The passage is detected by the
The prize balls are paid out (S46).

Then, the number of game balls that have won the special winning opening 16 is counted (S48), and 29 seconds have elapsed since the count reached 10 or the special winning opening 16 was opened (S50). If any one of the conditions is satisfied, the special winning opening 16 is closed and the operation of the condition device ends (S52, S54). However, while none of the conditions is satisfied (“NO” in S50), the open state of the special winning opening 16 is maintained until one of the conditions is satisfied.

In S44, the game ball wins the specific winning opening 18 (S44 "NO", S56 "YES").
Is detected by the specific area switch 92, and 15 prize balls are paid out from the prize ball payout mechanism (S58).
Then, when the game ball is won, the specific area solenoid 96 is operated to temporarily close the specific winning opening 18 (S
60), the special winning opening 16 is closed even if the condition shown in S50 is not satisfied (S62).

Ends. However, if the number of rounds completed here does not reach the predetermined number of rounds (for example, 15) (S64 “N
O)), the condition device is continuously operated, and the game situation is repeated again (S66). When a predetermined number is reached, the operation of the condition device is terminated (S54) and the normal game situation is restored.

FIG. 6 shows a control block diagram of the main control board 70. As described above, the gaming machine 10 is set to operate based on the control of the main control board 70,
The setting of the game status such as the presence or absence of "win" and "big hit" occurrence, the display mode of the symbols displayed on each symbol display device, the setting of the probability in each symbol display device, and the like,
It is set by the main control board 70. The main control board 70 includes a central processing unit (hereinafter, referred to as a “CPU”) 70 a for controlling signals from the respective control boards and switches.
And a memory (hereinafter referred to as “RAM”) 70b for reading and writing control processing data by the CPU 70a.

The CPU 70a is provided with one "random number counter" to determine whether a "big hit" occurs in the special symbol display device 2 and whether a "hit" occurs in the normal symbol display device 6. Various game situations such as are set. That is, the operation of the special symbol display device 2 and the normal symbol display device 6 is set by the “random number counter”.

Here, the "random number counter" will be described. The “random number counter” is used to set a game situation such as the presence or absence and probability of “hit” and “big hit” in the gaming machine 10. The operation is performed by receiving a signal from each of the control boards and switches.
“a” selects one random value from the “random number counter” and stores it in the RAM 70b. The random number stored here is C
The determination is made by the PU 70a, and as shown in Table 2, if the determination value matches the predetermined determination value, a predetermined game situation is set.

[0041]

[Table 2]

For example, when a low probability is set,
When the left and right gate switches 85 and 86 detect the passage of the game ball, the detection signal is transmitted to the main control board 70.
Upon receiving this detection signal, the main control board 70 selects one random number value from the “random number counter” and
It is stored in M70b. Then, the CPU 70a determines the random number value. If the random number value matches one of the random number values set in the “low probability setting” of the “hit” determination value shown in Table 2, the normal symbol display device 6 displays the “hit”. It is determined to occur. However, if they do not match, it is determined that "missing" occurs.

As shown in Table 3, since the random number value of the "random number counter" and the symbol displayed on the ordinary symbol display device 6 are set correspondingly, the occurrence of "hit" in the random number value is performed. And the symbol displayed on the ordinary symbol display device 6 are determined at the same time. Assuming that the "random number counter"
If the random number value selected from is "24", "2"
"4" is a value set as a "hit" determination value as shown in Table 2, and as shown in Table 3 (a), "5" is set in the displayed symbol. A "hit" occurs on the symbol display device 6, and it is determined that "5" is displayed as the "hit symbol".

[0044]

[Table 3]

Further, assuming that the starter switch 90 detects the passage of the game ball when the low probability is set and transmits the detection signal to the main control board 70, the CPU
70a is a "random number counter" simultaneously with the reception of the detection signal.
Is stored in the RAM 70b. Then, this is determined, and if this random number value is “7” (see Table 2)
The occurrence of a "big hit" is determined. Since the "big hit" determination value when the low probability is set is only "7", "missing" is determined when any other random value is stored in the RAM 70b.

Table 3 also shows the combinations of the symbols on each of the symbol display portions 2a, 2b, and 2c displayed on the special symbol display device 2.
As shown in (b), it is set corresponding to the random number value of the “random number counter”. However, the combination of symbols shown in Table 3 (b) is displayed in correspondence with "big hit".
If "miss" is determined, a combination of "miss" symbols set corresponding to the random number value of the "random number counter" is also displayed. The combination of the "losing" symbols is not shown, and the description thereof is omitted.

Further, simultaneously with the determination of the "big hit" or "missing" by the "random number counter", the probability to be set next time is also determined. As described above, if the random number value stored in the RAM 70b based on the operation of the starting port switch 90 matches the “big hit” determination value shown in Table 2, the occurrence of the “big hit” is determined. 2, the high probability judgment value “7, 72, 250, 201, 262, 3”
00 ”is determined. Here, if they match, it is determined that a high probability is set for the normal game situation in which the condition device returns after the end of the operation of the condition device, and a low probability is set if they do not match.

However, when it is determined that "missing" occurs in the special symbol display device 2, even if the high probability is determined, the process is not executed and the currently set probability is switched. Absent. When the occurrence of a "big hit" is determined for the special symbol display device 2, the determined probability is a standby state until the operation of the condition device due to the "big hit" is completed, and the operation of the condition device is terminated. After that, it is set at the same time when the game returns to the normal game situation.

The "random number counter" used here is, as shown in the block diagram of FIG.
One random number counter provided in the PU 70a is also used, and is set so as to repeatedly store and judge a random value every time a predetermined game situation occurs.

FIG. 8 is a flowchart showing the operation of the ordinary symbol display device 6 and the special symbol display device 2. or,
FIG. 9 shows a control operation in the ordinary symbol display device 6, and FIG. 10 shows a control operation in the special symbol display device 2 in a flowchart. As already mentioned,
A game ball passes through one of the left and right gates 20 and 21 (S
100), and the passage of the switch to the left and right gate switches 85, 8
6 (S120 in FIG. 9), and transmits a detection signal to the main control board 70 (S121). Upon receiving this detection signal, the CPU 70a of the main control board 70 (S122)
One random number value is selected from the “random number counter” provided in the RAM 70a and stored in the RAM 70b (S123, S123).
124).

The random number value stored here is determined by the CPU 70a. As shown in Table 2, the determination value used for this determination differs depending on the probability currently set in the gaming machine 10. Then, if the low probability is set, it is determined whether or not it matches the determination value set accordingly (see Table 2) (S125 "YES", S126), and if the high probability is set, It is determined whether or not the value matches the determination value set according to the high probability (S125 “N”).
O ", S126).

As a result of this determination, if it matches any of the determination values shown in Table 2, occurrence of a "hit" is determined in the ordinary symbol display device 6 (S127 "YES"), and at the same time, the symbol of the ordinary symbol display device 6 is determined. The "winning symbol" displayed after the change is completed is also determined (S128). However, if they do not match, the occurrence of a "losing" is determined (S127 "NO"), and at the same time, the "losing symbol" displayed on the ordinary symbol display device 6 is also determined (S129).

Then, as shown in FIG. 8, after these game situations are determined, the ordinary symbol display device 6 starts symbol variation (S102), and has already been determined in S128 (or S129) in FIG. The "winning symbol" or the "missing symbol" is displayed (S10).
4).

Here, a "winning symbol" is displayed, and a game ball wins in the opened starting winning port 14 ("Y" in S106).
ES ", S108" YES ", S110), and as shown in FIG. 10, the starting port switch 90 transmits a detection signal to the main control board 70 (S130, S132). Upon receiving this detection signal, the CPU 70a of the main control board 70 sets (S
134), one random number value is selected from a “random number counter” provided in the CPU 70 and stored in the RAM 70b (S1).
36, S138). At this time, the stored random number value is updated.

Then, the random number value stored in the RAM 70b is determined by the CPU 70a. Here, the determined value also depends on the probability currently set in the gaming machine 10, and if the low probability is set. It is determined whether or not the values match the determination values shown in Table 2 (S140 “YE
S ", S141), if the high probability is set, it is determined whether this also matches the determination value shown in Table 2 (S140" NO ", S142).

Further, it is also determined whether the stored random number value matches the high probability determination value shown in Table 2 (S
144). As a result, when it is determined that they match, it is determined that a high probability is set for the game situation after the operation of the condition device is completed, and that if it does not match, a low probability is set.

Further, if it is determined that the stored random number value matches any one of the "big hit" determination values at each probability ("YES" in S146), a "big hit" is generated in the special symbol display device 2. Is determined, and at the same time, a "big hit symbol" displayed after the symbol change of the special symbol display device 2 is completed (S148).

If it is determined in S146 that they do not match ("NO" in S146), it is determined that "losing" occurs in the special symbol display device 2, and the "losing symbol" displayed at the same time is also displayed. It is determined (S150).
Then, after these are determined, the special symbol display device 2 starts to change as shown in FIG. 8 (S112), and FIG.
The symbol determined in S148 or S150 is displayed (S113).

However, when the "big hit symbol" in S148 of FIG. 10 is displayed, the condition device is activated as described above with reference to FIG. 5 ("YES" in S114, S115).
Then, the operation of the condition device ends and the game machine returns to the normal game situation (S116), and the gaming machine 10 displays the S in FIG.
The probability determined in 144 is set (S117).

When the occurrence of a "losing" is determined on the ordinary symbol display device 6 and the "losing symbol" is displayed in S106 based on this ("NO" in S106), the starting winning port 14 is further set in S108. When a game ball does not win even though it has been opened (S108 "N
O)), and the occurrence of a “losing” is determined on the special symbol display device 2, and based on this, the “losing symbol” is displayed in S 116 (“NO” in S 114).
The game status of various places determined at 0 is invalid, and the probability does not change.

As described above, if one "random number counter" is shared by a plurality of symbol display devices, it is not necessary to provide a random number counter for each symbol display device, and the memory can be used efficiently. Since the "random number counter" is provided on the main control board, the control operation with high operational stability and high reliability in the setting control operation can be performed. Also, as described in the present embodiment, in addition to setting the gaming status of various places, the presence or absence of a symbol changing operation such as "reach state" and its display mode, the occurrence of various game situations and the setting of its operation, etc. Can also be set using a “random number counter”. The “random number counter” used for these settings can be set so as to be shared.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the setting and control method of the "random number counter" to be used, and the increase / decrease and change of the control method and means in the game situation and the contents set by the "random number counter" can be appropriately made. In this embodiment, the "random number counter" is used. However, the present invention is not limited to this, and it is also possible to use a similar one. As a result, it is possible to set and control more diversified game situations and to provide a gaming machine with high expandability.

According to the pachinko gaming machine of the first aspect of the present invention, the operation of the plurality of symbol display devices is controlled by the shared symbol display control means, and furthermore, the symbols are displayed on each symbol display device. If the setting of the symbol display mode and the probability of displaying the predetermined symbol display mode are also controlled by the shared symbol display control means, the plurality of symbol display devices can be controlled by one shared symbol display control means. Since it is controlled and reduction in both the component cost and the operation cost can be expected, it is possible to reduce the cost of the gaming machine.

Then, as in the second aspect of the present invention,
What is determined by the shared symbol display control means is:
Not only the probability, but also the pattern display mode such as the so-called "losing symbol" displayed when the "losing" occurs or the "reach symbol" displayed in the "reach" state, and, further, for the symbol variation required for the symbol variation If the game status of various places such as the time and the opening time of each device is set, the cost of the gaming machine can be further reduced.
