  The slide door 302 is formed in a flat plate shape having a left-right length corresponding to the left-right length of the special prize inflow port 301 and extending in the left-right direction. Below the slide door 302, a substantially flat door support member 316 extending in the front-rear and left-right directions is provided. The slide door 302 is placed and supported on the upper surface of the door support member 316, and is provided so as to be slidable in the front-rear direction (direction perpendicular to the board surface of the game board 10) along the upper surface of the door support member 316. The large winning inflow port 301 is configured to open and close by sliding movement. A convex portion 302a that protrudes downward is formed at a substantially central portion of the lower surface of the slide door 302, and this convex portion 302a is inserted into a groove portion 316a that is formed to extend back and forth on the upper surface of the door support member 316. It has become. When the sliding door 302 is slid in the front-rear direction, the convex portion 302a slides in the groove portion 316a, and the left and right side surfaces of the sliding door 302 slide on the inner surfaces of the left and right side walls of the door support member 316. Thus, the slide movement is guided.

The front and rear lengths of the slide door 302 are formed so that the front end of the slide door 302 is slanted so that the left end side is smaller than the right end side (see FIG. 6). Therefore, when the slide door 302 is slid to the maximum position to close the grand prize inflow port 301, the right front end of the slide door 302 is close to the inner surface of the inflow port forming member 312, while the slide door 302 A predetermined gap is formed between the left front end and the inner surface of the inflow port forming member 312. However, this gap is a gap smaller than the diameter of the game ball, and the game ball does not flow into the flow path forming member 310 from this gap. The front end portion of the sliding door 302 is formed in a tapered shape with the lower surface side formed obliquely and tapered.

  At the rear end of the slide door 302, a cutout portion 302b that is cut out in a rectangular shape up to a substantially central portion is formed on the left and right, and the weight of the slide door 302 is reduced by the left and right cutout portions 302b. Yes. A substantially rectangular engagement hole 305 penetrating vertically is formed in a substantially central portion of the slide door 302, and a distal end portion of an arm member 325 of a door opening / closing mechanism 320 described later is inserted into the engagement hole 305. It has become so.

  The door opening / closing mechanism 320 includes a special winning solenoid 321 and an arm member 325 that is rotated by the special winning solenoid 321. The large winning solenoid 321 is a pull (suction) solenoid that always sucks the plunger 321a while energized, and the plunger 321a extends in the left-right direction (direction parallel to the board surface of the game board 10). It is disposed below the door support member 316. The big winning solenoid 321 is configured such that when the current is interrupted, the plunger 321a is pushed out by the force of a spring (not shown). An engagement member 322 having an L-shaped claw portion 322a that protrudes rightward and extends forward is attached to the distal end portion of the plunger 321a.

  The arm member 325 includes a base portion 326 that is fitted to a cylindrical engagement protrusion 316 b that protrudes upward from the upper surface of the door support member 316 and is provided rotatably, and an arm portion 327 that extends from the base portion 326. It is configured. The arm member 325 is provided between the door support member 316 and the slide door 302 so as to be rotatable in the front-rear direction around the engagement protrusion 316 b of the door support member 316. The base portion 326 is formed with a base end side convex portion 326 a extending downward, and the base end side convex portion 326 a is engaged with the claw portion 322 a of the engaging member 322. Therefore, when the engaging member 322 is moved left and right by the operation of the plunger 321a of the big prize solenoid 321, the base end side convex portion 326a of the arm member 325 is moved right and left by the claw portion 322a of the engaging member 322 (nail). The arm portion 327 of the arm member 325 is rotated back and forth.

  A tip side convex portion 327 a extending upward is formed at the tip portion of the arm portion 327 of the arm member 325, and the tip side convex portion 327 a is inserted into the engagement hole 305 of the slide door 302. Yes. Therefore, as shown in FIG. 6, when the arm member 325 is rotated forward by the big prize solenoid 321 as described above, the front side of the front end side convex portion 327 a of the arm member 325 is the engagement hole 305 of the slide door 302. The slide door 302 is pushed forward by coming into contact with the front surface, and the slide door 302 can be slid and moved to the closed position where the prize winning inlet 301 is closed. On the other hand, when the arm member 325 is rotated rearward by the big winning solenoid 321, the rear surface side of the tip side convex portion 327 a of the arm member 325 abuts on the rear surface of the engagement hole 305 of the slide door 302 to move the slide door 302 rearward. The sliding door 302 can be slid and moved to the open position where the winning prize inlet 301 is opened.

An arm-side lock surface 327b is formed on the front surface side of the tip side convex portion 327a of the arm member 325, and a door-side lock surface 305b is formed on the front surface of the engagement hole 305 of the slide door 302. As shown in FIG. 7, 327 b and 305 b are formed on inclined surfaces that are inclined in the front-rear direction (angled in the front-rear direction) with respect to the tangent to the rotation circle A of the arm member 325. Therefore, when a force F is applied to the sliding door 302 in the closed position so as to slide in the opening direction (rearward), the arm side lock surface 327b and the door side lock surface 305b come into contact with each other, and these lock surfaces 327b and 305b are brought into contact. Thus, the force F is changed to a force F ′ that moves the slide door 302 to the left. Since the sliding door 302 is restricted from moving leftward by the left side wall of the door support member 316, the arm member 325 serves as a support rod to restrict sliding movement of the sliding door 302 in the opening direction. The Thus, the arm side lock surface 327b of the arm member 325 and the door side lock surface 305b of the slide door 302 constitute a lock mechanism when the slide door 302 is located at the closed position.

  Further, a stepped portion 327c is formed on the front side of the tip side convex portion 327a of the arm member 325 on the left side of the arm side lock surface 327b. When the arm member 325 is rotated forward by the big prize solenoid 321 and the slide door 302 is slid in the closing direction, the stepped portion 327c makes it easy to push and slide the front surface of the engagement hole 305 of the slide door 302. Yes.

  According to the prize winning device 300 configured as described above, when the slide door 302 is positioned at the closing position for closing the prize winning inlet 301, the slide door 302 is slid in the opening direction (backward). When the force F is applied, the arm-side lock surface 327b and the door-side lock surface 305b come into contact with each other, and the force F is changed to a force F ′ that moves the slide door 302 to the left by these lock surfaces 327b and 305b. The arm member 325 is configured to have a lock mechanism that serves as a support rod to receive the force F and restrict the sliding movement of the sliding door 302 in the opening direction. Therefore, the lock is released due to errors in parts and assembly, or wear of parts, as in the conventional lock mechanism (a configuration in which the tip (convex part) of the claw part and the protrusion part (convex part) of the open / close door abut). Can be prevented. Further, since the lock mechanism is provided at a position away from the plunger 321a of the big winning solenoid 321, the lock is difficult to be released even if the plunger 321a moves slightly.

  Further, according to the big prize device 300, by changing the arrangement and length of the arm member 325, the stroke of the plunger 321a of the big prize solenoid 321 can be set short and close to the solenoid body. As a result, since the portion where the torque of the big prize solenoid 321 is large can be used, the opening / closing operation of the sliding door 302 can be performed stably. Further, since the portion where the torque of the special winning solenoid 321 is large can be used, the spring load for pushing the plunger 321a when the current is interrupted can be increased, thereby causing the plunger 321a to move slightly. This can be suppressed. Further, since the spring load can be increased, when the slide door 302 is closed, the game ball is sandwiched between the front end portion of the slide door 302 and the rear surface of the inlet forming member 312 (large winning inlet 301) ( It is also possible to prevent so-called spheres).

  Further, according to the big prize device 300, the big prize solenoid 321 is arranged in a state in which the plunger 321a extends in the direction parallel to the board surface of the game board 10 (left and right direction), so that it is applied to the board surface by an external force. The plunger 321a can be prevented from moving slightly even if it receives vibration in a direction perpendicular to the plunger 321a. The arm member 325 is formed of a resin material. However, in order to improve the strength of the arm member 325, the shape of the arm member 325 may be changed, or the arm member 325 may be formed of a metal material.

  The special symbol is variably displayed on the symbol display device 25 shown in FIG. The special symbol is a symbol corresponding to the result of the lottery performed in the game control device 200 when the game ball enters the start winning device 14, and the variation display is stopped in a predetermined hit state. When displayed, a jackpot as a special game is generated. The symbol display device 25 is a display device composed of, for example, a 7-segment LED. Configured to display.

Are electrically connected to each game effect device.

  As shown in FIG. 3, the effect display device 100 includes a first liquid crystal unit 110 and a second liquid crystal unit 120 disposed in front of the first liquid crystal unit 110 and between the game board 10. It is configured. The first liquid crystal unit 110 includes a rectangular first liquid crystal panel 111 having a size covering substantially the entire window portion 10a of the game board 10 and is output from the sub control board 41 via the image relay board 80. A signal is received, and the received control signal is transmitted to the first liquid crystal panel 111, so that the first liquid crystal panel 111 variably displays effect images and decorative symbols according to game development.

  The second liquid crystal unit 120 includes a slide movement mechanism (sliding movement mechanism) that slides the left and right second liquid crystal panels 121L and 121R and the pair of left and right second liquid crystal panels 121L and 121R in the left-right direction. (Not shown). The second liquid crystal unit 120 receives the control signal output from the sub-control board 41, and transmits the received control signal to the left and right second liquid crystal panels 121L and 121R and the slide moving mechanism, and the left and right second liquid crystals. The panels 121L and 121R are slid left and right, and effect images corresponding to the left and right second liquid crystal panels 121L and 121R are displayed.

  Next, a gaming method and a control flow performed in the gaming board 10 configured as described above will be described. The game ball launched into the game area PA of the game board 10 by the launching mechanism flows down in a direction corresponding to the way of hitting while hitting a plurality of game nails and windmills. Then, when a game ball flows into each winning opening of the general winning device 13, the starting winning device 14, and the big winning device 300, a predetermined number of winning balls corresponding to the type of the winning device is the upper ball tray 6 or the lower ball plate 7 To be paid out. The game balls that have flowed into any of the prize winning ports of the general winning device 13 or the like are discharged to the rear side of the game board 10 as safe balls and processed. On the other hand, the game balls that have not flowed into any winning opening are discharged from the out port 18 to the rear side of the game board 10 as an out ball and processed.

When the game ball flows into the start winning port of the start winning device 14, a lottery determination is performed in a game control device 200 described later, a special symbol is variably displayed on the symbol display device 25, and a decorative symbol is variably displayed on the effect display device 100.

In the variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol and the decorative symbol is stopped when the variation display time elapses.

  For example, the decorative symbols can be displayed as a final stop mode by changing the symbols in all three rows as the reel machine is rotating at the start of the change, and stopping the rows one by one when the change end timing is approached. The symbol combination is displayed. If the special symbol and the decorative symbol at the time of the stop are in a stop mode indicating a big hit, the game shifts to a special game that is more advantageous to the player than the normal game, and the special winning device 300 (large winning mouth) Opening and closing operations are started. The decorative pattern stop mode indicating a big hit is, for example, a combination mode in which three types of symbols match.

  The variation effect pattern includes a normal loss effect pattern, a reach failure effect pattern, and a reach jackpot effect pattern. The normal off effect pattern is an effect pattern for displaying a normal off symbol combination. The reach out effect pattern is an effect pattern for displaying an out symbol combination through a reach state, which is a big win if one more symbols are arranged. The reach jackpot effect pattern is an effect pattern when displaying a jackpot symbol combination through the reach state. In particular, the patterns when reaching the reach state include patterns with various long and short fluctuation times. Reach patterns with relatively short fluctuation times are called “normal reach”, and reach patterns with long fluctuation times are called “super reach”. ".

  If the winning / losing lottery corresponds to a big hit, a special game is executed. The special game is started by displaying an effect screen called a start demo. After the start demonstration screen is displayed, the grand prize inflow port 301 of the grand prize winning device 300 is opened, and after the opening continues for about 30 seconds, for example, after nine or more game balls flow in, it is temporarily closed. From such opening to closing of the big prize inflow port 301 is basically called a unit game, a plurality of short-time opening may be repeated during one unit game. After opening / closing (unit game) of the big prize inflow port 301 is repeated a predetermined plurality of times, for example, 16 times, the special game is ended by displaying an effect screen called an end demonstration time.

  When a special game occurs and a predetermined condition such as a lottery is satisfied, in the normal game after the special game is finished, a special design and a decorative design that are one of the specific games are played Be started. The short-time game (hereinafter referred to as “time-short”) is a game in which the change display time of the special symbol and the decorative symbol is shorter than the normal state. The variation time of special symbols and decorative symbols is restored to the original variation time after a predetermined number of variations, for example, 100 variations are displayed. However, if a big hit occurs before the number of variations is reached, the time reduction ends. To do. Because the time required to change special symbols and decorative symbols is shortened due to the shorter time, the time until a big hit can be reduced compared to the normal state where the symbols change with the normal fluctuation time. The acquisition easiness of can be relatively increased.

Next, the game control configuration of the pachinko gaming machine PM will be described with reference to FIG. The pachinko gaming machine PM is configured to include the game control device 200 including the main control board 40 and the sub control board 41 described above. The game control device 200 includes a main control board 40 that controls the overall operation of the pachinko gaming machine PM including the basic operation of the game and the progress of the game, and the sub-control device that controls the overall effects such as the decorative display variation display and electrical decoration. It is comprised in the form which shared the function with 41. The game control device 200 is configured with hardware and other electronic components such as a ROM and a RAM for storing data and programs, and a CPU used for arithmetic processing. The game control device 200 is electrically connected to the start winning device 14, the grand prize device 300, the general winning device 13, the symbol display device 25, the effect display device 100, the operation button 9, the speaker and the lighting device, and various controls are performed.

  The lottery means 226 functions as “special symbol lottery means”. The lottery means 226 includes a lottery value acquisition means 212, a success / failure determination means 213, and a pattern determination means 214. The lottery means 226 as a special symbol lottery corresponding to winning in the start winning device 14 (entering a start winning opening). Execute. The result of the success / failure lottery is shown in the form of a special symbol variation display on the symbol display device 25, and on the effect display device 100 in the form of a decorative symbol variation display. The lottery means 226 transmits the lottery result corresponding to the symbol variation to the effect determining unit 232 when starting the symbol variation.

  The lottery value acquisition unit 212 uses a random number value as a pass / fail lottery value (also referred to as a “special drawing lottery value”) for winning / failing lottery in response to winning at the start winning device 14 (ball entering the start winning port). get. For example, the value acquired as the success / failure lottery value for the success / failure lottery is acquired from a range of values from “0” to “65535”. The “random number” may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The value acquired as the success / failure lottery value is temporarily held by the hold control means 216. However, the success / failure lottery value is held within a range not exceeding the predetermined hold upper limit number held by the hold control means 216.

The success / failure determination means 213 performs the determination of success / failure to determine whether or not to shift to a special game that is more advantageous to the player than the normal game based on the success / failure lottery value. The success / failure determination unit 213 holds a plurality of success / failure tables referred to in the determination of success / failure. In the plurality of success / failure tables, the determination result of big hit / loss and the success / failure lottery value are associated with each other, and the success / failure probability is determined according to the associated winning range setting. The success / failure determination means 213 refers to any of a plurality of success / failure tables according to the gaming state, and determines whether or not the success / failure lottery value is a big hit.

  Based on the separately acquired symbol lottery value and the result of the determination, the success / failure determination means 213 determines the stop symbol of the stop symbol, that is, the special symbol to be displayed at the end of the symbol variation. The success / failure determination means 213 holds a symbol determination table to be referred to in order to determine a special symbol stop symbol. Note that the success / failure determination unit 213 may hold a plurality of symbol determination tables corresponding to a plurality of gaming states, and appropriately switch the reference target table to a table corresponding to the current gaming state.

  When the winning / losing lottery result is a jackpot, the hit / fail determining means 213 selects any one of “1” to “4” as a special symbol stop symbol, that is, a jackpot symbol, with a probability of 1/4. Here, the special symbols “1” and “2” are associated with a special game with 16 rounds, while the special symbols “3” and “4” are associated with a special game with 8 rounds. In addition, special symbols “1” and “3” are associated with a short time, and after the special game is over, the time is shifted to a short time. On the other hand, no special time is associated with the special symbols “2” and “4”, and the special game “2” and “4” are not shifted to the short time after the special game ends. In the present embodiment, the short-time rush rate associated with the winning / failing lottery result being a big hit is 50%. Note that the symbol determination table may determine the correspondence between the success / failure, the symbol lottery value, and the special symbol, and the correspondence between the special symbol, the number of rounds, and the time reduction may be defined in another table.

  The pattern determining means 214 determines a variation pattern in which a symbol variation display process to be displayed on the symbol display device 25 and the effect display device 100 is determined from a plurality of variation patterns based on a separately acquired pattern lottery value. The first pattern determination unit 214 refers to the variation pattern table when starting the symbol variation, and determines the variation pattern of the symbol variation according to the winning / failing lottery result and the stop symbol determination result. The pattern determining unit 214 notifies the effect determining unit 232 of the determined variation pattern, thereby causing the effect determining unit 232 to select an effect pattern corresponding to the variation pattern. The pattern determining unit 214 holds a plurality of variation pattern tables that are referred to for determining the variation pattern.

  The variation pattern defines a variation mode from the variation start to the stop when the special symbol is variably displayed, and has various variation times depending on the type. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol is stopped when the variation display time elapses. For example, the variation pattern includes a pattern corresponding to an effect for removal, a pattern corresponding to a normal reach effect (a pattern for securing a relatively short reach effect time), and a pattern corresponding to a super reach effect (a relatively long pattern). Pattern for ensuring reach performance time), a pattern corresponding to the effect for the big hit notification, a pattern corresponding to the effect for the small hit notification, and the like.

  The hold control means 216 holds the new lottery result until the start of the change display of the symbol corresponding to the lottery when the symbol variation corresponding to the previous lottery is displayed when the lottery is newly executed. To do. The reserved number is represented by the number of lighting or blinking of a special symbol holding lamp provided in the symbol display device 25.

The main display control means 218 includes special figure control means 248. The special symbol control unit 248 causes the symbol display device 25 to display the variation of the special symbol in accordance with the variation pattern determined as a result of the lottery by the lottery unit 226. The special symbol control means 248 sets a new symbol variation start condition that the symbol variation display corresponding to the lottery performed before that time has ended. The special figure control means 248 transmits the fluctuation start command and the fluctuation stop command to the effect display control means 234 at the timing of starting and stopping the fluctuation display of the special symbol. Thereby, the fluctuation display by the main display control means 218 and the effect display control means 234 is synchronized, and the interlock is maintained.

  The condition holding unit 276 includes a special game operation condition holding unit 278. The special game operation condition holding means 278 holds special game operation conditions for shifting to a special game including a plurality of unit games accompanied by opening of the big prize device 300 (large prize inlet 301). The special game operation condition holding means 278 holds, as the special game operation condition, that the lottery result indicates a shift to the special game and the special symbol is stopped in a predetermined big hit mode.

  The special game control means 220 determines that the special game operation condition is established when the special symbol is stopped in a predetermined big hit mode when the result of the lottery means 226 indicates that the winning / losing lottery indicates the transition to the special game. Then, the special game is executed by opening the big prize device 300 (big prize inlet 301).

  The special game is a game in which the opening / closing operation of the grand prize inflow port 301 (sliding door 302) of the grand prize winning device 300 is continuously performed a plurality of times, and is configured by a plurality of unit games with one opening / closing as a unit. The The special game control means 220 opens the grand prize inflow port 301 for about 30 seconds in one unit game. The total opening time (total opening state time) of the grand prize winning entrance 301 in the special game is not less than a predetermined opening reference time (2 seconds in this embodiment) in order to distinguish between the long-term opening game and the short-term opening game. It has become. The special game control means 220 ends the special game when the number of rounds set for the unit game is exhausted.

  The special game control means 220 of the present embodiment is associated in advance with the jackpot symbol determined by the above-described success / failure determination means 213 when the success / failure lottery by the lottery means 226 results in the transition to the special game. A special game with a maximum number of unit games for the number of rounds is executed. That is, when the jackpot symbol is “1” or “2” (50% probability), a 16R special game including 16 unit games is executed, and when the jackpot symbol is “3” or “4” (50% probability). ) 8R special game including 8 unit games is executed.

  The specific game execution means 222 controls the normal game in the short time state, that is, the easy entry state and the specific game state. When the special game based on the special symbol jackpot is completed, the specific game executing means 222 shifts the game state of the normal game to the short-time state according to the jackpot symbol. For example, the specific game execution means 222 may determine whether or not to shift to the short time after the end of the special game with reference to the above-mentioned short time shift determination table that associates the jackpot symbol with the presence or absence of the short time. The time-short state is continued until the total number of times that the special symbol is changed is counted from the end point of the special game to a predetermined number of end conditions, for example, 100 times. Further, the pattern determining means 214 selects a variation pattern having a short variation time so that the variation display time of the special symbol is substantially shortened.

  The opening / closing control means 224 controls the opening / closing operation of the slide door 302 of the special prize winning device 300. In the special game, the opening / closing control means 224 sends an opening instruction to the large winning solenoid 321 to open the slide door 302 of the large winning device 300.

The pattern storage means 230 holds a plurality of effect patterns in which effect image contents to be displayed on the effect display device 100 in the variation of the decorative design and the display process thereof are determined. The effect pattern is displayed separately from the variation display pattern of the decorative design, the change process from the start to the stop of the change and the change process of the effect design, and the display of the decorative design change display of the expectation to the jackpot A plurality of notice effect patterns that suggest the height in advance before stopping the variable display are included.

  The effect determining means 232 determines the contents of effects to be displayed on the effect display device 100 by the effect display control means 234 according to the lottery result received from the lottery means 226. The effect determining unit 232 selects any one of the plurality of variation effect pattern data corresponding to the variation pattern of the special symbol determined by the pattern determining unit 214 and reads it from the pattern storage unit 230. The effect determining means 232 sends the read information on the fluctuation effect pattern to the effect display control means 234. The effect determining means 232 holds a pattern table to be referred to in order to select a variable effect pattern. Each variation effect pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect determining means 232 selects a change effect pattern of effect images having the same change time according to the change pattern of the special symbol.

  The symbol pattern determining means 231 determines the combination and arrangement of the stop symbols of the decorative symbols according to the lottery means 226, the special symbol stop symbol, the special symbol variation pattern, and the decorative symbol variation effect pattern. . The symbol form determination unit 231 transmits information indicating the determined combination of stop symbols to the effect display control unit 234. The symbol form determining means 231 holds a symbol range table to be referred to in order to determine the stop symbol of the decorative symbol.

  The decorative symbol stop symbol is formed as a combination of three symbols. For example, when the success / failure determination result by the success / failure determination means 213 indicates a transition to a special game of 16R big hit or 8R big hit, a specific combination, for example, “777”. ”Or“ 111 ”, a combination of three symbols is selected. If the determination result is not a big hit, a combination that does not have three symbols such as “312” and “946” is selected. When the determination result is not 16R big hit or 8R big hit, and a variation pattern showing a loss with reach is selected, a combination where only one symbol is not complete, such as “191” or “727” Select.

  The decorative symbol variation pattern defines a decorative symbol variation display mode, that is, an effect process from the variation start to the variation stop of the decorative symbol. In the fluctuation pattern, a pattern for displaying a normal out symbol, a pattern for displaying a symbol out of reach after reaching a big win if one more symbols are aligned, and a jackpot symbol through a reach state are displayed. When the pattern is included. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. Each variation pattern has a variation time for each pattern as an end condition of the symbol variation, and the symbol variation is stopped when the variation time elapses. The effect deciding means 232 selects a decorative pattern variation pattern having the same variation time as the special symbol according to the special symbol variation pattern.

  The notice effect pattern is an effect pattern that temporarily displays an image, animation, video, or the like of a specific character or motif, or an effect pattern that outputs a specific sound. The effect by the notice effect pattern is executed in parallel with the symbol variation, and suggests that the symbol variation is highly expected to stop in the big hit mode. For example, there are a normal notice effect in which only one character image is displayed on the screen, and a group notice effect in which a large number of characters are displayed so as to pass from one end to the other end of the screen. Further, the display process of the notice effect is divided into a plurality of stages, and the number of stages to be displayed is made variable, and a step-up notice effect that is set such that the greater the number of stages is, the higher the degree of expectation for the big hit is included. The notice effect pattern includes a pattern in which the effect is executed at the timing after the decorative pattern display mode reaches the reach state, and a pattern in which the final stop mode of the symbol is notified, and a timing at which no decorative symbol is stopped. There is a pattern in which the performance is executed and a reach is reached at the same time.

The effect determining means 232 determines whether or not to display the notice effect on the effect display device 100 according to the result of the success / failure lottery by a predetermined notice lottery, sets the prior effect, and determines the notice effect pattern to be displayed. To do. The effect determining means 232 holds a notice determination table to be referred to in order to determine whether or not to display the notice effect, and a notice type table to be referred to when selecting the type of the notice effect pattern. The notice decision table is set so that different columns are referred to depending on the result of the lottery, and if the lottery is a win, the lottery will be displayed with a higher probability than when it is missed. The correspondence between whether or not to display the result and the notice effect is determined. Thereby, the high expectation degree to the big hit can be suggested by displaying the notice effect itself.

  The effect display control means 234 variably displays the effect image including the decorative pattern on the effect display device 100 according to the selected variation effect pattern data as a result of the success / failure lottery by the lottery means 226. The effect display control means 234 starts a new symbol variation when receiving a decorative symbol variation start command. Further, when the effect determining unit 232 determines that the notice effect is to be displayed, the effect display control means 234 displays the effect in such a manner that the notice effect according to the selected notice effect pattern is superimposed on the effect of the symbol variation. It is displayed on the device 100. The effect display control means 234 further controls effect processing such as lighting and extinguishing of the electrical decoration device and voice output from the speaker.
