  In the above-described ball game machine, for example, a decorative member provided in an accessory is caused to emit light to enhance the visual effect. The present inventor has found a possibility of further enhancing the effect of the ball game machine by devising the structure and effect of the display device.

  An object of the present invention is to provide a ball game machine with enhanced presentation effects in a display device.

  In order to solve the above-described problems, a bullet ball game machine according to an aspect of the present invention includes a game board in which a game area is formed, a start opening provided in the game area, into which a game ball can enter, and a start opening. Lottery means for determining whether or not to generate a special game that is more advantageous to the player than the normal game based on the incoming game balls, a symbol display device that variably displays symbols on the display surface, and a symbol display device A covering member that covers a part of the display surface and is capable of transmitting display light from the display surface. The covering member has a structure that varies the direction of transmitted light from the display surface of the symbol display device. The symbol display device may include a liquid crystal panel.

  According to this aspect, by providing the covering member capable of transmitting the output light from the display surface with a structure that varies the direction of the transmitted light, it is possible to realize an effect different from the transmitted light having the same direction. Therefore, for example, even when an effect is performed such that a simple pattern design is displayed in the area of the display surface covered with the covering member, the direction of the transmitted light of the pattern design that is visually recognized varies, which is different from normal. It becomes visible and it is possible to obtain a high performance effect.

  The structure that varies the direction of transmitted light may be a concavo-convex structure in which concavo-convex is formed inside or on the surface of the covering member. For example, the direction of transmitted light can be varied by forming an uneven structure on the surface (front surface) facing the player. Moreover, when the cover member has an internal space such as a case body, the direction of transmitted light can be varied by providing an uneven structure inside.

  The covering member may form a passage for a game ball. This passage may be formed in the upper part of the covering member, for example. As a result, the covering member has both a function as a game ball passage and an effect function for varying the transmitted light, and the number of parts can be reduced as compared with the case where both functions are configured as separate members.

  The ball game machine may further include display control means for controlling display on the symbol display device. The display control means divides the display surface of the symbol display device into a first area that is not covered by the covering member and a second area that is covered, and performs different effects in each area. Since the appearance of the display contents is different due to the difference in transmitted light direction between the first area and the second area, the characteristic display of each area is utilized by changing the presentation display of each area. Production can be realized.

  The display control means may display the result of the lottery by the lottery means in the first area, and may display a dynamic predetermined pattern symbol in the second area. By presenting information indicating the game contents and game results in the first area not covered by the covering member, it becomes possible to clearly show the player important information to the player. On the other hand, by presenting a pattern or the like in the second region covered by the covering member, for example, it is possible to realize an effect that makes the player enjoy the change in appearance in the concave and convex portions.

  The display control means may display a pattern design in accordance with the positional relationship between the concave and convex portions in the concavo-convex structure in the second region. For example, when taking a structure in which concave portions and convex portions with a predetermined width are arranged in a stripe shape in the vertical direction, the stripe images of two colors with substantially the same interval are moved in the horizontal direction to match the concave and convex structure. Production can be realized.

  This ball game machine is provided in the same object as the symbol display device, and the variable ball entry device capable of changing the accepting state of the game ball to a state advantageous to the player and the ball entering the variable ball entry device are detected. A ball entry detecting device may be further included. The display control means performs effect display in the second area based on the timing at which the game ball enters the variable pitching device. Thereby, it is possible to realize an effect of notifying the player that the game ball has entered the variable pitching device and improving the player's expectation.

  The display control means may perform an effect display in the second area according to the position of the game ball in the accessory provided with the symbol display device. When the upper surface of the covering member constitutes a game ball passage, for example, the effect display in the second area is determined according to the position of the game ball on the game ball passage, thereby realizing the effect in accordance with the game state.

Specifically, the second prize winning opening 30 can be opened and closed by driving and controlling the prize winning solenoid 80, and functions as a second variable pitching apparatus capable of changing the state. To do. The second big prize opening 30 is opened when the game ball enters the ordinary electric accessory 26. When the second grand prize opening 30 is in the closed state, the game ball cannot enter the second big prize opening 30, and the game ball can enter the second big prize opening 30 only when it is in the open state.

  An effect symbol display device 60 and a special symbol display device 61 are provided on a center accessory 64 provided in the approximate center of the game board 50. The special symbol display device 61 displays the special symbol while fluctuating (hereinafter, such display is referred to as “symbol variation” or “variable display”). The special symbol is a symbol corresponding to the result of a lottery performed when a game ball enters the first start port 24, and has a role of indicating whether or not to generate a jackpot. The special symbol display device 61 is display means composed of, for example, LEDs. The effect symbol display device 60 displays the decorative symbol while fluctuating in conjunction with the special symbol variation display. The decorative symbol is a symbol for visually producing a lottery result display indicated by a special symbol. The effect symbol display device 60 displays, as a decorative symbol, for example, a plurality of rows of symbol variation moving images simulating a slot machine game in the central area of the screen. The effect symbol display device 60 is configured by a liquid crystal display in this embodiment, but may be configured by other display means such as a mechanical drum or LED.

  In addition, since it is not necessary for the special symbol to have a role of production, the special symbol is displayed in an inconspicuous size on the special symbol display device 61 in this embodiment, but the special symbol itself has a role of production and is a decorative symbol. In the case of adopting a technique that does not display the special symbol, the special symbol may be displayed on a liquid crystal display such as the effect symbol display device 60.

  In the center accessory 64 of the present embodiment, the effect symbol display device 60 is covered with a covering member capable of transmitting display light from the display surface at a part below the display surface. For example, the covering member is configured as a stage unit provided in the center accessory 64. The covering member has a structure in which the direction of transmitted light from the effect symbol display device 60 is varied, and this structure is configured by forming irregularities inside or on the surface of the covering member, for example. For example, the unevenness may be given a predetermined angle with respect to the viewing direction from the player, and the direction of transmitted light may be varied by this angle. Thereby, a part of transmitted light can be blurred, and a new effect can be realized.

  The concavo-convex structure is formed, for example, as a pattern carved on the front surface of the covering member facing the player. Instead of configuring the surface of the covering member flat, by configuring it as a cutout pattern with physical unevenness, for example, even if there is no change in the effect, decorate the gaming machine with the pattern itself, In the case where an effect by liquid crystal display is performed, a new effect that has not been achieved can be realized by varying the transmitted light of the light at the notch.

  The center accessory 64 is provided with a holding lamp for changing special symbols. The reserved lamp for special symbol variation consists of four lamps, and the number of reserved balls for special symbol variation is displayed according to the number of lights. The number of reserved balls is the number of lottery random numbers won to the first start port 24 during the special symbol variation, and indicates the number of winning balls for which the special symbol variation has not yet been executed. Similarly, the center accessory 64 is provided with a holding lamp for normal symbol variation. This holding lamp is also composed of four lamps, and the number of holding balls of normal symbol variation is displayed according to the number of lights. The number of reserved balls is the number of lottery random numbers that have entered the second starting port 68 during normal symbol variation, and indicates the number of balls that have not yet been subjected to normal symbol variation. In FIG. 1, the holding lamp is not shown.

  When the player turns the launch handle 17 by hand, the game balls stored in the upper ball tray 15 are guided one by one to the inner rail 56 and the outer rail 54 with a strength corresponding to the turning angle, thereby playing the game area. To 52. When the player fixes the rotation position of the firing handle 17 by hand, the game ball is repeatedly fired at regular time intervals. The game ball launched to the upper part of the game area 52 falls in a direction according to the way of hitting while hitting a plurality of game nails and windmills. When a game ball falls into each of the winning openings such as the first starting opening 24, the ordinary electric accessory 26, the second large winning opening 30, the first large winning opening 28, etc., the winning ball corresponding to the type of the winning opening is raised. The ball tray 15 or the lower ball tray 16 is paid out. A game ball dropped into each winning port such as the first start port 24 is processed as a safe ball, and a game ball dropped into the out port 58 is processed as an out ball. Each winning opening includes a gate type through which a game ball passes, and “entering ball” includes “incoming”, “winning”, and “passing”.

  When the game ball falls into the first start port 24, the special symbol and the decorative symbol are variably displayed on the special symbol display device 61 and the effect symbol display device 60. The variation display of the special symbol and the decorative symbol is stopped after the lapse of the variation time determined prior to the display. When the special symbol at the time of the stop is a symbol indicating a big hit, the opening / closing operation of the first big winning opening 28 is started, and a transition is made to a special game which is a game state advantageous to the player over the normal game. In this embodiment, the special game that is executed when the special symbol stops at the jackpot symbol is referred to as a “first special game”. When the special symbol is stopped at the jackpot symbol, the decorative symbol imitating the game of the slot machine takes a display mode in which three symbols are matched. In the first special game, the first grand prize opening 28 is temporarily closed after being opened for about 30 seconds or after nine or more game balls are dropped. The first special game is composed of one or more unit games. The number of unit games is a maximum of 15 times, and is determined by lottery every time the first special game occurs. Since one opening / closing operation is performed in one unit game, the opening / closing operation of the first big prize opening 28 is repeated for the number of unit games.

  After the end of the first special game, a specific game with a predetermined number of symbol variations is started. The specific game may take a game mode different from the so-called jackpot game, and may take a game mode in which the variation time of the special symbol and the decorative symbol is shortened. In this embodiment, one of the start conditions for the specific game is set to end the first special game. The maximum number of variations of special symbols and decorative symbols in a specific game is set to a predetermined number of times, for example, 35 times from the start of the specific game. When the symbol variation of special symbols and decorative symbols reaches 35 times, the specific game ends. The specific game ends when the condition is satisfied. In normal times, the time of the symbol variation of special symbols and decorative symbols is set to 10 seconds, 30 seconds, 1 minute, etc., but the time of symbol variation of special symbols and decorative symbols during a specific game is uniform. Reduced to 6 seconds. Therefore, many special symbols and decorative symbols can be changed in a relatively short time. In this embodiment, the example of shortening the time of the symbol variation of the special symbol and the decorative symbol during the specific game to 6 seconds is shown, but it is not intended to limit the number of seconds such as 6 seconds, but compared with the normal state. As long as the time is shortened, it is enough.

  When the game ball passes through the second starting port 68, a symbol called a normal symbol is variably displayed for a predetermined time. The normal symbol is variably displayed at the lower right corner of the screen of the effect symbol display device 60. Note that the normal symbol may be variably displayed on another display device. When the normal symbol is displayed on the effect symbol display device 60, the effect symbol display device 60 also functions as a normal symbol display device. The normal symbol variation display is stopped after a lapse of a predetermined time, and the normal electric accessory 26 is released for a predetermined time when the normal symbol is stopped at the predetermined symbol.

  When a game ball falls into the opened ordinary electric accessory 26, the second big prize opening 30 is opened upon the entry, and a transition is made to a special game that is a game state that is more advantageous to the player than the normal game. To do. A special game that is executed when a game ball enters the ordinary electric accessory 26 is referred to as a “second special game”. The state in which the second big prize opening 30 is opened in the second special game is called the first stage of the second special game.

  A specific area 256 and an outflow area are provided inside the second big prize opening 30. The inside of the center accessory 64 is formed so that a game ball flows in through the opened second big prize opening 30, and the game ball that has flowed into the center accessory 64 is a specific region 256, an outflow region or a center accessory. 64 falls to one of the outside. A ball entering the opened second big prize opening 30 is detected by the ball entry detecting device 81, and the total number of balls entered into the opened second big prize opening 30 is counted. A guidance device 62 that guides the game ball that has flowed in from the second grand prize opening 30 to either the specific area 256 or the outflow area is further provided inside the center accessory 64. The guiding device 62 includes two rotating bodies each having a plurality of rotating blades. These two rotating bodies are always rotating, and when the long rotating blades come close to each other, the game balls that have dropped onto them are guided to the specific area 256. When the long rotating blades are not close to each other, the game ball that has fallen onto it enters the outflow area.

  The entrance to the specific area 256 is detected by the entrance detection device 36. When the game ball enters the specific area 256, the transition condition from the first stage to the second stage of the second special game is established, and thereafter, as in the first special game, the second special game As two steps, the opening / closing operation of the first grand prize opening 28 is repeated for the remaining number of unit games. That is, the second special game is also composed of one or more unit games, and the number of unit games is set to ten. The first stage of the second special game corresponds to the first unit game, and the second stage corresponds to the second and subsequent unit games. From the second time on, the opening / closing operation is performed once in one unit game, and the opening / closing operation of the first big prize opening 28 is repeated for the remaining number of unit games. In the present embodiment, the number of times of opening and closing the first big prize opening 28 in the first special game is 15 times, whereas the number of times of opening and closing the first big prize opening 28 in the second special game is nine times. Note that the completion of the second stage of the second special game may be set as a start condition for the specific game. In this case, when the second stage of the second special game is completed, the specific game in which the second special game is likely to occur is started again.

  In the pachinko gaming machine 10 of the present embodiment, by using the same first grand prize opening 28 as a variable pitching device that executes continuous state changes in the first special game and the second special game, The space above 52 can be used effectively. In addition, by using a common variable pitching device that continuously changes its state, it is possible to simplify the operation control of the special game, and to reduce the manufacturing cost.

The game control device 100 controls not only the basic operation of the game, but also staging operations such as symbol variation display and electrical decoration. The game control device 100 may be configured in such a manner that the functions are shared by the main board 41 that controls the overall operation of the pachinko gaming machine 10 including the basic operation of the game, and the sub board 49 that controls the production of symbols and the like. Good.

  The game control device 100 is configured by hardware including elements such as a ROM and a RAM for storing data and programs, and a CPU used for arithmetic processing. The game control apparatus 100 according to the present embodiment is a first lottery that executes special symbol lottery based on the incoming ball judging means 110 that determines whether or not the ball has entered the first entrance 24 and the first starting port 24. Means 112, second lottery means 114 for executing a normal symbol lottery based on a game ball entering the second starting port 68, pattern storage means 116 for holding a special symbol, a decorative symbol, a normal symbol variation display pattern, a variation Winning storage means 117 for storing the ball entering each starting port during the display as a holding ball within the upper limit number, symbol determining means 120 for determining a symbol variation stop symbol and a variable display display pattern, symbol or illumination, etc. Display control means 130 for controlling the display of the game, special game control means 140 for controlling a special game that is more advantageous to the player than a normal game such as a jackpot game, a reduction in symbol variation time and a probability variation in the normal symbol lottery Specific game control means 160 for controlling a specific game advantageous to the player over the normal game, and a variable entrance or variable for changing the state of accepting the game ball between a state advantageous for the player and a disadvantageous state And an opening / closing control means 170 of the ball entry device.

  When a game ball enters the first start port 24 during the special symbol variation display by the first display control unit 131, the prize storage unit 117 can select up to four lottery results corresponding to the ball. When a game ball enters the second start opening 68 during the normal symbol variation display by the first storage means 118 and the second display control means 132 stored as a holding ball, the lottery result corresponding to the entered ball is the upper limit. And second storage means 119 for storing up to four as the number of reserved balls.

  The ball entry detection device 32 is a sensor provided in the first start port 24, detects the drop of the game ball into the first start port 24, and generates first start winning information indicating the drop. Upon receiving the first start winning information, the entering determination unit 110 determines that the game ball has entered the first start port 24. When it is determined that a ball enters the first start port 24, the first lottery means 112 checks whether or not the number of held balls has reached the upper limit. For example, the upper limit of the number of reserved balls is preset to four. When the number of reserved balls has not reached the upper limit, the first lottery unit 112 acquires a random number for the start winning at the timing when the entering determination unit 110 receives the first start winning information. The first lottery means 112 may mathematically generate and acquire a random number, or may acquire a count value generated by a counter (not shown) as a random number. The first lottery means 112 determines whether or not the special symbol lottery is successful based on the acquired random number. Note that the determination of whether or not the lottery is successful may be performed together with the acquisition of a random number, or may be performed immediately before starting the change of the special symbol.

  The special symbol determining unit 122 and the decorative symbol determining unit 124 in the symbol determining unit 120 determine a stop symbol corresponding to the determination result by the first lottery unit 112 and a display pattern of symbol variation. The stop symbol is a symbol to be displayed at the end of symbol variation. The pattern storage means 116 holds a plurality of types of patterns as display patterns for variably displaying special symbols and decorative symbols. In the display 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 addition, patterns having various display times are included as patterns in the reach state. As each of these patterns, a normal display pattern having a normal variation time and a special display pattern for a specific game whose variation time is shorter than normal are stored in the pattern storage unit 116. In the case of a normal display pattern, for example, a pattern for 10 seconds is stored as a pattern for displaying a normal out symbol, and a pattern for 30 seconds or one minute is displayed as a pattern for displaying a dismiss symbol or a jackpot symbol through a reach state. Stored. In the case of a special display pattern, for example, a short pattern of 6 seconds is stored regardless of whether it is off or hit. When the display time determined by each display pattern elapses, the symbol variation ends at the stop symbol.

  The special symbol determination means 122 selects any pattern from the pattern storage means 116 according to the lottery result by the first lottery means 112, and determines the special symbol stop symbol according to the lottery result. The decorative symbol determination unit 124 selects a pattern corresponding to the display pattern selected by the special symbol determination unit 122 from the pattern storage unit 116, and determines a stop symbol of the decorative symbol according to the lottery result. The decorative symbol determination means 124 determines a jackpot symbol in which three identical numbers are arranged in the case of a jackpot. The decorative symbol determination means 124 determines the pattern symbol to be displayed in the area covered with the transparent covering member in the effect symbol display device 60. This pattern symbol is stored in the pattern storage means 116 as a decorative symbol.

  Here, in the normal game, the special symbol determining unit 122 and the decorative symbol determining unit 124 select the normal display pattern, but in the specific game, select the special display pattern. Since the special display pattern is a pattern of 6 seconds shorter than the normal display pattern, the digestion time of the reserved ball is advanced. In addition, the pattern symbol displayed in the area | region covered with the covering member in the effect symbol display apparatus 60 may be determined irrespective of a normal game or a specific game.

  The incoming ball detecting device 38 is a sensor provided in the second starting port 68, detects the falling of the game ball into the second starting port 68, and generates second starting ball entering information indicating the falling. When receiving the second start entry information, the entry determination unit 110 determines that the game ball has entered the second start port 68. When it is determined that a ball enters the second starting port 68, the second lottery means 114 checks whether or not the number of balls to be held has reached the upper limit. For example, the upper limit of the number of reserved balls is preset to four. When the number of held balls has not reached the upper limit, the second lottery unit 114 obtains a random number for the starting pitch at the timing when the pitch determination unit 110 receives the second starting pitch information. The second lottery means 114 may mathematically generate and acquire a random number, or may acquire a count value generated by a counter (not shown) as a random number. The second lottery means 114 determines whether or not the normal symbol lottery is successful based on the acquired random number. Note that the determination of whether or not the lottery is successful may be performed together with the acquisition of a random number, or may be performed immediately before starting the change of the normal symbol.

  The normal symbol determining unit 126 selects one of the patterns from the pattern storage unit 116 according to the lottery result by the second lottery unit 114, and determines the stop symbol of the normal symbol according to the lottery result. When the stop symbol determined by the normal symbol determining unit 126 is a specific symbol, the opening / closing control unit 170 expands the normal electric accessory 26 that is a variable entrance for a predetermined time. The pattern storage means 116 stores, as a normal symbol display pattern, a normal display pattern having a normal variation time and a special display pattern for a specific game whose variation time is shorter than normal. A pattern for 30 seconds is stored as a normal display pattern, and a pattern for 6 seconds is stored as a special display pattern. The symbol variation of each display pattern is stopped when the display time defined as the symbol variation end condition has elapsed.

  The display control unit 130 includes a first display control unit 131 that displays a special symbol and a decorative symbol in a variable manner, and a second display control unit 132 that displays a normal symbol in a variable manner. The first display control unit 131 causes the special symbol display device 61 to display the special symbol based on the display pattern and the stop symbol selected by the special symbol determination unit 122. At the same time, the first display control unit 131 displays the decorative symbols on the effect symbol display device 60 based on the display pattern and the stop symbol selected by the decorative symbol determining unit 124. In the pachinko gaming machine 10 of the present embodiment, the first display control means 131 divides the display surface of the effect symbol display device 60 into a main region and a sub region, and displays a decorative symbol in the main region, while in the sub region Display a pattern such as a stripe pattern. The function of displaying a special symbol by the first display control means 131 is executed as a process on the main board 41 side, and the function of displaying a decorative symbol or a pattern symbol is executed as a process on the sub board 49 side. The second display control unit 132 displays the normal symbol on the effect symbol display device 60 based on the display pattern and the stop symbol selected by the normal symbol determining unit 126. The display control means 130 also controls lamp displays such as game effect lamps and hold lamps.

  In this embodiment, the special game control means 140 can selectively execute two types of special games. In the special game control means 140, the condition holding means 142 holds operating conditions for two types of special games. The special game execution means 148 has a function of executing a special game on the basis that a predetermined operating condition is established.

  The first condition holding means 143 holds a first operating condition that is a condition for executing the first special game. The first operating condition is set such that the special symbol variably displayed by the first display control means 131 is stopped at a predetermined symbol in the special symbol display device 61. The second condition holding means 144 holds a second operation condition that is a condition for executing the second special game. The second operating condition is set so that the game ball falls into the ordinary electric accessory 26. The condition determination means 146 monitors the game situation and determines whether the first operation condition or the second operation condition, which is a condition for shifting to the special game, can be established. The condition determination means 146 sets various operation flags on or off based on the determination result of each operation condition.

  The special game execution means 148 executes a special game when any of the operating conditions is satisfied. The first special game execution means 149 executes the first special game when the first operation condition is satisfied, and the second special game execution means 150 executes the second special game when the second operation condition is satisfied. The operation avoiding means 152 has a function of avoiding the establishment of the other operation condition when one of the first operation condition and the second operation condition is satisfied. The second special game is executed as a game divided into two stages of the first stage and the second stage, and the establishment of the second operation condition is that the condition for transition to the first stage of the second special game is established. It is assumed that the second operating condition is established as long as the second special game continues through the first stage and the second stage. Therefore, the establishment of the first operation condition is avoided while the second operation condition is being established and the first stage or the second stage of the second special game is being executed. On the other hand, since the establishment of the second operation condition is avoided while the first operation condition is established, neither the first stage nor the second stage of the second special game is executed.

  The specific game control means 160 executes a specific game advantageous to a player different from the special game, for example, control of symbol variation time and control of probability variation of normal symbols. Specifically, the specific game control means 160 shortens the symbol variation time of each of the special symbol, the decorative symbol, and the normal symbol. Further, the specific game control means 160 sets the opening time of the ordinary electric accessory 26 to be long and sets the number of opening times to be large.

  The specific game control means 160 controls execution of a specific game with a predetermined number of symbol fluctuations when a predetermined specific game start condition is satisfied. In this embodiment, the specific game start condition includes a condition that the second stage of the first special game or the second special game is completed. In this case, the specific game is always executed when the second stage of the first special game or the second special game ends. It may be set as a specific game start condition that the special symbol stops at a predetermined symbol and the first special game is ended. This predetermined symbol may be an odd symbol, for example. Further, as a result of the lottery performed by the second lottery means 114, it may be set as a specific game start condition that a symbol called a determination symbol has stopped in a specific manner. The specific game control means 160 includes a first specific game execution means 162 that controls the change display of the special symbols and decorative symbols by the first display control means 131 during the specific game, and a normal display by the second display control means 132 during the specific game. And a second specific game execution means 164 for controlling the symbol display and the lottery process by the second lottery means 114. The first specific game execution means 162 and the second specific game execution means 164 execute the specific games when the specific game start condition is satisfied. In the specific game, the number of symbol variation display by the first display control means 131 is set. When the specific game is executed a predetermined number of times, the specific game is terminated and the normal game is started. Note that if the first operation condition or the second operation condition is newly established before the number of symbol variation displays by the first display control means 131 reaches a predetermined number, the specific game is terminated at that time.

  When the specific game start condition is satisfied, the first specific game executing means 162 controls the variation display of the special symbol and the decorative symbol by the first display control means 131 to be shortened. The first specific game execution means 162 returns the variation display time of the special symbol and the decorative symbol to the normal time when the number of variations of the special symbol reaches a predetermined number. When the specific game start condition is satisfied, the second specific game executing means 164 controls the second display control means 132 so that the fluctuation display of the normal symbol is shortened, and the normal lottery probability by the second lottery means 114 is set. increase. During the specific game, the second specific game executing means 164 continuously opens and closes the ordinary electric accessory 26 when the normal symbol stops at the specific symbol, and continuously opens and closes for a plurality of times, that is, for 3 seconds. Switch to a two-time action. The second specific game execution means 164 returns the normal symbol fluctuation display time to the normal time when the number of fluctuations of the special symbol reaches a predetermined number, and sets the probability of winning the normal symbol to the probability before the fluctuation. return.

  During the normal game, the determination table referred to by the second lottery means 114 is set as the non-probability change table, and during the specific game, the determination table is set as the probability change table. The hit ratio of the probability change table is set higher than the hit ratio of the non-probability change table. The second specific game executing means 164 changes the length of the change period of the ordinary electric accessory 26 while executing the probability variation of the ordinary symbol. For example, the ordinary electric accessory 26 is opened for a relatively long time of 3 seconds during the probability variation of the ordinary symbol. This makes it easier for a game ball to enter than during a normal game, so that the second special game is more likely to occur during probability fluctuations.

The content displayed in the main area is a decorative pattern imitating the slot machine, and the content displayed in the sub area is, for example, a red and white stripe pattern or a pattern pattern expressing color change in gradation.

  In the sub region, the direction of transmitted light from the display surface varies due to the notch pattern provided on the front surface of the second stage portion 261. It is preferable to clearly present to the player an effect that expresses the game content such as the result of the lottery. Therefore, the result of the lottery is displayed in the main area to improve the player's visibility. On the other hand, for example, a pattern such as a red and white stripe pattern does not represent game content, and visibility is not required. Therefore, such a symbol is displayed in the sub area.

FIG. 12 shows an example of the uneven structure in the second stage portion. FIGS. 12A to 12C are cross-sectional views of the front surface of the second stage portion 261. FIG. In addition, although the following uneven | corrugated structure is formed in the up-down direction of the front surface of the 2nd stage part 261, for example, it may be formed in a horizontal direction or a diagonal direction.
FIG. 12A shows an uneven structure in which a rectangular groove is formed on the front surface of the second stage portion 261. It is preferable that the groove portion has a slight inclination with respect to the visual recognition direction. As a result, the output light from the effect symbol display device 60 is transmitted through the inclined surface, and the direction of the transmitted light can be suitably varied. be able to. The groove portions are arranged at a predetermined interval.
FIG. 12B shows a concavo-convex structure in which a convex portion having a predetermined curvature is formed on the front surface of the second stage portion 261. Since the transmitted light from the convex portion has a radial spread according to the curvature, a new effect can be realized. The convex portion is formed to extend in the vertical direction on the front surface of the second stage portion 261. The convex portions are arranged at a predetermined interval.
FIG. 12C shows an uneven structure in which a triangular protrusion (projection) is formed on the front surface of the second stage portion 261. The triangular protrusions are arranged at a predetermined interval. By forming the convex portion in a triangular shape, the change in the direction of transmitted light can be made remarkable.

  The 1st display control means 131 may display the pattern design matched with the positional relationship of the recessed part and convex part in a concavo-convex structure in a sub area | region. As shown in FIG. 12, the convex portions (concave portions) are arranged at a predetermined interval, and the first display control means 131 displays the two-color striped pattern color arranged at substantially the same interval as the sub-region. By dynamically displaying the display, it is possible to realize an effect display that matches the uneven structure. For example, the pattern symbol is displayed so as to move from the left to the right as viewed from the player. As a result, despite the fact that a simple pattern design is generated in terms of software, the visibility of the pattern design changes from moment to moment according to the movement position, so that a moving image with a complicated pattern is produced and displayed. A feeling can be given to the player.
