  Next, functions of the service providing system 10 of the present embodiment will be described. FIG. 2 is a block diagram schematically showing the functions of the system 10. As illustrated, the system 10 controls an information storage management unit 41 that stores and manages various information, a basic function control unit 43 that controls basic functions, a service control unit 45 that controls provided services, and a lottery. And a lottery control unit 47. These functions are realized by the cooperation of hardware such as the CPU 11 and the main memory 12 and various programs and data stored in the storage 15 etc. This is realized by the CPU 11 executing an instruction included in the program. In addition, part or all of the functions illustrated in FIG. 2 may be realized by cooperation of the system 10 and the user terminal 30, or may be realized by the user terminal 30.

  The information storage management unit 41 of the system 10 stores and manages various information in the storage 15 or the like. For example, as illustrated in FIG. 2, the information storage management unit 41 may have a user information table 411 that manages information on the user of the provided service.

  The basic function control unit 43 of the system 10 executes various processes related to control of the basic function. For example, the basic function control unit 43 transmits HTML data or control data of various screens related to the basic function to the user terminal 30, and responds to operation input by the user via the screen displayed on the user terminal 30. Processing is executed, and HTML data or control data corresponding to the result of the processing is transmitted to the user terminal 30. The basic functions controlled by the basic function control unit 43 include, for example, login processing (user authentication), charge control, and user management (for example, updating of the user information table 411).

  The service control unit 45 of the system 10 performs various processes related to control of provided services. For example, the service control unit 45 transmits HTML data or control data of various screens related to the provided service to the user terminal 30, and responds to operation input by the user via the screen displayed on the user terminal 30. The processing is executed, and HTML data or control data according to the result of the processing is transmitted to the user terminal 30.

  In the present embodiment, the service control unit 45 executes a lottery (hereinafter, may be referred to as a “period limited lottery”) which is performed for a limited period of time for a user who satisfies the predetermined condition. It is comprised so that the lottery execution authority for can be provided. The presence or absence of the lottery execution authority of each user is managed, for example, in the user information table 411.

  In the present embodiment, the predetermined condition for giving the lottery execution authority is configured to be satisfied more easily as the time passes in the predetermined period in which the lottery is performed. That is, the difficulty level for satisfying the predetermined condition decreases as the time point in the predetermined period is later (closer to the end point of the period).

  The lottery control unit 47 of the system 10 executes various processes related to control of the lottery. For example, the lottery control unit 47 transmits HTML data or control data of various screens regarding the lottery to the user terminal 30, and various processes in response to the operation input by the user via the screen displayed on the user terminal 30. To transmit to the user terminal 30 HTML data or control data according to the result of the process. The lottery controlled by the lottery control unit 47 may include another lottery (for example, a lottery with a non-limited period, etc.) in addition to the period-limited lottery described above. Further, the process executed by the lottery control unit 47 includes an individual lottery process (for example, a process of selecting a winning content from among a plurality of lottery target contents based on the generated random numbers).

  In the present embodiment, the lottery control unit 47 is configured to control the execution of the period-limited lottery according to the request from the user having the lottery execution authority. In the present embodiment, the time-limited lottery is configured to be more disadvantageous to the user as the time in the predetermined period elapses. That is, the lottery condition for the period limited lottery becomes worse for the user as the time point in the predetermined period is later (as the end point of the period is approached). For example, when the lottery control unit 47 receives a lottery execution request from a user having lottery execution authority via the user terminal 30, the lottery control unit 47 is configured to execute a lottery process according to the lottery condition at that time.

  As described above, the service providing system 10 of the present embodiment grants the user who satisfies the predetermined condition the lottery execution authority to execute the period limited lottery, and the predetermined condition executes the period limited lottery. The more the time in a given predetermined period elapses, the easier it is to satisfy the time, and the period-limited lottery is configured to be more disadvantageous to the user as the time in the predetermined period elapses. That is, since the number of users who can execute the time-limited lottery is small at an early point in a predetermined period and the lottery condition is relatively advantageous for the user, the user who can execute the lottery at an early point is To create a sense of speciality and to promote the early implementation of the lottery. As a result, activation of the lottery performed in a predetermined period is supported.

  Here, the lottery provided by the system 10 is for the user to acquire lottery target content which is virtual and electronic content to be a lottery target. The lottery target content in the present embodiment may include various virtual and electronic contents. For example, the lottery target content includes characters, items, cards, and the like that can be used in an online game or the like as a provided service. Further, for example, the lottery target content includes image content (sometimes called “stamp” or the like) that can be used in the SNS. Also, for example, the lottery target content includes various virtual currencies available in the provided service. Also, for example, the lottery target content includes an item (lottery ticket) or the like for executing another lottery.

  In the present embodiment, the predetermined conditions for acquiring the lottery execution authority may be configured as various conditions. For example, the predetermined condition includes a condition satisfied through the execution (play) of a game executable in the provided service. In this case, for example, the service control unit 45 controls the execution of the first game executable in the first period included in the predetermined period in which the time-limited lottery is performed, and is included in the predetermined period. And the second game, which is executable to control the execution of the second game that can be performed in the second period later than the first period, the second game being compared to the first game via its execution It is configured that the satisfaction of the predetermined condition is easy (that is, the degree of difficulty for satisfying the predetermined condition is lower in the second game than in the first game). Such a configuration enables the user to satisfy predetermined conditions (acquires lottery execution authority) through the execution of the game, and as a result, activation of the lottery performed in a predetermined period is supported.

  In the present embodiment, the lottery control unit 47 can be configured to consume the lottery item held by the user along with the execution of the lottery. For example, the lottery control unit 47 consumes a predetermined unit quantity (for example, one) of lottery items in association with the execution of one lottery. The item for lottery may be configured to be given to the user at various timings. For example, the service control unit 45 may select the item for lottery according to the result of the first and second games described above. It may be configured to be granted to a user. Such an arrangement may provide the user with fun regarding the acquisition of lottery items.

  In the present embodiment, the predetermined condition includes a condition that is satisfied based on the user's attribute value. The attribute value includes values of various parameters that can be set for the user, and includes, for example, a level, an experience value, a group to which the user belongs, and the like. For example, the predetermined condition is satisfied in a first period included in the predetermined period, in a second period which is satisfied by the user of the first level or higher and later than the first period included in the predetermined period. A second level user above the first level may be configured to be satisfied. Such a configuration makes it possible to grant the lottery execution authority based on the user's attribute value.

  Further, the predetermined condition includes a condition satisfied in response to being invited by another user who has the lottery execution authority. For example, the predetermined condition may be configured to include, in addition to the above condition satisfied based on the user's attribute value, a condition satisfied in response to being invited by another user who has the lottery execution authority. . In this case, for example, at the start of a predetermined period, the user whose predetermined attribute value is within a predetermined range (for example, the level is equal to or higher than the threshold) satisfies the predetermined condition and acquires lottery execution authority. Thereafter, in response to the invitation by the user having the lottery execution authority, another user acquires the lottery execution authority. Such a configuration can acquire the lottery execution authority at the start point of a predetermined period, and then can make the user who invites other users feel special. In this case, the service control unit 45 may be configured to give the above-described lottery item to the user in response to the invitation of the other user. Such configuration promotes the user to invite other users, and as a result, the activation of the lottery performed in a predetermined period is supported.

  As described above, the time-limited lottery in this embodiment is more disadvantageous to the user as time passes in a predetermined period. For example, the lottery may be configured such that the value (for example, the rarity of a card, etc.) of the lottery target content becomes lower as the time in the predetermined period elapses. Specifically, for example, in the first period in the predetermined period, the lottery target content includes the first content having the first value, and the second period is later than the first period. The second content having a second value lower than the first value is included in the lottery target content instead of the first content.

  Also, for example, the time-limited lottery may be configured such that the probability of winning a specific lottery target content decreases as time in a predetermined period elapses. Specifically, for example, in the first period in a predetermined period, the winning probability of a specific high-value content (for example, a content with the highest value of parameters such as rarity among the lottery target contents) is 20 %, And in a second period later than the first period, the probability of winning the particular content is 10%.

  Also, for example, the time-limited lottery can be configured such that a plurality of users share the lottery target content in one virtual box. Specifically, as an individual lottery process, the lottery control unit 47 selects a winning content from among a plurality of lottery target contents included in one virtual box common to a plurality of users, and selects the selected winning content. It may be configured to exclude from the virtual box. In this case, the virtual box includes the first set of lottery target content at the start point of the predetermined period, and then, according to the increase in the number of users having lottery execution authority, the first of the lottery target content A set of two may be configured to be added. Then, the second set of lottery target content is configured to be disadvantageous to the user as compared to the first set.

  Next, a specific example of the service providing system 10 of the present embodiment having such a function will be described. The system 10 in this specific example provides an online card game to the user of the user terminal 30, and also provides a lottery for acquiring available cards in the online card game. And although details will be described later, in this example, a lottery for acquiring a special lottery ticket (for example, a lottery ticket having a high probability of winning a special card) is provided as a period limited lottery executed in a predetermined period. Be done.

  FIG. 3 exemplifies the information managed by the user information table 411 in this example. The user information table 411 manages information for each user, and as shown in the figure, shows “presence or absence of participation right (lottery execution authority) of period limited lottery in association with“ user ID ”identifying individual users. Information such as "participation presence / absence flag" and "the number of exclusive medals", which is the number of exclusive medals (items for lottery) consumed with the execution of the time-limited lottery, is managed.

  FIG. 4 illustrates the time-limited lottery top screen 50 displayed on the user terminal 30. As shown in FIG. The screen 50 is displayed in response to the selection of a banner included in the top screen of the online card game of this example. The period limited lottery top screen 50 is, as shown in the figure, an event top button 52 displayed as "event TOP", a period limited lottery button 54 displayed as "period limited lottery", and a current of period limited lottery A first display area 56 for displaying the lottery conditions and a second display area 58 for displaying information on the special content (eyeball content) having the highest value among the lottery target contents at that time of the time-limited lottery.

  The period limited lottery top screen 50 in FIG. 4 corresponds to the case where the user does not have the right to participate in the period limited lottery. In this example, the participation right is given as a reward for the event. When the user selects the event top button 52, the top screen of the event for the user to obtain participation is displayed.

  Here, an event for acquiring participation will be described. In this example, an event for acquiring the participation right switches during the period in which the time-limited lottery is performed. FIG. 5 is a diagram for explaining three events held during the period of the time-limited lottery. As illustrated, in the first period of the entire period in which the time-limited lottery is performed, an event of the inter-person match game is held. The inter-person match game is, for example, a non-real-time match that is played using a deck composed of a plurality of cards, and parameters of each deck of two users who play the match (eg, attack power, and A battle process is executed based on the value of defense power etc.). Then, in the event of the inter-person match game, the participation right of the time-limited lottery is given as a winning reward to the user whose number of winnings has reached a predetermined number.

  Further, as shown in FIG. 5, in the second period following the first period, an event of the quest game is held. The quest game is a game that is cleared by a user searching the game space and defeating a boss, and is played individually by each user. Then, in the event of the quest game, the right to participate in the time-limited lottery is given as a clear reward when the quest is cleared.

  Further, as shown in FIG. 5, in the third period following the second period, an event of the inter-team competition game is held. The inter-team competition game is, for example, a real-time type competition played using a deck of each of a plurality of users forming a team, and a deck parameter of each user forming each of two teams competing (for example, A battle process is executed based on the values of the attack power and the defense power. Then, in the event of the inter-team competition game, the participation right of the time-limited lottery is given as the participation reward to the user who has participated in the competition game.

  Here, in this example, the clear reward of the quest game in the second period is more easily available to the user than the winning reward of the inter-person match game in the first period, and the quest in the second period is also quest. The reward for participating in the inter-team match game in the third period is easier for the user to obtain than the clear reward for the game. In other words, the right to participate in the time-limited lottery becomes lower in difficulty of acquisition as time passes in the period in which the time-limited lottery is performed (conditions for acquiring the right to participation become easier to satisfy).

  Returning to FIG. 4, the top screen of the event displayed when the event top button 52 of the time-limited lottery top screen 50 is selected corresponds to a period (one of the first to third periods) in which the time is included. Configured as a screen for executing a game.

  The time limited lottery button 54 of the time limited lottery top screen 50 is configured to be selectable when the user has the participation right, and can not be selected when the user does not have the participation right. Since the screen 50 of FIG. 4 is an example when the user does not have the participation right, the time-limited lottery button 54 can not be selected. Further, below the period limited lottery button 54, the number of exclusive medals to be consumed along with the execution of the period limited lottery is displayed (0 in the example of FIG. 4). The number of exclusive medals held is managed in the user information table 411.

  Here, in this example, the dedicated medal is given to the user through the execution of the above-described event (game play) for acquiring the participation right. Specifically, in the inter-person match game of the first period and the inter-team match game of the third period, dedicated medals of a quantity corresponding to the damage given to the enemy are given to the user. In addition, in the quest game of the second period, a dedicated medal of a quantity corresponding to the number of points acquired through the quest is given to the user.

  The first display area 56 of the time limited lottery top screen 50 displays the current lottery conditions of the time limited lottery. Although described later in detail, the time-limited lottery is configured to change the lottery target content and the winning probability during that period, and the first display area 56 is a current lottery condition at that time. A plurality of lottery target contents are displayed together with respective winning probabilities. In the example of FIG. 4, three contents of lottery ticket A, item X, and 100 coins are included as current lottery target contents. The winning probability of each content is 40% for the lottery ticket A, 30% for the item X, and 30% for 100 coins. Among the lottery target contents, the value for the user is the highest for the lottery ticket A, the second highest for the item X, and the lowest for 100 coins. That is, in this example, the lottery ticket A is the most valuable lottery target content (special content) among the current lottery target contents.

  The second display area 58 of the time limited lottery top screen 50 displays the special content (eyeball content) and the change (schedule) of the winning probability during the period of the time limited lottery. As illustrated, in this example, the special content in the first period (from January 10 to January 18) in which the inter-person match game is played is the lottery ticket A. In addition, the winning probability of the lottery ticket A becomes lower as time passes in the first period. Specifically, the winning probability of the lottery ticket A is 40% in the first three days, 30% in the next three days, and 20% in the last three days during the nine-day period. Further, the special content in the second period (from January 19 to January 27) in which the quest game is played is the lottery ticket B. In addition, as in the case of the lottery ticket A which is the special content of the first period, the winning probability of the lottery ticket B becomes lower with the lapse of time in the second period, specifically 40% for the first 3 days Yes, 30% for the next 3 days and 20% for the last 3 days. Further, the special content in the third period (from January 28 to February 6) in which the inter-team battle game is played is item X. Also, like the lottery tickets A and B, which are special contents of the first and second periods, in the third period, the probability of winning the item X decreases with the passage of time, and specifically, for the first three days Is 40%, the next 3 days 30% and the last 3 days 20%. As the probability of winning these special contents decreases, the probability of winning other contents increases.

  Here, the value for the user is highest for the lottery ticket A, next highest for the lottery ticket B, and lowest for the item X. For example, the lottery ticket A is a lottery ticket in which the probability of winning a special card is set to 50%, and the lottery ticket B is a lottery ticket in which the probability of winning a special card is also set to 30%. .

  Thus, in this example, the special content and the winning probability thereof change during the period of the limited lottery, and the earlier the time point in the whole period, the higher the value of the special content, and the first to third The earlier the point in time, the higher the probability of winning special content. In other words, the time-limited lottery in this example is configured to be more disadvantageous to the user as the time in the period in which the lottery is performed elapses.

  FIG. 6 illustrates the time-limited lottery top screen 50 when the user has the right to participate in the time-limited lottery. As illustrated, when the user has the participation right, the event top button 52 on the screen 50 illustrated in FIG. 4 is not displayed, and the time-limited lottery button 54 can be selected. Further, the display contents in the first display area 56 and the second display area 58 are changed according to the change of the lottery condition.

  When the user selects the time-limited lottery button 54, the lottery execution screen 60 illustrated in FIG. 7 is displayed on the user terminal 30. As illustrated, the lottery execution screen 60 has a lottery execution button 62 displayed as "performing a lottery" and a first display area 66. On the upper side of the lottery execution button 62, the number of dedicated medals required for one lottery (100 in this example) and the number of dedicated medals held by the user (2000 in this example) are displayed. ing. Similar to the first display area 56 of the time-limited lottery top screen 50, the first display area 66 displays the current lottery conditions.

  When the user selects the lottery execution button 62, the lottery is executed. Specifically, the lottery according to the current lottery conditions is executed (for example, determination of the winning content based on the generated random number is performed), and a screen indicating the lottery result is displayed. The winning content is given to the user, and the user's dedicated medal is consumed along with the execution of the lottery. In addition, the participation right granted once is not consumed along with the execution of the lottery (in other words, the user who has been granted the participation right can execute the limited lottery for the number of times corresponding to the number of dedicated medals held) . In addition, the number of wins is limited to one for the special content (specifically, lottery ticket A, lottery ticket B, and item X) for each of the first to third periods (only one can be obtained. You may do).

  In the example described above, the right to participate in the time-limited lottery is given to the user as the reward of the event, but in the present embodiment, the method of giving the right of participation is not limited to this. For example, in another example of the present embodiment, at the starting point of the period-limited lottery period, the participation right is granted to a user classified as a heavy user (for example, a user whose level is equal to or more than a predetermined value). The right of participation is given to the other users by the invitation by the user who has the right of participation. FIG. 8 is a diagram for explaining how the participation right is granted in this example. As shown, participation rights are given in advance to a plurality of users classified as heavy users, and each heavy user invites up to five other users for a limited time lottery (the participation right is granted) can do. In addition, users who have participation rights other than heavy users (that is, users invited by other users including heavy users) invite up to three other users to a time-limited lottery (grant the participation rights) be able to. Then, each time a user is invited to another user, a predetermined number of dedicated medals are given to the user.

  In the example described above, the lottery target content and the winning probability thereof change during the period of the limited time lottery, but in another example of the present embodiment, the lottery target content in one virtual box is changed by a plurality of users. Configured to compete. FIG. 9 is a diagram for explaining changes in the contents of the virtual box in this example. As illustrated, at the start point (initial state) of the period limited lottery period, the virtual box includes five lottery tickets A, ten items X, and 100 100 coins. Then, when the number of users having the participation right exceeds 200, the first replenishment of the virtual box is performed. The lottery target content to be added to the virtual box in the first replenishment is three lottery tickets A, ten items X, and 200 100 coins. As described above, the first replenishment content is disadvantageous for the user as compared with the content of the virtual box in the initial state (the ratio of the lottery ticket A which is the special content (win probability) is low). After that, when the number of users having the participation right exceeds 1000, the second replenishment for the virtual box is performed. The lottery target content to be added to the virtual box in the second replenishment is one lottery ticket A, ten items X, and 1000 100 coins. As described above, the content of the second replenishment is disadvantageous for the user as compared to the content of the first replenishment (the ratio of the lottery ticket A which is the special content (wining probability) is low). After that, whenever the number of users having the participation right increases by 1000, the same replenishment as the content of the second replenishment is performed.

  The service providing system 10 according to the present embodiment described above grants the user who satisfies the predetermined condition the lottery execution authority (participation right) for executing the time-limited lottery, and the predetermined condition is the period It becomes easier to be satisfied as time in the predetermined period in which the limited lottery is executed, and the period limited lottery is configured to be more disadvantageous to the user as time in the predetermined period passes. That is, since the number of users who can execute the time-limited lottery is small at an early point in a predetermined period and the lottery condition is relatively advantageous for the user, the user who can execute the lottery at an early point is To create a sense of speciality and to promote the early implementation of the lottery. Thus, the system 10 supports the activation of the lottery performed in a predetermined period.
