Description

  The present invention relates to a pachinko gaming machine that plays a symbol combination game on display means provided on a game board.

  Conventionally, as a pachinko gaming machine, a gaming machine that displays a plurality of types of symbols on a game board and performs a symbol combination game is known. This type of pachinko machine is provided with a symbol display device for variably displaying symbols, and a start winning device that triggers a symbol combination game when a game ball launched on the game board surface wins. ing.

  As a symbol display device of a pachinko gaming machine, for example, a liquid crystal screen or the like that can display symbols such as a numerical symbol, a character symbol, and a symbol symbol in three rows is used. For example, a case where three rows of symbols change as a display of variations in symbols in a pachinko gaming machine will be described. First, symbols in each row start to display variations, and after a predetermined time variation display, for example, when viewed from the player side, The display is stopped in the order of left symbol → right symbol → middle symbol, and a predetermined display pattern is displayed.

  When a game ball wins the starting winning device of the game board of the pachinko gaming machine, three rows of symbols on the display device start variable display. After a predetermined fluctuation time has passed in the display device, the symbols in each column are fixedly stopped at specific symbols, and a plurality of predetermined symbols are displayed on the display device, and a symbol combination game is played. A process in which the display of the symbol starts to fluctuate in the display device and fluctuates for a predetermined time and then stops is called fluctuating display. The time from the start of the change display to the stop is referred to as the time related to the change display, or simply the change time.

  In the display device of the conventional pachinko gaming machine, the variable display is prepared based on a plurality of variable display patterns (variation patterns) having different variation times, and a specific variation pattern is selected from the patterns. To change the display. In the conventional pachinko gaming machine, in the case of a normal gaming state excluding the time of probability fluctuation, the fluctuation time in the case of so-called off, excluding the time of reach appearance and the time of big hit, is a substantially constant time.

  In recent years, pachinko gaming machines in which the time required for variable display changes have emerged in the case of detachment (see, for example, Patent Document 1). This is to shorten the fluctuation time when the number of reserved balls is three or four with respect to the fluctuation time when the number of held balls is one or two. By selecting a variation pattern with a shorter variation time than the variation pattern set at the above-mentioned substantially constant variation time when the number of retained balls is large as described above, the variation time in the event of a loss is shortened. The digestion of the ball can be accelerated and the number of symbol combination games within a predetermined time can be increased.

Special opening and closing No. 4-135586 (page 3)

  However, the conventional pachinko gaming machine that shortens the variation time when the number of balls on hold is large, even if it is formed so that the variation time is shortened by reaching the predetermined number of balls on hold, If it is easy to win a game ball in the start winning device by adjusting the nail of the machine, etc., even though the change time is shortened and the digestion of the hold ball is accelerated, more wins will be held and it will be held There was a problem that the situation with many balls could not be solved and the symbol combination game could not be digested smoothly.

  Contrary to the above state, when the game ball is difficult to win the start winning device due to nail adjustment or the like, there are few cases where the number of reserved balls increases to a predetermined number or more. However, it is still possible that a large number of game balls win the start winning device accidentally at a time and the number of held balls becomes a predetermined number or more. Also in this case, in the pachinko gaming machine that shortens the variation time when the number of held balls is large, the variation time is shortened and the symbol combination game is quickly digested.

  However, in the case of a gaming machine in which it is difficult for the game ball to win the start winning device, the time when the symbol combination game is not performed becomes long, except when a large number of game balls are won accidentally. There has been a problem that the state of being scraped will continue for a long time.

  In order to solve the above problems, a pachinko gaming machine has been proposed which has a “variation shortening button” and has a function that allows the player to arbitrarily shorten the variation time by pressing the button. However, in this case, there is a problem that a fair game cannot be provided due to a difference in the number of prize balls obtained between skilled players and general players who are not so skilled in games, and a variation shortening button is not provided. There is a problem that the operation is troublesome for the player and the player cannot concentrate on the game.

  In addition, there is a game machine that has no upper limit on the number of reserved balls so that an invalid winning ball does not come out in a game ball won in the start winning device, but even in that case, if the winning rate is high, always It will be in the state where there are many reservation balls. As a result, the symbol combination game cannot be digested smoothly, and the player is uncomfortable.

  The present invention has been made to solve the above-described drawbacks of the prior art, and an object thereof is to provide a pachinko gaming machine that does not cause discomfort to the player by optimizing the variation time of the symbol combination game. It is what.

Is a summary.

  The pachinko gaming machine according to the present invention is a pachinko gaming machine that starts a shortened variation that shortens the variation time of the symbol combination game on condition that the number of retained balls stored by the retained ball storage means is equal to or greater than a predetermined value. Since the variation time of the combination game is optimized according to the winning situation of the start winning device, there is an effect that the player does not feel uncomfortable.

In the case of a conventional pachinko gaming machine that shortens the fluctuation time of the unusual symbol variation when the number of reserved balls stored by the reserved ball storage means is a specific number or more, the number of reserved balls stored by the reserved ball storage means is It is irrelevant to the winning rate, and it cannot be said that the fluctuation time of the symbol combination game accurately reflects the winning situation of the game ball to the starting winning device.
That is, if it is easy to win game balls in the start winning device by adjusting the nails of the pachinko gaming machine, the state where there are a large number of reserved balls cannot be resolved, and the symbol combination game may not be digested smoothly. On the other hand, in the case of a pachinko gaming machine where it is difficult for a game ball to win the start winning device, if the game ball happens to win together in the start winning device, the actual gaming state may be difficult to win the start winning device. Regardless, the variation time becomes short, and the state where the symbol variation is not performed continues for a long time.
On the other hand, in the present invention, it is possible to accurately grasp the winning situation with respect to the start winning device and to appropriately set the symbol variation time according to the situation. There is an effect that there is no fear of scraping.

  In addition, when the winning variation rate reserve ball number changing means has a high winning rate, it selects a smaller value as a predetermined value of the reserved ball number as a condition for starting the shortening variation than when the winning rate is low. When the rate is low, compared to when the winning rate is high, when a large value is selected as the predetermined value for the number of reserved balls, which is the condition for starting shortening fluctuations, when the winning rate is high, the number of reserved balls is small In some cases, the variation time is shortened by starting a shortened variation, while when the winning rate is low, the variation time is lengthened so that the shortened variation is not started even when the number of reserved balls is large. The game can be digested smoothly, and the player's interest can be attracted by reducing the number of patterns not changing as much as possible.

  Further, when the present invention includes a winning rate measuring means, the winning rate measuring means stores a firing number counting means for counting the number of game balls launched on the game board surface, and stores the number of game balls counted by the firing number counting means. Firing number storage means, winning number counting means for counting the number of game balls won in the start winning means, winning number storage means for storing the number of game balls counted by the winning number counting means, and the number of winning prizes stored When the winning rate calculation processing means for calculating the winning rate based on the memorized number of shots is used, the winning of the game ball to the starting winning means is more accurately performed using the number of shots and the winning number for the starting winning means. Since the situation can be measured, it is possible to select a variation time according to the entity such as a difference in the winning rate by adjusting the nail of the gaming machine.

  Hereinafter, the present invention will be described in detail using one embodiment of the pachinko gaming machine of the present invention. As shown in FIG. 1, in the pachinko gaming machine 1, a vertical rectangular middle frame 12 for setting various gaming components is assembled in an openable and closable manner on the front side of the opening of the outer frame 11 of the machine body. On the front side of the middle frame 12, the front frame 14 provided with a glass frame for protecting the game board 13 arranged inside the machine and the upper ball tray 15 are assembled and aligned so that both can be opened and closed in a laterally open state. Has been. Further, a lower ball tray 16, a hitting ball launching device 17, and the like are attached to the lower part of the middle frame 12.

  Near the center of the game area 19 of the game board 13, a display device 18 is provided as a display means for performing a symbol combination game in which a plurality of types of symbols are variably displayed and fixedly stopped after a predetermined variation time. The display device 18 is provided with a display unit H including a liquid crystal display (LCD) or the like, and symbols of the symbol combination game are displayed on the display unit H. As the display device 18, a liquid crystal display (LCD), a cathode ray tube (CRT), a synthetic resin or the like is formed into a cylindrical shape and can be rotated, and a rotating drum type having a plurality of designs on its surface, a light emitting diode (LED), etc. It is possible to use a dot display type in which a plurality of luminous bodies are arranged and various symbols are represented by the emitted light, and other devices. These display devices 18 are provided with a display portion H on which symbols are displayed.

  An effect image or the like for producing a symbol combination game can be displayed on the display unit H. As symbols used in the symbol combination game, various symbols such as character symbols, pictures, character symbols and the like that can be identified by the player can be used.

  As a plurality of types of symbols used in the symbol combination game of the display unit H, for example, the first symbol A, the second symbol B, and the third symbol C are configured by a plurality of types of numeric symbols. More specifically, the first symbol A, the second symbol B, and the third symbol C are “0”, “1”, “2”, “3”, “4”, “5”, “6”, respectively. , “7”, “8”, and “9” are configured to be variably displayed as a symbol string. Then, for each symbol row of the first symbol A, the second symbol B, and the third symbol C, any numerical symbol in the symbol row is definitely stopped and displayed on the display unit H.

  The combination of the 1st symbol A, the 2nd symbol B, and the 3rd symbol C that are displayed after being definitely stopped is one of “big hit”, “out of reach”, and “usually out of”. In this embodiment, the shortened variation is started on the condition that the number of reserved balls is equal to or greater than a predetermined value in the case of a symbol combination game in which “usually off” is displayed.

  “Big hit” is the same as the first symbol A, the second symbol B, and the third symbol C displayed on the display unit H. When “big hit” is displayed on the display unit H of the display device 18, the special prize-winning device 23 is opened, and the player is given a chance to acquire a large number of game balls.

  In addition, “out of reach” is when two specific columns (for example, first symbol A and third symbol C) stop at the same symbol, and the remaining one column (for example, second symbol B) continues to fluctuate. In this case, the game stops at a symbol different from the symbols of the two specific rows and does not win.

  If all the different symbols are displayed as the first symbol A, the second symbol B, and the third symbol C in a definite way, they do not fall under either “big hit” or “out of reach”. Out of place ".

  In the case of “unusual”, 10 types of numerical symbols “0” to “9” are displayed on the display unit H as “0” → “1” → “2” → “3” → “4” → “5”. In the order of “6” → “7” → “8” → “9” → “0”, the variable display (scroll display) is started so that the numerical symbols are in ascending order. After the symbols are displayed in a variable manner for a predetermined time, any one of the 10 types of symbols that are variably displayed for each column is the first symbol A, the second symbol B, and the third symbol. Each of the symbols C in the symbol C is displayed in a definitely stopped state.

  A guide rail 20 is provided on the surface of the game board 13 so as to be connected to the ball hitting device 17 and surround the game area 19. Further, at the entrance of the game area 19 of the guide rail 20, a passage detection switch 21 for counting the game balls launched from the hit ball launching device 17 into the game area 19 is attached. Examples of the passage detection switch 21 include a proximity switch that provides a passage for a game ball and magnetically detects the passage of the game ball to the passage.

  Near the center of the game area 19 of the game board 13, a start winning device 22 is provided below the display device 18 so as to be opened and closed by a solenoid (not shown). Further, below the start winning device 22, there is provided a special winning device 23 that can be opened and closed by a solenoid (not shown). Further, below the special prize-winning device 23, there is provided an out port 24 through which game balls flow to the back surface. The start winning device 22 and the special winning device 23 are provided with a winning detection switch (not shown) for detecting whether a game ball has won or passed.

  The winning of the game ball to the start winning device 22 as the start winning means is an opportunity to start the symbol combination game on the display unit H of the game board 13. Then, after the symbol variation starts on the display unit H, the symbol combination game is performed by a fixed stop after a predetermined variation time. When a game ball is won in the start winning device 22 while the symbols are changed on the display unit H, the winning of the game ball is stored in the holding ball storage means 8 as a holding ball. Generally, there is an upper limit to the number of reserved balls (the number of reserved balls P) stored in the reserved ball storage means. In the pachinko gaming machine shown in FIG. 1, the maximum number of reserved balls P is set to 4.

  When the number of held balls is 0 (zero), the symbol combination game is variably displayed on the display unit H by winning a game ball to the start winning device 22, and when the number of held balls is other than 0 (zero), The symbol combination game is variably displayed based on the stored value of the number of reserved balls. The value of the number of held balls is incremented (+) 1 by winning a game ball to the start winning device 22 and subtracted (-1) by starting the symbol combination game.

  As shown in the block diagram of FIG. 2, the pachinko gaming machine of the present invention measures the winning rate Q (the ratio of the number of game balls won in the starting winning means to the number of game balls launched on the game board surface). In order to change the predetermined value R of the number of reserved balls, which is a condition for starting a shortening variation that shortens the variation time of the symbol combination game, according to the winning means Q measured by the measuring means 2 and the winning rate measuring means 2 The shortening variation condition reserved ball number changing means 9 is provided. The predetermined value R of the number of reserved balls, which is a condition for starting the shortening variation, is changed according to the winning rate Q by the shortening variation condition retaining ball number changing means 9. In the symbol combination game, the variation pattern setting unit 10 sets a shortened variation in which the variation time is shortened on the condition that the number of retained balls P stored by the retained ball storage unit 8 is equal to or greater than a predetermined value R. The display unit (display device) 18 starts the variable display.

  A specific example of the shortened variation condition reserved ball number changing means 9 for changing the predetermined value R of the reserved ball number according to the winning rate Q will be described with reference to FIG. FIG. 3 is an example of a shortened variation condition reserved ball number table in which the winning rate Q and the predetermined value R of the reserved ball number are associated with each other. In the table of FIG. 3, when the winning rate Q is 33 or more, the predetermined value R of the reserved ball number is 2, and when the winning rate Q is less than 33 to 25 or more, the predetermined value R of the held ball number is 3, and the winning number is When the rate Q was less than 25, the predetermined value R of the number of reserved balls was set to 4. That is, the setting of the shortened variation condition reserved ball number changing means shown in the shortened variation condition reserved ball number table of FIG. 2 is compared with the case where the winning rate Q is high [33 or more] and the winning rate Q is low (less than 25). Thus, a value [2] smaller than the predetermined value [4] when the winning rate Q is low is selected as the predetermined value R of the number of reserved balls as a condition for starting the shortening variation, and the winning rate Q is low. In the case [less than 25], the predetermined value R when the winning rate Q is high [2] as the predetermined value R of the number of reserved balls, which is a condition for starting the shortening variation, compared with the case where the winning rate Q is high [33 or more] A larger value [4] is selected.

  The shortened variable condition reserved ball number changing means 9 uses the shortened variable condition reserved ball number table in which the winning rate Q and the predetermined value R of the reserved ball number correspond to each other as shown in FIG. A predetermined value R of the number of balls is determined, and the data is sent to the fluctuation pattern setting means 10 as shown in FIG. On the other hand, the reserved ball storage means 8 sends data of the number of reserved balls P to the variation pattern setting means 10. The variation pattern setting means 10 compares the predetermined value R of the number of reserved balls with the number of reserved balls P, and determines whether or not the variation pattern displayed on the display means 18 is a shortened variation. The display means 18 displays a symbol combination game having a predetermined variation time based on the variation pattern selected as a result of the determination.

  In the present invention, the “variation pattern” means the time from the start of the change of the symbols (first symbol A, second symbol B, and third symbol C) on the display unit H until the fixed stop at a predetermined symbol ( Variation time) and the operation patterns of the first symbol A to the third symbol C within the variation time.

  As shown in FIG. 4, the winning rate Q is measured by the winning rate measuring means 2. The winning rate measuring means 2 includes a firing number counting means 3 that counts the number of game balls that have been fired in the game area 19 (hereinafter referred to as a firing number X), a firing number storage means 4 that stores the firing number X, and a start winning device. The winning number counting means 5 for counting the number of game balls won in 22 (hereinafter referred to as the winning number W), the winning number storage means 6 for storing the winning number W, and the memorized winning number X and the memorized prize. The winning rate calculation processing means 7 calculates the winning rate based on the number W.

  The winning rate calculation processing means 7 calculates a winning rate Q based on the number of shots X stored in the number of shots storing means 4 and the number of winnings W stored in the number of winning prizes storing means 6. Specifically, To prepare a correspondence table in which the value of the number of shots X stored by the number of shots storing means 4 and the value of the number of winnings W stored by the winning number storage means 6 are associated, and setting the winning rate Q from this correspondence table Can do.

  The winning rate Q used in the shortened variation holding ball number changing means 9 is the number of fired X and the number of winning Y counted by the number-of-launch counting means 3 and the number-of-winning-counting means 6 when a game ball wins the starting prize-winning device 22. At that time, the winning rate Q is determined and a predetermined value R of the number of reserved balls is set. Further, whether or not to start the shortening variation is set based on the number of reserved balls P when the game ball wins the start winning device 22 and the predetermined value R.

  In the present invention, the “winning rate Q” means the ratio of the number of game balls won in the start winning means to the number of game balls (total number) actually fired on the game board surface, that is, the game area 19, and a certain number of shot game balls It is represented by the number of winning prizes (number) to the start winning means in the number. In this embodiment, the fixed number of game balls to be fired is 500. That is, the time when a game ball wins the start winning device 22 is “present”, and the number of game balls that have won the start winning device 22 while the number of game balls launched from “present” goes back to 500 “past”. Was the winning rate.

  In the pachinko gaming machine 1, the winning rate can be adjusted by the position of the nail arranged on the gaming area 19, the bending angle, the interval between the nails, and the like. The adjustment of the nail is performed by a skilled expert, but it is an extremely delicate operation that requires adjustment in units of 0.01 mm. Also, the winning rate varies depending not only on the adjustment of the nail but also on the adjustment of the handle of the player's hitting ball launcher 17 and the like.

  Hereinafter, a specific control circuit of the pachinko gaming machine of FIG. 1 will be described. As shown in FIG. 1, a main control board 30 is provided on the back side of the pachinko gaming machine 1 to control the game contents in an integrated manner. The main control board 30 is connected to a display control board 40 that performs display control on the display unit H of the display device 18.

  The main control board 30 is connected to a start winning device 22 and a special winning device 23 provided on the surface of the pachinko gaming machine 1, and controls a solenoid that drives an opening / closing door, a wing piece, etc. provided in the winning device. It is possible. The main control board 30 is adapted to receive detection signals from a winning detection switch and a passing detection switch for game balls provided on the winning devices 22, 23, the guide rail 20, and the like.

  The display control board 40 receives various control signals output from the main control board 30 and executes display control of the display unit H based on various control commands constituting the control signals. In the display unit H, a symbol combination game according to the control command is performed, and after the symbols are variably displayed for each symbol row, the symbols are steadily stopped and displayed as the first symbol A to the third symbol C.

  The main control board 30 is electrically connected to a lamp control board and a sound control board (not shown) as boards other than the display control board 40, respectively. The lamp control board inputs various control signals output from the main control board 30 and controls blinking of lamps provided on the front side of the gaming machine based on various control commands constituting the control signal. ing. Similarly, the audio control board receives various control signals output from the main control board 30 and controls the audio output device based on various control commands constituting the control signals.

  FIG. 5 is a block diagram showing an electrical configuration of a control board of the pachinko gaming machine 1 shown in FIG. As shown in FIG. 5, the main control board 30 includes a main CPU 31 for controlling the entire pachinko gaming machine 1, and a ROM 32 and a RAM 33 are connected to the main CPU 31. A ROM 32 connected to the main CPU 31 stores and holds a game control program for controlling the pachinko gaming machine 1. In the ROM 32, a jackpot determining random number (0-630), a jackpot symbol random number (0-9), a left symbol random number (0-9), a right symbol symbol random (0-9), a middle symbol random number (0) To 9), various random numbers such as reach determination random numbers (0 to 59), and various control commands corresponding to these various random numbers are stored and held.

  The jackpot determination random number (0 to 630) is extracted when a game ball wins the start winning device 22. That is, when the main CPU 31 receives a signal from the winning detection switch of the start winning device 22, a random number is extracted from the RAM 33, and it is determined whether or not a big hit is made based on the extracted random number value. The ROM 32 stores predetermined numerical values for determining a big hit (numbers for determining a big hit, for example, 7 and 373), and the main CPU 31 determines that a big hit is obtained when the extracted random number value matches the big hit value. judge. If there are 631 random numbers for determining the big hit, 0 to 630, and two big hit values, 7 and 373, the big hit probability of the pachinko gaming machine 1 is 631/2 = 315.1.

  The jackpot symbol random number is a random number for determining a symbol to be finally stopped when a jackpot value is extracted from the jackpot determination random number. The 10 numbers from 0 to 9 of the jackpot symbol random number are 10 types of symbols (“0”, “1”, “2”, “3”, “4”, “5”) provided in each symbol group. , “6”, “7”, “8”, “9”). When the jackpot is determined by extracting the jackpot determination random number, the number symbol corresponding to the numerical value extracted from the jackpot symbol random number is determined as a symbol to be fixed and stopped.

  Each outlier design random number is a random number for determining a design to be finally stopped when a numerical value other than the jackpot value is extracted from the jackpot determination random number. The left-shift symbol random number corresponds to the first symbol A, the middle-shift symbol random number corresponds to the second symbol B, and the right-shift symbol random number corresponds to the third symbol C. Further, 10 numerical values of 0 (zero) to 9 which are the numerical values of each of the off-set design random numbers are the 10 types of numerical symbols (“0”, “1”, “ 2 ”,“ 3 ”,“ 4 ”,“ 5 ”,“ 6 ”,“ 7 ”,“ 8 ”,“ 9 ”).

  The reach determination random number is extracted when a numerical value other than the big hit value is extracted from the big hit determination random number, and whether or not the display unit H performs an outlier reach effect (reach effect) with the extracted value. It is a random number to determine. For example, the above-mentioned reach effect stops the first symbol A and the third symbol C at the same symbol, and finally displays a symbol different from the symbols of the first symbol A and the third symbol C on the second symbol B. The symbol combination game is stopped after the final stop.

  A ROM 32 connected to the main CPU 31 stores predetermined reach determination values (for example, 3, 7, 13, 19, 29 for determining reach effect among random numbers for reach determination (for example, 60 from 0 to 59). ) Is stored. The main CPU 31 determines the reach effect when the extracted reach determination random number value matches the reach determination value. And reach production.

  In addition, a plurality of distribution random numbers are stored in advance in the ROM 32, and it is determined which one of the jackpot effect, the probability variation effect, the reach effect, etc. is used for effect display of the first symbol A to the third symbol C. It is a random number for. The effect patterns are divided into tables for each of a plurality of states, such as for big hits, out of reach reach, and usually for out of play, and the numerical values of the effect pattern distribution random numbers are assigned to each table. For example, when the big hit is determined by extracting the big hit determination random number, the main CPU 31 selects an effect pattern corresponding to the extracted value of the random number for the effect pattern distribution random number from the big hit effect pattern table. In the present invention, the “effect pattern” refers to an action pattern that is divided into patterns such as a jackpot action pattern, a reach action pattern, a normal deviation action pattern, etc., and each effect pattern is further subdivided. It becomes a fluctuation pattern. Therefore, the variation pattern includes a variation pattern that becomes a big win effect pattern, a variation pattern that becomes a reach effect pattern, a variation pattern that usually becomes a shift effect pattern, and the like.

Yes. The RAM 33 of the main control board 30 receives detection signals from the winning detection switch of the start winning device 22 and the passage detection switch 21 provided on the guide rail 20, and stores the number of shots X, the winning number W, and the like. The

  The RAM 33 stores and holds data on the number of reserved balls P among the game balls won in the start winning device 22 and control commands calculated by the main CPU 31. When the main CPU 31 instructs the display control board 40 to perform display control using a control command, the control command is displayed as a control signal (8-bit signals MD0 to MD7) via the output port 34 and the output buffer 35. It outputs to the board | substrate 40. FIG.

  The main control board 30 indicates, as control commands, a change start command indicating the change start of the first symbol A to the third symbol C and the change start command, and the first symbol A to the third symbol C for each column.

An effect pattern and specific control contents corresponding to a command indicating the effect pattern are stored and held.

  The display control board 40 reads the control signal and controls the display unit H. As a result, when the game ball wins the start winning device 22 or there is a stored value of the number of reserved balls, various internal processes are performed based on the obtained various random numbers and the like, and an operation pattern is displayed on the display unit H. The selected combination pattern is displayed on the display unit H as one of the big hit, out of reach reach, or out of reach, and the symbol combination game is played.

A passage detection switch 21 (provided on the guide rail 20) that detects the passage of the ball into the game area 19 and a signal that receives the signal from the passage detection switch 21 and counts the number of shots X It consists of CPU31.

  The number-of-fired storage means 4 is means for storing the number of game balls (number of shots X) fired from the hitting ball launching device 17 to the game area 19 counted by the number-of-fired counting means 3. As shown in FIG. 3, a RAM 33 connected to the main CPU 31 is used, and the number of shots X is stored and held in the RAM 33.

  In the pachinko gaming machine 1 shown in FIG. 1, processing when a game ball is actually launched will be described. When the game ball is launched by operating the hitting ball launching device 17, the game ball rises along the guide rail 20, is introduced into the game area 19 of the game board 13, and falls in the game area 19 from above to below. While the game ball falls on the game area 19, the game ball is guided to the upper part of the start winning device 22, the special winning device 23, and the like by a number of nails (not shown) provided on the game region 19. . Normally (in a case other than the big hit state), a part of the game balls launched into the game area 19 wins the start winning device 22, and the remaining many game balls are discharged from the out port 24 to the back side of the machine.

  When the launched game ball passes through the passage detection switch 21 and enters the game area 19, a detection signal is transmitted from the passage detection switch 21 to the main control board 30, and a shot number count signal is sent to the RAM 33 as a shot number storage means. Is sent. The firing number count signal is sequentially counted up by the action of the main CPU 31, and the number of game balls that have been fired is stored and held in the RAM 33 as the cumulative number X of fired balls.

  When a game ball in the game area 19 of the game board 13 falls on the game board surface and wins the start winning device 22, a winning detection switch provided in the start winning device 22 receives a game ball win. , And a winning number count signal is transmitted to the control board 30. The winning count signal is sequentially counted up by the action of the main CPU 31, and the number of winning game balls is stored and held in the RAM 33 as the accumulated winning number W. When the start winning device 22 wins, the winning number W and the firing number X at the time of winning are stored in the RAM 33 in association with each other.

  When a game ball launched from the hitting ball launcher 17 travels along the guide rail 20 toward the game area 19, it may return to the launcher without reaching the game area 19. Although this is called a return ball, in this embodiment, this return ball is not counted as the number of shots X. For this purpose, a passage detection switch 21 for confirming the number X of game balls fired provided on the guide rail 20 is attached to the tip of the guide rail 20 so as to count only the game balls that have reached the game area 19. The return ball that does not reach the game area 19 is formed so as not to be counted as the number X of game balls fired.

  When a game ball wins the start winning device 22, the main CPU 31 extracts a jackpot determining random number. Then, it is determined whether or not the big hit state is reached based on the extracted value. When a numerical value other than the big hit value is extracted from the big hit determination random number, the off symbol random number finally determines the symbol to be finally stopped on the display unit H. Further, when a numerical value other than the big hit value is extracted from the big hit determination random number, the reach determination random number is extracted, and the predetermined reach determination value in the ROM 32 of the main control board 30 and the value extracted by the main CPU 31 match. The reach state is determined, and the display unit H produces a shift reach.

  When a big hit or loss reach is extracted in random numbers for various judgments, the symbol change produced according to the predetermined effect pattern is performed after the start of the symbol change, the decision is stopped, and the big hit or loss is detected. Reach is displayed.

  When a deviation is normally extracted from the various random numbers for determination, a display of a normally deviation is displayed on the display unit H. In general pachinko machines, usually the most deviations appear. The variation time from the start of symbol variation to the final stop in the case of a normal deviation is determined by the variation pattern. In order to set a predetermined fluctuation pattern from among a plurality of fluctuation patterns, a fluctuation pattern setting process is performed. Hereinafter, control until the variation pattern is set will be described with reference to FIG.

  As shown in FIG. 6, after starting the process, it is first determined whether or not the probability is currently changing (S1). If the probability is not changing, the process proceeds to the determination (S2) of whether or not N game balls are fired. If the probability is changing, the process proceeds to the Y change start determination process (S7). Note that the pachinko gaming machine of the embodiment of FIG. 1 has a variation pattern in which the variation time of the symbol combination game is shortened during probability variation. In this embodiment, since the shortening variation according to the predetermined value of the number of reserved balls is not performed during the probability variation, the processing relating to the winning rate is unnecessary, so the processing of S2 to S6 is skipped.

  Next, in S2, it is determined whether or not a game ball has been fired. When there is a fire (Y), the fired number is incremented by 1 (S3). On the other hand, if there is no game ball fired (N), the process proceeds to a change start determination process (S7). Whether or not the game ball is fired can be determined by the presence or absence of passage of the passage detection switch 21 provided on the guide rail 20 on the game board surface.

  The number of fired X when the pachinko gaming machine is turned on is actually “0” (zero) because the game ball has not been fired, but “0” in consideration of virtual data described later. A specific value other than. In this embodiment, this is set to “500”, and processing is performed assuming that there are 500 shots when the power is turned on.

  If the number X of shots is incremented by 1 in S3, it is next determined whether or not a game ball has been won in the start winning device 22 (S4). This determination can be made by a winning detection switch provided in the start winning device 22. When there is a winning game ball (Y), the winning number is incremented by 1 (S5). On the other hand, if there is no winning game ball (N), the process proceeds to the change start determination process (S7).

  It should be noted that the winning number X at the time of power-on of the pachinko gaming machine is naturally “0” (zero), although it is natural that no gaming ball is fired at all. However, in consideration of virtual data described later, a specific value other than “0” is set. In the present embodiment, this is set to “30”, and processing is performed assuming that there are 30 winning numbers (among 500 firing numbers) when the power is turned on.

  The number of winnings accumulated by adding 1 to the number of winning game balls is stored in “winning number address”. Considering the virtual data at the time of power-on, the “winning number address” at the time of power-on is set to “003D”, and thereafter changes as needed by the process of S19 (described later).

  Next, a winning number firing number storage process (S6) is performed, and the process proceeds to a variation start determination process (S7). In the winning number firing number storage process of S6, for the past number of game ball fired X, the state of the winning (for example, information on how much the number of shots has been won in the start winning device 22) is stored. Process. Specifically, the processing of S10 to S20 shown in FIG. 7 is performed (described later).

  In the variation start determination process of S7 shown in FIG. 6, it is determined whether or not the variation of symbols A to C is started on the display unit H. When there is a game ball winning in the start winning device 22 or when there is a stored value of the number of held balls, the change of the symbols A to C starts, and the symbol combination game is performed on the display unit H.

  In the variation start determination process (S7) of FIG. 6, when the symbol variation is started, the process proceeds to a Y winning rate calculation process (S8). If the symbol is not changed (not started), the process proceeds to N return processing. The winning rate calculation process of S8 is a process of calculating the winning rate from the storage data (stored in the winning number firing number storage process of S6) that stores the state of winnings for the past 500 game ball shots. is there. A specific winning rate calculation process (S8) is performed by the processes of S21 to S22 shown in FIG.

  In the winning rate calculation process (S8), as shown in FIG. 8, first, the initial firing number storage address at the time of winning is incremented by 1, and the content of this address is used as a subtraction value used in the next process S22 (S21). Next, a numerical value obtained by adding 1 to the value obtained by subtracting the subtracted value from the number of winnings counted in S5 of FIG. Using this “winning rate”, a variation pattern is set in the variation pattern setting process of the next S9.

  In the winning rate calculation process, the winning rate can be calculated from a correspondence table in which the number of shots X and the winning number W are associated with each other. The number of fires in this case means the number of fired X when winning. As an example of a correspondence table between the number X of winning prizes and the number of winning prizes, an actual data table is shown in FIG. Each time a game ball launched into the game area 19 wins the start winning device 22, the number of winning is counted and the cumulative number of winning game balls is counted. This value is stored as “winning number W” in the winning number storage means 6 of the RAM 33 provided on the main control board 30. At the same time, the starting number X is stored in the start winning device 22 when the game ball is won. The value of the number of shots X is stored in the RAM 33 provided on the main control board 30 as “number of shots X when winning”. The real data table shown in FIG. 9 is obtained by associating the value of the “number of winning shots X” stored in the RAM 33 and the value of the “number of winning W” stored in the winning number storage means 6 with a correspondence table. .

  In the real-fire data table of FIG. 9, the winning number W and the winning-time number X are displayed when the number X is 500 to 1300. For example, in the top column of the table, the winning number W corresponds to the number of fires X at the time of winning so that the number X of winnings when the number of winnings W is “31” is “515”. ing. The next winning number W is “32”, which is the time when 17 shots are counted from “515” at the time of the 31st winning. Therefore, the number X of winning shots is “532”. In this way, hereinafter, the number of winning shots X corresponding to the number of winning prizes W is recorded until the number X of winning prizes when the winning number W is “82” is up to “1300”.

  In the following, description will be made assuming that the winning data number W is 80 in the real shot data table of FIG. 9 as the latest (current). The number X of winning shots corresponding to a winning number W of 80 is 1280. When 500 is subtracted from the number of shots X, 1280−500 = 780. In the real shot data table, 757 corresponds to the number X of winning shots when the number X is 780 or less. The winning number W corresponding to the case where the winning number X is 757 is 46. Accordingly, the memory where the winning number W is 45 and the winning number X is 757 or less is deleted. In other words, by this process, the past 500 pieces of data of the number of game balls fired X from the latest are stored in the table, and the number of shots X is always from the latest (current) to the past 500 pieces. The winning rate is calculated based on the retroactive data.

  The launch speed of a game ball of a general pachinko gaming machine is about 100 per minute. When the number of shots is 500, when the game ball is continuously fired, the firing time corresponds to about 5 minutes.

  As shown in the flowchart of FIG. 8, the winning rate Q is incremented by one to the value obtained by subtracting the minimum value from the maximum value of the number of winnings W stored at the time of starting the change of the symbol on the display unit H. It can be calculated. In other words, if the maximum of the “present” winning number W is 80, the minimum winning number W stored is 781 for the past 500 shots X, and this winning number W is 47. Therefore, the winning rate is (80−47 + 1) = 34. The meaning of this numerical value is the total number of game balls that have won the starting winning device from the present (that is, the point where the winning number W is 80) until the past number of fired X is 500. The higher the higher the winning rate, the lower the value, the lower the winning rate.

  Next, the details of the winning number firing number storage process (S6) will be described. As shown in the flowchart of FIG. 7, the number of shots is first stored in the number of shots address (S10). The number of fires at this time is the number of fires at the time of winning. Next, an initial number storage number address at the time of winning is set (in the present embodiment, it is set to 0000H), and this is set as the number of addresses at the time of winning fired storage (S11).

  A value obtained by subtracting a predetermined value (in this embodiment, the winning rate is determined from the memory data for the past 500 shots of the game ball to be 500) from the “number of shots” counted in S3 of FIG. Is set as a “comparison value” (S12).

  It is determined whether or not the content of the number-of-fires storage address at S11 is equal to or less than the “comparison value” of S12 (S13), and if it is equal to or less than the “comparison value” (Y), +2 is set to the number-of-incidence firing number address S14). On the other hand, when the content of the incident number firing address at S11 exceeds the “comparison value” at S12 (N), the “number of winning firing number storage address” is set, and this is set as the “transfer source address”. (S15).

  Next, the “starting number storage initial address at the time of winning” is set, and this is set as the “transfer destination address” (S16). Here, from the predetermined number for memorizing the predetermined winning (in this embodiment, it is set so as to be able to memorize 200 winnings for 200 game balls, and is set to 200), the “number of winning firing number storage address” is subtracted. Is set as the “number of transfer bytes” (S17).

  The “number of transfer bytes” set in S17 is set as the “number of fired addresses” (S18). "Launch number address" is incremented by 1 and this is set as "winning number address" (S19). Block transfer (S19) is performed. The contents of the “transfer source address” set in S15 are overwritten on the “transfer destination address” set in S16. In this process, “transfer destination address” and “transfer source address” are incremented by 1, and overwriting is repeated for the “number of transfer bytes” set in S17. As a result of this processing, only the stored data relating to the 500 winnings from the past are stored. The previous stored data is overwritten and disappears.

  Next, details of the variation pattern setting process (S9) of FIG. 6 will be described with reference to FIG. As shown in the flowchart of FIG. 11, first, as the big hit determination process, it is determined whether or not the current symbol variation is a big hit (S50). If it is a big hit (Y), the number symbol that appears on the display unit is determined by the big hit symbol random number, and one variation pattern is set from a plurality of variation patterns that become a big hit by the effect distribution random number. Processing is performed (S51). Whether or not it is a big hit has already been determined by extracting a big hit determination random number before the variation pattern setting process.

  In the big hit determination process of S50, if it is not a big hit (N), it is determined whether the probability is changing (S52). If the probability change is in progress (Y), one effect pattern is set from the effect patterns in the probability change as the probability change effect setting process (S53). For example, if the production pattern during probability fluctuation is reach, it is a fluctuation pattern of loss reach, and if it is not reach, a fluctuation pattern for shortening probability fluctuation time is set.

  In the determination process of whether or not the probability change is in S52, if it is not the probability change (N), it is determined whether or not it is a reach (S54). If it is reach (Y), as a reach production setting process (S55), one variation pattern is set from among the variation patterns that become outlier reach. Whether or not it is reach has already been determined by extracting reach determination random numbers before the variation pattern setting process.

  If it is determined that the reach is not reach in S54 (N), whether or not the winning rate calculated by the winning rate calculating process in S8 in FIG. 6 is 33 or more (whether it is less than 33) ) Is determined (S56). If the winning rate is 33 or more (Y), the predetermined value is set to “2” (S57). This predetermined value is a value used in the process of S61 described later.

  In the determination process of whether or not the winning rate in S56 is 33 or more, if the winning rate is not 33 or more (N), it is determined whether or not the winning rate is 25 or more (less than 25) ( S58). If the winning rate is 25 or more (Y), the predetermined value is set to “3” (S59). This predetermined value is a value used in the process of S61 described later.

  If it is determined in S58 whether or not the winning rate is 25 or more (N), the predetermined value is set to “4” (S60). This predetermined value is a value used in the process of S61 described later.

  After the predetermined value of the number of reserved balls is set in the processing of S57, S59, or S60, it is determined whether or not the current number of reserved balls is equal to or greater than the predetermined value (S61). Here, when the current number of reserved balls is less than a predetermined value (N), normal fluctuation is set (S63). On the other hand, when the current number of reserved balls is equal to or greater than a predetermined value (Y), a shortened variation with a short variation time is set (S62).

  In addition, the predetermined value of the number of reserved balls is determined to be any one of 2-4. If “2” is selected as the predetermined value for the number of held balls, the fluctuation pattern is normally changed when the current number of held balls is 1, and when the current number of held balls is 2 to 4, The variation pattern is a shortened variation.

  In the above embodiment, the upper limit of the number of reserved balls is set to 4, but when the upper limit of the number of held balls is set to 6, for example, the predetermined value “3” of S59 in FIG. 11 is set to “4” or “5”, The predetermined value of S60 can be set to 6. Further, the variation time of the shortening variation of the above embodiment may be divided into two stages, and a plurality of variation patterns having different variation times may be set as the variation pattern of the shortening variation according to the predetermined value.

  In the present embodiment, since the number of game balls won in the start winning device 22 is used as a winning rate with 500 shot game balls as a reference, the shot game balls are not released until 500 are fired since the power is turned on. It will be less than 500. During the period from when the power is turned on until 500 shots are released, a constant fluctuation is used regardless of the fluctuation time selection means for selecting a fluctuation pattern having a fluctuation time corresponding to the winning rate obtained by the winning rate measuring means. The pattern may be selected, but as shown below, virtual data for 500 launching game balls is prepared, the winning rate is measured using this virtual data, and the variation pattern is selected. Can be used.

  As an example of specific virtual data, FIG. 10 shows a virtual data table of the number X of winning shots and the number W of winnings when the power is turned on. When this virtual data is used, since the value obtained by adding 500 to the value of the number of shots in the actual shot data is used as the number of shots, the actual number of shots is the 501st in the data, the actual number of shots The second is used as 502 on the data. Therefore, even if the number of shots is 500 or less in practice, as shown in FIG. 9 in the data, the number of shots X at the time of winning, which is the number of shots when the game ball wins the start winning device 22, is 500 or more. The value is used as data, and virtual data is used for the number X of winning shots of 500 or less. The virtual data table in FIG. 10 is determined by assuming that six start winning devices 22 have been won for every 100 shots X, and that numerical values have been determined on the assumption that there have been winnings at almost regular intervals.
