  There is a game system that includes a display device that displays a game screen and provides a game including a lottery opportunity for giving a privilege through the game screen. In addition, such a game system may include a server device that manages a plurality of decks accommodating a plurality of game media so as to be individually assigned to a plurality of users. As such a server device, there is known a server device that gives a user a game medium selected from each deck while deleting it from the deck, and uses the deck from which the game medium has been deleted at the next selection. (For example, refer to Patent Document 1).

Japanese Patent No. 5335969

  In the server device of Patent Document 1, since each deck is individually assigned to each user, each user can always obtain the target game medium with the deletion of the selected game medium. That is, since each deck is dedicated to each user, there is no competition between users. As a result, it may lead to a factor that loses motivation for the opportunity to select the game media. There is a high possibility that it will not lead to motivation for at least such an opportunity, and thus to play the game early.

  Therefore, an object of the present invention is to provide a game system or the like that can promote the use of an early lottery opportunity.

  The game system of the present invention is a game system that provides a game including a lottery opportunity for granting a privilege through a game screen, and the lottery opportunity is sequentially given to each user for a plurality of users until an end condition is satisfied. When the termination condition is not satisfied in one lottery opportunity among the lottery opportunities, the expected value indicating the degree of expectation regarding the grant of the bonus is increased compared to the one lottery opportunity As described above, an expected value changing means for changing the expected value of the next lottery opportunity following the one lottery opportunity is provided.

  On the other hand, the computer program of the present invention is configured to cause a computer to function as each means of the above-described game system. The server device of the present invention is connected to a display device that displays the game screen via a network and functions as each unit of the above-described game system.

  Hereinafter, a game system according to an embodiment of the present invention will be described. FIG. 1 is a diagram showing an outline of the overall configuration of a game system according to an embodiment of the present invention. As shown in FIG. 1, the game system 1 includes a center server 2 and a game machine GM. The game machine GM is connected to the center server 2 via the network 3. As an example, the game machine GM is configured as a business (commercial) game machine. Commercial game machines are game machines that allow a predetermined range of games to be played for a fee or free of charge. As an example, the game machine GM provides a music game for a fee. Specifically, the game machine GM, for example, provides a music game in a range corresponding to the price in exchange for consumption of a predetermined price. An appropriate number of game machines GM are installed in a commercial facility such as the store 4.

  The center server 2 is not limited to an example constituted by a single physical device. For example, one logical center server 2 may be configured by a server group as a plurality of physical devices. Further, the center server 2 may be logically configured using cloud computing. Furthermore, the game machine GM may function as the center server 2.

  A user terminal 5 is connected to the center server 2 via the network 3. The user terminal 5 is a type of network terminal device that exhibits various functions by executing software distributed from the center server 2. In the example of FIG. 1, a mobile phone (including a smartphone) is used as an example of the user terminal 5. In addition, as the user terminal 5, for example, various network terminal devices that can be connected to the network and are used for personal use of the user, such as a personal computer, a portable game machine, and a portable tablet terminal device, are used. Good.

  As an example, the network 3 may be configured to realize network communication using a TCP / IP protocol. Typically, the network 3 may be configured by combining the Internet as a WAN and an intranet as a LAN. In the example of FIG. 1, the center server 2 and the game machine GM are connected to the network 3 via the router 3a, and the user terminal 5 is connected to the network 3 via the access point 3b.

  The network 3 is not limited to a form using the TCP / IP protocol. As the network 3, various forms using a wired line for communication or a wireless line (including infrared communication, short-range wireless communication, etc.) may be used. Alternatively, the communication between the user terminal 5 and the game machine GM or the like conforms to a predetermined standard so as to include various information such as a two-dimensional code without using a communication line (including wired and wireless), for example. It may be realized using a code (for example, a two-dimensional code) generated in this way. Therefore, the term “network (or communication line)” includes a form of transmitting and receiving information without using a line, such as a communication method using such a code.

  The center server 2 provides various game machine services to the game machine GM or its user. For example, a service for receiving user identification information from the game machine GM and authenticating the user may be provided as the game machine service. Further, a service may be provided in which the play data of the authenticated user is received from the game machine GM and stored, or the play data to be stored is provided to the game machine GM. Furthermore, the game machine service distributes and updates the game machine GM program or data via the network 3, and matches users when a plurality of users play a common game via the network 3. A matching service or the like may be included.

  Further, the center server 2 provides various Web services to the user of the user terminal 5 via the network 3. The web service may include, for example, a game information service that provides various types of information related to a game provided by the game machine GM. Further, for example, the web service may include a distribution service that distributes various data or software to each user terminal 5 (including updates of data and the like). Further, the Web service may include other services such as a community service that provides a place for information exchange, exchange, and sharing by users, and a service that provides a user ID for identifying each user.

  FIG. 2 is a diagram illustrating an appearance of the game machine GM. As shown in FIG. 2, the game machine GM includes a housing 6. A monitor 8 as a display device is provided on the upper surface of the housing 6. The monitor 8 may be arranged so as to be inclined toward the user P, for example. A transparent touch panel 9 is superimposed on the surface of the monitor 8. The touch panel 9 is a known input device that outputs a signal corresponding to the contact position when the user P touches with a finger or the like. In addition to the above, the game machine GM includes various input devices and output devices that are included in a normal business game machine such as a button for selecting or determining, a power switch, a volume operation switch, and a power lamp. Can be provided. However, those illustrations are omitted.

  For example, the game screen 7 may be displayed on the monitor 8. A music game may be provided through such a game screen 7. A music game is a type of timing game. Specifically, the timing game is a type of game that evaluates the execution time of an appropriate play action. In the music game, the execution time when such an appropriate play action is to be executed is provided together with the music. In the music game, the time coincident with the rhythm of the music is used as the execution time. In other words, the music game is a type of game that guides the user when an appropriate play action should be performed in accordance with the rhythm of the music and evaluates the time when the play action is actually executed. Further, for example, a plurality of music pieces may be prepared for play in a music game, and a music piece selected from them may be used for actual play.

  The game screen 7 may include, for example, an object image OJ and a determination line image HL. The object image OJ is an image for guiding the timing of an appropriate touch operation on the touch panel 9. For example, the object image OJ may be displayed to indicate an execution time when an appropriate play action should be executed. On the other hand, the determination line image HL is an image that functions as a destination of the object image OJ. For example, the determination line image HL may function as a reference for the current time in a music game. For example, on the game screen 7, an appropriate operation time may be guided through the arrival of the object image OJ to the determination line image HL.

  Specifically, the determination line image HL may include, for example, a first determination line image HL1 and a second determination line image HL2. That is, the object image OJ may move so as to reach the first determination line image HL1 or the second determination line image HL2 at the operation time, and guide the execution time when an appropriate play action should be executed by reaching these. . Further, for example, as an appropriate play action, a touch operation on the arrival position of the object image OJ on the determination line image HL where the object image OJ has reached may be employed. Then, for example, the object image OJ may move so as to reciprocate between the first determination line image HL1 and the second determination line image HL2, and appropriately guide the execution time. As an example, such a game screen 7 may be displayed on the monitor 8, and a music game may be provided through such a game screen 7.

  Next, the main part of the control system of the game system 1 for realizing a music game will be described. FIG. 3 is a diagram illustrating a configuration of a main part of the control system of the game system 1. As shown in FIG. 3, the center server 2 includes a control unit 10 and a storage unit 11. The control unit 10 is configured as a computer unit combining a microprocessor and various peripheral devices such as an internal storage device (for example, ROM and RAM) necessary for the operation of the microprocessor. Note that an input device such as a keyboard and an output device such as a monitor can be connected to the control unit 10. However, those illustrations are omitted.

  The storage unit 11 is connected to the control unit 10. The storage unit 11 is configured by a large-capacity storage medium such as a magnetic tape, for example, so that the storage can be held without power supply. The storage unit 11 stores server data 14 and a server program 15. The server program 15 is a computer program necessary for the center server 2 to provide various services to the game machine GM and the user terminal 5. When the control unit 10 reads and executes the server program 15, a game machine service management unit 16 and a web service management unit 17 are provided inside the control unit 10.

  The game machine service management unit 16 executes a process for providing the game machine service described above. On the other hand, the web service management unit 17 executes processing necessary to provide the above-described web service. The game machine service management unit 16 and the web service management unit 17 are logical devices realized by a combination of computer hardware and a computer program. Various other logical devices may be provided inside the control unit 10. However, those illustrations are omitted.

  The server data 14 is data that is referred to when the server program 15 is executed. For example, the server data 14 may include play data 18. The play data 18 is data in which information related to past play results of each user is described. The play data 18 is used, for example, to take over the previous play results (past results) from the next time onward, or to take over the settings specific to each user. Details of the play data 18 will be described later.

  In addition, the server data 14 may include various data for realizing a music game. For example, such data may include ID management data. The ID management data is data for managing various IDs such as user IDs. However, those illustrations are omitted.

  On the other hand, the game machine GM is provided with a control unit 30 as a computer, a storage unit 31, a reader 32, a touch panel 33, a monitor MO, and a speaker SP. The storage unit 31, the reader 32, the touch panel 33, the monitor MO, and the speaker SP are all connected to the control unit 30. The control unit 30 is configured as a computer unit in which a microprocessor and various peripheral devices such as an internal storage device (for example, ROM and RAM) necessary for the operation of the microprocessor are combined.

  In addition, various devices can be connected to the control unit 30 in the same manner as other known game machines, for example. Such devices may include, for example, various output devices or various input devices that can be provided in a known game machine GM. In addition, for example, such an input device may include a known device for collecting a predetermined value such as a coin authentication device. For example, coins or the like as a predetermined price may be collected through such a device. However, those illustrations are omitted.

  The touch panel 33 is a known input device as described above. For example, the touch panel 33 may output a signal corresponding to the touch position to the control unit 30 based on a user's touch operation. The monitor MO is a known display device for displaying various images and the like based on an output signal from the control unit 30. As an example, the monitor MO may display the game screen 7 as described above according to the output signal from the control unit 30. Similarly, the speaker SP is a well-known output device (sound reproduction device) for reproducing various sounds based on an output signal from the control unit 30. The speaker SP may reproduce various sounds used in a music game, such as music and BGM, according to an output signal from the control unit 30, for example.

  The reader 32 is a known device that reads various information recorded in a storage medium in a non-contact state, for example, using short-range wireless communication. The reader 32 may be used for reading information on a card CD as an example of a storage medium. Specifically, as an example, the reader 32 may read information on a card CD possessed by each user and output a signal corresponding to the information to the control unit 30.

  The card CD may be provided with a non-volatile storage medium (not shown) such as an IC chip or a magnetic stripe. Various types of information may be recorded on the card CD via such a nonvolatile storage medium. For example, various types of information may include user ID information (including information that can identify the user ID). That is, the card CD may be used for specifying each user corresponding to the ID card, for example, as an ID card. Furthermore, the various types of information may include, for example, information on the amount of value used as a predetermined consideration (including information for specifying the amount of value). Then, a predetermined consideration may be collected by consuming the value amount. That is, the card CD may be used for payment of a predetermined price as an example.

  The card CD is not limited to a form in which various types of information are electronically recorded. For example, the card CD may record various information via various codes such as a two-dimensional code. In this case, the reader 32 may be configured to be able to read such a code by including a code reader capable of reading such a code. That is, the reader 32 may be used for reading such a code.

  On the other hand, the storage unit 31 is configured by, for example, a magnetic recording medium, an optical recording medium, a flash SSD (Solid State Drive), or the like so that the storage can be held without supplying power. The storage unit 31 stores a game program 34 and game data 35. The game program 34 is a computer program necessary for the game machine GM to provide a music game. Along with the execution of the game program 34, a game providing unit 37 is provided inside the control unit 30. The game providing unit 37 executes various processes necessary for providing a music game. The game providing unit 37 is a logical device realized by a combination of computer hardware and a computer program. Various other logical devices may be provided inside the control unit 30. However, those illustrations are omitted.

  The game data 35 is data that is referred to when the game program 34 is executed. The game data 35 includes, for example, play data 18, music data 36, sequence data 38, and lottery data 39. The play data 18 is as described above. As an example, at least a part of the play data 18 may be provided from the center server 2 so that a necessary part is included.

  The music data 36 is data necessary for causing the speaker SP to reproduce various sounds such as music used in the music game. The sequence data 38 is data necessary for guiding the user when to perform an appropriate play action in the music game. For example, the sequence data 38 may describe in advance an operation time when an appropriate position is to be touched. For example, in a music game, the position and time when an appropriate touch operation should be performed may be guided based on each operation time described in the sequence data 38. The lottery data 39 may be used to provide a lottery opportunity described later in a music game, for example. The details of the lottery data 39 will be described later in the same manner as the play data 18.

  The game data 35 may include various other data for executing a music game. For example, such data may include image data and the above-described ID management data. The image data is data for displaying various images necessary for the game. However, those illustrations are omitted.

  Next, a flow of a music game provided by the game machine GM will be described with reference to FIG. FIG. 4 is an explanatory diagram for explaining an example of the flow of a music game. As shown in FIG. 4, as an example, the music game may include a music selection step (S1), a play step (S2), and a lottery step (S3) in this order.

  The music selection process is a process for allowing the user to select music used for playing the music game (S1). The subsequent play process is a process for allowing the user to play the music game (S2). For example, the play process may be provided through the game screen 7 as described above. The music game may be provided so that the music selected in the music selection process is used for play.

  The next lottery step is a step of providing a lottery opportunity for giving various benefits to the user (S3). In addition, a lottery process is not limited to the form provided after a play process. For example, the lottery process may be provided at an appropriate time such as before the play process or before the music selection process. In addition, such time may include other processes such as during the playing process. That is, for example, the lottery process may be provided in another process such as a play process. Further, the lottery process may be provided for each user one by one or may be provided for a plurality of users at the same time.

  Next, the details of the lottery opportunities provided in the lottery process will be described with reference to FIGS. FIG. 5 is an explanatory diagram for explaining an example of a lottery opportunity provided in the lottery process. As shown in FIG. 5, the lottery opportunities of the music game are managed in units of lottery sets LG configured as a set of a plurality of lottery opportunities L, for example, and are provided to the user group PG in units of the lottery sets LG. Good. Each lottery set LG may be sequentially provided to each user group PG, for example. Further, for example, the lottery set LG may be provided such that each lottery opportunity L constituting the lottery set LG is sequentially provided to each user P of the user group PG. In addition, each lottery set LG has a new lottery set LG (next lottery set LG) that is a new user group PG when, for example, an end condition is satisfied (if equipped) at a lottery opportunity using each lottery set LG. It may be provided in order so as to be provided to (next user group PG).

  Specifically, for example, the lottery opportunity of the music game may include the first lottery set LG1 and the second lottery set LG2 as the lottery set LG. The first lottery set LG1 is a lottery set LG provided for the first user group PG1. The first lottery set LG1 may include, for example, a first lottery opportunity L1, a second lottery opportunity L2, and an Nth lottery opportunity LN as a plurality of lottery opportunities L. For example, when a lottery process is provided to one user P in order for each opportunity to play a music game, these may be provided to the user P who uses each lottery process in order. And the user P who uses each lottery process which provides each lottery opportunity L of these 1st lottery opportunities L1, the 2nd lottery opportunity L2, and the Nth lottery opportunity LN, ie, the 1st lottery set LG1, in order is the 1st user. You may function as each user P1 which forms group PG1.

  More specifically, the first lottery opportunity L1 is the lottery opportunity L provided first among the lottery opportunities L included in the first lottery set LG1. Therefore, for example, the first lottery opportunity L1 may be provided to the first user P1a who first uses the first lottery set LG1 among the users P1 that form the first user group PG1. That is, the user P to whom the first lottery process using the first lottery set LG1 is provided may function as the first user P1a of the first user group PG1.

  The end condition may be determined for each lottery opportunity L of the first lottery set LG1, for example. For example, when the end condition is satisfied (if equipped) in the first lottery opportunity, the use of the first lottery set LG1 is finished, and the lottery using the second lottery set is started from the next time. Good. That is, the lottery process using the first lottery set LG1 ends at this time (first first user P1a), and the second lottery set LG2 may be provided to each user P in the next lottery process. In this case, only the first user P1a functions as the first user group PG1. That is, the first user group PG1 does not include other than the first user P1a. As described above, as long as the user group PG such as the first user group PG1 can be provided for a plurality of users P, as a result, the user group PG may be configured to correspond to only one user P instead of the plurality of users P. . The same applies to each lottery set LG. Specifically, for example, each lottery set LG may be configured only by the first lottery opportunity L1. That is, the user group PG and the lottery set LG are merely concepts that can include a plurality of users P or a plurality of lottery opportunities L, and do not necessarily include a plurality of users P or a plurality of lottery opportunities L. .

  In addition, the termination condition may be satisfied, for example, when a privilege is granted. That is, the lottery set LG such as the first lottery set LG1 may be configured as, for example, a set of a plurality of lottery opportunities L to which a common privilege is to be given through such an end condition. Further, the number of benefits to be granted may be an appropriate number such as singular or plural. For example, when the number of benefits to be granted is singular, the termination condition may be satisfied when the one privilege is granted. That is, the provision of the lottery process using the first lottery set LG1 may be terminated with the provision of one privilege. And in the lottery process after the next time, the 2nd lottery set LG2 containing the some lottery opportunity L which makes a common privilege the subject of grant may be provided.

  On the other hand, when the number of benefits to be granted is plural, for example, the end condition may be satisfied when all the privileges to be granted are granted. That is, for example, each lottery opportunity L of the first lottery set LG1 is configured to sequentially grant one of a plurality of benefits, and the termination condition may be satisfied when all the benefits have been granted. Alternatively, the end condition may be satisfied when a specific privilege (for example, a privilege with the highest value, etc.) is granted among a plurality of benefits to be granted. In this case, even if each privilege is given one by one in each lottery opportunity, all the privileges may be used as the subject of grant every time in each lottery opportunity L. Further, the privilege to be granted may be selected by the user from a list or the like, for example.

  On the other hand, the second lottery opportunity L2 may be provided in the next lottery process when, for example, the end condition is not satisfied in the first lottery opportunity L1. That is, the second lottery opportunity L2 may be provided to the user P of the second lottery process using the first lottery set LG1. In this case, the user P in the second lottery process may function as the second user P1b who uses the first lottery set LG1 second among the users P1 that form the first user group PG1.

  Further, the second lottery opportunity L2 may be provided such that an expectation value indicating a degree of expectation regarding the grant of the privilege is increased as compared with the first lottery opportunity L1. Specifically, for example, a bonus winning probability (probability of granting a privilege) may be used as the expected value. That is, for example, the second lottery opportunity L2 may be provided so that the winning probability of the privilege is higher than that of the first lottery opportunity L1.

  The lottery opportunity L after the second lottery opportunity L2 may be provided in the same manner as the second lottery opportunity L2. For example, the Nth lottery opportunity LN may be provided to the user P in the lottery process that uses the first lottery set LG1 Nth. In other words, the Nth lottery opportunity LN is determined, for example, when the end condition is not satisfied in the previous lottery opportunity L (the N-1 lottery opportunity corresponding to the N-1 first lottery opportunity L (not shown)). It may be provided in the process. The user P in the Nth lottery process may function as the Nth user P1n who uses the first lottery set LG1 among the users P1 that form the first user group PG1. That is, a set of N users P who sequentially use N lottery processes in which the first lottery opportunity L1, the second lottery opportunity L2, and the Nth lottery opportunity LN of the first lottery set LG1 are sequentially provided is the first. It may function as one user group PG1.

  The same applies to the expected value. That is, each lottery opportunity L may be provided such that the expected value gradually increases as the value of N increases, such as the second lottery opportunity L2 rather than the first lottery opportunity L1. Specifically, the Nth lottery opportunity LN may be provided so that the winning probability of the privilege increases as the value of N increases. Note that an appropriate number may be applied to the numerical value of N afterwards in accordance with the number of lottery processes that use the first lottery set LG1. That is, N lottery opportunities L are provided in order until the end condition is satisfied, and as a result, they may function as the first lottery set LG1.

  On the other hand, when the end condition is satisfied, the expected value may be reset and provision of the second lottery set LG2 may be newly started. For example, the second lottery set LG2 may be configured similarly to the first lottery set LG1. That is, for example, the second lottery set LG2 includes a first lottery opportunity L1, a second lottery opportunity L2, and an Nth lottery opportunity LN, which may be sequentially provided in each of the N lottery steps. A set of N users P using these N lottery processes may function as the second user group PG2. In other words, each lottery set LG may function as a set of a series of lottery opportunities L in which the expected value continuously increases in order. As an example, each such lottery opportunity L may be provided in each lottery process. In this case, the first lottery opportunity L1 (or the N-1th lottery opportunity) is one lottery opportunity of the present invention, and the second lottery opportunity L2 (or the Nth lottery opportunity LN) is the next lottery opportunity of the present invention. As each function.

  Note that the expected value of the first lottery opportunity L1 of the second lottery set LG2 may be set as appropriate. For example, it may be the same as the first lottery opportunity L1 of the first lottery set LG1. Alternatively, it may be different from the first lottery opportunity L1 of the first lottery set LG1, such as higher or lower than the first lottery opportunity L1 of the first lottery set LG1. Also, the number of lottery sets LG may be set appropriately afterwards according to the number of benefits to be granted.

  Each lottery opportunity L may be provided through a lottery screen displayed on the monitor MO, for example. FIG. 6 is a diagram schematically illustrating an example of a lottery screen 50 for providing each lottery opportunity L. As illustrated in FIG. 6, for example, the lottery screen 50 may include an option area 51, a privilege information area 52, and an expected information area 53.

  The option area 51 is an area for displaying a plurality of option images 51a. The plurality of option images 51a function as options (lottery targets) to be selected by each user P. For example, a privilege is associated with at least a part of the plurality of option images 51a, and when the option image 51a associated with such a privilege is selected by the user P, the privilege associated with the option image 51a is given to the user P. May be granted.

  The privilege information area | region 52 is an area | region for displaying the content of the privilege of grant object. For example, music that can be used in a music game may be used as a privilege. Specifically, the music game includes, for example, special music that can be used (selectable) only by users who have the right to use (special rights) as music candidates for play, and such special music is used as a privilege. May be. In other words, the right to use special music may be used as a privilege.

  The expected information area 53 is an area for displaying information regarding expected values. In the expected information area 53, for example, information on the number of option images 51a (that is, the number of options) and the number of winning items (the number of benefits) may be displayed as such information.

  In the example of FIG. 6, 30 box-type option images 51 a are displayed in the option area 51. In addition, all the option images 51a can be selected. That is, it corresponds to an example of the lottery screen 50 for providing the first lottery opportunity L1 of each lottery set LG. On the other hand, in the current lottery opportunity L, selection of the option image 51a located in the lower right of the 30 option images 51a is scheduled. Similarly, in the expectation information area 53, “30 remaining BOX information” as information on the number of option images 51a and “two hits” information as information on the number of winning items are displayed. Thereby, it is guided that the privilege is associated with two of the 30 option images 51a in the option area 51. In the privilege information area 52, information such as “MUSIC A” indicating the contents of the special music is displayed. In this case, a bonus is won with a probability of 2/30, and a special music corresponding to “MUSIC A” is given along with the winning.

  FIG. 7 is a diagram schematically illustrating an example of a lottery screen 50 for providing the second lottery opportunity L2 of each lottery set LG. More specifically, the example of FIG. 7 shows an example of the lottery screen 50 used in the lottery process after the option image 51a located at the lower right is selected on the lottery screen 50 of FIG. As shown in FIG. 7, in the second lottery opportunity L2 following the first lottery opportunity L1 in the example of FIG. 6, the lower right option image 51a (broken line in the example of FIG. 7) disappears with the selection of the user P. (A broken line is not displayed on the actual lottery screen 50). As a result, the number of option images 51a has decreased from 30 in the previous (first lottery opportunity L1) to 29. On the other hand, the number won (“2”) does not change because it was not won last time. Therefore, the current winning probability is calculated as 2/29. In other words, the winning probability (expected value) has increased from 2/30 to 2/29.

  As an example, a lottery opportunity L for each lottery process may be provided through the lottery screen 50 as described above. Specifically, as an example, the lottery may be realized by the user P selecting any one from the set of option images 51a as described above. Then, the expected value may increase due to the disappearance of the selected option image 51a in the lottery opportunity L up to the previous time. More specifically, the set of option images 51a is used so that the set of option images 51a in which the already selected option images 51a are excluded in the previous lottery opportunities L are used in the next lottery opportunity L. By displaying (setting) on the lottery screen 50 of the next lottery process, the expected value may be increased. In this case, the option image 51a functions as the lottery element of the present invention, and the lower right option image 51a selected by the user P in the example of FIG. 6 functions as the selected lottery element of the present invention. The set of option images 51a in the example of FIG. 6 (all option images 51a in the option area 51) is the first element set of the present invention, and the set of option images 51a of the example of FIG. 7 is the second element of the present invention. Each functions as a set.

  Note that the number of option images 51a that can be selected in each lottery opportunity L may be appropriate. That is, for example, for each lottery opportunity L, a plurality of option images 51a such as two or three may be selected. In addition, the winning position (the option image 51a associated with the privilege) may be the same every time (for example, the same in each lottery opportunity L of the lottery set LG) or may be changed as appropriate.

  Similarly, the content of the privilege may be common in the unit of the lottery set LG, or may be different in the unit of the lottery opportunity L. When they are different, the content of the privilege may change based on the change condition, for example. The change condition may include, for example, a play situation of a music game such as a privilege grant situation and an attribute of the user P. That is, the content of a privilege may change according to the play situation of the music game including the winning situation of the privilege or the attribute of the user P, for example. For example, age, sex, etc. may be used as an attribute of the user P. That is, the content of a privilege may change according to a user's age, sex, etc. Specifically, for example, genders such as special music for teenagers, special music for 20s, etc. according to the age (for example, age) of user P, special music for men, special music for women, etc. Depending on the attribute of the user P, a special musical piece with content corresponding to the user P may be used as a privilege.

  Further, for example, ownership information indicating whether or not the privilege to be granted is already provided may be used as the play status. Specifically, for example, when the user P already has the right to use the special song to be granted, the privilege to be given may be changed to a special song different from the special song. Moreover, when a some privilege exists as grant object, such a change may be performed in the part. Alternatively, in the case where all of the options are associated with any privilege, such as a change advantageous to the user P, the privilege that is owned may be excluded from the options. That is, at each lottery opportunity L, for example, a lottery may be executed for a group of options (a set of options) excluding options associated with the privilege that is owned. In this case, the options associated with such owned benefits function as the corresponding lottery elements of the present invention, and the option groups from which such options are excluded function as the third element set of the present invention.

  Further, the information on the expected value may be displayed not only on the lottery screen 50 but also on a standby screen that is displayed while waiting for the next music game to be played. That is, information on the expected value of the next lottery opportunity L such as the winning probability may be notified to a play candidate who may play the music game next time.

  FIG. 8 is a diagram schematically illustrating an example of a standby screen displayed during standby. As shown in FIG. 8, the standby screen 60 may include an expected notification area 61, for example. The expectation notification area 61 is an area for notifying information on the expected value of the next lottery process. For example, when the winning probability is used as the expected value, information on the number of options used in the next lottery process may be displayed in the expected notification area 61 as information related thereto.

  The example of FIG. 8 corresponds to an example of the standby screen 60 when the second lottery opportunity L2 (the lottery opportunity L in which the lottery screen 50 of the example of FIG. 7 is used) is provided in the next lottery process. For this reason, in the example of FIG. 8, “29 remaining information” indicating the number of option images 51 a displayed on the lottery screen 50 (example of FIG. 7) used in the next lottery process is displayed. As an example, such a standby screen 60 may be displayed during standby. Then, information relating to the expected value of the next lottery process may be notified to the surroundings (candidate users who will play the next music game) through such a standby screen 60.

  Next, details of the play data 18 and the lottery data 39 will be described. The lottery data 39 is data for providing each lottery opportunity L for each lottery set LG as described above. FIG. 9 is an explanatory diagram for explaining an example of the contents of the lottery data 39. As shown in FIG. 9, the lottery data 39 includes, for example, information on “lottery ID”, “privilege”, “number of choices”, “winning number”, “winning position”, “selected position”, and “end”. May contain.

  “Lottery ID” is information of a unique ID for each lottery set LG. The “lottery ID” information is used to identify each lottery set LG. “Bonus” is information indicating the content of the privilege used as the grant target at each lottery opportunity L. For example, when a special music is used as a privilege, a music ID indicating the special music (a unique ID for each music) may be used as “privilege” information.

  “Number of options” is information indicating the number of options (for example, option images 51a) to be displayed in the first lottery opportunity L, that is, the first lottery opportunity L1. For example, when 30 option images 51a are displayed in the first lottery opportunity L1, information of “30” may be used as information of “number of options”.

  The “winning number” is information indicating the number of benefits to be granted. For example, when a privilege is associated with two option images 51a out of 30 option images 51a, information “2” may be used as the “winning number”. Further, when a plurality of benefits are prepared, information on the “winning number” may be described for each benefit (for each “privilege” record). The same applies to “winning position” and “selected position”.

  “Winning position” is information for specifying an option associated with a privilege among the options. For example, when the 30 option images 51a in the example of FIG. 6 are used as options, the option images 51a at each position may be specified by numbering (numbering) sequentially from the upper left. A number (number) indicating the option image 51a at each position may be used as the “winning position” information.

  “Selected position” is information for specifying the position of an already selected option in the lottery opportunity L up to the previous time. For example, like the “winning position”, a number indicating the option image 51a at each position may be used as the “selected position”. If there are a plurality of selected options, the “selected position” may include information indicating a plurality of selected positions. As a result, the “selected position” may function as information for specifying the number of selected options. On the other hand, for example, in the case of the first lottery opportunity L, that is, when there is no lottery opportunity L up to the previous time, information indicating the first time such as “0” may be used as the “selected position”.

  “End” is information for determining whether or not the end condition is satisfied. For example, various types of information that can determine whether the end condition is satisfied or not such as “1” indicating that the end condition is satisfied and “0” indicating that the end condition is satisfied may be used as “end”. Specifically, for example, when the end condition is satisfied when the privilege is granted, “0” may be described as the “end” information until the privilege is granted, and “1” is associated with the grant. . As an example, the lottery data 39 is configured as a set of records described so that these pieces of information are associated with each other.

  On the other hand, as described above, the play data 18 is data for realizing inheritance of past results. FIG. 10 is an explanatory diagram for explaining an example of the contents of the play data 18. As shown in FIG. 10, the play data 18 includes, for example, information on “user ID”, “result data”, and “attribute data”.

  “User ID” is information of the above-mentioned user ID (ID for identifying each user). “Result data” is information for passing on past results in subsequent play. For example, the “result data” may include information of “game ID”, “selected music ID”, “play date / time”, “score”, and “banned music ID”.

  “Game ID” is information indicating a unique game ID for each game. The information of “game ID” is used to identify each game such as a music game. “Selected music ID” and “unlocked music ID” may be included, for example, when the information of “game ID” indicates a music game. In addition, for each of the “selected music ID” and the “banned music ID”, for example, unique music ID information may be used for each music for identifying each music used for playing the music game. . Specifically, the “selected music ID” is information on a music ID indicating a music selected for play in the music game. On the other hand, “banned music ID” is information of a music ID indicating a special music (banned music) owned by each user. For example, the information of “banned music ID” may function as a right to play a special music. The information of “banned music ID” may function as possession information. Further, “play date” corresponds to information on the date and time when each piece of music was played, and “score” corresponds to information on the score at that time.

  “Attribute data” is information indicating the attribute of each user. The “attribute data” may include information such as “sex” and “age”, for example. “Gender” corresponds to information indicating the gender of each user, and “age” corresponds to information indicating the age of each user. The “attribute data” may include, for example, information indicating the name and address of the user. As an example, the play data 18 may be configured as a set of records described so that these pieces of information are associated with each other.

  Next, details of the lottery process and the notification process will be described. The lottery process is a process for realizing the lottery process described above. In addition, the notification process is a process for notifying information about the expected value to the surroundings (candidate users who will play the next music game). For example, the lottery process may be realized by the control unit 30 of the game machine GM through the routine of FIG. 11 and the notification process through the routine of FIG. More specifically, the routines of FIGS. 11 and 12 may be executed through the game providing unit 37 of the control unit 30 as an example. Note that the control unit 30 of the game machine GM and the control unit 10 of the center server 2 execute various kinds of well-known processes alone or in cooperation with each other in addition to these processes. However, detailed description thereof will be omitted.

  FIG. 11 is a diagram illustrating an example of a flowchart of a lottery process routine for realizing the lottery process. More specifically, the example of FIG. 11 corresponds to an example of a flowchart of a lottery process routine for realizing the lottery process in the case where the content of the privilege is changed based on the ownership information of each user P. The routine of FIG. 11 may be executed, for example, when a lottery condition for providing a lottery process is satisfied. In addition, the lottery condition may be satisfied when the play process is completed, for example, when the lottery process is provided after the play process. That is, the routine of FIG. 11 may be executed with the end of the play process as an example.

  When the routine of FIG. 11 is started, the game providing unit 37 first acquires the lottery data 39 in step S11. In subsequent step S12, the game providing unit 37 determines whether or not the change condition is satisfied. The change condition is satisfied, for example, based on the ownership information of the target user P (user P to whom the lottery opportunity L is provided) as described above, when the user P owns the privilege to be granted. If the determination result is a positive result, that is, if the change condition is satisfied (the target user P owns the privilege to be granted), the game providing unit 37 proceeds to step S13.

  In step S13, the game providing unit 37 changes the content of the privilege to be granted. For example, as described above, this change may be realized by changing the original special song to be given to another special song that the user P does not own. Similarly, when the target user P owns only a part of the privilege to be granted, this change may occur in the part of the privilege.

  On the other hand, if the determination result in step S12 is a negative result, that is, if the change condition is not satisfied (the target user P does not own the privilege to be granted), and after executing the process in step S13, the game is provided The unit 37 proceeds to step S14. In step S14, the game providing unit 37 determines whether or not the end condition is satisfied. The end condition is satisfied, for example, when the privilege to be granted is granted as described above. In addition, for example, when the lottery data 39 includes “end” information, this determination may be performed based on this information. If the determination result is a negative result, that is, if the end condition is not satisfied (no privilege is given at the previous lottery opportunity L), the game providing unit 37 proceeds to step S15.

  In step S15, the game providing unit 37 provides a lottery process using the continuous lottery opportunity L. That is, the game providing unit 37 continues to use the same lottery set LG as in the previous (N-1 lottery opportunity), and provides the current lottery opportunity L (Nth lottery opportunity LN) following the previous lottery set LG. To do. More specifically, for example, a set of option images 51a excluding the selected option images 51a from the set of option images 51a used in the previous lottery opportunity L (for example, the example of FIG. 6) (for example, the example of FIG. 7). ) And displaying a lottery screen 50 (for example, the example of FIG. 7) that displays a set of such option images 51a, the game providing unit 37 provides a lottery process using the continuous lottery opportunity L. It's okay. Further, this display may be executed based on the lottery data 39 when the lottery data 39 includes information on “selected position”, for example.

  On the other hand, if the determination result in step S14 is an affirmative result, that is, if the end condition is satisfied (a privilege is given at the previous lottery opportunity L), the game providing unit 37 proceeds to step S16. In step S16, the game providing unit 37 provides a lottery process using a new lottery opportunity L different from the previous lottery opportunity L. Specifically, for example, the game providing unit 37 newly uses a lottery set (for example, the second lottery set LG2) different from the lottery set LG (for example, the first lottery set LG1) to which the previous lottery opportunity L belongs. The lottery opportunity L (for example, the 1st lottery opportunity L1) which starts and should be provided for the first time which belongs to this lottery set LG may be provided in a lottery process. That is, by using a lottery set LG different from the previous one, the current lottery opportunity L functions as the first lottery opportunity L (first lottery opportunity L1), not the continuation of the previous lottery opportunity L. Provide lottery process. More specifically, for example, by displaying a lottery screen 50 using a set of option images 51a that does not include the selected option image 51a, that is, a set of option images 51a that do not include the excluded option images 51a. The game providing unit 37 may provide a lottery process using the new lottery opportunity L. As a result, the game providing unit 37 may reset the expected value by this process.

  In subsequent step S <b> 17, the game providing unit 37 determines whether or not a privilege can be won. If the determination result is an affirmative result, that is, if the winning is possible (when the bonus is won), the game providing unit 37 proceeds to step S18. And the game provision part 37 provides a privilege to the user P in step S18, and progresses to step S19.

  On the other hand, when the determination result of step S17 is a negative result, that is, when the winning is not possible (when the bonus is not won), the game providing unit 37 skips step S18 and proceeds to step S19.

  In step S19, the game providing unit 37 updates the contents of the lottery data 39 so as to reflect the current processing result. For example, when the game providing unit 37 has given a privilege through the process of step S18, the game providing unit 37 skips the process of step S18 so as to indicate that the end condition is satisfied (that is, it is determined that the game is not won in step S17). In the case), the content of “end” may be updated to indicate that the end condition is not satisfied. Similarly, for example, when the end condition is not satisfied, the game providing unit 37 may specify the option selected in the lottery opportunity L in step S15 or step S16 (for example, the position of the selected option image 51a). The contents of “selected position” may be updated. And the game provision part 37 complete | finishes this routine, after finishing the process of step S19.

  According to the routine of FIG. 11, when the target user P already owns the privilege to be granted, the content of the privilege to be granted is changed. Further, when the end condition is not satisfied in the previous lottery opportunity L, the current lottery opportunity L belonging to the same lottery set LG is provided. That is, the next lottery opportunity L belonging to the same lottery set LG following the previous lottery opportunity is provided as the current lottery opportunity L. As a result, the lottery opportunity L changed so that the expected value is higher than the previous lottery opportunity L is provided as the current lottery process. More specifically, for example, in the current lottery process, the lottery screen 50 that does not include the option image 51a already selected in the previous lottery process is used. In other words, the current lottery process is provided so that the expected value is higher than the previous value by using the set of option images 51a excluding the selected option image 51a (in other words, the option of losing). On the other hand, when the end condition is satisfied in the previous lottery opportunity L, a lottery set LG different from the lottery set LG used in the previous lottery process is used, and the expected value is reset. That is, provision of each lottery process using another lottery set LG is started again from the first time.

  FIG. 12 is a diagram illustrating an example of a flowchart of a notification processing routine for realizing the notification processing. The routine of FIG. 12 may be executed with the display of the standby screen 60, for example. For example, the standby screen 60 may be displayed with the end of the provision of the music game (the range corresponding to the collected consideration). In addition, for example, the provision of the music game may end with the end of the lottery process. That is, as an example, the routine of FIG. 12 may be executed with the end of the lottery process.

  When the routine of FIG. 12 is started, the game providing unit 37 first acquires the lottery data 39 in step S21. In subsequent step S22, the game providing unit 37 acquires an expected value. This acquisition may be performed as follows, for example. That is, the game providing unit 37 first acquires information on “number of options” and “selected position” included in the lottery data 39 acquired in step S21. Next, the game providing unit 37 calculates the number of remaining options (for example, the option image 51a) from the information of the “number of options” and “selected position”. On the other hand, for example, when a new lottery set L is scheduled to be used in the next lottery process, the expected value is reset at the next lottery opportunity L, so the game providing unit 37 In other words, the game providing unit 37 may determine whether or not the previous lottery opportunity L is satisfied in step S22, for example, in step S22. Similar to S14, it may be executed based on the “end” information of the lottery data 39. Also, for example, the contents (the winning probability, etc.) of the lottery set LG used next time up to the previous time In the same manner as the selection set LG, the game providing unit 37 may acquire the “number of choices” information of the previous lottery set LG included in the lottery data 39 as the initial expected value, or the contents of each lottery set LG If there is data that defines the information, the information corresponding to the initial expected value may be acquired from the data, for example, the acquisition of step S22 may be executed in this way. In addition, 37 may acquire an expected value suitably by various methods according to the content of the expected value, etc. For example, when a winning probability is used as the expected value, the game providing unit 37 selects lottery data. The winning probability may be calculated by further using information on the “winning number” of 39. Further, the expected value is not limited to the calculated form, for example, the game providing unit 37 stores pre-stored table data. In other words, the expected value acquisition unit of the present invention is not limited to the form of acquiring the expected value by calculation, and the expected value is obtained from given data such as table data, for example. May be obtained.

  In the next step S23, the game providing unit 37 determines whether or not the notification condition is satisfied. The notification condition may be satisfied, for example, when the expected value is greater than or equal to a predetermined value. That is, as an example, the notification condition may be satisfied when the degree of expectation regarding the privilege is higher than a predetermined value. Specifically, for example, when the number of remaining options is used as the expected value, the notification condition may be satisfied when the number of remaining options is less than a predetermined number. For example, when the winning probability is used as the expected value, the notification condition may be satisfied when the winning probability is equal to or higher than a predetermined value. When this determination result is a negative result, that is, when the notification condition is not satisfied (when the expected value is less than the predetermined value), the game providing unit 37 skips the subsequent processing and ends the current routine. That is, in this case, notification of expected value information may be omitted. Specifically, for example, the standby screen 60 may not include the expected notification area 61. Or you may include the expectation notification area | region 61 where the information of expectation value is not displayed.

  On the other hand, if the determination result in step S23 is a positive result, that is, if the notification condition is satisfied, the game providing unit 37 proceeds to step S24. In step S24, the game providing unit 37 notifies the expected value calculated in step S22 to the surroundings. Specifically, the game providing unit 37 may notify the expected value information through the standby screen 60 by displaying the expected notification area 61 including the expected value information calculated in step S22, for example. And the game provision part 37 complete | finishes this routine, after finishing the process of step S24. Thereby, the information of the expected value of the next lottery process is notified to surrounding users, that is, users who have the possibility of playing the music game after the next time. Note that the notification condition may be omitted. That is, the expected value information may always be notified regardless of the content of the expected value.

  As described above, according to this embodiment, the lottery set LG configured by each lottery opportunity L is provided for a plurality of users P. That is, a series of lottery opportunities L whose expected values continuously increase in order are provided for a plurality of users P. Thereby, while being able to promote the competition between the users P, the expectation with respect to the next lottery opportunity can be raised. Specifically, for example, when the end condition is satisfied by granting a privilege, a lottery opportunity with a high expected value is provided to other users unless the music game (lottery process) is played early. Thereby, use of an early lottery opportunity, that is, play of a music game can be promoted.

  Further, when the termination condition is satisfied, the expected value is reset. For this reason, it can suppress that an expected value continues rising. In addition, the use of a lottery opportunity before resetting can be promoted. Thereby, the use of an early lottery opportunity, that is, the play of a music game can be further promoted.

  Further, when information on the expected value of the next lottery process is notified through the standby screen 60, information on the expected value of the next lottery process is given to surrounding users, that is, users who have a possibility of playing the music game next time. Can be recognized. Accordingly, for example, a user who originally does not plan to play a music game, such as a user who plays a music game due to expected value information, can be guided to the music game. As a result, the use of the music game can be further promoted, and the range of users competing for the use of the next lottery opportunity can be expanded to the range of users who are not originally scheduled to play. Further, when the notification condition is used, for example, notification of expected value information can be limited to a case where the expected value is a predetermined value or more. In this case, the usefulness of the expected value information can be improved. By these, utilization of an early lottery opportunity can be further promoted.

  In the above embodiment, the control unit 30 of the game machine GM functions as an opportunity providing unit and an expected value changing unit of the present invention by executing the routine of FIG. Further, the control unit 30 of the game machine GM functions as an expected value acquisition unit and an expected value notification unit of the present invention by executing the routine of FIG.

  This invention is not limited to the above-mentioned form, It can implement with a suitable form. For example, in the above-described form, the game machine GM provides a music game. However, the game provided by the game machine is not limited to such a game. For example, the game machine GM may provide various games such as an action game, a role playing game, a simulation game, a puzzle game, and a shooting game. That is, the lottery process (lottery opportunity L) described above may be applied to such various games.

  Similarly, in the above-described embodiment, an example in which special music is used as a privilege is described. However, the privilege is not limited to such an example. For example, depending on the type of game provided by the game machine GM, various game elements owned by the user or unrelated to the user, such as characters and background images used in various games, may be used as benefits. .

  Further, in the above-described form, for example, an example of a winning probability is described as the expected value. However, the expected value is not limited to such an example. For example, a plurality of benefits are prepared, and each privilege is identified by a value (for example, ownership rate, appearance rate, etc., or when a character is used as a privilege, the strength based on the character's level, parameters, etc.) In the case where the ones are different, a value indicating the value of the privilege may be used as the expected value. In addition, when a plurality of benefits are used as grant targets in each lottery opportunity L, values indicating the overall value of the plurality of privileges, such as an average value or a mode value of those values, are used as expected values. May be. Similarly, various values indicating the degree of expectation related to the granting of benefits may be employed as the expected value.

  Moreover, in the above-mentioned form, the termination conditions that are satisfied when a privilege is granted are illustrated. However, the termination condition is not limited to such an example. For example, the end condition may be satisfied when the expected value of the next lottery opportunity L is below a predetermined lower limit value. Specifically, for example, when the value is used as an expected value, the termination condition may be satisfied when the average value of a privilege that may be given at the next lottery opportunity is below the lower limit value. . Also, if there is only one privilege to be granted, the privilege functions as a specific privilege, and it is interpreted that the termination condition is satisfied when the winning probability becomes zero (less than the lower limit) with the grant of the privilege. Good. In this case, the grant of a specific privilege (one privilege) may also be included when it falls below the lower limit. Similarly, even when a plurality of benefits are prepared, it may be included when the expected value falls below the lower limit value with the grant of a specific privilege (for example, the highest value). That is, in these cases, a privilege that functions as a factor below the lower limit functions as a specific privilege, and the termination condition may be satisfied when the privilege is granted.

  In the above embodiment, a box-type image is used as the option image 51a. However, the present invention is not limited to such a form. Various images such as a circle may function as the option image 51a. Moreover, each lottery opportunity L is not limited to the form which is drawn through selection from choices, such as the choice image 51a. For example, each lottery opportunity may be configured to realize a lottery using a random number or the like. Moreover, the lottery process may or may not be displayed. Therefore, the display of options such as the option image 51a may be omitted. That is, the lottery for each lottery opportunity may be realized in various modes. Therefore, the increase in the expected value is not limited to the form in which the selected option is excluded from the next selection target. As long as the expected value of the next lottery opportunity L is higher than that of the previous lottery opportunity L, the expected value may be increased in an appropriate form. For this reason, the rate of increase of the expected value may also be set regardless of the number of selected options. For example, the rate of increase may increase or decrease as the number of times increases. Alternatively, the expected value may rise uniformly regardless of the number of times.

  Further, for example, when the lottery opportunity L satisfies the privilege condition, an additional privilege may be granted in addition to the privilege to be granted. For example, the privilege condition may be satisfied when the remaining number of options becomes a predetermined number (for example, two) or less, or when a lottery opportunity L of a predetermined number or more is continuously provided. Further, as an additional privilege, an increase in expected value may be additionally given in addition to a normal increase in expected value. Specifically, for example, when the number of remaining options is two, when the winning probability (expected value) is originally 50%, a further 50% winning probability is given as a bonus, and a winning probability of 100%, that is, The number of benefits may be increased so that any option is won. In addition, the privilege condition may include appropriate requirements depending on the play situation, the management situation such as the campaign, and the like. The same applies to additional benefits. That is, it is not limited to the above-described additional expected value (or increase in the number of benefits), and various benefits may be used as additional benefits.

  Moreover, the above-mentioned form demonstrates the example in which each unspecified user who utilizes game machine GM comprises the user group PG. However, the user group PG is not limited to such an example. For example, a specific user group such as a user of a specific gender, presence / absence of user authentication, or a specific user status specified by various conditions such as a user of a specific play situation such as a user who owns a specific special music It may function as the user group PG. That is, each lottery opportunity L may be provided for various specific user groups. Further, the user group PG is not limited to each user who uses the common game machine GM. For example, each user who uses a plurality of game machines GM may function as the user group PG. For example, the plurality of game machines GM may be specified in units of stores 4 or may be arranged across different stores 4. Further, for example, a related store such as a so-called chain, or each game machine GM in a specific area such as a neighborhood may function as such a plurality of game machines GM. Furthermore, such a plurality of game machines GM may be specified based on the manufacturer or the type of game provided. On the other hand, between such a plurality of game machines GM, the types of manufacturers and games may be the same or different. That is, a range of target game machines GM that provide each lottery opportunity L under various conditions may be set.

  In the above-described embodiment, an example in which information on expected values is notified through the standby screen 60 is described. However, the notification of expected value information is not limited to such an example. For example, the expected value information may be provided through various communication means such as an email, an application, or a WEB site. Also, the notification condition is not limited to the form based on the expected value. For example, the notification condition may be satisfied in a specific period resulting from a time zone, a season, a campaign, or the like.

When the termination condition is not satisfied in the opportunity providing means (30) for providing the lottery opportunities in order to each user (P) for PG) and one lottery opportunity (L1) among the lottery opportunities, Expected value changing means for changing the expected value of the next lottery opportunity (L2) following the one lottery opportunity so that the expected value indicating the degree of expectation regarding the grant of the privilege is increased compared to the one lottery opportunity. (30).

  According to the present invention, each lottery opportunity is provided for a plurality of users. The next lottery opportunity is set to have a higher expected value than the current lottery opportunity. As a result, competition among users can be promoted, and expectations for the next lottery opportunity can be increased. By these, utilization of an early lottery opportunity can be promoted.

  As one aspect of the game system of the present invention, an expected value acquisition means (30) for acquiring the expected value of the next lottery opportunity based on a change result of the expected value change means, and calculation of the expected value acquisition means An expected value notification means (30) for notifying each user of the expected value of the next lottery opportunity based on the result may be further provided. In this case, the expected value can be recognized by a user who may use the next lottery opportunity. As a result, the range of users competing for the use of the next lottery opportunity can be expanded. By these, utilization of an early lottery opportunity can be further promoted.

  The notification of the expected value may be executed as appropriate, for example, constantly or when a predetermined condition is satisfied. For example, in the aspect in which the expected value of the present invention is notified, the expected value notifying means performs notification of the expected value when the expected value of the next lottery opportunity is a predetermined value or more, while the expected value When the value is less than the predetermined value, the notification of the expected value may be omitted. In this case, notification of the expected value can be limited to a case where the expected value is equal to or greater than a predetermined value, so that the usefulness of the expected value information can be improved.

  The expected value may be raised in various ways. For example, the opportunity providing means uses a first element set (example of FIG. 6) including a plurality of lottery elements (51a) as a lottery object, and the selected lottery element selected by lottery from the first element set is the The first lottery opportunity is provided so that the privilege is given when associated with the privilege, and the expectation value changing means is a second element set excluding the selected lottery element from the first element set The expected value is changed by setting the second element set so that (example in FIG. 7) is used in the next lottery opportunity, and the end condition is that the expected value of the next lottery opportunity is It may be satisfied at least when it falls below a predetermined lower limit. Further, in this aspect, the privilege includes at least one specific privilege that functions as a factor that causes the expected value to exceed the predetermined lower limit value, and the opportunity providing means includes the selected lottery element as the specific privilege. The one lottery opportunity is provided so as to grant the specific privilege when associated, and the end condition is satisfied at least when the specific privilege is granted in the one lottery opportunity Also good.

  Further, in the aspect of the present invention in which the second element set is used in the next lottery opportunity, the opportunity providing means is configured to further grant an additional privilege when the second element set satisfies a privilege condition.

  Similarly, in the aspect of the present invention in which the second element set is used in the next lottery opportunity, the privilege includes a plurality of privileges, and the plurality of games of the game that can be owned by each user as the plurality of privileges. When each element is used and a corresponding lottery element corresponding to a game element owned by a user who is provided with the next lottery opportunity is included in the second element set, in the next lottery opportunity, the second element A third element set in which the corresponding lottery element is further excluded from the set may be used instead of the second element set. Alternatively, in one aspect of the game system of the present invention, the opportunity providing means is configured such that the privilege is owned by each user, and the user who is provided with the next lottery opportunity owns the privilege. If so, the content of the privilege of the next lottery opportunity may be changed. In these cases, since it is possible to suppress redundant possession of benefits, it is possible to improve the attractiveness of each lottery opportunity. As a result, the use of the next lottery opportunity can be further promoted.

  The game system of the present invention may provide various games. Moreover, in each lottery opportunity, various privilege may be provided according to various games. For example, in one aspect of the game system of the present invention, as the game, a music game that guides the execution time at which a play action should be performed in accordance with the rhythm of music is used. Special music limited in use may be used.

  In one aspect of the game system of the present invention, the expectation value changing means may function again as the first lottery opportunity when the end condition is satisfied in the one lottery opportunity. In addition, the expected value may be reset. In this case, it can suppress that an expected value continues rising.

  As the expected value, various values indicating the degree of expectation regarding the granting of a privilege may be used. For example, in one aspect of the game system of the present invention, as the expected value, at least one of a value indicating the winning probability of the privilege and a value indicating the value of the privilege may be used.

  On the other hand, the computer program of the present invention is configured to cause a computer to function as each means of the above-described game system. The server device of the present invention is connected to a display device that displays the game screen via a network and functions as each unit of the above-described game system.
