Description

  The present invention relates to a ballistic gaming machine of the number cut type in which a privilege gaming state such as a high probability state ends on condition that the number of symbol fluctuations reaches a predetermined upper limit value.

  Conventionally, in a ball game machine, a symbol change of a symbol variation display game (symbol game) is performed on a display device when a game ball enters the start port, and the symbol is stopped in a predetermined manner. It becomes a big hit game state that is a special game state advantageous to the player, and after this big hit game is finished, it is shifted to a bonus game state that makes it easier to shift to a big hit game than the normal game state, and a predetermined number of symbol variations To be precise, there is a model in which the privilege gaming state is maintained until the symbol variation display game is executed. For example, after the big hit game ends, the probability change state (probably abbreviated as the probability change state) where the probability of the big hit lottery is higher than normal and the probability change state is met on condition that the number of symbol changes has reached a predetermined upper limit. Is a pachinko machine called a number-of-times cut type that ends (Patent Document 1 below).

  Actually, the probability variation state is not only the probability variation function that makes the jackpot lottery probability higher than usual, but also the time shortening function that shortens the variation time of special symbols and normal symbols and the opening time of the normal variation winning device (ordinary electric accessory) It is devised to make it easy to shift to jackpot game by activating the opening extension function to increase the number of times and setting it to “a state with probability change / short time / open extension”. For this reason, in the probability variation state, the time required to digest one special symbol variation display game, that is, the variation time of the special symbol is shortened compared to the normal gaming state, and the occurrence interval of the special symbol variation display game is reduced. Shorter than usual, special symbol variation display games will be quickly and quickly digested one after another. Therefore, the number-of-turns type ball game machine can generate a big hit game more quickly than usual during the probability change state, and by continuing to win the big hit lottery during the probability change state, in a short time It has the great appeal of being able to generate a large amount of balls.

  However, in the round-off type ball game machine, the bonus game state ends when the number of fluctuations in the bonus game state reaches the upper limit, so if you do not win consecutively, There is a problem that the state ends in no time and the player ends without having a sufficient expectation for the jackpot.

  As a solution, on the other hand, it is sufficient to set a longer symbol variation time during the probability variation state, but that is why a method such as using only the reach variation pattern during the probability variation state. Thus, if the variation time in the probabilistic variation state is set too long, the speed at which the ball is increased in the case of winning a big hit continuously decreases. On the other hand, in order to prevent a decrease in the rate of increase in the number of balls, it is only necessary to set the fluctuation time of the fluctuation pattern during the probability change state to be short. If the fluctuation time is set too short, as described above, the probabilistic state ends in a short time if the big win is not won, and the player lacks interest.

  Accordingly, an object of the present invention is to provide a bullet ball game machine that solves the above-described problems, suppresses a decrease in the rate of increase in ball speed, and does not give the player the impression that the privileged gaming state has ended without difficulty. There is to do.

  Further, a special symbol display device 38 configured by arranging 7-segment displays in three digits and a normal symbol display device 39 composed of two LEDs are provided near the upper right edge of the game area 3a. Further, in the game area 3a, there are a center ornament 48, a windmill 44 as a game ball drop direction changing member, a plurality of game nails (not shown), a plurality of light emitting devices (lamp, LED, etc .: not shown), and the like. It is arranged. Further, a lamp display device such as a decorative lamp 45 and an LED device are also provided in the vicinity of both end portions of the game board 3.

  Based on the winning of the game ball in the upper start opening 34 or the lower start opening 35, the main control unit 20 (see FIG. 3) performs a lottery (big win lottery and symbol lottery) related to the big hit by random number lottery. A special symbol is displayed on the special symbol display device 38 in accordance with the lottery result, a special symbol variation display game is started, and the result is displayed on the special symbol display device 38 after a predetermined time has elapsed. . At this time, the decorative symbols are variably displayed on the liquid crystal display device 36 in a form linked to the special symbol variation display game, and the decorative symbol variation display game is started. After the predetermined time has elapsed, the special symbol variation display device 38 is selected by lottery. The result is displayed, and the result is also displayed on the liquid crystal display device 36 by a decorative pattern.

  In the present embodiment, the liquid crystal display device 36 constitutes an image display device. However, the present invention is not limited to this, and as the image display device, a plasma display (PDP: Plasma Display Panel), an electronic paper display, an organic EL display (OELD: Organic). An electroluminescent display) may be used. The liquid crystal display device 36 displays various effects as images under the control of an effect control unit 24 (see FIG. 3) described later. That is, an effect reflecting the lottery result in the special symbol variation display game, that is, a decorative symbol is variably displayed, and the decorative symbol variation display game is displayed. Production, reach production and background production).

  Therefore, when the result of the special symbol variation display game on the special symbol display device 38 is “big hit”, the result of the decorative symbol variation display game on the liquid crystal display device 36 also reflects “big hit” appears. Is done. The special symbol display device 38 displays a special symbol indicating a big hit in a predetermined display mode (for example, two 7-segment displays are all in the “7” display state) and is displayed on the liquid crystal display device 36. , "Left", "Medium", "Right" display areas, a predetermined display mode (for example, each of "Left", "Middle", "Right") in which the decorative symbols reflect the above-mentioned lottery lottery results In the display area, the three decorative symbols are stopped and displayed at the display states “7”, “7”, and “7”.

  When the big hit is made, the special variable prize winning device solenoid 42a (see FIG. 3) is actuated to open the open door 42b, whereby the big prize opening 40 is controlled to open and close in a predetermined pattern, and the normal gaming state A big hit game is generated as a special game state that is more advantageous to the player. In the big hit game, the open door 42b is opened for a predetermined time (for example, 29 seconds) and the big winning opening 40 is opened, or until the predetermined number (for example, 9) of game balls has won, Is opened, and then a predetermined number of times (for example, maximum 15R (round)) such as the opening door 42b is closed for a predetermined time (for example, 2 seconds) and the special winning opening 40 is closed (round game). It is supposed to be repeated.

  The jackpot game is started after the symbol indicating the jackpot is confirmed and displayed in the symbol variation display game. When the big hit starts, the opening effect by the big hit start fanfare is first performed, and after the opening effect is finished, the round game in which the big winning opening 40 is opened is performed a plurality of times with the predetermined number of rounds as an upper limit. In addition, during a round game, a corresponding round effect is performed. Then, after the specified number of rounds is over, the ending effect by the big hit end fanfare is performed, and the big hit ends.

  In addition, based on the fact that the game ball has passed through the normal symbol start opening 37 of the gate, the main control unit 20 performs a lottery (auxiliary per lottery) related to the subsistence by random number lottery. In accordance with the lottery result, the normal symbol represented by the two LEDs 39 is variably displayed on the normal symbol display device 39, and the normal symbol variation display game is started. The stop display is made by a combination of lighting or a combination of both lighting. If the result of the normal symbol variation display game on the normal symbol display device 39 is “per assist”, the display part of the normal symbol display device 39 is in a predetermined pattern (for example, both of the two LEDs 39 are lit). Stop display.

  When the auxiliary hit is reached, the normal variation prize winning device solenoid 41a (see FIG. 3) for driving the left and right movable blade pieces 47 is activated, and the movable blade pieces 47 are formed in a reverse “C” shape. The lower start opening 35 is opened or expanded so that the game ball can easily flow in, and an auxiliary game state advantageous to the player (hereinafter referred to as “general power open game”) occurs. In this general electric open game, the movable wing piece 47 of the normal variation winning device 41 is opened for a predetermined time (for example, 0.2 seconds) and the lower start opening 35 is opened, or a predetermined number (for example, 5). ) Until the game ball has won the normal variation winning device 41 (lower start opening 35), and then the lower start opening 35 is opened, and then the movable wing piece 47 is closed for a predetermined time (for example, 0.5 seconds). The operation of closing 35 is repeated a predetermined number of times (for example, once).

  Also, when the game ball wins the lower start opening 35 during the above-mentioned open game, the special symbol variation display game is similarly performed, and the decorative symbol variation display game is performed accordingly. The game balls that have not won the winning holes are discharged from the game area 3a through the out holes 49.

  If there is a detection signal input from the special symbol start port sensor 34a, 35a or the normal symbol start port sensor 37a during the special symbol variation display game or the normal symbol variation display game, Based on the detection signal, start memory (so-called operation hold balls), which is data related to the start right for playing each variation display game, is stored up to a predetermined upper limit, except for those involved during variation display. Then, in order to make the starting memory number clear to the player, it is displayed as an image at an appropriate position of the pachinko gaming machine 1 or on the screen of the liquid crystal display device 36. Normally, the variation display game for each start memory is executed and controlled in the order in which the start memories are generated. In this embodiment, as the predetermined upper limit, up to four start memories for special symbols and normal symbols are stored in the RAM 203 (see FIG. 3) provided in the main control unit 20, and the variation of the special symbol or normal symbol is determined. Held as a count.

(1-1. Internal gaming state)
The pachinko gaming machine 1 according to the present embodiment has three types of game states: a normal game state, a big hit game state, and a privilege game state as internal game states (game states managed on the main control unit 20 side). It has been. First, in order to facilitate understanding of the present invention, functions (means) related to the occurrence of a gaming state will be described.

  The pachinko gaming machine 1 according to the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function, in which the main control unit 20 (main control CPU 201: refer to FIG. 3) serves as its function unit. There are two types, a probability changing function related to a special symbol (hereinafter referred to as “special symbol probability changing function”) and a probability changing function related to a normal symbol (hereinafter referred to as “normal symbol probability changing function”).

  The special symbol probability changing function changes the jackpot probability variation state (hereinafter referred to as “big hit probability variation”) by changing the lottery probability of big hit from a low probability (for example, 1/399) to a high probability (for example, 1 / 39.9). This is a function for generating a state. In a gaming state in which the special symbol probability changing function is operating, that is, in a big hit probability changing state, the big hit lottery probability is changed to a high probability state with a high probability, and the big hit is likely to occur. Therefore, it can be said that the gaming state expected by the player is a gaming state in which the special symbol probability changing function is operating.

  The normal symbol probability changing function is a function that changes the probability per lot for auxiliary assistance from a normal probability that is low probability (for example, 1/256) to a high probability (for example, 255/256) to generate an auxiliary chance probability variation state. . In the game state (probability change per assist) in which the normal symbol probability change function is operating, the lottery probability per auxiliary will change to a high probability and the sub-attendance is likely to occur. Thus, an operating rate improvement state is achieved in which the operating rate of the movable wing piece 47 per unit time is improved compared to the normal gaming state. In the pachinko gaming machine 1 of the present embodiment, the operation timing of the normal symbol probability changing function is synchronized with the activation timing of the special symbol short-time function described later, and the termination timing is also synchronized with the termination timing of the special symbol time-shortening function. It has become.

  Furthermore, the pachinko gaming machine 1 of the present embodiment has a function of shortening the variation time (hereinafter referred to as “time reduction”), which is functioned by the main control CPU 271. There are two types of time-shortening functions relating to special symbols (hereinafter referred to as “special symbol time-shortening functions”) and time-shortening functions relating to normal symbols (hereinafter referred to as “normal symbol time-shortening functions”).

  The special symbol time reduction function is a function for generating a special symbol time reduction state in which the variation time of the special symbol in the special symbol fluctuation display game is shortened. In the game state in which the special symbol time shortening function is in operation, the time of one special symbol variation display game, that is, the variation time of the special symbol (the time from when the special symbol starts to change until the final display) is average For example, in the case of time or reach loss variation, the time is reduced from 30 seconds (when the special symbol time reduction function is not in operation) to 5 seconds (when the special symbol time reduction function is in operation). In other words, the average variation time of the special symbol is shortened compared with the normal gaming state, and the lottery number improving state is improved in which the number of big hit lotteries per unit time is improved as compared with the normal gaming state.

  The normal symbol short-time function is a function for generating a normal symbol short-time state in which the variation time of the normal symbol in the normal symbol variation display game is shortened. Under the gaming state in which the normal symbol time reduction function is activated, the time of one normal symbol fluctuation display game (the time from when the normal symbol starts to change until it is fixedly displayed) is, for example, 10 seconds (normal symbol) The time-saving function is shortened to 1 second (when the normal symbol time-saving function is in operation), and the lottery frequency improving state is improved in which the number of lotteries per auxiliary time per unit time is higher than in the normal gaming state. In the pachinko gaming machine 1 of the present embodiment, the operation timing of the normal symbol time-shortening function is synchronized with the operation timing of the special symbol time-shortening function, and the termination timing is also synchronized with the termination timing of the special symbol time-shortening function. It has become.

  In addition, the pachinko gaming machine 1 according to the present embodiment has an open extension function in which the main control unit 20 serves as its function unit.

  The open extension function is a function of generating an open extension state in which the movable blade piece 47 of the normal variation winning device 41 is opened and the number of times of opening is extended. Under a gaming state (a big hit probability change state) in which the opening extension function is operating, the opening operation period of the movable wing piece 47 is extended from 0.2 seconds to 1.7 seconds, for example, and the opening / closing frequency is, for example, once (opened) The operating rate is improved two times (when the extended extension function is in operation) from when the extension function is not in operation), and the operating rate improvement state in which the operating rate of the movable wing piece 47 per unit time is improved compared to the normal gaming state; Become. In the pachinko gaming machine 1 of the present embodiment, the operation trigger for the opening extension function is synchronized with the operation trigger for the special symbol short-time function, and the termination trigger is also synchronized with the termination trigger for the special symbol short-time function. ing. Thus, under the gaming state in which the open extension function is in operation, the normal symbol probability changing function and the normal symbol time-shortening function are also in operation, so that a gaming state in which the operating rate of the movable wing piece 47 is remarkably improved occurs.

  The game state can be changed by operating one or more types of the functions described above. Here, in the present embodiment, the operation triggers of the normal symbol probability changing function, the normal symbol shortening function, and the open extension function are synchronized with the operation trigger of the special symbol shortening function. In the following, for convenience of explanation, the gaming state in which the special symbol probability changing function, the special symbol time shortening function, the normal symbol probability changing function, the normal symbol time shortening function, and the open extension function are referred to as “probability changing state (probability changing)”. A gaming state in which the special symbol probability changing function is removed from among the functions is referred to as a “short time state (short time)”, and a state in which none of the functions is in operation is referred to as a “normal gaming state (normal state or normal state)”.

(1-2. High base gaming state)
In the present embodiment, the functions related to the above normal symbols, that is, the normal symbol probability changing function, the normal symbol short-time function, and the open extension function are synchronized with the operation trigger of the special symbol short-time function, so the three functions are the same. It will work at the moment. However, when attention is paid to the normal symbol probability changing function, the normal symbol time-shortening function, and the open extension function, respectively, when at least one of these functions is activated, the operating rate of the movable blade piece 47 is improved. Since the operating rate is improved and the winning frequency to the lower start opening 35 is increased, the game condition is that the starting condition of the special symbol variation display game for deriving the big win lottery result is higher than the normal gaming state. It will shift to the “high base game state (starting condition improved state)”. As used herein, the “high base gaming state” refers to a gaming state when a function related to a normal symbol is operated as described above, and a function related to a special symbol, that is, a special symbol probability changing function and a special symbol time-saving function. It is different from the gaming state when one of them is activated.

  Focusing on the special symbol related functions individually, when the special symbol probability changing function is activated, a big hit is more likely to occur than the normal gaming state, that is, the winning probability of the big hit lottery is higher than the normal gaming state. When the special symbol short-time function is activated (when the big hit probability variation state is entered), the special symbol variation display game has a “special symbol short-time gaming state” in which the digestion time of the special symbol variation display game is faster than the normal gaming state. In this respect, it is distinguished from the “high base gaming state” in which the starting condition of the special symbol variation display game is higher than the normal gaming state.

  In the present embodiment, as an example of the “high base gaming state”, a gaming state provided with an open extension function that significantly improves the operating rate of the movable wing piece 47 is treated as a “high base gaming state”. The movable wing piece 47 of the normal variation winning device 41 corresponds to a state in which the open extension function is not provided under the “high base game state” in which the open extension function is provided (in this embodiment, “normal game state”). Compared to (Yes), the player operates in a high base gaming state that is advantageous to the player.

(1-3. Type of jackpot)
Next, jackpot types managed on the main control unit side will be described.

  In the pachinko gaming machine 1 according to the present embodiment, “15R probability variable big hit” is provided as a big hit type to be drawn in the special symbol variation display game. In the 15R probability variation jackpot, the number of round games (the number of times the large winning opening 40 is opened) is 15 rounds with the maximum specified number.

  In addition, after the big hit game is finished, a privilege game state is generated. Specifically, after the big hit game with the 15R probability variable big hit, the “probable change state” occurs until the symbol variation is performed a predetermined upper limit number of times (for example, 99 times) as the bonus game state. Here, since the opening extension function is given during the probability changing state, the gaming state is the “high base gaming state”. In addition, after the predetermined upper limit number of times is completed, the “probability change state” ends and shifts to the “normal state”, and the gaming machine of this embodiment gives the probability change state up to the predetermined upper limit number of times. The “ST machine” is equipped with a so-called frequency cut probability changing function.

  In this embodiment, only one type of 15R probability variation jackpot is provided, but if necessary, for example, a “15R non-probability variation jackpot” that does not trigger the special symbol probability variation function is additionally provided. After the big hit game with the 15R non-probable big hit, the “short time state” is generated as one of the bonus game states until the special symbol variation display game number of times is over a predetermined number of times (for example, 100 times). You can also At this time, since the open extension function is given during the short state, the gaming state becomes the “high base gaming state”.

  The effect control command from the main control unit 20 is transmitted to the effect control unit 24 by one-way communication. This is to prevent an illegal signal from an external goto action from being input to the main control unit 20 via the effect control unit 24.

(2-2. Production control unit 24)
The effect control unit 24 is equipped with a microprocessor incorporating an effect control CPU 241, an effect control ROM 242 storing a control program describing effect control procedures, effect data, and the like, an effect control RAM 243 in which a work area is formed, It is equipped with.

  Information on the gaming state is first required for a special symbol variation pattern based on the result of the jackpot lottery (whether it is a big hit or a loss), the current gaming state, the number of balls held for operation, a decorative symbol to be stopped based on the lottery result, etc. Basic information is transmitted from the main control unit 20 to the effect control unit 24 by an effect control command.

  On the effect control unit 24 side, an effect pattern corresponding to the effect scenario instructed by the effect control command sent from the main control unit 20 is determined by lottery from a number of effect patterns prepared in advance. A control signal instructing execution of the effect pattern is sent from the effect control unit 24 to the liquid crystal display device 36, the sound generator 46a, and the light display device 45a.

When these pieces of information are transmitted as valid, the mode (MODE) and the event (EVENT) Corresponding to each, a strobe signal is output. That is, when there is a command to be transmitted, the main control CPU 201 sets and outputs mode (MODE) information for transmitting the command to the effect control unit 24, and the first strobe signal after a predetermined time has elapsed from this setting. Is sent. Further, event (EVENT) information is set and output after the elapse of a predetermined time from the transmission of the strobe signal, and the second time of the strobe signal is transmitted after the elapse of the predetermined time from the setting. When the strobe signal is transmitted, the effect control CPU 241 generates an interrupt corresponding to the strobe signal, and receives a command by this interrupt processing. The strobe signal is controlled by the main control CPU 201 to be in an active state for a predetermined period during which the effect control CPU 241 can reliably receive a command.

<3. Processing on the main control side: FIGS. 4 to 14>
Next, processing contents on the main control unit 20 side will be described with reference to FIGS.

(3-1. Main control side main process: FIG. 4)
When the pachinko gaming machine 1 is powered on, a voltage is supplied to each control board by the power supply board 31, and the main control CPU 201 starts the main process on the main control side shown in FIG.

  In the main control side main process, first, a necessary initial setting process before starting the game operation is executed (step S101).

  Next, the state (ON / OFF) of the output signal of the RAM clear switch input through an input port (not shown) is confirmed. If the RAM clear switch is ON (step S102: YES), step S105 is performed. Then, the storage area is cleared as RAM initialization processing. However, if the RAM clear switch is not on (step S102: NO), it is determined whether or not the backup data stored in the backup RAM is valid when the power supply is interrupted next (step S103). When power is restored, the checksum is compared to check whether the backup data is valid.

  If the backup data is valid (step S103: YES), based on the backup data, the stack pointer before the power shutdown is restored, and the game restoration process necessary for starting the game from the processing state at the time of the power shutdown is performed. Execute (step S104), and proceed to step S107. If the backup data is not valid (step S103: NO), the stack pointer designation address is set in the stack pointer, and the RAM is initialized (step S105). With the initialization of the RAM, the RAM clear information is transmitted as an initialization command to each control board (step S106).

  Next, the CTC provided in the CPU is set (step S107). In this process, an initial value corresponding to 4 ms is set in the CTC time constant register so that a timer interrupt is periodically generated every 4 ms.

  After finishing the processing after the initial power-on in steps S101 to S107, as the normal operation processing (steps S108 to S112), the interrupt prohibition (step S108) and the interrupt permission (step S112) are repeated, In the meantime, various random number update processes are executed (steps S109 to S111).

  As a random number update process, after the process of S step 108, first, a random number value update process for a variation pattern is executed (step S109). In this variation pattern random value update process, the variation pattern random value using the special symbol variation pattern command for lottery is mainly updated.

  Subsequently, in the normal value per-symbol determination initial value random number update process (step S110) for executing the normal value per-symbol determination initial value random number update process (step S110) and the special symbol per-symbol determination initial value random number update process (step S111). , Update the random number used to change the initial value of the random number for normal symbol determination used in the normal symbol variation display game winning / failing lottery (for example, the process of updating the count value of the counter), and determine the initial value random number for special symbol determination In the update process (step S111), a random number used for changing the initial value of the special symbol per-determination random number used for the success / failure lottery of the special symbol variation display game is updated.

(3-2. Main control timer interrupt processing: Fig. 5)
FIG. 5 is a flowchart showing timer interrupt processing on the main control side that is activated by interruption every predetermined time (4 ms) in the main processing on the main control side.

  First, the main control CPU 201 executes a saving process (step S201) for saving a register to a predetermined stack area.

  Next, a periodic random number update process for periodically updating the random number related to each variable display game is executed (step S202). In the regular random number update process, various random numbers used for the success / failure lottery of the normal symbol variation display game and the special symbol variation display game are periodically updated.

  Next, a timer management process for managing and controlling a timer used for the game operation is executed (step S203). The timer values of various timers used for game machine control are updated here.

  Next, input management processing is executed (step S204). In this input management process, detection information from various sensors provided in the pachinko gaming machine 1 is read and stored in a register in itself (not shown). The information detected by the various sensors includes ON / OFF of switch signals output from winning detection switches such as the normal symbol starting port sensor 37a, the big winning port sensor 40a, the special symbol starting port sensors 34a and 35a, and the general winning port sensor 43a. Information.

  Next, error management processing is executed (step S205). In this error management process, the data read and stored in the input management process is grasped, the switch is checked, and an illegal winning is monitored, the game operation state is monitored, and the abnormality of the pachinko gaming machine 1 is monitored. To do.

  Next, prize ball management processing is executed (step S206). In the prize ball management process, control information (a prize ball payout control command for designating the number of prize balls) for causing the game ball payout device 19 to perform a payout operation is output.

  Next, normal symbol management processing is executed (step S207). In this normal symbol management process, a lottery determination in the normal symbol variation display game is executed, and the variation pattern of the normal symbol and the stop display mode of the normal symbol are determined based on the lottery result.

  Next, a normal variation winning device management process is executed (step S208). In the normal variation winning device management process, an excitation control signal for solenoid control is transmitted to the normal variation winning device solenoid 41a based on the result of the lottery determination in the normal symbol management processing (step S207), and the movable blade of the normal variation winning device 41 A series of operations of the piece 47 are controlled.

  Next, a special symbol management process is executed (step S209). In this special symbol management process, a big win lottery (big hit determination process) in the special symbol fluctuation display game is executed, and a special symbol fluctuation pattern and a special symbol stop display mode (stop special symbol) are determined based on the lottery result. To do. Details of the special symbol management process will be described later with reference to FIGS.

  Next, a special variable winning device management process is executed (step S210). In the special variable winning device management process, an excitation control signal for solenoid control is transmitted to the special variable winning device solenoid 42a on the basis of the result of the big hit winning lottery in the special symbol management processing (step S209). This is a process of controlling the opening and closing of the big winning opening 40 according to a predetermined pattern and controlling the execution of the game related to the big hit. Details of the special variable winning device management process will be described later with reference to FIGS.

  The main control CPU 201 executes the “LED management process” after the special variable winning device management process (step S211). This LED management process is a process of creating output data to the normal symbol display device 39 or the special symbol display device 38 or outputting a control signal based on the data according to the progress of the process.

  Further, the main control CPU 201 manages game island management of the game hall through an external concentration terminal board (not shown) such as a big hit occurrence, special symbol determination, normal symbol determination, and winning ball detection at the symbol start opening. An external terminal management process for outputting to the outside of the gaming machine such as a hall computer HC or an island lamp used in the game is performed (step S212).

  And after performing the process of step S202-step S212 as mentioned above, the contents of a register are restored (step S213) and a timer interruption process is complete | finished.

(3-3. Segmentation of probability variation state: Fig. 6)
FIG. 6 shows an outline of the division into sections of the number cut probability change state performed in the special symbol management process (FIG. 5, step S209).

  The main control unit 20 wins the special symbol variation display game in the normal state, and the big hit game is started. The big win game is ended by opening and closing the big winning opening for a predetermined number of rounds. When the big hit game is finished, the game state of the main control unit 20 is shifted to a privilege game state in which the transition to the big hit game is relatively easier than the big hit game state. As a representative example of the privilege gaming state, here, the special symbol probability changing function, the special symbol time shortening function, the normal symbol probability changing function, the normal symbol time shortening function, and the opening extension function are shifted to the “probability changing state”. This probability variation state is a “number cut probability variation state”, so-called “ST”. In the high probability state during ST, the winning probability of the internal lottery is changed higher (for example, changed to about 10 times) than in the normal gaming state (low probability / non-short-time state). This number cut probability change state ST is terminated when the number of symbol variations reaches a maximum of 99 times (shown as a total of 99 times in FIG. 6), and the game state of the main control unit 20 is normal. Returned to gaming state.

  In short, after the big hit game is over, the special figure probability change state flag is always turned on and the state changes to "probability change state" (high probability, short time, with open extension), and the probability change state is maintained until the special symbol changes 99 times. The

  In accordance with the present invention, the period during which the state is changed to the probability variation state is divided into the first half and the second half of the predetermined number of symbol variations, with the number of symbol variations, that is, the execution of the special symbol variation display game as a unit. In the case of the present embodiment, the predetermined number of symbol fluctuations divided into the first half and the second half is the 30th, and the first half of the symbol fluctuation up to the 30th time with this as the boundary is “probability variation A state (abbreviated as probability variation A)”. And the latter half section after that is distinguished as “probability variation B state (abbreviated as probability variation B)”. And the variation time of the special symbol at the time of non-winning in the first half section (probability variation A state) (the time from the start of the symbol variation to the stop) than the variation time of the symbol at the time of non-winning in the second half interval (probability variation B state) The fluctuation pattern is defined so as to be relatively short.

  In this way, the duration of the probabilistic state is divided into a front and back after a predetermined number of symbol variations (30th), and the symbol variation time in the first half section is defined to be relatively shorter than the symbol variation time in the second half section. On the other hand, in the first half section (probability variation A state) in which the symbol variation time is set relatively short (for example, 1 second), the special symbol variation display game is quickly digested every time. It is possible to increase the speed at which the ball hits during the jackpot. On the other hand, in the second half section (probability variation B state) in which the loss variation time of the special symbol is set to be relatively long, it is determined that the player is in the probability variation state over a certain period of time (for example, 2 to 12 seconds). It is possible to entertain the probabilistic state for a long time in the same way as the normal gaming state while making it clearly conscious.

(3-4. Variation pattern selection table: FIG. 7)
FIG. 7 shows the structure of a variation pattern selection table for determining the variation pattern in the above-mentioned normal gaming state, probability variation A state, probability variation B state in association with the symbol variation time, and is stored in the ROM 202.

  In this variation pattern selection table, the first and second intervals of the probability variation state are determined by the first variation pattern distribution code “01”, the second variation pattern distribution code “02”, and the third variation pattern distribution code “00”. In addition, the three states of the normal game state are divided, and the types of variation patterns to be distributed to the variation pattern distribution code categories and the selection ratio thereof are determined.

  That is, the variation pattern distribution codes “00”, “01”, and “02” classify the current gaming state into “normal”, “probability variation A”, and “probability variation B”. The pattern distribution code “00” is set when the second half of the probability variation game state ends, specifies a normal game state with a relatively low profit state, and the variation pattern distribution code “01” ends the jackpot game The first half section of the probability variation gaming state is specified at the time, and the second variation pattern distribution code “02” is set when the first half section of the probability variation gaming state ends, and identifies the second half section of the probability variation gaming state.

  As the types of fluctuation patterns, fluctuation patterns of “normal fluctuation (unreaching fluctuation without reach)” of 1 second, 2 seconds, 5 seconds, 8 seconds, and 12 seconds, and reach loss fluctuations of “reach loss 1” to “reach loss 10” , Fluctuation patterns of “1 per reach” to “15 per reach” are provided. Here, “winning (big hit)” means that the display result of the symbols on the display device is a combination of specific display modes determined in advance. “Reach” is a combination of “out of” display modes other than the “big hit” combination, and is already displayed at the stage where some of the display results of the variable display units are not yet derived and displayed. A state in which the display mode in which the result is derived and displayed satisfies a display condition that is a combination of specific display modes.

  Of the types of variation patterns described above, the variation pattern with the normal variation of 1 second is dedicated to the probability variation A, and the variation pattern with the normal variation of 2 seconds is dedicated to the probability variation B. Of the fluctuations per reach, the fluctuation pattern of “11 per reach” to “15 per reach” is a fluctuation pattern dedicated to probability variation A, and is a fluctuation pattern for so-called premium effects. This premium production variation pattern can be prepared as a variation pattern for immediate use without a reach. These variation patterns are appropriately distributed as belonging to the three game states “normal”, “probability variation A”, and “probability variation B” specified by the variation pattern distribution codes “00”, “01”, and “02”. It is done.

  The selection ratio of the variation pattern allocated to the three gaming states is shown in the variation pattern selection table of FIG. 7 by the numerical value when the whole is 239, and the variation pattern in which the cell in which the numerical value is not written is not selected. It is shown that. As can be seen from the figure, the selection ratios of the variation patterns distributed to the three gaming states described above are not only determined by the variation pattern distribution codes “00”, “01”, “02”, but also in the result mode of the winning / failing lottery. It differs depending on whether it is a “hit” or “losing” (ON / OFF of the big hit determination flag) and the number of held balls (hold 0 to hold 3), and by lottery according to the selection ratio defined in this variation pattern selection table Any one variation pattern is selected.

(3-4-1. Normal state: in the case of fluctuation pattern distribution code 00)
In the case of a loss in the normal state (variation pattern distribution code 00), the number of held balls is divided into “hold 0 or 1”, “hold 2”, “hold 3”, and the fluctuation time is mainly 12 seconds, 8 seconds, The selection destination of the fluctuation pattern of 5 seconds is determined. In other words, when the number of held balls is as small as “hold 0 or 1,” the fluctuation pattern of “normal fluctuation of 12 seconds” with the longest fluctuation time is selected at a rate of 215/239 for the purpose of setting the fluctuation time longer. Then, the variation pattern of reach loss 1 to reach loss 10 is selected at the remaining 24/239 ratio. When the number of held balls increases to “hold 2”, the fluctuation pattern of “normal fluctuation of 8 seconds”, which is the second longest fluctuation time at the rate of 225/239, is selected and the ratio of 2/239 The variation pattern of “normal variation of 12 seconds” is selected, and the variation pattern of “reach loss 1” to “reach loss 10” is selected at the remaining 12/239 ratio. And when the number of reserved balls increases to 3 on hold, in order to set the fluctuation time short, the ratio of 228/239, “normal fluctuation of 5 seconds” belonging to the short fluctuation time as a normal symbol fluctuation The fluctuation pattern is selected, the fluctuation pattern of “normal fluctuation of 8 seconds” is selected at a ratio of 1/239, and the fluctuation pattern of “reach loss 1” to “reach loss 10” is selected at the remaining ratio of 10/239 Is done.

  In the case of hitting in the normal state (fluctuation pattern distribution code 00), the selection destination of the variation pattern of “1 per reach” to “10 per reach” is set to 20/239 without adding too much weight to the selection ratio. Determine at a rate of ~ 30.

(3-4-2. Probability A state: In the case of the fluctuation pattern distribution code 01)
In the case of a loss in the probable variation A state (variation pattern distribution code 01), the variation of “normal variation of 1 second” with the shortest variation time regardless of whether the number of retained balls is “hold 0 to 3”. A pattern is selected. In the case of hitting the probability variation A state (variation pattern distribution code 01), the selection destination of variation patterns of “11 per reach” to “15 per reach” (for premium production) dedicated to probability variation A is made too small. Each is determined at a rate of 50-39 / 239 without adding light weight.

  Therefore, in this probability variation A state, when reach occurs, it becomes a big hit that generates a premium effect. All other cases are lost, and in the case of a loss, a normal change dedicated to probability variation A with a change time of 1 second is performed as a change display of the change, and the change in the normal game state (5 seconds, 8 seconds) 12 seconds), the symbol variation display is executed up to 30 times of execution, which is the first half section of the number cut probability change state.

(3-4-3. Probability B state: Fluctuation pattern distribution code 02)
In the case of a loss in the probabilistic B state (variation pattern distribution code 02), selection of a variation pattern with a variation time of 12 seconds and 2 seconds is mainly divided into “hold 0” and “hold 1-3”. Determine the destination. That is, when the number of held balls is “hold 0”, the longest variation time is set for all symbol variations, that is, at a ratio of 239/239 for the purpose of setting a long symbol variation time under the probability variation B state. A variation pattern of “12 seconds normal variation” is selected. This “normal variation of 12 seconds” is one of variation patterns common to the normal gaming state and the probability variation B state that may be selected in the normal gaming state. Therefore, when transitioning from the probability variation A state to the probability variation B state, when the game is lost due to the hold 0, the game state in which the symbol variation display is continued for the longest time of 12 seconds as in the normal gaming state. Become.

  Further, when the probability B state (fluctuation pattern distribution code 02) is lost, when the number of held balls is present, that is, when “holding 1 to 3”, the variation time is a high rate of 234/239. The short “2 seconds normal fluctuation” fluctuation pattern is selected, and the remaining five / 239 ratio fluctuation patterns of “Leach loss 6” to “Leach loss 10” are selected.

  Of these, the fluctuation time of “normal fluctuation of 2 seconds” is a value shorter than the fluctuation time of the symbol (5 seconds belonging to the short time of normal time) selected when the loss occurs under the hold 3 in the normal state. Therefore, it is possible to digest the probability changing game more quickly than the normal game. The fluctuation time of “normal fluctuation of 2 seconds” is longer than the symbol fluctuation time (1 second) in the fluctuation pattern dedicated to probability variation A selected at the time of loss in the probability variation A state. There is enough time to show symbol variation effects and notice effects that could not be generated under the A state. By making such an effect appear under the probability B state, it is possible to alleviate the feeling of frustration of the player due to continued loss of time, and to enhance the interest of the game for the player.

  The remaining “reach lose 6” to “reach lose 10” variation patterns at the time of loss in the probability B state (holds 1 to 3) are the normal game state and the probability change B state that may be selected in the normal game state. By including such a variation pattern in a selectable manner, the special symbol variation when there is a loss in the second half of the probability variation state with the number of retained balls (holdings 1-3) The display mode and effects of the display game can be increased, and the interest for the player can be enhanced.

  On the other hand, in the case of hitting the probability variation B state (variation pattern distribution code 02), a hit variation pattern common to the normal gaming state and the probability variation B state that may be selected in the normal gaming state is “per reach”. The variation pattern of “6” to “10 per reach” is determined at a rate of 39 to 50/239, with less weight on the selection rate. Therefore, by selectively displaying one of the plurality of variation patterns at the time of hitting, the display mode and effect of the special symbol variation display game can be increased even at the time of hitting, and the interest for the player can be increased. Can be increased.

(3-5. Special symbol management processing: Fig. 8)
Next, the special symbol management process in step S209 related to the big hit lottery will be described. FIG. 8 is a flowchart showing details of the special symbol management process. Here, first, a start port check process (step S301) is performed.

(3-5-1. Starting port check processing: FIG. 9)
In the start port check process, the number of reserved balls is added and various random numbers are acquired on condition that the number of reserved balls is less than the upper limit.

  In FIG. 9, the main control CPU 201 first confirms whether or not a winning ball is detected at the upper start port 34 or the lower start port 35 (step S311). When a winning ball is detected (step S311: YES), a special symbol start opening prize command indicating a win (upper start opening command for the upper start opening 34, lower start opening prize command for the lower start opening 35) is controlled. It transmits to the part 24 (step S312).

  Subsequently, the process proceeds to the process of step S313, and it is determined whether or not it is a case where the number of operation reserved balls of the special symbol is 4 or more (step S313). If the number of the special design operation hold balls (hereinafter referred to as “special design operation hold ball number”) is not 4 or more, that is, less than 4 (step S313: NO), the special design operation hold ball number is 1 Addition is performed (step S304), and the number-of-holds command corresponding to the increased number of balls to be held (here, the command is a pending addition command) is transmitted (step S315). This number-of-holds command is used when displaying the number of reserved balls for special symbols on the liquid crystal display device 36 (see steps S711 to S713 in FIG. 24). Next, the current values of the special symbol lottery random numbers (random numbers for determination per special symbol, special symbol stop symbol random number) and the random number for fluctuation pattern counter are acquired and stored in the acquired numerical value storage areas of the RAM 203 (steps). S316). Then, the process returns to step S301 in FIG. 8, and the process proceeds to step S302.

  When it is determined in step S311 that no winning ball has been detected (step S311: NO), or in step S303, the number of special symbol operation reserved balls is determined to be 4 or more (step S313: YES), Without performing the processes of steps S312 to S316, the process returns to step S301 of FIG. 8 and proceeds to the process of step S302.

  When the process proceeds to step S302 in FIG. 8, it is determined whether or not the big hit flag is set. If it is “big hit” (step S302: YES), it is not necessary to manage special symbols. After updating the data (step S309), the special symbol management process is terminated, and the process proceeds to the special variable winning device management process in step S210 of FIG.

  On the other hand, if it is determined in step S302 that it is not “big hit” (step S302: NO), the processing state (special symbol operation status) indicating the behavior of the special symbol is “special symbol standby (01H)” “special symbol waiting”. It is sequentially determined whether the symbol is changing (02H) or “special symbol is stopped (03H)” (step S303, step S305, step S307). If applicable, the process belonging to each processing state is performed. “Waiting for special symbol” means that the special symbol has not been changed and is waiting for the next change, and “Special symbol changing” means that the special symbol is currently changing. "Special symbol is stopped" indicates that the special symbol has been changed and stopped (during the special symbol confirmation time).

  Hereinafter, processing contents when the processing state is “special symbol waiting”, “special symbol changing”, and “special symbol stopping” will be described in order.

(3-5-2. Special symbol variation start processing: FIG. 10)
FIG. 10 shows the details of the special symbol variation start process which is shifted to the case where it is determined that the special symbol is waiting in the special symbol management process (FIG. 8) (step S303: YES).

  In the special symbol variation start process of FIG. 10, it is first determined whether or not the number of reserved balls (holding storage) for special symbols is zero (step S321). If the number of special symbol actuated balls is zero (step S321: YES), the special symbol is in a standby state and there is no reserved memory, and the fact that it has entered this state is reported to the production control unit 24 side. There is a need. For this reason, in this embodiment, a standby effect command is transmitted (step S334).

  However, if the standby effect command is transmitted without condition when the number of special symbol operation reserved balls is zero, the transmission of the standby effect command is repeated at a period of 4 ms while the number of special symbol operation reserved balls is zero. Unnecessary transmission occurs. Therefore, it is determined whether or not the standby effect command has not been transmitted (step S333). If the standby effect command has not been transmitted (step S333: YES), the standby effect command is transmitted to the effect control unit 24 (step S334). ) If the standby effect command has already been transmitted (step S333: NO), the special symbol management process is terminated without transmitting the standby effect command to the effect control unit 24.

  Here, it is determined whether or not a demonstration display condition for performing a demonstration effect is satisfied. If the demonstration display condition is satisfied, a demonstration display command may be transmitted to the effect control unit 24. In the gaming machine of the present embodiment, this determination is left to the effect control unit 24, and the special symbol management process is terminated without determining whether the demonstration display condition is satisfied.

  On the other hand, when the number of special symbol operation reservation balls is not zero (step S321: NO), 1 is subtracted from the number of special symbol operation reservation balls (step S322), and the number of reservation commands (here, the reservation subtraction) corresponding to the decreased number of reservation balls Command) is transmitted (step S323).

  Next, it is determined whether or not the value of the probability variation counter that counts the number of symbol fluctuations (hereinafter referred to as “probability variation number”) until the end of the entire interval (first half interval and second half interval) in the probability variation state is zero. (Step S324). Here, the “number of times of probability change” is a predetermined upper limit number of times that the probability variation state is ended with respect to the number of times of execution of the symbol variation display, and “99 times” is set here. If the value of the probability variation counter is not zero (step S324: YES), that is, if the number of symbol variations digested during the probability variation state has not yet reached the upper limit of 99, the remaining variation count (hereinafter referred to as “the remaining probability variation count”). "Remaining certain variation count command" is transmitted (step S325). Thereby, it becomes possible to grasp the remaining number of fluctuations until the probability variation state ends and to notify the player. When the value of the probability variation counter is zero (step S324: NO), the process proceeds to step S326 without transmitting the remaining probability variation command.

  Next, it is determined whether or not the value of the probability variation A number counter that counts the number of symbol fluctuations (hereinafter referred to as “probability variation A number”) until the first half of the probability variation state (probability variation A state) ends is zero ( Step S326). Here, “the number of times of probability variation A” is a predetermined number of times that the first half section is terminated under the state of probability variation with respect to the number of times the symbol variation display is executed, and “30 times” is defined here. If the value of the probability variation A count counter is not zero (step S326: YES), that is, if the number of symbol variations in the probability variation A state has not yet reached the predetermined number of 30, the remaining number of variations that the probability variation A state continues ( (Hereinafter referred to as “remaining probability variation A count”) is transmitted (step S327).

  Next, the process proceeds to step S328, and a determination is made as to whether or not the random number value acquired in step S316 (FIG. 9) belongs to the big hit determination value (big hit determination process) (step S328).

  Next, it progresses to step S329, the stop symbol random number value for special symbols acquired by step S316 (FIG. 9) is determined, and a stop symbol (special symbol stop symbol) is determined (step S329). In the case of this embodiment, this special symbol stop symbol is transmitted as the content of a special symbol designation command described later, and is used to specify the type of decorative symbol. The special symbol stop symbol determined in this process is a big hit It can also be used to define a mode (for example, a round background or music during a big hit game).

(3-5-2-1. Special symbol variation pattern setting process: Fig. 11)
Next, a special symbol variation pattern setting process is executed (step S330).

  FIG. 11 shows the details of the special symbol variation pattern setting process. In this variation pattern setting process, the variation pattern selection table of FIG. 7 is referred to, the variation pattern distribution codes 00, 01, 02, the big hit determination flag ON, OFF, and the number of reserved balls (hold 0 to hold 3). In response, one special symbol variation pattern is selectively determined by lottery (step S341). Thereby, the symbol variation time belonging to the special symbol variation pattern is also determined.

  Here, in the normal state (variation pattern distribution code 00), if the number of held balls is “hold 0 or 1”, “hold 2”, or “hold 3” at the time of a loss, the fluctuation time is “12 seconds”, “ The variation pattern of “8 seconds” and “5 seconds” is mainly selected, and the variation pattern of “1 per reach” to “10 per reach” is selected at the time of hit.

  During a total of 99 fluctuations during which the probability variation state continues, in the 30th symbol variation, which is the first half interval (probability variation A state), the symbol variation in the second half interval (probability variation B state) from the 31st to the 99th variation. A special symbol variation pattern with a relatively short symbol variation time is selected. That is, in the probability variation A state (variation pattern distribution code 01), the variation pattern of “normal variation of 1 second” with the shortest variation time is selected at the time of loss, and “reach per reach 11 dedicated to probability variation A” is selected at the time of hit. ”To“ 15 per reach ”variation pattern is selected. In the case of the probability variation B state (variation pattern distribution code 02), at the time of losing, the variation pattern of “12 seconds normal variation” is selected if the number of held balls is 0, and if the number of holdings 1 to 3, “2 seconds” A variation pattern of “normal variation” is selected, and a variation pattern of “6 per reach” to “10 per reach” is selected at the time of hitting.

  In this way, the variation pattern of the special symbol is determined, and as a result, the variation time corresponding to this variation pattern is determined. Therefore, after transmitting the variation pattern designation command to the effect control unit 24 (step S342), the variation time of this special symbol is set in the special symbol variation timer (step S343), and the special symbol variation pattern setting process is terminated.

  Proceeding to step 331 in FIG. 10, a special symbol designation command is transmitted to the effect control unit 24 (step S331). Therefore, both the special symbol variation pattern command (step S342) and the special symbol designation command (step S331) are transmitted to the effect control unit 24 as an effect control command. However, in the case of this embodiment, there is only one type of probability variation jackpot as the jackpot type, and it is not necessary to distinguish between probability variation symbols and non-probability variation symbols, so only the special symbol variation pattern command is transmitted to the effect control unit 24 and special. It is also possible to omit the transmission of the symbol designating command and draw by drawing on the production control unit 24 side.

  Next, the processing state (special symbol operation status) is switched to “special symbol variation (02H)” (step S332), and the special symbol variation start process is terminated. Then, the process returns to step 304 in FIG. 8 and proceeds to step 309 to update the display data. Thus, the special symbol management process is terminated, and the process shifts to the special variable winning device management process (FIG. 5).

(3-5-3. Special symbol variation processing: Fig. 12)
FIG. 12 shows the details of the special symbol changing process to be performed when it is determined that the special symbol is changing in the special symbol management process (FIG. 8) (step S305: YES).

  In the special symbol variation processing of FIG. 12, the special symbol variation timer is first monitored (step S351), and the special symbol variation time set in the special symbol variation timer in step S343 of FIG. 11 is awaited. (Step S351: NO). If the special symbol variation time has not elapsed, the special symbol variation processing is terminated without doing anything (step S351: NO). When the special symbol variation time has elapsed (step S351: YES), a “variation stop command” indicating that the variation of the special symbol is finished and stopped is transmitted to the effect control unit 24 (step S352). Then, the processing state (special symbol operation status) is switched to “special symbol stopping (03H)”, and a variation stop timer is set (step S353). As a result, the special symbol changing process is terminated, the process returns to step S308 in FIG. 8, the display data is updated (step S309), and the special symbol management process is terminated. Then, the process shifts to a special variable winning device management process (FIG. 5).

(3-5-4. Special symbol change suspension processing: FIG. 13)
FIG. 13 shows the details of the special symbol fluctuation suspension processing that is shifted to the case where the special symbol operation status is determined to be special symbol suspension (03H) (step S307: YES) in the special symbol management processing (FIG. 8).

  In the special symbol fluctuation stop process of FIG. 13, first, the variable stop time (for example, 0. 0) for displaying the stop symbol on the special symbol display device 38 set in the variable stop timer in step S353 (FIG. 12). Wait for 5 seconds to elapse (step S361: NO). That is, until the special symbol variation stop time elapses, the special symbol variation suspension processing is exited without doing anything.

(3-5-4-1. In normal state)
When the above-described time for fluctuation stop has elapsed (step S361: YES), the special symbol operation status is switched to “special symbol standby (01H)” (step S362). Then, it is determined whether the stop symbol is a big hit symbol or a lost symbol (step S363). If the stop symbol is a lost symbol (step S363: NO), the process proceeds to step S366, and it is determined whether or not the value of the probability variation counter is zero (step S366). In the case of the loss variation in the normal state, the value of the probability variation counter is zero, so the determination in step S366 is YES, and the special symbol variation suspension processing is exited. Returning to FIG. 8, the display data is updated (step S309), and the special symbol management process is terminated.

(3-5-4-2. In case of big hit)
If it is determined in step S363 that the symbol is a big hit symbol (step S363: YES), the “big hit flag” is set to ON (step S364). Further, the special symbol probability change state flag, the probability variation number counter, and the probability variation A number counter are cleared (step S365), and the special symbol variation suspension processing is terminated. Here, “special drawing” is an abbreviation for special symbol. Returning to FIG. 8, the display data is updated (step S309), and the special symbol management process is terminated.

  If the above-described big hit flag is set to ON, the determination in step S401 of the special variable winning device management process (FIG. 14) described later becomes YES, and a big hit game is given as a special game state advantageous to the player. At the end of the big hit game, “99” is set in the probability variation number counter, “30” is set in the probability variation A number counter, and the state designation by the variation pattern distribution code is switched to probability variation A (01) ( (See steps S457 to S459 in FIG. 19).

(3-5-4-3. Probability A state)
After the big hit game is over, the game shifts to a probability change state (privilege game state) and enters a probability change A state.

  If the value of the probability variation counter determined in step S366 is not zero (step S366: NO), that is, if the number of special symbol variations has not yet reached the upper limit, the probability variation state is entered after entering the probability variation state. Since it is continuing, the value of the probability variation counter is decremented by 1 (step S367), and it is determined whether or not the value of the probability variation counter after the subtraction is zero (step S368). In the present embodiment, the probability variation state is controlled such that the probability variation state ends with 99 variations. Therefore, since the value of the probability variation counter is not zero until the number of fluctuations is 99, the determination in step S368 is NO, and the process proceeds to step S371 to determine whether or not the value of the probability variation A number counter is zero. (Step S371). In the present embodiment, control is performed such that the state of probability variation A is reached up to 30 variations. Therefore, since the value of the probability variation A number counter does not become zero until the symbol variation of 30 times is executed, the process proceeds to step S372, and the value of the probability variation A number counter is decremented by 1 (step S372). It is determined whether or not the value of the A number counter has become zero (step S373). Until thirty symbol variations are executed, the determination in step S373 is NO, and the special symbol variation suspension process is exited. Returning to FIG. 8, the display data is updated (step S309), and the special symbol management process is terminated.

  Thereafter, every time symbol variation is executed once, the probability variation number counter is decremented by 1 in the special symbol variation suspension process of FIG. 13 (step S367), and the value of the probability variation A number counter is decremented by 1. (Step S372).

  When the value of the probability variation A number counter is subtracted 30 times in total, and the value of the probability variation A number counter after the subtraction becomes zero (step S373: YES), the state designation by the variation pattern distribution code is the probability variation B state (02 ) (Step S374), and the special symbol fluctuation suspension processing is exited. By the above process, the probability variation state (privilege game state) shifts from the probability variation A state (up to the 30th variation) to the probability variation B state (the 31st to 99th variation).

  The feature of the transition preparation process from the probability variation A state to the probability variation B state is only to switch the state designation by the variation pattern distribution code to the probability variation B state (02). For example, the state of the special figure certain variation state flag is The ON state (setting state) immediately before that is left as it is, and the probability variation state (privilege gaming state) is continued.

(3-5-4-4. Probability B state)
After entering the probability variation B state (the number of variations 31 to 99), each time the symbol variation is executed, the probability variation number counter is decremented by 1 (step S367). Since the value of the probability variation A count counter that manages the probability variation A state (up to the 30th variation) in the first half section is already zero, the determination in step S371 is YES, and the 31st to 99th variation counts in the second half section. Only one subtraction process of the probability variation counter that is managed is performed.

  When reaching the 99th variation, which is the final variation, the value of the probability variation counter is zero (YES in step S368) in the determination in step S368. Therefore, the special figure certain change state flag that was turned on in step S452 (FIG. 19) is returned to OFF (step S369), the state designation by the fluctuation pattern distribution code is returned to the normal state (00) (step S370), and the special symbol change Exit processing while stopped. Returning to FIG. 8, the display data is updated (step S309), and the special symbol management process is terminated.

(3-6. Special variation winning device management process: FIG. 14)
Returning to FIG. 5, following the special symbol management process (step S209), the special variable winning device management process is executed (step S210). This special variation winning device management process transmits an excitation control signal for solenoid control to the special variation winning device solenoid 42a based on the result of the big hit in the special symbol management processing (step S209). In this process, the winning opening 40 is controlled to open and close in accordance with a predetermined pattern, and a game related to a big hit (special game) is controlled.

  FIG. 14 shows the details of the special variable winning device management process. The main control CPU 201 first checks whether or not the big hit flag is set (ON) (step S401), and if it is not big hit (step S401: NO), this special variable winning device management process is performed without doing anything. Exit.

  When the big hit flag is set (ON) (step S401: YES), in order to control a series of operations of the special variable winning device 42 in the big hit game, the operation status of the electric accessory (special variable winning device) is Depending on which of 00H to 04H, processing belonging to each state (steps S403 to S407) is executed. When the operation status of the electric accessory is in the big hit start process (00H), the “big hit start process” (step S403) is performed, and when it is before the start of the special variable winning device operation (01H), the “special variable winning device operation start” starts. "Pre-processing" (step S404) is performed. If the special variable winning device is operating (02H), "special variable winning device is operating" (step S405) is performed, and the special variable winning device is not operating (03H). If there is, the “special variable prize winning device operation stop process” (step S406) is performed, and if the big hit end process is being performed (04H), the “big hit end process” (step S407) is performed. “Before starting the special variable prize-winning device” means that the operation of the special variable prize-winning device 42 is in a pre-start state and “special variable prize-winning device is operating” means that the special variable prize-winning device 42 is currently active. The fact that the special variable prize-winning device is being stopped indicates that the special variable prize-winning device 42 is currently stopped and is being continuously determined.

(3-6-1. Big hit start processing: FIG. 15)
FIG. 15 shows details of the jackpot start process (step S403) that is performed when the operation status of the electric accessory is in the process of starting the jackpot start (00H). In the jackpot start process, the accessory continuous operation device operation flag is turned ON to switch to “actual object continuous operation device in operation” (step S411). Here, the accessory continuous operation device refers to a functional unit for operating the special variable prize winning device 42 for one round continuously for a predetermined number of times. Next, the operation status of the electric accessory is switched to “Before starting the special variable winning device operation (01H)” (step S412). Then, the maximum number of rounds (for example, 15 times) and the opening effect time (for example, 10 seconds) are set (step S413). Here, the opening effect time is an interval period from the time when the stop timer time in step S325 has elapsed and the winning is confirmed until the operation of the special variable winning device 42 starts, and the period in which the opening effect is performed. Refers to a defined time span. Then, a jackpot start command is transmitted (step S414), and the jackpot start process is terminated.

(3-6-2. Preliminary processing for starting operation of special variable winning device: FIG. 16)
FIG. 16 shows the details of “special variable prize winning device operation start pre-processing” (step S404) that is performed when the electric accessory operating status is before the special variable prize winning device operation start (01H). In the special variable winning device operation pre-start process, it is determined whether or not a predetermined time (predetermined time before starting) has elapsed before the special winning opening 40 of the special variable winning device 42 is opened (step S421). Here, as the predetermined time before the start, in the first round, after the special symbol stop time of the variable stop timer in step S361 has passed and the winning is determined, the operation of the special variable prize winning device 42 starts. The opening production time (set in step S413 in FIG. 15) is monitored, but when passing through step S421 in the second round and thereafter, the interval time between rounds (the opening set in step S445 in FIG. 18). The previous interval time) is monitored.

  Until the predetermined time before the start elapses (step S421: NO), the special variable prize winning device operation pre-start process is exited without doing anything.

  When the predetermined time before the start has elapsed (step S421: YES), the special winning prize opening time (for example, 30 seconds) of the special variable prize winning device is set, and the special prize winning number counter is cleared to zero (step S422). ). Then, the operation status of the electric accessory is switched to “special variable winning device is operating (02H)” (step S423). Also, the operation pattern of the open / close door 42b is set according to the operation pattern of the special variable prize winning device 42, and based on this, an excitation control signal for solenoid control is transmitted to the special variable prize winning device solenoid 42a, and the open door 42b is operated to increase the size. The winning opening 40 is opened (step S424). Then, the special variable winning device operation start process is terminated.

(3-6-3. Special variable winning device operating process: FIG. 17)
FIG. 17 shows the details of the “special variable winning device operating process” (step S405) performed when the electric accessory operating status is operating the special variable winning device (02H). In the special variable winning device operating process, it is determined whether or not a winning ball to the special winning opening 40 of the special variable winning device is detected (step S431).

  When a winning ball is detected at the big winning opening 40 (step S431: YES), 1 is added to the “large winning opening winning number” (step S432), and a big winning opening winning command indicating this is added to the effect control unit. 24 (step S443). Then, the process proceeds to step S434. On the other hand, when a winning ball to the special winning opening 40 is not detected (step S431: NO), the process proceeds to step S434 without performing the above 1 addition processing (step S432) and transmission processing (step S433).

  When the processing proceeds to step S434, it is determined whether or not the number of large winning opening winnings after the addition has reached the maximum winning number (step S434). If the number of winning prizes has not reached the maximum winning number (step S434: NO), the time for which the preset winning opening 40 is open (the opening time of the big winning opening: 30 seconds set in step S422) is set. It is determined whether or not it has elapsed (step S435). Then, if the number of winning prizes does not reach the maximum winning number (step S434: NO) and the opening time of the big winning opening has not passed (step S435: NO), nothing is done and this special variable prize is won. The device management process ends.

  When the number of winning prizes reaches the maximum winning number (step S434: YES), the winning prize opening 40 is closed (step S436), and an interval command is transmitted (step S437). Then, the operation status of the electric accessory is switched to “Special variable prize winning device operation stopped (03H)”. Further, a remaining ball discharge time (for example, 2 seconds) for closing the special variable winning device for discharging the remaining balls is set (step S439).

  Even if the number of winning prizes reaches the maximum number of winnings, if the opening time for the big winnings has elapsed (step S435: YES), the winning prize opening 40 is closed at that time, and the electric equipment operation status Is switched to “Special floating prize winning device operation stopped (03H)”. Then, the special variable winning device operating process is terminated.

(3-6-4. Processing during suspension of special variable winning device operation: FIG. 18)
FIG. 18 shows the details of the “special variable prize winning device operation stop process” (step S406) performed when the operation status of the electric accessory is in the special variable winning device operation stoppage (03H). In the special variable prize winning device operation stop process, whether or not a predetermined time has elapsed since the big prize opening 40 was closed, that is, the closing time (2 seconds) set as the remaining ball discharge time in step S439 has elapsed. Whether or not (step S441). Until the remaining ball discharge time elapses (step S441: NO), nothing is done and the special variable prize winning device operation stop process is terminated.

  When the remaining ball discharge time has elapsed (step S441: YES), it is determined whether or not the number of operations (number of rounds) of the special variable winning device has reached a predetermined maximum number (here, 15 rounds) (step S442). . During the period up to 15 rounds, which is the maximum number of rounds (step S442: NO), the electric accessory operation status is switched to “Before starting the special variable winning device operation (01H)” (step S443). Then, 1 is added to the “special variable winning device operation count” (step S444), the current value of the number of rounds is updated, and the interval time before opening is set (step S445).

  When the maximum number of rounds has been reached in the determination in step S442 (step S442: YES), the electric accessory operation status is switched to “Big hit end processing (04H)” (step S446). Also, an ending effect time (for example, 5 seconds) is set (step S447), an ending effect command is transmitted (step S448), and the special variable prize winning device operation continuation determination process is terminated.

(3-6-5. Big hit end processing: FIG. 19)
FIG. 19 shows the details of the “hit winning process” (step S407) that is performed when the operation status of the electric accessory is the jackpot finishing process (04H). In this jackpot ending process, the ending effect time (5 seconds) set in step S447 has elapsed, that is, an interval section after the big winning opening 40 of the special variable winning device 42 in the final round is closed. It is determined whether or not (step S451). Until the ending effect time (5 seconds) elapses, nothing is done and the jackpot end process is exited (step S451: NO).

  On the other hand, when the ending effect time has elapsed (step S451: YES), the special figure certain change state flag is set to ON (step S452). Various settings at the end of the big hit are made (steps S453 to S459). That is, the jackpot end process corresponds to a game state transition preparation setting process for shifting the game state after the jackpot end to the probability change state (privilege game state). Specifically, the big hit flag is cleared (step S453), the accessory continuous operation device operation flag is turned OFF, and the operation is switched to “the accessory continuous operation device operation is stopped” (step S455), and the continuous number counter is cleared to zero. (Step S456). Further, the upper limit number “99” is set in the probability variation counter (step S457), and the variation number “30” as the rear end of the first half section is set in the probability variation A number counter (step S458), and the variation pattern distribution code is set. The state designation by is switched to the probability variation A state (01) (step S459).

  As other settings at the end of the big hit, settings necessary for the game state transition to the probability change state (privilege game state) are made (step S460). For example, normal symbol variation time shortening function setting, opening extension (setting of start condition and end condition of opening extension function), etc. are performed.

  Thereafter, the gaming state notification information is updated (step S461), and a gaming state command including the gaming state notification information is notified by notifying that the gaming state has shifted from the big hit state to the probable change state by a 7-segment display or a lamp. Is transmitted to the effect control unit 24. Then, a jackpot end command is transmitted (step S462), and the jackpot end processing ends.

  Returning to FIG. 5, the main control unit (main control CPU) 20 executes the “LED management process” after the special variable winning device management process (step S211). This LED management process is a process of creating output data to the normal symbol display device 39 or the special symbol display device 38 or outputting a control signal based on the data according to the progress of the process.

  Further, the main control unit (main control CPU) 20 sends signals indicating game states such as big hits, special symbol determination, normal symbol determination, winning ball detection at the symbol starting port, etc. An external terminal management process for outputting to the outside of the gaming machine such as a hall computer HC or an island lamp used for management of the gaming island is performed (step S212).

  And after performing the process of step S202-step S212 as mentioned above, the contents of a register are restored (step S213) and a timer interruption process is complete | finished. As a result, the processing returns from the interrupt processing routine to the main routine.

<4. Processing on the production control unit side: FIGS. 20 to 29>
Next, the process (FIGS. 20 to 29) on the production control unit side will be described.

(4-1. Production control side main process: FIG. 20)
When the gaming machine body is turned on and receives the power-on signal from the power supply board 31, the effect control unit 24 starts the effect control-side main process shown in FIG. In this effect control side main process, step S501 is performed as the first process after the power is turned on, and in other cases, steps S502 to S505 are performed as processes during normal operation.

  First, the effect control board 24 performs necessary initial settings before the start of the game operation as the first process after the power is turned on (step S501).

  Next, effect random number update processing is executed as processing during normal operation (step S502). In this effect random number update process, the random number value for effect lottery used mainly for selecting effect contents is regularly updated.

  Next, a command reception interrupt, a timer interrupt, an external INT, etc. are set in an interrupt enabled state (step S503), and then an interrupt disabled state is set (step S504). Then, the watchdog timer is cleared (step S505), and the process from step S503 to step S505 is executed in a loop process unless power interruption occurs.

(4-2. Command reception interrupt processing: FIG. 21)
Next, a command reception interrupt process that is executed when the effect control command from the main control unit 20 is received will be described.

  FIG. 21 is a flowchart showing command reception interrupt processing on the effect control side. This command reception interrupt process is a process that is executed with priority over an effect control side timer interrupt process (FIG. 22) described later when an effect control command is received from the main control unit 20.

  First, when the production control unit 24 receives the production control command from the main control unit 20, the production control unit 24 saves the register in a predetermined stack area (step S506), and then stores the control command in the predetermined area of the RAM 242. Perform (step S507) and restore the register (step S508). When various control commands sent from the main control unit 20 are received, an INT interrupt is generated, and when a control command is received in this reception interrupt process, it is stored in the command reception buffer.

(4-3. Production control side timer interrupt processing: FIG. 22)
FIG. 22 is a flowchart showing an effect control side timer interrupt process activated by interruption every predetermined time (2 ms) in the effect control side main process in the effect control board 24.

  First, the effect control CPU 241 executes a register saving process for saving the register to a predetermined stack area (step S601). Next, the watchdog timer that monitors the program abnormality is cleared, and the timer count is restarted (step S602). When the program is in a runaway state, the watchdog timer is timed up, the production CPU is automatically reset, and the runaway state is restored.

  Next, periodic update processing is performed (step S603). In this periodic update process, the initial value of the effect random number used for selecting the effect pattern and the contents of various timers necessary for the execution of the effect pattern are updated for each interrupt. A representative of the various timers is a timer that manages a time schedule relating to the production of effects. For example, the decorative symbol is variably displayed on the screen of the liquid crystal display device 36 which is substantially within the same period as the special symbol is varied on the special symbol display device 38 (within the special symbol variation period). Within the variation period (decoration pattern variation period), the production contents of what production pattern on the time axis, and with what time width, the decoration lamp 45, the speaker 46, and the liquid crystal display device 36 as production means. The time schedule of whether to make it appear by this etc. is time-controlled by this timer.

  Next, as an effect determination management process, a command analysis process (step S604) for determining an effect scenario based on the received control command is executed. In this command analysis process, whether or not a control command is received from the main control unit 20, that is, whether or not a control command is stored in the command reception buffer is monitored for each interrupt. For example, when a variation pattern command is received and the variation pattern designation code is stored in the reception buffer, in the command reception process, this variation pattern designation code is read out, and the corresponding representation is made with reference to the representation pattern table (not shown). Determine the pattern.

  Next, effect scenario update processing (step S605) is executed. In this effect scenario update process, based on the content of the effect scenario determined in the command analysis process (step S604), a control signal (image effect control signal) for operating the liquid crystal display device 36 is created, and a lamp or LED And a control signal (light emission control signal and sound control signal) for operating the speaker 46 is generated. Then, the created control signal is stored in a predetermined storage area of the RAM 243. Further, as the production scenario progresses, the image production control signal is output to the liquid crystal display device 36, and sound and LED control signals (light emission control signal and audio control signal) are matched to the image production. Also output.

  Following the processing in step S605, it is determined whether there is a sound control signal for sound data to be reproduced in the predetermined command storage area (step S606), and if there is a sound control signal for sound data to be reproduced. (Step S606: YES), the sound control signal of the sound LSI is input at the timing when the sound needs to be reproduced, and the sound is output from the speaker 46 through the sound source IC (step S607). Thereby, the sound effect according to the production scenario is generated from the speaker 46.

  Subsequently, LED output processing is executed (step S608). This LED output process receives this information when the audio control signal is transmitted to the sound LSI, and transmits the light emission control signal to the decoration lamp 45 or the LED in accordance with the corresponding effect, and turns it on or blinks to produce the effect by light. Is realized.

  Then, the saved contents of the register are restored (step S609), thereby terminating the effect control side timer interrupt process.

(4-3-1. Reception process of jackpot end command: FIG. 23)
FIGS. 23 to 29 show processing closely related to the bonus game that enters after the end of the jackpot game among the processing executed in the command analysis processing (step S604 in FIG. 22).

  FIG. 23 shows a process when the jackpot end command transmitted in step S462 of the jackpot end process (FIG. 19) is received. When this jackpot end command is received, the production scenario of the probability variation A state effect is set (step S701). When this effect scenario is set, the background displayed on the screen of the liquid crystal display device 36 is switched to the background for the probability variation A state, and the BGM for the probability variation A state flows from the speaker.

(4-3-2. Processing for receiving pending number command: FIG. 24)
FIG. 24 shows the hold number (addition) command transmitted in step S315 of the start opening check process (FIG. 9) or the hold number (subtraction) command transmitted in step S323 of the special symbol variation start process (FIG. 10). Processing when received is shown. When these hold number commands are received, the corresponding hold number is set (step S711), the hold display is updated (step S712), and the lottery for changing the color of the hold display as necessary A random number for use is set (step S713).

(4-3-3. Receiving processing of remaining probability variation A number command: FIG. 25)
FIG. 25 shows processing when the remaining probability variation A number command transmitted in step S327 of the special symbol variation start processing (FIG. 10) is received. When the remaining probability variation A count command is received, the effect control unit 24 sets the remaining variation count (probability variation A remaining count) at which the probability variation A state ends as shown in FIG. 25 (step S721).

(4-3-4. Receiving processing of remaining probability variation command: FIG. 26)
FIG. 26 shows a process when the remaining probability variation number command transmitted in step S325 of the special symbol variation start process (FIG. 10) is received. When the remaining probability variation command is received, the probability variation remaining number at which the probability variation state (privilege gaming state) ends is set as shown (step S731), and whether or not the remaining display numerical value is “9” or less, That is, it is determined whether or not the remaining probability variation number is 10 or less (step S732). Here, the “remaining display numerical value” is the remaining number of probability changes notified to the player by displaying numbers from “99” to “zero (last)” through the screen of the liquid crystal display device 36. This corresponds to the current value of the probability variation counter sequentially subtracted to zero. When the remaining display numerical value is larger than “9”, that is, when the number of remaining probable changes is 11 or more (step S732: NO), the command reception interrupt process is terminated without doing anything. However, when the remaining display numerical value is “9” or less, that is, when the number of remaining probable changes is 10 or less (step S732: YES), “9 remaining” is changed from “9 remaining” to “ The remaining number is sequentially counted down to “zero (last)” and notified to the player (step S733).

(4-3-5. Fluctuation pattern designation command reception processing: FIG. 27)
FIG. 27 shows the process when the variation pattern designation command transmitted in step S342 of the special symbol variation pattern setting process (FIG. 11) is received. When the change pattern designation command is received, an effect pattern corresponding to the change pattern designation command, that is, a change pattern for effect of the decorative design is set (step S741).

  That is, when a variation pattern designation command is received and the variation pattern designation code is stored in the reception buffer, the variation pattern designation code is read in the command reception process, and the corresponding production pattern is determined by referring to the production pattern table. To do. Here, the effect pattern table is a table in which at least a variation pattern designation code, a decoration pattern variation pattern, and a variation time are associated in advance as an effect pattern, and a plurality of effect patterns are associated with each variation pattern designation code. . By referring to this effect pattern table, an effect pattern corresponding to the variation pattern designation code is determined by selecting one of the effect pattern groups belonging to the variation pattern designation code by lottery.

(4-3-6. Symbol designating command reception processing: FIG. 28)
FIG. 28 shows a process when the symbol designation command transmitted in step S331 of the special symbol variation start process (FIG. 10) is received. When this symbol designating command is received, as shown in the figure, it is determined whether or not the remaining variation number of the decorative symbol (remaining certain variation A number) until the end of the probability variation A state is the last one (variation 30). Judgment is made (step S751). If the remaining number of fluctuations is 2 or more (step S751: NO), a decoration symbol that becomes a stop symbol due to the fluctuation is determined and an effect device (the liquid crystal display device 36 or a light display device 45a including a lamp and an LED). In addition, the announcement effect by the sound generator 46a including the speaker 46, a movable body, or the like) is determined by lottery (step S754).

  When the remaining number of fluctuations reaches the last one (30th time) (step S751: YES), the process proceeds to step S752, and it is determined whether the last one is a loss fluctuation (step S752). If it is not a loss variation (step S752: NO), the stop symbol and the notice effect by the effect device are determined by lottery (step S754). However, if the last one (30th) is a loss change (step S752: YES), the background switching effect is set without performing the notice effect (step S753). The transition to the probability B state is clearly notified by this background switching effect.

(4-3-7. Fluctuation Stop Command Reception Processing: FIG. 29)
FIG. 29 shows a process when the change stop command transmitted in step S352 of the special symbol changing process (FIG. 12) is received. When this change stop command is received, a change stop effect effect scenario is set (step S761). Next, when the remaining probability variation A count is 1 or more (step S762: NO), the process proceeds to step S764, confirms that the remaining probability variation count is not 1 (step S764: NO), and ends the processing.

  If the remaining probability variation A count is 1 (step S762: YES), an effect scenario of the probability variation B state effect is set (step S763). When this effect scenario is set, the background displayed on the screen of the liquid crystal display device 36 is switched to the background for the probability variation B state, and the BGM for the probability variation B state flows from the speaker. Then, it is checked whether or not the remaining probability variation number is 1 (step S764). If the remaining probability variation number is not 1 (step S764: NO), this process is terminated as it is. However, when the remaining probability variation number is 1 (step S764: YES), the effect scenario of the normal state effect is set (step S765), and the process ends.

  In this embodiment, when the symbol variation is stopped, that is, when the variation stop command is received, the production states such as the stop production, the probability variation B state production, and the normal state production are set (steps S761 to S765). The state setting may be performed at the start of symbol variation.

<5. Specific example: FIG. 30>
Next, with reference to FIG. 30, a specific example of the above-described number-of-times switching probability change game will be described. In order to facilitate understanding, a case where the probability variation state (privilege game state) ends without unfortunately winning a big hit for 99 symbol variations is handled here.

(Time t1)
In FIG. 30, time t1 indicates the time when the big hit game ends. Here, the main control unit 20 switches the electric accessory operation status to “big hit end process (04H)” and sets the ending effect time (for example, 5 seconds) in the special variable prize winning device operation stop process shown in FIG. Then, an ending effect command is transmitted (steps S446 to S448).

  Next, in the big hit end processing shown in FIG. 19, the main control unit 20 turns on the special figure probability changing state flag after the end of the ending effect time (5 seconds) (step S452), and clears the big hit middle flag (step S453). ), The accessory continuous actuating device operation flag is turned OFF (step S454), it is switched to “Big hit start processing (00H)” (step S455), and the continuous number counter is cleared to zero (step S456). In addition, the initial setting value “99” is set in the probability variation counter (step S457), and the initial setting value “30” is set in the probability variation A number counter (step S458). Switch to (01) (step S459). Then, a jackpot end command is transmitted (step S462).

  As described above, as shown in FIG. 30, the main control unit 20 side enters the “probability change A state”, and the effect control unit 24 side displays the “probability change A state effect” on the effect device.

(Time t2)
Thereafter, a game ball wins the special symbol start opening 34 or 35, and in the start opening check process of FIG. 9, the number of held balls is incremented by 1 and a hold addition command is transmitted (FIG. 9, steps S313 to S314). The effect control unit 24 receives this, and the hold count display is updated (FIG. 24, steps S711 to S713). In this starting port check process, a random number for special symbol lottery (random number value for special symbol determination, random number for special symbol stop) and a random number value for variation pattern are acquired (FIG. 9, step S316).

  Next, at time t2, the number of held balls is decremented by 1, and a hold subtraction command is transmitted (FIG. 10, steps S322 to S323). The effect control unit 24 receives this hold subtraction command, and the hold number display is updated (FIG. 24, steps S711 to S713).

  Next, a “remaining probability variation number command” is transmitted for the remaining probability variation number (initial value is 99) at which the entire period of the probability variation state ends (FIG. 10, step S325). In addition, a “remaining probability variation A count command” is transmitted for the remaining probability variation A count (initial value is 30) in which the first half of the probability variation state (probability variation A state) ends (FIG. 10, step S327). The effect control unit 24 receives the remaining probability variation number command and the remaining probability variation number command (step S721 in FIG. 25, step S731 in FIG. 26). Thereby, the production control unit 24 can grasp the remaining probability variation number and the remaining probability variation number A until the probability variation state ends, and can notify the player if necessary (FIG. 26). Steps S732 to S733).

  Next, in step S341 of the special symbol variation pattern setting process (FIG. 11), referring to the variation pattern selection table in FIG. 7, one variation pattern is selected according to the variation pattern distribution code, the jackpot determination flag, and the number of reserved balls. decide. Here, it is assumed that the probability variation A state (variation pattern distribution code 01) and the time of losing are assumed. Therefore, according to the variation pattern selection table, the variation pattern of “normal variation of 1 second” is selected at a rate of 100%. The variation pattern designation command of “normal variation of 1 second” is transmitted to the effect control unit 24 (step S342), and “1 second” is set as the symbol variation time in the special symbol variation timer (step S343). .

  When receiving the variation pattern designation command of “normal variation of 1 second”, the effect control unit 24 sets the variation pattern of the decorative symbol corresponding to the command (step S741). On the screen of the liquid crystal display device 36, the decorative design changes the design for the design change time “1 second”. The time length of this symbol variation time “1 second” is a time (with time reduction function) shorter than the symbol variation time (5 seconds to 12 seconds) of normal variation (unreaching variation without reach) performed under normal conditions. In addition, it is shorter than the fluctuation time of the symbol fluctuation in which the remaining 69 times under the probability variation B state are performed (2 seconds in the case of no reach). Therefore, 30 symbol variations under the probability variation A state are executed in a short time of “1 second” each time. Of course, when a loss or a big hit occurs after reaching, a longer variation time is set according to the variation pattern selection table of FIG.

  Next, a special symbol designation command is transmitted to the effect control unit 24 for the stop symbol (special symbol stop symbol) determined in step S329 of the special symbol variation start process (FIG. 10) (step S331). When receiving the symbol designation command, the effect control unit 24 proceeds from step S751 to step S754 in the process of FIG. 28, determines the stop symbol (decoration symbol) and the notice effect of the change by lottery (step S754), This is displayed on the liquid crystal display device 36. This continues until the 29th fluctuation.

(Time t3)
When the symbol variation time “1 second” elapses, the determination in step S351 of the special symbol variation process (FIG. 12) is YES, and the “variation stop command” is transmitted to the effect control unit 24 (step S352). When this change stop command is received, the effect control unit 24 sets the stop effect (step S761) and causes the corresponding stop effect to appear.

  Next, in step S353 of the special symbol changing process (FIG. 12), the special symbol operation status is switched to “special symbol stopped (03H)”, and the variable stop timer is set to “0.5 seconds” (step S353).

  When the timer time “0.5 seconds” for fluctuation stop has elapsed, the special symbol movement status is switched to “special symbol standby (01H)” in the special symbol fluctuation stop process (FIG. 13) (step S362). . Here, since the case where the stop symbol does not coincide with the jackpot symbol is handled (NO in step S363), the program proceeds from step S363 to step S366. Here, since 99 is set in the probability variation counter, the determination in step S366 is NO and the value of the probability variation counter is decremented by 1 (step S367). Since the value of the probability variation counter after subtraction is “98” and is not yet zero, the process proceeds from step S368 to step S371, and it is determined whether or not the value of the probability variation A number counter is zero (step S371). Since the value of the probability variation A number counter remains the initial value “30” and is not yet zero (step S371: NO), the process proceeds to step S372, and 1 is subtracted from the value of the probability variation A number counter (step S372). Since the value of the probability variation A count counter after subtraction is “29” and not zero (step S373: NO), the special symbol variation suspension processing is performed while maintaining the designated state (probability variation A state) of the variation pattern distribution code 01. Exit.

(Time t3 to t4)
The same process as in the case of the first symbol variation described above is repeated until the 29th variation.

(Time t4)
When the number of fluctuations reaches the 30th (the remaining number of fluctuations in the probability variation A state is one), in the symbol designation command reception process of FIG. 28, the determination in step S751 is YES, and the process proceeds to step S752, where the last one is It is determined whether or not there is a loss variation (step S752). Here, a case where the symbol variation of each time is a loss variation is handled, and since the last one (30th) is also a loss variation, the process proceeds from step S752 to step S753, and a background switching effect is set (step S753). The background on the screen of the liquid crystal display device 36 is switched. Thereby, the player is clearly notified of the transition to the probability B state.

(Time t5)
With regard to the loss variation of the 30th variation (the remaining variation number of the state of probability variation A is one), when the symbol variation time “1 second” has elapsed, at time t5, the special symbol variation in-process (FIG. 12) in step S351. The determination is YES, and a “variation stop command” is transmitted to the effect control unit 24 (step S352). When receiving the change stop command, the effect control unit 24 sets the change stop effect (step S761) and causes the corresponding change stop effect to appear. Next, when the remaining probability variation A count becomes “remaining once” (step S762: YES), the process proceeds to step S763, and the probability variation B state effect is set (step S763). Thereby, as shown in FIG. 30, the effect mode by the screen of the liquid crystal display device 36 switches from the probability variation A state effect to the probability variation B state effect.

  Further, the loss variation time of the 30th variation (the remaining variation number of the probability variation A state is one time) is finished, and the variation stop timer time “0.5 seconds” is obtained in step S361 of the special symbol variation suspension process (FIG. 13). (Step S371: YES), the process proceeds to step S362, and the special symbol operation status is switched to “special symbol standby (01H)” (step S362). Next, the process proceeds from step S363 to step S366, and it is determined whether or not the value of the probability variation counter has reached zero (the 99th time). Here, since the value of the probability variation counter is not yet zero (the 99th time), the determination in step S366 is NO, and 1 is subtracted from the value of the probability variation counter (step S367). Next, it is determined whether or not the value of the probability variation counter after subtraction is zero (step S368). Since the value of the probability variation counter after subtraction is “69” and is not yet zero, the process proceeds from step S368 to step S371, and it is determined whether or not the value of the probability variation A number counter is zero (step S371). Since the value of the probability variation A number counter is “1” and is not yet zero (step S371: NO), the process proceeds to step S372, and 1 is subtracted from the value of the probability variation A number counter (step S372). Since the value of the probability variation A number counter after subtraction is zero (step S373: YES), the state designation by the variation pattern distribution code is switched to the probability variation B state (02) (step S374), and the special symbol variation suspension processing is performed. Exit. As a result, the probability variation state (privilege game state) of the main control unit 20 enters the probability variation B state (the number of variations 31 to 99) from the probability variation A state.

(Time t6)
Thereafter, a hold subtraction command is transmitted at time t6 (FIG. 10, steps S322 to S323), and the effect control unit 24 receives this hold subtraction command and updates the hold number display (FIG. 24, steps S711 to S323). S713).

  Next, the remaining “remaining probability variation number command” of 69 times is transmitted (FIG. 10, step S325). Further, the remaining “remaining probability change A number command” is transmitted (FIG. 10, step S327). The effect control unit 24 receives the remaining probability variation number command and the remaining probability variation number command (step S721 in FIG. 25, step S731 in FIG. 26). Thereby, the production control unit 24 can grasp the remaining number of times of probability variation until the probability variation state ends, and can notify the player as necessary (steps S732 to S733 in FIG. 26).

  Next, in step S341 of the special symbol variation pattern setting process (FIG. 11), referring to the variation pattern selection table of FIG. 7, one variation pattern is determined according to the variation pattern distribution code, the big hit determination flag, and the number of reserved balls. To do. Here, since the probability variation B state (variation pattern distribution code 02) and loss are assumed, the variation pattern of “normal variation of 2 seconds” is selected at a ratio of 234/239 according to the variation pattern selection table. The variation pattern designation command of “2 seconds normal variation” is transmitted to the effect control unit 24 (step S342), and “2 seconds” is set in the special symbol variation timer as the symbol variation time (step S343).

  When the effect control unit 24 receives the “2-second normal change” change pattern designation command, the effect control unit 24 sets a change pattern of the decorative pattern corresponding to this command (step S741). On the screen of the liquid crystal display device 36, the decorative design changes the design for a design change time of “2 seconds”. The time length of the symbol variation time “2 seconds” is shorter than the symbol variation time (5 seconds to 12 seconds) of the normal variation performed under the normal state (variation pattern distribution code 00), and the probability variation. It is longer than the fluctuation time of the symbol fluctuation (30 seconds in the case of no reach) for 30 times under the A state. Therefore, the probability variation B state is executed with a variation time of “2 seconds” that is twice the length of 30 symbol variations under the probability variation A state. Of course, when a loss or a big hit occurs after reaching, a longer variation time is set according to the variation pattern selection table of FIG.

  Next, a special symbol designation command is transmitted to the effect control unit 24 for the special symbol stop symbol determined in step S329 of the special symbol variation start process (FIG. 10) (step S331). When receiving the symbol designation command, the effect control unit 24 proceeds from step S751 to step S754 in the process of FIG. 28, determines the stop symbol (decoration symbol) and the notice effect of the change by lottery (step S754), This is displayed on the liquid crystal display device 36. This continues until the 99th fluctuation.

(Time t7)
When the symbol variation time “2 seconds” has elapsed, the determination in step S351 of the special symbol variation processing (FIG. 12) is YES, and a “variation stop command” is transmitted to the effect control unit 24 (step S352). When this change stop command is received, the effect control unit 24 sets the stop effect (step S761) and causes the corresponding stop effect to appear.

  Next, in step S353 of the special symbol changing process (FIG. 12), the special symbol operation status is switched to “special symbol stopped (03H)”, and the variable stop timer is set to “0.5 seconds” (step S353). When the special symbol stop timer time “0.5 seconds” elapses, the special symbol operation status is switched to “special symbol standby (01H)” in the special symbol fluctuation suspension processing (FIG. 13) (step S362). ).

  Next, it is determined whether or not the stop symbol is a big hit symbol (step S363). Here, since the case where the lost symbol stops is handled, the program proceeds from step S363 to step S366, and determines whether or not the probability variation counter is zero. Here, since the value of the probability variation counter is 69, the determination in step S366 is NO, and the value of the probability variation counter is decremented by 1 (step S367). Then, it is determined whether or not the value of the probability variation counter after subtraction is zero (step S368).

  Since the value of the probability variation counter after subtraction is “68” and is not yet zero, the process proceeds from step S368 to step S371, and it is determined whether or not the value of the probability variation A number counter is zero (step S371). Since the value of the probability variation A number counter is “0” (step S371: NO), the special pattern is maintained while maintaining the designated state (probability variation B state) of the variation pattern distribution code 02 without performing the processing of steps S372 to S374. Exit processing during variable stop.

(Time t7 to t8)
From time t7 to time t8 in the middle of the probability variation B state, the same processing as in the case of the first symbol variation described above is repeated until the variation count 29th. The time t8 in the middle shows the start time of the symbol fluctuation when the remaining probability variation is 10 times.

  In the process of FIG. 26, the effect control unit 24 sets the remaining probability variation number every time it receives the remaining probability variation command transmitted in step S325 of the special symbol variation start process (FIG. 10) (step S731), and the remaining It is checked whether or not the displayed numerical value is “9” or less, that is, whether or not the probability variation remaining count is 10 or less (step S732). When the remaining display value is “9” (10 times of remaining probability change) (step S732: YES), “9 remaining times” is displayed on the screen of the liquid crystal display device 36.

  In this way, with respect to each symbol variation of the remaining display number “9” to “0” (probable change remaining number of times 10 to zero), the remaining display number “9” to “last” are displayed in order. The number of times is counted down and notified to the player (step S733).

(Time t9 to t10)
At time t9, the symbol variation reaches the 99th variation count (the remaining variation count in the probability variation B state is 1).

  With respect to the loss variation of the 99th variation, when the symbol variation time “2 seconds” has elapsed, the determination in step S351 of the special symbol variation processing (FIG. 12) becomes YES at time t10, and the “variation stop command” is produced. It is transmitted to the control unit 24 (step S352). When receiving the change stop command, the effect control unit 24 sets the change stop effect (step S761) and causes the corresponding change stop effect to appear. Next, the process directly proceeds from step S762 to step S764, and it is determined whether or not the remaining probability variation B count is 1 (step S764). Since the remaining probability variation B is 1 (step S764: YES), the process proceeds to step S765, and the normal state effect is set (step S765). Thereby, as shown in FIG. 30, the effect mode by the screen of the liquid crystal display device 36 is switched from the probability variation B state effect to the normal state effect.

  In addition, when the loss variation at the 99th variation (the remaining variation number of the probability variation B state is one stop) and the variation stop time “0.5 seconds” elapses, in the special symbol variation suspension processing (FIG. 13), The special symbol operation status is switched to “special symbol standby (01H)” (step S362).

  The program in FIG. 13 proceeds from step S363 to step S366. Here, since the value of the probability variation counter is not yet zero (the 99th time), the determination in step S366 is NO, and 1 is subtracted from the value of the probability variation counter (step S367). Since the value of the probability variation counter after subtraction is “0”, the process proceeds from step S368 to step S369, and the special figure probability variation state flag is turned OFF. Further, the state designation of the variation pattern distribution code is returned to the normal state (00) (step S370). As a result, as shown in FIG. 30, the probability variation state (privilege gaming state) ends, and a normal low probability state is entered.

<Modification>
In the above embodiment, the game board in which the game ball flows down on the left side of the game area 3a has been described as an example. It can also be configured to enjoy.

  FIG. 31 shows an example of the configuration of a game board that can enjoy a probability variation state (privilege game state) by so-called right-handed game. In this example, a so-called gate (normal symbol start port 37) and special symbol start port 35 are moved to the right side, and a second special variable winning device 42 is newly added to the right side. When the game ball flying to the right side of the game area 3a of the game board 3 passes through the normal symbol starting port 37 on the right side, the movable wing piece 47 of the tulip-shaped special symbol starting port 35 positioned below the lottery is drawn. Open with a very high winning probability. Then, a game ball wins in the opened special symbol start opening 35 and wins a big win in the special symbol variation display game, thereby opening the open door 42b of the second special variation winning device 42 on the right side. The configuration is such that a game ball wins the winning opening 40.

  Further, the second normal symbol starting port 37, the second special symbol starting port 35, and the second special variable winning device in the state where the normal symbol starting port 37 and the lower starting port 35 are left as they are in the configuration of the game board of FIG. 42 can be added to the right side and the movable piece 47 of the second special symbol start port 35 can be opened by passing the game ball through the second normal symbol start port 37 on the right side.

  Further, the second normal symbol start port 37 and the second special variable winning prize are left in the state where the normal symbol start port 37 and the tulip-shaped special symbol start port (lower start port) 35 are left as they are in the configuration of the game board of FIG. Only the device 42 may be added on the right side, and the tulip-shaped lower start opening 35 may be configured to use the one located in the center. That is, when entering the (privilege gaming state), the game ball passes through the right second normal symbol start opening 37, thereby opening the movable piece 47 of the lower start opening 35 and lowering the game ball flowing down on the right side. A winning path leading to the start opening 35 is newly formed by linkage of a nail, a movable piece 47, a projecting member, and the like so that the special symbol starting opening 35 can be easily won. Then, when a big win is won in the special symbol variation display game, the right special variation winning device 42 on the right side is opened, and the game ball is awarded to the large winning opening 40.

  In the above embodiment, 30 times out of the total 99 fluctuations in the probability variation state are the first half and the remaining 69 times are the second half. However, the ratio is not limited to such a ratio. It is possible to divide into the preceding and following sections with an arbitrary number of times of symbol variation as a boundary, with variation as a unit.

  In the above embodiment, the timing or condition for switching from the probability variation A state to the probability variation B state is determined based on the number of symbol fluctuations. However, the present invention is not limited to this, and the probability variation A state to the probability variation B state is determined. The time or condition for switching to may be determined by lottery.

  Further, in the above embodiment, the countdown display of the remaining fluctuation count at which the privilege gaming state ends is performed from the middle of the probability variation B state which is the latter half section of the privilege gaming state, but the probability variation A which is the first half section of the privilege gaming state. The countdown display may be started from the middle of the state, that is, from the predetermined number of fluctuations before switching from the probability variation A state to the probability variation B state.

  The variation pattern selection table shown in FIG. 7 is an example, and can be changed as appropriate. For example, in the case of FIG. 7, when a loss occurs during the probability variation A state, only the reachless variation variation pattern (one second variation pattern) indicated as “normal variation of 1 second” dedicated to the probability variation A state is selected. In addition to this one-second fluctuation pattern, a reach-less loss fluctuation pattern (two-second fluctuation pattern) shown as “normal fluctuation of 2 seconds” dedicated to the probability change B state is selected, or further reach loss shown as reach loss 1 to 10 A variation pattern or the like may be selected. However, for these two-second variation patterns and loss variation patterns such as reach loss 1 to 10, the ratio selected in the probability variation A state is set to be lower than the ratio selected in the probability variation B state. In this way, the variation pattern is defined so that, on average, the variation time of the symbol in the first half section of the privilege gaming state is relatively shorter than the variation time of the symbol in the second half section as a whole in the period of the privilege gaming state. be able to.

  In the case of FIG. 7, 11 to 15 per reach are selected when hitting during the probability variation A state, but 1 to 10 per reach is additionally selected when hitting during the probability variation A state. Good. However, when including 1 to 10 hit fluctuation patterns per reach, similarly, the ratio at which the hit fluctuation pattern is selected in the probability variation A state is set lower than the ratio selected in the probability variation B state. To do. In this way, the variation pattern is defined so that, on average, the variation time of the symbol in the first half section of the privilege gaming state is relatively shorter than the variation time of the symbol in the second half section as a whole in the period of the privilege gaming state. be able to.

  Also, from the standpoint of increasing the speed at which the ball hits when hitting the jackpot, the opening production time at the big hit is shorter when the big hit from the probability variation A state is shorter than when the big hit from the probability variation B state. May be set. The same applies to the ending performance time.

In this case, for example, the following forms (a) and (b) are adopted.

(A) lottery means (S328) for performing a lottery to determine whether or not to give a special gaming state advantageous to the player when the starting condition is satisfied;
Based on the lottery result by the lottery means, at least one of a plurality of types of fluctuation patterns (normal fluctuation, reach lose, fluctuation pattern group per reach) determined in advance with respect to the fluctuation time of the symbols to be variably displayed on the display means Variation pattern determining means (S341 to S343) for selectively determining
Symbol display control means (S209, S306 to S308) for causing the display means to display a variable symbol and to stop and display the predetermined symbol based on the variation pattern determined by the variation pattern determination unit;
Special game state granting means (S210) for granting the special game state to the player on condition that the display is stopped and displayed in a special manner on the display means;
Based on the completion of the special gaming state, a transition is made to a privilege gaming state in which the transition to the special gaming state is easier than the normal gaming state until the number of times the symbol changes reaches a predetermined upper limit number. Gaming state transition means (S452, S459, S370, S374),
The variation pattern determination means is a symbol variation time in the first half of the period (probability variation A state) that is shifted to the privilege gaming state by the gaming state transition means (FIG. 7: “1 second The above-mentioned variation so that the “normal variation pattern only for probability variation A”) is relatively shorter than the symbol variation time (the variation pattern belonging to code 02) in the latter half of the bonus gaming state (probability variation B state). Assuming a ball game machine that prescribes the pattern,
The special game state giving means (S210) includes a variable winning device (special variable winning device 42) configured to be able to open a winning opening where a game ball is easy to win, and a variable winning device for controlling the operation of the variable winning device. Management means (S403 to S407),
When the lottery device management means wins the lottery by the lottery means, the special game state is executed as an opening effect to notify the start of the special game state (S411 to S414), and the variable prize device is a predetermined pattern. And control the execution of the round game released at (S421 to S424, S431 to S439) and the execution of the ending effect that tells the end of the special gaming state (S446 to S448),
Of these, at least for the opening effect time for executing the opening effect, the opening effect time to be executed when the lottery by the lottery means is won in the first half section (probability variation A state). ) Is set shorter than the opening effect time to be executed when the lottery by the lottery means is won (performed in step S413 in FIG. 15). Specifically, in step S413 of FIG. 15, the current variation pattern distribution code is referred to (variation pattern distribution code when winning big hit), and if the variation pattern distribution code 002 (probability variation B state), the ending effect time is set to 10 for example. If the variable pattern distribution code 001 (probability variation A state), the opening effect time is set to a value shortened to, for example, 5 seconds. In this way, the time for digesting the first half section (probability A state) is shortened by the amount that the opening effect time is shortened, and the speed at which the ball is increased when the big hits are extended can be increased.

  (B) In the ball game machine of (a), at least the ending effect time for executing the ending effect is executed when the lottery by the lottery means is won in the first half section (probability variation A state). The ending effect time is set to be shorter than the ending effect time executed when the lottery means is selected in the latter half section (probability variation B state) (performed in step S447 in FIG. 18). Specifically, in step S447 of FIG. 18, the current variation pattern distribution code (variation pattern distribution code at the time of winning the big hit) is referred to. If the variation pattern distribution code 002 (probability variation B state), the ending effect time is set to 5 for example. If the variable pattern distribution code 001 (probability variation A state), the ending effect time is set to a value shortened to 3 seconds, for example. In this way, the time for digesting the first half section (probability variation A state) is shortened by the amount that the ending effect time is shortened, and it is possible to increase the speed at which the ball is increased when hitting the big hit.

  Also, in the above embodiment, the period is divided into the first half and the second half for the "probability change state (probability change)" in which the special symbol probability change function, the special symbol time reduction function, the normal symbol probability change function, the normal symbol time reduction function, and the open extension function are activated. However, it is applied to the “short time state (short time)” in which the special symbol time shortening function, the normal symbol probability changing function, the normal symbol time shortening function, and the open extension function are activated, and the period is divided into the first half and the second half. The design variation time in the first half section may be set to be relatively shorter than the design variation time in the second half section or vice versa.

  The present invention can be applied to a count-down type ball game machine in which a privilege gaming state such as a high probability state ends on condition that the number of symbol fluctuations reaches a predetermined upper limit value.
