  However, with the proposed ball and ball game machine, the jackpot game is only a special jackpot game with a certain probability. There was a problem that it could not be said that it was raised. However, if a special game mode in which a special big hit game is likely to occur, for example, is provided in order to utilize the special big hit game, a new problem that the control of the gaming machine becomes complicated is caused.

  The present invention has been made to solve the above-described problems of conventional ball game machines, and is not limited to a special big hit game that opens and closes a big winning opening even during a round game, but a big hit in a plurality of modes. An object of the present invention is to provide a ball game machine that can sufficiently enhance the interest of a player without complicating the control of the game machine by utilizing the fact that the game can be executed.

In order to solve at least a part of the above-described problems, the bullet ball game machine of the present invention employs the following configuration. That is,
A ball game in which a game ball is fired on a game board surface provided with a plurality of entrances, and when a game ball enters one of the entrances, a predetermined number of game balls are paid out. In the machine
A fixed first start opening into which a game ball can enter ;
And playing ball ball entrance difficult the normal state, a second start hole that can place cut into a ball entrance easy open state playing ball than the normal state,
A second start port opening means for opening the second start port until a predetermined opening time elapses when a predetermined condition is established during the game;
Game ball and the ball entrance non-closed state, the game ball is configured to be able to instead cut into a ball entrance can be open state, and usually at the time of variable prize hole that has become a closed state,
A large per game execution means the variable winning port open state and to Lula und game to run a jackpot gaming that is repeated a predetermined number of times,
A normal mode in which the variable prize opening is held in an open state during the round game by performing a lottery when a game ball enters the first start port or the second start port, and the round game A special mode that repeats the open state and the closed state of the variable winning opening, and a jackpot game lottery means for determining in which mode the jackpot game is executed ,
The second start hole opening means is in a predetermined period after completion of the jackpot gaming, set the opening time of the second start hole to a longer time than usual,
The jackpot game lottery means is:
A likely first drawing mode it is elected the jackpot gaming of the normal mode than jackpot gaming of the special aspect, a likely second lottery aspect won the jackpot gaming of the special embodiment as compared with the first drawing mode Remember,
A lottery is performed in the first lottery mode for entering the first starting port, and a lottery is performed in the second lottery mode for entering the second starting port. .

Such a ball game machine of the present invention is equipped with two types of start ports, a fixed first start port and a second start port that can be switched between a normal state and an open state. Even if a game ball enters, a lottery is performed. When the lottery is won, the big hit game is started, and after the big hit game is finished, the opening time of the second start port is set to a longer time than usual. Here, when a game ball enters the first start port, the lottery is performed in the first lottery mode, and when the game ball enters the second start port, the lottery is performed in the second lottery mode. And, in the first lottery mode, the big hit game of the normal mode (that is, the big hit game of the mode in which the variable winning opening is maintained in the open state during the round game) is more likely to occur than the special type of big hit game, In the second lottery mode, compared to the first lottery mode , a special mode jackpot game (that is, a jackpot game in which the variable winning opening repeats an open state and a closed state during a round game) is more likely to occur. Is set to

With such a configuration, once the big hit game is started, the opening time of the second start port is set longer than usual after the big hit game is finished, so the second start is made more than the first start port. It becomes easier for game balls to enter the mouth. As a result, the lottery is performed in the second lottery aspect, the jackpot gaming special aspect is likely to occur as compared with the first drawing mode. On the other hand, after the opening time of the second start opening returns to the normal opening time before the occurrence of the big hit game or after the end of the big hit game, As a result, the lottery is performed in the first lottery mode, and the occurrence frequency of the big hit game in the normal mode is increased. After all, for the player, after the jackpot occurs, the variable winning openings have special periods likely jackpot gaming occurs special embodiment is provided to repeat opening and closing, jackpot gaming normal mode is likely to occur in other cases It feels like As a result, it is possible to fully enhance the interest of the player with respect to the game by fully utilizing the special hit game. Of course, since a special period is not actually provided by a control method, the control of the gaming machine is not complicated at all.

  In the ball game machine of the present invention, the following may be performed. First, the opening of the second start port is performed as follows. That is, when a specific condition is established during the game, a lottery is performed as to whether or not the second start port is in an open state, and the second start port is set in an open state when the lottery result is a win. In a predetermined period after the end of the big hit game, the time required for the lottery may be shorter than usual.

In this way, after the big hit game is over, the time required for the lottery of the second start port is shortened, so that the opening frequency of the second start port is increased and the opening time is also lengthened. As a result, the opening / closing operation of the second start port is easily noticed by the player, and the game ball can easily enter the second start port. As described above, for the ball entering the second starting port, lottery is performed in the second lottery mode, and when a big hit game occurs, the variable prize opening is repeatedly opened and closed during the round game, Associating the operation of the second starting opening and closing repeatedly after the big hit game with the operation of the variable winning opening repeatedly opening and closing during the big hit game, and receiving an impression as if the game state has shifted to a different gaming state. Become. As a result, it is possible to further effectively utilize the fact that the special mode jackpot game can be executed, and to greatly increase the interest of the player.

  In addition, in the above-described bullet ball game machine of the present invention, hold information indicating that a game ball has entered the first start port or the second start port can be stored up to a predetermined number corresponding to each start port. In addition, a lottery may be performed based on the stored hold information. If hold information is stored for both the first start port and the second start port, the lottery based on the hold information for the second start port may be preferentially performed.

As described above, the lottery based on the hold information of the first start port is performed in the first lottery mode in which the big hit game of the normal mode is likely to occur, and the lottery based on the hold information of the second start port is the big hit of the special mode. It is performed in the second lottery mode in which games are likely to occur. Therefore, when both the lottery based on the hold information of the first start port and the lottery based on the hold information of the second start port are possible, the lottery based on the hold information of the second start port is given priority. As a result, it is easy to generate special- hit big hit games continuously, and as a result, it is possible to give the player a stronger impression as if the game state has changed from the normal state. Can be further increased.

Further, in the above-described bullet ball game machine of the present invention, the following may be performed. First, a plurality of types of lottery tables in which the mode of the jackpot game is set for each random value indicating whether the mode is a normal mode or a special mode are stored. Then, when a game ball enters the first start port or the second start port, a random number value is acquired, and then a lottery table used for lottery is selected from a plurality of types of stored lottery tables, and then acquired. Based on the random number value and the selected lottery table, the mode of the jackpot game is determined. As the lottery table, a first lottery table is towards the jackpot gaming normal manner than jackpot gaming special aspects associated with many random numbers, jackpot Yu special aspect than the first lottery table A second lottery table in which the technique is associated with a large number of random numbers, and a third lottery table in which a special feature jackpot game is associated with more random numbers than in the second lottery table; deep. When the lottery is performed in the first lottery mode, the first lottery table is selected. When the lottery is performed in the second lottery mode and the opening time of the second start port is set to a normal predetermined time, the second lottery table is selected. Furthermore, when the lottery is performed in the second lottery mode and the opening time of the second start port is set to be longer than usual, the third lottery table may be selected.

In this way, when a game ball enters the second start port while the opening time of the second start port is set to be longer than usual, a lottery is performed using the third lottery table. Therefore, special mode jackpot games occur at a higher frequency. As a result, it is possible to give the player an even stronger impression as if the player has transitioned to a special gaming state and to excite the player's interest.

Further, in the ball game machine of the present invention having the lottery table described above, after the jackpot game is over, the probability of winning the jackpot game is higher than the normal state (probability variation state, hereinafter “probability variation state”). And the following lottery table may be used. That is, the lottery table, whether aspects of the jackpot gaming is either normal mode or special mode, which is set whether to probability variation state after completion of the jackpot gaming if and only if become probability variation state special aspect Is set to generate a big hit game. The third lottery table may be a table in which the jackpot game mode is changed to a special mode in the second lottery table, although the jackpot game is in the normal mode but the normal mode is changed. good.

In this way, the probability of jackpot game is increased by setting the probability change state, and the jackpot game is in a special mode with high probability, so that the player has the impression that it has switched to a special game state after the first hit. It is possible to make a strong impression. It should be noted that the special mode jackpot game is generated only when the state is switched to the probability variation state. Therefore, when the third selection table, the winning probability of where the effect that Waru conversion cut after large per game normal mode to the non-probability variation state is set lower, to increase the probability of winning the jackpot gaming special embodiment, the Compared with the lottery table 2, the occurrence frequency of the probability variation state is increased, and the number of game balls to be paid out may be increased. However, if the change to the probability change state after the big hit game in the normal mode is changed to change to the probability change state after the big hit game in the special mode, there is no effect on the occurrence frequency of the probability change state. It is possible to easily increase the occurrence frequency of the special mode jackpot game without giving a bonus.

In the present embodiment, the display state shown in FIG. 7C, that is, the state in which the left normal symbol display unit 29a is turned off and the right normal symbol display unit 29b is lit is set for the normal symbol. Yes.

  If the game ball passes through the normal symbol operation gates 36 and 37 during the normal symbol variation display, the passing of the game ball is stored as the number of holdings, and the current normal symbol variation display is terminated. Display is performed. Up to four normal symbol holds can be stored, and the number of stored normal symbols is stored in the normal symbol hold display unit 29c (FIG. 3 (a) provided in the first symbol display device 28. ))).

  As described above with reference to FIG. 3A, the first symbol display device 28 is provided with the first special symbol display unit 30 so that the first special symbol can be variably displayed. Further, as shown in FIG. 3B, the second special symbol display unit 33 provided in the second symbol display device 32 can display the second special symbol in a variable manner. Of these, the first special symbol corresponds to the first start port 17a, the second special symbol corresponds to the second start port 17b, and the first special symbol or the second special symbol corresponds to the corresponding start port. When a game ball enters, the variable display is started. As described above with reference to FIG. 5, in the state where the second start port 17b is not open (normal state), almost no game ball enters the second start port 17b. In this state, the game ball Mainly enters the first starting port 17a and the first special symbol is displayed in a variable manner. Conversely, when the second starting port 17b is in the open state, the game ball is started second than the first starting port 17a. Since it becomes easy to enter the mouth 17b, the second special symbol is mainly displayed in a variable manner. Further, as described above, both the first special symbol display unit 30 and the second special symbol display unit 33 are configured by 7-segment LEDs, and therefore the first special symbol and the second special symbol are in the same manner. Display fluctuation.

  FIG. 8 is an explanatory diagram conceptually showing a state in which the first special symbol or the second special symbol is variably displayed. The first special symbol and the second special symbol have the same variation, and therefore, here, they are simply referred to as a special symbol without distinguishing between the two. During the special symbol variation display, the symbol “A” or “Y” is displayed on the left special symbol display unit 30a, and the comma “.” Is displayed on the right special symbol display unit 30b. Further, “A” and “Y” in the left special symbol display unit 30a and the comma “.” In the right special symbol display unit 30b can take three states of red, orange, and green. In the special symbol display unit 30 of the present embodiment, these display states can be combined to display 12 types of states shown in FIG. In the figure, the 7-segment LED or the comma portion that is finely hatched indicates that it is lit in a red state. In addition, a little rough hatching indicates that it is lit and displayed in an orange state, and a rough hatching indicates that it is lit and displayed in a green state. . When the special symbol variation display is started, these 12 types of display states are displayed in such a manner that they are switched one after another at a high speed.

  If the symbol displayed as “-” is “-”, the special symbol is removed, but if any other combination of symbols is stopped, the special symbol is a hit and the gaming state is advantageous to the player. A special game state (so-called jackpot game) is started. That is, as combinations of symbols on which the special symbol is won, there are 10 types of combinations excluding “−” from the 12 types of symbols shown in FIG. In addition, the special game state of the present embodiment is configured such that a round game in which the big winning opening 31d is opened by the operation of the big winning device 31 is repeated a plurality of times. Since the big winning opening 31d is greatly opened, a game ball enters with a high probability. As a result, the player can acquire many prize balls while a predetermined number of rounds are repeated.

  If a game ball enters the first start port 17a while either the first special symbol or the second special symbol is variably displayed, the number of the game balls that enter the game will be the number of reserved first ball symbols. The accumulated display of the first special symbol is performed after the accumulated display of the current special symbol is completed. Similarly, if a game ball enters the second start port 17b while either the first special symbol or the second special symbol is variably displayed, the number of the game balls received is the number of the second special symbol held. As stored. Any of these first special symbol or second special symbol hold can be stored up to a maximum of four, and the number of reserved hold is the first symbol display device 28 for the first special symbol hold. The first special symbol hold display unit 30c (see FIG. 3A), and the second special symbol hold display unit 33c (FIG. 3B) of the second symbol display device 32 for holding the second special symbol. Displayed).

  In addition, among the 10 types of combinations that the special symbol shown in FIG. 8 is a winning combination, the 5 types of combinations surrounded by a solid line are so-called “probable variation per symbol (or special probability variation per symbol)”, and the variation If the displayed 1st special symbol or 2nd special symbol is stopped by any of these probable winning symbol combinations, it will stop at the winning symbol from the end of the special game until the start of the next special game. The probability of being displayed is higher than the normal state. In this way, a gaming state in which the probability of being stopped and displayed with a winning symbol is high is called a probability variation gaming state (or simply a probability variation state).

  Furthermore, among the 10 types of combinations that the special symbol shown in FIG. 8 is a winning combination, the five types of combinations surrounded by a broken line are so-called “normal winning symbols”, and the first special symbol displayed in a variable manner. Alternatively, when the second special symbol stops at any one of the combinations of these normal winning symbols, the special symbol is variably displayed a predetermined number of times (in this embodiment, 100 times) after the special game ends, or the next special game Until the state is started, the special symbol variation time is shortened and the opening time of the second starting port 17b is lengthened. Such a gaming state is referred to as a variable time shortening state (or a short time state). In the gaming machine 1 of the present embodiment, such a time-saving function is activated not only when the stop display is performed with the normal winning symbol but also when the stop display is performed with the positive variation symbol. Eventually, if the first special symbol or the second special symbol is stopped and displayed in any of the ten types of winning symbols shown in FIG. 8, the time-saving function is always activated after the special gaming state is ended. .

  Further, in the gaming machine 1 of this embodiment, one of the five types of probability variation symbols is set to “special probability variation symbol”. When the special symbol is stopped and displayed with the “special probability variation winning symbol”, the special game (big hit game) is executed in a special manner to be described later.

  In accordance with the above-described change stop display of the special symbol, the change display device 27 performs various effects using the effect symbols. FIG. 9 is an explanatory diagram illustrating an aspect of the effect performed by the variable display device 27. As described above with reference to FIG. 4, the three design symbols 27 a, 27 b, and 27 c are displayed on the liquid crystal display screen constituting the variable display device 27. When the variation display of the special symbol is started in either the first symbol display device 28 or the second symbol display device 32 described above, these three design symbols 27a, 27b, and 27c are simultaneously displayed on the variation display device 27. Start the variable display. In the present embodiment, a design is prepared by designing nine numbers from “1” to “9” as a design.

  FIG. 9A conceptually shows how the three design symbols 27a, 27b, and 27c are variably displayed at the same time. When a predetermined time elapses after the variable display is started, the left design symbol 27a is first stopped and displayed in any one of “1” to “9”, and then the right design symbol 27c is stopped and displayed. The medium design symbol 27b is stopped and displayed. The combination of the three design symbols 27a, 27b, and 27c that are stopped and displayed on the variable display device 27 is a special symbol (first special symbol) that is stopped and displayed on the first symbol display device 28 or the second symbol display device 32 described above. Or it is comprised so that it may link with the combination of a 2nd special symbol). For example, when the first special symbol or the second special symbol stops at the winning symbol, the three design symbols 27a, 27b, and 27c of the variable display device 27 are stopped and displayed with the same symbol. In particular, when the first special symbol or the second special symbol stops at the above-described probability variation symbol, the three design symbols 27a, 27b, and 27c of the variable display device 27 are stopped and displayed at the same symbol representing an odd number. . On the other hand, when the first special symbol or the second special symbol comes off and stops at the symbol, the three design symbols 27a, 27b, and 27c are stopped and displayed in an arbitrary combination that does not align with the same symbol.

  As described above, the special symbols displayed on the first symbol display device 28 or the second symbol display device 32 and the three design symbols 27a, 27b, and 27c displayed on the variable display device 27 correspond to each other. When the changing first special symbol or the second special symbol is stopped and displayed, the three design symbols 27a, 27b and 27c are also stopped and displayed. Moreover, as shown in FIG. 2, the variable display device 27 is provided at a position that is more visible than the first symbol display device 28 and the second symbol display device 32, and the display screen is large and the display contents can be understood. Since it is easy, a player usually plays a game while looking at the screen of the variable display device 27. Therefore, when the left design symbol 27a initially stopped and displayed on the display screen of the variable display device 27 and the right design symbol 27c subsequently stopped and displayed are the same symbol, the stop design is finally displayed. The player pays attention to the change in the design so that the medium design design 27b may stop at the same design and enter a so-called jackpot gaming state. In this way, the effect of variably displaying the last design with the two design symbols stopped at the same design is called a reach effect, and it is possible to enhance the interest of the player by performing the reach effect. It has become.

C. Game machine control contents:
Below, in order to implement | achieve the game mentioned above, the control content which the game machine 1 of a present Example is performing is demonstrated in detail.

C-1. Game control processing:
FIG. 10 is a flowchart showing a rough flow of a game control process performed by the CPU 201 mounted on the main control board 200 to control the progress of the game. As shown in the figure, in the game control process, each process such as a prize ball-related process, a normal symbol game process, a normal electric accessory stop process, a special symbol game process, and a special electric accessory game process is repeatedly executed. . The time required for one round of processing is about 4 msec. Therefore, these various types of processing are repeatedly executed about every 4 msec. Then, during these processes, various commands are transmitted from the main control board 200 to the various control boards including the sub control board 220. By doing so, the game of the entire gaming machine 1 progresses, and the sub control board 220 controls the effect according to the progress of the game. The game control process performed by the CPU 201 mounted on the main control board 200 will be described below according to the flowchart.

  When starting the game control process, the CPU 201 mounted on the main control board 200 performs a process (pay ball related process) for paying out a game ball as a prize ball (S50). In this process, among the various switches connected to the main control board 200, the switches related to the winning of the game ball (the first starting port switch 17s, the second starting port switch 17t, the big winning port switch 31s, etc.) It is detected whether or not a game ball has entered. When a game ball is detected, the number of prize balls to be paid out is calculated, and then a process for outputting a prize ball number designation command to the payout control board 240 is performed. When the payout control board 240 receives the award ball number designation command output from the main control board 200, the payout control board 240 interprets the content of the command, and outputs a drive signal to the payout motor 109m mounted on the payout device 109 according to the result. Thus, a process of actually paying out the prize ball is performed.

  When the CPU 201 of the main control board 200 performs the process related to the prize ball (S50), this time, it is determined whether or not the normal symbol game process is performed, that is, whether or not the normal symbol variation stop display is performed ( S100). Such a determination is made by detecting whether or not the ordinary electric accessory is operating, in other words, whether or not the second starting port 17b is being opened. If the normal electric accessory is not operating, it is determined that the normal symbol game process is performed (S100: yes), and if the normal electric accessory is operating, it is determined that the normal symbol game process is not performed (S100: no). If it is determined that the normal symbol game process is to be performed (S100: yes), the normal symbol game process described below is performed (S150). On the other hand, when it is determined not to perform the normal symbol game process (S100: no), the normal symbol game process (S150) is skipped.

  In the normal symbol game process (S150), the following processes are mainly performed. First, it is determined whether or not the number of held ordinary symbols is present (whether it is “0”). If the number of retained symbols is present, whether or not the ordinary symbol is present is determined. Here, the reserved number of normal symbols is set when the game ball passes through the normal symbol operating gates 36 and 37, and in this embodiment, the upper limit value of the reserved number is set to “4”. Then, based on the determination result of the normal symbol, it is determined whether the normal symbol is to be stopped and displayed with the winning symbol (see FIG. 7C) or to be stopped with any other off symbol. Next, after setting the normal symbol fluctuation display time, the normal symbol fluctuation display is started. When the variable display time elapses, the normal symbol is stopped and displayed with the determined symbol. At this time, when the hit symbol of the normal symbol is stopped and displayed, the operation of the normal electric accessory is started. When the ordinary electric accessory is operated in this way, the pair of blade pieces 17w provided at the second starting port 17b rotate outward, and the second starting port 17b is in an open state.

  The lottery for determining whether or not to open the second start port 17b and the operation for opening the second start port 17b are performed while the CPU 201 of the main control board 200 executes the above-described normal symbol game process. Yes. Therefore, the CPU 201 mounted on the main control board 200 of the present embodiment corresponds to the “opening lottery means” and the “second starting port opening means” in the present invention.

  When the normal symbol game process is completed as described above, it is determined whether or not the normal electric accessory is operating (S190). If it is in operation (S190: yes), a process for stopping the ordinary electric accessory (ordinary electric accessory stopping process) is performed (S200). On the other hand, when the ordinary electric accessory is not operating (S190: no), it is not necessary to perform the ordinary electric accessory stopping process, and the process is skipped.

  FIG. 11 is a flowchart showing the flow of the ordinary electric accessory stopping process. As shown in the figure, when the ordinary electric accessory stopping process is started, first, it is determined whether or not a predetermined operating time of the ordinary electric accessory has passed (S202). As described above, when the ordinary electric accessory is activated, the second start port 17b is in an open state, but when a predetermined time has elapsed, the pair of blade pieces 17w are again restored to the normal state. Accordingly, in S202, it is determined whether or not the normal electric accessory has reached a preset operation time. If it is determined that the operating time has been reached (S202: yes), after stopping the operation of the ordinary electric accessory (S206), the ordinary electric accessory game process is terminated and the game control shown in FIG. Return to processing. Note that the normal electric accessory operating time (that is, the opening time of the second starting port 17b) is set to about 0.5 seconds in the normal gaming state, but is about 1 when the opening time extending function described later is operated. .Extended to 5 seconds.

  On the other hand, when a prescribed number of game balls enter the second start port 17b, the second start port 17b returns to the normal state even when the opening time has not reached the set time. Correspondingly, if the operating time of the ordinary electric accessory has not reached the predetermined time (S202: no), it is determined whether or not a specified number of game balls have entered the ordinary electric accessory ( S204) When it is determined that a specified number of game balls have entered (S204: yes), the operation of the ordinary electric accessory is stopped and the ordinary electric accessory game process shown in FIG. 11 is terminated. On the other hand, when it is determined that there is no prescribed number of balls (S204: no), the ordinary electric game game process shown in FIG. Return to the game control process shown in.

  In the game control process, when returning from the ordinary electric accessory stop process, the process related to the special symbol is started. In this process, after determining whether or not a predetermined condition for performing a special symbol game process described later is satisfied, if the predetermined condition is satisfied, the special symbol game process is started.

  FIG. 12 is a flowchart showing a flow of processing (special symbol game start determination processing) performed to determine whether or not to start the special symbol game processing. In determining whether or not to start the special symbol game process, it is first determined whether or not a game ball has entered the first start port 17a (S252). As described above, the first start port 17a for detecting the entrance of a game ball is provided inside the first start port 17a, and it can be detected that a game ball has entered.

  When the game ball has entered the first start port 17a (S252: yes), it is determined whether or not the number of reserved special symbols has reached the upper limit (“4” in this embodiment). (S254). As described above with reference to FIG. 3 (a), the number of the first special symbol hold is displayed by turning on the LED in the first special symbol hold display unit 30c. If the number of reserved special symbols does not reach the upper limit value (S254: no), the main control board obtains a randomness determination random number for the first special symbol and a symbol determination random number for the first special symbol. The data is stored in the 200 RAM 203. Here, the success / failure determination random number of the first special symbol is a random number used for determining whether or not the first special symbol is displayed on the first special symbol display unit 30 shown in FIG. The symbol determination random number of the first special symbol is a random number for determining the first special symbol to be stopped and displayed on the first special symbol display unit 30 according to the determination result of the first special symbol.

  As described above, when the number of reserved first special symbols has not reached the upper limit “4” (S254: no), various random numbers for the first special symbol are acquired and stored in the RAM 203 (S256). “1” is added to the number of reserved special symbols (S258). On the other hand, when the number of reserved first symbol symbols reaches the upper limit “4” (S254: no), acquisition of various random numbers for the first special symbol is not performed. As a result, up to four random numbers for the first special symbol can be stored.

  On the other hand, when the game ball has not entered the first start port 17a (S252: no), the number of the first special symbol is retained, although the game ball has entered the first start port 17a. If it has reached “4” (S254: yes), it is determined whether or not a game ball has entered the second start port 17b (S262). In addition, when a game ball has entered the first start port 17a and the number of reserved special symbols has not reached the upper limit “4” (S254: no), the first special symbol is used. Are obtained and stored in the RAM 203 (S256), and after adding "1" to the number of reserved first symbols (S258), whether or not a game ball has entered the second start port 17b. Is determined (S262). If a game ball has entered the second start port 17b (S262: yes), it is determined whether or not the number of reserved special symbols has reached the upper limit “4” (S264). If the upper limit value has not been reached (S264: no), the success / failure determination random number and the symbol determination random number for the second special symbol are acquired and stored in the RAM 203 of the main control board 200 (S266), and then the second special symbol “1” is added to the number of holds (S268).

  If it is determined that no game ball has entered the second start port 17b (S262: no), or a game ball has entered the second start port 17b, but the second special symbol is reserved. When it is determined that the number has reached the upper limit “4” (S264: yes), various random numbers for the second special symbol are acquired and stored, or “1” is stored in the number of reserved special symbols. Is skipped, and it is determined whether or not a big hit game is being played (S270). The special symbol game process to be described later is a special game advantageous to the player when the first special symbol or the second special symbol is variably displayed and a predetermined winning symbol is stopped and displayed in any special symbol. This is a process for starting a big hit game. If a big hit game is currently being played, there is no need to repeatedly start a big hit game. Therefore, when the process related to the holding of the first special symbol or the second special symbol is finished, it is determined whether or not the big hit game is being played (S270). If the big hit game is not being taken (S270: no). ), It is determined to start a special symbol game process described later (that is, S250: yes). On the other hand, if the game is already in the big hit game (S270: yes), it is determined that the special symbol game process is not started (that is, S250: no).

  In the present embodiment, the number of reservations of the first special symbol or the second special symbol corresponds to “holding information” in the present invention. The operation for storing the number of suspensions is performed while the CPU 201 mounted on the main control board 200 is performing the special symbol game start determination process shown in FIG. The mounted CPU 201 corresponds to the “hold information storage unit” in the present invention. In addition, when the game ball enters the first start port 17a or the second start port 17b, the CPU 201 mounted on the main control board 200 performs the special symbol game start determination process shown in FIG. Therefore, the CPU 201 mounted on the main control board 200 of this embodiment also corresponds to the “random number acquisition unit” in the present invention.

  As described above, when it is determined that the special symbol game process is to be performed (S250: yes), the special symbol game process described below is performed (S300). On the other hand, if it is determined not to perform the special symbol game process (S250: no), the special symbol game process (S300) is skipped.

C-2. Special design game processing:
13 and 14 are flowcharts showing the flow of the special symbol game process. When the special symbol game process is started, first, it is determined whether either the first special symbol or the second special symbol is changing (S302). As described above with reference to FIG. 3, the gaming machine 1 of the present embodiment is provided with the first symbol display device 28 and the second symbol display device 32, and the first symbol display device 28 has a variation of the first special symbol. The second symbol display device 32 can display the second special symbol in a variable manner.

  When neither the first special symbol nor the second special symbol is changing (S302: no), it is during the time for displaying the first special symbol or the second special symbol as a stop symbol (the special symbol stop display time). Whether or not (S304). That is, in both the first special symbol and the second special symbol, the stop display time for the player to confirm which symbol has been stopped and displayed for a while after the change display of the special symbol is finished. Since it is provided, it is determined whether or not it is during the stop display time. When it is confirmed that neither the first special symbol nor the second special symbol is variably displayed and the stop display time of the special symbol has elapsed (S304: no), the number of reserved second special symbols Is determined to be “0” (S306). That is, as described above, in the gaming machine 1 of the present embodiment, there are two special symbols, the first special symbol and the second special symbol, and the number of holdings corresponding to each is provided. First, the number of reserved special symbols is confirmed. When the number of reserved special symbols is not “0”, in other words, when the number of reserved symbols remains (S306: no), the randomness determination random number for the second special symbol stored in the RAM 203 is included. Then, the random number stored at the earliest timing is read (S308), and the second special symbol related process described later is started (S310).

  On the other hand, if it is determined that the second special symbol hold number is “0” (S306: yes), it is determined whether the first special symbol hold number is “0” (S326), Then, if there is a hold (S326: no), the random number stored at the earliest timing is read out from the randomness determination random numbers for the first special symbol stored in the RAM 203 (S328). Then, the first special symbol related process described later is started (S330). As described above, since the number of reservations of the first special symbol is determined only when the number of reservations of the second special symbol is “0”, whether or not the reservation remains is determined. While the suspension remains, the determination random number for the first special symbol is read and the first special symbol-related process is not performed.

C-2-1. Second special symbol related processing:
FIG. 15 is a flowchart showing the flow of the second special symbol related process. As described above, this process is a process that is started after the success / failure determination random number for the second special symbol is read in the special symbol game process. As shown in the drawing, when the second special symbol related process (S310) is started, first, a determination as to whether or not the second special symbol is true is made (S312).

  FIG. 16 is a flowchart showing a flow of processing for determining whether or not the second special symbol is correct (second special symbol determination processing). As shown in the drawing, when the second special symbol success / failure determination process is started, first, it is determined whether or not the current gaming state is a probable change state (S3120). If it is in the probability variation state (S3120: yes), the probability determination table for probability variation is selected (S3122). If it is not in the probability variation state (S3120: no), the probability determination table for non-probability variation is selected (S3124). . Here, the success / failure determination table is a table in which the determination result of the special symbol is determined in association with the random determination random number of the special symbol, and is stored in advance in the ROM 202 of the main control board 200. In the gaming machine 1 of the present embodiment, the first special symbol and the second special symbol are provided, and the randomness determination random number is stored for each of them. The same table is used for any success / failure random number of the second special symbol. Correspondingly, in this specification, the success / failure determination table of either the first special symbol or the second special symbol is simply referred to as a special symbol's success / failure determination table.

  FIG. 17 is an explanatory view illustrating a special symbol determination table stored in the gaming machine 1 of this embodiment. FIG. 17A shows a non-probability change determination table, and FIG. 17B shows a probability change determination table. As shown in the drawing, in the success / failure determination table, a success / failure determination result of “win” or “out” is set in association with the random determination random number of the first special symbol or the second special symbol. Further, as is clear from the comparison between FIG. 17A and FIG. 17B, the probability variation determination table shown in FIG. 17B is the non-probability variation table shown in FIG. “Win” determination result is set to a larger number of random numbers than the determination table.

  In the second special symbol success / failure determination process shown in FIG. 16, when a corresponding determination table is selected according to whether or not the current gaming state is being probabilistically changed, the special symbol game processing is read first. It is determined whether or not the determination result of the second special symbol is “winning” by referring to the selected determination table based on the determination random number for the second special symbol (S3126). As described above, the success / failure determination table for probability change that is referred to in the probability variation state is more or less a success / failure determination for the number of success / failure determination random numbers than the failure determination table for non-probability variation that is referred to when not in the probability variation state. Since the result is set, the success / failure determination result of “hit” is generated during probability change with higher probability than during non-probability change.

  If it is determined that the result of determining whether or not the second special symbol is successful (S3126: yes), after the symbol determination random number for the second special symbol is read (S3128), the winning symbol of the second special symbol is displayed. Processing to determine is performed (S3130). Here, the symbol determination random number for the second special symbol means that when a game ball enters the second starting port 17b, various special symbols for the second special symbol are included in the special symbol game start determination process shown in FIG. It is a random number that is obtained together with a random number. The winning symbol of the second special symbol is determined by referring to the winning symbol determination table for the second special symbol based on the symbol determining random number for the second special symbol.

  FIG. 18 is an explanatory view exemplifying a hit symbol determination table for the second special symbol that is referred to in order to determine the hit symbol of the second special symbol. As described above, in the second special symbol displayed on the second special symbol display unit 33 of the second symbol display device 32, three symbols of “normal hit symbol”, “probability variable symbol”, and “special probability variable symbol” are provided. Although the winning symbol can be displayed in any manner, the winning symbol determination table for the second special symbol displays any winning symbol in association with the symbol determining random number as illustrated. Is preset. In addition, as described above, in the gaming machine 1 of the present embodiment, the first special symbol is also provided in addition to the second special symbol, and the symbol determination random number is acquired for each of them, and correspondingly, A winning symbol determination table for the second special symbol and a winning symbol determination table for the first special symbol are provided separately.

  In the second special symbol success / failure determination process shown in FIG. 16, when the symbol determination random number for the second special symbol is read, by referring to the hit symbol determination table for the second special symbol shown in FIG. A process of determining a winning symbol of the second special symbol is performed (S3130).

  On the other hand, if the determination result of the second special symbol is “displaced” (S3126: no), the symbol determination random number for the second special symbol is read out as in the case of “win” (S3132). A process of determining an off symbol of the second special symbol is performed (S3134). The process of determining the off symbol is also performed by referring to a off symbol determining table (not shown) in which the out symbol is preset for the second special symbol determining random number. A predetermined out symbol is set for the second special symbol determination random number in the out symbol determination table. Note that, unlike the winning symbol determination table, it is also possible to share the first special symbol table and the second special symbol table for the outlier symbol determination table.

  In the winning symbol determination table shown in FIG. 18, it is set in association with the symbol determining random number whether the big hit mode is “normal hit”, “probable variable hit”, or “special probability variable hit”. Therefore, the winning symbol determination table of this embodiment corresponds to the “lottery table” in the present invention. As will be described later, the hit symbol determination table is provided with a table corresponding to the first special symbol and a table corresponding to the second special symbol, and these tables are stored in the ROM 202 of the main control board 200. Yes. Therefore, the ROM 202 mounted on the main control board 200 of this embodiment corresponds to the “lottery table storage unit” in the present invention. The process of determining the winning symbol using the winning symbol determination table corresponding to each of the first special symbol or the second special symbol is performed by the CPU 201 of the main control board 200 in the special symbol game processing shown in FIG. The second special symbol-related processing (S310) or the first special symbol-related processing (S330) described later is switched. Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “lottery table selection means” and the “hit game mode determination means” in the present invention.

  As described above, in the determination process for the second special symbol shown in FIG. 16, whether or not the second special symbol is determined based on the previously read second special symbol determination random number is determined. Depending on the result, a process of determining a winning symbol or a missing symbol of the second special symbol is performed (S3130 or S3134). When the winning symbol or the off symbol is determined, the second special symbol success / failure determination process is terminated, and the process returns to the second special symbol game process shown in FIG.

  As shown in FIG. 15, in the second special symbol game process, when returning from the second special symbol success / failure determination process, a process of setting a variation pattern of the special symbol is started (S314). The gaming machine 1 of the present embodiment is provided with two special symbols, a first special symbol and a second special symbol, but the processing for determining the variation pattern is the first special symbol and the second special symbol. It is possible to share exactly the same processing for any of the symbols. This corresponds to the fact that the process in S314 is a special symbol variation pattern setting process.

  FIG. 19 is a flowchart showing a flow of a special symbol variation pattern setting process performed for setting a variation pattern of the second special symbol in the second special symbol-related process. Similar to the left special symbol related process, this process is also a process executed by the CPU 201 of the main control board 200.

  When the CPU 201 of the main control board 200 starts the special symbol variation pattern setting process (S314), it first determines whether or not the determination result of the special symbol (here, the second special symbol) is a win ( S3140). Since the special symbol success / failure determination has already been performed in the second special symbol success / failure determination processing described above with reference to FIG. 16 prior to the special symbol variation pattern setting processing, the CPU 201 of the main control board 200 performs the special symbol variation determination processing. It is possible to immediately determine whether or not the symbol determination result is a win. If the result of determining whether or not the special symbol is successful (S3140: yes), it is determined whether or not the current gaming state is short-time (that is, the short-time function is operating) (S3142). If it is medium (S3142: yes), a variation pattern table (variation pattern table for hit / shortening) to be used when the determination result is successful and the time is short is selected (S3144). On the other hand, when the time is not short (S3142: no), a variation pattern table (a variation pattern table for hit / non-time shortening) used when the determination result is true and the time is not short is selected (S3146). . These variation pattern tables are set in advance in the ROM 202 mounted on the main control board 200. The term “short time” here refers to a state in which the variable time shortening function (short time function) is in operation, and includes the probability change game.

  FIG. 20 is an explanatory diagram conceptually showing a variation pattern table for hitting / shortening time set in the ROM 202 of the main control board 200. As shown in the drawing, a variation pattern of a special symbol is set in the variation pattern table in association with the value of the variation pattern determination random number. Here, the variation pattern determination random number is a random number acquired in the special symbol variation pattern setting process of FIG. 19 in order to determine the variation pattern of the special symbol. Each variation pattern has a special symbol variation time set in advance. For example, a variation pattern “pattern special 3” is set for a value in the range of the variation pattern determination random number “0 to 85”, and the variation pattern has a variation time of 25.1 seconds for the special symbol. Is set to be a fluctuation pattern. Similarly, a variation pattern of “pattern special 4” is set for random values in the range of “86 to 172”, and this variation pattern is set to indicate that the variation time of the special symbol is 35.2 seconds. Has been.

  FIG. 21 is an explanatory diagram conceptually showing a variation pattern table for hit / non-time reduction. Similar to the variation pattern table for hit / short-time shown in FIG. 20, the variation pattern table for hit / non-time-shortness is also set with a variation pattern and variation time of a special symbol in association with the variation pattern determination random number. ing. Incidentally, the variation pattern table in FIG. 20 is a table for time reduction, and the variation pattern table in FIG. 21 is a table for non-time reduction, so that the variation pattern set in FIG. A pattern having a shorter variation time than the set variation pattern is set.

  As described above, when it is determined that the special symbol win / fail determination result is a win (S3140: yes), depending on whether the time is short or not, the variation pattern table for hit / short time or the When one of the non-time variation pattern tables is selected, a variation pattern determination random number for determining the variation pattern of the special symbol is acquired (S3148). Then, by referring to the variation pattern table based on the obtained variation pattern determination random number, the variation pattern of the special symbol when the determination result is “win” is determined (S3150).

  As described above, the processing for determining the variation pattern of the special symbol is described when the determination result of the special symbol is a win (S3140: yes in FIG. 19). However, when the determination result is wrong (S3140: no) Then, the variation pattern of the special symbol is determined as follows.

  Even if the result of determining whether or not the special symbol is correct is determined, as in the case of winning, it is determined whether or not the current gaming state is in a short time (S3152). If the time is short (S3152: yes). A variation pattern table (a variation pattern table for outlier / time reduction) used when the determination result is out of date and time is short (S3154). On the other hand, if it is not within time reduction (S3152: no), the determination result is A variation pattern table (displacement / non-temporal variation pattern table) to be used when it is out of place and not in time reduction is selected (S3156). The variation pattern table used in the case of these deviations is also set in the ROM 202 mounted on the main control board 200, similarly to the variation pattern table in the case of winning. The term “short time” here refers to a state in which the variable time shortening function (short time function) is in operation, and includes the probability change game.

  FIG. 22 is an explanatory view conceptually showing a variation pattern table for disconnection / shortening time set in the ROM 202 of the main control board 200. FIG. 23 is an explanatory diagram conceptually showing a variation pattern table for detachment / non-time reduction. As shown in the figure, the variation pattern and variation time of the special symbol are also set in association with the variation pattern determination random number in the variation pattern table when the determination result is wrong. As described above, even when the result of determining whether or not the special symbol is correct (S3140: no), depending on whether the time is short or not, the variation pattern table for out / time reduction or the variation pattern table for out / non-time reduction is displayed. Select one. Subsequently, after obtaining the fluctuation pattern determination random number (S3158), the fluctuation pattern of the special symbol when the determination result is “out” is determined by referring to the selected fluctuation pattern table (S3160).

  In the special symbol variation pattern setting process shown in FIG. 19, after determining the variation pattern of the special symbol according to the determination result of the first special symbol or the second special symbol as described above, 2 Return to special symbol related processing.

  As shown in FIG. 15, after returning from the special symbol variation pattern setting process, the CPU 201 of the main control board 200 starts the variation display of the second special symbol on the second special symbol display unit 33 (S316). Then, a process of subtracting 1 from the number of reserved for the second special symbol displayed on the second special symbol hold display section 33c is performed (S318). Next, after a command (variation pattern designation command) for designating the previously determined variation pattern of the special symbol is output to the sub-control board 220 (S320), the special symbol stop symbol (here, the second symbol) is output. A command (special symbol stop information designation command) for designating a special symbol stop symbol) is also output to the sub-control board 220 (S322), and the second special symbol-related process of FIG. 15 is terminated, and FIG. Return to the special symbol game process shown in.

  As described above, in the special symbol game process, when it is determined that the second special symbol is retained (S306: no), a series of determinations to determine whether the second special symbol is successful and to determine the variation pattern The process (second special symbol game related process) has been described. On the other hand, when it is determined that the second special symbol hold does not remain (S306: yes), it is determined whether or not the first special symbol hold remains (S326). If the first special symbol hold remains (S326: no), the random number stored at the earliest timing is selected from the first special symbol determination random numbers stored in the RAM 203. After reading (S328), the first special symbol related process described below is started (S330).

C-2-2. First special symbol related processing:
FIG. 24 is a flowchart showing the flow of the first special symbol related process. Since the first special symbol related process is substantially the same as the second special symbol related process described above with reference to FIG. 15, the first special symbol related process will be briefly described based on the description of the second special symbol related process. Also in the first special symbol related process, as in the second special symbol related process described above, when the process is started, first, whether or not the first special symbol is determined is determined (S332). The success / failure determination of the first special symbol can be performed by referring to the success / failure determination table in substantially the same manner as the determination of the success / failure of the second special symbol described above with reference to FIG. Hereinafter, a brief description will be given with reference to FIG. 16. First, it is determined whether or not the probability change is in progress. If the probability change is in progress, a decision table for probability change is selected (corresponding to S3122). A wrong / no-good decision table is selected (corresponding to S3124). As described above, the second special symbol table can be used as the success / failure determination table referred to at this time.

  Next, a process of determining a big hit symbol of the first special symbol if the determination result is a win, and conversely, if the determination result is not true, a process of determining a loss symbol of the first special symbol is started. That is, when the determination result is a win (S3126: equivalent to yes), by referring to the hit symbol determination table for the second special symbol from the symbol determination random number for the second special symbol, the big hit of the second special symbol A symbol is determined (corresponding to S3130). On the other hand, if the result of the determination is wrong (S3126: equivalent to no), the second special symbol is missed by referring to the second special symbol's missing symbol determination table from the symbol special random number for the second special symbol. A symbol is determined (corresponding to S3134). At this time, the winning symbol determination table for the first special symbol is different from the winning symbol determination table for the second special symbol shown in FIG.

  FIG. 25 is an explanatory diagram illustrating a hit symbol determination table for the first special symbol. As is apparent from the comparison with the winning symbol determination table for the second special symbol shown in FIG. 18, in the winning symbol determination table for the first special symbol, the big winning symbol of the special probability variation mode (that is, green “Y”). -The random number range assigned to the red symbol “.” Is narrower than the hit symbol determination table for the second special symbol. As a result, the special probability variation is less likely to occur for the first special symbol, and conversely, the special probability variation is likely to occur for the second special symbol. As described above, when the determination result of the first special symbol is a win, the big hit symbol of the first special symbol is determined by referring to the winning symbol determination table for the first special symbol.

  On the other hand, when the determination result of the first special symbol is unacceptable, the deviating symbol of the first special symbol is determined by referring to the deviating symbol determination table for the first special symbol. In addition, regarding the off symbol determination table, unlike the winning symbol determination table, the same table as the table for the second special symbol can be used. In S332 of the first special symbol related process shown in FIG. 24, whether or not the first special symbol is true is determined as described above, and the process of determining the big hit symbol or the off symbol for the first special symbol is performed.

  Next, also in the first special symbol related process, the special symbol variation pattern setting process is performed in the same manner as the second special symbol related process described above (S334). Such variation pattern setting processing can be performed in exactly the same manner as the processing performed in the second special symbol related processing. That is, the corresponding variation pattern table is selected according to the determination result of the first special symbol and whether or not the current gaming state is short. Then, a variation pattern determination random number is acquired, and the variation pattern of the special symbol is determined by referring to the selected variation pattern table.

  After the variation pattern of the special symbol is determined as described above, the first special symbol display unit 30 starts the variation display of the first special symbol (S336 in FIG. 24), and the first special symbol hold display unit 30c. 1 is subtracted from the number of first special symbols held (S338), and a command for designating the variation pattern of the special symbol determined earlier and a command for designating the stop symbol of the first special symbol are After output to the control board 220 (S340, S342), the first special symbol related process shown in FIG. 24 is terminated, and the process returns to the special symbol game process shown in FIG.

  The CPU 201 of the main control board 200 determines the variation pattern and stop symbol of the first special symbol or the second special symbol as described above, and sends the variation pattern designation command and the special symbol stop information designation command to the sub-control board 220. When the data is output toward the, the special symbol game process shown in FIG. 13 is terminated, and the game control process shown in FIG. 9 is resumed.

  The detailed process performed in the special symbol game process when either the first special symbol or the second special symbol is not variably displayed (that is, S302: no in FIG. 13) has been described above. On the other hand, when the special symbol game process of FIG. 13 is started while either the first special symbol or the second special symbol is fluctuating, “yes” is determined in the determination of S302 performed first. This case corresponds to the case where the variation pattern of the special symbol and the stop symbol are already determined and the variation of the first special symbol or the second special symbol is started. Therefore, it is determined whether or not the special symbol variation time has elapsed (S348). That is, since the variation time of the first special symbol or the second special symbol is determined in advance according to the variation pattern, by setting the timer at the same time as starting the variation of the first special symbol or the second special symbol, It is determined whether or not the fluctuation time has elapsed. If the variation time has not yet elapsed (S348: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, if it is determined that the variation time has elapsed (S348: yes), a command (design stop command) indicating that the special symbol being varied is to be stopped and displayed is output to the sub-control board 220. Along with (S350), the first special symbol or the second special symbol that is being displayed in a variable manner is stopped and displayed at a preset symbol (S352). Next, after setting a time (stop display time) for holding the special symbol displayed in a stopped state in a stopped state (S354), it is determined whether or not the set stop display time has passed (S356). If the stop display time has not elapsed (S356: no), the special symbol game process is terminated as it is, and the process returns to the game control process shown in FIG.

  On the other hand, when the stop display time has elapsed (S356: yes), it is determined whether or not the stop-displayed symbol is a symbol that will activate the conditional device (S358 in FIG. 14). Here, the symbol that activates the condition device is any of the normal hit symbol, the probability variation symbol, or the special probability variation symbol shown in FIG. 8 (that is, the big hit symbol). The gaming machine 1 of the present embodiment is equipped with two symbol display devices, a first symbol display device 28 and a second symbol display device 32, and the first symbol display device 28 has a variation of the first special symbol. Display and stop display are possible, and the second symbol display device 32 can display variation and stop display of the second special symbol, but the big hit symbol is either the first special symbol or the second special symbol. The stop may be displayed.

  If the symbol that is stopped and displayed on either the first symbol display device 28 or the second symbol display device 32 is a symbol that activates the condition device (S358: yes), the stop symbol is a special probability change. It is determined whether the symbol is a winning symbol (S359). If it is determined that the symbol is a special probability variation symbol (S359: yes), the operation mode of the special winning device 31 is set to a special mode (S361). On the other hand, when it is determined that the symbol is not a special probability variation symbol (S359: no), the operating mode of the special winning device 31 is set to the normal mode (S360). Here, the condition device is a device for playing a big hit game by opening the special winning opening 31d (that is, by operating the special winning device 31), and is mainly configured by the CPU 201 of the main control board 200. . In order for the accessory continuous action device to be described later to operate, it is a condition that the condition device is operating, so it is called a “condition device”.

  In addition, as will be described in detail later, in this embodiment, when the condition device is activated, either a normal mode jackpot game or a special mode jackpot game is executed. When the operation mode of the big prize device 31 is set to the normal mode, when the condition device is activated, the big prize device 31 is opened in the normal mode in which the big prize opening 31d is opened and closed once per round game. A big hit game that is activated and repeats such a round game a plurality of times is performed. On the other hand, when the operation mode of the special winning device 31 is set to the special mode, when the condition device is operated, the special winning device is configured to open and close the special winning port 31d a plurality of times per round game. 31 is activated, and a big hit game in which such a round game is repeated a plurality of times is performed. As a result, in the special symbol game processing of the present embodiment shown in FIG. 14, the operating pattern of the special winning device 31 is set according to the stop symbol of the first special symbol or the second special symbol. If it is a symbol (S359: yes), a round game in which the special winning device 31 operates in a special manner is performed, and if it is a winning symbol other than that (S359: no), it is large in the normal manner. A round game in which the winning device 31 operates is performed. In the gaming machine 1 of the present embodiment, the time required for one round game (round game time) is set to about 27 seconds when the operation mode of the big prize winning device 31 is set to the normal mode. When the mode is set, it is set to about 40.5 seconds. As will be described in detail later, when the special winning device 31 operates in a special manner, the special winning opening 31d is repeatedly opened and closed during the round game, and the special winning entrance 31d is closed. Since time is generated, in consideration of this, the round game time is set longer in the special mode than in the normal mode.

  After setting the embodiment of the round game (the operation mode of the big prize device 31) in this way, the number of round games (number of round games) is set (S362). Although the number of round games can be a fixed value, in the gaming machine 1 of the present embodiment, the number of round games is set by performing lottery with random numbers.

  As described above, when the operation mode of the winning device 31 and the number of round games are set (S360 to S362), the operation of the condition device and the accessory continuous operation device is started (S363). Here, the accessory continuous operation device is a device for starting a new round game again after the end of the round game, and is mainly configured by the CPU 201 of the main control board 200. As will be described in detail later, when the condition device and the accessory continuous operation device are operated, when the special symbol game process is exited and the game control process of FIG. 10 is resumed, the special electric accessory game process is started and preset. A special game state (so-called big hit game) is started after the number of round games are performed. It should be noted that the CPU 201 of the main control board 200 outputs a big hit game start command to the sub control board 220 with the start of operation of the condition device and the accessory continuous action device (start of the big hit game). This jackpot game start command is stored in advance in the ROM 202 of the main control board 200 according to the operation mode of the big winning device 31 set in S360 or S261 and the number of round games set in S362. The CPU 201 outputs a jackpot game start command corresponding to the current jackpot game to the sub-control board 220 at the start of operation of the condition device and the accessory continuous action device (at the start of the jackpot game). Then, the CPU 221 of the sub-control board 220 can specify the operation mode of the big winning device 31 and the number of round games in the current big hit game based on the big hit game start command.

  Further, in the gaming machine 1 of this embodiment, the probability changing function and the time shortening function do not work when the condition device and the accessory continuous operation device are operated. The time reduction function is a function for shortening the time for which the symbols are variably displayed on the first symbol display device 28, the second symbol display device 32, and the variation display device 27. Accordingly, when the condition device and the accessory continuous operation device are operated in S363 of FIG. 14, it is determined whether or not the current gaming state is being changed (S364). If the probability change is being performed (S364: yes), since the probability change function and the time reduction function are activated, these functions are stopped (S365, S366). On the other hand, if the current gaming state is not in a certain change (S364: no), then it is checked whether or not the time is short (S367). If the time is short (S367: yes), the time saving function Is stopped (S366). Further, in the gaming machine 1 of the present embodiment, when the time reduction function is activated, the function of extending the opening time of the second start port 17b (ordinary electric accessory) provided in the start port unit 17 also works. Therefore, if the time-shortening function is stopped (S366), the function for extending the normal electric accessory opening time is also stopped (S368), and then the special symbol game process shown in FIGS. Return to control processing. On the other hand, if the game state when the condition device and the accessory continuous operation device are operated is neither probabilistic nor short (S367: no), the special symbol game process is exited and the game control process is resumed.

  As described above, the symbol stopped on the first symbol display device 28 or the second symbol display device 32 (that is, the first special symbol or the second special symbol) is the symbol (big hit symbol) that activates the condition device. (S358: yes), the process has been described, but when the symbol that is stopped and displayed is not a symbol that activates the conditional device (if it is a disjoint symbol) (S358: no), Process.

  First, it is determined whether or not the current gaming state is short of time (S374). If it is determined that the time is short (S374: yes), after counting the number of fluctuations of the special symbol during the time reduction (S376), it is determined whether or not the number of fluctuations has reached a predetermined number (S378). As described above, in the gaming machine 1 according to the present embodiment, in either case of “normal hit” or “probable hit (including special probability change)”, the time-short state is started after the end of the special game, and the next big hit game It is set to continue until a state occurs or the special symbol fluctuates a predetermined number of times. Therefore, when it is determined that the current gaming state is short of time (S374: yes), after counting the number of fluctuations of the special symbol (S376), it is determined whether or not the count value of the number of fluctuations has reached a predetermined number. To do. In the gaming machine 1 of the present embodiment, since two special symbols of the first special symbol and the second special symbol are provided, in S376, the number of fluctuations of each special symbol is counted together. If the number of times of the variation of the first special symbol and the second special symbol has reached the predetermined number (S378: yes), the time reduction function is stopped (S380), and then the normal electric accessory opening time After the extension function is also stopped (S368), the special symbol game process shown in FIGS. 13 and 14 is exited and the process returns to the game control process shown in FIG. On the other hand, if the number of times of the variation of the first special symbol and the second special symbol has not yet reached the predetermined number of times (S378: no), the special symbol game process is exited while maintaining the short time state. Return to 10 game control processing.

  It should be noted that the lottery regarding whether or not to start the jackpot game, and the lottery regarding which mode to play the jackpot game when the jackpot game is started is the second in the special symbol game process shown in FIG. This process is performed in the first special symbol related process (S330) or the second special symbol related process (S310). Therefore, the CPU 201 mounted on the main control board 200 of this embodiment that performs these processes corresponds to the “big hit game lottery means” in the present invention.

  As shown in FIG. 10, in the game control process, when returning from the special symbol game process, it is determined whether or not the condition device is in operation (S390). As described above, the condition device is a device that starts the special game state by operating the special winning device 31 and the accessory continuous operation device. Therefore, the CPU 201 mounted on the main control board 200 starts the special electric accessory game process described below if the condition device is operating (S400). On the other hand, if the condition device is not in operation (S390: no), the special electric accessory game process (S400) is skipped, the process returns to the top of the game control process, and a series of the above-described prize ball related process (S50) and subsequent steps. Repeat the process.

C-3. Special electric game game processing:
FIG. 26 is a flowchart showing a part of the special electric accessory game process. FIG. 27 is a flowchart showing the remaining portion of the special electric accessory game process. By executing the special electric accessory game process, a so-called special game state (big hit game) is started. Hereinafter, the special electric accessory game process will be described with reference to FIG. 26 and FIG. 27. As preparation, the contents of a game called a special game state will be briefly described.

  As described above with reference to FIG. 2, a special winning opening 31d is provided below the game board, and the special winning opening 31d is closed in a normal gaming state. However, when the special game is started, the special winning opening 31d is opened. The “special electric accessory” referred to in the present specification is an accessory provided with a special winning opening 31d. In the gaming machine 1 of the present embodiment, the operation mode of the special winning device 31 includes a normal mode in which the special prize opening 31d is kept open during the round game, and a special prize opening 31d during the round game. Two operating modes are provided which are special modes that open and close. Even if the big winning device 31 is operated in any manner, during the round game, the game ball enters the big winning opening 31d with a high probability. In addition, in a round game, a predetermined round game time (about 27 seconds in the normal mode and about 40.5 seconds in the special mode) elapses in the gaming machine 1 of this embodiment, or a predetermined number of game balls enter. The game ends when the ball is played, but the round game starts again after a predetermined time has elapsed. In the present specification, the time between round games is referred to as “interval time”. Until the interval time elapses, the special winning opening 31d is in a closed state. When the round game is repeated in this manner and a predetermined number of round games are consumed, the special game state (so-called big hit game) is finished. Hereinafter, a special electric accessory game process performed by the CPU 201 of the main control board 200 in order to execute the special game described above will be described with reference to FIGS. 26 and 27. FIG.

  As shown in FIG. 26, when the CPU 201 of the main control board 200 starts the special electric accessory game process (S400), first, the big prize device 31 is in operation (that is, the round game is being executed). Whether or not (S402). Since the big winning device 31 is activated when starting the big hit game (see S363 in FIG. 14), the big winning device 31 is not activated in the normal gaming state. When the big winning device 31 is not operating, it is determined as “no” in S402, and subsequently, it is determined whether or not the number of round games has reached the set number (S404). In the special symbol game processing described with reference to FIGS. 13 and 14, the number of round games to be performed is set prior to operating the condition device (S362 in FIG. 14). If it is determined in the game process that the grand prize winning device 31 is not operating (S402 in FIG. 26: no), whether or not the grand prize winning device 31 has stopped operating because the set number of round games have been performed. It is determined whether or not (S404).

  Immediately after the big hit game is started, since the number of round games has not reached the set number (S404: no), a new round game will be started. It is determined whether or not the interval time has elapsed (S406). That is, as described above, an interval time of a predetermined time is provided between the round game and the round game, and the special winning opening 31d is closed during the interval time. Immediately after the big hit game is started, it is determined that the interval time has passed since the long time has already passed since the end of the previous round game (S406: yes). In this case, since the number of round games has not reached the set number of times and the interval time has elapsed, after operating the big winning device 31 to start the round game (S408) 26, the special electric accessory game process shown in FIG. 26 is temporarily ended, and the process returns to the game control process shown in FIG. On the other hand, if it is determined that the interval time has not elapsed (S406: no), the special electric equipment game process of FIG. 26 is temporarily terminated without operating the special winning device 31, and FIG. Return to the game control process.

  When the CPU 201 of the main control board 200 returns to the game control process, as shown in FIG. 10, after performing a series of various processes after the prize ball related process (S50), the special electric game game process (S400) again. To start. As described above, the time required for the CPU 201 of the main control board 200 to execute the game control process shown in FIG. 10 once is about 4 msec. Therefore, the special electric accessory game process shown in FIGS. 26 and 27 is also executed about every 4 msec. As long as the set number of round games have not ended, the big prize winning device 31 will eventually be activated, and the next time the special electric accessory game process of FIGS. 26 and 27 is started, in S402, It is determined that the big prize winning device 31 is operating (S402: yes).

  If it is determined that the grand prize winning device 31 is operating (that is, the round game is being executed) (S402: yes), it is determined whether or not the operating time of the big prize winning device 31 has reached a predetermined time (one round gaming time). Judgment is made (S410). As described above, when the big winning device 31 is activated and the round game is started, a predetermined round game time (about 27 seconds in the normal mode, about 40.5 seconds in the special mode) elapses or is large. The large prize winning device 31 operates until a predetermined number (10 in this embodiment) of game balls enter the winning opening 31d. In response to this, in S410, it is determined whether or not the operating time of the special winning device 31 has reached a predetermined round game time. Then, if the operation time of the big winning device 31 has reached the round game time (S410: yes), after the operation of the big winning device 31 is stopped (S414), the special electric game game process shown in FIG. 26 is performed. Exit and return to the game control process of FIG. On the other hand, if the operating time of the special winning device 31 has not reached the predetermined time (S410: no), it is determined whether or not the number of game balls that have entered the special winning opening 31d has reached a specified number (S412). Even when the number of game balls reaches the specified number (S412: yes), the operation of the special winning device 31 is stopped (S414). On the other hand, if the specified number has not been reached (S412: no), the operating time of the big winning device 31 has not yet reached the predetermined round gaming time, and the gaming ball has entered the big winning opening 31d. Since the predetermined number has not been reached, the special electric game game process shown in FIG. 26 is exited while the special winning device 31 is operated, and the process returns to the game control process of FIG.

  While the game control process of FIG. 10 is repeatedly executed, whether the operation time of the big prize device 31 reaches a predetermined round game time (S410: yes), or a prescribed number of games in the big prize port 31d The ball enters (S412: yes), and the operation of the special winning device 31 is stopped (S414). Thus, one round of game is completed. Then, when the special electric accessory game process is executed next, it is determined in S402 that the special winning device 31 is not operated (S402: no), and it is determined whether or not the number of round games has reached the set number. If the set number of times has not been reached (S404: no), it is confirmed that the interval time has passed (S406: yes), and then the big winning device 31 is operated again to start a new round ( S408). On the other hand, when it is determined in S404 that the number of round games has reached the set number (S404: yes), the operation of the condition device and the accessory continuous operation device is stopped in order to end the jackpot game (FIG. 27). S416). In this way, the big win game is executed by repeating the round game by operating the big winning device 31 until the number of round games reaches the set number. Further, as described above, the two types of operation modes of the normal mode and the special mode are set in the special winning device 31 of the present embodiment. Therefore, depending on which operation mode of the big winning device 31 is set, the big hit game is also performed in a different mode.

  FIG. 28 is an explanatory view conceptually showing a state in which the big hit game progresses in different modes depending on the operating mode of the big winning device 31. FIG. 28A shows a case where the operation mode of the special winning device 31 is set to the normal mode. When the normal mode is set, when the big winning device 31 starts operating and a round game is performed, the big winning port 31d is immediately opened and the open state is maintained as it is during the round game. When the prize winning device 31 stops operating, the prize winning opening 31d is immediately closed and the first round game is ended. Next, when the special winning device 31 is activated again after the interval time has elapsed with the special winning opening 31d closed, the special winning opening 31d is opened and a new round game is started. In the gaming machine 1 of this embodiment, the interval time between round games is set to about 2 seconds.

  In this way, when the operation mode of the big winning device 31 is set to the normal mode, the simple winning port 31d is opened during the round game, and when the round game ends, the big winning port 31d is closed. In the aspect, the big hit game is played until the number of round games reaches the set number. In FIG. 28, the hatched rectangle represents the period during which the big prize opening 31d is closed, while the white rectangle represents the period during which the big prize opening 31d is open. ing. Further, when the special winning opening 31d is opened (at the start of opening), a command indicating that the special winning opening 31d is opened from the CPU 201 of the main control board 200 to the CPU 221 of the sub control board 220 (opening of the special winning opening). On the other hand, when the special winning opening 31d is closed (at the start of closing), a command indicating that the special winning opening 31d is closed (a special winning opening closing command) is output. Further, at the start of the round game, a command (round number designation command) indicating the number of round games of the round game is also output. The white arrow shown in FIG. 28 represents the big prize opening command, and the hatched arrow represents the big prize closing command. A solid line arrow represents a round number designation command.

  On the other hand, when the operating mode of the special winning device 31 is set to a special mode, the opening and closing of the special winning port 31d are repeated during the round game. FIG. 28 (b) conceptually shows how the opening and closing of the special winning opening 31d are repeated during a round game. In the gaming machine 1 of the present embodiment, the opening time for one opening of the special winning opening 31d during the round game of the special mode is set to about 2.7 seconds, and the closing time is set to about 1.5 seconds. Has been. The operation of opening and closing the special winning opening 31d at regular intervals is repeated until the round gaming time elapses or until a specified number of gaming balls enter the special winning opening 31d. Thereafter, until the interval time elapses, the special winning opening 31d is in a closed state, and after the interval time has elapsed, a new round game is started, and the operation of opening and closing the special winning opening 31d at regular intervals is repeated. It has become.

  In the gaming machine 1 of the present embodiment, the interval time during which the special winning opening 31d is closed between the round game and the round game is set to about 2 seconds, and this time is set during the round game of the special mode. It is set to be almost the same as the time (about 1.5 seconds) when the special winning opening 31d is closed. This makes it difficult for the player to distinguish between the round game and the round game when the grand prize opening 31d is closed and whether it is closed during the round game or because the round game is closed. Can not do. As a result, the player recognizes the big hit game of the special mode as if it is one game state in which the state where the big winning opening 31d is repeatedly opened and closed is not repeated in a plurality of round games. To come. At the start of a new round game, a round number designation command is output from the main control board 200, so that the sub-control board 220 can recognize the division between the round game and the round game.

  In the special electric accessory game process of the present embodiment, when the big hit game is ended and the operation of the condition device and the continuous accessory action device is stopped (S416 in FIG. 27), the big hit game end command for informing the end of the big hit game. Is output toward the sub-control board 220 (S418). Next, it is determined whether the first special symbol or the second special symbol (big hit symbol) that caused the condition device to operate is “normal hit symbol” or “probable variable symbol (including special probability variable symbol)”. (S420). If it is based on the “probability variation symbol” (S420: yes), after the operation of the probability variation function is started (S422), the operation of the time reduction function and the opening time extension function of the ordinary electric accessory is started. (S424, S426), the special electric accessory game process shown in FIGS. 26 and 27 is terminated. On the other hand, when it is determined that the first special symbol or the second special symbol that causes the condition device to operate is not “probable hit symbol” (S420: no), the condition device operates according to “normal hit symbol”. It will be done. Therefore, the process of starting the operation of the probability changing function (S422) is skipped, the operation of the time reduction function is started (S424), and then the operation of the normal electric accessory opening time extension function is started (S426). The special electric accessory game process shown in FIG. 26 and FIG. 27 is terminated, and the process returns to the game control process of FIG.

  Note that the big hit game in this embodiment is performed by the CPU 201 mounted on the main control board 200 executing the above-described special electric accessory game process. Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “big hit game execution means” in the present invention. In addition, when the operation of the probability changing function is started in the special electric accessory game process, the subsequent game is performed in a probability changing state (that is, a state in which the probability of jackpot occurrence is set higher than the normal state). . Therefore, the CPU 201 mounted on the main control board 200 of this embodiment corresponds to the “probability changing means” in the present invention.

  The CPU 201 mounted on the main control board 200 advances the game of the gaming machine 1 by repeatedly performing the game control process as described above. Then, in the special symbol game process during the game control process, whether the first special symbol or the second special symbol is determined (S312 in FIG. 15 or S332 in FIG. 24), the first special symbol or the second special symbol is determined. If the determination result is “hit” in any of the two special symbols, the condition device and the accessory continuous operation device are activated (S360 in FIG. 14), and the special game state (hit game) is started. In addition, the CPU 201 of the main control board 200 sends various commands such as a special symbol variation pattern designation command, a special symbol stop information designation command, and a symbol stop command to the sub-control board 220 while performing such processing. Output.

  The sub control board 220 determines the contents of the effect based on various commands received from the main control board 200 (variation pattern designation command, special symbol stop information designation command, symbol stop command, etc.). Then, according to the determined contents, various LEDs and lamps are turned on or blinked, and the amplifier board 224 is driven to output sound effects from various speakers. Further, by outputting a control command to the effect control board 230, an effect using the design symbols 27a, 27b, 27c and the background symbol 27d is executed on the variable display device 27, so that the player's game It is possible to excite the interest for.

  The effects described above are realized by software control performed mainly by the main control board 200, the sub control board 220, and the like. However, in the gaming machine 1 of the present embodiment, it is possible to produce an effect that enhances the interest of the player even by a method that does not depend on software control, and the effect is controlled by the game control described above by the main control board 200. It is realized naturally by executing the process. For this reason, not only the processing of the main control board 200 that controls the progress of the game, but also the processing of the sub-control board 220 that controls various controls related to the production, the player's interest is further enhanced without any complexity. Production is possible. In the following, the reason why such an effect is possible and the contents of the effect will be described in detail.

  As described above with reference to FIG. 2, the gaming machine 1 of this embodiment is equipped with two start ports, the first start port 17a and the second start port 17b. In addition, as shown in FIG. 5, the second start port 17b hardly receives game balls in the normal state. Therefore, in the normal state, the game balls enter the first start port 17a exclusively. To do. When a game ball enters the first start port 17a, the first symbol display device 28 starts the variable display of the first special symbol, and when the stop symbol is displayed with the winning symbol, the big hit game is started. Here, as shown in FIG. 28, there are a normal mode and a special mode in the mode of the big hit game, but the first special symbol hardly stops at the special probability variable per symbol, so the special mode. The jackpot game is rarely played. For this reason, the big hit game is played in the normal mode, and after the big hit game is finished, the short-time game is started.

  Here, as described above, in the short-time game, the opening time extension function of the ordinary electric accessory operates, so that the opening time of the second start port 17b is extended, and the normal symbol variation time (and the first special symbol) is also increased. , The variation time of the second special symbol) is shortened, and the opening frequency is also increased. As a result, after the big hit game is over, the operation of opening the second start port 17b becomes more conspicuous than before the start. When the second start port 17b is in the open state, the game ball is easier to enter the second start port 17b than the first start port 17a, and still enters the first start port 17a. Many game balls enter the second start port 17b. As described above, when a game ball enters the second start port 17b, the second special symbol starts to change, and when the winning symbol is stopped and displayed in the second special symbol, the big hit game is started. Here, since the probability that the second special symbol is stopped and displayed with the special probability variation symbol is high, the probability that the big hit game is a special big hit game is high. In the special mode jackpot game, as described above, the big prize opening 31d is repeatedly opened and closed throughout the jackpot game.

  As described above, in the gaming machine 1 according to the present embodiment, the first start port 17a into which the game ball enters mainly in the normal game state and the second start port 17b into which the game ball enters mainly in the time-short state. The jackpot game that occurs when entering the first starting port 17a is likely to be in the normal mode, and the jackpot game that occurs when entering the second starting port 17b is in a special mode. The probability is set high. As a result, it is possible to give the player an impression as if the following effects are being performed. That is, in the normal gaming state, the second start port 17b opens only for a moment, and the opening frequency is not high. The special winning opening 31d is in a closed state. When a big hit game is generated from this state, the big winning opening 31d is in an open state, and the normal style big hit game is easily started. In the big hit game in the normal mode, the big winning opening 31d is closed at the end of one round of the game, and the big hit game proceeds with an open state at the start of the next round.

  After the big hit game is over, the state becomes shorter and the state where the second start port 17b repeats opening and closing becomes conspicuous, and when the big hit game is generated from that state, the mode of the big hit game has a high probability and a special mode. It becomes. This special mode of big hit game is a game state in which the movement of the big winning opening 31d that repeats opening and closing is very conspicuous throughout the big hit game. Then, following the short game when the opening / closing operation of the second starting port 17b is conspicuous, the big hit game where the opening / closing operation of the special winning opening 31d is conspicuous is started, so that there is some relationship between the two game states for the player. As a result, as a result of playing the big hit game (big hit game started from the normal game state) at the beginning, it is as if "special game components that perform opening and closing operations frequently repeat opening and closing operations. It feels as if it has shifted to the “nasty gaming mode”.

  FIG. 29 conceptually shows that the gaming machine 1 according to the present embodiment starts the normal big hit game from the normal gaming state and starts the short-time game after the big hit game ends as described above. Yes. As shown in the drawing, in the normal gaming state, the special winning opening 31d is closed, and the second start opening 17b is opened only for a moment even if it is opened. In the big hit (so-called first hit) generated from this state, the big prize opening 31d opens and closes at the end of one round of the game, but in other cases, the big prize opening 31d remains open. The start port 17b is in a closed (upright) state. In the short game after the first hit, the second start port 17b is repeatedly opened and closed, and the big hit game generated from the short time state has a high probability of a special type of big hit, that is, the big winning port 31d is between one round game. Also, a special mode of big hit game state in which opening and closing is repeated, and after the big hit game is over, the game becomes a time-saving game again and the second start port 17b is in a state of repeated opening and closing. In FIG. 29, the state where the second start opening 17b or the special winning opening 31d repeats opening and closing is indicated by hatching.

  Of course, when a certain condition is satisfied, it is possible to shift to a special game mode set in advance and perform an effect peculiar to the game mode itself by software control on the main control board 200 or the sub control board 220. This can also be realized by performing the above. However, if such an effect is to be realized by software control, not only the control of the sub-control board 220 that controls the effect but also the control on the main control board 200 in many cases is very complicated. turn into. On the other hand, in the gaming machine 1 according to the present embodiment, since the main control board 200 and the sub control board 220 do not need to perform any special control, the contents of the control can be greatly simplified. . As a result, the development of the gaming machine is facilitated, the number of control bugs is reduced, and a highly reliable gaming machine can be provided.

  In addition, in the gaming machine 1 of the present embodiment, the above-described mode (a mode in which the big winning opening 31d repeats opening and closing operations during the big hit game) is set as a special type of big hit game. It aims at the effect like. In other words, during the big hit game, by performing an operation that the big prize opening 31d keeps opening and closing during the round game, a conventional general big hit game (a big hit game that opens and closes the big prize opening every round) A kind of strange impression can be given to players who are used to. However, since the big winning opening 31d is repeatedly opened and closed, the game ball has entered the big winning opening 31d with a high probability, and the winning ball is also paid out. Therefore, the player continues the game while thinking, “Maybe this gaming state is an advantageous state in which the big prize opening repeats opening and closing operations with high frequency”. At this time, if the player knows that the round game has been digested, this jackpot game will eventually be over, but as described above, in the special mode jackpot game The division between round games and round games is not understood. Therefore, the player does not know that he is digesting the round game, and can continue the game while expecting to the end that “this advantageous game state will last”.

  Of course, in practice, the big hit game is ended by digesting the prescribed round game, but this time, the short game is started when the operation of the second start port 17b repeating opening and closing is conspicuous. As a result, the player continues to play the game, thinking that "Maybe any opening / closing member mounted on the gaming machine has shifted to a special game mode that repeats opening / closing operations at a high frequency at all times". To do. And as mentioned above, when there is a hold on both the first special symbol and the second special symbol, the hold on the second special symbol is preferentially consumed, so it becomes a short-time game once. When it becomes easy for a game ball to enter the second start port 17b, the variable display is performed with the second special symbol. As a result, the special hit game is likely to occur again, so that the big win game 31d is repeatedly opened and closed as if the player had a good feeling. Become so.

  As described above, in the gaming machine 1 of the present embodiment, whether or not the game machine 1 has shifted to a special game mode (or a runaway state in a form preferable to the player) by utilizing the fact that the big hit game can be executed in a special mode. Such an impression can be given to the player, and it is possible to greatly excite the interest in the game. Nevertheless, the contents of the control performed by the main control board 200, the sub control board 220, etc. are not complicated at all, and it is possible to use exactly the same control contents as those generally used for gaming machines. It becomes possible.

  The embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments, and the present invention is not limited to the wording of each claim without departing from the scope described in each claim. Can be easily replaced by these, and improvements based on knowledge that a person skilled in the art normally has can be added as appropriate.

  For example, in the above-described embodiment, it has been described that the opening time of the second start port 17b is extended during the short-time game. However, in addition to the extension of the opening time, the opening may be performed a plurality of times. In this way, during the short-time game, the second start port 17b can be opened with a higher frequency, so that after the big hit game by the first hit, the game has changed to a special game state. Such an impression can be strongly given to the player.

  In the above-described embodiments, the special mode jackpot game is described as occurring only in the case of a probable hit. Of course, a special mode jackpot game may be performed in the case of a normal hit. Furthermore, in the above-described embodiment, even when the first special symbol is displayed in a variable manner, a special style jackpot game may be started. Conversely, even if the second special symbol is displayed in a variable manner, It was explained that the big hit game of the normal mode may be started without any. However, when the first special symbol is variably displayed, the special mode jackpot game is not started. When the second special symbol is variably displayed, the special mode jackpot game is always started. Anyway. This also makes it possible to give a strong impression to the player as if he / she has transitioned to a special gaming state after the end of the big hit game.

  In the above-described embodiment, the first start port 17 a and the second start port 17 b are described as being integrated into one start port unit 17. However, the first start port 17a and the second start port 17b do not have to be combined as one unit, and may be provided as separate start ports at different locations on the game board 10. . Furthermore, the number of the first start ports 17a and the second start ports 17b is not necessarily one, and a plurality of first start ports 17a or second start ports 17b may be provided. In this case, the number of first start ports 17a and the number of second start ports 17b can be different from each other.

  In addition, at this time, if the number of the second start ports 17b is larger than that of the first start ports 17a, the following effects can be obtained. That is, in the gaming machine 1 of the above-described embodiment, once a big hit game is generated, it becomes easy for a game ball to enter the second start port 17b, and therefore, more second start ports than the first start port 17a. By providing 17b, it is possible to make it easier to enter the ball by the second start port 17b after the big hit game. As a result, it is possible to give the player an even stronger impression that the game has shifted to a completely different gaming state by completing the first big hit game.

  In the above-described embodiment, one type of special probability variation symbol is used. However, a plurality of types of special probability variation symbols are set, and a special mode of big hit game with a different number of continuations is generated for each special probability variation symbol. You may make it make it. That is, the big hit game of the special embodiment of the above-described embodiment, although it is difficult to understand the end timing, is actually ended by digesting 15 round games. On the other hand, for example, 15 types of different special probability variation symbols are set for the second special symbol, and the number of times different for each special probability variation symbol (for example, 15, 14, 13,...). (3 times, 2 times, 1 time) round game is set respectively. As a result, during a short-time game, a special mode jackpot game with a different number of rounds can be generated, and the continuation rate (duration) of the special mode jackpot game can be varied. Therefore, it is possible to make it difficult to understand the end timing of the special mode jackpot game, and it is possible to effectively enhance the game interest of the player who performs the special mode jackpot game.

  Further, in the above-described embodiment, the winning symbol corresponding to the special mode jackpot game is “special probability variation winning symbol”, and after the special mode jackpot game, the short-time game in the probability variation state is performed, but it is limited to this. It is not a thing, but a special bonus symbol is provided separately for the winning symbol corresponding to the special bonus game, and after the special bonus bonus game in this special bonus symbol, a short-time game in a non-probable change state is performed. Also good. By doing so, it is possible to give variations to the gaming state after the big hit game of the special mode.

  In the embodiment described above, when determining the big hit mode, the symbol determination random number of the first or second special symbol is collated with the hit symbol determination table corresponding to each special symbol. A plurality of determination tables may be provided for each gaming state. For example, as a winning symbol determination table, a short-term per symbol determination table used in a time-short state (that is, a state in which the opening time extension function is activated. A special symbol determination table is prepared for each special symbol. Among these, the symbol determination table for non-time reduction for collating the symbol determination random number of the second special symbol is the same as the symbol determination table of FIG. 18 of the above-described embodiment. In addition, as the shortening per symbol determination table, a symbol determination random number corresponding to “probable variation” in the symbol determination table of FIG. 18 is changed to “special probability variation”.

  In this way, by assigning the symbol determination random number for “special probability variation per” in the symbol determination table for time reduction more than the distribution of symbol determination random numbers for “special probability variation” in the non-time reduction symbol determination table. As a big hit game mode during a short-time game, a special type of big hit game can be made more frequent. As a result, it is possible to give the player a stronger impression that the game state has been switched to a new gaming state by the first hit. In this case, the winning symbol determination table in FIG. 18 corresponds to the “second lottery table” in the present invention, and the ratio of “special probability variation winning” is increased with respect to the winning symbol determination table in FIG. The table corresponds to the “third lottery table” in the present invention. Further, the winning symbol determination table of FIG. 25 corresponds to the “first lottery table” in the present invention.

  Alternatively, the following winning symbol determination table may be provided for each gaming state. For example, as the winning symbol determination table, a probability variation hit symbol determination table used in the probability variation state and a non-probability variation symbol determination table used in the non-probability variation state are prepared for each special symbol. Among these, the symbol determination table for non-probability change for collating the symbol determination random number of the second special symbol is the same as the symbol determination table of FIG. 18 of the above-described embodiment. Further, as the probability variation per symbol determination table, the symbol determination random number corresponding to “probability variation” in the symbol determination table of FIG. 18 is changed to “special probability variation per unit”.

  In this way, by assigning the symbol determination random number for “special probability variation per” in the probability variation per symbol determination table more than the symbol determination random number allocation for “special probability variation per” in the non-probability variation per symbol determination table. As a big hit game mode in the probability variation game, the special type big hit game can be made more frequent. As a result, it is possible to give the player a stronger impression that the game state has been switched to a new gaming state by the first hit. In addition, a big hit is likely to occur in the probable state, and since the big hit mode will be performed in a special mode in most cases, the impression that it has been switched to the gaming state will be stronger even more Can be given. In addition, whether or not the probability change state is directly related to the probability of occurrence of a big hit, and thus directly related to the number of game balls to be paid out, so if you try to increase the probability of occurrence of special probability change, you will pay out game balls It acts in the direction that the number increases. However, as described above, if the probability variation set in the winning symbol determination table is changed to the special probability variation, the probability of occurrence of the probability variation state does not change. For this reason, it is possible to easily increase the ratio to be performed in a special manner in the big hit game without substantially affecting the number of game balls to be paid out.
