Description

  The present invention relates to an information processing technique for controlling execution of a game having a function of selecting an object to be given to a user by lottery from a plurality of objects included in a box for each user.

  In recent years, so-called social games have become widespread as applications executed in social networking services (SNS). As such a social game, a box including a plurality of cards is prepared for each user, a plurality of cards included in the box are used as a population, and a card to be given to the user is selected by lottery (hereinafter referred to as “box” A game having a “lottery function” is known. For example, there is a game of Patent Document 1 as a game having a box lottery function. In Patent Document 1, the card to be given to the user is deleted from the box after being given to the user.

Japanese Patent No. 5335969

However, just deleting a card given to a user from the box as in Patent Document 1 does not significantly increase the probability that a specific card is given to the user in the next box lottery process.
For example, consider a case where one box with a high rare value and 99 cards with a low value are included in a box. In this case, the probability that a card having a high rare value is given to the user by the first box lottery is 1/100. If a single low-value card is given to the user by the first box lottery, the probability that a high-value card is given to the user by the second box lottery is 1/99. In other words, although the probability that a specific card is given to the user increases as the number of cards constituting the population corresponding to the denominator of the probability (that is, the remaining number of cards included in the box) decreases, Since the remaining number of cards contained in a box is reduced by the number of cards given to the user by one box lottery, the probability that a specific card will be given to the user in the next box lottery process greatly increases Never do.
In general, a box with a box lottery function is configured so that the number of cards having a higher rare value is smaller. Therefore, the greater the number of remaining cards in the box, the lower the probability that a rare value card will be awarded in the box lottery function. This is a factor that attenuates the motivation for the user to use the box lottery function. In addition, even for users who have used the box lottery function, the motivation to repeatedly use the box lottery function is a factor that attenuates. In particular, in a game in which the box lottery function is provided for a fee, the motivation for the user to use the box lottery function is greatly attenuated.

(1-4) Box lottery process of game of this embodiment The game executed in the game system 1 of this embodiment is a game using cards as objects. In this game, for example, a card held by the user is used to play against another user or NPC (Non-Player Character). The object is not limited to a card, and any object can be used as long as it can be used in a game.
The process executed in the game of the present embodiment includes a box lottery process.
The box lottery process gives a user a card selected from a plurality of cards included in a box associated with each user (that is, a population for each user), a card given to the user, In this process, a card selected from cards other than the card (that is, a card not given to the user) is deleted from the box.

The box lottery process of the present embodiment will be specifically described with reference to FIG. FIG. 4 is a diagram for conceptually explaining the box lottery process of the present embodiment.
In the example of FIG. 4, the possession card O1 and the box B1 are associated with the user U1. Before the box lottery process is executed, the card A is a possessed card, and the cards B to E are included in the box B1.
First, the card B is selected by lottery from the cards included in the box as a card to be given to the user U1 and deleted from the box B1. The selected card B is given to the user U1 as a possessed card O1, and is deleted from the box B1. Next, the card C is selected as a card to be deleted from the box B1 without being given to the user U1 from cards other than the card B among the cards included in the box B1. The selected card C is deleted from the box B1 without being associated with the user U1 as the possessed card O1.
In other words, in the box lottery process of this embodiment, not only the card B given to the user U1, but also the card C not given to the user U1 is deleted from the box B1. This greatly increases the probability that a specific card will be given in the next box lottery process. Accordingly, the user U1 is given a sense of expectation that the card may be given in the next box lottery process even if the specific card is not given in one box lottery process. Thereby, the motivation of utilizing a box lottery function can be given to a user. In particular, a user who has used the box lottery function can be motivated to use the box lottery function repeatedly.

Next, the game server 20 transmits the display information to the user terminal 10 via the communication interface unit 24.
The CPU 11 of the user terminal 10 presents the execution result to the user by displaying a screen based on the display information transmitted from the game server 20 on the display unit 16.

  The game processing unit 52 has a function of executing various game processes in response to a user request developed in the RAM 23 by the receiving unit 51. The game process of the present embodiment may be provided as appropriate, and is, for example, a composition process.

The function of the game processing means 52 for executing the synthesis process is realized as follows.
The CPU 21 of the game server 20 reads the possessed card data corresponding to the user ID included in the request for the synthesis process developed in the RAM 23 by the accepting means 51 from the possessed card data table and develops it in the RAM 23. Next, the CPU 21 specifies the serial number of the card to be selected as the base card and the serial number of the card to be selected as the reference card based on the user instruction from the serial numbers included in the possessed card data. . Next, the CPU 21 determines a value after an increase in the card level of the base card based on the card data of the reference card. Next, the CPU 21 generates display information (for example, HTML) that is a basis of a screen that presents the execution result of the synthesis process, and transmits the display information to the user terminal 10.
The CPU 11 of the user terminal 10 displays a screen based on the display information transmitted from the game server 20 on the display unit 16, thereby presenting the execution result of the synthesis process to the user.

(1-8) Game Process Flow of the Present Embodiment Next, an example of the game process flow of the present embodiment will be described with reference to FIGS. 11A and 11B.
11A and 11B are sequence charts showing a box lottery process according to the present embodiment. In FIG. 11A and FIG. 11B, the step of displaying each screen shown in FIG.

  11A, when a user designates a predetermined button (for example, button b3 (“box lottery” on screen P1 in FIG. 9)) on the screen displayed on user terminal 10, CPU 11 of user terminal 10 causes box lottery to be performed. Is received (S10), and the request is transmitted to the game server 20 (S11).

CPU21 of the game server 20 will read card data, possession card data, and box data from the storage 25, if the request transmitted by S11 is received (S12).
Specifically, the CPU 21 reads all the card data from the card data table, and performs possession card data corresponding to the user ID included in the request (that is, a request for box lottery processing) from the possession card data table. The user possessed card data) is read out, and the box data corresponding to the user ID (that is, information on the box of the user who requested the box lottery process) is read out from the box data table.

  Next, the CPU 21 of the game server 20 generates display information (for example, HTML) that serves as a basis for a screen that presents information on the candidate card to the user based on the box data read in S12 (S13). Here, as shown in the screen P2 of FIG. 9, the CPU 21 generates display information so that the screen is displayed in a manner in which the grant candidate cards can be distinguished for each rarity.

  Next, the CPU 21 of the game server 20 transmits the display information to the user terminal 10 (S14).

  When the CPU 11 of the user terminal 10 receives the display information transmitted in S14, the CPU 11 generates a screen (screen P2 in FIG. 9) for presenting the information on the candidate card to the user based on the display information. Based on the designation of the user with respect to the designation target included (button b4 (“granting lottery” in FIG. 9)), an instruction for granting lottery is accepted (S15) and the instruction is transmitted to the game server 20 (S16).

  When the CPU 21 of the game server 20 receives the instruction transmitted in S16, it selects at least one card ID by lottery from the card IDs of the accommodation cards included in the box data read in S12 based on the instruction. (S17). A card to be given to the user and deleted from the box is specified by the card ID.

  Next, the CPU 21 of the game server 20 adds the card ID selected in S17, the card parameters (for example, the card level and skill level) corresponding to the card ID, the new serial number, to the possessed card data read in S12. Is recorded in association with each other, the possessed card data table is updated (S18), and display information (for example, a screen for presenting that the card corresponding to the card ID selected in S17 is given to the user (for example, HTML) is generated (S19), and the display information is transmitted to the user terminal 10 (S20).

  Upon receiving the display information transmitted in S20, the CPU 11 of the user terminal 10 displays a screen (FIG. 9) indicating that the card selected from the grant candidate cards has been granted to the user based on the display information. Screen P3) is generated, and a deletion lottery instruction is accepted based on the user's designation for the designation target (button b6 (“deletion lottery” in FIG. 9)) included in the screen (S21). 20 (S22).

  When the CPU 21 of the game server 20 receives the instruction transmitted in S22, based on the instruction, the CPU 21 selects at least one card ID from the card IDs of the accommodation cards included in the box data read in S12 ( S23). A deletion candidate card is specified by the card ID.

  Next, the CPU 21 of the game server 20 generates display information (for example, HTML) that is a basis of a screen for presenting information on the deletion candidate card corresponding to the card ID selected in S23 to the user (S24). Is transmitted to the user terminal 10 (S25).

  When the CPU 11 of the user terminal 10 receives the display information transmitted in S25, the CPU 11 generates a screen (screen P4 in FIG. 9) that accepts designation of a card to be deleted from the deletion candidate card based on the display information. Then, based on the user's specification for the check box and the button b7 ("selection delete") or the button b8 ("delete all") included in the screen, the specification of the card to be deleted from the box is accepted (S26) and specified. The card ID of the received card is transmitted to the game server 20 (S27). The card to be deleted from the box is specified by the card ID.

  When receiving the card ID transmitted in S27, the CPU 21 of the game server 20 cancels the association between the card ID selected in S17 and the card ID transmitted in S27 with the box ID of the box data read out in S12. Thus, the box data table is updated (S28).

  Next, the CPU 21 of the game server 20 displays display information (for example, HTML, for example) that presents the information of the card whose association with the box ID has been canceled in S28 (that is, the card deleted from the box) to the user. ) Is generated (S29), and the display information is transmitted to the user terminal 10 (S30).

  When the CPU 11 of the user terminal 10 receives the display information transmitted in S30, the CPU 11 generates a screen (screen P5 in FIG. 9) that presents the card information deleted from the box to the user based on the display information. It displays on the display part 16 (S31).

  As described above, by executing the box lottery process according to the present embodiment, in addition to the cards given to the user, the cards not given to the user are also deleted from the box. Therefore, even if a card with high rarity is not given in one box lottery process, the probability that the card is given in the next box lottery process greatly increases.

For example, consider the probability p (n) that a card with a rarity R5 is awarded in the nth (n is an integer greater than or equal to 1) box lottery process under the following conditions.
・ Remaining number of accommodations before execution of n-th box drawing process: 100
・ Remaining number of R5 cards with R5 before the n-th box drawing process is executed: 3
-Number of cards given to the user in one box lottery process: 1
-Number of cards deleted from the box without being given to the user in one box lottery process: 10
In this case, the probability that the card with the rarity R5 is given in the n-th box lottery process is p (n) = 3/100.
Here, when only the card to be given to the user is deleted from the box as in the past, the probability that the card with the rarity R5 is given in the (n + 1) th box lottery process is p (n + 1) = 3/99. It is.
On the other hand, in the case where, in addition to the card to be given to the user as well as the card not to be given to the user is deleted from the box as in the present embodiment, the probability that the card with the rarity R5 is given in the (n + 1) th box drawing process , P (n + 1) = 3/89.

  As described above, according to the present embodiment, even if a specific card is not given in one box lottery process, the probability that the card is given in the next box lottery process greatly increases. Therefore, the user is given a sense of expectation that a specific card may be awarded in the next box lottery process. Thereby, the motivation of utilizing a box lottery function can be given to a user. In particular, a user who has used the box lottery function can be motivated to use the box lottery function repeatedly.

  In this embodiment, since the information of the card deleted from the box is presented in S31, the user is made aware of which card has been deleted from the box (that is, whether or not a specific card remains in the box). be able to.

  Moreover, in this embodiment, since the information of the card | curd provided to the user in S21 is shown to a user, in S31, since the information of the card deleted from the box is shown to a user, which card was given, It is possible to make the user more aware of which card has been deleted from the box (that is, whether a specific card remains in the box).

  In the present embodiment, since the designation of the card to be deleted from the box is accepted from the user in S26, the user is made to think about a game strategy of which card to delete from the box is advantageous for the progress of the game. be able to. Thereby, the preference of a box lottery function can be improved.

(1-9) Modified Example of Embodiment Hereinafter, a modified example of the present embodiment will be described. The following modifications can be combined with each other.

(1-9-1) First Modification A card to be selected as a deletion candidate card in S23 may be selected based on card data.
As an example, in S23, the CPU 21 of the game server 20 refers to the rarity of the card data corresponding to the card ID included in the box data, and selects at least one card ID corresponding to a predetermined or lower (for example, R1) rarity. May be. According to this example, since a card with low rarity is deleted from the box, the probability that a card with high rarity is given can be increased.
As another example, in S23, the CPU 21 of the game server 20 may refer to the card ID included in the possessed card data and select at least one card ID identical to the card ID. According to this example, since the card already possessed by the user is deleted from the box, it is possible to increase the probability that a card not possessed by the user is given. This example is particularly effective in a game in which an effect (for example, an item) that is advantageous for the progress of the game is given as the number of possessed cards increases.
As another example, in S23, the CPU 21 of the game server 20 may refer to the card ID included in the possessed card data and select at least one card ID different from the card ID. According to this example, since a card different from the card already possessed by the user is deleted from the box, the probability that the same card as the card possessed by the user is given can be increased. This example is particularly effective in a game in which an advantageous effect (for example, a card having a higher rarity than a synthesized card) can be obtained by synthesizing the same cards.

(1-9-2) Second Modification The number of cards to be selected as deletion candidate cards in S23 may be determined based on the number of cards included in the box.
As an example, in S23, the CPU 21 of the game server 20 refers to the value of the remaining accommodation number included in the box data. Next, when the value is equal to or greater than a predetermined value (for example, half of the total number accommodated), the CPU 21 selects two cards as deletion candidate cards. On the other hand, when the value is less than the predetermined value, the CPU 21 selects one card (that is, fewer cards than when the value is greater than or equal to the predetermined value) as the deletion candidate card. In other words, the larger the remaining number of boxes accommodated (that is, the lower the probability that a specific card will be given), the more other cards are deleted from the box.
According to this example, the greater the remaining number of boxes accommodated (that is, the smaller the number of executions of the box lottery process), the greater the increase in the probability that a specific card will be awarded. Thereby, the motivation to repeatedly use the box lottery function can be given to the user who uses the box lottery function less frequently. In particular, in social games, users who use less functions of the game tend to give up continuation of the game, so users who use the box lottery function frequently use the box lottery function repeatedly. Is extremely effective in allowing the user to continue playing the game.

(1-9-3) Third Modification In the box data table, the total number of accommodations and the number of remaining accommodations for each card parameter may be recorded in association with each pair of box ID and user ID.
As an example, FIG. 12 shows a configuration example of a box data table of this modification.
In the box data table shown in FIG. 12, for each pair of box ID and user ID, data on the total number of accommodation and the total number of accommodation for each of the rarities R1 to R5 of the accommodation card is recorded in association with each other.
The total number of accommodation is a fixed value indicating the maximum number of cards of each rarity included in the box. Further, the total number of accommodations may be a common value for all rarities, or may be a value different for each rarity.
The remaining number is a variation value indicating the remaining number of cards of each rarity included in the box. Each time a card is deleted from the box, the value of the remaining storage number decreases by the number of cards to be deleted. When the value of the remaining number of remaining rarities becomes zero, the association between the box ID and the user ID is cancelled.
FIG. 13 shows a change in the display screen of the box lottery process of this modification. In FIG. 13, the screen P2-1 is the first implementation in that, instead of the information on the card included in the box, the value of the remaining capacity for each of the rarities R1 to R5 is displayed in the display area 101-1. This is different from the form display screen (screen P2 in FIG. 8).
In this example, the user can grasp the remaining number of cards included in the box and the probability that the card is given for each rarity. Therefore, the user can realize that the probability that a card with high rarity is given has increased by repeatedly using the box lottery function. Thereby, a motivation to repeatedly use the box lottery function can be given to the user.

(1-9-4) Fourth Modification The box data table may be a combination of the first embodiment (FIG. 8) and the third modification (FIG. 12). According to this box data table, the card specified by the card ID and the card specified by the remaining number for each rarity are included in the box.
As an example, for a card with a high rarity (rareity: R5), a card ID is recorded in association with each pair of a box ID and a user ID as shown in FIG. Regarding (rarety: R1 to R4), as shown in FIG. 12, the total number of accommodations and the number of remaining accommodations for each pair of box ID and user ID are recorded in association with each other.

(2) Second Embodiment In the first embodiment, the example of presenting the card information to be given to the user has been described. However, in the second embodiment, the card is given to the user before the information is presented. An example of presenting information on a card that may be displayed will be described.
Note that the hardware configuration of this embodiment may be the same as that of the first embodiment. The game of this embodiment may be the same as the game of the first embodiment.

(2-1) Game Box Lottery Processing of the Present Embodiment The box lottery processing of the present embodiment will be specifically described with reference to FIG. FIG. 14 is a diagram for conceptually explaining the box lottery process of the present embodiment.
In the example of FIG. 14, a plurality of grant candidate cards are selected from a plurality of cards included in the box B1, information on the grant candidate cards is presented to the user U1, and given to the user U1 from the grant candidate cards. This is different from the box lottery process (FIG. 4) of the first embodiment in that the card to be selected is selected, the selected card is given to the user U1, and the grant candidate card is deleted from the box B1.
First, from the cards included in the box B1, cards B to D are selected by lottery as grant candidate cards. Next, information on the grant candidate card is presented to the user U1. Next, a card (for example, card B) to be given to the user U1 is selected by lottery from the grant candidate cards. The selected card B is given to the user U1 as the possessed card O1. Next, the grant candidate card is deleted from the box B1 associated with the user U1.
In other words, in the box lottery process of the present embodiment, the information on the grant candidate card is displayed after the selection of the grant candidate card (card B to card D) until the card to be given to the user U1 is determined. Presented to. That is, information on cards that may be given in the box lottery process is presented to the user U1 before the card given to the user U1 is confirmed. Therefore, the user U1 experiences two lotteries (lottery of grant candidate cards and lottery of cards to be given to the user) in one box lottery process. Thereby, the preference of a box lottery function can be improved.
Further, in the box lottery process of the present embodiment, the card C and the card D that are not given to the user U1 are deleted from the box B1 in addition to the card B that is given to the user U1 as in the first embodiment. This greatly increases the probability that a specific card will be given in the next box lottery process. Accordingly, the user U1 is given a sense of expectation that the card may be given in the next box lottery process even if the specific card is not given in one box lottery process.
Thereby, the motivation to repeatedly use the box lottery function can be given to the user.

(2-2) Specific example of box lottery processing (FIG. 15)
Hereinafter, a specific example of the game processing of the present embodiment will be described with reference to FIG. FIG. 15 is a diagram illustrating an example of a screen displayed on the user terminal 10 when executing the game process of the present embodiment.
FIG. 15 shows a change in a series of display screens in the box lottery process. 15, the screen P2-2 is different from the button b4 (“grant lottery”) in FIG. 9 in that a button b4-2 (“candidate lottery”) is provided in the first embodiment (FIG. 9). It is different from the screen P2).
The button b4-2 is a button that is designated when an instruction is given to select a plurality of candidate cards including both a card that is given to the user and deleted from the box and a card that is not given to the user and is deleted from the box. It is.

When the button b4-2 (“candidate lottery”) is designated on the screen P2-2, the screen changes as shown in P6. The screen P6 is a screen for presenting information on the card selected as the candidate card by the candidate lottery.
On the screen P6, a display area 107 and a button b9 (“grant lottery”) are provided.
In the display area 107, information (card name and rarity) of the card selected as the candidate card and a message indicating that the grant candidate card has been determined are displayed.
The button b9 is a button that is designated when an instruction is given to select a card to be given to the user from among a plurality of grant candidate cards.

When the button b9 (“grant lottery”) is designated on the screen P6, the screen changes as shown in P3-2. The screen P3-2 is a screen that presents that at least one of the grant candidate cards has been granted to the user.
On the screen P3-2, the button b6 (“delete lottery”) is not an instruction to select a card to be deleted from the box without giving the user, but an instruction to advance the box lottery process without selecting the card. This is different from the first embodiment (screen P3 in FIG. 9) in that it is a button specified when performing.

  When the button b6 (“delete lottery”) is designated on the screen P3-2, the screen changes as shown in P5 of FIG. 9 as in the first embodiment.

(2-3) Overview of Functions Provided by Information Processing Device Next, functions provided by the game server 20 in order to realize the game of the present embodiment will be described. FIG. 16 is a functional block diagram for explaining functions that play major roles in the game server 20 of the present embodiment. In FIG. 16, the receiving means 51 and the game processing means 52 are the same as those in the first embodiment (FIG. 10). Note that not all the means included in the functional block diagram shown in FIG. 16 are indispensable elements for the present invention. For example, in one aspect of the present invention, the third selection unit 57, the fourth selection unit 58, the second update unit 59, and the second output unit 60 may be provided.

The third selection means 57 has a function of selecting a plurality of grant candidate cards from a plurality of cards included in the box.
The function of the 3rd selection means 57 is implement | achieved as follows. The CPU 21 of the game server 20 reads out box data corresponding to the user ID included in the box lottery processing request developed in the RAM 23 by the accepting means 51 from the box data table based on the user's instruction, and develops it in the RAM 23. To do. Next, the CPU 21 selects a plurality of card IDs by lottery from the card IDs of the accommodation cards included in the box data. The grant candidate card is specified by the card ID selected by the third selection means 57.

The fourth selection means 58 has a function of selecting a card to be given to the user from among a plurality of grant candidate cards.
The function of the 4th selection means 58 is implement | achieved as follows. The CPU 21 of the game server 20 selects at least one card ID from among a plurality of card IDs selected by the third selection means 57 by lottery. The card to be given to the user and deleted from the box is specified by the card ID selected by the fourth selection means 58.

The second updating unit 59 includes a first function for giving a user a card corresponding to the card ID selected by the fourth selection unit 58, and a card (granting candidate) corresponding to the card ID selected by the third selection unit 57. A second function of deleting the card) from the box.
The first function of the second update means 59 is realized as follows. The CPU 21 of the game server 20 is selected by the fourth selection means 58 from the possession card data table to possession card data corresponding to the user ID included in the box lottery process request developed in the RAM 23 by the acceptance means 51. A card ID, a card level corresponding to the card ID (for example, initial value 1), a skill level corresponding to the card ID (for example, initial value 1), and a new serial number are recorded in association with each other. Then, the possessed card data table is updated.
The second function of the second update means 59 is realized as follows. The CPU 21 updates the box data table by canceling the association between the box ID and the user ID of the box data expanded in the RAM 23 by the third selection unit 57.

The second output means 60 has a first function for presenting information on the candidate card to the user before the card to be given to the user is confirmed, a second function for presenting the card information given to the user to the user, And a third function for presenting to the user that the grant candidate card has been deleted from the box.
The first function of the second output means 60 is realized as follows. The CPU 21 of the game server 20 reads card data corresponding to a plurality of card IDs selected by the third selection means 57 from the card data table and develops them in the RAM 23. Next, based on the card data, the CPU 21 generates display information (for example, HTML) that is a basis of a screen that presents information on the candidate card for grant. Next, the game server 20 transmits the display information to the user terminal 10 via the communication interface unit 24. The CPU 11 of the user terminal 10 presents information on the grant candidate card to the user by displaying a screen based on the display information transmitted from the game server 20 on the display unit 16.
The second function and the third function of the second output means 60 are each realized as follows. CPU21 produces | generates the display information (for example, HTML) used as the basis of the screen which shows the execution result of the process by the 1st function of the 2nd update means 59, and a 2nd function, respectively. Next, the game server 20 transmits the display information to the user terminal 10 via the communication interface unit 24. The CPU 11 presents the execution result to the user by displaying a screen based on the display information transmitted from the game server 20 on the display unit 16.

(2-4) Game Processing Flow of this Embodiment Next, an example of the game processing flow of this embodiment will be described with reference to FIGS. 17A and 17B.
FIG. 17A and FIG. 17B are sequence charts showing the box lottery process of the present embodiment. In FIGS. 17A and 17B, the step of displaying each screen shown in FIG. In FIG. 17A and FIG. 17B, the same reference numerals as those in FIG. 11A and FIG. 11B are assigned to the processing steps common to the first embodiment.

  Similarly to the first embodiment (FIG. 11A), after S11 to S14 are finished, when the CPU 11 of the user terminal 10 receives the display information transmitted in S14, the CPU 11 of the grant candidate card is based on the display information. A screen for presenting information to the user (screen P2-2 in FIG. 15) is generated, and based on the user's designation for the designation target (button b4-2 (“candidate lottery” in FIG. 15)) included in the screen, A candidate lottery instruction is accepted (S40), and the instruction is transmitted to the game server 20 (S41).

  When the CPU 21 of the game server 20 receives the instruction transmitted in S41, based on the instruction, the CPU 21 selects a plurality of card IDs by lottery from the card IDs of the accommodation cards included in the box data read in S12. (S42). The card ID is the card ID of the grant candidate card.

  Next, the CPU 21 of the game server 20 generates display information (for example, HTML) that serves as a basis for a screen that presents information on the card (granting candidate card) corresponding to the card ID selected in S42 (S43), and displays the display. Information is transmitted to the user terminal 10 (S44).

  Next, when the CPU 11 of the user terminal 10 receives the display information transmitted in S44, the CPU 11 generates a screen (screen P6 in FIG. 15) for presenting information on the grant candidate card based on the display information. Based on the designation of the user with respect to the designation target included (button b9 (“granting lottery”) in FIG. 15), a granting lottery instruction is accepted (S45), and the instruction is transmitted to the game server 20 (S46).

  When receiving the instruction transmitted in S46, the CPU 21 of the game server 20 selects at least one card ID by lottery from the plurality of card IDs selected in S42 based on the instruction (S47). As in the first embodiment, the possessed card data table is updated (S18), display information (for example, HTML) is generated (S19), and the display information is transmitted to the user terminal 10 (S20).

  When the CPU 11 of the user terminal 10 receives the display information transmitted in S20, a screen (screen P3-2 in FIG. 15) presenting that at least one of the grant candidate cards has been granted to the user based on the display information. ) And receives a deletion lottery instruction based on the user's designation for the designation target (button b6-2 ("next") in FIG. 15) included in the screen (S48), and the instruction is sent to the game server. 20 (S49).

  When receiving the instruction transmitted in S49, the CPU 21 of the game server 20 updates the box data table by canceling the association between the card ID selected in S42 and the box ID of the box data read out in S12. (S50), similarly to the first embodiment, display information (for example, HTML) that is a basis of a screen for presenting information of the card deleted from the box to the user is generated (S29), and the display information is converted to the user. It transmits to the terminal 10 (S30).

  When receiving the display information transmitted in S30, the CPU 11 of the user terminal 10 generates a screen (screen P5 in FIG. 9) that presents the information of the card deleted from the box to the user, as in the first embodiment. Is displayed on the display unit 16 (S31).

  As described above, by executing the box lottery process of the present embodiment, the card information that may be given in the box lottery process is displayed to the user before the card given to the user is confirmed. Present. Therefore, the user will experience two lotteries (lottery of grant candidate cards and lottery of cards to be given to the user) in one box lottery process. Thereby, the preference of a box lottery function can be improved.

  Moreover, by executing the box lottery process of the present embodiment, in addition to the cards to be given to the user, the cards not to be given to the user are also deleted from the box, as in the first embodiment. Therefore, even if a specific card (for example, the rarity is R5) is not given in one box lottery process, the probability that the card is given in the next box lottery process greatly increases.

(3) Third Embodiment In the above-described embodiment, communication according to HTTP is performed between the user terminal 10 and the game server 20, and the user terminal 10 interprets an HTML document acquired from the game server 20. The case where the game is realized by the so-called browser format in which the game image is displayed has been described, but the present invention is not limited to this. In the game of the present embodiment, the user terminal 10 executes the game process by executing the game program downloaded by the user terminal 10, and the transmission / reception process between the user terminal 10 and the game server 20 is suppressed. You may implement | achieve by what is called a native application format. In the native application format, the CPU 11 of the user terminal 10 generates image data without using a web browser, thereby displaying a screen on the display unit 16.
In the present embodiment, an example in which the game of the above-described embodiment is realized in the native application format will be described. Note that the hardware configuration of this embodiment may be the same as that of the first embodiment. In the format of the native application of the present embodiment, it is assumed that most of the processing is performed on the user terminal 10 side. The processing may be executed on the server 20 side and the processing result by the game server 20 may be transmitted to the user terminal 10.

In the present embodiment, the user terminal 10 receives a game program from the game operator's server based on a user instruction, and the received game program is stored in the storage 18. When the game program is activated by the user terminal 10, communication is established between the user terminal 10 and the game server 20, a login process for logging in to the game is performed, and the data table is transferred from the game server 20 to the user terminal 10. Groups (card data table, user data table, possessed card data table, and box data table) are transmitted. The data table group is stored in the storage 18 of the user terminal 10. The data table group stored in the storage 18 is updated each time the login process is performed.
In order to prevent the possession card data table and the box data table from being falsified in the user terminal 10, every time a predetermined process by the user terminal 10 is completed, or when a logout process for logging out from the game is performed, The possessed card data table and the box data table stored in the storage 18 are transmitted to the game server 20. In the game server 20, the possessed card data table and the box data table received from the user terminal 10 are respectively compared with the possessed card data table and the box data table stored in the storage 25, and the data is not falsified. After confirming, the possessed card data table and the box data table stored in the storage 25 are respectively updated based on the possessed card data table and the box data table received from the user terminal 10.

  In the above-described embodiment, the designation input to the user terminal 10 is an input of a predetermined button press operation on the user terminal or a touch operation input on the display screen for the user terminal having a touch panel function. The input is not limited to this. The designation input may be an input by shaking a user terminal equipped with an acceleration sensor, or an input by a gesture (gesture input). In gesture input, by performing a predetermined gesture for a user terminal having an imaging function, the user terminal recognizes an image of the gesture and recognizes an operation input associated with the gesture in advance. In the case of a user terminal capable of executing a voice recognition program, the designation input may be performed by voice input.

[Summary of Invention]
From the above description, the present invention is grasped as follows, for example.

One embodiment of the present invention provides:
An information processing apparatus for assigning an object to a user, a storage device (25) that is a population associated with the user and stores population information for specifying a population associated with a plurality of objects In an information processing apparatus accessible to
From among objects associated with the population specified by the population information stored in the storage device (25), an object to be given to the user and to cancel the association with the population is selected by lottery. First selecting means (53) to perform,
Second selecting means (54) for selecting a predetermined number of objects to be released from the association with the population without giving to the user from the objects associated with the population;
The association between the object selected by the first selection means (53) and the population and the association between at least one of the objects selected by the second selection means (54) and the population are released. First updating means (55) for updating the population information,
Is an information processing apparatus.

The “information processing apparatus” may be a stand-alone game machine, a user terminal (for example, a portable terminal or a personal computer), a network server, or the like. The entity of the information processing apparatus can be appropriately defined depending on the game implementation form. For example, when the function of each part of the information processing apparatus is realized by the user operating the game machine or the user terminal, the game machine or the user terminal corresponds to the information processing apparatus of the present invention. Alternatively, when a user terminal that is a client has a function of accepting an operation input by a user and a function of displaying an image, and the function of each unit of the information processing apparatus is realized by a server that can substantially communicate with the user terminal The server corresponds to the information processing apparatus of the present invention.
The “storage device” may be a memory device having any configuration, such as a flash memory or an HDD (Hard Disk Drive). Further, the “storage device” may be a device built in the information processing device, or may be an external device configured to be accessible from the information processing device in a wired or wireless manner.
The “object” may be a game medium (for example, a card or an item) used in a game performed in a virtual space, or a game medium (for example, a lottery product) used in a game performed in a real space. There may be.
The “population information” may specify a population based on information on objects included in the box (for example, information specifying the object), or may specify a population based on the number of objects included in the box. Or a combination thereof.
The “first selection means” may select objects at random or may select objects in a predetermined order. That is, the “lottery” may be any process as long as it is a process of selecting an object to be given to the user from a plurality of objects in a manner in which the user does not know which object is selected.
The “second selection unit” may select a predetermined number of objects based on a predetermined algorithm, or may select a predetermined number of objects at random.

In order for the user to continue playing the game, it is important to give the user a sense of expectation for the game. In order to give the user a sense of expectation for the game, it is effective to allow the user to repeatedly use the functions of the game. However, when the probability that a specific card is given in a single box lottery process is low, the user gives an impression that it is difficult to obtain the card using the box lottery function. The box lottery function is not used, which leads to giving up the user to continue playing the game.
In the information processing apparatus, in the box lottery process, in addition to the card that is given to the user, the card that is not given to the user is also deleted from the box. Therefore, even if a specific card is not given in one box lottery process In the next box lottery process, the probability that the card will be awarded is greatly increased. Therefore, the user is given a sense of expectation that a specific card may be awarded in the next box lottery process. Thereby, the motivation to repeatedly use the box lottery function can be given to the user. As a result, the user can continuously play the game itself.

  The information processing apparatus may further include an output unit that outputs display information that is a basis of a screen on which the object selected by the second selection unit is presented.

  The “display information” may be information itself presented to the user (for example, image data, text data, etc.), or may be information (eg, HTML) for presenting the information to the user.

  In the above case, since the information of the card deleted from the box is presented, the user can know which card is deleted from the box (that is, which card remains in the box).

  The output means serves as a basis for a screen for presenting the object selected by the second selection means after outputting display information as a basis for a screen for presenting the object selected by the first selection means. Display information may be output.

  In the above case, after presenting the card information given to the user to the user, the card information deleted from the box is presented to the user, so which card was deleted from the box rather than which card was granted ( That is, the user's consciousness can be directed to which card remains in the box.

In addition, a user instruction for identifying an object to be released from association with the population among the objects selected by the second selection unit is received via a screen based on the display information output by the output unit. A reception means,
The first updating unit may update the population information so that the association between the object specified by the instruction received by the receiving unit and the population is released.

  In the above case, since the designation of the card to be deleted from the box is accepted from among the deletion candidate cards, which card to delete from the box has an advantage in the progress of the game for the box lottery process (that is, the game The above strategy) can be made to think about the user. Thereby, the preference of a game can be improved.

Further, the second selection means may select the predetermined number of objects from objects having types satisfying a predetermined condition.
Further, the type is a rare value of the object,
The type satisfying the predetermined condition may be a rare value equal to or less than a predetermined value.

  The “type” may be a numerical parameter of the object or a non-numeric parameter. The “non-numeric parameter” may be a rare value or an attribute of the object.

  In the above case, since a card having a type satisfying a predetermined condition (for example, a card having low rarity) is deleted from the box, a probability that a card having a type not satisfying the predetermined condition (for example, a card having high rarity) is given. Can be increased.

  The second selection unit may determine the predetermined number based on the number of objects associated with the population.

  The “number of objects associated with the population” may be the remaining number of objects included in the box, or the remaining number for each parameter (for example, rare value) of the objects included in the box. Also good.

  In this case, the greater the remaining number of cards contained in the box (that is, the smaller the number of executions of the box lottery process), the greater the increase in the probability that a card with a high rare value will be given in one box lottery process. Can be increased. As a result, it is possible to give a motivation to make the user who uses the box lottery process less frequently executed to use the box lottery function. In particular, in a social game, the user who uses the function provided in the game has a tendency to give up the continuation of the game play, so that the user who uses the box lottery process has a small number of times to use the function. This is extremely effective in continuously playing the game itself.

Another aspect of the present invention provides:

A second updating means for updating possession information stored in the storage device,
Is an information processing apparatus.

In order for the user to continue playing the game, it is important to give the user a sense of expectation for the game. In order to give the user a sense of expectation for the game, it is effective to allow the user to repeatedly use the functions of the game. However, simply presenting the card information to be given to the user in the box lottery process is not sufficient as a motivation for using the box lottery function, and the user abandons continuation of the game play. It leads to.
In the information processing apparatus, information on cards (granting candidate cards) that may be given in the box lottery process is presented to the user before the card given to the user is determined. Therefore, the user experiences two lotteries (lottery of grant candidate cards and lottery of cards to be given to the user) in one box lottery process. Thereby, the preference of a box lottery function can be improved.

  In the above, in order to facilitate the understanding of the present invention, the reference numerals described in the drawings are appropriately described in parentheses, but the information processing apparatus and the like according to the present invention are thereby limited to the illustrated embodiments. It is not a thing.
