Thereafter, the game control unit 11 repeats the remaining time process of updating the display symbol determination random number and the determination random number until a timer interrupt signal is given (S111).

FIG. 4 is a flowchart showing a processing example in the special symbol process processing of FIG. In the special symbol process processing, the corresponding processing is selectively executed according to special figure flag information for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. Then, the value of the special figure flag information is updated during each processing according to the gaming state. In the special symbol process process, the following processes are executed corresponding to the special figure flag information.

When the value of the special figure flag information is "0", it is determined whether or not the random number value drawn in the special figure game is equal to the jackpot value, or a normal game such as a process of notifying the outside to the outside. The "special symbol normal process" in the state is executed (S201). When the value of the special figure flag information is “1”, it is determined whether or not the symbol stopped on the special symbol display device 4 has become a big hit mode.
Is executed (S202).

When the value of the special symbol flag information is "2", a "special symbol stop symbol setting process" for setting a stop symbol in the special symbol game performed on the special symbol display device 4 is executed (S203). When the value of the special figure flag information is “3”, a “variable display pattern setting process” for setting a variable display pattern of a symbol of a special figure game performed on the special symbol display device 4.
Is executed (S204).

When the value of the special figure flag information is "4", "special design change processing" for performing the change processing in the special figure game is executed on the special symbol display device 4 (S205). When the value of the special figure flag information is “5”, “special symbol stop processing” for performing a special symbol deceleration stop processing is executed (S20).
6).

When the value of the special figure flag information is "6", a "large winning opening pre-opening process" for performing an initialization process for the big hit operation is executed (S207). When the value of the special figure flag information is “7”, various processes relating to the jackpot operation and “the process of opening the special winning opening 7” for checking the opening time of the special winning opening 7 per time are executed (S208).

When the value of the special figure flag information is "8", the "specific area effective time process" for monitoring the passing of the game ball to the specific area switch and determining whether or not the special symbol process is completed is executed. (S209). When the value of the special figure flag information is “9”, it is determined whether or not the special symbol process has been completed. If the special symbol process has been completed, the demonstration display (big hit screen) flag is cleared, the big hit display pattern is cleared, and the big hit end display is performed. A "big hit end process" for clearing and clearing the big hit information is executed (S210).

The processes executed in the special symbol process are not limited to the above-described processes, but may be replaced with other processes or further other processes may be added. Also, if the processing contents of each processing branched according to the value of the special figure flag information become complicated and the processing cannot be completed within the timer interrupt time,
A plurality of the same processes may be added.

In the special figure game, when a game ball passes through the special symbol starting port 6, a special symbol big hit or a loss is determined based on the value of the random number for determination. As a result of the determination, when a jackpot is won, the special symbol combination corresponding to the value of the random number for determination is displayed on the special symbol display device 4. On the other hand, when a loss occurs, a special symbol corresponding to the value of the display symbol random number is displayed.

FIG. 5 is a diagram showing a shape model of a virtual drum defined as a three-dimensional object in a virtual three-dimensional space in this embodiment. Virtual drum 31 (31L, 31C, 31
R) is a shape model of a polygonal column having a substantially cylindrical shape, and its surface is formed by a plurality of plate polygons 32. When approximating a cylindrical shape by a polygon, the more the number of corners, the more a smooth cylindrical shape can be represented. However, even if the number of corners is increased without limitation, the accuracy cannot be improved in spite of the increase in the number of plate polygons 32 and the amount of data, so that the virtual drum 31 in this embodiment is set to a 48-gon.

Also, at the time of the normal fluctuation display in this embodiment,
Virtual drum 3 in the order of virtual drums 31L, 31R, 31C
Display control is performed so that one rotation stops. For this reason,
The first stop symbol is a display symbol when the rotation of the virtual drum 31L stops, and similarly, the second stop symbol is a display symbol when the virtual drum 31R stops, and a third stop symbol (hereinafter, a final stop symbol). The symbol is a display symbol when the virtual drum 31C stops.

FIG. 6 is a diagram showing a texture image mapped on the surface of the virtual drum. Texture image 3
3L and 33C are one of “1” to “9” and “A” to “C”.
Bitmap format image data representing a display pattern as two pieces of identification information, and the texture image 33R is bitmap format image data representing a display pattern reversely arranged to the texture images 33L and 33C. . This is when the first stop symbol and the second stop symbol temporarily stop,
This is for producing a reach display mode such as a so-called double reach or triple reach by using a plurality of effective lines for a big hit.

Since the virtual drum 31 in this embodiment has a 48-gon shape, one display symbol is mapped for every four continuous plate polygons 32. Further, if a texture image is simply mapped to each plate polygon 32, a shadow is generated at a boundary portion of each plate polygon 32 when a virtual light source is provided, and a columnar shape is lost. For this reason, glow shading is applied to each virtual drum 31 so as to represent a smooth curved surface.

Hereinafter, the display processing in this embodiment will be described. The following images are displayed in the display area of the special symbol display device 4.

FIG. 7 is a diagram showing an example of the effect display at the time of the reach effect display in this example. First, special design opening 6
When the game ball wins, various random numbers are obtained as described above, and the reach variation pattern is determined. Here, when it is determined that the reach effect display is to be performed based on the random number value, after the virtual drum 31 is started to fluctuate, the virtual drum 31 is temporarily stopped in the order of 31L and 31R, and FIG. As shown in a), the first stop symbol and the second stop symbol match in the same display symbol ("8" in this example), that is, a so-called reach state is established, and thereafter, the reach effect display is executed.

In the reach state, as shown in FIG. 7 (b), the display changes to an angle in which the virtual drum 31 is viewed obliquely from the front, and then, as shown in FIG. 7 (c), the virtual drum 31L , 31R are separated from each other. Then, by changing the modeling information of the virtual drums 31L and 31R in this state, as shown in FIG.
The shapes of the virtual drums 31L and 31R change from a cylindrical shape to a hexagonal prism shape.

As shown in FIG. 7E, the virtual drum 31
When the shapes of L and 31R completely change to hexagonal prism shapes, next, as shown in FIG.
R returns to the center, respectively, and becomes integral with the virtual drum 31C. At this point, the virtual drum 31 has a hexagonal prism shape.
The six sides of L, 31R include “1” to “9”, “A”
To "C" are arranged two each. For this reason, when the first stop symbol and the second stop symbol are temporarily stopped after the virtual drums 31L and 31R are deformed into a hexagonal column shape, a so-called double reach state in which two effective lines are provided.

Then, as shown in FIG. 7 (g), the virtual drum 31C displaying the final stop symbol is temporarily stopped, and the final stop symbol is displayed as the first stop symbol and the second stop symbol. If they match one or the other,
As shown in FIG. 7 (h), the angle is returned to its original state, the fact that a big hit has been notified, and the opening operation of the special winning opening 7 is performed. In this way, by adopting a video expression having a high visual effect in the reach effect display in which a sense of expectation that is a big hit is increased, it is possible to improve a game entertainment.

(Modification Example 1 of First Embodiment) In the above-described effect display example, the case where the reach effect display that develops to double reach on the special symbol display device 4 is performed has been described. It is also possible to perform a reach effect display that develops into a triple reach by adopting a quadrangular prism shape.

FIG. 8 is a diagram showing an example of an effect display at the time of the reach effect display in this example. First, special design opening 6
When the game ball wins, various random numbers are obtained as described above, and the reach variation pattern is determined. Here, if it is determined that the reach effect display is to be performed based on the random number value, after the virtual drum 31 starts to fluctuate, the virtual drum 31 temporarily stops in the order of 31L and 31R. As shown in a), the first stop symbol and the second stop symbol match in the same display symbol ("8" in this example), that is, a so-called reach state, and thereafter, a reach effect display is executed.

In the reach state, as shown in FIG. 8 (b), the display changes to an angle in which the virtual drum 31 is viewed obliquely from the front, and then, as shown in FIG. 8 (c), the virtual drum 31L , 31R are separated from each other. Then, by changing the modeling information of the virtual drums 31L and 31R in this state, as shown in FIG.
The shapes of the virtual drums 31L and 31R change from a cylindrical shape to a rectangular prism shape.

As shown in FIG. 8E, the virtual drum 31
When the shapes of the L and 31R completely change to a quadrangular prism shape, next, as shown in FIG.
R returns to the center, respectively, and becomes integral with the virtual drum 31C. At this point, the virtual drum 31 has a rectangular prism shape.
The six sides of L, 31R include “1” to “9”, “A”
To "C" are arranged three by three. Therefore, when the first stop symbol and the second stop symbol are temporarily stopped after the virtual drums 31L and 31R are deformed into the shape of a quadrangular prism, a so-called triple reach state in which three effective lines are provided is provided.

Then, as shown in FIG. 8 (g), the virtual drum 31C for displaying the final stop symbol is temporarily stopped, and the final stop symbol is displayed as a first stop symbol and a second stop symbol. If they match one or the other,
As shown in FIG. 8 (h), the angle is returned to the original position, the fact that a big hit has been notified, and the opening operation of the special winning opening 7 is performed. In this way, by adopting a video expression having a high visual effect in the reach effect display in which a sense of expectation that is a big hit is increased, it is possible to improve a game entertainment.

Although the gaming machine of the present invention has been specifically described based on the embodiment, the present invention is not limited to the above-described embodiment, and various modifications and alterations may be made without departing from the gist of the invention.
