The maximum number of reservations is four.

When the random number storing process (S12) is completed, the condition device process (S13) is subsequently executed. In the condition device processing (S13), when the big hit flag is ON in the big hit flag storage area 52f of the RAM 52,
That is, in the case of a big hit, the big winning opening 16 is opened, closed, and a big hit demonstration display process on the special symbol display device 8 is performed. In the first round of processing, special symbol processing (S
Since the big hit determination process in 14) has not been performed yet, nothing is performed in the condition device process (S13) and the process proceeds to the next process. Next, special symbol processing (S14) is performed.

In this special symbol process (S14), a jackpot determination process and the like which will be described later are performed. Further, when this special symbol processing (S14) ends, next, the normal symbol processing (S
15) is performed. In this normal symbol processing (S15),
Ordinary symbol hit determination described below is performed.

When the normal symbol processing (S15) is completed, next, payout control (S16) for paying out the prize balls is performed and the process returns to S6. Then, in response to the interrupt reset signal from the interrupt reset circuit 57, the CPU 51 repeats the processing from S7 of the main routine shown in FIG. 15 from the start. Therefore, from S7 of the main routine shown in FIG.
This means that the process of S16 is repeated every 2 ms. Special symbol processing of the main routine processing (S14)
If it is determined to be a jackpot state, "1" is stored in the jackpot flag storage area 52f of the RAM 52, the jackpot flag is turned on, and in the next condition device processing (S13), "1" is stored in the jackpot flag storage area 52f. If stored, the special winning opening 16 is opened and closed a predetermined number of times (for example, 15 or 16 times).

Next, details of the special symbol processing (S14) will be described with reference to the flowchart shown in FIG. First, it is determined whether or not a random number is stored (S21).
This determination is made depending on whether or not the number of winning balls stored in the special symbol starting winning number storage area 52d is zero. When the number of winning balls stored in the special symbol start winning number storage area 52d is "0" (S21: NO), the jackpot determination process is terminated and the process returns to the main routine.

The number of winning balls stored in the special symbol starting winning number storage area 52d is not "0", that is, 1 to
If it is determined to be one of 4 (S21: YE
S), the value of each random number stored in the storage area 1 of the special symbol random number storage area 52b is shifted to the determination area and read out, and each is stored in the storage areas 2 to 4 in the special symbol random number storage area 52b. The value of the random number is shifted one by one between the storage areas (S22). That is, the storage value of the storage area 2 of the special symbol random number storage area 52b to the storage area 1, the storage value of the storage area 3 to the storage area 2,
The stored value in the storage area 4 is moved to the storage area 3. Next, the storage number of the special symbol start winning number storage area 52d is subtracted by "1", that is, the number of reserved balls is subtracted (S23).

Next, it is determined whether or not to perform a shortened variation for shortening the time from the variation start of the symbols variably displayed on the special symbol display portions L1, L2, L3 to the fixed display (S24).
This determination is performed based on the number of reserved balls (the number of winning balls for which the jackpot determination has not been performed) stored in the special symbol starting winning number storage area 52d. Specifically, the number of reserved balls is 0
In the case of ~ 2, the shortening fluctuation is not performed (S24: NO),
When the number of reserved balls is 3 or 4, shortening fluctuation is performed (S2
4: YES).

When performing the shortening variation (S24: YE
S), a short time base variation command is output from the main board 41 to the symbol display board 44 (S25). When the shortening variation is not performed (S24: NO), the long-term base variation command is output from the main board 41 to the symbol display board 44 (S26).

2, 2 ", 3:" 3, 3, 3 ", 4:" 4, 4, 4 ",
5: "5, 5, 5", 6: "6, 6, 6", 7: "7,
7, 7 ", 8:" 8, 8, 8 ", 9:" 9, 9, 9 ". The data showing the selected jackpot pattern is RAM
The first stop symbol storage area 52o of 52, the second stop symbol storage area 52p, and the third stop symbol storage area 52q are stored (S31).

In the process of S31, when the value of the special symbol creating random number RN3 is "1, 3, 5, 7, 9", the probability variation mode in which the probability of the next big hit becomes high is entered. "1" is stored in the probability variation flag storage area 52n of the RAM 52, and the probability variation flag is turned on. Also,
The value of the special symbol creation random number RN3 is "0, 2, 4, 6,
When it is 8 ”, the probability of the next big hit is not high and the mode is the normal mode. Therefore,“ 0 ”is stored in the probability variation flag storage area 52n of the RAM 52 to turn off the probability variation flag.

In the determination of S28, if the random number value of the jackpot determination random number RN2 read in S22 is other than "7" which is a jackpot (S28: NO), S
Depending on the value of the reach judgment random number RN6 read out in 22, it is judged whether or not the reach operation is performed (S32). When the value of the reach determination random number RN6 is “20 to 39”, it is determined to be out of reach (S32: YES). When it is determined to be out of reach (S32: YES),
Based on the special symbol creation random number RN3 and the special symbol creation random number RN4 read in S22, the stop symbol of the outlying reach is the first stop symbol storage area 52o, the second stop symbol storage area 52p and the third stop symbol storage area 52 of the RAM 52.

Stop symbol storage area 52o, second stop symbol storage area 5
2p and the third stop symbol storage area 52q are stored (S34). When the processing of S31 or S33 or S34 is completed, next, a symbol designating command for designating a stop symbol to be confirmed and displayed on the symbols of the special symbol display portions L1, L2, L3 is output to the symbol display board 44 (S35). This symbol designating command is the first stop symbol storage area 52 of the RAM 52.
Output based on the stop symbols stored in the o, the second stop symbol storage area 52p and the third stop symbol storage area 52q.

Then, a variation pattern command output process is performed (S35). In this variation pattern command output process, the variation pattern command of the symbol stored in the symbol variation command storage area 52a of the RAM 52 of the main board 41 is output to the symbol display board 44. When the reach variation pattern command is stored in the symbol variation command storage area 52a of the RAM 52, the reach variation pattern command is output from the main substrate 41 to the symbol display substrate 44,
When the reach variation pattern command is not stored, the normal variation variation pattern command is output from the main board 41 to the symbol display board 44 (S35). On the symbol display board 44, based on the variation pattern command received from the main board 41, according to the symbol variation data stored in the ROM 44d, the variation of the symbols of the special symbol display portions L1, L2, L3 of the special symbol display device 8 described later is changed.

Next, with reference to FIG. 19, the operation rate sampling process will be described. The sampling process of the flowchart shown in FIG. 19 is performed by the interrupt reset circuit 57.
2ms when receiving an interrupt reset signal every 2ms from
All the processing is done within this. Therefore, the operation rate sampling process is repeated every 2 ms. When the pachinko machine 1 receives a business start signal indicating that the business of the game hall has started from the game hall management computer 100 (S121: YES),
The business flag is turned on (S122). This business flag is stored in the business flag storage area 52s of the RAM 52 shown in FIG. Further, when a business end signal indicating that the business of the game hall has ended is received from the game hall management computer 100 of the game hall (S123: YES), RA
The in-business flag of the in-business flag storage area 52s of M52 is turned off (S124).

Next, when the in-business flag is ON (S125: YES), the operating number is totaled and the operating rate is calculated (S126). This process is performed as follows. First, from the time when the in-business flag is turned on, the count number of the starting opening switch 72 provided in the starting winning opening 15, the count value of the count switch 75 provided in the special winning opening 16, and the starting winning award. The count number of the starting opening switch 72 provided in the opening 17, the winning opening switch 76 for counting the number of winning balls from the winning opening 19 and the winning opening 20, and the out ball counting switch 77 provided in the out opening 18. The total number of out ball counts (hereinafter, referred to as "total count number") is counted.
This total count number is the number of operations from the start of business on that day to the point in time after the business flag is turned on. Based on this total count number (operating number), the operating rate up to that point is calculated as follows.

The operating rate up to that point is a value obtained by dividing the total count number by the number of game balls that can be launched during the time period from when the business flag is turned on to 100, and then multiplying by 100. Specifically, "operating rate = total count number x 100
/ (Number of shots that can be fired per minute × 60 × the time from when the flag during business is turned on) to that) ”. For example, 1
It is a game machine that can shoot 99 balls per minute, and the flag in operation is ON
If it takes 10 hours and 15 minutes from then, then "operating rate = total number of counts x 100 / (99 x 60
X10.25) ". Next, when the sampling is completed, that is, when the in-business flag is turned off, the sampling is completed (S127: YES). Next, the calculated operating rate and the sampling end signal are output to the game hall management computer 100 (S128).

Next, with reference to FIG. 20, an explanation will be given of the average operating rate calculation processing carried out on the gaming machine management computer 100 side. All pachinko machines installed in the game hall 1
When the sampling end signal is received from (S81), the average operating rate of the gaming hall is calculated based on the operating rate data received from all the pachinko machines 1 installed in the gaming hall (S82). Then, the average operation rate of all pachinko machines 1
(S83).

Next, a second embodiment of the present invention will be described with reference to the flow charts of FIGS. 22 and 23. FIG. 22 is a flowchart of the display switching signal output process executed by the gaming hall management computer 100, and FIG. 23 is a flowchart of the symbol change process executed by the pachinko machine 1. In this embodiment, the gaming machine management computer 100 side determines whether or not to switch the display of each pachinko machine 1, and when switching,
A display switching signal is output to the corresponding pachinko machine 1.

The pachinko machine 1 of the second embodiment is the first
23 is different from the pachinko machine 1 of the embodiment in that the symbol change processing shown in FIG.
22 is different from the first embodiment in the display switching signal output processing shown in FIG. 22, and therefore the different points will be described below with reference to FIGS. 22 and 23.

First, with reference to FIG. 22, a display switching signal output process performed by the game hall management computer 100 according to the second embodiment will be described. When the sampling end signal is received from all the pachinko machines 1 installed in the game arcade (S91), the average operation rate of the game arcade is based on the data of the operation rate received from all the pachinko machines 1 installed in the game arcade. Is calculated (S92). Then, based on the average operating rate, it is determined whether or not each pachinko machine 1 satisfies the setting condition for switching the display (S93). At this time, it is assumed that the standard setting condition is set in advance on the side of the game hall management computer 100.

The conditions preset on the side of the amusement hall management computer 100 include, for example, a value obtained by multiplying the average operating rate by a predetermined coefficient X (for example, 0.8) as a threshold for the operating rate for switching the display. This setting is
From the keyboard 107 of the game hall management computer 100 shown in FIG. 14, a numerical value of a predetermined coefficient X (for example, 0.8) by which the average operating rate is multiplied and a predetermined period (for example, 7 days) are input, and the game is performed. It is stored in the setting condition storage area 112a of the hard disk device 112 of the space management computer 100. The daily operation rate transmitted from each pachinko machine 1 is individually stored in the individual data storage area of the game room management computer 100, and the average daily operation rate of the entire game hall is the average of the hard disk device 112. It is stored in the operation rate storage area 112c.

Here, when a certain pachinko machine 1 has fallen below the threshold of (average operating rate) × predetermined coefficient X (for example, 0.8), which is the setting condition, for seven consecutive days, it is judged in S93. Since it is determined that the setting conditions are satisfied (S93: Y
ES), the display switching signal is output from the gaming hall management computer 100 to the corresponding pachinko machine 1 (S94), and the process is terminated.

Next, the symbol changing process will be described with reference to FIG. FIG. 23 shows the CPU 51 of the main board 41.
It is a flowchart of the symbol change processing performed by. In this symbol change processing, when the pachinko machine 1 receives the symbol change signal from the game hall management computer 100, the background symbol and the special symbol display unit displayed on the display screen 28 of the special symbol display device 8 of the pachinko machine 1 The symbol patterns of the symbols variably displayed in L1 to L3 and the character are switched within a predetermined type range.

Also in the second embodiment, similarly to the first embodiment, the background symbol and the special symbol display portion L1 displayed on the display screen 28 of the special symbol display device 8 of the pachinko machine 1.
It is assumed that the symbol patterns of the symbols that are variably displayed in L3 to L3 and the character are sequentially switched in four ranges of display 1 to display 4. An example of switching the symbol patterns that are variably displayed on the special symbol display portions L1 to L3 is the same as that of the first embodiment.

In this symbol changing process, when the interrupt reset circuit 57 generates an interrupt reset signal, all the processes are performed within 2 ms. First, it is determined whether or not a symbol change signal is received from the game hall management computer 100 (S101).

When the symbol change signal is received from the game hall management computer 100 (S101: YES), E
Referring to the switching count stored in the switching count storage area 56c of the EP-ROM 56 (S102 to S104),
When the count value of the number of switching times stored in the switching number storage area 56c is "4", the display 1 is selected (S
(102: YES), the main board 41 transmits a switching signal to the display 1 to the symbol display board 44 to switch the display screen 28 to the display 1 (S106). When the count value of the number of times of switching stored in the number of times of switching storage area 56c is "3", the display 2 is selected (S102: NO, S103: Y
ES), the main board 41 transmits the switching signal to the display 2 to the symbol display board 44 to switch the display screen 28 to the display 2 (S107). When the count value of the switching count stored in the switching count storage area 56c is "2", the display 3 is selected (S102: NO, S103: NO, S10).
4: YES), the switching signal to the display 3 is transmitted from the main board 41 to the symbol display board 44, and the display screen 28 is switched to the display 3 (S108). When the count value of the switching count stored in the switching count storage area 56c is "1", the display 4 is selected (S102: NO, S103: N).
O, S104: NO), from the main board 41 to the pattern display board 4
A signal for switching to display 4 is transmitted to display 4 to switch display screen 28 to display 4 (S105).

When the display switching is completed, the count value of the switching number stored in the switching number storage area 56c is decremented by "1" (S109), and the switching number storage area 56c is obtained.
If the count value of the number of switching times stored in is not "0", the process returns to the main routine shown in FIG. Further, when the count value of the number of times of switching stored in the number-of-switching storage area 56c becomes "0" (S110: YE
S) After that, the display is not switched, the display remains as it is (S111), and the process returns to the main routine shown in FIG.

As described above, in the pachinko machine 1 of the second embodiment, as shown in FIG. 24, the operating rate of the pachinko machine 1 is the average operating rate of the pachinko machines installed in the game hall. When the threshold value of a predetermined count (for example, 0.8) is continuously lower than a predetermined period (for example, 7 days), a display switching signal is transmitted from the amusement hall management computer 100 to the relevant pachinko machine 1, and the symbol is transferred. The combination of pattern, background image, and character is switched between Display 1 to Display 4, so the display of pachinko machines whose operating rate has decreased because the player has become tired of the time elapsed since installation Can be changed to a new pattern pattern, a background image, or a character, so that it is possible to give the player the impression of a new machine and improve the operating rate. Further, between the display 1 to the display 4, the combination of the pattern pattern, the background image and the character of the pachinko machine 1 whose operating rate is lower than the average operating rate of the other pachinko machines installed in the game hall by a predetermined value, Since the pachinko machine 1 is changed, it is possible to improve the operation rate of the pachinko machine 1 by changing the display of only the pachinko machine 1 having a poor operation rate as compared with other pachinko machines 1.

It is needless to say that the present invention is not limited to a pachinko machine, but can be applied to various game machines provided with a pattern display portion such as a pachi-con machine and a pachi-slot machine. Needless to say, the present invention can be modified in various ways. For example, the display switching may be performed based on the number of operating days per day, not based on the operating rate. For example, if the number of operating days per day falls below a predetermined threshold value (for example, 20000 times (the number of shots is 20,000 balls) for a predetermined period (for example, 7 consecutive days), a combination of a pattern pattern, a background image, and a character is combined. The display may be switched between the display 1 to the display 4. Needless to say, the display is not limited to the four types of the display 1 to the display 4 and can be arbitrarily changed to two types, three types, five types and the like. Also, the pattern pattern, the background pattern and the characters to be displayed are not all switched together, but the pattern pattern and the background pattern and the characters to be displayed may be switched at least one or two. Further, the display 1 to the display 4 may be randomly switched by a lottery.

In the first and second embodiments described above, the display is switched based on the operating rate of the pachinko machine 1, but the reference is not limited to the operating rate, and the game It may be based on the sales of the venue or the rate of customer stagnation. For example, the game hall management computer 100 aggregates the sales of prepaid cards for ball lending installed in the game hall, and if the prepaid card sales do not reach a predetermined reference value for a certain period of time, the game is played. The place management computer 100 may output the display switching signal to the pachinko machine 1. It should be noted that the customer stagnation rate is a count that indicates that the player spends more time playing on a pachinko machine by operating under a lucky number system with one exchange being 100%. Specifically, the customer congestion rate = 100 × the number of suction balls (the number of sales balls when exchanging once) / the number of sales balls until a big hit occurs. Therefore, the game hall management computer 100 may output a display switching signal to the pachinko machine 1 after a certain period of time when the customer congestion rate does not reach the predetermined threshold.

In the first and second embodiments, the average operating rate is multiplied by a predetermined number (less than 1) and compared with the operating rate of each pachinko machine 1. The display may be switched when the difference between the operating rates of the pachinko machines 1 exceeds a predetermined value.
