Description

  The present invention relates to a gaming machine, and more particularly, to a so-called seven machine, a winged article, a right article, an arrangement ball or the like.

  There are various types of conventional ball game machines such as a so-called seven machine, a right item, or an arrangement ball. Among these, when the game ball wins or passes through the start winning opening, the seven machine displays the special symbol on the variable display device in a variable manner. When the display state of the variable display device becomes a big hit in a specific manner, for example, after a reach display, a combination of special symbols such as “7, 7, 7” is a combination of special symbols When stopped at the same time, it is configured to give interest to the player. Specifically, a special winning opening of a specific winning opening is opened, and a large amount of winning balls are paid out by allowing a game ball to be awarded to the special winning opening. The opened big prize opening is once closed when a predetermined number of game balls win or a predetermined time elapses, but the game ball passes through a specific area formed in the big prize opening during the opening. If so, it is opened again, and the opening and closing operations are repeated up to 16 times (so-called special game).

Depending on the special symbol (hit symbol) at the time of the big hit, there is a model to which a high probability gaming state (so-called probability variation state) is given that increases the probability of a big hit in the normal game after the special game ends (for example, patent literature) 1). For example, when the winning symbol is “7, 7, 7”, “3, 3, 3”, the high probability gaming state is given. In the high probability gaming state, for example, when the winning symbol is “2, 2, 2”, “8, 8, 8”, the game is configured to return to the low probability gaming state.
JP-A-7-613

However, at the present time, many models have the same specifications, and there has been a problem that it is not possible to provide gameability that further impacts the player.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can realize gaming properties not found in conventional gaming machines.

  Another object of the present invention is to achieve the above-mentioned object and to have a gameability that there is a possibility of shifting to the other variable state without performing the variable display for a predetermined number of times, and when to shift to the other variable state. The goal is to realize a game that is unknown.

Another object of the present invention is to make it possible to recover the “right to play a game with high probability” lost in one fluctuation state while achieving the above object in the other fluctuation state.
Another object of the present invention is to allow a player to play a game regardless of whether the gaming machine is in a favorable fluctuation state or an unfavorable fluctuation state for the player while achieving the object.

In order to achieve the above object, in the invention described in claim 1, the game board is provided with a first special symbol display unit and a second special symbol display unit, and the first special symbol display unit has a first special symbol, In the second special symbol display section, the second special symbol can be variably displayed. Then, when a game ball wins a winning opening provided on the same game board, a determination is made based on a random number value acquired at the time of winning. In addition, when a first variation state in which the first special symbol is varied and a second variation state in which the second special symbol is varied are set, and the game ball wins the starting opening It is determined whether the first fluctuation state or the second fluctuation state. Then, when the game ball wins the starting opening, according to the determination result about the changing state, either one of the first special symbol and the second special symbol is displayed in a variable manner for a predetermined period, and is stopped and displayed based on the result of the determination of success / failure. When a predetermined specific symbol is displayed, a privilege is granted to the player from the privilege granting means.

There are two types of probabilities that the first special symbol will be a specific symbol, and two types of probabilities that the second special symbol will be a specific symbol are prepared.
In the first variation state, when a predetermined first game condition is established, the second variation state is established. In the second variation state, when a predetermined second game condition is established, the first variation state is established. Thus, the game state transition means shifts the variation state.
In addition, when the first game condition is established and the transition is made from the first variation state to the second variation state, in the first variation state, the probability of success / failure determination is maintained in the state at the time of transition, and the second game condition is established. When transitioning from the second variation state to the first variation state, in the second gaming state, the probability of success / failure determination is maintained in the state at the time of transition. Then, in the state in which the first game condition is established and the state is shifted to the second fluctuation state in the first high probability state, the second game condition is determined by the probability determining means from the second high probability state to the second low probability state. When the second game condition is satisfied, the game in the first high probability state is started.

  According to the gaming machine configured as described above, there are two kinds of special symbols, and any one of them changes when a game ball wins a specific winning opening. The two special symbols are displayed with specific probabilities of two types of high and low.

  When the first gaming condition is satisfied in the first variation state, the state shifts to the second variation state. When the second gaming condition is satisfied in the second variation state, the state shifts to the first variation state. It is a gaming machine that can realize unprecedented gaming properties, such as playing two gaming machines.

Moreover, according to the gaming machine configured in this way, even if the fluctuation state shifts, the jackpot probability before the shift is maintained. For example, when a transition is made from the first high probability state (that is, the first fluctuation state) to the second fluctuation state and then the first fluctuation state is returned, the first high probability state is maintained. In addition, when the second low probability state (that is, the second fluctuation state) is shifted to the first fluctuation state and then returned to the second fluctuation state, the second low probability state is maintained. Therefore, when the change state shifts, it is possible to give a sense of expectation that “it may be a high probability state”. If the player knows whether the probability after the transition is high or low, the game can continue until the transition is made (if the transition is in a high probability state) or triggered by the transition of the variable state This is a model that can give a player a material for determining whether to continue or finish a game, such as when a game is finished (when the transition is in a low probability state).

In addition, according to the gaming machine configured as described above, even if the second variation state becomes the second low probability state, the variation state is shifted, and the transition destination first variation state is the first high probability state. Therefore, the privilege of the first high probability state can be given to the player.

The gaming machine according to claim 2 is provided with a selecting means for lottery whether the first change state to a second variation state lottery result of "the second variation state" by the lottery means This is the first game condition. According to such a gaming machine, there is a possibility that a player who is playing a game in the first variation state can experience the second variation state without changing the predetermined number of times or waiting for a predetermined time to elapse. In addition, it is possible to have a gameability that it is not known when to shift to the second variation state. The lottery means also performs a lottery to determine whether or not to change from the second variation state to the first variation state, and shifts to the first variation state when a lottery result of “to the first variation state” is obtained. According to such a gaming machine, there is a possibility that a player who is playing a game in the second variation state can experience the first variation state without varying a predetermined number of times or waiting for a predetermined time to elapse. In addition, it is possible to have a gameability that it is not known when to shift to the first variation state.

According to the third aspect of the present invention, a pseudo-symbol display unit capable of variably displaying a plurality of types of pseudo-symbols is provided, and the pseudo-symbols correspond to the variable display of the first special symbol and the second special symbol. It is configured to display a variable. That is, the pseudo symbol is variably displayed corresponding to the first special symbol in the first variation state, and is variably displayed corresponding to the second special symbol in the second variation state.

When the first special symbol or the second special symbol becomes a specific symbol, the pseudo symbol becomes a predetermined special symbol, and the first special symbol display unit and the second special symbol display unit are changed to the pseudo symbol display unit. By using a smaller display area, the first special symbol and the second special symbol are configured to be more difficult to identify than the pseudo symbol.

  This makes it difficult (or does not know) whether the gaming machine is in the first fluctuation state or the second fluctuation state, so that a game is also played in the gaming machine in the first fluctuation state.

  As described above, according to the gaming machine of the present invention, it is possible to realize an unprecedented gaming property as if two gaming machines having different specifications are played by one gaming machine.

  In addition, it is possible to realize a gameability that there is a possibility of shifting to the other variation state without performing the variation display for a predetermined number of times, and a gameability that does not know when to shift to the other variation state.

  Also, it is possible to realize a gaming machine that can experience both of the fluctuating states without having to fluctuate a predetermined number of times or wait for a predetermined period of time, and has a gameability that it is not known when the fluctuating state shifts. It can also be made.

In addition, it is possible to have an unprecedented gameability that a “right to play a game with a high probability” lost in one change state can be recovered in the other change state.
In addition, it is possible for the player to play a game, that is, to make it difficult to stop the game, regardless of whether the gaming machine is in a fluctuation state that is advantageous or unfavorable for the player.

  Further, when the high probability state is maintained in one of the fluctuation states, the high probability state can be provided again by the transition of the fluctuation state even when the high probability state is terminated on the other side.

  Note that the symbol control unit 160 and the sound / lamp control unit 170 described above may be configured by the same circuit units as the main control unit 140 and the payout control unit 150. That is, a CPU that includes a main circuit portion and an input / output circuit portion and has a built-in ROM and RAM can also be used.

Next, the winning ball operation is executed in the following order.
The main control unit 140 transmits a predetermined number of award ball number data to the payout control unit 150 via the signal transmission path 500a in the order of detection as a command signal for which the payout control unit 150 is an operation command target. The number of unique prize balls is 6, 10, or 15 in the first embodiment. Specifically, 15 when the game ball passes the winning ball detection switch 318, 6 when the game ball passes the start opening winning detection switch 17s, and other cases (for example, the left and right lower winning holes 21, For example, when the passage of 22 passage detection switches 21 s and 22 s is detected, the number is 10 for example. The payout control unit 150 receives the prize ball number data from the main control unit 140 and operates the prize ball payout device 109 by transmitting a prize ball payout signal.

  Further, the main control unit 140 determines a gaming state based on the outputs of the various detection switches described above. Further, the main control unit 140 determines whether or not the game is successful based on the gaming state and reads data for performing screen display control in a symbol display mode corresponding to the determination content. For example, the main control unit 140 uses the detection results of the start opening winning detection switch 17s, the winning ball detection switch 318, etc., the acquired value of the special symbol success / failure determination random number, and the like to wait for a customer who is not playing a game. Also, a state in which a game is played but no start prize is won (variable preparation state), a state in which a start prize has been won, a special game state, and the like are also determined. In addition, when a start winning is detected, determination of success / failure is performed based on a random value described later, and for the display mode control such as change of special symbols (including reach display mode) or confirmation based on the determination result Data is read. This data is transmitted via the signal transmission paths 500a and 500b as a command signal for which the symbol control unit 160 is an operation command target.

  Next, jobs executed by the main control unit 140 will be described with reference to FIGS. FIG. 14 shows an example of a main job executed by the CPU 401 of the main control unit 140 based on a program stored in the ROM 482.

  First, the stack pointer is set to a predetermined address in the RAM 481 (S10), and it is determined whether or not the RAM clear switch 144 is operated (pressed) (S12). As a result, when the RAM clear switch 144 is operated, the RAM 481 is initialized (S800). On the other hand, when the RAM clear switch 144 is not operated, it is determined whether or not the backup flag is set (S15). As a result, when the backup flag is set, the “recovery processing for power interruption” shown in FIG. 16 is performed.

  Note that the gaming machine 1 according to the first embodiment performs processing when a power interruption occurs, as shown in the flowchart of FIG. 15, when a power interruption occurs due to a power failure or the like. First, the used register is saved in the RAM 481 (S630), and the value of the stack pointer is saved in the RAM 481 (S632). Then, the special winning opening solenoid 313 and the starting opening solenoid 17c are turned off (S634), and the polling processing time (for example, about 85 milliseconds) of the winning ball sensor is set (S636). The passage of the game ball is monitored by the sensor (S638). Next, when the polling processing time elapses (S640), a checksum (excluding checksum, backup flag, and stack area) of the RAM 481 used is created (S642), stored, and the backup flag is set in the RAM 481 ( S646). Then, access to the RAM 481 is prohibited (S648), and an infinite loop process prepares for power down. It is also possible to execute HALT processing or STOP processing instead of the unlimited loop processing.

  In the “return process” shown in FIG. 16, a checksum is calculated (S664), and it is determined whether or not it matches the checksum stored when the power is turned off (S666). As a result, if the checksums do not match, the RAM 481 is initialized (S800). On the other hand, if the checksums match, the stack pointer before power-off is restored (S668), the backup flag is cleared (S670), and a command for returning the sub-board to the state before power-off is transmitted. (S672). Then, each register is returned to the state before the power is turned off (S674), the permission / non-permission of interruption is returned to the state before the power is turned off (S676, S678), and the address is returned to the address before the power is turned off (S680). In the first embodiment, since a backup power supply for power interruption measures is added to the gaming machine 1, “information advantageous to the player” that occurred before the power failure even during a power failure in the pachinko hall, etc. Can be saved.

  Returning to FIG. 14, if it is determined in step S15 that the backup flag is not set, the initialization end is determined (S20). As a result, if the initialization has not ended, the initialization end determination in S20 is performed again after executing the initialization job (S190). Note that the initialization process of the RAM 481 is performed when the gaming machine 1 is turned on for the first time from the shipment state, when the RAM clear switch 144 is operated (pressed), when the backup flag is abnormal, and when the checksum is one. If you did not do it.

  On the other hand, when the initialization is completed, each job from the LED job (S30) to the switch job (S70) is executed. In the LED job (S30), the display pattern data of the normal symbol and the normal symbol unstarted count, the display pattern data of the special symbol unstarted count, and the like are output. In the constant speed random number job (S40), a special symbol success / failure random number memory, a general-purpose count memory, and the like of the RAM 481 described later are updated. In the non-constant speed random number job (S50), the initial value counter and the off-normal symbol random number memory (not shown) are updated. The general-purpose count memory (not shown) is used, for example, for creating values “0” to “255” for each interrupt, executing command jobs, and decoration jobs.

  In the voice job (S60), data related to music and voice is read, and in the switch job (S70), various detection switches are read. That is, various signals such as the left and right winning opening passing detection signals are taken into the main control unit 140 via the relay board 190, and various signals such as the firing stop detection signal, the touch detection signal, and the volume detection signal are sent to the payout terminal board 191. Via the frame controller 150. In addition, the main control unit 140 receives a start port winning detection signal from the start port winning detection switch 17s, and receives a winning ball detection signal and a normal symbol operation gate passage detection signal from the large winning device 31.

  Next, it is determined whether or not there is an abnormality in various switches such as a count detection switch, a count detection and a specific area passage detection switch (S80). As a result, if there is an abnormality (ball clogging or disconnection), an error job (S130) is executed.

  On the other hand, if there is no abnormality, a special symbol main job (S90) and a normal symbol job (S100) are executed. In the special symbol main job (S90), a job related to data necessary for the main control unit 140 and the symbol control unit 160 to operate in cooperation is executed. Further, in the normal symbol job (S100), the display pattern data of the normal symbol and the normal symbol unstarted number of times is read.

  Thereafter, the state of each flag is set in the backup memory (S140), and a prize ball signal job (S150), an information signal job (S160), a command job (S170), and a remaining time job (S180) are executed. In the prize ball signal job (S150), data relating to prize ball payout is read and output, and in the information signal job (S160), data necessary for outputting information to other control units is read. Further, in the command job (S170), a command for special symbol management or the like is output, and in the remaining time job (S180), a non-constant random number is called. The initial value random number is also updated in the remaining time job of S180.

  Next, the success / failure determination job executed in the series of the main job will be described with reference to the flowcharts of FIGS. FIG. 17 is a flowchart of the success / failure determination job, FIG. 18 is a flowchart of the change state transition process, and FIG. 19 is a flowchart of the detachment process. The success / failure determination job is executed at the time of starting winning, that is, when winning at the starting port 17 (starting winning). In these jobs, various memories stored in the built-in RAM 481 of the main control unit 140 shown in FIG. 16 are used.

  First, as shown in FIG. 17, it is determined whether or not there has been a start prize (S200). As a result, if there is no start prize, the process skips to S250 and confirms whether there is a hold. As a result, when there is no hold (when the number of holds is zero), the process returns to S200, and when there is a hold (when the number of holds is 1 to 4), the process proceeds to S255.

  On the other hand, if there is a start winning, it is determined whether or not the number of holds (number of unstarted times) exceeds a certain value (“3” in the first embodiment) (S210). If the number of reserves (the number of unstarted times) exceeds a certain value, the start winning is invalid and skips to S255. On the other hand, if the number of holdings (the number of unstarted times) does not exceed a certain value, the number of holdings stored in the special symbol holding number memory 481b is increased by 1 (S220).

  Next, a special symbol validity determination random number (hereinafter also referred to as a validity random number or a determination random number) is generated and read by the random number generation means for validity determination (S230). The validity random number generation means may use software or hardware. The read determination random number value is stored in a special symbol success / failure determination random number memory 481a (hereinafter also referred to as a determination random number memory) (S240). Here, it is assumed that the determination random number value is obtained from 300 integer values of 0 to 299. The determination random number memory 481a stores the read determination random number value in a time series of start winnings in a shift memory format.

  Next, the oldest first determination random number value stored from the determination random number memory 481a is read (S255), and a big hit number reading process for reading a big hit number (winning determination value) from the big hit number memory 482a in the ROM 482 is performed ( S260).

  The big hit number reading process is as shown in FIG. 21. First, it is determined whether or not the current flag is 1 (specifically 0). This flag indicates which of the first special symbol and the second special symbol is variably displayed when a game ball enters the start port 17. When the flag is 0, the first special symbol and the flag are In the case of 1, the second special symbol is changed (hereinafter referred to as a special symbol when the first special symbol and the second special symbol are not distinguished from each other. Or “2) Special symbols are changed” is also simply referred to as “using first (or second) special symbols”). Note that the initial value of the flag is 0.

  When the flag is 1, that is, when the second special symbol is changed (S700: YES), the process proceeds to S705 and it is determined whether or not the present is a high probability. In the case of high probability (S705: YES), the process proceeds to S715, and the high probability jackpot number for the second special symbol is read. The high-probability jackpot numbers are 5, 57, 107, 157, and 207, and all of these 5 are read and the process is terminated. On the other hand, if the probability is low (S705: NO), the process proceeds to S710, and the jackpot number for low probability of the second special symbol is read. The jackpot number for low probability is only 7, and “7” is read and this processing is terminated. Since the determination random number value is configured to be obtained from 300 integer values of 0 to 299, in the case of a high probability, the probability of being a big hit is 1/60 (= 5/300), a low probability In this case, the probability of a big hit is 1/300.

  On the other hand, when the flag is 0, that is, when the first special symbol is used (S700: NO), the process proceeds to S720 to determine whether or not the current probability is high. If the probability is high (S720: YES), the process proceeds to S725, and the high probability jackpot number of the first special symbol is read. As with the second special symbol, the high probability jackpot number is 5, 57, 107, 157, 207, and all of these 5 are read and the process is terminated. On the other hand, if the probability is low (S720: NO), the process proceeds to S730, and the jackpot number for low probability of the first special symbol is read. The jackpot number for low probability is only 7, and “7” is read and this processing is terminated. Since the determination random number value is obtained from 250 integer values from 0 to 249, in the case of a high probability, the probability of being a big hit is 1/50 (= 5/250), a low probability In this case, the probability of a big hit is 1/250. This jackpot number reading process corresponds to the probability determining means of the present invention.

  Returning to FIG. Then, it is determined whether or not the determined random number value matches the jackpot number (S265). In the case of high probability, the determination random number value is compared with all five jackpot numbers. If it matches one of them, it is determined as “match”. As a result, if the two match, the big hit determination is made, and the big hit processing is performed (S270).

  The outline of the jackpot process is a process of generating and reading a jackpot symbol determination random number (identification information determination random number), storing (1 in the first embodiment) in the determination result memory 481j, and ending. It has become.

  The special symbol determined by the jackpot symbol determination random number value is subjected to a variable display state on the liquid crystal display device 27 on the basis of the symbol image data stored in the ROM 163 of the symbol control unit 160, and in a predetermined arrangement mode. Is displayed. The liquid crystal display device 27 includes a first special symbol display area (first special symbol display unit) for variably displaying the first special symbol and a second special symbol display area (first special symbol display) for variably displaying the second special symbol. Part). The symbol image data is stored in the RAM 481 of the main control unit 140 as an identification information determination value in association with the jackpot symbol determination random number value, and the read jackpot symbol determination random number is compared with the identification information determination value. It is good also as what determines the symbol which stops by this.

  Furthermore, the reach display mode specified by the reach mode determination random number value is displayed in a predetermined reach mode after the variable display state based on the reach display mode image data stored in the ROM 163 of the symbol control unit 160. The In this case as well, the reach display mode image data is stored in the reach mode determination value memory 4811l of the RAM 481 of the main control unit 140 as a reach mode determination value in association with the reach mode determination random number value and read. The reach mode to be displayed may be determined by comparing the reach mode determination random number value with the reach mode determination value.

  Next, the detachment process (S310) will be described with reference to FIG. First, it is determined by a random number whether or not an outreach job is performed. Specifically, a reach mode determining random number is generated, read (S315), and the reach number stored in the reach number memory 481i is read (S320). If the reach mode determination random number and the reach number match, it becomes a missed reach job, and if it does not match, it becomes a normal missed job (S330).

  In the case of a miss reach job, at least two symbols to be aligned (for example, a left symbol and a right symbol among three-digit symbols) are determined using a miss reach symbol determination random number (S340). Or you may make it match the right design with it referring to the random number of the left design. The determined symbol is stored in the reach symbol number memory 481m (S350). Further, the out-of-line symbol is similarly determined by a random number (S360), and the determined random number value is stored in the out-of-line symbol number memory 481g (S370). Then, the determination result of “outgoing reach” (“2” in the first embodiment) is stored in the determination result memory 481j (S380).

  On the other hand, in the case of a normal off-job, each symbol (for example, left symbol, right symbol, middle symbol) is determined by random numbers, and the determined random number values are stored in the corresponding symbol symbol number memories 481e, 481f, 481g. (S390-S440). Also, the determination result “normally off” (“3” in the first embodiment) is stored in the determination result memory 481j (S450).

  Here, the change state transition process for switching the flag will be described with reference to FIG. This process is started every time the special symbol is changed. In this process, first, in S900, it is determined whether or not the current flag is 1. When the flag is 0, that is, in the first fluctuation state (S900: NO), the process proceeds to S910, and it is determined whether or not the counter is 500 or more. This “counter” is for counting the number of times the first special symbol or the second special symbol has changed. Here, since the flag is 0, it represents the number of times the first special symbol has changed. If the counter is 500 or more (S910: YES), the counter is reset (set to zero) in the subsequent S920, the flag is inverted (set the flag to 1 in this case) in S930, and the process is terminated. If the counter is less than 500 (S910: NO), this process ends.

  On the other hand, when the flag is 1, that is, in the second fluctuation state (S900: YES), the process proceeds to S940, and it is determined whether the counter is 300 or more. Here, the counter counts the number of times the second special symbol has changed. If the counter is 500 or more (S940: YES), the process proceeds to S920, the counter is reset, the flag is inverted in S930 (here, the flag is set to 0), and this process ends. If the counter is less than 300 (S940: NO), this process ends.

  This variation state transition process corresponds to the gaming state transition means of the present invention. When the first special symbol varies 300 times in the first variation state, the state transitions to the second variation state, and in the second variation state, the second special state. When the symbol fluctuates 500 times, the process shifts to the first variation state. The first special condition that the first special symbol varies 300 times corresponds to the first gaming condition of the present invention, and the second special symbol that varies 500 times corresponds to the second gaming condition of the present invention.

Next, an outline flow of the special symbol main job executed in the series of the main job will be described with reference to the flowchart of FIG.
First, in S500, it is determined whether or not the current flag is 1. When the flag is 1, that is, in a high probability state (S500: YES), the process proceeds to S502, and the variation of the second special symbol is started. When the flag is 0, that is, in a low probability state (S500: NO), the process proceeds to S505, and the variation of the first special symbol is started.

  Next, the determination result for each winning obtained in the success / failure determination job shown in FIGS. 17 to 19 is read from the determination result memory 481j (S510), and it is determined whether or not the determination result is a big hit determination (S520).

  As a result, in the case of the big hit determination (“1”), the reach mode determining value stored in the reach mode determining value memory 481l corresponding to the above-described reach mode determining random value is read (S580), and the big hit number ( The identification information determination value) is read from the jackpot number memory (determination value storage means) 482a (S600). Next, proceeding to S610, for example, the left symbol and the right symbol are aligned with the same symbol, and after a predetermined reach display mode, the middle symbol is aligned with the same symbol as the left symbol and the right symbol, and is stopped and displayed (S610). ).

  On the other hand, if it is not a big hit determination, it is determined whether or not it is a missed reach determination ("2") (S530). As a result, in the case of the detachment reach determination (“2”), the detachment symbol number is read from the aforementioned detachment symbol number memory 481m, and the detaching symbol number is read from the detaching symbol number memory 481g (S570). Then, a difference between the number of the outreach symbol number and the number of the out-of-interest symbol number (for example, the difference between the left symbol and the middle symbol) is calculated (S571). Determine (S572). For example, when the middle symbol is the symbol immediately before the left symbol and the difference is “−1”, one type is selected from a plurality of types (for example, three types) outliers (for example, a predetermined random number). Can be selected by acquisition) and read. Thereafter, for example, after the left symbol and the right symbol are aligned to the same symbol and subjected to a predetermined reach display mode, the middle symbol is stopped and displayed with a symbol different from the other symbols (S610).

  On the other hand, if it is not outlier reach determination, it is normal outage determination ("3") (S540), each out symbol number is read from outnumber memory 481e, 481f, 481g (S550), and each special symbol (for example, , The left symbol, the right symbol, and the middle symbol) are stopped and displayed at a timing shifted from each other (S560). Even in the case of normal deviation determination, the display mode is changed to various modes by “slip display” or the like. This is because the display mode image data is stored in a normal out display mode determination value memory (not shown) in the RAM 481 of the main control unit 140 as a normal out display mode determination value in association with the reach mode determination random number value. Another example is to determine the normal off mode to be displayed by comparing the read reach mode determining random number value with the normal off display mode determining value.

  When the big hit determination is made, the first or second special symbol is fixedly displayed on the liquid crystal display device 27 in a predetermined arrangement mode (for example, an arrangement mode of the same three-digit symbols of “7, 7, 7”), After that, a special game state (a big hit game state) in which a special game is executed is entered. In the special gaming state, first, the opening / closing plate 312 of the big winning device 31 is in an open state, so that the game ball can be easily received by the player in the big winning opening 311.

  In this special game state, the big winning device 31 is kept in the game ball receiving state until a predetermined end condition is satisfied. For example, when a predetermined time t1 (for example, 30 seconds) elapses or when a predetermined number n1 (for example, 10) of winning balls is detected by the winning ball detection switch 318, the end condition is satisfied, and the game ball receiving state Is ended once, and the opening / closing plate 312 is closed, and one round is completed. If a predetermined continuation condition (passing to a specific area not shown) is satisfied after a predetermined time t2 (for example, 0.5 seconds) has elapsed after the opening / closing plate 312 is closed, the opening / closing plate 312 is again opened. The big winning device 31 enters the game ball receiving state. It should be noted that the game ball receiving state in which the end condition is one round is continuously repeated up to a predetermined maximum number of continuous rounds (16 rounds in the first embodiment). Further, if the continuation condition is not satisfied when the end condition is satisfied, the special gaming state ends (so-called puncture) in that round.

  As described above, according to the gaming machine 1 described above, there are two kinds of special symbols, and when a game ball is won at the start port 17, either one of them changes. The probability that the first special symbol is a big hit is 1/50 when the probability is high and 1/250 when the probability is low, while the probability that the second special symbol is a big hit is 1/50 when the probability is high. 60, 1/300 when the probability is low. Thus, the first special symbol and the second special symbol have different probabilities of winning big hits. When the first special symbol changes 500 times, the second special symbol changes, and when the second special symbol changes 300 times, the first special symbol changes. Thus, it is a gaming machine that can realize an unprecedented gaming nature as if it were playing two gaming machines with different probabilities that a particular symbol was stopped and displayed. Moreover, since the condition for transition of the variation state is the number of variations of each special symbol described above, any variation state can be experienced as long as the special symbol is varied 500 times or 300 times, respectively.

  Here, the correspondence between the present embodiment and the configuration requirements of the present invention is shown. The liquid crystal display device 27 corresponds to the first special symbol display unit and the second special symbol display unit of the present invention, the start port 17 corresponds to the specific winning port of the present invention, and the special symbol main job is the special symbol variation of the present invention. It corresponds to the control means, and the big hit processing corresponds to the privilege giving means of the present invention.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and 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, the gaming machine 1 may be applied to other models (not to mention a model whose front view is different from that shown in FIG. 1, for example, an arranged ball pachinko machine).
Further, in the gaming machine 1 of the first embodiment, the big hit probability is different between the first fluctuation state and the second fluctuation state, but instead of (or in addition to) changing the big hit probability, other specifications are used. May be different. For example, the time for the blade piece to open may be changed between the first fluctuation state and the second fluctuation state. Further, the probability of changing from the low probability state to the high probability state (so-called probability variation entry rate) may be changed between the first variation state and the second variation state. For example, in the first variation state, when a privilege is granted, the probability becomes 1/10 with a high probability, and in the second variation state, when a privilege is granted, the probability becomes 9/10 with a high probability. It is. Even in this way, it is possible to realize an unprecedented gaming property as if two gaming machines having different specifications are played with one gaming machine.

  Further, in the gaming machine 1 of the first embodiment, the condition for shifting from the first variation state to the second variation state (first game condition) was to vary the first special symbol 500 times. You may make it the conditions of. In addition, the condition (second game condition) for shifting from the second variation state to the first variation state is to vary the second special symbol 300 times, but when the other conditions are established, the transition is made. Anyway.

  For example, when a predetermined time elapses in one fluctuation state, it may be shifted to the other fluctuation state, or when a predetermined number of game balls are used in one fluctuation state (the number of shot balls or the number of out balls is predetermined). When the number is reached, the other fluctuation state may be entered. Further, the first game condition (or second game condition) may be that the number of game balls borrowed with cash or a prepaid card reaches a predetermined number.

  When a predetermined character is displayed on the liquid crystal display device 27, the variation state may be shifted, or when a predetermined variation pattern is selected at the time of starting winning, the variation state may be shifted. In addition, a lottery may be performed at some opportunity (for example, a timing when a special symbol is variably displayed or a big hit is given), and the variation state may be shifted according to the lottery result. When the character display, the predetermined variation pattern, and the lottery are set to the first game condition or the second game condition, the certainty that the player can experience both variation states decreases, but on the other hand, when the variation state shifts It is possible to provide a gaming machine having a gaming property of not knowing. The lottery may not be performed after the privilege is granted, but may be performed when it is determined that the privilege is granted.

  An operation unit (for example, a button 8 (see FIG. 1)) may be provided, and the first game condition and / or the second game condition may be operated by the operation unit. According to such a gaming machine, if the operating unit is operated, the changing state shifts, so that the player can experience both changing states without changing a predetermined number of times or waiting for a predetermined time to elapse. . Note that the operation unit is not limited to mechanical devices such as buttons and levers, but also includes proximity sensors, infrared sensors, etc., and moves the player's `` fluctuating state '' by moving their hands close to or holding them. Including those that can convey the will to the gaming machine.

  There may be a plurality of first game conditions. In this case, the transition to the second fluctuation state may be performed when any one of the conditions is satisfied, or the transition to the second fluctuation state may be performed when all the conditions are both satisfied. In addition, when one condition is satisfied, it waits for the other condition to be satisfied (“one condition” may not be satisfied while waiting), and when the other condition is satisfied, the process shifts to the second fluctuation state. It is also good. Moreover, when there are three or more types of first game conditions, it is possible to shift to the second variation state when some of them are satisfied. The same applies when there are a plurality of second game conditions.

Another example of the game condition in which the change state shifts is shown in the second embodiment.
[Second Embodiment]
FIG. 23 shows a jackpot process having a function of shifting the fluctuation state. When this process is adopted, it is desirable to abolish the change state transition process shown in FIG. When this process is started, first, a jackpot symbol determination random number (identification information determination random number) is generated and read (S272). Note that the big hit symbol determination random number is read simultaneously with the reading of the determination random number at the time of starting winning, but may be read simultaneously with the determination of the hit determination or after a predetermined time after the determination of the hit determination.

  Next, in S274, it is determined whether or not the current flag is 1. When the flag is 0, that is, in the first fluctuation state (S274: NO), the process proceeds to S276, and it is determined whether or not the first special symbol has a low probability. If the first special symbol has a low probability (S276: YES), the process proceeds to S278 to determine whether or not the probability is high. When the probability is high (S278: YES), the process proceeds to S280, the flag is inverted (that is, the flag is set to 1), and the determination result “1” in the first embodiment is stored in the determination result memory. 481j (S300), and this process is terminated. When the current probability is high (S276: NO) or when the probability is not high (S278: NO), the process goes straight to S300 and the flag is not inverted.

  On the other hand, if the flag is 1, that is, the second variation state (S274: YES), the process proceeds to S282, and it is determined whether or not the second special symbol has a high probability. If the second special symbol has a high probability (S282: YES), the process proceeds to S284 to determine whether or not the probability is low. When the probability is low (S284: YES), the process proceeds to S286, the flag is inverted (that is, the flag is set to 0), the process proceeds to S300, and this process is terminated. If the current second special symbol has a low probability (S282: NO) or does not have a low probability (S284: NO), the process goes straight to S300 and the flag is not inverted.

  By executing such jackpot processing, when the jackpot probability becomes high in the first variation state, the gaming machine 1 enters the second variation state while maintaining the probability (high probability) in the first special symbol. Transition. When the probability becomes low in the second variation state, the probability (low probability) is returned to the first variation state while the second special symbol is held. At this time, since the high probability is held in the first special symbol, the player can now recover the “right to play with high probability” lost in the second fluctuation state in the first fluctuation state. It has become an unprecedented gaming machine. In addition, when the previous player holds the high probability state in the first variation state and stops the game of the gaming machine that has shifted to the second variation state, the subsequent player It is possible to obtain a high probability state held by the game. That is, in this gaming machine, when another person (another player) plays a game after playing to some extent, he / she (later player) can obtain more profit than he / she has won by lottery. Will have.

  However, in this gaming machine, since the second variation state is very advantageous for the player compared to the first variation state, if it is possible to easily determine which variation state the gaming machine 1 is, the first variation state There is a risk that no one will be able to play the gaming machine 1 in the game. In this case, it is preferable to use an embodiment as shown in FIG.

  In FIG. 22, the first special symbol and the second special symbol are displayed in the display area of the liquid crystal display device 27. The symbols 84a, 84b and 84c displayed at the approximate center of the liquid crystal display device 27 are pseudo symbols. The symbol 84c is transformed into a character symbol having identification information like the symbol 84a. The area where the pseudo symbol is displayed is referred to as a central area (pseudo symbol display portion) 86c. A first special symbol is displayed in the lower left region (first special symbol display portion) 86a of the liquid crystal display device 27, and a second special symbol is displayed in the lower right region (second special symbol display portion) 86b of the liquid crystal display device 27. Also in the present embodiment, the timing at which the first special symbol or the second special symbol starts / ends the variable display, and the condition for shifting from the state in which the first special symbol is variably displayed to the state in which the second special symbol is variably displayed. Control and the like are the same as in the first embodiment.

  In the gaming machine of the present invention, since the two special symbols, the first special symbol and the second special symbol, are provided, the special symbol that is variably displayed according to the gaming state is shifted. The pseudo symbol is displayed in a variable manner in synchronization with (in synchronization with) the variable display timings of both the first special symbol and the second special symbol. That is, the pseudo symbol also starts to fluctuate when the first (second) special symbol starts to fluctuate, and the fictitious symbol also stops to fluctuate (confirm) when the first (second) special symbol fluctuates. When the first (second) special symbol becomes a jackpot symbol (specific symbol) that generates a special gaming state, the pseudo symbol also becomes a jackpot symbol (specific symbol), and the first (second) special symbol When the symbol becomes a detached symbol, control is performed so that the pseudo symbol also becomes a detached symbol.

  In the present embodiment, the central region 86c is a larger region than the lower left region 86a and the lower right region 86b. This is a configuration for eliminating the need to change the player's viewpoint in accordance with the transition between the state in which the first special symbol is variably displayed and the state in which the second special symbol is variably displayed. That is, in this configuration, by providing the pseudo symbol, it is difficult for the player to determine which variation state is present, regardless of which of the first special symbol and the second special symbol is variably displayed. Has been.

  Specifically, in the first embodiment, the symbol arrangement of the first special symbol and the second special symbol in the case of the jackpot determination is exemplified as “7, 7, 7”, but in this embodiment, the special symbol is displayed. Since the display area is set to a small size, a part of the symbol (character) that can be expressed with a small number of digits such as “○ (per hit)” or “× (out)” or a combination of multiple color bars By using as a special symbol, it is possible to make it difficult for the player to identify which part is a real special symbol.

  As another method for making it difficult to identify the special symbol, the display area of the liquid crystal display device 27 shown in FIG. 3 is a pseudo symbol display unit 86f, and light emitting means (lamps and LEDs) provided on the left and right sides of the substrate 34 are respectively first. The special symbol display unit 86d and the second special symbol display unit 86e may be used. In this case, the first special symbol display unit 86d configures the first special symbol by a change in lighting pattern such as a change in color or lighting, extinguishing, or blinking. For example, the light emitting means 86d is lit in red when it comes off, blinking during fluctuation, and lit in blue when making a hit (in the hit judgment, the probability variation pattern in which the subsequent game is in a high probability state is green) The normal symbol that is in a low probability state can also be blue). The same applies to the second special symbol.

As described above, the pseudo symbols are mainly displayed on the large area by the liquid crystal display device 27 arranged in the approximate center of the game area, and the first special symbol and the second special symbol are displayed in the small area of the liquid crystal display device 27 or the game area. Sub-display on a small area at a side edge away from the liquid crystal display device 27 (a small display device (eg, a 7-segment display) provided separately from the liquid crystal display device 27 at the edge of the game area 11). By doing so, the player plays the game while paying attention only to the pseudo symbols. Then, it is difficult for the player to recognize the gaming state (whether the first variation state, the second variation state, the low probability gaming state, or the high probability gaming state), and the gaming state notification provided on the liquid crystal display device 27 The game state is notified by means (not shown). As an example of the gaming state notification, the background color of the display area of the liquid crystal display device 27 is changed (80% high probability gaming state in red, 50% high probability gaming state in blue, 20% high probability gaming state in white), For example, a predetermined character may appear (the probability of being in a high-probability gaming state differs depending on the type of character that appears). Of course, it can also indicate that the game state is 100% high probability game state or 100% low probability game state.
