It should be noted that each configuration illustrated in FIGS. 1 to 5 is merely what is necessary for explaining the gaming machine 10 of the present embodiment, and configurations and functions not illustrated here may be added to the gaming machine 10. Also, the gaming machine 10 does not necessarily have to include all of the configurations illustrated here, and some configurations or functions may be omitted as long as the effects of the present invention are not impaired.

[0018] The gaming machine 10 of the present embodiment is a so-called pachinko machine that fires a game ball into the front area of the game board 50 (hereinafter referred to as the "game area 50a") where a large number of game pins (not shown) are erected, and a prize ball is obtained when the game ball enters a winning hole (for example, the big winning hole 55, etc.). In the following description, the entry of a game ball into a winning hole may be simply expressed as "winning (into the winning hole)".

[0019] The gaming machine 10 includes a rectangular frame-shaped outer frame 15 that opens to the front and rear, an intermediate frame 17 that detachably holds a game board 50 on the front opening side of the outer frame 15, and a front frame 20 configured to cover the front side of the game board 50.

[0020] The intermediate frame 17 is rotatably supported about the left end side by a hinge mechanism (not shown) on the same side as the hinge mechanism 21, and can be opened and closed on the front side of the outer frame 15. The intermediate frame 17 can be locked and unlocked by a cylinder lock 23 (insert a door key into the cylinder lock 23 and turn the door key in a direction opposite to the unlocking direction of the front frame 20 (right in this embodiment)).

[0021] The front frame 20 is rotatably supported about the left end side by the hinge mechanism 21 and can be opened and closed with respect to the intermediate frame 17. The front frame 20 can be locked and unlocked by a cylinder lock 23 (insert a door key into the cylinder lock 23 and turn the door key in a direction opposite to the unlocking direction of the intermediate frame 17 (left in this embodiment)). Further, the front frame 20 includes a transparent member 25 disposed to cover the game area 50a, and the transparent member 25 provides perspective protection for the game area 50a and the game board 50. Further, the front frame 20 includes an upper ball receiver 27 and a lower ball receiver 29 for storing game balls, and the upper ball receiver 27 and the lower ball receiver 29 are vertically spaced apart and provided integrally with the front frame 20. In this embodiment, a full detection sensor (not shown) for detecting that the lower ball receiver 29 is full with the game balls discharged is provided upstream of the lower discharge port 30 for discharging the game balls to the lower ball receiver 29. Further, the front frame 20 includes an operation handle 31 on the right side of the lower ball receiver 29, and by rotating the operation handle 31, the game balls stored in the upper ball receiver 27 are launched toward the game area 50a.

[0022] Although illustration is omitted in FIGS. 1 to 5, the middle frame 17 is provided with a middle frame door opening sensor 76 for detecting whether the middle frame 17 is in an open state or a closed state with respect to the outer frame 15, and a front frame door opening sensor 77 for detecting whether the front frame 20 is in an open state or a closed state with respect to the middle frame 17. In the present embodiment, all of these door opening sensors turn ON in the open state and turn OFF in the closed state. However, these door opening sensors may be configured to turn OFF in the open state and turn ON in the closed state. Thereby, the gaming machine 10 can detect both the opening / closing state of the middle frame 17 with respect to the outer frame 15 and the opening / closing state of the front frame 20 with respect to the middle frame 17.

[0023] Also, as shown in FIG. 3, an operation button group operated by the player is arranged on the upper surface of the upper ball receiving tray 27. In this operation button group, as a main operation unit 39 electrically connected to a main control board 100 described later, a ball lending button 39a and a return button 39b for receiving a return operation of a prepaid card are provided. As an operation unit electrically connected to a first sub-control board 200 described later, an effect button 37 for receiving an operation of the player for switching an effect generated during the game or obtaining various information related to the gaming machine 10, and cursor buttons 38 (an upper cursor button 38a, a lower cursor button 38b, a left cursor button 38c, a right cursor button 38d, and a middle cursor button 38e) for instructing operations in the up, down, left, and right directions, etc. are included. Note that each operation unit is provided with a sensor for detecting an operation, and the control board to be connected detects the operation of each operation unit based on a change in the detection state of the sensor. Furthermore, a movable decorative body 22 that operates (vibrates) by an actuator such as a motor (not shown) is provided on the side of the upper ball receiving tray 27. The movable decorative body 22 also has a function of lighting by a full-color LED provided inside thereof, and a function as a button for receiving an operation of the player similar to the effect button 37. Note that these functions are also possessed by the above-described effect button 37.

[0024] Below the lower ball receiving tray 29, a ball discharging mechanism 36 for discharging the game balls stored in the lower ball receiving tray 29 downward is provided. By operating this ball discharging mechanism 36, a bottom opening (not shown) formed on the bottom surface of the lower ball receiving tray 29 opens, and the game balls naturally fall and are discharged from the bottom opening. Although not shown, the upper ball receiving tray 27 is provided with a mechanism that, similar to the ball discharging mechanism 36, moves the stored balls to the lower ball receiving tray 29 by operation. By operating both this mechanism and the ball discharging mechanism 36, it becomes possible to discharge the stored balls.

[0025] As shown in FIG. 1, a pair of speakers 33 (33a, 33b) are respectively disposed on the left and right sides of the upper frame portion 32 of the front frame 20. Further, the upper frame portion 32 and the left and right side frame portions 34a, 34b of the front frame 20 are formed of a light-transmissive cover, and frame lamps 35 (35a, 35b, 35c) are respectively disposed inside thereof. The speakers 33 and the frame lamps 35 can emit sound, light up, or go out in conjunction with effects and error notifications generated during the game.

[0026] The effect display device 80 is composed of a main display portion 81 disposed substantially at the center of the game board 50 and sub-display portions 82 disposed around the main display portion 81. The sub-display portions 82 further include an upper sub-display portion 82a disposed above the main display portion 81, a left sub-display portion 82b disposed on the left side of the main display portion 81, and a right sub-display portion 82c disposed on the right side of the main display portion 81. Here, the main display portion 81 is a fixed liquid crystal display device, and the upper sub-display portion 82a, the left sub-display portion 82b, and the right sub-display portion 82c are movable liquid crystal display devices that operate by an actuator such as a motor (not shown).

[0027] The main display portion 81 can display the variation display of a symbol sequence that is performed in conjunction with the variation display in the first special symbol display device 91 or the second special symbol display device 92, which will be described later, and can also display various other effects. In the variable display of the symbol sequence (decorative symbol) displayed on the main display unit 81, the displayed decorative symbol forms three symbol sequences. Although the direction of the variable display of each symbol sequence in the present embodiment is downward, the direction is not particularly limited. For example, it may be any of upward, left - right direction, depth direction, or a combination thereof (diagonal direction). Here, the depth direction refers to a virtual direction recognized by the player in a display mode using a technique (for example, perspective method) that makes the player recognize that the symbol sequence is variably displayed from the back to the front direction or the reverse direction of the main display unit 81, even though it is actually a planar variable display on the display screen of the main display unit 81. In addition, the decorative symbols in the present embodiment include a "1 symbol" imitating the number "1", a "2 symbol" imitating the number "2", a "3 symbol" imitating the number "3", a "4 symbol" imitating the number "4", a "5 symbol" imitating the number "5", a "6 symbol" imitating the number "6", a "7 symbol" imitating the number "7", an "8 symbol" imitating the number "8", and a "9 symbol" imitating the number "9". These symbols are provided in each symbol sequence. In the following description, the "1 symbol", "3 symbol", "5 symbol", "7 symbol", and "9 symbol" may be collectively referred to as "odd symbols", and the "2 symbol", "4 symbol", "6 symbol", and "8 symbol" may be collectively referred to as "even symbols".

[0028] Each of the sub - display units 82 is provided not only mainly for displaying effect images related to effects but also is configured to be movable. Note that the initial position of each is such that the upper sub - display unit 82a is above with respect to the main display unit 81, the left sub - display unit 82b is on the left with respect to the main display unit 81, the right sub - display unit 82c is on the right with respect to the main display unit 81, and each of the sub - display units 82 is configured to be movable from these initial positions to a position where the entire display area of the sub - display unit 82 overlaps the display area of the main display unit 81. However, even in the initial position shown in FIG. 4, the sub - display unit 82 (particularly, the left sub - display unit 82b and the right sub - display unit 82c) has approximately the upper half of the display area (the left display area 821 and the right display area 822 described later) visible to the player.

[0029] On the lower right side of the main display unit 81, a plurality of light emitting diodes (hereinafter abbreviated as "LEDs") are arranged, and the display area of the symbol display device 90 is constituted by these LEDs. Special symbols and normal symbols are displayed on the symbol display device 90. In addition, the symbol display device 90 is arranged at a position where it is difficult for the player to visually recognize compared to the main display unit 81, and the display area of the symbol display device 90 has a smaller area than the display area of the main display unit 81. Note that the arrangement and number of the LEDs related to the symbol display device 90 in the present embodiment are as shown in FIG. 2, but this is only an example, and the arrangement and number of the LEDs related to the symbol display device 90 are not limited to this example.

[0030] The special symbol is a symbol that is stopped and displayed as a result of symbol variation that determines whether or not to operate a special electric accessory (for example, the special electric accessory 65). The special symbols in the present embodiment include a first special symbol displayed on the first special symbol display device 91 and a second special symbol displayed on the second special symbol display device 92. Note that the special symbol may be abbreviated as "special symbol", the first special symbol may be abbreviated as "special symbol 1", and the second special symbol may be abbreviated as "special symbol 2".

[0031] The normal symbol is a symbol that is stopped and displayed as a result of symbol variation that determines whether or not to operate a normal electric accessory (for example, the normal electric accessory 61). The normal symbol in the present embodiment is displayed on the normal symbol display device 93. Note that the normal symbol may be abbreviated as "normal symbol", and the normal electric accessory may be referred to as "electric chew".

[0032] In addition, on the symbol display device 90, in addition to the above-described display devices, a first special symbol hold lamp 94, a second special symbol hold lamp 95, and a normal symbol hold lamp 96 are provided. The first special symbol hold lamp 94 enables identification of the number of symbol variations related to the special symbol 1 on hold, the second special symbol hold lamp 95 enables identification of the number of symbol variations related to the special symbol 2 on hold, and the normal symbol hold lamp 96 enables identification of the number of symbol variations of the normal symbol on hold. In each case, the number of corresponding symbol variations can be identified by the lighting modes of two LEDs (in this embodiment, only the right LED always lit = 1, both the left and right LEDs always lit = 2, the right LED blinking + the left LED always lit = 3, both the left and right LEDs blinking = 4).

[0033] In the following description, the symbol variation in which the special symbol is stopped from being variably displayed after being variably displayed by the first special symbol display device 91 or the second special symbol display device 92 is referred to as "symbol variation of the special symbol", and in the following description, the symbol variation in which the normal symbol is stopped from being variably displayed after being variably displayed by the normal symbol display device 93 may be referred to as "symbol variation of the normal symbol". Also, in the following description, the variable display of the symbol sequence (decorative symbol) displayed on the main display unit 81 described above may be referred to as "symbol variation of the decorative symbol" separately from "symbol variation of the special symbol" and "symbol variation of the normal symbol". In the following description, when simply referred to as "symbol variation", it means the symbol variation of the special symbol unless otherwise specified.

[0034] On the front surface of the game board 50, as shown in FIG. 4, a game area 50a is defined so that the launched game balls roll due to the arrangement of a number of game pins (not shown), a windmill 52, and obstacles such as decorative members. Also, on the left side and upper side of the game area 50a, a curved outer rail 51 and an inner rail 53 are arranged to guide the game balls launched by the rotational operation of the operation handle 31 to the upper part of the game area 50a. The outer rail 51 is located outside the inner rail 53 with respect to the center of the game area 50a. Here, the windmill 52 is a mechanism for changing the direction of the fall of the game balls and is in the shape of a nail.

[0035] The gaming machine 10 can adjust the strength of hitting out game balls according to the magnitude of the rotational operation amount (e.g., rotational angle) of the operation handle 31. Various obstacles are arranged in the game area 50a so that the game ball rolls through either the first flow path X (so-called left hit) where the game ball is hit out more weakly and rolls, or the second flow path Y (so-called right hit) where the game ball is hit out more strongly and rolls.

[0036] Fig. 4 shows, as main winning openings, the big winning opening 55, the first start opening 57, the second start opening 59, the gate 63, and the general winning opening 67. However, the shown winning openings are just examples, and the number and arrangement thereof may be changed as appropriate.

[0037] The big winning opening 55 is arranged at the lower right part of the game area 50a. A big winning opening sensor 72 is attached to the big winning opening 55. Whether a ball wins through the big winning opening 55 is determined based on the detection result of the big winning opening sensor 72, and a number (15 in this embodiment) of prize balls corresponding to the big winning opening 55 are awarded. In this embodiment, the obstacles are arranged such that more game balls roll toward the big winning opening 55 when rolling from the second flow path Y compared to when rolling from the first flow path X.

[0038] A special electric accessory 65 is arranged above the big winning opening 55. The special electric accessory 65 is a member that can be switched between an open state where it is easy for a ball to win through the big winning opening 55 and a closed state where it is difficult for a ball to enter, and it transitions to either the open state or the closed state by a special electric accessory solenoid 66. More specifically, the special electric accessory 65 becomes open in part of the jackpot game started due to a jackpot being derived by the special drawing win / loss determination described later, or in part of the minor win game started due to a minor win being derived by the special drawing win / loss determination, and accordingly, winning at the big winning opening 55 is permitted. Thus, when the special electric accessory 65 is in the open state, since winning at the big winning opening 55 becomes easy, it can be said that the jackpot game and the minor win game, in which the opportunity to obtain prize balls significantly increases, are in an advantageous game state. Also, although details will be described later, the minor win game in this embodiment can result in a jackpot game. In the jackpot game, the open state and the closed state of the special electric accessory 65 are alternately set. One open state (which may be referred to as a "round game" and the total number of round games occurring in one jackpot may be referred to as the "number of rounds") ends based on a predetermined number (in this embodiment, 10) of game balls winning at the big winning opening 55, and the special electric accessory 65 becomes in the closed state. Further, one open state in the jackpot game also ends based on the elapse of a predetermined amount of time (in this embodiment, 30 s (seconds)) sufficient for a predetermined number of game balls to win at the big winning opening 55. On the other hand, in the minor win game, the open state of the special electric accessory 65 ends when 1.8 s has elapsed or when 10 game balls have won at the big winning opening 55. Therefore, in the minor win game, it is less likely for game balls to win at the big winning opening 55 compared to the jackpot game. In this embodiment, at the time when the jackpot game or the minor win game is started, a start demo that ends with the passage of time is set, and when the start demo ends, a round game (a minor win game in the case of a minor win) is started. At the time when all round games have ended, an end demo that ends with the passage of time is set. That is, in this embodiment, the jackpot game (including those that occur in the minor win game) is composed of a start demo, a round game, and an end demo, and the jackpot game progresses in this order.

[0039] The first starting port 57 is disposed at the lower center of the game area 50a. A first starting port sensor 70 is attached to the first starting port 57. Based on the detection result of the first starting port sensor 70, winning at the first starting port 57 is determined, and a number (in this embodiment, 4) of prize balls corresponding to the first starting port 57 are awarded. In at least a part of the case where winning at the first starting port 57 is determined, the symbol variation according to Special Figure 1 is performed. Note that, in the game area 50a according to this embodiment, obstacles such as game nails are arranged so that more game balls roll toward the first starting port 57 when rolling from the first flow path X than when rolling from the second flow path Y.

[0040] The second starting port 59 is disposed at the lower right of the game area 50a. A second starting port sensor 71 is attached to the second starting port 59. Based on the detection result of the second starting port sensor 71, winning at the second starting port 59 is determined, and a number (in this embodiment, 1) of prize balls corresponding to the second starting port 59 are awarded. In at least a part of the case where winning at the second starting port 59 is determined, the symbol variation according to Special Figure 2 is performed. Note that, in the game area 50a according to this embodiment, obstacles such as game nails are arranged so that more game balls roll toward the second starting port 59 when rolling from the second flow path Y than when rolling from the first flow path X.

[0041] An ordinary electric accessory 61 is disposed in the flow path connected to the second starting port 59. The ordinary electric accessory 61 is a member that can be switched between an open state where it is easy for a game ball to enter the second starting port 59 and a closed state where it is difficult for a game ball to enter, and is switched to either the open state or the closed state by an ordinary electric accessory solenoid 62. More specifically, the ordinary electric accessory 61 becomes open when the result of the general drawing win / loss determination described later is a win in the general drawing (hereinafter, may be simply expressed as "win in the general drawing"), and accordingly, winning in the second start port 59 is permitted. Thus, when the ordinary electric accessory 61 is in the open state, winning in the second start port 59 becomes possible, so that while suppressing the decrease of game balls by prize balls, the opportunity to execute the symbol variation according to Special Figure 2 can be significantly increased.

[0042] The gate 63 is disposed at the right center of the game area 50a. A gate sensor 74 is attached to the gate 63, and winning in the gate 63 is determined based on the detection result of the gate sensor 74. In at least a part of the case where winning in the gate 63 is determined, the symbol variation of the general drawing is performed.

[0043] The general winning port 67 is disposed at the lower left of the game area 50a. A general winning port sensor 73 is attached to the general winning port 67, and winning in the general winning port 67 is determined based on the detection result of the general winning port sensor 73, and the number (4 in this embodiment) of prize balls associated with the general winning port 67 is awarded. In this embodiment, compared with the case of rolling from the second flow path Y, the obstacles are arranged so that more game balls roll toward the general winning port 67 when rolling from the first flow path X, but the obstacles may be arranged so that more game balls roll toward the general winning port 67 when rolling from the second flow path Y. Also, a plurality of general winning ports 67 may be provided.

[0044] The out port 69 is disposed at the lowermost part of the game area 50a. The game balls that are driven into the game area 50a and do not enter the above-described respective winning ports fall into the out port 69 and are processed as out balls. In this embodiment, an out ball sensor 75 (not shown) for detecting out balls, which are game balls that have entered the above-described winning ports and the out port 69, is provided.

[0045] In addition to the sensors described above, the game board 50 is provided with a magnetic detection sensor for detecting magnetism and a radio wave detection sensor for detecting radio waves (both not shown) in order to prevent illegal acts of receiving prize balls illegally.

[0046] On the back surface of the game board 50, as shown in FIG. 5, there are mounted a main control board case 109 storing the main control board 100, a first sub-control board case 209 storing the first sub-control board 200, a second sub-control board case 309 storing the second sub-control board 300, a power control board case 509 storing the power control board 500, and a payout control board case 409 storing the payout control board 400. In addition to the back surfaces of the first sub-control board case 209 and the second sub-control board case 309, an opening / closing cover 45 that covers a part of the back surface of the main control board case 109 is detachably mounted. Note that the main control board 100 is provided with a RAM clear switch 43. In addition, the board cases and covers that cover each board are made of transparent members, and the corresponding boards are visible through each case and cover.

[0047] Also, on the back surface of the game board 50, above the opening / closing cover 45, there is arranged a game ball tank 46 in which game balls supplied from the ball supply facility of the game island are stored. The game ball tank 46 is further connected to a payout passage 49 that leads to the upper ball receiving tray 27 via a tank rail 47 and a payout unit 48. The balls paid out by the payout unit 48 are paid out to the upper ball receiving tray 27 through the payout passage 49.

[0048] So far, the structure of the gaming machine 10 in this embodiment has been described, but these are just one specific example, and the present invention can also be implemented with a different configuration.

[0049] <Regarding the control configuration of the gaming machine 10> Next, the control configuration included in the gaming machine 10 according to the present embodiment will be described with reference to FIG. 6. FIG. 6 is a block diagram showing the control configuration included in the gaming machine 10. Note that the control configuration shown in FIG. 6 is necessary for explaining the gaming machine 10 of the present embodiment, and the gaming machine 10 may include a control configuration not shown in FIG. 6.

[0050] The main control board 100 includes a CPU 101 that performs various arithmetic processes related to the game, a ROM 102 that stores data such as control programs and various lottery tables, a RAM 103 that functions as a work area and buffer memory serving as a temporary storage area, an I / O port 104 that inputs and outputs signals between peripheral boards and each device, and a random number circuit 105 that operates in a system separate from the program processing by the CPU 101 to generate a random number (hard random number). These are mutually connected via an internal bus.

[0051] The CPU 101 reads out various control programs stored in the ROM 102 and performs arithmetic processes, thereby executing various processes related to the main control of the game. The RAM 103 is backed up by the backup power supply generated in the backup power supply circuit described later. Specifically, among the information stored in the RAM 103, various information that enables the gaming machine 10 to return to the state just before the power failure using that data at the time of power restoration (when the power is turned on) after the power failure occurs is configured to be backed up. For example, in addition to the data such as the stack pointer and each register held at the time of power failure, information related to the game such as the state of the gaming machine 10 at that time (game stop state or playable state), the current general drawing lottery state, etc. is targeted for backup. Note that these pieces of information are cleared (initialized) by the RAM clear process described later. Therefore, after the RAM is cleared, the special drawing variation pattern derivation state PA (general drawing low probability described later) described later is newly set. Furthermore, when the RAM clear process is executed, the symbol sequence related to the decorative symbol becomes in the state where the initial symbol combination is stopped and displayed, and also becomes in the state where the initial symbol combination is stopped and displayed when the RAM clear process is not executed at the time of power-on and the symbol variation was not being executed at the time of the immediately preceding power failure. Also, this initial symbol combination is stopped and displayed only at the time of power-on and is not stopped and displayed by the execution of symbol variation.

[0052] In the present embodiment, at least in addition to the area where such information related to the game is stored (which may be referred to as the area related to the game of the RAM 103), the area where the complement of the checksum and the backup flag related to the area related to the game of the RAM 103 are stored (which may be referred to as the backup information area related to the game of the RAM 103) is backed up. Then, at the time of power restoration, the gaming machine 10 returns using the various information stored in the backed-up area related to the game of the RAM 103 and the backup information area related to the game of the RAM 103. Note that there is no restriction on the specific method of backup in this embodiment. For example, the area to be backed up in the RAM 103 may be realized by a configuration that can retain data non-volatilely even in the power-off state. As another example, among the RAM 103, different hardware may be provided for a first memory configured to retain data non-volatilely even in the power-off state and a second memory referred to when the gaming machine 10 operates. In that case, the gaming machine 10 may back up the information to be backed up from the second memory to the first memory at power-off, and recover the backed-up information from the first memory to the second memory at power-on.

[0053] In addition, the main control board 100 is electrically connected to the first start port sensor 70, the second start port sensor 71, the big winning port sensor 72, the general winning port sensor 73, the gate sensor 74, the out ball sensor 75, the middle frame opening sensor 76, the front frame opening sensor 77, etc., and is configured to be able to input detection signals from these sensors to the CPU 101 via the I / O port 104. Although not shown in the figure, in addition to these sensors, the main control board 100 is also electrically connected to a full detection sensor, a magnetic detection sensor, and a radio wave detection sensor, and is configured to be able to input detection signals from these sensors to the CPU 101 via the I / O port 104.

[0054] In addition, the main control board 100 is electrically connected to the first special symbol display device 91, the second special symbol display device 92, the normal symbol display device 93, the first special symbol hold lamp 94, the second special symbol hold lamp 95, the normal symbol hold lamp 96, the normal electric accessory solenoid 62, and the special electric accessory solenoid 66, and is configured to be able to control these via the I / O port 104. Similarly, the main control board 100 is electrically connected to the main operation unit 39 and the RAM clear switch 43, and is configured to be able to detect the operation of the main operation unit 39.

[0055] The main control board 100 and the first sub-control board 200 are connected by eight parallel signal lines and one strobe line, and are communicably connected only in a single direction from the main control board 100 to the first sub-control board 200. Various effect control commands are transmitted from the main control board 100 to the first sub-control board 200. Note that data cannot be transmitted from the first sub-control board 200 to the main control board 100, and the first sub-control board 200 is configured so that it cannot request data transmission to the main control board 100. Also, in this embodiment, a parallel transmission method is adopted for data transmission from the main control board 100 to the first sub-control board 200, but a serial transmission method may be adopted.

[0056] The first sub-control board 200 includes a CPU 201 that performs various arithmetic processes related to game effects based on the effect control commands from the main control board 100, a ROM 202 that stores data such as an effect control program and various lottery tables, a RAM 203 that functions as a work area and a buffer memory as a temporary storage area, and an I / O port 204 that inputs and outputs signals between the peripheral board and each device. These are interconnected via an internal bus, and the CPU 201 is configured to execute main control related to game effects according to the control program stored in the ROM 202. Note that the first sub-control board 200 is electrically connected to the effect button 37 and the cursor button 38, and is configured to be able to detect operations of the operation unit.

[0057] Also, the first sub-control board 200 generates an image control command for instructing an image to be displayed on the second sub-control board 300, an audio control command for instructing an audio to be output to the audio control board 310, lamp control data for controlling the lighting of various lamps such as the frame lamp 35, and movable control data for controlling the movement of the sub-display unit 82, etc. in the effect control process based on the effect control commands from the main control board 100. Here, the first sub-control board 200 is connected to the second sub-control board 300 and the audio control board 310 so as to enable bidirectional communication. While each control command (image control command, audio control command) is transmitted from the first sub-control board 200 to the second sub-control board 300 or the audio control board 310, as a response thereto, a response command (ACK command) indicating that the control command has been normally received is transmitted from each control board (the second sub-control board 300, the audio control board 310) to the first sub-control board 200.

[0058] Also, the first sub-control board 200 is electrically connected to the frame lamp 35 and the movable decorative body 22, and transmits lamp control data via the I / O port 204. The frame lamp 35 and the movable decorative body 22 are configured such that their lighting is controlled by the lamp control data transmitted from the first sub-control board 200. Furthermore, the first sub-control board 200 is electrically connected to the movable decorative body 22 and the sub-display unit 82, and transmits movable control data via the I / O port 204. The movable decorative body 22 and the sub-display unit 82 are configured such that their movement is controlled by the movable control data transmitted from the first sub-control board 200.

[0059] Although not shown in the drawings, the second sub-control board 300 includes a CPU that performs various arithmetic processes related to image rendering based on an image control command from the first sub-control board 200, a ROM that stores an image control program, various data, etc., a RAM that functions as a work area and a buffer memory serving as a temporary storage area, and an I / O port that inputs and outputs signals between the peripheral board and each device. The CPU is configured to execute main control related to image rendering according to the control program stored in the ROM. Furthermore, the second sub-control board 300 is equipped with a VDP that generates image data in accordance with the content of the effect determined by the effect content determination means 225 described later based on the control signal received from the CPU, and a sound source IC that generates acoustic data in accordance with the content of the effect based on the control signal received from the CPU. The VDP is a so-called image processor that reads the image data stored in the image ROM in response to an instruction from the CPU, processes this image data, and transmits the generated image data to the main display unit 81 and the sub-display unit 82. Also, a high-speed VRAM used for the expansion and processing of the image data read from the image ROM is connected to this VDP.

[0060] The voice control board 310 includes a CPU 311 that performs various arithmetic processes related to voice effects based on the voice control commands from the first sub-control board 200, a ROM 312 that stores voice control programs, voice data, etc., a RAM 313 that functions as a work area and buffer memory serving as a temporary storage area, and an I / O port 314 that inputs and outputs signals between the peripheral board and each device. The CPU 311 is configured to execute the main control related to voice effects according to the control program stored in the ROM 312. Therefore, the voice control board 310 reads the voice data stored in the ROM 312 in response to the voice control commands received from the first sub-control board 200, synthesizes the read voice data, and transmits the final synthesized voice data to the speaker 33 via an amplifier, enabling the speaker 33 to emit sound.

[0061] The payout control board 400 is mainly composed of a CPU, a ROM, and a RAM (all not shown in the figure). Also, 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 commands from the main control board 100, it executes control to drive the payout unit 48 to pay out game balls, and based on the operation amount of the operation handle 31, it synchronously drives the ball feeding mechanism and the firing mechanism to control the firing of game balls.

[0062] The power control board 500 includes a normal power supply circuit 501 that generates a normal power supply to supply electronic components and electrical components such as the above-described control boards based on the primary power supply supplied from the power supply equipment of the game island, a backup power supply circuit 502 that generates a backup power supply, and a power failure detection circuit 503 that detects a power failure (the supply voltage by the normal power supply drops to a predetermined voltage drop). In addition, a power switch 40 is connected to the power control board 500. On the premise that the primary power supply is supplied from the power supply equipment of the game island, when the power switch 40 is turned on, the normal power supply circuit 501 of the power control board 500 generates a normal power supply, and the power is supplied to electronic components and electrical components including the above-described control boards (main control board 100, first sub-control board 200, second sub-control board 300, and payout control board 400). In addition, when the power failure detection circuit 503 of the power control board 500 detects a power failure, the power control board 500 transmits a power failure signal (NMI signal) to each of the main control board 100, the first sub-control board 200, and the payout control board 400. In addition, the backup power supply circuit 502 is configured to be charged when the power is supplied from the power supply equipment of the game island to the gaming machine 10. Note that the backup power supply circuit 502 may be provided on the payout control board 400, and the power failure detection circuit 503 may not be provided on the power control board 500 but may be provided on each of the main control board 100, the first sub-control board 200, and the payout control board 400.

[0063] <Regarding the functional configuration of the gaming machine 10> Next, with reference to FIG. 7, the functional configuration of the gaming machine 10 according to the present embodiment will be described. FIG. 7 is a block diagram showing the functional configuration of the gaming machine 10. Note that the functional configuration shown in FIG. 7 is necessary for explaining the gaming machine 10 of the present embodiment, and the gaming machine 10 may include a functional configuration not shown in FIG. 7. In addition, when explaining the functional configuration, FIGS. 8 and 9 will be referred to as necessary.

[0064] As shown in FIG. 7, the main control board 100 includes a ball entry determination means 110, a main random number generation means 115, a main hold control means 120, a preliminary determination means 125, a special drawing selection means 130, a general drawing selection means 135, a big win game control means 140, a symbol display control means 145, an electric accessory control means 150, a game state control means 155, a main information storage means 160, a main error control means 165, a main command management means 170, a power restoration process execution means 175, and a power-off process execution means 180. These means functionally represent what is realized by each control configuration on the main control board 100 described with reference to FIG. 6.

[0065] First, the main information storage means 160 is a means for temporarily storing data read by the means provided in the main control board 100, data derived by calculations in the means, etc. in corresponding storage areas. In particular, the data (production control command) stored in the transmission command storage area of the main information storage means 160 is transmitted to the sub-command management means 270 of the first sub-control board 200 described later by the command transmission means after being stored.

[0066] The ball entry determination means 110 determines the winning at each winning port based on the detection results of the sensors provided at each winning port. In addition, when the ball entry determination means 110 determines the winning of a game ball by a sensor provided at a winning port such as the big winning port sensor 72, it generates a production control command (winning command) including information capable of specifying the type of the sensor related to the winning, and stores the command in the transmission command storage area of the main information storage means 160.

[0067] The main random number generation means 115 can generate a plurality of types of random numbers with different update ranges by the random number circuit 105, and acquires (latches) one or more random numbers corresponding to the winning port from the random number circuit 105 at the timing when the winning at the winning port is determined. More specifically, when a winning at the first start port 57 or the second start port 59 is determined, the main random number generation means 115 acquires the random numbers for special drawing win / loss determination, the random numbers for special drawing stop symbol lottery, and the random numbers for special drawing variation pattern lottery, which will be described later. When a winning at the gate 63 is determined, the random numbers for general drawing win / loss determination, the random numbers for general drawing stop symbol lottery, and the random numbers for general drawing variation pattern lottery, which will be described later, are stored in the corresponding storage areas of the main information storage means 160. Note that the random number circuit 105 monitors whether a plurality of types of random numbers updated by itself are updated normally. When an update abnormality occurs where the random numbers are not updated normally, information indicating that the abnormality has occurred is written into a specific storage area of the random number circuit 105. Therefore, the CPU 101 can grasp that an update abnormality has occurred in the random number circuit 105.

[0068] The main hold control means 120 performs control regarding the hold of symbol variation related to the special drawing and the hold of symbol variation related to the general drawing. Regarding the special drawing 1, the random numbers for special drawing win / loss determination, the random numbers for special drawing stop symbol lottery, and the random numbers for special drawing variation pattern lottery, which are acquired triggered by a winning at the first start port 57, are held (stored) as the operation hold information of the special drawing 1. More specifically, the main hold control means 120 is provided with a hold counter (hereinafter referred to as the "special drawing 1 hold counter") that is incremented by 1 each time the operation hold information of the special drawing 1 is held and decremented by 1 each time the operation hold information of the special drawing 1 is used (used in the lottery by the special drawing lottery means 130). Until the value of the special drawing 1 hold counter reaches the upper limit value (in this embodiment, 4), the operation hold information is stored in the storage area corresponding to the current special drawing 1 hold counter of the main information storage means 160. Each time the operation hold information is used, the used operation hold information is cleared, and the remaining operation hold information is moved (shifted) in order from the smaller special drawing 1 hold counter to the storage area corresponding to the special drawing 1 hold counter that is 1 less than the current special drawing 1 hold counter from the current storage area. Further, the main hold control means 120 also performs the same control as described above separately from FIG. 1 with respect to FIG. 2 of the special drawings and the general drawings. The hold counter in FIG. 2 of the special drawings is referred to as the FIG. 2 hold counter of the special drawings, and the upper limit value of the value of the FIG. 2 hold counter of the special drawings in the present embodiment is 4. Further, in the following description, "holding of operation hold information" may be expressed as "holding of symbol variation" or simply "holding". In addition, when the main hold control means 120 updates (adds or subtracts) the operation hold information (hold counter) of FIG. 1 or FIG. 2 of the special drawings, it generates an effect control command (hold command) including the FIG. 1 hold counter and the FIG. 2 hold counter of the special drawings, and stores the command in the transmission command storage area of the main information storage means 160. In the present embodiment, when both the operation hold information corresponding to FIG. 1 and the operation hold information corresponding to FIG. 2 are held, a priority variation is performed in which the operation hold information corresponding to FIG. 2 is preferentially used. However, instead of this priority variation, a winning order variation in which the operation hold information is used in the order in which it was held regardless of whether it corresponds to FIG. 1 or FIG. 2, or a simultaneous variation in which the operation hold information corresponding to FIG. 1 and the operation hold information corresponding to FIG. 2 are used simultaneously when both the operation hold information corresponding to FIG. 1 and the operation hold information corresponding to FIG. 2 are held may be adopted.

[0069] The pre-determination means 125 executes a pre-determination for a preview effect for at least a part of the case where the operation hold information of the special drawing is held at a predetermined pre-determination timing. More specifically, the pre-determination means 125 reads out each random number of the operation hold information held this time, and executes a pre-determination for each of the special drawing validity determination, the special drawing stop symbol lottery, and the special drawing variation pattern lottery, which will be described later. In each pre-determination, a lottery table (not shown) that is the same as or equivalent to the lottery table used for the lottery corresponding to each pre-determination is used. Therefore, the results of these pre-determinations are the same as the results of the lottery to be executed later. In addition, the preliminary determination means 125 generates a presentation control command (preliminary determination command) including the result of the derived preliminary determination, and stores the command in the transmission command storage area of the main information storage means 160. Since the preliminary determination command is transmitted (generated and stored in the transmission command storage area of the main information storage means 160) at least in part at a predetermined preliminary determination timing, it will be transmitted following the above-described held command. Here, the predetermined preliminary determination timing includes, for example, the timing when the operation hold information of the special figure is held. In this embodiment, when the operation hold information of special figure 1 is held during the low-probability general figure described later, the preliminary determination is restricted, and thus the transmission of the preliminary determination command corresponding to the preliminary determination is also restricted. On the other hand, regarding the case where the operation hold information of special figure 2 is held during the high-probability general figure described later, the preliminary determination may or may not be restricted.

[0070] The special figure lottery means 130 includes a special figure validity determination means 131, a special figure stop symbol lottery means 132, and a special figure variation pattern derivation means 133, and executes the processing by each means in the order of the special figure validity determination means 131, the special figure stop symbol lottery means 132, and the special figure variation pattern derivation means 133. When the variation start condition of the special figure is satisfied, the special figure lottery means 130 reads out the earliest operation hold information among the operation hold information held in the main information storage means 160. Note that "the variation start condition of the special figure is satisfied" means, as an example, that it is not during a big win game, that neither special figure 1 nor special figure 2 is in the middle of executing a symbol variation (including during the stop display of the symbol variation related to special figure 1 or special figure 2), and that all conditions for the existence of operation hold information in at least one of special figure 1 and special figure 2 are satisfied.

[0071] Here, FIGS. 8 and 9 are diagrams schematically showing the lottery tables used in the main control board 100, and will be referred to as necessary in the following description. In addition, in the lottery using the lottery table, including those other than these lottery tables, for the read random numbers, the lottery values stored in the lottery table are sequentially added in a predetermined order (if there is only one target lottery value, the number of additions is one), and the result corresponding to the lottery value with a carry (digit overflow) generated is derived as the result of the lottery. Similarly, in the description of the lottery table, for convenience of explanation, the lottery table is named, but it is only necessary that the data such as the lottery values included in the lottery table corresponding to the name are stored in each ROM in an identifiable manner, and these names do not specify the area where the data is stored. In the illustrated lottery table, if there are items described for convenience of explanation and "-" or "0" is described as a lottery value, these do not necessarily indicate the data stored in each ROM. And winning the result with "-" or "0" described as the lottery value does not occur. Further, if the same lottery value as the random number range used in the lottery (the number of random numbers that can be obtained within the range) is described in the lottery table, since the result is derived 100%, it is not necessarily necessary to conduct the lottery. Also, if the total value of the lottery values used in one lottery matches the random number range used in the lottery, a carry will always occur in the addition of the last lottery value, so it is not necessary to perform the addition, and in that case, the lottery value itself used for the addition is also unnecessary.

[0072] For each symbol variation, the special figure win / loss determination means 131 reads a random number for special figure win / loss determination and executes a special figure win / loss determination to determine whether to win a big win, a small win, or a loss by lottery using the read random number and the lottery table for special figure win / loss determination. Fig. 8(a) is a diagram schematically showing a lottery table for determining the validity of a special drawing. The lottery table is different between Special Drawing 1 and Special Drawing 2, and the range of random numbers used in these determinations is 0 to 65,535. Therefore, in the determination of the validity of Special Drawing 1, a big win is derived with a probability of 205 / 65,536 (about 1 / 320), and it is a loss otherwise, and a small win is not derived. On the other hand, in the determination of the validity of Special Drawing 2, a big win is derived with a probability of 205 / 65,536 (about 1 / 320), a small win is derived with a probability of 1820 / 65,536 (about 1 / 36.0), and it is a loss otherwise. In addition, in the present embodiment, as will be described later, since a big win game can occur via a small win, the probability of deriving a big win in the determination of the validity of the special drawing is set as the one probability described above.

[0073] When the result of the determination of the validity of the special drawing is a big win or a small win, the special drawing stop symbol lottery means 132 determines the stop symbol of the special drawing by lottery using a random number for special drawing stop symbol lottery (in this embodiment, in the range of 0 to 999) and a lottery table for special drawing stop symbol lottery. Specifically, as shown in Fig. 8(b), which is a diagram schematically showing the lottery table for stop symbol lottery used when a big win is derived in the determination of the validity of Special Drawing 1, when a big win is derived in the determination of the validity of Special Drawing 1, symbol A is determined as the stop symbol with a probability of 100 / 1000 (1 / 10), and symbol B is determined as the stop symbol with a probability of 900 / 1000 (about 1 / 1.11). Here, regardless of whether symbol A or symbol B is determined, after the end of the big win game corresponding to these stop symbols, the general drawing high probability described later is achieved. However, the number of symbol variations during which the general drawing high probability continues (hereinafter referred to as "the specified number of times related to the general drawing high probability") is 80 times after the end of the big win game when symbol A is determined, and 40 times after the end of the big win game when symbol B is determined. Also, the number of rounds of the big win game corresponding to symbol A is 10, while the number of rounds of the big win game corresponding to symbol B is 4. Therefore, it can be said that symbol A is more advantageous than symbol B from both viewpoints of the number of rounds and the specified number of times related to the general drawing high probability.

[0074] FIG. 8(c) is a diagram schematically showing a lottery table for stopping symbol lottery used when a small win is derived in the special figure validity determination according to Special FIG. 2. As shown in FIG. 8(c), when a small win is derived in the special figure validity determination according to Special FIG. 2, symbol a is determined as the stopping symbol with a probability of 500 / 1000 (1 / 2), symbol b is determined as the stopping symbol with a probability of 300 / 1000 (about 1 / 3.33), and symbol c is determined as the stopping symbol with a probability of 200 / 1000 (1 / 5). Here, for symbol a, the number of rounds of the jackpot game that occurs in the small win game related to the symbol is 10, and it is a stopping symbol that becomes a high probability of general figure after the end of the jackpot game. The specified number of times related to the high probability of general figure is 80 times. For symbol b, the number of rounds of the jackpot game that occurs in the small win game related to the stopping symbol is 4, and it is a stopping symbol that becomes a high probability of general figure after the end of the jackpot game. The specified number of times related to the high probability of general figure is 40 times. Also, for symbol c, the number of rounds of the jackpot game that occurs in the small win game related to the stopping symbol is 10, and it is a stopping symbol that becomes a low probability of general figure (no high probability of general figure is set) after the end of the jackpot game. Therefore, it can be said that symbol a is more advantageous than symbol b from both viewpoints of the number of rounds and the specified number of times related to the high probability of general figure. Furthermore, it can be said that symbol a is more advantageous than symbol c from the viewpoint of the specified number of times related to the high probability of general figure, and it can be said that symbol a has the same degree of advantage as symbol c from the viewpoint of the number of rounds. Since symbol c is a symbol that becomes a low probability of general figure after the end, it can be said that symbol c is more disadvantageous than symbol b. Also, the number of rounds in the jackpot game when a jackpot game occurs in the small win game is the number calculated with one round of the small win game. Furthermore, in the following description, the jackpot game that occurs in the small win game related to symbol a may be expressed as "the jackpot game related to symbol a", the jackpot game that occurs in the small win game related to symbol b may be expressed as "the jackpot game related to symbol b", and the jackpot game that occurs in the small win game related to symbol c may be expressed as "the jackpot game related to symbol c".

[0075] FIG. 8(d) is a diagram schematically showing a lottery table for stopping symbol lottery used when a jackpot is derived in the special figure win / loss determination according to Special Figure 2. As shown in FIG. 8(d), when a jackpot is derived in the special figure win / loss determination according to Special Figure 2, symbol d is determined as the stopping symbol with a probability of 1000 / 1000 (1 / 1). In particular, symbol d is a stopping symbol that corresponds to a jackpot game with 10 rounds and becomes a high-probability common figure after the end of the jackpot game, and the specified number of times related to the high-probability common figure is 80 times, which is the same as the jackpot game related to symbol a.

[0076] Further, when the result of the special figure win / loss determination according to Special Figure 1 is a miss, the special figure stopping symbol lottery means 132 determines symbol C as the stopping symbol, and when the result of the special figure win / loss determination according to Special Figure 2 is a miss, it determines symbol e as the stopping symbol (both are not shown).

[0077] Thus, in the above-described present embodiment, the jackpot game generated in the symbol variation according to Special Figure 2 tends to have a higher degree of advantage than the jackpot game generated in the symbol variation according to Special Figure 1. Therefore, the game interest can be further enhanced by the transition from the special figure variation pattern derivation state PA (described later) to another special figure variation pattern derivation state (special figure variation pattern derivation state PB or special figure variation pattern derivation state PC described later).

[0078] The special figure variation pattern derivation means 133 has a plurality of types of special figure variation pattern lottery tables to be referred to when determining the special figure variation pattern. Based on the current special figure variation pattern derivation state and the result of the current special figure win / loss determination, one special figure variation pattern lottery table for determining the current special figure variation pattern is selected, and one special figure variation pattern is determined using the selected special figure variation pattern lottery table and a random number for special figure variation pattern lottery, and the variation time is determined based on the determined special figure variation pattern. Here, the variation time refers to the time from the start of the symbol variation related to the special figure (Special Figure 1 or Special Figure 2) to the end of the symbol variation. Details of the transition conditions and the like will be described later. In the special drawing variation pattern derivation state in this embodiment, there are a special drawing variation pattern derivation state PA, a special drawing variation pattern derivation state PB, and a special drawing variation pattern derivation state PC. And, the above-described method for determining the special drawing variation pattern is adopted for the symbol variation related to the special drawing 1 in the special drawing variation pattern derivation state PA, and for the symbol variation related to the special drawing 2 in the special drawing variation pattern derivation state PB and the special drawing variation pattern derivation state PC. On the other hand, in the symbol variation related to the other special drawing (the special drawing for which the above-described method for determining the special drawing variation pattern is adopted) in each special drawing variation pattern derivation state, one special drawing variation pattern determined in advance according to the result of the special drawing validity determination is determined. In particular, in this embodiment, in the symbol variation related to the special drawing 2 in the special drawing variation pattern derivation state PA, when the result of the special drawing validity determination related to the symbol variation is a miss, and when the result of the special drawing validity determination related to the symbol variation is a big win, a variation pattern with a variation time of 1000 ms is determined. In the symbol variation related to the special drawing 1 in the special drawing variation pattern derivation state PB or the special drawing variation pattern derivation state PC, when the result of the special drawing validity determination related to the symbol variation is a miss, and when the result of the special drawing validity determination related to the symbol variation is a big win, a variation pattern with a variation time of 2000 ms is determined. When the result of the special drawing validity determination of the symbol variation is a miss, a variation pattern with a variation time of 2000 ms is determined (the same applies to the case of a small win).

[0079] FIG. 9(a) is a diagram schematically showing a special drawing variation pattern lottery table used for the symbol variation related to the special drawing 1 in the special drawing variation pattern derivation state PA, and the range of the random number used in the lottery is 0 to 999. As shown in FIG. 9(a), in the symbol variation related to the special drawing 1 in the special drawing variation pattern derivation state PA, the special drawing variation pattern HNP to the special drawing variation pattern ASP-C can be determined. Specifically, when the result of the special figure pass / fail determination is a miss in the symbol variation related to special figure 1 in the special figure variation pattern derivation state PA, the special figure variation pattern HNP is determined with a probability of 900 / 1000 (about 1 / 1.11), the special figure variation pattern HRP is determined with a probability of 52 / 1000 (about 1 / 19.2), the special figure variation pattern HSP1-A is determined with a probability of 13 / 1000 (about 1 / 76.9), the special figure variation pattern HSP1-B is determined with a probability of 11 / 1000 (about 1 / 90.9), the special figure variation pattern HSP2-A is determined with a probability of 9 / 1000 (about 1 / 111), the special figure variation pattern HSP2-B is determined with a probability of 7 / 1000 (about 1 / 143), the special figure variation pattern HSP3-A is determined with a probability of 5 / 1000 (1 / 200), and the special figure variation pattern HSP3-B is determined with a probability of 3 / 1000 (about 1 / 333). In this case, the special figure variation patterns ASP1-A to ASP-C are not determined. Note that the details will be described later with reference to FIG. 9(b). When the special figure variation pattern HNP is determined, the special figure variation pattern is further specified using the value of the special figure 1 hold counter at the start of the current symbol variation. On the other hand, when the result of the special figure pass / fail determination is a big win in the symbol variation related to special figure 1 in the special figure variation pattern derivation state PA, the special figure variation pattern ASP1-A is determined with a probability of 90 / 1000 (about 1 / 11.1), the special figure variation pattern ASP1-B is determined with a probability of 110 / 1000 (about 1 / 9.09), the special figure variation pattern ASP2-A is determined with a probability of 135 / 1000 (about 1 / 7.41), the special figure variation pattern ASP2-B is determined with a probability of 165 / 1000 (about 1 / 6.06), the special figure variation pattern ASP3-A is determined with a probability of 180 / 1000 (about 1 / 5.56), the special figure variation pattern ASP3-B is determined with a probability of 220 / 1000 (about 1 / 4.56), and the special figure variation pattern ASP-C is determined with a probability of 100 / 1000 (1 / 10). In this case, the special figure variation patterns HNP to HSP3-B are not determined. Thus, in this embodiment, when the result of the special drawing validity determination fails in the symbol variation related to Special Drawing 1 in the special drawing variation pattern derivation state PA, any one of the special drawing variation patterns HRP to HSP3-B is determined at a rate of 100 / 1000 (1 / 10), and the special drawing variation pattern HNP is determined at a rate of 900 / 1000 (about 1 / 1.11). Further, when the result of the special drawing validity determination is a big win in the symbol variation related to Special Drawing 1 in the special drawing variation pattern derivation state PA, any one of the special drawing variation patterns ASP1-A to ASP-C is determined at a rate of 1000 / 1000 (1 / 1). Here, in the description of the special drawing variation pattern of this embodiment, when two special drawing variation patterns are described with "~" in between, the description of the special drawing variation patterns existing between the special drawing variation pattern described earlier and the special drawing variation pattern described later shall be omitted in accordance with the order described in the drawing related to the special drawing variation pattern lottery table for each special drawing variation pattern derivation state. Also, in the description of the special drawing variation pattern of this embodiment, regardless of whether there is a description of the corresponding variation time, if the names of the special drawing variation patterns are different, it means that the different special drawing variation patterns are different.

[0080] FIG. 9(b) is a diagram schematically showing a special drawing variation pattern lottery table used when the special drawing variation pattern HNP is determined in the symbol variation related to Special Drawing 1 in the special drawing variation pattern derivation state PA. The range of the random number used in this lottery (different from the random number used in the lottery related to the special drawing variation pattern lottery table shown in FIG. 9(a)) is 0 to 999. As shown in FIG. 9(b), the special drawing variation pattern HNP that can be determined in the symbol variation related to Special Drawing 1 in the special drawing variation pattern derivation state PA includes the special drawing variation pattern HNP-A with a variation time of 3200 ms (milliseconds), the special drawing variation pattern HNP-B with a variation time of 5600 ms, the special drawing variation pattern HNP-C with a variation time of 8000 ms, and the special drawing variation pattern HNP-D with a variation time of 11200 ms. In this order, the variation time becomes longer. Specifically, when the special drawing 1 hold counter at the start of the current symbol variation is 3, the special drawing variation pattern HNP-A is determined with a probability of 1000 / 1000 (1 / 1). Similarly, when the special drawing 1 hold counter at the start of the current symbol variation is 2, the special drawing variation pattern HNP-A is determined with a probability of 150 / 1000 (about 1 / 6.67), and the special drawing variation pattern HNP-B is determined with a probability of 850 / 1000 (about 1 / 1.18). When the special drawing 1 hold counter at the start of the current symbol variation is 1, the special drawing variation pattern HNP-A is determined with a probability of 50 / 1000 (1 / 20), the special drawing variation pattern HNP-B is determined with a probability of 150 / 1000 (about 1 / 6.67), and the special drawing variation pattern HNP-C is determined with a probability of 800 / 1000 (1 / 1.25). When the special drawing 1 hold counter at the start of the current symbol variation is 0, the special drawing variation pattern HNP-B is determined with a probability of 50 / 1000 (1 / 20), the special drawing variation pattern HNP-C is determined with a probability of 100 / 1000 (1 / 10), and the special drawing variation pattern HNP-D is determined with a probability of 850 / 1000 (about 1 / 1.18). In the following description, when the value of the special drawing hold counter to be referred to is 3, it may be referred to as "hold 3", when the value of the special drawing hold counter is 2, it may be referred to as "hold 2", when the value of the special drawing hold counter is 1, it may be referred to as "hold 1", and when the value of the special drawing hold counter is 0, it may be referred to as "hold 0". Thus, when the special drawing variation pattern HNP is determined in the special drawing variation pattern derivation state PA, the special drawing variation pattern (variation time) that is likely to be determined depends on the value of the special drawing 1 hold counter at the start of the current symbol variation. More specifically, the smaller the value of the special drawing 1 hold counter at the start of the current symbol variation, the more likely it is that a special drawing variation pattern with a longer variation time will be determined (the larger the value of the special drawing 1 hold counter at the start of the current symbol variation, the more likely it is that a shorter variation time will be determined). In addition, such a special drawing variation pattern HNP (hereinafter sometimes referred to as the "basic special drawing variation pattern") also exists in the special drawing variation pattern derivation states PB and PC. In these special drawing variation pattern derivation states, unlike the special drawing variation pattern derivation state PA, the hold counter to be referred to is such that the value of the special drawing 2 hold counter is referred to in each case.

[0081] In addition, at the start of the symbol variation, the special drawing variation pattern derivation means 133 generates a production control command (variation start command) including the stop symbol of the special drawing determined as a result of the special drawing validity determination and the determined special drawing variation pattern, and stores the command in the transmission command storage area of the main information storage means 160.

[0082] Similar to the special drawing lottery means 130, when the general drawing is not in the process of symbol variation, the general drawing lottery means 135 reads out the earliest operation hold information among the operation hold information held in the main information storage means 160, executes a general drawing validity determination for determining the validity of the general drawing using the read random number, and determines various parameters related to the general drawing (general drawing variation time, general drawing stop display time, etc.) based on the result of the general drawing validity determination and information such as the current special drawing variation pattern derivation state. In the general drawing validity determination, there are a state where the general drawing lottery state is a high-probability state (sometimes abbreviated as "general drawing high probability") and a state where the general drawing lottery state is a low-probability state (sometimes abbreviated as "general drawing low probability"). Although the illustration of the lottery table is omitted, in this embodiment, in the general drawing high probability, the general drawing wins with a probability of 65535 / 65536 and loses with a probability of the remaining 1 / 65536. On the other hand, in the general drawing low probability, the general drawing wins with a probability of 1 / 65536 and loses with a probability of the remaining 65535 / 65536. Note that in the general drawing low probability, it may be set so that the general drawing does not win (loses with a probability of 65536 / 65536).

[0083] When starting a jackpot game, the jackpot game control means 140 generates an effect control command (start demo command) including information related to the jackpot game (required time for the start demo, number of rounds, and subsequent special figure variation pattern derivation state), and stores it in the transmission command storage area of the main information storage means 160. When the start demo ends, the effect control command (round start command) is generated and stored in the transmission command storage area of the main information storage means 160. Further, when the round game ends, an effect control command (end demo command) including the required time for the end demo of the jackpot game is generated and stored in the transmission command storage area of the main information storage means 160. Furthermore, these commands are the same even in a jackpot game triggered by a minor win game. Specifically, when starting a minor win game, the jackpot game control means 140 generates a start demo command and stores it in the transmission command storage area of the main information storage means 160. When the start demo ends, a round start command is generated and stored in the transmission command storage area of the main information storage means 160, and an end demo command is generated and stored in the transmission command storage area of the main information storage means 160.

[0084] Also, when the result of the special figure win / loss determination is a minor win, the jackpot game control means 140 starts a minor win game. When a game ball passes through the V winning area (not shown) provided in the big winning opening 55 during the minor win game, after the end of the minor win game, a jackpot game corresponding to the minor win can be started. Therefore, in this embodiment, the minor win game functions as a game that triggers a jackpot game. If the game ball does not pass through the V winning area during the minor win game, the jackpot game is not started after the end of the minor win game.

[0085] The symbol display control means 145 causes the first special symbol display device 91 to variably display the first special symbol in accordance with the variation time corresponding to the determined special symbol variation pattern of the first special symbol, and causes the first special symbol to be stopped and displayed with the stop symbol determined by the special symbol stop symbol lottery after the elapse of the variation time. Similarly, in accordance with the variation time corresponding to the determined special symbol variation pattern of the second special symbol, the second special symbol is variably displayed on the second special symbol display device 92, and after the elapse of the variation time, the second special symbol is stopped and displayed with the stop symbol determined by the special symbol stop symbol lottery. Here, the stop display time (interval) of the symbol variation related to the special symbol refers to the time from when the special symbol is stopped and displayed until the symbol variation of the next special symbol can be started (when the result of the special symbol win / loss determination is a loss), or the time from when the symbol variation of the special symbol ends until the big win game or small win game is started (when the result of the general symbol win / loss determination is a win for the general symbol). The stop display time of the symbol variation related to the special symbol in the present embodiment is uniformly 300 ms regardless of the type of the special symbol or the result of the special symbol win / loss determination. Further, the symbol display control means 145 has a special symbol game timer for managing the time (variation time, stop display time) related to the display of the first special symbol and the second special symbol, and when stopping and displaying the special symbol (at the timing when the value of the special symbol game timer becomes "0"), generates an effect control command (variation stop command) for requesting the definite stop display of the decorative symbol, and stores the command in the transmission command storage area of the main information storage means 160. Here, the definite stop display of the decorative symbol refers to the final stop display of the decorative symbol in the symbol variation, which is different from the temporary stop display of the decorative symbol that can occur during the execution of the symbol variation. In the temporary stop display of the decorative symbol, the stopped decorative symbol has an operation of shaking slightly up and down (so-called shaking variation), while in the definite stop display of the decorative symbol, the stopped decorative symbol does not have the shaking variation. Therefore, the player can recognize whether the stop display of the decorative symbol is a definite stop display or a temporary stop display.

[0086] Furthermore, the symbol display control means 145 causes the normal symbol to be variably displayed on the normal symbol display device 93 in accordance with the variation time corresponding to the determined normal symbol variation pattern of the normal drawing, and causes the normal symbol to be stopped and displayed with the determined stop symbol after the elapse of the variation time. Note that the symbol display control means 145 has a normal game timer for managing the time related to the normal symbol (such as the normal symbol variation time, the normal symbol stop display time, etc.).

[0087] The electric accessory control means 150 outputs a control signal to the special electric accessory solenoid 66 in the above-mentioned big win game or small win game, and causes the special electric accessory 65 to be released in accordance with the release pattern corresponding to the stop symbol of the special drawing.

[0088] The game state control means 155 controls the normal drawing lottery state. Specifically, the game state control means 155 sets the normal drawing to a low probability regardless of the stop symbol of the special drawing related to the big win game at the start of the big win game, and when the specified conditions such as the end of the big win game are satisfied, sets the normal drawing to a high probability until the specified number of symbol variations related to the high probability of the normal drawing are performed, and sets the normal drawing to a low probability when the specified number of symbol variations related to the high probability of the normal drawing are completed. Here, as will be described later, in the present embodiment, the number of times of symbol variation execution used for determining whether or not the specified number related to the high probability of the normal drawing has been reached is the number of times of symbol variation execution related to the special drawing 2, but the number of times of symbol variation execution used for the determination may be the sum of the number of times of symbol variation execution related to the special drawing 2 and the number of times of symbol variation execution related to the special drawing 1. Also, in the present embodiment, during the small win game, the normal drawing lottery state in the symbol variation in which the small win game occurs is maintained.

[0089] Such a normal drawing lottery state changes in link with the above-mentioned special drawing variation pattern derivation state, and the transition of the special drawing variation pattern derivation state is managed by the game state control means 155. Hereinafter, the transition of the special drawing variation pattern derivation state will be described with reference to FIGS. 10(a) and 10(b). Note that FIG. 10(a) is a state transition diagram showing the transition of the special drawing variation pattern derivation state, and FIG. 10(b) is a diagram showing the relationship of the average variation time for each special drawing variation pattern derivation state. As shown in Fig. 10(a), in the special drawing variation pattern derivation state, there is a special drawing variation pattern derivation state PA as a special drawing variation pattern derivation state corresponding to the general drawing low probability, and there are a special drawing variation pattern derivation state PB and a special drawing variation pattern derivation state PC as special drawing variation pattern derivation states corresponding to the general drawing high probability. Except during the jackpot game, one of these special drawing variation pattern derivation states is set. And there are transition conditions (i) to (vi) for the transition conditions between the special drawing variation pattern derivation state PA to the special drawing variation pattern derivation state PC.

[0090] Specifically, the transition condition (i) is the end of the jackpot game related to symbol B, the transition condition (ii) is the end of the jackpot game related to symbol A, the transition condition (iii) is the end of the jackpot game related to symbol a, symbol b, or symbol d, the transition condition (iv) is the end of the symbol variation when the number of symbol variations related to the special drawing 2 executed without sandwiching a jackpot game in the general drawing high probability reaches 40 times (the specified number of times related to the general drawing high probability of the special drawing variation pattern derivation state PB), the transition condition (v) is the end of the symbol variation when the number of symbol variations related to the special drawing 2 executed without sandwiching a jackpot game in the general drawing high probability reaches 80 times (the specified number of times related to the general drawing high probability of the special drawing variation pattern derivation state PC), and the transition condition (vi) is the end of the jackpot game related to symbol b. In addition, when a jackpot game related to symbol a or symbol d occurs in the special drawing variation pattern derivation state PC, after the end of the jackpot game, it will transition back to the special drawing variation pattern derivation state PC again, and the number of symbol variations related to the special drawing 2 that can be executed until the specified number of times related to the general drawing high probability of the special drawing variation pattern derivation state PC is reset. This is the same when a jackpot game related to symbol b occurs in the special drawing variation pattern derivation state PB. Also, although not shown in the figure, in the small win game that occurred in the special drawing variation pattern derivation state PB and the special drawing variation pattern derivation state PC, if the game ball did not pass through the V winning area and no jackpot game occurred, then at the end of the small win game, the current special drawing variation pattern derivation state ends and transitions to the special drawing variation pattern derivation state PA.

[0091] As shown in FIG. 10(b), the average variation time of each of the special figure variation pattern derivation state PA, the special figure variation pattern derivation state PB, and the special figure variation pattern derivation state PC becomes shorter in the order of the special figure variation pattern derivation state PA, the special figure variation pattern derivation state PB, and the special figure variation pattern derivation state PC. This is due to the length of the variation time related to the basic special figure variation pattern that is most easily determined in each special figure variation pattern derivation state. Here, the average variation time refers to the sum of the variation times obtained by multiplying each of the variation times related to the special figure variation patterns that can be selected in a certain special figure variation pattern derivation state by the appearance rate (derived by multiplying the winning probability of the special figure variation pattern by the probability of obtaining the result of the special figure win / loss determination, which is the probability that can occur in any symbol variation). However, in this embodiment, when there is only one special figure variation pattern that can be selected in a certain special figure variation pattern derivation state, the variation time related to the special figure variation pattern is treated as the average variation time.

[0092] Further, when a transition occurs in the general figure lottery state or the special figure variation pattern derivation state, the game state control means 155 generates an effect control command (game state designation command) including the state after the transition, and stores the command in the transmission command storage area of the main information storage means 160. Furthermore, in each special figure variation pattern derivation state, the game state control means 155 counts the number of executions of the symbol variation related to the transition to another special figure variation pattern derivation state, and each time the symbol variation is started, generates an effect control command including the counted number of symbol variations, and stores the command in the transmission command area of the main information storage means 160. Note that the information included in the effect control command may be included in the above-described variation start command.

[0093] As described above, the main information storage means 160 is a means for temporarily storing the data read by each means and the data derived by operations by each means, etc. in the corresponding storage areas.

[0094] The main error control means 165 monitors the input information of the I / O port 104 and determines whether the gaming machine 10 is in an error state. If it is determined that the gaming machine is in an error state, an effect control command (error command) including information capable of specifying the error state is stored in the transmission command storage area of the main information storage means 160.

[0095] When an effect control command is stored in the transmission command storage area of the main information storage means 160, the main command management means 170 transmits the effect control command to the first sub-control board 200. In principle, each effect control command is transmitted in the order in which it is stored in the transmission command storage area of the main information storage means 160.

[0096] The power restoration process execution means 175 includes a return state setting means 176 and a playable state transition means 179.

[0097] The return state setting means 176 executes a return state setting process for setting the return state based on whether there is an abnormality in the RAM 103 at the time of power restoration, the state at the time of power-off immediately before the power restoration, the state of the RAM clear switch 43 at the time of power restoration, and the state of the middle frame opening sensor 76 at the time of power restoration. The return states set by this process include a game stop state and a playable state (which may or may not involve the execution of a RAM clear process). Specifically, if there is an abnormality in the RAM 103 at the time of power restoration, the game stop state is set regardless of the state of the RAM clear switch 43 and the middle frame opening sensor 76 at the time of power restoration. Also, if there is no abnormality in the RAM 103 at the time of power restoration and the RAM clear switch 43 at the time of power restoration is ON (pressed state), the RAM clear process is executed on the condition that the middle frame opening sensor 76 at the time of power restoration is ON and the playable state is set (if the middle frame opening sensor 76 at the time of power restoration is OFF, the playable state is set without executing the RAM clear process), and if there is no abnormality in the RAM 103 at the time of power restoration and the RAM clear switch 43 at the time of power restoration is OFF (not pressed state), the playable state is set without executing the RAM clear process. Here, the game stop state is a return state in which the progress of the game becomes impossible by not executing processing according to the detection result of the sensor provided at each winning port (it is not necessary to consider the detection result of the sensor itself). On the other hand, the playable state is a return state in which the progress of the game becomes possible by executing processing according to the detection result of the sensor provided at each winning port. In particular, when the RAM clear process is not executed at the time of power restoration, the game returns to the playable state at the time of the immediately preceding power cut. For example, if the immediately preceding power cut was during the execution of a big win game or a small win game, the game returns to the big win game or small win game that was being executed, and if the immediately preceding power cut was during the execution of a symbol variation, the game returns to the symbol variation that was being executed.

[0098] Also, whether there is an abnormality in the RAM 103 is determined by executing a RAM abnormality check (specifically, determining whether a backup flag is stored in the backup information area related to the target area (whether the backup flag is ON), and when the backup flag is stored (when the backup flag is ON), deriving the checksum of the complement stored in the target area and the backup information area related to the area, and when the calculation result is 0, determining that the target area is normal, and otherwise determining that the target area is abnormal) for the area related to the game in the RAM 103.

[0099] When the playable state is set, the playable state transition means 179 executes a playable state transition process for transitioning to the playable state. Specifically, in the playable state transition process, when the output of the security signal is ON, the output of the security signal is turned OFF, and the initial setting of the device is executed. Also, in the initial setting of the device, processes such as transmitting a launch permission command for permitting the launch of game balls to the payout control board 400, setting a state in which ball entry into each winning port is enabled, and setting data for starting the random number circuit 105 are executed.

[0100] Based on receiving a power-off signal from the power control board 500, the power-off processing execution means 180 executes power-off processing. Specifically, for the area related to the game in the RAM 103, a checksum of the area is derived, and the complement of the checksum is stored in the backup information area related to the game in the RAM 103, and a backup flag indicating that the power-off processing for the area has been executed is turned on (the backup flag is stored in the backup information area related to the game in the RAM 103).

[0101] As shown in FIG. 7, the first sub-control board 200 includes a sub-random number generation means 210, a normal effect control means 220, a sub-error control means 230, a lamp control means 240, a movable accessory control means 245, a sub-information storage means 260, and a sub-command management means 270. These means functionally represent what is realized by each control configuration on the first sub-control board 200 described with reference to FIG. 6. Here, the sub-information storage means 260 is a means for temporarily storing data read by the means provided in the first sub-control board 200, data derived by calculations in the means, etc. in corresponding storage areas. Also, the effect control command transmitted from the main command management means 170 is stored in the received command storage area of the sub-information storage means 260 by the sub-command management means 270. In the following description, the fact that the effect control command transmitted from the main command management means 170 is stored in the received command storage area of the sub-information storage means 260 by the sub-command management means 270 may sometimes be simply expressed as the reception of the effect control command.

[0102] The sub-random number generation means 210 can generate a random number (software random number) updated by program processing by the CPU 201, and acquires the random number at the timing when each lottery (details will be described later) by the normal effect control means 220 is executed.

[0103] Generally, the presentation control means 220 includes a presentation mode control means 221, a presentation route determination means 222, a sub-hold control means 223, a pre-reading presentation control means 224, a presentation content determination means 225, a decorative symbol control means 226, and a jackpot presentation control means 227.

[0104] When the presentation mode control means 221 receives a game state designation command, it controls the transition of the presentation mode in a manner that takes consistency with the special figure variation pattern derivation state managed on the main control board 100 side. The presentation modes in this embodiment are roughly classified into a normal mode, a challenge mode, and a RUSH mode. The normal mode corresponds to the special figure variation pattern derivation state PA, the challenge mode corresponds to the special figure variation pattern derivation state PB, and the RUSH mode corresponds to the special figure variation pattern derivation state PC.

[0105] When the presentation route determination means 222 receives a pre-determination command, it determines (sets) the presentation route corresponding to the figure variation held this time based on the result of the pre-determination included in the command (particularly, those related to the special figure variation pattern). When the special figure variation pattern corresponding to the figure variation is the above-mentioned special figure variation pattern HNP, the presentation route is not determined when the pre-determination command is transmitted, and at the start of the figure variation, the presentation route is determined based on the special figure variation pattern included in the variation start command (for example, if it is the special figure variation pattern derivation state PA, the special figure variation patterns HNP-A to HNP-D). Here, the presentation route is the presentation from the start to the end of the figure variation, which defines the process of the presentation that notifies the result of the special figure success / failure determination in the figure variation. The content of the presentation executed in the figure variation will be determined according to the presentation route corresponding to the figure variation by the presentation content determination means 225 described later.

[0106] The production route in this embodiment is roughly classified into a losing production route that notifies that the result of the special figure validity determination in this symbol variation is a loss (the result of the special figure validity determination in this symbol variation is neither a big win nor a small win), and a big win production route that notifies that the result of the special figure validity determination in this symbol variation is a big win or a small win. Further, the losing production route includes a non-developing losing production route in which a developing production is not executed, and a developing losing production route in which a developing production is executed. As will be described later, when the big win production route is determined, a developing production is executed unless otherwise specified. Here, the developing production is a production executed after the decorative symbol enters the reach state (a state in which the decorative symbol stops being displayed except for one symbol row, and the remaining symbol rows are variably displayed), and is composed of a first half and a second half, and refers to a production that notifies whether the result of the special figure validity determination in this symbol variation is a big win or a small win at the end of the second half. Therefore, in the developing production corresponding to the developing losing production route, a series of productions corresponding to the developing production are executed, and it is notified at the end of the production that the result of the special figure validity determination in this symbol variation is neither a big win nor a small win. On the other hand, in the developing production corresponding to the big win production route, a series of productions corresponding to the developing production are executed, and it is notified at the end of the production that the result of the special figure validity determination in this symbol variation is a big win or a small win. In particular, the reach state in this embodiment mainly includes a normal reach generated by a normal reach production and a sense-of-discomfort reach generated by a sense-of-discomfort reach production, and the details of these will be described later. Also, as will be described later, in this embodiment, in one production mode, for each determined special figure variation pattern, a different production route corresponds. Therefore, in the following description, the production route for the special figure variation pattern may sometimes be simply expressed by the special figure variation pattern. However, a plurality of production routes may be associated with one special figure variation pattern. In this case, one production route may be determined from the plurality of production routes corresponding to the determined special figure variation pattern. The content of the effect route corresponding to each special figure variation pattern determined in each performance mode will be described below.

[0107] In the normal mode (special figure variation pattern derivation state PA), for the special figure variation patterns HNP-A to HNP-D and the special figure variation pattern HRP, the above non-developed losing effect route corresponds. Specifically, for the special figure variation patterns HNP-A to HNP-D, the decorative pattern stops being displayed in a scattered state (a state where all the pattern rows stop displaying and the same decorative pattern is not stopped and displayed in each pattern row) without reaching the reach state, thereby corresponding to an effect route for notifying that the result of the special figure validity determination in this symbol variation is a loss. Here, the same decorative pattern refers to a decorative pattern imitating the same number, and even if the parts other than the numbers constituting the decorative pattern are different, it may be in a different form. Similarly, different decorative patterns refer to decorative patterns imitating different numbers. For the special figure variation pattern HRP, the decorative pattern reaches the reach state without going through pseudo-variation, and then, without executing the subsequent development effect, the decorative pattern stops being displayed in a scattered state, thereby corresponding to an effect route for notifying that the result of the special figure validity determination in this symbol variation is a loss. Here, pseudo-variation refers to a period delimited by, for example, the stop of the decorative pattern based on a certain rule (such as the stop of the decorative pattern where the same decorative pattern stops in the middle pattern row and the right pattern row like "5 patterns - 6 patterns - 6 patterns") during the period before the start of the development effect. Therefore, it can be said that pseudo-variation occurs only when the number of pseudo-variations becomes 2 times. That is, when the variation of the decorative pattern until it forms the reach state is 1 time, it can be said that pseudo-variation does not occur, and in that case, it can also be said that 1 time of pseudo-variation is executed. Note that the maximum number of pseudo-variations in this embodiment is 3 times, but the maximum number of pseudo-variations is not limited to this, and any number of 2 or more can be adopted.

[0108] For the special figure variation patterns HSP1-A to HSP3-B, the above-described developed losing effect route corresponds. Specifically, for the special figure variation pattern HSP1-A and the special figure variation pattern HSP1-B, the decorative pattern reaches the reach state without passing through pseudo-variation, and then a development effect that notifies that the result of the special figure validity determination in this symbol variation is a miss is executed. After the end of the development effect, there corresponds an effect route in which the decorative pattern is stopped and displayed in a scattered state. Note that the types of development effects corresponding to each special figure variation pattern are different from each other. For the special figure variation pattern HSP1-A, the development effect HEA corresponds, and for the special figure variation pattern HSP1-B, the development effect HEB corresponds. For the special figure variation pattern HSP2-A and the special figure variation pattern HSP2-B, the decorative pattern reaches the reach state through two pseudo-variations, and then a development effect that notifies that the result of the special figure validity determination in this symbol variation is a miss is executed. After the end of the development effect, there corresponds an effect route in which the decorative pattern is stopped and displayed in a scattered state. Note that, similar to the special figure variation pattern HSP1-A and the special figure variation pattern HSP1-B, the types of development effects corresponding to each special figure variation pattern are different from each other. For the special figure variation pattern HSP2-A, the development effect HEA corresponds, and for the special figure variation pattern HSP2-B, the development effect HEB corresponds. For the special figure variation pattern HSP3-A and the special figure variation pattern HSP3-B, the decorative pattern reaches the reach state through three pseudo-variations, and then a development effect that notifies that the result of the special figure validity determination in this symbol variation is a miss is executed. After the end of the development effect, there corresponds an effect route in which the decorative pattern is stopped and displayed in a scattered state. Note that, similar to the special figure variation pattern HSP1-A and the special figure variation pattern HSP1-B, the types of development effects corresponding to each special figure variation pattern are different from each other. For the special figure variation pattern HSP3-A, the development effect HEA corresponds, and for the special figure variation pattern HSP3-B, the development effect HEB corresponds.

[0109] In addition, for the special figure variation patterns ASP1-A to ASP-C, the above-mentioned big win effect route corresponds. Specifically, for special figure variation pattern ASP1-A and special figure variation pattern ASP1-B, the decorative pattern reaches the reach state without going through pseudo-variation, and then a development effect is executed to notify that the result of the special figure validity determination in this figure variation is a big win. After the end of the development effect, an effect route in which the decorative pattern is stopped and displayed in a pattern alignment state (a state in which all pattern columns are stopped and the same decorative pattern is stopped and displayed in each pattern column) corresponds. Note that the types of development effects corresponding to each special figure variation pattern are different from each other. Development effect HEA corresponds to special figure variation pattern ASP1-A, and development effect HEB corresponds to special figure variation pattern ASP1-B. For special figure variation pattern ASP2-A and special figure variation pattern ASP2-B, the decorative pattern reaches the reach state through two pseudo-variations, and then a development effect is executed to notify that the result of the special figure validity determination in this figure variation is a big win. After the end of the development effect, an effect route in which the decorative pattern is stopped and displayed in a pattern alignment state corresponds. Note that, similar to special figure variation pattern ASP1-A and special figure variation pattern ASP1-B, the types of development effects corresponding to each special figure variation pattern are different from each other. Development effect HEA corresponds to special figure variation pattern ASP2-A, and development effect HEB corresponds to special figure variation pattern ASP2-B. For special figure variation pattern ASP3-A and special figure variation pattern ASP3-B, the decorative pattern reaches the reach state through three pseudo-variations, and then a development effect is executed to notify that the result of the special figure validity determination in this figure variation is a big win. After the end of the development effect, an effect route in which the decorative pattern is stopped and displayed in a pattern alignment state corresponds. Note that, similar to special figure variation pattern ASP1-A and special figure variation pattern ASP1-B, the types of development effects corresponding to each special figure variation pattern are different from each other. Development effect HEA corresponds to special figure variation pattern ASP3-A, and development effect HEB corresponds to special figure variation pattern ASP3-B. For special figure variation pattern ASP-C, the decorative pattern reaches the reach state without going through pseudo-variation, and then development effect HEC is executed to notify that the result of the special figure validity determination in this figure variation is a big win. After the end of the development effect, an effect route in which the decorative pattern is stopped and displayed in a pattern alignment state corresponds.

[0110] Thus, in this embodiment, by corresponding the same development effects, the effect route corresponding to the special figure variation pattern ASP1-A is made to correspond to the effect route corresponding to the special figure variation pattern HSP1-A, the effect route corresponding to the special figure variation pattern ASP1-B is made to correspond to the effect route corresponding to the special figure variation pattern HSP1-B, the effect route corresponding to the special figure variation pattern ASP2-A is made to correspond to the effect route corresponding to the special figure variation pattern HSP2-A, the effect route corresponding to the special figure variation pattern ASP2-B is made to correspond to the effect route corresponding to the special figure variation pattern HSP2-B, the effect route corresponding to the special figure variation pattern ASP3-A is made to correspond to the effect route corresponding to the special figure variation pattern HSP3-A, and the effect route corresponding to the special figure variation pattern ASP3-B is made to correspond to the effect route corresponding to the special figure variation pattern HSP3-B. As a result, the contents of the effects of the associated effect routes will match from the start to near the end (the timing when the result of the special figure success / failure determination is shown by the development effect related to the effect route). Therefore, in the symbol variation in which the development effects HEA and HEB are executed, it is possible to give the player an expectation of a big win. Also, the above-described special figure variation patterns in which the effect routes in which the development effects HEA and HEB are executed are determined can also be said to be special figure variation patterns that make the player expect a big win. Furthermore, there is no corresponding development losing effect route for the special figure variation pattern ASP-C. Therefore, when the development effect HEC is executed in the symbol variation, the player can be definitely made to recognize a big win. Thus, it can be said that the effect route corresponding to the special figure variation pattern ASP-C is an effect route in which a big win is determined, and it can also be said that the special figure variation pattern is a special figure variation pattern in which a big win is determined.

[0111] Also, as shown in FIG. 9(a), when the result of the special drawing validity determination is a miss, within the range where the number of pseudo fluctuations is the same, it becomes difficult to determine in the order of the special drawing variation patterns corresponding to the production routes in which the development production HEA is executed (for example, the special drawing variation pattern HSP1-A), and the special drawing variation patterns corresponding to the production routes in which the development production HEB is executed (for example, the special drawing variation pattern HSP1-B). And when the result of the special drawing validity determination is a big win, within the range where the number of pseudo fluctuations is the same, it becomes easier to determine in the order of the special drawing variation patterns corresponding to the production routes in which the development production HEA is executed (for example, the special drawing variation pattern ASP1-A), and the special drawing variation patterns corresponding to the production routes in which the development production HEB is executed (for example, the special drawing variation pattern ASP1-B). And as described above, the development production HEC is executed only when a big win is selected. Therefore, in this embodiment, the anticipation of a big win can be enhanced in the order of the development production HEA, the development production HEB, and the development production HEC.

[0112] Furthermore, as shown in FIG. 9(a), when the result of the special drawing validity determination is a miss, within the range of the same type of development production, it becomes difficult to determine in the order of the special drawing variation patterns corresponding to the production routes in which no pseudo fluctuations occur (for example, the special drawing variation pattern HSP1-A), the special drawing variation patterns corresponding to the production routes in which the number of pseudo fluctuations is 2 (for example, the special drawing variation pattern HSP2-A), and the special drawing variation patterns corresponding to the production routes in which the number of pseudo fluctuations is 3 (for example, the special drawing variation pattern HSP3-A). And when the result of the special drawing validity determination is a big win, within the range of the same type of development production, it becomes easier to determine in the order of the special drawing variation patterns corresponding to the production routes in which no pseudo fluctuations occur (for example, the special drawing variation pattern ASP1-A), the special drawing variation patterns corresponding to the production routes in which the number of pseudo fluctuations is 2 (for example, the special drawing variation pattern ASP2-A), and the special drawing variation patterns corresponding to the production routes in which the number of pseudo fluctuations is 3 (for example, the special drawing variation pattern ASP3-A). Therefore, in this embodiment, the anticipation of a big win can be enhanced as the number of times the pseudo fluctuations are executed increases.

[0113] Also, as described above, in the special figure variation pattern HSP1-A, the special figure variation pattern HSP1-B, the special figure variation pattern ASP1-A, the special figure variation pattern ASP1-B, and the special figure variation pattern ASP-C, they reach the reach state without passing through pseudo-variations. In the special figure variation pattern HSP2-A, the special figure variation pattern HSP2-B, the special figure variation pattern ASP2-A, and the special figure variation pattern ASP2-B, they reach the reach state through two pseudo-variations. In the special figure variation pattern HSP3-A, the special figure variation pattern HSP3-B, the special figure variation pattern ASP3-A, and the special figure variation pattern ASP3-B, they reach the reach state through three pseudo-variations. Therefore, the time until reaching the reach state becomes longer in the order of the special figure variation pattern that reaches the reach state without passing through pseudo-variations, the special figure variation pattern that reaches the reach state through two pseudo-variations, and the special figure variation pattern that reaches the reach state through three pseudo-variations. However, in the symbol variation in which the special figure variation pattern ASP-C is determined, the time until reaching the reach state is longer than that of the special figure variation patterns (the special figure variation pattern HSP1-A, the special figure variation pattern HSP1-B, the special figure variation pattern ASP1-A, and the special figure variation pattern ASP1-B) that reach the reach state without passing through other pseudo-variations.

[0114] When the sub-hold control means 223 receives a hold command (hereinafter, sometimes simply expressed as the occurrence of a hold win), based on the information of the special figure 1 hold counter and the special figure 2 hold counter included in the command, it sets production data for displaying the number of hold images corresponding to the special figure 1 hold counter and the number of hold images corresponding to the special figure 2 hold counter in the hold display area (not shown) of the main display unit 81. Note that the hold image is an image that is the target of the hold prediction production that changes in various forms suggesting the degree of advantage such as the probability of a big win game occurring.

[0115] When the prediction production control means 224 receives a pre-judgment command, it determines the content of the so-called prediction production based on the result of the pre-judgment included in the command.

[0116] When the performance content determination means 225 receives a variation start command, it determines the content of the performance to be executed in the current symbol variation according to the performance route already determined by the performance route determination means 222. More specifically, for the content (performance pattern) of the performance at each performance execution timing in the symbol variation, the performance content determination means 225 determines a performance pattern lottery table to be referred to based on the performance route determined by the performance route determination means 222, and determines the content of the performance by lottery using the determined performance pattern lottery table. In particular, by doing so, it is possible to change the content of the performance according to (executed according to) the determined performance route, and it is possible to give a connection to the performance in one symbol variation.

[0117] When the decorative symbol control means 226 receives a variation start command, it determines the combination of the final (definitely stopped and displayed) decorative symbols (left symbol, middle symbol, right symbol) based on the determined stop symbol of the special symbol.

[0118] When the big win performance control means 227 receives a performance control command related to the big win game (start demo command, round start command, end demo command), it determines the content of the performance during the big win game based on the type of the performance control command and the information included in the performance control command, etc.

[0119] The normal performance control means 220 reads out the performance data of each device corresponding to each performance at the execution timing of each performance according to the content of the performance determined by the above-mentioned means provided in the first sub-control board 200. If there is performance data related to an image in the read performance data, an image control command is generated based on the performance data, and the command is stored in the transmission command storage area of the sub-information storage means 260. Further, if there is performance data related to sound in the read performance data, a voice control command related to sound is generated based on the performance data, and the command is stored in the transmission command storage area of the sub-information storage means 260.

[0120] Also, when the normal performance control means 220 returns to a playable state with the execution of the RAM clear process upon power restoration, it reads out performance data for notifying that the playable state has been reached with the execution of the RAM clear process. When the return state upon power restoration becomes a playable state without the execution of the RAM clear process, it reads out performance data for notifying that the playable state has been reached without the execution of the RAM clear process. Further, when the game stops, in addition to notifying that the game has stopped, the normal performance control means 220 reads out performance data for notifying that the execution of the RAM clear process has become necessary. Although the details of these notifications are omitted, it is preferably continuously executed for a certain period of time (for example, 30 s) after the execution starts, and the performance device for executing the notification is not limited.

[0121] When an error command is transmitted, the sub-error control means 230 determines an error notification pattern and reads out performance data for executing the error notification according to the error notification pattern. Also, the sub-error control means 230 may independently (independently of the main error control means 165) determine whether the gaming machine 10 is in an error state, and if it is determined that the gaming machine 10 is in an error state, read out performance data for executing the error notification.

[0122] The lamp control means 240 holds lamp control data for controlling the lighting of various lamps such as the frame lamp 35. For example, when there is performance data corresponding to the lamp in the performance data read out by the normal performance control means 220, the lamp control means 240 reads out the lamp control data based on the performance data and transmits the read lamp control data to the lamp to be the execution target.

[0123] When there is performance data corresponding to the movable accessory in the performance data read by the normal performance control means 220, the movable accessory control means 245 reads movable control data for controlling the movement of the movable decoration 22 or the sub-display unit 82 from the ROM 202 based on the performance data, transmits the read movable control data to the movable decoration 22 or the sub-display unit 82, and controls the movement of the movable decoration 22 or the sub-display unit 82.

[0124] As described above, the sub-information storage means 260 is means for temporarily storing data read by the means provided in the first sub-control board 200, data derived by calculations in the means, etc. in the corresponding storage areas.

[0125] The sub-command management means 270 receives the performance control command transmitted from the main control board 100 and stores the received performance command in the received command storage area of the sub-information storage means 260. Also, when an image control command is stored in the transmission command storage area of the sub-information storage means 260, the sub-command management means 270 transmits the image control command toward the second sub-control board 300. Further, when a voice control command or a volume adjustment command is stored in the storage area, the sub-command management means 270 transmits these commands toward the voice control board 310. In principle, these commands are transmitted in the order stored in the transmission command storage area of the sub-information storage means 260.

[0126] As described above, in the gaming machine 10 according to the present embodiment, a development performance is executed for a part when the decorative symbol forms a reach state, and it is notified whether or not a big win has been won by the development performance. However, such a development performance is recognized by anyone who plays the game, and once it becomes familiar, it does not lead to an improvement in the gaming interest. Therefore, there is a demand for an effect that is difficult for the player to detect and can amuse the player at the next stage after grasping the development performance. In contrast, in the gaming machine 10 according to the present embodiment, as a reach effect indicating the occurrence of a reach state, not only a normal reach effect but also an uncomfortable reach effect can be executed. The details of this function will be described below.

[0127] <Regarding the reach symbol lottery> First, with reference to FIG. 11, the details of the reach symbol lottery for determining the types of symbols (hereinafter referred to as reach symbols) constituting the reach state will be described. FIG. 11 is a diagram schematically showing a lottery table used for the reach symbol lottery. This lottery is executed upon receiving a variation start command in the special figure variation pattern derivation state PA (ordinary figure low probability) (particularly, when including a special figure variation pattern in which a reach state occurs). The range of the random number used in this lottery is 0 to 999.

[0128] As shown in FIG. 11, in the reach symbol lottery, the result of the special figure hit or miss determination in the current symbol variation and the result of the special figure stop symbol lottery in the current symbol variation are referred to, and either an even symbol reach, an odd symbol reach excluding 7 symbols, or a 7 symbol reach is determined. The current symbol variation refers to the symbol variation corresponding to the variation start command that triggers the execution of the reach symbol lottery. Specifically, when the result of the special figure hit or miss determination in the current symbol variation is a big win and symbol A is determined as the special figure stop symbol, an even symbol reach is determined with a probability of 300 / 1000 (about 1 / 3.33), an odd symbol reach excluding 7 symbols is determined with a probability of 500 / 1000 (1 / 2), and a 7 symbol reach is determined with a probability of 200 / 1000 (1 / 5). When the result of the special figure hit or miss determination in the current symbol variation is a big win and symbol B is determined as the special figure stop symbol, an even symbol reach is determined with a probability of 600 / 1000 (about 1 / 1.67), an odd symbol reach excluding 7 symbols is determined with a probability of 400 / 1000 (1 / 2.5), and a 7 symbol reach is not determined. If the result of the special symbol win / loss determination in the current symbol variation is a loss, an even symbol reach is determined with a probability of 500 / 1000 (1 / 2), an odd symbol reach excluding 7 symbols is determined with a probability of 450 / 1000 (approx. 1 / 2.22), and a 7-symbol reach is determined with a probability of 50 / 1000 (1 / 20). Although illustration is omitted, when an even symbol reach is determined, any one of the 2-symbol, 4-symbol, 6-symbol, and 8-symbol is determined by equal lottery as the symbol constituting the even symbol reach. Here, equal lottery means a lottery in which each of the lottery targets has the same probability of being determined, or a lottery in which the probabilities are substantially the same. Also, when an odd symbol reach excluding 7 symbols is determined, any one of the 1-symbol, 3-symbol, 5-symbol, and 9-symbol is determined by equal lottery as the symbol constituting the odd symbol reach.

[0129] Thus, in this embodiment, the difference between the ratio at which a 7-symbol reach is determined when the result of the special symbol win / loss determination in the current symbol variation is a big win and the ratio at which a 7-symbol reach is determined when the result of the special symbol win / loss determination is a loss is greater than the difference between the ratio at which a reach symbol other than the 7-symbol reach is determined when the result of the special symbol win / loss determination in the current symbol variation is a big win and the ratio at which a reach symbol other than the 7-symbol reach is determined when the result of the special symbol win / loss determination is a loss. Therefore, it can be said that the 7 symbols are the reach symbols with the highest winning expectation for a big win. Also, when the result of the special symbol win / loss determination in the current symbol variation is a big win and symbol A is determined as the special symbol stop symbol, a 7-symbol reach may be determined. On the other hand, when the result of the special symbol win / loss determination in the current symbol variation is a big win and symbol B is determined as the special symbol stop symbol, a 7-symbol reach is not determined. Therefore, it can be said that the 7-symbol reach is a reach symbol that determines that the special symbol stop symbol related to the big win is symbol A (a more advantageous special symbol stop symbol than symbol B) when winning a big win. That is, in this embodiment, it can be said that the 7-symbol reach is more advantageous than other reach symbols from the viewpoints of the winning expectation of a big win and the advantage degree of the big win itself.

[0130] <Regarding the types of reaches> Next, using FIG. 12, the types of reaches (reach states) that can occur in the reach effect in this embodiment will be described. FIG. 12(a) is a diagram showing a specific example of a normal reach, and FIG. 12(b) is a diagram showing a specific example of an uncomfortable reach.

[0131] As shown in FIGS. 12(a) and 12(b), the decorative pattern in this embodiment is composed of a numerical image sg indicating a number and a character image kg indicating a character corresponding to the number. And in the reach composed of such a decorative pattern, there are a normal reach and an uncomfortable reach in which the numerical image sg is closer to the center than the normal reach when viewed in the width direction (the left-right direction, which is substantially orthogonal to the variation display direction of each pattern column).

[0132] Specifically, as shown in FIG. 12(a), in the normal reach, in the decorative pattern zg1 displayed (temporarily stopped display) in the left pattern column, the character image kg and the numerical image sg are arranged so that the distance between the center line of the maximum width of the decorative pattern and the center line of the maximum width of the numerical image sg constituting the decorative pattern becomes the distance D1. Also, in the normal reach, in the decorative pattern zg2 displayed in the right pattern column, the character image kg and the numerical image sg are arranged so that the distance between the center line of the maximum width of the decorative pattern and the center line of the maximum width of the numerical image sg constituting the decorative pattern becomes the distance D2. In particular, in this embodiment, the distance D1 and the distance D2 are configured to be different.

[0133] As shown in FIG. 12(b), in the uncomfortable reach, in the decorative pattern zg1 displayed in the left pattern column, the character image kg and the numerical image sg are arranged so that the distance between the center line of the maximum width of the decorative pattern and the center line of the maximum width of the numerical image sg constituting the decorative pattern becomes the distance D3. Also, in the sense-of-discomfort reach, in the decorative symbol zg2 displayed in the right symbol column, the character image kg and the numerical image sg are arranged such that the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image sg that constitutes the decorative symbol is the distance D4. And both of these distances (distance D3 and distance D4) are shorter than distance D1 and shorter than distance D2. In particular, distance D3 and distance D4 are the same.

[0134] Note that in Fig. 12(a), an example where the normal reach is composed of 7 symbols is shown, but the reach state may be composed of symbols other than 7 symbols. In any case, the relationship between the above-described numerical image sg and the character image kg (particularly, distance D1 and distance D2) is the same. On the other hand, the sense-of-discomfort reach in the present embodiment is always composed of 7 symbols. Also, in the present embodiment, there is no difference in the position of the numerical image sg in the height direction (vertical direction) of the decorative symbol in either the decorative symbol that constitutes the normal reach or the decorative symbol that constitutes the sense-of-discomfort reach.

[0135] <Regarding the reach effect> Next, the details of the reach effect in the present embodiment will be described with reference to Figs. 13 to 16. Fig. 13 is a flow of the reach effect control process, and this process is executed triggered by the reception of a variation start command in the special drawing variation pattern derivation state PA (ordinary drawing low probability) (particularly, when including the special drawing variation pattern in which the reach state occurs). Fig. 14(a) schematically shows a lottery table used for the execution lottery of the sense-of-discomfort reach effect, and Fig. 14(b) schematically shows a lottery table used for the selection lottery of the effect pattern related to the sense-of-discomfort reach effect. The range of the random numbers used in these lotteries is 0 to 999.

[0136] As shown in FIG. 13, in step S202 which is the first step of the reach effect control process for controlling the reach effect, it is determined whether a development effect is to be executed in the current symbol variation. If this condition is satisfied, the process proceeds to step S204. If this condition is not satisfied, the process proceeds to step S214. Here, the current symbol variation refers to the symbol variation corresponding to the variation start command that triggered the execution of the reach effect control process. In step S204, it is determined whether a 7-symbol reach has been determined in the current symbol variation. If this condition is satisfied, the process proceeds to step S206. If this condition is not satisfied, the process proceeds to step S214.

[0137] In step S206, a lottery for executing the sense-of-discrepancy reach effect is conducted. Specifically, as shown in FIG. 14(a), in the lottery for executing the sense-of-discrepancy reach effect, if the result of the special symbol win / loss determination in the current symbol variation is a big win, the probability of winning this lottery is 300 / 1000 (about 1 / 3.33), and the probability of not winning this lottery is 700 / 1000 (about 1 / 1.43). Also, if the result of the special symbol win / loss determination in the current symbol variation is a loss, the probability of winning the lottery for executing the sense-of-discrepancy reach effect is 100 / 1000 (1 / 10), and the probability of not winning this lottery is 900 / 1000 (about 1 / 1.11).

[0138] In step S208, it is determined whether the lottery for executing the sense-of-discrepancy reach effect has been won. If this condition is satisfied, the process proceeds to step S210. If this condition is not satisfied, the process proceeds to step S214.

[0139] In step S210, a lottery for selecting the effect pattern related to the sense-of-discrepancy reach effect is executed. Specifically, as shown in FIG. 14(b), in the selection lottery of the production pattern related to the sense-of-discrepancy reach production, when the result of the special figure validity determination in the current symbol variation is a big win, the production pattern P1 is determined with a probability of 300 / 1000 (about 1 / 3.33), the production pattern P2 is determined with a probability of 400 / 1000 (1 / 2.5), the production pattern P3 is determined with a probability of 200 / 1000 (1 / 5), and the production pattern P4 is determined with a probability of 100 / 1000 (1 / 10). On the other hand, in the selection lottery of the production pattern related to the sense-of-discrepancy reach production, when the result of the special figure validity determination in the current symbol variation is a loss, the production pattern P1 is determined with a probability of 600 / 1000 (about 1 / 1.67), the production pattern P2 is determined with a probability of 300 / 1000 (about 1 / 3.33), the production pattern P3 is determined with a probability of 100 / 1000 (1 / 10), and the production pattern P4 is not determined in the selection lottery. Considering these probabilities, in this embodiment, the ratio of the results of the special figure validity determination related to the symbol variation when production patterns other than the production pattern P1 are determined being a big win is higher than the ratio of the results of the special figure validity determination related to the symbol variation when the production pattern of the production pattern P1 is determined being a big win. That is, it can be said that production patterns other than the production pattern P1 (production patterns P2 to P4) have a higher big win winning expectation than the production pattern P1. Furthermore, when comparing production patterns P2 to P4, the big win winning expectations are high in the order of production pattern P2, production pattern P3, and production pattern P4. In particular, it can be said that the production pattern P4 is the production pattern in which the big win is confirmed. Note that the details of the sense-of-discrepancy reach production related to these production patterns will be described later, but all of these production patterns are the reach productions in which the above-described sense of discrepancy occurs.

[0140] In step S212, the production data related to the sense-of-discrepancy reach production of the production pattern determined by the selection lottery is set, and then the reach production control process is terminated. Thereby, the sense-of-discrepancy reach production is executed. In step S214, production data related to the normal reach effect is set, and then the reach effect control process is terminated. As a result, the normal reach effect is executed.

[0141] As described above, in this embodiment, for the reach effect that displays a reach state (7-symbol reach) composed of 7 symbols, there are a normal reach effect that displays a normal reach and a sense-of-discrepancy reach effect that displays a sense-of-discrepancy reach, and the winning expectation of the jackpot is different between the sense-of-discrepancy reach effect and the normal reach effect. And regarding the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image that constitutes the decorative symbol, the distances (distance D1, distance D2) related to the normal reach and the distances (distance D3, distance D4) related to the sense-of-discrepancy reach are different. According to this, by incorporating a sense-of-discrepancy effect that is difficult for the player to perceive into the decorative symbol that the player pays attention to, it is possible to improve the interest of the player who is bored with the conventional variable effects such as the development effect.

[0142] In achieving the above effect, the following modification examples are allowed, and these modification examples can also be adopted for each invention described below as long as there is no contradiction. First, regarding the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image that constitutes the decorative symbol, it is not limited to the case where the distance related to the sense-of-discrepancy reach is shorter than the distance related to the normal reach as in this embodiment, and it is allowed that the length relationship between these distances is reversed. Furthermore, in this embodiment, the winning expectation of the jackpot in the sense-of-discrepancy reach effect is higher than the winning expectation of the jackpot in the normal reach effect, but it is allowed that the high and low of these winning expectations of the jackpot are reversed. Also, in this embodiment, the target for generating a sense of discrepancy is the symbol combination related to the reach state. However, as long as it is a symbol combination composed of two or more symbol columns, the symbol combination that generates a sense of discrepancy is not limited to the symbol combination that constitutes the reach state, and it may be a symbol combination composed of all the symbol columns. Furthermore, in the present embodiment, the difference in the distance described above occurs for each of the symbol combinations of the target that causes a sense of discomfort (each of the two decorative symbols constituting the reach state), but it is not limited to this. That is, it is sufficient that the difference in the distance described above occurs in a part of the symbol combination of the target. Also, it is allowed that the above distance D1 and the above distance D2 are the same. In addition, the difference in the degree of advantage between the above-described discomfort reach effect and the normal reach effect is not limited to being caused by the difference in the winning expectation of the jackpot as in the present embodiment, but may also be caused by the difference in the degree of advantage of the jackpot game itself that occurs when winning the jackpot. That is, the difference in the degree of advantage between the discomfort reach effect and the normal reach effect may be any difference in the degree of advantage related to the jackpot game.

[0143] Therefore, in the gaming machine 10, the symbol control means (the decorative symbol control means 226) can display a specific symbol combination (7-symbol reach) that is composed of two or more symbol columns among a plurality of symbol columns and includes a specific decorative symbol (7 symbols) related to a specific number. The specific decorative symbol includes a first specific decorative symbol and a second specific decorative symbol. Regarding a predetermined distance that is the distance between the center line with respect to the maximum width of the numerical part (numerical image sg) of the decorative symbol and the center line with respect to the maximum width of the decorative symbol, the predetermined distance (distance D1, distance D2) related to the first specific decorative symbol and the predetermined distance (distance D3, distance D4) related to the second specific decorative symbol are different. The specific symbol combination includes a first specific symbol combination (7-symbol reach of normal reach) that includes the first specific decorative symbol and does not include the second specific decorative symbol, and a second specific symbol combination (discomfort reach) that includes the second specific decorative symbol. In other words, the degree of advantage related to the privilege is different when the second specific symbol combination is displayed and when the first specific symbol combination is displayed.

[0144] In particular, in the present embodiment, the reach state is adopted for the above-described specific symbol combination, and a plurality of the above-described specific decorative symbols are included in the above-described specific symbol combination. According to this, it is possible to make it easier to recognize the difference between the above first specific symbol combination and the above second specific symbol combination (the sense of incongruity in the sense-of-incongruity reach effect). This contributes to reducing the difficulty level (the difficulty of detection) of the sense-of-incongruity reach effect. In addition, when achieving the above effect, if the above specific decorative symbol is included in a plurality in the above specific symbol combination, the above specific symbol combination is not limited to the reach state.

[0145] Also, in the present embodiment, regarding the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image constituting the decorative symbol, the distances (distance D3, distance D4) related to the sense-of-incongruity reach are shorter than the distances (distance D1, distance D2) related to the normal reach. According to this, in the sense-of-incongruity reach, it is possible to make it easier to recognize the numerical image.

[0146] Also, as described above, unlike the present embodiment, regarding the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image constituting the decorative symbol, the distances (distance D3, distance D4) related to the sense-of-incongruity reach may be made longer than the distances (distance D1, distance D2) related to the normal reach. According to this, it is possible to make it easier to recognize the numerical image in the normal reach and then show the sense-of-incongruity reach.

[0147] Therefore, in the gaming machine 10, it can be said in other words that the predetermined distances (distance D3, D4) related to the second specific decorative symbol are shorter than the predetermined distances (distance) related to the first specific decorative symbol.

[0148] Also, as described above, in the present embodiment, the distance D1 and the distance D2 are configured to be different (refer to FIG. 12(a) and its description). According to this, it is possible to increase the difficulty level of detecting the sense-of-incongruity reach.

[0149] Therefore, in the gaming machine 10, it can be said that the first specific symbol combination (the 7-symbol reach in the normal reach) includes a plurality of first specific decorative symbols, and the predetermined distance (distance D1) related to one first specific decorative symbol included in the first specific symbol combination is different from the predetermined distance (distance D2) related to another specific decorative symbol included in the first specific symbol combination.

[0150] <Regarding the production pattern of the sense-of-dissonance reach effect> Next, with reference to FIGS. 15 and 16, the details of the production pattern related to the sense-of-dissonance reach effect will be described. FIG. 15(a) is a timing chart showing the flow of the sense-of-dissonance reach effect related to the production pattern P1, and FIG. 15(b) is a timing chart showing the flow of the sense-of-dissonance reach effect related to the production pattern P2. FIG. 16(a) is a timing chart showing the flow of the sense-of-dissonance reach effect related to the production pattern P3, and FIG. 16(b) is a timing chart showing the flow of the sense-of-dissonance reach effect related to the production pattern P4.

[0151] As shown in FIG. 15(a), in the sense-of-dissonance reach effect related to the production pattern P1, the sense-of-dissonance reach occurs from the timing (timing t1) when the reach effect is generated, that is, the timing when the reach state first occurs, and continues until the end (timing t2) of the reach effect. In particular, the length of the execution period (timing t1 to timing t2) of the reach effect in the present embodiment is 2500 ms. Although not shown, the flow of the normal reach effect is the same as that of the sense-of-dissonance reach in the sense-of-dissonance reach effect related to the production pattern P1 with the sense-of-dissonance reach replaced by the normal reach. As shown in FIG. 15(b), in the sense-of-dissonance reach effect related to the production pattern P2, the normal reach occurs at the timing (timing t1) when the reach effect is generated. Then, at the timing (timing t3) after the period T1 has elapsed from that timing, the normal reach switches to the sense-of-dissonance reach, and the sense-of-dissonance reach continues until the end of the reach effect.

[0152] As shown in Fig. 16(a), in the sense-of-discomfort reach effect related to the effect pattern P3, a normal reach occurs at the timing (timing t1) when the reach effect is generated. Then, at the timing (timing t4) after the period T2 has elapsed from the said timing, the said normal reach switches to a sense-of-discomfort reach, and the sense-of-discomfort reach continues until the end of the reach effect. In particular, the period T2 (700 ms in this embodiment) is longer than the period T1 (300 ms in this embodiment). As shown in Fig. 16(b), in the sense-of-discomfort reach effect related to the effect pattern P4, a normal reach occurs at the timing (timing t1) when the reach effect is generated. Then, at the timing (timing t5) after the period T3 has elapsed from the said timing, the said normal reach switches to a sense-of-discomfort reach, and the sense-of-discomfort reach continues until the end of the reach effect. In particular, the period T3 (1200 ms in this embodiment) is longer than the period T2.

[0153] Thus, in this embodiment, except for the effect pattern P1, in the sense-of-discomfort reach effect (effect patterns P2 to P4), after a normal reach has occurred once, the normal reach switches to a sense-of-discomfort reach. And as described above, when the effect patterns P2 to P4 are determined as the effect patterns of the sense-of-discomfort reach effect, the degree of advantage related to a big win is higher than when the effect pattern P1 is determined as the effect pattern of the sense-of-discomfort reach effect. According to this, when an effect pattern with a high big win expectation degree (effect patterns P2 to P4) is determined, by making the player recognize a sense-of-discomfort reach after recognizing a normal reach, it is possible to make it easier to recognize the sense of discomfort related to the sense-of-discomfort reach.

[0154] Therefore, in the gaming machine 10, when the first specific symbol combination (7-symbol reach of the normal reach) is displayed, there are a first time when the first specific symbol combination switches to the second specific symbol combination (sense-of-discomfort reach) and a second time when the first specific symbol combination does not switch to the second specific symbol combination. In other words, it can be said that the degree of advantage related to a privilege (big win game) is higher at the first time than at the second time.

[0155] In particular, in the present embodiment, in the order of the production pattern P2, the production pattern P3, and the production pattern P4, the period during which the normal reach until switching to the sense of incongruity reach is displayed is long, and the degree of advantage related to the jackpot is high in this order. According to this, when a production pattern (production pattern P2 to production pattern P4) with a higher jackpot winning expectation is determined, by making it easier to recognize the sense of incongruity reach after recognizing the normal reach, the production effect related to the sense of incongruity reach production can be enhanced. In achieving the above effect, the length of the period during which the normal reach until switching to the sense of incongruity reach is displayed may be the same between the production pattern P2 and the production pattern P3, or the length of the period may be the same between the production pattern P3 and the production pattern P4. That is, it is sufficient that the degree of advantage related to the jackpot tends to increase as the length of the period increases. Also, in the present embodiment, although no animation is used when switching from the normal reach to the sense of incongruity reach, an animation may be used to gradually switch from the normal reach to the sense of incongruity reach. Further, when switching from the normal reach to the sense of incongruity reach, it may be switched from the normal reach to the sense of incongruity reach with a state where the reach state is once hidden in between.

[0156] Therefore, in the gaming machine 10, in the above first case, it can be paraphrased that the longer the period during which the first specific symbol combination (7-symbol reach of the normal reach) is displayed, the higher the degree of advantage related to the privilege (jackpot game) in the above first case tends to be.

[0157] Also, in the present embodiment, in the sense of incongruity reach production of the production pattern P1, that is, when the sense of incongruity reach is displayed from the beginning, the decorative symbols constituting the sense of incongruity reach are variably displayed in the symbol columns (the left symbol column, the right symbol) during the variation until the sense of incongruity reach is displayed. On the other hand, in the sense-of-discomfort reach effect of performance patterns P2 to P3, that is, when the normal reach effect is displayed without the sense-of-discomfort reach effect being displayed from the beginning, the decorative symbols that constitute the normal reach effect in the symbol sequence (the left symbol sequence, the right symbol) vary and are displayed during the variation until the normal reach effect is displayed. According to this, the difference in the difficulty of recognizing the sense of discomfort related to the sense-of-discomfort reach effect can be increased between the sense-of-discomfort reach effect of performance pattern P1 and the sense-of-discomfort reach effects of performance patterns P2 to P3.

[0158] <Regarding a modification example of the sense-of-discomfort reach effect> Next, a modification example of the sense-of-discomfort reach effect will be described with reference to FIG. 17. FIGS. 17(a) and 17(b) are diagrams showing a modification example of the sense-of-discomfort reach effect.

[0159] As shown in FIG. 17(a), the sense-of-discomfort reach effect in the present embodiment may be such that the decorative symbols in the left symbol sequence that constitute the reach state are replaced with the same decorative symbols as those in the left symbol sequence that constitutes the normal reach effect (the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image that constitutes the decorative symbol is distance D1). Also, as shown in FIG. 17(b), the sense-of-discomfort reach effect in the present embodiment may be such that the decorative symbols in the right symbol sequence that constitute the reach state are replaced with the same decorative symbols as those in the right symbol sequence that constitutes the normal reach effect (the distance between the center line of the maximum width of the decorative symbol and the center line of the maximum width of the numerical image that constitutes the decorative symbol is distance D2). According to these, it is possible to make it easier to determine whether the reach state is a sense-of-discomfort reach effect by a plurality of decorative symbols that constitute the reach state.

[0160] Therefore, in the gaming machine 10, it can be said that the second specific symbol combination (sense-of-discomfort reach effect) includes the first specific decorative symbol in addition to the second specific decorative symbol.

[0161] <Regarding other modification examples> Modification examples not described in the above description will be listed below.

[0162] First, the digital images and character images that constitute the discomfort reach-related decorative pattern (especially those different from the decorative pattern that constitutes the normal reach) in the present embodiment adopt the same ones as the normal reach, but the size of some or all of these images may be made larger or smaller than that of the normal reach. In particular, when the size is changed in this way, the above-described distance D3 and distance D4 may be the same length as distance D1 and distance D2. However, even in that case, since the ratio of the distance occupied by each center line (the center line of the maximum width of the decorative pattern, the center line of the maximum width of the digital image that constitutes the decorative pattern) to the maximum width of the decorative pattern is different, it functions in the same way as the discomfort reach according to the present embodiment. Furthermore, in the present embodiment, there is no difference in the position of the digital image in the height direction (vertical direction) of the decorative pattern in either the decorative pattern that constitutes the normal reach or the decorative pattern that constitutes the discomfort reach, but there may be such a difference.

[0163] Also, the above-described normal reach effect and discomfort reach effect were executed during the execution of the pattern variation in the special drawing variation pattern derivation state PA, but it is not limited to this, and these reach effects may be executed in the special drawing variation pattern derivation state PB or the special drawing variation pattern derivation state PC (both are general drawing high probability).

[0164] Also, the normal reach effect and discomfort reach effect in the present embodiment were effects using only the main display unit 81, but in addition to the device, a device different from the main display unit 81 such as the speaker 33 may be adopted.

[0165] Also, the gaming machine 10 according to the present embodiment adopts a so-called one-kind two-kind hybrid machine that can derive both a big win and a small win that can cause a big win game in the special drawing win / loss determination, but it is not limited to this, and a machine that can derive only a so-called two-kind win may be adopted.

[0166] In addition, regarding the probabilities, ratios, frequencies, and numbers of times in this embodiment, as long as the respective relationships are ensured, the smaller value may be 0 or the larger value may be the maximum value. In particular, regarding the high or low of each ratio described above, as long as the appearance aspect is ensured, the control for realizing the high or low of each ratio is not limited. In addition, each lottery value in the lottery table illustrated in this embodiment is an example, and as long as the magnitude relationship between the lottery tables is maintained, each lottery value may adopt any value within the range.

[0167] In the above description, the return state at power restoration is determined by referring to the state of the RAM clear switch 43 at power restoration. However, it may be configured to refer to whether the ON state time of the RAM clear switch 43 from power restoration exceeds a specified time (for example, 3 s). By doing so, the occurrence of incorrect RAM clear processing can be further suppressed.

[0168] In the above description, when determining the return state at power restoration, the state of the middle frame opening sensor 76 (the open / closed state of the middle frame 17) is referred to. However, the return state may be set without referring to the state. In this case, uniformly, the return state at power restoration may be set according to the case where the middle frame opening sensor 76 is ON (the middle frame 17 is in the open state).

[0169] The present invention described above is not limited to the above description, and includes various modifications, improvements, etc. as long as the object of the present invention is achieved.
