Description

  The present invention relates to a ball game machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball game machine, and more particularly to a ball game machine that realizes an appropriate performance operation according to an operation state.

  A ball game machine such as a pachinko machine has a symbol start opening provided on the game board, a symbol display section for stopping a plurality of symbols after changing for a predetermined time, and a grand prize opening for opening and closing the opening and closing plate. Configured. When the detection switch provided at the symbol start port detects the passing of the game ball, the symbol display unit changes the display symbol for a predetermined time (this operation is called symbol variation operation), and then the special symbol is aligned and stopped. Then, it becomes a big hit state, and the big winning opening is repeatedly opened to generate a profit state advantageous to the player.

  Whether or not to generate this profit state is determined by a jackpot lottery executed on the condition that a game ball wins at the symbol start opening, and the above symbol variation action is based on this lottery result. It has become. For example, when the lottery result is in a winning state, an effect operation called reach action (reach effect) is executed for about 20 seconds, and then the special symbols are aligned.

  On the other hand, a similar reach action may be executed even in the case of a lost state. In this case, the player pays close attention to the big hit state and pays close attention to the transition of the performance operation.

  By the way, when a game ball wins further at the symbol start opening during the symbol variation operation as described above, the subsequent big hit lottery operation is put on hold, and the symbol variation operation being executed ends in a losing state. The jackpot lottery will be held after the profit status due to the jackpot is over. However, the number of holds in the lottery operation (variable hold number) is limited to four, and the winning at the symbol starting point after that only contributes to the winning ball, and does not contribute to the big hit lottery. For this reason, depending on the player, when the number of variable suspension reaches four, the subsequent launch of the game ball may be stopped, which leads to a decrease in the sales of the game hall.

  On the other hand, in a game machine in a start slump state in which the symbol variation operation is rarely performed because the winning frequency at the symbol start opening is low, the player feels great stress and continues to play the game on the gaming machine. Losing motivation will eventually reduce the availability of the gaming machine, which in turn will reduce the sales of the gaming hall.

  Here, even if the gaming machine is in the start slump state, if a gaming machine capable of continuing the game without feeling stress can be realized, it will greatly contribute to the management of the gaming hall. On the other hand, even when the winnings at the symbol start opening are continuous, if a gaming machine that does not need to break the gaming rhythm can be realized, a great joy can be given to the player.

  This invention is made based on said idea, and makes it a subject to provide the bullet ball game machine which can implement | achieve presentation operation of the appropriate length according to the operation state of a game machine.

In order to solve the above-mentioned problems, the invention according to claim 1 determines whether or not a profit state advantageous to the player is generated by a big hit lottery process when a winning state in which a game ball passes through the symbol start opening occurs. In addition, this ballistic gaming machine notifies the player of the success / failure result through the production operation determined by the production lottery process, and the production lottery process varies depending on the operation results of the game machine. The performance of the production operation is performed in accordance with the value of the production mode, which is executed with reference to the mode value and the number of fluctuation suspensions that means the number of suspension of transition to the production operation, and is increased or decreased in the forward direction or the opposite direction. The performance operation that is configured so that the time can be changed and is executed when the big hit lottery process is out includes the first loss effect that notifies the result of the losing state after the production operation including the reach production, and the reach production. After no directing action The second losing effect is roughly divided into a plurality of sets having different production times, and the number of variable suspensions exceeds a determination value in a predetermined game section. When the excess time is greater than a predetermined reference value, the value of the effect mode is configured to be changed in the forward direction, and when the value of the effect mode is changed in the forward direction, While the selection probability of which of the second losing effects is to be executed is maintained, the second losing effect is executed by changing the selection distribution ratio of the plurality of losing effects included in the second losing effect. The expected value of the production time in this case is configured to be equal to or less than the expected value in the value of the production mode so far.

The invention according to claim 2 determines whether or not to generate a profit state advantageous to the player by a big hit lottery process when a winning state in which the game ball passes through the symbol start opening occurs, A ball and ball game machine that informs a player through the production operation determined by the production lottery process, and the production lottery process is performed with the value of the production mode that changes in accordance with the performance of the game machine and the production operation. In response to the value of the production mode that is executed with reference to the variable suspension number that means the number of transition suspensions, and is increased or decreased in the forward direction or the opposite direction, the production time of the production operation can be changed, The production operation that is executed when the big hit lottery process is out of the first lost production that notifies the success / failure result of the disengagement state after the production operation including the reach production, and the production operation that does not include the reach production. Notify the result The second losing effect is roughly divided into the second losing effects, the effect time is set to be shorter than the first losing effect on average, and the excess time during which the number of variable suspensions exceeds the determination value in a predetermined game section, is greater than the predetermined reference value, the value of the effect mode with configured to be changed in the forward direction, the value of the effect mode is changed to the forward direction, the first loss effect and the second loss effect The second allocation effect is selected with a selection probability higher than that by changing the selection distribution ratio of which to execute.

  As described above, according to the present invention, it is possible to realize a bullet ball game machine that realizes an appropriate performance operation according to an operation state.

The operation parameter for changing production mode is illustrated.

  Hereinafter, embodiments of the present invention will be described in detail based on a pachinko machine (first-type ball game machine) according to an example. FIG. 1 is a front view showing a pachinko machine 1 according to the present embodiment. The illustrated pachinko machine 1 includes a rectangular frame-shaped wooden outer frame 2 that is detachably mounted on an island structure, and a front frame 4 that is pivotably mounted via a hinge 3 fixed to the outer frame 2. It consists of A game board 5 is detachably attached to the front frame 4 from the back side, and a glass door 6 and a front plate 7 are pivotally attached to the front side so as to be freely opened and closed.

  An upper plate 8 for storing game balls for launch is mounted on the front plate 7, and a lower plate 9 for storing game balls overflowing from or extracted from the upper plate 8 and a launch handle 10 are mounted at the bottom of the front frame 4. And are provided. The launch handle 10 is linked to the launch motor M1, and a game ball is launched by a striking rod that operates according to the rotation angle of the launch handle 10.

  An elliptical push button 11 with a built-in lamp is provided at the approximate center of the upper plate 8. The push button 11 is provided at a position where it can be operated with the left hand of the player, and the player can operate the push button 11 without releasing the right hand from the firing handle 10. This push button 11 does not function normally, but when the game state becomes, for example, a “button chance state”, the built-in lamp is turned on and can be operated.

  On the right side of the upper plate 8, an operation panel 12 for ball lending operation for the card-type ball lending machine is provided, a remaining amount display unit 12a for displaying the remaining amount of the card with a three-digit number, and a predetermined amount of game balls A ball lending switch 12b for instructing ball lending and a return switch 12c for instructing the return of the card at the end of the game are provided.

  As shown in FIG. 2, the game board 5 is provided with a guide rail 13 formed of a metal outer rail and an inner rail in an annular shape, and a liquid crystal color display 14 is provided at the approximate center of the game area 5a inside. Has been placed.

  A forward pass switch SW-F that detects a game ball that is launched toward the guide rail 13 is provided at the launch position of the game ball that can be played by the launch handle 10. On the other hand, a reverse passage switch SW-R that detects a game ball that moves backward on the guide rail 13 and returns to the upper plate 8 is provided at a location close to the proximal end of the guide rail.

  In this embodiment, the guide rail is provided at its end with a swing piece H that rotates only in the forward direction and prevents entry of a game ball that bounces off from the game area 5a. Entered game balls will not return to the guide rail. However, when the operation of the firing handle 10 is inappropriate, there is a game ball that cannot pass through the position of the swing piece H due to insufficient launch speed of the game ball. It is detected by the pass switch SW-R.

Therefore, a value (= NUM _F −NUM _R ) obtained by subtracting the number NUM _{R of} game balls that have passed through the backward pass switch SW-R from the number NUM _{F of} game balls that have passed through the forward pass switch SW-F, This is the number of game balls actually related to the ball game operation. Of course, the attachment positions of the forward pass switch SW-F and the reverse pass switch SW-R are not limited to the illustrated positions, and can be changed as appropriate.

  By the way, two symbol starting ports 15, a big winning port 16, four normal winning ports 17, and gates 18 as right and left passing ports are arranged at appropriate positions in the game area 5a. Each of these winning openings 15 to 18 has a detection switch inside, and can detect the passage of a game ball.

  The liquid crystal display 14 is a device that variably displays a special symbol related to the big hit state and displays a background image and various characters in an animated manner. The liquid crystal display 14 has a special symbol display part DISP in the center and a normal symbol display part 19 in the upper right part. The normal symbol display unit 19 displays a normal symbol. When a game ball that has passed through the gate 18 is detected, the displayed normal symbol fluctuates for a predetermined time, and lottery is performed when the game ball passes through the gate 18. The stop symbol determined by the random number for lottery is displayed and stopped.

  In this embodiment, the symbol start opening 15 is enlarged or reduced by an electric tulip having a pair of opening and closing claws, and when the stop symbol after the fluctuation of the normal symbol display unit 19 hits and the symbol is displayed, the opening and closing claws are displayed. It is expanded for a predetermined time. When a game ball wins the symbol start port 15, the display symbol of the special symbol display unit DISP fluctuates for a predetermined time, and the stop is determined based on the lottery result corresponding to the game ball winning timing at the symbol start port 15. Stop at the symbol.

  The special winning opening 16 is opened and closed by an opening / closing plate 16a that can be opened forward. When the special symbol display section DISP has a special symbol such as “7. The special game referred to is started, and the opening / closing plate 16a is opened. Further, there is a specific area 16b inside the special winning opening 16, and when a winning ball passes through the specific area 16b, a special game advantageous to the player is continued.

  After the opening / closing plate 16a of the big prize opening 16 is opened, the opening / closing plate 16a is closed when a predetermined time elapses or when a predetermined number (for example, 10) of game balls wins. At this time, if the game ball does not pass through the specific area 16b, the special game ends. However, if the game ball passes through the specific area 16b, the special game is continued up to, for example, 16 times, which is advantageous to the player. To be controlled. In addition, when the stop symbol after the change of the special symbol display part DISP is a specific symbol of the special symbols, a privilege that the game after the end of the special game is in a high probability state is given.

  FIG. 3 is a block diagram illustrating the overall configuration of the pachinko machine 1 according to the embodiment. As shown in the figure, the pachinko machine 1 realizes an audio game effect and lamps while a main control board 30 that mainly controls the game operation, a symbol control board 31 that controls the operation of the liquid crystal display 14, and the like. The sound / lamp control board 32 to be blinked, the payout control board 33 for paying out the game ball by controlling the payout motor M2, the launch control board 34 for launching the game ball by the launch motor M1, and each part of the apparatus receiving AC24V And a power supply substrate 35 for supplying a DC voltage to the main body.

  As shown in the drawing, a push button 11 incorporating a lighting lamp is connected to the sound / lamp control board 32. An ON signal indicating that the push button 11 has been operated is transmitted from the sound / lamp control board 32 to the symbol control board 31.

  The main control board 30, the symbol control board 31, the voice / lamp control board 32, and the payout control board 33 are each mounted by a computer circuit having a one-chip microcomputer, and the symbol control board 31, the voice / lamp control board 32 are mounted. The payout control board 33 directly receives a control command from the main control board 1 and realizes individual control operations.

  Hereinafter, the functions mounted on the main control board 30, the design control board 31, and the sound / lamp control board 32 and the operations realized by the circuits are collectively referred to as the main control section 30 and the design control section 31. , And the voice / lamp control unit 32.

  FIG. 4 is a block diagram illustrating a circuit configuration of the main control unit 30. As shown in the figure, the main control unit 30 includes a CPU circuit 30a composed of a one-chip microcomputer, a system clock generation unit 30b that generates a clock signal Φ0 that is an integer multiple of the CPU operation clock CLK, and an address signal from the CPU. Based on the decoding circuit 30c for generating the chip select signal of each part, the output port circuit 30d for outputting data from the CPU, the input port circuit 30e for the CPU to take in external data, and the sub-control parts 31, 32 , 33, and an output drive circuit 30f for outputting a control command and a switch input circuit 30g for inputting ON / OFF states of switches of each part of the game board. The CPU circuit 30a incorporates a CPU core equivalent to Z80CPU (Zilog).

  The main control unit 30 configured as shown in FIG. 3 performs overall control of the operation of the pachinko machine 1 by executing the timer interrupt process shown in FIG. 5 every predetermined time (2 mS). In the following, referring to FIG. 5, when a timer interrupt occurs, the contents of each register are saved in the stack area (ST10), and then random number generation processing is first performed (ST11). The random number generation process includes a process for updating the winning counter RG and the big hit counter CT used in the lottery operation in the normal symbol process ST21 and the special symbol process ST26.

  In step ST11, the winning counter RG and the big hit counter CT are updated by increment (+1) processing within a predetermined numerical value range, respectively, and the updated counter values are the hit determination random number value and the big hit determination random number, respectively. It is used as a numerical value in the lottery operation.

  Specifically, the value of the winning counter RG is used in the lottery operation in the normal symbol processing (ST21) when the game ball passes through the gate 18, and the value of the big hit counter CT is determined by the game ball starting the symbol. When it passes through the mouth 15, it is used for the lottery operation in the special symbol process (ST26). The random number generation process includes a winning symbol random number generation process and a big bonus symbol random number generating process for determining a stop symbol in the normal symbol display unit 19 and the special symbol display unit DISP.

  When the random number generation process (ST11) as described above is completed, a timer subtraction process is performed for the timer that manages the time of each gaming operation (ST12). Next, when the value of the determination flag FLG is 1, the variable TIME is incremented (ST13, 14). The determination flag FLG is a flag indicating whether or not the number of change suspensions HORYU is currently two, and is set in the processing of steps ST35 and ST36 in FIG.

  In this embodiment, when the variable hold number HORYU = 2, the determination flag FLG = 1 and the variable TIME is incremented. However, since the interrupt process shown in FIG. 5 is performed every 2 mS, TIME × 2 The value means the total occupied time (mS) in which the variable holding number HORYU is 2.

After the above processing, signals from various switches including the detection switch of the symbol start port 15 and the gate 18 and the passing switches SW-F and SW-R of the game ball are inputted and stored (ST15). Each timer is subtracted in the processing of Step ST 1 2 is for managing the opening time of the electric tulips and winning opening 16 and other game effects time. Further, in the switch input management process (ST 15 ), the value of the big hit counter CT is acquired on the condition that the detection switch of the symbol start port 15 is in the ON state and the number of fluctuation hold has not reached the upper limit value. The

  Subsequently, based on the variable TIME obtained in the update process of step ST14, if necessary, the effect mode changing process is performed (ST16). FIG. 6 illustrates in detail the processing content of step ST16, and FIG. 7 illustrates the effect mode changing process in more detail.

  As shown in FIG. 6, first, the game ball is won in the symbol start opening 15 (start opening winning), and the variable hold number HORYU is less than 4 (ST31, 32). The hold number HORYU is incremented (ST33).

  In the present embodiment, even if the start symbol winning state during the symbol variation effect in the special symbol display unit DISP, the jackpot lottery processing in the special symbol processing (ST26) is put on hold, but the variable hold number HORYU The number of winnings in the hold state is shown. Further, when the number of winnings in the hold state reaches four, the subsequent starting opening winnings do not contribute to the big hit determination process until the number of winnings becomes less than four. Therefore, the variable holding number HORYU = 4 In this case, the process of step ST33 is skipped.

  Subsequently, it is determined whether or not the current variable hold number HORYU is 2 or more. If HORYU ≧ 2, the determination flag FLG is set to 1, and if HORYU <2, the determination flag FLG is set to 0 (ST34). -ST36). In this embodiment, this is based on a state in which the number of variable holds is 2 as a criterion, and the duration of the state equal to or greater than the criterion value is accumulated with a variable TIME to determine the operating trend of the gaming machine (specifically, start This is because the frequency of occurrence of the winning prize state is determined. Therefore, the condition for setting the determination flag FLG to 1 does not necessarily have to be HORU ≧ 2, but may be, for example, HORU ≧ 3.

  In any case, if the determination flag FLG is set, the value of the upper limit flag LM is determined (ST37). In this embodiment, since the upper limit flag LM is set when the total time TOTAL of the effect operation reaches 10 minutes (see ST57 in FIG. 8), the total time of the effect time is determined by determining the value of the upper limit flag LM. It will be determined whether TOTAL has reached 10 minutes.

  When the upper limit flag LM = 1, the value of the occupation time variable TIME (see ST14 in FIG. 5) for calculating the duration of the state in which the number of pending changes is 2 or more is stored in the buffer (ST38). ). This buffer is an update type rotary memory (ring buffer) having a storage capacity of 10 bytes, and the total occupied time TIME is stored at the memory position indicated by the pointer P. Thereafter, the variable TIME for managing the total occupation time and the upper limit flag LM are each cleared to zero (ST39).

  The pointer P is updated cyclically within the buffer range (ST40). Next, the most recent 10 bytes of data in the buffer area are added to calculate the average occupation time AVE (actually the value of average occupation time × 10) (ST41). Since the buffer is used cyclically, the data of the latest 10 bytes is simply added by simply adding the contents from the beginning to the end of the buffer area (10-byte area).

  By the processing of this step ST41, the frequency of the variation holding number ≧ 2 in the last 10 minutes of the total effect time of the variation operation, that is, whether the game ball is well won in the symbol start opening 15 or not so much? The trend becomes clear. Therefore, in this embodiment, the production mode is changed according to the magnitude of the start opening prize (ST42).

  The specific processing content is as shown in FIGS. 7A and 7B. When the average winning number AVE is located between the upper reference value and the lower reference value, the effect mode is not changed, but the upper reference When the value is exceeded, the effect mode is increased until the upper limit value is reached, thereby shortening the effect time. When the value is below the lower reference value, the effect mode is decreased until the lower limit value is reached, thereby increasing the effect time. In this embodiment, the production mode 1 to the production mode 5 are prepared, and the production time of the symbol fluctuation is shortened as the production mode increases.

  When the effect mode change processing is completed as described above, as shown in FIG. 5, after the control command generated at this stage is transmitted to the corresponding sub-control units 31, 32, 33 (ST17), an error occurs. Management processing is performed (ST17). The error management process is a determination as to whether or not an abnormality has occurred inside the device, such as whether or not the supply of game balls has stopped or the game balls are clogged. Next, after creating a control command for the payout control unit 34 (ST18), the control command generated in each of the above processes is transmitted to the corresponding sub-control unit (ST19).

  Next, normal symbol processing is performed on the condition that the current operation mode is not the hit mode (ST21). The normal symbol processing means determination as to whether or not to operate an ordinary electric accessory such as an electric tulip. Specifically, when it is determined that the game ball is passing through the gate based on the switch input result in step ST15, the winning counter RG updated in the random number generation process (ST11) is compared with the winning winning value. The If the comparison result is a winning state, the operation mode is changed to the winning operation mode. Also, if it is hit, processing for the operation of the ordinary electric accessory such as an electric tulip is performed (ST23).

  Subsequently, a necessary control command is transmitted to the corresponding sub-control unit (ST24), and special symbol processing is performed on the condition that the current operation mode is not a big hit (ST26). The special symbol process (ST26) is a determination as to whether or not to operate the first-type special electric accessory such as the special prize opening 16, and the specific processing content is as shown in FIG.

  In the present embodiment, when it is determined by the switch input process (ST15 in FIG. 5) that the game ball has passed through the symbol start port 15, the number of fluctuation hold becomes a value other than zero (ST31 in FIG. 6). -ST33). Therefore, in the special symbol processing, if the current fluctuation operation is not being performed (ST50) and the fluctuation holding number HORYU is not zero (HORY> 0), the big hit determination processing is executed after the calculation of HORYU ← HORYU-1. (ST51 to ST53).

  In the jackpot determination process (ST53), the value of the jackpot counter CT acquired in the switch input process (ST15) is compared with the jackpot winning value Hit. And if a comparison result is a winning state, it will change to the operation mode in jackpot. Then, after such a big hit determination process is finished, an effect lottery process for determining the content of the effect is executed (ST54).

  Although the specific content of the effect lottery process (ST54) is not particularly limited, in this embodiment, based on the effect lottery table TBL as shown in FIG. The production number) is determined. In FIG. 9, “a, b, c, d, e, f” in the “assignment rate” column is a portion that differs for each production mode, and is specifically described in FIG. ing. Further, the variation pattern number specifies the production time (variation time in the case of symbol variation), the final success / failure conclusion, the presence / absence of reach production, and the like.

  In the illustrated example, the fluctuation pattern numbers 1 to 3 mean a production operation of about 18 to 26 seconds in which the special symbols are aligned and the winning state is determined after the reach production, and the fluctuation pattern numbers 4 to 6 are the reach production. Means that the losing state is determined after about 16 to 24 seconds, and the variation pattern numbers 7 to 9 mean that the losing state is not accompanied with the reaching state and that the losing state is determined for about 4 to 12 seconds. Yes.

  In this embodiment, the variable hold number HORYU and an appropriate random number value RND are adopted as parameters for determining the change pattern number. For example, when the change hold number is 0 to 1, 1 is used. A probability of hitting / 300 is a big hit state, a probability of 299/300 × 10/100 is a loss state with a reach effect, and a probability of 299/300 × 90/100 is a loss state without a reach effect. (See FIG. 9).

  In this embodiment, the distribution rate in which the fluctuation patterns 1 to 3 are selected from the big hit state generated with a probability of 1/300 is 60:30:10 regardless of the magnitude of the fluctuation holding number HORYU. Yes. In addition, among the losing effects with reach effects that occur at a probability of 299/300 × 10/100, the distribution ratio at which the variation patterns 4 to 6 are selected is 10:30 when the variation holding number HORYU is 0 to 2. : 60. In addition, when the variable hold number HORYU is 3 to 4, the selection rate of the loss with reach effect is designed to be 299/300 × 6/100, unlike the case where the variable hold number HORYU is 0 to 2. However, the distribution ratio at which the variation patterns 4 to 6 are selected is the ratio of 10:30:60, as in the case where the variation hold number HORYU is 0 to 2.

  As described above, in the present embodiment, in the case of an effect that ends in a winning state (variation patterns 1 to 3) or a loss effect with a reach effect (variation patterns 4 to 6), the same regardless of the effect mode. For the lost production (variation patterns 7 to 9) without the reach production, the production operation is different for each production mode (see FIG. 10).

  Specifically, referring to FIG. 10, when the number of change hold is 2, when the effect mode is 1, the change pattern 7 having the effect time of 12 seconds is selected, but the effect mode is 2 In this case, not only the variation pattern 7 but also the variation pattern 8 having an effect time of 8 seconds is selected with a probability of 1/2. In the case of the production mode 3, the fluctuation pattern 8 is always selected, and in the case of the production mode 4, either the fluctuation pattern 8 or the fluctuation pattern 9 having the production time of 4 seconds is selected with a probability of 1/2. In the case of the production mode 5, the variation pattern 9 is always selected.

  The tendency is the same when the number of change hold is 3 to 4, and the change pattern 8 is always selected in the case of the production mode 1, but in the case of the production mode 2, it changes with a probability of 1/2. Either pattern 8 or variation pattern 9 is selected. In the production modes 3, 4, and 5, the variation pattern 9 having a production time of 4 seconds is always selected.

  In this way, as the production mode increases, the production time becomes shorter because the operating state of the gaming machine is earlier when the winning frequency to the symbol start port 15 is high. This is because it is preferable for the player to finish the production and start the next production operation that may be in the winning state.

  As described above, since the content of the current production operation is confirmed in the production lottery process (ST54), next, the current production time is added to the variable TOTAL managing the production total time (ST55). Then, it is determined whether or not the total production time TOTAL exceeds 10 minutes (ST56). If it exceeds, the upper limit flag LM is set to 1 and the variable TOTAL is cleared to zero (ST57). The upper limit flag LM is referred to in step ST37 as described above.

  Thereafter, after other necessary processing is completed, the processing returns to step ST27 in FIG. If it is a big hit, processing for the operation of the first type special electric accessory such as a big prize opening is performed (ST28). As described above, the effect contents of the symbol control unit 31 and the sound / lamp control unit 32 are defined by the change pattern number determined by the operation parameters such as the change hold number HORY, the effect mode, and the random number value RND.

  Therefore, when a variation pattern number is newly determined, a control command indicating the variation pattern number is transmitted to the symbol control unit 31 and the voice / lamp control unit 32 (ST29). In response to this control command, the symbol control unit 31 starts a symbol variation operation on the liquid crystal display 14, and the voice / lamp control unit 32 starts a voice effect and a lamp effect based on the received control command. It will be.

  Next, the register saved in the process of step ST10 is restored to finish the timer interrupt process (ST30). As a result, the process returns to the main routine. However, when the predetermined time (2 mS) has elapsed, the process of step ST10 is started again, so that the processes of steps ST10 to ST30 are repeated every 2 mS.

  As mentioned above, although the Example of this invention was described concretely, the concrete description content does not specifically limit this invention. For example, in the above embodiment, the production mode is switched to five stages of 1 to 5 and the production time of the loss production without the reach production is changed. However, it is not limited to such an embodiment. Absent.

  For example, as shown in FIG. 11, the selection probability of the production operation (variation patterns 4 to 6) accompanied by the reach production and the production operation (variation patterns 7 to 9) not accompanied by the reach production is represented by the production mode and the number of pending changes. It may be changed with. In addition, the portions described as A, B, C, D, E, and F in the “reach determination” column of FIG. 11 are portions that differ for each effect mode, and are specifically described in FIG. Has been.

  As shown in FIG. 12, when the variable holding number HORYU is 0 to 1, in the production mode 1, the presence / absence of the reach production is selected at a distribution ratio of 14:86, and in the production modes 2 and 3, the ratio is 10:90. The presence / absence of reach production is selected based on the distribution ratio.

  On the other hand, when the variable hold number HORYU is 2, in the production modes 1 and 2, the presence / absence of reach production is selected at a distribution ratio of 10:90, and in the production mode 3, reach production is performed at a distribution ratio of 6:94. Presence or absence is selected. Also, when the variable hold number HORYU is 3, the presence / absence of reach production is selected in the production mode 1 at a distribution ratio of 10:90, and in the production modes 2 and 3, reach production is performed at the distribution ratio of 6:94. Presence or absence is selected.

  In this way, the specific contents of the effect lottery are selected as appropriate, but also in the case of FIG. 12, the effect operation without the reach effect is easily selected as the effect mode is increased, and the effect time is shortened. It is designed as follows.

Furthermore, in the above-described embodiment, when the total production time TOTAL of the production operation reaches a predetermined value (for example, 10 minutes), the total occupied time TIME that has been the variable holding number HORY = 2 is stored in the buffer. the specific number (examples may be but one which is 10 times) repeated, had identified the operation tendency of the gaming machine, this specific method can also be appropriately changed.

  For example, instead of or in addition to specifying the total occupied time TIME in which the variable hold value was a specific value, the number of game balls to be fired may be specified. In this case, the smaller the number of fired shots, the easier the game machine tends to win the start opening. In addition, an appropriate inspection timing is provided such as when a game ball is launched, when winning a symbol start, or when a variable motion is started, and the variation holding number HORYU at the inspection timing is a predetermined value (for example, 3 or 1 or more) ) May be specified, or the total number of variable hold numbers HORYU at the inspection timing may be specified.

  In these embodiments, the total occupied time TIME is stored on the condition that the total production time TOTAL of the variable action reaches a predetermined value (10 minutes). A condition may be that the number of fires reaches a predetermined value, or that the number of winnings to the symbol start opening and the number of fluctuating actions reach a predetermined value.

  Alternatively, the total number of times that the variable holding number HORYU was in a predetermined value (eg, 3 or 2 or more) is accumulated, and on the condition that this reaches the predetermined value, an appropriate indication of the gaming state up to that time is appropriate. The parameter may be stored. Furthermore, an appropriate inspection timing is provided such as when a game ball is launched, when winning a symbol start, or when a variable motion is started, and the total number of times that the variation hold number HORYU at the inspection timing is in a predetermined value state, The appropriate number of parameters indicating the game state up to that time may be stored on the condition that the total number of the variable holding number HORYU at the inspection timing is a problem and the total number of times or the total number reaches a predetermined value. .

  FIG. 13 illustrates the above relationship, the vertical axis is an element for determining the storage timing for storing the operation parameter indicating the gaming state, and the horizontal axis is an example of a suitable operation parameter. It is.

  In each of the above embodiments, statistical data is calculated for each gaming machine, but instead of such a configuration, statistical data is calculated with a management computer or the like provided in each gaming hall, Based on the calculation result, the occurrence tendency of the start opening winning state may be determined for each gaming machine. In this case, the production mode is changed by entering a special prize opening or by artificially inputting a switch. However, this special prize opening is normally closed and receives an artificial operation. It is preferable to make it possible to enter the ball only in the case of a hit.

  In the embodiment shown in FIG. 6, a 10-byte area buffer is prepared, and every time the production total time TOTAL reaches a predetermined value, the occupation time TIME is stored cyclically and the latest 10 bytes of data are stored. However, it is not always necessary to take such a configuration. For example, simply, the ring buffer may be omitted, and the production mode may be changed by determining the occupied time TIME until that time every time the production total time TOTAL reaches a predetermined value. In the present invention, the occupation time TIME in such a case is of course included in the statistical data.

Further, in the above embodiment, the occupation time TIME in which the variable holding number HORYU was 2 or more is statistically calculated, and this is compared with a predetermined upper reference value and lower reference value to change the effect mode. However, this can be changed as appropriate. For example, the occupation time TIME _{3 in} which the variable hold number HORYU was 3 or more and the occupation time TIME _{1 in} which the variable hold number HORYU was less than ₁ are calculated statistically, and the occupation time TIME ₃ is a predetermined value. When the reference value TH _U is exceeded, the effect mode is changed so that the effect time is shortened. On the other hand, when the occupation time TIME ₁ exceeds the predetermined reference value TH _L , the effect mode is changed so that the effect time becomes longer. Is preferred.

  Furthermore, in the above embodiment, the total effect time TOTAL is calculated in the process of step ST55, but instead of this configuration, it is set to 1 at the start of the effect operation and reset to 0 at the end of the effect operation. An effect flag FG may be provided and the effect total time may be calculated by the same processing as in steps ST13 to ST14.
