Title: Offline match making method, device, and computer-readable medium

Description:
TECHNICAL FIELD 
     The present disclosure relates to a dart game device and a dart game match making device, and more particularly, to a device for providing offline match making. 
     BACKGROUND ART 
     In general, a dart refers to a ‘small arrow’ and is a game that makes marks by throwing an arrow-shaped dart pin to a centrifugal target marked with figures. The dart game has an advantage in that anybody can enjoy the dart game anytime and anywhere if there are only an arrow headed dart and the dart target. In recent years, as various game methods have been developed and a scoring method has been organized, the dart game has been developed as worldwide leisure, therefore, all adults and children have conveniently enjoyed the dart game. 
     In general, participants of the dart game need to participate in the game at the same time and in the same space in order to enjoy the dart game. However, with development of communication technology, have been developed electronic dart game devices in which each of the participants of the dart game may remotely participate in the dart game so as to participate in the game over temporal and spatial constraints and remotely transmit a play result or a play process thereof through a communication network. The electronic dart game devices may electrically sense a hitting point of the dart target and automatically aggregate scores and provide the aggregated scores to a player. 
     However, when a plurality of dart game devices is installed in a specific space, it may be more preferable to directly play the game with a player in the same place offline than to play the game with a player positioned remotely online in terms of entertainment of the player. Therefore, when the plurality of dart game devices is preset in the specific space, a method and a device for match-making players in the same space are required so as for the players in the same space to play the electronic dart game together not online but offline.

     Advantageous Effects 
     Since it is slightly inconvenient due to resistance to rejection that players directly make conversation to propose to play a dart game together offline, there is a high possibility that the players will perform the game with another player separated therefrom online even though another player is present just next thereto. Further, although it is assumed that the players decide to play the game together through direct conversation offline in spite of the inconvenience, the players cannot but stand by until a game which is played previously ends and a dart game device to be played together needs to be determined through consultation, and as a result, additional inconvenience cannot but be present. Moreover, since a difference in skill between the players cannot be known in advance, there is a limit in increasing a fun of the game if players having a similar skill play the game together even though the players play the game together offline. 
     Therefore, the player can more easily enjoy the dart game with other player(s) there around offline through a server or a match making device according to an embodiment of the present disclosure. That is, when a plurality of dart game devices are installed in a specific space, directly playing the game with a player in the same place offline can more increase an interest and a fun of the game of the player than playing the game with a player positioned remotely online. Therefore, through a method and a device according to embodiments of the present disclosure, performing the play online or performing the play offline can be guided to be selected according to preference of the player to increase satisfaction for the game of the player and the need for match-making players in the same space can be resolved so that the players in the same space play an electronic dart game together not online but offline when the plurality of dart game devices is present in the specific space.

The components illustrated in  FIG. 1  are not essential components. Therefore, a dart game device having more components there than or less components there than may be implemented. Hereinafter, the components will be described in sequence. 
     The dart target  110  may include a score board in which a bullseye is positioned at the center and there are areas segmented by a concentric circle centering the bullseye and straight lines extended radially from the bullseye and granted with individual scores, respectively. Multiple holes into which a tip of a dart may be inserted may be deployed on the score board. 
     The dart target  110  includes a display  142  as described below to variably change score deployment of the dart target  110  and shapes of areas granted with the scores. In this case, the dart target  110  includes a light transmissive touch pad in the display  142  to be stacked to have a form of a touch screen. 
     The sensing unit  120  senses a play of a dart game player performed with respect to the dart target  110 . The sensing unit  120  may actually evaluate the play of the game player. The sensing unit  120  may sense an area of the dart target  110  which the thrown dart hits, with respect to a play in which the game player throws the dart. The sensing unit  120  electrically converts a score corresponding to the area which the dart hits to transmit the converted score to the controller  190 . 
     The player input unit  130  receives an input of a player for controlling the dart game device  100 . The player input unit  130  may include a keypad, a dome switch, a touch pad (resistive/capacitive), a jog wheel, a jog switch, and the like. The player input unit  130  may also include cameras  151  to  153 , a microphone, or the like. Additionally, the player input unit  130  may also include a short range communication module (not illustrated) as described below. In the embodiment of the present disclosure, the player input unit  130  may be configured to include the short range communication module (not illustrated) of the network connection unit  160 . When the player input unit  130  includes the short range communication module of the network connection unit  160 , the player input unit  130  may be configured to receive a user&#39;s input which is input by an external console device. As short range communication technology, Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, or the like may be used. For example, when the player input unit  130  performs the short range communication using the IrDA, the external console device may be an infrared remote controller. Alternatively, when the player input unit  130  performs the short range communication using a Bluetooth function, the external console device may be a mobile device including a Bluetooth module. The mobile device including the Bluetooth module may be, for example, a smart phone including the Bluetooth module. 
     The player may select a dart game mode, a match making request, a match approval, the number of dart game players, a dart game play mode, and the like through the player input unit  130 . For example, the player may select the number of dart game players, the dart game play mode (a zero one game, a cricket game, a count-up game, and the like), the dart game mode (a single play, a network play, and the like), the offline match making request, and the match approval through the player input unit  130 . 
     The player input unit  130  receives a signal by sensing a key operation or a touch input of the player or receives voice or a motion through the cameras  151  to  153  or the microphone of the player to convert the received signal, voice, or motion into an input signal. To this end, known speech recognition or motion recognition technologies may be used. 
     The output unit  140  which is used for generating an output related with sight, hearing, or touch may include a sound output unit  141 , a display  142 , an illumination unit  143 , and the like. 
     The sound output module  141  may output audio data received from the network connection unit  160  or stored in the memory  180  in a sound effect of the game, a game motion guide, a game method description, and the like. The sound output module  141  may also output a sound signal related with a function (e.g., a game effect sound) performed by the dart game device  100 . The sound output module  141  may also output a voice from a game player or a third person using another dart game device  200  (see  FIG. 2 ) received through the network connection unit  160 . The sound output module  141  may include a receiver, a speaker, a buzzer, and the like. Additionally, as described below, an output of a match making stand-by player list when the dart game device  100  receives an offline match making request, an output of an inquiry indicating whether to directly select an offline match opposing player, an output of an inquiry indicating whether to input a match approval of an opposing player and/or a current player, and/or an output of the dart game device designated to perform the play may be output as audio information by the sound output module  141 . 
     The display  142  displays (outputs) information processed in the dart game device  100 . For example, when the dart game device  100  is in a game play mode guidance mode, the display  142  may output a selectable game play mode. Additionally, when the dart game device  100  receives the offline match making request, the display  142  may output the match making stand-by player list. Furthermore, the display  142  may output a screen for inquiring whether to directly select the offline match opposing player and output a screen for inquiring whether to input the match approval of the opposing player and/or the current player. Moreover, the display  142  may output the dart game device designated to perform the play based on a specific algorithm. Further, when the dart game device  100  is playing the game, the display  142  may display the score sensed through the sensing unit  120  or output an image acquired by photographing the game player or the third person using another dart game device received through the network connection unit  160 . 
     The display  142  may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and a 3D display. Some of the displays may be configured as a transparent or light transmissive type to view the outside through the displays. This may be called a transparent display and a representative example of the transparent display includes a transparent OLED (TOLED), and the like. 
     In the embodiment of the present disclosure, two or more displays  142  may be present according to an implementation form of the dart game device  100 . For example, in the dart game device  100 , multiple displays may be deployed on one surface to be separated or integrally and further, deployed on different surfaces, respectively. For example, the display  142  may include both a display disposed at an upper end of the target  110  and a display disposed at a lower end of the target  110 , or may include one display thereof. However, a location where the aforementioned displays are disposed is just an example, and the displays may be disposed at various positions for a demand due to a disclosure or a visual effect. 
     A touch sensor may be configured to convert pressure applied to a specific portion of the display  142  or a change in capacitance generated at the specific portion of the display  142  into an electrical input signal. The touch sensor may be configured to detect touch pressure as well as touched location and area. When there is a touch input for the touch sensor, a signal(s) corresponding to the touch input are sent to a touch controller. The touch controller processes the signal(s) and thereafter, transmits data corresponding thereto to the controller  190 . As a result, the controller  190  may recognize which area of the display  142  is touched. 
     The illumination unit  143  outputs a signal for notifying occurrence of an event of the dart game device  100 . Examples of the event which occurs from the dart game device  100  include identification of the dart game player, direct hit of the dart, a change of the dart game player, game over, and the like. The illumination unit  143  may include a light emission diode (LED) and notify the occurrence of the event to the user through flickering of the LED. The LEDs are disposed on the bottom of the dart target  110  to be flickered according to a flickering pattern which is pre-stored according to the occurrence of the event. For example, one or more LEDs may be allocated to respective parts of the dart target  110 . The allocated LEDs are disposed on the bottom of the dart target  110  and may be disposed in a direction orienting the outside of the dart game device  100 . When the LEDs irradiate light, the light irradiated by the LEDs may pass through the dart target  110  made of a transparent or translucent material to transfer a visual output to the user. Alternatively, the light irradiated by the LEDs may transfer the visual output to the user through a gap existing in the dart target  110 . 
     The output unit  140  may also output another form other than a video signal or an audio signal, for example, a signal for notifying the occurrence of the event by vibration. 
     The camera unit  150  includes multiple cameras  151  to  153 , and as a result, an image frame processed by the cameras  151  to  1153  may be stored in the memory  180  or transmitted to the outside through the network connection unit  160 . Two or cameras  150  may be provided according to a use environment. At least some cameras of the camera unit  150  may be disposed to photograph an image frame including the dart target  110  and other cameras may be disposed to photograph an image frame directly related with a game rule in the dart game play. For example, the camera may be disposed to photograph a throw-line on which the dart is thrown in order to photograph the image frame directly related with the dart game rule. The multiple cameras  151  to  153  included in the camera unit  150  may be disposed to photograph at least some image frames to overlap with each other. In the embodiment of the present disclosure when the camera unit  150  includes one camera, the camera may be a panorama camera disposed to photograph both at least a part of the dart target  110  and the image frame (e.g., the throw-line in the dart game) directly related with the game rule. 
     The network connection unit  160  may include one or more modules that enable wireless communication between the dart game apparatus  100  and a wired/wireless communication system or between the dart game device  100  and a network on which the dart game device  100  is positioned.

     Further, the network connection unit  160  includes a short-range communication module to transmit and receive data to and from an electronic apparatus positioned in a comparatively short range from the dart game device  100  and including the short-distance communication module. As short range communication technology, Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, or the like may be used. In the embodiment of the present disclosure, the network connection unit  160  may sense a connection state of the network and a transceiving speed of the network. Data received through the network connection unit  160  may be output through the output unit  140 , stored through the memory  180 , or transmitted to other electronic apparatuses positioned in a short range through the short-range communication module. 
     Additionally, an output of a match making stand-by player list when the dart game device  100  receives an offline match making request, an output of an inquiry indicating whether to directly select an offline match opposing player, an output of an inquiry indicating whether to input a match approval of an opposing player and/or a current player, and an output of the dart game device designated to be played may be transmitted to a mobile or a PC of the player by the network connection unit  160  based on identification information of the player, and the like. 
     The player recognition unit  170  may recognize unique information of a long-range player by using a radio wave through the radio frequency identification (RFID) technology which is a kind of short range communication technology. For example, the user may possess a card, a mobile terminal, or unique dart game equipment, for example, his/her own personal dart equipment, which includes an RFID module. Information (e.g., a personal ID, an identification code, and the like of the user registered in the database server (DB) (see  FIG. 2 ) for identifying the user may be recorded in the RFID module possessed by the player. The dart game device  100  may identify the RFID module possessed by the user to identify a dart game player which plays the game by using the dart game device  100  and update a database for the identified dart game player or accumulate new data. In the embodiment of the present disclosure, the player recognition unit  170  may be integrated into the player input unit  130 . 
     The player recognition unit  170  may include various technologies (e.g., the short-range communication technology such as the Bluetooth, and the like) that may transmit and receive unique information of the user by a contact/non-contact method in addition to the RFID technology. Further, the player recognition unit  170  may include a biodata identification module that identifies biodata (a voice, a fingerprint, and a face) of the player by interworking with the microphone of the user input unit  130 , the touch pad, the camera unit  150 , and the like. 
     The memory  180  may store a program for an operation of the controller  190  therein and temporarily store input/output data (e.g., a phone book, a message, a still image, a moving picture, or the like) therein. The memory  180  may store data regarding various pattern vibrations and sounds output in the touch input on the touch screen. The memory  180  may include at least one storage medium of a flash memory type storage medium, a hard disk type storage medium, a multimedia card micro type storage medium, a card type memory (for example, an SD or XD memory, or the like), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk. The dart game device  100  may operate in connection with a web storage performing a storing function of the memory  180  on the Internet. 
     The controller  190  generally controls all operations of the dart game apparatus  100 . For example, in the case of the dart game, the score sensed through the sensing unit  120  is collected for each game participant, the collected score is transmitted to and received from another dart game device  200  connected through the network, and a game winning/losing record, the score, and the like according to the collected result are recorded. The controller  190  may perform pattern recognition processing to recognize a motion input, a writing input, and the like performed in the touch screen or the camera as a letter or an image. Further, the controller may perform speech recognition by using a speech-to-text (STT) function to recognize the speech input through the microphone as the letter. As illustrated in  FIG. 1 , since the controller  190  may communicate with all of the other components, the controller  190  may organically control operations of the components. 
     Various embodiments described herein may be implemented in a computer-readable recording medium or a recording medium readable by a device similar to the computer by using, for example, software, hardware, or a combination thereof. According to hardware implementation, the embodiment described herein may be implemented by using at least one of ASICs (application specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), processors, controllers, micro-controllers, microprocessors, and electric units for performing other functions. In some cases, the embodiments described in the specification may be implemented by the controller  190  itself. According to software implementation, embodiments such as a procedure and a function described in the specification may be implemented by separate software modules. Each of the software modules may perform one or more functions and operations described in the specification. A software code may be implemented by a software application written by an appropriate program language. The software code may be stored in the memory  180  and executed by the controller  190 . 
       FIG. 2  is a conceptual diagram of a game network  200  including a plurality of electronic dart game devices, a dart game match making device, and a server according to an embodiment of the present disclosure. As illustrated in  FIG. 2 , dart game devices C 1 , C 2 , and C 3  used by first, second, and third players P 1 , P 2 , and P 3  in a specific space, respectively may be grouped into a first group and dart game devices C 4 , C 5 , and C 6  used by fourth, fifth, and sixth players P 4 , P 5 , and P 6  in another specific space, respectively may be grouped into a second group. That is, since the respective dart game devices C 1  to C 6  have unique identification information and positional information, the respective dart game devices C 1  to C 6  may be managed by a server  209  for each identification number and/or positional information. In the embodiment of the present disclosure, the server  209  may group the dart game devices C 1  to C 6  based on the positional information and/or identification information of the respective dart game devices C 1  to C 6 . Further, although not illustrated in  FIG. 2 , the server  209  may include a media server (MS), a relay server (RS), a dart game server (GS), and a database server (DB). In the embodiment of the present disclosure, the respective dart game devices designated by reference numerals C 1  to C 6  may correspond to the dart game device  100  illustrated in  FIG. 1 . 
     As illustrated in  FIG. 2 , match making devices  206  and  207  may communicate with a first group  201  and a second group  202 , respectively through the network  200  and communicate even with the server  209 . In an additional embodiment of the present disclosure, a group  205  of the match making devices may be optional and the server  209  may substitute for a function thereof. In another embodiment of the present disclosure, the group  205  of the match making devices may substitute for functions of the server  209  to be described below. 
     In the embodiment of the present disclosure, multiple dart game players may enjoy the dart game in the same space at the same time by using the same first dart game device C 1 . However, exemplarily, when a fourth dart game player P 4  positioned at a remote range from the first dart game player P 1  intends to participate in the dart game, the fourth dart game player P 4  is connected with one or more servers  209  (the media server MS, the relay server RS, and the dart game server GS) through the network  200  by using the fourth dart game device C 4  to transmit and receive information to and from the first dart game device C 1 , thereby performing the dart game. In the embodiment of the present disclosure different dart game devices may transmit or receive information via one or more servers  209  (the media server MS, the relay server RS, and the dart game server GS) or the different dart game devices may directly transmit and receive the information there among. In an additional embodiment of the present disclosure, the dart game may be performed by differentiating places at which both dart game players P 1  and P 2  play the dart game at the same time or performed by a method in which both dart game players P 1  and P 2  play the dart game at different places at different time and winning/losing or a ranking is determined by storing play contents in the server  209  (database server). 
     The media server MS may store dart game play moving pictures of the dart game players P 1  to P 6 , which are stored by using the camera or the microphone stored in the dart game devices C 1  to C 6 . Additionally, the media server MS may be included in the DB server DB. 
     The relay server RS may perform communication among the multiple dart game devices C 1  to C 6  or connect the multiple dart game devices C 1  to C 6  and the match making device  206  and  207 .

In the embodiment of the present disclosure, the match making algorithm may be performed at least partially based on at least one of identification information, rating information, class information, point per dart (PPD) information, and mark per round (MPR) information of the current player and the opposing player as described below. Furthermore, the match making algorithm may select the opposing player for offline matching and designate a specific dart game device for playing the game together with the selected opposing player offline. The match making algorithm may designate one of a dart game device associated with the player, a dart game device associated with the opposing player, and a third idle dart game device partially based on the identification information of the player and the opposing player and the positional information of the electronic dart game device. 
       FIG. 3  is a perspective view of a dart game device according to an embodiment of the present disclosure. 
     As illustrated in  FIG. 3 , the dart game device  100  according to the embodiment of the present disclosure may be formed by mounting the components illustrated in  FIG. 1  in a housing H. A dart target  110 , a display  142 , an illumination unit  143 , a sound output unit  141 , a camera unit  150 , and a user recognition unit  160  may be disposed on the front surface of the dart game device  100 . 
     The dart target  110  may be disposed so that a dead center is positioned at a position (for example, 5 feet 8 inches in a vertical direction of the ground) suitable for a rule of the dart game. The illumination units  143 - 1 ,  143 - 2 , and  143 - 3  may be disposed at various parts of the dart game device  100  to transfer various and variable visual effects to the player of the dart game device  100 . For example, the illumination unit  143 - 1  is disposed at the side of the dart target  110  and may serve to irradiate an illumination to the dart target  110 . The illumination unit  143 - 1  may also output a predetermined illumination effect according to an event of the dart game. Further, the illumination unit  143 - 1  may output illumination effects having various colors. 
     The illumination unit  143 - 2  may be formed to be extended in a vertical direction along a forward projection of the housing H. Like the illumination unit  143 - 1 , the illumination unit  143 - 2  may output a predetermined illumination effect according to an event of the dart game and output illumination effects having various colors. 
     The illumination unit  143 - 3  may be disposed on the side of the user recognition unit  170 . The illumination unit  143 - 3  may output a predetermined illumination effect according to an event of the dart game and output illumination effects having various colors. Particularly, the illumination unit  143 - 3  may output an illumination effect for an event related with the user recognition unit  170 . 
     Selectively, the dart game device  100  may include a dart plate P which may be selectively connected with the dart game device  100  and extended in a horizontal direction. The dart plate P may further include an illumination unit  143 - 4 . The dart plate P may be integrally coupled with or selectively attached to or detached from the dart game device  100 . 
     When the dart plate P is integrally coupled with or selectively attached to the dart game device  100 , the dart plate P may be electrically connected with the dart game device  100 . The illumination unit  143 - 4  of the dart game device  100  may be disposed along the outside of the dart plate P as illustrated in  FIG. 3 . One end of the dart plate P may be extended to a place where a throw-line is to be positioned along a distance of the throw-line from the dart target according to a rule of the game. The illumination unit  143 - 4  may be disposed at a position corresponding to the throw-line. 
     Although not illustrated in  FIG. 3 , an illumination unit (not illustrated) is disposed at the bottom of the dart target  110  to irradiate an illumination effect in a user direction. The illumination unit (not illustrated) may include a combination of different illumination elements allocated according to each segment configuring the dart target. 
     The housing H of the dart game device  100  may include the display  142  disposed in the user direction. The display  142  may display information required for the user according to the progress of the dart game (for example, a collected score, information on a player during playing, a score required for clearing the corresponding game, information of an opposing player which is not playing the game, and the like). The display  142  may display a visual effect according to an event depending on the progress of the dart game. For example, when the user continuously hits a bullseye at the dead center of the dart target  100  at three dart throw chances, the display  142  may display a pre-stored motion picture corresponding to the corresponding event. The motion picture may be stored in the memory  180  of the dart game apparatus  100  or received from a server through the network connection unit  160 . 
     The display  142  may provide the user with visual and audible effects according to occurrence of the event by interlocking with the illumination units  143 - 1 ,  143 - 2 ,  143 - 3 , and  143 - 4  and the sound output unit  140 . In other words, when a predetermined event occurs, the display  142 , the illumination units  143 - 1 ,  143 - 2 ,  143 - 3 , and  143 - 4 , and the sound output unit  140  may output an illumination effect, a display effect, and a sound effect with respect to the corresponding event. 
     In  FIG. 3 , it is illustrated that the display  142  is disposed at the lower end of the dart target  110 , but the numbers and disposed positions of display  142  may be variously modified. 
     The user input unit  130  may be configured in a key pad button form as illustrated in  FIG. 3 . However, as described above, the user input unit  130  may be configured by various types including a touch screen. The user operates a key button of the user input unit  130  to select a mode of a game to be played by the user, an offline matching request and match approval and the like. 
     The sound output unit  141  is disposed on the front surface of the housing H of the dart game device  100  to output a sound. The number and disposed positions of sound output units  141  may also be variously modified. 
     The camera unit  150  may be mounted on the top of the housing H of the dart game device  100  as illustrated in  FIG. 3 . The camera unit  150  may include one or more cameras  151 ,  152 , . . . ,  153  which may photograph the dart target  110  and the throw line. The image photographed through the camera unit  150  may be transferred to the memory  180 . According to the embodiment of the present disclosure, only some of the motion pictures photographed by the camera unit  150  may be finally stored in the memory  180  or transferred to a server through the network communication unit  160 . 
     The user recognition unit  170  may be disposed on the front surface of the housing H of the dart game apparatus  100  and include a short range communication module as illustrated in  FIG. 3 . The user touches a card for recognizing the user near the user recognition unit  170  to complete user authentication. 
     The contents illustrated in  FIG. 3  and the description of the exterior of the aforementioned dart game device  100  are just an example proposed for description, and the dart game device  100  according to the present disclosure is not limited to the exterior illustrated in  FIG. 3 . 
     Hereinafter, a representative rule of the dart game and stats of the player associated therewith will be described. 
     The dart game which may be executed by the dart game device  100  according to the embodiment of the present disclosure may include a 01 game (zero-one game), a cricket game, a count-up game, a match-up mode, and the like. 
     The 01 game is performed by two teams (alternatively, two players) throwing the dart to the dart target alternately one by one round. One round includes three dart throwing operations. An object of the game is that sum-up of scores in each round reaches a target score (a score of the unit of 100 or 1000 that generally ends with 01, such as 301, 501, 701, 901, 1101, 1501 points, and the like). The target score and a play round may be arbitrarily adjusted according to the number of players that participate in the round. 
     In the cricket game, the round is performed by throwing three darts in a first round similarly to the 01 game. The standard cricket game may be performed by using only a bull region at the center of the dart target, and 20, 19, 18, 17, 16, and 15 point regions. When the corresponding cricket figures are hit with 3 marks, this is marked as a position of the player and when the corresponding cricket figures are hit with 4 marks or more, scores corresponding to the figures are added up to compete the scores. Herein, double regions and triple regions of the dart target may be calculated with 2 marks and 3 marks, respectively. While the corresponding cricket figure is marked as the position of the player, when a counterpart of the player also marks 3 cricket figures, the corresponding cricket figure is regarded to be closed and no score may be added up longer. The object of the game may be set to acquire a high score until a regulation round ends or close all cricket figures and a higher score than the counterpart. 
     The count-up game is a game at which the player wins when acquiring a high score within a predetermined round. 
     In addition to the aforementioned games, various types of games may be played by the dart game device  100  and the play mode of the dart game device  100  is not limited to the aforementioned game schemes. 
     The stats of the player may be defined according to the corresponding game rule independently from the winning or losing of the count-up game, the cricket game, and the 01 game. 
     For example, points per dart (PPD) may be calculated by dividing a total score which the player earns by the number of dart throwing times in the 01 game. Alternatively, marks per round (MPR) may be calculated by calculating the number of marking times of the player in one round. For example, in the cricket game, when the player performs three dart throwing operations in one round and the darts hit 15 triple, 19 single, and 20 double in the three dart throwing operations, respectively, the MPR becomes (3+1+2)/1=6.00 (MPR). In a subsequent round, when the player performs three dart throwing operations and the darts hit mark fail, 18 double, and 20 single in the three dart throwing operations, the MPR becomes (3+1+2+0+2+1)/2=4.5 (MPR). 
     The PPD and the MPR as the stats of the player may also be stored as personal data or identification data of the player. Alternatively, in the count-up game, an average score of the player per game, a highest score record of the player per game, and the like may be stored as the stats of the player. 
     The dart game apparatus  100  may play the dart game according to the corresponding mode and transmit a game record per player to a game server GS or a DB server DB. The game server GS or DB server DB may calculate the PPD and/or MPR for each player according to the corresponding game record and store the calculated PPD and/or MPR as accumulated PPD and/or MPR stats of the player. Further, the game server GS or the DB server DB may individually store the game record of the player. For example, in the 01 game, the count-up game, or the cricket game which the player played in the past, the game server GS or the DB server DB may record information on a segment part of a dart which the player hits each dart throwing. The game server GS or DB server DB may store accumulated (average) PPD and/or MPR data and highest PPD and/or MPR data of the player. 
     The game server GS or the DB server DB may be two physically separated servers. Alternatively, the game server GS or the DB server DB may be one physically integrated server and be distinguished according to roles performed in the server. Further, as described above, one server may serve as both the game server GS and the DB server DB. 
     The game server GS or the DB server DB may store personal stats of the player and rating (alternatively, grade (class)) may be granted to the player according to the corresponding stats. The rating and/or grade (class) which may be granted to the player according to the PPD and/or MPR may be stored as personal data or personal identification information. 
       FIG. 4  is a block diagram of a match making device according to an embodiment of the present disclosure. As illustrated in  FIG. 4 , the match making device  401  may include a receiving unit  403 , a controller  405 , an output unit  407 , a transmitting unit  409  and a memory  411 . The match making device  401  may manage a group of one or more dart game devices and communicate with a dart game device and/or a server through the transmitting unit  409  and the receiving unit  403 . 
     When an offline matching request from a player is directly input into the match making device  401  or the offline matching request is received from the dart game device of the player, the controller  405  of the match making device  401  adds identification information of a player who request match making to a match making stand-by player list to create an updated match making stand-by player list. Further, the match making device  401  may store the identification information of players and the match making stand-by player list in the memory  411 . The match making device  401  may output the updated match making stand-by player list directly by the output unit  407  or transmit the updated match making stand-by player list to a dart game device associated with the player that requests the match making by the transmitting unit  409 . When the player that requests the match making does not directly select an opposing player in the stand-by player list, the controller  405  of the match making device  401  may select the opposing player in the stand-by player list and output information associated with the selected opposing player through the output unit  407 , through a match making algorithm. In an additional embodiment of the present disclosure, the information associated with the selected opposing player may be transmitted to the dart game device associated with the player that requests the match making or the dart game device associated with the opposing player by the transmitting unit  409  of the match making device  401 . In the embodiment of the present disclosure, the match making algorithm may select the opposing player among players associated with one or more other grouped electronic dart game devices based on the electronic dart game device of the player that requests the match making and positional information. In the embodiment of the present disclosure, the match making algorithm may be performed at least partially based on at least one of the identification information, the rating information, the class information, the point per dart (PPD) information, and the mark per round (MPR) information of the current player and the opposing player as described above. Furthermore, the match making algorithm may also select the opposing player for offline matching and designate a specific dart game device for playing the game together with the selected opposing player offline. In an additional embodiment of the present disclosure, when an approval input for a match is directly received into the receiving unit  403  from players or received from dart game devices associated with the respective players, the match making algorithm may designate a dart game device which approved players will play together. In the embodiment of the present disclosure, the match making algorithm may designate one of a dart game device associated with the player, a dart game device associated with the opposing player, and a third idle dart game device partially based on the identification information of the player and the opposing player and the positional information of the electronic dart game device. As an example, the match making algorithm selects players having the most similar skill based on information of the players included in the stand-by list to perform the match making and may designate performing the play together in a dart game device associated with a player having the most excellent skill among the selected players. In an additional embodiment of the present disclosure, when an input to select an opposing player with which the current player will perform the play is received by the receiving unit  403 , the match making algorithm may perform only designation of the dart game device in which the current player performs the play together with the opposing player. Furthermore, selecting the device to play together may also be guided so that the players directly select the devices by the output unit  407  and in this case, as an example a dart game device associated with a player first input into the receiving unit  403  may be set to be selected or a dart game device selected by the player which is first input may be set to be selected. 
     When the approval input for the match and an approval input for the designated dart game device (as necessary) is directly received into the receiving unit  403  from the players or received from dart game devices associated with the respective players, the transmitting unit  409  may perform signaling so as to drive the designated electronic dart game device. When the approval input from the players is not received for a predetermined threshold time, the controller  405  may reset or cancel the match making and return to an idle state. 
     In an additional embodiment of the present disclosure, the operations of the match making device may be performed by the server. 
       FIG. 5  is a flowchart of a method for providing offline match making according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method may be performed by a dart game device. 
     The method may start in  501  and as shown in step  503 , when an input from a player is received into a player recognition unit or a player input unit, the dart game device may recognize identification information of the player. Then, when an offline match making request from the player is input ( 505 ), a match making request including identification information of the player, and the like may be transmitted to an external device ( 507 ). Herein, the external device may include a server, a dart game device, or a match making device. The external device adds the requested player to a match making stand-by player list to create an updated match making stand-by player list. The dart game device may receive the updated match making stand-by player list from the external device ( 509 ) and output the updated match making stand-by player list ( 511 ). Selectively, the dart game device may request a current player to directly select an opposing player in the match making stand-by player list ( 513 ). When the current player does not directly select the opposing player or does not request the direct selection of the player, the dart game device may receive information associated with the opposing player selected by a match making algorithm and information associated with an electronic dart game device to be played from the external device and output the information ( 515 ). Herein, the external device may transmit the information associated with the electronic dart game device to be played and information on a player which will perform a play together even to a dart game device associated with the opposing player. Then, when a match approval from players is input for a predetermined time, the process proceeds to step  519  and a current player may be finished or a stand-by time may be output for performing the play together with electronic dart game device(s) associated with the players which will perform the play together, in order to complete match making to a designated electronic dart game device. The match approval input may be an input into the dart game device associated with the respective players or an input into a dart game device designated to perform the play together. However, when the match approval from the players is not input for the predetermined time, the match making may be cancelled ( 521 ). The cancellation of the match making may be decided by the dart game device associated with the respective players or performed by receiving a cancellation command from a match making device or a server. 
     By returning to step  513 , when an input indicating that the player directly selects the opposing player is received, at least one player among the opposing players may be mapped to at least one of multiple areas constituting a dart target and the opposing player may be selected based on mapped information and hit information of the dart target ( 523 ). In other words, the dart game device may guide the current player to throw a dart to the dart target and select an opposing player mapped with a hit location based on the hit information of the dart target by the player. In this case the dart game device of the current player may transmit a play request message to the dart game device associated with the opposing player and when an approval input from the opposing player is received (from the dart game device associated with the opposing player) ( 525 ), the match making may be completed while outputting information on the dart game device designated by the match making algorithm ( 527 ). When the approval input from the opposing player is not received (alternatively, when a rejection input is received), current match making may be automatically cancelled and the process may proceed to step  515  in order to automatically select the opposing player to be played. In this case, information associated with the opposing player selected by the match making algorithm and the dart game device to be played together may be received and output from the external device ( 515 ). Subsequent steps are described as above. 
       FIG. 6  is a flowchart of a method for providing offline match making according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the method may be performed by an external device such as a match making device or a server. The match making device may manage a group of one or more dart game devices and communicate with a dart game device and/or a server through a transmitting unit and a receiving unit. 
     Now referring to  FIG. 6 , reference numeral  601  starts and when an offline matching request from a player is directly input into the match making device or the offline matching request is received from the dart game device of the player ( 603 ), a controller of the match making device adds identification information of a player who requests match making to a match making stand-by player list to create an updated match making stand-by player list ( 605 ). Then, the match making device may output the updated match making stand-by player list directly by an output unit or transmit the updated match making stand-by player list to a dart game device associated with the player that requests the match making by the transmitting unit ( 607 ). In the embodiment of the present disclosure, the updated match making stand-by player list is output, and as a result, the match making device may guide the player which request the match making to select an opposing player among players in the match making stand-by player list ( 609 ). 
     When the player which requests the match making does not select the opposing player in the stand-by player list for a specific time(alternatively when an input not to select the opposing player is received into the match making device), the controller of the match making device may select the opposing player in the stand-by player list and/or designate a dart game device to be played together and output the information or transmit the information to the dart game device, through a match making algorithm ( 611 ). In this case, when a match approval is directly input from players for a predetermined threshold time or received from the dart game device ( 613 ), the match making device may perform signaling to the designated electronic dart game device so as for the players to perform a play while completing match making to the designated electronic dart game device ( 615 ). If not ( 613 ), the match making device may cancel the match making ( 617 ). In an additional embodiment of the present disclosure, when the match making is cancelled, the match making device may select another player together through the match making algorithm. 
     When an input to directly select the opposing player in the stand-by player list is received from the player which requests the match making, the match making device may transmit a play request to a dart game device associated with the opposing player ( 619 ). Then, when the approval input from the opposing player is received ( 621 ), the dart game device to be played together is designated and output through the match making algorithm or information associated with the dart game device associated with the opposing player and the dart game device designated as the dart game device associated with the requested player may be transmitted ( 623 ). If not ( 621 ), the match making device may cancel the match making ( 625 ) and the process proceeds to step  611  to select the opposing player to perform the play and the dart game device to be played by automatically performing the match making algorithm. Subsequent steps are described as above. 
     In the embodiment of the present disclosure the match making algorithm may select the opposing player among players associated with one or more other grouped electronic dart game devices based on the electronic dart game device of the player that requests the match making and positional information. In the embodiment of the present disclosure, the match making algorithm may be performed at least partially based on at least one of the identification information, the rating information, the class information, the PPD information, and the MPR information of the current player which requests the match making and the opposing player. Furthermore, the match making algorithm may not only select the opposing player for offline matching but also designate a specific dart game device for playing the game together with the selected opposing player offline. In the embodiment of the present disclosure, the match making algorithm may designate one of a dart game device associated with the player which requests the match making, a dart game device associated with the opposing player, and a third idle dart game device partially based on the identification information of the player which requests the match making and the opposing player and the positional information of the electronic dart game device.
