Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention can repeatedly convert a variable winning device to a second state advantageous to a player on the condition that a special game right generating condition has been achieved. The present invention relates to a pachinko machine that performs a special game.

<Prior Art> A first state disadvantageous to the player and a second state advantageous to the player are achieved by achieving a special game right generation condition based on a hitting ball prize in a special prize area or the occurrence of a special stop mode of the variable display device. There is known a pachinko machine that performs a special game in which a variable winning device that can be converted into two states can be repeated a predetermined number of times in a continuous game in which a continuous game is converted into a second state that is advantageous to a player.

In a pachinko machine that performs a special game using such a variable winning device, the special game does not occur frequently,
Although the game is very rarely generated several times per hour or several times per day, the game profit that can be obtained by the player when the special game is executed is very large. Is one of the biggest concerns in gaming.

On the other hand, the amusement store side also makes it possible for the player to fully enjoy the special game that has finally occurred by adjusting the continuous game in the special game so that the continuous game is performed to the maximum (executed up to the maximum number of times). By increasing the game profit that can be obtained by the player in the game as much as possible, the expectation of the player for the special game is enhanced.

Further, in a pachinko machine capable of performing such a special game, a maximum number of repetitions of the continuous game in the special game is set to one type in advance for each game machine. Since the continuation condition of the game is adjusted to be relatively easily achieved, the amount of game profit that can be obtained by the player in the special game in which the predetermined number of continuous games is executed is substantially reduced according to the type of the pachinko machine. It is constant.

<Problems to be Solved by the Invention> However, in the conventional pachinko machine described above, if the special game right generating condition is set to be easily achieved, a relatively large number of special games will be generated. Therefore, it is interesting for a player who can win a large amount of prize balls, but in a setting where the loss of the game store side increases and it is difficult to generate a special game right, the player Although the loss at the amusement store side is small because the prize balls that can be acquired are reduced, the interest of the player is weakened because the expectation for achieving the special game is not satisfied, and the player can play the game with such a pachinko machine. If you do so, you will eventually lose your game store.

Accordingly, an object of the present invention is to provide a pachinko machine that can maintain a good balance of profits between a player and a game store and can effectively enhance the interest of the player.

<Means for Solving the Problems> In order to solve the above problems, the pachinko machine according to the present invention provides a special game right occurrence determination unit (for example, a special game right occurrence determination unit that determines that a predetermined special game right occurrence condition has been achieved). A special prize detector 35) and a variable prize device (for example, the central prize device 4) capable of converting the movable ball receiving member (11, 11) into a first state disadvantageous to the player and a second state advantageous to the player. )
The variable winning device is set on the basis of a predetermined condition (for example, 10 counts to a predetermined time), as a necessary condition that the special game right occurrence determination means determines that the special game right occurrence condition has been achieved. A special game control means (for example, an electric control device) for executing a special game in which the continuous game is converted to the second state a predetermined number of times, wherein the special game control means fulfills a special game right generating condition. Repeatable number determining means (for example, a special game selecting means or a special game selection display) for determining any one of a plurality of repeatable times of a predetermined continuous game based on the game profit given to the player based on Driving means, etc.), and a special game execution means for performing a special game based on the game conditions determined by the repeatable number determination means.

<Operation> When the special game right occurrence determining means determines that the predetermined special game right occurrence condition has been achieved, the continuous game number determining means sets the variable winning device from the first state to the second state based on the predetermined condition. The number of possible continuations of the continuous game to be converted into the state is determined to be one of a plurality of predetermined possible continuations, and the special game is executed by the special game execution means within the determined number of times. Is changed according to the result of determination by the continuous game number determination means.

<Example> Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a game section 3 surrounded by guide rails 2 is formed on the surface of a game board 1 of a pachinko machine, and a central prize winning device 4 is provided substantially in the center of the game section 3, and the central prize apparatus is provided. A first special winning opening 5, a second specific winning opening 6, and a third specific winning opening 7 are arranged below the device 4.

The central winning device 4 as a variable winning device that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player has an opening 9 substantially at the center of a mounting board 8 to which the surface of the game board 1 is mounted. And an armor portion 10 that is slightly longer than the width of the opening portion 9 protrudes from the surface above the opening portion 9, and a horizontally long, shelf-shaped movable ball receiving member is provided below the armor portion 10. 11 and 11 are provided movably in the left-right direction, and a blocking wall 12 is provided at the edge of the opening 9 below the movable ball receiving members 11 and 11 so as to project upward in a substantially U-shape. Is provided with a recessed chamber 13 communicating with the opening 9, a special game selection indicator 14 is provided on the front wall in the recessed chamber 13, a special winning opening 15 is provided in the lower center of the recessed room 13, and the special winning opening 15 is provided. General winning openings 16 and 16 are respectively opened forward and left, and a probability control member 17 is rotatably facing left and right of the special winning opening 15.

The movable ball receiving member 11 is a horizontally long shelf-like member formed at one end with a protrusion 18 having an inclined surface inclined downward in the left-right direction. The movable member 11 is formed by recessing the tip of a connecting member (not shown) projecting from the rear surface. It is connected to a first drive source such as a solenoid provided on the back side of the chamber 13. The left and right movable ball receiving members 11, 11 are always the second
As shown by the solid line in the figure, the projection 18 of the left movable ball receiving member 11 approaches the front of the opening 9 and is positioned between the lower left end of the armor 10 and the upper left end of the blocking wall 12. At 19, the protrusion 18 of the right movable ball receiving member 11 stops at the right ball passing portion 20 between the right lower end of the armor portion 10 and the right upper end of the blocking wall 12, respectively, and the left and right ball passing portions 19, 20 The effective height is smaller than the ball diameter. Therefore, in this state, the hit ball that has flowed down
To prevent the ball from entering the special winning opening 15 or the general winning opening 16 (unfavorable for the player)
It becomes the first state. On the other hand, when the left and right movable ball receiving members 11 move outward by the driving of the first drive source, as shown by the second dotted line, the protrusion 18 of the left movable ball receiving member 11 becomes the left ball passing portion 19. The projection 18 of the movable ball receiving member 11 on the right side deviates from the right ball passage portion 20 and protrudes greatly to the right side of the armor portion 10. Therefore, in this state, the hit ball that has flowed down is received on the movable ball receiving members 11 and 11 and passes through the ball passing portions 19 and 20 to be awarded in the special winning opening 15 and the general winning opening 16 (advantageous for the player). The state becomes the second state. The movable ball receiving member 11 in the present embodiment
After passing through the ball passage portions 19 and 20, the ball received by the first rolls into the concave chamber 13 and then rolls toward the opening 9 on the bottom surface, and the special winning opening 15 or the general winning opening 16 is formed. There are a prize winner and a prize winner who directly wins the special winning opening 15 or the general winning opening 16 from the end of the movable ball receiving member 11.

The probability control member 17 has support shafts on the left and right above the special winning opening 15.
21 and 21 are rotatably protruded, and the middle of the length of the vertical member 23 having the decorative portion 22 formed at the lower end is fixed to the tip of the support shaft 21,
At the upper end of a vertical member 23 located above the support shaft 21, a ball sorting member 24 is provided substantially parallel to the support shaft 21, and a drive shaft 25 projecting rearward from a portion located below the support shaft 21 is attached to a mounting board. 8
The spring 27 is attached to the substantially elliptical cam 26
By pressing.

The cam is operated by the operation of a motor 28 provided on the back side of the mounting board 8.
26 rotates, the rear end portion of the drive shaft 25 is pressed against the long diameter portion of the cam 26, as shown in FIGS. 3 and 4 the solid line, and the distance L ₁ between the left and right ball sorting member 24, 24 is minimized Become. Therefore, the probability that the ball passes between the left and right ball sorting members 24, 24, that is, the probability that the ball enters the special winning opening 15, is minimized. Then, when the cam 26 rotates substantially 90 degrees and the rear end portion of the drive shaft 25 is pressed against the short diameter portion of the cam 26, as shown by the dotted line in FIG. 4, the distance L ₂ between the left and right ball distribution members 24, 24 is obtained. Is the largest. Therefore, the probability that the ball passes through the left and right ball sorting members 24, 24, that is, the probability that the ball enters the special winning opening 15, is maximized.

In this way, when the cam 26 is rotated, the left and right ball distribution members
Since the interval between 24 and 24 is enlarged or reduced, the winning probability to the special winning opening 15 can be controlled according to this interval. In this embodiment, as shown in FIG.
A light-shielding plate 30 having slits 29, 29 formed at opposing positions is fixed to the shaft of the cam 26, and a photosensor 31 faces the light-shielding plate 30, and the position of the probability control member 17 is determined by a signal from the photosensor 31. Is configured to be detected.

Therefore, the right and left winning probability control members 17, 17 can be stopped in a state where the interval between the ball sorting members 24, 24 is minimized. Note that the probability control members 17 and 17 in the present embodiment rotate around the respective support shafts 21 and reduce the probability of winning into the special winning opening 15 when stopped in a C-shape, so that this C-shape is used. Alternatively, the side edge portion of the probability control member 17 that has stopped may function as a ball guide member that guides the ball to the specific winning openings 6 and 7.

The special game selection display 14 includes a first display plate 32 and a second display plate 33 made of a light-transmitting plastic, each displaying a special game mode.
And the third display panel 34 are arranged in a heart-shaped ring, and a light-emitting source such as a lamp electrically connected to an electric control device is provided on the back side of each display panel. And this special game selection indicator
Reference numeral 14 designates an MO written on each display panel by sequentially lighting one of the light emitting sources in sequence by a signal from the electric control device.
DE-1, MODE-2, and MODE-3 are illuminated one by one,
When a ball enters the special winning opening 15, based on a signal from the special winning detector 35 that has detected the ball, the electric control device stops the light emitting source from moving and continuously lights one of the light emitting sources,
Select a special game mode.

That is, in the present embodiment, when the ball enters the special winning opening 15, the MDE-1, MODE-2, and MODE-3 illuminated at this time are used.
The special game is configured to be started in any one of the modes, and the special prize detector 35 serves as special game right occurrence determination means for determining that a predetermined special game right occurrence condition has been achieved. It works. The central prize winning device 4 is set to a second condition based on a predetermined condition, on condition that the signal from the special prize detector 35 is received.
The above-described electric control device that executes a special game (detailed later) in which the continuous game is converted to a state a predetermined number of times functions as a special game control means.

Next, a game in a pachinko machine provided with the above-described central winning device 4 will be described. In a normal state, the movable ball receiving members 11 and 11 of the central winning device 4 stop in the first state in which no ball is received, and the probability control member 17 stops in a state where the winning probability to the special winning opening 15 is minimized. , Special game selection display
Reference numeral 14 sequentially lights one light emitting source to sequentially illuminate MODE-1, MODE-2, and MODE-3 written on each display panel at predetermined time intervals.

When the ball flowing down in the gaming section 3 enters the first specific winning opening 5 in the above-described state and the first specific winning detector 36 detects this ball and sends a signal to the electric control device, the electric control device Changes the first driving source of the central winning device 4 for a predetermined short time (for example, 0.
Excited only twice (for 8 seconds), the ball enters the second specific winning opening 6 or the third specific winning opening 7, and the second specific winning detector 37 or the third specific winning detector 37
When the specific winning detector 38 detects this ball and sends a signal to the electric control device, the electric control device operates for a predetermined time (for example, 0.5
(For one second). Therefore, when the ball enters the first specific winning opening 5, the movable ball receiving members 11, 11 of the central winning device 4.
Moves right and left twice for 0.8 seconds to convert to the second state,
When the player enters the second specific winning opening 6 or the third specific winning opening 7, the movable ball receiving members 11, 11 change to the second state only once for 0.5 second.
In this way, when the movable ball receiving members 11, 11 of the central winning device 4 change from the first state to the second state, the ball that has flowed down in the game section 3 flows down onto the movable ball receiving member 11, Flows down from the movable ball receiving member 11 on the bottom surface of the concave chamber 13 or directly flows down from the movable ball receiving member 11 to enter either the special winning opening 15 or the general winning opening 16. When the ball enters the general winning opening 16, the ball flows out to the back side of the game board 1 and becomes a winning ball, but the game state does not change. On the other hand, when the ball enters the special winning opening 15,
The special winning detector 35 detects this ball and sends a signal to the electric control device. In addition, the ball which entered special winning opening 15 is game board 1
Is ejected to the back side of the ball and becomes a winning ball.

When the electric control device receives the signal from the special prize detector 35, it detects that the special game right generating condition has been achieved, stops the blinking movement of the special game selection display 14, and selects the mode of the special game. I do. In the present embodiment, the ball is in the special winning opening 15 and the mode is displayed on the display panel that was lit when the special prize detector 35 detected the ball, for example, the first display panel was lit. If the ball enters the special winning opening 15 while the player is present, a special game of MODE-1 is started.

In the special game of MODE-1, the movable ball receiving members 11 and 11 of the central winning device 4 have a predetermined number of predetermined times (for example, 18 times for 0.8 seconds).
Only the conversion from the first state to the second state is one cycle, and when the ball enters the special winning opening 15 during this cycle, the cycle is updated immediately at that point, and the cycle can be updated up to 8 times If the ball does not enter the special winning opening 15 even after the movable ball receiving members 11, 11 have been changed from the first state to the second state up to the 18th time in the cycle, regardless of the number of remaining cycles, Ends the special game. When a predetermined (for example, 10) ball is won in the central winning device 4 in a certain cycle, the special game ends at that point in time regardless of the number of remaining cycles (so-called 10 count regulation).

Further, when a predetermined state is reached in a certain cycle (in this embodiment, five balls enter the general winning opening 16 or 10 seconds have elapsed since the start of the cycle),
The motor 28 rotates the cam 26 and the left and right probability control members 17, 17
The distance to increase the winning probabilities of the special winning hole 15 by varying between L ₁ of L _2, lower the winning probabilities of the general winning opening 16. That is, when the state is set in advance,
By increasing the probability that a ball enters the special winning opening 15, it is easy to move to the next cycle, and it is easy to continue a special game advantageous to the player. Incidentally, when the ball is update cycle enters the special winning hole 15 is performed, electric control device stops probability control members 17 of the left and right stops the operation of the motor 28 in a state of spacing L _1.

The special game of MODE-2 may be selected depending on the timing at which the ball enters the special winning opening 15 and is detected by the special winning detector 35. When one of the movable ball receiving members 11 and 11 is changed from the first state to the second state for a predetermined number of times (e.g., 18 times for 0.8 seconds) for a predetermined time, it is regarded as one cycle. The signal from the special prize detector 35 is stored in the electric control device, and the cycle is updated after the movable ball receiving members 11 and 11 have been converted a predetermined number of times for the above-mentioned predetermined time, and the cycle is updated up to eight times. It is possible. In this cycle, the movable ball receiving members 11 are moved from the first state to the second state.
If the ball does not enter the special winning opening 15 even after being changed to the 18th state, the special game is completed in that cycle regardless of the number of remaining cycles, and a predetermined number is given to the central winning device 4 in a certain cycle. When 10 (for example, 10) balls are won, the special game ends at that point regardless of the number of remaining cycles.

Further, when a predetermined state is reached in a certain cycle (in this embodiment, five balls enter the general winning opening 16 or 10 seconds have elapsed since the start of the cycle),
The motor 28 rotates the cam 26 and the left and right probability control members 17, 17
Is changed to increase the probability of winning in the special winning opening 15 to make it easier to move to the next cycle. Like this, MODE
In the special game, when the ball enters the special winning opening 15 in the middle of the cycle, this is stored, and the cycle is updated after the conversion for the predetermined number of times in the cycle is completed. The player can play the game in a more advantageous state than MODE-1.

The special game of MODE-3 may be selected according to the timing at which the ball enters the special winning opening 15 and is detected by the special winning detector 35. The movable ball receiving members 11 and 11 convert the first state to the second state for a predetermined number of times (for example, 18 times for 0.8 seconds) for a predetermined time. However, even if the ball enters the special winning opening 15 during this special game, the cycle such as MODE-1 or MODE-2 is not updated, and a predetermined number (for example, 10) is stored in the central winning device 4. When the ball has won, the special game is completed at that point in time regardless of the number of times the remaining movable ball receiving members 11, 11 are opened and closed.

Note that the special games of MODE-1, MODE-2, and MODE-3 described above are examples, and the difference in the game content depending on the mode of the special game can be appropriately set by the electric control device. . Further, the electric control device sequentially turns on the special game selection means for selecting the mode for the special game based on the signal from the special winning detector 35 and the light emitting source unit of the special game selection display 14 one by one. There is no special game selection display driving means for stopping the flashing movement of the light emitting source by a signal from the special winning detector 35 or by a signal from the special game selecting means, and no special game executing means for executing the selected special game. I have it.

That is, in this embodiment, the special game selection display
At the same time as performing the display control of 14, the display of the special game selection display 14 is stopped at a predetermined timing (special winning ball detection timing of the special winning detector 35), and the display is stopped in advance corresponding to each display position of the special game selection display 14. An electric control device (special game selection means, special game selection display driving means, special game selection means, special mode selection means, special game selection means) which determines a MODE according to the determined repeatable number of times and performs a special game under the game conditions according to the determined MODE. The function of the number-of-repetitions determination means and the special game execution means is realized by the device having functions such as execution means.

In the present embodiment, the number of repeatable continuous games in MODE1 and MODE2 is set to eight, and the number of repeatable continuous games in MODE3 is set to one. At the same time, the probability that the number of repeatable times is 8 was set to 2/3, and the probability that the number of repeatable times is 1 was set to 1/3. As described above, by appropriately setting the upper limit value of the number of repeatable times or appropriately setting the occurrence probability, the average number of repeatable special games in the pachinko machine can be adjusted.

The probability control member 17 used for achieving the continuation condition in the variable winning device 4 is not limited to the wing-shaped member described above, and has a function of changing the probability of winning in the special winning opening 15. Any configuration may be used.

For example, in the second embodiment of the center winning device 4 attached to the game board 1 shown in FIG. 5, an opening 9 is opened substantially at the center of a mounting board 8 attached to the surface of the game board 1, and the opening 9 is provided. An armor portion 10 that is slightly longer than the width of the opening 9 protrudes from the upper surface of the armature, and wing-piece-shaped movable ball receiving members
The movable ball receiving members 11 and 11 are provided rotatably, a blocking wall 12 is protruded from the edge of the opening 9 below the movable ball receiving members 11 and 11, and a recess communicating with the opening 9 is provided on the back side of the mounting substrate 8. A chamber 13 is provided, and notches 39, 39 are provided on the left and right sides of the inside of the concave chamber 13, and the movable ball receiving members 11, 11 are slightly inclined downward from the height of the base end of the shaft attachment toward the back. Shelf board 40
In addition to providing the sub general winning openings 41a, 41a on the left and right of the front wall portion of the concave room 13, both sub general winning openings 41a, 4
Opened at the entrance 41b during 1a, a notch 39 of the shelf 40 located in front of each sub general winning opening 41a is provided with a solenoid 43 and a shutter 43 which can be moved back and forth by a second drive source 42, A vertical communication port 41c for dropping the sphere entering the entrance 41b onto the bottom surface of the recessed chamber 13 is formed at the back of the opening, a special winning opening 15 is provided at the center in front of the opening 9, and the special winning opening 15 is formed. Main general winning openings 44, 44 are opened on the left and right, respectively, and the windmill-like probability control members 17, 17 are rotated above each partition member 45 that partitions the special winning opening 15 and the main general winning opening 44. I'll let you freely.

The shutter 43 is always stopped in the notch 39 of the shelf 40 as shown in FIGS. Therefore, in this state, the movable ball receiving members 11, 11 rotate in the direction in which each upper end is tilted outward from the first state in which the movable ball receiving members 11, 11 do not receive the ball by the driving of the first driving source such as the solenoid provided on the back side of the concave chamber 13. When the ball is converted to the second state in which the ball can be easily received, the movable ball receiving member 1
The balls received by the balls 11 and 11 roll on the shelf board 40 in the recessed chamber 13 to win the sub general winning opening 41a or the communication opening 41 from the entrance 41b.
Through c, it flows down onto the bottom of the recessed chamber 13 and enters the special winning opening 15 or the main general winning opening 44. In this case, special winning entry
15 has a small number of balls flowing down on the bottom surface of the concave chamber 13, so it is difficult to enter.

Then, when the second drive source 42 is excited, as shown in FIG. 9, the shutter 43 retreats and the notch 39 of the shelf board 40 is opened. Therefore, when the movable ball receiving members 11 and 11 are changed from the first state to the second state in this state, the balls rolled on the shelf board 40 pass through the notch 39 or through the inlet 41b and the communication port 41c to form the concave chamber.
13 falls on the bottom surface, flows down toward the opening 9 on the bottom surface, and enters either the special winning opening 15 or the main general winning opening 44. In this manner, the shutter 43 opens the cutout 39 of the shelf 40 to increase the chance of the ball on the shelf 40 dropping on the bottom surface of the recessed chamber 13 and increase the probability of winning the special winning opening 15 .

The above-described probability control member 17 in the form of a windmill has a control plate 47 fixed to the tip of a shaft 46 arranged substantially parallel to the front-rear direction, and a disk 48 fixed to the front edge of the control plate 47. A motor 49 is connected to the rear end of the shaft 46, and a gear 50 provided on the shaft 46 is engaged with a gear 51 provided on the other shaft 46. Accordingly, when the motor 49 is operated, the left and right probability control members 17, 17 rotate in different directions, and as shown in FIG. 10, when the left and right control plates 47, 47 are positioned substantially parallel to the vertical direction, the control plates 47, , 47, the upper end interval VL ₁ is almost the same as the width of the partition members 45, 45, so that the ball flowing down in this range is made to win the special winning opening 15, and further rotated in the direction of the arrow, as shown in FIG. , since the left and right of the control plate 47 is located at the c shape, the interval VL ₁ upper interval of the control plate 47 is a VL ₂
Narrower than. Therefore, the probability of entering the special winning opening 15 decreases.

Note that a sphere on the outside of the upper interval VL ₂ of the control plate 47, 47 when flowing down, the sphere is finished in the main general winning hole 44 of the left or right. Then, the probability control members 17, 17 further rotate, and the twelfth
As shown, the left and right of the control plate 47 is positioned in the reverse V-shape, since it is expanded to the control plate 47 upper interval VL _3, it is possible to increase the probability of winning the special winning opening 15 . If the distance between the upper ends of the left and right control plates 47, 47 is minimized and this distance is set to be larger than the ball diameter, the ball passes through the distance as it is and enters the special winning opening 15. When a prize is won and the minimum interval is set to be smaller than the ball diameter, only the ball temporarily placed on the upper end of the left and right control plates 47 will win the special prize port 15.

As described above, the probability control member 17 according to the present embodiment
In addition to the fact that the shutter 43 provided in the notch 39 moves forward and backward, the hit ball easily falls on the bottom surface of the concave chamber 13 and makes it difficult to fall, and the rotating control plate 47 of the probability control member 17 Depending on the position, the range through which the ball passes can be enlarged or reduced, whereby the probability that the ball enters the special winning opening 15 can be adjusted. The probability control member 17 may be rotated at all times, but may be rotated when a predetermined condition such as starting to rotate after the movable ball receiving members 11 and 11 open and close ten times is satisfied. Is also good.

In the third embodiment shown in FIG. 13, three passage openings 52 are opened at the back of the shelf plate 40 provided in the concave chamber 13,
A ball passage detector 53 is provided in the center passage hole 52, and a special winning opening 15, a general winning opening 16, 16 are formed at the lower end of the bottom of the concave chamber 13 at an inclined lower end, and a so-called tulip-shaped probability is formed on the special winning opening 15. The control member 17 is provided. The probability control member 17 is provided toward the bottom surface of the concave chamber 13 of the pair of movable pieces 54, 54 that are opened and closed by driving the solenoid.

The probability control member 17 is always closed at an interval through which one ball can pass, as shown by the solid line in FIG. Therefore, in this state, the balls received by the movable ball receiving members 11 and 11 converted to the second state roll on the shelf plate 40 in the concave chamber 13 and fall from the left and right passage holes 52 onto the bottom surface. In this case, only the ball that has fortunately flowed down within the narrow gap between the movable pieces 54, 54 wins the special winning opening 15.

On the other hand, the ball rolling on the shelf 40
When the ball is detected by the ball passage detector 53, the electric control device that has received the signal from the ball passage detector 53 excites the solenoid and opens the movable pieces 54, 54 as shown by the dotted line in FIG. . When the movable pieces 54, 54 are opened, the tip distance between the left and right movable pieces 54, 54 is enlarged. Therefore, the ball can be introduced over a wide range, and the probability of winning the special winning opening 15 can be increased.

When the time set in the timer of the electric control device elapses, the solenoid is demagnetized and closes the left and right movable pieces 54, 54. As described above, the probability control member 17 according to the present embodiment converts the ball received by the movable ball receiving members 11 and 11 on condition that the ball passage detector 53 detects the ball, and sets the probability of winning to the special winning opening 15. Control.

<Effects of the Invention> As described above, according to the present invention, when the special game right occurrence determining means determines that the predetermined special game right occurrence condition is achieved, the variable winning device is set to the predetermined specified condition. The repeatable number of times of the continuous game to be converted to the second state based on the repeatable number of times is determined by the repeatable number determination means to be one of a plurality of predetermined repeatable numbers, and the continuous game is performed within the range of the repeatable number. Is performed by the special game execution means so that the special game can be repeated. Therefore, the number of repetitions of the continuous game is different for each special game.

Therefore, even if the continuous game in all the special games is executed to the maximum possible number of times, the profit obtained by the player by the prize ball related to one special game is different for each special game, and the conventional number of possible repeats is By setting a plurality of types of continuation times within the range, the average loss per game is reduced at the game store side. Store losses can be reduced.

Therefore, by appropriately setting the set value of the number of repeatable times determined by the repeatable number determination means, the determination probability, and the like, the profit balance between the game store and the player is appropriately maintained without reducing the number of occurrences of special games. Although it is possible to do, and the number of repeatable times will be different for each special game,
By appropriately generating the special game, it is possible to effectively maintain the player's expectation for the special game and enhance the interest in the game given to the player.
