CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority from Japanese application No. 2012-032209, which was filed on Feb. 16, 2012, the entire disclosure of which is herein incorporated by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a gaming machine configured to rearrange symbols after variable-display of the symbols. 
     2. Description of Related Art 
     An example of a known slot machine is disclosed by U.S. Laid-Open Patent Application No. 2011/0250947. This slot machine operates in such a way that, when a player inserts a coin, bill or the like into an insertion slot of a slot machine and presses a spin button, symbols are scroll-displayed on a symbol display area provided on the front surface of a cabinet, and then the symbols are automatically stopped. Based on the state of the stopped symbols, various prizes such as a bonus are established. 
     In such a gaming machine represented by the known slot machine, not only normal games are playable but also the excitement in playing with the gaming machine is enhanced by adding various features such as a bonus game. As such, in the gaming machine what kind of feature is added to games is important to enhance the excitement. 
     An object of the present invention is therefore to provide a gaming machine capable of further enhancing the excitement. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a gaming machine including: a symbol display device configured to variably display symbols and then rearrange the symbols; an input device used for inputting an instruction related to a game; and a controller. The controller is programmed to execute the steps of: 
     (a1) executing a base game by rearranging the symbols on the symbol display device; 
     (a2) allowing the execution of a first bonus game in which a selection game is executable for a predetermined number of times more than once and the next selection game is executable based on a result of the selection game of each time, when a game result of the base game is bonus winning; 
     (a3) for each time of the execution of the selection game in the first bonus game, selecting one of a predetermined number of options associated with selectable game results based on the instruction input by the input device; 
     (a4) ending the first bonus game and returning to the base game if a game result of the selection game of a time in the first bonus game satisfies a first bonus game end condition; and 
     (a5) executing a second bonus game after the end of the first bonus game, if in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition. 
     According to the arrangement above, As such, the gaming machine determines whether the first bonus game is continued (i.e., whether to execute the next selection game) based on the result of the selection game. If in the first bonus game the selection game is executed for a predetermined number of times, the second bonus game can be executed. This provides the player with the pleasure of playing the second bonus game after the first bonus game, in addition to the pleasure of playing the first bonus game. Furthermore, because the selection game is executed based on an input from the player, it is possible to enhance the player&#39;s sense of accomplishment at the time of achieving the second. 
     In addition to the above, the present invention relates to a gaming machine including: a symbol display device configured to variably display symbols and then rearrange the symbols; an input device used for inputting an instruction related to a game; and a controller. The controller is programmed to execute the steps of: 
     (a1) executing a base game by rearranging the symbols on the symbol display device; 
     (a2) allowing the execution of a first bonus game in which a selection game is executable for a predetermined number of times more than once and the next selection game is executable based on a result of the selection game of each time, when a game result of the base game is bonus winning; 
     (a3) for each time of the execution of the selection game in the first bonus game, selecting one of a predetermined number of options associated with selectable game results based on the instruction input by the input device; 
     (a4) ending the first bonus game and returning to the base game if a game result of the selection game of a time in the first bonus game satisfies a first bonus game end condition; 
     (a5) executing a second bonus game after the end of the first bonus game, if in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition; and 
     (a6) executing an indication effect indicating winning of the second bonus game by the indication effect device after the execution of the indication effect for the last time, if in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition. 
     According to the arrangement above, As such, the gaming machine determines whether the first bonus game is continued (i.e., whether to execute the next selection game) based on the result of the selection game. If in the first bonus game the selection game is executed for a predetermined number of times, the second bonus game can be executed. Furthermore, when the second bonus game is to be executed, the indication effect is executed in advance. This provides the player with the pleasure of playing the second bonus game after the first bonus game, in addition to the pleasure of playing the first bonus game. When the indication effect is executed, the expectation to play the second bonus game is provided to the player before the execution of the second bonus game. Furthermore, because the selection game is executed based on an input from the player, it is possible to enhance the player&#39;s sense of accomplishment at the time of achieving the second. 
     In addition to the above, the present invention relates to a gaming machine including: a symbol display device configured to variably display symbols and then rearrange the symbols; an indication effect device configured to execute an indication effect; an input device used for inputting an instruction related to a game; and a controller. The controller is programmed to execute the steps of: 
     (a1) executing a base game by rearranging the symbols on the symbol display device; 
     (a2) allowing the execution of a first bonus game in which a selection game is executable for a predetermined number of times more than once and the next selection game is executable based on a result of the selection game of each time, when a game result of the base game is bonus winning; 
     (a3) for each time of the execution of the selection game in the first bonus game, displaying the predetermined number of options associated with selectable game results in different arrangement areas of the game display device in the same manner, selecting one of the options based on the instruction input by the input device, and determining a selectable game result associated with the selected one of the options as a game result of the selection game; 
     (a4) ending the first bonus game and returning to the base game if a game result of the selection game of a time in the first bonus game satisfies a first bonus game end condition; 
     (a5) executing a second bonus game after the end of the first bonus game, if in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition; and 
     (a6) executing an indication effect indicating winning of the second bonus game by the indication effect device after the execution of the selection game for the last time, if in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition. 
     According to the arrangement above, As such, the gaming machine determines whether the first bonus game is continued (i.e., whether to execute the next selection game) based on the result of the selection game executed based on the input from the player during the first bonus game. If in the first bonus game the selection game is executed for a predetermined number of times, the second bonus game can be executed. Furthermore, when the second bonus game is to be executed, the indication effect is executed in advance. This provides the player with the pleasure of playing the second bonus game after the first bonus game, in addition to the pleasure of playing the first bonus game. When the indication effect is executed, the expectation to play the second bonus game is provided to the player before the execution of the second bonus game. Furthermore, because the selection game is executed such that one of the options displayed in the same manner is selected based on an input from the player, it is possible to enhance the player&#39;s sense of accomplishment at the time of achieving the second bonus game. 
     In the gaming machine of the present invention, in the step (a3), the controller randomly provides the predetermined number of options in the predetermined number of arrangement areas, in each time of the selection game. 
     According to the arrangement above, the predetermined number of options in the selection game are provided in the arrangement areas randomly. This enhances the gaming pleasure of the selection game and further increases the sense of accomplishment in succeeding in the selection game. 
     In the gaming machine of the present invention, in the step (a3), when one of the options is selected, the controller changes the display state of the selected one of the options to a state indicating the selectable game result associated with the selected one of the options. 
     According to the arrangement above, the predetermined number of options in the selection game are provided in the same display state. This enhances the gaming pleasure of the selection game and further increases the sense of accomplishment in succeeding in the selection game. 
     The present invention is capable of further enhancing the excitement in playing with the gaming machine.

     The following will describe a gaming machine of the present invention with reference to figures. 
     (Outline of Gaming Machine) 
     As shown in  FIG. 1 , as a first feature, the gaming machine is arranged to be able to execute a first bonus game in which a selection game may be executed more than once, when the game result of a base game (normal game) is bonus winning. 
     To more specifically describe the first feature, as shown in  FIG. 1 , a gaming machine  300  is a multi-player gaming machine in which a plurality of slot machines  10  that are gaming terminals are connected to a center controller  200  ( FIG. 2  and  FIG. 3 ) to be able to communicate with one another. The gaming machine  300  is able to run a base game such as a slot game at each slot machine  10  and run a common game at a common display device  700  or the like while synchronizing the slot machines  10 . The slot machines  10  and the center controller  200  are connected wireless, by wires, or by both of them. A unit of bet amount may be a currency of a country or area such as dollar, yen, euro, or the like, or may be a game point used exclusively in a hole having the gaming machine  300  or in the industry. 
     Details of the first feature will be given. As shown in  FIG. 2 , a gaming machine  300  includes a lower image display panel  141  (symbol display device) on which symbols are variably displayed and then rearranged and a controller which is programmed to execute processes described below. 
     The steps executed by the terminal controller of the slot machine  10  will be described. The step (a1) is a step for executing a base game by rearranging the symbols on the lower image display panel  141 . The step (a2) is a step for allowing the execution of a first bonus game in which a selection game is serially executable for a predetermined number of times that is more than once and the next selection game is executable based on the result of each selection game, when the game result of the base game is bonus winning. The step (a3) is a step for selecting one of a predetermined number of options associated with selectable game results based on an instruction input to an input device, for each selection game of the first bonus game. The step (a4) is a step for ending the first bonus game and returning to the base game, when the game result of any selection game in the first bonus game satisfies a first bonus game end condition. The step (a5) is a step for executing the second bonus game after the end of the first bonus game, when in the first bonus game the selection game is executed for a predetermined number of times which is more than once, without satisfying the first bonus game end condition. 
     It is noted that the phrase “allowing the execution of a first bonus game” in the step (a2) is not necessarily interpreted that the first bonus game is always executed as a result of the bonus winning. For example, one of a plurality of bonus games including the first bonus game is selectable as a result of the bonus winning. 
     In the meanwhile, the phrase “first bonus game in which a selection game is serially executable for a predetermined number of times” in the step (a2) indicates that, in the first bonus game, the selection game is serially executable for a predetermined number of times which is more than once at the maximum (eight times in the present embodiment). That is to say, when the first bonus game end condition is established in the selection game of the first time, the selection game is not repeated any more and the first bonus game ends. In addition to the above, the phrase “the next selection game is executable based on the result of each selection game” indicates that whether to execute the next selection game is determined based on the result of the selection game of one time. 
     In addition to the above, the term “selectable game results” in the step (a3) are prepared in advance as results of the selection game. That is to say, in the selection game, one of a plurality of selectable game results is selected and the selected selectable game result becomes the game result of that selection game. One selectable game result may include more than one content. For example, one selectable game result may indicate a payout of a predetermined amount (fixed payout) and the end of the first bonus game. In addition to the above, the input device in the present embodiment indicates buttons and a touch panel  69  of a later-describe control panel  30 . The player is able to select a desired option by making input to the input device. Alternatively, an option is randomly selected at the timing of the operation by the player, for example. 
     In the present embodiment, first bonus game end (which may be referred to as END) is included as one of six options. That is to say, when “selectable game result” corresponding to the selected option includes the first bonus game end, the first bonus game end condition is satisfied. 
     The phrase “when in the first bonus game the selection game is executed for a predetermined number of times which is more than once, without satisfying the first bonus game end condition” in the step (a5) indicates a case where the selection game is repeatedly executed and the number of times of the execution of the selection game reaches a predetermined number which is more than one, while the “selectable game result” indicating the first bonus game end is not selected in the selection game of each time. In the present embodiment, the second bonus game is not executed when the game result of the selection game indicates the first bonus game end after the number of times of the execution of the selection game has reached the predetermined time which is more than one. In addition to the above, the phrase “returning to the base game” indicates the shifting to a state in which the base game is executable, and does not always indicate that the base game is executed. Furthermore, the phrase “returning to the base game” indicates a state in which at least the first bonus game and second bonus game are not executed. 
     In the present embodiment, the first bonus game is a later-described Vampire BONUS. In the Vampire BONUS, a 6-option selection game (pickup bonus or pickup bonus game) is executed. The second bonus game is a later-described Franken BONUS. 
     The gaming machine is not limited to the arrangement in which only the first bonus game and the second bonus game are the types of the bonus game. For example, a free game may be executed under a predetermined condition, in addition to the first bonus game and the second bonus game. The selection game may be the same type each time or may be a different type at least once. 
     In addition to the above, as shown in  FIG. 1  to  FIG. 3 , the common game may be run in place of the base game, or the base game and the common game may be simultaneously run. Furthermore, while in the present embodiment the gaming machine  300  includes the center controller  200  in addition to the slot machines  10 , the disclosure is not limited to this arrangement. The gaming machine  300  may be arranged such that one or more slot machine  10  has the function of the center controller  200  and the slot machines  10  are connected to be able to communicate with one another. Alternatively, the gaming machine may be a single slot machine  10 . 
     (Outline of Gaming Machine: Definitions) 
     The slot machine  10  above is a kind of the gaming terminals in the gaming machine  300 . Although the present embodiment deals with the slot machine  10  as an example of the gaming terminal, the disclosure is not limited to this and any type of device having a terminal controller that is able to independently run a base game may be used as the gaming terminal. 
     The base game in the present embodiment is run by the slot machine  10 . The base game is a slot game of rearranging a plurality of symbols  501 . The base game is not limited to the slot game but is any type of games capable of being independently run at a gaming terminal such as the slot machine  10 . In other words, the base game is a game in contrast to the common game. For example, a normal game and a bonus game that are described later are types of the base game. 
     The rearrangement of the symbols in the slot game is performed on the lower image display panel  141 . The slot game includes a process of running a normal game of rearranging symbols on the lower image display panel  141  on condition that a gaming value is bet and awarding a normal payout based on the rearranged symbols, a process of running a bonus game of rearranging symbols with the assumption that the payout rate is higher than that of the normal game when the rearranged symbols achieve a predetermined condition and awarding a bonus payout based on the rearranged symbols, and a process of executing a rescue process when a rescue start condition is established. 
     Symbols  501  are constituted by a specific symbol  503  and a normal symbol  502 . In other words, the symbol  501  is a superordinate concept to the specific symbol  503  and the normal symbol  502 . The specific symbol  503  includes a wild symbol  503   a  and a trigger symbol  503   b . The wild symbol  503   a  can be used as a substitute for any type of the symbol  501 . The trigger symbol  503   b  is a symbol that triggers at least the execution of the bonus game. For example, the trigger symbol  503   b  functions as a trigger to shift the normal game to various types of the bonus game. 
     The trigger symbol  503   b  may function as a trigger of increase in the number of the specific symbols  503  in the bonus game, i.e., increase in the number of the specific symbols  503  of at least one of the trigger symbol  503   b  and the wild symbol  503   a . Furthermore, the trigger symbol  503   b  may function as a trigger of increase in the number of times to run the bonus game. 
     A coin, a bill, or electrically valuable information corresponding to these is used as a gaming value. The gaming value may be a game point not related to any monetary value. The coin may be a medal used exclusively for games. It is to be noted that the gaming value in the disclosure is not limited to these, and for example a medal, a token, electric money or the like can be adopted. Further, a later-described ticket with a barcode is also used. 
     The bonus game is equivalent to a feature game. In the present embodiment, there are at least four types of the bonus games. More specifically, as shown in  FIG. 4 , there are four types of the bonus game, namely, “Franken BONUS”, “Mummy BONUS”, “Wolfman BONUS”, and “Vampire BONUS”. These types of the bonus games are selectable in a 4-option pickup bonus game, and the shifting to each type is performed by the selection by the player. The 4-option pickup bonus game is run when three trigger symbol  503   b  appear (are rearranged) in a normal game. 
     The Franken BONUS is a 29-option bonus using the top box  12 , the lower image display panel  141  or the like of the slot machine  10 . In the Franken BONUS, as shown in  FIG. 5 , one of a fixed payout, a door  2  options game, a mini game  1 , a mini game  2 , and END is selectable. Details will be given later. 
     As shown in  FIG. 4 , the Mummy BONUS is a 5-option-pick bonus. The Mummy BONUS is a fixed-credit bonus and occurs only once. Furthermore, the Mummy BONUS may develop into the Franken BONUS at the end of the bonus. The Wolfman BONUS is a free game and develops into the Franken BONUS at the end of the bonus. The Vampire BONUS is a 6-option pickup bonus and a fixed-credit bonus. The Vampire BONUS ends when the END occurs and is repeated eight times at the maximum. The Vampire BONUS may develop into the Franken BONUS. Furthermore, the Vampire BONUS may develop into the Franken BONUS at the end of the bonus. 
     In addition to the above, another type of the bonus game is an expand wild feature. This bonus game occurs in a mystery effect (i.e., no bonus symbol appears on the reel  3 ), and shifts to various types of wild bonus. The types of the wild bonus are a mummy wild feature (expand wild feature  1 ), a wolfman wild feature (expand wild feature  2 ), and a vampire wild feature (expand wild feature  3 ). The mummy wild feature is a bonus game of changing symbols on one row or plural rows to Wild. The wolfman wild feature is a bonus game of changing one or more symbol to the Wild and executing an after-scattering process. The vampire wild feature is a bonus game of changing one or more symbol to the Wild and executing a before-scattering process. Details of the various types of the bonus game above will be described later. 
     While the bonus game in the present embodiment is described as games with the names described above, the bonus game is not limited to them but is any type of game as long as the gaming state is more advantageous than that of the normal game. Other types of the bonus game may be employed as long as the gaming state is advantageous for the player, i.e., the gaming state is more advantageous than that of the normal game. For example, in the bonus game, various states such as a state in which more gaming values can be achieved as compared to the normal game, a state in which the probability of obtaining a gaming value is higher than the probability in the normal game, and a state in which the number of consumed gaming values is smaller than in the normal game are achieved independently or in combination. 
     The first bonus game and the second bonus game include the above-described types of the bonus game. The first bonus game and the second bonus game may be of the same type or different types. 
     A free game is a game which is executable with a smaller amount of gaming values bet than in the normal game. The expression “executable with a smaller amount of gaming value bet” includes a case where an amount of gaming values bet is zero. Therefore, the free game may be a game which is run without betting a gaming value and the gaming value is paid out for an amount corresponding to rearranged symbols  501 . In other words, the free game may be a game that starts even if no gaming value is consumed. On the other hand, the normal game is run on condition that a gaming value is bet, and is a game of paying out gaming value for an amount corresponding to rearranged symbols  501 . In other words, the normal game is a game that starts with the consumption of the gaming value. 
     The term “rearrangement” indicates that the a symbols  501  are rearranged after the arrangement of the symbols  501  is dismissed. The term “arrangement” indicates a state in which the symbols  501  are visually recognizable by an external player. 
     The phrase “normal payout based on the rearranged symbols  501 ” indicates a normal payout corresponding to a winning combination resulting from the rearrangement. The phrase “bonus payout based on the rearranged symbols  501 ” indicates a bonus payout corresponding to a winning combination resulting from the rearrangement. It is noted that the term “winning combination” indicates that a prize is established. Details of the winning combination will be given later. 
     Examples of “a condition in which the payout rate is higher than in the normal game” include the execution of a free game, increase in the number of the wild symbol  503   a  and the trigger symbol  503   b , and the execution of a game using a symbol table. Examples of “rescue start condition” includes a case where the normal game is excessively repeated, i.e., the normal game is repeated for a predetermined number or more of times and a case where the total amount of obtained payout is excessively small, i.e., the obtained normal payout and bonus payout is smaller than a predetermined amount after a single player repeats the game for a predetermined number or more of times. The rescue process is a process to relieve players. Examples of the rescue process include the execution of a free game, the increase in the number of the wild symbol  503   a  and the trigger symbol  503   b , the execution of a game using a substituted symbol table, and the awarding of an insurance payout. 
     (Outline of Gaming Machine: Other Arrangements) 
     As shown in  FIG. 1 , the gaming machine  300  may be configured so that, in addition to the first feature, an indication effect device executing various types of indication effects are executed and the terminal controller executes the step (a6) below. The step (a6) is a step of executing an indication effect indicating the winning of the second bonus game by the indication effect device after the last execution of the selection game, when in the first bonus game the selection game is executed for a predetermined number of times which is more than once without satisfying the first bonus game end condition. Examples of the indication effect device include a lower image display panel  141 , an upper image display panel  142 , and an effect mechanism  131 . 
     The phrase “indication effect indicating the winning of the second bonus game” indicates either a second bonus game becomes executable after the end of the first bonus game or an indication effect indicating the winning of the second bonus game is executed after the end of the first bonus game. 
     In addition to the above, the gaming machine  300  may include an input device used for inputting instructions regarding games and a game display device which is able to display a predetermined number of options in the predetermined number of arrangement areas, and the terminal controller may execute the following process in the step (a3). That is to say, the terminal controller may, for each time of the selection game in the first bonus game, display a predetermined number of options associated with the selectable game results on different arrangement areas of the game display device in the same manner, select one of the options based on an instruction input to the input device, and determine the selectable game result associated with the selected option as the game result of the selection game. 
     In addition to the above, the gaming machine  300  may be arranged so that, in the step (a3), a predetermined number of options are randomly provided in the predetermined number of arrangement areas, in each time of the selection game. 
     In addition to the above, the gaming machine  300  may be arranged so that, in the step (a3), when one of the options is selected, the display state of the selected option is changed to the state indicating the selectable game result associated with that option. 
     As such, the gaming machine  300  determines whether the first bonus game is continued (i.e., whether to execute the next selection game) based on the result of the selection game executed based on the input from the player during the first bonus game. If in the first bonus game the selection game is executed for a predetermined number of times, the second bonus game can be executed. When the second bonus game is to be executed, an indication effect is executed in advance. 
     This provides the player with the pleasure of playing the second bonus game after the first bonus game, in addition to the pleasure of playing the first bonus game. When the indication effect is executed, the expectation to play the second bonus game is provided to the player before the execution of the second bonus game. Furthermore, because the selection game is executed such that one of the options displayed in the same manner is selected based on an input from the player, it is possible to enhance the player&#39;s sense of accomplishment at the time of achieving the second bonus game. 
     In addition to the above, the predetermined number of options in the selection game are provided in the arrangement areas randomly and/or in the same display state. This enhances the gaming pleasure of the selection game and further increases the sense of accomplishment in succeeding in the selection game. 
     In addition to the above, the gaming machine  300  may have a feature that the slot machine  10  further includes a symbol display device as a terminal display device, and the slot machine  10  executes a process of displaying a movie related to the common game during a period between the output of a common game start command to the center controller  200  and the receiving of game result information from the center controller  200 . With the gaming machine  300  having the feature above, the attention of each player is turned to the common game because the movie related to the common game is displayed during a period of waiting for the game result information. 
     In addition to the above, the gaming machine  300  may include a common display device  700  which is provided to be viewable from operation positions of all slot machines  10 , and the center controller  200  may display a state until the establishment of a common game start condition on the common display device  700 . It is noted that the operation position is the eye level position of the player operating each slot machine  10 . With the gaming machine  300  having the feature above, it is possible to allow each player to estimate the waiting time until the common game starts, as the state until the establishment of the common game start condition is displayed on the common display device  700 . 
     (Outline of Gaming Machine: Game Control Operation) 
     The gaming machine  300  having the arrangement above realizes a gaming method in which, when the game result of a base game (normal game) is bonus winning, a first bonus game in which a selection game is executed more than once is executed. In other words, the gaming machine  300  is arranged to be operable at least by a game control method in which a first bonus game in which a selection game is executable more than once is executed when the game result of a base game (normal game) is bonus winning. 
     More specifically, according to the gaming method and the game control method of the gaming machine  300 , the following processes are executed: a process of executing a base game by variably displaying symbols and rearranging the symbols on the lower image display panel  141 , a process of causing a first bonus game in which a selection game is serially executable for a predetermined number of times which is more than once and the next selection game becomes executable based on the result of each selection game to be executable when the game result of the base game is bonus winning, a process of selecting one of a predetermined number of options associated with the selectable game results based on an instruction input to an input device, for each time of the selection game in the first bonus game, a process of ending the first bonus game and returning to the base game when the game result of the selection game of one time in the first bonus game satisfies a first bonus game end condition, and a process of executing a second bonus game after the first bonus game end when in the first bonus game the selection game is executed for the predetermined number of times without satisfying the first bonus game end condition. 
     The details of the control operation will be described with reference to the flowchart of  FIG. 1 . To begin with, while the base game is being executed (ST 1 ), whether winning of a bonus is achieved is determined, and when winning the bonus (ST 2 ), the first bonus game becomes executable. When the first bonus game starts, the selection game of the first time is executed (ST 31 ). In the selection game, a plurality of options are displayed on the lower image display panel  141 . The options are randomly displayed in the same manner. Based on an input to an input device such as buttons and a touch panel  69  of the control panel  30 , one of the options is selected. The options are associated with selectable game results, respectively. In the present embodiment, each selectable game result is one of “Payout of 100 Credits”, “Payout of Credits”, and “Payout of 30 Credits and First Bonus Game End (END)”, but is not limited thereto. When one of the options is selected, the state of that option is changed to the state of indicating the associated selectable game result. For example, a text showing the selectable game result is displayed. Furthermore, according to the present embodiment, the options not selected in the selection game are changed to the state of indicating the associated selectable game results and the areas in each of which the state is displayed are grayed out. The disclosure, however, is not limited to this arrangement. 
     When the result of the selection game indicates the establishment of the first bonus game end condition, the first bonus game ends (ST 4 ). That is to say, assume that the selection game is executed for N times at the maximum. For example, when the game result of the selection game of the M-th time (N&gt;M) is the establishment of a first bonus end condition, the selection game of the remaining (N-M) times are not executed and the first bonus game ends. Therefore the base game comes back without the execution of the second bonus game. On the other hand, when the game result of the selection game of the M-th time is not the establishment of a first bonus end condition, the selection game of the next M+1 time is executed. As such, until the first bonus game end condition is established, the selection game of the first time (ST 31 ), the selection game of the second time (ST 32 ), the selection game of the third time (ST 33 ), . . . , the selection game of the seventh time (ST 37 ), and the selection game of the eighth time (ST 38 ) are serially executed. While the present embodiment is arranged so that the selection game is executable eight times, the disclosure is not limited to this arrangement. 
     When the selection game of the eighth time (last selection game) ends while the first bonus game end condition has not ever been established, the second bonus game is executed (ST 5 ). That is to say, when the game result of the selection game of the N-th time is the establishment of the first bonus end condition, the first bonus game ends without the execution of the second bonus game. On the other hand, when the game result of the selection game of the N-th time is not the establishment of the first bonus end condition, the second bonus game is executed. Before the execution of the second bonus game, an indication effect indicating that the second bonus game is to be executed is executed (ST 6 ). In the present embodiment, the effect image of this indication effect is an image a runaway vampire is chased and is displayed on the lower image display panel  141 . The disclosure, however, is not limited to this arrangement. 
     The first bonus game (Vampire BONUS) will be detailed later with reference to  FIG. 127  to  FIG. 134 . 
     (Indication Effect) 
     The details of the indication effects of the bonus of the gaming machine  300  will be given. As shown in  FIG. 6 , the indication effects of the bonus includes a common indication effect and an individual indication effect. The common indication effect is a former stage indication effect that appears first after the start of the variable display of the symbols  501 , i.e., after the start of the rotation of the reels. The common indication effects include three types of the indication effects, namely a silhouette indication effect ( FIG. 7 ), a red window indication effect ( FIG. 8 ), a tomb indication effect ( FIG. 9 ). These types of the common indication effect are executed when it is randomly determined that the indication is to be executed, at the start of the rotation of the reels. Furthermore, when an indication is to be executed, the type of the common indication effect is randomly determined. For example, a probability of being judged that there is an indication is 1/144, a probability that the silhouette indication effect is to be executed is 1/483, a probability that the red window indication effect is to be executed is 1/436, and a probability that a tomb indication effect is to be executed is 1/388. 
     After the start of the common indication effect above, the individual indication effect is executed. The individual indication effect is a latter stage indication effect that appears after the start of the common indication effect. The individual indication effect includes two types of indication effects, namely, a door close indication effect and a dark change indication effect. The door close indication effect is an effect of closing a door, whereas the dark change indication effect is an effect of closing a door and changing the screen to dark before and after the closure of the door. The appearance probabilities of the latter-stage door close indication effect and the dark change indication effect as compared to the former-stage silhouette indication effect are 8:2. The appearance probabilities of the latter-stage door close indication effect and the dark change indication effect as compared to the former-stage red window indication effect are 7:3. The appearance probabilities of the latter-stage door close indication effect and the dark change indication effect as compared to the former-stage tomb indication effect are 6:4. 
     The door close indication effect is an individual indication effect is an indication effect of the 4-option pickup bonus game and is an indication effect of the vampire wild feature. The 4-option pickup bonus game and the vampire wild feature are executed at the appearance probabilities of 3.5:6.5 after the door close indication effect. On the other hand, the dark change indication effect is an indication effect of the mummy wild feature and also is an indication effect of the wolfman wild feature. The mummy wild feature and the wolfman wild feature are executed at the appearance probabilities of 5:5 after the dark change indication effect. 
     When it is determined that no indication is to be performed at the start of the rotation of the reels, a common indication effect which is the former stage indication effect is not executed, and an individual indication effect which is the latter stage indication effect is immediately executed. In other words, the door close indication effect or the dark change indication effect is executed. After the door close indication effect, the 4-option pickup bonus game or the vampire wild feature is executed at the appearance probabilities of 3.5:6.5. In the meanwhile, after the dark change indication effect, the mummy wild feature or the wolfman wild feature is executed at the appearance probabilities of 5:5. 
     In addition to the above, the individual indication effect includes a 1 ghost passing effect ( FIG. 10 ), a 3 ghost passing effect ( FIG. 11 ), a ghost group passing effect ( FIG. 12 ), a thunder and castle effect ( FIG. 13 ), a thunder effect ( FIG. 14 ), and a Franken mum effect ( FIG. 15 ). These individual indication effects are exclusive for the 4-option pickup bonus game. It is noted that the thunder and castle effect ( FIG. 13 ), the thunder effect ( FIG. 14 ), and the Franken mum effect ( FIG. 15 ) are displayed across the entire width of the lower image display panel  141 . The other effects may be displayed across the entire width of the lower image display panel  141 , or all effects may be executed inside the display window  150 . 
     (Details of Indication Effects: Individual Indication Effects of 4-Option Pickup Bonus Game) 
     As shown in  FIG. 16 , after the reel spin at which the symbols  501  starts the variable display (ST 20 ), whether a bonus trigger is established is randomly determined with reference to a stop table. When the bonus trigger is not established (ST 21 ), a random determination table  1  is referred to (ST 22 ). Thereafter, one of the no effect (ST 25 ), the 1 ghost passing effect (ST 26 ), the 3 ghost passing effect (ST 27 ), and the thunder effect (ST 29 ) is executed. 
     On the other hand, when the bonus trigger is established (ST 23 ), a random determination table  2  is referred to (ST 24 ). Then one of the no effect (ST 25 ), the 1 ghost passing effect (ST 26 ), the 3 ghost passing effect (ST 27 ), the ghost group passing effect (ST 28 ), the thunder effect (ST 29 ), the thunder and castle effect (ST 30 ), and the Franken mum effect (ST 31 ) is executed. 
     More specifically, when the bonus trigger is not established (ST 21 ), an indication is randomly determined with reference to the table  1  shown in  FIG. 18 . The table  1  is referred to when two bonus symbols are stopped (rearranged). This condition is “Bonus Tenpai” with which a bonus will be established when one more bonus symbol stops, and is “blank”. In the rearrangement state with which the condition above is established, the bonus symbols each functioning as a trigger stop at the reel  1  and the reel  3  whereas no bonus symbol stops at the reel  2 . 
     When the table  1  is referred to, as shown in  FIG. 19 , the probabilities of the random determination of the indication are: 85% for the indication  0 , 6% for the indication  1 , 3% for the indication  2 , 0% for the indication  3 , 6% for the indication  4 , 0% for the indication  5 , and 0% for the indication  6 . In this connection, as shown in  FIG. 17 , the indication  0  corresponds to the no effect, the indication  1  corresponds to the 1 ghost passing effect, the indication  2  corresponds to the 3 ghost passing effect, the indication corresponds to the ghost group passing effect, the indication  4  corresponds to the thunder and castle effect, the indication  5  corresponds to the thunder effect, and the indication  6  corresponds to the Franken mum effect. 
     In the meanwhile, when the bonus trigger is established (ST 23 ), the random determination of the indication is carried out with reference to a table  2  shown in  FIG. 18 . The table  2  is referred to when three bonus symbols stop. When this condition is established, the 4-option pickup bonus game is run. In the rearrangement state with which the condition above is established, the bonus symbol each functions as a trigger stops at the reel  1 , the reel  3 , and the reel  5 . When the table  2  is referred to, as shown in  FIG. 19 , the probabilities of the random determination of the indication are: 33% for the indication  0 , 10% for the indication  1 , 10% for the indication  2 , 4% for the indication  3 , 10% for the indication  4 , 13% for the indication  5 , and 20% for the indication  6 . 
     The relationship among the occurrence probabilities (%) of the indication  0  to the indication  6  randomly determined as above, the occurrence probability (1/N) of each effect, the reliability of each effect, and the share of each effect in the winning is shown in a table of  FIG. 20 . For example, the occurrence probability (%) of the indication  1  which is the 1 ghost passing effect is 0.52%, the occurrence probability (1/N) of each effect is 193.24%, the reliability of each effect is 32.61%, and the share of each effect in the winning is 10.00%. With this, the indication is executed in accordance with a flow shown in  FIG. 21 . 
     (Details of Indication Effect: Common Indication Effect) 
     As shown in  FIG. 22 , after the reel spin of stating the variable display of the symbols  501  (ST 40 ), when a bonus trigger is established as a result of the random determination based on a stop table, the type of the bonus trigger is specified. After the execution of the common indication effect corresponding to the specified type of the bonus starts, the random determination table  3  shown in  FIG. 24  is referred to and the type of the individual indication effect is randomly determined (ST 41 ). When the individual indication effect is the dark change effect (ST 42 ), then either the mummy wild feature (ST 44 ) or the wolfman wild feature (ST 45 ) is executed. In the meanwhile, when the individual indication effect is the door close effect (ST 43 ), either the vampire wild feature (ST 46 ) or the 4-option pickup bonus game (ST 47 ) is executed. As such, because the common indication effect is executed as an indication of the individual indication effect, the indication effects are the same partway, even in different types of the bonus. 
     More specifically, as shown in  FIG. 23 , when a bonus trigger is established as a result of the start of the spin and the random determination of the rearrangement, a table shown in  FIG. 23  is referred to and whether to execute the common indication effect is randomly determined. For example, when the bonus trigger of the mummy wild feature is established, the probability of executing the indication is 16% whereas the probability of not executing the indication is 84%. 
     When the indication is executed, a data table associated with each type of the bonus is referred to. More specifically, when the bonus trigger of the mummy wild feature is established, a data table  4  shown in  FIGS. 26A, 26B, and 26C  is referred to. When the bonus trigger of the wolfman wild feature is established, a data table  6  shown in  FIGS. 28A, 28B, and 28C  is referred to. When the bonus trigger of the Vampire BONUS is established, a data table  8  shown in  FIGS. 30A, 30B, and 30C  is referred to. When the bonus trigger of the 4-option pickup bonus game is established, a data table  10  shown in  FIGS. 32A, 32B , and  32 C is referred to. 
     For example, when the bonus trigger of the mummy wild feature is established, as shown in a table  4  of  FIGS. 26A, 26B, and 26C , the random determination is executed with the probabilities of 47% for the indication  0 , 33% for the indication  1 , and 20% for the indication  2 . The indication  0 , the indication  1 , and the indication  2  in the table  4  are a tomb indication effect, a red window indication effect, and a silhouette indication effect, respectively. As such, the incidences and the reliabilities of the indications are as shown in the data table of  FIG. 27 . 
     When the bonus trigger of the wolfman wild feature is established, as shown in a table  6  of  FIGS. 28A, 28B , and  28 C, the random determination is executed with the probabilities of 47% of the indication  0 , 33% for the indication  1 , and 20% for the indication  2 . The indication  0 , the indication  1 , and the indication  2  of the table  6  corresponds to the tomb indication effect, the red window indication effect, and the silhouette indication effect, respectively. As such, the incidences and the reliabilities of the indications are as shown in the data table of  FIG. 29 . 
     In the meanwhile, when the bonus trigger of the vampire wild feature is established, as shown in a table  8  of  FIGS. 30A, 30B, and 30C , the random determination is executed with the probabilities of 33% for the indication  0 , 33% for the indication  1 , and 34% for the indication  2 . The indication  0 , the indication  1 , and the indication  2  in the table  8  are the tomb indication effect, the red window indication effect, and the silhouette indication effect, respectively. As such, the incidences and the reliabilities of the indications are as shown in the data table of  FIG. 31 . 
     When the bonus trigger of the 4-option pickup bonus game is established, as shown in the table  10  of  FIGS. 32A, 32B, and 32C , the random determination is executed with the probabilities of 33% for the indication  0 , 33% for the indication  1 , and 34% for the indication  2 . The indication  0 , the indication  1 , and the indication  2  in the table  10  are the tomb indication effect, the red window indication effect, and the silhouette indication effect, respectively. With this, the incidences and the reliabilities of the indication are as shown in the data table of  FIG. 33 .

Furthermore, the payout unit  620  has a function of adding credit data corresponding to the credit to be paid out to credit data stored in an IC card inserted into the later-described PTS terminal  700 . 
     The indication effect unit  651  has a function of executing an indication effect indicating the winning of the second bonus game during the execution of the first bonus game (when the last selection game is executed). The indication effect unit  651  may have a function of executing various indication effects at predetermined probabilities and a function of executing an indication effect that indicates the winning of various types of bonus game and indicates a type of the bonus game. Furthermore, the indication effect unit  651  may have a function of, when rearrangement information of the symbols  501  is obtained, determining or randomly determining whether to execute various indication effects based on the rearrangement information and a function of executing the various indication effects on the display  614  by using output mechanisms such as the speaker  617  and the lamp  618  of the top box  12 . 
     In addition to the above, the game controller  100  includes a storage unit  661  that stores various types of bet amount data. The storage unit  661  stores data in a rewritable manner, e.g., a hard disc device and a memory. 
     In addition to the above, the game controller  100  has a common game running unit  653 . The common game running unit  653  has functions of: outputting bet amount information based on a bet amount bet on a normal game to the external controller  621  in each unit base game; executing a common game in response to a game start command from the external controller  621 ; and receiving a bet input through the BET button  601  for a bet amount corresponding to bet amount data for a common game, which is stored in the storage unit  661  and is bettable on a common game. 
     In addition to the above, the game controller  100  is connected to the PTS terminal  700 . The PTS terminal  700  is a unit in which an LCD, a microphone, a human body detection camera, etc. are integrated, and has, for example, a function of executing an effect for a game by mutual communications with the game controller  100 . In particular, the PTS terminal  700  has a card slot to which an IC card can be inserted. With this, the player is able to insert a IC card into the card slot and use the credits stored in the IC card in the slot machine  10 . The mechanical structure of the PTS terminal  700  will be described later. 
     In addition to the above, when receiving credit data from the PTS terminal  700 , the game controller  100  updates the credit display on the display  614 . Furthermore, the game controller  100  outputs settled credit data too the PTS terminal  700  when the credits on a game are settled. 
     Furthermore, the PTS terminal  700  of each of the slot machines  10  constituting the gaming machine  300  is connected to the management server  800  to be able to communicate each other, and centrally manages the download of images, IC cards and credits. 
     (Function Flow of Gaming Machine  300 : External Controller) 
     The slot machine  10  arranged as above is, as shown in  FIG. 3 , connected to the external controller  621 . The external controller  621  has a function of remotely operating and monitoring the operation state of each slot machine  10  and processes such as changes in game setting values. Furthermore, the external controller  621  has a function of determining a common game start condition for each gaming terminal which is the slot machine  10 , and executing a common game at a plurality of slot machines  10  when a determination result at any gaming terminal satisfies the common game start condition. 
     More specifically, the external controller  621  includes a common game start unit  6213 , a gaming terminal selection unit  6215 , and a transceiver unit  6217 . The common game start determining unit  6213  has functions of: determining whether the common game start condition is established based on the accumulated bet amount information sent from the slot machine  10  in each unit base game; outputting a game start command to a plurality of slot machines  10 ; and displaying on the common display device  700  states until the common game start condition is established. 
     The determination as to whether the common game start condition is established is based on the accumulated bet amount information or based on all accumulated values that increase as the unit base game is repeated. For example, the number of times of running the base game and the game time of the base game may be used as the accumulated values. 
     In addition to the above, the common game start unit  6213  has a function of outputting a game start command to the slot machine  10  in which an accumulated value that increases as a result of the repetition of the base game satisfies a game running condition. With this, because the right to participate in the common game is not awarded to a slot machine  10  in which the accumulated value is lower than the minimum setting value, the common game start unit  6213  motivates the player to actively repeat the base game. 
     In addition to the above, the common game start unit  6213  has a function of monitoring a non-input time in which no start operation is performed, and outputting the game start command to the slot machines  10  except to the slot machine  10  in which the non-input time is equal to or longer than a timeout time. With this, the common game start unit  6213  is able to determine that no player is at a slot machine  10  where the base game has not been played at least for the timeout time, and able to avoid the execution of the common game at such a slot machine  10 . 
     The gaming terminal selection unit  6215  has a function of selecting a specific slot machine  10  from the slot machines  10  and outputting a common game start command signal to that specific slot machine  10 . The common game start command signal provides the specific slot machine  10  with the right to start the common game. The transceiver unit  6217  has a function of exchanging data with the slot machines  10 . 
     (Operations of Gaming Machine  300 ) 
     The operations of the gaming machine  300  having the functional blocks above will be described. While in the present embodiment the “gaming terminal” shown in the flowcharts indicates a slot machine  10  executing a slot game, the disclosure is not limited to this arrangement. 
     (Operations of Slot Machine  10 ) 
     A slot machine  10  which is a gaming terminal executes terminal-side processes (A 1 ) to (A 7 ). More specifically, to begin with, a base game process (e.g., normal game) is executed (A 1 ). That is, a series of operations below are executed. 
     (Coin-Insertion/Start-Check) 
     First, the slot machine  10  checks whether or not a BET button  601  has been pressed by a player, and subsequently checks whether or not a spin button  602  has been pressed by the player. 
     (Symbol Determination) 
     Next, when a spin button unit  602  has been pressed by the player, the slot machine  10  extracts a random number for symbol determination, and determines symbols  501  to be displayed for the player at the time of stopping the scroll of the symbol array, for respective video reels displayed on a display unit  614 . 
     (Symbol Display) 
     Then the slot machine  10  starts the scroll of the symbol array of each video reel, and stops the scroll so that the determined symbols  501  are displayed for the player. 
     (Winning Determination) 
     Subsequently, as the rotation of the symbol array of each video reel is stopped, the slot machine  10  determines whether the combination of the symbols  501  displayed for the player is a combination related to winning. 
     (Payout) 
     When the combination of the symbols  501  displayed for the player is a combination related to winning, the slot machine  10  offers, to the player, benefit according to the combination. 
     For example, when a combination of symbols  501  related to a payout of coins has been displayed, the slot machine  10  pays out coins of the number corresponding to the combination of symbols  501  to the player. 
     Subsequently, whether to win a bonus combination is determined. When winning the bonus combination, a bonus game process is executed. On the other hand, when not winning the bonus combination, the normal game is run again. During a period in which the base game including such a normal game and bonus game is being run, execution state information indicating the start and end of the unit game such as the normal game and the bet amount on the unit game is transmitted to the external controller  621 . With this, the external controller  621  centrally manages the execution state information of each slot machine  10 . 
     (Operation of External Controller  621 ) 
     When the slot machines  10  operate as above, the external controller  621  executes the following center-side processes in synchronization with the slot machines  10 . 
     To begin with, the external controller  621  receives the execution state information from each slot machine  10  and obtains the execution state of the base game. Thereafter, based on the number of the repetition of the base game, the accumulated bet amount, or the like, whether the common game start condition is established at any slot machine  10  is determined. When the common game start condition is not established, the acquisition of the execution state of the base game at each slot machine  10  is continued. 
     In the meanwhile, when the common game start condition is established, the game start command is simultaneously output to the slot machines  10  that satisfy the game running condition. Thereafter, a specific slot machine  10  is selected from the slot machines  10  satisfying the game running condition, and a common game start right instruction is output to the specific slot machine  10  (B 4 ). 
     Thereafter, the external controller  621  waits for the common game start command to be supplied from the specific slot machine  10 . Upon receiving the common game start command, the result of the common game is determined as a game result. The game result is, for example, win, lose, or draw. When the game result is not draw, at least a part of a draw game result is skipped among a series of temporarily-stored game results, and the remaining game results are serially output to the slot machines  10 , as game result information. 
     Thereafter, based on the winning or losing game result, whether to win in the common game is determined. When lost, the execution state of the base game at each slot machine  10  is newly obtained. On the other hand, when won, a payout amount is calculated based on the bet amount bet on the common game at each slot machine  10 , and the payout amount is sent to each slot machine  10  as payout information. 
     (Overall Structure of Game System)

The screen displayed on the lower image display panel  141  has a display window  150  at the central portion. The display window  150  is constituted by 15 display blocks  28  forming a matrix of 5 columns and 3 rows. The three display blocks  28  of each column form pseudo reels  151  to  155 . On each of the pseudo reels  151  to  155 , three display blocks  28  move downward with changes in speed, so that the symbols  501  on the display blocks  28  are vertically rotated (variably displayed) and then stopped, in other words, the symbols are rearranged. The details of the display screen on the lower image display panel  141  will be given later. 
     While the present embodiment the slot machines  10  are so-called video slot machines, some mechanical reels in the slot machines  10  of the present invention may be replaced by the pseudo reels  151  to  155 . 
     On the front surface of the symbol display device is provided a touch panel  69 . The touch panel  69  allows a player to input various instructions by touching the display screen of the lower image display panel  141 . The input signal is transmitted from the touch panel  69  to the main CPU  71 . 
     Below the lower image display panel  141  is provided a control panel  30 . The control panel  30  is provided with buttons, a coin entry  21  for inserting coins into the cabinet  11 , and a bill entry  22 . Details of the control panel  30  will be given later. 
     On the lower front surface of the main door  13 , i.e., below the control panel  30 , a belly glass  132  on which a character of the slot machine  10  or the like is depicted are provided. Between the lower image display panel  141  and the control panel  30 , the PTS terminal  700  is attached. In the PTS terminal  700 , devices having a microphone function, a camera function, a speaker function, a display function and the like form a single unit. More specifically, the PTS terminal  700  includes an LCD, a human detection camera, a microphone, a bass reflex speaker, or the like. The human detection camera makes it possible to detect the presence of a player by the camera function. The microphone is used for the player&#39;s participation in a game by voice and the authentication of a player by voice recognition. The speaker produces sound effects in games and outputs notification sound when an IC card is left inserted. Furthermore, the speaker outputs notification sound when an inserted IC card is not authenticated. 
     In addition to the above, the PTS terminal is provided with an LED and a card insertion slot. The LED emits light with plural colors to notify the remaining number of IC cards in a card stacker. The card insertion slot has a mechanism of allowing IC cards to be inserted and ejected. The IC card has a display region. The IC card is completely inside the machine when the player is playing games, and is ejected to expose the display region at the time of the settlement. This allows the player to recognize the credit-related data such as updated money data. Alternatively, the IC card may be arranged to expose the display region not to be completely inserted, even when the player is playing games. This allows the player to always recognize the update of the credits during games. 
     When it is confirmed by the human detection camera that no player is present at the time of the settlement of the credits, the IC card is drawn into and stored in the card stacker. With this arrangement, the IC card is not left inserted for a long time, even if the player left the machine without taking the IC card after recognizing that the remaining credits on the display region are small. 
     (Slot machine: Mechanical Structure of Top Box  12 ) 
     On the upper part of the slot machine  10  is provided the top box  12 . The top box  12  has a three-dimensional form representing the appearance of Franken mum. The top box  12  is provided with an effect mechanism  131  (output mechanism). The effect mechanism  131  is used for the common indication effect, the individual indication effect, and game effects executed in games. The effect mechanism  131  has, at the forefront, a transparent liquid crystal panel or semi-transparent protection panel. In the present embodiment, an upper image display panel  142  having the same functions as the lower image display panel  141  is provided. 
     In addition to the above, the effect mechanism  131  includes a light effect unit  1311  having LEDs emitting light with changing colors, a mechanically-operating mechanical effect unit  1312 , and a light display unit  1313  having plural LEDs. These effect units  1311 ,  1312 , and  1313  are provided on the back side of the upper image display panel  142 . The LEDs of the light effect unit  1311  are provided, for example, at around the chin of the Franken mum and at the matrix parts below the chin. The mechanical effect unit  1312  is provided below the light display unit  1313  to allow the shadow of each character to be swung. 
     The LEDs of the effect mechanism  131  are, as shown in  FIG. 38 , divided into 6 categories to be controlled (i.e., controlled based on different csv files). In regard to the LEDs of the effect mechanism  131 , a scene where the lighting pattern is changed during the progress of a game is defined as “event”. A folder is provided for each event, and four csv files are provided in each folder for the respective categories. More specifically, the category  1  corresponds to the face and the surrounding of the face of the Franken mum, the category  2  corresponds to payouts, the category  3  corresponds to the door, and the category  4  corresponds to always-on. 
     In addition to the above, the top box  12  is provided with speakers  112  and  112  (output mechanisms) that are symmetrical crosswise. The slot machine  10  executes the effect by outputting images, sound, and light, by means of the speakers  112  and the effect mechanism  131 . For example, the speakers  112  and the effect mechanism  131  execute an effect by outputting light, sound or the like in sync with an effect of images displayed on the lower image display panel  141  in the common indication effect and the individual indication effect. For example, these units are used for the effects in Franken BONUS: a roulette random determination game. Furthermore, an effect by the top box  12  is executed in sync with a thunder and castle effect ( FIG. 13 ) and a Franken mum effect ( FIG. 15 ). 
     As such, the slot machine  10  is able to execute, as an indication effect by displaying an image on the symbol display device, at least one of indication effects including the thunder and castle effect and the Franken mum effect, and uses the effect mechanism  131  such as the LEDs of the top box  12  for the effect, in sync with the indication effect by the image. In other words, the slot machine  10  executes an image indication effect and a mechanical indication effect. More specifically, in the indication effect of the thunder and castle effect, the light emitted from the LEDs of the top box  12  moves in vertical directions. That is to say, as the operation of turning on an upper LED and turning off a lower LED and then turning off the upper LED and turning on the lower LED is repeated, the effect representing thunder is executed. Furthermore, in the indication effect of the Franken mum effect, the LEDs provided at the mouth of the Franken mum turn on and off in sync with the lines uttered by the Franken mum.

     (Symbols, Combinations, or the Like) 
     The symbols  501 , which are displayed on pseudo reels  151  to  155  of the slot machine  10 , form a symbol array. Each symbol  501  constituting the symbol array has, as shown in  FIG. 40 , one of the code numbers  0  to  19  or more. Each symbol array is a combination of the symbols  501  such as “WILD”, “BONUS”, “CANDLE”, “BAT”, and “GHOST”. 
     The three successive symbols  501  in the symbol array are, as shown in  FIG. 37 , displayed (provided) at the upper stage, the central stage, and the lower stage of the display region of each of the pseudo reels  151  to  155 , so that a symbol matrix of 5 columns and 3 rows is formed on the display window  150 . The symbols  501  forming the symbol matrix start to scroll at least when a game starts in response to the pressing of the spin button  46 . After a predetermined time elapses from the start of the scroll, the scroll of the symbols  501  stops (rearrangement). 
     In addition to the above, for the symbols  501 , various winning combinations are set in advance. A winning combination indicates that an award is established. A winning combination is a combination in which symbols  501  having stopped on a payline L is advantageous for the player. The advantageous state indicates states such as a state that coins corresponding to the winning combination are paid out, a state that the number of coins to be paid out is added to the credits, and a state that a bonus game starts. 
     The winning combination in the present embodiment is a combination in which a predetermined number or more of symbols  501  of at least one type are rearranged on an activated payline L. When a particular type of symbols  501  is set as a scatter symbol, a winning combination is established when a predetermined number or more of such scatter symbols are rearranged, no matter whether a payline L is activated or not. 
       FIG. 37  shows a table that relates to the normal game and is used for determining which symbols  501  are the targets of rearrangement. In the normal game symbol table, symbols  501  on the display blocks  28  in each symbol array are associated with code numbers, and 20 numerical ranges defined by dividing a numerical range of 0 to 65535 by 20 are associated with the respective code numbers. 
     The numerical range of 0 to 65535 may be equally or unequally divided. When unequally divided, it is possible to adjust the probabilities of wining for the respective types of the symbols  501  by determining the ranges of the random numbers. In this regard, the ranges corresponding to the “BONUS” of the trigger symbol  503   b  of the specific symbol  503  and the “WILD” of the wild symbol  503   a  may be arranged to be narrower than the ranges of the other types of the symbols  501 . In this case, results of games can be easily adjusted in accordance of the progress of the games, by arranging valuable types of the symbols  501  to be less likely to be won. 
     For example, when a random number randomly selected for the first column is “10000”, the symbol  501  having the code number associated with the random number range including the selected random number is chosen as the target of rearrangement on the pseudo reel  151  of the first column. On the other hand, when, for example, a random number for the fourth column is “40000”, the symbol  501  having the code number associated with the random number range including the selected random number is chosen as the target of rearrangement on the pseudo reel  151  of the fourth column. 
     (Gaming Terminal Management Table) 
       FIG. 41  shows a gaming terminal management table by which the state of the base game at each slot machine  10  is managed in the center controller  200 . This management table has a gaming terminal field, a game type field, a game state field, and an accumulated number of games field. The gaming terminal field stores a machine number unique to each slot machine  10 . For example, when 5 slot machines  10  are connected, the machine numbers “001” to “005” are stored. 
     The game type field stores the type of the base game being run by each slot machine  10 , in association with the machine number. Examples of the types of the base game include “normal game” and “bonus game”. For example, at the slot machine  10  having the machine number “001”, the unit game of the normal game is repeated because the game type field indicates “normal game”. 
     The game state field stores the state of the base game being run by each slot machine  10 , i.e., the gaming state of the unit game in association with the machine number. The gaming states are “execution” and “stop”. For example, because the game type is “normal game” and the game state is “stop”, the slot machine  10  having the machine number of “002” is in a state in which the result of the unit game of the normal game has been determined and the next unit game has not started. In the meanwhile, because the game type is “bonus game” and the game state is “execution”, the slot machine  10  having the machine number “004” is in a state in which the unit game of the bonus game is being run. 
     The accumulated number of games field stores, as an initial value, a time at which the slot game restarts after the end of the common game, and stores, as an accumulated number of games, the accumulated number of times of running the unit game in the normal game. The accumulated number of games of each slot machine  10  is used for calculating the total accumulated number of games by which a common game feasible condition is determined, such that the accumulated numbers of games of all slot machines  10  are added up. 
     (Display Screen of Lower Image Display Panel  141 ) 
     An example of the display screen of the lower image display panel  141  in the operation process of the slot machine  10  above will be specifically described.

In the meanwhile, the win meter  402  is provided at the right edge part when viewed from the player. Between the bet meter  401  and the win meter  402 , a system font area  403   c  is provided. The system font area  403   c  has, in an upper stage and a lower stage, a bet information display region  403   a  and a game state display region  403   b , respectively. 
     The credit meter  400  displays the total number of credits. The default value is 0. The value is increased and decreased as follows: When “take WIN”, which indicates winning in a game, is achieved, the credit won in the game is added to the credit meter. When a game is played, the bet number is subtracted from the credit meter. The bet number is also subtracted when the collect ends. 
     The bet meter  401  displays “Total Bets (=Bets x Lines)”. The value is re-calculated in each game play. The win meter  402  displays the total obtained credits in an increment manner. The default value is 0. The win meter  402  switchably displays “Line XX Win XX” or “Total Win XX”. The display is switched in sync with the display of payline at the time of the occurrence of winning. The content above is displayed after the occurrence of winning. The values are determined based on the payline at the occurrence of winning and the number of credits. Details of the win meter  402  will be given later. 
     The bet information display region  403   a  displays the bet information of a game (or the last game). In the first line, the number of bets per line is displayed. The display content is either singular or plural in line with the number of bets. More specifically, in case of one credit per line in the first line, “CREDIT” is displayed when the number of bets per line is 1. In the meanwhile, in case of two credits per line, “CREDITS” is displayed when the number of bets per line is 1. This content is displayed at the time of button selection by the player. 
     The game state display region  403   b  displays a current state of the game. A state display message is not displayed during the game, and the message “GAME OVER” is displayed when the game is over. When Gamble is waited for, “PLAY ON, GAMBLE or TAKE WIN” is displayed. The message is displayed until a button operation instructing Play-on or Gamble is conducted during the idle state or after the occurrence of winning. 
     In the meanwhile, below the display window  150  are provided a help touch button  410 , a language switching touch button  411 , a sound volume switching touch button  412 , a denomination button  413 , a number of lines selection touch button  414 , and a bet per line selection touch button  415 . These buttons  410 ,  411 ,  412 ,  413 ,  414 , and  415  are provided left to right when viewed from the player. 
     The help touch button  410  displays the first page of the help screen  4101  when touched. The help touch button  410  is darkened when it is inactivated, e.g., during the rotation of the reels. The button is displayed when the normal screen is displayed. The button disappears in the help screen  4101 , the free game screen and the double-up screen. 
     As the language switching touch button  411  is touched, the language is switched between English and Chinese. The language switching touch button  411  is activated only during the advertisement, and is darkened when it is invalidated, e.g., during the rotation of the reels. 
     The sound volume switching touch button  412  is used for switching the game sound volume at three stages. Each time the button is touched, the game sound volume is switched such that, for example, low→middle→high→small→middle. The button is displayed when the normal screen is displayed. The button disappears when the help screen  4101  is displayed. 
     The denomination button  413  displays the current denomination set in the AUDIT. This button is displayed when screens other than the AUDIT are displayed. 
     The number of lines selection touch button  414  is used for increasing or decreasing the number of paylines L. In the present embodiment, this button is arranged not to be touchable because the number of lines is fixed to 30. 
     The bet per line selection touch button  415  makes it possible to conduct bet per line. When the button is touched, five selection buttons corresponding to the current bet configuration appear. 
     (Details of Display Screen: Payline Box) 
     The lower image display panel  141  described above forms, as shown in  FIG. 43 , payline boxes in the display window  150 . As the payline boxes forming three rows and five columns are combined, 30 paylines L are formed. Furthermore, as shown in  FIG. 44 , at the left and right edges of the display window  150 , payline occurrence columns are provided in a symmetrical manner on the left and right. The left payline occurrence column on the left side when viewed from the player has 15 payline occurrence parts  65 L. The right payline occurrence column on the right side when viewed from the player has 15 payline occurrence parts  65 R. 
     The left payline occurrence parts  65 L form pairs with the respective right payline occurrence parts  65 R. From the left payline occurrence parts  65 L to the right payline occurrence parts paired with the left payline occurrence parts  65 L, paylines L are defined in advance. The paylines L are associated with the above-described payline boxes. 
     A payline L is activated when left and right payline occurrence parts  65 L and  65 R are connected with each other. In other cases, the paylines are inactive. The number of activated paylines L is determined based on a bet amount. When the bet amount is maximum, i.e., MAXBET, the upper limit of, i.e. 30 paylines are activated. An activated payline L allows the symbols  501  to establish various types of winning combinations. 
     (Details of Display Screen: Displaying Line) 
     Displaying of the lines at the occurrence of winning is carried out in the following cases: (1) during the normal game, (2) during the free game, (3) in the normal game when the free game is obtained (with a trigger), (4) in the normal game when a mystery bonus is obtained (non-trigger), (5) and when re-trigger is obtained. 
     (Details of Display Screen: Displaying Line: When Winning is Achieved at a Single Line) 
     As an example of cases where a wining is achieved at a single line, when, as shown in  FIG. 45 , a winning is achieved at the line  2  in a 3-line game, the following two single line processes  1  and  2  are executed. That is to say, in the single line process  1 , the line where the winning is achieved and the frame enclosing the target symbol are illuminated (but not flicker). In the single line process  2 , the animation of the symbol which is the target of winning starts. In a winning involving a scatter symbol such as the bonus symbol, only the frame enclosing the symbol is displayed. The line display is continued until the next game starts. In the gray display region in the figure, the symbol display is below the payline L. 
     In the free game, each of the single line processes  1  and  2  is executed at least once. After the end of these processes, whether the WIN increment has been finished and whether the waiting time has been elapsed are checked, and the shifting to the next game is conducted when both of these conditions are satisfied. In case of a minor WIN (in a single line or the like), since the execution of each of the single line processes  1  and  2  once finishes promptly and the next game starts, the state at the occurrence of winning is maintained for five seconds, and the shifting to the next game starts after five seconds elapse. The instructions “Skip” and “Cancellation of WIN Increment” by the player while the winning line is illuminated (WIN increment) are accepted and the corresponding operations are performed. This, however, is carried out only when these functions are available. 
     (Details of Display Screen: Displaying Lines: When Winning is Achieved at Plural Lines) 
     As an example of cases where winning is achieved at plural lines, as shown in  FIG. 46 , when in the 3-line game winning is achieved at the lines  1  and  2 , plural line processes  1 ,  2 , and  3  are executed. In the plural line process  1 , the lines where the winning is achieved are illuminated for one second one by one. Furthermore, the animations of all symbols that are the target of winning are continued. The line WIN is serially performed from the line having the smallest line number. When a bonus WIN not related to the lines occurs, the effect of this bonus WIN is executed first. In so doing, the win meter  402  displays “bonus WIN=XXXXX”. In the gray display region, the symbol display is provided below the payline L. 
     In the plural line process  2 , as shown in  FIG. 47 , the next target line is illuminated for one second. Furthermore, the animations of all symbols that are the target of winning are continued. In the gray display region, the symbol display is provided below the payline L. 
     In the plural line process  3 , the plural line process  1  which is the first line display is carried out again after the display of all lines finishes. The line display in accordance with the plural line processes  1 ,  2 , and  3  is repeated until the next game starts. 
     Each winning line is illuminated during the free game, and whether the WIN increment has finished and where the waiting time has been elapsed are checked after the illumination of all winning lines finishes. The shifting to the next game is conducted when both of these conditions are satisfied. The instructions “Skip” and “Cancellation of WIN Increment” by the player while the winning line is illuminated (WIN increment) are accepted and the corresponding operation is performed. This, however, is carried out only when these functions are available. 
     (Details of Display Screen: Displaying Lines: When 5-Of-A-Kind WIN Occurs) 
     Irrespective of the grade of the combination, video and sound effects are executed when the symbols  501  form 5 of a kind. The sound volume is changed in accordance with the type of the combination. For example, as shown in  FIG. 48 , a 5 of a kind is achieved when the reel stops. Thereafter, the image and sound of the 5 of a kind are output. More specifically, “5 OF A KIND” is displayed and, the voice pronouncing “5 OF A KIND” is reproduced. This process cannot be skipped. Furthermore, the increment display and the line display are not executed at this stage. Then a payout occurs. More specifically, the increment of the payout is carried out and the line WIN is displayed. This process can be skipped. 
     (Details of Display Screen: Displaying Lines: When Big WIN Occurs) 
     The following effect is executed in accordance with the payout rate of the winning. One of these types of texts is displayed. The animation operates in the same manner in both cases. Winning with the payout ratio of 10/1 to 25/1 is termed “High Payout”. In the meanwhile, winning with the payout rate of 1/25 or higher is termed “Great”. 
     The following will described a case where 5 of a kind is not achieved. For example, as shown in  FIG. 49 , winning with 10/1 or higher and smaller than 25/1 occurs when the reel stops. Then the increment display starts and “Big WIN”, a Big WIN dedicated meter (large meter), and the line WIN are displayed. Displaying them can be skipped. The speed of the increment display in the Big WIN dedicated meter is carried out in accordance with the increment operation in the win meter  402 . Details of the increment operation will be given later. When three seconds have elapsed after the end of the increment, the Big WIN and the large meter disappear. The line WIN is displayed continuously. 
     The following will describe a case where a 5 of a kind is achieved. For example, as shown in  FIG. 50 , winning with 10/1 or higher and smaller than 25/1 occurs when the reel stops.

     (Details of Display Screen: WIN Meter  402 : Increment) 
     (Basic Setting) 
     The count up is smoothly carried out upward. The control is executed in consideration of a difference between an actual amount of money (real amount of money) and an amount of money displayed at that time (displayed amount of money). The operation of the carry of a digit is done at the same time as the operation for lower digits. When a displayed amount of money is larger than a real amount of money (e.g., at the time of resetting in response to a winning), rewriting is immediately carried out. 
     (Details of Increment Operation) 
     The speed of the increment is determined in accordance with a remaining count number. When the remaining count number is increased during the operation, the speed of the increment is immediately changed to correspond to the increased remaining count number. The rewriting is performed when the remaining count number exceeds “101”. More specifically, as shown in  FIG. 52 , the increment operation is carried out at a speed of increment (seconds) corresponding to each remaining count number. 
     (Details of Rewriting) 
     When the remaining count number exceeds “101”, the rewriting is carried out with the value (remaining count number −60), and the count up is carried out based on a data table for the remaining 60 counts. For example, when the remaining count number is 110 counts, the target amount is rewritten so that 50 counts calculated by subtracting 60 from 110 are added to the target amount. At the same time as the rewriting, the remaining 60 counts are counted up. In the meanwhile, when the display amount becomes larger than the real amount due to resetting on account of progressive winning or the like, rewriting is immediately carried out. It is noted that the numbers above such as “101” and “60” are mere examples, and “101” may be any predetermined number and “60” may be any number to be subtracted. 
     When a progressive winning occurs, the increment is interrupted, the rewriting to the amount of money having been won is carried out, and a flickering effect starts. The flickering is not performed while the increment is being interrupted. 
     The speed of increment may be managed based on the ratio between the bet and the amount won. For example, when an amount won by winning is four times larger than a bet, the speed of the increment is set at four seconds with reference to the relationship between control thresholds and seconds defined in, for example, a data table shown in  FIG. 53 . Furthermore, after the speed of the increment is determined based on the data table of  FIG. 53 , the data table of  FIG. 53  may be rewritten based on the determined value. For example, when the speed of the increment is determined to be four seconds in the case where an amount won by winning is four times larger than the bet as above, the second for the remaining count number (1 to 2) in the data table of  FIG. 53  is set at four seconds, and the other remaining count numbers are changed to values calculated based on a predetermined ratio. 
     (Details of Display Screen: Sound Volume Switching Touch Button  412 ) 
     As shown in  FIG. 54 , the sound volume switching touch button  412  has a function of allowing the player to switch the sound volume at will. The volume is switchable in, for example, three stages. The volume may be linearly changeable. The first stage corresponds to the minimum volume. The second stage corresponds to the medium volume. The third stage corresponds to the maximum volume. The volume stages are switched such that the first stage→second stage→third stage→first stage. 
     The default volume stage is the first stage. The default bonus stage is set when (1) a game is activated and (2) at the return from the AUDIT (regardless of whether the volume in the AUDIT is changed). The coefficients of volume changes are 30% in the first stage, 70% in the second stage, and 100% in the third stage. The sound volume switching touch button  412  is always activated unless the button is hidden. The button is activated when GUI (Graphical User Interface) such as the help touch button  410  is displayed. However, when a help screen is displayed, the sound volume switching touch button  412  disappears from the GUI (i.e., is covered with the NEXT button), the button is not operable. The operation invalidation time of the sound volume switching touch button  412  after the touch, i.e., the minimum interval between serial touching is 0.15 second (150 msec). The default sound volume setting value in the AUDIT is 12. The default value is 5 when no sound volume adjustment touch panel function is provided. The reproduction sound volume of the volume setting change sound in the AUDIT is identical with the default volume of the sound volume switching touch button  412  (i.e., the volume reflecting the coefficient in the default stage).

     (Operations of Slot Machine  10 : Normal Game Execution Process) 
     The operation of the slot machine  10  arranged as above will be described. The normal game execution process shown in  FIG. 94  is executed by the main CPU  71  of the slot machine  10 . The slot machine  10  has been activated in advance. 
     To begin with, the main CPU  71  executes a credit request process (S 10 ). In this process, the player determines how many credits are used from the credits stored in the IC card. 
     Then whether a coin is bet is determined (S 11 ). In this process, the main CPU  71  determines whether an input signal output from the 1-BET switch  34 S when the 1-BET button  34  is pressed and an input signal output from the 10-BET switch  39 S when the 10-BET button  39  is pressed are received. When it is determined that no coin is bet, the process goes back to S 10 . 
     In the meanwhile, if it is determined in S 11  that a coin is bet, the main CPU  71  executes a process of decreasing the number of credits stored in the RAM  73  in accordance with the number of coins bet (S 12 ). When the number of coins bet is larger than the number of credits stored in the RAM  73 , the step of decreasing the number of credits stored in the RAM  73  is not carried out and the process goes back to S 11 . When the number of coins bet is larger than the maximum number (maximum bet amount in the present embodiment) of coins on one game, the step of decreasing the number of credits stored in the RAM  73  is not carried out and the process proceeds to S 13 . 
     Then the main CPU  71  determines whether the spin button  46  is pressed (S 13 ). In this step, the main CPU  71  determines whether an input signal output from the start switch  46 S when the spin button  46  is pressed is received. When it is determined that the spin button  46  is not pressed, the process goes back to S 11 . It is noted that, when the spin button  46  is not pressed (e.g., when an instruction to end a game is input while the spin button  46  is not pressed), the main CPU  71  cancels the reduction result in S 12 . 
     In the meanwhile, if it is determined in S 13  that the spin button  46  is pressed, the main CPU  71  sends terminal-side game information to the center controller  200  (S 14 ), and then executes a normal game symbol determination process (S 15 ). In the normal game symbol determination process, code numbers when the symbols are stopped are determined. More specifically, a random number is sampled, and the code number when each symbol array of the display block  28  stops is determined based on the sampled random number and a normal game symbol table shown in  FIG. 37 . 
     Thereafter, in S 16 , the main CPU  71  executes a scroll-display control process. In this process, the display control is conducted so that, after the start of the scroll of the symbols  501 , the symbols  501  are rearranged in accordance with S 15 . 
     Thereafter, the main CPU  71  determines whether a prize is established (S 17 ). In S 17 , the main CPU  71  counts, regarding the symbols  501  rearranged in accordance with S 16 , the number of symbols  501  of each type rearranged on each payline L. Then the main CPU  71  determines whether the number of the symbols of each type is at least two. 
     When it is determined that a prize is established, the main CPU  71  executes a step concerning the payout of coins (S 18 ). In this step, the main CPU  71  determines a payout rate with reference to odds data stored in the RAM  73  and based on the number of symbols  501  rearranged on a payline L. The odds data indicates the relationship between the number of symbols  501  rearranged on a payline L and a payout rate. Each time one “Wild” is displayed on a payline L where winning is established, the payout is doubled. That is to say, when three “Wild” are displayed on a payline L where winning is established, the payout is multiplied eight times. 
     The present embodiment assumes that a prize is established when at least one type of two or more symbols  501  are rearranged on a payline L. Alternatively, the present invention may be arranged so that no payline L is provided and a prize is established when at least one type of two or more symbols  501  are rearranged in the display blocks  28 . 
     When it is determined in S 17  that no prize is established or after S 18 , the main CPU  71  executes a rescue process to relieve the player if a predetermined rescue execution condition has been established (S 22 ). After S 22 , the main CPU  71  sends game end information as information to cause all slot machines  10  to simultaneously start the common game (S 23 ). Thereafter, a terminal-side common game process is executed (S 24 ). The sub routine ends with this. 
     (Operations of Slot Machine: Bonus Game Execution Process) 
     As shown in  FIG. 4 , in the normal game (B 1 ), the execution of the mummy wild feature (B 2 ) is triggered by a randomly-appearing mummy, on condition that no bonus symbol appears on the third reel. When the mummy appears, all symbols on a randomly selected reel, the number of which is four at the maximum, are changed to the wild symbols. It is noted that the mummy wild feature (B 3 ), the wolfman wild feature (B 4 ), and the vampire wild feature (B 5 ) do not simultaneously occur. 
     In the normal game (B 1 ), the execution of the wolfman wild feature (B 4 ) is triggered by a randomly-appearing wolfman, on condition that no bonus symbol appears on the third reel and no wild symbol has not appeared. When the wolfman appears, the after-scattering process is executed so that three to seven randomly-selected symbols are changed to the wild symbols. 
     In addition to the above, in the normal game (B 1 ), the execution of the vampire wild feature (B 5 ) is triggered by a randomly-appearing vampire, on condition that no bonus symbol appears on the third reel. When the vampire appears, the before-scattering process is executed so that three to seven randomly-selected symbols are changed to the wild symbols. 
     In addition to the above, when in the normal game (B 1 ) a bonus symbol stops at reel  1 ,  3 , or  5 , a 4-option pickup bonus (B 2 ) is triggered and four doors are displayed on the display screen. Behind the four doors, a Franken BONUS (B 6 ), a Mummy BONUS (B 7 ), a Wolfman BONUS (B 8 ), and a Vampire BONUS (B 9 ) are hidden. One of the four doors is selected and the shifting to the bonus game appearing at the selected door is conducted. 
     The Mummy BONUS (B 6 ) is a 5-option fixed payout. The bonus shifts to the Franken BONUS (B 10 ) when developed, or shifts to the normal game (B 13 ) when not developed. The Wolfman BONUS (B 7 ) is a five-time free game. The bonus shifts to the Franken BONUS (B 11 ) when developed, or shifts to the normal game (B 13 ) when not developed. The Vampire BONUS (B 8 ) is a 6-option selection game, and END (game end) or continue occurs. The bonus shifts to the Franken BONUS (B 12 ) when developed, or shifts to the normal game (B 13 ) when not developed. 
     The Franken BONUS (B 9 ) is, as shown in  FIG. 5 , 29-option selection game. The 29-option selection game results in a fixed payout (H 1 ) at the probability of 18/29. The 29-option selection game results in a door  2  options game (H 2 ) at the probability of 3/29. In a 2-option game in the door  2  options game (H 2 ), the shifting to the Franken BONUS (H 10 ) is conducted when unsuccessful, whereas a monster is obtained, i.e., the right to play a roulette random determination game (H 9 ) is obtained when successful. On the other hand, in a 1-option game (H 8 ) in the door  2  options game (H 2 ), a monster is always obtained, i.e., the right to play the roulette random determination game (H 9 ) is always obtained. After the roulette random determination game (H 9 ), the shifting to the Franken BONUS (H 10 ) is conducted. 
     The 29-option selection game results in a mini game (H 3 ) at the probability of 1/29. The mini game  1  (H 3 ) is a number place game and the shifting to the Franken BONUS (H 11 ) is conducted after the game ends. The 29-option selection game results in a mini game  2  (H 4 ) at the probability of 2/29. The mini game  2  (H 4 ) is a random payout system and the shifting to the Franken BONUS (H 12 ) is conducted after the game ends. 
     The 29-option selection game results in END (game end) at the probability of 5/29. If a monster has been obtained, a roulette random determination game (H 21 ) is executed. On the other hand, when no monster has been obtained, a 4-option tombstone selection game (H 13 ) is executed. In the tombstone selection game (H 13 ), a monster is obtained at the probability of 1/4 and a roulette random determination game (H 14 ) is executed. In addition to the above, in the tombstone selection game (H 13 ) a 10-option revival bonus game (H 15 ) is executed at the probability of 1/4, a fixed payout (H 16 ) is executed at the probability of 2/4, and the shifting to the normal game is conducted. 
     In the revival bonus game (H 15 ) a monster is obtained at the probability of 1/10 and a roulette random determination game (H 17 ) is executed. In the revival bonus game (H 15 ) a fixed payout (H 18 ) is executed at the probability of 8/10, and the revival bonus game (H 20 ) is continued. In the revival bonus game (H 15 ), END (H 19 ) is executed at the probability of 1/10, and the bonus game end and the shifting to the normal game is executed. 
     (Operations of Slot Machine  10 : Mummy Wild Feature) 
     When in the normal game no bonus symbol appears on the third reel and the mummy appears, a mummy wild feature is executed. That is to say, as shown in  FIG. 95 , the steps are executed in the following order: reel spin (F 1 )→the indication effect (F 2 )→the appearance of mummy (F 3 )→Wild arrangement (F 4 )→reel stop (F 5 )→WIN process (F 6 ). 
     More specifically, the mummy wild feature occurs when no bonus symbol stops at the third reel and winning is achieved in Wild EXPAND occurrence random determination. When winning in the occurrence random determination, as a process  1 , which reel is to be changed to Wild when a feature occurs is randomly determined. In a process  2 , a character appears during the reel rotation, and a randomly-selected reel is changed to Wild reel. Then the reel stops. When a plurality of reels are changed to Wild, the order of the execution of the effects is randomly determined. 
     The normal effect in the mummy wild feature is executed with the steps (a) to (f) shown in  FIG. 96 . (a) The reel is rotating normally. (b) A mummy appears from below the reel. (c) The mummy wraps the reel by a bandage. (d) As the bandage is unwrapped, a tentative wild symbol appears. (e) After the effect, it is changed to a wild symbol (Mum).

The voice counting ends when the counter reaches “100”. After this, the counting is conducted by a sound effect. The maximum value of the counter is “999”. 
     The fourth free game region  1   d  displays the total number of free games. The initial value is “5”. The counter is incremented by five at the re-trigger, and the enlargement effect is carried out. At the same time as the enlargement effect, an effect of illuminating the first free game region  1   a  is conducted. The maximum value is “999”. Alternatively, the maximum value is 10. When the re-trigger occurs and the total number of free games is larger than “999”, the number exceeding 999 is truncated and the count-up process is not conducted any more. 
     In the process  3 , “BONUS REELS IN PLAY” is always displayed in the lower right part of the screen. This may be covered on account of the enlargement of the free game counter  1  or symbol animation. The text above is preferably displayed on the free game counter  1 . When reel strips different from those in the free game are used, such different is clearly shown in the help and the notice is noticeably displayed during the free game. 
     In the process  4 , the reel variation may be different from that of the normal game. In the process  5 , the re-trigger is conducted only once. No payout occurs with a free game symbol of the second and subsequent times. In the process  6 , an WIN effect is conducted at the occurrence of winning, in the same manner as the normal game. In addition to the above, an increment process and a line effect are conducted. The lines and bet in the free game are identical with those at the occurrence of the free game.

On the other hand, when the end with no credit has occurred (F 81 : YES), a WIN process screen is displayed (F 86 ) and a total WIN signboard is displayed (F 87 ). Thereafter, the title of the Franken BONUS is displayed (F 88 ) and the shifting to the Franken BONUS is conducted. 
     More specifically, as shown in  FIG. 117 , the Wolfman BONUS game is divided into an introduction stage, a during free game stage, a result screen stage, and a re-trigger stage. In the introduction stage, as shown in  FIG. 118 , the screen “WOLFMAN FREE GAMES 5 FREE GAMES” is displayed and then the screen “FREE GAMES START” is displayed. Thereafter, in the during free game stage, as shown in  FIG. 119 , the reels are changed to those with symbols and arrangement dedicated to the free game. Then the “BONUS REELS IN PLAY” is displayed and a text explaining that special reels different from those in the normal game are used is displayed. Below the text, a free game counter showing “FREE GAME xx OF xx” is displayed. The maximum digits of the free game counter are two (the maximum number is 10). 
     In the result screen stage, as shown in  FIG. 120 , when the development to the Franken BONUS does not occur and the end with one or more credit occurs, a “common total WIN signboard” is displayed and then the normal game screen comes back. On the other hand, when the development to the Franken BONUS does not occur and the end with no credit occurs, the text “No WIN signboard display” is displayed after the fifth reel which is the last reel stops the rotation. After a predetermined waiting time (with dedicated background music), the normal game screen comes back. 
     In addition to the above, as shown in  FIG. 121 , when the development to the Franken BONUS occurs and the end with one or more credit occurs, a WIN process is executed after the fifth reel which is the last reel stops the rotation. Thereafter, an effect in which the Franken mum chases the running wolfman is executed. Subsequently, a dedicated with-mum total WIN signboard is displayed and the shifting to the Franken BONUS is conducted. 
     In the meanwhile, as shown in  FIG. 122 , when the development to the Franken BONUS occurs and the end with no credit occurs, a WIN process is executed after the fifth reel which is the last reel stops the rotation. Thereafter, an effect in which the Franken mum chases the running wolfman is executed. Subsequently, a dedicated with-mum total WIN signboard is displayed and the shifting to the Franken BONUS is conducted. 
     As shown in  FIG. 123 , when in the re-trigger stage three bonus symbols stop in the free game, the re-trigger display is conducted. However, the re-trigger is conducted only once. Then the number of free games is increased by five (10 in total). For a bonus symbol that stops after the re-trigger, bonus stop sound is not output (i.e., normal sound is output). 
     (Operations of Slot Machine  10 : 4-Option Pickup Bonus Game→Wolfman Bonus: Fixation of Wild and Related Process) 
     AS shown in  FIG. 124 , when in the free game a Wild stops on the screen at the stop of each reel, the fixation of Wild and related process are executed. More specifically, when a wild symbol stops on the screen, the Wild design is changed from the symbol design “before transformation to wolfman” to the symbol design “wolfman”. That is to say, to begin with, the reels up to the fifth reel stop and animation showing a change of the wild symbol with the wild animal design is changed to the wild symbol with the prince design. After the animation showing the change, an WIN effect (or the start of the next game) is conducted after a predetermined second of waiting time. The waiting time is preferably adjustable. The next game starts while the Wild stops at the same position and the wolfman design is fixed. Note that, because the layout of the reels remains the same, only the wolfman symbol is fixed and the before-transformation symbol continues to exist. The symbol with the wolfman design is kept fixed until the end of the free game. 
     For example, as shown in  FIG. 124( a ) , when the reels up to the fifth reel completely stop, as shown in  FIG. 124( b ) , the before-transformation design is changed to the wolfman design. Thereafter, as shown in  FIG. 124( c ) , WIN animation is executed if there is a winning. Subsequently, as shown in  FIG. 124( d ) , the next game starts while the wolfman design symbol is kept fixed. The wolfman design symbol is kept fixed until the end of the free game. 
     In addition to the above, when a wild symbol has already been fixed on a reel, the fixed wild symbol is preferentially displayed. The reel passes through the position below the fixed wild symbol. Until all reels stop, even 3-of-a-kind bonus symbols pass under the Wild. 
     In addition to the above, when a bonus symbol stops below a fixed wild symbol, the fixed Wild is preferentially displayed if both of the fixed Wild and the bonus symbol do not relate to winning. If the bonus symbol relates to winning or both of the fixed Wild and the bonus symbol relate to winning, the bonus symbol winning is preferentially displayed at the time of displaying the winning line, and then the symbol rotates and the wild symbol is displayed. This operation is repeated while the winning line is displayed. In this regard, with the bonus symbol, the re-trigger is conducted only once and no payout is awarded. The effect is therefore executed only once in the free game. Assuming that three free game symbols are rearranged, as shown in  FIG. 125( a )  for example, a free game symbol stops below a fixed wild symbol when the reels up to the fifth reel completely stop. Thereafter, as shown in  FIG. 125( b ) , the WIN animation of the bonus symbol is reproduced for once. Thereafter, as shown in  FIG. 125 ( c ) , the symbol rotates (is turned inside out) and a fixed wild symbol is displayed. When the wild symbol relates to a winning, the WIN animation of the Wild is reproduced and repeated until the next game starts. When the “free game” is won and a payout is awarded as a result of “Wild”, the rotational display is conducted. On the other hand, when “free game” is won but no payout is awarded by the “Wild”, the operation of fading in and fading out each symbol is repeated. 
     (Operations of Slot Machine  10 : 4-Option Pickup Bonus Game→Wolfman Bonus: Development Indication) 
     When the development to the Franken BONUS has been internally confirmed, the development indication occurs at the probability of 50%. In the development indication, when the occurrence of the indication is confirmed, a process  1  where in which one of five games an effect is conducted is randomly determined and a process  2  where an effect (the wolfman is chased by the Franken mum) is executed in upper parts of the reels while the reels are rotating in the game determined in the process  1  are conducted. In the development indication, the data tables shown in  FIGS. 126A to 126C  are referred to, for example. 
     More specifically, in case of the first five times of the free game before the re-trigger, if the development to the Franken BONUS is achieved in the free game of one time, an effect development table shown in  FIG. 126A  is referred to. Then “Without Effect” or “With Effect” is randomly selected. The random selection probabilities of “Without Effect” and “With Effect” are both 50%. When “Without Effect” is selected, no development indication effect is executed. That is to say, the development indication effect may not be executed even if the development to the Franken BONUS is to be conducted. As such, the development from the Wolfman BONUS to the Franken BONUS may occur even if no development indication is executed. 
     On the other hand, when “With Effect” is selected, an effect occurring game time table of  FIG. 126C  is referred to in order to determine in which time of the free game the development indication effect is to be executed. According to the effect occurring game time table, one of “first and sixth times”, “second and seventh times”, “third and eighth times”, “fourth and ninth times”, and “fifth and tenth times” is randomly selectable. The random selection probability of “first and sixth times” is 20.00%, the random selection probability of “second and seventh times” is 10.00%, the random selection probability of “third and eighth times” is 10.00%, the random selection probability of “fourth and ninth times” is 20.00%, and the random selection probability of “fifth and tenth times” is 40.00%. For example, when “third and eighth times” is selected, the development indication effect is executed in the third time of the free game. When the re-trigger occurs, the development indication effect is executed in the eighth time of the free game. 
     In the first five times of the free game, if the development to the Franken BONUS is not achieved in any time of the free game, an effect occurrence table of  FIG. 126B  is referred to. Then “Without Effect” or “With Effect” is randomly selected. The random selection probabilities of “Without Effect” and “With Effect” are 87.5% and 12.5%, respectively. In other words, the probability of “Without Effect” is higher than the probability of “With Effect”. When “Without Effect” is selected, no development indication effect is executed. 
     On the other hand, when “With Effect” is selected, an effect occurring game time table of  FIG. 126C  is referred to in order to determine in which time of the free game the development indication effect is to be executed. In such a case, because the development indication effect is executed even if the development does not occur, false information is provided to the player. 
     (Operations of Slot Machine  10 : 4-Option Pickup Bonus Game→Vampire Bonus) 
     When the vampire is selected in the 4-option pickup bonus game, a Vampire BONUS occurs. The Vampire BONUS is a 6-option pickup bonus game in which 6 options appear on the screen (the layout of the options is randomly determined each time). Once the selection finishes, 6 options appear again (the layout of the options is randomly determined each time). It is noted that this arrangement is different from the selection from the remaining five options. The bonus ends either when END is selected or when the selection is serially done eight times. At the end of the bonus, the development to the Franken BONUS is always conducted. All of the six options involve the credit payout, including the END. 
     To be more specific, the Vampire BONUS is performed by executing the processes  1  to  6 . In the process  1 , six selectable icons (window icons) are displayed. In the process  2 , the text “HOW MANY TIMES GAME IS PLAYED” is displayed on the screen. For example, (THE 1st GAME). Furthermore, the texts explaining the game rules and requesting the selection of an icon are displayed. In the process  3 , the cursor for the selection of the control panel is hidden until the BET button on the control panel  30  is pressed. On the control panel  30 , only the 1-BET button  34  and four neighboring buttons are in the on state. The cursor appears at the upper left corner as the BET button is pressed, and the SPIN button is turned on and the determination becomes available. The cursor for the selection is always hidden at the start of the selection. 
     When in the process  4  the selection by the player is conducted, a result of the selected icon is displayed and then a result of a non-selected icon is displayed (in gray). The results are displayed for four seconds at least. When the WIN increment is not shorter than four seconds, the results are displayed until the increment finishes. The display of the results may be skipped by pressing SPIN buttons. The obtained credits are added to the bonus win meter. The processes  1  to  4  are repeated until either the END is selected in the process  5  or the selection is succeeded eight times. When the bonus ends in the process  6 , a result screen is displayed. In case of continue, the “HOW MANY TIMES GAME IS PLAYED” is updated, and the selection by the player is waited for again.

Furthermore, the selection screen displays the continue and the end conditions of the game, the payout which is four digits at the maximum, and the explanations on the button operations. 
     As a selection is made through the selection screen, the shifting to the selection screen stage occurs. That is to say, as shown in  FIG. 130 , when in the selection screen the credit payout is selected less than eight times, the navigation text “Select a WINDOW” requesting the selection disappears. The window opens and the selection result is displayed. The vampire takes an action in accordance with the result. After one second, non-selected icons are displayed in gray.

     (Operations of Slot Machine  10 : Franken Bonus→Mini Game  2 ) 
     The following will describe a case where the mini game  2  is selected in the 29-option game of the Franken BONUS. In the mini game  2  a meter (voltage meter) appears in the screen. The meter has four levels. As the level increases as Lv 1 →Lv 2 →Lv 3 →Lv 4 , the payout is changed in accordance with the achieved level. As the player presses the SPIN button, the level of the meter is increased. This, however, does not influence on the payout. After the end of the bonus, the 29-option game is continued. 
     In the mini game  2 , the following processes  1  to  5  are executed. In the process  1 , a 4-stage meter (voltage meter) is displayed in the screen. In the process  2 , an effect of the voltage meter is executed in accordance with the internally-determined payout. That is, an effect of waking up the Franken sleeping on the electric chair is conducted.

These start declaration texts are continuously displayed in animation. 
     Subsequently, as shown in  FIG. 159 , a meter effect screen having a 4-stage meter is displayed. The 4-stage meter has a fan-shaped analog display region. This analog display region is arranged to indicate the state of progress from left to right in the figure, in analog. The analog display region is divided into four areas. These areas are, from left to right in the figure, a first area, a second area, a third area, and a fourth area. At each of the upper ends of the first to fourth areas, the number of payout is displayed. In addition to the above, on the upper edge side of the analog display region, a pointing unit is provided to indicate the state of progress. The pointing unit is arranged to be movable along the upper edge. Furthermore, on the left edge and right edge sides of the analog display region, “MIN” are “MAX” are displayed, respectively. 
     The operation of the meter effect screen with the arrangement above will be described. As shown in  FIG. 160 , the pointing unit of the voltage meter moves from the MIN to the border between Lv 1  and Lv 2 . A teasing effect is executed around the border so that it is indeterminate whether the pointing unit goes to Lv 2  or remains in Lv 1 . On the screen, an electric current corresponding to the voltage meter is applied to the Franken mum sleeping on the electric chair. When the pointing unit remains in Lv 1 , The voltage meter stops in the Lv 1 . The result corresponding to Lv 1  is displayed. The Franken mum sleeping on the electric chair wakes up. The number of payout is added to the bonus win meter in an increment manner. Then the 29-option game comes back. 
     On the other hand, when the pointing unit does not remain in Lv 1 , as shown in  FIG. 161 , the voltage meter moves from Lv 1  to the border between Lv 2  and Lv 3 . A teasing effect is executed around the border so that it is indeterminate whether the pointing unit goes to Lv 3  or remains in Lv 2 . On the screen, an electric current corresponding to the voltage meter is applied to the Franken mum sleeping on the electric chair. When the pointing unit remains in Lv 2 , the voltage meter stops in Lv 2 . The result corresponding to Lv 2  is displayed. The Franken mum sleeping on the electric chair wakes up. The number of payout is added to the bonus win meter in an increment manner. Then the 29-option game comes back. 
     On the other hand, when the pointing unit does not remain in Lv 2 , as shown in  FIG. 162 , the voltage meter moves from Lv 2  to the border between Lv 3  and Lv 4 . A teasing effect is executed around the border so that it is indeterminate whether the pointing unit goes to Lv 4  or remains in Lv 3 . On the screen, an electric current corresponding to the voltage meter is applied to the Franken mum sleeping on the electric chair. When the pointing unit remains in Lv 3 , the voltage meter stops in Lv 3 . The result corresponding to Lv 3  is displayed. The Franken mum sleeping on the electric chair wakes up. The number of payout is added to the bonus win meter in an increment manner. Then the 29-option game comes back. When the pointing unit remains in Lv 4 , as shown in  FIG. 163 , the voltage meter moves from Lv 3  to MAX. The result corresponding to Lv 4  is displayed. The Franken mum sleeping on the electric chair wakes up. The number of payout is added to the bonus win meter in an increment manner. Then the 29-option game comes back. 
     When the voltage meter operates as above, it is possible to change the operation of the voltage meter by making an input to the spin button  46 . As the spin button is pressed during a bonus, the voltage meter is increased. This, however, does not influence on the WIN credit which has internally been determined at the start of the bonus. 
     Details of how the voltage meter increases will be given. The voltage meter automatically increases over time, and also increases in response to an input from the player. The upper limit of the increase in the voltage meter is determined in advance for each phase. There are two patterns of the increase in the voltage meter. In a pattern  1 , no input is made to the button and the meter automatically increases over predetermined time. In a pattern  2 , the meter increases when the input to the button is made for a predetermined number of times. When an input to the button is made in the state of the pattern  1 , the time is reset. The predetermined time and the predetermined number of times of the input are not uniform in the pattern  2 . Basically, the time and the number increase at the each teasing point and as the meter gets close to Lv 4 . 
     The upper limit of the increase in the voltage meter will be detailed. As shown in  FIG. 164 , assume that the first area, the second area, the third area, and the fourth area of the voltage meter are provided along a linear line. In this case, the upper limit exists around the right edge part of each area, and the teasing point exists around this upper limit. The pattern of the increase in the voltage meter is divided into phases  1  to  4 . As shown in  FIG. 165 , the phase  1  includes an increase operation  1  in which the analog indicated amount reaches the middle of the second area and an increase operation  2  in which the analog indicated amount remains in the first area. One of these phases is randomly selected. When the payout is determined in Lv 1 , if the increase is being performed in the increase operation  1 , the payout is determined after the analog indicated amount in the second area disappears. On the other hand, when the increase is being performed in the increase operation  2 , the payout is immediately determined. In the meanwhile, when the payout is not determined, the process shifts to the phase  2 . 
     As shown in  FIG. 166 , the phase  2  includes an increase operation  1  in which the analog indicated amount reaches the middle of the third area and an increase operation  2  in which the analog indicated amount remains in the second area. One of these phases is randomly selected. When the payout is determined in Lv 2 , if the increase is being performed in the increase operation  1 , the payout is determined after the analog indicated amount in the third area disappears. On the other hand, when the increase is being performed in the increase operation  2 , the payout is immediately determined. In the meanwhile, when the payout is not determined, the process shifts to the phase  3 . 
     As shown in  FIG. 167 , the phase  3  includes an increase operation  1  in which the analog indicated amount reaches the middle of the fourth area and an increase operation  2  in which the analog indicated amount remains in the third area. One of these phases is randomly selected. When the payout is determined in Lv 3 , if the increase is being performed in the increase operation  1 , the payout is determined after the analog indicated amount in the fourth area disappears. On the other hand, when the increase is being performed in the increase operation  3 , the payout is immediately determined. In the meanwhile, when the payout is not determined, the process shifts to the phase  4 . As shown in  FIG. 168 , in the phase  4 , the analog indicated amount is continuously increased from the last state in the phase  3  to the fourth area.

In addition to the above, the addition to the credit meter is executed (F 257 ). Thereafter, after a predetermined time such as two seconds elapses, the screen of the normal game comes back (F 258 ). On the other hand, when “LOSE” appears in Gamble (F 259 ), a LOSE screen is displayed (F 260 ). Thereafter, after a predetermined time such as two seconds elapses, the screen of the normal game comes back (F 261 ). 
     The roles of the buttons in the progress of the gamble game will be described. In the cashout button  32 , GAMBLE ON corresponds to “TAKE WIN” and GAMBLE OFF corresponds to “TAKE WIN”. In the gamble button  44 , GAMBLE ON corresponds to “Gamble Start” and GAMBLE OFF corresponds to “-”. IN the maximum BET button  45 , GAMBLE ON corresponds to “Invalidated” and GAMBLE OFF corresponds to “Gamble Start”. In the spin button  46 , GAMBLE ON corresponds to “To Normal Game” and GAMBLE OFF corresponds to “To Normal Game”. 
     As shown in  FIG. 190 , the “RESIDUAL GAMBLE” screen has a card display area, a navigation area, and a meter area. In the card area is displayed a card image. The entirety of the card area has a touch sensor function. On the navigation area, various navigation texts are displayed. 
     The limit of the value winnable in Gamble is set in the AUDIT. The maximum number of times of Gamble is also set in the AUDIT. For example, the maximum number of times is set at five and the number of times of Gamble is set so as to be five or lower. Whether the touch panel can be used is switchable in some countries. 
     As shown in  FIG. 191 , when the shifting to the gamble game occurs, the message “PLAY ON, GAMBLE or TAKE WIN RED” disappears. Immediately after the clearance of the RAM, the card history is empty until the gamble game is played. A message “SELECT RED OR BLACK OR TAKE WIN” is displayed. In the gamble screen, a heart-shaped red button and a spade-shaped black button are turned on and a TAKE WIN button at the center is turned on. The other buttons are turned off. 
     Subsequently, as shown in  FIG. 192 , the amount bet on “GAMBLE AMOUNT” is displayed. Then one of the heart-shaped red button, the spade-shaped black button, and the TAKE WIN button at the center on the gamble screen is selected. When the TAKE WIN button is selected, the amount of WIN is added to the credits at once and the idle state comes back. 
     In case of Miss in Gamble, as shown in  FIG. 193 , non-selected options are darkened. At the left edge of the gamble history field, the card history is displayed at once. The preceding card history moves right. The trace of the movement is not illustrated in animation, and hence the history is rewritten at once. The central card result is displayed at once. At this stage, there are no changes in the win meter and the gamble meter. Sound indicating hard luck is output and the shifting to the normal game occurs after several seconds. 
     In case of Success in Gamble, as shown in  FIG. 194 , non-selected options are darkened. At the left edge of the gamble history field, the card history is displayed at once. The preceding card history moves right. The trace of the movement is not illustrated in animation, and hence the history is rewritten at once. On the central card, a normal card and a card with a WIN text are alternately displayed at intervals of one frame, and success sound is output for a predetermined time. To the win meter, the value increase as a result of Gamble is added at once. When the player plays the gamble game until reaching the maximum number to times, the value won is added to the credits at once and the idle state comes back. As shown in  FIG. 194 , when the player has not played the gamble game until reaching the maximum number to times, a card is turned inside out and the gamble game is continued. 
     While in the present embodiment the number of paylines L is 30, the number of paylines is not limited; the number of paylines may be a predetermined number such as 25. 
     Although in the present embodiment the bonus winning is a case where three or more trigger symbols are rearranged, the disclosure is not limited to this arrangement. For example, the bonus winning may indicate the state in which a predetermined time elapses after the end of the previous bonus game. 
     In addition to the above, according to the present embodiment, the free game is arranged so that, symbols are variably displayed in the display block  28  and the variation is stopped, and a payout amount is determined in accordance with the symbols having stopped or a combination thereof (i.e., a game usually run on a slot machine). The free game of the disclosure, however, is not limited to the arrangement above. The free game may be a game different from a slot game. For example, card games such as Poker, shooting games, fighting games may be run. As a result of the free game, a game medium may be paid out or may not be paid out. 
     In addition to the above, when a free game is run based on the fact that the number of times of the normal game counted in the insurance mode reaches a predetermined number and then the number of times of the normal game counted in the insurance mode reaches the predetermined number again, a free game different from the previous free game may be run. The free game of the present invention may be designed in various ways, as long as the game does not presuppose the betting of a game medium.
