JP7429735B2 - Lottery system, lottery method, and program - Google Patents

Description

The present invention relates to a lottery system, lottery method, and program that provide a lottery service for shipping items specified by lottery to users.

Techniques have been proposed for identifying items in response to a lottery request from a user and shipping the identified items. For example, Patent Document 1 discloses a technology in which ``...a lottery is held on a network to recruit consumers... prizes and prizes are shipped to the winning consumers...''.

In addition, a lottery service is also provided that allows users to participate in a lottery by paying a participation fee in cash, electronic money, or various points, and in which winning items are identified from character goods, etc. that are eligible for the lottery. . In such lottery services, there are often so-called "no-lost" lots, where one of the items is guaranteed to win.

Among such lottery services, there are those in which the winning item is an electronic item and does not involve shipping (see Patent Document 2), and there are also services in which the actual item is shipped.

In lottery services that ship actual items, the lottery is limited to a certain period of time, and after the end of that period, the number of items to be shipped to the winning users has been determined before manufacturing of the items begins. Some try to maintain the rarity of items.

Further, even when items that have already been manufactured are selected for lottery, it takes time to order and ship the items. Therefore, in most cases, a certain amount of time is required from the time the lottery is held until the item is shipped.

Japanese Patent Application Publication No. 2005-043982 Japanese Patent Application Publication No. 2020-108596

In lottery services such as those described above, if the lottery is repeated several times, the same item may be obtained twice. In particular, if the user repeatedly draws lots when it is difficult to win an item that the user wants, a large number of items that are less likely to be desired may also be won.

Depending on the user, some of the items that have been won multiple times and have low desirability may be disposed of on the second-hand market. In this case, there is a risk that the rarity of the item will decrease.

Therefore, in the above-mentioned lottery service, there is a need for a technique suitable for appropriately processing items that are least likely to be desired by users among the items specified through the lottery.

The present invention solves the above-mentioned problems, and aims to provide a lottery system, a lottery method, and a program that allow a user to cancel shipping of items specified by lottery.

In order to solve the above problems, the lottery system according to the present invention,
In response to a lottery request from a user, specify the item to be shipped to the user,
causing specific information related to the identified item to be presented to the user;
accepting a cancellation request related to the specified item from the user until a deadline set for the specified item;
If the cancellation request is accepted by the set deadline, a setting is made to the effect that an exchange price corresponding to the specified item should be given to the user instead of canceling shipping of the specified item.

According to the present invention, it is possible to provide a lottery system, a lottery method, and a program that allow a user to cancel shipping of items specified by lottery.

Embodiments of the present invention will be described below. Note that this embodiment is for explanation purposes only, and does not limit the scope of the present invention. Therefore, those skilled in the art can adopt embodiments in which each or all of these elements are replaced with equivalents, and these embodiments are also included within the scope of the present invention.

(Configuration of lottery system)
In the lottery system according to this embodiment, one or more servers cooperate with a terminal such as a smartphone, a tablet computer, or a personal computer to provide a lottery service to the user of the terminal.

The server and terminal of this embodiment are generally realized by having a computer execute a program, but it is also possible to have a dedicated electronic circuit execute the processing. In addition, as an intermediate form between computers and dedicated electronic circuits, technologies such as FPGA (Field Programmable Gate Array), which compile programs into electronic circuit design scripts and dynamically configure electronic circuits based on the design scripts, are being used. By applying this, it is also possible to configure the server and terminal of this embodiment.

The server according to this embodiment is realized by one or more server computers that manage terminals receiving the lottery service executing each function realized by one or more server programs.

The terminal according to this embodiment is a terminal computer that realizes a smartphone or the like, and is realized by a lottery service provider or operator downloading a terminal program distributed by a distribution server.

As the terminal program, one equivalent to a so-called "app" can be employed.

In addition, a general browser can be used as the terminal program, and a script program that runs on the browser can also be used as the terminal program.

In these cases, the application or browser running on the terminal computer becomes an interface for providing lottery services to users by communicating with the server of the lottery system that functions as an application server or a web server.

Generally, programs executed on server computers and terminal computers are stored on compact disks, flexible disks, hard disks, magneto-optical disks, digital video disks, magnetic tapes, ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable ROM), and flash memory. , a computer-readable non-transitory information storage medium such as a semiconductor memory. This information recording medium can also be distributed and sold independently of the server computer and terminal computer.

In server computers and terminal computers, programs recorded on non-transitory information recording media such as flash memory or hard disks are read into RAM (Random Access Memory), which is a temporary storage device, and then read out. , the CPU (Central Processing Unit) executes the instructions included in the read program. However, in architectures that allow ROM and RAM to be mapped into a single memory space for execution, the CPU directly reads and executes instructions contained in programs stored in ROM.

Furthermore, server programs and terminal programs can be transferred from a distribution server managed by an operator to a server computer via a transitory transmission medium such as a computer communication network, independently of the computer on which the program is executed. It can be distributed and sold to terminal computers, etc.

Note that when the server that provides the lottery service is composed of a plurality of computers, the programs running on each computer are a plurality of different server programs that have different functions and work together. Therefore, the combination of the plurality of programs can be considered as a system program for realizing a lottery system.

(overall structure)
FIG. 1 is an explanatory diagram showing the cooperation of devices that realize the lottery system. This will be explained below with reference to this figure.

In the lottery system 101 shown in this figure, a server 102 and a terminal 103 are communicably connected via a computer communication network 104 such as the Internet.

In the lottery system 101, a user using a terminal 103 sends a lottery request to the server 102 via the terminal 103. The server 102 executes a lottery, and the items identified as a result, that is, the winning items, are manufactured and shipped to the user at a later date, if necessary.

Note that the term "item" in this application includes not only "products" that are intended to be sold individually, but also "articles" and "objects" that are not intended to be sold individually.

"Goods" and "Things" include items such as novelty goods that are distributed free of charge for advertising purposes, or that can be entered into a lottery with the condition of purchasing paid products or services, and that are awarded upon winning.・In addition to goods, users can participate in the lottery for a fee, as shown as an example in the embodiment below, but it is not possible for users to directly purchase the goods or goods they wish to win. This includes cases where

Now, in this figure, the server 102 is shown as providing a lottery service with one server computer, but multiple server computers divided by function can work together to provide a lottery service. It is also possible to configure it as follows.

For example, there is a lottery computer that executes processing related to the lottery and the processing of winning items, a database computer that records user information and lottery results, a manufacturing control computer that manages the manufacturing of items according to the lottery results, and a manufacturing control computer that performs manufacturing management of items according to the lottery results. It is possible to implement separate functions, such as a shipping computer that manages shipping of completed items.

FIG. 2 is an explanatory diagram showing the relationship between each part in the lottery system. FIG. 3 is a session diagram showing interactions in the lottery system from when a user makes a lottery request until the shipping of the winning item is canceled. FIG. 4 is a session diagram showing interactions in the lottery system from when a user makes a lottery request until the processing related to shipping of the winning item begins. The following description will be made with reference to these figures.

As shown in this figure, the lottery system 101 includes a specifying section 111, a presentation section 112, a reception section 113, and an exchange section 114. Furthermore, the output unit 115 can be included as an optional element.

Here, the specifying unit 111 specifies the item to be shipped to the user, that is, the winning item, in response to a lottery request from the user. Typically, when a user operates the terminal 103 to request a lottery (201), the terminal 103 transmits a lottery request to the server 102 (202).

By receiving the lottery request (202), the server 102 accepts the user's lottery request, and the server 102 executes the lottery in response to this lottery request. Typically, information regarding the user and information about the winning item to be shipped to the user are recorded in a lottery database that manages lottery items (203).

On the other hand, the presentation unit 112 causes the user to be presented with specific information regarding the specified item. That is, the presentation unit 112 controls other devices or itself to present the specific information to the user by presenting it on various display devices. Typically, the server 102 transmits a lottery response indicating the winning item to the terminal 103 (204), and the terminal 103 displays specific information regarding the winning item on the screen according to the received lottery response (204). 205), to be presented to the user. In addition, the server 102 can be configured to send a screen control signal to a display device connected to the server 102 by wire or wirelessly, and the display device displays specific information on the screen. Through these processes, the presentation unit 112 causes the specific information to be presented to the user.

Furthermore, the reception unit 113 accepts cancellation requests related to the specified item from the user until the deadline set for the specified item. Typically, when a user who believes that the winning item indicated by the specific information is unnecessary operates the terminal 103 to request cancellation (206), the terminal 103 sends the request to the server to cancel the shipping of the winning item. Send to 102 (207).

If the cancellation request is received by the set deadline (see Figure 3), the exchange unit 114 will grant the user an exchange price corresponding to the specified item instead of canceling the shipment of the specified item. Set what should be done.

That is, when the server 102 receives the cancellation request, it means that the server 102 has accepted the cancellation request, and the server 102 logically deletes or physically deletes the information that the winning item should be shipped to the user from the lottery database. etc., and the shipping of the winning items is canceled (208).

In addition, when various points are adopted as exchange consideration, the server 102 records in the point database that the points corresponding to the exchange consideration should be added to the total points owned by the user, thereby increasing the exchange consideration. Grant (209).

Here, in a mode in which a user requests payment of lottery consideration in order to make a lottery request, that is, in a mode in which the user participates in the lottery for a fee, the user can use the exchange consideration obtained here as a new lottery fee for a new lottery request. It can be made applicable to payment of lottery consideration.

For example, if a user is required to pay 500 yen for one lottery, and they have received 300 points as exchange consideration, by converting the 300 points into 300 yen and applying it, the user can pay 200 yen. Then, the next lottery becomes possible, etc.

This allows users to trade-in their winning items to the lottery service operator rather than selling them at second-hand goods dealers, online auctions, etc., thereby preventing a decline in the rarity of winning items. will be possible.

Note that the specific information displayed on the screen of the terminal 103 includes
Consideration information indicating the exchange consideration,
It is also possible to include deadline information or the like indicating a deadline set for the winning item. By including this information, the user can be provided with materials for deciding whether to wait for the winning item to arrive, whether to cancel the winning item, and how long the user can cancel the winning item.

Furthermore, if the cancellation request is not accepted by the set deadline (see FIG. 4), the output unit 115
Shipping information indicating that the identified item should be shipped, or
Manufacturing information indicating that manufacturing of the identified item should be started may be output.

That is, the server 102 outputs the shipping information and manufacturing information (210), thereby starting the shipping process for the winning item.

Note that the shipping information and manufacturing information can also be manually acquired from the lottery database by the operator of the lottery service. However, by using the output unit 115, it is possible to automatically issue instructions to the inventory manager to ship the winning item, and to issue instructions to the manufacturer to manufacture the winning item.

(Lottery processing)
FIG. 5 is a flowchart showing the control flow of the lottery process executed by the server in the lottery system. This will be explained below with reference to this figure.

When starting this process, the server 102 performs various initializations (step S301), and waits for a request from the terminal 103 to be received (step S302).

When the user accesses the server 102 from the terminal 103 and attempts to start the lottery service, the server 102 receives a start request from the terminal 103 (step S302; start). Then, the server 102 acquires account information of the user who uses the terminal 103 (step S303). The account information includes, for example, the number of points currently owned by the user, and payment information such as the credit card used to pay the lottery price.

Then, the server 102 generates a lottery form based on the account information (step S304), and transmits the generated lottery form to the terminal 103 (step S305). Thereafter, the server 102 returns control to step S302.

Terminal 103 displays the received lottery form on the screen. FIG. 6 is an explanatory diagram showing the state of the lottery form. This will be explained below with reference to this figure. Note that in the following explanation, objects placed within a form that can be selected by the user will be referred to as "links," but "links" can be used to refer to anchor elements in HTML (HyperText Markup Language) as well as other GUI elements. It can also be realized by a (Graphical User Interface) element, for example, a button object.

As shown in this figure, the lottery form 401 includes a point column 402 that displays the points that the user currently owns, a history link 403 that displays a list of prizes won in the past, and a Lottery information 404 indicating possible lots is displayed. The lottery information 404 includes a target item column 405 that indicates the items that are eligible for the lottery, and a participation link 406 that specifies the lottery price to be paid in order to participate in the lottery.

In this figure, the lottery form 401 is displayed in a scrollable manner, and the lottery information 404 at the top includes a target product column 405 indicating items A to F and a participation link 406 with a participation fee of 500 yen. ing. The lottery information 404 in the middle row includes a target product column 405 indicating items P to U, and a participation link 406 with a participation fee of 1000 yen. The lottery information 404 at the bottom is only displayed halfway, and the target product column 405 includes items X to W.

When the user selects the participation link 406 on the terminal 103, a lottery request is made, and the lottery request is transmitted from the terminal 103 to the server 102.

When the server 102 receives the lottery request (Step S302; Lottery), the server 102 executes charging processing for the lottery consideration for the user (Step S306). Note that the billing process may use a credit card or debit card included in the account information, or may allow the user to select a billing method via the terminal 103.

In Figure 6, "800" is displayed in the point column 402, so if you select the participation link 406 in the upper row, 500 points will be consumed, and the remaining points can be "300", and the participation link in the middle row will be consumed. When the link 406 is selected, all the points are consumed and the lottery consideration is paid, such as 200 yen being charged to the credit card or the like.

Then, the server 102 executes the lottery by specifying one of the items to be selected for the lottery according to the probability assigned to each item (step S307).

Then, the server 102 registers the user's account information and the winning item identified as a result of the lottery in the lottery database in association with each other (step S308).

Furthermore, the server 102 obtains the deadline set for the winning item (step S309). This deadline is, for example,
the last date and time on which the said lottery will be held;
Various modes can be adopted, such as after a predetermined period of time has elapsed since the lottery was executed. Further, it may be common to all items to be drawn by lottery, or may be different for each item.

Then, the server 102 generates a winning form including specific information regarding the winning item (step S310), and transmits it to the terminal 103 (step S311). Thereafter, the server 102 returns control to step S302.

Terminal 103 displays the received winning form on the screen. FIG. 7 is an explanatory diagram showing the state of the winning form. This will be explained below with reference to this figure.

As shown in this figure, the winning form 501, like the lottery form 401, includes a point field 402, a history link 403, and also displays specific information 502. The winning form 501 also includes a continuation link 507 for conducting a new lottery. When the user selects the continuation link 507, the terminal 103 transmits a start request to the server 102, thereby making it possible to request a new lottery.

The specific information 502 includes a winning item column 503 that shows the details of the winning item, a deadline column 504 that shows the deadline by which the winning item can be canceled, and a cancellation link 505 that specifies the exchange price that will be obtained if you cancel the winning item. is included.

In this figure, the fact that item B was won as a result of selecting the participation link 406 in the lottery information 404 at the top of the lottery form 401 in Figure 6 is displayed in the winning item column 503 of the specific information 502. It is displayed in the cancellation link 505 that the exchange consideration is 400 points.

Furthermore, since 500 yen (500 points) was used to participate in the lottery, the remaining amount displayed in the point column 402 has changed to 300.

Here, when the user selects the cancellation link 505 placed in any form on the terminal 103, this means that the cancellation request has been accepted, and the terminal 103 transmits the cancellation request to the server 102.

When the server 102 receives the cancellation request (step S302; cancel), the server 102 sends information to the user using the terminal 103 that sent the cancellation request that the winning item related to the cancellation request should be shipped. By deleting the winning item from the lottery database, shipping of the winning item is canceled (step S312), and the points related to the winning item are added to the point balance of the user, thereby giving an exchange value (step S313).

Thereafter, the server 102 returns control to step S303 and allows the user to draw a new lottery.

Now, when the user selects the history link 403 placed in any form on the terminal 103, a history request is sent from the terminal 103 to the server 102.

When the server 102 receives the history request (step S302; history), the server 102 accesses the lottery database to obtain information on the winning items (step S314), generates a history form (step S315), and sends it to the terminal 103. (Step S316). Thereafter, the server 102 returns control to step S302.

Terminal 103 displays the received history form on the screen. FIG. 8 is an explanatory diagram showing the state of the history form. This will be explained below with reference to this figure.

The history form 601 includes a point field 402 and a continue link 507 similar to the winning form 501, and also lists history information 602 related to each winning item won in the past. In this figure, history information 602 is displayed in a scrollable manner.

Each history information 602 includes a winning item column 503 showing details of the winning item. Furthermore, if the winning item can still be canceled (that is, the current time is before the set deadline), a deadline column 504 and a cancellation link 505 are displayed, as in the history information 602 at the top of the figure.

On the other hand, if the winning item cannot be canceled (that is, the current time is after the set deadline), the current status of the winning item is ``In production'', ``Shipped'', etc., as shown in the history information 602 in the middle of this figure. Instead of displaying the current status column 606 indicating the current status column 606, the deadline column 504 and the cancellation link 505 are not displayed. In other words, it is made impossible to perform a cancellation request operation to cancel a winning item.

Note that if the server 102 receives another request (step S302; other), it executes the corresponding process (step S317) and returns control to step S302.

By having the server 102 execute the above-mentioned lottery process, the user can receive a replacement price instead of canceling the winning item once won in the lottery.

In addition, since the lottery database is updated through the above processing, the server 102 can output manufacturing information and shipping information by accessing the lottery database and extracting information through, for example, batch processing that is executed periodically every day. It becomes possible to do so.

(exchange consideration)
In this embodiment, instead of canceling the shipping of the winning item, the user is given an exchange price. Below, various aspects of how to determine the exchange consideration will be explained.

The simplest mode is to make the exchange consideration equal to the lottery consideration. In this aspect, by paying the lottery price only once, the user can repeat canceling the winning item and holding a new lottery until the desired item is won.

Another simple embodiment is to make the exchange consideration smaller than the lottery consideration. This is in accordance with the general business practice that the trade-in price of a product is lower than the price at the time of purchase, and it is not possible to repeat the lottery indefinitely until the desired item is won for the price of one lottery. It disappears. For example, the exchange consideration can be determined by multiplying the lottery consideration by a constant α greater than 0 and less than 1.

In addition, the exchange price can be determined in consideration of the rarity of the winning item. For example, if you participate in a lottery by paying lottery consideration M, and you win an item with probability of winning p, the exchange consideration C will be
C = (M/p)×α
It can be determined by

Here, M/p represents the expected value of the lottery consideration paid by the user, assuming that the lottery is repeated until the winning item is won, and this will be referred to as the expected value. By multiplying the expected value by the above constant α, it is possible to determine the exchange consideration C that is smaller than the expected value.

In addition, when multiple winning items are shipped together at the same time, the consideration can be determined taking into account the shipping charges.

That is,
The type of winning item that is subject to a decision on whether or not to exchange it,
The number and type of other winning items that should be shipped at the same time as the winning item, and
The exchange consideration can be determined accordingly.

If there are no other winning items to be shipped at the same time, the exchange consideration C can be determined using the method described above. This exchange consideration C will be referred to as the first consideration.

Also, if there are other winning items that should be shipped at the same time, please first
The first shipping fee required when shipping the winning item that is subject to judgment along with other winning items,
The second shipping fee required when shipping only other winning items,
Calculate.

and,
1st consideration + (1st shipping fee - 2nd shipping fee)
shall be the exchange consideration for the winning item that is the subject of the judgment.

With this method, when multiple winning items are shipped together in one package, it is possible to provide materials for the user to decide whether or not to cancel the winning item, taking into consideration the shipping effort. Become.
