Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game having a variable display device capable of generating a specific game state advantageous to a player when a display result of a variable display section becomes a predetermined specific display result. It is about the machine.

2. Description of the Related Art Conventionally, a variable display device generally provided in a pachinko game machine as a ball-and-ball game machine variably displays symbols on a plurality of rows of variable display portions, and the display result of each variable display portion is predetermined. When a big hit symbol (specific display result) is reached, a specific game state is generated. In addition, such a variable display device is proposed in which one of the plurality of reach variation modes is selected and executed when the reach is reached by the symbol variation, and a big hit is made for each reach variation mode. By setting different expectation levels, the interest in the change in reach could be stimulated. In addition, as a mode of reach variation, generally, a mode in which each variable display section is sequentially stopped and displayed is a reach variation mode with low jackpot expectation (this is commonly called normal reach), and the display of each variable display section is changed. The method of deriving the results all at once was defined as a reach variation mode with a high expectation for a big hit (this is commonly called super reach). In addition, the variable display device,
A special game state is generated by changing the hit probability of the hit judgment in addition to the occurrence of the specific game state when it becomes a predetermined probability variation pattern among the big hit symbols to be displayed (hereinafter, also referred to as probability variation). There has also been proposed, and in such a variable display device, if a big hit is again made with a probability variation pattern during the special game state, the duration of the special game state is extended and controlled.

[0003]

However, in the variable display device capable of extending the continuation period of the special game state as in the above-mentioned conventional case, the reach variation mode similar to the normal time other than the normal state is provided during the special game state. The selection was controlled. That is, even during the special game state, the appearance rate was higher in the normal reach with a lower jackpot expectation than in the super reach with a jackpot expectation. As a concrete phenomenon, in the special game state in which the expectation for the probability change hit is higher than the expectation for the big hit, the normal reach that sequentially derives the display result of each variable display portion has appeared. Therefore, during the reach change before the final stop design is stopped and displayed, it is already known whether or not there is a probability change hit, in other words, whether or not the duration of the special game state is extended, and there is a problem that the interest of the game is halved. Was. The present invention has been made in view of the above problems, and its object is to determine whether or not to extend the duration of the special game state by deriving or after deriving a specific display result on the variable display unit. It is to provide a ball game machine that can improve the interest of the game.

Next, the changing operation of the special symbol by the special variable display device 40 will be described with reference to the time charts and explanatory diagrams shown in FIGS. 6 to 10. First, the random number used for the varying operation of the special variable display device 40 will be described. In the special variable display device 40, as shown in FIG.
Four types of random numbers as shown in (A) are used, and these random numbers are random 1 for big hit determination.
(0-292), random 2 for displaying all symbols other than jackpot (0-20 for each of the left, middle, and right symbol columns), and random 3 for jackpot symbol arrangement (0-44), Random 6 (0 to 19) for reach operation.
The random numbers 1 and 3 are random numbers which are added and changed by one every 0.002 seconds, and
6 is a random number that varies by being incremented by 1 every 0.002 seconds and incremented by 1 in the remaining time of interrupt processing. Then, as shown in FIG. 6 (B), when the value extracted from the random 1 is “3”, it is determined as a big hit, and the big hit symbol and arrangement are determined by the random 3 to determine each special variable display device 40. It is displayed on the symbol display portions 43 to 45. On the other hand, the value extracted from random 1 is “3”
In other cases, it is determined to be off and the symbol based on the extracted value in random 2 is displayed as an off symbol on each of the special symbol display portions 43 to 45 of the special variable display device 40. Also, when the value extracted by random 2 coincides with the big hit symbol by chance, 1 is added to the random 2 data for the middle symbol row, and it is displayed as a missing symbol. In addition, at the time of probability fluctuation (at the time of high probability), "3 / 77.9 / 1" in Random 1
The value of "03.107" is a random number for determining the big hit. In addition, by extracting Random 3, “JA
When the big hit of the probability variation pattern in "C" or "F" is determined, a number limit value is provided so that the number of repetitions of the probability variation control, which will be described in detail later, does not exceed 2. That is, "JA
In the probability variation big hit in "C" or "F", if the probability variation number exceeds 2 by the judgment of the number of times limit value, "5" is added to the value of Random 3 to force other than the probability variation symbol. The big hit symbol is displayed on each of the special symbol display portions 43 to 45.

Further, the specific fluctuation of the special symbol is as shown in the time charts of FIGS. In addition,
The fluctuation of each of the left, middle, and right symbol rows is performed based on the pattern shown in FIG. Change pattern A is acceleration →
It is a change from constant speed to deceleration, and the change pattern B is 1
It is a constant fluctuation of 20 mS per step, and the fluctuation pattern C is 20 mS → 24 mS → 26 mS per step.
Then, the speed gradually decelerates and finally becomes a constant speed of 28 mS. The fluctuation pattern D is 28 m per step.
It is a constant variation of S. First, in FIG. 7, when a hit ball is won in the normal variable winning ball device 4 and a starting ball detector 7 (in FIG. 7, described as a starting mouth winning) is turned on to derive a starting signal, the starting signal Random 1 or 3 at start-up
Random numbers are extracted from and stored in them. afterwards,
When a minute time (0.132 seconds) has elapsed from the derivation of the starting signal, the stored value of random 1 is read to determine whether or not there is a hit, and at the same time, the value of random 2 is extracted.
At this time, when the hit is determined from the value of random 1, the stored random 3 is read. Also,
In the case of reaching due to the extraction of Random 1.2, the value of Random 6 is extracted 0.134 to 0.150 seconds after the start signal is derived. After that, when 0.190 seconds have elapsed from the derivation of the starting signal, the variation of the left symbol column is started in the variation pattern A, and 0.19 is derived from the derivation of the starting signal.
When 2 seconds have passed, the fluctuation of the middle symbol sequence is started in the fluctuation pattern A (see FIG. 8), and 0.
When 194 seconds elapse, the fluctuation of the right symbol row is started in the fluctuation pattern A. Then, for the left symbol row, when 6.300 seconds have elapsed from the start of variation, one symbol before the stop symbol is set and varied in the variation pattern B for 0.160 seconds, and then the symbols are stopped and displayed. . For the right symbol column, when 6.460 seconds have elapsed from the start of variation, 5 symbols before the stop symbol are set and varied in the variation pattern B for 0.800 seconds, and then the symbols are stopped and displayed. Further, for the middle symbol row, as shown in FIG. 8, in the case other than the reach, when 7.260 seconds have elapsed from the start of variation, 5 symbols before the stop symbol are set and the variation pattern is 0.800 seconds. After changing in B, the symbols are stopped and displayed. In addition, in such fluctuation of each left, middle, right symbol row,
When the probability changes (high probability), the change time in the change pattern A is 2.160 seconds, 3.120 seconds, and 2.320 seconds, respectively.
Reduced to seconds.

Next, the reach fluctuation will be described. In addition, the type of reach variation is the reach variation (reach 1) of only the middle symbol row after the reach symbol is constituted by the left and right stop symbols described above, and the left, middle and right symbol rows at the same time. Reach fluctuation (reach 2/3/3) to stop and display
And, roughly divided into. First, the reach variation (reach 1) of only the middle symbol row after the reach symbol is constituted by the left and right stop symbols will be described. In FIG. 8, for the middle symbol row in the reach 1, after the variation in the variation pattern A, a big hit symbol is set on the reach line (at the time of W reach, the one with the larger symbol position is set).
It is changed by the change pattern B for 2 seconds, and then 0.436
It is changed in the change pattern C for about 9.620 seconds and the symbol is stopped and displayed.

Next, the reach variation (reach 2, 3, 3) for simultaneously stopping and displaying each of the left, middle, and right symbol strings will be described. In addition, these reach 2, 3 and 3 are special reach variation modes of the present invention in which it is possible to recognize for the first time whether or not the probability variation symbol (special display result) is obtained at the time of deriving the display result to the special symbol display portions 43 to 45. I am doing it. In addition, the reach 3 is a developed version of the reach 3 because the reach 3 changes to a specific display mode during the change. In the variation of reach 2 in FIG. 9, when each symbol is varied by variation pattern A for 6.460 seconds, “7,7,7” is set in the center line, and 3.348 to
It is changed in the change pattern C for 7.828 seconds and all symbols are stopped and displayed all at once. However, when the display result is lost, only the middle symbol is finally shifted by one symbol. Further, the variation pattern C of the reach 2 is a variation speed at which it is possible to visually recognize that all the symbols are aligned in the big hit symbol. On the other hand, in the variation of the reach 3, all the symbols are stopped and displayed at the same time after changing each symbol in the variation pattern A for 25.000 seconds. In this way, the reach 3 has a long variation pattern A at the start of the symbol variation, and it is not possible to visually confirm whether or not the symbols are aligned at the time of the variation. Further, in the variation of reach 3 which is an evolved type of reach 3, after the variation pattern A (reach 3) is completed, 0.
It is temporarily stopped for 480 seconds, and then is changed in the change pattern D for 0.224 to 4.480 seconds to stop and display the symbol.

Further, the selection of the above-mentioned various reaches 1 to 3 is performed based on the distribution table diagram of the random 6 shown in FIGS. Specifically, FIG.
In (B), when the display result at normal time is lost, reach 1 has a random 6 extracted value of “0 to 14”.
Reach 2 is selected when any of (15 random numbers) is selected, and reach 2 is selected when any of the extracted values of random 6 is “15 to 18” (4 random numbers), and reach 3 of random 6 is selected. It is selected when the extracted value is “19” (one random number), and reach 3 is not selected. Thereby, the selection rate of the reach variation mode (reach 1) other than the special reach variation mode in the normal time loss, in other words, the appearance rate (= (the number of random numbers when the reach 1 is lost) / the total number of random numbers of the loss) ) × 100) is 75%, while the appearance rate of the special reach variation mode (reach 2 ・ 3 ・ 3) at normal time loss (= (number of random numbers at loss in each reach 2 ・ 3 ・ 3 / total) The number of random numbers lost in () × 100) is 25%
Becomes Further, when the display result in the normal time is a big hit, the reach 1 is selected when the extracted value of the random 6 is any of “0 to 3” (4 random numbers), and the reach 2 is the extraction of the random 6. The value is selected when the value is "4 to 10" (7 random numbers), and the reach 3 is selected when the extracted value of random 6 is "11 to 14" (4 random numbers). , Reach 3 has a random 6 extracted value of “15 to 1”.
9 ”(5 random numbers). By this, the appearance rate of the reach variation mode (reach 1) other than the special reach variation mode in the normal time (= (the number of random numbers at the time of the big hit of reach 1 / the number of the random numbers at the total)
X100) is 20%, while the appearance rate of the special reach variation mode (reach 2/3/3) per normal time (=
(Number of random numbers at the time of big hit of each reach 2.3, 3 / total number of random numbers at the big hit) x 100) is 80%.

Further, in FIG. 10C, when the display result at the time of high probability is lost, the reach variation occurs when the extracted value of random 6 is "0 to 6" (7 random numbers). Reach 1 is selected when any of the extracted values of Random 6 is “7.8” (two random numbers), and the reach is selected. 2 has a random 6 extracted value of “9 to 15” (7
Random number), the reach 3 is selected when the extracted value of the random 6 is “16 to 19” (4 random numbers), and the reach 3 is not selected. As a result, the appearance rate of the reach variation mode (without reach / reach 1) other than the special reach variation mode with high probability loss (= (number of random numbers at the time of loss without reach and reach 1 / total random number of loss) Number of) x 100) is 4
While it is 5%, the appearance rate of the special reach variation mode (reach 2 ・ 3 ・ 3) with high probability loss (= (each reach 2
-The number of random numbers at the time of loss of 3/3 / the total number of random numbers at the time of loss) x 100) is 55%. When the display result at the time of high probability is a big hit, no reach variation is not selected, reach 1 is selected when the extracted value of random 6 is “0” (one random number), and reach 2 is selected. Random 6 is selected when any of the extracted values of “1 to 9” (9 random numbers) is selected, and reach 3 is selected when the extracted value of random 6 is any of “10 to 14” (5 random numbers). When the reach 3 is selected, the extracted value of the random 6 is “15 to 1”.
9 ”(5 random numbers). Thereby, the appearance rate of the reach variation mode (without reach / reach 1) other than the special reach variation mode with high probability per hour (= (number of random numbers at the time of jackpot without reach / reach 1 /
The total number of random numbers per jackpot) x 100) is 5%, while the appearance rate of the special reach variation mode (reach 2/3/3) per high probability time (= (each reach 2/3/3)
The number of random numbers at the time of jackpot / total number of random numbers at jackpot) × 100) is 95%.

As described above, in the special variable display device 40 of this embodiment, the special reach variation mode at the time of high probability (during the special game state) in both cases where the display result is lost and when it is a big hit (Reach 2/3/3
) Appearance rate is set higher than that of normal times. That is, in the case of reach in the variation of the special symbol which can be the determination of the probability variation during the probability variation (extension determination of the duration of the special game state), is it the probability variation symbol (special display result) when the display result is derived? By making many special reach variation modes that can be recognized for the first time appear, it is possible to improve the expectation for the probability change hit during the probability change (special game state), and as a result, the interest of the game is improved.

Next, the operation of the special variable display device 40 after the end of variation will be described with reference to FIGS. First, as a result of the variation, when a combination of big hit symbols is obtained, as shown in FIG. 11 (A), a big hit determination is made 1.500 seconds after the variation stop of the middle symbols. 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,
When 2.000 seconds have elapsed since the opening of the special variable winning opening 17, the opening operation of the special variable winning opening 17 is repeated again. After that, when there is a starting memory of the special symbol at the time of ending the opening operation of the special variable winning opening 17, FIG.
As shown in (B), 1 from the closing of the special variable winning opening 17
After 0.190 seconds, the symbol change starts. In this case, the stored random 1 value is read out and determined, and the random 2 is extracted 10.32 seconds after the closing of the special variable winning opening 17. 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 start-up memory of the special symbol after the result of the change is the combination of the symbols that are out of alignment, FIG.
As shown in (C), the fluctuation of the middle symbol stopped and 1.19.
When 0 seconds have elapsed, the fluctuation of each of the left, middle, and right symbol rows is sequentially started. Note that, in this case, the stored random 1 value is read out and determined, and the random 2 is extracted, after 1.132 seconds from 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 normal symbols displayed on the normal symbol display 11 will be described. Ordinary design, Figure 12
As shown in (A), 6 of “0.1.1.3.7.9”
It is a type, and the display time for one symbol is 0.128 seconds.
The display is changed at a cycle (0.768 seconds). Also, 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 And random 5 (0 to 5).
Each random number of random 5 (0 to 5) is shown in FIG.
As shown in the figure, the symbols are provided corresponding to the respective ordinary symbols of "0, 1, 3, 5, 7, 9". Also, random 4 (3 ~
FIG. 12 (C) in extracting the random number from 13).
As shown in the figure, when the value of “3” is extracted and it is determined that a hit has occurred, the normal symbol display 11 displays “4” of five random data.
Is displayed, and the normal variable winning ball device 4 is opened for a predetermined time. On the other hand, random "4"
If values other than are extracted and judged to be out of order, random 5
The data is extracted, and the out-of-design corresponding to this value is displayed on the ordinary symbol display 11. In addition, when the value extracted at random 5 happens to be a symbol even though it is determined to be out of order at random 4, that is, the random 5 data is “4”.
In the case of, an out-of-order symbol of “9” corresponding to “5” of the five random data is displayed on the ordinary symbol display device 11. The determination of the data extracted from the random 4 is a case where the hit probability is normal, and when the probability is high, the value extracted from the random 4 is determined to be a hit by any one of “3 to 12”. On the other hand, other values of “13” are determined to be out of order.

Next, the variation operation of the normal symbol on the above-mentioned normal symbol display 11 is shown in FIGS. 13 (B) to 13 (D) and FIG.
A description will be given based on each time chart in (C). First,
In FIG. 14 (C), when the passing ball detector 10 (in the figure, it is described as passing through the normal symbol gate) is turned on, the random 4 is extracted and stored at the same time. afterwards,
Predetermined time (0.002 seconds) from ON of passing ball detector 10
, The stored random 4 is read and determined, and the random 5 is extracted. Then, 0.004 seconds after the passing ball detector 10 is turned on, 27.008
The symbol usually fluctuates for seconds. In addition, such a variation time of the normal symbol (27.008 seconds) is a low probability time, at the time of high probability, the variation time of the normal symbol is shortened to 5.120 seconds.

Further, when there is a passing memory of the passing ball detector 10 after the normal symbol is disengaged in the above-described fluctuation, as shown in FIG. 13B, 1.002 seconds from the stop of the normal symbol. The random 4 stored later is read and determined, and the random 5 is extracted. Then, 1.004 seconds after the stop of the normal symbol, the fluctuation of the normal symbol is started. On the other hand, when the normal symbol is a win at a low probability, as shown in FIG. 13 (C), the ordinary variable winning ball device 4 (in the same figure, the ordinary variable winning port and (Described) is opened for 0.500 seconds, and then 0.002 seconds after the normal variable winning ball device 4 is closed, the stored random 4 is read and judged, and the random 5 is stored.
Is extracted. If the passing ball detector 10 has a passing memory, the normal variable winning ball device 4 is closed 0.0
After 04 seconds, the fluctuation of the ordinary symbol starts again. In addition, in the case of a high probability of winning a normal symbol,
As shown in (D), the normal variable winning prize ball device 4 (described as a normal variable winning opening in the figure) was opened for 2.000 seconds and then closed for 4.000 seconds at the same time as the stop of the normal symbol. Thereafter, the normal variable winning ball device 4 is opened again for 2.000 seconds. If there is a passage memory of the passing ball detector 10, 0.0 is counted from the closing of the second ordinary variable winning prize ball device 4 for the second time.
After 02 seconds, the stored random 4 is read and determined, and the random 5 is extracted.
Two seconds later, the normal symbol starts to change again.

Next, the operation in which the winning probability of the special symbol and the normal symbol changes in probability will be described with reference to FIGS. 14 (A) and 14 (B). In each of FIGS. 14A and 14B, "7" and "7" are displayed in each of the special symbol display portions 43 to 45 of the special variable display device 40 (described as a condition device in FIGS. 14A and 14B). V "" J
When a big hit symbol, that is, a probability variation symbol, which is prepared by either AC or F, is derived, the probability variation control is executed based on this. The specific control of the probability variation is to change the probability to a high probability upon the end of the specific game state (operation of the condition device) by the probable change symbol, and then, when the next specific game state occurs, Return the hit probability to the normal probability. The end probability and the occurrence of the specific game state as described above (not particularly limited to the end time and the occurrence time, but related to the occurrence or the end of the specific game state) repeat the fluctuation of the hit probability again to obtain the total. Two times of probabilistic control are performed. Moreover, when such a probability variation control accompanies the probability variation pattern of "7,7,7" or "VVVV" shown in FIG. 14 (A), when a big hit is again made with the probability variation pattern during that probability variation, 2 after the big hit
The probability change control of the number of times is performed. On the other hand, when the probability variation control accompanies the probability variation pattern of “JAC / JAC / JAC” or “F / F / F” shown in FIG. 14B, the probability variation is again determined during the probability variation based on the number-of-times limit value described above. The control is performed so as not to make a big hit with the design. That is, "7"
Or, if a big hit with the probability variation pattern of "V", the probability change is updated twice, and if a big hit with the probability variation pattern of "JAC" or "F", the probability change ends twice. The probability variation control associated with the derivation of the probability variation pattern is not limited to this. For example, when a big hit with a probability variation pattern of "7" or "V" is a three-time probability variation, while a big hit with a probability variation pattern of "JAC" or "F" may be a one-time probability variation, and a probability variation pattern again. In case of a big hit with, you may add instead of updating. Further, instead of setting a plurality of probability variation patterns, it is possible to make a probability change twice with any probability variation pattern, and if the probability variation pattern hits again, the number of probability variation is updated, or one probability variation may be added. .

As described above, in the present embodiment, during the special game state, it is possible to recognize for the first time whether or not the special display result (probability change hit) will be obtained at the time of deriving the display result as compared with the normal time. Since the rate is set high, most or all of the determinations of extension of the duration of the special game state are made at the same time when the specific display result is derived, and as a result, the interest of the game is improved. In the present embodiment, the reach operation is partially omitted at a high probability (no reach operation is selected according to the extraction of the random 6) so that the next big hit is generated quickly, but the present invention is not limited to this. The reach may be changed without fail during the reach.
In addition, in the special game state, in order to set the appearance rate of the special reach variation mode higher than in the normal time, it is set to 55% in the case of high probability loss, while it is set to 95% in the case of high probability hour. The appearance rate of the special reach variation mode is not limited to these numerical values. For example, at a high probability (during a special game state), the appearance rate of the special reach variation mode may be 100% regardless of whether or not the player has missed, or the reach variation may be all except the special reach variation mode. In addition, the occurrence rate of the special reach variation mode is high only when the probability of loss is higher than that of the normal time, or the appearance rate of the special reach variation mode is high only when the jackpot is large. The appearance rate of the special reach variation mode may be higher in the high probability case than in the normal case in combination of both. In addition,
The special reach variation mode is not limited to that of the present embodiment, but may vary in synchronization with only the left and right symbols, or may vary again due to a temporary stop state (for example, the symbol is swinging up and down). In other words, it may be a reach variation mode in which it is not known which symbol will be a big hit (whether to be the special display result) before the derivation of the display result (decision of the symbol).

The above-described embodiment (first embodiment)
Then, the extension control of the continuation period of the special game state (probability variation control) is determined by the probability variation hit during the probability variation, but the invention is not limited to this. For example, only when the probability is high, the probability variation extension control may be determined by the probability variation determination symbol. Hereinafter, such a configuration will be described as a second embodiment. In the second embodiment, a display device (not shown) for probability variation determination is provided in addition to the various constituent members described in the first embodiment. When the big hit symbol is derived during the special game state, the determination display device starts variation of the probability variation determination symbol in response thereto and derives the determination display result. The probability variation determination symbol is composed of a hit symbol (probability variation symbol) "F" and a deviating symbol "-", and the display result is determined according to an extracted value of a random number (not shown). There is. Next, the processing process of the probability variation determination control associated with the operation of the determination display device will be described with reference to the flowchart of FIG.

In FIG. 15, first, it is determined whether or not the display result of the special symbol is the specific display result (big hit symbol) (S1). When it is determined that the specific display result is obtained in S1, it is then determined whether or not it is in the high probability state, that is, whether or not in the special game state in which the probability variation control is performed (S2). When it is determined in S2 that it is a normal time other than the special game state, it is determined whether or not the specific display result in S1 is a special display result (probability variation pattern) (S3). When the special display result is not obtained in S3, the probability is not changed (S4), and the process returns to the main flow. When the special display result is obtained, the probability is changed after the end of the specific game state (S5). In addition, when it is determined that the special game state is in S2, whether or not the probability variation determination symbol derived to the determination display device is the probability variation symbol (“F”), that is, the determination display result is missed. Is determined (S6). When the probability variation determination symbol becomes "-" other than the probability variation symbol in S6 and the determination display result deviates, the above S4.
Probability change does not occur by shifting to, that is, it returns to the main flow without extending control of the duration of the probability variation control (special game state). On the other hand, when the probability variation determination symbol becomes "F" of the probability variation symbol in S6 and the determination display result hits, the probability variation is performed by shifting to S5, that is, the probability variation control (special game state) currently being performed is continued. Control extension of period.

As described above, in the second embodiment, the occurrence of the normal special game state (probability variation control) is determined by the type of big hit symbol (the special symbol is the probability variation symbol), while the special game state (probability variation control). Occurrence of a special game state, that is, the extension control of the duration of the probability variation control is determined by the probability variation determination symbol. Further, this probability variation determination symbol is designed to derive a determination display result by starting the variation on condition that the jackpot symbol is derived. For this reason, the special game state (probability change control) continuation period extension determination is made after the derivation of the specific display result (big hit symbol), and as a result, similar to the effect of the first embodiment, the interest of the game is improved. It is like this. In the second embodiment, a separate display device is provided for the probability change determination, and the determination display result is derived after the specific display result is derived, but the present invention is not limited to this. The derivation time of the determination display result may be from the derivation time of the specific display result to after the derivation, and the decorative pattern display 47, the special display device 40, or various decorative lamps are also used as the display device for the probability variation determination. You may.

It is also possible to use a display device such as D, EL, or plasma, or a roof type or belt type. Further, in the present embodiment, the variable display device has a symbol row composed of a hit symbol and an out symbol and is displayed on five hit lines, but the invention is not limited to this. For example, all symbol rows are permuted. It may be configured to have a hit pattern and display it on one hit line. 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.

Further, the entire ball game machine is constituted by a display device such as an LCD display, that is, the components such as "hitting ball" and "variable winning ball device" are displayed on the display device in a simulated manner. Can also be configured. In this case, the payout of the prize ball may be performed on behalf of a point or the like.

Further, in the present embodiment, the special game state is the probability variation control of the special symbol and the normal symbol, but is not limited to this, if the game control that is advantageous to the player is the special game state. Good. For example, time reduction control or probability variation control for special symbols or ordinary symbols, extension control of the opening period of electric hands (for example, ordinary variable winning ball device), starting passage area for special symbols or ordinary symbols Expansion control (for example, control to change the normal winning opening as the starting winning opening of the special symbol), increase control for the number of prize balls (for example,
Control for increasing the number of prize balls accompanying the winning from normal 13 to 15) or control for improving the passing rate to a predetermined area (for example, providing a ball regulating device upstream of the starting winning opening to control the ball) The control for improving the start winning rate by the operation of the device) can be set to a special game state. Further, when the present invention is applied to the third type, the control for improving the winning rate to a specific area is performed in the special game state. It may be. It goes without saying that a special game state can be set by combining the above game controls.
