Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a gaming machine equipped with a variable winning device.

[0002]

2. Description of the Related Art As a conventional game machine, when a game ball passes through a specific gate, the universal figure display is displayed and converted, and when the stop symbol is hit, the opening / closing blades of the starting opening are converted to open states for only a short time. On the other hand, when the game ball wins the starting opening, the opening / closing blades of the variable winning device are converted to the open state for a short time, and during that time, when the game ball wins the special winning opening in the variable winning device, the opening / closing blade is opened for a predetermined period. There are known ones that operate to perform a special game with a high winning rate.

[0003]

However, in such a conventional example, since the hit probability of the universal figure display is always constant,
There was a problem that the expectation for the special game did not greatly expand depending on the game state, and the interest in trying to generate the special game was easy because the game itself was monotonous.

An object of the present invention is to provide an effective solution to such problems.

[0005]

[Means for Solving the Problems] Therefore, the first variable display means for variably displaying a symbol based on the detection of the game ball in a specific area, and the starting opening is opened only for a short period when the stop symbol is hit. Equipped with opening and closing means for converting and opening and closing means for converting the variable winning device to the open state for a short period when the game ball wins the starting opening, when the game ball wins the special winning opening in the variable winning device, In a gaming machine that operates the opening / closing means for a predetermined period of time to perform a special game with a high winning rate, a variable display of symbols is performed based on the occurrence of the special game.
When the variable display means and the stop symbol are in a special mode, the first
Probability changing means for converting the probability of hitting the variable display means into a high probability until a predetermined cancellation condition is satisfied.

In this case, the occurrence of a winning ball at the special winning opening is set as a condition for canceling the probability changing means. The probability changing means is a probability up counter means for setting the number of times of increasing the probability for converting the hit occurrence probability of the first variable display means to a high value,
When the winning ball to the special winning opening occurs with the number of sets-
The counter down means for performing 1 and the counter updating means for rewriting the set value of the number of times of up every time the stop symbol of the second variable display means generates a special mode.

The second variable display means is provided with several special modes, and different probability up times are set in correspondence with these special modes. The counter updating means has a function of prohibiting rewriting to reduce the set value of the probability up number.
Counter display means for displaying the number of times the probability is increased is provided. Adjustment means for artificially changing the occurrence probability of the special mode of the second variable display means is added.

[0008]

Operation: The first variable display means performs display conversion based on the detection of the game ball in a specific area, and when this stop symbol hits, the opening / closing means of the starting opening is converted to an open state for a short period of time, and the game is played. It becomes easier for the ball to win the starting opening. When the game ball wins the starting opening, the opening / closing means of the variable winning device is converted to an open state for a short period, and when the game ball wins the special winning opening in the variable winning device during that period, the opening / closing means of the variable winning device opens for a predetermined period. It operates only to play special games with a high winning rate.

On the other hand, while the second variable display means is display-converted based on the occurrence of the special game, the probability of hitting the first variable display means is predetermined through the probability changing means when this stop symbol is in the special mode. It is converted to a high probability until the release condition is satisfied. During this probability increase, opening and closing means of the starting port,
As a result, the opening / closing blades of the variable winning device can be easily converted into the open state, and the chances of continuing the special game increase accordingly, so that the player's expectation can be greatly amplified.

If the generation of a winning ball to the special winning opening is set as a condition for canceling the probability increase, the probability of hitting the first variable display means is maintained at a high probability until the special winning is generated again. Can be done at least one more time with a fairly high probability. If the stop symbol of the second variable display means is set to the number of times of up conversion which is converted to a high probability when the special mode is the special mode, the special game can be easily generated by the number of times of setting the probability of increase. In that case, the display conversion of the second variable display means is performed every time a special game occurs, and if this stop symbol is a special mode, the set value of the number of times of up is rewritten.

Regarding rewriting of the number of times of up, if the second variable display means is provided with several special modes and different probability up times are set corresponding to these special modes,
Depending on the special mode of the second variable display means, the set value of the number of times of up may be smaller than the remaining number of times last time. Therefore, if a function of prohibiting rewriting to reduce the set value of the number of up is added, the player feels dissatisfied. Will not be given.

If a counter display means for displaying the number of times the probability has been increased is provided, the remaining number of times the probability is increased can be easily confirmed, so that troubles with the player can be effectively avoided. By adding adjusting means for artificially changing the occurrence probability of the special mode of the second variable display means, there is an administrative merit that the number of coins output can be easily adjusted for each gaming machine.

When a sphere passing through the specific gate 28 is generated, the number of times the gate switch 36 is turned on (the number of unprocessed spheres) is stored up to a maximum of four. While converting the number of ~ 9 in order,
The symbol conversion is stopped after a lapse of a predetermined time, and when the stopped symbol is a hit number, the opening / closing blades 35 are converted to the open state for a short time.

The stop pattern of the universal figure display 41 is based on a random number value extracted from an updated random number each time ON storage of the gate switch 36 occurs, and when this corresponds to a preset hit value, a hit number, When it is not applicable, it is determined to be an outlier. The random number for the general figure updates 0 to the upper limit value, but since the hit probability of the general figure display 41 is changed according to the game state, the hit value and the low probability of the number corresponding to the high probability (for example, 5/10) The number of hit values corresponding to (for example, 1/10) is stored in the data table, and the hit value at the time of high probability is selected when the probability is increasing, and the hit value at the time of low probability is selected otherwise. .

The variable prize winning device 27 is attached to the game board 25 through the board 44, and as shown in FIG.
A window portion 45 is opened substantially at the center, and a recessed chamber 47 for accommodating a pair of character dolls 46 is provided at the back of the window portion 45 (back side of the substrate 44). Immediately below the front surface of the window portion 45, a winning space that opens upward is formed under the front cover 48 and the lower part of the window frame 49, and a special winning hole 50 in the center and general winning holes 51 on the left and right are defined in the space. 52 is a winning hole (general winning hole) located on the upper part of the board, and an entrance 54 to the recess chamber 47 is formed on both sides by using the covers 53, and a game ball from the entrance 54 is recessed on the back side of the board 44. A guide path (not shown) is formed in the upper part of the chamber 47 leading to the falling hole.

At the entrance 54 to the concave chamber 47, an opening / closing blade 55 which can be converted into a closed state in which a game ball is not received and an opened state in which it is easily received is attached, and a solenoid (see FIG. 5) for driving the opening / closing blade 55 on the back side of the substrate 44. 56) is provided. The open / close blade 55 is converted from the closed state to the open state when the solenoid 56 is turned on, and is returned from the open state to the closed state when the solenoid 56 is turned off.

Then, the game ball that enters from the entrance 54 while the blades 55 are opening falls from the guideway to the inside of the recessed chamber 47 between the character dolls 46, and the front surface of the ball receiver 46a in accordance with the operating state of the doll 46. It rolls to the side and wins either the general winning opening 51 or the special winning opening 50 just below the window 45.
A special switch (57 in FIG. 5) for detecting a winning ball is provided at the special winning opening 50, and a count switch (58 in FIG. 5) for totaling the winning balls to the general winning opening 51 and the special winning opening 50 is provided on the back side of the substrate 44. Is provided.

The character doll 46 is always driven at a predetermined speed by a motor (not shown) on the back side of the substrate 44 regardless of the game state, and the doll 46 as a whole moves up and down along the axis 46b and the ball receiver 46a moves. By swinging around the pin 46c, the game ball is changed in a predetermined cycle from a state where it is difficult to guide the game ball to the special winning opening 50 to a state where it is easy to guide it.

The opening / closing blades 55 are once each time the start switch 37 is turned on when the game ball wins the start opening 30, and twice each time the start switch 38 is turned on when the game start prize is won. When the game is converted to the open state and the special switch 57 is turned on to shift to the big hit operation, the opening / closing operation is repeated until a predetermined stop condition is satisfied, and a special game with a high winning rate is generated.

On the surface of the cover 48, in addition to the variable display 60, a counter display 61 (consisting of 10 LEDs) for displaying the number of times of probability increase of the universal figure display 41 is provided. When the winning ball to the special winning opening 50 is generated, the variable display 60 converts and displays the numbers (symbols) 0 to 9 unless the special game is in progress, and stops the symbol conversion after a lapse of a predetermined time. This stop symbol is based on the random number value extracted from the updated random number when the special switch 57 is turned on, and in this example, when the random number value is 7, it is a hit number 7, and when it is 3 or 5, it is a hit number 3, 7, 5 , 3 is an odd number other than 3, and the odd number is an odd number (a number other than 7, 3, 1).

When the stop symbol is the winning number 7, the probability up number 5 is set, when the winning number is 3, the probability up number 3 is set, and when the winning number is 1, the probability up number 1 is set in the up counter. The counter display 61 displays the number of sets with an LED. When this probability up counter is set, when the special game is finished, the hit probability of the universal display 41 is converted into a high probability, and when a winning ball to the special winning opening 50 occurs again during the normal game, Along with the subtraction (-1) of the probability up counter, the hit probability of the universal figure display 41 is returned to a low probability prior to the start of the special game.

At that time, the symbol variation of the variable display 60 is started by the occurrence of the special winning as in the last time, and the probability up counter is set when the stopped symbol is hit, but the number is set smaller than the remaining number of times last time. Since the rewriting to the value is prohibited, for example, when the remaining number is 4, the new number of ups is not set to 3 or 1. As this rewriting process, each time the variable display 60 hits, a new up count is simply added to the previous remaining count, or resetting of the up counter is prohibited until the previous up count becomes zero. You can

The variable display random number is updated from 0 to the upper limit value, but when the adjusting device 62 of the accessory control circuit 20 is operated to change the probability of occurrence of the number (7, 3, 1) for each, for example, 7 1/10, 1/20, 1 as the occurrence probability of
/ 30, 3 as probability of occurrence 2/10, 2/20, 2 /
The probability of occurrence of 30, 1 is 4/10, 8/20, 14 /
When set to 30, the upper limit value of the update random number is 9, 19, 29
It changes to.

In response to signals from the switch 57, the count switch 58, the hit probability adjusting device 62 of the variable display 60, etc., the universal display 41 of the starting opening 31, the memory display 40 and the opening / closing blade solenoid 39, the variable winning device. The operation of the variable display 60 of 27, the counter display 61, the open / close blade solenoid 56 and the like is controlled. In addition, various lamps and LEDs are used for the game status indicator 65.
Summarize as.

Sound generator for playing, 111 for amplifier, 11
2 is a speaker.

Next, the control content will be described with reference to the flowcharts of FIGS. FIG. 6 shows the main routine, FIG.
18 is a subroutine, which starts when the power is turned on. As shown in FIG. 6, the main routine executes random number updating processing, variable display processing, general / universal / universal processing, and game processing (1.01 to 1.04).

In the random number updating process, the variable display random number is updated as shown in FIG. 7, and the upper limit value of the updated random number corresponding to the setting value of the adjusting device 62 is extracted (2.01, 2.0).
2). When the setting value of the adjusting device 62 is 7, the occurrence probability is 1/10,
When the occurrence probability of 3 is 2/10 and the occurrence probability of 1 is 4/10,
9 is taken out as the upper limit value, and every time the updated random number reaches the upper limit value 9, the random number is returned to the initial value 0 (2.03, 2.0
4). The variable display random number is updated from 0 to 9, but when the upper limit value of the updated random number is changed to 19 and 29 by operating the adjustment device 62, the occurrence probability of 7 is 1/20 and 1/30.
The probability of occurrence is 2/20 and 2/30, and the probability of occurrence of 1 is 8
It changes to / 20 and 14/30 respectively.

Further, the universal random number is updated, and the updated random number is returned to the initial value 0 every time the random number reaches the upper limit value (2.05 to 2.07). The upper limit of the update random number is, for example, 9
However, since the number of hit values is increased from 1 in the low probability state to 5 in the high probability state while the probability of the figure display 41 is increasing, the hit probability is reduced from 1/10 to 5/10. To be converted. Note that the hit probability of the universal figure display 41 is the same as the hit probability of the variable display 60.
You may make it changeable by operating.

The variable display processing is for controlling the variable display 60 of the variable winning device 27, and as shown in FIG.
When a special ball 57 is detected by the special switch 57, if the special game is not in progress, the display conversion of the variable display 60 is started and the variable display update random number is extracted (3.01 to 3.01).
3.05). When the random number value is 7, the stop symbol is hit to the number 7, when the random number value is 3 or 5, the stop symbol is hit to the number 3, and when the random number value is an odd number other than 7, 5, 3 the stop symbol is When the random number is an even number, it is determined to be an outlying number (a number except 7, 3, 1) (3.06 to
3.12). Then, the display conversion is stopped with the determined symbol after the lapse of a predetermined time, the probability increase number is 5 when the stop symbol is a hit number 7, and the probability increase number is 3 when the stop symbol is a hit number 3. In addition, when the stop symbol is a hit number 1, the probability up number is set to 1 (3.01 → 3.13 to 3.20).

This processing is performed every time the variable display 60 performs display conversion. When the new number of ups is 3 or 1, the new number of sets is larger than the remaining number of the previous time as compared with the remaining number of the previous time. Only at this time (if the number is small, the previous remaining number is retained), the set number is rewritten (3.18, 3.20).

The normal / universal processing is the specific gate 2 as shown in FIG.
When the passing sphere of 8 is generated, the number of ON memories of the gate switch 36 is added (+1), and the update random number for universal figure is extracted (4.01 to 4.03). After that, the normal operation, the conversion operation, the hit operation, and the out-of-motion operation of the universal figure are executed by processing branch (4.04 to 4.08). Figure 10 for normal operation
When the ON memory of the gate switch 36 occurs,
The hit value at the time of high probability when the hit probability of the public figure is increasing, while the hit value at the time of low probability is taken out at other times, the stop pattern when the extracted value of the update random number for the public figure corresponds to the hit Hit a number, and if it is not applicable, set a deviating number in the stop design (5.01 to 5.08). Then, at the same time as the subtraction of the number of ON memories (-1),
The display conversion of 1 is started (5.09, 5.10).

In the conversion operation, as shown in FIG. 11, the display conversion of the general-purpose display 41 is stopped at a set number that has already been determined in accordance with a predetermined stop timing (6.01, 6.02). When this stop pattern is a disengagement number, the disengagement operation is performed, and at the time of a hit number, the opening / closing blade solenoid 39 is turned on,
While the opening / closing blade 35 is open, a hit operation such as one-shot sound output is performed (6.03 to 6.05). In the hitting operation, when a predetermined processing time elapses as shown in FIG. 12, the opening / closing blade solenoid 39 is turned off and the operation returns to the normal operation (7.01).
~ 7.03). In the disengagement operation, as shown in FIG. 13, when the predetermined processing time elapses, the normal operation is similarly restarted (801,
8.02).

The game process is the opening / closing blade 5 of the variable winning device 27.
5, the normal operation, the blade operation 1, the blade operation 2, and the big hit operation are performed by the process branch as shown in FIG. 14 (9.01 to 9.05). In the normal operation, as shown in FIG. 15, the blade operation 1 is selected when the start switch 37 is turned on by the winning ball to the starting opening 30, and the blade operation 2 is selected when the starting switch 38 is turned on by the winning ball to the starting opening 31.
The open / close blade solenoid is turned on in accordance with these operation patterns (9.01 to 9.05).

In the blade operation 1, the blade 55 is opened once at a predetermined opening / closing timing as shown in FIG. 16, and returns to the normal operation when a predetermined processing time elapses (10.01 to
10.04). At this time, when the special switch 57 is turned on by the winning ball into the special winning opening 50, the big hit operation is started. At that time, if the probability of the general figure is increasing, the probability of hitting the general figure display 41 is lowered. Along with returning to the probability, the probability up counter is subtracted (-1) (10.0
5-10.08). In the blade operation 2, the blade 55 is opened twice at a predetermined timing as shown in FIG. 17, and when a winning ball to the special winning opening 50 is generated during that time, the same processing as the blade operation 1 is performed (11.01). ~ 11.08).

In the big hit operation, the blades 55 are opened and closed at a predetermined timing as shown in FIG. 18, and the number of times of opening and closing is a specified number (for example, 18 times) or the counter switch 5
When the number of winning balls of the variable winning device 27 detected in 8 reaches a predetermined number (for example, 10), the operation returns to the normal operation, and if the probability up counter is not 0 at that time, the hit probability of the universal figure is increased. (12.01 to 12.06). If a special winning occurs while opening and closing the blade 55, the next big hit operation is newly repeated (12.07 to 12.
09), when the number of continuations reaches a prescribed number (for example, 16 times), it returns to the normal operation with the number of times of opening / closing of the blade 55 or the count value of winning balls as a stop condition regardless of the special winning (12.08 → 12. 01-12.06).

Next, the operation based on such a configuration will be described. In the gaming state, when a passing ball to the specific gate 28 occurs, the display conversion of the universal figure display 41 is started, and the symbol fluctuation is stopped after the elapse of a predetermined time. This symbol variation is repeatedly executed at a predetermined cycle based on the ON memory of the gate switch 36, and when the stop symbol is a winning number, the opening / closing blades 35 of the starting port 31 are converted to the open state for a short time. When the opening / closing wing 35 is opened, the game ball can easily enter the starting opening 31.

When the game ball wins the starting opening 30, once each time the starting switch 37 is turned on, once when the starting ball 31 wins, twice each time the starting switch 38 is turned on. The opening / closing blade 55 is converted into an open state. When a game ball enters the entrance 54 from both hem of the winning entrance 52 while the wings 55 are opened, the game ball falls between the character dolls 46 at the back of the recess 47 from the guide path, and the operating state of the doll 46. Accordingly, the ball is rolled on the ball receiver 46a to the front side to win either the general prize opening 51 or the special prize opening 50 directly below the window 45.

When the special winning opening 50 is won, a special game is generated when the special switch 57 is turned on, and the display conversion of the variable display device 60 is started, and the symbol fluctuation is stopped after a lapse of a predetermined time. . When the stop symbol is the winning number 7, the probability up number 5 is set, when the winning number is 3, the probability up number 3 is set, and when the winning number is 1, the probability up number 1 is set in the up counter.

When the special game is started, the big hit operation of the opening / closing blade 55 is started, and the game balls are successively won from the entrance 54. At that time, the special game ends when the number of times of opening and closing the blades 55 reaches a prescribed number or the count value of the winning balls reaches a predetermined number, but when a special prize occurs during that time, the number of opening and closing of the blades and the count value of the winning balls are cleared. The jackpot operation is performed again. That is, the jackpot operation is repeated a specified number of times on the condition that the special winning is generated during the jackpot operation, and the player can obtain a large number of prize balls during the special game.

When the special game is over, the opening / closing blades 55 are returned to the normal operation, but if the probability up counter is not 0, the hit probability of the universal figure is converted into a high probability. Therefore, when shifting to the normal game, a hit number of the universal display 41 is likely to occur in the high probability state, and the opening / closing blade 35 of the starting opening 31 and thus the opening / closing blade 55 of the variable winning device 27 is frequently converted to the open state. Therefore, the number of opportunities for the game balls to win the special winning opening 50 is greatly increased, and the player can have a great sense of expectation for the special game.

When a winning ball to the special winning opening 50 occurs again during this normal game, the probability up counter is decremented (-
Along with 1), prior to the start of the special game, while the probability of hitting the universal figure is returned to a low probability, the display conversion of the variable display 60 is performed, and when the stop symbol is a hit, the same as the previous time, depending on the hit number. The number of times the probability is increased is set in the up counter. In this example, the number of times the probability is increased is set to 3
In the case of 1, the rewriting to the set number smaller than the remaining number of the previous time is prohibited. Therefore, despite the hit of the variable display 60, the set number of times is less than the remaining number of times until then. There is nothing to give to the player.

As described above, in addition to the expectation that a large number of prize balls can be won when a special game occurs, the variable display 6
If the probability up number is set by a winning number of 0, the special game is likely to continue for at least the up number, so that the interest in the game can be further raised. Also, the number of times the probability is increased is variable winning device 2
Since it is displayed on the counter display 61 of 7, it is possible for the player to easily check the remaining number of times of increasing the probability, and it is possible to fully enjoy the taste of the game without misunderstanding or distrust.

Furthermore, since the probability of each hit of the variable display device 60 can be changed by the key operation of the clerk on the adjusting device 62 on the back side of the game board 25, the number of times a special game is generated for each pachinko machine, that is, a prize ball. There is also a management advantage that the number of coins discharged (number of coins) can be easily adjusted.

In summary, according to the present invention, the first variable display means for variably displaying the symbol based on the detection of the game ball in the specific area, and the starting opening is opened only for a short period when the stop symbol is hit. Equipped with an opening and closing means for converting to a state and an opening and closing means for converting the variable winning device to the open state for a short period when the game ball wins the starting opening, when the game ball wins the special winning opening in the variable winning device, the variable winning In the gaming machine that operates the opening / closing means of the device for a predetermined period to perform a special game with a high winning rate, the second variable display means for variably displaying the symbol based on the occurrence of the special game and the stop symbol in the special mode Since the probability changing means for converting the probability of hitting the first variable display means into a high probability until a predetermined cancellation condition is established is provided, in addition to the expectation that a large number of prize balls can be won when a special game occurs. When hit probability of the first variable display means by the stop symbols of the second variable display means is converted to a high probability, it becomes easy to generate continued special game can further enliven interest in the game.

If the generation of a winning ball at the special winning opening is set as a condition for canceling the probability increase, the probability of hitting the first variable display means is kept at a high probability from the end of the special game until the special winning is generated again. Therefore, the special game can be played at least once again with a high probability.

When the stop symbol of the second variable display means is set to a high probability when the stop symbol is in the special mode, the special game can be easily generated by the set number of times. At that time, each time a special game occurs, the display conversion of the second variable display means is performed, and if this stop symbol is a hit, the set value of the number of times of up is rewritten. Regarding this rewriting, if several special modes are provided in the second variable display means and different probability up times are set corresponding to these special modes, the set value of the up times may be set depending on the special mode of the second variable display means. However, if the function for prohibiting rewriting that reduces the set value of the number of times of up is added, the player will not be dissatisfied.

If a counter display means for displaying the number of times the probability is increased is provided, the remaining number of times the probability is increased can be easily confirmed, so that troubles with the player can be effectively avoided. By adding adjusting means for artificially changing the probability of occurrence of the special mode of the second variable display means, there is an administrative advantage that the number of coins to be paid out can be easily adjusted for each pachinko machine.
