Abstract

PROBLEM TO BE SOLVED: To prevent high possibility of getting into a special game state even in a game aiming at a special game state such as a probability fluctuated big hit by a player. SOLUTION: In this game machine, special game state determining random numbers are extracted as obtained random number values at such timing that bit hit determining random values coincide with big hit determining values such as 7, 373. In each vertical line corresponding to each round (each loop) of change of bit hit determining random number values, values corresponding to probability fluctuated big hits and values corresponding to probability non- fluctuated big hits are mixed in converted values. That is, ○ and × are mixed. In the first loop, the converted values are 3, 2 normally, and when a converting table is referred to, both probability fluctuated big hits and probability non- fluctuated big hits may be generated. This means that constant generation of probability fluctuated big hits or constant generation of probability non- fluctuated big hits will not occur in the case where big hits are generated in the first loop at normal time.

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 game machine or a coin game machine, and more particularly to a game machine including a variable display device whose display state can be changed, wherein a display result on the variable display device is predetermined. The present invention relates to a gaming machine in which a predetermined game value can be given when the display mode is changed to the display mode.

[0002]

2. Description of the Related Art As a gaming machine, a variable display device having a variable display portion whose display state can be changed is provided, and when a display result of the variable display portion becomes a predetermined specific display mode, the player is provided with a variable display device. Some are configured to shift to an advantageous jackpot game state. The variable display device includes a plurality of variable display units, and is generally configured to display the display results of the plurality of variable display units at different times.
On the variable display section, for example, a plurality of identification information such as symbols are variably displayed. Usually, that the display result of the variable display unit is a combination of predetermined specific display modes,
It is called "big hit."

[0003] When a big hit occurs, for example, a big winning opening is opened a predetermined number of times, and the state shifts to a big hit game state in which a hit ball is easy to win. Then, in each open period, when a predetermined number (for example, 10) of winning prizes is won, the winning prize opening is closed. The number of opening of the special winning opening is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and if the opening time elapses even if the number of winnings does not reach a predetermined number, the winning opening is closed. Further, if a predetermined condition (for example, winning in a V zone provided in the special winning opening) is not satisfied at the time when the special winning opening is closed, the big hit game is performed even if the predetermined number of times is not reached. The state ends.

[0004] In addition, among the combinations of the display modes of "outside" other than the combination of "big hit", at the stage where a part of the display results of the plurality of variable display portions has not been derived and displayed yet, the display results are already displayed. The state in which the display mode of the variable display unit that is derived and displayed satisfies the display condition that is a combination of the specific display modes is referred to as “reach”. A player plays a game while enjoying how to generate a big hit.

When a predetermined condition is satisfied, the gaming machine is set in a special gaming state, which is a state advantageous to a player who increases the probability of generating a big hit or shortens the time required for changing symbols on the variable display section. There is something to migrate. Less than,
A state in which the probability of generating a big hit is improved is referred to as a probability change (probable change) state. A state in which the fluctuation time of the symbol is shortened is referred to as a time reduction (time saving) state. In a gaming machine having a function of shifting to a special game state such as certainty change or time saving, a player plays a game while enjoying how to generate a condition for shifting to a special game state.

[0006] Whether or not to generate a big hit is usually determined based on the count value of a counter whose value changes within a predetermined range (hereinafter, referred to as a big hit determining random number). For example, at the timing of determining whether or not to make a big hit, the random number for big hit determination at that time is compared with a big hit determination value, that is, a lottery is performed, and when both match, a big hit is generated. It is determined. In a gaming machine having a special game state, if it is determined that a special game state (for example, probable change) big hit is to be generated, it is determined whether or not to enter a special game state (for example, probable change). After all, so that the special game state occurs randomly,
Whether or not to shift to the special game state is determined based on a count value of a counter that changes in a predetermined range (hereinafter, referred to as a special game state determination random number).

Although the predetermined range in which the random number for determining a jackpot is different from the predetermined range in which the random number for determining a special game state is different, the count-up timings of those counters are often the same. For example, the value is incremented by one at the same predetermined time, and returned to 0 when the value exceeds each predetermined range.

[0008]

Then, a certain relationship may occur between the value of the random number for determining a jackpot and the value of the random number for determining a special game state. For example, the big hit determination random number takes a value in the range of 0 to 630, and the special game state determination random number takes a value in the range of 0 to 11. Further, it is assumed that when the big hit symbol determining random number value is an odd number, it is determined to enter a probable change, and when it is an even number, it is determined not to enter a probable change.

In this case, as shown in FIG. 23, while the value of the big hit determination random number makes one round (0 to 630), the special game state determination timing is determined at the timing when the big hit determination random number matches the big hit determination value. The value of the random number always becomes a value corresponding to the probability variation or a value corresponding to the non-probability variation. Note that FIG.
In the example shown in, the “counter value” described on the left side indicates the value of the big hit symbol determining random number. The “decision symbol” indicates a probable / non-probable change in accordance with the value of the special game state determination random number, a Δ mark indicates a probable change hit, and a X mark indicates a non-probable change hit.

At the time of probability change, the jackpot determination value is a prime number of 7, 29, 127, 233, 311, 373 and 43.
3,557,607,619, and 7,373 which is a prime number at the time of non-probability change (normal time). In addition, the vertical column in “value of random number for special game state determination” (collection of numerical values on the right side in FIG. 23 = acquired random number value) indicates the random number value for big hit determination during one round of the random number for big hit determination. Shows the respective values of the random numbers for special game state determination at the timing when they match the jackpot determination value. For example, 373 = 12 × 31 +
1 is that the value of the special game state determination random number repeats a change in the range of 0 to 11 times 12 times (after 12 rounds) while the value of the jackpot determination random number advances from 0 to 373, and 1 Indicates that it has become

As shown in FIG. 23, for example, in the first cycle of the change of the random number for jackpot determination (the first loop = the first column among the vertical columns of the obtained random number), the random number for jackpot determination is determined. The value of the random number for determining a special game state at the timing when matches the jackpot determination value is an odd number corresponding to the probability change. That is, it is 7,1 in the non-probable state, and 7,5,7,5,11,1,1,5,7,7 in the probable state. Further, in the second loop (the second column among the vertical columns of the obtained random number values), all of the numbers become even numbers corresponding to the non-probability.
All other loops are odd or even.

[0012] Then, it becomes possible for the player to play a game to a certain extent with the aim of generating a large hit. For example, the first and third loops shown in FIG.
If the game is performed such that the lottery of the big hit is performed during that period, the possibility of the big hit is increased. Allowing such a game may result in unfair advantage for the player.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gaming machine which does not increase the possibility of entering a special game state even when a player aims to enter a special game state such as a probable big hit. And

In a passage between the passage gate 11 and the ball outlet 13, there is a gate switch 12 for detecting a hit ball that has passed through the passage gate 11. The winning ball that has entered the starting winning port 14 is guided to the back of the game board 6 and detected by the starting port switch 17. In addition, a variable winning ball device 15 that performs opening and closing operations is provided below the starting winning port 14. The variable winning ball device 15 is opened by the solenoid 16.

An opening / closing plate 20 which is opened by a solenoid 21 in a specific game state (big hit state) is provided below the variable winning ball device 15. In this embodiment, the opening and closing plate 20 serves as a means for opening and closing the special winning opening. The winning ball that enters one (V zone) of the winning balls guided from the opening / closing plate 20 to the back of the game board 6 is detected by the V count switch 22. The winning ball from the opening / closing plate 20 is detected by the count switch 23. Variable display device 8

A hit ball firing device that hits and fires a game ball is driven by a drive motor 94 controlled by a circuit on a firing control board 91. Then, the driving force of the driving motor 94 is adjusted according to the operation amount of the operation knob 5. That is, the circuit on the firing control board 91 is controlled so that the hit ball is fired at a speed corresponding to the operation amount of the operation knob 5.

FIG. 5 is a block diagram showing the circuit configuration in the display control board 80 together with the CRT 82 as an example of the variable display section 9 and the output buffer circuit 63 of the main board 31. The display control CPU 101 controls the control data RO
It operates according to the program stored in M102, and receives a display control command via the input buffer circuit 105 when a strobe signal is input from the main board 31 via the noise filter 107 and the input buffer circuit 105. As the input buffer circuit 105, for example, a 74HC244 which is a general-purpose IC can be used.

The display control CPU 101 controls display of a screen displayed on the CRT 82 in accordance with the received display control command. Specifically, a command corresponding to the display control command is given to the VDP 103. VDP103
Reads necessary data from the character ROM 86. The VDP 103 generates a CRT 8 according to the input data.
2 is generated, and the image data is stored in the VRAM 87. Then, the image data in the VRAM 87 is converted into R, G, B signals, converted into analog signals by the DA converter 104, and output to the CRT 82.

FIG. 5 also shows a reset circuit 83 for resetting the VDP 103, an oscillation circuit 85 for supplying an operation clock to the VDP 103, and a character ROM 86 for storing frequently used image data. The frequently used image data stored in the character ROM 86 is, for example, a person, an animal, or an image composed of characters, graphics, or symbols displayed on the CRT 82.

The input buffer circuit 105 can pass a signal only in the direction from the main board 31 to the display control board 80. Therefore, there is no room for a signal to be transmitted from the display control board 80 side to the main board 31 side. Display control board 80
Even if the internal circuits are modified illegally, the signal output by the illegal modification is not transmitted to the main board 31 side. The outputs of the output ports 571 and 572 may be output to the display control board 80 as they are. However, by providing the output buffer circuit 63 capable of transmitting a signal in only one direction, the output from the main board 31 to the display control board 80 is provided. One-way signal transmission can be further ensured. Further, for example, a three-terminal capacitor or a ferrite bead is used as the noise filter 107 that cuts off a high-frequency signal. However, even if noise is present between display control commands between substrates due to the presence of the noise filter 107, the effect is eliminated. Is done.

Next, the operation of the gaming machine will be described. FIG.
5 is a flowchart showing the operation of the basic circuit 53 on the main board 31. As described above, this process is started, for example, every 2 ms by the reset pulse generated by the periodic reset circuit 66. When the basic circuit 53 is started, the basic circuit 53 first sets a clock monitor register incorporated in the CPU 56 to a clock monitor enable state in order to make the clock monitor control operable (step S1). Note that the clock monitor control is a control in which a reset is automatically generated inside the CPU 56 when a decrease or stop of an input clock signal is detected.

Next, the CPU 56 performs a stack setting process for setting the designated address of the stack pointer (step S2). In this example, 00FFH is set in the stack pointer. Then, a system check process is performed (step S3). In the system check process, the CPU 56 determines whether or not the RAM 55 contains an error.
Processing such as initializing 5 is performed.

Next, after processing for setting the command data sent to the display control board 80 to a predetermined area of the RAM 55 is performed (display control data setting processing: step S
4), a process of outputting command data as display control command data is performed (display control data output process: step S5).

Next, processing for outputting the contents of the storage area for various output data to each output port is performed (data output processing: step S6). Further, the lamp timer is decremented by one, and when the lamp timer times out (when it becomes 0), the lamp data pointer is updated and a new value is set in the lamp timer (lamp timer processing: step S7).

Further, output data setting processing for setting output data such as data of the address indicated by the lamp data pointer, jackpot information, start information, and probability fluctuation information output to the hall management computer in the storage area is performed (step S8). ). Further, various abnormality diagnosis processes are performed by a self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S9).

Next, a process of updating each counter indicating a random number for determination, such as a random number for determining a jackpot, used for game control is performed (step S10). FIG. 7 is an explanatory diagram showing each random number. Each random number is used as follows. (1) Random 1: Determine whether or not to generate a big hit (for big hit determination) (2) Random 2-1 to 2-3: For left and right middle stop symbol determination (3) Random 3: Special game state (this In the embodiment, it is determined whether or not the high probability state = probable change state (for special game state determination). (4) Random 4: Determine reach type (for reach type determination) (5) Random 5: Big hit Determine the left and right middle stop symbols (for big hit symbol determination)

Incidentally, random numbers other than the above-mentioned random numbers (1) to (5) are used to enhance the game effect. In step S10, the CPU 56 determines (1) the random number for determining a jackpot, (3) the random number for determining a special game state, and (5)
Of the counter for generating the jackpot symbol determination random number is incremented (addition of 1). That is, it is the judgment random number.

Next, the CPU 56 performs a special symbol process (step S11). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S12). In normal symbol processing, 7 segments L
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display 10 by the ED in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state.

The CPU 56 further includes a switch circuit 58
, And performs necessary processing according to the switch state (switch processing: step S1).
3). In addition, a process of transmitting audio data in the process data described later to the audio control board 70 is performed (audio processing: step S14).

The basic circuit 53 further performs a process of updating the display random number (step S15). In this embodiment, the display random numbers are random 2 and 4.

The basic circuit 53 includes a prize ball control board 37.
Is performed (step S16). That is, when a predetermined condition is satisfied, a winning ball control command indicating the number of winning balls is output to the winning ball control board 37. Award ball control board 3
The CPU for controlling a prize ball mounted on 7 drives the ball payout device 97 according to the received number of prize balls. After that, the basic circuit 53 repeats the display random number updating process in step S17 until the next reset pulse is given from the periodic reset circuit 66.

FIG. 8 is an explanatory diagram showing an example of the middle left and right symbols used in this embodiment. As shown in FIG. 8, in this embodiment, the respective symbols displayed as left and right middle symbols are the same 13 symbols in the left and right. The left and right middle symbols are variably displayed in the order of the symbol numbers. When the symbol of symbol number 12 is displayed, the symbol of symbol number 0 is displayed next.

FIG. 9 is an explanatory diagram showing an example of a judgment symbol used to notify whether or not a big hit is used in this embodiment. When a probable change notification effect is performed, 2
The two determination symbols are displayed on the variable display section 9 alternately. Therefore, the player can visually recognize the symbols shown in FIG. 9 alternately. In the case of the probability change big hit, at the end of the probability change notification effect, the display control CPU 101 stops the display with the symbol indicating the probability change hit (the symbol shown on the left side of FIG. 9).

Next, a method of determining a symbol variably displayed on the variable display section 9 based on a winning in the starting winning opening 14 will be described with reference to flowcharts of FIGS. FIG. 10 shows a process for determining that the hit ball has won the start winning opening 14, and FIG. 11 shows a process for determining the stop symbol of the variable display of the variable display unit 9. FIG. 12 is a flowchart showing a process for determining whether or not to make a big hit.

When the hit ball wins the starting winning port 14 provided in the game board 6, the starting port sensor 17 is turned on. For example, in the switch processing of step S13 of the main processing, as shown in FIG. 10, when the CPU 56 determines that the starting port sensor 17 has been turned on via the switch circuit 58 (step S41), the starting winning storage number is set to the maximum value. (Step S4).
2). If the number of stored start winnings has not reached 4, the number of stored start winnings is increased by 1 (step S43), and the value of the random number for big hit determination is extracted. Then, it is stored in the random number value storage area corresponding to the value of the number of stored start winnings (step S).
44). If the number of stored start winnings has reached 4, the process of increasing the number of stored start winnings is not performed. That is, in this embodiment, the number of hit balls that have won the maximum of four starting winning openings 17 can be stored.

Further, in the special symbol process processing of step S11, the CPU 56 confirms the value of the number of start winning combinations as shown in FIG. 11 (step S50). If the start winning prize memory number is not 0, the value stored in the random number storage area corresponding to the start prize storing number = 1 is read out (step S51), the value of the starting prize storing number is reduced by 1, and The value of the random number value storage area is shifted (step S52). That is, the number of start winning prize memories = n (n =
The values stored in the random number value storage area corresponding to (2, 3, 4) are stored in the random number value storage area corresponding to the number of startup winning storage numbers = n-1.

Then, the CPU 56 determines the hit / miss as shown in FIG. 12 based on the value read in step S51, that is, the value of the extracted big hit determining random number (step S53). Here, the big hit determination random number takes a value in the range of 0 to 630. FIG.
As shown in FIG. 3, when the probability is low, for example, the value is “7”,
If it is "373", it is determined as "big hit", and if it is any other value, it is determined as "out". When the probability is high, for example, the values are “7”, “29”, “127”, “2”.
33 "," 311 "," 373 "," 433 "," 55 "
7 "," 607 ", or" 619 ", it is determined to be" big hit "; otherwise, it is determined to be" out ".

When it is decided to make a big hit,
The CPU 56 extracts the value of the random number 5, and determines the middle left and right symbols according to the extracted value as the big hit symbols (step S6).
2). In addition, a special game state determination random number (random 3) is extracted (step S63). Further, the conversion value corresponding to the extracted special game state determination random number value is determined using the random number table (step S64). Then, it is determined whether to use the probable big hit or the non-probable big hit according to the converted value, not according to the special game state determining random value (step S65). The random number table and the conversion value will be described later in detail.

If it is determined that the probability change is a big hit (step S66), the probability change flag is turned on (step S67). If it is determined to be a non-probable variable jackpot (step S66), the probable variable flag is turned off (step S68). That is, in this example, the probable change state continues until the next big hit occurs. Then, the reach type determining random number (random 5) is extracted, and the reach type is determined based on the value (step S57).

The actual transition to the probable change state is made after the special symbol is determined (stopped) and the big hit game based on it is completed.

If it is determined that there is a loss, the CPU 56
Determines the left symbol according to the value of random 2-1 (step S58). Also, the middle symbol is determined according to the value of the random 2-2 (step S59). Then, the right symbol is determined according to the value of the random 2-3 (step S6).
0). Here, when the determined left and right middle symbols match, the symbol corresponding to the value obtained by adding 1 to the value of the random number corresponding to the middle symbol is determined as the middle symbol and is not matched with the big hit symbol.

Further, the CPU 56 decides to reach when the left and right symbols match (step S61),
The reach type determining random number is extracted, and the reach type is determined based on the extracted random number (step S57).

As described above, it is determined whether the display mode of the symbol variation based on the winning start is a jackpot, a reach mode, or a loss, and the combination of the stop symbols of each special symbol is determined. . Also, it is determined whether or not to make a probable change.

In the high probability state, the probability of the next big hit increases, the time until the variable display of the variable display 10 is determined by the 7-segment LED is shortened, and the variable display of the variable display 10 is changed. The pachinko gaming machine 1 may be configured to increase the number of times and the opening time of the variable winning ball device 15 at the time of hitting based on the result, or the probability of hitting based on the variable display result of the variable display 10 is high. It may be constituted so that it may become.
Further, the present invention is also applicable to the pachinko gaming machine 1 in which only one or a plurality of these states occur.

For example, when the combination of symbols stopped on the variable display section 9 becomes a specific symbol, the probability of a big hit does not increase, but the variable winning ball device 15 at the time of hitting based on the variable display result of the variable display 10 does not increase. Even in a gaming machine in which the number of times of opening and the opening time are increased, if it is determined that the reach is to be made, it is determined whether or not the left and right stopped symbols match the display mode of the specific symbol, that is, which symbol is used to generate the reach state The present invention is also applicable to gaming machines determined by means such as a predetermined random number.

The random number and the range of the random number value used in this embodiment are merely examples, and any random number may be used and the range may be set arbitrarily. However, a characteristic of this embodiment is that a plurality of jackpot determination values are determined even during normal times, as shown in FIG. If there are a plurality of jackpot determination values, it is easy to set the probability of a jackpot to a desired value.

When a plurality of jackpot determination values are set at a normal time, it is desirable that the denominator in calculating the jackpot probability is a prime number. However, for example, the normal jackpot probability is 1 /
For example, when it is desired to set it to 320, the denominator cannot be a prime number. Therefore, as in this embodiment (the range of the random number for determining a big hit is 0 to 630), it is preferable to set the big hit probability to 2/631 (= 1 / 315.5) close thereto.

FIG. 14 is a flowchart showing an example of a special symbol process processing program executed by the CPU 56. The special symbol process process shown in FIG. 14 is a specific process of step S11 in the flowchart of FIG. When performing the special symbol process processing, the CPU 56 determines in step S3 shown in FIG.
One of the processes from 00 to S309 is performed. In each process, the following processes are performed.

The special symbol change waiting process (step S30)
0): When variable display of special symbols can be started,
Check the number of memorized start winnings. If the number of start winning prizes is not 0, the value of the special symbol process flag is changed so that the process of step S301 is executed.

Special symbol determination processing (step S301):
It is determined whether to make a jackpot or not depending on the value of the extracted random number for jackpot determination. That is, the first half of the processing shown in FIG. 11 is executed.

Stop symbol setting processing (step S302):
The stop symbol of the left and right middle symbols is determined. That is, the middle half of the processing shown in FIG. 11 is executed.

Reach operation setting processing (step S30)
3): Whether or not to perform the reach operation is determined according to the value of the reach determination random number, and the reach type is determined according to the value of the reach type determination random number. That is, the latter half of the process shown in FIG. 11 is executed.

All symbols change start processing (step S30)
4): In the variable display section 9, control is performed so that all symbols start to change. At this time, with respect to the display control board 80,
For example, a left and right middle final stop symbol and information instructing a variation mode are transmitted.

All symbols stop waiting process (step S30)
5): Control is performed so that all symbols displayed on the variable display section 9 are stopped after a predetermined time has elapsed. Further, a command for instructing the probability change notification is sent to the display control board 80.

Jackpot display processing (step S306):
If the stop symbol is a combination of jackpot symbols,
The internal state (process flag) is updated so as to proceed to step S307. If not, the internal state is updated to shift to step S309. The combination of the big hit symbols is a combination in which the right and left middle symbols are aligned. Also, when the left and right symbols are aligned, it reaches reach.

Opening process of opening the special winning opening (step S30)
7): Control for opening the special winning opening is started. Specifically, the counter and the flag are initialized, and the solenoid 21 is driven to open the special winning opening.

Processing during opening of the special winning opening (step S30)
8): Control for transmitting display control command data of the special winning opening round display to the display control board 80, processing for confirming establishment of the closing condition of the special winning opening, and the like are performed. When the final closing condition of the special winning opening is satisfied, the internal state is updated so as to shift to step S309.

Big hit end processing (step S309):
A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flags and the like are returned to the initial state, and the internal state is updated so as to shift to step S300.

As described above, when the ball is hit in the starting winning opening 14, the basic circuit 53 determines whether to make a big hit or a loose hit, a stop symbol and a variable in the special symbol process process of step S11 (see FIG. 6). The display period is determined, and a display control command corresponding to the determination is given to the display control CPU 101 of the display control board 80. The display control CPU 101 controls the display of the variable display unit 9 according to a display control command from the main board 31.

Hereinafter, a method of determining the probability change / non-probability change according to the value of the special game state determination random number will be described. In this embodiment, it is not determined directly whether to use the probability change big hit or the non-probability change big hit based on the value of the special game state determination random number, but it is determined using the random number table and the conversion value. This has already been described (see steps S63 to S65 in FIG. 11).

FIG. 15 shows an example of the structure of the random number table and the conversion table and each loop (one of the changes in the random number for jackpot determination).
It is explanatory drawing which shows the transition of the random value for special game state determination, and a conversion value in (around). In the process of step S64,
A conversion value is determined using the extracted value of the special game state determination random number and the random number table. The relationship between the value of the special game state determining random number and the converted value in the random number table is such that the jackpot determining random number value matches the jackpot determination value while the value of the jackpot determining random number makes one round (0 to 630). Each conversion value at the timing is set so as not to be biased to a value corresponding to the probability change big hit or a value corresponding to the non-probability change big hit.

The random number table shown in FIG. 15 corresponds to the judgment value conversion table described in the claims, and the conversion table shown in FIG. 15 corresponds to the special game state described in the claims. Corresponds to the decision table.

Then, in step S65, using the conversion table, it is determined according to the converted value whether to use the probable big hit or the non-probable big hit. In FIG. 15, it is determined whether to use the probability variable jackpot or the non-deterministic variable jackpot.
This is indicated by a mark “〇” or a mark “X” in the “decision design” column.

Further, in this embodiment, when it is determined that a big hit is to be made, a certain-variable-information informing effect for variably displaying the judgment symbol shown in FIG. 9 is performed. At the end of the probable change notification effect, the probable design or the non-probable design of the judgment design is stopped and displayed, but the stop design corresponds to the symbol “，” and “×” in FIG.

In FIG. 15, the vertical column in the right numerical column is the special game state determining random number at the timing when the big hit determining random value matches the big hit determination value, as in the conventional example shown in FIG. Are shown below. However, in FIG. 15, the first row shows the special game state determination random value, and the second row shows the converted value. The third row indicates whether to make a probable change (〇) or a non-probable change (x). Therefore, each value in the first stage is the same value as each value shown in FIG.

In each column corresponding to each cycle (each loop) of the change of the random number for jackpot determination, looking at the values shown in the second row, the values corresponding to the probability change jackpot and the non- The value corresponding to the big hit is mixed. That is, in the third row, the symbol “〇” and the symbol “X” are mixed. For example, in the first loop, the conversion value is normally 3 or 2 at normal times, and a probability change big hit and a non-probability change big hit may occur when the conversion table is referred to. That is, when a big hit occurs in the first loop in the normal state, there is no possibility that the big hit always occurs or the big hit does not always occur.

At the time of the probability change of the first loop, the converted values are “3”, “10”, “3”, “10”,
"11", "2", "2", "10", "3", "3"
As a result, the values corresponding to the probable jackpot and the non-probable jackpot are mixed. Therefore, if a big hit occurs in the first loop even at the time of a probability change, there is no possibility that a big hit or a non-variable big hit always occurs.

The above is not limited to the first loop.
This is true for all loops. That is, in this embodiment, it is determined whether to use the probability variable jackpot or the non-deterministic variable jackpot based on the conversion value.
During the game, even in each round of the change of the random number value for determining the big hit, the case of the big hit with the probable change symbol does not concentrate.
Therefore, it is difficult for the player to play a game with the aim of making a big hit.

As is clear from the example shown in FIG.
In this embodiment, the normal jackpot determination value of 7,
As a big hit by each of 373, a case of a probability variable big hit occurs, and a non-variable big hit also occurs. For example, in the case of the big hit determination value “7”, the converted value is “3” in the first loop, and the converted value is “4” in the second loop.
Becomes a non-probable jackpot. This means that, for example, even if the timing at which the big hit determination value “7” occurs is detected, it is difficult to play a game aiming only at the certainty big hit.

Also, in this embodiment, when there is a probability change,
The jackpot determination value is from 7,373 to 7,29,127,
233,311,373,433,557,607,6
The number of hits increases to 19, but as a big hit by each of these values, a case of a probability variable big hit also occurs, and a non-variable big hit also occurs. Therefore, even at the time of the probability change, it is difficult to play a game aiming only at the probability change big hit. In this embodiment, there are a plurality of jackpot determination values at the time of normal operation. If the random number table and the symbol conversion table are configured so as to generate a non-probable jackpot and a non-probable jackpot, it becomes difficult to play a game aiming only at the probable jackpot.

In this embodiment, the range of the jackpot determining random number is from 0 to 630, and the range of the jackpot symbol determining random value is from 0 to 11. Is described, but even if their numerical ranges are different from the above-described values, by appropriately selecting the relationship between the jackpot determination random number value and the conversion value in the random number table, the jackpot determination is performed. Even in each lap of the change of the random number for use, it is possible to avoid the case where the big hits are made with the probable variable design.

The random number table and the symbol conversion table are set in the ROM 54. As shown in FIG. 15, in the conversion table, the conversion values are described in ascending numerical order. That is, they are set in numerical order. Therefore, the content of the symbol conversion table at the time of design, etc., and the selection rate (appearance rate) of the judgment symbol when a big hit occurs
Confirmation is easy.

In the above embodiment, the conversion value is determined by referring to the random number table based on the extracted special game state determination random numbers, and the probability of change is determined by referring to the conversion table based on the conversion value. Although it is determined whether to perform a non-probable variable hit or a non-probable variable big hit, it is also possible to determine whether to use a probable large hit or a non-probable variable big hit only by a random number table.

In this case, as shown on the left side of FIG. 16, in the random number table, the random numbers (counter values) for determining a special game state are arranged in ascending order. The determination results (“Δ” and “X” in the column of “determination symbol”) are arranged unevenly, that is, randomly.

FIG. 17 is a flowchart showing a process for determining a symbol for stopping variable display of the variable display section 9 when a table as shown in FIG. 16 is used. In this case, when it is determined that a big hit is to be made, the CPU 5
6 determines the big hit symbol (step S6
2) Extract a special game state determination random number (random 3) (step S63), and further, using a random number table,
It is determined whether to be a probable big hit or a non-probable big hit according to the special game state determination random value (step S64).
A).

Then, when it is determined to be the probability change big hit (step S66), the probability change flag is turned on (step S67). If it is determined to be a non-probable variable jackpot (step S66), the probable variable flag is turned off (step S68).

In FIG. 16, the vertical column in the numerical value column on the right side shows the special game state determining random number at the timing when the big hit determining random value matches the big hit determining value, as in the example shown in FIG. Each value is shown. However, the first row indicates a random value for determining a special game state, and the second row indicates whether to make a probability change (〇) or a non-probability change (×).

In each column corresponding to each cycle (each loop) of the change of the random number value for determining the big hit, the symbols Δ and X are mixed in the second row. That is, in each loop, the symbol Δ and the symbol X are mixed, and a large-variable big hit and a non-large-variable big hit may occur. In other words, when a big hit occurs at each loop in the normal state, there is no possibility that the big hit always occurs or the big hit does not always occur.

In addition, even in the case of a certainty change, the symbol “〇” and “×”
And are mixed. That is, in each loop, the symbol Δ and the symbol X are mixed, and a large-variable big hit and a non-large-variable big hit may occur. Therefore, there is no possibility that the jackpot will always be a probability variable jackpot or a non-probable variable jackpot. Therefore, even during each round of the change of the random number value for determining a jackpot during a game, the case of a jackpot with a probable variable pattern does not concentrate, so that the player also plays the game for the probable jackpot. Becomes difficult.

In the above-described embodiment, as shown on the left side of FIG. 16, the probability of the display of the judgment symbol (the ratio of the probability variation symbol) and the probability of the variable internal rush (the actual probability of occurrence of the probability variation) are the same. there were. That is, the internal rush rate was ２, and the probable change symbol was の of all judgment symbols. However, the present invention can also be applied when the display probability and the internal rush rate are different.

For example, as shown on the left side of FIG. 18, the results of the determination as to whether the hit is a probable variable hit or a non-probable variable hit (〇 and X in the column of “decision symbols”) are unequally arranged. At the same time, the number of special game state random number values to be the probability change jackpot is set to 1/3 of the whole. Therefore, the internal rush rate for the probable change state is １ ／, and the internal rush rate for the non-probable change state is ／. The probability of the display of the judgment symbol is 1/2.

In FIG. 18, in each column corresponding to each cycle (each loop) of the change of the random number value for determining a jackpot, the symbol “〇” and the symbol “X” are mixed in the second row. That is, in each loop, the symbol Δ and the symbol X are mixed, and a large-variable big hit and a non-large-variable big hit may occur. In other words, when a big hit occurs at each loop in the normal state, there is no possibility that the big hit always occurs or the big hit does not always occur.

In addition, even in the case of the probability change, the symbol “〇” and “×”
And are mixed. That is, in each loop, the symbol Δ and the symbol X are mixed, and a large-variable big hit and a non-large-variable big hit may occur. Therefore, there is no possibility that the jackpot will always be a probability variable jackpot or a non-probable variable jackpot. Therefore, even during each round of the change of the random number value for determining a jackpot during a game, the case of a jackpot with a probable variable pattern does not concentrate, so that the player also plays the game for the probable jackpot. Becomes difficult.

In this embodiment, the special game state random number value (counter value) can take a range (12 of 0 to 11).
Type) is a common multiple of the denominator (3 in this example) of the entry rate to each game state (in this example, probable change and non-probable change) and the number of game states (2 in this example). As described above, if the range in which the special game state random number value can be taken is a common multiple of the denominator of the entry rate of each game state and the number of game states, any entry rate can be easily set for any number of game states. can do.

In each of the above embodiments, there is one kind of special game state and two kinds of game states in total. However, the present invention can be applied even if the number of special game states is another kind.
For example, as shown on the left side of FIG. 19, the game state determined according to the special game state random number value (counter value) is represented by 〇,
It is assumed that there are three types, Δ and ×. For example, the symbol “〇” indicates a probable change state until the next symbol change is completed, the symbol “△” indicates a probable change state until the symbol change of 100 times is completed, and the mark “X” indicates a pattern changed for 20 times thereafter. Until the end of the fluctuation, the state is determined to be a positive change state. That is, each game state has a different degree of advantage for the player. The range in which the special game state random number value can be taken is a range of the number of game states (3 in this example) or more.

As shown on the right side of FIG. 19, even when there are a plurality of special game states having different degrees of advantage, all of the plurality of big hit determination values are used during the special game state random number rounds. Even if it is determined that all the special game states are generated as the corresponding game states.

FIG. 20 is a flowchart showing a process for determining a symbol for stopping variable display of the variable display section 9 when a table as shown in FIG. 19 is used. In this case, when it is determined that a big hit is to be made, the CPU 5
6 determines the big hit symbol (step S6
2) Extract a special game state determination random number (random 3) (step S63), and further, using a random number table,
Determine the gaming state. Then, a value corresponding to the gaming state is set in the variation counter (step S70).

Then, the probable change flag is turned on (step S67). The value of the variation counter is decremented by one when one variation is completed in the special symbol process. Further, the probability change flag is turned off when the value of the change frequency counter becomes zero.

In FIG. 19, in each column corresponding to each cycle (each loop) of the change of the random number for jackpot determination, marks corresponding to a plurality of game states are mixed in the second row. That is, in each loop, different entry conditions for the game state may be satisfied. In other words, in each loop in the normal state, the establishment of the particularly advantageous game condition occurrence conditions does not concentrate.

Therefore, even during each round of the change of the random number for jackpot determination during the game, it is difficult for the player to play the game in order to generate a particularly advantageous game state.

FIG. 21 is a timing chart showing the relationship between the change of the special symbol, the open / close state of the special winning opening, and the variable display state of the judgment symbol on the variable display section 9. In this embodiment, as shown in the timing chart of FIG. 21, the certain variation notification effect is performed from when the special symbol is determined to when the special winning opening is first opened. That is, the two types of determination symbols illustrated in FIG. 9 are displayed alternately, and after a predetermined time elapses as the probability variation notification effect time, a probability variation symbol or a non-variability variation symbol is determined. In FIG. 21, a probability change notification start command and a probability change notification end command are commands given from the main board 31 to the display control board 80.

Note that the certainty change notification effect may be performed in another period. For example, it may be performed from the first opening of the special winning opening of a predetermined number of times to the end of the last opening. Further, after the grand prize opening is finally closed, a certainty change notification effect may be performed.

FIG. 22 is an explanatory diagram showing a state of displaying a judgment symbol when there are two game states. For example, it is assumed that after a reach operation in which only the middle symbol of the special symbol fluctuates as shown in (A), a big hit is determined as shown in (B). Then, the probable change notification effect is started, and the probable change symbol (非) and the non-probability change symbol (x) of the judgment symbol are alternately displayed (see (B) and (C)). If it is determined that the symbol is to be determined, the symbol is determined with a probable variable design (see (D)).

As described above, in each of the above embodiments,
At each round of the change of the random number for big hit determination, each value of the random number for special game state determination at the timing when the random number for big hit determination matches the big hit determination value does not become a value corresponding to one game state. , A value corresponding to one of the plurality of game states. Further, as exemplified in FIG. 19, particularly at the time of the probability change, during the round of the big hit determination random value, each of the special game state determination random numbers at the timing when the big hit determination random value matches the big hit determination value. The value includes a value corresponding to all game states.

That is, the jackpot determining means updates the value at each predetermined timing (every 2 ms in this example) and sets the initial value (0 in this example) when the value exceeds the maximum value (630 in this example). When the returned jackpot determination counter is included and there are a plurality of jackpot determination values, while the value of the jackpot determination counter makes one round (0 to 6 in this example).
30), the jackpot determining means determines all of the plurality of jackpot determination values (in this example, "7", "29", "12"
7 "," 233 "," 311 "," 373 "," 43 "
3 "," 557 "," 607 ", and" 619 "), even if it is determined to be a big hit, the special game state determination means determines that all game states (for example, (Variable jackpot and non-variable jackpot). Therefore, it is difficult for the player to play a game aiming at the occurrence of a specific game state, for example, the probability of a large hit.

Further, in each of the above-described embodiments, a plurality of jackpot determination values are used in both the normal state and the probable change. If there is more than one jackpot judgment value,
If the special game state determining means is configured to generate all the special game states as the game state corresponding to each big hit determination value, the effects of the present invention can be exerted.

In each of the above embodiments, the counter for generating the special game state determination random number is 2 ms.
Although it is updated by +1 each time, it may be updated not by +1 but by discrete steps. Further, when the initial value is set by counting all the values in the predetermined range, an initial value different from the previous initial value may be set.

In each of the above-described embodiments, the probable change state is exemplified as the special game state. However, the special game state may be a time reduction state in which the symbol fluctuation time is shortened. If we replace probable changes in form with time savings,
The invention can also be applied to a game machine having a time saving function.

Further, in this embodiment, the judgment symbol is displayed on the variable display section 9, but a judgment symbol display for displaying the judgment symbol is provided separately from the variable display section for variably displaying the special symbol. You may.

[0124]

As described above, according to the present invention, the gaming machine is operated during the period in which the value of the jackpot determination counter counts once every value in a predetermined range from the initial value.
Among the plurality of count values of the special game state determination counter at a plurality of timings at which the value of the big hit determination counter matches the big hit determination value, a value for which the special game state determination means does not determine the special game state is set. Since it is configured to be included, the occurrence of the special game state can be prevented from being biased. As a result, even if the game aimed at the occurrence of the special game state is performed, the possibility of the occurrence of the special game state does not increase. This has the effect.

A special game state determining table in which information on whether or not a special game state is determined by the special game state determining means corresponding to each of the count values of the special game state determining counter is provided. When a determination value conversion table for converting the count value of the state determination counter is included, by appropriately setting the determination value conversion table, it is difficult to perform a game aimed at the occurrence of a special game state. can do. Also, by regularly arranging information in the judgment value conversion table,
It is easy to check the special game state occurrence rate when a big hit occurs.

The special game state determination means includes a special game state determination table in which information on whether or not to enter the special game state is described corresponding to each count value of the special game state determination counter. In the case where information is arranged unequally in the game state determination table, it is possible to make it difficult to perform a game aiming to generate a special game state by a simple method.

The special game state determination means includes a special game state determination table in which information on whether or not to enter the special game state is described corresponding to each count value of the special game state determination counter. The update range of the game state determination counter is 3 or more, and the type of the special game state is 3
When configured as described above, even when there are a plurality of types of special game states, it is possible to make it difficult to perform a game aiming to generate a special game state.

In the case where the update range of the special game state determination counter is configured to be a common multiple of the denominator of the entry rate into each special game state and the number of game states, if the number of game states is arbitrary, Thus, an arbitrary rush rate can be easily set.

When the special game state is the probability fluctuation state, it is possible to make it difficult for the player to play a game aiming at a certain change rush.

When the special game state is the time reduction state, it is possible to make it difficult for the player to play a game aiming for a time reduction.

When a plurality of game states have different degrees of advantage, it is difficult to perform a game aimed at the occurrence of the special game state even when the game effects in the special game state are enriched. Can be.
