Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pinball game machine represented by a pachinko game machine, a coin game machine, etc. This invention relates to a pinball game machine in which you can play a game by hitting.

"Prior Art" In this type of pinball game machine, there is a conventionally known technique in which, for example, the display result of a variable display device provided in the game area is changed to a predetermined display result (e.g. 777), a relatively large first gaming value such as a jackpot is awarded to the player, and the variable display device changes to a predetermined display state ( For example, the system is configured to award a second gaming value smaller than the first gaming value to the player based on the fulfillment of a second value awarding condition such as "Bell Bell Bell". Since the first gaming value is a relatively large gaming value, this first gaming value is a relatively large gaming value.
If the probability of the first value-giving condition being met is too high, the gaming hall will be in the red, so the probability of the first value-giving condition being met is usually set relatively low.

[Problems to be Solved by the Invention] As described above, in the conventional pinball game machine, since the probability that the first value imparting condition is met is not so high, the first value imparting condition is not satisfied once. If this is true, the player often stops playing the game and returns home, anticipating that the first value-giving condition will not be met for a while. Further, if the first value-giving condition is not satisfied for a certain period of time, the player often stops playing the game and returns home, thinking that the first value-giving condition cannot be satisfied so easily. In game halls, when players leave, empty spaces become noticeable, causing the inconvenience that the inside of the game hall loses its vibrancy.

Therefore, for example, if the first value granting condition is satisfied once, the probability that the first value granting condition will be satisfied next time is increased. It is also conceivable to effectively control the probability that the granting conditions will be met in order to keep players attached to the gaming machine as much as possible.

However, by simply changing the probability of the first value-giving condition being satisfied, players' interest will be focused only on the fulfillment of the first value-giving condition, making the normal game monotonous. This causes the inconvenience of

In view of the above-mentioned circumstances, the present invention, while being able to keep players connected to gaming machines as much as possible, also has the inconvenience that the normal game except when the first value imparting condition is satisfied becomes monotonous. The purpose is to provide a pinball game machine that does not require a pinball game machine.

[Means for Solving the Problems] The present invention is a pinball game machine that includes a game area and plays a game by hitting a ball into the game area, which provides a relatively large first advantage that is profitable for the player. a first value imparting condition detection means for detecting that a first value imparting condition determined to be able to impart a gaming value of; a second value imparting condition detecting means for detecting that a second value imparting condition determined to enable the player to obtain the first gaming value based on a detection output of the first value imparting condition detecting means; and a gaming value imparting means for imparting the second gaming value based on the detection output of the second value imparting condition detection means, and a probability that the second value imparting condition is established is determined to vary. a change condition determining means for determining whether the change condition determined has been satisfied; and an establishment probability changing means for changing the probability that the second value imparting condition is satisfied based on a determination output of the change condition determining means. It is characterized by

[Function] According to the present invention as set forth in claim 1, if the first value imparting condition is satisfied, a relatively large first value that is advantageous to the player is imparted, and the second value imparting condition is satisfied. If established, a second gaming value smaller than the first gaming value will be awarded. Then, by the function of the change condition determination means,
It is determined that a change condition that is determined to change the probability of the second value-adding condition being met is satisfied, and control is performed so that the probability of the second value-giving condition being met is changed based on the determination output. be done.

In other words, since the probability of the second value granting condition being met is controlled to change depending on the establishment of the changing condition, by setting the changing condition to a desired value, you can increase the chance of giving gaming value and make it more effective. Although it is possible to keep players connected to the gaming machine, it is possible to keep the players attached to the gaming machine, but the game becomes monotonous due to the fact that players are distracted by the provision of gaming value during normal gaming other than when the first value awarding condition is met. can be prevented.

The present invention as set forth in claim 2 provides, in addition to the effects of the invention as set forth in claim 1, a first game value familiar to players, which is determined to be able to satisfy the change condition and provide the first game value. is consistent with the establishment of the value-adding condition.

The present invention as set forth in claim 3 provides, in addition to the effect of the invention as set forth in claim 1, a first game value familiar to players, in which the changing condition is determined to be able to provide the first game value. It is established when the value imparting condition is satisfied in a certain predetermined manner.

In the present invention as set forth in claim 4, in addition to the effect of the invention as set forth in claim 1, the change condition is satisfied when the random number generated from the random number generating means is a predetermined value.

In the present invention as set forth in claim 5, in addition to the effect of the invention as set forth in claim 1, the changing condition is established when the hit ball passes through a specific passage area.

[Embodiments of the invention] Next, embodiments of the present invention will be described in detail based on the drawings.

(2) In terminating the probability changing state in which the changing condition is met and the probability of establishing the second value-adding condition has changed, the probability changing state is terminated in the following cases.

■ Shut down the pachinko machine when it is turned off.

(2) If a jackpot occurs after the above-mentioned change conditions are satisfied, the process is terminated. At that time, the game may be terminated when a jackpot occurs multiple times. Further, when ending the probability change state -1, if a certain condition is satisfied, such as a case where a jackpot that occurs after the change condition is satisfied includes a specific jackpot symbol (for example, 777), the probability changes. The state may be continued without being terminated.

■ A predetermined period of time has elapsed after the change condition was met, or the number of times the second game value is given or the number of variable displays with the probability changed has reached a predetermined number, or one of both of these conditions. The probability change state is terminated when either of the conditions is satisfied, whichever comes first. In this case, when a certain condition is met, such as when a lottery is conducted to determine whether or not to continue the probability change state at the end of the limit number of times or time limit, and data indicating that the probability change state is to be continued is extracted. The probability change state may be continued.

(2) After the change condition is met, the probability change state is ended based on the extraction of data determined to end the probability change state. In that case, the combination of symbols displayed based on the extracted data may be a specific symbol combination determined to end (for example, "Fl"
O) may be used.

■ The probability change state is terminated when the pachinko balls pass through a specific passage area in the game area or the variable winning ball device.

■ The probability change state is terminated when the pachinko ball does not pass through a specific passage area formed in the game area or the variable winning ball device.

■ The probability change state is terminated because the starting winning memory is lost.
