Hereinafter, an embodiment in which the present invention is embodied in a pachinko gaming machine will be described with reference to FIGS.
An effect display device 11 having a liquid crystal display type image display unit GH is disposed at substantially the center of the game board 10 of the pachinko gaming machine. The effect display device 11 includes a symbol variation game that is performed by varying a plurality of symbol sequences (three columns in this embodiment), and various display effects executed in association with the game are displayed as images. In the present embodiment, in the symbol variation game of the effect display device 11, a symbol combination including a plurality of columns (three columns in the present embodiment) is derived. Note that the symbol variation game of the effect display device 11 is performed using decorative symbols (effect symbols) for diversifying display effects. A 7-segment special symbol display device 12 is disposed at the lower left of the effect display device 11. In the special symbol display device 12, a symbol variation game is displayed in which a plurality of types of special symbols are varied and displayed. The special symbol is a notification symbol indicating the result of the internal lottery (big hit lottery) whether or not the big hit.

  The effect display device 11 displays a display result corresponding to the display result of the special symbol display device 12. Specifically, when a big hit symbol (hit display result) that can recognize a big hit is confirmed and stopped on the special symbol display device 12, the big hit symbol (hit display result) is also confirmed and stopped on the effect display device 11. Is displayed. In addition, when a special symbol display device 12 that can recognize a deviation is displayed in a fixed stop state, the special symbol display device 12 is also displayed in a fixed stop manner.

  The jackpot symbol that is confirmed and stopped on the effect display device 11 is composed of symbol combinations in which the decorative symbols in all the rows are the same symbol. In addition, the off-line symbols that are confirmed and displayed on the effect display device 11 are a combination of symbols in which the decorative symbols in all the rows are different, or a decorative symbol in which the decorative symbols in one row are different from the decorative symbols in the other two rows. It is comprised by the following symbol combination.

  A normal symbol display device 13 is arranged on the left side of the special symbol display device 12. In the normal symbol display device 13, a normal symbol variation game (hereinafter simply referred to as a “general symbol game”) is performed in which a plurality of types of normal symbols are varied to derive one normal symbol. In the normal symbol display device 13 of this embodiment, a light-emitting body (LED, lamp, etc.) not shown is covered with a lens cover (in FIG. 1, the surface is decorated with “◯ (circle)” and “× (batsu)”). And a plurality of (two in the present embodiment) ordinary symbol display units. The normal symbol display device 13 displays the lottery result of the internal lottery (lottery per lottery to be described later) for whether or not to win a general symbol separately from the jackpot lottery to determine whether or not to win.

  Below the effect display device 11, a start winning port 14 having a game ball entrance 14a is disposed. The start winning opening 14 is an ordinary electric accessory, and includes an opening / closing blade 15 as an opening / closing mechanism that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown). The start winning opening 14 is opened by the opening operation of the opening / closing blade 15 so that the game ball can be easily entered (winning), while the opening is not expanded by the closing operation of the opening / closing blade 15. The ball is in a closed state where it is difficult to enter (win). A start port switch SW1 (shown in FIG. 2) for detecting a game ball that has entered the ball is disposed behind the start winning port 14. The start winning opening 14 can provide a start condition for the symbol variation game and a payout condition for game balls as a predetermined number (for example, three) of the winning balls by detecting the game balls that have entered.

  Also, on the right side of the effect display device 11, a special prize opening (special electric accessory) as a special prize opening provided with a special prize opening door 16 that opens and closes by the operation of an actuator (solenoid, motor, etc.) not shown. 17 is disposed. A count switch SW2 (shown in FIG. 2) for detecting a game ball that has entered the ball is disposed in the back of the big winning opening 17. The big winning opening 17 can give a payout condition of game balls as a predetermined number (for example, 10) of winning balls by detecting the gaming balls that have entered. The big winning opening 17 is opened by the opening operation of the big winning opening door 16 during the big hit game, thereby allowing a game ball to enter. For this reason, during the big hit game, the player can obtain a chance to win a prize ball.

  Note that the big hit game is a big hit lottery win, and is started after the big hit symbol is confirmed and stopped in the special symbol display game of the special symbol display device 12 and the game ends. When the big hit game is started, an opening effect indicating the start of the big hit game is first performed. After the opening effect is finished, the round game in which the big prize opening door 16 of the big prize opening 17 is opened is performed a plurality of times with a predetermined number of rounds as a predetermined upper limit (15 rounds in this embodiment). One round game is from the opening of the grand prize opening door 16 of the big prize opening 17 until it is closed. During a single round game, a predetermined number (the upper limit number of balls entered) It is released until 9 game balls enter (for example, 9) or until a specified time (round game time, for example, 25 seconds) elapses. In round games, round effects are performed. Then, an ending effect indicating the end of the jackpot game is performed, and the jackpot game is ended.

  Further, a normal symbol operation gate (hereinafter simply referred to as “gate”) 18 is disposed on the left side of the effect display device 11. A normal symbol variation switch SW3 (shown in FIG. 2) for detecting a game ball that has entered and passed is disposed at the back of the gate 18. The gate 18 can give only the start condition of the usual game when the game ball passes. In the pachinko gaming machine according to the present embodiment, the lottery condition is that the game ball has passed through the gate 18 (the normal symbol variation switch SW3 detects the game ball), and the start winning opening 14 is opened and closed when the lottery condition is satisfied. The lottery per drawing is internally performed as an open lottery for determining whether or not the opening / closing blade 15 to be operated is operated from the closed state to the open state.

  In the game board 10, an unillustrated obstacle (for example, a game nail) is disposed between the big prize opening 17 and the start prize opening 14, and the obstacle is over the effect display device 11. Thus, the game ball flowing down to the right is configured not to win the start winning opening 14 or the gate 18. Similarly, the pachinko gaming machine according to the present embodiment is configured such that game balls flowing down the left side of the effect display device 11 do not win the big prize opening 17. In other words, the start winning port 14 is arranged at a position different from the flow path of the game ball to the big winning port 17 on the game board 10.

  Note that the pachinko gaming machine of the present embodiment is equipped with a launching handle (not shown) on the front side of the gaming machine as viewed from the player. In the present embodiment, the game ball can be launched by turning the launch handle, and the strength can be set. For this reason, in this embodiment, when the player operates the launch handle to launch the game ball aiming at the big prize opening 17, the game ball is difficult to win the start prize opening 14 or the gate 18. Yes. On the other hand, in this embodiment, when the player operates the launch handle to launch the game ball aiming at the start winning opening 14 or the gate 18, it becomes difficult for the game ball to win the big prize opening 17. ing.

  Further, the pachinko gaming machine according to the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function. The probability changing function is a function for giving a probability changing state in which the winning probability (lottery probability) of the big hit lottery is changed from a low probability to a high probability after the big hit game ends. In the present embodiment, in the probability variation state, a big hit occurs until the probability variation upper limit number (300 times in the present embodiment) of the symbol variation game ends, or before the probability variation upper limit number is reached. Until then. The probability variation state can be an advantageous state for the player because the winning probability of the jackpot lottery fluctuates with a high probability and the jackpot is likely to occur.

  Further, the pachinko gaming machine according to the present embodiment has a function of shortening the variation time (hereinafter referred to as “variation shortening”). The variable speed function is a function for shortening the fluctuation time of the normal game and giving a variable state for changing the winning probability (lottery probability) of the lottery per normal map based on the passage of the gate 18 from a low probability to a high probability. It is. Further, during the variable speed state, the total opening time of the open / close blades 15 based on the fact that one lottery per lottery has been won becomes longer than that during the non-changeable state.

  In this embodiment, the variable state is given after the big hit game is over until the predetermined maximum number of symbol variation games is finished, or until the big hit is generated before the upper limit number is reached. In the present embodiment, 300 times equal to the probability variation upper limit number are set as the upper limit number of times to give the variable state. For this reason, in this embodiment, the variable state is provided from the time when the probability variation state is imparted to the end of the probability variation state (shown in FIG. 3A).

Next, the control configuration of the pachinko gaming machine will be described with reference to FIG.
A main control board 30 as a control means for controlling the entire pachinko gaming machine is mounted on the back side of the machine. The main control board 30 executes various processes for controlling the entire pachinko gaming machine and outputs various control commands (control commands) according to the process results. An effect control board 31 is mounted on the back side of the machine. The effect control board 31 controls the operation of various effect devices based on the control command output by the main control board 30.

Hereinafter, specific configurations of the main control board 30 and the effect control board 31 will be described.
The main control board 30 has a main control CPU 30a that executes control operations in a predetermined procedure, a main control ROM 30b that stores a control program for the main control CPU 30a, and a main control CPU that can write and read necessary data. A RAM 30c is provided. The main control CPU 30a is connected so that various switches SW1 to SW3 can detect and output detection signals from the game balls. Also, a special symbol display device 12 and a normal symbol display device 13 are connected to the main control CPU 30a.

  Connected to the main control board 30 (main control RAM 30c) is a backup power source B as backup means for storing and holding the game state of the pachinko gaming machine when the power is cut off in the main control RAM 30c even after the power is cut off. . The backup power source B is composed of, for example, an electric double layer capacitor and is equipped in a pachinko gaming machine. Further, the main control board 30 (main control CPU 30a) has a RAM clear switch R as an erasing means operated when erasing (clearing) the gaming state of the pachinko gaming machine stored and held in the main control RAM 30c. It is connected. The RAM clear switch R is disposed on the back side of the pachinko gaming machine as viewed from the player, and can be operated only by a store clerk who can access the back side of the pachinko gaming machine.

  When the main control CPU 30a of the main control board 30 inputs a power-off signal (a signal indicating that the voltage value has dropped to a predetermined voltage value) from a power supply monitoring circuit (not shown), the main control board 30 executes a backup process, The information stored in the control RAM 30c is retained even after the power is shut off. The information stored and retained in the main control RAM 30c even after the power is cut off includes information on the gaming state (presence / absence of a probable change state and a change state, the number of grants described later, etc.) at the time of power interruption.

  When power is turned off when the RAM clear switch R is not operated, the main control CPU 30a changes the state of the pachinko gaming machine based on the information stored in the main control RAM 30c when the power is shut off. Return to the gaming state and start control. On the other hand, when power is restored (powered on) while the RAM clear switch R is operated, the main control CPU 30a performs various settings based on the initialization information and starts control of the pachinko gaming machine.

  Further, the main control CPU 30a performs a random number update process (random number generation process) for updating the values of various random numbers such as a big hit determination random number, a special symbol distribution random number, and a universal hit determination random number every predetermined cycle. Run. The big hit determination random number is a random number used in the big hit lottery (big hit determination). The random number for special symbol distribution is a random number used to determine the jackpot symbol of the special symbol when winning in the jackpot lottery. The random number for determination per common figure is a random number used in lottery per common figure (determination per common figure). The main control RAM 30c stores (sets) various pieces of information (random numbers, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine.

  The main control ROM 30b stores a main control program, various determination values (a big hit determination value and a normal hit determination value), and a plurality of types of variation patterns. The variation pattern is a pattern that serves as a base for effects (display effects, light-emitting effects, sound effects) from the start of the symbol variation game to the end of the symbol variation game. The time (variation time) can be specified.

  The jackpot determination value is a determination value used in the jackpot lottery, and is determined from numerical values that can be taken by the jackpot determination random number (all 600 integers from 0 to 599). The big hit judgment value is a non-probability change judgment value (low probability big hit judgment value) used in a non-probability change state big hit lottery, and a probabilistic change judgment value (high probability big hit judgment value) used in a big hit lottery in the probability change state. ) The set number of determination values for probability variation (three in this embodiment) is set larger than the number of determination values for non-probability variation (two in this embodiment). According to such a setting, as shown in FIG. 3A, the probability of winning in the big hit lottery in the non-probable change state is 2/600, while the probability of winning in the big win lottery in the probabilistic state is It becomes 3/600.

  Further, the base map determination value is a determination value used in the base map lottery, and is determined from numerical values that can be determined by the base map determination random number (total of 233 integers from 0 to 232). In addition, the determination value per common figure is used in the non-variable determination value (low-probability normal value determination value) used in the lottery per non-variable state and in the lottery per general map in the variable state. There is a judgment value for variable speed (a judgment value per common figure at high probability). The set number of change determination values (232 in this embodiment) is set larger than the set number of non-change determination values (231 in this embodiment). According to such a setting, as shown in FIG. 3B, the probability of winning in the lottery per ordinary figure in the non-variable state becomes 231/233, while the probability per common figure in the variable state. The probability of winning in the lottery is 232/233.

Next, the effect control board 31 will be described.
The effect control board 31 has an effect control CPU 31a that executes control operations in a predetermined procedure, an effect control ROM 31b that stores a control program for the effect control CPU 31a, and an effect control that can write and read necessary data. A RAM 31c is provided. The effect display device 11 is connected to the effect control CPU 31a. The effect control ROM 31b stores various image data (image data such as symbols, backgrounds, characters, characters, etc.). In addition, various information (timer value, flag, etc.) that is appropriately rewritten during the operation of the pachinko gaming machine is stored (set) in the effect control RAM 31c.

  Hereinafter, various processes such as a special symbol input process and a special symbol start process executed by the main control CPU 30a of the main control board 30 based on the main control program will be described. In the present embodiment, the main control CPU 30a executes various processes such as a special symbol input process and a special symbol start process every predetermined control cycle (for example, 4 ms).

First, the special symbol input process will be described.
The main control CPU 30a determines whether or not a game ball has entered the start winning opening 14 based on whether or not a detection signal is input from the start opening switch SW1. When this determination result is affirmative, the main control CPU 30a determines whether or not the special figure start pending storage number stored in the main control RAM 30c is less than the upper limit number of four. When the number of special figure start hold storage is not less than 4, the main control CPU 30a ends the special symbol input process. On the other hand, when the special figure start hold memory number is less than 4, the main control CPU 30a increments the special figure start hold memory number by one (1).

  Next, the main control CPU 30a reads out and acquires various random number values (in this embodiment, the value of the big hit determination random number and the special symbol distribution random number) from the main control RAM 30c, and obtains these values. It is set in a predetermined storage area of the main control RAM 30c corresponding to the figure start pending storage number. Thereafter, the main control CPU 30a ends the special symbol input process.

Next, the special symbol start process will be described.
The main control CPU 30a determines whether or not the symbol variation game is being executed or whether the big hit game is being executed. When the determination result of the execution condition determination is affirmative, the main control CPU 30a ends the special symbol start process.

  On the other hand, when the determination result of the execution condition determination is negative (not in the symbol variation game and not in the big hit game), the main control CPU 30a has the special figure start pending storage number stored in the main control RAM 30c. It is determined whether or not it is larger than “0 (zero)”. When the special figure start reserved memory number is “0 (zero)”, the main control CPU 30a ends the special symbol start process because there is no symbol changing game being held. On the other hand, if the special figure start reserved memory number is 1 or more, the main control CPU 30a decrements the special figure start reserved memory number by -1 (1 subtraction) because there is a symbol variation game that is on hold. Then, the main control CPU 30a reads the value of the jackpot determination random number stored in a predetermined storage area of the main control RAM 30c in association with the special figure start pending storage number.

  Subsequently, the main control CPU 30a determines whether or not the current gaming state is an uncertain change state. The determination as to whether or not the non-probability change state is made based on the set value of a game state flag (probability change flag described later) stored in the main control RAM 30c. When the current gaming state is a non-probability change state, the main control CPU 30a compares the read jackpot determination random number value with the non-probability change determination value, and determines whether or not it matches the non-probability change determination value. do. If the result of the determination as to whether or not the non-probability variation state is negative, the main control CPU 30a compares the read jackpot determination random number value with the probability variation determination value and matches the probability variation determination value. Whether or not to hit the jackpot. When the determination result of the big hit determination is affirmative, the main control CPU 30a executes a big hit fluctuation process for causing the symbol fluctuation game to be a big hit fluctuation. Note that the big hit variation is an effect developed so that the symbol change game finally displays the big hit symbol in a fixed stop state.

  In the big hit variation process, the main control CPU 30a reads the value of the special symbol distribution random number stored in the main control RAM 30c, and based on the read value of the special symbol distribution random number, the special symbol display device The jackpot symbol is determined as a special symbol to be confirmed and stopped. In this embodiment, some special symbols (one type of [1] in this embodiment) among the special symbol jackpot symbols that can be displayed on the special symbol display device 12 do not give a certainty change state after the jackpot game ends ( It is defined as a special symbol for non-probable big hits. On the other hand, the remaining special symbols (one type of [2] in the present embodiment) of the special symbol jackpot symbols are defined as special symbols for probability variation jackpots that give a probability variation state after the jackpot game ends. In the big hit variation processing, the main control CPU 30a uses the special symbol big hit symbol for the special symbol for the non-probable variation big hit ([1] in the present embodiment) and the special symbol for the odd variation big hit ([2] in the present embodiment). Either is determined with equal probability (50%). According to such a setting, as shown in FIG. 3A, 50% of cases where a big hit is won in the big hit lottery (when affirmative determination is made in the big hit determination) becomes a positive probability big hit, and the remaining 50% is non-probable. A big hit. As described above, in the present embodiment, when the big win is won in the big win lottery, the main control CPU 30a determines whether or not to give the probable change state after the big hit game by determining the special big hit symbol. It has become. Further, the main control CPU 30a which has determined the special symbol jackpot symbol selects and determines the variation pattern for the big hit variation. Thereafter, the main control CPU 30a ends the special symbol start process.

  On the other hand, when the determination result of the big hit determination is negative, the main control CPU 30a recognizes the deviation from the fact that the value of the big hit determination random number is not a big hit value. For this reason, the main control CPU 30a executes a deviation variation process for causing the symbol variation game to be a variation variation. Note that the deviation variation is an effect developed so that the symbol variation game finally displays the symbols to be confirmed and stopped. In the deviation variation process, the main control CPU 30a determines a deviation symbol as a special symbol to be confirmed and stopped on the special symbol display device 12, and selects and determines a variation pattern for deviation variation. Thereafter, the main control CPU 30a ends the special symbol start process.

  The main control CPU 30a that has determined the special symbol and the variation pattern in the special symbol start process outputs the control command generated according to the determination items to the effect control board 31 (effect control CPU 31a) at a predetermined timing. Specifically, the main control CPU 30a first outputs a variation pattern designation command instructing a variation pattern and instructing the start of the symbol variation game at the start of the symbol variation game. The main control CPU 30a outputs a special symbol stop symbol designating command for designating the special symbol, and then outputs the variation pattern designating command. Then, the main control CPU 30a outputs a symbol stop command for instructing the end of the symbol variation game (determination of symbol determination) when the variation time determined in the instructed variation pattern has elapsed, as the variation time elapses. .

  Next, a normal symbol input process and a normal symbol start process executed by the main control CPU 30a for the normal symbol will be described. In the present embodiment, the main control CPU 30a executes various processes such as a normal symbol input process and a normal symbol start process every predetermined control period (for example, 4 ms). In the present embodiment, the main control CPU 30a that executes processing related to the following normal symbols functions as an open lottery means and an open / close control means.

First, the normal symbol input process will be described.
The main control CPU 30a determines whether or not a game ball enters (passes) the gate 18 based on whether or not a detection signal is input from the normal symbol variation switch SW3. When the determination result is affirmative, the main control CPU 30a determines whether or not the normal figure start suspension storage number stored in the main control RAM 30c is less than the upper limit number of four. When the normal figure start hold storage number is not less than 4, the main control CPU 30a ends the normal symbol input process. On the other hand, when the usual figure start hold memory number is less than 4, the main control CPU 30a increments the usual figure start hold memory number by one (1).

  Next, the main control CPU 30a reads out and acquires the value of the random number for determination per base drawing from the main control RAM 30c, and stores the value in a predetermined storage area of the main control RAM 30c corresponding to the number of temporary start pending storage. Set. Thereafter, the main control CPU 30a ends the normal symbol input process.

Next, the normal symbol start process will be described.
The main control CPU 30a executes a general drawing execution condition determination as to whether or not the normal game is being executed or whether the open / close blade 15 is in an open / close operation. When the determination result of the normal symbol execution condition determination is affirmative, the main control CPU 30a ends the normal symbol start process.

  On the other hand, if the determination result of the general map execution condition determination is negative (not during the general game and the open / close blade 15 is not in the open / close operation), the main control CPU 30a stores the general control CPU 30a stored in the main control RAM 30c. It is determined whether or not the figure start pending storage number is larger than “0 (zero)”. When the number of stored general-purpose drawings is “0 (zero)”, the main control CPU 30a ends the normal symbol start process because there is no pending general-purpose game. On the other hand, if the number of normal start reserved memory is 1 or more, the main control CPU 30a decrements the number of general start reserved memory by −1 (1 subtraction) because there is a general game on hold. Then, the main control CPU 30a reads the random number value for determination per base map stored in a predetermined storage area of the main control RAM 30c in association with the general-use starting reserved storage number.

  Subsequently, the main control CPU 30a determines whether or not the current gaming state is a non-changeable state. The determination as to whether or not the state is the non-variable state is made based on a set value of a game state flag (an operation flag described later) stored in the main control RAM 30c. When the current gaming state is the non-variable state, the main control CPU 30a compares the read random number for determining per common figure with the non-variable determination value, and matches the non-variable determination value. Judgment is made for each pass. On the other hand, if the result of determination as to whether or not the state is the non-variable state is negative, the main control CPU 30a compares the read random number value for determining per common figure with the variable determination value, It is determined whether or not it matches with the determination value. When the determination result of the normal hit determination is affirmative, the main control CPU 30a executes a normal hit change process for executing the normal game having a hit change. The hit variation is an effect that is developed so that the normal game finally displays the winning symbol in a fixed stop state. In the normal symbol variation process, the main control CPU 30a determines a winning symbol as a normal symbol to be displayed on the normal symbol display device 13 with a fixed stop.

  On the other hand, when the determination result of the normal figure hit determination is negative, the main control CPU 30a recognizes the deviation from the fact that the random number for normal figure hit determination is not a winning value. For this reason, the main control CPU 30a executes a deviation fluctuation process for causing the usual game to be out of fluctuation. Note that the deviation variation is an effect developed so that the usual game finally displays the symbols to be confirmed and stopped. In the deviation variation process, the main control CPU 30a determines a deviation symbol as a normal symbol to be displayed on the normal symbol display device 13 with a fixed stop.

  The main control CPU 30a, which has determined the normal symbol to be confirmed and stopped in the normal game, determines the variation pattern for the normal symbol that specifies the variation time of the general game according to the current gaming state. Specifically, the main control CPU 30a uses a variation pattern that specifies 2 seconds as the variation time when the current gaming state is the non-variable state, and 1 second as the variation time when the current gaming state is the variable state. Select and determine the specific variation pattern. By selecting a variation pattern having different variation times according to the gaming state, the variation time of the normal game is shortened during the variation state. Then, the main control CPU 30a that has determined the variation pattern for the normal symbol ends the normal symbol start process.

  Subsequently, the main control CPU 30a, which has determined the normal symbol variation pattern, causes the normal symbol display device 13 to execute the general symbol game in accordance with the variation pattern. Then, the main control CPU 30a, when the variation time determined in the variation pattern for the normal symbol elapses, if the affirmative determination (winning the lottery per common symbol) is made in the normal symbol determination, the determined winning symbol is the normal symbol. A fixed stop display is displayed on the display device 13. On the other hand, if the main control CPU 30a makes a negative determination in the normal symbol determination (the lottery per universal symbol is not won), the determined symbol is displayed on the normal symbol display device 13 with a fixed stop.

  As shown in FIG. 3 (b), when the affirmative determination is made in the base symbol determination (the lottery per base symbol is won), the main control CPU 30a is the one after the end of the base game in which the hit variation occurs (the symbol of the base symbol). After the confirmation stop display), the open / close blade 15 is opened / closed according to the operation pattern that differs according to the current game state.

  When the current gaming state is a non-changeable state, the main control CPU 30a opens and closes the opening / closing blade 15 for the first opening time (1.2 seconds in this embodiment) for the first number of times (twice in this embodiment). , Make it open. In the non-variable state, 1 second is set as the interval time, and the closed state is maintained until 1 second elapses between each opening operation. Therefore, according to the operation pattern in the non-changeable state, the total opening time based on one win in the lottery per common figure is set to 2.4 seconds.

  On the other hand, when the current gaming state is the variable state, the main control CPU 30a sets the opening / closing blade 15 to the second opening time (0.3 seconds in this embodiment) a second number of times (10 times in this embodiment). Open for a minute. In the non-changing state, 3 seconds are set as the interval time, and the closed state is maintained until 3 seconds elapse between the opening operations. Therefore, according to the operation pattern in the variable speed state, the total opening time based on one win in the lottery per ordinary figure is set to 3.0 seconds. Thus, by controlling the opening operation of the opening / closing blades 15 according to different operation patterns according to the gaming state, the total opening time of the opening / closing blades 15 becomes longer during the variable speed state.

  As described above, in this embodiment, the winning probability of the big hit lottery is set to be approximately the same probability as the probability variation state (3/600) and the non-probability variation state (2/600) to which the probability variation state is not given. Yes. For this reason, in the present embodiment, the probability variation state is a slightly advantageous gaming state compared to the non-probability variation state from the viewpoint of the probability of winning the big hit lottery.

  In the present embodiment, the winning probability (232/233) of the lottery per ordinary figure in the variable state is compared with the winning probability (231/233) of the lottery per non-variant state. Slightly higher. For this reason, in the present embodiment, the winning probability of the lottery per normal map is set to be substantially the same probability in the variable state and the non-variable state, and in any of the variable state and the non-variable state Winning lottery per ordinary figure with a very high probability. For this reason, in the present embodiment, from the viewpoint of the probability of winning the lottery per regular drawing, the variable state is a slightly advantageous gaming state compared to the non-variable state.

  In this embodiment, the variation time (1 second) of the usual game during the variable state is shortened compared to the variation time (2 seconds) of the normal game during the non-variable state. For this reason, in this embodiment, from the viewpoint of improving the number of executions of the usual game per unit time (so-called time efficiency), the variable state is regarded as an advantageous game state compared to the non-variable state. Yes.

  Further, in the present embodiment, the total opening time (3.0 seconds) based on one win in the lottery per ordinary figure in the variable state is the one win in the lottery per non-variable state. Longer compared to the total opening time based (2.4 seconds). For this reason, in this embodiment, from the viewpoint of the length of the total opening time, the variable state becomes an advantageous gaming state compared to the non-variable state.

  Further, in the present embodiment, the opening time of one opening / closing blade 15 is set to 1.2 seconds when the gaming state is the non-changing state, while 0.3 times when the gaming state is the changing state. Is set to seconds. In general, in a pachinko gaming machine, it is possible to launch 100 game balls per minute (that is, one ball every 0.6 seconds) by operating the launch handle. For this reason, when the opening time of the opening / closing blade 15 is set to 0.3 seconds (that is, in a variable state), the opening time of the opening / closing blade 15 is shorter than the launch interval of the game balls. Therefore, it is difficult to improve the ease of entering the start winning opening 14 by opening the opening / closing blade 15. On the other hand, when the opening time of the opening / closing blade 15 is 1.2 seconds (that is, in the non-variable state), the opening time of the opening / closing blade 15 is longer than the game ball firing interval. Since it is time, the ease of entering the start winning opening 14 can be improved by opening the opening / closing blade 15.

  In particular, in the present embodiment, the start winning opening 14 is disposed below the effect display device 11 in the game board. In general, a large number of obstacles (for example, game nails) are arranged on the game board, and a part of the game ball launched aiming at the start winning opening 14 reaches the vicinity of the starting winning opening 14. Just do it. Also from this point of view, the operation pattern in the non-variable state in which the opening time of the opening / closing blade 15 is set to be long is variable from the viewpoint of the level of difficulty of entering the game ball into the start winning opening 14. The operation pattern is more advantageous to the player than the operation pattern in the state. In this embodiment, the operation pattern of the opening / closing blade 15 in the variable state is a disadvantageous operation pattern, and the operation pattern of the opening / closing blade 15 in the non-variable state is an advantageous operation pattern. Further, in this embodiment, the non-changeable state is an easy-to-enter state where the game ball can easily enter the start winning opening 14, and the variable state enters the start winning opening 14 more than the non-variable state. It becomes difficult to enter the ball.

  In the non-variable short state, the cycle time from the start of the normal game to the end of the opening / closing operation of the open / close blade 15 is 5.4 seconds based on one win in the normal drawing lottery. On the other hand, in the variable state, the cycle time from the start of the normal game to the end of the opening / closing operation of the open / close blade 15 is 31 seconds based on one win in the normal drawing lottery. For this reason, the actual number of times of the usual game played per unit time (the number of times of lottery per common figure) is larger in the non-changed state than in the changed state. In the present embodiment, the total opening time of the opening / closing blades 15 occupying each cycle time is longer in the non-changing state than in the changing state. Specifically, in the non-varying state, the total opening time of the opening and closing blades 15 occupying 5.4 seconds of the cycle time is 2.4 seconds (about 44%), whereas in the varying state, the cycle time is The total opening time of the opening and closing blades 15 occupying 31 seconds is 3 seconds (about 10%). That is, the non-changed state in the present embodiment can also be grasped as an improved entrance rate state in which the entrance rate at which the game ball enters the start winning opening 14 is improved as compared to the changed state.

  In the easy entry state (increased entry rate state), it is easier to enter the game ball into the start winning opening 14 than in the difficult entry state, so the start condition and the payout condition of the winning ball are acquired. It becomes easy to do. For this reason, in the easy-to-enter state (increased entrance rate state), the player can acquire the starting condition of the symbol variation game without significantly reducing the game balls as possession balls, so that the game can be continued advantageously. Can do.

Next, processing executed by the main control CPU 30a regarding the gaming state after the big hit game is finished will be described.
When the main control CPU 30a gives the probability change state after the big hit game, the probability control flag and the operation flag stored in the main control RAM 30c are set to “1”, and the effect control CPU 31a is in the probability change state. The probability change command to be displayed and the operation command to indicate the change state are output. In addition, when the main control CPU 30a outputs the probability change command and the operation command, the main control CPU 30a stores the main control RAM 30c in the number of times of giving the number of remaining symbol variation games to which the probability change state and the short state are given. The probability variation upper limit number (300 times in this embodiment) is set. The main control CPU 30a decrements the number of grants by −1 (1 subtraction) every time the symbol variation game is executed. Further, when the number of times of grant reaches “0”, the main control CPU 30a sets “0” to the probability variation flag and the operation flag after the symbol variation game ends, and the effect control CPU 31a is in a non-probability variation state. And a non-actuating command indicating non-changing state are output.

  On the other hand, the main control CPU 30a sets “0” to the probability variation flag and the operation flag and sets the number of grants to “0” when the probability variation state is not imparted after the big hit game ends. Then, the main control CPU 30a outputs a non-probability change command and a non-operation command to the effect control CPU 31a. Further, the main control CPU 30a sets the probability variation flag, the operation flag, and the number of operations to “0” at the start of the big hit game. Thus, during the big hit game, the non-probable change state and the non-change short state are set. Therefore, in the present embodiment, “0” is set to the probability variation flag and the operation flag during the easy-to-enter state (entrance rate improvement state).

Next, various processes executed by the effect control CPU 31a of the effect control board 31 based on the sub-control program will be described.
When the change control designation command is input, the effect control CPU 31a selects the image display data based on the effect contents (variation contents) corresponding to the change pattern designated by the command. In addition, when the stop control designation command for special symbols is input, the effect control CPU 31a generates a decorative symbol to be confirmed and stopped on the effect display device 11 according to the command. More specifically, the effect control CPU 31a generates a jackpot symbol as a decorative symbol when a special symbol is designated as a special symbol, and also deviates from the decorative symbol when a special symbol is designated as a special symbol. Generate a symbol. Then, the effect control CPU 31a controls the display contents of the effect display device 11 so as to display an image of the symbol variation game based on the image display data, and generates a symbol stop command when a symbol stop command is input during the symbol variation game. The decorated symbol is displayed on the effect display device 11 in a fixed stop state, and the symbol variation game is terminated.

  Next, the operational effects of the pachinko gaming machine of the present embodiment configured as described above will be described based on FIG. 4 with a focus on changes in the gaming state. Note that the “game *** (“ *** ”indicates a number)” shown in FIG. 4 is a symbol that was played after power recovery (power-on) with the operation of the RAM clear switch R, or after the big hit game ended. Shows the number of floating games.

  FIG. 4A shows a situation in which a symbol variation game is played after the big hit game based on the non-probable big hit. As shown in FIG. 4 (a), after winning the jackpot game based on the non-probable bonus game, if the winning game is the 129th symbol variation game, the winning game will be the 129th symbol variation game after the bonus game ends. The gaming state during the big and big hit games is “non-probable change state + non-change state”. For this reason, in this embodiment, since the opening / closing blade 15 operates in an advantageous operation pattern from the end of the big hit game based on the non-probable big hit until the end of the 129th symbol variation game and during the big hit game, it is easy to enter the ball. It becomes a state.

  Further, after the big hit game G1 based on the probability change big hit, the “probable change state + short change state” is given as the game state. Therefore, it is difficult to enter the ball from the end of the big hit game G1 until the end of the 300th symbol variation game. In the present embodiment, since the winning probability of the big hit lottery in the probability variation state is set to 3/600 of the almost same probability as the non-probable variation state, the probability variation upper limit number of times is 300 without winning in the big hit lottery. The possibility that the symbol variation game will end is relatively high. Then, when the 300th symbol variation game is completed without winning the big hit from the end of the big hit game G1, the probability variation state and the variable state are terminated, and the game state is “non-probability variable state + non-variable state”. Is done. For this reason, in this embodiment, after the big hit game G1 based on the probability variation big hit, the transition from the difficult entry state to the easy entry state (increased entry rate state) is triggered by the end of the 300th symbol variation game. Will be. As described above, in the easy-to-enter state (entrance rate improvement state), the player can continue to play the game advantageously because the starting condition of the symbol variation game can be acquired without significantly reducing the game balls as possession balls. be able to. For this reason, in this embodiment, a player who has not won a big hit even after 300 symbol variation games is given the right to continue the game until he wins a big hit while suppressing borrowing of rental balls. You can feel as if you were done. After that, when winning the probable big hit in the 303th symbol variation game, the big hit game G2 is performed after the 303th symbol variation game is over.

  Next, FIG. 4B shows a situation where the power is shut off and the RAM clear switch R is operated when the power is turned on (power recovery) when the gaming state is “probable change state + shortening state”. Show.

  As shown in FIG. 4B, when the power is cut off during the execution of the 129th symbol variation game after the end of the big hit game based on the probability variation big hit, the main control RAM 30c performs the game by the backup process described above. The state flag (probability change flag and operation flag) and the value of the number of times of grant are stored and retained (backed up) even after the power is turned off.

  Thereafter, when the pachinko gaming machine is turned on (recovered) with the operation of the RAM clear switch R, the main control CPU 30a determines the probability change flag and the flag based on the initialization information stored in the main control ROM 30b. “0” is set in the operation flag, and “0” is set as the number of times of grant. Thereafter, the main control CPU 30a starts various processes such as the special symbol input process and the special symbol start process described above. For this reason, when the power is turned on with the operation of the RAM clear switch R, “non-probable change state + non-change state” is given as the game state, and the easy-to-enter state (entrance rate improving state) is set. . For this reason, in the present embodiment, when the store clerk of the game store operates the RAM clear switch R, it is possible to intentionally set the “non-probable change state + non-change state” as the game state. As described above, the gaming state of “probability change state + shortening state” has a high probability of hitting, but is difficult to enter, while the gaming state of “non-probability state + non-shortening state” has a low probability of big hit. It is easy to enter (increase in entrance rate). In other words, the “probability change state + shortening state” and “non-probability change state + non-change state” are each given different profits. Therefore, in this embodiment, the store clerk of the game store can intentionally set which profit is provided to the player by operating the RAM clear switch R.

  In addition, if a pachinko gaming machine is equipped with a state notification lamp for notifying a gaming state (whether it is a probable variation state) for a certain period after the power is turned on (for example, until the first symbol variation game is started), It is also possible to select different game states according to the player's preference.

Therefore, according to the pachinko gaming machine of the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the movement pattern of the opening / closing blade 15 shifts from an unfavorable movement pattern to an advantageous movement pattern when a predetermined variation upper limit number of symbol variation game is completed (the probability variation state is terminated). Is done. In this embodiment, since the operation pattern of the opening / closing blade 15 is shifted from the disadvantageous operation pattern to the advantageous operation pattern, it becomes easy to allow the game ball to enter the start winning opening 14, so the start condition of the symbol variation game The state is shifted to a state where it is easy to acquire the (entrance easy state). For this reason, in this embodiment, even when the symbol variation game with the maximum probability variation number is performed without winning in the big hit lottery (the probability variation state is finished), the player is motivated to continue the game. Can do.

  (2) In the present embodiment, the total opening time based on one winning in the lottery per ordinary figure is more favorable for the unfavorable motion pattern during the probability variation state than for the advantageous motion pattern during the non-probability variation state (non-variable short state). I made it longer. For this reason, with respect to the total opening time of the open / close blades 15, the operation pattern of the open / close blades 15 in the probability variation state (variable state) is partially higher than the operation pattern of the open / close blades 15 in the non-probability variation state (non-variable state). Can be handled advantageously. Therefore, the interest of the player in the probable state can be enhanced.

  (3) In the present embodiment, the start winning port 14 is arranged at a position different from the flow path of the game ball to the big winning port 17 on the game board 10. For this reason, during the big hit game, the game ball can be preferentially entered into the big winning opening 17 by firing the gaming ball aiming at the big winning opening 17.

  (4) In particular, in the present embodiment, during the big hit game, the game state is controlled to be “non-probable change state + non-change short state”, thereby making it easy to enter the game (increase in the entrance rate). For this reason, for the game store side, the game balls launched aiming at the big winning opening 17 win the starting winning opening 14, so that more game balls than the planned quantity are paid out as winning balls. Can be suppressed. In addition, for a player, the game ball launched aiming at the big winning opening 17 wins the starting winning opening 14, and thus it becomes difficult to win the upper limit number of gaming balls in one round game. Can be suppressed.

  (5) Also, the jackpot probability in the probability variation state and the non-probability variation state is set to substantially the same probability, so that the possibility of winning in the jackpot lottery before the end of the symbol variation game with the maximum probability variation number is reduced. For this reason, in this embodiment, it is possible to increase the possibility that the player can be provided with a situation in which the opening / closing blade 15 operates in an advantageous operation pattern (a state in which a player can easily enter a ball). In addition, the number of times of execution of the symbol variation game (probability upper limit number of times) until the easy entry state (entrance rate improvement state) is given is set to a high number of times to make it easy to enter the easy entry state. The interest of the player when the easy ball state is given can be further enhanced.

  (6) In this embodiment, the “non-probable change state + non-change state”, which is the initial state based on the initialization information, is the easy entry state. For this reason, by operating the RAM clear switch R when the power is turned on (power recovery), it is possible to intentionally set the easy-to-enter state (increase in the entrance rate) to the pachinko gaming machine.

In addition, you may change the said embodiment as follows.
-In the said embodiment, you may change suitably the winning probability of the jackpot lottery in a probability variation state, and the winning probability of the jackpot lottery in a non-probability variation state.

In the above embodiment, the ratio between the probability variation jackpot and the non-probability variation jackpot may be changed as appropriate, and the probability variation jackpot may be configured with a probability of 100%.
-In the said embodiment, you may provide multiple types of big hits from which the probability variation upper limit frequency differs. For example, 100 symbol variation games, 500 symbol variation games, or the like can be set as the probability variation upper limit number according to the type of special symbol. By comprising in this way, a variation can be given to the timing which transfers to a entering easy state from a difficult entering state, and a player's interest can be heightened.

  -In the said embodiment, you may change suitably the structure of an advantageous operation pattern and an unfavorable operation pattern. For example, in each operation pattern, the opening time, interval time, and opening frequency of the opening / closing blade 15 may be changed to different times and times.

  -In the said embodiment, you may change suitably arrangement | positioning of the start winning opening 14 and the big winning opening 17 in the game board 10. FIG. That is, the start winning opening 14 and the big winning opening 17 are positions where it is difficult for the game ball to win the other winning opening when a game ball is launched aiming at either the starting winning opening 14 or the large winning opening 17. What is necessary is just to be arrange | positioned.

  In the above embodiment, a sub-control board such as a display control board for controlling the effect display device 11 and a sound control board for controlling the speaker is provided, and a sub-control board that controls each sub-control board is provided. The present invention may be embodied in a pachinko gaming machine or a pachinko gaming machine provided with a single control board that integrally has the functions of the main control board 30 and the effect control board 31.
