Description

  The present invention relates to a gaming machine such as a pachinko machine provided with a display device capable of variably displaying symbols involved in a game.

  Conventionally, as a kind of gaming machine, a pachinko machine having a variable display device for variably displaying a plurality of types of symbols (numerical symbols) in a predetermined arrangement is known.

  In this type of pachinko machine, according to the display pattern (stop pattern) at the time of variable display stop on the display device, after passing through the reach state, it becomes a “special gaming state” that becomes advantageous to the player, after passing through the reach state An “out-going reach state” that does not become a special gaming state, or an “out-going state” that does not go through a reach state and does not become a special gaming state is generated. The stop symbols include a special game symbol for generating a special game state, a release reach symbol for generating a release reach, and a release symbol for generating a release state.

  In the pachinko machine as described above, the game situation that changes in accordance with the player's operation satisfies a predetermined condition (for example, a game ball wins an operating slot). The change display of is started. Further, a stop symbol corresponding to the game situation is selected from the special game symbol (big hit symbol), the missed reach symbol, and the missed symbol. Then, the variable display is stopped at the selected stop symbol. In this case, the special gaming state described above is generated on the condition that the stop symbol is a predetermined specific symbol (for example, a jackpot symbol such as “7”, “7”, “7”, etc.). More specifically, the big prize opening is opened for a predetermined time, and when the game is opened, a lot of prize balls are paid out to the player by winning the game balls at the big prize opening.

  By the way, in recent years, it has become possible to improve the interest of players by performing display control of colorful identification symbols using a liquid crystal display or the like. More specifically, not only the above-mentioned numerical symbols but also those in which background symbols are displayed as if there is a background (scenery) behind them are becoming known.

  However, in the above-described prior art, the background symbol is only displayed in a stopped state or corresponds to the variation of the numeric symbol at best, compared with the numerical symbol (which can constitute a jackpot symbol or the like) subjected to variable display control. It was just scrolling slowly at a constant speed as if the scenery was moving. For this reason, the presence of the background design merely gives the player the impression that it is beautiful, and it has not been sufficient in terms of achieving a dramatic improvement in interest.

  The present invention has been made in view of the above-described problems, and its purpose is to dramatically improve the interest of a gaming machine such as a pachinko machine equipped with a display device capable of variably displaying symbols related to the game.

  Hereinafter, an embodiment in which a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) is embodied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the game board 2 of the pachinko machine 1 is provided with an operation port 3 and a prize winning port 4. The operation port 3 includes a passage for the game ball 5, and a blade 6 is supported at the passage entrance so as to be opened and closed. A V zone is provided on the right side of the back of the big prize opening 4 and a winning path is provided on the left side (not shown. Alternatively, the left and right sides may be reversed). Then, the game ball 5 which has won the grand prize opening 4 is guided to a winning ball processing apparatus (not shown) through either the V zone or the winning path. A shutter 11 is provided in front of the special winning opening 4. The shutter 11 is actuated by a special prize opening solenoid 12 provided on the side of the special prize opening 4 to open and close the special prize opening 4. Specifically, when the solenoid 12 is in an excited state, the shutter 11 is inclined substantially horizontally, thereby opening the special winning opening 4. Further, when the solenoid 12 is in a non-excited state, the shutter 11 is in a substantially vertical state, whereby the special winning opening 4 is closed.

  A special symbol display device (hereinafter simply referred to as “display device”) 13 is incorporated in the central portion of the game board 2. The display device 13 includes a display unit 13a composed of a liquid crystal display (LCD), on which a plurality of special symbol rows are displayed. As shown in FIG. 2, in the present embodiment, three symbol sequences of an upper symbol sequence 14, a middle symbol sequence 15, and a lower symbol sequence 16 are displayed as these symbol sequences. May be displayed. A background screen or the like is appropriately displayed on the display unit 13a.

  As shown in FIGS. 2 and 3, each of the special symbol rows 14 to 16 is basically composed of a plurality of types of symbols 17A to 17H and a single type of symbols 17K. Each of the symbols 17A to 17H is configured by a combination of various “dog” symbols DG1 to DG8 and “1” to “8” numeral symbols N1 to N8. The numbers “1” to “8” are arranged in descending order for the upper symbol row 14, and in ascending order for the middle symbol rows 15 and 16, respectively. More specifically, the symbol 17A is configured by a combination of a numerical symbol N1 of “1” and a graphic symbol DG1 of “Doberman”. In addition, the symbol 17B is a numerical symbol N2 of “2” and a graphic symbol DG2 of “Dachshund”, the symbol 17C is a numerical symbol N3 of “3” and a graphic symbol DG3 of “poodle”, and the symbol 17D is a numerical symbol of “4”. N4 and “Old Sheepdog” symbol DG4, symbol 17E is “5” numeric symbol N5 and “Tosa Inu” symbol DG5, symbol 17F is “6” numeric symbol N6 and “terrier” symbol DG6, The symbol 17G is constituted by a combination of a numerical symbol N7 of “7” and a graphic symbol DG7 of “Bulldog”, and a symbol 17H is a combination of a numerical symbol N8 of “8” and a graphic symbol DG8 of “St. Bernard”. These symbols 17A to 17H can be any one of the jackpot symbol, the missed reach symbol, and the missed symbol as special game symbols (these will be described later), and constitute a special symbol for determining whether or not the jackpot state occurs. To do.

  The symbol 17K is constituted by a “heart” mark, and is arranged between the symbols 17A to 17H. Furthermore, the symbol 17K can only be an outlier symbol.

  As shown in FIG. 4, in each of the symbol rows 14 to 16, the symbols 17 </ b> A to 17 </ b> H and 17 </ b> K displayed on the near side of the meadow (background symbols: which will also be described later) are from right to left. It is displayed as if it runs through.

  In the display unit 13 a of the display device 13, the symbol variation (rotational variation) of each symbol row 14 to 16 is started based on the winning of the game ball 5 to the operation port 3. Also, one of the jackpot symbol, the missed reach symbol, and the missed symbol is selected and set as a stop symbol. The stop symbol is a symbol displayed when each symbol row 14 to 16 stops symbol variation. In the present embodiment, the symbol variation is stopped in the order of the upper symbol row 14, the lower symbol row 16, and the middle symbol row 15, but this is only an example, and it should be stopped in a different order. Also good. In the case of the stop, the lower symbol row 16 may be temporarily stopped at a higher speed than before and may be suddenly stopped (so-called “slip”).

  5 and 6 are diagrams showing a big hit screen on the display unit 13a. As shown in the figure, the jackpot symbol is a symbol for generating a jackpot state as a special gaming state advantageous to the player after the reach gaming state (reach state). Specifically, when the variation of all the symbol rows 14 to 16 is stopped, the combination of the displayed symbols 17A to 17H is a predetermined jackpot combination, that is, the same type of symbols 17A to 17H is a jackpot. In some cases, the patterns 17A to 17H are combined when lined up along the lines L1 to L5. The symbol constituting this combination is the “big hit symbol”.

  In this embodiment, left and right vertical lines L1 and L2 (see FIGS. 5A and 5B), a central vertical line L3 (see FIG. 6A), and two diagonal lines L4 and L5. (See FIG. 6B), the jackpot line L is configured (referred to as 5 lines). When the jackpot combination is established, the special electric accessory is activated (the jackpot 4 is opened), and it is possible to obtain a jackpot state that is advantageous to the player, that is, to obtain more prize balls.

  Further, as shown in FIGS. 7A to 7D, the reach state means a state immediately before the big hit (of course, the big hit state may not be reached). The reach state includes a state in which the symbol variation of the lower symbol row 16 stops at the same kind of symbols as the stop symbol of the upper symbol row 14 on the jackpot lines L1 to L5. For example, in the example shown in FIG. 7A, on the jackpot line L1, the upper symbol row 14 and the lower symbol row 16 are stopped at the same symbol 17A, and the symbols 17A to 17H and 17K of the middle symbol row 15 are not yet processed. The state during the change is shown. In this case, the jackpot state is generated on the condition that the stop symbol on the jackpot line L1 of the middle symbol row 15 is the symbol 17A.

  In the above reach state, the symbol variation in the middle symbol row 15 will eventually stop at the same kind of symbol (big hit symbol) as the stop symbols in both the upper and lower symbol rows 14 and 16 and become a big hit state Also included are those that stop at different types of symbols (this is referred to as “outgoing reach design”) and do not become a big hit state (hereinafter referred to as “outgoing reach state”). Furthermore, after the symbol variation of the middle symbol row 15 is temporarily stopped, all the symbol rows (or some of the symbol rows) are changed again, and thereafter the symbols 17A to 17H and 17K of all the symbol rows 14 to 16 are stopped. (Also referred to as re-variable reach).

  In the reach state, various reach patterns are set. As the reach pattern, in addition to the “normal reach” in which the symbols 17A to 17H and 17K in the middle symbol row 15 are simply scrolled, as shown in FIG. 5, a character is displayed as “Dragon Reach” (FIG. 7A). "See"), "Log reach (see Fig. 7 (b))" where rivers and logs are displayed, "Ice reach (see Fig. 7 (c))" where ice is displayed on the background screen, and girls displayed as characters “Girl reach (see FIG. 7D)” is set. Among these reach patterns, reach patterns other than “normal reach” are so-called “super reach”. When the operation of “super reach” is started, the expected value (expected value for jackpot) at which a big hit state occurs is higher than in the case of “normal reach”. Also, in “Super Reach”, the expected value of jackpot varies depending on each reach pattern (for example, “Girl Reach” has a higher expected value of jackpot than “Dorbo Reach”).

  Although it has already been described that the symbol variation of each symbol row 14 to 16 is started based on the winning of the game ball 5 to the operation port 3, when the game ball 5 further wins the operation port 3 during this variation display In this case, the corresponding change display is performed after the end of the current change display. That is, the variable display is waited (held). The maximum number of variable displays to be held is determined for each model of pachinko machine. In the present embodiment, the maximum number of holds is set to 4 times, but is not limited to this.

  As shown in FIG. 1, in the display device 13, holding lamps 18a, 18b, 18c, and 18d made of light emitting diodes (LEDs) are incorporated above the display unit 13a. The number of the holding lamps 18a to 18d is the same as the above-described maximum holding number (in this case, four). The hold lamps 18a to 18d are turned on every time the variable display is held, and are turned off when the variable display corresponding to the hold is executed. In addition to this, various lamps for enhancing the gaming effect are attached to a plurality of locations of the pachinko machine 1. These lamps can be turned on (turned off, turned on, blinked, etc.) as the game progresses. Furthermore, the pachinko machine 1 is provided with a speaker (not shown) that generates sound effects as the game progresses.

  In this embodiment, in order to detect the gaming state of the pachinko machine 1 that changes in accordance with the player's operation, the game board 2 includes an operating port switch 21, a V zone switch 22, a count switch 23, and the like. Installed. The operating port switch 21 detects winning of the game ball 5 to the operating port 3, and the V zone switch 22 detects winning of the game ball 5 in the V zone of the large winning port 4, and the count switch 23 Detects the winning of the game ball 5 to the big winning opening 4.

  In the present embodiment, a control device for driving and controlling each of the winning prize solenoid 12, the display device 13 (display unit 13a), the holding lamps 18a to 18d, the speaker, and the like based on the detection results of the switches 21 to 23. 24 is provided. As shown in FIG. 9, the control device 24 includes a main substrate 61, a display device control substrate 62, and the like. The main board 61 is mounted in a sealed state in a board box (not shown) on the back side of the pachinko machine 1. The display device control board 62 is incorporated in the special symbol display device 13.

  The main board 61 of the control device 24 includes a central processing unit (CPU) that is a calculation means, a read-only memory (ROM) that stores various control programs, and a random access memory (RAM) that stores various data. (Both not shown). The RAM is provided with a command buffer and a command counter. The command buffer is a buffer for temporarily storing control data. The control data of the command buffer is updated by a display data creation process executed based on a predetermined trigger, and is output (transmitted) to the display device control board 62 and eventually the display unit 13a by a timer interrupt process. The command counter is a counter indicating the number of control data transmitted to the display device control board 62 by the timer interrupt process. The control data written in the command buffer is transmitted to the display device control board 62 byte by byte by one timer interrupt process. A command counter indicates the number of the transmitted control data.

  The RAM also includes a random number counter for determining the occurrence of jackpots. This random number counter is updated by one count every 2 ms, for example, within a predetermined range (for example, “0” to “199”) by random number update processing. In the present embodiment, when the value of the random number counter is “7”, for example, the game ball 5 wins the operating port 3 and is detected by the operating port switch 21 (except for the maximum number of times of holding). ), The jackpot state is generated.

  These CPU, ROM, and RAM are connected to each other via a bus line. The bus line is also connected to an input / output port (not shown) of the main board 61. The input / output port is connected to the input / output port 75 of the image controller 74 of the display device control board 62 and other input / output devices via a connector and a cable. Of course, the input / output port of the main board 61 is connected to the operation port switch 21 and the like via a connector. That is, the main board 61 of the control device 24 is connected to the display device control board 62 or other input / output device via the input / output port based on a winning signal or the like input from the operation port switch 21 or the like via the input / output port. Various operation commands such as control data are sent to (including other substrates) to control each device.

  In addition to the display unit 13a described above, the display device control board 62 includes an image controller including a CPU 63, a program ROM 64, a work RAM 65, video RAMs 66 to 72, a character ROM 73, and an input / output port 75. 74. The CPU 63 of the display device control board 62 controls the display of the display unit 13a according to the control data transmitted from the main board 61, and the program executed by the CPU 63 is stored in the program ROM 64. Yes. The work RAM 65 stores work data used when the CPU 63 executes the program.

  The video RAMs 66 to 72 are memories for storing data displayed on the display unit 13a. By rewriting the content of the video RAM 66, the display content of the display unit 13a is changed. Further, the character ROM 67 is a memory for storing data such as symbols 17A to 17H and 17K, background, and characters displayed on the display unit 13a. The image controller 74 adjusts the timing of the CPU 63, the video RAMs 66 to 72, and the input / output port 75, intervenes in reading and writing data, and refers to the character ROM 73 for display data stored in the video RAMs 66 to 72. Thus, it is displayed on the display unit 13a at a predetermined timing.

  Next, characteristic portions of the present embodiment will be described. FIG. 9 is a principle diagram showing a mode of symbols displayed on the plurality of layers LY1 to LY5, LYD, and LYN of the display device 13. As shown in the figure, the symbols displayed on the display unit 13a of the display device 13 are displayed separately on a plurality of (seven in the illustrated example) layers LY1 to LY5, LYD, and LYN. The display is controlled as one screen by overlapping the watermarks. Actually, as shown in the block diagram of FIG. 8, the video RAMs 66 to 72 corresponding to the layers LY1 to LY5, LYD, and LYN hold color images for one screen, respectively. The image display data held in the video RAMs 66 to 72 is stored in the character ROM 73. After the image display data captured by the image controller 74 from the character ROM 73 is once held in the video RAMs 66 to 72, It is converted into a scan data signal and sequentially output. Based on the data output signal, the color, brightness, etc. are controlled and a predetermined pattern is displayed.

  However, in the present embodiment, control is performed so that an image held in the higher priority video RAM is displayed with priority over an image held in the lower video RAM. Specifically, the video RAM 66 corresponding to the fifth background layer LY5 is the lowest, and hereinafter, the video RAM 67 corresponding to the fourth background layer LY4, the video RAM 68 corresponding to the third background layer LY3, the second The video RAM 69 corresponding to the background layer LY2, the video RAM 70 corresponding to the first background layer LY1, the video RAM 71 corresponding to the picture pattern layer LYD, and the video RAM 72 corresponding to the numeric symbol layer LYN are arranged in order of priority. Is set in advance. Further, not only the fluctuation / stop control of the symbols 17A to 17H and 17K, but also the background layer constituted by the first to fifth background layers LY1 to LY5 by a signal from the main board 61 connected to the image controller 74. LY fluctuation control is also performed.

  That is, in the present embodiment, the fifth background layer LY5, which is the lowest priority layer, is controlled to display the sky background symbol including clouds at the top, and the fourth background with the next lowest priority. In the layer LY4, the background symbols of trees and buildings are displayed and controlled in the middle upper part, and in the third background layer LY3 having the next lowest priority, the background symbols of some roads and grasslands are displayed in the center. In the second background layer LY2 with the next lowest priority, a part of the meadow background is controlled to be displayed in the middle and lower parts, and the first background layer LY1 with the second lowest priority is displayed on the first background layer LY1. The background design of the part is controlled to be displayed at the bottom. Then, the background layer LY is totally integrated as a whole. For example, as shown in FIGS. 11A to 11C, the background layer LY is variably displayed as if one background is expressed as a whole. Further, the graphic patterns LY1 to DG8 are displayed on the graphic pattern layer LYD, and the numerical symbols N1 to N8 are displayed on the numeric symbol layer LYN.

  Here, when the symbols 17A to 17H and 17K are not varied, the fifth background layer LY5, that is, only the sky background symbol including the clouds is displayed as if it is varying. As a result, an idyllic landscape as if the clouds are flowing by the wind is displayed.

  In addition, when the symbols 17A to 17H and 17K are changed, the background display objects constituting the first to fifth layers LY1 to LY5, that is, the landscape of trees, buildings, roads, grasslands, etc. as well as clouds. However, variation display control is performed in accordance with variations in the symbols 17A to 17H and 17K (particularly, the symbols DG1 to DG8). At this time, at the time of normal fluctuation of the symbols 17A to 17H and 17K, the background symbol of a part of the foreground grassland that is displayed and controlled in the first background layer LY1 at the bottom is variably displayed at the maximum speed. . In addition, a background pattern of a part of the grassland on the near side next to the display control on the second background layer LY2 in the middle lower part, a road on the near side next to the display control on the third background layer LY3 in the center, and A part of the background design of the grassland, the relatively back side tree and the background design of the building controlled to be displayed on the fourth background layer LY4 in the middle upper part are displayed in a variable manner so that the fluctuation speed becomes slower. The cloud and sky background symbols controlled in the uppermost fifth background layer LY5 are variably displayed at the same speed as when symbols 17A to 17H and 17K are stopped (however, the speed is arbitrary). is there).

  The background symbols controlled to be displayed on the first to fourth background layers LY1 to LY4 are stopped and displayed together with the variations of the symbols 17A to 17H and 17K being stopped. More specifically, the background symbols controlled to be displayed on the third and fourth background layers LY3 and LY4 are stopped and displayed as the symbols 17A to 17H and 17K in the upper symbol row 14 stop changing, and the symbols in the lower symbol row 16 are displayed. The background symbols controlled to be displayed on the first and second background layers LY1 and LY2 are stopped and displayed as the fluctuations of 17A to 17H and 17K are stopped. Furthermore, in the case of “slip stop” for the lower symbol row 16 described above, the background symbols controlled to be displayed on the first and second background layers LY1 and LY2 are also temporarily stored in the same manner as the symbols 17A to 17H and 17K. Fluctuates at high speed and stops suddenly.

  Next, the operation and effect of the present embodiment configured as described above will be described.

  As described above, in the present embodiment, since the background symbol is displayed as if it fluctuates at different speeds depending on the part, all the background symbols are variably displayed only at a constant rate. Unlike the past, it will behave like never before, and the player will be amazed by new surprises and will be more entertaining. In particular, in the present embodiment, a landscape mainly composed of grasslands is displayed. In this case, the background (lowermost) background is controlled to be displayed on the first background layer LY1 corresponding to the grassland on the nearest side. The symbol fluctuates at the fastest speed, and the fluctuating speed of the divided background symbol gradually becomes slower as the distance increases. For this reason, with respect to the background symbols that are variably displayed, a sense of perspective is further imparted and the reality is further increased.

  Further, the background symbol is displayed as if it is a single background as a whole. Therefore, although the background symbols are divided and displayed on the background layers LY1 to LY5, the display can be visually recognized without any sense of incongruity for the viewer.

  In addition, in the present embodiment, the symbols 17A to 17H and 17K for determining the jackpot state are displayed with priority over the background symbols. Therefore, it is possible to pay attention to the behavior that forms the basis of the game, such as fluctuation and stoppage of the symbols 17A to 17H and 17K, without taking too much attention on the background symbols.

  In addition, in the present embodiment, the direction of fluctuation of the background symbols is opposite to the direction of fluctuation of the symbols 17A to 17H and 17K. Accordingly, the grassland displayed based on the background symbols is displayed as if the symbols 17A to 17H and 17K have run through. For this reason, the fun of the variable display is increased as compared with the conventional case. In particular, in the present embodiment, since the dog pictures (characters) DG1 to DG8 are adopted as the factors constituting the symbols 17A to 17H, the background symbols and the pictures DG1 to DG8 are associated with each other. For this reason, it is more meaningful to reverse the direction of fluctuation as described above, and the relevance is further strengthened, and the fun is spurred.

  Furthermore, in the present embodiment, even when the symbols 17A to 17H and 17K are not fluctuating, at least a part of the background symbols (clouds and sky background symbols controlled to be displayed on the uppermost fifth background layer LY5). ) Is displayed in a variable manner. Therefore, even when the symbols 17A to 17H and 17K are not changing, the player can visually recognize and enjoy the behavior of the cloud or the like (the grass or the like does not change).

  In addition, in the present embodiment, when “slip stop” is performed for the lower symbol row 16, the background symbols controlled to be displayed on the first and second background layers LY1 and LY2 are the same as the symbols 17A to 17H and 17K. In addition, the display is suddenly stopped at a high speed. In other words, when the changing speed of the symbols 17A to 17H and 17K is changed, the changing speed of a part of the background symbols is also changed correspondingly. Therefore, the sense of unity between the symbols 17A to 17H and 17K and the background symbol is further strengthened, and further enhancement of interest can be achieved.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows.

  (A) In the above embodiment, background symbols such as grassland are displayed on the display unit 13a. However, any background symbols such as in the sea, in space, in the sky, in the house may be displayed.

  (B) In the above embodiment, the background symbol is divided into five stages in the vertical direction. However, the background pattern may be divided in the horizontal direction, the oblique direction, or in a curved line, or less than four stages, or more than six stages. It may be divided into

  (C) In the above embodiment, as the symbols 17A to 17H, the combinations of the graphics (character) symbols DG1 to DG8 and the numeric symbols N1 to N8 are adopted, but only the symbols may be used or only the symbols and symbols may be used. It is good. Moreover, you may combine symbol factors other than embodiment, such as a combination of another symbol. Furthermore, you may combine 3 or more types of design factors.

  (D) In the above embodiment, the “slip stop” is performed, but the stop may be omitted.

  (E) Although not particularly mentioned in the above embodiment, the ratio of the background symbols to be divided may be changed according to time, a predetermined trigger, and the like. For example, when the symbols 17A to 17H and 17K change, the grassland area may be displayed as if it increases compared to when it does not change.

  (F) As the display device 13, in addition to the liquid crystal display described above, a CRT, a dot matrix, an LED, an electroluminescence (EL), a fluorescent display lamp, or the like may be used.

  (G) It is good also as changing the fluctuation | variation direction of the background symbol divided | segmented according to the site | part (for example, displaying the river which flows to the same direction as the dog symbols DG1-DG8 etc.). Moreover, it is good also as a structure which does not change a part of background design.

  (H) The present invention can also be applied to a pachinko machine of a type different from the above embodiment. For example, it may be implemented as a pachinko machine that is in a special gaming state under the condition that a game ball is awarded in a predetermined area after a jackpot symbol is displayed. In addition to pachinko machines, the present invention can be implemented as various gaming machines such as alepatchi, sparrow balls, and slot machines. In the slot machine, for example, a symbol is changed by operating an operation lever in a state where a symbol effective line is determined by inserting coins, and the symbol is stopped and confirmed by operating a stop button or the like. belongs to. Accordingly, the basic concept of the slot machine is that it is provided with a symbol display means for displaying a fixed symbol after a symbol string consisting of a plurality of symbols is variably displayed, and is caused by the operation of a starting operation means (for example, an operating lever). As a necessary condition, the fluctuation starts and the fluctuation of the symbol is stopped due to the operation of the operation means for stopping (for example, the stop button) or when a predetermined time elapses, and the confirmed symbol at the time of the stop is a specific symbol. The slot machine is provided with special game state generating means for generating a special game state advantageous to the player.

  (I) The present invention may also be applied to a pachinko machine that can execute the probability variation mode or the time reduction mode.

  (J) In the above-described embodiment, the background symbol is displayed as if it is a single background as a whole. On the other hand, it may be displayed as if each divided background symbol represents a completely different background.

  (K) In the above embodiment, the background symbols LY1 to LY5 are individually controlled to be displayed on the background layer, but the background symbols may have overlapping portions. By adopting such a configuration, it becomes possible to blur the boundary portion, to produce a gradation effect, and the like.

  (L) In the above embodiment, the background symbol is scroll-fluctuated, but it may be fluctuated frame-by-frame or may be swung.

  (M) Based on a predetermined opportunity, it is good also as providing a change in a background symbol at least temporarily (for example, displaying as if smoke is emitted from a chimney of a house).

  (N) The change may be adopted as a reach notice or a jackpot notice. By configuring in this way, the player can further visually recognize the background screen, and can further improve the interest.

  (O) In the above-described embodiment, the background symbol variation speed is decreased in the order of the first background layer LY1 to the fourth background layer LY4. However, the background pattern may be partially varied at the same speed. For example, the background symbol controlled to be displayed on the third background layer LY3 and the background symbol controlled to be displayed on the fourth background layer LY4 may be displayed as if they are changing at the same speed.
