Description

Technical Field

[0001] The present invention relates to a pachinko gaming machine.

Background Art

[0002] Generally, when a game ball enters a starting port in a pachinko gaming machine, a random number value for lottery is obtained, and this is temporarily stored as an activated hold ball up to a predetermined upper limit number. Such activated hold balls are sequentially consumed one by one every time a predetermined starting condition is satisfied, and a win / loss determination as to whether or not it corresponds to a big win is executed. If the result of the win / loss determination is a big win, after variably displaying a decorative pattern consisting of a plurality of columns, the decorative pattern is stopped and displayed in a predetermined winning mode, and a special game is established in which a big winning port that is normally in a closed state is opened.

[0003] In this type of pachinko gaming machine, there is known one that executes a game effect for suggesting or notifying the degree of expectation of shifting to a special game by using a predetermined effect device (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] Since there are already many pachinko gaming machines adopting such a configuration as conventional models, in order to differentiate from the conventional models, further improvement in the interestingness of the game is required.

[0006] The present invention has been made in view of such problems, and an object thereof is to provide a pachinko gaming machine capable of improving the interestingness of the game.

Means for Solving the Problems

[0007] For achieving such an object, the pachinko gaming machine according to the present invention includes a game board on which a game area is formed, a starting port provided in the game area through which a game ball can enter, a win / loss determination means for performing a win / loss determination triggered by the entry of the game ball into the starting port, a special symbol display device for variably displaying and stoppingly displaying a special symbol indicating the result of the win / loss determination, a big winning port provided in the game area that is opened according to the result of the win / loss determination by the win / loss determination means and through which the game ball can enter, a special game execution means capable of executing a special game involving the opening of the big winning port when the result of the win / loss determination by the win / loss determination means is a big win, and an effect display device for displaying an effect display. It is possible to execute a standby effect when a predetermined condition is satisfied in a situation where the variable display of the special symbol is not being executed, and it is possible to display a caution display that prompts a predetermined caution to the player. During the execution of the standby effect, the caution display can be displayed in a first mode, and during the execution of the special game, the caution display can be displayed in a second mode different from the first mode. During the execution of the standby effect, it is possible to display a gaming machine identification display that is a display regarding predetermined identification information capable of identifying the model of the gaming machine. During the execution of the special game, when displaying the caution display in the second mode, the caution display in the second mode can be displayed simultaneously with a specific image, while during the execution of the standby effect, when displaying the caution display in the first mode, the caution display in the first mode is configured not to be displayed simultaneously with the specific image. It is possible to execute a predetermined character effect for displaying a predetermined character during the variable display. As a character effect corresponding color that is the color of the character itself or the color around the character displayed in the predetermined character effect, it has a first color and a second color. As the character effect corresponding color in the predetermined character effect, the case where the second color is displayed has a higher expectation level of transitioning to the special game than the case where the first color is displayed. As the display color of the caution display, it is configured not to display at least the second color.

Mode for Carrying Out the Invention

[0010] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0011] [First Embodiment] The front view and rear view of the pachinko gaming machine PM according to this embodiment are shown in FIGS. 1 and 2. First, with reference to these figures, the overall configuration of the pachinko gaming machine PM will be outlined. Note that the pachinko gaming machine PM according to this embodiment is a model in which two functions corresponding to the conventional first - type pachinko gaming machine are mixed, and the first game (first special symbol game) and the second game (second special symbol game) can be developed.

[0012] <Basic Configuration of Pachinko Gaming Machine> First, with reference to FIG. 1, the basic structure on the front side of the pachinko gaming machine PM will be described. As shown in FIG. 1, the pachinko gaming machine PM (also simply referred to as "gaming machine PM") has a front frame 2 configured in a rectangular frame size that forms an opening and closing mounting frame, which is attached to the front opening surface of an outer frame 1 that forms a vertical fixed holding frame configured in an outer rectangular frame size, so as to be horizontally opened, closed, and detachably attached by upper and lower hinge mechanisms 3 disposed on the front left edge portions of each other, and is always held in a closed state engaged and connected to the outer frame 1 by using a locking device 4 called a double lock provided on the front right edge portion.

[0013] On the front frame 2, a square glass frame 5 that matches the upper front area of the front frame 2 is assembled so as to be horizontally opened, closed, and detachably attached by using upper and lower hinge mechanisms 3, and is always held in a closed state covering the front surface of the front frame 2 by using the locking device 4. A game board 20 is detachably set and held on the front frame 2, and is configured to face the game area PA on the front of the game board 20 so as to be visible through the multilayer glass of the glass frame 5 that is always closed and held.

[0014] On the front side of the glass frame 5, a frame lamp (LED lamp) 10 that emits light according to the progress of the game and a speaker 11 that generates sound effects according to the progress of the game are provided. Upper and lower ball trays (upper ball tray 8 and lower ball tray 9) for storing game balls are provided at the lower part of the glass frame 5. An effect button (effect switch) 15 that is pressed by the player is provided at the center of the front surface of the upper ball tray 8, and a firing handle 12 for performing a firing operation of the game ball is provided on the front right side of the lower ball tray 9. Hereinafter, for convenience, the operation input means for effects is referred to as "effect button 15", but the effect button 15 in this example refers to a concept including all operation input means such as an on / off operation type button-type switch, a cross-type switch (cross key, cross button) that outputs according to the direction of operation input, a tilt operation type lever-type switch, a rotary operation type dial switch, a proximity switch that outputs when the player's hand approaches or touches, a touch sensor, and a touch panel.

[0015] The game board 20 is configured based on a substrate formed in a rectangular flat plate shape using a synthetic resin material such as acrylic resin, polycarbonate resin, or ABS resin. On the front surface of the game board 20, an outer rail 41 and an inner rail 42 are fixedly provided in an arc shape, and a substantially circular game area PA in which game balls can roll is demarcated. Further, a guide passage (not shown) for guiding the game balls to the game area PA is formed by the outer rail 41 and the inner rail 42, and at a position near the outlet opening of the game balls in this guide passage (at the tip of the inner rail 42), a ball return prevention valve 43 for preventing the game balls discharged from the outlet opening into the game area PA from returning to the guide passage again is disposed. In this game area PA, in addition to various winning openings such as a windmill, a large number of game nails, a first starting port 51, a second starting port 52, an operating gate 53, a big winning opening 54, and general winning openings 61, 62, 63, 64, various display devices such as a first special symbol display device 71, a second special symbol display device 72, a first special figure holding lamp 73, a second special figure holding lamp 74, a normal symbol display device 75, and a normal figure holding lamp 76 are provided. A center ornament 21 is disposed substantially at the center of the game area PA, and the screen of the effect display device 70 is provided so as to be visible through the central opening of this center ornament 21.

[0016] The game area PA is divided into a left area PA1, which is the area on the left side of the center decoration 21 (the board area corresponding to left-handed play) and a right area PA2, which is the area on the right side of the center decoration 21 (the board area corresponding to right-handed play), with the center decoration 21 in the approximate center as a reference. Above the center decoration 21, a top plate portion 22 that faces the outer rail 41 in a substantially vertical direction is integrally formed, and a communication passage 44 through which the game ball can pass from between the top plate portion 22 and the outer rail 41 to the right area PA2 is formed on the extension of the above-described guide passage. In the present embodiment, the game balls flowing down in the left area PA1 can mainly enter any one of the first starting port 51 disposed below the center decoration 21 and the general winning ports 61 to 63. On the other hand, the game balls flowing down in the right area PA2 can mainly enter any one of the operating gate 53 disposed to the right of the center decoration 21, the general winning port 64, the second starting port 52, and the big winning port 54. At the lower end of the game area PA, an out port 29 for discharging the game balls that have rolled down without entering each winning port to the back side of the game board 20 is provided. Hereinafter, each component provided on the game board 20 will be described in order.

[0017] The first starting port 51 is provided as a starting winning port corresponding to the first special symbol game and includes a first starting port switch 511 for detecting the entry of a game ball. This first starting port 51 is an upwardly open and always open winning port, and mainly game balls (left-handed game balls) flowing down in the left area PA1 can enter. The entry of a game ball into the first starting port 51 triggers the first special symbol lottery. In the present embodiment, the special symbol that is variably displayed or stopped in the first special symbol display device 71 is referred to as the "first special symbol".

[0018] The second start port 52 is provided as a start winning port corresponding to the second special symbol game, and includes a second start port switch 521 for detecting the entry of a game ball. This second start port 51 is disposed in the right area PA2 which is a board area corresponding to a right hit, and game balls flowing down mainly in the right area PA2 (game balls hit on the right) can enter. The entry of a game ball into the second start port 52 triggers the second special symbol lottery. In the present embodiment, the special symbol variably displayed or stopped displayed on the second special symbol display device 72 is referred to as the "second special symbol". This second start port 52 generally includes a normal electric accessory 522 called a "denchu", and a normal electric accessory solenoid 523 for driving the normal electric accessory 522 to open and close. The normal electric accessory 522 can be changed between an open state where a game ball can enter or enter easily, and a closed state where a game ball cannot enter or enter with difficulty into the second start port 52. That is, the normal electric accessory 522 has a structure in which it is difficult for a game ball to enter the second start port 52 unless it is displaced to the open state, and when it becomes the open state at a predetermined opportunity (the opportunity to win the normal symbol lottery) described later, the ease of entry of the game ball increases. This normal electric accessory 522 includes a front and rear slide type movable member 524 for opening and closing the second start port 52. The movable member 524 can slide in the front and rear direction (the direction perpendicular to the board surface) between a closed position (a protruding position) that closes the second start port 52 and makes it impossible or difficult for a game ball to enter, and an open position (a retracted position) that opens the second start port 52 and makes it possible or easy for a game ball to enter. The upper surface of this movable member 524 has a passage width of about one or more game balls in the front and rear direction, and is formed to be inclined downward from the right side to the left side in a front view. Therefore, when the movable member 524 is in the closed position (when the second start port 52 is in the closed state), the game ball can flow down with the upper surface of the movable member 524 as a guide path, flow down from the right side to the left side on the guide path, and fall from the left end of the normal electric accessory 522.

[0019] The operating gate 53 is provided as a start winning port corresponding to the normal symbol game, and includes an operating gate switch 531 for detecting the passage of a game ball. The passage of a game ball through the operating gate 53 triggers the normal symbol lottery for determining whether or not to open the second start port 52.

[0020] The big winning opening 54 is formed as a horizontally rectangular winning opening that becomes open when the winning or losing lottery result of the first special symbol or the second special symbol is a big win or a small win. The big winning opening 54 includes a big winning opening switch 541 for detecting the entry of a game ball, a special electric accessory 542 generally called an attacker, and a big winning opening solenoid 543 for driving the opening and closing of this special electric accessory 542. The special electric accessory 542 can be changed between an open state where a game ball can enter or easily enter, and a closed state where a game ball cannot enter or has difficulty entering the big winning opening 54. In this example, the big winning opening 54 is provided in the right region PA2 in the game area PA. Therefore, in a special game (big win game, small win game), when firing a game ball, by aiming at the right region PA2 and making a so-called right shot, it is easy for the game ball to enter the big winning opening 54.

[0021] The general winning openings 61 to 63 are arranged in the left region PA1 which is a board surface area corresponding to a left shot, and game balls flowing down in the left region PA1 can enter. The general winning openings 61 to 63 are provided with a left general winning opening switch 611 for detecting the entry of a game ball. This left general winning opening switch 611 is configured as a common sensor (single sensor) for the three general winning openings 61 to 63 from the perspective of cost reduction and the like, and it is possible to detect the entry of a game ball into any of the general winning openings 61 to 63.

[0022] The general winning opening 64 is arranged in the right region PA2 which is a board surface area corresponding to a right shot, and game balls flowing down in the right region PA2 can enter. The general winning opening 64 is provided with a right general winning opening switch 641. Note that the entry of a game ball into each of the general winning openings 61 to 64 does not trigger the lottery of the special symbol or the normal symbol, but it becomes an opportunity to obtain a prize ball in the same way as other winning openings (excluding the operating gate 53).

[0023] The first special symbol display device 71 performs variable display and fixed display of the first special symbol when a game ball enters the first start port 51. This first special symbol display device 71 is composed of, for example, eight LED lamps. The variable display of the first special symbol is expressed according to the blinking pattern of the lamps, and the first special symbol is fixed and displayed when the blinking of the lamps stops and switches to a lit display.

[0024] The second special symbol display device 72 performs variable display and fixed display of the second special symbol when a game ball enters the second start port 52. This second special symbol display device 72 is composed of, for example, eight LED lamps. The variable display of the second special symbol is expressed according to the blinking pattern of the lamps, and the second special symbol is fixed and displayed when the blinking of the lamps stops and switches to a lit display.

[0025] The first special symbol hold lamp 73 and the second special symbol hold lamp 74 are each composed of, for example, two LED lamps, and the number of operation hold balls (up to four each) of the first special symbol and the second special symbol is expressed by the lighting and blinking display of the lamps. The number of operation hold balls of the first special symbol is a number related to the random number value obtained based on the entry of a game ball into the first start port 51 during the variation of the first special symbol or the second special symbol or during the execution of a big win game, and the obtained random number value is held, that is, it indicates the number for which the validity determination has been temporarily held until the validity determination permission condition (variation start condition) for the obtained random number value is satisfied. Similarly, the number of operation hold balls of the second special symbol is a number related to the random number value obtained based on the entry of a game ball into the second start port 52 during the variation of the first special symbol or the second special symbol or during the execution of a big win game, and the obtained random number value is held, that is, it indicates the number for which the validity determination has been temporarily held until the validity determination permission condition (variation start condition) for the obtained random number value is satisfied.

[0026] The normal symbol display device 75 is composed of, for example, two LED lamps and performs the variable display and the determined display of the normal symbol. The general symbol hold lamp 76 is composed of, for example, four lamps, and the number of lit lamps corresponds to the number of holds of the normal symbol variation (the number of normal symbol variations that have not been executed yet). Note that on the left side of the normal symbol display device 75, a round display 77 for displaying the number of rounds (round number: the number of times the special electric accessory 542 operates continuously) in the big win game is provided.

[0027] The effect display device 70 mainly displays an effect image including a variation effect of a decorative symbol that variably displays and stops in conjunction with the first special symbol or the second special symbol, and a preview effect that pre-announces or notifies the degree of expectation of a big win, and performs a hold display corresponding to the hold balls of the first special symbol and the second special symbol. Specifically, on the screen of the effect display device 70, a decorative symbol display area 700 where a variable display of a decorative symbol, a preview effect display, etc. are executed, a hold image display area 710 where hold images of the first special symbol and the second special symbol are displayed in synchronization with the first special symbol hold lamp 73 and the second special symbol hold lamp 74, and a mid-variation image display area 720 where a mid-variation image corresponding to the current variable display is displayed are provided. In the present embodiment, a liquid crystal display device is adopted as the effect display device 70. In the decorative symbol display unit 700, three display areas (left symbol display area Z1, middle symbol display area Z2, right symbol display area Z3) that serve as variable display areas of the decorative symbol are provided on a predetermined effective line (not shown), and the left symbol of the decorative symbol, the middle symbol of the decorative symbol, and the right symbol of the decorative symbol are respectively stopped and displayed corresponding to the left symbol display area Z1, the middle symbol display area Z2, and the right symbol display area Z3. In the hold image display unit 710, a hold image (hold icon) corresponding to the hold ball of the first special symbol and a hold image (hold icon) corresponding to the hold ball of the second special symbol are displayed. The hold images are displayed in order according to the generation order (incoming ball order) of the hold balls of the special symbols, and a maximum of four hold images of the first special symbol and a maximum of four hold images of the second special symbol can be displayed. Also, in the mid-variation image display area 720, a mid-variation image (mid-variation icon) corresponding to the current variable display being executed is displayed.

[0028] The center ornament 21 is installed around the effect display device 70 and has functions such as guiding the flow path of game balls, protecting the effect screen, and decoration. The center ornament 21 is provided with a movable accessory 24 that executes an effect operation according to the progress of the game. The movable accessory 24 is configured to include a motor M (for example, a stepping motor) as a drive source. In addition, the game board 20 is provided with a board lamp (LED lamp) 25 that emits light according to the progress of the game. In the following description, for convenience, the frame lamp 10 and the board lamp 80 are also collectively referred to as the "effect lamp LP".

[0029] Subsequently, while referring to FIG. 2, the basic structure on the back side of the pachinko machine PM will be described. On the back side of the front frame 2, a back set board 30 is formed based on a base frame body that has a window communicating front and back at the center and is formed in a somewhat smaller rectangular frame shape than the front frame 2. The back set board 30 is connected to the rear of the front frame 2 via upper and lower hinge mechanisms 3 so as to be capable of being opened and closed laterally and attached and detached. A back set cover 30C having a rectangular box shape with an open front is detachably attached to the back set board 30, and is always disposed so as to cover the back side of the game board 20 attached to the front frame 2 (thereby, the main control board 100, the effect control board 200, and the image control board 300 described later are covered by the back set cover 30C).

[0030] Each part of the back set board 30 is provided with a storage tank 31 for storing a large number of game balls, a tank rail 32 that extends from the storage tank 31 to the right with a gentle downward slope, a ball supply passage portion 33 that is connected to the right end portion of the tank rail 32 and extends downward, a prize ball payout unit 34 that pays out the game balls guided by the ball supply passage portion 33, a prize ball passage portion 35 for guiding the game balls paid out from the prize ball payout unit 34 to the upper ball tray 6, and the like.

[0031] On the back side of the game board 10, there are installed a main control board 100 that comprehensively controls the operation of the pachinko gaming machine PM, a production control board 200 that controls all productions, an image control board 300 that controls image display and sound effects according to the game progress, and so on. On the contrary, on the back side of the back set board 30, there are installed a payout control board 400 that controls the launch and payout of game balls, a power supply board 500 that receives power from the game facility side and supplies power to various control boards and electrical and electronic components, an external information terminal board 600 (see Fig. 3) that outputs an external information signal (outer end signal) to the outside of the gaming machine PM, and so on. These control boards are respectively arranged at predetermined positions on the back side of the game board 20 or the back side of the back set board 30 in an assembled state accommodated in a substrate case made of transparent resin having a caulking structure and a sealing tape structure for preventing unauthorized modification. These control boards and the electrical and electronic components of each part of the pachinko gaming machine PM are interconnected via a harness (connector cable), and the pachinko gaming machine PM is configured to be operable.

[0032] <Control Configuration of Pachinko Gaming Machine> Next, with additional reference to Fig. 3, each control board mounted on the pachinko gaming machine PM according to the present embodiment will be described. Fig. 3 is a control block diagram showing the control configuration of the pachinko gaming machine PM.

[0033] The main control board 100 is equipped with a main control microcomputer (one-chip microcomputer) 110 configured with a main CPU 101 that performs various arithmetic processes related to the game, a ROM 102 that stores control programs and various data, a RAM 103 that functions as a work area and buffer memory serving as a temporary storage area, and an I / O port circuit 104 that inputs and outputs signals between peripheral boards and each device. The main CPU 101 is configured to execute main control related to game progress according to the control program stored in the ROM 102. In addition, although not shown in the figure, the main control board 100 is equipped with a clock circuit that divides the clock signal from the crystal oscillator to generate an internal system clock, a WDT circuit that resets the main CPU 101 when it malfunctions or runs wild and returns it to a normal state, a CTC circuit that enables the generation of real-time interrupts and time measurement, and a random number generation circuit that operates as a separate system from the program processing (software random numbers) by the main CPU 101 to generate a predetermined random number (built-in random number). These are interconnected via an internal bus.

[0034] Based on detection information from each switch, etc., the main CPU 101 reads out various control programs stored in the ROM 102 and performs arithmetic processes to execute various processes related to the main control of the game. The RAM 103 is a backup RAM as a non-volatile storage means backed up by the backup power generated on the power supply board 500. The backup area of the RAM 103 is an area for storing data such as the stack pointer and each register held at the time of power-off in the event of a power failure. When the power is turned on (when power failure is restored), the state of the gaming machine is restored to the state before the power failure based on the information in the backup area.

[0035] In addition, the main control board 100 is electrically connected to a first start port switch 511, a second start port switch 521, an operating gate switch 531, a big winning port switch 541, a left general winning port switch 611, a right general winning port switch 641, etc., and inputs detection signals from various switches to the main CPU 101 via the I / O port circuit 104. Also, the main control board 100 is electrically connected to a first special symbol display device 71, a second special symbol display device 72, a first special figure hold lamp 73, a second special figure hold lamp 74, a normal symbol display device 75, and a normal figure hold lamp 76, and is also electrically connected to a normal electric accessory solenoid 523 and a special electric accessory solenoid 543, and transmits control signals from the main CPU 101 to various display means and various solenoids via the I / O port circuit 104. Further, the main control board 100 is electrically connected to an external information terminal board 600, and transmits a game information signal from the main CPU 101 to the external terminal board 600 via the I / O port 104. Based on the game information signal transmitted from the main control board 100, this external information terminal board 600 transmits various external information signals to external devices (data display, hall computer, etc.) installed outside the gaming machine PM. Note that the game information signal transmitted from the main control board 100 may be input to the external information terminal board 600 via, for example, a payout control board 300 or the like.

[0036] The main control board 100 and the effect control board 200 are connected by eight parallel signal lines and one strobe line, and are communicably connected in only a single direction from the main control board 100 to the effect control board 200, and various effect control commands are transmitted from the main control board 100 to the effect control board 200. Data cannot be transmitted from the effect control board 200 to the main control board 100, and the effect control board 200 cannot request data transmission to the main control board 100.

[0037] The performance control board 200 is equipped with a sub-main CPU 201 that performs various arithmetic processes related to game performances based on performance control commands from the main control board 100, a ROM 202 that stores a performance control program and various data, a RAM 203 that functions as a work area and buffer memory for a temporary storage area, and an I / O port circuit 204 that inputs and outputs signals to and from peripheral boards and each device. It is equipped with a performance control microcomputer (one-chip microcomputer) 210 configured such that the sub-main CPU 201 executes main control related to game performances according to the control program stored in the ROM 202. In addition, although not shown in the figure, the performance control board 200 is equipped with a clock circuit that divides a clock signal from a crystal oscillator to generate an internal system clock, a WDT circuit that resets the sub-main CPU 201 when it malfunctions or runs wild and returns it to a normal state, a TPU circuit that outputs various signals based on the system clock, an interrupt controller that activates various interrupts such as timer interrupts based on signals from the TPU circuit, a serial communication circuit for inputting and outputting serial data, etc. These are interconnected via an internal bus.

[0038] The performance control board 200 generates an image control command for instructing an image and sound to the image control board 300, a lamp control signal (lamp data) for controlling the lamp connection board 91, a drive control signal (drive data) for controlling the motor driver 92, etc. in performance control processing based on a performance control command from the main control board 100. The performance control board 200 is connected to the image control board 300 such that two-way communication is possible. While an image control command regarding an image and sound is transmitted from the performance control board 200 to the image control board 300, as a response, a response command (ACK command) indicating that this image control command has been received normally is transmitted from the image control board 300 to the performance control board 200.

[0039] In addition, the effect control board 200 is electrically connected to a lamp connection board 91 equipped with a plurality of LED drivers, and transmits a lamp control signal (lamp data) for controlling the lamp connection board 91 via a serial communication circuit. In this example, clock-synchronous serial communication is adopted between the effect control board 200 and the lamp connection board 91, and the lamp control signal is transmitted bit by bit via the data line in synchronization with a clock signal transmitted via a signal line (clock line) different from the data line for lamp data transmission. The lamp connection board 91 incorporates an LED driver that functions upon receiving the lamp control signal for LED driving transmitted from the effect control board 200, and supplies or cuts off a driving current to the effect lamp LP by switching on / off a switch in the circuit, thereby performing control to turn on or off the effect lamp LP.

[0040] Furthermore, the effect control board 200 is electrically connected to a plurality of motor drivers 92, and transmits a drive control signal (drive data) for controlling the motor drivers 92 to the motor drivers 92 via the I / O port circuit 204. The motor drivers 92 supply or cut off a driving current to the stepping motors of the respective movable fixtures 24 by switching on / off a switch in the circuit based on the drive control signal for fixture driving transmitted from the effect control board 200, thereby performing control to operate the respective movable fixtures 24. Note that parallel communication is adopted for data transmission to the motor drivers 92.

[0041] The image control board 300 is equipped with a sub-sub CPU 301 that performs various arithmetic processes related to image effects based on image control commands from the effect control board 200, a ROM 302 that stores an image control program, various data, etc., a RAM 303 that functions as a work area and buffer memory serving as a temporary storage area, and an I / O port circuit 304 that inputs and outputs signals between peripheral boards and each device. It is configured to mount an image control microcomputer (one-chip microcomputer) 310. The sub-sub CPU 301 is configured to execute main control related to image effects according to the control program stored in the ROM 302. In addition, although not shown in the figure, the image control board 300 is equipped with a VDP that generates image data along with the effect content based on the control signal acquired from the sub-sub CPU 301, and a sound source IC that generates acoustic data along with the effect content based on the control signal acquired from the sub-sub CPU 301. The VDP is a so-called image processor. It reads the image data stored in the image ROM in response to an instruction from the sub-sub CPU 301, processes this data, and transmits the generated video signal (image data) to the effect display device. A high-speed VRAM used for the expansion and processing of the image data read from the image ROM is connected to this VDP. The sound source IC reads the acoustic data stored in the voice ROM in response to an instruction from the sub-sub CPU 301, synthesizes this data, and outputs the generated acoustic data to the speaker 11 via an amplifier (digital amplifier).

[0042] The payout control board 400 is mainly composed of a payout CPU 401, a ROM 402, and a RAM 403. The payout control board 400 is connected to the main control board 100 so as to enable two-way communication. Based on the payout control command from the main control board 100, it executes control to drive the prize ball payout unit 34 to pay out prize balls. At the same time, based on the operation amount of the launch handle 12, it synchronously drives the ball feeding mechanism 13 and the launch mechanism 14 to execute control of the launch of the game balls.

[0043] Although detailed illustration is omitted, the power supply board 500 includes a normal power supply circuit for generating the normal power supply used in each control board based on the primary power supply supplied from the power supply equipment of the gaming island, a backup power supply circuit for generating a backup power supply, and a power failure monitoring circuit for monitoring power failure due to voltage drop. It supplies the power required for electronic and electrical components such as each control board and gaming equipment. A power switch for activating the power supply circuit is connected to the power supply board 500. On the premise that the primary power supply is supplied from the power supply device of the gaming island, when the power switch is turned on, a predetermined power supply is supplied from the normal power supply circuit of the power supply board 500 to each control board and the like. The power supply board 500 is configured to be able to detect that the power supply from the power supply device of the gaming island has been cut off, and when a power failure is detected, it transmits a power failure signal (NMI signal) indicating that fact to the main control board 100, the effect control board 200, and the payout control board 400. The backup power supply circuit is configured to be charged when power is supplied from the power supply device of the gaming island to the pachinko game machine PM. In addition, a RAM clear switch (not shown) for once erasing the temporarily stored content of the RAM 103 of the main control board 100 and setting an initial value is connected to the power supply board 500 when the pachinko game machine PM is powered on. The RAM clear switch may be connected to, for example, the main control board 100 instead of the power supply board 500.

[0044] The external information terminal board 600 outputs an external information signal (outer end signal) to the outside of the gaming machine PM based on the gaming information signal from the main control board 100. The external information signals output by the external information terminal board 600 as external information to external devices outside the machine include, for example, jackpot signals, continuous winning signals, symbol determination signals, prize ball signals (also referred to as prize ball information signals), door frame opening signals, security signals (also referred to as security information signals), magnetic sensor abnormality signals, disconnection short-circuit power supply abnormality signals, abnormal sensor detection (such as abnormal ball entry passing time) signals, and the like. In addition, external devices installed outside the gaming machine PM include a data display and a hall computer. The data display is a device installed on the upper part of the gaming machine PM and displays data (gaming information) related to the operating state of the gaming machine PM based on the external information signal output from the gaming machine PM. The gaming information displayed on this data display becomes a useful reference material for the player to select a gaming machine. The hall computer is a device that aggregates the operating states of each gaming machine (including this gaming machine PM) based on the external information signals output from each gaming machine installed in the hall of the gaming parlor and manages the operating status of each gaming machine. This hall computer may be electrically connected to this gaming machine PM via the data display or may be electrically connected to this gaming machine PM without passing through the data display.

[0045] <Basic Operations of Pachinko Machine> The pachinko gaming machine PM configured as described above has an outer frame 1 fixedly installed on the gaming island of the gaming facility. With the front frame 2, the glass frame 5, etc. in a closed and locked state, it is used for gaming. The game starts by storing game balls in the upper ball tray 8 and rotating the firing handle 12. When the firing handle 12 is rotated, the game balls stored in the upper ball tray 8 are sent one by one to the firing mechanism 14 by the ball feeding mechanism 13 disposed on the back side of the glass frame 5, and are launched into the game area PA by the firing mechanism 14. At this time, when the firing handle 12 is operated by less than a predetermined amount, the game balls do not reach the right area PA2 and flow down the left area PA1. In this left area PA1, a left flow path is formed to direct the game balls to the first start port 51 or the general winning ports 61 to 63. On the other hand, when the firing handle 12 is operated by a predetermined amount or more, the game balls reach the right area PA2 and flow down the right area PA2. In this right area PA2, a right flow path is formed to direct the game balls to the operating gate 53, the general winning port 64, the second start port 52, and the big winning port 54. The game balls flowing down the left area PA1 or the right area PA2 can enter any one of the first start port 51, the second start port 52, the operating gate 53, the big winning port 54, and the general winning ports 61 to 64 according to the path assigned in these left area PA1 or right area PA1. If they do not enter any of the winning ports, they flow down to the out port 29.

[0046] When a game ball flowing down the game area PA enters any of the first start port 51, the second start port 52, the big winning port 54, or the general winning ports 61 to 63, prize balls corresponding to the type of the winning port are paid out by the prize ball payout unit 34 to the upper ball tray 8 or the lower ball tray 9. In the present embodiment, as the number of prize balls paid out when one game ball enters each winning port (referred to as "unit prize ball number"), the first start port 51 is set to "4", the second start port 52 is set to "1", the general winning ports 61 to 64 are set to "3", and the big winning port 54 is set to "15". Note that the unit prize ball numbers of the respective winning ports are not limited to the numbers exemplified in the present embodiment, and other unit prize ball numbers may be applied. For example, as the unit prize ball number, the first start port 51 may be set to "1" instead of "4". Also, the second start port 52 may be set to "3" instead of "1". Further, the general winning ports 61 to 64 may be set to "5" instead of "3". Also, the big winning port may be set to "10" instead of "15".

[0047] When a game ball enters the first start port 51 or the second start port 52, a lottery random number value for a special symbol is acquired and temporarily stored as a special symbol operation hold ball up to a predetermined upper limit number. Then, when a predetermined start condition (the special symbol variation start condition described later) is satisfied, a winning / losing determination, a symbol determination, and a variation pattern determination are performed on the lottery random number value related to the earliest operation hold ball, and in a manner corresponding to this determination result, the special symbol is variably displayed on the first special symbol display device 71 or the second special symbol display device 72, and the decorative symbol is variably displayed on the effect display device 70. The variable display of the special symbol and the decorative symbol stops synchronously after the elapse of a variable time corresponding to the selected variation pattern.

[0048] When the first special symbol or the second special symbol is fixedly displayed in a stop mode indicating a big win, the game shifts to a special game (big win game) that is more advantageous for the player than the normal game. In each round game (unit game) of this big win game, an opening / closing operation is performed to change the big winning opening 54 to the open state one or more times. When a specified number of game balls enter the big winning opening 54 or when the opening time of the big winning opening 54 reaches the opening limit time, the ongoing round game ends. Here, the stop mode of the decorative symbol indicating a big win is, for example, a mode in which the types of three symbols match. In the present embodiment, when the special symbol and the decorative symbol are fixedly displayed in a stop mode indicating a big win, a plurality of round games (unit games) are executed as the big win game.

[0049] In the present embodiment, when winning a predetermined big win, the probability variation function of the special symbol may operate from after the end of the big win game until the number of variation times of the special symbol reaches a predetermined final number of times. When the probability variation function of the special symbol operates, since the big win probability of the special symbol lottery shifts from the normal low probability state to the high probability state, a new big win (big win game) is likely to occur relatively early. Note that the probability variation function of the special symbol may continue until the next big win occurs. Also, as the above-mentioned predetermined final number of times, "10,000 times" corresponding to the number of variation display times until the next big win occurs substantially may be set.

[0050] Also, after the big win game ends, the variation time shortening function of the special symbol may operate either accompanying the probability variation function of the special symbol or independently. When the variation time shortening function of the special symbol operates, the average variation time of the special symbol and the decorative symbol tends to be shortened compared to normal, and the number of special symbol lotteries per unit time improves (the ease of obtaining a big win per unit time can be enhanced).

[0051] Furthermore, after the jackpot game ends, the electric-chute support function (also simply referred to as "electric support") may operate either in association with or independently of the special symbol variation time reduction function. The electric-chute support function is a state (also referred to as the "electric support state" or the "easy ball entry state") in which the ease of ball entry into the second start port 52 is enhanced by the operation of the normal symbol probability variation function, the normal symbol variation time reduction function, and the release extension function of the normal electric accessory 522. When the normal symbol probability variation function operates, the winning probability of the normal symbol becomes higher than in the normal state. When the normal symbol variation time reduction function operates, the variation time of the normal symbol is shortened. When the release extension function of the normal electric accessory 522 operates, the release time of the normal electric accessory 522 is extended compared to the normal state. In this easy ball entry state, the number of variations of the normal symbol per unit time is likely to increase more than usual, and the ease of ball entry into the second start port 52 is also enhanced. Therefore, the possibility of an increase in the number of balls entering the second start port 52 also improves. Thus, when the electric-chute support function operates, the opportunity to obtain bonus balls due to balls entering the second start port 52 during that period increases, and as a result, it becomes possible to continue the game with little reduction in the number of held balls. That is, the "base," which is the ratio of the number of bonus balls to the number of balls launched, increases. Hereinafter, the state in which the electric-chute support function is operating is also referred to as the "high base state," and the state in which the electric-chute support function is not operating is also referred to as the "low base state."

[0052] <Main functional configurations of the pachinko gaming machine> Next, with additional reference to FIG. 4, various functions of the pachinko gaming machine PM (mainly the main control board 100 / effect control board 200) according to the present embodiment will be described. Note that FIG. 4 is a functional block diagram of the present gaming machine PM (mainly the main control board 100 / effect control board 200).

[0053] As shown in FIG. 4, the main control board 100 includes a ball entry determination means 110, a game lottery random number generation means 120, a hold control means 130, a preliminary determination means 135, a special symbol lottery processing means 140, a normal symbol lottery processing means 145, a special game control means 150, a symbol display control means 155, an electric accessory control means 160, a game state control means 165, an error monitoring control means 170, a main information storage means 180, and a command transmission / reception means 190. Each of the above means in the main control board 100 functionally represents a configuration composed of hardware such as a main CPU 101, a ROM 102, a RAM 103, and an electronic circuit provided on the main control board 100, and software such as a control program stored in the ROM 102, etc.

[0054] Based on detection signals from the first start port switch 511, the second start port switch 521, the operating gate switch 531, the big winning port switch 541, the general winning port switches 611 and 641, etc., the ball entry determination means 110 determines the entry of game balls into each winning port. When the ball entry determination means 110 detects the entry of a game ball at the first start port switch 511, it generates an effect control command indicating that fact (referred to as the "first start port winning command"), and when it detects the entry of a game ball at the second start port switch 521, it generates an effect control command indicating that fact (referred to as the "second start port winning command"). When it detects the passage of a game ball at the operating gate switch 531, it generates an effect control command indicating that fact (referred to as the "operating gate winning command"). When it detects the entry of a game ball at the big winning port switch 541, it generates an effect control command indicating that fact (referred to as the "big winning port winning command"). When it detects the entry of a game ball at the left general winning port switch 611, it generates an effect control command indicating that fact (referred to as the "left general winning port winning command"). When it detects the entry of a game ball at the right general winning port switch 611, it generates an effect control command indicating that fact (referred to as the "right general winning port winning command"), and temporarily stores this in the command storage area of the main information storage means 180.

[0055] The game lottery random number generation means 120 captures the built-in random number generated by the random number generation circuit of the main control microcomputer 110 in software, and adds the software random number per special symbol described later to generate the random number per special symbol used for the winning / losing lottery of the special symbol. In addition, the game lottery random number generation means 120 includes a random number counter for generating various software random numbers by the program processing of the main CPU 101. These random number counters serve as random number generation means for generating random numbers in software. As these software random numbers, there are the software random number per special symbol added to the aforementioned built-in random number for winning number generation, the software initial value random number per special symbol for determining the initial value for new updates after one cycle of update of the software random number per special symbol, the special symbol stop symbol random number used for determining the winning symbol (combination of symbols that activates the condition device) as the stop symbol of the special symbol, the special symbol stop symbol initial value random number for determining the initial value for new updates after one cycle of update of the special symbol stop symbol random number, the special symbol variation pattern random number used for selecting the variation pattern of the special symbol, the random number per normal symbol used for the winning / losing lottery of the normal symbol, the initial value random number per normal symbol for determining the initial value for new updates after one cycle of update of the random number per normal symbol, the normal symbol variation pattern random number used for selecting the variation pattern of the normal symbol, and the like. As for the update timing of these software random numbers, they are updated once (increment, decrement, addition of prime numbers, etc.) every time a timer interrupt process occurs, and for the initial value random numbers, they are updated using the remaining time of the interrupt cycle even while the timer interrupt process is not being executed (during loop processing).

[0056] The hold control means 130 includes a special symbol hold control means 131 and a normal symbol hold control means 132.

[0057] The special symbol hold control means 131 obtains a random number value per special symbol, a symbol random number value per special symbol, and a variation pattern random number value per special symbol, which are lottery random number values related to the special symbol game, upon the entry of a game ball into the first start port 51 or the second start port 52, and manages the random number values as operation hold ball information for the first special symbol or the second special symbol. The special symbol hold control means 131 temporarily stores the operation hold ball information for the first special symbol or the second special symbol, respectively, up to a predetermined upper limit number (4) in the first special symbol hold storage area or the second special symbol hold storage area of the main information storage means 180 in a form combined with the entry order of the hold balls.

[0058] In the first special symbol hold storage area and the second special symbol hold storage area, a hold 1 storage area (the first hold storage area), a hold 2 storage area (the second hold storage area), a hold 3 storage area (the third hold storage area), and a hold 4 storage area (the fourth hold storage area) are respectively provided in the order of the entry of balls into the start ports 51 and 52. Each hold storage area can store a set of a random number per special symbol, a symbol random number per special symbol, and a variation pattern random number per special symbol as operation hold ball information. The operation hold ball information is stored in the order of the hold 1 storage area, the hold 2 storage area, the hold 3 storage area, and the hold 4 storage area, while being consumed in the order of the hold 1 storage area, the hold 2 storage area, the hold 3 storage area, and the hold 4 storage area (the principle of first in, first out). Also, when the hold ball information in the hold 1 storage area is consumed, the hold ball information stored in the hold 2 storage area, the hold 3 storage area, and the hold 4 storage area is respectively shifted to the storage areas with lower numbers, and the content of the hold 4 storage area is cleared to zero.

[0059] Furthermore, the special symbol hold control means 131 has a first special symbol hold ball number counter for counting the number of operation hold balls of the first special symbol and a second special symbol hold ball number counter for counting the number of operation hold balls of the second special symbol. As an update process for the number of operation hold balls of the special symbol, the special symbol hold control means 131 adds 1 to the corresponding counter each time one operation hold ball of the special symbol is obtained, and subtracts 1 from the corresponding counter each time one operation hold ball is consumed.

[0060] In addition, when the special symbol holding control means 131 updates (adds or subtracts) the number of held balls in the first special symbol or the second special symbol, it generates an effect control command (referred to as a "symbol storage number command") including the update information of the number of held balls, and temporarily stores this in the command storage area of the main information storage means 180. This single command includes information on both the number of held balls in the first special symbol and the number of held balls in the second special symbol. In principle, the held balls of each special symbol are consumed in the order in which they enter the ball. However, in this embodiment, so-called preferential digestion is adopted, in which the variable display of the second special symbol is preferentially executed over the first special symbol. Therefore, while there are held balls related to the second special symbol game, regardless of the existence of held balls related to the first special symbol game, the held balls related to the second special symbol game are preferentially digested. Under this preferential digestion, when there are held balls in the second special symbol, the digestion of the held balls in the first special symbol will be postponed even if there are held balls in the first special symbol.

[0061] When a game ball enters the operating gate 53, the normal symbol holding control means 132 acquires the random number values for the normal symbol game, namely, the random number value per normal symbol, the symbol random number value per normal symbol, and the variable pattern random number value per normal symbol, which are lottery random number values related to the normal symbol game, and manages these random number values as the held ball information of the normal symbol. The normal symbol holding control means 132 temporarily stores the held ball information of the normal symbol in the normal symbol holding storage area of the main information storage means 180 in a form combined with the order of entry of the held balls up to a predetermined upper limit number (4). In addition, the normal symbol holding control means 132 has a normal symbol held ball number counter for counting the number of held balls in the normal symbol. As an update process for the number of held balls in the operating normal symbol, the normal symbol holding control means 132 adds 1 to the corresponding counter each time it acquires one held ball in the normal symbol, and subtracts 1 from the corresponding counter each time one held ball is digested.

[0062] When the pre-determination means 135 acquires a retained ball in operation of a special symbol at a predetermined pre-determination timing, it executes a pre-determination for a preview notice for the retained ball in operation. As an example of the above pre-determination timing, (1) when a retained ball in operation of a first special symbol is acquired during waiting for a win and the electric chewing support function is not in operation, (2) when a retained ball in operation of a second special symbol is acquired during waiting for a win and the electric chewing support function is in operation, (3) when a retained ball in operation of a second special symbol is acquired during a big win or a small win. It is when any one of these conditions is satisfied. Note that the above pre-determination timing is an example, and the pre-determination timing can be changed according to the specifications of the gaming machine (for example, in a model that has a start port related to a second special symbol without a normal electric accessory and can store 8 retained balls during normal times, the above (1) is applied not only to the first special symbol but also to the second special symbol), or a specification that does not provide a pre-determination timing and performs pre-determination at any time may be adopted. Also, in each gaming state, only the retained ball in operation of the special symbol of the main party of the game may be the target of pre-determination. For example, in the normal gaming state, only the retained ball in operation of the first special symbol is the target of pre-determination, and in the time-saving gaming state, the latent probability variation gaming state, and the probability variation gaming state, it is preferable that only the retained ball in operation of the second special symbol is the target of pre-determination. Specifically, the pre-determination means 135 reads out the random number value corresponding to the retained ball in operation acquired this time from the first special symbol retained storage area or the second special symbol retained storage area of the main information storage means 180, and sequentially executes a pass / fail pre-determination (pass / fail pre-determination), a symbol pre-determination (symbol pre-determination), and a variation pattern pre-determination (variation pattern pre-determination). Although the pre-determination tables used in each pre-determination are not shown in the figure, each of the pass / fail pre-determination table, the symbol pre-determination table, and the variation pattern pre-determination table has an area corresponding to the total number of random numbers divided into a plurality of areas, and a lottery ID (a number indicating the result of the pre-determination (also referred to as the "pre-determination number")) is assigned to each of these areas (determination setting numbers). Therefore, the result of this pre-determination conforms to the result of the main lottery (the result of the pass / fail determination, the result of the symbol determination, and the result of the variation pattern determination) by the special symbol lottery processing means 140 described later.Incidentally, the success / failure pre-judgment table, the symbol pre-judgment table, etc. may be the same as the success / failure lottery table, the symbol lottery table, etc. used in the lottery when the actual variation starts. Here, since the variation pattern pre-judgment table may change in the game situation at the start of variation (such as the presence or absence of certain probability variation, time shortening, whether it is during the limited frequency period for referring to the special table, the number of reserved balls, etc.), as described above, it is desirable to determine in which of the plurality of regions it is included. Also, as a modification, it may be configured to pre-judge the random number value such as a register on the main CPU 101 that is temporarily stored before being stored in the above-described first special symbol reservation storage area or the second special symbol reservation storage area. Then, the pre-judgment means 135 sequentially generates an effect control command (referred to as a "pre-judgment command") including information on the result of the pre-judgment (pre-judgment number), and stores this in the command storage area of the main information storage means 180.

[0063] The special symbol lottery processing means 140 includes the special symbol win / loss determination means 141, the special symbol stop symbol determination means 412, and the special symbol variation pattern determination means 143. When the variation start condition for the first special symbol or the second special symbol is satisfied, the special symbol lottery processing means 140 reads out the random number value per special symbol, the symbol random number value per special symbol, and the random number value for the special symbol variation pattern stored in the earliest storage area (hold 1 storage area) of the special symbol hold storage area in the main information storage means 180, and stores them in the special symbol win / loss determination area, the special symbol symbol determination area, and the special symbol variation pattern determination area of the main information storage means 180, respectively. Here, "the variation start condition for the first special symbol is satisfied" means that all of the following conditions are met: (A1) not in the middle of a big win, (A2) the first special symbol and the second special symbol are in the variation standby state, and (A3) there is an operation hold ball for the first special symbol. Also, "the variation start condition for the second special symbol is satisfied" means that all of the following conditions are met: (B1) not in the middle of a big win, (B2) the first special symbol and the second special symbol are in the variation standby state, and (B3) there is an operation hold ball for the second special symbol. When the variation start conditions for the first special symbol and the second special symbol are satisfied simultaneously, the variation start condition for the second special symbol is preferentially processed under the above-mentioned preferential digestion.

[0064] The special symbol win / loss determination means 141 reads out the random number value per special symbol from the special symbol win / loss determination area of the main information storage means 180 and executes a win / loss determination to determine which of a big win, a small win, or a loss the determination result corresponds to. The result of this win / loss determination is temporarily stored in the special symbol determination flag of the main information storage means 180 (for example, big win data "55H", small win data "33H", loss data "00H") and cleared when the variation of the special symbol stops after being used in subsequent processing. The special symbol win / loss determination means 141 holds a special symbol win / loss lottery table referred to during this win / loss determination.

[0065] Here, FIG. 5 is a diagram schematically showing a special symbol winning / losing lottery table. FIG. 5(A) is referred to in a game state where the probability variation function of the special symbol is not activated (low probability state), and FIG. 5(B) is referred to in a game state where the probability variation function of the special symbol is activated (high probability state). In the special symbol winning / losing lottery table, a random number range of the random number value for a special symbol and a result of the winning / losing determination of the special symbol (big win, loss) are associated with each other. As shown in FIG. 5, in the winning / losing determination of the special symbol, in a game state where the probability variation function of the special symbol is not activated (low probability state), when the random number value for a special symbol falls within the range of "0 to 204", it is a big win, and in a game state where the probability variation function of the special symbol is activated (high probability state), when the random number value for a special symbol falls within the range of "0 to 1506", it is a big win. That is, when the probability variation function of the special symbol is activated, the winning probability of a big win varies from "1 / 319.69" with a low probability to "1 / 43.49" with a high probability. Thus, the winning probability of a big win changes according to the game state, but the winning probability of a big win is set to be equal in the winning / losing determination of the first special symbol and the winning / losing determination of the second special symbol. In addition, in this embodiment, "small win" is not set as a result of the winning / losing determination of the special symbol, but "small win" may be set as a result of the winning / losing determination of the special symbol. The winning probability of a small win is set to the same winning probability regardless of the game state (low probability state, high probability state).

[0066] The special symbol stop symbol determination means 142 determines the stop symbol of the first special symbol or the second special symbol based on the result of the winning / losing lottery of the first special symbol or the second special symbol. As shown in FIG. 6, the special symbol stop symbol determination means 142 has a first special symbol big win symbol table and a second special symbol big win symbol table that are referred to when determining the big win symbols (big win types) of the first special symbol and the second special symbol. In this embodiment, "specific big win" means a big win (probability variation big win) that triggers the activation of the probability variation function of the special symbol after the end of the big win game, and "normal big win" means a big win (non-probability variation big win) that does not trigger the activation of the probability variation function of the special symbol after the end of the big win game.

[0067] In this embodiment, as multiple types of gaming states, a normal gaming state, a time-saving gaming state, and a probability variation gaming state are set. As types of the gaming states, (1) a gaming state in which the probability variation function of special symbols, the shortening function of the variation time of special symbols, and the electric-chute support function are activated is called the "probability variation state" or the "probability variation gaming state", (2) a gaming state in which the probability variation function of special symbols does not activate while the shortening function of the variation time of special symbols and the electric-chute support function are activated is called the "time-saving state" or the "time-saving gaming state", and (3) a state in which all functions are not activated is called the "normal state" or the "normal gaming state". Here, it can be said that the "probability variation gaming state" and the "time-saving gaming state" are gaming states that are advantageous to the player compared to the "normal gaming state". Therefore, hereinafter, the probability variation gaming state and the time-saving gaming state are also referred to as "advantageous gaming states", which are gaming states with a higher degree of advantage to the player than the normal gaming state.

[0068] Note that each gaming state can be expressed as a combination of the operating state of the special symbol probability variation function (high probability state / low probability state) and the operating state of the electric chu support function (high base state / low base state): (1) the probability variation gaming state as the "high probability high base state", (2) the time shortening gaming state as the "low probability high base state", and (3) the normal gaming state as the "low probability low base state". In addition, there may be a gaming state in which the operating state of the probability variation function is the high probability state while the operating state of the electric chu support function is the low base state (one of the gaming states advantageous to the player compared to the "normal gaming state"), and such a gaming state is referred to as the potential probability gaming state, and this potential probability gaming state may be expressed as the "high probability low base state". This potential probability gaming state ("high probability low base state") is a suitable gaming state for conducting a game mainly based on small wins, and the details will be described later. Regarding these states (combinations of low probability / high probability and low base / high base), unless otherwise specified, it refers to the gaming state in a state other than during a big win or a small win (a state where win / loss determination and variable display are possible). During a big win, it is the low probability low base state, and during a small win, it is the same gaming state as the gaming state at the time of small win selection. At this time, the special symbol variation time shortening function means that, among the first special symbol and the second special symbol, at least the variation time of the special symbol that is the main body of the game in that gaming state is shortened. That is, in the present embodiment, when the special symbol variation time shortening function is activated, in the gaming state where the variation display of the first special symbol is the main body of the game (normal gaming state), at least the variation time (average variation time) of the first special symbol is shortened, and in the gaming state where the variation display of the second special symbol is the main body of the game (probability variation gaming state, potential probability gaming state, time shortening gaming state), at least the variation time (average variation time) of the second special symbol is shortened.

[0069] In this embodiment, when the result of the winning or losing determination of the special symbol is a big win, the game state after the end of the big win game is determined according to (1) the big win type (the type of symbol group) and (2) the game state at the time of winning the big win. Note that the number of continuous times of each game state (the number of times of the variable display of the special symbol) is the number of times the probability variation function of the special symbol operates (referred to as the "probability variation number of times"), the number of times the variable time shortening function of the special symbol operates (referred to as the "variable time shortening number of times"), and the number of times the electric cheat support function operates (referred to as the "electric support number of times"). In this embodiment, since the variable time shortening function and the electric cheat support function of the special symbol start operating simultaneously and end operating simultaneously, the "variable time shortening number of times" and the "electric support number of times" are the same number of times (therefore, in FIG. 6, the "variable time shortening number of times" and the "electric support operation number of times" are described in the same column).

[0070] FIG. 6(A) is a diagram schematically showing the first special symbol big win symbol table. In this first special symbol big win symbol table, for the special symbol winning symbol random number value, the symbol group, the big win type, the probability variation number of times, the variable time shortening number of times (electric support number of times), the specified number of rounds of the big win game, and the opening time (maximum opening time) of the big winning opening 54 in each round are respectively associated (in this example, for the sake of convenience, the description of the stop symbol is omitted). In the first special symbol big win table, two types of big win types are set corresponding to each symbol group. Specifically, as the two types of big win types (symbol groups), it is classified into a 4R specific big win (symbol group A) and a 4R normal big win (symbol group B).

[0071] (4R Specific Big Win: Symbol Group A) When winning the "4R specific jackpot (symbol group A)" of the first special symbol, the number of probability fluctuations is set to "10,000 times", the number of times of shortening the fluctuation time is set to "10,000 times", and the number of times of electric support is set to "10,000 times", and a probability-variable game state is set as the game state after the end of the jackpot game. This probability-variable game state has an extremely large number of "10,000 times" set as its continuation times (the number of probability fluctuations, the number of times of shortening the fluctuation time, the number of times of electric support). Since it is probabilistically impossible (winning with a probability of about 1 / 44) not to win the jackpot until reaching this continuation times, it actually continues until the next jackpot occurs. Also, when winning the "4R specific jackpot (symbol group A)" of the first special symbol, the specified number of rounds of the jackpot game is "4 rounds", and the maximum opening time of the big winning opening 54 in one round of the round game is "29 seconds".

[0072] (4R normal jackpot: symbol group B) When winning the "4R normal jackpot (symbol group B)" of the first special symbol, the number of probability fluctuations is set to "0 times", the number of times of shortening the fluctuation time is set to "100 times", and the number of times of electric support is set to "100 times", and a time-shortening game state is set as the game state after the end of the jackpot game. This time-shortening game state continues until the number of variable displays of the special symbol reaches 100 times, or until the next jackpot occurs within these 100 times. When the time-shortening game state ends because the number of variable displays of the special symbol reaches 100 times, it shifts to the normal game state from the next variable display of the special symbol. Also, when winning the "4R normal jackpot (symbol group B)" of the first special symbol, the specified number of rounds of the jackpot game is "4 rounds", and the maximum opening time of the big winning opening 54 in one round of the round game is "29 seconds".

[0073] Fig. 6(B) is a diagram schematically showing the second special symbol jackpot symbol table. In this second special symbol jackpot symbol table, for each special symbol jackpot symbol random value, a symbol group, a jackpot type, the number of probability fluctuations, the number of times of shortening the fluctuation time (the number of times of electric support), the specified number of rounds of the jackpot game, and the opening time (maximum opening time) of the big winning opening 54 in each round are respectively associated (in this example, for the sake of convenience, the description of the stopped symbols is omitted). In the second special symbol jackpot table, three types of jackpot types are set corresponding to each symbol group. Specifically, as the three types of jackpot types (symbol groups), they are classified into the 16R specific jackpot (symbol group C), the 4R specific jackpot (symbol group D), and the 4R normal jackpot (symbol group E).

[0074] (16R Specific Jackpot: Symbol Group C) When winning the "16R specific jackpot (symbol group C)" of the second special symbol, the number of probability fluctuations "10,000 times", the number of times of shortening the fluctuation time "10,000 times", and the number of times of electric support "10,000 times" are set, and the probability variable game state is set as the game state after the end of the jackpot game. As described above, this probability variable game state is set with an enormous number of "10,000 times" as its continuous number of times, and continues substantially until the next jackpot occurs. Also, when winning the "16R specific jackpot (symbol group C)" of the second special symbol, the specified number of rounds of the jackpot game is "4 rounds", and the maximum opening time of the big winning opening 54 in one round of the round game is "29 seconds". Also, this 16R specific jackpot may also be set to be winnable in the first special symbol. In that case, it is preferable to set it to be less likely to win than the second special symbol (for example, 5% of all jackpot symbols, and in the first special symbol, the 16R specific jackpot is 5%, the 4R specific jackpot is 60%, and the 4R normal jackpot is 35%).

[0075] (4R Specific Jackpot: Symbol Group D) When winning the "4R Specific Jackpot (Symbol Group D)" of the second special symbol, the number of probability fluctuations is set to "10,000 times", the number of times of shortening the fluctuation time is set to "10,000 times", and the number of times of electric support is set to "10,000 times". After the jackpot game ends, a probability-variable game state is set as the game state. As described above, this probability-variable game state has an extremely large number of "10,000 times" set as its continuous number, and it continues substantially until the next jackpot occurs. Also, when winning the "4R Specific Jackpot (Symbol Group D)" of the second special symbol, the specified number of rounds of the jackpot game is "4 rounds", and the maximum opening time of the big winning opening 54 in one round of the round game is "29 seconds".

[0076] (4R Normal Jackpot: Symbol Group E) When winning the "4R Normal Jackpot (Symbol Group E)" of the second special symbol, the number of probability fluctuations is set to "0 times", the number of times of shortening the fluctuation time is set to "100 times", and the number of times of electric support is set to "100 times". After the jackpot game ends, a time-shortening game state is set as the game state. This time-shortening game state continues until the number of variable displays of the special symbol reaches 100 times, or until the next jackpot occurs within these 100 times. When the time-shortening game state ends because the number of variable displays of the special symbol reaches 100 times, the game state changes to the normal game state from the next variable display of the special symbol. Also, when winning the "4R Normal Jackpot (Symbol Group E)" of the second special symbol, the specified number of rounds of the jackpot game is "4 rounds", and the maximum opening time of the big winning opening 54 in one round of the round game is "29 seconds".

[0077] Here, in the present embodiment, as the jackpot types, there are three types: 16R specific jackpot (symbol group C), 4R specific jackpot (symbol groups A and D), and 4R normal jackpot (symbol groups B and E). And the expected value of winning prize balls in the special game (referred to as "expected value of winning prize balls") is 16R specific jackpot > 4R specific jackpot = 4R normal jackpot. Here, the actual number of rounds of the special game when winning the jackpot with the first special symbol is "4 rounds", while the actual number of rounds of the special game when winning the jackpot with the second special symbol is "16 rounds". Therefore, compared with the case where the jackpot occurs with the first special symbol, when the jackpot occurs with the second special symbol, there is a higher possibility of transitioning to a special game with a larger number of rounds, and it is advantageous for the player in terms of being able to obtain a large number of game balls. The actual number of rounds of this special game corresponds to the number of executions of the "long open-round game" set for that special game. In the present embodiment, the maximum open time for each round of the jackpot game is set to a fixed time of 29 seconds (all rounds are "long open-round games"), but in a predetermined round or all rounds during the same jackpot game, a "short open-round game" is provided in which the maximum open time of the big winning opening 54 is shortened to 2 seconds. Thus, even if the number of rounds of the jackpot game is the same, a configuration having jackpots with different actual numbers of rounds of being able to obtain game balls substantially (jackpots with different actual numbers of rounds) may be adopted. The long open-round game is a round game in which the open time (maximum open time) of the big winning opening 54 is set such that it is possible or easy to enter the game balls with the specified count number (full count = 10 balls) into the big winning opening 54. The short open-round game is a round game in which the open time (maximum open time) of the big winning opening 54 is set such that it is impossible or difficult to enter the game balls with the specified count number (full count = 10 balls) into the big winning opening 54.

[0078] The special symbol variation pattern determination means 143 determines the variation pattern of the special symbol based on the special symbol variation pattern random number value. Here, the special symbol variation pattern determination means 143 holds a plurality of types of variation pattern tables that are referred to when selecting the variation pattern of the special symbol. The special symbol variation pattern determination means 143 selects one of the plurality of types of variation pattern tables based on the current variation pattern selection state. The relationship between the variation pattern selection state and the variation pattern table will be described later. Each variation pattern table defines a plurality of types of variation patterns. In each figure, for convenience of explanation, "selection rate" is shown, but actually, a determination value (range of random number values) for determining the variation pattern is set according to the special symbol variation pattern random number value, and the variation pattern is determined based on which determination value the variation pattern random number value belongs to. Each type of variation pattern has a variation time associated with it as an end condition for the variation display of the special symbol, and it is assumed that the variation display of the decorative symbol is also executed at that variation time.

[0079] Here, the variation pattern selection state will be described. The variation pattern selection state is one of the selection conditions referred to when selecting the variation pattern (variation pattern table). In this example, as a plurality of types of variation pattern selection states, "normal selection state", "time-saving selection state", and "probability variation selection state" are set. The normal selection state is a variation pattern selection state set corresponding to a game state (normal game state) in which none of the probability variation function, variation time shortening function, and electric chewing support function of the special symbol are operating. The time-saving selection state is a variation pattern selection state set corresponding to a game state (time-saving game state) in which the probability variation function of the special symbol is not operating, but the variation time shortening function and the electric chewing support function of the special symbol are operating. The probability variation selection state is a variation pattern selection state set corresponding to a game state (probability variation game state) in which all of the probability variation function, variation time shortening function, and electric chewing support function of the special symbol are operating.

[0080] As shown in FIGS. 7 to 9, the special symbol variation pattern table has different columns for the first special symbol and the second special symbol. Even if the same special symbol variation pattern random number value is obtained, different variation patterns can be selected. Here, the number of balls in operation on hold ( "0 balls on hold", "1 to 2 balls on hold", "3 balls on hold") described in each figure means the number of balls in operation on hold for the first special symbol in the case of the first special symbol variation pattern lottery (the number of balls in operation on hold after hold digestion), and means the number of balls in operation on hold for the second special symbol in the case of the second special symbol variation pattern lottery (the number of balls in operation on hold after hold digestion). The number of balls in operation on hold is the number of balls in operation on hold existing at the time of lottery of the variation pattern (at the start of the variation display / after hold digestion) (excluding the balls in operation on hold digested by the variation display). As a modification, the total value of the number of balls in operation on hold for the first special symbol and the second special symbol may be used.

[0081] The decorative symbol variation performance carried out in conjunction with the variation display of the special symbol is determined based on the type (variation time) of the variation pattern of the special symbol. FIGS. 7 to 9 also describe, for reference, the content of the variation performance set corresponding to each variation pattern (variation time). In the figures, "ultra-shortened variation", "shortened variation", and "normal variation" are performances in which three columns of decorative symbols vary and "lose" in a so-called scattered state without passing through a reach state even once. Hereinafter, the ultra-shortened variation, the shortened variation, and the normal variation are collectively referred to as "non-reach loss". The non-reach loss types differ from each other in the variation mode in that the variation display stops in a shorter time for the shortened variation than the normal variation and for the ultra-shortened variation than the shortened variation.

[0082] "N-Reach (Normal Reach)" is a performance in which when the same decorative symbol stops in two of the three columns of decorative symbols (generally the left column and the right column) (reach state) and a different decorative symbol stops in the remaining one column (generally the middle column), it "loses", and when the same decorative symbol stops in the remaining one column (generally the middle column), it "hits the jackpot".

[0083] "SP Reach (Super Reach)" is a reach effect with a relatively higher expectation of a big win compared to the above N Reach. After the reach is established, it develops from the N Reach and is an effect where still images or videos such as anime or live-action are displayed. In this embodiment, as types of SP Reach, a plurality of types of SP Reach A to C are prepared. SP Reach A is a reach effect executed when the currently executing game state is the normal state. SP Reach B is a reach effect executed when the currently executing game state is the time-saving game state. SP Reach C is a reach effect executed when the currently executing game state is the probability-variable game state. In the variation pattern type of this embodiment, the expectation of a big win is set to increase in the order of "non-reach" < "N reach" < "SP reach". As a modification, the content of the SP reach effect may be the same (SP reach A) in the normal state and the time-saving game state, and a different SP reach (SP reach C) may be used when it is the probability-variable game state. Also, as another modification, a variation pattern including pseudo-continuity may be prepared. Pseudo-continuity is an effect (pseudo-continuous effect, pseudo-variation effect, pseudo-continuous variation effect, re-variation effect) that makes it appear as if a plurality of variation displays are performed by temporarily stopping (pseudo-stopping, once stopping) and re-varying the decorative pattern during a single variation display of the decorative pattern. That is, pseudo-continuity is an effect that executes a plurality of pseudo-variations in which all of the three columns of decorative patterns temporarily stop or definitely stop after starting to vary or re-vary. The greater the number of times of this pseudo-continuity (the number of pseudo-variations), the higher the possibility of developing into an SP reach with a high expectation of a big win.

[0084] (Variation Pattern Table 1) Figure 7 is a schematic diagram showing Variation Pattern Table 1. Variation Pattern Table 1 is a variation pattern table set when the currently staying variation pattern selection state is the normal selection state. The content of Variation Pattern Table 1 differs according to the result (big win, loss) of the determination of the special symbol.

[0085] In the deviation variable pattern table 1, variable patterns PH1-1 (shortened variation), PH1-2 (normal variation), PH1-3 (N reach), and PH1-4 (SP reach A) are set. Here, when the result of the winning or losing determination of the first special symbol is "deviation", any one of the variable patterns PH1-1 (shortened variation), PH1-2 (normal variation), PH1-3 (N reach), and PH1-4 (SP reach A) is selected. In the present embodiment, when the result of the winning or losing determination of the first special symbol is "deviation", the content of the reference table is set to be different according to the number of operation hold balls of the first special symbol (0 / 1 - 2 / 3). Even if the obtained special symbol variable pattern random number values are the same, different variable patterns can be selected. Specifically, the larger the number of operation hold balls of the first special symbol, the more likely a variable pattern with a relatively short variation time of the first special symbol is selected. The smaller the number of operation hold balls of the first special symbol, the more likely a variable pattern with a relatively long variation time of the first special symbol is selected. On the other hand, when the result of the winning or losing determination of the second special symbol is "deviation", regardless of the number of operation hold balls of the second special symbol (0 / 1 - 2 / 3), the variable pattern PH1-1 (shortened variation) or PH1-2 (normal variation) with a relatively short variation time is selected. As a modification, when the result of the winning or losing determination of the second special symbol is "deviation", regardless of the number of operation holds of the second special symbol, only the main variation pattern PH1-2 of the shortened variation is selected or the variable pattern PH1-2 of the shortened variation is most likely to be selected (it is preferable that the selection ratio is the same regardless of the number of operation hold balls of the second special symbol).

[0086] In the variable pattern table 1 for big wins, variable patterns PA1-1 (N reach) and PA1-2 (SP reach A) are set. Here, when the result of the winning or losing determination of the first special symbol is a big win, regardless of the big win type, the variable pattern PA1-1 (N reach) or PA1-2 (SP reach A) is selected. Similarly, when the result of the winning or losing determination of the second special symbol is a big win, regardless of the big win type, the variable pattern PA1-1 (N reach) or PA1-2 (SP reach A) is selected.

[0087] (Variable Pattern Table 2) FIG. 8 is a schematic diagram showing the Variable Pattern Table 2. The Variable Pattern Table 2 is a variable pattern table set when the current variable pattern selection state during stay is the time-saving selection state. The content of the Variable Pattern Table 2 varies according to the result (big win, loss) of the winning or losing determination of the special symbol.

[0088] In the Variable Pattern Table 2 for loss, Variable Patterns PH2-1 (ultra-shortened variation), PH2-2 (normal variation), PH2-3 (N reach), and PH2-4 (SP reach B) are set. Here, when the result of the winning or losing determination of the first special symbol is a loss, regardless of the number of non-operating reserved balls of the first special symbol (0 balls / 1 - 2 balls / 3 balls), any one of Variable Patterns PH2-2 (normal variation), PH2-3 (N reach), and PH2-4 (SP reach A) is selected. That is, when the result of the winning or losing determination of the first special symbol is a loss, the Variable Pattern PH2-1 (ultra-shortened variation) is never selected no matter how many non-operating reserved balls of the first special symbol there are. On the other hand, when the result of the winning or losing determination of the second special symbol is "loss", any one of Variable Patterns PH2-1 (ultra-shortened variation), PH2-2 (normal variation), PH2-3 (N reach), and PH2-4 (SP reach B) is selected. In this embodiment, when the result of the winning or losing determination of the second special symbol is "loss", the content of the reference table is set to vary according to the number of non-operating reserved balls of the second special symbol (0 balls / 1 - 2 balls / 3 balls). Even if the obtained special symbol variable pattern random number values are the same, different variable patterns can be selected. Specifically, when there are no non-operating reserved balls of the second special symbol, the Variable Pattern PH2-1 (ultra-shortened variation) is never selected. When there are non-operating reserved balls of the second special symbol, the larger the number of non-operating reserved balls of the second special symbol, the more likely the Variable Pattern PH2-1 (ultra-shortened variation) is to be selected.

[0089] In the variable pattern table 2 for big wins, variable patterns PA2-1 (N reach) and PA2-2 (SP reach B) are set. Here, when the result of the winning or losing determination of the first special symbol is a big win, regardless of the big win type, variable pattern PA2-1 (N reach) or PA2-2 (SP reach B) is selected. Similarly, when the result of the winning or losing determination of the second special symbol is a big win, regardless of the big win type, variable pattern PA2-1 (N reach) or PA2-2 (SP reach B) is selected.

[0090] (Variable Pattern Table 3) FIG. 9 is a schematic diagram showing the variable pattern table 3. The variable pattern table 3 is a variable pattern table set when the current staying variable pattern selection state is the probability variable selection state. The content of the variable pattern table 3 varies according to the result (big win or loss) of the winning or losing determination of the special symbol.

[0091] In the deviation variation pattern table 3, variation patterns PH3-1 (ultra-shortened variation), PH3-2 (normal variation), and PH3-3 (SP reach C) are set. Here, when the result of the winning or losing determination of the first special symbol is "deviation", regardless of the number of balls on hold for the operation of the first special symbol (0 balls / 1 - 2 balls / 3 balls), variation pattern PH3-2 (normal variation) or PH3-3 (SP reach C) is selected. That is, when the result of the winning or losing determination of the first special symbol is deviation, no matter how many balls on hold for the operation of the first special symbol there are, variation pattern PH3-1 (ultra-shortened variation) will not be selected. On the other hand, when the result of the winning or losing determination of the second special symbol is deviation, any one of variation patterns PH3-1 (ultra-shortened variation), PH3-2 (normal variation), and PH3-3 (SP reach C) is selected. At this time, when the result of the winning or losing determination of the second special symbol is deviation, the content of the reference table is set to be different according to the number of balls on hold for the operation of the second special symbol (specifically, according to the presence or absence of the balls on hold for the operation of the second special symbol). Even if the obtained special symbol variation pattern random number values are the same, different variation patterns can be selected. Specifically, when there are no balls on hold for the operation of the second special symbol, variation pattern PH3-1 (ultra-shortened variation) will not be selected, and variation pattern PH3-1 (ultra-shortened variation) can only be selected when there are balls on hold for the operation of the second special symbol. Therefore, compared with the case where there are no balls on hold for the operation of the second special symbol, when there are balls on hold for the operation of the second special symbol, there is a tendency for a variation pattern with a relatively shorter variation time to be more easily selected.

[0092] In the big win variation pattern table 3, variation pattern PA3-1 (SP reach C) is set. Here, when the result of the winning or losing determination of the first special symbol is a big win, regardless of the big win type (4R specific big win, 4R normal big win), variation pattern PA3-1 (SP reach C) is selected. Similarly, when the result of the winning or losing determination of the second special symbol is a big win, regardless of the big win type (16R specific big win, 4R specific big win, 4R normal big win), variation pattern PA3-1 (SP reach C) is selected.

[0093] As described above, in the variable pattern tables 1 to 3, the variation time of the special symbol is defined for each variation pattern. However, regardless of which variation pattern is selected, the fixed stop time (fixed display time) of the special symbol is set to "0.5 seconds". The fixed stop time (fixed display time) of the special symbol is the time when the special symbol is fixedly stopped and displayed (the time when the completely stopped state is maintained). In this embodiment, corresponding to the variation time and the fixed stop time of the special symbol, the variation time and the fixed stop time of the decorative symbol are also set. In the variable pattern tables 1 to 3, when a big win occurs, the production content and the variation time can be the same as when a loss occurs. However, it is preferable to make the final production content different between when a big win occurs and when a loss occurs. That is, even for the same N-reach, when a big win occurs, the decorative symbol becomes a triple (e.g., "7·7·7"), while when a loss occurs, the decorative symbol becomes a losing combination result (e.g., "7·8·7"). Also, even for the same SP reach A to C, when a big win occurs, the final production content becomes a production content indicating success, and the decorative symbol becomes a triple (e.g., the friendly character defeats the enemy character, and then "7·7·7" is displayed), while when a loss occurs, the final production content becomes a production content indicating failure, and the decorative symbol becomes a losing combination result (e.g., the friendly character is defeated by the enemy character, and then "7·8·7" is displayed). It is also preferable that when a big win occurs, compared to when a loss occurs, even if it is the same production content (when developing to the same SP reach), the variation time (production time) is longer. For example, for the SP reaches A to C when a big win occurs, it is preferable to set the variation time (production time) to be 10 seconds longer than the SP reaches A to C when a loss occurs.

[0094] After selecting the special symbol variation pattern, the special symbol variation pattern determination means 143 generates an effect control command (communication inspection command) for checking whether communication with the effect control board 200 is being performed normally in order to instruct the start of the variation of the decorative symbol to the effect control board 200, an effect control command (variation addition information designation command) including the special symbol variation addition pattern (information for adding or subtracting the variation time), an effect control command (variation pattern designation command) including the special symbol variation pattern information, an effect control command (symbol designation command) including the information of the character effect number (symbol group and game state), etc. (hereinafter, these commands are collectively referred to as "variation start commands"), and stores them in the command storage area of the main information storage means 180.

[0095] The normal symbol lottery processing means 145 includes a normal symbol winning determination means 146, a normal symbol stop symbol determination means 147, and a normal symbol variation pattern determination means 148. When the variation start condition of the normal symbol is satisfied, the normal symbol lottery processing means 145 reads out the normal symbol winning random value and the normal symbol variation pattern random value stored in the earliest storage area in the normal symbol hold storage area, and stores them in the normal symbol winning determination area and the normal symbol variation pattern determination area of the main information storage means 180, respectively. Here, the "variation start condition of the normal symbol" means (1) being in the state of waiting for the variation of the normal symbol, and (2) the presence of the operation hold balls of the normal symbol. When all of these conditions are satisfied, it is determined that the normal symbol is in a state where it can start to vary (a state where the variation start condition is established).

[0096] The normal symbol win / loss determination means 146 reads out a normal symbol winning random value from the normal symbol win / loss determination area of the main information storage means 180, executes the win / loss determination of the normal symbol, and determines whether the determination result corresponds to either "win" or "loss". The result of this win / loss determination of the normal symbol is temporarily stored in the normal symbol determination flag of the main information storage means 180, cleared when the normal symbol stops fluctuating after being used in subsequent processing. The normal symbol win / loss determination means 146 holds a normal symbol win / loss lottery table (not shown) that is referred to during this win / loss determination of the normal symbol. The winning probability of the normal symbol is set to "1 / 3001" when the electric chu support function (probability variation function of the normal symbol) is not operating, and set to "2999 / 3001" when the electric chu support function (probability variation function of the normal symbol) is operating.

[0097] The normal symbol stop symbol determination means 147 refers to a normal symbol stop symbol table (not shown), and when the result of the win / loss determination of the normal symbol is a win, selects a predetermined winning symbol (a stop symbol that triggers the operation of the normal electric accessory 522), while when the result of the win / loss determination of the normal symbol is a loss, selects a predetermined losing symbol (a stop symbol that does not trigger the operation of the normal electric accessory 522). In this embodiment, symbol A and symbol B are assigned as the winning symbols of the normal symbol, while symbol C is assigned as the losing symbol of the normal symbol.

[0098] The normal symbol variation pattern determination means 148 reads out the normal symbol variation pattern random value from the normal symbol variation pattern determination area of the main information storage means 180, and determines the variation pattern (variation time) of the normal symbol with reference to a normal symbol variation pattern table (not shown). The variation time of the normal symbol is set to "0.6 seconds" when the electric chute support function (the function for shortening the variation time of the normal symbol) is not operating, and is set to "0.2 seconds" when the electric chute support function (the function for shortening the variation time of the normal symbol) is operating. In any case where a normal symbol variation pattern is selected, the definite stop time (definite display time) of the normal symbol is set to "0.1 seconds". The definite stop time (definite display time) of the normal symbol is the time when the normal symbol is definitely stopped and displayed (the time when the completely stopped state is maintained). In the control of the normal symbol, in order to reduce the processing load of the main control board 100, when the electric chute support function is not operating, it is also conceivable to adopt a specification in which the hit probability of the normal symbol's validity determination is set to "0" and the variation time of the normal symbol is made a single one.

[0099] Also, the normal symbol lottery processing means 145 determines the opening pattern (opening time) of the normal electric accessory 522 according to the result of the validity determination of the normal symbol and the like. The normal symbol lottery processing means 145 holds a normal electric accessory opening pattern table that is referred to when determining the opening pattern (opening time) of the normal electric accessory 522. The opening pattern (opening time) of the normal electric accessory 522 is set to "0.2 seconds" when the electric chute support function (opening extension function) is not operating, and is set to "5.8 seconds" when the electric chute support function (opening extension function) is operating. Note that the opening pattern of the normal electric accessory 522 may be made different according to the type of winning symbol of the normal symbol. For example, as the opening pattern of the normal electric accessory 522, when the electric chute support function (opening extension function) is operating, if the winning symbol of the normal symbol is symbol A, it is set to "open for 3 seconds × 1 time → open for 2.8 seconds × 1 time (total opening time 5.8 seconds)", and if the winning symbol of the normal symbol is symbol B, it is set to "open for 2.8 seconds × 1 time → open for 3 seconds × 1 time (total opening time 5.8 seconds)".

[0100] When the result of the winning or losing determination of the special symbol is a big win, the special game control means 150 determines the execution time (demo time) of the big win start demo and the big win end demo and the execution time (round time) of the round game according to the determined big win type (symbol group). Then, the special game control means 150 generates an effect control command (referred to as the "big win start demo command") for instructing the execution of the big win start demo effect and an effect control command (referred to as the "big win end demo command") for instructing the execution of the big win end demo effect to the effect control board 200 side, and stores these in the command storage area of the main information storage means 180. Note that the big win start demo command also serves as an opportunity for the effect control board 200 side to determine the content of a series of in-big-win effects (big win start demo effect, round effect, big win end demo effect) developed during the big win game. Also, the special game control means 150 generates an effect control command (referred to as the "round effect designation command") for instructing the start of the round effect corresponding to each round game during the big win game, and stores this in the command storage area of the main information storage means 180. This round effect designation command includes information on the current round number and information on the opening and closing of the big winning opening 54. As will be described later with reference to FIG. 11, in this embodiment, the execution time of the big win start demo is uniformly set to 5 seconds and the execution time of the big win end demo is uniformly set to 20 seconds. However, regarding the execution time (demo time) of the big win start demo and the big win end demo, not only the big win type (symbol group) but also according to the game state at the time of big win selection, even for the same big win type (symbol group), the execution time (demo time) of the big win start demo and the big win end demo may be different.For example, on the premise that a 16R specific jackpot is selected even for the first special symbol, for the 4R normal jackpot, when hitting the jackpot in a low-probability low-base state, the execution time of the jackpot start demonstration is 5 seconds (as the jackpot start demonstration effect, execute effect A-1 displayed as "Normal Jackpot Start"), and the execution time of the jackpot end demonstration is 15 seconds (as the jackpot end demonstration effect, execute effect B-1 displayed as "Entering the Time-Saving Mode" and effect C for raising awareness about preventing forgetting the prepaid card (※ a storage medium storing information regarding the amount of money required to borrow game balls for gaming)). On the other hand, when hitting the jackpot in a high-probability high-base state or a low-probability high-base state, the execution time of the jackpot start demonstration is 5 seconds (as the jackpot start demonstration effect, execute effect A-1), and the execution time of the jackpot end demonstration is 10 seconds (as the jackpot end demonstration effect, execute effect B-1 and do not execute effect C). For the 16R specific jackpot and the 4R specific jackpot, when hitting the jackpot in a low-probability low-base state, the execution time of the jackpot start demonstration is 5 seconds (as the jackpot start demonstration effect, execute effect A-2 displayed as "Variable Probability Jackpot Start"), and the execution time of the jackpot end demonstration is 20 seconds (as the jackpot end demonstration effect, execute effect B-2 displayed as "Entering the Variable Probability Mode" and effect C). On the other hand, when hitting the jackpot in a high-probability high-base state or a low-probability high-base state, the execution time of the jackpot start demonstration is 5 seconds (as the jackpot start demonstration effect, execute effect A-2), and the execution time of the jackpot end demonstration may be 10 seconds (as the jackpot end demonstration effect, execute effect B-3 displayed as "Continuing the Variable Probability Mode" and do not execute effect C).In addition, on the premise that a 16R specific jackpot is also won in the first special symbol, if it is a jackpot in the first special symbol, regardless of the game state at the time of the jackpot, the execution time of the jackpot start demo is 5 seconds (5 seconds in any of the 16R specific jackpot, 4R specific jackpot, and 4R normal jackpot, and as the jackpot start demo performance, performance A-1 or performance A-2 is executed), and the execution time of the jackpot end demo is 30 seconds (30 seconds for the 16R specific jackpot and 4R specific jackpot, and as the jackpot end demo performance, performance B-2 and performance C are executed. However, for the 4R normal jackpot, it is 15 seconds, and as the jackpot end demo performance, performance B-1 and performance C are executed). On the other hand, if it is a jackpot in the second special symbol, regardless of the game state at the time of the jackpot, the execution time of the jackpot start demo is 5 seconds (5 seconds in any of the 16R specific jackpot, 4R specific jackpot, and 4R normal jackpot, and as the jackpot start demo performance, performance A-1 or performance A-2 is executed), and the execution time of the jackpot end demo is 20 seconds (20 seconds for the 16R specific jackpot and 4R specific jackpot, and as the jackpot end demo performance, performance B-3 is executed and performance C is not executed. However, for the 4R normal jackpot, it is 10 seconds, and as the jackpot end demo performance, performance B-1 is executed and performance C is not executed). This relationship of time values is just an example, and it is not limited to these time values as long as the magnitude relationship of each demo time in each situation is the same as the above. Also, in any of the above specifications, performance C does not occur when winning a jackpot in the high probability high base state or low probability high base state. However, if a power failure occurs during the variation related to that jackpot or during the jackpot game (special game) and the power is restored during that variation or during the jackpot game, performance C may be exceptionally generated.

[0101] The symbol display control means 155 includes a special symbol display control means 156 and a normal symbol display control means 157. The special symbol display control means 156 variably displays the first special symbol on the first special symbol display device 71 according to the variation pattern (variation time) of the first special symbol, and then fixedly displays the first special symbol after the variable display. Further, the special symbol display control means 156 variably displays the second special symbol on the second special symbol display device 72 according to the variation pattern (variation time) of the second special symbol, and then fixedly displays the second special symbol after the variable display. The special symbol display control means 156 has a special symbol game timer for managing the time (variation time, fixed display time) related to the display of the first special symbol and the second special symbol. The operating states of the first special symbol display device 71 and the second special symbol display device 72 are monitored based on the special symbol game status in the main information storage means 180. The special symbol display control means 156 generates an effect control command (referred to as a "variation stop command") for requesting the fixed display of the decorative symbol to the effect control board 200 when the variation of the special symbol stops (that is, at the timing when the value of the special symbol game timer becomes "0"). The normal symbol display control means 157 variably displays the normal symbol on the normal symbol display device 75 according to the variation pattern (variation time) of the normal symbol, and then fixedly displays the normal symbol after the variable display. The normal symbol display control means 157 has a normal symbol game timer for managing the time (variation time, fixed display time) related to the display of the normal symbol. The operating state of the normal symbol display device 75 is monitored based on the normal symbol game status in the main information storage means 180.

[0102] In addition, when the interruption state of the game continues for a predetermined time or longer, the special symbol display control means 156 generates an effect control command (referred to as a "standby demo command") that serves as an opportunity to execute a standby demo effect (customer waiting demo effect), and stores this in the command storage area of the main information storage means 180. "The interruption state of the game continues for a predetermined time or longer" means that the period during which there are no reserved balls for the operation of the special symbol and the variable display of the special symbol is not being performed continues for a predetermined time or longer. Note that when the period during which no game balls are launched continues for a predetermined time or longer, or when the period during which game balls have not entered all the winning holes continues for a predetermined time or longer, it may be configured such that the interruption state of the game continues for a predetermined time or longer.

[0103] When the result of the winning or losing determination of the special symbol is a big win, the electric accessory control means 160 outputs a control signal to the special electric accessory solenoid 543 after the confirmation display of the special symbol, and controls the opening and closing of the special electric accessory 542 according to a predetermined operation pattern as a big win game process. In the big win game, one opening and closing operation of the special electric accessory 542 is defined as one round game (unit game), and the round game is continuously executed for a specified number of rounds. The electric accessory control means 160 holds a jackpot opening counter for storing the number of operating times of the special electric accessory 542 (that is, the number of rounds in progress). Here, the end condition of the operation of the special electric accessory 542 in the big win game (the end condition of the unit game) is that a specified number of game balls (in this embodiment, "10") have entered the jackpot opening 54, or that the opening time of the jackpot opening 54 has reached the maximum opening time (in this embodiment, "29 seconds").

[0104] Further, when the result of the winning or losing determination of the normal symbol corresponds to a win, the electric accessory control means 160 outputs a control signal to the normal electric accessory solenoid 523 to open and close the normal electric accessory 522 (the second start port 52) for a predetermined release time. Here, as described above, the electric accessory control means 160 opens the normal electric accessory 522 for 0.2 seconds in the low base state where the electric chute support function (release extension function) is not operating, while in the high base state where the electric chute support function (release extension function) is operating, the normal electric accessory 522 is opened for 5.8 seconds. Here, the operating end condition of the normal electric accessory 522 is that a predetermined number (in this embodiment, "10") of game balls have entered the second start port 52, or the release time of the second start port 52 has reached the maximum release time (in this embodiment, "0.2 seconds" or "5.8 seconds").

[0105] When the result of the winning or losing determination of the first special symbol or the second special symbol is a big win, the game state control means 165 determines the game state after the end of the big win game based on the big win type (the type of symbol group) and the game state at the time of big win selection, and switches the game state after the end of the big win game. In this embodiment, as described above, as a plurality of types of game states, a normal game state (low probability low base state), a time-saving game state (low probability low base state), and a probability-variable game state (high probability high base state) are set, and any one of the plurality of types of game states is selectively set. Since each game state has already been described in detail, duplicate description is omitted here.

[0106] Further, when a big win game is executed, the game state control means 165 determines the variable pattern selection state after the end of the big win game based on the big win type (the type of symbol group), and switches the variable pattern selection state after the end of the big win game. In this embodiment, as a plurality of types of variable pattern selection states, a normal selection state, a time-saving selection state, and a probability-variable selection state are set, and any one of the plurality of types of variable pattern selection states is selectively set according to the determined game state, big win type, number of variable display times of the special symbol, etc. Since each variable pattern selection state has already been described in detail, duplicate description is omitted here.

[0107] In addition, the game state control means 165 generates an effect control command (referred to as a "game state designation command") including current game state information and variable pattern selection state information, and stores this in the command storage area of the main information storage means 180.

[0108] The error monitoring control means 170 monitors the input information of the I / O port circuit 104, inspects a magnetic detection signal by a magnetic sensor, a disconnection / short-circuit power supply abnormality signal, a radio wave detection signal by a radio wave sensor, a door / frame opening signal, etc., and determines whether the gaming machine is in an error state. When it is in an error state, in order to instruct an error state effect to the effect control board 200, it requests an effect control command (an "error effect designation command") including the error information. Although not described in FIG. 4 etc., the door opening switch is a detection means for whether the glass frame 5 is open, the frame opening switch is a detection means for whether the front frame 2 is open, and the back set opening switch is a detection means for whether the back set board 30 is open. In addition, the magnetic sensor and the radio wave sensor are detection means for discovering so-called illegal gaming acts.

[0109] The main information storage means 180 is configured to temporarily store random number value information obtained in special symbol games and normal symbol games, operation hold ball information for special symbols and normal symbols, information on game states (probability variation function, variation time shortening function, electric cheat support function) related to special symbol games and normal symbol games, information on the variable pattern selection state, result information (big win, loss) of the validity determination for special symbols and normal symbols, information on stop symbols (including symbol groups) related to special symbols and normal symbols, information on variable patterns (including variable addition patterns) for special symbols and normal symbols, information on big win games (number of rounds, opening time, opening mode (number of opening times per one-round game), etc.), status information indicating the operation states of the special symbol display devices 71, 72, status information indicating the operation state of the special electric accessory 542, information on effect control command data, etc., and has a predetermined storage area for storing each information.

[0110] When there is a command transmission request, the command transmission / reception means 190 is configured to transmit various production control command data stored in the command storage area of the main information storage means 180 to the production control board 200 in a parallel transmission system. Each production control command has a two-byte configuration including 1-byte MODE data and 1-byte EVENT data. To distinguish MODE and EVENT, Bit7 of the MODE data is set to "1" and Bit7 of the EVENT data is set to "0". When transmitting these pieces of information as valid, a strobe signal is output at the transmission timing of each of MODE and EVENT. The production control commands generated in each process are, in principle, transmitted one command per interrupt period in the order set in the command storage area of the main information storage means 180.

[0111] As shown in FIG. 4, the production control board 200 includes a production lottery random number generation means 210, a production overall control means 220, a lamp control means 230, a prop control means 240, an error production control means 250, a sub-main information storage means 260, and a command transmission / reception means 270. Note that each of the above means in the production control board 200 functionally represents what is constituted by hardware such as a sub-main CPU 201, a ROM 202, a RAM 203, and an electronic circuit arranged on the production control board 200 and software such as a control program stored in the ROM 202.

[0112] The performance lottery random number generation means 210 includes a random number counter for generating various software random numbers (performance lottery random numbers) through the program processing of the sub-main CPU 201. These random number counters serve as random number generation means for generating random numbers software-wise. Such software random numbers include the pre-reading lottery random number used for the lottery of the pre-reading performance, the decoration pattern random number used for the lottery of the stopped pattern of the decoration pattern, the variable performance pattern random number used for the lottery of the variable performance pattern of the decoration pattern, the pre-announcement lottery random number used for the lottery of the pre-announcement performance, the big win performance pattern random number used for the lottery of the big win performance pattern, the stage lottery random number used for the lottery of the transition of the performance stage, and the like. These random numbers are updated using the remaining time when command analysis is not performed within the performance control side main process described later (when the performance control command is not received from the main control board 100).

[0113] The performance overall control means 220 includes a performance mode control means 221, a hold information display control means 222, a pre-reading pre-announcement control means 223, a variable performance control means 224, a decoration pattern control means 225, a pre-announcement performance control means 226, and a special game performance control means 227.

[0114] The performance mode control means 221 controls the performance mode (also referred to as the "game performance mode") in a manner that ensures consistency with the game state and variable pattern selection state managed on the main control board 100 based on a game state designation command or the like from the main control board 100. In the present embodiment, multiple types of performance modes are set, including the "normal performance mode", the "time-saving performance mode", and the "probability-variable performance mode". Depending on the game state (or variable pattern selection state) managed on the main control board 100, the number of variable displays of special symbols, etc., one of the multiple types of performance modes is selectively set, and a variable performance corresponding to the set performance mode is executed. In the present embodiment, when the game state is the normal game state, the "normal performance mode" is set; when the game state is the time-saving game state, the "time-saving performance mode" is set; and when the game state is the probability-variable game state, the "probability-variable performance mode" is set. When any performance mode is set, as a performance (variable performance) suggesting that the player is staying in that performance mode, a background image dedicated to that performance mode (a background image that is the reverse display of the decorative symbol) is displayed on the screen, and the BGM dedicated to that performance mode is output from the speaker 11. Since the background image and BGM are set to be different for each performance mode in this way, the player can recognize which performance mode the player is currently staying in from the type of the background image or BGM.

[0115] The holding information display control means 222 has a first held ball number counter for counting the number of held balls in operation of the first special symbol and a second held ball number counter for counting the number of held balls in operation of the second special symbol. When the holding information display control means 222 receives a symbol storage number command from the main control board 100, it updates (adds) the value of the corresponding counter based on the information on the number of held balls in operation included in this command. On the other hand, when the holding information display control means 222 receives a variation start command from the main control board 100, that is, when the held balls in operation are consumed, it updates (subtracts) the value of the corresponding counter. Further, the holding information display control means 222 controls the held image display section 710 of the effect display device 70 to display the number of held images corresponding to the number of held balls in operation of the first special symbol and the number of held images corresponding to the number of held balls in operation of the second special symbol based on the values of the first held ball number counter and the second held ball number counter. Also, the holding information display control means 222 controls the variation image display area 720 of the effect display device 70 to display a variation image that switches to the held image corresponding to the held ball in operation when the held ball in operation of the first special symbol or the second special symbol (the first held ball in operation) is consumed. In the present embodiment, unless explicitly stated otherwise, the held images of the first special symbol and the held images of the second special symbol are simply referred to as "held images" without distinction, and the variation images of the first special symbol and the variation images of the second special symbol may be simply referred to as "variation images" without distinction.

[0116] The pre-reading notice control means 223 executes a pre-reading determination (referred to as "pre-reading lottery") for the operation-retained balls targeted for the pre-reading notice performance. The pre-reading notice performance is generated as a form of so-called continuous notice performance that foretells the possibility of a jackpot win or a high-expectation performance (e.g., reach performance) occurring over one or more variable displays before the operation-retained balls targeted for pre-reading are consumed. At this time, the pre-reading lottery is performed based on the information of the pre-determination result included in the pre-determination command from the main control board 100. Here, when the pre-reading notice control means 223 receives the pre-determination command from the main control board 100, it distinguishes the information of the pre-determination result of the first special symbol and the information of the pre-determination result of the second special symbol, and temporarily stores them in the pre-reading information storage area of the sub-main information storage means 260 in a form combined with the ball entry order of the operation-retained balls up to a predetermined upper limit number (4). This pre-reading information storage area has the same configuration as the retained storage area of the main control board 100, and a retained 1 storage area (the first retained storage area), a retained 2 storage area (the second retained storage area), a retained 3 storage area (the third retained storage area), and a retained 4 storage area (the fourth retained storage area) are respectively provided in the order of ball entry into each start port 51, 52. Each retained storage area can store one set of information on the pass / fail pre-determination result, the symbol pre-determination result, and the variation pattern pre-determination result. The information on the pre-determination result is stored in the order of the retained 1 storage area, the retained 2 storage area, the retained 3 storage area, and the retained 4 storage area, while being consumed in the order of the retained 1 storage area, the retained 2 storage area, the retained 3 storage area, and the retained 4 storage area (first-in, first-out principle). Also, when the information on the pre-determination result in the retained 1 storage area is consumed, the information on the pre-determination result stored in the retained 2 storage area, the retained 3 storage area, and the retained 4 storage area is respectively shifted to the storage areas with lower numbers, and the content of the retained 4 storage area is cleared to zero.

[0117] The variable effect control means 224 determines, by lottery, a variable effect pattern that defines the variable process (effect process) from the start to the stop of the variable display of the decorative pattern based on the information (such as variable pattern information and variable addition information) included in the variable start command from the main control board 100. The variable effect control means 224 holds a plurality of types of variable effect pattern tables that are referred to when selecting the variable effect pattern of the decorative pattern, and a variable effect pattern table corresponding to the variable pattern (variable time) of the special pattern is selected from among these plurality of types of variable effect pattern tables. Here, while the main variable pattern of the special pattern (such as "SP Reach A" or "SP Reach B") is determined on the main control board 100 side, on the effect control board 200 side, a sub-variable pattern of the decorative pattern (such as "SP Reach A1, A2..." or "SP Reach A2, A3...") that details the scenario of the effect display process based on the main variable pattern is determined. In the variable effect pattern of the decorative pattern, a variable display mode of the decorative pattern, that is, a scenario of a series of effect display processes from the start to the end of the variable display of the decorative pattern is defined, and the timing for generating a preview effect at each stage during the display process is also defined as a time schedule. Also, regarding this variable effect pattern of the decorative pattern, even if the variable pattern of the special pattern is the same (even when receiving a variable start command of the same information), different variable effect patterns with different effect contents can be selected if the effect mode during the stay is different. That is, the variable effect pattern table is prepared for each effect mode during the stay.

[0118] Further, when the variable effect control means 224 receives the standby demo command from the main control board 100, during the customer waiting period from the reception of the standby demo command until the variable display of the special pattern starts (until the next variable start command is received), for example, a standby demo effect (customer waiting demo effect) that plays a moving image for demonstration is executed.

[0119] The decorative symbol control means 225 determines, by lottery, the final combination of stopped symbols (left symbol, middle symbol, right symbol) of the decorative symbols based on the information (stop symbol information, game state information) included in the variation start command from the main control board 100 and the above-described variation effect pattern determined by the variation effect control means 224. In this example, three symbol columns including a plurality of types of decorative symbols are configured, and these decorative symbols are formed by identification elements such as numbers, for example. Further, the decorative symbol control means 225 holds a plurality of types of stop symbol pattern tables that are referred to when determining, by lottery, the combination of stopped symbols of the decorative symbols (also referred to as the "stop symbol pattern"). As these plurality of types of tables, there are a stop symbol pattern table for jackpot, a stop symbol pattern table for non-winning after reach, a stop symbol pattern table for non-reach non-winning, and the like. The stopped symbols of the decorative symbols are formed as a combination of three symbols and include "stop symbols indicating a jackpot (jackpot symbols)" and "stop symbols indicating a non-winning (non-winning symbols)". The jackpot symbol indicating a specific jackpot (probability-variable jackpot) is a combination of stop states in which three identical odd-numbered symbols are aligned (for example, "7·7·7"). The jackpot symbol indicating a normal jackpot (non-probability-variable jackpot) is a combination of stop states in which three identical even-numbered symbols are aligned (for example, "2·2·2"). The non-winning symbol is a combination of stop states in which at least one of the three symbols is a symbol with a number different from the other numbers (for example, "1·3·8"). Here, among the non-winning symbols, the non-winning symbol after reach is a combination of stop states in which the left symbol and the right symbol match and only the middle symbol is shifted by several frames forward and backward (for example, "3·1·3"). In addition, in the case of small jackpot symbols or jackpot symbols such as 2R jackpot symbols, it may be a combination of predetermined stop states such as "3·5·7". Further, when the lottery result is non-reach non-winning, a specific outcome (for example, as a sequential outcome, "1·2·3" or "5·6·7", or as a deviated outcome, "2·2·3" or "5·5·6") called the so-called "chance point" may be selected. Furthermore, in the above-described pseudo-continuous effect, when performing an effect of temporarily stopping and re-varying the display before finally determining the stopped symbol, a special symbol (pseudo-continuous symbol) is selected as a temporary stop symbol suggesting the occurrence of a pseudo-sequence.When displaying a pseudo-stop symbol that suggests the occurrence of a pseudo-chain, in some cases (e.g., "2·NEXT·3"), at least one of the stop symbols (typically the middle symbol) among the stop symbols of the three columns of decorative symbols is replaced with a special symbol (pseudo-chain symbol) that displays characters such as "NEXT" and then displayed. Note that the stop order for stopping the decorative symbols is predetermined for each of the following variation effect patterns. In this embodiment, in principle, the left symbol → right symbol → middle symbol are stopped in this order. However, in the case of a shortened variation effect pattern where the variation time is set extremely short, the left symbol, middle symbol, and right symbol are stopped almost simultaneously. In the case of a special variation effect pattern, they can also be stopped in the order of right symbol → middle symbol → left symbol. In this case, the jackpot expectation level tends to be relatively high. Also, regardless of the stop order, it is desirable that the left symbol, right symbol, and middle symbol start to vary simultaneously at the start of the variation. However, as a special variation effect pattern, they may also start to vary in the order of left symbol → right symbol → middle symbol.

[0120] Here, FIG. 10 is a schematic diagram showing the design attributes of the decorative design in this embodiment. The decorative design is formed by a combination of an identification element consisting of numbers and a color (display color) attached to the identification element. In this embodiment, as the identification elements, all nine types of numbers from "1" to "9" are set (that is, there are a total of nine types of decorative designs). Each decorative design is arranged in the order of "1" to "9" according to the arrangement of the design sequence, and on the effect display device 70, it is cyclically displayed or scrolled in the order of "1" to "9" (or in the order of "9" to "1") in each display area Z1, Z2, Z3, and after "9", it returns to "1" again (or after "1", it returns to "9" again). This specification is the same in other embodiments. Each decorative design has its design attribute determined by the type of color attached to the identification element. That is, even if a plurality of decorative designs are composed of different identification elements, by being attached with the same color, they will be grouped into the same design attribute. In this example, three types of colors, "blue", "red", and "gold", are set as the colors of the decorative designs. In the drawing, the display modes of the three types of decorative designs of "blue", "red", and "gold" are represented by "outline", "slant line", and "filled". Specifically, the decorative designs "2", "4", "6", "8" are classified into the blue design attribute (blue attribute), the decorative designs "1", "3", "5", "9" are classified into the red design attribute (red attribute), and the decorative design "7" is classified into the gold design attribute (gold attribute). In this embodiment, as the design attributes of the decorative designs, the expectation degree of obtaining a winning combination and the expectation degree of a probability change transition increase step by step in the order of "blue" < "red" < "gold". Hereinafter, for convenience, the decorative design with the blue attribute is also referred to as the "blue design", the decorative design with the red attribute is also referred to as the "red design", and the decorative design with the gold attribute is also referred to as the "gold design".

[0121] The preview performance control means 226 determines, by lottery, a preview performance pattern that defines the content of the preview performance executed at each stage of the change process of the decorative pattern in accordance with the scenario of the variable performance pattern determined by the variable performance control means 224. The preview performance pattern includes a performance pattern that temporarily or gradually displays an image of a specific character, an animation, etc., a performance pattern that outputs a specific sound, a performance pattern that operates a movable prop, etc. The preview performance is executed in parallel with the variable display of the decorative pattern, and pre-announces that the probability of the pattern variation stopping in the jackpot mode is high. The preview performance includes a preview performance executed before the reach state occurs (including when the reach occurs) in the process of variable display of the decorative pattern, and a preview performance executed after the reach state occurs. The preview performances have different jackpot reliabilities. Basically, the preview performance displayed after the reach occurs has a relatively higher jackpot expectation than the preview performance displayed before the reach occurs. The preview performance control means 226 holds a preview lottery table referred to when selecting the preview performance pattern for each type of preview performance, and selects the preview lottery table corresponding to the type of preview performance that occurs in accordance with the scenario of the variable performance pattern. Note that, as specific types of preview performances, for example, a comment preview performance, a background preview performance, an SU (step-up) preview performance, a logo preview performance, a mini-character preview performance, a group preview performance, a prop preview performance, etc. are prepared. This preview performance is basically performed by synthesizing the display of one or more preview performances with the variable display of the decorative pattern on the performance display device 70. Therefore, even for the variable display of the decorative pattern by the same variable performance pattern, it is possible to generate various performance modes by combining with one or more preview performances.

[0122] The special game performance control means 227 determines the contents of the performance during the jackpot (jackpot performance pattern) that notifies the player that a jackpot game is being played. The performance during the jackpot includes a jackpot start demo performance that notifies the player that a jackpot game is being played, a round performance that notifies the player that a round game is being played, and a jackpot end demo performance that notifies the player that a jackpot game is being played. When the special game performance control means 227 receives a jackpot start demo command from the main control board 100, the special game performance control means 227 determines the performance pattern during the jackpot (jackpot start demo performance pattern, round performance pattern, jackpot end demo performance pattern) based on the information on the jackpot type stored in the sub-main information storage means 260. In this jackpot performance pattern, a jackpot start demo performance time, a round performance time (performance time according to the opening pattern of the big prize opening 54), and a jackpot end demo performance time are set, and a series of performance contents are set along the time axis. In addition, the special game performance control means 227 executes a jackpot start demo performance triggered by receiving a jackpot start demo command from the main control board 100, executes each round performance triggered by receiving a round performance designation command, and executes a jackpot end demo performance triggered by receiving a jackpot end demo command, according to the jackpot performance pattern. In the jackpot start demo performance, for example, the characters "jackpot start" are displayed on the screen to announce the start of the jackpot game. In the round performance, for example, the number of currently executed rounds and the number of winning balls are displayed on the screen, and various images (such as animation images) that liven up the jackpot game are displayed. And in the jackpot end demo performance, for example, the characters "jackpot end" are displayed on the screen to announce the end of the jackpot game, and a performance indicating the game state (mode) to be transitioned to is displayed.

[0123] As described above, the performance control means 220 generates image control commands related to images and sounds based on the determined performance content (pre-reading performance pattern, variable performance pattern, advance notice performance pattern, stopping pattern pattern, jackpot performance pattern, etc.) and stores this in the command storage area of ​​the sub-main information storage means 260.

[0124] The lamp control means 230 controls the lighting and emission color of the effect lamp according to the effect content set by the effect control means 220. The lamp control means 230 holds a plurality of types of lamp data (lamp pattern data) for controlling the lighting of the effect lamp LP (frame lamp 10, panel lamp 80), reads out the lamp data corresponding to the determined effect pattern, and transmits this lamp control signal (lamp data) to the lamp connection board 91.

[0125] The accessory control means 240 controls the driving of each movable accessory 24 according to the effect content set by the effect control means 220. The accessory control means 240 holds a plurality of types of drive data for controlling the driving of the movable accessory 24, and transmits a drive control signal (drive data) corresponding to the determined effect pattern to the motor driver 92.

[0126] The error effect control means 250 is configured to determine an error effect pattern when receiving an error effect designation command from the main control board 100, and notify the gaming machine that an error state has occurred according to the error effect pattern.

[0127] The sub-main information storage means 260 is configured to temporarily store information such as decoration pattern information, variable effect pattern information, preview effect pattern information, control command information, etc., and has a predetermined storage area for storing each information. For example, the command storage area includes an effect control command buffer for storing effect control commands from the main control board 100, an image control command buffer for storing image control commands to the image control board 300, and an ACK command buffer for storing ACK commands from the image control board 300. Each command buffer is composed of a ring buffer, and can store a predetermined number of effect control commands, image control commands, and ACK commands respectively.

[0128] The command transmission / reception means 270 is configured to receive the effect control command transmitted from the main control board 100 and store this effect control command in the effect control command buffer of the sub-main information storage means 260. The command transmission / reception means 270 generates an interrupt based on the input of the aforementioned strobe signal from the main control board 100 and executes the reception interrupt process of the effect control command (details will be described later), and various effect control commands are acquired in this interrupt process. Note that when the command transmission / reception means 270 receives the strobe signal, it preferentially performs the reception interrupt process of this effect control command over other interrupt processes (interrupt processes with a priority level lower than 7, which will be described later).

[0129] Also, the command transmission / reception means 270 transmits the image control command stored in the sub-main information storage means 260 to the image control board 300 by serial communication to instruct the execution of the effect content (such as variable effect pattern information, preview effect pattern information, decorative pattern information, etc.) set by the effect general control means 220. The image control command is generally transmitted at a predetermined cycle (500 μs in this example) in the order set in the command storage area of the sub-main information storage means 260. Thereby, the image control board 300 analyzes various image control commands transmitted from the effect control board 200, variably displays an effect image including a decorative pattern on the effect display device 70 along the scenario of the variable effect pattern, and displays a preview effect in a manner superimposed on the effect of the pattern variation at each stage of the variable display process. Further, the command transmission / reception means 270 receives the ACK command transmitted from the image control board 300 and stores this ACK command in the ACK command buffer of the sub-main information storage means 260.

[0130] [Various effects] As described above, the pachinko gaming machine PA with such a configuration is configured such that various game effects are controlled and executed by the effect control board 200 and the image control board 300 according to the progress of the game and the like. Hereinafter, among various game effects, the content of the jackpot middle effect will be described. In the following, "restricting the execution" or "regulating the execution" is used as a concept including, for example, not executing all, not executing a part, and relatively lowering the priority of display or output. Also, in the following, "executing repeatedly (executing overlappingly)" means that one execution period (or execution timing) overlaps with the other execution period (or execution timing), and it is used as a concept including the case where all of the execution periods (or execution timings) of both overlap and the case where a part of the execution periods (or execution timings) of both overlap.

[0131] [Jackpot Middle Effect] As described above, the jackpot middle effect includes the jackpot start demo effect, the round effect, and the jackpot end demo effect. FIG. 11 is a schematic diagram showing the correspondence relationship between the jackpot type (type of symbol group), the jackpot symbol combination (combination of decorative symbols at the time of jackpot occurrence), and the jackpot middle effect pattern. In the figure, (A) is referred to when the game state at the time of jackpot winning is the normal game state, and (B) in the figure is referred to when the game state at the time of jackpot winning is the time-saving game state or the probability-variable game state. As shown in FIG. 11, the type of jackpot symbol combination and the type of jackpot middle effect pattern are determined according to the jackpot type (symbol group) selected in the special symbol lottery process. In the present embodiment, even when the jackpot types are the same, the type of jackpot symbol combination and the type of jackpot middle effect pattern can be different according to the game state at the time of jackpot winning.

[0132] The jackpot symbol combination is composed of a combination of stop modes " *·*·* " in which three decorative symbols of the same number (identification element) are aligned (*: decorative symbol of any number). The jackpot symbol combination is distinguished into an odd-number symbol combination (red symbol combination, gold symbol combination) indicating a "specific jackpot" such as "1·1·1", "3·3·3", "5·5·5", "7·7·7", "9·9·9", and an even-number symbol combination (blue symbol combination) indicating a "specific jackpot" or "ordinary jackpot" such as "2·2·2", "4·4·4", "6·6·6", "8·8·8". That is, the odd-number symbol combination (gold symbol combination, red symbol combination) is a jackpot symbol combination in which it is determined that a "specific jackpot" has been won, while the even-number symbol combination (blue symbol combination) is a jackpot symbol combination in which it is uncertain which jackpot type of "specific jackpot" and "ordinary jackpot" has been won.

[0133] The gold symbol combination is a jackpot symbol combination that notifies that the actual number of rounds is "16 rounds" and that the player has won the "specific jackpot" which is the trigger for shifting to the probability-variable gaming state. That is, the gold symbol combination is a jackpot symbol combination that definitely notifies that among multiple types of jackpot categories, the player has won the most advantageous jackpot (16R specific jackpot) with the highest degree of advantage for the player. The red symbol combination is a jackpot symbol combination that notifies that although it is uncertain whether the actual number of rounds is either "16 rounds" or "4 rounds", the player has won the "specific jackpot" which is the trigger for shifting to the probability-variable gaming state. The blue symbol combination is a jackpot symbol combination that notifies that although it is certain that the actual number of rounds is "4 rounds", it is uncertain whether the player has won the "specific jackpot" which is the trigger for shifting to the probability-variable gaming state or the "normal jackpot" which is the trigger for shifting to the time-saving gaming state. Here, even for the blue symbol combination, it may be configured such that the actual number of rounds can be "16 rounds" (that is, even for a probability-variable jackpot with an actual number of rounds of "16 rounds", the blue symbol combination may be selectable), but it is preferable that the red symbol combination has a higher possibility of the actual number of rounds being "16 rounds". In this case, as one of the "happy jackpot presentations" described later, a "happy jackpot C presentation" that is a probability-variable upgrade and a round upgrade may be provided.

[0134] In the present embodiment, as jackpot middle presentation patterns among multiple types of jackpots, "ultra-longevity jackpot presentation", "longevity jackpot A presentation", "longevity jackpot B presentation", "happy jackpot A presentation", and "happy jackpot B presentation" are set. The ultra-longevity jackpot presentation is a type of jackpot middle presentation pattern set corresponding to the jackpot symbol combination being the "gold symbol combination". The longevity jackpot A presentation and the longevity jackpot B presentation are types of jackpot middle presentation patterns set corresponding to the jackpot symbol combination being the "red symbol combination". The happy jackpot A presentation and the happy jackpot B presentation are types of jackpot middle presentation patterns set corresponding to the jackpot symbol combination being the "blue symbol combination". That is, the type of jackpot middle presentation pattern is set according to the symbol attribute (gold symbol, red symbol, blue symbol) of the jackpot symbol combination.

[0135] Here, with reference to FIG. 11(A), the jackpot symbol combinations and jackpot winning performance patterns selected when the game state during jackpot winning is the normal game state will be described. First, when winning the "4R specific jackpot" of the first special symbol, the "red symbol combination" or the "blue symbol combination" is selected as the jackpot symbol combination. For example, as the jackpot symbol combination, the red symbol combination is selected with a probability of 80%, and the blue symbol combination is selected with a probability of 20%. At this time, when the "red symbol combination" is selected as the jackpot symbol combination, the "Longevity Jackpot A Performance" is selected as the corresponding jackpot winning performance pattern, and when the "blue symbol combination" is selected as the jackpot symbol combination, the "Happy Jackpot B Performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "4R normal jackpot" of the first special symbol, the "blue symbol combination" is selected as the jackpot symbol, and the "Happy Jackpot A Performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "16R specific jackpot" of the second special symbol, the "gold symbol combination" is selected as the jackpot symbol, and the "Ultra Longevity Jackpot Performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "4R specific jackpot" of the second special symbol, the "red symbol combination" is selected as the jackpot symbol combination, and the "Longevity Jackpot A Performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "4R normal jackpot" of the second special symbol, the "blue symbol combination" is selected as the jackpot symbol, and the "Happy Jackpot A Performance" is selected as the corresponding jackpot winning performance pattern.

[0136] Next, referring to FIG. 11(B), the jackpot symbol combinations and jackpot winning performance patterns selected when the game state at the time of jackpot winning is the time-saving game state or the probability-variable game state will be described. When winning the "4R specific jackpot" of the first special symbol, the "red symbol combination" is selected as the jackpot symbol combination, and the "longevity jackpot A performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "4R normal jackpot" of the first special symbol, the "blue symbol combination" is selected as the jackpot symbol combination, and the "happy jackpot A performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "16R specific jackpot" of the second special symbol, the "gold symbol combination" or the "red symbol combination" is selected as the jackpot symbol combination. For example, as the jackpot symbol combination, the gold symbol combination is selected with an 80% probability, and the red symbol combination is selected with a 20% probability. At this time, when the "gold symbol combination" is selected as the jackpot symbol combination, the "ultra-longevity jackpot performance" is selected as the corresponding jackpot winning performance pattern, and when the "red symbol combination" is selected as the jackpot symbol combination, the "longevity jackpot B performance" is selected as the corresponding jackpot winning performance pattern. When winning the "4R specific jackpot" of the second special symbol, the "red symbol combination" or the "blue symbol combination" is selected as the jackpot symbol combination. For example, as the jackpot symbol combination, the red symbol combination is selected with an 80% probability, and the blue symbol combination is selected with a 20% probability. At this time, when the "red symbol combination" is selected as the jackpot symbol combination, the "longevity jackpot A performance" is selected as the corresponding jackpot winning performance pattern, and when the "blue symbol combination" is selected as the jackpot symbol combination, the "happy jackpot B performance" is selected as the corresponding jackpot winning performance pattern. Also, when winning the "4R normal jackpot" of the second special symbol, the "blue symbol combination" is selected as the jackpot symbol, and the "happy jackpot A performance" is selected as the corresponding jackpot winning performance pattern.

[0137] The ultra-longevity jackpot performance is a jackpot winning performance pattern that definitely notifies that the player has won the most advantageous jackpot (16R specific jackpot) with the highest degree of advantage among multiple types of jackpot types.

[0138] The winning-a-big-prize A performance and the winning-a-big-prize B performance have been determined to win the "specific big prize" category that triggers the transition to the probability-variable gaming state. However, until the number of rounds reaches the predetermined number of rounds (4 rounds), the performance progresses while the actual number of rounds remains uncertain as to whether it is either "16 rounds" or "4 rounds". This is the in-big-prize performance pattern. Here, even if the winning-a-big-prize A performance reaches the predetermined number of rounds (the 4th round), no upgrade performance (round upgrade performance) is carried out, and it is determined that the specified number of rounds for this big prize game is "4 rounds". On the other hand, when the winning-a-big-prize B performance reaches the predetermined number of rounds (the 4th round), an upgrade performance (round upgrade performance) occurs, and it is determined that the specified number of rounds for this big prize game is "16 rounds" (the specified number of rounds has been upgraded to "16 rounds").

[0139] The winning-a-happy-big-prize A performance and the winning-a-happy-big-prize B performance have been determined that the actual number of rounds is "4 rounds". However, until reaching the big-prize end demo, the performance progresses while it remains uncertain whether it has won the "specific big prize" that triggers the transition to the probability-variable gaming state or the "normal big prize" that triggers the transition to the time-saving gaming state. This is the in-big-prize performance pattern. Here, even if the winning-a-happy-big-prize A performance reaches the big-prize end demo, no upgrade performance (probability-variable upgrade performance) is carried out, and it is determined that the type of this big prize is "normal big prize" (after the end of this big prize game, it will transition to the time-saving gaming state). On the other hand, when the winning-a-happy-big-prize B performance reaches the big-prize end demo, an upgrade performance (probability-variable upgrade performance) occurs, and it is determined that the type of this big prize is "specific big prize" (after the end of this big prize game, it will transition to the probability-variable gaming state). Also, in Fig. 11, depending on the gaming state at the time of winning the big prize, the correspondence between the big prize type and the in-big-prize performance pattern is made different. However, regardless of the gaming state at the time of winning the big prize, the correspondence as shown in Fig. 11(B) may also be used. Also, a 16R specific big prize may be provided for the first special symbol. In that case, even when there is a big prize in the first special symbol, an ultra-winning-a-big-prize performance or a winning-a-big-prize B performance may be executed. Note that the detailed content of the upgrade performance (round upgrade performance, probability-variable upgrade performance) will be described later.

[0140] Next, the content of each jackpot winning performance pattern will be described. FIGS. 12 to 16 are schematic diagrams showing the content of the jackpot winning performance pattern. In the figures, for each jackpot winning performance pattern, the correspondence between the type of individual performance occurring during the jackpot game and the occurrence timing is defined. Note that in the figures, for ease of understanding the explanation, the opening state of the big winning opening 54 is appended. However, in the present embodiment, as the opening state of the big winning opening 54, only the "long opening" in which the opening time (maximum opening time) of the big winning opening 54 is set to an opening time that allows or facilitates the entry of game balls of the specified count number (full count) is prepared, but the present invention is not limited to this configuration, and a "short opening" in which the opening time (maximum opening time) of the big winning opening 54 is set to an opening time that makes it impossible or difficult to enter game balls of the specified count number (full count) may be prepared.

[0141] First, during the execution of the jackpot start demo, a screen suggesting the type of jackpot winning performance (ultra longevity jackpot performance, longevity jackpot performance, happy jackpot performance) is displayed, suggesting to the player which jackpot winning performance will start. In the present embodiment, the execution time of the jackpot start demo is set to "5 seconds" in common for all jackpots.

[0142] During the execution of each round game, a round performance screen corresponding to the type of jackpot winning performance (ultra longevity jackpot performance, longevity jackpot performance, happy jackpot performance) is displayed. That is, when the jackpot winning performance pattern is the ultra longevity jackpot performance, the ultra longevity jackpot round screen is displayed; when it is the longevity jackpot A performance A or the longevity jackpot B performance, the longevity jackpot round screen is displayed; and when it is the happy jackpot A performance or the happy jackpot B performance, the happy jackpot round screen is displayed. However, when the round upgrade performance described later occurs in a predetermined round game, the type of this jackpot winning performance is upgraded, and the round performance screen switches from the round performance screen of the lower rank type to the round performance screen of the higher rank type.

[0143] Note that after the end of each round game, an interval period is set, which is the pause time (closing time of the big winning opening 54) from the end of each round game to the start of the setting of the next round game or the big win end demo. Therefore, the special game is developed in the flow of "big win start demo" → "round game" → "interval period" → "round game" → "interval period" → ··· → "round game" → "interval period" → "big win end demo". In this embodiment, the interval time (interval period) is set to "2 seconds" in common for all big wins. The details of this interval time will be described later.

[0144] During the execution of the jackpot end demo, the contents of the performance mode (game state) to be transferred to after the end of the currently executed jackpot game are suggested, and the player is suggested which performance mode will be entered or continued. In addition, during this jackpot end demo period, the later-described probability change promotion performance or reserved consecutive suggestion performance may be performed. Note that the reserved consecutive suggestion performance performed during this jackpot end demo period does not include the reserved consecutive suggestion performance (the performance combined with the over winning performance or the bonus winning performance) that is performed in response to the occurrence of the over winning or the bonus winning in the modified example described later. In other words, the reserved consecutive suggestion performance related to the modified example described later is not a performance performed during the jackpot end demo period, but a performance performed during the interval period. Note that the details of the probability change promotion performance and reserved consecutive suggestion performance of this embodiment will be described later. In this embodiment, the execution time of the jackpot end demo is set to "20 seconds" in common to all jackpots. As described above, the jackpot start demo and the jackpot end demo may be configured so that each demo time is different depending on whether it is a jackpot game at the time of the first hit (i.e., a jackpot from a low probability low base state) or a jackpot game during a consecutive win (i.e., a jackpot from a high probability high base state or a low probability high base state). Specifically, each demo time may be set to a relatively short time in a jackpot game during a consecutive win, in order to proceed with the processing of the game before and after the jackpot more quickly (to proceed with the game during the consecutive win more quickly) than in a jackpot game at the time of the first hit. Also, as described above, when a performance is performed to call attention to the prevention of forgetting to take the prepaid card in a jackpot game at the time of the first hit, it is preferable to perform it within the jackpot end demo period set to a relatively long time, and when a performance is performed to call attention to the prevention of forgetting to take the prepaid card in a jackpot game during a consecutive win, it is preferable to perform it during the execution period of the round game, not during the jackpot end demo period set to a relatively short time.Regarding the hold continuous suggestion effect, in the first big win game (i.e., the big win from the low probability and low base state), it is preferable not to execute or to reduce the execution probability even if there is a big win hold within the hold. In the big win game during consecutive wins (i.e., the big win from the high probability and high base state or the low probability and high base state), it is preferable not to execute or to increase the execution probability even if there is a big win hold within the hold. Further, it is preferable that the hold continuous suggestion effect is carried out during the execution of a special game corresponding to the 16R specific big win, and it is also preferable to execute it when the big win hold within the hold is a big win hold corresponding to the 16R specific big win (that is, the big win for which the hold continuous suggestion effect is displayed and the big win hold within the hold that triggers the execution of the hold continuous suggestion effect are only targeted at the 16R specific big win, and it is preferable that the 4R specific / ordinary big win is not targeted).

[0145] Here, FIG. 17 is a schematic diagram showing the basic screen (round effect screen) during the round game. Although not shown in the figure, in the central area of the screen, various images (such as animation images) corresponding to the types of big win game effect patterns are displayed to liven up the big win game.

[0146] In the round display area 730 of the screen, the round number indicating which round game the currently executed round game is (the third round in the illustrated example) is displayed. For example, when the currently executed round game is the first round game (the first round), "ROUND1" is displayed in the round display area. When the currently executed round game is the second round game (the second round), "ROUND2" is displayed in the round display area. After that, every time the round game is played, "ROUND3", "ROUND4",... are displayed in the round display area.

[0147] In the right hitting display area 731 of the screen, a right hitting image (also referred to as a launch instruction effect) that prompts the player to launch the game ball towards the right area PA2 (right hitting) is displayed. In addition, if, contrary to this, the game ball flows down through the left area PA1 and enters the general winning holes 61 to 63, or enters the first start hole 51, that is, if the game ball is launched towards the left area PA1, an effect (warning notification effect) may be executed to alert the player not to hit the ball to the left. In the warning notification effect, a message instructing right hitting is displayed on the screen, or the effect lamp LP lights up in a special lighting mode (for example, blinking at high brightness, at high speed, or instantaneously), thereby notifying the player that the game ball should be launched towards the right area PA2 (right hitting). As the warning notification effect, for example, a voice (right hitting instruction voice) of "Please hit the ball to the right" may be output from the speaker 11. Regarding this warning notification effect, it is desirable that it be in a prominent position (for example, the central display area) and size (for example, occupying most of the display area of the effect display device 70) so that the player can clearly visually recognize it, and it should be configured to be displayable even in a situation where the right hitting image, the display content in the bonus ball acquisition display area 732 described later, the display content in the cumulative bonus ball number display area 733, the emphasis effect, and the display content in the round display area 730 are being displayed. However, since the right hitting image also conveys information (information regarding the appropriate launch position) that should be clearly communicated to the player, it is appropriate to display them in different display areas so that the right hitting image and the warning notification effect are not superimposed. On the other hand, in order not to impede the visibility of the warning notification effect, it is desirable to configure it so that the display priority is higher than the display content in the bonus ball acquisition display area 732 described later, the display content in the cumulative bonus ball number display area 733, the emphasis effect, and the display content in the round display area 730 (that is, while they can be superimposed, in that case, the warning notification effect is displayed in the front). Regarding this launch instruction effect, it is displayed with the condition that the ball enters the general winning holes 61 to 63 or the first start hole 51 during a big win, and the display time is set to 10 seconds.However, if the display condition is satisfied again before the expiration of the 10-second display time, 10 seconds will be set again as the display time from that point (i.e., the display time is extended). Also, regarding the right-hit image and the caution notification effect, it is preferable to display them not only during the jackpot but also in high-base states such as the high-probability high-base state and the low-probability high-base state. The right-hit image is continuously displayed from during the jackpot to the high-base state, and when the caution notification effect is displayed within less than 10 seconds before the end of the jackpot (for example, 5 seconds before the end of the jackpot end demonstration), it is desirable to configure it to be continuously displayed from during the jackpot to the high-base state.

[0148] In the prize ball acquisition display area 732 of the screen, when a predetermined winning (such as the over winning or the bonus winning described later) occurs, the number of prize balls (unit prize ball number) awarded based on the winning is displayed to notify that the winning has occurred. This prize ball acquisition display area 732 includes a first prize ball acquisition display area 732A where the number of prize balls acquired by the over winning (the unit prize ball number acquired when one game ball wins in the big winning port 54) is displayed when the over winning occurs, and a second prize ball acquisition display area 732B where the number of prize balls acquired by the bonus winning (the unit prize ball number acquired when one game ball wins in the general winning port 64) is displayed when the bonus winning occurs. For example, when the over winning occurs, "+15pt" corresponding to the unit prize ball number (15) of the big winning port 54 is displayed, and when the bonus winning occurs, "+3pt" corresponding to the unit prize ball number (3) of the general winning port 64 is displayed. Also, as a modification, the first prize ball acquisition display area 732A and the second prize ball acquisition display area 732B may be located separately.

[0149] In the cumulative bonus ball number display area 733 of the screen, the cumulative value of the bonus balls obtained up to the current point (referred to as the "cumulative bonus ball number") is displayed based on the entry of game balls into the big winning opening 54 or the general winning opening 64 in the big winning game during continuous winning. "Continuous winning" means the state in which, after the occurrence of the first big win that triggers the transition from the non-specific game state to the specific game state, the specific game state continues without returning to the non-specific game state (starting from the time of the first big win, and then the big wins in the specific game state occur continuously). Also, the "specific game state" is a game state in which the probability of transitioning to a special game is increased compared to the normal game state (low probability low base state), and at least one of the probability variation function of the special symbol, the function of shortening the variation time of the special symbol, and the electric chaser support function is activated (at least one of the high probability high base state, low probability high base state, and high probability low base state). In this embodiment, the game state in which at least the electric chaser support function is activated (high base state) corresponds to the "specific game state". Note that this cumulative bonus ball number also includes the bonus balls obtained by the entry of game balls into the big winning opening 54 or the general winning opening 64 in the special game when the first big win occurs. Note that this cumulative bonus ball number may or may not include the bonus balls awarded by the over winning described later. Also, this cumulative bonus ball number may or may not include the bonus balls awarded by the bonus winning described later. The over winning performance described later is executed only because it is during a big win (it can be executed because the big winning opening 54 can be opened and game balls can enter), but for the general winning opening 64, game balls can enter regardless of whether it is during a big win or not. However, the bonus winning performance described later is also configured to be executed only during a big win.Regarding the bonus winning, if it is during a big win, the bonus winning performance is executed. However, if it is in a low-probability and low-base state, a special performance different from the bonus winning (for example, a special performance where a line such as "Don't put it in here now!" is displayed and a sound is generated, but it may be generated when 3 balls enter within a predetermined time (for example, within 5 seconds) instead of 1 ball entering) is executed. If it is in a high-probability and high-base state or a low-probability and high-base state, neither the bonus winning performance nor the special performance is executed (in that case, it is not necessary to execute anything, but as another performance, a performance where a red flame briefly appears around the frame of the performance display device 70 may be executed).

[0150] In addition to or instead of this cumulative prize ball number, in one current big win game, the cumulative value of the prize balls obtained up to the present time based on the game balls entering the big winning opening 54 or the general winning opening 64 (referred to as the "big win in-game prize ball number") may be displayed. Since the big win in-game prize ball number is the number of prize balls that the player can actually obtain during the execution of one big win game, basically, it may be less than the number of available prize balls (theoretically expected prize ball number) set according to the big win type, but it will not exceed the number of available prize balls. However, when an over-winning described later occurs, the big win in-game prize ball number may exceed the number of available prize balls (theoretically expected prize ball number) set according to the big win type.

[0151] Also, although not shown in the drawings, during consecutive wins, the number of consecutive wins, which is the number of consecutive big wins in a specific gaming state or the number of times including the first big win (the number of times incremented by 1), may be displayed. As an example, if there are 3 big wins in a specific gaming state after the first big win, a display such as "3rd consecutive win" or "4th consecutive win" may be made during the big win. Also, in each round of the special game, a pseudo-decoration symbol (hereinafter referred to as "pseudo-decoration symbol") may be variably displayed and stopped (temporarily stopped display, confirmed stop display). This pseudo-decoration symbol is preferably a symbol pattern different from the normal decoration symbol variably displayed during non-special games (a symbol exclusive to during big wins). Specifically, if the decoration symbol variably displayed during non-special games is composed of a picture (character) and numbers, during special games, it becomes a decoration symbol of only numbers, and its size is also reduced, or if the decoration symbol variably displayed during non-special games is composed of only numbers, during special games, it is a decoration symbol of only the same numbers but its size is reduced. Further, when a triple such as "7·7·7" appears during a big win, as long as it can be recognized which decoration symbol resulted in the big win, "7·7·7" is not displayed during special games, and only "7" (not a combination of 3 decoration symbols but only 1 decoration symbol) needs to be displayed. Also, during the execution of the big win game (round game), the "winning-related effect" which is a characteristic effect of this embodiment is executed.

[0152] [Winning-related effect] Next, the winning-related effect of this embodiment will be described. FIG. 18 is a conceptual diagram for explaining the configuration of the winning-related effect of this embodiment. The winning-related effect is an effect executed based on a game ball entering a specific winning opening (big winning opening 54 or general winning opening 64) during the execution of the big win game. This winning-related effect includes (A) a big winning opening winning effect and (B) a general winning opening winning effect.

[0153] <A. Big winning opening winning effect> The big winning opening winning performance is a performance executed triggered by a game ball winning in the big winning opening 54 during the execution of a special game. The big winning opening winning performance includes the big winning opening normal winning performance, the big winning opening over winning performance, and the big winning opening count-up performance. In the following, unless otherwise specified, (a) a game ball winning in the big winning opening 54, (b) a game ball entering the big winning opening 54, (c) a game ball being detected by the big winning opening switch 541, and (d) receiving a big winning opening winning command from the main control board 100 are used in the same synonymous meaning.

[0154] ≪A-1. Big winning opening normal winning performance≫ The big winning opening normal winning performance is a performance that notifies that a game ball has won in the big winning opening 54 for a winning of a game ball within the specified count to the big winning opening 54. That is, the big winning opening normal winning performance is a performance that is performed every time a game ball wins in the big winning opening 54 until the number of game balls winning in the big winning opening 54 in one round of the game reaches the specified count. In this embodiment, although a specific example of the big winning opening normal winning performance is not particularly specified, a big winning opening normal winning performance using at least one of a plurality of performance means such as the performance display device 70, the speaker 11, the performance lamp LP, and the movable accessory 24 is performed. As an example, (1) display an object corresponding to the specified count in one unit game (for example, display a treasure box for the specified count within one unit game), and every time a game ball enters the big winning opening 54, the performance on the performance display device 70 where the object is deleted, (2) every time a game ball enters the big winning opening 54, the performance on the speaker 11 where a sound of "Challine" is output, (3) every time a game ball enters the big winning opening 54, the performance on the performance lamp LP where the lamp blinks twice, etc. can be mentioned. In addition, as a modification example of this embodiment, it may be configured that only the big winning opening count-up performance described later is performed for the winning of a game ball to the big winning opening 54 up to the specified count without providing the big winning opening normal winning performance.

[0155] ≪A-2. Big winning opening over winning performance≫ The big winning opening over-win performance (also referred to as the "over-win performance") is a performance that suggests or notifies that a game ball has won at the big winning opening 54, targeting the winning of game balls exceeding the specified count number to the big winning opening 54. The "over-win" means that a game ball exceeding the specified count number (the 11th and subsequent game balls in this embodiment) is detected by the big winning opening switch 541 during the execution of one round of the game. In this embodiment, although details will be described later, the effective detection period of the big winning opening switch 541 is the detection grace period after each round of the game ends (the same period as the interval period in this embodiment, but the interval period and the detection grace period may be different periods. As an example, it is the waiting time set between each round of the game or between the last round of the game and the jackpot end demo, and is the round game waiting time (unit game waiting time) or the end demo waiting time, which is the period from the start of the closing operation of the big winning opening 54 to the period when the closing is maintained. When the interval period is set to 2 seconds, the detection grace period is the period set between each round of the game or between the last round of the game and the jackpot end demo, and is the period during which the entry of game balls after the big winning opening 54 starts the closing operation (such as the entry of game balls exceeding the specified count number) can be detected. The detection grace period may be set to at least partially overlap with the interval period and may be set to 1 second or 3 seconds after the big winning opening 54 starts the closing operation). It is set until the detection grace period has elapsed, and an over-win can occur within this interval period (detection grace period). As an example of an over-win, when the 10th count game ball enters the big winning opening 54 and is detected by the big winning opening switch 541, starting the closing operation of the big winning opening 54, if a subsequent game ball (the 11th and subsequent game balls) enters the big winning opening 54 before the big winning opening 54 is closed, then when this subsequent game ball (the 11th and subsequent game balls) is detected by the big winning opening switch 541 within the interval period (detection grace period), an over-win occurs.

[0156] The types of over-winning presentations include an over-winning image display presentation and an over-winning sound output presentation. FIG. 19 is a schematic diagram showing an example of the over-winning presentation of this embodiment. Note that it is preferable that the presentation mode of the over-winning presentation is different from the presentation mode of the above-described big winning opening normal winning presentation. Further, as a modification, as a presentation related to over-winning, only an over-winning image may be mounted (without an over-winning sound), or only an over-winning sound may be mounted (without an over-winning image).

[0157] The over-winning image display presentation is a presentation for displaying an image (referred to as an "over-winning image") that suggests that an over-winning has occurred. In this embodiment, as shown in FIG. 19, an over-winning image of the character "+15pt" is displayed in the winning ball acquisition display area 732 on the screen, suggesting that "15" winning balls have been acquired based on the occurrence of an over-winning. Thereby, the player can intuitively understand that an over-winning has occurred.

[0158] The over-winning sound output presentation is a presentation for outputting a sound (an "over-winning sound") that suggests that an over-winning has occurred from the speaker 11. In this embodiment, as shown in FIG. 19, by outputting a sound effect (character voice) of "Well done" from the speaker 11, it is suggested that an over-winning has occurred.

[0159] As a modification of this embodiment, a plurality of production patterns for the over-winning performance may be provided. That is, a plurality of types of over-winning images or a plurality of types of over-winning sounds may be prepared, and any over-winning image and over-winning sound may be selected by a production lottery when an over-winning occurs. In that case, depending on the type of the over-winning image or over-winning sound, hold continuation suggestions, sure change suggestions, round number suggestions, etc. may be made. As an example, there is only one type of over-winning image, “+15pt”, while for the over-winning sound, in addition to “Yatta ne”, there are “Good job”, “Keep it up”, “Congratulations”, etc. Among them, when the over-winning sound “Congratulations” occurs, (1) the performance may also serve as a hold continuation suggestion, (2) it may also serve as a suggestion indicating that the jackpot currently being executed is a sure change jackpot, and (3) it may also serve as a suggestion indicating that the jackpot currently being executed is not a 4R jackpot but a 16R jackpot.

[0160] More specifically, as a modification of this embodiment, a configuration may be adopted in which a plurality of types of over-winning sounds are set, and in addition to the occurrence of an over-winning, it is suggested that there is a possibility of a consecutive jackpot within the hold based on the type of over-winning sound (that is, both an over-winning performance and a consecutive jackpot within the hold suggestion performance are used). Here, "consecutive jackpot within the hold" means that when the result of the winning or losing determination of a special symbol performed by the digestion of a certain preceding active hold ball is a big win, until the end of a special game executed triggered by this big win after the winning or losing determination of the special symbol related to this preceding active hold ball is permitted, one or more subsequent active hold balls existing at a predetermined timing include an active hold ball (also referred to as a "big win hold") that is scheduled to be a big win. In this modification, as a plurality of types of over-winning sounds, an over-winning sound A (a sound of "Well done") and an over-winning sound B (a sound of "Congratulations") are prepared. When there is no big win hold at the time of the occurrence of an over-winning (when the consecutive jackpot within the hold is not established), the selection rate of the over-winning sound A is "100%", and the selection rate of the over-winning sound B is "0%". On the other hand, when there is a big win hold at the time of the occurrence of an over-winning (when the consecutive jackpot within the hold is established), the selection rate of the over-winning sound A is "0%", and the selection rate of the over-winning sound B is "100%". That is, the over-winning sound A becomes a voice in a normal mode indicating that an over-winning has occurred and that the consecutive jackpot within the hold is not established. The over-winning sound B becomes a voice in a special mode indicating that an over-winning has occurred and that the consecutive jackpot within the hold is established. Note that the selection rates of the over-winning sounds A and B may be set as appropriate. For example, when there is a big win hold at the time of the occurrence of an over-winning (when the consecutive jackpot within the hold is established), the selection rate of the over-winning sound A may be "80%", and the selection rate of the over-winning sound B may be "20%". Also, in the above modification, the case where the consecutive jackpot within the hold suggestion performance is applied to the over-winning sound output performance has been illustrated and described, but the consecutive jackpot within the hold suggestion performance may also be applied to the over-winning image display performance (for example, when "+15pt" is displayed in black characters as the over-winning image display performance, the consecutive jackpot within the hold is not established or the possibility of its establishment is low, but when it is displayed in gold characters, it may be a specification where the consecutive jackpot within the hold is established or the possibility of its establishment is high).Also, regarding the above modification example, the over-winning sound B as a hold-linked suggestion was described. However, the over-winning sound B may also be designed to serve as a role of a sure-change suggestion or a round-number suggestion. In that case, depending on whether the current jackpot is a normal jackpot or a specific jackpot (sure-change jackpot), the selection rates of the over-winning sounds A and B are as follows: in the case of a normal jackpot, the selection rate of the over-winning sound A is "100%", and the selection rate of the over-winning sound B is "0%". On the other hand, in the case of a specific jackpot (sure-change jackpot), the selection rate of the over-winning sound A is "0%", and the selection rate of the over-winning sound B is "100%", or the selection rate of the over-winning sound A is "80%", and the selection rate of the over-winning sound B is "20%". Also, depending on whether the current jackpot is a 4R jackpot or a 16R jackpot, the selection rates of the over-winning sounds A and B are as follows: in the case of a 4R jackpot, the selection rate of the over-winning sound A is "100%", and the selection rate of the over-winning sound B is "0%". On the other hand, in the case of a 16R jackpot, the selection rate of the over-winning sound A is "0%", and the selection rate of the over-winning sound B is "100%", or the selection rate of the over-winning sound A is "80%", and the selection rate of the over-winning sound B is "20%".

[0161] In addition, in the present embodiment, a "Special Figure 2 Priority Consumption Method" is adopted, which preferentially consumes the operation hold balls of the second special symbol over those of the first special symbol. As the operation hold balls targeted for consecutive big wins during the hold period, only the operation hold balls of the second special symbol may be targeted. Also, when the game state at the occurrence of a big win, which is the trigger for executing a special game, is a specific game state (high base state), and the game state after the end of the special game is also a specific game state (high base state), a hold consecutive suggestion effect may be executed triggered by an over-win that occurs during the execution of the special game. Further, on the premise that the previous operation hold ball is a high-profit big win (16R big win), when a specific hold that is a high-profit big win (16R big win) is included as the earliest specific hold in the subsequent operation hold balls, a hold consecutive suggestion effect may be executed triggered by an over-win that occurs during the execution of the special game. In other words, even if there is a big win hold in the subsequent operation holds, if the big win type related to the big win hold (the earliest big win hold in the case of multiple big win holds) is a low-profit big win, the hold consecutive suggestion effect may not be executed. That is, when a hold consecutive suggestion effect occurs during the execution of a special game, it is certain that there will be consecutive big wins with a high-profit big win (16R big win) during the hold period.

[0162] As a modification of this embodiment, in addition to indicating that an over-win has occurred due to the over-win presentation, it may be suggested that there is a possibility of winning a certain-variable jackpot. That is, the over-win presentation and the certain-variable suggestion presentation may be used in combination. The certain-variable suggestion presentation is a presentation that indicates that the type of jackpot that triggered the execution of the current special game is a specific jackpot (certain-variable jackpot), that is, it indicates that the game state will shift to the certain-variable game state after the special game ends. In this modification, for example, a plurality of types of over-win sounds A to C are set. When the type of jackpot won this time is a normal jackpot, the selection rate of the over-win sound A is "70%", the selection rate of the over-win sound B is "30%", and the selection rate of the over-win sound C is "0%". Also, when the type of jackpot won this time is a specific jackpot, the selection rate of the over-win sound A is "10%", the selection rate of the over-win sound B is "30%", and the selection rate of the over-win sound C is "60%". That is, in the order of "over-win sound A" < "over-win sound B" < "over-win sound C", the certain-variable expectation level (expectation level of shifting to the certain-variable game state) increases by one level. As a further modification, instead of the certain-variable expectation level, the over-win sound may be configured to suggest the number of electric support times given after the end of the special game.

[0163] ≪A-3. Big winning opening count-up presentation≫ The big winning opening count-up effect is an effect that, when a game ball enters the big winning opening 54 during the execution of a special game while in continuous winning state, adds and displays the value of the number of bonus balls (unit bonus ball number) paid out based on the entry of the game ball into the big winning opening to the value of the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733. In this embodiment, since the specification is that "15" bonus balls are paid out when one game ball enters the big winning opening 54 (the unit bonus ball number of the big winning opening 54 is 15), when a game ball enters the big winning opening 54, the value of the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733 is updated in units of "15". Also, the special game effect control means 227 is provided with a cumulative bonus ball number counter for counting the cumulative bonus ball number. Every time a game ball enters the big winning opening 54 (every time a big winning opening winning command is received from the main control board 100), "15", which is the unit bonus ball number of the big winning opening 54, is added to the count value of the cumulative bonus ball number counter, and accordingly, the big winning opening count-up effect is performed in which "15" is added and displayed to the value of the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733. This big winning opening count-up effect is an effect that is executed regardless of whether the entry of the game ball into the big winning opening 54 is within the specified count number or exceeds the specified count number.

[0164] FIG. 20 is a schematic diagram showing a consecutive appearance example of a big winning opening count-up effect. As shown in FIG. 20, in the big winning opening count-up effect, when a game ball enters the big winning opening 54, the number of bonus balls given based on the entry of the game ball into the big winning opening 54 is added to the cumulative number of bonus balls displayed in the cumulative bonus ball number display area 733 in a count-up format by "1" in order. In the illustrated example, the cumulative number of bonus balls is displayed in a count-up manner one by one, such as "7000" → "7001" → ··· → "7014" → "7015". Note that FIG. 20 shows the flow of the big winning opening count-up effect when an over-win occurs. After the over-win effect is performed at (A) in the figure, the big winning opening count-up effect is performed at (B) to (E) in the figure. Although FIG. 20 shows the big winning opening count-up effect when an over-win effect is performed, the big winning opening count-up effect is also performed not only at the time of an over-win but also for the entry of game balls within the specified count number. Also, when the big winning opening count-up effect corresponding to the entry of game balls within the specified count number (particularly, the big winning opening count-up effect corresponding to the 10th count, which is the specified count number) is being performed and the count-up for 15 balls has not yet been completed, if an over-win occurs, it is desirable that the count-up of the big winning opening count-up effect for which the count-up for 15 balls has not yet been completed is completed (after the count for 15 balls is performed), and then the big winning opening count-up effect corresponding to the over-win is started.Here, when the over-win is detected near the end of the interval period (detection suspension period), the jackpot opening count-up effect corresponding to the over-win itself will overlap with the execution period of the next round (the next round started after the interval period has elapsed). However, even if a ball enters the jackpot opening 54 during the execution of the jackpot opening count-up effect corresponding to the over-win that is carried out during the execution of the next round (the next round started after the interval period has elapsed), when the timing of the ball entry is during the execution of the jackpot opening count-up effect corresponding to the over-win and the count-up for 15 balls has not been completed yet, after all the count-ups of the jackpot opening count-up effect for which the count-up for 15 balls has not been completed are completed (after the count for 15 balls is carried out), it is desirable to be configured such that the jackpot opening count-up effect corresponding to the winning of the jackpot opening 54 in the next round is started.

[0165] In addition, as a modification of this embodiment, when an over-win occurs during the execution of a special game, while executing the over-win effect, it may be configured not to add and display the number of bonus balls awarded based on the over-win to the cumulative number of bonus balls. That is, the cumulative number of bonus balls may be configured such that the number of bonus balls awarded based on the entry of game balls within the specified count number for the jackpot opening 54 is the target of addition and display, and the number of bonus balls awarded based on the entry of game balls exceeding the specified count number for the jackpot opening 54 is not the target of addition and display.

[0166] Also, as a modified example of this embodiment, during the execution of a special game that is executed when the first hit occurs (the result of the hit / miss judgment of the first special symbol in the normal game state becomes a big hit), even if an over winning that exceeds the specified count occurs, the over winning performance may not be executed. Also, the types of special games include a high-profit special game (e.g., 16R special game) and a low-profit special game (e.g., 4R special game), and during the execution of a high-profit special game, the over winning performance may be executed when an over winning that exceeds the specified count occurs, and during the execution of a low-profit special game, the over winning performance may not be executed even if an over winning that exceeds the specified count occurs. Also, as types of round games, there are a long open round game in which the maximum opening time of the large winning opening 54 is set to an opening time (for example, 29 seconds) at which a game ball of a specified count number (full count) can enter or is easy to enter, and a short open round game in which the maximum opening time of the large winning opening 54 is set to an opening time (for example, 2 seconds) at which a game ball of a specified count number (full count) can enter or is easy to enter, and during the execution of the long open round game, an over winning performance is executed when an over winning that exceeds the specified count occurs, and during the execution of the short open round game, an over winning performance is not executed even if an over winning that exceeds the specified count occurs. Also, during the execution of a special game executed when a specific jackpot (variable jackpot) is won, an over winning performance is executed when an over winning that exceeds the specified count occurs, and during the execution of a special game executed when a normal jackpot (non-variable jackpot) is won, an over winning performance is not executed even if an over winning that exceeds the specified count occurs.

[0167] <B.一般入賞口入賞演出> The general prize winning performance is a performance that is executed when a gaming ball wins in the general prize winning port 64. The general prize winning performance includes a general prize winning normal performance and a general prize winning port count-up performance.

[0168] ≪B-1. General prize entrance normal prize presentation≫ The general winning opening normal winning performance (also referred to as the "bonus winning performance") is a performance that suggests or notifies that a game ball has won in the general winning opening 64. In the following, when a game ball wins in the general winning opening 64 during the execution of a special game, it is also referred to as a "bonus win", but even if a game ball wins in the general winning opening 64 outside the execution of a special game (non-special game state), it may also be referred to as a "bonus win".

[0169] The types of bonus winning performances include a bonus winning image display performance and a bonus winning sound output performance. FIG. 21 is a schematic diagram showing an example of the bonus winning performance of this embodiment. As a modification, as a performance related to the bonus win, only a bonus winning image may be mounted (without a bonus winning sound), or only a bonus winning sound may be mounted (without a bonus winning image). Note that this bonus winning performance is configured to be executed even during the execution of a round game or during the closing of the big winning opening 54 during a jackpot (during the interval period), and if it is during the closing of the big winning opening 54 during a jackpot (during the interval period), it is configured to be able to be executed simultaneously with the over winning performance.

[0170] The bonus winning image display performance is a performance that displays an image (referred to as a "bonus winning image") that suggests that a bonus win has occurred. In this embodiment, as shown in FIG. 21, in the prize ball acquisition display area 732 on the screen, a bonus winning image of the character "+3pt" is displayed as the bonus winning image, suggesting that "3" prize balls have been acquired based on the occurrence of the bonus win. Thereby, the player can intuitively understand that a bonus win has occurred.

[0171] The bonus winning sound output performance is a performance that outputs a sound (the "bonus winning sound") that suggests that a bonus win has occurred from the speaker 11. In this embodiment, as shown in FIG. 21, by outputting an effect sound of "pikon" from the speaker 11, it is suggested that a bonus win has occurred.

[0172] As a modification of this embodiment, a plurality of bonus winning presentation patterns may be provided. That is, a plurality of types of bonus winning images or a plurality of types of bonus winning sounds may be prepared, and any one of the bonus winning images and bonus winning sounds may be selected by a presentation lottery when a bonus winning occurs. In that case, depending on the type of the bonus winning image or bonus winning sound, hold continuation suggestions, sure change suggestions, round number suggestions, etc. may be made. As an example, there is only one type of bonus winning image, i.e., "+3pt", while for the bonus winning sound, there are those such as "Pikon" as well as "Gachan", "Chin", and "Dokaan". Among them, when the bonus winning sound "Dokaan" occurs, (1) the presentation may also serve as a hold continuation suggestion, (2) the presentation may also serve as a suggestion indicating that the jackpot currently being executed is a sure change jackpot, and (3) the presentation may also serve as a suggestion indicating that the jackpot currently being executed is not a 4R jackpot but a 16R jackpot.

[0173] More specifically, as a modification example of this embodiment, a configuration may be adopted in which a plurality of types of bonus winning sounds are set, and in addition to the occurrence of a bonus winning, it is suggested that there is a possibility of a consecutive winning during hold based on the type of the bonus winning sound (that is, both a bonus winning effect performance and a consecutive winning during hold suggestion performance are used). In this modification example, as the plurality of types of bonus winning sounds, a bonus winning sound A (a sound effect of "Pikon") and a bonus winning sound B (a sound effect of "Dokaan") are prepared. Then, when there is no jackpot hold at the time of the occurrence of a bonus winning (when the consecutive winning during hold is not established), the selection rate of the bonus winning sound A is "100%", and the selection rate of the bonus winning sound B is "0%". On the other hand, when there is a jackpot hold at the time of the occurrence of a bonus winning (when the consecutive winning during hold is established), the selection rate of the bonus winning sound A is "0%", and the selection rate of the bonus winning sound B is "100%". That is, the bonus winning sound A becomes a voice in a normal mode suggesting that a bonus winning has occurred and the consecutive winning during hold is not established. The bonus winning sound B becomes a voice in a special mode suggesting that a bonus winning has occurred and the consecutive winning during hold is established. Further, when there is a jackpot hold at the time of the occurrence of a bonus winning (when the consecutive winning during hold is established), the selection rate of the bonus winning sound A may be "80%", and the selection rate of the bonus winning sound B may be "20%". In the modification example, the case where the consecutive winning during hold suggestion performance is applied to the bonus winning sound output performance has been illustrated and described, but the consecutive winning during hold suggestion performance may also be applied to the bonus winning image display performance (for example, when "+3pt" is displayed in black characters as the bonus winning image display performance, the consecutive winning during hold is not established or the possibility of its establishment is low, but when it is displayed in gold characters, it may be specified that the consecutive winning during hold is established or the possibility of its establishment is high).Also, regarding the above modification example, the bonus winning sound B as a holdover hint was explained. However, the bonus winning sound B may also be designed to serve as a hint for probability change or the number of rounds. In that case, depending on whether the current jackpot is a normal jackpot or a specific jackpot (probability change jackpot), the selection rates of the bonus winning sounds A and B are as follows: in the case of a normal jackpot, the selection rate of the bonus winning sound A is "100%", and the selection rate of the bonus winning sound B is "0%"; while in the case of a specific jackpot (probability change jackpot), the selection rate of the bonus winning sound A is "0%", and the selection rate of the bonus winning sound B is "100%", or the selection rate of the bonus winning sound A is "80%", and the selection rate of the bonus winning sound B is "20%". Also, depending on whether the current jackpot is a 4R jackpot or a 16R jackpot, the selection rates of the bonus winning sounds A and B are as follows: in the case of a 4R jackpot, the selection rate of the bonus winning sound A is "100%", and the selection rate of the bonus winning sound B is "0%"; while in the case of a 16R jackpot, the selection rate of the bonus winning sound A is "0%", and the selection rate of the bonus winning sound B is "100%", or the selection rate of the bonus winning sound A is "80%", and the selection rate of the bonus winning sound B is "20%".

[0174] In addition, in the present embodiment, a "special figure 2 priority digestion method" is adopted in which the operation hold balls of the second special figure are preferentially digested over the operation hold balls of the first special figure. As the operation hold balls subject to consecutive big wins during the hold, only the operation hold balls of the second special figure may be targeted. Further, when the game state at the time of a big win that triggers the execution of a special game is a specific game state (high base state), and the game state after the end of the special game is also a specific game state (high base state), a bonus winning that occurs during the execution of the special game may be used as a trigger to execute a consecutive hold suggestion effect. Further, on the premise that the preceding operation hold ball is a high-profit big win (16R big win), when a specific hold that is a high-profit big win (16R big win) is included as the earliest specific hold in the subsequent operation hold balls, a consecutive hold suggestion effect may be executed using a bonus winning that occurs during the execution of the special game as a trigger. In other words, even if there is a big win hold in the subsequent operation hold, if the big win type related to the big win hold (the earliest big win hold if there are multiple big win holds) is a low-profit big win, the consecutive big win suggestion effect may not be executed. That is, when a consecutive hold suggestion effect occurs during the execution of a special game, it is certain that there will be a consecutive big win with a high-profit big win (16R big win) during the hold.

[0175] Also, as a modification of this embodiment, in addition to indicating that a bonus win has occurred due to the bonus win presentation, it may be suggested that there is a possibility of winning a certain probability jackpot. That is, the bonus win presentation and the certain probability suggestion presentation may be used in combination. The certain probability suggestion presentation is a presentation that suggests that the type of jackpot that triggered the execution of the current special game is a specific jackpot (certain probability jackpot), that is, a presentation that suggests a transition to a certain probability game state after the end of the special game. In this modification, for example, multiple types of bonus win sounds A to C are set. When the type of jackpot won this time is a normal jackpot, the selection rate of the bonus win sound A is "70%", the selection rate of the bonus win sound B is "30%", and the selection rate of the bonus win sound C is "0%". Also, when the type of jackpot won this time is a specific jackpot, the selection rate of the bonus win sound A is "10%", the selection rate of the bonus win sound B is "30%", and the selection rate of the bonus win sound C is "60%". That is, in the order of "bonus win sound A" < "bonus win sound B" < "bonus win sound C", the certain probability expectation level (expectation level of transition to the certain probability game state) increases step by step. Additionally, as a further modification, instead of the certain probability expectation level, the bonus win sound may be configured to suggest the number of electric support times given after the end of the special game.

[0176] <<General winning opening count-up presentation>> The general winning port count-up effect is an effect in which, when a game ball enters the general winning port 64 during the execution of a special game while in a continuous winning state, the number of bonus balls (unit bonus ball number) paid out based on the entry of the game ball into the general winning port 64 is added and displayed to the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733. In the present embodiment, since the specification is such that "3" bonus balls are paid out when one game ball enters the general winning port 64 (the unit bonus ball number of the general winning port 64 is 3), when a game ball enters the general winning port 64, the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733 is updated in units of "3". Further, the special game effect control means 227 is provided with a cumulative bonus ball number counter for counting the cumulative bonus ball number as described above. Each time a game ball enters the general winning port 64 (each time a general winning port winning command is received from the main control board 100), "3" corresponding to the unit bonus ball number of the general winning port 64 is added to the count value of the cumulative bonus ball number counter, and accordingly, a general winning port count-up effect in which "3" is added and displayed to the value of the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733 is performed.

[0177] Here, FIG. 22 is a schematic diagram showing a continuous appearance example of the general winning port count-up effect. As shown in FIG. 22, the general winning port count-up effect is an effect in which, when there is an entry of a game ball into the general winning port 54, the value of the unit bonus ball number imparted based on the entry of the game ball into the general winning port 64 is added and displayed one by one in a count-up format to the current value of the cumulative bonus ball number displayed in the cumulative bonus ball number display area 733. In the illustrated example, the value of the cumulative bonus ball number is displayed in a count-up manner one by one, such as "8000" → "8001" → "8002" → "8003".

[0178] In addition, the general winning opening winning performance (bonus winning performance, general winning opening count-up performance) is performed during the execution of special games, targeting the entry of game balls into the general winning opening 64 provided in the right area PA2 among the plurality of general winning openings 61 to 64. Therefore, even if game balls enter the general winning openings 61 to 63 provided in the left area PA1 among the plurality of general winning openings 61 to 64 during the execution of special games, the general winning opening winning performance is not performed. However, when game balls enter any of the general winning openings 61 to 64 during the execution of special games, regardless of the types of the general winning openings 61 to 64 (regardless of whether the general winning opening winning performance is executed or not), the bonus balls (3 balls) based on the winning of game balls into the general winning openings 61 to 64 are paid out.

[0179] In addition, in this embodiment, every time a bonus winning occurs, the number of bonus balls (unit bonus ball number) awarded by the bonus winning is added to and displayed as the cumulative bonus ball number. However, the present invention is not limited to this configuration. Instead, the number of bonus balls (unit bonus ball number × the number of bonus winnings during one round game) based on all the bonus winnings that occurred during the execution of one round game may be collectively added to and displayed as the cumulative bonus ball number at the end of the round game. Alternatively, the number of bonus balls (unit bonus ball number × the number of bonus winnings during one special game) based on all the bonus winnings that occurred during the execution of one special game may be collectively added to and displayed as the cumulative bonus ball number at the end of the final round game or at the end of the special game.

[0180] Also, in this embodiment, a board configuration is adopted in which the general winning opening 64 is arranged upstream of the second start opening 51. However, the present invention is not limited to this configuration. Instead, a board configuration may be adopted in which the general winning opening 64 is arranged downstream of the second start opening 51. In that case, the general winning opening 64 may be arranged upstream of the big winning opening 54, or the general winning opening 64 may be arranged downstream of the big winning opening 54.

[0181] Further, as a modification of the present embodiment, the general winning opening 64 may be made to also serve as an operating opening (operating gate 53) that triggers the execution of the normal symbol lottery. That is, when a game ball enters the general winning opening 64, a normal symbol lottery is conducted to determine whether to open the second start opening 52, and a predetermined number (for example, 1 or 2) of prize balls may be paid out.

[0182] Also, as described above, the general winning opening winning performance (bonus winning performance, general winning opening count-up performance) is a performance that is triggered when a game ball enters the general winning opening 64 when the currently-executing game state is a special game state. Therefore, even if a game ball enters the general winning opening 64 when the currently-executing game state is a non-special game state, the general winning opening winning performance (bonus winning performance, general winning opening count-up performance) is not conducted. That is, even if the currently-executing game state is a game state (non-electric support state) centered around the variable display of the first special symbol, or even if the currently-executing game state is a game state (electric support state) centered around the variable display of the second special symbol, the general winning opening winning performance (bonus winning performance, general winning opening count-up performance) is not conducted when a game ball enters the general winning opening 64. Incidentally, when the currently-executing game state is a game state (electric support state) centered around the variable display of the second special symbol, on the premise that the consecutive win state continues, the cumulative prize ball count obtained in the current consecutive-win special game (the cumulative prize ball count at the end of the most recent special game) is displayed in the cumulative prize ball count display area 733 on the screen. However, in this electric support state, only the cumulative prize ball count obtained in the consecutive-win special game is displayed, and even if a game ball enters the general winning opening 64, the number of prize balls is not added and displayed to the cumulative prize ball count (the general winning opening count-up performance is not conducted), and the value of the cumulative prize ball count does not change (the cumulative prize ball count at the end of the most recent special game is maintained).

[0183] Also, during the execution of a special game that is triggered by a jackpot (when the result of the winning or losing determination of the first special symbol in the normal game state is a big win), even if a game ball enters the general winning opening 64, the bonus winning performance may not be executed. Also, as types of special games, there may be a high-profit special game (e.g., 16R special game) and a low-profit special game (e.g., 4R special game). During the execution of the high-profit special game, when a game ball enters the general winning opening 64, the bonus winning performance is executed, and during the execution of the low-profit special game, even if a game ball enters the general winning opening 64, the bonus winning performance may not be executed. Also, as types of round games, there may be a long-opening round game in which the maximum opening time of the big winning opening 54 is set to an opening time (e.g., 29 seconds) at which a game ball can enter or easily enter within the specified count number (full count), and a short-opening round game in which the maximum opening time of the big winning opening 54 is set to an opening time (e.g., 2 seconds) at which a game ball can enter or easily enter within the specified count number (full count). During the execution of the long-opening round game, when a game ball enters the general winning opening 64, the bonus winning performance is executed, and during the execution of the short-opening round game, even if a game ball enters the general winning opening 64, the bonus winning performance may not be executed. Also, during the execution of a special game that is triggered when winning a specific big win (probability-variable big win), when a game ball enters the general winning opening 64, the bonus winning performance is executed, and during the execution of a special game that is triggered when winning a normal big win (non-probability-variable big win), even if a game ball enters the general winning opening 64, the bonus winning performance may not be executed.

[0184] <Other Features of the Winning-Related Performance> Next, other features of the big winning opening winning performance and the general winning opening winning performance of this embodiment will be described. Since the big winning opening count-up performance and the general winning opening count-up performance are performances for the same display object (the cumulative prize ball number displayed in the cumulative prize ball number display area 733), hereinafter, the big winning opening count-up performance and the general winning opening count-up performance may be collectively referred to simply as the "count-up performance" in some cases.

[0185] ≪Count-Up Performance Time≫ In this embodiment, the time for incrementing the count by one winning ball (the time required for the increment from "N" to "N + 1") is set to "0.03 seconds". That is, the value of the cumulative number of winning balls displayed in the cumulative winning ball number display area 733 is incremented in increments of "0.03 seconds". Therefore, the execution time of the big winning opening count-up effect is derived by multiplying the time value required for the count-up of one winning ball by the value of the number of winning balls (unit winning ball number) given when one game ball enters the big winning opening 54. The execution time of the big winning opening count-up effect is "15 (unit winning ball number) × 0.03 seconds (count-up interval) = 0.45 seconds". Similarly, the general winning opening count-up effect is derived by multiplying the time value required for the count-up of one winning ball by the value of the number of winning balls (unit winning ball number) given when one game ball enters the general winning opening 64. The execution time of the general winning opening count-up effect is "3 (unit winning ball number) × 0.03 seconds (count-up interval) = 0.09 seconds". Hereinafter, for the sake of convenience, the execution time of the big winning opening count-up effect (the time value from the start to the end of one big winning opening count-up effect) is abbreviated as "count-up effect time A", and the execution time of the general winning opening count-up effect (the time value from the start to the end of one general winning opening count-up effect) is abbreviated as "count-up effect time B". Here, the big winning opening normal winning effect, the over-winning effect, and the bonus winning effect are configured not to be executed even during the execution of the special game, during the execution of the big win start demo, and during the execution of the big win end demo. Therefore, regarding the big winning opening count-up effect and the general winning opening count-up effect, they are also configured not to be executed even during the execution of the special game, during the execution of the big win start demo, and during the execution of the big win end demo.

[0186] (Relationship 1 of count-up effect time A) The count-up production time A is set to be shorter than the interval time (also referred to as the "interval period") set after the end of each round game. The interval time is the waiting time set between each round game or between the last round game and the jackpot end demo, and is the round game waiting time (unit game waiting time) or the end demo waiting time during which the closing operation of the big winning opening 54 starts and the closing is maintained. In the present embodiment, the interval time is set to "2 seconds" in common for all round games. In the present embodiment, by configuring the count-up production time A (0.45 seconds) to be shorter than the interval time (2 seconds), even when the count-up production for the big winning opening is performed based on the game ball entering the big winning opening 54 near the end of a certain round game, the count-up production for the big winning opening will be completed within the interval time after the end of the round game. Therefore, it is possible to reduce the possibility that the count-up production for the big winning opening extends beyond the interval period to the next round game or the jackpot end demo (if there is an over-win, there is a possibility of exceeding the interval period), and it is possible to clarify the division between each round game or the division between the last round game and the jackpot end demo.

[0187] (Relationship 2 of the count-up production time A) The count-up effect time A is set to be shorter than the execution time of the jackpot end demonstration. As described above, the count-up effect time A is set to "0.45 seconds", and the execution time of the jackpot end demonstration is set to "20 seconds" in common for all jackpot types (during-jackpot effects). The execution time of the jackpot end demonstration is the waiting time from when the interval time after the end of the last round game in the special game has elapsed until the special game ends. That is, the execution time of the jackpot end demonstration does not include the interval time set after the end of the last round game. That is, the interval time after the end of the last round game is set as the remaining time (grace time) of the round game in which it is possible that a game ball enters the big winning opening 54 within that time (detected effectively, that is, detected as a target for paying out winning balls and not determined as an illegal entry ball), but the execution time of the jackpot end demonstration is set as the preparation time for the game (effect mode) after the end of the special game separated from that round game, in which it is not possible that a game ball enters the big winning opening 54 effectively within that time. In the present embodiment, by configuring the count-up effect time A (0.45 seconds) to be shorter than the execution time of the jackpot end demonstration (20 seconds), even when the big winning opening count-up effect is performed based on a game ball entering the big winning opening 54 near the end of the last round game, and further, even when an over-win occurs in the last round game, or even after the closing of the big winning opening 54 after the last round game (even during the jackpot end demonstration period), if it is specified to perform the big winning opening count-up effect, the big winning opening count-up effect will be completed within the jackpot end demonstration period. Therefore, the big winning opening count-up effect does not extend beyond the jackpot end demonstration period to the variable display after the end of the special game, and the boundary between the end of the special game and the start of the first rotation variable display can be made clear. As a modification, for at least a part of the execution time of the jackpot end demonstration, it may be possible that a game ball enters the big winning opening 54 effectively within that time.

[0188] (Relationship 3 of the count-up effect time A) In this embodiment, when a game ball of a specified count number enters the big winning opening 54 in one round of a game, the total time of the count-up effect time A for the specified count number in this one round of the game (the big winning opening count-up effect for the number of prize balls that can be obtained in one round of the game) is configured to be shorter than the execution time of the jackpot end demonstration. Specifically, the total time of the count-up effect time A for the specified count number is "0.45 seconds (count-up effect time A) × 10 balls (specified count number) = 4.5 seconds". On the other hand, as described above, the execution time of the jackpot end demonstration is set to "20 seconds" in common for all jackpot types (jackpot in-game effects). In this embodiment, by configuring the total time of the count-up effect time A for the specified count number (4.5 seconds) to be shorter than the execution time of the jackpot end demonstration (20 seconds), even when multiple big winning opening count-up effects are continuously performed based on multiple game balls continuously entering the big winning opening 54 near the end of the final round of the game, even after the closing of the big winning opening 54 after the final round of the game (even during the jackpot end demonstration period), if the specification is such that the big winning opening count-up effect is performed, the big winning opening count-up effect will be completed within the jackpot end demonstration period. Therefore, the big winning opening count-up effect will not cross over to the variable display after the special game ends beyond the jackpot end demonstration period, and the boundary between the end of the special game and the start of the variable display in the first rotation can be clearly defined.

[0189] In addition, even when a game ball enters the big winning opening 54 in excess of the specified count in one round of the game (when an over-win occurs), it is preferable that the total time of the count-up effect time A for the cumulative count in this one round of the game (specified count + number of over-wins) is set shorter than the execution time of the big win end demo. That is, the time obtained by adding the total time of the count-up effect time A for the specified count in one round of the game and the total time of the count-up effect time A for the number of over-wins is set shorter than the execution time of the big win end demo after that round of the game. Thus, even after the closure of the big winning opening 54 after the last round of the game (even during the big win end demo period), when the specification is such that the big winning opening count-up effect is performed, even if an over-win occurs, it is preferable to end the big winning opening count-up effect within the execution time of the big win end demo to clarify the boundary between the end of the special game and the start of the variable display. Note that the number of over-wins is indefinite as it depends on the progress of the game (such as the shooting status of the game balls and the flowing status of the game balls). However, even assuming the number of over-wins is the same as the specified count, i.e., 10 balls, it is desirable to satisfy the above relationship (in that case, the time obtained by adding the total time of the count-up effect time A for the specified count in one round of the game and the total time of the count-up effect time A for the number of over-wins is 4.5 seconds + 4.5 seconds = 9 seconds, which is shorter than the execution time of the big win end demo, which is 20 seconds), and it is configured in such a way.

[0190] (Relationship 4 of the count-up effect time A) As a modification of this embodiment, when a specified number of game balls enter the big winning opening 54 in one round of the game, the total time of the count-up effect time A for the specified number of counts in this one round of the game may be configured to be shorter than the interval time after the end of the round of the game. In this modification, the total time of the count-up effect time A for the specified number of counts is "0.45 seconds (count-up effect time A) × 10 balls (specified number of counts) = 4.5 seconds". On the other hand, the interval time after the end of each round of the game is longer than the interval time (2 seconds) in the above embodiment and is set to "6 seconds" in common for all rounds of the game. In this modification, by configuring the total time of the count-up effect time A for the specified number of counts (4.5 seconds) to be shorter than the interval time (6 seconds), when a plurality of game balls continuously enter the big winning opening 54 near the end of a certain round of the game and multiple big winning opening count-up effects are continuously performed, the big winning opening count-up effect will be completed within the interval time after the end of the round of the game. Therefore, the big winning opening count-up effect will not extend beyond the interval period to the next round of the game or the big win end demo, and the separation between each round of the game or the separation between the last round of the game and the big win end demo can be clarified.

[0191] In addition, even when only one game ball enters the big winning opening 54 in a single round game exceeding the specified count (when only one over-winning occurs), it is preferable that the total time of the count-up effect time A for the cumulative count in this single round game (specified count + number of over-winnings of 1) is set shorter than the interval time after the end of the round game. That is, the time obtained by adding the total time of the count-up effect time A for the specified count in a single round game and the count-up effect time A for one over-winning (4.5 seconds + 0.45 seconds = 4.95 seconds) is set shorter than the interval time (6 seconds) after the end of that round game. Thus, even when an over-winning occurs, it is preferable to end the big winning opening count-up effect within the interval period to clarify the separation between round games.

[0192] (Relationship 5 of the count-up effect time A) As a modification of this embodiment, when game balls corresponding to the specified count number (full count) enter the big winning opening 54 in all round games of a single special game, the total time of the count-up effect time A corresponding to the number of full counts (specified number of rounds × specified count number) generated during the execution of this special game may be configured to be shorter than the execution time of the jackpot end demonstration. In this modification, when the specified number of rounds of a single special game is the maximum number of rounds (16 rounds), and when game balls enter the big winning opening by the specified count number (10 balls) in all round games, a total of 160 big winning opening count-up effects are executed. Therefore, the total time of the count-up effect time A corresponding to all count numbers is "0.45 seconds (count-up effect time A) × 10 balls (specified count number) × 16 rounds (specified number of rounds) = 72 seconds". On the other hand, in this modification, the execution time of the jackpot end demonstration is set to "120 seconds" commonly for all jackpot types (jackpot in-game effects). In this modification, by configuring the total time of the count-up effect time A corresponding to all count numbers in a single special game (72 seconds) to be shorter than the execution time of the jackpot end demonstration (120 seconds), even after the closing of the big winning opening 54 after the last round game (even during the jackpot end demonstration period), when it is specified to perform the big winning opening count-up effect, even if the execution of the big winning opening count-up effect is delayed during the round game or the interval period due to consecutive winning of game balls into the big winning opening 54, it is guaranteed that all big winning opening count-up effects will be completed at least by the end of the jackpot end demonstration. Therefore, it becomes possible to smoothly advance the in-game effects during the jackpot.

[0193] ≪Priority of count-up effects for the front and rear big winning openings≫ FIG. 23 is a time chart for explaining the priority of the big winning opening count-up effect. As shown in FIG. 23, during the execution of a certain round of the game, when a plurality of game balls (two game balls in the illustrated example) continuously enter the big winning opening 54, two big winning opening count-up effects based on the consecutive wins will be executed. Specifically, when the first game ball enters the big winning opening 54 and the execution condition of the big winning opening count-up effect is satisfied, the previous big winning opening count-up effect is executed. Similarly, when the second game ball wins by entering the big winning opening 54 and the execution condition of the big winning opening count-up effect is satisfied, the subsequent big winning opening count-up effect will be executed. The execution condition of the big winning opening count-up effect is a condition for starting the execution of the big winning opening count-up effect, and it is established when a game ball enters the big winning opening 54 during the execution of a special game (when the entry of the game ball is detected by the big winning opening switch 541). At this time, if the execution condition of the subsequent big winning opening count-up effect is satisfied during the execution of the previous big winning opening count-up effect, the execution of the previous big winning opening count-up effect will not be interrupted halfway, and after the execution of the previous big winning opening count-up effect is completed, the execution of the subsequent big winning opening count-up effect will be started. That is, in the present embodiment, among the two big winning opening count-up effects, the priority of the previous big winning opening count-up effect is set higher than the priority of the subsequent big winning opening count-up effect. Before the execution of the previous big winning opening count-up effect is completed, the execution of the subsequent big winning opening count-up effect will not be started, and after the execution of the previous big winning opening count-up effect is completed, the execution of the subsequent big winning opening count-up effect is configured to be started. Incidentally, when starting the execution of the subsequent big winning opening count-up effect after the execution of the previous big winning opening count-up effect is completed, it is preferable to connect the previous big winning opening count-up effect and the subsequent big winning opening count-up effect continuously (seamlessly) to continuously perform the big winning opening count-up for two times.However, as a modification example, after the execution of the previous big winning opening count-up effect is completed, after a predetermined time (a very short time) has elapsed, the execution of the subsequent big winning opening count-up effect may be started to clearly separate between the previous big winning opening count-up effect and the subsequent big winning opening count-up effect. Although the big winning opening count-up effect has been described here, the general winning opening count-up effect may have the same specifications. When the execution conditions for the subsequent general winning opening count-up effect are satisfied during the execution of the previous general winning opening count-up effect, it is preferable to configure it such that the execution of the subsequent general winning opening count-up effect is started after the execution of the previous general winning opening count-up effect is completed without interrupting the execution of the previous general winning opening count-up effect in the middle. Also, when the execution conditions for the subsequent general winning opening count-up effect are satisfied during the execution of the previous big winning opening count-up effect, it is preferable to configure it such that the execution of the subsequent general winning opening count-up effect is started after the execution of the previous big winning opening count-up effect is completed without interrupting the execution of the previous big winning opening count-up effect in the middle. Further, when the execution conditions for the subsequent big winning opening count-up effect are satisfied during the execution of the previous general winning opening count-up effect, it is preferable to configure it such that the execution of the subsequent big winning opening count-up effect is started after the execution of the previous general winning opening count-up effect is completed without interrupting the execution of the previous general winning opening count-up effect in the middle.

[0194] As a modification of this embodiment, during the execution of the previous big winning opening count-up effect, if the execution conditions for the subsequent big winning opening count-up effect are satisfied, the execution of the previous big winning opening count-up effect may be interrupted and the execution of the next big winning opening count-up effect may be started. That is, the priority of the subsequent big winning opening count-up effect is set higher than that of the previous big winning opening count-up effect. In that case, when the execution of the previous big winning opening count-up effect is interrupted, it is preferable to forcibly switch the count value to the final value of the previous big winning opening count-up effect or the initial value of the subsequent big winning opening count-up effect, and start the subsequent big winning opening count-up effect from that point. Although this modification has been described for the big winning opening count-up effect, the general winning opening count-up effect may have the same specification. During the execution of the previous general winning opening count-up effect, if the execution conditions for the subsequent general winning opening count-up effect are satisfied, the execution of the previous general winning opening count-up effect may be interrupted and the execution of the next general winning opening count-up effect may be started. Also, during the execution of the previous big winning opening count-up effect, if the execution conditions for the subsequent general winning opening count-up effect are satisfied, the execution of the previous big winning opening count-up effect may be interrupted and the execution of the next general winning opening count-up effect may be started. Further, during the execution of the previous general winning opening count-up effect, if the execution conditions for the subsequent big winning opening count-up effect are satisfied, the execution of the previous general winning opening count-up effect may be interrupted and the execution of the next big winning opening count-up effect may be started.

[0195] (Accumulated prize ball number emphasis effect) FIG. 24 is a schematic diagram for explaining the highlighting effect of the present embodiment. (A) in the figure shows the case where the over-winning effect is executed during the execution of the highlighting effect, and (B) in the figure shows the case where the bonus-winning effect is executed during the execution of the highlighting effect. In the present embodiment, when a game ball enters the big winning opening 54 or the general winning opening 64 during the execution of a special game, when the value of the cumulative winning balls during continuous winning reaches a predetermined specific value, a highlighting effect for notifying that the cumulative winning balls have reached the specific value is configured to be executed. Note that the specific value is a multiple value of a predetermined number of winning balls (10,000 balls). That is, every time the current value of the cumulative winning balls reaches a multiple value of the predetermined number of winning balls (10,000 balls, 20,000 balls, 30,000 balls...), the highlighting effect will be performed. Therefore, the highlighting effect may also be referred to as a specific value reaching effect, and the highlighting display may also be referred to as a specific value corresponding display. In the present embodiment, even when the cumulative winning balls reach a specific value triggered by an over-winning or a bonus-winning, the highlighting effect is executed. In that case, the highlighting effect and the over-winning effect or the bonus-winning effect are executed repeatedly.

[0196] As shown in FIG. 24, the types of the highlighting effect include a highlighting display effect of enlarging and displaying the specific value (in the illustrated example, "20,000 pt") at which the cumulative winning balls have arrived in the highlighting display area 735 in the center of the screen, and a highlighting sound output effect of outputting a special sound (in the illustrated example, the sound of "excellent condition") from the speaker 11.

[0197] The highlighting of a specific value is continuously performed for a predetermined time (e.g., 5 seconds). Even if the cumulative prize ball number display is updated (added) due to the entry of a game ball into the big winning opening 54 or the general winning opening 64 during that time, the highlighting will not be updated (added). At this time, the display priorities of each layer are in the order of "cumulative prize ball number display" < "highlighting" < "round display", with the priority increasing. The "layer" means each layer of the hierarchical structure that defines the display priority of each image constituting the overall image. Each layer is arranged in the upper layer (front side as seen by the player) with a higher display priority, and in the lower layer (rear side as seen by the player) with a lower display priority. In FIG. 24, the highlighting and the cumulative prize ball number display are shown in a non-overlapping form, but the display area can be expanded to further emphasize the highlighting and they can be shown in an overlapping form. In that case, according to the above priorities, the highlighting can be configured to be displayed in front of the cumulative prize ball number display (covering part or all of the cumulative prize ball number display).

[0198] Also, as shown in FIG. 24, the prize ball acquisition display area 732 and the highlighting display area 735 are provided as separate and independent display areas. When an over-win or bonus win occurs during the execution of the highlighting, the highlighting image and the over-win image or bonus win image are displayed simultaneously in parallel. When the highlighting image and the over-win image or bonus win image are displayed simultaneously, the display priority of the highlighting image can be set higher than that of the over-win image or bonus win image, or the display priority of the over-win image or bonus win image can be set higher than that of the highlighting image. In FIG. 24, the highlighting and the over-win image / bonus win image are shown in a non-overlapping form, but the display area can be expanded to further emphasize the highlighting and they can be shown in an overlapping form. In that case, according to the above priorities, the highlighting can be configured to be displayed in front of the over-win image / bonus win image (covering part or all of the over-win image / bonus win image).

[0199] Also, when an over-win occurs during the output of a special sound, an over-win sound or a bonus-win sound is output repeatedly during the output of the special sound. When the special sound overlaps with the over-win sound or the bonus-win sound, the volume of the over-win sound or the bonus-win sound may be set to a smaller volume compared to the volume of the special sound with higher priority, and conversely, the volume of the special sound may be set to a smaller volume compared to the volume of the over-win sound or the bonus-win sound with higher priority. In that case, the volume of the lower-priority sound (the smaller volume) may be set to substantially "0".

[0200] <<Over-win performance / Bonus-win performance at error occurrence>> In this embodiment, when various errors occur in the gaming machine, it is configured to control whether to execute the over-win performance and the bonus-win performance according to the error type. FIG. 25 is a schematic diagram for explaining the error types of the gaming machine. In this embodiment, as the error types that occur in the gaming machine, "door / frame opening error", "magnetic sensor error", "radio wave sensor error", "disconnection / short-circuit power supply error", "excessive win error", "payout error", etc. are set. Note that the above error types are just examples, and various error types may be provided according to the specifications of the gaming machine and the like.

[0201] The door / frame opening error occurs when the glass frame 5, the front frame 2, or the back set board 30 is open with respect to the outer frame 1, or when a disconnection or failure occurs in the door opening switch that detects the opening of the glass frame 5, the frame opening switch that detects the opening of the front frame 2, or the back set opening switch that detects the opening of the back set board 30. This door / frame opening error is confirmed to check if there is any abnormality in the gaming machine and is released when the glass frame 5, the front frame 2, and the back set board 30 are closed.

[0202] The magnetic sensor error and the radio wave sensor error occur when the magnetic sensor detects magnetism, when the radio wave sensor detects radio waves, and when a disconnection, short circuit, or failure occurs in the magnetic sensor or the radio wave sensor. The magnetic sensor error and the radio wave sensor error are confirmed to check if there is any abnormality in the gaming machine and are released when the power is turned on again.

[0203] The open circuit / short circuit power supply error is an error that occurs when an open circuit, short circuit, or failure occurs in the radio wave sensor and various switches provided on the game board surface. The open circuit / short circuit power supply error is released when it is confirmed that there is no abnormality in the gaming machine and the power is turned on again.

[0204] The excessive winning error is an error that occurs when a game ball enters various winning openings in excess. The excessive winning error is released when it is confirmed that there is no abnormality in the gaming machine and the power is turned on again. Here, the excessive winning error includes the excessive winning error of the big winning opening 54 (also referred to as the "big winning opening excessive winning error"), the excessive winning error of the general winning openings 61 to 64 (also referred to as the "general winning opening excessive winning error"), and the like. For example, the big winning opening excessive winning error is an error that occurs when a game ball enters the big winning opening 54 by a predetermined number (for example, 30 balls) during the execution of one round of the game. The general winning opening excessive winning error is an error that occurs when a game ball enters the general winning openings 61 to 63 by a predetermined number (for example, 30 balls) per unit time (for example, 30 seconds), or when a game ball enters the general winning opening 64 by a specific number (for example, 60 balls) per unit time (for example, 30 seconds). Since the general winning opening 64 is arranged such that game balls are more likely to enter than the general winning openings 61 to 63, the general winning opening 64 has a more generous numerical value as the error determination value (the value of the number of game balls determined to be an error) based on the number of balls entering per unit time. In the present embodiment, when the big winning opening excessive winning error occurs, or when a game ball enters the big winning opening 54 in a state where the big winning opening 54 is not open (during non-special games), that is, when an abnormal winning related to the big winning opening 54 is detected (when it is determined to be an abnormal winning), an external information signal (security signal) indicating that an error has occurred is output from the external information terminal board 600. On the other hand, when the general winning opening excessive winning error occurs, that is, when an abnormal winning related to the general winning openings 61 to 64 is detected (when it is determined to be an abnormal winning), an external information signal (security signal) indicating that an error has occurred is not output from the external information terminal board 600. The external information signal (outer end signal) output by the external information terminal board 600 will be described later.

[0205] The payout error is an error that occurs when there is an obstruction in the payout of the bonus balls. This payout error includes a full-ball error where the lower ball tray 9 is full of game balls (the full-ball switch is on), a ball jamming / blockage error in the bonus ball payout unit 34, and a no-ball error where game balls cannot be replenished from the game island and there is a shortage. When a full-ball error occurs, the notification level is divided into two stages. Notification level 1 is the level when the full-ball switch has been on for 30 consecutive seconds since it was turned on. At notification level 1, only an audio notification of "Please remove the balls" is executed. At this notification level 1, even if there is a ball entry into the big winning opening 54 or the general winning openings 61 - 64, the bonus ball payout is not restricted (the bonus ball payout does not stop). When the on state exceeds 30 seconds, it shifts to notification level 2, and not only an audio notification of "Please remove the balls" but also an image notification of "An image prompting the removal of balls from the lower ball tray" is displayed on the effect display device 70. Furthermore, even if there is a ball entry into the big winning opening 54 or the general winning openings 61 - 64, the bonus ball payout is restricted (the bonus ball payout stops). As a modified example, it may be a specification where only an image notification is made at notification level 1 and both an image notification and an audio notification are made at notification level 2. Regarding the ball jamming / blockage error in the bonus ball payout unit 34 and the no-ball error where game balls cannot be replenished from the game island and there is a shortage, even if there is a ball entry into the big winning opening 54 or the general winning openings 61 - 6...
