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

The game provided by the server includes a main game and a lottery game which is another game different from the main game. As the main game, the server executes quests that progress according to the scenario of the game. A quest is generally also called a search, a mission, or the like, and has a plurality of floors (stages) in each of a plurality of dungeons, and processes of each floor are sequentially executed. In the processing of each floor, a battle (competition) between a player character and an enemy character, granting a privilege such as a specific game medium to a player, a so-called RAID battle in which multiple players participate, an encounter with another player, and / or Includes battles 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.

The game medium is electronic data used in a game, and includes, for example, cards, items, characters, avatars, and the like. Further, the game medium is electronic data that can be acquired, owned, used, managed, exchanged, synthesized, strengthened, sold, discarded, and / or gifted by the player in the game according to the progress of the game. The usage mode of the game medium is not limited to that specified in the present specification. By executing the quest, the player can grow the character and acquire the item.

In this 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 are, for example, attack power, defense power, physical strength (or HP (hit point)), attribute (for example, fire, water, thunder, etc.), rarity (for example, normal, rare, S (super) rare, etc.). SS (double super) rare, SSS (triple super) rare, legend, etc.), skill (special effect) activation rate, attack speed (number of attacks per turn, number of turns until attack, etc.), number of defenses in a pair of battles Parameters and / or jobs (eg, occupation, type of soldier, etc.). Further, 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.

Further, as a lottery game, the server executes a lottery to select a character card from a plurality of character cards set as lottery targets according to a request from a player operating a mobile terminal, and the selected character card is used by the player. It is given to the player by storing it in association with. That is, in this lottery, a game medium that can be associated and stored is set as the game medium to be drawn. In this lottery, the selected character card given to the player is left without being excluded from the lottery target. That is, in the next lottery, the server reselects a character card from a plurality of character cards set as lottery targets, including a character card of the same type as the given character card, according to a request from the player. Then, the server changes the winning probability of the specific character card in the next lottery according to the number of times the lottery is executed according to the request from each player.

The specific character card whose winning probability is changed is a featured card that is the centerpiece of the lottery game, and is predetermined by the operator of the game system. The featured cards are, for example, a character card with the highest rarity, a character card with a specific special effect, a card that can be acquired only at a specific time (seasonal or event limited card), and a plurality of characters set as lottery targets. It is the most valuable character card among the character cards. The winning probability of the eyeball card is reset when the eyeball card is selected and given to the player. The winning probability is reset by resetting to the initial value of the winning probability, that is, the winning probability when the lottery is first executed. This makes it possible to flexibly change the winning probability of the eyeball card according to the number of times the lottery is executed, and to improve the player's expectation for the acquisition of the eyeball card.

2.1.1. Function of Terminal Processing Unit 25 FIG. 3 is a schematic diagram for explaining a lottery game provided by the game system 1.

As shown in FIG. 3, in the lottery game by the game system 1, the character cards to be drawn are classified into a plurality of groups (group 301, group 302, group 303) including two or more character cards. Group 301 is a group of eye-catching cards such as character cards having the highest rarity (super rare), and group 301 includes 10 eye-catching cards of different types. Group 302 is a group of medium rarity cards such as character cards having a medium rarity (rare), and group 302 includes 10 medium rarity cards of different types. The group 303 is a group of low rarity cards such as a character card having the lowest rarity (normal), and the group 303 includes 80 low rarity cards of different types.

It should be noted that each group may not be classified according to the rarity of the character card, but may be classified according to the time or event when the character card was issued, the item worn by the character, or the like.

Winning probabilities 311 to 313 are assigned to each group 301 to 303, respectively. The initial value of the winning probability 311 of the group 301 is 1%, the initial value of the winning probability 312 of the group 302 is 19%, and the initial value of the winning probability 313 of the group 303 is 80%. The server 3 randomly selects a group according to the winning probabilities 311 to 313 assigned to each group 301 to 303. That is, in the first lottery step, the group 301 is selected with a probability of 1%, the group 302 is selected with a probability of 19%, and the group 303 is selected with a probability of 80%. The lottery step represents the order of each lottery, and the first lottery step corresponds to the first lottery. Further, the server 3 randomly selects a character card from each character card included in the selected group with an equal probability. Then, the server 3 gives the selected character card to the player.

Only one character card may be included in the group. If a group containing only one character card is selected, one character card included in that group is given to the player.

In this lottery game, the types of character cards given do not decrease. That is, the selected character card given to the player remains as a lottery target without being deleted from each group in the second and subsequent lottery (or the given character card is once deleted from each group and is the same again. Kind of character card is replenished). Further, in this lottery game, in the second and subsequent lottery, the winning probabilities 311 to 313 in which each group 301 to 303 are selected are changed according to the number of lottery executions up to that point. The server 3 increases the winning probability 311 in which the group 301 of the eyeball card is selected in the second and subsequent lottery, and lowers the winning probability 312 and 313 in which the other groups 302 and 303 are selected by that amount. I will do it. That is, in the second lottery step, the group 301 is selected with a probability of 1.01%, the group 302 is selected with a probability of 18.998%, and the group 303 is selected with a probability of 79.992%. Further, in the 99th lottery step, the group 301 is selected with a probability of 50%, the group 302 is selected with a probability of 9.596%, and the group 303 is selected with a probability of 40.404%.

In this lottery game, the winning probability of the eyeball card 311 increases each time the lottery is executed, so that the player's expectation for the acquisition of the eyeball card can be sufficiently improved and the player's willingness to continue the lottery can be improved. It will be possible. Further, the server 3 monotonically increases the increase value (difference value with respect to the previous winning probability) or the increase rate (ratio to the previous winning probability) of the winning probability 311 of the featured card in the second and subsequent lottery, and the like. Since the probability can be changed flexibly, it is possible to further improve the player's expectation for the acquisition of the centerpiece card. Alternatively, the server 3 can monotonically reduce the increase value or the increase rate of the winning probability 311 of the eyeball card in the second and subsequent lottery, and can set the upper limit value of the winning probability 311. It is also possible to improve.

The character cards included in each group are subject to lottery in the lottery game. The winning probability of each character card included in each group is determined based on the initial value of the winning probability associated with the group and the number of lottery executions associated with each player, and is given to each character card. In the group table, the winning probability for each number of lottery executions may be associated and stored for each group.

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

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

Upon receiving the request for each screen described with reference to FIGS. 4A to 4C from the mobile terminal 2, the progress control unit 331 has a button for receiving an instruction from the player, character information to be notified to the player, and an image. Instruct each part to create display data for displaying etc. 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 the request for the next screen corresponding to the button is received from the mobile terminal 2, the progress control unit 331 similarly displays the next screen. Instruct each part to create data, and send the data to the mobile terminal 2.

In particular, when the player performs an operation of starting a game using the mobile terminal 2 or an operation of transitioning to the home screen and a home screen request corresponding to the operation is received from the mobile terminal 2, the progress control unit 331 displays. Instruct the data output unit 332 to create display data for displaying the home screen 400. Then, the progress control unit 331 transmits the display data created by the display data output unit 332 to the mobile terminal 2.

Further, when the main game button 401 is pressed on the home screen 400 displayed on the mobile terminal 2 and the corresponding main game request is received from the mobile terminal 2, the progress control unit 331 sends the main game to the main game execution unit 333. Instruct to execute. Then, the progress control unit 331 transmits the display data for displaying the screen for executing the main game created by the main game execution unit 333 to the mobile terminal 2.

Further, when the lottery game button 402 is pressed on the home screen 400 displayed on the mobile terminal 2 and the corresponding lottery screen request is received from the mobile terminal 2, the progress control unit 331 causes the selection unit 334 to display the lottery game screen 410. Instructs the creation of display data for displaying. Then, the progress control unit 331 transmits the display data created by the selection unit 334 to the mobile terminal 2.

Further, when the lottery button 413 is pressed on the lottery game screen 410 displayed on the mobile terminal 2 and the corresponding lottery request is received from the mobile terminal 2, the progress control unit 331 instructs the selection unit 334 to execute the lottery. do. Then, the progress control unit 331 transmits the display data for displaying the lottery result screen 420 created by the selection unit 334 to the mobile terminal 2.

Further, when the detail button 414 is pressed on the lottery game screen 410 displayed on the mobile terminal 2 and the corresponding detail screen request is received from the mobile terminal 2, the progress control unit 331 displays the detail screen 430 on the selection unit 334. Instruct to create display data for display. Then, the progress control unit 331 transmits the display data created by the selection unit 334 to the mobile terminal 2.

When the progress control unit 331 instructs the display data output unit 332 to create the display data of the home screen, the display data output unit 332 creates the display data for displaying the home screen 400 and passes the created display data to the progress control unit 331. ..

When the progress control unit 331 instructs the main game execution unit 333 to execute the main game, the main game execution unit 333 creates display data for displaying the screen for executing the main game, and passes the created display data to the progress control unit 331. .. After that, the main game is executed according to 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 333 executes a battle or the like using a card or the like related to the use ID stored in the player table. Further, the main game execution unit 333 updates the game points and the player level in the player table according to the result, grants the game points to the player, and raises the player level.

When the progress control unit 331 instructs the selection unit 334 to create the lottery game screen 410, the selection unit 334 specifies the player ID included in the lottery screen request, and from the player table, the number of lottery executions associated with the specified player ID is calculated. read out. Further, the selection unit 334 reads out the initial value of the winning probability of each group from the group table. The selection unit 334 calculates the winning probability of each group in the next lottery to be executed based on the read initial value and the number of lottery executions. The selection unit 334 creates display data for displaying the lottery game screen 410 showing the read lottery execution number and the calculated winning probability, and passes the created display data to the progress control unit 331.

The selection unit 334 changes the winning probability of the featured card in the next lottery according to the request from the player according to the number of times the lottery is executed by the player. The selection unit 334 changes the winning probability so that the winning probability of the group of the centerpiece card increases as the number of lottery executions increases, and the winning probability of the other group decreases accordingly.

For example, the winning probabilities of the centerpiece card group 301, the medium rarity card group 302, and the low rarity card group 303 shown in FIG. 3 at the number of times the lottery is executed are calculated by the following formula.
Winning probability of group 301 P ₁ = A ₁ x 100 / (100-number of lottery executions)
Winning probability of group 302 P ₂ = (1-P ₁ ) × (A ₂ / (1-A ₁ ))
Winning probability of group 303 P ₃ = (1-P ₁ ) × (A ₃ / (1-A ₁ ))
Here, A ₁ is the initial value of the winning probability of the group 301, A ₂ is the initial value of the winning probability of the group 302, and A ₃ is the initial value of the winning probability of the group 303.

Hereinafter, a case where the winning probability P ₁ of the group 301 is 1%, the winning probability P ₂ of the group 302 is 19%, and the winning probability P ₃ of the group 303 is 80% will be described as an example. When the number of lottery executions is 0 (the lottery step is 1), the winning probability of the group 301 is 1%, the winning probability of the group 302 is 19%, and the winning probability of the group 303 is 80%. On the other hand, when the number of lottery executions is 1 (the lottery step is 2), the winning probability of the group 301 is 1.01%, the winning probability of the group 302 is 18.998%, and the winning probability of the group 303 is 79.992%. Will be. When the number of lottery executions is 98 (the lottery step is 99), the winning probability of the group 301 is 50%, the winning probability of the group 302 is 9.596%, and the winning probability of the group 303 is 40.404%. .. In this calculation formula, the increase value and the increase rate of the winning probability of the eyeball card are monotonously increased with respect to the number of lottery executions, so that the winning probability of the eyeball card increases dramatically as the player executes the lottery. Therefore, it is possible to improve the player's willingness to continue the lottery game.

The selection unit 334 may change the winning probability of each group by a method different from the above calculation formula. For example, the selection unit 334 may change the winning probability so that the increase value or the increase rate of the winning probability of the eyeball card is monotonously decreased with respect to the number of lottery executions. As a result, the winning probability of the eyeball card becomes a high value to some extent in the initial stage, and it becomes easy for a light user who executes a lottery game only a little to acquire the eyeball card. Therefore, it is possible to increase the number of participants in the lottery game by having more light users participate in the lottery game.

Alternatively, the selection unit 334 may change the winning probability so that the winning probability of the featured card is linear with respect to the number of lottery executions. In that case, the selection unit 334 sets, for example, the winning probability of the eyeball card to 1% in the first lottery step, 2% in the second lottery step, and 99% in the 99th lottery step. This simplifies the transition of the winning probability of the featured card, and the player can easily grasp the current winning probability.

Further, the selection unit 334 uses the character, attribute, rarity or group of the character card selected in the lottery, the relationship between the character card selected in the lottery and the character card owned by the player, and the character card selected in the lottery. Even if the degree of changing the winning probability is changed based on the relationship between the main card and the points given to the player in the main game, the level of the player in the main game, or the number of messages sent by the player to other players. good. In addition, the selection unit 334 increases the degree of increase in the winning probability by advancing (increasing) the lottery step by two or more steps in one lottery, and decreases the winning probability by returning (decreasing) the lottery step. can do. Further, the selection unit 334 can prevent the winning probability from being changed by not changing the lottery step after the lottery.

For example, the selection unit 334 determines the next winning probability when the character, attribute, rarity or group of the character card selected in the lottery is the same as the predetermined character, attribute, rarity or group. , Make it larger than the next winning probability if they are not the same. Further, the selection unit 334 makes the next winning probability when the character card selected in the lottery is the same as the character card already owned by the player higher than the next winning probability when they are not the same. Further, the selection unit 334 makes the next winning probability when the character or attribute of the character card selected in the lottery and the eyeball card are the same is larger than the next winning probability when they are not the same. As a result, even if the eyeball card is not won, the probability of winning the next time may be greatly improved, so that it is possible to improve the player's expectation for the acquisition of the eyeball card.

Further, for example, in the selection unit 334, the higher the game point or player level stored in the player table, the higher the degree of increase in the winning probability in each step, and the lower the game point or player level, the smaller the degree of increase in the winning probability. Change the degree of increase in the winning probability so that it becomes. As a result, each player executes the main game more frequently in order to improve the degree of increase in the winning probability, so that it is possible to activate the main game.

Further, for example, the selection unit 334 increases the winning probability as the number of messages sent by the player to the related player or the number of messages sent by the player to the main game to the other player increases. Change the degree of increase in. As a result, each player sends more messages in order to improve the degree of increase in the winning probability, so that it is possible to activate communication between the players.

Further, the selection unit 334 sets an initial value immediately after resetting the winning probability based on the points given to the player in the main game, the level of the player in the main game, or the number of messages sent by the player to other players. You may change it. The selection unit 334 can dynamically change the initial value of the winning probability by setting the lottery step immediately after resetting the winning probability to a step other than 1.

For example, in the selection unit 334, the higher the game point or player level stored in the player table, the larger the initial value of the winning probability, and the lower the game point or the player level, the smaller the initial value of the winning probability. Change the initial value of winning probability. As a result, each player executes the main game more frequently in order to improve the initial value of the winning probability, so that the main game can be activated.

Further, for example, the selection unit 334 wins so that the initial value of the winning probability increases as the number of messages sent by the player to the related player or the number of messages sent by the player to the main game to the other player increases. Change the initial value of probability. As a result, each player sends more messages in order to improve the initial value of the winning probability, so that it is possible to activate communication between the players.

Further, in the above formula, when the number of lottery executions is 99, the winning probability of the group 301 is 100%, and the centerpiece card is always won. Therefore, the selection unit 334 sets an upper limit on the winning probability of the centerpiece card. For example, the selection unit 334 sets the upper limit of the winning probability to 50%, and sets the winning probability of each group when the number of lottery executions is 99 or more (the 100th and subsequent lottery steps), and the number of lottery executions is 98 (99th). Set to the same value as the winning probability in the case of the lottery step). By setting the upper limit of the winning probability, it is possible to prevent the winning probability from becoming too high and the player's expectation for the acquisition of the centerpiece card from decreasing.

The selection unit 334 uses the character, attribute, rarity or group of the character card selected in the lottery, the relationship between the character card selected in the lottery and the character card owned by the player, and the character card selected in the lottery. The upper limit of the winning probability may be set based on the relationship between the main card and the centerpiece card, the points given to the player in the main game, the level of the player in the main game, or the number of messages sent by the player to other players. .. The selection unit 334 can change the upper limit of the winning probability by changing the maximum number of lottery steps.

For example, the selection unit 334 is the upper limit of the winning probability when the character, attribute, rarity or group of the character card selected in the lottery is the same as the predetermined character, attribute, rarity or group. Is set to a value higher than the current upper limit. Further, when the character card selected in the lottery is the same as the character card already owned by the player, the selection unit 334 sets the upper limit value of the winning probability to a value higher than the upper limit value of the current winning probability. Further, when the character or attribute of the character card selected in the lottery and the eyeball card are the same, the selection unit 334 sets the upper limit value of the winning probability to a value higher than the current upper limit value. As a result, even if the eyeball card is not won, the upper limit of the winning probability may be high, so that it is possible to improve the player's expectation for the acquisition of the eyeball card.

Further, for example, the selection unit 334 sets the upper limit of the winning probability so that the higher the game point or the player level stored in the player table, the higher the upper limit of the winning probability, and the lower the game point or the player level, the higher the winning probability. Set the upper limit of the winning probability so that the upper limit of the probability is low. As a result, each player executes the main game more frequently in order to improve the upper limit of the winning probability, so that the main game can be activated.

Further, for example, the selection unit 334 increases the winning probability so that the larger the number of messages sent by the player to the related player or the number of messages sent by the player to the main game to be solicited to the main game, the higher the upper limit of the winning probability. Set the upper limit of. As a result, each player sends more messages in order to improve the upper limit of the winning probability, so that it is possible to activate communication between the players.

Further, when the progress control unit 331 instructs the selection unit 334 to execute the lottery, the selection unit 334 specifies the player ID included in the lottery screen request, and reads out the lottery execution number associated with the specified player ID from the player table. .. Further, the selection unit 334 reads out the initial value of the winning probability of each group from the group table. The selection unit 334 calculates the winning probability of each group by the above method based on the read initial value and the number of lottery executions, and randomly selects the group according to the calculated winning probability. For example, the selection unit 334 randomly selects a group using a pseudo-random number generated by using the current clock counter value of the server 3 as a seed. Further, the selection unit 334 randomly selects a character card from each character card included in the selected group. For example, the selection unit 334 randomly selects a character card so that all the character cards are selected with the same probability by using a pseudo-random number generated by using the current clock counter value of the server 3 as a seed. ..

In this way, the selection unit 334 selects a character card from the plurality of character cards to be drawn, according to the request from the player. When a group other than the centerpiece card group is selected in the lottery, the selection unit 334 increments the number of lottery executions in the player table. In this case, the winning probability in the next lottery of the featured card is higher than the winning probability in the current lottery, and the winning probability in the next lottery of the character cards other than the featured card is lower than the winning probability in the current lottery. On the other hand, when the group of the centerpiece cards is selected in the lottery, the selection unit 334 resets the number of times the lottery is executed in the player table. In this case, the winning probability in the next lottery of each character card is reset and returns to the initial value.

Note that the selection unit 334 may not reset the number of times the lottery is executed and may not reset the winning probability of each character card in the next lottery even when the group of the centerpiece cards is selected in the lottery. As a result, the player can acquire another eyeball card with a high probability even after acquiring a specific eyeball card in the group of eyeball cards, and it is possible to improve the player's willingness to continue the lottery game. Will be.

Further, when the number of lottery executions reaches a predetermined number (for example, 50 times), the selection unit 334 may automatically reset the lottery execution number and reset the winning probability in the next lottery of each character card. As a result, each player needs to acquire the eyeball card during a predetermined number of times the lottery is executed, so that the game quality of the lottery game is improved and it is suppressed that a large number of eyeball cards are given to the player. ..

Further, the selection unit 334 may reset the number of lottery executions and reset the winning probability in the next lottery of each character card according to the request from the player.

Further, the selection unit 334 does not reset the winning probability of each character card when a special card is selected from among the featured cards, and when a card other than the special card is selected, the winning probability of each character card is selected. May be reset. In that case, since a large amount of special cards may be given to each player, it is preferable that a card that can be distributed in large quantities is defined as a special card. As a result, when a special card is selected, the winning probability of the featured card remains high, so that the game quality of the lottery game can be further improved. Alternatively, the special card may be set by each player for each player. As a result, the winning probability of the featured card remains high until the character card set by each player is selected, so that each player can surely acquire the desired card.

Next, the selection unit 334 instructs the association unit 335 to give the selected character card to the player. Next, the selection unit 334 calculates the winning probability of each group in the next lottery based on the number of lottery updates updated in the player table. The selection unit 334 creates display data for displaying the lottery result screen 420 showing the selected player card, the updated lottery execution number, and the calculated next winning probability, and passes the created display data to the progress control unit 331. ..

Further, when the progress control unit 331 instructs the selection unit 334 to create display data for displaying the detail screen 430, the selection unit 334 calculates the winning probability of each group for each lottery execution number of times, and calculates the lottery execution number of times. Display data for displaying the detail screen 430 showing the winning probability of the above is created, and the created display data is passed to the progress control unit 331.

When the selection unit 334 instructs the player to assign the character card, the association unit 335 grants the character card to the player by associating the character card selected by the selection unit 334 with the player and storing it. The association unit 335 assigns the character card to the player by adding the card ID of the character card to the card information owned by the player in the player table. At that time, the association unit 335 does not delete the character card selected by the selection unit 334 from the group table, but leaves it as a lottery target in the next lottery.

In this way, the association unit 335 leaves the selected character card as a lottery target in the next lottery regardless of whether a group other than the centerpiece card group is selected in the lottery or a centerpiece card group is selected. While giving to the player. As a result, even in the next lottery, the selection unit 334 will reselect the character card from the plurality of character cards set as the lottery target, including the character card of the same type as the given character card. .. That is, the type or number of character cards to be drawn in each lottery is not changed and is maintained.

FIG. 7 is a diagram showing an example of an operation sequence related to the lottery game processing of the game system 1. This operation sequence cooperates with each element of the mobile 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. Is executed.

First, when the player presses the lottery game button 402 using the operation unit 23 while the home screen 400 is displayed on the display unit 24 of the mobile terminal 2, the browsing execution unit 251 of the mobile terminal 2 requests the lottery screen. It is transmitted to the server 3 via the terminal communication unit 21 (step S101). When the progress control unit 331 of the server 3 receives the lottery screen request from the mobile terminal 2, the selection unit 334 wins each group in the next lottery based on the initial value of the winning probability of each group and the number of lottery executions of the player. Calculate the probability (step S102). Next, the selection unit 334 creates display data for displaying the lottery game screen 410 showing the number of times the player has executed the lottery and the calculated winning probability (step S103). Next, the progress control unit 331 transmits the display data created by the selection unit 334 to the mobile terminal 2 (step S104). 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 game screen 410 on the display unit 24. (Step S105).

Next, when the player presses the lottery button 413 using the operation unit 23 while the lottery game screen 410 is displayed on the display unit 24 of the mobile terminal 2, the browsing execution unit 251 of the mobile terminal 2 makes a lottery request. It is transmitted to the server 3 via the terminal communication unit 21 (step S106). When the progress control unit 331 of the server 3 receives the lottery request from the mobile terminal 2, the selection unit 334 executes the lottery process (step S107). The details of the lottery process will be described later. Next, the selection unit 334 creates display data for displaying the lottery result screen 420 showing the player card selected in the lottery process, the updated lottery execution number, and the calculated next winning probability (step S108). Next, the progress control unit 331 transmits the display data created by the selection unit 334 to the mobile terminal 2 (step S109). 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 420 on the display unit 24. (Step S110). This completes the operation sequence related to the lottery game process.

FIG. 8 is a diagram showing an example of an operation sequence related to the detailed screen display processing of the game system 1. This operation sequence cooperates with each element of the mobile 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. Is executed.

First, when the player presses the detail button 414 using the operation unit 23 while the lottery game screen 410 is displayed on the display unit 24 of the mobile terminal 2, the browsing execution unit 251 of the mobile terminal 2 requests the detail screen. It is transmitted to the server 3 via the terminal communication unit 21 (step S201). When the progress control unit 331 of the server 3 receives the detailed screen request from the mobile terminal 2, the selection unit 334 calculates the winning probability of each group for each lottery execution number (step S202). Next, the selection unit 334 creates display data for displaying the detailed screen 430 showing the winning probability for each calculated number of lottery executions (step S203). Next, the progress control unit 331 transmits the display data created by the selection unit 334 to the mobile terminal 2 (step S204). 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 causes the display unit 24 to display the detail screen 430. (Step S205). This completes the operation sequence related to the detailed screen display process.

FIG. 9 shows an operation flow of the lottery process by the selection unit 334 and the association unit 335. The home screen display data creation process shown in FIG. 9 is executed in step S107 of FIG.

First, the selection unit 334 calculates the winning probability of each group in the current lottery based on the number of times the lottery is executed by the player (step S301). Next, the selection unit 334 randomly selects a group according to the calculated winning probability, and randomly selects a character card from each character card included in the selected group (step S302). Next, the selection unit 334 determines whether or not the eyeball card has been selected in the lottery (step S303). When a character card other than the eyeball card is selected in the lottery (step S303-No), the selection unit 334 increments the number of lottery executions associated with the player in the player table (step S304). On the other hand, when the eyeball card is selected in the lottery (step S303-Yes), the selection unit 334 resets the number of lottery executions associated with the player in the player table (step S305).

Next, the association unit 335 grants the character card selected by the selection unit 334 to the player by adding the character card selected by the selection unit 334 to the possessed card information of the player table without deleting it from the group table (step S306). End the step of.

The selection unit 334 may execute the lottery using the winning probability calculated in step S102 of FIG. 7 instead of calculating the winning probability of each group in the current lottery in step S301.

As described above, the server 3 can flexibly change the winning probability of the eyeball card according to the number of lottery executions, so that it is possible to improve the player's expectation for the acquisition of the eyeball card. Become. Further, the player can increase the winning probability of the featured card by repeating the lottery game, so that he / she can get a feeling of nurturing the lottery game.

Further, in the lottery of the present embodiment, the winning character card is not deleted from the lottery target, so that the player can acquire the winning character card again. Therefore, in a game in which the same card can be used to raise the level or the upper limit of the level of the character card, the player is likely to raise the level or the upper limit of the level of the character card.

Further, in the lottery in which the winning character card is deleted from the lottery target, the winning probability of all the remaining cards increases, whereas in the lottery of the present embodiment, the larger the number of lottery executions, the higher the number of featured cards. The winning probability is high, and the winning probability of other cards is low. Therefore, in the lottery of the present embodiment, the more the lottery is repeated, the lower the possibility that the unwinned card will be won, and the lower the possibility that the card that the player does not need will be won.

The present invention is not limited to the present embodiment. For example, in the present embodiment, the centerpiece card is predetermined by the operator of the game system, but some or all of the character cards included in the centerpiece card group are from the player using the mobile terminal 2. It may be set according to the request. As a result, each player can increase the winning probability of the character card he / she wants each time he / she executes the lottery, and can further improve the player's willingness to continue the lottery.

Further, the selection unit 334 may change the winning probability so that only the winning probability of the character card selected in the lottery becomes low and only the winning probability of the featured card becomes high. Alternatively, the selection unit 334 may change the winning probability so that only the winning probability of the character card selected in the lottery is low and the winning probability of all the other character cards is high. As a result, it is possible to reduce the possibility that the same character card will be won more than once, so that the game property in the lottery game can be reduced while reducing the possibility that the player will be disappointed by obtaining the same character card. Can be maintained.

On the contrary, the selection unit 334 may change the winning probability so that only the winning probability of the character card other than the eyeball card, which is not selected in the lottery, becomes low and only the winning probability of the eyeball card becomes high. .. Alternatively, the selection unit 334 may change the winning probability so that only the winning probability of the character card other than the eyeball card that was not selected in the lottery is low and the winning probability of all the other character cards is high. .. In a game in which the upper limit of the parameter value of the character card can be increased by using the same character card, the probability of acquiring the same character card can be maintained or improved, and the upper limit can be increased. It is possible to maintain or improve the possibility of being able to do so.

Further, the main game execution unit 333 may give a privilege to the player in the main game when the number of lottery executions reaches the upper limit or a predetermined number in the lottery game. For example, the main game execution unit 333 grants the player a game medium such as an item or a character card used in the main game as a privilege. Alternatively, the main game execution unit 333 may, as a privilege, make the game points given to the player in the main game larger than the points normally given. As a result, each player executes the lottery game more frequently so that the main game can be advanced more advantageously, so that the whole game can be activated.

Further, when the lottery game is executed every predetermined event period, the server 3 when the number of lottery executions (probability of winning the centerpiece card) reaches the upper limit or the predetermined value in the lottery game executed in the specific event period. May take over the number of times the lottery is executed (probability of winning the centerpiece card) to the lottery game to be carried out during the next event period. In that case, the server 3 does not delete the number of lottery executions (probability of winning the eyeball card) even after the end of the specific event period, and the number of times of lottery execution (probability of winning the eyeball card) in the lottery to be executed in the next event period. ) Is used as the initial value. As a result, each player executes the lottery game more frequently in anticipation of the merits obtained in the future, so that the lottery game can be activated.

Further, in the present embodiment, another game different from the main game has been described as a lottery game, but the game is not limited to the lottery game, and any form of game can be used as long as it is a game that selects a specific game medium. May be.

Further, in the present embodiment, an example in which the selected game medium is given to the player has been described, but the selected game medium may not necessarily be given to the player as long as it is stored in association with the player. For example, the selected game medium may be set so that the player can only view it 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 group table are stored in the terminal storage unit 22, it is not necessary to communicate with the server 3 each time the processing is performed, and the above function can be realized only by the mobile terminal 2. Is. Further, the game executed on the mobile terminal 2 may be a hybrid game in which the server 3 and the mobile terminal 2 each play a part of the processing. In that case, for example, each screen related to the progress of the game is 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 native applications installed on the mobile terminal 2. The native display is displayed by.

It will be appreciated by those skilled in the art that various changes, substitutions and modifications can be made to this without departing from the spirit and scope of the invention.
