Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a pachinko game machine, and particularly to a pachinko game machine that is provided with a movable piece that is provided on the front surface of the game board and is isolated from the surrounding game area in a normal state, and that has two internal parts with different properties. The present invention is used in a pachinko game machine that has two winning areas and is equipped with a variable winning device in which the movable piece is triggered to rotate when a ball hits a specific winning opening provided in the gaming area. related to effective techniques.

[Prior art] Conventionally, pachinko machines have, for example, a pair of wing-shaped movable pieces and are placed approximately in the center of the game board in order to vary the game content and improve the service to players. A variable winning device is provided in which a movable piece reciprocates about 90 degrees when a ball hits a specific winning opening at the bottom of the game board.

This variable winning device has two types of winning areas, a special winning area and a general winning area, inside the movable piece, and the movable piece is triggered once by a winning in the special winning opening at the bottom of the game board. Or, if it is rotated about two times, the surroundings of the variable prize winning device and the internal space are communicated with each other, and it becomes possible for batted balls flowing down the gaming area to jump into the variable prize winning device. Then, when a batted ball that flies into the inside of the variable winning device accidentally enters the special winning area, the movable piece is rotated multiple times (for example, 18 times) in succession, and moreover, it is rotated multiple times (for example, 8 times). The cycle) can be repeated to generate a special benefit state of increasing the probability of the ball hitting the variable prize winning device.

[Problem] Conventionally, in this type of variable winning device, winning in the special winning area was only left to chance. Therefore, even when a special game state finally occurs after a long time of playing, the special game is repeated with the condition of continuing winning the special winning area again.
The chance factor was very strong, and special games often ended in one cycle. Therefore,
Even though a special game occurred, the number of balls paid was small and the game did not continue, resulting in players not feeling satisfied.

Moreover, the conventional variable prize winning device has 18 movable members.
If no batted ball enters the special winning area by the time the ball opens and closes twice or 10 batted balls win a prize, the special game is controlled to end at that point, and the movable member opens and closes about 7 to 8 times. There were times when the number of winning balls reached 10 just by repeating the game, and the special game ended. . Therefore, even if a special game occurs, the expected number of balls often cannot be obtained.

[Purpose of the invention] This invention is intended to solve the above-mentioned inconvenience, and its purpose is that when a special gaming state occurs due to winning in the special winning area, relatively many The goal is to ensure that the ball is awarded.

[Means for solving the problem] Therefore, the winning opening in the special winning area in the variable winning device is configured to be able to be expanded or contracted, and when the conditions set in advance in the electric control device are met, the winning opening in the special winning area is activated. By enlarging the mouth and making it easier for the winning batted ball to enter the special winning area, the chance of the special game being continued is increased, and thereby the special game is played under the conditions that are close to the best within the set conditions. This guarantees that a relatively large number of balls will be played by ensuring that the game is executed.

[Example] Fig. 1 shows an example of the configuration of a playing area of a pachinko game machine equipped with a variable prize winning device according to the present invention. A guide rail 3 is provided that guides a ball fired by a device (not shown) to the upper part of the game board 1.
A gaming area is defined in a space surrounded by a glass plate and a glass plate. A variable prize winning device 5 is provided in the center of this gaming area.

A first special winning hole 7a is provided below the variable winning device 5, and second special winning holes 7b and 7c are provided on both sides thereof. These special winning holes 7a to 7c are constituted by, for example, a winning tool called a winning chucker.

6c is integrally provided. Variable winning device 5
General prize winning holes 8 are placed on both sides of the hole, and below these, a tulip type batted ball winning device 9 is placed.

At the bottom of the game board 1, each winning area 6a to 6c, 7a to
An out port 10 is provided to collect the batted balls that do not win prizes such as 7c, 8, 9, etc. to the rear of the game board. Further, at appropriate positions on the surface of the game board 1, there are a number of obstacle nails 11 that randomly change the direction of the hit ball falling from above, and rolling guide members 12a to 12c that control the falling speed and direction of the hit ball. are provided almost symmetrically with respect to the vertical center line of the gaming area.

In FIGS. 2 and 3, the variable prize winning device 5
A first example is shown.

The above-mentioned three general winning holes 6a to 6c are provided on the upper part of the component board 50 of the variable winning device 5,
A decorative plate 51 is attached to cover the front of these general prize winning holes 6a to 6c. The general winning holes 6a to 6c are formed to protrude forward from the surface of the game board 1, but the component board 50 is attached so as to be substantially flush with the surface of the game board 1.

At the center of this component board 50, a pair of movable members 52a, which are shaped like a horse's head and tail, are installed.
52b are each rotatably mounted around a rotation shaft 53 as a fulcrum. Moreover, movable members 52a, 52
Below b, a pair of movable members 54a and 54b imitating the shape of a horse's legs are rotatably mounted around a rotation shaft 55 as a fulcrum. The rotation shaft 53 is attached to a bearing portion 50a fixed to the component board 50, and
The rotation shafts 55 are inserted into and supported by the bearing portions 50b, respectively.

The movable members 52a, 52b and 54a, 5
4b is rotated approximately 90 degrees outward by a drive source (not shown) such as a solenoid attached to the back of the component board 50, on the condition that a prize is won in the special prize openings 7a to 7c. surrounding play area,
The movable members 52a, 52b, 54a, and 54b establish communication with the internal space C of the device, which is normally closed, so that a batted ball flowing down from above can enter.

A decorative plate 56 imitating the shape of a horse's body is attached to cover the front ends of the rotation shafts 53 and 55, and a special game state has occurred in the variable prize winning device 5 at the center of the attached plate 56. A segment type display 57 is attached to display the number of consecutive times.

A concave portion forming wall 58 that protrudes into the mounting hole provided in the game board 1 is integrally formed in the center of the component board 50, thereby allowing the movable members 52a, 5
An internal space C surrounded by 2b and 54a, 54b is expanded rearward. A bottom wall 58a of the recess-forming wall 58 is sloped downward toward the front, and a substantially horizontal branching shelf 58b is formed at an intermediate position of the recess-forming wall 58.

Further, a prize receiving frame 59 projecting forward from the surface of the game board 1 is integrally formed at the lower part of the component board 50, and a front decorative plate 60 is attached so as to cover the front end of the winning receiving frame 59. The inside of the prize receiving frame 59 is normally divided into three parts by a pair of regulating pieces 71 that stand vertically, and the central entrance is a special winning area 61 that constitutes the special game generation condition and its continuation condition. , this special winning area 61
The left and right entrances are the general winning area 6 for giving the same winning profit as winning to the general winning opening 8 etc.
It is said to be 2. A rib 59a is formed on the bottom surface of the prize receiving frame 59 and is inclined downward toward the rear.
The winning ball is guided to the back of the game board 1.

A special winning detector SW ₄ (see FIG. 1) is provided on the back of the game board 1 corresponding to the special winning area 61 to detect a ball hit there.

The movable members 52a, 52b and 54a, 5
4b is rotated to communicate with the surrounding gaming area, the ball that flies into the interior from above flows down along the upper surface of the movable members 52a, 52b and directly towards the entered prize receiving frame 59. Either it falls, or it once collides with the diverting shelf 58b and is guided backwards, then falls onto the bottom surface 58a, and then flows down toward the prize receiving frame 59. And prize winning slot 59
Win a prize in either the special prize area 61 or the general prize area 62 within.

In this embodiment, a rotating shaft 72 is fixed to the lower end of the pair of regulating pieces 71, and this rotating shaft 72 is connected to the winning receiving frame 59 and the pair of supporting recesses 5 formed on the bottom surface.
It is inserted into a through hole 63a formed at the lower end of a pair of separation walls 63 at the rear along line 9b. As shown in FIG. 4, a link member 73 having an engagement pin 74 at its tip is attached to the rear end of the rotation shaft 72 that protrudes rearward through the through hole 63a, and the engagement pin 74 is connected to a solenoid. 75 plunger 75a
A pair of engagement holes 7 formed in the operating piece 76 at the tip
6a, respectively.

As a result, when the solenoid 75 is energized, the engagement pin 74 is pushed up by the plunger 75a, the pair of rotation shafts 72 are rotated in opposite directions, and the regulation piece 71 at the tip is rotated as shown in FIG. It rotates so that it falls outward as shown by the broken line A.
Therefore, the special winning area 6 in the center of the winning frame 59
The entrance of No. 1 is enlarged, making it very easy for the ball to hit the prize. On the other hand, when the solenoid 75 is demagnetized, the plunger 75a is lowered by the return spring 75b, and the engagement pin 74 is pushed down. Therefore, the rotation shaft 72 is rotated in the opposite direction to the above, the pair of regulating pieces 71 are erected to the original vertical position, the area of the entrance of the special winning area 61 is reduced, and the ball hit there is reduced. You will be moved to a state where your chances of winning a prize are low. The regulating piece 71 to the solenoid 75 constitute a winning opening adjustment means 70.

In addition, in the space C inside the recess forming wall 58,
A moving body 65 imitating the shape of a jockey and its operating rod 66
The movable member 52 is arranged so that it protrudes.
It is designed to be moved up and down by a drive source separate from the drive sources for a and 52b. This moving body 65
is usually a decorative plate 5 as shown by the broken line B in FIG.
Although it is hidden behind the back of 1 and cannot be seen,
When a special game state occurs or when a continuation condition is met, the game is operated to temporarily appear and disappear, thereby increasing interest in the game.

Next, using FIG. 5, electrical control is performed to drive the drive source of the variable winning device 5, the drive source 75 of the winning hole adjustment means 70, etc. based on the winnings in the special winning holes 7a to 7c, etc. An embodiment of the device will be described along with its operation.

The detection signals of the winning detectors SW ₁ and SW ₂ provided corresponding to the special winning holes 7b and 7c are supplied to the flip-flop F1 via the waveform shaping circuit 8, and the detection signals are supplied to the flip-flop _F1 through the waveform shaping circuit 8. When the ball hits 7c, the flip-flop _F1 is set and its output is set to high level. Then, the AND gate _G1 is opened, and the output Q of the flip-flop _F1 is changed to low level and passed through the AND gate _G2 and the OR gate _G3 .
The reset of timer counter TMC is released.
This makes the output Q ₀ of timer counter TMC
(See Figure 6) is the above AND gate that is open.
is supplied to the solenoid drive circuit DR ₁ via G ₁ ,
The movable member 52a is moved by driving the solenoid SOL ₁ .
~ 54b is opened and closed.

Therefore, when the first opening/closing operation of the movable members 52a to 54b is completed, the timer counter
TMC output Q ₄ changes to high level, which causes
It is supplied from AND gate _G4 to the reset terminal of flip-flop _F1 via OR gate _G5 , causing it to be reset. Therefore, the AND gate _G1 is closed, the output _Q1 of the timer counter TMC is no longer supplied to the solenoid drive circuit _DR1 , and the drive of the solenoid _SOL1 is stopped. In other words, by winning a prize in the special winning openings 7b and 7c, the movable member 52a
54b opens and closes only once and then stops.

On the other hand, the detection signal of the winning detector SW ₃ provided corresponding to the special winning hole 7a is supplied to the second flip-flop F2 via the waveform shaping circuit 82, and the detection signal is supplied to the second flip-flop _F2 through the waveform shaping circuit 82. When a ball hits a prize, the flip-flop _F2 is set and its output Q is set to a high level. Then, this output Q causes the first flip-flop to
F ₁ is set and as above,
The solenoid SOL ₁ is driven, and the movable members 52a~
54b is opened and closed. At this time, since the output of the second flip-flop _F2 is at a low level, the AND gate _G4 is closed.
The flip-flop _F1 is not reset by the output _Q4 of the timer counter TMC. Therefore, the movable members 52a to 54b are further opened and closed.

However, after the movable members 52a to 54b have been opened and closed twice, the output _Q2 of the timer counter TMC changes to a high level (FIG. 6). This is
It is supplied to flip-flop _F1 through OR gate _G5 , causing it to reset. As a result, the AND gate
G ₁ is closed and the output of timer counter TMC
The supply of Q ₀ is cut off and the drive of solenoid SOL ₁ is stopped. In other words, the movable members 52a to 54b are opened and closed only twice due to winning in the special winning opening 7a. Furthermore, at the same time as the flip-flop _F1 is reset, the flip-flop _F2 is also reset to prepare for the winning of the next hit ball.

In this way, when the movable members 52a to 54b are opened and closed due to a winning in the special winning openings 7a and 7b, the ball flies into the variable winning device 5, and when the ball enters the general winning area 62, the game The state does not change, and the movable members 52a to 54b open and close a predetermined number of times (once or twice), and then shift to a stopped state.

When the ball that flies into the variable winning device 5 enters the special winning area 61, the special winning detector SW ₄ provided correspondingly detects this, and the detection signal is sent to the waveform shaping circuit 83. Through
Supplied to AND gate G ₆ . This AND gate
G ₆ normally takes the logical OR of the output of counter CNT ₁
Since it is opened by the output of OR gate G ₇ ,
The special winning detection signal is supplied to the third flip-flop _F3 through the AND gate _G6 to set it. In addition, the special winning detection signal is
It is supplied to the timer counter TMC via the OR gate _G3 , which is reset and starts counting again from "0".

When the special winning detection signal comes in, the output of flip-flop _F3 changes to low level and the OR
It is supplied to the fourth flip-flop _F4 through the gate _G8 , and its reset state is released. Therefore, the AND gate _G9 is opened by the output of the flip-flop _F4 and the output Q of the flip-flop _F3 , and the output _Q5 of the timer counter TMC (see Figure 6) is supplied to the solenoid drive circuit _DR2 , and the continuous display is performed. The member driving solenoid SOL ₂ is temporarily and repeatedly excited to move the movable body 65 up and down.

This vertical movement of the moving body 65 continues until the output _Q1 of the timer counter TMC changes to high level (approximately 1.6 seconds), and when the output _Q1 of the timer counter changes to high level, the flip-flop _F4 is set and its output changes to a low level, closing AND gate _G9 . Also, flip-flop
When _F4 is set by timer counter output _Q1 , its output Q changes to high level.
AND gate G ₁₀ is opened.

This causes the output of timer counter TMC to
Q ₀ is supplied to the solenoid drive circuit DR ₁ , the solenoid SOL ₁ is driven, and the movable members 52a to 5
4b is opened and closed. And the movable member 52a
54b has been opened and closed 18 times, the output _Q3 of the timer counter TMC is changed to high level, so the third flip-flop _F3 is reset via the OR gate _G11 , and further, the output of the third flip-flop F3 is reset. Flip-flop _F4 is reset, output Q changes to low level, and AND gate _G10 is closed. Therefore, one cycle ends when the output _Q1 of the timer counter TMC is no longer supplied to the solenoid drive circuit _DR1 and the movable members 52a to 54b have opened and closed 18 times.

On the other hand, after the start of the special game, a detection signal from the detector SW ₅ that detects a winning ball in the variable winning device 5 is sent to the counter via the waveform shaping circuit 84.
Input to CNT ₂ and output of counter CNT ₂
The decoder DEC ₂ decodes Q ₀ to _{Q 3} and drives the segment type display LED ₂ to display the number of winning balls.
When the count value of the counter CNT ₂ reaches 6, the output of the AND gate G ₁₄ which uses the counter outputs Q ₁ and Q ₂ as input signals changes to high level, and the output is passed through the OR gate G ₁₆ . flipflop F ₅
is supplied to set it.

Further, the output _Q6 of the timer counter TMC is input to the other input terminal of the OR gate _G16 , and this output _Q6 is applied to the movable members 52a to 54.
When the number of openings and closings of b reaches 12, it is changed to high level and flip-flop _F5 is set.
The output Q of the flip-flop _F5 is supplied to the drive circuit _DR3 through an AND gate _G16 which, like gate _G6 , is normally open.

Therefore, after the start of the special game, the number of winnings in the variable winning device 5 becomes 6 or the movable members 52a to 54
When b opens and closes 12 times, solenoid SOL ₃
75 is excited by the drive circuit _DR3 . As a result, the regulation piece 71 in the special winning area 61 is rotated to open left and right, and the entrance to the special winning area 61 is enlarged, while the entrance to the general winning area 62 is reduced. Therefore, the ball hit into the variable winning device 5 is very likely to win into the special winning area 61. As a result, the conditions for continuation of the special gaming state are met, and the probability of moving to the next cycle is significantly increased.

When a ball hits the special winning area 61 in this state, the detector SW ₄ detects this and moves to the next cycle based on the detection signal.
It is supplied via AND gate _G6 to flip-flop _F5 , causing it to be reset. Therefore, the solenoid SOL ₃ 75 is demagnetized and the regulating piece 71 returns to its original vertical position, and the entrance to the special winning area 61 is quickly reduced to a state where it is difficult to win.

Note that the counter CNT ₂ that counts the number of winning balls to the variable winning device 5 is also reset by the detection signal from the special winning detector SW ₄ and starts counting. The number of balls won when the movable members 52a to 54b are opened and closed by winning to the special winning holes 7a to 7c before the game starts is not included in the counted value. The ball hit into the special winning area 61 is detected by the detector SW ₄ and then detected again by the detector SW ₅ . Therefore, counter CNT ₂
The winning ball that enters the special winning area 61 is counted as the first ball after the start of the cycle.

When the winning ball enters the special winning area 61 and advances to the next cycle, the counter is activated by the detection signal from the special winning detector SW ₄ .
CNT ₂ is reset and counts the number of winning pitches in the next cycle starting from "0" again, and the counter
CNT ₁ is counted up and this counter
By decoding the output of CNT ₁ with decoder DEC ₁ , the number of continuations is displayed on segment type display LED ₁ .

Furthermore, when the count value of the counter CNT ₁ reaches "8", the output signal of the OR gate _G7 which uses its outputs _Q0 to _Q2 as input signals changes to low level, and the output Q of the flip-flop _F5 goes high. By closing the AND gate _G17 , the solenoid is activated by the solenoid drive circuit _DR3 .
It is designed not to drive SOL ₃ .

In addition, in the 8th cycle, the AND gate _G6 is closed by the output of the OR gate _G7 , so even if the ball hits the special winning area 61, the detection signal of the special winning detector _SW4 will not reach the flip-flop F. ₃ will no longer be supplied. As a result, in the special game of the 8th cycle, the signal Q ₃ notifying the opening/closing of the 18th time from the timer counter TMC or the output of the counter CNT ₂ for counting the number of winning balls to the variable winning device 5.
From AND gate G ₁₅ with Q ₁ and Q ₂ as input signals
The flip-flop _F3 is reset by the earlier signal of the 10th prize winning signal, and the special game state ends. Further, at the same time as flip-flop _F3 is reset, counter _CNT1 , which counts the number of continuations, is also cleared.

In addition, in the 1st to 7th cycles, the movable member 5
2a to 54b are opened and closed 18 times or the winning ball is 10
If there is no prize in the special prize area 61 by the time the number reaches the number of prizes, the timer counter
The flip-flop _F3 is reset by the output _Q3 of the TMC, and the special gaming state is ended.

As explained above, in this example,
Variable prize winning device 5 if the movable member is opened and closed 12 times
Special winning area 6 by the time 6 batted balls win prizes within
If there is no winning in 1, the regulation piece 71 opens and the winning opening of the special winning area 61 is enlarged, and the special winning area 6
It becomes easier to hit the ball to 1. Therefore, once the special game starts, there is a very high possibility that the special game will continue under conditions close to the preset maximum game conditions, thereby fully satisfying the expectations of the players. In addition, even if a special game state occurs, it is not guaranteed that the special game will be repeated up to eight times, so it is possible to give the player a thrill during the game and increase expectations for the fulfillment of the continuation conditions. can.

FIGS. 7 and 8 show a second embodiment of the winning hole adjustment means 70 of the special winning area 61 provided in the variable winning device 5. FIG.

In this embodiment, a storage section 77 is provided on the lower surface of the winning frame 59 at the bottom of the variable winning device, and a pair of slide members 48 are inserted into the storage section 77 so as to be slidable in the left and right direction. Horizontal support pins 79 protruding inward are implanted in the side walls of the storage portion 77, and compression springs 80 are fitted around each of the support pins 79, thereby causing the pair of The slide members 78 are urged toward each other.

Further, each of the slide members 78 is integrally formed with a regulating piece 71 that projects upward, and the regulating piece 71 projects upward from an opening 59d formed in the winning frame area. Therefore, a special winning area 61 and a general winning area 62 are configured, which are separated by the regulation piece 71 within the winning receiving frame 59.

Behind the winning frame 59, a solenoid 75 is disposed in an orthogonal position as shown in FIG.
The operating cam 81 is arranged so that the trapezoidal operating cam 81 fixed to the tip of the plunger 75a of the solenoid 75 can engage between the slide members 78.
The tip thereof faces into the storage section 77.

In the winning opening adjustment means 70 of this embodiment, when the solenoid 75 is excited, the plunger 75a moves forward and pushes the operating cam 81 between the slide members 78. Therefore, as the actuating cam 81 moves forward, it pushes the pair of slide members 78 apart to the left and right.
As shown by the broken line D in the figure, the distance between the pair of regulating pieces 71 is widened, the winning opening in the center, that is, the special winning area 61 is opened wide, and it becomes easier for the batted ball that flies into the variable winning device 5 to win a prize.

On the other hand, when the solenoid 75 is demagnetized, the plunger 75a retreats due to the restoring force of the return spring 75b, and the operating cam 81 is pulled out from between the slide members 78. Therefore, the pair of slide members 78 move toward each other due to the restoring force of the compression spring 80, and the winning opening of the special winning area 61 is narrowed.
It becomes difficult to hit the ball.

In the above embodiment, an adjustment piece 89 is fixed to the tip of the regulation piece 71, and the ease with which a ball hits the special winning area 61 can be finely adjusted depending on the shape of the adjustment piece 89. Therefore, a plurality of adjustment pieces 89 having different shapes are prepared in advance, and the movable member 52
Even if the ease of winning a prize in the special winning area 61 changes due to differences in the shape, size, etc. of a to 54b and the internal space, it can be corrected by simply replacing the adjustment piece 89 at the tip of the regulation piece 71. It is possible to prevent the winning rate of the special winning area 61 from differing depending on the type of variable winning device.

Next, the winning opening adjustment means 70 of the special winning area 61
A third example will be described using FIG. 9.

In this embodiment, a pair of separation walls 90 are formed within the winning frame 59, and a special winning area 61 is formed in the center.
Further, general winning areas 62 are formed on the left and right sides. A guide groove 91 is formed in the horizontal direction at the upper end of the mutually opposing surfaces of the pair of separation walls 90,
A U-shaped regulating piece 71 is slidably inserted into the guide groove 91. This regulating piece 71 is fixed to the tip of the plunger 75a of the solenoid 75.

Therefore, the winning opening adjusting means 70 of this embodiment is as follows:
In a normal state in which the solenoid 75 is not excited, the regulating piece 71 is deeply inserted between the pair of separation walls 90 along the guide groove 91, as shown in the figure. Therefore, the winning opening in the special winning area 61 is limited to the size of the U-shaped recess formed in the regulating piece 71, and the winning opening becomes narrow.

However, when the solenoid 75 is energized, the plunger 75a retreats and the regulating piece 71 is pulled out from the guide groove 91. Therefore, the winning hole in the special winning area 61 widens to the fullest distance between the separation walls 90, making it easier for the ball to win.

Although three embodiments have been described above, the structure of the winning a prize opening adjusting means 70 of the special winning area 61 is not limited to the above embodiment, and various modifications can be considered.

In addition, in the embodiment, as an example of a control system in a pachinko game machine equipped with a variable winning device having a winning opening adjusting means, the movable members 52a to 54b are
When the variable winning device 5 opens and closes 12 times or 6 winning balls are placed in the variable winning device 5, the winning hole adjustment means 70 is operated to enlarge the winning hole in the special winning area 61. Not limited to control method,
For example, when the movable members 52a to 54b open and close 14 times or when 8 winning balls are received, the winning hole adjusting means 70
It is also possible to make it work.

Furthermore, the entry winning hole adjusting means may be configured to temporarily reduce the winning hole in the special winning area at the start of the special game, and then expand (return to original size) the winning hole when a predetermined condition is met. .

In the above embodiment, the present invention is applied to a variable winning device that increases the winning rate by swinging a pair of movable wing pieces left and right, but the present invention is not limited thereto. The so-called Atatsuka type has a special winning area and a general winning area inside, and has a relatively wide winning opening with one rotatable panel that can be opened and closed, and the winning opening can be opened by rotating it forward. It can also be applied to a variable prize winning device.

[Function/Effect] A winning opening adjustment means that can enlarge or reduce the opening area of the special winning area is provided in the variable winning device that has a general winning area and a special winning area inside, and is set in advance in the electrical control device. When the specified conditions are met, the prize opening in the special prize area is enlarged so that winning batted balls can easily enter the special prize area, so the chance of the special game being continued is increased. Due to this effect, the special game is executed under conditions close to the best within the preset conditions, and a relatively large number of balls are guaranteed to be paid.
