In the present embodiment, the item lottery process is executed by using the lottery ticket. That is, a lottery ticket is given to the user who uses the client 104 in advance, and the user can perform the item lottery process by using the lottery ticket. However, the item lottery process may be performed according to the payment of virtual currency or cash without using the lottery ticket.

It is assumed that the lottery ticket has been distributed to the users in advance. The method of distributing the lottery ticket is not particularly limited, and any method may be used as long as it is electronically distributed to the user who uses the client 104.

For example, a lottery ticket can be given according to the situation of the electronic game by the user signing in to the account of the electronic game from the client 104 to the server 102 and playing the electronic game.

Further, for example, the lottery ticket can be given when the user signs in to an account such as SNS from the client 104 to the server 102 and a predetermined condition is satisfied.

Further, for example, a user who uses the client 104 visits a store that sells products or provides a service, and the lottery ticket is given to the user by inputting the information attached to the lottery ticket distributed at the store to the client 104. It may be given as such.

The lottery ticket may be charged or free. For example, a lottery ticket may be given by paying virtual currency or cash. At this time, it is preferable that the price of the lottery ticket is set cheaper than when the lottery is executed by payment of virtual currency or cash. This can motivate the lottery to be drawn using the lottery ticket.

Further, a lottery ticket may be given when a specific item is used in an electronic game or a specific process is executed in an SNS or the like.

FIG. 4 shows an example of a lottery ticket database showing the grant status of lottery tickets. The ticket ID, the owning user ID, the issue date and time, the right generation date and time, and the usage information are stored in the lottery ticket database. The ticket ID is an identifier for identifying the information lottery ticket. The ticket ID can be, for example, the issue number of the lottery ticket. The owning user ID is an identifier for identifying the user who owns the lottery ticket. The owning user ID can be a user name assigned to each user. The issue date is information indicating the date and time when the lottery ticket was issued. The right generation date and time is information indicating the date and time when the lottery by the lottery ticket can be executed. That is, in the present embodiment, the lottery ticket becomes valid after the user acquires the lottery ticket and a predetermined period of time elapses, and the item can be drawn. For example, the lottery ticket may be activated after a predetermined time has elapsed from the date and time when the user obtained the lottery ticket. Further, for example, the lottery ticket may be activated at a predetermined date and time after the date and time when the user obtained the lottery ticket. The usage information is information indicating whether the lottery ticket is unused or used. The information registered in the lottery ticket database is not limited to these, and other information such as the issuer of the lottery ticket may be stored.

Hereinafter, the item lottery process in the present embodiment will be described with reference to the flowchart of FIG. The item lottery process can be applied, for example, when providing an item to a user (player) in an electronic game or when providing an item to a customer when providing a service in a store. However, the scope of application of the item lottery process is not limited to these.

In step S10, the initial setting is performed. By the process in the step, the lottery system 100 functions as an initial setting means.

The item database is registered on the server 102. The server 102 stores the item to be drawn by lottery and the winning probability of each item in the storage unit 12 as an association item database.

FIG. 6 shows an example of an item database. In the item database, the item ID, the item name, and the winning probability of the item are stored in association with each other. The item ID is an identifier uniquely assigned to each item and for identifying the item. The item name is the name of each item. The item winning probability is information indicating the probability that the item will be won in the lottery process described later. The winning probability of the item is the probability in the normal lottery process, and the winning probability may be changed depending on the process to perform the lottery.

In addition, other items such as item characteristics and item effects may be associated and stored in the item database. For example, if it is an item used in an electronic game, the characteristics and effects when it is used in the electronic game may be stored together. Further, for example, in the case of an item used for a service in a store, the price discount rate of the product / service when the item is used may be stored together.

In step S12, a process of receiving an instruction to start the lottery process is performed. By the process in this step, the lottery system 100 functions as a lottery instruction receiving means.

The user connects the client 104 to the server 102 via the information communication network 106. For example, when an item lottery process is performed in an electronic game, the user activates an electronic game providing application using the client 104 and connects to the server 102. Further, for example, when receiving a service provided at a store, the user activates a service providing application provided from the store using the client 104 and connects to the server 102. At this time, a sign-in process such as login may be requested if necessary.

In this way, with the server 102 and the client 104 connected, the client 104 sends an instruction to the server 102 to draw an item. Specifically, the user uses the input unit 24 of the client 104 to input to specify the lottery ticket to be used for the item lottery.

For example, in an electronic game or the like, a lottery instruction is given when an operation indicating that the user desires to acquire an item is performed using the input unit 24 of the client 104. Further, for example, in an electronic game or the like, a lottery instruction is given when the stage shifts to a stage for drawing an item (so-called stage such as an electronic gacha). Further, for example, when receiving a service at a store, a lottery instruction is given when an operation indicating that the user desires to obtain a discount coupon for a predetermined product is performed using the input unit 24 of the client 104. Further, for example, when a predetermined barcode, QR code (registered trademark), or the like is scanned using the input unit 24 of the client 104, a lottery instruction is given. However, the conditions under which the lottery instruction is given are not limited to these.

Here, the waiting time until the lottery ticket becomes valid may be presented to the user. For example, as shown in FIG. 7, a lottery image 200 (for example, an electronic gacha image) for drawing an item is displayed on the output unit 26 of the client 104, and the lottery is performed in the waiting time display area 202 in the lottery image 200. The time remaining until the ticket becomes valid may be displayed. Specifically, the lottery ticket database stored in the storage unit 12 of the server 102 is referred to, and the ticket ID and the right generation date and time of the lottery ticket associated with the owned user ID of the user who uses the client 104 are read out. , The server 102 transmits the information to the client 104. Then, the client 104 displays the difference between the received right generation date and time and the current date and time as the remaining time in the waiting time display area 202.

The lottery image 200 may be displayed only on the client 104 of the user who owns the lottery ticket. That is, the lottery image 200 is released only to the user who owns the lottery ticket before the date and time when the right of the lottery ticket is generated. This can motivate the user who wants to get the lottery image 200 earlier to obtain the lottery ticket.

Further, for example, as shown in FIG. 8, a ticket display image 210 showing the possession status of the lottery ticket is displayed on the output unit 26 of the client 104, and the lottery ticket list display unit 212 displayed on the ticket display image 210. The remaining time until the ticket becomes valid may be displayed for each lottery ticket. Specifically, the lottery ticket database stored in the storage unit 12 of the server 102 is referred to, and the ticket ID and the right generation date and time of the lottery ticket associated with the owned user ID of the user who uses the client 104 are read out. , The server 102 transmits the information to the client 104. Then, the client 104 displays the ticket ID indicating the lottery ticket owned by the user and the difference between the right generation date and time and the current date and time in association with each other as the remaining time in the ticket display image 210.

By confirming these displays, the user can specify the lottery ticket by using the input unit 24 of the client 104 and give the lottery instruction.

Further, the user may be notified by push notification when the lottery ticket becomes available, or the user may be notified by push notification of the time until the lottery ticket becomes valid or the date and time when the lottery ticket becomes valid. Specifically, the lottery ticket database stored in the storage unit 12 of the server 102 is referred to, and the ticket ID and the right generation date and time of the lottery ticket associated with the owned user ID of the user who uses the client 104 are read out. , Information indicating that the lottery ticket has become available may be transmitted from the server 102 to the client 104 when the current date and time reaches the right generation date and time. The client 104 may display on the output unit 26 indicating that the lottery ticket has become available, such as "The lottery ticket has enabled the lottery of items!". Further, on the client 104, for example, the output unit 26 may display information indicating the time until the lottery ticket becomes valid and the date and time when the lottery ticket becomes valid.

By confirming these push notifications, the user can specify the lottery ticket by using the input unit 24 of the client 104 and give the lottery instruction.

When the client 104 receives the lottery instruction from the user, the client 104 transmits the information indicating that the lottery instruction has been received and the information (ticket ID, etc.) for identifying the lottery ticket to be instructed to the server 102. When the server 102 receives the item lottery instruction from the client 104, the server 102 shifts the process to step S14.

In the period until the right generation date and time when the lottery ticket becomes valid is reached, the item may be given to the user who owns the lottery ticket every time a specific time or period elapses. For example, an item may be given to the user who owns the lottery ticket every day until the right generation date and time when the lottery ticket becomes valid is reached. In addition, in the period until the right generation date and time when the lottery ticket becomes valid is reached, an item is given to the user who owns the lottery ticket by executing a predetermined process every time a specific time or period elapses. You may. For example, until the right generation date and time when the lottery ticket becomes valid is reached, the item is displayed to the user who owns the lottery ticket by transitioning to a specific screen (for example, the home screen of the electronic game) every day. It may be given.

When the item is given, the server 102 transmits the information indicating the item to the client 104 in step S16 via the information communication network 106. The client 104 performs a process of associating the item with the user. For example, an item ID indicating an item assigned to the user's own item database stored in the storage unit 22 of the client 104 is newly registered. As a result, the user using the client 104 can acquire the item.

In step S14, the validity of the lottery ticket is determined. By the process in this step, the lottery system 100 functions as a ticket determination means. When the processing unit 10 of the server 102 receives the lottery instruction in step S12, it determines whether or not the lottery ticket, which is the target of the instruction, is valid. The processing unit 10 of the server 102 refers to the lottery ticket database stored in the storage unit 12 and reads out the usage information associated with the information (ticket ID, etc.) that identifies the lottery ticket to be instructed. Determine if the lottery ticket is unused or used.

If it is unused, the right generation date and time associated with the information (ticket ID, etc.) that identifies the lottery ticket to be instructed is read, and it is determined whether or not the current date and time has reached the right generation date and time. .. Then, if the current date and time has reached the right generation date and time, it is determined that the lottery ticket is valid, otherwise it is invalid.

If the lottery ticket is valid, the process shifts to step S16, and if it is invalid, the process returns to step S10.

In step S16, the item lottery process is performed. By the processing in this step, the lottery system 100 functions as a lottery processing means. Hereinafter, the lottery process will be described with reference to FIG.

In the lottery process, the server 102 draws items based on the winning probability of each item stored in the item database. Specifically, the following processing is performed.
(1) Refer to the item database and read the winning probability for each item. For example, in the case of the item database shown in FIG. 6, the winning probabilities for each item such as item A: 1%, item B: 2%, item C: 0.1%, and so on are read out. (2) Set the weight for each item based on the winning probability. For example, the winning probability (%) of each item is multiplied by 100 to set the weight for each item. In the case of the item database shown in FIG. 6, item A: 1 (%) × 100 = 100, item B: 2 (%) × 100 = 200, item C: 0.1 (%) × 100 = 10, ...・ And the weight for each item is set. (3) Set each item in the array at a frequency according to the weight of each item, and then shuffle the order of the array. For example, as shown in FIG. 9, item A is set in arrays 0 to 99, item B is set in arrays 100 to 299, and item C is set in arrays 300 to 309. Then shuffle the array. (4) It is assumed that a random number with the number of arrays as the upper limit is generated, and the item associated with the array number corresponding to the random number is won. For example, when a random number value of 302 is obtained by generating a random number, it is assumed that the item B associated with the array number 302 in the shuffled array is won.

However, the specific lottery method for items is not limited to this, and a lottery method may be adopted in which each item is won according to the winning probability based on the item database.

For example, a lottery method called a so-called box gacha may be applied. In this case, the items that have already been won may be excluded from the next lottery process, and the lottery process may be performed by varying the winning probability for each item. Specifically, the items won in the lottery may be excluded from the array set in (3) above, and the array may be set again.

Here, when the lottery is performed using the lottery ticket, the winning probability of the item may be changed with respect to the case where the lottery is performed by another method such as cash payment. For example, the winning probability for item A when a lottery is performed by paying cash may be set to 1%, and the winning probability for item A when a lottery is performed using a lottery ticket may be set to 2%. In particular, for a lottery using a lottery ticket by setting the winning probability for a rare item, which is considered to have a low winning probability, higher when the lottery is performed using a lottery ticket than when the lottery is performed by another method. Can be motivated.

Further, the winning probability of the item when the lottery is performed using the lottery ticket may be changed according to the period of waiting until the lottery ticket is used. For example, it is preferable that the longer the waiting period before using the lottery ticket, the higher the probability of winning the item. Specifically, for example, the waiting period may be divided by a specific number, and the calculated division value may be used to correct the normal winning probability of the item. That is, when the normal winning probability for item A is 1%, the winning probability is 4% when the waiting period until the lottery ticket is used is 3 days, and the winning probability is 6% when the waiting period is 5 days. When the period is 7 days, the winning probability may be set to 8%.

In addition, when the lottery is performed using the lottery ticket, the items subject to the lottery may be changed with respect to the case where the lottery is performed by another method such as cash payment. For example, when a lottery is conducted using a lottery ticket, items that are not subject to the lottery may be added to the lottery when the lottery is conducted by another method such as cash payment. As a specific example, when the lottery is performed by other methods such as cash payment, the lottery is performed for items A, B, and C, and when the lottery is performed using the lottery ticket, the item A is used. , B, C and item D are added to the lottery. At this time, the winning probability for each item may be set for each case.

In step S18, a process of providing the user with the item won by the lottery process is performed. By the process in this step, the lottery system 100 functions as an item providing means.

The server 102 transmits information indicating the winning item in step S16 to the client 104 via the information communication network 106. The client 104 performs a process of associating the winning item with the user. For example, an item ID indicating a winning item is newly registered in the user's own item database stored in the storage unit 22 of the client 104. As a result, the user using the client 104 can acquire the item.

Here, when the lottery is performed using the lottery ticket, additional additional items may be given to the case where the lottery is performed by another method such as cash payment. For example, when a lottery is performed using a lottery ticket, in addition to the items won in step S16, items that are not given when the lottery ticket is not used may be given as additional items as a bonus. This means that additional items may be changed according to the period of waiting before using the lottery ticket. For example, the longer the waiting period before using the lottery ticket, the more rare items may be given.

Although the waiting time is not changed depending on the number of lottery tickets issued, the waiting time may be changed depending on the number of lottery tickets issued.

For example, the waiting time may be lengthened as the number of lottery tickets issued increases. As a specific example, a process of adding a waiting time is performed every time the number of lottery tickets issued reaches a specific number. For example, the waiting time for lottery tickets issued from 1 to 300 is 24 hours, the waiting time for lottery tickets issued from 301 to 500 is 26 hours, and the waiting time for lottery tickets issued is 501 to 700. The time may be 28 hours or the like. Further, the waiting time may be lengthened each time the number of lottery tickets issued increases. For example, each time a lottery ticket is issued, the waiting time may be increased by one minute.

In this case, the server 102 stores the number of issued lottery tickets in the storage unit 12 for each type of lottery ticket, and the date and time when the right is generated to be registered in the lottery ticket database for the newly issued lottery ticket according to the number of issued lottery tickets. Should be adjusted.

In this way, by changing the waiting time according to the number of lottery tickets issued, the user can be motivated to obtain the lottery ticket quickly. For example, in a so-called box gacha, in which the number of items to be drawn is reduced with each lottery, it is possible to motivate a user who wants to draw early to obtain a lottery ticket earlier.
