Description

RECORDING MEDIUM RECORDED WITH PROGRAM FOR BATTLE BOARD GAME UTILIZING BADUK RULES AND SYSTEM AND METHOD FOR ON-LINE BATTLE BOARD

GAME UTILIZING BADUK RULES Technical Field

[1] The present invention relates to a recording medium recorded with a program for a board game utilizing baduk rules and a system and method for an on-line battle board game utilizing baduk rules. According to the board game, a map having M x N intersections in which M horizontal lines and N vertical lines intersect are provided, and two sets of stones with each set having a different color are used. In addition to general baduk rules, rules such as simultaneous opening placements of stones at multiple intersections, deom (extra compensation) betting, intersections which each have a different set score, stones which each have a different set score, and hidden stones that can be used without opponent's awareness are further included. Instead of score counting, the score of intersections and the score of stones appearing at the time when a stone is placed are added and a game player having a highest final score which is displayed in real-time is determined to be a winner. In this way, even a person who does not know baduk rules well can easily learn the baduk rules and play a game or watch games in progress. The game is not a violent one and everyone from children to adults can enjoy the game. Since the game playing time becomes relatively shorter, players can play the game without time pressure. The game also provides funs of a variety of reversals. Background Art

[2] Baduk is the best strategy game on earth that has been played for thousands of years.

General Baduk rules are as follows. On a baduk board having 19 horizontal lines and 19 vertical lines, a player having white stones and a player having black stones alternately place each one of white and black stones on the intersections at which the vertical lines and the horizontal lines intersect. In the off-line game, a person securing a bigger territory (intersections surrounded by white stones only or black stones only) wins at the end of the game. Only with a baduk board and baduk stones, players can enjoy the game regardless of time and place, and a variety of strategies can be executed based on high-level mathematical and scientific thinking and artistry. Accordingly, the game has favorable effects on making good use of spare time and mental health for adults as well as development of brain and cultivation of human nature for growing children. [3]

[4] Nevertheless, since it takes much time to finish one baduk game, it is difficult to enjoy the game by utilizing a short spare time, and it also takes much time to watch others playing a baduk game. Stereotyped formulas and playing games based on the formulas may be boring. Accordingly, the baduk game has been unable to attract attention of growing children or most of teens and adults who like computer games.

[5] In addition, in order to learn baduk for the first time, many established patterns

(formulas) together with complicated rules should be memorized and therefore much time should be invested in order to reach a level for enjoying baduk. Accordingly, despite the favorable effects, it has been difficult to expand the base of the baduk population, and actually even in Korea which is referred to as a strong baduk country, the baduk population has rapidly decreased every year.

[6] Meanwhile, thanks to the current computer technologies and development of the

Internet, a variety of strategy games are sold in the market or offered on-line. For example, Lineage, StarCraft, Warcraft and the like are provided on-line or through Internet cafes to a variety of age groups of computer users and enjoyed by them.

[7] However, except some games (FIFA 2007, Kart Rider, etc.), almost all the battle games are to kill opponents or destruct or capture opponent's buildings. Most games include very strong violence and lascivious contents and are not appropriate for growing children or teens. Also, in the real world, bad effects by on-line games, such as promoting violence, are increasing.

[8] In addition, as is the case with most of violent games, the addictiveness of the games is serious. Some game players are preoccupied only with games, ignoring a social life, which causes huge manpower loss and economic loss to society.

[9]

[10] In order to solve the above problems, on-line baduk games which can be pleasantly played with a variety of persons in an on-line method utilizing the Internet are being offered by making the best use of various educational and creative characteristics that traditional baduk has and the merit of favorable use of spare time.

[11] However, since most of on-line baduk games employ the rules of the baduk without change and simply move the rules to an on-line space, the on-line baduk games have all the above problems that the general baduk has.

[12] In addition, there is an on-line baduk game method in which in order to solve the above problems and to stimulate interest in baduk games in an on-line space a land mine is laid on an intersection and if a stone is placed on the intersection, a predetermined score is deducted. However, this method has a problem in that preparation of a game is burdensome because baduk game players should set locations for laying land mines one by one before a game begins, except the laying of land mines, all the existing baduk rules are included in the method, and therefore the method has all the problems the previous baduk games have.

[13] Also, there are on-line games in which a baduk board is replaced by a map on which lines are drawn as a baduk board. According to the games, a baduk game is played by using the map instead of a baduk board, and then an area on the map to which an obtained territory belongs is acknowledged as the area of the winner, and registered in an on-line space so that the territory can be continuously expanded on the map through continuous games. However, since these games also have all the problems of the general baduk, these games are not played actively.

[14] Thus, there are a variety of programs grafting baduk onto on-line games under development but games that can compete with other violent games in an on-line space have not been developed yet.

[15]

Disclosure of Invention Technical Problem

[16] The present invention provides a board game utilizing baduk rules in which the problems of conventional games grafting baduk onto on-line games can be solved, thereby allowing everyone from children to adults to easily learn rules of the board game by investing a short time and enjoy the board game, and violent and unin- structive problems can be solved, thereby allowing a variety of persons to enjoy the board game on-line or in a personal computer in a speedy process.

[17] More specifically, the present invention provides a map having M x N intersections in which M horizontal lines and N vertical lines intersect, and ordinary stones given basic scores mixed with stones given at least one of additional scores. The instant the stone is placed on an intersection of the map, the score is made to be added or subtracted and displayed. By selecting a map with a small size, the result of a game can be learned quickly. In this way, the present invention doubles amusement together with quick progress of a game, and allows the state of a game in progress to be identified in real-time.

[18] In addition, an object of the present invention is to allow more exciting and more strategic board game to be enjoyed by playing the game after making stones placed on a plurality of intersections on the map as described above at the same time in an initial opening stage.

[19] In addition, when intersections at which stones are placed are overlapping, the stones placed at the overlapping intersections are removed and the intersection from which the stones are removed may be set as an intersection given a score to be added or deducted or as a blank. In this way, the present invention maintains objectivity of strategic placement of stones and doubles the amusement of a game.

[20] In addition, in order to determine a first player who places a stone first, players are made to bet deom (extra compensation), and a player who bets more deom (extra compensation) is determined as the first player. As the first player places a stone, a game begins and the other player adds the deom (extra compensation) obtained in the betting to her/his score. In this way, the present invention allows the condition of deom (extra compensation) occurring in baduk to be objectively set.

[21] In addition, while a game is in progress, a player is allowed to place stones given different additional scores at desired intersections according to a predetermined rule so that a stone with a higher score cannot be a captured stone and the opponent can be induced to have to place a stone given an additional score at an intersection at which the stone is doomed to be a captured stone. In this way, the present invention increases suspense and excitingness of the game.

[22] In addition, while a game is in progress, each player is allowed to place a hidden stone at least more than once that the opponent cannot see but only the player can see, at a location where the player's stones are surrounded by the stones of the opponent in such a way that only with one stone the surrounded stones cannot be saved, or where at least two or more stones are required to reverse the game. In this way, the present invention doubles amusement of the game by giving a variety of opportunities to reverse the game according to the locations of hidden stones of the players.

[23] In addition, in order to display the progress of the game as described above, the scores are made to be displayed on a score board in real-time, the instant a stone is placed on the map or removed from the map, for example, when a stone is placed on the map, or when a stone is removed from the map as a captured stone, or when a stone is placed on an intersection given a score to be added or deducted. In this way, the present invention allows game players to execute an operation quickly according to the scores, and allows those who watch the game in progress, to easily identify the current progress of the game.

[24] In addition, the present invention provides a program so that a board game utilizing baduk game rules as described above can be executed in a computer or an electronic game apparatus, and a player can play the game with a computer as an opponent. In this way, the present invention allows a player to enjoy the board game alone.

[25] In addition, a game server offering the board game is established and computer users having access to the Internet are induced to register as members so that they can enjoy the game with an opponent connected on an on-line space. In this way, the present invention allows a variety of persons to enjoy a variety of types of board games.

Mode for the Invention

[62] The present invention relates to a recording medium having embodied thereon a board game program utilizing baduk rules, and an on-line battle board game system and method utilizing baduk rules. According to the present invention, a game is played by utilizing established patterns or basic opening placements of baduk according to baduk rules, but unlike the conventional baduk, a map with a size of M x N formed by M horizontal lines and N vertical lines and the same stones as baduk stones are used. The winner of the game is not determined by the number of intersections in a territory obtained by a player when the game is finished, but whenever a stone is placed on an intersection, a score is added or deducted and displayed in real-time, and a player who has the highest final score becomes the winner of the game. The present invention will now be explained in more detail with reference to embodiments illustrated in the attached drawings.

[63]

[64] First, FIG. 1 is a diagram illustrating a map and stones used in a battle board game utilizing baduk rules according to an embodiment of the present invention, in which FIG. l(A) illustrates the map 10 used in the current embodiment and FIG. l(B) illustrates the stones used in the current embodiment.

[65] The map 10 has M x N intersections in which M horizontal lines and N vertical lines intersect like a baduk board shape. The map 10 also has addition intersections 12 and deduction intersections 11. A plurality of intersections located on sides that are regarded as not important in baduk rules are selected and displayed as the addition intersections 12. A plurality of intersections are selected from among intersections which are regarded as established patterns and are important in opening placements, and displayed as the deduction intersections 11.

[66] In this case, the map 10 may be formed such that the number of the horizontal lines

(M) of the map can be 5<M<19, and the number of the vertical lines (N) can be 5<N<19. For the deduction intersections 11, a plurality of intersections that are used mainly in opening placements from among established patterns are set and indicated by one color. For the addition intersections 12, a plurality of intersections from among in- tersections on sides that are not important are set and indicated by different colors. In this case, the size of the map may be set up as 5 x 5, 11 x 11, 15 x 15, or 19 x 19, by considering the degrees of players' understanding of rules and the speed of playing a game in particular.

[67] Also, as illustrated in FIG. 2, a map (10A) has M x N intersections in which M horizontal lines and N vertical lines intersect like a baduk board shape, and instead of the addition intersections 12 and the deduction intersections 11, the map (10A) sets an addition area 13 or a deduction area 14 which are obtained by coloring, with a different color, at least two or more adjacent cells from among cells formed by the horizontal lines and the vertical lines. If a stone is placed on an intersection included in the addition area 13, a predetermined score to be added is added to the score of the stone. If a stone is placed on an intersection included in the deduction area 14, a predetermined score to be deducted is deducted from the obtained score of the stone. That is, all the intersections in the addition area 13 are set up as addition intersections and all the intersections in the deduction area 14 are set up as deduction intersections.

[68] Next, a set of stones 20 to be placed on the map 10 are set to have two colors as the colors of baduk stones. The stones are divided into opening stones 21 which are indicated by dots or figures having different colors from the colors of the stones (for example, red dots are marked on the white stones and black stones, respectively) to be used for opening placements, score addition stones 22 which are indicated by dots or figures having different colors from those of opening stones (for example, yellow dots are marked on the white stones and black stones, respectively), and ordinary stones 23 to be used in the process of game after opening placements. Thereby, players can distinguish between the stones 21, 22 and 23. In an embodiment, scores may be set up such that 5 points are given to the opening stone 21, 3 points are given to the score addition stone 22, and 1 point is given to the ordinary stone 23.

[69] Also, in the set of stones as described above, the score addition stones may be set up to have a variety of scores to be added discriminately such as scores of 2, 3, and 4. In this case, the mixing ratio of ordinary stones and score addition stones may be set up as Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂...≥N_n).

[70] The rules for playing a game by using the map 10 or the stones 20 as described above are as follows. (1) For opening placements of stones, a plurality of opening stones 21 are simultaneously placed at desired locations. (2) After placements of opening stones, through deom (extra compensation) betting a game player who bets more deom (extra compensation) is determined to be the first player. In this case, the deom betting may be performed before the opening placements. (3) In playing a game, the ordinary stones 23 and the score addition stones 22 are made to be placed Ni times, N₂ times, ... and N_n times, respectively, from the first placement to the placement of limit number being the sum of the mixing ratio of the ordinary stones and the score addition stones (Ni + N₂+ ... + N_n), when the mixing ratio of ordinary stones and score addition stones is set up as Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂>...> N_n). Then, each ordinary stone 23 and score addition stone 22 can be used repeatedly according to the prior order of placements of the ordinary stones and the score addition stones. For instance, when the ordinary stones Ni having 1 point each, the score addition stones N₂ having 2 points each, and the score addition stones N₃ having 3 points each are mixed at the ratio of 5 : 3 : 2, the sum of the mixing ratio of the ordinary stones and the score addition stones (Ni + N₂+ ... + N_n) is 10, wherein, from the first placement to 10^th placement, the ordinary stones (Ni) can be placed 5 times, the score addition stones (N₂) having 2 points each can be placed 3 times, and the score addition stones (N₃)having 3 points each can be placed twice. Thereafter, each ordinary stone and score addition stone can be used repeatedly at every Next 10^th placement (for example, from the 11^th to the 20^th placement, and from the 21^st to the 30^th placement), according to the order of placements of the ordinary stones and score addition stones from the first placement to the 10^th placement. That is, if a game player placed the ordinary stones 5 times, the score addition stones having 2 points each 3 times, and the score addition stones having 3 points each twice within 10 placements being the sum of the mixing ratio of the ordinary stones and the score addition stones, by making the 1^st placement ordinary stone, the 2^nd placement ordinary stone, the 3^rd placement score addition stone having 2 points, the 4^th placement - score addition stone having 3 points, the 5^th placement - ordinary stone, the 6^th placement - score addition stone having 3 points, the 7^th placement - ordinary stone, the 8^th placement - score addition stone having 2 points, the 9^th placement - ordinary stone, the 10^th placement - score addition stone having 2 points, the same ordinary stone and score addition stone can be placed at every Next 10 ^th placement, for example, from the 11^th to the 20^th placement, and the 21^st to the 30^th placement, according to the order of placements of the ordinary stones and score addition stones from the first to the 10^th placement. (4) Each player is requested to write a predicted intersection of the opponent in advance, and if the opponent places a stone at the inducement intersection, a bonus score is given. (5) While a game is in progress, a hidden stone (which a game player to use the hidden stone can see but the opponent cannot see) is provided so that the hidden stone can be used when the game player thinks it is an important turning point. (6) For calculation of scores during and after a game the scores of stones and the scores of intersections are added in real-time when a stone is placed on the map, and the winner is determined by calculating [the total score of placed stones + deom + bonus score + the scores of addition intersections - the scores of deduction intersections]. In this case, any one or more of the rules (1) through (6) described above can be used while a game is in progress.

[71] A game is played according to ordinary baduk rules by which game players place the stones in turn one after another, except the rules described above. Even without knowing baduk rules and established patterns, everyone that knows the concept of a captured stone can play the game according to the rules described above.

[72]

[73] Next, FIG. 3 illustrates a process for executing a battle board game by driving in a computer a recording medium recorded with the battle board game utilizing baduk rules according to an embodiment of the present invention. The map and stones as illustrated in FIG. 1 are made to be displayed on a monitor of the computer and a program is executed so that the board game is played as the following method.

[74] The method includes: (A) a program driving process for driving a recording medium having embodied thereon a board game utilizing baduk rules by placing the recording medium in the computer; (B) a map selection process for displaying a plurality of maps which each are formed with M horizontal lines and N vertical lines, and which each have a different number or different locations of addition intersections or deduction intersections, the addition intersection being an intersection in which a predetermined score is added when a stone is placed at the intersection at which the horizontal line and the vertical line intersect, and the deduction intersection being an intersection in which a predetermined score is deducted when a stone is placed at the intersection, and requesting a map to be selected from among the plurality of maps; (C) a stone selection process for displaying multiple sets of stones to be placed on the map with each set having a different color, in which a plurality of opening stones, ordinary stones given a basic score, and score addition stones given a score to be added are mixed in different ratios, and requesting a set of stones to be selected from the multiple sets of stones; (D) a game playing process for playing a game by utilizing baduk rules with the selected stones on the selected map and while the game is in progress, determining the winner by displaying scores in real-time by adding the score of a stone and the score of the intersection at which the stone is placed the instant the stone is placed on the map.

[75] In this case, the maps provided in the map selection process (B) may be provided only with different numbers of intersections without providing the addition intersections or the deduction intersections. The stones provided in the stone selection process (C) may be only ordinary stones having different colors and given a basic score.

[76]

[77] Also, (E) a simultaneous opening placement process for allowing game players to place opening stones on at least two or more intersections at the same time may be further included before the game playing process (D).

[78] Also, before the game playing process (D) or after the opening placement process

(E), (F) a deom (extra compensation) betting process for requesting players to input the number of deom in order to determine a player who inputs a larger deom as the first player may be further included.

[79] The battle board game method utilizing baduk rules of the present invention which is formed by the processes (A) through (D) explained with reference to FIG. 3, or further including the processes (E) and (F) performed in the process (D) is provided in the form of a program recorded on one recording medium such that the program can be installed in a hard disk of a personal computer or can be driven from a CD-ROM, a DVD-ROM or a variety of reproduction apparatuses. This is to allow owners of personal computer to buy a recording medium recorded with the battle board program and to play the game alone with the computer as the opponent.

[80] Each process will now be explained in more detail. In the map selection process (B), as illustrated in FIGS. 1 and 2, a plurality of maps which each are formed with M horizontal lines and N vertical lines, and which each have a different number or different locations of addition intersections or deduction intersections, the addition intersection being an intersection in which a predetermined score is added when a stone is placed at the intersection at which the horizontal line and the vertical line intersect, and the deduction intersection being an intersection in which a predetermined score is deduced when a stone is placed at the intersection are provided, or a plurality of maps which each have M x N intersections in which M horizontal lines and N vertical lines intersect, are provided in which an addition area or a deduction area which is obtained by coloring, with a different color, at least two or more adjacent cells from among cells formed when the horizontal lines and the vertical lines intersect is set up, and a score to be added or to be deducted is set up to the intersections included in the areas indicated by the different colors. In this way, a computer user (hereinafter referred to as a "game player") can select a map from among the plurality of maps. In this case, the size of the map is formed such that the number of the horizontal lines (M) of the map can be 5<M<19, and the number of the vertical lines (N) can be 5<N<19. When the speed of game progress and the level of the game are considered, the size of the map may be one of 11 x 11, 15 x 15 and 19 x 19. Also, maps having different addition intersections and deduction intersections or different numbers or sizes of additional areas or deduction areas are provided so that the game players can select a map. [81] Next, as one set of stones provided in the stone selection process (C), a plurality of opening stones, ordinary stones, and score addition stones are provided with mixing in a predetermined ratio. That is, the one set of stones include ordinary stones and at least one or more types of score addition stones which each have a score greater than that of the ordinary stone. The ordinary stones and score addition stones are provided with being mixed in a ratio of Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂>... > N_n). Accordingly, multiple sets of stones having different numbers and scores of opening stones, different types and numbers of score addition stones, and different mixing ratios of ordinary stones and score addition stones are provided to the game players so that each game player can select one set of stones.

[82] As an embodiment, if one type of score addition stones and ordinary stones are mixed in a mixing ratio of 1:4 as illustrated in FIG. 4, and the time to use a score addition stone 22 is determined within the first five placements, and the score addition stone 22 is used first time in the third placement, then, after the first placement of the score addition stone 22, the game is played with the score addition stone 22 being used once in every fifth placement relative to the third placement, that is, in the eighth placement, in the thirteenth placement, in the eighteenth placement, and so on.

[83]

[84] A method of implementing the map and stones selected in the processes (B) and (C) described above in a computer will now be explained. According to the method, as illustrated in FIG. 5, the selected map 81 is disposed at the center of a computer monitor 80 of a game player, the stones 82 of the opponent (computer) are disposed on the left- hand side, and the stones 83 of the game player are disposed on the right-hand side. On top of the screen, a score board 84 is displayed in preparation for playing a game. Also, if the game player's or the opponent's turn to use a stone comes up, ordinary stones 85 and score addition stones 86 are displayed so as to be distinguished from each other, thereby allowing a stone to be selected and used.

[85] Next, in the game playing process (D), a game is played by players alternately placing a stone on a map as baduk. In this case, except opening stones, the one set of stones include one or more types of score addition stones which each have a score greater than that of one ordinary stone. Since the ordinary stones and the score addition stones are mixed in a ratio of Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂>... > N_n) and provided, a step in which the ordinary stones and the score addition stones are made to be placed N i times, N₂ times, ..., and N_n times, respectively, within a limit number of placements, the limit number being the sum of the mixing ratio of the ordinary stones and the score addition stones (Ni + N₂+ ... + N_n), and a step in which, from the Next placement after the ordinary stones and the score addition stones are made to be placed Ni times, N₂ times, ..., and N_n times, each ordinary stone 23 and score addition stone 22 is made to be used again according to the prior order of placements of the ordinary stones and the score addition stones, are included and the game is played until there is no more intersection on the map at which a stone can be placed.

[86] In this case, as another embodiment of using method of the ordinary stones and score addition stones, when ordinary stones (Ni) given a score of 1 and score addition stones (N₃) given a score of 3 are mixed in a ratio of 4: 1, a score addition stone is used once and ordinary stones are used 4 times within the first five placements. At this time, a score addition stone is used at the 3^rd placement, and then, the game is played with the score addition stone being used once again in every Next fifth placement. For instance, the score addition stone is used again at the 8^th and 13^th placement, respectively, during the placements from 6^th to 10^th, and 11^th to 15^th.

[87] While the game is played through the game playing process (D) as described above, the score of an ordinary stone or score addition stone is added and displayed on the score board 84 in real-time the instant the stone is placed on an ordinary intersection of the map. Also, while the game is in progress, if a stone is placed at an addition intersection or a deduction intersection, the score of the addition intersection is added or the score of the deduction intersection is deducted and the resulting score is displayed on the score board 84. When stones of the opponent are removed as captured stones by an array of stones of one game player, the score obtained by the removed stones is subtracted from the score of the opponent to be displayed on the score board 84.

[88] As described above, the score is displayed in real-time while the game is played, and a player having a higher final score becomes the winner. While the game is played, if there is no more intersection at which a stone can be placed, the game is finished. Here, a process for determining a winner may be further included in which while each game player fills stones in intersections of a secured territory, the score is added and displayed in real-time and a player having a higher final score is determined as the winner.

[89] The process for determining a winner includes: a step for finishing a game when there is no more intersection at which a stone can be placed by any game player, letting each game player fill ordinary stones in the intersections of a secured territory and adding in the score board the scores of ordinary stones which fill the intersections of the secured territory; and a step for determining the added scores on the score board and determining a game player or a computer obtaining a higher score as the winner.

[90]

[91] Also, while a game is in progress, in order to increase the suspense and reversals of the game, and strategy amusement, the board game program utilizing baduk rules recorded on a recording medium of the present invention may further include: (D-I) an inducement intersection execution process for setting an inducement intersection at which the opponent is expected to place a stone and, if the opponent places a stone at the inducement intersection, earning a bonus score; and (D-2) a hidden stone using process for using a hidden stone at least once.

[92] The inducement intersection execution process (D-I) includes: an inducement intersection setting step for requesting a game player to input an inducement intersection for inducing the opponent to place a stone by predicting a location at which the opponent is to place a selected stone on a selected map, and setting a score of the inducement intersection; and a score addition step for notifying the opponent of the inducement intersection if the opponent places a stone at the inducement intersection, awarding the game player setting the inducement intersection a predetermined bonus score, and adding the bonus score to the score of the game player. Also, a step for automatically terminating an inducement intersection if 10 or 20 placements are performed without the opponent placing a stone at the inducement intersection after the inducement intersection is set, may be further included so that strategies and tactics for inducing the opponent to place a stone in a short period at the inducement intersection can be set up.

[93]

[94] Also, the hidden stone using process (D-2) includes: a hidden stone placing step for requesting use of a hidden stone that can be placed so that the opponent game player cannot watch the hidden stone in the middle of a game, and placing the hidden stone at a desired intersection; and a hidden stone displaying step for, if the opponent game player places a stone at the intersection of the hidden stone, or if stones of the opponent are removed as captured stones surrounded by a stone of the other gamed player linked to the hidden stone, displaying the hidden stone to the opponent game player, so that the opponent game player can see the hidden stone.

[95] FIG. 6 illustrates an embodiment of a process for using the hidden stone.

[96] As illustrated in FIG. 6(A), black stones are surrounded by white stones and the black stones have a territory of 4 empty intersections. Accordingly, the player of white stones cannot make the black stones as captured stones to be removed. However, if the game player of black stones does not place a stone in the territory twice or more times, the game player of white stones can capture the black stones. If a situation like this happens, the game player of white stones requests use of a hidden stone and places the hidden stone (A) at an intersection 2. In this case, the hidden stone is displayed only on the terminal of the player who uses this, and the game player of black stones cannot see the hidden stone. Accordingly, if the game player of black stones does not know that the hidden stone is placed there and places a stone in any other area, then, the game player of white stones places a white stone at an intersection 1 in her/his Next turn as illustrated in FIG. 6(B). If the two white stones are placed in the territory of the black stones, the black stones are to be captured in the following placements. However, if the game player of black stones predicts the location of the hidden stone and places a black stone at the intersection 1 or 2, the use of the hidden stone by the game player of white stones comes to nothing.

[97]

[98] Next, the opening placement process (E) includes: an opening placement step in which both the game player and the computer place opening stones simultaneously at least on two or more desired intersections and the game player cannot see the opening stones of the opponent (computer); an opening placement display step in which after the last opening stone is placed, the opening stones of both the game player and the computer are displayed on the map; an opening stone location confirmation step in which the opening stone locations of the game player and the computer are examined in order to confirm whether or not there is an intersection at which opening stones of both the game player and the computer overlap; and an opening placement finishing step in which if there is no intersection at which opening stones of both the game player and the computer overlap, placement of opening stones is finished. Also, a step in which if there is an intersection at which opening stones of both the game player and the computer overlap, the opening stones of both the game player and the opponent (computer) are not displayed and the intersection is designated as an addition intersection which is marked by a dot or a figure having a color different from that of ordinary intersection and adds the score of addition to the overlapped intersection, a deduction intersection which is marked by a dot or a figure having a color different from the addition intersection and deducts the score of deduction from the overlapped intersection, or a prohibited intersection on which no player can place a stone, and then, placement of opening stones is finished, may be further included.

[99] As an embodiment, as illustrated in FIG. 7(A), if the game player of white stones places opening stones at (3,4), (4,3), and (11,11), and the game player of black stones places opening places at (4,10), (5,12), and (11,4), there is no intersection at which opening stones of both the game players overlap, and the opening stones are displayed on terminals so that the players can see those of the opponents. However, if the game player of white stones places opening stones at (4,6), (5,4), and (11,4) and the game player of black stones places opening places at (10,12), (11,4), and (12,11) at the same time, the locations of the opening stones at (11,4) overlap as illustrated in FIG. 7(B). In this case, all the overlapping opening stones 21 at the intersection A are removed, and then the intersection A may be set as an addition intersection or a deduction intersection or a prohibited intersection, and the game is played. In this case, the instant the opening stones 21 are placed on the map, the scores of the opening stones 21 (for example, if an opening stone of a score of 5 is used, the score of the opening stones illustrated in FIG. 7(A) is 15, and the score of the opening stones illustrated in FIG. 7(B) is 10) are added and displayed on the score board. Also, the number of the opening stones may be selectively used according to the size of the map.

[100] Next, the deom betting process (G) includes: a step for inputting the number of deom to be given to the opponent in order to be a first player when the game begins or after the opening placement is finished; a step in which, if the deom of a game player is input, the deoms bet by the computer and the game player are displayed; and a step for determining one player who bet more deom as the first player and adding the deom points bet by the first player to the score board of the second player.

[101] Also, a step in which if the deoms bet by the players are the same, both game players are requested again to input deoms to bet to repeat the deom betting; and a step in which if the bet deoms are the same again, stone selection is performed in order to select a first player, and the score of the bet deom is added to the score board of the second player may be further included.

[102]

[103] The battle board game method utilizing baduk rules, including the processes (A) through (E), or further including any one or both of the processes (F) and (G) in addition to the processes (A) through (E) as described above, is prepared as a program that can be executed in a computer, and the program is recorded on a recording medium and provided to personal computer owners.

[104]

[105] Next, FIG. 8 is a schematic block diagram illustrating a structure of an on-line battle board game system utilizing baduk rules according to an embodiment of the present invention. The system includes member terminals 200; and a board game server 100.

[106]

[107] The board game server 100 provides to the member terminals 200, a plurality of maps which each are formed with M horizontal lines and N vertical lines, and which each have ordinary intersection, and a different number or different locations of addition intersections or deduction intersections, the ordinary intersection being an intersection in which only the score of a stone is given when the stone is placed at the intersection at which the horizontal line and the vertical line intersect, the addition intersection being an intersection in which a predetermined score is added when a stone is placed at the intersection, and the deduction intersection being an intersection in which a predetermined score is deducted when a stone is placed at the intersection; multiple sets of stones to be placed on the map, in which a plurality of opening stones, ordinary stones given a basic score, and score addition stones given a score to be added are mixed in different ratios. By providing the maps and the stones, the board game server 100 allows a map and a set of stones to be selected. Further, the board game server 100 makes a member select an opponent member desired to play with, and provides selected map and stones to the member terminal and the opponent member terminal so that a game can be played according to baduk rules. While a game is in progress, when a stone is placed at an intersection on the map, the board game server 100 adds in real-time the score of the stone and a score given to the intersection to be added or deducted, and displays the result on a score board, and determines a member having a higher final score as the winner of the game.

[108]

[109] Next, FIG. 9 is a diagram illustrating a schematic structure of the board game server illustrated in FIG. 8. The board game server 100 includes a member registration/authentication unit 110, a member information DB 120, a map/stone selection unit 130, a member selection unit 140, a game playing means 150, and game result processing unit 160. The member registration/authentication unit 110 receiving a member registration request from internet users, receives and verifies input of personal information, and then registers a member and provides an ID and/or password, and if a registered member inputs an ID and/or password and requests access, authenticates the request and permits the access. The member information DB 120 stores and manages personal information of the registered members and all information related to games. The map/ stone selection unit 130 makes a member who has accessed the server 100 after registration/authentication, select a map and stones if the member wants to play a game. The member selection unit 140 makes the member who selected the map and stones select an opponent member to play with. The game playing means 150 makes the selected opponent member connected, and a game played such that when a stone is placed at an intersection on the map, the score of the stone is added in real-time to a score given to the intersection to be added or deducted. The game result processing unit 160 determines the winner of the game if the game is finished and stores the game result in a member DB.

[HO]

[111] Also, in the member information DB 120, general information on members, the number of played games for each map, the numbers of wins and losses, game records, game levels and the like are stored and according to a request from a member who wants to play a game with another member, the information of the other member can be viewed.

[112]

[113] Also, in order to allow a member who wants to play a game to select a map by considering her/his game level or time to play a game, the map/stone selection unit 130 provides a plurality of maps which each are formed with M horizontal lines and N vertical lines, and which each have ordinary intersections, and a different number or different locations of addition intersections or deduction intersections, the ordinary intersection being an intersection in which only the score of a stone is given when the stone is placed at the intersection at which the horizontal line and the vertical line intersect, the addition intersection being an intersection in which a predetermined score is added when a stone is placed at the intersection, and the deduction intersection being an intersection in which a predetermined score is deductedd when a stone is placed at the intersection, or provides a plurality maps which each have M x N intersections in which M horizontal lines and N vertical lines intersect and in which an addition area or a deduction area which is obtained by coloring, with a different color, at least two or more adjacent cells from among cells formed when the horizontal lines and the vertical lines intersect is set and a score to be added or to be deducted is given to the intersections included in the areas indicated by the different colors. In this case, the map is formed such that the number of the horizontal lines (M) of the map can be 5<M<19, and the number of the vertical lines (N) can be 5<N<19. When the time and level of a game are considered, any one of H x 11, 15 x 15 and 19 x 19 may be selected. In this case, the addition or deduction intersection or the addition or deduction area are not fixed, and a variety of types of the intersections or areas are provided so that members can select one.

[114] Also, as stones provided together with the maps, multiple sets of stones in which opening stones, score addition stones and ordinary stones are mixed in a predetermined ratio and have different colors are provided so that a set of stones having desired colors can be selected.

[115] Accordingly, as illustrated in FIG. 10, the map/stone selection unit 130 includes an intersection setting unit 131, a map providing unit 132, a stone setting unit 133, and a stone providing unit 134. The intersection setting unit 131 sets an addition intersection and a deduction intersection according to maps of a variety of sizes having M horizontal lines and N vertical lines. The map providing unit 132 transmits to a member terminal the maps of a variety of sizes having the addition intersections and deduction intersections set in the intersection setting unit 131 so that a map can be selected. The stone setting unit 133 sets the numbers and scores of opening stones, and the numbers and scores of ordinary stones and score addition stones so that the ordinary stones and one or more types of score addition stones which each have a score at least greater than that of the ordinary stone can be included to be mixed in a predetermined ratio of Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂>...≥N_n). The stone providing unit 134 sets a different color to each selected set of the stones and transmits to a member terminal so that the member can select stones.

[116] In this case, an intersection input unit 135 for allowing a member to input the numbers and locations of addition intersections and deduction intersections so that the member can select addition intersections and deduction intersections in the selected map, and a stone ratio input unit 136 for allowing a member to input the numbers and scores of opening stones, ordinary stones and score addition stones so that the stones can include ordinary stones and one or more types of score addition stones which each have a score at least greater than that of the ordinary stone to be mixed in a ratio of Ni : N₂ : ... : N_n (here, Ni corresponds to the number of the ordinary stones 23 given a basic score 1 point each, N₂ corresponds to the number of the score addition stones given 2 points each, and N_n corresponds to the number of the score addition stones given n points each, and Ni≥N₂>...≥N_n), may be further included in order to allow the member to set a map and stones by her/himself.

[117] Also, in the intersection input unit 135, the range and location of an area, and the score of an intersection included in the area can be input and set up in order to set up an addition area or a deduction area.

[118]

[119] Next, the member selection unit 140 makes the member, who has accessed the board game server and selected the map and stones from the map/stone selection unit 130, select or invite an opponent member to play with.

[120] As illustrated in FIG. 11, the member selection unit 140 includes an invitation room opening unit 141 for displaying information on a map and stones selected by a member and inviting an opponent member who wants to play a game on the map; and a game connection unit 142 for, if a desired member is selected from among members entering into the invitation room, transmitting the map to the terminal of the selected member and making the selected member select the color of a set of stones to be used in a game. Also, an invitation room search unit 143 in which a member who does not select a map can select a member who opens an invitation room with a desired map; and an invitation room selection unit 144 for selecting an invitation room searched by the invitation room search unit and entering the room may be further included such that a game opponent member can be directly selected without going through the map/stone selection unit. [121]

[122] Next, the game playing means 150 is to play a game by placing opening stones by using a map and stones displayed on member terminals of the members, or by determining a first player according to deom betting, after finishing selection of an opponent and preparation works to play a game through the member selection unit 140, and while a game is in progress, the instant a stone is placed at an intersection on the map, the game playing means 150 adds in real-time the score of the stone and the score of the intersection to display the resulting score. Basically, the game playing means 150 includes a game playing unit 153 for playing a game by making players from a first player place stones on the map according to a placing order corresponding to a mixing ratio of ordinary stones and score addition stones, and a score display unit 155 which if a stone is placed at an intersection on the map through the game playing unit 153, adds the score of the stone and the score of the intersection and displays the result on the member terminals of the game players in real-time. In this case, the game playing unit 153 allows a game to be played such that the ordinary stones and the score addition stones are made to be placed Ni times, N₂ times , and N_n times, respectively, within a limit number of placements, the limit number being the sum of the mixing ratio of the ordinary stones and the score addition stones (Ni + N₂+ ... + N_n), and from the Next placement after the ordinary stones and the score addition stones are made to be placed Ni times, N₂ times, ..., and N_n times, each ordinary stone 23 and score addition stone 22 is made to be used again according to the prior order of placements of the ordinary stones and the score addition stones.

[123] Also, as illustrated in FIG. 12, an opening placement unit 151 and a deom betting unit 152 may be selectively or all included. In the opening placement unit 151, game players place a plurality of opening stones at desired intersections such that they cannot be seen by the other players and it is determined whether or not there is an intersection at which the opening stones overlap. Then, if there is no such intersection, the opening stones are displayed so that both players can see the opening stones, and if there is an intersection at which opening stones overlap, the intersection is informed to the players and the opening stones at the intersection is removed and not displayed, and then, the intersection is set up as an addition intersection which is marked by a dot or a figure having a color different from that of ordinary intersection and adds the score of addition to the overlapped intersection, or a deduction intersection which is marked by a dot or a figure having a color different from the addition intersection and deducts the score of deduction from the overlapped intersection. In the deom betting unit 152, if the opening placements are finished in the opening placement unit 151, in order to determine a first player between the game players, the game players are made to bet deom to be given to the opponent game player. The game player betting more deom is determined as the first player, and the score of the deom bet by the first game player is given to the game player who becomes the second player.

In this way, a game may also be played by making members directly input through a terminal the types of stones, the score for each type, and a mixing ratio.

[140] The member invitation and selection process (iv) is to select a desired game opponent player after selecting the map and stones, and can include: (iv-1) a process in which a first member who wants to play a game indicates information on the selected map and stones, opens an invitation room for inviting other members, and a second member enters the invitation room and is selected as a game opponent after an intention of the second member to play a game is checked; or (iv-2) a process in which a first member who wants to play a game enters an invitation room of a second member indicating map information appropriate to the first member, and the first player is selected as a game opponent after an intention to play a game is checked.

[141] The process (iv-1) includes: a step for a member indicating information on the selected map and stones and opening an invitation room for inviting other members who want to play a game; a step for checking an intention to play a game through individual chat with the other members who have entered the opened invitation room; and a step for selecting one member among the contacted members. The process (iv-2) includes: a step for a first member who wants to play a game searching invitation rooms of other members without selecting a map and stones and selecting an invitation room having a map and stones desired by the first member; a step for entering the selected invitation room and checking an intention to play a game of the member who opened the room; and a step for waiting for the member who opened the room to select an opponent through the member's terminal among the other members who checked an intention to play a game. If the first member is not selected as an opponent, the process (iv-2) is repeated so that a game opponent can be selected.

[142] Next, if a game opponent is selected through the member invitation and selection process (iv), the map and stones selected by one member are made to be displayed on terminals of the two members so that a game can be prepared.

[143] Next, in the game playing process (v), a map and stones selected for a game by the first member are displayed on the member terminals of the first member and the opponent members selected by the first member and a game is played by utilizing baduk rules, and if a stone is placed at an intersection on the map, the score of the stone and the score given to the intersection to be added or deducted are added and displayed on a score board in real-time. The game playing process (v) includes: a step in which the ordinary stones and the score addition stones are made to be placed Ni times, N₂ times , and N_n times, respectively, within a limit number of placements, the limit number being the sum of the mixing ratio of the ordinary stones and the score addition stones (Ni + N₂+ ... + N_n), and; a step in which after the ordinary stones and the score addition stones are made to be placed Ni times, N₂ times, ..., and N_n times until the same number of stones as the sum of the mixing ratio of the ordinary stones and score addition stones (Ni + N₂+ ... + N_n), each ordinary stone 23 and score addition stone 22 is made to be used again according to the prior order of placements of the ordinary stones and the score addition stones whenever the same number of stones as the sum of the mixing ratio are placed.
