Description

  The present invention relates to a pachinko gaming machine.

  In a pachinko gaming machine, a liquid crystal display device or a rotating drum type display device (also referred to as a reel type display device) is used as means for displaying a lottery process result executed based on establishment of a predetermined condition. Among them, the rotary drum type display device rotates a plurality of (usually three) cylindrical drums having a common axis around the common axis and variably displays a plurality of symbols arranged on the outer peripheral surface thereof, in the axial direction. A lottery processing result is displayed by notifying and displaying a predetermined row (usually three rows) of symbols (notifying the player).

  Such a rotary drum type display device is used only for displaying the lottery processing result described above, and it has never been used for other purposes because of its structure. Needed to be supplemented with another symbol display device (see Patent Document 1). Also, it has been proposed that a stage installed in front (downward) of the liquid crystal display device is moved up and down to change the behavior of a ball (game ball; game medium) inside the center accessory (Patent Literature). 2).

JP 2002-233621 A JP 2006-51136 A

  It is possible to expand display contents by providing an auxiliary display device as in Patent Document 1 and to improve interest by providing a drive stage as in Patent Document 2. However, when attention is paid to the rotary drum type display device, the lottery processing result display (notification) function is still being achieved.

  An object of the present invention is to incorporate a ball distribution function (distribution mechanism) into a rotating drum type display device, thereby making it possible to produce an unprecedented behavior of a ball and improve the interest of the player. The purpose is to provide pachinko machines.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the pachinko gaming machine of the present invention is
Lottery means for executing lottery processing based on establishment of a predetermined condition;
A cylindrical drum arranged in the game area rotates around the axis, displays a plurality of symbols arranged on its outer peripheral surface, and displays a lottery result by the lottery means by stopping and displaying a predetermined symbol. A rotating drum type display device;
A ball guiding path that is arranged on the front side of the drum and guides and guides the ball introduced from the game area in a predetermined direction,
The outer peripheral surface of the drum is fixedly protruded so as to be integrally rotatable with the drum, and the rotation trajectory of the tip portion as viewed from the axial direction is partially the movement trajectory of the ball moving along the ball guiding path. Overlapping one or more sorting members are formed,
When the sorting member comes into contact with a ball moving along the ball guiding path, the moving direction of the ball is changed, and the sorting member is sorted in a direction different from the traveling direction of the ball that has passed without contact with the sorting member. It is characterized by that.

  In the pachinko gaming machine, a ball that is introduced from the game area and moves (for example, drops) along a ball guiding path (for example, a ball dropping path) is formed on the outer peripheral surface of the drum so as to rotate integrally with the drum. When contacting (for example, a collision) with (for example, a rod-shaped protrusion), the traveling direction (and the path) is changed and sorted. Thus, by incorporating a sorting member as a sorting mechanism into the drum, the rotary drum display device can be newly provided with a ball sorting function in addition to the lottery processing result display function. That is, since the drum with the sorting member can produce a novel behavior of the ball that has not been heretofore, the player's interest can be significantly improved.

  Note that the axis of the drum of the rotary drum type display device is usually installed in the horizontal direction, and a plurality of sorting members are generally arranged radially at predetermined intervals along the circumferential direction on the outer peripheral surface of the horizontal drum. It is. There are cases where a single drum is configured and a case where a plurality of (for example, three) axes are arranged in common, and in the case of three drums, any one of the distributing members (for example, the central drum) It is possible to select between only one and a plurality (for example, left and right drums). However, the axis of the drum may be installed not only in the horizontal direction but also in the vertical direction.

Specifically, as the first aspect,
The sorting member is composed of a rod-like protrusion that protrudes in the normal direction from the outer peripheral surface of the drum,
The ball guide passage intersects the axis of the drum as viewed from the front side, and is disposed along the rotation trajectory of the protrusion,
When the drum rotates, the protrusion moves into the ball guiding path, so that when the ball contacts the ball moving along the ball guiding path, the projecting direction of the ball is changed so that it does not contact the protruding object. The ball may be distributed in a direction different from the traveling direction of the passed ball.

  In this way, when the drum-shaped protrusion contacts the ball moving along the ball guide path during the rotation of the drum, the ball can be ejected and the direction of travel can be changed. Becomes obvious at a glance. Therefore, for example, when guiding a ball that has passed through the ball guiding path without being in contact with the protrusion to the winning opening, it is possible to impart a sorting function rich in speed. In addition, when the axis line of the drum is installed in the horizontal direction, the ball guiding path is formed as a ball dropping path installed in the vertical direction, and the balls introduced from the game area can be freely dropped in the ball dropping path.

As a second aspect,
The sorting member is composed of a rod-like protrusion that protrudes in the normal direction from the outer peripheral surface of the drum,
The ball guide passage is disposed along the axis of the drum as viewed from the front side and intersecting the rotation locus of the protrusion,
When the drum rotates, the protrusion moves into the ball guiding path, so that when the ball contacts the ball moving along the ball guiding path, the projecting direction of the ball is changed so that it does not contact the protruding object. The ball may be distributed in a direction different from the traveling direction of the passed ball.

  In this way, when the drum-shaped protrusion contacts the ball moving along the ball guide path during the rotation of the drum, the ball can be ejected and the direction of travel can be changed. Becomes obvious at a glance. Therefore, for example, when guiding a ball that has passed through the ball guiding path without being in contact with the protrusion to the winning opening, it is possible to impart a sorting function rich in speed. In addition, when the axis line of the drum is installed in the horizontal direction, the ball guiding path is formed as a ball rolling path installed in the horizontal direction, and the balls introduced from the game area can be rolled and moved in the ball rolling path.

In these pachinko machines,
When the drum stops, the protrusion can come into contact with all the balls moving along the ball guiding path by stopping at the position where the tip of the protrusion intersects the movement trajectory of the ball,
During the rotation of the drum, the protrusion can be brought into contact with a part of the balls moving along the ball guide path by passing through the position where the tip portion intersects the movement trajectory of the ball.

  In this way, by providing a difference in the distribution function between when the drum is stopped and when the drum is rotating, it is possible to incorporate a variety of distribution functions by utilizing the change between the drum change display and the stop display.

  Specifically, the ball moving along the ball guiding path is returned to the game area when it comes into contact with the tip of the protrusion, and is led out to the winning opening when it passes through the tip of the protrusion without contacting it. Guided in (direction). In this way, it becomes relatively difficult to win a prize opening when the drum is stopped, but the possibility of winning becomes large when the drum is rotating, so that the player can play balls even while the drum is rotating (while the fluctuation is displayed). By continuing to fire, the operating rate of pachinko machines can be improved. Furthermore, if this winning opening is set to another starting winning opening that can be independently held separately from the starting winning opening provided in the gaming area, even if the holding for the starting winning opening in the gaming area becomes full, Since the player can continue to play for the purpose of holding the other start winning slots, the operating rate of the pachinko gaming machine is improved.

  In addition, a plurality of drums (for example, three) are arranged with a common axis, and a rod-shaped protrusion can be formed only on the drum (for example, the central drum) that stops and displays the last. As a result, the drum having the rod-shaped protrusion rotates for a long time compared to the other drums, so that the ball can fall in the ball drop passage before the stop indication (rotation stop) is completed (that is, during rotation). , It can be easily derived to a winning opening without changing the traveling direction of the balls. In addition, since the notification (stop display) of the lottery processing result and the sorting of the balls moving along the ball guidance path are performed synchronously in close proximity, further enhancement of interest can be achieved. It should be noted that the “drum to stop and display at the end” mentioned here is not necessarily required to “always stop at the end in any gaming state”. In particular, if the drum often stops at the end when stopping without reaching reach, the object of the present invention can be achieved.

Furthermore, as a third aspect,
The sorting member is composed of a plate-like protrusion that protrudes in the normal direction with a predetermined width in the axial direction from the outer peripheral surface of the drum,
The ball guide passage is disposed along the axis of the drum as viewed from the front side and intersecting the rotation locus of the protrusion,
When the drum stops, the projecting part forms a part of the ball guiding path by the tip part entering the ball guiding path and stops, and when the ball moving along the ball guiding path is received, There is a case where the traveling direction of the ball is changed and the ball is distributed in a direction different from the traveling direction of the ball that has passed without being received by the protrusion.

  In this way, when the drum is stopped, the plate-like projection can receive the ball moving along the ball guiding path and change the traveling direction, so it is obvious at a glance how the ball passed without being received by the projection It becomes. Therefore, for example, when a ball received by a protrusion is guided to a winning opening, a thrilling sorting function can be provided. In addition, when the axis of the drum is installed in the horizontal direction, a plate-like protrusion can be installed in the horizontal direction to provide a ball rolling path for the balls introduced from the game area to move horizontally while rolling. .

As a fourth aspect,
The sorting member is composed of a box-like protrusion that protrudes in the normal direction with a predetermined width in the axial direction from the outer peripheral surface of the drum,
The ball guide passage intersects the axis of the drum as viewed from the front side, and is disposed along the rotation trajectory of the protrusion,
When the drum stops, the projecting body receives the ball moving along the ball guide passage by stopping the tip portion of the projection entering the ball guide passage, and then changes the traveling direction of the ball when the drum rotates. In other words, the ball may be distributed in a direction different from the traveling direction of the ball that has passed without being received by the protrusion.

  In this way, when the drum is stopped, the box-shaped protrusion receives the ball moving along the ball guide passage, and the traveling direction can be changed by the subsequent rotation, so that the ball passed without being received by the protrusion This sort of distribution becomes obvious at a glance. Therefore, for example, when a ball received by a protrusion is guided to a winning opening, a thrilling sorting function can be provided. When the axis of the drum is installed horizontally, a box-shaped projection is opened upward, and the ball introduced from the game area is received when the drum is stopped. The ball can be released.

In these pachinko machines,
When the drum stops, the protrusion can stop all the balls moving along the ball guide path by stopping at the position where the tip of the protrusion intersects the ball movement trajectory,
When the drum rotates, the protrusion can receive a part of the balls moving along the ball guide path by passing through the position where the tip portion intersects the ball movement locus.

  In this way, by providing a difference in the distribution function between when the drum is stopped and when the drum is rotating, it is possible to incorporate a variety of distribution functions by utilizing the change between the drum change display and the stop display.

  Specifically, the ball moving along the ball guiding path is led out to the winning opening when received by the protrusion, and returned to the game area when passing without being received by the protrusion, leading to a different path (direction). Are distributed. For example, if this winning opening is set as a starting winning opening, the possibility of winning in the starting winning opening increases when the drum is stopped, while winning becomes relatively difficult when the drum rotates. Therefore, for players who are difficult to win even if they hit a ball aiming at the start prize opening provided in the game area like a beginner, other start prize openings that are easy to win especially when the drum is stopped are provided. Can be rescued.

(Example 1)
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is a schematic front view showing an example of a pachinko gaming machine according to the present invention, FIG. 2 is a front view showing a first example of a center accessory including a rotary drum type display device, and FIG. 3 is X1-X1 in FIG. 4 is a perspective view of FIG. A pachinko gaming machine 1 shown in FIG. 1 has a game board 3 that is disposed inside a frame and covered by a glass door 2 (see FIG. 3). A circular game area 3 a is formed on the game board 3. A ball supply tray 4 is provided below the game area 3a. A ball (game ball; game medium) prepared in the ball supply tray 4 is launched toward the game area 3a by a launching device 110 (see FIG. 5) including the handle 5. Since a large number of nails 3b are erected in the game area 3a, balls that have reached the game area 3a of the game board 3 through rails (not shown) fall through the game area 3a while being hit by the nails 3b. Reference numeral 102 denotes a speaker, and 103 denotes decorative lamps (see FIG. 5).

  A center accessory 10 is disposed near the center of the game area 3a. The center accessory 10 includes a rotary drum type display device (hereinafter also simply referred to as a display device) 20 disposed behind the center portion of the game board 3, an upper stage 30 disposed above the display device 20, and a display device. 20, a lower stage 40 disposed below 20, and a ball drop passage 50 (ball guide passage) disposed on the front side of the display device 20. The display device 20 displays the success / failure determination result of the jackpot lottery (internal lottery) executed based on the establishment of a predetermined condition as a special symbol (special symbol), and then stops and displays it to notify the player. Above the upper stage 30, a first special figure holding display unit 21 composed of a plurality of (for example, four) LEDs positioned in a horizontal row is arranged. In FIG. 1, the flow direction of the balls is the vertical direction, the crossing direction is the horizontal direction, and the side where the player is located with respect to the game board 3 (the front side of the page) is called the front side.

  An electric tulip (hereinafter also referred to as an electric chew) 12 (first start winning opening; start chucker) having a pair of rotating blade pieces 12a and 12a that are opened and closed is disposed below the center accessory 10. Below the electric chew 12 is provided a big winning device 13 (variable winning device; attacker) that is opened when a big hit is made in the big win lottery executed based on the winning of the electric chew 12. In addition, a passage gate 11 (through chucker) for opening the electric chew 12 for a predetermined time and number of times (for example, once in 0.5 seconds) is arranged on the left side of the center accessory 10. Has been. Reference numeral 14 denotes a ball outlet for collecting balls.

  In the diagonally lower left part of the center object 10 (below the passage gate 11), there are a normal map display unit 15 for displaying a normal symbol (normal map) by one or a plurality of (for example, one) LEDs, and a plurality (for example, four). ) And a general-purpose hold display unit 16 made up of LEDs. In this general-purpose display section 15, the LED is displayed blinking according to the result of the winning lottery performed when the ball passes the passing gate 11 (the fluctuation time is 30 seconds in the normal state, 2 seconds in the short time state or the probability variation state). ) To display the change in the usual figure, then turn on the display when winning and turn off the display when lost. When the winning lottery result is a win, the rotating blade pieces 12a, 12a are opened for a short time (for example, 0.5 seconds) in the normal state, and the rotating blade pieces 12a, 12a are opened in the short-time state or the probable state. Since the game is opened for a long time (for example, 5 seconds), the winning rate to the electric chew 12 is higher in the short-time state and the probability-changed state than in the normal state, and the game can be continued without reducing the number of balls.

  The normal winning probability is set to 1/100 in the normal state and 99/100 in the short-time state and the probability variation state. Therefore, the rotating blade in the electric Chu 12 is shorter in the short-time state and the certain variation state than in the normal state. The opening frequency of the pieces 12a and 12a is increased.

  Further, when the ball passes through the passing gate 11 during the fluctuation display on the general map display unit 15 or during the opening operation of the rotary blades 12a, 12a, the result of the winning lottery performed based on the passing of the ball Is temporarily stored (suspended), and one LED of the ordinary map display unit 16 is turned on. Up to four winning lottery results can be held, and after the change display in the previous general-purpose display unit 15 and the opening operation of the rotary wing pieces 12a, 12a are finished, they are read out in the order in which they are held. The variable display on the general map display unit 15 is started.

  As shown in FIG. 2, the display device 20 includes a plurality of (for example, three) cylindrical drums 20 </ b> L, 20 </ b> C, and 20 </ b> R parallel to the game board 3 (see FIG. 1) on an axis O that extends in the left-right direction. It is arranged in a line along. Each of the left, middle, and right drums 20L, 20C, and 20R has a plurality of symbols (for example, Arabic numerals 1 to 8) arranged on the outer peripheral surface thereof, and stepping motors for the left, middle, and right drums ( Hereinafter, it is connected to output shafts (not shown) of 23L, 23C, and 23R (see FIG. 5) and rotates around the axis O. The display device 20 displays three rows of symbols (for example, three-digit Arabic numerals) on the upper and lower rows or the third row to display a lottery result to the player (design display area). Is formed. Award balls (for example, 5 balls) are paid out in accordance with the winning of the electric Chu 12 (see FIG. 1), and the three drums 20L, 20C, 20R are respectively rotated around the axis O by the drum motors 23L, 23C, 23R. After rotating and displaying a plurality of symbols at the same time, a predetermined special figure is stopped and displayed on the display window 20a in the order of the left drum 20L, the right drum 20R, and the middle drum 20C, thereby informing the lottery result (whether or not determination result). .

  L1 to L5 indicate effective lines for determining whether or not the display window 20a is correct. A big hit when three of the same Arabic numerals are aligned on any one of the upper horizontal line L1, the central horizontal line L2, the lower horizontal line L3, the diagonally upward right line L4, and the diagonally downward right line L5 (for example, a doublet such as “777”). When two lines are aligned, reach is reached, and any line is not aligned (for example, “345” or the like), resulting in a loss. In addition, when reaching on any one of the effective lines L1 to L5, it is referred to as single reach, and when reaching on two or more effective lines, it is referred to as double reach.

  In addition, when the ball passes the electric Chu 12 (see FIG. 1) during the variable display or the big hit on the display device 20, the determination result of the big hit lottery performed based on the passage of the ball is temporarily stored ( 1 LED on the special figure hold display section 21 is lit. It is possible to hold a maximum of four jackpot lottery results, and after the variable display and jackpot on the previous display device 20 are finished, the display device 20 starts to display a new special map variable display in the order in which it was held. To do.

  As shown in FIGS. 2 and 3, the upper stage 30 has a warp inlet 31a (introduction port) that opens to the game area 3a side and a warp outlet 31b (opening) that opens to the inside of the center accessory 10. A warp route 31 communicating with the game area 3a is disposed at both left and right ends, and a drop opening 32 for dropping the introduced ball B is formed at the center in the left-right direction. The lower stage 40 is formed with a start port 41 (second start winning port; start chucker) for starting the big win lottery by winning directly below the drop port 32, and a discharge port for returning the ball B to the game area 3a. 42 is formed on each of the left and right sides.

  The ball drop passage 50 is located on the front side of the middle drum 20C to be stopped and displayed last, and allows the ball B introduced from the game area 3a to freely fall in the vertical direction from the drop port 32 of the upper stage 30 (guidance guidance). It constitutes a passage for. Also, the outer peripheral surface of the intermediate drum 20C is fixed to and protrudes from the outer peripheral surface, and the rotation trajectory K1 of the tip portion as viewed from the direction of the axis O falls (moves) along the ball dropping passage 50. A plurality of (for example, eight) rod-like protrusions 25 (sorting members; sorting mechanisms) that partially overlap the movement locus K2 are formed.

  Specifically, the rod-shaped protrusion 25 has, for example, an elliptical cross section, and protrudes radially (in the normal direction) from the outer peripheral surface of the intermediate drum 20C along the circumferential direction at a predetermined interval (for example, 45 ° interval). On the other hand, the ball drop passage 50 (ball movement trajectory K2) intersects (for example, is orthogonal to) the axis O of the middle drum 20C when viewed from the front side, and is disposed along the tip end rotation trajectory K1 of the rod-shaped protrusion 25. ing.

  The ball drop passage 50 includes a passage cover plate 51 disposed between the glass door 2 and each drum 20L, 20C, 20R (display device 20), a passage cover plate 51, and each drum 20L, 20C, 20R (display device). 20) and a passage forming plate 52 disposed between the two. The passage cover plate 51 and the passage formation plate 52 are positioned in parallel, and both are made of a light-transmitting material (for example, a transparent or translucent synthetic resin material). In addition, a notch 52a for allowing the tip portion (tip portion rotation locus K1) of the rod-like protrusion 25 to pass through is formed in the intermediate portion in the left-right direction of the passage forming plate 52. Therefore, when the diameter of the ball B is D, the width of the left and right opening of the notch 52a is W, and the short diameter of the rod-shaped protrusion 25 is d, the relationship is D> W> d.

  As shown in FIG. 4, the ball B introduced from the game area 3 a (see FIG. 1) into the center object 10 through the warp route 31 moves through the ball drop passage 50 from the drop port 32 of the upper stage 30. It falls freely along the locus K2 and reaches the lower stage 40. At this time, when the rod-like protrusion 25 that can rotate integrally with the middle drum 20C collides (contacts) with the ball B that falls along the ball drop passage 50 (ball movement trajectory K2), the traveling direction of the ball B is changed to be a rod shape. The balls B are distributed in a direction different from the traveling direction of the balls B that have passed without colliding with the protrusions 25.

  Specifically, when the middle drum 20C is stopped, the tip of the rod-like protrusion 25 is stopped at a position where it intersects the ball movement locus K2, so that it falls along the ball drop passage 50 (ball movement locus K2). All the balls B collide with the rod-like protrusions 25, and their traveling direction and path are changed and returned to the game area 3a (see FIG. 1) from either the left or right discharge port 42. When the middle drum 20C is rotated (the rotation direction is counterclockwise in FIG. 3, that is, the direction in which the symbol fluctuates from the top to the bottom when viewed from the front), the tip of the rod-shaped protrusion 25 is moved to the ball drop passage 50. It rushes in (passes the position that intersects the ball movement locus K2). At this time, a part of the ball B moving along the ball drop path 50 (ball movement path K2) collides with the rod-like protrusion 25, and from the discharge port 42 to the game area 3a (see FIG. 1) in the same manner as when stopped. Returned. On the other hand, since the remaining balls B pass without colliding with the rod-shaped protrusions 25, they are led out to the start port 41 located directly below the ball drop passage 50 (ball movement locus K2), and the second start winning detector 141 is obtained. (See FIG. 3). In the lower stage 40, a second special figure holding display unit 22 composed of a plurality of (for example, four) LEDs positioned in a horizontal row is arranged.

  Further, when the ball B passes through the start port 41 during the fluctuation display or the big hit on the display device 20, the determination result of the jackpot lottery performed based on the passage of the ball B is temporarily stored (held). One LED of the second special figure hold display unit 22 is lit. It is possible to hold a maximum of four jackpot lottery results, and after the variable display and jackpot on the previous display device 20 are finished, the display device 20 starts to display a new special map variable display in the order in which it was held. To do. However, when both the electric Chu 12 (first special figure hold display part 21) and the start opening 41 (second special figure hold display part 22) are held (lighted), the start opening 41 (second special figure hold) Prioritize digestion (lighting) of the display unit 22).

  The main circuit 120 includes an electric chew solenoid 115 that opens and closes the rotary blades 12a and 12a of the electric chew 12, a big winning solenoid 116 that opens and closes the big winning device 13, the LED of the first special figure holding display unit 21, the second special The LED of the figure hold display unit 22, the LED of the general figure display unit 15, and the LED of the general figure hold display unit 16 are respectively driven and controlled.

  Next, with reference to FIG. 1, an outline of the flow of the game in the pachinko gaming machine 1 (change of the game state on the game board 3) will be described.

  In a normal state, when a ball enters the passing gate 11 and is detected by the gate passing detector 111, a normal drawing lottery (a value is extracted from a random number counter for normal drawing) is executed, and the lottery result is displayed as a normal drawing. Stored as pending. The lottery result of the winning lottery is determined using a normal hit determination table (general drawing winning probability: 1/100), and the lottery result is displayed on the general drawing display unit 15 according to the determination result (the variation time is 30). Seconds). If the winning lottery result is winning, the LED of the general-purpose display unit 15 is turned on and the electric chew solenoid 115 is excited to open the rotary blade pieces 12a and 12a for a predetermined time (0.5 seconds). , Make it easy to win the electric Chu 12.

  When the ball wins the electric Chu 12 and is detected by the first start winning detector 112, the starting condition is satisfied, a predetermined number of winning balls (for example, five per winning) are paid out, and a jackpot lottery (a special figure random number) The value is extracted from the counter) and the lottery result is stored as a special figure hold. The lottery result of the jackpot lottery is determined using the normal / short-time jackpot determination table (special drawing winning probability: 1/250), and the symbol variation corresponding to the determination result is started on the display device 20. In the display device 20, the left, middle, and right drums 20L, 20C, and 20R are variably displayed over a predetermined time, and are confirmed and displayed (stop display) in the order of the left drum 20L, the right drum 20R, and the middle drum 20C. If the determination result is a big hit, a three-digit big hit symbol (for example, a doublet such as “777”) is fixedly displayed on one of the effective lines L1 to L5, and if the determination result is a loss, a three-digit lost symbol (for example, “345” etc. are displayed on all the effective lines L1 to L5.

  When the jackpot symbol is stopped and displayed on the display device 20 (left, middle, right drums 20L, 20C, 20R), the jackpot state (special game state) is entered, and the grand prize winning device 13 is excited by exciting the big winning solenoid 116. It opens and brings the situation where balls are very easy to enter. After the winning device 13 is opened, a predetermined number (for example, 10) of winning detection by the winning device detector 113 or a lapse of a predetermined time (for example, 25 seconds) is regarded as one round, and the large winning solenoid 116 is de-energized. Is closed. Since one big hit state is repeated up to a predetermined number of rounds (for example, 15 times), the player can obtain a large number of winning balls (for example, 15 pieces per winning) during the big hit state.

  After the jackpot in the normal state, the probability change state (high probability state; probability change is in progress) at a rate of 60%. That is, after a big hit with an odd jackpot symbol (probability variation symbol), it becomes a probable variation state and continues until the next jackpot. On the other hand, after a big jackpot with an even number of jackpot symbols (non-probable variation), it becomes a short-running state and continues until the next jackpot occurs or the special figure is displayed 100 times, or one of them is established. .

  In the probabilistic state, the fluctuation time of the usual figure is shortened (ordinary figure fluctuation time: 2 seconds), the winning probability of the ordinary figure is increased (the ordinary figure winning probability: 99/100), and the rotating blade pieces 12a, 12a As the opening time becomes longer (5 seconds), the jackpot determination table for probability variation (special map winning probability: 1/25) having a higher jackpot winning probability than the normal jackpot determination table (special map winning probability: 1/250) ) To determine whether or not it is correct. That is, in the probability variation state, winning in the electric Chu 12 is facilitated, so that it is possible to play without reducing the number of holding balls and to win the next jackpot immediately.

  In the short-time state, the fluctuation time of the usual figure is shortened similarly to the probability variation state, the winning probability of the ordinary figure is increased, the opening time of the rotary blade pieces 12a, 12a is increased, and a normal jackpot determination table (special feature) The winning / no-go determination is made according to the figure winning probability: 1/250). That is, even in a short time state, it is easy to win the electric Chu 12, so that the game can be played without reducing the number of holding balls so much. If a new jackpot is not won, the variable display of the special figure is repeated, and when the time-short state ends, the state shifts to the normal state.

  By the way, regardless of whether the game state is the normal state, the probability variation state, or the short-time state, when the ball B is introduced from the game area 3a through the warp route 31 into the center accessory 10, the ball B freely falls along the ball movement path K2 through the ball drop path 50 from the drop port 32 of the upper stage 30. At this time, if the middle drum 20C is stopped, the tip of the rod-shaped protrusion 25 is stopped at a position that intersects the ball movement locus K2, so that the ball B collides with the rod-shaped protrusion 25 and is left or right. Reaches the outlet 42 and is returned to the game area 3a. On the other hand, when the middle drum 20C is rotating, a part of the balls B can pass without colliding with the rod-like protrusions 25, so that the start opening 41 located immediately below the ball drop passage 50 (the ball movement locus K2). The second start winning prize detector 141 is detected.

  Thus, since the rod-like protrusion 25 is provided on the drum 20C during the last stop display (that is, it rotates for a long time compared to other drums), the ball B is present before the stop display (ie during rotation). The ball drop passage 50 can be dropped. That is, the probability that the ball B collides with the rod-shaped protrusion 25 and changes the traveling direction is small, and the probability that the ball B enters the start port 41 is large. Note that, when the ball B wins the start opening 41, the jackpot lottery, determination of success / failure, change display of special figure, stop display, and the like are performed in the same manner as when winning the electric Chu 12. However, the hold (lighting) of the start port 41 (second special figure hold display unit 22) is performed independently from the hold (lighting) of the electric chew 12 (first special figure hold display unit 21), the former being the latter Is prioritized (digested first). Therefore, the player can continue to hit the ball toward the start port 41 even when the number of hold (lights) of the electric Chu 12 (first special figure hold display unit 21) has reached four, the pachinko gaming machine 1 The operating rate of the system will also improve.

  Next, the distribution control in the pachinko gaming machine 1 will be described with reference to the flowcharts shown in FIGS. In the subsequent flowcharts, the jackpot flag indicates a variable representing the jackpot determination result. At the start of the control program, the jackpot flag is initialized to the OFF state (the jackpot determination result is lost).

  FIG. 6 shows a flowchart of the first start winning detection process. When the first start winning detector 112 attached to the electric Chu 12 detects the passing of the ball, a detection signal is transmitted to the main circuit 120. When the main circuit 120 receives the detection signal from the first start winning detector 112 (S1: YES), the main circuit 120 determines whether or not the number of the first special figure hold has reached four (S2). Note that the first special figure hold is temporarily stored in a predetermined area of the RAM 123 of the main circuit 120. When the main circuit 120 determines that the number of the first special figure hold is 3 or less (S2: NO), the main circuit 120 extracts the value from the special figure random number counter and performs the big hit lottery (S3), and the lottery result is displayed as the first special figure. The figure is stored in a predetermined area of the RAM 123 (S4), a prize ball payout instruction is issued (S5), and the first start winning detection process is terminated. When no detection signal is received from the first start winning detector 112 (S1: NO), the first start winning detection process is immediately terminated. When the number of first special figure holds has reached four (S2: YES), a prize ball payout instruction is issued (S5), and the first start winning detection process is terminated.

  Next, FIG. 7 shows a flowchart of the second start winning detection process. When the second start winning detector 141 attached to the start port 41 detects the passage of the ball, a detection signal is transmitted to the main circuit 120. When the main circuit 120 receives the detection signal from the second start winning detector 141 (S11: YES), the main circuit 120 determines whether or not the number of second special figure reservations has reached four (S12). Note that the second special figure hold is temporarily stored in a predetermined area of the RAM 123 of the main circuit 120. When the main circuit 120 determines that the number of second special figure reservations is three or less (S12: NO), the main circuit 120 extracts a value from the special figure random number counter and performs a jackpot lottery (S13). The figure is stored in a predetermined area of the RAM 123 (S14), a prize ball payout instruction is issued (S15), and the second start winning prize detection process is terminated. When the detection signal is not received from the second start winning detector 141 (S11: NO), the second start winning detection process is immediately terminated. When the number of second special figure hold has reached four (S12: YES), a prize ball payout instruction is issued (S15), and the second start winning detection process is terminated.

  Next, FIG. 8 shows a flowchart of the variable display pre-processing following FIG. The main circuit 120 determines whether or not the jackpot is being hit (S21), and when it is determined that the jackpot is not being hit (S21: NO), the main circuit 120 determines whether or not the display device 20 is displaying a special figure (S22). ). When it is determined that the variable display is not being performed (S22: NO), it is confirmed whether there is a second special figure hold in a predetermined area of the RAM 123 (S23), and if there is a second special figure hold (S23: YES), the second The special figure hold is read (S24). On the other hand, if there is no second special figure hold (S23: NO), it is confirmed whether there is a first special figure hold in a predetermined area of the RAM 123 (S25). If there is a first special figure hold (S25: YES), The first special figure hold is read (S26).

  Further, the main circuit 120 makes a jackpot determination (whether or not) using the determination table for the second special figure hold read in S24 or the first special figure hold read in S26. Specifically, it is determined whether or not the value recorded in the probability variation determination table matches each special figure hold value (S27). Based on the determination result, the main circuit 120 determines the special symbol stop pattern and the variation time on the display device 20 (S28), executes the special diagram variation processing (S29), and performs the variation display pre-processing. finish. When it is determined that the jackpot is being hit (S21: YES), when it is determined that the fluctuation of the special figure is being displayed (S22: YES), neither the second special figure hold nor the first special figure hold is present. Sometimes (S23: NO; S25: NO), the pre-process for variation display is immediately terminated.

  Next, FIG. 9 shows a flowchart of the special figure variation processing subroutine of FIG. In the special figure fluctuation process (S29) shown in FIG. 9, the main circuit 120 starts the fluctuation timer, starts the fluctuation of the special figure on the display device 20 (S291), and stops the special figure on the display device 20. The sub-control circuit 101 is notified of the symbol and the variation time (S292). Thereafter, the main circuit 120 waits for a predetermined time (fluctuation time) to elapse (S293: YES), and instructs the sub-control circuit 101 to end the change of the special figure (stop display) (S294). Subsequently, the main circuit 120 determines whether or not the jackpot determination result (special drawing lottery result) is a jackpot (S295). If it is a jackpot (S295: YES), the jackpot flag is turned ON (S296). The special figure variation process is terminated. If it is not a big hit (S295: NO), the special figure variation process is terminated as it is.

  In this way, when the ball B introduced from the game area 3a and falling along the ball drop passage 50 collides with the rod-shaped protrusion 25 that is formed on the outer peripheral surface of the middle drum 20C and can rotate integrally with the middle drum 20C, The balls B are sorted by changing the traveling direction (and the course). By incorporating the rod-shaped protrusion 25 serving as a sorting mechanism into the middle drum 20C, the rotary drum display device 20 can be newly provided with a ball B sorting function in addition to the lottery processing result display function. That is, the middle drum 20 </ b> C with the rod-like protrusions 25 can produce a novel behavior of the ball B that has not been heretofore, and can greatly improve the interest of the player.

  Moreover, when the rod-like protrusion 25 collides with the ball B that freely falls along the ball drop passage 50 when the middle drum 20C rotates, the ball B can be ejected and the traveling direction can be changed, so that it passes without colliding. The distribution with the ball B becomes obvious at a glance. Therefore, for example, by guiding the ball B that has passed through the ball drop passage 50 without colliding with the rod-shaped protrusion 25 to the start port 41, a sorting function rich in speed can be provided.

  Note that if the probability that the ball B that freely falls along the ball drop passage 50 during the rotation of the middle drum 20C wins the start opening 41 is set to about 50%, the interest of the player can be further improved. For example, when the drop distance of the ball B that freely falls along the ball drop passage 50 ≈ the separation distance between the drop opening 32 and the start opening 41 ≈ the length of the ball movement locus K2 ≈ 10 cm, the start opening 41 from the drop opening 32 The arrival time (required time) is about 0.14 seconds (about 0.1 seconds in the first half and about 0.04 seconds in the second half). When a stepping motor of 240 steps / second is adopted as the middle drum motor 23C and rotation control is performed at 2 milliseconds / step, the rotation speed is 0.48 seconds / rotation. Therefore, when there are 8 symbols (Arabic numerals 1 to 8) on the outer peripheral surface of the intermediate drum 20C, the rotation is performed at 0.06 seconds per symbol (45 °). Therefore, the rotation speed of the intermediate drum 20C is calculated such that a predetermined percentage (for example, 50%) of the balls B freely falling along the ball dropping passage 50 can pass without colliding with the rod-shaped protrusions 25. By using a stepping motor that matches the rotational speed, the distribution ratio of the balls B can be adjusted.

(Example 2)
10 is a front view showing a second example of a center accessory including a rotary drum type display device, FIG. 11 is a cross-sectional view taken along the line X2-X2 of FIG. 10, and FIG. 12 is a perspective explanatory view of FIG. The center accessory 210 shown in this embodiment includes a rotary drum type display device (hereinafter also simply referred to as a display device) 20 disposed behind the center of the game board 3 and a lower stage disposed below the display device 20. 240 and a ball rolling passage 250 (ball guide passage) disposed on the front side of the display device 20, and has a different configuration from the center accessory shown in the first embodiment (FIGS. 2 to 4). ing.

  The ball rolling passage 250 is located across the front side of the left, middle, and right drums 20L, 20C, and 20R, and rolls the ball B introduced from the game area 3a from left to right (guidance guidance). An inclined bowl-shaped passage is formed. As shown in FIG. 11, the movement trajectory K2 (see FIG. 12) of the ball B that rolls (moves) along the ball rolling passage 250 is a rod-shaped protrusion 25 (see FIG. 12) that protrudes from the outer peripheral surface of the middle drum 20C. (Distributing member; distributing mechanism) is arranged so as to partially overlap with the rotation locus K1 of the tip portion. Further, as shown in FIG. 10, the ball rolling passage 250 (ball movement trajectory K2) is substantially along the common axis O of each of the drums 20L, 20C, 20R, and the tip portion rotation trajectory K1 of the rod-shaped protrusion 25. They are arranged so as to intersect (for example, orthogonally).

  More specifically, as shown in FIG. 12, a concave groove 250a for stably rolling the ball B is formed on the upper surface (ball placement surface) of the ball rolling passage 250 over the entire length. . Then, as shown in FIG. 11, the tip of the rod-shaped protrusion 25 intersects with the ball movement locus K2, collides with the ball B moving along the ball movement locus K2, and is dropped from the ball rolling passage 250. As can be seen, when the diameter of the ball B is D and the width of the ball rolling passage 250 is w, the relationship is D> w. In this embodiment, a partition plate such as the passage cover plate 51 (see FIG. 3) of the first embodiment is not provided between the glass door 2 and the passage forming plate 52.

  Since the ball rolling passage 250 is provided, the warp route 31 is disposed on the left side wall portion of the center accessory 210, and the warp inlet 31 a (introduction port) that opens to the game area 3 a side and the ball rolling passage 250. It has a warp outlet 31b (opening) that opens at the start end (left end) and communicates with the game area 3a. The start opening 41 (second start winning opening; start chucker) is disposed on the right side wall portion of the center accessory 210 that becomes the end portion (right end portion) of the ball rolling passage 250. Therefore, only a rolling surface for returning the ball B to the game area 3a is formed on the lower stage 240.

  As shown in FIG. 12, the ball B introduced from the game area 3a (see FIG. 11) through the warp route 31 into the center accessory 10 is left on the ball rolling path 250 along the ball movement path K2. Roll from to right. At this time, when the rod-like protrusion 25 that can rotate integrally with the middle drum 20C collides (contacts) with the ball B that rolls along the ball rolling path 250 (ball movement locus K2), the traveling direction of the ball B is changed. The balls B are distributed in a direction different from the traveling direction of the balls B that have passed without colliding with the rod-shaped protrusions 25.

  Specifically, when the middle drum 20C is stopped, if the tip of the rod-shaped protrusion 25 stops at a position where it intersects the ball movement locus K2, the ball rolling path 250 (ball movement locus K2) rolls. All the balls B that move collide with the rod-shaped protrusions 25, and their traveling direction and path are changed and returned to the game area 3a (see FIG. 11) via the rolling surface of the lower stage 240 or directly. When the intermediate drum 20C rotates (the rotation direction is clockwise in FIG. 11, that is, the direction in which the symbol fluctuates from the bottom to the top as viewed from the front), the tip of the rod-shaped protrusion 25 intersects the ball movement locus K2. Pass through the position to be. At this time, a part of the ball B that rolls along the ball rolling path 250 (ball movement path K2) collides with the rod-shaped protrusion 25 and is returned to the game area 3a (see FIG. 11) in the same manner as when stopped. . On the other hand, since the remaining balls B pass without colliding with the rod-like protrusions 25, they are led out to the starting port 41 located at the end of the ball rolling passage 250 (ball movement locus K2), and the second starting winning detector. 141 (see FIG. 10).

(Example 3)
13 is a front view showing a third example of a center accessory including a rotating drum type display device, FIG. 14 is a sectional view taken along the line X3-X3 of FIG. 13, and FIG. 15 is a perspective explanatory view of FIG. The center accessory 310 shown in this embodiment includes a rotary drum type display device (hereinafter also simply referred to as a display device) 20 disposed behind the center of the game board 3 and a lower stage disposed below the display device 20. 340 and a ball drop passage 350 (ball guide passage) disposed on the front side of the display device 20, and have a configuration different from the center accessory shown in the second embodiment (FIGS. 10 to 12). Yes.

  The ball drop passage 350 is a space located on the front side of the left drum 20L and / or the front side of the right drum 20R and surrounded by the passage cover plate 51. The ball drop passage 350 receives the ball B introduced from the game area 3a and is closer to the center. It includes a plate-shaped passage for rolling (guidance guidance) to the (inner drum 20C side). Therefore, the outer peripheral surface of the left drum 20L and / or the right drum 20R protrudes while being fixed to the outer peripheral surface, and the rotation locus K1 of the tip portion viewed from the direction of the axis O (see FIG. 2) is a ball drop passage. Plural (for example, four) plate-like protrusions 325 (sorting members; sorting mechanisms) that partially overlap the movement trajectory K2 of the ball B falling (moving) along 350 are formed.

  Specifically, the plate-like protrusions 325 project radially (in the normal direction) from the outer peripheral surface of the left drum 20L and / or the right drum 20R along the circumferential direction at a predetermined interval (for example, 90 ° interval). When the left drum 20L and / or the right drum 20R are stopped, the plate-like protrusions 325 are positioned horizontally along the axis O (see FIG. 2) and protrude from the outer peripheral surfaces of these drums 20L and 20R. In some cases, the tip of the protrusion 325 enters the ball drop passage 350 and constitutes a part of the ball drop passage 350 (ball movement locus K2). A concave groove 325a (see FIG. 15) for stably guiding the ball B to the central portion in the left-right direction is formed on the upper surface (ball placement surface) of the plate-like protrusion 325 over the entire length.

  Note that the warp route 31 is disposed on both the left and right wall portions of the center accessory 210, and each warp route 31 is provided at a warp entrance 31a (introduction port) that opens to the game area 3a side and in the vertical center of the display window 20a. It has the warp exit 31b (opening) opened in the form which opposes the plate-shaped protrusion 325 which has stopped, and is connected with the game area | region 3a. The lower stage 340 is formed with a starting port 41 (second starting winning port; start chucker) for starting the big win lottery by winning below the middle drum 20C, and for returning the ball B to the game area 3a. A discharge port 42 is formed on each of the left and right sides.

  As shown in FIG. 15, the ball B introduced from the game area 3 a (see FIG. 14) through the warp route 31 into the center accessory 10 is located at the left and right ends along the ball movement path K <b> 2 on the ball dropping path 350. It is discharged from the part side toward the center. At this time, the plate-like protrusion 325 that can rotate integrally with the left drum 20L and / or the right drum 20R receives (contacts) the ball B falling along the ball drop passage 350 (ball movement locus K2) and the ball B. Is changed to a direction different from the traveling direction of the balls B that have passed without being received by the plate-like protrusions 325.

  Specifically, when the left drum 20L and / or the right drum 20R are stopped, the tip of the plate-like protrusion 325 may stop at a position where it intersects the ball movement locus K2. At this time, all the balls B released (moved) along the ball drop passage 350 (ball movement locus K2) are received by the plate-like protrusions 325, and their traveling direction and path are changed and guided to the central portion. The second start winning detector 141 (see FIG. 13) is led out to the start port 41 on the center side of the lower stage 340. When the plate-like protrusion 325 stops at a position that does not face the warp outlet 31b, the ball B released (moved) along the ball drop passage 350 (ball movement locus K2) is the lower stage 340. It returns to the game area | region 3a (refer FIG. 14) from the discharge port 42 of both ends.

  Further, when the left drum 20L and / or the right drum 20R is rotated (the rotation direction is counterclockwise in FIG. 14, that is, the direction in which the pattern fluctuates from top to bottom as viewed from the front), the tip of the plate-like protrusion 325 is rotated. The part passes the position where it intersects the ball movement locus K2. At this time, a part of the ball B that rolls along the ball drop passage 350 (ball movement trajectory K2) is received by the plate-like protrusion 325 and led to the start port 41. On the other hand, since the remaining balls B pass (fall) without being received by the plate-like protrusions 325, they are returned to the game area 3a (see FIG. 14) from the discharge ports 42 at both ends of the lower stage 340.

Example 4
16 is a front view showing a fourth example of a center accessory including a rotary drum type display device, FIG. 17 is a sectional view taken along the line X4-X4 of FIG. 16, and FIG. 18 is a perspective explanatory view of FIG. The center accessory 410 shown in this embodiment includes a rotary drum type display device (hereinafter also simply referred to as a display device) 20 disposed behind the center of the game board 3 and an upper stage disposed above the display device 20. 30, a lower stage 440 disposed below the display device 20, and a ball drop passage 450 (ball guide passage) disposed on the front side of the display device 20, and Example 3 (FIGS. 13 to 15). It has a configuration different from the center role shown in FIG.

  The ball drop passage 450 is located on the front side of the middle drum 20C and includes a pocket-shaped passage for receiving the ball B introduced from the game area 3a and moving it backward (guided guidance). Therefore, the outer peripheral surface of the intermediate drum 20C is fixed to and protrudes from the outer peripheral surface, and the rotation locus K1 of the tip portion falls along the ball dropping passage 450 when viewed from the direction of the axis O (see FIG. 2) ( A plurality of (for example, eight) box-shaped protrusions 425 (sorting members; sorting mechanisms) that partially overlap the movement locus K2 of the ball B that moves) are formed.

  Specifically, the box-shaped protrusions 425 project radially (normal direction) at a predetermined interval (for example, 45 ° interval) along the circumferential direction from the outer peripheral surface of the intermediate drum 20C, and are visible to the player through the display window 20a. It is installed so that the upper part is open when in position. At the time of rotation and stop of the middle drum 20C, at least any one of the box-like protrusions 425 always enters the ball dropping passage 450.

  A discharge port 42 for returning the ball B to the game area 3a is formed separately on both the left and right sides so that the left and right division positions are shifted slightly to the left from the tip end rotation locus K1 of the box-like projection 425. In addition, as shown in FIG. 17, the ball B released when the box-shaped protrusion 425 passes through the lowest point due to rotation leads to the start opening 41 (second start winning opening; start chucker) that starts the big win lottery by winning. It is burned.

  As shown in FIG. 18, the ball B introduced from the game area 3 a (see FIG. 17) through the warp route 31 into the center accessory 10 moves through the ball drop passage 450 from the drop port 32 of the upper stage 30. It falls freely along the locus K2 and reaches the lower stage 440. At this time, when the box-shaped protrusion 425 that can rotate integrally with the middle drum 20C receives (contacts) the ball B falling along the ball drop passage 450 (ball movement path K2), the traveling direction of the ball B is changed. Then, the balls B are distributed in a direction different from the traveling direction of the balls B that have passed without being received by the box-shaped protrusion 425.

  Specifically, when the middle drum 20C is stopped, the tip of the box-like protrusion 425 stops at a position where it intersects the ball movement locus K2, so that it falls along the ball drop passage 450 (ball movement locus K2). All balls B to be brought into contact with the box-like protrusions 425 and the traveling direction of the balls B are distributed to the left and right. When one of the box-shaped protrusions 425 is stopped at the center in the vertical direction of the display window 20a, the falling ball B is received by the box-shaped protrusion 425. The ball B received by the box-shaped protrusion 425 is changed in its traveling direction and path by the subsequent rotation, and then released from the box-shaped protrusion 425 when it passes through the lowest point and is guided to the start port 41. This is detected by the 2-start winning prize detector 141 (see FIG. 17).

  When the middle drum 20C is rotated (the rotation direction is counterclockwise in FIG. 17, that is, the direction in which the symbol fluctuates from the top to the bottom as viewed from the front), the tip of the box-shaped protrusion 425 moves the ball movement locus K2. Passes through the intersection with At this time, a part of the ball B falling along the ball dropping path 450 (ball movement locus K2) is received by the box-shaped protrusion 425 and led out to the start port 41 in the same manner as when stopped. On the other hand, since the remaining balls B pass without being received by the box-shaped protrusions 425, they are returned to the game area 3a (see FIG. 17) from the discharge ports 42 on both sides (particularly the right side) of the lower stage 440.

  The rate at which the falling balls B are received by the box-like protrusions 425 is highest when the box-like protrusions 425 are stopped at the center of the display window 20a. On the other hand, during rotation of the box-shaped protrusion 425, the ball travels in the left and right direction only by contacting the box-shaped protrusion 425, or passes through without contacting and falls to the lower stage 440 as it is. Since a large amount of B is generated, the acceptance ratio is reduced.

  10 to 12 (Embodiment 2), FIGS. 13 to 15 (Embodiment 3), and FIGS. 16 to 18 (Embodiment 4) have the same functions as those in FIGS. 2 to 4 (Embodiment 1). The parts having the same reference numerals are designated and the description thereof is omitted.

  In the above description, only the rotary drum type display device in which three drums are arranged has been described, but the present invention may be applied to a rotary drum type display device in which one, two, or four or more drums are arranged.

  When the rotary drum type display device is constituted by a plurality of drums, the drum on which the protrusions (sorting member; sorting mechanism) are installed can be arbitrarily selected. At that time, the drum to be stopped and displayed last may be changed from the middle drum 20C, and a protrusion may be provided on the changed drum.

  In the embodiment, the common axis O of each of the drums 20L, 20C, and 20R is installed in the left-right direction (for example, the horizontal direction), but may be installed in the up-down direction (for example, the vertical direction). In this case, the protrusions 25, 325, and 425 arranged on the outer peripheral surface of the drum move, for example, from the left to the right on the display window 20a in accordance with the rotation of the drum. Therefore, if the tip portion rotation locus K1 and the ball movement locus K2 are configured to overlap at least partially as in the above embodiment, the ball 25 depends on whether the protrusions 25, 325, 425 and the ball B are in contact with each other. It becomes possible to sort the traveling direction of B.

  When winning at the first start winning port 12 (electricity Chu) or the second start winning port 41 (starting port), it is desirable to perform the lottery independently and hold the lottery results separately. At that time, the following changes may be made to the second start winning opening 41.

(1) If the second start winning opening 41 is set to be more advantageous for the player than the first starting winning opening 12, the player is willing to play the game with the aim of winning the second start winning opening 41. Can be increased. As an advantageous setting for the player, for example,
-Winning probability of jackpot;
・ Winning ratio of promising jackpots among jackpots;
・ Number of rounds in jackpot, number of winning prizes in one round, number of winning balls per prize;
・ If there are multiple types of jackpots with different numbers of rounds, the winning percentage for jackpots with many rounds.

  (2) The second start winning opening 41 may be processed as a starting opening equivalent to the first starting winning opening 12. Although weighting the second start winning opening 41 as in (1) is more effective in increasing the interest of the player, this simplifies processing and reduces costs.

  (3) The second start winning opening 41 may be used as a winning opening for executing some processing. For example, when the second start winning opening 41 is won, the big winning device 13 is opened for a predetermined time, and when a ball that has entered the big winning opening passes through a special area in the big winning opening, a big win is generated. Can also be used.
