Next, according to the block diagram shown in FIG.
A schematic configuration of a portion for performing game control in the electric control device 130 will be described. Electric control device 13 for performing game control
As shown in FIG. 1, a credit medal insertion switch 100, a start switch 80, stop switches 90 to 92, and a settlement switch 110 are connected to the 0 input side. Then, as shown in FIG. 1, rotating reels 40 to 42 are connected to the output side of the electric control device 130.

As shown in FIG. 1, the electric control device 130 includes a random number generating means 131 for generating a random number for determining a combination of symbols to be stopped and displayed on the display windows 31 to 33, and a random number generating means 131. A random number extracting unit 132 that extracts a random number from the generated random numbers and determines a symbol to be stopped and displayed on the display windows 31 to 33, and a combination of the symbol stopped and displayed on the display windows 31 to 33 is a predetermined prize. A symbol determining means 133 for determining whether or not the mode, and when the symbol determining means 133 is determined to be a combination of specific symbols for performing a special game, while determining the type of the specific symbol,
Based on the determination result, the specific symbol determining means 134 for determining the number of consecutive occurrences of the specific symbol, and until the number of continuations determined by the specific symbol determining means 134, the occurrence probability of the specific symbol to a higher than normal probability The change probability changing means 135 is a main component.

A control of a game performed by the electric control device 130 when a specific symbol for performing a special game is generated will be described with reference to a flowchart of FIG. First, when the player operates the start switch 80 after inserting a medal from the medal insertion slot 60 or after inserting a credit medal, the rotating reels 40 to 42 rotate, and the front panel 20 is rotated.
In the display windows 31 to 33 provided in the, a plurality of symbols shown on the rotating reels 40 to 42 are sequentially moved and displayed at high speed. At this time, the random number extracting means 132 extracts a random number from the random numbers generated by the random number generating means 131 and determines a combination of symbols to be stopped and displayed on the display windows 31 to 33.

[0016] Then, the player operates the stop switches 90-92.
, The reels 40 to 42 stop, and the display windows 31 to
The symbol displayed at high speed in 33 stops based on the combination determined by the random number extracting means 132. Here, the symbol determination means 133 determines the combination of the symbols stopped and displayed. If the combination of symbols stopped and displayed is a combination of symbols that are predetermined, a predetermined number of medals are paid out as a prize.

The symbol determining means 133, when determining that the combination of the stopped symbols is a specific symbol for performing a predetermined special game, determines the type of the specific symbol by the specific symbol determining means 134. Is determined. In the present embodiment, the specific symbol is a combination of “7”, “7”, and “7”, and in the combination of “7”, “7”, and “7”, all “7” are displayed in blue. There are three types of combinations, one in which all “7” are represented in red, and one in which all “7” are represented in gold.

The specific symbol determining means 134 determines whether the combination of "7", "7" and "7" is a combination of blue "7", a combination of red "7", or a combination of gold. Is determined, and the number of continuous occurrences of the specific symbol is determined based on the determination result. In the present embodiment, when the blue color is “7”, “7”, or “7”, the number of continuous occurrences of the specific symbol is one, that is, the special bonus game is only one, and the red symbol is red. "7""7"
In the case of "7", the special bonus game, the large bonus game, is continued twice, and in the case of the golden "7,""7," or "7," the special bonus game of the large bonus game is reduced to three. Times.

In the case of red “7”, “7” and “7”, and in the case of gold “7”, “7” and “7”, a specific symbol is generated by the probability changing means 135. The probability of performing is higher than the probability in the normal game. In this embodiment, for example, when the occurrence probability of a specific symbol in a normal game is 1/200, the probability changing unit 135 increases the occurrence probability of the specific symbol by a factor of 1/20, which is 10 times higher than that of the normal game. And Therefore, after the large bonus game, which is a special game, is completed, the probability that the next large bonus game will occur increases, and the large bonus game can be continuously performed.

When the number of continuous occurrences of the specific symbol determined by the specific symbol determining means 134 ends, the probability changing means 135 returns the probability of occurrence of the specific symbol having a higher probability than that of the normal game to the probability of occurrence during the normal game. . In the present embodiment, when the red bonus is “7”, “7”, “7”, the two large bonus games are completed, and when the golden bonus is “7”, “7”, “7”, After the end of the three large bonus games, the occurrence probability of the specific symbol, which was 1/20, is changed to 1/200.

Specifically, for example, when the combination of the symbols stopped and displayed is “7”, “7”, “7” in red, the probability of occurrence of the specific symbol is reduced by the probability changing means 135 to 1 /. It is changed from 200 to 1/20. Then, the game can be played with the occurrence probability of the specific symbol being 1/20. In the state where the probability of occurrence of the specific symbol is high, the specific symbol determination means 134 does not determine the specific symbol and determine the number of continuous occurrences of the specific symbol. That is, after the occurrence probability of the specific symbol is changed from 1/200 to 1/20 by the probability changing unit 135,
The symbol determination means 133 only determines whether the combination of symbols stopped and displayed is a combination of specific symbols. Then, when the number of continuous occurrences of the specific symbol determined by the specific symbol determination means 134 ends and the occurrence probability of the specific symbol is changed, the combination of “7”, “7”, and “7” is again changed to “7” of any color. Is determined, and the number of continuous occurrences of the specific symbol is determined based on the determination result.

Thereafter, the above-described processing procedure is repeated.

[0023]

Since the present invention is configured as described above, it has the following effects. Claim 1
According to the invention described in the above, when the symbol is determined to be a specific symbol for performing a predetermined special game in the determination of the symbol determining unit, the specific symbol determining unit determines the type of the specific symbol and determines. The number of continuous occurrences of the specific symbol is determined based on the type of the specific symbol. Then, the probability changing means changes the occurrence probability of the specific symbol to a higher probability than usual until the number of times of continuation determined by the specific symbol determining means is reached, so that the specific symbol easily occurs.

Therefore, once a specific symbol for performing a special game is generated, the specific symbol is likely to be continuously generated, so that the player does not lose a large amount of medals obtained in the special game, and furthermore, the special game can be performed. More likely to do
The interest of the game can be significantly increased.
