Items are various items used in the game, such as battle cards, characters, weapons, equipment, ornaments, plants, food, etc. that make up the user's deck. Good. The item type is a numerical value indicating the scarce value of the item, a numerical value indicating the category of the item, or the like. Hereinafter, although an item kind is demonstrated as what is a numerical value showing the scarce value of an item, it is not restricted to this.

  Specifically, the storage unit 11 stores the information separately for each table and data. The storage unit 11 stores an item data table 111 and an item group table 112.

  The item data table 111 stores data such as an image related to an item provided to the user (hereinafter referred to as item data) in association with item identification information. Item identification information is an identifier for uniquely identifying an item in this system. An example of the item data table 111 is shown in FIG. As shown in FIG. 2, for example, item data in the item data table 111 includes item identification information “UNI1”, item name “item A”, item image “item A image”, attack power “1000”, defense power “500”. , Item type “3” and specific item flag “1”. Attack power and defense power are parameters related to the strength of an item. The specific item flag is data represented by an integer of 0 or more. An item whose specific item flag is 1 or more is called a specific item. As will be described later, the communication terminal 2 can make an item acquisition request from a predetermined item group to the game server 1 using a specific item. The specific item can be used in the game in the same manner as the non-specific item. Here, the value of the specific item flag being a means that the specific item is included in the a-th item group. The specific item flag is not limited to this, and may be any numerical value or character string as long as the specific item can be identified. The image data may be in any image format such as JPEG, GIF, or PNG.

  FIG. 3 shows an example of the item group table 112. Although an example in which three item groups are stored is shown in the item group table 112, the present invention is not limited to this, and N item groups (assuming that N is an integer of 2 or more) are stored. Good. The item group table 112 includes item identification information included in each item group. As shown in FIG. 3, for example, the first item group includes item identification information “UNI1”, “UNI2”, “UNI3”, and “UNI4”. Similarly, the second item group and the third item group also include item identification information. In the example shown in FIG. 3, each item group includes one specific item. Each item group may include two or more specific items, that is, each item group includes at least one specific item.

  FIG. 4 shows the distribution of item types of items included in each item group. As illustrated in FIG. 4, the second item group includes many items having a higher item type value than the items included in the first item group. The third item group includes many items having a higher item type value than the items included in the second item group. That is, the (m + 1) th item group includes many items having a rare value higher than items included in the mth item group. Here, m is 1 ≦ m ≦ N−1.

  As shown in FIG. 4, the second item group preferably includes many specific items having a higher item type value than the specific items included in the first item group. The third item group includes many specific items having a higher item type value than the specific items included in the second item group. That is, the (m + 1) th item group includes many specific items having a rare value higher than the specific items included in the mth item group.

  The control unit 12 performs various controls related to the game server 1. For example, the control unit 12 receives an item acquisition request from the communication terminal 2. Here, the item acquisition request includes an item acquisition request using a virtual currency such as a coin and an item acquisition request using a specific item. The item acquisition request using a virtual currency such as a coin is an item acquisition request for exchanging the virtual currency and the item using the virtual currency held by the user of the communication terminal 2. On the other hand, the item acquisition request by the specific item is an item acquisition request for exchanging the specific item with the item using the specific item held by the user of the communication terminal 2. When receiving an item acquisition request in virtual currency such as coins from the communication terminal 2, the control unit 12 refers to the item group table 112 of the storage unit 11 and extracts items to be provided to the communication terminal 2 from the first item group. To decide. Then, the control unit 12 provides the item to the communication terminal 2. Specifically, the control unit 12 refers to the item data table 111 and provides an item image corresponding to item identification information related to the provided item to the communication terminal 2 via the communication unit 10.

  Moreover, the control part 12 extracts the item provided to the communication terminal 2 from the 2nd item group with reference to the item group table 112, when the item acquisition request by the specific item of a 1st item group is received from the communication terminal 2. decide. Then, the control unit 12 provides the item to the communication terminal 2. Moreover, the control part 12 extracts the item provided to the communication terminal 2 from the 3rd item group with reference to the item group table 112, when the item acquisition request by the specific item of a 2nd item group is received from the communication terminal 2. decide. Then, the control unit 12 provides the item to the communication terminal 2. That is, when the control unit 12 receives an item acquisition request for a specific item of the m-th item group, the control unit 12 extracts the item from the m + 1 item group and provides the item to the communication terminal 2. The method of extraction may be selected randomly by the control unit 12 from each item group, or may be selected by a lottery based on a predetermined algorithm. In addition, the control part 12 determines the item group containing the said specific item by the specific item flag of the item data table 111, when the item acquisition request by a specific item is received. As described above, the control unit 12 functions as a first lottery means that can provide a user with some items among a plurality of types of items having different rarity values by lottery. It functions as a second lottery means that can provide a plurality of types of items with different rarity values by lottery to a user who has a predetermined item (that is, a specific item) among items that can be provided by the lottery means. Here, as described above, the second lottery means is more likely to provide an item having a higher rarity value than the item that can be provided by the first lottery means.

  The communication terminal 2 includes a communication unit 20, a display unit 21, an operation unit 22, and a control unit 23.

  The communication unit 20 communicates with the game server 1 by at least one of wireless or wired. Specifically, the communication unit 20 transmits an item acquisition request to the game server 1 based on the operation of the operation unit 22 by the user. Further, the communication unit 20 receives provision of an item for the item acquisition request from the game server 1.

  The control unit 23 performs various controls related to the communication terminal 2. For example, the control unit 23 transmits an item acquisition request using virtual currency such as coins to the game server 1 via the communication unit 20 based on the operation of the operation unit 22 by the user. Further, the control unit 23 transmits an item acquisition request based on a specific item to the game server 1 via the communication unit 20 based on the operation of the operation unit 22 by the user.

  Next, the operation of the communication system according to the present invention will be described with reference to the flowchart shown in FIG.

  First, the control unit 23 of the communication terminal 2 transmits an item acquisition request using virtual currency such as coins to the game server 1 via the communication unit 20 based on the operation of the operation unit 22 by the user (step S1).

  Next, the control unit 12 of the game server 1 refers to the item group table 112 of the storage unit 11 and extracts and determines items to be provided to the communication terminal 2 from the first item group (step S2). And the control part 12 provides the said item to the communication terminal 2 (step S3). Specifically, the control unit 12 refers to the item data table 111 and provides an item image corresponding to item identification information related to the provided item to the communication terminal 2 via the communication unit 10. Here, the case where the item provided by the control unit 12 is a specific item included in the first item group will be described below.

  Subsequently, the control unit 23 of the communication terminal 2 sends an item acquisition request by the specific item received in step S3 based on the operation of the operation unit 22 by the user (that is, an item acquisition request by the specific item of the first item group). It transmits to the game server 1 via the communication part 20 (step S4).

  Subsequently, when receiving an item acquisition request for the specific item of the first item group from the communication terminal 2, the control unit 12 refers to the item group table 112 and extracts items to be provided to the communication terminal 2 from the second item group. (Step S5). And the control part 12 provides the said item to the communication terminal 2 (step S6). Specifically, the control unit 12 refers to the item data table 111 and provides an item image corresponding to item identification information related to the provided item to the communication terminal 2 via the communication unit 10. Here, the case where the item provided by the control unit 12 is a specific item included in the second item group will be described below.

  Subsequently, the control unit 23 of the communication terminal 2 sends an item acquisition request by the specific item received in step S6 based on the operation of the operation unit 22 by the user (that is, an item acquisition request by the specific item of the second item group). It transmits to the game server 1 via the communication part 20 (step S7).

  Subsequently, when receiving an item acquisition request for the specific item of the second item group from the communication terminal 2, the control unit 12 refers to the item group table 112 and extracts items to be provided to the communication terminal 2 from the third item group. (Step S8). And the control part 12 provides the said item to the communication terminal 2 (step S9). Specifically, the control unit 12 refers to the item data table 111 and provides an item image corresponding to item identification information related to the provided item to the communication terminal 2 via the communication unit 10. Then, the process ends.

  As described above, according to the present invention, the communication terminal 2 can make an item acquisition request for an item belonging to another item group by a specific item provided from the game server 1, and a variation of an acquisition method such as a battle card can be obtained. Can be increased. In addition, other item groups contain items with higher rarity value than items belonging to the item group that acquired the specific item, so the acquisition predictability of cards with high rarity value etc. is improved and interest in the game is improved. Can be made.

  In addition, in this embodiment, since it has shown about the case where there are three item groups, the item acquisition request by a specific item does not continue after step S9, but when there are four or more item groups, item acquisition by a specific item is performed. The request continues.

  The game server 1 may present the communication terminal 2 with a list of items and specific items included in the first item group to the third item group based on the item presentation request from the communication terminal 2. That is, the game server 1 may present the communication terminal 2 with a list of items and specific items included in the m-th item group. Prior to step S1 or step S4 in FIG. 5, the communication terminal 2 transmits the request to the game server 1 so that the user can improve the foreseeability of the item and the specific item obtained by the item acquisition request. You can improve your interest in.

  Furthermore, the game server 1 may include the acquisition probability of each item and the specific item in the list of items and specific items included in the first item group to the third item group. In this case, the control unit 12 of the game server 1 divides the number of items and specific items included in the first item group to the third item group by the total number of items and specific items in each item group, thereby And the acquisition probability of the specific item is calculated and included in the list. By doing in this way, the user of the communication terminal 2 can recognize the item obtained by the item acquisition request and the acquisition predictability of the specific item more accurately by displaying the acquisition probability.

  Note that the storage unit 11 of the game server 1 may store the user item list 113. The user item list 113 is data including identification information of items owned by each user. The user item list is stored in the storage unit 11 for each user. And when the specific item is contained in the item which a certain user holds based on the user item list | wrist 113 based on the user item list | wrist 113, the item acquisition request | requirement by this specific item is possible for the said communication terminal 2 of the said user. May be notified.

  FIG. 6 shows an example of the user item list 113 of a certain user. The user item list 113 includes “UID1”, “UID6”, “UID7”,. Among these, the item of “UID1” is a specific item. In this case, based on the user item list 113, the control unit 12 of the game server 1 notifies the user's communication terminal 2 that an item acquisition request using the specific item is possible. Specifically, the control unit 12 of the game server 1 presents an item list screen with reference to the user item list 113 based on a request from the communication terminal 2. FIG. 7 shows an example of the item list screen. The item list screen includes item images 1131 to 1133 and description information 1141 to 1143 of each item. When the item according to the item image 1131 is a specific item, the item acquisition request link 1151 is included together with the description information 1141 of the item. When the item acquisition request link 1151 is clicked, the item can be acquired from the corresponding item group by the specific item related to the item image 1131. For example, the link 1151 indicates “turn a special gacha” or the like. The communication terminal 2 transmits an item acquisition request for the specific item to the game server 1 based on an operation such as clicking or touching the link 1151 by the user. By comprising in this way, the convenience of the user who holds a specific item can be improved.

  The user item list 113 may include the time when the game server 1 provided each item to the communication terminal 2. That is, the game server 1 may store, for example, the time when the specific item of the mth item group is provided to the communication terminal 2 in the storage unit 11. And the control part 12 of the game server 1 is only when the time which received the item acquisition request by a specific item is within a predetermined period from the time which provided the specific item stored in the memory | storage part 11 to the communication terminal 2. Items are extracted from the (m + 1) th item group and provided to the communication terminal 2.

  FIG. 8 shows a user item list 113b which is a modification of the user item list 113 of a certain user A. The user item list 113b includes, for example, item identification information “UID1” and provision time “2012/8/10 10:30”. Here, the item of “UID1” is a specific item included in the first item group. It is assumed that the current time is “2012/8/11 19:30”. The predetermined period is 48 hours. In this case, since the control unit 12 of the game server 1 receives the item acquisition request by the specific item is within a predetermined period from the time when the specific item stored in the storage unit 11 is provided to the communication terminal 2, The item is extracted from the second item group and provided to the communication terminal 2. By comprising in this way, it can accelerate | stimulate making the item acquisition request | requirement by the said specific item to the communication terminal 2 within a predetermined period after providing a specific item, and can improve a user's interest with respect to a game.
