Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine in which two types of special symbol variation games are performed.

  2. Description of the Related Art Conventionally, gaming machines have various functions for enhancing the interest of games, and so-called battle type gaming machines have been proposed as an example. In a general battle-type gaming machine, a winning ball is paid out when the probability variation state (so-called probability variation) is given, and the winning ball is not given a probability variation state. The award ball is not paid out. For example, there are two types of jackpots, “2R normal” to which a probability variation state is not assigned and “15R probability variation” to which a probability variation state is imparted, and the ratio at which the jackpot is awarded is 2R normal: 15R probability variation = 2: 8. In this case, a prize ball cannot be obtained when a 2R normal jackpot is awarded. For this reason, the 2R normal jackpot becomes substantially the same gaming state as a state where the jackpot is not won. As a result, even if the jackpot probability is 1/400 in the above case, the substantial jackpot probability is 1/500. In addition to the above-mentioned “2R normal change” and “15R probability change”, when there is a “2R probability change” big hit with a probability variation state, it is possible to win in the order of 2R normal change big hit → 2R normal big hit. Conceivable. However, in the 2R probability variable big hit, the round effect that triggers the payout of the prize ball is executed only twice, so even if the big win is won twice, almost no prize ball can be obtained. That is, even if there are three types of big hits ("2R normal change", "15R probability change", "2R probability change"), it is almost the same as when there are two types of big hits ("2R normal change", "15R probability change"). It becomes a gaming state.

  From the above, the battle-type gaming machine has a difference between the apparent jackpot probability (1/400) and the actual jackpot probability (1/500). Yes. Therefore, there has been proposed a gaming machine in which a plurality of start winning holes are provided on the game board surface and a special symbol variation game in which the performance of the winning ball (number of winning balls) is different for each starting winning hole (for example, , See Patent Document 1). More specifically, in the gaming machine described in Patent Document 1, the start winning port (same start port) for giving the start condition of the first special symbol variation game for varying the first special symbol, and the second special symbol are varied. A start winning opening (variable start opening) for providing a start condition for the second special symbol variation game to be provided is arranged on the game board surface. Then, when the result of the first special symbol variation game or the second special symbol variation game is a big hit, a big hit game having a different profit for each special symbol fluctuation game is given. Specifically, when the result of the first special symbol variation game is a big hit, the big special game in which two round effects are executed is given, while the result of the second special symbol variation game is a big hit. In such a case, a big hit game in which 10 round effects are executed is given.

JP 2007-111334 A ([0185], [0187] to [0197], [0265], [0266], FIG. 3 and the like)

  However, in the gaming machine described in Patent Document 1, the first special symbol variation game can be executed when a player fires a game ball in a normal manner (so-called left-handed). In one special symbol variation game, only a big hit game in which two round effects are executed is awarded, so that almost no prize ball can be obtained. As a result, no matter how many times the first special symbol variation game wins, it is impossible to obtain a prize ball, so that the interest of the game may be reduced and the willingness to continue the game may be reduced.

  The present invention has been made in view of the above-mentioned problems, and the purpose of the present invention is to improve the interest of the game by making it easy to obtain a prize ball when the result of the special symbol variation game is a big hit. It is to provide a gaming machine.

In order to solve the above-mentioned problem, the invention described in claim 1 is characterized in that a first special symbol display means for displaying a first special symbol variation game for varying a plurality of types of first special symbols, and a plurality of types of second symbols. Based on the result of the second special symbol variation game and the second special symbol variation game, the second special symbol variation means for displaying the second special symbol variation game for varying the special symbol, the plurality of types of effect symbols are varied. Effect display means for displaying an effect symbol variation game to be performed; first start means for providing a start condition for the first special symbol variation game by detecting a game ball that has entered; and detecting a game ball that has entered Thus, the second special symbol change game is given a starting condition, and has a second opening / closing means that can be switched between an open state in which a game ball is easily received and a closed state in which no game ball is received. Means, storage means for storing the game balls detected by the first start means and the second start means as start reservation balls for each start means, and paying out a prize ball by detecting the entered game balls And when the result of the first special symbol variation game or the second special symbol variation game is a big win, after the special symbol fluctuation game that has been a big hit, the winning means is provided. In a gaming machine that grants a jackpot game constituted by a round effect that releases the game, the first special symbol variation game is a jackpot when the jackpot game is not executed, triggered by detection of a game ball by the first starting means The jackpot determination is performed to determine whether or not the game is successful, and the jackpot game is not executed, triggered by the detection of the game ball by the second starting means. If the determination result by the jackpot determining means for determining whether or not the second special symbol variation game is a jackpot, and the determination result by the jackpot determination means is a jackpot, after the end of the special symbol variation game, The first jackpot game in which the winning means is released, the second jackpot game in which the winning means has a shorter opening time than the first jackpot game, and the winning means is opened in the second jackpot game. Of the third big hit games with short time, the big hit game determining means for determining which of the big hit games to be given, and when the determination result by the big hit determination means is a big hit, the big hit determination is made after the big hit game ends. High probability state determining means for determining whether or not to provide a high probability state in which the probability that the means is determined to be a big hit is higher than the low probability state, and the jackpot game After the completion of the game, it is determined whether or not to give an entrance rate improvement state for improving the entrance probability of the game ball to the second starting means by switching the opening / closing means from the closed state to the open state. A ball-hitting improvement state determining means; and an effect mode setting means for setting an effect mode of a game effect in the special symbol variation game , wherein the big hit determining means is a second start holding ball corresponding to the second start means. If it is not stored in the hold storage means and the first start hold ball corresponding to the first start means is stored in the hold storage means, the big hit based on the first start hold ball And making a jackpot determination based on the second start hold ball when the second start hold ball is stored in the hold storage means, and the jackpot game decision The means determines to give either the first jackpot game or the second jackpot game when the determination result of the jackpot determination based on the first start holding ball is a jackpot, When the determination result of the jackpot determination based on the second start holding ball is a jackpot, it is determined to give the first jackpot game or the third jackpot game, the high probability state determination means When the jackpot game determining means determines to give the first jackpot game or the third jackpot game , the jackpot game is determined to give the high probability state or the low probability state, and the jackpot game If the determination means has decided to grant the second jackpot gaming, the high probability state decided to grant, said jackpot determination of the determination result based on the first start-up hold ball The probability of assigning the high probability state when hit is the same as the probability of assigning the high probability state when the result of the jackpot determination based on the second starting hold ball is a big hit When the high probability state determination means determines to give the high probability state, the entrance rate improvement state determination means is a period until a predetermined number of special symbol variation games are executed in advance. Or when it is decided to give the entrance rate improvement state until the next jackpot game is given, while the high probability state determination means decides to give the low probability state Until the predetermined number of special symbol variation games are executed, it is determined to give the entrance rate improvement state, and the production mode is given the entrance rate improvement state and the high probability state. Not A normal mode that is sometimes set, a high probability mode that is set when the entrance rate improvement state and the high probability state are provided, and indicates that the high probability state is provided, and the entrance A first high probability suggestion mode, which is a high probability suggestion mode that is set when the rate improvement state is assigned and suggests that the high probability state may be assigned; and the first high probability suggestion The high-probability suggestion mode that can be set at a later stage than the mode, and comprising a second high-probability suggestion mode that is less reliable than the first high-probability suggestion mode, When the result of the first special symbol variation game is a big hit during the normal mode, the effect mode setting means gives the first big hit game and the high probability state to the first special symbol. Is When it is the first specific symbol, the high probability mode or the high probability suggestion mode is set as the effect mode in the special symbol variation game after the next time, while the first special symbol is given by the first jackpot game When the first non-specific symbol to which the low probability state is given, the high probability suggestion mode is set as the effect mode in a special symbol variation game after the next time, and the second probability is set during the high probability mode. When the result of the special symbol variation game is a big hit, the second special symbol is a second specific symbol for the first big hit game to which the first big hit game is given and the high probability state is given. In some cases, the high probability mode is set as the effect mode in the special symbol variation game after the next time, while the second special symbol is The second specific symbol for the third jackpot game to which the high probability state is given and the third jackpot game is given and the low probability state is given. When the symbol is a non-specific symbol, the high probability suggestion mode is set as the effect mode in the next special symbol variation game, and the second high probability suggestion mode or the second high probability suggestion mode is set. When the result of the special symbol variation game is a big hit, and the second special symbol is the second specific symbol for the first big hit game, the high probability mode is changed to the effect in the special symbol variation game after the next time. When the result of the second special symbol variation game is a big hit during the first high probability suggestion mode, the second special symbol becomes the third big hit game. When the second specific symbol for technique or the second non-specific symbol is set, the high probability mode or the second high probability suggestion mode is set as the effect mode in the special symbol variation game after the next time, and the second high symbol When the result of the second special symbol variation game is a big hit during the probability suggestion mode, when the second special symbol is the second specific symbol for the third big hit game or the second non-specific symbol, The gist of the gaming machine is characterized in that the second high probability suggestion mode is set as the effect mode in a special symbol variation game after the next time .

  Therefore, in the invention according to claim 1, the jackpot game determination means is a jackpot when the determination result of the jackpot determination based on the first start holding ball is a jackpot, that is, the result of the first special symbol variation game is a jackpot. If it is determined that the first jackpot game or the second jackpot game is to be granted. On the other hand, the jackpot game determining means is configured to output the first jackpot game when the jackpot determination result based on the second start holding ball is a jackpot, that is, when the result of the second special symbol variation game is a jackpot. Alternatively, it is decided to give the third jackpot game. For this reason, the third jackpot game in which the winning time of the winning means is the shortest, that is, the prize ball is most difficult to be paid out, is not awarded when the result of the first special symbol variation game is a jackpot. . Therefore, when the result of the first special symbol variation game is a big hit, it is possible to reliably obtain a prize ball. Further, the third jackpot game can be awarded when the result of the second special symbol variation game is a big hit, but the second special symbol variation game is a game to the second starting means in the increased entrance rate state. It is started for the first time when the entry of a ball is detected, and the improved entry rate state can be given after the end of the jackpot game in which the winning means is released. Therefore, at the time when the third jackpot game is awarded, there is a high possibility that a prize ball is paid out in the first jackpot game or the second jackpot game given before the third jackpot game. There is a high possibility that the award ball has already been paid out. Therefore, even if the result of the second special symbol variation game is a big hit, the prize ball can be obtained almost certainly. From the above, if the result of the special symbol variation game is a big hit, a winning ball can be obtained almost certainly, so that the interest of the game can be improved and the willingness to continue the game can be given.

  Here, as a suitable effect display means in the present invention, an electric effect display means such as a liquid crystal type, a dot matrix type, an electroluminescence element type, a 7 segment type, a drum type, a belt type, etc. Mechanical effect display means and the like can be mentioned. In particular, it is preferable to use an electric effect display means, and it is particularly preferable to use a liquid crystal type among electric effect display means. If it does in this way, it will become easy to perform a complicated production | presentation in a production | presentation symbol fluctuation game.

  Further, the opening / closing means included in the second starting means can be switched between an open state in which the game ball is easily received and a closed state in which the game ball is not received. In addition, as a specific example of the open state, for example, a state in which the door-like opening / closing means is completely opened can be cited. On the other hand, as a specific example of the closed state, for example, a state in which the door-like opening / closing means is completely closed can be cited.

  Here, when the big hit game is constituted by one round effect, the “opening time of the winning means” means the opening time of the winning means in one round effect. On the other hand, when the big hit game is constituted by a plurality of round effects, the “opening time of the winning means” does not mean the opening time in one round effect, but the open time in all round effects. The sum of Therefore, for example, when the big hit game is composed of 10 round effects, and the opening time in one round effect is 5 seconds, the “opening time of the winning means” is 50 seconds.

  In addition, as a state where the entrance rate is improved, a state in which the probability of entering the game ball into the second starting means is improved by increasing the number of times the opening / closing means is switched from the closed state to the open state, or the opening / closing means is in the open state. For example, a state in which the probability of entering the game ball into the second starting means is improved by extending the time to become.

  In addition, when the second special symbol variation game is started after the first jackpot game or the second jackpot game after the first special symbol variation game is finished, that is, the provision of an improved entrance rate is started. If so, it is better to notify the player to that effect. Similarly, after the third jackpot game after the second special symbol variation game is over and the special symbol variation game to which the entry rate improvement state is given is executed a predetermined number of times, the entrance rate is improved. It is preferable to notify the player that the state assignment is finished. More specifically, when the entry rate improvement state determination unit determines that the entry rate improvement state is given, the first notification effect for informing the start of the second special symbol variation game is executed. In addition, it is preferable to include a notification effect executing means for executing a second notification effect for notifying the start of the first special symbol variation game when the application of the improved entrance rate is completed. In this way, since the player can understand which special symbol variation game should be performed, the interest of the game is further improved. Also, it is difficult to start a special symbol variation game different from the special symbol variation game to be performed. For example, the second special symbol variation game can be prevented from being erroneously started even though the result of the first special symbol variation game is not a big hit. In addition, as the first notification effect and the second notification effect, for example, an effect of notifying the start of the first special symbol variation game or the second special symbol variation game by light emission (lighting / flashing, etc.) of light emitting means such as a lamp, An effect of notifying the start of the first special symbol variation game or the second special symbol variation game by sound (sound effect, etc.) from sound output means such as a speaker, the first special symbol variation game, or the second special symbol variation game An effect of notifying the start by display (characters, symbols, pictures, etc.) of display means such as a symbol display device, an effect of notifying the start of the first special symbol variation game or the second special symbol variation game by the operation of the movable body, etc. Is mentioned.

The effect display means is disposed in the center of the game board as viewed from the player, and one of the first starting means and the second starting means is on the left side of the effect display means as viewed from the player. The other one of the first starting means and the second starting means is arranged on the flow path of the game ball passing through the right side of the effect display means as viewed from the player. Preferably it is .

  In addition, since the possibility that the opening / closing means is switched to the open state is low unless the entrance rate improvement state is given, the second starting means is configured to make it difficult for the game ball to enter. On the other hand, since the first starting means does not have the opening / closing means, the first starting means is configured to make it easier to enter the game ball than the second starting means. For this reason, the player normally launches a game ball aiming at the first starting means first.

Therefore , either one of the first starting means and the second starting means is arranged on the flow path of the game ball passing through the left side of the effect display means, and the other one is arranged on the flow path of the game ball passing through the right side of the effect display means. because you lever, is the player upon firing game ball aimed at first starting means, possibly playing ball to ball entrance to the second start means is reduced on the opposite side of the presentation display means, second There is a higher possibility that the first special symbol variation game will be executed than the special symbol variation game. Thereby, the possibility that the jackpot game that is given first is the first jackpot game or the second jackpot game is high. Therefore, since a large number of prize balls can be expected in the jackpot game that is given first, it is possible to have a willingness to continue the game.

Further, according to the invention described in claim 1, directing the mode of game effects in the special symbol variation game, normal mode, improved ball entrance rate ball entrance rate improving state and a high probability state is set when not granted The high probability mode set when the state and the high probability state are given, or the high probability suggestion mode set when the entrance rate improvement state is given. That is, since there are a plurality of effect modes with different profits, the player has a great expectation for the result of the special symbol variation game, and the interest of the game is further improved. In addition, since the production mode setting means sets the production mode according to the type of the first special symbol or the second special symbol, the production mode is changed to another production mode or the current production mode is maintained. But the fun of gaming will improve.

  Here, as a specific example of the contents of the effect in the effect mode, the effect that the characters ("Yeah!", "Sorry!", Etc.) are displayed on the effect display means, the background color displayed on the effect display means Examples include an effect of changing, an effect of displaying a character on the effect display means, and the like. Furthermore, specific examples of the content of the effect in the effect mode include an effect of generating sound from sound generating means such as a speaker, and an effect of lighting or blinking light emitting means such as a lamp.

In addition, although the content of the production in the production mode is not particularly limited, it is preferable that the content of the production gives a positive image as the production mode is advantageous to the player. For example, in the first aspect of the invention, the normal mode set when neither the entrance rate improvement state nor the high probability state is given is the most unfavorable performance mode for the player, and only the entrance rate improvement state is set. The high-probability suggestion mode that is set when the player is given is a production mode that is more advantageous to the player than the normal mode, and is set when both the entrance rate improvement state and the high-probability state are given. The high probability mode is an effect mode that is more advantageous for the player than the high probability suggestion mode. Therefore, in this case, for example, the effect content in the normal mode is an effect that displays a red robot, the effect content in the high probability suggestion mode is an effect that displays, for example, a silver robot, and the effect content in the high probability mode is, for example, It is preferable that the golden robot is displayed. In this way, there is no sense of incongruity between the contents of the effect in the effect mode and the actual game state, so that the interest of the game is further improved.

Further, according to the invention described in claim 1, high-probability suggested mode, the first high probability suggested mode or reliability high probability state is applied than the first high-probability suggested mode is lower second high probability The suggestion mode is set. Thereby, since the types of effect modes with different profits increase, the player has a greater expectation for the result of the special symbol variation game, and the interest of the game is further improved. In addition, the production mode setting means sets the high probability suggestion mode according to the type of the first special symbol or the second special symbol, so that the production mode can be changed to another production mode or the current production mode is maintained. This also improves the fun of gaming.

The content of the effect in the high probability suggestion mode is not particularly limited, but it is preferable that the content of the effect gives a positive image as the high probability suggestion mode is advantageous to the player. For example, in the first aspect of the present invention, the first high probability suggestion mode is an effect mode that is more advantageous for the player than the second high probability suggestion mode. Therefore, in this case, it is preferable that the production content in the second high probability suggestion mode is, for example, an effect in which the character draws with mahjong, and the production content in the first high probability suggestion mode is, for example, an effect in which the character wins with mahjong. . In this way, there is no sense of incongruity between the effect content in the high-probability suggestion mode and the actual game state, so that the interest of the game is further improved.

According to a second aspect of the present invention, in the first aspect , in the first high probability suggestion mode, the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost or lost is first. Until the predetermined number of times is reached, the effect mode setting means sets the first high probability suggestion mode as the effect mode in the special symbol variation game after the next time, and in the first high probability suggestion mode, Alternatively, after the total number of executions of the first special symbol variation game and the second special symbol variation game, which are lost, exceeds the first predetermined number of times, the number of executions of the first special symbol variation game and the second special symbol variation game is The first special symbol variation game or the second special symbol variation game that becomes a loser reach before reaching the second predetermined number of times greater than the first predetermined number of times. Is executed, the effect mode setting means sets the second high probability suggestion mode as the effect mode in the special symbol variation game after the next time, and the first high probability suggestion mode is lost. When the total number of executions of the 1 special symbol variation game and the second special symbol variation game exceeds the second predetermined number of times, the effect mode setting means sets the second high probability suggestion mode in the special symbol variation game after the next time. The gist is to set the production mode.

Therefore, according to the second aspect of the present invention, the results of the first special symbol variation game and the second special symbol variation game are less likely to be a big hit during the first high probability suggestion mode, and the first special symbol variation game and the first special variation game When the total number of executions of the 2 special symbol variation game exceeds the first predetermined number, the production mode setting means shifts to the second high probability suggestion mode that is disadvantageous to the player than the first high probability suggestion mode (falls). Let As a result, the player becomes discouraged when the mode is shifted to the second high probability suggestion mode. Therefore, if the player subsequently shifts to the production mode that is advantageous to the player, the player's joy increases. Therefore, the interest of the game is further improved.

According to a third aspect of the present invention, in the first or second aspect , the total number of executions of the first special symbol variation game and the second special symbol variation game, which are lost or lost, is determined by the production mode setting means. The addition is started from the time when the high probability suggestion mode is set. In the second high probability suggestion mode, the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost or lost reach is the first. 3 Until the predetermined number of times is reached, the effect mode setting means sets the second high probability suggestion mode as the effect mode in a special symbol variation game after the next time, and during the second high probability suggestion mode, The total number of executions of the first special symbol variation game and the second special symbol variation game that will be lost or lost will exceed the third predetermined number of times. If the presentation mode setting means, and its gist to set the normal mode as the presentation mode in the special symbol variation game next time.

Therefore, according to the third aspect of the present invention, the results of the first special symbol variation game and the second special symbol variation game are less likely to be a big hit during the second high probability suggestion mode. When the total number of executions of the 2 special symbol variation game exceeds the third predetermined number of times, the production mode setting means shifts (falls) to the normal mode which is more disadvantageous to the player than the second high probability suggestion mode. Accordingly, the player becomes discouraged when the mode is changed to the normal mode. Therefore, if the mode is changed to an effect mode that is advantageous to the player later, the player's joy is increased. Therefore, the interest of the game is further improved.

As described in detail above, according to the first aspect of the present invention, the game can be improved by making it easier to obtain a prize ball when the result of the special symbol variation game is a big hit. Machine can be provided .

Hereinafter, an embodiment in which a gaming machine of the present invention is embodied in a pachinko machine 10 will be described with reference to the drawings.
(1) Schematic configuration of the entire pachinko machine 10

  FIG. 1 schematically shows the surface side of the pachinko machine 10. The pachinko machine 10 includes a vertical rectangular outer frame 11 that forms an outer shell of the machine body. On the front side of the opening of the outer frame 11, a vertical rectangular middle frame 12 constituting the airframe is assembled so as to be openable and detachable. Further, a front frame 14 is assembled on the front side of the middle frame 12 so as to be opened and closed in a laterally open state. The front frame 14 has a structure in which an upper ball tray 15 is integrally assembled below the window 14a while having a window 14a at the center. A glass frame (not shown) for seeing through and protecting the game board 13 disposed inside the machine is assembled on the back side of the front frame 14. Further, an upper frame lamp 16a, a left frame lamp 16b, and a right frame lamp 16c are provided on the front surface of the front frame 14. Each of the frame lamps 16a to 16c includes a light-emitting body (such as a light-emitting diode) not shown, and is configured by covering the light-emitting body with a lens member. In these frame lamps 16a to 16c, light-emitting decorations such as lighting (flashing) and light-off are performed in accordance with various game effects of the pachinko machine 10 (big hit, reach, etc.).

  A left speaker 17 a is disposed at the upper left portion of the front frame 14, and a right speaker 17 b is disposed at the upper right portion of the front frame 14. The left speaker 17a and the right speaker 17b are for outputting various sounds and performing sound effects. The left speaker 17a and the right speaker 17b are mounted on the back side of the front frame 14, and a plurality of sound emitting holes are formed at locations corresponding to the left speaker 17a and the right speaker 17b on the front side of the front frame 14.

  Further, a lower ball tray 18 is assembled to be openable and closable below the front frame 14 on the front side of the middle frame 12. On the right side of the lower ball tray 18 is mounted an operation handle 19 that is turned by the player when the game ball is launched. Also, on the left side of the lower ball tray 18, a lower speaker 17c that outputs various sounds and produces sound effects is disposed. The lower speaker 17c is attached to the middle frame 12.

  As shown in FIGS. 1 and 2, an inner rail 41 a and an outer rail 41 b are laid in a substantially circular shape on the game board surface 13 a of the game board 13. A game ball launched when the operation handle 19 is operated passes through a launch path generated between the inner rail 41a and the outer rail 41b. In addition, a plurality of game nails 81 and the like projecting from almost the entire area of the game board surface 13a are disposed in the game area, which is the inner area of the inner rail 41a and the outer rail 41b. The game nail 81 is adapted to change the direction of the game ball flowing down in the game area.

  Further, a frame-shaped center accessory 60 having an effect symbol display device 61 as an “effect display means” is attached to a substantially central portion of the game board surface 13a. That is, the effect symbol display device 61 is disposed at the center of the game board 13 as viewed from the player. Although the effect symbol display device 61 of the present embodiment is a liquid crystal type, it may be a dot matrix type, an electroluminescence element type, or a seven segment type symbol display unit. In the effect symbol display device 61, a game effect (display effect) based on a varying image (or image display) is performed. Then, the effect symbol display device 61 displays a symbol combination game (effect symbol variation game) in which a plurality of types of effect symbols E1 are varied in three columns and a symbol combination is derived in relation to the display effect. ing.

The main CPU 31a is connected to the first start port switch SE1, the second start port switch SE2, the count switch SE3, and the gate switch SE5. The main CPU 31a includes the first special symbol display device 51, the second special symbol display device 52, the first special symbol hold display device R, the second special symbol hold display device r, and the normal symbol display device. 53, the normal symbol hold display device F and the round effect number notification device RH are connected. In addition, the main CPU 31a is connected to the ordinary electric accessory solenoid SOL1 and the special prize opening solenoid SOL2.

  As shown in FIG. 5, a main ROM 31b and a main RAM 31c are electrically connected to the main CPU 31a. The main CPU 31a selects various random numbers such as jackpot determination random numbers, jackpot symbol random numbers, reach determination random numbers, variation pattern distribution random numbers used for various lotteries related to the symbol variation game, and lotteries related to the normal symbol variation game. The values of various random numbers such as a normal hit determination random number and a normal symbol distribution random number used in the above are updated every predetermined period. Then, the main CPU 31a sets the updated value in the random number storage area of the main RAM 31c and rewrites the value before the update. Various flags that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set) in the flag storage area of the main RAM 31c. In the timer storage area of the main RAM 31c, various timers that are appropriately rewritten during the operation of the pachinko machine 10 are stored (set). Further, the first start holding ball, the second start holding ball and the normal symbol holding ball are stored in the holding ball storage area of the main RAM 31c. That is, the main RAM 31c has a function as “hold storage means”.

  The big hit determination random number is used when determining whether the first special symbol variation game is a big hit (when determining the first big hit game) and when determining whether the second special symbol variation game is a big hit. This is a random number used in common (when determining the second big hit). The jackpot symbol random number is calculated when the first special symbol B1 is determined when the result of the first special symbol variation game is a big hit, and when the result of the second special symbol variation game is the jackpot. It is a random number used in common when determining the symbol B2. The reach determination random number is a random number used when determining whether or not to execute the reach effect when the result of the first special symbol variation game or the second special symbol variation game is lost (during reach determination). . The variation pattern distribution random number is a random number used when determining the variation pattern for specifying the content of the effect of the game effect in the symbol combination game. The normal hit determination random number is a random number used when determining whether or not the normal symbol variation game is a win (during the normal hit determination). The normal symbol distribution random number is a random number used when determining a normal symbol when the result of the normal symbol variation game is a win.

  The main ROM 31b shown in FIG. 5 stores a variation pattern distribution table (see FIG. 8) in which variation patterns P1 to P13 for symbol combination games are distributed. The variation patterns P1 to P13 are patterns commonly used in the first special symbol variation game and the second special symbol variation game. In each variation pattern P1 to P13, symbols in all the columns are stopped after the symbols (the effect symbols E1) of each column displayed on the effect symbol display device 61 start changing (the symbol combination game is started). This is for specifying the time and contents of the game effect (display effect, light emission effect, sound effect) until the combination game is finished). Each variation pattern P1 to P13 is assigned a variation pattern distribution random number value (100 integers from 0 to 99 in this embodiment). Also, the variation pattern distribution table is allocated with variation patterns P1 to P4 for jackpot presentation, variation patterns P5 to P8 for loss reach presentation, and variation patterns P9 to P13 for loss presentation. Note that the fluctuation patterns P1 to P4 are patterns that serve as a base for the jackpot effect that displays a symbol combination (a jackpot symbol combination) in which the middle symbol stops at the same symbol as the left symbol and the right symbol after reaching the reach effect. ing. Fluctuation patterns P5 to P8 are patterns that serve as a base for a lost reach production that displays a combination of symbols (a combination of lost symbols) in which the middle symbol stops at a different symbol from the left symbol and the right symbol after reaching the reach effect. Yes. Fluctuation patterns P9 to P13 indicate patterns that serve as a base for a loss effect for deriving a symbol combination for a loss (a symbol combination for which a symbol combination that is a big hit or a reach is not derived).

  Further, as shown in FIG. 8, the production time (fluctuation time) of the lost effect, the lost reach effect, and the big hit effect is different for each of the variation patterns P1 to P13. Specifically, the big hit effect is executed for 50 seconds (50000 ms) based on the fluctuation pattern P1, the big hit effect is executed for 52.8 seconds (52800 ms) based on the fluctuation pattern P2, and the big hit effect is executed based on the fluctuation pattern P3. The game is executed for 84.8 seconds (84800 ms), and the big hit effect is executed for 40 seconds (40000 ms) based on the fluctuation pattern P4. Also, the lose reach effect is executed for 51 seconds (51000 ms) based on the fluctuation pattern P5, the lose reach effect is executed for 56 seconds (56000 ms) based on the change pattern P6, and the lose reach effect is executed for 88 seconds based on the change pattern P7. (88000 ms). Furthermore, a lose reach effect is executed for 35 seconds (35000 ms) based on the variation pattern P8, a lose effect is executed for 12 seconds (12000 ms) based on the change pattern P9, and a lose effect is generated for 5.6 seconds based on the change pattern P10. (5600 ms) is executed, the loss effect is executed for 3.5 seconds (3500 ms) based on the fluctuation pattern P11, the loss effect is executed for 13.5 seconds (13500 ms) based on the fluctuation pattern P12, and based on the fluctuation pattern P13. Lost effects are executed for 1.5 seconds (1500 ms).

  Note that the variation patterns P1 to P13 include a continuous variation pattern determined when the continuous variation effect is displayed. More specifically, the continuous variation pattern includes variation patterns P2 to P4 that are continuous variation patterns for the jackpot effect, variation patterns P6 to P8 that are continuous variation patterns for the loss reach effect, and continuous variation patterns for the loss effect. Variation patterns P11 to P13. In addition, in the variation patterns P2 to P4, P6 to P8, and P11 to P13, a variation in which a small variation game with one unit from a variation start to a variation stop as a unit is continuously executed a plurality of times in one symbol variation game. Contents are defined. The small variation game is an effect of causing the effect symbol display device 61 to display an image associated with one of the display stages Lv0 to Lv5.

  Next, various processes related to the special symbol variation game executed by the main CPU 31a (first jackpot determination, second jackpot determination, reach determination, normal hit determination, jackpot symbol, lost symbol, variation pattern determination, etc.) will be described. . The main ROM 31b shown in FIG. 5 stores programs used in the above-described various processes (a jackpot determination program, a jackpot game determination program, a high probability state determination program, and an entry rate improvement state determination program).

  The big hit determination program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “big hit determination means”. That is, the main CPU 31a takes the value of the jackpot determination random number and the jackpot symbol random number that are updated every predetermined period as a result of the establishment of a start winning condition (detection of a game ball by the first start winning device 21). Are obtained from the main RAM 31c, and these values are stored (stored) in a random number storage area of the main RAM 31c. The main CPU 31a determines whether or not the result of the first special symbol variation game is a big hit when the big hit game is not being executed. Specifically, the main CPU 31a compares the jackpot determination random number stored in the random number storage area of the main RAM 31c with the jackpot determination value stored in the main ROM 31b immediately before the start of the first special symbol variation game. Then, the first big hit determination (big hit lottery) for determining whether or not the first special symbol variation game is successful is performed. In the present embodiment, the numbers that can be taken by the jackpot determination random numbers are set to 0 to 1596 (1597 different integers in total). The jackpot determination value is a predetermined value from numerical values that can be taken by the jackpot determination random number. Then, the main CPU 31a uses the four jackpot determination values (“77”, “399”, “788”, “1234”) shown in FIG. 9 to set the jackpot lottery probability to 4/1597 (= 399). .1 / 25) to determine the first big hit.

  The main CPU 31a shown in FIG. 4 and FIG. 5 is a jackpot determination random number that is updated every predetermined period triggered by the establishment of the start winning condition (the detection of the game ball by the second start winning device 22). The value and the value of the big hit symbol random number are acquired from the main RAM 31c, and these values are stored (stored) in the random number storage area of the main RAM 31c. The main CPU 31a determines whether or not the result of the second special symbol variation game is a big hit when the big hit game is not being executed. More specifically, the main CPU 31a compares the jackpot determination random value stored in the random number storage area of the main RAM 31c with the jackpot determination value stored in the main ROM 31b immediately before the start of the second special symbol variation game. Then, the second big hit determination (big hit lottery) for determining whether or not the second special symbol variation game is successful is performed. Then, the main CPU 31a uses the four jackpot determination values (“77”, “399”, “788”, “1234”) shown in FIG. 9 to set the jackpot lottery probability to 4/1597 (= 399). The second big hit determination is performed as 1/25). That is, the main CPU 31a makes a jackpot determination with the same lottery probability regardless of whether the game is the first special symbol variation game or the second special symbol variation game.

  The main CPU 31a shown in FIG. 4 and FIG. 5 is a case where the second start reservation ball corresponding to the second start winning device 22 is not stored in the main RAM 31c, and When the corresponding first start hold ball is stored in the main RAM 31c, the first big hit determination is performed based on the first start hold ball. On the other hand, if the second start hold ball is stored in the main RAM 31c, the main CPU 31a is based on the second start hold ball regardless of whether or not the first start hold ball is stored in the main RAM 31c. The second jackpot determination is performed. In other words, the main CPU 31a preferentially executes the second special symbol variation game when both the first start holding ball and the second start holding ball are stored in the main RAM 31c.

  When the determination result of the first jackpot determination is negative (the value of the random number for the jackpot determination and the jackpot determination value do not match), the main CPU 31a shown in FIGS. 4 and 5 determines the lost gaming state. In the lost game state, the special winning device 23 is maintained in a closed state in which no game ball is received, which is disadvantageous to the player. Then, the main CPU 31a determines the first special symbol B1 to be a symbol (lost symbol Z) specified by the symbol number [0]. Further, the main CPU 31a stores the data corresponding to the determined first special symbol B1 in the main RAM 31c until the processing related to the next symbol variation game is performed.

  Similarly, when the determination result of the second big hit determination is negative (the value of the big hit determination random number and the big hit determination value do not match), the main CPU 31a determines the lost gaming state. Then, the main CPU 31a determines the second special symbol B2 to be the symbol (lost symbol z) specified by the symbol number [0]. Further, the main CPU 31a stores the data corresponding to the determined second special symbol B2 in the main RAM 31c until the processing related to the next symbol variation game is performed.

  When the lost game state is determined, the main CPU 31a shown in FIGS. 4 and 5 compares the reach determination random number value read from the main RAM 31c with the reach determination value stored in the main ROM 31b. Then, reach determination is made as to whether or not to execute lose reach. In the present embodiment, the numerical values that can be taken by the random numbers for reach determination are 0 to 180 (a total of 181 types of integers). The reach determination value is a value determined in advance from numerical values that can be taken by the reach determination random number.

  Note that the reach determination value differs depending on the gaming state, the first start holding ball, and the value of a special symbol variation processing flag described later. As shown in FIG. 10A, when the special symbol processing flag is “00H” and the probability variation state and the entrance rate improvement state described later are not given, the main CPU 31a holds the first start suspension. Regardless of the sphere, reach determination is performed using 30 reach determination values with a reach lottery probability of 30/181. Further, when the special symbol variation processing flag is “00H”, the probability variation state and the entrance rate improvement state are not given, and the first start holding ball is “0” or “1”, the main The CPU 31a performs reach determination using 23 reach determination values with a reach lottery probability of 23/181. In addition, when the special symbol variation processing flag is “00H”, the probability variation state and the entrance rate improvement state are not given, and the first start holding ball is “2”, the main CPU 31a has ten pieces. Using the reach determination value, reach determination is performed with a reach lottery probability of 10/181. Further, when the special symbol variation processing flag is “00H”, the probability variation state and the entrance rate improvement state are not given, and the first start holding ball is “3”, the main CPU 31a has two Using the reach determination value, reach determination is performed by setting the reach lottery probability to 2/181. That is, the greater the number of first starting reserved balls, the lower the reach lottery probability. Therefore, when the number of first start reserved balls is large, the first special symbol variation game that is held can be quickly digested. In other words, the smaller the number of first start-reserved balls, the higher the reach lottery probability. Therefore, when the number of first starting reserved balls is small, the probability that the reach effect is executed and the variation time is lengthened is increased, so that the first special symbol variation game is not easily interrupted. When the special symbol variation processing flag is “00H” and the entry rate improvement state is given, the main CPU 31a determines the lottery probability of the first big hit determination and the second big hit determination and the first start hold. Regardless of the ball, reach determination is performed with a reach lottery probability of 0/181. In this case, the main CPU 31a does not make an affirmative determination on reach determination. Note that the second special symbol B2 is a symbol classified into the specific symbol d, and immediately ends the application of the entrance rate improvement state and returns to the normal mode described later, and only the probability variation state is provided. In this case, the main CPU 31a performs reach determination using 30 reach determination values with a reach lottery probability of 30/181. In this case, the lottery probability of reach determination is the highest, which suggests the provision of a probability variation state.

  Further, the reach determination value differs depending on the gaming state, the value of the first start holding ball and the special symbol variation processing flag. As shown in FIG. 10B, when the special symbol variation processing flag is “01H” and the probability variation state and the entrance rate improvement state are not given, the main CPU 31a sets the reach lottery probability to 181. Reach determination is performed with 0 of minutes. In this case, the main CPU 31a does not make an affirmative determination on reach determination. When the special symbol variation processing flag is “01H” and the entrance rate improvement state is given, but the probability variation state is not given, the main CPU 31a sets the reach lottery probability to 16/181. And reach determination. Further, when the special symbol variation processing flag is “01H” and the probability variation state and the entrance rate improvement state are given, the main CPU 31a performs the reach determination with the reach lottery probability set to 8/181.

  When the determination result of the reach determination is affirmative (the reach determination random number value and the reach determination value match), the main CPU 31a shown in FIGS. 4 and 5 determines the lose reach. If the determination result of reach determination is negative (the reach determination random number value and the reach determination value do not match), the main CPU 31a determines a loss (a loss without a reach).

  On the other hand, when the determination result of the first big hit determination is affirmative (the value of the big hit determination random number matches the big hit determination value), the main CPU 31a determines the big hit. When the big win is determined, the main CPU 31a determines the first special symbol B1, which is a symbol related to the stop symbol (the effect symbol E1) derived in the symbol combination game on the effect symbol display device 61. . Specifically, the first special symbol B1 specified by any one of symbol numbers “1” to “39” is determined based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM 31c. To do. Then, the main CPU 31a stores the data corresponding to the determined first special symbol B1 in the main RAM 31c until the process related to the next symbol variation game is performed.

  Similarly, when the determination result of the second big hit determination is affirmative (the value of the big hit determination random number matches the big hit determination value), the main CPU 31a shown in FIGS. 4 and 5 determines the big hit. When the big hit is determined, the main CPU 31a determines the second special symbol B2, which is a symbol related to the stop symbol (effect symbol E1) derived in the symbol combination game on the effect symbol display device 61. Specifically, the second special symbol B2 specified by any one of symbol numbers “1” to “19” is determined based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM 31c. To do. Then, the main CPU 31a stores the data corresponding to the determined second special symbol B2 in the main RAM 31c until the process related to the next symbol variation game is performed.

  In the present embodiment, the special symbol (the first special symbol B1 or the above-described one) is determined according to the type of the special symbol variation game (the first special symbol variation game or the second special symbol variation game) to be executed. The type of the second special symbol B2) is different. Specifically, when “00H” is set as the special symbol variation processing flag, the first special classified as one of the specific symbols A, B, the non-specific symbol C, and the lost symbol Z. The design B1 is determined. The special symbol variation processing flag is a flag indicating whether to execute the first special symbol variation game or the second special symbol variation game. The special symbol variation processing flag is set to “00H” when the first special symbol variation game is executed, and is set to “01H” when the second special symbol variation game is executed. Then, as shown in FIG. 11, when the result of the first special symbol variation game is a big hit, the first special symbol B1 classified as the specific symbol A is determined with a probability of 47/100, The first special symbol B1 to be classified is determined with a probability of 30/100, and the first special symbol B1 classified as the non-specific symbol C is determined with a probability of 23/100. On the other hand, when the result of the first special symbol variation game is lost, the first special symbol B1 classified as the lost symbol Z is determined with a probability of 1 (100%).

  In addition, when “01H” is set as the special symbol variation processing flag, the second special symbol B2 classified as one of the specific symbol a, b, d, the non-specific symbol c, and the lost symbol z is It has come to be decided. Then, as shown in FIG. 12, when the result of the second special symbol variation game is a big hit, the second special symbol B2 classified as the specific symbol a is determined with a probability of 69/100, and the specific symbol b is The symbol to be classified is determined with a probability of 6/100, the symbol to be classified into the specific symbol d is determined with a probability of 2/100, and the symbol to be classified into the non-specific symbol c is a probability of 23/100 Determined by On the other hand, when the result of the second special symbol variation game is lost, the second special symbol B2 classified as the lost symbol z is determined with a probability of 1 (100%).

  Then, the main CPU 31a determines any one of the variation patterns P1 to P13 based on the determination results of the first big hit determination, the second big hit determination, and the reach determination. Specifically, when the big hit is determined in the first big hit determination and the second big hit determination, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, the variation pattern distribution. One of the variation patterns P1 to P4 for the big hit effect is determined from the minute table (see FIG. 8). When the lose reach is determined in the reach determination, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, the variation pattern P5 for the lose reach production from the change pattern distribution table. Any one of -P8 is determined. Further, when the loss is determined in the reach determination, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, the variation pattern P9 to P13 for the effect of the loss from the variation pattern distribution table. One of these is determined.

  4 and 5, the main CPU 31a has a variation pattern P3 (continuous) in which the number of executions of the small variation game is six when the determination result by the first big hit determination or the second big hit determination is a big hit. It is easier to determine the variation patterns P2 and P4 (continuous variation pattern) in which the number of times of execution of the small variation game is 7 times (variation pattern) (see FIG. 13C). On the other hand, the main CPU 31a uses the variation patterns P6, P8, and P12 (continuous variation patterns) in which the number of executions of the small variation game is seven when the determination result by the first big hit determination or the second big hit determination is not a big hit. However, it is easy to determine a variation pattern P7 (continuous variation pattern) in which the number of times of execution of the small variation game is five (see FIGS. 13A to 13C). For example, when the variation pattern P12 is determined, seven small variation games (1500 ms) and six intervals (500 ms) are alternately executed (total 13500 ms). The main CPU 31a determines the first big hit determination. When the determination result by the second big hit determination is not a big hit, the fluctuation pattern P11 in which the number of executions of the small variation game is two times or the small variation is smaller than the variation pattern P7 in which the number of executions of the small variation game is five. It is easy to determine the variation pattern P13 in which the number of game executions is one (see FIGS. 13A to 13C). For example, when the variation pattern P11 is determined, effects are executed in the order of small variation game (1500 ms) → interval (500 ms) → small variation game (1500 ms) (3500 ms in total). On the other hand, when the variation pattern P13 is determined, the small variation game (1500 ms) is executed only once (a total of 1500 ms).

  When the main CPU 31a determines the first special symbol B1 and the variation pattern, the main CPU 31a sets (stores) the variation time associated with each variation pattern as a variation timer in the timer storage area of the main RAM 31c. The special symbol display device 51 is caused to start changing the first special symbol B1. Similarly, when the main CPU 31a determines the second special symbol B2 and the variation pattern, the main CPU 31a sets (stores) the variation time associated with each variation pattern as a variation timer in the timer storage area of the main RAM 31c. The special symbol display device 52 is caused to start changing the second special symbol B2.

  When the main CPU 31a shown in FIGS. 4 and 5 instructs the overall control CPU 32a of the overall control board 32 to perform control, a control command or the like is used as a control signal (8-bit signal), and the signal is output to the output port. 35 and the output buffer 36 at a predetermined timing. Specifically, the main CPU 31a first generates a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation, and sets it as a control command (stored in the main RAM 31c). The control command set here is output in the next command output process. Next, the main CPU 31a sets a special symbol designation command for designating the first special symbol B1 or the second special symbol B2 as a control command (stored in the main RAM 31c). The control command set here is output in the next command output process. Further, the main CPU 31a subtracts the variation timer set at the beginning of the variation every interrupt (4 ms). When the fluctuation time associated with the fluctuation pattern elapses (when the fluctuation timer becomes 0 ms), the main CPU 31a determines that the first special symbol B1 is determined if the first special symbol B1 is determined at the start of the fluctuation. If the second special symbol B2 is displayed on the first special symbol display device 51 and the second special symbol B2 is determined at the start of the change, the second special symbol B2 is displayed on the second special symbol display device 52. Also, the main CPU 31a sets (outputs) a symbol stop command (a first symbol stop command, a second symbol stop command) for instructing a symbol stop of each column as a control command in accordance with the passage of the variation time.

  The main CPU 31a shown in FIGS. 4 and 5 reads a read signal (INT signal or Strobe signal) is output via the output port 35 and the output buffer 36.

  The jackpot game determination program is a program for causing the main CPU 31a to function as a “hit game determination means”. In other words, the main CPU 31a, when the big hit determination is made, after the first special symbol variation game or the second special symbol variation game is finished, the first big winning device 23 in which the big winning device 23 is opened, the second One of the big hit games and the third big hit game is determined to be given. Note that the second jackpot game is a jackpot game in which the opening time of the big winning device 23 is shorter than that of the first jackpot game, and the third jackpot game is a release of the big winning device 23 than the second jackpot game. A big hit game with short time. Here, the opening time of the special winning device 23 indicates not the opening time in one round effect but the total opening time in all round effects. In the first jackpot game, one opening effect, 15 round effects, 15 interval effects, and one ending effect are executed. In the second big hit game, one opening effect, seven round effects, seven interval effects, and one ending effect are executed. Furthermore, in the third jackpot game, one opening effect, two round effects, two interval effects, and one ending effect are executed. The opening effect is executed when the big winning device 23 is in the closed state and when the big hit game is started. Each round effect is executed when the grand prize winning device 23 is switched from the closed state to the open state. Each round effect is executed after the grand prize winning device 23 is switched to the open state until it is switched to the closed state. Each interval effect is executed between a plurality of round effects or between a round effect and an ending effect when the grand prize winning device 23 is switched from the open state to the closed state. The ending effect is a case where the big winning device 23 is switched from the open state to the closed state, and when the big hit game is ended (in this embodiment, any one of the 15th, 7th and 2nd interval effects) At the end of).

  The jackpot game is determined according to the type of jackpot symbol (the first special symbol B1 or the second special symbol B2) (see FIGS. 11 and 12). Specifically, the main CPU 31a performs 15 round effects when the jackpot symbol is a symbol classified into the specific symbol A or the specific symbol a, and the probability variation after the jackpot game ends. A 15R probability variable big hit game (first big hit game) to which a state (high probability state) is given is given. In addition, when the big hit symbol is a symbol classified into the specific symbol B, the main CPU 31a executes 7 round effects and gives a 7R probability variable big hit game (to which a probability variation state is given after the big hit game ends) ( 2nd jackpot game) is granted. Further, when the big hit symbol is a symbol classified as the non-specific symbol C, the main CPU 31a executes 15 round effects and is given the normal state (low probability state) after the big hit game is finished. A 15R non-probable big hit game (first big hit game) is awarded. In addition, when the big hit symbol is a symbol classified into the specific symbol b or the specific symbol d, the main CPU 31a executes the two round effects and gives the probability variation state after the big hit game ends. Probability big hit game (third big hit game) is given. In addition, when the big hit symbol is a symbol classified into the non-specific symbol c, the main CPU 31a executes the two round effects, and the 2R non-probability big hit game in which the normal state is given after the big hit game is finished. (3rd big hit game) is given.

  As shown in FIGS. 11 and 12, in the 15R probability variation big hit game, the prescribed number of winnings for one round effect is set to “8”. Further, in the 15R probability variable big hit game, regardless of the game state at the time when the determination result of the first big hit judgment or the second big hit judgment becomes the big hit, the probability variation state is given after the big hit game is finished. It has become.

  Also, in the 15R probable big hit game, the opening time of the opening effect is set to “10000 ms”, the round time (specified time) of the round effect per time is set to “25000 ms”, and the ending time of the ending effect is set. “12000 ms” is set. Each round effect ends when a predetermined number (8) of game balls enter. For this reason, in the 15R probability variable big hit game, the maximum time is “25000 ms”, which is the round time of a round effect per time. In the 15R probability variation big hit game, the interval time of the interval effect executed between round effects is set to “2000 ms”, and the interval time of the interval effect executed between the round effect and the ending effect is set to “1996 ms”. (= 2000 ms-4 ms) ”.

  As shown in FIG. 11, in the 7R probability variable big hit game, the prescribed number of winnings for one round effect is set to “8”. Further, in the 7R probability variable big hit game, the probability variation state is given after the big hit game is finished, regardless of the gaming state at the time when the determination result of the first big hit determination is big hit.

  In the 7R probability variable big hit game, the opening time is set to “10000 ms”, the round time is set to “25000 ms”, and the ending time is set to “12000 ms”. Each round effect ends when a predetermined number (8) of game balls have entered. For this reason, in the 7R probability variation big hit game, the round time “25000 ms” is the maximum time. In the 7R probability variation big hit game, the interval time of the interval effect executed between the round effects is set to “2000 ms”, and the interval time of the interval effect executed between the round effect and the ending effect is set to “1996 ms”. (= 2000 ms-4 ms) ”.

  As shown in FIG. 11, in the 15R non-probable big hit game, the prescribed number of winnings for one round effect is set to “8”. Further, in the 15R non-probability big hit game, the normal state is given after the big hit game is finished regardless of the game state at the time when the determination result of the first big hit judgment is the big hit.

  In the 15R non-probable big hit game, the opening time is set to “10000 ms”, the round time is set to “25000 ms”, and the ending time is set to “12000 ms”. Each round effect ends when a predetermined number (8) of game balls have entered. For this reason, in the 15R uncertain large hit game, the round time “25000 ms” is the maximum time. In the 15R non-probable big hit game, the interval time of the interval effect executed between the round effects is set to “2000 ms”, and the interval time of the interval effect executed between the round effect and the ending effect is “ 1996 ms (= 2000 ms-4 ms) ”.

  As shown in FIG. 12, in the 2R probability variation big hit game, the prescribed number of winnings for one round effect is set to “8”. In the 2R probability variable big hit game, regardless of the game state at the time when the determination result of the second big hit determination is a big hit, the probability variation state is given after the big hit game is finished.

  In the 2R probability variable big hit game, the opening time is set to “700 ms”, the round time is set to “6300 ms”, and the ending time is set to “700 ms”. Each round effect ends when a predetermined number (8) of game balls have entered. For this reason, in the 2R probability variable big hit game, the round time “6300 ms” is the maximum time. In the 2R probability variation big hit game, the interval time of the interval effect executed between the round effects is set to “2000 ms”, and the interval time of the interval effect executed between the round effect and the ending effect is set to “1996 ms”. (= 2000 ms-4 ms) ”.

  As shown in FIG. 12, in the 2R non-probable big hit game, the prescribed winning number for one round effect is set to “8”. Further, in the 2R non-probability big hit game, the normal state is given after the big hit game is finished regardless of the game state at the time when the determination result of the second big hit judgment is the big hit.

  In the 2R non-probability big hit game, the opening time is set to “700 ms”, the round time is set to “6300 ms”, and the ending time is set to “700 ms”. Each round effect ends when a predetermined number (8) of game balls have entered. For this reason, in the 2R non-probable big hit game, the round time “6300 ms” is the maximum time. In the 2R non-probability big hit game, the interval time of the interval effect executed between the round effects is set to “2000 ms”, and the interval time of the interval effect executed between the round effect and the ending effect is “ 1996 ms (= 2000 ms-4 ms) ”. Therefore, the opening time, round time, interval time, and ending time in the 2R non-probable big hit game are the same as the times in the 2R probable big hit game. In addition, the opening mode of the big winning opening door 23a in the 2R non-probability big hit game is the same as the opening mode in the 2R probability changing big hit game. Therefore, it is difficult to visually distinguish the 2R non-probable big hit game from the 2R probable big hit game.

  The main CPU 31a shown in FIGS. 4 and 5 generates an opening designation command for instructing the start of the opening effect after the first symbol stop command or the second symbol stop command is output, and serves as a control command. Output. Next, when the first special symbol B1 or the second special symbol B2 stored in the main RAM 31c is a symbol classified as one of the specific symbols A, C, a, A round designation command for instructing start of the first to fifteenth round effects is output as a control command, and an interval designation command for instructing start of the first to fifteenth interval effects is output as a control command. Further, the main CPU 31a issues a round designation command for instructing the start of the first to seventh round effects when the first special symbol B1 stored in the main RAM 31c is a symbol classified into the specific symbol B. While outputting as a control command, the interval designation command which instruct | indicates the start of the 1st-7th interval effect is output as a control command. Furthermore, the main CPU 31a determines whether the first special symbol B2 is stored in the main RAM 31c when the second special symbol B2 is a symbol classified into one of the specific symbols b and d and the non-specific symbol c. A round designation command for instructing the start of a round effect is output as a control command, and an interval designation command for instructing the start of the first and second interval effects is output as a control command. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending effect as a control command. In this embodiment, when the player operates the operation handle 19, a maximum of 100 gaming balls are fired per minute (in other words, 10 to 11 gaming balls per 6 seconds). On the other hand, in the 2R probable big hit game and the 2R non-probable big hit game, the round time is set to 6.3 seconds (6300 ms), so in the round production per time, 10 to 11 shots fired in 6 seconds Some of the game balls can win the big winning device 23. Therefore, in this embodiment, it is possible to win a prize ball even when a 2R jackpot game is awarded.

  The high probability state determination program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as “high probability state determination means”. That is, the main CPU 31a determines whether to give the probability variation state or the normal state after the end of the big hit game. More specifically, when it is determined that the main CPU 31a is to give the 15R probability variation big hit game, that is, when the first special symbol B1 stored in the main RAM 31c is the specific symbol A, the probability variation state Decide to grant. On the other hand, when it is decided to give the 15R non-probable big hit game, that is, when the first special symbol B1 stored in the main RAM 31c is the non-specific symbol C, it is decided to give the normal state. To do. Further, the main CPU 31a gives a probability variation state when it is decided to give the 7R probability variation big hit game, that is, when the second special symbol B2 stored in the main RAM 31c is the specific symbol B. To decide. Further, when it is determined that the main CPU 31a gives the 2R probability variation big hit game, that is, when the second special symbol B2 stored in the main RAM 31c is the specific symbol b or the specific symbol d, the probability variation state Decide to grant. On the other hand, the main CPU 31a gives the normal state when it is determined to give the 2R non-probable big hit game, that is, when the second special symbol B2 stored in the main RAM 31c is the non-specific symbol c. Decide what to do. The probability that the specific symbol (specific symbol A, B) is determined when the determination result of the first big hit determination is a big hit is 77/100 (= 47/100 + 30/100). Further, the probability that a specific symbol (specific symbols a, b, d) is determined when the determination result of the second big hit determination is a big hit is 77/100 (= 69/100 + 6/100 + 2/100). . Therefore, the probability of assigning a probability variation state when the determination result of the first jackpot determination is a big hit coincides with the probability of providing a probability variation state when the determination result of the second jackpot determination is a big hit. Yes.

  In the present embodiment, whether or not the probability variation state is given when the symbol combinations “222”, “444”, “666”, and “888” are displayed as the jackpot symbol combinations based on the effect symbols E1. It has become impossible to recognize. On the other hand, when “111”, “333”, “555”, “777” is displayed as the jackpot symbol combination by the production symbol E1, it is possible to recognize that the probability variation state is given. . In addition, the probability variation state is given from the end of the jackpot game until 10,000 special symbol variation games are executed, or from the end of the jackpot game until the next jackpot game is awarded. It is like that. In the present embodiment, since the probability variation state is continuously given until 10,000 special symbol variation games are executed, the probability variation state is substantially granted until the next jackpot game is granted. It can be said that.

  When the probability variation state is started in the first special symbol variation game, the main CPU 31a shown in FIG. 4 and FIG. 5 has 36 values shown in FIG. Using the jackpot value (“77”, “399”, “788”, “1234”,... I do. Similarly, when the probability variation state is started in the second special symbol variation game, the main CPU 31a selects 36 jackpot determination values (“77”, (399), “788”, “1234”,...), The second big hit determination is performed with the lottery probability of the big hit being 36/1597 (≈44.36 / 1). That is, the number of jackpot determination values is different between the case where the probability variation state is given and the case where the normal state is given. Specifically, the number of jackpot determination values in the probability variation state is nine times that in the probability variation state.

  The entrance rate improvement state determination program is a program for causing the main CPU 31a shown in FIGS. 4 and 5 to function as an “entrance rate improvement state determination unit”. That is, the main CPU 31a is in a state in which the entrance rate is improved after the end of the big hit game (the 15R probability variable big hit game, the 15R non-variable big hit game, the 7R positive variable big hit game, the 2R positive variable big hit game, and the 2R non-variable big hit game). It is determined whether or not to grant. The main CPU 31a of the present embodiment determines that the entrance rate improvement state is given with a probability of 100% when the big hit game ends. In addition, the entrance rate improvement state is a state in which the entrance probability of the game ball to the second start winning device 22 is improved by switching the open / close blade 22b from the closed state to the open state. Specifically, in the improved entrance rate state, a variation time shortening state for shortening the variation time of the normal symbol in the normal symbol variation game is given, and the hit probability of the normal symbol variation game is high. It is a fluctuating state.

  The main CPU 31a shown in FIGS. 4 and 5 finishes the first special symbol B1 or the second stored in the main RAM 31c after the end of the 15R probability variation big hit game to which the probability variation state is given. When the special symbol B2 is a symbol classified as the specific symbol A or the specific symbol a, a state where the entrance rate is improved (variation time reduction state) is given until the next jackpot game is given ( (See FIGS. 11 and 12). In addition, after the 7R probability variable big hit game to which the probability variation state is given, that is, when the first special symbol stored in the main RAM 31c is a symbol classified into the specific symbol B, the main CPU 31a Until the big hit game is awarded, a state in which the entrance rate is improved (variation time shortened state) is given (see FIG. 11). Further, the main CPU 31a finishes the 15R non-probable big hit game to which the normal state is given, that is, when the first special symbol stored in the main RAM 31c is a symbol classified as the non-specific symbol C. Until the special symbol variation game is executed 100 times (predetermined number of times), the entrance rate improvement state (variation time shortening state) is given (see FIG. 11). In addition, the main CPU 31a, after the end of the 2R probability variation big hit game to which the probability variation state is given, when the second special symbol B2 stored in the main RAM 31c is a symbol classified into the specific symbol b. Until the next jackpot game is awarded, the entry rate improvement state (change time reduction state) is given (see FIG. 12). On the other hand, the main CPU 31a has 100 special symbol fluctuations after the 2R probability variable big hit game is finished and the second special symbol B2 stored in the main RAM 31c is a symbol classified as the specific symbol d. Until the game is executed, a state in which the entrance rate is improved (variation time shortened state) is given (see FIG. 12). In addition, the main CPU 31a performs the special 100 times after the end of the 2R non-probable big hit game and the second special symbol B2 stored in the main RAM 31c is a symbol classified as the non-specific symbol c. Until the symbol variation game is executed, the entrance rate improvement state (variation time shortening state) is given (see FIG. 12).

  When the normal symbol variation game is won in the improved entrance rate, the opening / closing blade 22b opens and closes with an operation pattern different from the normal operation. That is, when the normal symbol variation game is won in the normal state, the open / close blade 22b is opened once and the open state is maintained until 300 ms or 1000 ms (specified time) elapses. On the other hand, when the normal symbol variation game is won when the entrance rate is improved, the opening / closing blade 22b opens three times with an interval (for example, 0.1 seconds) and 1500 ms (specified time) in one opening. It is designed to maintain an open state until the time elapses. That is, when the entrance rate is improved, the number of times that the open / close blade 22b is switched from the closed state to the open state is increased, and the time for the open / close blade 22b to remain open is extended. Thus, the player can operate advantageously. Even before the specified time has elapsed, when a specified number of game balls (for example, 10) have entered, the open / close blade 22b is closed. Similarly, even before the opening / closing blade 22b is opened a predetermined number of times (three times), the opening / closing blade 22b is closed when a predetermined number (for example, 10) of game balls enter. Yes.

The main CPU 31a shown in FIGS. 4 and 5 compares the normal hit determination random number value read from the main RAM 31c with the normal hit determination value stored in the main ROM 31b in the normal symbol variation game. Normal hit judgment is performed. In the present embodiment, the numerical values that can be taken by the random numbers for determining ordinary hits are 0 to 240 (a total of 241 types of integers). In the normal state (when the entrance rate improvement state is not given), the main CPU 31a uses 50 normal hit determination values determined in advance from numerical values that can be taken as the normal hit determination random numbers. The normal winning judgment is performed with the lottery probability of 50/241. When the entrance rate is improved, the main CPU 31a uses the 241 normal hit determination values from among the numbers that can be used as the normal hit determination random numbers, and determines the normal hit determination by setting the winning lottery probability to 240/241. I do.
(2-2) Electrical configuration of overall control board 32

  As shown in FIGS. 4 and 5, the overall control board 32 includes an overall control CPU 32a. The general control CPU 32a is electrically connected to an input buffer 37 for inputting a control signal and a read signal output from the main CPU 31a. Further, an input port 38 is electrically connected to the input buffer 37, and a control signal and a read signal are input to the overall control CPU 32a via the input port 38.

  Further, a general ROM 32b and a general RAM 32c are connected to the general control CPU 32a. The overall control CPU 32a updates the values of various random numbers used for determining the game effect at predetermined intervals. Then, the overall control CPU 32a rewrites the value before update by setting the updated value in the setting area of the overall RAM 32c. For example, the random number storage area of the overall RAM 32c stores a random number for a lost symbol, a random number for a lost symbol, a random number for a lost right symbol, a random number for a jackpot effect symbol, and the like. Various flags that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the flag storage area of the overall RAM 32c. Various timers that are appropriately rewritten during operation of the pachinko machine 10 are stored (set) in the timer storage area of the overall RAM 32c.

  A continuous change effect table T10 (see FIG. 14A) is stored in the general ROM 32b shown in FIG. In the continuous change effect table T10, the display stages Lv0 to Lv3 of the movement destination (at the end of the small fluctuation game) are associated with the display stages Lv0 to Lv3 at the current time (at the start of the small fluctuation game), and each movement In the previous display stage, one or a plurality of effect distribution random numbers are distributed. The distribution of the distribution random numbers for production differs depending on whether the probability variation state (high probability) is given or the normal state (low probability) is given. In the continuous change effect table T10 associated with the variation patterns P11 to P13 for the loss effect, the display stage advances in the case where the probability change state is given than in the case where the normal state is assigned. The distribution random numbers for production are distributed. It should be noted that the production control random number can be taken every predetermined period (every 2 ms) by the overall control CPU 32a so that it can take a numerical value within a predetermined numerical range (in this embodiment, 181 kinds of integers ranging from 0 to 180). ) Is updated by adding 1 to the numerical value. Then, the overall control CPU 32a stores the updated value in the overall RAM 32c as the value of the effect distribution random number, and rewrites the value of the effect distribution random number already stored to change the value of the effect distribution random number. It is designed to update sequentially.

  In the general ROM 32b shown in FIG. 5, a continuous change effect table T11 (see FIG. 14B) is stored. The continuous change effect table T11 stores a plurality of display stage combination patterns t1 to t16 indicating the display stages Lv0 to Lv3 in the first to fourth small variation games. Each display stage combination pattern t1 to t16 is assigned one or a plurality of effect distribution random numbers. The distribution of the distribution random numbers for performance differs depending on whether the probability variation state (high accuracy) or the normal state (low accuracy) is applied. More specifically, when the probability variation state is given, the display step combination pattern that advances the display step is more easily determined in the first to fourth small variation games than when the normal state is given. It has become. On the other hand, when the probability variation state is not given, it is easier to determine the display step combination pattern that does not advance the display step in the first to fourth small variation games than when the probability variation state is given. It has become.

  Next, various processes related to the special symbol variation game executed by the overall control CPU 32a will be described. Note that the general ROM 32b stores a program (effect mode setting program) used for the various processes described above.

  By the way, when the variation pattern designation command is input, the overall control CPU 32a shown in FIGS. 4 and 5 stores the variation pattern designated by the variation pattern designation command in the overall RAM 32c. . When the special symbol designation command is input, the overall control CPU 32a stores the first special symbol B1 or the second special symbol B2 designated by the special symbol designation command in the overall RAM 32c.

  Further, the overall control CPU 32a stops and displays the effect symbol on the effect symbol display device 61 at the end of the symbol combination game based on the first special symbol B1 or the second special symbol B2 stored in the overall RAM 32c. E1 is generated. For example, when the first special symbol B1 stored in the general RAM 32c is a symbol specified by any one of the symbol numbers “1” to “39”, or the second special symbol B1 stored in the general RAM 32c. When the symbol B2 is a symbol specified by any one of symbol numbers “1” to “19”, the variation pattern stored in the overall RAM 32c is any one of the variation patterns P1 to P4 for the jackpot effect. Become one. In this case, the overall control CPU 32a generates an effect symbol E1 (effect symbol left, middle, and right) that is finally stopped by the effect symbol display device 61 so that all columns are of the same type. Specifically, the overall control CPU 32a generates the effect symbol left, the effect symbol, and the effect symbol right (the effect symbols are of the same type) based on the first special symbol B1 or the second special symbol B2. The generated effect symbol E1 (effect symbol left, middle, right) is derived to the effect symbol display device 61 as a final symbol combination. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c.

  More specifically, the overall control CPU 32a shown in FIG. 4 and FIG. 5 stores the first special symbol B1 (the symbol classified into the specific symbol A) specified by the symbol number [7] in the overall RAM 32c. If it is, the jackpot symbol combination (“777” in the present embodiment) that can recognize that the 15R probability variable jackpot game is awarded is determined. In addition, the overall control CPU 32a stores the first special symbol B1 (designated as the specific symbol A) specified by the symbol numbers [1] to [6] in the overall RAM 32c when the overall RAM 32c stores the first special symbol B1. The jackpot symbol combination (in this embodiment, “111”, “333”, “555”) that can recognize that at least the probability variation state is given based on the value of the jackpot effect design random number Or one). Further, the overall control CPU 32a stores the first special symbol B1 specified by the symbol numbers [8] to [20] (the symbol classified as the specific symbol A) in the overall RAM 32c when the overall RAM 32c stores the first special symbol B1. The jackpot symbol combination (“222”, “444”, “666”, “in this embodiment”) that can recognize that a jackpot game of at least 15 rounds is given based on the value of the jackpot effect design random number. 888 ").

  The overall control CPU 32a shown in FIGS. 4 and 5 stores the first special symbol B1 specified by the symbol numbers [21] to [26] (the symbol classified into the specific symbol B) in the overall RAM 32c. The jackpot symbol combination based on the probability variation symbol based on the value of the random number for the jackpot effect symbol stored in the overall RAM 32c (any one of “111”, “333”, and “555” in the present embodiment). Decide). Furthermore, the overall control CPU 32a, when the first special symbol B1 specified by the symbol numbers [27] to [39] (the symbol classified as the non-specific symbol C) is stored in the overall RAM 32c, the overall RAM 32c. Based on the value of the random number for the jackpot effect symbol stored in the box, the symbol combination (one of “222”, “444”, “666”, “888” in this embodiment) based on the normal symbol is selected. decide.

  Further, the overall control CPU 32a, when the second special symbol B2 specified by the symbol number [1] (the symbol classified as the specific symbol a) is stored in the overall RAM 32c, the jackpot symbol combination by the probability variation symbol ("777" in this embodiment) is determined. Furthermore, the overall control CPU 32a determines the second special symbol B2 specified by the symbol numbers [2] to [6] (the symbols classified into the specific symbols b and d) or the symbol numbers [7] to [19]. When the second special symbol B2 specified by (the symbol classified as the non-specific symbol c) is stored in the overall RAM 32c, the probability is determined based on the value of the random number for the big hit effect symbol stored in the overall RAM 32c. A symbol combination (“121”, “343”, “565”, “787” in the present embodiment) that suggests the variation state is determined.

  The first special symbol B1 or the second special symbol B2 stored in the overall RAM 32c is a symbol specified by the symbol number [0], and the variation pattern stored in the overall RAM 32c is the variation for the loss reach effect. In the case of any one of the patterns P5 to P8, the overall control CPU 32a shown in FIGS. 4 and 5 determines the loss reach. In this case, the overall control CPU 32a determines the effect symbols left, middle, and right so that the left column and the right column are the same type of symbols, and the middle column is a different type of symbols from the left and right columns. Specifically, the effect symbol left and the effect symbol right (both effect symbols are the same type) are generated based on the value of the random number for the lost left symbol. Then, based on the value of the random symbol for the losing symbol, the effect symbol is generated. If the value of the random symbol for losing and the value of the random number for the left of the losing symbol (or the value of the random number for losing the right symbol) match, the overall control CPU 32a determines that the symbol in the effect symbol and the effect symbol left (or the effect symbol) The production pattern is generated so that (right) does not match. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c. In the present embodiment, the numbers that can be taken by random numbers for the left symbol for lost, the random number for right for lost, and the random number for middle for lost are 10 integers from 0 to 9, and one numerical value corresponds to each type of symbol. It is attached.

  The first special symbol B1 or the second special symbol B2 stored in the overall RAM 32c is a symbol specified by the symbol number [0], and the variation pattern stored in the overall RAM 32c is the variation pattern for the lost effect. In the case of any one of P9 to P13, the overall control CPU 32a shown in FIGS. 4 and 5 determines the loss. In this case, the overall control CPU 32a generates effect symbols left, middle, and right so that all columns do not become the same type of symbols. Specifically, the production symbol left is generated based on the value of the random symbol for the loss left symbol, the production symbol is generated based on the value of the random number for the middle symbol of the loss, and the production is produced based on the value of the random number for the loss right symbol. Generate the symbol right. If the value of the lost symbol random number and the value of the lost right symbol random match, the overall control CPU 32a generates the effect symbol right so that the effect symbol left does not match the effect symbol right. The overall control CPU 32a stores data corresponding to the generated effect symbol left, the effect symbol, and the effect symbol right in the overall RAM 32c.

  The production mode setting program is a program for causing the overall control CPU 32a to function as “production mode setting means”. In other words, the overall control CPU 32a sets a game effect production mode in the first special symbol variation game and the second special symbol variation game based on various control commands and the number of executions of the special symbol variation game. Yes.

  The production mode includes a normal mode, a probability variation mode (high probability mode), and a probability variation suggestion mode (high probability suggestion mode). The normal mode is an effect mode set when the entrance rate improvement state and the probability variation state are not given. In addition, when the result of the second special symbol variation game is a big hit in the second special symbol B2 classified as the specific symbol d, the provision of the improved entrance rate is finished in 100 games after the big hit. However, the probability variation state is still given. However, in this embodiment, when the result of the second special symbol variation game is a big hit with the second special symbol B2 classified as the specific symbol d, the normal mode is exceptionally set as the effect mode. . The probability variation mode is an effect mode that is set when the entrance rate improvement state and the probability variation state are given, and indicates that the probability variation state is given. The probability variation suggestion mode is an effect mode that is set when the entrance rate improvement state is given, and suggests that there is a possibility that the probability variation state is given after the jackpot game is over. The probability variation suggestion mode includes a first probability variation suggestion mode (first high probability suggestion mode) and a second probability variation suggestion mode (second high probability suggestion mode). The second probability variation suggestion mode is an effect mode that can be set at a later stage than the first probability variation suggestion mode. In addition, since the second probability change suggestion mode is a big hit in the first probability change suggestion mode in the previous stage in most cases, the rendering mode to which the probability variation state is given is lower than the first probability change suggestion mode. It is.

  More specifically, the overall control CPU 32a shown in FIGS. 4 and 5 performs the first special symbol stored in the overall RAM 32c when the result of the first special symbol variation game is a big hit during the normal mode. When B1 is a symbol classified into the specific symbol A or the specific symbol B, the probability variation mode or the first probability variation suggestion mode is set as an effect mode in the next special symbol variation game. Specifically, when the overall control CPU 32a sets the probability variation mode as the effect mode, the first special symbol B1 is specified by the symbol numbers [1] to [7] and [21] to [26]. If it is, “03H” is unconditionally set (stored in the overall RAM 32c) as a mode flag indicating that the effect mode is the probability variation mode. When the overall control CPU 32a sets the probability variation mode as the effect mode, if the first special symbol B1 is a symbol specified by the symbol numbers [8] to [20], if the random number lottery is won, “03H” is set (stored in the overall RAM 32c) as a mode flag indicating that the mode is the probability change mode, and if the random number lottery is not won, the mode flag indicating that the effect mode is the first probability change suggestion mode is set. 01H "is set (stored in the overall RAM 32c). The overall control CPU 32a specifies the first special symbol B1 stored in the overall RAM 32c by the symbol numbers [27] to [39] when the result of the first special symbol variation game is a big hit during the normal mode. When the non-specific symbol C is set, the first certain change suggestion mode is set as an effect mode in the next and subsequent special symbol variation games ("01H" is stored as a mode flag in the overall RAM 32c). Then, the overall control CPU 32a performs control to execute a right-handed notification effect for notifying the start of the second special symbol variation game for a certain period of time. In the right-handed notification effect of the present embodiment, the effect of displaying the characters “right-handed →” on the upper left part of the effect symbol display device 61 is performed.

  Note that when the player makes a right strike during the normal mode and the game ball passes through the gate 25, the opening / closing blade 22b of the second start winning device 22 may be switched to the open state. Then, when the game ball wins the second start winning device 22, the second special symbol variation game is executed. In this case, if the result of the second special symbol variation game is a big hit during the normal mode, the overall control CPU 32a shown in FIGS. 4 and 5 sets the type of the second special symbol B2 stored in the overall RAM 32c. Regardless, the first certainty suggestion mode is set as an effect mode in the next and subsequent special symbol variation games ("01H" is stored in the overall RAM 32c as a mode flag).

  In addition, when the result of the second special symbol variation game is a big hit during the probability variation mode, the overall control CPU 32a determines that the second special symbol B2 is the specific symbol a identified by the symbol number [1]. The probability variation mode is set as the effect mode in the special symbol variation game after the next time (“03H” is stored in the overall RAM 32c as the mode flag). Further, the overall control CPU 32a, when the result of the second special symbol variation game is a big hit during the probability variation mode, the specific symbol b, wherein the second special symbol B2 is identified by the symbol numbers [2] to [5]. When the specific symbol d specified by the symbol number [6] and any one of the non-specific symbols c specified by the symbol numbers [7] to [19], the first probability variation suggestion mode is selected. It is set as an effect mode in the special symbol variation game after the next time ("01H" is stored in the overall RAM 32c as a mode flag).

  If the player makes a left strike during the probability change mode, the game ball may win the first start winning device 21 and the first special symbol variation game may be executed. In this case, the overall control CPU 32a shown in FIGS. 4 and 5 determines that the first special symbol B1 has the symbol numbers [1] to [20] when the result of the first special symbol variation game is a big hit during the probability variation mode. When the specific symbol A specified by the above or the specific symbol B specified by the symbol numbers [21] to [26] is set, the probability variation mode is set as the effect mode in the next special symbol variation game (as a mode flag) "03" is stored in the overall RAM 32c). In addition, the overall control CPU 32a uses the non-specific symbol C in which the first special symbol B1 is identified by the symbol numbers [27] to [39] when the result of the first special symbol variation game is a big hit during the probability variation mode. At a certain time, the first certain change suggestion mode is set as an effect mode in the next and subsequent special symbol variation games ("01H" is stored in the overall RAM 32c as a mode flag).

  Further, the overall control CPU 32a, when the result of the second special symbol variation game is a big hit during the first certainty suggestion mode, when the second special symbol B2 is the specific symbol a specified by the symbol number [1] In addition, the probability variation mode is set as an effect mode in the special symbol variation game after the next time (“03H” is stored in the overall RAM 32c as a mode flag). Further, the overall control CPU 32a, when the result of the second special symbol variation game is a big hit during the first certain change suggestion mode, when the second special symbol B2 is the specific symbol b, d or the non-specific symbol c, The probability variation mode or the second probability variation suggestion mode is set as an effect mode in the next special symbol variation game. More specifically, when the overall control CPU 32a sets the probability variation mode as the effect mode, the specific symbol d or the symbol numbers [7] to [19] in which the second special symbol B2 is specified by the symbol number [6]. “02H” is set (stored in the overall RAM 32c) as a mode flag indicating that the effect mode is the second certainty suggestion mode when the non-specific symbol c is identified by (1). Further, when the overall control CPU 32a sets the probability variation mode as the production mode, if the second special symbol B2 is the specific symbol b specified by the symbol numbers [2] to [5], the overall control CPU 32a may win the random number lottery. A mode flag indicating that the effect mode is the second probability change suggestion mode if “03H” is set (stored in the overall RAM 32c) as a mode flag indicating that the effect mode is the probability change mode and if the random number lottery is not won. “02H” is set as a flag (stored in the overall RAM 32c).

  If the player makes a left strike during the first certainty suggestion mode, the game ball may win the first start winning device 21 and the first special symbol variation game may be executed. In this case, the overall control CPU 32a shown in FIG. 4 and FIG. When the specific symbol A specified by [20] or the specific symbol B specified by symbol numbers [21] to [26], the probability variation mode is set as an effect mode in the next special symbol variation game ( “03H” is stored in the overall RAM 32c) as a mode flag. In addition, the overall control CPU 32a determines that the first special symbol B1 is specified by the symbol numbers [27] to [39] when the result of the first special symbol variation game is a big hit during the first certainty suggestion mode. When the symbol is C, the first certainty suggestion mode is set as an effect mode in the next special symbol variation game ("01H" is stored in the overall RAM 32c as a mode flag).

  In the first certain change suggestion mode, the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost or lost reach reaches the first predetermined number (15 in this embodiment). 4 and FIG. 5, the overall control CPU 32a sets the first certainty suggestion mode as the effect mode in the next and subsequent special symbol variation games (stores “01H” as the mode flag in the overall RAM 32c). Then, when the total number of executions of the first special symbol variation game and the second special symbol variation game that will be lost or lost reach exceeds the first predetermined number of times (in this embodiment, the total number of executions has reached 16 times or more) In this case, when the first special symbol variation game or the second special symbol variation game that is lost is executed), the overall control CPU 32a performs the second certain variation suggestion mode in the special symbol variation game after the next time. The mode is set (mode flag “02H” is stored in the overall RAM 32c) (falling transition). The total number of executions of the first special symbol variation game and the second special symbol variation game that will be lost or lost is started to be added from the time when the first certain change suggestion mode is set by the overall control CPU 32a. ing. Further, in the first certain change suggestion mode, the second predetermined number of times that the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost is greater than the first predetermined number of times (in this embodiment, 40 times). (In this embodiment, when the total number of executions is 41 times or more and when the first special symbol variation game or the second special symbol variation game is executed), the overall control is performed. The CPU 32a sets the second probability change suggestion mode as an effect mode in the next and subsequent special symbol change games (stores “02H” as a mode flag in the overall RAM 32c) (falling transition).

  The overall control CPU 32a shown in FIGS. 4 and 5 specifies the second special symbol B2 by the symbol number [1] when the result of the second special symbol variation game is a big hit during the second probability variation suggestion mode. When it is the specific symbol a, the probability variation mode is set as an effect mode in the special symbol variation game after the next time ("03H" is stored as a mode flag in the overall RAM 32c). Further, the overall control CPU 32a specifies that the second special symbol B2 is specified by the symbol numbers [2] to [5] when the result of the second special symbol variation game is a big hit during the second probability variation suggestion mode. The second certainty suggestion mode when the symbol b, the specific symbol d specified by the symbol number [6], or the non-specific symbol c specified by the symbol numbers [7] to [19] Is set as an effect mode in the special symbol variation game after the next time ("02H" is stored in the overall RAM 32c as a mode flag).

  If the player makes a left strike during the second probability variation suggestion mode, the game ball may win the first start winning device 21 and the first special symbol variation game may be executed. In this case, the overall control CPU 32a shown in FIG. 4 and FIG. 5 determines that the first special symbol B1 is symbol number [1] when the result of the first special symbol variation game is a big hit during the second probability variation suggestion mode. When the specific symbol A specified by ~ [20] or the specific symbol B specified by the symbol numbers [21]-[26], the probability variation mode is set as an effect mode in the next special symbol variation game. ("03H" is stored in the overall RAM 32c as a mode flag). Further, the overall control CPU 32a determines that the first special symbol B1 is specified by the symbol numbers [27] to [39] when the result of the first special symbol variation game is a big hit during the second probability variation suggestion mode. When the symbol is C, random number lottery is performed, and the probability variation mode or the first probability variation suggestion mode is set as an effect mode in the special symbol variation game after the next time ("01H" is stored as a mode flag in the overall RAM 32c).

  In the second probability variation suggestion mode, the first special symbol variation game or the second special symbol variation game, which is a big hit after entering the first certain variation suggestion mode, is not executed, and the game is lost or lost. Until the total number of executions of the 1 special symbol variation game and the second special symbol variation game reaches the third predetermined number (100 times in the present embodiment), the overall control CPU 32a shown in FIGS. The two-probable change suggestion mode is set as an effect mode in the next and subsequent special symbol change games ("02H" is stored as a mode flag in the overall RAM 32c). Then, in the second probability variation suggestion mode, the first special symbol variation game or the second special symbol variation game that becomes a big hit after entering the first certain variation suggestion mode is not executed, and the first or second loss variation is achieved. When the total number of executions of the 1 special symbol variation game and the second special symbol variation game exceeds the third predetermined number of times (in this embodiment, when the total number of executions becomes 101 times or more), the overall control CPU 32 a Based on the change end designation command input from the main CPU 31a, the normal mode is set as an effect mode in a special symbol variation game after the next time (falling transition). Specifically, when the normal mode is set as the effect mode, the overall control CPU 32a sets “00H” as a mode flag indicating that the effect mode is the normal mode (stored in the overall RAM 32c). In the 101st special symbol variation game, when the result of the last special symbol variation game is a big hit with the specific symbol b, the overall control CPU 32a displays “ 03H "is set (stored in the overall RAM 32c). Further, when the result of the special symbol variation game becomes a big hit of 2R on the way, the overall control CPU 32a re-counts the third predetermined number of times from the beginning. The change end designation command is a command output from the main CPU 31a when the provision of the change time reduction state is finished. Then, the overall control CPU 32a performs control for executing a left-handed notification effect for notifying the start of the first special symbol variation game for a certain period of time. In the left-handed notification effect of the present embodiment, the effect of displaying the characters “← left-handed” on the upper right part of the effect symbol display device 61 is performed.

  Further, the overall control CPU 32a, when the first special symbol B1 stored in the overall RAM 32c is the symbol specified by symbol number [7] (the symbol classified as the specific symbol A), A jackpot effect pattern Ep1 of effect contents indicating that a game is given is determined. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep1 in the overall RAM 32c. Furthermore, the overall control CPU 32a determines that the first special symbol B1 stored in the overall RAM 32c is the symbol specified by symbol numbers [1] to [6] (the symbol classified as the specific symbol A). In the 1st to 5th round effects, the grant of 15R probability change big hit game is concealed, and in the sixth round effect, the round promotion effect that notifies the grant of 15R probability change big hit game determines the jackpot effect pattern Ep2 included in the effect content. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep2 in the overall RAM 32c. Further, the overall control CPU 32a determines a random number when the first special symbol B1 stored in the overall RAM 32c is a symbol specified by symbol numbers [8] to [20] (a symbol classified into the specific symbol A). If the lottery is won, the first to fourteenth round effects conceal the provision of 15R probability variation big hit game, and the first probability variation notification effect that informs the 15R probability variation big hit game grant in the fifteenth round performance is included in the production contents The big hit production pattern Ep3 is determined. Furthermore, the overall control CPU 32a determines a random number when the first special symbol B1 stored in the overall RAM 32c is a symbol specified by symbol numbers [8] to [20] (a symbol classified into the specific symbol A). If the lottery is not won, it is concealed whether or not the 15R probability variable big hit game is given in the first to fourteenth round effects, and the possibility that the 15R probability variable big hit game is given in the fifteenth round effect is low. The second certainty change notification effect for notifying the effect determines the jackpot effect pattern Ep5 included in the effect content. Then, the overall control CPU 32a stores the determined big hit effect pattern Ep3 or Ep5 in the overall RAM 32c.

  Also, the overall control CPU 32a shown in FIGS. 4 and 5 determines that the first special symbol B1 stored in the overall RAM 32c is specified by the symbol numbers [21] to [26] (classified as the specific symbol B). In the first to fifth round productions, the 15R probability variation big hit game is concealed, and in the sixth round production, the round promotion failure production that informs the non-grant of 15R probability variation big hit game is produced. The big hit production pattern Ep4 included in is determined. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep4 in the overall RAM 32c. As described above, when the first special symbol B1 is the symbol specified by the symbol numbers [21] to [26] (the symbol classified into the specific symbol B), and the first special symbol B1 is the symbol number [1. ] To [6] (symbols classified into specific symbol A), the first or fifth round effects conceal whether or not a 15R probability variation big hit game is given, It is notified whether or not a 15R probability variation big hit game is given in the round effect. As described above, the first special symbol B1 specified by the symbol numbers [1] to [6] and [21] to [26] is likely to cause misunderstandings and misunderstandings to the player. This makes it difficult for the player to recognize whether or not the jackpot game in which 15 round effects are executed is given until the sixth round effect is started. Become interested.

  The overall control CPU 32a shown in FIGS. 4 and 5 classifies the first special symbol B1 stored in the overall RAM 32c by the symbol numbers [27] to [39] (classified as the non-specific symbol C). In the first to fourteenth round productions, it is concealed whether or not a 15R probability variable big hit game is given, and it is unlikely that a 15R probability variable big hit game is given in the fifteenth round production. The jackpot effect pattern Ep5 included in the contents of the effect is determined as the second probability change notification effect that notifies the effect. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep5 in the overall RAM 32c. As described above, when the first special symbol B1 is a symbol specified by symbol numbers [27] to [39] (a symbol classified as non-specific symbol C), and the first special symbol B1 is symbol number [ In the case of the first special symbol B1 specified by 8] to [20] (the symbol classified as the specific symbol A), it is concealed whether or not the 15R probability variation big hit game is given in the first to fourteenth round effects. Then, in the fifteenth round effect, it is notified whether or not the 15R probability variation big hit game is given. As described above, the first special symbol B1 specified by the symbol numbers [8] to [20] and [27] to [39] is likely to cause misunderstandings and misunderstandings to the player. As a result, the player becomes more interested in the fifteenth round effect because it is difficult to recognize whether or not the probability variation state is given until the fifteenth round effect is started.

  4 and 5, the overall control CPU 32a identifies the second special symbol B2 stored in the overall RAM 32c by the symbol number [1] (the symbol classified as the specific symbol a). If it is, the jackpot effect pattern Ep1 is determined. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep1 in the overall RAM 32c. In this way, when a jackpot symbol combination is displayed in the second special symbol variation game, a 15R probability variation jackpot game is always given. That is, at the end of the second special symbol variation game, it is possible to recognize the presence or absence of a 15R probability variation big hit game. For this reason, it is not necessary to increase the types of the second special symbol B2 classified into the specific symbol a or to make the light emission pattern similar in order to cause misunderstanding or misunderstanding. Therefore, the amount of data can be reduced by using one type of the second special symbol B2 classified as the specific symbol a.

  Also, the overall control CPU 32a shown in FIGS. 4 and 5 determines that the second special symbol B2 stored in the overall RAM 32c is specified by the symbol numbers [2] to [6] (in the specific symbols b and d). The symbol to be classified) or the second special symbol B2 stored in the overall RAM 32c is a symbol identified by symbol numbers [7] to [19] (a symbol classified into the non-specific symbol c) The big hit production pattern Ep6 is determined. Then, the overall control CPU 32a stores the determined jackpot effect pattern Ep6 in the overall RAM 32c. As described above, when the second special symbol B2 is the symbol specified by symbol numbers [2] to [6] (the symbols classified into the specific symbols b and d), and the second special symbol B2 is the symbol number. In the case of the symbol specified by [7] to [19] (the symbol classified as the non-specific symbol c), the presence or absence of the probability variation state is concealed, and it is suggested that the probability variation state is given. Further, as described above, the second special symbol B2 specified by the symbol numbers [2] to [6] and [7] to [11] is likely to cause misunderstandings and misunderstandings to the player. Thereby, since it is difficult for the player to recognize whether or not the probability variation state is given, the game can be continued while expecting the provision of the probability variation state.

  Then, the overall control CPU 32a shown in FIGS. 4 and 5 determines the contents of the effect of the continuous change effect. The continuous change effect is an effect executed in both the first special symbol variation game and the second special symbol variation game. The continuous change effect is a high probability state suggestion effect that is displayed during the first probability change suggestion mode and indicates the possibility that the probability variation state is given. During the normal mode, the probability variation mode, and the second probability variation suggestion mode, only the normal first special symbol variation game or the second special symbol variation game is executed, and the continuous variation effect is performed. It will never be done. That is, the overall control CPU 32a determines whether or not to execute the continuous change effect according to the set effect mode.

  Specifically, the overall control CPU 32a determines that the normal mode, the probability change mode, and the second change mode when the mode flag stored in the overall RAM 32c is any one of “00H”, “02H”, and “03H”. It is determined that any of the certainty suggestion modes is set as the effect mode. On the other hand, when the mode flag stored in the overall RAM 32c is “01H”, the overall control CPU 32a determines that the first certain change suggestion mode is set as the effect mode. In this case, the overall control CPU 32a specifies the display stage of the character SC (see FIG. 3) when the variation patterns P2 to P4, P6 to P8, and P11 to P13 are stored in the overall RAM 32c.

  Next, the overall control CPU 32a checks the variation pattern stored in the overall RAM 32c. Then, when the confirmed variation pattern is the variation pattern P11 to P13 for losing effect, the overall control CPU 32a specifies the number of times the small variation game is executed in the symbol combination game, and executes each small variation game. Specify the display stage in. That is, in this embodiment, the pattern of the small variation game is determined by the overall control CPU 32a. More specifically, as shown in FIG. 13A, the number of executions of the small variation game is determined in advance in the variation patterns P11 to P13 for losing effects. Then, after the first probability variation suggestion mode is started, the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost is the second predetermined number of times (in this embodiment, 40 times). If not reached, the variation patterns P11 to P13 for the lost effect are associated with the continuous change effect table T10 (see FIG. 14A) for specifying the display stage in the small change game.

  Therefore, when determining the display stage of the specified small variation game, the overall control CPU 32a shown in FIGS. 4 and 5 refers to the continuous change effect table T10 and obtains the current display stage and the obtained distribution for effect. Based on the random number, the display stage of the movement destination in each small variation game is determined. Then, the overall control CPU 32a stores data indicating the determined display stage of the movement destination in the overall RAM 32c.

  Further, when the total number of executions of the first special symbol variation game and the second special symbol variation game that are lost reaches the second predetermined number of times (40 times in the present embodiment), it is shown in FIG. As described above, the display stage of each small variation game is determined in advance in the variation pattern P12 for losing effect. Accordingly, when the variation pattern P12 in which the small variation game is executed a plurality of times is stored in the overall RAM 32c, the overall control CPU 32a reduces the display step so as to be the first display step Lv0 that is the most disadvantageous for the player. A display stage combination pattern that shifts the display stage to the previous stage each time the variable game is executed is determined. In other words, when the total number of executions of the first special symbol variation game and the second special symbol variation game since the start of the first probability variation suggestion mode becomes 40, the variation pattern P12 for the lost effect is designated. Sometimes, the display stage of each small variation game is determined without lottery. When the variation pattern P11 or P13 is stored in the overall RAM 32c, the display stage is determined based on the continuous change effect table T10 (see FIG. 14A) as described above. Then, the overall control CPU 32a stores data indicating the determined display stage in the overall RAM 32c.

  Similarly, in the overall control CPU 32a shown in FIGS. 4 and 5, the variation pattern stored in the overall RAM 32c is the continuous variation pattern for the big hit effect (variation patterns P2 to P4) or the loss reach production. In the case of a continuous variation pattern (variation patterns P6 to P8), the number of executions of the small variation game in the symbol combination game is specified, and the display stage at the time of execution of each small variation game is specified. In the present embodiment, when any one of the normal mode, the probability variation mode, and the second probability variation suggestion mode is set as an effect mode (that is, the mode flag stored in the overall RAM 32c is “00H”, When the variation pattern stored in the overall RAM 32c is the variation patterns P2 to P4 and P6 to P8, when the first certain variation suggestion mode is set in the case of “02H” or “03H”) In the same time that the first to sixth small fluctuation games are executed, a reach notice that announces that it will reach reach and a big hit notice that notifies that the result of the special symbol fluctuation game will be a big hit It is executed as a notice effect. If the variation pattern stored in the overall RAM 32c is the variation pattern P2, P4, P6, P8, the reach that is continued in the seventh small variation game when the first certain variation suggestion mode is set. The reach production is executed within the same time as the production. Note that after the reach effect, the same effect is executed regardless of the effect mode that is set.

  Note that, as shown in FIG. 13C, the variation stage P2 to P4 for the big hit effect or the variation patterns P6 to P8 for the lost reach effect include display stages in the first to fourth small variation games. A continuous change effect table T10 (see FIG. 14A) for identification and a continuous change effect table T11 (see FIG. 14B) are associated with each other. In addition, display stages in the fifth to seventh small variation games are set in advance in the variation patterns P2 to P4 for the big hit effect or the variation patterns P6 to P8 for the lose reach effect. In the last round (sixth or seventh round in this embodiment), the display stage is set to approach the final stage (display stage Lv5) regardless of the presence or absence of the probability fluctuation state.

  Therefore, the overall control CPU 32a shown in FIG. 4 and FIG. 5 first determines the current display stage and the obtained effect distribution random number at the start of the first special symbol variation game or the second special symbol variation game. Based on the display stage combination pattern t1 to t16 stored in the continuous change effect table T11 (see FIG. 14B), one display stage combination pattern is selected. More specifically, when the probability variation state (high accuracy) is given, the overall control CPU 32a is in a later display stage where the degree of the positive image is higher than the current display stage each time the small variation game is executed. A display stage combination pattern that is easy to shift is determined. On the other hand, when the probability variation state is not given, that is, when the normal state (low probability) is given, the overall control CPU 32a has a positive image more than the current display stage every time the small variation game is executed. A display stage combination pattern that is easy to shift to a previous display stage with a low degree is determined.

  The overall control CPU 32a shown in FIGS. 4 and 5 displays the display stage Lv1 instead of the specific display stage Lv2 in the previous (third) small variation game (that is, the display stage combination patterns t2 to t2). When any one of t4, t6 to t8, and t10 to t16 is selected), the display stage Lv1 is shifted to the display stage Lv2 or Lv3 of the subsequent stage in the current (fourth) small variation game. To do. On the other hand, the overall control CPU 32a, when the display stage in the last (third) small variation game is the specific display stage Lv2 (that is, when any one of the display stage combination patterns t1, t5, t9 is selected). In addition, it is determined that the display stage Lv2 is maintained in the present (fourth) small variation game.

  As a result, by determining the display stage combination pattern, the display stages in the first to fourth small variation games are collectively determined. Thereafter, the display stages in the fifth to seventh small variation games are determined without lottery (see FIG. 13C). When the display stages in all (first to seventh) small variation games are determined, the overall control CPU 32a shown in FIGS. 4 and 5 stores data indicating all the determined display stages in the overall RAM 32c. To do.

  The overall control CPU 32a first displays the character SC (see FIG. 3) after the end of the first special symbol variation game or the second special symbol variation game based on the variation patterns P6 to P8 for the lost reach effect. Is returned to the display stage Lv0.

  Then, the overall control CPU 32a uses, as control commands, a change pattern designation command for designating a change pattern stored in the overall RAM 32c as a control command. This is output to the lamp control CPU 34a. As a result, the specific content of the game effect executed by the display control board 33 and the sound / lamp control board 34 is comprehensively controlled by the overall control board 32. The overall control CPU 32a outputs an effect mode designation command for designating the effect mode stored in the overall RAM 32c to the display control CPU 33a and the sound / lamp control CPU 34a.

  When the variation patterns stored in the overall RAM 32c are the variation patterns P1 to P4 for the jackpot effect, the overall control CPU 32a shown in FIGS. 4 and 5 stores the jackpot effect pattern stored in the overall RAM 32c. A jackpot effect pattern designation command for designating Ep1 to Ep6 is output as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

  Further, the overall control CPU 32a outputs, to the display control CPU 33a and the sound / lamp control CPU 34a, continuous change effect commands that specify the display mode change mode stored in the overall RAM 32c. The continuous change effect command is output at the same time as the pseudo continuous ultra-short variation pattern designating command for designating the variation time of the small variation game (1.5 seconds in this embodiment). Also, the overall control CPU 32a displays a pseudo-continuous super-shortened variation pattern designation command and a continuous change effect command for designating the display stage of the movement destination in accordance with the execution timing of the small variation game. Are repeatedly output at regular intervals (every 2.0 seconds in this embodiment).

  In the present embodiment, the lengths of the small variation games that are executed a plurality of times in one special symbol variation game (the time from the variation start to the variation stop) are equal. Specifically, in the small variation game other than the last small variation game, the variation time per time is set to 1.5 seconds, and the interval time between the small variation games is 0.5 seconds. When the first start hold ball and the second start hold ball are stored in the main RAM 31c, the interval time between special symbol variation games is also set to 0.5 seconds. Therefore, even if a special symbol variation game in which two small variation games are executed based on the variation pattern P11 is executed once, one small variation game is performed based on the variation pattern P13. Even if the special symbol variation game to be executed is executed twice, it looks the same, so the player can determine which variation pattern the special symbol variation game is being executed on. Disappear. In addition, at the end of the small variation game other than the last small variation game in one special symbol variation game, the symbol combination of the loss caused by the effect symbol E1 is temporarily stopped and displayed. Specifically, each time a small variation game other than the last small variation game is started, the overall control CPU 32a stores the lost left design random number, the lost middle design random number, and the lost random design random number stored in the overall RAM 32c. The effect symbol E1 (effect symbol left, effect symbol right, effect symbol right) is determined on the basis of the random symbol for the lose right symbol. Then, the overall control CPU 32a, based on the variation pattern, the first special symbol B1 or the second special symbol B2 stored in the overall RAM 32c at the start of the last small variation game, produces the production symbol E1 (the production symbol left, the production symbol). Inside, the design symbol right) is determined. Therefore, the overall control CPU 32a designates the effect symbol left designation command for designating the effect symbol left of the effect symbol E1, the effect symbol right designation command for designating the effect symbol right of the effect symbol E1, and the effect symbol of the effect symbol E1. The design symbol designation command to be output is output to the display control CPU 33a when the small variation game ends.

  Further, the determination of the continuous change effect command is performed as follows. That is, the overall control CPU 32a shown in FIGS. 4 and 5 sets (stores in the overall RAM 32c) a display stage flag indicating the type of the display stage associated with the small change game when the small change game is executed. The display stage flag is set to “00H” when it is the display stage Lv0, is set to “01H” when it is the display stage Lv1, is set to “02H” when it is the display stage Lv2, and the display stage Lv3. Is set to “03H”, the display stage Lv4 is set to “04H”, and the display stage Lv5 is set to “05H”. Then, the overall control CPU 32a displays the previously set display stage flag, the tables shown in FIGS. 13A to 13C, the continuous change effect table T10 (see FIG. 14A), and the continuous change effect table T11. The display stage set this time is determined based on (see FIG. 14B), and the determined display stage is set as a display stage flag.

  Next, the overall control CPU 32a determines a continuous change effect command from a continuous change effect command determination table (not shown) based on the previously set display step flag and the currently set display step flag. For example, when the previous display stage flag is “00H” and the current display stage flag is “00H”, a continuous change effect command for designating a change mode for maintaining the display stage Lv0 is determined. When the previous display stage flag is “01H” and the current display stage flag is “00H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv1 to Lv0 is determined. When the previous display stage flag is “02H” and the current display stage flag is “00H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv2 to Lv0 is determined.

  When the previous display stage flag is “00H” and the current display stage flag is “01H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv0 to Lv1 is determined. When the previous display stage flag is “01H” and the current display stage flag is “01H”, a continuous change effect command for designating a change mode for maintaining the display stage Lv1 is determined. When the previous display stage flag is “02H” and the current display stage flag is “01H”, the command for continuous change effect designating the change mode for shifting the display stage from Lv2 to Lv1 is determined. When the previous display stage flag is “03H” and the current display stage flag is “01H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv3 to Lv1 is determined.

  Further, when the previous display stage flag is “01H” and the current display stage flag is “02H”, a command for continuous change effect designating a change mode for shifting the display stage from Lv1 to Lv2 is determined. When the previous display stage flag is “02H” and the current display stage flag is “02H”, the command for continuous change effect designating the change mode for maintaining the display stage Lv2 is determined. When the previous display stage flag is “03H” and the current display stage flag is “02H”, the command for continuous change effect designating the change mode for shifting the display stage from Lv3 to Lv2 is determined.

  When the previous display stage flag is “02H” and the current display stage flag is “03H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv2 to Lv3 is determined. When the previous display stage flag is “03H” and the current display stage flag is “03H”, the command for continuous change effect designating the change mode for maintaining the display stage Lv3 is determined.

  If the previous display stage flag is “03H” and the current display stage flag is “04H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv3 to Lv4 is determined. When the previous display stage flag is “04H” and the current display stage flag is “05H”, a continuous change effect command for designating a change mode for shifting the display stage from Lv4 to Lv5 is determined.

  Further, the overall control CPU 32a shown in FIGS. 4 and 5 outputs an effect symbol left designation command for designating the effect symbol left of the effect symbol E1 to the display control CPU 33a as a control command. Similarly, the overall control CPU 32a sends, to the display control CPU 33a, an effect symbol right designation command for designating the effect symbol right of the effect symbol E1 and an effect symbol middle designation command for designating the effect symbol within the effect symbol E1 as control commands. Output.

  Thereafter, when the first symbol stop command or the second symbol stop command is input from the main CPU 31a, the overall control CPU 32a displays the input first symbol stop command or the second symbol stop command as a control command. The data is output to the control CPU 33a and the sound / lamp control CPU 34a.

  When the opening designation command is input from the main CPU 31a, the overall control CPU 32a shown in FIGS. 4 and 5 outputs the input opening designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a. To do. Next, a round designation command for the first to fifteenth round effects, a round designation command for the first to seventh round effects, and a round designation for the first and second round effects from the main CPU 31a. When any of the commands is input, the overall control CPU 32a outputs the input round designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a. In addition, from the main CPU 31a, an interval designation command for the first to fifteenth interval effects, an interval designation command for the first to seventh interval effects, and an interval designation command for the first and second interval effects. Is input, the overall control CPU 32a outputs the input interval designation command to the display control CPU 33a and the sound / lamp control CPU 34a as control commands. Thereafter, when the ending designation command is inputted from the main CPU 31a, the overall control CPU 32a outputs the inputted ending designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

The overall control CPU 32a shown in FIGS. 4 and 5 uses the control commands as control signals (8-bit signals), and outputs the signals via the output port 39 and the output buffer 40 at a predetermined timing. Further, the overall control CPU 32a, in accordance with the output timing of the control signal, instructs the display control board 33 and the sound / lamp control board 34 to read a control command constituting the control signal (INT signal or , The strobe signal) is output via the output port 39 and the output buffer 40.

  As shown in FIG. 4, the display control board 33 includes the display control CPU 33a, and a display ROM (not shown) and a display RAM (not shown) are connected to the display control CPU 33a. The display RAM temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The display ROM stores a plurality of types of display effect data used when the symbol combination game is performed. The display effect data is information for the display control CPU 33a to control the display content (symbol fluctuation or the like) of the effect symbol display device 61, that is, information for instructing the effect symbol display device 61 to execute the display effect. It is.

  Further, the display ROM includes one kind of opening effect display effect data, 15 kinds of round effect display effect data, 15 kinds of interval effect display effect data used in the jackpot game after the symbol combination game, and One type of ending effect display effect data is stored. Display effect data for opening effects is stored in association with the opening effects. Each round effect display effect data is stored in association with each of the first to fifteenth round effects. Each display effect data for interval effects is stored in association with each of the first to fifteenth interval effects. Display effect data for ending effects is stored in association with the ending effects. The display effect data for the opening effect, the display effect data for the round effect, the display effect data for the interval effect, and the display effect data for the ending effect are displayed on the effect symbol display device 61 by the display control CPU 33a. This is information for instructing execution of a round effect, first to fifteenth interval effects, and an ending effect.

  Further, the display ROM stores a plurality of display effect data for effect mode used when setting the effect mode. The display effect data for effect mode is information for the display control CPU 33a to instruct the effect symbol display device 61 to set the effect mode.

  The display ROM stores a plurality of display stage display effect data (display stage data) used when an effect of displaying the display images associated with the plurality of display stages Lv0 to Lv5 is performed. Yes. The display stage display effect data is information for the display control CPU 33a to instruct the effect symbol display device 61 to execute the continuous change effect.

  When the change pattern designation command is input from the overall control CPU 32a shown in FIGS. 4 and 5, the display control CPU 33a stores the change pattern designated by the change pattern designation command in the display RAM. It has become.

  In addition, when the effect symbol left designation command is input from the overall control CPU 32a, the display control CPU 33a stores the effect symbol left designated by the command in the display RAM. Similarly, when the presentation design right designation command is input from the overall control CPU 32a, the display control CPU 33a stores the production design right designated by the command in the display RAM, and when the production design middle designation command is inputted. The effect symbols designated by the command are stored in the display RAM.

  Thereafter, when the first symbol stop command or the second symbol stop command is input from the overall control CPU 32a shown in FIGS. 4 and 5, the display control CPU 33a is stored in the display RAM that is input at the start of variation.

On the other hand, when the number of normal symbol reserved balls is larger than “0” (step S73: Y), the main CPU 31a proceeds to the process of step S74.

  In step S74, the main CPU 31a subtracts 1 from the number of normal symbol reserved balls, and proceeds to the process of step S75. In step S75, the main CPU 31a acquires the value of the random number for normal hit determination stored in the main RAM 31c in association with the number of normal symbols reserved balls, and proceeds to the process of step S76.

  In step S76, the main CPU 31a performs a normal hit determination for determining whether or not the acquired value of the random number for normal hit determination matches the normal hit determination value stored in the main ROM 31b. In the case of a normal hit in which the value of the normal hit determination random number matches the normal hit determination value (step S76: Y), the main CPU 31a proceeds to the process of step S77. In step S77, the main CPU 31a determines the final stop symbol to be fixedly stopped and displayed on the normal symbol display device 53 from the normal symbol hit symbols ("1", "2"), and proceeds to the process of step S79. Transition. More specifically, the main CPU 31a determines a winning symbol [2] advantageous to the player based on the obtained value of the normal symbol distribution random number with a probability of 6/11, and more than the winning symbol [2]. The winning symbol [1] that is disadvantageous to the player is determined with a probability of 5/11. On the other hand, in the case of a loss in which the normal hit determination random number and the normal hit determination value do not match (step S76: N), the main CPU 31a proceeds to the process of step S78. In step S78, the main CPU 31a determines the final stop symbol “0” as the normal symbol to be displayed on the normal symbol display device 53, and proceeds to the processing of step S79.

  In step S79, the main CPU 31a determines one normal symbol variation pattern from a plurality of types of normal symbol variation patterns, and proceeds to the processing of step S80. The normal symbol variation pattern is the normal symbol variation pattern for the normal state determined during the normal state where the entrance rate improvement state is not granted or the big hit game, and the entrance rate improvement state is assigned. It is classified into the determined normal pattern variation pattern for the improved entry rate state. Further, the normal symbol variation patterns for the normal state are classified into three types of patterns having different variation times. Specifically, from the first ordinary symbol variation pattern having the shortest variation time of 3000 ms, the second ordinary symbol variation pattern having a variation time of 6000 ms longer than the first ordinary symbol variation pattern, and the second ordinary symbol variation pattern. Are also classified into a third normal symbol variation pattern having a long variation time of 9000 ms. On the other hand, there is one type of normal symbol variation pattern for the entrance rate improvement state, and the variation time is the fourth normal symbol variation pattern in which a variation time (1000 ms) shorter than the first normal symbol variation pattern is set. is there.

  Then, the main CPU 31a determines the fourth normal symbol variation pattern when the entrance rate improvement state is given in step S79, and the first normal symbol change when the entrance rate improvement state is not assigned. One of the pattern, the second ordinary symbol variation pattern, and the third ordinary symbol variation pattern is determined. Note that the main CPU 31a determines the first normal symbol variation pattern with a probability of 34/101 and determines the second normal symbol variation pattern with a probability of 34/101 when the entrance rate improvement state is not given. The third normal symbol variation pattern is determined with a probability of 33/101.

  In step S80, the main CPU 31a executes various processes relating to the normal symbol variation game, and ends the process. Specifically, the main CPU 31a controls the display content of the normal symbol display device 53 so that the normal symbol starts to fluctuate. Further, the main CPU 31 a outputs a normal symbol designation command for designating a normal symbol to the overall control CPU 32 a of the overall control board 32. At the same time, the main CPU 31a starts measuring the variation time of the normal symbol variation game.

  In the present embodiment, during the symbol variation game in which the 15R probability variation big hit game is awarded, if the normal symbol variation game is won and the opening / closing blade 22b is opened, the 15R probability variation big hit game is awarded from the speakers 17a to 17c. The first certainty change notification effect for notifying is provided. Hereinafter, processing (notification processing) performed by the overall control CPU 32a of the overall control board 32 will be described. Note that a program for performing this process is repeatedly executed at every process interruption cycle (every 2 ms) in the overall control CPU 32a.

  In step S91 shown in FIG. 21, when the variation patterns P2 and P3 to which the 15R probability variable big hit game is given are input, the overall control CPU 32a notifies that the 15R probability variable big hit game is given as a big hit notice. It is determined by random lottery whether or not to execute the probability change notification effect (first probability change notification effect). In this embodiment, the probability change notification effect is executed with a probability of 1/11. If it is determined not to execute the probability change notification effect (step S91: N), the overall control CPU 32a ends the process here without performing the processes of steps S92 to S94. On the other hand, when it is determined that the probability change notification effect is to be executed (step S91: Y), the overall control CPU 32a proceeds to the process of step S92.

  In step S92, the overall control CPU 32a determines whether or not an ordinary electric accessory release designation command is input during the symbol variation game based on the variation patterns P2 and P3. The normal electric accessory opening designation command is a control command indicating that the opening / closing blade 22b opens, and the main CPU 31a outputs an opening signal to open the opening / closing blade 22b. Is output to the overall control CPU 32a. When the normal electric accessory release designation command has not been input (step S92: N), the overall control CPU 32a ends the process here without performing the processes of steps S93 and S94. On the other hand, when the normal electric release designation command is input (step S92: Y), that is, when it is determined that the probability change notification effect is to be executed, the overall control CPU 32a proceeds to the process of step S93.

  In step S93, the overall control CPU 32a determines a notification pattern of the probability change notification effect based on the normal symbol winning symbol, and proceeds to the processing of step S94. More specifically, the overall control CPU 32a opens the open / close blade 22b three times and 1500 ms elapses after the open / close blade 22b is opened in one open when the entrance rate improvement state is given. The notification pattern corresponding to the open pattern that maintains the open state is determined. In addition, the overall control CPU 32a opens the opening / closing blade 22b once and releases it in one opening when the winning rate improvement state is not given and the winning symbol is “1”. A notification pattern corresponding to an open pattern that maintains an open state until 300 ms elapses is determined. Further, the overall control CPU 32a opens the opening / closing blade 22b once and opens it in one opening when the winning rate improvement state is not given and the winning symbol is “2”. The notification pattern corresponding to the open pattern that maintains the open state until 1000 ms elapses is determined.

  In step S94, the overall control CPU 32a specifies the determined notification pattern and outputs a probability change notification effect instruction command for instructing execution of the probability change notification effect to the sound / lamp control CPU 34a of the sound / lamp control board 34, where Terminate the process. The sound / lamp control CPU 34a outputs sound from the speakers 17a to 17c so as to execute a certain change notification effect of the effect contents corresponding to the opening pattern of the opening / closing blade 22b based on the notification pattern corresponding to the input certain change notification effect instruction command. Control the content. As a result, a sound for notifying that the 15R probability variation big hit game is given from the speakers 17a to 17c while the opening / closing blade 22b is opened is output.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 of the present embodiment, when the result of the first special symbol variation game is a big hit, the main CPU 31a performs the first big hit game (15R probability variable big hit game, 15R non-probable big hit game) or It is decided to give the second jackpot game (7R probability variable jackpot game). On the other hand, when the result of the second special symbol variation game is a big hit, the main CPU 31a decides to give the first big hit game or the third big hit game (2R probability variable big hit game, 2R non-probable big hit game). To do. For this reason, the third jackpot game in which the opening time of the winning device 23 is the shortest, that is, the prize ball is most difficult to be paid out, is awarded when the result of the first special symbol variation game is a big hit. There is no. Therefore, when the result of the first special symbol variation game is a big hit, it is possible to reliably obtain a prize ball. In addition, the third jackpot game can be awarded when the result of the second special symbol variation game is a big hit, but the second special symbol variation game is sent to the second start winning device 22 in a state where the entrance rate is improved. It is started for the first time when a game ball is detected, and the improved rate of entry can be given after the end of the big hit game in which the big winning device 23 is opened. Therefore, at the time when the third jackpot game is awarded, there is a high possibility that a prize ball is paid out in the first jackpot game or the second jackpot game given before the third jackpot game. There is a high possibility that the award ball has already been paid out. Therefore, even if the result of the second special symbol variation game is a big hit, the prize ball can be obtained almost certainly. From the above, if the result of the special symbol variation game is a big hit, a winning ball can be obtained almost certainly, so that the interest of the game can be improved and the willingness to continue the game can be given.

  (2) The second start winning device 22 has a configuration in which it is difficult for the game ball to enter because the possibility that the opening / closing blade 22b is switched to the open state is low unless the ball-entry rate improvement state is given. On the other hand, since the first start winning device 21 does not have the opening and closing blades 22b, the first starting winning device 21 is configured to make it easier to enter the game ball than the second start winning device 22. For this reason, the player normally fires a game ball aiming at the first start winning device 21 first.

  Therefore, in the present embodiment, the first start winning device 21 is arranged on the flow path of the game ball passing through the left side of the effect symbol display device 61, and the second start winning device 22 is played through the right side of the effect symbol display device 61. It is arranged on the flow path. As a result, when a player launches a game ball aiming at the first start winning device 21, the possibility that the game ball enters the second start winning device 22 on the opposite side of the effect symbol display device 61 is small. Therefore, the possibility that the first special symbol variation game is executed is higher than that of the second special symbol variation game. Thereby, the possibility that the jackpot game that is given first is the first jackpot game or the second jackpot game is high. Therefore, since a large number of prize balls can be expected in the jackpot game that is given first, it is possible to have a willingness to continue the game.

  (3) The second special symbol B2 of this embodiment is a special symbol d as a symbol that gives an improved entrance rate (variation time shortened state) until 100 special symbol variation games are executed. Has a symbol to be classified. Therefore, for example, after the special symbol variation game is executed 100 times during the ending mode, the player can expect to be given the probability variation state even if the entrance rate improvement state ends and the normal mode is entered. You can be motivated to continue playing.

  (4) In this embodiment, since the total opening time of the opening / closing blades 22b of the second starting prize-winning device 22 is extended when the state of improving the winning rate is given, the opening / closing blades 22b are opened when the entering rate is improved. When it is in the state, it becomes easier for the second start winning device 22 to win a game ball than the first start winning device 21 that does not have the opening / closing blade 22b. In addition, when the result of the second special symbol variation game is a big hit, the second special symbol B2 classified as the specific symbol a (that is, the 15R probability variable big hit game) is determined with a probability of 69/100, When the result of the first special symbol variation game is a big hit, the first special symbol B1 (that is, the 15R probability variable big hit game) classified as the specific symbol A is determined with a probability of 47/100. That is, when the result of the second special symbol variation game is a big hit with a probability variation state, it is 15 rounds than when the result of the first special symbol variation game is a big hit with a probability variation state. It is easy to get a big hit game, and it is easy to win a lot of prize balls in a short time. For this reason, when the state of improving the winning rate is given, the player launches the gaming ball aiming at the second start winning device 22. Furthermore, even if the 2R non-probability big hit game is awarded in the second special symbol variation game, the 2R non-probability big hit game looks like a 2R probable big hit game that can also be given in the second special symbol variation game. It cannot be distinguished from above. Therefore, the player can play the game while expecting the provision of the probability variation state even when the 2R non-probability big hit game is awarded. In this way, the direction in which the game ball is fired, the type of the big hit game, and the game characteristics can be changed depending on whether or not the entrance rate improvement state is given, so that the player is less tired of the game, Interest is improved.

  (5) In the present embodiment, the overall control CPU 32a has a function as “production mode setting means” instead of the main CPU 31a. For this reason, the burden on the main CPU 31a can be reduced despite the large number of types of programs. In addition, an effect mode designation command, a pseudo continuous super shortening variation pattern designation command, a continuous change effect command, and the like generated by the overall control CPU 32a are output to both the display control CPU 33a and the voice / lamp control CPU 34a. For this reason, the effect mode and continuous change effect executed by the effect symbol display device 61 can be synchronized with the effect mode and continuous change effect executed by the frame lamps 16a to 16c and the speakers 17a to 17c.

  (6) In this embodiment, the jackpot determination random number, the jackpot symbol random number, the reach determination random number, and the variation pattern distribution random number are commonly used in the first special symbol variation game and the second special symbol variation game. It is a random number. Therefore, the amount of data stored in the main RAM 31c can be reduced as compared to the case where different random numbers are used for each special symbol variation game.

  (7) The first probability change notification effect of the present embodiment is executed by sound output from the speakers 17a to 17c. For this reason, even if the player is paying attention to the symbol combination game, the first probability change notification effect is executed by the sound output, so that the player can easily notice the first probability change notification effect.

  In addition, you may change the said embodiment as follows.

  In the above embodiment, the opening times of the big winning devices 23 in the first to third jackpot games are different from each other by changing the number of executions of the round effect. However, the opening times of the big winning devices 23 in the first to third jackpot games may be different from each other by changing the opening times of the big winning devices 23 in the round production per time. For example, when the first jackpot game and the second jackpot game are each configured by 10 round effects, the opening time in the round effect per time in the first jackpot game is set to 10 seconds, In the second jackpot game, the opening time for one round effect may be set to 5 seconds.

  In the above embodiment, the first start winning device 21 is arranged on the flow path of the game ball passing through the left side of the effect symbol display device 61, and the second start winning device 22 is the game ball passing through the right side of the effect symbol display device 61. It was arranged on the flow path. However, the second start winning device 22 is disposed on the flow path of the game ball passing through the left side of the effect symbol display device 61, and the first start winning device 21 is disposed on the flow path of the game ball passing through the right side of the effect symbol display device 61. May be. Further, the first start winning device 21 and the second start winning device 22 may be arranged on the same game ball flow path.

  In the above embodiment, when the symbols classified into the specific symbols A and a are determined as the special symbols B1 and B2, the mode is changed to the probability variation mode or the probability variation suggestion mode. However, when a symbol classified into the specific symbols A and a is determined, the mode may be shifted to the probability variation mode. On the contrary, when the symbols classified into the specific symbols A and a are determined, the mode may be shifted to the probability variation suggestion mode without fail.

  In the above embodiment, there are symbols classified as specific symbols a, b, d and non-specific symbols c as the second special symbol B2, but symbols classified as specific symbols b, Or the symbol classified into the specific symbol d may not exist.

  In the above embodiment, both the first probability variation suggestion mode and the second probability variation suggestion mode are set as the probability variation suggestion mode, but only the first probability variation suggestion mode is set as the probability variation suggestion mode. Also good.

  In the above embodiment, the player starts right-handed while the jackpot game is being executed. However, the player may start right-handed when the bonus game is started.
