Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine represented by, for example, a pachinko gaming machine, a coin gaming machine, a slot machine or the like, and more specifically, it has a variable display device whose display state can be changed, and the variable display is provided. The present invention relates to a gaming machine that can be controlled to a specific game state that is advantageous to a player when a display result of a device becomes a predetermined specific display mode.

[0002]

2. Description of the Related Art In a conventional gaming machine of this type, a generally known one is provided with a variable display device capable of variably displaying images of a plurality of types of identification information such as patterns. After the variable display device is variably started, the display result is derived and displayed by being stop-controlled, etc., and when the display result becomes a predetermined specific display mode (for example, 777), the player There was one that was configured to be controlled to a specific game state (for example, a big hit state) that is advantageous for the player.

In such a conventional gaming machine, based on two kinds of numerical data updated at a predetermined timing, it is determined whether or not a specific game state is generated, and display of identification information when the specific game state is generated. The selection decision of the result, and
There has been one that selects and determines the display result of the identification information when the specific game state is not occurring. The details are as follows.

In such a gaming machine, first numerical data creating means for creating numerical data used for selectively determining whether or not a specific gaming state has occurred, and a display result of identification information when the specific gaming state occurs It has a second numerical data creating means used for the selection decision or the selection decision of the display result of the identification information when the specific game state does not occur. The first and second numerical data creating means repeatedly perform regularly addition updating or subtracting updating of numerical data at a predetermined timing within a numerical range in which a lower limit value and an upper limit value are predetermined. And the numerical range was different. Within the range of the numerical data created by the first numerical data creating means, one judgment value (numerical data that is selectively decided to be controlled to the specific game state) is defined.

In the game, the numerical data of the first numerical data creating means is extracted on the basis of a predetermined timing such as a start winning for making the variable start of the variable display device variable,
When the extracted value matches the judgment value, the game state is controlled to a specific game state.

Further, display results of different identification information are individually set for each of the numerical data created by the second numerical data creating means. In the game, after the selection decision as to whether or not the specific game state occurs as described above, the numerical data of the second numerical data creating means is extracted, and the identification information when the specific game state occurs based on the extracted value. The selection decision of the display result of or the selection decision of the display result of the identification information when the specific game state is not occurring have been made.

[0007]

However, in the case of making a selective decision as to whether or not a specific game state has occurred using one of the above-mentioned judgment values, the numerical data is cyclic within a predetermined numerical range. Since there is a certain periodicity (regularity) in the timing at which the judgment value appears due to the updating of the numerical data of the first numerical data creating means, the randomness of the timing of occurrence of the specific game state is not sufficient. There wasn't. As a plan for improving the randomness of the occurrence timing of such a specific game state, the following plan can be considered.

As one proposal, the two types of numerical data creating means as described above are used, the range of the numerical data created by the first numerical data creating means is expanded, a plurality of judgment values are provided, and It is conceivable to make the numerical intervals between the judgment values non-uniform. By doing so, the timing at which the judgment value appears becomes irregular, and the randomness of the timing of occurrence of the specific game state improves. However,
In that case, since the range of the numerical data created by the first numerical data creating means is expanded as compared with the conventional case, a cycle in which the display result of the identification information that can be displayed when the specific game state occurs is displayed once. However, there was a drawback that the cycle became extremely long. The reason is that the presence or absence of the specific game state and the display result of the identification information are selected and determined based on the numerical data obtained by the two types of numerical data creating means. For example, since the range of the numerical data of the first numerical data creating means is extremely wide,
Since the cycle of the timing at which one judgment value among the plurality of judgment values repeatedly appears is extremely long, a specific game is performed based on the numerical data of the second numerical data creating means at each timing at which the one judgment value appears. Assuming that one display result at the time of state occurrence is obtained, in order to obtain a single display result of the identification information at the time of occurrence of a specific game state, a plurality of which may exist,
Such an extremely long cycle must be repeated for the number of such display results. The following plan is conceivable as a plan for eliminating such a period increase and improving the randomness of the occurrence timing of the specific game state described above.

The proposal is as follows. The presence or absence of the specific game state, the display result of the identification information when the specific game state occurs, and the display result of the identification information when the specific game state does not occur are based on the numerical data created by one kind of numerical data creating means. Select and decide. In that case, a hit determination value is provided by the number of display results of all the identification information that can be displayed when the specific game state occurs, and the specific game state can be generated with a certain probability corresponding to the number of the hit determination values. Set the numerical range of the numerical data creation means to. Furthermore, the presence or absence of the specific game state corresponding to all the numerical data within the range of the numerical data created by the numerical data creating means, and the display result of the identification information when the specific game state occurs (the numerical data is the judgment value (If there is) or a display result of identification information (when the numerical data is numerical data other than the judgment value) when the specific game state does not occur, a data table is prepared. Then, based on the extracted numerical data of the numerical data creating means, using such a data table, the presence or absence of the specific game state and the display mode of the identification information when the specific game state occurs, or the specific game state non The display mode of the identification information at the time of occurrence is simultaneously selected and determined. By doing so, the presence or absence of the occurrence of the specific game state and the display result of the identification information can be selected and determined by one numerical data creating means, so that by the first numerical data creating means having one hitting judgment value. All display results at the time of occurrence of the specific game state can be obtained at the same cycle as when the presence or absence of the specific game state is selectively determined and the display result of the identification information is determined by the numerical data of the second numerical data creating means. It will be possible.

However, in that case, the presence or absence of the specific game state, the display result of the identification information when the specific game state occurs, corresponding to all of the numerical data that can be created by the numerical data creating means, and It is necessary to have a data table in which data indicating the display mode of the identification information when the specific game state is not generated is integrated, and such a data table has an enormous amount of data. Therefore, in that case, it is necessary to use a data table having such an enormous amount of data and to perform processing for determining various selection decision items corresponding to the extracted numerical data. CP for game control when executing decision processing
There is a drawback that the processing load of U becomes extremely large.

The present invention has been conceived in view of such circumstances, and an object thereof is an amount of information used for selecting and deciding whether or not to control a specific game state and selecting and deciding a display mode of a variable display device. It is possible to prevent an increase in the number of CPUs, reduce the processing load on the CPU for game control, and further improve the randomness of the occurrence of a specific game state. That is.

Next, the game features of the pachinko gaming machine 34 will be described in more detail. When the special symbols that are variably displayed on the variable display unit of the variable display device 4 are stopped and displayed in a predetermined combination, a big hit occurs, but a high probability state (probability fluctuation state) is included in the combination of special symbols that is a big hit. (Also referred to as)) is included. This combination is particularly called a combination of probability variation symbols. When the game is in the high probability state, the probability that a big hit will occur is adjusted to be higher than in the normal state. In addition, the variable display 1
The probability that the variable display result of the ordinary symbol in 7 is a hit is also adjusted to be high.

In the pachinko gaming machine 34 shown in the present embodiment, a big hit occurs based on the combination of the stochastic fluctuation symbols, and after a predetermined number of repetition continuation controls are all completed, 1
After the probability change of the second time occurs, and then a big hit occurs, 2
The probability change of the second time occurs. If the big hit that occurred at the first or second probability fluctuation is due to the combination of probability fluctuation patterns, after the big hit, the first time, 2 again
The probability change of the second time occurs. That is, if a big hit due to the combination of probability fluctuation patterns, after the big hit,
At least until a big hit occurs twice, the high probability state is set in the second state, which is disadvantageous to the player who is not subjected to the repeated continuous control. If the combination of symbols that has been a big hit by the time the second probability fluctuation has occurred is not a combination of probability fluctuation symbols, the state returns to the state where no probability fluctuation has occurred, after the repetition continuation control accompanying the big hit has ended.

In the present embodiment, the probability that a big hit will occur as a probability change, and the probability that the variable display result of a normal symbol will be a hit are high, but the present invention is not limited to this, and either one of the probabilities Only the height may be increased. Further, even if the probability does not change at all, the time for variable display of the normal symbols may be shortened.

Further, a specific symbol called a "lucky number" is included in the symbols constituting the special symbol combination which is a big hit in the pachinko gaming machine 34 shown in the present embodiment. Normally, a prize ball acquired by the occurrence of a big hit must be temporarily exchanged for a prize or the like, so that the prize ball cannot be directly used for a game. However, when a big hit occurs with a lucky number, the acquired prize ball can be directly used for a game. Such a lucky number causes a big hit and shifts to a specific game state is called a lucky start. On the back surface of the game control board box provided on the back surface of the pachinko gaming machine 34, a probability setting switch (not shown here and shown in FIG. 3) including a key switch is provided. The probability setting switch variably sets the probability that the display result when the variable display device 4 is variable stopped is a combination of specific identification information, that is, the probability that a big hit occurs. Can be switched to the position. The probability can be changed by inserting a predetermined key into the probability setting switch and performing a switching operation, and the jackpot probability can be switched and set in two stages according to the number of times of this switching operation. The probability setting switch may be, for example, a slide switch, a push button switch, a snap switch, a push-pull switch, a rotary switch, a digital switch, or the like, instead of the key switch.

To do.

FIG. 6 is an explanatory diagram showing the types and contents of the random counters used in the pachinko gaming machine 34 in this embodiment. The random counter is a counter that counts random numbers used for the variable display control of the special symbol of the variable display device 4. In this embodiment, WCR
ND1, WC RND L, WC RND C, WCR
Five types of random counters, NDR and WC RND RCH, are used. The values of these random counters are read at a predetermined timing during a pachinko game, and the variable display (variable display) operation of the variable display device 4 is controlled based on the values. The reading process of the count value of the random counter is executed by the CPU 661 provided inside the basic circuit 66 in accordance with the control program of the control ROM 663.

WC RND1 is a random jack for determining big hits for determining in advance whether or not a big hit should be generated as a result of the variable display of the specific symbol on the variable display device 4, and at the same time, it was read out when making a big hit decision. It is a big hit symbol determination random counter for determining the big hit symbol in advance by the value of the random counter. WC RND
1 has two types of counter value ranges, setting 1 and setting 2, which are determined by the setting operation of the probability setting switch 780 described above. With setting 1, in the range of 0 to 5044,
The counter value is incremented by 1 every 0.002 seconds. And when it counts up to that upper limit,
It is configured to count from 0 again. Note that 0.002 seconds is an interval at which the control program is repeatedly executed in the basic circuit 66 in response to the periodic reset signal output from the periodic reset circuit 71.
In the case of setting 2, the counter value is incremented in the range of 0 to 5460 as in setting 1.

WC RND L, WC RND C, W
C RND R is a type of special symbol that is stopped and displayed in each of the left, center, and right symbol display areas when it is determined in advance that a non-big hit is to be made as a result of the variable display of the special symbol on the variable display device 4. Is a random counter. The count range of WC RND L is 0-12. The count range of WC RND C is 0 to 15. The count range of WC RNDR is 0-12. The counter value of the WC RNDL is incremented by one every 0.002 seconds. The WCRND C counter value is incremented by one every 0.002 seconds.
The remaining time of the interrupt processing operation 6 is counted up. The counter value of WC RND R is WC RND
When C is carried, it is incremented by one. W
C RND RCH is a random counter for determining the specified reach operation number for designating a predetermined reach operation from a plurality of reach operations. "Reach" here
This means that two hit symbols are stopped and displayed together on the variable display unit 5 of the variable display device 4, and a big hit occurs when one more hit symbol is stopped and displayed.
Among the types of reach determined by the WC RND RCH, there is also a procedure in the case of a final jackpot combination. The counter value of the WC RND RCH is incremented by one every 0.002 seconds, and is incremented by one by using the remaining time of the interrupt processing operation of the basic circuit 66.

FIG. 7 shows the random counter WC RND1.
6 is a flowchart showing a control procedure for determining in advance whether or not to generate a big hit depending on the value of. With reference to FIG. 7, it is determined whether the result of the variable display of the special symbol on the variable display device 4 is a big hit or something other than a big hit, and further, the left symbol which is stopped and displayed on the variable display part 5, the middle symbol. A procedure for determining the type of right symbol will be described.

FIG. 7 shows a flowchart in the case where the jackpot occurrence probability described above is set to the setting 1. If WC RND1 is a big hit judgment value (big hit value) set in a big hit table described later using FIG. 10, it is a big hit, and the big hit judgment value (big hit value)
If it is other than, it will be a jackpot. Note that the same determination is performed even in the high probability state.

When it is decided to make a big hit,
Using a jackpot table to be described later, based on the jackpot determination value (jackpot value), determine the type of jackpot symbol of the special symbol for generating a jackpot. On the other hand, if it is decided that it should be something other than a big hit (out), then WC
By determining the values of RND L, WC RND C, and WC RND R, the types of the left symbol, the middle symbol, and the right symbol to be stopped and displayed are respectively determined. In addition, in the case where the combination of the determined stop symbols is accidentally the combination which becomes the big hit in the case other than the big hit, WC RND
"1" is added to the value of C, and adjustment is made so that stop display is forcibly performed with a combination of missing symbols.

Even when the big hit occurrence probability is set to the setting 2, whether or not to make the big hit in the same procedure as the case of the setting 1, the kind of big hit symbol when the big hit is generated, and the big hit The type of the out-of-place symbol in the case of not generating is determined.

The probability that a big hit will occur in the normal state is set to 13/5044 in setting 1 and 13/5460 in setting 2. On the other hand, the probability that a big hit will occur in the high probability state (probability variation state) is set to 91/55044 in setting 1, and to 104/5460 in setting 2.

FIG. 8 is an operation explanatory view for explaining the generation operation of the high probability state (also referred to as the probability variation state). Here, the condition device shown in FIG. 8 is a ROM in the basic circuit 66.
It is configured by a game control program stored in 663, and when the specific game state (big hit state) is reached, the stopped state is switched to the operating state, and the operating state is maintained until the big hit control ends. If the display result of the variable display device 4 at the time of occurrence of this special game state is a combination of special symbols, the state is controlled to a high probability state in which the probability of occurrence of the subsequent big hit is improved. And
If a big hit occurs in the high probability state, the big hit control is started again and the condition device is activated. The display result of the variable display device 4 at the time of occurrence of the second big hit is
If it is a combination of special symbols that is a big hit, but is not a combination of stochastic fluctuation symbols, it will not be in a high probability state even if the second big hit control ends. In FIG. 8, the combination of special symbols is "1", "3", "5",
It is shown that it is a combination of stochastic fluctuation symbols that is in a high probability state if any one of "7" and "9" is selected. Then, the first and second high-probability states occur based on the occurrence of the big hit due to the combination of the probability variation symbols.

FIG. 9 shows a deviation symbol table in a table format in which the special symbols displayed on the variable display device 4 and the symbol positions corresponding to the respective values of WC RND L, C, and R are summarized. It is a figure. Such a deviation symbol table is an RO of the basic circuit 66 as a data table.
It is stored in M663.

Each of the left symbol displayed on the left side of the variable display unit 5 of the variable display device 4, the middle symbol displayed on the center, and the right symbol displayed on the right side is shown. The numbers shown on the left side of FIG. 9 are numbers representing the symbol positions, and correspond to the respective values of WC RND L, C, and R. Numbers of symbol positions from 00 to 15 are assigned to the symbols constituting the middle symbol. The middle symbol is composed of numeral symbols "1" to "9" and alphabet symbols "A" to "G". On the other hand, the symbols constituting the left symbol and the right symbol are 00
For the symbol positions from 1 to 12, "1" to
It is composed of a numeral design of "9" and an alphabet design of "A" to "D". These symbols are variable display section 5
In the display (variable display), then WCR
The symbols corresponding to the values of ND L, C, and R are stopped and displayed. As a result of the variable display, if the left symbol, the middle symbol, and the right symbol all stop at the same symbol, a big hit occurs.

FIG. 10 is a view showing the contents of a big hit table showing the relationship between the big hit determination value of WC RND1 and the big hit symbols in a tabular form. This big hit table is stored in the ROM 663 of the basic circuit 660 as a data table.

In FIG. 10, the jackpot judgment value at the normal time (when the probability is not changed), the jackpot judgment value at the time of probability fluctuation in the case of setting 1, and the jackpot judgment at the time of probability fluctuation in the case of setting 2 The relationship between the value and the big hit pattern (hit pattern) is shown.

The big hit judgment value is different between the setting 1 and the setting 2 when the probability is changed (when the probability is changed). That is, both the setting 1 and the setting 2 have the same jackpot determination value in the normal time, and the determination value is shown in the column of "normal time" in the drawing.

When the probability of setting 1 fluctuates, the value shown in the column of "probability change setting 1" in the figure is used as the jackpot determination value. In the case of probability change of setting 2, in addition to the jackpot judgment value shown in the column of "probability change setting 1" in the figure, the jackpot judgment value shown in the column of "setting 2" in the figure Used for judgment. That is, in a normal time (when the probability is not changing), the big hit occurrence probability is the same in both the setting 1 and the setting 2, and in the case of the probability changing, the setting 2 is more likely than the setting 1. It is set to increase the probability of big hits.

As described above, in the big hit table of FIG. 10, the data (big hit judgment value) used for judging whether or not the big hit has occurred is commonly used in the setting 1 and the setting 2 with respect to the big hit occurrence probability. Therefore, when the jackpot occurrence probability can be changed in a plurality of steps, it is possible to reduce the amount of data used for determining whether or not the jackpot is to be generated.

Further, in the big hit table of FIG. 10, the intervals (numerical values) at which the big hit determination values are arranged are set to be non-uniform. WC RND1 is from "0" to "504
Since it is a counter that counts up by 1 to 4 "or" 5460 ", by making the intervals of the big hit values non-uniform in this way, for example, the big hit determination values are arranged at equal intervals (temporal). The big hit table of FIG. 10 can improve the randomness of big hit occurrence compared to the ones.

Next, a symbol selection process for selecting a special symbol displayed on the variable display device 4 will be described. This symbol selection process is executed by the basic circuit 66.

FIG. 11 is a flow chart showing the processing procedure of the symbol selection processing. First, step S (hereinafter simply referred to as S
1), the value of WC RND1 is checked. This S1 is performed in response to the start winning of the ball. Next, in S2, it is determined whether or not the probability is currently changing. If it is determined in S2 that the probability fluctuation is not occurring, the process proceeds to S3, and after the portion of the normal jackpot table corresponding to the normal column of the jackpot table shown in FIG. move on. On the other hand, if it is determined in S2 that the probability change is in progress, the process proceeds to S4, and depending on the setting of the probability setting switch 78, "probability change time setting 1" or "probability change time setting 1" shown in FIG. After the probability variation big hit table corresponding to the column of "Setting 2" is referred to, the process proceeds to S5.

At S5, based on the jackpot table referred to at S3 or S4, the W checked at S1.
It is determined whether or not the value of CRND1 corresponds to the jackpot determination value (whether or not it is a jackpot). When it is determined in S5 that the jackpot is a big hit, the process proceeds to S7 and S
The jackpot pattern corresponding to the value of WC RND1 checked in 1 is determined using the jackpot table of FIG. 10, and the determined jackpot symbol is set as a stop symbol. As a result, the symbol set in S7 is stopped and displayed as a big hit symbol on the variable display device 4. After that, this symbol selection process ends.

On the other hand, if it is determined in S5 that the jackpot is not a big hit, the process proceeds to S6, in which the respective values of WCRND L, C, and R are checked. afterwards,
Proceed to S8, and check the WC RND L,
The symbols corresponding to the respective values of C and R are determined using the deviation symbol table shown in FIG. 9, and the determined symbol is set as a deviation stop symbol.

Next, in S9, it is judged whether or not the symbol set in S8 matches the big hit symbol. S
When it is determined by 9 that the coin does not match the big hit symbol, this symbol selection process ends. On the other hand, by S9,
If it is determined that it matches the big hit symbol, the process proceeds to S10, where the middle symbol of the symbols set in S8 is shifted by one symbol and set. As a result, the stop symbol is forcibly set to the detached symbol. After that, this symbol selection process ends.

Thus, in the symbol selection process, W
Based on the value of C RND1, selection determination of whether or not to generate a big hit, and selection determination of a big hit symbol when a big hit is generated. On the other hand, WC RND L,
On the basis of the respective values of C and R, the out-of-range design when a big hit is not generated is selected and determined.

As described above, by using two random counters and one data table each including one random counter and one data table, the presence / absence of a big hit and the big hit symbol and the outlying symbol are shared and selected. Since the determination is made, it is not necessary to use a data table having an extremely large amount of data, so that the amount of data (the number of data) of each data table used for determining the selection can be reduced. Then, the C of the basic circuit 66 for performing such a selection determination process is caused by suppressing the data amount of each data table to be small.
The load of the processing load on the PU 661 can be reduced.

Further, as shown in the big hit table of FIG. 10, a plurality of big hit judgment values are provided, and the big hit judgment values are generated by the random counter WC RND1 at intervals (numerical intervals) which are not uniform. It is possible to improve the randomness with respect to the related art.
Such improvement in randomness is because it is possible to provide a plurality of jackpot determination values by reducing the processing load of the CPU 661 of the basic circuit 66 as described above, and is derived by reducing such processing load. The effect is

As described above, in this pachinko gaming machine, it is possible to improve the randomness of the big hits without increasing the data amount of the data table for selection determination.

[Effect of a concrete example of means for solving the problem]
Regarding, regarding the selection decision whether or not to control to the specific game state, the selection determination of the display mode of the variable display device when it is determined to control to the specific game state, and the determination not to control to the specific game state are determined. In this case, the selection determination of the display mode of the variable display device is shared and selected by the two sets of numerical data creating means and the selection determining means. Therefore, 1
The amount of information used by one set of random number generating means and selection determining means can be reduced as compared with the case where all the selection determination is performed by one numerical data generating means and selection determining means. Further, by reducing the amount of information used for one selection decision in this way, it is possible to reduce the load of the processing load on the CPU for game control that makes such various selection decisions. Furthermore, since a set of numerical data creating means and a selection determining means can collectively make a selection decision as to whether or not to control to a specific game state and a display mode selection control at the time of controlling to a specific game state, If the numerical data for controlling the specific game state is randomly created, the randomness of occurrence of the specific game state is improved without increasing the amount of information used for such selection decision.
