The checkout display device 59 requires a ball lending button 57 for requesting lending of game balls, and a request for payment. A checkout button 58 is provided.

  In addition, the payout control device 81 transmits information relating to the winning ball, information indicating the open / closed state of the frames (inner frame 70, front frame 52), etc. to the hall computer 87 via the external connection terminal board 78, as well as the launch control device. A firing stop signal is transmitted to 84.

In this embodiment, the game balls are paid out. However, it is also possible to adopt a sealed configuration in which the prize balls generated according to winnings are stored without being paid out.
The launch control device 84 controls the launch motor 40 to launch a game ball in the game area 3.

  In addition to the payout control device 81, the launch control device 84 receives a rotation amount signal from the launch handle 64, a touch signal from the touch SW 38, and a launch stop signal from the launch stop SW39.

  The rotation amount signal is output when the player operates the firing handle 64, the touch signal is output when the player touches the firing handle 64, and the firing stop switch signal is generated when the player presses the firing stop SW39. Is output. If the touch signal is not input to the launch control device 84, the game ball cannot be fired, and if the launch stop switch signal is input, the game ball can be launched even if the player touches the launch handle 64. There is no such thing.

  The sub-integrated control device 83 receives data and commands transmitted from the main control device 80, distributes them to data for effect display control, sound control, and lamp control, and so on. Is transmitted to the production symbol control device 82, and the sound control and lamp control are distributed to each control part (function unit as a sound control device and a lamp control device) included in itself.

  Then, the function unit as the sound control device controls the sound output from the speaker 66 by operating the sound LSI based on the data for sound control, and the function unit as the lamp control device includes the data for lamp control. Various LEDs and the lamp 28 are controlled by operating the lamp driver based on the above.

Further, a game SW 67 is connected to the sub integrated control device 83, and when the player operates the game SW 67, the signal is input to the sub integrated control device 83.
Bi-directional communication is possible between the sub integrated control device 83 and the production symbol control device 82.

  The effect symbol control device 82 displays the effect symbol display based on the data and commands received from the sub integrated control device 83 (both those transmitted from the main control device 80 and those generated by the sub integrated control device 83). The device 6 is controlled to display an effect screen such as an effect symbol change display (symbol effect).

[Description of operation]
(1) About outline Next, operation | movement of the pachinko machine 50 in 1st Embodiment is demonstrated.

  The pachinko machine 50 has a probability changing function for increasing the winning probability in the big lottery, and increases the winning probability of the normal symbol lottery, and increases the opening time of the second starting port 12 when winning in the normal symbol lottery. An open extension function (shortening function) that facilitates entry into the second start port 12 is provided by a method such as shortening the variable display time on the normal symbol display device 7 when the symbol lottery is performed. .

  Further, when the pachinko machine 50 wins the big hit lottery, a 15R big hit game is played. And 14R of the jackpot game is a privilege period, and the first probability variation port 13 provided in the first grand prize winning port 20 or the second probability variation port 15 provided in the second major prize winning port 21 during the privilege period. If a ball is entered in any of the above, after the big hit game is finished, a privilege is given, and the state is changed to a probability change state and a time reduction state (probability change + time reduction state).

  Of course, the number of rounds of the jackpot game is not limited to 15R. Also, the privilege period is not limited to 14R, and one or more other rounds may be the privilege period, or all rounds in the big hit game may be the privilege period. Moreover, it is good also considering a period from the predetermined timing of a predetermined round to the predetermined timing in the round after the said round as a privilege period.

  More specifically, when a privilege is granted, the probability variation + short time state continues while 100 big hit lotteries are performed. Note that the content of the privilege is not limited to this, and the number of continuations of the probability variation + short-time state may be a number other than 100, or the state shifts to either the probability variation state or the short-time state. It is good also as a structure.

  Further, during the bonus period (14R), when the first grand prize opening 20 is opened, the first probability changing opening 13 is opened or closed by the first shutter 14 one or more times, and the second big prize opening 21 is opened. Then, the second probability opening 15 is opened and closed by the second shutter 16 one or more times. Then, the probability of entering the probability variation opening is determined by the shutter opening / closing pattern.

  In addition, when it is short, it is possible to make it impossible (or substantially impossible) to enter the probability variation opening, and when it is long, it is easy to enter the probability variation opening. In addition, it is possible to enter the probability variation mouth with a certain probability when the short is, and to enter the probability variation mouth with a higher probability than when the short is.

  In addition, for example, the first grand prize opening 20 is short and the second big prize opening 21 is long and the operation is determined in advance, and it is also possible to select which big prize opening is to be opened at 14R according to the winning symbol. It is done.

  If this is the case, the winning rate to the second probability variation opening 15 set for the long operation is higher than the first probability variation opening 13 for which the short operation is set even if the opening time is the same, and the opening time is still Since they are the same, the number of winning prize balls can be the same.

  In the jackpot game corresponding to the first special figure, when the first grand prize opening 20 is opened during the bonus period, the opening / closing pattern of the first probability changing opening 13 becomes short, and the second big prize hall during the bonus period. When 21 is opened, the opening / closing pattern of the second probability opening 15 is long (see FIG. 16A). For this reason, in the jackpot game corresponding to the first special figure, whether or not to shift to the probable change + short time state depending on which of the first and second big winning openings 20, 21 is released during the privilege period (or It is determined whether or not it is easy to shift to a certain change + short time state).

  On the other hand, in the jackpot game corresponding to the second special figure, the opening / closing pattern of the probable opening becomes long regardless of which of the first and second grand prize winning openings 20 and 21 is opened during the bonus period (see FIG. 16A). ). For this reason, there is a high possibility that the player will enter the probability change mouth during the big hit game and shift to the probability change state. Once the probability change + short time state is reached, the state is likely to continue. Of course, even in the jackpot game corresponding to the second special figure, the opening / closing pattern of the first probability changing opening 13 may be short and the opening / closing pattern of the second probability changing opening 15 may be long.

  In addition to this, when the first grand prize opening 20 is opened during the bonus period, the opening / closing pattern of the first probability changing opening 13 is always short and the second big prize opening 21 is opened. The opening / closing pattern of the second probability variation opening 15 may be always long.

In such a case, as shown in FIG. 16 (b), a special winning opening that is to be released during the bonus period (14R) may be determined according to the type of special figure corresponding to the big hit game or the winning symbol.
In addition, as shown in FIG. 17, a special winning opening that is to be released during the bonus period (14 </ b> R) may be determined according to the type of special figure corresponding to the jackpot game. Further, at this time, when winning in the first special figure, the first big winning opening 20 is opened in all rounds of the big hit game, and when winning in the second special figure, The second grand prize opening 21 may be opened in all rounds.

  According to such a configuration, when it is not in the short-time state, the first starting port 11 arranged in the left-handed area is aimed and even in the big hit game when the big hit lottery is won, the left-handed area is continuously aimed and the first The game progresses in such a way as to enter the big prize opening 20. In other words, if the time is not short, the game is always left-handed.

  On the other hand, when the time is short, the second starting port 12 arranged in the right-handed area is aimed and even when the big hit lottery is won, the right-handed area is continuously hit to the second big winning hole 21. The game progresses as if entering a ball. In other words, during the short-time state, the game always proceeds with a right hand strike.

  For this reason, when it is not the short-time state, only the big hit lottery based on the entry to the first start port 11 is performed, and when it is the short-time state, only the big hit lottery based on the entry to the second start port 12 is performed. Thereby, the probability of winning a big hit lottery or the probability of giving a privilege can be made different depending on whether or not the time is short.

Whether the player is left-handed or right-handed is determined depending on whether the time is short or not, and it is not necessary to switch the way of hitting, so that the player is not bothered.
In addition, when winning in the first special figure, it is difficult to enter the probable entrance during the special period, and it is difficult to give a special benefit. It becomes easy to enter the probable opening at, and a privilege is easily given. For this reason, when it is not the time-short state, it is difficult to shift to the probability change + time-short state.

  Of course, conversely, when the first grand prize opening 20 is opened during the bonus period, the opening / closing pattern of the first probability changing opening 13 is always long, and when the second big prize opening 21 is opened, The opening / closing pattern of the second probability variation opening 15 may be always short-circuited. Even in such a case, as shown in FIG. 16 (b), a special winning opening that is to be released during the bonus period (14R) may be determined according to the type of special chart or winning symbol.

  Also in such a case, as shown in FIG. 17, a special winning opening that is to be released during the bonus period (14R) may be determined according to the type of special drawing. In the event of a win, the first big prize opening 20 is opened in all rounds of the jackpot game, and in the case of a win in the second special figure, the second big prize opening 21 is opened in all rounds of the jackpot game. You may do it.

  As a result, when winning in the first special figure, it is easy to enter the probable opening in the special period, and the bonus is easy to be given, but in the case of winning in the second special figure, the special period It becomes difficult to enter the probabilistic entrance at, and it becomes difficult to give a privilege. For this reason, when it is not the time-short state, it is easy to shift to the probability change + time-short state, but it is difficult to continue this state after the transition to the probability change + time-short state.

  Moreover, in 1st Embodiment, when entering the 1st, 2nd probability variation opening | mouths 13 and 15, the probability variation + time-short state over 100 times will continue as a privilege, but in any of the 1st and 2nd probability variation variations 13 and 15 Depending on whether the ball has entered, the privilege content may be changed. Specifically, for example, when entering the first probability variation opening 13, the transition to the probability variation state is regarded as the benefit content, and when entering the second probability variation aperture 15, the transition to the probability variation + short time state is performed. It is good also as a privilege content. In addition, for example, when entering the first probability variation opening 13, the privilege content is to continue the probability variation + short-time state for X times, and when entering the second probability variation aperture 15, it is more than X times. It is good also as a privilege content to continue a probabilistic + time-short state many times.

It is also possible to set a different probability variation + shortening state depending on the winning symbol, to set only the number of probability variation states, or to set the number of shortening states.
In this way, it is possible to play a game with high interest because it recognizes the granted content after the big hit game with the winning symbol and aims at a probable change during the privilege period.

(7) About production screen Next, in the pachinko machine 50 of 1st Embodiment, the production screen displayed on the production symbol display apparatus 6 during a game is demonstrated.

  The sub integrated control device 83 of the pachinko machine 50 controls the effect symbol control device 82 in accordance with a command from the main control device 80 and displays various effect screens on the effect symbol display device 6. In conjunction with the display of the effect screen, various sounds are output through the speaker 66, and various LEDs and lamps 28 are lit.

  Specifically, the sub integrated control device 83 performs a symbol effect accompanied by a change display of the effect symbol, a display of the hold symbol, and the like on the effect symbol display device 6 in accordance with a command from the main control device 80. In addition, during the big hit game, the number of rounds, the number of balls entered into the big prize opening, and the like are displayed, and a character called Tatsuyoshi Bear is displayed.

  When the bonus period (14R) is reached, a message prompting the player to hit the odds opening is displayed, and when entering the odds opening, a message is displayed indicating that the game will shift to the probable state after the big hit game is finished (FIG. 18 (a)). reference). In addition, you may display how to hit (whether right-handed or left-handed) to enter the big winning opening that is opened during the privilege period.

  Moreover, when it becomes 13R, for example, if the 2nd big prize opening 21 is opened during the privilege period, it shifts to the super probability variation (probability variation + short-time state) (the probability of transition to the super probability variation is high). To display the player's expectation (see FIG. 18B).

  In addition, as a method of encouraging a sense of expectation, it is conceivable that a mini game is played during a big hit game, and the mini game is cleared and which is released during the bonus period. In addition to during the big hit game, it is possible to indicate which will be released in the bonus period when the big hit is made in the display mode of the reserved memory, during the change of the design, or at various timings.

[Second Embodiment]
The pachinko machine 50 according to the second embodiment has the same configuration as that of the first embodiment, but the eight chucker 17 is provided directly below the center case 5 which is a left-handed region, instead of the first start port 11. This is different from the provided points in the configuration of the special winning opening and the probability variation opening (see FIG. 19).

  In the inside of the eight chucker 17, the first starting port 11 and the second starting port 12, and the game balls that have entered the ball are guided to one of the first and second starting ports 11 and 12, and the ball has entered. Due to this, there is provided a sorting blade 17a for switching a starting port to which a game ball is guided. The eight chucker 17 causes the game balls that have entered the device to enter the first start port 11 and the second start port 12 alternately.

  In the second embodiment, the configurations of the second grand prize winning port 21 and the second probability variation port 15 are the same as those in the first embodiment, but the configurations of the first major prize winning port 20 and the first probability variation port 13 are the first. This is different from the embodiment.

  Specifically, a ball entrance is provided at the bottom of the first big prize opening 20, and a first shutter 14 for opening and closing the ball entrance is provided. An inclination is formed at the bottom, and the game ball that has entered the first grand prize opening 20 flows down toward the entrance, and if the entrance is open, the game ball is entered into the entrance. Enter the ball. On the other hand, if the entrance is closed, the game ball does not enter the entrance, but enters the exit (not shown) provided in the first grand prize opening 20. In addition, the entrance is connected to the first croon 13c in which three distribution openings are formed, and one of these distribution openings 13c-1 is connected to the first probability variation opening 13 ( FIG. 20).

  During the bonus period (14R) during the big hit game, the first shutter 14 is opened, and it is possible to enter the entrance of the first grand prize opening 20, and the first grand prize opening 20 is entered during the bonus period. The ball opening is closed by the first shutter 14.

  Then, when the first grand prize opening 20 is opened during the privilege period and the game ball enters the first big prize opening 20, the game ball enters the first croon 13c from the ball entrance, and further, the game ball If the ball enters the distribution opening 13c-1 connected to the first probability changing opening 13, a privilege is granted after the big hit game. However, even if the game ball enters the other distribution port 13c-2, no privilege is given.

  As described above, the first probability variation opening 13 has a ball entering probability determined by the first croon 13c, and the second probability variation port 15 has a ball entering probability determined by the second shutter 16 as in the first embodiment. The probability of entering the first probability variation opening 13 may be larger or smaller than the probability of entering the second probability variation aperture 15. As in the first embodiment, the special winning slot for which the bonus period is to be opened is determined by the type of special drawing for which the big winning lottery has been performed and the winning symbol, and the probability varies depending on which winning winning opening is opened. It is determined whether or not to shift to the + time reduction state (or whether or not it becomes easy to change to the + time reduction state).

  A similar croon may be provided at the second grand prize winning port 21 and the second probability changing port 15. That is, at the bottom of the second grand prize winning opening 21, a ball entrance connected to the second croon 15c may be provided, and a second shutter 16 for opening and closing the ball entrance may be provided. Then, two distribution ports may be provided in the second croon 15c, and one of these distribution ports 15c-1 may be connected to the second probability variation port 15 (FIG. 21).

  During the jackpot game, the second shutter 16 is opened during the bonus period, and the player can enter the entrance of the second grand prize opening 21. The mouth is closed by the second shutter 16. When the second grand prize opening 21 is opened during the privilege period, and a game ball enters the second big prize opening 21, the game ball enters the second croon 15c. When a game ball that has entered the second cruiser 15c enters the distribution port 15c-1 connected to the second probability change port 15, a privilege is given after the big hit game, and even if the game ball enters the other distribution port 15c-2 , No benefits are granted.

If a game ball enters the second grand prize opening 21 while the second shutter 16 is closed, the game ball enters a discharge port (not shown) and does not reach the second croon 15c. .
According to such a configuration, there are three distribution openings of the first croon 13c provided in the first big winning opening 20, and distribution openings of the second croon 15c provided in the second big winning opening 21. Since there are two, the first probability variation opening 13 has a lower probability of entering than the second probability variation opening 15. For this reason, when the first grand prize opening 20 is opened during the bonus period, the probability that the bonus is granted is lower than when the second big prize opening 21 is opened.

  Of course, the number of distribution ports provided in each cloon is not limited to the above-described number, and the number of distribution ports of the first cron 13c is set to be more than the number of distribution ports of the second cron 15c. It may be less. In addition, the probability of entering the distribution port connected to the probability variation port may be adjusted according to the shape, inclination, etc. of the croon, not limited to the number of distribution ports provided in the croon.

  In addition, the configuration of the first grand prize opening 20 and the first probability variation opening 13 may be the same as that of the first embodiment, and the second big prize opening 21 may include the above-described second croon 15c. In such a case, the first probability variation opening 13 has a ball entry probability determined by the first shutter 14 in the same manner as in the first embodiment, and the second probability variation hole 15 has a ball entry probability due to the second croon 15c. Determined. The probability of entering the first probability variation opening 13 may be larger or smaller than the probability of entering the second probability variation aperture 15.

Further, the configurations of the first grand prize winning port 20 and the first probability variation port 13 and the configurations of the second major prize winning port 21 and the second probability variation port 15 may be the same as those in the first embodiment.
[Modification]
Next, a modified example of the pachinko machine 50 according to the first embodiment will be described.

  In the modification, the limiter function is activated when the number of consecutive occurrences of the jackpot game that has shifted to the probability change + short-time state reaches a predetermined upper limit number, and then the bonus period (14R) of the jackpot game that has occurred thereafter. Even if the ball enters the probability variation mouth, it does not shift to the probability variation + short time state.

  Specifically, as shown in the table of FIG. 22, the privilege period release target is determined according to the winning symbol. In the jackpot game corresponding to the first special figure, when the opening period of the bonus period is the first big prize opening 20, the opening / closing pattern of the shutter is short, and the opening period of the bonus period is the second big prize opening 21 The shutter opening / closing pattern is long. On the other hand, in the jackpot game corresponding to the second special figure, the shutter opening / closing pattern is long regardless of the special winning opening to be opened during the bonus period.

  And before the operation of the limiter function, when the ball enters the first probability changing hole 13, it shifts to the probability changing state after the big hit game ends as a privilege, and when the ball enters the second probability changing port 15, the privilege Then, after the big hit game ends, it shifts to a certain change + short time state. On the other hand, when the limiter function is activated, even if the ball enters the first probability changing opening 13, no privilege is given. (See FIG. 22).

  In the table of FIG. 22, “high / support” indicates the benefit content that shifts to the probability change + short-time state, “high / none” indicates the privilege content that transitions to the probability change state, and “low / support” indicates the time shortening. The privilege content which shifts to the state is shown. “Low / None” indicates that no privilege is granted.

  In addition, the privilege content at the time of entering the probability changing opening before the operation of the limiter function may be as follows, while the privilege content at the time of entering the probability changing aperture at the time of the operation of the limiter function is described above. .

  That is, in the jackpot game corresponding to the first special figure, when the ball enters the first probability variation slot 13, as a privilege, when the game shifts to the probability variation state after the jackpot game ends and enters the second probability variation slot 15. As a privilege, after the jackpot game is over, it may shift to a probable change + short time state. On the other hand, in the jackpot game corresponding to the second special figure, when the player enters the first and second odds-and-evens 15, as a privilege, after the jackpot game is over, the game may shift to the certainty + short time state ( (See FIG. 23).

  Also, in the pachinko machine 50 of the second embodiment, the same limiter function is provided, and the privilege period release target, the privilege content before the limiter operation, and the privilege content at the time of the limiter operation are the same as in the modification example. Also good.

  FIG. 24 shows an effect screen when a big hit game is played in the pachinko machine 50 according to the modification. During the jackpot game of the modified example, when it becomes 13R, when the second big winning opening 21 is opened during the bonus period (14R) on the effect screen, the time shifts to the short time state (the time shifts to the short time state). May be displayed).

[effect]
According to the pachinko machine 50 of the first and second embodiments, when the first grand prize opening 20 is opened during the bonus period (14R) during the big hit game and when the second big prize opening 21 is opened. The probability that a game ball that has entered the grand prize opening will enter the probability variation entrance is different. For this reason, the probability that a privilege will be given differs depending on the type of special winning opening opened during the privilege period.

  As a result, whether or not it becomes easy to grant a privilege depending on which of the large winning opening is opened while allowing the player to acquire a large number of winning balls while opening the large winning opening for a long period of the privilege period ( Or, whether or not a privilege is granted can be determined. Therefore, it is possible to adjust the probability that a privilege is given after the big hit game without reducing the number of prize balls that can be obtained in the big hit game.

  In addition, the player plays a big hit game while hoping to open a big prize opening with a higher probability of entering the odds opening during the benefit period, and if the player has a low probability of entering the odds opening during the benefit period Even if the game is released, the game can be performed while the player wants the game ball to enter the probable entrance, and the interest of the game can be enhanced.

[Other Embodiments]
(1) In the pachinko machine 50 according to the first embodiment, the first start port 11 and the first big winning port 20 are arranged in the left-handed region, and the second start port 12 and the normal gate in the right-handed region. 22 and a second grand prize winning port 21 are arranged. However, the present invention is not limited to this, and the second starting port 12, the ordinary gate 22, and the second big winning port 21 are arranged in the left-handed region, and the first starting port 11 and the first starting port 21 are disposed in the right-handed region. A big prize opening 20 may be arranged.

Further, in the pachinko machine 50 according to the first embodiment, an eight chucker 17 similar to that of the second embodiment may be provided instead of the first start port 11.
Further, in the pachinko machine 50 according to the second embodiment, the eight chucker 17 and the first big winning opening 20 are arranged in the left-handed area, and the second starting port 12, the normal gate 22 in the right-handed area, The second grand prize opening 21 is arranged. However, the present invention is not limited to this, and the second starting port 12, the ordinary gate 22, and the second big winning port 21 are arranged in the left-handed region, and the eight chucker 17 and the first big winner are arranged in the right-handed region. A mouth 20 may be provided.

Even if it has such a structure, the same effect can be acquired.
(2) Further, in the pachinko machine 50 according to the first embodiment, the probability of entering the first probability variation opening 13 and the second probability variation opening 15 in the privilege period (14R) is determined by the shutter opening / closing pattern. However, the present invention is not limited to this, and in the same manner as in the second embodiment, the probability of entering a ball into the probability variation opening is adjusted by providing a cleon in one or both of the first grand prize opening 20 and the second major prize opening 21. May be. Even in such a case, the same effect can be obtained.

  (3) Further, in the pachinko machine 50 according to the first and second embodiments, the course is closed by the shutter except during the privilege period (14R), and it is impossible to enter the probable entrance. However, the present invention is not limited to this, and it is always possible to enter the probability variation entrance, and only the probability variation entrance detected during the benefit period is valid, and the probability variation entrance detected outside the benefit period is invalid. It is also good. Even in such a case, the same effect can be obtained.

  (4) Also, in the first embodiment, during the jackpot game, the probability of entering the first and second probability variation ports 13 and 15 in the bonus period (14R) is determined by the shutter opening / closing pattern. It is good also as a structure which determines the entrance probability of a probability variation mouth with a pattern.

  Specifically, during the big hit game, each probability change opening is closed by the shutter except during the bonus period, and it is impossible to enter each probability change opening. On the other hand, during the bonus period, one of the first and second grand prize winning holes 20 and 21 is opened and closed with a predetermined opening and closing pattern, and each probability changing mouth is opened, and a game ball entering the big prize winning opening is Try to enter the probable entrance.

  The opening and closing patterns of the grand prize opening include a long opening period with a relatively high probability of entering the grand prize opening and a short opening period with a relatively low probability of entering the grand prize opening with a relatively low probability. And the probability of entering into the probability changing mouth may be adjusted by opening the big winning opening with a long or short opening / closing pattern during the bonus period. Note that, in the short opening / closing pattern, the special winning opening may be opened and closed so that it is substantially impossible to enter the special winning opening.

At this time, similarly to the above-described embodiment, the opening / closing pattern of the big prize opening during the privilege period may be determined according to the type of the special symbol and the winning symbol.
In addition, for example, the first grand prize opening 20 is long, the second big prize opening 21 is short, and the opening / closing pattern of each big prize opening during the privilege period is determined in advance, and the big prize opening opened during the privilege period. Depending on the type, it may be possible to determine whether or not a privilege is granted.

Similarly to the above-described embodiment, the content of the privilege to be given may be different depending on whether the ball enters the first probability variation opening 13 or the second probability variation opening 15.
Even in such a case, it is possible to adjust the probability that a privilege will be granted after a big hit game.
