Abstract

PROBLEM TO BE SOLVED: To provide a game machine capable of enhancing a player's hope that a desired special game condition will occur, without reducing the player's interest in the game. SOLUTION: A main CPU, if the kind of the symbol giving rise to a jackpot condition is a specific one, selects a pattern of variation based on a value of a variation-pattern-sorting random number extracted from a variation-pattern sorting table L1 (step S5 and step S6). In the variation-pattern sorting table L1, patterns of variation with longer variation times are given larger numbers of numerical values of variation-pattern-sorting random numbers so that the main CPU selects such patterns at higher rates than other patterns. Thus, patterns of variation with longer variation times (or patterns of variation with longer transitions of game conditions (ready-to-win conditions) can give rise to specific jackpot conditions at higher rates than do other patterns.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine provided with a symbol display means provided with a visible display section capable of displaying a plurality of types of symbols in a variable manner.

[0002]

2. Description of the Related Art Conventionally, a pachinko machine, which is a kind of gaming machine, is provided with a symbol display means provided with a visible display section capable of displaying a plurality of symbols in a variable manner. As a concrete example thereof, there is known a pattern display means capable of displaying a numerical pattern and a character pattern (or a picture (character) pattern) in three columns on a liquid crystal screen.

In such a symbol display means, when a game ball is won in the starting winning opening provided on the game board, the symbols in each row start changing display. Then, after the variable display, when a predetermined time has passed, for example, the predetermined symbols are displayed in the order of the left symbol → the right symbol → the middle symbol as seen from the player side, and the big hit state is obtained by the combination of the symbols,
Various states such as the reach state or the out-of-state state are formed. At this time, when the symbols in each row are displayed as the same symbol, a big hit state is formed,
The player is given the chance to win a large number of game balls.

By the way, in recent pachinko machines, in order to improve the interest of the player, various symbols are displayed from the start of variable display of the symbols in each row to the definite display of the symbols. Performance (based on the variation pattern) is being performed. As such an effect, for example, when a reach state in which specific two columns (left symbol and right symbol) are the same symbol is formed, the remaining 1 column of symbols is frame-fed, high-speed feed, Alternatively, the character is displayed by moving it.
Furthermore, the reach state formed during the symbol combination game is changed (developed), for example, normal reach → super reach → special reach, so that the player can have a higher expectation of developing into a big hit state.

In the pachinko machine, after the big hit state ends, until the next big hit state starts, the big hit probability changes to a high probability (that is, a big hit is likely to occur) and a specific big hit state (second special game state). , Provided a normal big hit state (first special game state) where the big hit probability does not change,
A device having a so-called probability variation function is known. Then, the specific jackpot state is caused by a combination of a predetermined specific symbol (or a probability variation symbol) of a plurality of types of symbols, while a normal jackpot state is a non-specific symbol other than the specific symbol (or an uncertain variation). It is designed to be generated by a combination of (patterns). Therefore, the player is playing a pachinko game while expecting a big hit state to be formed by the specific symbol.

[0006]

By the way, in the above-described effect, the player can increase the expectation of developing into a big hit state by changing the reach state, but on the other hand, the symbol is definitely displayed. It took a long time to be done. In addition, such an effect is performed for the purpose of increasing the expectation that the jackpot state will be developed, as described above, and the expectation that the specific jackpot state that the player expects to be formed is high. Was not. Therefore, as a result of complicated changes in the reach state, if a particular big hit state is not formed and a normal big hit state is formed or a deviant state is formed, the player's interest in pachinko game is impaired. I was afraid.

The present invention has been made by paying attention to the problems existing in such a conventional technique, and its purpose is to prevent the player from losing interest in the game.
It is an object of the present invention to provide a gaming machine capable of increasing the expectation that a special gaming state expected by a player will be generated.

[0008]

In order to solve the above problems, the invention according to claim 1 has a visible display unit capable of displaying a plurality of types of symbols by changing them based on a plurality of types of variation patterns. When the symbol displayed on the visible display unit is a preset first type symbol, the first special game state that is advantageous to the player is generated while the symbol display means is provided. In the case where the symbol displayed on the visible display unit is a predetermined second type of symbol, a second special game state that is more advantageous to the player than the first special game state occurs. In the gaming machine
Among the variation patterns, a variation pattern having a large number of transitions in a game state or a variation pattern having a long variation time of the symbol is configured such that a rate of displaying the second type symbol is higher. .

According to a second aspect of the present invention, in the gaming machine according to the first aspect, the plurality of types of variation patterns are selected by a selection means, and the second variation pattern is selected.
When symbols of the type are displayed, the selection means sets a high selection rate to select a variation pattern in which the transition of the gaming state is large or a variation pattern in which the variation time of the symbol is long is set high. To do.

The invention according to claim 3 is, in the gaming machine according to claim 2, wherein the selection rate when the first symbol is displayed is when the second type symbol is displayed. The gist is that it is set lower than the above-mentioned selectivity.

The invention according to claim 4 is provided with a pattern display means provided with a visible display unit capable of displaying a plurality of types of symbols by changing them based on a plurality of types of variation patterns, and is displayed on the visible display unit. In the gaming machine in which a special gaming state that is advantageous to the player is generated when the symbol shown is a predetermined symbol, among the variation patterns, a variation pattern with a large transition of the gaming state or a variation time of the symbol is long. The gist is that the variation pattern is configured so that the degree of expectation that the special game state will occur is higher.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment in which the present invention is embodied in a pachinko gaming machine (hereinafter referred to as "pachinko machine"), which is a type of the present invention, will be described with reference to FIGS.

As shown schematically in FIG. 1, a vertical rectangular middle frame 12 for setting various game components is opened / closed and attached / detached on the front side of the opening of an outer frame 11 forming the outer frame of the pachinko machine 10. It is freely assembled. And, on the front side of the middle frame 12, a game board 13 arranged inside the machine.
A front frame 14 having a glass frame for see-through protection and an upper bowl 15 are assembled and aligned so as to be openable and closable in a sideways open state. Further, at the bottom of the middle frame 12, a lower bowl plate 16,
A hitting ball launching device 17 and the like are attached. In addition, a symbol display device 18 as a symbol display means for playing a symbol combination game by changing symbols is arranged in the approximate center of the game area of the game board 13.

In addition, at a substantially central portion of the game area of the game board 13, a start winning opening 22 which is opened and closed by a solenoid (not shown) is disposed below the symbol display device 18. Further, below the starting winning opening 22, a big winning opening 23 that is opened and closed by a solenoid (not shown) is arranged. Therefore, the game ball hit in the game area of the game board 13 by the operation of the hitting ball launching device 17 wins at the starting winning opening 22, or based on the stored value of the number of starting pending balls, the symbol is displayed on the symbol display device 18. Combination games are being played.

Incidentally, the "memorized value of the number of balls reserved for starting" is stored within a range of a predetermined upper limit value (generally 4) of the number of game balls winning the starting winning port 22 during the change of the symbol. It is the value. Then, when the stored value is 0 (zero), a symbol combination game is performed by winning the game ball into the starting winning opening 22, and when the stored value is other than 0 (zero), the stored value is set to the stored value. Based on the symbol combination game. The stored value is incremented by 1 when the game ball is won in the starting winning port 22, and is decremented by 1 when the symbol combination game is started.

Next, a specific structure of the symbol display device 18 will be described with reference to FIG. The symbol display device 18 is provided with a visible display portion H including a liquid crystal screen,
As shown in FIG. 2, a plurality of columns (three columns in the present embodiment) of the first symbol 19, the second symbol 20, and the third symbol 21 are displayed in the visible display portion H for each column. Has become.
In addition, "display" means that the symbol is stopped in a state in which the player can identify the symbol on the visible display portion H, and "stop" is a temporarily stopped state called so-called fluctuation fluctuation. It also includes any of the completely stopped fixed stop states.

Further, the first to third symbols 19 to 21 in this embodiment are composed of a plurality of types (10 types) of numbers arranged as shown in FIG. More specifically, "0", "1", "2", "3", "4",
There are 10 kinds of numbers of "5", "6", "7", "8", and "9". Then, in the visible display portion H, the first to
The same or different symbols can be displayed for each row as the third symbols 19 to 21. Therefore, the player, the first to third symbols 19-2 displayed on the visual display unit H
It is possible to recognize any one of the jackpot state (special game state), the reach state, and the out-of-range state from the combination mode of 1.

For example, as shown in FIG.
When the first to third symbols 19 to 21 displayed in are the same symbol ("6"), the big hit state can be recognized from the mode of the combination. Further, when the specific two columns (for example, the first symbol 19 and the third symbol 21) are the same symbol (“6”), the reach state can be recognized from the mode of the combination. Further, when the first to third symbols 19 to 21 displayed on the visible display portion H are all different, or when one row of symbols is displayed with a symbol different from the symbols constituting the reach state (so-called detach reach )
In addition, it is possible to recognize the state of deviation from the combination mode.

Further, these plural kinds of symbols (from "0" to
“9”) is displayed in the vertical direction (variable direction A indicated by an arrow in FIG. 2) in the visible display portion H, ... → “0” → “1” → “2”.
→ ... → “8” → “9” → “0” → ... The numbers are arranged in an ascending order so as to be displayed in a variable manner (scroll display). The term "variable display" means that the symbols are not displayed in the temporarily stopped state or the fixed stopped state in the visible display section H, and are changed while changing the type of the symbol displayed in the visible display section H. Say what you are doing. Then, the visible display portion H displays any one of the plurality of types of symbols that are variably displayed for each column (the symbols are the first to third symbols 19 to 21 respectively). It is supposed to be done.

Further, in the pachinko machine 10 of this embodiment, after the big hit state ends, until the next big hit state starts, the big hit probability changes to a high probability (a big hit is likely to occur). Probability that a big jackpot state (1st special game state) is provided, which has the same probability as the normal state (when it is not the big hit state or the high probability time) without changing the big hit probability after the big hit state. It has a variable function. Then, the specific big hit state, or the normal big hit state, as described above, the combination of the symbols in the three columns (first to third symbols 19 to 21) displayed in the visible display portion H are the same symbol. When the above-mentioned aspect is formed, it occurs.

At this time, when a normal big hit state occurs, the player is given a chance to obtain a large number of game balls by opening and closing the special winning opening 23. On the other hand, when a particular big hit state occurs, in addition to the chance of winning a large number of game balls as in the normal big hit state, the big hit probability until the next big hit state starts after the big hit state, for example, 315.5 / 1 → 6
It has been changed to one-third, and the right to play a game in a state where a big hit state is likely to occur is given. Therefore, the specific jackpot state is more advantageous to the player than the normal jackpot state, and the player usually plays the game while expecting the particular jackpot state to occur. Is going.

Then, the specific big hit state, or the normal big hit state, one of the big hit states is generated based on the type of the pattern forming the combination mode of the big hit state. . That is, a plurality of types (10
Of the symbols of (type), a normal big hit state is caused by a predetermined non-specific symbol (first type symbol), and a specific big hit state is determined by a predetermined specific symbol (second type symbol) Is caused to occur. Then, in the present embodiment, among the symbols “0” to “9”, odd-numbered symbols “1”, “3”, “5”, “7”,
While "9" is defined as a specific symbol, "0 (zero)" and even numbered symbols "2", "4", "6", and "8" are defined as non-specific symbols. In addition, the specific symbol is also called "probability variation symbol" because it changes in probability after the jackpot state ends, whereas the non-specific symbol is also referred to as "non-probability variation symbol".

On the other hand, on the back side of the pachinko machine 10, a main control board (hereinafter, referred to as "main board") for integrally controlling the contents of the game.
Say. ) 24 is attached (indicated by a broken line in FIG. 1). Then, to the main board 24, a symbol control board (hereinafter, referred to as “symbol board”) 25 that executes symbol control for the symbol display device 18 is connected (shown by a broken line in FIG. 1). The symbol board 25 receives various control signals output from the main board 24, and executes symbol control of the symbol display device 18 based on various control commands constituting the control signals. Then, in the visible display portion H,
After the symbol combination game according to the control command is played, the symbols are variably displayed for each column,
The first to third symbols 19 to 21 are displayed.

Next, specific structures of the main board 24 and the pattern board 25 will be described in detail with reference to FIG. First, the main board 24 will be described. The main board 24 is a main CP as a selection unit that controls the entire pachinko machine 10.
The main CPU 26 has a ROM 2
7 and RAM 28 are connected. And ROM2
In 7, a game control program for controlling the pachinko machine 10 is stored and held. Further, in the ROM 27,
Big hit determination random number (0-630), big hit pattern random number (0
~ 9), left out symbol random numbers (0 to 9), right out symbol random numbers (0 to 9), middle out symbol random numbers (0 to 9) are stored and held. Further, the ROM 27 stores random numbers for reach determination (0 to 59) and random numbers for changing patterns (0 to 49).
Various random numbers such as the above, and various control commands corresponding to the extracted values of the various random numbers described above are stored and held.

The "variation pattern" means the first to the third.
After the symbols 19 to 21 start to change, each of the symbols 19
21 to 21 show the operation patterns of the respective symbols 19 to 21 within a predetermined variation time for each variation pattern until the predetermined symbols are fixedly stopped. That is, the variation pattern corresponds to an effect performed by the symbol display device 18, and, for example, when the reach state is reached, a specific symbol is frame-fed, fast-fed, or
Each symbol 19-2 such as operating a character other than the symbol
The operation pattern 1 is shown.

The random number for jackpot determination is the starting winning opening 2
The game ball is extracted when the game ball is won in 2, and it is determined whether or not a big hit state is achieved based on the extracted value. Then, in the ROM 27, a big hit determination random number (0 to 0
630), a predetermined jackpot value (for example, 7 and 373) for judging the jackpot state is stored, and the main CPU 26 judges that the jackpot state is reached when the extracted value matches the jackpot value. To do.

The numerical value of the big hit determination random number is 0 to 63.
0 (631 in total) and the jackpot values are 7 and 373.
, The jackpot probability of the pachinko machine 10 is 315.
It is one-third (631/2). Then, the jackpot probability is changed by increasing the number of jackpot values after the jackpot state ends when a particular jackpot state occurs. That is, in the ROM 27, a numerical value that becomes a big hit value when a particular big hit state occurs (for example, 7,373).
29, 127, 233, 295, 433, 557, 60
7, 619) is stored and the jackpot value is 2 → 10.
The probability of jackpot is increased to 1 in 63.1 (631
÷ 10).

The big hit symbol random number is a random number for determining the symbol to be finally fixedly stopped when the big hit value is extracted from the big hit judging random number. And, 0 (zero) to 9 which is the numerical value of the big hit symbol random number is 10 described above.
Corresponds to different types of designs. Therefore, when the big hit state is determined by the extraction of the big hit determination random number, the symbol corresponding to the numerical value extracted from the big hit symbol random number is determined as the symbol to be fixedly stopped.

Further, each outlier symbol random number is a random number for determining the symbol to be finally decided and stopped when a numerical value other than the jackpot value is extracted from the jackpot determination random number.
Then, the left out symbol random number corresponds to the first symbol 19, the middle out symbol random number corresponds to the second symbol 20, and the right out symbol random number corresponds to the third symbol 21. Further, the numerical values 0 (zero) to 9 that are the random symbol random numbers correspond to the above-described 10 types of symbols ("0" to "9"), like the numerical values of the jackpot symbol random numbers.

The reach determining random number is extracted when a numerical value other than the big hit value is extracted from the big hit determining random number, and whether or not the reach display is performed in the visible display portion H depending on the extracted value. Is a random number for determining. In addition, "out of reach" means, for example, in a reach state in which the first and third symbols 19 and 21 are the same symbol, the second symbol 20 is caused to display a symbol different from both of the symbols 19 and 21 and is detached. It is a state.

In the ROM 27, a predetermined reach determination value (for example, 3, 7, 13, 19, 2) of the reach determination random numbers (0 to 59) for determining the reach state is provided.
9) is stored, and the main CPU 26 determines that the reach state is reached when the extracted value matches the reach determination value (that is, produces the outly reach).

Further, the variation pattern distribution random number is stored in the ROM.
Of the plural types of fluctuation patterns stored in advance in 27,
Which variation pattern is used, the first to third symbols 19 to 21
Is a random number for determining whether to vary. And
The variation pattern is divided into a plurality of states such as a big hit state, a reach state (for out-reach), and a out-of-range state, and is tabulated, and the numerical values of the variation pattern distribution random numbers are distributed for each table. There is. Therefore, for example, when the big hit state is determined by extracting the random number for big hit determination, the main CPU 26 selects, from the change pattern table for the big hit state, a fluctuation pattern corresponding to the numerical value of the extracted fluctuation pattern distribution random number.

Further, the RAM 28 is adapted to store and retain the above-mentioned stored value stored as the number of starting balls to be reserved among the game balls won in the starting winning opening 22 and the control command calculated by the main CPU 26. . When the main CPU 26 instructs the symbol display device 18 to control symbols, the control command or the like is sent to the symbol substrate 25 as a control signal (8-bit signal MD0 to MD7) via the output port 29 and the output buffer 30. It is designed to output. In addition, the main board 24, as a control command,
Variation start command for instructing variation start and variation pattern of the first to third symbols 19 to 21, first to third symbols 19 to 2
Each symbol designating command for instructing 1 for each column and the all symbol stop command for definitely stopping the first to third symbols 19 to 21 are output.

Further, the main CPU 26 reads a control signal (INT signal or strobe signal) for instructing the pattern board 25 to read the control command which constitutes the control signal in accordance with the output timing of the control signal. Are output via the output port 29 and the output buffer 30. Then, the main CPU 26 outputs each of the fluctuation start commands, and then stores and holds each symbol designating command and all symbol stopping command in the ROM 27.
The output is made at the timing designated by the command transmission timing table shown by.

[0035]

[Table 1] The command transmission timing table shown in Table 1 shows the timing at which the all symbol stop command is output for each of a plurality of types (five patterns in this embodiment) of variation patterns 1 to 5 prepared in advance. Specifically, T1 (for example, 9360 ms) corresponding to the fluctuation pattern 1, T2 (for example, 16080 ms) corresponding to the fluctuation pattern 2,
Corresponding to fluctuation pattern 3, T3 (for example, 23960 m
The time of s) is set. Further, a time T4 (for example, 30240 ms) corresponding to the fluctuation pattern 4 and a time T5 (for example, 42440 ms) corresponding to the fluctuation pattern 5 are set. The time T1 to T5 of each variation pattern 1 to 5 is the time from the start of variable display of the symbol to the definite display of the symbol, and is predetermined for each of the variation patterns 1 to 5. This is equivalent to the fluctuation time. Further, in this embodiment, each variation pattern 1 to
5 times T1 to T5 are T1 <T2 <T3 <T4 <T5.
The variation pattern 5 has a longer variation time. That is, the longer the variation times T1 to T5, the longer the time of the effect performed on the visible display section H is.

Further, in the command transmission timing table, each symbol designating command (left /
The timing (every 2 ms) at which (right / middle) is output is shown. Then, the main CPU 26 is configured to sequentially output the left symbol designation command → the right symbol designation command → the middle symbol designation command to the symbol substrate 25 every 2 ms after outputting the fluctuation start command. In addition, the main CPU 26
Is the time T1 determined for each of the fluctuation patterns 1 to 5
With the progress of T5 to T5, all symbol designating commands are output to the symbol board 25.

Next, a specific configuration of the symbol board 25 for inputting the control command and executing the symbol control of the symbol display device 18 based on the command will be described with reference to FIG. The design substrate 25 includes a sub CPU 31 for performing design control on the design display device 18, and an input buffer 32 for inputting the control signal and the read signal output from the main substrate 24 is connected to the sub CPU 31. ing.
Further, an input port 33 is connected to the input buffer 32, and the control signal is input to the sub CPU 31 via the input port 33.

A ROM 34 and a RAM 35 are connected to the sub CPU 31. Then, in the ROM 34, a control program for performing the symbol control of the symbol display device 18 and specific control contents corresponding to the variation start command (variation pattern) (operation patterns of the first to third symbols 19 to 21) ) Is stored and held. On the other hand, RAM3
The control command and the like output from the main board 24 are stored and held at 5.

Then, the sub CPU 31 has the first to third
VD for controlling the display contents of the symbol display device 18 (visible display portion H) according to the operation patterns of the symbols 19 to 21.
A P (video display processor) 36 is connected. The VDP 36 also has a character ROM 3
7 and the video RAM 38 are connected. Then, the character ROM 37 is displayed on the visible display portion H,
For example, various image information such as images of “0” to “9” and background images are stored and held. Also, the video RAM 38
The display control information for controlling the display contents of the visible display section H generated by the VDP 36 using various image information stored in the character ROM 37 based on the control command and the like is stored and held in There is. Then, the VDP 36 converts the display control information into an image signal and outputs it to the symbol display device 18.

Therefore, the pattern substrate 25 (sub CPU 31)
When a control command is input, based on the control content corresponding to the command, the operation pattern from the fluctuation start to the definite stop of the first to third symbols 19 to 21 is controlled. on the other hand,
VDP36 produces | generates the display control information corresponding to the said control content, and controls the display content of the symbol display device 18 (visible display part H) based on this display control information. As a result, the first to third symbols 19 to 21 are displayed on the visible display portion H, and the display content on the visible display portion H is controlled according to the operation pattern of each of the symbols 19 to 21.

Next, the pachinko machine 1 configured as described above
In 0, a specific configuration for increasing the rate at which a specific big hit state occurs (or the rate at which a specific symbol is displayed) will be described according to the types of variation patterns 1 to 5.

First, five types of variation patterns in this embodiment will be described with reference to FIG. The variation pattern 1 is the first to third symbols 19 to 21 composed of the operation A.
Has become the operation pattern. To give an example of a specific operation, after each of the symbols 19 to 21 starts the variable display, an operation pattern in which the symbols are displayed in the order of the first symbol 19 → the third symbol 21 → the second symbol 20. Has become. And
In the variation pattern 1, the first to third variations are performed based on the variation time T1.
The symbols 19 to 21 are designed to be operated.

The variation pattern 2 is the first to third symbols 19 formed by adding the operation B during or after the operation A described above.
The operation patterns are ˜21. As an example of a specific operation, after the first symbol 19 and the third symbol 21 are displayed in the same symbol by the action A (at this time, the reach state is formed), and then the action B, the normal reach effect is produced. It is an operation pattern for performing. For example,
As an effect of normal reach, after the second symbol 20 is variably displayed at a speed at which the player can identify the type of symbol,
A predetermined pattern is displayed. Then, in the variation pattern 2, the game state in the symbol combination game changes into two stages, such as the start of symbol variation → normal reach, and the first to third based on the variation time T2.
The symbols 19 to 21 are designed to be operated.

The variation pattern 3 is the operation pattern of the first to third symbols 19 to 21 which is formed by adding the operation C in the middle of or after the above-described operation A and operation B. As an example of a specific operation, after the normal reach effect by the operation B, the reach state is developed by the operation C and the operation pattern is for performing the super reach effect. For example, as a production of super reach, the background of the visible display portion H is changed or a character is made to appear to display a design. The "super reach" is a reach state in which the expectation that a big hit state is formed is higher than in the normal reach. Then, in the variation pattern 3, the variation start of the symbol → normal reach →
Like the super reach, the game state during the symbol combination game changes into three stages, and the first to third symbols 19 to 21 are operated based on the variation time T3.

The variation pattern 4 is the operation pattern of the first to third symbols 19 to 21 which is formed by adding the operation D in the middle or after the above-mentioned operation A, operation B and operation C. As an example of a specific operation, after the super reach effect by the operation C, the reach state is further developed by the operation D to form the first special reach effect. For example, as the effect of the first special reach, a pattern is displayed by a background, a character, or an action of the character different from that at the time of super reach. The "special reach" is a reach state in which the expectation that a big hit state is formed is further enhanced as compared with the normal reach and the super reach. Then, in the variation pattern 4, the game state during the symbol combination game changes into four stages, such as the start of symbol variation → normal reach → super reach → first special reach, and the first to the first based on the variation time T4. The three symbols 19 to 21 are operated.

The variation pattern 5 is the operation pattern of the first to third symbols 19 to 21 which is formed by adding the operation E during or after the above-described operation A, operation B, operation C and operation D. As an example of a specific operation, after the effect of the first special reach by the operation D, the reach state is further developed by the operation E, and the operation pattern is for performing the effect of the second special reach. . For example,
As an effect of the second special reach, a pattern is displayed by a background, a character, or an action of the character different from that at the time of super reach or the first special reach. Then, in the variation pattern 5, the variation start of the symbol → normal reach → super reach → first
Special reach → second special reach, the game state during the symbol combination game changes to five stages, and the first to third symbols 1 based on the variation time T5.
9 to 21 are operated.

As described above, the variation patterns 1 to 1 of this embodiment are
In 5, the variation pattern in which the gaming state in the symbol combination game changes is a variation pattern in which the variation time is long. In addition, when the reach state is formed, the variation pattern becomes longer as the reach state develops (changes) such as normal reach → super reach → first special reach → second special reach.

Next, the fluctuation pattern distribution tables L1 to L6 to which the above-mentioned fluctuation patterns 1 to 5 are distributed will be described. In the present embodiment, six types of fluctuation pattern distribution tables L1 to L6 (hereinafter, simply “tables L1 to L6
6 ”. ) Is provided, and two types of table L are provided.
1, L2 (shown in Tables 2 and 3) are tables for the big hit state. Then, the table L1 is a table for the main CPU 26 to select a variation pattern when a particular big hit state formed by a particular symbol occurs even in the big hit state. Further, the table L2 is a table for the main CPU 26 to select the variation pattern when the normal big hit state formed by the non-specific symbols occurs even in the big hit state.

First, the table L1 (for a specific big hit state) shown in Table 2 will be described.

[Table 2] In this table L1, four types of variation patterns 2 to 5 except the variation pattern 1 are distributed, and in each variation pattern 2 to 5, a total of 50 variation pattern distribution random numbers “0” to “49” are assigned. The numerical value of is distributed by a predetermined number. Specifically, the variation pattern 2 is “0” to “11”.
12 numbers up to 12 in the fluctuation pattern 3
15 numbers up to “26”, 22 numbers from “27” to “48” are assigned to the variation pattern 4, and 1 number “49” is assigned to the variation pattern 5, respectively. .

Therefore, in this table L1, the main C
The PU 26 has a selection rate of 12/50 (24%) for selecting the variation pattern 2, a selection ratio of 15/50 (30%) for selecting the variation pattern 3, and a selection rate of 50 minutes for selecting the variation pattern 4. 22 (44%), and the selection rate for selecting the variation pattern 5 is 1/50 (2%). That is,
The selection rate at which the main CPU 26 selects each of the fluctuation patterns 2 to 5 from the table L1 becomes easier to be selected higher as the fluctuation pattern has a longer fluctuation time (or the fluctuation pattern in which the gaming state (reach state) changes more often). ing. The variation pattern 5 with the longest variation time is the main CP.
Although the selectivity of U26 is set to 1/50 (2%), which is lower than those of the other variation patterns 2 to 4, the variation pattern 5 is the table L1 among the six types of tables L1 to L6. It is distributed only to the player, and appears only when a particular jackpot condition occurs. Further, in this table L1, the fluctuation pattern 1 having the shortest fluctuation time is not distributed, and does not appear when a specific big hit state occurs.

Further, Table 3 shows a table L2 (for a normal big hit state).

[0053]

[Table 3] In this table L2, four types of variation patterns 1 to 4 except the variation pattern 5 are distributed, and in each variation pattern 1 to 4, a total of 50 variation pattern distribution random numbers "0" to "49" are assigned. The numerical value of is distributed by a predetermined number. Specifically, the fluctuation pattern 1 has five numbers from “0” to “4”, and the fluctuation pattern 2 has “5” to “2”.
Eighteen numbers up to 2 ”are displayed in fluctuation pattern 3 as“ 2
Fifteen numbers from "3" to "37" are fluctuation patterns 4
12 numbers from "38" to "49" are assigned to each.

Therefore, in this table L2, the main C
The PU 26 has a selection rate of 5/50 (10%) for selecting the variation pattern 1 and a selection rate of 5 for selecting the variation pattern 2.
18/0 (36%), the selection rate for selecting the variation pattern 3 is 15/50 (30%), and the selection rate for selecting the variation pattern 4 is 12/50 (24%). That is, the selection rate at which the main CPU 26 selects each of the fluctuation patterns 1 to 4 from the table L2 is different from that of the table L1 (in the opposite relationship), and the fluctuation pattern having a long fluctuation time (or the gaming state). It is more difficult to select a lower value as the (reach state) changes more frequently.
In other words, a variation pattern with a shorter variation time (or a variation pattern with less transition of the gaming state (reach state)) has a higher selection rate and is more likely to be selected.

In the present embodiment, three types of tables L3, L4, L5 among the six types of tables L1 to L6 are used.
Is a table for the reach state (for the outlying reach). Then, the table L3 is one symbol descending order side (-) with respect to the first and third symbols 19 and 21 forming the reach state.
The symbols arranged in one frame or on the front side) are displayed as the second symbol 20, and the main CPU 26 serves as a table for selecting a variation pattern when forming a combination of the outlying states. Specifically speaking, the first and third symbols 1
For example, when 9 and 21 are “1”, “0” is displayed as the second symbol 20, and a combination mode of “1”, “0”, and “1” is formed.

Further, the table L4 has the symbols arranged on the ascending order side (+1 frame or rear side) for one symbol with respect to the first and third symbols 19 and 21 forming the reach state, the second symbol 20.
Is displayed as a table and is a table for the main CPU 26 to select a variation pattern when forming a combination of outlying states. Specifically, when the first and third symbols 19 and 21 are "1", "2" is displayed as the second symbol 20, and the combination of "1""2""1" Such as when an aspect is formed.

Further, the table L5 is not arranged on the descending side (-1 frame) or on the ascending side (+1 frame) for one symbol with respect to the first and third symbols 19 and 21 forming the reach state. The symbol is displayed as the second symbol 20, and is a table for the main CPU 26 to select the variation pattern when forming the combination of the outlying states. Specifically, when the first and third symbols 19 and 21 are “1”, the symbols “3” to “3” other than “0”, “1 (big hit symbol)” and “2” as the second symbol 20. 9 is displayed and, for example, a combination mode of "1", "7", and "1" is formed.

Tables 4 and 5 show table L3.
(For reach state (-1 frame shift)) and table L4
(Each for the reach state (+1 frame shift)) is shown. Since Tables 4 and 5 have the same configuration, they will be collectively described below.

[0059]

[Table 4]

[0060]

[Table 5] In the tables L3 and L4, three types of variation patterns 2 to 4 except the variation pattern 1 and the variation pattern 5 are distributed, and each variation pattern 2 to 4 includes "0" to "4".
A total of 50 fluctuation pattern distribution random numbers "9" are distributed by a predetermined number. Specifically, the fluctuation pattern 2 has 33 numbers from “0” to “32”, the fluctuation pattern 3 has 15 numbers from “33” to “47”, and the fluctuation pattern 4 has 15 numbers. Two numbers "48" and "49" are assigned respectively.

Therefore, in the tables L3 and L4, the main CPU 26 has a selection rate of 33/50 (66%) for selecting the variation pattern 2 and a selection rate of 15/50 (30%) for selecting the variation pattern 3. ), The selection rate for selecting the variation pattern 4 is 2/50 (4%). That is,
The selection rate at which the main CPU 26 selects each variation pattern 2 to 4 from the tables L3 and L4 is different from that of the table L1 (in the opposite relationship), and the variation pattern having a long variation time (or the gaming state). It is more difficult to select a lower value as the (reach state) changes more frequently. In other words, the fluctuation pattern with a short fluctuation time (or
Variation pattern with little change in game state (reach state)
The higher the selection rate, the easier it is to select.

Further, Table 6 shows a table L5 (for reach state (-1 frame, +1 frame or any other pattern except the jackpot pattern)).

[0063]

[Table 6] In this table L5, two types of fluctuation patterns 2, except fluctuation pattern 1, fluctuation pattern 4 and fluctuation pattern 5,
3 are distributed, and in the fluctuation patterns 2 and 3,
A total of 50 fluctuation pattern distribution random numbers "0" to "49" are distributed by a predetermined number. In particular,
Forty-eight numbers from "0" to "39" are used for the variation pattern 2, and one number from "40" to "49" is used for the variation pattern 3.
0 numbers are assigned.

Therefore, in this table L5, the main C
In the PU 26, the selection rate for selecting the variation pattern 2 is 40/50 (80%), and the selection rate for selecting the variation pattern 3 is 10/50 (20%). That is, the main C
The selection rate at which the PU 26 selects each of the fluctuation patterns 2 and 3 from the table L5 is different from that of the table L1 (it has an inverse relationship), and the fluctuation pattern has a long fluctuation time (or the gaming state (reach state). The fluctuation pattern with a large number of transitions) is less likely to be selected. In other words, a variation pattern with a shorter variation time (or a variation pattern with less transition of the gaming state (reach state)) has a higher selection rate and is more likely to be selected.

Further, in the present embodiment, one of the six types of tables L1 to L6 is the table for the out-of-range state. And this table L
6 is a table for the main CPU 26 to select a variation pattern when a pattern of combinations of symbols that is in a detached state is formed without a reach state being formed. Specifically, when the first symbol 19 is "0", the third symbol 21 is "1" other than "0"-
Display the symbol "9", for example, "1""3""5"
Is a case where a combination aspect consisting of is formed.

Then, Table 7 shows a table L6 (for a detached state).

[0067]

[Table 7] In this table L6, only one type of variation pattern 1 except variation patterns 2 to 5 is distributed, and the variation pattern 1 is a numerical value of all 50 variation pattern distribution random numbers “0” to “49”. Are distributed. Therefore, in this table L6, the selection rate of the main CPU 26 for selecting the variation pattern 1 is 50/50 (100%). That is, when the combination of the outlying states is formed, the main CPU 26 selects only the variation pattern 1 from the table L6. Therefore, in this case, the main CPU 26 is adapted to select the variation pattern with the shortest variation time (or the variation pattern with the smallest transition of the gaming state).

Thus, in this embodiment, the table L1
The distribution of the variation patterns 1 to 5 is changed for each of L6 to L6, and the distribution pattern of the variation pattern distribution random numbers is made different for the variation patterns 1 to 5 distributed to each of the tables L1 to L6. Table 8 shows each table L
The numbers of the numerical values of the fluctuation pattern distribution random numbers distributed to the fluctuation patterns 1 to 5 of 1 to L6 are shown.

[0069]

[Table 8] As shown in Table 8, tables L1 and L2 for the big hit state
In, the number of numerical values of the variation pattern distribution random numbers distributed for each variation pattern is different. Specifically, in the variation pattern 1, numerical values are not distributed in the table L1, whereas five numerical values are distributed in the table L2. Therefore, when the variation pattern 1 is selected, the ratio (probability variation rate (%)) at which a specific big hit state is formed is (0 [number of numerical values distributed to the table L1] / 5 [table L1 + table L2 The number of distributed numerical values]) × 100 = 0 (%). Therefore, when the main CPU 26 selects the variation pattern 1, the non-specific symbols are displayed and only the normal big hit state is generated based on the mode of the combination.

In the variation pattern 2, 12 numerical values are distributed in the table L1, whereas 18 numerical values are distributed in the table L2. Therefore, when the variation pattern 2 is selected, the rate at which a specific big hit state is formed (probable variation rate (%)) can be calculated in the same manner as described above, and is (12 ÷ 30) × 100 = 40.
(%). Therefore, when the main CPU 26 selects the variation pattern 2, the ratio of occurrence of the normal big hit state is higher than that of the specific big hit state. That is, the ratio of the non-specific symbol combination mode displayed is higher than that of the specific symbol combination mode.

Further, the variation pattern 3 is the same for both tables L.
15 numerical values are assigned to each of 1 and L2. Therefore, when the variation pattern 3 is selected, the rate at which a specific big hit state is formed (probability variation rate (%)) can be calculated in the same manner as described above, and (15 ÷ 30) × 100
= 50 (%). Therefore, the main CPU 26
When the variation pattern 3 is selected, the specific big hit state and the normal big hit state are generated at the same ratio (1/2). That is, the ratios of the combination of the specific symbols and the combination of the non-specific symbols are the same.

In the variation pattern 4, 22 numerical values are distributed in the table L1, whereas 12 numerical values are distributed in the table L2. Therefore, when the variation pattern 4 is selected, the rate at which a specific big hit state is formed (probability variation rate (%)) can be calculated in the same manner as described above, and is (22 ÷ 34) × 100 = 65.
(%). Therefore, when the main CPU 26 selects the variation pattern 4, the ratio of occurrence of the specific big hit state is higher than that of the normal big hit state. That is, the ratio of displaying the combination of the specific symbols is higher than that of the combination of the non-specific symbols.

In the variation pattern 5, one numerical value is distributed in the table L1, whereas no numerical value is distributed in the table L2. Therefore, when the variation pattern 5 is selected, the ratio (probable variation rate (%)) at which a specific big hit state is formed can be calculated in the same manner as described above, and (1 ÷ 1) × 100 = 100 (%) Has become. Therefore, when the main CPU 26 selects the variation pattern 5, the specific symbol is displayed and only the specific big hit state is generated based on the mode of the combination.

As described above, the table L1 and the table L
2, by changing the number of distributed random pattern numerical values for the variable patterns 1 to 5,
A variation pattern with a long variation time (or a variation pattern with a large number of changes in the game state (reach state)) is configured to have a higher rate of occurrence of a specific jackpot state. Therefore, the player has an expectation that a specific jackpot state will be generated by the appearance of a variation pattern having a long variation time (or a variation pattern in which the gaming state (reach state) changes a lot) on the visible display portion H. Can be increased.
In addition, the player has a variation pattern (or
Even if a variation pattern with many changes in the game state (reach state) appears, without losing interest in the production content,
You can see the production until the end.

Further, the reach state tables L3 to L5 are used.
Among them, in the tables L3 and L4, the rate of selection of a variation pattern having a longer variation time (or a variation pattern in which the gaming state (reach state) changes more often) is higher than that of the table L5. Therefore, a variation pattern with a long variation time (or a variation pattern with a large number of transitions in the gaming state (reach state)) is one symbol ascending side or descending order with respect to the first and third symbols 19 and 21 forming the reach state. The proportion of the symbols arranged on the side displayed as the second symbol 20 is high. Therefore, the player is displayed as the second symbol 20 even if the out-of-position state is formed as a result of the effect produced by the variation pattern having a long variation time (or the variation pattern in which the game state (reach state) changes a lot). You can get a feeling that it was a shame to see the types of designs.

Further, tables L3 to L5 for reach state
In, the rate of selecting a variation pattern with a short variation time (or a variation pattern with a small change in the gaming state) is high. Therefore, as a result of the reach effect, when an out-of-range state is formed (out-of-range reach), by lowering the rate of appearance of a variation pattern with a long variation time, the game time is shortened and the player's game It is possible to suppress the risk of losing interest.

Next, the pachinko machine 1 configured as described above
0, the manner in which the main CPU 26 of the main board 24 selects the variation patterns 1 to 5 from the tables L1 to L6 will be described in detail with reference to FIGS. 5 and 6. Note that FIG. 5 and FIG. 6 are flowcharts in the case where a game is being played with a probability of normal times.

First, when the game ball hit in the game board 13 wins the starting winning opening 22, the main CPU 26 extracts the numerical value of the big hit determination random number (step S1). At this time, the main CPU 26 extracts the numerical value of the big hit symbol random number together with the numerical value of the big hit determination random number. In addition, when the stored value of the number of balls reserved for starting reaches the upper limit value, the main C
PU26 does not extract each numerical value of the big hit determination random number and the big hit design random number.

Next, the main CPU 26 causes the visible display portion H
In, before the variable display of the first to third symbols 19 to 21 is started (that is, before the symbol combination game is started)
First, it is determined whether or not the numerical value extracted in step S1 and the jackpot value match (step S2). Then, if the determination result is affirmative, that is, if it is determined to be a big hit state,
The main CPU 26, based on the numerical value of the big hit symbol random number extracted in step S1, finally displays the first to the first.
The third symbols 19 to 21 (which are fixed stop symbols and become jackpot symbols) are determined (step S3).

Next, the main CPU 26 determines that the type of symbol determined in step S3 is a specific symbol ("1""3").
It is determined whether or not it is "5", "7", "9") (step S4). Then, if the determination result is affirmative, that is, if it is a specific symbol, the main CPU 26 selects the table L1 for a specific jackpot state from a plurality of types of tables L1 to L6 stored and held in the ROM 27 (step S5). Further, the main CPU 26 extracts the numerical value of the variation pattern allocation random number, and based on the numerical value, the table L
A variation pattern is selected from 1 (step S6). For example, if the extracted numerical value is “30”, the variation pattern 4
If the extracted numerical value is “49”, the variation pattern 5 is selected.

After that, the main CPU 26 determines that the pattern board 2
5, the fluctuation start command based on the fluctuation pattern selected from the table L1 is output as a control signal. Further, the main CPU 26 outputs the variation start command,
Every 2ms, the first symbol 19 determined from the jackpot symbol random number
The left symbol designating command corresponding to, the right symbol designating command corresponding to the third symbol 21, and the middle symbol designating command corresponding to the second symbol 20 are sequentially output as control signals. Further, based on the command transmission timing table shown in Table 1, after the variation start command is output, the main CPU 26 outputs the all symbol stop command as a control signal when the variation time corresponding to the selected variation pattern elapses.

Further, in the symbol board 25 (sub CPU 31) to which each control signal (each command) is input, based on the command, the symbol control from the start of variation of the first to third symbols 19 to 21 to the fixed stop is performed. Run. Then, based on the flow of steps S1 to S6, the main CPU
When 26 outputs each command, the visual display unit H displays
The same specific symbol is displayed as the first to third symbols 19 to 21, and a specific big hit state is generated from the mode of combination by the symbols.

On the other hand, the determination result of step S4 is negative, that is, non-specific symbols ("0""2""4""6"
If “8”), the main CPU 26 determines that the ROM 27
The normal big hit state table L2 is selected from among the plurality of types of tables L1 to L6 stored and stored in the table (step S7). Further, the main CPU 26 extracts the numerical value of the fluctuation pattern allocation random number and selects the fluctuation pattern from the table L2 based on the numerical value (step S).
8). For example, if the extracted numerical value is “30”, the fluctuation pattern 3 is selected, and if the extracted numerical value is “49”, the fluctuation pattern 4 is selected.

Thereafter, the main CPU 26 outputs each command as a control signal to the design board 25 in the order of the fluctuation start command-> each design designation command-> all design designation command, in the same manner as described above. The symbol control is executed based on each command. And step S1
~ Based on the flow of step S4 → step S7 → step S8, when the main CPU26 outputs each command, the same non-specific symbol is displayed on the visible display portion H as the first to third symbols 19 to 21. At the same time, a normal big hit state is generated from the aspect of the combination according to the design.

If the result of the determination in step S2 is negative, that is, if it is determined that the jackpot state is not reached, the main C
PU26 extracts the numerical value of the random number for reach determination (step S9, FIG. 6). At this time, the main CPU 26 extracts the numerical values of the reach determination random number, the numerical values of the left-sided design random number, the middle-sided design random number, and the right-sided design random number. Then, the main CPU 26 determines whether the numerical value extracted in step S9 matches the reach determination value (step S10). When the determination result is affirmative, that is, when the reach state is determined, the main CPU 2
6, the first to third symbols 19 to 21 are determined in consideration of the numerical values of the respective outlier symbol random numbers extracted in step S9 (step S11). To give a specific example, when the left out symbol random number “1”, the middle out symbol random number “4”, and the right out symbol random number “3” are extracted, the main CPU 26 determines the first and the first. 3 patterns 19, 21
Is determined to be "1" and the second symbol 20 is determined to be "4". In addition, when “1” is extracted as the medium out symbol random number, the main CPU 26 sets the extracted value of the medium out symbol random number to “1” in order to prevent all symbols from becoming the same symbol. Add 1 and change to "2". As a result, the main CPU 26 sets the first and third symbols 19 and 21 to "1",
The second symbol 20 is determined to be "2".

Next, the main CPU 26 uses the second symbol 20.
It is determined whether or not the symbol determined as is a symbol arranged on the descending side or the ascending side for one symbol with respect to the symbols determined as the first and third symbols 19 and 21 (step S12). . Specifically, when the first and third symbols 19 and 21 are "1", it is determined whether or not the second symbol 20 is "0 (descending side)" or "2 (ascending side)". . And
If the determination result is affirmative, that is, if the second symbol 20 is a symbol arranged in the descending side or the ascending side for one symbol, the main CPU 26 further causes the second symbol 20 to descend by one symbol side (-1). It is determined whether or not the symbols are arranged in (shift of frames) (step S13).

Then, the main CPU 26 determines that the determination result of step S13 is affirmative, that is, if the second symbol 20 is a symbol arranged in descending order for one symbol, the ROM 2
Tables L1 to L6 stored and held in No. 7
The table L3 for the reach state is selected from among these (step S14). Further, the main CPU 26 extracts the numerical value of the fluctuation pattern distribution random number and selects the fluctuation pattern from the table L3 based on the numerical value (step S1).
5). For example, if the extracted numerical value is “30”, the fluctuation pattern 2 is selected, and if the extracted numerical value is “49”, the fluctuation pattern 4 is selected.

On the other hand, the main CPU 26, if the determination result of the step S13 is negative, that is, the second symbol 20 is a symbol arranged in the ascending order of one symbol, the ROM 27
The reach state table L4 is selected from the plurality of types of tables L1 to L6 stored and stored in the table (step S16). Further, the main CPU 26 extracts the numerical value of the fluctuation pattern distribution random number and selects the fluctuation pattern from the table L4 based on the numerical value (step S17).
For example, if the extracted numerical value is “30”, the fluctuation pattern 2 is set, and if the extracted numerical value is “49”, the fluctuation pattern 4 is set.
Select.

Further, the determination result of step S12 is negative,
That is, when the second symbol 20 is not a symbol arranged in the descending order side or the ascending order side for one symbol, the main CPU 26 determines R
A plurality of types of tables L1 stored and held in the OM 27
The table L5 for the reach state is selected from L6 to L6 (step S18). Then, the main CPU 26 extracts the numerical value of the fluctuation pattern allocation random number and selects the fluctuation pattern from the table L5 based on the numerical value (step S19). For example, if the extracted numerical value is “30”, the fluctuation pattern 2 is selected, and if the extracted numerical value is “49”, the fluctuation pattern 3 is selected.

Thereafter, the main CPU 26 outputs each command as a control signal to the design board 25 in the order of the fluctuation start command-> each design designation command-> all design designation command, in the same manner as described above. The symbol control is executed based on each command. And step S1
→ Step S2 → When the main CPU 26 outputs each command based on the flow of steps S9 to S15, the reach state is formed in the visible display portion H. Then, as a result of the reach effect, the symbols arranged on the descending side for one symbol with respect to the first and third symbols 19 and 21 are displayed as the second symbol 20, and the out-of-position state is confirmed.

When the main CPU 26 outputs each command based on the flow of step S1 → step S2 → step S9 to step S13 → step S16 → step S17, the reach state is formed in the visible display portion H. It Then, as a result of the reach effect, the symbols arranged on the ascending order side for one symbol with respect to the first and third symbols 19 and 21 are displayed as the second symbol 20, and the out-of-position state is confirmed. Furthermore, step S1 → step S2 → step S
9 to step S12 → step S18 → step S19
When the main CPU 26 outputs each command based on the flow of, the reach state is formed in the visible display portion H. Then, as a result of the reach effect, other symbols which are not arranged on the descending order side or the ascending order side for one symbol with respect to the first and third symbols 19 and 21 as the second symbol 20 are displayed, and the out-of-order state is confirmed.

Furthermore, when the determination result of step S10 is negative, that is, when it is determined that the reach state is not reached, the main CPU 26 determines the first to third symbols 19 to 21 from the numerical values of the respective outlier symbol random numbers extracted in step S9. Is determined (step S20, FIG. 5B). At this time, main C
When the first and third symbols 19 and 21 match, the PU 26 changes either one of the symbols so that the reach state is not formed.

Next, the main CPU 26 selects the table L6 for the outlying state from the plurality of types of tables L1 to L6 stored and held in the ROM 27 (step S21). Further, the main CPU 26 extracts the numerical value of the variation pattern allocation random number, and based on the numerical value, the table L
A variation pattern is selected from 6 (step S22). In this case, the variation pattern 1 is selected regardless of the numerical value.

Thereafter, the main CPU 26 outputs each command as a control signal to the design board 25 in the order of the fluctuation start command-> each design designation command-> all design designation command, in the same manner as described above. The symbol control is executed based on each command. And step S1
→ Step S2 → Step S9 → Step S10 → When the main CPU 26 outputs each command based on the flow of steps S20 to S22, the visible display portion H
Then, the out-of-state is established without the reach state being formed.

Next, the jackpot expectation (%) of each of the fluctuation patterns 1 to 5 in this embodiment will be described based on Tables 8 and 9. The "big hit expectation" is a measure of the ratio of occurrence of a big hit state (specific big hit state or normal big hit state) due to the appearance of the variation pattern, and the big hit state is as expected. Is not meant to occur. The higher the jackpot expectation value is (the closer it is to 100%), the more likely the jackpot state is to occur.

[0096]

[Table 9] Table 9 shows the number of revolutions (1 / R) until the variation patterns 1 to 5 appear, and the jackpot expectation degree (%) of each of the variation patterns 1 to 5. In addition, "the number of revolutions until the variation patterns 1 to 5 (1 / R)" means one rotation for one symbol combination game, and the variation pattern 1 with respect to the number of times (R) the game is played. .About.5 indicate the standard of the appearance rate once, and it does not mean that each variation pattern appears in accordance with this rotation speed. The smaller the numerical value (rotation number), the higher the rate of occurrence of the variation pattern. In the following description, a method of calculating the jackpot expectation degree (%) and the number of revolutions (1 / R) until the variation patterns 1 to 5 appear when a game is played with a probability of normal times will be described. .

First, a method of calculating the number of revolutions (1 / R) until the respective fluctuation patterns 1 to 5 appear will be described. First,
The number of rotations (1 / R) until the variation patterns 1 to 5 distributed to the tables L1 and L2 for the big hit state appear is
1 / ((big hit ratio) × (specific symbol to all symbols, or the ratio of non-specific symbols) × (variation pattern selection rate))
Can be calculated from

Specifically, in the case of the variation pattern 4 of the table L1, R = 1 / ((2 [big hit value number] / 631 [big hit determination random number]) × (5 [specific symbol number] / 10 [all] The number of symbols]) × (22/50)) = 1434.1. Therefore, the fluctuation pattern 4 of the table L1 appears once every 1434.1 rotations. In the case of the variation pattern 4 of the table L2, R = 1 / ((2/63
1) x (5 [number of non-specific symbols] / 10) x (12/5
0)) = 2629.2, and the fluctuation pattern 4 of the table L2 appears at a rate of once every 2629.2 rotations.

Further, the reach state tables L3, L
The number of rotations (1 / R) until the variation patterns 1 to 5 distributed to L4 and L5 appear is 1 / ((deviation ratio) ×
(Reach formation rate) x (Appearance rate of symbols) x
(Variation pattern selection rate)).

Specifically, in the case of the variation pattern 3 of the table L3, R = 1 / ((629 [excluding the jackpot value] / 6
31 [random number for jackpot judgment]) x (5 [number of reach judgment values]
/ 60 [random number for reach determination]) x (1 [number of symbols per frame] / 10 [total number of symbols]) x (15/50)) = 40
It becomes 1.3. Therefore, the variation pattern 3 of the table L3
Will occur once every 401.3 rotations.
In the case of the variation pattern 3 of the table L4, R = 1 /
((629/631) × (5/60) × (2 [number of symbols in one frame] / 10) × (15/50)) = 200.6. Therefore, the variation pattern 3 of the table L4 is 20
It will appear once every 0.6 rotations. In addition,
In the present embodiment, in step S11 (FIG. 6), when the second symbol 20 is the same symbol as the first and third symbols 19 and 21, the extracted value of the middle random symbol random number is +1.
Therefore, the number of symbols for +1 frame is “2”. Further, in the case of the variation pattern 3 of the table L5, R
= 1 / ((629/631) × (5/60) × (7 [other number of symbols] / 10) × (10/50)) = 85.9. Therefore, the variation pattern 3 of the table L5 is 85.9.
It will appear once per rotation.

Further, the number of rotations until the variation pattern 1 distributed to the out-of-range state table L6 appears (1 /
R) can be calculated from 1 / ((outage ratio) × (ratio in which reach is not formed)). Specifically, in the case of the variation pattern 1 of the table L6, R = 1 / ((62
9 [excluding jackpot value] / 631 [random number for jackpot determination])
X (55 [excluding reach determination value] / 60 [random number for reach determination]) = 1.1. Therefore, the variation pattern 1 of the table L6 appears once every 1.1 rotations.

The jackpot expectation (%) of each of the variation patterns 1 to 5 is the variation pattern 1 calculated as described above.
It can be calculated as follows from the number of revolutions (1 / R) until .about.5 appears. That is, jackpot expectation (%) =
((Addition value of the number of rotations until the variation pattern n distributed to the tables L1 and L2 for the big hit state appears) /
(Variation pattern n distributed to each table L1 to L6
Can be calculated by the following formula. In the present embodiment, “n” is 1, 2, 3, 4, and 5 because five types of variation patterns 1 to 5 are prepared.

Specifically, the jackpot expectation (%) of the variation pattern 1 is ((1/6310) / ((1/631
0) + (1 / 1.1))) × 100 = 0.017 (%)
Becomes In addition, expectation (%) of big hit of fluctuation pattern 2
Is (((1 / 2629.1) + (1/1752.
8)) / ((1 / 2629.1) + (1/1752.
8) + (1 / 182.4) + (1 / 91.2) + (1 /
21.5))) × 100 = 1.49 (%). Similarly, when the jackpot expectation rate (%) is calculated, the jackpot expectation degree of the variation pattern 3 is 4.74 (%), the jackpot expectation degree of the variation pattern 4 is 51.94 (%), and the variation pattern 5
The expectation of a big hit is 100 (%).

As described above, in the present embodiment, the variation pattern having a longer variation time (or the variation pattern having more transitions in the gaming state (reach state)) has a higher jackpot expectation and is more likely to cause the jackpot state. Has been done. That is,
As can be seen from Table 8, Table L for the big hit state
In 1 and L2, as compared with the other tables L3 to L6, the larger the variation pattern with a longer variation time (or the variation pattern with more transitions in the gaming state (reach state)), the greater the number of variation pattern distribution random numbers is assigned By dividing them, the jackpot expectation is set high. Therefore, the player has a big hit state (a particular big hit state or a normal big hit state or a normal big hit state) because a change pattern with a long change time (or a change pattern with a lot of changes in the game state (reach state)) appears on the visible display portion H. It is possible to increase the expectation that a big hit situation will occur. On the other hand, as can be seen from Table 9, the variation pattern having a longer variation time (or the variation pattern having more transitions in the gaming state (reach state)) is less likely to appear in the visible display portion H. Therefore, the player has a big hit state (a specific big hit state or a normal big hit state or a normal big hit state) when a change pattern with a long change time (or a change pattern with many changes in the game state (reach state)) appears on the visible display portion H. It is possible to further increase the expectation that a big hit situation will occur.

Therefore, according to this embodiment, the following effects can be obtained. (1) A variation pattern with a long variation time (or a variation pattern with a large number of transitions in a gaming state (reach state)) is configured to have a higher rate of occurrence of a specific jackpot state. Therefore, the player appears in the visible display portion H as a variation pattern having a long variation time (or a variation pattern in which the game state (reach state) changes a lot),
It is possible to increase the expectation that a specific jackpot state will occur. In addition, even if a variation pattern with a long variation time (or a variation pattern with a lot of transitions in the game state (reach state)) appears, the player sees the production to the end without losing interest in the production content. You can

(2) When a specific big hit state is generated, the main CPU 26 has a high selection rate for selecting a variation pattern having a long variation time (or a variation pattern in which the gaming state (reach state) changes a lot). It is set. Therefore, the main CPU 26 can select a variation pattern with a long variation time (or a variation pattern with a large transition of the gaming state (reach state)) at a high rate when a specific big hit state occurs.

(3) When the normal big hit state occurs, the main CPU 26 has a low selection rate for selecting a variation pattern having a long variation time (or a variation pattern in which the gaming state (reach state) changes a lot). It is set. Therefore, the main CPU 26 can select a variation pattern with a short variation time (or a variation pattern with a small transition of the gaming state (reach state)) when a normal big hit state occurs. Therefore, it is possible to clearly distinguish between the case where a specific big hit state is generated and the case where a normal big hit state is generated, and the player can change patterns (or game states (reach state) with a long change time). ), There are many transition patterns), and it can be expected that a specific big hit state will occur.

(4) Reach state tables L3 and L4
Then, the first, the third symbol 1 which forms the reach state, as the variation pattern (or the variation pattern in which the gaming state (reach state) changes more often) has a longer variation time than the table L5.
The symbols arranged on the ascending order side or the descending order side for one symbol with respect to 9, 21 are more likely to be displayed as the second symbol 20. Therefore, the player is displayed as the second symbol 20 even if the out-of-position state is formed as a result of the effect by the variation pattern having a long variation time (or the variation pattern in which the transition of the gaming state (reach state) is large). You can get a feeling that it was a shame to see the types of designs.

(5) Reach state tables L3 to L5
Then, it is configured such that a variation pattern with a shorter variation time (or a variation pattern with less transition of the game state) has a higher selection rate of the main CPU 26. Therefore, as a result of the reach effect, when an out-of-range state is formed (out-of-range reach), by lowering the rate of appearance of a variation pattern with a long variation time, the game time is shortened and the player's game It is possible to suppress the risk of losing interest.

(6) A variation pattern with a longer variation time (or a variation pattern with more changes in the gaming state (reach state)) has a higher jackpot expectation and is more likely to cause a jackpot state. Therefore, the player has a big hit state (a particular big hit state or a normal big hit state or a normal big hit state) because a change pattern with a long change time (or a change pattern with a lot of changes in the game state (reach state)) appears on the visible display portion H. It is possible to increase the expectation that a big hit situation will occur. In addition, a variation pattern having a longer variation time (or a variation pattern in which the game state (reach state) has more transitions) is less likely to appear in the visible display portion H. Therefore, the player has a fluctuation pattern with a long fluctuation time (or a fluctuation pattern with many changes in the game state (reach state)),
By appearing in the visible display portion H, it is possible to further enhance the expectation that a big hit state (a specific big hit state or a normal big hit state) will occur.

The above embodiment may be modified as follows. The configuration of the variation patterns 1 to 5 in the above embodiment can be changed as appropriate. That is, the fluctuation times T1 to T5 of the fluctuation patterns 1 to 5 do not necessarily have to be different as in the above embodiment. For example, as shown in FIG. 4B, the fluctuation patterns 3 to 5 may be set to the same fluctuation time T6, and the number of game states changing (number of operations) may be different. Specifically, the variation pattern 3 is from the three stages of action A → action B1 → action C1, and variation pattern 4 is action A.
The movement pattern 5 is composed of five stages of: action B1, action C2, action D1, and action pattern A, action B2, action C3, action D2, action E. In this case, the variation pattern 5 has a large number of transitions of the game state, and the variation pattern 1 → variation pattern 2 → variation pattern 3 as in the above embodiment.
→ The variation pattern 4 → the variation pattern 5 may be increased in the order of occurrence of the specific jackpot state (or the rate of display of the specific symbol).

In the above embodiment, the variation pattern may be configured by adding the operation associated with the re-lottery. The "re-lottery" is an effect in which the player is given an expectation that the mode of the combination of the non-specific symbols develops into the mode of the combination of the specific symbols to improve the game effect.

In the above-mentioned embodiment, the case where the variation time from the start of variable display to the fixed display of symbols is long or the transition of the game state is large is taken as an example, but the game state in the reach state is changed. The variation pattern with a large number of changes or the variation pattern with a long variation time may increase the rate at which a particular big hit state occurs (or the rate at which a specific symbol is displayed). In addition, paying attention only to the movement of the symbol at the time of the re-lottery, for example, when the number of times of the re-lottery is large or when the fluctuation time at the time of the re-lottery is long, the ratio of the specific jackpot state (or the specific symbol is The displayed ratio) may be increased.

In the above-described embodiment, the pachinko machine 10 having the probability variation function is applied, but the present invention can be similarly applied to a pachinko machine having a time shortening function (so-called time saving machine). In this case, the symbols can be classified according to whether the number of times saved is large or small, and the longer the fluctuation pattern (or the fluctuation pattern in which the gaming state (reach state) changes more) is, the more times saved. It suffices to configure the display ratio of the symbols to be high.

In the above-mentioned embodiment, out of all 10 types,
Five types are specified for each of the specific symbol and the non-specific symbol (the apparent probability change rate is ½), but the ratio of the specific symbol and the non-specific symbol may be changed as appropriate, and this percentage is the pachinko machine 10
It is decided based on the design specifications of. Further, the classification of symbols is not limited to two types such as a specific symbol and a non-specific symbol. For example, in the case of a time saving machine, the case where the number of times saving is 100 times / 50 times / 0 times and the like can be divided into three types can be applied similarly to the above embodiment.

In the above embodiment, the five types of fluctuation patterns 1 to 5 are distributed to the six types of tables L1 to L6, but the number of fluctuation patterns and the number of tables are not limited to those in the above embodiments. Further, the number of numerical values of the variation pattern distribution random number is not limited to the above embodiment.

The above embodiment can be similarly applied to a symbol display device other than the symbol display device 18 provided with the visible display portion H formed of a liquid crystal screen. For example, it can be similarly applied to a pattern display device such as a 7-segment LED type, a dot matrix type, or a mechanical type (drum type or belt type). Further, the present invention is not limited to the symbol display device capable of displaying the symbols in the three columns, and can be similarly applied to the symbol display device capable of displaying the symbols in the first column, the second column, the fourth column, and the fifth column. In the symbol display device capable of displaying one row of symbols, a specific big hit state or a normal big hit state is formed depending on the type of the displayed symbols. On the other hand, in the symbol display device capable of displaying symbols in a plurality of columns such as three columns as in the present embodiment, the big hit state is formed from the combination mode of the displayed symbols and the combination mode is configured. Depending on the type of pattern to be performed, a particular big hit state or a normal big hit state occurs.
