The processing of each floor includes a battle between a player character and an enemy character, granting a privilege such as a specific game medium to the player, a so-called RAID battle in which a plurality of players participate, encounters with other players, and / or This includes battles (matches) with other players. The player character is a game medium possessed by the player, and the enemy character is a game medium possessed by a non-player character or another player.

  A game medium is electronic data used in a game, and includes, for example, a card, an item, a character, an avatar, and the like. The game medium is electronic data that can be acquired, held, used, managed, exchanged, combined, strengthened, sold, discarded, and / or gifted, etc. by the player as the game progresses. The usage mode of the game media is not limited to those specified in this specification. A player can grow a character or acquire an item by executing a quest.

  In this embodiment, a card registered in advance in the game system will be described as an example of a game medium. The player character or enemy character card used in the battle has a battle parameter. The battle parameters include, for example, attack power, defense power, physical strength (or HP (hit points)), attributes (eg, fire, water, thunder, etc.), rarity (eg, normal, rare, S (super) rare, SS (double super) rare, SSS (triple super) rare, legend, etc.), skill (special effect) activation rate, attack speed (number of attacks in one turn, number of turns until attack, etc.), number of defenses in one match Parameters and / or jobs (eg, occupation, military type, etc.). The card to which one character is assigned is not limited to one card, and a plurality of cards having different battle parameters may be assigned to each character.

  As a lottery game, the server executes a lottery for selecting a character card from among a plurality of character cards set as a lottery object in accordance with a request from a player who operates the mobile terminal, and associates the selected character card with the player Are stored and given to the player. Character cards set as lottery targets are classified into a plurality of groups. Each group is classified according to the rarity of the character card. Each group may be classified according to the character attributes, the time or event when the character card is issued, the item worn by the character, or the like. The request from the player is a lottery request related to an instruction to execute a lottery on the server. When the server receives the lottery request from the player, the server randomly selects a character card from the character cards to be drawn with equal probability.

  Further, the server extracts a character card belonging to the same group as the group to which the selected character card belongs from the lottery target character cards, and deletes the extracted character card. That is, in the next lottery, the server selects a character card from among lottery targets that do not include a character card of the same group as the group to which the assigned character card belongs.

  FIG. 7B shows a card table for managing character cards. In the card table, for each character card, the card ID, name, image data file name, character name, rarity, HP, attack power, defense power, attributes, and the like of the character card are stored in association with each other.

  FIG.7 (c) shows the lottery object group table which manages the group to which the character card classified in a lottery game belongs. In the lottery object group table, for each character card to be a lottery object, a card ID of the character card, a group ID indicating a group to which the character card belongs, and the like are stored in association with each other. Each group is set for each of a plurality of classifications.

  Each group in one classification may be set according to different types of regulations. For example, in the first classification, the first group is a group with normal rarity, the second group is a fire group attribute, and the third group is a character card group issued this month. It may be classified as follows. Moreover, each classification may be set according to the same type of rules. For example, a group may be set for both the first classification and the second classification depending on the rarity. In addition, the same character card may be included in two or more different groups in one classification.

  In addition, the lottery target group defined by each classification may include a plurality of groups of the same type. For example, in the first classification, two groups A whose normality is normal may be included.

2.2.1. Configuration of Server Processing Unit 33 The server processing unit 33 includes a classification unit 331, a progress control unit 332, a display data output unit 333, a main game execution unit 334, a selection unit 335, an association unit 336, and a determination unit 337. Each of these units is a functional module realized by a program executed by a processor included in the server processing unit 33. Alternatively, each of these units may be mounted on the server 3 as firmware.

  The classification unit 331 classifies the character cards included in the lottery object into a plurality of groups before the lottery game is executed. The classification unit 331 classifies each character card to be a lottery into a plurality of groups for each of a plurality of classifications, sets group IDs, and stores them in a lottery card table.

  The classification unit 331 classifies each character card into a plurality of groups according to the value (for example, the degree of rarity) of each character card, and determines the number of character cards belonging to each group according to the value corresponding to each group. It may be changed. In that case, the classification unit 331 reduces the number of character cards belonging to the group as the value of the character card is higher, and increases the number of character cards belonging to the group as the group is lower in value of the character card. As a result, when low-value cards are selected by lottery, low-value cards are deleted together, so that it is possible to improve the probability that the player can acquire a high-value card in the next lottery.

  Further, the classification unit 331 sets an initial value of a lottery target group that is a target of the lottery process. The classification unit 331 stores all group IDs defined in each classification as an initial value of the lottery target group for each of a plurality of classifications.

  The progress control unit 332 controls the start and progress of the game, and appropriately instructs the classification unit 331, the display data output unit 333, the main game execution unit 334, the selection unit 335, the association unit 336, and the determination unit 337 to execute the process. To do. The progress control unit 332 exchanges necessary data with the mobile terminal 2 via the server communication unit 31.

  When the request for each screen described with reference to FIGS. 5A to 5C is received from the portable terminal 2, the progress control unit 332 receives a button for receiving an instruction from the player, character information notified to the player, and an image. Each unit is instructed to create display data for displaying the data in a layout corresponding to the screen, and the data is transmitted to the mobile terminal 2. When any button is pressed on the screen displayed on the portable terminal 2 and a request for the next screen corresponding to the button is received from the portable terminal 2, the progress control unit 332 similarly displays the next screen. Each unit is instructed to create data, and the data is transmitted to the portable terminal 2.

  In particular, when an operation for starting a game using the mobile terminal 2 or an operation for transitioning to the home screen is performed by the player and a corresponding home screen request is received from the mobile terminal 2, the progress control unit 332 displays The data output unit 333 is instructed to create display data for displaying the home screen 500. Then, the progress control unit 332 transmits the display data created by the display data output unit 333 to the mobile terminal 2.

  When the main game button 501 is pressed on the home screen 500 displayed on the mobile terminal 2 and a corresponding main game request is received from the mobile terminal 2, the progress control unit 332 sends the main game execution unit 334 to the main game. Is instructed to execute. Then, the progress control unit 332 transmits to the portable terminal 2 display data for displaying a screen for executing the main game created by the main game executing unit 334.

  When the lottery game button 502 is pressed on the home screen 500 displayed on the mobile terminal 2 and a corresponding lottery screen request is received from the mobile terminal 2, the progress control unit 332 displays the lottery game on the display data output unit 333. An instruction to create display data for displaying the screen 510 is given. Then, the progress control unit 332 transmits the display data created by the display data output unit 333 to the mobile terminal 2.

  When the lottery button 512 on the lottery game screen 510 displayed on the portable terminal 2 or the lottery button 524 on the lottery result screen 520 is pressed and a corresponding lottery request is received from the portable terminal 2, the progress control unit 332 The selection unit 335, the association unit 336, and the determination unit 337 are instructed to execute a lottery process. Then, after the lottery process is executed, the progress control unit 332 transmits to the portable terminal 2 display data for displaying the lottery result screen 520 created by the display data output unit 333.

  When the reset button 513 of the lottery game screen 510 displayed on the mobile terminal 2 or the reset button 525 of the lottery result screen 520 is pressed and a corresponding lottery game screen display data request is received from the mobile terminal 2, the progress control is performed. The unit 332 instructs the determination unit 337 to reset the lottery target character card. Further, the progress control unit 332 instructs the display data output unit 333 to create display data for displaying the lottery game screen 510. Then, the progress control unit 332 transmits the display data created by the display data output unit 333 to the mobile terminal 2.

  The display data output unit 333 generates display data for displaying the home screen 500 when the progress control unit 332 is instructed to generate display data for the home screen, and passes the generated display data to the progress control unit 332. .

  Further, the display data output unit 333 generates display data for displaying the lottery game screen 510 when the progress control unit 332 gives an instruction to create display data for the lottery game screen, and the display data output unit 333 performs progress control on the generated display data. Pass to part 332.

  The display data output unit 333 extracts the lottery target group ID associated with the player from the player table based on the player ID included in the lottery game screen request. The display data output unit 333 extracts the lottery target card ID associated with the acquired lottery target group ID with reference to the lottery target group table. Next, the display data output unit 333 calculates the ratio of the number of lottery target card IDs associated with each lottery target group ID to the number of lottery target card IDs associated with all the acquired lottery target group IDs. . The display data output unit 333 outputs the calculated ratio of each lottery target group ID as a winning probability for each of a plurality of groups. For example, when the number of character cards belonging to group A is 12, the number of character cards belonging to group B is 60, and the number of character cards belonging to all groups is 300, each character card is randomly selected with equal probability. Since it is selected, the winning probability of group A is 4% (12/300), and the winning probability of group B is 20% (60/300).

  The display data output unit 333 creates lottery game screen display data for displaying a winning probability, a lottery button, a return button, and the like in a predetermined layout based on the outputted winning probabilities for each of the plurality of groups.

  When the lottery process ends, the display data output unit 333 calculates the next win probability based on the updated lottery target card ID in the player table in the same manner as the above-described win probability, and is given to the player by the lottery process. Display data for displaying the acquired character card and the lottery result screen 520 showing the calculated next-time winning probability is created.

  When execution of the main game is instructed from the progress control unit 332, the main game execution unit 334 creates display data for displaying a screen for executing the main game, and passes the created display data to the progress control unit 332. . Thereafter, the main game is executed in accordance with the operation by the player on the screen for executing the main game displayed on the mobile terminal 2. In the main game, the main game execution unit 334 executes a battle or the like using a card or the like related to the used card information stored in the player table. Further, the main game execution unit 334 updates the game points and the player level in the player table according to the result, grants game points to the player, and raises the player level.

  When the execution control unit 332 instructs the selection unit 335 to execute the lottery process, the selection unit 335 refers to the lottery target group in the player table and, based on the player ID included in the lottery request, the first classification corresponding to the player. Each group ID is extracted. Next, the selection unit 335 reads the lottery target character card IDs belonging to all the extracted group IDs with reference to the lottery target group table. The selection unit 335 randomly selects one character card ID from the read character card IDs with equal probability, and instructs the associating unit 336 to give the character card to the player.

  When the selection unit 335 gives an instruction to give a character card to the player, the associating unit 336 gives the player the character card selected by the selection unit 335 by storing the character card in association with the player. The associating unit 336 gives the character card to the player by adding the card ID of the character card to the player's possessed card information in the player table. The associating unit 336 instructs the determining unit 337 to change the character card included in the lottery target.

  When the association unit 336 instructs the change of the character card included in the lottery object, the determination unit 337 includes the group ID of the first classification to which the character card determined by the selection unit 335 belongs from the lottery target group of the player table. Is deleted. Thereby, in the next lottery game, the character card associated with the deleted group is not included in the lottery object, and only the character card associated with the group other than the deleted group is selected as the lottery object. Therefore, in this lottery game, the character card to be drawn in the next lottery game can be significantly changed.

  In this lottery game, even if a desired character card is not selected by lottery, the probability that the character card will be selected in the next lottery increases dramatically. Each time a lottery is executed, the winning probability of the character card that has not been selected increases, so that the player's expectation for the acquisition of the character card can be sufficiently improved, and the player's willingness to continue the lottery can be improved. It becomes.

  Note that the determination unit 337 may not delete all the character cards corresponding to the group ID to which the selected character card belongs from the next lottery object, but may leave some character cards. In that case, the determination unit 337 determines a character card to be left for the next lottery and a character card to be deleted from the next lottery by random lottery. In the player table, the determination unit 337 stores the card ID of the character card that remains in the lottery object in association with the player ID, and the selection unit 335 stores the card ID of the character card that remains in the lottery object in the next lottery. Is included in the lottery target.

  Further, the determination unit 337 determines the next lottery target character card so as to add the character card corresponding to the group ID to which the character card selected by the selection unit 335 belongs from the lottery target character cards. May be. In that case, the determination unit 337 further adds the same group ID as the group ID to which the character card selected by the selection unit 335 belongs in the first classification of the lottery target group of the player table. As a result, in the next lottery game, the character cards associated with the group to which the selected character card belongs are included twice in the lottery object, and the character card that is the lottery object in the next lottery game is significantly changed. It becomes possible. Thus, since the winning probability of the character card belonging to the same group as the group to which the character card acquired by lottery belongs becomes higher, when the player obtains the desired character card by lottery, the character in the next lottery game It is possible to sufficiently improve the player's expectation for the acquisition of cards and improve the player's willingness to continue the lottery.

  The determination unit 337 determines the next lottery target character card so that only the character card corresponding to the group ID to which the character card lottery selected by the selection unit 335 belongs is included from the lottery target character cards. It may be. In that case, the determination unit 337 deletes a group ID other than the group ID to which the character card selected by the selection unit 335 belongs from the first classification of the lottery target group in the player table. In the next lottery, the selection unit 335 extracts the group ID remaining without deletion of the first classification corresponding to the player and the group IDs of the second classification from the lottery target group of the player table. The group ID remaining without being deleted in the first classification is the group ID to which the character card selected by the selection unit 335 belongs. The selection unit 335 refers to the lottery target group table and extracts the character cards belonging to both the group ID remaining without deletion of the extracted first classification and the group IDs of the second classification as character cards to be lottery. To do.

  Similarly, the determination unit 337 deletes a group ID other than the group ID to which the character card selected by the selection unit 335 belongs from the second classification of the lottery target group in the player table. In the next lottery, the selection unit 335 further includes a group ID remaining without deleting the first category corresponding to the player from the lottery target group of the player table, a group ID remaining without deleting the second category, and the third ID. Each group ID of the classification is extracted. The selection unit 335 refers to the lottery target group table, and includes the group ID remaining without deletion of the extracted first classification, the group ID remaining without deletion of the second classification, and the group IDs of the third classification. Character cards belonging to all are extracted as character cards to be drawn. In this manner, the determination unit 337 narrows down the lottery target character cards every time the lottery is repeated.

  In this case, in the next lottery game, only the character card associated with the group to which the selected character card belongs becomes a lottery target, and the character card targeted for the lottery in the next lottery game can be significantly changed. . Thereby, since the winning probability of the character card belonging to the same group as the group to which the character card acquired by the lottery greatly increases, when the player obtains the desired character card by the lottery, in the next lottery game It is possible to sufficiently improve the player's expectation for the acquisition of the character card and improve the player's willingness to continue the lottery. In this case, the character card to be drawn in the next lottery may be a character card belonging to each group of the two types of classifications extracted most recently. For example, first, in the first lottery, the selection unit 335 reads out the lottery target character card IDs belonging to all the group IDs of the first classification, and selects one character card ID from the read out character card IDs. To do. Next, in the second lottery, the determination unit 337 deletes group IDs other than the group ID to which the character card selected by the selection unit 335 in the first lottery belongs from the first classification of the lottery target group in the player table. To do. The selection unit 335 obtains the character cards belonging to both the group ID remaining without deletion of the first classification extracted from the lottery target group of the player table and the group IDs of the second classification from the lottery target group table for the second time. Extracted as a lottery target character card. The group ID remaining without being deleted in the first classification is a group ID to which the character card selected by the selection unit 335 in the first lottery belongs. Next, in the third lottery, the determination unit 337 deletes group IDs other than the group ID to which the character card selected by the selection unit 335 in the second lottery belongs from the second classification of the lottery target group in the player table. To do. The selection unit 335 selects the character cards belonging to both the group ID remaining without deletion of the second classification extracted from the lottery target group of the player table and the group IDs of the third classification from the lottery target group table for the third time. Extracted as a lottery target character card. Thereby, according to the result of the character card acquired by the lottery, it becomes possible to determine whether or not the player performs the next lottery.

  FIG. 8 is a diagram illustrating an example of an operation sequence related to the lottery game process of the game system 1. This operation sequence cooperates with each element of the portable terminal 2 and the server 3 mainly by the terminal processing unit 25 and the server processing unit 33 based on the programs stored in the terminal storage unit 22 and the server storage unit 32 in advance.

When the progress control unit 332 of the server 3 receives a lottery game screen request from the mobile terminal 2, the display data output unit 333 executes a lottery game screen display data creation process (step S102). Details of the lottery game screen display data creation process will be described later.

  Next, the progress control unit 332 transmits the display data created by the lottery game screen display data creation process to the mobile terminal 2 (step S103). When display data is received from the server 3 via the terminal communication unit 21, the browsing execution unit 251 of the mobile terminal 2 creates drawing data based on the received display data and displays the lottery game screen 510 on the display unit 24. (Step S104).

  Next, in a state where the lottery game screen 510 is displayed on the display unit 24 of the mobile terminal 2, when the player presses the lottery button 512 using the operation unit 23, the browsing execution unit 251 of the mobile terminal 2 A lottery request is transmitted to the server 3 via 21 (step S105). When the progress control unit 332 of the server 3 receives a lottery request from the mobile terminal 2, the selection unit 335, the association unit 336, and the determination unit 337 execute a lottery process (step S106). Details of the lottery process will be described later.

  Next, the display data output unit 333 calculates the next winning probability, and creates display data for displaying the acquired character card given to the player by the lottery process and the lottery result screen 520 showing the calculated next winning probability. (Step S107). Next, the progress control unit 332 transmits the display data created by the display data output unit 333 to the mobile terminal 2 (step S108). When the display data is received from the server 3 via the terminal communication unit 21, the browsing execution unit 251 of the mobile terminal 2 creates drawing data based on the received display data and displays the lottery result screen 520 on the display unit 24. (Step S109). Thus, the operation sequence related to the lottery game process is completed.

  FIG. 9 is a diagram illustrating an example of an operation flow of a lottery game screen display data creation process by the display data output unit 333. The lottery game screen display data creation process shown in FIG. 9 is executed in step S102 of FIG.

  First, the display data output unit 333 calculates a winning probability of each lottery target group based on the player ID, player table, and lottery target group table included in the lottery game screen request (step S201). Next, the display data output unit 333 creates lottery game screen display data based on the calculated winning probability for each group (step S202), and ends a series of steps.

  FIG. 10 is a diagram illustrating an example of an operation flow of a lottery process performed by the selection unit 335, the association unit 336, and the determination unit 337. The lottery process shown in FIG. 10 is executed in step S106 of FIG.

  First, the selection unit 335 specifies the first group ID of the lottery target group from the player table based on the player ID included in the lottery request. The selection unit 335 extracts the card IDs of the character cards associated with all the specified first group IDs from the lottery target group table, and randomly selects one character card from all the character cards with equal probability. (Step S301). Next, the associating unit 336 adds the character card selected by the selecting unit 335 to the player by adding it to the possessed card information of the player table (step S302).

  Next, the determination unit 337 refers to the lottery target group table and identifies the group to which the character card determined by the selection unit 335 belongs (step S303). Next, the determination unit 337 deletes the group ID associated with the identified group from the lottery target group in the player table (step S304), and ends a series of steps.

  As described above, the server 3 can greatly change the game medium to be the next lottery target in units of groups in accordance with the result of selection of the game medium. It is possible to improve the player's expectation. In addition, since the player can change the lottery object of the desired character card by repeating the lottery game, the player can get a sense of nurturing the lottery game.

  Moreover, in the game system 1 of this embodiment, the character card which belongs to the same group as the group to which the character card acquired by the lottery cannot be acquired in the next lottery. Therefore, the player's interest in the lottery game is enhanced, and the continuity of the lottery game can be increased.

  FIG. 11 is a schematic diagram for explaining an example of a lottery game provided by the game system 1 according to another embodiment. In this embodiment, on the lottery game screen, a panel corresponding to each of the lottery target character cards and selectable by the player is displayed, and the character card corresponding to the panel pressed by the player is selected. A panel is an example of an object displayed corresponding to a character card.

  In the example shown in FIG. 11, the lottery target character cards are classified into a plurality of groups (group A, group B, group C, group D) each including four character cards. Group A is a group of low rare cards, and group A includes four low rare cards (character cards A, B, C, and D). Group B is a group of medium rare degree cards, and group B includes four medium rare degree cards (character cards E, F, G, H). Group C is a group of high rarity cards, and group C includes four high rarity cards (character cards I, J, K, and L). Group D is a group of the same high rarity cards as group C, and group D includes four high rarity cards (character cards M, N, O, and P).

  In this embodiment, when the lottery game is executed, a panel corresponding to each character card is displayed. Each panel is randomly arranged in each column in a display frame 1102 having a display column 1101 (for example, 4 columns × 4 rows), and each panel differs for each group to which the corresponding character card belongs. Display color is set. In this way, each panel is displayed so that the player cannot determine which character corresponds to it. When the lottery game using this panel is executed, the panel corresponding to the group to which the character card selected by the lottery game belongs is displayed in an unselectable manner thereafter.

  FIG. 12A is a diagram illustrating an example of a lottery game screen displayed on the display unit 24 of the mobile terminal 2.

  A lottery game screen 1200 shown in FIG. 12A is displayed when the lottery game button 502 is pressed on the home screen 500 shown in FIG. On the lottery game screen 1200, a panel 1201, a return button 1202, and the like are displayed. In the lottery game screen 1200, a winning probability 511 shown in FIG. 5B may be displayed.

  When any one of the plurality of panels 1201 is pressed, a lottery is executed and a screen for displaying a lottery result is displayed. When the return button 1202 is pressed, the home screen 500 is displayed again.

  FIG. 12B is a diagram illustrating an example of a lottery result screen displayed on the display unit 24.

  The lottery result screen 1210 shown in FIG. 12B is displayed when the lottery game is executed by pressing the panel 1201 on the lottery game screen 1200. On the lottery result screen 1210, a panel 1211, an acquired character card image 1212, a name 1213, a lottery game button 1214, and the like are displayed.

  The acquired character card is a character card corresponding to the panel 1201 pressed on the lottery game screen 1200. As the image 1212 and the name 1213, the image and name of the acquired character card are displayed. When the lottery game button 1214 is pressed, a screen for displaying a lottery game screen is displayed. Also on the lottery result screen 1210, a group 522 to which the acquired character card shown in FIG. 5C belongs, a next winning probability 523, and a return button 525 may be displayed.

  FIG. 12C is a diagram illustrating an example of a lottery game screen displayed on the display unit 24.

  The lottery game screen 1220 shown in FIG. 12C is displayed when the lottery game button 1214 is pressed on the lottery result screen 1210. On the lottery game screen 1220, panels 1221 to 1225, a return button 1226, and the like are displayed. Note that the winning probability 511 shown in FIG. 5B may also be displayed on the lottery game screen 1220.

  On the lottery game screen 1220, the panel 1221 corresponding to the acquired character card and the panels 1222, 1223, and 1224 corresponding to the character cards belonging to the same group as the group to which the acquired character card belongs cannot be specified by other players. Displayed in a different color from the panel. On the other hand, a panel (for example, panel 1225) corresponding to a character card that does not belong to the group to which the acquired character card belongs is displayed in the same state as that shown in FIG. 12B so that the player can specify it. Note that the panels 1221 to 1224 may be distinguished from other panels by displaying them smaller than the other panels. Thereby, each player can identify the selectable panel more easily.

  In this embodiment, the display data output unit 333 creates display data for displaying the lottery game screen 1200, the lottery result screen 1210, and the lottery game screen 1220, and passes the created display data to the progress control unit 332. The display data output unit 333 creates display data so that a panel corresponding to a character card belonging to a group different from the lottery target group is displayed in an unselectable manner.

  Thereby, the player can visually recognize a situation in which the character cards to be drawn are drastically reduced in units of groups based on the result of the lottery, and can improve the interest in the lottery game.

  Note that each panel may be associated with a small group to which a plurality of character cards belong instead of a character card. In that case, when a panel is designated by the player, the selection unit 335 specifies a small group corresponding to the panel, and randomly selects a specific character card from the character cards belonging to the small group with equal probability. select.

  In that case, the server 3 does not directly display the lottery result screen 1210 after the panel is designated on the lottery game screen 1200, but information on the small group corresponding to the designated panel (for example, the rare degree), and You may display once the screen (not shown) which displays a lottery button. Thereby, when the player selects a panel corresponding to a small group to which a high-value character card belongs, the player can further improve the sense of expectation for the lottery, so that the interest in the lottery game can be improved.

  Further, the selection unit 335 specifies the character card corresponding to the panel specified by the player by the card ID of the character card included in the lottery request, and instructs the associating unit 336 to give the specified character card to the player. .

  The determination unit 337 may reset the lottery target character card to the initial state when all the lottery target group ID information in the player table has been deleted as a result of the lottery process being executed a plurality of times. Thereby, the lottery game can be continued without being interrupted.

  Moreover, the determination part 337 may restrict | limit the frequency | count of change of the character card of lottery object. In this case, when the number of lottery processes exceeds a predetermined number (for example, three times), the determining unit 337 does not change the character card to be lottered in the subsequent lottery processes. Thereby, the player can have a new enjoyment of determining whether or not to repeat the lottery by determining whether or not the character card desired by the user is included in the lottery object by a predetermined number of lotteries.

  Further, the display data output unit 333 may create display data so as to display the winning probability 511 and the next winning probability 523 as a gauge display. In that case, when the winning probability and the next winning probability exceed a certain value (for example, 50%), the display data output unit 333 turns on the gauges related to the winning probability 511 and the next winning probability 523, increases the brightness, displays animation, etc. The display mode may be changed. Thereby, the visibility of the winning probability of the character cards belonging to each group is improved, and it is easy to determine whether to continue the lottery game.

  Further, the determination unit 337 may change the number of groups or character cards to be deleted or added from the lottery target group of the player table according to the player level or the number of related player IDs stored in the player table. In that case, the determination unit 337 deletes or adds a large number of groups or character cards as the player level or the number of related players increases. Each player can increase the player level or the number of related players so that the lottery object changes dramatically in the lottery game, so that the main game and communication between the players can be activated.

  Further, the server 3 may share the lottery target character card among the related players. In that case, when the player executes the lottery, the server 3 displays a screen for selecting the player or a related player of the player on the portable terminal 2 of each player. And the server 3 performs lottery with respect to the lottery object group corresponding to the selected player, and updates the lottery object group corresponding to the selected player according to the lottery result. By doing in this way, in a lottery game, cooperation with a related player can be performed and interest property improves more.
