Abstract

PURPOSE:To further enhance the fun of a game by constituting the slot machine so that a lottery means is operated at the time when combination of patterns becomes a specific combination for a bonus game. CONSTITUTION:In the slot machine, two kinds of games are provided as bonus games, and when a condition for migrating to a lottery game is formed, a controller 7 actuates automatically a lottery means 8 and when an actuating signal is applied to a binary counter & decoder circuit 8b from the control means 7, display lamps B, S and O are flickered in order by a period determined by a clock signal. In such a state, when lottery is executed by depressing a start lever 2, while looking at flickering of three pieces of display lamps B, S and O, the controller 7 applies a stop signal to a randam delaying circuit 8a of the lottery means 8, and when an output is inputted to the binary counter & decoder circuit 8b and stops the count, flickering of the display lamps B, S and 0 stops, they become a state that only one lamp of three pieces is turned on and a result of lottery is fed back to the control means 7. As a result, by executing one of the bonus games, the game can be allowed to have a variation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention rotates a plurality of rotating bodies each having a plurality of types of designs drawn on the periphery, and then sequentially stops the rotating bodies so that the rotating bodies are positioned at a predetermined winning line. The present invention relates to a slot machine in which winnings and a plurality of types of games as a bonus game are determined when the combination of symbols of each rotating body becomes a predetermined combination.

[Conventional technology]

In a conventional slot machine, if the combination of the symbols of each rotating body positioned on a predetermined winning line when each rotating body stops becomes a specific combination determined for each, after paying out a predetermined number of winning medals, It was configured to automatically move to one of a plurality of types of games as a bonus game. Incidentally, as a plurality of types of games as a bonus game, a continuous accessory game and a continuous accessory increase game are generally known, and the following explanation will be continued by taking as an example the case where these games are used as a bonus game.

Two types of specific silk combinations are defined as conditions for transitioning to the continuous pitching game, and if either combination is achieved, the game is executed. In this game, after rotating multiple rotating bodies in the same manner as in general games, when one of the multiple rotating bodies is stopped, the symbol stops at a predetermined position or a specific symbol. Win a prize and receive a predetermined number of medals or a refund. This is done for all rotating bodies. After one set of rotating all rotating bodies and then stopping all rotating bodies is repeated a predetermined number of times, the continuous pitching game ends and the game returns to the general game.

The continuous accessory increase game is executed when a specific combination different from the continuous pitching game is obtained. In this game, the continuous pitching game is repeated a plurality of times, or a general game is played before each round, and depending on the result, the continuous pitching game is executed or not.

[Invention or problem to be solved]

Conventionally, when playing a general game, if the combination of symbols on a plurality of rotating bodies becomes the combination determined for each of the multiple types of games as bonus games, the multiple types of games as bonus games are simply Since the game involves executing one of the following, the game becomes monotonous, and improvements in the - layer have been desired.

The present invention aims to improve the above-mentioned conventional slot machine and further enhance the fun of the game.

[Means to solve the problem]

The slot machine according to the present invention rotates a plurality of rotating bodies each having a plurality of types of symbols drawn on their peripheries and then stops them one after another, so that the combination of the symbols of each rotating body located on a predetermined winning line becomes a predetermined combination. The first feature is that a lottery is performed to determine which of the plurality of games to be played as the bonus game. A lottery means for determining the bonus game is provided, and the lottery means is configured to operate when the combination of symbols becomes a specific combination for the bonus game.

A second characteristic configuration is that the lottery means is configured so that a lottery can be drawn even if the lottery means does not execute any of the plurality of games as the bonus game.

[For production]

According to the first characteristic configuration, when the combination of symbols becomes a specific combination for the bonus game, the lottery means operates to determine which of the plurality of games as the bonus game should be played. Execute the lottery of keys. Depending on the result, the game moves to one of a plurality of types of bonus games.

Further, according to the second characteristic configuration, the lottery result by the lottery means may be a loss J, and in this case, the game returns to the general game without executing any bonus game.

〔Effect of the invention〕

According to the present invention, the bonus game is played based on the lottery result by the lottery means, compared to the conventional game in which the game simply moves to one of a plurality of types of games as a bonus game depending on the combination of the symbols in the general game. The game can be varied by running one of several types of games, so −
Now we have a slot machine that can be enjoyed by many people.

Further, according to the second characteristic configuration, by letting the lottery means also draw "losers", the probability of transitioning to the lottery is increased without increasing the probability of transitioning to the bonus game compared to the conventional one, and the probability of transitioning to the bonus game is increased. It is possible to moderately increase the sense of anticipation of the game, and thus make it possible to enjoy the game with even more interest.

〔Example〕

Embodiments of the slot machine of the present invention will be described below based on the drawings.

FIG. 1 is an external view of the slot machine of this embodiment as seen from the front, and FIG. 2 is a block diagram showing the flow of main control signals inside the machine.

This slot 1 machine has a medal slot (1), a start lever (2), and three reels (3) as multiple rotating bodies.
), three stepping motors (M) that drive and rotate these reels (3) individually, and three stop buttons (4) that individually stop the rotation of each reel (3). (3) has a plurality of types of symbols displayed along its outer circumferential surface. In each of the three display windows (5), three symbols out of the symbols drawn on the outer peripheral surface of each reel are displayed in a vertical line. Therefore, a total of nine symbols are displayed in the three display windows (5).

An outline of the operating procedure and its control is as follows. First, after inserting 1 to 3 medals from the medal slot (1), press the start lever (2). Then, a game start signal or control means equipped with a microcomputer (7)
is input.

The control means (7) determines the number of medals inserted based on the signal from the medal insertion detection means (la), and then drives the motor (M) to rotate the reel (3).

When the three reels (3) reach a predetermined rotational speed, the stop button (4) can be pressed.

The user presses the three stop buttons (4) in any order to stop the three reels (3) in sequence. At this time, the control device (7) controls the corresponding reel (
3) is controlled to stop.

Then, when the rotation of the three reels (3) stops, the three reels (3)
A winning is determined when the combination of symbols displayed in each display window (5) becomes a predetermined combination along a winning line set horizontally or diagonally. At this time, the control device (7
) drives the medal discharging means (6a) to dispense a predetermined number of medals onto the receiving tray (6), and the I-game ends. If the above winning conditions are not met, one game ends without medals being paid out.

The rotational position of each reel (3) is detected by the respective reel position detection means (3a), and a detection signal is sent to the control means (7).
), the control means (7) can determine the symbol to be displayed on the display window (5) based on this detection signal. Also, reel the symbol (3)
It is also possible to control the probability of winning by predicting before the reels stop and applying an appropriate delay to the reel stops.

The winning line is determined by the number of medals inserted at the start of the game. If there are - medals, there will be only one horizontal line in the center, if there are two medals, there will be two horizontal lines above and below, and if there are three medals, there will be three winning lines. In addition, there are 5 different settings, including 2 diagonal lines.

Moreover, more than ten types of symbol combinations are determined as the above-mentioned winning conditions, and the number of medals to be paid out is changed depending on the probability that each combination will be realized. Specifically, 2
The range is from 1 to 15, and the number of cards is determined in stages such that the lower the probability of a combination, the larger the number of cards.

The above is a general game, but when the combination of symbols along the entered prize line becomes a specific combination with the lowest probability, after 15 medals are paid out, the game does not end and the following is continued: Shift to the lottery game for the bonus game.

The slot machine of this embodiment has two bonus games.
There are different types of games.

One is a continuous bonus game with medium winnings, and the other is a continuous bonus game with jackpots. The specific contents of these will be described later.

Therefore, a lottery game is held in which one of the three types of bonus games is selected, including the possibility of executing either of the two types of bonus games or not executing any of the bonus games. That is, when the conditions for shifting to the aforementioned lottery game are satisfied, the control device (7) automatically activates the lottery means (8).

The lottery means (8), as shown in FIG. ),
It consists of a random delay circuit (8a).

From the control means (7) to the binary counter & decoder circuit (8b
), the display lamps (B), (S), and (0) blink in sequence at a period determined by the clock signal. 3 indicator lamps (B), (S), (0)
As shown in FIG. 1, is arranged above the three display windows (5) mentioned above. Customers using this slot machine will see these three indicator lamps (B) and (S).

While watching (0) flash, press the start lever (2) to draw a lottery. In other words, the start lever (2) operated in the general game is also used as a lottery lever in this lottery game.

When detecting that the start lever (2) has been pressed, the control device (7) gives a stop signal to the random delay circuit (8a) of the lottery means (8). The random delay circuit (8a) provides an appropriate random delay time to the stop signal, and may be included in the control means (7). Random delay circuit (8
The output of a) is the binary counter & decoder circuit (8b).
is input and the count is stopped. Then the indicator lamps (B) and (S) will appear.

(0) stops blinking, and only one of the three lamps remains lit. Thereby, the customer knows the lottery result, and the lottery result is fed back to the control means (7).

As a result of the lottery, if the indicator lamp (B) lights up, the game shifts to a continuous throw increase game, and if the indicator lamp (S) lights up, the game shifts to a continuous accessory game. If the display lamp (0) lights up, it means that you have lost, and after the 15 medals as a consolation prize are paid out, the display lamp (0) goes out and the game returns to the regular game.

A flowchart of the lottery game for the above general game and bonus game is shown in FIG.

Next, the continuous yakuza game and the continuous pitch increase game will be briefly explained. When entering the continuous yakuza game, the customer inserts one medal and then presses the start lever (2). Then, three reels (3) rotate. Next, pressing any stop button (4) will stop the corresponding reel. (
The other two reels continue to spin. ) At this time, if the symbol located in the center of the display window (5) of the stopped reel (3) is a specific symbol, it will be a win and 15 medals will be paid out. Next, the stop button (4) is pressed in the same manner for the other two rotating reels to play the game. One game ends when all three reels (3) stop, but after inserting medals again, Star 1 to Lever (2)
) The above game can be repeated a total of 4 times.

The continuous pitch increase game is a game in which the general game and the consecutive yakuza game described in "2" are alternately repeated three times. When entering the continuous throw increase game, first a general game is played, and as a result, if the combination of symbols displayed in the three display windows (5) becomes a specific combination along the winning line, the above-mentioned continuous Run the role game once. If you perform the combination of this general game and the continuous yakumono game three times in total, you will get a continuous throw increase game (5).
ends and returns to the general game.

[Another example]

In the embodiments described above, two types of games are provided as bonus games, but three or more games may be provided.

The lottery means (8) in the above embodiment generates the three lottery results with the same probability, but the binary counter & decoder circuit (8b) is changed or synchronized with the random delay circuit. The configuration may be such that the probability of occurrence can be changed.

Further, the lottery means (7) may be a fourth reel (3') as shown in FIG. That is, on the outer circumferential surface of the fourth reel (3'), three types of symbols corresponding to the three lottery results are drawn in proportions according to the probability that each of them should occur, and one of them is drawn. Only the design should be displayed in the display window (5゛). Then, when entering the bonus game, the fourth reel (3') is rotated, and as in the embodiment, when the start lever (2) is pressed, an appropriate random delay is applied and the fourth reel (3') is rotated. )
It is to stop it. The motor for rotating the fourth reel (3') and the reel position detection means for determining the stop position, that is, the symbol displayed on the display window (5'), are the same as those for the other three reels (3). .

In the above embodiment, the start lever (2) is also used as the lottery operation tool of the lottery means (8), but it may be provided separately, or the lottery operation tool can be omitted and the start lever (2) can be used for the set time. The lottery may be automatically drawn after a certain period of time has elapsed.

Furthermore, as a lottery means (8), when the combination of symbols becomes a specific combination for the bonus game, a lottery is drawn in advance using a random number generator or the like, and based on a command from a lottery operating tool or after a set time has elapsed. , the lottery results may be displayed.

It should be noted that the present invention is not limited to the structure shown in the accompanying drawings by adding reference numerals in the claims for convenient comparison with the drawings.
