Is released, the specific area winning port 18 is simultaneously opened (S52).

When a game ball falls into the opened special winning opening 16 (S54 "YES"), the passage is detected by the special winning opening switch (counting switch) 91 and 15 winning balls are paid out. Is performed (S56). Here, the number of gaming balls dropped into the special winning opening 16 is counted (S58), and when the counted number reaches ten, or 29 seconds have elapsed since the special winning opening 16 was opened (S60 "YE").
S "), the special winning opening 16 is closed (S62). Then, the operation of the condition device ends and the "big hit" operation ends (S64).

However, when the number of game balls winning the large winning opening 16 is less than 10 and 29 seconds have not elapsed since the game balls were opened (S60 “NO”, S70 “NO”), these are set. Until the condition is satisfied, the open state of the special winning opening 16 is maintained.

Here, as shown in S54, the game ball is provided in the special area winning opening 18 provided inside the special winning opening 16.
(S54 "NO", S70 "YES")
The passing is detected by the specific area switch 92, and based on the detection signal, the specific area solenoid 99 is operated to close the specific area winning opening 18 (S72), and 15 prize balls are paid out (S74). ). Then, with the winning in the specific area winning opening 18, the accessory continuous operating device is activated.

When the accessory continuous operation device is operated, the special winning opening 16 is closed once regardless of the number of winning balls and the opening time of the game balls into the special winning opening 16 shown in S60 (S7).
6), one of the number of continuous operations set in the condition apparatus.
The round ends. The maximum number of continuous operations of this condition device is set to 16 times, and when the number of times the large winning opening 16 closed in S76 is less than 16 times (S78).
(“NO”), that is, if the number of consecutive operations is less than 16, the special winning opening 16 and the specific area winning opening 18 are opened again (S50, S52), and the above-mentioned gaming situation is repeated.

However, when the number of continuous operations has reached 16 as shown in S78 (S78 "YES"), the operation of the condition device ends and the "big hit" ends (S6).
4). In this way, if a game ball wins the winning opening 18 while the specific area winning opening 18 is open, the condition device operates continuously, and if no winning wins, the "big hit" ends in that round.

You.

As described above, the variation pattern is configured by combining the 13 types of variation shown in Table 3, and the variation operation in the special symbol display device 2 is set by further combining the variation patterns. This fluctuating operation is roughly classified into a case where "reach" appears and a case where it does not appear. When the "reach" does not appear, that is, all the changed symbols 2a, 2b, and 2c display different symbols. In the case of “missing”, as shown in Table 5, “fluctuation pattern 1” appears, then “fluctuation pattern 2” appears (at the highest probability, “fluctuation pattern 3” appears), and “fluctuation pattern 23” appears. Configured to appear.

Further, as shown in Table 5, 32 types of operations in which the “reach” appears are set, and each “reach” operation is determined by the lottery probability and the “slip operation” of the special symbol display device 2. , And the presence / absence of the “re-fluctuation operation”.
Table 6 shows the presence or absence of the operation content in these fluctuating operations according to the lottery probabilities.

[0081]

[Table 6]

FIGS. 20 and 21 show the special symbol display device 2.
FIG. 3 is a block diagram showing a main control processing structure according to FIG. As shown in the figure, the control processing is composed of subdivided control processes (programs) each having a hierarchical structure, and a higher-level control process (program) successively calls a lower-level control process (program) to execute each process. Is performed in accordance with. These control processes (programs) are configured to operate according to control instructions from the main control board 70.

FIG. 22 is a block diagram showing a control processing operation in the special symbol display device 2. As shown in the figure, when the first-type start-up switch 90 detects that a game ball has fallen into the first-type start winning opening 14, the "switch determination process" shown in FIG.
And "special symbol random number", "big hit symbol random number", "reach random number" and "pause symbol random number"
In the "big hit random number storage area" provided in the RAM. Then, a “big hit” determination, a “stop symbol” determination, a “reach operation” determination, a “re-variation operation” determination, and a “big hit notice” determination are made from the stored random numbers.

The "big hit" determination is performed in the "special symbol change standby process" in the "special symbol display process" shown in FIG. In the standby process, “7” if the value stored in the “big hit random number storage area” from the “big hit random number” is the lowest probability, and “7” if the value is the highest probability.
If any of “71”, “107”, “173”, “227”, and “307”, a “big hit” occurs. When this "big hit" occurs, "AAH" is stored in the big hit determination data in the "special symbol change waiting process".

Further, the "stop symbol" is determined by determining a different stop symbol depending on whether "losing" or "big hit" is determined based on the value stored in the "big hit random number storage area". It is determined. Here, when it is determined to be "out", the value stored in the "big hit random number storage area" from the "special symbol random number" is set as a stop symbol. However, if the value matches the "big hit" symbol shown in Table 2, the "reach selection process" shown in FIG.
And the content of the left symbol 2a in the stop symbol and "+1"
The data selected from the symbol (one symbol destination of the "big hit" symbol) loss creation table "is set as the stop symbol of the middle symbol 2c. Table 7 shows the "+1 symbol loss creation table". Note that the symbol numbers described in the table correspond to the symbol numbers shown in Table 1.

[0086]

[Table 7]

When the "big hit" is determined, the "big hit" is further determined by the specific symbol shown in Table 2 (b).
It is determined whether or not the symbol has been generated successively. If the symbol has not been generated, a symbol is selected from the “special symbol jackpot table” shown in Table 8 (a).
A symbol is selected from the "special symbol normal jackpot table" shown in FIG. Further, the selected stop symbol is stored in each stop symbol number protection area.

[0088]

[Table 8]

However, if the “reach M0, M1” shown in Table 5 occurs in the “re-variation operation determination process” shown in FIG. 20, or the “big hit” in the normal symbol shown in Table 2 (a) Occurs, or the "big hit" occurs while the "big hit" occurs in the specific symbol shown in Table 2 (b).
Is not generated four times in a row, a symbol is selected from the "re-variation operation transition symbol 1 table" shown in Table 9 (a). When the "big hit" occurs four times in a row, a symbol is selected from the "re-variation operation transition symbol 2 table" shown in Table 9 (b).

[0090]

[Table 9]

Next, the "reach operation" decision is made according to FIG.
Left symbol 2 in the "special symbol change standby process" shown in FIG.
This is performed when the stop symbol of a and the right symbol 2b are the same, or when "big hit" occurrence is selected. The “reach operation” is performed by first stopping symbol combinations determined in the “reach selection process” and the “special symbol change standby process”.
The “reach selection table” is determined from the “probability change flag” in the above. Then, the "reach operation" (reach variation pattern) is selected from the "reach selection table" and the "reach random number" using the value stored in the "big hit random number storage area".

The "reach operation" (reach variation pattern) is set differently depending on the gaming situation such as the lottery probability relating to the special symbol display device 2 and whether or not a "big hit" occurs. Then, according to the combination of the stop symbols and the "probability variation flag", the "reach before and after the lowest probability medium and large hits", the "reach after the lowest probability medium and large hits", the "reach after the highest probability medium and large hits", the "reach with the lowest probability medium and large hits" and the "highest" The table shown in Table 10 is selected for each of the "reach probability medium and large hits reach", "reach reach other than before and after the lowest probability medium and big hits" and "reach reach other than after the highest probability medium and large hits". It should be noted that "before the big hit" described in the table indicates a symbol one symbol before the "big hit" symbol, and "after the big hit" indicates one symbol ahead of the "big hit" symbol.

[0093]

[Table 10]

Then, the "reach selection table" selected by the combination of the stop symbols shown in Table 10 and the value stored in the "big hit random number storage area" from the "reach random number" are used as the "reach operation" (reach variation pattern). Is determined. The reach selection table shown in Table 10 is shown in Table 1.
1 to Table 13. As described above, the reach operation (reach variation pattern) appearing on the special symbol display device 2 and the selection of the symbol variation pattern in which “reach” does not occur are determined by the random number value stored in the “big hit random number storage area”, Further, a variation pattern corresponding to the “probability variation flag” and the “reach selection table” selected based on the random number value is selected and appears.

[0095]

[Table 11]

[0096]

[Table 12]

[0097]

[Table 13]

In the "re-variation operation" determination, a "big hit" has occurred in a normal symbol other than the "reach D5, D6, M0, M1" in the "re-variation operation determination process" shown in FIG. In the case where the “reach flag” is set, if the numerical value stored in the “big hit random number storage area” from “reach random number” is an odd number and a “big hit” occurs in a specific symbol other than “reach D5, D6, M0, M1” Bit 6
Is set to “ON”.

FIG. 23 is a time chart ((a) display of big hit notice, (b) big hit notice timing) showing the above-mentioned "big hit notice" decision. As shown in FIG. 23 (a), the special type display device 2 starts to fluctuate when the first-type start-up switch 90 detects the passage of a game ball, and the special type display device 2 starts to fluctuate. A lottery is performed at the same time as the symbol displayed in the "big hit", "losing reach", or "losing" is determined (in the figure), and if the lottery is won, the "big hit notice" is obtained until the time in the figure.
Is displayed.

The "big hit notice" is performed when a specific character, background, or the like appears in the symbol display area 2d shown in FIG. 2 while the special symbol display device 2 is changing.
Five types of “big hit notice” are set, and the contents of the notice are shown in Table 14. It should be noted that the “big hit notice D” in the “big hit notice” appears only when the lottery probability is the lowest probability, and the other “big hit notice” appears regardless of the lottery probability.

[0101]

[Table 14]

If the symbol displayed on the special symbol display device 2 is "big hit" or "losing reach", the lottery is selected in the "reach selection process" shown in FIG. If the result is "missing", a lottery is performed in the "special symbol change waiting process".
In this lottery method, if it becomes "Big hit", "Large reach after big hit", "Large reach before big hit", "Large reach other than before and after big hit", and "Large that does not reach" 5 cases are set.

If the lottery probability is the lowest probability, the lottery in the case of the "big hit" is determined from the lowest probability medium-large hit reach selection table as shown in Table 15 (a) as shown in Table 15 (a). As shown in b), a "big hit notice" is randomly selected from the highest probability medium / big hit reach selection table and the "reach" random number using the value stored in the "big hit random number storage area".

[0104]

[Table 15]

[0105] In the case of the "reach after the jackpot", if the lottery probability is within the minimum probability, the table 1
6 (a) from the “lowest probability +1 symbol loss reach selection disable”, and from the “highest probability +1 symbol loss reach selection table” and the “reach random number” shown in Table 16 (b) if the maximum probability is in effect. The lottery is performed using the value stored in the "big hit random number storage area".

[0106]

[Table 16]

Next, in the lottery in the case of the “reaching before the jackpot”, if the probability is the lowest probability, the “lowest probability medium—one symbol (one symbol before the large symbol) shown in Table 17 (a) is shown.
From the "leakage reach selection table", if the probability is "highest probability", then if the "reach reach other than before and after the big hit" is the lowest from the "least reach selection table during the highest probability" and the "reach random number" shown in Table 17 (b), Table 18 during probability
"Lost probability out-of-reach reach selection table" shown in (a)
Therefore, during the highest probability, the lottery is performed using the values stored in the "big hit random number storage area" from the "reach reach selection table during the highest probability" and the "reach random number" shown in Table 18 (b).

[0108]

[Table 17]

[0109]

[Table 18]

In the case of “outside of reach,” the “reach random number” is replaced by the “big hit random number storage area”.
If the value stored in is "0" to "5", the winner is won,
"Big hit notice A" shown in Table 14 is performed. In this case, "1" is stored in bit 0 to bit 2 of the "reach flag" in the "special symbol change standby process" shown in FIG. 20, and the start of the "big hit notice" is set.
As described above, in the case of the "big hit" or "losing reach", the start setting of the "big hit notice" is as shown in Table 1.
This is performed by setting a “reach flag” as shown in FIG. As described above, the setting of the “big hit notice” is configured so that the lottery is performed using the value stored in the “big hit random number storage area”.

FIG. 24 is a time chart showing the opening / closing operation of the special winning opening 16, which is a first-class special electric accessory. As described above, when the symbol of the special symbol display device 2 is determined and a "big hit" occurs, the condition device is activated. When the "big hit" is determined, the display time at the start of operation of the condition device is also set. It is configured to maintain the closed state of the special winning opening 16 until the display time elapses (A).

The display time at the start of operation is determined by counting down the "display time at the start of operation of the conditioner" set in the "special symbol control process" and the "special symbol control timer" shown in FIG. This is performed by detecting that it has become "0" in the "condition device operation start process" shown in FIG. The display time at the start of operation set here is a 3912 interrupt (7824 ms), and the display time is configured to be set in the “special symbol control timer”.

When it is detected that the count value of the “special symbol control timer” has become “0”, the first opening time 14500 in the special winning opening 16
The interruption (29000 ms) is set in the "special symbol control timer", and the special winning port 16 and the specific area winning port 18 are opened (B).

The opening of the special winning opening 16 is performed by setting the bit of the “solenoid board buffer” to “ON” in the “winning opening processing” shown in FIG. This is done by outputting. The first opening time of the special winning opening 16 (14
500 interrupts 29000 ms) is counted down, and during this time, if 10 game balls win in the special winning opening 16 or the counted-down value becomes “0”, the pause time (750 interrupts 1500 ms) of the special winning opening 16 is set to the aforementioned value. The "special symbol control timer" is set, and the special winning opening 16 is closed.

When the pause time of the special winning opening 16 is set, the countdown starts at the same time, and until the countdown value is determined to be "0" in the "winning stop process" shown in FIG. During this time, the special winning opening 16 maintains the closed state (C). Here, the count value is “0”.
Further, when the game ball falls into the specific area winning opening 18 and the operation of the accessory continuous operation device is detected, the opening time of the special winning opening 16 is interrupted again to the "special symbol control timer" by 14500 interruption (29000 ms). Set, and this is the second time ~
The opening time of the 16th special winning opening 16 is set. However,
If the operation of the accessory continuous operation device is not detected,
"Time at the end of operation of condition device" 517 shown in FIG.
6 interrupts (10352 ms) for "special symbol control timer"
Set to.

When the condition device is operated, the countdown of the "condition device operation end time" is started after one interruption (2 ms). The special winning opening 16 is configured to maintain the closed state (D) until the countdown value reaches “0”.

FIG. 25 is a time chart showing the operation of the accessory continuous operation device. The continuous action device activates the condition device, opens the special winning opening 16 and sets the operation start of the solenoid 99 for the specific region, and detects the passage of the game ball by the switch 92 for the specific region when the condition device is activated. To start the operation.

That is, the specific area solenoid 99 is activated only when the bit 7 of the “solenoid board buffer” in the “switch determination processing” shown in FIG. Since the game ball is released, if the passage of the game ball is detected by the specific area switch 92 provided in the specific area winning port 18 and it is determined that the special winning port 16 is open or during the pause time. By turning on the "big hit operation buffer" bit in the "switch determination process", the operation of the accessory continuous operation device is started.

The continuous operation device for the accessory does not set the bit 7 of the “solenoid buffer” to “ON” after 25 interruptions (50 ms) when the passage of the switch 92 for the specific area is detected, and the operation of the solenoid 99 for the specific area is performed. Is completed, and the specific area winning port 18 is temporarily closed. If the game ball has fallen into the winning opening 18 while the specific region winning opening 18 is being opened, the above setting is repeated.

When the number of times of operation of the accessory continuous operation device ends 16 times, the "big hit operation buffer" in the "winning stop process" shown in FIG. 21 is cleared, and the operation ends. However, if the game ball does not win in the specific area winning opening 18 while the specific area winning opening 18 is open, the "solenoid board buffer" in the main program shown in FIG. 20 is cleared to clear the solenoid for the specific area. The operation of 99 is ended, and the specific area winning opening 18 is closed.

As described above, the opening and closing of the special winning opening 16 and the specific area winning opening 18 are configured so that a plurality of programs provided on the main control board 70 interact with each other and operate by these control processes.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, increase / decrease of the reach fluctuation pattern that appears, increase / decrease of the game condition and selection table for selecting the fluctuation pattern, timing of displaying the “big hit” in advance, a method of the advance notice, and the role associated with the occurrence of the “big hit” It is possible to increase or decrease the setting content of the continuous object operating device, change the setting time, and the like as appropriate, and thereby more efficient control processing can be performed, so that a responsive and highly reliable gaming machine is provided. it can.

[0123]

According to the pachinko gaming machine of the first aspect of the present invention, a plurality of symbol variation patterns displayed on the symbol display device are set, and any of these symbol variation patterns is displayed. Is selected and displayed based on the control processing by the main controller. Since the symbol variation pattern selected here is selected based on the game situation that occurs during the game, the program efficiency is improved by operating based on the main control board that controls and processes these large game situations. Good responsiveness. As a result, it is possible to set a symbol variation pattern that can respond to more various game situations.

The symbol variation pattern includes a plurality of reach symbol variation patterns in which a reach state appears, and the reach symbol variation pattern has the lowest probability and the highest probability of the lottery probability. It is preferable that a different symbol variation pattern appears depending on whether a slip has occurred and whether or not a reach state has occurred, as in the third aspect of the present invention. If the symbol variation pattern that appears in this way is set differently for every game situation, it is possible to prevent the game situation from becoming monotonous and to provide an effect of giving a sense of expectation to the game.

In the switching setting of the symbol variation pattern, if the setting is controlled by using a pattern data table as in the fourth aspect of the present invention, the control process can be performed efficiently. The required memory can be reduced, and the operation efficiency of the program is good. Also, for example, in the case of a partial change of the symbol variation pattern, the program can be easily shifted since the table may be changed.

Further, as in the invention according to the fifth aspect, after detecting an interrupt processing to the main control unit, the main control unit instructs and displays a "big hit notice" for notifying a "big hit" on the symbol display device. good. Since the main control unit issues control instructions for various operations in the gaming machine, efficient control processing can be performed by performing control processing of "big hit notice" with the main control unit.

The opening and closing of the special winning opening and the specific area winning opening are set in accordance with the drop of the game ball into the special winning opening and the specific area winning opening. If these settings are set and controlled by the main control unit, the control processing efficiency is improved, and the control processing is not performed through a plurality of control devices. Opening and closing operations of the winning opening and the like are performed smoothly.
