2. Description of the Related Art In such a type of ball-and-ball game machine, for example, a display result of a variable display device whose display state can be changed is specified in a predetermined display mode (for example, Japanese Patent Application Laid-Open No. H11-157572). For example, when the first control condition such as 111, 333, 777, etc. is satisfied,
For example, there has been a system in which a variable winning prize ball device is opened and controlled to a first state which is advantageous to the player, and is controlled to be a first gaming state which is particularly advantageous to the player such as a big hit. Then, since the first game state is a state particularly advantageous to the player, if the probability of the first control condition for generating the first game state is too high, the game hall will be operated in the red. Therefore, the probability of establishment of the first control condition is usually set relatively low.

[0003]

As described above, in the conventional ball game machine, the probability that the first control condition is satisfied is not so high, so that the first control condition is satisfied once. Then, if the first game state occurs, the player predicts that the first control condition will not be satisfied for a while thereafter, and the game becomes an uninteresting game thereafter, so the game is stopped and returned. There were many players.

[0004] Therefore, for example, when a predetermined second control condition is satisfied, a second gaming state that is less advantageous to the player than the first gaming state is controlled to change. It is conceivable to configure so as to provide rich games.

[0005] However, simply controlling the game state to the second game state in accordance with the establishment of the second control condition causes a disadvantage that the game is not interesting any more.

A predetermined direct current is supplied from the power supply circuit 53 to the various devices and the control circuit.

FIG. 4 is a flow chart for explaining an operation for generating a large hit, a medium hit and a small hit among the operations of the control circuit shown in FIG.

The program of the flowchart shown in FIG. 4 is executed, for example, once every 2 msec. First, in step S (hereinafter simply referred to as S) 1, the processing of a random number generation routine is performed. This random number ranges from 0 to 999, and starts counting from 0, and when it reaches 999, it operates to count up again from 0. And S
Proceed to 2 to check what numerical value the random number at the time of starting winning is. As a result of the random number check, if the random number is within the range of, for example, 10 to 22, the process proceeds to S3, and it is determined whether the medium / small hit small concentration flag is set. This medium / small hit concentration flag is set in S1 described later.
It is set by 0 and released by S16. If the medium / small hit concentration flag is not set, the process proceeds to S4, and symbols other than the big hit, middle hit, and small hit are set. As a result, the variable display device 4 (see FIG. 1)
Is controlled so that the identification information indicators 7a, 7b and 7c are combinations of identification information other than the big hit, the medium hit and the small hit. On the other hand, if the result of the check in S2 shows that the random number at the time of the start winning is in the range of 23 to 63,
The process proceeds to S5, and if it is within the range of 64-899, the process proceeds to S6. In S5 and S6, it is determined whether or not the medium / small hit concentration flag is set. If not, the process proceeds to S4 and the same control as described above is performed.

On the other hand, as a result of the check in S2, if the random number at the time of the start winning is in the range of 5-9, S1
Going to 0, the medium / small hit concentration flag is set and S11
And a small hit symbol is set. As a result, the stop control is performed so that the identification information displays 7a to 7c (see FIG. 1) of the variable display device become a combination of the small hit identification information.
The probability that the medium / small hit concentration flag is set in S10 is 5/1000 because the process proceeds to S10 when there are five kinds of random numbers of 5 to 9 among 1000 kinds of random numbers of 0 to 999. = 1/200. In addition,
After the small hit concentration flag is set, a symbol of a middle hit or a miss may be set in S11.

When the medium / small hit concentration flag is set in S10, the next time the program of the flowchart shown in FIG. 4 is executed, the random number check in S2 indicates that the random number is 10-22. Is determined in S3 by YES, the process proceeds to S12, and the symbol for the first middle hit is set. As a result, control is performed so that the display result when the variable display device is stopped becomes the first medium hit combination. The probability of occurrence of the first middle hit in S12 is 13/1000 ≒ 1 / 76.9 because the process proceeds to S3 when there are 13 types of random numbers of 10 to 22. On the other hand, as a result of the random number check in S2, the random number is 23
In the case of ~ 63, a determination of YES is made in S5 in the same manner as described above, and the flow advances to S13 to set a second middle hit symbol. The probability of occurrence of the second middle hit in S13 is 41/1000 ≒ 1 / 24.4. further,
As a result of the random number check in S2, if the random number is 64 to 899, the process proceeds to S6, a determination of YES is made in S6, and the process proceeds to S14 to set a small hit symbol. The probability of the small hit symbol being set in S14 is 836/1000 ≒ 1 / 1.2.

On the other hand, as a result of the random number check in S2, if the random number is in the range of 0 to 4,
The process goes to 5 to set a big hit symbol. As a result, control is performed so that the display result when the variable display device is stopped is a combination of symbols with a big hit. Next, the process proceeds to S16, in which the medium / small hit concentration flag is released. The probability that the big hit symbol is set in S15 and the probability that the small / small hit concentration flag is cleared in S16 is 5/1000 = 1.
/ 200. As a result of the cancellation of the flag in S16, NO is determined in S3, S5, and S6. Note that control may be performed so that a specific symbol is set after the medium / small hit concentration flag is released in S16.

On the other hand, the random number at the time of the start winning is 900 to 901
Is satisfied, the first medium hit symbol is set in S7 regardless of whether or not the medium / small hit concentration flag is set. The probability of the first hit set in S7 is 2/1000 = 1/500. If the random numbers at the time of the start winning are 902 to 906,
Regardless of whether the small hit concentration flag is set or not, the symbol of the second middle hit is set in S8. This S
The probability of the second set of symbols per second by 8 is 5/10
00 = 1/200. Furthermore, if the random number at the time of the start winning is 907 to 999, a small hit symbol is set in S9 regardless of whether the medium / small hit concentration flag is set. The probability of the small hit symbol set in S9 is 93/1000 ／ 1 / 10.8.

As described above, if the random number at the time of the start winning is in the range of 10 to 899 and the medium / small hit concentration flag is not set, other than the big hit, the middle hit, and the small hit If the middle / small hit concentration flag is set in S10, the middle / small hit concentration flag is subsequently reset until the middle / small hit concentration flag is released. Random number is 10-2
In the case of 2,23-63,64-899, the first middle hit, the second middle hit, and the small hit symbol are set, respectively, and the game value is given to the player in a concentrated manner. S1
5 allows a relatively large first benefit to the player.
Is given, and the above S11, S12, S13,
By S14, S7, S8 and S9, a second game value smaller than the first game value is provided. The first value providing condition detecting means for detecting that the first value providing condition set so that a relatively large first game value which is profitable for the player can be provided by S1 and S2 is established. It is configured. Further, by S1 and S2, a second game value smaller than the first game value is obtained.
The second value providing condition detecting means for detecting that the second value providing condition set so as to be able to provide the game value is fulfilled. Also, S1 and S1
As a result of the processing of the second step, the random number at the time of the starting prize is 10 to
In the case of 899, the probability of establishment of the second value-giving condition is improved, and once improved, the probability of establishment of the second value-giving condition is reduced when the random number at the time of the start winning is 0 to 4. I do. Therefore, the change condition determining means for determining whether the change condition determined so as to change the probability of the second value-giving condition being satisfied by S1 and S2 is also used. Further, the change condition determining means constituted by S1 and S2 determines that the change condition is satisfied when the random number at the time of the start winning is a predetermined value. Therefore, the change condition determination means constituted by S1 and S2 includes a random number generation means, and determines that the change condition is satisfied when the random number generated from the random number generation means has a predetermined value. And a random number extraction determining means for performing This random number is not necessarily a decimal number, for example, 0-9, A, B,
It may be a hexadecimal number composed of C, D, E, and F. Further, S15, S11, S12, S13, S
According to 14, S7, S8 and S9, the first game value is provided based on the detection output of the first value provision condition detecting means, and the first game value is provided based on the detection output of the second value provision condition detecting means. A game value providing means for providing a second game value is configured. Further, S10, S16, S
3, S5 and S6 constitute an establishment probability changing unit that changes the establishment probability of the first value provision condition based on the determination output of the change condition determination unit. In the present embodiment, the first value-giving condition detecting means and the second value-giving condition detecting means are shared by common steps. However, the present invention is not limited to this. The first value provision condition detection means and the second value provision detection means may be constituted by the steps of (1) and (2).

Next, another embodiment of the present invention will be described. (1) It is satisfied when the change conditions set so that the probability of the second value-giving condition is changed are listed below.

When a big hit occurs, the change condition is satisfied. In this case, the change condition may be satisfied for all of the big hit symbols. In this case, the change condition determining means includes condition satisfaction determining means for detecting that the first value providing condition has been satisfied and determining that the change condition has been satisfied. It is detected that the first control condition for controlling to the first game state which is advantageous for the player is established by the description that the change condition is satisfied for all the symbols of the big hit and the S1 and S2. First control condition detecting means is configured. Then, as described above, the first control condition detecting means determines that a plurality of types of display results of the variable display device are determined in advance in a specific display mode (all of the big hit symbols).
When either of the conditions is satisfied, it is detected that the first control condition is satisfied. On the other hand, the change condition may be satisfied only for a specific big hit symbol (for example, 777). In that case, the change condition determination means may be configured to determine the first
And a condition determining means for determining that the change condition is satisfied by detecting that the value providing condition is satisfied in a certain predetermined state. In this case, a jackpot symbol prediction setting button is provided, for example, so that the player can predict and select and set a specific jackpot symbol that satisfies the change condition, and when the symbol at the time of the jackpot occurrence matches the expectation, The change condition may be satisfied. By S1 and S2, control is performed in a second gaming state (eg, middle hit, small hit) that is a state that is advantageous to the player and that is less advantageous to the player than the first gaming state. A second control condition detecting means for detecting that the second control condition has been satisfied. When the first control condition detecting means detects the establishment of the first control condition, the game state is changed to the first game state in S7 to S9 and S11 to S15, and the second control condition detection is performed. means gaming state control means for the Yu skill state to the second game condition when detecting the establishment of the second control condition is configured. S3, S5, S6, S1
According to 0, S16, and the description of the mode in which the above-mentioned change condition is satisfied, the probability that the second control condition is satisfied changes.
To determine that the change condition set in
An activating condition determining means is configured. Then, the particular jackpot symbols described above (e.g., 777) by description that may be established the change condition for only prior Symbol change condition determining means, said variable display device of the particular display mode In a predetermined special display mode (for example, 7
77) has a function of determining that the condition is satisfied when the condition is satisfied.

The changing condition is satisfied by the pachinko ball passing through a specific passing area where the gaming area is formed in the variable winning ball apparatus. In this case, the change condition determination means detects that the hit ball has passed a specific passage area formed at a position where the hit ball can pass, and determines that the change condition is satisfied. It will include the judgment means.

The change condition is satisfied, for example, when no big hit occurs during a predetermined period. (2) In ending the probability change state in which the change condition is satisfied and the establishment probability of the second value-giving condition changes, the process is ended in the following cases.

The processing is terminated when the power of the pachinko gaming machine is turned off. The process is terminated when a big hit occurs after the change condition is satisfied. At this time, the process may be terminated when the big hit occurs a plurality of times. Further, when the probability change state is once ended, the big hit that occurs after the change condition is satisfied becomes a specific big hit symbol (for example, 7
When a certain condition is satisfied, such as the case including (77), the probability change state may be continued without ending. According to the statement that the probability change state may be continued without ending when the big hit generated after the above-mentioned change condition is satisfied includes a specific big hit symbol (for example, 777), the establishment probability changing means. After the control of the first game state by the game state control means is completed, the second control is performed until the next first control condition is satisfied.

Further, the opening time of the variable winning ball device when a middle hit or a small hit occurs is not limited to the embodiment described above. Further, a predetermined number of prize balls or points may be directly given to the player according to occurrence of a big hit, a medium hit, and a small hit.

(4) The occurrence probabilities of large, medium and small hits are not limited to the above-described embodiment. Further, the range of fluctuation of the probability is not limited to the above-described embodiment. Further, the probability that the probability of occurrence of a medium hit or small hit increases, the probability of occurrence of a medium hit or small hit at the time of improvement, the probability of the end of the improved state, and the fluctuation range of these probabilities are selected and set at the game store (for example, 6 Any one of the probabilities of the stages may be selected and set). At that time, a selection setting unit may be provided for each of the ball game machines, or a selection setting unit may be provided for a centralized management device that centrally manages a plurality of ball game machines installed in the game arcade. .

(5) The player may be notified by a lamp or the like that the probability of occurrence of a middle hit or a small hit has increased.

(6) The structure is such that the probability of occurrence of a big hit changes in accordance with the change of the probability of occurrence of a medium hit or a small hit. For example, when the probability of occurrence of a medium hit or small hit is improving, the probability of occurrence of a big hit is reduced,
When the probability of occurrence of a small hit is reduced, the probability of occurrence of a large hit is improved.

(7) The ball-type game machine of the present invention is constituted by a card-type game machine which can be played using a recording medium such as a magnetic card on which information which can identify the value possessed by the player is recorded. I do.
