2. Description of the Related Art Conventionally, in general, a ball game machine provided with a variable display device has a special design which fluctuates with a variable display device in accordance with a prize of a ball hitting a starting winning opening, and the display result is predetermined. When a big hit symbol (specific display result) is reached, a specific game state is generated, and when a big hit is made with a predetermined probability variable symbol, a big hit determination (whether a big hit symbol is derived or not) is performed in addition to the generation of the specific game state. Has been proposed, which improves the probability of (i) compared to the normal time (this is referred to as probability variation).
In addition, a ball game machine has been proposed in which a starting winning port is configured with a variable winning ball device and a normal symbol display that changes a normal symbol with a passing of a ball to a passing gate is proposed. I have. In this configuration, when the display result of the normal symbol becomes a predetermined hit symbol, the variable winning ball device is expanded and opened in accordance with the result, so that the hit ball can easily win the starting winning opening compared to the normal case. . Also, in the case of having the ordinary symbol display, the fluctuation time of the ordinary symbol is shortened as compared with the normal time when the predetermined condition is satisfied (hereinafter, this is referred to as time saving).
There has been proposed a game machine which gives a game privilege to increase the frequency of opening and closing the variable winning ball device (winning rate to the starting winning port).

[0003]

By the way, in the variable display device which determines whether or not a specific game state has occurred based on the display result of the special symbol described above, even if a certain variable symbol is set, the big hit determination probability is normally set. (Hereinafter referred to as a low probability) and a probability at the time of a probability change (hereinafter referred to as a high probability) are set, and a large hit is easy (at a probability change) or a large hit is difficult (normally). Time) only one of the game states existed. Further, it has been proposed to provide a player with a time reduction of a normal symbol as a game privilege in accordance with establishment of a predetermined condition. In this case, a start winning opening and the like are constituted by a variable winning ball device and a normal symbol display is performed. A device must be provided, and the configuration of the ball and ball game machine is limited. Also, even if the time reduction of a normal symbol is given to a player as a game privilege, the jackpot determination probability is not improved, and it is not practically easy to make a big hit, so that the player feels unsatisfactory. Was something. However, if the jackpot determination probability is extremely increased, it is too disadvantageous for the game arcade. The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a variable display device that generates a probability variation with a jackpot in a probable variable design, in which the probability is lower than the high probability at the time of the probability variation and usually By setting a medium probability higher than the low probability at the time and giving the medium probability as a game privilege, it will improve the interest of the game without becoming too disadvantageous for the game hall, and of course limit the configuration of the ball game machine An object of the present invention is to provide a ball-and-ball game machine capable of granting a game privilege without performing the same.

[0004]

According to a first aspect of the present invention, there is provided a variable display device, wherein a display result derived on a variable display section of the variable display device is a predetermined specific display result. A first probability improving means for increasing and controlling the probability of deriving the specific display result to a first high probability higher than a normal time in a ball game machine capable of generating a specific game state advantageous to a player when A probability improvement determining means for determining whether or not to improve to the first high probability based on the derivation of the specific display result; and a probability that the specific display result is derived is higher than normal and the first high probability A second probability improving means for controlling the variable display device to a second high probability lower than that of the variable probability display device. To do And butterflies. With this configuration, the probability of deriving the specific display result is set to three types of the low probability at the normal time and the first and second high probabilities. It is possible to diversify, and thus, to enhance the interest of the game without becoming too disadvantageous for the game hall. Further, in the configuration in which the probability improvement control to the second high probability is set as a game privilege,
It is not always necessary to specially provide a component for giving a game privilege such as a normal symbol display, and the cost of parts can be reduced accordingly. In other words, it is possible to provide a configuration in which a game privilege is provided even to a ball game machine that does not have a special component for a game privilege (for example, a normal symbol display, etc.). It is possible to give a game privilege without limiting the configuration.

Further, the invention according to claim 2 is characterized in that the second probability improving means changes the probability in a plurality of stages according to the elapse of a predetermined period during the predetermined period. With this configuration, the probability of deriving the specific display result can be set to four or more types, and the gaming state can be further diversified depending on whether or not a big hit is easy.

It is characterized by doing. With this configuration, after the limiter is actuated, the second game bonus which becomes a game privilege with a lapse of a predetermined period (for example, the number of times of starting).
Since the high probability decreases step by step, it is possible to eliminate monotonous game contents after the limiter is activated.

The special variable display device 40 shown in FIG. 1 is used when a display result derived on the variable display section (special symbol display sections 43 to 45) becomes a predetermined specific display result (big hit symbol). This constitutes an example of the variable display device of the ball game machine of the present invention capable of generating a specific game state advantageous to a player.

Also, in the step of determining the type of the big hit symbol shown in FIG. 3A and the SC4 shown in FIG. 8, it is determined whether or not the first high probability is improved based on the derivation of the specific display result. This constitutes an example of the probability improvement determining means of the present invention.

Further, the probability of deriving the specific display result is higher than the normal time and lower than the first high probability by the probability fluctuation set value “2” shown in FIG. 6B or FIG. This constitutes an example of the second probability improving means of the present invention that performs improvement control to two high probabilities (medium probability).

According to the control for determining the probability variation set value shown in FIG. 8, the variable display device is controlled to be improved by the second probability improving means during a predetermined period when a predetermined condition predetermined in a game is satisfied. 1 illustrates a configuration.

Further, the configuration of the present invention is exemplified by setting the predetermined period as an initial period from the time when the power is turned on to the time when the specific display result is first derived by the determination step of SC13 shown in FIG.

Further, by changing the set value of the probability variation after the power is turned on as shown in FIG. 17A, the second high probability (the first value of the set value of the probability variation “2”) is changed according to the elapse of the initial period.
The example of the configuration of the second probability improving means that increases the probability in a stepwise manner (medium probability) is illustrated.

In the case where the specific display result is derived up to the predetermined number of times (four times) during the first high probability improvement control period, the processing step of S5 shown in FIG. This constitutes an example of the probability suppressing means of the present invention for suppressing the probability improving control by the first probability improving means.

FIG. 8 illustrates an example of the configuration of the present invention in which the predetermined condition is satisfied when the probability improvement is suppressed by the probability suppressing means in the determination step of SC7 shown in FIG.

When a large hit is made with a certain variable symbol in SA1, "1" is added to the limiter operation determination counter (SA2). On the other hand, if there is no big hit in the variable probability design in SA1, it is determined whether or not a big hit has occurred in the non-variable design (SA3). If a big hit has been made in the non-variable design, the limiter operation determination counter is cleared (SA4). .

The hit value of the random 1 described above is shown in FIG.
As shown in the table of FIG.
The setting is different depending on 3). When the probability fluctuation set value is “1”, “3, 7, 79” of random 1 (0 to 599) is set to the jackpot value, and the jackpot probability becomes a low probability of 1/200 based on this. . When the probability variation set value is “2”, “3, 7, 79, 107” of random 1 (0 to 599) is set to the big hit value, and the big hit probability is 1/150 medium probability based on this. become.
When the probability fluctuation set value is “3”, random 1 (0 to 5)
99), “3, 7, 79, 107, 203, 30”
"7" is set as the big hit value, and based on this, the big hit probability becomes a high probability of 1/100.

The probability variation set value is determined based on the flowchart of FIG. Specifically, in FIG. 8, first, it is determined whether or not a big hit (during a specific game state) (SC1). If it is a big hit in SC1, the probability variation set value is set to "1" and the big hit probability is set to a low probability (SC2). In addition, if it is other than the big hit in SC1, it is determined whether or not the big hit has ended (SC3). If it is not the end of the big hit in SC3, the process proceeds to SC12 described later, while if it is the end of the big hit, it is determined whether or not the big hit has been made with the probable symbol (SC4). S
When a big hit is made with the probability change symbol in C4, the probability change set value is set to "3" and the big hit probability is set to a high probability (S
C5). Also, in SC4, if there is no big hit with the variable probability design, it is determined whether or not a big hit has been made with the non-variable design (S4).
C6). If there is no big hit in the non-probable variable design in SC6, the process proceeds to SC12, whereas if it is a big hit in the non-probable variable design, it is determined whether or not the limiter operation determination flag is set (SC7). If the limiter operation determination flag is not set in SC7, the probability variation set value is set to "1" and the big hit probability is set to a low probability (SC8). When the limiter operation determination flag is set in SC7, the probability variation set value is set to “2”.
And set the jackpot probability to the medium probability (SC9),
Thereafter, the limiter operation determination flag is cleared (SC
At the same time, the medium probability valid period flag is set (S).
C11).

In the above-described SC12, it is determined whether or not the medium probability valid period flag is set. S
When the medium probability valid period flag is not set in C12, it is determined whether or not the probability variation set value is “0” which is an initial value at power-on (SC13), and the probability variation set value is “0”. "", The probability variation set value is set to "2", and the big hit probability is set to the medium probability (SC14).
When the medium probability valid period flag is set in SC12, it is determined whether or not the valid period end flag is set (SC15). When the valid period end flag is set, the probability variation set value is set. Is set to "1" to set the jackpot probability to a low probability (SC16).
The medium probability effective counter is cleared and the medium probability effective period flag is also cleared (SC17). Further, the validity period end flag is cleared (SC18). In the process of updating the medium probability effective counter, as shown in FIG. 7B, first, it is determined whether or not the medium probability effective period flag is set (SB1), and the medium probability effective period flag is set. If so, it is determined whether there is a symbol change (SB2).
If there is no symbol change in SB2, the process directly proceeds to SB4, while if there is a symbol change, “1” is added to the medium probability effective counter (SB3), and then the process proceeds to SB4.
Then, in SB4, it is determined whether or not the count value of the medium probability effective counter has reached "50", and when the count value has reached "50", the valid period end flag is set (SB5).

Next, the setting of the above-mentioned probability fluctuation set value in each game state will be described by taking the game state of the time chart shown in FIG. 9 as an example. In FIG. 9, first, from the time of power-on to the first hit, “2” is set to the probability variation set value as a game privilege for playing a game during that period, and the big hit probability becomes a medium probability. After that, "1" of non-probable variable design
, The probability variation set value is set to "1" at the time of the non-probable variation big hit, and the big hit probability fluctuates to a low probability. Next, when a big hit is made with the probability change symbol “7”, the probability variation set value is changed from “1” to “3” at the end of the probability change big hit.
And the jackpot probability fluctuates to a high probability from this point. Thereafter, when a large hit is made with the non-probable variable symbol "2", the probability variation set value is set to "1" at the time of the non-probable variable big hit, and the big hit probability becomes a low probability. In addition, at the time of the probability change generated at the time of the probability change big hit (at the time of the high probability that the probability change set value is set to “3”), the big hit with the probability change pattern is repeated a predetermined number of times (four times in the embodiment). However, when the limiter is operated in conjunction with this, the non-probable variable big hit symbol (in FIG. 9, the big hit symbol of “1”) is forcibly derived at the next big hit by the limiter operation, and continuously when the probability changes. A big hit with a probable change symbol is suppressed. At the end of the non-probable variable jackpot, “2” is set to the probability variation set value as a game privilege accompanying the limiter operation, and the jackpot probability becomes a medium probability. In addition, the game privilege (medium probability) accompanying the limiter operation is continued until the next big hit or from the end of the non-probable variable big hit set to “2” until the number of times the special symbol is started becomes 50 times. At the end, the probability variation set value is changed from “2” to “1”, and the big hit probability becomes a low probability.

Next, the changing operation of the special symbol will be described with reference to FIG.
And a time chart shown in FIG.
The left, middle, and right special symbols are changed based on the change patterns A, B, and D, respectively. Fluctuation pattern A
Is a fluctuation of acceleration → constant speed → deceleration, fluctuation pattern B is a constant fluctuation of 20 mS per step,
The variation pattern D is a constant variation of 28 mS per step. First, in FIG. 10, when a hit ball wins in the ordinary variable winning ball apparatus 4 and the starting ball detector 7 (described as "starting port winning" in the figure) is turned on to derive a starting signal, the starting signal is derived. At the time of rising, a random number is extracted from random 1 and 3, and stored. Such a random one
The extraction timing of No. 3 is the same even when the start memory is used.
After that, from the derivation of the start signal, a very short time (0.132 seconds)
, The stored value of random 1 is read out to determine whether a hit has occurred, and at the same time, random 2 is extracted. At this time, when the big hit is determined from the value of the random 1, the stored random 3 is read.
Then, after 0.134 to 0.150 seconds from the derivation of the start signal, if the reach becomes due to the extraction of random 1.2, random 6 is extracted.

Thereafter, when 0.190 seconds elapse from the derivation of the start signal, the variation of the left, middle, and right symbols in the variation pattern A is simultaneously started. Then, when 6.300 seconds elapse from the start of the change, the left symbol is set one symbol before the stop symbol, and is varied in the variation pattern B for 0.160 seconds. 6.460 from the start of fluctuation for the right symbol
After the elapse of the second, five symbols before the stop symbol are set, and the symbol is varied in the variation pattern B for 0.800 seconds. In the left and right symbol fluctuations, when the probability fluctuations (medium / high probability), the fluctuation time of the fluctuation pattern A is 2.160 each.
Seconds, 2.320 seconds.

As shown in FIG. 11, when 7.260 seconds elapse from the start of the fluctuation, five symbols before the stop symbol are set for the middle symbol which is the final symbol as shown in FIG. Fluctuate in the variation pattern B for 800 seconds. For the middle symbol in Reach 1, after the variation in variation pattern A, five symbols before the reach symbol are set and varied in variation pattern B for 0.800 seconds. 688-5.152 seconds (12-23
It fluctuates with the fluctuation pattern D. Reach 2
For the middle pattern in, after the fluctuation in the fluctuation pattern A, set 5 patterns before the reaching pattern and set 0.8
Fluctuate with variation pattern B for 00 seconds, and then 5.37
It fluctuates in the fluctuation pattern D for 6 to 7.840 seconds (24 to 35 symbols). In addition, in such a change of the medium symbol, when the probability changes (at the time of medium / high probability), the change pattern A
Is reduced to 3.120 seconds. The selection of the reach 1 and 2 is performed based on the extraction of the random 6 described above.

Next, the operation after the end of the change of the special symbol will be described with reference to FIG. As a result of the change, in the case of a combination of big hit symbols, as shown in FIG.
After 0 seconds, a big hit is determined. Then, after 6.000 seconds from the jackpot determination, the special variable winning opening 17 of the special variable winning ball device 15 is opened for 29.500 seconds, and if there is a V winning (winning to the specific ball detector 20) during that time, a special The opening operation of the special variable winning opening 17 is repeated again 2.000 seconds after the opening of the variable winning opening 17 is completed. In addition, when there is a special symbol start memory at the time when the opening operation of the special variable winning opening 17 is completed (end of the specific game state), FIG.
As shown in the figure, 10.1 from the closing of the special variable winning opening 17
After 90 seconds, the symbol change starts. In this case, at 10.132 seconds after the closing of the special variable winning opening 17, the stored random 1 value is read and determined, and the random 2 is extracted. At this time, when the big hit is determined, the stored random 3 is read. On the other hand, in the case where there is a special symbol starting memory after the result of the change becomes a lost symbol combination, as shown in FIG. 12C, when the change of the middle symbol stops and 1.190 seconds elapse, Left, middle, and right symbol changes are sequentially started. In this case, the value of the stored random 1 is read out and determined, and the random 2 is extracted, 1.132 seconds after the stop of the fluctuation of the middle symbol. At this time, when the big hit is determined, the stored random 3 is read.

Next, the ordinary symbols displayed on the ordinary symbol display 11 will be described. Normal pattern is Fig.13
As shown in (A), 6 of “0.1.1.3.7.9”
The display time of one symbol is 0.128 seconds.
The display is changed at a cycle (0.768 seconds). For these ordinary symbols, as shown in FIG.
Random 4 (3 to 13) for hit determination, which is incremented by 1 every 0.002 seconds, and normal symbol display, which is incremented by 1 every 0.002 seconds and incremented by 1 for the remaining interrupt processing time Random 5 (0 to 5) is provided. As shown in FIG. 14A, each random number of random 5 (0 to 5) is provided corresponding to a normal symbol of "0. 1, 3, 5, 7, 9". In addition, random 4 (3-1
In the extraction of the random number from 3), as shown in FIG. 13 (C), when the value of “3” is extracted and determined to be a hit, the normal symbol display 11 displays “4” of the five random data. The corresponding symbol of "7" is displayed, and the normal variable winning ball device 4 is opened for a predetermined time. On the other hand, if a value other than “3” is extracted at random 4 and it is determined that the value is out of range, random 5 data is extracted, and a lost symbol corresponding to this value is displayed on the ordinary symbol display 11. In addition, when the value extracted by random 5 hits accidentally despite being determined to be out of random 4 and becomes a design, that is, when the random 5 data is “4”, “5” of the random 5 data is used. Is displayed on the ordinary symbol display 11 corresponding to "9".
Also, the determination of the extracted data from the random 4 described above is
This is the case when the hit probability is normal, and when the probability is medium or high, it is determined that the value extracted from the random 4 is any one of “3 to 12”.

Next, the changing operation of the ordinary symbol is shown in FIG.
This will be described with reference to (D) and each time chart in FIG. First, in FIG. 15, when the passing ball detector 10 (in the figure, it is described as passing through a normal symbol gate) is turned on, the random number 4 is extracted and stored at the same time. After that, a predetermined time (0.00
When 2 seconds have elapsed, the stored random 4 is read out and determined, and the random 5 is extracted. And
After 0.004 seconds from the ON of the passing ball detector 10, 27.
Change the symbol for 000 seconds. The fluctuation time of such a normal symbol (27.000 seconds) is at the time of low probability, and at the time of medium / high probability, the fluctuation time of the normal symbol is 5.
000 seconds.

In the case where the passing ball detector 10 has a passing memory after the display result is deviated due to the fluctuation of the ordinary symbol, as shown in FIG. The random number 4 stored after .002 seconds is read out and determined, and the random number 5 is extracted. Then, the fluctuation of the ordinary symbol is started 1.004 seconds after the stop of the ordinary symbol. On the other hand, when the ordinary symbol is hit at the time of low probability, as shown in FIG. 14C, the ordinary variable winning ball device 4 (in FIG.
The normally variable winning opening is opened for 0.500 seconds, and then the stored random 4 is read out and determined and the random 5 is extracted 0.002 seconds after the closing of the normal variable winning ball device 4. And the passing ball detector 10
If there is a passing memory of, the fluctuation of the normal symbol is started again 0.004 seconds after the closing of the normal variable prize ball device 4. In addition, when a normal symbol is hit at the time of medium / high probability, as shown in FIG. 14 (D), the normal variable prize ball device 4 (in FIG. 3.) open for 2.000 seconds, then 4.
After closing for 000 seconds, the normal variable winning ball device 4 is opened again for 2.000 seconds. If the passing ball detector 10 has a passing memory, the stored random 4 is read out and determined 0.002 seconds after the second normal variable winning ball device 4 is closed, and the random 5 is extracted. After performing, the fluctuation of the ordinary symbol is started again 0.002 seconds later.

As described above, the special variable display device 40 according to the present embodiment changes the big hit probability to a high probability in the subsequent game state based on the derivation of the probable variable big hit symbol, and from the power-on time to the first hit. A predetermined number of times (in this embodiment, 4 hits)
When the limiter operates continuously, the change in the big hit probability to the medium probability is given to the player as a game privilege. According to this configuration, the big hit probability is set to three types of low probability, medium probability, and high probability in normal times, so that the game state can be diversified depending on whether the big hit is easy or not. This can lead to an increase in the interest of the game without becoming too disadvantageous for the player. Further, in the configuration in which the probability improvement control to the medium probability is set as the game privilege, there is no need to specially provide a component for providing the game privilege, and the component cost can be reduced accordingly. In other words, the gaming privilege can be provided without limiting the configuration of the ball game machine. For example, in the case where the time reduction of a normal symbol is set as a game privilege, it is necessary to always configure the starting winning opening with a variable winning ball device and to provide a normal symbol display. In addition, according to the configuration of the present embodiment, by setting the probability improvement period to the medium probability from the time of turning on the power to the first hit, it is possible to improve the customer attendance at the time of opening the game hall side, and furthermore, the limiter By controlling the probability increase to the medium probability with the operation, even if the probability change to the high probability is completed by the limiter operation, the subsequent gaming state is easier to hit than usual, so the player loses interest in the game I will not let you.

Next, another embodiment of the present invention will be described as a second embodiment with reference to FIGS. In addition,
In the following description, the same components as those in the above-described embodiment (first embodiment) are denoted by the same reference numerals, and detailed description thereof is omitted. First, the random number used for the change of the special symbol in the second embodiment is as shown in FIG.
As shown in the figure, random 1 (0 to 119)
9), random 2 for displaying all symbols other than the jackpot (0 to 11 for each of the left, middle, and right symbol columns), random 3 for the jackpot symbol arrangement (0 to 11), and reach operation Random 6 (0 to 19). Random 1
3 is a random number that is added and changed by 1 every 0.002 seconds. Random 2.6 is added by 1 every 0.002 seconds and 1 is added to the remaining time of the interrupt processing. Is a random number that fluctuates.

Further, the big hit value of random 1 in the second embodiment is set differently according to the probability fluctuation set values (1 to 5) as shown in the table of FIG. When the probability fluctuation set value is “1”, random 1 (0
To 1,199), “3, 7, 79, 107, 203,
307 "is set as the jackpot value, and the jackpot probability becomes a low probability of 1/200 based on this. When the probability variation set value is “2”, “3, 7, 79, 107, 203, 307, 407” among random 1 (0 to 1199) are set to the jackpot value, and the jackpot probability is determined based on this. 1 /
The first medium probability is 171.4. When the probability fluctuation set value is “3”, “3, 7, 79, 107, 203, 307, 407, 5” among random 1 (0 to 1199)
07 is set as the jackpot value, and the jackpot probability becomes the second medium probability of 1/150 based on this. When the probability variation set value is “4”, “3, 7, 79, 107, 203, 307, 407, 5” among random 1 (0 to 1199)
07, 607 "is set as the jackpot value, and the jackpot probability becomes a third medium probability of 1 / 133.3 based on this. When the probability variation set value is “5”, random 1 (0 to 119)
9), “3, 7, 79, 107, 203, 307,
407, 507, 607, 707, 807, 907 "are set to the jackpot value, based on which the jackpot probability is 1 /.
A high probability of 100. That is, the jackpot probability of the second embodiment is a low probability, a first medium probability, a second medium probability, a third medium probability,
Five types are set that increase in the order of high probability.

Next, the setting of the above-mentioned probability fluctuation set value in each game state will be described by taking the game state of the time chart shown in FIG. 17B as an example. In FIG. 17B, first, at the time of power-on, “2” is set to the probability variation set value as a game privilege for playing a game at the time of power-on, and the big hit probability becomes the first medium probability. Then, when the number of times of change of the special variable display device 40 (number of times of starting the special symbol) reaches 100 from the time of power-on, the probability change set value is changed from “2” to “3” at that time, and the big hit probability becomes 2 The probability is improved. Similarly, set “3” to the probability fluctuation set value.
When the number of times the special symbol is started becomes 100 times from the time when is set (the number of times the special symbol is started is 200
At that time, the probability variation set value is changed from “3” to “4” at that time, and the big hit probability is improved to the third medium probability. Note that the third medium probability is continued until the next big hit. Thereafter, when a large hit is made with the non-probable variable symbol "1", the probability change set value is set to "1" at the time of the non-probable variable big hit, and the large hit probability fluctuates to a low probability. Next, when a big hit is made with the probability change symbol “7”, the probability variation set value is changed from “1” to “5” at the end of the probability change big hit, and the big hit probability changes to a high probability from this time.

In addition, at the time of the probability change occurring at the time of the probability change big hit (at the time of the high probability in which the probability change set value is set to “5”), the big hit with the probability change symbol is repeated for a predetermined number of times. When the limiter is operated, the limiter operation forcibly derives a non-probable variable jackpot symbol ("1" big hit symbol in FIG. 17A) at the time of the next big hit, and the probability variable symbol is continuously displayed when the probability changes. A big hit is suppressed. At the end of the non-probable variable jackpot, “4” is set to the probability variation set value as a game privilege accompanying the limiter operation, and the jackpot probability becomes the third medium probability. And
When the number of start of the special symbol becomes 20 from the point when the probability variation set value is set to “4” with the limiter operation,
At that time, the probability variation set value is changed from “4” to “3”, and the big hit probability falls to the second medium probability. Similarly,
When the number of times the special symbol is started becomes 20 times from the time when the probability variation set value is set to “3” (the number of times the special symbol is started from the time when the probability variation set value is set to “4” due to the limiter operation) At that time, the probability variation set value was changed from “3” to “2” at that time, the jackpot probability decreased to the first medium probability, and “2” was set to the probability variation set value. When the number of times of starting the special symbol becomes 10 times from the time point (when the number of times of starting the special symbol becomes 50 from the time point when the probability fluctuation set value is set to “4” due to the limiter operation), the probability fluctuation setting is made at that time. The value is changed from “2” to “1”, and the big hit probability decreases to a low probability.

As described above, according to the configuration of the second embodiment, a predetermined period elapses for the probability improvement control to the medium probability of giving as a game privilege (in the second embodiment, the number of times of starting a special symbol). (In the second embodiment, 3
Since the probability fluctuates in (stage), the gaming state can be further diversified depending on whether or not a big hit is easy. As a specific configuration, the medium probability (first medium probability) is gradually increased and controlled with the elapse of a period after the power is turned on, so that even a player who does not easily hit a large hit easily hits the hit.
By allowing the player to continuously play the game after the power is turned on, and by gradually lowering the medium probability (third medium probability) with the elapse of the period after the limiter operation, the probability of the game after the limiter operation is increased. The monotony of the game content can be eliminated. In the second embodiment, the control that gradually increases the medium probability and the control that gradually decreases the medium probability are shown.
However, the present invention is not limited to this, and a combination of the probability improvement and the probability reduction may be performed in accordance with the passage of time.

In the first and second embodiments described above,
The present invention is not limited thereto, and various modifications can be made within the scope of the present invention. For example, in the embodiment, the probability change caused by the probability change big hit is set to the next big hit, but not limited to this, the probability change caused by the probability change big hit is repeatedly generated a predetermined number of times at the end of the big hit It may be. In addition, the ratio of the probability-change big hit symbol to the big hit symbol, in other words, the probability that the probability variation occurs on the assumption of the big hit is set to ２, but the ratio (probability) is not limited to this. Further, the predetermined condition for changing the probability to a high probability is not necessarily limited to a jackpot with a probable change symbol. In other words, besides the random number (random 3) for determining the special symbol (big hit symbol), the presence / absence of the probability change is also determined at the same time, and the random number for the probability change determination is provided separately from the random number for the big hit symbol determination. Whether or not there is a certainty change may be determined separately from the extraction of the random numbers irrespective of the big hit symbol. Further, the determination result may be displayed after the end of the big hit or the like.
Also, the predetermined condition for controlling the probability improvement to the medium probability as a game privilege is that the game is performed within a period from the time of turning on the power to the initial hit, or that the limiter is operated a predetermined number of times during the probable change. Not limited. For example, two types of probable variable symbols are set, one for determining a high probability (for example, “7”) and one for determining a medium probability (for example, “3”).
In the case of a big hit in “7.7”, a high probability is given as a game privilege in addition to the occurrence of a specific game state, while “3.3.
In the case of a big hit in "3", a medium probability may be given as a game privilege in addition to the occurrence of the specific game state. In addition, the medium probability may be changed or lottery may be performed for each symbol change (start winning), and if it is a hit, the medium probability may be obtained, and the medium probability may be changed until the next big hit (or up to 50 times of starting). .

Further, as the configuration for performing the medium probability variation, the time reduction control may be performed together with the medium probability variation as in the embodiment, or the time reduction control may be performed only when the probability is high, and At the time, only the fluctuation control to the medium probability may be performed (the time reduction control is not performed). In the embodiment, the starting winning opening is constituted by the ordinary variable winning ball device 4 and the ordinary symbol display 11 is provided. However, a specification without these (a specification having only a medium probability) may be used. Also, the medium probability is desirably a middle probability between the low probability and the high probability in normal times. This is because the effect is diminished if the medium probability is too low, and there is no difference from the high probability if the medium probability is too high.

In the embodiment, the special variable display device for changing the special symbol is constituted by a rotating drum.
The present invention is not particularly limited to this, and may be CRT, LCD, L
An image display such as ED, VFD, EL, or plasma, or a leaf type or a belt type may be used. In addition, as a configuration of the ball-and-ball game machine, the change of the identification information on the variable display device is started in accordance with the detection of the winning ball of the starting ball detector, and when the identification information has a predetermined display result, a specific game state occurs. A ball game machine (commonly referred to as a first type) that opens a variable winning ball device is illustrated as an example, but is not particularly limited to this, and is associated with detection of a winning ball by a starting ball detector. To start changing the identification information on the variable display device,
When the identification information has a predetermined display result, a right generation state is established. In this state, when a ball is hit in a specific area, a specific gaming state is generated, even if the game machine is a ball game machine (generally referred to as a third type). Good.

[0055]

As is apparent from the above description, according to the first aspect of the present invention, when the display result derived to the variable display section of the variable display device becomes a predetermined specific display result. In a ball game machine capable of generating a specific game state advantageous to a player, first probability improving means for controlling the probability of deriving the specific display result to be a first high probability higher than normal, and the specific display Probability improvement determining means for determining whether to improve to the first high probability based on derivation of a result, and a probability of deriving the specific display result being higher than normal and lower than the first high probability A second probability improving means for controlling to increase to a second high probability, during a predetermined period of time when a predetermined condition predetermined in the game is satisfied,
The improvement of the variable display device is controlled by the second probability improving means. With this configuration,
Since three types of probabilities for deriving the specific display result are set, that is, a normal low probability and first and second high probabilities, the game state can be diversified depending on whether it is easy to hit a big hit or not. The entertainment of the game can be improved without becoming too disadvantageous for the game hall. Further, in the configuration in which the probability improvement control to the second high probability is set as the game privilege, it is not always necessary to provide a special component such as a normal symbol display for providing the game privilege, and the component cost can be reduced accordingly. . In other words, it is possible to provide a configuration in which a game privilege is provided even to a ball game machine that does not have a special component for a game privilege (for example, a normal symbol display device), and thus the ball game machine. It is possible to give a game privilege without limiting the configuration.

According to a second aspect of the present invention, the second probability improving means varies the probability in a plurality of stages according to the elapse of a predetermined period during the predetermined period. With this configuration, the probability of deriving the specific display result can be set to four or more types, and the gaming state can be further diversified depending on whether or not a big hit is easy.

According to a third aspect of the present invention, the predetermined period is an initial period from when the power is turned on to when the specific display result is first derived.
With this configuration, by setting the period from the time of turning on the power supply to the first hit as the probability improvement period to the second high probability, it is possible to improve the customer service at the time of opening the game hall side.

According to a fourth aspect of the present invention, the second probability improving means changes the second high probability stepwise according to the elapse of the initial period. With this configuration, the second high probability of becoming a game privilege increases stepwise with the elapse of a predetermined period (for example, the number of starts) after power-on, so that there are some players who do not easily hit the jackpot. Is also easy to hit, and the player can continuously play the game after the power is turned on.

According to a fifth aspect of the present invention, when the specific display result is continuously derived up to a predetermined number of times during the improvement control period based on the first high probability, the first probability improving means is provided. There is provided a probability suppressing means for suppressing the probability improvement control from being performed, and the predetermined condition is satisfied when the probability improvement is suppressed by the probability suppressing means. With this configuration, even if the probable change control (probability improvement control by the first probability improvement means) is completed by the limiter operation, the subsequent game state is easier to hit than in the normal case, so that the player is interested in the game. Will not be lost.

Further, in claim 6 of the present invention, the second probability improving means includes a step-by-step method for generating the second high probability stepwise according to a lapse of time after the probability improvement is suppressed by the probability suppressing means. It is characterized by fluctuating. With this configuration, after the limiter is activated, the second high probability of becoming a game privilege gradually decreases with the elapse of a predetermined period (for example, the number of times of starting), so that the game content after the limiter is activated is reduced. Monotony can be eliminated.
