DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art There is a ball-and-ball game machine such as a pachinko machine, for example, of the probability changing type as described in Japanese Patent No. 2619813.

[0003] In this probability changing type ball game machine, the symbol of the symbol display means fluctuates for a predetermined time on condition that the symbol starting means detects a game ball, for example, and the symbol after the fluctuation becomes a specific mode. , The profit state generating means is operated, and the variable prize means is opened, thereby generating a profit state advantageous to the player.

[0004] When the profit state ends, the probability changing means operates after the predetermined condition is satisfied, and the probability that the symbol after the change becomes the specific mode changes from the normal low probability state to the high probability state. If the symbol display means fluctuates a predetermined number of times in the high probability state, the high probability state is returned to the normal low probability state by the probability return means.

[0005]

In the case of the high probability state, the probability of the specific mode after the fluctuation increases to about 10 times as compared with the ordinary low probability state, so that the profit state occurs again. The likelihood increases and the player can play the game in an advantageous state.

However, according to the conventional probability change formula, there is only one type of high probability mode in the case of the high probability state, and if the condition of the probability change is satisfied, the high probability mode is changed to the high probability state by the one type of high probability mode. Therefore, there is a problem that even in the high-probability state, the change of the game property itself is scarce and the interest of the player is lacking.

The present invention has been made in view of the above-mentioned conventional problems, and provides a ball game machine which can improve the game characteristics by changing the high-probability mode in the high-probability state and increase the interest of the player. Aim.

It is stored in the case.

The main control board 32 mainly controls the game operation on the game board 4 side, and includes a first symbol display means 14 and a first control system 34 for performing processing related thereto.
A second symbol display means 15 and a second control system 35 for performing processes related to the second symbol display means 15 are provided, and each of the control systems 34 and 35 includes a CPU, a ROM, a RAM, and the like. The symbol control board 33 is provided with a first symbol control means 36 and a second symbol control means 37.

The first control system 34 includes at least a first random number lottery means 38, a first judging means 39, a first profit state generating means 40, and a first symbol control command transmitting means 41. The first random number lottery means 38 generates a predetermined number of random numbers in accordance with the probability, such as generating ten random numbers from 0 to 9 when the probability that the first symbol after the change becomes the predetermined mode is 1/10. A random number value is generated, and one of the random number values is randomly selected on condition that the first symbol starting means 16 detects a game ball.

The first judging means 39 is the first random number lottery means 3
The first random number lottery means 38 determines whether or not the first symbol after the change is in a predetermined mode based on the random number value of the random number in Step 8, ie, whether to generate the first profit state. It is determined whether or not the lottery random number value is a predetermined mode determination value (first profit state determination value), and when the random number value is the predetermined mode determination value, the determination output of the predetermined mode (first profit state occurrence) is determined. Is issued. Note that the first determination unit 39 determines that the first
It constitutes a profit state determination means.

The first profit state generating means 40, based on the fact that the first symbol after the change of the first symbol display means 14 becomes the predetermined mode when the first determining means 39 determines the predetermined mode, a game. A first profit state that is advantageous to the user is generated, and the opening / closing claw 29 of the second symbol starting means 17 is opened for a predetermined time.

When the first symbol starting means 16 detects a game ball, the first symbol control command transmitting means 41 sends a stop symbol command or the like of the first symbol in one direction based on the determination result of the first determining means 39. The information is transmitted to the symbol control board 33 by communication to instruct the fluctuation and stop of the first symbol.

The second control system 35 includes at least a second random number lottery means 42, a second determination means 43, and a specific mode selection means 44.
And non-specific mode selecting means 45 and second profit state generating means 46
And a probability changing means 47, a probability returning means 48, and a second symbol control command transmitting means 49.

The second random number lottery means 42 generates a predetermined number of random numbers in accordance with the probability that the changed second symbols 25a to 25c are in a specific mode, and the second symbol starting means 17 detects a game ball. Under such a condition, any one of the random numbers is randomly selected.

The second determination means 43 is a second random number lottery means 4
The second symbols 25a to 25 after the fluctuation based on the random number value of the lottery in Step 2
25c is used to determine whether or not the specific mode is selected, that is, whether or not to generate the second profit state, and the lottery random number value selected by the second random number random selection means 42 is determined by the specific mode determination value (the second mode). It is determined whether or not the random number value is a specific mode determination value, and a determination output of a specific mode (second profit state occurrence) is output when the random number value is a specific mode determination value. Note that the second determination unit 43 forms a second profit state determination unit.

When the second judging means 43 judges that the second symbol 25a to 25c has changed, the second symbol 25a to 25c indicates "7.7.
This is for generating a second profit state that is advantageous to the player based on a specific mode such as “7”.

The second profit state generating means 46 opens the opening / closing plate 30 of the variable winning means 18 after the second symbols 25a to 25c after the fluctuation of the second symbol display means 15 are in a specific mode. When a predetermined time has elapsed since the opening and closing of the opening and closing plate 30, or when a predetermined number of game balls have been won in the variable prize means 18 by the elapse of the predetermined time, the opening and closing plate 30 is closed. , The opening and closing operation is continued up to a predetermined number of times (for example, 16 times).

The specific mode selection means 44 includes the second determination means 4
When the determination result of No. 3 is a specific mode determination, one of a plurality of types of specific modes is selected by random number lottery, and the type of the stop symbol in which the changed second symbols 25a to 25c are in the specific mode is set. It is for doing. Non-specific mode selection means 4
5, when the determination result of the second determining means 43 is other than the specific mode determination, one of a plurality of types of non-specific modes is selected by random lottery, and the changed second symbols 25a to 25c are non-specific. This is for setting the type of stop symbol in a specific mode. In the non-specific mode, at least one of the three symbols is a different symbol.

Since the second symbols 25a to 25c use numeric symbols from 0 to 9, the second symbols 25a to 25c are used.
The specific mode of 5c includes a plurality of types of special modes that are a specific mode in a special design, and a plurality of types of non-special modes that are a specific mode of a non-special pattern. The specific mode selection means 44 performs lottery by random numbers.

The probability changing means 47 determines that the second determining means 43 has determined the specific mode, and the changed second symbols 25a to 25c
Changes the probability that the second symbols 25a to 25c become the specific mode after the end of the second profit state from the normal probability (low probability) to the high probability, on condition that High probability mode setting means 50
Having. When the probability is high, the probability changing unit 47 increases the number of specific mode determination values when the second determining unit 43 determines whether the mode is the specific mode.

The high-probability mode setting means 50 is for setting the high-probability modes A and B in a high-probability state. One of a plurality of types of high-probability modes A and B is selected according to the type of the special mode. One of them is selected and its high probability mode A,
B is set as the probability at that time.
For example, when the normal probability is 1/320, there are a plurality of types of high probability modes, a high probability mode A having a probability of 1/50 and a high probability mode B having a probability of 1/80. Are one or more special modes ("3.3
In the case of "3" and "7.7.7" in the odd pattern, the high probability mode A is changed to one or more other special modes ("1.1.1", "5/5. 5) The high probability mode A or B corresponding to the special mode is selected and set, for example, when the odd mode of “9 • 9 • 9” is selected, the high probability mode B is selected alternatively. It is configured to be.

When the predetermined condition is satisfied, the probability returning means 48, for example, outputs the second symbol 25a after the next change.
-25c is a specific mode other than the special mode (non-special mode), and when the second profit state in the specific mode occurs,
The probability of the second determination means 43 is returned from the high probability state to the low probability state of the normal probability.

When the second symbol starting means 17 detects a game ball, the second symbol control command transmitting means 49 determines whether the specific pattern selecting means 44 or the non-specific specific selecting means 45 has determined the result of the second determining means 43. Based on the selected stop symbol or the like, the variation pattern commands of the second symbols 25a to 25c,
A stop symbol command, a stop command, and the like are transmitted to the symbol control board 33 by one-way communication, and the second symbols 25a to 25a are transmitted.
5c is commanded to change and stop.

The first symbol control means 36 controls the first symbol display means 14 based on a command from the first symbol control command transmission means 41 on condition that the first symbol starting means 16 detects a game ball. Change the first symbol for a predetermined time,
The first symbol is stopped in a predetermined mode when the determination result of the determination means 39 is a predetermined mode determination, and in a non-predetermined mode otherwise.

The second symbol control means 37, based on a command from the second symbol control command transmission means 49, provided that the second symbol starting means 17 detects a game ball. The second symbols 25a to 25c are varied in a predetermined variation pattern or the like for a predetermined time, and the second symbol 25a is in a specific mode when the determination result of the second determination means 43 is a specific mode determination, and in a non-specific mode otherwise. To 25c are stopped.

Next, the operation of the pachinko machine will be described. When a game ball is fired by the shooting means 9 during a game, the game ball enters the game area 12 via the guide rail 11 and then falls into the game area 12 while dropping in the game area 12. , Dropping downward while passing through the first symbol starting means 16. When the game ball passes through the first symbol starting means 16, the first random number lottery means 3
8 randomly selects the generated random number value, and the first determination means 39 determines from the random number value whether or not it is in a predetermined mode (the occurrence of the first profit state).

When the result of the judgment by the first judging means 39 is a predetermined mode judgment, the first symbol of the first symbol display means 14 fluctuates for a predetermined time and then stops in a predetermined mode. The first profit condition occurs and the second
The opening / closing claw 29 of the symbol starting means 17 is opened for a predetermined time, so that a game ball can easily win the second symbol starting means 17. If the determination result of the first determination means 39 is other than the predetermined mode determination, the first symbol after the change stops in the non-predetermined mode.

When the opening / closing claw 29 of the second symbol starting means 17 is opened and a game ball wins, and the second symbol starting means 17 detects a game ball, the second random number lottery means 42 randomly selects the generated random number value. The second determination means 43 determines whether or not the specific mode is selected from the random number value of the lottery, and the specific mode selection means 44 or the non-specific mode selection means 45 determines the second symbol 25 a
The type of the stop symbol after the fluctuation of 〜25c is set, and the second symbol control command transmitting means 49 transmits the fluctuation pattern command, the stop symbol command, and the stop command of the second symbols 25a to 25c by the one-way communication to the symbol control board 33 side. To instruct the second symbols 25a to 25c to change and stop.

The second symbol control means 37 analyzes each command from the second symbol control command transmitting means 49 and, based on the command, analyzes the second symbol 2 of the second symbol display means 15.
5a to 25c are varied for a predetermined time in a predetermined variation pattern or the like, and the second symbols 25a to 25c are changed in a specific mode when the determination result of the second determining unit 43 is a specific mode determination, and in a non-specific mode otherwise. Stop.

When the result of the judgment by the second judging means 43 is a specific mode judgment, the specific mode selecting means 44 selects the changed second symbols 25a to 25c from the numerical symbols 0 to 9 including the odd symbols and the even symbols. Is randomly set by random number selection or the like and set. Then, the second symbol control command transmitting means 49 transmits a symbol command for setting the symbol set by the specific mode selecting means 44 to the second symbols 25a to 25c, whereby the second symbols 25a to 25c change for a predetermined time. After that, it stops at the symbol of the type specified by the symbol command.

For example, when the specific mode selection means 44 designates a special symbol of "3" or "7", the second symbol after the change
Designs 25a to 25c are "3.3.3" or "7.7."
7 ", and when a specific symbol other than" 1 "," 5 "or" 9 "is designated," 1.1.1. "
1 "," 5.5.5 "or" 9.9.9 ". Also, when the specific mode selection means 44 makes an even number of symbols, the changed second symbols 25a to 25c are “2 · 2 ·
2 "and other specific modes.

The second symbols 25a to 25f after the change in this way.
When 25c is in the specific mode, the second profit state generating means 46 operates to generate the second profit state, and the opening / closing plate 30 of the variable winning means 18 is opened forward. Variable winning means 1
In 8, when the predetermined time has elapsed from the opening or when a predetermined number (for example, 10) of game balls are won within the predetermined time, the opening / closing plate 30 is closed at that time. When the winning game ball passes through the specific area 31, the open / close plate 30 is opened again,
The opening and closing operations are repeated up to a predetermined number of times (for example, 16 times).

For this reason, if the second profit state occurs, there is a possibility that a large number of game balls will be won in the variable winning means 18, and the player will receive a prize ball according to the number of the winning balls. And can enjoy tremendous benefits.

The second symbols 25a to 25c after the change are "3.
When the specific mode is set in the special mode of “3.3” or “7.77.7”, the probability changing unit 47 is activated after the end of the second profit state generated thereby, and the specific mode determination value of the second determining unit 43 is determined. And change the probability from the normal low probability state to the high probability state.

In this case, the changed second symbols 25a to 25a
Depending on whether c is “3.3.3” or “7.7.7”, or “1.1.1”, “5.5.5” or “9.9.9”, The high probability mode setting means 50 selects and sets either the high probability mode A or the high probability mode B. For example, the second symbols 25a to 25c after the change are “7 ·
7.7 ”, the high probability mode A is changed to“ 1.1.1 ”
, The high probability mode B is selected. Then, when the second symbols 25a to 25c are in the specific mode of “7 / 7,7”, the second determining unit 43 thereafter determines with a probability of 1/50 whether or not the specific mode is used. Further, when the specific mode of “1.1.1” is reached, it is determined with a probability of 1/80 whether or not to use the specific mode.

Therefore, the changed second symbols 25a to 25c
Is a specific mode in any one of a plurality of special modes and satisfies the condition of probability change, a large difference occurs in the high probability state depending on the type of the special mode, and then the second profit state occurs again Since there is a great difference in the possibility of whether or not to play, it is possible to improve the game characteristics as compared with the conventional method of changing the probability to one type of high probability mode. For the player, the second symbols 25a to 25c after the change
It is of interest not only whether is a special aspect of a particular aspect, but also what kind of special aspect it is,
Along with the improvement of the game property, the interest of the player can be further increased.

When the second symbols 25a to 25c after the change become the specific mode again, if the specific mode is the special mode, the probability changing means 47 continues the high probability state. However, when the specific mode is a non-special mode (specific mode in an even symbol), the probability return means 48 operates to return the probability from the high probability state to the normal low probability state.

The probability returning means 48 may return to the low probability state at the time of occurrence of the second profit state,
It may be after the end of the second profit state. During the occurrence of the second profit state, if the second symbols 25a to 25c of the second symbol display means 15 do not fluctuate, it is substantially possible to return to the low-probability state at the time of occurrence or end of the second profit state. Is the same as However, even during the occurrence of the second profit state, the second symbol 25a
２５25c fluctuates to a specific mode when the second
In the case where the next second profit state is generated after the profit state ends, the profit of the player differs depending on whether the second profit state is returned to the low probability state at the time of occurrence or the end time. The return point may be selected under some conditions.

When the high probability mode setting means 50 of the probability changing means 47 selects and sets either the high probability mode A or the high probability mode B, the liquid crystal display 23 of the liquid crystal display means 13
The high-probability notifying means 26 displays the high-probability mode A or the high-probability mode B in characters and other display forms to notify the player. For this reason, the player can use the high probability informing means 26.
, It is possible to play the game while grasping that the high probability mode at that time is the high probability mode A or the high probability mode B.

In this case, the high-probability notifying means 26 initially displays a character or other large image to impress the player, such as "probable change in the high-probability mode A", and after a predetermined time, the liquid crystal display unit 23 May be displayed until the end of the high probability state by, for example, emitting or blinking a part of the display area.

The high-probability notifying means 26 is activated when the second symbols 25a to 25c after the change become a special mode, or when the high-probability mode setting means 50 is operated, and the predetermined high-probability mode A, The information may be displayed at any time when the state becomes the high probability state in B.

FIG. 5 illustrates a second embodiment of the present invention. In this embodiment, the probability return means 48 is provided with a change number counting means 51 for counting the number of changes of the second symbols 25a to 25c of the second symbol display means 15, and the probability has changed from the low probability state to the high probability state. After that, when the fluctuation number counting means 51 has counted the fluctuation of a predetermined number of times (for example, about 80 times), the high probability state is returned to the low probability state. The change number counting means 51 counts the number of changes of the second symbols 25a to 25c based on the detection of the game ball by the second symbol starting means 17, and the like. Other configurations are substantially the same as those of the first embodiment.

As described above, the probability may be returned from the high probability state to the low probability state based on the number of times the second symbols 25a to 25c change. In this case, as shown in FIG. 6, the liquid crystal display section 23 of the liquid crystal display means 13 is provided with a change number notifying means 52 in addition to the high probability notifying means 26, and the change number notifying means 52 controls the high probability mode at that time. A, B
May be notified of the number of times of change. Note that the change number notifying unit 52 may display the number of actual changes, or may display the remaining change number.

FIG. 7 illustrates a third embodiment of the present invention. In this embodiment, one or a plurality of display lamps 53 are provided on the display case 22 of the liquid crystal display unit 13 (or the second symbol display unit 15) as the high probability notification unit 26, and the display lamp 53 emits light or blinks. The high-probability state is reported by emitting light. When the high-probability mode A and the high-probability mode B are notified by the common display lamp 53,
It is desirable that the difference between the high-probability modes A and B can be easily identified by changing the blinking cycle or the like. Other configurations are substantially the same as those of the first embodiment.

When the high-probability notifying means 26 is constituted by using the display lamp 53, the display lamp 53 may be provided on a game component such as the liquid crystal display means 13 or directly on the game board 4. May be. The display lamp 53a (see FIG. 1) on the upper side of the front frame 3 is used as a high-probability notifying means 26, and is provided at an appropriate position on the front side of the game machine main body 1 including the front frame 3, the glass door 5, and the like. Is also good.

FIG. 8 illustrates a fourth embodiment of the present invention. In this embodiment, the probability changing means 47 includes a plurality of types of high probability modes A and B, and the second symbol 25a after the variation is changed.
When .about.25c is a special mode among the specific modes, the random number lottery section 54 of the high probability mode setting means 50 operates to select one of the plurality of types of high probability modes A and B by random number lottery. It is designed to be selectively selected and set. Other configurations are substantially the same as those of the first embodiment.

As described above, the probability changing means 47 uses the random number lottery method to select one of the high probability modes A and B from one of the plurality of types.
One may be configured to select one. In this case, one of the plurality of high-probability modes A and B can be selected at random, so that it becomes difficult for the player to predict the types of the high-probability modes A and B, thereby improving the game characteristics. Can be.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to these embodiments, and various changes can be made without departing from the spirit of the present invention.
