Description

  The present invention relates to a program, a game system, and a game control method. More specifically, the present invention relates to game control, etc., in which a lottery is randomly performed in a battle game and the lottery result is reflected in the game content.

  A game that can be played by a plurality of users using a so-called arcade game machine provided in an amusement facility or the like has been proposed. In recent years, there has also been proposed an online game played by a plurality of users connected to a server via the Internet by connecting an arcade game machine to the Internet.

  In addition, as an online game like this, players can compete nationwide for superiority or inferiority in game skills (skills) regardless of region, and announce rankings regarding the number of wins, defeats, consecutive wins, total points, etc. Some offer services. As an example, in the case of an online mahjong game, rankings are announced, and experience values are given to players according to the battle results, and if experience values are accumulated more than a certain value, the rank indicating the player's skill rank is Additional services such as promotion are also provided.

  By the way, in games such as mahjong games that are distributed at the time of play and self-recognize a certain game from the foot of a mountain, card games that hand cards are distributed, etc. The computer draws randomly (randomly) and automatically distributes items based on the lottery results to advance the game. However, when a lottery is performed by a computer in a game having such a random element, the player is dissatisfied with the fairness of the lottery result than when the lottery is performed with a physical element (for example, dice or roulette). The fact is that it is easy. In fact, in the case of a mahjong game, for example, important factors such as platter and tsumo are left to the computer lottery, so that certain players will be advantageous or disadvantaged, especially among those who are not satisfied with the competition results. In addition, the system is performing artificial operations (for example, deceptive acts such as selecting a random number seed or adding a random seed so that a specific player can gain an advantage). There are those who have dissatisfaction and suspicion.

  In order to dispel such dissatisfaction and doubts, for example, for a card game, the cards displayed by the computer are sufficiently stirred, and the order of the cards obtained by stirring is recorded. There has been proposed a game apparatus in which a card is used for selection by a player in a state where the record is hidden in advance, and the recorded arrangement order is disclosed after the game is over (see Patent Document 1).

  In addition, for mahjong games, for example, on the official website of the manufacturer of the game (for example, the official website of the applicant of the present application), there is no artificial manipulation (frauding) regarding Yamanari Narumi and Tsumo-an. Some have tried to resolve player dissatisfaction and suspicion by announcing that they have not (see Non-Patent Document 1).

  In addition, some online mahjong games (so-called net mahjong) have a function of disclosing random seeds after the game is over (see, for example, Non-Patent Document 2).

Japanese Examined Patent Publication No. 6-30688

Special Feature-SEGA Network vs Mahjong MJ4 Evolution Official Site, SEGA, [Search January 24, 2011], Internet <URL: http://www.sega-mj.com/mj4evo/sp_faq.html> Online Mahjong Tengu, Sea Egg Co., Ltd. [Search January 24, 2011], Internet <URL: http://tenhou.net/>

  However, even if the above measures are taken, there are still some people who are dissatisfied and suspicious, which may be an incentive to leave the user.

  Therefore, the present invention is a program that allows a computer to randomly (randomly) draw lots and distribute the items based on the lottery results to the players so as to eliminate dissatisfaction and doubt about the fairness that the players may have. An object is to provide a game system and a game control method.

  In order to solve this problem, the present inventor has made various studies. For example, there are amusement machines such as online casinos and pachislots that are similar to online competitive games, and some of these products have been proved by a third party to be free from fraud. It is not realistic to adopt such a method for general software. On the other hand, there is a lack of objectivity when game makers and service providers simply make unilateral declarations on websites and manuals. Also, the method of disclosing the seeds of random numbers after the end of the game raises the suspicion that the seeds of random numbers are selected so that a specific player will be advantageous, or that the seeds of random numbers are added afterwards. It has not been wiped away. Considering this, since game makers and service providers cannot actually deceive themselves in the first place, this is communicated to the player in an easy-to-understand manner without compromising the original interest of the game. It is considered important to have the game enjoyed. The inventor who has further studied from such a viewpoint has come to obtain knowledge that leads to the solution of the problem.

The present invention is based on such knowledge, in a computer that randomly draws in a competitive game and reflects the lottery result in the game content,
Generating a unique partial random number seed for each player participating in the game;
Exposing the player-specific partial random seed to the player before the game starts;
Combining the partial random seeds of all players participating in the game to determine a random seed to be used in the game;
Using the random number seed, performing a lottery by a predetermined algorithm disclosed in advance, and reflecting the lottery result in the game;
Exposing the random number seed to the player after the game ends;
It is a program that executes.

  In the present invention, a random number seed (random seed, player seed) used when performing the lottery is disclosed to the player before the game starts, and is also disclosed to the player after the game ends. If desired, the player of such a game checks the random number seed released before the start of the game with the random number seed released after the end of the game and confirms that they match, thereby determining that the random number seed matches the game. It is possible to confirm that the game has progressed fairly without any deceptive actions that will be added later.

  Also, when the random number seeds are disclosed, there is no point in publishing unless the random number seeds are merely a list of characters and numbers unrelated to the lottery act of the game. In this regard, in the present invention, a random number seed is used, and the algorithm when the lottery is performed by a predetermined algorithm is disclosed in advance so that a desired player or the like can be confirmed at any time. The desired player can use the disclosed algorithm to confirm that the lottery result is reflected in the game according to the algorithm.

  In the program according to the present invention, an indeterminate common random number seed that fluctuates according to the game progress content of each player is generated separately from the partial random seed, and the common random seed is further combined with the random random seed combined with the partial random seed. It is preferable to combine and use for the game. By incorporating an indeterminate element that fluctuates according to the progress of the game into the random number seed, the random seed used in the game can no longer be involved or controlled such that the game maker or service provider intentionally operates it. . Therefore, in a game using such a random number seed, there is no room for work by a game maker or the like.

  This program can reflect the lottery result on items distributed to each player in the game. In this case, it is possible to sequentially change the common random number type according to the type of item selected by each player.

  Further, the above-described program may be a program that discloses only a partial random number type unique to each player to each player. If all the random number seeds are released, the game content (for example, application software that reproduces the game contents (such as Ulsan or dice) when the public random number seeds are input) is being played. If there is a concern that all of Ulsan will be known, such a concern will be dispelled if only the partial random number seed unique to the player is disclosed.

  Furthermore, it is also preferable to disclose a partial random number type unique to each player to each player before the matching process (a process for searching and determining an opponent) is completed. If the partial random number seed is disclosed after the matching is completed, it is possible to reflect the result of the matching and generate the random number seed later so that a specific player is advantageous. Considering this point, it is proved that the seed of the random number is not a retrofit by disclosing the partial random seed before matching.

In addition, the present invention is a game control method for randomly selecting a lottery in a battle game and reflecting the lottery result in the game content.
Generating a unique partial random number seed for each player participating in the game;
Publishing a player-specific partial random seed to the player before the game begins;
Combining the partial random seeds of all players participating in the game to determine the random seed to be used in the game;
Using the random number seed, performing a lottery by a predetermined algorithm disclosed in advance, and reflecting the lottery result in the game;
Releasing the random number seed to the player after the game ends;
Is included.

Furthermore, the present invention is a game system in which a lottery is randomly performed in a battle game and the lottery result is reflected in the game content,
Generate a partial random number seed unique to each player participating in the game, release the player-specific partial random seed to the player before the start of the game, and combine the partial random seed seeds of all players participating in the game Then, a random number type to be used in the game is determined, a lottery is performed using a predetermined algorithm disclosed in advance using the random number type, the lottery result is reflected in the game, and the random number type is further reflected in the game. Control means to be disclosed to the player after the end of
An input means for inputting a desired signal when each player progresses the game;
Is provided.

  This game system stores a random number seed after the game is finished, and records or transmits data relating to the stored random number seed to a terminal connected to the system, or the data from the terminal. It may further include a server that allows references to

  According to the present invention, in a game in which a computer randomly draws (randomly) and distributes items based on the lottery result to the player, dissatisfaction and doubt about fairness that the player may have can be solved.

  Each game device 12 is connected to a LAN 20 in the amusement facility 10 and can communicate with other game devices 12 in the amusement facility 10. The LAN 20 of the amusement facility 10 is connected to the Internet 22 and can communicate with game devices 12 in other amusement facilities 10. Therefore, even if the installation location is far away, a common mahjong game can be played by any four game devices (when four players are not available, it is possible to play with a computer (CPU 40)). Has been.

  In such a game apparatus 12, the player sits on a chair (not shown) installed with the game apparatus 12, inserts coins, and operates the touch panel 24, the selection button 26, the execution button 28, and the like. Can play mahjong games.

  The play data management server 30 is connected to the Internet 22. The play data management server 30 collects play data (data related to play) such as a mahjong game executed by the game apparatus 12 via the Internet 22 and accumulates and manages the play data. The play data management server 30 of the present embodiment stores the data of the ranks and experience values of each player. The experience value is given according to the battle result. Each player is given a rank to be promoted when the experience value is accumulated more than a certain value.

(Configuration of game device 12)
A configuration of the game apparatus 12 in the present embodiment will be described with reference to FIGS. FIG. 3 is a block diagram of the game apparatus 12 in the present embodiment.

  The casing 32 of the game apparatus 12 has a display monitor 34 for displaying game contents, a touch panel 24 provided on the display monitor 34 for a player to perform game operations, and a coin insertion unit 36 for inserting coins. An IC card I / F 18 for reading the member's card 16, a selection button 26 for the player to select a bag, and an execution button 28 for executing various operations (see FIG. 1). ). The display monitor 34 displays a realistic state of the game (game field) that can be seen by the player sitting on the seat of the actual mahjong table.

  The game apparatus 12 is used as a CPU 40 that executes game programs, controls the entire system, calculates coordinates for image display, and the like, and a buffer memory that stores programs and data necessary for the CPU 40 to perform processing. A system memory (RAM) 42 is commonly connected by a bus line and is connected to a bus arbiter 44 (see FIG. 3). The bus arbiter 44 controls the flow of programs and data with each block of the game apparatus 12 and devices connected to the outside.

  A game data storage device or storage medium (including an optical disk or optical disk drive for driving a game recording medium such as a CD-ROM) 46 storing a game program and data (including video data and music data), and a game A BOOTROM 48 in which a program and data for starting the apparatus are stored is connected to the bus arbiter 44 via a bus line.

  Also, rendering that reproduces video (MOVIE) data read from the program data storage device or storage medium 46 via the bus arbiter 44, or generates an image for image display according to the player's operation or game progress. A processor 50 is connected to a graphic memory 52 that stores graphic data and the like necessary for the rendering processor 50 to generate an image. The image signal output from the rendering processor 50 is converted from a digital signal to an analog signal by a video DAC (not shown) and displayed on the display monitor 54.

  Also, a sound processor 56 that reproduces music data read from the program data storage device or storage medium 46 via the bus arbiter 44 and generates sound effects and sounds in response to player operations and game progress, and its sound A sound memory 58 for storing sound data and the like necessary for generating sound effects and sounds by the processor 56 is connected. The audio signal output from the sound processor 56 is converted from a digital signal to an analog signal by an audio DAC (not shown) and output from the speaker 60.

  A communication interface 62 is connected to the bus arbiter 44. The communication interface 62 is connected to an external network such as a telephone line via a modem 64. The game apparatus 12 is connected to the Internet via a telephone line by a modem 64, and can communicate with other game apparatuses 12, the network server 30, and the like. The communication interface 62 and the modem 64 use a telephone line. However, the terminal adapter (TA) or router that uses the telephone line, a cable modem that uses a cable TV line, a cellular phone, or a PHS is used for wireless communication. Other communication methods such as communication means and optical fiber communication means using an optical fiber may be used.

  The selection button 26 and the execution button 28 are connected to the bus arbiter 44 via a peripheral I / F (interface) 66. The selection button 26 is used by the player to select a hand. The execution button 28 is used to input instructions for executing various operations. The peripheral I / F 66 outputs a signal for controlling the game apparatus 12 or an externally connected device in accordance with an operation by the player.

  The touch panel 24 is connected to the bus arbiter 44 via a peripheral I / F 68. The touch panel 24 is used for inputting various operations when the player touches his / her finger. The peripheral I / F 68 outputs a signal for controlling the game apparatus 12 or an externally connected device in accordance with an operation by the player. The touch panel 24 functions as a position coordinate acquisition unit that acquires the coordinate value of the position touched by the finger and generates position coordinate information.

  The bus arbiter 44 is connected to an IC card I / F 18 for reading the members card 16.

  Further, a backup memory (not shown) is connected to the bus arbiter 44 and records game results and the like. The backup memory may be replaced with system memory (RAM).

  Note that the game device 12 is not limited to a game device installed in an amusement facility 10 or a store such as a game cafe, but a home game device, a personal computer, a portable electronic game machine, a mobile phone, a PDA, or the like. It may be an electronic device or a game information processing device.

(Run game)
First, the player sits on a chair of the game apparatus 12 provided in the amusement facility 10, and then performs an information reading operation such as inserting, touching, or scanning the member card 16 into the game apparatus 12. The game apparatus 12 reads the ID number from the recorded information by the magnetic means or the electrical means described on the member's card 16. Thereby, the game device 12 can recognize that the player who owns the member's card of the ID number plays the mahjong game.

  Subsequently, the player starts a mahjong game with the game device 12. A game screen is displayed on the display monitor 34 of the game apparatus 12. On this game screen, the characters of the players participating together with the mahjong table are displayed, and the progress of the game is displayed on the mahjong table.

(Game flow)
Next, the flow of the game in the game apparatus 12 according to the present embodiment will be described with reference to screen examples (see FIGS. 4 to 8) displayed on the display monitor 34 and a flowchart (see FIG. 9). Note that “random seed (player seed)” and “indeterminate element” in the following description will be described in detail later.

  When the player touches the touch panel 24 on the screen (display monitor 34) in the game device 12 during the advertisement (advertisement screen) loop (step S200), a screen for selecting either “card use” or “card not used”. (Step S201).

  If the player selects “use card” (YES in step S202), authentication is performed by holding (or scanning) own member card 16 over IC card I / F (interface) 18 (step S203). If the authentication is successful, the screen (display monitor 34) shifts to a credit insertion screen (step S204). On the other hand, if “card not used” is selected in step S201, the process proceeds to the credit insertion screen as it is (step S204).

  When the player touches the game start button on the credit insertion screen, a random number seed (partial random number seed) unique to the player (hereinafter also referred to as “seed” and displayed as “player seed” in the screen) PS It is generated (step S205). Thereafter, the screen shifts to a “play mode selection screen” (step S206). When the player completes the selection of the play mode, the screen shifts to a “matching screen” (step S207).

  On the matching screen, a message indicating that the opponent is being searched (matching), the number of entries at the time, the random number seed (player seed) PS of the player, and the like are displayed (see FIG. 4). In addition, information indicating that “the game is played with the CPU when no opponents are available” can be displayed together (see FIG. 4). If the matching is completed (YES in step S208), the game is started (step S210). On the other hand, if matching is not completed within a predetermined time (NO in step S208), a game (CPU battle) with the computer (CPU 40) is started (step S209). During this CPU battle, matching may be continued behind the scenes (steps S209 and 208).

  When the game is started (step S210), the process proceeds to the main game (step S211). During the main part of the game, “My seed” (player seed specific to the player), “Current value of uncertain elements”, and “History of stations of uncertain elements” are displayed on the screen as necessary. (See FIG. 5). In this embodiment, a seed information display / non-display icon 90 is provided in the normal game screen in the main game (see FIG. 6), and the display / non-display of the seed information is switched according to the touch operation of the player. (See FIGS. 5 and 6). While this “seed information” icon 90 is being touched or until it is touched next time, “own random number seed (player seed)” and “stationary history of indeterminate elements” are displayed. The

  When the game is completed, the game screen shifts to a continue screen displaying the game results together (step S212). On this screen, “all seeds” (player seeds unique to each player) and “history of uncertain elements for each station” are displayed (see FIG. 8). In this embodiment, a seed information display / non-display icon 92 is provided in the continue screen (see FIG. 7) so that the display / non-display of the seed information can be switched according to the player's touch operation. (See FIGS. 7 and 8).

  If any player continues (continuous play) (YES in step S213), a random seed (player seed) PS of the player is generated (step S214), and the process returns to the “matching screen” (step S214). S207). On the other hand, if the game is not continued within the predetermined time, the game is over (step S215), and the process proceeds to the advertise loop.

(Publication of random number seed PS)
In the present embodiment, the following is disclosed (disclosed) to prove that there is no fraud (that the game has progressed fairly without fraud).
(A) Ulsan generation (B) Seats / Dice (C) Random seeds

  Among the above, (A) For Ulsan generation, an algorithm for the Ulsan generation method is disclosed. (B) For the seats and dice, all algorithms for the random elements of the mahjong part, such as place determination, parental determination, dice, etc. are disclosed. (C) The random seed PS is disclosed in a manner that is known to be fraudulent and not misused.

  Proof that there is no cheating can be performed by explaining the flow of the game as follows, for example. That is, (1) the player's random number seed PS is displayed on the opponent search screen (see step S207 in FIG. 9). In this way, by proving in advance, it is proved that there is no retrofitting action. However, since it becomes difficult to confirm if the number of characters is too large, it is preferable to keep the number of characters to an appropriate number while maintaining a sufficient number of characters as the random number seed PS.

  Next, when (2) matching (search and determination of opponents) is completed (YES in step S208 in FIG. 9), the “random number seed” (PS) of each player is combined and used in the game. The seeds (CS). When combining, the “random seed” (PS) of each player may be combined, for example, by rearranging them in ascending order. In short, the player-specific random number seed (player seed) generated for each player should be called “partial random number seed” or “part of random number seed”. If “part” is combined, “all random number seeds” (joined random number seed) is determined. In addition, by concatenating (+0) “0” to “all random number seeds” determined in this way, a new random seed to be reflected in the contents of the first game (for example, East One Station) It is determined. After the game starts, a place and a parent are determined based on the new “random number seed”.

  In addition, (3) during the game, the random number seed (PS) of each player is connected to or added to the uncertain element (UE) to make a new “random seed” (update the “random seed” from time to time) ). The “indeterminate element” should be an indeterminate common random number seed that varies according to the game progress of each player, and is generated separately from the “random seed” (PS) unique to each player. The result of the lottery according to the random number seed is also reflected in the game. “Undetermined elements” are contents that can change depending on the progress of the game, such as the number of items selected by each player (for example, discards discarded from their own field) and numerical values according to the contents. It can be. Such an “indeterminate element” is also a mahjong game in which the content of the next station (or the next station) will change depending on whether to discard A 牌 or B 牌 in actual mahjong. It can function as an element included in In addition, an uncertain element (or a random seed (player seed) PS in which the uncertain element is reflected) can be added to generate an hill, roll a dice, and the like. The current value of the indeterminate element is displayed on the screen together with the random number seed (player seed) PS of the player (self) (step S211 in FIG. 9).

  Furthermore, (4) after the game, the random seeds PS of all players are made public on the screen (see step S212 in FIG. 9, FIG. 8). In addition, the history for each station of the indeterminate element UE is displayed together with the random number seed PS of all players (see FIG. 8). If there is a player who has dropped out or is disconnected from the internet, the seed of random numbers is not disclosed. Depending on the player, the timing at which the match ends may differ, so it becomes possible for the player who finished earlier to assist the player who was present (for example, two fraudsters match the same table and one player ), And it becomes possible to teach another person the seeds of random numbers). In the case of withholding the disclosure in this way, it is preferable to explain the reason to the user in advance. By doing so, it becomes possible to prevent the player and the like from having excessive dissatisfaction and doubt.

  It is desirable that the number of ridges is equal to or more than all the combinations of ridges. In the case of a rule of four players and one red fox (bonus 上 が る that raises a role) one by one, based on the number obtained by dividing all combinations of all 牌 (136) by combinations of the same type 牌Can be set as appropriate (in addition, 4 cocoons without red cocoons and 3 cocoons with red cocoons are the same type of cocoons).

(How to create Ulsan)
In the present embodiment, randomness is satisfied as described below when generating a mountain.

  <Randomness> The seed of the random number used in each station is “random seed generated in advance of the game (player seed)” + “indeterminate element”. As described above, every time a station is terminated, the uncertain element UE is connected (added) to the seed of the random number and updated. In this case, since the uncertain element UE is an indeterminate common random number seed that varies depending on the game progress, the random seed connected to the uncertain element UE is also an uncertain element that varies each time. . There is a problem if the foot of each station has a law, but in this embodiment, when the result of the lottery according to the seed of random numbers is reflected in the game, a game signal having no law (randomness) is generated. It has been realized.

  <Disclosure of Algorithm> Prior to the game, the algorithm of the Ulsan generation method is disclosed to a player or the like. As a means for disclosure, there is a method that can provide information at any time in response to a request from a player, for example, to publish a website including the information. As an example, FIG. 5 shows that the generation logic of Ulsan is disclosed on the web page and the URL together with the seed information described above (see FIG. 5). The algorithm according to the present embodiment represents “how to draw a random number from a seed of random numbers and reflect it in a game (such as Ulsan or dice)”. In this embodiment, the algorithm is described by publishing the source program.

  Even if only the source program is released, normal users cannot confirm it. Therefore, although not explained in detail, when a random number seed is input, an application that displays the eyes of Ulsan or dice (for example, software that can be installed for a mobile terminal) is used to replay the play result of the game. It may be possible to easily perform the confirmation work.

  Although not specifically described in detail, the game system 1 may be provided with a function for providing an algorithm or information related thereto to a terminal such as a mobile phone or a PC owned by the player. For example, a random number seed (player seed) PS and an indeterminate element (common random seed) after the game is stored in the play data management server 30 described above, and the stored random seed (player seed) It is possible to record or transmit data relating to PS and uncertain factors to a terminal, or to allow reference to the data from the terminal under certain conditions. Furthermore, in addition to the algorithm, a function for confirming Ulsan by inputting a seed of random numbers or an indeterminate element may be added as a function of the game score viewer. For example, it is desirable to disclose algorithms for all random elements in the progress of the mahjong game, such as seats, dice, place decision, parent decision, and the like.

  <Example of algorithm> (see FIG. 10) As an algorithm for generating yam, the random seed (player seed) PS of each player is connected, and the random number seed is determined by adding the indeterminate element UE as described above. Finalize. Set the yam as an initial value in order, and use the completed random number seed to perform an operation to randomly swap all the yam. Depending on the random number used, the yam is replaced in several steps. For example, if the completed random number seed is 640 bits and the random number seed to be used is 128 bits long, the loop will be 640/128 times.

  According to the present embodiment, in a mahjong game in which a CPU (computer) 40 randomly draws and distributes a kite to each player based on the lottery result, dissatisfaction and doubt about fairness that the player may have Can do. In other words, demonstrating the fairness of the generation of yam, "Computer mahjong is involved in illegal acts such as involvement and control by game makers and service providers, etc." When there is a reputation, winds, rumors, etc., or there are players who think that way, games such as game makers in the game using a random seed (player seed) PS You can prove that there is no room to work and that the game progress is being carried out fairly. Thus, the game system 1 of this embodiment mounts CPU40 in the state which guaranteed systematically that no artificial operation is performed in the production | generation of a yam etc., and eliminates such user dissatisfaction. . Accordingly, it is possible to provide a sense of security to game enthusiasts and users, such as players who have a negative opinion such as dissatisfaction or doubt about the computer mahjong game, increase motivation to play, and serve to deter player separation.
