Here, the processing in the main control board 100 for performing the above-mentioned game by the pachinko machine will be described with reference to FIG.
The description will be made with reference to flowcharts of FIGS. A main processing procedure of the main control board 100 will be described with reference to a flowchart of FIG. 5 showing a main routine.

First, the CPU 102 determines whether or not the power is turned on (S100), and only the first loop immediately after the power is turned on (S100: Yes) proceeds to step 102,
Perform initial settings and end the main routine. Here, if it is determined that the power is not turned on (S100: No), a signal about a winning ball or the like from the winning ball detection switches 218, 220, 222, 224 (see FIG. 4) or the like is input, and another phase is input. Performs input processing to make it usable in (S
200), and output the edited output data to the board relay board 2
10. Output processing for outputting to the payout control board 190 (see FIG. 4) is performed (S300).

Subsequently, the normal symbol operation gate 40 (FIG. 2)
(See S400), a normal symbol starting process, which is a process for a game ball that has passed through, is performed (S400), and a normal symbol / ordinary electric winning control process for changing the symbol of the normal symbol display device 32 is performed along with the gate passing process (S600). ).

Further, a special symbol starting process, which is a process for a game ball passing through the first type starting port 41 (see FIG. 2), is performed (S500). A special symbol change process for changing the symbol of the device 34 is performed (S700). Then, a special winning opening control process for opening the special winning opening 51 according to the occurrence of a hit is performed (S8).
00).

Subsequently, a lamp and LED lighting process is performed (S104). Finally, the audio output processing for outputting the audio via the audio control device 170 proceeds (S106).
The main routine processing of the cycle is completed. In the main routine, the reset signal from the built-in clock
It is repeated for each machine cycle added to U102.

Next, the change processing of the special symbol display device in the above-described step 500 shown in FIG. 5 based on the winning of the first kind starting port 41 or the above-mentioned ordinary electric accessory 42 will be described with reference to the subroutine of FIG. This will be described in detail.

First, the CPU 102 determines whether or not a game ball has won the first-type starting port 41 based on a signal from the first-type starting port switch 202 (S502). (S502: No), the special symbol start subroutine ends. On the other hand, when the game ball has won (S502: Yes), it is determined whether the start storage variable U is less than 4 (S504). Here, the variable U indicates the number of game balls that have won the first kind opening 41 during the symbol change on the special symbol display device 34, and in this embodiment, the number exceeding 4 is held as described above. It is configured not to be. Therefore, when the variable U is 4 (S504: N
o), the subroutine ends.

On the other hand, if the variable U is less than 4, (S50
4: Yes), and after adding 1 to the variable U (S506), the current timing in the symbol selection random number of 626 frames from 0 to 625 shown in FIG. 9 (when a game ball wins to the first type starting port 41) Is extracted and stored (S508). As described later, in the present embodiment, when the probability is low, the random number value “19” is set.
2 "and a random value" 433 "are set as a jackpot, and a jackpot occurs with a probability of 2/626. At a high probability, the random numbers" 2 "," 50 "," 98 "," 192 ",
"243", "291", "339", "387",
“433” and “484” are set as big hits, and big hits are generated with a probability of 10/626. As a result, the subroutine of the special symbol starting process ends.

Next, the special symbol changing process in step 700 of FIG. 5 will be described with reference to the flowchart shown in FIG. Here, the processing when the game ball does not win the first type starting port 41, that is, when the variable U is 0 will be described. First, the CPU 102 determines whether the symbol of the special symbol display device 34 shown in FIG. 3 is changing (S7).
02) Here, since the special symbol display device 34 is not changed (S702: No), it is determined whether the variable U is “1” or more (S718). Here, since the variable U is 0 (S718: No), the subroutine of the special symbol variation process ends.

Next, a description will be given of a process when a game ball wins in the first kind starting port 41 and the variable U becomes 1. Step 702 whether the special symbol display device 34 is being changed
Is negative, and the CPU 102 determines that the variable U is “1”.
It is determined whether or not this is the case (S718). Since the variable U is 1 (S718: Yes), “1” is subtracted from the variable U (S720). And the change of the symbol of the special symbol display device 34 is started (S722).

Thereafter, the CPU 102 determines whether the high probability flag indicating the high probability state is on (S72).
4). Here, in the low probability state (S724: N
o), the random value set in step 508 described above is
It is determined whether the random number value of the jackpot is “192” or “433” (S734). If the random number value is “192” or “43”
In the case of 3 "(S734: Yes), after setting the jackpot flag (S736), it is determined whether or not the specific jackpot (random number value 433) is shifted to the high probability (S738). In this case, (S738: Y
es), and turns on a high probability flag indicating a high probability state (S7).
40), and proceed to S742. On the other hand, when the random number value is not the specific jackpot (S738: No), the process proceeds to S742.

In S742, it is determined whether the random number is a value for performing long reach. Here, when a big hit occurs, the random number value “192” or “43” for performing long reach is set.
Since it is 3 "(S742: Yes), the flow shifts to S748 to set the long reach fluctuation mode as the mode at the time of stopping (S748). Thereafter, the special figure fluctuation timer for setting the fluctuation time of the special symbol is started ( S754).

If it is determined that the high-probability flag is ON in S724, the random number value is 333 under the high probability.
"2", "50", "9"
8 ”or“ 243 ”(S72).
6). Random numbers are “2”, “50”, “98”, “24”
In the case of "3" (S726: Yes), the obtained random number value is replaced with "192" for generating a non-specific jackpot of 333 (S728), and the process proceeds to S734. If the random number is not "98" or "243" (S726: No), the random number value becomes 7 under high probability.
“291”, “33” which generates 77 specific jackpots
It is determined which of “9”, “387” and “484” (S726) the random number is “291”, “339” or “3”.
87 ”and“ 484 ”(S730: Yes),
The obtained random number value is replaced with “433” that generates a specific jackpot of 777 (S732), and the flow shifts to S734. On the other hand, when the random numbers are “291”, “339”, “38”
7 ”and“ 484 ”(S730: No),
The process moves to S734.

On the other hand, if the determination of the big hit in S734 is No, it is determined whether or not the random value to be lost is a random value for performing the above-described reach variation (S744).
If the reach fluctuation is not performed (S744: N
o), a loss variation mode is set as the mode at the time of stop (S752). After that, the special figure fluctuation timer which sets the fluctuation time of the special symbol is started (S754).

On the other hand, when the losing symbol is in the reach mode, the determination in S744 is Yes, and it is determined whether the random number value is a value for performing long reach (S742). Here, in the case of long reach (S724: Yes), the process proceeds to S748 described above. On the other hand, if it is not long reach (S742: No), it is determined whether the high probability flag indicating the high probability state is on (S746). Here, in the high-probability state, the reach reach is not normally changed, so that if the high-probability flag is set (S74
6: Yes), and proceeds to S752 to set the loss variation mode. On the other hand, if the state is not the high probability state (S74
6: No), the normal reach fluctuation mode is set as the mode at the time of stop (S750). Thereafter, a special figure fluctuation timer for setting the fluctuation time of the special symbol is started (S75).
4).

When the symbol change of the special symbol display device 34 is started in the above-described step 722, in the next machine cycle, in the judgment in step 702, it is determined whether the symbol is being changed, and the CPU 102 first determines whether the symbol is being changed. It is determined whether the symbol variation timer set in S754 has timed out (S704). Here, until the symbol stop timer times out due to the elapse of the fluctuation time (S704: No), the fluctuation of the symbol is continued (S71).
6).

When the symbol variation timer times out (S704: Yes), the CPU 102 stops symbol variation in each variation stop mode (S706). That is, when a normal loss that is not the reach mode is set,
Normal symbol stop is performed, and when long reach and normal reach are set, symbol fluctuation is stopped in the reach mode.

The special winning opening control process in step 120 of FIG. 5 will be described with reference to a subroutine shown in FIG. First, after judging whether the big hit flag is set (S801: Yes), it is judged whether the big winning opening is open (S802). Since the big winning opening is not open in the first operation (S802: No), Go to step 804,
Judge whether it is the interval time after opening. In the first case, since it is the interval time after the determination that the big hit is determined (S8
04: No), the process proceeds to step 806, and it is determined whether R = 16. Here, R is incremented by +1 when passing through a specific area after the end of 1R in the number of rounds. Since R = 0 at this point (S806: No), step 80 is executed.
Proceeding to step 8, it is determined whether the interval time timer has expired after the determination. Here, the post-judgment interval time is the time from when the big hit is determined to when the big winning opening is opened. When the set time is reached (S808: Ye
s) The process proceeds to step 810 to issue a special winning opening command and open the special winning opening.

In the next machine cycle, step 8
In step S802, it is determined whether the special winning opening is open or not. Since the special winning opening is now open (S802: Yes), step 8 is performed.
Proceed to 12. In step 812, it is determined whether the special winning opening time timer has expired. Here, since the big winning opening has just been opened (S812: No), the process proceeds to step 816. In step 816, the count SW:
Determine whether it is ON. Here, if it has not passed through the count switch (S816: No), the process ends.
On the other hand, if it has passed (S816: Yes), the process proceeds to step 818, and it is determined whether R = 15. Here, since the opening of the special winning opening is the first (S818: No), the process proceeds to step 820, and it is determined whether the specific area SW is ON. In this step 820, if the game ball has passed through the specific area when winning in the special winning opening 51 (S820: N
o), proceeding to step 822, if not passing (S)
820: Yes), and proceed to step 824. Here, the description is continued assuming that the vehicle has passed (Step 820: Ye
s). With the passage, the specific area SW is turned on (S822). Next, it is determined whether or not the count number is ≧ 9, that is, whether or not approximately nine game balls have won the special winning opening. If the winning count reaches 9 due to the winning in the big winning opening (S824: Y
es) The process proceeds to step 826 to issue an instruction for a special winning opening closing command and close the special winning opening 51 once. And
Proceeding to step 828, it is determined whether the specific area SW is in the ON state. Here, since it is in the ON state as described above (S828: Yes), Step 8
Proceeding to 30, the specific area SW is turned off. Subsequently, the process proceeds to step 832, where the count of winning the special winning opening is reset, and then the process proceeds to step 834, where R = R
Set to +1. As described above, R indicates the number of open rounds, and if the special winning opening is closed and the specific area SW is ON, it is counted as one time.

In the next machine cycle, since it is the interval time after release at step 804, which is the interval time after release (S804: Yes), the process proceeds to step 846. When the interval time after the opening has reached the timer time-up (step 846: Yes), the process proceeds to step 810, and the special winning opening is opened again.

Next, the flow of processing when the opening of the special winning opening is repeated 16 times will be described. In the 16th round, the number of consecutive winning openings has been 15 times so far, so R =
It becomes 15. First, it is assumed that the special winning opening is open (S8
02: Yes), the process proceeds to step 812, and until the special winning opening time timer expires (S812: N).
o), the process proceeds to step 816, and if it is determined that the count SW is ON, the count SW is passed (S81).
6: Yes), proceed to step 818 to determine whether R = 15. Here, since R = 15 (S81
8: Yes), the process proceeds to step 824 without turning the specific area SW on. By determining that the count number ≧ 9 in step 824 (S824: Yes),
Proceeding to step 826, the instruction of the special winning opening closing command is output, and then proceeding to step 828, where the specific area SW is
It is determined whether the state is N. As described above, R = 15, and the specific area SW is not in the ON state (S8).
28: No), proceed to step 836 to make R = 16.

In the next machine cycle, step 802
In the determination of whether or not the special winning opening is open, the current state is that the final round has been completed (S802: N
o), proceed to step 804; Since it is determined in step 804 whether the interval time is after opening, the current state is that the big hit ends and the end delay time is entered (S804: N
o), proceed to step 806. Since it is R = 16 at the present time in the determination of whether or not R = 16 in step 806 (S806: Yes), the process proceeds to step 848, and it is determined whether or not the end delay time timer is up. Here, if the time is not up (S848: No), the process ends. On the other hand, if the time is up (S84
8: Yes), proceed to step 850 to reset R, turn off the big hit flag (S852), turn off the high probability flag (S854), and end the process.

In this embodiment, the special symbol display device has been described as a representative. However, in practice, a random number of 1 may determine whether or not a normal symbol is a stop symbol.

In the above-described example, an example is described in which the variation process of the special symbol display device directly connected to the player's profit is selected using a random number of 1. However, one that is not related to the player's profit is selected. It is also possible to select using a random number of. For example, when displaying a story in which a hero defeats a monster during a jackpot or opening screen display, the content of the story can be determined using a random number of 1. In the first story, the hero gets weapons from the king. The weapon branches when it receives a sword and when it receives an ax. The second branch is where the monster is a dragon or a demon. It branches when fighting a dragon and when fighting a demon. The first and second branches are selected by a random number of 1. At this time, there are four random numbers, and if the random number is 0, the sword is obtained to fight the dragon. If the random value is 1, get a sword and fight the demon. In the case of a random number of 2, the player gets an ax and fights the dragon. In the case of the random number value 3, it is possible to set, for example, to obtain an ax and fight the demon.
