Description

  The present invention relates to a pachinko gaming machine, and in particular, when a starting condition is established, a random number is acquired and a jackpot lottery is performed. When a specific random number is acquired and won, a special gaming state advantageous to the player (bonus) is obtained. When the random number is a predetermined random number, the present invention relates to a pachinko gaming machine to which a privilege that gives a high probability of winning at the next jackpot lottery is given.

  Conventionally, for example, when a game ball enters a specific start winning opening, a random number is obtained and a big hit lottery is performed, and the three rows of symbols on the symbol display device are displayed in a variable manner so as to flow from top to bottom, and a big win is won. In this case, three rows of symbols stop in line with a predetermined symbol on a predetermined judgment line, become a special game state, that is, a big hit, and a large winning opening of the variable winning device opens, and a lot of game balls are won. Amusement machines are widely used.

  As this type of pachinko gaming machine, as described in Patent Document 1 below, when the acquired random number is a specific random number and the jackpot stop symbol is a specific symbol such as “777”, There is known a pachinko gaming machine that operates so as to give a privilege of probability fluctuation that makes the winning probability at the time of the big hit lottery higher than usual.

In this pachinko machine, when a big hit with a probability variation bonus occurs, there is a high possibility that the big hit will occur continuously, and the number of times (number of rounds) that the big winning opening of the variable prize winning device is opened by the occurrence of the big win is increased. Many are executed, and a lot of prize balls are paid out. Further, in a pachinko gaming machine that generates a big hit (probability variation state) with this kind of probability variation benefit, conventionally, when the probability variation state occurs, the probability variation state is notified to the player by, for example, lighting a lamp. It has become mainstream.

  On the other hand, in the above-mentioned Patent Document 2, when the probability variation state is entered, when the player presses the probability variation display button, the probability variation state is displayed to the player, and the player displays the probability variation state. A pachinko gaming machine has also been proposed in which notification of the probability variation state can be selected.

  However, in the former pachinko gaming machine, if the probability variation state does not occur even if a big hit occurs, the player knows that directly, and there is a problem that the interest in the pachinko game is likely to be reduced. Even in the latter pachinko machine, when the player presses the probability change display button, the probability variation state is displayed to the player, so the button operation is complicated for the player and the probability is also increased. If the player is not in a fluctuating state, the player can easily find out that, so there is a problem that the interest in the pachinko game is likely to be reduced.

  The present invention has been made in view of the above points, and even when the probability variation state (high probability mode state) is not notified, the player with respect to the game can have the expectation of the probability variation state. An object is to provide a pachinko machine that can improve the interest of the game.

In order to achieve the above object, a pachinko gaming machine according to claim 1 of the present invention includes a symbol display device that variably displays symbols when a start condition is established, and a lottery means for obtaining a random number and performing a big hit lottery when the start condition is established. , Get a jackpot random number, win the jackpot lottery, and when the symbols on the symbol display device stop in line with the predetermined arrangement, it will be a jackpot state, the jackpot random number with probability fluctuation in the jackpot lottery by lottery means In the pachinko machine where the winning probability at the time of the jackpot lottery is higher than normal, the game ball is specified on the game board when winning the jackpot with probability fluctuation and winning. Specific gate detection means for detecting that the gate has passed, and high to determine whether the winning probability at the big hit lottery is in a high probability mode state where the probability is higher than usual. A rate mode determining means, a notification lottery means acquires a random number from the random number generator performs whether lottery informing high possibility mode state, when the high possibility mode determining means determines that the high possibility mode state When the specific gate detection means detects the passing of the specific gate of the game ball and the notification lottery means winning a lottery that acquires a specific random number and notifies the high probability mode, the decoration lamp is turned on / flashes or the speaker A high-probability notification means for generating a voice from and notifying a high-probability mode;
It is provided with.

The invention of claim 2 is the pachinko game machine of the first aspect, the auxiliary probability display means for displaying to distinguish both normal normal probability mode and the high possibility mode of provided supplementarily, the auxiliary probability Display The means is characterized in that a plurality of small lamps are turned on, blinked, or turned off to distinguish and display both the normal probability mode and the high probability mode in a manner that is not easily recognized by the player.

  In the pachinko gaming machine configured as described above, when the start condition is satisfied during the game, the symbols on the symbol display device are displayed in a variable manner. When the symbols are stopped according to a predetermined symbol, a big hit state in which a large number of game balls can be obtained is achieved. . At this time, if the big hit stop symbol is a specific symbol such as “777”, a benefit of probability fluctuation is given that makes the winning probability at the next big hit lottery higher than usual.

On the other hand, the game ball launched on the game board passes through a specific gate, the passage of the gate is detected, and it is determined that the high probability mode state in which the winning probability at the big hit lottery is higher than usual. In addition, when a lottery for determining whether to notify the high probability mode state is won, the high probability mode is notified by lamp lighting effects, voice effects, and the like.

Thus, when a game ball passes a specific gate and wins a lottery notification in the high probability mode state, the high probability mode is notified and does not pass the specific gate even in the high probability mode state. Or, if the notification lottery is not won, the high probability mode is not notified, so the passing of the game ball to a specific gate is meaningful, and the player launches the game ball aiming at the specific gate. Thus, the game characteristics of the pachinko game can be further improved. In addition, the player recognizes the transition to the high probability mode, that is, the probability variation state as a result of passing the game ball through a specific gate, and can enjoy the game with great expectation of the big hit after this. .

On the other hand, regardless of the state of the high probability mode, if the game ball does not pass the specific gate, or if it does not win the notification lottery even if it passes, the high probability mode is not notified, so the player can Until you win the notification lottery, you can play the game with expectation, and even if the high probability mode is not notified, there is a notification of the high probability mode when the next gate passes The player can be expected.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of a pachinko gaming machine.

  As shown in FIG. 1, a symbol display device 10 having a display 10 a made up of a color liquid crystal display or the like is disposed in the center of the game area of the game board 3. The symbol display device 10 is provided with a reserved ball display portion 10c for displaying a reserved ball at the lower portion of the display 10a. Further, on the display 10a of the symbol display device 10, for example, a plurality of symbols arranged in three rows (the symbols that vary based on the lottery when the start condition is established) are cyclically moved from top to bottom in order to be variably displayed. . In addition, a notice effect screen for a big hit or reach, a big hit effect screen, and the like are also displayed on the display 10a.

  Furthermore, as shown in FIG. 1, a normal symbol display 27 is provided on the right side of the symbol display device 10. The normal symbol display 27 continuously displays, for example, one-digit numbers 3 to 7 at a high speed when the game ball passes the passing gate 4. Then, when the symbol (number) at the time of stopping after a predetermined time elapses is “7”, for example, the blade 13c of the start winning port 13 which is an ordinary electric accessory opens for a predetermined time (for example, 0.5 seconds), and starts. It operates so that a game ball can easily enter the winning opening 13.

  The start winning opening 13 is provided below the central position of the symbol display device 10, and the normal winning opening 12 and the passing gate 4 are arranged on both sides thereof. The passing gate 4 corresponds to the specific gate, and when the game ball passes through the passing gate 4 in the high probability mode state, the player is notified of the high probability mode by lighting a lamp or the like.

  A variable winning device 11 is provided below the start winning opening 13. The start winning opening 13 has an openable / closable blade 13c. The blade is opened and closed by the start winning opening solenoid 13b, and the winning ball is detected by the start winning opening detector 14 disposed on the inside thereof. The variable winning device 11 is provided with an opening / closing member 11a for opening and closing the big winning opening so as to be opened and closed by a large winning opening solenoid 11c.

  A special winning opening called a V zone is provided in the large winning opening of the variable winning device 11, and a continuous winning opening detector 19 for detecting a ball that has won the specific winning opening is provided on the inside thereof. A large winning opening detector 18 is provided for detecting a ball that has won a prize in the mouth. A counter that counts the number of winning balls won in the winning opening is provided in, for example, a specific memory area of the RAM, and when the count value reaches 9, for example, the opening / closing member 11a of the variable winning device 11 is closed. One opening of the opening / closing member 11a is defined as one round, and the round is renewed when a winning is made in a specific winning opening within a predetermined time, and the opening / closing member 11a is opened up to 16 rounds, that is, 16 times. It should be noted that the special winning opening of the variable winning device 11 can be automatically updated up to a predetermined round without providing a specific winning opening.

  Further, when the game ball passes through the passing gates 4 on both sides and the special extension mode is set, the blade 13c of the start winning opening 13 is longer than the normal time by the start winning opening solenoid 13b (for example, 5 seconds). ) Works to open.

  As shown in FIG. 2, the control system of the pachinko machine controls the basic operation of the pachinko game and outputs a symbol change command when the start condition is established, and the symbol change from the main controller 20 A symbol control unit 30 that inputs a command and performs variable display control of the symbol, a voice control unit 40 that controls command generation by inputting command data from the main control unit 20, and command data from the main control unit 20 The lamp control unit 50 controls lighting of the decoration lamp.

  The main control unit 20 performs a control process associated with a pachinko game based on a prestored program, a read-only ROM 22 for storing the game program, temporarily stores data, and functions as a work area for the CPU 21 And a RAM 23 and an input / output circuit 24. In the RAM 23, an area for counting and storing the number of held winning balls as an on-hold counter and an area for counting and storing the number of symbol fluctuations are set. The hold counter counts up to four winning balls from 1 to 4, for example, and stores them. The value of the holding counter is displayed on the holding ball display unit 10 c of the symbol display device 10. The RAM 23 is backed up by a backup power source so that the memory is retained even in the event of a power failure.

  Further, the main control unit 20 is provided with a random number generator 25 (for example, a random number counter that repeatedly generates random numbers within a predetermined range) for performing a big hit lottery. When a game ball wins the start winning opening 13 during the game, the CPU 21 operates the sampling circuit from the random number generator 25 to acquire the random number at that time. Then, with respect to the random number, a lottery lottery is performed with reference to a random number table stored in the ROM 22 in advance, and symbol variation is started in the symbol display device 10. If there are more winning balls during symbol change, 1 is added to the holding counter to hold the winning ball, the holding display on the holding ball display unit 10c is increased by 1, and a maximum of 4 holding balls are held and stored. To do.

  Further, the CPU 21 of the main control unit 20 outputs a symbol variation command to the symbol control unit 30, the voice control unit 40, and the lamp control unit 50 based on the lottery result of the big hit lottery. The symbol control unit 30, the voice control unit 40, and the lamp control unit 50 that have input these symbol variation commands select and determine various presentation programs such as reach, reach notice, miss, and jackpot stored in advance. Configured as follows.

  Further, when the game ball passes through the passing gate 4 in the state of the high probability mode, the CPU 21 of the main control unit 20 issues a command for notifying the high probability mode in order to notify the player of the high probability mode state. Output to the lamp controller 50 and the voice controller 40. Further, as described above, the main control unit 20 drives the small lamp group of the probability mode auxiliary display device 28 to be repeatedly turned on, blinked, or turned off according to the normal probability mode or the high probability mode.

  Similar to the main control unit 20, the voice control unit 40 includes a CPU unit as a main unit, and the CPU 41 performs various operations from the speaker 45 according to the progress of the pachinko game based on a program stored in the ROM 42 in advance. Generate sound. When a start condition such as when winning at the start winning opening 13 is established, an effect program is determined based on a symbol variation command sent from the main control unit 20, and data for generating sound corresponding to the effect program is generated. Read from the ROM 42 and generate sound from the speaker 45. Further, the voice control unit 40 operates to generate a voice such as a fanfare from the speaker 45 in response to the high probability mode notification command sent from the main control unit 20 when the high probability mode is notified.

  The lamp control unit 50 is configured with a CPU unit as a main part, similar to the main control unit 20, and the CPU 51 is arranged on the side of the front of the gaming machine according to the progress of the pachinko game based on the program stored in the ROM 52 in advance. Decorative lamps 56 to 58 such as lamps are turned on or blinked. When a start condition such as when winning at the start winning opening 13 is established, an effect program is determined based on the symbol variation command sent from the main control unit 20, data corresponding to the effect program is read from the ROM 52, and the data Based on the above, the decoration lamps 56 to 58 such as side lamps are turned on or blinked. In addition, the lamp control unit 50 turns on and blinks the lamps 56 to 58 in accordance with the high probability mode notification command sent from the main control unit 20 so as to notify the player that it is in the high probability mode. Operate.

  Next, the operation of the pachinko gaming machine having the above configuration will be described with reference to the flowchart of FIG.

  During the pachinko game, the normal probability mode is maintained in a normal state that is not a big hit state. Accordingly, the probability mode auxiliary display device 28 displays the normal probability mode in a state in which the small lamp group is turned on, blinking, or turned off by the main control unit 20 and hardly recognized by the player, and the lamps 56 to 58 are displayed. The high probability notification means does not perform the notification operation. Then, in a state where the game ball launched on the game board 3 does not pass through the passing gate 4 and does not enter the start winning opening 13, step 100 and step 160 in the flowchart of FIG. 3 are repeated.

  On the other hand, when the game ball launched on the game board 3 does not pass through the passing gate 4 and wins the start winning opening 13, the start winning opening detector 14 detects the ball and the start winning is detected by the CPU 21. The At this time, the CPU 21 determines in step 160 that it is a start winning prize, obtains a random number from the random number generator 25, performs a big hit lottery, and causes the symbol display device 10 to flow three rows of symbols from top to bottom. Starts variable display of symbols.

  And it progresses to step 170 from step 160, and it is determined whether the mode at that time is high probability mode. At this point, since the normal probability mode is selected, the process proceeds to step 190, where the lottery is performed with the normal probability, and the big hit lottery is performed with reference to the random number acquired from the random number generator 25 and the data table for the normal probability lottery. In step 200, the symbol display on the symbol display device 10 is stopped according to the lottery result.

  Here, when the acquired random number is not a big hit random number but a lost random number, the variable symbol of the symbol display device 10 is controlled to stop at the lost symbol. Then, in step 210, it is determined whether or not the stop symbol is a big hit symbol. If the symbol is not a big hit symbol, the process returns to step 100, and the steps 100 and 160 are repeated.

  On the other hand, when the game ball passes through the passing gate 4 and is detected by the gate detector 4a, the CPU 21 proceeds from step 100 to step 110, and determines whether or not the mode at that time is the high probability mode. Here, since it is the normal probability mode, the process proceeds from step 110 to step 130, where the display of the normal symbol display 27 is variably displayed and controlled to stop after a predetermined time. Then, in the next step 140, it is determined whether or not the symbol (number) stopped by the normal symbol indicator 27 is a predetermined predetermined symbol (number), and the stopped symbol is a lost symbol. If so, the process returns to step 100 and the above process is repeated. On the other hand, if the stop symbol is a winning symbol, the process proceeds from step 140 to step 150, where the start winning port solenoid 13b is operated to control the blade 13c of the starting winning port 13 to be opened for a predetermined time. As a result, it becomes easy for a game ball to enter the start winning opening 13.

  Here, when the game ball wins the start winning opening 13, as in the above, the CPU 21 of the main control unit 20 determines that the start win is received in step 160, acquires a random number from the random number generator 25, and performs a big hit lottery. At the same time, the variable display of the symbols is started so that the symbols on the symbol display device 10 flow from the top to the bottom in the three columns. And it progresses to step 170 from step 160, and it is determined whether the mode at that time is high probability mode. At this point, since the normal probability mode is selected, the process proceeds to step 190, where the lottery is performed with the normal probability, and the big hit lottery is performed with reference to the random number acquired from the random number generator 25 and the data table for the normal probability lottery. In step 200, the symbol display on the symbol display device 10 is stopped according to the lottery result.

  Here, when the lottery result is a big hit and the display symbols of the symbol display device 10 are stopped in line with the symbols corresponding to the big hit random numbers, it is determined that the big hit is made in the next step 210, and in the next step 220, A big hit operation is performed. When a big hit occurs, a big hit command is output from the main control unit 20 to the symbol control unit 30, the voice control unit 40, and the lamp control unit 50, and a big hit effect is performed, and the opening / closing member 11 a of the variable winning device 11. Is opened for a predetermined time, and the number of game balls won during that time is counted. When the number of winning balls reaches, for example, nine, the opening / closing member 11a is temporarily closed and one round is completed. In the meantime, when a game ball wins a continuous winning opening, the process proceeds to the next round, and the opening operation of the opening / closing member 11a is repeated for a predetermined time, and this is continued for a maximum of 16 rounds, for example.

  Next, in step 230, it is determined whether the current jackpot is a normal jackpot or a jackpot with a probability variation that increases the winning probability at the next jackpot lottery. At this time, the jackpot random number acquired at the time of winning the start is a jackpot random number with probability variation, and when the variation symbol stops in line with a predetermined odd number symbol such as “777”, for example, it is a jackpot with probability variation Then, go to step 240. In step 240, the flag for the high probability mode is set, and the mode of the gaming machine is set to the high probability mode. On the other hand, if the big hit random number is a normal big hit random number and stops in line with the normal symbol of “222”, for example, it is determined that it is a normal big hit, and then the routine proceeds to step 250 where the normal probability Mode (maintenance).

  As described above, the main control unit 20 controls lighting and blinking of the small lamp group of the probability mode auxiliary display device 28 according to the normal probability mode and the high probability mode. In an unrecognizable manner, the normal probability mode and the high probability mode are supplementarily displayed separately from the probability mode auxiliary display device 28.

  Then, after step 240 or 250, the process returns to step 100 again and the pachinko game is continued. For example, even if the mode of the gaming machine is changed to the high probability mode through step 240 as described above, the game ball If the player does not pass through the passing gate 4, the process proceeds from step 100 to step 160, and the high probability mode is displayed in a manner that cannot be easily recognized by the probability mode auxiliary display device 28, and is clearly notified to the player. Not. Therefore, it is unknown to the player whether or not the gaming machine has entered the high probability mode at this time.

  On the other hand, when the game ball passes through the passing gate 4 in the state of such a high probability mode, the process proceeds from step 100 to step 110, where it is determined that the mode of the gaming machine is the high probability mode, Proceeding to step 120, the high probability mode is notified. For the notification of the high probability mode, a command for notifying the high probability mode is output from the main control unit 20 to the lamp control unit 50, and the lamp control unit 50 turns on decorative lamps 56 to 58 such as lamps and side lamps. Controls blinking and is performed gorgeously. Therefore, the player knows that the gaming machine has entered the high probability mode at this point. It is also effective to output a high probability mode notification command to the voice control unit 40 to generate a fanfare or the like from the speaker 45 and notify the high probability mode by voice.

  Thereafter, in the same manner as described above, the process proceeds from step 120 to steps 130 to 160. When the symbol on the normal symbol display 27 fluctuates at a high speed and stops, and the predetermined symbol stops, the start winning opening 13 is set to the predetermined value. Opened for hours. Therefore, when the game ball wins the start winning opening 13, the process proceeds from step 170 to step 180, where a high probability lottery with a high probability of winning the jackpot is performed, and the random number acquired from the random number generator 25 is A big hit lottery is performed with reference to the data table for high probability. Then, when the lottery result is a big hit and the variable symbols of the symbol display device 10 are stopped in line with a predetermined big hit symbol, a big hit is generated, and a big hit operation is performed in step 220 as described above. When the big hit is a normal big hit, the process proceeds from step 230 to step 250, and the mode of the gaming machine is shifted from the high probability mode to the normal probability mode. When the normal probability mode is entered, the big win lottery at the time of starting winning is performed with the normal winning probability instead of the high probability, and of course, the high probability mode state is not notified.

  Thus, when the game ball passes through the passing gate 4, if it is in the high probability mode, it is notified to the player by lighting or blinking the lamps 56 to 58 or generating sound from the speaker 45. Therefore, the player recognizes the transition to the high probability mode, that is, the transition to the probability fluctuation state, and thereafter, the player can enjoy the game with a great expectation of jackpot. In addition, since the high probability mode is notified for the first time when a game ball passes the passing gate, the passing of the game ball to a specific gate is meaningful, and the player aims at the specific gate. As a result, the game characteristics of the pachinko game can be further improved. Furthermore, regardless of the normal probability mode or the high probability mode, if the game ball does not pass through the passing gate 4, the high probability mode state is not notified, so that the player expects until the game ball passes through the passing gate 4. The game can be played with a feeling.

  In addition to the passing gate 4, a gate disposed in a normal electric accessory or a warp route can be used as a specific gate that triggers notification of the high probability mode.

  In the above embodiment, when the game ball passes through the passing gate 4, the high probability mode is always notified in the case of the high probability mode. However, when the game ball passes through the passing gate, the notification lottery means (random number) A random number is acquired from a generator, and when a specific random number is acquired, a lottery is performed by means of winning), and only when the notification lottery is received, the high probability mode is notified when the game ball passes through the gate It can also be configured. In this case, even if the mode is shifted to the high probability mode, if the notification lottery is not met, the notification is not made. Therefore, even if the notification is not made, the high probability mode is notified when the next gate passes. Can make people expect.

  In addition, a counter for counting the number of game balls that have passed through the passing gate 4 is provided, and when the value of the counter for counting the number of passing gates reaches a predetermined number, the high probability mode is notified in the case of the high probability mode. It can also be configured. Even in this case, even if the mode is shifted to the high probability mode, the notification is not made until the number of gate passes reaches a predetermined number. It can be expected that the player may be.
