A control device 32 controls a progression degree X by specifying the plurality of sub-stages S in each stage T in order. In the current sub-stage Sm of the stage Tn specified by the progression degree X, the control device selects one item to be imparted to the player, by drawing, from among drawing objects including the items corresponding to the respective sub-stages S from the first sub-stage S1 to the current sub-stage Sm of the stage Tn.

Description

  The present invention relates to a technique for providing a game for collecting items.

  Conventionally, a game in which items are given to players by executing various events has been proposed. For example, in Non-Patent Document 1, the stage is advanced by achievement of an event such as a cave search or a battle with an enemy character, while the player selects an item by executing a lottery event in which one of a number of items is selected by a lottery process. A game that can be acquired has been proposed.

“Social Game General Information Magazine Application STYLE Vol.2”, East Press, Inc., April 1, 2011, p.26-p.29

  However, since the item given to the player is selected regardless of the stage being played in the lottery event of the technology of Non-Patent Document 1, the lottery event is an incentive for the player to advance the stage (game play by the player). It does not work as an incentive to promote In view of the above circumstances, an object of the present invention is to give an incentive to advance a stage to a player.

  Means employed by the present invention to solve the above problems will be described below. In order to facilitate understanding of the present invention, reference numerals in the drawings will be appended in parentheses for convenience in the following, but the present invention is not intended to be limited to the illustrated forms.

  The game apparatus (14A, 14B) of the present invention is a game apparatus (14A, 14B) that provides a player with a game that collects a plurality of items that are divided so as to correspond to each of a plurality of stages (T). The progress management unit (32, SD11 to SD15) that controls the progress (X) of the game that designates one of the stages (T), and the stage (T) that the progress (X) designates. A lottery processing unit (32, E1, E2) for selecting an item to be given to the player from a lottery target including a plurality of items; In the above configuration, since an item to be given to the player is selected from a lottery target including a plurality of items corresponding to the stage (T) specified by the progress (X), for example, the progress (X) of the game is Compared to a configuration in which items are selected regardless of the lottery process, it is possible to give the player an incentive to advance the stage (T) and promote the progress of the game.

  In a preferred aspect of the present invention, the plurality of items corresponding to each of the plurality of stages (T) are classified for each sub-stage (S) in the stage (T), and the progress management unit (32, SD11 to SD15). ) Controls the degree of progress (X) designating the sub-stage (S) in any one of the plurality of stages (T), and the lottery processing unit (32, E1, E2) is in one stage (T). When the degree of progress (X) designates the first substage (S), the item corresponding to the first substage (S) and the front of the first substage (S) among the one stage (T) From the lottery object including the items corresponding to the second substage (S) and including more items than the lottery object when the degree of progress (X) specifies the second substage (S). Select the item to grant. In the above aspect, the lottery object of the first substage (S) includes a larger number of items than the lottery object of the second substage (S) in front of the first substage (S). Assuming that the selection probabilities of the respective items are the same, the probability that an item corresponding to the first substage (S) can be acquired is lower than the probability that an item corresponding to the second substage (S) can be acquired. Therefore, in the second substage (S) in the stage (T), it is possible to promote the execution of an event (for example, a lottery process) for acquiring items as compared to the first substage (S). . For example, the lottery processing unit (32, E1, E2) selects the lottery object so that the total number of the lottery objects increases as the substage (S) specified by the degree of progress (X) is located rearward in the stage (T). In the managed configuration, the difficulty of acquiring an item increases as the game progresses in the stage (T), so the effect of promoting an event for acquiring the item is particularly remarkable.

  The configuration for increasing the total number of the lottery objects as the rear sub-stage (S) in the stage (T) is arbitrary. For example, the first sub-stage (S) in one stage (T) has a degree of progress. When (X) designates, a plurality of items corresponding to a plurality of substages (S) from the first substage (S1) to the first substage (S) in one stage (T) are subject to lottery The configuration included in is suitable. According to the above configuration, the total number of lottery objects can be reliably increased (monotonically increased) with a simple configuration.

  In a preferred aspect of the present invention, the lottery processing unit (32, E1, E2) has not yet issued a lottery object to the player by the first lottery process (E1) executed in exchange for the currency value owned by the player. The first lottery unit (32, E1) for selecting an item to be given to the player from the items to be given and the second lottery process (E2) executed under different conditions from the first lottery process (E1) And a second lottery section (32, E2) for selecting items to be given from the lottery targets. In the above aspect, the first lottery process (E1) executed in exchange for the currency value and the second lottery process (E2) executed under different conditions from the first lottery process (E1) can be executed. . Since the second lottery process (E2) is executed under conditions different from the consumption of the virtual currency, it is possible to promote participation in the game as compared with the configuration in which only the first lottery process (E1) is executed. is there. Further, in the configuration in which the difficulty level of item acquisition increases as the rear sub-stage (S) in the stage (T), the first lottery process (E1) in which an unassigned item is given to the player is executed. Is also promoted and effective monetization is realized.

  In a preferred aspect of the present invention, the progress management unit (32, SD11 to SD15) sets the progress (X) so as to shift to the stage (T) in front of the stage (T) specified by the progress (X). It can be changed. In the above aspect, there exists an advantage that it can re-challenge acquisition of an item by shifting to the stage (T) where the player played in the past.

  In a preferred aspect of the present invention, each of the plurality of items is represented by an image of one or more characters corresponding to the item, and is displayed together with a mark (R) corresponding to the character. In the above aspect, since the image representing each item includes the mark (R) corresponding to one or more characters corresponding to the item, the player who has viewed the item image visually recognizes the character corresponding to each item. There is an advantage that it can be grasped intuitively and intuitively. The positional relationship between the character image and the mark is arbitrary. For example, a configuration in which a mark is placed on a character image or a configuration in which a mark is placed near (around) a character image may be employed. The mark is a sign (a mark) that can be visually identified by the player. For example, a figure, a symbol, or a character is exemplified as a typical example of the mark.

  In the game device (14A, 14B) according to a preferred aspect of the present invention, the mark (R) of the character of the first item is set to the valid state in exchange for the first item and the second item given to the player. In addition, the item (R) of the character of the second item is set to an invalid state, the mark (R) of the character of the second item is set to an active state, and the mark (R) of the character of the first item is Both the item set in the disabled state, the item in which the marks (R) of both the first item character and the second item character are set in the enabled state, and both the first item character and the second item character The combination processing unit (32, E3) that selects and assigns to the player an item whose mark (R) is set to an invalid state Comprising the. In the above aspect, the item corresponding to the combination of the validity / invalidity of the mark (R) of the character of the first item and the validity / invalidity of the mark (R) of the character of the second item is the first item and the second item. Since it is given to the player in exchange, there is an advantage that the player can estimate the combination of the first item and the second item necessary for acquiring his / her desired item.

  The present invention is also specified as a program (PGM) for causing a computer to function as the game apparatus (14A, 14B) according to each of the above aspects. The program (PGM) of the present invention provides a computer with a plurality of stages (T) in order to provide a player with a game that collects a plurality of items divided to correspond to each of the plurality of stages (T). Select an item to be given to the player from a lottery target that includes a plurality of items corresponding to the stage (T) specified by the progress management process that controls the progress (X) of the game that specifies any one and the progress (X) The lottery process to be executed is executed. According to the above program (PGM), the same operation and effect as the game device (14A, 14B) of the present invention are realized. The program (PGM) of the present invention is provided in a form stored in a computer-readable recording medium and installed in the computer, or is provided in a form distributed via a communication network and installed in the computer.

<First Embodiment>
FIG. 1 is a block diagram of a game system 100 according to the first embodiment of the present invention. The game system 100 according to the first embodiment includes a terminal device 12 and a game device 14A that communicate with each other via a communication network 16 (for example, the Internet). The game device 14A provides a game to a player who owns the terminal device 12. Although only one terminal device 12 is shown in FIG. 1 for convenience, actually, a plurality of terminal devices 12 communicate with the game device 14A via the communication network 16.

  Each terminal device 12 is a communication terminal such as a mobile phone or a personal digital assistant (PDA), and includes a control device 22, a communication device 24, a display device 26, and an input device 28. The control device 22 comprehensively controls each element of the terminal device 12. The communication device 24 communicates with the game device 14A via the communication network 16. The communication between the terminal device 12 and the communication network 16 is typically wireless communication. However, in a configuration in which a stationary personal computer or the like is used as the terminal device 12, for example, the terminal device 12 and the communication network 16 are connected to each other. Wired communication.

  The display device 26 (for example, a liquid crystal display panel) displays various images under the control of the control device 22. For example, an image of a game provided by the game device 14A (hereinafter referred to as “game screen”) is displayed on the display device 26. The input device 28 is a device for the player to input an instruction to the terminal device 12, and includes, for example, a plurality of operators that the player operates. Note that a touch panel integrated with the display device 26 and a microphone for inputting an instruction to the terminal device 12 by voice may be employed as the input device 28.

  The game apparatus 14A is a web server that provides each player with a game for acquiring items by executing various events. The game of the first embodiment is a browser game whose theme is a video work such as a drama or a movie in which a plurality of performers (characters) appear (hereinafter referred to as “material work”). Proceed while acquiring items represented by drawn cards (trading cards and bromide cards).

  In the game according to the first embodiment, as shown in FIG. 2, N stages (T1 to TN) T (T1 to TN) corresponding to each story into which the material works are divided are prepared. The nth (n = 1 to N) stage Tn is divided into M substages S (S1 to SM) corresponding to the respective scenes constituting the nth episode of the material work. In the following description, the case where each stage T is configured by the same number (M) of substages S is illustrated for convenience, but the number M of substages S may be different for each stage T. is there.

  As shown in FIG. 1, the game device 14 </ b> A is realized by a computer system including a control device 32, a storage device 34, and a communication device 36. The control device 32 comprehensively controls each element of the game device 14A by executing the program PGM stored in the storage device 34. The communication device 36 communicates with each terminal device 12 via the communication network 16. The storage device 34 stores a program PGM executed by the control device 32 and various data used by the control device 32. A known recording medium such as a semiconductor recording medium or a magnetic recording medium or a combination of a plurality of types of recording media may be employed as the storage device 34. Further, for example, the storage device 34 (virtual one storage device) can be configured by a plurality of server devices installed at geographically different positions.

  The storage device 34 stores a plurality of items that can be given to the player. Specifically, a plurality of basic item data (master data) Q corresponding to different items is stored in the storage device 34. As shown in FIG. 1, each basic item data Q includes an identification code QID, attribute information Q1, attribute information Q2, and image data QG. In the first embodiment, a configuration in which the basic item data Q is stored in a single storage device 34 is exemplified, but each data can be distributed and held in a plurality of storage devices. For example, the image data QG of each item can be stored in a storage device separate from other data (QID, Q1, Q2).

  The plurality of items stored in the storage device 34 are classified into a plurality of classes C (C1 to C3). A plurality of items belong to each class C. The attribute information Q1 of the basic item data Q specifies the item class C. Each item of class C1 and class C2 is an item given to the player by a lottery process executed in the game. Class C2 is a set of items (rare items) that have a lower probability of being selected in the lottery process than class C1. Note that the class C2 may be divided into a plurality of classes having different selection probabilities in the lottery process.

  As shown in FIG. 2, the plurality of items of class C1 are divided into N groups corresponding to different stages T. A plurality of items belong to each group. The plurality of items in the group corresponding to each stage T is divided into M subgroups corresponding to different substages S in the stage T. A plurality (three in the example of FIG. 2) of items belong to each subgroup. The attribute information Q2 of the basic item data Q corresponding to each item of the class C1 specifies a stage T (group) and a substage S (subgroup) corresponding to the item. On the other hand, items of class C2 are classified for each stage T. Therefore, the attribute information Q2 of the item of class C2 specifies the stage T corresponding to the item. Since items of class C2 are not classified for each sub-stage S, a configuration in which designation of sub-stage S in attribute information Q2 is set to a predetermined fixed value, or designation of sub-stage S in attribute information Q2 for items of class C2 A configuration in which is omitted can be adopted. In the first embodiment, the case where the number (three) of items corresponding to each sub-stage S is made common is illustrated, but the number of items may be different for each sub-stage S. Also, a configuration in which items of class C2 are not classified for each stage T (a configuration in which any item of C2 can be acquired at any stage T) may be employed.

  Class C3 includes a plurality (N × M) of items corresponding to each sub-stage S of each stage T. Each item of class C3 (hereinafter sometimes referred to as “privilege item”) is an item that is given to the player as a privilege when a predetermined condition is satisfied in each sub-stage S. Specifically, when the player acquires (completes) all items (three in the example of FIG. 2) of the class C1 corresponding to the substage S of each stage T, the privilege item corresponding to that substage S Is given to the player. The attribute information Q2 of each privilege item belonging to the class C3 designates the stage T and the substage S corresponding to the privilege item.

  The image data QG of each item designates the image of that item. The image data QG of each item corresponding to the mth (m = 1 to M) substage Sm of the nth stage Tn in the class C1 or the class C3 is the nth of the material works constituting the nth episode. The image extracted from the mth scene (scene) is shown. For example, in the image data QG of each item, one or more performers appearing in each scene of the material work can be drawn.

  The storage device 34 stores player data P corresponding to the progress of the game for each player. As shown in FIG. 1, the player data P includes an identification code PID, owned item data P1, acquisition history data P2, owned currency data P3, progress X, and reach V. Although the first embodiment exemplifies a configuration in which each piece of player data P is stored in a single storage device 34, each piece of data can be distributed and held in a plurality of storage devices. For example, the possessed currency data P3 can be stored in a storage device separate from other data.

  The identification code PID is a code for identifying a player (for example, a player name or a unique character string). The owned item data P1 designates an identification code QID of an item acquired by the player in the past and still owned. The acquisition history data P2 indicates the acquisition history (acquired / not acquired) of each item by the player. For example, the acquisition history data P2 designates an identification code QID of an item acquired by the player in the past (regardless of whether or not it is currently owned). The content of the owned item data P1 is changed by the disappearance of the item owned by the player. However, since the acquisition history data P2 is an item acquisition history (acquired / unacquired), the item owned by the player has disappeared. Even if it does not change. The owned currency data P3 designates the quantity of virtual currency owned by the player. The virtual currency means a virtual currency value that can be used in the game. For example, the player can acquire virtual currency in exchange for real currency.

  The progress degree X is a variable that specifies the stage (the degree of progress of the game) in which the player is actually playing. The achievement level V is a variable that designates the last stage (reaching point) played by the player. Specifically, the progress degree X specifies the stage T and the substage S that the player is currently playing, and the achievement level V is the last (last) of the stage T and the substage S that the player has played in the past. 1) stage T and sub-stage S are designated. The control device 32 changes the progress degree X and the achievement degree V as the game progresses. In general, in each stage T, the game progresses in order from the first substage S1 to the last substage SM, and when the last substage SM of one stage Tn ends, the next stage Tn + 1 is reached. The degree of progress X and the degree of achievement V are controlled so as to shift to the first substage S1 (that is, the game progresses in the order of each scene of the material work). The stage T designated by the progress degree X can be shifted to the front (past) stage (details will be described later), but the achievement degree V designates the last stage T and the substage S reached by the player. Even if the stage T designated by the progress degree X moves forward, the achievement degree V does not change.

  The control device 32 executes predetermined processing according to a request transmitted from the terminal device 12 in response to an operation on the input device 28, and receives image data of a game screen (web page) indicating the processing result from the communication device 36. The game screen is displayed on the display device 26 by transmitting to the terminal device 12. For example, when the player gives an instruction to start the game to the input device 28, the control device 32 displays the game screen 51 of FIG. 3 on the display device 26 of the terminal device 12. On the game screen 51, a plurality of buttons B (B1 to B4) are arranged. Each button B is an image (command button) of an operator that can be selectively operated by the player. The control device 32 executes processing corresponding to the button B operated by the player among the plurality of buttons B1 to B4.

  The player can acquire items by executing the lottery process. The lottery process is classified into a first lottery process E1 and a second lottery process 2. The player can instruct the first lottery process E1 by operating the button B1, and can instruct the second lottery process E2 by operating the button B2. In the first lottery process E1, an item that has not been given to the player in the past is selected by lottery, and in the second lottery process E2, an item is selected by lottery regardless of whether the player has been granted or not granted. The first lottery process E1 is permitted in exchange for the consumption of the currency value owned by the player, and the second lottery process E2 is permitted under predetermined execution conditions. The execution condition is not required to execute the first lottery process E1, and the consumption of the currency value is not required to execute the second lottery process E2. In other words, it can be said that the execution condition is canceled in exchange for the consumption of the currency value. As understood from the above description, the conditions for permission to execute are different between the first lottery process E1 and the second lottery process E2.

  FIG. 4 is a flowchart of processing executed by the control device 32 when the player operates the button B2 (free lottery). When the processing of FIG. 4 is started, the control device 32 determines whether or not the execution condition is satisfied (SA11). The execution condition is a condition for limiting the execution frequency of the second lottery process E2.

  Specifically, a condition that the number of executions of the second lottery process E2 for each predetermined unit time (for example, 2 hours) is less than the allowable number is set as the execution condition. For example, the time of the second lottery process E2 executed immediately before by the player is set in the player data P, and the success or failure of the execution condition is determined by comparing the time of the second lottery process E2 immediately before with the current time. The execution condition of the second lottery process E2 is changed as appropriate. For example, the execution condition may be that the execution interval of the second lottery process E2 (elapsed time from the execution of the immediately preceding second lottery process E2) exceeds the allowable time. The configuration for limiting the execution frequency of the second lottery process E2 is arbitrary. For example, a flag for designating whether or not the second lottery process E2 is executed is set for each player, and when the player executes the second lottery process E2, the flag is set to a valid state (a numerical value indicating that the execution has been performed). For example, according to the configuration in which the flags of the respective players are initialized to the invalid state (numerical value indicating non-execution) when a predetermined time within one day arrives, the execution time of the second lottery process E2 is set for each player. There is no need to remember.

  When the execution condition is not satisfied (for example, when the number of executions within the unit time exceeds the allowable number of times or when the execution interval of the first lottery process E1 is less than the allowable time), the control device 32 cannot execute the second lottery process E2. This is notified to the player and the process is terminated. On the other hand, when the execution condition is satisfied (SA11: YES), the control device 32 executes the second lottery process E2 (SA12 to SA19). When the second lottery process E2 is started, the control device 32 selects either class C1 or class C2 by lottery (SA12). Specifically, the control device 32 generates a random number within a predetermined range, for example, and selects a class C corresponding to the random number. However, the selection probability of class C2 is lower than the selection probability of class C1. Then, the control device 32 determines whether or not the class C1 is selected in step SA12 (SA13).

  When class C1 is selected (SA13: YES), the control device 32 selects a lottery candidate (hereinafter referred to as “lottery object”) from a plurality of items of class C1 (SA14). In the first embodiment, a lottery object is selected according to the degree of progress X stored in the storage device 34. Specifically, among the M substages S1 to SM of the stage T designated by the progress degree X, the control device 32 selects items corresponding to the substages S before the current substage S designated by the progress degree X. Is selected as a lottery target.

  FIG. 5 is a schematic diagram showing the relationship between the degree of progress X and the lottery object. FIG. 5 illustrates the case where each stage T includes five substages S1 to S5 (M = 5). As shown in FIG. 5, for example, when the progress degree X designates the first sub-stage S1 in the n-th stage Tn (X = Tn, S1), the control device 32, among the plurality of items of class C1, An item corresponding to the sub-stage S1 of the stage Tn (that is, an item whose attribute information Q2 specifies the sub-stage S1 of the stage Tn) is selected as a lottery target.

  When the progress degree X designates the second and subsequent substages Sm of the stage Tn, the control device 32, as shown in FIG. 5, the first substage in the stage Tn among the plurality of items of class C1. The item corresponding to each substage S from S1 to the current substage Sm is selected as a lottery target. For example, when the progress degree X designates the second substage S2 of the stage Tn (X = Tn, S2), the items corresponding to the substage S1 and the substage S2 in the stage Tn are selected as the lottery targets. When the progress degree X designates the third substage S3 of the stage Tn (X = Tn, S3), it corresponds to each substage S from the substage S1 to the substage S3 in the stage Tn. An item is selected as a lottery target. When the progress level X designates the last substage SM in the stage Tn (X = Tn, S5), items corresponding to all (M) substages S1 to SM in the stage Tn are selected. Selected as a target. Similarly, in the stage Tn + 1 immediately after the stage Tn, the item corresponding to each substage S before the current substage Sm in the stage Tn + 1 is selected as a lottery target.

  As can be understood from the above explanation, the item to be selected for the lottery is changed for each stage T designated by the progress degree X, and the current substage S designated by the progress degree X is moved backward in one stage T. The number of items to be selected increases as the position increases.

  The control device 32 selects one item to be given to the player from the lottery objects selected in step SA14 by lottery (SA15). Specifically, for example, the control device 32 generates a random number within a predetermined range and selects one item corresponding to the random number from the lottery targets. Since the selection probabilities of the respective items to be selected are the same, the probability that the item corresponding to the substage S is selected as the substage S specified by the degree of progress X is located rearward in one stage T. Will decline.

  On the other hand, when class C2 is selected in step SA12 (SA13: NO), the control device 32 selects a lottery object from a plurality of items of class C2 (SA16). Specifically, the control device 32 selects a plurality of items corresponding to the stage T specified by the degree of progress X stored in the storage device 34 of the class C2 as a lottery target. Then, the control device 32 selects, by lottery, one item to be given to the player from the lottery targets selected in step SA16 (SA17).

  The control device 32 gives the item selected in step SA15 or step SA17 to the player (SA18). Specifically, the identification code QID of the item selected by the control device 32 is added to the possessed item data P1 and the acquisition history data P2 of the player data P. When an item acquired by the player is selected, the identification code QID is added to the owned item data P1, but the acquisition history data P2 is not changed. And the control apparatus 32 displays the image of an item on the display apparatus 26 by transmitting the image data QG of the basic item data Q of the item provided to a player to the terminal device 12 (SA19). As can be understood from the above description, the control device 32 selects an item (the second lottery) from the lottery object by the second lottery process E2 that is executed under the predetermined execution condition without consumption of the virtual currency. Part).

  FIG. 6 is a flowchart of processing executed by the control device 32 when the player operates the button B1 (paid lottery) on the game screen 51 of FIG. When the process of FIG. 6 is started, the control device 32 executes an accounting process (SB11). The billing process is a process of subtracting a predetermined amount necessary for executing the first lottery process E1 from the virtual currency designated by the player's possessed currency data P3 (that is, a process of paying the virtual currency).

  When the billing process is executed, the control device 32 executes the first lottery process E1 (SB12 to SB19). First, similarly to steps SA12 and SA13, the control device 32 selects either class C1 or class C2 by lottery (SB12), and determines whether or not class C1 is selected (SB13).

  When the class C1 is selected (SB13: YES), the control device 32 selects a lottery object corresponding to the progress degree X from the plurality of items of the class C1 stored in the storage device 34 (SB14). Specifically, among the M sub-stages S1 to SM in the stage T designated by the progress degree X, each sub-stage S before the current sub-stage Sm designated by the progress degree X corresponds to the player. On the other hand, the control device 32 selects an item that has not been given in the past (that is, an item for which the identification code QID is not registered in the acquisition history data P2) as a lottery target. That is, in the second lottery process E2, the lottery target is selected regardless of the acquisition status of the past items, whereas in the first lottery process E1, items that the player has not acquired in the past are limited. Selected as a lottery target.

  For example, when the progress degree X designates the first substage S1 of the stage Tn, the control device 32 registers the identification code QID in the acquisition history data P2 among a plurality of items of the class C1 corresponding to the substage S1 of the stage Tn. One or more items that have not been selected are selected as lottery targets. When the progress level X designates the second and subsequent substages Sm of the stage Tn, the control device 32 corresponds to each substage S from the first substage S1 of the stage Tn to the current substage Sm. Among the plurality of items of class C1, one or more items that are not registered in the acquisition history data P2 are selected as objects for lottery. Accordingly, as in the second lottery process E2, the item to be selected for each stage T designated by the progress degree X is changed, and the sub-stage S designated by the progress degree X is positioned backward in one stage T. The number of items for lottery increases as the number increases.

  Similarly to step SA15 of the second lottery process E2, the control device 32 selects one item by lottery from the lottery objects selected in step SB14 (SB15). On the other hand, when class C2 is selected in step SB12 (SB13: NO), control device 32 selects a lottery object from a plurality of items of class C2 (SB16). Specifically, the control device 32 selects one or more items not assigned to the player among the items of the class C2 corresponding to the stage T specified by the degree of progress X as a lottery target. And the control apparatus 32 selects one item given to a player from the lottery object selected by step SB16 by lottery (SB17). Then, similarly to Step SA18 and Step SA19 of the second lottery process E2, the control device 32 gives the item selected in Step SB15 or Step SB17 to the player (SB18), and displays an image of the item on the display device 26. (SB19). As can be understood from the above description, the control device 32 selects an item that has not been granted to the player from the lottery object by the first lottery process E1 executed in exchange for the virtual currency owned by the player ( 1st lottery section). Note that if there is no unassigned item for each substage S up to the current substage Sm among the stages T specified by the progress degree X (completed), for example, the operation of the button B1 is invalidated. It is also possible to execute a lottery process similar to the second lottery process E2 after confirmation by the player.

  The control device 32 executes the process of FIG. 7 after the first lottery process E1 or the second lottery process E2. When the processing of FIG. 7 is started, the control device 32 refers to the acquisition history data P2 to determine whether or not all (three) items of the current substage S specified by the progress degree X have been acquired. Is determined (SC11). When all items of the current substage S have been acquired (SC11: YES), the control device 32 grants a privilege item of class C3 corresponding to the substage S to the player (SC12). That is, the privilege item identification code QID is added to the possessed item data P1 and the acquisition history data P2 of the player. On the other hand, when all the items of the sub-stage S have not been acquired (SC11: NO), the provision of the privilege item is not executed. In addition, when a player acquires all the items corresponding to each stage T, the structure which provides the player with the privilege item prepared for every stage T separately from the privilege item of each substage S is also suitable.

  Further, the control device 32 executes a progress management process (SD11 to SD15) for controlling the progress degree X and the achievement degree V. First, the control device 32 determines whether or not a first condition for advancing the game from the current substage Sm to the next substage S is satisfied (SD11). In the first embodiment, the condition that the number of lottery processes (first lottery process E1 or second lottery process E2) executed in the current substage S reaches a predetermined threshold is set as the first condition. When the first condition is not satisfied (SD11: NO), the control device 32 ends the progress management process without changing the progress degree X and the achievement degree V. It is also possible to individually set a threshold value (threshold value for the number of lottery processes) applied to the determination of success or failure of the first condition (for example, different for each substage S). For example, the number of items to be drawn increases as the current sub-stage S is positioned backward in one stage T (that is, the probability that an item corresponding to the current sub-stage S is selected decreases). In consideration of the above, a configuration in which the threshold value is set to a larger numerical value in the rear substage S in the stage T is preferable.

  On the other hand, when the first condition is satisfied (SD11: YES), the control device 32 determines whether or not the current substage Sm is the last substage SM in the stage T (SD12). When the current substage Sm does not correspond to the last substage SM (SD12: NO), the control device 32 changes the substage S designated by the progress degree X and the achievement degree V from the current substage Sm to the same stage T. To the next sub-stage Sm + 1 (SD13). That is, the control device 32 advances the game from the substage Sm to the next substage Sm + 1 in the current stage T, triggered by the establishment of the first condition.

  On the other hand, if the current sub-stage Sm corresponds to the last sub-stage SM in the stage T (SD12: YES), the control device 32 is used to advance the game from the current stage Tn to the next stage Tn + 1. It is determined whether or not the second condition is satisfied (SD14). In the first embodiment, the condition that the player correctly answers the quiz related to the material work (or the correct answer rate for a plurality of quizzes exceeds the threshold) is set as the second condition. That is, the control device 32 displays the quiz related to the material work or the performer on the display device 26 of the terminal device 12 and then receives an answer from the player. If the answer is correct, the second condition is established. On the other hand, if the answer is incorrect, it is determined that the second condition is not satisfied. A configuration in which the player can participate in the quiz on condition that a predetermined number (for example, (M−2)) of privilege items among the M privilege items corresponding to each sub-stage S of one stage T has been acquired. Is also suitable.

  When the second condition is satisfied (SD14: YES), the control device 32 changes the stage T designated by the progress degree X and the achievement degree V from the current stage Tn to the next stage Tn + 1, and the progress degree. The substage S designated by X and the achievement degree V is changed from the current substage SM to the first substage S1 in the stage Tn + 1 (SD15). That is, the control device 32 advances the game from the last substage SM in the current stage Tn to the first substage S1 in the next stage Tn + 1, when the second condition is satisfied. On the other hand, when the second condition is not satisfied (SD14: NO), the control device 32 ends the process of FIG. 7 without changing the progress degree X and the achievement degree V.

  As can be understood from the above description, the control device 32 executes the progress management process (SD11 to SD15), thereby realizing an element (progress management unit) that controls the progress X of the game. As described above, the control device 32 of the first embodiment advances the game to the stage T and the substage S in the rear of the material work, and proceeds to move to the stage T in front of the current stage T. It is possible to change the degree X. Specifically, when the player gives a predetermined operation to the input device 28, the control device 32 changes the stage T designated by the progress degree X to the stage Tn-1 immediately before the current stage Tn, and the progress degree. The substage S designated by X is changed from the current substage Sm to the last substage SM of the stage Tn-1 after the transition. That is, the player can return to the stage T played in the past and acquire an unacquired item. When the player gives a predetermined operation to the input device 28, the stage T and the substage S designated by the progress degree X are changed to the stage T and the substage S designated by the achievement degree V. That is, the player can advance the game to the last substage S that has reached the past.

  When the player operates the button B3 (composite) on the game screen 51 of FIG. 3, the control device 32 displays a plurality of items specified by the owned item data P1 (that is, items that the player has acquired in the past and still owns). ) Is executed in exchange for other items to the player. FIG. 8 is a flowchart of the composition process E3.

  The player who operates the button B3 can arbitrarily select two items to be processed (hereinafter referred to as “target item”) from a plurality of items owned by the player by appropriately operating the input device 28. It is. The control device 32 accepts selection of two target items (SE11). And the control apparatus 32 selects one item by lottery for the item of the class C1 corresponding to the stage T and the substage S which the progress degree X designates (SE12). The control device 32 gives the item selected in step SE12 to the player (SE13), and displays an image of the item on the display device 26 (SE14). Further, the control device 32 invalidates two target items among a plurality of items specified by the owned item data P1 (SE15). For example, a method of deleting the identification code QID from the owned item data P1 or a method of setting a flag set for each item of the owned item data P1 to an invalid state is employed for invalidating the item. As described above, the player can acquire items not only in the first lottery process E1 and the second lottery process E2, but also in the synthesis process E3.

  When the player operates the button B4 (picture book) on the game screen 51 of FIG. 3, the control device 32 displays an acquired item screen 52 on the terminal device 12 for the player to confirm items acquired in each substage S. It is displayed on the device 26. For example, the acquisition item screen 52 of the substage S designated by the progress degree X and the acquisition item screen 52 of the substage S arbitrarily designated by the player are displayed.

  The acquired item screen 52 is an image that displays the acquisition status of each item (class C1 or class C3) corresponding to one substage. That is, the image G designated by the image data QG is displayed for the acquired item, and the image g indicating unacquired for the unacquired item (for example, an image of a question mark “?” Meaning that the item is unknown). Is displayed. The control device 32 determines acquisition / non-acquisition for each item of one sub-stage S by referring to the acquisition history data P2, and for the acquired item, the image G of the image data QG of the basic item data Q And an acquired item screen 52 in which an image g is arranged for an unacquired item is generated. It is also possible to display on the display device 26 a game screen indicating the acquisition status of each item of class C2.

  As described above, in the first embodiment, an item selected by lottery from a lottery target including an item corresponding to the stage T (substage S) designated by the progress degree X is given to the player. That is, the items given to the player in the lottery process (first lottery process E1, second lottery process E2) are different for each stage T. Therefore, when compared with a configuration in which an item unrelated to the current stage T is selected by the lottery process, it is possible to give the player an incentive to advance the stage T and promote the progress of the game.

  In the first embodiment, the number of items to be selected increases as the sub-stage S designated by the degree of progress X is located rearward in one stage T. That is, as the game progresses in one stage T, the selection probability of the item corresponding to the current sub-stage S decreases, making acquisition difficult. Therefore, in comparison with a configuration in which items can be easily acquired in each sub-stage S in the stage T (for example, in a single sub-stage S, only an item corresponding to the sub-stage S is selected as a lottery target) It is possible to promote the execution of the first lottery process E1 and the second lottery process E2. In the first embodiment, in particular, by executing the first lottery process E1 permitted in exchange for the virtual currency, an unassigned item is given to the player, so that the execution of the first lottery process E1 is promoted. There is also an advantage that effective monetization is realized. On the other hand, since the second lottery process E2 is executed without consumption of virtual currency, the participation of a large number of players is promoted as compared with the configuration in which only the first lottery process E1 that requires consumption of virtual currency is executed. Is possible.

  As described above, in one stage T, the acquisition of items becomes more difficult in the rear sub-stage S. On the other hand, when the stage shifts to a new stage T, the process shifts to the first sub-stage S1 and the lottery target decreases. . That is, the difficulty level of item acquisition decreases each time a new stage T is entered. In a configuration in which the difficulty level of item acquisition monotonously increases over a plurality of stages T, there is a possibility that the player gets stuck in the middle of the game and the player stops the game. In the first embodiment, each time the stage T moves, the difficulty of acquiring an item decreases, so that it is difficult for the player to quit the game (it is possible for the player to continue the game). is there.

Second Embodiment
A second embodiment of the present invention will be described below. In addition, about the element which an effect | action and a function are equivalent to 1st Embodiment in each form illustrated below, each reference detailed in the above description is diverted and each detailed description is abbreviate | omitted suitably.

  In the first embodiment, the transition condition (first condition) of the substage S is that the number of lottery processes reaches a threshold value. In the second embodiment, the ratio of items acquired by the player among the plurality of items corresponding to the current substage S designated by the progress degree X (hereinafter referred to as “acquisition rate”) reaches a predetermined threshold. Adopted as the first condition for moving to the next sub-stage S. That is, in step SD11 of FIG. 7, the control device 32 calculates the item acquisition rate of the current substage S by referring to the acquisition history data P2, and the first condition is satisfied when the acquisition rate exceeds the threshold value. On the other hand, if the acquisition rate is lower than the threshold, it is determined that the first condition is not satisfied. For example, the acquisition of all items in the current substage S is preferable as the first condition (acquisition rate reaches 100%).

  In the first embodiment, the stage T transition condition (second condition) is that the player correctly answers the quiz related to the material work. In the second embodiment, the fact that the acquisition rate of items corresponding to the current stage T designated by the progress degree X reaches a predetermined threshold is set as a second condition for shifting to the next stage T. That is, in step SD14 of FIG. 7, the control device 32 calculates the acquisition rate of the item corresponding to the current stage T by referring to the acquisition history data P2, and the second condition is satisfied when the acquisition rate exceeds the threshold value. It is determined that it has been established.

  In the second embodiment, the same effect as in the first embodiment is realized. In the second embodiment, if the item acquisition rate of each sub-stage S does not reach the threshold value, the process cannot proceed to the next sub-stage S. If the item acquisition rate of each stage T does not reach the threshold value, the next stage Cannot move to T. Therefore, compared with the first embodiment, there is an advantage that the execution of the first lottery process E1 and the second lottery process E2 is promoted. The effect of promoting the first lottery process E1 that can acquire an item that has not been granted to the player is particularly remarkable.

<Third Embodiment>
A third embodiment of the present invention will be described. FIG. 9 is a schematic diagram of the basic item data Q in the third embodiment. As shown in FIG. 9, the basic item data Q of the third embodiment has a configuration in which attribute information Q3 is added to the same elements (QID, Q1, Q2, QG) as in the first embodiment. The attribute information Q3 designates one or more performers (characters) included in the image G drawn by the image data QG. Further, the image G designated by the image data QG of the item corresponding to the mth sub-stage Sm in the nth stage Tn is the mth of the nth episodes of the material work as shown in FIG. A plurality of (K) marks R (R1 to RK) are added to visually represent performers appearing in the scene. It is also possible to place a mark R in the vicinity (periphery) of a card-type image in which each scene of the material work is drawn.

  Each mark R added to the image G of the item is set to either a valid state or an invalid state. The mark R in the valid state and the mark R in the invalid state can be visually distinguished by being displayed in different modes. For example, the valid state mark R is expressed in a state where the inside of the circular frame image is filled, and the invalid state mark R is expressed in a state where the inside of the frame image is not filled (transparent state). The display mode (for example, the fill color) of the mark R set to the valid state is different for each mark R.

  Each mark R of the image G indicated by the image data QG corresponds to each performer appearing in the material work. Of the K marks R, the mark R corresponding to the performer drawn on the image G is set to the valid state, and the remaining marks R are set to the invalid state. For example, as shown in FIG. 9, in the image G in which the performer Y1 is drawn, the first mark R1 corresponding to the performer Y1 among the K marks R1 to RK is set to the valid state and the remaining characters are displayed. The marks R2 to RK are set to an invalid state. For example, in the image G in which the performers Y1 and Y2 are drawn, the mark R1 corresponding to the performer Y1 and the mark R2 corresponding to the performer Y2 among the K marks R1 to RK are set to the valid state. In addition, the remaining mark R is set to an invalid state. In an image G of a landscape or the like in which no performer corresponding to each mark R appears (for example, an image in which no performer exists or an image in which only performers other than the performer corresponding to the mark R appear) is K pieces. The marks R1 to RK are set to an invalid state.

  The image data QG described above is displayed on the display device 26 as a result of the first lottery process E1, the second lottery process E2, and the composition process E3, as in the first embodiment (SA19, SB19, SE15). The acquired item screen 52 is displayed on the display device 26 when the player operates the button B4. When the image G indicated by the image data QG is not sufficiently clear, when the performer's face is hidden, or when the image G indicated by the image data QG is reduced and displayed on the small display device 26, each Only from the image G of the item, there is a possibility that the player cannot clearly recognize the performer drawn in the image G. In 3rd Embodiment, since the mark R corresponding to the performer drawn on the image G of each item is set to a valid state and displayed on the display device 26, the performer drawn on the image G of each item is displayed. There is an advantage that the player can grasp visually and intuitively.

  In step SE12 of the synthesis process E3 (FIG. 8) of the third embodiment, one item is given to the player by lottery from the lottery targets corresponding to the two target items selected by the player in step SE11. As shown in FIG. 10, the specific contents of step SE12 will be described below assuming that the player selects the target item A1 corresponding to the performer Y1 and the target item A2 corresponding to the performer Y2. As shown in FIG. 10, in the image G of the target item A1, the mark R1 corresponding to the performer Y1 is set to the valid state, and in the image G of the target item A2, the mark R2 corresponding to the performer Y2 is set to the valid state. The

  Of the plurality of items of class C1 corresponding to the stage T and substage S specified by the progress degree X, the control device 32 determines whether the mark R1 of the performer Y1 of the target item A1 is valid / invalid and the target item A2. The following four items (part (a) to part (d) in FIG. 10) corresponding to the combination of the valid / invalid state of the mark R2 of the performer Y2 are set as the lottery targets. The marks R other than the marks R1 and R2 are in an invalid state.

[A] An item in which the mark R1 of the performer Y1 of the target item A1 is set to the valid state and the mark R2 of the performer Y2 of the target item A2 is set to the invalid state (part (a) in FIG. 10)
[B] An item in which the mark R2 of the performer Y2 of the target item A2 is set to the valid state and the mark R1 of the performer Y1 of the target item A1 is set to the invalid state (part (b) of FIG. 10).
[C] An item in which both the mark R1 of the performer Y1 of the target item A1 and the mark R2 of the performer Y2 of the target item A2 are set in the valid state (part (c) in FIG. 10).
[D] An item in which both the mark R1 of the performer Y1 of the target item A1 and the mark R2 of the performer Y2 of the target item A2 are set in an invalid state (part (d) in FIG. 10).

  In step SE12, the control device 32 determines the attribute of the basic item data Q of each item from a plurality of items of class C1 corresponding to each substage S before the current substage Sm among the stages T specified by the progress degree X. By referring to the information Q3, a lottery object including the items [a] to [d] is selected. The item [a] is an item in which the attribute information Q3 specifies the performer Y1, the item [b] is an item in which the attribute information Q3 specifies the performer Y2, and the item [c] is an attribute The information Q3 is an item that designates both the performer Y1 and the performer Y2, and the item [d] is an item that the attribute information Q3 designates neither the performer Y1 nor the performer Y2. For example, when both the target item A1 and the target item A2 correspond to the performer Y1, the item [a] in which the mark R1 corresponding to the performer Y1 is set to the valid state and the mark R1 are set to the invalid state. The item [d] is selected as a lottery target. The control device 32 selects one item to be given to the player by lottery from the lottery targets set under the above conditions. The processing after step SE13 is the same as that in the first embodiment.

  When the player Z1 gives a predetermined operation to the input device 28, the control device 32 displays the acquisition item screen 52 corresponding to the acquisition history data P2 of the other player Z2 designated by the player Z1 on the terminal device 12 of the player Z1. It is displayed on the display device 26. However, among the items already acquired by the player Z2, only the items corresponding to the sub-stages S before the current sub-stage S specified by the achievement level V of the player Z1 are displayed on the display device 26 (that is, the player Z1 is still A configuration in which the item of the sub-stage S that has not reached is not shown to the player Z1) is preferable.

  By visually recognizing the acquired item screen 52 of the player Z2, the player Z1 can confirm the mark R added to the image G of the item that has not yet been acquired (item acquired by the player Z2). is there. Therefore, the player Z1 can estimate a combination of target items as materials for synthesizing his unacquired items. For example, when the mark R1 and the mark R2 are set in the valid state for the item Ax not acquired by the player Z1 in the acquired item screen 52 of the player Z2, the player Z1 is the item in which the mark R1 is set in the valid state. It can be estimated that there is a high possibility that the desired item Ax can be acquired by selecting the item for which the mark R2 is set to the valid state as the target item for the synthesis process E3. However, as can be understood from the above description, an item other than the desired item Ax may be selected.

  In 3rd Embodiment, the mark R which shows the performer of drawing object is added to the image G of image data QG, and the item corresponding to each combination of the valid state / invalid state of each mark R of an object item is made into a lottery object. In the synthesis process E3, an item to be given to the player is selected. Therefore, there is an advantage that the player can estimate a combination of target items necessary for acquiring his / her desired item.

<Fourth embodiment>
FIG. 11 is a block diagram of a game apparatus 14B according to the fourth embodiment. The game device 14B is an electronic device that causes a player (owner) to play a game similar to the first embodiment. For example, a portable device such as a mobile phone or a portable information terminal is suitable as the game apparatus 14B. As shown in FIG. 11, the game apparatus 14 </ b> B includes a control device 32, a storage device 34, a display device 26, and an input device 28.

  The storage device 34 stores a program PGM, player data P, and a plurality of basic item data Q, as in the first embodiment. The control device 32 operates in the same manner as in the first embodiment by executing the program PGM. As understood from the above description, the game device 14B of the fourth embodiment functions as a device that provides the player with the game provided by the game device 14A of the first embodiment alone. Therefore, the same effect as that of the first embodiment is realized in the fourth embodiment.

<Modification>
Each of the above-described embodiments can be variously modified. Specific modifications are exemplified below. Two or more aspects arbitrarily selected from the following examples can be appropriately combined as long as they do not contradict each other.

(1) In the first lottery process E1 and the second lottery process E2 in the above-described embodiments, as described with reference to FIG. 5, each sub-stage from the first sub-stage S1 to the current sub-stage Sm in the stage Tn. Although the item corresponding to the stage S is selected as a lottery target, the method of controlling the number of items to be selected for each substage S is appropriately changed.

  For example, as shown in FIG. 12, in each sub-stage S after a specific sub-stage S in the stage Tn, it is also possible to exclude items of a predetermined number of sub-stages S from the top in the stage Tn. . In FIG. 12, the case where the item of substage S1 is excluded from the lottery object of substage S4 and substage S5 in stage Tn is illustrated. Further, as shown in FIG. 13, a configuration in which the number of items to be selected (the number of substages S corresponding to the items to be selected) does not change over a plurality of substages S is also employed. FIG. 13 illustrates a case where, in each substage Sm after the substage S3, items corresponding to the three substages S before the current substage Sm are selected as objects for lottery. Further, in a specific substage S in the stage Tn, it is possible to reduce the number of items to be selected as compared with the preceding and succeeding substages S. That is, the configuration in which the number of items to be selected in each sub-stage S monotonously increases in the stage T is not essential in the present invention.

  As can be understood from the above examples, the lottery object in the substage SA in the stage Tn designated by the progress degree X is the item corresponding to the substage SA and the position in front of the substage SA in the stage Tn. And an item corresponding to the sub-stage SB, and the degree of progress X is selected so as to include a larger number of items than the lottery target when the sub-stage SB is designated.

(2) In each of the above-described embodiments, only the item of class C1 is selected as the lottery object in step SB14 of the first lottery process E1 and step SA14 of the second lottery process E2. However, the lottery object is an item other than class C1. Including configurations are also employed. For example, it is also possible to include items common to a plurality of stages T and a plurality of substages S (items not classified into the stage T and the substage S) together with items of the class C1 in the lottery object.

(3) In the third embodiment, the acquisition item screen 52 of the player Z2 is displayed on the display device 26 of the terminal device 12 of the player Z1, but when the player Z1 confirms the acquisition item screen 52 of the player Z2, the player It is also possible to place an image G of an item acquired by the player Z2 among items not acquired by Z1 on the acquired item screen 52 of the player Z1 and display it on the terminal device 12 of the player Z1. For example, as shown in FIG. 14, an image G to which an image (character “watched” in the illustration of FIG. 14) indicating that it has been confirmed on the other person's acquired item screen 52 is added is the acquired item screen 52 of the player Z1. Are arranged at positions corresponding to the image G. According to the above configuration, once the acquired item screen 52 of the player Z2 is confirmed, the material for synthesizing the unacquired items can be obtained by confirming the acquired item screen 52 of the player Z1 thereafter. There is an advantage that a combination of target items can be estimated.

(4) In each of the above-described embodiments, the configuration in which the item of class C2 can be given to the player in the first lottery process E1 and the second lottery process E2 is exemplified. It is also possible to execute “the third lottery process” separately from the first lottery process E1 and the second lottery process E2. That is, the first lottery process E1, the second lottery process E2, and the third lottery process are selectively executed according to an instruction from the player, for example. In the first lottery process E1 and the second lottery process E2, only the class C1 item is selected as a lottery object, and the third lottery process that targets the class C2 item (rare item) as the lottery object is, for example, the first lottery process E1. It is executed in exchange for consumption of virtual currency in the same way as.

(5) In the above-described embodiments, the execution frequency condition (time restriction) is exemplified as the execution condition of the second lottery process E2, but the execution condition of the second lottery process E2 is changed as appropriate. That is, it is possible to permit the second lottery process E2 together with the above-described execution frequency condition or when another execution condition is satisfied instead of this condition. For example, in a configuration in which points are accumulated by achievement of various events in the game, a configuration that permits the execution of the second lottery process E2 in exchange for a predetermined amount of points (a configuration that includes consumption of points as an execution condition) is also employed. obtain.

(6) In the third embodiment described above, the state in which the inside of the circular frame image is filled is exemplified as the valid state of the mark R, and the state in which the inside of the frame image is not filled is exemplified as the invalid state of the mark R. The valid / invalid state of the mark R is not limited to the above examples. For example, it is possible to display the mark R in the valid state and hide the mark R in the invalid state.
