[Overview of the game]
The game machine 30 provides various games such as training games, music games, action games, role-playing games, puzzle games, simulation games, adventure games, shooting games, sports games, and racing games. An example in which a mobile phone serving as the mobile game machine 30C provides a character breeding game will be described below.

A user trains a character in the training game. The characters include persons with jobs such as dancers, monsters, athletes, warriors, or objects such as cars or animals. Also, the character to be trained may be one or more. As an example, a training game (hereinafter simply referred to as a game) for training a team including a plurality of dancers as a dance unit will be described below.

The user develops each character forming a dance unit through various events in the game. For example, training events include mini-games, and the user trains each character by playing the mini-games. Mini-games include various types of games, and one example includes a music game, which is a type of timing game. Then, in the timing game, the execution timing of an appropriate play action is evaluated. As a specific example, execution times at which appropriate play actions should be performed are provided with the music. Then, the timing that coincides with the rhythm of the music is used as the execution timing. In other words, the user is guided to the time when an appropriate play action should be performed in accordance with the rhythm of the music, and the time when the user actually performed the play action is evaluated.

A plurality of songs are prepared for play in the music game, and a song selected by the user from the plurality of songs is used for actual play. For example, a music game is provided through a game screen displayed on the game machine 30. FIG. Specifically, the game screen displays an instruction indicator corresponding to each execution period and a reference indicator that functions as a reference for the current time. Then, the game machine 30 uses the instruction mark and the reference mark to cause relative displacement between the instruction mark and the reference mark so that the positions of the instruction mark and the reference mark match at each execution time. Thereby, the game machine 30 guides the user when to execute the game operation.

Additionally, in the game, the user obtains in-game currency in exchange for value represented either by money or a substitute for money. The user can then use the acquired in-game currency in the game. It should be noted that money means value expressed quantitatively by legal currency, and does not need to be cash. Alternatives to money are various economic values such as electronic currency, points, and coupons issued by specific business operators. Furthermore, the user can obtain in-game currency free of charge when a predetermined condition is met. For example, the predetermined conditions are reaching a predetermined level in game results, logging in to the game, and the like.

The server 20 cooperates with a settlement server (not shown) via the network NT as necessary in order to make a settlement when the user acquires the in-game currency. The settlement server may be managed by a specific business operator. For example, a specific business is a card company, a financial institution, or an issuer of electronic currency that performs payment processing using a credit card or debit card. Alternatively, server 20 may function as a settlement server.

By appropriately using the in-game currency, the user can proceed with the game while receiving various services related to the game. For example, a user can spend in-game currency to exercise a lottery right to win a winning game element. Also, the user can exchange in-game currency for items prepared in the game. The in-game currency used by the user is consumed in exchange for granting the item for which it is used. Consumption here means that the user cannot use the in-game currency again. For example, when an item is given to a user in exchange for a predetermined amount of in-game currency, the predetermined amount is subtracted from the amount of in-game currency possessed by the user.

[Game screen]
Next, game screens in the game will be described with reference to FIGS. 2 to 5. FIG. FIG. 2 schematically shows an example of the home screen 40. As shown in FIG. Also, FIG. 3 schematically shows an example of a lottery screen 50 for executing consecutive lotteries. Also, FIG. 4 schematically shows an example of a selection screen 60 for selecting a character for a selection lottery in a continuous lottery. Furthermore, FIG. 5 schematically shows an example of a lottery result screen 70 that displays the lottery results.

As shown in FIG. 2, home screen 40 serves primarily as a starting point to other game screens. Therefore, the home screen 40 displays icons that function as operation positions for transitioning to each screen. The user can display the game screen corresponding to the icon by performing a touch operation on each icon. For example, the home screen 40 displays a story icon 40A, a dancer icon 40B, a team icon 40C, a card icon 40D, a lottery icon 40E, an errand icon 40F, a dance battle icon 40G, a mission icon 40H, and a purchase icon 40I. . Further, on the home screen 40, an information area 48 for displaying information for management and a character image CA are displayed. For convenience of explanation, in FIG. 2, the information area 48 is indicated by a dashed frame that is not displayed on the actual game screen.

Various information related to the game is presented in the information area 48 . For example, the information area 48 displays the user name "Gogo" character string, coach rank, physical strength, amount of in-game currency, and the like. The coach rank is a value indicating the user's degree of growth in the game, and for example, the value increases as the user plays more games. In the example of FIG. 2, the coach rank is "1". In addition, the physical strength value indicates the current value and the upper limit value of the physical strength value of each character. In the example of FIG. 2, the current value is "30" and the upper limit value is "30". A recovery icon 48A is displayed next to the physical strength value. The user can use recovery items by touching the recovery icon 48A. Alternatively, by touching the recovery icon 48A, a screen for selecting a recovery item or a screen for confirming whether or not the recovery item can be used may be popped up. A physical strength value is consumed by playing an event or a music game.

The amount of in-game currency that is possessed decreases when it is consumed to purchase items or use predetermined functions such as various lotteries. On the other hand, the possession amount increases when in-game currency is purchased or given free in-game currency. In the example of FIG. 2, the amount of in-game currency possessed is "0". A currency purchase icon 48B is displayed next to the amount of in-game currency possessed. The user can purchase in-game currency and increase the possession amount by touching the currency purchase icon 48B. For example, when the user touches the currency purchase icon 48B, a screen for selecting the amount of in-game currency to be purchased or a screen for confirming whether or not the purchase is possible pops up. Alternatively, when the user touches the currency purchase icon 48B, the home screen 40 may transition to a purchase screen (not shown). In this case, the user can purchase the in-game currency through the purchase screen displayed by touching the purchase icon 40I.

When the user touches the story icon 40A, the home screen 40 transitions to a story screen (not shown). On the story screen, the user can select and watch a story or animation set for each character. For example, the user can select a story set for each character or conversation animation with multiple characters. The story set for each character can be selected according to the progress of the game, such as obtaining a reward in the game or reaching a predetermined level of the character. Also, when the user touches the dancer icon 40B, the home screen 40 transitions to a character screen (not shown). The character screen displays character images CA and detailed information about each character. Also, on the character screen, a costume selection column can be displayed. The user can change the costume worn by the character by selecting the costume owned by the user. Note that the user can acquire costumes by exchanging them for in-game currency, executing events, completing missions, executing lotteries, and the like.

Furthermore, when the user touches the team icon 40C, the home screen 40 transitions to a team formation screen (not shown). The team formation screen allows the user to select a plurality of characters that form a dance unit. Also, when the user touches the card icon 40D, the home screen 40 transitions to a card breeding screen (not shown). On the card training screen, the user can use items, such as items for obtaining experience points. This allows the user to upgrade the level of the digital card he or she owns.

When the user touches the lottery icon 40E, the home screen 40 transitions to the lottery screen 50 shown in FIG. On the lottery screen 50, the user can exercise the lottery right to perform consecutive lotteries. For example, a lottery information icon 51 that can be selected by the user is displayed on the lottery screen 50 . Then, the user can display the lottery information column 53 by performing a touch operation on the lottery information icon 51 . Further, the user can exercise the lottery right by consuming a predetermined amount of in-game currency by touching the lottery determination icon 54 . The user can obtain a digital card or an item such as a costume according to the lottery result. In the example of FIG. 3, the lottery information icon 51 is selected in order to execute a continuous lottery in which three digital card lotteries are performed. Alternatively, the number of consecutive draws may be two or four or more. A plurality of lottery information icons 51 may be arranged in parallel, and when the user touches another lottery information icon 51, a single lottery or another type of continuous lottery may be performed.

The images of the digital cards of the characters are configured to have different types due to different appearances such as poses and costumes. Also, the costumes worn by the characters on the digital card may be selected as costumes for each character when playing the music game. This digital card may not be usable in the game. In this case, the user satisfies the collection desire by collecting digital cards. Digital cards, on the other hand, may be usable in games. For example, by selecting a digital card, the character corresponding to the digital card may be reproduced in the game. The characters reproduced in the game may have different skills based on the digital cards. Furthermore, the card image of the digital card may be configured so that it can be printed out on a physical card. As an example, the data representing the card image is read from the game machine 30 or the server 20 to an external output device. Then, the digital card selected by the user is output from the output device as a physical card according to the operation of the output device by the user.

Furthermore, the lottery screen 50 displays a home icon 52 . The lottery screen 50 also displays a possession amount area 58 that displays the possession amount of in-game currency acquired for a fee and the possession amount of in-game currency acquired free of charge. For convenience of explanation, in FIG. 3, the possession amount area 58 is indicated by a dashed frame that is not displayed on the actual game screen.

When the user touches the lottery history button 53A in the lottery information column 53, a pop-up screen showing the lottery history is displayed. Also, when the user touches the winning probability button 53B in the lottery information column 53, a pop-up screen showing the winning probability of each digital card is displayed. Furthermore, when the user touches the home icon 52 , the lottery screen 50 transitions to the home screen 40 . Then, when the user touches the lottery decision icon 54, continuous lottery is started, and the selection screen 60 shown in FIG. 4 is displayed.

On the selection screen 60 shown in FIG. 4, the user can perform a selection operation to select at least one selection population. That is, a plurality of candidate icons 61A, 61B, and 61C are displayed on the selection screen 60 as candidates for the selection population. Then, the user selects a desired one from the plurality of displayed candidate icons 61A, 61B, 61C. As a result, a lottery is performed from the selection population selected by the user. In the example of FIG. 4, the names of three characters are displayed, and a selection population corresponding to each character is set in advance. That is, in the present embodiment, the selection population is set such that when one of the three characters is selected, one of the plurality of digital cards related to the selected character is won. The user selects a desired character and touches the candidate icons 61A, 61B, 61C. This allows the user to perform a selective lottery, in which a lottery is drawn from among a selection population of his own choosing, as part of a continuous lottery. Each selection population contains a plurality of corresponding character digital cards. Furthermore, the plurality of digital cards differ from each other in terms of costumes, rarity, parameters, or the like. In addition, you may comprise a continuous lottery so that a user may select two or more selection populations. Also, the user can cancel the selection of the selected population by selecting the cancel button 62 .

When the user touches the candidate icons 61A, 61B, 61C, a confirmation screen pops up. Then, when the user confirms, consecutive lotteries are executed, and a lottery result screen 70 shown in FIG. 5 is displayed. Before the lottery result screen 70 is displayed, a screen for lottery effect is separately displayed. The lottery result screen 70 shows an example in which three digital cards corresponding to each character have been won as game elements related to the breeding game. The card image 71 of the digital card indicates the digital card obtained by the lottery this time, and includes character images corresponding to each character.

Also, the card image 71 of the digital card obtained for the first time is attached with information indicating that it has been obtained for the first time (for example, a character string of "NEW"). Also, when the same digital card as the already acquired digital card is obtained in duplicate as a result of the lottery game, the acquired digital card is automatically combined with the already acquired digital card. The card image 71 corresponding to the combined digital card is attached with information indicating the number of times of combining (for example, a character string such as "limit breakthrough 2"). Along with the synthesis, the parameter of the already obtained digital card or the upper limit value of the parameter is increased by a predetermined amount. Then, the association between the duplicately obtained digital card and the user is released. It should be noted that the increase of the parameters and the like may be omitted at the time of synthesis.

An additional lottery icon 72 is also displayed on the lottery result screen 70 . The additional lottery icon 72 indicates the position of the touch operation for requesting an additional lottery for the digital card. That is, when the additional lottery icon 72 is touched, the lottery for the digital card is executed again. The additional lottery is executed along with the consumption of the in-game currency, and in the example of FIG. 5, the additional lottery icon 72 indicates that 135 in-game currencies are consumed. The additional lottery executed by touching the additional lottery icon 72 is a normal lottery, not a continuous lottery. Alternatively, a continuous lottery may be executed again by a touch operation on the additional lottery icon 72 . Furthermore, a lottery TOP icon 73 is displayed on the lottery result screen 70 . When the user touches the lottery TOP icon 73 , the lottery result screen 70 transitions to the lottery screen 50 .

Three card images 71 are displayed as the lottery result on the lottery result screen 70 shown in FIG. In other words, it indicates that the user won three digital cards in this lottery. Each digital card is collected by the user and owned primarily for viewing purposes. Also, the costume worn by the character of each card image 71 can be selected as the costume of each character when playing the music game. In other words, the costume of the card image 71 is used as a dance costume or the like in accordance with possession of each digital card. Therefore, in addition to the purpose of collection, the user holds a lottery to obtain the costume.

Various characteristics such as dance skills may be set for each character. Further, the properties may include properties related to growth. For example, a character with a high rarity (so-called rarity) may be given the characteristic of growing faster than other characters even if the character has the same experience. Furthermore, dance skills may include skills that are granted only when various conditions such as play situations are satisfied. Each digital card may also be used for play in a game. For example, each digital card may be configured to make the character corresponding to the digital card appear in the game through selection on a team formation screen or the like. Specifically, characters with different skills or rarities appear in the game according to appropriate conditions such as play situations or lottery. Characters with different skills and the like are reproduced in the game. Even if the characters are the same, if they have different skills, they may appear in the game at the same time. Further, the card image 71 may be actually printed on a physical card and issued to the user by an appropriate method.

Returning to FIG. 2, when the user touches the errand icon 40F, the home screen 40 transitions to an errand screen (not shown). On the errand screen, the user can select an acquisition event for acquiring an item. Acquisition events are provided along with consumption of a predetermined value set in the game. For example, the predetermined value is the physical strength value, which is a parameter set for the character. The physical strength value recovers to the upper limit with the passage of time, and also recovers when the user uses recovery items. Furthermore, when using a recovery item, it may be possible to recover beyond the upper limit. Note that the user can obtain recovery items by exchanging for a predetermined amount of in-game currency.

Furthermore, when the user touches the dance battle icon 40G, the home screen 40 transitions to a music game screen (not shown). On the music game screen, the user can select a dance unit to develop through playing the music game. Also, the user can select an autoplay mode by consuming an autoticket, which is a type of item, on the music game screen. In the auto play mode, evaluation of game operations to be performed by each user is automatically evaluated as a predetermined evaluation result. That is, when the auto-play mode is selected, the user is given a predetermined evaluation result, for example, a predetermined score, even if the user does not operate the game. A user can obtain an auto-ticket by exchanging it for a predetermined amount of in-game currency.

When the user touches the mission icon 40H, the home screen 40 transitions to a mission screen (not shown). The mission screen displays mission-related information such as a list of missions prepared during the game, achievement conditions, rewards associated with achievement, and achievement history. A mission is a type of event in which a predetermined reward is given to a user by satisfying achievement conditions. Also, when the user touches the purchase icon 40I, the home screen 40 transitions to a purchase screen (not shown). The user can purchase in-game currency on the purchase screen. Furthermore, the user can acquire items by consuming in-game currency on the purchase screen.

[Summary of consecutive lottery]
In the continuous lottery executed from the selection screen 60, lottery processing for lottery of at least one game element is continuously executed multiple times. That is, by one touch operation by the user on the selection screen 60, the lottery is executed a plurality of times, and a digital card, which is a plurality of game elements, is won. In addition to the normal lottery, the continuous lottery includes a selection lottery in which a selection population to be drawn by user operation is selected. In the normal lottery, at least one game element is drawn from a normal population containing a plurality of game elements. In the selection lottery, at least one game element is drawn from the selection population selected by the user.

On the other hand, when only the normal lottery is executed multiple times in the continuous lottery, a situation may arise in which the user's wishes cannot be met. For example, there is a so-called continuous gacha function in which a predetermined number of lotteries such as 10 or 11 times are performed by one operation by consuming a predetermined amount of currency or in-game currency. In this continuous gacha, winning game elements, that is, lottery populations, generally follow one theme. In other words, the user plays a series of gachas in order to obtain, for example, game elements whose parameters are set to exhibit advantageous effects in game events. However, not all users want themed game elements, and some users want a collection of various game elements. If only the normal lottery based on a specific theme is executed multiple times, the possibility that the user's wishes will be fulfilled will be low. In this way, there are situations in which it is not possible to meet the diverse wishes of users who have a variety of purposes for continuous lottery.

On the other hand, since the continuous lottery of the present embodiment includes the selection lottery described above, it is possible to meet the various wishes of the user. For example, one character appearing in a game is provided with a plurality of digital cards as game elements. That is, for each character, there are a plurality of digital cards with different rarities, versions, costume types, attributes, parameters, and the like. As a result, the number of types of digital cards increases according to the number of characters appearing in the game, and the user's desire to collect them can be stimulated. One of the means of obtaining digital cards is continuous lottery. Note that the digital cards may differ only in the character image. Alternatively, the digital cards may have the same character image but different parameters.

In the continuous lottery of this embodiment, for example, three lotteries are executed in one lottery operation, and three digital cards are won. A normal lottery is included in the three lotteries, and one digital card is selected by lottery from a normal population composed of a plurality of preset digital cards. Furthermore, the three lotteries include a selection lottery, and there are a plurality of selection populations, each of which is composed of a plurality of preset digital cards. selects one selection population. Then, one digital card is selected by lottery from the selection population selected by the user. Alternatively, the digital cards included in the normal population or the selected population may be automatically set each time a lottery is drawn. However, if the digital cards are set in advance, the lottery probability of each digital card, that is, the winning probability can be determined in advance. The winning probability of each digital card is displayed on the screen by touching the winning probability button 53B in the lottery information column 53 and presented to the user. This allows the user to select a selection population with reference to the winning probability.

Selection of the selection population is performed, for example, on the selection screen 60 (FIG. 4). That is, the selection screen 60 displays the character string "Please select the third character to be drawn" to prompt the user to make a selection. In the example of FIG. 4, three selection populations are set so as to include a plurality of digital cards for each of the three characters as the plurality of selection populations. In addition, of the three lotteries, the third lottery is a selection lottery. The selection of the selection population is made before the start of the continuous draw. Alternatively, the selection of the selection population may be made in the middle of a continuous draw.

The selection lottery may be performed last, and the candidate icons 61A, 61B, 61C may be displayed so as to select the selection population before the selection lottery starts. Thereby, the user can select the selection population by referring to the lottery results of the normal lottery before the selection lottery. That is, if the selection population is selected before the continuous lottery starts, the selection population cannot be changed even if the desired digital card is won in the normal lottery. Therefore, by executing the selection lottery after the normal lottery and selecting the selection population before executing the selection lottery, the user can refer to the lottery results in the normal lottery and select the selection population.

The digital cards included in the selection population may be standardized to a predetermined rarity. Also, the number of selection populations is not limited to three. That is, two or four or more selection populations may be set. Furthermore, multiple selection populations may be set according to specific events or the like. For example, when an event focusing on a particular dance unit is being held, a selection population may be set for each character that is a member of that dance unit. In addition, the normal population that is the target of the normal lottery can be set so as to include a plurality of digital cards with a uniform rarity, character, or the like. Alternatively, the selection population may consist of a plurality of user-selected digital cards. Furthermore, the user may sort and form the selection population so that the selection population is composed of digital cards with uniform conditions such as attributes (for example, gender or age). Further, the normal population may be a normal population or a selection population that has been included in a streak at past events.

Also, the selection population may be set so as not to include the digital cards normally included in the population. Furthermore, the selected population and the normal population may be set so as not to include the digital cards that were limited to lottery targets in events held in the past. For example, in a continuous lottery for another event, if there is a digital card that has been targeted for lottery for a limited time, the selected population and normal population are set so as not to include the digital card. However, even if the digital card is subject to a lottery for a limited time, it may be included in the selection population and the normal population if it meets certain conditions, such as using paid in-game currency. can be done.

[Configuration of game system]
Next, the configuration of the game system 100 will be described with reference to FIG. A game system 100 includes a server 20 and a game machine 30 . The server 20 also includes a server control unit 21 and a server storage unit 22, which is an example of storage means that stores the population information PI. The server control unit 21 has a selection unit 23 as an example of selection means, a lottery unit 24 as an example of lottery means, and an authentication unit 25 as an example of authentication means. The server storage unit 22 stores a server program PG1, population information PI, play data PD, and game data GD1. The game machine 30 also has a terminal control section 31 , a terminal storage section 32 , a monitor 37 which is an example of a display device, a speaker 35 and an input section 36 . The terminal control unit 31 has a display control unit 34 as an example of display control means, and a game control unit 33 as an example of game control means. The terminal storage unit 32 stores a terminal program PG2 and game data GD2.

The server control unit 21 and the terminal control unit 31 are configured as computers in which a processor that executes various arithmetic processing and operation control according to a predetermined program and other peripheral devices are combined. As an example, the processor is a CPU (Central Processing Unit) or an MPU (Micro-Processing Unit). The server control unit 21 controls the entire server 20 based on the programs stored in the server storage unit 22, and also comprehensively controls various processes. In addition, the terminal control unit 31 controls the entire game machine 30 based on the programs stored in the terminal storage unit 32, and comprehensively controls various processes.

The selection unit 23, the lottery unit 24, and the authentication unit 25 of the server control unit 21 function as functional units when the server 20 executes the server program PG1. The display control unit 34 of the terminal control unit 31 and the game control unit 33 function as functional units when the game machine 30 executes the terminal program PG2. Each functional unit is a logical device realized by cooperation of computer hardware and software.

The server storage unit 22 and the terminal storage unit 32 are computer-readable non-temporary storage media. The storage medium includes RAM (Random Access Memory), which is a system work memory for the processor to operate, and ROM (Read Only Memory), HDD (Hard Disc Drive) and SSD (Solid State Drive) for storing programs and system software. ) and other storage devices. In the following, an example will be described in which the CPU executes processing operations such as various calculations, controls, and determinations according to control programs stored in the ROM or HDD.

[Server configuration]
The server storage unit 22 stores population information PI including a plurality of selection populations each including a plurality of game elements. Game elements include all the elements that are targets of the lottery, and examples include objects appearing in the game such as items and characters, parameters, attributes, and the like. A plurality of game elements included in each selection population are set in advance. As an example, the population information PI includes, for example, a population ID as population identification information for identifying a selected population, and, for example, an element ID as element identification information for a game element associated with the population ID. there is The selection unit 23 can identify the game elements forming the selected population by referring to the population information PI. For example, the element ID is a card ID uniquely set for each digital card.

Furthermore, population information PI includes a normal population including a plurality of game elements, and the plurality of game elements are set in advance. As an example, the population information PI includes population identification information for identifying a normal population and element identification information for game elements associated with the population identification information. Thus, by referring to the population information PI, the game elements forming the normal population are specified. Alternatively, the population information PI may be a list or table in which information specifying game elements included in each of the selected population and the normal population, such as game element names, is set. Additionally, the population information PI may include information indicating the lottery probability of each of the plurality of game elements.

A plurality of game elements forming at least one of the selected population and the normal population may be automatically set by the server 20 for each lottery instead of being set in advance. Further, at least one of the plurality of game elements may be a user-selected game element. Also, the selection population may be set for each element type of a plurality of game elements. That is, a plurality of game elements forming at least one selection population may be unified so as to belong to a predetermined element type. This allows the user to select a selection population for each element type and collect game elements for each element type. The element type corresponds to the type of game element, such as character, rarity, version, attribute, and parameter. For example, if the genders of the game elements are different, the attribute, which is the element type, is different. It should be noted that game elements having partially the same element type belong to at least that element type.

Also, the normal population may be set to include specific game elements associated with the first lottery probability. The selection population may also be set to include specific game elements associated with a second lottery probability that is lower than the first lottery probability. As an example, the specific game element is a game element included in the population when a limited-time event is held. For example, if an event can be favorably advanced by using a character included in a particular dance unit, the character's digital card is the particular game element. In the normal population, the winning probability of the specific game element is set high so that such a specific game element is more likely to be won in the normal lottery. On the other hand, in the selection population, the probability of winning a specific game element is set lower than that in the normal population so that various game elements are likely to be won in the selection lottery. As a result, in the selection lottery, the winning probability of game elements other than the specific game element can be relatively increased. The first lottery probability and the second lottery probability can be included in population information PI.

The server storage unit 22 also stores play data PD including progress information indicating the degree of progress of the game unique to each user. For example, progress information is a viewable flag for each story. Alternatively, the progress information may be indicators such as play time, number of logins, level, number of items owned, and item earnings history. In addition, progress is divided into a plurality of stages. Furthermore, the play data PD includes information on the past play performance of each user. For example, the play data PD is used to hand over the past results, which are the play results up to the last time, from the next time onward, or to hand over the settings unique to each user. In addition, the play data PD includes various types of information such as the amount of in-game currency possessed and the amount of items possessed. The play data PD is associated with user identification information unique to each user, such as a user ID.

Further, the server storage unit 22 stores game data GD1 used when providing the game. The game data GD1 includes data used in the music game, such as sequence data, music data, music data, video data, and image data. For example, the moving image data includes a dance moving image and is an animation that is reproduced during a music game. Alternatively, the motion of the character in the dance animation may be realized by the terminal program PG2 based on the animation data. Also, the dance video may be configured as a video in which a virtual three-dimensional space is captured by a virtual camera. In this case, the shooting direction and angle of view of the virtual camera may be changed as appropriate, and the shooting position of the virtual camera may be changed. At least part of the game data GD1 is distributed by the server control unit 21 to the game machine 30 through a distribution service.

The sequence data also describes each execution timing at which game operations by the user should be executed in the music game. When the user performs a game operation, the game operation is evaluated based on the execution timing of the sequence data. Also, in the game machine 30, the timing of execution is guided based on the sequence data. In a music game, when a plurality of songs or a plurality of difficulty levels are prepared, sequence data is prepared for each song or difficulty level. For example, the sequence data includes route and type information in addition to execution time. A path is a moving path of an object indicating a position where the user should perform a touch operation. As an example, the routes are distinguished by numbers, and each number is described in the sequence data as route information. The type is the type of object, and for example, information for distinguishing the type of object is described in the sequence data as type information.

The server control unit 21 is wired or wirelessly connected to an interface including a keyboard or various switches for inputting predetermined commands and data. The server control unit 21 is wired or wirelessly connected to a monitor that displays the input state, setting state, measurement results, and various information of the device. Furthermore, the server control unit 21 is a portable recording medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), a CF (Compact Flash) card, and a USB (Universal Serial Bus) memory, or a server on the Internet. Control can also be performed according to a program stored in an external storage medium.

The server control unit 21 also acquires information about the user's input operation from the game machine 30, and executes various calculations necessary to progress the game according to the acquired information. Then, necessary information is transmitted to the game machine 30 in order to reflect the execution result in the game being played on the game machine 30 . For example, the server control unit 21 transmits game information necessary for the game machine 30 to provide the user with a game to the game machine 30 . For example, the game information is game data GD2. The game machine 30 then stores the received game data GD2.

The selection unit 23 of the server control unit 21 causes the game machine 30 to display a selection screen 60 for accepting a selection operation by the user. That is, the selection unit 23 causes the game machine 30 to display the candidate icons 61A, 61B, and 61C.

Alternatively, the selection unit 23 may acquire from the game machine 30 information identifying the game elements selected by the user to form the selection population or information identifying element types.

Here, the selection unit 23 displays the selection screen 60 before the selection lottery is performed. For example, the selection unit 23 displays the selection screen 60 before starting the continuous lottery, or during the continuous lottery and after the normal lottery ends. For example, the selection unit 23 displays the selection screen 60 before the final selection lottery. As an example, when the final lottery of the lotteries performed three times is the selection lottery, the selection unit 23 selects the selection lottery after the second normal lottery is executed and the lottery result is displayed, and before the selection lottery. to display the selection screen 60. Thereby, the user can refer to the results of the normal lottery to select the selection population.

The lottery unit 24 of the server control unit 21 executes consecutive lotteries so as to include normal lotteries and selective lotteries. In addition, the lottery section 24 draws at least one game element from a normal population including a plurality of game elements in the normal lottery. Furthermore, in the selection lottery, the lottery unit 24 draws at least one game element from the selection population selected by the user. And the lottery part 24 will transmit a lottery result to the game machine 30, if a continuous lottery is performed. In the continuous lottery, the normal lottery and the selection lottery are continuous at least once. For example, when three lotteries are held, the normal lottery is followed by the selection lottery pattern, the selection lottery is followed by the normal lottery pattern, the selection lottery followed by the normal lottery is followed by the normal lottery pattern, and the selection lottery pattern is followed by the normal lottery. Next, there is a pattern such as selection lottery.

Also, the lottery unit 24 may perform consecutive lotteries so that the selection lottery is performed last. For example, the lottery unit 24 executes the selection lottery for the third time when three lotteries are performed in the continuous lottery. Specifically, after executing two normal lotteries, the selection unit 23 causes the game machine 30 to display the selection screen 60 in order to execute the selection lottery. Then, the selection unit 23 acquires the population identification information for identifying the selection population selected by the user from the game machine 30 and transfers it to the lottery unit 24 . After that, the lottery section 24 draws a game element from the selection population selected by the user. Thereby, the user can refer to the lottery result of the normal lottery and select the selection population.

The authentication section 25 of the server control section 21 acquires user authentication information from the game machine 30 .
