Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is such that when a start condition is satisfied, a symbol is variably displayed on a symbol variable display such as a liquid crystal display, and when it is stopped by a certain symbol with a certain probability by chance, it becomes a big hit state. The present invention relates to a gaming machine such as a pachinko machine that enables the player to obtain a gaming ball.

[0002]

2. Description of the Related Art As is well known, a so-called type 1 pachinko gaming machine is provided with a color liquid crystal display, a pattern variation display such as a CRT, etc. on a game board surface, and a hit ball hit by a player is a tulip type starting port. When entering, 1 to 8 on the symbol variation display
The numbers and symbols such as ☆ ◆ ◎ or symbols such as characters are displayed in multiple rows (usually three rows) so that they flow vertically or horizontally, and the display changes are stopped in sequence after a few seconds and then stopped. For example, "222", "777", with a certain probability that the symbol has a predetermined probability (about 1/300),
When it becomes a predetermined design such as "☆☆☆", it becomes a big hit state, and the variable winning device (big winning opening)
The open / close door is opened by the operation of the solenoid, and a predetermined number of ball hits (usually 1
(0) Enter the ball, or if a predetermined time limit (usually 30 seconds) elapses in the open state, the so-called first round is over and the variable winning device is temporarily closed, but during the first round, the variable winning device is changed. When the continuous winning opening (referred to as the V zone) provided in the winning device is hit, the variable winning device is opened again immediately after the second round starts, and the open state is established. When a predetermined number of ball hits (usually 10) is entered into the variable winning device or the predetermined time limit (usually 30 seconds) elapses in the open state, the second round ends and the variable winning device is Close again, but the second
If there is a hit ball in the continuous prize hole during the round, the variable winning device is opened again immediately after the third round starts, and the condition is that the hit ball has been won in the continuous prize hole during each round. The variable winning device is continuously opened until the final round (for example, the 16th round),
Since it is possible to obtain a large number of prize balls in such a big hit state, the player is provided with many benefits.

Also, in this type of gaming machine, "333"
When a big hit with an odd number of symbols such as "555" and "777" (hereinafter referred to as "specific symbol"), the probability of the next big hit occurrence after the end of the big hit state is, for example, 1/300 to 1/60 of the normal. (It is called "probability change" in the industry), or the opening time of the tulip-shaped opening is extended from the normal 0.5 seconds to 2 seconds (which is called "time saving" in the industry). A condition that is advantageous to the player even after the jackpot state has ended (hereinafter,
Known as "privilege").

[0004]

By the way, the above-mentioned privilege is
In the past, it was started uniformly immediately after the jackpot state ended, so if you did not hit the jackpot due to the specific symbol as described above, the bonus was not awarded and the jackpot state ended. Since the player's expectation has to be greatly reduced later, there has been a problem that this game itself is easily stopped. The present invention is intended to solve such problems and to provide a gaming machine which can always play with a sense of expectation and which can keep the player sufficiently interested.

[0005]

[Means for Solving the Problems] Therefore, according to the present invention, the display symbol of the symbol variable indicator fluctuates when the starting condition is satisfied, and when a predetermined predetermined symbol is stopped, a big hit state is set and a large number of game balls. In the gaming machine capable of acquiring, a privilege advantageous to the player when a predetermined condition is satisfied is generated during a predetermined period after the jackpot state ends. Further, the present invention, in the pachinko gaming machine, lottery related to the privilege mode is carried out by being in the big hit state, and after the big hit state is finished, the lottery result is changed after the display symbol of the symbol variation display is changed a predetermined number of times. According to the above, the privilege is generated. Further, the present invention, the display symbol of the symbol variation display fluctuates due to the satisfaction of the starting condition, and when stopped at a predetermined predetermined symbol, it becomes a jackpot state and it is possible to obtain a large number of game balls. A lottery related to a privilege mode that is advantageous to the player is performed, and the probability that a privilege is generated by the lottery is set to be high for a predetermined period after the jackpot state ends. Further, the present invention, the display symbol of the symbol variation display fluctuates due to the satisfaction of the starting condition, and when stopped at a predetermined predetermined symbol, it becomes a jackpot state and it is possible to obtain a large number of game balls. A lottery related to a privilege mode that is advantageous to the player is performed, and the privilege generated by the lottery is set to be more advantageous to the player than usual during a predetermined period after the jackpot state ends. And Further, the present invention is characterized in that, in the above-mentioned pachinko gaming machine, the privilege increases the probability of occurrence of a jackpot state. Further, the present invention is characterized in that, in the pachinko gaming machine, the privilege is to extend the opening time of the tulip-shaped starting opening.

In addition, 10 is provided in order to store the number of hit balls in the starting port 5 during the variable display of the variable display 2 and to hold the start 4
Two holding display lamps, 11 is a normal symbol fluctuation display device (7-segment digital display device) that starts changing when the hit ball passes through the passing gate 4, 12 is a passing gate 4 while the normal pattern fluctuation display device 11 is displaying fluctuations. When the number of hit balls has passed, four holding display lamps are provided to store the number of balls and hold the variable display, and 13 is a decoration lamp.

FIG. 2 is a block diagram showing an input / output device related to the present invention, which is connected to a control board 15 composed of a CPU, a ROM, a RAM, and an I / O. Reference numeral 20 denotes a ball hit by the passage gate 4. A passage detection switch, 21 is a start switch for detecting a hit ball that has won in the starting opening 5, 22 is a count switch for counting the winning balls to the variable winning device 7, 23 is a winning ball to the continuous winning opening 9 It is a specific area switch, and on the game control board, the symbol variation display 2, the hold display lamps 10 and 12, the normal symbol variation display 11, the decoration lamp 13, and the solenoid 25 of the variable winning device 7 are provided. And a solenoid 26 for opening and closing the blade of the starting port 5 is connected.

Next, the features of the invention described in claims 1, 2 and 5 will be described with reference to the flowchart of FIG. When the starting condition is satisfied by detecting the winning of the game ball into the starting opening 5 by the starting switch 21 in step a, the fluctuation of the display symbol of the symbol fluctuation indicator 2 is started in step b, and in step c. It is determined whether or not the bonus is being given. If the bonus is being given, in step d, the probability of the jackpot is high (for example, 1/3).
0), and when the privilege is not being given, the probability of jackpot occurrence is set to a low probability (for example, 1/300) in step e. Then, in step f, various symbol stop patterns such as reach mode are selected and displayed on the symbol variation display 2, and in step g, all symbols are stopped.

Then, at step h, the stop symbol is "2.
22 "," 777 "," ☆☆☆ ", etc. is determined whether or not it is a predetermined symbol, and if it is a predetermined symbol, the process moves to step i, and the symbol variation display 2 displays" big hit "and a big hit. As a result, the opening / closing door 8 of the variable winning device 7 can be continuously opened for several rounds depending on the progress, and a large number of prize balls can be acquired. Then, when this jackpot state ends, lottery related to the privilege mode is performed in step j. This lottery is for determining the presence / absence of a privilege and the content of the privilege, and is determined in any of the four privilege modes A to D as shown in Table 1, for example.

[Table 1]

[0010] In privilege mode A, this jackpot state ends and a game ball is newly won in the starting opening 5 to change the symbol display 2
When the number of times the display symbol fluctuates reaches 70 times (synonymous with 70 consecutive losses), the jackpot occurrence probability is increased from the usual low probability (1/300) to high probability (1/30). , The high probability state until the number of times the display symbol of the symbol variation display 2 fluctuates further 30 times (the gap is further 3
It is continued until it continues 0 times), and then the content is to return to the normal low probability.

In the privilege mode B, the jackpot occurrence probability is changed from low probability (1/300) to high when the number of times the display symbol of the symbol variation display device 2 has changed 50 times after the jackpot state is finished. The probability (1/30) is increased, and the high probability state is continued until the number of times the display symbol of the symbol variation display 2 fluctuates further 50 times, and thereafter the content returns to a normal low probability. . Also, privilege mode C
After the jackpot state ends and the display symbol of the symbol variation display 2 fluctuates once, the jackpot occurrence probability is set to a low probability (1/3).
00) to a high probability (1/30), the high probability state continues until the number of times the display symbol on the symbol variation display 2 changes 99 times, and then returns to the normal low probability. To do. Further, in the privilege mode D, even after the jackpot state is over, the probability of the jackpot is kept at a normal low probability, and the bonus is not substantially given. Then, the lottery results such as the required number of fluctuations H until the privilege is generated and the number T of privilege grants are stored in the memory in step k.

When it is determined in step h that the stop symbol is not the predetermined symbol, the process goes to step l without a big hit state and it is determined whether or not the privilege is being given. If the privilege is being given, In step m, 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 process directly returns to step a. If it is zero, the process goes to step o. After the memory of the lottery result is reset, the process returns to step a.

If it is determined in step l that the privilege is not being granted, the process proceeds to step p, where 1 is subtracted from the required number of changes H, and whether the required number of changes H is not zero in step q. Is discriminated, and if it is not zero, the process directly returns to step a, and if it is zero, step r
The privilege is given at and the process returns to step a.

The process of the lottery in the above 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 held privately inside the machine.

Further, by displaying the required number of times of variation H on the symbol variation display 2 or the like and displaying the period until the benefit is awarded to the player, the enjoyment of continuing the game is given to the player. By doing so, you can make an appeal so as not to stop this game on the way.

In addition to the example of the privilege mode shown in Table 1 above, as shown in Table 2, the number of fluctuations H is 99 times or 50 times or once, and the privilege grant number T is 100 times. Various settings can be made.

[Table 2] In this case, by not displaying the period until the award is granted, it is expected that the award will be generated each time there is a change in the design, so the expectation is rather maintained and the player is entertained. There is also. In addition, it is possible to display that there is a possibility of granting the privilege up to the maximum number of times of change in which the privilege may be granted regardless of which mode is selected, including a mode in which the privilege is not granted.

In addition, the privilege contents increase the probability of occurrence of a big hit state as described above, and extend the opening time of the blades of the starting opening 5 more than usual to increase the chance of symbol variation. There may be various forms such as, shortening the variation time of the display symbol of the symbol variation display, or combining these benefits. In addition, as for the condition for ending the privilege granting condition, the number of symbol fluctuations is set to a predetermined number as described above, until the next big hit occurs, or a predetermined reach mode or the like is given to the symbol fluctuation display. Various settings are possible, such as until the symbol stop pattern is displayed, or the number of times the starting opening 5 is opened after a time extension is reached a predetermined number of times.

In the above embodiment, the lottery is performed when the jackpot state is over, but as in the case where the stop symbols of the symbol variation display 2 are arranged in odd numbers such as "333" and "777", When a big hit occurs in a specific symbol, it is possible to trust that the above-mentioned privilege is generated in a predetermined period after the end of the big hit state.

On the other hand, FIG. 4 is a flow chart showing the features of the invention described in claims 3, 4, and 5. In this embodiment, the starting condition is satisfied in step (1), the variation of the symbol displayed on the symbol variation display device 2 is started in step (2), and the privilege grant count T is 1 or more in step (3). It is determined whether or not it is 1 or more times, and if it is 1 or more, it is 1 from the privilege number T
After subtracting, the probability of jackpot occurrence is set to a high probability (1/30) in step (5), and the number of times T of granting privilege is 1
If it is not equal to or more than the number of times, in step (6) the jackpot occurrence probability is set to a low probability (1/300). Then, in step (7), various symbol stop patterns such as the reach mode are selected and displayed on the symbol variation display 2, and in step (8) all symbols are stopped.

Then, in step (9), it is determined whether or not the stopped design is a predetermined design, and if it is the predetermined design, the process proceeds to step (10) to generate a jackpot state. When the jackpot state ends, the privilege state is initialized in step (11), and the special period K is set to 100 times in step (12).
Return to step (1).

If it is determined in step (9) that the stop symbol is not the predetermined symbol, the process goes to step (13) without a big hit state, and whether the special period K is one or more times. If it is determined that the number is one or more, the special period K is decremented by 1 in step (14), and then a lottery is performed in step (15) as to whether or not to grant the privilege. Step (16). In this lottery, the probability that the privilege will be granted is set to a high probability (1/100), and when it comes to a hit, the privilege grant count T is set to 100 in step (17). Then, the process returns to step (1). Also,
If it is determined in step (13) that the special period K has never occurred, the process proceeds to step (18) and a lottery is performed to determine whether or not to grant a privilege. Is set to a low probability (1/1000). If the lottery results in a hit, the privilege number T is set to 30 in step (20), and the process returns to step (1).

Therefore, in this embodiment, until the number of symbol variations after the jackpot state reaches 100 times, the probability that the privilege is given every time the symbol varies during the special period changes with a high probability, and The benefits are large when it becomes atari (the privilege grant count T = 100), but if it is 100 times or more, the probability that the privilege is granted outside the special period becomes low, and at the same time, it becomes atari. Is small (the number of times of grant T = 30).

As determined in step (3) above, this privilege is to set the probability of the jackpot state occurrence to a high probability setting or a low probability setting, so that more benefits are acquired. If it is done, it will be advantageous to the player.

FIG. 5 shows the transition of the jackpot occurrence probability that can be assumed in the gaming machine shown in this embodiment.
Then, when the initial jackpot occurrence probability was 1/300 of the normal one, it was attrited in the privilege granting lottery in the above step (18), and thereafter the jackpot occurrence probability became 1/30 until the number of symbol fluctuations reached 30 times, An example in which the jackpot occurrence probability returns to 1/300 of the normal value if the period elapses without the jackpot being generated. Further, (B), when the jackpot occurrence probability is 1/300 of the normal one, when the jackpot occurs and the jackpot state ends, the step (13) shifts to the step (15). There is a high probability that a special lottery will be given as a special period until 100 times (1/100)
Here is an example. In this case, there is no change in the jackpot occurrence probability. In addition, in (c), when the lottery for granting a privilege has a high probability (1/100), the chance of being hit by the lottery causes the jackpot occurrence probability to be 1/300 to 1 / normal.
The high probability state rises to 30, indicating that the number of symbol fluctuations is up to 100 times.

As described above, in the gaming machine of the present invention, even after the jackpot state is finished, the privilege is not uniformly given as in the conventional case, and the mode is diverse, so that it is always sufficient as a player. You can continue playing with great expectations and interests. Although this embodiment has been described for a pachinko gaming machine, the present invention can 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.

[0026]

As described above, according to the present invention, the display symbol of the symbol variable indicator fluctuates when the starting condition is satisfied, and when a predetermined predetermined symbol is stopped, the jackpot state is set and a large number of game balls can be obtained. In the gaming machine,
When the predetermined condition is satisfied, the privilege advantageous to the player is generated during the predetermined period after the jackpot state is finished, so that the player can always play with expectation,
It has the effect of increasing interest.
