The server updates game data and transmits information to the mobile terminal based on information transmitted from the mobile terminal via the browser.

  The games provided by the server include a main game and a lottery game which is another game different from the main game. The server executes, as a main game, a quest that proceeds according to a game scenario. The quest is generally called a search, a mission, or the like. For example, a quest has a plurality of floors (stages) in each of a plurality of dungeons and sequentially executes processing of each floor. In the processing of each floor, a battle (competition) between the player character and the enemy character, a privilege such as a specific game content is provided to the player, a so-called RAID battle in which a plurality of players participate, an encounter with another player, and / or Battles (competitions) with other players are included. The player character is a game medium owned by the player, and the enemy character is a non-player character or a game medium owned by another player.

  The game medium is electronic data used in the game, and includes, for example, cards, items, characters, avatars, and the like. The game medium is electronic data that can be acquired, retained, used, managed, exchanged, synthesized, strengthened, sold, discarded, and / or given by the player in the game as the game progresses. The usage mode of the game content is not limited to the one specified in this specification. The player can grow the character and acquire items by executing the quest.

  In the present embodiment, a card registered in the game system in advance will be described as an example of a game medium. The player character or enemy character card used in the battle has battle parameters. The parameters for battle include, for example, attack power, defense power, physical strength (or HP (hit point)), attribute (for example, fire, water, lightning, etc.), rarity (for example, normal, rare, S (super) rare, SS (double super) rare, SSS (triple super) rare, legend, etc.), activation rate of skills (special effects), attack speed (number of attacks in one turn, number of turns to attack, etc.), number of defenses in a single match And / or jobs (eg, occupation, type of service, 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 to select a character card from a plurality of character cards set as a lottery target according to a request from a player operating the mobile terminal, and associates the selected character card with the player. By giving and storing, it is 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. In addition, each group may be classified according to the attribute of the character, the time or event when the character card is issued, or the item worn by the character. The request from the player is a lottery request related to an instruction to execute a lottery to the server. When the server receives the lottery request from the player, the server randomly selects a character card from the character cards targeted for the lottery with equal probability.

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

  In the next lottery, the server may further add (supplement) character cards belonging to the same group as the group to which the selected character card belongs to the character cards to be selected. Further, the server may set only the character card belonging to the same group as the group to which the selected character card belongs as the character card to be subjected to the next lottery.

  This makes it possible to greatly change the card to be the next lottery in a group unit according to the result of executing the lottery, and to improve the player's sense of expectation for acquiring the card. Further, by branching the next card to be drawn according to the result of the lottery, the player's willingness to continue the lottery game is improved.

You. Group A is a group of low-rare cards such as character cards with the lowest (normal) rarity, and group A includes four low-rare cards of different types (character cards A, B, and C, respectively). , D) are included. Group B is a group of medium-rare cards such as character cards with medium-rare (rare), for example. Group B includes three medium-rare cards of different types (character cards E, F, and G, respectively). ) Is included. The group C is a group of high rarity cards such as character cards having the highest rarity (super rare). The group C includes two high rarity cards (character cards H and I) of different types. included. Group D is a group of high-rare cards such as character cards with the highest rarity (super rare), the same as group C. Group D includes two cards of different types from each card included in group C. High rarity cards (character cards J and K) are included.

  The server 3 executes a lottery process of randomly selecting character cards at random with equal probability from among the character cards to be drawn which belong to the groups A to D. When the character card B is selected as a result of the lottery process, the server 3 gives the selected character card B to the player. In that case, the server 3 specifies a group (group A) to which the selected character card B belongs. The server 3 deletes the character cards (character cards A, B, C, and D) belonging to the specified group A from the character cards to be drawn, and sets the remaining character cards as the next character cards to be drawn.

The related player is, for example, another player belonging to the same group to which the player belongs, another player having a friend relationship with the player, another player who has rescued the player in a battle with a past enemy character, or played in the past Other players who have played and / or other players who belong to a group that has played in the past.

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

  FIG. 7C shows a lottery target group table for managing a group to which a character card classified in the lottery game belongs. In the lottery target group table, for each character card to be subjected to the lottery, the card ID of the character card, the group ID indicating the group to which the character card belongs, and the like are stored in association with each other. Note that each group is set for each of a plurality of classifications.

  Note that each group in one classification may be set according to different types of rules. For example, in the first category, the first group is a group having a normal rarity, the second group is a group having an attribute of fire, and the third group is a group of character cards issued this month. May be classified as follows. Further, each classification may be set according to the same type of rule. For example, a group may be set according to the degree of rarity in both the first class and the second class. Further, 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 having a normal rarity 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, these units may be implemented in the server 3 as firmware.

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

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

  In addition, the classification unit 331 sets an initial value of the lottery target group to be subjected to the lottery process. The classification unit 331 stores, for each of a plurality of classifications, all group IDs defined in each classification as initial values of the lottery target group.

  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 processing. I 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 mobile terminal 2, the progress control unit 332 includes a button for receiving an instruction from the player, character information to be notified to the player, and an image. And the like, and instruct each unit to create display data for displaying the data in a layout corresponding to the screen, and transmit the data to the mobile terminal 2. Then, when any button is pressed on the screen displayed on the mobile terminal 2 and a request for the next screen corresponding to the button is received from the mobile 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 mobile terminal 2.

  In particular, when an operation of starting a game using the mobile terminal 2 or an operation of 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 It instructs the data output unit 333 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 causes the main game execution unit 334 to display the main game button. To execute Then, the progress control unit 332 transmits the display data for displaying the screen for executing the main game, created by the main game execution unit 334, to the mobile terminal 2.

  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 causes the display data output unit 333 to display the lottery game button. The user instructs creation of display data for displaying the 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.

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

  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 character card to be drawn. 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 creates display data for displaying the home screen 500 when the creation of the home screen display data is instructed from the progress control unit 332, and passes the created display data to the progress control unit 332. .

  In addition, when the creation of display data of the lottery game screen is instructed from the progress control unit 332, the display data output unit 333 creates display data for displaying the lottery game screen 510, and controls the created display data to progress control. To the unit 332.

  The display data output unit 333 extracts a 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 refers to the lottery target group table and extracts the lottery target card ID associated with the acquired lottery target group ID. 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 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 the 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 assigned with equal probability. Since the selection is made, the winning probability of the group A is 4% (12/300), and the winning probability of the 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 output winning probabilities for each of the plurality of groups.

  When the lottery process is completed, the display data output unit 333 calculates the next winning probability based on the updated lottery target card ID of the player table in the same manner as the above-mentioned winning probability, and is provided to the player by the lottery process. Display data for displaying the obtained character card and the lottery result screen 520 indicating the calculated next winning probability are created.

  When the execution of the main game is instructed by 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 an operation by the player on the screen for executing the main game displayed on the mobile terminal 2. The main game execution unit 334 executes a battle or the like in the main game using a card or the like related to the used card information stored in the player table. The main game execution unit 334 updates the game points and the player level in the player table according to the result, gives the game points to the player, and raises the player level.

  When the execution control unit 332 instructs the execution of 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, of the first classification corresponding to the player. Extract each group ID. Next, the selection unit 335 reads the lottery target character card ID 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 association unit 336 to give the character card to the player.

  When the selection unit 335 instructs to give the character card to the player, the association unit 336 associates the character card selected by the selection unit 335 with the player, stores the character card, and gives the character card to 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 a change of a character card included in a lottery target is instructed from the association unit 336, the determination unit 337 determines, from the lottery target group in the player table, the first class group ID to which the character card determined by the selection unit 335 belongs. Remove. Thus, in the next lottery game, character cards associated with the deleted group are not included in the lottery target, and only character cards associated with groups other than the deleted group are selected as the lottery target. Therefore, in this lottery game, it is possible to significantly change the character card targeted for the lottery in the next lottery game.

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

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

  Further, the determination unit 337 determines the next character card to be subjected to the lottery so as to add a character card corresponding to the group ID to which the character card selected by the selection unit 335 belongs from the character cards to be selected. You may. 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 in the player table. As a result, in the next lottery game, the character card associated with the group to which the selected character card belongs is included twice in the lottery target, and the character card targeted for the lottery in the next lottery game is greatly changed. It becomes possible. As described above, since the winning probability of the character cards belonging to the same group as the group to which the character card obtained by the lottery belongs increases, if the player obtains the desired character card by the lottery, the character in the next lottery game It is possible to sufficiently improve the player's sense of expectation for acquiring a card, and to improve the player's willingness to continue the lottery.

  Note that the determination unit 337 determines the next character card to be drawn from among the character cards to be drawn, so that only the character card corresponding to the group ID to which the character card drawn by the selection unit 335 belongs is included. 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, from the lottery target group in the player table, the group ID of the first category corresponding to the player that has not been deleted and the group ID of the second category. It should be noted that the group ID that remains in the first category without being deleted is the group ID to which the character card selected by the selection unit 335 belongs. The selecting unit 335 refers to the lottery target group table and extracts character cards belonging to both the extracted group IDs of the first class that have not been deleted and the group IDs of the second class as character cards to be selected. I 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 determines, from the lottery target group in the player table, the group ID of the first classification corresponding to the player that has not been deleted, the group ID that has not been deleted of the second classification, and the third ID. Each group ID of the classification is extracted. The selection unit 335 refers to the lottery target group table, and displays the extracted group IDs of the first class that remain without being deleted, the second class that remains without being deleted, and the group IDs of the third class. Character cards belonging to all are extracted as character cards to be drawn. In this manner, the determination unit 337 narrows down the character cards targeted for the lottery each 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 to be drawn in the next lottery game can be significantly changed. . As a result, the winning probability of a character card belonging to the same group as the group to which the character card obtained by the lottery belongs increases dramatically, so if the player obtains the desired character card by the lottery, the next lottery game It is possible to sufficiently improve the player's sense of expectation for obtaining the character card, and to 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 classification extracted most recently. For example, first, in the first lottery, the selection unit 335 reads out the character card IDs of the lottery targets belonging to all the group IDs of the first classification, and selects one character card ID from the read character card IDs. I do. Next, in the second lottery, the determination unit 337 deletes a group ID other than the group ID to which the character card selected in the first lottery by the selection unit 335 belongs from the first classification of the lottery target group in the player table. I do. The selection unit 335 assigns the character cards belonging to both the group IDs of the first classification extracted from the lottery target group in the player table that have not been deleted and the group IDs of the second classification to the second time from the lottery target group table. It is extracted as a character card to be drawn. Note that the group ID that remains in the first category without being deleted is the 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 a group ID other than the group ID to which the character card selected in the second lottery by the selection unit 335 belongs from the second classification of the lottery target group in the player table. I do. The selecting unit 335 assigns the character cards belonging to both the group IDs of the second classification extracted from the lottery target group in the player table that have not been deleted and the group IDs of the third classification to the third time from the lottery target group table. It is extracted as a character card to be drawn. This makes it possible for the player to determine whether or not to perform the next lottery, based on the result of the character card obtained by the lottery.

  FIG. 8 is a diagram showing an example of an operation sequence related to the lottery game process of the game system 1. This operation sequence is mainly performed by the terminal processing unit 25 and the server processing unit 33 in cooperation with each element of the mobile terminal 2 and the server 3 based on a program stored in the terminal storage unit 22 and the server storage unit 32 in advance. And executed.

  First, when the player presses the lottery game button 502 using the operation unit 23 while the home screen 500 is displayed on the display unit 24 of the mobile terminal 2, the browsing execution unit 251 of the mobile terminal 2 causes the terminal communication unit 21 A lottery game screen request is transmitted to the server 3 via the server (step S101). When the progress control unit 332 of the server 3 receives the 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 processing 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 causes the terminal communication unit The lottery request is transmitted to the server 3 via the server 21 (step S105). When the progress control unit 332 of the server 3 receives the 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 indicating 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 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 ends.

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

  First, the display data output unit 333 calculates the winning probability of each of the lottery target groups based on the player ID, the player table, and the 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 in 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 selecting unit 335 extracts, from the lottery target group table, card IDs of the character cards associated with all the specified first group IDs, 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 card by adding the character card to the owned card information in the player table (step S302).

  Next, the determining unit 337 refers to the lottery target group table and specifies the group to which the character card determined by the selecting unit 335 belongs (Step S303). Next, the determining unit 337 deletes the group ID associated with the specified 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 significantly change the game content to be subjected to the next lottery in a group unit according to the result of the selection of the game content. It is possible to improve the player's sense of expectation. Further, the player can change the lottery target of the desired character card by repeating the lottery game, so that the player can have a feeling of nurturing the lottery game.

  Further, in the game system 1 of the present embodiment, a character card belonging to the same group as the group to which the character card obtained by the lottery belongs cannot be obtained in the next lottery. Therefore, the interest of the player in the lottery game is increased, 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, a panel corresponding to each character card to be selected and selected by the player is displayed on the lottery game screen, and the character card corresponding to the panel pressed by the player is selected. The panel is an example of an object displayed corresponding to the character card.

  In the example shown in FIG. 11, the character cards to be drawn are classified into a plurality of groups (group A, group B, group C, and group D) each including four character cards. Group A is a group of low-rareness cards. Group A includes four low-rareness cards (character cards A, B, C, and D). The group B is a group of medium rare cards, and the group B includes four medium rare cards (character cards E, F, G, and H). Group C is a group of high-rareness cards, and group C includes four high-rareness cards (character cards I, J, K, and L). The group D is a group of the same high-rareness cards as the group C. The group D includes four high-rareness 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 is different for each group to which the corresponding character card belongs. The display color is set. In this way, each panel is displayed so that the player cannot determine which character it corresponds to. 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 as unselectable 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.

  The 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. Note that the winning probability 511 shown in FIG. 5B may be displayed on the lottery game screen 1200.

  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.

  A lottery result screen 1210 shown in FIG. 12B is displayed when the panel 1201 is pressed on the lottery game screen 1200 and the lottery game is executed. On the lottery result screen 1210, a panel 1211, an image 1212 of the obtained character card, 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 the 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. Note that the group 522 to which the acquired character card belongs, the next winning probability 523, and the return button 525 shown in FIG. 5C may also be displayed on the lottery result screen 1210.

  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. Panels 1221 to 1225, a return button 1226, and the like are displayed on the lottery game screen 1220. 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 are assigned to other panels so that the player cannot specify them. It is 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 displayed smaller than the other panels so that they can be distinguished from other panels. This allows each player to more easily identify selectable panels.

  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 as to display a panel corresponding to a character card belonging to a group different from the lottery target group in a non-selectable manner.

  This allows the player to visually recognize the situation in which the character cards to be drawn are dramatically reduced in group units based on the result of the lottery, thereby improving the interest in the lottery game.

  In addition, what is associated with each panel may be a small group to which a plurality of character cards belong, instead of a character card. In this case, when the player specifies a panel, 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, after the panel is designated on the lottery game screen 1200, the server 3 does not directly display the lottery result screen 1210, but information (for example, rarity) on the small group corresponding to the designated panel, and A screen (not shown) for displaying a lottery button may be displayed once. Thus, when the player selects the panel corresponding to the small group to which the high-value character card belongs, the player can further improve the expectation for the lottery, thereby improving the interest in the lottery game.

  In addition, the selection unit 335 specifies the character card corresponding to the panel specified by the player based on the card ID of the character card included in the lottery request, and instructs the association unit 336 to give the specified character card to the player. .

  In addition, when all pieces of information of the lottery target group ID in the player table are deleted by executing the lottery processing a plurality of times, the determination unit 337 may reset the character card to be subjected to the lottery to the initial state. This allows the lottery game to be continued without interruption.

  In addition, the determination unit 337 may limit the number of times the character card to be drawn is changed. In this case, when the number of lottery processes exceeds a predetermined number (for example, three), the determination unit 337 does not change the character card to be selected in the subsequent lottery process. This allows the player to have a new enjoyment of determining whether or not to repeat the lottery, depending on whether or not the lottery target includes the character card desired by the user by the predetermined number of lotteries.

  The display data output unit 333 may create display data so that the winning probability 511 and the next winning probability 523 are displayed on a gauge. In this 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, and the like. May be changed to the display mode. Thereby, the visibility of the winning probability of the character cards belonging to each group is improved, and it is easy to determine whether the lottery game is continued.

  In addition, the determination unit 337 may change the number of groups or character cards to be deleted or added from the lottery target group in 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 larger number of groups or character cards as the player level or the number of related players increases. Since each player increases the player level or the number of related players so that the lottery target changes drastically in the lottery game, it is possible to activate communication between the main game and each player.

  In addition, the server 3 may share the character card to be drawn between the related players. In that case, the server 3 causes the portable terminal 2 of each player to display a screen for selecting the player or a player related to the player when the player executes the lottery. Then, the server 3 executes a lottery for the lottery target group corresponding to the selected player, and updates the lottery target group corresponding to the selected player according to the lottery result. By doing so, it is possible to cooperate with the related player in the lottery game, and the interest is further improved.

Alternatively, the main game execution unit 334 may set the game points given to the player in the main game as a privilege to be larger than the points normally given. This allows each player to execute the lottery game more frequently so that the main game can be more advantageously advanced, so that the entire game can be activated.

For example, the lottery game media may be set so that the player can only browse or provide it to other players.

  Further, each function of the server processing unit 33 described above may be executed by the terminal processing unit 25 of the mobile terminal 2. In this case, if the player table, the card table, and the lottery target group table are stored in the terminal storage unit 22, there is no need to communicate with the server 3 each time the processing is performed, and the above functions can be realized only by the mobile terminal 2. Is also possible. The game executed on the mobile terminal 2 may be a hybrid game in which each of the server 3 and the mobile terminal 2 performs a part of the processing. In this case, for example, each screen relating to the progress of the game is displayed as a web display displayed on the mobile terminal 2 based on the display data generated by the server 3, and other menu screens and the like are displayed on the native application installed on the mobile terminal 2. And native display.
