DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine, arepachi, arrangement ball, throttle machine, and the like, and more specifically, a symbol row fluctuated and displayed on a symbol display is stopped at a predetermined special symbol. The present invention relates to a gaming machine that generates a special gaming state advantageous to a player based on the above.

[0002]

2. Description of the Related Art Conventionally, when a game ball passes through a start winning area provided on a game board, the left, middle, and right symbol rows displayed on a symbol display are started to change, and a predetermined time has elapsed. Later, those changes are stopped in the order of the left symbol row, the right symbol row, the middle symbol row, and if the combination of the symbols is a predetermined combination of big hit symbols, based on that,
Pachinko machines that generate a jackpot game state that is advantageous to a player are widely used. In this type of pachinko machine, the reach game state is set before the combination of the symbols in each symbol row becomes the combination of the big hit symbols. In the reach game state, the combination of the symbols in both the left and right symbol rows excluding the middle symbol row constitutes a part of the combination of the big hit symbols. And
When the symbols in the middle symbol row stopped after the lapse of the predetermined time are the same as the symbols in the reach game state, the combination of the big hit symbols is established.

[0003]

However, in the above-mentioned conventional pachinko machine, the types and arrangement of a plurality of symbols constituting each symbol row are determined in advance for each symbol row. Therefore, after the left symbol row stops, the right symbol row and the middle symbol row, which are always the same combination of symbol groups, continue to fluctuate, and after the right symbol row stops, the middle symbol row continues to fluctuate. It was scarce. For this reason, after stopping the change of the left symbol row, the player expects to be in the reach game state while watching the right symbol row that continues to fluctuate, or looks at the middle symbol row that continues to fluctuate after entering the reach game state. Although the player expects the occurrence of the jackpot game state, the expectation for the occurrence is always the same. In this respect, the conventional pachinko machine has room for improvement.

The present invention has been made in view of the above-mentioned circumstances, and has a variety of expectations for the occurrence of a special game state such as a jackpot game state, thereby providing a game with a sufficient entertainment interest to a player. It is an object of the present invention to provide a gaming machine which can be increased in number.

An operation gate 23 is provided at a substantially central portion of the game board 2 as a start winning area. On the game board 2, a normal symbol display device 24 is provided above the operation gate 23.
Is incorporated. The device 24 includes a symbol display 25 for displaying a plurality of types of image information. The image information includes a plurality of symbol rows, more specifically, a left symbol row 26 displayed on a left portion of a screen 46 of the symbol display 25, and a right symbol row 28 displayed on a right portion. The image information about the middle symbol row 27 displayed between the left and right symbol rows 26 and 28 is included.

Each of the left, middle, and right symbol rows 26, 27, 28
As shown in FIGS. 2 (a), 2 (b) and 2 (c), each is composed of a hit symbol group consisting of ten hit symbols 29 and a hit symbol group consisting of 10 hit symbols 30. I have. The winning symbols 29 and the off symbols 30 in the symbol rows 26 to 28 are alternately arranged. Each pattern 2
Numeral 9 is a candidate for a special symbol to be described later, and is composed of a picture of a balloon and numerals “0” to “9” attached to the surface thereof. Further, each of the departure symbols 30 is constituted by a picture of a windmill. And the symbol display 25
Shows some symbols (about three symbols) of each of the symbol columns 26, 27, and 28.

When the game ball 20 passes through the operation gate 23, the symbols in the left symbol row 26 displayed on the symbol display 25 change (fluctuate) in the order shown in FIG.
Let me do. The change of this symbol is from T1
It is stopped after a lapse of seconds. Further, when the game ball 20 passes through the operation gate 23, the symbols in the right symbol row 28 displayed on the symbol display 25 are changed in the order shown in FIG. The fluctuation of the symbol is stopped after a lapse of T2 seconds (> T1) after passing through the operation gate. Further, when the game ball 20 passes through the operation gate 23, the symbols in the middle symbol row 27 displayed on the symbol display 25 are changed in the order shown in FIG. This fluctuation of the symbol is stopped after a lapse of T3 seconds (> T2) from passing through the operation gate. Thus, three symbol rows 26 to 2
In 8, the variation is stopped in the order of the left symbol row 26, the right symbol row 28, and the middle symbol row 27.

When the fluctuation of all the symbol columns 26, 27 and 28 is stopped, the combination of the symbols displayed on the symbol display 25 is replaced with the predetermined combination of the big hit symbols (specific display result, Hereinafter, it may be simply referred to as “combination of big hit symbols”). Here, the combination of the big hit symbols is a combination when the hit symbols 29 of the respective symbol rows 26, 27, 28 are arranged in the same pattern on the hit lines L1, L2, L3, L4, L5. . As shown by ** in FIG. 3, the combination of the big hit symbols is the case where the same hit symbols 29 are arranged in the upper row of the symbol display 25 (FIG. 3 (a)) or in the middle row (FIG. 3 (b)). )), When they are arranged in the lower row (FIG. 3C), when they are arranged in the lower right (FIG.
(D)), and 5 (FIG. 3 (e))
There are types. In addition, the symbol which comprises the combination of a big hit symbol is equivalent to a special symbol.

When the combination of the big hit symbols is established,
You will be entitled to three rights. This right guarantees the arrival of the jackpot game state as a special game state that is advantageous to the player, specifically, the acquisition of more prize balls. The opening and closing cycle of the winning opening 14 is repeated 16 times (round). The special winning opening 14 is opened until one of the following two conditions (a) and (b) is satisfied first. The condition (a) is that ten gaming balls 20 are won in the special winning opening 14, and the condition (b) is that 9.5 seconds have elapsed since the opening of the special winning opening 14. Details of these will be described later.

The three types of symbol rows 26 to 2 described above are used.
In FIG. 8, the middle symbol row 27 in which the change is stopped lastly corresponds to a special game fixed symbol row for determining a jackpot gaming state advantageous to the player. The right symbol row 28, which stops changing before the middle symbol row 27, corresponds to a reach game confirmed symbol row for determining a reach game state that occurs prior to the big hit game state. In the reach game state, the middle symbol row 27
, The hit symbols 29, 29 of the left and right symbol rows 26, 28 stop at the same symbols on the hit lines L1 to L5.

As shown in FIG. 1, the game board 2 has an operation gate switch 31, a special device switch 32, a starting port switch 33, and a count switch for detecting a game situation which changes according to the operation of the player. Switches 34 are respectively mounted. The operation gate switch 31 is the game ball 2
The passage of 0 at the operation gate 23 is detected. The special device switch 32 detects the passing of the game ball 20 in the special device operation area 18, the starting port switch 33 detects the winning of the game ball 20 into the starting port 12, and the count switch 34 detects the game ball 20. The winning in the special winning opening 14 is detected.

Based on the detection results of the switches 31 to 34, the pachinko machine 1 has a control device 35 for driving and controlling the symbol display 25, the specific winning opening solenoid 17, the stopping device 19, and the special winning opening solenoid 22. Is provided. As shown in FIG. 4, the control device 35 includes a central processing unit (CPU) 36, a read-only memory (ROM) 37, a random access memory (RAM) 38, and an input port 39.
And an output port 40, which are connected to each other by a bus 41. The ROM 37 stores control programs, image information data, initial data, and the like in advance. The CPU 36 executes various arithmetic processes according to the control program and the like. The RAM 38 temporarily stores the calculation results of the CPU 36, for example, the values of a counter C, a flag F, and a random number counter, which will be described later.

The various switches 31 to 34 described above are connected to an input port 39, and both the solenoids 17 and 22, the stopping device 19 and the symbol display 25 are connected to an output port 40. The detection signals of the switches 31 to 34 are input to the input port 39. The CPU 36 drives and controls the solenoids 17 and 22, the stationary device 19 and the symbol display 25 via the output port 40 in response to the input signal.

Next, the operation and effects of the first embodiment configured as described above will be described. 5 to 7 show a main routine executed by the CPU 36, which is repeatedly executed after the power to the pachinko machine 1 is turned on. Each processing of this routine is executed based on the counter C, the flag F and the random number counter. Counter C
Is for counting the number of rights remaining at the start of the next control routine, and "2", "1",
Take the value of "0" in order. The flag F is for determining the probability mode, and is set to “0” in the low probability mode, and is switched to “1” in the high probability mode. When the flag F is set to "1", the probability of the symbol combination being a big hit on the symbol display 25 is increased by another routine (not shown) as compared with the case where the flag F is "0". It becomes easy to establish a combination of symbols. The random number counter is for determining whether or not it is time to change the symbol when the game reaches the reach game state, and takes an integer from “0” to “300”, for example.
While the pachinko machine 1 is operating, the random number counter performs an increment operation by “1” every time a predetermined time (for example, 2 ms) elapses, and returns the count value to “0” when it reaches “300”.

Incidentally, these counter C, flag F and random number counter are all initialized by an initial routine (not shown) executed when a power switch (not shown) of the pachinko machine 1 is turned on. . The initial values of the counter C and the flag F are both “0”.

Now, when the game is started by the player,
The CPU 36 determines whether or not the gaming situation satisfies the first condition in step 100 of FIG. Specifically, based on the detection signal of the operation gate switch 31,
It is determined whether or not the game ball 20 has passed the operation gate 23. If this determination condition is not satisfied, the main routine ends. If the condition is satisfied, step 10
In step 1, the value of the random number counter at that time is obtained (stored). In step 105, all the symbol rows 2
At 6 to 28, a signal for changing the symbol is output to the symbol display 25. In response to this signal, the symbol display 25 starts changing symbols in all the symbol rows 26 to 28 that have been stopped. Some of the symbols in each of the symbol columns 26 to 28 displayed on the symbol display 25 change as time passes. As a result, to the player, each of the left, middle, and right symbol rows 26 to 28 appears to be rotating.

Next, at step 110, the CPU 36 determines whether or not T1 seconds have elapsed since the start of the symbol change. If this determination condition is not satisfied, the process of step 110 is repeated.
At 15, a signal for stopping the symbol change in the left symbol row 26 is output to the symbol display 25. In response to this signal, for example, as shown in FIG. 8, a hit symbol 29 with “8” is displayed on the upper left portion of the symbol indicator 25,
A departure symbol 30 is displayed in the middle row, and a hit symbol 29 with “7” is displayed in the lower row. At this time, the symbols in the middle symbol row 27 and the right symbol row 28 keep changing.

The CPU 36 determines in step 120 in FIG. 5 whether or not T2 seconds (> T1 seconds) has elapsed since the start of the symbol change. If the determination condition is not satisfied, the process of step 120 is repeated. If the determination condition is satisfied, a signal for stopping the symbol change in the right symbol column 28 is output to the symbol display 25 in step 125.
In response to this signal, for example, as shown in FIG.
Is displayed in the middle row, and a hit symbol 30 with "7" is displayed in the lower row. The hit symbol 29 displayed in the lower row is the same as the hit symbol 29 displayed in the lower row of the left symbol row 26. At this time, the symbols in the middle symbol row 27 continue to fluctuate.

At step 130 in FIG. 5, the CPU 36 determines whether or not the combination of the symbols displayed on the symbol display 25 is the same as the combination in the reach game state, that is, the left and right symbol rows 26 and 28. It is determined whether or not the hit symbols 29, 29 are stopped at the same symbol in at least one of the five types of hit lines described above. When this determination condition is satisfied, the process proceeds to step 131, and it is determined whether the second condition is satisfied. In particular,
It is determined whether or not the random number obtained in step 101 is a predetermined symbol change random number. The symbol change random number is one or more numbers from “0” to “300”. If the determination condition of step 131 is satisfied, in step 135, of the winning symbol group in the middle symbol row 27, the winning symbol 2 before and after the same symbol as the reach game state
A signal for changing the symbols 9 and 29 to the same hit symbols 29 and 29 as the symbols is output to the symbol display 25, and step 1 is executed.
Move to 40.

For example, in FIG. 8, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are the same hit symbol 29 (the hit symbol with "7"). In step 130, it is determined that the game is in the reach game state. In the reach game state, as long as the middle symbol row 27 is stopped at the same symbol as the symbol in the reach game state, it becomes a combination of big hit symbols, so this last symbol row is the same symbol as the symbol in the reach game state. It is expected by players to stop at. Here, since the game is in the reach game state at “7” as described above, in step 135, as shown in FIG. 9, the hit symbol (““ 7 ”) before the hit symbol 29 with“ 7 ”is added. 8 ") 29 and the rear winning symbol (" 6 ") 29 are both changed to the winning symbol 29 with" 7 "(see the dashed line in FIG. 9). Therefore, when the symbol in the middle symbol row 27 changes, the hit symbol 29 with "7", which is the same symbol as in the reach game state, is displayed three times in succession.

If the determination condition of the step 130 is not satisfied (not in the reach game state), or the determination condition of the step 130 is satisfied but the determination condition of the step 131 is not satisfied (the acquired random number). Is not a symbol change random number), the CPU 36 proceeds to step 140 without performing the processing of step 135.

In step 140, the CPU 36 determines whether or not T3 seconds (> T2 seconds) has elapsed since the start of the symbol change. If the determination condition is not satisfied, the process of step 140 is repeated. If the determination condition is satisfied, a signal for stopping the symbol change in the middle symbol column 27 is output to the symbol display 25 in step 145 of FIG. . Then, the middle symbol row 27, which has fluctuated until the end, also stops its fluctuation. That is, the symbol fluctuation of all the symbol rows 26 to 28 is stopped.

In step 150, the CPU 36 determines whether or not the combination of the symbols displayed on the symbol display 25 is a big hit combination, that is, the hit symbol 29 of the left, middle and right symbol rows 26 to 28. , 29, 29 are stopped in at least one of the five types of hit lines L1 to L5 with the same symbol. If this determination condition is not satisfied, the main routine ends, and
If the condition is satisfied, the process from step 155 is executed.

In step 155, the CPU 36 determines whether or not the value of the counter C is "0". If this determination condition is satisfied (C = 0), the value of the counter C is set to “2” in step 160, and the process proceeds to step 170. On the other hand, if the determination condition of step 155 is not satisfied (C ≠ 0), it is determined that the right generated by the combination of the big hit symbols is still left for one or two times. Is subtracted by "1", and the routine goes to step 170. In step 170, the flag F is set to "1" to set the high probability mode.

Next, the CPU 36 excites the specific winning opening solenoid 17 in step 175. Then, the shutter 16 is brought into a substantially horizontal state by the solenoid 17, and the passage entrance of the specific winning opening 13 is opened. With this opening, it becomes possible to win a prize in the specific winning opening 13 of the game ball 20. At this time, the special device operation area 18 is shut off by the stopping device 19. For this reason, when the game ball 20 has won the specific winning opening 13 being opened, it cannot pass through the operation area 18, but one of the game balls 20 can be stopped before the operation area 18. . In step 185, it is determined whether or not a predetermined time (5.9 seconds) has elapsed from the start of opening of the specific winning opening 13. If this determination condition is not satisfied, step 17
Step 5 is repeated.

On the other hand, if 5.9 seconds have passed since the opening of the specific winning opening 13 and the determination condition of step 185 is satisfied, the CPU 36 deactivates the specific winning opening solenoid 17 in step 190. Then, the shutter 16 is set to a substantially vertical state by the solenoid 17, and the specific winning opening 13 is closed. And step 1
At 95, it is determined whether or not a predetermined time (for example, 2.0 seconds) has elapsed since the closing of the specific winning opening 13. If this determination condition is not satisfied, the process of step 195 is repeated. If the determination condition is satisfied, at step 200, a signal for operating the stopping device 19 is output. In response to this signal, the stopping device 19 opens the special device operating area 18. Since there is nothing to keep the game ball 20 stopped, if the game ball 20 is stopped before the special device operation area 18 before that,
The game ball 20 whose parking has been released can pass through the operation area 18.

Next, the CPU 36 proceeds to step 205 in FIG.
In, based on the detection signal of the special device switch 32, it is determined whether or not the game ball 20 has passed the special device operation area 18. If this determination condition is not satisfied, that is, the gaming machine 20 has not originally won the specific winning opening 13 or has won the special device operating area 18
The main routine is terminated if the vehicle has passed any other path. On the other hand, if the determination condition in step 205 is satisfied, the special device is operated in step 210. This operation guarantees one-time right acquisition. Then, in step 215, the flag F is switched from "1" to "0", and the probability mode is changed from the high probability mode to the low probability mode.

In step 220, the CPU 36 determines whether or not the game ball 20 has won the starting port 12 based on the detection signal of the starting port switch 33. That is, during the period in which the special device is operating, the game ball 20 is
Rotating body 15 entering the entrance of
Then, it is determined whether or not the vehicle has passed near the starting port switch 33 after being transported downward. If this determination condition is not satisfied, it is determined that the game ball 20 has not won the starting port 12 even though the special device is operating, and the process of step 220 is repeated. In contrast, step 220
Is satisfied, the large winning opening solenoid 22 is excited in step 225. Then, the left and right blades 21 and 21 are opened by the solenoid 22, the substantial opening area of the special winning opening 14 is enlarged, and the gaming ball 20 can easily win.

After opening the special winning opening 14, the CPU 36 determines in step 230 whether or not ten gaming balls 20 have won the special winning opening 14 based on the detection result of the count switch 34. If this determination condition is not satisfied, it is determined in step 235 whether or not a predetermined time (for example, 9.5 seconds) has elapsed since the opening of the special winning opening 14. If this determination condition is not satisfied, the processing of steps 230 and 235 is repeated. As a result, Grand Prize Winner 1
Unless ten gaming balls 20 win after the opening of 4, or 9.5 seconds elapse after the opening starts, the big winning port 14 is kept open.

If any one of the determination conditions in steps 230 and 235 is satisfied, the CPU 36 proceeds to step 240
, The large winning opening solenoid 22 is demagnetized. Then, the left and right blades 21 and 21 that have been opened up to that time are displayed.
Is closed, and the special winning opening 14 is returned to the normal state. Thereafter, in step 245, the winning of the game ball 20 to the starting port 12 is performed by the starting port switch 33 for 16 times.
It is determined whether it has been detected twice. If this determination condition is not satisfied, the above-described steps 220 to 245 are repeated. Therefore, once the special device is operated (rights are guaranteed), the game ball 20 is moved to the starting port 1.
Until the second prize is won 16 times, the special winning opening 14 repeats the cycle of opening and closing.

When the game ball 20 wins the starting port 12 16 times and the judgment condition of step 245 is satisfied, that is, when one right is consumed, the CPU 36 stops the operation of the special device in step 250. Let it. Thereafter, in step 255, it is determined whether or not the value of the counter C is “0”. If this determination condition is satisfied (C = 0), it is determined that all three rights have been consumed, and in step 260, the flag F is set to "0", and the main routine ends. If the determination condition in step 255 is not satisfied (C ≠ 0), it is determined that the right still remains for two or one times, and step 26
At step 5, the flag F is set to "1" and the main routine ends. Therefore, when the right remains, the next control routine is started in the high probability mode.

According to the main routine, during the period until the symbol displayed on the symbol display 25 becomes a combination of big hit symbols and the special device is activated, the flag F is set.
Is set to “1”. Further, the flag F is set to “1” in a period from the end of the first operation to the start of the second operation of the special device and in a period from the end of the second operation to the start of the third operation. During these periods, the probability of a big hit is increased. That is, when the right remains, the combination of the symbols when the symbol rows 26 to 28 stop changing is more likely to be the combination of the big hit symbols than in the normal case. In periods other than the above, the flag F is set to “0”, and the probability of the combination of the big hit symbols is reduced.

In the first embodiment, the above-mentioned operation gate switch 31, the processing of step 100 by the CPU 36 in the main routine, and the processing of step 131 similarly constitute a game situation detecting means. In the main routine, the processing of steps 100 and 105 by the CPU 36 corresponds to the display control means, the processing of steps 150 to 265 corresponds to the special game state generating means, and the processing of step 135 corresponds to the symbol changing means.

As described above, according to the first embodiment, when the symbol change in the predetermined symbol row (right symbol row 28) is stopped, the symbol change is scheduled to be stopped next in the symbol display 25. In the display position of the middle symbol row 27, a symbol row different from the normal time is variably displayed. Here, a part of the symbols in the middle symbol row 27, which continue to fluctuate after the reach game state is established, is changed to another symbol and displayed. For this reason, a player who notices a symbol change after the reach game state is established, a symbol different from the normal time is stopped in a symbol row scheduled to stop changing next, and a big hit game state may occur. Expectations can be made.

As described above, according to the first embodiment, when the game enters the reach game state with the symbol change random number acquired, a part of the symbols in the middle symbol row 27 during the symbol change is changed to another symbol. . Here, the hit symbol 2 with “6”
9 and the hit symbol 29 with “8” are both “7”
Is changed to the hit symbol 29 with. Symbol display 25
, The middle symbol row 27 different from the middle symbol row seen in the normal reach game state is variably displayed. That is, in the middle symbol row 27 in the normal reach game state,
Winning symbol 29 with "6" attached, off symbol 30, "7"
Symbols are displayed in the order of the hit symbol 29 with a symbol, the off symbol 30 and the hit symbol 29 with an "8". On the other hand, in the middle symbol column 27 after the symbol is changed,・ 、
Winning symbol 29 with "7" attached, off symbol 30, "7"
Are variably displayed in the order of the hit symbol 29 attached, the missing symbol 30, the winning symbol 29 attached with "7", the missing symbol 30, and so on. Thus, the middle symbol row 27 after the symbol change
In all the symbols, the ratio of the hit symbol 29 (the same symbol as in the reach game state) occupied by “7” is higher than in the normal case. Therefore, it is possible to make the player feel that the big hit game state may be more likely to occur than in the normal state. It is possible to increase the sense of expectation for the occurrence of the jackpot gaming state, and to sufficiently enhance the interest in the game given to the player.

In particular, since the symbol row to be changed is the middle symbol row 27 (special game confirmed symbol row), during the reach game state before the occurrence of the big hit game state, the degree of occurrence of the big hit game state is usually The player can be made aware that it may be different from the time. For this reason, the player's sense of expectation regarding the occurrence of the big hit game state can be increased at a stretch in a relatively short period from the occurrence of the reach game state to the occurrence of the big hit game state.

Also, in the middle symbol row 27, symbols different from the same symbol (the hit symbol 29 with "7") in the reach game state are to be changed. Middle pattern row 27
Out of all the symbols, the hit symbol 29 originally attached with “7” that contributes to the occurrence of the big hit game state is left as it is, and a part of the symbol that does not contribute to the occurrence of the big hit game state is the same as the reach game state. It is changed to a design. Since the hit symbol 29 originally attached with "7" is left, the number of symbols that need to be changed can be reduced. By changing the number of symbols as small as possible, the ratio of the same symbols in the middle symbol row 27 as in the reach gaming state can be made higher than in the normal reach gaming state. In other words, it is possible to efficiently increase the proportion occupied by the same symbols as in the reach game state.

Further, in the middle symbol row 27, a hit symbol group having a possibility of becoming the same symbol as the reach game state is set as a symbol change target. In addition, as described above, a symbol different from the reach game state is changed to the same symbol. With this change, the proportion of the same symbols as in the reach game state in all the symbols in the middle symbol row 27 increases. Therefore, the player's expectation regarding the occurrence of the big hit gaming state can be effectively increased. In addition, the missing pattern 30
The same symbol as the reach game state is displayed three times in a row, with the effect of impressing the player's visual sense that the proportion of the same symbol as the reach game state is higher. is there.

(Second Embodiment) Next, a second embodiment of the first to third inventions will be described with reference to FIGS. The second embodiment differs from the first embodiment in part of the contents of a main routine performed by the CPU 36 (step 135). The difference will be described below. Since the configurations of the pachinko machine 1 and the control device 35 other than the main routine are the same as those of the first embodiment, the description thereof is omitted here.

The CPU 36 executes step 1 in FIG.
If both the determination conditions 30 and 131 are satisfied, the flow shifts to step 135A. In step 135A,
A signal for changing all the off symbols 30 in the middle symbol row 27 to the same symbol as the reach game state is output to the symbol display 25. For example, as shown in FIG. 8 described above, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are all hit symbols 29 with a hit symbol 29 in a reach game state. In FIG. 11, all the off symbols 30 surrounded by the dashed line in FIG. 11 are changed to the hit symbols 29 with “7”.

After executing the processing of step 135A, C
The PU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions in steps 130 and 131 is not satisfied, step 135A
The processing after step 140 is executed without performing the processing of.

In the main routine, the CPU 36
In step 135A corresponds to symbol changing means.

Therefore, the second embodiment has the same functions and effects as those of the first embodiment, and has the following features. When the pachinko machine 1 is in the reach gaming state, the display location of the middle symbol row 27 on the symbol display 25 includes the original 10 hit symbols and the 10 off symbols changed to the same symbols as in the reach gaming state. Is displayed. Out of a total of 20 symbols, 11 symbols (10 missing symbols changed to “7” by change and one hit symbol originally assigned “7”) are the same symbols as the reach game state Become.
Of all the symbols, the ratio of the same symbol as the reach game state is 1
/ 2 or more. Therefore, the player who has noticed this change has an expectation that the possibility that the middle symbol row 27 will stop at the same symbol as the reach gaming state is higher than usual, and the big hit gaming state may be considerably likely to occur. You can make it.

(Third Embodiment) Next, a third embodiment of the first to fourth inventions will be described with reference to FIGS. The third embodiment differs from the first embodiment in part of the contents of the main routine executed by the CPU 36 (step 135), as in the second embodiment. Other parts are the same as in the first embodiment, and a description thereof will be omitted here.

The CPU 36 determines in step 13 in FIG.
If both the judgment conditions of 0 and 131 are satisfied, the flow shifts to step 135B. In step 135B, a signal for changing a symbol different from the reach game state among the hit symbols in the middle symbol row 27 to the same symbol as the reach game state is output to the symbol display 25. For example, as shown in FIG. 8 described above, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are both “7”.
In the case of the reach game state in which the hit symbol 29 is attached with the symbol 29 in FIG. 13, in addition to the hit symbol 29 originally assigned with “7”, other numbers (“0” to “6”,
All the hit symbols 29 with "8" and "9") are changed to the hit symbols 29 with "7" as shown by the dashed line.

After executing the processing of step 135B, the CPU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions of steps 130 and 131 is not satisfied, the processing of step 140 and subsequent steps is executed without performing the processing of step 135B.

In the main routine, the CPU 36
In step 135B corresponds to symbol changing means.

Therefore, the third embodiment has the same functions and effects as those of the first embodiment, and has the following features. In the reach game state, a symbol group having the same symbol as the reach game state and a hit symbol group are displayed at the display position of the middle symbol column 27 on the symbol display 25. Out of all 20 symbols, 10 symbols are the same symbols as in the reach game state. Of all the symbols, the ratio of the same symbols as in the reach game state is exactly １ ／. Therefore, by notifying the player of the change of the hit symbol 29, the possibility that the middle symbol row 27 stops at the same symbol as the reach game state is higher than usual, and the big hit game state may occur with a high probability. You can have the expectation that there will be none.

(Fourth Embodiment) Next, a fourth embodiment of the first to fourth inventions will be described with reference to FIGS. The fourth embodiment is similar to the second embodiment,
A part of the contents of the main routine by the CPU 36 (step 135) is different from the first embodiment. Other parts are the same as in the first embodiment, and a description thereof will be omitted here.

The CPU 36 determines in step 13 in FIG.
If both the determination conditions of 0 and 131 are satisfied, the flow shifts to step 135C. In step 135C, in the middle symbol row 27, a signal for changing all the hit symbols 29 and all the off symbols 30 different from the symbols in the reach game state to the same symbols as in the reach game state is sent to the symbol display 25.
Output to As a result, for example, as shown in FIG. 8 described above, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are both reach symbols 29 each having a hit symbol “7”. In the case of, in addition to the hit symbol 29 originally given with "7" in FIG. 15, all the hits with other numbers ("0" to "6", "8", "9") are added. The symbol 29 and all the symbols 30 are hit symbols 2 with “7” as shown by the dashed line.
It is changed to 9.

After executing the processing of step 135C, the CPU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions of steps 130 and 131 is not satisfied, the processing of step 140 and subsequent steps is executed without performing the processing of step 135C.

In the main routine, the CPU 36
In step 135C corresponds to symbol changing means.

Therefore, the fourth embodiment has the same functions and effects as those of the first embodiment, and has the following features. When the reach game state is entered, all the hit symbols 29 in the same symbol as in the reach game state, and all the miss symbols, are displayed on the symbol display 27 at the display position of the middle symbol row 27 in which the symbol change is to be stopped last. The symbol 30 is displayed. Of all the 20 symbols, all (20) symbols are the same symbols as in the reach game state. Of all the symbols, the proportion occupied by the same symbols as in the reach game state is exactly 100%. Therefore, the player who noticed the change in the symbol, the middle symbol row 2
7 is very likely to stop at the same symbol as the reach gaming state, and it can be expected that a jackpot gaming state may occur.

(Fifth Embodiment) Next, a fifth embodiment which embodies the sixth invention will be described with reference to FIGS. The fifth embodiment is similar to the second embodiment in that the CPU 3
6 (step 13)
5) is different from the first embodiment. Other parts are the same as in the first embodiment, and a description thereof will be omitted here.

The CPU 36 determines in step 13 in FIG.
If the determination condition of 0 is satisfied, the process proceeds to step 131A, and it is determined whether the random number obtained in step 101 is a predetermined symbol display prohibition random number. The symbol display prohibition random numbers are "0" to "3" in the same manner as the symbol change random numbers.
00 ”. Step 131
If the determination condition of A is satisfied, a signal for prohibiting the display of all the off symbols 30 in the middle symbol row 27 is output to the symbol display 25 in step 135D. As a result, for example, as shown in FIG. 8 described above, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are both reach symbols 29 each having a hit symbol “7”. In the case of, all the off symbols 30 in the middle symbol row 27 are not displayed, and the original hit symbol 29
(10 hit symbols with “0” to “9”) are displayed.

After executing the processing of step 135D, the CPU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions in steps 130 and 131 is not satisfied, the processing in step 140 and subsequent steps is executed without performing the processing in step 135D.

In the main routine, the CPU 36
In step 135D corresponds to a display prohibition unit.

Therefore, the fifth embodiment has the same functions and effects as those of the first embodiment, and has the following features. In the reach gaming state, only the original hit symbol 29 is displayed on the symbol display device 25 at the display position of the middle symbol row 27 in which the symbol change is to be stopped last. The number of displayed symbols is reduced from 20 to 10, and one of them is the same symbol as in the reach game state.
Therefore, the player who notices that the symbol 30 has disappeared due to the prohibition of the display of the symbol has a higher possibility that the middle symbol row 27 stops at the same symbol as the reach gaming state than usual, and the big hit gaming state occurs. You can have the expectation that you might.

(Sixth Embodiment) Next, a sixth embodiment which embodies the seventh invention will be described with reference to FIGS. The sixth embodiment has a CPU similar to the second embodiment.
36 (part 13)
5) is different from the first embodiment. Other parts are the same as in the first embodiment, and a description thereof will be omitted here.

The CPU 36 determines in step 13 in FIG.
If the determination condition of 0 is satisfied, the process proceeds to step 131B, and it is determined whether or not the random number acquired in step 101 is a predetermined symbol addition random number. The symbol addition random number is one or more numbers from "0" to "300" like the symbol change random number. If the determination condition of step 131B is satisfied, in step 135E, of the winning symbol group in the middle symbol row 27, the same symbol as the reach gaming state is added immediately before and immediately after the same symbol as the reach gaming state. Is output to the symbol display 25.
Here, “immediately before” refers to the space between the same symbol as the reach game state and the preceding symbol 30, and “immediately after” refers to the space between the same symbol as the reach game state and the subsequent symbol 30. . As a result, for example, as shown in FIG. 8 described above, the lower symbol in the left symbol row 26 and the lower symbol in the right symbol row 28 are both hit symbols 29 with “7”.
In the case of the reach game state, two hit symbols 29 each having "7" as shown by a dashed line before and after the hit symbol 29 originally having "7" in the middle symbol row 27. Is added and displayed.

After executing the processing of step 135E, the CPU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions in steps 130 and 131 is not satisfied, the processing in step 140 and subsequent steps is executed without performing the processing in step 135E.

In the main routine, the CPU 36
In step 135E corresponds to symbol adding means.

Therefore, the sixth embodiment has the same functions and effects as those of the first embodiment, and has the following features. In the reach gaming state, a larger number of hit symbols 29 are displayed at the display position of the middle symbol column 27 on the symbol display 25 than in the normal state. 20 displayed symbols
From 22 to 22, three of which have the same design as the reach game state. Moreover, these three symbols are displayed continuously. Therefore, the player who has noticed this symbol increase has a higher possibility that the middle symbol row 27 will stop at the same symbol as the reach gaming state than in the normal state, and a bigger hit state may occur than in the normal state. Can be embraced.

(Seventh Embodiment) Next, a seventh embodiment of the first to fourth, sixth, and seventh aspects of the present invention will be described with reference to FIGS. The seventh embodiment is different from the above-described left, middle, and right three symbol rows 26 to 28,
The point that image data and character data relating to a plurality of symbol rows are created and stored in the ROM 37, the point that a part of the main routine by the CPU 36 (step 135) is changed, The second embodiment differs from the first embodiment in that a selection switch (not shown) operated by a player to select one from is provided. These differences will be described below.

The CPU 36 determines in step 13 in FIG.
If both the judgment conditions of 0 and 131 are satisfied, the process proceeds to step 132. In step 132, the ROM 37
The image data and the character data relating to the plurality of symbol rows stored in the memory are read out, and a signal for displaying the symbol row and the character string on the symbol display 25 is output. In response to this signal, a plurality of (five in the figure) symbol rows 42 are displayed on the screen of the symbol display 25 as shown by a two-dot chain line in FIG.
a, 42b, 42c, 42d, 42e and one of them
Prompt to select one "Please select one design"
Is displayed. Symbol 42a here
Reference numerals 42e to 42e may be the symbol rows after the change described in the first to fourth embodiments, the symbol rows after the display prohibition described in the fifth embodiment, or the sixth embodiment. The symbol row after the symbol addition described in the above may be used.

Next, the CPU 36 determines in step 13 of FIG.
In 3, it is determined whether or not one of the plurality of symbol rows displayed on the symbol display 25 has been selected by the player based on the signal from the selection switch. If this determination condition is not satisfied, the process of step 133 is repeated, and if satisfied, the process proceeds to step 134, where a signal for changing the middle symbol column 27 displayed so far to the selected symbol column is output. Is output to the symbol display 25.

After executing the processing of step 134, the CPU 36 executes the processing of step 140 and thereafter. If any one of the determination conditions in steps 130 and 131 is not satisfied, step 1
The processing after step 140 is executed without performing the processing of steps 32 to 134.

In the main routine, the CPU 36
The processing in steps 131 to 133 corresponds to the game situation detecting means, and the processing in step 134 corresponds to the symbol changing means.

Accordingly, the seventh embodiment has the same functions and effects as those of the first embodiment, and has the following features. When the reach game state is reached, the symbol columns 42a to 4 to be replaced with the middle symbol columns 27 are displayed on the symbol display 25.
A plurality of 2e are displayed, and one of them is selected by the player. Therefore, also in this case, the player is expected to expect that the middle symbol row 27 that stops changing at the end is more likely to stop at the same symbol as the reach gaming state than usual, and that a big hit gaming state may occur. Can be embraced. In addition, since the selection of the symbol rows 42a to 42e is left to the player, the sense of expectation can be further increased.

(Eighth Embodiment) Next, an eighth embodiment which embodies the first and fifth to seventh inventions will be described with reference to FIG. The eighth embodiment is similar to the second embodiment,
A part of the contents of the main routine by the PU 36 is different from the first embodiment. Other parts are the same as in the first embodiment, and a description thereof will be omitted here.

When the game is started by the player, the CP
U36 determines in step 100 whether the game situation satisfies the first condition. More specifically, it is determined whether or not the game ball 20 has passed through the operation gate 23, and if this determination condition is satisfied, the count value of the random number counter at that time is obtained (stored) in step 101.
I do. In step 105, all the symbol rows 26 to 28
To start the symbol change. In step 110,
It is determined whether T1 seconds have elapsed since the start of the symbol change, and if this determination condition is satisfied, step 115 is performed.
In, the symbol change in the left symbol row 26 is stopped. Up to this point, the operation is the same as in the first embodiment.

Next, the CPU 36 executes steps 116 and 11
At 7, it is determined whether the second condition is satisfied. Specifically, in step 116, it is determined whether or not the symbol displayed after the fluctuation stop is the hit symbol 29. In step 117, the step 101
Then, it is determined whether or not the random number acquired in the step is a predetermined symbol change random number. If the determination conditions in steps 116 and 117 are both satisfied, a signal for changing the right symbol column 28 is output to the symbol display 25 in step 118. Examples of this change include the following (a) to (f). (A) As in the first embodiment, of the winning symbols 29 in the right symbol row 28, at least one immediately before and after the same symbol as the stopped symbol in the left symbol row 26 is changed to the same symbol as the stopped symbol. . (B) As in the second embodiment, at least a part of the off symbol 30
Is changed to the same symbol as the stopped symbol in the left symbol column 26.
(C) As in the third embodiment, the hit symbol 29 different from the stop symbol in the left symbol row 26 is changed to the same symbol as the stop symbol. (D) As in the fourth embodiment, all the hit symbols 29 and all the off symbols 30 different from the stop symbols in the left symbol row 26 are changed to the same symbols as the stop symbols.
(E) As in the fifth embodiment, display of all the off symbols 30 is prohibited. (F) Another symbol is added as in the sixth embodiment.

After executing the processing of step 118, the CPU 36 proceeds to step 120. Step 1
If either one of the determination conditions is not satisfied, that is, if the symbol displayed after the stoppage of the change is the off symbol 30 or the hit symbol 29 but not the symbol change random number, step 118 The process proceeds to step 120 without performing the processing of (1).

In step 120, the CPU 36 determines whether or not T2 seconds (> T1 seconds) has elapsed since the start of the symbol change, and if this determination condition is satisfied, in step 125, the right symbol row 28 Stop the symbol fluctuation in. Next, in step 140, it is determined whether or not T3 seconds (> T2 seconds) has elapsed since the start of the symbol fluctuation. Subsequent processing is the same as in the first embodiment.

Step 100 by the operation gate switch 31 and the CPU 36 in the main routine.
, The processing in step 116, and the processing in step 131 constitute a game situation detecting means. In the main routine, the processing of step 118 by the CPU 36 corresponds to symbol changing means.

Therefore, the eighth embodiment has the same functions and effects as the first embodiment, and has the following features. When the symbol change of the left symbol row 26 is stopped before the reach game state is established, the symbol change is stopped next on the symbol display unit 25 among the left symbol row 26 and the right symbol row 28 constituting the reach game state. At the display location of the right symbol row 28 to be made to be displayed, a symbol row different from the normal symbol row is variably displayed. Therefore, the player who has noticed the change in the symbol has the expectation that the symbol different from the normal time may stop, that is, the game may reach the reach game state, and eventually the jackpot game state may occur. be able to.

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

(1) The present invention can be applied to a game machine having a symbol display. As such a game machine, other than the pachinko machine 1, there are an arepachi, an arrangement ball, a throttle machine, and the like. For example, in the case of a throttle machine, the symbol display is started to fluctuate on the symbol display in response to player operations such as medal insertion and lever operation.

(2) Symbol display 25 in each embodiment
The display form of the symbol row in the above may be variously changed. For example,
Change the number of symbol rows to one, two, four or more,
Each symbol row may be arranged and displayed so as to extend in the horizontal direction.

In particular, when the symbol row is changed to one, the symbol row starts to fluctuate in the symbol row when the game ball passes through the operation gate, and the fluctuation is stopped after a predetermined time has elapsed. If the stop symbol is a preset specific symbol, a big hit gaming state advantageous to the player is generated based on the specific symbol.
In the middle of such a series of operations, when the second condition is satisfied before the occurrence of the big hit gaming state (for example, when a little time has passed from the start of the symbol change in a state where the symbol change random number is acquired), the symbol row is changed. Replace with another symbol row or change the symbol. In addition, a specific character is displayed during the symbol change, and when the symbol is displayed, the symbol column is replaced with another symbol column or the symbol is changed.
Also according to this embodiment, the player who notices the symbol change is more likely to stop the changing symbol row at a symbol different from the normal time than the normal time, and expects that a big hit gaming state may occur. I can make you feel.

(3) In the first embodiment, of the winning symbol group, only the winning symbol 29 immediately preceding the same symbol as in the reach game state may be changed, or only the winning symbol 29 immediately behind may be changed. May be changed. In this way, the same hit symbol as in the reach game state is displayed in a continually fluctuating manner twice, so that the sense of expectation for the occurrence of the big hit game state can be increased as in the first embodiment. Further, in connection with this, at least one of m (m is an integer of 2 or more) before and n (n is an integer of 2 or more) before and after the same symbol as the reach game state is displayed in the reach game state. It may be changed to the same pattern as.

(4) In the second embodiment, only a part of the off symbol 30 may be changed to the same symbol as in the reach game state. For example, similarly to the first embodiment and the above (3), at least one of the front and the back of the same symbol as the reach game state may be changed to the same symbol as the reach game state in the off symbol group.

(5) In the fourth embodiment, when the game reaches the reach game state, a part of the hit symbol 29 different from the reach game state in the middle symbol row 27 and a part of the off symbol 30 are set in the reach game. You may change to the same design as the state.

(6) In the fifth embodiment, when the game reaches the reach game state, the off symbol 30 in the middle symbol row 27
May not be displayed.

(7) In the fifth embodiment, the middle symbol row 2
Instead of 7, display of some symbols in the right symbol row 28 may be prohibited. In this way, a player who notices that some symbols are not displayed may stop a symbol different from the normal time, that is, a reach game state, and eventually a big hit game You can have the expectation that a condition may occur. In the fifth embodiment, display of some symbols in the right symbol row 28 in addition to the middle symbol row 27 may be prohibited. By doing so, the prohibition of the display of symbols in the right symbol row 28 before the formation of the reach gaming state causes the player to enter the reach gaming state, and eventually has an early expectation that a jackpot gaming state may occur. You can make it. Then, by prohibiting the symbol display in the middle symbol row 27 after the subsequent reach gaming state is established, the player's expectation of the occurrence of the big hit gaming state can be further increased.

(8) In the sixth embodiment, a hit symbol 29 added to the middle symbol row 27 when the reach game state is entered.
May be increased or decreased. The position to be added at this time may be other than the position shown in the sixth embodiment.

(9) In the sixth embodiment, the middle symbol row 2
Instead of 7, another symbol may be added to the right symbol row 28. By doing so, the player who notices that the symbols are increasing may have a symbol different from the normal one stopped, that is, the game may reach the reach game state, and eventually the jackpot game state may occur. You can have the expectation that you will not be able to. In the sixth embodiment, another symbol may be added to both the middle symbol row 27 and the right symbol row 28. In this way, the symbol is increased in the right symbol row 28 before the reach game state is established, so that the player enters the reach game state and eventually has an expectation that the big hit game state may occur from an early stage. be able to. And the middle symbol row 27 after the succeeding reach game state is established
, The player's expectation of the occurrence of the big hit gaming state can be further increased.

(10) In the seventh embodiment, any one of a plurality of symbol rows displayed on the symbol display 25 is displayed.
One of them may be configured to be automatically selected by the control device 35.

(11) In the first to fourth and eighth embodiments, another requirement may be added as the second condition. For example, in the eighth embodiment, "the stop symbol in the left symbol column 26 is a hit symbol with a specific number" may be an additional requirement.

(12) In the first to sixth and eighth embodiments, the symbols in the middle symbol row 27 are changed.
Although the addition and the deletion (prohibition of display) are performed, the same symbol row (corresponding to 42a to 42e) as that of the seventh embodiment is created in advance, and the middle symbol row 27 is replaced with the created symbol row. You may do so.

(13) The fifth embodiment and the sixth embodiment may be combined. That is, when the pachinko machine 1 is in the reach game state, the display of at least a part of the off symbol 30 in the middle symbol row 27 may be prohibited, and the symbol 29 may be added to the middle symbol row 27. With reference to FIG. 19 described above, for example, an off symbol 30 immediately before an added symbol on the front side (a hit symbol with “7”) is added.
And the off symbol 30 immediately after the symbol on the rear side are not displayed.

(14) In each of the embodiments described above, the pachinko machine of the type in which the right is generated three times in the third type of gaming machine has been described, but the present invention can be applied to other types of pachinko machines. For example, once in the third kind,
It can also be embodied in a type that generates two or more times, or a first and second type of pachinko machine. In addition, the hit symbol is constituted by two types of symbols, a first symbol and a second symbol, and the present invention is also embodied in a pachinko machine of a type in which a big hit game state is generated only when a big hit is combined with the first symbol. it can. In this case, for example, when the left symbol row 28 stops at the first symbol, the frequency of displaying the first symbol in the right symbol row 28 is increased, or the first symbol in the middle symbol row is displayed during the reach game state. It is conceivable to increase the display frequency of the symbols.

(15) In the first to seventh embodiments,
The same symbol as the reach game state in the middle symbol row 27 ("7")
The same symbols as in the reach game state in the right symbol row 28 in the eighth embodiment in the hit symbol 29) in the eighth embodiment may be subject to symbol change as in the other symbols. For example, these symbols are changed to symbols different from the reach gaming state, and the ratio of the same symbol as the reach gaming state in the symbol row is made lower than usual. Then, it is possible to make the player feel that the big hit gaming state may be less likely to occur than usual. Even in this case, it is possible to make the sense of expectation for the occurrence of the big hit gaming state rich and varied, and to enhance the interest in the game given to the player.

(16) In the first to seventh embodiments,
The arrangement order may be changed without changing the type of the symbols constituting the middle symbol row 27. Similarly, in the eighth embodiment, only the arrangement order may be changed without changing the types of the symbols constituting the right symbol row 28.

(17) The content of the special game state may be changed to a content different from the big hit game state described in each of the above embodiments. That is, in each embodiment, p (= 10)
The large winning opening 14 is opened until the number of the gaming balls 20 is won, and the state is changed to the starting opening 12 by the gaming balls 20 being q (= 16) times.
Is continued until a prize is won, but here, the values of p and q appropriately changed are also included in the special game state.

(18) In the present invention, each of the symbol rows 26 to 28
In addition to the pachinko machines of the type in which the symbol change is automatically stopped after a predetermined time has elapsed from the start of the symbol change in the above, there is a button for the change stop, and the symbol change is stopped according to the button operation by the player It can also be embodied in pachinko machines of the type.

(19) In the reach game state, in addition to the state described in each of the above embodiments, one of a plurality of symbol rows
A state in which the combinations of the symbols in the other symbol rows other than one constitute a part of the combination of the big hit symbols, and the state in which the symbols in all the symbol rows are continuously changing. For example, in each of the above-described embodiments, a combination of symbols when the hit symbols with the number “7” are arranged on the hit line is defined as a combination of big hit symbols. Then, in this state, the so-called full-rotation reach, in which the symbols of the left and right symbol rows 26 and 28 fluctuate in a state of being aligned on the hit line,
It is included in the reach game state here.

(20) Each of the first to seventh embodiments,
It may be combined with the eighth embodiment. Specifically, if the stop symbol in the left symbol row 26 is a hit symbol in a state where the first symbol change random number is acquired, the symbol in the right symbol row 28 is changed. Thereafter, the symbol change in the right symbol row 28 is stopped, and if the stopped symbol is the same as the stopped symbol in the left symbol row 26, that is, if the game is in the reach game state, the second symbol change random number is obtained. If so, the symbol of the middle symbol row 27 that has changed to the end is changed. By doing so, the symbol change in the right pattern row 28 before the reach game state is established,
The player can be given an early expectation that the player will be in the reach game state and eventually a jackpot game state may occur. Further, the subsequent symbol change in the middle symbol row 27 after the reach gaming state is established can further enhance the player's expectation of the occurrence of the big hit gaming state.

(21) In the right symbol column 28, one of “change of symbol”, “prohibition of symbol display” and “addition of symbol” is performed, and in the middle symbol column 27, “change of symbol” and “display of symbol” are performed. Of the “prohibition” and “addition of symbols”, processes different from those for the right symbol row 28 may be performed. As this combination,
(A) “Change of symbol” in the right symbol column 28 and the middle symbol column 27
(B) "Change symbol" in right symbol column 28 and "Add symbol" in middle symbol column 27, (c)
“Digital display prohibition” in the right symbol column 28 and “change of symbol” in the middle symbol column 27, (d) “Symbol display prohibition” in the right symbol column 28 and “design of the symbol” in the middle symbol column 27 (E) "Add symbol" in the right symbol column 28 and "Change symbol" in the middle symbol column 27, and (f) "Add symbol" in the right symbol column 28 and the middle symbol column 27. "Display prohibition of symbols".

(22) One of the right symbol row 28 and the middle symbol row 27 may change the symbol row, and the other may change the symbol row.

(23) The present invention can also be applied to a gaming machine of a type in which the symbol rows stop in a different order from the above embodiments.

[0119]

As described above, in the first aspect, if the game situation satisfies the second condition before the occurrence of the special game state, a symbol row having a symbol different from the normal time is displayed on the symbol display in a fluctuating manner. Is done. Further, in the sixth invention, a symbol row composed of less symbols than the normal time is variably displayed, and in the seventh invention, a symbol row composed of more symbols than the normal time is variably displayed. Therefore, if the symbol row in which the ratio of the special symbol occupies higher than the normal time is displayed on the symbol display due to these changes, the special game state may be more likely to occur to the player than the normal time. Can be felt. Conversely, if the symbol row in which the ratio of special symbols occupies lower than normal is displayed on the symbol display, the special gaming state may be less likely to occur to the player than normal. It is possible to make them feel. Thus, the first,
According to any of the sixth and seventh inventions, it is possible to make the sense of expectation for the occurrence of the special game state rich and varied, and to sufficiently enhance the interest in the game given to the player.

In particular, in the second invention in which the symbol row to be changed is the special game confirmed symbol row, before the special game state occurs, the degree of occurrence of the special game state may be different from the normal state. It is possible to make the player aware that there is nothing. For this reason, in addition to the effect of the first aspect, it is possible to increase a player's expectation regarding the occurrence of the special game state at a stretch in a relatively short period until the occurrence of the special game state.

Further, in the fifth invention in which the symbol row to be changed is the reach game confirmed symbol row, before the occurrence of the reach game state prior to the special game state, the degree of occurrence of the special game state is normal. It may be possible for the player to notice that it may be different. For this reason, in addition to the effect of the first invention, it is possible to increase the player's expectation regarding the occurrence of the special game state early, that is, to increase the expectation that the player will enter the reach game state and eventually the special game state may occur. It becomes possible to embrace from the time.

According to the third aspect of the present invention, a symbol different from the special symbol in the special game confirmed symbol column is to be changed. Among all the symbols in the special game confirmed symbol row, the symbols that contribute to the occurrence of the special game state are left as they are, and the symbols that do not contribute to the occurrence of the special game state are changed to the special symbols. For this reason, in addition to the effect of the second invention, the number of symbols that need to be changed is reduced because the former symbol is left. By changing the number of symbols as small as possible, the ratio of special symbols in the special game confirmed symbol row can be made higher than usual. That is, it is possible to efficiently increase the ratio of the special symbols.

According to the fourth aspect of the present invention, in the special game confirmed symbol sequence, the hit symbol group having a possibility of becoming a special symbol is subjected to the symbol change. Moreover, among the winning symbol groups,
A different symbol from the special symbol is changed to the special symbol. With this change, the ratio of special symbols in the special game confirmed symbol row increases. For this reason, in addition to the effect of the third invention,
It is possible to effectively increase the player's expectation regarding the occurrence of the special game state.
