By erasing the middle ground screen 4b having a semi-transparent pattern, the entire area of the display surface 3a of the liquid crystal color panel 3 can be used as an animation character screen by the sprite screen 4c and the playability can be improved. in addition,
In this case, along with the reach, the player can be informed of the game situation with three lines. (4) When the semi-transparent symbol is set according to the probability variation information, the display control device 5 displays the probability variation information from the game control device subsequent to turning on the power, starting the game, and winning the game ball, which are not shown in the figure. Take control. That is, the liquid crystal color panel 3
In the state of the game per 3 lines shown in FIG. 4B on the display surface 3a, 7 scroll characters are variably displayed as if they are rotating vertically, and the display control device 5 controls the game control device. In accordance with the probability variation information from 1, the scroll character such as "7" preset as the probability variation pattern is stopped after the reach state with a time difference of about several seconds between each line, and three in any of the three lines. When the uniform big hit state is reached, the semi-transparent pattern of the central upper and lower end portion 7a of the middle ground screen 4b is changed to transparent, or the central upper and lower end portion 7a is set.
By deleting the middle ground screen 4b having a semi-transparent pattern on a, the display surface 3a of the liquid crystal color panel 3 becomes the display screen 6 of the winning game of 3 to 5 lines as shown in FIG. 4A. Therefore, in this case, the number of lines of the symbol combination of the scroll character can be changed from 3 to 5 by using the big hit of the probability fluctuation symbol as a trigger, and the playability can be improved. In addition, in this case, the player can be informed in advance of the game situation with five lines in accordance with the jackpot due to the probability variation symbol.

In short, according to this embodiment, the middle ground screen 4 arranged in front of the scroll screen 4a.
By setting semi-transparent symbols in the two upper and lower portions 7a in the center of b, it is not necessary to manufacture a dedicated image display device 2 for every 5 lines and 3 lines for the symbol combination of scroll characters, The image display apparatus 2 for 5 lines is manufactured by manufacturing the image display apparatus 2 for 5 lines, and incorporating the software corresponding to the specific display means 5e in the control unit 5b of the image display apparatus 2. It is possible to easily change to the image display device 2 and enhance the playability at that time.

Further, according to this embodiment, the reach action can be expressed on the pseudo three-dimensional screen by combining the sprite screen 4c, the middle ground screen 4b and the scroll screen 4a. In other words, as in the above-mentioned conventional example, in the method of constructing a large number of frames in which the screen data extracted from the memory are combined in a plane, and replacing a large number of frames one by one like a picture-story show or day-to-day operation, the animation character It is necessary to replace the scroll characters on the scroll screen when expressing characters or characters. In contrast, in this embodiment, the scroll screen 4a having a large amount of image data and color data is not replaced, but only the color data of the middle ground screen 4b, which requires a small amount of image data and color data, is replaced. It is possible to accurately inform the player of the probability variation between the low probability and the high probability. Therefore, the pseudo three-dimensional screen can be variably displayed while reducing the amount of data for variably displaying.

In this embodiment, the case where a semi-transparent symbol is set in the upper and lower end portions 7a of the center of the middle grand screen 4b at the time of probability change is illustrated and described as an example. However, the present invention uses the semi-transparent symbol as the sprite image 4c. Alternatively, a configuration in which a semi-transparent pattern is set for each part corresponding to each area of the scroll screen 4a in the middle grand screen 4b or the sprite screen 4c is also applicable.

In this embodiment, a pachinko machine is illustrated and described, but the present invention is also applicable to a gaming machine such as a slot machine other than a pachinko machine. When applied to the slot machine, the game start information and the scroll information in the above embodiment are replaced with the information that detects the insertion of medals into the slot machine, and the stop of scroll characters in each of a plurality of lines is stopped on the front of the slot machine. It will be easily understood that the present invention can be applied to a gaming machine such as a slot machine by replacing the operation with a button operation.

[0017]

As described above, according to the present invention, the dimming can be performed by setting the semi-transparent pattern on a part of the screen arranged in front of the scroll screen by the software-specific display means. With a simple structure that does not use a separate member such as a plate, it is possible to change the number of lines of the symbol combination of scroll characters to enhance the game playability, and moreover,
The display screen composed of the animation characters of the sprite screen, the colors or patterns of the middle ground screen, and the scroll characters of the scroll screen is variably displayed on the display surface of the liquid crystal color panel, so that the amount of image data and There is a new effect that a reach action that has never been seen before can be expressed on a pseudo-stereoscopic screen while the amount of data for variable display is reduced as much as possible without replacing the scroll screen with a large amount of color data. Further, by performing the setting of the semi-transparent pattern by scroll information, the entire area of the display surface of the liquid crystal color panel can be used as an animation character screen from the start of the game to the start of the scroll, and the playability can be improved. It has a great effect. In addition, by setting the semi-transparent symbol with probability variation information or reach information, there is a novel effect that the player can be informed of the game situation such as scrolling, probability variation, or reach, and the playability can be improved.
