Description

  The present invention relates to a gaming machine such as a pachinko gaming machine or a coin gaming machine, and particularly includes a variable display device whose display state can be changed, and a display result in the variable display device becomes a predetermined specific display mode. The present invention relates to a gaming machine that can be given a predetermined gaming value.

  As a gaming machine, a variable display device having a variable display unit whose display state can be changed is provided, and a big hit game that is advantageous to the player when the display result of the variable display unit becomes a predetermined specific display mode Some are configured to transition to a state. The variable display device has a plurality of variable display units, and is usually configured to display the display results of the plurality of variable display units at different times. For example, a plurality of pieces of identification information (special symbols) such as symbols are variably displayed on the variable display portion. That the display result of the variable display unit is a combination of specific display modes determined in advance is usually referred to as “big hit”. Note that the game value is the right that the state of the variable winning ball device provided in the gaming area of the gaming machine is advantageous for a player who is likely to win a ball, or the advantageous state for a player. It is to generate.

  When the big hit occurs, for example, the big winning opening is opened a predetermined number of times, and the game shifts to a big hit gaming state where the hit ball is easy to win. And in each open period, if there is a prize for a predetermined number (for example, 10) of the big prize opening, the big prize opening is closed. And the number of times the special winning opening is opened is fixed to a predetermined number (for example, 16 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and even if the number of winnings does not reach a predetermined number, the big winning opening is closed when the opening time elapses. In addition, when a predetermined condition (for example, winning in a V zone provided in the big prize opening) is not established at the time when the big prize opening is closed, the big hit game even if the predetermined number of times is not reached The state ends.

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

  As a gaming machine, there is also known a game machine having a decorative symbol display unit that variably displays a decorative symbol or the like in addition to a variable display unit that variably displays a simple special symbol. In such a gaming machine, the total number of special symbols is less than the total number of decorative symbols. Therefore, the control load regarding the variable display of the special symbol is reduced. In order to prevent a reduction in the game effect due to the small number of special symbols, the display effect by the decorative symbols is made rich in variations.

  The game progress in the gaming machine is controlled by game control means such as a microcomputer. The image information displayed on the variable display device is controlled by display control means that operates in accordance with display control command data from the game control means. Image information displayed on the variable display device is generally controlled by a display control microcomputer and a video display processor (VDP) that generates image data and transfers it to the variable display device according to instructions from the microcomputer. However, the program capacity of the display control microcomputer is large. Therefore, it is impossible to control identification information and the like displayed on the variable display device by the microcomputer of the game control means having a limited program capacity, and the display control microcomputer (separate from the microcomputer of the game control means) Display control means) is used.

  Accordingly, the game control means for controlling the progress of the game needs to transmit a display control command to the display control means. Image data such as symbols is generated by the display control means, but from the viewpoint that the game control means for controlling the progress of the game should be used for the display position of the changing symbols on the screen every moment. Determined by game control means. Therefore, the game control means determines the display position of the symbol at every appropriate timing, and transmits the display position to the display control means.

However, when the game control unit is configured to determine the display position of the changing symbol, the control load related to the symbol display of the game control unit is heavy, and the game control unit spends other game control. There is a problem that processing time that can be limited. In order to solve such a problem, for example, the game control means transmits to the display control means a time point (including change start and stop) of the symbol speed change, and the symbol display is displayed according to the speed received by the display control means. It is conceivable to determine the position. However, even with such symbol variation control, a command is transmitted from the game control unit to the display control unit many times during one variation, so that the control burden on the symbol display of the game control unit is still large. This is true not only when the display control means performs display control of special symbols, but also when the display control means is configured to display control the above-described decorative symbols. . In addition, when a big hit occurs, it becomes a very advantageous state for the player, so there is a possibility that a fraudulent act that illegally generates a big hit is performed. There is a possibility that fraudulent acts may be made not only from the front side of the gaming machine but also by tampering with various circuit boards installed on the back side of the gaming machine.

Therefore, the present invention is a gaming machine having a symbol display unit for variably displaying special symbols and decorative symbols, and abundant display effects are output from the game control means to the display control means even if the display effects are abundant. It is an object of the present invention to provide a gaming machine that does not increase the number of commands that are executed, and that can effectively prevent fraud and make it difficult to receive fraud.

Gaming machine according to the present invention, together with a controllable beneficial gaming state to the player when the special symbol display section displays the result of the special symbols that are variably displayed becomes a specific display mode predetermined, organic interest A gaming machine that can be controlled in a special gaming state in which the display result of the special symbol is likely to be in a specific display mode as compared to when the normal state is over after completing the gaming state, and a game control means for controlling the progress of the game, includes a variable display device having a decorative symbol display unit for displaying a decorative pattern at least special symbol display unit, and a variable display control means for controlling a display state of the variable display device, the variable display control means, special symbol display section capable of displaying special symbols and special symbol display control means for controlling the variable display, decorative symbol display unit more kinds of display contents than the display contents can be displayed on the special symbol display unit furnished And a pattern display control means, predetermination of the game control means, is determined before advantageous gaming state to whether a special game state and whether preparative display results in a special symbol display unit for are derived displayed Variable display control via an irreversible output means that can transmit information about a special symbol variable display start that can specify a variable display period based on the establishment of a variable display start condition. and outputs to the means, and outputting a specific possible commands and determination of whether the result is a determination of whether or not results and special game state to an advantageous gaming state by predetermination means on the variable display control means, the variable A game control in which a command indicating confirmation is output to the variable display control means when the display period ends, and the variable display control means is input via an irreversible input means capable of transmitting information only in one direction. Between the variable display period specified on the basis of a command to a variable display start from stage to variably display the decorative pattern by using a decorative symbol display control means causes the variable display of the special symbol by using a special symbol display control means, A determination result specified by a command that can specify a determination result of whether or not to make an advantageous gaming state by a pre-determining means and a determination result of whether or not to make a special gaming state, and a display result of a special symbol display unit, Variable display control is performed so that the display result of the decorative symbol display unit is consistent, and at the timing when the command indicating the confirmation from the game control means is output, the special symbol is stopped and displayed on the special symbol display unit and the decorative symbol display unit The decorative design is stopped and displayed.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the overall configuration of a pachinko gaming machine that is an example of a gaming machine will be described. 1 is a front view of the pachinko gaming machine 1 as seen from the front, FIG. 2 is an overall rear view showing the internal structure of the pachinko gaming machine 1, and FIG. 3 is a rear view of the gaming board of the pachinko gaming machine 1 as seen from the back. Here, a pachinko gaming machine is shown as an example of a gaming machine, but the present invention is not limited to a pachinko gaming machine, and may be, for example, a coin gaming machine.

  As shown in FIG. 1, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape. On the lower surface of the glass door frame 2 is a hitting ball supply tray 3. Below the hitting ball supply tray 3, there are provided an extra ball receiving tray 4 for storing prize balls overflowing from the hitting ball supply tray 3 and a hitting operation handle (operation knob) 5 for firing the hitting ball. A game board 6 is detachably attached to the rear side of the glass door frame 2. A game area 7 is provided in front of the game board 6.

  Near the center of the game area 7, there is provided a variable display device 8 including a variable display unit 9 for variably displaying a plurality of types of symbols and a variable display 10 using 7 segment LEDs. In this embodiment, the variable display unit 9 includes a special symbol display area for variably displaying special symbols and a decorative symbol display area for variably displaying decorative symbols.

  A passing gate 11 for guiding a hit ball is provided on the side of the variable display device 8. The hit ball that has passed through the passing gate 11 is guided to the start winning opening 14 through the ball outlet 13. In the passage between the passage gate 11 and the ball exit 13, there is a gate switch 12 that detects a hit ball that has passed through the passage gate 11. The winning ball that has entered the start winning opening 14 is guided to the back of the game board 6 and detected by the start opening switch 17. A variable winning ball device 15 that opens and closes is provided below the start winning opening 14. The variable winning ball device 15 is opened by a solenoid 16.

  An open / close plate 20 that is opened by a solenoid 21 in a specific gaming state (big hit state) is provided below the variable winning ball device 15. In this embodiment, the opening / closing plate 20 is a means for opening and closing the special winning opening. Of the winning balls guided from the opening / closing plate 20 to the back of the game board 6, the winning ball entering one (V zone) is detected by the V count switch 22. A winning ball from the opening / closing plate 20 is detected by the count switch 23.

  At the bottom of the variable display device 8, a start winning memory display 18 having four display units for displaying the number of winning balls that have entered the start winning opening 14 is provided. In this example, with the upper limit being four, each time there is a start prize, the start prize storage display 18 increases the number of lit display units one by one. Each time the variable display of the special symbol on the variable display unit 9 is started, the number of the lit display units is reduced by one.

  The game board 6 is provided with a plurality of winning openings 19, 24. Decorative lamps 25 blinking during the game are provided around the left and right sides of the game area 7, and an outlet 26 for absorbing a hit ball that has not won a prize is provided below. Two speakers 27 that emit sound effects are provided on the left and right upper portions outside the game area 7. On the outer periphery of the game area 7, a game effect LED 28a and game effect lamps 28b and 28c are provided. In this example, a prize ball lamp 51 that is lit when a prize is paid out is provided in the vicinity of one speaker 27, and a ball break lamp 52 that is lit when a supply ball is cut is provided in the vicinity of the other speaker 27. Is provided. Further, FIG. 1 also shows a card unit 50 that is installed adjacent to the pachinko gaming machine 1 and enables ball lending by inserting a prepaid card.

  The hit ball fired from the hit ball launching device enters the game area 7 through the hit ball rail, and then descends the game area 7. When the hit ball is detected by the gate switch 12 through the passing gate 11, the display number (ordinary symbol) of the variable display 10 is continuously changed.

  Further, when the hit ball enters the start winning opening 14 and is detected by the start opening switch 17, the special symbol in the variable display portion 9 starts to rotate if the variation of the symbol can be started. If the special symbol variation cannot be started, the start winning memory is increased by one. The start winning memory will be described in detail later. The variable display of the special symbol in the variable display unit 9 stops when a certain time has elapsed.

  If the display state of the special symbol at the time of the stop is the display state of the jackpot symbol, the game shifts to the jackpot game state. That is, the opening / closing plate 20 is opened until a predetermined time elapses or a predetermined number (for example, 10) of hit balls wins. When the hit ball enters the specific winning area while the opening / closing plate 20 is opened and is detected by the V count switch 22, a right to continue is generated and the opening / closing plate 20 is opened again. The generation of the continuation right is allowed a predetermined number of times (for example, 15 rounds).

  Further, when the stop symbol on the variable display 10 is a predetermined symbol (winning symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the high probability state, the probability that the stop symbol in the variable display 10 becomes a winning symbol is increased, and the opening time and the number of times of opening of the variable winning ball device 15 are increased.

Next, the structure of the back surface of the pachinko gaming machine 1 will be described with reference to FIG.
On the back surface of the variable display device 8, as shown in FIG. 2, a prize ball tank 38 is provided above the mechanism plate 36, and the prize ball is placed from above in a state where the pachinko gaming machine 1 is installed on the gaming machine installation island. It is supplied to the prize ball tank 38. The prize balls in the prize ball tank 38 pass through the guide rod 39 and reach the ball dispensing device.

  The mechanism plate 36 includes a variable display control unit 29 for controlling the variable display unit 9 via the relay board 30, a game control board (main board) 31 covered with a board case 32 and mounted with a game control microcomputer, etc. A relay board 33 for relaying a signal between the variable display control unit 29 and the game control board 31, and a prize ball board 37 on which a payout control microcomputer for performing payout control of prizes is mounted. Yes. Further, on the mechanism plate 36, a ball hitting device 34 that launches a hit ball to the game area 7 by using the rotational force of the motor, and a lamp control for sending signals to the speaker 27 and the game effect lamps / LEDs 28a, 28b, 28c. A substrate 35 is installed.

  FIG. 3 is a rear view of the game board of the pachinko gaming machine 1 as seen from the back. On the back surface of the game board 6, as shown in FIG. 3, a winning ball collective cover 40 is provided for guiding the winning balls that have won the winning holes and the winning ball devices along a predetermined winning path. Among the winning balls led to the winning ball collective cover 40, those that win through the opening / closing plate 20 are controlled so that the ball paying device 97 pays out a relatively large number of prize balls (for example, 15). What is won through the start winning opening 14 is controlled such that a ball payout device (not shown in FIG. 3) pays out a relatively small number of prize balls (for example, 6). And what was won through the other winning opening 24 and the winning ball device is controlled such that the ball payout device pays out a relatively medium number of prize balls (for example, 10). In FIG. 3, the relay board 33 is illustrated.

  In order to perform the winning ball payout control, signals from the winning ball detection switch 99, the start port switch 17 and the V count switch 22 are sent to the main board 31. When the ON signal of the winning ball detection switch 99 is sent to the main board 31, a winning ball number signal is sent from the main board 31 to the winning ball board 37. The winning ball detection switch 99 detects that there has been a winning. In this case, a prize ball number signal is given from the main board 31 to the winning ball board 37. For example, when the winning ball detection switch 99 is turned on in response to the start port switch 17 being turned on, “6” is output to the winning ball number signal, and in response to the turning on of the count switch 23 or the V count switch 22, winning ball detection is performed. When the switch 99 is turned on, “15” is output as the prize ball number signal. Then, if the winning ball detection switch 99 is turned on when those switches are not turned on, “10” is output as the winning ball number signal.

  FIG. 4 is a block diagram illustrating an example of a circuit configuration in the main board 31. 4 also shows a prize ball board 37, a lamp control board 35, a sound control board 70, a launch control board 91, and a display control board 80. On the main board 31, a basic circuit 53 that controls the pachinko gaming machine 1 according to a program, and signals from the gate switch 12, the start port switch 17, the V count switch 22, the count switch 23, and the winning ball detection switch 99 are input to the basic circuit 53. Switch circuit 58 applied to the motor, solenoid 16 for opening / closing the variable winning ball apparatus 15 and solenoid circuit 59 for driving the solenoid 21 for opening / closing the opening / closing plate 20 in accordance with a command from the basic circuit 53, and turning on / off of the start memory display 18 A lamp / LED circuit 60 for driving the variable display 10 by the 7-segment LED and the decorative lamp 25 is included.

  Further, according to the data given from the basic circuit 53, the jackpot information indicating the occurrence of the jackpot, the effective starting information indicating the number of starting winning balls used for starting the special symbol variation display of the variable display unit 9, and the probability variation has occurred. And an information output circuit 64 for outputting to the host computer such as a hall management computer.

  The basic circuit 53 includes a ROM 54 that stores a game control program and the like, a RAM 55 that is used as a work memory, a CPU 56 that performs a control operation according to a control program, and an I / O port unit 57. Note that the ROM 54 and RAM 55 may be built in the CPU 56.

Further, an initial reset circuit 65 for resetting the basic circuit 53 when the power is turned on is provided on the main board 31, and a reset pulse is given to the basic circuit 53 periodically (for example, every 2 ms) to start a game control program. A reset circuit 66 for re-execution from the start address, and an address for outputting a signal for selecting any I / O port of the I / O port unit 57 by decoding the address signal given from the basic circuit 53 A decoding circuit 67 is provided.
Note that there is also switch information input to the main board 31 from the ball dispensing device 97, but these are omitted in FIG.

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

  FIG. 5 is a block diagram showing a circuit configuration in the display control board 80 together with a CRT 82 which is an example of realization of the variable display unit 9 and the output buffer circuit 63 of the main board 31. The display control CPU 101 operates in accordance with a program stored in the control data ROM 102. When a strobe signal is input from the main board 31 via the noise filter 107 and the input buffer circuit 105, the display control CPU 101 performs display control via the input buffer circuit 105. Receive commands.

  Then, the display control CPU 101 performs display control of the screen displayed on the CRT 82 in accordance with the received display control command. Specifically, a command corresponding to the display control command is given to the VDP 103. The VDP 103 reads out necessary data from the character ROM 86. The VDP 103 generates image data to be displayed on the CRT 82 according to the input data, and stores the image data in the VRAM 87. The image data in the VRAM 87 is converted into R, G, and B signals, converted into analog signals by the DA conversion circuit 104, and output to the CRT 82.

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

  The input buffer circuit 105 in the display control board 80 can pass signals only in the direction from the main board 31 to the display control board 80. Therefore, there is no room for signals to be transmitted from the display control board 80 side to the main board 31 side. Even if the tampering is added to the circuit in the display control board 80, the signal output by the tampering is not transmitted to the main board 31 side. For example, a three-terminal capacitor or a ferrite bead is used as the noise filter 107 that cuts off the high-frequency signal. However, even if noise is added between the substrates due to the presence of the noise filter 107, the influence is eliminated. .

  Further, in the main board 31, the output of the output ports 571 and 572 for sending the display control command may be output to the display control board 80 as it is, but an output buffer circuit 63 capable of transmitting a signal only in one direction is provided. As a result, the signal output section has a two-stage configuration, and one-way signal transmission from the main board 31 to the display control board 80 can be made more reliable.

Next, the operation of the gaming machine will be described.
FIG. 6 is a flowchart showing the operation of the basic circuit 53 on the main board 31. As described above, this processing is started, for example, every 2 ms by a reset pulse generated by the periodic reset circuit 66. When the basic circuit 53 is activated, the basic circuit 53 first sets the clock monitor register built in the CPU 56 to the clock monitor enable state in order to enable the clock monitor control (step S1). Note that the clock monitor control is a control that automatically generates a reset within the CPU 56 when a drop or stop of the input clock signal is detected.

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

  Next, after performing processing for setting command data sent to the display control board 80 in a predetermined area of the RAM 55 (display control data setting processing: step S4), processing for outputting the command data as display control command data is performed. Performed (display control data output processing: step S5).

  Next, a process of outputting the contents of the storage area for various output data to each output port is performed (data output process: step S6). Also, the process of decrementing the lamp timer by 1 is performed, and when the lamp timer times out (= 0), the lamp data pointer is updated and a new value is set in the lamp timer (lamp timer process: step S7).

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

Next, a process of updating each counter indicating each determination random number such as a big hit determination random number used for game control is performed (step S10).
FIG. 7 is an explanatory diagram showing each random number. Each random number is used as follows.
(1) Random 1: Decide whether or not to generate a big hit (for big hit judgment)
(2) Random 4: Decide whether or not to reach when falling off (for reach determination)
(3) Random 6: Reach type is determined (for reach type determination)
(4) Random 7: For probability variation determination (high probability state: for determining whether or not to increase the probability of generating a big hit)

In order to enhance the game effect, random numbers other than the random numbers (1) to (4) are also used.
In step S10, the CPU 56 counts up (adds 1) a counter for generating the jackpot determination random number (1) and the probability variation determination random number (4). That is, they are determination random numbers.

  Next, the CPU 56 performs special symbol process processing (step S11). In the special symbol process control, corresponding processing is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state. Also, normal symbol process processing is performed (step S12). In the normal symbol process, the corresponding process is selected and executed in accordance with the normal symbol process flag for controlling the variable display 10 using the 7-segment LED in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Further, the CPU 56 inputs the state of each switch via the switch circuit 58 and performs necessary processing according to the switch state (switch processing: step S13). Further, a process of sending audio data in process data, which will be described later, to the audio control board 70 is performed (audio processing: step S14).

  The basic circuit 53 further performs a process of updating the display random number (step S15). That is, the counter for generating random numbers 4 and 6 is incremented (added by 1).

The basic circuit 53 performs signal processing with the prize ball substrate 37 (step S16). That is, when a predetermined condition is satisfied, a prize ball control command indicating the number of prize balls is output to the prize ball substrate 37. The prize ball control CPU mounted on the prize ball substrate 37 drives the ball dispensing device 97 according to the received number of prize balls.
After that, the basic circuit 53 repeats the display random number update process in step S17 until the next reset pulse is given from the periodic reset circuit 66.

  Next, the symbol variation start process variably displayed on the variable display portion 9 based on the winning at the start winning opening 14 will be described with reference to the flowcharts of FIGS. FIG. 8 shows a process for determining that the hit ball has won the start winning opening 14, and FIG. 9 shows a process for determining the symbol variation method. FIG. 10 is a flowchart showing a process for determining whether or not to win.

  When the hit ball wins the start winning opening 14 provided in the game board 6, the start opening sensor 17 is turned on. In the special symbol process in step S8 of the main process, as shown in FIG. 8, when the CPU 56 determines that the start port sensor 17 is turned on via the switch circuit 58 (step S41), the start winning memorized number is maximum. It is confirmed whether or not the value 4 is reached (step S42). If the starting winning memory number has not reached 4, the starting winning memory number is increased by 1 (step S43), and the value of the jackpot determining random number is extracted. Then, it is stored in a random value storage area corresponding to the value of the number of stored start winning prizes (step S44). When the start winning memory number has reached 4, the process for increasing the starting win memory number is not performed. That is, in this embodiment, it is possible to store the number of hit balls that have been won in a maximum of four start winning holes 17.

  As shown in FIG. 9, the CPU 56 confirms the value of the number of start winning prizes in the special symbol process processing in step S8 (step S50). If the starting winning memory number is not 0, the value stored in the random number value storage area corresponding to the starting winning memory number = 1 is read (step S51), the value of the starting winning memory number is decreased by 1, and each The value in the random value storage area is shifted (step S52). That is, the value stored in the random number value storage area corresponding to the starting winning memory number = n (n = 2, 3, 4) is stored in the random number value storing area corresponding to the starting winning memory number = n−1. .

  Then, the CPU 56 determines the winning / losing based on the value read in step S51, that is, the value of the extracted big hit determination random number (step S53). Here, the jackpot determination random number takes a value in the range of 0-299. As shown in FIG. 10, at the time of low probability, for example, when the value is “3”, it is determined as “big hit”, and when it is any other value, it is determined as “out of place”. When the probability is high, for example, when the value is any one of “3”, “7”, “79”, “103”, “107”, “big hit” is determined. It is determined that it is out of place.

  When it is determined that it is a big hit, a random number for probability variation determination (random 7) is extracted, and if the value is an odd number, it is determined to be in a high probability state (step S68). Further, a reach type determination random number (random 6) is extracted, and the reach type is determined based on the value (step S57).

  If it is determined that there is a loss, the CPU 56 determines whether or not to reach (step S58). For example, when the value of random 4, which is a random number for reach determination, is any one of “105” to “1530”, it is determined not to reach. If the value of the reach determination random number is any one of “0” to “104”, it is determined to reach. When determining to reach, the CPU 56 determines the reach type (step S57).

  If it is decided not to reach in step S58, if it is a high probability state, it is decided whether the variation period of the special symbol is a normal period or a shortened period (step S67). The determination is performed using, for example, a random number.

  In the high probability state, the probability of the next big hit increases, the time until the variable display of the variable display 10 is confirmed by the 7-segment LED is shortened, and based on the variable display result of the variable display 10. The pachinko gaming machine 1 may be configured to increase the number of times and the opening time of the variable winning ball apparatus 15 at the time of winning, and the probability of winning based on the variable display result of the variable display 10 is increased. It may be configured. In addition, the present invention is also applicable to the pachinko gaming machine 1 in which only one or a plurality of the states occur.

  Further, the random number and the range of the random value used in this embodiment are merely examples, and any random number may be used, and the range setting is also arbitrary.

  FIG. 11 is a flowchart showing an example of a special symbol process processing program executed by the CPU 56. The special symbol process shown in FIG. 11 is a specific process of step S11 in the flowchart of FIG. When performing the special symbol process, the CPU 56 performs any one of steps S300 to S309 shown in FIG. 11 according to the internal state. In each process, the following process is executed.

  Special symbol variation waiting process (step S300): Waiting for the start opening sensor 17 to be turned on after hitting the start winning opening 14 (the winning opening of the variable winning ball apparatus 15 in this embodiment). When the start sensor 17 is turned on, if the start winning memory number is not full, the start winning memory number is incremented by 1 and a big hit determining random number is extracted. That is, the process shown in FIG. 8 is executed.

  Special symbol determination process (step S301): When variable symbol special display can be started, the number of start winning memories is confirmed. If the start winning memorization number is not 0, it is determined whether to win or not depending on the value of the extracted jackpot determination random number. That is, the first half of the process shown in FIG. 9 is executed.

  Reach operation setting process (step S303): It is determined whether or not a reach operation is performed according to the value of the reach determination random number, and a reach variable display pattern is determined according to the value of the reach type determination random number. That is, the second half of the process shown in FIG. 9 is executed.

  All symbol variation start processing (step S304): Control is performed so that the variable display unit 9 starts variation of all the special symbols and decorative symbols. At this time, a variable display pattern and information for instructing whether or not to make a big hit are transmitted to the display control board 80.

  All symbols stop waiting process (step S305): When a predetermined time has elapsed, control is performed so that the special symbols and decorative symbols displayed on the variable display unit 9 are stopped.

  Jackpot display process (step S306): When it is determined to be a jackpot, the internal state (process flag) is updated to shift to step S307. If not, the internal state is updated to shift to step S309.

  Big winning opening opening process (step S307): Control for opening the big winning opening is started. Specifically, the counter and the flag are initialized, and the solenoid 21 is driven to open the special winning opening.

  Processing for opening a special prize opening (step S308): Control for sending display control command data for the big prize opening round display to the display control board 80, processing for confirming establishment of a closing condition for the special prize opening, and the like. If the closing condition for the big prize opening is satisfied, the internal state is updated to shift to step S307 if the end condition for the big hit gaming state is not satisfied. If the end condition for the big hit gaming state is satisfied, the internal state is updated to shift to step S309.

  Jackpot end process (step S309): A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flag and the like are returned to the initial state, and the internal state is updated to shift to step S300.

  As described above, when a hit ball is won at the start winning opening 14, the basic circuit 53 determines whether to win or not in the special symbol process in step S11 (see FIG. 6), and determines a variable display pattern. However, the display control command corresponding to the determination is given to the display control CPU 101 of the display control board 80. The display control CPU 101 performs display control of the variable display unit 9 in accordance with a display control command from the main board 31.

Next, the variation of symbols will be described using a specific example.
FIG. 12 is an explanatory diagram showing a special symbol used in this embodiment. In this embodiment, it is assumed that there are two types of special symbols. One is a winning symbol and the other is a missed symbol. During the change, the special symbol display area of the variable display unit 9 is alternately switched and displayed with a symbol that is different from the winning symbol. The switching speed is always the same. When a winning symbol is displayed at the end of the change (switching display), a big hit is made and a big hit gaming state is started. In addition, when the variation is finished, the shifted symbol is not displayed. That is, when a big hit occurs, the winning symbol becomes a stop symbol, and when the big hit occurs, the lost symbol becomes a stop symbol.

  FIG. 13 is an explanatory diagram showing an example of a decorative pattern on the left and right sides used in this embodiment. In this embodiment, the decorative symbol display area of the variable display section 9 has three display areas on the left and right. And as shown in FIG. 13, each symbol displayed as a decorative symbol in the left and right is the same 12 symbols in the left and right. When the symbol number 12 is displayed, the symbol number 1 is displayed next. When the stop symbol of the special symbol is a winning symbol, that is, when a big hit occurs, the left and right middle symbols stop at the same symbol.

  FIG. 14 is an explanatory diagram showing a display example of the variable display unit 9 during symbol variation. (A) shows a state in which the special symbol is changing in the special symbol display area 9A, the decorative symbol is changing in the decorative symbol display area 9B, and a shifted symbol appears in the special symbol display area 9A. . (B) shows a state where a big hit symbol appears in the special symbol display area 9A in the same state. In the example shown in FIG. 14, characters are also displayed on the variable display unit 9. Hereinafter, the decorative design and the character may be collectively referred to as a decorative design.

  FIG. 15 is an explanatory diagram showing an example of a display control command transmitted from the main board 31 to the display control board 80 used in this embodiment. In this example, one display control command is composed of 2 bytes (CMD1, CMD2).

  As shown in FIG. 15, in this embodiment, a display control command that can specify a variable display period of a symbol, that is, a display control command that can specify a variable display pattern, a display control command that instructs the stop of all symbols, There are display control commands that indicate hits / offs depending on symbols. As shown in FIG. 15 (A), in this example, as a display control command capable of specifying a variable display period, “displacement”, “variation during probability change”, “reach 1”, “reach 2”, and “reach 3” There is.

  FIG. 16 is an explanatory diagram showing display control commands transmitted from the main board 31 to the display control board 80. As shown in FIG. 16, in this embodiment, the display control command is transmitted from the main board 31 to the display control board 80 through eight signal lines of display control signals CD0 to CD7. Between the main board 31 and the display control board 80, a signal line for the display control signal INT for transmitting a strobe signal, + 5V and + 12V supply lines for supplying power to the display control board 80, and a ground level are provided. Signal lines for supply are also wired.

  FIG. 17 is a timing chart showing an example of the transmission timing of the display control command given from the main board 31 to the game control board 80. In this example, the 2-byte display control data constituting the display control command data is sent every 2 ms as shown in FIG. Then, a strobe signal (display control signal INT) is output in synchronization with each display control data. Since the display control CPU 101 is interrupted at the rising edge of the strobe signal, the display control CPU 101 can capture each display control data by the interrupt processing program.

  Hereinafter, an example of the variation pattern of the special symbol and the decorative symbol will be described with reference to FIGS. FIG. 18 is a timing chart showing an example of a change in symbol when the reach is not reached. FIG. 19 is a timing chart showing an example of symbol variation during reach (when a big hit and not a big hit).

  In this embodiment, when a display control command indicating “displacement” is received from the main board 31, the display control CPU 101 can change the special symbol and the decorative symbol for 7 seconds as shown in FIG. indicate. However, in this embodiment, the decorative symbols are stopped in the order of the left symbol, the right symbol, and the middle symbol, and then the left symbol and the right symbol fluctuate for a while. The fluctuation of shaking means that a display is made such that the symbol is shaken up and down or left and right. The shaking variation is performed until the final stop symbol (determined symbol) is displayed.

  When the display control command indicating “stop all symbols” is received from the main board 31, the special symbols and the left and right decorative symbols are finally stopped (confirmed). That is, for the decorative symbols, the left and right decorative symbols are in a fixed state in which the left and right middle symbols are not moved. Note that the inner decorative pattern may also be swayed after the fluctuation due to the pattern c (deceleration) and then be in a finalized state. Further, in this case, the confirmed symbol of the special symbol is an off symbol, and the confirmed symbols of the left and right decorative symbols are such that the left symbol and the right symbol do not match.

  When receiving a display control command indicating “change during probability change” from the main board 31, the display control CPU 101 variably displays special symbols and decorative symbols for 4 seconds as shown in FIG. In this case, the special symbol and the decorative symbol are stopped simultaneously. In addition, the confirmed symbol of the special symbol is a disjoint symbol, and the confirmed symbol of the left and right decorative symbols is such that the left symbol and the right symbol do not match.

  When the variation shown in FIG. 18 (A) or (B) is performed, regarding the variation of the symbol from the main substrate 31 to the display control substrate 80, “displacement” or “probability variation” is displayed. Only the display control command to be displayed and the display control command to indicate “determine all symbols” are transmitted.

  While the symbols are changing, the display control CPU 101 performs display control so that a predetermined background is displayed, and performs display control so that a predetermined character is displayed on the screen and the character is appropriately exercised. . Specifically, the background and the character are notified to the VDP 103. Then, the VDP 103 creates the designated background image data. Also, image data of the instructed character is created and combined with the background image. Further, the VDP 103 synthesizes the image data of the special design and the image data of the decorative design in the left and right with the composite image. The VDP 103 also performs display control for moving the character and display control for changing the design. That is, the shape and display position of the character are changed according to a predetermined exercise pattern. Further, the symbol display position is changed according to the fluctuation speed notified from the display control CPU 101.

  In addition, the display control CPU 101 controls to replace and display the symbols that are several symbols before the confirmed symbol at a predetermined timing in order to confirm each ornamental symbol whose left and right symbols do not match in the left and right ornamental symbol display areas.

  FIG. 19A shows an example of a variation pattern displayed when a display control command “reach 1” is sent from the main board 31. When the reach control 1 is notified, the display control CPU 101 variably displays special symbols and decorative symbols for 15 seconds. The decorative design is stopped in the order of the left symbol, the right symbol, and the middle symbol, and then the left symbol and the right symbol are fluctuated for a while. The shaking variation is performed until the final stop symbol (determined symbol) is displayed.

  When a display control command indicating “stop all symbols” is received from the main board 31, the special symbols and the decorative symbols in the left and right are determined. That is, the state of fluctuation fluctuation of the left and right decorative symbols is terminated, and a fixed state in which the left and right middle symbols do not move is reached.

  FIG. 19B shows an example of a variation pattern displayed when a display control command “reach 2” is sent from the main board 31. When the reach control 2 is notified, the display control CPU 101 variably displays special symbols and decorative symbols for 29 seconds. As for the decorative symbols, the left symbol, the right symbol, and the middle symbol are stopped in this order, and then the left symbol and the right symbol fluctuate for a while. When a display control command indicating “stop all symbols” is received from the main board 31, the special symbols and the left and right decorative symbols are finally determined.

  FIG. 19C shows an example of a variation pattern that is displayed when a display control command of “reach 3” is sent from the main board 31. When the reach 3 is notified, the display control CPU 101 variably displays special symbols and decorative symbols for 40 seconds. As for the decorative symbols, the left symbol, the right symbol, and the middle symbol are stopped in this order, and then the left symbol and the right symbol fluctuate for a while. When a display control command indicating “stop all symbols” is received from the main board 31, the special symbols and the left and right decorative symbols are finally determined.

  When the symbols shown in FIGS. 19A to 19C are changed, the “reach 1”, “reach 2” or “reach 2” regarding the change of the symbols from the main board 31 to the display control board 80. A display control command of “reach 3”, a display control command indicating that the special symbol is stopped at “out” or “hit”, and a display control command indicating “stop all symbols” are transmitted.

  When receiving a display control command indicating that the special symbol is stopped at “hit”, the display control CPU 101 sets the special symbol fixed symbol as the winning symbol and aligns the decorative symbol fixed symbols in the left and right directions. Shall. Also, when receiving a display control command indicating that the special symbol is stopped by “off”, the display control CPU 101 sets the special symbol fixed symbol as the off symbol and aligns the decorative symbol fixed symbol left and right. Shall be.

  In FIG. 19, one type of variable display pattern is shown for each reach. However, a plurality of types of variable display patterns may be used for each reach. In this case, the display control CPU 101 determines which variable display pattern to use using a predetermined random number or the like.

  As described above, in this embodiment, only two types of “hit” and “off” are used as special symbols for determining whether or not to win. These symbols change at a constant speed (constant speed switching display) in any variable display pattern. However, decorative symbols with more symbols than the number of special symbols are variably displayed with various variation patterns, so that the game can be effectively produced and the interest of the game is not impaired. .

  Further, when the decorative symbol changes in synchronization with the change of the special symbol and the confirmed symbol of the special symbol is a winning symbol, the left and right decorative symbols are aligned. Further, when the confirmed symbol of the special symbol is an off symbol, the left and right middle decorative symbols are not aligned. When a reach operation (variation due to reach 1, 2 or 3) is performed, when the determined symbol of the special symbol is an off symbol, the left and right decorative symbols are aligned. Therefore, it is determined whether it is a big hit or not by a relatively simplified special symbol, but whether or not the player has won a big hit by the display result of the decorative symbol consistent with the display result of the special symbol Can be judged. Since the variation pattern of the decorative design can be made rich, the interest of the game is not reduced for the player.

  Further, even if the game effects by the decorative symbols are abundant, the number of commands sent from the main board 31 to the display control board 80 may be very small as shown in FIG.

Hereinafter, the control of the game control means and the display control means for realizing the display example described above will be described.
FIG. 20 is a flowchart showing all symbol variation start processing (step S304) in the special symbol process shown in FIG. When the variable display pattern is determined as to whether or not to win in the reach operation setting process in step S303, display control command transmission control for instructing them is performed. In step S304, the CPU 56 first Then, it waits for the completion of command transmission (step S304a). The command transmission completion is notified from the display control data output process (step S5) in the main process (see FIG. 6).

  In this embodiment, the CPU 56 sends to the display control board 80 a command that can specify the variable display pattern shown in FIG. In the case of reaching, a display control command indicating whether the special symbol is to be stopped by “off” or “hit” is sent to the display control board 80. Therefore, in the command transmission completion process in step S304a, it is confirmed whether or not transmission of all the commands has been completed.

  When the transmission of the display control command is completed, the CPU 56 starts a variation time timer for measuring the variation time notified to the display control board 80 (step S304b). Then, the special symbol process flag is updated so as to proceed to step S305 (step S304c).

  FIG. 21 is a flowchart showing the all symbol stop waiting process (step S305) in the special symbol process shown in FIG. In step S305, the CPU 56 checks whether or not the variable time timer has expired (step S305a). When the time is up, a display control command for instructing stop of all symbols is set (step S305b). Then, a display control command data transmission request is set (step S305c), and the special symbol process flag is updated so as to proceed to step S306 (step S305d). The display control command data transmission request is referred to in the display control data setting process (step S4) in the main process (see FIG. 6).

  As described above, in the special symbol process, the CPU 56 sends to the display control board 80 information that can specify the variable display pattern at the start of variation and information that indicates hit / displace by the special symbol, and the variation time timer. When the time is up, that is, when the instructed variation time is over, information indicating all symbol variations is sent to the display control board 80. During that time, the CPU 56 does not send a display control command related to symbol variation to the display control board 80. Therefore, the load required for the display control of the CPU 56 of the main board 31 is greatly reduced.

  FIG. 22 is a flowchart showing an operation example of the display control data setting process (step S4 in the main process shown in FIG. 6). In the display control data setting process, the CPU 56 first checks whether the data sending flag is set (step S411). If not set, it is checked whether or not the display control command data transmission request flag is set (step S412). If the transmission request flag is set, the transmission request flag is reset (step S413). Further, the display control command data to be sent is set in the output data storage area (step S414), and a port output request is set (step S416). The display control command data transmission request flag is set in the special symbol process. The data sending flag is set in the display control data output process described later.

  FIG. 23 is a flowchart showing the display control data output process (step S5) in the main process shown in FIG. In the display control data output process, the CPU 56 determines whether or not a port output request is set (step S421). If the port output request is set, the port output request is reset (step S422), and the contents of the port storage area (the first byte of the display control command) are output to the output port for sending the display control command ( Step S423). Then, the port output counter is incremented by 1 (step S424). Further, the INT signal is set to a low level (on state) (step S425), and the data sending flag is turned on (step S426).

  If the port output request is not set, it is determined whether or not the value of the port output counter is 0 (step S431). If the value of the port output counter is not 0, it is confirmed whether or not the value of the port output counter is 1 (step S432). When the value of the port output counter is 1, since the INT signal is turned off for the first byte of the display control command, the INT signal is turned off (= 1) (step S433). Also, the value of the port output counter is incremented by 1 (step S434).

  When the value of the port output counter is 2 (step S435), the output timing of the second byte of the display control command is reached, so the contents of the port storage area (second byte of the display control command) are output. (Step S436). Then, the port output counter is incremented by 1 (step S437). Further, the INT signal is set to a low level (step S438).

  When the value of the port output counter is not 2, that is, when it is 3, the INT signal OFF timing related to the second byte of the display control command is reached, so the value of the port output counter is cleared ( In step S441, the INT signal is turned off (high level) (step S442). Further, the data sending flag is turned off (step S443).

  In this embodiment, the display control data output process shown in FIG. 23 is executed once every 2 ms. Therefore, the data output process shown in FIG. 23 outputs 1 byte of data every 2 ms as shown in FIG.

Next, the operation of the display control CPU 101 will be described.
FIG. 24 is a flowchart showing main processing of the display control CPU 101. In the main process, the display control CPU 101 first initializes the RAM, the I / O port, the VDP 103, and the like (step S701). Then, display control is performed so that the initial screen appears on the variable display unit 9 (step S702). Thereafter, a random number update process (update process of a counter that generates a random number) is repeatedly executed (step S703).

  In this embodiment, actual variation control and the like are performed by timer interrupt processing. A timer interrupt occurs every 2 ms, for example. As shown in FIG. 25, in the timer interrupt process, the display control CPU 101 executes a display control process process (step S711). In the display control process process, a display control process corresponding to the value of the display control process flag is performed.

  A display control command from the main board 31 is received by the display control CPU 101 by an IRQ2 interrupt. FIG. 26 is a flowchart showing the IRQ2 interrupt process of the display control CPU 101. In the IRQ2 interrupt process, the display control CPU 101 first checks whether the data receiving flag is set (step S601). If not set, this interrupt is an interrupt caused by sending the display control data of the first byte in the display control command data. Therefore, the pointer is cleared (step S602), and a data receiving flag is set (step S603). Then, the process proceeds to step S604. The pointer indicates at which byte in the display control command data storage area in the RAM built in the display control CPU 101 the received data is stored.

  When the data reception flag is set, when the strobe signal is turned off (step S604), the display control CPU 101 inputs data from the input port and is indicated by the pointer in the display control command data storage area. Input data is stored in the address (step S605).

  Then, the display control CPU 101 increments the pointer value by 1 (step S606). If the value of the pointer becomes 2 (step S607), it means that the reception of the display control command data consisting of 2 bytes has been completed, so the data reception completion flag is set and data is being received. The flag is reset (steps S608 and S609). Through the processing as described above, the display control data CMD1 and CMD2 are received by the display control board 80.

  FIG. 27 is a flowchart showing the display control process (step S711) in the timer interrupt process shown in FIG. In the display control process process, any one of steps S720 to S870 is performed according to the value of the display control process flag. In each process, the following process is executed.

  Fluctuation start command reception waiting process (step S720): It is confirmed whether or not a display control command capable of specifying a variable display pattern has been received by an IRQ2 interrupt process.

  Decoration symbol stop symbol determination processing (step S750): A fixed symbol for the left and right ornament symbols is determined based on a predetermined random number. If multiple variation patterns are prepared for each reach (reach 1, reach 2, and reach 3), which pattern is used when the reach 1, reach 2 or reach 3 display control command is received. decide.

  All symbol variation start processing (step S780): Control is performed so that variation of the left and right middle symbols of the special symbol and the decorative symbol is started.

  Symbol variation processing (step S810): Controls the switching timing of each variation state (variation speed, background, character) constituting the variation pattern, and monitors the end of the variation time. Also, stop control (swing fluctuation start control) of the left and right symbols of the decorative symbol is performed.

  All symbol stop waiting setting process (step S840): When the display control command for instructing all symbol stops is received at the end of the variation time, the variation of the special symbol and the decorative symbol is stopped and the final stop symbol (determined symbol) is displayed. Control the display.

  Big hit display process (step S870): After the end of the fluctuation time, the control of the probability change big hit display or the normal big hit display is performed.

  FIG. 28 is a flowchart showing the variation start command reception waiting process (step S720). In the variation start command reception waiting process, the display control CPU 101 first checks whether or not a display control command capable of specifying a variable display pattern has been received (step S721). As shown in FIG. 15A, the display control command that can specify the variable display pattern is a command in which CMD1 is 80H and CMD2 is 01H, 2H, 03H, 04H, or 05H. When a display control command capable of specifying a variable display pattern is received, the value of the display control process flag is changed to a value corresponding to the decorative symbol stop symbol determination process (step S750) (step S722), and the monitoring timer Is started (step S723). The monitoring timer is a timer for monitoring whether or not the display control command “stop all symbols” is received.

  FIG. 29 is an explanatory diagram showing random numbers used by the display control CPU 101. In this embodiment, the display control CPU 101 uses random numbers 10 to 13. The random 10 is for determining a left / right middle fixed symbol of a decorative symbol when a big hit is generated by a special symbol. The random numbers 11 to 13 are for determining the left / right middle fixed symbol of the decorative symbol when the special symbol does not cause a big hit.

  FIG. 30 is a flowchart showing a decorative symbol stop symbol determination process (step S750). In the decorative symbol stop symbol determination process, the display control CPU 101 first confirms whether or not a display control command of “out” or “probability change” has been received (step S751). If either of them has been received, random 11 to 13 values are extracted, and the left / right middle fixed symbol of the decorative symbol is determined based on the extracted value (step S752). Specifically, the symbol number corresponding to the value of random 11 is the left determined symbol, the symbol number corresponding to the random 12 value is the medium fixed symbol, and the symbol number corresponding to the random 13 value is used. Is the right determined symbol (see FIG. 13). If the left and right determined symbols are the same, the right determined symbol is shifted by one symbol.

  If it is confirmed in step S751 that “displacement” and “variation during probability change” have not been received, the display control CPU 101 has received a display control command indicating that the special symbol is to be stopped at “winning”. (Step S753). When the display control command indicating that the game stops at “hit” is received, a random 10 value is extracted, and the left / right middle fixed symbol of the decorative symbol is determined based on the extracted value (step S754).

  When receiving a display control command indicating that the operation stops at “disconnect” in step S753, the display control CPU 101 extracts random 11 values and determines the left and right confirmed symbols of the decorative symbols based on the extracted values. (Step S755). In addition, a random 12 value is extracted, and a determined symbol is determined based on the extracted value (step S756). Here, when the left and right middle confirmed symbols are the same, the middle confirmed symbol is shifted by one symbol.

  When the final symbol of the decorative symbol is determined, the display control CPU 101 changes the value of the display control process flag to a value corresponding to the all symbol variation start process (step S780) (step S767).

  As described above, in this embodiment, the fixed design of the left and right decorative designs is determined by the display control means. Therefore, even if the number of decorative symbols is increased to increase the number of special effects while reducing the number of special symbols, the load related to display control of the game control means does not increase. Also, when determining the symbol of the decorative design, if the special symbol is confirmed with a winning symbol, it is determined with a combination of symbols reminiscent of a big hit, and if the special symbol is determined with a loss symbol, it is determined with a combination of symbols reminiscent of a loss. Determine. Therefore, the player can easily recognize whether the game is a big win or not based on the display result of the decorative symbols.

  FIG. 31 is a flowchart showing all symbol variation start processing (step S780). In the all symbol variation start processing, the display control CPU 101 determines to use a process table corresponding to the variable display pattern to be used (step S781). In the process table, each fluctuation state (fluctuation speed, fluctuation period at that speed, etc.) in the variable display pattern is set. The process table is set in the ROM.

  Then, the timer is started with the process timer value set at the beginning of the process table (step S782). Also, the design variation control and the background and character display control are started based on the data indicating the variation state set in the third byte (step S783). Then, the value of the display control process flag is changed to a value corresponding to the symbol variation processing (step S810) (step S784).

  FIG. 32 is an explanatory diagram of a configuration example of the process table. In each process table corresponding to each variable display pattern, a decorative symbol variation speed, a variation period at the velocity, a background and a character switching timing, and the like are set in time series. In addition, a process timer value for determining a fluctuation period at a certain speed is also set. Each process table is composed of a plurality of process data in units of 3 bytes.

  For example, in the process table corresponding to the variable display pattern shown in FIG. 18A, for the first process data (3 bytes), the change of the special symbol is started and the left and right middle symbols of the decorative symbol are displayed at low speed. A process timer value indicating the time until the next display state switching timing is set. This is because the first variation is variation (acceleration) due to pattern a, and first, low-speed variation should be started.

  Thereafter, how the display state is switched and a process timer value indicating the time until the next display state switching timing are sequentially set. The display state switching timing is the timing for switching the display pattern for special symbols and the timing for switching the changing speed of either the left or right middle symbol for decorative symbols. The timing to be included is also included.

  Therefore, the display control CPU 101 can know that some display state must be changed as the process timer expires. The display state to be changed can be known from the setting value of the third byte of the next process data in the process table.

  FIG. 33 is a flowchart showing the symbol variation processing (step S810). In the symbol variation process, the display control CPU 101 checks whether or not the process timer has timed out (step S811). If the process timer has timed out, the pointer indicating the data in the process table is incremented by 3 (step S812). Then, it is confirmed whether or not the data in the area pointed to by the pointer is an end code (step S813). If it is not an end code, the symbol variation control, the background and character display control are changed based on the data indicating the variation state set in the third byte of the process data pointed to by the pointer (step S814). The timer is started with the process timer value set in the byte (step S815).

  If it is an end code in step S813, the value of the display control process flag is changed to a value corresponding to the all symbol stop waiting process (step S840) (step S816).

  FIG. 34 is a flowchart showing the all symbol stop waiting process (step S840). In the all symbol stop waiting process, the display control CPU 101 checks whether or not a display control command instructing “stop all symbols” has been received (step S841). If the display control command for instructing all symbols to be stopped is received, control is performed to stop the left and right decorative symbols with the determined symbols that have been determined (step S842). Also, control is performed to stop the special symbol at the final symbol (step S843). Then, the value of the display control process flag is set to a value corresponding to the jackpot display process (step S870) (step S844).

  If the display control command designating “stop all symbols” has not been received, it is confirmed whether or not the monitoring timer has timed out (step S845). If time-out occurs, it is determined that some abnormality has occurred, and control is performed to display an error screen on the variable display unit 9 (step S846).

  FIG. 35 is an explanatory diagram showing a display example of the variable display section 9 when a symbol is determined. (A) shows the case of losing, and (B) shows the case of winning. As shown in FIG. 35 (A), a special symbol display area 9A displays an off symbol, and a decorative symbol display area 9B displays a confirmed symbol whose left and right middle symbols do not match. Further, as shown in FIG. 35 (B), when a symbol is displayed in the special symbol display area 9A, a confirmed symbol in which the left and right middle symbols match is displayed in the decorative symbol display area 9B.

  When the CPU 56 of the main board 31 decides that the probability variation is a big hit, in order to notify the player of that, for example, a dedicated display means is provided on the game board, and the probability variation big hit is provided on the display means. It may be displayed that has occurred.

  In addition, information indicating whether or not a probable big hit may be added to the display control command sent from the main board 31 to the display control board 80. FIG. 36 is an explanatory diagram showing a configuration example of a display control command to which information indicating whether or not the probability variation big hit is added. The command indicating the variable display pattern and the command indicating “stop all symbols” are as shown in FIG.

  In this case, in the process shown in FIG. 9, when the CPU 56 of the main board 31 decides to make a probable big hit (step S68), the command [8BH, 03H] shown in FIG. 36 is displayed on the display control board. Send to 80. Otherwise, the command [8BH, 02H] is sent to the display control board 80.

  In this example, in the case of a probable big hit, the fixed symbol of the decorative symbol is “one”, “three”, “five”, “seven”, “nine” or “geta”. In the case of a big hit that does not change with certainty, the determined symbol of the decorative symbol is set as the other symbol.

  FIG. 37 is a flowchart showing the decorative symbol stop symbol determination process (step S750) in this example. In this case, when the command [8BH, 03H] is received, the left / right middle fixed symbol of the decorative symbol is determined using the symbol table of the decorative symbol (for probability variation) according to the value of 10 at random (steps S753, S761, S762). When the command [8BH, 02H] is received, the left / right middle fixed symbol of the decorative symbol is determined using the symbol table of the decorative symbol (for non-probability change) according to a random value of 10 (steps S753, S761, S763).

  In the design table of decorative design (for probability variation), there is a correspondence between each value that can be taken by random 10 and the decorative design “one”, “three”, “five”, “seven”, “nine”, “geta” Is set. In addition, in the design table of decorative designs (for non-probability variation), each value that can be taken by random 10 and decorative designs “two”, “four”, “six”, “eight”, “ten”, “rice ball” Correspondence is set. Therefore, when it is a probable big hit, the definite symbols of the left and right decorative designs will be one of “one”, “three”, “five”, “seven”, “nine”, “clogs” and will not be a probable big hit In some cases, the fixed symbols of the left and right decorative designs are “two”, “four”, “six”, “eight”, “ten”, and “rice ball”.

  FIG. 38 is an explanatory diagram showing a display example at the time of symbol determination in the case of big hit that is not probable and the case of probable big hit. As shown in FIG. 38 (A), when it is not a probable big hit, a special symbol display area 9A displays a winning symbol, and the decorative symbol display area displays, for example, “two” as a fixed symbol of the decorative symbol. ing. As shown in FIG. 38B, in the case of a probable big hit, a special symbol display area 9A displays a winning symbol, and the decorative symbol display area displays, for example, “seven” as a fixed symbol for the decorative symbol. It is displayed.

  At the same time, a probability variation display area 9C is displayed on the variable display section 9. If the probability variation big hit is not displayed, the probability variation display area 9C is turned off, and if the probability variation big hit, the probability variation display area 9C is lit. Is displayed.

  As described above, if the determined symbols of the decorative symbols are made different depending on whether or not the probability variation jackpot is different, the player can easily confirm whether or not the probability variation jackpot has occurred. Even when such display control of decorative symbols is performed, the game control means does not perform the decorative symbol determination process, and determines the fixed symbols of the decorative symbols on the display control means side. Therefore, the load required for display control of the game control means does not increase.

  In this example, the decorative design is made different and the probability variation display area 9C is notified of whether or not the probability variation is a big hit. However, only the decorative design is made different or whether the probability variation display area 9C is a probability variation big hit or not. Even if only the notification is made, it is possible to notify the player whether or not it is a probable big hit.

  In each of the embodiments described above, two types of symbols that are different from the winning symbol are used as the special symbols. However, the number of symbols may be further increased in a range smaller than the total number of decorative symbols. In the display example of the variable display unit 9 shown in FIG. 39, for example, eight types of special symbols as shown in FIG. 40 are variably displayed in the special symbol display area 9A. The symbol switching speed in the variable display is constant. For example, “3” is used as a winning symbol.

  When the display control CPU 101 receives the display control command indicating the variable display pattern of the reach operation from the main board 31, the display control CPU 101 starts the change of the special symbol and the decorative symbol, and receives the display control command for stopping the special symbol at “hit”. In this case, the special symbol variable display is stopped at “3”. At this time, the fixed symbols of the decorative symbols are aligned in the left and right. In addition, when a display control command for stopping the special symbol at “off” is received, variable display of the special symbol is stopped at other than “3”. At this time, the fixed symbols of the decorative symbols are aligned left and right.

  Even in such a configuration, the command [8BH, 03H] corresponding to the probability variation jackpot and the command [8BH, 02H] which is not so may be separated. For example, when the command [8BH, 03H] is received, the determined symbol of the special symbol is set to “7”, and when the command [8BH, 02H] is received, the determined symbol of the special symbol is divided into “3”. You may do it.

  In the above embodiment, the following gaming machines are also disclosed.
