Next, the pachinko machine 20 configured as described above
The operation of will be described. FIG. 7 shows the main controller 70.
5 is a flowchart showing an example of a main routine executed by This routine is executed every predetermined time (for example,
It is repeatedly executed every 2 msec.

When the main routine is executed, the CPU 72 of the main control device 70 causes the start winning process (step S100) illustrated in FIG. 8, the variation start process (step S102) illustrated in FIG. 9, and the example illustrated in FIG. The fluctuation stop process (step S104), the counter update process (step S106) illustrated in FIG. 11 are executed, and then the lost symbol counter update process (step S10) illustrated in FIG.
Repeat 8). For ease of explanation, first,
The counter update process and the lost symbol counter update process will be described, and then each of the other processes will be described.

In the counter updating process, as shown in FIG. 11, the CPU 72 of the main controller 70 increments the respective counters of the internal random number counter C1, the reach random number counter C2, the big hit symbol counter C3, and the fluctuation pattern counter C4. Is executed (step S24
0). The internal random number counter C1 is a loop counter used when determining whether or not it is a big hit, and is 0 in the embodiment.
Up to 629 are sequentially incremented by one. The reach random number counter C2 is a loop counter used when determining whether or not to perform a reach game, and in the embodiment, 0 to 11 are sequentially incremented by one. When the big hit symbol counter C3 determines the symbols (big hit symbols) at the time of fluctuation stop of the three symbols L, M, and R that are variably displayed on the special symbol display device 40 at the time of big hit. Is a loop counter used for
Up to 11 are sequentially incremented by the value 1. The fluctuation pattern counter C4 is on the left of the special symbol display device 40,
This is a loop counter used when deciding a pattern for variably displaying the three symbols L, M, R on the middle and right sides. In the embodiment, 0 to 99 are sequentially incremented by one. When each counter is updated in this way, each counter is
The data is stored in the counter buffer set in the predetermined area of the AM 76 (step S242), and the counter updating process is ended.

In the lost symbol counter updating process, FIG.
As shown in, the CPU 72 of the main control device 70 first executes a process of incrementing the lost symbol left counter Cl (step S250). The lost symbol left counter Cl is the left (center) of the symbols (loose symbols) at the time when the three symbols L, M, and R, which are variably displayed on the special symbol display device 40 at the time of loss, stop changing. It is a loop counter used when determining the symbol L, and in the embodiment, the value is incremented by 1 in order from 0 to the number obtained by subtracting the value 1 from the number of symbols. Subsequently, it is determined whether the lost symbol left counter Cl has a value of 0 (step S252), and when the lost symbol left counter Cl has a value of 0, the lost symbol right counter Cr is incremented (step S25).
4). Loss symbol right counter Cr, the left, middle and right 3 which are variably displayed on the special symbol display device 40 at the time of loss
Design of individual symbols L, M, R at the time of fluctuation stop (Loss design)
It is a loop counter used when determining the right symbol R among them, and in the embodiment, like the lost symbol left counter Cl, it increments by 1 in order from 0 to the number obtained by subtracting the value 1 from the number of symbols. Similarly, it is determined whether the lost symbol right counter Cr has a value of 0 (step S256), and when the lost symbol right counter Cr has a value of 0, the lost symbol counter Cm is incremented (step S).
258). Here, the loss symbol counter Cm is a symbol at the time of variation stop of the three symbols L, M, R which are variably displayed on the special symbol display device 40 at the time of loss (loss symbol). It is a loop counter used when determining the symbol M in the inside, and in the embodiment, like the lost symbol left counter Cl and the lost symbol right counter Cr, the numbers 0 to the number obtained by subtracting the value 1 from the number of symbols in order. Increment by one.

Incrementing each of the lost symbol counters Cl, Cr, Cm, or when it is determined in step S252 that the lost symbol left counter Cl is not 0, or in step S256 that the lost symbol right counter Cr is not 0. When it is performed, it is determined whether the lost symbol left counter Cl and the lost symbol right counter Cr match (step S260). When the lost symbol left counter Cl and the lost symbol right counter Cr do not match, each lost symbol counter Cl, Cm, Cr is stored in the lost symbol buffer set in a predetermined area of the RAM 76 (step S
262), and this routine ends. On the other hand, when the missing symbol left counter Cl and the missing symbol right counter Cr match, it is determined whether the missing symbol counter Cm also matches (step S264). Lost pattern left counter C
When l and the lost symbol right counter Cr match but the lost symbol counter Cm is different, each lost symbol counter Cl, Cm, Cr is stored in the lost reach symbol buffer set in a predetermined area of the RAM 76 (step S2).
66), and this routine ends. When all of the lost symbol counters Cl, Cm, Cr match, this routine is not a lost symbol, so this routine is performed without storing the lost symbol counters Cl, Cm, Cr in the lost symbol buffer or the lost reach symbol buffer. finish.

This lost symbol counter updating process is shown in FIG.
As can be seen from the flowchart of the main routine illustrated in FIG. 5, the process is repeatedly performed during the idle time until the main routine is executed every time a predetermined time elapses. Therefore, while other counters such as the internal random number counter C1 and the reach random number counter C2 count up each time the main routine is executed, the lost symbol left counter Cl is free every time the main routine is executed. It counts up each time it is repeatedly executed.

In the start winning process, as shown in FIG. 8, the CPU 72 of the main control device 70 first determines whether or not the game ball has won the starting opening 42 (step S20).
0). This determination can be performed depending on whether or not the special symbol starting port switch 44 is turned on. When it is determined that the game ball has won the starting opening 42, the number N of reserved balls is 4
It is checked whether it is less than (step S202). This is because, as described above, the maximum number of reserved balls is four in the embodiment.

When the number N of reserved balls is less than 4, the number N of reserved balls is incremented by 1 (step S2).
04), one of the special symbol variation holding lamps 41a to 41d is sequentially turned on from the left (step S206). Then, RA is executed in step S242 of the counter updating process of FIG. 11 and step S262 of the lost symbol counter updating process of FIG.
The internal random number counter value, the reach random number counter value, the big hit symbol counter value, and the lost symbol counter value stored in the buffer set in the predetermined area of M76 are also stored in the RAM76.
It is stored in the first area of the free storage areas of the reserved ball storage area set in the predetermined area (step S20).
8). FIG. 13 shows an example of the structure of the reserved ball storage area.
As shown in the figure, the reserved sphere storage area is an internal random number counter value, a reach random number counter value, a jackpot symbol counter value,
It is composed of one execution area and four holding areas capable of storing the lost symbol counter values one by one.

After the storage processing of each counter value in the reserved ball storage area is completed, when it is determined in step S200 that the game ball has not won the starting opening 42, or in step S202, the number N of reserved balls is determined. When it is not determined to be less than 4, it is determined whether or not the number N of reserved balls is greater than the value 0 (step S210), and the special symbol display device 4
At 0, it is determined whether or not the three symbols L, M, and R on the left, middle, and right are being variably displayed, or whether or not they are a big hit (step S212). When the number N of reserved balls is not 0, and the special symbol display device 40 is neither displaying variable nor a big hit, the value 1 is set to the fluctuation permission flag F1 (step S214), this routine is finished, and the holding ball is held. When the number N is 0, the special symbol display device 40 is being variably displayed, or is a big hit, this routine is ended without setting the variation permission flag F1.

In the fluctuation start process, as shown in FIG. 9, the CPU 72 of the main control device 70 first executes a process of judging whether or not the fluctuation permission flag F1 is 1 (step S220). When the fluctuation permission flag F1 is not the value 1, the number of reserved balls N is the value 0, or the three symbols L, M, and R on the left, middle, and right are being variably displayed by the special symbol display device 40, or a big hit. When it is determined that it is in the middle, the present routine is ended.

When the variation permission flag F1 has the value 1, the special symbol variation holding lamps 41a to 41d are sequentially set from the right side to 1
The light is turned off (step S222), the number N of reserved balls is decremented by 1 (step S224), and a process of shifting the data stored in the reserved ball storage area is performed (step S226). This data shift processing is processing for shifting the data stored in the four holding areas of the holding ball storage area illustrated in FIG. 13 by one block to the execution area side. That is, the data in the holding area A is used as the execution area and the data in the holding area B is used as the holding area A.
First, the data in the holding area C is moved to the holding area B and the data in the holding area D is moved to the holding area C.

Next, the special symbol display device 40 displays the three symbols L, M, and R on the left, middle, and right in a variable manner, and then sets a symbol when variable display is stopped. The display command determination process consisting of the left, middle, and right three pattern L, M, R variation pattern commands is performed (step S227), and the determined display command is displayed via the input / output processing circuit 80. It is sent to the control device 90 (step S228), and the value of 0
Is set (step S229), and this routine ends. The operation of the display control device 90 that receives the display command will be described later. The display command determination process in step S227 is performed using the flowchart illustrated in FIG.

In the display command determination processing, as shown in FIG. 14, the CPU 72 of the main control device 70 first determines whether or not the value of the internal random number counter C1 stored in the execution area of the reserved ball storage area is a big hit. Yes (Step S
300). This jackpot determination is performed by determining whether the value of the internal random number counter C1 is a jackpot value, for example, "7" or "322". In the embodiment, the internal random number counter C1 sequentially counts up from 0 to 629, so the probability of a big hit is 1/315.
Becomes If it is determined to be a big hit, the value of the big hit symbol counter C3 stored in the execution area of the holding ball storage area is set to the stop symbol command (step S310), and the big hit time variation pattern command determination process illustrated in FIG. 15 is performed. Then, the routine ends (step S312), and the present routine ends. In the jackpot variation pattern command determination process, RA
The value of the fluctuation pattern counter C4 stored in the buffer set in the predetermined area of M76 is checked (step S3
40), when the variation pattern counter C4 is less than 20, the pattern B is set to the variation pattern command (step S342), and the variation pattern counter C4 is 20 or more and 6 or more.
When it is less than 0, the pattern C is set to the variation pattern command (step S344), and the variation pattern counter C is set.
When 4 is 60 or more, the pattern D is set to the variable pattern command (step S346). Each pattern will be described later.

On the other hand, if it is determined in step S300 that it is not a big hit, it is determined whether or not the value of the reach random number counter C2 stored in the execution area of the reserved ball storage area is a reach (step S302). The reach hit determination is performed by determining whether or not the value of the reach random number counter C2 is the value per reach, for example, "7". In the embodiment, the reach random number counter C2 is 0 to
Since the numbers up to 11 are sequentially counted up, the probability per reach is 1/12. If it is judged to reach
Missing symbol counters Cl, Cm, stored in the missing reach symbol buffer set in a predetermined area of AM76,
The value of Cr is set in the stop symbol command (step S32
0), the variation pattern command for lost reach reach illustrated in FIG. 16 is performed (step S322), and this routine is ended. In the loose-reach variation pattern command determination processing, similarly to the jackpot variation pattern determination processing, the value of the variation pattern counter C4 stored in the buffer set in the predetermined area of the RAM 76 is checked (step S350), and the variation pattern counter is checked. When C4 is less than 50, the pattern B is set to the variation pattern command (step S352), and the variation pattern counter C4 is set to 5
When 0 or more and less than 90, the pattern C is set to the variation pattern command (step S354), and when the variation pattern counter C4 is 90 or more, the pattern D is set to the variation pattern command (step S356). In addition,
If it is determined in step S302 that the hit is not reach,
The values of the missing symbol counters Cl, Cm, and Cr stored in the execution area of the holding ball storage area are set in the stop symbol command (step S330), and the pattern A is set in the variation pattern command (step S332), and the book Exit the routine.

In the embodiment, each variation pattern is set as follows. Pattern A, after starting the variable display of the three symbols L, M, and R on the special symbol display device 40, the left symbol L is stopped after 7 seconds and the right symbol R is changed after 8 seconds. It is set as a pattern that stops and the middle symbol M is stopped after 9 seconds. Pattern B is special symbol display device 4
After starting the variable display of the three symbols L, M, and R of 0 by 0, the left symbol L is stopped after 7 seconds, and the left symbol L when the right symbol R is stopped after 8 seconds. It is set as a so-called normal reach pattern in which the middle symbol M is variably displayed at a low speed for 7 seconds and stopped when the right symbol R matches. The pattern C is set as a so-called super-reach pattern in which the variable display of the middle symbol M is not changed at the stop timing of the middle symbol M of the pattern B but is changed and displayed at high speed for another 5 seconds and then stopped. Pattern D is a so-called special reach that stops at the big hit symbol or at the symbols before and after the big hit symbol after displaying the variation of the middle symbol M at the stopping timing of the middle symbol M of the pattern C at a low speed for another 10 seconds. Is set as a pattern. In the case of super reach and special reach, the three symbols L, M, and R are simply left, middle, and right.
In addition to displaying the variable, a predetermined reach game is played.

In the embodiment, as described with reference to FIGS. 15 and 16, the pattern D is easier to set in the big hit time variation pattern command determination process than in the miss reach reach variation pattern command determination process. In the loose-reach variation pattern command determination processing, the pattern B is easier to set than in the big hit variation pattern command determination processing. That is, the special reach is easily set in the big hit time variation pattern command determination process, and the normal reach is easily set in the lost reach time variation pattern command determination process. By setting in this way, the playability is enhanced and the interest is improved.

In the fluctuation stop process, the CPU 72 of the main control device 70 first determines whether or not it is a big hit (step S230). Here, during the big hit, during the special game displayed on the special symbol display device 40 during the big hit, and during the predetermined time after the end of the special game are included. The predetermined time after the end of the special game is set as, for example, the time required to adjust each state of the pachinko machine 20. If it is determined that it is not a big hit, it is determined whether the variation time in the variation pattern has ended (step S
232). This process is performed by determining whether or not the time has passed, because the change time is set for each change pattern for each change pattern as described in the change start process. When the variable time is over, the stop symbol set for stopping and confirming the variable display is transmitted to the display control device 90 as a confirmation command (step S).
234). Then, it is determined whether or not it is a big hit (step S236), and when it is a big hit, a big hit execution command is transmitted to the display control device 90, the special winning opening driving device 52, etc. (step S238), and this routine is ended. Here, since the jackpot determination in step S236 is performed in the display command determination process (FIG. 14) in step S227 in the variation start process, the determination result may be used, or the execution area of the reserved ball storage area may be used. The determination may be performed using the value of the internal random number counter C1 stored in. It should be noted that when it is determined in step S230 that the big hit is in progress, when it is determined in step S232 that the variation time has not ended, or when step S23 is performed.
When it is judged that it is not a big hit in the big hit judgment of 6,
After the determination, this routine ends.

Next, the operation of the display control device 90 which receives the display command in the process of step S228 in the fluctuation start process of FIG. 9 will be described. FIG. 17 is a flowchart showing an example of a display command execution process executed by the CPU 91 of the display control device 90. This processing is executed when a display command is input from the main control device 70.

In the display command execution processing, first, the current background image displayed on the special symbol display device 40 is input (step S400), and the left background image is input based on the input background image.
A variation mode is set as a variation method of the middle and right three symbols L, M, and R (step S402). In the embodiment, a predetermined timing, for example, a timing every time a predetermined time elapses or a timing at each end of the big hit, is executed by the background diagram changing process (not shown) stored in the program ROM 93.
The background diagrams displayed on the special symbol display device 40 are the background diagrams BG1 to BG at timings such as the timing at which the variable display of the three symbols L, M, and R on the left, middle, and right ends every predetermined number of times.
3 is changed in that order, and the background figure number is written in the VRAM 95.
This can be done by reading the background figure number written in 95. In addition, in the embodiment, the background diagrams BG1 to BG1.
Three symbols L, M, R on the left, center, and right with respect to BG3 are
As illustrated in FIGS. 18 to 20, a variation mode that is imaginatively recalled from the background diagram is set. That is, with respect to the background map BG1 which is a background map of a river having a waterfall in the distance, as shown in FIG. 18, three patterns L, M, R on the left, middle and right
Is set to change so that it falls down a distant waterfall and then rides on the flow of the river. For the background map BG2 which is a background map of a desert having pyramids, an example is shown in FIG. In this way, the variation mode is set so that three patterns L, M, and R on the left, center, and right are drawn out from the sand of the desert, and the cave is formed at the back of the steep left and right walls. With respect to the background diagram BG3, which is a background diagram, as illustrated in FIG. 20, a variation in which the three symbols L, M, and R on the left, middle, and right come out from the back of the cave to the front The mode is set.

When the variation mode set for the background image is set in this way, the variation of the three symbols L, M, R on the left, middle and right based on the variation pattern of the display command and the set variation mode. Start displaying (step S40
4), the process ends. By such processing, the left, middle, and right three symbols in the variation mode set with respect to the background image currently displayed on the special symbol display device 40 in the variation pattern set in the display command determination process of FIG. L, M,
R can be variably displayed. It should be noted that the end of the variable display is the program ROM 93 when the confirmation command is output from the main control device 70 to the display control device 90 in the process of step S234 of the fluctuation stop process of FIG.
The fixed command execution process (not shown) stored in is started, and the stop pattern included in the input fixed command is left,
The variable display is stopped so that the three symbols L, M, R on the center and the right are stopped.

According to the pachinko machine 20 of the embodiment described above, the left, middle and right three symbols L, M and R are variably displayed in a variation mode according to the background figure changed at a predetermined timing. Therefore, the interest of the player can be maintained and the interest can be improved. Moreover, since the variation modes of the three symbols L, M, R on the left, middle, and right are conceptually recalled from the background diagram, the three symbols L, M, left, middle, and right are symbolized. R
Is displayed in a variable manner according to a certain variation mode,
The player's interest can be aroused and the interest can be improved.

According to the pachinko machine 20 of the embodiment, the background patterns BG1 to BG3 are changed, and the three symbols L on the left, middle, and right,
Since the setting of the variation mode of M and R is performed by the display control device 90, the control signal from the main control device 70, that is, the display command and the confirmation command, is the special symbol display device 40.
It is not necessary to consider the background image displayed in.

In the pachinko machine 20 of the embodiment, three background maps BG1 to BG3 are used as the background maps displayed while changing to the special symbol display device 40, but two background maps may be alternately used. It is also possible to use four or more background diagrams. In addition, the pachinko machine 2 of the embodiment
0, the three background diagrams BG1 to BG at a predetermined timing.
3 is changed in this order and displayed on the special symbol display device 40, but three background diagrams BG1 at a predetermined timing.
It is good also as displaying the background figure selected at random among-BG3 on the special symbol display device 40.

In the pachinko machine 20 of the embodiment, the variation mode of the three symbols L, M, and R on the left, middle, and right is conceptually recalled from the background diagram. It does not necessarily have to be ideologically recalled from the background diagram, as it may be changed according to
