Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine equipped with a stage structure suitable for use in a structure for adjusting a winning probability at a stage start winning opening of a stage provided in a center accessory.

  Generally, as a game machine, for example, a pachinko machine, a game ball staying in a ball tray is launched into the game area of the game board according to the operation of the launch handle, and then led to obstacle nails or windmills in the game area. On the other hand, there are known ones configured to flow down the board surface and enter various winning holes, or flow into the outlets at the lower part of the game area without entering.

  With such a pachinko machine, when a player enters a general winning opening, a corresponding number of game balls are paid out, and when a player enters a starting chucker, a lottery or production pattern is drawn based on this. And a predetermined number of game balls are paid out. Depending on the production pattern selected based on this lottery result, for example, using a liquid crystal display screen provided in the center part of the game board, visual expression through various lighting devices, auditory expression through speakers, etc. Various productions are performed. When a win (hereinafter also referred to as a “big hit”) occurs (that is, when a lottery in a special game state is won), a big winning opening called an attacker is opened, and a large number of games corresponding to the pitch It becomes a special game state advantageous to the player to which the ball is paid out.

  In such a pachinko machine, a part of the game ball launched into the game area is introduced into the guide path provided in the center decoration, and the introduced game ball is discharged from the discharge port at the downstream end of the guide path to the stage. In this case, a configuration that is configured to roll is known (see Patent Document 1).

  In the pachinko machine described in Patent Document 1, the game ball introduced and released into the guide path has a reduced rolling speed while regularly reciprocating left and right on the first stage. If the center concave surface portion is successfully moved when falling from the circular space formed by the guide groove to the third stage below it, the central concave surface portion falls to the front lower starter chucker, It is configured to win with probability.

  The stage in the pachinko machine has the first stage formed in a drum bridge shape so as to follow the discharge port, and the second stage formed in a reverse drum bridge shape so as to follow the lower front side of the first stage, The third stage is located below the first stage and rolls the game ball dropped from the circular space. Below the first stage, there are provided a central concave surface portion that determines the course of the game ball dropped from the guide groove, and concave surface portions formed on the left and right sides of the central concave surface portion. The game ball guided to the central concave portion can win the starter chucker with high probability, and the game ball guided to the concave portion can win the starter chucker with low probability. In addition, on the left and right sides of the guide groove on the back wall, there are formed notches and a drop groove that allows the game ball that has not been guided to the guide groove to fall to the second stage without being guided to the central concave surface portion or the concave surface portion. The game ball that has fallen from the drop groove rolls along the slope, and in many cases, falls in a direction different from that of the starting chucker.

  By the way, in the pachinko machine described in Patent Document 1, the game balls launched into the game area and introduced into the introduction path are guided to the first stage, and the starter chucker wins a prize or wins according to different rolling situations. Although it can be distributed so that it can be dropped again into the game area without making it, the winning probability of introducing the game ball introduced to the introduction path from the introduction port and released to the stage to the starter chucker depends on the type of machine installed It cannot be adjusted easily.

  In recent years, pachinko machines that have been manufactured based on the same theme have increased in the number of cases in which multiple types with different jackpot lottery probabilities (probability of lottery for special game state transition) are manufactured and sold. Under such circumstances, for example, in the case of the pachinko machine of Patent Document 1, the probability that the game ball introduced into the taxiway will reach the central concave portion is easily changed for each model, A structure that can make a difference in the winning frequency is required, but the above-mentioned stage structure cannot meet such a demand. Therefore, even for the same type of pachinko machines with the same theme, it is necessary to change the mold and create a different stage structure, which increases the manufacturing cost and causes a cost increase. There was a risk of becoming.

  Next, the control system of the pachinko machine 1 in the present embodiment will be described with reference to FIG. The figure is a block diagram showing a control system of the pachinko machine.

  That is, the present control system includes a game control device 80, a start chucker opening / closing solenoid 70, an attacker opening / closing solenoid 71, a sound emitting device 12, and a lighting device for effects 8, 11, which are electrically connected to the game control device 80. And an image display device 35.

  The game control device 80 includes the main control board 40 and the sub control board 38 shown in FIG. The main control board 40 manages the entire operation of the pachinko machine 1 in an integrated manner, and includes a system program for managing the entire operation of the pachinko machine 1 and a semiconductor memory in which a game execution program is stored in advance. And a storage unit (not shown) and a microprocessor (MPU) (not shown) that executes these programs. The sub-control board 38 is mainly configured to perform display control of image display, effects such as sound effects, and effect light.

  The game control device 80 includes a winning determination unit 81, a winning signal output unit 82, a lottery unit 83, a normal symbol lottery unit 94, a game control unit 86, a holding unit 87, an operation control unit 88, an operation determination unit 89, and an operation determination unit 90. , Production control means 91 and display control means 92 are provided.

  The winning determination means 81 includes a starting chucker 27, general winning openings 25a, 25b, 26a, 26b, an attacker 5 and the like that are launched into the game area 3a by a launching device (not shown) operated by operating the launching handle 2. When any of the above is won, it is determined that there has been a win.

  The winning signal output means 82 outputs a winning signal indicating that winning has been made to the corresponding start chucker 27, general winning openings 25a, 25b, 26a, 26b, the attacker 5, etc., when winning determination is determined by the winning determination means 81.

  The lottery means 83 executes a jackpot lottery (that is, a lottery to determine whether or not to shift to the special game state) in response to a winning of a game ball launched into the game area 3a. In other words, the lottery means 83 is advantageous to the player until the next jackpot is won when the winning signal corresponding to the starting chucker 27 from the winning signal output means 82 is input, with the winning with less than the maximum number of reserved balls. A jackpot random number is acquired and a jackpot lottery is executed so as to win either one of the probability fluctuation that becomes a special state that can add value and the normal hit that does not become the special state.

  The lottery means 83 is a lottery based on the production random number value in the case of winning the winning hit in the jackpot lottery. As a result of the change, the symbol such as “111” corresponding to the winning change is displayed on the jackpot active line of the image display device 35. A variation pattern to be finally aligned is determined, and a variation pattern signal to that effect is output. The “big hit effective line” means a position (line) where symbols should be arranged in a row in order to obtain a big hit. In addition, the lottery means 83 determines a variation pattern in which a symbol such as “222” corresponding to the normal hit is finally aligned on the jackpot active line as a result of the change when the normal win is won by the big hit lottery, A fluctuation pattern signal is output. Further, when the lottery means 83 is out of the big hit lottery, as a result of the fluctuation, the lottery means 83 determines a fluctuation pattern that the symbols such as “252” corresponding to the loss are finally aligned on the big hit effective line, and the fluctuation pattern to that effect Output a signal.

  The normal symbol lottery means 94 performs the normal symbol lottery for opening and closing the start chuck 27 with the game ball passing to the normal symbol operation gate 32 as an opportunity.

  The game control means 86 sends to the effect control means 91 a command that triggers the sound emitting device 12, the effect lighting devices 8, 11 and the lighting device 42 to emit sound and emit light. In addition, the game control means 86 sends to the display control means 92 a signal relating to the contents of the effect related to the jackpot lottery to be displayed on the image display device 35 in accordance with the preset effect data and the lottery result of the lottery means 83. .

  The holding unit 87 receives the variation pattern signal output from the lottery unit 83 and sequentially stores the variation pattern as a holding ball that is a result of the lottery performed each time the winning is made to the starting chucker 27. The storage status is lit and displayed on a jackpot lottery hold display device (not shown) so that there are a maximum of four hold balls. The holding means 87 always determines whether or not the number of held balls is, for example, four. While the number of held balls is four, the lottery lottery is not performed regardless of winning the starting chucker 27. . Note that the number of reserved balls that are lit and displayed as the reserved balls is not limited to the “maximum of four”, but may be set as appropriate, for example, three or less, or five or more.

  The operation control means 88 sends a drive signal to the start chucker opening / closing solenoid 70 based on a signal indicating the start of operation of the operation determination means 90 to actuate the solenoid 70 to open or close the start chucker 27. Further, the operation control means 88 sends a drive signal to the attacker opening / closing solenoid 71 to actuate the solenoid 71, and when a big hit occurs due to the lottery in the lottery means 83, the attacker 5 is opened and a predetermined number of winnings are completed (or a predetermined time). Control is performed so that the closing operation is repeated a predetermined number of times (predetermined rounds) every time (a).

  The operation determination unit 89 determines whether or not a condition for operating the starter chuck opening / closing solenoid 70 and the attacker opening / closing solenoid 71 is satisfied. That is, in the starter chucker opening / closing solenoid 70, when the “satisfaction” of the opening / closing of the starter chucker 27 is satisfied, the normal symbol lottery means 94 wins in the normal symbol lottery performed separately from the big hit lottery of the lottery means 83. It is. In the attacker open / close solenoid 71, when the "conditions" for the opening of the attacker 5 are met, three big symbols from the state of so-called reach (including so-called super reach and normal reach) are aligned on the big hit effective line and the big hit This is a case where it occurs, and the time when “the condition is satisfied” of the blockage of the attacker 5 is the case where winning in all rounds when the jackpot occurs is completed.

  In response to the determination signal from the operation determination unit 89, the operation determination unit 90 determines the start of operation of the starter chuck opening / closing solenoid 70 and the attacker opening / closing solenoid 71, respectively.

  In response to a command from the game control means 86, the effect control means 91 drives the sound emitting device 12 to emit sound, and the effect lighting devices 8 and 11 emit light to produce an effect appealing to the player's hearing and vision. Do.

  The display control unit 92 drives the image display device 35 in accordance with the signal from the game control unit 86, and displays the effect such as the contents centering on the big win lottery result so as to appeal to the player's vision. At that time, the display control unit 92 displays each lottery result by the lottery unit 83 on the screen 35a of the image display device 35 in time series.

  Next, the effect | action by this pachinko machine 1 is demonstrated, referring also the flowchart of FIG.

  That is, when a player who is seated facing the pachinko machine 1 holds the launch handle 2 and rotates it to an appropriate angle (step S1), the game ball 3 is played at predetermined time intervals by the operation of the launch device. Fired continuously towards Then, a large number of game balls that are launched into the game area 3a and roll and fall are timely awarded to the starter chucker 27 and the general winning holes 25a, 25b, 26a, and 26b, or roll and fall without being involved in these. Then, the game area 3a is discharged to the back side of the game board 3 from the lowermost outlet (not shown).

  When a part of the game ball launched into the game area 3 a enters the warp introduction port 37, the game ball is discharged to the stage S through the discharge port 44. The released game ball rolls on the stage S, and the game ball that has successfully dropped into the drop guide hole (not shown) has a high winning probability (approximately 100%) to the starting chucker 27 via the discharge port 49. ).

  The game ball released from the discharge port 49 wins the starting chucker 27 with a high probability as described above, but may not win depending on the contact state with the obstacle nail 30. On the other hand, most of the game balls that are not introduced into the drop guide hole are released below the stage S and fall in a direction different from the starter chucker 27. The so-called jump nail (not shown) driven to the left and right of the obstacle nail 30 or the road nail (not shown) arranged in the left-right direction from the jump nail is rebounded, Some of them fall and win the starting chucker 27.

  By the way, when a game ball wins any of the starting chucker 27 and the general winning openings 25a, 25b, 26a, and 26b, the winning determining means 81 determines the winning and the winning signal output means 82 outputs a winning signal. Output (step S2).

  Then, when winning the lottery lottery (step S3), when the lottery means 83 turns on the winning flag, the lottery based on the production random number value determines the type of jackpot, that is, the variation pattern corresponding to the probability variation or the normal variation. .

  Thereby, in step S4, the winning symbol to be displayed on the image display device 35 is set, and the lottery means 83 outputs the fluctuation pattern signal to that effect and until the effect display based on the fluctuation pattern signal is completed. Turns on the symbol variation prohibition flag to prevent transmission of the next variation pattern signal, sets a symbol variation timer for measuring the time to release the turned on symbol variation prohibition flag, and transmits the variation pattern signal. In response to this, the number of reserved balls is decremented by one. On the other hand, if the lottery is lost in the lottery, a variation pattern is determined by the lottery based on the production random number value so that the symbols corresponding to the loss are finally obtained as a result of the variation. As a result, the off symbol displayed on the image display device 35 is set, and the lottery means 83 outputs a variation pattern signal to that effect, turns on the symbol variation prohibition flag, sets the symbol variation timer, and sets the variation pattern. The number of reserved balls is decremented by 1 in response to the signal transmission.

  Then, based on the fact that the game control means 86 transmits to the display control means 92 a signal relating to the contents of the effect to be displayed on the screen 35a of the image display device 35, the display control means 92 drives the image display device 35, The contents related to the jackpot lottery result are displayed so as to appeal to the player's vision (step S5). At this time, if a command is issued from the game control means 86, the effect control means 91 drives the sound emitting device 12 to emit sound or synchronizes the effect lighting devices 8 and 11 in accordance with the effect on the screen 35 a. The light emission is driven and the operation is controlled so as to increase the production.

  If the lottery result displayed on the screen 35a is a big hit decision, the operation control means 88 sends a drive signal to the attacker opening / closing solenoid 71 at a predetermined timing based on the signal indicating the operation start decision of the operation decision means 90. Then, the solenoid 71 is operated to open the attacker 5, and the operation of closing every time a predetermined number of winnings are completed (or a predetermined time elapses) is repeated a predetermined number of times (predetermined rounds). Thereby, a large amount of game balls corresponding to the game balls won in the attacker 5 are paid out from the ball supply port 17 to the dish unit 16 (step S6).

In the above-described embodiment, the movement trajectories L ₁ and L ₂ in the introduction adjusting unit Ad are changed by appropriately replacing the trajectory changing members 61 and 62 having different thicknesses at the stage S, for example, in the manufacturing / shipping stage. Thus, the introduction probability to the guide port 39 can be varied. That is, when the locus changing member 61 having a thickness about half the thickness of the locus changing member 62 is attached to the wall surface 34, as shown in FIG. 4, the game flows down from the rolling path 54 side and rolls in the direction of arrow A. balls Ba moves rolling gentle slope 57a along the rolling surface 61a, enters the introduction adjuster Ad through the movement locus L ₁ closer to the guide opening 39. Therefore, the game ball Ba passes through a wide portion of the second inclined surface 60 and also passes through a narrow portion of the first inclined surface 59, so that the game ball Ba receives a large amount of the inclination to the outside of the stage by the second inclined surface 60. As a result, as indicated by an arrow C in FIG. 4A, the frequency of rolling so as to drop from the introduction adjustment unit Ad downward to the stage is increased. This tendency is the same in the case of the game ball Ba introduced from the right warp introduction port 37 and released to the stage S. As shown by the arrow c in FIG. The frequency of rolling so that it falls to the top is increased.

On the other hand, when the locus changing member 62 having a thickness about twice the thickness of the locus changing member 61 is attached to the wall surface 34, the locus changing member 62 flows down from the rolling path 54 side and rolls in the direction of arrow A as shown in FIG. game ball Ba is rolling moves the gentle slope 57a along the rolling surface 62a, enters the introduction adjuster Ad through the movement track L ₂ farther from the guide opening 39. Therefore, the game ball Ba passes through a narrow portion of the second inclined surface 60 and also passes through a wide portion of the first inclined surface 59, so that the game ball Ba receives many actions of inclining the inside of the stage by the first inclined surface 59. As a result, as indicated by an arrow B in FIG. 5A, the frequency of rolling from the introduction adjusting unit Ad toward the guide port 39 increases. This tendency is the same in the case of the game ball Ba introduced from the right warp introduction port 37 and released to the stage S. As shown by the arrow b in FIG. The frequency of rolling toward 39 is increased.

  As described above, according to the stage structure in the present embodiment, a difference in the winning frequency to the starter chucker 27 is brought about, and a winning situation according to the probability of the lottery to shift to the special game of the corresponding model can be easily created. For this reason, it becomes possible to reduce the expense for newly manufacturing a different metal mold | die, and to reduce the manufacturing cost of the pachinko machine 1.

  Further, according to the present embodiment, rolling in the direction of the guide port 39 acting on the game ball Ba passing through the first and second inclined surfaces 59 and 60 according to the movement locus changed by the locus changing members 61 and 62. The power can be adjusted. For this reason, the introduction probability to the guide port 39, that is, the introduction probability to the starter chucker 27 can be easily adjusted by a simple configuration formed on the stage S by combining the first inclined surface 59 and the second inclined surface 60. Can do. A rolling path 54 is provided between the warp introduction port 37 and the rolling path 57 to directly receive and roll the game ball Ba introduced from the warp introduction port 37, and the rolling path 54 is It has a guide groove 55 that extends along the rolling path 57 one step above the rolling path 57 and can guide the rolling game ball Ba to the guide port 39. For this reason, it is possible to select the winning in the rolling path 54 before selecting the presence or absence of winning in the starting chucker 27 in the rolling path 57, and accordingly, the player's attention to one game ball Can be maintained for a relatively long time.
