Abstract

PROBLEM TO BE SOLVED: To give newly interesting feeling and to increase the expectation for a big prize by converting image information during a variable display operation in a device, which gives a specified prize status when the variable display operation stops, and a specified combination of images is obtained. SOLUTION: When a ball is put into a start prize port 11, a big prize is judged, an image displayed at stop is determined, and a variable display operation stop pattern is selected, and then, a variable display operation starts at left, middle, and right display parts 50a to 50c of a special image display device 43, after a specified time is elapsed, images move back based on the variable display operation stop pattern. Next, the variable display operation starts again based on the variable display operation stop pattern, and stops, then images, which are determined by extracted values such as those of a big prize determining random L counter, are displayed at the display parts 50a to 50c. For selecting a variable display operation stop pattern, if the big prize status occurs, an extracted value of the first byte of the random B counter is read, which selects the variable display operation stop pattern.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, and more particularly to a pachinko gaming machine capable of converting and controlling symbol information fluctuated and displayed in a reach state.

[0002]

2. Description of the Related Art Conventionally, there is a pachinko game machine that generates a predetermined privilege-added gaming state called a "big hit" during a game. In such a model, an image display device is provided on a game board surface for displaying a plurality of symbols composed of numbers, symbols, pictures, and the like by changing and stopping them based on display control means. The image display device generally has a configuration in which a plurality of display units are arranged, and can change and stop the symbols for each symbol display unit. Then, when a game ball wins at a specific winning opening on the game board surface, the symbol displayed on the image display device starts to fluctuate, and after a predetermined time fluctuates, the symbol is stopped on a plurality of display portions of the image display device. Is displayed, and the stop display symbol constitutes a "big hit" in the case of a specific combination as in the example shown in FIG. 18, and becomes "out" in the case of other combinations. In the case of the "big hit", a large winning port on the game board surface is continuously opened to enable a large number of winnings, and a large amount of prize balls are paid out by winning during that time.

[0003] In the pachinko gaming machine,
In order to increase the player's expectation of the "big hit" and further improve the fun of the game, for example, the image display has three display portions in a horizontal row, and each of the display portions displays a symbol. First, the symbols are variably displayed on the three display units, then the symbols are sequentially variably displayed on the left and middle display units while the symbols are variably displayed only on the right display unit. After a time delay, the symbols are stopped on the right display section, and the entire display is stopped. By doing so, when the symbols are stopped at the left and middle display portions and a specific combination is left, leaving only the right display portion, that is, when a reach state is reached, finally, the right display portion is left. Until the symbols stop on the display unit, the player's sense of expectation for the "big hit" will continue to increase.

[0004]

However, recently, as described above, a gaming machine in which a part of the display unit is stopped with a delay due to the delay has become common, so that even when the player enters the reach state, the player can continue to play. It is becoming less exciting, and there is a demand for a gaming machine that can enjoy a fresher gaming sensation and that further increases the expectation of "big hits".

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and provides a gaming machine that can enjoy a fresher game feeling than the conventional model, and has a higher expectation of "big hits", thereby further increasing interest. The purpose is to provide.

[0006]

According to a first aspect of the present invention, there is provided an image display device comprising symbol information comprising a plurality of symbols, wherein the image display device is configured to sequentially change and display the symbols based on display control means and then stop and display the symbols. In a gaming machine that generates a predetermined privilege-giving gaming state when a stop display symbol becomes a specific combination, symbol information conversion control is performed by a display control unit on the symbol that is variably displayed. .

According to the first aspect of the present invention, since the symbols displayed in a variable manner can be changed, it is possible to give the player a fresh feeling of playing.

According to a second aspect of the present invention, the image display device has a plurality of display portions, and the symbols are stopped and displayed while leaving at least one display portion of the image display device. The symbol which is variably displayed is converted and controlled according to the stop display symbol on the other display unit.

According to the second aspect of the present invention, the symbols can be changed and displayed in a controlled manner in accordance with the symbols which have been previously stopped, so that a fresh game feeling can be given and the interest can be enhanced.

[0010] The invention according to claim 3 is a specific combination in which a symbol is stopped and displayed on a plurality of other display portions except for the one display portion, and a privilege-giving game state is produced depending on the stop display symbol on the remaining display portions. In the reach state, the symbols variably displayed on the remaining display units are converted and controlled according to the stop display symbols on the other display units.

According to the third aspect of the present invention, in the reach state, the symbols which are still displayed in a variable state are converted and controlled in accordance with the symbols which have already been displayed in the stopped state. The atmosphere and the game feeling received are different from the atmosphere and the game feeling received from the normally fluctuating display symbol in the non-reach state before the conversion control, and the freshness and excitement for the game can be increased.

A fourth aspect of the present invention is characterized in that, in the third aspect, the conversion control is performed so as to increase the variable display frequency of the same symbol as the symbol that is the specific combination that causes the privilege-added gaming state.

According to the fourth aspect of the present invention, in the reach state, the same symbol as the combination that generates the privilege-giving game state is frequently displayed in a fluctuating manner. In addition, the degree of excitement for a game can be increased so as to be incomparable with conventional gaming machines.

According to a fifth aspect of the present invention, the display control means includes:
It is characterized in that the conversion control mode of the fluctuation stop symbol and the symbol information is determined by the numerical value at a predetermined time of the random counter, the numerical value of which changes at regular intervals. According to the fifth aspect of the present invention, by the numerical value of the random counter,
Since the conversion control mode of the fluctuation stop symbol and the symbol information is determined, the conversion control mode becomes random, and the freshness and fun are further increased.

The symbol change in the ordinary symbol display device 41 and the special symbol display device 43 is performed by a display control device. This display control device is incorporated in a main base of the control system of the pachinko gaming machine shown in FIG. The main board incorporates a display control device, an input / output interface, a CPU, a RAM, and a ROM.

The display control device will be described in more detail. The display control device comprises: a symbol information storage ROM for storing symbol information; and a symbol information stored in the symbol information storage ROM from the symbol information storage ROM.
It consists of a display symbol information processor that reads out and performs arithmetic processing according to the instruction of the PU to create display symbol information, and a plurality of counters. The display symbol information processor,
It has a symbol information conversion means described later in detail.

As shown in Table 1, the counter in this embodiment is a random A counter, a random B counter,
It consists of 11 types of random L counter, random D1 to D2 counter, random E1 to E3 counter, random F1 to F2 counter, and random G1 counter.

[0028]

[Table 1]

The random A counter is a counter for judging a jackpot or a miss, and its numerical range is "0".
~ '270'. This random A counter starts from “0” when the power of the pachinko gaming machine is turned on, is incremented by one every predetermined interruption time (for example, 2.731 ms), and after a predetermined time (after 0.740 seconds in this example). When the numerical value becomes '270', the value returns to '0' again and the above addition is repeated. The value of the random A counter is extracted when the game ball wins the first kind starting port 11 and is detected by the special symbol change start switch 55, and is compared with a predetermined jackpot value to determine whether or not the jackpot is a jackpot. Is determined. In addition, before the determination of the jackpot is completed, the game ball may win the first-type starting port 11 and the value of the random A counter may be extracted again. A maximum of four numerical values, excluding the numerical value currently being determined, are stored in the corresponding storage area of the RAM in the control system, and are sequentially subjected to the determination.

During the interrupt time, a series of program processing repeatedly performed in the pachinko gaming machine, that is, a method of processing the lamp lighting at the time of a big hit or a miss, including the processing of various counters, the type of output sound, and the pattern Is performed, and a series of program processing is repeatedly performed for each interruption time.

The random B counter is composed of 3 bytes. The first byte is used as a random b1 counter, the second byte is used as a random b2 counter, and the third byte is used as a random b3 counter. It is used to determine a lost symbol to be stopped and displayed on the display device 43.

The first byte (b) of the random B counter
The first display is the left display unit 50a, the second byte (b2 counter) is the middle display unit 50b, and the third byte (b3 counter).
Corresponds to the symbol on the right display section 50c. The b1 to b3 counters are respectively configured with numerical values of '0' to '12', and are all '0' when the power is turned on. Then, the value of the b1 counter is equal to the interruption time (2.73).
1ms), the value of the b2 counter is incremented by 1 and increased to '12'. When the value returns from '12' to '0' again, the value of the b2 counter is incremented by '1' and the addition is repeated. As a result, the value of the b2 counter increases to '12' and returns to '0' again, so that the value of the b3 counter is incremented by '1'.

In the addition of "1" in the b1 counter, if the series of program processing ends earlier within the interruption time, the next addition processing is performed by using the remaining time. This is because the time required for the series of program processing varies depending on the state of the gaming machine, i.e., a game waiting state, during a game, or during a big hit, etc. This is because unless the next processing is performed using the time, at least “1” cannot be added to the b1 counter within the interrupt time. The cycle in which the numerical values of the b1 to b3 counters make a cycle and all three become '0' is 6.000 seconds at the maximum.

Symbols corresponding to the numerical values of the b1 to b3 counters are assigned in advance. And
Each time the winning symbol is detected by the special symbol change start switch 55, the combination of numerical values extracted from the b1 to b3 counters causes a left display unit 50a, a middle display unit 50b, and a right display unit of the special symbol display device 43 to be lost. The stop symbol displayed on 50c is determined. Also, a predetermined number of extracted values of the b1 to b3 counters are stored in a lost symbol storage area of the RAM in the control system. In this example, up to four extracted numerical values are stored except for the lost symbol being displayed. When the symbol determined by the extracted numerical values of the b1 to b3 counters matches the big hit symbol, a value different from the extracted numerical value, for example, the immediately preceding numerical value in b1 is stored.

At the time of a big hit, the random L counter displays the left display part 50a and the middle display part 50 of the special symbol display device 43.
b, to determine the same stop symbols aligned with the right display unit 50c. This random L counter is “0” to “12”.
When the power is turned on, the processing is repeated starting from "0", adding "1" at every interruption time, and returning to "0" again when reaching "12". The round L counter takes 0.035 seconds. Random L
Table 2 shows an example of the symbols assigned to the values of the counter. The value of the random L counter is the first type starting port 1
A single winning prize ball is extracted when detected by the special symbol change start switch 55, and a maximum of four prize balls are stored in the RAM except for the symbol being displayed as a big hit.

[0036]

[Table 2]

The pachinko gaming machine of this example is a probability varying model, and the jackpot symbols corresponding to the extracted value of the random L counter are “3”, “7”, “OL symbol”,
When the jackpot symbols are aligned in any of the “President's symbols”, in addition to the occurrence of the jackpot gaming state, a probability change (also referred to as a probability change) is generated, and the state changes from the low probability state to the high probability state. Note that a symbol that causes a probability change is called a positively-variable symbol, and other symbols are called normal symbols.

The random D1 counter is usually used to determine whether or not a symbol has hit or missed. The random D1 counter has a numerical value from "0" to "99". When the power is turned on, the counter starts from "0" and changes to "1" every interruption time. After the addition reaches '99', the addition is repeated starting from '0' again. The cycle time of the random D1 counter is 0.273 seconds. The value of this random D1 counter is extracted each time a game ball that has passed through the ordinary symbol variation start gate 13 is detected by the ordinary symbol variation start switch 57, and up to a maximum of four except for the one for the ordinary symbol being displayed. It is stored in the RAM.

The random D2 counter is used to determine a stop display symbol when a normal symbol comes off.
It consists of '0' to '4', and as shown in Table 3, a stop symbol for each numerical value is assigned. Also, this random D2 counter is incremented by "1" at every interruption time starting from "0" at power-on, and returns to "0" again when it reaches "4", and the addition is repeated. The value of this random D2 counter is normally the symbol change start gate 13
Are extracted each time the normal symbol change start switch 57 detects a game ball that has passed through, and a maximum of four game balls are stored in the RAM except for those for the ordinary symbol that is displayed in the off state. Also,
Like the b1 to b3 counters, the random D2 counter performs an addition process after a series of program processing until the next interrupt.

[0040]

[Table 3]

The random E1 to E3 counters are required based on the conversion control of the symbol information, and are used as a jackpot stop symbol (the same symbol as the reach symbol) which finally stops fluctuating after reaching to constitute a jackpot. This is used to determine whether to use a symbol existing before the conversion or to select from among the symbols added by the conversion in consideration of the number of conversions.

The random E1 counter is used to determine a stop symbol from three symbols, and repeats numerical values from '0' to '2'. The random E2 counter is used to determine a stop symbol from five symbols, and repeats a numerical value of '0-4'. The random E3 counter is used to determine a stop symbol from 13 symbols, and repeats numerical values from '0' to '12'. A symbol is assigned to each numerical value.

When the power is turned on, the random E1 to E3 counters start from “0” and add “1” at every interruption time, and the corresponding maximum value, that is, “2” for the random E1 counter and “2” for the random E2 counter Then, after reaching "4" and "12" in the random E3 counter, it returns to "0" again and starts addition. Also, the values of the random E1 to E3 counters are extracted when the special symbol change start switch 55 detects a winning ball to the first type starting port 11, and the currently displayed random number is displayed for each of the random E1 to E3 counters. Up to 4 excluding those corresponding to the design
Are stored in the RAM. This random counter E1
The details of the symbol determination method by E3 will be described later in the description of the symbol information conversion control.

The random F1 and F2 counters are used to determine the last stop symbol which is stopped when the special symbol is converted. In this example, random F1
The counter corresponds to the random E1 counter for jackpot symbol determination that is stopped and displayed last,
From the 12 missing symbols included in the 13 basic symbols before the conversion, 2 missing symbols are converted into a jackpot symbol, and when the number of missing symbols becomes 10, which of the missing symbols should be stopped and displayed Used to determine This random F1 counter repeats '0' to '9'. Also,
The random F2 counter of this example corresponds to the random E2 counter for determining the jackpot symbol which is stopped and displayed last, and is four out of the twelve missing symbols included in the thirteen basic symbols. As a result of converting the symbol into a jackpot symbol, if the number of missing symbols is eight,
It is used to determine which of the missing symbols should be stopped and displayed. This random F2 counter repeats '0' to '7'.

When the power is turned on, the random F1 and F2 counters each start from “0” and add “1” at every interruption time. Then, after reaching "9" in the random F1 counter and "7" in the random F2 counter, it returns to "0" again and starts addition. Also,
The values of the random F1 and F2 counters are extracted when the special symbol change start switch 55 detects a winning ball to the first type start-up port 11, and the random F1 and F2 counters are respectively assigned to the symbol currently displayed. A maximum of four items are stored in the RAM.

The random G1 counter is used to determine a symbol information conversion control condition of the right display section 55c in which symbols are variably displayed until the end when the reach is finally lost after the reach. In this example, the special symbol change start switch 55 starts with “0” when the power is turned on and repeats “1” and “0” at every interruption time. Numerical values are extracted at this time, and a maximum of four numerical values are stored in the RAM except for the symbol currently displayed in a variable display, and are read out when necessary.

When the extracted value of the random G1 counter is "0", twelve basic symbols (symbols before conversion)
Is converted to the same symbol as the reach symbol, with respect to the normal symbol information which is variably displayed in a predetermined order. When the extracted value of the random G1 counter is "1", two symbols before and after the same symbol as the reach symbol are converted into the same symbol as the reach symbol in the normal symbol information.

A method of determining a stop symbol for a normal symbol,
A method of determining a stop symbol for a special symbol and the like will be described in detail from the relationship with the random counter while showing a specific example. First, a method of determining a stop symbol for a normal symbol will be described. The game ball is a normal symbol change start gate 13
And the normal symbol change start switch 57 is detected, the normal symbol display unit 45 starts to change the normal symbol. At that time, there are six kinds of symbols, and the change is repeated in the order of A → b → C → d → E → 7. At this time, one symbol change time until one symbol fluctuates to become the next symbol is 0.016 seconds.

As described above, the game ball passes through the normal symbol change start gate 13 and the normal symbol change start switch 5
7 and the random D1 counter and D
The values of the two counters are extracted and stored in the RAM, respectively, and when a predetermined fluctuation time T elapses, whether one of the stored extracted values of the random D1 counter is a hit or not is determined in comparison with a predetermined value. Is determined.

With respect to the extracted value of the random D1 counter, the predetermined hit value differs between the low probability time and the high probability time when the pachinko gaming machine is a probability variation machine as follows. For example, when the pachinko gaming machine is in the low probability state, “3, 7, 13, 19, 29, 37, 43,
53, 61, 73 "are set as hitting numbers, and if any of the numbers matches the extracted value of the counter D1, a normal pattern is set as a hit, and in other cases, a hit is set. On the other hand, when the state is in the high probability state, any one of the numerical values "3 to 99" matches the extracted numerical value of the random D1 counter, and it is regarded as a hit. Further, the variation time T for determining whether or not the symbol has hit the ordinary symbol also differs between the low probability state and the high probability state rate. The variation time T in this example is
In the low probability state, the time is 29.199 seconds, whereas in the high probability state, the game ball is normally the symbol change start gate 1
3 and the first byte of the random B counter (b1
The counter is determined as shown in Table 4 according to the extracted numerical value. Whether the pachinko gaming machine enters the low-probability state or the high-probability state is determined by the value of a random L counter described later.

[0051]

[Table 4]

When it is determined that the random number D1 counter is a hit, the symbol "7" indicating the hit is stopped and displayed on the normal symbol display section 45, and the first type starting port 11 is operated by the solenoid 53. The movable piece 11a,
By expanding the opening 11a, it is expanded and opened for a predetermined time, and it becomes easy to win a prize. The opening time at this time is 0.505 seconds in the low probability state and 2.498 seconds in the high probability state. Note that, when two game balls are won while the first-type opening 11 is being widened and opened, the widening and opening is completed even before the end of the widening and opening time of the first-type opening 11. FIG. 6 is a time chart showing the relationship between the variation of the ordinary symbol and the opening and opening of the first type starting port 11.

On the other hand, the stop symbol of the special symbol is determined according to the values of the large hit determination random A counter, large hit symbol determination random L counter, and lost symbol determination random B counter (b1 to b3 counters) as follows. Is made. First, the game ball is the first kind starter 1
When the player wins 1 and is detected by the special symbol change start switch 55, a random A counter for jackpot determination (from '0' to
'270'), a random L counter for determining a jackpot symbol ('0' to '12') and a random symbol for determining a lost symbol b
1 counter ('0' to '12'), b2 counter ('0' to '12'), b3 counter ('0' to '1')
The numerical values of 2 ′) are respectively extracted and temporarily stored in the corresponding storage areas of the RAM in the control system. Then, the numerical value of the random A counter for jackpot determination is read out from the RAM, and is compared with a predetermined jackpot numerical value. At that time, when the gaming machine is in the low-probability state, the read value of the random A counter is, for example, “7”.
In the case of "1", the control system determines a jackpot, whereas in the high probability state, if the read numerical value is "71", "163", "251", it is determined that the jackpot is a jackpot, If the value is any other value, it is regarded as a deviation.

If it is determined that the jackpot has been determined, the extracted value of the random L counter for determining the jackpot symbol is read out from the RAM, and a symbol predetermined for the value is displayed on the left display section 50a of the special symbol display device 43. , Middle display section 50
b, determined as a big hit symbol in the right display section 50c. The jackpot symbols thus determined are respectively displayed on the left display unit 50a, the middle display unit 50b, and the right display unit 50c.
Is displayed as a stopped symbol after a predetermined type of symbol is variably displayed. If the extracted value of the random L counter is a specific value, that is, the jackpot symbol is the probable variable symbol, the state becomes a high probability fluctuation state, and is valid until the next time a predetermined number of times, for example, twice, the jackpot. Note that whether or not the state is in the high probability fluctuation state is stored in the RAM.

On the other hand, when it is determined that the read random A counter extracted numerical value is out of order, the extracted numerical values of the lost symbol determining b1 to b3 counters are read out from the RAM, and the b1 to b3 counters are read out. The symbol determined in advance for the numerical value of is determined as a lost symbol displayed on the left display unit 50a, the middle display unit 50b, and the right display unit 50c. The lost symbols determined in this way are the left display unit 50a, the middle display unit 50b, and the right display unit 50c.
, Various symbols are displayed as stop display symbols after being fluctuated for a predetermined time.

The change stop pattern between the change display of the special symbol and the stop display has a great effect on the player's expectation and interest in the jackpot for the currently changing game or the jackpot for the next change. is there. Therefore, in the gaming machine of this example, a selection is made from the following fluctuation stop patterns 1 to 7 according to the playing state of the gaming machine.

FIG. 7 shows a first example of the special symbol display device 43.
FIG. 8 is a time chart from the start of the seed opening to the start of the change of the symbol, and FIG. FIG.
8 and the like, the “left symbol” is a symbol displayed on the left display portion 50a, the “middle symbol” is a symbol displayed on the middle display portion 50b, and the “right symbol” is a symbol displayed on the right display portion 50c. To tell. First, when a winning in the first-type starting port 11 is detected, a jackpot is determined, a stop symbol is determined, and a variable stop pattern is selected.
0a, the middle display section 50b, and the right display section 50c start to fluctuate in the order of the symbols, and the symbols continue to fluctuate regularly on the respective display sections for a predetermined time, that is, in a predetermined order.
The fixed fluctuation time differs between the low probability time and the high probability time.
At this time, the symbol fluctuation is such that the symbol moves from top to bottom by one dot, and the fluctuation time of one dot is 0.08 seconds.

After a certain period of fluctuation, the left display unit 50a, the middle display unit 50b, and the right display unit 50c return the symbol at time H based on the fluctuation stop pattern. This symbol return is a process of returning to the predetermined symbol display order by a predetermined number, and then displaying the symbol again. For example,
The symbols are variably displayed in the order of "4" → "5" → "6" → "7". Normally, the symbols are variably displayed when the next display is "8" → "9". The symbol in the predetermined display order, for example, "9" is used as a reference, and a predetermined number, for example, "6" three times before the reference symbol "9" is replaced. '7' → '8' → '9'
Means that the display is changed.

After the symbol return, the symbol variation is continued according to each variation stop pattern, or Sa, S
After the symbols are temporarily stopped in b and Sc, the stopped symbol determined by the extracted numerical value of the random L counter for determining a jackpot or the extracted numerical value of the random B counter for determining a lost symbol is displayed in the left display section 50a and the middle display. At the time when the display is stopped and displayed in the order of the unit 50b and the right display unit 50c, the symbols are finally determined. Note that fluctuation stop patterns 1 and 4
In the case of, the symbols finally stop changing at the points Sa, Sb, Sc at which the pattern is temporarily stopped in the case of another change stop pattern. The time T0 from the symbol return time H0 to the symbol temporary stop Sa on the left display unit 50a is 0.786 seconds in the case of the fluctuation stop pattern 5, and 1.900 seconds in other cases. Table 5 shows the value of the time Ts from the first-type start opening winning to the final fluctuation stop in each fluctuation stop pattern, and Table 6 shows the values on the respective display units after the elapse of the fluctuation base time (2.731 seconds) after the suspension. These are the values of time T1 (time on the left display), T2 (time on the middle display), and T3 (time on the left display) until the symbol stops.

A method of selecting the symbol variation stop patterns 1 to 7 will be described with reference to the flowcharts of FIGS. First, as shown in FIG. 9, it is determined whether or not a big hit has occurred (S50). The determination at that time is made based on the extracted numerical value of the random A counter read from the RAM.
If the determination is a jackpot, the jackpot symbol is determined as described above, and at the same time, the extracted numerical value of the first byte of the random B counter is read from the RAM (S51), and the value (S52 to S56). As a result, the fluctuation stop pattern (S57 to S61) is selected, and the fluctuation of the symbol is stopped according to the selected fluctuation stop pattern. Table 7 shows the extracted values of the first byte of the random B counter and the fluctuation stop patterns 1, 3, 5, 6, 7 in this example.
Is a correspondence table.

[0063]

[Table 7]

On the other hand, as shown in FIG. 10, when it is determined that a loss has occurred based on the extracted numerical value of the random A counter read from the RAM (S62), the loss symbol is determined as described above. The fluctuation stop pattern is selected as follows.

At this time, in this example, the selection of the fluctuation stop pattern is different between the case where the gaming machine is in the low probability state and the case where the gaming machine is in the high probability state. That is, after the determination of the loss, it is confirmed whether the current state is the low probability state or the high probability state (S6).
3) In the case of the low probability state, the left display unit 50 of the special symbol display device 43 determined by the random B counter.
a, a variation stop pattern (S67 to S69) is selected based on the relationship between the stop stop symbols (S64 to S66) in the middle display portion 50b and the right display portion 50c, and the variation stop is performed according to the selected variation stop pattern. You. Table 8 shows the variation stop patterns 1 at the time of low probability.
It is a correspondence table of 2, 3 and a design.

[0066]

[Table 8]

On the other hand, when it is determined that there is a loss and it is confirmed that the current probability is high as shown in FIG. 11 (S70), the left display unit 50a and the middle display unit 50 using a random B counter are used.
b, when the stop symbol of the right display section 50c is left symbol ≠ middle symbol ≠ right symbol (S71), the symbol is stopped by the variation stop pattern 4 (S78).

On the other hand, if the symbols stopped by the random B counter on the left display unit 50a, the middle display unit 50b, and the right display unit 50c are left symbol = middle symbol / right symbol (S72), the random D1 counter is further added. The extracted numerical value is read from the RAM (S74, S76), and the fluctuation stop pattern 2 or 1 is selected depending on whether the numerical value of the random D1 counter is a specific value, in this example, “64” (S79, S76).
80).

Also, when the symbols stopped by the random B counter on the left display unit 50a, the middle display unit 50b, and the right display unit 50c are (left symbol / middle symbol = right symbol) (S73), the extracted value of the random D1 counter is used. Is read from the RAM (S75, S77), and the fluctuation stop pattern 3 or 1 is determined depending on whether the value of the random D1 counter is '64' or not.
Is selected (S81, S82). Table 9 collectively shows the relationship between the design and the variation stop pattern at the loss at the time of high probability.

[0070]

[Table 9]

The details of the variation stop patterns 1 to 7 will be described in detail. -Fluctuation stop pattern 1 The fluctuation stop pattern 1 is a pattern that is to be displayed at the time of the symbol return H shown in the time chart of FIG. 8, and the left display unit 50a, the middle display unit 50b, and the right display unit 50c, The symbol is replaced by a symbol located three symbols before the final stop symbol determined by the extracted value of the counter, and thereafter, is changed and displayed at 0.032 seconds per dot, and the left display portion 50a, the middle display portion 50b, and the right display portion 50c Then, when the final determined stop symbol is sequentially displayed, the stop is displayed. At the time of the final stop, the left display unit 50a, the middle display unit 50b, and the right display unit 50c
The fluctuation time changes from 6 dots before the final stop symbol. That is, 0.043 seconds before 6 dots, 0.054 seconds before 5 dots, 0.065 seconds before 4 dots, 0.076 seconds before 3 dots, 0.087 seconds before 2 dots, 1 dot before Changes the pattern in 0.098 seconds.

Variation stop pattern 2 When the final stop symbol is determined, the variation stop pattern 2 is the extracted numerical value of the second byte of the read random B counter and the left symbol that has been previously stopped for variation (the symbol corresponding to the stop symbol). According to the first byte of the random B counter (the extracted value of the first byte) or the right symbol of the stopped symbol (the extracted value of the third byte of the random B counter corresponding to the stopped symbol), the temporary pause symbol is shown in Table 10, It is determined as shown in Table 11.

[0073]

[Table 10]

[0074]

[Table 11]

Then, at the symbol return time H, the symbols to be variably displayed on the left display unit 50a, the middle display unit 50b, and the right display unit 50c are displayed in three orders based on the respective temporary stop symbols. The symbol is replaced with the symbol located in front of the symbol, and the displayed symbol is fluctuated and displayed at 0.032 seconds per dot. Left display unit 50a, middle display unit 50b, right display unit 5
Sa, S in which the temporary stop symbols are displayed in the order of 0c
At the time of b and Sc, the symbol is stopped and displayed for 0.273 seconds, and the variation base time is set to 2.785 seconds when the symbol variation is stopped on the right display unit 50c. After the elapse of the pause time, the left display unit 50a and the middle display unit 50b have 0.021 seconds per dot, and the right display unit 50c has 0.0 dots per dot.
The fluctuation starts again in 32 seconds, and after the fluctuation base time has elapsed, the left display unit 50a and the middle display unit 50b stop when they match the final stop symbol. However, the right display 5
For 0c, when the middle display unit 50b finally stops in accordance with the stop symbol, a fluctuation base time of 2.785 seconds for the right display unit 50c is set, and the fluctuation continues until the fluctuation base time elapses. When the symbol that matches the final stop symbol is displayed after the elapse of the variable base time, the symbol stops varying.

The left display unit 50a, the middle display unit 50b, and the right display unit 50c at the time of the temporary stop and the final stop.
Is 0.043 seconds 6 dots before the stop symbol and the final stop symbol, and 0.0
54 seconds, 0.065 seconds before 4 dots, 0.
076 seconds, 0.087 seconds before two dots, and 0.098 seconds before one dot.

Variation stop pattern 3 This variation stop pattern 3 is performed until a temporary stop in the same manner as the variation stop pattern 2. Then, after the elapse of the pause time, the left display unit 50a, the middle display unit 50b, and the right display unit 50c start changing again at one dot of 0.021 seconds. Stop when it matches the final stop symbol. However, as for the middle display unit 50b and the right display unit 50c, when the left display unit 50a finally stops in accordance with the stop symbol, the fluctuation base time for the middle display unit 50b and the right display unit 50c is 2.785 seconds. Is set, and the fluctuation is continued until the fluctuation base time elapses with a fluctuation of 0.032 seconds per dot,
After the fluctuation base time has elapsed, the fluctuation stops when a symbol that matches the final stop symbol is displayed. In this fluctuation stop pattern 3 as well, the fluctuation time changes during the temporary stop and the final stop, as in the fluctuation stop pattern 2.

[0086] The fluctuation stop pattern 4 is such that the symbols displayed on the left, middle, and right display sections at the time of returning the symbol are displayed one position before the final stop symbol determined by the extracted value of the counter. The symbol is replaced with a symbol, and thereafter, the dot is changed by 0.032 seconds, and the change of the symbol is stopped when the left, middle, and right display sections match the final stop symbol. At the time of the fluctuation stop, as in the fluctuation stop pattern 1, the fluctuation time changes from 6 dots before the stop symbol.

Variation stop pattern 5 Variation pattern 5 is a variation pattern that occurs only at the time of a big hit. In this fluctuation pattern 5, as in the fluctuation stop pattern 2, a temporary stop symbol is set as shown in Table 1.
0, as shown in Table 11. Then, the left display unit 50
a, in both the middle display section 50b and the right display section 50c, the symbol scheduled to be displayed at the symbol return time H is replaced with the symbol displayed three times before the temporary stop symbol, and the respective symbols are replaced. The display is changed at a dot of 0.032 seconds from the symbol, and the left display unit 50a, the middle display unit 50b, and the right display unit 5
In the order of 0c, the points of time Sa, S that coincide with the temporary stop symbol
At the time of b and Sc, it pauses for 0.273 seconds. At that time, a fluctuation base time of 2.785 seconds is set when the symbol is temporarily stopped on the right display section 50c. After the elapse of the pause time, the symbol change is started again, and after the end of the change base time, the symbol is stopped and displayed when the left display portion 50a, the middle display portion 50b, and the right display portion 50c coincide with the last stop symbol in this order. . The temporary stop symbol in the symbol right display section 50c is set according to the big hit symbol so as to be a symbol two to four symbols before the final stop symbol. Table 12 shows the combinations.

[0080]

[Table 12]

Variation stop pattern 6 The variation stop pattern 6 also occurs only at the time of a big hit. In the variation stop pattern 6, as in the variation stop pattern 5, a temporary stop symbol is determined (see Table 10), the symbol is returned, and the subsequent variation and pause are performed. And
When the right display unit 50c is temporarily stopped, the fluctuation base time is set for 2.785 seconds. After the fluctuation base time has elapsed, the left display unit 50a and the middle display unit 50b are finally stopped when they match the final stop symbol. And the right display section 5
For 0c, after the fluctuation base time has elapsed, after the pattern matches the final stop symbol, the pattern is temporarily stopped for 0.499 seconds when going further 14 dots, and then returns 14 dots to perform the final stop of the symbol.

The fluctuation stop pattern 7 The fluctuation stop pattern 7 also occurs only at the time of a big hit, and a temporary stop symbol is determined in the same manner as the fluctuation stop pattern 5 (see Table 10). Then, the left display unit 50a and the middle display unit 5
0b, the right display unit 50c replaces the symbol scheduled to be displayed at the symbol return time point H with the symbol three symbols earlier based on the provisional pause symbol, and each dot is 0.032 second from the replaced symbol. To change the display, and the left display section 50
In the order of a, the middle display unit 50b, and the right display unit 50c, the display symbols are temporarily stopped for 0.273 seconds at the time points Sa, Sb, and Sc when the display symbols match the temporary stop symbols. At that time, a fluctuation base time of 2.785 seconds is set when the symbol is temporarily stopped on the right display section 50c.

After the elapse of the pause time, the left display unit 50
a, the change starts again at 0.021 seconds per dot on the middle display section 50b and 0.032 seconds per dot on the right display section 50c, and after the end of the fluctuation base time, coincides with the final stop symbol on the left display section 50a. At this point, only the left display unit 50a stops changing, and at the same time, a change base time of 2.785 seconds is set again, and the symbols of the middle display unit 50b and the right display unit 50c change at 0.032 seconds per dot. After the elapse of the base time, the middle display unit 50b makes a final stop when it matches the final stop symbol. The right display section 50c temporarily stops at the final stop symbol, goes further 14 dots, pauses there for 0.0499 seconds, returns 14 dots, and stops at the final stop symbol.

Next, symbol information conversion control by the display control means will be described. This symbol information conversion control
This is performed on the symbols displayed on at least one of the left display unit 50a, the middle display unit 50b, and the right display unit 50c, and the display unit to be applied is appropriately set. In particular, when the jackpot is in the reach state, for example, the two symbols have already stopped changing with the same symbol on the two display units, and the remaining two symbols have been referred to as the two previously stopped symbols (referred to as reach symbols). When it is said that a big hit occurs when stopping at the same symbol, if the symbol information conversion control is applied to the display unit which performs the variable display of the symbol until the end, the expectation and interest in the big hit can be most efficiently increased.

FIG. 12 shows a first embodiment of the symbol information conversion control.
This will be described with reference to flowcharts in FIGS. This first
In the embodiment, the extracted value of the random A counter is determined to be a big hit, and the extracted numerical value of the predetermined random counter is changed to the symbol of the right display unit 50c in which the symbol is variably displayed until the end in the reach state. This is an example in which symbol information conversion control is performed when a specific value is reached.

In this example, as shown in FIG.
Similar to the selection of the pattern change stop pattern, it is determined whether or not a jackpot is determined based on the extracted value of the random A counter read from the RAM (S83), and if it is a jackpot, the reach expression is determined (S84). It should be noted that whether to represent the reach (S84) or directly to the jackpot (S84-b) may be selected based on an extracted numerical value of a predetermined random counter or the like.

When the reach expression is determined, it is determined (S85) whether or not to control the conversion of the symbol information based on the extracted numerical value of the first byte of the random B counter read from the RAM (S86 to S95). In this embodiment, it is determined whether or not the extracted value of the first byte of the random B counter is "0" (S86). If it is "0", the right display unit 50a of the special symbol display device 43 is displayed in advance. The symbols are displayed according to the normal symbol information in which the symbol type and the display order are determined.

On the other hand, the random B counter 1
If the extracted value of the byte is different from '0', it is further determined in order whether the extracted value of the first byte of the random B counter belongs to a specific group, and the following cases are classified.

First, it is determined whether the extracted numerical value of the first byte of the random B counter is "1", "3", or "5" (S87). If it is "1", "3", or "5", With respect to the normal symbol information on the right display unit 50c, each symbol positioned before and after the same symbol as the reach symbol (the symbol that becomes a big hit) is converted into the same symbol as the reach symbol and displayed in a variable manner (S92). ). As a result, in the right display section 50c in which the symbols are variably displayed until the end of the reach state, the same symbols as the reach symbols, that is, the symbols constituting the jackpot, are variably displayed more frequently than in the case of the normal symbol information. Expectation, interest, and excitement for the game will increase. FIG. 16 is a diagram showing conversion to “7”, which is the same symbol as the reach symbol, using virtual reels in which symbols are arranged in the order of display schedule in order to facilitate understanding of the symbol conversion. In FIG. 16, reference numeral 81 indicates the normal symbol information, and numeral 82 indicates the converted symbol information.

If it is determined that the extracted value of the first byte of the random B counter is different from '1', '3', '5', then '2', '4', '6' Is determined (S88), and in the case of '2', '4', '6', two symbols located before and after the same symbol as the reach symbol with respect to the normal symbol information on the right display part 50c. Is converted into the same symbol as the reach symbol and is displayed in a variable manner (S93). As a result, in the reach state right display unit 50c,
The fluctuation display frequency of the symbols constituting the jackpot further increases, and the sense of expectation, excitement and interest in the jackpot further increase.

If it is determined that the extracted value of the first byte of the random B counter is different from '2, 4, 6', then it is determined whether it is '7', '8', '9'. (S8
9) In the case of '7', '8', '9', the right display unit 5
For the normal symbol information at 0c, all symbols are converted so as to be the same as the reach symbol, and are variably displayed (S
94). This allows the right display unit 50c to be in the reach state.
Since the symbols displayed in the fluctuating pattern are all the same as the symbols that constitute the jackpot, the player expects that the jackpot will surely become a jackpot, and the excitement is maximized until the symbol is finally stopped and the jackpot is revealed. Is maintained at a minimum.

Further, it is determined that the extracted value of the first byte of the random B counter is different from '7', '8', '9', and then determined as '10', '11', '12'. When this is done (S90), the symbol is variably displayed on the right display unit 50c using the normal symbol information (S95). In this manner, the symbols which are displayed in a variable manner by the normal display or the symbol conversion are finally stopped according to the variation stop pattern.

Since the symbol information conversion control in the first embodiment increases the number of specific symbols (the same symbol as the reach symbol), it can be considered as a specific symbol number increase control. Since the number of symbols (losing symbols) is reduced, it can be considered as a specific symbol number reduction control. Further, in this example, the symbols at the front and rear positions of the same symbol as the reach symbol are converted, but another random number table is created, and the extracted numerical value of another random counter is used.
The conversion position of the symbol may be determined to be random based on the extracted numerical value and the random number table.

On the other hand, as shown in FIG. 13, when it is determined by the extracted value of the random A counter that the final event is lost (S96), the special symbol display device 43 is determined by the extracted value of the random B counter. It is determined whether or not the final stop symbol is a left symbol / middle symbol / right symbol (S97), and when the final stop symbol is a left symbol / middle symbol / right symbol, the right display portion 50c at which the symbol finally stops changing. Then
The fluctuation of the symbol is stopped according to the normal symbol information (S104).

Further, if the lost symbol determined by the extracted value of the random B counter is left symbol = middle symbol / right symbol (S98), that is, if the symbol finally loses after the reach state, the random symbol is further added. The extracted numerical value of the D1 counter is read from the RAM and determined whether it is a specific numerical value (for example, '64') (S100), and if different from '64', the right display unit 50c at which the symbol stops changing at last.
Then, the fluctuation of the symbol is stopped by the normal symbol information (S107).

On the other hand, according to the above (S100), the extracted value of the random D1 counter becomes a specific value (for example, '6
4 '), the extracted numerical value of the random G1 counter is read from the RAM, and it is determined whether or not it is a specific numerical value (for example,' 0 ') (S102). The symbol information variably displayed on the right display of the special symbol display is converted and controlled as follows. That is, in the normal symbol information, one symbol before and after the symbol which is the same as the reach symbol is converted into the same symbol as the reach symbol, and is variably displayed on the right display section 50c (S105). If it is determined in (S102) that the extracted value of the random G1 counter is different from '0', the right display unit 5
The symbol information displayed as 0c is obtained by converting two symbols located before and after the same symbol as the reach symbol in the normal symbol information into the same symbol as the reach symbol, and displaying them on the right display unit 50.
c is displayed in a variable manner (S106).

By performing the symbol information conversion control as described above, even if the player finally loses after the reach, the right display portion 50c that is variably displayed until the end has the same symbol as the reach symbol. Since the appearance frequency is higher than the case of the normal symbol information, the sense of expectation for the jackpot increases, and even if it is finally determined that the hit has occurred, the sense of expectation that the next hit will increase, Interest in the game increases.

On the other hand, when the lost symbol determined by the extracted numerical value of the counter is a left symbol / middle symbol = right symbol (S99), first, the extracted numerical value of the random D1 counter is a specific numerical value (for example, '64'). ) Is determined (S101). If it is different from the specific numerical value (for example, '64'), a symbol is displayed according to the normal symbol information on the right display section 50c in which the symbol is variably displayed until the end (S110).

In the above (S101), the extracted numerical value of the random D1 counter is a specific numerical value (for example, '6
4 '), the random G1
The extracted numerical value of the counter is read, and it is determined whether or not it is a specific numerical value (for example, '0') (S103). In the case of a specific numerical value (for example, '0'), the symbol information variably displayed on the right display section is converted into the same symbol as the stopped symbol one by one before and after the stopped symbol with respect to the normal symbol information. Then, it is variably displayed on the right display unit 50c according to the converted symbol information (S108). On the other hand, if it is determined in (S103) that the extracted value of the random G1 counter is different from '0', the right display unit 50c displays two symbols before and after the stop symbol with respect to the normal symbol information. Is converted to the same symbol as the symbol, and the converted symbol information is variably displayed on the right display unit 50c (S109).

According to the above-mentioned symbol information conversion control, when the symbol change is stopped in the special symbol display device 43, the left display unit 50a and the middle display unit 50a, 50b, 50c do not have to wait until the symbol stops changing. Even when the stop symbol on the display unit 50b indicates that the pattern is off early, the same symbol as the stop symbol on the middle display unit 50b is frequently displayed on the right display unit 50c where the symbol is variably displayed until the end. Therefore, the player is given a feeling that the next jackpot is likely to occur, and the sense of expectation for the next jackpot can be increased.

Next, a description will be given of a stop in the case of the big hit and the conversion control of the symbol. That is, in this case, since the number of the same symbols as the reach symbol (big hit symbol) is increased by the conversion, the stop symbol is displayed according to which of the reach symbols existing before the conversion and the new reach symbol added by the conversion. You need to decide. In this example, as shown in FIG. 14, it is first determined whether or not the current game is in a special symbol conversion state (S1).
11) In the special symbol conversion state, the random A
It is determined whether or not the jackpot has been determined based on the extracted value of the counter (S112). In the case of a jackpot, a symbol to be stopped and displayed is determined based on the extracted values of the random E1 to E3 counters according to the conversion number of the symbol (S112). S113-S
115), it is stopped and displayed by the symbol. The random E1 counter corresponds to the case where the number of converted symbols is two, the random E2 counter corresponds to the case where the number of converted symbols is four, and the random E3 counter corresponds to the case where the number of converted symbols is twelve.

For example, when the extracted value of the random E1 counter ('0' to '2') is '0', the original reach symbol (original reach symbol) is adopted as the stop symbol and '1' In the case of ', the converted reach symbol (the same symbol as the reach symbol added by the conversion) immediately before (displayed earlier) of the original reach symbol is adopted, and in the case of' 2 ', the original reach symbol The next conversion reach symbol is adopted. When the extracted value of the random E2 counter (0-5) is "0", the original reach symbol is "1", when it is "1", the converted reach symbol immediately before the original reach symbol, and when it is "2". Is the converted design two before the original reach symbol, and "3" is the converted reach symbol one after the original reach symbol, "4"
In the case of, the converted reach symbol after the original reach symbol is adopted as the stop symbol. As with the E1 and E2, a stop symbol is used in accordance with a predetermined rule for the extracted value of the random E3 counter.

In the case where the symbol is determined to be a loss and the symbol is converted, the selection of the stop loss symbol uses the extracted values of the random F1 and F2 counters as shown in (S119 to S123) of FIG. Then, it is performed in the same manner as described above. In other words, in 13 normal symbols consisting of one reach symbol and 12 missing symbols, when two of the original missing symbols (original missing symbols) are converted into the same symbol as the reach symbol, the remaining missing symbols are totaled. 10
, So a random F1 counter ('0' to '9')
Is used. In addition, when the four missing symbols are converted to the same symbol as the reach symbol, the remaining missing symbols total eight, so the random F2 counter (from '0' to
'7') is used. At this time, a lost symbol is assigned in advance to the extracted values of the random F1 and F2 counters.

FIG. 17 is a flowchart showing a second embodiment of the symbol information conversion control. In the second embodiment, apart from the normal symbol information, the normal symbol information is determined in advance by the type of the symbol,
A required number of specific symbol information different in at least one of the number and the order is prepared. Then, when the specific condition is further satisfied in the reach state, the specific display information is changed and displayed on the right display unit using predetermined specific design information instead of the normal design information.

Specifically, it is determined whether or not the reach symbol displayed on the special symbol display device 43 is a specific numerical value (“7” in this example) (S124). If the reach symbol is not “7”, the normal symbol information E When it is determined to be “7”, the normal symbol information E is used or extracted based on the extracted numerical value of another random counter (random X counter “0” to “100” in this example). It is determined which specific conversion symbol information A to D is to be used instead (S125 to S1).
34).

For example, when the extracted value (S125) of the random X counter is a specific value (for example, '0') (S126), the symbol change display is performed by the specific conversion symbol information A instead of the normal symbol information E. (S130). Since the number of the symbols in the specific conversion symbol information A is larger than that in the normal symbol information E in (S134), the control by the symbol information conversion controller can be said to be symbol information increase control.

When the extracted numerical value (S125) of the random X counter is a specific value (for example, "25") (S127), the symbol is changed and displayed by the specific conversion symbol information B instead of the normal symbol information E. (S13
1). Since the number of symbols in the specific conversion symbol information B is smaller than that in the normal symbol information E, the control by the symbol information conversion control means can be said to be symbol information reduction control.

The extracted value of the random X counter (S1
25) is a specific value (for example, “50”) (S128)
In step S132, a variable display is performed using the specific conversion symbol information C instead of the normal symbol information E. In the specific conversion symbol information C, since the number of reach symbols is increased as compared with the normal symbol information E, the control by the symbol information conversion control means can be said to be a jackpot (specific) symbol information increase control.

The extracted value of the random X counter (S1
25) is a specific value (for example, '75') (S12)
9) Instead of the normal symbol information E, the variable display is performed using the specific conversion symbol information D (S133). Since the specific conversion symbol information D includes a symbol of "Queen King" which is not normally included in the symbol information E, the control by the symbol information conversion control means can be said to be symbol type increase control.

If the extracted value (S125) of the random X counter is not the specific value, the normal symbol information E
Is displayed (S134).

In the above-described embodiment, the symbol change control in the display section in which the symbols are variably displayed until the end has been described. However, the symbol information conversion control according to the present invention is not limited to this case, and is stopped first. The symbol may be converted and controlled for the symbol to be stopped or for the symbol to be stopped second. In that case, the expectation for the appearance of the reach can be increased, and the interest can be increased.

[0112]

As shown and described above, according to the gaming machine of the present invention, the conversion of the symbol information can enhance the expectation for the jackpot, enhance the interest, and provide a fresh gaming feeling. In addition, a game can be played more happily and with excitement than a conventional gaming machine. Furthermore, by performing the symbol information conversion control using the numerical value of the random counter, the symbol conversion control mode is randomly selected during the progress of the game, so that a fresh game feeling can always be given. .
