     In this arrangement, concurrently run are a base game offering a chance of winning a payout according to a predetermined combination and a chance game offering a chance of obtaining a chance flag which qualifies a player to join a special game offering a chance of winning a higher payout than the base game. A payout is determined according to a result of the base game and is awarded. In accordance with a result of the chance game, there is determined whether or not a chance flag is awarded. When a chance flag is awarded, the number of awarded chance flags is stored in the chance flag memory, in association with a timing of awarding the chance flag specified by the timer. Based on a timing at which the chance flag is awarded, a timing to run a special game is determined. An image based on the timing to run the special game is displayed on the display. At the timing to run the special game, the special game is run in which a player participates by consuming the chance flag stored in the chance flag memory. A rank is determined according to a result of the special game. A payout of the special game is determined according to the determined rank and the timing to run the special game. The determined payout of the special game is awarded. 
     In this way, a payout of a special game is determined by a rank determined according to a result of the special game and the timing to run the special game. This provides a player with a new entertainment characteristic.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following describes an embodiment of a gaming machine and a playing method thereof according to the present invention. 
     As illustrated in  FIG. 1 , the gaming machine is structured so that a payout as a result of a JP game which is a special game is determinable by a rank which is determined according to a result of the special game and a timing to run the special game. 
     More specifically, the gaming machine includes: a base game configured to award a payout according to a predetermined combination; a JP game configured to award a higher payout than the base game; a chance game configured to provide a JP chance qualifying a player to join the JP game; a timer which specifies a timing at which a JP chance is awarded; a JP chance memory which stores the number of awarded JP chances in association with the timings; a display which displays an image based on a JP chance and a timing; and a controller programmed to operate as described in the following (a1) through (a10). 
     A step (a1) is configured to concurrently run a base game and a chance game. A step (a2) is configured to determine and award a payout according to a result of the base game. A step (a3) is configured to determine whether to award a JP chance based on a result of the chance game. A step (a4) is configured to store, when a JP chance is awarded, the number of awarded JP chances in the JP chance memory, in association with a timing of awarding the JP chance specified by the timer. A step (a5) is configured to determine a timing to run a JP game, based on the timing of awarding the JP chance. A step (a6) is configured to display on the display an image based on the timing to run the JP game. A step (a7) is configured to execute, at the timing to run the JP game, the JP game which requires a player to consume a JP chance stored in the JP chance memory to participate in the game. A step (a8) is configured to determine a rank according to a result of the JP game. A step (a9) is configured to determine a payout of the JP game according to the determined rank and the timing to run the JP game. A step (a10) is configured to award the determined payout of the JP game. 
     That is to say, the gaming machine executes a playing method including the steps of: running a base game and a chance game at the same time; determining and awarding a payout according to a result of the base game; determining whether to award a JP chance, based on a result of the chance game; if a JP chance is awarded, storing in the JP chance memory the number of awarded JP chances, in association with a timing at which the JP chance is awarded, specified by the timer; determining a timing to run a JP game according to the timing to award the JP chance; displaying on the display an image according to the timing to run the JP game; running, at the timing to run the JP game, a JP game in which a player participates by consuming a JP chance stored in the JP chance memory; determining a rank according to a result of the JP game; determining a payout of the JP game according to the determined rank and the timing to run the JP game; and awarding the thus determined payout of the JP game. 
     In this way, a payout of a JP game is determined by a rank determined according to a result of the JP game and the timing to run the JP game. This provides a player with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the display, a player is motivated to continue a game thanks to decreased stress on him/her. 
     A gaming machine  1  of the present embodiment includes gaming terminals  10 . A player is able to play a base game and a chance game at each gaming terminal  10 . A player is also allowed to participate in a JP game which is concurrently run at all of the gaming terminals  10 . The gaming machine may be a multiplayer type as in this embodiment or a single-player type. Also, the gaming machine may be structured such that gaming machines such as slot machines, each of which presupposes an independent player, are connected to be able to exchange data, so as to form a multiplayer gaming machine as a whole. 
     Examples of the display of the present invention include a liquid crystal display device, a CRT (cathode-ray tube) device, a plasma display device, and an organic EL (Organic Electro-Luminescence) display device. As for the display, each gaming machine may have a single display or plural displays. In case of multiplayer type, each slot machine may be provided with a display, or a large display shared by all gaming machines may be provided independently of the gaming machines. Specifically, the gaming machine  1  of the present embodiment includes a single shared display  203  and terminal displays  101  of the respective gaming terminals  10 . The shared display is disposed to be viewable from each gaming terminal  10 . 
     “Base game” is a main game of each gaming machine, and a player primarily plays this game. A player bets a predetermined game value to play the base game, and the player is awarded a payout when obtaining a predetermined result from the base game. In this embodiment, a base game is a so-called slot game arranged so that symbols are variably displayed and a payout is awarded according to a stop result of varying display 
     Specifically, “base game” of this embodiment is arranged such that several base symbols  180  are rearranged on respective base symbol arrangement areas  150   a  which are matrix-configured, and a state advantageous for a player is achieved when at least a predetermined number of base symbols  180  are displayed on the matrix. For example, the advantageous states include: a state where a payout is awarded, a state where the number of payout is added to a credit, and a state where a bonus game starts. 
     “Chance game” is a game to obtain a JP chance with which a player is able to qualify a JP game. In this embodiment, “chance game” is the same type of slot game as base game, and is playable at the same time as base game. 
     Specifically, “chance game” of this embodiment is a game in which JP symbols  180 J are rearranged in JP symbol arrangement areas  150   b  which are matrix-configured, at the same time the base symbols  180  are rearranged in the base game. When the JP symbols  180 J rearranged in the matrix-configured JP symbol arrangement areas  150   b  meet a winning condition, a JP chance is awarded. 
     Not limited to the slot game, the base game and the chance game may be roulette, horse racing, boat racing, or bicycle racing. 
     “JP game” is a special game which is run by a later-detailed controller  100  at the same time in two or more gaming terminals  10  at a predetermined time interval. When this JP game results in a jackpot, a higher payout than a payout awarded from the base game is awarded. The JP game is run at a predetermined timing such as every 30 minutes or the like, and is run only for gaming terminals  10  having obtained at least a predetermined number (e.g. one) of JP chances. In this embodiment, the JP game is a virtual “Fishing Tournament” played by players who have obtained JP chances. The players playing the JP game are able to see their selected characters fishing on the shared display  203 . 
     The “arrangement” in this embodiment means a state where the base symbols  180  and JP symbols  180 J can be visually observed by a player. That is, as shown in  FIG. 3 , “arrangement” means that the base symbols  180  are displayed in the base symbol arrangement areas  150   a , and the JP symbol  180 J are displayed in the JP symbol arrangement areas  150   b . Arranging the base symbols  180  and the JP symbols  180 J again after dismissing them is referred to as “rearranging”. 
     Base symbols  180  are symbols used in a base game in each gaming terminal  10 . For each base symbol various types of winning combinations are determined in advance. A winning combination is a combination of base symbols  180  stopping at a payline A, with which a state advantageous for a player is achieved. For example, the advantageous states include: a state where coins corresponding to scatter symbols are paid out, a state where the number of coins to be paid out is added to a credit, and a state where a bonus game is started. The payline L will be discussed later. 
     Further, the “JP symbols 180J” are scatter symbols, which are used in a chance game in each of the gaming terminals  10 . 
     Each of the “scatter symbols” is a symbol whose arrangement results in a winning irrespective of any other conditions. In the present embodiment, a player is awarded a JP chance if at least a predetermined number (e.g. 3) of JP symbols  180 J which are scatter symbols are arranged on the matrix  156 . 
     The “JP chance” qualifies a player to join the JP game. For each JP chance, a process of determining whether or not a jackpot is awarded is performed once. 
     “Jackpot” is awarded in the following way. A part of a game value bet by a player in each base game is subtracted and the subtracted parts are accumulated as a progressive value. When a player wins a JP game, he/she is awarded a part of or all of the accumulated progressive value. 
     As illustrated in  FIG. 1 , the gaming machine may be structured so that, comparing two players in the same rank, a player for whom the JP game is run earlier than for the other player obtains a higher payout than the other player. 
     More specifically, the gaming machine includes: gaming terminals each capable of independently running a game; a base game configured to award a payout according to a predetermined combination; a JP game configured to award a higher payout than the base game, in which game the gaming terminals participates in turn; a chance game configured to provide a JP chance qualifying a player to join the JP game; a timer which specifies a timing to award a JP chance; a JP chance memory which stores the number of awarded JP chances, in association with the timing to award the JP chance; a display which displays an image according to the JP chance and the timing; a result memory which stores a rank according to a result of a JP game and a payout in association with one another; and a controller programmed to operate as described in the following (b1) through (b10). 
     A step (b1) is configured to concurrently run a base game and a chance game in each gaming terminal. A step (b2) is configured to determine and award a payout according to a result of the base game. A step (b3) is configured to determine whether to award a JP chance according to a result of a chance game. A step (b4) is configured to store, when a JP chance is awarded, the number of awarded JP chances in the JP chance memory for each gaming terminal, in association with a timing of awarding the JP chance specified by the timer. A step (b5) is configured to determine a timing to run a JP game, based on the timing of awarding the JP chance. A step (b6) is configured to display on the display an image based on the timing to run the JP game. A step (b7) is configured to execute, at the timing to run the JP game, the JP game which requires a player to consume a JP chance stored in the JP chance memory to participate in the game. A step (b8) is configured to determine a rank according to a result of the JP game. A step (b9) is configured to determine, when the result memory stores a result in the same rank as the determined rank, a payout of the JP game to be lower than the payout in the result memory. A step (b10) is configured to store in the result memory the determined payout of the JP game in association with the determined rank, and award the determined payout of the JP game. 
     As a result of the above, a payout of a JP game is determined by a rank determined according to a result of the JP game and a timing to run the JP game. Specifically, comparing two players in the same rank, a player for whom the JP game is run earlier than for the other player obtains a higher payout than the other player. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the display, a player is motivated to continue a game thanks to decreased stress on him/her. 
     As illustrated in  FIG. 1 , the gaming machine may be structured so that a payout awarded as a result of a JP game is determined according to (i) a rank determined by the result of the JP game, (ii) a timing to run the JP game, and (iii) a game value accumulatively stored in the payout memory. 
     More specifically, the gaming machine includes: a base game which is executed in response to the consumption of a predetermined game value and is configured to award a payout according to a predetermined combination; a payout memory which accumulatively stores a part of the consumed game value as a JP game payout; a JP game configured to award a higher payout than the base game; a chance game configured to provide a JP chance qualifying a player to join the JP game; a timer which specifies a timing to award a JP chance; a JP chance memory which stores the number of awarded JP chances, in association with the timing to award the JP chance; a display which displays an image according to the JP chance and the timing; and a controller programmed to operate as described in the following (c1) through (c11). 
     A step (c1) is configured to concurrently run a base game and a chance game. A step (c2) is configured to store a part of the consumed game value in the payout memory. A step (c3) is configured to determine and award a payout according to a result of the base game. A step (c4) is configured to determine whether to award a JP chance, according to a result of the chance game. A step (c5) is configured to store, when a JP chance is awarded, the number of awarded JP chances in the JP chance memory, in association with a timing of awarding the JP chance specified by the timer. A step (c6) is configured to determine a timing to run a JP game, based on the timing of awarding the JP chance. A step (c7) is configured to display on the display an image based on the timing to run the JP game. A step (c8) is configured to execute, at the timing to run the JP game, the JP game which requires a player to consume a JP chance stored in the JP chance memory to participate in the game. A step (c9) is configured to determine a rank according to a result of the JP game. A step (c10) is configured to determine a payout of the JP game according to (i) the determined rank, (ii) the timing to run the JP game, and (iii) the game value accumulatively stored in the payout memory. A step (c11) is configured to award the determined payout of the JP game. 
     In this way, a payout of a JP game is determined by a rank determined according to a result of the JP game, the timing to run the JP game, and a game value accumulatively stored in the payout memory. This provides a player with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the display, a player is motivated to continue a game thanks to decreased stress on him/her. 
     As illustrated in  FIG. 1 , the gaming machine may be structured as follows: a payout of a JP game is determined according to (i) the determined rank, (ii) the timing to run the JP game, and (iii) the game value accumulatively stored in the payout memory, with the result that, comparing two players in the same rank, a player for whom a JP game is run earlier obtains a higher payout than the other player. 
     More specifically, the gaming machine includes: gaming terminals each capable of independently running a game; a base game which is executed in response to the consumption of a predetermined game value and is configured to award a payout according to a predetermined combination; a payout memory which accumulatively stores a part of the consumed game value as a JP game payout; a JP game configured to award a higher payout than the base game, in which game the gaming terminals participates in turn; a chance game configured to provide a JP chance qualifying a player to join the JP game; a timer which specifies a timing to award a JP chance; a JP chance memory which stores the number of awarded JP chances, in association with the timing to award the JP chance; a display which displays an image according to the JP chance and the timing; a result memory which stores a rank according to a result of a JP game and a payout in association with one another; and a controller programmed to operate as described in the following (d1) through (d11). 
     A step (d1) is configured to concurrently run a base game and a chance game in each gaming terminal. A step (d2) is configured to store in the payout memory a part of the consumed game value. A step (d3) is configured to determine and award a payout according to a result of the base game. A step (d4) is configured to determine whether to award a JP chance, according to a result of the chance game. A step (d5) is configured to store, when a JP chance is awarded, the number of awarded JP chances in the JP chance memory for each gaming terminal, in association with a timing of awarding the JP chance specified by the timer. A step (d6) is configured to determine a timing to run a JP game, based on the timing of awarding the JP chance. A step (d7) is configured to display on the display an image based on the timing to run the JP game. A step (d8) is configured to execute, at the timing to run the JP game, the JP game which requires a player to consume a JP chance stored in the JP chance memory to participate in the game. A step (d9) is configured to determine a rank according to a result of the JP game. A step (d10) is configured to determine, when a result in the same rank as the thus determined rank is stored in the result memory, a payout of the JP game to be lower than the payout of the result in the result memory, in accordance with the game value accumulatively stored in the payout memory. A step (d11) is configured to store, in the result memory, the determined payout of the JP game in association with the determined rank, and award the determined payout of the JP game. 
     In this way, a payout of a JP game is determined by (i) a rank determined according to a result of the JP game, (ii) the timing to run the JP game, and a game value accumulatively stored in the payout memory. Specifically, comparing two players in the same rank, a player for whom the JP game is run earlier than for the other player obtains a higher payout than the other player. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the display, a player is motivated to continue a game thanks to decreased stress on him/her. 
     (Function Blocks of Gaming Machine) 
     As illustrated in  FIG. 2 , the gaming machine configured as above has the shared display  203 , the controller  100 , and the gaming terminals  10 . 
     (Shared Display  203 ) 
     The shared display  203  displays, as illustrated in  FIG. 1 , a virtual “Fishing Tournament” which is a JP game. The structure of the shared display  203  will be specifically discussed later. 
     (Gaming Terminal  10 ) 
     As illustrated in  FIG. 2 , each of the gaming terminals  10  includes a terminal display  101 , a game starting unit  110 , and a BET unit  111 . 
     The terminal display  101  has a function of displaying a notifying image and an effect image for a base game and/or a chance game. The terminal display  101  includes base symbol arrangement areas  150   a  where base symbols  180  are arranged and JP symbol arrangement areas  150   b  where JP symbols are arranged. The game starting unit  110  has a function of outputting a game start signal in response to an operation by a player. The output game start signal is supplied to a later-detailed game running unit  103 . The BET unit  111  has functions of receiving a BET in response to an operation by a player and outputting a BET signal. The output BET signal is supplied to the later-detailed game running unit  103 . 
     (Controller  100 ) 
     As shown in  FIG. 2 , the controller  100  includes: a game running unit  103 , a symbol memory  108 , a timer  228 , a JP chance memory  109 , a display memory  107 , and a display control unit  102 . 
     The game running unit  103  runs a base game, triggered by the game start signal from the game starting unit  110 . The base game is a game in which base symbols  180  are rearranged in the base symbol arrangement areas  150   a  of the terminal display  101 . At the same time of running the base game, the game running unit  103  also runs a chance game in which JP symbols  180 J are rearranged in the JP symbol arrangement areas  150   b  of the terminal display  101 . 
     The symbol memory  108  stores the base symbols  180  and JP symbols  180 J. The timer  228  specifies a timing at which a JP chance is awarded. The JP chance memory  109  functions as a chance flag memory which stores, for each gaming terminal  10 , the number of JP chances awarded to a player in association with the timing of awarding the JP chance specified by the timer  228 . The display memory  107  stores, as symbols to be displayed, the base symbols  180  and JP symbols  180 J in the symbol memory  108 . In addition, the display memory  107  stores effect image data for a base game and a chance game. 
     The display control unit  102  performs setting so that the base symbol arrangement areas  150   a  for arranging therein the base symbols  180  overlap the JP symbol arrangement areas  150   b  for arranging therein the JP symbols. Further, the display control unit  102  reads out base symbols  180  from the display memory  107  and displays the base symbols  180  in the base symbol arrangement areas  150   a , under the control of the game running unit  103 . The display control unit  102  also reads out JP symbols  180 J from the display memory  107  and displays the JP symbols  180 J in the JP symbol arrangement areas  150   b , under the control of the game running unit  103 . 
     The controller  100  includes a base game payout determining unit  105 , a JP chance determining unit  106 , and a payout awarding unit  104 . 
     The base game payout determining unit  105 , under the control of the game running unit  103 , determines whether to award a payout of a base game on the basis of the relations among the base symbols  180  rearranged in the base symbol arrangement areas  150   a . If it is determined that the payout is awarded, the base game payout determining unit  105  determines an amount of the payout and outputs a signal to the payout awarding unit  104 . 
     The JP chance determining unit  106 , under the control of the game running unit  103 , determines whether to award a JP chance on the basis of the relations among the JP symbols  180 J rearranged in the JP symbol arrangement areas  150   b . If it is determined that a JP chance is awarded, the JP chance determining unit  106  determines the number of JP chances and outputs a signal to the JP chance memory  109 . 
     The payout awarding unit  104  awards the payout of the base game determined by the base game payout determining unit  105 . Further, the payout awarding unit  104  awards a payout of a JP game determined by a later-detailed JP game result determining unit  227 , in response to a signal from the JP game result determining unit  227 . Note that a JP game is run when the number of JP chances stored in the JP chance memory  109  for each gaming terminal equals or surpasses a predetermined number. Further, an amount of the payout of the JP game is determined by the later-detailed JP game result determining unit  227 . 
     The controller  100  further includes: a JP game running unit  224 , a JP order determining unit  229 , a JP game memory  223 , a JP game screen memory  222 , and a shared display control unit  221 . 
     The JP game running unit  224  determines, when predetermined time comes, whether the JP chance memory  109  stores a predetermined number or more of JP chances. This determination is made for each gaming terminal  10 . The JP game running unit  224  runs a JP game on a gaming terminal  10  which stores the predetermined number or more of JP chances. 
     The JP order determining unit  229  determines the order in which gaming terminals participate in a JP game, based on a timing at which a JP chance is awarded. In other words, the JP order determining unit  229  determines in what order a result of a JP game is notified to the gaming terminals  10 , based on a timing of awarding a JP chance. 
     In the present embodiment, the order in which a result of a JP game is notified to gaming terminals  10  is referred to as the order of participation in a JP game. 
     The JP game memory  223  stores therein information regarding the JP game. For example, the JP game memory  223  stores image data which is used for displaying, on the shared display  203 , a line image arranged in a predetermined area and pointer images which indicate respective gaming terminals, arranged in accordance with the order of participation in a JP game, and move toward the line image. The JP game screen memory  222  stores therein display information based on the information of the JP game stored in the JP game memory  223 . 
     The shared display control unit  221 , under the control of the JP game running unit  224 , reads out from the JP game screen memory  222  the display information which is based on the content of the JP game, and causes the shared display  203  to perform image displaying based on the display information. 
     The shared display control unit  221  causes the shared display  203  to display an image based on the order in which the gaming terminals  10  participate in a JP game, which has been determined by the JP order determining unit  229 . Specifically, pointer images indicating the respective gaming terminals are arranged on the shared display  203  in accordance with the order of participation in a JP game, and these pointer images move toward a line image arranged in a predetermined area. This enables the players to visually and easily understand the order of participation in the JP game and also understand when the players participate in the JP game. 
     In addition to the above, the controller  100  includes a JP game result storage unit  230 , a JP game result determining unit  227  and a progressive memory  226 . 
     The JP game result storage unit  230  stores a rank determined by the JP game result determining unit  227  and a determined payout amount in association with one another. 
     Based on a result of a JP game, the JP game result determining unit  227  determines whether to award a payout of the JP game, under the control of the JP game running unit  224 . In other words, whether a jackpot is met is determined. When it is determined that a jackpot is met, the JP game result determining unit  227  determines the rank of the payout (e.g. from four ranks). The JP game result determining unit  227  determines an amount of the payout according to the determined rank. The determination of whether a payout of a JP game is to be awarded is conducted for a number of times equal to the number of JP chances which each gaming terminal  10  has. 
     In case where the JP game result storage unit  230  stores a JP game result whose rank is identical with the rank determined by the JP game result determining unit  227 , the JP game result determining unit  227  determines the payout of the JP game to be lower than the payout amount stored in the JP game result storage unit  230 . 
     Ranks in this case are used for setting a payout. Specifically, a rank may be a ratio to a progressive value stored in the progressive memory  226  or a specific payout amount. For example, when ranks are ratios to a progressive value, the first rank is 50% of the progressive value, the second rank is 20% of the progressive value, the third rank is 5% of the progressive value, the fourth rank is 1% of the progressive value, and so on. In another example, when ranks indicate specific payout amounts, the first rank indicates 10,000 dollars, the second rank indicates 4,000 dollars, the third rank indicates 1,000 dollars, the fourth rank indicates 200 dollars, and so on. Alternatively, the determination of whether to award a payout of a JP game may be omitted, including a case where no payout is assigned to a rank. For example, the fourth rank may indicate “no payout”. In addition to the above, ranks may indicate predetermined ranges, respectively. For example, the first rank indicates a range of 40 to 50% of the progressive value. 
     The progressive memory  226  accumulatively stores a progressive value indicated by a progressive signal received from the controller  100 . The progressive signal is transmitted from each gaming terminal  10  for the purpose of storing, as a payout of a JP game, a part of a game value consumed in a base game in the progressive memory  226 . 
     Each block of the controller  100  may be realized with hardware or with software as needed. 
     (Operation of Controller  100 ) 
     The following describes an operation of the controller  100  in the above structure. First, the BET unit  111  receives a BET entered through an operation by a player. Further, a game start signal is output from the game starting unit  110  in response to the player&#39;s operation, and a base game and a chance game are run at the same time by the game running unit  103 . When both of the games are run at the same time, the display control unit  102 , under the control of the game running unit  103 , displays base symbols  180  in the base symbol arrangement areas  150   a . The display control unit  102  also displays JP symbols  180 J in the JP symbol arrangement areas  150   b , under the control of the game running unit  103 . 
     Further, the base game payout determining unit  105  determines whether a payout is awarded, based on relations among the base symbols  180  rearranged in the base symbol arrangement areas  150   a . If it is determined that a payout is awarded, the base game payout determining unit  105  determines an amount of the payout. The payout thus determined of the base game is awarded by the payout awarding unit  104 . 
     The JP chance determining unit  106  determines whether to award a JP chance on the basis of the relations among the JP symbols  180 J rearranged in the JP symbol arrangement areas  150   b . If it is determined that JP chance is awarded, the JP chance determining unit  106  determines the number of JP chances to be awarded and stores the JO chance in the JP chance memory. 
     When the number of JP chances is stored in the JP chance memory, the JP chance determining unit  106  stores the number of JP chances in association with the timing specified by the timer  228 . When the number of gaming terminals  10  is two or more, the number of JP chances may be stored in association with each gaming terminal  10 . 
     At a predetermined timing, the JP game running unit  224  checks, for each gaming terminal  10 , whether the JP chance memory  109  stores a JP chance. When there is a gaming terminal  10  storing a JP chance, a JP game is run at a gaming terminal  10  having a predetermined number or more of JP chances. Alternatively, it is possible to randomly determine the timing at which whether or not a JP chance is stored is determined and the JP game is run at a gaming terminal having a predetermined number or more of JP chances. Also, the timing at which the JP game starts may be notified by using the terminal display  101  or the like. 
     Then the JP game result determining unit  227  determines whether a jackpot is met, based on a result of the JP game. If it is determined by the JP game result determining unit  227  that a jackpot is met, the JP game result determining unit  227  determines the rank of the payout. The JP game result determining unit  227  checks whether a JP game result in the same rank is stored in the JP game result storage unit  230 . If there is a JP game result in the same rank, a payout of the JP game is determined to be lower than the payout amount stored in the JP game result storage unit  230 , based on the rank thus determined. 
     The determination of whether a jackpot is met and the determination of an amount of payout for the jackpot may be carried out when the JP game is run or when a JP chance is awarded to the player (i.e. when a JP chance is stored in the JP chance memory  109 ). 
     When the gaming machine is structured to include more than one gaming terminals  10 , the JP order determining unit  229  determines the order in which the gaming terminals  10  participate in a JP game, based on a timing of awarding a JP chance. 
     Furthermore, the shared display  203  displays an image based on a timing to run a JP game. For example, the shared display  203  displays a pointer image which is arranged at a part corresponding to a timing to run a JP game and which moves toward a line image arranged in a predetermined area. In addition to the above, the shared display  203  notifies a result of a JP game in which a player participates by consuming a JP chance stored in the JP chance memory  109 , in accordance with a timing at which the pointer image reaches the line image. Alternatively, the shared display  203  may display images based on the order in which the gaming terminals  10  participates in a JP game, which order has been determined by the JP order determining unit  229 . Alternatively, the aforesaid arrangements may be combined. 
     When the result of the JP game is notified, the payout awarding unit  104  awards a payout of the JP game. 
     (Display States) 
     Now, the following discusses an example where the gaming machine is specifically embodied as a gaming machine  1 . 
     A gaming machine  1  is placed in a gaming facility such as a casino. This gaming machine  1  runs a unit game which involves a game medium. The game medium is a coin, bill, or a value in the form of electronic information. However, the game medium in the present invention is not particularly limited. For example, a medal, token, electronic money, ticket or the like are also possible. Further, the ticket is not particularly limited and may be a later-described ticket with a barcode or the like ticket. 
     As illustrated in  FIG. 8 , the gaming machine  1  includes: gaming terminals  10  which run a base game independently from each other (the number of gaming terminals  10  is  4  in the present embodiment); a center control unit  200  connected to the gaming terminals  10 , which is in communication with the gaming terminals  10  and runs a JP game; a shared display  203  which displays thereon an effect image related to the JP game; a rail  271  which allows the shared display  203  to move to a position immediately above one of the gaming terminals  10 ; and a not-illustrated drive motor  270 . 
     In addition, each gaming terminal  10  has an upper image display panel  33  and a lower image display panel  16 . The lower image display panel  16  and the upper image display panel  33  function as the above-discussed terminal display  101 . A payout of a JP game is configured to be higher than that of a base game. 
     (Display States of Lower Image Display Panel  16 ) 
     Now, referring to  FIG. 3 , the display states of the lower image display panel  16  in a base game and a chance game are specifically described. The lower image display panel  16  is structured to arrange symbols in accordance with video reel. The lower image display panel  16  may have a mechanical structure adopting a reel device which rotates a reel to arrange symbols. Alternatively, the lower image display panel  16  may have an electric structure in which symbols are arranged by a video reel displayed as an image. Further, the lower image display panel  16  may adopt a combination of the mechanical structure (reel) and the electrical structure (video reel). 
     As shown in  FIG. 3 , the lower image display panel  16  displays a matrix-configured matrix  156 , when a base game and a chance game are run at the same time. The matrix  156  is displayed at the center of the lower image display panel  16 , and base symbols  180  and JP symbol  180 J are arranged therein. Further, the matrix  156  is provided with display windows  151  to  155 . In the display windows  151  to  155 , a symbol column having base symbols  180  and a symbol column having JP symbols  180 J are scrollably displayed. These columns overlap each other. The display windows  151  to  155  are respectively divided into upper stages  151   a  to  155   a , central stages  151   b  to  155   b , and lower stages  151   c  to  155   c . The base symbols  180  and the JP symbols  180 J are stopped (arranged) in each of the stages  151   a  to  155   a ,  151   b  to  155   b , and  151   c  to  155   c  so that a base symbol  180  overlaps a JP symbol  180 J. 
     For example, in  FIG. 3 , a “Clownfish”  181  which is a base symbol  180  is stopped in a base symbol arrangement area  150   a  in the upper stage  151   a  of the display window  151 , and a “GET” which is a JP symbol  180 J is stopped in the JP symbol arrangement area  150   b  of the same stage. Further, an “Angelfish”  182  is stopped in the base symbol arrangement area  150   a  in the central stage  151   b  of the display window  151 , and no symbol is stopped in the JP symbol arrangement area  150   b  of the same stage. Further, a “Clownfish” is stopped in the base symbol arrangement area  150   a  in the bottom stage  151   c  of the display window  151 , and a “GET” which is a JP symbol  180 J is stopped in the JP symbol arrangement area  150   b  of the same stage. In short, the matrix  156  is a symbol matrix including five columns and three rows. The matrix  156  however is not limited to the one with the five-columns and three-rows. 
     In the upper-right part of the lower image display panel  16 , a JP chance display area  160  is displayed as illustrated in  FIG. 3 . JP chance display area  160  displays the number of JP chances that a player currently has. For example, in  FIG. 3 , the number of JP chances is “1”. As such, a player is able to join the JP game only once to be subjected to a process of determining whether a payout is awarded. 
     As illustrated in  FIG. 3 , the base symbols  180  and the JP symbols  180 J are arranged so as to overlap one another in the lower image display panel  16 , when a base game and a chance game are run at the same time in the gaming terminal  10 . Specifically, as shown in the lower part of  FIG. 3 , a JP symbol  180 J is arranged in the JP symbol arrangement area  150   b  below each base symbol arrangement area  150   a.    
     As such, the base symbols  180  and the JP symbols  180 J are concurrently arranged on the matrix  156  in the lower image display panel  16  to indicate results of a base game and a chance game. In this way a base game and a chance game can be run at the same time. 
     In a base game, base symbols  180  are arranged and a payout is awarded in accordance with the arrangement of the base symbols  180 . In the case of  FIG. 3 , “Clownfish”  181  which is a base symbol  180  is displayed in each of the upper stage  151   a  of the display window  151 , the upper stage  152   a  of the display window  152 , and the upper stage  153   a  of the display window  153 . As a result of this, a winning combination of “Clownfish”  181  is met in the base game, and a payout according to this winning combination is awarded. 
     In a chance game, arranged are only JP symbols  180 J. In the case of  FIG. 3 , “GET” is displayed in each of the upper stage  151   a  of the display window  151 , the lower stage  151   c  of the display window  151 , the lower stage  153   c  of the display window  153 , and the central stage  154   d  of the display window  154 . As a result of the above 4 JP symbols are arranged. In the present embodiment, a JP chance is awarded when three or more JP symbols  180 J are arranged. Therefore the number of JP chance is increased in the case above. As the number of JP chances is increased, the JP chance display area  160  is updated. 
     Because of the above, the gaming machine  1  provides a new entertainment characteristic of allowing a player to play a chance game as well as a base game at the same time. 
     As illustrated in  FIG. 4 , the lower image display panels  16  of the respective gaming terminals  10  (gaming terminals  10   a - 10   d ) participating in a JP game display character images  162  ( 162   a - 162   d ) associated with the respective gaming terminals  10 . The character images  162  depict different characters which are fishing and correspond to the respective gaming terminals  10 . 
     JP game is run at a predetermined timing. The JP game however is not run for a gaming terminal  10  having no JP chances. For example, the gaming terminal  10   c  is running not a JP game but a base game, in the case of  FIG. 4 . On the other hand, a JP game is run in each of the remaining 3 gaming terminals  10  (gaming terminal  10   a , gaming terminal  10   b , and gaming terminal  10   d ). 
     For gaming terminals  10  not participating in the JP game, no character image  162  is displayed. For example, in  FIG. 4  the gaming terminal  10   c  cannot participate in the JP game because no JP chance has been awarded thereto. Therefore the lower image display panel  16  of the gaming terminal  10   c  does not display a character image  162 . 
     When a JP game is run, the lower image display panels  16  display comment images  163  in the vicinity of the character images  162 , in the temporal order of obtaining JP chances. Each comment image  163  shows a comment of a character image  162  in such a way that a text “Hit!” is shown in a speech bubble area. For instance, as illustrated in  FIG. 4  and the upper part of  FIG. 5 , when the gaming terminal  10   b  has a turn in a JP game, a comment image  163  is displayed in the vicinity of the character image  162   b  displayed on the lower image display panel  16  of the gaming terminal  10   b.    
     In this way, a comment image  163  is displayed in the vicinity of the character image  162  associated with each gaming terminal  10 . A player can therefore understand that his/her turn has come in a JP game. 
     Thereafter the gaming terminal  10  for which the comment image  163  is displayed is notified of a rank and a payout amount as a result of the JP game. The result of the JP game is one of four ranks of payout. Specifically, the ranks are “Grand Jackpot”, “Major Jackpot”, “Mini Jackpot”, and “Lose”, in the descending order of payout amounts. 
     Specifically, “Grand Jackpot” is a rank in which 40% of an accumulative progressive value is awarded as a result of a JP game. “Major Jackpot” is a rank in which 10% of an accumulative progressive value is awarded as a result of a JP game. “Mini Jackpot” l is a rank in which 5% of a progressive value is awarded as a result of a JP game. No payout is awarded in the case of “Lose”. 
     It is noted that a progressive value is assumed to be 1000 dollars even if the progressive value is actually less than 1000 dollars. Because of this, 200 dollars are awarded even when a jackpot which has been met is “Mini Jackpot”, and hence a player may be motivated to continue the game. 
     Referring to  FIG. 5 , a result of a JP game displayed on the lower image display panel  16  is discussed. The lower image display panel  16  displays, as a result of a JP game, a character image  162 , a payout image  164 , a rank image  168 , and a payout amount image  169 . 
     The rank image  168  is a text image indicating a determined rank. The payout amount image  169  is a text image indicating a payout amount determined according to the determined rank. The payout image  164  is an image of a fish which changes in accordance with the rank. 
     The lower part of  FIG. 5  shows a state of a result of a JP game, which is displayed on the lower image display panel  16  of the gaming terminal  10   b . Displayed on the upper-left screen in the lower part of  FIG. 5  is a display state of the lower image display panel  16  when the rank “Grand Jackpot” results from a JP game. As shown in the upper-left screen in the lower part of  FIG. 5 , as a payout image  164  corresponding to the rank “Grand Jackpot”, a payout image  164   a  showing a marlin is displayed with a character image  162   b . The upper-right screen in the lower part of  FIG. 5  shows a display state of the lower image display panel  16  when the rank “Major Jackpot” results from a JP game. As shown in the upper-right screen in the lower part of  FIG. 5 , as a payout image  164  corresponding to the rank “Major Jackpot”, a payout image  164   b  showing a tuna is displayed with a character image  162   b . The lower-left screen in the lower part of  FIG. 5  shows a display state of the lower image display panel  16  when the rank “Mini Jackpot” results from a JP game. As shown in the lower-left screen in the lower part of  FIG. 5 , as a payout image  164  corresponding to the rank “Mini Jackpot”, a payout image  164   c  showing a napoleon fish is displayed with a character image  162   b . The lower-right screen in the lower part of  FIG. 5  shows a display state of the lower image display panel  16  when a rank as a result of a JP game is “Lose”. As shown in the lower-left screen in the lower part of  FIG. 5 , as a payout image  164  corresponding to the rank “Lose”, a payout image  164   d  showing an angelfish is displayed with a character image  162   b . As shown in  FIG. 5 , an image of a fish in the payout image  164  is changed in accordance with the rank. It is noted that an embodiment of images displaying a result of a JP game is not limited to the above. 
     In addition to the above, the sizes of the payout images  164  are made different in accordance with timings to participate in a JP game, even if the rank is identical. For example, even if the same rank “Mini Jackpot” is achieved, payout amounts are made different in accordance with the order of achieving the rank. Specifically, even if the same rank “Mini Jackpot” is achieved, a player who achieved the rank first receives a higher payout amount than a player who achieved the rank second. Therefore, as illustrated in  FIG. 1 , the size of the payout image  164  indicating the rank is arranged to be small as compared to a case where a payout amount is higher even if the rank is the same. 
     In this way, a payout awarded as a result of a JP game is determined by (i) a rank determined according to a result of the JP game, (ii) a timing to run the JP game, and (iii) a game value accumulatively stored in the payout memory. Specifically, a player for whom a JP game is run earlier than for another player receives a higher payout, even if the rank of these players is the same. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the display, a player is motivated to continue a game thanks to decreased stress on him/her. 
     (Display States of Shared Display  203 ) 
     Referring to  FIG. 6 , the following specifically describes an example of display states of the shared display  203  in the operation process in accordance with the above-described gaming machine  1  and playing method. As illustrated in  FIG. 6 , players of respective gaming terminals  10  (gaming terminal  10   a  to gaming terminal  10   d ) can see that a JP game is displayed on the shared display  203 . 
     When the JP game starts, the shared display  203  displays pointer images  167  (pointer images  167   a  to  167   d ). These pointer images  167  indicate the respective gaming terminals  10 . That is to say, the pointer image  167   a  indicate the gaming terminal  10   a , the pointer image  167   b  indicate the gaming terminal  10   b , the pointer image  167   c  indicate the gaming terminal  10   c , and the pointer image  167   d  indicate the gaming terminal  10   d . In this example, the pointer image  167  specifically indicates the face part of the character image  162 . 
     The shared display  203  has a pointer display area  166 . As illustrated in  FIG. 6 , the pointer display area  166  is provided at the center of the shared display  203 . The pointer display area  166  is a display area where a pointer image  167  indicating each gaming terminal  10  is displayed. Further displayed in the pointer display area  166  is a line-shaped line image  165  which horizontally extends in the lower part in such a way as to traverse the pointer display area  166 . 
     The pointer images  167  are arranged in accordance with the order in which the gaming terminals  10  participate in a JP game. Specifically, the pointer images  167  are arranged from the bottom to the top, in accordance with the temporal order of participation. 
     The displayed pointer images  167  are, as illustrated in  FIG. 6 , scrolled downward over time. In other words, the pointer images  167  move toward the line image  165 , reach the line image  165 , and then pass over the line image  165 . 
     The notification of a result of a JP game is carried out when a pointer image  167  reaches the line image  165 . Specifically, the notification of a payout of a JP game is carried out in such a way that, when a pointer image  167  reaches the line image  165 , the lower image display panel  16  of the gaming terminal associated with that pointer image  167  displays a comment image  163  in the vicinity of the character image  162 , and then displays a payout image  164 . Along with the notification of the payout, the payout is awarded. 
     In this way character images  162  associated with the respective gaming terminals  10  are displayed on the shared display  203  viewable from the gaming terminals  10 , and this allows players to share a sense of participation. This provides a player with a new entertainment characteristic. 
     Although the present embodiment presupposes that JP game is a fishing game, JP game may be another type of game such as a hunting game. It is also noted that the pointer images  167  and the line image  165  are not necessarily displayed in the manner as above. It is also noted that the pointer images  167  are not necessarily arranged as above. It is also noted that the pointer images  167  do not necessarily move in the manner as above. For example, the pointer images  167  may move in the crosswise direction or upward. 
     (Symbols, Winning Combination, etc) 
     The base symbols  180  displayed in the matrix  156  on the lower image display panel  16  are arranged so that 22 symbols constitute a single symbol column as illustrated in  FIG. 7 . To each of the symbols constituting the columns is given one of code numbers  0  to  21 . Each of the symbol columns has a combination of symbols including “Angelfish”  182 , “Clownfish”  181 , “7”  185 , “Tuna”  183 , “Coelacanth”  184 , and “BONUS”  186 . As illustrated in  FIG. 3 , the base symbols  180  are arranged in the respective base symbol arrangement areas  150   a  of the symbol columns. 
     Three successive symbols in the symbol columns are displayed (arranged) in the upper stages  151   a  to  155   a , the middle stages  151   b  to  155   b , and the lower stages  151   c  to  155   c  of the display windows  151  to  155 , so that the symbols form a symbol matrix having five columns and three rows in the display windows  151  to  155 . When a BET button and a start button are sequentially pressed in this order to start a game, symbols constituting the symbol matrix start to scroll. This scrolling of the symbols stops (rearrangement) after a predetermined period from the beginning of the scrolling. 
     For each base symbol  180  a winning combination has been determined in advance. A winning combination is arranged such that a state advantageous for a player is achieved when at least a predetermined number of symbols are successively displayed on one of paylines L of the matrix  156 . For example, the advantageous states include: a state where coins corresponding to a winning combination are paid out, a state where the number of coins to be paid out is added to a credit, and a state where a bonus game is started. The payline L will be discussed later. 
     For example, when three or more symbols of “Clownfish”  181  are rearranged on the payline L, five coins are paid out for each BET or a credit corresponding to five coins is added. In short, game media (game values) are awarded. 
     In another case, for example, when three or more symbols of “BONUS” are rearranged on the payline L, a bonus is triggered and the gaming state shifts from a base game to a bonus game. When four or more “BONUS” symbols are stopped on the matrix  156 , 20 coins (game media) are paid out for each BET. 
     Here, a bonus game is a gaming state which provides a larger advantage than a base game. In this embodiment, the bonus game is a free game. The free game is a game allowing a player to play a game for a predetermined number of times without betting a coin. No particular limitation is put on the bonus game, as long as it is a gaming state advantageous to the player, that is, it is more advantageous than the base game. For example, the bonus game may include a state where more game media are obtainable than in the base game, a state where a game medium is obtainable with higher probability than in the base game, a state where a game medium is less consumed than in the base game, and the like. Specifically, a free game, a second game, a feature game, and the like may be mentioned as examples of the bonus game. 
     The lower image display panel  16  displays three activated paylines L as illustrated in  FIGS. 3 . The “payline L” is used for determining a winning combination of the base symbols  180 . That is, when the base symbols  180  are rearranged on and out of the payline L, a combination is determined for only the base symbols  180  rearranged on the payline. When the combination is recognized as a winning combination in consequence of the determination, an advantageous state of the player is established in accordance with the winning combination. That is to say, coins are paid out in accordance with the winning combination, the number of coins to be paid out is added to a credit, or a bonus game is started, for example. Note that, not limited to three, the number of paylines L maybe one, two, four, or more. When the number of paylines L is two or more, the number of paylines L activated may be determined according to a predetermined condition, such as the number of coins placed as a BET. In this case, the number of activated paylines L may be notified by a lamp or the like. 
     As illustrated in  FIG. 3 , the paylines L include a top line  161   a  traversing the upper stages  151   a ,  152   a ,  153   a ,  154   a , and  155   a , a central line  161   b  traversing the central stages  151   b ,  152   b ,  153   b ,  154   b , and  155   b , and a bottom line  161   c  traversing the lower stages  151   c ,  152   c ,  153   c ,  154   c , and  155   c . When three or more base symbols  180  are successively rearranged on at least one of the paylines  161   a  to  161   c , it is determined that a winning combination is met. For example, in the case of  FIG. 3 , a winning combination of “Clownfish” has been met because three symbols of “Clownfish”  181  are successively rearranged on the top line  161   a  of the display windows  151  to  153 . 
     The JP symbols  180  are “scatter symbols” which are such symbols which provide a JP chance to a player when a predetermined number or more (e.g. three) of them are displayed in the matrix  156 . For example, in the case of  FIG. 3 , the JP symbols  180 J are arranged on the upper stage  151   a  and the lower stage  151   c  of the display window  151 , the lower stage  153   c  of the display window  153 , and the central stage  154   b  of the display window  154 . Since four JP symbols  180 J are arranged in this case, a JP chance is awarded to a player. 
     In this way, a result of a base game is determined according to whether base symbols  180  are successively rearranged on a payline L, whereas a result of a chance game is determined according to whether there are a predetermined number or more of rearranged JP symbols  180 J. As such, a base game and a chance game are similar slot games but adopt different methods of determining a result. Therefore a player may be possible to easily grasp the results of any games. This may release the stress of the player. The method of how to determine results of a base game and a chance game is not limited to the above. Both of them may be obtained by the scatter symbol method or by the winning combination method. Alternatively, a result of a base game is determined by the scatter symbol method whereas a result of a chance game is determined by the winning combination method. 
     The lower image display panel  16  may further display a credit value indicator and a payout value indicator. The credit value indicator displays a total value (hereinafter also referred to as total credit value) which a gaming terminal  10  can pay out to a player. The payout value indicator displays the number of coins to be paid out, when a predetermined number or more of base symbols  180  are successively rearranged on a payline L. 
     (Mechanical Structure of Gaming Machine  1 ) 
     As illustrated in  FIG. 8 , the gaming machine  1  includes: gaming terminals  10  which run a base game independently from each other (the number of gaming terminals  10  is  4  in the present embodiment); a center control unit  200  connected to the gaming terminals  10 , which is in communication with the gaming terminals  10  and runs a JP game; a shared display  203  which displays thereon an effect image related to the JP game; a rail  271  which allows the shared display  203  to move to a position immediately above one of the gaming terminals  10 ; and a not-illustrated drive motor  270 . 
     Four gaming terminals  10  are laterally arranged in a parallel manner, with their terminal displays  101  (each including the lower image display panel  16  and the upper image display panel  33 ) facing forward. The rail  271  is arranged so as to cover the four gaming terminals  10 . The shared display  203  is arranged on the rail  271  and its screen faces in the same direction as the terminal displays  101 .

The lower image display panel  16  displays display windows  151  to  155  and a matrix  156  for arranging therein base symbols  180  and JP symbols  180 J. Further, the lower image display panel  16  displays as needed various types of information and effect images related to games. Displayed in the upper-right part of the lower image display panel  16  is a JP chance display area  160 . 
     This embodiment deals with a case where the lower image display panel  16  electrically displays base symbols  180  and JP symbols  180 J in such a way that a base symbol  180  overlaps a JP symbol  180 J, with the result that the symbols are arranged in five rows/three columns. However, the present invention is not limited to this. 
     Below the lower image display panel  16  provided are a control panel  20 , a coin insertion slot  21 , and a bill validator  22 . The control panel  20  has buttons  23  to  27 . These buttons  23  to  27  allow a player to input instructions related to a game played by the player. Through the coin insertion slot  21 , a coin is received in the cabinet  11 . 
     The control panel  20  includes: a spin button  23 , a change button  24 , a cashout button  25 , a 1-BET button  26 , and a maximum BET button  27 . The spin button  23  is for inputting an instruction to start symbol scrolling. The change button  24  is used to ask a staff person in the gaming facility for exchange of money. The cashout button  25  is for inputting an instruction to pay out coins corresponding to the total credit value into the coin tray  18 , via a coin payout opening  19 . 
     The 1-BET button  26  is used for betting one coin out of those corresponding to the total credit value. The maximum BET button  27  is used for betting, out of those corresponding to the total credit value, a maximum number of coins (e.g., fifty coins) which can be bet in one game. Note that the number of coins corresponding to 1 BET is not limited to the above. 
     The bill validator  22  validates whether bill is genuine or not and receives the genuine bill into the cabinet  11 . Note that the bill validator  22  is capable of reading a later-mentioned ticket  39  having a barcode. When the bill validator  22  reads the ticket  39 , it outputs to the main CPU  41  a read signal representing information having read from the barcode. 
     On the lower front surface of the main door  13 , that is, below the control panel  20 , a berry glass  34  is provided. On the belly glass  341  a character of a gaming terminal  10  or the like is drawn. On the front surface of top box  12  is provided an upper image display panel  33 .

     (Electrical Structure of Gaming Machine  1 ) 
       FIGS. 10 and 11  are block diagrams each illustrating an electrical structure of the entire gaming machine  1 . 
     (Electrical Structure of Gaming Terminal  10 ) 
       FIG. 10  is a block diagram illustrating an electrical structure of the gaming terminal  10 . As illustrated in  FIG. 10 , the cabinet  11  includes therein a control unit having at least one of the functions of a controller  100 . The control unit includes, as shown in  FIG. 10 , a motherboard  40 , a main body PCB (Printed Circuit Board)  60 , a gaming board  50 , a door PCB  80 , various switches, sensors, or the like. 
     The gaming board  50  is provided with a CPU (Central Processing Unit)  51 , a RON  55 , a boot ROM  52 , a card slot  53 S corresponding to a memory card  53 , and an IC socket  54 S corresponding to a GAL (Generic Array Logic)  54 . The CPU  51 , the ROM  55 , and the boot ROM  52  are connected to one another through an internal bus. 
     The memory card  53  stores therein a game program and a game system program. The game program contains a stop symbol determining program. The stop symbol determining program is a program for determining: base symbols  180  (code numbers corresponding to the symbols) to be stopped in the base symbol arrangement area  150   a ; and JP symbols  180 J (code numbers corresponding to the symbols) to be stopped in the JP symbol arrangement area  150   b . This stop symbol determining program contains sets of symbol weighting data respectively corresponding to various payout rates (e.g., 80%, 84%, 88%). Each set of the symbol weighting data indicates, for each of the display windows  151  to  155 , a code number of each symbol and at least one random numerical value allotted to the code number. The numerical value is a value within a predetermined range of 0 to 256 for example. 
     The payout rate is determined based on payout rate setting data output from the GAL  54 . Based on a set of the symbol weighting data corresponding to the payout rate determined, a symbol to be stopped is determined. 
     The memory card  53  stores therein various types of data for use in the game programs and the game system programs. For example, data listing combinations of a base symbol  180  to be displayed on the display windows  151  to  155  of  FIG. 3  and an associated range of random numerical values is stored in the form of a table. This data is transferred to the RAM  43  of the motherboard  40 , at the time of running a game program. 
     The card slot  53 S is structured so as to allow the memory card  53  to be attached/detached to/from the card slot  53 S. This card slot  53 S is connected to the motherboard  40  through an IDE bus. Thus, the type and content of a game run by a gaming terminal  10  can be modified by detaching the memory card  53  from the card slot  53 S, write a different game program and a different game system program into the memory card  53 , and inserting the memory card  53  back into the card slot  53 S. 
     Each of the game programs includes a program related to the progress of the game and/or a program for causing a transition to a bonus game. Each of the game programs Includes image data and audio data output during the game. 
     The GAL  54  has input and output ports. When the GAL  54  receives data via the input port, it outputs data corresponding to the input data from its output port. This data from the output port is the payout rate setting data described above. 
     IC socket  54 S is structured so as to allow the GAL  54  to be attached/detached to/from the IC socket  545  The IC socket  54 S is connected to the motherboard  40 , via a PCI bus. Thus, the payout rate setting data to be output from GAL  54  can be modified by: detaching the GAL  54  from the IC socket  54 S, overwriting the program stored in the GAL  54 , and attaching the GAL  54  back to the IC socket  54 S. 
     The CPU  51 , the RON  55  and the boot ROM  52  connected through an internal bus are connected to the motherboard  40  through the PCI bus. The PCI bus communicates signals between the motherboard  40  and the gaming board  50  and supplies power from the motherboard  40  to the gaming board  50 . The ROM  55  stores country identification information and an authentication program. The boot ROM  52  stores a preliminary authentication program and a program (boot code) for enabling the CPU  51  to run the preliminary authentication program. 
     The authentication program is a program (falsification check program) for authenticating the game program and the game system program. The authentication program is a program for confirming and verifying that the game program and the game system program are not falsified. In other words, the authentication program is described in accordance with a procedure for authenticating the game program and the game system program. The preliminary authentication program is a program for authenticating the authentication program. The preliminary authentication program is described in accordance with a procedure for verifying that the authentication program to be authenticated is not falsified. In short, the preliminary authentication program authenticates the authentication program. 
     The motherboard  40  is provided with a main CPU  41 , a ROM (Read Only Memory)  42 , a RAM (Random Access Memory)  43 , and a communication interface  44 . 
     The main CPU  41  has at least one of the functions of a controller  100  controlling the entire gaming machine  1 , and the main CPU  41  controls a gaming terminal  10 . In particular, the main CPU  41  controls the following operations: an operation of outputting a signal instructing variable-displaying of symbols  180  to the graphic board  68 , which is performed in response to pressing of the spin button  23  after betting of credit; an operation of determining symbols  180  to be stopped after the variable-displaying of symbols  180 ; and an operation of stopping the symbols  180  thus determined in the display window  151  to  155 . 
     In other words, the main CPU  41  serves as an arrangement controller which arranges symbols to form a new symbol matrix through scrolling of symbols displayed on the lower image display panel  16 . This main CPU  41  therefore determines symbols to be arranged in a symbol matrix by selecting symbols to be arranged from various kinds of symbols. Then, the main CPU  41  executes arrangement control to stop scrolling the symbols to present the symbols thus determined. 
     The ROM  42  stores a program such as BIOS (Basic Input/Output System) run by the main CPU  41 , and permanently-used data. When the BIOS is run by the main CPU  41 , each of peripheral devices is initialized and the game program and the game system program stored in the memory card  53  are read out through the gaming board  50 . The RAM  43  stores data or a program used for the main CPU  41  to perform a process. 
     In addition, the ROM  42  stores a gaming terminal ID unique to each gaming terminal  10 . When various signals are transmitted to the center control unit  200 , the center control unit  200  can identify the senders of these signals, because gaming terminal ID information is added to the header of the like of each signal. A gaming terminal ID is, for example, an IP (Internet Protocol) address of each gaming terminal  10 . 
     In addition to the above, the RAM  43  stores a JP timing which is based on a JP timing signal transmitted from the center control unit  200 . This JP timing is information regarding timing to start a JP game, and is determined after a JP game finishes in the center control unit  200 . The JP timing signal is a signal including information generated based on the JP timing, and this signal is transmitted from the center control unit  200 . 
     In the RAM  43 , furthermore, image data is stored that is used for displaying a character image  162 , a comment image  163 , a payout image  164 , a line image  165 , a pointer image  167  or the like on the lower image display panel  16 . 
     The communication interface  44  is provided to communicate with a host computer and the like equipped in the gaming facility, through a communication line. The communication interface  44  is also used for performing communication with the center control unit  200  over a communication line. Further, a main body PCB (Printed Circuit Board)  60  and a door PCB  80  are connected to the motherboard  40 , through USB (Universal Serial Bus). Further, the motherboard  40  is connected to a power unit  45 . The power unit  45  supplies power to the motherboard  40  to boot the main CPU  41  thereof. Meanwhile, the power unit  45  supplies power to the gaming board  50  through the PCI bus to boot the CPU  51 . 
     The main body PCB  60  and door PCB  80  are connected to various devices or units which generate signals to be input to the main CPU  41 , and various devices or units whose operations are controlled by signals from the main CPU  41 . Based on a signal input to the main CPU  41 , the main CPU  41  runs the game program and the game system program stored in the RAM  43 , to perform an arithmetic process. Then, the CPU  41  stores the result of the arithmetic process in the RAM  43 , or transmits a control signal to the various devices and units to control them based on the result. 
     The main body PCB  60  is connected with a lamp  30 , a hopper  66 , a coin sensor  67 , a graphic board  68 , the speaker  29 , a bill validator  22 , a ticket printer  35 , a card reader  36 , a key switch  38 S, and a data displayer  37 . 
     The lamp  30  is turned on/off on the basis of a control signal from the main CPU  41 . 
     The hopper  66  is mounted in the cabinet  11  and pays out a predetermined number of coins from a coin outlet  19  to the coin tray  18 , based on a control signal from the main CPU  41 . The coin sensor  67  is provided inside the coin outlet  19 , and outputs a signal to be input to the main CPU  41  upon sensing that a predetermined number of coins have been delivered from the coin outlet  19 . 
     The graphic board  68  controls image displaying of upper image display panel  33  and the lower image display panel  16 , based on a control signal from the main CPU  41 . Further, the graphic board  68  is provided with a VDP (Video Display Processor) for generating image data on the basis of a control signal from the main CPU  41 , a video RAM for temporarily storing the image data generated by the VDP, or the like. Note that image data used at the time of generating the image data by the VOP is in a game program which is read out from the memory card  53  and stored in the RAM  43 . 
     The bill validator  22  reads an image on the bill and takes only those recognized as to be genuine into the cabinet  11 . When taking in a genuine bill, the bill validator  22  outputs an input signal indicating the value of the bill to the main CPU  41 . The main CPU  41  stores into the RAM  43  a credit-value corresponding to the value of the bill indicated by the signal. 
     The ticket printer  35  prints a barcode on to a ticket to issue a ticket  39  having the barcode. The barcode contains encoded data such as credit-value stored in the RAM  43 , date and time, identification number of the gaming terminal  10 , or the like, based on a control signal from the main CPU  41 . 
     The card reader  36  reads out data from the smart card and transmits the data to the main CPU  41 . Further, the card reader  36  writes data into the smart card based on the control signal output from the main CPU  41 . The key switch  38 S is mounted to the keypad  38 , and outputs a signal to the main CPU  41  in response to an operation of the keypad  38  by the player. The data displayer  37  displays, based on a control signal from the main CPU  41 , the data read by the card reader  36  or the data input by the player through the keypad  38 . 
     The door PCB  80  is connected to a control panel  20 , a reverter  21 S, a coin counter  21 C, and a cold cathode tube  81 . The control panel  20  is provided with: a spin switch  23 S associated with the spin button  23 ; a change switch  24 S associated with the change button  24 ; a cashout switch  258  associated with the cashout button  25 ; a 1-BET button switch  26 S associated with the 1-BET button  26 ; and a maximum BET switch  27 S associated with the maximum BET button  27 . Each of the switches  23 S to  27 S outputs an input signal to the main CPU  41 , when a player presses the associated button. 
     The coin counter  21 C is provided within the coin insertion slot  21 , and identifies whether the coin inserted into the coin insertion slot  12  by the player is genuine. A coin except the genuine coin is discharged from the coin outlet  19 . In addition, the coin counter  21 C outputs an input signal to the main CPU  41  upon detection of a genuine coin. 
     The reverter  21 S is operated on the basis of the control signal output from the main CPU  41  and distributes a coin, which is recognized as a genuine coin by the coin counter  21 C, to a not-illustrated cash box or hopper  66  mounted in the gaming terminal  10 . In other words, when the hopper  66  is full of the coins, the genuine coin is distributed into the cash box by the reverter  21 S. On the other hand, when the hopper  66  is not yet full with the coins, the genuine coin is distributed into the hopper  66 . The cold cathode tube  81  functions as a backlight mounted to rear sides of the lower image display panel  16  and the upper image display panel  33 . This cold cathode tube  81  turns on according to a control signal from the main CPU  41 . 
     (Electrical Structure of Center Control Unit  200 ) 
       FIG. 11  is a block diagram showing the electrical structure of the center control unit  200 . Disposed in the center control unit  200  is a control unit. As illustrated in  FIG. 11 , the control unit includes a motherboard  240  a gaming board  250 , an actuator, or the like. 
     The gaming board  250  is provided with a CPU  251 , a ROM  255 , a boot ROM  252 , a card slot  253 S corresponding to a memory card  253 , and an IC socket  254 S corresponding to a GAL  254 . The CPU  251 , the ROM  255 , and the boot ROM  252  are connected to one another through an internal bus. 
     The memory card  253  stores therein a game program, a game system program, and various types of data for use in the game program and the game system program. Specifically, the memory card  253  stores data such as a program for managing each gaming terminal  10  and a program for running a JP game. Such programs and data are transmitted to the motherboard  240  at the time of boot of the center control unit  200 , running of a program, and so forth. 
     Each of the game program includes a program related to the progress of the JP game. Each of the game programs also includes image data and audio data output during the JP game. 
     The gaming board  250  has, as illustrated in  FIG. 11 , a similar structure to the gaming board  50  of the gaming terminal  10 , and hence a further explanation of the structure is not given. 
     The motherboard  240  includes a main CPU  241 , a ROM  242 , a RAM  243 , and a communication interface  244 . 
     The main CPU  41  has at least one of the functions of a terminal controller  100  controlling the entire gaming machine  1 , and the main CPU  41  controls a center control unit  200 . The ROM  242  stores a program run by the main CPU  241 , and permanently-used data. The RAM  243  stores data or a program used for the main CPU  241  to perform a process. The communication interface  244  communicates with the gaming terminals  10  through a communication line. 
     The ROM  242  also stores a program which extracts random numerical values. The random numerical value extraction program is run by the main CPU  41 . In the present embodiment, random numerical value sampling is carried out by a program. The present invention however is not limited to this arrangement. For example, the present invention may be structured to include a random number generating circuit which generates a predetermined range of random numerical values and a sampling circuit which samples a random numerical value from the values generated by the random number generating circuit. 
     In addition, although not being illustrated, the RON  242  stores data indicating a relation between ranks and random numerical ranges, in the form of a table. This table is referred to when a payout is awarded as a result of a JP game. More specifically, after it is determined that a sampled random numerical value is included in any one of random numerical ranges of the table, a rank corresponding to that range is determined as a rank corresponding to the result of the JP game. 
     In addition, the RAM  243  stores progressive values accumulatively supplied from each gaming terminal  10 . The progressive values are used as the source of payout when jackpot is met in a JP game. The RAM  243  also stores the timing of the next JP game, which is determined when the current JP game finishes. 
     The center control unit  200  includes, as main actuators, a graphic board  268 , a drive motor  270 , and a clock IC  280 . 
     The graphic board  268  has the same structure as that of the graphic board  68 , except in that the graphic board  268  controls image displaying of the shared display  203  based on a control signal from the main CPU  241 . 
     The drive motor  270  is a stepping motor and is connected to a not-shown drive wheel. The drive motor  270  is driven by a control signal from the main CPU  241 , and rotates the drive wheel to move the shared display  203 . 
     The clock IC  280  functions as the timer  228  of the present invention. The clock IC  280  is structured to output data of current time in response to a request from the main CPU  241 . For example, the clock IC  28  maybe constituted by an oscillating circuit, a frequency divider, or the like, or may be structured to include software or the like. 
     The center control unit  200  further includes a power unit  245 . The power unit  245  serves as a power source for supplying power to the motherboard  240 . 
     (JP Chance Data Table) 
     Referring to  FIG. 12 , a JP chance data table is described. The JP chance data table is stored in the RAM  243  of the center control unit  200 . The JP chance data table has a JP chance award timing list and a JP chance number list. The JP chance number list has gaming terminal ID fields (fields A to D). The JP chance award timing list stores time at which a JP chance is awarded to a player in a chance game at each gaming terminal  10 . The JP chance number list stores for each gaming terminal ID the number of obtained JP chances. In other words, the JP chance data table is arranged such that the number of JP chances that a gaming terminal  10  has obtained is stored in association with the time at which the JP chance is obtained and the gaming terminal ID of that gaming terminal  10 . 
     Specifically, when a player at the gaming terminal  10  with the gaming terminal ID “A” is awarded a JP chance in a chance game, the gaming terminal  10  transmits a JP chance signal to the center control unit  200 . This JP chance signal includes gaming terminal ID information indicating “A” and JP chance number information indicating the number of awarded JP chances. Receiving the JP chance signal, the center control unit  200  increases, in the JP chance data table, the JP chance number associated with the gaming terminal ID along with the time at which the JP chance was obtained. 
     In a JP game run by the center control unit  200 , when the gaming terminals  10  participate in the JP game, the JP chance number corresponding to each of the participating gaming terminals  10  is decremented in the JP chance data table, each time whether jackpot is met or not is determined. 
     Now, the following will specifically describe the data operation of the JP chance data table by the center control unit  200 . When a JP game is run, the JP chance award timing list is searched for a cell storing the earliest time. For the gaming terminal  10  having obtained the number of JP chances corresponding to the time thus found, there is determined whether or not a jackpot is met. The number of JP chances is reduced by 1 each time the determination of whether to meet a jackpot is performed. The determination of whether to meet a jackpot is repeated until the number of JP chances becomes 0. When the aforesaid number of JP chances becomes 0, the JP chance award timing list is searched for the second earliest time, and the data operation above is repeated. 
     The order in which the gaming terminals  10  participate in the JP game is determined based on the observation that in which gaming terminal ID field of the JP chance number list in the JP chance data table the JP chance number is stored. The order of participation of the gaming terminals  10  in the JP game is temporarily stored in the RAM  243  and is referred to when the pointer images  167  are arranged. 
     (JP Result Data Table) 
     Referring to  FIG. 13 , a JP result data table is described. The JP result data table is stored in the RAM  243  of the center control unit  200 . The JP result data table has a rank list and a payout amount list. The rank list stores a rank achieved as a result of a JP game. The payout amount list stores a payout amount awarded in an achieved rank. 
     The JP result data table is updated when a result of a JP game is determined. Also, the JP result data table is referred to when, in a JP game, a rank is determined and a payout amount is determined. Specifically, whether or not a JP game result whose rank is identical with a rank determined in a JP game is stored in the table. If such a rank exists, a payout amount is determined to be lower than the payout amount stored in the JP result data table. When the JP game is finished, the data is initialized. 
     The JP result table is not necessarily structured as above. For example, the table may be updated in such a way that a minimum payout amount of each rank is overwritten. This improves the speed of reference. 
     (Operation of Gaming Machine  1 : Boot Process) 
     The following describes a boot process routine which takes place in the gaming machine  1 . Upon powering on the gaming machine  1 , the motherboard  240  and gaming board  250  in the center control unit  200 , and the motherboard  40  and the gaming board  50  in the gaming terminal  10  execute the boot process routine illustrated in  FIG. 14 . The memory cards  53  and  263  are assumed to be inserted into the card slots  53 S and  263 S of the gaming boards  50  and  250 , respectively. Further, the GALs  54  and  254  are assumed to be attached to the IC sockets  54 S and  254 S, respectively. 
     First, turning on the power switch of (powering on) the power units  45  and  245  boots the motherboards  40  and  240  and the gaming boards  50  and  250 . Booting the motherboards  40  and  240  and the gaming boards  50  and  250  starts separate processes in parallel. Specifically, in the gaming boards  50  and  250 ,the CPUs  51  and  251  read out preliminary authentication programs stored in the boot ROMs  52  and  252 , respectively. Then, preliminary authentication is performed according to the read out programs so as to confirm and authenticate that no modification is made to authentication programs, before reading them in the motherboards  40  and  240 , respectively (SI). Meanwhile, the main CPUs  41  and  241  of the motherboards  40  and  240  run BIOS stored in the ROMs  42  and  242  to load into the RAMs  43  and  243  compressed data built in the BIOS, respectively (S 2 ). Then, the main CPUs  41  and  241  run a procedure of the BIOS according to the data loaded into the RAMs  43  and  243  so as to diagnose and initialize various peripheral devices (S 3 ). 
     The main CPUs  41  and  241 , which are respectively connected to the ROMs  55  and  255  of the gaming boards  50  and  250  via PCI buses, read out authentication programs stored in the ROMs  55  and  255  and store them in the RAMs  43  and  243  (S 4 ). During this step, the main CPUs  41  and  241  each derives a checksum through ADDSUM method (a standard check function) which is adopted in a standard BIOS, and store the authentication programs into RAMs  43  and  243  while confirming if the operation of storing is carried out without an error. 
     Next, the main CPUs  41  and  241  each checks what connects to the IDE bus. Then, the main CPUs  41  and  241  access, via the IDE buses, to the memory cards  53  and  253  inserted into the card slots  53 S and  253 S, and read out game programs and game system programs from the memory cards  53  and  253 , respectively. In this case, the CPUs  41  and  241  each reads out four bytes of data constituting the game program and the game system program at one time. Next, the CPUs  41  and  241  authenticate the game program and the game system program read out to confirm and prove that these programs are not modified, in accordance with the authentication programs stored in the RAMs  43  and  243  (S 5 ). 
     When the authentication properly ends, the main CPUs  41  and  241  write and store the authenticated game programs and game system programs in RAMs  43  and  243  (S 6 ). 
     Next, the main CPUs  41  and  241  access, via the PCI buses, to the GALs  54  and  254  attached to the IC sockets  54 S and  2548 , and read out payout rate setting data from the GALs  54  and  254 , respectively. The payout rate setting data read out is then written and stored in the RAMs  43  and  243  (S 7 ). 
     Next, the main CPUs  41  and  241  read out, via the PCI buses, country identification information stored in the ROMs  55  and  255  of the gaming boards  50  and  255 , respectively. The country identification information read out is then stored in the RAMs  43  and  243  (S 8 ). 
     After this, the main CPUs  41  and  241  each performs an initial process of  FIG. 15 . 
     (Operation of Gaming Machine  1 : Initial Process) 
     The following describes an initial process which takes place in the gaming machine  1 . After the execution of the boot process shown in  FIG. 14 , the center control unit  200  reads out from the RAM  243  and executes a center side initial setting routine shown in  FIG. 15 . Meanwhile, after the execution of the boot process shown in  FIG. 14 , the gaming terminal  10  reads out from the RAM  43  a terminal side initial setting routine illustrated in  FIG. 15  and executes the routine. The center side and terminal side initial setting routines are executed in parallel. 
     First, the main CPU  41  of the gaming terminal  10  checks operations of a work memory such as RAM  43  (A 1 ). Then, the main CPU  41  determines if all the check results are normal (A 2 ). If the main CPU  41  determines that the check results contain an error (A 2 : NO), an error signal is supplied to the center control unit  200  (A 3 ). Further, the error is notified in the form of illuminating the lamp  30  or the like (A 4 ), and then the routine is ended. 
     On the other hand, if the main CPU  41  determines that the check results are all normal (A 2 :YES), the main CPU  41  checks operations of various sensors (A 5 ). Then, the main CPU  41  determines if all the check results are normal (A 6 ). If the main CPU  41  determines the check results contain an error (A 6 : NO), the main CPU  41  executes A 3 . 
     On the other hand in A 6 , if the main CPU  41  determines that the check results are all normal (A 6 : YES), the main CPU  41  checks operations of various drive mechanisms (A 7 ). Then, the main CPU  41  determines if all the check results are normal (A 8 ). If the main CPU  41  determines the check results contain an error (A 8 : NO), the main CPU  241  executes A 3 . 
     On the other hand in A 8 , if the main CPU  41  determines that the check results are all normal (A 8 : YES), the main CPU  41  checks operations of various illuminations (A 9 ). Then, the main CPU  41  determines if all the check results are normal (A 10 ). If the main CPU  41  determines the check results contain an error (A 10 : NO), the main CPU  41  executes A 3 . 
     After the checking operations through the steps A 1  to A 10  for checking operations of various functions, if the main CPU  41  determines that the check results are all normal (A 10 : YES), the main CPU  41  outputs an initial setting signal to the center control unit  200  (A 11 ). Thereafter the process waits for the supply of an initial setting signal from the center control unit  200  (A 12 , A 13 : NO). 
     Then the main CPU  241  of the center control unit  200  receives a signal from each gaming terminal  10  (B 1 ). Then, the main CPU  241  determines whether a signal received is an error signal (B 2 ). If the main CPU  241  determines that the signal is an error signal (B 2 : YES), the main CPU  241  outputs the error signal to a server of a not-illustrated host computer or the like (B 3 ) to report the error (B 4 ), and ends the routine. 
     On the other hand in B 2 , if the main CPU  241  determines that the signal is not an error signal (B 2 :NO), the main CPU  241  determines whether a predetermined time (check time) has elapsed from the time of powering on (B 5 ). If the main CPU  241  determines that the check time has elapsed (B 5 : YES), B 3  is executed. On the other hand, if the main CPU  241  determines that the check time has not yet elapsed (B 5 :NO), it is determined whether an initial setting signal is received from each of the gaming terminals  10  (B 6 ). If the main CPU  241  determines that an initial setting signal from any one of the gaming terminals  10  is not received (B 6 : NO), the process returns to B 1 . 
     On the other hand, if the main CPU  241  determines that initial setting signals from all the gaming terminals  10  are received (B 6 : YES), the main CPU  241  checks operations of work memory such as the RAM  243  (B 7 ). Then, the main CPU  241  determines whether all the check results are normal (B 8 ). If the main CPU  241  determines the check results contain an error (B 8 : NO), the main CPU  241  executes B 3 . 
     On the other hand, if the main CPU  241  determines that the check results are all normal (B 8 :YES), the main CPU  241  checks operations of various sensors (B 9 ). Then, the main CPU  241  determines whether all the check results are normal (B 10 ). If the main CPU  241  determines the check results contain an error (B 10 : NO), the main CPU  241  executes B 3 . 
     On the other hand in B 10 , if the main CPU  241  determines that the check results are all normal (B 10 :YES), the main CPU  241  checks operations of various driving mechanisms (B 11 ). Then, the main CPU  241  determines whether all the check results are normal (P 12 ). If the main CPU  241  determines the check results contain an error (B 12 : NO), the main CPU  241  executes B 3 . 
     On the other hand in B 12 , if the main CPU  241  determines that the check results are all normal (B 12 : YES), the main CPU  241  checks operations of various illuminations (B 13 ). Then, the main CPU  241  determines whether all the check results are normal (B 14 ). If the main CPU  241  determines the check results contain an error (R 14 : NO), the main CPU  241  executes B 3 . 
     After the checking operations through the steps B 7  to B 14 , if the main CPU  241  determines in B 14  that all the check results are normal (B 14 : YES), the main CPU  241  outputs an initial setting signal to all the gaming terminals  10  (B 15 ), and causes the shared display  203  to display a demo-screen (B 16 ). Then, the main CPU  241  ends the routine. 
     In A 12 , the main CPU  41  of each of the gaming terminals  10  determines that an initial setting signal is received from the center control unit  200  (A 13 : YES), and causes the terminal display  101  to display a demo-screen (A 14 ). The main CPU  41  then ends the routine. 
     (Operation of Gaming Terminal  10 : Game Running Process Routine) 
     After the terminal side initial setting routine of  FIG. 15 , the main CPU  41  of the gaming terminal  10  performs a game running process routine of  FIG. 16 . Through this game running process routine, a game is run. 
     As illustrated in  FIG. 16 , in the game running process routine, whether or not a JP game start signal is received from the center control unit  200  is determined (C 1 ). In C 1 , if it is determined that no JP game start signal is received (C 1 :NO), whether a coin is bet or not is determined (C 2 ). In this step, it is determined whether a signal from the 1-BET button switch  26 S entered by pressing of the 1-BET button  26  is received. Meanwhile, it is determined whether a signal from the maximum BET switch  27 S entered by pressing of the maximum BET button  27  is received. If no coin is BET (C 2 : NO), C 2  is repeated until a coin is bet. 
     On the other hand, if a coin is bet (C 2 : YES), the credit-value stored in the RAM  43  is reduced according to the number of coins bet (C 3 ). When the number of coins bet surpasses the credit value stored in the RAM  43 , the process goes to a later-detailed step C 4  without the reduction of the credit-value. When the number of coins bet exceeds the maximum number of coins bettable in one game (50 pieces in this embodiment), the process goes to a later-detailed step C 4  without the reduction of the credit-value. 
     Then, it is determined whether a spin button  23  is pressed or not (C 4 ). If the spin button  23  is not pressed (C 4 : NO), the process returns to C 2 . Here, if the spin button  23 is not pressed (for example, the spin button  23  is not pressed but a command to end the game is input), the reduction of the credit value in C 3  is canceled. 
     On the other hand, when the spin button  23  is pressed (C 4 : YES), a progressive transmission process is executed (C 5 ). In other words, a progressive signal indicating a part of the betted progressive value is transmitted to the center control unit  200 . 
     Next executed is a base symbol determining process (C 6 ). That is, the stop symbol determining program stored in the RAM  43  is run to determine base symbols  180  to be stopped in the matrix  156 . This determines a combination of base symbols to be stopped in the matrix  156 . 
     Next executed is a JP symbol determining process (C 7 ). That is, the stop symbol determining program stored in the RAM  43  is run to determine JP symbols  180 J to be stopped in the matrix  156 . Through this step is determined a combination of JP symbols to be stopped in the matrix  156 . 
     Then, the scrolling process is executed to scroll base symbols  180  and JP symbols  180 J at the same time, on the terminal display  101  (C 8 ). The scrolling process is a process in which the base symbols  180  and the JP symbols  180 J respectively determined in C 6  and C 7  are stopped (rearranged) in the matrix  156  after scrolling of symbols  180  and JP symbols  180 J in an upward/downward direction. 
     Then whether to award a JP chance is determined by determining whether a predetermined number or more of JP symbols  180 J are rearranged on the matrix  156  (C 9 ). If it is determined that no JP chance is awarded (C 9 :NO), there is determined whether a payout is awarded as a result of the base game by determining whether a winning combination is achieved by the base symbols  180  rearranged on the matrix  156  (C 12 ). 
     In the meanwhile, if it is determined in C 9  that a JP chance is awarded (C 9 :YES), a JP chance signal including the number of JP chances and the gaming terminal ID of the gaming terminal  10  is transmitted to the center control unit  200  (C 10 ). After C 10 , the number of JP chances is accumulatively stored in the RAM  43  (C 11 ). In this step, the accumulated total number of the JP chances is displayed in the JP chance display area  160  of the lower image display panel  16 . 
     Subsequently, if it has been determined in C 12  that there is payout as a result of the base game (C 12 :YES), an amount of payout is determined based on the rearranged base symbols  180  (C 13 ). After the payout is determined, a pay out process is executed (C 14 ). On the other hand in C 12 , if it is determined that there is no payout as a result of the base game (C 12 : NO), this routine is ended. 
     On the other hand, if in C 1  a JP game start signal has been received from the center control unit  200  (C 1 :YES), an effect image regarding the JP game is displayed on the lower image display panel  16  (C 15 ). Specifically, the character image  162  shown in the lower part of  FIG. 4  is displayed. 
     Then it is determined whether a gaming terminal determine signal is received from the center control unit  200  (C 155 ). The gaming terminal determine signal notifies a gaming terminal  10  of its turn to receive the determination of whether a jackpot is met in a JP game. If no gaming terminal determine signal has been received (C 155 : NO), the process of the step C 155  is repeated. When the gaming terminal determine signal has been received (C 155 :YES), a comment image  163  is displayed (C 156 ). Specifically, the comment image  163  shown on the gaming terminal  10   b  in the lower part of  FIG. 4  is displayed in the vicinity of the character image  162 . 
     When a JP game is started in this way, a player is on standby while a character image  162  is displayed, and he/she recognizes that his/her turn in a JP game has come when a comment image  163  is displayed in the vicinity of the character image  162 . 
     After an effect image regarding the JP game is displayed on the lower image display panel  16  in C 156 , there is determined whether a JP game payout signal is received from the center control unit  200  (C 16 ). If it is determined that no JP game payout signal is received (C 16 :NO), there is determined whether a JP game end signal is received from the center control unit  200  (C 18 ). 
     On the other hand, if it is determined that a JP game payout signal is received from the center control unit  200  in C 16  (C 16 :YES), a JP payout process is executed based on the JP game payout signal (C 17 ). Specifically, the JP payout process is carried out in such a way that, as shown in the lower part of  FIG. 5 , a character image  162  and a payout image  164  are displayed and a payout is awarded. C 18  is executed thereafter. 
     If it is determined that no JP game end signal is received (C 18 :NO), a JP game end signal is waited (C 18 ). 
     On the other hand, if it is determined in C 18  that a JP game end signal is received from the center control unit  200  (C 18 :YES), the number of JP chances stored in the RAM  43  is set at an initial value (C 19 ). In this step, the number of JP chances displayed on the JP chance display area  160  of the lower image display panel  16  is also set at the initial value. This routine ends thereafter. 
     (Operation of Center Control Unit  200 : Progressive Add Process Routine) 
       FIG. 17  shows a progressive add process routine in the center control unit  200 . When the progressive add process routine is executed, the main CPU  241  of the center control unit  200  determines whether a progressive signal is received from a gaming terminal  10  (D 1 ). If the center control unit  200  determines that no progressive signal is received (D 1 :NO), the center control unit  200  waits for a progressive signal (D 1 ). 
     On the other hand, if the center control unit  200  determines in D 1  that a progressive signal is received from a gaming terminal  10  (D 1 :YES), the center control unit  200  accumulatively stores a progressive value indicated by the progressive signal in the RAM  243  (D 2 ). This routine ends thereafter. 
     (Operation of Center Control Unit  200 : JP Chance Add Process routine) 
       FIG. 18  shows a JP chance add process routine in the center control unit  200 . When the JP chance add process routine is executed, the main CPU  241  of the center control unit  200  determines whether a JP chance signal is received from a gaming terminal  10  (E 1 ). If the center control unit  200  determines that no JP chance signal is received (E 1 : NO), the center control unit  200  waits for the JP chance signal (E 1 ). 
     On the other hand, if it is determined in E 1  that a JP chance signal has been received from a gaming terminal  10  (E 1 :YES), the gaming terminal ID of the gaming terminal  10  which has transmitted the signal is specified with reference to the JP chance signal (E 2 ) Then a time measuring process is carried out. Specifically, the clock IC  280  outputs current time to the main CPU  241 , in response to a request from the main CPU  241 . Then, the “gaming terminal ID” specified in E 2 , the “current time” specified in E 3 , and the “number of JP chances” which is based on the JP chance signal are associated with one another, and the associated sets of data are stored and updated in the JP chance data table of the RAM  243  (E 4 ). This routine ends thereafter. 
     (Operation of Center Control Unit  200 : JP Game Running Process Routine) 
       FIG. 19  shows a JP game running process routine executed by the main CPU  241  of the center control unit  200 . When the JP game running process routine is executed, the center control unit  200  determines whether a JP game starting time has come (F 1 ). If the center control unit  200  determines the JP game starting time has not come (F 1 :NO) the JP game starting time is waited (F 1 ). 
     On the other hand in F 1 , if the center control unit  200  determines the JP game starting time has come (F 1 :YES), the center control unit  200  determines if there is a gaming terminal  10  to participate in the JP game, by referring to the JP chance data table stored in RAM  243  (F 2 ). If it is determined that no gaming terminal  10  participates (F 2 :NO), the routine is ended. 
     On the other hand in F 2 , if there is a gaming terminal  10  to participate in the JP game (F 2 :YES), the center control unit  200  specifies the gaming terminal ID of that gaming terminal  10  (F 3 ). Specifically, the JP chance data table of the RAM  243  is searched for so that whether the number of JP chances is stored in each gaming terminal ID field of the JP chance number list is checked, with the result that a gaming terminal ID for which the number of JP chances has been stored is specified. Thereafter, a JP game start signal is transmitted to the gaming terminal  10  corresponding to the gaming terminal ID specified in F 4  (F 4 ). Then the order in which the gaming terminals  10  participate in the JP game is determined based on the JP chance data table in the RAM  243  (F 45 ). The order of participation of the gaming terminals  10  in the JP game is determined to correspond to the temporal order of obtaining JP chances. This order of participation is stored in the RAM  243 . Thereafter the JP game is started (F 5 ). Specifically, as illustrated in the upper part of  FIG. 6 , the pointer images  167  are arranged on the shared display in accordance with the order of participation determined in F 45 , and then the pointer images  167  are scrolled on the shared display. 
     As a result of this the pointer image  167  corresponding to the gaming terminal  10  at which the player is playing the game is displayed on the shared display  203 , and hence the player can recognize that he/she is participating in the JP game and can enjoy a new entertainment characteristic of sharing a sense of participation with other players. 
     When the JP game starts in F 5 , selected is a gaming terminal  10  to be subjected to a process of determining whether or not a jackpot is awarded. (F 6 ). Specifically, as discussed above, the order of gaming terminals  10  to be selected is determined with reference to the temporal order of awarding JP chances in the JP chance data table shown in  FIG. 12 . After the selection a gaming terminal determine signal is transmitted to the gaming terminal  10  thus selected. At the same time, the graphic board  268  is controlled so that the pointer image  167  indicating the thus determined gaming terminal  10  reaches the line image  165  on the shared display  203 . 
     Then, a process of determining whether or not a jackpot is awarded is performed with respect to a gaming terminal  10  with the gaming terminal ID determined in F 7  (F 7 ). If it is determined that a jackpot is not made (F 7 :NO), the number of JP chances obtained by the gaming terminal  10  with the determined gaming terminal ID, which number is stored in the RAM  243 , is reduced by “1” (F 11 ). 
     On the other hand, if in F 7  it is determined that a jackpot is met (F 7 :YES), a JP game payout determining process is executed (F 8 ) so that an amount of the payout is determined. This JP game payout determining process will be described later with reference to  FIG. 20 . After the process of F 8 , a JP game payout signal is transmitted to the gaming terminal  10  having the thus determined gaming terminal ID (F 9 ). It is noted that the JP game payout signal includes the determined number of payout of the JP game. 
     Next, a progressive value corresponding to the number of payout of the JP game determined in FE is subtracted from the accumulated progressive value in the RAM  243  (F 10 ). After F 10  is played F 11 . 
     After F 11 , there is determined whether JP chances of all the gaming terminals  10  stored in the RAM  243  are consumed (F 12 ). If it is determined that there is a JP chance yet to be consumed (F 12 : NO), a gaming terminal  10 , for which whether jackpot is awarded is to be determined, is determined again (F 6 ). 
     On the other hand, if it is determined in F 12  that all JP chances are consumed (F 12 :YES), a JP game end signal is transmitted to the gaming terminal  10  to which the JP game start signal have been transmitted (F 13 ). Thereafter the JP result data table is initialized (F 14 ), and the routine is finished. 
     Now, referring to  FIG. 20 , the following describes a JP game payout determining process routine executed by the main CPU  241  of the center control unit  200 . First, the main CPU  241  determines a rank (G 1 ). Then a progressive value to be stored in the RAM  243  is obtained (G 2 ). Based on the obtained progressive value, a payout amount whose ratio corresponds to the rank is figured out (G 3 ). 
     Thereafter the JP result data table is checked whether a payout amount whose rank is identical with the rank determined in the step G 1  has been stored (G 4 ). Whether a payout in the same rank is stored is determined as a result of the checking (G 5 ). If a payout in the same rank has been stored in the JP result data table (G 5 :YES), the calculated payout amount is compared with the stored payout amount and there is determined whether the stored payout amount is lower than the calculated payout amount (G 6 ). If it is determined that the stored payout amount is lower than the calculated payout amount (G 6 :NO), a process of reducing the payout amount thus referred to is executed (G 7 ). Specifically, the payout amount thus referred to is multiplied by 0.95 (G 8 ). 
     A payout amount determining process is executed if the process of the step G 8  has been finished, if there is no payout in the same rank in the step G 5 , or the payout amount thus referred to is higher than the payout amount calculated in the step G 6  (G 8 ). Specifically, when the process of the step G 7  has been executed, the reduced payout amount is determined as a payout amount of the JP game. In other cases, the payout amount calculated from the progressive value is determined as a payout amount of the JP game. 
     Then a notification process is executed (G 9 ). Specifically, as illustrated in  FIG. 5 , a rank image  168  is displayed in accordance with the rank, a payout amount image  169  is displayed in accordance with the payout amount, and a character image  162  is displayed in accordance with the gaming terminal ID. 
     Further displayed is a payout image  164  corresponding to the rank. That is to say, displayed is a payout image  164  having the size corresponding to the number of cases in the same rank stored in the rank list of the JP result table. Specifically, the more the number of cases in the same rank as the rank corresponding to the payout image  164  is, the smaller the size of the displayed payout image  164  is. 
     In this way, in the gaming machine  1  of the present embodiment, concurrently run are a base game offering a chance of winning a payout according to a predetermined combination and a chance game offering a chance of obtaining a JP chance which qualifies a player to join a JP game offering a chance of winning a higher payout than the base game. A payout is determined according to a result of the base game and awarded. In accordance with a result of the chance game, there is determined whether a JP chance is awarded. When a JP chance is awarded, the number of awarded JP chances is stored in the RAM  243  in association with the time of awarding the JP chance specified by the clock IC  280 . A timing to run a JP game is determined in accordance with the timing to award the JP chance. A pointer image  167  based on the timing to run the JP game is displayed on the shared display  203 . At the timing to run the JP gamer the JP game is run in which a player participates by consuming a JP chance stored in the RAM  243 . A rank is determined according to a result of the JP game and awarded. Based on the determined rank and the timing to run the JP game, a payout of the JP game is determined. The determined payout of the JP game is awarded. 
     As a result of this, a payout of a JP game is determined by a rank determined according to a result of the JP game and a timing to run the JP game. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the shared display  203 , a player is motivated to continue a game thanks to decreased stress on him/her. 
     In the gaming machine  1  of the present embodiment, concurrently run in each gaming terminal  10  which is capable of independently run a game are a base game which is configured to award a payout according to a predetermined combination and a chance game offering a chance of obtaining a JP chance which qualifies a player to join a JP game offering a chance of winning a higher payout than the base game. A payout is determined according to a result of the base game and awarded. In accordance with a result of the chance game, there is determined whether a JP chance is awarded. When a JP chance is awarded, the number of awarded JP chances is stored in the RAM  243  for each gaming terminal  10 , in association with the time of awarding the JP chance specified by the clock IC  280 . A timing to run a JP game is determined in accordance with the timing to award the JP chance. A pointer image  167  based on the timing to run the JP game is displayed on the shared display  203 . At the timing to run the JP game, the JP game is run in which a player participates by consuming a JP chance stored in the RAM  243 . A rank is determined according to a result of the JP game. If the RAM  243  stores a result in the same rank as the determined rank, a lower payout than the payout stored in the RAM  243  is determined as a payout of the JP game. The determined payout of the JP game is stored in the RAM  243  in association with the determined rank, and the determined payout of the JP game is awarded. 
     As a result of the above, a payout of a JP game is determined by a rank determined according to a result of the JP game and a timing to run the JP game. Specifically, a player for whom a JP game is run earlier than for another player receives a higher payout, even if the rank of these players is the same. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the shared display  203 , a player is motivated to continue a game thanks to decreased stress on him/her. 
     In the gaming machine  1  of the present embodiment, concurrently run are a base game which is executed in response to the consumption of a predetermined game value and is configured to award a payout according to a predetermined combination and a chance game offering a chance of obtaining a JP chance which qualifies a player to join a JP game offering a chance of winning a higher payout than the base game. A part of the consumed game value is stored in the RAM  243 . A payout is determined according to a result of the base game and awarded. In accordance with a result of the chance game, there is determined whether a JP chance is awarded. When a JP chance is awarded, the number of awarded JP chances is stored in the RAM  243  in association with the time of awarding the JP chance specified by the clock IC  280 . A timing to run a JP game is determined in accordance with the timing to award the JP chance. A pointer image  167  based on the timing to run the JP game is displayed on the shared display  203 . At the timing to run the JP game, the JP game is run in which a player participates by consuming a JP chance stored in the RAM  243 . A rank is determined according to a result of the JP game. A payout of the JP game is determined according to the determined rank, the timing to run the JP game, and the game value accumulatively stored in the RAM  243 . The determined payout of the JP game is awarded. 
     As a result of this, a payout of a JP game is determined by a rank determined according to a result of the JP game, a timing to run the JP game, and a game value accumulatively stored in the RAM  243 . This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the shared display  203 , a player is motivated to continue a game thanks to decreased stress on him/her. 
     In the gaming machine  1  of the present embodiment, concurrently run in gaming terminals  10  each capable of independently run a game are a base game which is executed in response to the consumption of a predetermined game value and is configured to award a payout according to a predetermined combination and a chance game offering a chance of obtaining a JP chance which qualifies a player to join a JP game offering a chance of winning a higher payout than the base game. A part of the consumed game value is stored in the RAM  243 . A payout is determined according to a result of the base game and awarded. In accordance with a result of the chance game, there is determined whether a JP chance is awarded. When a JP chance is awarded, the number of awarded JP chances is stored in the RAM  243  for each gaming terminal  10 , in association with the time of awarding the JP chance specified by the clock IC  280 . A timing to run a JP game is determined in accordance with the timing to award the JP chance. A pointer image  167  based on the timing to run the JP game is displayed on the shared display  203 . At the timing to run the JP game, the JP game is run in which a player participates by consuming a JP chance stored in the RAM  243 . A rank is determined according to a result of the JP game. If the RAM  243  stores a result in the same rank as the determined rank, a lower payout than the payout stored in the RAM  243  is determined as a payout of the JP game, based on the game value accumulatively stored in the RAM  243 . The determined payout of the JP game is stored in the RAM  243  in association with the determined rank, and the determined payout of the JP game is awarded. 
     As a result of this, a payout of a JP game is determined by a rank determined according to a result of the JP game, a timing to run the JP game, and a game value accumulatively stored in the RAM  243 . This provides players with a new entertainment characteristic. Specifically, a player for whom a JP game is run earlier than for another player receives a higher payout, even if the rank of these players is the same. This provides players with a new entertainment characteristic. 
     Furthermore, since a timing to run a JP game is displayed on the shared display  203 , a player is motivated to continue a game thanks to decreased stress on him/her. 
     Note that this embodiment deals with a case where the JP game is run for a gaming terminal  10  having one or more JP chance; however, the present invention is not limited to this. For example, the JP game may be run for a gaming terminal  10  having three or more JP chances. 
     In the present embodiment, a payout of a JP game for a player is determined based on an accumulatively-stored progressive value. The present invention however is not limited to this arrangement. For example, among players whose payout in response to a JP game is in the same rank, those who are not the first participant of a JP game may receive an initial value of the progressive value. In this case, for example, provided that the accumulative storing of the progressive value starts from 1000 dollars, among players in the same rank a player who has participated in a JP game first receives a payout according to the accumulatively-stored progressive value, whereas all of the players who participate in the JP game second or later receives 1000 dollars. As a result, players are motivated to obtain a JP chance (chance flag) as soon as possible. This further enhances the entertainment characteristic.
