Description

  The present invention relates to a gaming machine in which a symbol variation game performed by varying a plurality of types of symbols is performed on a display device, and a jackpot game is awarded when the symbol variation game results in a jackpot display result.

  Conventionally, pachinko gaming machines, which are a type of gaming machine, include, for example, a liquid crystal display type display device, and when the game ball wins a winning winning opening, the display device changes a plurality of types of symbols. The game is taking place. In such a pachinko gaming machine, in addition to the reach effect, a notice effect is provided to notify (notify) the player that the game will be a big hit in the symbol variation game (for example, Patent Document 1). In Patent Document 1, a notice effect is determined separately from the reach effect specified by the change pattern based on the change pattern. And in patent document 1, when a notice pattern with a high degree of jackpot expectation appears by adopting a configuration in which a notice effect with a high degree of jackpot expectation is easily selected when a variation pattern with a high degree of expectation of jackpot is selected. It is designed to increase the player's expectation for jackpot.

JP 2007-044198 A (paragraph number [0134])

  By the way, a pachinko machine having a probability variation (probability variation) function is known. The probability variation function is a probability that the jackpot lottery probability will change from a normal probability with a low probability to a high probability after the jackpot game ends, provided that the jackpot combination is a combination with a predetermined probability variation (specific symbol) This is a function to give a fluctuation state. If the probability variation state is given, the lottery probability of the big hit fluctuates with a high probability and the big hit is likely to occur. It is even more advantageous for the player, and the player is playing the game with the expectation that it will be a big hit.

  And in a pachinko machine equipped with a probability change function, the probability of winning a big hit is very high during the probability change state and the possibility of winning the next big hit is very high. Wants to win a promising big hit. Therefore, the player desires to be a big hit when the reach state is formed with a symbol that suggests a probable big hit, while the player desires to lose when the reach state is formed with a symbol that suggests a non-probable big hit.

  However, in the gaming machine described in Patent Document 1, the notice effect is determined based only on the variation pattern. For this reason, if it is set so that a common big hit effect variation pattern is selected regardless of which jackpot is won, the type of the notice effect cannot be varied depending on whether or not the winning jackpot has been won. Therefore, even if a reach state is formed with a symbol that suggests a probable big hit, there is a possibility that a notice effect with a low big hit expectation level is selected. In such a case, the player expects a promising big hit by visually recognizing the combination of symbols that have formed the reach state. As a result, there is a possibility that the player's willingness to be lost and the player's willingness to play may decrease. To put it the other way around, when a reach state is formed with a design that suggests a non-probable big hit, it is highly likely that the probable state will end if a notice effect with a high expectation level is executed. In other words, the player's willingness to play may be reduced.

  The present invention has been made in view of such circumstances, and its purpose is to determine the content of the notice effect in consideration of the type of reach formation symbol, and when the reach is formed by a specific symbol The object is to provide a gaming machine that can be expected to be given a promising state in addition to winning a big hit.

  In order to solve the above problem, the invention according to claim 1 includes a display device that displays a symbol variation game performed by varying a plurality of types of symbols, and the display result of the symbol variation game is a jackpot display result. In such a case, in a gaming machine equipped with a notice effect execution means for executing a big hit notice effect during the symbol variation game, the player is given a big hit game. If the determination result is affirmative, if the determination result is affirmative, a reach effect is performed as a game effect in the symbol variation game, and a jackpot determination means for determining a jackpot effect for deriving a jackpot display result in the reach effect, and Probability variation that changes the probability of jackpot determination that occurs when the determination result of the jackpot determination means is positive, the probability that the jackpot determination means determines positively from low probability to high probability A big hit type determining means for determining from among a plurality of types of big hits including a probable big hit that gives a positive probability and a non-probable variable big hit with a low probability of affirmative determination by the big hit determining means, and the determination result of the big hit determining means In the case of affirmation, based on the type of jackpot determined by the jackpot type determining means, jackpot symbol determining means for determining a symbol that forms a jackpot symbol combination to be displayed on the display device as the jackpot display result deterministically; , A reach formation symbol determining means for determining a reach formation symbol to be derived in the reach effect in order to derive the jackpot display result or a disappointing display result, and a plurality of types of notice patterns for specifying the effect contents of the jackpot notice effect The notice pattern determining means for determining from among the notice patterns, and the notice pattern determining means in the symbol variation game are selected by the notice pattern determining means. An effect control means for controlling the notice effect execution means to execute the jackpot notice effect based on the notice pattern, and the reach formation symbol determining means is determined when the probability variation jackpot is determined as a kind of jackpot As a reach formation symbol, when the jackpot symbol combination is formed, the player can be surely recognized that the player has won the probability variation jackpot, or when the player has formed the jackpot symbol combination While it is possible to determine a non-specific symbol that cannot be definitely recognized that the winning winning jackpot has been won, when the non-probable jackpot is determined as a type of jackpot, the non-specific symbol as a reach formation symbol The notice pattern is set so that the expectation of jackpot differs for each notice pattern, and the reach formation symbol decision is made. When the jackpot determining means makes an affirmative determination during the probability changing state, the jackpot notification effect performed when the reach formation symbol is formed with the specific symbol is the jackpot expectation effect. If the reach formation symbol and the notice pattern are respectively determined so as to be performed at a high rate based on the notice pattern set to a high degree, while the jackpot judging means makes an affirmative decision during the probability change state, the reach The reach formation symbol and the notice pattern are such that the jackpot notice effect performed when the formation symbol is formed with the non-specific symbol is performed at a high rate based on the notice pattern set with a low expectation degree of the jackpot The gist is to determine each.

  According to a second aspect of the present invention, in the gaming machine according to the first aspect of the present invention, the gaming machine according to the first aspect further comprises reach determination means for determining whether or not to execute the reach effect when the determination result of the jackpot determination means is negative, The notice pattern determination means determines the notice pattern based on the reach formation symbol when the jackpot determination means is negatively determined and the reach determination means is affirmatively determined during the probability change state. To do.

  According to a third aspect of the present invention, in the gaming machine according to the first or second aspect, the presentation control means is based on the determined notice pattern when the notice pattern is determined by the notice pattern determining means. The gist is to cause the notice effect execution means to execute the jackpot notice effect before the reach formation.

  According to the present invention, by determining the content of the jackpot notice effect in consideration of the type of reach formation symbol, when the reach is formed by a specific symbol, in addition to winning the jackpot, Expectation can be given to being granted.

It is assembled as possible. On the front side of the front frame 14 and the game area 13 a of the game board 13, a decoration lamp 16 that performs a light emission effect by light emission (lighting (flashing)) of a light emitter (LED, lamp, etc.) is provided. A speaker 17 that outputs various sounds and performs a game effect based on the sound output is arranged 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.

  As shown in FIG. 2, an effect display device 20 with various displays and various decorations is attached to the approximate center of the game area 13 a of the game board 13. Also, in the lower right part of the effect display device 20, a special figure display device H0 is arranged as a display device for displaying a symbol variation game performed by varying a special symbol (special figure). The special symbol is a notification symbol indicating the result of the internal lottery (big hit lottery) whether or not the big hit. In addition, a variable display H2 as a display device is provided in the approximate center of the effect display device 20. The variable display H2 includes a symbol variation game performed by varying a plurality of symbol sequences (three columns in this embodiment), and various display effects (game effects) executed in association with the game are images. It is displayed. In the present embodiment, in the symbol variation game of the variable display H2, a symbol combination composed of a plurality of columns (three columns in the present embodiment) is derived. Note that the symbol change game of the variable display H2 is performed using decorative symbols (hereinafter referred to as decorative symbols) for diversifying display effects.

  In addition, in the variable display H2, a display effect based on a variation image (or image display) is performed, and a symbol variation game for displaying a symbol combination by varying a plurality of types of symbols in a plurality of columns is executed. Furthermore, in the variable display H2, a display effect related to the symbol variation game executed on the special figure display H0 is performed. In the special symbol display device H0 and the variable display device 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 decoration diagram are displayed in a fixed stop state at the same time). Then, on the variable display H2 and the special symbol display H0, symbols that can recognize a big hit or a loss at the same time by the end of the symbol variation game are displayed on the fixed stop based on the lottery result of the big hit lottery.

  In the present embodiment, the special figure display H0 selects one special figure corresponding to the lottery result of the big hit lottery from a plurality of types of special figures, and the selected special figure is displayed when the symbol variation game is completed. The fixed stop is displayed. A plurality of types of special figures in this embodiment are classified into a jackpot symbol that can recognize a jackpot (corresponding to a jackpot display result) and a missing symbol that can recognize a miss.

  The symbol variation game of the variable display H2 is executed in association with the variation display result of the symbol variation game of the special symbol display H0 being executed, and the variation display result of the decoration corresponding to the variation display result of the special diagram Is derived. Specifically, in the variable display H2, when the big hit lottery is won, the symbol combination of the decorative figure corresponding to the big win symbol derived to the special figure display H0 is fixedly stopped and displayed. For example, there is a combination ([111] or the like) in which all the rows (3 rows) of the decorations correspond to the jackpot symbol. On the other hand, in the variable display H2, when the big hit lottery is not won, the symbol combination of the decorative pattern corresponding to the off symbol derived to the special symbol display H0 is confirmed and stopped. For example, a combination of decorative patterns corresponding to the out-of-pattern symbol is a combination in which the decorative drawings in all rows (three rows) do not become the same decorative drawing ([124], etc.) There are combinations (such as [221] and [112]) in which one row of decorative drawings is a different decorative drawing. In the present embodiment, on the variable display H2, a pattern imitating the numbers [1] to [9] is displayed as a decorative drawing for each column.

  Further, in the pachinko machine 10 of the present embodiment, the display area (image display surface) of the variable display H2 is formed larger than the display area of the special-purpose display H0 so that the variable display H2 stands out in front of the player. Is arranged. For this reason, the player pays attention to the display content of the variable display H2 in which the display effect (for example, the reach effect or the notice effect) is performed by various images in front of his / her own eyes than the special-purpose display H0. A big hit or loss is recognized from the symbol combination derived and stopped in the symbol variation game of the variable display H2. In the present embodiment, when the symbol variation game of the variable display H2 is started, each column is variably displayed along a predetermined variation direction (vertical scroll direction). When the symbol variation game starts (when each column begins to vary), the left column (left symbol) → the right column (right symbol) → the middle column (middle symbol) as viewed from the player side in the variable display H2. The fluctuation stops in order. When the left symbol and right symbol displayed by the change stop are the same symbol, a reach is formed and the reach is recognized from the symbol combination ([1 ↓ 1] etc., "↓" indicates that the symbol is changing). obtain. In the reach, symbols of a specific column (left column and right column in this embodiment) are displayed as the same symbol among a plurality of columns, and columns other than the specific column (middle column in this embodiment) are displayed in a variable manner. It is a state that has been.

  As shown in FIGS. 1 and 2, an upper start winning opening 25 having a entrance 25 a through which a game ball can always enter is disposed below the effect display device 20. An upper start sensor SE1 (shown in FIG. 4) for detecting a game ball that has entered is provided in the depth of the upper start winning opening 25. The upper start winning opening 25 can give a starting condition for the symbol variation game by detecting a game ball that has entered, and can also give a payout condition for a game ball as a predetermined number of prize balls.

  Also, below the upper start winning opening 25, a ball opening 27a into which a game ball can enter and an opening / closing blade (normal electric combination) that opens and closes by the operation of a normal electric accessory solenoid SOL1 (shown in FIG. 4). And a lower start winning opening 27 provided with an object 26. In FIG. 2, the open / close blade 26 opened is indicated by a solid line, and the open / close blade 26 closed is indicated by a two-dot broken line. On the other hand, a lower start port sensor SE2 (shown in FIG. 4) for detecting a game ball that has entered is provided behind the lower start winning port 27. The lower start winning port 27 can give a starting condition for the symbol variation game by detecting a game ball that has entered, and can also give a payout condition for a game ball as a predetermined number of winning balls. In addition, the entrance 27a of the lower start winning opening 27 is normally closed when the opening / closing blade 26 is closed, and is in a state where entry is not possible (a state in which entry is restricted). Then, when a predetermined opening condition is satisfied, the entrance 27a is opened once or a plurality of times during a predetermined opening time by operating the opening / closing blade 26 from the closed state to the open state. That is, a state in which a game ball can enter in a state where the entrance 27a is opened (a state where entry is permitted) is established. The upper start winning opening 25 and the lower start winning opening 27 are arranged side by side along the flow-down direction (vertical direction) of the game ball launched into the game area 13 a of the game board 13.

  As shown in FIG. 1, below the lower start winning port 27, there is a large winning port 29 provided with a large winning port door 28 that opens and closes by the operation of a large winning port solenoid SOL2 (shown in FIG. 4). It is arranged. A count switch SW3 (shown in FIG. 4) for detecting a game ball that has entered the ball is provided in the back of the big winning opening 29. The big winning opening 29 can give a condition for paying out game balls as a predetermined number of prize balls by detecting the game balls that have entered. When the jackpot game is awarded, the jackpot door 29 is opened by opening the jackpot door 28 according to the kind of the jackpot game that is given, and the entrance of the game ball is permitted by the opening. The For this reason, the player can obtain a chance to acquire a winning ball corresponding to the number of gaming balls that have entered the big winning opening 29. In this embodiment, the big hit game is advantageous to the player because a chance to win a prize ball is obtained.

  The big hit game is started after the big win symbol is determined by the internal lottery, the big hit symbol is confirmed and stopped in the symbol variation 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 stage, the round game in which the grand prize opening 29 is opened by the opening operation of the grand prize opening door 28 is set to a predetermined number of rounds (upper limit round number) as a predetermined upper limit (15 times in the present embodiment), a plurality of times. Done. One round game is either that a predetermined round game time has elapsed since the start of the round game, or that a predetermined maximum number of game balls have entered in one round game. The process ends when the end condition is satisfied. In addition, after the end of one round game, the next round game is performed with a predetermined interval time in between. The big hit game is ended after an ending effect indicating the end of the big hit game is performed after the end of the round game of the specified number of rounds.

  In addition, as shown in FIG. 2, a hold indicator R is disposed on the right side of the special-purpose indicator H <b> 0 in the effect display device 20. The hold indicator R enters the upper start winning opening 25 and the lower start winning opening 27, and becomes the start holding ball and stores the number of start holding balls stored in the machine (RAM 30c) (hereinafter referred to as “holding storage number”). The number of symbol variation games being held is notified by the display content of the holding display R. The number of reserved memories is incremented by 1 (+1) when a game ball enters the upper start prize opening 25 or the lower start prize opening 27, and is decremented by 1 (-1) when the symbol variation game is started. Then, when a game ball enters the upper start winning opening 25 or the lower start winning opening 27 during the symbol variation game, the reserved memory number is further added (+1) and accumulated up to a predetermined upper limit number (4 in this embodiment). Is done. The hold indicator R is composed of a plurality of (four) light emitting means including a first hold lamp R1, a second hold lamp R2, a third hold lamp R3, and a fourth hold lamp R4. For example, when the first hold lamp R1 is lit, it is informed that one symbol variation game is on hold.

  As shown in FIG. 1, a 7-segment normal symbol display H <b> 10 is disposed on the left side of the effect display device 20. In the normal symbol display H10, a plurality of types of normal symbols (hereinafter sometimes referred to as “general symbols”) different from the symbols (special symbols and decorations) used in the symbol variation game are changed and the normal symbols are displayed. The normal symbol variation game for deriving the above is executed. Hereinafter, the normal symbol variation game may be referred to as “ordinary game”. In the present embodiment, one common figure is derived in the common figure game, and the types of the common figure are “0” and “1”.

  The player can recognize the per-normal figure or the off-normal figure from the normal figure that is finally displayed in a fixed stop in the normal game. When the normal symbol displayed on the normal symbol display H10 is confirmed and stopped, the common symbol per unit can be recognized. The universal map which can recognize this universal map is the display result of the hit. When the display result per usual map is displayed as a fixed stop, the player is given a gaming state per common figure. In addition, when the usual figure displayed on the normal symbol display H10 is confirmed and stopped, the deviation from the usual figure can be recognized. The usual figure which can recognize this deviation is a display result of deviation.

  As shown in FIG. 1, an operation gate 23 is disposed on the left side of the effect display device 20. Behind the operation gate 23, a gate sensor SE4 (shown in FIG. 4) that detects a game ball that has passed through the ball is provided. The operation gate 23 can give the start condition for the usual game, triggered by the detection of the entry of the game ball (passage detection). The usual game is an effect performed to derive a lottery result indicating whether or not the opening / closing blades 26 of the lower start winning opening 27 are opened (whether a game ball can be inserted into the lower starting winning opening 27). It is. As described above, the lower start winning opening 27 is normally closed by the opening / closing blade 26, but the opening / closing blade 26 is opened when a game state is given per game. It will be in an open state and can enter a game ball. In other words, the specific opening condition described above is a win for a lottery per ordinary figure. Then, when the game state is given per usual figure, it becomes easier to enter the game ball into the lower start winning opening 27 by opening the opening / closing blade 26.

  In addition, the pachinko machine 10 of the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function. The probability variation function is a function that provides a probability variation state in which the probability of winning a lottery (winning probability) varies from a normal probability having a low probability (normal state) to a high probability after the jackpot game ends. The probabilistic state is given until the next big hit occurs. In addition, if a probability variation state is given, the probability of winning a lottery fluctuates with a high probability and it is easy for a jackpot to occur. While playing games. On the other hand, a big hit that is not given a probability variation state is a non-probable variation big hit.

  Moreover, in the pachinko machine 10 of the present embodiment, among the decorations displayed on the variable display H2, jackpot symbol combinations [111], [333], [555], [777], formed by odd symbols, And [999] are set as a symbol combination (a jackpot symbol (specific symbol) for which the probability variation is confirmed) that can definitely recognize the probability variation jackpot. On the other hand, in the pachinko machine 10 of the present embodiment, among the decorative symbols displayed on the variable display H2, jackpot symbol combinations [222], [444], [666], and [888] formed by even symbols. Are set as symbol combinations that can be recognized as either probability variation big hits or non-probable variation big hits (probability undetermined big hit symbols (non-specific symbols)). That is, the symbol combinations [111], [333], [555], [777], and [999] of the jackpot by the decorative drawing are derived in the symbol variation game of the variable display H2 when the probability variation jackpot is determined. It is considered a possible combination. In addition, in the combination [222], [444], [666], and [888] of the jackpot by the decorative drawing, regardless of whether the probability variation big hit or the non-probability big hit is determined, the symbol variation game of the variable display H2 It is a combination that can be derived by.

  Further, the pachinko machine 10 of the present embodiment has a function of shortening the variation time (hereinafter referred to as “variation”). The variable function is a variable state in which the variation time of the normal game is shortened and the random probability (winning probability) of the general game based on the passage of the operation gate 23 varies from a normal probability having a low probability to a high probability. Is a function for granting as a privilege. Also, the open / close blades 26 of the lower start winning opening 27 are opened and closed with different operation patterns when winning in the normal game, depending on whether the variable state is given or not. It has become. For example, in the present embodiment, when the normal game is won when the variable state is not given, the open / close blade 26 opens once, and the open state is maintained until 0.3 (seconds) elapses. Is supposed to maintain. On the other hand, when the normal game is won when the variable state is given, the number of times the opening / closing blade 26 is opened increases to 3 times and 1.4 (seconds) after the opening time is released in one opening. ) (A long time compared with the normal state) is maintained until it has passed. In other words, the open / close blade 26 is set to operate more advantageously for the player when the variable state is applied, compared to the state where the variable state is not applied. During the variable speed state, the opening / closing blade 26 operates favorably for the player, and the rate of entry of game balls into the lower start winning opening 27 per unit time is improved. Become. The variable state is given until a predetermined number of symbol variation games are executed, or until a big hit is generated before the number of times is reached. It should be noted that the number of times that the short / short state is given varies depending on the gaming state at the time of winning the jackpot.

Next, the jackpot game defined in the pachinko machine 10 of this embodiment will be described in detail based on FIG.
In the pachinko machine 10 according to the present embodiment, when the big hit lottery is won, one big hit game is determined from a plurality of types of big hit games shown in FIG. 3, and the determined big hit game is given. Yes. Which of the big hit games among a plurality of types of big hit games is determined according to the type of special figure (big hit symbol) that is determined when the big hit lottery is won.

  In the present embodiment, 100 types of special symbol jackpot symbols displayed on the special symbol display H0 are classified into three groups of a symbol a, a symbol b, and a symbol c as shown in FIG. Specifically, 50 types of jackpot symbols are classified in symbol a, while 25 types of jackpot symbols are classified in symbols b and c.

  The jackpot game that is awarded when the jackpot symbol that is classified as symbol a is displayed on the special chart display H0 has the specified number of rounds set to “15” and gives a probable state after the jackpot game ends. It is a 15 round jackpot game (the lottery probability state of the jackpot lottery is changed to a high probability lottery state). Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol a is displayed on the special chart display H0 is referred to as “normal probability variable jackpot game”. In the normal probability big hit game, the upper limit number of balls (specified number) for one round game is set to “9 balls”.

  Further, in the 15 round games in the normal probability variation big hit game, it is set so that the big winning opening door 28 of the big winning opening 29 is opened “once” in each round game. In addition, in the normal probability change 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 variable state is given until the end of the probability change state. In FIG. 3, the case where the variable state is given until the next big hit occurs after the probability variable state is given is described as “no limit”.

  The jackpot game that is awarded when the jackpot symbol classified as the symbol b is displayed on the special chart display H0 has the specified number of rounds set to "15" and gives a probable change state after the jackpot game ends. It is a 15 round jackpot game. The jackpot game given when the jackpot symbol classified as the symbol b is displayed on the special symbol display H0 is given a probable change state after the jackpot game is finished, regardless of the gaming state at the time of winning the jackpot lottery. At the same time, after the big hit game is over, a variable state is given until 100 symbol variation games are over. Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol b is displayed on the special chart display H0 will be referred to as “probability jackpot game with 100 times change”. In the probable big hit game with 100 times of short and long, the upper limit number of balls (specified number) for one round game is set to “9 balls”. Further, in the 15 round games in the probable big hit game with 100 times change, the big winning opening door 28 of the big winning opening 29 is set to be opened “once” in each round game.

  The jackpot game that is awarded when the jackpot symbol classified as symbol c is displayed on the special chart display H0 has the specified number of rounds set to "15" and gives a probable state after the jackpot game ends. It is a 15 round jackpot game that does not (provides an uncertain change state or sets the lottery probability state of the jackpot lottery to a low probability lottery state). Hereinafter, the jackpot game given when the jackpot symbol classified as the symbol c is displayed on the special chart display H0 will be referred to as “non-probable big hit game”. Further, in the 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 15 round games in the non-probability big hit game, it is set so that the big winning opening 29 (the big winning opening door 28) is opened “once” in each round game. In the non-probable big hit game, regardless of the game state at the time of winning the big hit lottery, the probable state is not given after the big hit game ends, and the predetermined number of times (100 in this embodiment) is changed as the upper limit number. A short state is given.

In the present embodiment, the normal probability variation big hit is the first probability variation big hit, and the probability variation big hit with the 100 times variation is the second probability variation big hit.
Next, the control configuration of the pachinko machine 10 will be described with reference to FIG.

  A main control board 30 that controls the entire pachinko machine 10 is mounted on the back side of the pachinko machine 10. The main control board 30 executes various processes for controlling the entire pachinko 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). 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 a 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 capable of executing control operations in a predetermined order. The main CPU 30a is connected to a ROM 30b that stores a control program for the main CPU 30a and a RAM 30c that can write and call necessary data. Further, an upper start port sensor SE1, a lower start port sensor SE2, a gate sensor SE4, and a count switch SW3 are connected to the main CPU 30a. The main CPU 30a is connected to a special symbol display H0, a normal symbol display H10, and a hold indicator R. The main CPU 30a is connected to a normal electric accessory solenoid SOL1 and a special prize opening solenoid SOL2.

  The main CPU 30a sequentially updates the values of various random numbers such as a jackpot determination random number, a jackpot design random number, and a universal hit determination random number for each predetermined period. Then, the main CPU 30a rewrites the value before update by setting the updated value in the setting area of the RAM 30c. The big hit determination random number is a random number used in the big hit lottery (big hit determination) whether or not to make a big hit. The jackpot symbol random number is a random number used to determine a special symbol to be displayed on the special symbol display device H0 in the case of a big hit, and is assigned to each jackpot symbol by a predetermined number. Moreover, the hit determination random number for a common figure is a random number used in the lottery per common figure (determination per common figure) for determining whether or not to make a hit per common figure. Further, the main CPU 30a of the present embodiment 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 ROM 30b stores a main control program for controlling the pachinko machine 10, various determination values (such as a big hit determination value, a normal hit determination value), a plurality of types of variation patterns, and the like. The variation pattern indicates a pattern that is a base of a game effect (display effect, light emission effect, sound effect) from the start of the symbol change game to the end of the game. In the variation pattern, a game production effect time (variation time) is defined for each variation pattern.

  The variation pattern is composed of a variation pattern for a jackpot effect selected when winning the jackpot lottery, and a variation pattern for a loss effect selected in the case of a loss that has not won the jackpot lottery. The fluctuation pattern for outlier production includes a fluctuation pattern with reach (fluctuation pattern for outlier reach production) that will eventually become a deviation after the reach is formed, and a fluctuation pattern without reach that does not form a reach. (Variation pattern for off-stage production).

FIG. 5 shows a part of variation patterns that can be selected in the pachinko machine 10 of the present embodiment.
In the present embodiment, three types of variation patterns P1, P2, and P9 are prepared as variation patterns for the offending effect. These fluctuation patterns P1, P2, and P9 have fluctuation contents of “normal fluctuation”, “shortening fluctuation”, and “super-shortening fluctuation”. “Normal variation” means that after a symbol variation game is started, variation is stopped in accordance with a predetermined variation stop order (for example, left column → right column → middle column) and symbols are derived in each column. It is off-line production. “Abbreviated fluctuation” is an off-stage effect in which the fluctuation time is set shorter than “normal fluctuation”, and the fluctuation of each column is stopped at substantially the same timing and the symbol is derived in each column. “Super-shortening variation” is an extraordinary effect only for the variable state, and the variation time is set shorter than “shortening variation”, and the variation of each column is stopped at almost the same timing, and the symbol is derived to each column. It is an offense production. In the present embodiment, the fluctuation pattern P1, P2, P9 has a fluctuation time that is shorter in the fluctuation pattern P2 (fluctuation time TB) than in the fluctuation pattern P1 (fluctuation time TA), and is more variable than the fluctuation pattern P2. The fluctuation time TC) is shorter. In the present embodiment, the variation patterns P1 and P2 are selected according to the number of reserved start storages (0 to 3) subtracted with the start of the symbol variation game.

  The fluctuation patterns P3, P5, and P7 are fluctuation patterns for outlier reach effects. Further, the variation patterns P4 and P6 are variation patterns for a big hit effect that can be selected when one of a normal probability variation big hit, a probability variation big hit with 100 times variation, and a non-probable variation big hit is won. However, when winning the normal probability variation big hit, it is difficult to select the variation pattern P4. On the other hand, the variation pattern P8 is a variation pattern for a jackpot effect that can be selected when a normal probability variation jackpot is won. In addition, the fluctuation times of the fluctuation patterns P3 to P8 are longer in the fluctuation patterns P5 and P6 (fluctuation time T2) than in the fluctuation patterns P3 and P4 (fluctuation time T1), and the fluctuation patterns P7 and P8 are longer than the fluctuation patterns P5 and P6. (Fluctuation time T3) is longer. In addition, the same contents (contents with the theme of the character K1 in the present embodiment) are set as the effect contents of the reach effect in the change patterns P3 and P4, while the reach effect is provided in the change patterns P5 and P6. The same contents (contents with the theme of the character K2 in this embodiment) are set as the production contents. In the variation patterns P7 and P8, the same contents (contents with the theme of the character K3 in this embodiment) are set as the contents of the reach effect.

  The jackpot determination value is a determination value used in the jackpot lottery, and is determined from numerical values that can be taken by the jackpot determination random number. In addition, the big hit judgment value is a big hit judgment value for low probability used in the big hit lottery when the gaming state is non-probable change state (low probability lottery state), and a big hit when the gaming state is probable change state (high probability lottery state) There is a jackpot judgment value for high probability used in the lottery. In the pachinko machine 10 of the present embodiment, the possible values of the random number for determining the big hit are set to 600 integers from “0 (zero)” to “599”, and the big hit for low probability is selected from the values. Two values are set as the determination values, and the ratio at which the big hit determination is positively determined in the uncertain change state, that is, the winning probability of the big hit lottery is 2/600 (1/300). In addition, 20 values are set as the high probability jackpot determination value, and the ratio at which the big hit determination is positively determined in the probability variation state, that is, the winning probability of the big hit lottery is 20/600 (1/30) It becomes.

  The common figure determination value is a determination value used in a lottery per general figure, and is determined from the possible values of random numbers for general use. The figure per base figure is the low probability per base figure used in the lottery per lot when the gaming state is non-variable and the lot per lot when the game state is short. There is a judgment value per common figure for high probability to be used. For example, the number of possible random numbers for hit determination for common maps is set to a total of 251 integers from “0 (zero)” to “250”, from which the low-probability hit per-map determination When one value is set as the value, the rate at which the determination per common figure is positively determined in the non-variable state, that is, the winning probability is 1/251. In addition, when 250 values are set as the high probability common figure determination value, the rate at which the normal figure determination is positively determined in the variable state, that is, the winning probability is 250/251.

  In addition, the ROM 30b stores the effect patterns in the big hit game, classified into an opening effect, a round effect, and an ending effect. The opening effect is an effect indicating the start of the big hit game, and the ending effect is an effect indicating the end of the big hit game after the end of the prescribed number of round games. The round effect is an effect indicating the number of rounds of the round game being executed, and the effect itself executed during the round game.

  The RAM 30c stores (sets) various types of information (such as various flags, various types of pending storage, timer values, and count values) that are appropriately rewritten during the operation of the pachinko machine 10.

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 that can execute control operations in a predetermined procedure, a ROM 31b that stores a control program for the overall CPU 31a, and a RAM 31c that can write and read necessary data. In addition, a ROM 31b and a RAM 31c are connected to the overall CPU 31a. The general CPU 31a is equipped with a timer function, and measures time at a predetermined timing (for example, timing at which the symbol variation game is started).

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 that can execute a control operation in a predetermined procedure, a ROM 32b that stores a control program for the sub CPU 32a, and a RAM 32c that can write and read necessary data. An effect display device 20 (variable display H2) is connected to the sub CPU 32a. Further, the sub CPU 32a of the present embodiment has a timer function, and measures time at a predetermined timing (for example, a timing at which a symbol variation game is started). The ROM 32b stores various image data (image data such as symbols, backgrounds, characters, characters, etc.).

Hereinafter, control contents executed by the main control board 30 (main CPU 30a), the overall control board 31 (overall CPU 31a), and the display control board 32 (sub CPU 32a) will be described.
First, the control contents of the main control board 30 will be described.

  When the main CPU 30a of the main control board 30 enters a game ball into the upper start winning port 25 or the lower start winning port 27 and inputs detection signals output from the start port sensors SE1 and SE2 that detect the game ball, the RAM 30c is input. It is determined whether or not the stored storage number is less than the upper limit number (4 in the present embodiment).

  If the determination result of the hold determination is affirmative (holding memory count <4), the main CPU 30a adds 1 (+1) to the holding memory count and rewrites the holding memory count. Further, when the main CPU 30a makes an affirmative determination of the hold determination, the main CPU 30a acquires the value of the big hit determination random number and the value of the big hit symbol random number from the RAM 30c, and associates the values with the number of reserved storage and stores the predetermined value in the RAM 30c. Store in the area. When the determination result of the hold determination is negative (holding memory number = 4), the main CPU 30a does not rewrite the holding memory number exceeding the upper limit number, and also determines the big hit determination random number value and the big hit symbol random number value. Do not get.

  The main CPU 30a reads out the jackpot determination random number value stored in the predetermined storage area of the RAM 30c immediately before the start of the symbol variation game, and the read jackpot determination random number value and the jackpot determination stored in the ROM 30b. The value is compared, and a big hit determination (big hit lottery) is performed to determine whether or not the big hit. In the jackpot determination, the main CPU 30a compares the jackpot determination value for low probability with the value of the random number for jackpot determination when the gaming state is the normal state, and when the gaming state is the probability change state, The jackpot determination value for probability is compared with the value of the random number for jackpot determination.

  When the determination result of the big hit determination is affirmative (the value of the random number for big hit determination matches the big hit determination value), the main CPU 30a determines the big hit. Specifically, the main CPU 30a determines a jackpot symbol (special symbol) to be confirmed and stopped in the symbol variation game based on the value of the jackpot symbol random number. The main CPU 30a that has determined the big hit selects and determines one variation pattern from among the variation patterns for the big hit effect that can be selected when the big hit is won.

  In addition, when the determination result of the big hit determination is negative (the value of the big hit determination random number does not match the big hit determination value), the main CPU 30a performs a reach determination as to whether or not to make a loss reach. When the determination result of the reach determination is affirmative, the main CPU 30a determines the outlier reach, determines the outlier symbol (special symbol) to be confirmed and stopped in the symbol variation game, and selects one of the variation patterns for the outlier reach effect. Select and determine one variation pattern. The main CPU 30a in this embodiment makes an affirmative determination of reach determination with a probability of 1/10.

  In addition, the main CPU 30a determines the outage when the determination result of the reach determination is negative, determines the out symbol (special image) to be confirmed and stopped in the symbol variation game, and the variation for the off-direction effect that can be selected at the time of the outage. One variation pattern is selected from the patterns and determined.

  The main CPU 30a having determined the special figure and the variation pattern outputs a predetermined control command to the overall control board 31 (overall CPU 31a) at a predetermined timing. Specifically, the main CPU 30a first outputs a variation pattern designation command for instructing the variation pattern and instructing the start of the symbol variation game. Next, the main CPU 30a outputs a special symbol stop designating command for instructing the special symbol. Then, the main CPU 30a outputs a symbol stop command for instructing the end of the symbol variation game (determination of symbol determination) when the variation time determined in the instructed variation pattern has elapsed. Further, the main CPU 30a subtracts 1 (-1) from the reserved memory number at the start of the symbol variation game, and rewrites the reserved memory number. And main CPU30a controls the display content of the special figure display H0 with the start of a symbol change game. That is, the main CPU 30a starts the variation of the special figure by the start of the symbol variation game, and confirms and stops the special symbol (big hit symbol or off symbol) determined when the variation time set in the determined variation pattern has elapsed. Let

  In the pachinko machine 10 of the present embodiment, the winning probability of the big hit lottery in the non-probable variation state is 1/300, and the winning probability of the big hit lottery in the probabilistic state is 1/30. In addition, when winning the big hit lottery, the probability of becoming a normal probability change big hit or a probability change big hit with 100 times change is 75/100 (50 + 25). Therefore, the probability that a single symbol variation game will be a promising big hit is determined by the product of “the winning probability of the big win lottery” and “the ratio of the normal probable big win or the probable big hit with 100 time changes when the big win is reached”. It is done. That is, the probability in the non-probable change state is (1/300) × (75/100) × 100 = 0.250 (%). Further, the probability in the probability variation state is (1/30) × (75/100) × 100 = 2.500 (%). On the other hand, the probability that one symbol variation game will become a non-probable big hit is obtained by the product of “winning probability of big hit lottery” and “the ratio of non-probable big hit when a big win”. That is, the probability in the non-probable change state is (1/300) × (25/100) × 100 = 0.0833 (%). Further, the probability in the probability variation state is (1/30) × (25/100) × 100 = 0.8333 (%). Further, the probability that the lost reach effect is executed in one symbol variation game is obtained by the product of “probability of being lost in jackpot lottery” and “probability of affirmative determination of reach”. That is, the probability in the non-probable change state is (299/300) × (1/10) × 100 = 9.9666 (%). Further, the probability in the probability variation state is (29/30) × (1/10) × 100 = 9.6666 (%). The following explanation and the results of the calculation formulas used in FIGS. 8, 9, 14, and 15 are rounded off to the fourth decimal place.

Next, as the control content executed by the main control board 30, the control content related to the execution of the big hit game will be described.
When determining the big hit, the main CPU 30a starts the control of the big hit game when the big hit is reached after the end of the symbol variation game based on the determined fluctuation pattern, and controls the central control board 31 (the central CPU 31a) with a predetermined A control command is output at a predetermined timing. Specifically, the main CPU 30a first outputs an opening command for designating an effect pattern in the opening effect. Next, the main CPU 30a outputs a round start command for designating an effect pattern in each round effect at the start of each round game. At that time, the main CPU 30a opens the big prize opening door 28 for each round game, and closes the big prize opening door 28 after a predetermined time has elapsed or after a predetermined number of game balls have won the big prize opening 29. Then, the main CPU 30a outputs a round end command for notifying the end of each round effect and the interval effect between round games. The main CPU 30a repeatedly executes this round game for 15 rounds. Then, after the end of the final round, the main CPU 30a outputs an ending command for designating an effect pattern in the ending effect, and ends the big hit game.

  In addition, the main CPU 30a that ended the jackpot game executes a probability change grant determination as to whether or not to give a probability change state after the jackpot game ends. Then, the main CPU 30a gives a certain change state when the determination result is affirmative. On the other hand, when the determination result is negative, the main CPU 30a does not give a certain change state. In the present embodiment, when the probability variation big hit is won, the probability variation grant determination is affirmed. On the other hand, in the present embodiment, when the non-probable change big hit is won, the determination of the probability change grant determination is negative.

  In the present embodiment, the main CPU 30a that performs jackpot determination is the jackpot determination means. Further, the main CPU 30a that determines the type of jackpot is a jackpot type determining means. Further, the main CPU 30a that executes reach determination serves as reach determination means.

Next, the control contents executed by the overall control board 31 (the overall CPU 31a) according to the overall control program will be described.
When the overall CPU 31a of the overall control board 31 receives the change pattern designation command, it outputs the change pattern designation command to the display control board 32, the lamp control board 33, and the sound control board 34, respectively. When the general CPU 31a inputs a stop symbol designation command for a special symbol, the overall CPU 31a forms a symbol combination that causes the variable display H2 to stop display according to the special symbol stop symbol designation corresponding to the stop symbol designation command. To decide. Further, when the general CPU 31a inputs a special symbol stop symbol designation command, the general CPU 31a stores the command in the RAM 31c. Further, when the overall CPU 31a inputs a symbol stop command, the overall CPU 31a outputs the command to the display control board 32, the lamp control board 33, and the sound control board 34, respectively. Further, when the opening CPU, the round start command, the round end command, and the ending command are input from the main control board 30, the general CPU 31a relays these commands to display control board 32, lamp control board 33, and voice control board. 34 respectively.

  In addition, when the stop symbol (special symbol) designated by the stop symbol designation command is a jackpot symbol corresponding to the probability variation jackpot, the overall CPU 31a sets a probability variation state to be given to the RAM 31c. On the other hand, if the stop symbol (special symbol) designated by the stop symbol designation command is a big hit symbol corresponding to a non-probable change big hit, the overall CPU 31a sets that the normal state (non-probability change state) is given to the RAM 31c. .

  When the stop symbol (special symbol) designated by the stop symbol designation command is a big hit symbol, the overall CPU 31a uses a combination of jackpot symbols that can recognize the big hit as a symbol symbol combination for all the rows. To decide. At this time, the overall CPU 31a determines a jackpot symbol combination from [1] to [9] according to the specified variation pattern type and special figure type.

FIG. 6 shows a jackpot symbol combination determination table.
The table shown in FIG. 6 is stored in the ROM 31b. In the table, the decorative drawings from [111] to [999] are displayed for the variation patterns P4, P6, and P8 for the jackpot effect according to the type of the jackpot designated by the stop symbol designation command for the special figure. A random number (a total of 151 kinds of integers from 0 to 150) is assigned to a predetermined number so that any one of the jackpot combinations can be selected. Moreover, in the pachinko machine 10 of this embodiment, the stop symbol designation command for the decoration drawing which designates the decoration drawing derived | led-out to each row | line is set. Specifically, the left stop symbol designation command for the decoration drawing that specifies the decoration drawing to be derived in the left column, the right stop symbol designation command for the decoration drawing that designates the decoration drawing to be derived in the right column, and the middle column A decoration stop design designation command for designating the decoration drawing to be derived is set, and these commands are composed of 2-byte control data composed of an upper byte and a lower byte. The left stop symbol designating command for decoration is composed of “90H” in the upper byte and “11H”, “0FH”, “0DH”, “0BH”, “09H”, “07H” in the lower byte. , “05H”, “03H”, and “01H”, which specify decorative drawings [1] to [9], respectively.

  In addition, the right stop symbol designation command for the decoration drawing includes the upper byte of “91H” and the lower bytes of “01H”, “03H”, “05H”, “07H”, “09H”, “ It consists of “0BH”, “0DH”, “0FH”, and “11H”, and specifies decorative drawings [1] to [9], respectively. Further, the middle stop symbol designating command for decoration drawing has an upper byte of “92H” and lower bytes of “01H”, “03H”, “05H”, “07H”, “09H”, “ 0BH "," 0DH "," 0FH "," 11H ".

  In the jackpot symbol combination determination table (FIG. 6), when a special symbol stop symbol designating command for designating a normal probability variation jackpot (corresponding to symbol a) and a variation pattern designating command for designating the variation pattern P4 are input. As a jackpot symbol combination, any one of [222], [444], [666], [888], and [999] can be selected. And it is set so that the selection probability of [222] is the highest among even symbols. Further, when a special symbol stop symbol designating command for designating a normal probability variation jackpot and a variation pattern designating command for designating the variation pattern P6 or variation pattern P8 are input, [111] to [999] Any one of them can be selected.

  Also, a stop symbol designating command for a special figure that designates a probable big hit (corresponding to symbol b) or a non-probable big jackpot (corresponding to symbol c) with 100 times variation, and a variation pattern designation that designates variation patterns P4 and P6. When a command is input, any one of [222], [444], [666], and [888] can be selected as a jackpot symbol combination. Therefore, when the normal probability variation big hit is won internally, [111], [333], [555], [777], and [999] can be selected as the big win symbol combination. In addition, the variation pattern P4 (see FIG. 6) for the jackpot effect is set so that [999] can be derived as the symbol combination for the jackpot, while the variation pattern P3 for the loss reach effect (FIG. 7). Reference) does not set [9] to be derived in the left and right columns as a symbol combination of outlier reach. In the variation patterns P3 and P4, the same contents (contents with the theme of the character K1) are set as the contents of the reach effect. Therefore, when [9] is derived in the left and right columns and the reach effect on the theme of the character K1 is executed, the contents of the reach effect are only visually recognized even before the big hit symbol combination is confirmed and stopped. It has become clear that you have won the winning jackpot. On the other hand, when [222], [444], [666], and [888] are selected as the jackpot symbol combination, when the jackpot symbol combination is displayed in a fixed stop state, the normal probability change big hit and 100 times shorter It is not possible to specify which jackpot has been won, whether it is a positive jackpot or a non-probable jackpot. The jackpot symbol combination is derived after the reach is formed by the decoration specified by the left stop symbol designation command for decoration and the right stop symbol designation command for decoration.

  In the pachinko machine 10 according to the present embodiment, as shown in FIG. 6, when the stop symbol (special symbol) is a big hit symbol corresponding to the normal probability variation big hit, the overall CPU 31a has an odd number of fixed stop symbols with a probability of approximately 70%. While selecting a symbol, an even symbol is determined as a fixed stop symbol with a probability of approximately 30%. When an odd symbol is selected as the fixed stop symbol, it is notified during the symbol variation game that the player has won the normal probability variation big hit. On the other hand, when an even number of symbols is selected as the confirmed stop symbol, it is notified by the promotion effect during the big hit that the normal probability variable big hit is won. The jackpot promotion effect is an effect performed during the jackpot game in order to make the player recognize the type of jackpot determined when the jackpot is won in the jackpot lottery.

  On the other hand, as shown in FIG. 6, the overall CPU 31a determines the determined big hit symbol as an even number symbol when winning with a probability variation big hit with 100 times change or a non-probable big hit. And, when the winning odds big hit with 100 times change or the non-probable big hit is won, the promotion effect during the big hit is always executed. However, even if the winning is a 100% odd-change jackpot or a non-probable jackpot, it is not reported that the jackpot is a jackpot with a promotion effect during the jackpot.

  In addition, when the stop symbol (special symbol) designated by the stop symbol designation command is an outlier symbol, and the variation pattern for the outlier reach effect is designated, the overall CPU 31a determines the symbol combination of the outlier reach. .

FIG. 7 shows an outlier reach symbol combination determination table.
The table shown in FIG. 7 is stored in the ROM 31b. In the table, [121], [232], [343], [454], [565], [676], [787], [898] with respect to the variation patterns P3, P5, and P7 for the outlier reach effect. ] And [919], a random number (a total of 151 kinds of integers from 0 to 150) is assigned by a predetermined number so that any one of the combinations of decorative drawings up to [919] can be selected. In the pachinko machine 10 according to the present embodiment, the same stop symbol designating command for decoration as the jackpot symbol combination determining table (FIG. 6) is referred to in the outlier reach symbol combination determining table (FIG. 7). It has become.

  In the outlier reach symbol combination determination table (FIG. 7), when a variation pattern designation command for designating the variation pattern P3 is input, [232], [454], [676], and [676] 898] can be selected. In addition, when a variation pattern designation command for designating the variation pattern P5 or the variation pattern P7 is input, any one of [121] to [919] can be selected as the symbol combination of the loss reach. When the variation pattern P5 or the variation pattern P7 is selected, the selection rate of the symbol combination of the outlier reach in which the left and right columns become odd symbols is lower than the symbol combination of the outlier reach in which the left and right columns become even symbols. Has been. At the same time, [919] is set to be the lowest. Therefore, at the time of detachment reach, the ratio of the symbol combinations of the divergence reach is higher in the even number symbols than in the odd number of symbols, and the probability that the symbol combination of the detachment reach indicated by [919] is formed is extremely low.

  Then, the overall CPU 31a that has determined the symbol combination of the decorative drawing from the table shown in FIG. 6 or 7 in accordance with the content specified by the special symbol stop symbol specifying command, uses the left stop symbol specifying command for decorative drawing → decorative drawing The commands are output to the display control board 32 in the order of right stop symbol designation command → decorative illustration medium stop symbol designation command. In addition, the overall CPU 31a stores the determined left stop symbol designation command for decorative drawing in the RAM 31c.

  In the pachinko machine 10 of the present embodiment, as shown in FIG. 7, the overall CPU 31a selects an odd symbol with a probability of approximately 30% as a symbol combination of outlier reach, while an even symbol with a probability of approximately 70%. decide. In addition, the overall CPU 31a, when the stop symbol (special symbol) designated by the stop symbol designation command is a loss symbol, and when the variation pattern for the off-state effect is specified, the symbol combinations of the symbols on the left and right are different. To decide.

  Therefore, in the pachinko machine 10 of the present embodiment, as shown in FIG. 8, the probability that the odd variation symbol will be a big odds jackpot in one symbol variation game is “the probability that one symbol variation game will be a big odds jackpot”. It is obtained by the product of “the ratio at which an odd number symbol is selected as a definite stop symbol when it is a probable big hit”. That is, the probability in the non-probable change state is 0.250 (%) × (70/100) = 0.175 (%). Further, the probability in the probability variation state is 2.500 (%) × (70/100) = 1.750 (%). On the other hand, in the pachinko machine 10 according to the present embodiment, the odd symbol is not selected in the case of a non-probable big hit, so the probability that the odd symbol is a non-probable big hit in one symbol variation game is 0 ( %). In addition, the probability of a probabilistic big hit with an even number of symbols in one symbol variation game is “probability that a single symbol variation game will be a promising big hit” and “even number symbols are selected as a definitive stop symbol when a probable big hit It is determined by the product of “Percentage”. That is, the probability in the non-probable change state is 0.250 (%) × (30/100) = 0.075 (%). Further, the probability in the probability variation state is 2.500 (%) × (70/100) = 0.750 (%). On the other hand, the probability of a non-probable change big hit with an even-numbered symbol in a single symbol variation game is 0.0833 (%) in the non-probabilistic state, while 0.8333 (%) in the probabilistic state. It becomes. In addition, the probability that a deviation reach is formed in an odd symbol in one symbol variation game is “the probability that a deviation reach effect is executed in one symbol variation game” and “an odd symbol is selected in the case of a loss reach. It is determined by the product of the ratio That is, the probability in the non-probable change state is 9.966 (%) × (30/100) = 2.990 (%). Further, the probability in the probability variation state is 9.666 (%) × (30/100) = 2.900 (%). On the other hand, the probability that a deviation reach is formed in an even symbol in a single symbol variation game is “the probability that a deviation reach effect is executed in one symbol variation game” and “even symbols in the case of a loss reach. It is determined by the product of the “ratio selected”. That is, the probability in the non-probable variation state is 9.966 (%) × (70/100) = 6.9766 (%). Further, the probability in the probability variation state is 9.666 (%) × (70/100) = 6.776 (%).

  Thus, in the case of a probable big hit, the probability that a big hit symbol combination is formed by an odd number of symbols is set higher than an even number of symbols. Also, the ratio of even-numbered jackpot symbol combinations formed when winning a non-probable jackpot is higher than the percentage of even-numbered jackpot symbol combinations formed when winning the odd-numbered jackpot. Is set to

Further, as shown in FIG. 9, the big hit expectation degree when the reach is applied with an odd number of symbols is obtained by the following calculation formula (1).
Expectation of jackpot when reach is reached for odd symbol = "Probability of probable big hit with odd symbol in one symbol variation game" / ("Probability of probable big hit with odd symbol in one symbol variation game" + “Probability that a slippage reach will be formed in odd symbols in one symbol variation game”) (1)
Therefore, as a big hit expectation degree when reach is applied with an odd number of symbols, the probability in the non-probability state is 0.175 (%) / (0.175 (%) + 2.990 ... (%)) × 100 = 5 5292 (%). Further, the probability in the probability variation state is 37.6344 (%). In addition, the said big hit expectation degree also shows the expectation degree which becomes a probability variation big hit. On the other hand, the jackpot expectation when the reach is applied to an even symbol is obtained by substituting the aforementioned equation (1) with an even symbol, and the probability is 2.2191 ... ( On the other hand, the probability in the probability variation state is 18.9620 (%). In addition, the probability of reaching with odd symbols is calculated as the sum of “probability of reaching out in one symbol variation game” + “probability of winning odd odds with odd symbols in one symbol variation game”. It is done. That is, the probability in the non-probabilistic state is 2.990 (%) + 0.175 (%) = 3.165 (%), while the probability in the probabilistic state is 2.900 (%). +1.750 (%) = 4.650 (%). In addition, the probability of reaching even with an even number of symbols is 6.9766 (%) + 0.075 (%) + 0.0833 (%) = 7.135 (%) while in the uncertain change state. Thus, the probability in the probability variation state is 6.7666 (%) + 0.750 (%) + 0.8333 (%) = 8.350 (%). Therefore, in the case of a big hit, the probability that a big hit symbol combination is formed by an odd number of symbols is set higher than an even number of symbols.

  As described above, in the pachinko machine 10 according to the present embodiment, in the case of a big hit, there is a higher probability that a big hit symbol combination is formed with an odd number of symbols than with an even number of symbols. In the even number design, the probability that the symbol combination of the shift reach is formed is high. As a result, it is understood that when a reach symbol with an even symbol is derived, the probability of being out of place is higher than the probability of being a big hit.

  Further, the overall CPU 31a sets the production mode based on the final stop symbol and the gaming state. The effect mode is an effect that suggests the game state to the player. In the present embodiment, there are three effect modes, and at least the background image is changed for each effect mode. The effect mode of the present embodiment includes a normal mode that allows the player to recognize that the probability that the probability variation state is not given is high. In the normal mode of the present embodiment, the character string “in normal mode” is displayed on the variable display H2.

  In addition, the effect mode includes a probability change mode that definitely indicates that the probability change state is given. In the probability variation mode of the present embodiment, the character string “in the probability variation mode” is displayed on the variable display H2. In addition, the effect mode includes a variable state mode (chance mode) that can be shifted in either the high probability lottery state or the low probability lottery state. In the chance mode of this embodiment, the character string “in chance mode” is displayed on the variable display H2.

  Next, how to set the production mode will be described with reference to FIG. As shown in FIG. 10, the general CPU 31a, regardless of which effect mode is staying, if a jackpot symbol classified as symbol a is designated as the final stop symbol (that is, the normal probability variable big hit game is If granted), after the big hit game is finished, the probability variation mode is set as the production mode and is shifted. In addition, regardless of the production mode, the general CPU 31a designates a jackpot symbol that is classified as symbol b or symbol c as the final stop symbol (that is, a probability variation big hit with 100 times of shortening). When a game or a non-probable big hit game is awarded), after the big hit game is finished, the chance mode is set as the effect mode and shifted. If the next big hit game is not given by the end of the 100 symbol variation games after the chance mode is set, the general CPU 31a sets and shifts to the normal mode. For this reason, even if the normal mode is set, the probability variation state may be given internally, and even if the chance mode ends, the player can expect the probability variation state to be hidden.

  The overall CPU 31a outputs a mode designation command for designating the effect mode set in the output process executed every predetermined cycle to each of the control boards 32 to 34. Thereby, the production corresponding to the decided production mode is started.

  In addition, the pachinko machine 10 of the present embodiment is configured to execute a notice effect that suggests the possibility that the symbol variation game will be a big hit during the symbol variation game. In this embodiment, the variable display H2 functions as a notice effect execution means, and the notice effect is performed using the variable display H2. And in the pachinko machine 10 of this embodiment, the primary notice effect and the secondary notice effect are set as the kind of the notice effect. In the primary notice effect and the secondary notice effect, the effect is developed in such a way that the character K1 on which the player projects himself looks for the enemy T, and in the secondary notice effect, the background image displayed behind the character K1. A background notice that is executed with different types of effects is executed (see FIG. 13).

Then, the overall CPU 31a determines a primary notice effect pattern that specifies the contents of the effect of the primary notice effect at the start of the symbol variation game.
FIG. 11 is a table associating whether or not the primary notice pattern and the background notice can be executed, and the table is stored in the ROM 31b.

  As shown in FIG. 11, in the pachinko machine 10 of the present embodiment, primary notices A to G are set for the primary notice effect, and the primary notice pattern for identifying the primary notices A to G is the type of variation pattern. To be determined with reference to. Specifically, when there is no primary notice A to F and no primary notice effect ("None" in the figure), the change patterns P4, P6, P8 for the big hit effect and the change pattern for the outlier reach effect during stay in the probability change mode. Selection is possible when P3, P5, and P7 are selected. Further, the jackpot expectation degree of the primary notice is set so that the big hit expectation degree becomes higher in the order of the primary notice A <primary notice B <primary notice C <primary notice D <primary notice E <primary notice F>. Incidentally, the “big hit expectation degree” is calculated based on the ratio that appears when the big hit is won in the big hit lottery and the ratio that appears when the big hit is not won in the big hit lottery. And the higher the appearance rate when winning the jackpot in the jackpot lottery, the higher the chance of hitting the jackpot, compared to the overall appearance rate when winning the jackpot in the jackpot lottery and not winning the jackpot .

  On the other hand, in the pachinko machine 10 of the present embodiment, only the primary notice pattern G is selected when the variation patterns P3 to P8 are selected during the chance mode stay. When the variation pattern P1, P2, P9 is selected while staying in the chance mode or the probability variation mode, the table shown in FIG. 11 is not referred to, and the primary notice, the secondary notice, and the background notice are not executed. Yes.

  The overall CPU 31a, which has selected and determined the primary notice pattern according to the type of mode and the variation pattern during the stay, stores a primary notice designation command for designating the selected primary notice pattern in the RAM 31c, and stores the command in each of the control boards 32-34. Respectively.

  The overall CPU 31a that has determined the primary notice pattern subsequently determines whether or not the background notice is executable. As shown in FIG. 11, the background notice is “executable” only when the user is in the probability change mode and one of “no primary notice” and “primary notices A to D” is selected. It is not decided. On the other hand, when the probability change mode is being stayed and “primary notice E” or “primary notice F” is selected, and when the chance mode is staying, “execution failure” is determined.

  As a result, when determining whether or not the background notice can be executed, the general CPU 31a reads the primary notice designation command set in the RAM 31c while staying in the probability variation mode, and the command designates no primary notice and primary notices A to D. If it is, it will be decided whether or not the background notice can be executed. On the other hand, if the read command is a command designating the primary notice patterns E to G, the overall CPU 31a determines whether to execute the background notice.

  The general CPU 31a that has decided to execute the background notice next selects the effect of the background notice from the background notice pattern distribution table shown in FIG. 12 based on whether the reach formation symbol is an odd number or an even number. Determine the specific background warning pattern. The background notice pattern sorting table (FIG. 12) is stored in the ROM 31b.

  As shown in FIG. 12, four types of background notice patterns J1 to J4 are set as background notice patterns in the present embodiment. Specifically, the background notice pattern J1 is a pattern for specifying the background image E1 (indicated as “no line” in FIG. 13A), while the background notice pattern J2 is the background image E2 (see FIG. In b), the pattern is specified by “vertical line”. Further, the background notice pattern J3 is a pattern that specifies the background image E3 (indicated by “horizontal line” in FIG. 13C), while the background notice pattern J4 is the background image E4 (in FIG. 13D, “ This is a pattern for specifying (indicated by a slanting line from the left to the bottom). These background images E1 to E4 show background images imitating the aura displayed behind the character K1, and the colors of the background images E1 to E4 are different. For example, the background image E1 indicates “white”, the background image E2 indicates “yellow”, the background image E3 indicates “blue”, the background image E4 indicates “red”, and the like.

  And as shown in FIG. 12, background notice pattern J1-J4 is either one according to whether the design designated by the left stop design designation command for decoration is an odd design or an even design. A predetermined number of random values are distributed so that patterns can be selected. In the present embodiment, as described with reference to FIG. 11, the condition for determining whether or not the background notice can be executed is the variation pattern for the big hit effect (variation patterns P4, P6, P8) or the variation pattern for the outlier reach effect (variation pattern). In this case, P3, P5, and P7) are selected. In other words, since the background notice is not executed when the variation pattern for the offending effect is selected, when the background notice pattern is determined, the design designated by the left stop design designation command for the decoration drawing is an odd design. The type of background notice can be determined according to the type of reach formation symbol by simply determining whether the symbol is an even symbol or an even symbol. Specifically, all 335 from 0 to 334 with respect to the background notice patterns J1 to J4 are selected so that any one of the background notice patterns J1 to J4 can be selected when the reach formation symbol is an odd number design. A predetermined number of random numbers for the odd number of symbols are distributed. On the other hand, all the 270 patterns from 0 to 269 with respect to the background notice patterns J1 to J4 are selected so that any one of the background notice patterns J1 to J4 can be selected when the reach formation symbol becomes an even number design. A predetermined number of random numbers for the even number of symbols are distributed.

  As shown in FIG. 12, the background notice pattern distribution table is commonly used in the case of losing reach (except for losing) when winning a big hit. In the background notice pattern distribution table (FIG. 12), random numbers are set so that the ratio of the background notice pattern J1 <background notice pattern J2 <background notice pattern J3 <background notice pattern J4 increases in the order of odd numbers. Sorting. On the other hand, random numbers are distributed so that the proportion selected in the order of background notice pattern J3 <background notice pattern J2 <background notice pattern J1 is higher for even numbers. There is no distribution. Therefore, when winning the jackpot, the background predictive pattern J4 is selected only when the normal probability variable jackpot is determined as the type of jackpot and the odd symbol is determined as the decorative pattern constituting the jackpot symbol combination. Become.

  Then, when the big hit determination is affirmatively determined and when the reach determination is affirmatively determined, the general CPU 31a reads the decorative symbol left stop symbol designation command stored in the RAM 31c, and is designated by the read command. One of the background notice patterns J1 to J4 is determined according to whether the symbol is an "odd number" or "even number". Specifically, the overall CPU 31a determines to select a random number value (0 to 334) for odd symbols when the left stop symbol designation command for decorative symbols designates an odd symbol. On the other hand, the overall CPU 31a determines that the random number value (0 to 269) for the even symbol is selected when the left stop symbol designating command for the decorative symbol specifies the even symbol. Thereafter, the overall CPU 31a again reads the left stop design designation command for decoration drawing, acquires any one random value from the random values determined to be acquired based on the read command, and the random value The background notice pattern is determined based on the above. Then, the overall CPU 31a stores the determined background notice pattern in the RAM 31c.

  By adopting such a distribution mode, in the pachinko machine 10 of this embodiment, as shown in FIG. 14, when an odd symbol is selected as a decorative pattern that forms a jackpot symbol combination, The probability of being selected is obtained by the following calculation formula (2).

Probability that background notice pattern J1 is selected when an odd figure is selected as a decoration that forms a jackpot symbol combination = “probability of winning odd jackpot with odd symbol in one symbol variation game” × “background notice pattern Ratio at which J1 is selected ”(2)
In the pachinko machine 10 of the present embodiment, the background notice pattern is selected based on the reach formation symbol. Further, the probability that the reach effect is executed is higher in the probability variation state (13.000... (%)) Than in the non-probability variation state (10.300... (%)). Thereby, in the pachinko machine 10 of the present embodiment, the probability that the reach effect is performed is higher in the probability variation state than in the non-probability variation state, and the background notice pattern is selected accordingly. Therefore, in the following description, the case where the background notice pattern is selected while staying in the probability variation mode to which the probability variation state is given will be mainly described.

  Accordingly, the probability that the background notice pattern J1 is selected when an odd symbol is selected as the decorative pattern forming the jackpot symbol combination is 1.750 (%) × (70/335) = 0.3656 (%) ) Further, the probability that the background notice pattern J2 is selected when the odd number figure is selected as the decoration forming the jackpot symbol combination is obtained by replacing the above-described calculation formula (2) with the background notice pattern J2, The probability is 0.3917 (%). Similarly, the probability that the background notice pattern J3 is selected when an odd number of symbols is selected as the decoration forming the jackpot symbol combination is 0.4701 (%). In addition, the probability that the background notice pattern J4 is selected when an odd symbol is selected as a decoration that forms a jackpot symbol combination is 0.5223 (%).

  Therefore, the selection probability of the background notice pattern selected when an odd number is selected as the decoration forming the jackpot symbol combination is the background notice pattern J1 <background notice pattern J2 <background notice pattern J3 <background notice pattern J4. It becomes higher in order.

  On the other hand, the probability that the background notice pattern J1 is selected when the even number symbol is selected as the decorative pattern forming the jackpot symbol combination is obtained by replacing the above-described formula (2) with the even number symbol, and the probability Is 0.8209 (%). Similarly, the probability that the background notice pattern J2 is selected when an even number symbol is selected as the decoration forming the jackpot symbol combination is 0.5277 (%). Further, the probability that the background notice pattern J3 is selected when an even number symbol is selected as a decoration that forms a jackpot symbol combination is 0.2345 (%). Note that the background notice pattern J4 is not selected when an even-numbered symbol is selected as a decoration that forms a jackpot symbol combination.

  Therefore, the selection probability of the background notice pattern selected when the even number pattern is selected as the decoration forming the jackpot symbol combination increases in the order of the background notice pattern J3 <background notice pattern J2 <background notice pattern J1. Yes.

On the other hand, the probability that the background notice pattern J1 is selected when an odd symbol is selected as a decorative pattern for forming a symbol combination of outlier reach is obtained by the following calculation formula (3).
Probability that background notice pattern J1 is selected when an odd symbol is selected as a decorative pattern for forming a symbol combination of outlier reach = “probability that an odd symbol is formed in an odd symbol in one symbol variation game” × “ Ratio at which background notice pattern J1 is selected ”(3)
Therefore, the probability that the background notice pattern J1 is selected when an odd symbol is selected as a decorative pattern for forming a symbol combination of outlier reach is 2.900 (%) × (70/335) = 0.6059 ... (%). In addition, the probability that the background notice pattern J2 is selected when an odd number figure is selected as the decorative pattern forming the pattern combination of the outreach reach is obtained by replacing the above-described calculation formula (3) with the background notice pattern J2. The probability is 0.6492 (%). Similarly, the probability that the background notice pattern J3 is selected when an odd symbol is selected as the decorative pattern forming the symbol combination of outlier reach is 0.7791 (%). In addition, the probability that the background notice pattern J4 is selected when the odd symbol is selected as the decorative pattern for forming the symbol combination of outlier reach is 0.8656 (%).

  Therefore, the selection probability of the background notice pattern selected when an odd number figure is selected as the decoration that forms the symbol combination of the outlier reach is the background notice pattern J1 <background notice pattern J2 <background notice pattern J3 <background notice pattern. It becomes higher in order of J4. That is, it is opposite to the selection probability of the background notice pattern that is selected when an even number of symbols is selected as a decoration that forms a jackpot symbol combination.

  On the other hand, the probability that the background notice pattern J1 is selected when the even symbol is selected as the decoration forming the symbol combination of the outreach reach is obtained by replacing the above-described calculation formula (3) with the even symbol, The probability is 3.5086 (%). Similarly, the probability that the background notice pattern J2 is selected when an even number symbol is selected as a decorative pattern that forms a symbol combination of outlier reach is 2.2555 (%). Further, the probability that the background notice pattern J3 is selected when the even number symbol is selected as the decorative pattern forming the symbol combination of the outlier reach is 1.0024... (%). Note that the background notice pattern J4 is not selected when an even-numbered symbol is selected as a decorative drawing that forms a symbol combination of outlier reach.

  In this way, the background notice pattern that is selected when the even symbol is selected as the decorative symbol that forms the symbol combination of outlier reach is selected when the even symbol is selected as the decorative symbol that forms the jackpot symbol combination. As in the case of the background notice pattern, the background notice pattern J3 <the background notice pattern J2 <the background notice pattern J1 increases in this order. However, the selection probability of each background notice pattern is higher at the time of reaching out than at the time of big hit.

  Further, as shown in FIG. 15, the big hit expectation degree (including all big hits) when the background notice pattern J1 is selected is obtained by the following calculation formula. In this calculation formula, the numerator is “the probability that the background notice pattern J1 is selected when an odd symbol is selected as a decorative symbol forming a jackpot symbol combination” + “an even symbol as a decorative symbol forming a jackpot symbol combination. Is the probability that the background notice pattern J1 will be selected. On the other hand, the denominator is “the probability that the background notice pattern J1 will be selected when an odd symbol is selected as a decorative symbol that forms a jackpot symbol combination” + “an even symbol is selected as a decorative symbol that forms a jackpot symbol combination. Probability of selecting background notice pattern J1 when selected "+" Probability of selecting background notice pattern J1 when odd figure is selected as a decoration to form a pattern combination of outlier reach "+" Probability of outlier reach “Probability that the background notice pattern J1 is selected when an even-numbered symbol is selected as a decoration forming the symbol combination”. By dividing this numerator value by the denominator value, Formula (4) is established. Therefore, the big hit expectation degree (including all big hits) when the background notice pattern J1 is selected is (0.3656... (%) + 0.8209... (%)) / (0.3656... (%) +0 ... 8209 (%) + 0.6059 (%) + 3.5086 (%)) × 100 = 22.3844 (%).

  Further, the expected degree of jackpot (including all jackpots) when the background notice pattern J2 is selected can be obtained by replacing the above-described calculation formula (4) with the background notice pattern J2, and the probability thereof is 24.0449. ... (%). Further, the expected degree of jackpot (including all jackpots) when the background notice pattern J3 is selected is 28.3441 (%). Further, the expected degree of jackpot (including all jackpots) when the background notice pattern J4 is selected is 37.6344 (%). This is because when the even number design is selected as the reach formation design, the background advance notice pattern J4 is not selected and the selection probability of the background advance notice pattern is the same when it is out of the big hit. It is almost the same as the big hit expectation when it takes.

  Therefore, in the pachinko machine 10 of the present embodiment, it can be seen that the jackpot expectation is higher in the order of the background notice pattern J1 <background notice pattern J2 <background notice pattern J3 <background notice pattern J4.

  In addition, when the background notice pattern J1 is selected, the jackpot expectation degree (including all jackpots) when reach is reached with an even number of symbols is obtained by a formula obtained by removing the odd symbols from Formula (4). It is done. That is, 0.8209 (%) / (0.8209 (%) + 3.5086 (%)) × 100 = 18.9620 (%). Further, when the background notice pattern J2 is selected and the reach is reached with an even number of symbols, the big hit expectation degree is 18.9620 (%). Further, when the background notice pattern J3 is selected, the big hit expectation degree when the reach is applied with an even number of symbols is 18.9620 (%). Note that the background notice pattern J4 is not selected when an even number symbol is selected as a decorative symbol for forming a jackpot symbol combination or an outlier reach symbol.

  In the pachinko machine 10 of the present embodiment, the background notice pattern distribution table (FIG. 12) is used in common when reaching out of the big hit. At the same time, the selection ratio of the background notice pattern when the even number pattern is shifted reach and the even number pattern is a big hit is set to increase in the order of the background notice pattern J3 <background notice pattern J2 <background notice pattern J1. ing. In addition, the probability that the even number symbol is a big hit is set to be much higher than the probability that the even symbol is a big hit. For this reason, even if any of the background notice patterns J1 to J3 is selected, the big hit expectation degree when the reach is applied with an even number of symbols is substantially the same. Moreover, this value is substantially the same as the big hit expectation degree when the reach is applied with an even number of symbols.

  Note that the jackpot expectation degree when the background notice pattern J1 is selected (the jackpot expectation degree for the normal probability variation jackpot) is obtained by a calculation formula obtained by removing the even symbol elements from the calculation formula (4). That is, 37.6344 (%). This value is substantially the same as the big hit expectation when the reach is applied with an odd number of symbols. On the other hand, when the background notice pattern J1 is selected, the jackpot expectation degree (the jackpot expectation degree for the normal probability variation jackpot and the probability variation jackpot with 100-variable shortening) is the normal probability variation jackpot when the jackpot symbol is formed with even symbols. Since there is a possibility of winning one of the three jackpots, ie, the odd jackpot with 100 times variation or the non-probability jackpot, the probability is the jackpot expectation degree (18.9620 ... (%)). Therefore, when the background notice pattern J1 is selected, it is more likely that the reach symbol is formed with an odd number of symbols than the case where a reach symbol is formed with an even number of symbols. Become. In addition, it is set so that the probability that the even symbol is a big hit is much higher than the probability that the even symbol is a big hit. Therefore, when the background notice based on the background notice pattern J1 is executed, the probability that the odd symbol has a shift reach is higher than the probability that the odd symbol is a big hit and the probability that the odd symbol has a shift reach.

  As a result, when the background notice pattern J1 is selected even when the even number figure is selected as the decorative pattern forming the jackpot symbol combination, the background notice pattern J1 is selected. Therefore, it is possible to give an expectation to winning a promising big hit in the symbol variation game from the next time, not the symbol variation game being executed. In other words, when an odd symbol is selected as a decorative pattern that forms a jackpot symbol combination, if the background notice pattern J1 is selected, an even symbol is selected as a decorative symbol that forms the jackpot symbol combination. Expectation to have a promising big hit is higher than the case. For this reason, it is possible to give an expectation to winning the probable big hit in the symbol variation game being executed. However, in the case of the normal probability variable big hit, since the background notice pattern J1 <background notice pattern J2 <background notice pattern J3 <background notice pattern J4, the most normal predictive variable big hit is expected when the background notice pattern J4 is selected. Can have. In addition, the background notice in the pachinko machine 10 according to the present embodiment is a probability change suggestion that indicates whether or not the big hit expectation is set according to the difference in the production contents, and if the big hit is a positive hit He also plays a role.

  Therefore, in the pachinko machine 10 according to the present embodiment, when the reach is formed with an odd symbol when the jackpot is made while staying in the probability variation mode, the probability that the background notice pattern J4 having a high jackpot expectation level is selected is selected. Is high. On the other hand, when a reach is formed with an even number of symbols in the case of a big hit, the probability that the background notice pattern J1 set with a low big hit expectation degree is selected is high. Thereby, when the background notice based on the background notice pattern J4 set with a high degree of jackpot expectation is executed, it can be expected that the player wins the normal probability big hit. At the same time, when the background notice based on the background notice pattern J1 set with a low jackpot expectation degree is executed, the winning symbol is won in the symbol change game from the next time, not in the currently running symbol change game. You can have expectations.

  In the present embodiment, there is a case where the background notice is executed based on the background notice patterns J1, J2, and J3 set with a low degree of expectation of the big hit, and the big hit is won. Is configured so that it is informed that the promising big hit is won by the promotion effect during the big hit. Therefore, for example, even if a jackpot symbol combination formed with even symbols after the background warning based on the background warning pattern J1 is executed is confirmed and stopped, it will be a promising big hit through the promotion effect during the jackpot. It can be expected.

  Next, the overall CPU 31a selects a secondary notice pattern that specifies the contents of the effect of the secondary notice effect from the secondary notice pattern distribution table shown in FIG. 16 based on the type of the variation pattern and the kind of the primary notice effect. ,decide. The secondary notice pattern distribution table (FIG. 16) is stored in the ROM 31b.

  As shown in FIGS. 16 and 17, six types of secondary notice patterns YA to YF are set as the secondary notice patterns in the present embodiment. Specifically, the secondary notice pattern YA is a pattern that specifies the content that the enemy T does not appear after the character K1 is surprised, while the secondary notice pattern YB is the enemy T after the character K1 is surprised. This is a pattern for specifying the production content in which the appears. The secondary notice pattern YC is a pattern for specifying the content that the enemy T does not appear after the face up of the character K1 is displayed, while the secondary notice pattern YD is a face up in the secondary notice pattern YC. This is a pattern for specifying the content that the enemy T does not appear after the face up of the character K1 is displayed at a different angle. The secondary notice pattern YE is a pattern for specifying the content of the appearance of the enemy T after the face up of the same character K1 as the secondary notice pattern YC is displayed, while the secondary notice pattern YF is In this pattern, the appearance of the enemy T appears after the face up of the same character K1 as the secondary notice pattern YD is displayed.

  In the secondary notice pattern distribution table shown in FIG. 16, any one of the secondary notice patterns YA to YD can be selected for the variation patterns P1 to P9 according to the type of the primary notice pattern. A predetermined number of random number values (all 255 integers from 0 to 254) are assigned.

  Specifically, when the overall CPU 31a determines “no primary notice”, the variation patterns P1 and P2 for the offending effects include “no secondary notice”, “secondary notice pattern YC”, and “secondary notice pattern”. The random number values are distributed so that “YD” can be selected. When the general CPU 31a determines “no primary notice”, the random value is distributed so that only the “second notice pattern YB” is selected in the variation pattern P4 for the big hit effect. Random values are not assigned to the variation patterns P3, P5 to P9 so that the secondary notice patterns YA to YD are not selected.

  On the other hand, when the overall CPU 31a determines the “primary notice pattern A”, random number values are assigned to the fluctuation patterns P3 and P5 for the outlier reach effect so that only the “second notice pattern YA” can be selected. Yes. When the overall CPU 31a determines the “primary notice pattern A”, random number values are distributed so that only the “second notice pattern YB” is selected in the variation pattern P6 for the big hit effect. In addition, random numbers are not assigned to the change patterns P1, P2, P4, P7 to P9 so that the secondary notice patterns YA to YD are not selected.

  Further, when the overall CPU 31a determines “primary notice patterns B to D”, random number values are distributed so that only the “second notice pattern YA” can be selected as the variation patterns P3 and P7 for the outlier reach effect. It has been. Further, when the overall CPU 31a determines “primary notice patterns B to D”, random number values are distributed so that only the “second notice pattern YB” is selected for the variation patterns P6 and P8 for the big hit effect. Yes. In addition, random numbers are not assigned to the variation patterns P1, P2, P4, P5, and P9 so that the secondary notice patterns YA to YD are not selected.

  As described above, after the character K1 is displayed, the secondary notice pattern YB for specifying the content of the appearance of the enemy T can be selected only when the variation pattern for the big hit effect is selected. Therefore, when the enemy T appears on the variable display H2, the big hit is decided. On the contrary, after the character K1 is displayed, the secondary notice pattern YA, YC, YD for specifying the content where the enemy T does not appear is selected as the variation pattern for the outlier effect or the variation pattern for the outlier reach effect. Therefore, if the enemy T does not appear on the variable display H2, the deviation is determined.

  For example, it is assumed that the general CPU 31a selects the primary notice pattern A when a change pattern specifying command for specifying the change pattern P6 is input. In this case, the overall CPU 31a selects and determines the secondary notice pattern YB according to the distribution shown in FIG. In FIG. 16, background notice designation commands for specifying the background notice patterns J1 to J4 are associated with the secondary notice pattern YB. Specifically, in the secondary notice pattern YA, “00H” is used as the lower byte of the background notice designating command for specifying the background notice pattern J1, and “01H” is used as the lower byte of the background notice designating command for specifying the background notice pattern J2. "Is associated. The secondary notice pattern YA corresponds to “02H” as the lower byte of the background notice designation command for specifying the background notice pattern J3 and “03H” as the lower byte of the background notice designation command for specifying the background notice pattern J4. It is attached.

  The secondary notice pattern YB corresponds to “04H” as the lower byte of the background notice designation command for specifying the background notice pattern J1 and “05H” as the lower byte of the background notice designation command for specifying the background notice pattern J2. It is attached. Further, in the secondary notice pattern YB, “06H” is used as the lower byte of the background notice designating command for specifying the background notice pattern J3, and “07H” is used as the lower byte of the background notice designating command for specifying the background notice pattern J4. It is associated.

  Then, the general CPU 31a reads the background notice pattern stored in the RAM 31c in order to identify the background notice designation command, and identifies the background notice designation command corresponding to the background notice pattern. The general CPU 31a that has identified the background notice designation command outputs the command to each of the control boards 32-34.

  On the other hand, as shown in FIG. 16, in the secondary notice pattern YC, all the same value “20H” is set as the lower byte of the background notice designation command for specifying the background notice patterns J1 to J4. In the secondary notice pattern YD, the same value “21H” is set as the lower byte of the background notice designation command that specifies the background notice patterns J1 to J4. Therefore, when the secondary notice patterns YC and YD are selected, the same value is set in the lower byte of the background notice designation command, and the background notice patterns J1 to J4 cannot be specified. It will not be executed.

  FIG. 17 shows a secondary notice pattern distribution table during stay in the chance mode. The table shown in FIG. 17 is stored in the ROM 31b, and random numbers (from 0 to 254) are selected so that any one of the secondary notice patterns YA to YF can be selected for the variation patterns P1 to P9. A total number of 255 integers) is distributed by a predetermined number. Specifically, random values are assigned to the variation patterns P1 and P2 for the offending effect so that “no secondary notice pattern”, “secondary notice pattern YC”, and “secondary notice pattern YD” can be selected. It has been. Further, random number values are distributed so that “secondary notice pattern YE” and “secondary notice pattern YF” can be selected in the variation pattern P4 for the big hit effect. Random values are not assigned to the variation patterns P3, P5 to P9 so that the secondary notice patterns YA to YD are not selected.

  However, as shown in FIG. 17, when the secondary advance notice pattern is selected during the stay in the chance mode, the background advance notice patterns J1 to J4 are not referred to. Therefore, the overall CPU 31a selects only one of the secondary notice patterns YA to YF according to the input change pattern designation command while staying in the chance mode, and does not execute the background notice.

  In the present embodiment, the overall CPU 31a that determines the decoration that forms the jackpot symbol combination serves as the jackpot symbol determination means. The overall CPU 31a that determines the reach formation symbol serves as the reach formation symbol determination means. Further, the overall CPU 31a for determining the background notice pattern serves as the notice pattern determining means.

  Next, the control contents executed by the display control board 32 (sub CPU 32a) according to the effect control program will be described. In the present embodiment, the sub CPU 32a serves as an effect control unit.

  When the sub CPU 32a of the display control board 32 inputs the variation pattern designation command, the variable display H2 is selected so that the effect content corresponding to the variation pattern instructed by the command is selected and the symbol variation game is executed with the effect content. Controls the display content of. At this time, the sub CPU 32a generates display data for displaying an image in accordance with the effect content using the image data in the ROM 32b based on the selected effect content.

  Then, the sub CPU 32a measures the elapsed time from the start of the game with the start of the symbol variation game, and displays an image displayed on the variable display H2 based on the measured time and display data for a predetermined control cycle. Switch every time (for example, every 2 ms). Then, when the sub CPU 32a inputs a symbol stop command during the symbol variation game, the display content of the variable display H2 is displayed on the variable display H2 so that the symbol designated by the decorative symbol stop symbol designation command is displayed on the variable display H2. To end the symbol variation game.

  Further, when the opening command is input, the sub CPU 32a controls the display content of the variable display H2 so as to execute the opening effect. Further, when the sub CPU 32a inputs a round start command, the sub CPU 32a controls the display content of the variable display H2 so as to execute a round effect. Further, when the sub CPU 32a inputs the round end command, the sub CPU 32a controls the display content of the variable display H2 so as to execute the interval effect. Further, when the ending command is input, the sub CPU 32a controls the display content of the variable display H2 so as to execute the ending effect. Thereby, in the variable display H2, an opening effect, a round effect, an interval effect, and an ending effect are each performed. And in the pachinko machine 10 of this embodiment, it is comprised so that a promotion effect during a big hit may be performed in the predetermined round game in a big hit game. For this reason, the sub CPU 32a controls the display content of the variable display H2 so as to cause the jackpot promotion effect to be performed when the effect content instructed by the effect instruction command for the round effect is the jackpot promotion effect. When the sub CPU 32a inputs a mode designation command for designating the production mode, the sub CPU 32a controls the display content of the variable display H2 so as to change the background image in accordance with the production mode designated by the mode designation command.

  When the sub CPU 32a executes the notice effect while staying in the probability variation mode, after the start of the symbol variation game, and before forming the reach with the symbol instructed by the stop symbol designation command for decoration, The display content of the variable display H2 is controlled so that the secondary notice effect is executed with the contents designated by the input secondary notice designation command. Next, the sub CPU 32a controls the display contents of the variable display H2 so that the background notice is executed with the contents designated by the input background notice designation command. Thereafter, the sub CPU 32a executes the secondary notice effect after executing the secondary notice effect and before executing the reach, so that the primary notice effect is executed with the contents designated by the inputted primary notice designation command. The display content of H2 is controlled. Then, the sub CPU 32a forms a reach with the decoration designated by the decorative symbol stop symbol designation command to execute the reach effect, and when the symbol stop command is input, the sub CPU 32a is instructed by the decorative symbol stop symbol designation command. The display content of the variable display H2 is controlled so that the fixed display is displayed on the variable display H2 in a fixed stop state, and the symbol variation game is ended.

  Next, the flow of the game in the variable display H2 when the primary notice, the secondary notice, and the background notice are executed will be described with reference to FIGS. In the description of FIGS. 18 (a) to 18 (f), in accordance with the winning of the normal probability variation big hit, the variation pattern P8 for the big hit effect, the primary notice pattern B, the secondary notice pattern YB, and the background notice pattern. A description will be given assuming that J4 is selected. In addition, the description will be made assuming that [9] is selected as a decorative drawing for forming a jackpot symbol combination.

  When the symbol variation game starts while staying in the probability variation mode, the symbol display mode is displayed on the variable display H2 at the lower right of the variable display H2. Then, after a lapse of a predetermined time from the start of the change of the symbol, the character K1 searching for the enemy is displayed as an image in accordance with the content set in the secondary notice pattern YB (FIG. 18 (a)). Thereafter, in the variable display H2, before the reach symbol is formed, the secondary notice effect is executed with the contents that the character K1 is surprised as the pre-reach notice according to the contents set in the secondary notice pattern YB. At this time, the variable display H2 displays the background image E4 behind the character K1 in accordance with the content defined in the background notice pattern J4 (FIG. 18B). As a result, even before the reach symbol is displayed, the player has an expectation that a reach is formed with an odd symbol due to the display of the background image E4, resulting in a probable big hit. . Thereafter, in the variable display H2, the primary notice is executed in accordance with the contents defined in the primary notice pattern B before the reach symbol is formed (FIG. 18 (c)). In the primary notice pattern B, the contents of communication between the character K1 and the character K2 are set.

  Subsequently, in the variable display H2, after a predetermined time elapses, the communication image by the characters K1 and K2 disappears from the screen, and the reach symbol combination indicated by [9 ↓ 9] is derived at the right end of the variable display H2. As a result, the reach effect is executed (FIG. 18D). Then, after a predetermined time has elapsed since the start of the reach effect, the enemy T appears based on the selection of the secondary notice pattern YB (FIG. 18D). In the present embodiment, since the secondary advance notice pattern in which the enemy T appears is associated only with the variation pattern for the big hit effect, the player recognizes that the enemy T appears as a big hit (FIG. 18 ( d)). Accordingly, the reach effect executed in FIG. 18D is an effect that suggests whether or not the enemy T appears. In addition, since the reach formation symbol at this time is an odd symbol, the player recognizes that it is usually a probable big hit. Thereafter, on the variable display H2, as the variation time set in the variation pattern P8 elapses, the jackpot symbol combination [999] is enlarged and displayed on the screen. When the symbol stop command is input, 999] is displayed as a fixed stop, and the symbol variation game ends (FIG. 18 (e)). After that, the big hit game is started, and the variable display device H2 displays a probability change notification image of “Congratulations on the probability change” at the start of the big hit game (FIG. 18 (f)), and the player recognizes that the player has usually won the probability change big hit. Will do.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) When the central CPU 31a determines that the jackpot determination is affirmative while staying in the probability variation mode, the background warning pattern in which the background prediction performed when the reach formation symbol is formed with an odd symbol is set to have a high jackpot expectation degree. The reach formation pattern and the background notice pattern are determined to be performed at a high rate based on the above. On the other hand, the general CPU 31a, when the big hit determination is affirmed while staying in the probability variation mode, the background notice pattern that is set when the reach formation symbol is formed with an even number of symbols is a background notice pattern in which the big hit expectation degree is set low The reach formation pattern and the background notice pattern are determined to be performed at a high rate based on the above. In this way, by determining the content of the background notice in consideration of the type of reach formation symbol, when the reach is formed by the odd symbol, it has an expectation that it has won the probable big hit. Can be made.

  (2) Even if the reach is lost after reaching the reach, if the reach is formed by odd number of symbols, it is expected that the winning symbol will be won until the symbol is confirmed and stopped. Can be given.

  (3) By executing the background notice before the reach is formed, it is possible to guess whether or not a certain change state is given based on the type of the background notice when the contents of the notice effect are visually recognized.

  (4) When a player wins a jackpot while the probability variation state is given, the player pays the most attention to whether or not the jackpot is a probability variation jackpot. Therefore, the background notice executed during the stay in the probability change mode can be entertained by determining the background notice pattern based on the reach formation pattern only during the stay in the probability change mode. In addition, the control of determining the type of background notice based on the reach formation symbol is regulated so that it does not appear frequently in any gaming state, so that the execution mode of the production can have a sharpness. it can.

  (5) By setting the expectation to the probability variation state to be different depending on the type of symbol, it is possible to make the player interested in which symbol the reach is formed on.

  (6) Since the background notice has contents that can be used in common regardless of which of the secondary notice patterns YA and YB is selected, the background notice is available regardless of which of the secondary notice patterns is selected. The notice can be executed without a sense of incongruity.

  (7) In the case of a promising big hit, the background notice is executed based on the background notice pattern J4. On the other hand, in the case of losing, the background notice is executed based on the background notice pattern J1. The ratio is set high. Thus, it is possible to notify the player whether or not the player can have an expectation for the probable big hit just by visually recognizing the content of the background notice.

  (8) The background notice pattern distribution table (FIG. 12) is used in common when reaching out of the big win. Further, the selection probability of the background notice pattern when the even number pattern is shifted reach and when the even number pattern is a big hit is set to increase in the order of the background notice pattern J3 <background notice pattern J2 <background notice pattern J1. In addition, the probability of a shift reach in the even symbol is set higher than the probability of a big hit in the even symbol. As a result, even if any of the background notice patterns J1 to J3 is selected, when reach is achieved with an even number of symbols, the pattern is almost the same without making a difference in the degree of big hit expectation depending on the effect of the background notice. It is possible to give an expectation to winning a promising big hit in the symbol variation game after the next with a probability of.

  (9) When the background notice pattern J1 to J3 is selected when the even number design is selected as the reach formation design, the probability variation big hit expectation degree of the background notice pattern J1 to J3 is set to be substantially the same value. Thus, when an even number symbol is selected as the reach formation symbol, the big hit can be expected based only on the big hit expectation degree set in the background notice pattern. That is, when an even number symbol is selected as the reach formation symbol, it can be expected that the notice effect is executed based on the background notice pattern J3 set with a high degree of jackpot expectation.

  (10) The background notice is executed based on the background notice pattern J1 set with a low degree of expectation of the big hit, and there is a case where the big hit is won, but when the promising big hit is won, the promotion effect during the big hit is executed. Configured to be. As a result, even if the jackpot symbol combination formed with even symbols after the background trailer based on the background trailer pattern J1 is executed is confirmed and stopped, it will be a promising big hit through the promotion effect during the jackpot. Can be expected.

  (11) Depending on which jackpot is won during stay in the probability variation mode, it is determined whether the probability variation mode is continued or the mode is shifted to the chance mode. And, when staying in the probability variation mode, if the probability variation big hit with change 100 times or the non-probability big hit is won, the mode is shifted to the chance mode. Even in such a case, depending on the type of background notice executed based on winning the jackpot while staying in the probability variation mode, expectation for whether or not the probability variation state is given after the transition to the chance mode. You can have it. In such a case, it is possible to give the highest expectation when the notice effect is executed based on the background notice pattern J3 set with a high expectation degree of jackpot.

In addition, you may change the said embodiment as follows.
In the embodiment, a re-lottery effect may be executed in place of the jackpot promotion effect. Further, both the jackpot promotion effect and the re-lottery effect may be set, and it may be determined which effect is executed by the lottery. By the way, the re-lottery effect is a temporary jackpot symbol (a symbol combination by a decorative symbol) that is temporarily stopped during a symbol variation game, and then finally a big hit symbol (a symbol symbol combination by a decorative symbol) that is confirmed and stopped. It is performed in the effect mode to derive. Then, when the re-lottery effect is executed, the reach effect is executed by the decorative drawing that forms the temporary jackpot symbol before deriving the temporary jackpot symbol. In this case, the overall CPU 31a determines the effect of the background notice based on the decoration drawing that forms the temporary jackpot symbol.

  ○ The type of background notice may be determined based on the reach formation symbol even during the chance mode stay with the certainty state. In such a case, even during the chance mode stay, it can be expected to win a big hit based on the type of background notice.

  ○ In the embodiment, as shown in FIG. 6, the probability change big hit with 100 times variation and the non-probability big hit are set as the same table, and the symbol combination of the big hit is determined at the same ratio. A table for probability variation jackpots and a table for non-probability variation jackpots may be set separately.

  In the embodiment, in the secondary notice pattern distribution table shown in FIG. 16, the enemy T may appear in the secondary notice pattern YA. Further, the enemy T may not appear in the secondary notice pattern YA, but the secondary notice pattern YB may be selected even when the variation pattern for the loss reach effect is selected. good. In addition, both secondary notice patterns are selected so that either the secondary notice pattern YA or the secondary notice pattern YB can be selected for the fluctuation pattern for the big hit effect and the change pattern for the outlier reach effect. Random values may be distributed. By setting in this way, it is possible to make it difficult for the player to know whether or not the probability variation state is given from the contents of the production of the secondary notice effect, and that the probability variation state is given to the player. Expectation can be given to them.

  ○ In the embodiment, when a big hit is won, when a specific odd symbol (for example, “9”) is selected from among odd symbols, the selection rate of the background notice pattern J4 is selected when another odd symbol is selected. It may be set so as to be much higher than the rate, and it may be set so that the degree of expectation held for winning a promising big hit among odd symbols is different.

  ○ In the embodiment, a specific odd symbol (for example, “9”) among odd symbols is used as a symbol that definitely indicates that the normal probability variable big win is won, and the remaining odd symbols are changed to the normal probability variable big hit or 100 times. It may be a symbol that suggests that you have won one of the short-term probable big hits.

  ○ In the embodiment, while the jackpot symbol combination with odd number of symbols is the probability change confirmed big hit symbol, the jackpot symbol combination with even number of symbols is the probability variation non-deterministic jackpot symbol, but is not limited to such classification, for example, , “1” to “5” may be used as the jackpot symbol for the probability variation confirmation, and “6” to “9” may be the jackpot symbol for the probability variation non-determination.

In the embodiment, the background notice may be executed after the symbols in the left column are stopped.
In the embodiment, the background notice may be executed after the reach formation.

In the embodiment, the background notice may be executed before the reach formation, and the temporary notice may be executed after the reach formation.
○ In the embodiment, the content of the background notice is determined based on the reach formation symbol at the time of reach that is different from the time of winning the big hit, but the content of the background notice is determined based on the reach formation symbol only when the big hit is won. You may do it.

  In the embodiment, the notice pattern is selected after the symbol combination by the decorative drawing is determined. However, the symbol combination by the decorative drawing may be determined after the notice pattern is determined.

  In the embodiment, after determining the primary notice pattern, it may be determined whether to execute the background notice, and then the contents of the secondary notice pattern may be decided before determining the contents of the background notice.

  In the embodiment, the selection ratio of the background notice pattern may be changed as appropriate. Further, instead of the distribution shown in FIG. 12, the selection ratio of the background notice pattern may be changed at the time of reaching out of the big hit. In this case, the background notice pattern J4 may be more easily selected at the time of big hit than at the time of outlier reach, and the background notice pattern J1 may be easily selected at the time of outlier reach than at the time of big hit.

  In the embodiment, the same number of random number values may be distributed between the odd number symbol and the even number symbol as the random number value when selecting the background notice pattern. Further, the same random number value may be used for odd and even symbols. By doing in this way, the process which selects a random number value separately by whether the decoration designated with the left stop design designation | designated command for decorations is an odd number design or an even number design can be reduced. Moreover, you may distribute a random value for every symbol so that a background notice pattern may be selected for each symbol of [1]-[9].

  In the embodiment, the expectation level for jackpot is suggested by the content of the background notice executed by the variable display H2, but a notice effect instead of the background notice may be executed by the decoration lamp 16. In this case, the decorative lamp 16 is controlled so that the lamp control board 33 receives the instruction from the general CPU 31a and executes the display effect.

  ○ In the embodiment, the types of jackpot games are not limited to the three types of normal jackpots, odd-change jackpots with 100-speed variation, and non-probability jackpots, and the number of rounds, number of winning balls, A plurality of types of big hit games with different numbers of symbol variation games to which presence / absence or a variable state is given may be set.

  In the embodiment, the effect display device 20 may be changed to a display device that displays a graphic image by light emission of a light emitter, for example, a 7-segment LED type or a dot matrix type display device.

  In the embodiment, the overall control board 31 may be processed by the display control board 32. Alternatively, a control board in which the overall control board 31, the lamp control board 33, and the sound control board 34 are integrated may be mounted so that the overall control board 31 is processed by the control board.

  In the embodiment, the pachinko machine 10 using the special symbol and the decorative symbol is embodied. However, the pachinko machine using only the special symbol may be embodied. Further, it may be embodied in a pachinko gaming machine using a plurality of special symbols.
