Abstract

PROBLEM TO BE SOLVED: To vary the probability of leading out a judgment pattern concerning probability variation. SOLUTION: When a game ball enters a variable winning device 22 (S31: Yes), a jackpot random number is extracted (S32), and a probability variation judgment random number is extracted (S33). A judgment is made on a jackpot by the a jackpot random number (S34), when the judgment is for a jackpot (S34: Yes), a jackpot pattern is determined in a stationary pattern extraction (S35). The extraction rate of a jackpot pattern is set for each probability variation random number, and the probability of probability variation being judged as a jackpot is 27% for 000, the probability of probability variation (probability variation probability) is 50% for 111, and the probability of probability variation is 88% for 333. Namely, the probability of probability variation differs depending on a jackpot pattern, and accordingly, the probability of leading out a judgment pattern showing that probability variation is judged as a success is different.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of ball and ball game machines.

[0002]

2. Description of the Related Art Special symbol judging means for judging a hit or miss when a game ball enters a starting area, special symbol displaying means for displaying the judgment result by the special symbol judging means in a special symbol, A special game execution means for executing a special game advantageous to the player on condition that the judgment by the symbol judgment means is a hit, and a probability of winning by the judgment by the special symbol judgment means after the end of the special game There is a ball game machine including a determination symbol display means for displaying a determination symbol indicating whether or not set to a high probability,
It is called a probability variation machine because it changes the probability of winning in the determination by the special symbol determination means.

[0003] In the conventional probability variation machine, the probability of winning in the determination by the special symbol determination means (hereinafter, "determination probability")
Whether or not is set to a high probability after the end of the special game (probability fluctuates) is displayed using a special symbol for displaying the determination result or using a dedicated determination symbol.

[0004]

When a special symbol is used for displaying the presence or absence of a probability change, usually about half of the special symbols are regarded as a probability variation symbol for indicating the probability variation, and the type of the probability variation symbol is It did not change.

That is, at the same time when the probability change symbol is confirmed and displayed, it is found that the probability is always changed after the end of the special game, and it is possible to give the player an expectation of being excited or excited about whether or not the probability is changed. could not. Conversely, even when a special symbol other than the probable symbol is confirmed and displayed, it is determined that the probability does not fluctuate after the end of the special game, and the player has an expectation of being excited or excited about whether or not the probability fluctuates. I couldn't make it. Also, in this case, there was no fun after the end of the special game, and the interest was impaired.

On the other hand, when displaying the presence / absence of the probability change in the judgment symbol, the presence / absence of the probability change cannot be known unless the display of the judgment symbol is confirmed. However, actually, when a specific special symbol (for example, 333 or 777) is confirmed and displayed, the probability is almost certainly changed, so that, similarly to the case of using the above-described probability variable symbol,
I wasn't able to get excited or excited.

[0007]

According to the first aspect of the present invention, there is provided a ball game machine for determining a hit or a miss when a game ball enters a starting area. Determination means, a special symbol display means for displaying the determination result by the special symbol determination means in a special symbol,
A special game execution means for executing a special game advantageous to a player on the condition that the judgment by the special symbol judgment means is a hit, and a probability of winning by the judgment by the special symbol judgment means of the special game. In a ball game machine having a judgment symbol display means for displaying a judgment symbol indicating whether or not to be set to a high probability after the end, a random number value extracted as an opportunity that a game ball has entered the starting area The derivation probability of the determination symbol is changed based on the determination symbol.

The result of the judgment by the special symbol judging means is displayed as a special symbol, and whether or not the probability of winning in the judgment by the special symbol judging means is set to a high probability after the end of the special game (whether or not the probability fluctuates) ) Is displayed as a judgment symbol, so that the presence or absence of a probability change cannot be determined simply by confirming and displaying the special symbol.

For this reason, the timing at which the determination symbol is determined and displayed is set between the display of the special symbol and the end of the special game, for example, at the start interval of the special game (for example, before the opening of the first special winning opening). Intervals between rounds (the period from the closing of the winning opening to the next opening),
By setting the special game end interval (the period from the closing of the last big winning opening to the return to the normal game state), etc., the special symbol fixed and displayed prior to the special game, Until the final display, a sense of expectation of the probability fluctuation can be given.

[0010] Further, since the derivation probability of the judgment symbol is changed based on the random number value extracted when the game ball enters the starting area, the probability (probable inrush rate) of whether or not the probability is changed is determined, for example. It can be changed each time. Conventionally, the ratio of probable change symbols in special symbols is constant, and the ratio of symbols that show probability fluctuations in judgment symbols is also constant, so the probability of inrush rate is constant,
With the configuration according to the present invention, the probability-change inrush rate can be changed, and interest is enhanced.

According to a second aspect of the present invention, in the ball game machine according to the first aspect, based on at least two random numbers extracted when the game ball enters the starting area. It is characterized in that the derivation probability of the judgment symbol is changed. Varying the derivation probability of the determination symbol with two random numbers is more varied than changing it with one random value.

According to a third aspect of the present invention, there is provided a bullet game machine, wherein a special symbol judging means for judging a hit or miss when the game ball enters the starting area, and a judgment result by the special symbol judging means is displayed in a special symbol. Special symbol display means, a special game execution means for executing a special game advantageous to the player as an essential condition that the judgment by the special symbol judgment means is a hit, and a hit by the judgment by the special symbol judgment means. Is determined by the special symbol determination means, the determination symbol display means displaying a determination symbol indicating whether or not the probability is set to a high probability after the end of the special game. The derivation probability of the determination symbol is changed depending on the type of the special symbol displayed at the time.

[0013] Since the derivation probability of the judgment symbol is changed according to the type of the special symbol displayed when the judgment by the special symbol judgment means is a hit, it is possible to change the probable change inrush rate as in the first aspect. Interesting. Special symbols (big hit symbols) displayed when the determination by the special symbol determination means is a hit are 000, 111, 2
22,333,444,555,666,777,88
Assuming that there are 10 types of 8,999, 333 or 77
When the special symbol No. 7 is fixedly displayed, the judgment symbol which fluctuates in probability is extracted with a probability of 85%, and 111, 555 and 99 are extracted.
When the 9 special symbols are confirmed and displayed, the determination symbols which change in probability are extracted with a probability of 60%, and 000, 222, 44.
When the special symbols of 4,666 and 888 are fixedly displayed, the determination symbols which change in probability are extracted with a probability of 30%, so that the probability of intrusion is set to 50% as a whole and the probability of intrusion is changed according to the special symbols. The rate can be varied. Of course, this is only an example, and the setting of the probable inrush rate corresponding to the special symbol is not limited to this.

According to a fourth aspect of the present invention, there is provided a bullet game machine, wherein a special symbol judging means for judging a hit or miss when the game ball enters the starting area, and a judgment result by the special symbol judging means is displayed in a special symbol. Special symbol display means, a special game execution means for executing a special game advantageous to the player as an essential condition that the judgment by the special symbol judgment means is a hit, and a hit by the judgment by the special symbol judgment means. And a determination symbol display means for displaying a determination symbol indicating whether or not the probability that the special game will be set to a high probability after the end of the special game. From the variation pattern that is a pattern of change until the special symbol is finally displayed, or the variation time from the start of the symbol variation until the special symbol is finally displayed, And wherein the changing the derived probability of serial determination symbol.

[0015] A change pattern which is a change pattern from the start of the change of the symbol by the special symbol display means to the final display of the special symbol, or the fluctuation time from the start of the fluctuation of the symbol to the final display of the special symbol, Since the derivation probability of the judgment symbol is changed, for example, when the jackpot is relatively simple and the variation time is short and the hit time is short, it is generally considered difficult to display the jackpot symbol. It is possible to set such that when the fluctuation time is long and the jackpot is reached, the derivation probability of the determination symbol that fluctuates in probability is reduced. The reverse setting is also possible.

Further, the following configuration can be added to the configuration according to any one of claims 1 to 4. (1) The display mode of the reach, for example, the background image at the time of the reach is changed according to the result of extracting the judgment symbol (that is, whether or not the probability varies). (2) The light emission mode of the lamp being reached is changed according to the result of extracting the judgment symbols. (3) The output mode of the sound effect (BGM) during the reach is changed according to the result of extracting the judgment symbols. (4) A display mode during a special game, for example, a display mode of an image in a start interval, an end interval, or an interval between rounds is changed according to a result of extracting a determination symbol.

By adding the configurations (1) to (4), the type of the judgment symbol (whether or not there is a probability change) can be announced or implied to the player.

[0018]

Next, an embodiment of the present invention will be described with reference to an embodiment of the present invention.

The prize ball control board 32 operates a ball cutting motor in accordance with a command sent from the main control board 30 to pay out prize balls, and exchanges data with a prepaid card unit (so-called CR unit). Then, in response to the lending request input from the CR settlement display board, the ball cutting motor is operated to pay out the lending ball, and the balance display on the CR settlement display board is controlled.

The firing control board 34 includes a command (reflecting a touch SW signal and a game situation) sent from the main control board 30, a firing handle rotation signal, and a fire stop switch (fire stop SW). The launching motor is controlled based on the signal to launch and stop the game ball, and the lighting of the touch lamp is controlled.

The sound control board 36 generates a sound signal in response to a command sent from the main control board 30, and drives a speaker with the sound signal to output sound. The lamp control board 38 controls the display of the general-purpose LED 17 in accordance with a command sent from the main control board 30, and also controls the turning on and off of various other LEDs and various lamps.

The image control board 40 constitutes the symbol display device 15 together with the LCD panel unit 16 and the accessory unit. The above-mentioned LCD panel 16a is a part of the LCD panel unit 16. The image control board 40 controls the display on the LCD panel unit 16, that is, the LCD panel 16 a, according to the command sent from the main control board 30. The symbol display device 15 (especially the LCD panel unit 16) corresponds to special symbol display means and judgment symbol display means. The image control board 40 serves as control means for these two means.

Next, the operation of the pachinko machine will be described. First,
The outline of the determination of the ordinary symbols related to the opening and closing of the variable winning device 22 will be described. The main control board 30 extracts one random number value (normal symbol lottery random number) from the random symbol counter for ordinary symbol determination when it is detected by the ordinary symbol operation SW that the game ball has passed through the gate 21. At this time, a well-known ordinary symbol hold storage process and a display of the number of ordinary symbol hold storage are performed, but the description thereof will be omitted.

The main control board 30 usually has a symbol random number
If it matches any of the pre-set normal symbol hit values, it is determined that it is a normal symbol hit; The main control board 30 generates a normal symbol display command for displaying the result of the determination, and
Is transmitted to the lamp control board 38,
The normal symbol is displayed in a variable manner, and after the time specified by the fluctuation time data included in the command, the normal symbol is fixedly displayed.

In the case of a normal pattern hit, the main control board 3
In the case of 0, a variable winning device control process for controlling opening and closing of the variable winning device 22 is performed after the normal symbol is fixed. As described above, the opening time of the variable winning device 22 is about 0.3 second in the normal probability mode and about 2.6 seconds in the high probability mode. In the case of a normal symbol loss, the variable winning device 22 is not opened.

When the variable winning device 22 is won, a special symbol determination (so-called big hit determination) is performed in a detection processing routine shown in FIG. As shown in FIG.
When the winning in the variable winning device 22 is detected by the first-type starting opening SW (S31: YES), one random value (big hit random number) is extracted from the random number counter for special symbol determination (S32). ), And extracts one random value (probability change determination random number) from the probability change determination counter (S33). For the jackpot random number, a well-known special symbol holding storage process and a display of the number of special symbol holdings are performed, but the description thereof will be omitted.

Next, the main control board 30 checks the jackpot random number against a preset hit value to determine whether or not the jackpot is a big hit (S34). In the case of the present embodiment, the number of hit values is small and the probability of determining a large hit is low (1/300 in this example). The normal probability mode is high, and the high probability mode is 1/60 in this example. The determination in S34 is made in any of these. The initial setting at the time of starting the pachinko machine is the normal probability mode. Thereafter, the mode is determined in a stop symbol extraction process described below, and the mode is switched at the end of a special game described later.

If the determination is a jackpot (S34: YE
S), a jackpot symbol is determined in the stop symbol extraction process (S35). In the case of the present embodiment, the big hit symbol is determined using the probability change determination counter (probability change determination random number) and the big hit symbol correspondence table shown in FIG. In the case of the present embodiment, the special symbol (big hit symbol and out-of-touch symbol) indicating the result of the jackpot determination is a form in which any one of three numerical symbols from 0 to 9 and alphabet symbols from A to F is arranged. Digit alignment (000, 111, 222, 333, 444,
555, 666, 777, 888, 999, AAA, B
BB, CCC, DDD, EEE, FFF) are jackpot symbols, and all other symbols are missing symbols. In the correspondence table of FIG. 6, 0 to 9 and A to F are shown as the big hit symbols, but these represent three digits (000, AAA, etc.) by one character.

The count range of the probability change determination counter is 0-9.
, And are updated in ascending order about every 2 ms.
The probability variation determination random number extracted from the probability variation determination counter is 1,
If it is one of 3, 5, 7, and 9, the probability variation determination is a hit and the high probability mode is determined. Otherwise, the normal probability mode is determined (outside the probability variation determination). In addition, the type of the determination symbol is also determined according to whether the probability variation is determined or not.

The details are as shown in FIG. 6, but the extraction rate of the jackpot symbol is set for each probability change judgment random number.
For example, for the probability change judgment random number 0, the jackpot symbol 000,
222, 444, 666, 888, AAA, CCC, E
EE is 10% each, and other jackpot symbols are 3 each
% Extraction rate is set, and a jackpot symbol 000, 222, 444, 666, 888, A
AA, CCC, EEE 1% each, 3 big hits
An extraction rate of 33% is set for 33 and 777, and an extraction rate of 3% is set for each of the other big hit symbols. In the case of the present embodiment, a jackpot symbol extraction counter (repeatedly counts from 0 to 99 in ascending order) is used. For example, if the value of the jackpot symbol extraction counter is 0 to 9 for the probability change determination random number 0, the jackpot symbol 000 is If it is 10-12, it will be a big hit 11
1 is extracted. Of course, this extraction method is an example and is not limited to this.

The probability that the probability variation judgment is a hit is 50% as a whole. However, for example, with respect to the big hit symbol 000, the probability fluctuation judgment is hit (the probability change judgment random number is 1,
3, 5, 7, 9) (probability of change) is 27%, and the probability of change for jackpot symbol 111 is 50%.
% And the jackpot symbol 333 have different probability of change of 88%, and the jackpot symbols 333 and 777 are different.
Has a high probability of change (88%),
55,999, BBB, DDD, FFF are moderate (50
%), And others (27%) are set low. In other words, the probability of change varies according to the jackpot design,
Correspondingly, the derivation probabilities of the judgment symbols indicating that the probability fluctuation judgment is a hit are different.

Subsequent to the stop symbol extraction process (S35), a variation pattern is extracted (S36). In the case of the present embodiment, the display of the special symbol is performed by scrolling the left symbol, the middle symbol, and the right symbol on the LCD panel 16a from top to bottom, and normally stopping in the order of the left symbol, the right symbol, and the middle symbol. Finally, the special symbol is finally displayed. Then, the time from the start of the scroll fluctuation to the temporary stop of the left symbol, the right symbol, and the middle symbol (for example, a state in which the left symbol and the right symbol move slightly), and whether or not the left symbol and the right symbol reach when temporarily stopped. Or the type of reach action in case of reach,
The presence / absence of re-variation after the three symbols are temporarily stopped, the type of each session at the time of re-variation, the time until the final three symbols are finalized (special symbol finalization), the special symbol to finalize Since the fluctuation pattern is specified using the parameters as parameters, the process of S36 is a process of determining each parameter.

In the present embodiment, there are a plurality of types of background images in the reach action, and the background images are changed according to the result of the probability variation determination (for example, A indicating that the probability variation determination has a high possibility of winning). (A background, a B background indicating that the possibility is low, and a C background indicating that it cannot be said), parameters for specifying such a background image are also determined.

If the jackpot determination is incorrect (S34: N
O) In the stop symbol extraction process (S37), a missing symbol is determined. This processing is different from the processing of S35 described above, and corresponds to the value of a counter for extracting a symbol which is updated every 2 ms, for example, and the symbol (a numerical symbol of 0 to 9 or an alphabetic symbol of A to F) This is a process of extracting the above (the one that does not become the big hit symbol) by three combinations. Then, similarly to S36, each parameter of the variation pattern is determined (S38).

After S36 or S38, a special symbol command including the parameters determined in these processes is generated and transmitted to the image control board 40 (S39). In addition,
The main control board 30 stores and holds the parameters determined in S36 or S38 in a range required for the subsequent processing.

If the jackpot determination is a hit,
At an appropriate position in this detection processing routine, the jackpot flag F
A process of setting 1 is performed, and in the case of a big hit and a probability variation determination being a hit, a process of similarly setting the probability change flag F2 to 1 is performed. (Modification of Detection Processing) In the above example, one random value (probability change determination random number) is extracted from the probability change determination counter (S3).
3) A probability change determination random number corresponding to the jackpot random number extracted in S32 may be extracted. One example will be described with reference to FIG. The routine shown in FIG. 4 is the same as the detection processing routine of FIG.

In the case of the modified example, the random number counter for special symbol determination is configured to repeatedly count, for example, integer values from 0 to 2999 in ascending order.
99, 899, 1199, 1499, 1799, 209
9, 2399 and 2699 are set. And
As for the value corresponding to the above-mentioned hit value in the numerical values of 0 to 2999 of the random number counter for special symbol determination, a probability change determination random number is linked as shown in FIG.

If the jackpot random number extracted in S32 is one of the ten types shown in FIG. 5, the probability change random number corresponding to each jackpot random number is extracted. The extracted random variation determination random number is used for the probability variation determination and the determination of the big hit symbol in FIG. 6 in the same manner as the detection processing routine in FIG.

Next, the display of special symbols on the LCD panel 16a will be described. When the image control board 40 receives the special symbol command from the main control board 30, the image control board 40 controls the LCD panel unit 16 to cause the LCD panel 16a to perform a variable display, and then to display the special symbol definitely. The outline of the control is as shown in FIG.

In this process, the image control board 40 first determines whether or not it has acquired the special symbol command from the main control board 30 (whether or not it has stored the special symbol command received in the communication process whose illustration and description are omitted). Or (S)
201), if the special symbol command has not been acquired, the present process ends. Since the acquired special symbol command is deleted when the execution of the process corresponding to the command is completed, the processed special symbol command is not stored. Further, commands other than the special symbol commands are also transmitted from the main control board 30, but the description of the processing corresponding to them is omitted.

When the special symbol command has been acquired (S201: Yes), the LCD panel unit 16 is controlled to start the variable display of the symbol on the LCD panel 16a (S202). In the case of the present embodiment, as illustrated in FIG. 8A, numeral symbols and alphabet symbols are scrolled, that is, displayed as a left symbol, a middle symbol, and a right symbol from top to bottom. In addition, "left design" described in FIG.
The characters “middle design” and “right design” are for clarity of explanation, and these characters are not actually displayed.

Next, the left symbol is temporarily stopped at the timing designated by the special symbol command (S203), and similarly, the right symbol is temporarily stopped (S204). Here, the temporary stop is a state in which the fluctuation of the symbol is not completely stopped,
For example, it is in a state of finely moving vertically or horizontally.

Here, since the two symbols are temporarily stopped, the hit display is determined depending on the last symbol (here, the middle symbol) if the two symbols are aligned (see FIG. 8B). And if it is reach (S205: YES),
The reach action display process (S206) is executed. Since the content of the reach action itself has little relevance to the present invention, the description is omitted. However, the background image is A background,
The background B and the background C indicate the level of the probability that the probability fluctuation determination has hit (probability fluctuates), so that the player can recognize the possibility of the probability fluctuation based on the background image.

The main control board 30 is provided for the LCD panel 1.
The command corresponding to the background A, background B or background C is transmitted to the sound control board 36 and the lamp control board 38 substantially in synchronization with the display of the reach action in 6a. Upon receiving this command, the sound control board 36
The GM signal is generated and sound is output from the speaker, and the lamp control board 38 changes the light emission mode of the lamp, such as blinking a specific lamp. Therefore,
The player can recognize the possibility of the probability variation based on the BGM or the light emission mode of the lamp.

It should be noted that the notification operation corresponding to the possibility of the probability change need not be performed for all of the change of the background image, the change of the BGM, and the change of the light emission mode of the lamp. But that goal can be achieved. Thereafter, when the temporary stop timing of the middle symbol specified by the special symbol command comes, the middle symbol is temporarily stopped (S209).
If the reach display has not been performed (S205:
NO), the middle symbol is temporarily stopped without executing the reach action display (S206) (S209).

Next, it is determined whether or not there is a re-change based on the special symbol command (S210).
0: YES), the three temporarily stopped symbols are scrolled all at once, and the re-change action specified by the special symbol command is displayed (S211). Confirm display (S
212). If there is no change again (S210: NO),
The three temporarily stopped symbols are fixed and stopped as they are (S212).

If the special symbol confirmed and displayed here is a big hit symbol, the special game is started subsequently. However, it is possible to adopt a configuration in which a judgment symbol is displayed before the start of the special game. . For example, when the big hit symbol (444 in the illustrated example) is definitely displayed as shown in FIG. 10A, the image control board 40 displays the LCD panel 16a on the LCD panel 16a.
In (b), a determination symbol composed of the character "one more time" and the character "only this time" is displayed. For example, by switching the color and brightness around the determination symbol, they are alternately selected. FIG. 10B shows a state where “one more time” is selected. After this alternate selection is continued for an appropriate time or number of times, one of them is kept in a selected state to indicate that this is selected (effective display).
In the case of the present embodiment, when the "one more" determination symbol becomes an effective display, it is notified that the high probability mode is set (probability variation) after the end of the special game, and the "only this time" determination symbol is effectively displayed. Then, it is notified that the normal probability mode is set after the end of the special game.

When the "one more time" determination symbol is continuously selected, an image that clearly indicates that the probability changes, as illustrated in FIG. 10C, is displayed. In this way, the presence or absence of the probability change can be notified to the player. When the determination symbol is displayed in this manner, the above-described special symbol command may include a parameter relating to the display of the determination symbol, or for example, from the main control board 30 in accordance with the timing at which the special symbol is confirmed and displayed. A command for instructing the display of the determination symbol may be transmitted to the image control board 40 to perform the above-described display operation.

The special game executed in this embodiment is the same as that of a known pachinko machine of the type called the first type, but the judgment symbol is displayed as a part of the display accompanying the special game. The special game will be explained including such examples. As shown in FIG. 9, in the special game routine, the main control board 30 sets the jackpot flag F1 to 1
Is determined (S301). If the determination is negative, no substantial processing is performed (the special game is not executed). Needless to say, the jackpot flag F1 is set to 1 until the jackpot symbol is finally displayed (or until the display of the judgment symbol is completed after the final display of the jackpot symbol is completed). Is returned without executing S302 and subsequent steps.

If the determination in S301 is affirmative, it is determined whether or not the special game execution flag F3 is set to 1 (S302). If the special game execution flag F3 is not set, this is set to 1 (S303),
A start interval process is executed (S304). In the start interval processing, the sound control board 36 is instructed to output BGM for the start interval, and the lamp control board 38
Instructs a jackpot lamp control to the image control board 4
To 0, an instruction to display an image for the start interval is given. In response to these instructions, the sound control board 36 outputs the jackpot fanfare from the speaker, and the lamp control board 38
Controls lighting of various decorative lamps and the like in a jackpot mode. The image control board 40 is provided on the LCD panel 16a as shown in FIG.
A jackpot fanfare screen illustrated in (a) is displayed.

A configuration in which a judgment symbol is displayed as a part of the display in the start interval can be adopted, and will be described here. For example, after the jackpot fanfare screen is displayed as shown in FIG. 11A, the image control board 40 includes the characters "one more time" and the characters "only this time" in FIG. 11B on the LCD panel 16a. The judgment symbol is displayed, and for example, by switching the color and brightness around the judgment symbol, they are alternately selected. FIG.
(B) shows a state where “one more time” is selected. After continuing this alternate selection for an appropriate time or number of times,
One of them is continuously selected to indicate that this is selected (a valid display). In the case of the present embodiment, when the "one more" determination symbol becomes an effective display, it is notified that the high probability mode is set (probability variation) after the end of the special game, and the "only this time" determination symbol is effectively displayed. Then, it is notified that the normal probability mode is set after the end of the special game.

When the "one more time" judgment symbol is continuously selected, "one time" illustrated in FIG.
An image that clearly indicates that the probability is fluctuated is displayed with characters such as “more change”. In this way,
The presence / absence of a probability change can be reported to the player. When the determination symbol is displayed in this manner, the command for instructing the display of the jackpot fanfare screen may include a parameter relating to the display of the determination symbol. The control board 30 may transmit a command for instructing the display of the determination symbol to the image control board 40 to perform the above-described display operation.

The main control board 30 opens the special winning opening 25 following the processing relating to the start interval (S304) (S307). When the special game execution flag F3 is set to 1 (S302: YES),
It is determined whether or not the special winning opening 25 is being opened (S305).

If the special winning opening 25 is not open, the display of the interval image between rounds is instructed to the image control board 40 to be displayed (S306), and after the interval time has elapsed, the special winning opening 25 is opened (S306). S307). If the special winning opening 25 is being opened (S305: YES), the image control board 40 is instructed to display a demo image corresponding to the number of times of opening (the number of rounds) (S308). As a result, FIG.
As illustrated in (a), characters indicating the number of rounds, images of stories that progress in each round, and the like are displayed on the LCD panel 16a. Further, the main control board 30 instructs the image control board 40 to display a count number indicating the number of winning balls to the special winning opening 25, a display indicating that the winning balls have passed through the specific area, and to display them on the LCD panel 16a.

Then, it is determined whether or not the special winning opening 25 is to be closed (S309). If it is determined that the special winning opening 25 is to be closed, the special winning opening 25 is closed (S310). In the case of this embodiment,
When about 30 seconds have passed since the opening of the special winning opening 25 or when ten winnings are detected in the special winning opening 25, the special winning opening 25 is set to be closed.

When the special winning opening 25 is closed, it is determined whether the special game is completed or continued (S311). In the case of the present embodiment, when the number of open times (the number of rounds) of the special winning opening 25 reaches the specified number, or when the game ball that has won the special winning opening 25 does not pass through the specific area, the special game ends. is there.

It is not rare that a game ball that has won the special winning opening 25 does not pass through a specific area, but it is extremely rare. Therefore, normally, the number of times the special winning opening 25 is opened reaches the specified number (16 rounds in this example), and the special game is ended. As described above, when displaying an image of a story that progresses in each round, this image can be used for displaying a determination symbol. FIG. 12 shows an example. In this example, a story is displayed with “Momotaro” as the theme, and the departure scene of Momotaro (FIG. 12 (a)) is displayed as a first round demonstration image, and a midway round is used for the Onigashima expedition scene and the Onigashima. The battle scene of the game is displayed (Fig. 12
(B)) Informing the player that if Momotaro beats the demon in the final 16th round, the character "one more change" is displayed and the probability varies. In this example, the character of "onemore change" or the background symbol which defeated the demon corresponds to the judgment symbol.

If it is determined in S311 that the special game has ended,
The big hit flag F1 is reset (S312), and the process related to the end interval (S313) is executed. In the end interval processing, the sound control board 36 is instructed to output BGM for the end interval.
8 instructs the end of the lamp control in the jackpot mode, and instructs the image control board 40 to display an image for the end interval. In response to such an instruction, the sound control board 36 outputs the BGM of the big hit end from the speaker, and the lamp control board 38 stops lighting control of various decorative lamps and the like in the big hit mode. The image control board 40 causes the LCD panel 16a to display an end interval screen.

Since a configuration in which a judgment symbol is displayed as a part of the display in the end interval can be adopted, a description will be given with reference to FIG. Starting from the jackpot fanfare screen (FIG. 13 (a)) and ending the final 16 rounds (FIG. 13 (b)) and reaching the end interval, for example, as shown in FIG.
A value of 0 causes the LCD panel 16a to display a judgment symbol composed of the characters "one more time" and the character "only this time". For example, by switching the color and luminance around the judgment symbol, they are alternately selected. . FIG. 13C shows a state where “one more time” is selected. After this alternate selection is continued for an appropriate time or number of times, one of them is kept in a selected state to indicate that this is selected (effective display). In the case of the present embodiment, when the "one more" determination symbol becomes an effective display, notification of a probability change after the end of the special game is given, and when the "only this time" determination symbol becomes an effective display, the normal probability is obtained after the end of the special game. Notification that the mode is set. If the “one more time” determination symbol is continuously selected, the above “one more”
It is better to clearly indicate that the probability changes with characters such as "chance" and "determination of probability change". Even in this case, it is possible to notify the player of the presence / absence of the probability change.

In the case of displaying the judgment symbol as in this example, the command for instructing the display of the end interval screen may include a parameter relating to the display of the judgment symbol. For example, the timing at which the end interval screen is displayed From the main control board 30 to the image control board 40
, A command instructing the display of the determination symbol may be transmitted to perform the above-described display operation.

Processing related to end interval (S31)
Subsequent to 3), it is determined whether or not the probability variable flag F2 is set to 1 (S314). If the determination is affirmative, the high probability mode is set and the probability variable flag F2 is reset (S31).
5) If negative, set to normal probability mode (S31)
6).

In the present embodiment, such a special game is performed when the hit is determined in the jackpot determination, but the form of the special game executed on condition that the hit is determined in the jackpot determination is not limited to this. Although the embodiments of the present invention have been described with reference to the embodiments, the present invention is not limited to such embodiments, and it goes without saying that various embodiments can be made without departing from the spirit of the present invention.
