DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko gaming machine, and more particularly, to a background pattern of a fluctuating design in which a plurality of symbols on a symbol display device provided on a game board of the pachinko gaming machine fluctuate according to a winning situation. And a control mechanism for performing switching control according to the game mode of the pachinko game.

[0002]

2. Description of the Related Art Conventionally, in a pachinko gaming machine, a type 1 starting port for an ordinary electric accessory, a big winning port opening at the time of a "big hit", and various winning ports on the left and right sides of the game board are provided. The player obtains the payout of a predetermined number of prize balls by causing the game balls to win the winning holes. In the winning opening, there is provided a winning opening for changing a normal symbol display device or a special symbol display device, and a plurality of symbols (numbers, picture patterns, etc.) fluctuate by winning in the winning opening. "Big hit" depending on the combination of stop symbols displayed
In this case, the condition device operates, and a large winning opening provided below the game board surface is continuously opened, during which a large number of winnings are obtained and a large amount of prize balls are paid out to the player.

[0003] Therefore, a player can obtain a large amount of prize balls once the state of "big hit" is obtained, and if the state of "big hit" continues several times, the player can win a big win. There is a high degree of interest in the combination of stopped symbols of the special symbol display device that creates a state, and depending on the symbol to be displayed and the method of stopping and changing the symbol, it may stimulate the player's entertainment.

[0004]

However, in such a pachinko gaming machine, once a state of "big hit" is obtained, a large amount of prize balls are paid out to the player, so expectation of a further "big hit" is expected. I can have a feeling, but on the contrary "big hit"
Unless the state is obtained, it is hardly expected to obtain a large amount of prize balls, and the expectation for the game will be reduced. Accordingly, obtaining a "big hit" state for a player is not only a division between winning and losing, but also relates to continuation of the game thereafter. Moreover, the pattern of the pattern for obtaining the "big hit" is relatively simple, and there is a tendency that the player gets tired in the middle of the game or decreases the frequency of going to the game hall.

[0005] The problem to be solved by the present invention is to provide a game board with a symbol display device such as a normal symbol display device or a special symbol display device, and a display to be displayed on these symbol display devices (especially a special symbol display device). In a pachinko gaming machine in which amusement is enhanced by a combination of a symbol and its background symbol, a background pattern of a plurality of symbols that starts to change based on a winning signal indicating that a gaming ball has won a specific winning port provided on a gaming board surface. Is selected and displayed from various symbol variation background patterns according to the game situation, and the symbol variation background pattern is controlled to be switched, so that the displayed symbol is effectively displayed, thereby increasing the expectation for the "big hit". It is another object of the present invention to provide a symbol display device for a pachinko gaming machine having higher entertainment.

[0006]

In order to solve this problem, a symbol display device of a pachinko game machine according to the present invention is a symbol display device provided on a game board surface of a pachinko game machine. A gist of the invention is that background symbol control means for switching and setting the background pattern of a fluctuating symbol in accordance with a game mode of a pachinko game is provided based on a winning signal indicating that a game ball has won a winning hole. .

According to the symbol display device having the above configuration,
When there is a winning signal that a game ball has won at a specific winning opening provided on the game board surface, the symbol starts to change based on the winning signal, but at that time the background pattern of the changing symbol is a pachinko game. The b switching is set according to the game mode. For this reason, the display symbol displayed in front of the background symbol is effectively produced, and by changing the plurality of types of background symbols according to the situation, the game is given a "Merihara",
The amusement of the player will be further increased.

According to the second aspect of the present invention, the background pattern is configured such that the "variable symbol" is different between a displayed symbol being changed, a "reach", and a lottery probability being high. The gist is that the switching control is performed. According to the symbol display device having this configuration, the background pattern of the fluctuating symbol is different depending on whether the fluctuating symbol is fluctuating, during “reach”, or during high probability. The background pattern makes it possible to grasp the game situation, and it is possible to further increase the expectation of the "big hit", and it can be expected that the game will be continued by inspiring the entertainment spirit.

Further, according to the third aspect of the present invention, the background pattern is controlled to be switched from a "big hit" decision to a "big hit" operation, or to be switched by a "big hit" symbol number. Things. According to the symbol display device having this configuration, from the determination of the background pattern “big hit” to the “big hit” operation,
Alternatively, it is possible to efficiently switch the background pattern by performing switching control based on the symbol number of “big hit”.

Further, according to the present invention, the background pattern is controlled to be switched by a symbol number of "big hit" or a random number designated by a background character during opening of a special winning opening. It is. According to the symbol display device having this configuration, the switching control can be performed efficiently.

Each of the ordinary symbol display device 24 and the special symbol display device 2 has a minimum probability and a maximum probability of displaying a "hit"("bighit" in the special symbol display device 2) symbol. The probability of the normal symbol display device 24 displaying “3” or “7” as “hit” is 10/100 in the case of the lowest probability and 97/100 in the case of the highest probability.
It is. In addition, the probability that a “big hit” occurs in the special symbol display device 2 is 1/313 for the lowest probability and 5/313 for the highest probability. If either of them shifts to the highest probability, the other also shifts to the highest probability. I do.

The "big hit" here means that the symbol displays 2a, 2b and 2c of the special symbol display device 2 all display the same symbol. There are 39 combinations of symbols that cause a "big hit", and among them, there are 19 combinations of display symbols called "specific symbols". Table 1 shows the combinations of the symbols. When a "big hit" occurs, the condition device is activated, and operations such as the start of a "demo game" specific to the "big hit" and the opening of the special winning opening 6 are started.

[0025]

[Table 1]

FIG. 4 shows a probability transition pattern of the special symbol display device 2. The lottery probability at which the "win" of the ordinary symbol display device 24 and the "big hit" of the special symbol display device 2 are displayed is usually set at the lowest probability, but the special symbol display device 2
If a "big hit" occurs and the "big hit" occurs in a specific symbol, the lottery probability shifts to the highest probability from the end of the operation of the condition device until the next "big hit" occurs I do. Further, if a "big hit" occurs in the specific symbol during the highest probability, the operation returns to the highest probability again after the operation of the condition device is completed.

When the above condition device is operated four times in succession with a specific symbol, the specific symbol does not appear at the time of the next "big hit", and only the ordinary symbol appears. Also, during this time, "reach" with specific symbols
No action is taken.

The "reach" operation referred to here is a medium pattern 2
a and the left symbol 2b are determined by the same symbol, but the right symbol 2c is changed, and the middle symbol 2a,
The left symbol 2b and the right symbol 2c refer to either a state in which the symbol is kept displayed and the symbol is continuously changing at a speed that can be recognized by the player. The occurrence of “reach” is a trigger in setting of a change in the symbol displayed on the special symbol display device 2, the change of the probability, and the like, and the setting differs depending on the occurrence state of “reach”.

FIG. 5 shows a judgment method of the special symbol display device 2. A "big hit" occurs on the special symbol display device 2,
The display and control of the symbol that activates the condition device are performed by a counter using random numbers.
The counter measures a frequency, a cycle, a time interval, and the like. In the present display device, a random number A for determining whether or not the symbol displayed on the special symbol display device 2 is a “big hit”
A counter, a random number B counter for determining a symbol at the time of “losing”, and a random number E counter for determining a symbol at the time of “big hit” are used.

In the random number A counter for judging "big hit", "0" is inputted as an initial value when the power is turned on, and then "1" is added every time there is an interrupt, until the final value is "312". When the added value advances, the value returns to "0" again and the counting is repeated. The cycle is 0.641 seconds.

The random number B counter is a counter for determining each stop symbol of the middle symbol 2a, the left symbol 2b, and the right symbol 2c when the displayed symbol is determined to be "losing". In the B counter, each of the symbols 2a, 2b, and 2c has one byte, and the B counter itself has three bytes. The configuration is such that for the middle symbol 2a, which is the first byte, "0" is given as an initial value at the time of power-on, and thereafter "1" is added by "1" each time an interrupt occurs, similarly to the A counter. After adding up to "38" and counting up to the end value, counting is started again from "0". The left symbol 2b, which is the second byte, is given "0" as an initial value when the power is turned on, and is incremented by "1" each time the count of the first byte returns from "38" to "0". . When the added value advances to the final value "12", the value returns to "0" again, and a new addition is started.

Further, the right symbol 2c, which is the third byte, is provided with an initial value "0" when the power is turned on, and after the counter value of the second byte returns to "0", "1" is added.
The count from "0" to "12" is repeated. The random number B counter repeats the above process from the end of the series of processes until the next reset interrupt.

The random number E counter is a counter for determining a stop symbol of each of the symbols 2a, 2b, 2c when the random number A counter determines "big hit". The initial value at the time of counting is “0” when the power is turned on, like the other counters, and 1 is added every time an interrupt occurs. The closing price is “38”. When the count advances to the closing price, the count is cleared, and the count is repeated from "0" again.

FIG. 6 shows a symbol display method of the special symbol display device 2. The values counted above are taken out each time the game ball wins the first kind starting port 4 and the first kind starting port switch 44 detects the winning, and is displayed by the value taken out at that time. Is determined. When a winning is detected by the starting port switch 44, the value of the random number A counter at that time is taken out and stored. The number of storages is a maximum of five sets. The stored value is determined immediately before the middle symbol 2a starts to fluctuate, and it is determined whether the stored value is a "big hit".

The judgment is made based on whether or not the stored value is the same as the set value. If the probability is low, it is "3", and if it is high, it is "3, 7, 11, 13, 17". In this case, it is determined to be "big hit", and if it is another value, it is determined to be "out". When it is determined as “big hit” by this determination, the symbol corresponding to the value of the random number E counter at that time is displayed as a “big hit” symbol, and when it is determined as “losing”, the symbol corresponding to the random number B counter is displayed. Missing "symbol is displayed.

FIG. 7 shows the direction in which the special symbol display device 2 installed on the surface of the game board 10 fluctuates. The state of the fluctuation of the middle symbol 2a, the left symbol 2b, and the right symbol 2c, which starts to change when the display symbol of the ordinary symbol display device 24 displays "hit", is shown in FIG. Two types are set, one in which the symbol also changes from top to bottom, and the other in which one of the symbols changes from bottom to top as shown in FIG. 4B.

The above-mentioned symbol variation method includes "acceleration variation" for scrolling while accelerating from a stopped state, "deceleration variation" for scrolling while gradually decelerating, and "high speed" for scrolling at a constant high or low speed. And "low speed fluctuation", "frame feed fluctuation" which repeats scrolling while stopping at a certain symbol and maintaining a constant speed until the next symbol, and "reverse fluctuation" which fluctuates one symbol from the bottom to the top. Several kinds of change patterns are set according to the combination, and a change pattern according to the game situation is selected and displayed. Table 2 shows these fluctuation names, fluctuation contents, and fluctuation pattern names (variation types) used.

[0038]

[Table 2]

FIGS. 8A to 8G show the basic patterns of symbol fluctuation in the symbol display device. The above-mentioned symbol change is performed for each of the middle symbol 2a, the left symbol 2b, and the right symbol 2c, and the basic pattern that is the basis of the combination is the middle symbol 2a,
The left symbol 2b and the right symbol 2c start to fluctuate while accelerating from top to bottom in the order, change to high-speed fluctuation after a certain period of time, further continue high-speed fluctuation for a certain period of time, and then perform deceleration fluctuation. This is a fluctuation that stops after a certain continuation.

When a game ball wins in the first-type starting port 4, the middle symbol 2a starts to accelerate and fluctuate (a), and after a certain period of time, the left symbol 2b starts to accelerate and fluctuate. Turns to high-speed fluctuation (b). After performing a predetermined fluctuation for a certain period of time, the left symbol 2b changes to high-speed fluctuation, and the right symbol 2c starts accelerating fluctuation (c). Here, each symbol is medium symbol 2
The symbol a and the left symbol 2b both fluctuate at a high speed, the right symbol 2c fluctuates at an accelerated speed, and all three symbols fluctuate. After performing this change for a certain period of time, the right symbol 2c changes to a high-speed change (d), and all three symbols perform a high-speed change for a certain period of time.

Next, the middle symbol 2a starts deceleration fluctuation and then stops (e), while the other two symbols continue high-speed fluctuation. After the middle symbol 2a stops and the symbol is fixed, the left symbol 2
After deceleration fluctuation (f) in order of b, right symbol 2c, it stops and three symbols are fixed and displayed (g). There are 39 types of symbols for the above-mentioned change in the middle symbol 2a, and the symbols from 1 to 13 and characters are displayed on the symbols. The 13 symbols are available in three colors, purple, blue and red. In other words, if the same number is used, there are three symbols displaying the same character for each color.

These symbols are scrolled sequentially from purple No. 1 and then to purple No. 13. When the purple symbols are scrolled, the blue symbols are scrolled in order from the first, and when all the blue symbols are scrolled, the red symbols are scrolled in order from the first. When the scroll fluctuations for all 39 pages have been completed, the scroll fluctuations from purple No. 1 are repeated again.

There are 13 types of symbols displayed on the left symbol 2b and the right symbol 2c. The displayed symbols have no coloration in both symbols, and the numbers and characters from 1 to 13 are displayed.
The scroll is changed in order up to. When the fluctuation is advanced to 13, the flow returns to 1 again, and the scroll fluctuation is repeated until the symbol is determined and stopped. When two numbers are displayed together with this character, "reach" is obtained, and when three numbers are displayed, "big hit" is obtained, and the condition device is activated.

FIG. 9 shows the “variation pattern before reach”. The “pre-reach fluctuation pattern” refers to a state in which the left symbol 2b that once passes through the “reach” is changed after the middle symbol 2a stops, and the “reach” occurs in the opposite direction. . As for the fluctuation pattern, after the middle symbol 2a is stopped and determined from the high speed fluctuation, the left symbol 2b starts the deceleration fluctuation while the right symbol 2c continues the high speed fluctuation (a). The left symbol 2b that has started to decelerate (b) once passes the symbol in which "reach" is established, but fluctuates in the opposite direction after passing (c). The passing symbol and the fluctuation in the opposite direction are both only one symbol. By changing the left symbol 2b in the opposite direction, the middle symbol 2a and the left symbol 2b are determined, and "reach" is established by displaying the symbol (d).

The fluctuation pattern indicating “reach” is
There is a different variation pattern for each lottery probability that a “big hit” occurs, and the variation pattern is “basic pattern”, “reach A”, “reach B”,
There are seven patterns of “reach C”, “reach D”, “reach E”, and “variation pattern before reach”.

In addition, there are five variation patterns at the time of the high probability, which are "basic pattern", "reach A", "reach A '", "reach D", and "variation pattern before reach". Here, the “basic pattern”, “reach A”, “reach D”, and “variation pattern before reach” perform the same variation pattern regardless of the low probability and the high probability.

FIG. 10 shows the variation patterns of (a) reach A, (b) reach B, and (c) reach C, which are the variation patterns at the low probability. The fluctuation pattern of "reach A" is such that the middle symbol 2a and the left symbol 2b stop at the same symbol, and "reach" occurs, and at the same time, the right symbol 2c shifts to low-speed fluctuation. The right symbol 2 that is changing at low speed,
From the symbol in which the "big hit" occurs to the one symbol ahead, it fluctuates and then shifts to the low speed variation again, stops the right symbol 2c, and the symbol to be displayed is determined.

The fluctuation pattern of “reach B” is the middle pattern 2
a and the left symbol 2b determine the display symbol, and simultaneously with the occurrence of "reach", the right symbol 2c shifts to low-speed fluctuation. The right symbol 2c that has been subjected to the low-speed fluctuation for a certain period of time fluctuates from the symbol causing the "big hit" to the one symbol ahead, and thereafter shifts to the low-speed fluctuation again. The right symbol 2c temporarily stops here, and it seems that the displayed symbol is confirmed, but immediately starts the high-speed fluctuation, and performs the low-speed fluctuation again from two symbols before the symbol that becomes the "big hit", and then the "big hit" is changed. Stop and fix within one symbol before and after the symbol that occurs.

In the variation pattern of “reach C”,
The variation pattern of the “reach B” is the same as the variation pattern of “reach B” from before the two symbols of the “big hit” symbol until the low speed variation is performed again. After that, the right symbol 2c once passes through the "big hit" symbol, but fluctuates in the opposite direction to generate a "big hit". Here, the symbols that pass and change in the opposite direction are both one symbol.

FIG. 11 also shows fluctuation patterns (a) reach D and (b) reach E at the time of low probability. The fluctuation pattern of the "reach D" is that the left symbol 2b and the right symbol 2c continue to change at a high speed while the middle symbol 2a starts to shift to a low speed, and then the left symbol 2b and the right symbol 2c each change for a certain time. After that, the flow shifts to the low-speed fluctuation in order. When the middle symbol 2a and the left symbol 2b are aligned and "reach" is established, finally, the right symbol 2c is aligned and a "big hit" symbol is displayed. Each symbol performs a low-speed fluctuation followed by a frame feed fluctuation while displaying the "big hit", and then stops and is determined at the same time.

The fluctuation pattern of "reach E" is the same as the fluctuation of "reach D" until the frame feed fluctuation is performed with the symbol in which the "big hit" occurs. In the subsequent “reach E” fluctuation pattern, after the frame feed fluctuation is performed, the reverse fluctuation is further performed within one symbol while the three symbols are aligned, and thereafter the symbols are stopped and fixed.

FIG. 12 shows a variation pattern of "Reach A '" which is a variation pattern at the time of high probability. Regarding the fluctuation pattern of "reach A '", the middle symbol 2a and the left symbol 2b are stopped, and the right symbol 2c continues to change at a high speed even after "reach" is generated by fixing the display symbol (a). Then, after performing high-speed fluctuation for a certain period of time, the right symbol 2c stops and the displayed symbol is determined (b), and a "big hit" occurs.
The display of these fluctuation patterns is controlled by the symbol display device. The fluctuation patterns at the time of the high probability include “basic pattern”, “reach A”, “reach D”,
There is a "variation pattern before reach", but "reach A '"
Except for the pattern, the same operation as each variation pattern at the time of low probability is performed. Therefore, explanation is omitted.

FIG. 13 shows details of the symbol display section of the special symbol symbol display device 2 installed on the game board 10.
When the ordinary symbol of the ordinary symbol display device 24 indicates "hit" and a prize is made in the first kind starting port 4 in which the game ball is opened, the middle symbol 2a, the left symbol 2b, and the right symbol 2 of the special symbol display device 2 are displayed.
c start to fluctuate. The display area 60 in which the symbols of the special symbol display device 2 are displayed has a middle symbol 2a, a left symbol 2b, and a right symbol 2c that perform symbol variation inside the region,
The outer frame 61 attached to the outside defines the variation range of the symbol. A display area background 62 is provided around the display area 60, and a character 64 for storing and displaying up to four winning balls of the first type starting port 4 is provided below the display area background 62.

The display pattern of the middle symbol 2a, the left symbol 2b, and the right symbol 2c of the special symbol display device 2 is a combination of three colors, purple, blue, and red, and 13 characters in the middle symbol 2a. Displays a total of 39 types of symbols. Further, the left symbol 2b and the right symbol 2c do not have the same color as the middle symbol and each have 13 characters, so that 13 symbols are displayed. The displayed characters are the same for the middle symbol 2a, the left symbol 2b, and the right symbol 2c.

In addition, middle symbol 2a, left symbol 2b, right symbol 2
A background symbol 66 whose display symbol is changed according to the game situation is displayed behind the character displayed in each symbol c, and a display symbol 68 having a character such as a person is displayed in front of the background symbol 66. The background symbol 66 and the display symbol 68 are set according to the gaming situation and the lottery probability of the special symbol display device 2 and the like, and display differently according to the situation.

FIG. 14 shows a background pattern of the symbol display section.
There are three types of background symbols 66 used as the background of the display symbol 68 of the middle symbol 2a, the left symbol 2b, and the right symbol 2c, and the three types of backgrounds are combined to form several types of background variation patterns. Used according to. The opportunity for the background symbol 66 to fluctuate is that the middle symbol 2a, the left symbol 2b, and the right symbol 2c, which are the symbol display portions of the special symbol display device 2.
, And during the occurrence of “reach” due to the three symbol variations, and when the lottery probability of the special symbol display device is high.

FIG. 15 shows a background variation pattern. (A) There are three background change patterns during the change of the symbol display sections 2a, 2b, 2c. In the pattern 1, only the symbol A is displayed. In Pattern 2, the symbols A and B are displayed alternately. In Pattern 3, the symbols A and B are displayed in order from the symbol A, and after the symbol C is displayed, the symbol A is repeatedly displayed again. (B) There are two types of background variation patterns during occurrence of “reach”. In pattern 1, the symbol A and the symbol B are displayed alternately and repeatedly. In pattern 2, the symbols A, B, C, B, and A start from the symbol A. Is displayed repeatedly. Further, (c) when the lottery symbol related to the special symbol display device 2 has a high probability, as in the case of “reach” occurring,
Repeatedly display B, C, B, A from the pattern of A 1
Only patterns. Since these background patterns are the background symbols of the display symbol 68, the symbol display portions 2a, 2
If b and 2c perform scroll fluctuation such as frame feed, the fluctuation is performed accordingly.

FIG. 16 shows a symbol displayed on the display area background 62. (A) shows a symbol displayed when the lottery symbol according to the special symbol display device 2 has a low probability,
(B) shows a symbol displayed when the probability is high. Three types of symbols are displayed on the display area background 62 according to the low probability and the high probability, respectively, and these are combined to form a plurality of display area background variation patterns. This change pattern starts to change according to the game situation, and the trigger of the change is the symbol display units 2a, 2b, 2
The symbol c is changing, "reach" is occurring, and the probability is high.

FIG. 17 shows a display area background variation pattern. (A) There are three display area background variation patterns at the time of low probability, pattern 1 displays only the symbol of (A), and pattern 2 displays the symbols of (A) and (B) alternately and repeatedly. Further, in pattern 3, the symbols (A), (B), (C), and (A) are repeatedly displayed. In addition, two patterns are set as the display symbols during the occurrence of “reach” at the time of low probability, and the pattern 1 displays the symbols (A) and (B) alternately, and the pattern 2 shows the symbols (A) to (B). , (C), and (B), the symbols are repeatedly displayed.

The display area background 62 at the time of high probability is of three types (D), (E), and (F). Characters and notices are displayed on the upper part 69 of the display area background, so that the player can play the game. The user is notified of the situation (in the upper part 69 of the display area background, the character "CHANCE TIME once more" is displayed). These display area backgrounds 62 fluctuate in response to the occurrence of “reach” at the time of high probability and at the time of high probability, and one pattern at the time of high probability and two patterns during the occurrence of “reach” at the time of high probability A background variation pattern is set.

The display area variation pattern at the time of high probability repeatedly displays the display area background in the order of (D), (E), (F), (E), and (D). In addition, during the occurrence of “reach” at the time of high probability, the symbols (E) and (F) are alternately displayed in pattern 1, and in pattern 2, similarly to the display area background variation pattern at high probability ( (D), (E), (F), (E), and (D) are repeatedly displayed in the display area background. The display area background 62 is different from the background pattern 66 of the symbol display section in the symbol display sections 2a and 2a.
The scroll does not fluctuate with the fluctuation of b and 2c. Therefore, a variation pattern set in response to the game situation is displayed.

However, in a display area 60, under a certain situation, all the symbols currently displayed are deleted, and a specific symbol is displayed according to the situation. The situation means that the symbol display units (2a, 2b, 2c) change during the waiting of the gaming machine, from the "big hit" determination to the start of the operation, during the "big hit" operation, and after the end of the "big hit" operation. Until the start, and at the time of fraud detection. When these situations occur, the display area 60, such as the display area background 62, the symbol display portions 2a, 2b, 2c, and the background symbol 66, which have been displaying various symbols.
Are deleted, and the inside of the display area 60 becomes one large display screen.

The stand-by state of the gaming machine refers to a state in which power is supplied to the gaming machine main body and a case where there is no fluctuation within 120 seconds after the fluctuation of the special symbol display device 2 is completed. Is displayed repeatedly. The demonstration screen shows 13 types of characters used when the symbol display units 2a, 2b, and 2c change, a background symbol,
Then, eight types of demonstration screens are constructed and displayed by combining the demonstration screen numbers in which the configuration such as the arrangement is set.

Further, on the demonstration screen until the "big hit" is determined and the operation is started, a symbol for notifying the "big hit" is first displayed. After that, among the eight demonstration screens, a display corresponding to the symbol for which the "big hit" has been determined starts to be displayed.

Further, even during the "big hit" operation, the background pattern 66 and the like are deleted. When the "big hit" occurs, the big winning opening 6 such as a symbol display is opened, and the "demo game" is started by the operation of the condition device. In the “demo game”, a round is displayed at the same time as opening the special winning opening 6, and the description of the “demo game” is displayed for the first time. The game is played 12 times, the "demo game" is performed after the round is displayed at the even number, the display according to the even number is performed at the odd number, and the "demo game" is displayed after the round is displayed at the 14th time. All results are displayed and explanations of future operations are displayed. The result of these "demo games" depends on whether or not the operation of the condition device has occurred in a specific symbol. If the device is operated with a specific symbol, the result of the "demo game" will be 5 or 6 wins, and will operate with a normal symbol. If you do, you will win four or less.

When the "demo game" is completed and 120 seconds or more elapse until the symbol display units (2a, 2b, 2c) start to change, the game machine is in a standby state and the demonstration screen is repeated. indicate. For the demonstration screen while the machine is on standby,
I omit it because I have already explained it. Further, when an injustice is detected during the game, all the symbols, backgrounds, and the like that have been displayed in the special symbol display unit are erased, and a symbol corresponding to the injustice is displayed. The fraud detection can be detected in all cases where the gaming machine is operating, and operates without selecting the state of the gaming machine.

FIG. 21 is a control flowchart based on winning of a game ball on the game board 10. When the game ball fired and fired by the player passes through the gate 22 while rolling in the game area (S1), the ordinary symbol of the ordinary symbol display device 24 starts to change (S2). Gaming ball is gate 22
When 5.2 seconds or more have passed after passing, the ordinary symbol of the ordinary symbol display device 24 stops changing, and the stopped symbol at that time is displayed on the ordinary symbol display device 24. The displayed symbols are numbers from "0" to "9". Here, if the game ball that has not passed through the gate 22 wins another winning opening (S3
"YES") A predetermined number of prize balls are paid out to the player (S
4) If no prize is won, it is discharged directly from the discharge port (S5).

When the number displayed by the normal symbol display device 24 is “3” or “7” (“YES” in S6), “hit” is obtained. When the probability of occurrence of “hit” is low, the hit is about 0. The first type start-up port 4 is opened for 3 seconds or about 2.0 seconds at a high probability (S7). However, when two or more game balls are won in the opened first-type starting port, the first-type starting port 4 is closed at that time even within the opening time.

When the number displayed on the ordinary symbol of the ordinary symbol display device 24 is a number other than the above (S13 "YE
S ") is" out ", and the first-type starting port 4 is not opened (S8). When the game ball wins the first kind starting port 4 (S9 "YES"), the middle symbol 2 of the special symbol display device 2 is displayed.
a, the left symbol 2b, and the right symbol 2c start to fluctuate in this order (S
10), after the game ball wins the first kind starting port 4;
If 0 seconds or more elapse, the motor stops in the same order as when the fluctuation started (S
11) Then, the symbol display is determined (S12).

However, if the change is the change stored in the character display 64 (S13: “YE
S "), when about 2.7 seconds or more have elapsed, the three symbols stop in the order in which the symbol variation started (S14). If the combination of stopped symbols is the same number for all three, the so-called "big hit" (S15 "YES"), the condition device that is activated when a "big hit" occurs is activated, and if it is any other combination, it is "losing". (S16), and no operation occurs.

There are 39 combinations of symbols in which a "big hit" occurs. Among them, there are 19 combinations of display symbols called "specific symbols", and the occurrence of "big hits" is based on this specific symbol. (S17 "Y
ES "), the lottery probability of the special symbol display device 2 and the ordinary symbol display device 24 shifts to the highest probability (S18).

When the "big hit" occurs, the first-class special electric accessory is activated, and the big winning opening 6 is opened for about 29.5 seconds (S19). If the game ball passes through the specific area winning opening 8 during opening of the special winning opening 6 or within about 2.0 seconds after the end of the operation of the first-class special electric auditors (S20 “YES”),
The continuous operation device of the electric accessory is operated (so-called “repeating operation”) (S21), and after the operation of the opening or the like is completed, the first-class special electric accessory is operated again to open the special winning opening 6 again. I do.

When the specific symbol is displayed four times in a row in the above-mentioned "re-changing" operation of the electric accessory (S22).
If the "big hit" occurs next time, an operation such as the opening of the special winning opening 6 that occurs at the time of the "big hit" is performed in the stopped and confirmed symbol of the ordinary symbol display device 24 (S23). . During this time, the “reach” for the specific symbol is not performed. The maximum winning opening 6 opening by "big hit" is 1 maximum.
It is set up to 4 times, and exceeds 14 times (S24 "YE
S ") or when 10 or more game balls are won (S2
5 "YES"), the special winning opening 6 is closed (S26).

Note that ten game balls did not win while the special winning opening 6 was open in S25 (“N” in S25).
If it is determined to be "O"), the process returns to S20, and it is determined whether or not the game ball has passed the specific area winning opening 8. If it is determined that the game ball has not passed (S20 "NO"), the special winning opening 6 is opened. Will be closed.

As described in the above embodiment, according to this pachinko game machine, the variation of the numbers of the normal symbol display device 24 is determined, and the first type opening 4 is opened when a specific number is displayed. When a game ball is awarded, the three symbols 2a, 2b, and 2c of the special symbol display device 2 start to change in order, change symbols in accordance with various change patterns, and then stop sequentially. . Therefore, the player looks at the state from the change of the symbol to the finalization of the symbol with the expectation of "big hit".

When the game situation is changing symbols, "reach"
Special symbol display device 2 in the middle and in these game situations
Since the displayed background symbols are different depending on the probability according to the above, the player can grasp the current game situation and wait for the symbol determination with expectation. In addition, immediately after the "big hit" occurs, the symbol display is completely different from the fluctuating symbol displayed so far, and a new "demo game" is displayed, so the player is watching the symbol display with interest. Will do.

In this gaming machine, a special symbol display device 2
Is the highest probability, the normal symbol display device 24 is also in the state of the highest probability, and therefore, there is a winning of the game ball in the first type starting port 4 and the symbol for driving the normal symbol display device 2 (in this embodiment, " 3) and “7”), the frequency of driving the special symbol display device 2 increases,
It will stimulate further interest.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, it is possible to appropriately change the design of the display area background and the background design and add the number of variable patterns in the above-described embodiment, thereby further increasing the entertainment and the interest of the player.

[0086]

As described above, according to the pachinko gaming machine of the first aspect, based on a winning signal to a specific winning port on a game board, a plurality of background symbols are used to generate a predetermined gaming situation. By performing the switching control at the opportunity, it is possible to efficiently perform the switching control of the background symbol, and the switching of the background symbol can increase the player's expectation of the "big hit". Furthermore, the winning of the specific winning opening can be confirmed very easily with the background pattern without checking the detailed part of the symbol display surface such as letters, numbers, symbols or characters, and it is possible to quickly check the pachinko game later. This makes it possible to take appropriate measures.

According to the second aspect of the present invention, a plurality of background change patterns are switched and displayed when a predetermined game situation occurs, so that the display symbol during the “reach” change can be effectively displayed. And the probability state can be easily identified by the background pattern.
It can be expected that the player will continue playing without getting tired.

Further, according to the third aspect of the present invention, the switching control from the determination of the "big hit" to the operation is performed by the symbol number, so that the background symbol can be switched and displayed efficiently and effectively. Further, by making the symbol in the "big hit" a different symbol from before, various variations in the game situation are provided, and the effect of increasing the expectation and satisfaction of the player is produced. Furthermore, in response to the setting of the symbol number, it becomes possible to switch and display a very different type of background pattern in response to the "big hit" operation,
It is possible to give various different feelings of expectation to a single prize payout operation that occurs at the time of a “big hit”. Further, even if the pachinko game is continued for a long time, a new taste can be always felt.

According to the fourth aspect of the present invention, since the background pattern can be switched in various ways based on the random number value, the special background pattern that appears randomly can be changed.
It is possible to realize on a screen of a symbol display device a new sense of taste from which the regularity of appearance of a background pattern has been removed. In addition, since the setting is the occurrence of a predetermined game situation, a large-scale device for control is not required.

Since these symbol displays relate to the background symbol of the symbol display device provided at the center of the game board surface which the player pays the most attention to, the player changes the symbol and the plurality of variation patterns. Increases interest,
In addition, since it has a possibility of obtaining a large amount of prize balls, the player can have a sense of joy and can further contribute to the development of the game industry.
