2. Description of the Related Art Conventionally, a pachinko machine is known as a game machine of this type. A conventional pachinko machine displays a plurality of special symbols in a variable manner on a symbol display device when a hit ball wins a starting winning opening. Then, when a combination of special symbols stopped and displayed on the symbol display device constitutes a predetermined prize mode, an advantageous special game is performed as compared with the normal game.

The special symbols displayed on the symbol display device are divided into, for example, three groups arranged side by side, and a plurality of numbers are variably displayed for each symbol group. And the left symbol group (first
Stop symbols), right symbol group (second halt symbol), middle symbol group (third halt symbol), the variable display of numbers is stopped in order, and the combination of numbers that are halted in each group is "7""7"."7"
Special games can be played when the same combination is obtained, such as.

In such a pachinko machine, in addition to the variable display of the special symbol, the effect by the lamp and the voice is elaborately designed, and thereby, the interest of the game is increased. For example, as an effect that satisfies the player's sense of superiority, before the variable display of the special symbols in all the symbol groups is stopped, the stop display mode of the special symbols is a jackpot that allows the transition to the special game. A presentation is made to give advance notice of whether or not.

In such a notice production, a special sound is generated during the change of the special symbol, or a notice lamp provided on the front frame is turned on or blinked to notify that a big hit will occur. .

As such a notice effect, for example, in Japanese Patent No. 2772787, the notice indicator provided on the front frame is turned on or blinked, or the speed or brightness of the variable display of the special symbol is changed, Techniques for making a big jackpot announcement are disclosed.

[0007]

However, various sounds such as guide broadcasting, sound for picking up a game ball, effect sound in other gaming machines, etc. are overflowing in the game store, and even if a notice effect sound is generated. , There was a risk of missing the notice effect sound.

Further, since a large number of effect lamps are provided on the front frame in addition to the notice lamp, the notice lamp has a low degree of attention, and there is a possibility that the notice effect may be overlooked.
In this way, if the player cannot detect the notice effect, the purpose of the notice effect that makes the game more interesting cannot be achieved.

Further, in the notice effect for changing the speed of the variable display of the special symbol, the notice effect is changed by changing the changing speed for each special symbol so that the predetermined special symbol is stopped and displayed after the lapse of a predetermined time. However, it is difficult to perform such control in a gaming machine that uses a rotating reel as a symbol display device.

Further, in the notice production in which the brightness of the special symbol is changed, it is necessary to make the brightness different between the normal production and the notice production so that the difference in brightness can be recognized. Here, when the brightness of the special symbol during the normal effect is darkened, it is necessary to change the symbol in a dark state for a long time, the effect of the effect cannot be enhanced, and the eyes of the player are tired. I will end up. on the other hand,
If the brightness of the special symbol is reduced during the notice production, it is not possible to raise the player's expectation for the occurrence of the big hit.

As another method of the notice effect, there is known a method of displaying a special character or the like in addition to the special symbol to be displayed in a variable manner on the liquid crystal display device. According to this method, since the advance notice display is performed by using the liquid crystal display device which is highly noticed by the player, the player can be surely notified, but the gaming machine using the rotating reel as the symbol display device. Cannot be applied to.

The present invention has been proposed in view of the above-mentioned circumstances, and can be applied even to a gaming machine having a different structure of symbol display means, and it is possible to reliably and effectively shift to a special game. It is an object to provide a game machine that can give a notice and a computer program for realizing the function of the game machine.

[0013]

A gaming machine and a computer program according to the present invention have the following characteristic points in order to achieve the above-mentioned object.

That is, the gaming machine according to the present invention variably displays a plurality of special symbols for each of a plurality of symbol groups when a predetermined start condition is satisfied, and after a lapse of a predetermined time, the special symbols for each of the plurality of symbol groups. A symbol display means for sequentially stopping display, and a stop symbol determination means for determining a stop display aspect of the special symbol in the plurality of symbol groups are provided, and a stop display aspect of the special symbol in the plurality of symbol groups is predetermined. When a prize mode is configured, in the gaming machine that allows the player to perform a special game that is more advantageous than the normal game, if the stop symbol determination unit determines that the prize mode is set, all Before the variable display of the special symbols in the symbol group is stopped, the stop display mode of the special symbols in the symbol group in which the variable display of the special symbols has already stopped is determined to be the prize mode. It is characterized in that notice that it was.

In this case, the advance notice can be made by the stop display mode of the special symbols in the other symbol groups except the symbol group in which the variable display of the special symbols is stopped at the end.

Further, the advance notice can be made in a stop display mode of the special symbol in the symbol group in which the variable display of the special symbol first stops.

Further, the symbol display means can be constituted by a plurality of rotating reels on the surface of which the plurality of special symbols are displayed.

A computer program according to the present invention is
Using a computer, when a predetermined start condition is satisfied, a plurality of special symbols are variably displayed for each of a plurality of symbol groups, and a symbol display for sequentially displaying the special symbols for each of the plurality of symbol groups after a lapse of a predetermined time. Means and stop symbol determining means for determining the stop display mode of the special symbol in the symbol display means, when the stop display mode of the special symbol in the plurality of symbol groups constitutes a predetermined prize mode, In the computer program for realizing the function of the gaming machine that allows the player to perform a special game that is more advantageous than the normal game, in the case where the stop symbol determination means determines that the prize mode is achieved, all Before the variable display of the special symbols in the symbol group is stopped, the variable display of the special symbols is already stopped by the stop display mode of the special symbols in the symbol group, It is characterized in that an additional function of warning that that the embodiment has been determined.

Explaining each of the means concretely, the symbol display means is composed of, for example, a plurality of rotating reels,
The stop symbol determination means is constituted by, for example, a control device.

It should be noted that the above-mentioned notice is not a vague notification of the possibility of transition to a special game with a certain probability, such as so-called reach production, reach-eye production, etc., but the notice is given. If it is revealed, it is always possible to shift to a special game. For example, when there are three symbol groups, as a first stop symbol and a second stop symbol, by stopping and displaying a special symbol of a special combination, it is possible to give a notice to shift to a special game.
