Description

The present invention relates to a gaming machine that generates a special game state when a variable display game is executed by a variable display device based on a lottery result of a lottery means, and a result that is derived and displayed becomes a predetermined special display mode. .

2. Description of the Related Art Conventionally, for example, a pachinko gaming machine as a ball game machine has a display device (variable display device) capable of displaying a variable display game based on a plurality of identification information on a game board, and a start winning opening. When a game ball is won, a variation display game is known in which a plurality of identification information is variably displayed on the variation display device by display control in an effect control device.
Further, when a game ball wins again at the start winning opening while the variable display game is being performed, the start memory is sequentially added and stored, and after the variable display game is completed, the start memory is subtracted. At the same time, a variable display game corresponding to the start memory was played.

The variation display game is performed by variably displaying, for example, each of the left, middle, and right display areas formed on the variation display device, with a symbol sequence including a plurality of symbols including identification information as identification information. When a predetermined time has elapsed from the start of the variable display game, the variable display in each display area is stopped, for example, in the order of left, right, and middle, and a predetermined pattern is stopped and displayed to derive a result mode. ing.
The variable display in each display area is performed by updating and displaying the symbols sequentially, for example, according to the order in the symbol row. In addition, this result mode is already determined based on the random number extracted at the time of starting winning, for example, at the beginning of the variable display game, and the variable display of the plurality of display areas is the already determined result mode. Each symbol is controlled to stop so as to match.

Then, when the variable display game is over, each symbol that is stopped and displayed in each of the plurality of display areas has a predetermined special result mode (for example, “1,1,1”, “2,2” , 2 ”, etc.), a special game state (a big hit game state) is generated as a game value impartation, for example, a variable winning device provided on a game board To increase the interest by providing a chance that the player can acquire a large amount of game balls (game value) by operating the (big prize opening) and converting the opening members (opening and closing doors, etc.) to the open state It was.

By the way, in a conventional pachinko gaming machine, a setting operation unit (for example, by key operation) that can be set to any one of a plurality of types of jackpot probabilities is provided on the main board (game control device).
The setting operation unit for changing the jackpot probability can be changed only when the power is turned on. When the jackpot probability is increased (for example, 1/250), a considerable jackpot is expected during business hours of the day. As a result, the player can have an opportunity to earn a large profit. Conversely, when the big hit probability is lowered (for example, 1/400), the profit for the player can be set lower. As a result, at a gaming store, for example, it is possible to perform a sharp business by changing settings or adjusting nails every day or every plurality of days at each gaming machine.

Prior art documents showing such a configuration example include the following.

FIG. 4 is a flowchart showing a control procedure of a main control process including an initialization process of the game control apparatus executed by turning on the power switch SW2. The initialization process is a process that is performed after the power is turned on by the power switch SW2 and the input of the reset signal is changed and the operation of the CPU 211a is started.
When the process is started, all output ports are initially set in step S100, and then the process proceeds to step S101 to determine whether or not the RAM initialization switch SW1 is turned on.

If it is determined in step S101 that the RAM initialization switch SW1 is not turned on, the process proceeds to step S102 to determine whether normal power is restored, that is, the backed up data stored in the RAM 211c is normal. It is determined whether or not. If it is determined that the power is normal, the process proceeds to step S103 to perform a power recovery process for returning to the power-off state, and execute from a predetermined process at the time of power-off in step S109, which is a normal process. To do.
As a result, when the power switch SW2 is turned on while the RAM initialization switch SW1 is not pressed, when it is determined that the backed up data in the RAM 211c is normal, the power is shut off and the state is restored.

If the power switch SW1 is turned on when the RAM initialization switch SW1 is not pressed, the process proceeds to step S104 when it is determined that the data in the RAM 211c is not normal.
If the store clerk of the game store presses the RAM initialization switch SW1 with one hand and turns on the power switch SW2 with the other hand, the process proceeds to step S104.

In step S104, an initial setting value is set in the stack pointer, and then the process proceeds to step S105, where the predetermined storage area of the RAM 211c is cleared and the initial setting is performed. In this initial setting, the game control information other than the probability setting information is unconditionally set to the initial setting. The probability setting information changes its value based on a setting change request operation described later.

Next, the process proceeds to step S106, and a command for notifying that the predetermined storage area of the RAM 211c has been initialized is transmitted to the effect control device 4000 as the sub control device. Thereby, it is possible to confirm that the predetermined storage area of the RAM 211c has been initialized by turning on the lamp or LED or outputting a predetermined sound. In this embodiment, the predetermined storage area of the RAM 211c is not initialized unless the power switch SW2 is pressed while the RAM initialization switch SW1 is pressed. Even if the RAM initialization switch SW1 and the power switch SW2 are turned on at the same time, the notification is performed by turning on the lamp or LED or outputting a predetermined sound as described above. There is an effect that it is easy to find an action.

Next, after permitting an interrupt in step S107, the process proceeds to step S108 to determine whether or not the probability setting is confirmed, that is, in this embodiment, the probability setting has been confirmed in the timer interrupt processing probability setting control process described later. Then, the process proceeds to step S109, and various random number update processes, which are normal processes, are performed.
In the main control process, after the initialization process is executed, various random number update processes, which are normal processes, are repeatedly executed while the power is on.

Next, the processing procedure of the timer interrupt process will be described with reference to the flowchart of FIG. This timer interrupt process is executed every 4 ms during execution of the main control process.
When this process is started, first, in step S200, the register is saved and the process proceeds to step S201. After the input process is performed to monitor whether the switch read process and the input are confirmed, the process proceeds to step S202.

In step S202, output processing is performed, and external information output, solenoid output, and gaming machine error status signal are output to the output port. Next, the process proceeds to step S203, and a probability setting control process for changing a probability setting or the like is executed. Details of the probability setting control process will be described later.

Next, the process proceeds to step S204, and it is determined whether or not the probability setting in the probability setting control process is confirmed. If it is determined that it has not been confirmed, the process jumps to step S213 to restore the register, and then returns to the main control process.

On the other hand, if it is determined that the probability setting has been confirmed, the process proceeds to step S205, where command transmission processing is executed, and display command transmission, discharge command, voice command, lamp command editing and transmission are executed. The process proceeds to step S206.

In step S206, a random number update process is executed to update the jackpot random number, jackpot symbol random number, random number per symbol, left symbol generated random number, middle symbol generated random number, right symbol generated random number, stop symbol pattern random number, fluctuation pattern random number Then, the process proceeds to step S207. Note that the big hit random number is updated by +1 every time the timer interrupt process is executed, and the random number generation range (for example, 1 in the case of setting 1) corresponding to the control value determined in the probability setting described above. The value is updated in the range of ~ 250. That is, it is updated by +1 up to the upper limit value of the random number, and when it reaches the upper limit value, it is updated again from 1 by +1.

In step S207, the big hit initial value random number update process is executed to update the big hit initial value random number. Note that the big hit random number in step S206 is obtained as the initial value of the update by acquiring the big hit initial value random number at a specific timing.

Next, the process proceeds to step S208, and an error monitoring process is executed. Specifically, prize ball detection switch detection error monitoring processing and prize ball payout excessive error monitoring processing are performed.

Subsequently, the process proceeds to step S209 to perform switch monitoring processing. The switches monitored in this process are, for example, a start opening switch for taking in a big hit random number or a big hit design random number, a gate switch for taking in a random number per ordinary figure, each winning opening switch, a V switch, a count switch, and the like. In addition, taking in the big hit random number here is the lottery of the random number value.

Next, the special game process is executed in step S210, the ordinary game process is executed in step S211, the external information editing process is executed in step S212, and then the process proceeds to step S213. After the register is restored, the process proceeds to the main process. Return.
In addition, when the variable display game is generally controlled in the special figure game processing here and the variable display game start condition is satisfied, if there is a start winning memory, the stored big hit random number value is determined in advance. The lottery result is set based on the determined determination value, and the variable display game is executed based on the result.

Next, the processing procedure of the above probability setting control processing will be described with reference to the flowchart of FIG.
In this process, first, in step S300, it is determined whether or not to execute this process for the first time after the initial setting at the time of power-on. If YES is determined in step S300 (determined to be the first execution when initial setting is performed), the process proceeds to step S301, and the probability setting is not yet determined, and the process proceeds to step S304. . In step S304, it is determined whether or not the switch SW-X is turned on. That is, it is determined whether or not the key is turned counterclockwise from the reference position (neutral state). Here, the switch SW-X at this time rotates the key before the power-on operation of the power switch SW2, or rotates the key almost simultaneously with the power-on operation of the power switch SW2, thereby this step S304. The turn-on state of the switch SW-X is an operation for requesting a probability setting when the power is turned on. Therefore, the key (switch SW-X) has a setting control request operating means. Constitute. When the switch SW-X is on, that is, when there is a request operation signal from the setting control request operation means, the process proceeds to step S305. By shifting to step S305, the probability setting can be changed (setting control is enabled), and in step S305, the previous probability setting information that has been backed up is acquired. Next, the process proceeds to step S307, where a timer initial value used when setting control is completed is set. Then, the process proceeds to step S308, the setting of outputting the probability setting value acquired in step S305 is performed on the information display, this process is terminated, and the process returns to the process of FIG.

When this probability setting control process is executed again in the timer interruption process, it is determined as NO in step S300, and it is determined whether or not the probability setting is confirmed by moving to step S302. In step S302, in the case of the probability setting state, it is determined NO because the probability setting has not been confirmed yet, the process proceeds to step S309, and when the probability setting is confirmed, that is, when the probability has been set. It determines with YES and transfers to step S303.

In step S309, it is determined whether or not the switch SW-Y of the key switch mechanism K is turned on (that is, whether or not an edge portion is output in the signal).
If it is determined that the switch SW-Y is turned on (the key is rotated clockwise), the process proceeds to step S306, the probability setting value is incremented by +1, and the process proceeds to step S307. Here, the probability setting value is selected from, for example, three levels of setting value 1 (probability 1/250), setting value 2 (probability 1/350), and setting value 3 (probability 1/400), and step S306. Is updated every time (i.e., each time the key is rotated clockwise and the switch SW-Y is turned on), for example, 1 → 2 → 3 → 1 →.

If it is determined in step S309 that the switch SW-Y is not turned on, it is determined in step S310 whether the logical product of the switch SW-X and the switch SW-Y is “0”, that is, the key switch mechanism K. It is determined whether or not the key is in a neutral state. If YES is determined, the process proceeds to step S307 and subsequent steps. If NO is determined, the process proceeds to step S311.

In step S311, it is determined whether or not the switch SW-X and the switch SW-Y are maintained in the OFF state, that is, whether the key is maintained in the neutral state. If NO is determined, the process proceeds to step S308. When it determines with YES, it transfers to step S312 and decrements the control timer by -1 and progresses to step S313. That is, when the key is maintained in the neutral state, the timer is subtracted, and when the key is operated (operation in the clockwise direction, operation to the neutral position), the timer is set again.

In step S313, it is determined whether or not the control timer has timed out. If it is determined as NO, the process returns to the above-described process of FIG. 5 and the process is continued. If it is determined as YES, step S313 is performed. After proceeding to S314 and setting the probability setting confirmation, the process proceeds to step S315.

In step S315, the random number upper limit value corresponding to the probability setting value is saved. That is, here, the upper limit of the random number generation range according to the determined probability setting value is stored, the upper limit value of the big hit random number is determined with the value stored here as the upper limit value, and corresponding to the update process of the big hit random number described above Update processing is executed. Thereafter, the process proceeds to step S316, the extinction data of the information display H is output, and the process returns to the above-described process of FIG. The above is the process related to the probability setting value setting control.

On the other hand, if step S300 is YES and the switch SW-X is not turned on in step S304, that is, if there is no request operation signal from the setting control request operation means immediately after the initial setting at power-on, the process proceeds to step S317. In step S317, probability setting initial information is acquired. Here, the probability setting initial information is the probability setting information that is set when the RAM initialization switch is turned on when the power is turned on or when the power is not restored normally and when no setting control request is made. In the case where there are a plurality of probability setting values, a setting value with which the jackpot probability is the lowest is determined in advance. Then, the process proceeds to step S314, where the probability setting confirmation is set, and in step S315, the random number upper limit value for the probability setting value is saved. That is, here, the upper limit of the random number generation range according to the determined probability setting value is stored, the upper limit value of the big hit random number is determined with the value stored here as the upper limit value, and corresponding to the update process of the big hit random number described above Update processing is executed. Finally, in step S316, the data display extinguishing data is output and the process is terminated. The above is the process related to the special setting control of the probability setting value.

On the other hand, if NO is determined in step S300 (that is, it is determined to be executed for the second time after the initial setting), the process proceeds to step S302 to determine whether or not the probability setting is confirmed. If it is determined here that the probability has already been set, since the probability has already been set, the process jumps to step S316, outputs the extinction data of the information display H, and returns to the above-described processing of FIG. If it is determined in step S303 that the switch SW-X of the key switch mechanism K is turned on (that is, the key is turned counterclockwise), the process jumps to step S308 to jump to the information display. Display data corresponding to the probability setting value is output to H (for example, the current setting value when the probability setting value is selected from the three levels 1 to 3), and then the processing returns to the above-described processing of FIG. To do.

As described above, the key switch mechanism K is used by using the key possessed by the store clerk in the game store at the time of power-on and after the initial setting (when the RAM initialization switch SW is turned on). Since the probability cannot be changed unless the switch SW-X or the switch SW-Y is operated, it is possible to prevent a situation where an unauthorized person intentionally changes the set value.
Further, since the set value is displayed on the status indicator H, it is possible to check the setting contents and to know whether or not the setting has been made correctly.

Here, referring to the table of FIG. 7, when a power supply is turned on, a setting change request operation is performed (when switch SW-X is turned on) or not (when switch SW-X is off). ) And the presence / absence of operation of the RAM initialization switch SW1.

First, when the RAM initialization switch SW1 is turned on or when the power is turned on when the contents of the RAM 211c are not held (initial time), and there is no setting change request operation, the probability setting value is an initial value (minimum probability). And In this case, all data other than the probability setting value are cleared in the storage area of the RAM 211c.

In addition, even if there is a setting change request operation in the same state, the setting is updated to a new setting value that has been changed (operation of the switch SW-Y). However, all data other than the set value is cleared in the storage area of the RAM 211c.

When the power is turned on (restored) while the contents of the RAM 211c are held and there is no setting change request operation, the setting value is set to the setting value stored last time. Data other than the set value is also kept at the previous value.

In the same state, if there is a setting change request operation, the setting value cannot be changed, and the setting value is the setting value stored last time. Data other than the set value is also kept at the previous value.

In this way, whether or not the setting value can be changed changes depending on the state when the power is turned on, and even if an unauthorized person intentionally changes the probability setting value, it cannot be easily operated. Therefore, it is possible to prevent the occurrence of fraud. Next, with reference to FIGS. 8 and 9, an embodiment in which the history of probability setting values can be displayed will be described.

In the case of such a configuration, in FIG. 2, instead of the information display H composed of the segment display arranged on the back of the game control device 2000, as shown in FIG. An information display unit composed of a plurality of LEDs is provided.
In the example of FIG. 8A, three LED rows 800 corresponding to the set values 1, 2, and 3 are provided over six stages. In addition, a LED larger than the others is arranged at the bottom to display the current set value. The other five levels display the setting values from one day before to five days in order from the bottom. In this embodiment, when the power is turned off or when the power is turned on, the set value at that time is stored, and the value is stored for 5 days, for example, and displayed.

In the example of FIG. 8B, three LED rows 801 corresponding to the setting values 1, 2, and 3 are provided in three stages. In addition, a LED larger than the others is arranged at the bottom to display the current set value. In addition, the other two levels display the previous and previous set values in order from the bottom. In this embodiment, every time the setting is changed, the setting values up to that point are stored (for example, stored twice before) and displayed.
The flowchart of FIG. 9 showing the processing procedure of the probability setting control process when displaying the history of the probability setting values as shown in FIG. 8B is similar to the flowchart of FIG.

Differences between the flowcharts of FIGS. 9 and 6 will be described.
Steps S400 to S416 except for step S420 and step S421 in the process procedure of FIG. 9 are the same as the process steps S300 to S316 of the flowchart of the probability setting control process shown in FIG.

In the flowchart of FIG. 9, after the probability setting is set as uncertain in step S401, the process proceeds to step S420, and the probability setting storage is shifted and updated. If it is determined in step S404 that the switch SW-X is turned on, the process proceeds to step S405. After obtaining probability setting information, the process proceeds to step S421, and the information display unit corresponds to the setting history. Display data is output.
As a result, the history every time the probability setting is changed can be displayed as shown in FIG. With this history display, it is possible to grasp the setting status of the gaming machine, which can be used as sales information, and confirm whether there has been an unauthorized setting change unintended by the amusement store before the setting change. It is also possible.
