I purchased with a lot of game money. Since such game items may be obtained redundantly as the game progresses, they are often set to be exchangeable with other users in the game. As one method, there is direct exchange of game items between users, but exchange is not established unless the game items necessary for each other are held. In addition, since there are inevitably high demand for so-called rare items that exist in the game, they are traded for a large amount of game money. (Real money) may result in transactions, and may become a hotbed for crimes such as fraud. In order to prevent unreasonable profits and maintain the soundness of the game, simply prohibiting the trading of game items between users leaves game items unnecessary for the user, but is necessary for the progress of the game. Since one game item cannot be obtained, there is a problem that the progress of the game is hindered and the user's willingness is lost.

As a method for facilitating the exchange of game items between users, for example, Patent Document 1 describes a method of providing a place for indirectly exchanging game items between users by using an auction or a reverse auction.

When the virtual currency control unit 161a exchanges cash for the first virtual currency according to a user request, the virtual currency control unit 161a associates the requested first virtual currency with the user ID and stores the first virtual currency in the virtual currency database 161b. The virtual currency control unit 161a transfers the exchanged cash amount to a credit card or a server that manages the electronic money held by the user, and performs a settlement process. Since a known technique can be used for a credit card or electronic money settlement method, a detailed description is omitted.

When the first virtual currency is exchanged for the second virtual currency at the request of the user, the virtual currency control unit 161a associates the requested second virtual currency with the user ID and stores the second virtual currency in the virtual currency database 161b. . At this time, the virtual currency control unit 161a subtracts the exchanged first virtual currency and stores it in the virtual currency database 161b. Note that the virtual currency database 161b may be integrated with the user information database 157.

(Virtual currency)
In the present embodiment, the “virtual currency” is a virtual currency that can be used on a platform provided by the game providing system 100, and is a currency whose usage is limited by the game providing system 100. In the present embodiment, the “first virtual currency” is a currency that is irreversibly exchanged from cash, and is a common currency that can be used by the entire platform provided by the game providing system 100. Therefore, the first virtual currency is exchanged for cash at the request of the user, but it cannot be converted into cash in principle. The “second virtual currency” is a currency that is irreversibly exchanged from the first virtual currency, and is a currency that can be used only within a specific game provided by the game providing system 100. Therefore, the second virtual currency is exchanged with the first virtual currency at the request of the user, but cannot be returned to the first virtual currency in principle. In the present embodiment, games that can use the second virtual currency are limited to one or more games preset by the game providing system 100. Therefore, the second virtual currency is different for each game provided in the game providing system 100 or for each group of games (including one or more games), and the user can select another game or other group of games. The second virtual currency cannot be diverted.

In this embodiment, as will be described later, the second virtual currency is used as a currency for acquiring game items or trading. Therefore, the second virtual currency is limited to the acquisition of game items only in a specific game and the use in transactions, thereby reducing versatility and making it impossible to cash in cash. Accordingly, the second virtual currency can be distributed only within a specific game, and the game item transaction using the second virtual currency can be promoted. On the other hand, since the second virtual currency with limited usage and usage is significantly different in nature from cash, the act of obtaining unfair profits by transferring game items to a third party is suppressed and sound It is possible to provide a user with a highly specific game. In addition, the virtual currency according to the present invention is not limited to these, and another virtual currency whose usage is specified can be set and provided to the user.

The game item providing unit 163 is software or a module that associates a user with a game item and a database. FIG. 3 shows an example of the configuration of the game item providing unit 163. The game item providing unit 163 may be configured by, for example, a game item control unit 163a and a game item database 163b. The game item control unit 163a is software or a module that associates a user with a game item. The game item database 163b is a database stored in a main storage device such as a hard disk or a solid state disk (SSD), and stores a user ID and a game item in association with each other. The game item database 163b may be integrated with the user information database 157.

When the user purchases a game item with the second virtual currency held by the user, the game item control unit 163a associates the user ID with the game item and stores them in the game item database 163b. The purchase of the game item may be simply purchased with the second virtual currency in which the user holds the desired game item. In this embodiment, when purchasing a game item, for example, gacha (registered trademark) may be used. That is, when the user wishes to purchase a game item, the game item control unit 163a may randomly extract one game item from predetermined game items and provide it to the user.

The game item transaction unit 165 is software or a module that executes a game item transaction among a plurality of users. The game item trading unit 165 provides a place for trading game items between users in the game, and promotes trading of game items between users. Although direct transaction of game items between users is generally conceivable, in this case, it is difficult to eliminate fraud such as transaction of game items between users at a high price in cash. In the present embodiment, it is preferable that the game item transaction unit 165 does not perform direct transaction of game items between users but uses a predetermined transaction adjustment unit.

Examples of the predetermined transaction adjustment unit according to the present embodiment include an auction, a reverse auction, a method of randomly combining a seller or an exhibitor (first user) and a purchaser (second user). It is preferable to use it. Since a well-known technique can be applied to the transaction method by auction and reverse auction, detailed description is omitted. As a method of randomly combining a seller or seller (first user) and a purchaser (second user), for example, the game item transaction unit 165 determines a transaction price for each game item in advance. And store the transaction with a random combination of exhibitor and purchaser. As described above, in the game item transaction according to the present embodiment, the direct transaction between the exhibitor and the purchaser is prevented and the game item is transferred to a third party through a predetermined transaction adjustment unit. It is possible to suppress an act of obtaining an unfair profit and provide a highly sound game to the user.

The game item transaction unit 165 determines to change the game item associated with the exhibitor to be associated with the purchaser by using the predetermined transaction adjustment unit. The game item transaction unit 165 determines the consideration of the game item in the second virtual currency, subtracts the second virtual currency as the consideration of the game item from the second virtual currency held by the purchaser, and the exhibitor The second virtual currency subtracted from the purchaser is added to the second virtual currency held and stored in the virtual currency database 161b. The virtual currency control unit 161a described above may perform the second virtual currency settlement process between the purchaser and the seller. The purchased game item is deleted from the game items held by the exhibitor, changed to be associated with the purchaser, and recorded in the game item database 163b.

Moreover, in this embodiment, the game item transaction part 165 may collect the expense concerning transaction of a game item with a 2nd virtual currency from a user. For example, when the game item transaction unit 165 adds the second virtual currency to the exhibitor of the game item as a consideration for the game item, the game item transaction unit 165 subtracts a predetermined fee from the consideration to the exhibitor to the second virtual currency. May be added. In the present embodiment, the collection of such a fee is not limited to this. When the consideration for purchasing the game item is subtracted from the purchaser, the fee is subtracted with the second virtual currency. Also good.

The game providing unit 171 is software or a module that provides a game executed from the user terminal 110 via the network 190. The game provided by the game providing unit 171 may be any game as long as the game progresses by acquiring and using game items, such as a card game, a role playing game (RPG), and a battle game. As described above, in the present embodiment, the second virtual currency is a currency that can be used only within a specific game provided from the game providing unit 171.

(Game item)
Here, the game item which concerns on this embodiment is demonstrated. The game item according to the present embodiment may be in any form as long as it is related to the progress of the game. For example, when the game provided by the game providing system 100 is a card game, the game item may be a card, and when the game item is a competitive game, the game item may be a weapon or equipment. Good. In the present embodiment, the game item is not limited to the item (first game item) that can be purchased with the above-described second virtual currency. For example, the second game acquired by the user as the game progresses An item may be set. That is, the user may be able to acquire a game item when a predetermined stage of the game is cleared.

Moreover, you may enable it to strengthen the game item which a user owns according to progress of a game. For example, in response to clearing a predetermined stage of the game, the game providing unit 171 may provide the user with a third virtual currency that cannot be exchanged for the first virtual currency and the second virtual currency. . The virtual currency control unit 161a stores the provided third virtual currency in association with the user ID in the virtual currency database 161b. A user may acquire the 3rd game item which strengthened the level of the 1st game item or the 2nd game item by consuming the 3rd virtual currency. At this time, the virtual currency control unit 161a may subtract the third virtual currency consumed from the third virtual currency associated with the user and store the result in the virtual currency database 161b.

In FIG. 1, the control unit 151, the communication unit 153, the virtual currency providing unit 161, the game item providing unit 163, and the game item transaction unit 165 are installed separately from the server 150 as the game item transaction system 160. You can also. That is, the server that provides the game and the game item transaction server may be separated. By separating in this way, the game item transaction system 160 can be widely used for many games.

A game with high soundness by reducing the versatility and making it impossible to convert it into cash, thereby promoting the transaction of game items and suppressing the act of obtaining unfair profits by transferring game items to a third party. Can be provided to the user.

[How to provide games]
A game providing method using the game providing system 100 according to this embodiment will be described below.

FIG. 4 is a diagram illustrating a data flow of the game item exhibitor user terminal 111, the game item purchaser user terminal 113, and the server 150 in the game providing system 100 according to the present embodiment. The user exhibiting the game item requests user authentication in order to establish a connection to the server 150 via the user terminal 111 (S100). As shown in FIG. 5, when the server 150 receives a user authentication request (S101), the user authentication unit 155 requests the user terminal 111 to input a user ID and password (S103). The user ID and password are character strings set in advance for the user to use the game providing system 100, and are stored in the user information database 157. If the user ID is a character string different from that of other users, the user authentication unit 155 may automatically generate the ID, or the user may arbitrarily set the ID. The user password may be automatically generated by the user authentication unit 155 or may be arbitrarily set by the user.

When the server 150 receives the user ID and password from the user terminal 111 (S105), the user authentication unit 155 refers to the user information database 157 and verifies whether the stored ID and password match (S107). . When the user ID and password received from the user terminal 111 match the ID and password stored in the user information database 157, the server 150 uses the user terminal 111 as a user who can use the game providing system 100. And establish a connection with the user terminal 111 (S150).

The user can irreversibly exchange cash for the first virtual currency that is a common currency that can be used in the entire platform provided by the game providing system 100. Further, the user can irreversibly exchange the first virtual currency for the second virtual currency, which is a currency that can be used only within a specific game. At this time, the second virtual currency can be exchanged up to the first virtual currency owned by the user.

When the user requests the start of the game via the user terminal 111 (S200), the game providing unit 171 executes the game and transmits game data to the user terminal 111 (S250). The user can purchase game items with the second virtual currency in order to proceed with the game.

If the user (exhibitor) wants to sell the game item, the user (exhibitor) requests the server 150 to exhibit the game item via the user terminal 111 (S300). On the other hand, when a user (purchaser) wants to purchase a game item, he / she requests the server 150 to purchase the game item via the user terminal 113 (S350).

The game item transaction unit 165 combines the exhibitor and the purchaser using the predetermined transaction adjustment means described above (S400). As shown in FIG. 6A, the game item transaction unit 165 determines the consideration of the game item in the second virtual currency (S450), and the second virtual currency held by the purchaser is the consideration of the game item. If the second virtual currency held by the purchaser is greater than the price of the game item, the game item may be changed to be associated with the purchaser (S455). At this time, when the second virtual currency held by the purchaser is less than the consideration of the game item, an error may be displayed on the user terminal 113 of the purchaser (S460). The game item control unit 163a deletes the game item data associated with the seller (S500), and stores it in the game item database 163b in association with the purchaser's user ID (S550).

Further, as shown in FIG. 6B, the game item transaction unit 165 subtracts the second virtual currency as a consideration for the game item from the second virtual currency held by the purchaser (S600), and the exhibitor The second virtual currency subtracted from the purchaser is added to the second virtual currency held and stored in the virtual currency database 161b (S650). The purchaser can proceed with the game using the game item purchased in this way.

As described above, in the game providing system according to the present embodiment, the virtual currency used in the game is restricted to be used only in a specific game, and the use is specialized in the purchase of the game item. A game with high soundness by reducing the versatility and making it impossible to convert it into cash, thereby promoting the transaction of game items and suppressing the act of obtaining unfair profits by transferring game items to a third party. Can be provided to the user.
