Means (starting sensor (switch) SE1 shown in FIG. 3) are arranged.

  The second start port 13 is a winning port for entering a game ball when the start condition of the symbol variation game is established. In this embodiment, the second start port 13 is located to the right of the first start port 12. The second start port 13 is closed so that a game ball cannot be entered or is difficult to enter when a predetermined condition (ordinary symbol winning) is not satisfied. And the 2nd starting port 13 is opened so that a game ball can be made to enter or it can enter easily by establishment of predetermined conditions (winning of a normal symbol). The second start port 13 is opened by receiving power from an actuator (such as a solenoid or a motor). In this embodiment, the actuator that opens the second start port 13 is the actuator AC1 shown in FIG. In addition, a ball passage (not shown) that guides the game ball that has entered the ball to the back side of the game board YB is connected to the second start port 13, and the game ball that has entered the second start port 13 is connected to the ball passage. Means for detecting (start sensor (switch) SE2 shown in FIG. 3) is provided.

  The first big winning opening 14 is a winning opening through which a game ball is inserted when a payout condition for winning balls is established. In this embodiment, the first grand prize opening 14 is located on the lower right side of the effect display device 11 and is located downstream of the second major prize opening 15 in the flow path of the game ball. The first grand prize winning opening 14 is closed so that a game ball cannot be entered when a predetermined condition (winning a special symbol) is not established. Then, the first grand prize winning opening 14 is opened so that a game ball can be entered or it is easy to enter the ball upon establishment of a predetermined condition (winning a special symbol). The first grand prize opening 14 is opened by receiving power from an actuator (such as a solenoid or a motor). In this embodiment, the actuator that opens the first big winning opening 14 is the actuator AC2 shown in FIG.

  As shown in FIG. 4, a ball passage 16 that leads the game ball that has entered the ball to the back side of the game board YB is connected to the first grand prize opening 14. Means (a count sensor (switch) CS1 shown in FIG. 3) for detecting the game ball that has entered the mouth 14 is provided. In this embodiment, the count sensor CS1 corresponds to first detection means for detecting a game ball that has entered the first grand prize opening 14. Moreover, the 1st big prize opening 14 of this embodiment has the non-specific ball | bowl path 16a as a non-specific channel | path, and the specific ball | bowl channel | path 16b as a specific channel | path as the ball channel | path 16. The specific ball passage 16b is provided with means (a specific area sensor (switch) TS shown in FIG. 3) for detecting a game ball flowing into the specific ball passage 16b. In this embodiment, the specific area sensor TS corresponds to second detection means for detecting a game ball that has flowed into the specific ball path 16b, which is a specific path.

  In addition, as shown in FIG. 4, in the ball passage 16, the distribution of the game ball to either the non-specific ball passage 16 a or the specific ball passage 16 b is divided at the branch portion between the non-specific ball passage 16 a and the specific ball passage 16 b. A member 17 is disposed. In the pachinko gaming machine 10 according to this embodiment, the game balls distributed to the specific ball passage 16b are detected by the specific area sensor TS, whereby a condition for giving a probability variation state (probability variation state) described later is established. Note that the count sensor CS1 is disposed on the upstream side of the ball passage 16 with respect to the specific area sensor TS. For this reason, the count sensor CS1 detects all the game balls that have entered the first grand prize opening 14, while the specific area sensor TS detects only the game balls distributed to the specific ball path 16b.

  The sorting member 17 shown in FIG. 4 is a swing type provided with a swing piece. The swinging piece of the allocating member 17 blocks the entrance of the non-specific sphere passage 16a while blocking the entrance of the specific sphere passage 16b (the position indicated by the solid line in the figure), and the non-specific sphere passage 16a. It swings to a second position (a position indicated by a two-dot chain line in the drawing) that does not block the entrance but blocks the entrance of the specific ball passage 16b. The swing piece of the sorting member 17 operates by receiving power from an actuator (solenoid, motor, etc.). In this embodiment, the actuator that operates the swing piece of the sorting member 17 is the actuator AC4 shown in FIG. In the swing type sorting member 17, when the swing piece is in the first position (solid line), the specific ball passage 16b can take an allowable state in which a game ball can enter, while the non-specific ball passage 16a. Can take a non-permissible state in which game balls are not allowed to enter. Further, in the swing type sorting member 17, when the swing piece is in the second position (two-dot chain line), the specific ball passage 16b can be in a non-permissible state in which game balls are not allowed to enter, The non-specific ball passage 16a can be in a permissible state that allows a game ball to enter.

  The sorting member 17 includes, for example, a vero type swing member in addition to the swing type described above. The tongue-type rocking member has a tongue that can be projected and retracted on the passage, and when the tongue is in a protruding state, for example, by closing the entrance of the specific ball passage 16b, it is impossible to enter the game ball, The game ball is guided to the non-specific ball passage 16a. In addition, when the tongue piece is in the sunk state, the Vero type swinging member enables (allows) the entry of the game ball by opening the entrance of the specific ball passage 16b, for example, and allows the game ball to enter the specific ball passage 16b. It is configured to guide.

  The second major winning opening 15 is a winning opening through which a game ball is inserted when a payout condition for winning balls is established. In this embodiment, the second big prize opening 15 is located on the upper right side of the effect display device 11. The second big prize opening 15 is closed so that a game ball cannot be entered when a predetermined condition (winning of a special symbol) is not established. Then, the second grand prize winning opening 15 is opened so that a game ball can be entered or it is easy to enter the ball upon establishment of a predetermined condition (a special symbol win). The second big prize opening 15 is opened by receiving power from an actuator (solenoid, motor, etc.). In this embodiment, the actuator that opens the second big prize opening 15 is the actuator AC3 shown in FIG. In addition, a ball passage (not shown) that guides the game ball that has entered the ball to the back side of the game board YB is connected to the second grand prize opening 15, and the game that has entered the second big prize opening 15 is provided in the ball passage. A means for detecting a sphere (count sensor (switch) CS2 shown in FIG. 3) is provided. In this embodiment, the count sensor CS <b> 2 corresponds to third detection means for detecting a game ball that has entered the second grand prize opening 15.

  The big hit game is performed a plurality of times with a predetermined number of rounds as the upper limit for a round game that allows a game ball to enter the first grand prize port 14 or the second big prize port 15. When a big hit game is generated, an opening time is set before the first round game is started, and an opening effect indicating the start of the big hit game is performed during the opening time. When a big hit game is generated, an ending time is set when the final round game is finished, and an ending effect indicating the end of the big hit game is performed during the ending time.

  Further, as shown in FIG. 2, an operation gate 18 is provided in the game area YBa. In this embodiment, the operation gate 18 is an area on the right side of the game area YBa and is located above the second start opening 13 and the first grand prize winning opening 14. The operating gate 18 is opened with a gate port 18a that is opened so that a game ball can be always entered. A means (gate sensor (switch) GS shown in FIG. 3) for detecting a game ball entering and passing through the gate is provided at the gate port 18a. The gate port 18a of the operation gate 18 is a entrance for allowing a game ball to enter when the start condition of the normal symbol variation game using the normal symbol is satisfied. The second starting port 13 wins the normal symbol winning lottery performed by the game ball entering the operating gate 18 and is released from the closed state after the normal symbol winning symbol is derived in the normal symbol variation game. Operate to state.

  In this embodiment, the first start port 12, the second start port 13, the first big winning port 14, and the second big winning port 15 described above are ball entry devices that are targeted for paying out a prize ball by entering a game ball. Yes, a prize ball payout condition is established by entering a game ball. On the other hand, the actuating gate 18 is not a pitching device that is a target for paying out a prize ball by entering a game ball, and a prize ball payout condition is not satisfied even if a game ball enters.

  In this embodiment, the player divides the game ball into the left region and the right region by adjusting the strength of the firing strength of the launch handle HD, and the first start port 12, the second start port 13. It becomes possible to enter the game ball into the first grand prize opening 14, the second big prize opening 15, or the operation gate 18. Specifically, when the game ball is fired by adjusting the firing strength to be strong (so-called right-handed), the game ball is easily guided to flow down to the right region, and the second start port 13, the first large There is a possibility of entering the winning opening 14, the second large winning opening 15, or the operation gate 18. It should be noted that the right strike is performed by adjusting the firing strength to a maximum strength or slightly weaker than the maximum strength because it is necessary to launch the game ball vigorously in order to reach the right region.

  On the other hand, when the game ball is fired by adjusting the firing strength to be weak (so-called “left-handed”), the game ball is likely to flow down to the left area and may enter the first start port 12. is there. In addition, the left strike does not require the game ball to be fired as vigorously as the right strike, and is adjusted to such an intensity that the fired game ball does not reach the right region. In this embodiment, the game ball flow path is formed by game parts such as game nails so that the game ball cannot enter the first start port 12 when the player makes a right turn. The gaming parts may be arranged so as to restrict entry into the first start opening 12 when making a right hit, or enter the first start opening 12 as compared to when making a left hit. It may be arranged so that it is difficult to make a ball (the probability of entering a ball is extremely low).

  In this embodiment, the “left region” is a region located on the left side of the center line C that bisects the game region YBa left and right when the game board YB is viewed from the front. In this embodiment, the “right region” is a region located on the right side of the center line C when the game board YB is viewed from the front. The game ball launched by the operation of the launch handle HD in the pachinko gaming machine 10 is guided by the launch passage 19 located on the left side when the game board YB is viewed from the front, and is prevented from returning backwardly in the launch passage 19. The game area YBa is reached through the valve 20. For this reason, the “left region” is also a region closer to the launch passage 19, and conversely, the “right region” is also a region away from the launch passage 19. Then, the game ball guided down in the left area passes through the left side of the effect display device 11 located in the game area YBa and heads to the out port 21. Also, the game ball guided down the right area passes through the right side of the effect display device 11 located in the game area YBa and goes to the out port 21. In addition, as shown in FIG. 2, the out port 21 is located, for example, in the lowermost part of the game area YBa.

  The game board YB is provided with special symbol display devices 23a and 23b, hold display devices 24a and 24b, and a normal symbol display device 25 shown in FIG. These display devices are located in a portion of the game board YB that can be viewed by the player when the pachinko gaming machine 10 is viewed from the front. For example, these display devices are arranged on a decorative member arranged in the game area of the game board YB, a corner decorative member of the game board YB, or the like.

  The special symbol display devices 23a and 23b perform a symbol variation game using the special symbol, and a special symbol corresponding to the lottery result of the big hit lottery is derived in the symbol variation game. The special symbol display device 23a is a display device that performs a symbol variation game of a first special symbol, and the special symbol display device 23b is a display device that performs a symbol variation game of a second special symbol. When a game ball enters the first start port 12 and is detected, the start condition for the symbol variation game of the first special symbol is satisfied. On the other hand, when a game ball enters the second start port 13 and is detected, the start condition of the symbol variation game of the second special symbol is satisfied. In the first special symbol and the second special symbol, a big hit lottery is performed when the start condition is established, and the probability of winning the big hit lottery is the same probability. In addition, in the first special symbol and the second special symbol, the advantage of winning the jackpot lottery by changing the type of jackpot determined when winning the jackpot lottery or the same type of jackpot determination ( For example, the number of winning balls, the period during which the entrance rate improvement state is given, etc.) may be varied.

  When the starting condition is satisfied, the special symbol display device 23a or the special symbol display device 23b performs a special symbol variation game in order to derive the lottery result of the big hit lottery, and is derived in the symbol variation game. The symbol variation game for deriving the result according to the special symbol is also performed on the effect display device 11 using the decorative symbol.

  The special symbol display devices 23a and 23b are display devices including a light emitter. In the special symbol variation game, a combination of arbitrary light emitters constituting the display device is derived as a special symbol. The special symbols include a jackpot symbol that is derived when the jackpot lottery is won and a loss symbol that is derived when the jackpot lottery is not won.

  On the other hand, the effect display device 11 derives an effect symbol that can recognize the result of the symbol variation game by a combination of a plurality of identification information (identification information in three columns in the embodiment). In this embodiment, the identification information constituting the combination of effect symbols is composed of a design imitating Arabic numerals. For example, the identification information of each column is an Arabic numeral from [1] to [9]. As a result, for example, the combination of effect symbols is a combination such as [111] in which the identification information of all columns is the same, or a combination of [479], [337], and [121] in which the identification information of all the columns is not the same. become. Then, the result of the symbol variation game of the production symbol corresponds to the result of the symbol variation game of the special symbol. For this reason, when the big hit symbol is derived in the special symbol variation game, the combination of the identification information in all the columns is derived in the effect symbol variation game, and the big hit can be recognized. On the other hand, when a shift symbol is derived in the special symbol variation game, a combination in which the identification information of all the columns is not the same identification information is derived in the effect symbol variation game, and the shift can be recognized. The symbol variation game of the first special symbol and the symbol variation game of the second special symbol are not executed at the same time, and the effect display device 11 performs the symbol variation game of the effect symbol corresponding to the special symbol being executed.

  The hold display device 24a is a display device that displays the number of symbol variation games (starting hold number) of the first special symbol that is suspended, and the hold display device 24b is the second special symbol that is suspended. It is a display device that displays the number of symbol variation games (starting suspension number). The normal symbol display device 25 plays a normal symbol variation game using a normal symbol, and in the normal symbol variation game, a normal symbol corresponding to the lottery result of the normal symbol winning lottery is derived.

  Moreover, the pachinko gaming machine 10 of this embodiment has a probability variation function. The probability variation function is a function that can give a probability variation state (hereinafter referred to as “probability variation state”) that changes the winning probability of the big hit lottery from a low probability (normal probability) to a high probability after the end of the big hit game. . The probable change state is a game state that is easier to win the big hit lottery and is advantageous to the player than the non-probability change state (hereinafter referred to as “non-probable change state”) in which the win probability of the big win lottery is low. .

  In the pachinko gaming machine 10 of this embodiment, the game ball that has entered the first big winning opening 14 in the specific round game among the round games constituting the jackpot game and the flow of the game ball that has flowed into the specific ball passage 16b is the specific area sensor TS. It is a pachinko gaming machine (V probability changing machine) that gives a probability variation state after the end of the big hit game on condition that it is detected. In other words, the V probability change machine is a pachinko gaming machine that does not give a probability change state after the end of the big hit game, and enters a non-probability change state after the end of the big hit game when the specific area sensor TS does not detect the game ball. is there. In other words, when a game ball is not detected by the specific area sensor TS, the V probability change machine does not enter a probability change state even after the big hit game ends, and enters a non-probability change state. During the big hit game, the non-probability change state and the non-entrance rate are improved. For this reason, when a game ball is not detected by the specific area sensor TS in the V probability variation machine, the non-probability variation state is maintained after the end of the big hit game.

  The V probability change machine has a plurality of types of jackpots, but these jackpots, for example, by changing the opening pattern of the first big winning opening 14 in a specific round game, the inflow to the specific ball passage 16b It makes a difference in ease. For example, in a specific round game in the first big hit game, the first big winning opening 14 operates in a long open pattern so that it easily flows into the specific ball passage 16b. On the other hand, in the specific round game in the second big hit game, the first big winning opening 14 flows into the specific ball passage 16b by operating in the short open pattern in which the open time during the specific round game is short compared to the long open pattern. It is difficult to do. In this embodiment, the first big prize opening 14 is a big prize opening opened in a specific round game, and the second big prize opening 15 is a big prize opening opened in a non-specific round game other than the specific round game. It is. The above-described method for changing the ease of inflow of the game ball into the specific ball passage 16b is an example, and the method can be arbitrarily changed.

  In addition, the pachinko gaming machine 10 of this embodiment is a pachinko gaming machine (falling lottery machine) that shifts the gaming state from the probabilistic state to the non-probable changing state by winning the falling lottery to drop the probable state into the non-probable state ). In other words, the falling lottery machine is a pachinko gaming machine in which the probability variation state is continued until the falling lottery is won. The falling lottery machine can be terminated by establishing an end condition (winning for the falling lottery) different from the condition for winning the big hit lottery for the probability variation state given after the end of the big hit game.

  In addition, the pachinko gaming machine 10 of this embodiment has a ball entry rate improving function. The entrance rate improvement function is a function that can provide an entrance rate improvement state in which the entrance rate of game balls per unit time to the second start port 13 as a predetermined entrance is improved. The entrance rate improvement state is a so-called “electric support state” or “high base state”. In the following description, a state where the entrance rate improvement state is not given may be referred to as a “non-entrance rate improvement state”. The non-entrance rate improvement state is a so-called “non-electric support state” or “low base state”.

  The entrance rate improvement state can be realized, for example, by executing one control arbitrarily selected from the following four controls, or executing a combination of a plurality of controls. The first control is normal symbol variation time shortening control in which the variation time of the normal symbol variation game is shorter than that in the non-entrance rate improvement state. The second control is a normal symbol probability variation control in which the probability of winning a normal symbol winning lottery (ordinary winning probability) is varied with a higher probability than in the non-entrance rate improvement state. The third control is an open time extension control in which the total opening time of the second start port 13 based on winning the normal symbol winning lottery is made longer than that in the non-entrance rate improvement state. As the opening time extension control, the number of times of opening the second start port 13 based on the fact that the normal symbol winning lottery is won is larger than that in the non-entry rate improvement state, and the normal symbol winning lottery It is preferable to execute at least one of the controls for making the one opening time of the second start port 13 based on having won the game longer than that in the non-entrance rate improvement state. The fourth control is special symbol variation time shortening control that makes the variation time (for example, average variation time) of the special symbol variation game easier to be shorter than in the non-entrance rate improvement state. When the special symbol variation time reduction control is executed, the entrance rate improvement state is a so-called “variation time reduction state”.

  In this embodiment, regardless of whether the entrance rate improvement state is a probability variation state or a non-probability variation state, a special symbol variation game of a predetermined number of times (in this embodiment, 100 times) is executed. Is granted. When the probability variation state is continued even when the specified number of times is reached, the probability variation state is continuously given until the probability variation state continues, that is, until the falling lottery is won. It should be noted that the entrance rate improvement state ends when the big hit lottery is won. In the case of the pachinko gaming machine 10 using the first special symbol and the second special symbol, the specified number of times is the total number of times of the symbol variation game of the first special symbol and the symbol variation game of the second special symbol.

The pachinko gaming machine 10 is mounted with various boards including a main control board 30 and a sub control board 31 shown in FIG.
The main control board 30 can write and read necessary data, and a main control CPU 30a capable of executing control operations in a predetermined procedure, a main control ROM 30b storing a control program for the main control CPU 30a, and the like. Main control RAM 30c. The main control board 30 has a random number generation circuit 30d.

  The main control CPU 30a receives detection signals from various sensors SE1, SE2, CS1, CS2, GS, and TS. The main control CPU 30a controls display contents of various display devices (special symbol display devices 23a and 23b, hold display devices 24a and 24b, normal symbol display device 25, etc.) and controls the operations of the actuators AC1 to AC3. Control.

  The information stored in the main control ROM 30b includes a main control program for executing processing related to a game, information for specifying a special symbol variation pattern (main variation pattern), various determination values, and the like. The variation pattern of the special symbol can specify a variation time (effect time) from when the special symbol starts to vary until the special symbol is confirmed and stopped. The main variation pattern can be classified into a variation pattern for big hit variation and a variation pattern for outlier variation. The big hit variation is an effect performed when the big hit lottery is won, and in the special symbol changing game, the big hit symbol is finally derived. The loss variation is an effect that is performed when the big win lottery is not won, and in the special symbol variation game, the loss symbol is finally derived. Note that the deviation variation includes a variation that is lost when the reach effect is performed in the effect symbol design variation game, and a variation that is lost when the reach effect is not performed in the effect symbol design variation game. The various determination values include a big hit determination value used for the big hit lottery, a normal hit determination value used for the normal hit lottery, a fall determination value used for the falling lottery, and the like. The main control RAM 30c stores various types of information (random values, timer values, flags, start pending numbers, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine 10.

  The main control CPU 30a executes random number update processing (software random number generation processing) in which various software random number values are updated every predetermined control cycle (interrupt cycle) and stored in the main control RAM 30c. The software random number includes a big hit symbol random number used when determining a big hit symbol of a special symbol, a variation pattern distribution random number used when distributing a variation pattern, and the like. The random number generation circuit 30d generates a hardware random number by updating one value for each cycle of an internal system clock (for example, 10 MHz) supplied from a clock circuit (not shown) mounted on the microprocessor. The hardware random numbers include a big hit random number used for a special symbol jackpot lottery, a normal hit random number used for a normal symbol hit lottery, a falling lottery random number used for a falling lottery, and the like.

  As shown in FIG. 3, the sub control board 31 is electrically connected to the main control board 30 so that control information (control signal) is transmitted from the main control board 30 in one direction. The sub-control board 31 includes a sub-control CPU 31a as control means capable of executing a control operation in a predetermined procedure, a sub-control ROM 31b for storing a control program for the sub-control CPU 31a, and writing of necessary data. A sub-control RAM 31c capable of reading.

  The sub control CPU 31 a of the sub control board 31 performs control according to the control information based on the control information (control command) transmitted from the main control board 30. For example, when starting the special symbol changing game, the main control CPU 30a provides control information for instructing the start of the change (start of the game) in addition to the control of the display contents of the special symbol display devices 23a and 23b. It transmits to control CPU31a. Receiving the control information, the sub-control CPU 31a controls the display contents so that the effect display device 11 can play the symbol variation game of the effect symbols. Further, the sub control CPU 31a controls the lighting / non-lighting of various decoration lamps La provided on the frame of the pachinko gaming machine 10 and the game board YB and the sound output of the speaker Sp. The effect by the decoration lamp La and the speaker Sp is performed in accordance with the symbol variation game of the effect symbol, or is performed in a standby state.

Hereinafter, processing (normal processing) performed by the main control CPU 30a of the main control board 30 to control the game will be described.
First, processing (reception processing (input processing)) related to reception of gaming ball detection signals from various sensors SE1, SE2, CS1, CS2, GS, and TS will be described.

  When the main control CPU 30a receives the detection signal from the start sensor SE1 by entering the first start port 12, the number of start suspensions of the first special symbol is less than the upper limit number (4 in this embodiment). Determine if there is. Then, the main control CPU 30a rewrites the start hold number by adding 1 when the start hold number of the first special symbol is less than the upper limit number, and displays the hold start number 24a after the addition. To control.

  Further, when the main control CPU 30a receives the detection signal from the start sensor SE2 by entering the second start port 13, the start reserved number of the second special symbol is the upper limit number (4 in this embodiment). It is determined whether it is less than. The main control CPU 30a then rewrites the start hold number by adding 1 when the start hold number of the second special symbol is less than the upper limit number, and displays the hold start number 24b after the addition. To control.

  Note that the main control CPU 30a does not add the start hold number when the start hold number reaches the upper limit number. On the other hand, when adding the number of start suspension, the main control CPU 30a transmits information (such as a hold designation command) that can specify the number of start suspension after the addition to the sub-control board 31. The sub-control CPU 31a that has received the information that can specify the number of start suspensions causes the effect display device 11 to display an image that indicates the number of start suspensions that can be specified from the information.

  In addition, when a game ball enters with less than the upper limit number of starting suspensions, the main control CPU 30a can acquire various random number values when triggered and can specify the acquired various random number values. The random number information is stored in the main control RAM 30c. The random number information may be constituted by a random number value, or may be constituted by information obtained by converting the random number value into other information that can identify the value. Further, when storing the random number information, the main control CPU 30a stores the order of entering the game balls (information storage order) that triggered the acquisition of the value of the random number, and the order of entering the game balls that have entered previously. The information is stored in the main control RAM 30c so that (information storage order) can be specified. When acquiring a random number value, the main control CPU 30a acquires a big hit random number value or a falling lottery random number value from the random number generation circuit 30d, and uses the big hit symbol random number value or the fluctuation pattern distribution random number value as the main random number value. Obtained from the control RAM 30c.

  Further, the main control CPU 30a performs a prize ball process for paying out a predetermined number of prize balls in a process when receiving detection signals from the start sensors SE1 and SE2 and the count sensors CS1 and CS2. In the prize ball process, a payout designation command (payout signal) to be transmitted to a payout control board (not shown) provided in the pachinko gaming machine 10 is generated and transmitted. The payout control board that has received the payout designation command operates a ball payout device (not shown) included in the pachinko gaming machine 10 to pay out a predetermined number of game balls as prize balls.

  In addition, the main control CPU 30a acquires various random numbers used for processing for storing the holding of the normal symbol variation game using the normal symbol, normal lottery, etc. in the processing when the detection signal from the gate sensor GS is received. Process. In addition, the main control CPU 30a can specify that the probability change state is given after the end of the jackpot game in the processing when the detection signal from the specific area sensor TS is received in the specific round game of the jackpot game ( Flag, etc.) is stored in the main control RAM 30c.

  Next, processing related to the execution of the special symbol variation game for deriving the lottery result of the big hit lottery (special diagram variation processing) will be described. The main control CPU 30a executes the special figure changing process at every predetermined control cycle (for example, 4 ms).

  In the special symbol variation process, the main control CPU 30a determines whether or not the special symbol variation game start condition is satisfied. In this determination, the main control CPU 30a determines that the start condition is satisfied when the special symbol changing game is not being executed and when the big hit game is not being executed, while the special symbol changing game is being executed. Alternatively, it is determined that the start condition is not satisfied when the big hit game is being played. Then, when the start condition is not satisfied, the main control CPU 30a ends the special figure changing process.

  When the above-described start condition is satisfied, the main control CPU 30a reads the number of start suspensions of the second special symbol, and determines whether the read start suspension number is greater than zero. Then, when the number of reserved start of the second special symbol is larger than zero, the main control CPU 30a performs a predetermined process so as to start the symbol variation game of the second special symbol. On the other hand, the main control CPU 30a reads the start hold number of the first special symbol when the start hold number of the second special symbol is zero, and determines whether the read start hold number is larger than zero. When the number of reserved start of the first special symbol is larger than zero, the main control CPU 30a performs a predetermined process so as to start the symbol variation game of the first special symbol. The pachinko gaming machine 10 of this embodiment has a specification in which the symbol variation game of the first special symbol and the symbol variation game of the second special symbol are not executed simultaneously, and the symbol variation game of the second special symbol is preferentially executed. is there.

  When both the number of reserved start of the first special symbol and the number of reserved start of the second special symbol are zero, the main control CPU 30a executes a demonstration effect (hereinafter referred to as “demo effect”). Process. The demonstration effect is an effect for notifying that the pachinko gaming machine 10 is in a standby state by using a device such as the effect display device 11 and obtaining a customer effect.

  When starting the symbol variation game of the second special symbol, the main control CPU 30a rewrites the number of the reserved start of the second special symbol by 1 and rewrites it, and also displays the number of the reserved suspension after subtraction 24b. To control. In addition, when subtracting the start suspension number, the main control CPU 30a transmits information (such as a hold designation command) that can specify the start suspension number after subtraction to the sub-control board 31.

Next, the main control CPU 30a acquires the random number information stored first in the random number information stored in the main control RAM 30c.
The CPU 30a for main control that has acquired the random number information first compares the value of the falling lottery random number with the falling determination value, and performs the falling lottery. The probability of winning the falling lottery is a fixed probability, for example, about 1/500. The probability of winning the falling lottery can be defined by the ratio of the number of values (falling judgment value) to be won by “falling” with respect to the numerical value that the random number for falling lottery can take. In addition, the falling lottery may be performed when the time when the special figure variation process is executed is in a probable variation state, or it may be performed even in a non-probability variation state. Also good.

  Then, when the main control CPU 30a wins the falling lottery when it is in the probability changing state, the main control CPU 30a changes information (for example, a management flag) that can specify the gaming state from information indicating the probability changing state to information indicating the non-probability changing state. . On the other hand, if the main control CPU 30a does not win the falling lottery when it is in the probability changing state, the main control CPU 30a maintains the information indicating the gaming state as information indicating the probability changing state. Information that can specify the game state is stored in the main control RAM 30c.

  Next, the main control CPU 30a compares the jackpot random number specified from the acquired random number information with the jackpot determination value, and performs a jackpot lottery. In the big hit lottery, the main control CPU 30a determines whether the big hit lottery (that is, when the special figure variation process is executed) is in a probable variation state or a non-probable variation state based on information that can specify the gaming state. Then, based on the determination result, the big win lottery is performed with different winning probabilities.

  The winning probability of the jackpot lottery can be defined by the ratio of the number of values to be won in the jackpot (the jackpot determination value) with respect to the numerical value that the jackpot random number can take. In other words, the winning probability of the jackpot lottery can be increased by increasing the number of values to win the jackpot. The winning probability in the non-probable state (low probability) is set to about 1/230, for example, and the winning probability in the probabilistic state (high probability) is set to, for example, about 1/100.

  In the big hit lottery, the main control CPU 30a determines whether the value of the big hit random number acquired from the main control RAM 30c matches the big hit determination value. When the value of the big hit random number matches the big hit determination value, the big hit lottery is won. When the big hit lottery is won, the main control CPU 30a performs a big hit process. Specifically, the main control CPU 30a determines the jackpot symbol of the special symbol based on the jackpot symbol random number specified from the acquired random number information. The determined jackpot symbol becomes a fixed stop symbol derived in the special symbol variation game. The jackpot symbol of the special symbol is associated with the type of jackpot. For this reason, determining the jackpot symbol determines the type of jackpot. In this embodiment, the main control CPU 30a functions as a jackpot type determining means for determining the jackpot type when the jackpot lottery is won. Further, the main control CPU 30a determines a variation pattern from the variation patterns for the big hit variation that can be selected when the big hit is won based on the value of the variation pattern distribution random number specified from the acquired random number information.

  Further, the main control CPU 30a performs a loss process when the big hit lottery is not won. In the detachment process, the main control CPU 30a determines a special symbol detachment symbol. The decided off symbol becomes the fixed stop symbol derived in the special symbol variation game. Further, the main control CPU 30a determines a variation pattern for deviation variation based on the value of the variation pattern distribution random number specified from the acquired random number information. When determining a variation pattern for deviation variation, the main control CPU 30a determines either a variation pattern with reach or a variation pattern without reach.

  In addition, when starting the symbol variation game of the first special symbol, the main control CPU 30a performs control similar to the control of the second special symbol described above on the first special symbol. In other words, the main control CPU 30a performs subtraction processing or loss processing based on the results of the subtraction of the number of start suspensions of the first special symbol, the falling lottery, the big hit lottery, and the big hit lottery.

  Also, the main control CPU 30a, as processing related to the execution of the special symbol variation game, is based on the result of the above-described processing, and control information for instructing the sub control CPU 31a of the sub control board 31 to control the game effect ( Control command) is generated. Various control information generated by the process is transmitted to the sub control CPU 31a at a predetermined timing by a command transmission process performed by the main control CPU 30a.

  When starting the symbol variation game with a special symbol, the main control CPU 30a generates a variation start command (variation start information) that can specify that the symbol variation game is started as control information. The fluctuation start command also includes information that can identify the fluctuation pattern determined in the above-described jackpot process or off-line process. Further, the main control CPU 30a generates a special symbol command (special symbol information) that can specify a special symbol as control information when starting a special symbol variation game. Since the jackpot symbol of the special symbol corresponds to the type of jackpot, the type of jackpot can be specified by the special symbol information. For this reason, the special figure command is information that can specify whether or not the game is successful, and information that can specify the type of jackpot.

  In addition, when the elapsed time since the start of the special symbol variation game reaches a predetermined variation time (the time set in the variation pattern), the main control CPU 30a uses the special symbol variation as the control information. A change stop command (change end information) that can specify that the game is to be ended is generated. In addition, when starting the symbol change game of the special symbol, the main control CPU 30a displays the display content of the special symbol display device 23a or the special symbol display device 23b so as to start the change of the first special symbol or the second special symbol. Control and start measuring variation time. Then, the main control CPU 30a controls the display content of the special symbol display device 23a or the special symbol display device 23b so as to derive the determined special symbol when the variation time set in the determined variation pattern has elapsed. To do.

Next, a process related to the progress of the big hit game performed by winning the big hit lottery will be described.
The jackpot game of this embodiment is composed of an opening at the start of the jackpot game, a round game that opens the first jackpot 14 or the second jackpot 15, and an ending at the end of the jackpot game. Yes. In other words, the big hit game progresses step by step from opening to round game to ending. Then, the main control CPU 30a generates a control information (control command) for instructing the sub control CPU 31a of the sub control board 31 to control the game effect as a process related to the progress of the big hit game, and a first big prize opening 14 or the second grand prize opening 15 is opened and closed. Various control information generated in the above process is transmitted to the sub control CPU 31a at a predetermined timing by a command transmission process performed by the main control CPU 30a.

  When starting the opening, the main control CPU 30a generates an opening command as control information. The opening command is transmitted to the sub control CPU 31a at the start of the opening. The main control CPU 30a generates a release command as control information when starting one round game, and generates a close command as control information when ending one round game when the end condition is satisfied. To do. The release command is transmitted to the sub control CPU 31a at the start of the round game, and the close command is transmitted to the sub control CPU 31a at the end of the round game.

  The main control CPU 30a controls the actuator AC3 to the first state (for example, the excited state) and closes the second big prize opening 15 when the second big prize opening 15 is opened in a round game other than the specific round game. In the case of making it, the actuator AC3 is controlled to the second state (for example, a non-excitation state). In this embodiment, the end condition of the round game other than the specific round game is that a predetermined upper limit number of balls (for example, 8 balls) has been entered, or the opening time of the second big prize opening 15 is predetermined. One of the above-mentioned cases has been reached.

  On the other hand, the main control CPU 30a controls the actuator AC2 to the first state (for example, the excited state) and closes the first big prize opening 14 when opening the first big prize opening 14 in a specific round game. The actuator AC2 is controlled to the second state (for example, the non-excited state). In this embodiment, a specific round game end condition is that a predetermined upper limit number of balls (for example, 8 balls) has been entered, or the opening time of the first big winning opening 14 (depending on the type of jackpot) Has reached a predetermined upper limit time. In addition, the main control CPU 30a controls the actuator AC4 and controls the operation of the sorting member 17 in a specific round game. That is, in the main control CPU 30a, the distribution member 17 is in the first position (the specific ball passage 16b is in an allowable state (solid line in FIG. 4)) or in the second position (the non-specific ball passage 16a is in an allowable state (two in FIG. 4). The operation is controlled so that a dotted line)) can be taken. In this embodiment, the main control CPU 30 a functions as an operation control unit that controls the operation of the sorting member 17. In this embodiment, the main control CPU 30a operates the distribution member 17 in the same operation pattern in the first jackpot game and the second jackpot game. On the other hand, the main control CPU 30a varies the opening pattern of the first big winning opening 14 between the first big hit game and the second big hit game. Thus, there is a difference in the ease of entering the game ball into the specific ball passage 16b between the first big hit game and the second big hit game. In this embodiment, the first big hit game has a very high probability (almost 100%) and the game ball flows into the specific ball passage 16b, and the second big hit game has an extremely high probability (almost 100%). The opening pattern of the first big winning opening 14 is set so as not to flow into the passage 16b.

  Further, the main control CPU 30a generates an ending command as control information when starting the ending after the end of the last round game. The ending command is transmitted to the sub control CPU 31a at the start of ending.

Next, processing related to the gaming state will be described.
In this process, the main control CPU 30a generates control information that can specify the gaming state as control information. Various control information generated in the above process is transmitted to the sub control CPU 31a at a predetermined timing by a command transmission process performed by the main control CPU 30a.

  The main control CPU 30a generates a state 1 designation command (gaming state information) as a state designation command that can specify the gaming state when the gaming state is in a non-probability changing state and the non-entrance rate improving state. Further, when the gaming state is in the probable change state and the entrance rate improvement state, the main control CPU 30a generates a state 2 designation command (gaming state information) as a state designation command that can specify the gaming state. In addition, when the gaming state is in a non-probable change state and the entrance rate improvement state, the main control CPU 30a generates a state 3 designation command (gaming state information) as a state designation command that can specify the gaming state. Further, when the gaming state is in the probabilistic state and the non-entrance rate improving state, the main control CPU 30a generates a state 4 designation command (gaming state information) as a state designation command that can specify the gaming state. In addition, when managing the period of giving the entrance rate improvement state by the number of games, the main control CPU 30a counts the number of times the special symbol variation game that has been executed is executed, and the exit condition for the entrance rate improvement state is satisfied. Sometimes an end command (game state information) is generated as a state designation command that can specify the end of the entrance rate improvement state.

  The generated gaming state information is transmitted to the sub control CPU 31a, for example, when the power is turned on (when power is restored) or when the gaming state is changed. For example, when the gaming state after the end of the big hit game is set to the probability changing state and the entrance rate improving state, the state 2 designation command is transmitted to the sub control CPU 31a with the end of the big hit game. The game state information is not limited to the exemplified control information, and is set for each game state that needs to be recognized by the sub control CPU 31a.

Next, a process related to the execution of the normal symbol variation game for deriving the lottery result of the normal symbol winning lottery (normal diagram variation process) will be described.
In the normal symbol variation process, the main control CPU 30a determines whether the start condition of the normal symbol variation game is satisfied. In this determination, the main control CPU 30a determines that the start condition is satisfied when the normal symbol variation game is not being executed and when the normal symbol hitting game is not being played, while the normal symbol variation game is being executed, or It is determined that the start condition is not satisfied when the normal symbol hit game is being played. Then, when the start condition is not satisfied, the main control CPU 30a ends the normal map changing process.

  When the above-described start condition is satisfied, the main control CPU 30a reads the normal design start hold number, and determines whether the read normal design start hold number is greater than zero. Then, when the start suspension number is larger than zero, the main control CPU 30a performs a predetermined process so as to start the normal symbol variation game. On the other hand, the main control CPU 30a terminates the routine change process when the number of start suspensions is zero.

  When starting the normal symbol variation game, the main control CPU 30a rewrites the start suspension number by one. Then, the main control CPU 30a acquires the first stored random number information among the random number information (normal random numbers) stored in the main control RAM 30c. Then, the main control CPU 30a compares the normal hit random value specified from the acquired random number information with the normal hit determination value, and performs the normal hit lottery. The pachinko gaming machine of this embodiment has a ball entry rate improving function. For this reason, in the normal winning lottery, the main control CPU 30a performs the normal winning lottery with different winning probabilities depending on whether the normal winning lottery is in the improved entrance rate or in the non-entry rate improved state.

  In this embodiment, the winning probability in the non-entry rate improvement state is set low (close to 0%), and the winning probability in the entering rate improvement state is set high (close to 100%). Note that the winning probability of the normal winning lottery can be defined by the ratio of the number of values won per normal (ordinary winning determination value) with respect to the numerical value that the normal winning random number can take.

  Returning to the explanation of the normal fluctuation processing, in the normal winning lottery, the main control CPU 30a determines whether the value of the normal hit random number acquired from the main control RAM 30c matches the normal hit determination value. If the normal hit random number value matches the normal hit determination value, the normal hit lottery is won. When the normal winning lottery is won, the main control CPU 30a performs the normal winning process. In the normal hit process, the main control CPU 30a determines a normal symbol hit pattern and also determines a normal symbol variation pattern that can specify the variation time of the normal symbol variation game. The winning symbol of the determined normal symbol becomes the fixed stop symbol derived in the normal symbol variation game. On the other hand, if the main control CPU 30a does not win the normal winning lottery, the main control CPU 30a performs a normal deviation process. In the normal deviation process, the main control CPU 30a determines a normal symbol deviation symbol and also determines a normal symbol variation pattern. The decided symbol out of the normal symbol becomes the fixed stop symbol derived in the normal symbol variation game.

  Then, the main control CPU 30a causes the normal symbol display device 25 to execute the normal symbol variation game according to the determination result in the normal hit processing or the normal deviation processing performed based on the lottery result of the normal hit lottery, After a lapse of time, the normal winning symbol or the unusual symbol is displayed in a fixed stop state. In addition, when the normal winning lottery is won, the main control CPU 30a causes the normal winning game to occur after the normal symbol variation game ends. In the normal hit game, the second start port 13 is opened in a predetermined opening pattern, so that the second start port 13 is controlled so as to be allowed to enter the game ball.

  The main control CPU 30a performs processing described below in addition to the processing described above. For example, the main control CPU 30a may specify a demo command (standby state) that can be specified as a control information when a demonstration effect execution condition is satisfied without a special symbol variation game being held. Information). The demo command is transmitted to the sub control CPU 31a at a predetermined timing by a command transmission process performed by the main control CPU 30a. Further, in the processing related to the error, processing such as notification is performed by detecting various errors generated in the pachinko gaming machine 10.

Hereinafter, a process (normal process) performed when the sub control CPU 31a of the sub control board 31 receives the control information related to the game effect described above will be described.
First, processing related to the symbol variation game of the effect symbols will be described.

  When receiving the change start command, the sub control CPU 31a determines a sub change pattern for controlling the display content of the effect display device 11 based on the type of the main change pattern that can be specified from the command. The sub variation pattern can specify the content of the effect of the symbol variation game of the effect symbol.

  Further, when receiving the special symbol command, the sub control CPU 31a, based on the special symbol designated by the special symbol command, identifies information to be derived in the symbol variation game of the effect symbol ([1] to [9] in the embodiment). Determine the combination. When the special symbol jackpot symbol is designated, the sub-control CPU 31a determines the jackpot combination as a combination of effect symbols. In addition, when a special symbol loss symbol is designated, the sub-control CPU 31a determines a combination of loss due to the effect symbol based on the main variation pattern specified from the variation start command. Specifically, the sub-control CPU 31a determines a combination of deviations that can form a reach when a main fluctuation pattern for deviation fluctuation with reach is specified. The combination of outliers that can form a reach is, for example, a combination in which identification information of two specific columns in the identification information of three columns is the same identification information, and identification information of one column excluding the specific two columns Is identification information finally derived by reach production. The sub-control CPU 31a determines a combination of deviations that cannot form a reach when a main fluctuation pattern for deviation fluctuation without reach is specified.

  Further, the sub control CPU 31a determines not only the combination of the sub variation pattern and the effect symbol, but also the type of the notice effect to be performed along with the symbol variation game of the effect symbol. Then, the sub-control CPU 31a, to which the change start command is input, controls the display content of the effect display device 11 so that the symbol change game of the effect symbol is displayed with the effect content according to the above-mentioned determination items. Then, the sub-control CPU 31a controls the display contents of the effect display device 11 so as to end the effect symbol change game and derive the effect symbol combination as the change time specified from the main change pattern elapses. . More specifically, the sub-control CPU 31a ends the symbol variation game of the effect symbol when the variation stop command is input. In this embodiment, the input symbol change game is terminated in response to the input of the change stop command. However, the change time specified from the main change pattern under the control of the sub-control CPU 31a is timed to produce the effect. The symbol variation game may be terminated. That is, the end of the symbol variation game of the effect symbol may be controlled without transmitting the variation stop command from the main control board 30.

Next, processing related to the jackpot game will be described.
When receiving the opening command, the sub-control CPU 31a controls the display content of the effect display device 11 so as to perform the opening effect. Further, when the release command is input, the sub control CPU 31a controls the display content of the effect display device 11 so as to cause an effect accompanying the round game. On the other hand, when the closing command is input, the sub control CPU 31a controls the display content of the effect display device 11 so as to end the effect (round effect) associated with the round game. In addition, when the ending command is input, the sub-control CPU 31a controls the display content of the effect display device 11 so that the ending effect is performed.

Next, processing related to the gaming state will be described.
When receiving the state designation command such as the state 1 designation command, the sub control CPU 31a controls the display content of the effect display device 11 so as to display an image corresponding to the gaming state specified from the command. The image corresponding to the gaming state is a background image displayed on the back of the effect symbol, for example. In addition, when the design of identification information used in the symbol variation game of effect symbols is changed for each gaming state, the image of the identification information is an image corresponding to the gaming state.

  The background image is not limited to a still image, and may be a moving image in which, for example, a part of a cloud moves as time passes if the background image imitates the sky. The background image is behind the image related to the change of the design when the image related to the change of the design (identification information) is the main image (main effect) among the images displayed on the image display unit GH. It can be positioned as an image to be projected. In addition, the background image can be positioned as an image that is displayed in a portion where the effect symbol (identification information) and the notification information to the player (for example, information on the number of start suspensions) are not displayed in the image display unit GH. .

Hereinafter, the operation of the pachinko gaming machine 10 of this embodiment, specifically, the playability of the first special symbol and the second special symbol will be described.
First, the type of jackpot of the first special symbol (shown as “special 1” in the figure) will be described with reference to FIG.

  In this embodiment, the first special symbol ZA and the first special symbol ZB are provided as the first special symbol. When winning the jackpot lottery, the winning probability of the first special symbol ZA by lottery using the jackpot symbol random number is 50%, and the winning probability of the first special symbol ZB is 50%. The winning probabilities of the first special symbols ZA and ZB are defined by the number of values that can be taken by the jackpot symbol random numbers as values to be won for each first special symbol.

  The big hit game when the first special symbol ZA is won is the first big hit game (the game ball easily flows into the specific ball passage 16b). In addition, in the first big hit game when the first special symbol ZA is won, the second big prize opening 15 is opened, and a round game in which a game ball (prize ball) can be substantially obtained during the big hit game. R1 (number of rounds) is defined as the number of rounds. The round game that can substantially obtain the game is a round game in which the opening time of the special winning opening is opened in a long open pattern such as 25 seconds. Note that the round game in which it is not possible to substantially obtain a game is a round game in which the opening time of the big prize opening is opened with a short opening pattern such as 0.4 seconds. The number of winning balls that can be obtained during the jackpot game coincides with the number of round games in which the winning ball can be substantially obtained. In this embodiment, when the first special symbol ZA is won, the number of winning balls (theoretical value) of the first big hit game is D1 (ball). The number of winning balls may be expressed as the total number of game balls (prize balls) paid out by entering the big prize opening, or the number obtained by subtracting the number of shots from the total number of game balls paid out. May be represented.

  In addition, the big hit of the first special symbol ZA makes the gaming state after the end of the big hit game a certain change state by detecting the game ball flowing into the specific ball passage 16b in the specific round game by the specific area sensor TS. . On the other hand, in the big hit of the first special symbol ZA, the game state after the end of the big hit game is changed to an uncertain change state because the specific area sensor TS does not detect the game ball flowing into the specific ball passage 16b in the specific round game. .

  Further, in the big hit of the first special symbol ZA, as described above, when the probability variation state is set, the game state after the big hit game is set to the improved entrance rate at least for the specified number of times (100 times). If the winning lottery is won before reaching the specified number of times, the entrance rate improvement state ends when the specified number of times is reached. Also, the entrance rate improvement state does not win the falling lottery even if the specified number of times is reached, and continues until the falling lottery is won if the probability variation state continues beyond the specified number of times. In this case, the entrance rate improvement state continues by adding α times (variation value), which is the number of times until the falling lottery is won, to 100 times which is a fixed value. In addition, even if the first special symbol ZA is won, if the game ball does not enter the specific ball passage 16b and the end of the big hit game becomes a non-probable change state, the improved entry rate state reaches the specified number of times. End with.

  On the other hand, the big hit game when winning the first special symbol ZB is the second big hit game (the game ball is difficult to flow into the specific ball passage 16b). As in the case of winning the first special symbol ZA, R2 (number of rounds) is prescribed for the second big hit game when the first special symbol ZB is won, and it is acquired. The number of balls (theoretical value) is D1 (sphere).

  In addition, the big hit of the first special symbol ZB makes the gaming state after the end of the big hit game is a certain change state by detecting the game ball flowing into the specific ball passage 16b in the specific round game by the specific area sensor TS. . On the other hand, in the big hit of the first special symbol ZB, the game state after the end of the big hit game is changed to an uncertain change state because the specific area sensor TS does not detect the game ball flowing into the specific ball passage 16b in the specific round game. . Note that the big hit of the first special symbol ZB is always in the non-entrance rate improving state after the end of the big hit game.

Next, the type of jackpot of the second special symbol (shown as “special 2” in the figure) will be described with reference to FIG.
In this embodiment, second special symbols Za, Zb-1, Zb-2, Zc-1, Zc-2, Zd-1, and Zd-2 are provided as the second special symbols. The probability of winning the above-mentioned second special symbol in the lottery using the big-hit symbol random number when winning the big-hit lottery is as follows.

  That is, the winning probability of the second special symbol Za is 50%, the winning probability of the second special symbol Zb-1 is 5%, the winning probability of the second special symbol Zb-2 is 1%, and the second special symbol Zc-1 The winning probability is 9%, the winning probability of the second special symbol Zc-2 is 4%, the winning probability of the second special symbol Zd-1 is 13%, and the winning probability of the second special symbol Zd-2 is 18%. Each second special symbol is assigned a predetermined number of numerical values that can be taken by the jackpot symbol random number so as to have the above-described winning probability.

  The big hit game when winning the second special symbol Za is the first big hit game (the game ball easily flows into the specific ball passage 16b). In addition, in the first big hit game of the second special symbol Za, the number of round games (round) that can substantially obtain a ball (prize ball) during the big hit game by opening the second big prize opening 15 R2 (times) is defined as the number). In this embodiment, when the second special symbol Za is won, the number of winning balls (theoretical value) of the first big hit game is D2 (ball).

  The big hit game when winning the second special symbol Zb-1 is the first big hit game, and the big hit game when winning the second special symbol Zb-2 is the second big hit game (the game to the specific ball passage 16b). Sphere is difficult to flow in). In addition, for each jackpot game when the second special symbol Zb-1, Zb-2 is won, by opening the second jackpot 15 to substantially get a ball (prize ball) during the jackpot game R3 (number of times) is defined as the number of round games that can be played (number of rounds). In this embodiment, when the second special symbol Zb-1 or Zb-2 is won, the number of winning balls (theoretical value) for each big hit game is D3 (ball).

  The jackpot game when winning the second special symbol Zc-1 is the first jackpot game, and the jackpot game when winning the second special symbol Zc-2 is the second jackpot game. In addition, for each big hit game when the second special symbol Zc-1, Zc-2 is won, by opening the second big prize opening 15 to substantially get a ball (prize ball) during the big hit game R4 (times) is defined as the number of round games that can be played (number of rounds). In this embodiment, when the second special symbol Zc-1 or Zc-2 is won, the number of winning balls (theoretical value) for each big hit game is D4 (ball).

  The big hit game when winning the second special symbol Zd-1 is the first big hit game, and the big hit game when winning the second special symbol Zd-2 is the second big hit game. In addition, for each big hit game when the second special symbol Zd-1, Zd-2 is won, the second big prize opening 15 is opened to substantially obtain a ball (prize ball) during the big hit game. R5 (times) is defined as the number of round games that can be played (number of rounds). In this embodiment, when the second special symbol Zd-1, Zd-2 is won, the number of winning balls (theoretical value) for each big hit game is D5 (ball).

  In addition, the big special hits of the second special symbols Za, Zb-1, Zb-2, Zc-1, Zc-2, Zd-1, Zd-2 are game balls that have flowed into the specific ball passage 16b in a specific round game. As a result of detection by the specific area sensor TS, the gaming state after the end of the big hit game is changed to a probability change state. On the other hand, the game balls that flow into the specific ball passage 16b in a specific round game are the big hits of the second special symbols Za, Zb-1, Zb-2, Zc-1, Zc-2, Zd-1, and Zd-2. By not being detected by the specific area sensor TS, the gaming state after the end of the big hit game is changed to a non-probable change state. In the following, for convenience of explanation, the second special symbol Za, Zb-1, Zc-1, Zd- that the jackpot game is the first jackpot game and becomes probabilistic with an extremely high probability after the jackpot game ends. One big hit may be indicated as “probable big hit”. On the other hand, in the following, for convenience of explanation, the second special symbol Zb-2, Zc-2, Zd that the jackpot game is the second jackpot game and becomes indeterminate with a very high probability after the jackpot game ends. -2 jackpot may be shown as "non-probable big hit".

  In addition, in the big hit of the second special symbols Za, Zb-1, Zb-2, Zc-1, Zc-2, Zd-1, Zd-2, as described above, if the probability variation state is set, after the big hit game ends. The game state is set to an improved entrance rate at least for a specified number of times (100 times). If the winning lottery is won before reaching the specified number of times, the entrance rate improvement state ends when the specified number of times is reached. Also, the entrance rate improvement state does not win the falling lottery even if the specified number of times is reached, and continues until the falling lottery is won if the probability variation state continues beyond the specified number of times. Even if the second special symbol Za, Zb-1, Zb-2, Zc-1, Zc-2, Zd-1, Zd-2 is won, the game ball does not enter the specific ball passage 16b. When the big hit game is in a non-probable change state, the ball entering rate improvement state ends when the specified number of times is reached.

  As described above, in the pachinko gaming machine 10 of this embodiment, when a game ball is detected by the specific area sensor TS in a specific round game during the big hit game, the gaming state becomes a probabilistic state immediately after the end of the big hit game. On the other hand, in the pachinko gaming machine 10 according to this embodiment, when a game ball is not detected by the specific area sensor TS in a specific round game during the big hit game, the gaming state becomes an uncertain change state immediately after the big hit game ends.

  Further, as shown in FIG. 7, the pachinko gaming machine 10 of this embodiment has a plurality of types of jackpots that can cause a difference in the number of balls in the jackpot game for the jackpot of the second special symbol. Specifically, when the number of balls is roughly divided, the second special symbol Za, the second special symbol Zb-1, Zb-2 (collectively indicated as “Zb” in the figure), the second 4 of special symbols Zc-1, Zc-2 (collectively indicated as “Zc” in the figure) and second special symbols Zd-1, Zd-2 (collectively indicated as “Zd” in the figure) Can be classified. The number of balls to be played increases in the order of second special symbol Zd (D5) → second special symbol Zc (D4) → second special symbol Zb (D3) → second special symbol Za (D2).

  In the pachinko gaming machine 10 of this embodiment, for the big hit of the second special symbol, the big hit distribution is set as shown in FIG. Expected value to win is different. More specifically, as shown in FIG. 7, the expected value is the second special symbol Zd (X4) → second special symbol Zc (X3) → second special symbol Zb (X2) → second special symbol Za ( It becomes higher in the order of X1). In other words, the order of the expected value is equal to the order of the number of balls, and the winning value for the next jackpot after the end of the jackpot game is higher as the jackpot with the larger number of balls is won. Thereby, the pachinko gaming machine 10 of this embodiment has a correlation between the number of balls and the expected value as described above.

  The expected value for winning the next big hit mentioned above is the expected value for winning the big hit when the game state is either a probability change state and an improved entry rate state, or a non-probable change state and an entry rate improvement state. It is. In other words, the expected value for winning the jackpot in this embodiment is also the expected value for winning the jackpot during the improved entrance rate. The expected value for each type of jackpot (classification of the number of balls) can be defined based on the elements described below.

  Specifically, since the expected value for the second special symbol Za is a distribution only for the probabilistic big hit, the winning probability of the big hit lottery in the probable state and the winning probability of the big win lottery in the non-probable state It can be defined based on the winning probability of the falling lottery and the condition for giving the improved entrance rate.

  In addition, since the expected value for the second special symbol Zb to Zd is the distribution of the probable big hit and the non-probable big hit, the winning probability of the big win lottery in the probable state and the winning probability of the big win lottery in the non-probable state In addition, it can be defined on the basis of the winning probability of the falling lottery, the condition for giving the improved entrance rate, and the ratio of the probability variation big hit and the non-probability big hit.

  In other words, the second special symbol Za with only a probable big hit is guaranteed to improve the entrance rate for the specified number of times (100 times), and even if the specified number of times is exceeded, the entrance rate is improved until the winning lottery is won. Since this continues, there is a high probability of winning a big hit while the rate of entry is improving. On the other hand, the second special symbol Zb to Zd having a probabilistic big hit and a non-probable big hit has the same conditions as the second special symbol Za and the condition for improving the entrance rate, but has a non-probable big hit to enter the ball. The possibility of winning a big hit during the rate improvement state is lower than that of the second special symbol Za. The expected values of the second special symbols Zb to Zd vary according to the ratio of the non-probable variation big hit because the conditions for giving the improved entrance ratio are the same. The chance of winning a big hit during the state is low. Note that the expected value is set such that the height difference is about 50% to 90%, for example. And in the pachinko gaming machine 10 of this embodiment, there is a relationship in which some of the number of balls and the expected value match. Specifically, the expected value increases as the number of appearing balls increases, and conversely, the expected value decreases as the number of appearing balls decreases.

The pachinko gaming machine 10 of this embodiment can provide the gaming characteristics described below by providing a correlation between the number of balls played as described above and the expected value to be won in the next jackpot.
FIG. 8 shows types of effect modes and transition modes of effect modes.

  The pachinko gaming machine 10 of this embodiment has a normal mode and a continuation mode as production modes. The normal mode is a second performance mode that stays when the gaming state is in the non-entry rate improvement state, and the continuous mode is the probability change state and the entrance rate improvement state, or the non-probability change state and the entrance rate improvement. This is the first effect mode in which the user stays when in any state. The continuation mode can be positioned as an effect mode in which the entrance rate is improved with respect to the normal mode in which the entrance rate is not improved. In this embodiment, the control of the effect mode is that the sub-control CPU 31a that has received the state designation command controls an image such as a background image displayed on the effect display device 11, and the sub-control CPU 31a is in the effect mode. It functions as mode control means for controlling transition. In the normal mode and the continuation mode, the images displayed on the effect display device 11 are different, and are visually distinguishable.

  In the pachinko gaming machine 10 of this embodiment, the winning probability of the normal lottery is set low (close to 0%) during the non-entrance rate improvement state (during the normal mode stay), so that the second start port It is difficult to take an allowable state in which 13 is allowed to enter a game ball. For this reason, during the non-entrance rate improvement state, the game performance is such that the first start opening 12 enters the ball and the start condition of the first special symbol is obtained.

  And, when the first special symbol ZA is won during the non-entrance rate improvement state, either after the jackpot game is finished, the probability change state and the entrance rate improvement state, or the non-probability change state and the entrance rate improvement state By entering the state, the effect mode after the end of the big hit game becomes the continuous mode. At this time, the sub-control CPU 31a enters the continuous mode by receiving the state 2 designation command or the state 3 designation command. On the other hand, if the first special symbol ZB is won during the non-entrance rate improvement state, either the probability change state and the non-entry rate improvement state or the non-probability change state and the non-entry rate improvement state after the end of the big hit game In such a state, the effect mode after the end of the big hit game becomes the normal mode. At this time, the sub control CPU 31a enters the normal mode by receiving the state 1 designation command or the state 4 designation command.

  In addition, the pachinko gaming machine 10 according to this embodiment has a high starting probability (close to 100%) during a state where the entrance rate is improved (during the stay in the continuous mode), so that the second start The mouth 13 can be allowed to enter the game ball. For this reason, in a state where the entrance rate is improved, a game property is obtained in which the start condition of the second special symbol is obtained by entering the second start port 13.

  While winning the winning rate, if you win the jackpot lottery, you win any of the jackpots shown in Fig. 6, and after the jackpot game ends, the probability change state and the entrance rate improvement state, or the non-probability change state and the entrance rate improvement By entering any one of the states, the effect mode after the end of the big hit game becomes the continuation mode. On the other hand, when the end condition of the entrance rate improvement state is satisfied during the entrance rate improvement state, the effect mode is the normal mode. In this embodiment, the entrance rate improvement state is established when the specified number of times is reached when in the non-probable change state, and is established by winning the falling lottery when the probability change state continues beyond the specified number of times. Then, the sub control CPU 31a enters the normal mode by receiving the end command.

  In the pachinko gaming machine 10 of this embodiment, after winning the jackpot lottery of the first special symbol and shifting to the continuation mode, the presentation mode is determined by repeatedly winning the jackpot lottery of the second special symbol in the continuation mode after the transition. Continue in continuation mode. As shown in FIG. 6, for the big hit in the continuous mode, there is a correlation between the number of balls and the expected value to win the next big hit. For this reason, during the continuation mode, when the big hit lottery is won and the big hit game is awarded, the big hit lottery is won again in the continuous mode, that is, in the improved entrance rate, based on the number of balls in the big hit game. While being aware of the expected value, it will be a game where you can get the expectation to win the next big hit. And the expected value fluctuates depending on the number of balls in play, which also changes the expectation of winning the next big hit.

FIGS. 9A and 9B show examples of special effects performed during the continuation mode.
In this embodiment, the sub-control CPU 31a displays a message image G1 as a special effect on the image display unit GH during the continuation mode. The message image G1 is a message that “the more winnings are earned, the more chances are !!”, which is configured to notify that there is a correlation between the number of appearing balls and the expected value to win the next jackpot. Yes.

  Note that the message image G1 may be fixedly displayed in a predetermined area of the image display unit GH, or may be displayed by moving to a predetermined area of the image display unit GH, such as a telop display. It may be. Further, the message image G1 may be displayed on the image display unit GH at all times during the continuous mode. For example, the message image G1 is displayed on the image display unit GH every predetermined number of games or every predetermined time. There may be. Further, the message image G1 may be displayed when an execution availability lottery is performed when a predetermined opportunity arrives, such as when a symbol variation game is started, and the execution availability lottery is won.

  Further, as shown in FIG. 9B, the sub-control CPU 31a displays the notice image G2 as the notice effect for notifying the big hit expectation degree of the symbol variation game during the execution of the symbol variation game of the effect symbol. Can be displayed. A plurality of types of notice effects are provided, and a big hit expectation is set for these notice effects. Specifically, there is a notice effect with a high jackpot expectation level that is likely to appear when a big hit occurs, and a notice effect with a low expectation level that is likely to appear when lost. Then, unlike the notice effect, the message image G1 as the special effect does not notify the big hit expectation degree related to the symbol variation game of the effect symbol executed at the time of appearance. In other words, the notice effect is determined based on the lottery result of the big hit lottery and the type to be executed is determined, but the special effect (message image G1) is executed without considering the lottery result of the big hit lottery. It is.

Therefore, according to this embodiment, the following effects can be obtained.
(1) Expected to win the next jackpot during the continuation mode based on the number of balls played during the jackpot game by having a correlation between the number of balls played and the expected value to win the next jackpot during the continuation mode Change in feeling. Therefore, the interest of the pachinko gaming machine 10 having the probability variation function can be improved.

  (2) In addition, the correlation between the number of appearances and the expected value is a relationship in which the expected value increases as the number of appearances increases. Can be achieved.

  (3) When the hit rate is improved after the end of the jackpot game, the mode is changed to the continuous mode after the end of the jackpot game regardless of the type of the jackpot. For this reason, it is possible to entertain the game in the continuous mode while making the player aware of the relationship between the number of appearances and the expected value as compared to the case where the effect mode is provided for each type of jackpot.

  (4) Further, by shifting to the same continuous mode, even if it is a specification that can be in a non-probability change state after the end of the big hit game like the pachinko gaming machine 10 of the embodiment, it is in a non-probability change state. This can be made difficult for the player to see. In other words, it is possible to add an element to conceal whether the state is probabilistic or non-probable, and entertain the game in the continuous mode while making the player aware of the relationship between the number of balls and the expected value. be able to.

  (5) Gathering the player's attention to whether or not a promiscuous state can be obtained during a big hit game (specific round game) by making the specification that can be in a non-probable change state after the end of the big hit game Can do. In other words, since the expected value in the continuation mode fluctuates because there is a case that can be in a non-probable change state immediately after the end of the big hit game, it gives a strong throbbing feeling to whether a probable change state can be obtained during the big hit game , Can improve the interest.

  (6) Moreover, since the pachinko gaming machine 10 of this embodiment is a fall lottery machine, it is up to the player's luck how long the probability variation state continues even if the probability variation state is obtained. For this reason, while changing the expectation level depending on the number of balls, it is possible to give a strong throbbing feeling due to the probable state of not knowing how long it will continue, and to improve the interest. In other words, even if you can get a lot of balls, if you win the falling lottery at an early stage, the chance of getting the next big hit is low, so while continuing mode continues or next big hit Until you win, you can't get a sense of security and you can improve your interest.

  (7) In addition, the falling lottery machine will continue to be probable until winning the falling lottery, so even if you win a big hit with a small number of balls and the expected value is low, There is still a chance to win. For this reason, the expectation for the big hit can be obtained until the continuation mode is completed, and the interest can be improved.

  (8) Even if the falling lottery is won by the specified number of times until the specified number of times is reached, it continues until the specified number of times, and even if the specified number of times is reached, if it is in a probable state, it continues until the falling lottery is won. It is a specification. Therefore, the continuation mode is performed in a state advantageous to the player, at least in a state where the entrance rate is improved, and the next big hit can be aimed at without significantly reducing the player's possession. In particular, even in the case of a specification that may cause a difference in the number of balls as in the pachinko gaming machine 10 of this embodiment, during the continuous mode, an advantage and disadvantage is generated in terms of maintaining the player's possession. Without being able to digest the continuation mode with confidence.

  (9) Since the special effect (message image G1) is executed and the player is informed that there is a correlation between the number of balls and the expected value, the player can be made to understand the game characteristics. Then, by letting the player understand the correlation between the number of balls and the expected value, it is possible to sufficiently enjoy the game during the big hit game or the continuous mode. In addition, unlike the notice effect, the special effect is an effect that does not inform the jackpot expectation. For this reason, the role of the notice effect can be clearly drawn, and the existence value of the notice effect can be prevented from being impaired.

(Second Embodiment)
Hereinafter, a second embodiment embodied in a pachinko gaming machine will be described with reference to FIGS. In the embodiments described below, the same configurations and the same control contents as those of the embodiments already described are denoted by the same reference numerals, and redundant descriptions thereof are omitted or simplified.

  In this embodiment, the opening pattern of the first big winning opening 14 in the specific round game of the first big win game and the opening pattern of the first big winning opening 14 in the specific round game of the second big hit game are the same. Open pattern. Specifically, in any case, the opening pattern of the first big winning opening 14 is a long opening pattern. The first big hit game is a “probability big hit” defined for convenience of explanation in the first embodiment, and the second big hit game is a similarly defined “non-probable big hit”.

  And in this embodiment, the mode (timing) which permits inflow of the game ball into the specific ball passage 16b is varied depending on the type of jackpot of the second special symbol. Specifically, by changing the operation pattern of the sorting member 17 in a specific round game, the mode (timing) of allowing the flow of the game ball into the specific ball passage 16b is changed.

FIG. 10 shows an operation pattern of the specific round game and the sorting member 17 determined as the type of jackpot of the second special symbol.
For the big hit of the second special symbol Za, the specific round game is a round game with the number of rounds “Ra”, and the operation pattern of the distribution member 17 is defined as the operation pattern C1. In the big hit of the second special symbol Zb (Zb-1, Zb-2), the specific round game is a round game of the number of rounds “Rb”, and the operation pattern of the sorting member 17 is defined as the operation pattern C2. For the big hit of the second special symbol Zc (Zc-1, Zc-2), the specific round game is a round game with the number of rounds “Rc”, and the operation pattern of the sorting member 17 is defined as the operation pattern C3. For the big hit of the second special symbol Zd (Zd-1, Zd-2), the specific round game is a round game with the number of rounds “Rd”, and the operation pattern of the sorting member 17 is defined as the operation pattern C4.

  The number of rounds of a specific round game is determined such that, for example, “Ra” rounds are “first round game”, and “Rb” rounds are “second round game”. The number of rounds of a specific round game determined for each jackpot may be a different number of rounds of a specific round game for all jackpots, or the number of rounds of a specific round game for some jackpots It may be the same number of times.

  In addition, in the operation pattern, as a mode (timing) in which the sorting member 17 is operated so as to allow the inflow of the game ball into the specific ball passage 16b, the ball enters the first big winning opening 14 during the specific round game. The number of entered game balls is determined. In this embodiment, the movement pattern C1 allows the distribution member 17 to flow into the specific ball passage 16b on the condition that “first ball” and “third ball” are counted as the number of balls entered. It is stipulated to operate as follows. Further, in the operation pattern C2, the distribution member 17 is provided on the condition that “2nd ball” and “4th ball” are counted as the number of balls entered in the case of the first big hit game (second special symbol Zb-1). It is determined that the game ball is allowed to be allowed to flow into the specific ball passage 16b. On the other hand, in the operation pattern C2, in the second big hit game (second special symbol Zb-2), the distribution member 17 is moved to the specific ball passage 16b on the condition that “second ball” is counted as the number of balls entered. It is stipulated that the game ball is allowed to move in. It should be noted that the number of balls entered in the action pattern determined for each jackpot may be different for all jackpots, may be the same for some jackpots, or may be for some jackpots. The number of balls may be the same as that of other big hits.

  In addition, each of the operation patterns C1 to C4 of this embodiment is determined so that the distribution member 17 is operated twice for the first big hit game, and the distribution member 17 is operated once for the second big hit game. It is stipulated to let you. When the sorting member 17 is operated twice, the first operation time is the first time (short time), and the second operation time is the second time (long time) longer than the first time. . On the other hand, when the sorting member 17 is operated once, the first operation time is the first time (short time).

  The number of balls entered into the first big prize opening 14 and the second big prize opening 15 during the big hit game is counted by the main control CPU 30a that receives the detection signals from the count sensors CS1 and CS2. That is, the main control CPU 30a counts the number of balls entered during a specific round game based on the detection result of the count sensor CS1, and during a round game other than the specific round game based on the detection result of the count sensor CS2. Functions as a counting means for counting the number of incoming balls.

  Further, the main control CPU 30a, during the jackpot game won for any of the second special symbols Za to Zd, the distribution member 17 of the sorting member 17 according to the operation pattern in a specific round game determined for the type of the jackpot won Control the behavior. More specifically, the main control CPU 30a counts a predetermined number of balls determined in the operation pattern during a specific round game to allow the game balls to enter the specific ball path 16b. The operation of the minute member 17 is controlled.

  FIG. 11 shows the control contents of the sorting member 17 executed by the main control CPU 30a when the second special symbol Za and the second special symbol Zb (Zb-1, Zb-2) are won. In the count column shown in the figure, “1C” to “8C” indicate the number of balls, “1C” indicates the number of balls, “2C” indicates the number of balls, and so on. In addition, “short” and “long” shown in the figure represent the operation time for operating the sorting member 17 to allow the game ball to enter the specific ball passage 16b, and “short” is the first time. “Long” indicates a long time as the second time. Note that the sorting member 17 is always in the second position (the position of the two-dot chain line shown in FIG. 4) that blocks the entrance of the specific ball passage 16b.

  When the second special symbol Za is won, the main control CPU 30a counts the first ball (corresponding to a predetermined ball number) as the number of balls entered according to the operation pattern C1, and the number of balls entered When the third ball (corresponding to a predetermined number of balls) is counted, the sorting member 17 is moved to the first position. The first position is a position (a solid line position shown in FIG. 4) that does not block the entrance of the specific ball passage 16b. At this time, the main control CPU 30a moves the sorting member 17 to the first position when the first ball is counted, and moves the sorting member 17 to the first position for the second time when counting the third ball. Move to one position. When the sorting member 17 is moved to the first position, the inflow of game balls into the specific ball passage 16b is allowed.

  The second time is set as a sufficient time from when the game ball that has entered the first grand prize opening 14 is detected by the count sensor CS1 to the entrance of the specific ball passage 16b. On the other hand, the first time is set so that the possibility that a game ball that has entered the first grand prize winning port 14 is detected by the count sensor CS1 and then flows into the specific ball passage 16b is extremely low. For this reason, the game ball that has entered the first grand prize opening 14 is very likely to flow into the specific ball passage 16b in the third ball rather than the first ball.

  In addition, when the second special symbol Zb-1 is won, the main control CPU 30a counts the second ball (corresponding to a predetermined ball number) according to the operation pattern C2, When the fourth ball (corresponding to a predetermined number of balls) is counted as the number of balls entered, the sorting member 17 is moved to the first position. When the second special symbol Zb-2 is won, the main control CPU 30a counts the second ball (corresponding to a predetermined ball number) according to the operation pattern C2, The sorting member 17 is moved to the first position. The time for operating the first position is the same as the operation pattern C1.

  As described above, in the case of the second special symbol Zb, when the second special symbol Zb-1 which is the first big hit game is won, the game ball which has entered the first big winning opening 14 enters the specific ball passage 16b. The possibility of inflow is very high. On the other hand, when the second special symbol Zb-2 that is the second big hit game is won, the possibility that the game ball that has entered the first big winning opening 14 flows into the specific ball passage 16b is extremely low. As a result, the second special symbol Zb-1 is likely to be in a probable state after the end of the big hit game, and the second special symbol Zb-2 is likely to be in a non-probable state after the end of the big hit game.

  Note that the game balls that can be a predetermined specified number such as the first ball and the third ball that are defined in the operation pattern are game balls that can act as a trigger for moving the sorting member 17 to the first position, and the game balls themselves Whether or not actually flows into the specific ball passage 16 b depends on the structure of the first big winning opening 14 and the movement of the game ball in the ball passage 16. In other words, the sorting member 17 operates by entering a predetermined specified number of game balls, but whether or not the probability variation state can be obtained is detected by the specific area sensor TS when the game ball flowing into the specific ball passage 16b is detected. The identity of the game ball detected by the specific area sensor TS and the game ball triggered by the operation of the sorting member 17 is not questioned.

  In addition, there are the operation pattern C3 of the second special symbol Zc and the operation pattern C4 of the second special symbol Zd. The control of the main control CPU 30a based on these operation patterns is the operation pattern C2 of the second special symbol Zb described above. It is the same. In other words, the main control CPU 30a moves the sorting member 17 when the predetermined number of entered balls is counted according to the operation patterns C3 and C4 and whether the game is a first big hit game or a second big hit game. Operate to the first position. In this embodiment, the main control CPU 30a functions as an operation control unit that changes the operation of the sorting member 17 in accordance with the number of balls entered by the count sensor CS1. Note that the change in operation includes a change for each type of jackpot and a change in the same jackpot (one-time operation or two-time operation).

  In the pachinko gaming machine 10 of this embodiment, the opening pattern of the first big winning opening 14 is made the same in a specific round game, and the operation pattern of the distribution member 17 is made different between the first big hit game and the second big hit game. Yes. For this reason, it is more difficult to determine which jackpot is won in the jackpot that can obtain the same number of balls, such as the second special symbol Zb-1 and the second special symbol Zb-2. That is, it is difficult to determine whether or not the game ball that has entered the first grand prize opening 14 flows into the specific ball passage 16b and is detected by the specific area sensor TS, in other words, after the end of the big hit game. It is difficult to assume whether the state is a probability variation state or a non-probability variation state. Further, in this embodiment, if the specific area sensor TS is configured not to notify that a game ball has been detected, the above assumption becomes even more difficult.

  In the pachinko gaming machine 10 of this embodiment, as described above, the opening pattern of the first big winning opening 14 is the same in the first big hit game and the second big hit game in a specific round game. For this reason, when this embodiment is adopted in the first embodiment, the number of balls shown in FIGS. 5 and 6 is the long open pattern regardless of whether the first big prize opening 14 or the second big prize opening 15 is used. It can be defined by the number of balls that can be obtained when it is released.

Therefore, according to this embodiment, in addition to the effects (1) to (9) of the first embodiment, the following effects can be obtained.
(10) By changing the mode (timing) of allowing the inflow of game balls into the specific ball passage 16b depending on the type of jackpot of the second special symbol, whether the game state (probability change state) after the end of the jackpot game, It is difficult to assume whether or not the state is indeterminate. In other words, in the V probability variation machine, an element for concealing whether the state is a certain variation state or a non-probability variation state can be added. Therefore, the interest of the pachinko gaming machine 10 having the probability variation function can be improved.

  (11) Further, by not notifying that the game ball has been detected by the specific area sensor TS, it is further difficult to assume a game state (whether it is a probable change state or a non-probability change state) after the big hit game is ended. Can improve the interest.

  (12) In a specific round game, a situation in which a game ball is likely to flow into the specific ball passage 16b and a situation in which it is difficult to flow in are created by the operation of the sorting member 17. For this reason, even in a specific round game, a prize ball can be obtained by entering the first big prize opening 14.

In addition, you may change each said embodiment as follows.
-It may be embodied in a pachinko gaming machine with a single big prize opening. This single big prize opening is the structure provided with the distribution member 17 like the 1st big prize opening 14 demonstrated in embodiment. In the first embodiment, the opening pattern of a specific round game is made different depending on whether the game is a first jackpot game or a second jackpot game. In the second embodiment, the operation pattern of the sorting member 17 in a specific round game is made different depending on the type of jackpot, the first jackpot game, or the second jackpot game. A pachinko machine equipped with a single big winning opening counts the number of balls entered during a round game based on the detection results of the count sensor CS1 (first detection means) and the first detection means described in the embodiment. A main control CPU 30a (counting means) and a specific area sensor TS (second detecting means) for detecting a game ball flowing into the specific ball passage 16b are provided. In the case of providing a single big winning opening, the specific ball passage 16b is allowed to flow in game balls in a specific round game. The entrance of the specific ball passage 16b is blocked by the sorting member 17 being in the second position so as not to allow the inflow of game balls in round games other than the specific round game.

  -When transitioning to the continuation mode after the end of the jackpot game, a notification means for notifying the current game state may be provided when the number of executions of the symbol variable game after the end of the jackpot game reaches a specified number. As a specific example in the case of application to the embodiment, it is not notified whether the state is the probability variation state or the non-probability variation state until the specified number of times (100 times) is reached. And even if the predetermined number of times is reached, if the falling lottery is not won and the probability variation state is continued (that is, if the entrance rate improvement state is continued), for example, the effect display device 11 (image display unit GH). ) May be used as a notification means, and a message image “Probability change continuation!” May be displayed on the effect display device 11 to notify that it is in a probability change state. According to this configuration, it is possible to cause the player to recognize that the probability variation state continues by notification from the notification means.

  -Although the said another example alert | reported that it is a probability variation state, it is a non-probability variation state (that is, the entrance rate improvement state is complete | finished), for example, the effect display apparatus 11 (image display part GH) alert | reporting means May be notified. According to this configuration, the game state can be recognized by the player by notification from the notification means.

  In addition, the notification in each of the above examples may be shifted to a special production mode if, for example, the probability change state is reached when the specified number of times is reached. In addition, when the remaining number of times (or the number of elapsed times) in the entrance rate improvement state is notified during the continuous mode, the notification may be performed by displaying the number of times. For example, when the remaining number of times is notified, the display mode of “0” may be changed after the number of times reaches “0” (color change, blinking display from lighting display). In addition, for example, when the number of elapsed times is informed, the display of the number of times may be continued even if it exceeds “100”, or it is changed to a display that can specify that it exceeds 100 times, such as “100 + α”. May be.

  Further, as the notification by the above-described notification means, a message may be “definite change confirmation if the entrance rate improvement state continues after the specified number of times (100 times)!”. This message may be applied as a notification when the number of times of execution of the symbol variation game after the end of the big hit game has reached the specified number of times, or a notification explaining the game nature to the player before the predetermined number of times is reached. As well as

  In addition, the notification in each of the above examples may be performed by other means (for example, a light emitter such as a lamp, a speaker, or a movable body) instead of the effect display device 11. In addition, when a plurality of liquid crystal display devices (for example, a main liquid crystal and a sub liquid crystal) are provided, any one of the liquid crystal display devices may be used as notification means to perform notification. The notification may be executed by combining a plurality of means.

  The means for executing the special effects shown in FIGS. 9A and 9B may be other means (for example, a light emitter such as a lamp, a speaker, and a movable body) instead of the effect display device 11. When a plurality of liquid crystal display devices (for example, a main liquid crystal and a sub liquid crystal) are provided, a special effect may be executed on any of the liquid crystal display devices. The special effect may be executed by combining a plurality of means.

  -The message content of the special effect may be changed. For example, it may be a content that directly represents the correlation between the number of balls to be played and the expected value, such as “the larger the number of earned balls, the higher the expected value of the jackpot!”. In addition, for example, the message content (having a correlation) is the same, but there are multiple types of special effects (message contents) with different expression methods, and when special effects are executed, The type may be selected by lottery, or the type of special effect may be selected according to a predetermined order. When multiple types of special effects are provided, all the special effects may be effects executed by a specific means (for example, the image display unit GH), or some special effects or all special effects are different. An effect executed by means may be used.

  -The special effect may be executed during a big hit game. In this case, the special effect may be continuously executed even in the symbol variation game after the end of the big hit game, or may be executed only during the big hit game.

  -In the distribution of the 2nd special symbol shown in FIG. 6, you may make it transfer to different production modes for every kind of jackpot (4 classification demonstrated in embodiment). The effect mode in this case is the same as the gaming state in which the stay is possible, but the background image is changed for each effect mode to distinguish the appearance. Such an effect mode for each type of jackpot also corresponds to a special effect. In addition, the production mode in this case corresponds to the continuation mode described in the embodiment, and stays when the state is either the probability variation state and the entrance rate improvement state, or the non-probability change state and the entrance rate improvement state. This is the first production mode.

In the first embodiment, the specific round game may be the same number of round games or a different number of round games.
In the first embodiment, the operation pattern of the sorting member 17 in a specific round game may be different depending on whether the game is a first big hit game or a second big hit game.

  -In the distribution of the second special symbol shown in FIG. 6, the jackpot that can be the second jackpot game such as the second special symbol Zb-2, Zc-2, Zd-2 is not set, only the jackpot that can be the first jackpot game May be set. In this case, the probable state is given at a rate of almost 100% for the big hit of the second special symbol. Then, as in the first embodiment, in order to provide a correlation between the number of balls to be played and the expected value for the next jackpot, the prescribed number of times of entry rate improvement may be made different for each jackpot type.

  In the distribution of the second special symbol shown in FIG. 6, for the second special symbol Za, for example, as in the case of the second special symbol Zb, the big hit that becomes the first big hit game (after the big hit game is over, the probability change state may be established) A big hit that has a high probability) and a big hit that becomes the second big hit game (a big hit that is likely to become a non-probability state after the big hit game is finished) may be set. Even in this case, as described in the first embodiment, it is possible to create a correlation between the number of outgoing balls and an expected value.

  In the distribution of the first special symbol shown in FIG. 6, when the first special symbol ZB is won, an improved entry rate state (for example, 100 times) may be given. And in this case, you may make it transfer to another production mode different from normal mode or continuation mode, and to make it transfer to normal mode when the completion | finish conditions of the entrance rate improvement state are satisfied.

  The pachinko gaming machine 10 according to the embodiment is a V-probability changing machine and a falling lottery machine, but is equipped with a probability changing function that continues the probability changing state until a predetermined number of symbol changing games are executed after the big hit game is finished. In the gaming machine, as in the first embodiment, there may be a correlation between the number of balls played and the expected value for the next jackpot. This type of pachinko gaming machine is also called an ST machine (number cutting machine). In this case, it is possible to provide a correlation between the number of balls to be played and the expected value for the next jackpot by changing the prescribed number of times of the improved entrance rate for each jackpot type. Note that the ST machine can end the probability variation state when an end condition different from the condition for winning the big hit lottery is satisfied. In addition, the ST machine may have a specification that is surely changed after the end of the big hit game, or a specification that is equipped with a non-probable big hit and is in a probable state or a non-probable state after the end of the big hit game. Also good.

  -The pachinko gaming machine 10 of the embodiment is a V-like change machine and a falling lottery machine, but the number of times that the probability change state has been continued (the number of consecutive big wins with the probability change state after the end of the big hit game) has reached a predetermined number of times. In the pachinko gaming machine equipped with the probability variation function for ending the probability variation state, the number of balls to be played and the expected value for the next jackpot may be correlated as in the first embodiment. This type of pachinko machine is also called a limiter machine. In the limiter machine, for example, when the number of times of continuation is “7”, the seventh big hit becomes a big hit that becomes an uncertain change state after the end of the big hit game. In this case, there is a correlation between the number of balls played and the expected value of the next jackpot by varying the number of specified hits in the improved entrance rate for each jackpot type for the jackpot that will be in a probabilistic state after the end of the jackpot game. Can be made. With this configuration, in the limiter machine, the game performance can be imparted by the correlation between the number of balls played and the expected value after the jackpot game is over until the last big hit, that is, the probability variation state continues. . It should be noted that the limiter machine can end the probability variation state when an end condition different from the condition for winning the big hit lottery is satisfied.

  The second embodiment may be applied to a V-variable machine that does not have a correlation between the number of balls and the expected value of the next jackpot as in the first embodiment. Specifically, the jackpot corresponding to the first special symbol ZA in FIG. 5 and the jackpot corresponding to the first special symbol ZB are mounted, and the operation pattern of the distribution member 17 is made different so that any jackpot is achieved. It may be difficult to tell if you have won. This another example is another example referring to the presence or absence of a correlation, and may include a plurality of types of jackpots that may cause a difference in the number of balls as a jackpot distribution. And according to this example, the element which conceals whether it is a probability change state or a non-probability change state can be added after completion | finish of a big hit game similarly to 2nd Embodiment. For this reason, as the effect mode, the first effect mode where the game state stays in either the probability change state or the non-probability change state, and the game state stays when the game state is neither the probability change state nor the entrance rate improvement state. The second production mode is provided, and the first production mode can be handled as the concealment mode by shifting to the first production mode after the end of the big hit game. In this example, since no correlation is given, after the jackpot game is over, the state may be in either the entry rate improvement state or the non-entry rate improvement state. For this reason, the 1st production mode is good also as a production mode in the entrance rate improvement state, and good also as a production mode in the non-entrance rate improvement state.

  -In the second embodiment, when the aspect (timing) that allows the inflow of the game ball into the specific ball passage 16b is different depending on the type of jackpot of the second special symbol, the specific round game is assumed to be the same in all jackpots. Only the operation pattern (predetermined number of balls) may be varied.

-You may arbitrarily change the winning probability of the jackpot lottery (in the probability variation state, in the non-probability variation state) and the winning probability of the falling lottery.
The V probability changing machine may be a specification that invalidates the detection when the specific area sensor TS detects a game ball in the second big hit game. In other words, the detection at the time of the second big hit game may be treated as fraud or error and invalidated (no probability variation state is given).

  -While the winning probability of the normal lottery in the non-entry rate improving state is set to zero (0%), the winning probability of the normal lottery in the improved entering rate may be set to 100%. In addition, the winning probability of the normal lottery in the improved entrance rate may be 100% or may be almost 100% (there is a gap).

  -The variation time of the normal symbol variation game may be the same in the non-entrance rate improvement state and in the increase rate. In other words, it is not necessary to shorten the fluctuation time of the normal symbol variation game during the improved entrance rate compared to the variation time of the normal symbol variation game during the non-entry rate improvement state. In another example in which the winning probability of the normal winning lottery in the above-described non-entrance rate improvement state is zero, the variation time of the normal symbol variation game may be always a short variation time (short variation). This always-on example includes fluctuations in the non-entrance rate improvement state and fluctuations in the entrance rate improvement state. Furthermore, the winning probability of the normal lottery in the improvement rate is almost 100% ( In the case of “displacement”, it includes fluctuations in the state of improved entrance rate. Further, the short variation time may be set to be the same or substantially the same as the shortest variation time in the special symbol variation game, or may be set to be shorter than the shortest variation time in the special symbol variation game.

  -In addition, in another example in which the winning probability of the normal lottery in the above-described non-entry rate improvement state is zero, the variation time of the normal symbol variation game in the improved entry rate state is indicated in the non-entry rate improvement state. It may be shortened as compared to the fluctuation time of the normal symbol fluctuation game at.

  The sub-control board 31 is a sub-control board, and separately from the sub-control board 31, a display control board that specially controls the effect display device 11, a light-emission control board that specially controls the decorative lamp La, and a speaker Sp. An audio control board may be provided. Such a sub-control board and a board for controlling other effects may be included as sub-control boards.

  Further, the main control CPU 30a of the main control board 30 and the sub control CPU 31a of the sub control board 31 may be mounted on a single board. In the above-described another example, the display control board, the light emission control board, and the sound control board may be arbitrarily combined to form a single board or a plurality of boards.

  -Arrangement of the big winning opening in the game board YB may be arbitrarily changed. For example, in the case where a plurality of big prize winning openings are provided, the plurality of big winning prize openings may be arranged vertically. In addition, when a single big prize opening is provided, the big prize opening may be arranged below the effect display device 11.

Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
