Description

  The present invention relates to a gaming machine such as a pachinko machine or an arrangement ball machine, and more particularly, to a bullet ball game machine that executes a reach effect in a symbol combination game and has a more appropriate appearance frequency of the reach effect. is there.

  As a pachinko machine which is a kind of gaming machine, one that starts a symbol combination game with three symbols on a display device when a pachinko ball wins a winning prize opening is well known. Generally, in this type of pachinko machine, a jackpot advantageous to the player is awarded according to the result of the symbol combination of the symbol combination game. For example, the first symbol that stops first, the second symbol that stops second, and the third symbol that stops third all stop at the same symbol, so that a big hit is given. Yes.

  The effect contents of the symbol combination game are roughly divided into normal fluctuation, loss reach fluctuation, and big hit fluctuation. Normal variation means that the first symbol and the second symbol out of the three symbols are stopped at different symbols, and the third symbol is also stopped without any special effects. It is a fluctuation that ends the game. Loss and reach fluctuation means that the first symbol and the second symbol stop at the same symbol, form a reach symbol combination, and before the third symbol is stopped, a special effect is performed. This is a variation in which the symbol combination game ends with a loss. The big hit variation is a variation in which the symbol combination game ends after the reach effect, resulting in a big hit. In general, a plurality of reach effects of losing reach fluctuation are set, and the reach rate and the reliability to the jackpot are set in advance in each reach effect. In addition, the general procedure until one losing reach production is determined is as follows. First, a big hit lottery for determining whether or not to change the big hit is performed, and if the big hit lottery is not won, then a reach lottery for determining whether or not to change the big hit is performed. When the reach lottery is won, a lottery for determining which reach effect is to be executed is performed from among a plurality of reach effects set next, and the effect contents of the symbol combination game are determined. .

  However, in the case of a method in which a single reach effect is determined based on a predetermined appearance rate, even if a game is continued for a long time or a reach effect may appear, a special reach (reliability for jackpot) (High reach) may not occur. Therefore, there is a problem that the game becomes boring. For this reason, for example, the number of times the symbol combination game is executed during the period from when the special reach appears until the next special reach (hereinafter, between special reach) is counted. Conventionally, a technique for increasing the appearance rate of special reach has been proposed (see, for example, Patent Document 1). And if this conventional technology is adopted, if the number of executions of the symbol combination game between special reach reaches a predetermined number when the losing reach change is performed, the ratio of causing the special reach to increase will be increased. Become. Therefore, it is considered that a situation in which the next special reach does not occur over a long game after the occurrence of the special reach last time can be avoided, and a decrease in the interest of the game can be prevented.

As another conventional technique, a technique has been proposed in which the winning probability of losing reach variation is changed according to the number of reserved memories (see, for example, Patent Document 2). The pachinko machine is generally provided with means for storing the number of pachinko balls won at the start winning opening as a reserved ball value. If there is a pachinko ball winning at the start winning opening during the symbol combination game, the reserved ball value is stored up to a predetermined upper limit (generally it can be stored up to four), and the reserved ball value is stored after the symbol combination game is over. Based on this, a symbol combination game is started. Therefore, if the pachinko ball is won at the start winning opening exceeding the upper limit of the reserved ball value, the winning is invalidated without being counted. Therefore, in the pachinko machine described in Patent Document 2, when the number of held balls is large, the loss-reach winning probability is set low to prevent the fluctuation time of the symbol combination game from being prolonged. Conversely, when the number of held balls is small, the lose reach winning probability is set high so that the state where no reach effect is generated is shortened so that the player does not get bored with the game.

  However, according to the technique described in Patent Document 1, it is possible to surely avoid the situation where the next special reach does not occur over a long game since the last special reach occurred, but the lottery fluctuation variation that is the premise in the first place If you don't win, there will be no special reach. Therefore, when the lottery fluctuation lottery is not won for a long time, there is a problem that the player has no expectation of jackpot and the interest of the game is lowered.

  In the technique described in Patent Document 2, the lose reach winning probability is varied based on the reserved ball value. Therefore, in a gaming machine with poor nail adjustment (easy to win a start winning opening), the number of held balls tends to increase, and overall, the probability of winning a loserrech is low. On the other hand, in gaming machines where nails are difficult to adjust (it is difficult to win a start winning opening), the number of held balls tends to decrease, and overall, the probability of winning a game is increased. In other words, because the lost reach winning probability fluctuates due to the spicy adjustment of the nail adjustment, the appearance frequency of the lost reach production with respect to the number of changes of the symbol combination game varies greatly from game machine to game machine, resulting in a sense of incongruity to the player. Has occurred.

  Furthermore, if the nail adjustment is made sweeter, the appearance frequency of the lose reach production will be lowered and the interest will be cut off, and if it is hard, the appearance frequency of the lose reach production will increase too much and the expectation for the reach production will be reduced. . Therefore, when trying to avoid this, there is a problem that the nail adjustment becomes quite difficult.

  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 while minimizing the situation where the reach effect does not appear over a long game, and the appearance of the reach effect. It is an object of the present invention to provide a gaming machine that has little variation in the frequency of gaming machines and does not give the player a sense of incongruity.

In order to solve the above-mentioned problem, in claim 1, a display means for displaying a symbol combination game using a plurality of types of symbols, and a reach effect for determining whether or not to execute a reach effect in the symbol combination game A gaming machine comprising: a reach effect execution determination unit for determining whether or not execution is possible at the start of a symbol combination game; and a display control unit for displaying on the display unit a symbol combination game based on the result of the reach effect execution determination. The counting means for counting the number of times that the reach effect execution is determined before the reach effect execution is determined after the symbol combination game determined to be possible to execute the reach effect, and the count value of the counting means is Along with increasing the reach demonstration run probability changing means for setting a high reach winning probability that is determined to reach demonstration executable, criteria predetermined A reference count storage means for storing a numerical value, the count value of the counting means and a reference count arrival determining means for determining whether or not has reached the reference count, the reach demonstration run probability changing means, One reach winning probability can be set from among the plurality of reach winning probabilities different from each other, and the reach winning probability in the symbol combining game immediately after the symbol combining game determined to be reachable can be set as the plurality of the winning winning probabilities. When the reach winning probability is set to the lowest probability, and it is determined that the count value has not reached the reference count value, the reach winning probability of the symbol combination game determined to be reachable. Set higher than that of the immediately following symbol combination game, and when it is determined that the count value has reached the reference count value, the reach winning probability is set to the immediately preceding symbol combination. The reach effect execution availability determination unit compares the reach determination random number with a reach determination value when the reach effect execution enable / disable determination is performed, and the reach determination random number is the reach reach value. It is means for determining that the reach effect can be executed when the value is less than the determination value, and when the symbol combination game immediately after the symbol combination game determined to be able to execute the reach effect is determined to be able to execute the reach effect, When the reach win probability is set to the lowest probability among the plurality of reach win probabilities, the change pattern is assigned only to the change pattern that executes the super reach with a higher player's expectation for the big hit than the normal reach One variation pattern is determined from the distribution table, and a symbol combination is displayed on the display means based on the determined variation pattern. The gist is a gaming machine characterized by running a game.

  Therefore, according to the first aspect of the present invention, the number of times it is determined that the reach effect is not executed between the symbol combination game determined to be able to execute the reach effect and the next time when it is determined that the reach effect can be executed, that is, The reach effect is more likely to appear as the number of consecutive appearances of the symbol combination game that is lost without the reach effect being executed increases. Therefore, as a result that the situation where the reach effect does not appear over a long game is suppressed as much as possible, the appearance frequency of the reach effect becomes more appropriate. Therefore, the reach effect that appears moderately enables the player to maintain a sense of expectation for the big hit, thereby improving the interest of the game.

  In addition, in the present invention, a different factor for each gaming machine, such as a reserved ball value and an operating situation, is not used as a trigger for changing the probability of the reach production execution probability changing means. Variations from one to the other are reduced. Therefore, a gaming machine that does not give the player a sense of incongruity can be obtained. Further, there is no problem that the difficulty in adjusting the nail is increased.

  Here, as the aspect of “setting the reach winning probability determined that the reach effect can be executed as the count value of the counting means increases”, there are the following aspects. For example, every time the count value increases to “1, 2, 3, 4,...”, The reach winning probability is gradually set higher such as “5%, 10%, 15%, 20%. Can be illustrated. In addition, the increase rate of the reach winning probability may be constant or not. In addition, when the count value is “1-5”, “6-10”, “11-15”, the reach winning probability is set to “5%”, “10%”, “15%”, respectively. It can be illustrated.

  As a preferable example of the “reach effect execution availability determination unit”, for example, a predetermined program (referred to as a “reach effect execution availability determination program”) that performs the reach effect execution availability determination at the start of the symbol combination game is executed. And an arithmetic processing unit that performs the processing. As a preferred example of the “counting means”, for example, a predetermined number of times that the reach effect execution is determined to be possible after the symbol combination game determined to be able to execute the reach effect is determined to be reachable next. And an arithmetic processing unit that executes the program (for convenience, referred to as a “counting program”). As a preferable example of the “reach effect execution probability changing means”, for example, a predetermined program (for the sake of convenience, “reach effect for convenience”) that sets a reach winning probability that is determined to be possible to execute reach effect as the count value of the counting means increases. An arithmetic processing device that executes a “execution execution probability change program”.

  In this case, the functions as the reach effect execution possibility determination unit, the counting unit, and the reach effect execution probability change unit may be realized by using different arithmetic processing devices, or may be realized by using one common arithmetic processing device. May be. In the latter case, it is possible to reduce the number of arithmetic processing units and prevent an increase in the number of parts, and it is easy to execute a series of processes quickly and reliably.

  In addition, in the case of a gaming machine that includes a main control unit that determines the outline of the content of the game effect, and includes a plurality of sub-control units that determine more specific effect content based on the variation pattern determined by the main control unit, It is preferable that the functions as the reach effect execution possibility determination unit, the counting unit, and the reach effect execution probability change unit are realized using a CPU (central processing unit) included in the main control unit. That is, since it is basically only necessary to add a reach effect execution feasibility determination program, a counting program, and a reach effect execution probability change program, an existing CPU in the main control means is sufficient without adding a new CPU. It is. In this case, the various programs are preferably stored in, for example, a ROM (read only storage device) included in the main control unit.

  The gaming machine preferably further includes count value clearing means for clearing the count value of the counting means to zero when the reach effect execution availability determination means determines that the reach effect execution is possible. . This is because if the count value is left as it is, the counting means may hinder the next counting.

Further, according to the invention described in claim 1, and the reference count value reference count storage means stores, by comparing the count value of the counting means, the number of times it is determined that not reach demonstration run It is determined whether the value has reached a predetermined value. That is, when the number of consecutive appearances of a symbol combination game that has been lost without execution of the reach effect reaches a predetermined number, the reach effect is more likely to appear than in the immediately preceding symbol combination game.

  Here, the reference count value is not limited to one, and may be two or more. That is, the reference count value storage means stores a plurality of predetermined reference count values, and the reference count value arrival determination means determines whether the count value of the counting means has reached the reference count value. The determination may be performed for each of a plurality of reference count values.

  As a preferred example of the “reference count value arrival determination means”, for example, a predetermined value for determining whether or not the count value of the count means has reached the reference count value by comparing the count value of the count means with the reference count value is used. And an arithmetic processing unit that executes the program (referred to as a “reference count value arrival determination program” for convenience).

  In addition, in the case of a gaming machine that includes a main control unit that determines the outline of the content of the game effect, and includes a plurality of sub-control units that determine more specific effect content based on the variation pattern determined by the main control unit, It is preferable to realize the function as the reference count value arrival determination means by using a CPU included in the main control means. That is, basically only the addition of the reference count value arrival determination program is required, so that an existing CPU in the main control means is sufficient without adding a new CPU. In this case, the program is preferably stored in, for example, a ROM included in the main control means. In addition, it is preferable that the ROM included in the main control unit serves as a reference count value storage unit.

Further , according to the first aspect of the present invention, in the symbol combination game immediately after the reach effect, since the reach winning probability with the lowest probability is set, the appearance frequency of the reach effect is the lowest. . For this reason, it is possible to suppress as much as possible that the reach effect that results in the loss appears continuously (or frequently appears in a short time). As a result, it is possible to suppress giving a sense of expectation to the player as much as possible.

  For example, it is assumed that the reach winning probability is set to three levels of “1/241” (low probability), “18/241” (medium probability), and “53/241” (high probability). In this case, when the reach winning probability is set to “18/241” (medium probability) and it is determined that the reach effect can be executed, the reach winning probability in the symbol combination game immediately after the symbol combination game is determined. Is changed to “1/241” (low probability). In addition, when it is determined that the reach effect can be executed in a state where the reach winning probability is set to “53/241” (high probability), the reach winning probability is determined in the symbol combination game immediately after the symbol combination game. The setting is changed to the lowest “1/241” (low probability). As described above, the symbol combination game immediately after the symbol combination game determined to be able to execute the reach effect is “1/241” (low probability), and as a result, the appearance frequency of the reach effect is the lowest.

The reach production execution probability changing means may be capable of setting the reach winning probability to “three levels of low, medium and high” as described above, for example, “low, medium, high and extreme” It may be settable to “high four steps” or “five steps of extremely low, low, medium, high and extremely high”.
According to a second aspect of the present invention, in the first aspect, when it is determined that the symbol combination game immediately after the symbol combination game determined to be able to execute the reach effect is determined to be able to execute the reach effect, the reach winning probability is plural. When the reach probability is not set to the lowest probability, one variation pattern distribution table in which both the variation pattern for executing the normal reach and the variation pattern for executing the super reach are allocated is selected. The gist is to determine the fluctuation pattern.
According to a third aspect of the present invention, in the first or second aspect, the reference count value storage means stores a plurality of the reference count values, and the reference count value arrival determination means determines that the count value is the reference count value. The gist of this is to determine whether or not it has been reached for each of a plurality of reference count values.
According to a fourth aspect of the present invention, in any one of the first to third aspects, the reach effect execution probability changing means calculates the reach winning probability in the symbol combination game immediately after the symbol combination game determined to be a big hit. The gist is to set the lowest probability among the plurality of reach winning probabilities.

The reach determination random number includes a reach random number update unit that updates the reach determination random number at predetermined time intervals and a reach random number acquisition unit that acquires the reach determination random number. The reach determination random number and the reach determination value are compared when performing the feasibility determination, and the reach determination random number acquired by the reach random number acquisition unit is greater than or equal to a predetermined reference value within the range and less than or equal to the reach determination value The reach effect execution probability changing means increases the reach determination value within the range as the count value of the counting means increases. Preferably it is a means.

In this case, when the reach determination random number is a value exceeding the reach determination value, it is determined that the reach effect is not executed, and the reach effect is not executed in the symbol combination game in this case. On the other hand, when the reach determination random number is not less than the reference value and not more than the reach determination value, it is determined that the reach effect can be executed. In this case, the reach effect is executed. In the present invention, since a simple process for determining whether or not the acquired reach random number is not less than the reference value and not more than the reach determination value is performed, the processing load can be greatly reduced. In addition, when it is desired to increase the probability of executing the reach effect, it is only necessary to change the reach determination value to a large value, so that it is not difficult to secure a storage area and the development burden can be reduced. .

  On the other hand, for example, a method of using a plurality of reach determination values and sequentially comparing all of the plurality of reach determination values with the acquired reach determination random number is also conceivable. To give a specific example, for example, there are 241 numerical values “0 to 240” within a predetermined range, and the numerical value of the reach determination random number is added one by one at a fixed time in this range (240 When 1 is added in this state, it is returned to 0.) If the reach determination value is composed of 20 random numbers such as “0”, “5”, “51”, “67”, “103”..., The obtained reach determination random number and the 20 It is necessary to perform a process of sequentially comparing numerical values, and the processing load is very large. In addition, in order to increase the probability of executing the reach effect, in addition to the above 20 reach determination values, a plurality of “3”, “17”, “23”, “111”. Therefore, it becomes difficult to secure an area for storing a new reach determination value, resulting in an increase in development burden.

  As a preferred example of the “reach random number update means”, an arithmetic processing unit that executes a predetermined program (for convenience, referred to as “reach random number update program”) that updates the reach determination random number within a predetermined range at regular intervals. Can be mentioned. A preferable example of the “reach random number acquisition means” includes an arithmetic processing unit that executes a predetermined program for acquiring reach determination random numbers (for convenience, referred to as “reach determination random number acquisition program”). These programs are usually executed by the CPU of the main control means. Note that these programs and reach determination values are preferably stored in, for example, a ROM included in the main control means. The reach determination random number is preferably temporarily stored in, for example, a RAM (rewritable storage device) included in the main control unit.

  A reach mode setting means for setting one of a plurality of reach modes corresponding to the reach winning probability may be provided. In this case, the reach production execution probability changing means changes the reach mode set by the reach mode setting means to a higher probability reach mode as the count value of the counting means increases, and the high probability It is preferable that the reach determination value is increased within the range in accordance with the change to the reach mode.

  According to this configuration, when the number of consecutive appearances of the symbol combination game that is lost without executing the reach effect is increased, the preset reach mode is changed to a reach mode with a higher probability, and accordingly the reach mode is changed. The judgment value is increased within the range. As a result, the probability that it is determined that the reach determination random number is not less than the reference value and not more than the reach determination value is increased, and the reach effect is easily performed.

  Here, as a preferable example of the “reach mode setting means”, any one of a plurality of reach modes corresponding to the reach winning probability is set, and the set reach mode is temporarily stored in a specific storage area. And an arithmetic processing unit that executes a predetermined program (referred to as a “reach mode setting program” for convenience). In this case, it is preferable that the function as the reach mode setting means is realized by using the CPU of the main control means. In addition, the reach mode set by the reach mode setting unit is preferably temporarily stored in, for example, a RAM included in the main control unit. The “reach mode setting” refers to, for example, temporarily setting a flag corresponding to each reach mode, and specifically “0”, “1”, “2”, etc. in a specific storage area. This means temporarily storing a numerical value indicating the flag.

As described in detail above, according to the first to fourth aspects of the present invention, it is possible to improve the interest of the game while suppressing the situation where the reach effect does not appear over a long time game as much as possible. It is possible to provide a gaming machine that has little variation in appearance frequency among gaming machines and does not give a player a sense of incongruity. In particular, according to the first aspect of the present invention, it is possible to suppress a reach effect that results in a loss from appearing continuously several times (or frequently appearing in a short time) as much as possible. Giving a sense of hopelessness as much as possible is suppressed as much as possible, thereby making it possible to improve the fun of the game with certainty.

  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 FIGS.

  As schematically shown in FIG. 1, on the front side of the front frame 12 constituting the pachinko machine 10, there is a glass holding provided with a glass frame for protecting the game board 13 arranged inside the machine in a transparent state. The frame 14 and the upper ball tray 15 are assembled so as to be openable and closable in a laterally open state. A frame lamp 16 a is provided on the front side of the glass holding frame 14, and a board surface lamp 16 b is provided in the game area 13 a of the game board 13. The frame lamp 16a and the board surface lamp 16b are adapted to perform effects by lighting decoration such as lighting (flashing) and extinguishing according to various game performance states (big hit, reach, etc.). In addition, on both sides of the upper ball tray 15, speakers 17 are provided for outputting various sounds (sound effects, language sounds, etc.) according to the game performance state. A lower ball tray 16 and operation means 20 are mounted on the lower part of the front frame 12.

  As shown in FIG. 1, a frame-shaped center accessory 21 having a rectangular opening is disposed at a substantially central portion of the game area 13 a of the game board 13. A symbol display device 18 (display means) for displaying a symbol combination game using a plurality of types of symbols is disposed on the back side of the center accessory 21. In the symbol display device 18, a game effect (display effect) based on a varying image (or image display) is performed. In the symbol display device 18, a symbol combination game is performed in which a plurality of types of symbols are varied in a plurality of columns and a symbol combination is derived in relation to the display effect.

  Below the symbol display device 18, there is provided a start winning opening 19 that serves as a condition for starting symbol variation displayed on the symbol display device 18 when a game ball enters. The start winning opening 19 is opened and closed by a solenoid (not shown). Below the start winning opening 19 is a large winning opening 24 that is opened and closed by a solenoid (not shown). Further, a winning detection switch SW1 (see FIG. 2) for detecting a passed game ball is provided in the back of the start winning opening 19. The winning detection switch SW1 is in an ON state while detecting a passing game ball, and outputs a detection signal. On the other hand, the winning detection switch SW1 is turned off when the game ball is not passing and does not output a detection signal.

  As shown in FIG. 2, the pachinko machine 10 includes a main control board 31, an audio control board 32, a lamp control board 34, and a display control board 33. An audio control board 32, a lamp control board 34, and a display control board 33 are connected to the main control board 31, respectively. Control signals output from the main control board 31 are input to the sound control board 32, the lamp control board 34, and the display control board 33.

  The main control board 31 includes a main CPU 31a, and a ROM 31b and a RAM 31c are connected to the main CPU 31a. The main CPU 31a uses various random numbers such as a jackpot random number, a jackpot symbol random number, a lost symbol random number, a loose middle symbol random number, a lost right symbol random number, and a random number for variable pattern distribution used in various lotteries relating to the symbol combination game. Is updated every predetermined period. Further, the main CPU 31a updates the reach determination random number every predetermined time within a predetermined range. In the present embodiment, the numerical value of the reach determination random number within a predetermined range is 241 numerical values of “0 to 240” (see FIG. 3A). That is, the main CPU 31a has a function as “reach random number updating means”. Then, the main CPU 31a rewrites the value before update by setting the updated value in the setting area of the RAM 31c. The RAM 31c stores various information that can be appropriately rewritten during the operation of the pachinko machine 10. The ROM 31b stores a control program (main processing program, timer interrupt processing program, power-off processing program, etc.) for controlling the pachinko machine 10, and a plurality of types of variation patterns. The variation pattern is a game from the time when symbols in each column displayed on the symbol display device 18 start changing (beginning of the symbol combination game) to the time when symbols in all the columns are stopped (the symbol combination game ends). This shows a pattern serving as a base for the effects (display effects, light emission effects, and sound effects).

  The variation pattern is associated with the time and content of the game effect for each variation pattern, and at least the time of the game effect can be specified. The variation patterns for the symbol combination game are classified into a loss effect, a lose reach effect, and a jackpot effect, and a plurality of types of variation patterns are assigned to each category. The lose effect is an effect that the symbol combination game is developed so as to stop at the combination of loses without going through the reach effect. The lost reach effect is an effect that the symbol combination game is developed so as to stop at the lost combination after reaching the reach effect. The jackpot effect is an effect in which the symbol combination game is developed so as to stop at the jackpot combination after reaching the reach effect. The reach effect (normal reach, super reach, premier reach, etc.) is an effect that is performed after the reach is formed until it is stopped or temporarily stopped by a combination of big hits or combinations of losers.

  The ROM 31b shown in FIG. 2 stores variation pattern distribution tables T1 to T4 (see FIGS. 4A to 4D) in which variation patterns for symbol combination games are distributed. In the variation pattern distribution tables T1 and T2, variation patterns for loss reach production are distributed. The variation pattern distribution table T3 distributes the variation pattern for the loss effect, and the variation pattern distribution table T4 distributes the variation pattern for the big hit effect. It should be noted that the variation pattern for the lost reach effect and the jackpot effect includes a pattern for normal reach, a pattern for super reach, and a pattern for premier reach. Each variation pattern is associated with a variation pattern distribution random number value (for example, 100 integers from 0 to 99).

  Next, various processes related to the symbol combination game executed by the main CPU 31a (such as jackpot determination, reach effect execution determination, stop symbol determination, variation pattern determination, etc.) will be described.

  The main CPU 31a shown in FIG. 2 receives the jackpot that is updated at predetermined intervals when an on-state detection signal is input from the winning detection switch SW1, that is, when a winning of a game ball is detected. The random number value and the jackpot symbol random number value are read from the RAM 31c, and the values are stored (stored) in a predetermined storage area of the RAM 31c. The main CPU 31a compares the jackpot random number stored in the RAM 31c with the jackpot determination value stored in the ROM 31b at the start of the symbol combination game (immediately before starting), and determines whether or not the jackpot is a big hit. Judgment (win lottery) is performed. When the determination result of the big hit determination is affirmative (the value of the big hit random number matches the big hit determination value), the main CPU 31a determines the big hit. In the present embodiment, values that can be taken by the jackpot random number are set to 0 to 314 (total of 315 types of integers) (see FIG. 3B). Then, the main CPU 31a uses a single jackpot determination value (“7” in the present embodiment) determined in advance from among the values that can be taken by the jackpot random number, and determines the jackpot determination by setting the jackpot lottery probability to 1/315. Do.

  When the big hit is determined, the main CPU 31a shown in FIG. 2 causes the symbols to be finally stopped by the symbol display device 18 (stop symbol left, middle, right) so that all the columns are of the same type. To decide. Specifically, the stop symbol left, the stop symbol in the middle, and the stop symbol right (each stop symbol is the same type) are determined based on the value of the jackpot symbol. The determined stop symbol left, stop symbol, and stop symbol right are finally derived to the symbol display device 18 as a left symbol, a middle symbol, and a right symbol. In the present embodiment, the numbers that can be taken by the random numbers for the jackpot symbol are eight integers from 0 to 7, and one numerical value is associated with each symbol type (for example, the symbol “1” is a jackpot symbol) The random number value “0” is associated). Then, the main CPU 31a stores the data corresponding to the determined stop symbol left, stop symbol, and stop symbol right in the RAM 31c until the process related to the next symbol combination game is performed. Further, the main CPU 31a reads the value of the random number for variation pattern distribution from the RAM 31c, and determines one variation pattern from the variation patterns for the jackpot effect by referring to the variation pattern distribution table T4 based on the value. To do.

  When the determination result of the big hit determination is negative (the value of the big hit random number does not match the big hit determination value), the main CPU 31a shown in FIG. 2 acquires the reach determination random number from the RAM 31c. That is, the main CPU 31a has a function as a reach random number acquisition unit. Then, the main CPU 31a compares the acquired reach determination random number value with the reach determination value stored in the ROM 31b. Specifically, the main CPU 31a has a reach determination random number that is equal to or greater than a predetermined reference value (“0” in the present embodiment) within a range of “0 to 240” and equal to or less than the reach determination value. It is determined whether or not. In other words, the main CPU 31a determines whether or not the value of “reach determination random number” − “reach determination value” is smaller than zero. As a result, a reach effect execution feasibility determination is performed as to whether or not to execute a lose reach. That is, the main CPU 31a has a function as “reach effect execution availability determination means”.

  When the determination result of the reach effect execution determination is affirmative (when it is determined that reach effect execution is possible), that is, when the value of “reach determination random number” − “reach determination value” is smaller than 0, it is shown in FIG. The main CPU 31a determines a lose reach. Then, the main CPU 31a performs the number of times (count value) determined that the reach effect execution is rejected from the symbol combination game determined to be able to execute the reach effect, that is, the lose effect after the lose reach effect is executed. Clear the number of times to zero. That is, the main CPU 31a has a function as “count value clearing means”. Further, the main CPU 31a determines the stop 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 stop symbol left and the stop symbol right (both stop symbols are the same type) are determined based on the value of the lost symbol for the left symbol, and the stop symbol is determined based on the value of the random symbol for the lose symbol. decide. If the value of the lost symbol random number and the value of the lost symbol random number match, the main CPU 31a determines the stop symbol so that the stop symbol left and the stopped symbol do not match. In this embodiment, in the same way as the value of the jackpot symbol random number, the random numbers of the left symbol for the lost symbol, the random symbol for the middle symbol for the lost symbol, and the random number for the right symbol for the lost symbol are 8 integers ranging from 0 to 7. And one numerical value is associated with each symbol type. Further, the main CPU 31a reads the random value for variation pattern distribution from the RAM 31c, and refers to the variation pattern distribution table T1 or the variation pattern distribution table T2 based on the value, from among the variation patterns for the lost reach production. One variation pattern is determined.

  Then, the main CPU 31a shown in FIG. 2 sets one of three reach modes (low probability, medium probability, high probability) corresponding to the probability (reach winning probability) that is determined to be reachable execution. . That is, the main CPU 31a has a function as “reach mode setting means”.

  When a reach mode with a low probability (hereinafter referred to as “low probability”) is set, the reach determination value is set to “1”. For this reason, as shown in FIG. 3A, the probability that the value of “reach determination random number” − “reach determination value” is smaller than 0 is “1/241”, and the reach winning probability is low. (See points A1 and A2 in FIG. 5). That is, it is determined that the reach effect can be executed only when the reach determination random number is “0”. In addition, when the reach mode of medium probability (hereinafter referred to as “medium probability”) is set, the reach determination value is set to “18”. For this reason, the probability that the value of “reach determination random number” − “reach determination value” is less than 0 is “18/241”, and the reach winning probability is a medium probability (see point B in FIG. 5). That is, it is determined that the reach effect can be executed only when the reach determination random number is “0 to 17”. When the reach mode with high probability (hereinafter referred to as “high probability”) is set, the reach determination value is set to “53”. Therefore, the probability that the value of “reach determination random number” − “reach determination value” is smaller than 0 is “53/241”, and the reach win probability is high (see point C in FIG. 5). That is, it is determined that the reach effect can be executed only when the reach determination random number is any one of “0 to 52”. As described above, the reach win probability is different for each reach mode.

  On the other hand, when the determination result of the reach effect execution determination is negative (when it is determined that the reach effect execution is not possible), that is, when the value of “reach determination random number” − “reach determination value” is greater than 0, the main CPU 31a , Determine the loss (the loss without reach). Then, the main CPU 31a determines stop symbols left, middle, and right so that all columns do not become the same type of symbols. Specifically, the stop symbol left is determined based on the value of the lost symbol for the left design, the stop symbol is determined based on the value of the random symbol for the lost symbol, and the stop is determined based on the value of the random number for the lose right symbol. Determine the symbol right. If the value of the lost symbol random number and the value of the lost right symbol random match, the main CPU 31a determines the stop symbol right so that the stop symbol left does not match the stop symbol right. Further, the main CPU 31a reads a random value for variation pattern distribution from the RAM 31c, and refers to the variation pattern distribution table T3 based on the value to determine the variation pattern for the loss effect.

  Further, the main CPU 31a shown in FIG. 2 measures the count value. This measurement is performed until the main CPU 31a determines that the reach effect can be executed next. That is, the main CPU 31a has a function as “counting means”. Further, the main CPU 31a shown in FIG. 2 determines whether or not the count value has reached a predetermined reference count value. That is, the main CPU 31a has a function as “reference count value arrival determination means”. The reference count value (“16” in this embodiment) is stored in the ROM 31b. That is, the ROM 31b has a function as “reference count value storage means”.

  When it is determined that the count value has not reached the reference measurement value, the main CPU 31a sets the “medium” reach mode among the plurality of reach modes. On the other hand, when it is determined that the count value has reached the reference count value, the main CPU 31a sets the “high accuracy” reach mode among the plurality of reach modes. In these cases, the main CPU 31a sets the reach winning probability higher than that in the previous symbol combination game. That is, the main CPU 31a sets the probability that the reach effect is executed stepwise as the number of appearances of the symbol combination game that is lost without the reach effect being executed increases. In other words, as the count value increases, the main CPU 31a changes the reach mode set by the main CPU 31a to a reach mode with a higher probability, and sets the reach win probability in a stepwise manner. That is, the main CPU 31a has a function as “reach effect execution probability changing means”. In the present embodiment, the main CPU 31a sets the reach determination value within the range of reach determination random numbers (“0 to 240”) as the count value increases, from “1” → “18” → “ 53 "is increased step by step. In addition, the main CPU 31a sets the reach mode to the lowest “low probability” in the symbol combination game immediately after the symbol combination game determined to be able to execute the reach effect. Therefore, when it is determined that the reach effect can be executed in a state where the reach mode is set to “medium probability” or “high accuracy”, the reach mode is set to “low” in the symbol combination game immediately after the symbol combination game. The setting is changed to “OK”.

  Thereafter, the main CPU 31a, which has determined the stop symbol and the variation pattern, sends a predetermined control command to the sub CPU 32a of the sound control board 32, the sub CPU 34a of the lamp control board 34, and the sub CPU 33a of the display control board 33 at a predetermined timing. To output. Specifically, the main CPU 31a first generates and outputs a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation. Next, the main CPU 31a outputs a left symbol designating command for designating the stop symbol left, a right symbol designating command for designating the stop symbol right, and a middle symbol designating command for designating the stop symbol.

  Further, the main CPU 31a shown in FIG. 2 confirms a symbol variation time predetermined for each variation pattern, and sets (temporarily stores) a variation timer in the main CPU 31a at the symbol variation time. When the symbol display on the symbol display device 18 is started, the main CPU 31a starts subtraction of the symbol variation time stored in the variation timer. At this time, the symbol variation time is subtracted every predetermined interrupt period (4 ms). When it is determined that the symbol variation time is 0 ms, the main CPU 31a ends the subtraction of the variation timer and outputs a confirmation command instructing the stop of symbols in each column.

  As shown in FIG. 2, the display control board 33 includes a sub CPU 33a, and a ROM 33b and a RAM 33c are connected to the sub CPU 33a. The RAM 33c temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10. Various image information (design image information, background image, character image, appearance character image, reach effect, etc.) is stored in the ROM 33b.

  The ROM 33b stores a plurality of types of effect data for display effects that are used when a normal game effect is performed. Each effect data is stored in association with each variation pattern. The effect data is for the sub CPU 33a to instruct the execution of the effect with the time and content based on the information for controlling the display content (symbol variation, character movement, etc.) of the symbol display device 18, that is, the variation pattern. Information.

  The variation pattern designation command is inputted from the main CPU 31a to the sub CPU 33a shown in FIG. Further, the left symbol designating command, the right symbol designating command, and the middle symbol designating command are inputted to the sub CPU 33a from the main CPU 31a.

  When the change pattern designation command is input, the sub CPU 33a selects one effect data designated by the change pattern designation command from the plurality of types of effect data stored in the ROM 33b. Yes. The sub CPU 33a stores the selected effect data in the storage area of the RAM 33c. Further, the sub CPU 33a selects a symbol to be stopped in the symbol combination game based on the left symbol designation command, the right symbol designation command and the middle symbol designation command. For example, when a left symbol designation command for designating a symbol “1” is input, “1” is displayed as the left symbol. That is, the sub CPU 33a has a function as display control means for causing the symbol display device 18 to display a symbol combination game based on the determination result of whether or not the reach effect can be executed.

  As a result of the above, since one symbol display device 18 can enjoy symbol combinations of different types of effects, a fresh taste is produced in the variable display of symbols, and the player's interest can be attracted.

  Thereafter, when the confirmation command is input from the main CPU 31a shown in FIG. 2, the sub CPU 33a, based on the left symbol designation command, the right symbol designation command and the middle symbol designation command inputted at the start of the variation, 18 is instructed to stop all symbols. As a result, the designated symbol is stopped and displayed on the symbol display device 18. At this time, when all the symbols are stopped and the display result is a big hit, a chance to acquire a large number of game balls (prize balls) is given by opening the big winning opening 24 (see FIG. 1).

  As shown in FIG. 2, the voice control board 32 includes a sub CPU 32a, and a ROM 32b and a RAM 32c are connected to the sub CPU 32a. The RAM 32c temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10. Various control programs and the like are stored in the ROM 32b.

  Further, the sub CPU 32a is configured to set production data for audio production used when production is performed. Production data for audio production is associated with each variation pattern. The production data for audio production is information for the sub CPU 32a to control the audio output mode (the type of sound effect, the type of language audio, the audio output time, etc.) of the speaker 17.

  Then, when the variation pattern designation command is input from the main CPU 31a, the sub CPU 32a shown in FIG. 2 receives one piece of effect data designated by the variation pattern designation command from among a plurality of types of effect data for sound effects. The selected effect data is selected and stored in the storage area of the RAM 32c. As a result, the sub CPU 32a performs voice control based on voice production effect data corresponding to the variation pattern designation command. More specifically, the sub CPU 32a converts sound effect data stored in the RAM 32c into sound signals and outputs the sound signals to the speaker 17. As a result, the speaker 17 can perform a predetermined notification operation (sound output) based on the sound signal. Thereafter, when the confirmation command is input from the main CPU 31a, the sub CPU 32a instructs to stop the sound output of the speaker 17.

  The lamp control board 34 includes a sub CPU 34a, and a ROM 34b and a RAM 34c are connected to the sub CPU 34a. The RAM 34c temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10. Various control programs and the like are stored in the ROM 34b.

  Further, the sub CPU 34a shown in FIG. 2 sets the effect data for the light emission effect used when the effect is performed. Production data for light emission production is associated with each variation pattern. The effect data for the light emission effect is information for the sub CPU 34a to control the light emission output mode of the frame lamp 16a and the panel lamp 16b.

  When the change pattern designation command is input, the sub CPU 34a selects one piece of effect data designated by the change pattern designation command from the plurality of types of effect data for the light emission effect, and selects the selected effect data. The data is stored in the storage area of the RAM 34c. Thereby, the sub CPU 34a performs light emission control based on the production data for the light emission effect corresponding to the variation pattern designation command. More specifically, the sub CPU 34a converts the production data for the light emission effect stored in the RAM 34c into a light emission control signal and outputs it to the frame lamp 16a and the panel lamp 16b. As a result, the frame lamp 16a and the panel lamp 16b can perform a predetermined notification operation (lighting, blinking, etc.) based on the light emission control signal. Thereafter, when the confirmation command is input from the main CPU 31a, the sub CPU 34a instructs to turn off the frame lamp 16a and the panel lamp 16b.

  Next, processing (timer interrupt processing) performed by the main CPU 31a of the main control board 31 will be described. Note that a program for performing this process is executed in the main CPU 31a every predetermined interrupt period (every 4 ms).

  In FIG. 6, the main CPU 31a proceeds to the process (input process) of step S100 and executes a subroutine shown in FIG.

  The subroutine shown in FIG. 7 includes the processes of steps S200 to S204. In step S200, the main CPU 31a determines whether or not the game ball has won by the winning detection switch SW1 provided in the start winning opening 19. When the game ball wins (step S200: Y), the main CPU 31a proceeds to the process of step S201. On the other hand, when the game ball has not won (step S200: N), the main CPU 31a ends the present subroutine without performing the processes of steps S201 to S204.

  In step S201, the main CPU 31a determines whether or not the number of reserved balls of the game ball that is added in step S202 described later and subtracted in step S301 described later is less than “4” at the present time. When the number of reserved balls is less than 4 (step S201: Y), the main CPU 31a proceeds to the process of step S202. On the other hand, when the number of reserved balls is 4 or more (step S201: N), the main CPU 31a ends this subroutine without adding the number of reserved balls any more and without performing the processing of steps S202 to S204. That is, in the pachinko machine 10 of the present embodiment, the upper limit of the number of reserved balls is set to four.

  In step S202, the winning of the game ball is determined in step S200, and since it is determined in step S201 that the number of held balls is less than 4, the main CPU 31a adds 1 to the number of held balls, The process proceeds to step S203. In step S203, the main CPU 31a acquires a big hit random number that is updated as needed in a random number update process described later, and proceeds to the process of step S204. The jackpot random number acquired here is used when performing the process of step S302 described later. In step S204, the main CPU 31a stores the jackpot random number acquired in step S203 in the RAM 31c. At this time, the main CPU 31a stores each jackpot random number so that it can be understood which jackpot random number has been acquired for each number of reserved balls. Then, the main CPU 31a ends this subroutine.

  When the subroutine shown in FIG. 7 is completed, the main CPU 31a proceeds to the process of step S101 (random number update process) shown in FIG. 6, and executes the subroutine shown in FIG.

  The subroutine of FIG. 8 includes the processes of steps S800 to S808. In step S800, the main CPU 31a determines whether or not the big hit random number added by 1 in step S801 described later is 314. When the big hit random number is not 314 (step S800: N), the main CPU 31a proceeds to the process of step S801. On the other hand, if the big hit random number is 314 (step S800: Y), the main CPU 31a proceeds to the process of step S802.

  In step S801, the main CPU 31a increments the jackpot random number by 1, and proceeds to the process of step S803. In step S802, since it is determined in step S800 that the big hit random number is 314, the main CPU 31a clears the big hit random number (sets it to 0), and proceeds to the processing in step S803. In other words, in steps S800 to S802, the main CPU 31a performs a process of adding one big hit random number one by one and returning it to 0 when 314 is added. Therefore, the big hit random number is updated one by one within the range of 0 to 314.

  In step S803, the main CPU 31a determines whether or not the reach determination random number added by 1 in step S804 described later is 240. If the reach determination random number is not 240 (step S803: N), the main CPU 31a proceeds to the process of step S804. On the other hand, when the reach determination random number is 240 (step S803: Y), the main CPU 31a proceeds to the process of step S805.

  In step S804, the main CPU 31a adds 1 to the reach determination random number, and proceeds to the process of step S806. In step S805, since the reach determination random number is determined to be 240 in step S803, the main CPU 31a clears the reach determination random number (sets it to 0), and proceeds to step S806. That is, in steps S803 to S805, the main CPU 31a performs a process of adding reach determination random numbers one by one and returning to 0 when 240 is added. Therefore, the reach determination random number is updated one by one within the range of 0 to 240.

  In step S806, the main CPU 31a determines whether or not the variation pattern distribution random number added by 1 in step S807 described later is 99. When the random number for distribution pattern distribution is not 99 (step S806: N), the main CPU 31a proceeds to the process of step S807. On the other hand, if the variation pattern distribution random number is 99 (step S806: Y), the main CPU 31a proceeds to the process of step S808.

  In step S807, the main CPU 31a increments the variation pattern distribution random number by 1, and ends the present subroutine. In step S808, the main CPU 31a determines that the variation pattern distribution random number is 99 in step S806. Therefore, the main CPU 31a clears the variation pattern distribution random number (sets it to 0) and ends this subroutine. . That is, in step S806 to step S808, the main CPU 31a performs a process of adding the variation pattern distribution random numbers one by one and returning to 0 when 99 is added. For this reason, the random numbers for distributing the variation pattern are updated one by one within the range of 0 to 99.

  When the subroutine shown in FIG. 8 ends, the main CPU 31a proceeds to the process of step S102 shown in FIG. In step S102, the main CPU 31a determines whether or not a symbol combination game is being performed on the symbol display device 18. When the symbol combination game is being performed (step S102: Y), the main CPU 31a proceeds to the process of step S104 without performing the process of step S103. On the other hand, when the symbol combination game is not being performed (step S102: N), the main CPU 31a proceeds to the process of step S103 (symbol combination game start processing) and executes the subroutine shown in FIG.

  The subroutine of FIG. 9 includes the processes of steps S300 to S304. In step S300, the main CPU 31a determines whether or not the number of reserved balls of game balls is “0” at the present time. When the number of reserved balls is other than 0 (1 to 4) (step S300: N), the main CPU 31a proceeds to the process of step S301 to start the symbol combination game. On the other hand, when the number of reserved balls is 0 (step S300: Y), the main CPU 31a ends this subroutine without performing the processing of steps S301 to S304 without further subtracting the number of held balls.

  In step S301, the main CPU 31a subtracts 1 from the number of reserved balls, and proceeds to the process of step S302. In step S302, the main CPU 31a performs a jackpot determination that compares the jackpot random number stored in the RAM 31c in the step S204 with the jackpot determination value. Here, the big hit determination value is set to “7”. If the comparison result is the same (step S302: Y), the main CPU 31a shifts to the process of step S304 (big hit setting process) to execute the subroutine shown in FIG. . On the other hand, if the comparison results do not match (step S302: N), the main CPU 31a shifts to the processing of step S303 (losing setting processing) in order to make the symbol combination game to be performed a loss, and executes the subroutine shown in FIG. Execute.

  The subroutine of FIG. 10 includes the processes of steps S400 to S414. The main CPU 31a proceeds to the process of step S400 (reach determination probability setting process) and executes the subroutine shown in FIG.

  The subroutine of FIG. 11 includes the processes of steps S500 to S504. In step S500, the main CPU 31a determines whether or not the reach mode set in steps S406, S411, and S412 to be described later is “low probability”. That is, the main CPU 31a determines whether or not the reach mode flag is “0”. When the reach mode is “low probability” (step S500: Y), the main CPU 31a proceeds to the process of step S501. On the other hand, when the reach mode is not “low probability” (step S500: N), the main CPU 31a proceeds to the process of step S502.

  In step S501, the main CPU 31a sets the reach determination value to “1” because the reach mode is determined as “low probability” in step S500, and ends the present subroutine. As a result, the probability of affirmation in the determination of whether or not reach performance can be performed is reduced.

  In step S502, the main CPU 31a determines whether or not the reach mode is “intermediate”. That is, the main CPU 31a determines whether or not the reach mode flag is “1”. When the reach mode is “intermediate” (step S502: Y), the main CPU 31a proceeds to the process of step S503. On the other hand, when the reach mode is not “intermediate” (step S502: N), the main CPU 31a proceeds to the process of step S504.

  In step S503, the main CPU 31a determines that the reach mode is “intermediate” in step S502, and therefore sets the reach determination value to “18” and ends the present subroutine. Thereby, the probability of being affirmative in the determination of whether or not the reach effect can be performed becomes a normal level. On the other hand, in step S504, the reach mode is determined to be other than “low accuracy” in step S500, and it is determined to be other than “medium accuracy” in step S502. High accuracy ”. In this case, the main CPU 31a sets “53” as the reach determination value, and ends this subroutine. Thereby, the probability of being affirmative in the determination of whether or not reach performance can be performed increases.

  When the subroutine shown in FIG. 11 ends, the main CPU 31a proceeds to the process of step S401 shown in FIG. In step S401, the main CPU 31a acquires the reach determination random number updated as needed in the random number update process, and proceeds to the process in step S402. In step S402, the main CPU 31a determines whether or not the result of subtracting the reach determination value from the reach determination random number acquired in step S401 is a value smaller than zero. Note that the reach determination value is changed in the processes of steps S501, S503, and S504. When the result of subtracting the reach determination value from the reach determination random number becomes a value smaller than 0 (step S402: Y), the main CPU 31a proceeds to the process of step S403. On the other hand, when the result of subtracting the reach determination value from the reach determination random number is 0 or more (step S402: N), the main CPU 31a proceeds to the process of step S408.

  In step S403, the main CPU 31a clears the value of the post-reach fluctuation number (count value) added in step S409, which will be described later, and proceeds to the process of step S404. That is, in step S402, the determination of whether or not the reach effect can be performed is affirmative, and a lose reach effect is performed in the current symbol combination game. Therefore, the main CPU 31a clears the count value at this time. In step S404, the main CPU 31a determines whether or not the reach mode set in steps S406, S411, and S412 to be described later is “low probability”. That is, the main CPU 31a determines whether or not the reach mode flag is “0”. When the reach mode is “low probability” (step S404: Y), the main CPU 31a proceeds to the process of step S405. On the other hand, when the reach mode is not “low probability” (step S404: N), the main CPU 31a proceeds to the process of step S407. That is, in step S404, it is determined whether or not the player has won in the “low probability” state in the determination of whether or not the reach effect can be executed in the symbol combination game to be performed (step S402).

  In step S405, the main CPU 31a becomes affirmative in the determination of whether or not the reach effect can be executed in step S402, and the reach mode is determined to be “low probability” in step S404. Therefore, the main CPU 31a sets the variation pattern distribution table T1. Transition to processing. The variation pattern distribution table T1 is used in step S701 described later. In addition, when the variation pattern is determined from the variation pattern distribution table T1, that is, when the reach effect execution determination is affirmative, it is always super reach (reach with a high degree of reliability. Reach) is performed (see FIG. 4A).

  Note that when determining a variation pattern from the variation pattern distribution table T1, it is conceivable to perform not only super reach but also normal reach. However, if the reach effect is continuously performed, when the previous reach effect is executed, the reach mode is set to “low” in step S406 described later. The process is executed and the variation pattern distribution table T1 is set. For this reason, for example, after the super reach is performed in the previous reach production, the normal reach may be performed in the current reach production. In this case, the player's expectation for the big hit is reduced. However, in this embodiment, when the variation pattern is determined from the variation pattern distribution table T1, super reach is always performed, so that it is possible to prevent the player's sense of expectation from being lowered.

  In step S407, the main CPU 31a makes an affirmative in the determination of whether or not the reach effect can be executed in step S402. In step S404, the reach mode is not “low accuracy” (“medium accuracy” or “high accuracy”). Since the determination is made, the variation pattern distribution table T2 is set, and the process proceeds to step S406. When the variation pattern is determined from the variation pattern distribution table T2, normal reach or super reach is performed at a predetermined rate (see FIG. 4B).

  In step S406, the main CPU 31a sets the reach mode to “low probability”, and proceeds to the process of step S403. That is, the main CPU 31a sets the reach mode to “low probability” by inputting “0” to the reach mode flag. Therefore, the main CPU 31a performs a reach pattern in the current symbol combination game because it is determined affirmative in the determination of whether or not the reach effect can be executed in step S402. Accordingly, since the next change is “change immediately after reach”, the reach mode is set to “low” at this stage. As a result, in the next fluctuation, “1” is set as the reach determination value in step S501. Therefore, when the reach effect execution feasibility determination (step S402) is performed, the affirmative rate is low.

  In step S408, the main CPU 31a determines that the reach effect execution possibility determination in step S402 is negative, sets the variation pattern distribution table T3, and proceeds to the process in step S409. Note that, when a variation pattern is determined from the variation pattern distribution table T3, a normal variation pattern that is not a reach pattern is always performed (see FIG. 4C). In step S409, the main CPU 31a determines that the reach effect execution feasibility determination in step S402 is negative. Therefore, the main CPU 31a adds 1 to the number of changes after reaching (count value), and proceeds to step S410. In step S410, the main CPU 31a determines whether or not the number of changes after reach is 16 or more. When the number of fluctuations after reach is less than 16 (step S410: N), the main CPU 31a proceeds to the process of step S411. On the other hand, when the number of fluctuations after reach is 16 or more (step S410: Y), the main CPU 31a proceeds to the process of step S412.

  In step S411, the main CPU 31a sets the reach mode to “intermediate”, and proceeds to the process of step S413. That is, the main CPU 31a inputs “1” to the reach mode flag to set the reach mode to “medium”. In step S412, the main CPU 31a sets the reach mode to “high accuracy” and proceeds to the process of step S413. That is, the main CPU 31a sets the reach mode to “high accuracy” by inputting “2” to the reach mode flag. Note that the number of fluctuations after reach is 16 or more means that a symbol combination game (normal fluctuation) in which no reach effect is continuously performed 16 times or more after the previous reach effect is executed. is doing.

  Thereafter, the main CPU 31a proceeds to the process of step S413 (variation pattern determination process) and executes the subroutine shown in FIG.

  The subroutine shown in FIG. 12 includes the processes in steps S700 to S702. In step S700, the main CPU 31a acquires the random number for distributing the variation pattern, which is updated as needed in the random number update process, and proceeds to the process in step S701. In step S701, the main CPU 31a selects any one of the variation pattern distribution tables T1 to T4 set in steps S405, S407, and S408 and step S601 described later, the variation pattern distribution random number acquired in step S700, and Based on the above, the variation pattern is determined. Note that the variation pattern corresponding to the obtained random number for variation pattern distribution is different for each variation pattern distribution table T1 to T4 to be used (see FIGS. 4A to 4D).

  In the variation pattern distribution table T2, normal reach (either normal reach 1 or 2) is selected with a probability of 80/100, and super reach (any of super reach 1 to 5) is selected with a probability of 20/100. That is, when using the variation pattern distribution table T2 (when losing reach production is selected), normal reach is easily selected. In the variation pattern distribution table T4, normal reach (either normal reach 1 or 2) is selected with a probability of 20/100, and super reach (any of super reach 1 to 5) is selected with a probability of 76/100. Premier reach (either Premier reach 1 or 2) is selected with a probability of / 100. That is, when the variation pattern distribution table T4 is used (when the big hit effect is selected), the super reach is easily selected. Note that the premier reach is not selected when using the variation pattern distribution table T2 (when selecting the loss reach effect), but when using the variation pattern distribution table T4 (when selecting the jackpot effect). Selected only by For this reason, it is always a big hit when Premier Reach is executed. In other words, the premium reach is 100% reliable for the big hit. As described above, the probability of selecting each reach effect is different for each variation pattern distribution table, so that the reliability of the big hit is high in the order of “normal reach” <“super reach” <“premier reach”.

  Then, the main CPU 31a proceeds to the process of step S702. In step S702, the main CPU 31a outputs the variation pattern determined in step S701 as a variation pattern designation command to the sub CPU 33a of the display control board 33, the sub CPU 32a of the sound control board 32, and the sub CPU 34a of the lamp control board 34. This subroutine is finished.

  When the subroutine shown in FIG. 12 ends, the main CPU 31a proceeds to the process (design determination process) in step S414 shown in FIG. In step S414, the main CPU 31a determines a stop symbol (the symbol to be finally stopped) in the symbol combination game to be performed this time, and ends the present subroutine. If it is determined negative in the reach effect execution determination in step S402, the main CPU 31a determines the stop symbol so that the left symbol and the right symbol are different. In this case, the middle symbol is randomly determined unconditionally. If it is determined affirmative in step S402 whether or not the reach effect can be executed, the main CPU 31a determines that the left symbol and the right symbol to be stopped are the same symbol, and the middle symbol is the left symbol and the right symbol. Decide to be a different design.

  When the subroutine shown in FIG. 10 ends, the main CPU 31a ends the subroutine shown in FIG. 9, and proceeds to the process of step S104 shown in FIG.

  Further, when it is determined affirmative (big hit) in the jackpot determination of the step S302 shown in FIG. 9 and the process proceeds to the processing of the step S304 (big hit setting process), the main CPU 31a executes a subroutine shown in FIG. . The subroutine shown in FIG. 13 includes the processes in steps S600 to S602. The main CPU 31a proceeds to the process of step S600 (big hit symbol determination process). In step S600, the main CPU 31a determines a stop symbol (the symbol to be finally stopped) in the symbol combination game to be performed this time, and proceeds to the processing of step S601. If it is determined affirmative in the jackpot determination in step S302, the main CPU 31a determines the stop symbol so that the left symbol, the right symbol, and the middle symbol are the same symbol. In step S601, since the main CPU 31a is determined to be affirmative in the jackpot determination in step S302, the main CPU 31a sets the variation pattern distribution table T4 and proceeds to the processing in step S602. When the variation pattern is determined from the variation pattern distribution table T4, any one of normal reach, super reach, and premier reach is performed at a predetermined rate (see FIG. 4D). Next, the main CPU 31a proceeds to the process of step S602 (the variation pattern determination process) and executes the subroutine shown in FIG. That is, in step S602, the same process as in step S413 is performed. Then, the main CPU 31a ends this subroutine.

  When the subroutine shown in FIG. 13 is finished, the main CPU 31a finishes the subroutine shown in FIG. 9, and proceeds to the process of step S104 shown in FIG. In step S104, the main CPU 31a stands by until 4 ms elapses after the process of step S100 is started. After 4 ms elapses, the main CPU 31a proceeds to the process of step S100 again.

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

  (1) In the pachinko machine 10 according to the present embodiment, the number of times that the reach effect execution has been determined from the symbol combination game determined to be able to execute the reach effect until the next reach effect execution is determined, that is, reach. The reach effect is more likely to appear as the number of consecutive appearances of the symbol combination game that is lost without the effect being executed increases. Therefore, as a result that the situation where the reach effect does not appear over a long game is suppressed as much as possible, the appearance frequency of the reach effect becomes more appropriate. Therefore, the reach effect that appears moderately enables the player to maintain a sense of expectation for the big hit, thereby improving the interest of the game.

  Further, in the present embodiment, different factors for each pachinko machine 10 such as the number of reserved balls and the operating situation are not triggered by the probability change of the reach effect execution probability change means in the main CPU 31a. Variation in appearance frequency for each pachinko machine 10 is reduced. Therefore, the pachinko machine 10 that does not give the player a sense of incongruity can be obtained. Further, there is no problem that the difficulty in adjusting the nail is increased.

  (2) In this embodiment, as shown in FIG. 5, the reach winning probability is “1/241 (0.41%)” (low probability), “18/241 (7.47%)” (medium probability) ), “53/241 (21.9%)” (high probability). In this case, when the reach winning probability is set to the medium probability (see point B) and it is determined that the reach effect can be executed, in the symbol combination game immediately after the symbol combination game (see point A1), The setting is changed to the lowest probability with the lowest reach win probability. Further, when it is determined that the reach effect can be executed in a state where the reach winning probability is set to a high probability (see point C), in the symbol combination game immediately after the symbol combination game (see point A2), the reach is determined. The setting is changed to the lowest probability with the lowest winning probability. As described above, in the symbol combination game (points A1 and A2) immediately after the symbol combination game determined to be able to execute the reach effect, the probability is low, and as a result, the appearance frequency of the reach effect is the lowest. For this reason, it is possible to suppress as much as possible that the reach effect that results in the loss appears continuously several times (or appears frequently in a short time). As a result, it is possible to suppress giving a sense of expectation to the player as much as possible.

  In addition, you may change embodiment of this invention as follows.

  In the embodiment described above, step S403 is provided to clear the number of fluctuations after reach when it is determined that the reach (los reach reach) effect is executable during the lose setting process shown in FIG. A step similar to this may be provided during the big hit setting process shown in FIG. 13, and step S406 for setting the reach mode to “low probability” may be provided. According to this configuration, the reach winning probability is lowest in the symbol combination game immediately after the symbol combination game that has been a big hit, and as a result, it is difficult for the lose reach to occur immediately after the big hit.

  In the above embodiment, a step of determining whether “the number of fluctuations after reaching (count value) is 20 times or more” is provided between step S410 and step S412 shown in FIG. If the answer is affirmative, a step of setting the reach mode to “extremely accurate” may be provided. Moreover, what is necessary is just to make it transfer to step S412 in the case of negative at the step. In the above embodiment, since the reference count value is 16, the reference count value in the added step may be a number larger than 16, and is not particularly limited to 20 times. In other words, it may be a number larger than the reference count value used in step S410. Therefore, according to this configuration, even if the symbol combination game in which the reach effect is not executed continues 16 times or more, the reach effect is more likely to appear after 20 times. Of course, not only the step of determining whether “the number of fluctuations after reach (count value) is 20 times or more” is provided, but also “whether the number of fluctuations after reach (count value) is 30 times or more”. , “Whether the number of fluctuations after reaching (count value) is 40 times or more”, “Whether the number of fluctuations after reaching (count value) is 50 times or more”, and so on. A stage may be provided. Also, the reference count value is not limited to “20, 30, 40, 50...”, And may be another value that increases stepwise.

  In the loss setting process shown in FIG. 10, steps S404 and S407 are not essential and may be omitted.

  Next, in addition to the technical ideas described in the claims, the technical ideas grasped by the embodiment described above are listed below.
