DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball and ball game machine such as a pachinko machine.

[0002]

2. Description of the Related Art In a ball-and-ball game machine such as a pachinko machine, a game board is provided with a variable symbol display means having a plurality of symbol display portions and a start means for detecting entering or passing of a game ball. When the means detects a game ball, the symbol of each symbol display portion of the variable symbol display means is changed for a predetermined time, and when the stopped symbol after the change becomes a specific jackpot symbol, the special winning means is opened and closed a predetermined number of times. Or after the game ball that has won the other prize means passes through the special operation area inside it,
There is a method in which a special jackpot is opened and closed a predetermined number of times each time a game ball wins a specific starting means, and a jackpot right advantageous to the player is generated to return profits.

In the CR machine, when the stop symbol of the variable symbol display means stops at the big hit symbol and a big hit occurs,
There is a probability variation type in which the probability of occurrence of a jackpot from the next time is switched to a high probability of about 10 times.

[0004] In this type of ball game machine, once a big hit occurs on the fluctuating symbol display means side, a large number of game balls win the big prize means while the big prize means repeats the opening and closing operations thereafter. A great deal of profit is returned to the player, and in a probability-variable ball game machine, once a jackpot occurs, the state becomes a high-probability state, so that the jackpot is likely to continue to occur. For this reason, there is an advantage that the player can play a game while expecting a great return profit, and the popularity of the player is high.
At present, it is widely used in many game stores.

[0005]

In a conventional ball-and-ball game machine, a random number generating means sequentially generates a jackpot random number, a reach random number, and other outlier random numbers at a predetermined probability.
When the starting means detects a game ball, a random number control method is used in which the random number generated by the random number generating means is randomly selected by the random number lottery means, and the symbol of the variable symbol display means is varied by the variation processing means for a predetermined time in accordance with the random number. ing.

Accordingly, aside from whether or not a big hit actually occurs during the game, the starting means detects the game balls for the set number of times and the changing symbol display means changes the number of times for the set number of times. Is repeated, a big hit occurs with a predetermined set probability. However, there are few conventional ball game machines, whether a normal machine or a CR machine, that incorporate a thoughtful expression into the display form of the variable symbol display means. It is not in the form of playing games interactively while thinking. Therefore, the player simply fires the game ball until a jackpot occurs, and it takes a long time for the initial jackpot to be monotonous and interrupts or abandons the game due to the impatience during that time Sometimes.

In particular, in some ball game machines such as CR machines, the continuous occurrence rate of jackpots is higher than that of ordinary machines, but the occurrence probability of initial jackpots is set to be reduced to about half.
Accordingly, it is becoming more and more difficult to generate an initial jackpot. The present invention has been made in view of such conventional problems,
Provide a ball-and-play machine that allows players to directly or indirectly grasp the number of reach symbols appearing up to the occurrence of a jackpot, estimating the timing of the jackpot occurrence, and allowing the player to play interesting games while using their thinking power The purpose is to do.

[0008]

According to the first aspect of the present invention, a game board 5 includes a starting means 24 for detecting a game ball fired on the game board 5, and a plurality of symbol display sections 38. A variable symbol display means 35 having a random number generation means 40 for repeatedly generating a random number including a jackpot random number and a plurality of reach random numbers in a predetermined order; and a random number generation means upon detection of the starting means 24.

It is attached detachably. An opening 13 is formed in the back mechanism plate 12, a prize ball tank 14 and a prize ball tank rail 15 are provided on the upper side, a ball payout means 16 is provided on one side, and a passage unit 17 and the like are provided on the lower side. Have been.

The opening 13 is fitted with a back cover 18 and a winning ball tank 19 which are mounted on the back side of the game board 5 vertically close to each other. A control box 20 is detachably attached to the back cover 18 from the back side, and the control box 20 houses a control board. As shown in FIG. 3, a guide rail 22 is annularly mounted on the game board 5, and a display unit 23, a starting means 24, and a winning opening are provided inside the guide rail 22.
25, an upper left winning opening 26, a left middle winning opening 27, a specific winning means 28, a center winning opening 29, a third kind starting means 30, a large winning means 31, a sleeve winning opening 32, and an out opening 33 are provided respectively.

The display unit 23 has a game information display means 34 and a variable symbol display means 35 incorporated in a display case 37 having an eave portion 36, and a winning opening is provided above the eave portion 36.
25 are provided. The game information display means 34 is configured by a liquid crystal display, and various kinds of games, such as displaying the number of appearances of the reach symbol of the variable symbol display means 35 thoughtfully or displaying other lucky information, as described later, It displays information.

The variable symbol display means 35 has three symbol display portions 38 in the left-right direction, and when the starting means detects a game ball,
The display symbol of each symbol display section 38 is configured to fluctuate for a predetermined time by random number processing. In addition, each symbol display unit 38 is configured to variably display, for example, 16 types of symbols 0 to 9 and A to F in that order.

The specific winning means 28 is activated when the stop symbol of each symbol display section 38 of the variable symbol display means 35 is a specific jackpot symbol such as "7.7.7", and its opening / closing plate is opened. It is configured as follows. Then, this specific winning means 28
Is divided into three parts, the center of which is a special operating area 39.
It has become.

FIG. 4 shows a control system. Numeral 40 is a random number generating means, which is configured to generate a random number from 0 to 255 repeatedly when the probability of occurrence of a jackpot is 1/256, for example. The random numbers generated by the random number generation means 40 include:
Fifteen reach random numbers are set in addition to the jackpot random numbers, and the others are off random numbers.

Reference numeral 41 denotes random number lottery means. When the starting means 24 detects a game ball, the random number value of the random number generation means 40 at the time of the detection is randomly selected. Reference numeral 42 denotes a random number determining means, which determines whether the random number drawn by the random number drawing means 41 is a jackpot random number, a reach random number, or an out-of-range random number.
After each of the 35 symbol display sections 38 stops at the big hit symbol, the specific winning means 28 is enabled and the special operation area 39 is enabled.

Reference numeral 43 denotes a fluctuation processing means. Each symbol display section 38 of the fluctuation symbol display means 35 when the starting means 24 detects a game ball.
Is varied for a predetermined time, and when the random number drawn by the random number lottery means 41 is a jackpot random number, for example, the stop symbol of each symbol display section 38 becomes a jackpot symbol of "7.7.7". The stop symbol of each symbol display unit 38 is controlled according to the random number, the reach random number, and the out-of-order random number.

In the case of the reach random number, among the three symbols displayed on the symbol display section 38, only the reach symbol different from the display symbol on the right symbol display section 38 is displayed. All of the symbols displayed on the symbol display section 38 are different from each other.

Reference numeral 44 denotes a right generating means, and a variable symbol display means 35.
In the event of a jackpot where the stop symbol of the symbol display section 38 becomes a jackpot symbol, this is for generating a right advantageous to the player, and the random number determination means 42 determines that it is a jackpot random number, the specific winning means 28 becomes effective, When the game ball passes through the special operation area 39, the large winning means 31 is opened and closed up to 16 times each time the game ball enters the third type starting means 30. The large winning means 31 is configured to close when ten game balls have won in one open state.

Numeral 45 is a counting means, which counts the number of times the reach symbol appears on the symbol display part 38 of the variable symbol display means 35 by the signal when the random number judging means 42 has selected the reach random number by the time the big hit occurs. It has become. 46 is an expected number calculating means for calculating the expected number of continuous jackpots according to the counting result of the counting means 45 after the occurrence of the initial jackpot. That is, when the reach symbol is assumed to be 15, when the reach symbol is assumed to be 15, the jackpot is generated once for every 16 appearances of the reach symbol. After subtracting the standard number of times 16 for each occurrence, the result is divided by the standard number of times 16 and rounded off to calculate the expected number of continuations. For example, if the number of appearances of the reach symbol is 45, the expected number of continuations after the occurrence of the first big hit is two.

Numeral 47 denotes a display data storage means. When picture images such as those shown in FIGS. 5A to 5E are intermittently displayed at predetermined times according to the number of appearances of the reach symbol, each picture image is displayed. Data A to E are stored together with other display data. Reference numeral 48 denotes a display control means, which controls the count result of the counting means 45 to be thoughtfully displayed on the game information display means 34 so that the display state of the game information display means 34 changes according to the count result of the counting means 45. When the count value of the counting means 45 exceeds a predetermined value, for example, 10, the expected number of continuations calculated by the expected number calculating means 46 is displayed on the left corner of the screen of the game information display means 34 or the like. In this embodiment, the game information display means 34 also serves as the expected number display means.

The display control means 48 extracts the data stored in the display data storage means 47 and changes the display image of the game information display means 34 to the picture images A to The game information display means 34 is controlled so as to change in the order of E. Of course, the display control means 48
The storage data of other game information is extracted as necessary from the display data storage means 47, and the game information is displayed on the game information display means.
It also has a function to display it on the 34.

The picture images A to E are described in "Urashima Taro Story".
The picture A is a scene where the main character Taro Urashima helps a turtle being bullied by a child, and the picture B is a scene where a turtle helped by Taro Urashima goes to Ryugu Castle. , Picture image C is a scene in which Taro Urashima arrives at Ryugu Castle and enjoys the treats of Otome-sama etc. in front of the treat. Picture image D is a picture of Taro Urashima, who continued to play after forgetting the passage of time. The picture image E is a scene where you receive a souvenir box from Tate, picture image E is a scene where when returning Urashima Taro opens the box, the smoke rises from the box and immediately becomes an old man, and each of these picture images A to E is Each is composed of a moving image.

Next, the operation will be described with reference to the flowchart of FIG. If the power of the pachinko machine 1 is turned on, the random number generation means 40 constantly counts clock pulses repeatedly to generate random numbers from 0 to 255. At the time of the game, the operating handle 11 of the firing means 10 is operated in a state where the game ball is put in the upper plate 7. Then, in conjunction with the firing operation of the firing means 10, the game ball of the upper plate 7 is moved to the firing position of the firing rail by one.
The game balls are supplied one by one, and are hit with a hitting hammer and sequentially fired along the guide rails 22 on the upper side of the game board 5.

The game ball fired on the upper side of the game board 5 is
While falling along the surface of the game board 5, the player wins the winning prize port 25 or the like, or falls to the lower part of the game board 5 and out port 33.
And pass behind the game board 5. When the game ball passes through the starting means 24 below the fluctuating symbol display means 35 from top to bottom, and the starting means 24 detects a game ball (step S
1) Since the random number generation means 40 constantly repeatedly generates a random number from 0 to 255, the random number lottery means 41 selects the random number at that time (step S2), and at the same time, the random number is determined by the random number determination means 42. It is determined whether the random number is a jackpot random number, a reach random number, or an out-of-range random number (step S3).
38 symbols are varied (step S4).

At this time, the fluctuation processing means 43 is connected to each symbol display unit.
After the symbol 38 fluctuates for a predetermined time, the fluctuating symbol display means 35 is controlled according to the determination result determined by the random number determination means 42.
For example, if the random number is a big hit random number, the stop symbol of each symbol display unit 38 is a big hit symbol such as “7.7.7”, and if it is an outlier random number including a reach random number or the like, each symbol display unit 38 The stop symbol displays the off symbol including the reach symbol. The symbols on each symbol display section 38 stop sequentially from the left after a predetermined fluctuation time has elapsed.

In accordance with the result of the random number judgment by the random number judgment means 42, the following operation is performed. When the lottery random number is a jackpot random number (step S5), the specific prize means 28 is enabled (step S6). If the game ball which has won the specific prize means 28 passes through the special operation area 39 (step S7), the right is generated. The means 44 operates to generate a right (big hit state) advantageous to the player (step S8).

That is, once the game ball passes through the special operation area 39 of the specific winning means 28, thereafter, every time a game ball enters the third kind starting means 30 (step S9), the special winning means 31 is opened for a certain time. Then, the special winning means 31 repeats the opening and closing operation up to 16 times (step S11).

For this reason, since ten game balls win during one opening of the special winning means 31, one opening ball is opened and closed 16 times.
60 game balls are won, and the ball payout means 16 pays out 15 game balls for a total of 2400 game balls for each of the game balls, giving a great profit to the player.

When the result of the determination is a reach random number (step S12), a reach symbol appears on each symbol display section 38 of the variable symbol display means 35.
The signal from 42 is counted and stored (step S13). Therefore, each time a reach symbol appears on each symbol display section 38 of the variable symbol display means 35, the counting means 45 sequentially counts the number of appearances.

Then, the display control means 48 determines the number of appearances of the reach image, and every time the number of appearances increases, for example, five times (step S14), the display control means 48 extracts the data stored in the display data storage means 47. (Step S15), the picture images A to E are displayed on the game information display means 34 for only one moment in the order in which the reach symbol appears five times (step S15).
16).

For this reason, the game information display means 34 always displays other game information as an image, but the variable symbol display means 35
Each time the reach symbol appears five times on the symbol display section 38, each of the picture images A to E is sequentially displayed for one moment in the middle of the image display of the game information display means 34.

Each time the counting means 45 counts the number of appearances of the reach symbol, the expected number calculating means 46 calculates the expected number of continuous big hits. Then, after the occurrence of the first jackpot, the counting means 45
When the count value of “” exceeds “10”, each time a reach symbol appears, the expected number of continuations of the jackpot is numerically displayed on the game information display means 34 for a certain period of time. The expected number of continuations is 0
In the case of the number of times, the number of times is not displayed.
If the determination result is a non-reach random number other than the reach random number (step S17), the process returns to step S1.

As described above, each time the reach symbol appears on the fluctuating symbol display means 35 a predetermined number of times, the game information display means 34 sequentially displays the unified picture images A to E, so that a hit until a jackpot occurs. It is possible to embody an expression that expresses a change in game state thoughtfully. Therefore, it is possible to evoke the thinking ability of the player, and the player can interactively think about the change in the game state of the pachinko machine while watching the appearance status of the picture images A to E, and play the game with fun. The game can be prevented from being monotonous.

That is, each of the picture images A to
If E appears even momentarily, the player playing the game while paying attention to the display of the game information display means 34 can surely catch the change and make some change in the game state of the pachinko machine. Know what happened. Then, the player can interactively think about the timing of the occurrence of the jackpot in the near future from the appearance of each of the picture images A to E or the change of each of the picture images A to E, and the thinking ability of the game is remarkable. improves.

In particular, each of the picture images A to E has one narrative in itself, such as "Urashima Taro Monogatari", and uniformity that makes it easy to predict the next picture image from the previous picture image. Therefore, even if it is inserted in the middle of other game information displayed on the game information display means 34, it can be easily identified and caught.

The number of appearances of the reach symbol with respect to the probability of occurrence of the jackpot is determined at the design stage of each pachinko machine, and the number of appearances of the reach symbol is counted by the counting means 45, and the display state is displayed according to the counting result. Since it is changed, it is possible to sufficiently estimate the timing of occurrence of a jackpot or the like stochastically based on the change in the display state.

However, the probability of occurrence of a jackpot is 1/256.
If the reach symbol appears 15 to 16 times, a jackpot occurs at a rate of about 1 time, but this is a probability even to get tired, and there is a difference in the jackpot occurrence characteristics individually in each pachinko machine. It is another matter whether a jackpot actually occurs. Therefore, even if the picture images A to E are displayed on the game information display means 34 according to the number of appearances of the reach symbol, the pachinko machine 1 is not immediately captured. Moreover, since the number of appearances of the reach symbol is counted by the counting means 45, the count data can be reduced as compared with the case of counting the number of starts of the variable symbol display means 35, and the subsequent processing and control can be easily performed. it can.

On the other hand, the expected number of continuations after the initial jackpot is displayed on the left side of the game information display means 34, so that the player can play the game information display means regardless of before or after the occurrence of the jackpot.
With the display of 34, it is possible to grasp the expected number of continuations of the jackpot and play the game while expecting the occurrence of the jackpot.
In addition, the expected number-of-times calculation means 46 calculates the number of continuous predictions from the number of appearances of the reach symbol, so that the number of predicted continuous times can be easily calculated.

FIG. 7 illustrates a second embodiment of the present invention,
A liquid crystal display 49 having a variable symbol display means 35 and a game information display means 34 provided above and below is provided. In the game information display means 34, a reach symbol appearance number display section 50 and a predicted number display section 51 are arranged on the left and right, and the appearance number display section 50 is provided.
Each time the counting unit 45 counts, the count value is displayed, and the predicted number display unit 51 directly displays the predicted number of continuations calculated by the predicted number calculation unit 46 as a number.

The number of appearances and the number of continuous predictions are displayed for a certain period of time in synchronization with the appearance of the reach symbol or the like, and are turned off after the lapse of the certain period of time. Thus, even when the count value of the counting means 45 is directly displayed on the appearance number display section 50, the change of the display value can sufficiently estimate the timing of occurrence of a jackpot, as in the first embodiment.
In addition, since the predicted number of continuations is displayed on the predicted number display section 51, the player can grasp the predicted number of continuations and play the game while expecting the number.

FIG. 8 illustrates a third embodiment of the present invention,
After the end of the jackpot right by the right generation means 44, the expected number of continuations from the expected number calculation means 46 is displayed in the expected number display means 34.
Is displayed. That is, the expected number calculating means 46 calculates the expected number of continuations every time the counting output is output from the counting means 45. However, the right generation means 44 works due to the occurrence of a big hit in the variable symbol display means 35 and the like, and a right advantageous to the player is generated, and until the right is generated, the expected number of continuations is displayed on the game information display means 34. Do not show. Then, when the jackpot right ends, the display control means 48 operates by a signal from the right generation means 44 at that time, and the game information display means 34 displays the expected number of continuations already calculated by the expected number calculation means 46. This display is for a short time, and is displayed only once.

In this embodiment, since the expected number of continuations is displayed after the right ends, the expected number of continuations is a kind of profit of the player due to the occurrence of the jackpot, and the display of the expected number of continuations shows the player's motivation for the game. Can be further evoked.

Also, since the expected number of continuations is displayed after the end of the right, the benefit of the number of appearances of the reach symbols accumulated during the game of the previous player as in the case of displaying each time the counting output of the counting means 45 is output is obtained. The next player is less likely to receive it immediately, and the imbalance between the preceding and following players can be eliminated. In other words, the number of appearances of the reach symbols accumulated during the game of the previous player remains as the count value of the counting means 45, but unless the jackpot occurs and the right is terminated, the predicted number of continuations does not appear. Player will not immediately benefit from the predicted number of continuations from the game.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment.
For example, in each embodiment, the count value of the counting means 45 and the expected number of continuations of the expected
The game information display means 34 is also used as the expected number of times display means.
34 and the estimated number display means may be provided separately.

The game information display means 34 and the estimated number of times display means may be provided at other positions.
The display form when the counting result is displayed is sufficient as long as it gives an impression to the player, and various expressions based on a change in the display level and the like are possible. When the counting result is displayed on the game information display means 34 every time the reach symbol appears a predetermined number of times, even if all the displays are the same, it is possible to evoke the thinking ability of the player by the strangeness of the display. .

The expected number-of-times calculating means 46 may calculate the number of continuous expected times by another calculation method. In the embodiment, the predicted number of continuations is displayed after the first big hit, but may be displayed before the first big hit. Further, the present invention can be similarly applied to a ball game machine such as an arrangement ball machine in addition to a pachinko machine.
