     DETAILED DESCRIPTION OF THE INVENTION 
     The following description is given of specific embodiments of the present disclosure with reference to the attached drawings. 
     The following embodiments are to be construed in all aspects as illustrative and not restrictive. The scope of the present disclosure should be determined by the appended claims and their legal equivalents, not by the following description, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein. Like reference numerals denote the same or similar components in many aspects in the drawings. 
     With reference to the accompanying drawings, various embodiments of the present disclosure will be described below in detail so that those skilled in the art may readily implement the present disclosure. 
       FIG. 1  is a schematic view illustrating a game chance-based product advertisement system according to an embodiment of the present disclosure. 
     Referring to  FIG. 1 , the game chance-based product advertisement system according to the embodiment of the present disclosure may include a service server  100 , a user terminal  200 , and a product registrant terminal  300 . 
     The service server  100  illustrated in  FIG. 1  receives product information from a product registrant, determines game chance information based on the product information, sets users as subscribers to a game chance by receiving subscription requests for the game chance from the users, provides a game to the game subscribers at the starting time of a game, and determines a reward recipient and a reward type based on user rankings in the game. 
     Recently, many techniques have been used to promote sales of products in the mobile shopping market. One of major product advertisements is a banner ad which inserts a banner including an image or text describing a product in a predetermined area of a user-loaded page, and moves the user to a detailed page for the product, when the user clicks on the banner. However, such banner ads lead to a lot of meaningless selections and are exposed indiscriminately to an unspecified number of customers with no interest in products, thus causing high cost. 
     To solve problems of the conventional advertisement method, a game chance-based product advertisement method according to an embodiment of the present disclosure provides information about an advertised product to users, along with a game chance associated with the advertised product. Thus, a user will pay more attention to information about the product in order to subscribe to the game chance. Further, the user is exposed to the product information for a longer time, and the user&#39;s attention to the product information is increased. As a result, a high advertisement effect may be achieved with low cost. From the viewpoint of the user, if the user ranks high in the free game chance, the user may get a free coupon or discount for the advertised product. Further, since a product registrant intending to promote the sales of the product may pay an advertisement fee by the advertised product or a discount coupon for the advertised product, the product registrant may reduce advertisement cost. 
     According to an embodiment of the present disclosure, the product registrant terminal  300  may register a product to be advertised to the service server  100 . While only a single product registrant terminal  300  is shown in  FIG. 1 , it is obvious that a plurality of product registrant terminals  300  may register a plurality of products. The product registrant terminal  300  may transmit product information to the service server  100  in order to register the product. 
     According to an embodiment of the present disclosure, the user terminal  200  includes a mobile device and a personal computer (PC). The user terminal  200  may include a display capable of displaying a mobile page or a Web page provided by the service server  100 . A user may participate in a game chance provided by the service server  100  and play a game, using the user terminal  200 . 
     Meanwhile, a communication network  400  serves to connect the user terminal  200  and the product registrant terminal  300  to the service server  100 . That is, the communication network  400  refers to a communication network that provides a connection path in which the user terminal  200  and the product registrant terminal  300  access the service server  100  and then transmit and receive data to and from the service server  100 . That is, the communication network  400  according to an embodiment of the present disclosure may be configured irrespective of a communication type such as wired communication or wireless communication. 
     Hereinbelow, an action of a terminal may be described as an action of a subject using the terminal, for the convenience of description. For example, an action of the product registrant terminal  300  may be described as an action of a subject using the product registrant terminal  300 , that is, a product registrant. For example, reception of product information from the product registrant may be understood as receiving the product information from the product registrant terminal  300 . 
     Now, the present disclosure will be described, focusing on the internal structure of the service server  100 . 
       FIG. 2  is a block diagram illustrating an internal structure of a service server according to an embodiment of the present disclosure. 
     Referring to  FIG. 2 , the service server  100  according to the embodiment of the present disclosure includes a product information acquirer  110 , a game chance decider  120 , an advertisement fee calculator  130 , a game chance display  140 , a game subscriber decider  150 , a game player  160 , a reward provider  170 , a survey chance unit  180 , and a social networking service (SNS) manager  190 . 
     First, the product information acquirer  110  acquires product information about an advertised product from the product registrant terminal  300 . The product information may be data such as text, an image, a video, or a sound related to the product that the product registrant wants to advertise. Additionally, the product information may include information specifying a time at which a product seller wants to provide a game chance, the number of game chances, the number and discount rate of products available in the game chances, a game used in the game chances, and so on. 
     More specifically, the product registrant may select a game optimized for the product to be advertised. Game types available to the product registrant may include a game that selects a winner randomly, a game of competing in ability such as quickness or memory, and so on, and the product registrant may select a game in consideration of a product image and product features. 
     In a specific example of the present disclosure, if the product registrant wants to advertise ‘gloves’, the product information acquirer  110  may acquire image data describing the gloves from the product registrant terminal  300 . Additionally, the product information acquirer  110  may acquire information about a desired game starting time, a game type, a reward winner, and a reward type in relation to a game chance for the gloves from the product registrant terminal  300 . For example, the product registrant may register information indicating free offer of the advertised product, gloves to a first-place winner in the game to the product information acquirer  110 . 
     Additionally, when the product registrant registers product information, the product advertisement system of the present disclosure may provide the product registrant with additional information indicating which goods are better for selection by a customer survey function. Further, the product registrant may first upload game chances to the service server  100  and thus select a product having a high degree of participation. For example, if the product registrant has not decided what product to sell yet, the product registrant may first create game chances, and register the game chances to the product advertisement system. After observing for what products users consume their cyber points, the product registrant may acquire information about preferences for the products. As described later, since the number of cyber points that a user may use in one day to participate in a game chance is limited, the user has to carefully participate in each game chance. Therefore, a product corresponding to a game chance that users have selected relatively often means a product for which users have demonstrated high preference. Additionally, the product registrant may receive information about a product with a high user preference by a customer survey chance. 
     Then, the game chance decider  120  creates a game chance for the advertised product based on the product information acquired by the product information acquirer  110 , and determines a game starting time, a game type, a reward winner, and a reward type for the game chance. Herein, the game chance decider  120  may generate a plurality of game chances for a single advertised product. Further, the game chance decider  120  may control the game starting time of one game chance not to coincide with the game starting time of another game chance. The game type of the game chance may have a time restriction, and games executable in the user terminal  200  may be used without restriction. The reward winner is information about up to what ranking a reward is to be offered, and the reward type is information about the type of a reward that the reward winner is to receive. In an embodiment of the present disclosure, the game chance decider  120  may determine the reward winner and the reward type to be the advertised product for a first-place winner and a discount coupon for the advertised product for a second-place winner. 
     With continued reference to the specific example of the present disclosure, the game chance decider  120  may create a game chance for the advertised product, gloves, set a game starting time for the game chance as 2:00 pm, set a game type as a card turnover game, set first-place, second-place, and third-place winners in the game as reward winners, and set reward types as gloves for the first-place winner, a 70% off coupon for a purchase of gloves for the second-place winner, and a 30% off coupon for a purchase of gloves for the third-place winner. 
     Further, according to an embodiment of the present disclosure, the game chance decider  120  may enable the product registrant to autonomously create a game chance. More specifically, although an advertiser, a seller, and a small business owner have no additional marketing means, they may create and expose a game chance autonomously in the advertisement method according to the embodiment of the present disclosure. For example, if the product registrant selects a product that the product registrant sells, enters a discount rate, selects a game, selects a time, and requests a game chance, a new game chance may be opened and users may participate in the game chance. That is, if the product registrant such as an advertisement agent or a seller directly selects an exposure time zone, a game, and a discount rate by means of the product registrant terminal  300 , a game chance for the product may be exposed in an application of the present disclosure. 
     Subsequently, the advertisement fee calculator  130  may calculate an advertisement fee that the product registrant is to pay for the advertised product. According to an embodiment of the present disclosure, the advertisement fee calculator  130  may calculate the advertisement fee that the product registrant is to pay for the advertisement of the product as a reward offered in the game chance according to a request of the product registrant terminal  300 , so that the product registrant may pay the advertisement product as promotion goods of the game chance for the advertisement of the product, instead of an advertisement fee. For example, the product registrant may pay gloves which are to be offered as a reward from a game chance, as an advertisement fee in return for the service of the present disclosure. Additionally or alternatively, the product registrant may pay a discount coupon for a purchase of gloves, which will be offered as a reward from the game chance, as an advertisement fee. 
     Further, the advertisement fee calculator  130  may automatically calculate an advertisement fee in consideration of an exposure time of a game chance, a game starting time, the number of participants in a previous game chance, and a purchase conversion rate of the game chance. For example, there may be a popular time zone in which users are concentrated, such as 10:00 to 12:00 am on weekends, and a high advertisement fee may be set for a game chance in this popular time zone. More specifically, once a desired time zone is selected, an advertisement fee for the time zone may be automatically calculated, and the advertisement fee of a peak time zone may be set to double the advertisement fee of a standard time zone. 
     For this purpose, to enable the advertisement fee calculator  130  to automatically calculate an advertisement fee when the product registrant registers product information, weights may be assigned to references including an exposure time of a game chance, a game starting time, the number of participants in a previous game chance, and a purchase conversion rate of the game chance, depending on how much the references affect the advertisement fee. 
     In another embodiment of the present disclosure, the advertisement fee calculator  130  calculates an advertisement charge on a time zone basis. The advertisement fee calculator  130  calculates a default price according to the average number of subscribers for the past three months, the average number of real participants, an average purchase rate, and per-business type features, a final price is set in a bid starting from the default price, and a product registrant who has entered a highest bid price becomes a successful bidder. Thus, a game chance for the successful bidder is exposed in the corresponding time zone. 
     Then, the game chance display  140  may provide the user terminal  200  with information about the start of a game in a game chance and information about the advertised product corresponding to the game chance. That is, the game chance display  140  may provide information about the game chance and the product information to the user terminal  200 . More specifically, the game chance display  140  may generate a game chance table per time for a plurality of game chances. When a user selects one game chance in the displayed game chance table, the game chance display  140  may provide detailed information about an advertised product corresponding to the game chance. Herein, the game chance display  140  may make up a game chance table by arranging game chances in the order of earlier game starting times. According to an embodiment of the present disclosure, as product information is displayed together with information about a game chance, the advertisement effect for a product may be primarily achieved. 
       FIG. 3  is an exemplary view illustrating the user terminal  200  which displays a game chance table generated according to an embodiment of the present disclosure. 
     Referring to  FIG. 3 , a game chance table listing game chances for products A, B and C is displayed on the user terminal  200 . More specifically, it may be noted that a game starts at  13 : 00  in a game chance for product A and a reward type is a free offer of a 29000-won product. If a user selects the game chance on the display of the terminal, a screen containing detailed information about product A may be displayed. With continued reference to the specific example of the present disclosure, product A may be gloves, and the reward type may be a free offer of gloves to a first-place winner in the game. 
     Additionally, according to an embodiment of the present disclosure, the game chance display  140  may display recommended game chances in consideration of tastes of the user. For example, a customized advertisement for a game chance may be automatically displayed on a personal home page of the user, or a recommended game chance may be automatically displayed according to the contents of a subscription by analyzing data about selections or subscriptions that the user has previously made. 
     Subsequently, the game subscriber decider  150  receives a subscription request for a game chance from the user terminal  200 , and adds the user of the user terminal  200  to a subscriber list for the game chance. That is, the game subscriber decider  150  completes a subscriber list for each game chance. Herein, the game subscriber decider  150  receives subscription requests for the game chance from user terminals  200  until shortly before the starting time of the game chance, and completes a subscriber list for the game chance shortly before the starting time of the game chance. With continued reference to the specific example of the present disclosure, the game subscriber decider  150  may add a user requesting subscription to a subscriber list for the game chance for gloves. 
     In an embodiment of the present disclosure, only when a user requesting subscription to a game fulfills a predetermined qualification, the game subscriber decider  150  may add the user to the subscriber list. In an embodiment of the present disclosure, only when one or more detailed pages for the advertised product of the game chance are displayed on the user terminal  200 , the game subscriber decider  150  may add the user to the subscriber list. That is, although it is typical that users often do not view all of the contents of an advertisement, a user needs to display all of advertisement pages to participate in a game chance according to the present disclosure. Therefore, the advertisement effect may be increased. 
     In an embodiment of the present disclosure, the number of game chances in which a user can participate in one day may be limited. In an embodiment of the present disclosure, a user may have three game chance subscription opportunities in one day. If the user uses up the three game chance subscription opportunities, the user may not be added to a subscriber list for any other game chance. Only a predetermined number of game chance subscription opportunities for one day may be offered to the user as cyber points. For example, if cyber points for subscription to a game chance are referred to as ‘pumpkins’, three pumpkins may be provided to a user every day. Each time the user participates in a game chance once, one pumpkin is used up. If all of the pumpkins are used up, the user is not allowed to participate in a game chance any further. This is intended to induce a user to obtain information about a product fully and then participate in a game chance, to thereby prevent indiscriminate participation in a game chance. As a consequence, the advertisement effect of a product may be increased. 
     In conventional advertisement methods, an advertisement is unconditionally exposed to users irrespective of preferences of the users. Therefore, an advertisement effect is low with respect to an advertisement expenditure. On the contrary, a user&#39;s selection of a game amounts to selection of an advertisement to be exposed in the advertisement method of the present disclosure. Therefore, if a user selects a game to play with limited cyber points, the effect of selecting an advertisement to be exposed by the user results. For example, since a user having three opportunities to subscribe to game chances will subscribe to game chances for products or product fields in which the user is interested by the limited subscription opportunities, the advertisement effect may be maximized. Further, if the number of opportunities to subscribe to game chances is limited as described above, a product that each user prefers may be determined. Thus, a highly preferred advertisement may be exposed in an area with a high preference per user by collecting interests of users in a customized manner. 
     Further, according to an embodiment of the present disclosure, the game subscriber decider  150  may transmit an alarm to user terminals  200  placed on a subscriber list a predetermined time before the starting time of a game in a game chance. That is, the game subscriber decider  150  may transmit a push message to game subscribers. Herein, if an advertisement of a product or a service is inserted in the push message, the desire for purchasing the product or service may be increased. Further, if a reward such as a coupon is offered to a user that has clicked on the push message, the advertisement message may have diversified functions. 
     For example, if 5 minutes are away from the starting time of the game in the game chance for gloves, the game subscriber decider  150  may notify the users listed on the subscriber list that only 5 minutes remain before the starting time of the game. Herein, the alarm transmitted by the game subscriber decider  150  may include a message asking a user whether the user will enter a game waiting room. 
     Further, according to an embodiment of the present disclosure, the game subscriber decider  150  may receive waiting room entry requests from users listed on the subscriber list, and admit the users to the waiting room. Information about the advertised product in the game chance may be displayed again in the game waiting room. Thus, the users view the product information once again during a game waiting time, thereby increasing the advertisement effect. 
       FIG. 4  is an exemplary view illustrating a game waiting room according to an embodiment of the present disclosure. 
       FIG. 4  is a view illustrating a screen of a game subscriber which has entered a game waiting room of a game chance. More specifically, according to an embodiment of the present disclosure, if the user selects the game chance for product A in the game chance table of  FIG. 3 , displays all of detailed pages describing product A, and then requests subscription to the game chance and admission to the game waiting room, such a screen as illustrated in  FIG. 4  may be displayed on the user terminal  200 . Herein, a time left until a game starts and advertised product information may be displayed in the game waiting room, as illustrated in  FIG. 4 . 
     Subsequently, the game player  160  provides a game to the game subscribers listed on the subscriber list for the game chance at the game starting time of the game chance. With continued reference to the specific example of the present disclosure, the same card matching game may be provided to user terminals  200  listed on the subscriber list of the game chance at the starting time of the game chance for gloves, 1:00 PM. 
     Only when the user terminal  200  enters the waiting room of the game chance, the game of the game chance may be played on the user terminal  200 . That is, only when the user connects to the waiting room for the game chance before the start of the game, the user may participate in the game. The game may be automatically played at the predetermined starting time of the game for the users which have entered the waiting room of the game chance. Even though a user has been registered to the subscriber list, unless the user terminal  200  of the user connects to the waiting room of the game chance at the game starting time, the game of the game chance may not be provided to the user. Further, if the game starting time has elapsed, even a subscriber placed on the subscriber list may not participate in the game. 
     Further, the game player  160  according to an embodiment of the present disclosure may allow a user terminal which has not downloaded the application of the product advertisement system of the present disclosure to play the game. For example, if a game subscriber shows a product to another user by a mobile Web in order to share a game to which the game subscriber has subscribed, the other user may first play the game without the application, and view the result of the game chance by downloading the application. 
     Further, the game player  160  according to an embodiment of the present disclosure may provide product information on a game screen while the user is playing the game. That is, when the user selects the game, the product information may be primarily exposed, and when the game is played, the product information may be secondarily exposed. Therefore, the advertisement effect may be achieved. 
     Then, the reward provider  170  determines rankings in the game by collecting the play results of the game, and determines a reward recipient and a reward type for the game chance based on the rankings. The rankings may be rankings of scores that the game players have achieved in the game, or rankings of players which have finished the game earlier. As described before, the game chance decider  120  may determine a reward winner and a reward type for the game chance. The reward provider  170  may determine a user of a determined ranking in the game to be the reward winner and determine to offer a reward to the user. 
     With continued reference to the specific example of the present disclosure, the reward winner and reward type for the game chance of gloves may be a free offer of gloves to a first-place winner, an offer of a 70% off coupon for a purchase of gloves to a second-place winner, and an offer of a 50% off coupon for a purchase of gloves to a third-place winner. The reward provider  170  may select the first-place winner, the second-place winner, and the third-place winner as reward recipients, and transmit information about the reward types to the reward winners. 
     Further, in a selective embodiment of the present disclosure, the reward provider  170  may offer a reward only when a reward recipient uses the reward immediately, simultaneously with reception of reward information. That is, the reward provider  170  may prompt the reward recipient to use the reward immediately, while notifying the reward recipient of the reward. If the reward winner does not use the reward immediately, the reward may be cancelled. This is intended to increase a product purchase probability as well as to fast notify a reward offer. 
     Further, according to an embodiment of the present disclosure, the reward provider  170  may determine a reward winner in a different manner according to a game. With continued reference to the specific example of the present disclosure, the reward provider  170  may randomly select 10 users from among top 100 players of a game, and determines the selected 10 users as reward recipients. In another example, the reward provider  170  may select players ranked in the first, tenth, and 100 th  places, and determine the selected players as reward recipients. In a further example, the reward provider  170  may select players randomly from among total players of the game irrespective of their scores, and determine the selected players as reward recipients. 
     Further, according to an embodiment of the present disclosure, the reward provider  170  may provide product information along with information about a reward to a user. That is, when the user selects a game, product information is primarily exposed, when the user plays the game, the product information is secondarily exposed, and when a reward is offered to the user, the product information is finally provided. Thus, the advertisement effect may be achieved. 
     Further, in the specific example of the present disclosure, at the same time when the first-place winner of the game is notified of a reward, the first-place winner may be prompted to enter an address to which the reward, that is, free gloves are to be delivered. At the same time when the second-place winner of the game is notified of a reward, the second-place winner may be prompted to purchase gloves with a 70% off coupon. If the first-place winner or the second-place winner does not use the reward immediately, the reward may be cancelled. That is, the present disclosure may offer different rewards regarding purchase of goods or services according to the game scores of users which have participated in a game chance. The different rewards may be provided in a time-sale manner so that upon timeout of a predetermined time, the reward may be expired. Further, a discount coupon may be provided as a reward to every participant in a game chance. That is, the advertisement system according to an embodiment of the present disclosure may offer a discount coupon treated like cash as a reward to a user which has viewed and participated in or subscribed to a game, instead of offering points to a user which just views an advertisement. As a consequence, the advertisement effect may be increased. 
       FIG. 5  is an exemplary view illustrating the user terminal  200  displaying game results according to an embodiment of the present disclosure. 
     In  FIG. 5 , a screen displayable on the user terminal  200  of a first-place winner in a game, user a is shown, by way of example. Referring to  FIG. 5 , the reward provider  170  may display a screen announcing the results of the game. Further, if the first-place winner of the game is a reward winner, the reward provider  170  may determine user a winning in the first place in the game as a reward recipient and receive an address to which product A being a reward type will be delivered for free. As described before, according to an embodiment of the present disclosure, if a reward is not used upon announcement of the reward, the reward may be cancelled. 
     Additionally, the advertisement system according to an embodiment of the present disclosure may provide a function of communication between users regarding a game chance. For example, users may share information about a product or a game chance by managing a home page using an SNS function, opening a chatting window, or writing a reply on a product page in the product advertisement system of the present disclosure. Since users selecting the same game chance are highly likely to have common interest, the users are allowed to talk with each other by the SNS function, to thereby exchange information about goods or a service. Further, a user achieving a high score in the above-described style chance may be allowed to create content about the product or the game chance on his or her own. 
     Referring to  FIG. 2  again, the survey chance unit  180  includes a survey product selector  181 , a preference score collector  182 , a winner selector  183 , and a winner reward decider  184 . The survey chance unit  180  is a component for providing a survey chance service of the present disclosure. The survey chance service is a service of conducting a survey of users&#39; preferences for a product and offering a reward to a survey winner that has entered a preference closest to the average preference of the product. 
     More specifically, the survey product selector  181  selects a product selected by a product registrant as a survey product. The product registrant may be an advertiser, and one or more products may be selected as survey products in each category (e.g., clothes, home appliances, offline tickets, and so on). The survey product selector  181  selects, arranges, and provides one or more survey products per product category. The survey products may be arranged based on current preference scores of the survey products. 
     According to another embodiment of the present disclosure, the survey product selector  181  may select a product selected based on a user request as a survey product. For example, if three or more product purchasers request registration of a specific product as a survey product, the survey product selector  181  may select the product as a survey product without receiving a request from a product registrant. 
     Additionally or alternatively, the survey product selector  181  may select survey products so that products selected by a product registrant and products selected by users may become survey products at a predetermined ratio. For example, the survey product selector  181  may select one half of survey products from products selected by a product registrant and the other half of the survey products from products selected by users. 
     Then, the preference score collector  182  collects preference scores for a survey product from a plurality of survey participants among users. That is, users may enter their preference scores for the survey product in a survey created for the survey product, and the preference score collector  182  collects the preference scores of the plurality of survey participants. 
       FIG. 6  is an exemplary view illustrating a user terminal which displays a screen for collecting preference scores according to an embodiment of the present disclosure. 
     Referring to  FIG. 6 , a message prompting a user to enter a preference score for a specific item may be displayed, and the user may enter or select his or her preference score for the item. In the embodiment of  FIG. 6 , it is noted that the user has entered a preference score of 6.0 for the item. In this method, the preference score collector  182  collects preference scores entered by users. 
     Further, the preference score collector  182  according to an embodiment of the present disclosure may arrange the collected preference scores by gender, age, and purchase history, and provide the arranged preference scores. Further, the preference score collector  182  according to an embodiment of the present disclosure may provide a product registrant of a notification recommending registration of a game chance of the present disclosure for a highly preferred survey product. 
     Herein, the preference score collector  182  may collect only the preference scores of users having cyber points. That is, only users having cyber points may enter preference scores in a survey chance, and a predetermined number of cyber points for one day or cyber points corresponding to a predetermined money amount for one day may be given to the users. For example, only cyber points with which to participate in five survey chances per day may be provided to users. 
     Subsequently, the winner selector  183  calculates the average of the collected preference scores, and selects one or more winners based on the average. Herein a winner may be a user which has entered a preference score closest to the average preference score. One or more winners may be selected according to a setting. For example, if the average of preference scores entered by a plurality of users is 5.5, user a has entered 5.3, and user b has entered 5.6, user a may be a winner. Meanwhile, if one winner is set and the deviations of the preference scores entered by two or more users from the average of the preference scores are equal, like the case where user a has entered 5.3 and user has entered 5.7, user b which has entered the higher preference score may be selected as the winner. Further, if a survey is conducted for a plurality of successive survey products, a user which has entered a preference score closest to the average of preference scores for the first survey product may be selected as a winner. 
       FIG. 7  is an exemplary view illustrating a user terminal which displays survey results according to an embodiment of the present disclosure. 
     Referring to  FIG. 7 , the results of a survey are displayed on a user terminal. In the embodiment of  FIG. 7 , it may be noted that the average of preference scores collected for the specific product in the embodiment of  FIG. 6  is 5.5. Further, users are ranked based on the average preference score, and as noted from  FIG. 7 , user a and user b are ranked sequentially in the first and second places in the order of closeness to the average preference score. Therefore, the winner selector  183  may select user a as the winner of the survey chance for the corresponding product. In an embodiment of the present disclosure, the winner of the survey chance may be referred to as a ‘stylist’. 
     Then, the reward decider  184  may determine a reward to be granted to the winner. According to an embodiment of the present disclosure, a user having a preference score closest to the average of the preference scores of users for a survey product may be rewarded. For example, a free coupon or a discount coupon for the survey product may be provided to the winner. The product registrant (advertiser) may use the style survey service of the present disclosure by supporting a free coupon or a discount coupon to be provided to the survey winner. Additionally or alternatively, besides the winner, the reward provider  184  may provide a discount reward to a predetermined number of users in the order of closeness to the average preference score. 
     According to an embodiment of the present disclosure, the reward decider  184  may limit a reward validity time. For example, the reward decider  184  may provide a discount coupon valid only during 24 hours to the winner after the survey ends, and notify the winner of cancellation of the reward after the limited time. 
     With continued reference to  FIG. 2 , the SNS manager  190  may provide an SNS account to each user. The user may register his or her interested product through the SNS account provided to the user, and share information with other users. 
     More specifically, the SNS manager  190  according to an embodiment of the present disclosure may register other users which have participated as SNS acquaintances of users in the same game chance or survey chance. Thus, a group of users having similar interests formed through a game chance or survey chance, or participants in the game change or survey chance may advantageously engage in their own social activities. 
     Further, the SNS manager  190  according to an embodiment of the present disclosure may automatically register participants in a survey chance as followers of a survey winner. Additionally or alternatively, the SNS manager  190  according to an embodiment of the present disclosure may register participants in a game chance as followers of a winner of the game chance. 
     Further, the SNS manager  190  according to an embodiment of the present disclosure may derive interests of users based on limited cyber points of the users, referring to game chances or survey chances selected by the users, and recommend SNS acquaintances based on the derived interests. As described before, users may participate in a game chance or survey chance, using a limited number of cyber points. For example, even though 30 game chances are created per day, if cyber points available only for five game chances are given to each user, game chances selected by the user may be considered as reflecting interests of the user. Therefore, the SNS manager  190  according to an embodiment of the present disclosure may determine interests of a user based on game chances or survey chances selected by the user, and establish an SNS acquaintance relationship between users having the same interests. 
     Further, the SNS manager  190  according to an embodiment of the present disclosure may provide a platform on which a user may autonomously create a game chance own and register the game chance to the user&#39;s SNS page. That is, according to an embodiment of the present disclosure, a product or service seller may create a game chance directly. Herein, an SNS page of a user may refer to a home page corresponding to a user account, or a Web page of a personal account such as Facebook, Instagram, or a blog. More specifically, a user may create a game chance by primarily selecting a product or service to be advertised, secondarily selecting a game type, and then determining a reward and selecting a method for rewarding a game participant (e.g., whether to reward only a first-place winner or a randomly selected one of game participants). Further, the SNS manager  190  according to an embodiment of the present disclosure may set a specific amount of money for a voucher for creating a game chance. 
     For example, the user may purchase a voucher for creating 10 game chances for 30,000 won for one month. As described before, the user which has purchased the voucher may post a game chance generated by setting product information, a reward, a game type, and the number of game participants on the user&#39;s SNS page. Other users may get a discount coupon after selecting the game chance posted on the SNS page of the user and playing a game. Therefore, the product seller may achieve a high advertisement effect with respect to marketing cost. 
     Further, the SNS manager  190  according to an embodiment of the present disclosure may enable the user which has created the game chance to invite the user&#39;s acquaintances to a game room for the game chance. Herein, the SNS manager  190  may impose a condition that an admission fee is to be paid to enter the game room, according to an input of the user. In this case, the admission profit may be used to reward a winner in the game room, for example, as cost to be expended to offer an advertised product. 
     Further, the SNS manager  190  according to an embodiment of the present disclosure may post information about a survey product on an SNS page of a user selected as a survey winner. For example, the SNS manager  190  may post information about the survey product in the survey and information indicating that the user has been selected as the winner of the survey on the home page of the user selected as the survey winner. Further, the information about the survey product posted by the SNS manager  190  may include a link to a shopping site in which the product is available. If the survey product is purchased via the link, the SNS manager  190  may determine to allocate a part of the profit to the user corresponding to the home page account. 
     Additionally, the SNS manager  190  provides an SNS platform on which the user selected as the survey winner may provide mobile broadcasting as a shopping host for the survey product. Thus, while advertisement traffic is secured for the survey product, the survey winner may engage in creative activities and make profit, and other users may easily determine whether to purchase the survey product and enjoy convenient shopping, referring to product contents created and posted on the home page by the survey winner. 
       FIG. 8  is an exemplary view of an SNS page of a user according to an embodiment of the present disclosure. 
     Referring to  FIG. 8 , an SNS page of a user called TOM is shown. As described before, according to an embodiment of the present disclosure, product information in a survey chance in which a user has been selected as a survey winner may be displayed on an SNS page of the user. In the embodiment of  FIG. 8 , the survey winner may be referred to as a ‘stylist’, and a list of survey products for which the user has been selected as a survey winner and information about the survey products (pictures of the products in the embodiment of  FIG. 8 ) may be displayed under ‘stylist&#39;s picked items’. When a user selects product information displayed under the stylist&#39;s picked items, the user may move to a shopping site selling a corresponding product. That is, according to the embodiment of  FIG. 8 , the user TOM has been selected as a survey winner in survey chances for the items displayed under the ‘stylist&#39;s picked items’, and other users may select a link to a displayed item and move to a shopping site selling the item. Thus, other users may be aware that the user TOM is a user having preferences closest to the preferences of the displayed survey products. Further, other users may move to a shopping site in which a product is purchasable by selecting a link to the survey product. Herein, if another user purchases a survey product by selecting a link, a predetermined ratio of the purchase amount may be paid to the user of the page (the user TOM in the embodiment of  FIG. 8 ). 
     As is apparent from the foregoing description, according to the present disclosure, as a survey for collecting preference scores for a product is created, a meaningful evaluation of users may be provided to a product registrant. 
     According to the present disclosure, since a reward is offered to a survey winner which has entered a preference score closest to an average preference score for a product, users are motivated to enter preferences. 
     According to the present disclosure, the reliability of a survey winner regarding product evaluation may be increased by providing information about a survey product on an SNS page of the survey winner.
