Description

  The present invention releases a winning means that allows a game ball to enter after the symbol variation game is completed when a predetermined jackpot display result is displayed in a symbol variation game performed by varying a plurality of symbols. The present invention relates to a gaming machine in which a big hit game composed of round games is performed.

  Conventionally, in a pachinko gaming machine which is a kind of gaming machine, a random number for determining a big hit is obtained when a game ball enters a start winning device arranged on the gaming board, and the value of the random number is determined in advance. Depending on whether or not the big hit determination value matches, the big hit lottery of whether or not the big hit is done. In addition, the lottery result of the big hit lottery is derived by executing a symbol variation game in which a plurality of columns of symbols are displayed on the effect display device. In the symbol variation game, the player can recognize the jackpot if it is a jackpot symbol that has been finally stopped.

  In such a pachinko gaming machine, the background image is displayed on the effect display device for the purpose of diversifying the effect, and the interest of the effect during the symbol variation game is improved. In addition, there is a type that has a plurality of types of background images and changes (switches) the type of the background image at a predetermined timing (for example, Patent Document 1). In Patent Document 1, on the condition that the number of executions of the symbol variation game with the same type of background image is greater than or equal to a predetermined number, a switching lottery is executed as to whether or not to change the type of the background image (switching), The type of the background image is changed with the winning of the switching lottery. As a result, in Patent Document 1, the number of times the symbol variation game is executed with the same type of background image is set to be at least a predetermined number (for example, 20 times) or more. That is, the symbol variation game with the same type of background image is continued at least a predetermined number of times. In this way, frequent changes (switching) of the background image are suppressed.

JP 2007-44307 A

  By the way, some pachinko machines equipped with multiple types of background images suggest the degree of expectation (whether the jackpot expectation) that the symbol variation game will be a big hit when the background image changes (when switching). There is a gaming machine that performs a notice effect. In such a gaming machine, the big hit expectation is varied depending on the contents of the notice effect. For example, there is a case where the color of the notice effect with a high degree of expectation of jackpot is “red” and the color of the notice effect with a low degree of expectation of big hit is “blue”.

  In such a pachinko gaming machine, when the change (switching) of the background image is suppressed as in Patent Document 1, the frequency of the notice effect is suppressed. That is, when the number of times the symbol variation game is executed with the same type of background image is not equal to or greater than the predetermined number, the background image does not change (does not switch), and thus the notice effect is not executed. In other words, if the number of times the symbol variation game is executed with the same type of background image is equal to or greater than the predetermined number and if the symbol variation game has a high jackpot expectation level, the notice effect with a high jackpot expectation level is not executed. Therefore, the frequency at which the notice effect with a high expectation level for the big hit is executed is very low.

  The present invention has been made paying attention to such problems existing in the prior art. Its purpose is to prevent frequent switching of the background image and to actively execute a notice effect that is executed together with the switching of the background image when a symbol variation game with a high expectation level of jackpot is executed. It is to provide a game machine that can be used.

In order to achieve the above object, the invention according to claim 1 is a display means for displaying a symbol variation game performed by varying a plurality of types of symbols when a winning ball is detected by the winning detection means. In a gaming machine to which a jackpot game is provided in which a special winning means is opened and closed when a background image is displayed on the display means and a predetermined jackpot display result is displayed in the symbol variation game When the symbol variation game is started, a jackpot determination unit that determines whether or not the symbol variation game is a big hit, and if the determination result of the jackpot determination unit is negative, it is determined whether or not a reach effect is executed. Based on the determination results of the reach determination means and the jackpot determination means and the reach determination means, a plurality of types of variation patterns that can at least specify the effect time of the symbol variation game are specified. For each symbol variation game, a variation pattern determination unit that determines from among the dynamic patterns, an effect determination unit that determines whether or not the variation pattern determined by the variation pattern determination unit is a specific variation pattern including a specific effect content, and The background switching lottery means for executing switching lottery for determining whether or not to switch the type of the background image, and the background switching lottery means for selecting a plurality of types of background images to be displayed. A background determination unit that selects and determines one from the background, and a background control unit that displays the background image on the display unit during the symbol variation game when the background image is determined by the background determination unit; The content of the notice effect for which the symbol variation game is expected to become a big hit is determined, and the effect of the notice effect of the decided effect content is determined by the background control. The notice effect execution means to be executed in the symbol variation game for switching the background image according to the stage, the counting means for counting the number of times of the symbol variation game executed with the same type of background image, A number of times determination means for determining whether or not a predetermined minimum number of times has been reached, and the variation pattern determination means does not include the specific effect content when the determination result of the jackpot determination means is affirmative While determining the specific variation pattern with a higher probability than the normal variation pattern, when the determination result of the jackpot determination means is negative, the normal variation pattern is determined with a higher probability than the specific variation pattern, and the announcement effect execution If the determination result of the effect determination means is affirmative, the means is a big hit period with a higher probability than a normal notice effect with a low degree of expectation of jackpot While determining the execution of the special notice effect with a high waiting time, when the determination result of the effect determination means is negative, it is configured to determine the execution of the normal notice effect with a higher probability than the special notice effect, the background When the number of executions counted by the counting unit is determined not to reach the minimum number by the number determination unit, the determination unit has won the switching lottery when the determination result of the effect determination unit is affirmative , The background image is determined, while the determination result of the effect determination unit is negative, the background image is not determined regardless of the winning result of the switching lottery, the number of executions counted by the counting unit is Until it is determined that the minimum number of times has been reached, even if the determination result of the effect determination means is negative, the background switching lottery means executes the switching lottery, If it wins a replacement lottery, the and the history information indicating that won switching lottery adapted to store data when the number of executions in which the counting means has counted by said count determination means has reached the minimum number of If the history information is stored and held, the background image is determined, while if the history information is not stored and held, the selection lottery is won regardless of the determination result of the effect determination means. The gist of this is to determine the background image.

  According to the present invention, the background image is prevented from being frequently switched, and when the symbol variation game with a high expectation degree of big hit is executed, the notice effect that is executed together with the background image switching is actively executed. be able to.

Hereinafter, an embodiment in which the present invention is embodied in a pachinko gaming machine (hereinafter referred to as a “pachinko machine”) which is a kind of gaming machine will be described with reference to FIGS.
In FIG. 1, the front side of the pachinko gaming machine 10 is schematically shown. On the front side of the opening of the outer frame 11 that forms the outline of the machine body, a vertical rectangular inner frame 12 for setting various gaming components is provided. It is assembled to be openable and detachable. On the front side of the middle frame 12, a front frame 14 having a glass frame on which a protective glass for protecting the game board 13 disposed inside the machine is mounted and an upper ball tray 15 are opened and closed in a laterally open state. It is assembled as possible. In addition, a decorative lamp 16 as a light-emitting device that performs a light-emitting effect is generated on the front side of the front frame 14 and the game area 13a of the game board 13 by light emission (lighting (flashing)) of a light-emitting body (LED, lamp, etc.). Is provided. In addition, a speaker 17 serving as a sound output unit that outputs various sounds and performs a game effect based on the sound output is disposed below the outer frame 11. A lower ball tray 18 and a launching device 19 are attached to the lower part of the middle frame 12. Then, when the player operates the launching device 19 to drive the launching device 19, the game ball in the upper ball tray 15 is launched into the game area 13 a of the game board 13.

  In the lower right of the game area 13a of the game board 13, a special figure display H1 as a 7-segment display is arranged. In addition, the center role 20 disposed in the approximate center of the game area 13a of the game board 13 includes a variable display H2 as a liquid crystal display type display means. As shown in FIG. 2, the variable display H <b> 2 is provided in the center of the center accessory 20. The special symbol display H1 executes a symbol variation game in which a plurality of types of symbols are varied and displayed. In the variable display H2, a display effect related to the symbol variation game performed in the special figure display H1 is performed. Specifically, the variable display H2 performs a display effect based on a fluctuating image (or image display), and changes a plurality of types of symbols in a plurality of columns to display a symbol combination game (hereinafter referred to as a symbol). May be shown as a combination game).

  Then, in the symbol variation game, the special symbol display H1 displays a special symbol by varying a plurality of types of special symbols (hereinafter, sometimes referred to as “special symbols”) in one row. This special figure is a notification pattern indicating the result of an internal lottery such as whether or not a big hit. On the other hand, in the display effect related to the symbol variation game, the variable display H2 varies a plurality of types of decorative symbols (hereinafter sometimes referred to as “decorative diagrams”) in a plurality of columns (in this embodiment, three columns). A decorative drawing is displayed for each column. This decorative drawing is an effect design used for diversifying display effects.

  On the special symbol display H1, the symbol variation display is started simultaneously with the start of the symbol variation game, and the special symbol is confirmed and stopped simultaneously with the end of the game. In addition, the variable display H2 starts the decorative display of the decorative drawing at the same time as the start of the symbol changing game, and the decorative drawing is temporarily stopped and displayed in a swinging and changing state before the end of the game. The decoration drawing is displayed in a fixed stop state. “Fluctuation display” is a state in which the type of the symbol displayed in the display area defined in the indicator that displays the symbol is changing. “Temporary display” means that the symbol is shaken in the display area. This is a state displayed in a fluctuating state. The “definite stop display” is a state in which the symbols are fixed and stopped in the display area. In the special symbol display H1 and the variable display H2, the display effect relating to the symbol variation game and the symbol variation game is started at the same time and is ended at the same time (that is, the special symbol and the decorative drawing are simultaneously displayed in a fixed stop).

  In this embodiment, one special figure corresponding to the lottery results of the big hit lottery and the small lottery lottery is selected from a plurality of special figures (106 kinds in this embodiment) for the special figure display H1. The selected special figure is individually displayed in a fixed stop state at the end of the symbol variation game. The 106 types of special charts are 100 types of big hit symbols (corresponding to the big hit display result) that can recognize big hits, and five types of small hit symbols (small hit display results) that can be used to recognize small hits. )) And is classified into one type of off-symbol that can be recognized as a symbol. The small hit lottery is performed when the big hit lottery is not won. When the jackpot symbol is displayed, the player is given a jackpot game. Further, when the small hit symbol is displayed, the player is given a small hit game. The big hit game and the small hit game of this embodiment will be described in detail later.

  In the present embodiment, the variable display H2 includes [1], [2], [3], [4], [5], [6], [7], [8], [ 9] is displayed as a decorative drawing. In the present embodiment, the variable display H2 has a larger display area than the special figure display H1, and the decorative drawing is displayed much larger than the special figure. . For this reason, the player can recognize the big hit or miss from the symbol combination stopped and displayed on the variable display H2. When the symbols of all columns stopped and displayed on the variable display H2 are of the same type, the big hit can be recognized from the symbol combination ([222] [777] or the like). The symbol combination that can recognize this jackpot is a jackpot symbol combination (big hit display result) by a decorative drawing. When the big hit symbol combination is displayed in a fixed stop state, the player is given a big hit game after the end of the symbol variation game. On the other hand, when the symbols of all columns displayed on the variable display H2 are stopped and displayed are of different types, or when the symbols of one column are different from the symbols of the other two columns, the symbol combination ([123] [122] [757] etc.) can be recognized. The symbol combination which can recognize this deviation becomes a symbol combination (outlier display result) of the deviation by the decorative drawing. In addition, a predetermined symbol combination ([191] [212] [323] [434] [545] [656] [767] [878] [989] in the present embodiment) is displayed among the symbol combinations out of place. In some cases, it can be recognized that either a small hit game or a big hit game may be awarded. The symbol combination that can recognize the small hit game or the big hit game is a symbol combination that suggests a probability variation state in which a probability variation state in which the probability of the big hit determination is low probability to high probability is given.

  Further, in the present embodiment, each row in the variable display H2 is configured such that the decorative drawing is variably displayed along a predetermined variation direction (vertical scroll direction) when the symbol variation game is started. When the symbol variation game is started (when the decorations in each column start to vary), the left column (left symbol) → the right column (right symbol) → the middle column (middle) as viewed from the player side in the variable display H2. The decorative illustrations are temporarily stopped and displayed in the order of symbols. When the left symbol and the right symbol that are once stopped and displayed are of the same type, the reach state can be recognized from the symbol combination ([↓] indicates that the symbol is changing, such as [1 ↓ 1]). In the reach state, among the plurality of columns, the decorative drawings of the specific columns (in this embodiment, the left column and the right column) are temporarily displayed as the same type, and columns other than the specific column (in this embodiment, This is a state in which the decorative drawing in the middle row is variably displayed. The symbol combination which can recognize this reach state becomes the symbol combination of the reach by the decorative drawing. Further, in the pachinko gaming machine 10 of the present embodiment, after the start of the symbol variation game, the left column that temporarily stops the decorative drawing is the first stop display column, and then the right that temporarily stops the decorative drawing is displayed. The column becomes the second stop display column, and finally the middle column for temporarily displaying the decorative drawing is the third stop display column.

  The variable display H2 displays a symbol combination corresponding to the display result of the special figure display H1. More specifically, the symbol combination of the special symbol display H1 and the symbol combination of the variable display H2 correspond to each other. When the symbol variation game ends, the symbol combination of the special symbol and the symbol combination of the decorative symbol are combined. Correspondingly, a fixed stop is displayed. For example, when the big hit symbol is confirmed and stopped on the special symbol display H1, the big hit symbol combinations such as [222] and [444] are also fixedly stopped and displayed on the variable indicator H2. . Further, when the off symbol is stopped and displayed on the special symbol display H1, the off symbol combination such as [151] and [345] is also displayed on the variable indicator H2 in a fixed stop manner. In addition, the symbol combination of the decorative drawing with respect to the special drawing is not necessarily one-to-one, and the symbol combination with one decorative drawing is selected from among the symbol combinations with a plurality of decorative drawings for one special drawing. Yes.

  As described above, in the variable display H2 of the present embodiment, the display effects (the three rows of symbols are changed) related to the symbol variation game (the symbol variation game in which one row of symbols is variably displayed) performed on the special symbol display H1. A symbol variation game that displays a combination of symbols is displayed.

  Further, as shown in FIG. 2, a normal symbol display H10 composed of two LEDs is disposed at the lower right of the game board 13 (on the right side of the special figure display H1). In this normal symbol display H10, a symbol combination game (hereinafter referred to as “general symbol game”) that derives one common symbol by varying a plurality of types of ordinary symbols (hereinafter sometimes referred to as “common symbol”). Is sometimes displayed). In this embodiment, two types of common maps are shown in the light emission mode of two LEDs. Specifically, two types of common maps are displayed by turning on both upper LEDs and only the upper LED. Show.

  The player can recognize a normal hit or a loss from a symbol (display result derived in the general game) finally displayed in the general game. In the case of the light emission mode in which the two LEDs of the normal symbol display H10 are both turned on, the normal hit can be recognized. The usual figure which can recognize this normal hit becomes the display result of the normal hit. When the normal hit display result is displayed, the normal hit game is given to the player. In addition, when the two light emitting modes of the normal symbol display H10 are light emitting modes in which only the upper LED is lit, it is possible to recognize a deviation from the usual figure. The usual figure which can recognize this detachment becomes a display result of detachment.

  Further, as shown in FIG. 2, a first start winning device 21 as a winning detection means having a first starting entrance 21a through which a game ball can always enter is disposed below the center accessory 20. Has been. Behind the first start winning device 21, a first start port sensor SW1 (shown in FIG. 4) for detecting a game ball that has entered is provided. The first start winning device 21 can give a start condition for the symbol variation game when a game ball is entered. Further, below the first start winning device 21, an opening / closing operation is performed by opening and closing the second starting entrance 22a through which a game ball can enter and an ordinary electric accessory solenoid SOL2 (shown in FIG. 4). A second start winning device 22 is provided as a winning detection means provided with an opening / closing blade (ordinary electric accessory) 22b as a mechanism. FIG. 2 shows the opening / closing blade 22b in a closed state.

  Behind the second start winning device 22, a second start port sensor SW2 (shown in FIG. 4) for detecting a game ball that has entered is provided. The second start winning device 22 can give a start condition for the symbol variation game when a game ball is entered. The second starting entrance 22a of the second starting winning device 22 is always closed with the open / close blade 22b closed. In a state in which the second starting entrance 22a is closed, the second starting winning device 22 is in a state where it is not possible to enter (a state in which entering is restricted). Then, when the predetermined opening condition is satisfied, the second starting entrance 22a is operated from the closed state to the open state by opening and closing the blades 22b, so that the opening time is predetermined once or a plurality of times. Opened. In a state where the second starting entrance 22a is opened, the second starting winning device 22 is in a state in which it is possible to enter a ball (a state in which a ball is allowed to enter).

  Further, as shown in FIG. 2, a big prize opening device having a big prize opening door 24 that opens and closes by the operation of a big prize opening solenoid SOL <b> 1 (shown in FIG. 4) below the second start winning prize device 22. 23 (special winning means) is provided. Behind the big prize opening device 23, a count switch SW3 for detecting a game ball that has entered is provided. When a big hit game or a small hit game is generated, the big prize opening device 23 is opened by the opening operation of the big prize opening door 24 so that a game ball can be entered. Can get a chance to win.

  Further, the pachinko gaming machine 10 of the present embodiment stores the number of game balls that have been won when the game balls have won the respective start winning devices 21 and 22, and the number of reserved start balls (the number of reserved memories). It is stored inside the machine (RAM 30c of the main control board 30). The number of reserved memories accumulated when the symbol variation game is being performed indicates the number of symbol variation games being held (waiting for symbol variation game). The number of reserved memories is incremented by 1 when a game ball is awarded to each of the start winning devices 21 and 22, and is decremented by 1 when the symbol variation game is started. Therefore, when a game ball wins each start winning device 21, 22 during the symbol variation game, the reserved memory number is further added and accumulated up to a predetermined upper limit number (four in this embodiment). Yes. Then, as shown in FIG. 2, in the lower right part of the game board 13 (on the right side of the special figure display device H1), there is a reserved memory for informing the player of the number of symbol variation games that are pending based on the number of reserved memories. A number display portion L is provided.

  The reserved memory number display portion L is configured by a light emitting means including a plurality of (four in the present embodiment) LEDs of the hold lamp L1, the hold lamp L2, the hold lamp L3, and the hold lamp L4. A player is notified of the number of symbol variation games on hold by the number of lighting of the respective holding lamps L1 to L4. For example, when only the hold lamp L1 is lit, it indicates that one symbol variation game is being held, and when all the hold lamps L1 to L4 are lit, four symbol variation games are displayed. Indicates that it is pending.

  At the end of the symbol variation game, if the big hit game or the small hit game is not started and there is no reserved memory number (0 (zero)), the symbol variation game is not being performed (variation) Is stopped). In other words, the standby state waits for the start of the next symbol variation game where the symbol variation game is interrupted. The stand-by state is continued until the end condition is satisfied with the start condition of the symbol variation game being satisfied during the stand-by state once the start-up state occurs.

  An operation gate 25 is disposed on the left side of the center accessory 20. Behind the operation gate 25, a gate sensor SW4 (shown in FIG. 4) for detecting a winning (passing) game ball is provided. The actuating gate 25 can give the start condition for the usual game when the winning of the game ball is detected (passage detection). The usual game is an effect performed for deriving a lottery result as to whether or not the opening / closing blade 22b is opened. When the game per game is given, it becomes easy for the second start winning device 22 to win a game ball by opening the opening / closing blade 22b, and the player has a chance to easily acquire the start condition of the symbol variation game. be able to.

  In addition, as shown in FIG. 2, a normal symbol reserved memory number display unit M is disposed below the normal symbol display H10. The normal symbol reserved memory number display unit M is a display unit that displays the stored number of start reserved balls stored in the machine (RAM 30c) as a game start ball when the game ball passes through the operating gate 25, The number of times the normal game is held is notified by the display content of the symbol hold memory number display unit M.

  The reserved memory number of the usual game is incremented by 1 (+1) when the game ball passes through the operation gate 25, and is decremented by 1 (-1) when the usual game is started. Then, when the game ball passes through the operation gate 25 during the usual game, the number of reserved memories of the usual game is further added (+1) and accumulated up to a predetermined upper limit number (4 in this embodiment). The normal symbol reserved memory number display unit M is configured by a light emitting means including a plurality of (four in the present embodiment) LEDs of the hold lamp M1, the hold lamp M2, the hold lamp M3, and the hold lamp M4. The player is notified of the number of times the usual game is on hold by the number of lighting of the holding lamps M1 to M4. For example, when only the hold lamp M1 is lit, it indicates that one general game is on hold, and when all the hold lamps M1 to M4 are lit, four general games are displayed. Indicates that it is pending.

  Further, the pachinko gaming machine 10 of the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function as a special gaming state advantageous to the player after the big hit game is over. The probability change function is a low probability (normal state) of the jackpot lottery probability (winning probability) after the jackpot game ends, provided that the type of jackpot symbol (special figure) that is confirmed and stopped is a predetermined probability variation symbol. This is a function that gives a probability variation state (probability variation state) that varies from a certain normal probability (3/1223 in the present embodiment) to a high probability (30/1223 in the present embodiment). In this embodiment, a jackpot to which a probability variation state is given after the jackpot game ends is a probability variation jackpot, and a jackpot to which a probability variation state is not imparted is a non-probability variation jackpot. Further, the probability variation state is given until the next jackpot game is given. In this way, when a probability variation state is given, the probability of winning a big hit fluctuates with a high probability and it is easy for a jackpot to occur.Therefore, the probability variation state is advantageous to the player, and the player will become a probability variation big hit. Playing games while expecting.

  In addition, when the probability variation state is given, the fluctuation time of the ordinary game for deriving the lottery result of whether or not to open / close the opening / closing blade 22b is shortened, and the normal hit probability of the ordinary game is higher than the normal probability. There is a case where the entrance rate improvement state that fluctuates with probability is given as a privilege. In this improved entrance rate state, the open / close blade 22b opens and closes with an operation pattern different from that in the improved entrance rate state when winning in the usual game. In other words, when the normal game is won when the entrance rate is not improved, the open / close blade 22b is opened once, and the open state is maintained until 300 ms elapses after the open. On the other hand, in the case of winning the normal game when the entrance rate is improved, the opening / closing blade 22b is opened three times and the opened state is maintained until 1600 ms elapses after the opening in one opening. It has become. In other words, the opening / closing blade 22b has a longer total opening time when the entrance rate improved state is given, and operates more advantageously for the player than when the entrance rate improved state is not given. Is set.

  Even before the specified time has elapsed since the opening, when the upper limit number (for example, 10 balls) of game balls has entered, the opening / closing blade 22b is closed. Similarly, the opening / closing blade 22b is closed when the upper limit number (for example, 10 balls) of game balls has entered even if the ball has not been opened a predetermined number of times. Also, in this embodiment, the entrance rate improvement state is the type of probability variation symbol (big hit game) and the game state in which the symbol variation game that is a probability variation big hit was played (in this embodiment, the entrance rate improvement state Whether or not it is given is determined.

  In addition, the pachinko gaming machine 10 according to the present embodiment has a time-saving function that provides a reduced variation time (hereinafter referred to as “time reduction”) state as a special gaming state advantageous to the player after the end of the big hit game that becomes an uncertain change state. ing. When the short-time state is given, the fluctuation time of the normal game for deriving the lottery result as to whether to open / close the opening / closing blade 22b is shortened, and the hit probability of the normal game is changed from the normal probability to the high probability The improved entrance rate is given as a privilege. When the winning rate is improved, the open / close blade 22b is opened and closed with an operation pattern different from that when the winning rate is won in the usual game, as in the above-described case.

  In other words, when the normal game is won when the entrance rate is not improved, the open / close blade 22b is opened once, and the open state is maintained until 300 ms elapses after the open. On the other hand, when winning the normal game when the entrance rate is improved, the opening and closing blades 22b are opened three times, and the opened state is maintained until 1600 ms elapses after opening in one opening. It has become. That is, the opening / closing blade 22b is set to operate more advantageously for the player when the short-time state is applied than when the normal state is applied. The time-short state is given until a predetermined number of times (in this embodiment, 100 times) the symbol variation game is played, or until a big hit is generated before the number of times is reached. In the present embodiment, when a non-probable big hit is made, a time-short state may be given after the big hit game ends.

Next, the big hit game and the small hit game specified in the pachinko gaming machine 10 of the present embodiment will be described in detail with reference to FIG.
The big hit game is started after the big hit symbol and the big symbol symbol combination are confirmed and stopped on the respective displays H1 and H2 in the symbol change game 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 over, the round game in which the big prize opening device 23 (the big prize opening door 24) is opened has a predetermined number of rounds as an upper limit (in this embodiment, either 16 rounds or two rounds). Performed multiple times. One round game is performed until the grand prize opening door 24 of the grand prize opening device 23 is opened and closed a predetermined number of times. During one round game, the special prize opening device 23 has a predetermined number (the maximum number of balls to be entered). ) Until the game ball wins or until the specified time (round game time) 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.

  Then, in the pachinko gaming machine 10 of the present embodiment, when the big hit lottery is won, one big hit game is determined from the four types of big hit games shown in FIG. 3, and the determined big hit game is given. It has become. Of the four types of jackpot games, which jackpot game is awarded is determined in accordance with the type of special symbol (big jackpot symbol) that is determined when the jackpot lottery is won. In the present embodiment, 100 types of special symbol jackpot symbols displayed on the special symbol display H1 are classified into four groups of symbol A, symbol B, symbol C, and symbol D as shown in FIG. Further, in the pachinko gaming machine 10 of the present embodiment, when winning a small hit lottery, one type of small hit game shown in FIG. 3 is given, and the special figure display H1 is classified into one type as a small hit symbol. The symbol E to be displayed is displayed.

  70 kinds of big hit symbols among the big hit symbols displayed on the special symbol display H1 are distributed to the symbol A. Similarly, five types of jackpot symbols among the jackpot symbols displayed on the special symbol display H1 are distributed to the symbol B. Of the jackpot symbols displayed on the special symbol display H1, five types of jackpot symbols are assigned to the symbol C. Of the jackpot symbols displayed on the special symbol display H1, 20 types of jackpot symbols are assigned to the symbol D. Further, in the symbol E shown in FIG. 3, five types of special symbols (small hit symbols) corresponding to the small hit game are assigned.

  The jackpot game that is given when the jackpot symbol classified as symbol A is displayed on the special chart display H1, the specified number of rounds is set to "16", and the probability change state is given after the jackpot game ends It is a 16-round jackpot game. Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol A is displayed on the special symbol display H1 is referred to as “16R probability variable jackpot game”. In the 16R probability variable big hit game, the upper limit number of balls (specified number) for one round game is set to “9 balls”. Further, in the 16 round games in the 16R probability variable big hit game, the big prize opening door 24 of the big prize opening device 23 is set to “open once” in each round game. In addition, in the 16R probability variation big hit game, regardless of the game state at the time of winning the big hit lottery, the probability change state is given after the big hit game ends and the entrance rate improvement state is given until the end of the probability change state. That is, in the present embodiment, in the 16R probability variation big hit game, the probability variation state and the entrance rate improvement state are given during the maximum grant period of the probability change state with the upper limit until the next big hit game is given. Yes. In FIG. 3, a case in which a state where the entrance rate improvement is given after the probability variation state is given until the next big hit game is given is indicated as “no limit”.

  Also, in the 16R probable big hit game, the opening time is “8000 (ms)”, the round game time (specified time) of one round game is “25000 (ms)”, and the ending time is “11000 (ms)”. Are set respectively. Each round game may be terminated when a maximum number of game balls are entered. For this reason, in the 16R probability variation big hit game, “25000 (ms)” which is the round game time of one round game is the maximum time. In addition, the interval time between rounds (interval between rounds) in the 16R probability variation big hit game is set to “1000 (ms)”, and the final opening interval time (time from the end of the last round to the start of ending) is , “1000 (ms)”.

  The jackpot game that is awarded when the jackpot symbol classified as symbol B is displayed on the special chart display H1, the specified number of rounds is set to “2”, and the probability change state is given after the jackpot game ends It is a 2 round jackpot game. Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol B is displayed on the special symbol display H1 is referred to as “first 2R probability variable jackpot game”. In the first 2R probability variation big hit game, the upper limit number of balls (specified number) for one round game is set to “9 balls”. In addition, in the two round games in the first 2R probability variation big hit game, each of the round games is set so that the big prize opening device 23 (the big prize opening door 24) is opened once.

  In addition, in the first 2R probability variation jackpot game, depending on the gaming state at the time of winning the jackpot lottery, there are cases where a probability variation state and an improved entrance rate are given after the jackpot game ends, and only the probability variation state after the jackpot game ends. May be granted. Specifically, if a winning rate improvement state is not granted at the time of winning the big hit lottery, a probable state is granted after the big hit game is finished, but as a result, the winning rate improvement state is not granted, so only the probable state is given. (The entry rate improvement state is given 0 times). In other words, in the present embodiment, in the first 2R probability variation jackpot game, when the winning rate of the big hit lottery is not given, the upper limit is set until the next jackpot game is awarded only in the probability variation state unless the winning rate improvement state is given. It is given during the maximum grant period of the probability variation state. On the other hand, in the first 2R probability variable big hit game, if the winning rate improvement state is given at the time of winning the big hit lottery, the positive change state and the increased winning rate state are given after the big hit game ends.

  In the first 2R probability variation big hit game, the opening time is “400 (ms)”, the round game time of one round game is “600 (ms)”, and the ending time is “2092 (ms)”. Each is set. Note that the interval time between rounds (inter-round interval) in the first 2R probability variation big hit game is set to “1000 (ms)”, and the final opening interval time (from the end of the final round to the start of ending) Time) is set to “1000 (ms)”.

  In addition, the round game time of each round game is the maximum time because each round game may end when a maximum number of game balls enter. However, in the round game time (600 (ms)) of the first 2R probability variation big hit game, the number of game balls entering the big prize opening device 23 in one round game is equal to the upper limit number of balls entered. The time is set so as not to satisfy. Incidentally, in the pachinko gaming machine 10, the number of game balls fired per minute is set to approximately “100 balls”, so the time required to launch one game ball is “600 (ms)”. . In other words, in each round game of the first 2R probability variation big hit game, within 9 hours of round game time (600 (ms)), the game ball of “9 balls” that will be the upper limit of the number of balls to be launched is entered. It is virtually impossible.

  The jackpot game that is awarded when the jackpot symbol that is classified as symbol C is displayed on the special chart display H1, the specified number of rounds is set to “2”, and the probability change state is given after the jackpot game ends It is a 2 round jackpot game. Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol C is displayed on the special symbol display H1 is referred to as “second 2R probability variable jackpot game”. In the second 2R probability variation big hit game, the upper limit number of balls (specified number) for one round game is set to “9 balls”. Further, in the two round games in the second 2R probability variation big hit game, the big prize opening device 23 (the big prize opening door 24) is set to be opened “once” in each round game.

  In the second 2R probability variation jackpot game, depending on the gaming state at the time of winning the jackpot lottery, there are cases where a probability variation state and an improved entrance rate are given after the jackpot game ends, and only the probability variation state after the jackpot game ends. May be granted. Specifically, if a winning rate improvement state is not granted at the time of winning the big hit lottery, a probable state is granted after the big hit game is finished, but as a result, the winning rate improvement state is not granted, so only the probable state is given. (The entry rate improvement state is given 0 times). In other words, in this embodiment, in the second 2R probability variation big hit game, if the winning rate improvement state is not given at the time of winning the big hit lottery, only the probability change state is the upper limit until the next big hit game is given. It is given during the maximum grant period of the probability variation state. On the other hand, in the second 2R probability variation jackpot game, if the winning rate improvement state is given at the time of winning the big hit lottery, the probability variation state in which the probability variation state is the upper limit until the next jackpot game is awarded. Is given during the maximum grant period, while the improved entrance rate state is given during the shortest maximum grant period with an upper limit of 100 times.

  In the second 2R probability variation big hit game, the opening time is “400 (ms)”, the round game time of one round game is “600 (ms)”, and the ending time is “2092 (ms)”. Each is set. The interval time between rounds (inter-round interval) in the second 2R probability variation big hit game is set to “1000 (ms)”, and the final opening interval time (from the end of the final round to the start of ending) Time) is set to “1000 (ms)”.

  In addition, the round game time of each round game is the maximum time because each round game may end when a maximum number of game balls enter. However, in the round game time (600 (ms)) of the second 2R probability variation big hit game, the number of game balls entering the big prize opening device 23 in one round game is equal to the upper limit number of balls entered. The time is set so as not to satisfy. Incidentally, in the pachinko gaming machine 10, the number of game balls fired per minute is set to approximately “100 balls”, so the time required to launch one game ball is “600 (ms)”. . That is, in each round game of the second 2R probability variation big hit game, within the round game time (600 (ms)), it is possible to launch and enter the “9 balls” game balls, which is the maximum number of balls to be entered. It is virtually impossible.

  The jackpot game given when the jackpot symbol categorized as symbol D is displayed on the special symbol display H1, the specified number of rounds is set to “2”, and the non-probable change state ( It is a two-round big hit game in the normal state). Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol D is displayed on the special chart display H1 is referred to as “2R non-probability variation jackpot game”. In the 2R non-probable big hit game, the upper limit number of balls (specified number) for one round game is set to “9 balls”. Further, in the two round games in the 2R non-probability big hit game, the special prize opening device 23 (the big prize opening door 24) is set to be opened “once” in each round game.

  Further, in the 2R uncertain variable big hit game given when the big hit symbol classified as the symbol D is displayed, the short time state (that is, the improved entrance rate) is set according to the game state at the time of winning the big hit lottery. Whether or not it is given is different. Specifically, if the winning rate improvement state is not given at the time of winning the big hit lottery, the short time state (entry rate improving state) is not given after the big hit game ends. That is, in the present embodiment, in the 2R non-probability variable big hit game, if the winning rate improvement state is not given at the time of winning the big hit lottery, neither the probable change state nor the winning rate improved state is given. . On the other hand, if a winning rate improvement state is given at the time of winning the big hit lottery, a short time state (entry rate improving state) is given after the big hit game ends. That is, in the present embodiment, in 2R non-probability big hit game, if the winning rate improvement state is given at the time of winning the big hit lottery, the shorter time state (entry rate improving state) is shorter than 100 times. It is given during the maximum grant period of the state (entrance rate improvement state).

  In the 2R non-probable big hit game, “400 (ms)” is set as the opening time, “600 (ms)” is set as the round game time for one round game, and “2092 (ms)” is set as the ending time. Has been. In addition, the interval time between rounds (interval between rounds) in the 2R non-probable big hit game is set to “1000 (ms)”, and the final opening interval time (time from the end of the final round to the start of ending) Is set to “1000 (ms)”.

  In other words, the opening time, round game time, and ending time in the 2R non-probable big hit game are set to the same time as the opening time, round game time, and ending time of the first and second 2R probable big hit games, respectively. In addition, the opening mode of the big prize opening door 24 in the first and second 2R probability variation big hit games is the same as the opening mode of the big prize opening door 24 in the 2R non-probability big hit game.

  For this reason, it is determined which one of the first and second 2R probability variable big hit games and 2R non-probable big hit games has been awarded based on the opening state of the grand prize winning door 24, the opening time, the round game time and the ending time. I can't do that. Similarly, depending on the game state at the time of winning the big hit and whether or not the improved entrance rate is given after the end of the big hit game, the first and second 2R probable big hits are given when the improved entrance rate is not given. It is not possible to determine which of the game and the 2R non-probable big hit game has been awarded. That is, when the entrance rate improvement state is not given after the big hit game is finished, it becomes impossible to determine whether or not the probability change state is given after the first and second 2R probability change big hit games and the 2R non-probable big hit game. ing. In addition, when the entrance rate improvement state is given after the big hit game is finished, it is impossible to determine whether the first and second 2R probability change big hit games and the probability change state are given after the 2R non-probable big hit game is finished. It has become. It should be noted that, after the first 2R jackpot game is over, it is possible to determine that the game state is a probable change state only when the improved entrance rate continues for 100 times or more without winning a jackpot. .

  In the small hit game given when the small hit symbol classified as the symbol E is displayed on the special symbol display H1, the prescribed round number is set to “one time” and one round game is The upper limit number of balls (count) is set to “9 balls”. Further, in one round game of the small hit game, it is set so that the big prize opening device 23 (the big prize opening door 24) is opened “twice”. In the small hit game, the gaming state after the small hit game is continued in the gaming state at the time of winning the small hit lottery. In other words, in the small hit game, if the probability variation state is given at the time of winning the small hit lottery, the probability variation state is continuously given even after the end of the small hit lottery game, and the entrance rate improvement state is given at the time of winning the small hit lottery If it has been done, after the small hit game ends, the state of improving the entrance rate is continuously given. In addition, in the small hit game, if the winning rate improvement state is given at the time of winning the small hit lottery, the improved winning rate is continuously given after the small hit game ends. Further, in the small hit game, if the game state at the time of winning the small hit lottery is a normal state, the normal state is continued even after the small hit game ends.

  In the small hit game, “400 (ms)” is set as the opening time, and “2092 (ms)” is set as the ending time. The opening time of the first opening and the second opening is set to “600 (ms)” as an opening mode of the big winning opening device 23 (big winning opening door 24) of the round game in the small hit game, “1000 (ms)” is set as an interval time between the first opening and the second opening. The time from the closing of the second prize opening door 24 to the start of ending is set to “1000 (ms)”.

  As described above, in the small hit game where the entrance rate improvement state is not given, the time from the start of the small hit game to the end thereof is the first and second 2R probability variable big hit games and 2R non-probable big hit games. It is set to be the same as the time from the start to the end, and the opening time and interval time of the special prize opening door 24 are also the same. For this reason, it is impossible to determine which of the small hit game, the first and second 2R probability variable big hit games, and the 2R non-probable big hit game is given.

  Note that the round game time of the round game in the small hit game is the maximum time because the round game may be ended by entering the upper limit number of game balls. However, the round game time of the small hit game (2200 (ms), the actual total opening time of the big prize opening door 24 is 1200 (ms)) is a game that enters the big prize opening device 23 in one round game. The time is set such that the number of balls entered does not satisfy the maximum number of balls entered. In other words, in a round game of small hit games, it is practically impossible to launch and enter “9 balls”, which is the maximum number of balls entered, within the round game time (2200 (ms)). is there.

Next, the control configuration of the pachinko gaming machine 10 will be described with reference to FIG.
A main control board 30 that controls the entire pachinko gaming machine 10 is mounted on the back side of the pachinko gaming machine 10. The main control board 30 executes various processes for controlling the entire pachinko gaming machine 10, performs arithmetic processing on various control signals (control commands) for controlling the game according to the processing results, and outputs the control signals. (Control command) is output. In addition, an overall control board 31, a display control board 32, a lamp control board 33, and a sound control board 34 are mounted on the rear side of the machine. The overall control board 31 comprehensively controls the display control board 32, the lamp control board 33, and the sound control board 34 based on the control signal (control command) output from the main control board 30. The display control board 32 controls the display mode (display images of symbols, backgrounds, characters, etc.) of the variable display H2 based on control signals (control commands) output from the main control board 30 and the overall control board 31. The lamp control board 33 controls the light emission mode (lighting (flashing) / lighting off timing, etc.) of the decorative lamp 16 based on control signals (control commands) output from the main control board 30 and the overall control board 31. The sound control board 34 controls the sound output mode (sound output timing, etc.) of the speaker 17 based on the control signal (control command) output from the main control board 30 and the overall control board 31.

Hereinafter, specific configurations of the main control board 30, the overall control board 31, and the display control board 32 will be described.
The main control board 30 is provided with a main CPU 30a. A ROM 30b and a RAM 30c are connected to the main CPU 30a. A first start port sensor SW1, a second start port sensor SW2, a count switch SW3, and the like are connected to the main CPU 30a. The main CPU 30a is connected to a special symbol display H1, a reserved memory number display unit L, and a normal symbol reserved memory number display unit M. The main CPU 30a is connected to a special winning opening solenoid SOL1 and a normal electric accessory solenoid SOL2. The main CPU 30a is connected to a normal symbol display H10 and a gate sensor SW4. Further, the main CPU 30a updates the values of various random numbers such as a hit determination random number every predetermined period, stores (sets) the updated values in the setting area of the RAM 30c, and rewrites the values before the update. The main CPU 30a is equipped with a timer function, and measures time at a predetermined timing (for example, timing at which a symbol variation game is started). The RAM 30c stores (sets) various pieces of information (random values, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine 10.

  The ROM 30b stores a main control program for controlling the entire pachinko gaming machine 10. In addition to the main control program, a plurality of types of variation patterns (effect patterns) are stored in the ROM 30b. The variation pattern is a symbol variation game in which the symbol variation game is started by the variable indicator H2 and the special symbol display H1 after the symbol variation game is started on the variable indicator H2 and the special symbol display H1. The pattern used as the base of the game effect (display effect, light emission effect, audio | voice effect) until is complete | finished is shown. In other words, the variation pattern can specify the effect content and the effect time (the change time) of the symbol change game from when the special figure starts to change until the special figure is confirmed and stopped. The variation patterns are classified for each variation content including a hit effect (for a big hit effect or a small hit effect), an outlier reach effect, and an outlier effect (for an outlier reach effect).

  As shown in FIG. 5, the fluctuation pattern is selected for the out-of-bound effect (for the effect without out-of-reach reach) and the out-of-reach reach effect for the out-of-place effect selected in the case of a loss that has not won the big win lottery and the small win lottery. Fluctuation patterns P2 and P3. Further, the variation patterns include variation patterns P4 to P6 for winning effects that are selected when winning the big hit lottery or winning the small hit lottery.

  In the present embodiment, the variation pattern for the winning effect includes variation patterns P4 and P5 (variation pattern for the big hit effect) that are selected when the 16R probability variable big hit game is determined. In addition, the variation pattern for winning effect includes a variation pattern P6 selected when the first 2R probability variation big hit game, the second 2R probability variation big hit game, the 2R non-probability big hit game, or the small hit game is determined. is there. In the pachinko gaming machine 10 of the present embodiment, when the first and second 2R probability variable big hit games, 2R non-probable big hit games, or small hit games are determined, the same variation pattern P6 is selected. It has become. Even if any winning game among the winning games is determined, the contents of the effect of the symbol variation game are the same (same variation time).

  Note that the off-stage effect performed based on the fluctuation pattern P1 is a off-line effect that is developed so that the symbol fluctuation game finally displays the out-of-combination symbol combination without stopping through the reach effect. Further, the outlier reach effect based on the fluctuation patterns P2 and P3 is developed so that the symbol change game finally displays the final symbol combination (the outlier reach symbol combination) through the reach effect and finally stops the display. It is off-line production. The winning effect performed based on the variation patterns P4 and P5 is a winning effect that is developed so that the symbol variation game is finally subjected to reach effect, and finally a big hit symbol combination is displayed in a fixed stop state. The winning effect performed based on the variation pattern P6 is a winning effect that is developed so that the symbol variation game is subjected to the reach effect and finally the symbol combination suggesting the probability variation is displayed in a fixed stop state. In the reach production, in the symbol change game with the decorative display on the variable display H2, the combination of the reach symbols is temporarily stopped and displayed, and finally the symbol combination (the jackpot symbol combination, the symbol combination that suggests the probable change, or the outlier symbol combination). This is an effect performed until the combination) is derived. In the special symbol display H1, when the symbol variation game is started, the symbol variation is continued until the variation time elapses without performing the reach effect. Further, the off-line effect performed based on the fluctuation pattern P1 for off-line effect varies after the start of the symbol variation game according to a predetermined variation stop order (for example, left column → right column → middle column). This is an effect that stops symbols and derives symbols in each column.

  In the pachinko gaming machine 10 of the present embodiment, the fluctuation patterns P2 to P6 are accompanied by reach fluctuations. Then, based on these variation patterns P2 to P6, specific display effect contents for developing the symbol variation game are specified. Also, in this embodiment, in principle, even if the contents of the effect of the symbol variation game are visually recognized, any variation pattern until the symbol combination is finally stopped and displayed in the symbol variation game and the effect result is finally derived. The player is prevented from recognizing whether the game is a symbol variation game based on the game.

  The variation pattern P1 shown in FIG. 5 is a pattern of a loss effect that performs normal variation. Further, the variation pattern P2 is a variation pattern for an outlier reach effect that performs normal reach variation. The variation patterns P4 and P6 are variation patterns for a hit effect in which normal reach variation is performed. Further, the fluctuation pattern P3 is a fluctuation pattern for the outlier reach effect that performs the super reach fluctuation. Further, the variation pattern P5 is a variation pattern for a hit effect in which super reach variation is performed. In this embodiment, the “normal variation” means that after the symbol variation game is started, the variation of the symbols in each column is stopped according to a predetermined variation stop order (for example, left column → right column → middle column). This is an effect of deriving symbols in each column.

  Further, the normal reach variation and the super reach variation indicate the types of reach production. The normal reach fluctuation is a reach effect of the effect content that derives the decorative drawing by changing the remaining one column (in this embodiment, the middle column) after the reach symbol combination is temporarily stopped and displayed on the variable display H2. is there. Super reach fluctuation is a two-stage production of reach production. Normal reach fluctuation is executed and all rows of decorative drawings are temporarily displayed or middle rows of decorative drawings are displayed in a variable manner. For example, it is a reach effect of the effect content in which a specific character appears and shifts (develops) to “XX reach” called by the name of the appearing character to derive a decorative drawing. In the super reach variation, the normal reach variation is the first stage, and the content is developed from the normal reach variation.

  In the present embodiment, when the main CPU 30a wins the big hit lottery (when the big hit), the main CPU 30a can more easily determine the fluctuation pattern P5 for performing the super reach fluctuation than the fluctuation pattern P4 for performing only the normal reach fluctuation. On the other hand, when the main CPU 30a does not win the big hit lottery (when it is out of place) and determines to execute the reach effect, the main CPU 30a determines the variation pattern P3 for performing the super reach variation from the variation pattern P2 for performing only the normal reach variation. It is hard to do. Therefore, when the super reach fluctuation is performed, the expectation for the big hit is increased.

  Then, when the symbol variation game is performed based on the variation patterns P4 and P5, the special symbol display H1 and the variable display H2 finally display the big hit symbol and the big hit symbol combination capable of recognizing the big hit respectively. It is like that. When a symbol variation game is played based on the variation pattern P6, the big hit symbol or the small hit symbol is displayed on the special symbol display H1, and the symbol combination suggesting the probability variation is finally displayed on the variable indicator H2. It has become so. The 2R fluctuation pattern P6 is a part of the fluctuation pattern included in the fluctuation pattern distribution table for 2R production.

  Further, when the symbol variation game is performed based on the variation patterns P2 and P3 for the outlier reach effect, the symbol combination of the outlier symbol and the outlier (outlier reach) is finally obtained in the special symbol display H1 and the variable indicator H2. Is displayed. Note that the fluctuation patterns P2 and P3 for the outlier reach effect are part of the fluctuation patterns included in the fluctuation pattern distribution table for the outlier reach effect.

  In addition, when the symbol variation game is performed based on the variation pattern P1 for the offending effect, after the variation is displayed on the special symbol display device H1 and the variable display device H2, the symbol combination and the symbol combination of the deviation are finally displayed. It has become so. Note that the variation pattern P1 for the offending effect is a part of the variation pattern included in the variation pattern distribution table for the offending effect.

  In addition, the jackpot determination value is stored in the ROM 30b. The big hit determination value is a determination value used in the internal lottery to determine whether or not the big hit, and is determined from numerical values (all 1223 integers from 0 to 1222) that the random number for winning determination can take. Note that the number of jackpot determination values differs depending on whether or not the probability variation state is given, and the number of jackpot determination values in the probability variation state (30 in this embodiment) is the jackpot determination in the normal state. More than the number of values (three in this embodiment) is set. The RAM 30c stores a hit determination random number used when determining the big hit.

  In addition, the small hit determination value is stored in the ROM 30b. The small hit determination value is a determination value used in the internal lottery for determining whether or not a small hit is made, and is determined from numerical values that can be taken by random numbers for hit determination (total of 1223 integers from 0 to 1222). Note that the number of small hit determination values when the symbol variation game is played is set to 5 in the present embodiment. In addition, the random number for hit determination uses the random number used in the jackpot determination as it is. Further, the value of the small hit determination value does not differ depending on whether or not the probability variation state is given and whether or not the entrance rate improvement state is given (the same value is determined).

  The RAM 30c stores special figure distribution random numbers used when determining the type of special figure that becomes a big hit symbol when the big hit is determined. Each special figure is assigned a predetermined number (one in this embodiment) of random numbers for special figure distribution, and the main CPU 30a determines when the big hit is determined (when the big hit determination is affirmative), The jackpot symbol is determined based on the obtained special figure distribution random number. This special figure distribution random number is set to a predetermined cycle so that the main CPU 30a can take a numerical value within a predetermined numerical range (in the present embodiment, all 100 integers of “0” to “99”). Each time (every 2 ms), the numerical value is incremented by one and updated. Then, the main CPU 30a stores the updated value in the RAM 30c as the value of the special figure distribution random number, and rewrites the value of the special figure distribution random number that has already been stored. Are updated sequentially. In the present embodiment, the special figure distribution random numbers are acquired when a game ball wins each start winning device 21, 22.

  The RAM 30c stores various information (such as various random number values) that can be appropriately rewritten during the operation of the pachinko gaming machine 10. For example, the RAM 30c stores a small hit design random number used when determining the type of the special figure that becomes the small hit symbol when determining the small hit. In addition, the RAM 30c stores a random number for assigning a common figure used for determining a type of a common figure that will be a winning symbol when the ordinary game is won.

  The ROM 30b stores a normal hit determination value. The normal hit determination value is a determination value used in the internal lottery (normal win lottery) to determine whether or not the normal hit, from among the numerical values that can be taken by the normal hit determination random numbers (all 107 different integers from 0 to 106). It has been established. Note that the number of normal hit determination values varies depending on whether or not the entrance rate improvement state is given, and the number of normal hit determination values when the entrance rate improvement state is assigned (this embodiment) , 106) is set to be larger than the number of normal hit determination values (5 in this embodiment) when the entrance rate improvement state is not given (normal state). The RAM 30c stores a random number for normal hit determination used at the time of normal hit determination. In the present embodiment, the normal hit determination random number is acquired when the game ball passes through the operation gate 25.

Next, the overall control board 31 will be described with reference to FIG.
The overall control board 31 is provided with an overall CPU 31a. A ROM 31b and a RAM 31c are connected to the overall CPU 31a. The overall CPU 31a updates various random number values at predetermined intervals, stores (sets) the updated values in the setting area of the RAM 31c, and rewrites the values before the update. The ROM 31b stores an overall control program for comprehensively controlling the display control board 32, the lamp control board 33, and the sound control board 34.

In addition to the overall control program, the ROM 31b stores various tables that are referred to when determining various effects. Details of the various tables will be described later.
The general CPU 31a has a timer function, and measures time at a predetermined timing (for example, a timing at which a symbol variation game is started). The RAM 31c stores (sets) various pieces of information (random values, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine 10.

Next, the display control board 32 will be described with reference to FIG.
The display control board 32 is provided with a sub CPU 32a. A ROM 32b and a RAM 32c are connected to the sub CPU 32a. A variable display H2 is connected to the display control board 32 (sub CPU 32a). The ROM 32b stores a display control program for controlling the display contents of the variable display H2. The ROM 32b stores various image data (image data such as symbols, various background images, characters, characters, etc.). Further, the sub CPU 32a has a timer function, and measures time at a predetermined timing (for example, timing at which the symbol variation game is started). The RAM 32c stores (sets) various pieces of information (random values, timer values, flags, etc.) that are appropriately rewritten during operation of the pachinko gaming machine 10.

  Next, various processes such as a winning process and a variation pattern determination process executed by the main CPU 30a based on the main control program will be described. In the present embodiment, the main CPU 30a of the main control board 30 that executes the following various processes based on the main control program functions as a big hit determination unit, a reach determination unit, a predetermination unit, and a variation pattern determination unit.

First, the winning process will be described with reference to FIG.
The main CPU 30a determines whether or not a game ball has entered the start winning devices 21 and 22 at predetermined time intervals (every 2 ms) (step S11). That is, in step S11, the main CPU 30a determines whether or not a detection signal output when each of the start port sensors SW1 and SW2 detects a game ball is input. When the determination result is negative (when no winning is detected), the main CPU 30a ends the winning process. On the other hand, when the determination result is affirmative (when winning detection is present), the main CPU 30a determines whether or not the number of reserved storage stored in the RAM 30c is less than the upper limit (4 in the present embodiment) ( Step S12). If this determination result is negative (holding memory count = 4), the main CPU 30a ends the winning process.

  On the other hand, if this determination result is affirmative (if the number of stored storages <4), the main CPU 30a adds (+1) to the stored storage number stored in the RAM 30c (+1), and rewrites the stored storage number (step S13). ). Subsequently, the main CPU 30a reads and acquires the hit determination random number and the special figure distribution random number value from the RAM 30c, and corresponds the read hit determination random number and the special figure distribution random number value to the reserved storage number. A predetermined storage area of the attached RAM 30c is set (step S14). The hit determination random number and the special figure allocation random number are random numbers that are sequentially updated by the main CPU 30a at predetermined intervals, and the main CPU 30a sets the updated value in the setting area of the RAM 30c before the update. The value of is rewritten. Then, the main CPU 30a ends the winning process.

Next, the variation pattern determination process will be described with reference to FIG.
The main CPU 30a determines whether or not the symbols (special illustrations and decorations) are in a variable display, whether or not a small hit game is being played, and whether or not a big hit game (special game) is being performed (step S21). ). When the determination result in step S21 is affirmative (when the symbol variation game, the small hit game or the big hit game is being performed), the main CPU 30a ends the variation pattern determination process. On the other hand, when the determination result in step S21 is negative (when the symbol variation game is not being played, the small hit game is not being played, and the big hit game is not being played), the main CPU 30a determines that the number of reserved memories is less than “0” at a predetermined time interval. It is determined whether it is larger (step S22). If the determination result of step S22 is negative (when the number of stored memories = 0), there is no pending symbol variation game, so the main CPU 30a ends the variation pattern determination process.

  On the other hand, if the determination result in step S22 is affirmative (if the number of stored storages> 0), the main CPU 30a determines the value of the hit determination random number and the special figure distribution stored in the RAM 30c in association with the number of stored storages. Read the random number value. Then, the main CPU 30a determines whether or not the value of the read hit determination random number matches the jackpot determination value stored in the ROM 30b, and performs a jackpot determination (big hit lottery) (step S23). In the present embodiment, the jackpot determination value is changed depending on whether or not the probability variation state is given. In the normal state (low probability), the probability that the determination result of the jackpot determination is affirmative (the jackpot probability) is 3/1223, and in the probability variation state (high probability), the determination of the jackpot determination The probability that the result is affirmative (big hit probability) is 30/1223. Further, the main CPU 30a subtracts “1” from the reserved storage number (−1), and then obtains the value of the hit determination random number and the special figure distribution random number stored in association with the reserved storage number. It has become.

  When the determination result of the big hit determination is affirmative (in the case of a big hit), the main CPU 30a determines the special hit display symbol H1 from the big hit symbols according to the special figure based on the special figure distribution random number value read from the RAM 30c. A final stop symbol to be stopped and displayed is determined (step S24).

  Thereafter, the main CPU 30a selects a variation pattern distribution table for winning effects according to the determined type of jackpot symbol (step S25). In step S25, the main CPU 30a selects a variation pattern distribution table including a variation pattern of the 16R system when the big hit symbol is classified as the symbol A. Further, when the big hit symbol is classified into symbols B, C, and D, a variation pattern distribution table including a 2R variation pattern is selected.

  After the process of step S25, the main CPU 30a acquires a random number for distribution pattern distribution from the RAM 30c. Then, the main CPU 30a refers to the variation pattern distribution table selected in step S25, and determines a variation pattern for winning effect based on the determined final stop symbol and the acquired variation pattern distribution random number (step S26). In the present embodiment, when the jackpot symbol is classified as symbol A in step S26, one of the variation patterns P4 and P5 is determined. In step S26, when the big hit symbol is classified into symbols B, C, and D, the variation pattern P6 is determined.

  After that, the main CPU 30a that has determined the variation pattern and the final stop symbol executes various processes related to the symbol variation game, such as outputting a predetermined control command to the overall control board 31 (overall CPU 31a) at a predetermined timing (step). S27). Specifically, the main CPU 30 a first outputs a variation pattern designation command designating a variation pattern and instructing the start of symbol variation to the overall control board 31. At the same time, the main CPU 30a controls the display content of the special figure display H1 so that the special figure starts to fluctuate. Further, the main CPU 30 a outputs a special symbol designation command for designating the final stop symbol to the overall control board 31. After that, the main CPU 30a controls the display content of the special-figure display H1 so that the determined final stop symbol is displayed based on the effect time determined in the designated variation pattern. Further, the main CPU 30a instructs the central control board 31 to stop all symbols on the overall control board 31 for instructing to stop the variation of the decorative drawing based on the production time determined in the specified variation pattern and to display the symbol combination to be confirmed and stopped. Output. Thereafter, the main CPU 30a ends the variation pattern determination process.

  On the other hand, if the determination result of the big hit determination in step S23 is negative (not a big hit), the main CPU 30a determines whether or not the acquired value of the random number for hit determination matches the small hit determination value stored in the ROM 30b. Determination is made and a small hit determination (small hit lottery) is performed (step S28). In the present embodiment, the small hit determination value is constant regardless of the gaming state, and the winning probability of the small hit lottery is 5/1223.

  If the determination result in step S28 is affirmative (small hit), the main CPU 30a performs final stop displayed on the special figure display H1 from the five types of small hit symbols (design E) according to the special figure. A symbol is determined (step S29). Thereafter, the main CPU 30a selects a variation pattern distribution table for a hit effect including a 2R variation pattern. Then, the main CPU 30a acquires a random number for variation pattern distribution from the RAM 30c, refers to the selected variation pattern distribution table, and determines a variation pattern for winning effect based on the acquired variation pattern distribution random number ( Step S30). In the present embodiment, the variation pattern P6 is determined in step S30.

  The main CPU 30a, which has determined the variation pattern and the final stop symbol, proceeds to the process of step S27, and, as described above, outputs a predetermined control command to the overall control board 31 (overall CPU 31a) at a predetermined timing. Various processes relating to the game are executed, and the variation pattern determination process is terminated. After that, in a process different from the variation pattern determination process, the main CPU 30a displays the determined final stop symbol based on the effect time determined in the designated variation pattern. The display content of H1 is controlled. Further, the main CPU 30a instructs the central control board 31 to stop all symbols on the overall control board 31 for instructing to stop the variation of the decorative drawing based on the production time determined in the specified variation pattern and to display the symbol combination to be confirmed and stopped. Output.

  On the other hand, if the determination result of the small hit determination in step S28 is negative (not a small hit), the main CPU 30a performs a reach determination that determines whether or not to perform a reach effect (step S31). In this embodiment, the probability that the determination result of reach determination is affirmative (reach probability) is set to 34/241 when the number of reserved memories is 2 or less before the execution of the variation pattern start process. Further, when the number of reserved storages is 3 before the execution of the variation pattern start process, the reach probability is set to 20/241. Further, when the number of reserved memories is 4 before the execution of the variation pattern start process, the reach probability is set to 6/241.

  When the determination result of the reach determination in step S31 is affirmative (when a reach effect is performed), the main CPU 30a determines a special figure indicating a detachment as a final stop symbol (step S32). Thereafter, the main CPU 30a selects a variation pattern distribution table for the outlier reach effect including the variation pattern for the outlier reach effect. Then, the main CPU 30a obtains the variation pattern distribution random number from the RAM 30c, refers to the selected variation pattern distribution table, and determines the variation pattern for the deviation reach effect based on the obtained variation pattern distribution random number. (Step S33). In the present embodiment, in step S33, one of the variation patterns P2 and P3 is determined.

  Thereafter, the main CPU 30a proceeds to the process of step S27, and executes various processes related to the symbol variation game, such as outputting a predetermined control command at a predetermined timing to the overall control board 31 (overall CPU 31a) as described above. Then, the variation pattern determination process is terminated. After that, in a process different from the variation pattern determination process, the main CPU 30a displays the determined final stop symbol based on the effect time determined in the designated variation pattern. The display content of H1 is controlled. Further, the main CPU 30a instructs the central control board 31 to stop all symbols on the overall control board 31 for instructing to stop the variation of the decorative drawing based on the production time determined in the specified variation pattern and to display the symbol combination to be confirmed and stopped. Output.

  On the other hand, when the determination result of the reach determination in step S31 is negative (when the reach effect is not performed), the main CPU 30a determines the special figure indicating the detachment as the final stop symbol (step S34). After that, the main CPU 30a selects a variation pattern distribution table for outlier effects including a variation pattern for outlier effects. Then, the main CPU 30a acquires a random number for variation pattern distribution from the RAM 30c, refers to the selected variation pattern distribution table, and determines a variation pattern for effect production based on the acquired random number for distribution pattern distribution ( Step S35). In the present embodiment, the variation pattern P1 is determined in step S35.

  Thereafter, the main CPU 30a proceeds to the process of step S27, and executes various processes related to the symbol variation game, such as outputting a predetermined control command at a predetermined timing to the overall control board 31 (overall CPU 31a) as described above. Then, the variation pattern determination process is terminated. After that, in a process different from the variation pattern determination process, the main CPU 30a displays the determined final stop symbol based on the effect time determined in the designated variation pattern. The display content of H1 is controlled. Further, the main CPU 30a instructs the central control board 31 to stop all symbols on the overall control board 31 for instructing to stop the variation of the decorative drawing based on the production time determined in the specified variation pattern and to display the symbol combination to be confirmed and stopped. Output.

  When the main CPU 30a determines the jackpot, after the end of the symbol variation game based on the determined variation pattern, the main CPU 30a starts control of the type of jackpot game specified based on the final stop symbol, and the overall control board 31 (the overall CPU 31a). ), A predetermined control command is output at a predetermined timing. Hereinafter, the control contents executed by the main CPU 30a will be described for each jackpot game of the 16R probability variable big hit game, the first 2R probability variable big hit game, the second 2R probability variable big hit game, and the 2R non-variable big hit game.

  First, control when a 16R probability variation big hit game is awarded will be described. When the symbol variation game ends, the main CPU 30a outputs an opening command and starts measuring the opening time (8000 (ms)). Next, when the opening time elapses, the main CPU 30a outputs a round command corresponding to the first round in order to start the round game of the first round, and measures the round game time (25000 (ms) at the maximum). Start and output an open signal. Thereby, in the pachinko gaming machine 10, the big prize opening door 24 of the big prize opening device 23 is opened with the start of the first round game. The main CPU 30a outputs a closing signal when the end condition is satisfied in the first round game. Thereby, in the pachinko gaming machine 10, the big prize opening door 24 of the big prize opening device 23 is closed with the end of the first round game.

  The main CPU 30a having finished the round game of the first round, in order to start the round game of the second round, the interval time (1000 (ms)) of the interval between rounds set between the first round and the second round ), A round command corresponding to the second round is output. Then, when the end condition is satisfied in the second round game, the main CPU 30a similarly ends the second round game. Thereafter, similarly, the main CPU 30a controls the round games of the 3rd to 16th rounds. Then, when the round game of the final round ends, the main CPU 30a outputs an ending command after the elapse of the final opening interval time (1000 (ms)) and starts measuring the ending time (11000 (ms)). Then, the main CPU 30a ends the big hit game after the ending time has elapsed.

  At that time, when the 16R probability variation big hit game is awarded, the main CPU 30a sets “1” in the probability variation flag indicating that the probability variation state is imparted and also indicates that the entry rate improvement state is imparted. Set “1” in the flag. When “1” is set in the probability variation flag, it indicates that the probability variation state is assigned, and when “0” is set, it indicates that the probability variation state is not imparted. ing. Similarly, when the operation flag is set to “1”, it indicates that the entrance rate improvement state is given, and when “0” is set, the entrance rate improvement state is set. Indicates that it has not been granted. Each flag is stored in a predetermined storage area of the RAM 30c. Each flag is cleared (“0” is set) when a big hit game is awarded.

Next, the control when the first and second 2R probability variable big hit games or 2R non-probable big hit games are given will be described.
When the symbol variation game ends, the main CPU 30a outputs an opening command and starts measuring the opening time (400 (ms)). Next, when the opening time has elapsed, the main CPU 30a outputs a round command corresponding to the first round in order to start the round game of the first round, and measures the round game time (maximum 600 (ms)). Start. The main CPU 30a outputs an open signal. Then, the main CPU 30a measures the time after the grand prize opening door 24 is opened (first opening), and if the round game time (600 (ms)) has elapsed, the main round of the first round game is played. To end, a close signal is output.

  Next, the main CPU 30a measures the time from the end of the first round game. At this time, the main CPU 30a measures the interval time (1000 (ms)) of the interval between rounds set between the first round game and the second round game. Next, when the interval time has elapsed, the main CPU 30a outputs a round command corresponding to the second round in order to start the second round game, and the round game time (maximum of 600 (ms)). Start measurement. The main CPU 30a outputs an open signal. Then, the main CPU 30a measures the time after the grand prize opening door 24 is opened (second opening), and if the round game time (600 (ms)) has elapsed, the main round of the round game is played. To end, a close signal is output.

  Next, the main CPU 30a measures the time from the end of the second round game. Then, after the end of the second round game, the main CPU 30a outputs an ending command after elapse of the final opening interval time (1000 (ms)) and starts measuring the ending time (2092 (ms)). To do. Then, the main CPU 30a ends the big hit game after the ending time has elapsed.

  At that time, the main CPU 30a sets “1” to the probability variation flag when the first and second 2R probability variation big hit games are awarded, while “0” is assigned to the probability variation flag when the 2R non-probability big hit games are awarded. "Is set.

  Further, the main CPU 30a operates when the first and second 2R probability variation big hit games or 2R non-probability big hit games are awarded, and the winning rate improvement state is not given at the time of winning the big hit. Set the flag to “0”.

  In addition, the main CPU 30a operates when the first and second 2R probability variable big hit games and 2R non-probable big hit games are awarded, and when the winning rate improvement state is given when the big hit is won, May be set to “1” and an operation count indicating the number of remaining symbol variation games to which the improved entrance rate is given. Specifically, when the first 2R probability variation big hit game is awarded, the number of operations is not set. On the other hand, when the second 2R probability variation big hit game and the 2R non-probability big hit game are awarded, the number of operations is set to 100 times. The number of operations is decremented by 1 every time the symbol variation game is executed, and when the value becomes 0, the operation flag is cleared ("0" is set). Note that the number of operations is stored in a predetermined storage area of the RAM 30c. The number of operations is also cleared (“0” is set) when a big hit game is awarded.

  When the main CPU 30a determines the small hit, after the end of the symbol variation game based on the determined variation pattern, the main CPU 30a starts controlling the small hit game, and gives a predetermined control command to the overall control board 31 (the overall CPU 31a). Is output at a predetermined timing. Hereinafter, the control when the small hit game is awarded will be described in detail.

  When the symbol variation game ends, the main CPU 30a outputs a round command corresponding to the first round in order to start the first round game, and starts measuring the round game time (maximum 1300 (ms)). . In the present embodiment, the main CPU 30a opens the grand prize opening door 24 at most twice on condition that the upper limit number of game balls are not entered. The main CPU 30a that starts the first round game first outputs an opening signal as opening of the first grand prize winning door 24. Then, the main CPU 30a measures the time after opening the first prize opening door 24 (first opening), and when the opening time (600 (ms)) has elapsed, the first big prize opening door 24 is opened. A closing signal is output in order to end the opening of.

  Next, the main CPU 30a measures the time after closing the grand prize winning door 24 (first closing). At this time, the main CPU 30a measures the interval time (1000 (ms)) of the in-round interval set between the first opening and the second opening of the special winning opening door 24. Next, when the interval time has elapsed, the main CPU 30a outputs an opening signal as opening the second big prize opening door 24. Then, the main CPU 30a measures the time after the grand prize opening door 24 is opened (second opening), and when the opening time (600 (ms)) has elapsed, the second big prize opening door 24 is measured. A closing signal is output in order to end the opening of. Thereby, the round game in the small hit game is completed.

  Next, the main CPU 30a measures the time from the end of the round game. Then, the main CPU 30a outputs an ending command after the elapse of the final opening interval time (1000 (ms)) and starts measuring the ending time (2092 (ms)). Then, the main CPU 30a ends the small hit game after the ending time has elapsed. In the case of a small hit game, since the game state at the time of winning the small hit is maintained, the main CPU 30a maintains the current state of both the probability variation flag and the operation flag (does not set a new value).

  By executing the big hit game and the small hit game in this way, in the present embodiment, in the first and second 2R probability variable big hit games, 2R non-probable variable big hit games and small hit games, the opening mode of the big prize opening door 24 is opened. Are the same mode. That is, in the pachinko gaming machine 10 according to the present embodiment, even if the open state of the big prize opening door 24 is visually confirmed, which of the first and second 2R probability variable big hit games, 2R non-probability big hit games, and small hit games? I can't distinguish. From the above, when winning 1st, 2nd 2R probable big hit game, 2R non-probable big hit game or small hit game, the contents of the design variation game, the opening state of the big winning door 24, In principle, it is not possible to determine which winning game has been executed from the mode of giving the rate improvement state. Therefore, in such a state, it is possible to make the player expect that the probability variation state may be given, and the game can be continued.

  The main CPU 30a outputs a high-probability designation command and a short-time operation command when giving a probable change state and an increase in the entrance rate as the game state after the end of each big hit game. When assigning a state, a low probability designation command and a short time operation command are output. Further, the main CPU 30a outputs a high-probability designation command and a short-time non-operation command when only the probability variation state is set as the gaming state after the end of each big hit game. On the other hand, in the case of the small hit game, the game state at the time of the small hit game is maintained, so the main CPU 30a controls the game state at the time of the small hit game even during the small hit game, and after the small hit game ends, the game Does not output commands that specify status. The main CPU 30a outputs a short-time operation command after the end of the second 2R probability variable big hit game or 2R non-probable big hit, and 100 symbol variation games have passed without winning either big hit or small hit. In this case, a short time non-operation command is output to change the gaming state from the short time state to the normal gaming state. The main CPU 30a outputs a low probability command and a short time non-operation command when starting each big hit game, and is in a normal state during each big hit game.

  Further, when the main CPU 30a of the main control board 30 enters a game ball into the operation gate 25 and inputs a detection signal output by the gate sensor SW4 that detects the game ball, the main CPU 30a of the normal game stored in the RAM 30c. A general hold determination is made as to whether or not the reserved storage number is less than the upper limit number (4 in the present embodiment). When the determination result of the usual figure hold determination is affirmative (the number of ordinary figure hold memory <4), the main CPU 30a adds 1 (+1) to the number of reserved memories of the usual figure game and rewrites the number of reserved memories of the usual figure game. Further, when the main CPU 30a makes an affirmative determination of the normal symbol hold determination, the main CPU 30a acquires the value of the hit determination random number for the normal symbol from the RAM 30c, and displays the acquired value of the hit determination random number for the normal symbol. The information is stored in a predetermined storage area of the RAM 30c in association with the number of stored games stored. In addition, when the determination result of the general symbol hold determination is negative (the number of stored memories = 4), the main CPU 30a does not rewrite the general figure reserved memory number exceeding the upper limit number, and the random number for hit determination for the normal symbol Do not get value.

  Then, the main CPU 30a reads the value of the normal design hit determination random number stored in the predetermined storage area of the RAM 30c immediately before the start of the normal game, and the read value of the normal design hit determination random number and The normal symbol per unit determination value stored in the ROM 30b is compared to determine whether or not the normal symbol per unit. In the normal symbol hit determination, the main CPU 30a compares the low probability normal symbol hit determination value with the normal symbol hit determination random number value when the entry rate improvement state is not given as the gaming state, and the game When the entrance rate improvement state is given as the state, the determination value per normal symbol for high probability is compared with the value of a random number for hit determination for the normal symbol.

  When the determination result of the normal symbol hit determination is affirmative (the value of the hit determination random number matches the normal symbol hit determination value), the main CPU 30a determines the normal hit. The main CPU 30a, which has determined the normal winning, determines the winning symbol (ordinary symbol) to be confirmed and stopped in the normal symbol game performed on the normal symbol display H10. On the other hand, when the determination result of the normal symbol determination is negative (the value of the normal symbol determination random number and the normal symbol determination value do not match), the main CPU 30a normally determines a deviation. The main CPU 30a that has determined the normal deviation determines a normal deviation symbol (ordinary symbol) to be confirmed and stopped in the normal symbol game performed on the normal symbol display H10.

  And main CPU30a controls the display content of the normal symbol display H10 with the start of a usual game. That is, the main CPU 30a starts changing the normal symbol by starting the ordinary game, and displays the normal symbol (winning symbol or missing symbol) determined when a predetermined fluctuation time has elapsed in a fixed stop display. Note that the main CPU 30a sets a different variation time as the variation time of the usual game in accordance with the game state at the start of the ordinary game, and displays the normal symbol in a fixed stop state. Specifically, the main CPU 30a sets “10000 ms” as the variation time when the entrance rate improvement state is not given. When the entrance rate improvement state is given, “1100 ms”, which is a shorter time than when the entrance rate improvement state is not given, is set as the variation time. Thereby, the variation time of the normal symbol variation game performed when the entrance rate improvement state is given is shortened compared to the variation time of the symbol variation game performed in the non-short-time state.

  When determining the normal hit, the main CPU 30a executes the control related to the normal hit game after the normal game based on the determined normal fluctuation pattern. The main CPU 30a opens the open / close blade 22b three times when the normal game is finished, and when the entrance rate improvement state is given, and opens until 1600ms elapses after opening each time. The ordinary electric accessory solenoid SOL2 is controlled so as to maintain the state. On the other hand, the main CPU 30a opens the open / close blade 22b once and maintains the open state until 300 ms elapses after the normal game is finished, when the entrance rate improvement state is not given. Thus, the ordinary electric accessory solenoid SOL2 is controlled.

  Note that the main CPU 30a controls to close the opening / closing blade 22b when the upper limit number (for example, 10 balls) of game balls has entered even before the specified time has elapsed since the main CPU 30a opened. Similarly, even if the main CPU 30a has not been opened a predetermined number of times, when the upper limit number (for example, 10 balls) of game balls has entered, the main CPU 30a controls to close the opening / closing blade 22b.

  Next, various processes executed by the overall CPU 31a of the overall control board 31 based on the overall control program will be described. In the present embodiment, the overall CPU 31a of the overall control board 31 that executes the following various processes based on the overall control program includes an effect determination unit, a background switching lottery unit, a background determination unit, a count unit, a number determination unit, and a mode. It functions as production control means.

  When a predetermined control command is input from the main CPU 30a at a predetermined timing, the overall CPU 31a outputs a predetermined control command at a predetermined timing accordingly. More specifically, when the general CPU 31a inputs a variation pattern designation command, the overall CPU 31a outputs the variation pattern designation command to each of the control boards 32-34. Similarly, when the opening CPU, the round command, and the ending command are input, the overall CPU 31a outputs the opening command, the round command, and the ending command to the control boards 32 to 34, respectively. Further, the general CPU 31a sets the RAM 31c that the probability variation state is given when the high probability designation command is input, and sets the RAM 31c that the normal state (non-probability variation state) is given when the low probability designation command is inputted. . Further, the general CPU 31a sets in the RAM 31c that when the short-time operation command is input, the fact that the entering rate improvement state is given to the RAM 31c, and when the short-time non-operation command is inputted, it indicates to the RAM 31c that the entering rate improvement state is not given. Set. Then, the overall CPU 31a stores and maintains the current setting contents in the RAM 31c until a high probability designation command, a low probability designation command, a short time operation command, and a short time non-operation command are input. Further, when the general CPU 31a inputs these commands of a high probability designation command, a low probability designation command, a short time operation command, and a short time non-operation command, the general CPU 31a outputs each command to each of the control boards 32-34.

  Further, when the general CPU 31a inputs the variation pattern designation command and the special symbol designation command, the general CPU 31a displays the variable display H2 based on the variation pattern designated by the variation pattern designation command and the final stop symbol designated by the special symbol designation command. The symbol combination by the decorative symbol to be displayed is determined.

  More specifically, when the designated final stop symbol is a jackpot symbol corresponding to a 16R probability variable big hit game, the general CPU 31a can recognize that a 16R probability variable big hit game is given as a combination of decorative symbols. Determine the symbol combination. In the present embodiment, since the jackpot symbol combination is [111] [222] [333] [444] [555] [666] [777] [888] [999], the overall CPU 31a One of the jackpot symbol combinations is determined.

  In addition, when the designated final stop symbol is a big hit symbol corresponding to the first and second 2R probability variable big hit games and the 2R non-probable big hit game, the overall CPU 31a uses the symbol combination of the probability change suggestion as the decorative symbol combination. To decide. In addition, when the designated final stop symbol is a small hit symbol, the general CPU 31a selects a symbol combination indicating a probability variation as in the case of the first and second 2R probability variable big hit games or the 2R non-probable big hit game. decide.

  As described above, in this embodiment, in the case of the first and second 2R probability variation big hit games, 2R non-probability big hit games, or small hit games, only the symbol combinations that suggest the probability variation can be determined. Therefore, in the first and second 2R probability variable big hit games, 2R non-probability big hit games or small hit games, the mode of the big hit game or the small hit game is made the same mode, and the application mode of the improved entrance rate is the same mode In such a case, the player cannot recognize which of the big hit games or the small hit game is given not only from the game mode but also from the display content of the variable display H2.

  In addition, when the designated final stop symbol is an outlier symbol and a variation pattern for an outlier reach effect is designated, the overall CPU 31a determines a symbol combination for the outlier reach. In addition, when the designated final stop symbol is an outlier symbol and the variation pattern for the offending effect is designated, the overall CPU 31a determines the symbol combination of the off symbol.

  Then, the overall CPU 31 a outputs a decorative design designation command for designating the determined decorative design of each column to the display control board 32. In addition, when the overall CPU 31a inputs an all symbols stop command, the overall CPU 31a outputs the command to the display control board 32.

  In addition, when the jackpot game is awarded, the general CPU 31a determines an effect pattern that specifies the specific effect contents of the jackpot game, based on the combination of the designated final stop symbol and the jackpot symbol based on the determined decoration symbol, The effect pattern is output.

  More specifically, when the designated final stop symbol is a jackpot symbol corresponding to a 16R probability variable jackpot game, the general CPU 31a uses the game effect indicating that the 16R probability variable jackpot game is given as the effect content of the jackpot game. Output the pattern. In addition, the overall CPU 31a may be given a probability variation state when the designated final stop symbol is a jackpot symbol corresponding to the first and second 2R probability variation big hit games and 2R non-probability big hit games. The effect pattern which makes the game effect which suggests that the effect content of a big hit game is output. In addition, when the designated final stop symbol is a small hit symbol, the general CPU 31a applies a game effect having the same content as that of the first and second 2R probability variable big hit games or 2R non-probable variable big hit games to the small hit game. The production pattern which is the production content is output.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, when the first and second 2R probability variable big hit games, 2R non-probable big hit games or small hit games are awarded, the contents of the effects during these hit games are The player is prevented from recognizing whether or not a winning game has been awarded.

Next, the contents of control by the display control board 32 will be described.
When the sub CPU 32a of the display control board 32 inputs the variation pattern designation command output from the overall CPU 31a as the control related to the symbol variation game, the variable display H2 is configured to execute the symbol variation game designated by the variation pattern designation command. Controls the display content of. Further, when the sub CPU 32a inputs the all symbol stop command output from the overall CPU 31a, the variable display H2 displays the symbol combination of the ornament symbol designated by the ornament symbol designation command as the display result of the symbol variation game. Control display content.

  In addition, when the sub CPU 32a inputs an effect pattern and an opening command output from the overall CPU 31a as control related to the execution of the jackpot game, the sub CPU 32a is variable so as to execute the opening effect with the effect contents specified by the effect pattern and the opening command. The display content of the display H2 is controlled. Further, when the sub CPU 32a inputs the effect pattern and each round command, the sub CPU 32a controls the display content of the variable display H2 so that each round effect is executed with the effect pattern and the effect content specified by the round command. Further, when the sub CPU 32a inputs the effect pattern and the ending command, the sub CPU 32a controls the display content of the variable display H2 so that the ending effect is executed with the effect pattern specified by the effect pattern and the ending command.

  The lamp control board 33 controls the light emission mode of the decorative lamp 16 when an opening command, an ending command, and each round command are input. The voice control board 34 controls the voice output mode of the speaker 17 when an opening command, an ending command, and each round command are input. That is, the lamp control board 33 and the sound control board 34 perform control so as to perform an effect corresponding to the effect content instructed by these commands, like the display control board 32.

  As shown in FIGS. 8 and 9, the pachinko gaming machine 10 of the present embodiment provides a probability change notification mode effect (hereinafter referred to as “probability change mode”) for notifying the player that the game state is a probability change state. The variable display H2 which is a mode execution means is configured to be executable. In this embodiment, the mode execution means provides a probability change suggestion mode effect (hereinafter referred to as “probability change suggestion mode”) for notifying the player that the game state can be expected to be a probability change state. The variable display H2 can be executed. In the pachinko gaming machine 10 of the present embodiment, the chance mode effect (hereinafter referred to as “CH mode”), the first special mode effect (hereinafter referred to as “first special mode”), and the second special mode. There are four types of probability change suggestion modes that can be executed: an effect (hereinafter referred to as “second special mode”) and a third special mode effect (hereinafter referred to as “third special mode”).

  In addition, when neither the probability variation mode nor the probability variation suggestion mode, the normal mode effect (hereinafter, referred to as “the probability variation state that is executed when the gaming state is not the probability variation state” is high) "Normal mode") is configured to be executable by the variable display H2 which is the mode execution means. In the pachinko gaming machine 10 of the present embodiment, during the stay in the normal mode, the game state is actually a secret state that does not let the player know whether or not it is in the probability variation state, so the gaming state may be in the probability variation state. Since there is no absence, normal mode can also be defined as probability variation suggestion mode.

  In the present embodiment, the variable display H2 displays the decorative symbols in each column so as to overlap the background image, and the decorative symbol game is executed by variably displaying these decorative symbols. Yes. Then, in the pachinko gaming machine 10 of the present embodiment, the player is informed of the type of the presentation mode currently staying at the player from the type of the background image displayed on the variable display H2, and is in a certain change state. For example, it is informed whether the user can have an expectation, or informed that the state is in a probable state. The background image in the pachinko gaming machine 10 of the present embodiment is an image that can be configured excluding the symbols displayed in the symbol variation game, and is displayed in association with each decorative symbol that is variably displayed in the symbol variation game. Is different.

  As shown in FIG. 9, in the probability variation mode, after the 16R probability variation big hit game is finished, the probability variation state and the entrance rate improvement state are executed while the upper limit is given until the next big hit game is given. (Mode). In addition, the CH mode wins the first and second 2R probable big hit games and the 2R non-probable big hit game when the entrance rate improvement state is given, and the effect (mode that is executed after the big hit game ends) ). Note that in the CH mode, there are both lottery states of a probability variation state and a non-probability variation state. In addition, the first to third special modes and the normal mode are effects (modes) executed while the entrance rate improvement state is not given. Note that, in the first to third special modes and the normal mode, there are both lottery states of the probability variation state and the non-probability variation state.

  Next, transition modes of various modes as the game progresses will be described with reference to FIG. Note that details of the control of the overall CPU 31a during various modes will be described later. Further, FIG. 8 shows a mode transition mode when the entrance rate improvement state is not given inside the broken line portion, and mode transition when the entrance rate improvement state is given outside the dashed portion. An embodiment is shown.

  When the 16R probability variation big hit game is won, even if the player stays in any production mode (probability mode, CH mode, first to third special mode or normal mode), the mode changes to the probability variation mode. . That is, as in the case of 16R probability variable big hit game, if the winning rate is improved along with the probability changed state regardless of the game state at the time of winning, it will be given until the next big hit game is given (without "limit"). The variable display H2 is configured to execute the probability change mode so that the probability change notification state for notifying that the game state after the game ends is the probability change state. Note that the probability variation mode is provided when the next symbol variation game is started after the 16R probability variation big hit game ends.

  Further, when the small hit game is won while staying in the probability change mode, the game state at the time of winning is maintained, so the probability change mode is continued. In addition, when staying in the probability variation mode, when the first or second 2R probability variation big hit game or 2R non-probability big hit game is won, the mode is shifted to the CH mode. While staying in the probability variation mode to which the entrance rate improvement state is given, the time reduction state is always given after the end of the first and second 2R probability variation big hit games or 2R non-probability big hit games. For this reason, the gaming state is in a probabilistic state from the operation mode of the opening / closing blades 22b until at least 100 symbol variation games have elapsed after the end of the first and second 2R probable big hit games or the 2R non-probable big hit game. The player cannot recognize whether or not. That is, when the player cannot recognize whether or not the game state is a probable change state, such as the first and second 2R probable big hit games or the 2R non-probable big hit game, the game after the end of these big hit games The variable mode display H2 is configured to execute the CH mode so as to be in a probability variation concealment state informing that the state can be expected to be a probability variation state. It should be noted that the CH mode is given with the start of the next symbol variation game after the end of the first and second 2R probability variable big hit games or the 2R non-probable big hit game.

  In addition, the CH mode is continued when the first and second 2R big hit games, 2R non-probable big hit games or small hit games are won while staying in the CH mode. While staying in the CH mode with an improved entrance rate, the entrance rate is improved in any case after the 1st and 2nd 2R probable big hit games, 2R non-probable big hit game or small hit game ends. Is always granted continuously. For this reason, the player recognizes whether or not the gaming state is the probability variation state from the operation mode of the opening / closing blade 22b after the transition from the probability variation mode to the CH mode until at least 100 symbol variation games have elapsed. It is not possible. That is, if the player cannot recognize whether the gaming state is a probabilistic state, such as the first and second 2R probable big hit games, the 2R non-probable big hit game, or the small hit game, the probable concealment state is set. In order to continue, the CH mode is continuously executed by the variable display H2.

  Further, the CH mode is continued while the entrance rate improvement state is applied, and the entrance rate improvement state is not applied from the state where the entrance rate improvement state is applied. The game mode is shifted to the normal mode on the condition that the game state is shifted to the normal mode. For example, after the second 2R probability variation big hit game is over, if the winning of the small hit game in the 20th symbol variation game after shifting to the CH mode, with the end of the 80th symbol variation game from that win As soon as the application of the improved entrance rate is completed, the mode shifts to the normal mode. In addition, after the second 2R probability variable big hit game is finished, if the second 2R probability variable big hit game or 2R non-probable big hit game is won in the 20th symbol variation game after the transition to the CH mode, 100 from the winning With the completion of the second symbol variation game, the provision of the entrance rate improvement state is terminated and the mode is shifted to the normal mode. That is, the normal mode when the player still cannot recognize whether or not the game state is a probabilistic state so that the entrance rate improvement state is ended during the stay in the CH mode is the end of these jackpot games. It becomes a probability variation concealment state informing that it can be expected that the later game state is a probability variation state. It should be noted that the normal mode is given with the start of the next symbol variation game after the completion of the entrance rate improvement state.

  On the other hand, during the normal mode stay, the player recognizes whether or not the gaming state is in a probabilistic state, such as the first and second 2R probable big hit games, the 2R non-probable big hit game or the small hit game. If this is not possible, the variable display H2 is used to shift to one of the first to third special modes so that the probability-variation concealment state is established. In the normal mode where the entrance rate improvement state is not given, the entrance rate improvement state is not always given after the end of the first and second 2R probability variable big hit games, 2R non-probability big hit games or small hit games. It has become. For this reason, after the first and second 2R probability variation big hit games, 2R non-probability big hit games, or small hit games are over, the player recognizes whether or not the gaming state is the probability varying state from the operation mode of the opening / closing blade 22b. It is not possible. That is, if the player cannot recognize whether or not the gaming state is a probabilistic state, such as the first and second 2R probable big hit games, the 2R non-probable big hit game, or the small hit game, Thus, the first to third special modes are executed by the variable display H2. In addition, the 1st to 2nd 2R probability change in the first to third special modes triggered by winning of the first and second 2R probability variation big hit games, 2R non-probability big hit games or small hit games while staying in the normal mode. The game is given when the big hit game, the 2R non-probability big hit game, or the small hit game starts.

  In addition, during the stay in the first to third special modes, it is determined whether or not the gaming state is in the probable state, such as the first and second 2R probability variable big hit games, the 2R non-probable big hit games or the small hit games. When the person cannot recognize, the probability change suggestion mode during the stay is continued by the variable display H2 so that the probability variation concealment state is continued. While staying in the 1st to 3rd special mode where the entrance rate improvement state is not granted, the entrance rate improvement state after the end of the 1st, 2nd 2R probability variable big hit game, 2R non-probable big hit game or small hit game Is not granted. That is, if the player cannot recognize whether or not the gaming state is a probabilistic state after the end of the first and second 2R probable big hit games, the 2R non-probable big hit game or the small hit game, As a result, the special mode being executed is continued.

  In addition, the first to third special modes are continued until the mode end condition for each effect mode is satisfied, and the mode end condition for the effect mode during stay is not shown in FIG. The transition to the normal mode is made on the condition that it is established.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, the winning of the big hit or the small hit is the main trigger, and the execution is performed based on the type of the presentation mode during the stay, the type of the big hit or the small hit, and the gaming state assigned. The type of effect mode is determined. That is, when the variation pattern specified in the variation pattern designation command is a winning variation variation pattern, the general CPU 31a determines the final stop symbol and jackpot game designated in the special symbol designation command input together with the variation pattern designation command. The type of effect mode to be transferred is determined based on the game state after the end and the type of effect mode during the stay.

Next, a process executed by the overall CPU 31a while staying in each production mode will be described.
In the present embodiment, the general CPU 31a stores information (flags and the like) indicating the type of effect mode during stay in the RAM 31c, and can specify the type of effect mode during stay based on the information. The overall CPU 31a stores information (such as a flag) indicating the type of the determined effect mode in the RAM 31c after the end of each winning game or when determining the transition from the effect mode during the stay to another effect mode. It is like that. In addition, when the overall CPU 31a determines the transition from the effect mode during stay to another effect mode after the end of each winning game, the control CPU 31a sends an effect command that can specify the type of the determined effect mode to each control board 32 ~. 34. Then, the overall CPU 31a instructs the start of the effect mode determined by outputting an effect command that can specify the type of the determined effect mode, and starts the effect mode. In the pachinko gaming machine 10 of the present embodiment, the overall CPU 31a instructs the display control board 32 to enter the effect mode to be transferred by outputting an effect command. Then, the sub CPU 32a of the display control board 32 displays the type of background image determined from one or a plurality of types of background images corresponding to the effect mode shifted from the input effect command. Control display content. Specifically, when the effect mode to be transferred is the first to third special modes, the background image corresponding to the effect mode to be transferred is displayed on the variable display H2. When the effect mode to be shifted is the normal mode, a predetermined type of background image is displayed on the variable display H2 among the background images dedicated to the normal mode.

  In addition, in the control during the stay in each effect mode, the overall CPU 31a controls each control at a predetermined timing for an effect command that can individually specify the contents for instructing the execution of various effects and the contents of various decisions as a result of processing related to various effects. It outputs to the board | substrates 32-34. Further, the general CPU 31a sets (stores) the contents instructed by the command in the RAM 31c each time when the production command is output. Then, the general CPU 31a can freely read out and confirm (confirm) the contents instructed to each of the control boards 32 to 34 and the effects of various game effects executed on the variable display H2 or the like from the RAM 31c. ing.

Here, the process during the normal mode stay will be described.
When the general CPU 31a instructs the start of the normal mode, the general CPU 31a continues the normal mode until the transition to another effect mode. Then, the overall CPU 31a determines the transition from the normal mode to the probability variation mode after the 16R probability variation big hit game ends. In addition, the general CPU 31a makes a transition from the normal mode to any one of the first to third special modes when the first and second 2R probability variable big hit games, 2R non-probable big hit games or small hit games start. A time transfer lottery is performed. In other words, the general CPU 31a receives a variation pattern designation command for designating the variation pattern P6 while staying in the normal mode, and uses the special symbol designation command for the first and second 2R probability variable big hit games, 2R non-probable big hit games or small hits. As the game is specified, the normal mode transition lottery is performed, and the execution of the effect mode to be transitioned is instructed based on the result of the normal mode transition lottery.

  In the normal mode transition lottery, the general CPU 31a specifies that the first and second 2R probability variable big hit games are designated rather than the case where the 2R non-probable big hit game or the small hit game is designated by the special symbol designation command. It is easy to determine the transition to the first special mode. For this reason, during the stay in the normal mode, out of the probability variation suggestion modes in which the production mode can be shifted, there is an expectation for the probability variation state when shifting to the first special mode rather than when shifting to the second and third special modes. It is getting higher. Further, in the pachinko gaming machine 10 of the present embodiment, the transition to the first special mode that can be shifted only by the first and second 2R probability variable big hit games, 2R non-probable big hit games and small hit games is the second and second The expectation of the probability change state is higher than the transition to the 3 special mode.

  The pachinko gaming machine 10 according to the present embodiment is configured to be able to display a plurality of types of background images on the variable display H2 during the stay in the normal mode. The background images for the normal mode are “castle background” with “castle” as the motif, “mountain background” with “mountain” as the motif, “town background” with “townscape” as the motif, and “house” There are four types of “house background” with the motif. Further, the background image of the variable display H2 during the stay in the normal mode can be changed to a different background image. That is, in the pachinko gaming machine 10 according to the present embodiment, in accordance with the input of the variation pattern designation command, the background image is switched based on the designated variation pattern type and the current background image type (change). There is a case.

  Further, in the pachinko gaming machine 10 of the present embodiment, not only the background image is changed during the normal mode, but also the background image displayed in the second and third special modes can be determined by lottery at the same time. . That is, in the present embodiment, during the stay in the normal mode, by changing the background image to another background image for the normal mode, the background image is changed to the second and third special mode background images. It appears to have shifted to the 3 special mode. In addition, when the background image is changed during the stay in the normal mode, when changing to the background image dedicated to the normal mode and when changing to the second and third special modes (background images), the same effects are passed. Change. For this reason, in the pachinko gaming machine 10 of the present embodiment, during the stay in the normal mode, the background image may be switched with the start of the symbol variation game, and further, the background image may be switched with the end of the symbol variation game. .

  And in the pachinko gaming machine 10 of this embodiment, as shown in FIG. 10, according to the type of the current background image, the type of the background image to be switched is determined in advance. For example, as shown in FIG. 10, when the current background image is “castle background” while staying in the normal mode, “mountain background”, “town background”, “house background”, “background image of the second special mode” (Hereinafter simply referred to as the second special mode) and “background image of the third special mode (hereinafter simply referred to as the third special mode)”. A background image other than the current background image can be selected.

  Further, the overall CPU 31a decides to shift to the normal mode, and at the time of granting the normal mode, first, the minimum number of changes (minimum number of executions) as the minimum number of times and the maximum number of changes (maximum number of executions) as the maximum number of times. To decide. The minimum variation count is the number of times that the symbol variation game with the same type of background image can be continued on the condition that the regular mode stays (is) during the regular mode stay. In the pachinko gaming machine 10 of the present embodiment, even when the number of symbol variation games with the same type of background image is less than the minimum variation number, a symbol variation game with a high jackpot expectation is executed or In the case of mode transition when a small hit game or the like is given, the background image is switched. The maximum variation number is the upper limit number of variations (execution count) of the symbol variation game by the same type of background image, and in this embodiment, the variation count (execution count) of the symbol variation game by the same type of background image. However, when the maximum number of fluctuations is reached, another type of background image can be forcibly switched.

  In the present embodiment, the overall CPU 31a, when the normal mode is started or when the background image is switched, the number of changes in the symbol variation game executed by the symbol variation game based on the background image at the start without switching the background image ( The number of executions) is stored in the RAM 31c. Whenever the central CPU 31a executes the symbol variation game of the same type of background image, the execution count of the RAM 31c is incremented by 1 (+1) and updated to switch to another background image or to shift to another effect mode. As a result, the number of fluctuations of the RAM 31c is cleared (reset to 0 (zero)).

  In the present embodiment, as shown in FIG. 11, the period T <b> 1 is a period until the number of fluctuations of the RAM 31 c reaches the maximum number of fluctuations during the stay in the normal mode. Further, the period T1 is divided into a period T2 until reaching the minimum number of fluctuations and a period T3 until reaching the maximum number of fluctuations after reaching the minimum number of fluctuations.

  In the symbol variation game in which the number of executions reaches the maximum number of variations, the overall CPU 31a refers to the forced switching lottery table shown in FIG. 12 to forcibly switch the background image if the background image can be switched. I have to. Specifically, when the current background image is “mountain”, the overall CPU 31a determines to switch the background image to “castle” with a probability of 50/150. Further, the overall CPU 31a determines to switch the background image to “town” with a probability of 50/150, and determines to use the background image as a mansion with a probability of 50/150. In the present embodiment, as shown in FIG. 12, the current background image type (eg, “mountain”) is not determined as the type of background image to be switched.

  In the present embodiment, in the period T1 shown in FIG. 11, as shown in FIG. 10, a lottery for switching whether or not to switch to a different type of background image from the current background image type is performed. The general CPU 31a acquires a random number, performs lottery switching by random number lottery as to whether or not the acquired random number value matches a predetermined winning value, and changes the background image from the current background image type to another type. To switch to the background image. Specifically, the overall CPU 31a can switch the background image when the acquired random number value matches the winning value.

  Further, in the present embodiment, as shown in FIG. 11, a period T2 until the number of changes in the RAM 31c reaches the minimum number of changes, and a period until the number of changes in the RAM 31c reaches the maximum number of changes after reaching the minimum number of changes. Whether or not the background image is actually switched is different from T3 regardless of whether or not the switching lottery is won.

  In the period T2, it is determined whether or not the background image is switched, that is, whether or not switching is possible, depending on the type of the variation pattern designated by the variation pattern designation command from the main CPU 30a. Specifically, when the variation pattern specified by the input variation pattern designation command is a specific variation pattern, the overall CPU 31a causes the background image to be switched in response to winning of the switching lottery. A background specifying command instructing this is output to the display control board 32. On the other hand, the overall CPU 31a does not output the background specifying command when the changing pattern specified by the input changing pattern specifying command is not a specific changing pattern.

  If the switching CPU lottery is won when a specific variation pattern is not designated, the overall CPU 31a stores history information indicating that the switching lottery has been won in the RAM 31c. The overall CPU 31a stores history information, and reserves switching of the background image until the number of changes reaches the minimum number of changes. For this reason, the overall CPU 31a reserves switching of the background image after the fluctuation count reaches the minimum fluctuation count by storing the history information. In the present embodiment, when history information is stored when the number of changes reaches the minimum number of changes, the background image is switched without performing the switching lottery. Reservation means storing (reserving) in advance that switching is performed when the minimum number of changes is reached by storing in advance that the switching lottery has been won.

  Here, the specific variation pattern refers to a variation pattern including production contents with high expectation degree of jackpot. In the present embodiment, since the super reach variation is likely to be executed when the big hit, the variation patterns P3 and P5 for performing the super reach variation are set as specific variation patterns (specific variation patterns). That is, in the period T2, when the variation patterns P3 and P5 are determined, the background image may be switched to a type different from the current background image type.

  On the other hand, in the period T3, regardless of the type of variation pattern designated by the inputted variation pattern designation command, when switching to a background image of a different type from the current background image type when triggered by the switching lottery There is. In addition, the overall CPU 31a may switch the background image when the number of changes reaches the minimum number of changes while the history information is stored in the RAM 31c.

  However, in the pachinko gaming machine 10 of the present embodiment, the background image may not be switched depending on the contents of the effect even if the switching lottery is won or the history information is stored in the RAM 31c. Specifically, the variation pattern not shown in FIG. 5 includes a variation pattern that includes an effect that the background image cannot be switched, and that the background image cannot be switched. When the variation pattern that disables the switching of the background image is designated by the variation pattern designation command, the overall CPU 31a may not perform the switching lottery and does not perform the switching of the background image. That is, even in the case of a symbol variation game in which the number of variations of the RAM 31c has reached the maximum number of variations, when the variation pattern that disables the switching of the background image is designated by the variation pattern designation command, the background image is forcibly changed. There is no switching.

  When it is determined that the background image is to be switched, that is, when the background image can be switched, the overall CPU 31a selects and determines the background image to be switched from the background images shown in FIG. Specifically, random numbers are assigned to different types of background images from the current background image, and the type of background image to be switched is determined by random number lottery. Since the current background image type is not selected, random numbers are not assigned to the current background image as shown in FIG. Then, the overall CPU 31a that has determined the type of the background image to be switched outputs a background specifying command that can specify the type of the background image to be switched to the display control board 32. In the present embodiment, when the variation pattern P6 is designated by the variation pattern designation command, the background image of the effect mode that can be specified from the effect command is specified. On the other hand, when the variation patterns P1 to P5 are designated by the variation pattern designation command, the type of the background image to be switched can be identified by the background identification command.

  The general CPU 31a is configured to execute a notice effect when switching the background image. The overall CPU 31a also determines the type of effect content of the notice effect. The notice effect is executed when the display screen of the variable display H2 appears so as to cover the display screen of the variable display H2 prior to the switching of the background image. In the present embodiment, the color of “襖” appearing in the notice effect (in this embodiment, “white” and “gold”) is used to indicate to the player the degree of expectation for the big hit of the symbol variation game. ing. Then, when the specific variation pattern (variation patterns P3 and P5) for performing the super reach variation is determined as the determined variation pattern, the overall CPU 31a has “white” <“gold” as the effect content of the notice effect. It becomes easier to determine in order. On the other hand, when the determined variation pattern is a variation pattern that does not perform the super reach variation, it is easy to determine “gold” <“white” in the order of the effect of the notice effect. In other words, the color “gold” of “襖” is easy to be executed as a notice effect of a symbol variation game in which a super-reach variation is performed with a high degree of big hit expectation. Further, in the present embodiment, when a specific variation pattern is determined in the period T2 in FIG. 11, the background image switching trigger is set. For this reason, in the period T2, when the background image is inevitably switched, a notice effect with the color “襖” being “gold” is likely to be executed.

  When the overall CPU 31a determines to execute the switching of the background image, the general CPU 31a determines the content of the notice effect (the color of “襖”). Specifically, based on the variation pattern designated by the variation pattern designation command from the main CPU 30a, the content of the effect of the notice effect is determined with reference to the notice effect distribution table shown in FIG. For example, when the variation pattern designated by the variation pattern designation command is the variation pattern P5, the overall CPU 31a determines that the color “襖” is set to “white” with a probability of 26/251. On the other hand, the overall CPU 31a determines that the color of “襖” is “gold” with a probability of 225/251.

  Then, the general CPU 31a that determines the content of the effect of the notice effect, that is, the color of “襖” instructs the execution of the notice effect and displays a notice command that can specify the color of “襖” in the notice effect. 32.

  Further, the overall CPU 31a determines the minimum number of times of change and the maximum number of times of change after outputting various commands related to the switching of the background image. Here, how to determine the minimum number of fluctuations and the maximum number of fluctuations will be described with reference to FIG.

  As shown in FIG. 14, the overall CPU 31a predetermines the reference number (in this embodiment, “15”) when determining the minimum number of changes. In addition, the number of additions (in this embodiment, “0 times” to “10 times”) determined by random number lottery using random numbers is added as the minimum number of fluctuations to the reference number of the minimum number of fluctuations. In determining the number of additions, a predetermined number of random numbers are assigned to each of “0” to “10”, and the overall CPU 31a determines the number of additions from “0” to “10”. It is supposed to be. For this reason, in the pachinko gaming machine 10 of the present embodiment, the minimum variation number is set to “15 times” obtained by adding “0” to the reference number to be the minimum minimum variation number. On the other hand, “25 times” obtained by adding “10 times” to the reference number of times is set as the maximum of the minimum number of fluctuations. That is, the overall CPU 31a determines the minimum number of fluctuations in the range of “15 times” to “25 times”.

  Further, as shown in FIG. 14, the overall CPU 31a predetermines the reference number (in this embodiment, “40 times”) when determining the maximum number of fluctuations. Also, the number of subtractions (in this embodiment, “0” to “10”) determined by random number random lottery with the random number is determined as the maximum number of fluctuations. In determining the number of subtractions, a predetermined number of random numbers are assigned to each of “0” to “10”, and the overall CPU 31a determines the number of subtractions from “0” to “10”. It is supposed to be. For this reason, in the pachinko gaming machine 10 according to the present embodiment, the maximum variation number is set to “40 times” obtained by subtracting “0” from the reference number as the maximum maximum variation number. On the other hand, “30 times” obtained by subtracting “10 times” from the reference number is set as the minimum of the maximum number of fluctuations. That is, the overall CPU 31a determines the maximum number of fluctuations in the range of “30 times” to “40 times”.

  In the pachinko gaming machine 10 of the present embodiment, the reference number for the minimum number of fluctuations is “15”, and the reference number for the maximum number of fluctuations is “40”. In this embodiment, the number of additions and the number of subtractions are set to “0” to “10”, and are smaller than the difference “25” of the reference number of each variation number. Even if the maximum number of additions (in this embodiment, “10 times”) is added to the reference number corresponding to the minimum fluctuation number, the maximum number of subtractions (in this embodiment) from the reference number corresponding to the maximum fluctuation number. , “10 times”) is less than the number of subtractions. In other words, “25 times” obtained by adding the maximum number of additions “10 times” to the reference number of times of minimum fluctuations is more than “30 times” obtained by subtracting the maximum number of times of subtraction “10 times” from the reference number of times of maximum fluctuations. It is getting smaller. Even when any number is determined as the number of additions and the number of subtractions, the minimum variation number is smaller than the maximum variation number (minimum variation number <maximum variation number).

  In the pachinko gaming machine 10 according to the present embodiment, the minimum variation number and the maximum variation number are randomly determined each time the background image is switched by adopting a configuration in which the minimum variation number and the maximum variation number are determined by random number lottery. It has come to be able to do. The overall CPU 31a that has determined the minimum fluctuation count and the maximum fluctuation count stores the determined minimum fluctuation count and maximum fluctuation count in the RAM 31c until the background image is switched. In addition, when the background image is switched and the overall CPU 31a newly determines the minimum variation count and the maximum variation count, the minimum variation count and the maximum variation count stored in the RAM 31c are rewritten.

  When the processing of the overall CPU 31a for switching the background image is completed, the processing for background image switching of the display control board 32 to which various commands output from the overall CPU 31a are input is executed.

  The sub CPU 32a of the display control board 32 recognizes that the background image is switched when the background specifying command output from the overall CPU 31a is input. Then, the sub CPU 32a specifies the contents of the effect of the notice effect that is executed when the background image is switched from the notice command output by the general CPU 31a. Then, during the symbol variation game, the variable display H2 is controlled so that the notice effect is executed at a timing before the background image set for each variation pattern is switched. Then, the sub CPU 32a specifies the type of background image to be displayed after the end of the notice effect from the background specifying command output by the overall CPU 31a. Then, after causing the variable display H2 to execute the notice effect, the display content of the variable display H2 is controlled so that the type of background image specified by the background specifying command is displayed. In the present embodiment, the background image of the second and third special modes instructing display when the second and third special modes are set by the effect command, and the second instructing to display by the background specifying command are provided. 2. The background image data in the third special mode is the same. Therefore, the background image displayed on the variable display H2 is also the same, and the special mode (for example, the third special image) is not passed from the background image in the normal mode (for example, “house”) without winning such as a small hit. When the mode image is switched to the background image, it is possible to make the player think that the probability variation state may have been given. In the present embodiment, the overall CPU 31a and the sub CPU 32a function as a notice effect execution unit. In the present embodiment, the sub CPU 32a functions as background control means.

Here, the background switching process executed by the overall CPU 31a will be described in detail. The overall CPU 31a executes the background switching process shown in FIG. 15 at the start of the symbol variation game.
First, the overall CPU 31a adds “1” to the number of changes stored in the RAM 31c at the start of the symbol change game (step S41). Further, the overall CPU 31a that adds “1” to the number of changes in the RAM 31c identifies the type of the change pattern specified by the input change pattern specifying command (step S42). The overall CPU 31a compares the number of fluctuations stored in the RAM 31c with the minimum number of fluctuations stored in the RAM 31c, and determines whether or not the number of fluctuations has reached the minimum number of fluctuations. It is determined whether the number is less than the number of times (step S43). If the determination result in step S43 is affirmative, that is, if the number of changes is less than the minimum number of changes, the overall CPU 31a determines whether or not the type of the change pattern specified in step S42 is a specific change pattern. (Step S44). In step S44 in this embodiment, it is determined whether or not the variation pattern designated by the variation pattern designation command is the variation pattern P3 or P5 for performing the super reach variation. If the determination result in step S44 is negative, that is, if a variation pattern other than a specific variation pattern is specified, the overall CPU 31a acquires a random number (step S45). Further, the overall CPU 31a determines whether or not the value of the random number acquired in step S45 matches a predetermined winning value, that is, whether or not the switching lottery has been won (step S46). If the determination result in step S46 is affirmative, that is, if the selection lottery in step S46 is won, the history information is stored in the RAM 31c (step S47). Then, the overall CPU 31a ends the background switching process. If the determination result in step S46 is negative, that is, if the switching lottery in step S46 is not won, the overall CPU 31a ends the background switching process.

  If the determination result in step S44 is affirmative, that is, if the type of variation pattern specified in step S42 is a specific variation pattern, the overall CPU 31a acquires a random number (step S48). In addition, the overall CPU 31a determines whether or not the random number value acquired in step S48 matches a predetermined winning value, that is, whether or not the switching lottery has been won (step S49). If the determination result in step S49 is affirmative, that is, if the switching lottery in step S49 is won, the overall CPU 31a determines the type of background image to be switched (step S50). Further, the overall CPU 31a that has determined the type of background image to be switched determines the color of “に お け る” in the notice effect by referring to the notice effect distribution table shown in FIG. 13 according to the type of the variation pattern specified in step S42. (Step S51). Further, the overall CPU 31a that has determined the type of background image to be switched and the color of “襖” in the notice effect, the background specifying command corresponding to the decided type of background image, and the notice command corresponding to the decided “襖” color. Is output to the display control board 32 (step S52). Then, the overall CPU 31a ends the background switching process. If the determination result of step S49 is negative, that is, if the switching lottery of step S49 is not won, the overall CPU 31a ends the background switching process.

  If the determination result in step S43 is negative, that is, if the number of changes stored in the RAM 31c is equal to or greater than the minimum number of changes, the overall CPU 31a disables switching of the background image with the change pattern specified in step S42. It is determined whether or not the pattern is a variation pattern (step S53). If the determination result in step S53 is affirmative, that is, if the variation pattern specified in step S42 is not a variation pattern that disables switching of the background image, the overall CPU 31a determines whether history information is stored in the RAM 31c. Is determined (step S54). If the determination result of step S54 is affirmative, that is, if history information is stored in the RAM 31c, the overall CPU 31a proceeds to the process of step S50.

  On the other hand, if the determination result in step S54 is negative, that is, if history information is not stored in the RAM 31c, the general CPU 31a determines whether the number of changes stored in the RAM 31c is greater than or equal to the maximum number of changes stored in the RAM 31c. It is determined whether or not (step S55). If the determination result in step S55 is affirmative, that is, if the number of changes stored in the RAM 31c is greater than or equal to the maximum number of changes, the overall CPU 31a proceeds to the process in step S50. On the other hand, if the determination result of step S55 is negative, that is, if the number of changes stored in the RAM 31c is less than the maximum number of changes, the overall CPU 31a acquires a random number (step S56). In addition, the overall CPU 31a determines whether or not the random number value acquired in step S56 matches a predetermined winning value, that is, whether or not the switching lottery has been won (step S57). If the determination result of step S57 is affirmative, that is, if the selection lottery of step S57 is won, the overall CPU 31a proceeds to the process of step S50. On the other hand, if the determination result of step S57 is negative, that is, if the switching lottery of step S57 is not won, the overall CPU 31a ends the background switching process. If the determination result in step S53 is negative, that is, if the variation pattern specified in step S42 is a variation pattern that disables switching of the background image, the overall CPU 31a ends the background switching process.

As described above in detail, the present embodiment has the following effects.
(1) In a symbol variation game in which the number of variations reaches the minimum variation number, in a symbol variation game with a low jackpot expectation level, the symbol variation is high (based on variation patterns P3 and P5) without switching the background image. The background image was switched in the game. By doing so, it becomes easy to execute the switching of the background image in the symbol variation game with a high expectation degree of jackpot. When the background image is switched in a symbol variation game with a high degree of expectation for jackpot, a notice effect with a high degree of expectation for jackpot where the color of “襖” is “gold” is executed with a high probability.

  That is, by providing the minimum number of fluctuations, the background image is prevented from frequently switching, and when the symbol variation game with a high jackpot expectation is executed when the number of fluctuations has not reached the minimum number of fluctuations, Switch images. At the same time, it is possible to positively execute a notice effect of “gold” with the color of “襖” having a high expectation degree of jackpot. For this reason, it is possible to improve the player's interest by increasing the possibility that a notice effect with a high jackpot expectation in which the color of “襖” is “gold” will be executed.

  (2) By setting the maximum number of fluctuations, the background image is forcibly switched when the background image does not switch easily (when the switching lottery is not won) after the number of fluctuations reaches the minimum number of fluctuations. . By doing in this way, it can prevent that the design change game in the same kind of background image continues all the time. Accordingly, it is possible to prevent the player from getting bored due to the continued symbol variation game using the same background image.

  (3) Until the number of fluctuations reaches the minimum number of fluctuations (period), the switching lottery is performed even if a specific fluctuation pattern is not determined (fluctuation patterns P3 and P5). Then, when winning the switching lottery during the period, the fact that it has been won is stored and held. In the symbol variation game in which the number of variations reaches the minimum number of variations, when the winning is stored and held, the background image is determined and the background image is switched. By doing so, it is possible to reserve the switching of the background image when winning the switching lottery in the symbol variation game executed until the variation number reaches the minimum variation number. That is, since the switching lottery is performed from the first variation count, the chance to win the switching lottery increases, and the background image is easily switched after the minimum variation count. As a result, the background image is easily switched at the number of times the designer intends to switch the background image.

  (4) The background image displayed during the second and third special modes is displayed even during the normal mode. In this way, even when the normal mode is set, the player can expect a promising state by switching the background image to the background image displayed during the second and third special modes. It can be made as if the second and third special modes were set. Further, by switching from the background image in the normal mode to the background image in the second and third special modes, the player can be made to think that it has become a probable change state and is likely to be a big hit. As a result, the player can expect that the symbol variation game may be a big hit, and the game can be continued.

  (5) By sequentially changing the minimum number of fluctuations, the minimum number of fluctuations can be varied. In other words, the player cannot recognize how many times the design variation game with the same type of background image continues. By doing so, it is impossible to know the trigger for switching the background image. That is, the player cannot recognize whether the background image has been switched because the minimum number of variations has been reached, or whether the background image has been switched because the jackpot expectation of the symbol variation game is high. Therefore, it is possible to have a sense of expectation in the symbol variation game in which the background image is switched.

  (6) By sequentially changing the maximum number of fluctuations, the maximum number of fluctuations can be varied. Also, the player cannot recognize how many times the symbol variation game with the same type of background image will continue. By doing so, it is impossible to know the trigger for switching the background image. For this reason, it is possible to play a game with a sense of expectation that it is not simply a background image switching due to the maximum number of fluctuations being reached.

  (7) In the symbol variation game with less than the minimum variation number (15 times), when the background image is switched, it is determined that the super reach variation is performed. That is, the big hit expectation degree of the symbol variation game in which the background image has been switched less than the minimum number of changes is high, and the player expects that the background image will be changed before reaching the minimum number of changes. It can be carried out.

In addition, you may change the said embodiment as follows.
In the above embodiment, the specified number of rounds of the round game, the time required for one opening / closing operation of the special prize opening device 23, and the round game time may be changed.

-Although the said embodiment was actualized in the pachinko gaming machine 10 using a special symbol and a decoration symbol, you may materialize in the pachinko gaming machine using only a special symbol.
In the above embodiment, the overall control board 31 is omitted, and commands related to jackpot games such as an open command and a close command are directly sent from the main control board 30 to the display control board 32, the lamp control board 33, and the voice control board 34. You may make it output.

  In the above embodiment, the type of jackpot game may be arbitrarily changed. For example, the specified number of rounds of the big hit game and the upper limit number of entering balls may be changed. Further, the number of opening / closing operations of the special prize opening device 23 may be changed. For example, the special winning opening device 23 may be opened and closed three times during one round game.

  In the above embodiment, the variable display H2 is a liquid crystal display, but it may be a dot matrix display, a 7 segment LED display, or a mechanical display such as a drum display.

  The maximum number of fluctuations in the above embodiment may be a predetermined constant. The maximum number of fluctuations may be determined by random number lottery using random numbers from “30 times” to “40 times”, for example. Further, the reference number corresponding to the maximum variation number may be changed, and the upper and lower limits of the decrease number may be changed. In determining the maximum number of fluctuations, the ratio for determining the number of reductions may be equalized or may be biased.

  The minimum number of fluctuations in the above embodiment may be a predetermined constant. Further, the minimum number of fluctuations may be determined by random number lottery using random numbers from “15 times” to “25 times”, for example. Further, the reference number corresponding to the minimum variation number may be changed, and the upper and lower limits of the addition number may be changed. In determining the minimum number of fluctuations, the ratio for determining the number of additions may be equalized or may be biased.

  In the above embodiment, when switching the background image by switching lottery while staying in the normal mode, the background image for normal mode (“castle background”, “mountain background”, “town background” is selected as the type of background image to be switched. Or “house background”). In other words, the normal mode may not be shifted to another production mode without passing through a winning game.

  In the above embodiment, when the background image of the second and third special mode is determined as the background image for the normal mode, the overall CPU 31a outputs the effect command, and the effect mode is the second and third special mode. You may be able to recognize that there is.

  In the above embodiment, whether or not the background image can be switched and the type of the background image to be switched are determined by individual lottery, but it is not necessary to do so. For example, you may make it determine simultaneously.

  In the above embodiment, the variation pattern that disables the switching of the background image is provided. For example, the background image may always be switched when the maximum number of fluctuations is reached.

  -In the above embodiment, when the number of fluctuations has not reached the minimum number of fluctuations, even if a specific fluctuation pattern has not been determined, switching lottery is performed, and history information is stored when winning, You don't have to. For example, when the number of changes does not reach the minimum number of changes, the switching lottery may not be performed.

  In the above embodiment, the winning probability of the switching lottery is not related to the type of variation pattern, but may be related. By changing the winning probability of the switching lottery for each variation pattern, depending on the setting method, it becomes easier to switch the background image in a symbol variation game with a high jackpot expectation level, and the background image is switched in a symbol variation game with a low jackpot expectation level It can be difficult. In this case, the background image can be easily switched in the symbol variation game with a higher expectation level for jackpots, and a notice effect with a higher expectation level for jackpots can be easily performed.

  -In the said embodiment, what is necessary is just the structure which can be concealed to a player whether a game state is a probable state, for example, change the number of times of giving in the case of grant of the entrance rate improvement state, or granting arbitrarily You can also In addition, for example, a pachinko gaming machine in which only a jackpot game where a player with an upper limit of 16 is able to obtain many prize balls is provided, and either a probabilistic state or a non-probable state is given after the jackpot game ends. You may apply to. In addition, for example, a 16R probability variation jackpot game based on the symbol A (a jackpot game where the player can acquire many prize balls) and a second 2R probability variation jackpot game based on the symbol C (the player can hardly obtain the prize balls). And 2R non-probable big hit game based on the design D (a big hit game in which the player cannot almost win a prize ball). In other words, the probability variation state can be concealed by the symbols C and D even if a small hit game is not provided. In addition, for example, as a winning game, a 16R probability variable big hit game based on the symbol A, a 2R probability variable big hit game based on either the symbol B or the symbol C, and a non-probable change state after the end of the 16R big hit game in addition to the small hit game It is sufficient to provide at least a 16R non-probability big hit game that grants. In other words, even if the 2R non-probability big hit game is not provided, the probability change state can be concealed by any 2R probability big hit game and small hit game based on the symbol B or the symbol C.

  In the above embodiment, the player is allowed to acquire a prize ball by extending the opening time of the big prize opening device 23 in the first and second 2R probability variable big hit games and 2R non-probable big hit games. You can also.

  In the above embodiment, the main CPU 30a may acquire all the random numbers related to the determination of the symbol variation game from the RAM 30c when the start winning devices 21 and 22 are awarded. The main CPU 30a may output a command that can specify the value of the random number to the general CPU 31a in the random number used by the general CPU 31a.

  In the above embodiment, when history information is stored, the background image is changed after reaching the minimum number of changes, but even if the minimum number of changes is not reached, a specific change pattern When is selected, the background image may be switched.

-In the said embodiment, it is not necessary to provide the maximum frequency | count of fluctuation.
-In the said embodiment, it is not necessary to provide all the production modes. For example, the effect mode may be only the normal mode.

  In the above embodiment, the timing of executing the notice effect may be any time during the symbol variation game. The timing for switching the background image may be any time as long as it is during the symbol variation game. Further, it is not necessary to execute the notice effect at the timing before the background image is switched.

  In the above embodiment, the transition of the effect mode may be performed at any time during the symbol variation game. For example, the symbol variation game may be started, or five seconds after the symbol variation game starts, or the symbol variation game may be ended.
