The font ROM 157 stores the data of each design used for the variable display game and the data of the effect display such as the background and the character.

FIG. 4 shows an example of each of the symbols R1 to R12. These symbols R1 to R12 are identification elements S, such as numerals and alphabets, for identifying whether or not a big hit has occurred.
(1-9, A-C) and decorative elements T depicting a person's face P (other than a person) and hair Q (a wig may be used), and set as three-dimensional patterns R1-R12. is there. The person's face P of the decorative element T is designed to be capable of giving various expressions and being dressed up, and the hair Q is made up of symbols R1 to R1.
Several styles (Q1 to Q3) are set as shown in R3.

In front of the interface 155, a buffer circuit 160 as a signal transmission direction regulating means is provided, and only signal input from the game control device 100 to the display control device 150 is permitted. The γ correction circuit 159 adjusts the display illuminance of the variable display device 4 by correcting the nonlinear characteristic of the illuminance with respect to the signal voltage of the variable display device 4.

Next, an outline of the game will be described with reference to the flowchart of FIG. The variable display area of the variable display game of the variable display device 4 is, for example, a left, right, or middle variable display area.

First, at the beginning of the game (or before the start of the game), the game is in the customer waiting state, and a display command signal for commanding the display of the customer waiting screen is transmitted from the game control device 100 to the display control device 150. On the screen of the fluctuation display device 4, a customer waiting screen (moving image or still image) is displayed.

When the game ball hit in the game area 3 wins the starting port 7, a predetermined random number is extracted by the game control device 100 based on the winning, and the big win of the variable display game is performed. A display command signal for instructing the variable display to be given from the game control device 100 to the display control device 150 is sent to the left of the screen of the variable display device 4,
The variable display of a plurality of symbols is started in the right and middle variable display areas.

After a predetermined time has elapsed after the start of the variable display, the variable display is temporarily stopped in the order of, for example, left, right, and middle (for example, the symbol is slightly fluctuated at the stop position). When a reach state (for example, a combination in which a left symbol and a right symbol may generate a big hit) occurs in the process, a predetermined reach game is performed. In this reach game, for example, the fluctuation display of the symbol in the middle is performed at an extremely low speed, the fluctuation is performed at a high speed, or the fluctuation display is reversed. In addition, background display and character display are performed according to the reach game.

The temporary stop state is a state in which the player can recognize the symbol as a substantially stopped state, and is a state in which the final stop state is not determined. More specifically, in addition to the minute fluctuation at the stop position, there are modes such as displaying a symbol in an enlarged or reduced scale, changing the color of the symbol, or changing the shape of the symbol.

If the result of the jackpot lottery is a jackpot, the symbols in the left, right and middle are finally stopped at a predetermined combination of jackpots, and a jackpot (jackpot game) is generated.

When a big hit game occurs, a special game in which the special variable winning device 5 is opened for a predetermined period is performed. This special game is executed with a predetermined number (for example, 10) of game balls or a predetermined time (for example, 30 seconds) passed into the special variable prize device 5 as one unit (one round). A predetermined round (for example, 16 rounds) is repeated on condition that a prize is won in the continuous winning opening (detection of a winning ball by the continuation sensor 16). In addition, when a jackpot game occurs, the jackpot fanfare display,
A display command signal for instructing the display of the big hit game is transmitted from the game control device 100 to the display control device 150, such as the display of the number of rounds and the display of the big hit, and the big hit game is displayed on the screen of the variable display device 4.

In this case, if the jackpot is a specific jackpot, a specific gaming state is generated after the jackpot game, and the probability of the next jackpot occurrence becomes high probability (probable change), or the game ball is entered into the starting port 7. For example, the change display time of the change display game of the change display device 4 is reduced (time saving).

When a game ball wins in the starting port 7 during the variable display game or the big hit game, the special symbol start memory is stored after the variable display game is completed (at a loss) or after the big hit game is completed. , A new variable display game is repeated. In addition, when the variable display game ends (at the time of loss) or when the big hit game ends, if there is no special symbol start memory, the game is returned to the customer waiting state.

When a game ball passes through the ordinary symbol starting gate 20, a random number related to the ordinary symbol is extracted based on the passing or the ordinary symbol starting memory, and if the random number is a hit, the hit symbol is displayed on the normal symbol display 23. Done,
The normal variable prize winning device 8 of the starting port 7 is expanded for a predetermined time, and winning in the starting port 7 is facilitated.

Next, the symbol display in the variable display game will be described with reference to FIGS.

From the game control device 100 to the display control device 15
When the change display is commanded to 0, the left, right, and middle symbols start to change from the stopped state as shown in FIG. 5, but when the change is started, the right side of the symbol (the right side of the drawing) or Shading is added to the left side of the design (left side of the drawing). Specifically, the decorative element T of the design is shaded.

In this case, when a shadow is added to the right side of the symbol as shown in FIG. 6, the symbol is shifted rightward with the shadow. Also, when a shadow is added to the left side of the symbol, the symbol is shifted leftward with the shadow. The fluctuation is performed by an axis rotation that rotates around an axis passing through the symbol.

Further, the changing speed of the symbol is set according to the shading of the shadow. For example, when a dark shading is given, the symbol fluctuates at a high speed as shown in FIG. 7, and when a light shading is given, for example, the symbol fluctuates slowly.

FIG. 8 shows a stepwise display of the symbol when the symbol is changing to the right. The display during the change (during the rotation of the shaft) is represented by the rotation angle of the symbol.

The next symbol is arranged on the back side of the symbol, and the current symbol disappears in the rotating direction (dark direction with shading) by rotation of a predetermined angle, while the next symbol is turned in the opposite direction (shading). In the light direction without the color).

After a lapse of a predetermined time after the start of the fluctuation,
The fluctuation is temporarily stopped, for example, in the order of left, right, and middle symbols. In this case, depending on the symbol, after the temporary stop, the fluctuation is performed again, and then the temporary stop is performed. In the temporary stop state, the symbol is slightly fluctuated at the stop position, for example.

For example, when the left symbol and the right symbol are temporarily stopped and the left symbol and the right symbol are the same as shown in FIG. 9, a reach state is generated, and a predetermined reach game is performed. Done.

In the reach game, for example, the symbol in the middle is changed at an extremely low speed, fluctuates at a high speed, temporarily stops, or the direction of the change is reversed. Is shaded on the left side, and the design is shifted in the shaded direction. When changing again from the temporary stop, a shadow is added to the right side of the symbol or the left side of the symbol when starting the fluctuation, and when reversing the fluctuation direction, the shaded portion is changed when reversing. . In addition, background display and effect display are performed according to the reach game.

When the left, right and middle symbols are finally stopped changing, the change display game is ended. FIG.
FIG. 11 shows a display example when a losing occurs, and FIG. 11 shows a display example when a big hit occurs.

As described above, the identification element S is added to the variable display game.
Since the variable display is performed using the three-dimensional pattern including the decorative element T and the decorative element T, the variable display with a full three-dimensional effect can be performed.

In this case, since the symbols are shaded and the variable display is performed, the three-dimensional effect is further enhanced. In addition, while displaying the fluctuation by rotating the axis, the symbols appeared from the light direction without shading and disappeared in the dark direction with shading,
The symbols that appear during low-speed fluctuations can be emphasized, making them easier to see.

On the other hand, the display is changed in the shaded direction, that is, the change direction of the symbol is indicated by the shade.
The player comes to pay attention to which of the symbols is shaded.For example, if the temporarily stopped symbol fluctuates again, it is determined whether any of the symbols is shaded and starts to fluctuate in the direction desired by the player. Expectations increase, especially when reach is about to occur or jackpots are about to occur.

Further, while the variable display is performed by shading,
Since the change direction is changed, unexpected change display can be performed. In addition, since the fluctuation speed of the symbol changes according to the shading of the shadow, a fluctuation display rich in changes can be performed.

Therefore, it is possible to perform a variable display rich in effects,
The interest in the variable display game can be sufficiently improved.

Since the decorative element T of the design is shaded, the visibility of the identification element S is not impaired.

There may be a case where the fluctuation is performed without shading the symbol. In this way, a more varied display can be performed.

In addition, when shading is performed, a light shading may be formed before the start of the fluctuation, and this may be gradually increased, and the fluctuation may be started when the predetermined density is reached. By doing so, it is possible to notify when the fluctuation starts (function as a fluctuation mode change notification unit). Further, the shading may be added before the start of the change, and the change may be started after a predetermined time has elapsed, or the shade may be deleted during the change display. In particular, the visibility can be improved when it is not necessary to indicate the change direction (for example, during constant speed change display). Further, the symbol may be erased when the symbol is determined, and the symbol determined state may be notified (the shadow functions as a fluctuating display state notification unit). Further, the shading direction may be switched among a plurality of directions and displayed (for example, alternately left and right), and a sense of expectation may be given in which direction the fluctuation is performed.

On the other hand, the variable display is controlled by the display control device 150. The variable display game is provided with a plurality of progress patterns (variable patterns) of the variable display game and a plurality of shading patterns (shading patterns, etc.) of the identification information. You may choose to get started.

In this case, a reach announcement or a jackpot announcement may be made by shading.

That is, in the case of the reach announcement, the occurrence of the reach is determined based on the selection of the variation pattern so that the reliability of whether or not the reach is caused by the shading and the type of the reach are different. The higher the probability of the display and the special reach, the higher the probability, for example, the higher the shading, and the fluctuating display is performed.

In the case of the jackpot announcement, when the occurrence of the jackpot is determined, for example, the shadow is darkened with a high probability so that the reliability of whether or not the jackpot occurs due to the shadow is made different.

In these cases, in addition to the shading of the shadow, for example, the timing of shading may be advanced or delayed.

In this way, it is possible to obtain a higher interest in the variable display.

In this case, the game control device 100 is provided with a plurality of progress patterns (variation patterns) of the variation display game and a plurality of shading patterns (shading patterns, etc.) of the identification information, and when the start condition is satisfied (for example, the start port 7). At the time of winning) or when the fluctuation start condition is satisfied (for example, when the previous fluctuation display game ends or the big hit game ends).
Alternatively, the game control device 100 may select each pattern based on the game state, and instruct the display control device 150 about this. In this way, it is possible to select each of the patterns based on the game state and control a detailed effect. Further, the display control device 150 includes a plurality of progress patterns (variation patterns) of the variable display game and a plurality of shading patterns (shading patterns, etc.) of the identification information, and the display control device 150 selects each pattern. May be. By doing so, it is possible to reduce the load on the game control device 100 and perform various effects.

Further, in the embodiment, the example in which the symbol is shaded has been described. However, the color tone of the symbol may be partially changed. That is, the color tone may be partially increased, decreased, or made darker, lighter, or the timing of changing these may be made earlier or later. Get.

Although the symbols appear from the light direction and disappear in the dark direction, the setting of the light and dark portions by shading or color may be set in a relative relationship. That is, a light portion and a dark portion may be set, a dark portion may be represented by setting a light portion (for example, a predetermined portion is made brighter), or a dark portion may be set (for example, a predetermined portion is made darker).
The bright part may be represented by. Further, the setting of the bright part and the dark part may be performed in association with the background and the effect of the character. For example, as shown in FIG. 6, the setting of a bright portion and a dark portion may be performed by a spotlight K in the background.

Although the fluctuation of the symbol has been described in the case of rotating the axis, the present invention can be applied to a case where the screen of the fluctuation display device 4 is scrolled from the upper side to the lower side or from the lower side to the upper side. For example, when scrolling from above to below, the upper part of the symbol may be set as a bright part and the lower part may be set as a dark part.

The direction in which the symbol fluctuates has been described in the case where the shaft rotates. For example, the fluctuation direction is not limited to two directions of up and down and left and right, but four directions of up, down, left and right, or eight directions obtained by adding an oblique direction to the direction. Or a surprising and irregular change direction. When there are a plurality of change directions, the player does not know the change direction uniquely, but suggests the direction, so that the player can be prevented from being confused.
Further, in the plurality of fluctuation directions, a fluctuation direction or the like that leads to a result that is advantageous to the player is set (for example, a direction in which reach is likely to appear: this setting means is referred to as a result mode derivability setting means). The suggestion of the direction may be linked to an interest improvement.

As a reach notice (fixed notice), for example, during the variable display game, the left, right, and middle symbols are [1 (R
1), 2 (R2), 3 (R3)], [4 (R4), 5 (R
5), 6 (R6)], when the vehicle is temporarily stopped in a line, the left symbol or the right symbol is changed again, and the left symbol and the right symbol are temporarily stopped at the same symbol. A reach state may be generated.

For example, when the symbols on the left, right, and inside are temporarily stopped, as a notice with a high expectation of the jackpot or the expectation of the jackpot of the probability change, [A (R10), B (R1
1), C (R12)] etc. or [7
(R7)] may appear at a predetermined appearance rate.

In the embodiment, an example in which the present invention is applied to a pachinko gaming machine as a gaming machine has been described.
For example, the present invention can be applied to gaming machines such as pachislot and arrangement balls.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
