Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a pachinko machine, and more particularly, to a gaming machine in which the probability of occurrence of a special gaming state advantageous to a player is changed.

[0002]

2. Description of the Related Art Conventionally, as one form of a pachinko machine, there is known a pachinko machine having a function of changing the occurrence probability of a jackpot game state advantageous to a player according to conditions, a so-called probability changing function. In this pachinko machine, when the game situation that changes according to the operation of the player satisfies a predetermined condition, for example, when the game ball wins the starting port, the symbol change on the display device is started. If the symbol combination displayed on the display device after the symbol change is stopped after the reach gaming state is a predetermined jackpot combination, the jackpot gaming state is generated based on the combination. Furthermore, if the symbol displayed on the display device after the symbol change is stopped is a symbol of a predetermined type, the probability of occurrence of the next big hit gaming state is increased.

[0003]

However, in the above-described conventional pachinko machine, when the game situation reaches the reach game state, the player can know whether or not the probability fluctuation has occurred.
This means that the presence or absence of probability fluctuation is determined according to the type of symbol displayed at the time of occurrence of the big hit gaming state, and that the same type of symbol is already displayed at the time of occurrence of the reach gaming state by. This point is a relatively early point in the period from the start of the symbol change on the display device to the occurrence of the big hit game state. That is, in the above period,
When a little less than 10 seconds elapse from the start of the symbol change, the reach game state occurs, and the symbol change in the two symbol rows is stopped. Then, the reach gaming state ends at the point when a maximum of less than 30 seconds has elapsed from the start of the symbol change, and the symbols that have changed to the end are stopped. At the point before 10 seconds elapses in such a period of less than 30 seconds, it is determined whether or not the probability fluctuation occurs due to the occurrence of the reach game state.
For this reason, even if the pachinko machine has a probability variation function,
There is a problem in that the sense of expectation for the occurrence is reduced from an early stage, and the interest of the game is spoiled.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and a problem to be solved is to maintain a player's expectation of occurrence of a probability change after the start of a symbol change until late. Is to provide a gaming machine capable of fully enjoying or expecting an effect by a reach action or the like during a reach gaming state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment embodying the first and second inventions will be described below with reference to FIGS.
1 will be described.

As shown in FIG. 1, a game board 1 of a pachinko machine as a game machine has a first type start port 2, a special symbol display device (hereinafter simply referred to as "display device") 3, and a special winning opening 4. Is provided. The first-type starting port 2 has a passage for the game ball 5, and the entrance of the passage supports blades 2a and 2b so as to be openable and closable.

The display device 3 is provided above the first type start-up port 2 and has a screen 3a composed of a liquid crystal display (LCD). Other types of images are displayed on the screen 3a, one of which is a character display area Z1 and a symbol row display area Z2. A plurality of characters are displayed in a character display area Z1, and a left symbol row 7, a middle symbol row 8, and a right symbol row 9 are displayed in a symbol row display area Z2.
Is displayed. The number of symbol rows is not limited to the above (three rows), but may be one row, two rows, four rows or more. As shown in FIG. 10A, each of the symbol rows 7 to 9 is composed of a plurality of types of symbols 11 including numbers, symbols, and the like.

As shown in FIG. 1, in the display device 3, the symbol variation in the symbol rows 7 to 9 is caused by the first type starting port 2 of the game ball 5.
Start by winning a prize. The symbol change is stopped in the order of the left symbol row 7, the right symbol row 9, and the middle symbol row 8, but this is only an example and may be stopped in another order. When the symbol variation in all the symbol columns 7 to 9 is stopped, the combination of the displayed symbols 11 is a predetermined combination (specific display result, hereinafter referred to as “big hit combination”), that is, the same type. The combination of the symbols 11 when the symbols 11 are arranged along the big hit line (for example, 777) may be obtained. This combination of the symbols 11 is hereinafter referred to as a “big hit symbol”. In the present embodiment, there are a total of five types of big hit lines, one that extends in the horizontal direction (three types of upper, middle, and lower) and one that extends diagonally (two types of downward and right descending). Not limited to For example, the number of big hit lines is one, and it may be what is usually called “one line”.

When the combination of the big hits is established as described above, the special electric accessory is activated, and the big hitting game state as a special game state advantageous to the player arrives, so that more prize balls can be obtained. It becomes possible.

Further, the pachinko machine enters the reach game state prior to the occurrence of the big hit game state. Here, the reach game state refers to a state immediately before the big hit game state, for example,
The symbol fluctuation in the right symbol row 9 stops on the big hit line at the symbol 11 of the same type as the stop symbol in the left symbol row 7,
In addition, if the symbol fluctuation in the middle symbol row 8 is subsequently stopped in the same type of symbol 11 as the stopped symbols in the left and right symbol rows 7 and 9, a state in which a big hit combination is finally included. In addition, when the symbol change stops, the combination changes to a big hit game state, and when the symbol 11 is stopped, the big hit game state is finally reached, and the changing state is also included in the reach game state. This is what is usually called full rotation (all symbols) reach.

In the reach game state, each of the aforementioned symbol rows 7
In addition to the pattern fluctuations in the steps 9 to 9, a state in which a plurality of types of characters move according to a plurality of reach actions (reach patterns) is displayed on the screen 3a. In the present embodiment, as shown in FIG. 11D, dragon 12, Michael 13, Doctor X (X) 14, Lily 15, and Yokozuna 16 are set as characters. As a reach pattern, "normal reach", "super reach", and "special reach" are set for each character.
The expected value for the occurrence of the big hit gaming state is set to be higher toward the rear in the above-described three types of reach patterns. Further, the above-described “full rotation reach” is also included in the reach pattern. In the full rotation reach, unlike the above three types of reach, all the characters are simultaneously displayed as shown in FIG.

As shown in FIG. 1, the special winning opening 4 is provided below the first-type starting opening 2, and one V zone 17,
Two passages 18 and 19 and a shutter 21 are provided.
The shutter 21 is operated by a special winning opening solenoid (hereinafter, simply referred to as a solenoid) 22,
And the entrances of the passages 18 and 19 are opened and closed.

In order to detect a game situation that changes according to the operation of the player, a switch 2 for a starting port is provided on the game board 1.
3. V zone switch 24 and count switch 25
Is installed. The starting port switch 23 corresponds to a game situation detecting means, and detects a winning of the gaming ball 5 into the first type starting port 2. The V zone switch 24 detects the winning of the gaming ball 5 in the V zone 17, and the count switch 25 detects the winning of the gaming ball 5 in the large winning opening 4.
Further, a control device 26 is provided to drive and control the solenoid 22 and the display device 3 based on the detection results of the switches 23 to 25. The control device 26 includes a read-only memory (ROM), a central processing unit (CPU), a random access memory (RAM), and the like. The ROM stores a predetermined control program and initial data in advance,
The CPU executes various arithmetic processes according to a control program of the ROM and the like. The RAM temporarily stores the calculation result by the CPU.

As one of the controls by the CPU, there is a so-called probability variation in which the occurrence probability of the big hit game state is varied according to conditions. Specifically, a low-probability mode in which a large-hit game state is generated with a low probability of about 1/300 and a high-probability mode in which a large-hit game state is generated with a high probability of about 1/60, which is about five times as large, are prepared. The probability mode is switched according to the type of the character displayed during the reach game state. In the present embodiment, the dragon 12 and the Yokozuna 16 that are displayed independently and all the characters that are displayed simultaneously are set as the characters when switching from the low probability mode to the high probability mode. Other characters displayed alone are set as low probability mode characters. Note that the multiple of the occurrence probability in the high probability mode with respect to the occurrence probability in the low probability mode may be a value other than the value (about 5) described above.

Next, the operation and effects of the pachinko machine configured as described above will be described. 2 to 9 show various routines executed by the control device 26. Each process of these routines is executed based on the counter group and the flag F.

The counter group includes a round counter R for counting the number of rounds, and a count switch 25.
And a winning counter C for counting the number of winning of the game balls 5 to the special winning opening 4 based on the detection result of the game. In addition, the counter group includes an internal random number counter for determining the occurrence of a jackpot game state, an off-reach random number counter for determining an off-reach, and the like, and a display when each of the symbol rows 7 to 9 stops the symbol change. Symbol counters for determining symbols to be performed (hereinafter referred to as stopped symbols), etc., a reach type counter for determining the type of reach operation, and a character type counter for determining the type of character. . Here, the off-reach by the off-reach random number counter refers to a state in which a big hit combination is not finally formed after the above-mentioned reach game state. The flag F is for determining the presence or absence of a prize of the game ball 5 in the V zone 17, and is set to "0" when no prize is detected by the V zone switch 24, and when a prize is detected. Set to “1”. It has been described that there are two types of probability modes, a low probability mode and a high probability mode, but the low probability mode is set as the initial value.

When the game is started by the player, the control device 26 first determines the first position of the game ball 5 based on the detection result of the starting port switch 23 in step S10 of the special electric accessory control routine of FIG. It is determined whether or not there is a prize in the seed starting port 2. If this determination condition is not satisfied, the special electric accessory control routine ends, and if it is satisfied, in step S20, the values of the internal random number counter and the out-of-reach random number counter are obtained, and the value of each symbol counter is Based on each of the symbol rows 7 to 9, a symbol is obtained. The acquisition here refers to a process of reading the value of each counter and storing the value in a memory.

Next, a symbol variation start process is executed in step S30. Specifically, in step S31 of FIG. 4, each symbol 11 of the symbol rows 7 to 9 is displayed on the display device 3 respectively.
To change the display. With this display, the player sees the three reels of left, center, and right as if they are rotating. In step S32, it is determined whether or not the value of the internal random number counter is equal to the big hit value. As the jackpot value, two types of values (a jackpot value for low probability and a jackpot value for high probability) are prepared. The former is a value for generating the jackpot gaming state with a low probability as described above, and the latter is a value for generating the jackpot gaming state with a high probability. For example, the internal random number counter updates the value every predetermined time within a range of “0” to “299”, and “7” of the counter is set as the jackpot value for low probability and “7”, “17”, "27", "37", "4
7 "is set as the jackpot value for high probability. Then, the probability of occurrence of the jackpot gaming state becomes 1/300 when the low probability jackpot value is used as the big hit value, and becomes 1/60 when the high probability jackpot value is used as the big hit value. When the low probability mode is set in the previous control cycle, the low probability big hit value is selected as the big hit value. If the high probability mode is set, the high probability jackpot value is selected as the jackpot value.

If the determination condition in step S32 is satisfied, in step S33, the big hit symbol corresponding to the big hit value is stored in the memory as a stop symbol.
Move to 37. On the other hand, if the determination condition in step S32 is not satisfied, in step S34, it is determined whether the value of the out-of-reach random number counter is the same as a predetermined out-of-reach value. If this determination condition is satisfied, in step S35, the symbol corresponding to the outreach value (hereinafter, referred to as outreach symbol) is stored in the memory as a stop symbol, and the process proceeds to step S37. If the determination condition in step S34 is not satisfied, in step S36, the symbol lost in step S20 is stored in the memory as a stop symbol, and the symbol variation start processing routine ends.

In step S37 after step S33 or S35, a reach pattern and a character are acquired. Specifically, the value of the reach type counter is read, and the type of the reach pattern is determined based on the value. Further, the value of the character type counter is read, and the type of the character is determined based on the value. Subsequently, in step S38, it is determined whether or not the character acquired in step S37 is the same as a predetermined specific character. If this determination condition is satisfied, the high probability mode is set in step S39, and if not, the low probability mode is set in step S40. After setting the probability mode in step S39 or S40, the symbol variation start processing routine ends.

After executing the processing of step 30 (symbol change start processing) as described above, in step S50, the symbols 11 in the left and right symbol rows 7 and 9 are replaced with the symbols of step S
The stop symbol stored in any of the processes of 33, S35, and S36 is replaced. The symbol change in the left and right symbol rows 7 and 9 is stopped by the symbol 11 after the replacement.

Next, a reach operation process is performed in step S60. Specifically, in step S61 of FIG. 5, it is determined whether or not the reach pattern acquired in step S37 is a dragon normal reach. If this determination condition is not satisfied, the dragon normal reach operation process is performed in step S62. This routine includes the processes of steps S62A to S62C as shown in FIG. Step S6
In 2A, the background color of the symbol row display area Z2 is changed to a different color from the background color. In step S62B, FIG.
As shown in (a), the spotlight 27 is displayed on the reach line (big hit line). In step S62C, the symbols 11 located on the reach line in both the left and right symbol rows 7 and 9 are displayed brighter than before.

If the determination condition of the step S61 is satisfied, that is, if it is not the dragon normal reach, in a step S63, it is determined whether or not the reach pattern is the dragon super reach. If this determination condition is not satisfied, the dragon super reach operation processing is performed in step S64. This routine includes the processing of steps S64A to S64E and S64G, as shown by the solid line in FIG. Steps S64A to S64C are the same as steps S62A to 62C described above. In step S64D, as shown in FIG.
Raises his hand and displays an operation of radially emitting a plurality of plasmas 28. In step S64E, FIG.
As shown in FIG. 7, a part of the dragon 12 is instantaneously enlarged and displayed in the character display area Z1. In step S64G, FIG.
As shown in 0 (e), the operation in which the dragon 12 hits the button 6 vigorously to stop the symbol change in the middle symbol row 8 is displayed.

If the determination condition in step S63 is satisfied, that is, if it is not the dragon super reach, it is determined in step S65 whether the reach pattern is not the dragon special reach. If this determination condition is not satisfied, dragon special reach operation processing is performed in step S66. This routine includes steps S66A to S66G as shown in FIG. Step S66
The processes from A to S66E are performed in step S64A described above.
To S64E. In step S66F, the background color of the symbol row display area Z2 is switched to a light color.
As shown in (d), dragon 12 is behind dragon 2
9 is displayed. In a succeeding step S66G, the same process as that in the step S64G is performed. That is, the dragon special reach is different from the dragon super reach in that the process of step S66F is added.

As described above, when the character acquired in the step S37 is the dragon 12, one of the dragon normal reach, the dragon super reach, and the dragon special reach is selected, and the reach game is performed according to a predetermined procedure. The state is advanced.

If the determination condition in step S65 is satisfied, it is determined in step S67 whether the reach pattern is not Yokozuna normal reach. If this determination condition is not satisfied, the normal reach operation process of Yokozuna is performed in step S68. This routine includes steps S68A to S68C as shown in FIG. In step S68A, the background color of the symbol row display area Z2 is changed to a different color from the background color. Step S
In 68B, as shown in FIG. 11A, an image obtained by irradiating the spotlight 31 on the reach line is displayed. In step S68C, the symbols 11 located on the reach line in both the left and right symbol rows 7 and 9 are displayed brighter than before. That is, in the Yokozuna normal reach, a display similar to that of the dragon normal reach is made, except that the displayed character is switched from Tatsu 2 to Yokozuna 16.

If the determination condition of the step S67 in FIG. 5 is satisfied, that is, if it is not the Yokozuna normal reach, in a step S69, it is determined whether or not the reach pattern is the Yokozuna super reach. If this determination condition is not satisfied, a Yokozuna super-reach operation process is performed in step S70. This routine includes the processing of steps S70A to S70D as shown by the solid line in FIG. The processes in steps S70A to S70C are the same as those in steps S68A to 68C described above. In the subsequent step S70D, an action in which the yokozuna 16 alternately stretches with one hand as shown in FIG. 11B is displayed in synchronization with the symbol change in the middle symbol row 8.

If the judgment condition of the step S69 in FIG. 5 is satisfied, that is, if it is not the Yokozuna super reach, it is judged in a step S71 whether or not the reach pattern is the Yokozuna special reach. If this determination condition is not satisfied, Yokozuna special reach operation processing is performed in step S72. This routine includes the processes of steps S72A to S72F as shown in FIG.
The processes in steps S72A to S72D are the same as those in steps S70A to S70D described above. In a succeeding step S72E, as shown in FIG.
Displays the action of clasping with both hands in synchronization with the symbol change in the middle symbol row 8. In step S72F, the state in which the middle symbol row 8 broken by the claws collapses and the operation in which the symbol 11 fluctuates are displayed in synchronization.

As described above, when the character acquired in the step S37 is the Yokozuna 16, one of the Yokozuna Normal Reach, the Yokozuna Super Reach, and the Yokozuna Special Reach is selected, and the reach game state is set according to a predetermined procedure. Is advanced.

If the determination condition in step S71 is satisfied and the character obtained in step S37 is any one of Michael 13, Lily 15, and doctor X14, the above-mentioned dragon 12 and Yokozuna 16 are used. Is performed. Here, illustration and description of the contents of each process are omitted.

If the character is not a reach pattern by any character, in step S73,
It is determined whether the reach pattern is not full rotation reach. If this determination condition is not satisfied, step S7
In step 4, a full rotation reach operation process is performed. For details, see FIG.
As shown in (d), all the characters appear in the character display area Z1 while changing the symbols 11 in all the symbol rows 7 to 9. Further, a state in which the symbol 11 repeatedly performs the change state and the stop state is displayed. The fluctuating state here is a state where each of the symbols 11 of the symbol rows 7 to 9 fluctuates at a high speed, and the stop state is a state where the combination of the symbols 11 is kept constant and the symbol 11 fluctuates at a low speed. is there.

When the determination condition of step S73 is satisfied, and when the above-described steps S62, S64, S6
If any of the processes in S6, S68, S70, S72, and S74 has been executed, the reach operation process routine ends, and the process proceeds to step S80 in FIG.

In step S80, the symbol fluctuation in the middle symbol row 8 is stopped. Subsequently, in step S90,
It is determined whether or not the combination of the symbols 11 is a big hit combination. If this determination condition is not satisfied, the special electric accessory control routine is terminated.
At 100, the round counter R is reset. In step S110, the winning counter C is reset, and the flag F is set to "0".

Subsequently, in step S120 of FIG. 3, the solenoid 22 is excited. Then, the shutter 21 falls down to a substantially horizontal state, and the passage entrance of the special winning opening 4 is opened. With this opening, it is possible to win a prize in the V zone 17 and the passages 18 and 19 of the game ball 5. Step S130
Increments the round counter R by "1".

Next, in step S140, it is determined whether or not the value of the winning counter C is equal to or less than a predetermined value Cmax. If this determination condition is satisfied, step S15
At 0, it is determined whether or not the scheduled closing time of the special winning opening 4 is yet. If this determination condition is satisfied, the process returns to step S140. As a result, the special winning opening 4 is kept open unless more than Cmax game balls 5 win or the scheduled closing time comes after the opening of the special winning opening 4. On the other hand, if one of the determination conditions in steps S140 and S150 is not satisfied, the solenoid 22 is demagnetized in step S160. Then
The shutter 21 is raised to be substantially vertical, and the special winning opening 4
Passage entrance is closed.

In step S170, it is determined whether the value of the round counter R is equal to or less than a predetermined value Rmax. If this determination condition is satisfied, then step S18 is performed.
At 0, it is determined whether or not the flag F is “1”.
If the determination condition of step S180 is satisfied, the process returns to step S110. Therefore, once the big hitting game state occurs, the big winning opening 4 repeats a cycle of opening and closing until the game ball 5 wins a maximum Rmax times in the V zone 17. For example, if the predetermined value Cmax is set to “10”, the opening time of the special winning opening 4 is set to “about 29.5” seconds, and the predetermined value Rmax is set to “16”, After the opening of the mouth 4, when either one of the following conditions is satisfied: (1) ten game balls 5 win in the big winning opening 4, and (2) approximately 29.5 seconds elapse. The winning opening 4 is closed. The opening and closing cycle of the special winning opening 4 is a game ball 5
Is repeated up to 16 times on condition that the player wins the V zone 17. If either one of the determination conditions in steps S170 and S180 is not satisfied, the special electric accessory control routine ends.

In the present embodiment, the steps S10, S30, S50, S60,
The processing in S80 corresponds to the display control means, and the processing in step S9
The processing of 0, S120 corresponds to a special game state generating means. Step S3 in the symbol variation start processing routine
Steps S8, S39, and S40 correspond to the probability varying means, and correspond to steps S62, S6 in the reach operation processing routine.
The processing of 4, S66, S68, S70, S72, S74 corresponds to the character display means.

As described above, the probability of occurrence of the next big hit gaming state, that is, the probability that the value of the internal random number counter becomes equal to the big hit value in step S32 of the symbol variation start processing routine is set in steps S39 and S40. It varies depending on the type of probability mode (high probability mode or low probability mode). Then, the probability mode is determined according to the type of the character acquired in step S37. The character is actually displayed on the display device 3 after the occurrence of the reach game state, that is, after the symbol fluctuation stops in the left and right symbol columns 7 and 9.

Therefore, at the time when the symbol fluctuation in both the left and right symbol columns 7 and 9 stops, it is unknown to the player whether or not the probability fluctuation occurs. Thereafter, at the point in time when the game situation progresses according to a specific background, that is, at the point in time when the reach operation by any of the characters is started by the processing of the reach operation processing routine, the presence / absence of the probability change becomes clear. In the present embodiment, when the dragon 12 or the yokozuna 16 is displayed alone, or when all the characters are displayed at the same time, it is clear that the next occurrence probability is increased, and when the other characters are displayed. It becomes clear that the probability of occurrence remains low.

As described above, according to the present embodiment, the point in time at which the presence or absence of the occurrence of the probability fluctuation is clarified is later than in the prior art. Therefore, when the player has an expectation that a probability variation may occur due to the start of the symbol variation, the expectation is changed to the left and right symbol columns 7,
Even after the symbol change in 9 has stopped, it can be held continuously. Unlike the prior art, it is possible to prevent the expectation of occurrence of the probability fluctuation from fading from an early stage, thereby preventing the interest of the game from being spoiled.

The processing procedure in this embodiment is an example, and can be changed as appropriate. For example, the symbol variation start process (step S31) is stopped, and the symbol storage process (step S31) is stopped.
33, S35, S36). The setting process of the probability mode (steps S39 and S40) may be performed in the reach operation process routine.

(Second Embodiment) Next, a second embodiment embodying the first and third inventions will be described. In the second embodiment, the probability mode is switched according to the type of the reach pattern displayed during the reach game state instead of the type of the character in the first embodiment, and the occurrence probability is changed. As a reach pattern when switching from the low-probability mode to the high-probability mode, a special reach and a full rotation reach for each character are set. Normal reach and super reach are set as the reach patterns for the low probability mode. Other items, for example, the mechanical configuration of the pachinko machine are the same as those of the first embodiment, and the description thereof is omitted here.

As shown in part A of FIG.
When the reach pattern and the character are acquired in step S37 of the symbol variation start processing routine, the process proceeds to step S4.
In 1, it is determined whether the reach pattern is the same as a predetermined specific reach pattern. If this determination condition is satisfied, the high probability mode is set in step S39, and if not, step S40
To set the low probability mode. After executing the processing of steps S39 and S40, this routine ends.

In the present embodiment, the processing of steps S41, S39, and S40 in the symbol change start processing routine corresponds to a probability changing means. Steps S62, S64, S66, S68, S in the reach operation processing routine
The processing of 70, S72, and S74 corresponds to reach operation display means.

For this reason, according to the second embodiment, in addition to the operation and effect of the above-described first embodiment, the probability mode that determines the probability of occurrence of the next big hit game state is determined in step S
It is determined according to the type of the reach pattern acquired at 37. The reach pattern is actually displayed on the display device 3 at the time of the occurrence of the reach game state, that is, after the symbol fluctuation stops in the left and right symbol rows 7 and 9.

Therefore, the left and right symbol rows 7, 9 are provided to the player.
It is not known at the time when the symbol change in the above has stopped that the probability change has occurred. Thereafter, when the game situation progresses according to a specific background, that is, when the reach operation processing routine proceeds and one of the reach patterns is started, the presence or absence of the probability fluctuation becomes clear. Here, at the time when "special reach" using any of the characters or "full rotation reach" using all the characters is displayed, if the big hit game state occurs, the probability of the next occurrence is increased. It becomes clear that the occurrence probability remains low when other reach is displayed. Also, in the pachinko machine which becomes the big hit game state after the reach game state by full rotation reach,
When the full rotation reach is displayed, it becomes clear that the probability of occurrence of the next big hit gaming state is increased. As described above, according to the present embodiment as well, the point in time at which it is clear whether or not the probability fluctuation has occurred becomes later than in the related art. For this reason, it is possible to make the player have a sense of expectation for the occurrence of the probability fluctuation until late and keep the interest of the game high.

Here, the reach patterns for increasing the probability of occurrence include “normal reach”, “super reach”,
Either “special reach” or “full rotation reach” may be selected, but at the point in time when it is clear whether or not probability fluctuation has occurred, “super reach” is slower than “normal reach” and “super reach” "Special reach" is slower than "reach". This is for the following reason.

The processing content of "super reach" is roughly divided into a first half and a second half. In the first half, the same processing as in "normal reach" is performed, and in the second half, a different processing is performed.
For example, in the case of “Shin Super Reach”, the processes of steps S64A, S64B, and S64C are performed in the first half, and the processes of steps S64D, S64E, and S64G are performed in the second half. In “special reach”, the same processing as “super reach” is performed in the first half, and different processing is performed in the second half. For example, "Tatsun Special Reach"
In the case of, the same processing as “Tatsun super reach” is performed, and steps S66A, S66B, S66C, S66D,
E and S66G are performed, and as a different process, step S66E is performed between step S66E and step S66G.
66F is performed.

Therefore, after the occurrence of the reach game state, when all the processes of “normal reach” are performed, whether the reach pattern is “normal reach” or another type (super reach, special reach) is determined. It becomes clear for the first time. After that, the process of "Super Reach" is performed, and at the final stage, when the scheduled time of processing of the characteristic part of "Special Reach" has elapsed, whether the reach pattern is "Super Reach" or "Special Reach" It becomes clear that there is.

For this reason, if “normal reach” is set as a reach pattern that increases the probability of occurrence, the presence or absence of a probability change becomes clear at a relatively early stage after the occurrence of the reach game state. If "Super Reach" or "Special Reach" is set, it will not be clear whether or not a probability change has occurred unless a later time than in the case of "Normal Reach". In the present embodiment, since “special reach” is set, the point in time at which it is clear whether or not the probability fluctuation has occurred can be effectively delayed. Accordingly, the player can sufficiently enjoy the effect by the reach action or the like in the reach game state, which is performed for a maximum of nearly 20 seconds.

The present invention can be embodied in another embodiment described below.

(1) The first embodiment and the second embodiment may be combined. In this case, as shown in part A of FIG.
Between the step S38 and the step S39 of the symbol variation start processing routine in the first embodiment and the step S38 in the second embodiment between the step S38 and the step S40.
41 is added. In other words, only when the character obtained in step S37 is the same as the specific character and the reach pattern obtained in step S37 is the same as the specific reach pattern,
At 39, the high probability mode is set. Otherwise, i.e., if the acquired character does not match the specific character, or if it matches but the acquired reach pattern does not match the specific reach pattern, set the low probability mode I do. This way,
The point in time at which the presence or absence of the probability fluctuation has become clear can be further delayed.

(2) In the first embodiment, the type of the character to be displayed in the reach game state may be notified in advance before or during the change of the symbol 11. Similarly, in the second embodiment, the type of the reach pattern to be displayed in the reach game state may be notified in advance. In the latter case, for example, a preliminary announcement that at least super-reach will be made is performed. Then, it will always evolve from normal reach and become a super reach, but it is not known whether it will evolve further and become a special reach. Therefore, it is possible to enjoy or expect the process of becoming a reach pattern (special reach) causing a probability change.

(3) In the first embodiment, the displayed character may be replaced with another type of character immediately before the symbol change in the middle symbol row 8 stops. In this way, it is not known whether or not the probability fluctuation has occurred until just before the end of the reach game state, and it is possible to keep the expectation of the occurrence until the latest. For example, a character that does not cause a probability change to a high probability is displayed,
Immediately before the occurrence of the jackpot gaming state, the character is replaced with another character.

(4) The number of reach patterns may be varied according to the type of character.

(5) The history of the reach game state may be reported. The means for notifying is not limited to the display on the display device 3, but may be a display at another place, a sound from a speaker, or the like. The display at other places includes lighting or blinking by a lamp. In this way, even if the player misses the character or the reach pattern related to the probability variation during the reach game state and looks at the display device 3 at the time of the combination of the big hit symbols, It is possible to know whether or not the reach gaming state having such contents has been performed and whether or not probability fluctuation occurs. For example, if the dragon 29 described in FIG. 10D is displayed only for about one second, it may be overlooked. But dragon 29
Is displayed, even after the dragon 29 is missed, the occurrence of the probability fluctuation based on the dragon special reach can be known.

When displaying the history, for example, FIG.
As shown by a two-dot chain line in (b), a history display area Z3 is provided in a part of the symbol row display area Z2. This area Z3
In addition, the type of reach pattern (for example, “special reach”), the history of the reached reach pattern (for example, “normal reach → super reach”), “chance”,
"Probability variation" is displayed. In this case, the history display area Z
The display position of No. 3 is not particularly limited, but is preferably a position on the reach line that does not interfere with the design. Further, as another mode of the history display, at least a part of the color of the image may be changed when the process of causing the probability fluctuation is traced.

(6) The history display area Z3 in the above (5) may be continuously displayed even during the big hit game state, so that the history can be understood even in the state.

(7) The expected value for the occurrence of the probability variation may be changed depending on the type of the symbol 11 whose variation stops when the reach game state occurs. For example, if the symbol change stops at the symbol 11 with the number “7”, a character highly relevant to the probability change may be displayed with a high probability.

(8) The third invention can be applied to a gaming machine in which a reach gaming state is advanced without using a character.

(9) The present invention can be applied to a pachinko machine of a type different from the above-described embodiment, for example, a pachinko game machine with a third type start port. In addition to the pachinko machine, the present invention can be applied to a gaming machine having a display device such as an arepachi and an arrangement ball.

(10) Although the reach is displayed in a stepwise manner in both embodiments, the present invention is not limited to this. For example, the contents of the normal reach, the super reach, and the special reach may be completely different from each other. In the case of Tatsun, the content may be such that plasma is emitted in super reach and flame is emitted in special reach.

(11) The present invention can be applied not only to the next time, but also to a gaming machine of a type in which the probability of occurrence of at least one big hit game state after the next time is changed.

[0070]

As described above, according to the first aspect of the present invention, the expectation of the occurrence of the probability fluctuation, which the player has after the start of the symbol fluctuation, can be maintained until late.

According to the second aspect, in addition to the effect of the first aspect, the expectation can be maintained until the specific character is displayed after the occurrence of the reach game state.
For this reason, the player can fully enjoy or expect the effect by the reach action or the like during the reach game state.

According to the third aspect, in addition to the effects of the first or second aspect, the expectation can be maintained until a specific reach operation is displayed after the occurrence of the reach game state.
