Description

  The present invention relates to a gaming machine to which a probability variation state is provided in which the winning probability of jackpot is changed from a normal probability that is a low probability to a high probability.

  Conventionally, some pachinko machines that are a type of gaming machine have a probability variation function that shifts the lottery probability state of the big hit lottery to the high probability lottery state after the big hit game that opens the big prize opening. . If the lottery probability state of the big hit lottery is a high probability lottery state (probability variation state), it is easy to win a big hit in the big hit lottery, which is advantageous to the player. Usually, if a player wins a big hit in the big hit lottery and obtains the big hit game, the player wants to be given a high probability lottery state as the gaming state after the big hit game ends. For this reason, when it turns out that it will not be in a high-probability lottery state after the jackpot game ends, but may be in a low-probability lottery state, there is a possibility that the player's interest will be reduced. Therefore, by making it difficult for the player to recognize whether the high-probability lottery state is given or the low-probability lottery state is given, it is possible to guess whether the lottery probability state is a high-probability lottery state. There was something that improved interest (for example, Patent Document 1).

  In Patent Document 1, the lottery probability state after the end of the jackpot game is changed to a high probability lottery state, and the jackpot is opened twice during the display effect during the jackpot game (hereinafter referred to as “probability 2”). "Round jackpot game"). Further, in Patent Document 1, a display effect that is the same mode is developed as if it is during a probabilistic 2-round jackpot game, and the winning opening is opened in the same manner as that of a probable 2-round jackpot game during the display effect. It is provided with “small hit 1” (hereinafter referred to as “small hit game”) that is (opened twice). And after the end of the small hit game, the lottery probability state at the time of winning is maintained.

  For this reason, in Patent Document 1, when the winning prize opening is opened twice during the display effect that is executed in response to the winning of the probability variation 2 round jackpot game and the bonus game, the probability variation 2 round jackpot game and the bonus game are played. It is difficult for the player to recognize which winning of the game is being triggered. In this way, when the big winning opening is opened twice, if the lottery probability state is the low probability lottery state, when the probability variation 2 round big hit game is internally triggered, the lottery probability state becomes the high probability lottery state, In particular, when a small hit game is triggered, the lottery probability state at the time of winning is maintained and the lottery state is in a low probability lottery state. Therefore, it is difficult for the player to recognize whether the game is a probability-changing two-round big hit game or a small hit game, and thus it is difficult to recognize whether the lottery probability state is in the high probability lottery state after the big winning opening is opened. ing.

  By the way, such a gaming machine generally recognizes that when a jackpot game (15R jackpot) that can recognize that a probability change state is given is given, a probability change state is given after the jackpot game ends. The probability change mode that can be set is set. On the other hand, when a probabilistic two-round big hit game or a small hit game is awarded, after the big hit game is completed, the possibility that the probabilistic state has been granted is suggested and whether or not the probable state has been given cannot be recognized. The suggestion mode is set.

JP 2006-1116016 A

  However, since the same probability change suggestion mode is set, there is a possibility that the user will get bored if the probability change mode is set many times. In addition, regardless of the content of the game effect in the probability variation mode, setting the same probability variation suggestion mode will end the probability variation mode, and it may give the impression that there is a possibility that the probability variation state has ended. There was also a possibility that interest would fall.

  The present invention has been made by paying attention to such problems existing in the prior art, and its purpose is to draw attention to the game effect in the probability variation mode and to suppress the player's tiredness in the probability variation suggestion mode. An object of the present invention is to provide a gaming machine that can be used.

  In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that an execution of an effect of displaying a symbol variation game that is performed by varying a plurality of types of symbols when a winning ball is detected by a winning detection means. Means for displaying a predetermined jackpot display result in the symbol variation game, whether the symbol variation game is a jackpot in a gaming machine to which a bonus game in which the special winning means is opened and closed is given Jackpot determining means for determining whether or not, if the determination result of the jackpot determining means is affirmative, determining the type of jackpot game to be awarded after the end of the symbol variation game, and jackpot game granting means for granting the determined jackpot game, If the determination result of the jackpot determination means is affirmative, whether or not to give a probability change state to change the winning probability of the jackpot determination to a higher probability than the normal state after the end of the jackpot game If the determination result is affirmative, a probability change determination means for giving a probability change state after the jackpot game ends, and a mode setting means for setting a probability change mode indicating to the player that the probability change state is in the probability change state; When the probability change mode is set by the mode setting means, the content control means for determining the content of the game effect related to the symbol variation game according to the set probability change mode, and executing the game effect with the determined content; There is a possibility that the jackpot game granting means is given a probability change state regardless of whether the determination result of the probability change determination means is affirmative or negative. While a normal jackpot game suggesting that It is configured to be able to give a game, and when the normal big hit game is given during the probability change mode, the mode setting means may be given a probability change state after the normal big hit game is ended. Probability change suggestion mode is set, and the effect control means is a special game among a plurality of types of game effects by the effect operation means during the operation effective period set during the probability change mode or the probability change big hit game. When the probability change suggestion mode is set after the effect is selected, the gist is that the game effect related to the selected special game effect can be executed during the probability change suggestion mode.

  According to a second aspect of the present invention, in the first aspect of the present invention, the effect control means is configured so that a plurality of types of the effect control means are operated by the effect operation means during the operation effective period set during the probability change mode or the probability change big hit game. When a special game effect is selected from the game effects, the game effect related to the selected special game effect can be executed as long as either the probability change mode or the probability change suggestion mode is set continuously. It is summarized as follows.

  The invention described in claim 3 is the operation set in the probability variation mode or the probability variation big hit game when the probability variation big hit game is given during the probability variation suggestion mode in the invention according to the first or second aspect. The gist is that the types of game effects that can be selected during the effective period increase.

  According to the present invention, it is possible to pay attention to the game effect in the probability variation mode and to suppress the player's tiredness during the probability variation suggestion mode.

Hereinafter, an embodiment in which the present invention is embodied in a pachinko gaming machine (hereinafter referred to as a “pachinko machine”) which is a kind of gaming machine will be described with reference to FIGS.
In FIG. 1, a first special figure display H0 as a 7 segment type display means and a second special figure display H1 as a 7 segment type display means are adjacent to the lower left of the game board YB. . In the center of the game board YB, a variable display H2 is disposed as a liquid crystal display type display means. In the first special symbol display device H0 and the second special graphic display device H1, a symbol variation game is performed in which a plurality of types of symbols are varied and displayed. In the variable display H2, a display effect related to the symbol variation game performed in the first special figure display H0 or the second special figure display H1 is performed. Specifically, the variable display H2 performs a display effect based on a fluctuating image (or image display), and changes a plurality of types of symbols in a plurality of columns to display a symbol combination game (hereinafter referred to as a symbol). May be shown as a combination game).

  In the symbol variation game, the first special symbol display H0 or the second special symbol display H1 changes a plurality of types of special symbols (hereinafter, may be referred to as “special symbols”) in a single column. Is displayed. This special figure is a notification pattern indicating the result of an internal lottery such as whether or not a big hit. Hereinafter, the symbol variation game performed on the first special symbol display device H0 is referred to as “first variation game”, and the symbol variation game performed on the second special symbol display device H1 is referred to as “second variation game”. There is. On the other hand, in the display effect related to the symbol variation game, the variable display H2 varies a plurality of types of decorative symbols (hereinafter sometimes referred to as “decorative diagrams”) in a plurality of columns (in this embodiment, three columns). Display a decorative drawing for each column. This decorative drawing is a design for production used for diversifying display production.

  Then, on the first special figure display H0 or the second special figure display H1, the variation display of the symbol is started simultaneously with the start of the symbol variation game, and the special diagram is confirmed and stopped simultaneously with the end of the game. In addition, the variable display H2 starts the decorative display of the decorative drawing at the same time as the start of the symbol changing game, and the decorative drawing is temporarily stopped and displayed in a swinging and changing state before the end of the game. The decoration drawing is displayed in a fixed stop state. “Fluctuation display” is a state in which the type of the symbol displayed in the display area defined in the indicator that displays the symbol is changing. “Temporary display” means that the symbol is shaken in the display area. This is a state displayed in a fluctuating state. The “definite stop display” is a state in which the symbols are fixed and stopped in the display area. In the first special figure display H0 and the variable display H2, display effects relating to the symbol variation game and the symbol variation game are started at the same time, and are simultaneously ended (that is, the special diagram and the decoration drawing are confirmed and stopped at the same time). ). Similarly, in the second special symbol display H1 and the variable display H2, the display effects relating to the symbol variation game and the symbol variation game are started at the same time, and are simultaneously ended (that is, the special symbol and the decoration drawing are simultaneously displayed in a fixed stop state. ) On the other hand, the first special figure display H0 and the second special figure display H1 do not play the symbol variation game in parallel. That is, only one of the first variation game and the second variation game is executed.

  In the present embodiment, the first special figure display H0 and the second special figure display H1 include one special figure corresponding to the lottery result of the big hit lottery from a plurality of special figures (101 kinds in the present embodiment). A figure is selected, and the selected special figure is individually displayed in a fixed stop state when the symbol variation game ends. The 101 types of special symbols are classified into 100 types of jackpot symbols (corresponding to the jackpot display result) that can recognize jackpots, and one type of outlier symbol that can recognize a jackpot. When the jackpot symbol is displayed, the player is awarded a jackpot game. The jackpot game of this embodiment will be described in detail later.

  In the present embodiment, the variable display H2 includes 8 [1], [2], [3], [4], [5], [6], [7], and [8] for each column. Numbers of types are displayed as decorative drawings. In the present embodiment, the variable display H2 is configured with a larger display area than the first special figure display H0 and the second special figure display H1, and the decorative drawing is far more than the special figure. Is displayed larger. For this reason, the player can recognize the big hit or miss from the symbol combination stopped and displayed on the variable display H2. When the symbols of all the columns that are stopped and displayed on the variable display H2 are of the same type, the jackpot to which the jackpot game is given can be recognized from the symbol combination ([222] [777] or the like). The symbol combination that can recognize this jackpot is a jackpot symbol combination (big hit display result) by a decorative drawing. When the big hit symbol combination is displayed in a fixed stop state, the player is given a big hit game after the end of the symbol variation game. On the other hand, in the case where the symbols of all columns displayed on the variable display H2 are stopped and displayed, or when the symbols of one column are different from the symbols of the other two columns, in principle, the symbol combination ( [123] [122] [767] etc.) can be recognized. The symbol combination which can recognize this deviation becomes a symbol combination (outlier display result) of the deviation by the decorative drawing. It should be noted that if a predetermined symbol combination ([565] in the present embodiment) is displayed among the off symbol combinations, it can be recognized that a big hit game is awarded. This symbol combination is a symbol combination of probability change suggesting that there is a possibility that a probability variation state in which the probability of jackpot determination is low probability to high probability is given.

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

  The variable display H2 displays symbol combinations according to the display results of the first special figure display H0 and the second special figure display H1. More specifically, a special combination displayed on the first special graphic display H0 or the second special graphic display H1 and a combination of symbols displayed on the variable display H2 are associated with each other. When the process is completed, the symbol combination of the special figure and the decorative drawing is displayed correspondingly in a fixed stop state. For example, when the big hit symbol is confirmed and stopped on the first special symbol display H0 or the second special symbol display H1, the symbol combination of the big hit or the symbol combination indicating the probability change is also confirmed and stopped on the variable indicator H2. It has come to be. Further, when the off symbol is stopped and displayed on the first special symbol display H0 or the second special symbol display area H1, the off symbol combination is also displayed on the variable indicator H2 in a fixed stop manner. . In addition, the symbol combination of the decorative drawing with respect to the special drawing is not necessarily one-to-one, and the symbol combination with one decorative drawing is selected from among the symbol combinations with a plurality of decorative drawings for one special drawing. Yes. As described above, in the variable display H2 of the present embodiment, the display effects related to the first and second variable games (the symbol variable game in which the three symbol combinations are displayed in a variable manner to display a combination of symbols). Is to be done.

  In addition, a normal symbol display H10 composed of two LEDs is disposed at the lower left of the game board YB and below the first special figure display H0 and the second special figure display H1. In this normal symbol display H10, a symbol combination game (hereinafter referred to as “general symbol game”) that derives one common symbol by varying a plurality of types of ordinary symbols (hereinafter sometimes referred to as “common symbol”). Is sometimes displayed). In this embodiment, there are three types of ordinary diagrams in the light emission mode of two LEDs. Specifically, the two LEDs are lit together, only the right LED is lit, only the left LED is lit. Shows multiple types of common maps. In the following, for convenience of explanation, the general map shown when both LEDs are turned on is called “0”, and the general map shown when only the right LED is turned on is called “1”. The usual figure shown by turning on only the LED is the ordinary figure “2”.

  The player can recognize a normal hit or deviation from a symbol combination (display result derived in the general game) finally displayed in the general game. When the normal symbol displayed on the normal symbol display H10 is “1” or “2”, the normal hit can be recognized. The usual figure which can recognize this normal hit becomes the display result of the normal hit. When the normal hit display result is displayed, the normal hit game is given to the player. In addition, when the common figure displayed on the normal symbol display H10 is “0”, a deviation from the usual figure can be recognized. The usual figure which can recognize this detachment becomes a display result of detachment.

  Further, as shown in FIG. 1, a first start winning opening 25 having a first starting entrance into which a game ball can always enter is disposed below the variable display H2.

  In addition, the pachinko machine 10 according to the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function as a special gaming state advantageous to the player after the big hit game. The probability change function is a low probability (normal state) of the jackpot lottery probability (winning probability) after the jackpot game ends, provided that the type of jackpot symbol (special figure) that is confirmed and stopped is a predetermined probability variation symbol. This is a function that gives a probability variation state (probability variation state) that varies from a certain normal probability (4/1439 in the present embodiment) to a high probability (36/1439 in the present embodiment). In this embodiment, a jackpot to which a probability variation state is given after the jackpot game ends is a probability variation jackpot, and a jackpot to which a probability variation state is not imparted is a non-probability variation jackpot.

  In addition, the pachinko machine 10 according to the present embodiment has a time-shortening function that gives a state of varying time shortening (hereinafter referred to as “short-time”) as a special game state advantageous to the player after the big hit game. When the short-time state is given, the fluctuation time of the ordinary game for deriving the lottery result of whether or not to open and close the opening / closing blade 26 is shortened, and the normal hit probability of the ordinary game is increased from the normal probability to the high probability Fluctuating entrance rate improvement state is given as a privilege. In this improved entrance rate, the open / close blade 26 opens and closes in an operation pattern different from that in the normal state (non-short-time state) when winning in the normal game. In other words, when the normal game is won in the normal state, the opening / closing blade 26 is opened once, and the open state is maintained until 300 ms elapses after the opening. On the other hand, in the case of winning the normal game when the entrance rate is improved, the opening / closing blade 26 is opened three times and the opened state is maintained until 1460 ms elapses after opening in one opening. It has become. In other words, the opening / closing blade 26 is set so that when the entrance rate improvement state is given, the total opening time is longer than the state where the normal state is given, and the player operates favorably for the player. Yes. In addition, the short time state (entrance rate improvement state) of this embodiment is granted depending on the type of jackpot game and the game state in which the symbol variation game that becomes the jackpot game is played, and to what time It is decided to be done.

Next, the jackpot game defined in the pachinko machine 10 of this embodiment will be described in detail based on FIG.
The big hit game is started after the big hit symbol (and the big hit symbol combination) is stopped and displayed on the respective displays H0 to H2 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 effect, the round game in which the upper prize opening 28 (or lower university prize opening 29) is opened is performed a plurality of times with a predetermined number of rounds as a predetermined upper limit (16 rounds or 4 rounds in this embodiment). . One round game is until the upper university prize opening door 28a or the lower university prize opening door 29a is opened and closed a predetermined number of times. It is released until a specified number (game play upper limit number) of game balls wins or until a specified time (round game time) elapses. In round games, round effects are performed. Then, an ending effect indicating the end of the jackpot game is performed, and the jackpot game is ended.

  In the pachinko machine 10 according to the present embodiment, when the big hit lottery is won, one big hit game is determined from the four types of big hit games shown in FIG. 3, and the determined big hit game is given. It has become. Of the four types of jackpot games, which jackpot game is awarded is determined in accordance with the type of special symbol (big jackpot symbol) that is determined when the jackpot lottery is won. In this embodiment, the 100 special symbol jackpot symbols displayed on the first special symbol display H0 are classified into four groups of symbol A, symbol B, symbol C and symbol D as shown in FIG. ing.

  That is, 35 types of big hit symbols among the big hit symbols displayed on the first special symbol display H0 are distributed to the symbol A. Similarly, 35 types of jackpot symbols among the jackpot symbols displayed on the first special symbol display H0 are allocated to the symbol B. In the symbol C, ten types of jackpot symbols are distributed among the jackpot symbols displayed on the first special symbol display H0. Of the jackpot symbols displayed on the first special symbol display H0, 20 types of jackpot symbols are assigned to the symbol D.

  Further, in the present embodiment, the 100 types of special symbol jackpot symbols displayed on the second special symbol display H1 are classified into four groups of symbol a, symbol c and symbol d as shown in FIG. Yes. 70 kinds of big hit symbols among the big hit symbols displayed on the second special symbol display H1 are distributed to the symbol a. Similarly, 10 types of jackpot symbols among the jackpot symbols displayed on the second special symbol display H1 are distributed to the symbol c. Of the jackpot symbols displayed on the second special symbol display H1, 20 types of jackpot symbols are assigned to the symbol d.

  The jackpot game given when the jackpot symbol classified as symbol A is displayed on the first special symbol display H0, or when the jackpot symbol classified as symbol a is displayed on the second special symbol display H1. Is a “16R special probability variable big hit game” in which the specified number of rounds is set to “16” and a probability change state is given after the big hit game ends. In the 16 round games in the 16R special probability variable big hit game, the upper prize winning door 28a is set to be opened in each round game. In addition, in the 16R special probability variable big hit game, regardless of the game state at the time of winning the big hit lottery, the positive change state is given after the big hit game is finished and the entrance rate improvement state is given until the end of the positive change state. . In FIG. 3, a case where the entrance rate improvement state is given from the time when the probability variation state is given until the next big hit is expressed as “no limit”.

  In addition, in the 16R special probability variable big hit game, the opening time is “10 (seconds)”, the round game time (specified time) of one round game is “25 (seconds)”, and the ending time is “11 (seconds)” "Is set for each. Each round game may be terminated when a maximum number of game balls are entered. Therefore, in the 16R special probability variable big hit game, “25 (seconds)” that is the round game time of one round game is the maximum time. Although not shown in FIG. 3, the interval time between rounds (interval between rounds) in the 16R special probability variable big hit game is set to “2.0 (seconds)”.

  The jackpot game given when the jackpot symbol classified as the symbol B is displayed on the first special chart display H0 has a specified round number set to “16” and the probability change state after the jackpot game ends. Is a “16R normal probability variation big hit game”. In the 16R normal probability variation big hit game, the lower big prize opening door 29a is set to be opened in the round big game. In addition, in the 16R normal probability variable big hit game, regardless of the game state at the time of winning the big hit lottery, the positive change state is given after the big hit game is finished and the entrance rate improvement state is given until the end of the probability change state. .

  In the 16R normal probability variation big hit game, “10 (seconds)” is set as the opening time, and “11 (seconds)” is set as the ending time. In the 16R normal probability variation big hit game, in the first to tenth rounds, “25 (seconds)” is set as the round game time. In the 16R normal probability variation big hit game, the round game time is set to “0.1 (seconds)” in the 11th to 16th rounds. Although not shown in FIG. 3, the interval time between rounds in the 16R normal probability variation big hit game is set to “2.0 (seconds)”.

  The jackpot game given when the jackpot symbol classified as symbol C is displayed on the first special symbol display H0 or when the jackpot symbol classified as symbol c is displayed on the second special symbol display H1. Is a “4R probability variable big hit game” in which the specified number of rounds is set to “4” and a probability change state is given after the big hit game ends. In the four round games in the 4R probability variable big hit game, the upper prize winning opening 28 (upper prize winning door 28a) is opened in each round game. In addition, in 4R probability variable big hit games, depending on the game state at the time of winning the big hit lottery, the probability change state and the improved entrance rate (short time state) are given after the big hit game ends, and only the positive change state after the big hit game ends May be granted. Specifically, if the winning rate improvement state is given at the time of winning the big hit lottery, the probability variation state and the increased winning rate state are given until the next big hit game after the end of the big hit game. In addition, if the winning rate improvement state is not given at the time of winning the big hit lottery, the probability variation state is given after the big hit game ends, but the winning rate improvement state is not given.

  In addition, in the 4R probable big hit game, the opening time is “10 (seconds)”, the round game time of one round game is “0.1 (second)”, and the ending time is “1 (second)”. Is set. Although not shown in FIG. 3, the interval time between rounds in the 4R probability variation big hit game is set to “1.0 (seconds)”.

  The jackpot game given when the jackpot symbol classified as symbol D is displayed on the first special symbol display H0 or when the jackpot symbol classified as symbol d is displayed on the second special symbol display H1. Is a “4R non-probable change big hit game” in which the specified number of rounds is set to “4” and the probability change state is not given after the big hit game ends. In the four round games in the 4R non-probability big hit game, each of the round games is set so that the upper prize winning opening 28 (upper prize winning opening door 28a) is opened. Also, in the 4R non-probability big hit game, there are cases where a state of improving the entrance rate is given after the big hit game is ended or not given depending on the game state at the time of winning the big hit lottery. Specifically, if a winning rate improvement state is given at the time of winning the big hit lottery, the number of times determined in advance after the big hit game (in this embodiment, 100 times) is set as the upper limit number of times. Is granted. In addition, if the winning rate improvement state is not given at the time of winning the big hit lottery, the entering rate improvement state is not given.

  In the 4R non-probable big hit game, the opening time is “10 (seconds)”, the round game time of one round game is “0.1 (seconds)”, and the ending time is “1 (seconds)”. Each is set. Although not shown in FIG. 3, the interval time between rounds in the 4R non-probability big hit game is set to “1.0 (seconds)”.

  In addition, in 4R probabilistic big hit games or 4R non-probable big hit games, the round game time of each round game may end when the number of game balls for each round game enters, Maximum time. However, the round game time (0.1 (seconds)) of 4R probability variable big hit game or 4R non-variable big hit game is the number of game balls that enter the upper grand prize opening 28 in one round game, The time is set so as not to satisfy the maximum number of balls entered. Incidentally, in the pachinko gaming machine 10, the number of game balls fired per minute is set to approximately “100 balls”, so the time required to fire one game ball is “0.6 (seconds)”. It becomes. That is, in each round game of 4R probable big hit game or 4R non-probable big hit game, within 10 hours of round game time (0.1 (seconds)), "10 balls" that will be the upper limit of the number of balls, It is virtually impossible to enter.

  From the above, the opening mode of the top big winning opening 28 in the 4R non-probable big hit game is the same as the opening mode of the top big winning opening 28 in the 4R probable big hit game. It cannot be judged. Also, if a winning rate improvement state is given at the time of winning the big hit lottery, a predetermined number of times the winning rate improvement state is given after the end of the big hit game, and the winning rate at the time of winning the big hit lottery If the improved state is not given, the entrance rate improved state is not given. For this reason, until the predetermined number of symbol variation games are executed after the end of the big hit game, it cannot be determined whether or not the probability variation state is imparted depending on whether or not the entrance rate improvement state is imparted. It has become.

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). An effect control board 31 is mounted on the back side of the machine. The effect control board 31 controls the display mode (display images of symbols, backgrounds, characters, etc.) of the variable display H2 based on the control signal (control command) output from the main control board 30.

Hereinafter, specific configurations of the main control board 30 and the effect control board 31 will be described.
The main control board 30 is provided with a main CPU 30a. A ROM 30b and a RAM 30c are connected to the main CPU 30a. The main CPU 30a is connected with a first start port sensor SE1, a second start port sensor SE2, a count switch SE3, a count switch SE4, and the like. The main CPU 30a is connected to a first special figure display H0, a second special figure display H1, a first hold indicator Ra, and a second hold indicator Rb. The main CPU 30a is connected to a special winning opening solenoid SOL1 and a normal electric accessory solenoid SOL2. The main CPU 30a is connected to a normal symbol display H10 and a gate sensor SE5. Further, the main CPU 30a updates the values of various random numbers such as a hit determination random number every predetermined period, stores (sets) the updated values in the setting area of the RAM 30c, and rewrites the values before the update.

  A main control program for controlling the entire pachinko machine 10 is stored in the ROM 30b. The ROM 30b stores a plurality of types of variation patterns. The variation pattern is a game effect (display effect, light emission) from when the symbol (special symbol and decoration) starts to change (the symbol variation game starts) until the symbol is stopped (the symbol variation game ends). This shows a pattern serving as a base for production and voice production. In other words, the variation pattern is the effect of the symbol variation game (presence / absence of jackpot, presence / absence of reach, type of jackpot game) and performance time from when the special chart starts to change until the special chart is confirmed and stopped. (Variation time) can be specified.

  As shown in FIG. 4, the variation pattern is a variation pattern P1 to P3 for the jackpot effect that is selected when winning the jackpot determination, and a variation effect that is selected in the case of a loss that has not been won for the jackpot determination. It consists of fluctuation patterns P4 to P7. In the variation pattern for the offense effect, a reach is formed, and after the reach effect is performed, the variation pattern P4 to P6 for the outlier reach effect that is finally deviated and the outlier effect that is regarded as a deviation without forming the reach Variation pattern P7.

  In the present embodiment, the variation pattern for the big hit effect includes a variation pattern P1 selected when the 16R special probability variable big hit game is determined. The variation pattern for the big hit effect includes a variation pattern P2 selected when the 16R special probability variable big hit game or the 16R normal probability variable big hit game is determined. Further, the variation pattern for the big hit effect includes a variation pattern P3 selected when the 16R special probability variable big hit game, the 4R probability variable big hit game or the 4R non-probable big hit game is determined.

  Note that the jackpot effect performed based on the variation patterns P1 and P2 is an effect that the symbol variation game is developed so that the symbol combination is finally stopped and displayed through the reach effect. The outlier reach effect is an effect that is developed so that the symbol variation game undergoes the reach effect, and finally displays the combination of symbols that are out of place. The outlier effect is an effect that is developed so that the symbol variation game finally displays the symbol combination of the outage without being subjected to the reach effect. The reach effect is an effect that is performed after the reach symbol combination is formed in the symbol variation game with the decorative symbol of the variable display H2 until the jackpot symbol combination or the outlier symbol combination is derived. .

Hereinafter, each variation pattern will be described in detail.
When the 16R jackpot game is awarded and the first variation game is played based on the variation patterns P1 to P3 for the jackpot effect, the first special figure display H0 and the variable display H2 are each a big hit. The jackpot symbol and the jackpot symbol combination that can be recognized are finally displayed. In addition, when the second variation game is performed based on the variation patterns P1 to P3 for the big hit effect, the big special symbol and the big hit that can recognize the big hit respectively on the second special figure display H1 and the variable display H2. The symbol combination is finally displayed.

  When the first variation game is played based on the variation pattern P3 selected when the 4R probability variable big hit game or the 4R non-probable big hit game is determined, the big hit symbol is variably displayed on the first special figure display H0. The symbol combinations suggesting the probable change are finally displayed on the vessel H2. Similarly, when the second variation game is performed based on the variation pattern P3 selected when the 4R probability variable big hit game or the 4R non-probability big hit game is determined, the big hit symbol is variable on the second special figure display H1. The symbol combinations suggesting the probable change are finally displayed on the display H2.

  Further, when the first variation game is performed based on the variation patterns P4 to P6 for the outlier reach effect, the first special figure display device H0 and the variable display device H2 respectively include the outlier symbol and the outlier (outlier reach) symbol. The combination is finally displayed. Similarly, when the second variation game is performed based on the variation patterns P4 to P6 for the outlier reach effect, the second special-figure display H1 and the variable display H2 respectively have a deviation symbol and a deviation (outlier reach). The symbol combination is finally displayed.

  Then, when the first variation game is performed based on the variation pattern P7 for the offending effect, after the normal variation on the first special symbol display H0 and the variable display H2, the combination of the deviating symbol and the deviating symbol combination is final. It is designed to be displayed. When the second variation game is performed based on the variation pattern P7 for the offending effect, after the normal variation on the second special symbol display H1 and the variable display H2, the combination of the symbol and the symbol combination of the disparity is finally obtained. The pattern is displayed.

  In addition, the jackpot determination value is stored in the ROM 30b. The jackpot determination value is a determination value used in the internal lottery to determine whether or not the jackpot is reached, and is determined from numerical values (all 1439 integers from 0 to 1438) that the jackpot determination random number can take. The number of jackpot determination values differs depending on whether or not the probability variation state is given. The number of jackpot determination values in the probability variation state (36 in this embodiment) is the jackpot determination value in the normal state. Is set to be larger than the number (four in this embodiment). The RAM 30c stores a big hit determination random number used when determining the big hit.

  In the present embodiment, the jackpot determination random number is acquired when the game ball wins the first start winning opening 25 or the second starting winning opening 27, and the first variation game and the second It is commonly used in fluctuating games. In other words, the jackpot determination random number acquired when the game ball wins the first start winning opening 25 is the same as the jackpot determination random number acquired when the game ball wins the second start winning opening 27. belongs to. The jackpot determination value is also commonly used in the first variable game and the second variable game. That is, the jackpot determination value used in the jackpot determination value based on the first special figure start reserved memory number is the same as the jackpot determination value used in the jackpot determination based on the second special figure start hold memory number.

  The RAM 30c stores special figure distribution random numbers used when determining the type of special figure that becomes a big hit symbol when the big hit is determined. In each special figure, this special figure distribution random number is distributed by a predetermined number (one in this embodiment), and the main CPU 30a acquires it when the big hit is determined (when the big hit determination is affirmative). The jackpot symbol is determined based on the special distribution random number. The special CPU distribution random number is set so that the main CPU 30a can take a numerical value within a predetermined numerical value range (in the present embodiment, all 100 kinds of integers from “0” to “99”) at predetermined intervals. The value is updated by adding 1 to the value (every 4 ms). Then, the main CPU 30a stores the updated values in the RAM 30c as special figure distribution random number values, and sequentially updates the special figure distribution random number values by rewriting the already stored special figure distribution random number values. It is supposed to be. In the present embodiment, the special figure distribution random number is acquired when the game ball has won the first start winning opening 25 or the second starting winning opening 27. Commonly used in two fluctuation games. That is, the special distribution random number acquired when the game ball wins the first start winning opening 25 is the special distribution random number acquired when the game ball wins the second start winning opening 27. Is the same.

  Note that the jackpot symbol determined by which of the first variation game and the second variation game is executed is one of the symbols A to D (in the case of the second variation game, the symbols a, c, d) Which group is classified. Specifically, [0] indicating that the first variation game is to be executed is set in the special symbol variation processing flag indicating that either the first variation game or the second variation game is to be executed. If it is, it is classified into any group of symbols A to D. Further, when [1] indicating that the second variation game is performed is set in the special symbol variation processing flag, the special symbol variation processing flag is classified into any one of the symbols a, c, and d. .

  Further, the RAM 30c stores a reach determination random number used when determining whether or not to execute the reach effect when the big hit determination is lost. The reach determination random number is a numerical value for each predetermined period (every 4 ms) so that the main CPU 30a can take a numerical value within a predetermined numerical range (in this embodiment, a total of 241 integers from 0 to 240). 1 is added and updated. Then, the main CPU 30a stores the updated value in the RAM 30c as the reach determination random number value, and sequentially updates the reach determination random number value by rewriting the already stored reach determination random number value. It has become. In the present embodiment, the reach determination random number is acquired when a game ball wins the first start winning opening 25 or the second starting winning opening 27.

  In addition, the reach determination value is stored in the ROM 30b. The reach determination value is a determination value used in reach lottery (reach determination) for determining whether or not a reach effect is to be executed when the symbol variation game is out of place, and a reach determination random number (from 0 to 240). 241 types of integers). Note that the number of reach determination values varies depending on the presence / absence of the probability variation state, the presence / absence of the entrance rate improvement state, and the number of stored starting balls.

Next, the effect control board 31 will be described with reference to FIG.
The effect control board 31 is provided with a sub CPU 31a. A ROM 31b and a RAM 31c are connected to the sub CPU 31a. Further, the sub CPU 31a updates the values of various random numbers at predetermined intervals, stores (sets) the updated values in the setting area of the RAM 31c, and rewrites the values before the update. The ROM 31b stores an effect control program for executing a game effect. Sub CPU31a will perform various control based on the said presentation control program, if various control commands are inputted. The ROM 31b stores various image data (image data such as symbols, various background images, characters, and characters). The effect button 40 is connected to the effect control board 31 (sub CPU 31a), and a detection signal indicating that the effect button 40 has been operated is input from the effect button 40.

  Next, various processes such as a special symbol input process and a special symbol start process executed by the main CPU 30a based on the main control program will be described. First, the special symbol input process will be described with reference to FIG. The special symbol input process is executed at predetermined intervals by the main CPU 30a.

  The main CPU 30a determines whether or not a game ball has entered the first start winning opening 25 (step S1). That is, in step S1, the main CPU 30a determines whether or not a first detection signal output when the first start port sensor SE1 detects a game ball is input. When the determination result of step S1 is negative, the main CPU 30a proceeds to step S5. When the determination result of step S1 is affirmative, the main CPU 30a determines whether or not the first special figure start pending storage number stored in the RAM 30c is less than the upper limit number of 4 (step S2). If the determination result of step S2 is negative (first special figure start hold storage number = 4), the main CPU 30a proceeds to step 5.

  When the determination result of step S2 is affirmative (first special figure start reserved memory number <4), the main CPU 30a adds 1 to the first special figure start reserved memory number and rewrites the first special figure start reserved memory number ( Step S3). At this time, the main CPU 30a controls the display content of the first hold indicator Ra so as to represent the first special figure start hold memory number after 1 addition. Subsequently, the main CPU 30a reads and acquires the value of the reach determination random number, the value of the jackpot determination random number, and the value of the special figure distribution random number from the RAM 30c, and obtains the value as the first special figure start pending storage number. The predetermined storage area of the associated RAM 30c is set (step S4).

  Next, the main CPU 30a determines whether or not a game ball has entered the second start winning opening 27 (step S5). That is, in step S5, the main CPU 30a determines whether or not a second detection signal output when the second start port sensor SE2 detects a game ball is input. When the determination result of step S5 is negative, the main CPU 30a ends the special symbol input process. If the determination result of step S5 is affirmative, the main CPU 30a determines whether or not the second special figure start pending storage number stored in the RAM 30c is less than the upper limit number of 4 (step S6). If the determination result of step S6 is negative (second special figure start hold storage number = 4), the main CPU 30a ends the special symbol input process.

  If the determination result of step S6 is affirmative (second special figure start reserved memory number <4), the main CPU 30a adds 1 to the second special figure start reserved memory number and rewrites the second special figure start reserved memory number ( Step S7). At this time, the main CPU 30a changes the display content of the second hold indicator Rb so as to represent the second special figure start hold memory number after 1 addition. Subsequently, the main CPU 30a reads out and acquires the value of the reach determination random number, the value of the jackpot determination random number, and the value of the special figure distribution random number from the RAM 30c, and obtains the value as the second special figure start pending storage number. A predetermined storage area of the associated RAM 30c is set (step S8). Thereafter, the main CPU 30a ends the special symbol input process.

Next, the special symbol start process will be described with reference to FIGS. The main CPU 30a executes a special symbol start process every predetermined cycle.
First, the main CPU 30a determines whether or not the symbols (special drawings and decorative drawings) are being displayed in a variable manner and whether or not the jackpot game is being played (step S11). When the determination result of step S11 is affirmative, the main CPU 30a ends the special symbol start process. On the other hand, if the determination result of step S11 is negative, the main CPU 30a reads the second special figure start reserved memory number (step S12), and determines whether the second special figure start reserved memory number is greater than "0". (Step S13).

  When the determination result of step S13 is negative (when the second special figure start hold memory number = 0), the main CPU 30a reads the first special figure start hold memory number (step S14), and the first special figure start hold memory is stored. It is determined whether or not the number is larger than “0” (step S15). When the determination result of step S15 is negative (when the first special figure start hold storage number = 0), the main CPU 30a ends the special symbol start process.

  On the other hand, if the determination result in step S15 is affirmative (if the first special figure start hold storage number> 0), the main CPU 30a sets the first symbol variation processing flag stored in the predetermined storage area of the RAM 30c to the first variation. A value [0] indicating that the game is to be executed is set (step S16). Next, the main CPU 30a subtracts “1” from the number of the first special figure start hold memory number (step S17), and stores it in a predetermined storage area of the RAM 30c in association with the first special figure start hold memory number. The jackpot determination random number, reach determination random number, and special figure distribution random number are acquired (step S18).

  More specifically, the main CPU 30a reads various random numbers stored in the first storage area associated with the first special figure start hold storage number “1” stored earliest. Further, after reading the random number, the main CPU 30a uses the random number stored in the first storage area associated with the first special figure start hold storage number “2” as the first special figure start hold storage number “1”. Is stored in the first storage area associated with "." Similarly, the main CPU 30a associates various random numbers stored in the first storage area associated with the first special figure start hold memory number “3” with the first special figure start hold memory number “2”. Stored in the first storage area. Similarly, the main CPU 30a associates various random numbers stored in the first storage area associated with the first special figure start hold memory number “4” with the first special figure start hold memory number “3”. Stored in the first storage area. Further, the main CPU 30a erases various random numbers stored in the first storage area associated with the first special figure start hold storage number “4”. Further, when the main CPU 30a subtracts 1 from the first special figure start reserved memory number, the main CPU 30a changes the display content of the first hold indicator Ra so as to represent the first special figure start reserved memory number after 1 subtraction.

  Next, as shown in FIG. 7, the main CPU 30a determines whether or not the acquired jackpot determination random number value matches the jackpot determination value stored in the ROM 30b and performs a jackpot determination (hit lottery). (Step S19). In the present embodiment, the jackpot determination value is changed depending on whether or not the probability variation state is given. In the normal state (when the probability is low), the probability that the determination result of the jackpot determination is affirmative (the jackpot probability) is 4/1439. When the probability change state (when the probability is high), the determination of the jackpot determination The probability that the result is affirmative (big hit probability) is 36/1439.

  When the determination result of step S19 is affirmative (in the case of a big hit), the main CPU 30a sets [1] to a big hit flag indicating that it is a big hit variation (step S20). Then, the main CPU 30a determines a final stop symbol to be fixedly stopped and displayed on the first special symbol display H0 from the big hit symbols based on the special diagram based on the value of the acquired special symbol distribution random number (step S21). . Thereafter, the main CPU 30a identifies the type of jackpot game from the determined final stop symbol, and determines a variation pattern for jackpot effect corresponding to the identified jackpot game (step S22).

  Specifically, when the determined final stop symbol is classified as symbol A, the main CPU 30a determines the variation pattern P1 to P3 for jackpot effect. When the determined final stop symbol is classified as symbol B, the main CPU 30a determines a variation pattern P2 for jackpot effect. In addition, when the determined final stop symbol is classified into symbols C and D, the main CPU 30a determines a variation pattern P3 for jackpot effect.

  The main CPU 30a, which has determined the variation pattern and the final stop symbol, executes various processes relating to the first variation game, such as outputting a predetermined control command at a predetermined timing to the effect control board 31 (sub CPU 31a) (step). S23). Specifically, the main CPU 30a first outputs a variation pattern designation command that designates a variation pattern and instructs the start of symbol variation. At the same time, the main CPU 30a controls the display content of the first special figure display H0 so that the special figure starts to fluctuate. At the same time, the main CPU 30a starts measuring the effect time of the symbol variation game. Further, the main CPU 30a outputs a special symbol designation command for designating the final stop symbol. Then, the main CPU 30a ends the special symbol start process. Thereafter, in a process different from the special symbol start process, the main CPU 30a displays the determined final stop symbol on the first special symbol display H0 based on the effect time determined in the designated variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  On the other hand, when the determination result of the big hit determination of step S19 is negative (when it is not a big hit), the main CPU 30a performs a reach determination for determining whether or not to execute the reach effect (step S24). In the present embodiment, the main CPU 30a determines whether or not the reach determination random number acquired from the RAM 30c during the process of step S24 matches the reach determination value.

  If the determination result of step S24 is affirmative (when a reach effect is performed), the main CPU 30a determines the off symbol as a final stop symbol that is confirmed and stopped on the first special symbol display H0 (step S25). . Next, the main CPU 30a determines a variation pattern from among the variation patterns P4 to P6 for the outlier reach effect (step S26). Then, the main CPU 30a that has determined the variation pattern and the final stop symbol moves to the process of step S23, and outputs a predetermined control command to the effect control board 31 (sub CPU 31a) at a predetermined timing. Various processes related to the variable game are executed. Thereafter, the main CPU 30a ends the special symbol start process. The main CPU 30a is a process different from the special symbol start process, and the main CPU 30a displays the determined final stop symbol based on the effect time set in the specified variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  On the other hand, when the determination result of step S24 is negative (when the reach effect is not performed), the main CPU 30a determines the missed symbol as the final stop symbol that is confirmed and stopped on the first special symbol display H0 (step S27). ). Next, the main CPU 30a determines the variation pattern P7 for the offending effect (step S28).

  Then, the main CPU 30a that has determined the variation pattern and the final stop symbol moves to the process of step S23, and outputs a predetermined control command to the effect control board 31 (sub CPU 31a) at a predetermined timing. Various processes related to the variable game are executed. Thereafter, the main CPU 30a ends the special symbol start process. The main CPU 30a is a process different from the special symbol start process, and the main CPU 30a displays the determined final stop symbol based on the effect time set in the specified variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  On the other hand, when the determination result in step S13 is affirmative (when the second special figure start hold storage number> 0), the main CPU 30a changes the special symbol variation stored in a predetermined storage area of the RAM 30c as shown in FIG. A value [1] indicating that the second variation game is to be executed is set in the processing flag (step S29). Next, the main CPU 30a subtracts “1” from the number of the second special figure start reserved memory number (step S30), and stores it in a predetermined storage area of the RAM 30c in association with the second special figure start reserved memory number. The jackpot determination random number, reach determination random number, and special figure distribution random number are acquired (step S31).

  More specifically, the main CPU 30a reads various random numbers stored in the second storage area associated with the second special figure start hold storage number “1” stored earliest. In addition, after reading the random number, the main CPU 30a uses the random number stored in the second storage area associated with the second special figure start hold storage number “2” as the second special figure start hold storage number “1”. Is stored in the second storage area associated with "." Similarly, the main CPU 30a associates various random numbers stored in the second storage area associated with the second special figure start hold storage number “3” with the second special figure start hold storage number “2”. Stored in the first storage area. Similarly, the main CPU 30a associates various random numbers stored in the second storage area associated with the second special figure start hold storage number “4” with the second special figure start hold storage number “3”. Stored in the second storage area. Further, the main CPU 30a erases various random numbers stored in the second storage area associated with the second special figure start hold storage number “4”. Further, the main CPU 30a changes the display content of the second hold indicator Rb so as to represent the second special figure start reserved memory number after 1 subtraction when the second special figure start hold memory number is subtracted by 1.

  Next, as shown in FIG. 8, the main CPU 30 a determines whether or not the acquired hit determination random number value matches the jackpot determination value stored in the ROM 30 b and performs a jackpot determination (big hit lottery). (Step S32). In the present embodiment, in the normal state (when the probability is low), the probability that the determination result of the jackpot determination is affirmative (the jackpot probability) is 4/1439, and when the probability change state (when the probability is high). The probability that the determination result of the jackpot determination is affirmative (the jackpot probability) is 36/1439.

  When the determination result in step S32 is affirmative (in the case of a big hit), the main CPU 30a sets [1] to a big hit flag indicating that the hit is a fluctuation (step S33). Then, the main CPU 30a determines a final stop symbol to be finalized and stopped on the second special symbol display H1 from the jackpot symbols based on the special diagram based on the acquired special symbol distribution random value (step S34). .

  After the process of step S34, the main CPU 30a identifies the type of jackpot game from the determined final stop symbol, and determines the variation patterns P1 to P3 for the jackpot effect corresponding to the identified jackpot game (step S35). Specifically, when the determined final stop symbol is classified as symbol a (that is, when the 16R special probability variable big hit game is decided), the main CPU 30a changes the big hit effect variation patterns P1 to P3. Decide from the inside. Further, when the determined final stop symbol is classified into symbols c and d (that is, when 4R probability variable big hit game or 4R non-probable variable big hit game is determined), the main CPU 30a changes the big hit effect variation pattern P3. To decide.

  The main CPU 30a, which has determined the variation pattern and the final stop symbol, executes various processes related to the second variation game, such as outputting a predetermined control command at a predetermined timing to the effect control board 31 (sub CPU 31a) (step). S36). Specifically, the main CPU 30a first outputs a variation pattern designation command that designates a variation pattern and instructs the start of symbol variation. At the same time, the main CPU 30a controls the display content of the second special figure display H1 so that the special figure starts to fluctuate. At the same time, the main CPU 30a starts measuring the effect time of the symbol variation game. Further, the main CPU 30a outputs a special symbol designation command for designating the final stop symbol. Then, the main CPU 30a ends the special symbol start process. Thereafter, in a process different from the special symbol start process, the main CPU 30a displays the determined final stop symbol on the second special symbol display H1 based on the effect time determined in the designated variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  On the other hand, when the determination result of the big hit determination in step S32 is negative (not the big hit), the main CPU 30a performs a reach determination for determining whether or not to execute the reach effect (step S37). In the present embodiment, the main CPU 30a determines whether or not the reach determination random number acquired from the RAM 30c during the process of step S31 matches the reach determination value.

  If the determination result in step S37 is affirmative (when a reach effect is performed), the main CPU 30a determines the off symbol as a final stop symbol that is confirmed and stopped on the second special symbol display H1 (step S38). . Next, the main CPU 30a determines a variation pattern from among the variation patterns P4 to P6 for the outlier reach effect (step S39). Then, the main CPU 30a having determined the variation pattern and the final stop symbol moves to the process of step S36, and outputs a predetermined control command to the effect control board 31 (sub CPU 31a) at a predetermined timing. Various processes related to the variable game are executed. Thereafter, the main CPU 30a ends the special symbol start process. The main CPU 30a is a process different from the special symbol start process, and the main CPU 30a displays the determined final stop symbol on the second special symbol display H1 based on the effect time determined in the designated variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  On the other hand, when the determination result of step S37 is negative (when the reach effect is not performed), the main CPU 30a determines the off symbol as the final stop symbol that is confirmed and stopped on the second special symbol display H1 (step S40). ). Next, the main CPU 30a determines the variation pattern P7 for the offending effect (step S41).

  Then, the main CPU 30a having determined the variation pattern and the final stop symbol moves to the process of step S36, and outputs a predetermined control command to the effect control board 31 (sub CPU 31a) at a predetermined timing. Various processes related to the variable game are executed. Thereafter, the main CPU 30a ends the special symbol start process. The main CPU 30a is a process different from the special symbol start process, and the main CPU 30a displays the determined final stop symbol on the second special symbol display H1 based on the effect time determined in the designated variation pattern. Controls the display content of. Further, the main CPU 30a instructs decoration stoppage of the decorative drawing based on the effect time set in the specified change pattern, and outputs an all symbol stop command for causing the symbol combination to be fixedly stopped.

  By executing such a special symbol start process, when both the first special figure start reserved memory number and the second special figure start reserved memory number are stored, the main CPU 30a performs the second variable game. Is executed preferentially. The second start winning opening 27 has the open / close blade 26 open to facilitate the winning of the game ball when the improved winning rate is given, and as a result, the improved winning rate is given. In the probability variation state or the short time state, the second variation game is easily executed continuously. And, when a big hit is made in the second floating game, the ratio of whether or not the probability variation state is given is not different from that in the first variation game, but when the probability variation state is given, which jackpot game is given Easy or different. That is, when the distribution of the special figure distribution random numbers is different and the second variable game is a big hit, the 16R special probability variable big hit game is likely to be awarded. In the 16R special probability variable big hit game, the opening times of the big winning openings 28 and 29 are longer than in other big hit games, and it is easy to win a prize ball. As a result, when a big hit is achieved in the second variable game, it is possible to expect a prize ball to be obtained more than in the first variable game. Therefore, when a big hit is made when the entrance rate improvement state is given, it is more advantageous for the player than when the entrance rate improvement state is not given.

  As described above, in the present embodiment, the upper prize winning opening 28 and the lower prize winning opening 29 serve as special winning means. The variable display H2 serves as an effect execution means. The main CPU 30a serves as a jackpot determining means, a jackpot game giving means, and a probability variation determining means.

  When the main CPU 30a determines the big hit (when [1] is set in the big hit flag), after the end of the symbol variation game based on the determined variation pattern, the type of jackpot game specified based on the final stop symbol And a predetermined control command is output at a predetermined timing to the effect control board 31 (sub CPU 31a). Hereinafter, the control contents executed by the main CPU 30a will be described for each jackpot game.

  First, the control when the 16R special probability variable big hit game is awarded will be described. The main CPU 30 a first outputs an opening command for instructing execution of the opening effect to the effect control board 31. Next, the main CPU 30a controls each round game after the opening effect ends. That is, the main CPU 30a outputs a round command instructing the start of a round game to the effect control board 31 at the start of each round game, and controls the opening and closing of the top prize winning opening 28. In addition, when the 16R special probability variable big hit game is awarded, the main CPU 30a controls to open the top prize winning opening 28 by setting the round game time of the first to sixteenth rounds to a maximum of 25 seconds.

  Then, when the final round game is finished, the main CPU 30a outputs an ending command for instructing execution of the ending effect to the effect control board 31. Thereafter, the main CPU 30a ends the big hit game when the ending effect ends. The main CPU 30a sets (clears) the big hit flag to [0].

  At that time, when the 16R special probability variation big hit game is awarded, the main CPU 30a sets the probability variation flag indicating that the probability variation state is imparted to “1” and indicates that the entry rate improvement state is imparted. Set the operation flag to “1”. When “1” is set in the probability variation flag, it indicates that the probability variation state is assigned, and when “0” is set, it indicates that the probability variation state is not imparted. ing. Similarly, when the operation flag is set to “1”, it indicates that the entrance rate improvement state is given, and when “0” is set, the entrance rate improvement state is set. Indicates that it has not been granted.

  Next, the control when a 16R normal probability variation big hit game is awarded will be described. The main CPU 30 a first outputs an opening command for instructing execution of the opening effect to the effect control board 31. Next, the main CPU 30a controls each round game after the opening effect ends. That is, the main CPU 30a outputs a round command instructing the start of a round game to the effect control board 31 at the start of each round game, and controls the opening and closing of the lower prize winning opening 29. Note that when the 16R normal probability variable big hit game is awarded, the main CPU 30a controls to open the lower big prize opening 29 by setting the round game time from the 1st to the 10th round to a maximum of 25 seconds, and the 11th to 16th rounds. Control is made so that the lower prize opening 29 is opened with a maximum round game time of 0.1 seconds.

  Then, when the final round game is finished, the main CPU 30a outputs an ending command for instructing execution of the ending effect to the effect control board 31. Thereafter, the main CPU 30a ends the big hit game when the ending effect ends. The main CPU 30a sets (clears) the big hit flag to [0]. When the 16R normal probability variation big hit game is awarded, the main CPU 30a sets “1” to the probability variation flag indicating that the probability variation state is imparted, and sets the operation flag indicating that the entrance rate improvement state is imparted. Set “1”.

  Next, the control when 4R probability variable big hit game or 4R non-probable big hit game is given will be described. The main CPU 30 a first outputs an opening command for instructing execution of the opening effect to the effect control board 31. Next, the main CPU 30a controls each round game after the opening effect ends. That is, the main CPU 30a outputs a round command instructing the start of a round game to the effect control board 31 at the start of each round game, and controls the opening and closing of the top prize winning opening 28. When the 16R normal probability variable big hit game is awarded, the main CPU 30a controls to open the top prize winning opening 28 by setting the round game time from the first to fourth rounds to a maximum of 0.1 seconds.

  Then, when the final round game is finished, the main CPU 30a outputs an ending command for instructing execution of the ending effect to the effect control board 31. Thereafter, the main CPU 30a ends the big hit game when the ending effect ends. The main CPU 30a sets (clears) the big hit flag to [0].

  When the 4R probability variation big hit game is awarded, the main CPU 30a sets “1” in the probability variation flag. In addition, when a 4R probability variable big hit game is awarded, if the operation flag is set to “1” at the start of the symbol variation game in which the 4R probability variable big hit game is given (the entry rate improvement state is given) And “1” is set in the operation flag. On the other hand, when the 4R probability variable big hit game is awarded, the main CPU 30a does not set “1” in the operation flag at the start of the symbol variation game to which the 4R probability variable big hit game is awarded (the increased entrance rate state is set). If it is not given, the operation flag is not set to “1” (set to “0”).

  On the other hand, when the 4R non-probability big hit game is awarded, the main CPU 30a sets the probability change flag to “0”. In addition, when a 4R non-probability big hit game is awarded, if the operation flag is set to “1” at the start of the symbol variation game in which the 4R non-probability big hit game is given (the improved entry rate state is given) If this is the case, “1” is set in the operation flag, and 100 times is set as the number of operations indicating the number of remaining symbol variation games to which the improved entrance rate is given. The number of operations is decremented by 1 every time the symbol variation game is executed, and when the value becomes 0, the operation flag is cleared ("0" is set). Each flag and the number of operations are cleared (“0” is set) even when a big hit game is awarded.

  On the other hand, when the 4R non-probability variable big hit game is awarded, the main CPU 30a does not set “1” in the operation flag at the start of the symbol variation game in which the 4R non-probable big hit game is given (improves the entrance rate) If the state is not given), the operation flag is set to “0”.

  In this embodiment, by executing the 4R probability variation big hit game and the 4R non-probability big hit game in this embodiment, the effect content of the symbol variation game, the effect content of the big hit game, the presence / absence of the improved entrance rate after the end of the big hit game, etc. Are the same. Therefore, after the 4R probability variation big hit game and the 4R non-probability big hit game are finished, it is concealed as to whether or not the probability variation state is given.

  Next, various processes executed by the sub CPU 31a of the effect control board 31 based on the overall control program will be described. When a predetermined control command is input from the main CPU 30a at a predetermined timing, the sub CPU 31a executes various processes accordingly.

  For example, when the sub CPU 31a inputs a variation pattern designation command, the sub CPU 31a controls the variable display H2 to execute the symbol variation game based on the variation pattern designated by the variation pattern designation command. Further, when the sub CPU 31a inputs the variation pattern designation command and the special symbol designation command, the sub CPU 31a displays the variable display H2 based on the variation pattern designated by the variation pattern designation command and the final stop symbol designated by the special symbol designation command. The combination of symbols based on the decorative symbols to be confirmed and stopped is determined. Further, when the big hit symbol is designated as the final stop symbol, the sub CPU 31a determines the specific contents of the big hit game based on the type of the big hit game corresponding to the big hit symbol. The sub CPU 31a is configured to execute a game effect related to the jackpot game based on the specific contents of the determined jackpot game during the jackpot game. That is, when the opening command, the round command, and the ending command are input, the sub CPU 31a causes the variable display H2 to execute the opening effect, the round effect, and the ending effect based on the specific effect contents of the determined jackpot game. ing. In addition, when the 16R special probability variable big hit game or the 16R normal probability variable big hit game is given, the sub CPU 31a notifies that the probability changed state is given after the big hit game is ended in the ending effect.

  Next, a detailed process for determining a symbol combination (hereinafter also simply referred to as a fixed symbol) based on a decorative symbol to be displayed on the variable display H2 at a fixed stop at the end of the symbol variation game will be described.

  When the final stop symbol designated by the special symbol designation command is the special symbol A, B, or a, the sub CPU 31a determines the jackpot symbol combination as the confirmed symbol. In the present embodiment, the jackpot symbol combination is [111] [222] [333] [444] [555] [666] [777] [888]. In addition, it is possible to recognize that the probability variation state is given by displaying the big hit symbol combination. On the other hand, it is impossible to recognize which of the 16R special probability variable big hit games and the 16R normal probability variable big hit games will be awarded. Further, the sub CPU 31a determines the symbol combination of the probability variation suggestion as the confirmed symbol when the final stop symbol designated by the special symbol designation command is the special symbol C, D, c, d.

  In addition, when the designated final stop symbol is an outlier design and the variation patterns P4 to P6 for the outlier reach effect are designated, the sub CPU 31a designates the outlier reach symbol combination as the symbol combination by the ornament symbol. To decide. In addition, when the designated final stop symbol is an outlier symbol and the variation pattern P7 for the offending effect is designated, the sub CPU 31a determines the off symbol symbol combination as the symbol symbol symbol combination. Then, as described above, the sub CPU 31a displays the symbol combination of the determined decorative symbol in a fixed stop display according to the input of all symbol stop commands.

  In the present embodiment, after the 16R special probability variation big hit game or the 16R normal probability variation big hit game is finished, a probability variation mode is set as an effect mode for notifying that the probability variation state has been given. The probability variation mode is composed of a plurality of performance stages (stages), and when a predetermined transition condition is satisfied, the performance stage shifts to the next performance stage in a predetermined order. ing.

  More specifically, during the probability changing mode, the display image such as the background image and the appearance character changes according to the set stage of production. For this reason, it is possible to recognize which stage of the game effect is currently executed from the display image. In the present embodiment, the probability variation mode includes production stages of 1 to 3 stages. Then, as shown in FIG. 9, when the probability variation mode is set through the first 16R special probability variation big hit game or the 16R normal probability variation big hit game from the normal mode as the production mode in which the probability variation state cannot be expected to be given. A probability variation mode for the first stage is set. Then, when the stage for the first stage is set, a predetermined condition for shifting to the second stage is established, so that the probability changing mode for the stage for the second stage is set. Similarly, when the stage of the second stage is set, a predetermined stage transition condition to the third stage is established, and the probability changing mode of the stage of the third stage is set. Further, when the third stage stage is set, a predetermined achievement stage execution condition is satisfied, and after the achievement stage is executed, the probability change mode of the first stage stage is set again. Is done.

  In the present embodiment, as shown in FIG. 10, the background images are continuous over a plurality of (1 to 3) probability variation modes to form a story. Specifically, as shown in FIG. 10A, when the first stage probability change mode is set, a wilderness on the way to the castle is displayed as a background image. As shown in FIG. 10B, when the second-stage probability variation mode is set, a state of being around the castle is displayed as a background image. As shown in FIG. 10C, when the third-stage probability variation mode is set, a state in the castle is displayed as a background image. In this way, every time the production stage of the probability variation mode proceeds, it is shown that the castle is approached and advanced into the castle.

  Further, in this embodiment, as shown in FIG. 9, when the 4R probability variation big hit game or the 4R non-probability big hit game is given in the probability variation mode, the probability variation mode is ended and whether or not the probability variation state is given. A chance mode (probability change suggestion mode) is set as a production mode that cannot be recognized. The chance mode is set until a specific number of symbol variation games are completed or until the next jackpot game is awarded. In the present embodiment, the chance mode is set after the end of the jackpot game until the end of the short-time state (entrance rate improvement state) ends or until the next jackpot game is granted. Thereby, during the chance mode, the improved entrance rate is given.

  By the way, when the 16R special probability variable big hit game or the 16R normal probability variable big hit game is given again during the chance mode, the probability change mode at the stage set before shifting to the chance mode is set. In addition, after the chance mode is set, if the 100 symbol variation game is finished without the big hit game being given, the chance mode is continued as it is if the probability variation state and the entrance rate improvement state are given. It has become. On the other hand, after the chance mode is set, when 100 symbol variation games are finished without a big hit game being given, if the probability variation state is not given, the normal mode is set as the entrance rate improvement state is finished. It has come to be. As shown in FIG. 11A, the chance mode can be recognized from the display image such as the background image that the chance mode is currently set.

  In addition, as shown in FIG. 9, in the normal mode, when a 4R probability variable big hit game or a 4R non-probable big hit game is awarded, the normal mode is ended, and an effect mode in which it is not possible to recognize whether or not a probability changed state has been given. The latent mode (probability change suggestion mode) is set. The latent mode is set until the next jackpot game is awarded or until the falling lottery is won. In the present embodiment, a falling lottery is executed for each symbol variation game. For this reason, even in the normal mode, the probability variation state may be given, and the normal mode is also a kind of probability variation suggestion mode. As shown in FIG. 11B, the latent mode can be recognized from the display image such as the background image that the latent mode is currently set.

  Next, mode transition processing related to transition of the production mode will be described with reference to FIGS. The mode transition process is executed at the end of the symbol variation game (when all symbol stop commands are input).

  At the end of the symbol variation game, the sub CPU 31a refers to the value set in the mode flag stored in the RAM 30c to check what effect mode is set (step S100). The value set in the mode flag indicates what effect mode is set. Specifically, when “0” is set in the mode flag, it indicates that the normal mode is set. When “1” is set in the mode flag, it indicates that the first-stage probability variation mode is set. When “2” is set in the mode flag, it indicates that the second-stage probability variation mode is set. When “3” is set in the mode flag, it indicates that the third-stage probability variation mode is set. When “4” is set in the mode flag, it indicates that the chance mode is set. When “5” is set in the mode flag, it indicates that the latent mode is set.

  Next, the sub CPU 31a determines whether or not the value of the mode flag indicates the normal mode (mode flag = 0) (step S101). When the determination result is affirmative (when the normal mode is indicated), the sub CPU 31a determines whether any of the special symbols A, B, and a is specified by the special symbol designation command in the executed symbol variation game. Is determined (step S102). That is, it is determined whether or not the big hit symbol combination is displayed in a fixed stop state. If the determination result in step S102 is affirmative, the sub CPU 31a enters the first stage probability change mode after the ending effect of the big hit game (16R special probability variable big hit game or 16R normal probability variable big hit game) given after the end of the symbol variation game. A value “1” indicating the setting is set in the mode flag (step S103), and the mode transition process is terminated. When the mode flag is set to “1”, after the mode transition process is completed, the sub CPU 31a executes a process such as displaying a background image corresponding to the first stage probability change mode, and transitions the effect mode.

  On the other hand, if the determination result of step S102 is negative, the sub CPU 31a determines whether any of the special symbols C, D, c, and d is specified by the special symbol specifying command (step S104). If this determination result is negative, the sub CPU 31a ends the mode transition process as it is. On the other hand, if the determination result in step S104 is affirmative, the sub CPU 31a has set the latent mode after the end of the ending effect of the big hit game (4R probability change big hit game or 4R non-probability big hit game) given after the symbol variation game ends. Is set to the mode flag (step S105), and the mode transition process is terminated. When the mode flag is set to “5”, after the mode transition process is completed, the sub CPU 31a performs a process such as displaying a background image corresponding to the latent mode, and transitions the effect mode.

  On the other hand, when the determination result of step S101 is negative (when the normal mode is not indicated), the sub CPU 31a determines whether or not the mode flag value indicates the first stage probability change mode (mode flag = 1). Is determined (step S106). If the determination result is affirmative, the sub CPU 31a determines whether any of the special symbols A, B, and a is specified by the special symbol specifying command (step S107). If the determination result of step S107 is affirmative, the sub CPU 31a determines whether or not a mode transition condition to the second-stage probability variation mode is satisfied (step S108). In the present embodiment, the mode transition condition to the second stage probability change mode is that the jackpot game of either the 16R special probability change big hit game or the 16R normal probability change big hit game during the first stage probability change mode is a predetermined number of times (this embodiment) In this case, it must be granted 5 times).

  If the determination result of step S108 is affirmative, the sub CPU 31a sets a value “2” indicating that the second-stage probability variation mode is set to the mode flag (step S109), and ends the mode transition process. When the mode flag is set to “2”, after the mode transition process is completed, the sub CPU 31a executes a process such as displaying a background image corresponding to the second-stage probability variation mode, and transitions the effect mode. On the other hand, if the determination result of step S108 is negative, the sub CPU 31a adds 1 to the number of times of 16R big hit game (16R special probability variable big hit game or 16R normal probability variable big hit game) given during the first stage probability change mode. Then, the stored contents of the RAM 31c are updated (step S110), and the mode transition process is terminated.

  If the determination result in step S107 is negative (if it is not one of the special figures A, B, and a), the sub CPU 31a designates one of the special figures C, D, c, and d by the special symbol designation command. It is determined whether or not (step S111). If the determination result in step S111 is affirmative, the sub CPU 31a sets the chance mode after the ending effect of the big hit game (either 4R probability variable big hit game or 4R non-probable big hit game) given after the symbol variation game ends. A value “4” indicating this is set in the mode flag (step S112). In step S112, the sub CPU 31a stores a value “1” indicating that the first-stage probability variation mode has been set in the history flag, and ends the mode transition process. The history flag is stored in the RAM 31c. When the mode flag is set to “4”, after the mode transition process is completed, the sub CPU 31a executes a process such as displaying a background image corresponding to the chance mode, and transitions the effect mode. When “4” is set in the mode flag, the sub CPU 31a displays a background image corresponding to the value set in the history flag, as shown in FIG. That is, the sub CPU 31a displays a notification image indicating the stage of production in the probability change mode set before the chance mode. Thereby, the player can easily confirm the stage of the probability variation mode set before the chance mode. If the determination result of step S111 is negative, the sub CPU 31a ends the mode transition process as it is.

  On the other hand, when the determination result of step S106 is negative (when the first stage probability change mode is not indicated), the sub CPU 31a indicates that the mode flag value indicates the second stage probability change mode (when mode flag = 2). It is determined whether or not (step S113). If the determination result is affirmative, the sub CPU 31a determines whether any of the special symbols A, B, and a is specified by the special symbol specifying command (step S114). If the determination result of step S114 is affirmative, the sub CPU 31a determines whether or not a condition for shifting to the third stage probability change mode is satisfied (step S115). In this embodiment, the mode transition condition to the third stage probability change mode is that a 16R special probability variable big hit game or a 16R normal probability variable big hit game is given a predetermined number of times (10 times in this embodiment) during the probability change mode, and This is based on the condition that a predetermined game effect has been executed.

  If the determination result of step S115 is affirmative, the sub CPU 31a sets a value “3” indicating that the third-stage probability variation mode is set to the mode flag (step S116), and ends the mode transition process. When the mode flag is set to “3”, after the mode transition process is completed, the sub CPU 31a performs a process such as displaying a background image corresponding to the third-stage probability change mode, and transitions the effect mode. On the other hand, if the determination result in step S115 is negative, the sub CPU 31a updates the stored contents of the RAM 31c by adding 1 to the number of 16R jackpot games given during the second stage probability change mode (step S117). ), The mode transition process is terminated.

  If the determination result in step S114 is negative (if it is not one of the special figures A, B, and a), the sub CPU 31a designates one of the special figures C, D, c, and d by the special symbol designation command. It is determined whether or not (step S118). If the determination result in step S118 is affirmative, the sub CPU 31a indicates that the chance mode is set after the ending effect of the big hit game (4R probability variable big hit game or 4R non-probable big hit game) given after the symbol variable game is ended. The value “4” is set in the mode flag (step S119). In step S119, the sub CPU 31a stores the value “2” indicating that the second-stage probability variation mode has been set in the history flag, and ends the mode transition process. When the mode flag is set to “4”, after the mode transition process is completed, the sub CPU 31a executes a process such as displaying a background image corresponding to the chance mode, and transitions the effect mode. When the mode flag is set to “4”, the sub CPU 31a displays a background image corresponding to the value set in the history flag. If the determination result of step S118 is negative, the sub CPU 31a ends the mode transition process.

  On the other hand, when the determination result of step S113 is negative (when the second-stage probability change mode is not indicated), the sub CPU 31a indicates the third-stage probability change mode (when mode flag = 3). It is determined whether or not (step S120). If the determination result is affirmative, the sub CPU 31a determines whether any of the special symbols A, B, and a is specified by the special symbol specifying command (step S121). If the determination result of step S121 is affirmative, the sub CPU 31a determines whether or not the achievement effect execution condition is satisfied (step S122). In the present embodiment, the achievement effect execution condition is that the 16R special probability variable big hit game or the 16R normal probability variable big hit game is given a predetermined number of times (20 times in the present embodiment) during the probability changing mode, and a plurality of predetermined types. This is based on the condition that a game effect has been executed.

  If the determination result in step S122 is affirmative, the sub CPU 31a causes an achievement effect to be executed during the big hit game after the symbol variation game ends (step S123). In step S123, after the achievement effect is finished, the sub CPU 31a displays an achievement image indicating that the achievement effect has been executed on the variable display H2, and indicates that the first stage probability change mode has been set again. The value “1” is set in the mode flag, and the mode transition process is terminated. The achievement image is displayed until the next normal mode is set.

  On the other hand, if the determination result in step S122 is negative, the sub CPU 31a updates the stored contents of the RAM 31c by adding 1 to the number of 16R jackpot games given during the third stage probability change mode (step S124). ), The mode transition process is terminated.

  If the determination result in step S121 is negative (if it is not one of the special figures A, B, and a), the sub CPU 31a designates one of the special figures C, D, c, and d by the special symbol designation command. It is determined whether or not (step S125). If the determination result in step S125 is affirmative, the sub CPU 31a indicates that the chance mode is set after the ending effect of the big hit game (4R probability variable big hit game or 4R non-probable big hit game) given after the symbol variation game ends. The value “4” is set in the mode flag (step S126). In step S126, the sub CPU 31a stores a value “3” indicating that the third-stage probability variation mode has been set in the history flag. When the mode flag is set to “4”, after the mode transition process is completed, the sub CPU 31a executes a process such as displaying a background image corresponding to the chance mode, and transitions the effect mode. When the mode flag is set to “4”, the sub CPU 31a displays a background image corresponding to the value set in the history flag. If the determination result of step S125 is negative, the sub CPU 31a ends the mode transition process as it is.

  On the other hand, when the determination result of step S120 is negative (when the third-stage probability variation mode is not indicated), as shown in FIG. 14, the sub CPU 31a indicates that the mode flag value indicates the chance mode (mode flag). = 4) (step S127). If the determination result is affirmative, the sub CPU 31a determines whether any of the special symbols A, B, and a is specified by the special symbol specifying command (step S128). If the determination result in step S128 is affirmative, the sub CPU 31a refers to the history flag stored in the RAM 31c after the jackpot game ends, and indicates that the stage change probability mode set before the chance mode is set. The value is set in the mode flag (step S129), and the mode transition process is terminated.

  On the other hand, when the determination result of step S128 is negative, the sub CPU 31a determines whether any of the special symbols C, D, c, and d is specified by the special symbol specifying command (step S130). If the determination result is affirmative, the sub CPU 31a ends the mode transition process. If the determination result of step S130 is negative, the sub CPU 31a determines whether or not the operation flag has become “0” (step S131). That is, the sub CPU 31a determines whether or not the application of the entrance rate improvement state has ended. If the determination result is affirmative, the sub CPU 31a sets a value “0” indicating that the normal mode is set in the mode flag (step S132). In addition, the sub CPU 31a resets the number of jackpot games given in the probability variation mode and the history flag.

  On the other hand, when the determination result in step S127 is negative (when the chance mode is not indicated, that is, when the latent mode is indicated), the sub CPU 31a performs a special symbol by a special symbol designation command in the executed symbol variation game. It is determined whether any one of A, B, and a is designated (step S133). That is, it is determined whether or not the big hit symbol combination is displayed in a fixed stop state. If the determination result in step S133 is affirmative, the sub CPU 31a executes the first stage probability change mode after the end of the ending effect of the big hit game (16R special probability variable big hit game or 16R normal probability variable big hit game) given after the symbol fluctuation game ends. A value “1” indicating the setting is set in the mode flag (step S134), and the mode transition process is terminated.

  On the other hand, if the determination result of step S133 is negative, the sub CPU 31a determines whether or not any of the special symbols C, D, c, and d is specified by the special symbol specifying command (step S135). If the determination result in step S135 is affirmative, the sub CPU 31a indicates that the latent mode has been set after the ending effect of the big hit game (4R probability variable big hit game or 4R non-probable big hit game) given after the symbol variation game ends. The value “5” is set in the mode flag (step S136). On the other hand, when the determination result of step S135 is negative, the sub CPU 31a executes a falling lottery (step S137). In step S137, when the probability variation state is given, the winning lottery is won with a probability of 1/20. When the probability variation state is not granted, the winning lottery is won with a probability of 1/10. It is supposed to be. If the determination result of step S137 is affirmative, the sub CPU 31a sets a value “0” indicating that the normal mode is set to the mode flag (step S138). On the other hand, if the determination result of step S137 is negative, the sub CPU 31a ends the mode transition process as it is.

  And in this embodiment, even if it is a case where the same variation pattern is designated, the specific effect content of a symbol variation game is changed for every effect mode. Further, during the probability variation mode, the specific content of the design variation game is changed for each performance stage. Hereinafter, detailed processing for changing specific contents of the production will be described.

  When the sub CPU 31a inputs the variation pattern designation command, the sub CPU 31a determines an effect execution content pattern for specifying the specific effect execution content of the symbol variation game according to the value of the mode flag. The performance execution content pattern is a specific content of the game performance executed within the performance time specified by the variation pattern (such as appearance character, variation speed of decorative design, music, sound effect, lamp light emission pattern, etc.). It is something to identify. As shown in FIG. 15, a plurality of effect execution content patterns are associated with each variation pattern. The performance execution content patterns are classified according to the value of the mode flag. That is, the sub CPU 31a determines an effect execution content pattern from the effect execution content patterns corresponding to the value of the mode flag among the effect execution content patterns corresponding to the designated variation pattern. Then, the sub CPU 31a is configured to execute a game effect related to the symbol variation game based on the designated variation pattern and the determined performance execution content pattern.

  For example, the sub CPU 31a determines and executes the effect execution content pattern PA20 if the mode flag is set to “0” when the big hit effect variation pattern P2 is designated. Further, when the variation pattern P5 for the outlier reach effect is designated, the sub CPU 31a determines and executes the effect execution content pattern PA54 if the mode flag is set to “4”. Even when the same variation pattern is designated during the probability variation mode, the effect execution content pattern selected for each effect stage is different. That is, when the big hit effect variation pattern P2 is designated, if the mode flag is set to “1”, the sub CPU 31a determines and executes the effect execution content pattern PA21. On the other hand, when the variation pattern P2 for the big hit effect is designated and the mode flag is set to “2”, the effect execution content pattern PA22 is determined and executed. Thereby, it is possible to entertain a different game production for each production stage.

  Further, when a variation pattern designation command is input during the chance mode, the type of effect execution content pattern that can be selected for each history flag is changed. For example, when the mode flag is set to “4” and the history flag is set to “2”, when the change pattern P2 is designated, the sub CPU 31a produces the effect execution content pattern PA24, The PB 22 can be selected. Thus, when the chance mode is set, the content of the symbol variation game executed during the chance mode may be changed depending on the stage of the probability change mode set before the chance mode is set. It has become. Therefore, the player can be made aware of the stage of production of the probability change mode before the chance mode is set, and can be reminded.

  Further, for example, when the mode flag is set to “4” and the history flag is set to “1”, when the variation pattern P1 is designated, the sub CPU 31a produces the effect execution content pattern. PA14, PB11, and PC1 can be selected. On the other hand, when the mode flag is set to “4” and the history flag is set to “2”, the sub CPU 31a, when the variation pattern P1 is designated, produces the effect execution content pattern. PA14 and PB12 can be selected. As described above, when the chance mode is set, there is an effect execution content pattern PC1 that can be selected when the history flag is “1” but cannot be selected when the history flag is “2”. For this reason, the player pays attention by the stage of the probability variation mode set before the chance mode. Further, even when the mode is shifted to the chance mode, different game effects can be enjoyed depending on the stage of the probability change mode set before the chance mode, so that it is possible to improve the interest of the game.

  And in this embodiment, when 16R big hit game which transfers to probability change mode is provided, selection effect is performed. Specifically, a selection effect (appearance character selection effect) is executed in a predetermined round game during the 16R special probability variable big hit game or the 16R normal probability variable big hit game. Various game effects (for example, reach effects, etc.) according to the corps (appearance character, in this embodiment, Uesugi army, Sanada army, Date army) selected in this selection effect during the probability change mode and chance mode Is to be executed. In addition, during the probability change mode and the chance mode, a display effect is displayed in which a selection flag set for each corps so that the selected corps can be recognized is displayed on the variable display H2. That is, a display effect according to the selection result is executed. Hereinafter, the processing related to the selection effects and the various game effects performed along with the selection effects will be described.

  First, processing related to the selection effect will be described. This selection effect is executed during the round game effects of the 5th to 6th rounds determined in advance when the 16R special probability variable big hit game or the 16R normal probability variable big hit game is awarded.

  When the sub CPU 31a inputs a round command of the fifth round, the sub CPU 31a specifies options to be presented in the selection effect (that is, selectable corps). Specifically, when a predetermined appearance condition is established, the sub CPU 31a specifies three types of corps (characters), the Uesugi army, the Sanada army, and the Date army, as selectable options. . On the other hand, when the predetermined appearance condition is not satisfied, the sub CPU 31a specifies two types of corps (characters) of the Uesugi army and the Sanada army as selectable options. In the present embodiment, the appearance condition is that a 16R jackpot game is given during the chance mode.

  Then, the sub CPU 31a displays a display image indicating a selectable corps as an option during the round game effect of the fifth round. Then, the sub CPU 31a sets an operation valid period during the round game effect of the sixth round. It is assumed that the corps indicated by the option is selected by operating the effect button 40 and selecting the option within this operation valid period. When the corps is selected, the sub CPU 31a sets and stores a value indicating that the selection flag is set for each corps so as to indicate the selected corps. When “1” is set in the selection flag corresponding to each corps, it indicates that the corps corresponding to the selection flag is not selected, while “2” or more is selected in the selection flag corresponding to each corps. Is set, it indicates that the corps corresponding to the selection flag is selected. When the effect button 40 is not operated within the operation valid period, the sub CPU 31a is assumed to have selected a predetermined option (an option indicating the Uesugi army in the present embodiment).

  When the 16R special probability variable big hit game or the 16R normal probability variable big hit game ends, the sub CPU 31a sets the probability variable mode and displays a selection flag in a display mode corresponding to the selected corps. In the present embodiment, a selection flag is displayed on the variable display H2 for each selectable corps, and it is displayed that the value (level) of the selection flag is 1 before the selection. Indicates that the value (level) of the selection flag is 2 or more. Note that, once selected, it is set as selected until the probability variation mode ends (that is, the selection flag does not become level 1). Further, unless the appearance condition is satisfied, the selection flag corresponding to the Date army is not displayed.

Next, processing related to execution of game effects related to the selected corps (selection result) during the probability change mode will be described.
When the sub CPU 31a determines an effect execution content pattern from a plurality of effect execution content patterns associated with the specified variation pattern during the probability change mode, the type of effect execution content pattern that can be determined according to the value of the selection flag Has been changed.

  Specifically, the sub CPU 31a determines a predetermined variation when “1” to “3” are set as the value of the mode flag (when the one- to three-stage probability variation mode is set). When a pattern is designated, the type of effect execution content pattern is changed according to the value of the selection flag. In the present embodiment, the sub CPU 31a, when “1” to “3” are set as the value of the mode flag and the variation pattern is designated, the type of effect execution content pattern according to the value of the selection flag To change. That is, the type of effect execution content pattern determined according to the corps selected in the selection effect is changed.

  For example, as shown in FIG. 15, when the variation pattern P3 is designated, “2” is set for the selection flag of the Uesugi army, “1” or “3” is set for the selection flag of the Sanada army, and the Date army When “1” or “3” is set in the selection flag, the sub CPU 31a determines an effect execution content pattern from the effect execution content patterns PA31, PA32, and PU3. When the variation pattern P3 is designated, “1” or “3” is set in the selection flag of the Uesugi army, “2” is set in the selection flag of the Sanada army, and “1” is set in the selection flag of the Date army. Alternatively, when “3” is set, the sub CPU 31a determines the effect execution content pattern from the effect execution content patterns PA31, PA32, and PS3. When the variation pattern P3 is designated, the selection flag of the Uesugi army is set to “1” or “3”, the selection flag of the Sanada army is set to “1” or “3”, and the selection flag of the Date army Is set to “2”, the effect execution content pattern is determined from the effect execution content patterns PA31, PA32, and PD3.

  When the variation pattern P3 is designated, “2” is set to the selection flag of the Uesugi army, “2” is set to the selection flag of the Sanada army, and “1” or “3” is set to the selection flag of the Date army. Is set, the sub CPU 31a determines an effect execution content pattern from the effect execution content patterns PA31, PA32, PU3, and PS3. When the variation pattern P2 is designated, “1” or “3” is set in the selection flag of the Uesugi army, “2” is set in the selection flag of the Sanada army, and “2” is set in the selection flag of the Date army. Is set, the sub CPU 31a determines an effect execution content pattern from the effect execution content patterns PA31, PA32, PS3, and PD3. When the variation pattern P3 is designated, “2” is set in the selection flag of the Uesugi army, “1” or “3” is set in the selection flag of the Sanada army, and “2” is set in the selection flag of the Date army. Is set, the sub CPU 31a determines an effect execution content pattern from the effect execution content patterns PA31, PA32, PU3, and PD3. Similarly, when the variation pattern P3 is designated, “2” is set for the selection flag for the Uesugi army, “2” is set for the selection flag for the Sanada army, and “2” is set for the selection flag for the Date army. In this case, the sub CPU 31a determines the effect execution content pattern from the effect execution content patterns PA31, PA32, PU3, PS3, and PD3.

  Even if the variation pattern P3 is designated and any of the performance execution content patterns PU3, PS3, and PD3 can be selected, the sub CPU 31a only provides the 16R jackpot game and provides the performance execution content pattern PA32. , PU3, PS3, PD3 are to be selected. That is, the sub CPU 31a selects the effect execution content pattern PA31 when the variation pattern P3 is designated and any of the effect execution content patterns PU3, PS3, and PD3 can be selected, and the 4R jackpot game is given. It is supposed to be.

  In addition, the production execution contents patterns PA31, PA32, PU3, PS3, and PD3 have the same production contents up to the middle, but have different last contents and display results. Specifically, when a symbol variation game is executed based on the selected performance execution content pattern PA31 when a 4R jackpot game is awarded, the symbol combination suggesting the probability change is displayed, defeating the confrontation with the enemy character. The production contents indicate that the probability variation mode ends. When the 16R jackpot game is awarded, if the symbol variation game is executed based on the selectable performance execution content pattern PA32, the confrontation with the enemy character is won, the symbol combination of the jackpot is displayed, and the jackpot game is given. In addition, the production contents indicate that the probability variation mode continues. When the symbol variation game is executed based on the selectable performance execution content pattern PA6 at the time of loss, the confrontation with the enemy character becomes a draw, the symbol combination of the loss is displayed, and the probability variation mode is continued. The contents are directed.

  When the 16R jackpot game is awarded, if the symbol variation game is executed based on the selectable performance execution content pattern PU3, after the Uesugi army appears, it wins the confrontation with the enemy character, and the symbol combination of the jackpot It is displayed and has the effect contents indicating that the big hit game is given and the probability variation mode is continued. When a 16R jackpot game is awarded, if a symbol variation game is executed based on the selectable performance execution content pattern PS3, after the Sanada army appears, it wins a confrontation with an enemy character, and the symbol combination of the jackpot It is displayed and has the effect contents indicating that the big hit game is given and the probability variation mode is continued. When a 16R jackpot game is awarded and a symbol variation game is executed based on the selectable performance execution content pattern PD3, after the appearance of the Date army, it wins a confrontation with an enemy character and the symbol combination of the jackpot It is displayed and has the effect contents indicating that the big hit game is given and the probability variation mode is continued. As described above, when a corps is selected in the selection effect (when the selection flag is “2”), a game effect in which the selected corps appears is executed. In addition, it is impossible to recognize whether or not a big hit is made halfway through the contents of the performance. Furthermore, when the corps selected in the selection effect appears, it can be recognized that a 16R jackpot game is always given. For this reason, it is possible to make the player pay attention to the selection result of the selection effect, and to pay attention to whether or not the game effect related to the selection result of the selection effect is executed during the reach effect.

  Further, in the present embodiment, when a game effect based on the effect execution content patterns PU3, PS3, and PD3 is executed, a special effect related to the selection result of each selected effect during the 16R special probability variable big hit game effect that is given thereafter. A jackpot game effect (premium jackpot effect) is executed. For example, when a game effect based on the effect execution content pattern PU3 is executed, a premium jackpot effect in which the Uesugi army appears is executed during the 16R special probability variable jackpot game effect given thereafter. Similarly, when a game effect based on the effect execution content pattern PS3 is executed, a premium jackpot effect in which the Sanada army appears is executed during the 16R special probability variable jackpot game effect given thereafter. When a game effect based on the effect execution content pattern PD3 is executed, a premium jackpot effect in which the Date army appears is executed during the 16R special probability variable jackpot game effect given thereafter. As described above, the effect related to the corps selected in the selection effect is executed during the symbol variation game, and the effect related to the corps selected in the selection effect is also executed during the jackpot game effect. It has come to be.

  In the present embodiment, when a game effect based on the effect execution content pattern PU3 is executed, “3” is set in the selection flag corresponding to the Uesugi army. When a game effect based on the effect execution content pattern PS3 is executed, “3” is set in the selection flag corresponding to the Sanada army. When a game effect based on the effect execution content pattern PD3 is executed, “3” is set in the selection flag corresponding to the Date army. That is, when the premium jackpot effect is executed, “3” is set in the selection flag to indicate that. When the selection flag “3” is set, the effect execution content patterns PU3, PS3, and PD3 are not selected thereafter. As a result, other premium jackpot effects are likely to appear and appear only once in the probability variation mode, so that a more special feeling can be given.

  Further, when “4” is set as the value of the mode flag (when the chance mode is set), the sub CPU 31a executes the effect according to the value of the selection flag when the variation pattern is specified. Change the content pattern type. In other words, during the chance mode, the type of effect execution content pattern determined according to the corps selected in the selection effect is changed.

  For example, as shown in FIG. 15, when the variation pattern P3 is designated, “2” is set for the selection flag of the Uesugi army, “1” or “3” is set for the selection flag of the Sanada army, and the Date army When the selection flag is set to “1” or “3”, the sub CPU 31a can select the performance execution content patterns PA34 and PU34. Thus, the contents of the effect of the symbol variation game in the chance mode are changed according to the state of the selection flag set in the probability change mode before the chance mode (that is, the selection result of the selection effect). For this reason, during the chance mode, attention can be paid to the state of the selection flag and the selection result of the selection effect set during the probability variation mode before the chance mode. In addition, since the content of the effect in the chance mode changes depending on the selection result, it is possible to focus more on the selection effect and the selection result, and to improve the interest of the game.

  In addition, when the 16R jackpot game is awarded during the chance mode, the sub CPU 31a assumes that an appearance condition including the Date army as an option in the selection effect is satisfied, and thereafter the Date army is included as an option in the selection effect. It will be. When the 16R jackpot game is awarded, the sub CPU 31a is configured to execute a game effect in which the Date army appears during the jackpot game.

  Furthermore, in the present embodiment, when one of the specific performance execution content patterns PU3, PS3, and PD3 that triggers the value of the selection flag to be “3” is selected, the 16R jackpot game Is given a predetermined number of times (10 times in the present embodiment), which is a mode transition condition to the third stage probability change mode. For this reason, when shifting from the second stage probability change mode to the third stage probability change mode, “3” is set in one of the selection flags, and a 16R jackpot game is awarded 10 times during the probability change mode. It will be.

  Similarly, in the present embodiment, when all of the specific performance execution content patterns PU3, PS3, PD3 that trigger the value of the selection flag to “3” are selected, the 16R jackpot game has been performed a predetermined number of times ( Giving 20 times in the present embodiment is the achievement effect execution condition. For this reason, when the achievement effect is executed, “3” is set to all the selection flags, and the 16R big hit game is awarded 10 times during the probability variation mode.

  In this embodiment, when the 4R jackpot game is awarded and the chance mode is set, the sub CPU 31a stores the values of the selection flags set during the probability change mode. When the 16R jackpot game is awarded in the chance mode and the probability variation mode is set again, the sub CPU 31a resets the stored selection flag values. The number of times of grant is also stored and held as it is. That is, the probability variation mode is restarted in a state before the chance mode is set. On the other hand, the sub CPU 31a deletes the number of times of grant and the value of the selection flag when the normal mode is set.

From the above, the sub CPU 31a of this embodiment serves as a mode setting unit and an effect control unit.
Next, the flow of game effects during the probability variation mode will be described.

  If a 16R jackpot game is awarded during the normal mode or the latent mode, the first stage probability change mode is set after the jackpot game is completed. In this first stage probability change mode, as shown in FIG. 10A, a state of aiming at a castle is displayed as a background image, and the player is made aware that the first stage probability change mode has started. When a 16R jackpot game is awarded during the first stage probability change mode, if the 16R jackpot game is awarded five times during the probability change mode, the second stage probability change mode is set.

  In this second stage probability change mode, as shown in FIG. 10 (b), the state of reaching the castle gate is displayed as a background image to let the player recognize that the second stage probability change mode has started. Since the state of reaching the castle gate is displayed as a background image, it is possible for the player to recognize that the content is continuous from the first stage probability change mode and that the story content is in progress. When a 16R jackpot game is awarded during the second stage probability change mode, if any of the selection flags is set to 3 and the 16R jackpot game is awarded more than 10 times, the third stage Probability mode is set.

  In this third stage probability change mode, as shown in FIG. 10C, the state of reaching the castle is displayed as a background image, and the player is made aware that the third stage probability change mode has started. Since the state of reaching the castle is displayed as a background image, the player can recognize that the content is continuous from the second stage probability change mode and that the story content is in progress. And when 16R jackpot game is awarded during the 3rd stage probability change mode, all selection flags are set to 3, and if 16R jackpot game is awarded more than 20 times, it is achieved during the jackpot game Production is performed. In the achievement effect of the present embodiment, the fallen castle is shown in the effect content. Thereafter, the first stage probability change mode is set again. Thereafter, an image indicating that the achievement effect has been executed is displayed on the variable display H2. For this reason, the player can recognize that one to three stages of probability change modes have been completed through the achievement effect and one story has been completed.

  Thereafter, the chance mode is set through the 4R non-probable big hit game, and the same effect is repeated until the 100 symbol variation game is finished and the normal mode is set without giving the big hit game as it is.

  When the 4R jackpot game is awarded during the probability variation mode, the chance mode is set. At that time, as shown in FIG. 11 (a), the state of withdrawal through the road is displayed as a background image to let the player recognize that it is the chance mode. Further, since the state of withdrawal through the road is displayed as a background image, it is possible for the player to recognize that the content is continuous from the probability change mode and that the story content has been changed.

  In addition, during the chance mode, a notification image indicating the state of each selection flag set before the chance mode is set and the stage of production in the probability variation mode is displayed. Furthermore, the contents of the effect of the symbol variation game are changed in accordance with the state of each selection flag set before the chance mode is set and the effect stage of the probability variation mode.

  In addition, when a 16R jackpot game is awarded during the chance mode, the probability change mode of the production stage set before the chance mode is set is set again, and the game continues from the probability change mode of the production stage. It is like that. In addition, each selection flag that was set before the chance mode is set is maintained as it is, and the contents of the design variation game change according to the state of each selection flag that was set before the chance mode is set It has come to be. In addition, when the 16R jackpot game is awarded during the chance mode, the conditions for the appearance of the Date Army are met, and then the Uesugi Army, the Sanada Army, and the Date Army are selected until the normal mode is set. It comes to be presented as an option.

  As described above, when the probability variation mode is continued, when a predetermined condition is satisfied, the effect stage of the probability variation mode to be set is changed. In addition, since the order in which the probability variation mode is set is determined in advance, the same type of probability variation mode is not repeated and the user is not bored. In addition, when the second stage probability change mode is set, the symbol variation game is executed based on one of the execution execution content patterns PS3, PD3, PU3 determined in advance, and 16R When the big hit game is awarded 10 times or more, the process shifts to the third stage probability change mode. Similarly, when the third stage probability change mode is set, all the symbol variation games are executed based on the predetermined performance execution content patterns PS3, PD3 and PU3, and 16R jackpot game is given 20 times or more. If it is, the achievement effect is executed and the first stage probability change mode is set. For this reason, it can be noted whether or not a specific game effect determined in advance is executed and whether or not a 16R jackpot game is given, and even in the probability change mode, the user is not bored. .

Next, how the selection flag is set will be described.
When a 16R jackpot game is awarded in the normal mode or the latent mode, a selection effect is executed during the jackpot game. In the selection effect executed during the first 16R jackpot game after the normal mode or the latent mode is given, an option indicating the Uesugi army and an option indicating the Sanada army are displayed. By selecting an option using the effect button 40, the player sets “2” to the selection flag corresponding to the army (character) indicated by the selected option. Note that “1” is set in the selection flag corresponding to the army indicated by the option that has not been selected.

  Thereafter, the selection effect is executed every time the 16R jackpot game is awarded in the probability variation mode or the chance mode. Then, a selection flag is set according to the selection result of the selection effect. That is, when an option indicating the army corresponding to the selection flag set to “1” is selected in the selection effect, “2” is set to the selection flag corresponding to the army indicated by the option. It should be noted that when the option indicating the army corresponding to the selection flag for which “2” or “3” is set in the selection effect is selected, the value of the selection flag is not changed.

  In addition, if the 16R jackpot game is awarded during the chance mode, then the conditions for the appearance of the Date army will be satisfied until the normal mode is set. The option which shows and the option which shows the Date army are displayed.

  Further, when “2” is set in the selection flag, a game effect related to the army corresponding to the selection flag may be executed based on the performance execution content patterns PU3, PS3, and PD3 during the probability change mode. The effect execution content patterns PU3, PS3, and PD3 are selected only when the variation pattern P3 is designated and a 16R special probability variable big hit game is awarded. In addition, when the symbol variation game is executed based on the effect execution content patterns PU3, PS3, and PD3, the army corresponding to the selection flag set to “2” appears, and so on. A game effect is executed.

  When the symbol variation game is executed based on the effect execution content patterns PU3, PS3, and PD3, the premium jackpot effect is executed in the jackpot game given thereafter. When the symbol variation game is executed based on the effect execution content patterns PU3, PS3, and PD3, “3” is set in the selection flag indicating that the premium jackpot effect is executed. The setting of “3” in the selection flag (that is, the premium jackpot effect is executed) is included in the condition of the third stage mode transition condition and the achievement effect execution condition.

  In addition, when “2” is set in the selection flag, during the chance mode (probability change suggestion mode), the game effects related to the army corresponding to the selection flag are effect execution content patterns PU14 to PU74, PS14 to PS74, PD14. ~ May be executed based on PD74. In addition, when the symbol variation game is executed based on the effect execution content patterns PU14 to PU74, PS14 to PS74, and PD14 to PD74, selection of the selection effect such as the appearance of the army corresponding to the selection flag set to “2” appears. A game effect related to the result is executed.

  When the chance mode is selected, the value set in each selection flag is maintained until the normal mode is set. Then, when a 16R big hit game is given during the chance mode and the mode is changed to the probability change mode again, the game effect is continuously executed based on the selection flag whose value is maintained. Thus, until the normal mode is set, it is possible to continue the game, assuming that there is a series of flows in the game effect.

As described above in detail, the present embodiment has the following effects.
(1) Even if the mode is once shifted to the probability change suggestion mode, when the 16R jackpot game (probability variation jackpot game) is entered and the mode is changed to the probability change mode, the army is selected with a selection effect executed during the 16R jackpot game. By selecting an option to be shown, a game effect related to the selected option is executed during the probability changing mode. That is, the symbol variation game based on the effect execution content patterns PU3, PS3, and PD3 can be executed according to the state of the selection flag (selection result). For this reason, even if the chance mode is set after the probability change mode is set for a long time, the contents of the probability change mode set when returning are executed during the big hit game at the time of the change to the probability change mode. Depending on the result of the selected effect, the content may be different from the probability variation mode set before the chance mode setting. For this reason, it is possible to cause the player to have more willingness to return to the probability change mode and execute the game. And even when the probability variation mode is set again, the interest of the game can be improved.

  (2) When the mode flag is set to “4”, the sub CPU 31a performs the effect execution content patterns PU14 to PU74, PS14 to PS74, PD14 to the state of the selection flag set before the chance mode is set. The symbol variation game based on PD74 is configured to be executable. That is, even when the mode is shifted to the chance mode, the game effect related to the option selected in the selection effect executed before the chance mode is transferred is executed. For this reason, even when the mode is shifted to the chance mode, it is possible to make it seem to have a connection with the probability variation mode. In other words, even in the chance mode, it is possible to make it seem as if the probable state has not ended yet and to have a willingness to continue the game. Further, even when the mode is shifted to the chance mode, the content of the effect changes depending on the selection result of the selection effect, so that the selection result in the selection effect can be paid more attention.

  (3) As long as either one of the probability change mode and the chance mode is set continuously, there is a possibility that a game effect related to the selection result of the selection effect is executed. That is, unless the normal mode is set, the value of the selection flag is not reset. For this reason, even when the mode changes from the probability mode to the chance mode, or even when the mode changes from the chance mode to the probability mode, the probability mode and the chance mode can seem to have a single relationship. . Thereby, the willingness to continue a game can be given.

  (4) When a 16R jackpot game is awarded during the chance mode, the number of options (Date Army in this embodiment) that can be selected in the selection effect increases. For this reason, even if the probability change mode is set again from the chance mode, by selecting a new increased option, the game can be played in a probability change mode different from that before the chance mode setting, and the player is bored. There is no.

  (5) When a 16R jackpot game is awarded during the chance mode, after the jackpot game is finished, the probability change mode of the production stage set before the chance mode is set is set again. That is, even if the mode is shifted to the chance mode, if the 16R jackpot game is awarded, the probability variation mode continues from the probability variation mode at the stage of production set before the chance mode is set again. Become. As a result, even if the progress of the probability variation mode is interrupted, the probability variation mode is not executed from the first stage. For this reason, even if it shifts to the chance mode, the willingness to win a 16R jackpot game during the chance mode can be improved, and the interest of the game can be enhanced. In addition, the player can be prevented from getting bored during the chance mode. In addition, since the types of probability variation modes are changed in order, attention can be paid to the types of probability variation modes.

  (6) Even when the chance mode is set, the sub CPU 31a displays a notification image that indicates the stage of production of the probability change mode that was set before the chance mode was set. For this reason, even if the mode changes to the probability change mode again, it is possible to easily recognize what stage of the probability change mode is executed, and to maintain the willingness to continue the game during the chance mode. it can. In addition, when a game effect according to the stage of the probability change mode before the chance mode is set during the chance mode, it is possible to predict what kind of game effect will be executed, Can be improved.

  (7) During the chance mode, the game effect is executed according to the effect stage of the probability change mode set before the chance mode is set. It is possible to make it seem that the production continues, and to make it seem that the certain change state is still given. Thereby, even if it becomes a chance mode, a player's tiredness can be suppressed and the willingness to continue a game can be maintained. Further, since the contents of the chance mode change depending on the stage of production of the probability variation mode, a predetermined condition is established during the probability variation mode, and it can be noted how the type of the probability variation mode changes. In addition, since the chance mode is not always the same effect content, it is possible to easily confirm to which probability change mode the player can return again without getting bored of the player.

  (8) The sub CPU 31a performs the production execution content patterns PB11 to PB11 according to the production stage of the probability variation mode set before the chance mode is set during the symbol variation game in which the 16R jackpot game is given during the chance mode. Game effects based on PB13, PB21 to PB23, and PB31 to PB33 are executed. This makes it possible to pay attention to the type of probability change mode that was set before the chance mode was set, and before the chance change mode was set again, the type of probability change mode that was set before the chance mode was set. Can remind you.

  (9) During the chance mode, the sub CPU 31a is in the probability variation mode at a stage (two or three stages in the present embodiment) in which the stage of the probability variation mode set before the chance mode is set is determined in advance. In some cases, the execution of the game effect based on the effect execution content pattern PC1 is restricted. Thereby, since the execution of the game effect based on the effect execution content pattern PC1 is restricted, the game effect based on the effect execution content pattern such as the effect execution content patterns PB12, PB13, PB22, PB23 can be easily made to appear.

  (10) Even in the case of shifting to the chance mode, game effects based on the effect execution content patterns PU14 to PU74, PS14 to PS74, PD14 to PD74 in relation to the selection result of the selection effect executed before the chance mode is set. Is executed during chance mode. For this reason, even when the mode is shifted to the chance mode, it is possible to make it seem to have a connection with the probability variation mode. Further, even in the chance mode in which it is not determined that the probability variation state is given, it is possible to make it seem as if the probability variation state has not yet ended, and to have a willingness to continue the game. Further, even when the mode is shifted to the chance mode, the content of the effect changes depending on the selection result in the selection effect before the chance mode is set.

  (11) When the probability variation mode is set, the sub CPU 31a executes a game effect based on any one of the predetermined effect execution content patterns PU3, PS3 and PD3, and When the 16R jackpot game is given 10 times, the probability change mode is changed from the second stage to the third stage. Further, the sub CPU 31a sets the first stage probability change mode when all of the effect execution content patterns PU3, PS3 and PD3 are selected and the 16R big hit game is given 20 times. Yes.

  As described above, when the probability variation mode is continued, when a predetermined condition is satisfied, the stage (type) of the probability variation mode to be set is changed. For this reason, even if the probability variation mode continues, attention can be paid to whether or not a predetermined condition is satisfied, and it is possible to prevent getting bored. In addition, since the order in which the probability variation mode is set is determined in advance, the same type of probability variation mode is not repeated and the user is not bored. In addition, as the game continues, the game can be performed in different types of probability change modes, so that the probability change mode can be expected to continue for a long time.

  In addition, when a predetermined type of probability change mode is set, when a predetermined specific game effect is executed and a specific type of jackpot game is given a predetermined number of times, The type is changed. For this reason, it can be noted whether or not a specific game effect determined in advance has been executed, and whether or not a specific type of jackpot game is given, and even in the probability variation mode, it can be bored. Absent. Further, since the probability variation mode is changed when the probability variation mode is a predetermined type, it is possible to pay attention to the type of the probability variation mode currently set.

  (12) When the corps is selected in the selection effect, the sub CPU 31a thereafter displays a selection flag so as to indicate the selection result. And even if it is a case where the production stage of probability change mode is changed, sub CPU31a will continue to display the said selection flag as long as probability change mode or chance mode is continuing. That is, the initial value “1” is not set to each selection flag. For this reason, even if the production stage (type) of the probability variation mode is changed, as long as the probability variation mode is continued, the player can feel as a production having a series of flows. That is, the player does not feel that the same thing is repeated, and never gets bored. Further, it can be noted whether or not the selection effect has been executed and what selection has been made in the selection effect.

  (13) When the corps is selected in the selection effect, the sub CPU 31a performs a game effect corresponding to the selected corps during the symbol variation game during the period in which the probability variation mode continues (in this embodiment, , A game effect based on the effect execution content patterns PU3, PS3 and PD3). Thereby, the player can be made to pay more attention to whether or not the selection effect has been executed and what kind of selection has been made. In addition, since a game effect corresponding to the selected army may be executed during the symbol variation game, the interest in the symbol variation game can be improved.

  (14) The order in which the probability variation mode is set is determined in advance, and the production contents are continuously formed over a plurality of probability variation modes to form a story. For this reason, the player never gets bored because the story progresses every time the probability change mode continues and the type changes. In addition, since the same type of probability variation mode is not repeated, the user is not bored. In addition, since the order in which the probability variation mode is set is determined in advance, a player who wants to see all types of probability variation modes may make the player think that the probability variation mode will continue for a long time. it can.

  (15) The effect content specified by the effect execution content pattern PU3, PS3, PD3 selected in relation to the selection result of the selected effect is a case where a 16R special probability variable big hit game is given halfway, or a 4R big hit game It is the same as the content of the effect performed in any case among the cases where is given, or when it is off. That is, the game content related to the selection result of the selection effect can be executed as the content of the effect that cannot be determined whether or not the probability variation mode continues halfway. For this reason, in an important game effect in which it is not possible to determine whether or not the probability variation mode will continue halfway, depending on whether or not the selection effect has been executed and the result of the selection, the content of the subsequent effect will change, so that the player gets bored. In addition, attention can be paid to the selection effect. Further, since the process is executed while the probability change mode is continued, even if the type of the probability change mode is changed, it can be recognized as a series of probability change modes.

  (16) When the 16R special probability variable big hit game is determined, the sub CPU 31a has a game effect related to the selection result of the selected effect rather than the effect execution content pattern PA31 (based on the effect execution content patterns PU3, PS3 and PD3). (Game effect) is easy to execute. As described above, when the game effect related to the selection result is executed as the effect content of the game effect related to the important symbol variation game in which it is not possible to determine whether or not the probability change mode is continued halfway, the 16R special probability change big hit may occur. Can be recognized. For this reason, it can be made to pay attention to whether the game effect relevant to a selection result is performed, and the selection in a selection effect. Therefore, since the contents of the subsequent effects change according to the selection result of the selected effects, the player is not bored and attention can be paid to the selected effects.

  (17) When the selection effect is executed and the corps is selected, the sub CPU 31a corresponds to the selected corps (selection result) when the big hit game is played in the period in which the probability variation mode continues thereafter. The jackpot game effect (premium jackpot effect) is configured to be executable. For this reason, when the jackpot game is awarded while the probability variation mode continues, the premium jackpot effect related to the selected army can be enjoyed, and the selected effect can be interested. In this way, since the contents of the subsequent effects change according to the result of the selection effect, the player is not bored and attention can be paid to the selection in the selection effect.

  (18) When the premium jackpot effect is executed (when the jackpot game effect related to the selection result of the selected effect is executed), the sub CPU 31a sets the selection flag to indicate that the premium jackpot effect is executed. Set the value of “3”. And the selection flag corresponding to every corps (selection result) is displayed as a display image with the set value. Thereby, it can confirm that the big hit game effect relevant to the selection result was performed.

  (19) The sub CPU 31a executes the achievement effect when the premium jackpot effect of all types is executed when the third stage probability change mode is set and the 16R jackpot game is awarded 20 times. Change to the first stage probability change mode. As described above, since it is a condition that all kinds of premium jackpot effects are executed, attention is paid to which corps is selected (selection result). At the same time, it is possible to check the selection flag corresponding to each corps as to what kind of premium jackpot effect has been executed, and it is possible to pay attention and not get bored during the probability change mode. Further, since the mode transition condition needs to be achieved during the probability changing mode, it is possible to make the player think that the probability changing mode is desired to continue.

  (20) The selection effect is set during a 16R jackpot game having a long opening time of the jackpots 28 and 29 among a plurality of types of jackpot games. In this way, since the selection effect is not executed unless the 16R big hit game is being played, it is possible to expect and expect the 16R big hit game to be given during the probability variation mode.

In addition, you may change the said embodiment as follows.
-In the above-mentioned embodiment, when the number of 16R jackpot games is given three times during the first stage probability change mode, a jackpot game effect with special contents may be executed. Then, when the big hit game effect of this special effect content is executed, a new type of option (for example, Date Army) may be added to the option of the selected effect. In this case, attention can be paid to whether or not a predetermined number of jackpot games are awarded during the probability variation mode. Moreover, even if the probability variation mode continues until the predetermined number of jackpot games are awarded, the interest of the game can be improved even if the probability variation mode becomes longer.

In the above embodiment, a special jackpot game effect may be executed during the jackpot game when the stage of the probability variation mode increases.
In the above embodiment, the main CPU 30a outputs a special symbol designation command for designating a special symbol to the sub CPU 31a. However, if the type of jackpot game is designated, it may not be output.

  In the above embodiment, the probability variation mode has a plurality of performance stages, but may not have. In addition, the probability variation mode has three stages of production, but may be changed to any stage. For example, the production stage of the probability variation mode may be two stages or ten stages.

  In the above embodiment, in the probability variation mode, the order in which the production stages are shifted is determined in advance, and the production contents are continuous so as to form a story over a plurality of production stages. It does not have to be decided, and it is not necessary to form a continuous story.

  In the above embodiment, the sub CPU 31a is configured to change and set the type of the probability variation mode to be set when a predetermined mode transition condition is satisfied while the probability variation mode is continued. However, the mode transition condition may be arbitrarily changed. For example, the mode transition condition may be that a predetermined jackpot notice effect is executed and a plurality of jackpot games are given.

  In the above embodiment, the selection flag indicating the selection result of the selection effect is displayed together with the set value, but it is not necessary to display it. Thereby, it can be made more interested in what kind of selection was made.

  In the above embodiment, when returning from chance mode to probability variation mode, the probability variation mode of the production stage set before the transition to chance mode was set, but the first (first stage) probability variation mode is reset. May be. In this way, the player strongly desires that the probability change mode continues without shifting to the chance mode, gives a sense of tension, and can increase the degree of attention to the effect during the probability change mode.

  In the above embodiment, even when the chance mode returns to the probability change mode, the values of the selection flags set during the probability change mode before the chance mode transition are maintained, but all the selection flags are initialized. May be used. In this way, the player strongly desires that the probability change mode continues without shifting to the chance mode, gives a sense of tension, and can increase the degree of attention to the effect during the probability change mode. Moreover, when initializing, the selection flag corresponding to the Date army may not be displayed.

  In the above-described embodiment, the two large winning ports, the upper winning port 28 and the lower winning port 29, are provided. Further, the arrangement of the upper university winning opening 28 and the lower university winning opening 29 may be arbitrarily changed. For example, the upper university winning opening 28 may be arranged on the lower right side of the game board YB.

  In the above embodiment, the selection effect can be selected by the effect button 40, but the selection result may not be selected by the effect button 40. That is, the sub CPU 31a may select.

-In the said embodiment, you may change arbitrarily the kind of choice in selection production. In addition, the types of options that increase due to the appearance condition may be arbitrarily increased.
In the above embodiment, the selection effect is executed during the 16R jackpot game, but may be executed during the probability change mode. Further, the selection effect may be executed only during the 16R special probability variable big hit game, or the selection effect may be executed only during the 4R big hit game.

  In the above embodiment, the value “2” indicating that the selection effect was selected in the selection effect corresponding to the selection result of the selection effect was continuously set until the transition to the normal mode. It may be returned to “1”. For example, if a 16R normal jackpot game is given and the selection flag is not set to “3” (unless the military premium jackpot effect corresponding to the selection flag is executed), the selection flag is initialized. (Selection flag may be set to 1). Similarly, in the selection effect executed during the jackpot game given when the selection flag is not set to “3” (the military premium jackpot effect corresponding to the selection flag is not executed), “2” is selected. When the option indicating the army corresponding to the selection flag for which the option is set is not selected, “1” may be set (initialized) to the selection flag corresponding to the army indicated by the option.

  -In the said embodiment, it is not necessary to perform the premium jackpot game effect relevant to the selection result of a selection effect. Further, it is not necessary to execute the symbol variation game of the effect content (based on the effect execution content patterns PU3, PS3, PD3) related to the selection result of the selection effect.

  In the above embodiment, the sub CPU 31a executes a predetermined reach effect during the probability variation mode, and a condition (appearance condition) for increasing the types of selection effect options when the jackpot game is awarded is established. It is good as a thing.

In the above embodiment, the appearance condition may be more easily established as the production stage (or history flag) in the probability variation mode approaches the upper limit stage (three stages).
In the above embodiment, the sub CPU 31a identifies the content of the jackpot notice that suggests the possibility of a big hit according to the determined execution execution content pattern, the value of each selection flag, and the stage of production in the probability change mode during the probability change mode. May be. Similarly, during the chance mode, the sub CPU 31a may specify the contents of the jackpot notice that suggests the possibility of a big hit according to the determined performance execution content pattern, the value of each selection flag, and the value of the history flag. .

In the above embodiment, when a 16R jackpot game is awarded during the chance mode, the selection effect may not be executed during the jackpot game.
-In the said embodiment, it is not necessary to perform the game effect according to the selection result of the selection effect during chance mode. In other words, the chance mode having the same content may be executed regardless of the selection result.

  In the above embodiment, when the chance mode is set, the selection flag may be initialized. Similarly, when the chance mode is set, the history flag need not be set.

In the above embodiment, when the 16R jackpot game is awarded during the chance mode, the appearance condition is satisfied and the number of options is increased, but it is not necessary to increase it.
In the above embodiment, the appearance condition may be satisfied only when the 16R special probability variable big hit game is given during the chance mode.

  In the above embodiment, the appearance condition may be satisfied when a 16R jackpot game is awarded during the chance mode in which the probability variation state is not given. Thereby, the player can recognize that the 16R big hit game is given during the chance mode in which the probability variation state is not given, and can improve the interest of the game.

In the above-described embodiment, it is not necessary to display a notification image for notifying the effect stage of the probability variation mode before setting the chance mode according to the history flag during the chance mode.
In the above embodiment, during the chance mode, it is not necessary to execute the game effect according to the effect stage of the probability change mode before the chance mode is set.
