Description

  The present invention relates to a gaming machine that generates a big hit game state when a combination of symbols displayed on a symbol display device is a combination of big hit symbols on a hit line formed by arranging a predetermined number of symbols.

  2. Description of the Related Art Conventionally, in a gaming machine, for example, a pachinko gaming machine, when a combination of symbols displayed at the time of a fluctuation stop becomes a predetermined combination of a large hit symbol, a large hitting game state is established and the variable prize winning device is operated for a predetermined period of time (fixed Many proposals have been made in which the opening operation is performed a plurality of times (until the time elapses or a predetermined number of winning balls are generated) so that a large number of prize balls can be obtained in a short period of time. The symbol display device used in such a pachinko gaming machine has a plurality of symbol rows displayed on the display unit all fluctuated, and only by a combination of symbols displayed when the fluctuated symbol row is stopped. It was determined whether it was a big hit or not.

  For this reason, it is possible to determine whether or not there is a possibility of a combination of big hit symbols in a state where at least two symbol rows are stopped at the stage where the fluctuation of the plurality of symbol rows is sequentially stopped, and until the last symbol row is stopped. There was a drawback that interest did not last. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine having a symbol display device capable of maintaining interest until the last symbol row changes. .

In order to achieve the above object, in the present invention,
In a gaming machine that generates a big hit game state when a combination of symbols displayed on the symbol display device is a combination of big hit symbols in a hit line formed by arranging a predetermined number of symbols,
The symbol display device,
A variable display unit in which a plurality of symbols are sequentially stopped after the variable display under the control of the variable display control means, and one symbol is selectively displayed;
A fixed display unit fixedly displayed in a matrix so that a plurality of hit lines are established without changing a plurality of symbols same as a plurality of symbols displayed on the variable display unit,
Each time one symbol is selected and displayed on the variable display unit, the plurality of symbols on the fixed display unit are compared with a symbol for which the same symbol has not yet been selected and displayed. Display control means for displaying in an identifiable manner,
The variation display control means, display control the variation display unit so that the number of symbols selectively displayed when the start condition is satisfied is equal to or more than the predetermined number of symbols on the hit line,
When the symbol selected and displayed by the display control means is displayed on any one of the plurality of hit lines of the fixed display portion, or the combination of the symbols selectively displayed on the variable display portion is the big hit symbol. Is set to the jackpot game state when the combination of the two matches.

  Of the fixed symbols fixedly displayed on the fixed display portion, the variation of a plurality of symbols in the variation display portion is sequentially stopped, and each time one symbol is selected and displayed, the same symbol as the selected and displayed symbol is still present. A symbol that is not selected and displayed is displayed in such a manner that the player can identify it, and a big hit occurs when a combination of the symbol that is selectively displayed on the fixed display portion is displayed on any one of the plurality of hit lines. It becomes a game state. In other words, when the fluctuations are sequentially stopped on the fluctuation display section, even when the combination of symbols on the fluctuation display section at the time of the stop has no relation to the occurrence of the big hit game state, the fixed display section is selectively displayed. Since the combination of the symbols that have been displayed may be displayed on any one of the plurality of winning lines to cause a big hitting game state, the player can maintain the interest in the variable display to the end. Further, in addition to the determination of the combination of the symbols selectively displayed on the fixed display unit, the combination of the symbols selectively displayed on the variable display unit is determined, so that the combination of the symbols when the variation is stopped is the same as the conventional one. When the combination of the big hit symbol matches, the big hit game state is set, and even if the combination of the symbols at the time of stop is different and not the big hit symbol combination, the combination of the symbols selected and displayed on the fixed display portion is not changed. Since there is a case where a big hit game state is generated by being displayed on any one of the plurality of hit lines, the player can maintain the interest in the variable display to the end.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a configuration of a game board 1 of a pachinko machine as an example of a game machine to which the symbol display device 20 according to the embodiment is applied will be described with reference to FIG. FIG. 1 is a front view of the game board 1. In the figure, a game area 3 defined by a guide rail 2 provided in a substantially circular shape is formed on a front surface of a game board 1. A symbol display device 20 is disposed substantially at the center of the game area 3.

  The symbol display device 20 includes a liquid crystal display 23 that displays a variable display unit 24 that variably displays a plurality of symbols and a fixed display unit 25 that displays fixed symbols in a matrix, A plurality (four) of start-up storage LEDs 27 for notifying that the number of winning balls which have won the prize balls 6a and 6b are stored face the front, respectively. The start storage LED 27 is stored and held when a hit ball wins in the start winning prize opening 4, 6a, 6b during the fluctuation display of the fluctuation display section 24 of the liquid crystal display 23 or during the big hit game state. The start storage LED 27 is turned on by the number of times, and is turned off one by one every time the change display unit 24 starts changing. However, the number of storages is limited to a maximum of four, and starting winnings beyond that are invalidated. The symbol display device 20 will be described later in detail.

  The variable winning device 8 is arranged below the symbol display device 20 described above. The variable winning device 8 has an opening / closing plate 9 (also referred to as an attacker) that opens and closes back and forth, and the opening / closing plate 9 is opened and closed by an attacker solenoid 10. In the variable winning device 8, a winning ball number detection switch 12 for counting which detects a winning ball received with the opening / closing plate 9 opened and a V winning opening formed in the center of the opening / closing plate 9 are won. There is provided a V winning ball detection switch 11 for detecting a winning ball. The variable prize winning device 8 configured as described above has a predetermined number (for example, 10) of prizes until the opening / closing plate 9 elapses for a predetermined time (for example, 30 seconds) when a jackpot game state described later is entered. The attacker solenoid 10 is driven and opened until a ball is generated, and such an open state (this is called an open cycle) is performed a predetermined number of times (for example, 16 times; Is called the continuation number). Thus, the winning ball detection switch 12 is used to count the number of winning balls accepted during one opening of the open / close plate 9, and the V winning ball detection switch 11 is opened when the open / close plate 9 is repeatedly opened. Is used to detect the condition of

  In the game area 3, a start winning opening 4 is provided between the symbol display device 20 and the variable winning device 8. The start winning opening 4 allows the symbol display device 20 to perform a variable display. For this reason, the starting winning opening 4 has a built-in start winning ball detection switch 5 for detecting the winning of a hit ball. In addition, starting winning ports 6a and 6b having the same function as the starting winning port 4 are provided on both left and right sides of the variable winning device 8. The start winning ports 6a and 6b also have start winning ball detection switches 7a and 7b for detecting winning of a hit ball.

  Further, in the game area 3, winning holes 13a to 13d having operation lamps 14a to 14d built therein are arranged on the upper, lower, left and right sides of the symbol display device 20. These operation lamps 14a to 14d are turned on or off according to various game states. Big hit lamps 15a and 15b, which are a kind of operation lamp and blink when a big hit game state is entered, and notify the player of the fact are arranged on both left and right sides of the game area 3. Further, at the lowermost part of the game area 3, there is provided an out port 16 for collecting hit balls which do not win the above-mentioned winning port or the like. Further, the game area 3 is provided with a large number of obstacle nails and a plurality of windmills (both have no sign) that change the direction and speed of the falling ball.

  Next, the configuration of the symbol display device 20 will be described with reference to FIGS. FIG. 2 is a front view of the symbol display device 20, and FIG. 3 is a diagram illustrating symbols stopped and displayed on the liquid crystal display 23 of the symbol display device 20. As shown in FIG. 2, the symbol display device 20 has a mounting board 21 mounted on the surface of the game board 1, and a substantially rectangular display window 22 is opened on the mounting board 21. The liquid crystal display 23 faces the other side. The liquid crystal display 23 has a variable display section 24 including display columns 24a to 24d divided into four in the horizontal direction, and a fixed display in which a total of nine fixed symbols are displayed in a matrix in three rows and three columns. The display unit 25 is displayed. The numbers (designs) from "1" to "9" are independently and variably displayed in the display columns 24a to 24d of the variability display unit 24, and the variance display starts at the same time, but stops at the same time. Stopping is performed sequentially from left to right with a predetermined time difference. On the other hand, numbers (designs) from “1” to “9” are randomly drawn in the nine sections of the fixed display unit 25, and the display positions of the symbols do not change from the time of power-on. It is fixedly displayed. Each time a symbol displayed when the display columns 24a to 24d of the variable display unit 24 are stopped is determined, the same fixed symbol as the determined symbol on the fixed display unit 25 can be identified as another unfixed fixed symbol. Display as follows. In the present embodiment, the player is informed whether or not the background color of each fixed symbol is determined by lighting (changing).

  Thus, the fixed fixed symbol combination displayed on the fixed display unit 25 when the fluctuation of all the display columns 24a to 24d is stopped includes three horizontal hit lines a to c and three vertical hit lines d. If a line is placed on any one of the eight hit lines, i.e., f and two diagonal hit lines g and h, a big hit game state is established.

  In addition, when the background color on any one of the hit lines changes at the time when the three display columns 24a to 24c from the left are stopped, a reach state is set. In this reach state, as shown in FIG. 3A, the background color of the symbol of the hit line that has reached the reach is different from the background color of the other symbols. Similarly, as shown in FIG. 3B, even in the case of a big hit, the background color of the symbol of the hit line is different from the background color of the other symbols. In this case, the reach line and the big hit line may be notified by changing the form of the symbol itself or by specifically displaying the hit line.

  The mounting board 21 of the symbol display device 20 is provided with a decorative LED 26 for decoration above the mounting board 21 and a start storage LED 27 having the above-described function below the decorative LED 26. The start storage LED 27 may be displayed on the liquid crystal display 23. In addition, in the big hit game state, the number of times the opening and closing plate 9 of the variable winning device 8 is opened (also referred to as a continuation number) and the number of winnings during one opening are displayed on the liquid crystal display 23.

  The configuration of the game control circuit for controlling the operation of the symbol display device 20 and the opening and closing plate 9 of the variable winning device 8 described above will be described with reference to FIG. FIG. 4 is a block diagram showing an electric configuration of the game control circuit. The microcomputer 30 is used for the game control circuit. An external ROM 31 and an external RAM 32 are connected to the microcomputer 30. The symbol data is set in the external ROM 31.

  In the external RAM 32, a big hit miss counter 33, a big hit pattern counter 34, a reach pattern counter 35, a miss pattern counter 36, and each fixed memory 37 storing a value extracted from each of the counters 33 to 36, Is formed. Each of the determination memories 37 corresponding to the big hit loss counter 33 has a memory of the number of reserved balls of the starting winning ports 4, 6a, 6b + 1, and the value for determining the winning of each reserved ball is determined at the time of the starting winning. The determined values are stored in the corresponding determination memories 37. The big hit pattern counter 34 is a counter provided for every big hit pattern indicating which big hit symbol is arranged on which hit line. Similarly, the reach pattern counter 35 is a counter corresponding to all types of reach patterns (not shown), and the departure pattern counter 36 is a counter corresponding to all types of departure patterns (not shown). The values of the pattern counters 34 to 36 are determined at the start of the change corresponding to the winning start.

  On the other hand, start winning prize ball detection switches 5, 7a, 7b for detecting prize balls in the start winning prize openings 4, 6a, 6b, V prize ball detection switch 11 for detecting a prize ball passing through the V prize opening, and the opening and closing plate 9 The winning ball number detection switch 12 for detecting a winning ball is connected to the microcomputer 30 via a waveform shaping circuit 38. Further, the clock generation circuit 40 outputs an external interrupt signal to the INT terminal of the microcomputer 30 via the frequency divider 39. Then, the microcomputer 30 executes a main program (not shown) in synchronization with the external interrupt signal. The timing signal output from the timing signal generation circuit 41 is input to the RST1 terminal of the microcomputer 30, and a numerical value generation program (not shown) is started in synchronization with the timing signal. A reset signal output from the reset signal generation circuit 42 due to the ON operation of the power supply circuit 43 is input to the RST2 terminal of the microcomputer 30, and an initial program (not shown) is started by the reset signal.

  An LED drive circuit 44, an LCD drive circuit 45, and a driver 46 are connected to each output port of the microcomputer 30. The start drive LED 27 is connected to the LED drive circuit 44, and the liquid crystal display 23 (display as LCD) is connected to the LCD drive circuit 45. The driver 46 drives and controls the attacker solenoid 10 and the operation lamps 14a to 14d, 15a, and 15b in accordance with a signal from the microcomputer 30. Note that a microcomputer dedicated to the LCD may be provided between the microcomputer 30 and the LCD drive circuit 45, and the LCD 23 may be controlled by the microcomputer.

  Next, among the operations controlled by the above-described game control circuit, the operation in the start winning prize will be described with reference to FIG. 5. In step 10, a hit ball wins one of the start winning prize openings 4, 6a, 6b. It is determined whether or not the corresponding start winning prize ball detection switches 5, 7a, 7b are turned on to derive a start winning prize signal. If there is no start prize signal, the subroutine is terminated. For example, in step 20, it is determined whether or not the value of the start winning counter C is smaller than 4. When the value of the start winning counter C is greater than 4, the subroutine is terminated without performing the following processing because the four starting winnings are already stored, and the value of the starting winning counter C is smaller than 4. At this time, the value of the start winning counter C is updated in step 30 and then the current value of the big hit loss counter 33 is stored in the corresponding determination memory M (c) in step 40. It should be noted that, for example, the big hit loss counter 33 changes the value from 0 to 234 every moment, and when the value extracted at the time of the start winning is, for example, “0”, it is determined that the hit is a hit and “1 to 20”. Is determined to be a reach (but eventually deviates), and when the value is any other value, it is determined to be deviated. When a predetermined condition in the game (for example, a condition that the odd-numbered jackpot gaming state is ended) is satisfied, if the appearance probability of the jackpot is set to be a high probability, the big hit loss counter 33 is set. May be changed so as to reduce the upper limit value of.

  Next, the variable display operation of the liquid crystal display 23 will be described with reference to FIGS. FIGS. 6 and 7 are flowcharts showing the variable display operation of the liquid crystal display 23. First, in the big hit gaming state, the liquid crystal display 23 displays a symbol that has become a normal big hit, the number of continuations, and the number of winnings. If it is determined in step 100 that the big hit flag is set, the following will be performed. Is not executed.

  On the other hand, if it is determined that the big hit flag is not set, the display state of the liquid crystal display 23 is determined in steps 110 to 140. Specifically, at step 110, it is determined whether or not all the display columns 24a to 24d of the variable display unit 24 are in a changing state (state flag F = 1). At step 120, only the left display column 24a is changed. Is determined to be in a state in which it has stopped changing (state flag F = 2), and it is determined in step 130 whether or not the middle left display column 24b is in a state in which it has stopped changing (state flag F = 3). In step 140, it is determined whether or not the middle right display column 24c is in a state where the change is stopped (state flag F = 4). In step 150, the combination of symbols displayed on any one of the hit lines is in the reach state (state It is determined whether or not the flag F = 5).

  When none of the above-mentioned states is present (when the state is not fluctuating), the state flag F = 0, and at this time, the start winning counter which stores the winning of the hit ball into the start winning holes 4, 6a, 6b in step 160. It is determined whether or not the value of C is 1 or more. If there is no stored value in the start winning counter C, the process ends without executing the following processing of the variable display subroutine.

  When the value of the start winning counter C is 1 or more, the timers t1, t2, t3, and t4 are set in step 170, and the change of all the display columns 24a to 24d is started in step 180, and the value of the state flag F is changed to " "1" is set, and the value of the starting winning counter C is decremented by one. Next, in step 190, the value of the big hit loss decision memory M (c) is updated to a lower memory, and it is determined in step 200 whether or not the value of M (0) in the updated decision memory is a big hit. You. When it is determined that the value of M (0) is a big hit, in step 210, one value is extracted from the current big hit pattern counter 34 and stored in the corresponding decision memory, while it is determined that it is not a big hit. In step 220, it is determined whether or not the value of M (0) is reach. If it is reach, one value is extracted from the reach pattern counter 35 in step 230 and stored in the corresponding decision memory. , If not, one value is extracted from the off pattern counter 36 in step 240 and stored in the corresponding decision memory.

By the way, the timers t1, t2, t3, and t4 regulate the fluctuation time of the left display column 24a, the middle left display column 24b, the middle right display column 24c, and the right display column 24d.
t1 <t2 <t3 <t4; t2-t1 ≒ t3-t2 ≒ t4-t3
In a relationship. Then, it is determined in step 250 that the timer t1 has expired. If the timer has not expired, step 250 → end of the variable display subroutine → start of the variable display subroutine to step 110 → step 250 →... repeat.

  When it is determined that the timer t1 has expired, the variable display of the left display column 24a is stopped in step 260 along the selected pattern, and the value of the state flag F is set to "2". In step 270, the background color of the symbol corresponding to the fixed display unit 25 is changed. Similarly, in step 280, it is determined whether or not the time of the timer t2 has expired. If it is determined that the time has expired, the variable display of the middle left display column 24b is stopped in step 290 along the selected pattern. At the same time, the value of the state flag F is set to "3", the background color of the corresponding symbol on the fixed display unit 25 is changed in step 300, and it is determined in step 310 whether the timer t3 has timed out. If it is determined that the time is up, the variable display in the middle right display column 24c is stopped along the selected pattern in step 320, and the value of the state flag F is set to "4" in step 320. The background color of the corresponding symbol on the fixed display unit 25 is changed. Then, when the variable display of the display columns 24a to 24c excluding the right end is stopped, it is determined in step 340 whether the value of M (0) is a big hit or a reach, that is, whether or not the reach display is performed. .

  If the reach display is not performed, it is determined in step 350 whether or not the timer t4 has timed out. Until the timer t4 has timed out, step 350 → variation display subroutine end → variation display subroutine start-step 140 → step 350 →. .. are repeated, and when the time is up, go to step 390.

  On the other hand, if it is determined that the reach display is made, it is determined in step 360 whether or not the value of the status flag F is "5". If not, the timer t5 is newly set in step 370. At the same time, the value of the status flag F is set to "5". Here, the timer t5 extends the fluctuation time of the right display column 24d, which last stops fluctuation in the reach state. Then, it is determined in step 380 whether or not the timer t5 has timed out. Step 380 → the end of the variable display subroutine → the start of the variable display subroutine—step 150 → step 380 →... When the timer t5 has expired, the routine proceeds to step 390.

  When the timer t4 when the reach display is not performed is timed up, and when the timer t5 when the reach display is performed is timed up, the variable display of the right display column 24d is stopped in step 390 along the selected pattern, and step 400 is performed. To change the background color of the corresponding symbol on the fixed display unit 25. Thereafter, at step 410, it is determined whether or not the lighting symbol (background color changing symbol) of the fixed display unit 25 is on any of the hit lines a to h. To reset the status flag, and if it is determined that the line is on the hit line, the status flag is reset and the big hit flag is set in step 430, and then the variable display subroutine ends. When the big hit flag is set in step 430, the open mode until the opening / closing plate 9 of the variable winning device 8 elapses a predetermined time or a predetermined number of winning balls is generated according to a subroutine (not shown) is performed a predetermined number of times. Execute. When the opening mode of the opening / closing plate 9 is completed a predetermined number of times, the big hit flag is reset.

  As described above, the configuration and operation of the pachinko gaming machine provided with the symbol display device 20 according to the embodiment have been described. According to the present embodiment, of the fixed symbols displayed on the fixed display unit 25, Each time the variation of the display columns 24a to 24d is sequentially stopped and determined, the background color is changed so that the corresponding symbol can be distinguished from the other unfixed fixed symbols, and the fixed symbol combination of the fixed display unit 25 is changed. A big hitting game state is established when they are arranged on a predetermined hitting line. In other words, when the fluctuations are sequentially stopped in the display columns 24a to 24d of the fluctuation display unit 24, even if the combination of the symbols on the fluctuation display unit 24 at the time of the stop has no relation to the occurrence of the big hit gaming state. Since the combination of the fixed symbols in the fixed display unit 25 may be arranged on any one of the hit lines a to h to generate the big hit game state, the player may maintain his or her interest in the variable display to the end. it can.

  In the above-described embodiment (first embodiment), it is determined whether or not a big hit occurs only on the hit line of the fixed display unit 25. The combination of symbols in the unit 24 may be determined to be a big hit. For example, as shown in the embodiment of FIG. 8 (second embodiment), when the fixed symbols of the first and second stopped display columns 24a and 24b of the variable display unit 24 having three display columns 24a to 24c are the same. In this case, since there is no possibility that a big hit is established in all the hit lines a to e in the fixed display unit 25 having five hit lines, the hit line f is also set in the variable display unit 24 in this case. When the same number is aligned on the hit line f, the big hit game state is set. By doing so, there is an expectation that a winning line will be established on the fixed display unit 25 even if the symbols sequentially determined on the variable display unit 24 are different, and the symbols sequentially determined on the variable display unit 24 will be described. Is likely to be a combination of big hit symbols as in the past, there is a sense of expectation that a big hit will occur even if the symbols whose background color is changed on the fixed display unit 25 are not aligned on the hit line. In any case, the player can keep his interest in the variable display until the end.

  In the above-described embodiment, one symbol is displayed in each display column of the variable display unit 24, but a plurality of symbols may be displayed as in the fixed display unit 25. Further, one display column may be changed a plurality of times, and the background color of the corresponding symbol on the fixed display unit may be changed every time the change is stopped. Further, although the description has been given on the assumption that the arrangement of the fixed symbols displayed on the fixed display unit 25 does not change, the arrangement of the fixed symbols may be determined immediately before the change of the variable display unit 24 is started. The arrangement of the fixed symbols on the fixed display unit 25 may be changed every time a predetermined time elapses, each time a predetermined number of changes are completed, each time the player desires, or the like. Conversely, a display in which the design of the fixed display portion 25 is completely fixed (for example, a display or a display object with a design drawn on a sticker) may be used. In the above-described embodiment, the variable display unit 24 and the fixed display unit 25 are displayed on one liquid crystal display 23. However, different displays (segment LED, LCD, CRT, dot matrix LED, etc.) are used. May be displayed separately. Also, the symbols determined by the variable display unit 24 are not displayed on the fixed display unit 25, that is, the number of symbol types that can be displayed on the variable display unit 24 and the number of symbol types displayed on the fixed display unit 25. The fluctuation display unit 24 may be fluctuation-controlled in a state in which the and are mismatched. The hit line is not limited to a straight hit line, but may be a broken-line hit line or an oblique parallel hit line. In addition, the game content of the pachinko machine may be not only a so-called digital game but also a hikoki-type game or a right-generating game. Furthermore, the present invention may be applied to slot machines, TV games, and the like as well as pachinko machines as game machines, including the above-mentioned modified examples.
