[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko gaming machine.
[0002]
[Prior art]
Conventionally, a pachinko gaming machine in which the symbol of the display unit provided on the game board fluctuates and a predetermined jackpot symbol is stopped and displayed when a ball is won at the start winning opening, so called Seven machines are well known. With regard to such a pachinko machine, it is configured so that a variable winning opening such as an attacker can be opened by winning the jackpot in the lottery process executed when a ball wins the start winning opening. There are many. And, it is possible to get a lot of balls easily by letting open attackers win balls one after another.
[0003]
[Problems to be solved by the invention]
However, looking back, it is clear that the pachinko machines as described above have little room for intervention by the player's judgment. For this reason, any player who is familiar with the mechanism that generates jackpots should not seem to be uniform.
[0004]
In view of the above, an object of the present invention is to provide a pachinko gaming machine in which uniformity is reduced by enhancing the intervention of judgment made by a player.
[0005]
[Means for solving the problems and actions / effects]
In order to solve the above-described problems, the present invention provides a pachinko gaming machine in which a display unit is arranged on a game board, and a symbol is variably displayed on the display unit according to establishment of a predetermined start condition. The lottery means for executing a lottery process for extracting one symbol from a symbol group composed of a plurality of types of symbols prepared in advance, and a plurality of predetermined numbers after the lottery process is executed. The selection input means for the player to select and input one winning symbol from the winning symbol group consisting of the types of winning symbols, the symbol extracted by the lottery process, and the winning symbol selected and input by the player match. Design determination means for determining whether or not In the symbol determination means, If you receive a determination that both symbols match Jackpot processing to open the big winning opening which is a variable winning opening intermittently If you receive a decision that they do not match, Jackpot processing The first game that is determined and displayed after the symbols are variably displayed on the display unit so that the player can identify the type of symbols extracted in the lottery process before the player performs input and the input that the player performs. A game mode control means for selectively presenting either the mode or the second game mode that is fixedly displayed after the symbols are variably displayed on the display unit so that the player cannot identify the type of the symbols. It is characterized by having.
[0006]
In the present invention, a lottery process for selecting a symbol is first executed in response to the establishment of a predetermined start condition (for example, a ball wins a start winning opening). This lottery process is not directly related to whether or not a win is generated, and is merely a lottery for selecting one symbol. After the lottery process is executed, the player uses the selection input means to input one winning symbol from the winning symbol group. Then, it is determined whether or not the symbol selected by the lottery means included in the pachinko gaming machine matches the winning symbol selected and input by the player, and when both symbols match, a predetermined winning process is executed. In other words, the player's judgment means to predict which symbol will be hit and feed it back to the pachinko machine side. However, it is necessary to make such a prediction when the pachinko gaming machine is in the second gaming mode, and when the gaming machine is in the first gaming mode, the symbols extracted by the lottery process described above are not used. Since it is notified beforehand, there is no need for the player to make a prediction. Therefore, in the first game mode, it is possible to acquire a substantial hit relatively easily. As described above, the pachinko gaming machine of the present invention is configured such that the player's judgment is directly involved in the actual winning of the win, so that the mechanism of occurrence of the winning / losing is prevented from being uniform. It can be said that.
[0007]
Specifically, the symbol group that is the symbol extraction target of the lottery means included in the pachinko gaming machine can be composed of a plurality of types of winning symbols and one or a plurality of types of outlier symbols. The selection input means preferably adopts one that changes so that the player can arbitrarily select and input a winning symbol when the symbol extracted by the lottery process performed by the lottery means corresponds to the winning symbol. Is done.
[0008]
In this way, it is not necessary for the player to select and input a desired winning symbol every time a predetermined start condition is established and a symbol is extracted. That is, it is possible to moderately adjust the influence of the player's judgment on the game. Specifically, for example, it can be configured such that an input using the selection input means is possible only when the lottery means extracts the tactile symbol.
[0009]
In a more preferred aspect, the selection input means includes a variable winning opening whose degree of difficulty of winning a ball changes according to the opening / closing operation, and a winning detection unit provided corresponding to the variable winning opening. be able to. In that case, it is preferable to further provide a control means for controlling an actuator for changing the degree of opening and closing of the variable winning opening and controlling whether or not the player can select and input a winning symbol.
[0010]
In other words, the act of putting a ball into the variable winning opening as the selection input means is also used for the act of the player selecting and inputting a symbol. With this configuration, there is no need to provide selection input means on the frame of the pachinko gaming machine, which contributes to cost reduction. In addition, since the player only needs to perform a simple act of putting a ball into the open variable winning opening, the game does not become too complicated.
[0011]
Specifically, when a symbol extracted by the lottery means corresponds to a winning symbol, a plurality of predetermined winning symbols or symbols individually corresponding to the plurality of winning symbols are sequentially switched and displayed on the display unit. A switching display means can be further provided. In this case, the player receives the winning symbol corresponding to the winning symbol or symbol displayed on the display unit when the winning detection signal transmitted from the winning detection unit is acquired in response to the ball winning in the variable winning slot. The above-described symbol determination means may be designed so that the symbol is recognized as the winning symbol selected and input.
[0012]
In this way, the player can perform a ball launching operation so that a ball is awarded to the variable winning opening at a timing when a desired winning symbol (or symbol) is displayed while looking at the display unit.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic front view of a pachinko gaming machine 1 which is an embodiment of the gaming machine of the present invention. The pachinko gaming machine 1 has a front glass door 5 attached to the underframe and a game board 3 that is arranged inside the underframe and is covered by the glass door 5. Below the game board 3, a ball supply tray 6 is provided. Balls (game balls) prepared in the ball supply tray 6 are launched toward the game board 3 by a ball launching mechanism including a handle 7. Since the game board 3 has a large number of nails, balls fired toward the game board 3 fall while being hit by the nails.
[0014]
The game board 3 is provided with a display unit 11 near the center thereof. The display unit 11 can be configured by a liquid crystal display device, for example. A start chucker 17 (start winning a prize opening) is arranged below the display unit 11. When a ball enters the start chucker 17, a winning is detected by a detection unit (detection switch) provided in a form corresponding to the start chucker 17. When it is detected that a ball is won in the start chucker 17, the change of the symbol is started on the display unit 11, the change is stopped after a predetermined time has elapsed, and the symbol is confirmed and displayed.
[0015]
Electric tulips 20 and 21 (hereinafter also simply referred to as electric chews) are arranged on the left and right sides of the display unit 11. The electric chews 20 and 21 are configured as variable winning openings in which the difficulty of winning a ball changes according to the opening / closing operation. The electric chews 20 and 21 can be configured such that the balls do not win when closed, or can have some chance of winning. Below the start chuck 17, an attacker 22 (a big prize opening) is arranged. The attacker 22 is also configured as a variable prize opening similar to the above. Further, below the start chucker 17, an out port 15 for collecting balls is provided.
[0016]
Next, FIG. 2 is a block diagram showing a configuration of the control device 200 of the pachinko gaming machine 1. As shown in FIG. 2, the control device 200 of the pachinko gaming machine 1 includes a main control board 100 (main control part), a display control board 105 (display control part), a voice control board 106 (voice control part), and a lamp control board. 107 (a lamp control unit), a payout control board 108 (a payout control part), and a launch control board 109 (a launch control part), which are arranged on the back side of the game board 3. Each board is generally provided with a microcomputer, which is omitted in FIG.
[0017]
The main control board 100 includes a CPU 50 as an arithmetic device, a ROM 51 storing a program and a lottery determination table, a work RAM 52, and an input / output port 53. These devices are connected to each other by a bus not shown in the figure. Of course, the main control board 100 includes well-known configurations such as a switch circuit, a solenoid circuit, a power supply circuit, and a reset circuit, although not shown.
[0018]
Winning detection units 32 to 35 are provided in a form corresponding to each of the electric chews 20 and 21, the attacker 22 and the start chucker 17 shown in FIG. Such winning detection units 32 to 35 are configured by optical sensors, for example, and output a ball winning detection signal to the main control board 100. In addition, the electro-chutes solenoids 37 and 38 and the attacker solenoid 39 are controlled to be switched between excitation and de-excitation by the main control board 100 (specifically, the CPU 50) via a solenoid circuit (not shown). 21 and the attacker 22 are opened and closed individually. Of course, a motor may be used instead of the solenoid.
[0019]
The display control board 105 displays an image on the display unit 11 (display device) in accordance with a display control signal input from the main control board 100. The audio control board 106 controls the amplifier in accordance with the input audio control signal and causes the speaker 12 to output audio. The lamp control board 107 controls blinking of the lamp 13 in accordance with the input lamp control signal. The payout control board 108 controls the payout device 14 according to the input prize ball signal. As a result, a predetermined amount of prize balls is paid out to the player. In response to the player operating the handle 7 (operation unit), the launch control board 109 activates the launch device 16 provided corresponding to the handle 7.
[0020]
Now, the pachinko gaming machine 1 of the present invention is configured to selectively present two game modes having different symbol variations when a ball wins the start chucker 17. One is an AT mode (first game mode) in which a two-digit number repeats scrolling and stopping, and the other is a normal mode (second game mode) in which a symbol different from the number repeats scrolling and stopping. FIG. 3 is a diagram for explaining a variation display mode in each of the game modes.
[0021]
FIG. 3A shows the symbol variation mode in the AT mode, and FIG. 3B shows the symbol variation mode in the normal mode. As shown in FIG. 3A, in the AT mode, a pair of integer columns from 0 to 9 is arranged, and each column is scrolled individually. After a predetermined time has elapsed, the scrolling is stopped and two digits are displayed. Control is performed so that the value (design) is confirmed and displayed. On the other hand, as shown in FIG. 3 (b), in the normal mode, a pair of symbol sequences represented by two types of symbols different from the AT mode, specifically, “o” and “x” are arranged. And each column is controlled to scroll individually. According to this, there are four types of symbols displayed when scrolling is stopped.
[0022]
However, when a ball wins the start chucker 17, the main control board 100 executes a lottery process common to both the AT mode and the normal mode. The difference lies in whether the symbol type determined in the lottery process is fixedly displayed so that the player can identify it or not. The normal mode is a game mode in which symbols are masked.
[0023]
In the main control board 100, a predetermined lottery process is triggered when a ball is won in the start chucker 17, specifically when a winning detection signal is input from the start chucker winning detection unit 34 (a predetermined condition is satisfied). Is executed by the CPU 50. The lottery process is a process for extracting one symbol from a symbol group composed of a plurality of types of symbols prepared in advance. Specifically, for example, a counter that represents one of two-digit integer values from “00” to “99” and that is incremented by +1 each time the CPU 50 is reset is provided in the RAM 52, and a start chucker winning detection unit The counter value can be read into the CPU 50 at the timing when the CPU 50 obtains the winning detection signal from 34. According to this, one of two-digit integer values from “00” to “99” is acquired according to the timing at which the ball is won in the start chucker 17. 100 kinds of two-digit integer values constitute the above-described symbol group, and are values that directly or indirectly indicate a symbol that is fixedly displayed when the display unit 11 stops changing. The value (design) extracted here is stored in a predetermined area of the RAM 52. Note that the reset period of the CPU 50 is designed to be, for example, about 2 msec, and a technique related to this is well known, and is omitted here.
[0024]
In addition, the pachinko gaming machine 1 is a selection for the player to arbitrarily select and input one winning symbol from a winning symbol group consisting of a plurality of predetermined winning symbols after the lottery process is completed. The CPU 50 of the main control board 100 includes an input unit, and the symbol determination unit for determining whether the symbol extracted by the lottery process described above matches the winning symbol selected and input by the player. In response to this determination, it functions as a hit generating means for executing a predetermined hit process. In the present embodiment, the predetermined hit process is a jackpot process that intermittently opens the attacker 22. In short, a jackpot is generated only when the symbol extracted by the lottery process executed when the ball is won in the start chucker 17 matches the winning symbol arbitrarily selected by the player and input to the control device 200. ing. The above determination is performed by the CPU 50 which is a symbol determination means.
[0025]
As the selection input means as described above, when the symbol extracted by the lottery process performed by the CPU 50 corresponds to the winning symbol, one that changes so that the player can arbitrarily select and input the winning symbol is adopted. it can. Specifically, the electric tulips 20 and 21 that are opened after the lottery process is finished and after the display unit 11 stops scrolling and the symbols are fixedly displayed, are provided in a form corresponding to them individually. The winning detection units 32 and 33 can be suitably employed as selection input means.
[0026]
The electric chus 20 and 21 open and close when the excitation / non-excitation of the electric chus solenoids 37 and 38 is switched, respectively. Therefore, as a result of controlling the electronic choke solenoids 37 and 38 (actuators) for changing the degree of opening and closing of the electric chews 20 and 21 by the CPU 50 as their control means, the player selects and inputs the winning symbol. Whether to allow or not to be controlled is controlled.
[0027]
The electric Chus 20 and 21 are configured to be opened only when a slot (specific value) such as “00” is extracted from the 100 kinds of values in the lottery process described above. can do. That is, a symbol group represented by 100 kinds of integer values from “00” to “99” includes a plurality of types of hit symbols (grooves: specific symbols) and one or more types of outlier symbols (grooves). Except).
[0028]
As described above, in the AT mode, the display control signal (from the CPU 50 of the main control board 100 to the display control board 105 is displayed so that the symbols selected in the lottery process are directly displayed when the scroll of the display unit 11 is stopped. Left symbol designation signal and right symbol designation signal) are output. In the normal mode, when the symbol selected in the lottery process is a specific symbol (groove), the main control is performed so that the winning symbol represented by “XX” in FIG. When a display control signal (left symbol designation signal and right symbol designation signal) is output from the CPU 50 of the substrate 100 to the display control substrate 105 and the symbol selected in the lottery process is other than the specific symbol, 1 is selected from a plurality of lost symbols. Display control signals (left symbol designation signal and right symbol designation signal) are output from the CPU 50 of the main control board 100 to the display control board 105 so that the two lost symbols are selected and displayed. It should be noted that whether the game mode is changed in the AT mode or the normal mode is determined based on the CPU 50 that is the game mode control means reading information relating to the game mode stored in the RAM 52.
[0029]
Thus, the CPU 50 as the game mode control means displays the symbols extracted in the lottery process on the display unit 11 in the AT mode (first game mode), while the lottery process in the normal mode (second game mode). A symbol (a combination of “◯” and “x”) that indirectly indicates the symbol extracted in step (b) is displayed on the display unit 11. Thereby, a difference can be given to the player's superiority in each mode.
[0030]
Next, FIG. 4 shows a display example of the display unit 11 in the normal mode. When the scrolling is stopped and the winning symbol is confirmed and displayed (screen generated per hit (1)), the screen is switched to the symbol selecting screen (2). Similarly, when a winning symbol (groove) is displayed in the AT mode, the screen is switched to the symbol selection screen (2). As shown in the example of the symbol selection screen, a plurality of predetermined winning symbols (hit numbers) are sequentially switched and displayed on the display unit 11. Further, instead of directly displaying the winning symbol, a symbol (corresponding) individually corresponding to the winning symbol may be displayed. Then, when the CPU 50 of the main control board 100 acquires the winning detection signals output from the respective electric chew winning detection units 32 and 33 in response to the balls winning in the electric chews 20 and 21, the CPU 50 Then, the winning symbol corresponding to the winning symbol or symbol displayed on the display unit 11 at that time is recognized as one winning symbol selected and input by the player.
[0031]
In the normal mode, the player cannot know the symbols extracted by the lottery process, but in the AT mode, the extracted symbols are displayed on the screen where the winning hit is (1). Therefore, it is only necessary to make the electric chews 20 and 21 win a ball at the timing when the winning symbol (winning number) is displayed on the symbol selection screen (2). In the present embodiment, the history of winning symbols extracted in the past is displayed almost simultaneously with the opening of the electric chews 20 and 21 regardless of the game mode. It is also possible to measure the timing at which the electric chews 20 and 21 win a ball with reference to.
[0032]
FIG. 5 is a diagram for explaining the types of winning symbols that are selected and input in response to the winning of balls on the electric chews 20 and 21 together with the switching cycle of the selection input screen. The CPU 50 functioning as a switching display means for sequentially switching and displaying the selection input screen outputs a control signal for stopping the scrolling (fluctuation) of the display unit 11 to the display control board 105, and then the symbol that is confirmed and displayed is the symbol ( In the case of the grommet), a control signal for displaying the selection display screen shown in FIG. 4 is output to the display control board 105. Then, for example, a display switching control signal is output so that the selection display screen is switched every 3 seconds. Thereby, the selectable symbols displayed on the display unit 11 are sequentially switched. The switching period (about 3 seconds in the present embodiment) may be counted by a counter (timer) provided in the RAM 52, for example.
[0033]
The selectable symbol information indicating what the selectable symbol is displayed on the display unit 11 or highlighted is stored in a predetermined area of the RAM 52. That is, although not shown in the explanatory diagram of FIG. 5, the CPU 50 rewrites the selectable symbol information stored in the RAM 52 every time a display switching signal is output.
[0034]
When a winning detection signal is input from the electric chew winning detection units 32 and 33 to the CPU 50, based on the input timing, the CPU 50 reads the RAM 52 to acquire selectable symbol information, and cancels the selection screen switching control described above. To do. Then, it is determined whether or not the winning symbol indicated by the selectable symbol information matches the winning symbol extracted in the aforementioned lottery process. As a result, when the winning symbol extracted in the lottery process matches the winning symbol selected and input by the player, the screen is switched to the selection success screen as shown by (4) in FIG. In the case of (3), a selection failure screen (3) is displayed. As described above, the result of the determination by the symbol determination means (CPU 50) is displayed on the display unit 11, so that the player can easily know whether or not the timing when the ball is put in the electric chews 20 and 21 is appropriate.
[0035]
Next, FIG. 6 is a flowchart showing processing executed in the main control board 100. Each process of S1-S4 is performed in this order. Specifically, FIG. 7 is a flowchart showing the start winning process (S1). When a ball wins the start chucker 17 and a winning detection signal is input from the start chucker winning detection unit 34 to the main control board 100 (YES in the determination of S101), in the subsequent step S102, the hold counter = 4, that is, It is determined whether the holding ball is full. When the holding counter is not 4, the symbol lottery process is performed as described above to extract one symbol (S103). The extracted symbols are stored in the RAM 52 (S104: symbol information storage process). Thereafter, a hold counter increment process (S105) and a hold number display update process (S106) are performed.
[0036]
Next, FIG. 8 is a flowchart showing the symbol variation process (S2). Before the symbol fluctuation control signal is output, it is determined whether or not the winning flag or jackpot flag is ON (S201). In S202, the symbols extracted by the lottery process are read from the RAM 52. Then, a decrement process of the hold counter (S203) and an update process of the hold number display (S204) are performed. Subsequently, it is determined whether or not the AT flag is turned on in response to reading of a predetermined storage area of the RAM 52 (S205). In the case of YES, a display control signal is output so that the screen is scrolled in the AT mode shown in FIG. 3A, and the symbol is fixedly displayed (S206). In the case of NO, a display control signal is output so that the screen scrolls in the normal mode shown in FIG. 3B, and the symbol is fixedly displayed (S207). Then, in S208, it is determined whether or not the winning symbol is stopped, and the winning flag is turned ON only when the answer is YES (S209).
[0037]
Next, FIG. 9 is a flowchart showing the variable winning process (S3). When the hit flag is ON, the following processing is executed. If it is confirmed in S301 that the winning flag is ON, the display unit 11 is controlled to switch to the symbol selection screen as shown in FIG. 4 (S302). Subsequently, the left and right electric chews 20, 21 are opened in S303. In S304, when a winning of a ball to at least one of the electric chews 20, 21 is detected, the electric chew is closed and the winning flag is turned OFF (S305, S306).
[0038]
Next, it is determined whether or not the RAM 52 is read and the AT flag is ON (S307). If NO, the process jumps to S309, and if YES, the AT flag is turned OFF (S308). In S309, as described above, it is determined whether the winning symbol selected and input by the player matches the winning symbol extracted in the lottery process. If they match, display control for displaying the selection success screen is executed as shown in FIG. 4 (S310). Then, it is determined whether or not the winning symbol is an odd number (S311), and the AT flag is turned ON only when the answer is YES (S312). Then, as a preparation for executing the jackpot process, the jackpot flag is turned ON (S313).
[0039]
On the other hand, if NO is determined in S309, display control for displaying the selection failure screen is executed as shown in FIG. 4 (S314). Thereafter, the failure counter is incremented in S315. The value of the failure counter is read in subsequent step S316, and it is determined whether or not “20” has been reached. If the determination in S316 is YES, after the AT flag is turned on, the failure counter is reset and the process returns (S317, S318). That is, in this embodiment, when the winning symbol selected by the player and the winning symbol extracted in the lottery process are repeated 20 times in S309, the AT flag is turned on. Thus, the game mode is switched to the AT mode. This prevents the occurrence of a situation that is extremely detrimental to the player, such as being unable to win any jackpots.
[0040]
In this embodiment, the AT mode or the normal mode is determined depending on whether the winning symbol is odd or even. However, the symbol display unit for determining the game mode and the game mode lottery means (the CPU 50 executes the means). When a jackpot occurs, a lottery is performed to determine whether or not to enter the AT mode. When the AT mode is determined, a specific symbol is displayed on the symbol display section for determining the game mode. Thus, the game mode can be switched to the AT mode.
[0041]
Next, when the jackpot flag is turned ON, the jackpot processing (S4) shown in FIG. 10 is started. That is, when it is confirmed in S401 that the jackpot flag is ON, the attacker 22 (jackpot winning opening) is released for 20 seconds or until ten balls are won (S402). When the attacker 22 is closed, the release counter is incremented (S403). If it is confirmed in S404 that the release counter has reached 10, the jackpot flag is turned off (S405), and the release counter is reset (S406). Then, after a jackpot end process (not shown) is executed, the process returns.
[0042]
As described above, the present embodiment has been described by taking a so-called seven machine as an example. However, the present embodiment is not limited to this, and other types of pachinko gaming machines such as a third type gaming machine called a right item are not limited thereto. Of course, the present invention can be suitably employed.
