or a PDA (Personal Digital Assistant).
In other words, the embodiments described below are for illustrative purposes and do not limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

(overall structure)
As shown in FIG. 1, the game system 100 according to the embodiment of the present invention is configured such that a game server 200 and a user terminal 300 are communicably connected via the Internet 900.
Although simplified in the figure, it is assumed that there are a large number of user terminals 300 according to the users to be used.

The game server 200 is, for example, a server device (server computer) or the like, and communicates with the user terminal 300 to control the progress of a game (for example, a social game).
In the game controlled by the game server 200, a lottery game called “gacha” can be executed. That is, when execution of gacha is requested from the user terminal 300, the game server 200 performs a lottery from an item group based on a lottery condition in which a winning probability or the like is set for each item. To the user of the terminal 300.
Further, the “item” is not limited to a general item in the game, and will be described below as including, for example, a character, weapon, armor, magic, skill, and the like.

As an example, in the game controlled by the game server 200, three types of gachas including “single gacha”, “ten gachas”, and “ten gachas together” can be executed.
Single-shot gacha is a basic gacha that, for example, draws one item per gacha and grants the selected item to the user. For example, coins that are in-game currency The amount is set low.
Ten consecutive gacha is a gacha that, for example, 10 gachas are continuously performed, a total of 10 items are drawn, and the winning items are given to the user, and the amount of consideration to be consumed is high (as an example, It is characterized in that one or more items of high rank (platinum rank described later) are always won. Note that the names of ten consecutive gachas and the number of consecutive gachas (10 times) are examples, and other names (multiple times) of gachas are continuously performed with other names. It may be.
These single-shot gachas and 10-line gachas are gachas that the user challenges alone, and when the price is consumed, the items are selected and the selected item is given to the user. .

On the other hand, the 10-game gacha is a 10-game gacha characterized by a plurality of users participating. That is, even in a situation where the user alone cannot pay the expensive 10 gacha consideration, if the user alone is one of the plurality of users, the consideration required for participation can be kept low. For this reason, even a light user (for example, a beginner of a game) or the like can participate in 10 consecutive gachas together.
It should be noted that the items won by running 10 consecutive gachas together are given according to the selection (nomination) from each user, as in the draft system. At that time, in order to avoid the concentration of selection to a specific item, as will be described later, an item in which at least a part of information related to the selected item is concealed (confidential item) is presented, and an item acquired jointly is displayed. It is a mechanism that is appropriately distributed to each user.
In addition, in order to facilitate understanding of the invention, 10 users will participate in 10 consecutive gachas, and each user will be given one of the 10 selected items. However, the number of participating users is not limited to such ten, and may be other numbers. For example, two users may participate and 5 of the 10 items won may be awarded, respectively, or 2 of the 10 items that 5 users may participate and win. May be given respectively.

The user terminal 300 is a smartphone or the like, for example, and progresses a game (for example, a social game) while accessing the game server 200 via the Internet 900.
For example, the user terminal 300 requests the game server 200 to execute any of the various gacha described above in response to a user operation. When a gacha is executed in the game server 200 (when an item lottery is performed), the user of the user terminal 300 can acquire the winning item. It should be noted that in the 10-game gacha performed by a plurality of users participating, any item can be acquired in accordance with the selection of the participating users, as will be described in detail later. And if the item acquired in this way is an item of a high rank, the user can advance the game in play more advantageously by using the item suitably according to a game situation.

(Outline configuration of information processing device)
A typical information processing apparatus 400 in which the game server 200 and the user terminal 300 according to the embodiment of the present invention are realized will be described.

  As shown in FIG. 2, the information processing apparatus 400 includes a CPU (Central Processing Unit) 401, a ROM (Read Only Memory) 402, a RAM (Random Access Memory) 403, a storage device 404, a display device 405, A communication device 406 and an operation device 407 are provided.

  The CPU 401 controls the overall operation of the information processing apparatus 400 and is connected to each component to exchange control signals and data.

  The ROM 402 records an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, a predetermined program is read into the RAM 403 and execution of the program by the CPU 401 is started.

  The RAM 403 is for temporarily storing data and programs, and holds programs and data read from the storage device 404 and other data necessary for communication.

  The storage device 404 is an SSD (Solid State Drive), a hard disk, or the like, and stores various data. For example, the storage device 404 stores an operating system program, various applications, associated data, and the like necessary for operation control of the entire information processing apparatus 400.

  The display device 405 includes, for example, a display device such as an LCD (Liquid Crystal Display), a VRAM (Video Random Access Memory) that stores image information to be displayed on the display device, and an image process for processing the image information. Part. The image processing unit processes the data read from the storage device 404 or the data processed by the CPU 401, and then stores the data in the VRAM to generate image information.

  The communication device 406 performs wireless communication using a mobile communication network, a wireless local area network (LAN), or the like. Note that the communication device 406 may perform wired communication using a wired LAN or the like. Furthermore, the communication device 406 may perform wireless communication with another information processing apparatus 400 existing in the vicinity by short-range wireless communication such as Bluetooth (registered trademark).

  The operation device 407 is a touch screen, a touch pad, a button, a keyboard, a mouse, or the like, and receives a user operation. Note that a user operation may be received by voice.

  Hereinafter, the configuration and the like of the game server 200 realized in the information processing apparatus 400 will be described with reference to FIGS. When the information processing apparatus 400 is turned on, a program that functions as the game server 200 (the server apparatus according to the present invention) is executed, and the game server 200 according to the present embodiment is realized.

(Outline configuration of game server)
FIG. 3 is a block diagram showing a schematic configuration of the game server 200 according to the present embodiment. As illustrated, the game server 200 includes a reception unit 210, a transmission unit 220, a storage unit 230, and a control unit 240, and supports the progress of the game executed on the user terminal 300.

The receiving unit 210 receives various information transmitted from the user terminal 300 via the Internet 900.
For example, the receiving unit 210 receives, from the user terminal 300, various kinds of operation information during the game and selection information such as selection of items and items on a predetermined selection screen. Note that the selection information includes information requesting execution of the above-described gacha. In addition, when ten consecutive gachas are executed together, the receiving unit 210 also receives selection information for selecting one of the selected items (secret items) sent from the user terminal 300 of the participating user.
The communication device 406 and the like described above can function as such a receiving unit 210.

The transmission unit 220 transmits various information to the user terminal 300 via the Internet 900.
For example, the transmission unit 220 transmits response information according to the operation information and various screens (such as a lottery result screen and an item selection screen described later) according to the gacha to be executed to the user terminal 300.
The communication device 406 and the like described above can function as such a transmission unit 220.

  The storage unit 230 stores various information necessary for the progress control of the game. For example, the storage unit 230 stores user management information 231, item group 232, lottery condition information 233, special lottery condition information 234, selection management information 235, and the like.

The user management information 231 is information for managing the user of each user terminal 300, and includes information as shown in FIG. 4 as an example.
That is, the user management information 231 includes a user ID 231a, a level value 231b, a coin balance 231c, an owned item 231d, a play time 231e, and the like.
The level value 231b is a value indicating the degree of progress of the game for the user (user of the user terminal 300). Instead of such a level value 231b, a game rank or the like may be stored.
Further, the coin balance 231c indicates the balance of coins (which is an example and may be another name) that is the in-game currency acquired by the user. In the following, a case where a predetermined amount of coins is paid (consumed) as consideration for executing gacha will be described. However, even if gacha is executed by paying a consideration different from such in-game currency. Good. For example, when a billing item (in-game gem purchased separately by the user) is used as a price for executing the gacha, the balance of such billing item is also stored in the user management information 231 as appropriate.
The owned item 231d is information (item ID) for identifying an item owned by the user. In principle, the items owned by the user are given from the game server 200 by executing the gacha, but separately from the gacha, according to the progress of the game (for example, by clearing the quest, etc.) Various items may be acquired. In this case, for example, an item ID may be given a branch number so that the acquisition reason can be identified by the branch number.
And the play time 231e is a value which shows the accumulation play time which the user played the game. Note that an average play time per unit period may be stored instead of the accumulated play time.

  Returning to FIG. 3, the item group 232 is information on all items that can be acquired by the user in the game. The item group 232 includes items given to the user by gacha, and such items have a winning probability as described later.

The lottery condition information 233 is information generated by the control unit 240 (a lottery condition generation unit 241 described later) when a gacha is executed.
The lottery condition information 233 includes information as shown in FIG. 5 as an example.
That is, the lottery condition information 233 includes an item ID 233a, a rank 233b, an attribute 233c, a winning probability 233d, and the like.
The rank 233b indicates the grade (class) of items in the game. For example, "Platinum" (platinum rank), "Gold" (gold rank), "Silver" (silver rank) It is prescribed. When a high-ranking platinum-rank item is used in a game (including a character operated by a user), the game can be advanced more advantageously. Further, instead of using such a rank, a rare degree may be used. In that case, for example, “super rare (SR)”, “rare (R)”, and “common (C)” may be defined in descending order of the rare degree.
The attribute 233c indicates the characteristics of the item in the game. For example, the effect (attack power, defense power, etc.) when using the item differs depending on the game situation.
The winning probability 233d indicates the probability that the item will win when the control unit 240 (the lottery unit 242 described later) performs the lottery. The higher the rank (rank 233b), the lower the probability. Has been. In other words, when a gacha is executed, platinum rank items are much harder to win.

Returning to FIG. 3, the special lottery condition information 234 is information that is further generated by the control unit 240 when a 10-run gacha or a 10-run gacha is executed together.
The special lottery condition information 234 includes information as shown in FIG. 6 as an example. That is, like the lottery condition information 233 described above, the special lottery condition information 234 includes the item ID 234a, the rank 234b, the attribute 234c, the winning probability 234d, and the like. The special lottery condition information 234 is different from the lottery condition information 233 in that the special lottery condition information 234 is composed of only platinum rank items.
As described above, in the case of 10 consecutive gachas or 10 consecutive gachas, it is determined that at least one platinum-ranked item is always won. Therefore, in any one of the ten times in these ten consecutive gachas (for example, one selected randomly), the lottery based on the special lottery condition information 234 is performed. ing.

Returning to FIG. 3, the selection management information 235 manages which item (any one of the 10 selected items) has been selected by each participating user when the 10 consecutive gacha has been executed together. This is information generated by the control unit 240 to do this.
In the 10-game gacha together, the 10 selected items are given according to the selection (nomination) from each user as in the draft system. In order to avoid concentrating the selection on a specific item, a secret item (a secret item represented by a silhouette display or partial display described later) in which at least a part of information related to the selected item is concealed is presented. The
In the first round of item selection, each user selects (designates) a desired item, and items selected without duplication (single designation) are given to the selected user. On the other hand, the item selected redundantly (duplicate nomination) is given to one selected user determined by lottery, for example. Even if the secret item is given, at that time (before the secret item is given to all the participating users), the secret is not released (details of the selected item are not revealed). In the second and subsequent rounds, only the user who has not been given the secret item (the user who has been selected redundantly and who has lost the lottery) starts over from the item selection for the remaining secret item. This is repeated until a secret item is given to all participating users.

  The selection management information 235 includes information as shown in FIG. 7 as an example in order to manage item selection (including grant) performed in this way. That is, the selection management information 235 includes the current number of tours 235a, the participating user ID 235b, the assigned category 235c, the first selected item 235d, the second selected item 235e, and the like.

The current number of tours 235a is information indicating how many rounds the selected item (secret item) is selected.
The participating user ID 235b is information for identifying users who have participated in the 10-game gacha. In the example of FIG. 7, a case where 10 users are participating is illustrated.
The assigned category 235c is information indicating whether or not a secret item has been assigned to the user. Note that “ON” is set if it has been assigned, and “OFF” is set if it has not been given (if it has not been given).
The selection item 235d in the first round is information (item ID) for identifying the secret item selected by each user in the first round after ten items are drawn. In the first round, since all the participating users select items, the selected item 235d in the first round is filled with information on the selected secret item without omission.
The selection item 235e in the second round is information for identifying the secret item selected by the user in the second round. In the second round (the same is true for the second and subsequent rounds), only users who have not yet been given an item (users whose assigned category 235c is OFF) select items from the remaining secret items. In the example, only the information of the secret item selected by the three users indicated by “CDE-F234”, “IJK-L567”, and “MNO-P789” is embedded in the selection item 235e of the second round. ing.
In addition, even if the second round is completed, if there are remaining participating users who are not assigned items, the third round is selected, and in this case, the information is managed by the information of the selected item in the third round (not shown). The On the other hand, when all items are selected without overlap in the first round, the secret item is given to all the participating users in the first round, so that the selection of the item is completed, and in the selection item 235e in the second round, No information will be managed.

In addition to this, the storage unit 230 stores various information necessary for processing performed by the control unit 240. For example, the storage unit 230 also stores notification information notified to the user in the game, various event information, and the like.
The RAM 403, the storage device 404, and the like described above can function as such a storage unit 230.

Returning to FIG. 3, the control unit 240 controls the entire game server 200 and supports the progress of the game executed on the user terminal 300.
The control unit 240 includes, for example, a lottery condition generation unit 241, a lottery unit 242, a presentation unit 243, a collection unit 244, an item granting unit 245, and the like. In the following, in order to facilitate understanding of the invention, the presentation unit 243 on the game server 200 side generates various screens (such as a lottery result screen and an item selection screen described later) and presents them to the user terminal 300. However, this is an example, and various screens may be presented on the user terminal 300 by other methods. For example, as will be described later, the game server 200 and the user terminal 300 may cooperate with each other, and finally various screens may be generated on the user terminal 300 side.

When the user terminal 300 requests execution of gacha, the lottery condition generation unit 241 generates lottery condition information that defines the lottery conditions.
For example, the lottery condition generation unit 241 extracts a predetermined number of items from the item group 232 and generates the lottery condition information 233 as shown in FIG. 5 described above. When the composition ratio of each rank in the lottery condition information 233 is determined (for example, platinum rank is 10%, gold rank is 30%, silver rank is 60%, etc.), the lottery condition generation unit 241 Are extracted from the item group 232 by the number corresponding to the composition ratio, and the lottery condition information 233 is generated. At that time, the lottery condition generation unit 241 may appropriately change the method of extracting items from the item group 232 according to the level value of the user who requested execution of the gacha (the level value 231b of the user management information 231).
In addition, when 10 consecutive gachas or execution of 10 consecutive gachas is requested together, the lottery condition generation unit 241 further extracts a predetermined number of platinum rank items from the item group 232 and shows the above-described FIG. Such special lottery condition information 234 is generated.

The lottery unit 242 executes a lottery game based on lottery conditions in which the winning probability of each item is defined.
That is, the lottery unit 242 randomly draws items based on the lottery condition information 233 generated by the lottery condition generation unit 241.
For example, when execution of a single shot gacha is requested, the lottery unit 242 performs lottery of one item based on the lottery condition information 233.
In addition, when execution of 10 consecutive gachas or 10 consecutive gachas is requested together, in 9 out of 10 times, the lottery unit 242 selects one item (total 9) based on the lottery condition information 233. Lottery items). Then, in one out of ten times, the lottery unit 242 performs lottery of one item based on the special lottery condition information 234.

The presentation unit 243 generates various screens and presents them on the user terminal 300.
For example, the presentation unit 243 allows the participating users to select any of the winning items (secret items) in a list screen of various gachas, a screen for appropriately informing a lottery result by gachas, and a group of 10 consecutive gachas. Are displayed on the user terminal 300 through the transmission unit 220.

Specifically, the presentation unit 243 generates a gacha list screen 510 as illustrated in FIG. 8 and presents it on the user terminal 300.
The gacha list screen 510 includes a request button 511 for requesting execution of a single shot gacha, a request button 512 for requesting execution of a 10-line gacha, and a request for requesting execution of 10-line gacha together. Button 513 is included. When any of the request buttons 511 to 513 is pressed (touched or clicked) by the user in a state where the gacha list screen 510 is presented on the user terminal 300, the corresponding gacha is executed by the game server 200. Required.

In addition, when the request button 513 is pressed and execution of ten consecutive gachas is requested together, for example, a waiting ID or the like can be input, and a plurality of users who are informed of the waiting ID or the like are the same. Everyone can participate in 10 consecutive gacha.
In addition to this, when everyone is requested to execute 10 consecutive gachas, they will be transferred to the waiting lobby so that users who match in the waiting lobby can participate in the 10 consecutive gachas together. May be. Furthermore, when everyone is required to execute 10 consecutive gachas, a dedicated page is allocated, and users can distribute a link to the dedicated page by e-mail or short message. From the distributed link, Each user may be allowed to participate in 10 consecutive gachas with the same everyone.
Then, by gathering 10 users who participate, 10 consecutive gachas are executed together.

In addition, when the request button 512 is pressed on the gacha list screen 510 and execution of 10 consecutive gachas is requested, the lottery unit 242 draws 10 items. And the presentation part 243 produces | generates the lottery result screen 520 as shown in FIG. 9, and shows it to the user terminal 300 which requested | required gacha.
On the lottery result screen 520, the user can confirm the 10 items won in the 10-game gacha.
When a request button 511 is pressed on the gacha list screen 510 and execution of a single shot gacha is requested, the lottery unit 242 performs lottery of one item. Similarly, the presenting unit 243 generates a lottery result screen in which one winning item can be confirmed and presents it to the user terminal 300 that has requested the gacha.

Further, as described above, when 10 users who participate in the 10-game gacha gather together, the lottery unit 242 draws 10 items. At that time, the presenting unit 243 changes the selected 10 items to secret items in which at least part of the information related to the items is concealed. And the presentation part 243 produces | generates the item selection screen which allows the user who participated to choose any of such a secret item, and shows it to a participating user (each user who participates in 10 consecutive gachas).
For example, the presentation unit 243 generates an item selection screen 530 as shown in FIGS. 10A and 10B and presents it to the participating users. The item selection screen 530 in FIG. 10A illustrates a case where a secret item in which the selected item is concealed in a silhouette display is presented. In addition, the item selection screen 530 in FIG. 10B illustrates a case where a secret item in which the selected item is concealed in a partial display (for example, a random partial display) is presented. In addition, the item selection screen 530 in FIGS. 10A and 10B illustrates an item selection screen in the first round, and any secret item is presented to be selectable. On the other hand, if it is the item selection screen in the second round and after, the assigned secret items are not selectable due to, for example, gray display, and only the secret items that are not given are presented to be selectable. Will be.
Moreover, the aspect of these secret items is an example, and you may show the secret item which concealed at least one part of the information regarding the item elected by the other method. For example, the presentation unit 243 may present a secret item in which the selected item is concealed in a mosaic display. In addition, the presentation unit 243 may present a secret item that is partially displayed by concealing only the feature part of the selected item. In addition, the presentation unit 243 does not display the appearance of the selected item at all, and only displays the attribute of the item (for example, the fire attribute, the lightning attribute, the light attribute, the water attribute, etc.) by text display. A secret item may be presented.
A plurality of types of secret items may be presented together. For example, in the same item selection screen, the secret item displayed in silhouette display, the secret item partially displayed, the secret item displayed in mosaic, and the like may be presented together.

In addition, in the item selection screens 530 of FIGS. 10A and 10B, the case where all the selected items are changed to secret items is illustrated, but only a part of the selected items are changed to secret items. May be.
For example, the presenting unit 243 may change only items of the gold rank or higher (gold rank and platinum rank) to the secret items, and the silver rank items may be presented as they are without being concealed.

In addition, as shown in either of FIGS. 10A and 10B, the same item selection screen 530 is not presented to any participating user, but the item selection screen to be presented according to the user level value or the like. The secret item and the degree of secrecy may be presented differently.
For example, for a heavy user whose level value (level value 231b of the user management information 231) is larger than a reference value, the presentation unit 243 may change all the selected items to secret items and make it difficult to narrow down the target. Good. On the other hand, for a beginner user whose level value is less than a certain value, the presentation unit 243 may change only items of the gold rank or higher to secret items to make it easier to narrow down the aim (reference value> Constant value).
Furthermore, if the user is a heavy user, for example, when a secret item with a relatively low level of secrecy such as a silhouette display is presented, it is often possible to identify what the secret item is. Therefore, the presentation unit 243 may present a secret item with a relatively high degree of secrecy such as mosaic display or random partial display to a heavy user. On the other hand, for the beginner user, the presentation unit 243 may present a secret item with a relatively low level of secrecy so as to assist in prediction.
Conversely, an item selection screen may be generated based on one of the participating users, and the same item selection screen may be presented to other participating users. For example, the presentation unit 243 specifies the lowest (or higher) level value among the level values of the participating users, determines the secret item corresponding to the level value, and the degree of secrecy, and selects the item. Generate a screen. In addition, the item selection screen may be generated by specifying the median level value among the participating users.
And the presentation part 243 presents the item selection screen produced | generated in this way to the user terminal 300 of each participating user.

Returning to FIG. 3, after the presentation unit 243 presents the item selection screen 530 as shown in FIGS. 10A and 10B to the participating user, the collection unit 244 displays the selection information of the item selected by the participating user. collect.
That is, the collection unit 244 collects, through the reception unit 210, selection information indicating the confidential item selected by each participating user among the confidential items presented on the item selection screen 530.
In addition, as described above, in a state where the item selection screen in which only a part of the selected item is changed to a secret item is presented to the participating user, and the participating user selects an item that is not concealed, The collection unit 244 collects selection information indicating such an item that is not concealed.

The item assigning unit 245 assigns each selected secret item to any selected participating user according to the selection information collected by the collecting unit 244. For example, according to the collected selection information, the item granting unit 245 selects the first-round selection item 235d or the second-round selection item 235e according to the corresponding user (participating user ID) in the above-described selection management information 235 in FIG. Etc. (more specifically, the information on the secret item selected by the participating user is embedded in the current tour number 235a selected item). And when collection of selection information is completed from all the participating users (all the participating users to whom no item has been assigned at that time), the item granting unit 245 grants the selected secret item to the selected user without duplication. To do. In addition, when assigning a secret item to a selected user, the assigned section 235c of the corresponding user (participating user ID) in the selection management information 235 described above is updated to ON, and the corresponding in the user management information 231 described above. The identification information (item ID) of the assigned item is added to the user's owned item 231d.
On the other hand, for the secret item selected in duplicate, the item granting unit 245 determines one selected user, for example, by lottery from among the selected users who have selected the same secret item, and conceals it from the selected user. Grant an item. It should be noted that the item granting unit 245 does not release the secrecy even if the secret item is given (the details of the item are not clarified) before giving the item to all the participating users. .

  The presenting unit 243, the collecting unit 244, and the item granting unit 245 are repeated while increasing the number of tours until any secret item is given to all participating users. Then, when the assignment of the secret item is finished for all the participating users, the item granting unit 245 releases the secrecy of the secret item assigned to each participating user, and reveals the details of the item. The target to be revealed may be for all the participating users or only for the given participating users.

In addition to this, the control unit 240 also collects compensation for the execution of the gacha. That is, the control unit 240 performs processing such as subtracting the amount of consideration from the corresponding user's coin balance 231c in the user management information 231.
The above-described CPU 401 or the like can function as the control unit 240 having such a configuration.

  Hereinafter, the configuration and the like of the user terminal 300 realized in the information processing apparatus 400 will be described with reference to FIGS. When the information processing apparatus 400 is turned on, a program that functions as the user terminal 300 (terminal apparatus according to the present invention) is executed, and the user terminal 300 according to the present embodiment is realized.

(Outline configuration of user terminal)
FIG. 11 is a block diagram illustrating a schematic configuration of the user terminal 300 according to the present embodiment. As illustrated, the user terminal 300 includes an operation reception unit 310, a transmission / reception unit 320, a storage unit 330, a control unit 340, and a display unit 350. For example, the user terminal 300 can appropriately communicate with the game server 200 while playing a game. To proceed.

The operation reception unit 310 receives various operations from the user. For example, the operation reception unit 310 receives an operation from the user based on information obtained from a touch screen or the like.
The operation device 407 and the like described above can function as such an operation reception unit 310.

The transmission / reception unit 320 accesses the game server 200 via the Internet 900 and transmits / receives information necessary for the progress of the game.
For example, the transmission / reception unit 320 receives various screens transmitted from the game server 200 (the gacha list screen 510, the lottery result screen 520, the item selection screen 530, etc. described above).
In addition, the transmission / reception unit 320 transmits operation information and selection information for various screens to the game server 200.
The communication device 406 and the like described above can function as such a transmission / reception unit 320.

  The storage unit 330 stores, for example, game management information 331 and the like.

For example, as shown in FIG. 12, the game management information 331 includes a user ID 331a, a level value 331b, a coin balance 331c, an owned item 331d, a play time 331e, and the like. That is, the same information as the above-described user management information 231 is also managed on the user terminal 300 side.
The information stored in the game management information 331 is appropriately synchronized with the user management information 231 stored on the game server 200 side, as will be described later.

In addition to this, the storage unit 330 also stores image data such as items and characters in the game. Further, as will be described later, when the user terminal 300 (screen generation unit 342) generates the item selection screen 530 and the like, the storage unit 330 also stores various icon images and the like.
The storage device 404 and the like described above can function as such a storage unit 330.

  Returning to FIG. 11, the control unit 340 controls the entire user terminal 300. The control unit 340 includes, for example, a game progression unit 341, a screen generation unit 342, and the like.

The game progression unit 341 executes the game, and advances the game according to the user operation received by the operation reception unit 310. At that time, the game progression unit 341 transmits / receives data to / from the game server 200 through the transmission / reception unit 320, for example, information managed by the game management information 331 and information managed by the user management information 231 ( The corresponding user information).
In addition, when any of the request buttons 511 to 513 is pressed by the user while the above-described gacha list screen 510 of FIG. 8 is displayed on the display unit 350, the game progress unit 341 causes the game server 200 to gacha. Request execution.
Further, when any of the secret items is selected by the user while the item selection screen 530 as shown in FIGS. 10A and 10B is displayed on the display unit 350, the game progression unit 341 The selection information indicating the user ID of the selected user and the selected secret item is transmitted to the game server 200 through the transmission / reception unit 320.

The screen generation unit 342 generates a game screen or the like. That is, various screens for the user to advance the game are generated.
As described above, the gacha list screen 510, the lottery result screen 520, and the item selection screen 530 are generated on the game server 200 side (presentation unit 243), but instead of the presentation unit 243, the screen The generation unit 342 may generate these screens.
In that case, only the element data handled as a variable is sent from the game server 200 side to the user terminal 300, and when the element data is received through the transmission / reception unit 320, the screen generation unit 342 displays the element data and the storage unit 330. Various screens are generated based on the information stored in the screen. As an example, a case where the item selection screen 530 is generated will be described. From the game server 200 side to the user terminal 300, information on a lottery result by the lottery unit 242 (for example, item ID, rank, and , Attributes and other information). Then, the screen generation unit 342 changes the selected item to a secret item concealed in the silhouette display, and generates an item selection screen 530 as illustrated in FIG. Further, the screen generation unit 342 changes the selected item to a secret item that is concealed by partial display (for example, random partial display), and generates an item selection screen 530 as illustrated in FIG. In addition, similarly to the presentation unit 243, the screen generation unit 342 may generate an item selection screen that presents a secret item that conceals at least a part of information related to an item won by another method.

In addition to this, the control unit 340 appropriately executes processing necessary for the progress of the game, such as superimposing notification information and the like sent from the game server 200 on the game screen and displaying them on the display unit 350.
The above-described CPU 401 and the like can function as the control unit 340 having such a configuration.

The display unit 350 displays the game screen generated by the screen generation unit 342. The display unit 350 also displays various screens (such as a gacha list screen 510, a lottery result screen 520, and an item selection screen 530) sent from the game server 200. As described above, these various screens may be generated on the user terminal 300 side, and even in that case, the display unit 350 displays the various screens generated by the screen generation unit 342.
Note that the display device 405 and the like described above can function as such a display unit 350.

(Game server operation)
The operation of the game server 200 configured as shown in FIG. 3 will be described below with reference to FIG. Note that the game server 200 controls the overall progress of the game executed on the user terminal 300, and among them, the most characteristic item distribution process in the ten consecutive gacha will be described.
FIG. 13 is a flowchart showing a flow of item distribution processing according to the present embodiment. This item allocation process is a process in the case where ten consecutive gachas are executed together in the game server 200. For example, in the plurality of user terminals 300 on which the gacha list screen 510 as shown in FIG. Each of the buttons 513 is pressed, and the process starts when ten users who participate in the ten consecutive gacha gather.

First, the game server 200 generates lottery condition information (step S11).
That is, the control unit 240 (lottery condition generation unit 241) extracts the items of each rank from the item group 232 by the number corresponding to the composition ratio, and generates lottery condition information 233 as shown in FIG. Furthermore, the control unit 240 extracts a predetermined number of platinum rank items from the item group 232, and generates special lottery condition information 234 as shown in FIG.

The game server 200 performs item lottery based on the lottery condition information (step S12).
That is, the control unit 240 (lottery unit 242) randomly draws items based on the lottery condition information 233 generated in step S11.
For example, the control unit 240 performs lottery for each item (a total of nine items) based on the lottery condition information 233. Then, in one out of ten times, the control unit 240 performs lottery for one item based on the special lottery condition information 234.

The game server 200 changes the selected item to a secret item (step S13).
That is, for example, the control unit 240 (presentation unit 243) changes the selected item to a concealed item concealed by silhouette display. In addition to this, the control unit 240 may change the selected item to a secret item concealed by partial display, or may be changed to a secret item concealed by mosaic display. At that time, each of the selected items may be changed into a plurality of types of secret items. That is, the control unit 240 changes a selected item to a concealed item concealed in the silhouette display, and changes another item to a concealed item concealed in the mosaic display.
Moreover, the control part 240 may change all the selected items into a confidential item, and may change only a part of selected items into a confidential item.

The game server 200 generates an item selection screen and presents it to the participating users (step S14).
That is, for example, the control unit 240 (presentation unit 243) generates an item selection screen 530 as shown in FIGS. 10A and 10B and presents it to the participating users. In addition, the item selection screen 530 in FIGS. 10A and 10B illustrates an item selection screen in the first round, and any secret item is presented to be selectable. On the other hand, if it is the item selection screen in the second round and after, the assigned secret items are not selectable due to, for example, gray display, and only the secret items that are not given are presented to be selectable. Will be.

The game server 200 collects selection information (step S15).
That is, the control unit 240 (collection unit 244) presents the item selection screen 530 as shown in FIGS. 10 (a) and 10 (b) to the participating user in step S14, and then displays the item selected by the participating user. Collect selection information.
That is, the control unit 240 collects, through the reception unit 210, selection information indicating the confidential item selected by each participating user among the confidential items presented on the item selection screen 530.

The game server 200 gives an item (step S16).
That is, the control part 240 (item provision part 245) assign | provides each of the selected confidential items to any selected participating user according to the selection information collected in said step S15. For example, in accordance with the collected selection information, the control unit 240 assigns the participating user to the first selection item 235d, the second selection item 235e, and the like corresponding to the corresponding user (participation user ID) in the selection management information 235. The information of the secret item selected by will be filled. When the collection of selection information from all participating users (all participating users to which no item has been assigned at that time) is finished, the control unit 240 assigns the selected confidential item to the selected user without duplication. . In addition, when assigning a secret item to a selected user, the assigned section 235c of the corresponding user (participating user ID) in the selection management information 235 is updated to ON, and the item owned by the corresponding user in the user management information 231 The identification information (item ID) of the assigned item is added to 231d.
On the other hand, for the secret item selected in duplicate, the control unit 240 determines one selected user by, for example, lottery from among the selected users who have selected the same secret item, and the secret user is notified to the selected user. Is granted. In addition, the control part 240 shall not cancel a secrecy (it does not clarify the detail of the item), even if a secrecy item is provided, before giving an item with respect to all the users who participated.

The game server 200 determines whether or not the item has been assigned to all participating users (step S17).
When it is determined that the item has not been assigned (step S17; No), the game server 200 returns the process to step S14 described above.

  On the other hand, when it is determined that the item has been added (step S17; Yes), the game server 200 ends the item distribution process.

  In such an item distribution process, as in the draft system, an item won in accordance with a selection (nomination) from each participating user is given. At that time, since the selected item is presented as a secret item, it is possible to avoid a situation where the selection concentrates on a specific item, and it can be expected that the selection is dispersed to some extent. In that case, each participating user is easily given the secret item that he / she has selected. Further, even if such a secret item is selected and an item different from the expectation is given as a result, since it is an item selected by itself, it is easy to accept such a result.

  As a result, items acquired jointly by a plurality of users can be appropriately distributed to each user.

(Other embodiments)
In the above embodiment, in the selection of items when everyone executes 10 consecutive gachas, the case where duplicated items are given to one person determined by lottery or the like has been described. You may make it give to the participating user determined based on whether an item is used.
For example, the item granting unit 245 estimates the possibility that each participating user who has selected the item will use the item for the item selected in duplicate. And the item provision part 245 may provide the item to the participating user with the highest possibility.
In this case, even if the selection is duplicated, the item can be easily given to a user who can use it effectively, and the item can be distributed to the right place.

In the above embodiment, a case has been described in which the degree of secrecy of the secrecy icon is presented in accordance with the level value of the participating user, etc., but the ownership rate that the participating user already owns a plurality of items is obtained. The degree of secrecy of the secret item may be varied depending on the ownership rate. For example, for a user with a high ownership rate of a plurality of lottery items, if the level of secrecy of a secrecy item is high, there is a high possibility that an item that overlaps with an already owned item will be selected. The secret level of the secret item is lowered and presented so that the user can easily select the item with his / her strategy. On the other hand, for a user with a low ownership rate of a plurality of lottery items, since the possibility of selecting an item that overlaps with an already owned item is low, the presentation unit 243 presents the confidential item with an increased degree of confidentiality. .
Further, in these cases, the degree of secrecy of such a secrecy icon may be lowered with the passage of time or the like, and it may be gradually clarified what the item is.
For example, the presenting unit 243 sequentially decreases the degree of secrecy of the secrecy item as the presentation time or the number of repetitions of the presentation (the number of visits) proceeds. And the item provision part 245 may be made to give to the participating user selected first only in such a secret item.
In this case, as the presentation time and the number of tours elapse, the details of the secret item will become clear, but since it is a first-come-first-served basis, the user's judgment and instantaneous power etc. will be tested, making it more interesting Can be increased.

In the above embodiment, the case where only a part of the selected item is changed to a secret item according to the level value or the like of the participating user has been described, but the selected item depends on whether or not the participating user already owns it. It may be determined whether or not to change to a secret item.
For example, in each participating user, the presentation unit 243 may prevent an item already owned by the participating user from being changed to a secret item.
That is, the items owned by the user are presented without secrecy, and the determination is left to the user. For example, a user who does not need to own a plurality of the same item will select another item, while a user who wants to use the same item for composition or the like will select that item.
Moreover, you may restrict | limit only the item which all the participating users have to present without concealing among the selected items. That is, the presentation unit 243 does not change the item to a secret item only for items already owned by the participating users.
In these cases, it is easy for the user to select an item freely by not intentionally concealing the owned item.

In the above embodiment, a case has been described in which the game server 200 manages a process in which a participating user selects a confidential item or the like among the selected items using the selection management information 235. However, the user terminal 300 side of the participating user Thus, the process of selecting a secret item or the like may be managed.
For example, the user terminal 300 of the participating user stores information similar to the selection management information 235, and information such as the secret item selected by the participating user at each user terminal 300 via the game server 200. Try to send each other. At that time, as described above, the screen generation unit 342 of the user terminal 300 changes the selected item to a concealed item concealed by a silhouette display or the like, and an item selection screen 530 as shown in FIG. It will be generated and presented to participating users. Then, after the items to be given to all participating users are determined, the correspondence information between the participating users and the items is transmitted to the game server 200 from each user terminal 300 (or the representative user terminal 300), and finally, A corresponding item is given to the participating user from the game server 200.
Further, the user terminal 300 may perform such various gachas including ten consecutive gachas while communicating with the game server 200 on an application such as a browser, and is installed in the user terminal 300. Various gachas may be performed by executing the game application. In particular, when a game application is installed in the user terminal 300, the user terminal 300 may be able to perform various gachas independently. At that time, only when the ten consecutive gachas are executed together, the game server 200 may be accessed to recruit other participating users. When the user terminal 300 has a short-range wireless communication function such as Bluetooth (registered trademark), even if the ten-unit gacha is executed together, the short-range wireless communication function is not performed via the game server 200. Through this, other participating users may be recruited.
Also in these cases, items acquired jointly by a plurality of users can be appropriately distributed to each user.

In the above-described embodiment, a case has been described in which ten consecutive gachas are performed ten times in succession as in the case of ten consecutive gachas. You may go.
In that case, the number of users who can participate is changed as appropriate in accordance with the number of times gacha is continuously performed.

  In the above embodiment, the case where the dedicated game server 200 or the user terminal 300 is used has been described. However, an operation program that defines the operation of the game server 200 or the user terminal 300 is used as an existing personal computer, information terminal device, It is possible to make the personal computer function as the game server 200 or the user terminal 300 by applying to the above.

  In addition, such a program distribution method is arbitrary, for example, a computer-readable medium such as a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disc), an MO (Magneto Optical Disc), or a memory card. It may be stored in a recording medium and distributed, or distributed via a communication network such as the Internet.

(Summary)
A game system according to a first aspect of the present invention is a game system that provides a lottery game in which a plurality of users participate jointly, and includes a lottery unit, a presentation unit, a collection unit, and a grant unit. .

When the lottery game is started, the lottery unit draws a plurality of items. The presenting unit changes a part or all of a plurality of items lottery by the lottery unit to a secret item that conceals at least a part of information related to the item, and a plurality of items including the secret item are changed to a plurality of users. To present.
The collection unit collects selection information of items selected by a plurality of users from among a plurality of items including the secret item presented by the presentation unit. Then, the assigning unit assigns each selected item to any selected user according to the selection information collected by the collecting unit.

As described above, the plurality of items selected by the lottery unit are presented to each user in a state in which some or all of the items are changed to confidential items. Each user can freely select an item from the presented items while predicting what the secret item is. At that time, since each user's speculation is different, it is possible to avoid a situation in which the selection is concentrated on one item, and it can be expected that the selection is dispersed to some extent. In that case, it becomes easy to give each user the item which he selected. Further, even when a secret item is selected and an item different from the expectation is given as a result, since it is an item selected by the user, such a result is easily accepted.
As a result, items acquired jointly by a plurality of users can be appropriately distributed to each user.

In the above game system, the presenting unit presents the plurality of items in a state in which selected items cannot be selected, and the collecting unit selects information from a plurality of users to whom no item is imparted. The granting unit gives the selected item among the plurality of items without duplication to the user who selected the item, and for the item selected duplicately, any of the items selected You may give to this user.
That is, the item selected without duplication is given to the selected user, and the item selected with duplication is given to, for example, one selected user determined by lottery or the like.
Also in this case, since the secret item is included in the presented item, the situation where the selection is concentrated on one item can be avoided, and the selection is distributed to some extent, so that each user selects the user himself / herself. It becomes easy to give an item.

Moreover, in the said game system, you may repeat until a presentation part, a collection part, and a provision part are provided with one of the items with respect to all the some users.
That is, as in the draft system, in the first round, each user selects (designates) a desired item, and the items selected without duplication (single designation) are given to the selected user and are duplicated ( The item that is designated as a duplicate is given to one selected user determined by lottery, for example. Even if a secret item is given, the secret is not broken at this point (details of the item are not clarified). From the second round onward, only the user who has missed the lottery (the user who has not been given an item) repeats the selection of items for the remaining items.
Then, when the distribution of the items is finished, the secrecy of the secret item is canceled, and the details of the item are made clear. The target to be revealed may be for each user or only the assigned user.
In this case, if the secret item remains even after the second round, the secret item may be a high-rank item, so that the expectation of the user who has not yet been granted can be maintained. .

In the above game system, the granting unit estimates the possibility that each user who has selected the item will use the item for each item selected in duplicate, and the item is given to the user who has the highest possibility. May be given.
In this case, even if the selection is duplicated, the item can be easily given to a user who can use it effectively, and the item can be distributed to the right place.

Moreover, in the said game system, a presentation part reduces the degree of secrecy about a secrecy item sequentially as presentation time or the number of repetitions of presentation advances, and a grant part is the user who selected first only for a secrecy item. You may give to.
In this case, the details of the secret item will become clear as time elapses, but since it is a first-come-first-served basis, the user's judgment, instantaneous power, etc. will be tested, which may further enhance interest. it can.

Moreover, in the said game system, the presentation part may vary the item changed to a secrecy item, and the secrecy degree of a secrecy item according to the progress degree of the game in each of several users. For example, if it is a heavy user, if the level of concealment of a concealed item is low (for example, a silhouette display or a partial display of a characteristic part), it is often possible to specify what the concealment item is. Increase the degree (for example, mosaic display or random partial display). On the other hand, if it is a beginner user, the degree of secrecy is lowered so as to assist in prediction.
In this case, by equalizing the ability to identify (imagine) a secret item among users, fairness can be further improved even when an item is selected.

Moreover, in the said game system, a presentation part may make it not change into the confidential item about the item which the user already has in each of several users.
That is, the items owned by the user are presented without secrecy, and the determination is left to the user. For example, a user who does not need to own a plurality of the same item will select another item, while a user who wants to use the same item for composition or the like will select that item.
In this case, it is easy for the user to select an item freely by not intentionally concealing the owned item.

Further, in the above game system, the presenting unit obtains the ownership rate of the plurality of users who already own the plurality of items selected by the lottery unit, and varies the degree of confidentiality of the confidential item according to the ownership rate. May be. For example, for users with a high ownership rate of a plurality of lottery items, if the confidentiality level of the confidential item is high, the possibility of selecting an item that overlaps with the owned item increases. To make it easier for users to select items with their strategies. On the other hand, a user with a low ownership rate of a plurality of lottery items is presented with an increased degree of secrecy of the secrecy item because there is a low possibility that an item that overlaps with an already owned item is selected.
In this case, it is possible to appropriately change how the secret item is displayed according to the user's possession status.

  An item granting method according to a second aspect of the present invention is an item granting method in a server device that provides a lottery game in which a plurality of users participate jointly, and a lottery step, a presentation step, a collection step, and an grant Has steps.

  That is, the item granting method according to the second aspect can appropriately distribute items acquired jointly by a plurality of users to each user, as in the game system according to the first aspect.

  The program according to the third aspect of the present invention causes a computer that provides a lottery game in which a plurality of users participate in collaboration to function as a lottery unit, a presentation unit, a collection unit, and a grant unit.
