Description

  According to the present invention, when the start condition is satisfied, the symbol is displayed in a variable manner on a symbol variation display such as a liquid crystal display, and when it stops at a certain symbol with a certain probability by chance, it becomes a big hit state and a large number of game balls can be acquired It relates to a gaming machine such as a pachinko machine.

  As is well known, the so-called first type pachinko gaming machine is provided with a pattern variation display such as a color liquid crystal display, CRT, etc. on the game board surface, and when the hit ball hit by the player enters the tulip-shaped start opening, The symbols 1 to 8 and symbols such as ☆ ◆ ◎ or characters etc. are displayed on the design variation display in multiple rows (usually 3 rows) so that the symbols flow up and down or left and right respectively. When it stops in a few seconds, and the stop pattern becomes a predetermined pattern such as “222”, “777”, “☆☆☆” with a certain probability (about 1/300) by chance. When the jackpot state is reached, the open / close door of the variable winning device (large winning port) is opened by the operation of the solenoid, and a predetermined number (usually 10) of hit balls enter the variable winning device in the opened state, or Open state When the predetermined time limit (usually 30 seconds) elapses, the so-called first round is over and the variable prize-winning device is temporarily closed. During this first round, the continuous prize opening provided in the variable prize-winning device ( When a hit ball has entered the V zone), the variable winning device is opened again as soon as the second round begins, and a predetermined number of hit balls (in the opened variable winning device) ( (Usually 10), or when the predetermined time limit (usually 30 seconds) has elapsed in the open state, the second round is over and the variable prize-winning device is closed again, but continues during the second round If a ball hits the winning hole, the third round starts and the variable winning device is opened again, and the final round (for example, on the condition that the ball hits the continuous winning hole during each round (for example, 16th The variable winning device until und) is continuously open, which is constituted such that many benefits provided to the player because it can obtain a large number of prize balls when a such a jackpot status.

  In addition, in this type of gaming machine, when a big hit is made with an odd number of symbols such as “333”, “555”, and “777” (hereinafter referred to as “specific symbols”), For example, the probability is increased from 1/300 to 1/60 (in the industry, referred to as “probability”), or the opening time of the tulip starter is extended from normal 0.5 seconds to 2 seconds ( (In the industry, it is referred to as “short time”), and it is possible to give a privilege such as making it easier to establish the start condition, and there is a situation that is advantageous to the player (hereinafter referred to as “the privilege”) even after the big hit state is over What is going on is known.

By the way, since the above-mentioned benefits were conventionally started immediately after the jackpot state ended, if the bonuses were not hit by the specific symbols as described above, the benefits are not granted, Since the player's sense of expectation must be greatly reduced after the big hit state is over, there is a problem that the game itself is likely to be stopped.
The present invention is intended to solve such problems and to provide a gaming machine that can always be played with a sense of expectation and that can continue to give a sufficient interest to the player.

Therefore, the present invention provides a gaming machine in which the display symbol of the symbol variation indicator fluctuates when the starting condition is satisfied, and when it stops at a predetermined symbol, it becomes a big hit state and a large number of game balls can be obtained. Further, when a predetermined condition is satisfied, a privilege advantageous to the player is generated in a predetermined period after the jackpot state is ended.
In addition, in the pachinko gaming machine described above, a lottery regarding the privilege mode is performed when the jackpot state is reached, and after the jackpot state ends, the lottery result after the display symbol of the symbol variation indicator fluctuates a predetermined number of times. According to the present invention, the privilege is generated.
Further, the present invention is a gaming machine in which the display symbol of the symbol variation indicator fluctuates when the starting condition is satisfied, and when it stops at a predetermined symbol that is predetermined, it becomes a big hit state and a large number of game balls can be acquired. A lottery regarding a privilege mode advantageous to the player is performed, and a probability that a privilege is generated by the lottery is set high for a predetermined period after the big hit state is ended.
Further, the present invention is a gaming machine in which the display symbol of the symbol variation indicator fluctuates when the starting condition is satisfied, and when it stops at a predetermined symbol that is predetermined, it becomes a big hit state and a large number of game balls can be acquired. The lottery regarding the privilege mode advantageous to the player is performed, and the privilege generated by the lottery is set to be more advantageous than usual for the player for a predetermined period after the big hit state is ended. And
The present invention is characterized in that, in the pachinko gaming machine described above, the privilege increases the probability of occurrence of a jackpot state.
Further, the present invention is characterized in that in the pachinko gaming machine described above, the privilege extends the opening time of the tulip-shaped start port.

  Thus, according to the present invention, when the start condition is satisfied, the display symbol of the symbol variation indicator fluctuates, and when stopped at a predetermined symbol, a gaming machine is obtained in which a big hit state is obtained and a large number of game balls can be obtained. In this case, when a predetermined condition is satisfied, a privilege advantageous to the player is generated in a predetermined period after the jackpot state ends, so that the player can always play with a sense of expectation and an effect of increasing interest is there.

  Next, an embodiment of the invention will be described for a pachinko gaming machine. FIG. 1 shows a front view of a game board 1 of a pachinko gaming machine. In the figure, 2 is a symbol variation display device composed of a color liquid crystal display provided on the game board 1, 3 is a normal winning opening, and 4 is a pass gate. Reference numeral 5 denotes a tulip-shaped start port provided so that a pair of blades can be opened and closed by a solenoid, and reference numeral 6 denotes an upper winning prize opening. Reference numeral 7 denotes a variable winning device comprising a large rectangular large winning opening provided below the start opening 5. The variable winning device 7 is provided with an opening / closing door 8 that is opened and closed by the operation of a solenoid. A continuous winning opening 9 is provided in the device 7. Reference numeral 10 denotes four holding display lamps provided for storing the number of hitting balls when the symbol variation indicator 2 displays the variation while the starting variation 5 is displayed and holding the starting, and 11 for hitting the passing gate 4. The normal symbol variation display (7-segment digital display device) 12 starts to change when the ball passes, and the number 12 stores the number of hit balls when the normal symbol variation indicator 11 passes through the passing gate 4 while the variation is being displayed. Four on-hold display lamps 13 are provided for holding the variable display, and 13 is a decorative lamp.

  FIG. 2 is a block diagram showing an input / output device related to the present invention connected to a control board 15 comprising a CPU, ROM, RAM, and I / O. A switch, 21 is a start switch that detects a hit ball that has won a winning opening 5, 22 is a count switch that counts the winning balls to the variable winning device 7, and 23 is a specific area that detects a winning ball to the continuous winning opening 9 The game control board further includes the symbol variation indicator 2, the hold indication lamps 10, 12, the normal symbol variation indicator 11, the decoration lamp 13, the solenoid 25 of the variable winning device 7, and the start. A solenoid 26 that opens and closes the blades of the mouth 5 is connected.

  Next, the features of the present invention will be described with reference to the flowchart of FIG. When the start condition is established by detecting the winning of the game ball to the start port 5 by the start switch 21 in step a, the change of the display symbol of the symbol variation display 2 is started in step b, and in step c. It is determined whether or not a privilege is being granted. If the privilege is being granted, the probability of jackpot is set to a high probability (for example, 1/30) in step d, and if the privilege is not being granted in step e. The jackpot occurrence probability is set to a low probability (for example, 1/300). In step f, various symbol stop patterns such as the reach mode are selected and displayed on the symbol fluctuation display 2. In step g, all symbols are stopped.

Then, in step h, it is determined whether or not the stop symbol is a predetermined symbol such as “222”, “777”, “☆☆☆”, etc., and if it is the predetermined symbol, the process proceeds to step i and the symbol variation display is performed. By displaying “big hit” on the device 2 and being in the big win state, the open / close door 8 of the variable winning device 7 is continuously opened until several rounds as it progresses, and a large number of prize balls can be acquired. Then, when the jackpot state is finished, a lottery regarding the privilege mode is performed in step j. This lottery is for determining whether or not a privilege is generated and the details of the privilege. For example, the lottery is determined as one of four privilege modes A to D as shown in Table 1.

  In the privilege mode A, when the big hit state is finished and the game ball is newly won at the starting port 5 and the number of times the display symbol on the symbol variation display 2 has changed 70 times (when the loss continues 70 times) The probability of jackpot occurrence is increased from the normal low probability (1/300) to the high probability (1/30), and the high probability state is further increased by 30 times in the design variation display 2 (Synonymous with lasting 30 misses) and then returning to the normal low probability.

  Also, in the privilege mode B, the probability of jackpot occurrence is reduced from a low probability (1/300) to a high probability (1) when the number of fluctuations of the display symbol on the symbol fluctuation display 2 after the jackpot state ends is 50 times. / 30), the high probability state continues until the number of times of change of the display symbol of the symbol variation indicator 2 reaches 50 times, and thereafter returns to the normal low probability. In addition, the bonus mode C increases the probability of jackpot occurrence from a low probability (1/300) to a high probability (1/30) after the jackpot state ends and the display symbol of the symbol variation indicator 2 fluctuates once. The high-probability state continues until the number of times of change of the display symbol of the symbol variation indicator 2 reaches 99, and thereafter returns to the normal low probability. Further, in the privilege mode D, even after the jackpot state ends, the probability of jackpot occurrence remains at a normal low probability, and no privilege is granted. The lottery results such as the required fluctuation count H and the bonus grant count T until the bonus is generated are stored in the memory at step k.

  If it is determined in step h that the stop symbol is not a predetermined symbol, it is determined whether or not a privilege is being given by shifting to step l without becoming a big hit state. 1 is subtracted from the privilege grant count T, and it is determined in step n whether the new privilege grant count T is not zero. If it is not zero, the procedure returns to step a. After the result storage is reset, the process returns to step a.

  If it is determined in step l that no privilege is being granted, the process proceeds to step p, where 1 is subtracted from the required variation count H, and in step q it is determined whether the required variation count H is not zero. If it is not zero, the process returns to step a as it is, and if it is zero, a privilege is granted in step r and the process returns to step a.

  The lottery process in step j may be disclosed to the player by displaying a game such as roulette on the symbol variation display 2, or the lottery may be performed privately inside the machine. It may be.

  In addition, by displaying the required variation number H on the symbol variation display 2 and the like, and displaying the period until the privilege is given to the player, the player can enjoy the game, It is possible to appeal so that this game is not stopped on the way.

In addition to those exemplified in Table 1 above, the privilege mode has various settings such as, as shown in Table 2, the number of fluctuations H is 99, 50, or 1 and the privilege grant count T is 100. Can do.
In this case, by not displaying the period until the bonus is granted, it is expected that the bonus will be generated every time there is a change in the design, so the expectation will be maintained and the player will be entertained. There is also.
Further, it may be displayed that there is a possibility of giving a privilege up to the maximum number of times that the privilege can be given regardless of which mode is selected including a mode in which the privilege is not given.

  In addition to increasing the probability of occurrence of the jackpot state as described above, the privilege content can be increased by increasing the opening time of the blades of the starting port 5 to be more normal than usual. There can be various forms such as shortening the fluctuation time of the display symbol of the symbol variation indicator, or using these benefits together. In addition, as for the condition for the privilege granting state to end, as described above, the number of symbol fluctuations will be a predetermined number of times, or until the next big hit occurs, or a predetermined reach mode such as a special reach mode on the symbol variation display Various settings can be made, for example, until the time when the symbol stop pattern is displayed or until the predetermined number of times the start port 5 is extended for a certain period of time.

  In the above embodiment, the lottery is performed when the big hit state is over, but the symbols of the symbol change display 2 are stopped by an odd number such as “333” and “777”. When a jackpot occurs, it can be trusted that the above-mentioned benefits are generated in a predetermined period after the end of the jackpot state.

  On the other hand, FIG. 4 is a flowchart showing the features of the inventions according to claims 1 to 4. In this embodiment, the starting condition is established in step (1), the change of the display symbol of the symbol fluctuation indicator 2 is started in step (2), and the privilege grant count T is 1 or more in step (3). And if it is 1 or more, after subtracting 1 from the number of privilege grant T in step (4), the probability of jackpot occurrence is high (1/30) in step (5) If the privilege grant count T is not 1 or more, the jackpot occurrence probability is set to a low probability (1/300) in step (6). In step (7), various symbol stop patterns such as the reach mode are selected and displayed on the symbol variation display 2. In step (8), all symbols are stopped.

  In step (9), it is determined whether or not the stop symbol is a predetermined symbol. If the symbol is a predetermined symbol, the process proceeds to step (10) to generate a big hit state. When the jackpot state ends, the privilege state is initialized in step (11), the special period K is set to 100 times in step (12), and the process returns to step (1).

  If it is determined in step (9) that the stop symbol is not a predetermined symbol, the process proceeds to step (13) without a big hit state, and it is determined whether or not the special period K is one or more times. If it is once or more, after subtracting 1 from the special period K in step (14), a lottery is performed in step (15) as to whether or not a privilege is granted. Step (16). In this lottery, the probability that a privilege is granted is set to a high probability (1/100), and when it becomes a hit, the privilege grant count T is set to 100 in step (17). And it returns to step (1). If it is determined in step (13) that there is no special period K, the process proceeds to step (18) and a lottery is performed as to whether or not a privilege is to be granted. Is set to a low probability (1/1000). Further, when the lottery is a hit, the privilege grant count T is set to 30 in step (20), and the process returns to step (1).

  For this reason, in this embodiment, until the number of symbol fluctuations after the end of the jackpot state reaches 100, it is a special period, and the probability that a privilege will be granted each time the symbol fluctuates changes with high probability. The benefits in the case of a bonus will be large (privilege grant count T = 100), but if it exceeds 100, the probability that a privilege will be granted outside the special period will be low, and the bonus will be It becomes smaller (privilege grant count T = 30).

  And, as determined by the above step (3), since this privilege is to set the probability of occurrence of jackpot state to a high probability setting or a low probability setting, if this privilege is acquired more It is advantageous for the player.

  FIG. 5 shows the transition of the jackpot occurrence probability that can be assumed in the gaming machine shown in this embodiment. In (A), when the initial jackpot occurrence probability is 1/300 of the normal, the above step (18) The bonus grant probability will be attrited and the jackpot occurrence probability will be 1/30 until the number of symbol fluctuations reaches 30 after that, and if the period passes without a jackpot occurrence, the jackpot occurrence probability is normal 1 An example of returning to / 300 is shown. In (b), when the jackpot occurs when the probability of jackpot occurrence is 1/300, and when the jackpot state ends, the process proceeds from step (13) to step (15). An example is shown in which a lottery for award grant is made with a high probability (1/100) as a special period until the number of times reaches 100. In this case, there is no change in the probability of jackpot occurrence. Also, in (c), when the lottery for granting a bonus has a high probability (1/100), the probability of jackpot rises from 1/300 to 1/30, which is a high probability state. Indicates that the number of symbol fluctuations is 100.

Thus, in the gaming machine of the present invention, even after the end of the jackpot state, the benefits are not uniformly given as in the past, and there are various aspects, so that the player always has a sufficient sense of expectation. You can continue playing with interest.
Although this embodiment has been described with respect to a pachinko gaming machine, the present invention can also be applied to a slot machine or the like. In that case, it goes without saying that a game medium such as a medal is used instead of the game ball.
