BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko machine equipped with control means such as a microcomputer.

[0002]

2. Description of the Related Art For example, a pachinko machine, which is a kind of ball game machine, has recently become popular in which an electric display device such as a liquid crystal display device is provided in the center of a game board. In this electric display device, a plurality of symbols (hereinafter referred to as "special symbols") represented by images are variably displayed, and three rows of rotating reels of the slot machine are pseudo-displayed. When the variable display of special symbols is stopped in a predetermined stop mode (a stop mode in which three identical special symbols are gathered), the so-called "big hit"
Then, the special game state, which is advantageous to the player, is entered. In general pachinko machines, the variable display of special symbols is started on the condition that the game balls launched into the game board by the operation of the launch handle enter a predetermined winning opening (hereinafter referred to as "starting winning opening"). , The special symbol is stopped and displayed after a predetermined time has elapsed.

In such a pachinko machine, when a predetermined condition is satisfied (for example, when a specific stop mode in which three specific special symbols are arranged is provided), the transition probability to the special game state is relatively high. There is a gaming machine that is supposed to generate a high state (hereinafter referred to as a "high probability state"). For example,
The transition probability to the special game state in the normal state is 1/33
However, the probability of transition to the special game state in the high probability state fluctuates to 5/335, which is five times that in the normal state. Such a pachinko machine generally has a "probability change machine (or probability change machine)" because the transition probability to the special game state changes.
It is called.

[0004]

However, in such a pachinko machine, the high-probability state continues until the next big hit occurs (determination of transition to the special game state), or the number of games to be continued is predetermined. ing. Therefore, even if a high probability state occurs, the player's interest has already shifted to the next big hit occurrence, and for the game during the high probability state, the player can play the game almost the same as the normal state. Just continue. That is, the game in the high probability state lacked interest.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ball game machine in which the player's interest in a game in a high probability state is increased and the game in a high probability state is interesting.

[0006]

The ball-playing machine of the present invention,
Display means for performing variable display of special symbols indicating transition to special gaming state and display relating to game when stopped in a predetermined stop mode, and predetermined probability of transitioning to special gaming state in response to a predetermined input signal In a ball game machine having a control means for controlling the variable display of the special symbol according to the result of the determination, the occurrence of a high probability state in which the probability is relatively high and the continuation of the high probability state. The present invention is characterized in that a probability variation lottery means for determining the number of times to perform by a lottery is provided. The number of times
For example, it is counted as once from the start of the variable display of the special symbol to the stop thereof.

The lottery by the probability variation lottery means is executed, for example, when the number of times determined in the previous lottery has expired or every predetermined number of times.

In the embodiment of the present invention, when the random fluctuation lottery means performs the lottery, if the number of times determined in the previous lottery has not expired, the remaining number of times is selected in the current lottery. It shall be added to the determined number of times.

In another embodiment of the present invention, the display means is
When a lottery is performed by the probability variation lottery means, a display indicating the result of the lottery is displayed. Further, in the case where the random fluctuation lottery means performs the lottery every predetermined number of times, the display means does not expire the number of times determined in the previous lottery when the random fluctuation lottery means performs the lottery. Will display that the high probability state will continue even if the continuation of the high probability state is not determined in the current lottery.

[0010]

According to the ball game machine of the present invention, the occurrence of a high-probability state having a relatively high transition probability to the special game state and the number of times the high-probability state continues are determined by lottery. It is possible to give the player the thrill and expectation of how long the high-probability state, which is advantageous to the player, will continue. As a result, the game in the high probability state is more interesting, and the player can be motivated to continue the game.

If the lottery in the probability variation lottery means is to be executed when the number of times determined in the previous lottery has expired, even if the high-probability state ends, the player is informed of the state. You can have a sense of expectation to continue. In addition, the player can enjoy the thrill and expectation as to whether or not the high-probability state continues each time the high-probability state ends. Also, if the high-probability state continues, the game is continued, and if the high-probability state does not continue, stop the game. can do.

Further, in the case where the lottery by the probability variation lottery means is executed every predetermined number of times, the player determines whether the high probability state continues every time the number of times of continuation of the high probability state reaches the predetermined number of times. You can enjoy the thrill and expectations.

According to the embodiment of the present invention, when the random fluctuation lottery means performs the lottery, if the number of times determined in the previous lottery has not expired, the remaining number of times is Since it is added to the number of times determined by the lottery, winning the current lottery increases the number of times the high-probability state continues. In this case, it is highly possible that the player is playing the game without noticing that the number of times of continuation is increasing, and by knowing the reality later, the player can feel the benefit.

When the result of the lottery by the probability variation lottery means is displayed on the display means, the thrill and expectation that the player has can be further enhanced.

The control processing operation executed by the PU 75 will be described.

When the power is first turned on, a "CPU reset start-up process" is performed (step [hereinafter referred to as ST] 1). Next, the CPU 75 permits interruption (ST2). Here, by permitting the interrupt, an “interrupt process” shown in FIG. 4 described later is started.
Then, "error notification process" is performed (ST3), and "special symbol game control process" is performed (ST4). This "special symbol game control process" will be described later with reference to FIG.

Next, the "interrupt processing" shown in FIG. 4 will be described.

First, the CPU 75 saves each register (ST11) and updates various counters (S).
T12). Here, the CPU 75 updates the counter values of the jackpot determination random number counter 82, the probability variation lottery random number counter 83, the outlier symbol determination random number counter 84, the jackpot symbol determination random number counter 85, and the probability variation continuous lottery random number counter 86. . Big hit determination random number counter 82

The probability variation lottery random number counter 83 and the probability variation continuous lottery random number counter 86 are updated within the value range of “0” to “64”. The falling symbol determining random number counter 84 and the jackpot symbol determining random number counter 85 are updated within the range of the values of “0” to “11”.

Next, the CPU 75 performs "timer update processing" for performing timer update processing required for game processing such as a timer for managing animation display time (ST1).
3). Here, subsequently, the CPU 75 executes processing of various input signals from the sensors and switches (ST1.
4). In the processing of ST14, when there is an input signal from the gate switch 70, the CPU 75 issues a control command to execute the "ordinary symbol processing" described later, and the input signals from the respective winning ball sensors 71, 72, 73. If there is, a control command (payout request) for executing the “payout process” described later is output. When there is an input signal from the starting winning ball sensor 72, the CPU 75 outputs the above-mentioned payout request, and at the same time, the jackpot determination random number counter 82, the probability variation lottery random number counter 83, and the outlier symbol determination random number counter 84. , RAM78 the counter values of the jackpot symbol determination random number counter 85 and the probability variation continuous lottery random number counter 86
To store.

Next, the CPU 75 is an LE for normal symbol lottery.
A process (referred to as "normal symbol process") relating to display on D12a and 12b is executed (ST15). In this "ordinary symbol processing", the CPU 75, the normal symbol lottery LED1
2a, 12b flashing operation, LE for green ordinary symbol lottery
D12a performs a lottery whether it is stopped in a state where it is stopped or a red normal symbol lottery LED 12b is kept in a state of being illuminated, and based on the lottery result, the blinking operation of the normal symbol lottery LEDs 12a, 12b is controlled.

Next, the CPU 75 executes a "prize ball payout process" for paying out winning balls according to the payout request issued in the process of ST14 (ST16). Next, the CPU 75
"Error processing" for processing error signals generated from various devices is performed (ST17). Next, the CPU 75 performs "transmission data processing" to output transmission data such as a command generated in ST43 (FIG. 5) described later to the circuit corresponding to each data (ST18). continue,
Each register saved in ST11 is restored (S

Next, the "special symbol game control process" will be described with reference to FIG.

First, the CPU 75 stores the count value and the like of the big hit determination random number counter 82 in the RAM 78 based on whether or not there is a start winning, that is, based on the input from the starting winning ball sensor 72 in the input signal processing of ST14. It is determined whether or not it has been performed (ST31). This judgment is "N
When it is "O", "demo display processing" is performed (ST32).
Specifically, when a predetermined time has elapsed after the last game was finished, a "demo display command" is displayed on the liquid crystal control circuit 91.
Process for sending.

When the determination in ST31 is "YES", C
The PU 75 determines whether or not the “probability change flag” set in ST64 (FIG. 8) described later is set (ST33). If "YES" in this ST33, that is, if the "probability change flag" is set, the ROM
The "high probability table" is read from 77, the table is stored in the RAM 78 (ST34), and "N" is returned in ST33.
When it is "O", that is, when the "probability change flag" is not set, the "normal table" is read from the ROM 77 and stored in the RAM 78 (ST35). Here, the “high-probability table” and the “normal table” are tables referred to in a lottery (ST36 described later) for determining whether or not to generate a big jackpot, and the “high-probability table” has a high jackpot occurrence. The lottery probability is set so as to be determined by the probability. Therefore, the above "high probability state" is a gaming state in which the "probability change flag" is set and whether or not a big hit is generated is determined based on the "high probability table".

Then, in ST33 or ST34, the RAM 7
A lottery is performed to determine whether or not a big hit should be generated based on the table set to 8 (ST36).

Here, (1) of FIG. 6 shows an example of "high probability table", and (2) of FIG. 6 shows an example of "normal table". In the process of ST36, R in the process of ST14
The count value of the big hit determination random number counter 82 stored in the AM 78 is read as a random number value, and when the “high probability table” is set, the read random number values are “7”, “67”, “107”, Occurrence of "big hit" is determined when it is either "247" or "287", and when the "normal table" is set, when the read random number value is "7", "big hit" Occurrence is determined. As shown in FIG. 6, when the “high probability table” is set, that is, the jackpot occurrence rate in the high probability state is 5/335 (about 1.5%), and the “normal table” is set. When it is, that is, in the normal state, the jackpot occurrence rate is 1/335 (about 0.3%).

If "YES" in ST36, that is, if the "big hit" is determined to occur, then the CPU
75 determines the effect (variation pattern of the special symbol, predictive effect, reach effect, etc.) for the big hit displayed on the liquid crystal display device 4 (ST37), and then R in the processing of ST14.
Big hit symbol determination random number counter 8 stored in AM78
The count value of 5 is read out as a random number for determining the big hit symbol, and the "big hit symbol" is determined based on the "big hit symbol determination table" stored in the ROM 77 (ST3).
8). In the "big hit symbol determination table", a plurality of predetermined "big hit symbols" and random numbers corresponding to each of them are set, and the read random number values for big jack symbol determination are "big hit symbol determination table". By collating with the random number value set in, one "big hit symbol" is determined.

If "NO" in ST36, that is, if "disappearance" is determined, then the CPU 75 determines the effect for "disappearance" to be displayed on the liquid crystal display device 4 (ST39).

Next, the CPU 75 determines whether or not the reach effect is included in the effect for the loss determined in ST39 (ST40). If "YES" here, that is, the effect for the "off" is selected. When the reach effect is included, the left stop symbol determination random number counter 87, the middle stop symbol determination random number counter 88, and the right stop symbol determination random number counter 8 stored in the RAM 78 in the process of ST14.
The count value of 9 is read as a random number value for left stop symbol determination, a random number value for medium stop symbol determination and a random number value for right halt symbol determination, respectively, "left stop symbol determination table" in the ROM 77, "middle stop symbol" With reference to the "decision table" and the "right stop symbol determination table", the outlier symbol to be a reach (the special symbol on the left and right is the same and the special symbol in the left and right is different from the left and right is referred to as "leach with reach symbol"). It is decided (ST41).

In the processing of ST41, the CPU 75
First, the left stop symbol is determined with reference to the "left stop symbol determination table" based on the read random number for left symbol determination. Here, this ST41 is a process performed in the case of "with reach", so that the CPU 75 makes the right stop symbol the same as the left stop symbol. Then, the CPU 75
Based on the read random number value for symbol determination, refer to the "middle halt symbol determination table" to determine the medium halt symbol. Here, since this ST41 is a process performed in the case of "disengagement", if the selected middle stop symbol is the same as the left and right stop symbols, the symbol shifted by one frame is set as the middle stop symbol.

When ST40 is "NO", that is, when the reach effect is not included in the "off" effect,
Similar to ST41, the CPU 75 reads the random number value, refers to the "left stop symbol determination table", the "middle stop symbol determination table" and the "right stop symbol determination table" in the ROM 77, and refers to an outlier symbol that does not reach ( "Special design without reach" in a stop mode with different left and right special designs
Say. ) Is determined (ST42).

In this ST42, unlike the processing of ST41, the CPU 75 first sets the left stop symbol and the middle stop symbol based on the read random number value for left symbol determination and the random number value for medium symbol determination. Determined, then determine the right stop symbol based on the read random number for right stop symbol determination,
If the right stop symbol is the same as the left stop symbol, the symbol shifted by one frame is determined as the right stop symbol.

Next, the CPU 75 generates various commands designating the decided effect and stop symbol, and stores these commands in the RAM 78 (ST43). here,
The command stored in the RAM 78 is transmitted to the liquid crystal control circuit 91 and the voice control circuit 92 by the process of ST18 described above. Upon receiving the command, the liquid crystal control circuit 91 and the voice control circuit 92 execute a process based on the information designated in the received command, whereby the liquid crystal display device 4 displays a predetermined image (animation, characters) according to the command. Is displayed, and a predetermined sound corresponding to the command is output to the speaker 101.

Next, it is determined whether or not the determination result in ST36 is "big hit" (ST44). If "YES", the process proceeds to ST45, and if "NO", the process proceeds to ST46. In ST45, a "big hit game process" that executes a process relating to the special game state is performed, and after the "big hit game process" is finished, whether or not a high probability state is generated and the probability variation continuation number are determined by lottery. "Variable lottery process" is performed (ST49), and the "special symbol game control process" ends. The “big hit game process” will be described in the flowchart of FIG. 7, and the “probability variation lottery process” will be described in the flowchart of FIG.

In ST46, it is determined whether or not the "probability change flag" is set in the RAM 78, and if "NO", this "special symbol game control process" is terminated and "Y".
When ES ", that is, when the" probability variation flag "is set, a process of subtracting" 1 "from the" probability variation counter "is performed (ST47). "Probability change flag" is ST4
This is set when the "probability fluctuation lottery process" of 9 wins other than "no continuation". In addition, "probability change counter"
Is formed in a predetermined area of the RAM 78 as a counter for timing the execution of the "probability variation lottery process", and the probability variation continuation number determined in the "probability variation lottery process" is set as an initial count value in the counter. It
Therefore, when the count value is subtracted and becomes “0”, the “probability variation lottery process” is executed.

Next, it is judged whether or not the count value of the probability variation counter is "0" by the subtraction processing in ST47 (ST48), and if "NO", the "special symbol game control processing" is ended. , "YES", ST49
Then, the "probability variation lottery process" is performed, and then the "special symbol game control process" is ended.

As described above, when the variation result of the special symbol is "big hit" (when "YES" in ST44), "probability variation lottery process" is always performed after the end of the special game state, and the next variation. Is drawn as a high probability state or whether the high probability state is continued or not. On the other hand, when the variation result of the special symbol is “out” (when “NO” in ST44), it is during a high probability state (“YE” in ST46).
S ”)“ Probability variation lottery process ”only when the set number of continuous probabilities changes (when the probability counter number = 0)
Is performed, and whether or not to continue the high probability state is drawn.
That is, even if the “out” continues, the “probability variation lottery process” is not performed and the high-probability state is maintained until the set number of continuous probabilities changes.

FIG. 7 is a flow chart showing the procedure of the "big hit game process".

First, "big hit fanfare processing" is performed (ST51). In this big hit fanfare processing, the “big hit fanfare sound command” and the “big hit fanfare display command” are stored in the RAM 78. These commands stored in the RAM 78 are transmitted to the liquid crystal control circuit 91 and the voice control circuit 92 by the processing of ST18 described above.

Next, the CPU 75 performs a round display switching time check process (ST52). In this process, the time from when the special winning opening 8 is closed to when the special winning opening 8 is opened next is managed. Specifically, the "round switching timer" starts counting from the time when the special winning opening 8 is closed in the special winning opening opening / closing process (ST54) described later.

Next, special game state time check processing is carried out (ST53). In this processing, the time for maintaining the open state of the special winning opening 8 (for example, 30 seconds), the time for which the special winning opening 8 is set as a specific area, and the like are managed. Then, a special winning opening / closing process is performed (ST54). In this process, the special winning opening 8 is opened when the count value of the "round switching timer" in ST54 reaches a predetermined value. Also, ST54
In the process, the closing process of the special winning opening 8 is performed when the number of game balls winning the special winning opening 8 reaches a predetermined number, or based on the special game state time checking process of ST53.

Next, the CPU 75 executes "special game state display processing" (ST55). In this process, the big winning mouth 8
When is opened, "big hit V front sound command" and "big hit V front display command" are stored in the RAM 78, and when the game ball passes through the specific area of the special winning opening 8, "big hit V
RA for "rear sound command" and "big hit V rear display command"
When it is stored in M78 and the special winning opening 8 is closed, the "big hit interval sound command" and the "big hit interval display command" are stored in the RAM 78. These commands stored in the RAM 78 are transmitted to the liquid crystal control circuit 91 and the voice control circuit 92 by the processing of ST18 described above.

Next, the CPU 75 determines whether or not the special winning opening 8 is open (ST56), and this determination is "YE."
If "S", the process proceeds to ST52, and if "NO", the process proceeds to ST57. In the process of ST57, whether or not the game ball has passed through the specific area, and the special winning opening 8 is repeated a predetermined number of times. It is determined whether (for example, 16 times) the open state is set.
If this determination is "YES", the process proceeds to ST52, and if "NO", a special game state end process is performed (ST58). In this special game state end processing, C
The PU 75 stores the “big hit end sound command” and the “big hit end display command” in the RAM 78. RAM78
The commands stored in the above are transmitted to the liquid crystal control circuit 91 and the voice control circuit 92 by the processing of ST18 described above.

FIG. 8 is a flow chart showing the procedure of the "probability variation lottery process".

First, the CPU 75 reads out the count value of the random number for random probability selection 83 stored in the RAM 78 in the process of ST14 as a random value for random probability selection (ST61).

Next, the CPU 75 collates the random number values "0" to "63" read out in ST61 with the random number range of the "probability fluctuation lottery table" stored in the ROM 77, and determines that a high probability state has occurred. It is judged whether or not it is won (S
T62).

For example, FIG. 9 shows a "probability fluctuation lottery table".
In this example, when the random number value read out in ST61 is “32” to “63”, the winning is won, and the probability of continuous variation is 50
It is decided to be a time. As shown in FIG. 9, the probability that a high-probability state will occur in the normal state (in the high-probability state, the probability of continuing 50 more times after the 50th time which is the probability variation continuation number) is 1/2. is there.

FIG. 10 shows another example of the “probability fluctuation lottery table”. Here, the fact that the random number value read out in ST61 is “32” to “63” is a win, as in the table of FIG. Although the same, the probability variation continuation number is 50 when the random number value is "32" to "55", and the probability variation continuation number is 500 when the random number value is "56" to "63". In this case, the probability that a high probability state will occur in the normal state is 1/2, and the probability that a high probability state with a probability variation duration of 50 times will occur is 3/8 and a high probability state with a probability variation duration of 500 times. The probability of occurrence of is 1/8. In the high-probability state, the probability of continuing 50 more times is 3/8 in the relevant lottery when the defined number of continuous probability changes has expired (when the above-mentioned probability change counter becomes “0”). The probability of continuing 500 times is 1/8.

The number of continuous probability changes is not limited to 50 times or 500 times as shown in FIGS. 9 and 10. For example, it can be set to any number such as 10 times, 100 times, and 1000 times.

In the flowchart of FIG. 8 again, ST
If "NO" in the process of 62, that is, "no continuation" is determined, the CPU 75 executes the process of ST65, and if "YES" in the process of ST62, that is, other than "no continuation" (see FIG. 9). 50 times in the case of the “probability fluctuation lottery table” and 50 times or 500 times in the case of the “probability fluctuation lottery table” of FIG.
Sets the determined number of continuation of probability variation to the probability variation counter (ST63). Next, the CPU 75 sets the probability variation flag in a predetermined area of the RAM 78 (ST64) and ST6.
The process of 6 is executed. In ST65, the CPU 75 causes the R
The probability variation flag set in the predetermined area of AM78 is cleared, and the process of ST66 is executed.

In ST66, the CPU 75 stores a "probability change state command", which is a command command for displaying "probability change notification" on the liquid crystal display device 4, in a predetermined area of the RAM 78. This command is transmitted to the liquid crystal control circuit 91 by the processing of ST18 described above. "Probability change notification"
It informs information about probability fluctuations. Specifically,
The result of the lottery in ST62 is notified to the player by image information (including animation and characters). For example, in the normal state, the process of ST62 is “not continued”
If you win any other than the above, the words "High probability rush" will be displayed. Further, in the high-probability state, when a winning other than "no continuation" is won in the processing of ST62, the character "still continued" is displayed. In addition, when "No continuation" is determined in ST62 in the high probability state, "End"
Display the characters and.

Next, with reference to FIG. 11, a specific example of the “probability change notification” displayed on the screen of the liquid crystal display device 4 will be described taking the case where the high probability state continues 200 times as an example.

FIG. 11A shows the display contents of "probability change notification" when the probability variation lottery after the jackpot game is finished is won in the normal state where the probability variation flag is not set.
Here, the display content when the probability variation continuation number is determined to be "50 times" in the probability variation lottery is shown, and the text "High probability entry" is displayed on the screen.

FIG. 11 (2) shows that the high probability state is entered.
In the probability fluctuation lottery performed when the fluctuation display for the second time is finished, the display content of the "probability change notification" when the winning is won is shown. Here, the display content when the probability variation continuation number is determined to be “50 times” is shown, and the characters “Still continuing” are displayed on the screen.

In FIG. 11C, the high probability state is further 50 times.
In the probability fluctuation lottery that is performed when the 50th fluctuation display (100th time after first entering the high probability state) is completed, the display content of the "probability change notification" when winning Indicates. Here, the display contents when the probability variation continuation number is determined to be “50 times” are shown.
On the screen, the text “Still going on” is displayed.

In FIG. 11 (4), the high probability state is further 50
In the probability fluctuation lottery that is performed when the 50th fluctuation display (150th time after first entering the high probability state) is finished, the display content of "probability notification" when winning Indicates. Here, the display contents when the probability variation continuation number is determined to be “50 times” are shown.
On the screen, the text “Still going on” is displayed.

In FIG. 11 (5), the high probability state is further 50
In the probability fluctuation lottery performed when the 50th fluctuation display (the 200th time after entering the high-probability state first) is completed, "No continuation" is decided without winning. The display content of the "probability change notification" is shown. As the display content of the screen, the character "End" is displayed.

As described above, the "probability change notification" is issued when the probability variation lottery process that may end the continuation of the high probability state is completed, so that the player continues to be in the high probability state. You can enjoy the thrill and expectation of whether or not.

In the specific example of FIG. 11, the “probability change notification” by characters is shown. However, when the information about the probability change is notified by changing the pattern or the color, or the information about the probability change is displayed by the change of the display content of the animation. May be notified. Further, the probability change notification is not limited to the display on the liquid crystal display device 4. For example, a mechanical reel, a moving object such as a model (a so-called “character”), a speaker, a light emitting means, L
It may be performed using an ED dot matrix or the like.

Further, it is also possible to directly display the number of continuation of the probability variation determined as "probability notification". For example, in FIG.
When using a "probability fluctuation lottery table" such as
The probability variation continuation number is not limited to 50 times but may be 500 times in rare cases. Therefore, the “probability variation lottery table” in FIG.
Compared with the case of using, the “probability change notification” becomes clearer and the enjoyment of the game is enhanced.

While the high-probability state is continuing, characters or the like for notifying the player that the high-probability state is continuing are displayed on the screen. For example, on the screen, "High probability state"
Display the characters and.

The above is the case where the occurrence and continuation of the high probability state is drawn by lot when the probability variation continuation number of the high probability state ends, but as another example, the high probability state is counted when the predetermined number of times is counted. You may make it perform the lottery (probability change continuation lottery process mentioned later) as to whether or not to continue. As an example thereof, a case where a lottery is performed to determine whether or not to continue the high probability state when the probability variation continuation number reaches 50 will be described below. Here, even when the probability variation continuation number has not expired, a lottery is conducted to forcibly continue the high probability state when 50 games are counted as the continuation number. The number of times determined by the lottery is added to the number of continuations that have been made.

FIG. 12 illustrates another example of the "special symbol game control process". Here, the number of continuations is 5
The "special symbol game control process" in the case of performing a lottery as to whether or not to continue the high probability state when counting 0 games will be described.

First, the CPU 75 stores the count value and the like of the big hit determination random number counter 82 in the RAM 78 based on whether or not there is a start prize, that is, based on the input from the start prize ball sensor 72 in the input signal processing of ST14. It is determined whether or not it has been performed (ST71). This judgment is "N
When it is "O", "demo display processing" is performed (ST72).
Specifically, when a predetermined time has elapsed after the last game was finished, a "demo display command" is displayed on the liquid crystal control circuit 91.
Process for sending.

When the determination in ST71 is "YES", C
The PU 75 determines whether or not the "probability change flag" is set (ST73). "YES" in this ST73
When the “probability variation flag” is set, the “high probability table” is read from the ROM 77 and the table is stored in the RAM 78 (ST74), and ST
If "NO" in 73, that is, if the "probability change flag" is not set, the "normal table" is read from the ROM 77 and set in the RAM 78 (ST7).
5). Then, it is determined whether or not it is a big hit based on the table set in the RAM 78 in ST73 or ST74 (ST76).

If "YES" in ST76, that is, if "big hit" is determined, then the CPU 75
Determines a big hit effect to be displayed on the liquid crystal display device 4 (ST77), and subsequently determines a "big hit pattern" by the same processing as ST38 (ST78).

If "NO" in ST76, that is, if "disappearance" is determined, the CPU 75 subsequently determines the effect for "disappearance" to be displayed on the liquid crystal display device 4 (ST79).

Next, the CPU 75 determines whether or not the reach effect is determined in the effect for the loss determined in ST79 (ST80), and when the result is "YES", that is, the effect for the "miss" is selected. When the reach effect is included, the same process as ST41 is performed to determine the "reach missing pattern" (ST81).

[0108] If "NO" in ST80, that is, if the reach effect is not included in the effect for "off",
The same process as ST82 is performed to determine the "reach-off pattern" (ST82).

Next, the CPU 75 generates various commands designating the decided effect and stop symbol, and stores these commands in the RAM 78 (ST83).

Next, the CPU 75 determines whether the determination result in ST76 is "big hit" (ST84),
If "YES", the process proceeds to ST85, and if "NO", the process proceeds to ST87. In ST85, the above ST
"Big hit game processing" that performs the same processing as 45 is performed,
After the end of this "big hit game process", a "probability fluctuation lottery process" for performing the same process as ST49 is performed (ST8
6), the "special symbol game control process" ends.

At ST87, the CPU 75 causes the RAM 78 to
It is determined whether or not the "probability variation flag" is set, and when "NO", this "special symbol game control processing" is terminated, and when "YES", that is, the "probability variation flag" is set. When, "probability change counter"
Is subtracted from "1" (ST88), and subsequently, "1" is subtracted from a "probability change digestion counter" described later (ST89).
The "probability variation flag" is set when the winning is other than "no continuation" in the "probability variation lottery process" of ST86. The "probability variation number counter" is set with the probability variation continuation number determined in the "probability variation lottery process" as an initial count value.
Further, the “probability change digestion counter” is formed in a predetermined area of the RAM 78 as a counter for timing the execution of the “probability change continuous lottery process” in ST91 described later.
The "probability variation continuous lottery process" is set to be performed when a predetermined number of times have passed since the last probability variation continuous lottery process, and the predetermined number (here, 50 times) is set as an initial count value of the "probability variation digestion counter". It Therefore, when the count value is subtracted and becomes "0", the "probability variation continuous lottery process" in ST91 is executed.

After subtracting "1" from the "probability variation digestion counter" in ST89, the CPU 75 determines whether or not the counter has become "0" (ST90), and when "YES" here, that is, the counter is When it becomes “0”, the “probability variation continuous lottery process” is executed (ST9
1) When the determination in ST90 is "NO", the "special symbol game control process" is ended.

FIG. 13 is a flowchart showing the procedure of the "probability continuation lottery process" executed in ST91.

First, the CPU 75 reads the count value of the probability variation continuous lottery random number counter 86 stored in the RAM 78 in the process of ST14 as the random number for the probability variation continuous lottery (ST101).

Next, the CPU 75 collates the random number values "0" to "63" read out in ST101 with the random number range of the "probability variation continuous lottery table" stored in the ROM 77, and determines whether or not it is a win ( ST102).

FIG. 14 shows an example of the "probability variation continuous lottery table" referred to in the above probability variation continuous lottery processing.
When the random number value read out in ST101 is "32" to "63", the winning is won, and when the random number value is "32" to "54", the number of continuous probability variation is 50 times and the random number value is "55" to "61". When the random number value is "62" to "63", the probability variation continuation number is distinguished from 500 times. In this case, the probability that the high-probability state will continue is 1/2, and the number of continuations is 5
The probability of being determined to be 0 times is 24/64, the probability of being determined to be 100 times is 7/64, and the probability of being determined to be 500 times is 1/64. The number of continuation of probability variation is not limited to 50 times, 100 times, or 500 times, and can be set to any number.

In the flowchart of FIG. 13 again, S
When "NO" in the process of T102, that is, when "no continuation" is determined, the CPU 75 executes the process of ST105, and when "YES" in the process of ST102, that is, when the probability variation continuous lottery process is won. (The number of continuations is 5
When it is determined to be 0 times, 100 times, or 500 times), the CPU 75 adds the determined number of continuations to the probability variation counter (ST103). That is, when the probability variation continuous lottery process is executed before the count value set in the probability variation counter becomes "0", the count value remaining in the probability variation counter (referred to as "remaining number"). Is added to the number of continuations determined in ST102.

Next, the CPU 75 sets "50" in the probability variation digestion counter (ST104) and executes the processing of ST107.

In ST105, the CPU 75 determines whether or not the count value of the probability variation counter is "0", and "N"
If "O", move to ST104, and if "YES", R
The probability change flag set in AM78 is cleared (ST106).

In ST107, the CPU 75 stores the "probability change state command" which is a command command for displaying the "probability change notification" on the liquid crystal display device 4 in a predetermined area of the RAM 78. This command is transmitted to the liquid crystal control circuit 91 by the processing of ST18 described above.

In the above embodiment, when the number of continuations of the high-probability state has expired, a lottery as to whether or not to continue the high-probability state is not conducted, but a predetermined number of times (here, 50 times) is performed. When the time has expired (when the probability variation digestion counter = 0), a “probability variation continuous lottery process” is performed, and a lottery is performed as to whether or not to continue the high probability state. Therefore, even if all the probability variation continuation counts are left undigested,
A lottery is conducted as to whether or not the high-probability state is to be continued at the time of zero digestion. Then, if the player does not win the lottery, the normal state is entered, and if the player wins, the number of times corresponding to the winning is added to the remaining number of times to maintain the high probability state.

FIG. 15 shows a specific example of the “probability change notification” displayed on the screen of the liquid crystal display device 4 in the case of processing by the procedure described with reference to FIGS. 12 and 13. here,
The case where the high probability state continues 200 times will be described as an example.

FIG. 15 (1) shows the display contents of "probability change notification" when the probability variation lottery after the jackpot game is finished is won in the normal state in which the probability variation flag is not set.

Here, the case where "no continuation" is determined without winning in the probability variation continuous lottery is shown. However, since the remaining number of times is 50, the character "I'm still continuing" is displayed as the content displayed on the screen.

In FIG. 15 (5), the high probability state is further 50
The display content of the "probability change notification" after the probability variation continuous lottery performed when the 50th (200th time after first entering the high probability state) variation display is ended when the continuation is continued. Here, the case where "no continuation" is determined without winning in the probability variation continuous lottery is shown. In this case, since the remaining number of times is “0”, the content displayed on the screen is
The message “End” is displayed.

In the above embodiment, the lottery is carried out as to whether or not the high probability state is to be continued when the probability variation continuation count is exhausted 50 times, but the present invention is not limited to this. For example, the number of digestion of the probability variation continuation number performing the lottery is 10 times, 100 times,
It can be set to any number such as 500 times.
