As shown in FIG. 1, a pachinko gaming machine 10 as a gaming machine is provided with a gaming board YB. On the front side of the pachinko gaming machine 10, a launch handle HD that is operated by the player when launching a game ball onto the game board YB is disposed. In the center of the game board YB, an effect display device 11 having an image display unit GH is provided. The image display unit GH of the effect display device 11 is, for example, a liquid crystal display type display unit. The effect display device 11 displays various effects using images, such as a symbol variation game using decorative symbols (effect symbols). In addition, the pachinko gaming machine 10 is provided with a decorative lamp La that performs a light emission effect. The decoration lamp La is disposed on a frame (for example, a front frame) or the game board YB constituting the pachinko gaming machine 10. In addition, the pachinko gaming machine 10 is provided with a speaker (sound output unit) Sp that outputs various sounds such as sound effects and music and performs sound effects.

The game board YB is provided with a plurality of winning openings (entrance entrances) through which game balls can enter. The winning opening includes a first starting opening 12, a second starting opening 13, and a big winning opening 14.
The first start opening 12 is a winning opening through which a game ball is inserted when the start condition of the symbol variation game is established. In this embodiment, the first start port 12 is located below the effect display device 11, and is always opened so that a game ball can be entered. 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 first start port 12, and the game ball that has entered the first start port 12 is detected in the ball passage. A sensor (starting sensor SE1 shown in FIG. 3) is provided.

  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 below the first start port 12. The second starting port 13 allows a game ball to enter or enter when the opening / closing blade (ordinary electric accessory) 15 opens when a predetermined condition is satisfied (when a normal symbol is won). It is opened for easy. On the other hand, the second starting port 13 is closed so that the opening and closing blades 15 cannot close the game balls due to the closing operation. The opening / closing blade 15 operates by receiving power from an actuator (solenoid, motor, etc.). In this embodiment, the actuator for operating the opening / closing blade 15 is a normal electric accessory solenoid SOL1 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. A sensor to be detected (starting sensor SE2 shown in FIG. 3) is disposed.

  The large winning opening 14 is a winning opening through which a game ball is inserted when the payout condition for the winning ball is established. In this embodiment, the special winning opening 14 is located below the second start opening 13. The big winning opening 14 is opened so that a game ball can be entered by opening the big winning opening door 16 when the big winning lottery is won. On the other hand, the special winning opening 14 is closed so that the special winning entry door 16 cannot close a gaming ball by performing a closing operation. The grand prize winning door 16 operates by receiving power from an actuator (such as a solenoid or a motor). In this embodiment, the actuator for operating the special winning opening door 16 is a special winning solenoid SOL2 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 grand prize opening 14, and a game ball that has entered the big prize opening 14 is detected in the ball passage. A sensor (count sensor SE3 shown in FIG. 3) is provided.

  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 big prize opening 14. In one round game, the grand prize winning door 16 is opened in a predetermined opening mode. One round game is completed when the end condition of the round game is satisfied by the number of balls entered during the round game or the elapsed time of the round game. In this embodiment, the number of entered balls that satisfy the end condition of the round game is “8 balls”, and the elapsed time of the round game that satisfies the end condition of the round game is “25 seconds”.

  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.

  An operation gate 17 is disposed on the game board YB. In this embodiment, the operation gate 17 is located on the left side of the effect display device 11. The operating gate 17 is opened with a gate port 17a that is open so that a game ball can be always entered. A sensor (gate sensor GS shown in FIG. 3) for detecting a game ball that enters and passes through the gate port 17a is disposed. The gate port 17a of the operation gate 17 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 established. The opening / closing blade 15 of the second starting port 13 is won by a normal symbol winning lottery performed by a game ball entering the operating gate 17, and after the normal symbol winning symbol is derived in the normal symbol variation game, Operates from closed to open.

  The game board YB is provided with special symbol display devices 18a and 18b, hold display devices 19a and 19b, and a normal symbol display device 20 shown in FIG. These display devices are located in a portion of the game board YB that is visible to the player when the pachinko gaming machine 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 18a and 18b 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. When a game ball enters the first start port 12 and is detected, the start condition of the symbol variation game using the first special symbol is established when the ball is detected. 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 using the second special symbol is established when the ball is detected. 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. On the other hand, in the first special symbol and the second special symbol, the type of jackpot determined when winning the jackpot lottery and the determination ratio of jackpot of the same type are different. As a result, the first special symbol and the second special symbol have different advantages (for example, the number of prize balls, the period of grant of the improved entrance rate, etc.) when winning the big hit lottery.

  When the start condition is satisfied, a special symbol display game is performed on the special symbol display devices 18a and 18b in order to derive the lottery result of the big hit lottery, and the special symbol derived from the symbol variation game is also generated. The symbol variation game for deriving the result according to is also performed on the effect display device 11 using the decorative symbols.

  In this embodiment, the special symbol display devices 18a and 18b are both 7-segment display devices. In the special symbol variation game, a combination of light emitters constituting a 7-segment 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, in a symbol variation game using decorative symbols, combinations of decorative symbols in a plurality of rows are derived. The decorative design is composed of, for example, a design imitating Arabic numerals. Then, the combination where all the decorative symbols in all the rows become the same decorative symbol is selected as the big hit lottery combination, and the combination where the decorative symbols in all the rows do not become the same decorative symbol is won in the big hit lottery. This is a combination of outliers that can be identified.

  The result derived in the decorative symbol variation game corresponds to the result derived in the special symbol variation game. For this reason, in the special symbol variation game, the lottery result of the big hit lottery is derived as a special symbol, while in the decorative symbol variation game, information that can identify the lottery result of the big hit lottery is derived as a decorative symbol.

  The hold display devices 19a and 19b display the number of symbol change games (starting hold number) of special symbols whose execution is being held. The normal symbol display device 20 performs a normal symbol variation game using the normal symbol, and a normal symbol corresponding to the lottery result of the normal symbol winning lottery is derived in the normal symbol variation game.

  As shown in FIG. 1, the pachinko gaming machine 10 is provided with an operation button BT1 as an operation means that can be operated by the player. In this embodiment, the operation button BT1 is disposed on the upper surface of the storage tray 21 for storing game balls. The operation button BT1 is a push button type. The operation button BT1 of this embodiment has one operation unit. The operation unit is a part where the player performs a pressing operation.

FIG. 2 shows the decorative symbols used in the decorative symbol variation game.
In this embodiment, the decorative symbol design variation game derives a combination of three decorative symbols including the left column ZL, the middle column ZC, and the right column ZR. The decorative pattern in each row is configured with a design imitating Arabic numerals [1] to [8]. That is, in each row, there are eight types of decorative symbols that can be derived from combinations of decorative symbols.

  Each ornamental pattern imitating Arabic numerals [1] to [8] is configured so that Arabic numerals can be distinguished and specified from their outlines. The outline is a line that forms the outer shape of the object. For example, the Arabic numerals [6] and [8] require a circular inner shape line in addition to the outer shape line. For this reason, the outline includes an outer shape line and an inner shape line. Each of the decorative designs is given a predetermined pattern in a predetermined color. In this embodiment, among the odd symbols of [1], [3], [5], and [7], [1] and [5] are given the same pattern in the same color, and [3] [7] has the same pattern with the same color. The patterns and colors of [1] and [5] are different from the patterns and colors of [3] and [7]. The same pattern is given the same color to the even symbols [2], [4], [6], and [8]. The patterns and colors of [2], [4], [6] and [8] are different from the patterns and colors of [1], [3], [5] and [7].

  Thereby, the decorative design of this embodiment can recognize the number which each decorative design means by the outline, and can distinguish a number. In addition, the decorative symbol of this embodiment can recognize the grouping of symbols, that is, the relevance of decorative symbols imitating different numbers, from the identity of the pattern and color. More specifically, the eight types of decorative patterns of this embodiment are the first odd group of [1] and [5], the second odd group of [3] and [7], [2] and [ 4], [6] and [8] can be recognized.

  In this embodiment, the decorative symbol group is a group representing the level of expectation of jackpot. In the decorative symbol variation game, reach is formed by deriving the same decorative symbols in a predetermined plurality of columns (two columns of the left column ZL and the right column ZR in this embodiment), and the remaining columns (this implementation) In the form, a reach effect for deriving one row of the middle row ZC) is performed. Then, the group representing the level of expectation of the big hit by the decorative design described above can make the player recognize the level of the degree of expectation of the big hit when derived as the reach formation design. In this embodiment, the decorative symbol belonging to the second odd group is the decorative symbol having the highest jackpot expectation level, and the decorative symbol belonging to the first odd group is higher than the even number group. Has been. In the above three groups, the decorative symbols belonging to the second odd group may be positioned so that a probability variation state to be described later is given in addition to the position with the highest expectation degree for the big hit. .

  Returning to the description of the pachinko gaming machine 10, the pachinko gaming machine 10 of this embodiment has a probability variation function. The probability variation function is a function that can provide a probability variation state in which the winning probability of the jackpot is changed from a low probability (normal probability) to a high probability after the jackpot game ends. The probability variation state is given, for example, until the next big hit lottery is won. The probability variation state is a game state that is more advantageous to the player because it is easier to win the big hit lottery than the non-probability variation state in which the winning probability of the big hit lottery is low.

  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 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 open / close blades 15 based on winning the normal symbol winning lottery is made longer than that in the non-entrance rate improvement state. In addition, as the opening time extension control, the number of times of opening the opening and closing blade 15 based on the fact that the normal symbol winning lottery is won, and the normal symbol winning lottery is won more than in the non-entry rate improvement state. At least one of the controls for making the opening time of the opening / closing blade 15 longer than that in the non-entrance rate improvement state may be executed. 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”.

  The entrance rate improvement state is, for example, until the next big hit lottery is won or until the specified symbol number up to the specified upper limit number of times (for example, 100 times) is executed after the entrance rate improvement state is given. Or, until it reaches the big hit lottery before reaching the specified upper limit number of times. In the case of the pachinko gaming machine 10 using the first special symbol and the second special symbol, the specified upper limit number 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 the main control board 30 and the sub control board 31 shown in FIG.
The main control board 30 includes a main control CPU 30a capable of executing control operations in a predetermined procedure, a main control ROM 30b for storing control information such as a control program for the main control CPU 30a, and writing of necessary data. A main control RAM 30c capable of reading. The main control board 30 has a random number generation circuit 30d.

  Detection signals from various sensors SE1, SE2, CS, and GS are input to the main control CPU 30a. The main control CPU 30a controls display contents of various display devices (special symbol display devices 18a and 18b, hold display devices 19a and 19b, normal symbol display device 20 and the like) and various actuators (ordinary electric accessory solenoids). The operation of SOL1, the big winning solenoid SOL2) is controlled.

  The control information stored in the main control ROM 30b includes a main control program for executing processing related to the game, information for specifying a special symbol variation pattern (main variation pattern), various determination values, and the like. The main variation pattern can specify the 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 in which a reach effect is performed in a decorative symbol variation game, and a variation in which a reach effect is not performed in a decorative symbol variation game. In addition, the various determination values include a big hit determination value used for the big win lottery, a normal hit determination value used for the normal symbol win 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 main 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 number is a big hit random number used for a special symbol jackpot lottery or a normal hit random number used for a normal symbol hit lottery.

  As shown in FIG. 3, the sub control board 31 is electrically connected to the main control board 30 so that 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 that can execute control operations in a predetermined procedure, a sub-control ROM 31b that stores a control program for the sub-control CPU 31a, and a sub-control that can write and read necessary data. And a control RAM 31c.

  The sub control CPU 31a of the sub control board 31 performs control according to the information based on the information transmitted from the main control board 30. For example, when starting the special symbol changing game, the main control CPU 30a sub-controls information indicating the start of the change (start of the game) in addition to the control of the display contents of the special symbol display devices 18a and 18b. To the CPU 31a. Receiving the 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 decoration symbols. Further, the sub-control CPU 31a changes the light emission mode of the decoration lamp La and the sound output mode of the speaker Sp so as to perform the light emission effect and the sound effect accompanying the symbol variable game with the start of the decorative symbol pattern variation game. Control.

  Further, a detection signal of the operation button BT1 is input to the sub control board 31. The operation button BT1 includes a detection unit K1 that detects an operation state. When the operation button BT1 is pressed, the detection unit K1 outputs a detection signal that can identify the operation. The detection unit K1 is, for example, a proximity sensor or a contact type switch that can output an electrical signal, and constitutes a detection unit. The detection signal is a binary signal consisting of ON / OFF.

Next, the contents of control executed by the main control board 30 will be described.
The main control CPU 30a of the main control board 30 executes various processes such as a special symbol input process and a special symbol start process based on the main control program. The main control CPU 30a executes various processes such as a special symbol input process and a special symbol start process every predetermined control period (for example, 4 ms).

First, the special symbol input process will be described.
The main control CPU 30 a determines whether a game ball has entered the first start port 12 or the second start port 13. In this determination, the main control CPU 30a determines that a game ball has entered the first start port 12 by inputting the detection signal from the first start sensor SE1, and receives the detection signal from the second start sensor SE2. By inputting, it is determined that a game ball has entered the second start port 13.

  When a game ball enters the first start port 12, the main control CPU 30a determines whether or not the number of start suspensions of the first special symbol is less than the upper limit number (4 in this embodiment). 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 after the addition so as to display the start hold number. To control. Further, when a game ball enters the second start port 13, the main control CPU 30 a determines whether or not the number of start suspensions of the second special symbol is less than the upper limit number (4 in this embodiment). The main control CPU 30a 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 19b after the addition. To control. Note that the main control CPU 30a ends the special symbol input process without adding the start hold number when the start hold number reaches the upper limit number. In addition, when the start suspension number is added, the main control CPU 30a outputs information (such as a hold designation command) that can specify the added start suspension number to the sub-control board 31. The sub-control CPU 31a, which has input information that can specify the number of start suspensions, displays an image indicating the number of start suspensions that can be specified from the information on the image display unit GH.

  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. In this process, the main control CPU 30a obtains a jackpot random number value from the random number generation circuit 30d, and obtains a jackpot symbol random number value and a variation pattern distribution random number value from the main control RAM 30c. Thereafter, the main control CPU 30a ends the special symbol input process.

Next, the special symbol start process will be described.
The main control CPU 30a determines whether the start condition of the special symbol changing game is satisfied. In this determination, the main control CPU 30a determines that the start condition is satisfied when the symbol variation game is not being executed and is not in the big hit game, while the symbol fluctuation game is being executed or in the big hit game. In this case, it is determined that the start condition is not satisfied. Then, the main control CPU 30a ends the special symbol start process when the start condition is not satisfied.

  When the 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 larger than 0 (zero). Then, when the number of pending start of the second special symbol is larger than 0 (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 0 (zero), and is the read start hold number larger than 0 (zero)? Determine. When the number of reserved start of the first special symbol is larger than 0 (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 0 (zero), the main control CPU 30a performs a process for executing a demonstration effect. The demonstration effect is an effect for notifying that the pachinko gaming machine 10 is in a standby state using, for example, a device such as the effect display device 11 and obtaining a guest-coming effect.

  When starting the symbol variation game of the second special symbol, the main control CPU 30a rewrites the start hold number of the second special symbol by 1 and rewrites it, and displays the hold start number 19b after subtraction. To control. Further, when subtracting the start suspension number, the main control CPU 30a outputs information (such as a suspension 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. Then, 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 jackpot lottery, the jackpot is won when the value of the jackpot random number matches the jackpot determination value.

  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. Further, the main control CPU 30a determines the variation pattern for the big hit variation based on the value of the variation pattern distribution random number specified from the acquired random number information.

  On the other hand, when the big hit lottery is not won, the main control CPU 30a performs a loss process. 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.

  In the deviation processing, the main control CPU 30a determines a main fluctuation pattern without reach or a main fluctuation pattern with reach from the main fluctuation patterns for deviation fluctuation. In this determination, for example, a reach determination for determining whether or not a reach effect is performed may be performed, and a main variation pattern with reach or a main variation pattern without reach may be determined based on the determination result. In this case, the variation pattern distribution random numbers are allocated to the main variation pattern classification with reach and the main variation pattern classification without reach. If it is determined that the reach effect is to be performed in the reach determination, the variation pattern is determined from the main variation pattern with reach according to the variation pattern distribution random number, while the reach effect is not performed in the reach determination. If it is determined, the variation pattern is determined according to the variation pattern distribution random number from the main variation patterns without reach. In addition, as another method, without performing reach determination, a variation pattern is determined according to a variation pattern distribution random number from the main variation pattern for outlier variation including the main variation pattern with reach and the main variation pattern without reach. decide. According to this determination method, since the reach determination is not performed, whether or not the reach effect is performed is determined by determining the main fluctuation pattern. It should be noted that which determination method is adopted is determined by the specifications of the pachinko gaming machine.

  On the other hand, when starting the symbol variation game of the first special symbol, the main control CPU 30a performs the same control as the control of the second special symbol described above on the first special symbol. In other words, the main control CPU 30a performs subtraction of the number of start suspensions of the first special symbol, jackpot lottery, jackpot processing or deviation processing based on the results of jackpot lottery.

  Then, the main control CPU 30a that has performed the big hit process or the off process as described above executes a process such as outputting predetermined information (control command) to the sub control board 31 at a predetermined timing. First, the main control CPU 30a outputs a variation pattern designation command for instructing the variation pattern and instructing the start of variation. Further, the main control CPU 30a controls the display content of the special symbol display device 18a or the special symbol display device 18b so as to start the variation of the first special symbol or the second special symbol. Further, the main control CPU 30a starts measuring the variation time of the special symbol variation game. Further, the main control CPU 30a outputs a special symbol designation command for designating a special symbol.

  Note that, in a process different from the special symbol start process, the main control CPU 30a causes the special symbol display device 18a to derive the determined special symbol when the variation time determined in the designated variation pattern has elapsed. Alternatively, the display content of the special symbol display device 18b is controlled. Further, the main control CPU 30a outputs an all symbol stop command for instructing the stop of the fluctuation when the fluctuation time determined in the designated fluctuation pattern has elapsed.

  In addition to the special symbol input process and the special symbol start process described above, the main control CPU 30a performs a process related to the big hit game, a process related to the gaming state, and a process related to the normal symbol. In the process related to the big hit game, the process of opening and closing the big prize opening 14 and the counting process of the game balls that have entered the big prize opening 14 based on the detection signal from the count sensor CS are performed. In the process relating to the gaming state, a process of assigning a probability variation state or an entrance rate improvement state is performed. For example, the gaming state after the big hit game is associated with the type of big hit symbol determined when the big hit lottery is won. In other words, in the pachinko gaming machine 10 of this embodiment, determining the jackpot symbol is equivalent to determining the type of jackpot, and the main control CPU 30a plays the jackpot game in the gaming state corresponding to the determined jackpot type. Control the gaming state after the end. In the processing related to the normal symbol, processing for inputting a detection signal from the gate sensor GS, processing for starting a normal symbol variation game, and the like are performed.

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

First, the decorative symbol variation process will be described.
In the decorative symbol variation process, when the special designating command is input, the sub control CPU 31a determines a combination of decorative symbols to be derived in the decorative symbol variation game based on the special symbol designated by the special symbol designation command. The sub-control CPU 31a determines a combination of jackpots based on decorative symbols when a special symbol jackpot symbol is designated. In addition, when a special symbol off symbol is designated, the sub control CPU 31a determines a combination of decorative symbols to be derived in the decorative symbol variation game based on the variation pattern designated by the variation pattern designation command. . More specifically, the sub control CPU 31a determines a combination of deviation including a reach formation symbol when a main fluctuation pattern for deviation fluctuation with reach is designated. Further, the sub control CPU 31a determines a combination of detachment that does not include a reach formation symbol when a main variation pattern for detachment variation without reach is designated.

  In the decorative symbol variation game, reach is formed by deriving the same decorative symbols in a predetermined plurality of columns (two columns of the left column ZL and the right column ZR in this embodiment), and the remaining columns (this implementation) In the form, a reach effect for deriving one of the middle rows) is performed. For this reason, the same decorative design derived in a predetermined plurality of columns becomes a reach forming symbol, and in the combination of detachment including a reach forming symbol, the predetermined multiple columns are the same decorative symbol, and the remaining columns are the predetermined plural The combination is a decorative pattern different from the decorative pattern of the row. Further, the combination of outliers not including the reach forming symbol is a symbol in which a predetermined plurality of columns are different, and the remaining columns are combinations regardless of the coincidence with the predetermined plurality of decorative symbols. Incidentally, the combination of jackpots in this embodiment is a combination in which the decorative symbols of all the rows become the same decorative symbols. In other words, the jackpot combination includes a reach formation symbol.

  Further, when the change pattern designation command is input, 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 contents of the effect of the symbol variation game with a decorative symbol.

The contents of the effect of the symbol variation game that can be specified from the sub variation pattern include the following effects.
For example, for an out-of-order production content that does not perform reach production, for example, the variation of decorative designs in 3 rows is stopped in a predetermined order (for example, left row → right row → middle row), and finally reach formation symbols are displayed. There is production content that derives combinations of outliers that are not included. In addition, the contents for performing the reach effect include an effect content for performing the normal reach effect and an effect content for performing the super reach effect. The normal reach effect is an effect of deriving a combination of decorative symbols by deriving the same decorative symbol in a predetermined plurality of columns to form a reach, and then stopping the fluctuation of the remaining columns. The super reach effect is an effect in which the design of the remaining rows is derived by the normal reach effect, or the effect is developed in the middle of the normal reach effect, and the combination of the decorative symbols is derived by the effect after the development. The super reach production is positioned as a production with a high expectation level for big hits compared to the normal reach production. The jackpot expectation degree can be calculated by the ratio of the appearance rate in the case of jackpot to the overall appearance rate, which is the sum of the appearance rate in the case of loss and the appearance rate in the case of jackpot. In the case where a plurality of types of super reach effects are provided, the jackpot expectation may be different for each type of super reach effects.

  The sub control CPU 31a that has determined the sub variation pattern controls the display content of the effect display device 11 so that the decorative symbol design variation game is displayed with the effect content specified by the sub variation pattern. Then, the sub-control CPU 31a controls the display content of the effect display device 11 so as to end the decorative symbol variation game and derive the decorative symbol combination as the variation time specified from the main variation pattern elapses. . In this embodiment, the sub-control CPU 31a functions as an effect control means that can control effects including a symbol change game of decorative symbols and effects (sound output and light emission) associated with the symbol change game. In this embodiment, the decorative symbol variation game is terminated with the input of all symbol stop commands, but the variation time specified from the main variation pattern is counted under the control of the sub-control CPU 31a. You may make it complete | finish the design change game of a decoration design. That is, the end of the decorative symbol variation game may be controlled without outputting the all symbol stop command from the main control board 30.

In the pachinko gaming machine 10 according to the present embodiment configured as described above, an image can be displayed on the image display unit GH during the decorative symbol variation game, and an effect can be executed.
FIG. 4 illustrates an effect that is executed by displaying an image in the display area H of the image display unit GH. The display area H of the image display unit GH indicates the entire area in which an image can be displayed on the display if it is a liquid crystal display, and is at least visible when the pachinko gaming machine 10 is viewed from the front as shown in FIG. It is.

The effect illustrated in FIG. 4A is an effect using the operation button BT1.
In this effect, when the operation button BT1 is operated during the decorative symbol variation game, the window image G1 is displayed in the display area H of the image display unit GH in response to the operation, and for example, a character is displayed in the window image G1. Is. The window image G1 is displayed so as to overlap the background image HK displayed on the image display unit GH and the front side of the decorative pattern during the variable display. And such an effect is performed as a kind of notice effect which announces a jackpot expectation degree, for example. Note that the image displayed in the window image G1 may be a still image or a moving image.

  The effect illustrated in FIG. 4B is an effect in which a plurality of window images G2 and G3 are displayed in the display area H of the image display unit GH. In this effect, for example, a character is displayed on each of the window images G2 and G3, and a character image indicating the conversation content is displayed as if the character of the window image G2 and the character of the window image G3 are talking. . Each of the window images G2 and G3 is displayed so as to overlap the front side of the background image HK displayed on the image display unit GH and the decorative pattern during the variable display. And such an effect is performed as a kind of notice effect which announces a jackpot expectation degree, for example.

  The pachinko gaming machine 10 according to this embodiment uses an effect different from the effect illustrated in FIGS. 4A and 4B as an effect using the display area H of the image display unit GH (hereinafter referred to as “image effect”). Is configured to be executable.

FIGS. 5A to 5E show examples of image effects executed in this embodiment.
As shown in FIG. 5A, symbol display positions P1, P2, and P3 for stopping and displaying decorative symbols in each column are defined in the image display unit GH. The symbol display position P1 is a position where the decorative symbols in the left column ZL are stopped and displayed, the symbol display position P2 is a position where the decorative symbols in the middle row ZC are stopped, and the symbol display position P3 is a symbol where the decorative symbols in the right column ZR are displayed. This is the stop display position. The stop display includes a stop display and a fixed stop display. The once-stop display is a display form of a decorative symbol at a stage where the result of the symbol variation game is not fixed. On the other hand, the fixed stop display is a display form of decorative symbols at the stage where the result of the symbol variation game is fixed. The variation of each column in the decorative symbol variation game is a display form in which a plurality of types of decorative symbols sequentially pass through the symbol display positions P1 to P3. In this embodiment, as shown in FIG. 2, the decorative symbols of each column fluctuate in ascending order in the direction of arrow A, and the vertical direction so that the symbol display positions P1 to P3 cross the vertical direction of the image display unit GH. Fluctuates to scroll.

  A background image HK is displayed on the image display unit GH. The background image HK is not limited to a still image, but may be a moving image in which, for example, a part of a cloud moves over time if the background image HK simulates the sky. In the figure, the background image HK is schematically shown by a diagonally downward slanting line. The decorative symbol design variation game is displayed so as to overlap the front side of the background image HK, and the decorative symbols of each column are stopped and displayed so as to overlap the front side of the background image HK as shown in FIG.

Here, before explaining the details of the image effect executed in this embodiment, an outline of the image effect will be described.
In the image effect, in the decorative symbol design variation game, a boundary portion K that creates a boundary with the background image HK appears in the display area H of the image display portion GH, and a part of the image display portion GH created by the boundary portion K. This is executed by displaying another image distinct from the background image HK in the display area Ha. And in this embodiment, the boundary part K is comprised by the outline part of the decorative design, and the part enclosed by the outline part is equivalent to a part display area Ha of the image display part GH produced by the boundary part K. In the display area Ha, another image different from the background image HK is displayed. In other words, the decorative design of this embodiment forms a region closed by the outline (only the outline line, or the outline line and the internal line), and the closed area corresponds to the display area Ha.

Hereinafter, the image effects illustrated in FIGS. 5A to 5E will be described in detail. For convenience of explanation, the image effects illustrated in FIGS. 5A to 5E are referred to as first image effects.
FIG. 5A shows a state where the combination of the decorative pattern [738] is stopped and displayed on the image display unit GH. As shown in FIG. 2, the decorative design when the image effect is not executed is a state in which numbers can be distinguished by the contours and a predetermined pattern is applied in a predetermined color.

  Then, in the decorative symbol pattern change game in which the first image effect is executed, when the change is started, the patterns and colors of each decorative symbol of [738] are lost, and the decorative symbol changes only to the outline portion. That is, the state in which only the outline portion is left is a state in which the boundary portion K that creates the boundary with the background image HK appears in the display area H of the image display portion GH. In addition, due to the appearance of the boundary portion K, a portion where the original pattern and color are applied appears as a partial display area Ha of the image display portion GH.

  Note that the decorative design [738] of each column is in a state in which the type of the design can be distinguished even if the pattern and color disappear because the outline portion remains. In the first image effect, a plurality of boundary portions K appear at a time by setting all three rows of decorative symbols to only the contour portion.

  In the first image effect, as shown in FIG. 5 (b), the effect image M1 is distinguished from the background image HK (downward slanted line) in the display area Ha of each decorative design surrounded by the outline portion. Is displayed. The effect image M1 is a single image connected by three display areas Ha, and the single image is divided and displayed in each display area Ha. That is, in the first image effect, only the portion of the effect image M1 that overlaps each display area Ha when the effect image M1 is displayed on the screen, with the three display areas Ha formed by the decorative symbols in each row viewed on the screen. Is executed in a manner that can be visually recognized. For this reason, since the effect image M1 is divided and displayed in the three display areas Ha, different images are displayed.

  Further, in the first image effect, as shown in FIG. 5C, a change occurs in the effect image M1 displayed in FIG. This example effect image M1 is an image imitating a cat. The effect image M1 changes from a striped cat (FIG. 5B) to a spotted cat (FIG. 5C). That is, due to the change in the effect image M1, in the first image effect, a continuous image is displayed in the display area Ha of each decorative design surrounded by the outline portion. The effect of displaying these continuous images is a special effect. The effect image M1 itself may be a still image or a moving image. As shown in this example, when the effect image M1 is a cat, the cat may be performing some operation in the process of displaying continuous images. In the effect image M1, for example, a certain character appears, a process in which the character holds a gun and shoots a gun is displayed, or a depiction angle of an airship or the like is changed (for example, front → right side → left side). It may be an image with continuous motion such as a surface.

  Further, when a continuous image is displayed in the first image effect, the display area Ha of each decorative design is in a stationary state as shown in FIGS. The stationary state here is a state in which the decorative symbol is temporarily stopped. The temporary stop display includes, for example, a so-called fluctuation fluctuation state in which the decorative design is moved up and down or left and right. Further, when a continuous image is displayed in the first image effect, the area size of the display area Ha of each decorative design is fixed as shown in FIGS. That is, when the effect image M1 is displayed in the first image effect, the effect image M1 is changed, but the decorative pattern itself forming the display area Ha does not change and is constant.

  And after the 1st image effect illustrated as mentioned above, the image display part GH starts the fluctuation | variation of the decorative design of each row | line | column. In the pachinko gaming machine 10 of this embodiment, as shown in FIG. 5 (d), the decorative symbols in each row are temporarily placed in the direction opposite to the direction of change (the direction indicated by the white arrow in FIG. 5 (e)). After quantifying and moving, the decorative design is changed in the changing direction.

  As shown in FIG. 5D, when the decorative symbols in each column move in the direction opposite to the fluctuation direction, the effect image M1 is displayed in accordance with the movement of the contour portion (boundary portion K) of the decorative symbols in each column. Each display area Ha is also moved. At this time, in each display area Ha, the effect image M1 is displayed following the outline portion of the decorative pattern in each column. Specifically, the display position of the effect image M1 is fixed in the display area H of the image display unit GH, and each display area Ha and the effect image M1 overlap each other when the contour portion of each column moves. Deviation occurs. For this reason, in each display area Ha after movement, a portion of the effect image M1 that is overlapped when shifted is displayed. In addition, when the outline part of the decorative pattern of each column moves, a shift | offset | difference will arise in the boundary part with the background image HK currently displayed on the image display part GH, but the image display part which appeared when it moved A background image HK is displayed in the display area H of GH.

  Thereafter, as shown in FIG. 5E, in the image display unit GH, the decorative design of each column is changed. Each decorative pattern that is changing has returned to its original pattern and color. That is, the display area Ha surrounded by the outline portion of the decorative design disappears. In the decorative symbol design variation game, a combination of decorative symbols corresponding to the lottery result of the big hit lottery is derived. In other words, if the jackpot lottery is won, the jackpot combination is displayed in a fixed stop state. On the other hand, if the big hit lottery is not won, the combination of losing is displayed as a fixed stop.

6A to 6E show examples of image effects executed in this embodiment.
Hereinafter, the image effects illustrated in FIGS. 6A to 6E will be described in detail. For convenience of explanation, the image effects illustrated in FIGS. 6A to 6E are referred to as second image effects. Similarly to the first image effect, in the second image effect, a boundary portion K that creates a boundary with the background image HK appears in the display area H of the image display portion GH in the decorative symbol variation game, and the boundary portion K This is executed by displaying another image, which is distinguished from the background image HK, in a partial display area Ha of the image display unit GH created by the above. For this reason, in the description of the second image effect, the description overlapping with the first image effect is omitted or simplified.

  FIG. 6A shows a state in which each row is changed by the start of the decorative symbol change game. FIG. 6B shows a state where the combination of the decorative pattern [738] is stopped and displayed on the image display unit GH due to the change in each column being stopped. As shown in FIG. 2, the decorative design when the image effect is not executed is a state in which numbers can be distinguished by the contours and a predetermined pattern is applied in a predetermined color.

  Then, in the decorative pattern variation game that executes the second image effect, after the decorative pattern combination [738] is stopped and displayed as shown in FIG. 6B, the pattern of each decorative pattern of [738] is displayed. The color disappears, and it changes to a decorative pattern with only the outline. That is, a boundary portion K that creates a boundary with the background image HK appears in the display area H of the image display portion GH. Note that the decorative design [738] of each column is in a state in which the type of the design can be distinguished even if the pattern and color disappear because the outline portion remains. Further, in the second image effect, a plurality of boundary portions K appear at a time by setting all three rows of decorative symbols to only the contour portion.

  In the second image effect, as shown in FIG. 6C, a special display that is distinguished from the background image HK (downward slanted line) is displayed in the display area Ha of each decorative design surrounded by the outline portion. An effect image M2 as an effect is displayed. In the effect image M2, characters C1, C2, and C3 are displayed as predetermined images for each decorative symbol display area Ha, and a notification image HG (“PUSH”) that prompts the user to operate the operation button BT1 is displayed as an image. The That is, the second image effect in this embodiment is an effect using the operation button BT1 as an operation means that can be operated by the player. The notification image HG that prompts the operation of the operation button BT1 is displayed in a part of each display area Ha created by the contour portion of each decorative design.

  And as shown in FIG.6 (d), by operating operation button BT1, a change will arise in the image of each character C1, C2, C3 currently displayed on the display area Ha of each decoration design. In this example, the characters C1, C2, and C3 are regarded as enemies (lower end characters), and the image is changed to an image in which the enemies (lower end characters) are repelled by operating the operation button BT1.

  Thereafter, as shown in FIG. 6E, the effect image M2 displayed in the display area Ha of each decorative design is deleted, and an image of a new enemy (boss character) is displayed as the background image HK. At this time, each decorative design is maintained in a state in which only the outline portion remains. For this reason, an image of a new enemy (boss character) as the background image HK is visible through each decorative pattern.

  Thereafter, the image display unit GH displays an effect of fighting with the boss character. When the big hit lottery is won, the boss character is won and the big hit combination is confirmed and displayed. On the other hand, when the big hit lottery is not won, the boss character is defeated, and the combination of outliers is confirmed and displayed.

  Note that the second image effect of this embodiment can attack one enemy by operating the operation button BT1 once, and requires three operations to attack everyone. Yes. When three enemies (lower characters) are repelled, a boss character appears and the performance continues as shown in FIG. On the other hand, if the three enemies could not be repelled, the out-of-combination combination [738] derived in FIG.

FIGS. 7A to 7E show an example of an image effect executed in this embodiment.
Hereinafter, the image effects exemplified in FIGS. 7A to 7E will be described in detail. For convenience of explanation, the image effects illustrated in FIGS. 7A to 7E are referred to as third image effects. Similarly to the first and second image effects, the third image effect also has a boundary K that creates a boundary with the background image HK in the display area H of the image display unit GH in the decorative pattern change game. This is executed by displaying another image distinct from the background image HK in a part of the display area Ha of the image display unit GH created by the boundary K. For this reason, in the description of the third image effect, the description overlapping with the first and second image effects is omitted or simplified.

  FIG. 7A shows a state in which each row is changed by the start of the decorative symbol change game. FIG. 7B shows a state in which [7] is stopped and displayed on the image display unit GH due to the change in the left column ZL being stopped. As shown in FIG. 2, the decorative design when the image effect is not executed is a state in which numbers can be distinguished by the contours and a predetermined pattern is applied in a predetermined color.

  Then, in the decorative symbol pattern change game in which the third image effect is executed, as shown in FIG. 7C, the decorative symbol [7] loses its pattern and color and changes to a decorative symbol having only an outline portion. That is, a boundary portion K that creates a boundary with the background image HK appears in the display area H of the image display portion GH. Note that the decorative pattern [7] in the left column ZL is in a state in which the pattern type can be distinguished even if the pattern and color are lost because the outline portion remains. In the third image effect, one line of decorative symbols changes to a decorative pattern with only a contour portion, and the other two columns continue to fluctuate.

  In the third image effect, as shown in FIG. 7C, the display area Ha of the decorative pattern [7] surrounded by the outline portion is distinguished from the background image HK (left-down diagonal line). An image in which the effect image M3 as an image is displayed changes. Specifically, an image imitating the sky is displayed in the display area Ha of the decorative pattern [7], and the image displayed in the display area Ha changes to an image in which a fighter appears. Further, in accordance with the appearance of the fighter, an image of a missile fired to shoot down the fighter is displayed in the display area H of the image display unit GH other than the display area Ha of the decorative pattern [7].

  After that, when the fighter is shot down with a missile as shown in FIG. 7 (d), the background image HK of the image display unit GH changes to the background image HKa as shown in FIG. Fluctuating game continues. Note that when the decorative symbol variation game continues, the left column starts to vary again. In the third image effect, when an image change occurs in the display area Ha surrounded by the outline portion of the decorative pattern (appearance of a fighter), it is displayed before the appearance of the boundary K after the image change. A change also occurs in the image, that is, the background image HK, and the presentation proceeds.

The first to third image effects described above are realized by the control of the sub control board 31 that functions as an image control unit.
The sub-control CPU 31a of the sub-control board 31 selects an image effect to be executed, and reads data necessary for the selected image effect from the sub-control ROM 31b. The sub-control board 31 includes a character ROM that stores character image data to be displayed on the image display unit GH, specifically, a person, a character, a figure, or a symbol (including decorative designs) in advance. Various data may be read out. Then, the sub control CPU 31a outputs the read data to a VDP (video display processor). The VDP executes display control based on the input data and causes the image display unit GH to display an image.

  In this embodiment, each of the first to third image effects is a notice effect for notifying whether or not the decorative symbol variation game accompanying the special symbol variation game is advantageously developed. An advantageous development in this case is to give notice of whether or not it will be a big hit.

  The first image effect is a notice effect at the start of fluctuation. In this embodiment, a plurality of types of effect images M1 as continuous images are provided, and a big hit expectation is determined for each type. The sub-control CPU 31a determines by lottery whether or not to execute the first image effect in the decorative symbol variation process. The winning probability of the first image production lottery is set to a higher probability when winning the jackpot lottery than when not winning the jackpot lottery. Then, the sub-control CPU 31a determines one effect image M1 by lottery from a plurality of types of effect images M1 when winning the first image effect execution lottery. The winning probability of the selection lottery of the first image effect is that the higher the big hit expectation degree is, the easier it is to win the effect image M1 when the big hit lottery is won, and the lower big hit expectation degree is when the big hit lottery is not won It is set so that it is easy to win the effect image M1 that defines.

  The second image effect is a notice effect that is fluctuating, and is an effect that leads to development once a combination of chances (chance) is derived. In this embodiment, the expectation for jackpot is higher when the performance is developed. For this reason, the second image effect informs the expected degree of jackpot.

  The sub control CPU 31a determines by lottery whether or not to execute the second image effect in the decorative symbol variation process. The winning probability of the second image effect execution lottery is set to a higher probability when winning the jackpot lottery than when not winning the jackpot lottery.

  The third image effect is a notice effect that is fluctuating, and is an effect that leads to a background change using a specific row. In this embodiment, a plurality of types of background images are provided, and a big hit expectation is determined for each background image. For this reason, the third image effect informs the expected degree of jackpot.

  The sub control CPU 31a determines by lottery whether or not to execute the third image effect in the decorative symbol variation process. The winning probability of the third image effect execution lottery is set to a higher probability when winning the jackpot lottery than when not winning the jackpot lottery.

Therefore, according to this embodiment, the following effects can be obtained.
(1) By displaying a continuous image (effect image M1) distinguished from the background image HK in a part of the display area Ha of the image display portion GH created by the boundary portion K, the display of the continuous image is performed. Can be emphasized. Therefore, in addition to the development of the background image HK and the symbol variation game displayed on the image display unit GH, the player's attention is drawn to another image (effect image M1) that suddenly appears in a part of the background image HK. Can improve the interest.

  (2) By determining the big hit expectation level for consecutive images (effect image M1), it is possible to attract the player's attention as to what image is displayed, and to improve the interest.

  (3) By having a plurality of types of boundary portions K, it is possible to cause a change in the display area Ha created by the boundary portions K. As a result, the player's attention can be gathered as to what kind of boundary portion K appears, and the interest can be improved. In this embodiment, there are a plurality of types of boundary portions K due to the difference in the outline of the decorative design.

(4) By enclosing the display area Ha on which a continuous image (effect image M1) is displayed with the boundary portion K, the portion to be noted can be expressed more clearly.
(5) By displaying a plurality of boundary portions K and displaying a continuous image in each display area Ha, it is possible to diversify the portions that should be noticed by the player, and to realize more interesting effects.

  (6) Since a part of the continuous image (effect image M1) is divided in units of the display area Ha, it is possible to attract more attention to what image is displayed. That is, it is possible to visually recognize an image while connecting the images displayed in the display areas Ha and imagining an overall image. Further, by using a plurality of display areas Ha, it is possible to secure a wide display area of continuous images, and to ensure visibility.

(7) Also, since different continuous images (effect images M1) are displayed for each display area Ha, it is possible to diversify the portions that should be noticed by the player, and to realize more interesting effects.
(8) By displaying a continuous image in the display area Ha so as to follow the movement of the boundary K, it is possible to realize an effect without a sense of incongruity.

  (9) Since the first image effect is started with the plurality of display areas Ha being stationary, it is possible to improve the visibility of the continuous images (effect image M1) displayed in each display area Ha. it can. That is, if the display area Ha moves around in the image display unit GH, it is difficult to understand what kind of image it is because it is a continuous image. For this reason, the meaning of the displayed image can be conveyed to the player by starting the first image effect in a state where each display area Ha is stationary.

  (10) In the first image effect, the plurality of display areas Ha have a fixed area size while a continuous image (effect image M1) is displayed. When the area size changes, the visible area changes, leading to a decrease in the visibility of continuous images displayed in the display area Ha. For this reason, the fall of the visibility of an image can be suppressed by fixing the area | region size of the display area Ha while the continuous image is displayed.

  (11) Since the boundary portion K is the contour portion of the decorative symbol and the display area Ha is formed in the portion surrounded by the contour portion, the original meaning of the decorative symbol is maintained and the display of the decorative symbol is performed in parallel. The first to third image effects can be executed. Since the decorative design is displayed in a relatively large size in the image display unit GH, the display size of the images of the first to third image effects can be ensured according to the size of the decorative design. Visibility can be improved.

  (12) The design (decorative design) originally has a different meaning. For example, in the case of a numerical design, the numbers to be represented are different, such as [1] to [9], and the design, that is, the outline (shape) is different, so that it can be identified. For this reason, forming the display area Ha in the part surrounded by the outline part of the design means that the display area Ha having a different shape depends on what kind of design is displayed at the stage of starting the first to third image effects. Will be formed. For this reason, a change arises in the display mode of the image in each display area Ha, and a more interesting effect can be realized. In particular, in the case of the first image effect, a change in the display mode of the continuous image (the range in which the image can be seen) occurs depending on what display area Ha is formed, and a more interesting effect can be realized.

  (13) By displaying the second image effect using the operation button BT1 in a part of the display area Ha of the image display unit GH created by the boundary portion K, the display of the second image effect can be emphasized. it can. Therefore, in addition to the development of the background image HK and the design variation game displayed on the image display unit GH, it is possible to attract the player's attention to another image that suddenly appears in a part of the background image HK. Improvements can be made.

  (14) The notification image HG that prompts the operation of the operation button BT1 is displayed on a part of the display area Ha where the second image effect is displayed, thereby associating the second image effect with the operation of the operation button BT1. Can be emphasized.

  (15) Since the image displayed in the second image effect when the operation button BT1 is operated is changed in the display area Ha, the effect that the association between the second image effect and the operation of the operation button BT1 is easy to understand. Can be realized.

(16) By enclosing the display area Ha on which the second image effect is displayed with the boundary portion K, it is possible to more clearly represent the portion to be noted.
(17) Since the second image effect is started in a state where the display area Ha is stationary, the visibility of the images (effect image M2 and notification image HG) displayed in the display area Ha can be improved. . That is, if the display area Ha created by the boundary K moves around in the image display unit GH, it is difficult to understand what the second image effect is, which leads to a decrease in visibility. For this reason, the meaning of the second image effect can be transmitted to the player by starting the second image effect while the display area Ha is stationary.

  (18) In the second image effect, the area size of the display area Ha is fixed while the second image effect is being executed. When the area size changes, the visible area changes, leading to a decrease in the visibility of the images (effect image M2 and notification image HG) displayed in the display area Ha. For this reason, the fall of visibility can be suppressed by fixing the area size of the display area Ha while the second image effect is being executed.

  (19) By determining the degree of big hit expectation for the second image effect, the player's attention can be gathered for the development of the second image effect, and the interest can be improved. In addition, since the big hit expectation can be obtained by operating the operation button BT1, it is possible to promote the active operation of the operation button BT1.

  (20) The display of the special image can be emphasized by displaying the third image effect in which the special image is displayed in a part of the display area Ha of the image display unit GH created by the boundary K. Therefore, in addition to the development of the background image and the design variation game displayed on the image display unit GH, it is possible to attract the player's attention to another image that suddenly appears in a part of the background image HK, and to improve the interest Can be achieved.

  (21) Then, using the display area Ha created by the boundary portion K and the display areas H of the other image display portions GH, the changes of the images displayed in these display areas are associated with each other. In this way, an interesting production can be realized.

(22) By enclosing the display area Ha on which a special image is displayed with a boundary portion, it is possible to more clearly represent a portion to be noted.
(23) By determining the degree of big hit expectation for the third image effect, it is possible to attract the player's attention about the change in the image, and to improve the interest.

  (24) Since the third image effect starts with the display area Ha being stationary, the visibility of the image (effect image M3) displayed in the display area Ha can be improved. That is, if the display area Ha created by the boundary K moves around in the image display part GH, it is difficult to understand the change of the image, leading to a decrease in visibility. Therefore, by starting the change to the special image in a state where the display area Ha is stationary, it is possible to convey the meaning of the change of the special image to the player.

  (25) In the third image effect, the display area Ha has a fixed area size while the third image effect is being executed. When the area size changes, the visible area changes, leading to a decrease in the visibility of the image displayed in the display area Ha. For this reason, it is possible to suppress a reduction in visibility by fixing the area size of the display area Ha while the special image is displayed.

In addition, you may change the said embodiment as follows.
In the first to third image effects, instead of or in addition to the jackpot expectation degree, an expectation degree that causes a probability variation state may be determined. According to this configuration, it is possible to attract the player's attention as to what image is displayed, and it is possible to improve the interest.

  In the first to third image effects, instead of or in addition to the jackpot expectation degree, an expectation degree that the opening manner of the big winning opening 14 becomes an advantageous opening manner may be determined. Whether it is an advantageous opening mode can be specified by the number of round games and the opening time of the special winning opening 14. For example, assuming that the time of one round game is the same time, a big hit with 15 round games and a big hit with 2 round games are advantageous in that the big hit with 15 round games is advantageous. is there. Also, even if the number of round games is the same, if a long open pattern and a short open pattern with a shorter open time than the long open pattern are provided as open patterns, a big hit with a long total open time is advantageous. It is an open mode.

  When the boundary portion K appears, the color of the boundary portion K (the contour portion of the decorative pattern in the embodiment) may be changed according to a predetermined expectation. For example, the color may be changed so as to notify the level of expectation of jackpot. Further, the color may be changed so as to notify the level of expectation that will be in the probability fluctuation state. Further, the color may be changed so as to notify the level of expectation that the opening mode of the special winning opening 14 becomes an advantageous opening mode. A plurality of types of boundary portions K can be obtained by such color change. In this example, when the color of the boundary portion K is changed in accordance with a predetermined expectation, the expectation indicated by the color may be any of the above-described expectation, or a plurality of expectation degrees arbitrarily combined. It is good. For example, when the color is rainbow, the rainbow color may indicate 100% as the jackpot expectation and may indicate 100% as the expectation to be in a probability variation state. In addition, when a plurality of colors are provided, a color indicating only one of the above-described expectations (for example, the jackpot expectation) and a plurality of expectations (for example, a jackpot expectation) arbitrarily combining the above expectations. The color indicating the degree of expectation that will be in the probability variation state) may be mixed. Further, the boundary portion K is not limited to a change in color, but may be accompanied by a change in a pattern, a shape, or the like, and the change may indicate the degree of expectation similarly to the color described above.

  -The timing at which the boundary K appears may be changed. For example, at the time of reach formation, the display area Ha may be formed with the reach formation symbol only as an outline portion, and an image effect may be executed in the display area Ha. In this case, if the jackpot expectation is set for each type of decorative symbol as in the embodiment, the player can be notified of the expectation of the image effect and the expectation based on the reach formation symbol.

  As shown in FIGS. 8A to 8C, the decorative symbols are stopped and displayed in the order of stoppage of the change, and each time the stop display is performed, the decorative symbols that are stopped and displayed are displayed on the display area Ha as only the outline portion. May be. Then, when three rows of decorative symbols are stopped and displayed, the images of the display areas Ha of the decorative symbols may be connected. That is, the boundary portion K may not appear all at once, but may gradually appear as time passes. Further, the image effect may be executed in the display area Ha created by one boundary portion K.

  In the case where the plurality of display areas Ha are formed by the plurality of boundary portions K, the effect images M1 displayed in the respective display areas Ha may be different from each other. That is, the images may not be connected.

  When the decorative design is Arabic numerals as in the embodiment, the type of numbers in each column may be changed. Further, the decorative design may be a design simulating a kanji or alphabet or a design simulating a living thing (human, animal, plant, fish, etc.) instead of a design simulating Arabic numerals. That is, the design of the decorative design can be arbitrarily changed as long as it is possible to distinguish the type when only the contour portion is used. Note that the decorative symbols in each row may be a mixture of, for example, a symbol imitating Arabic numerals and a symbol imitating Kanji.

  The first to third image effects can be arbitrarily applied as effects associated with the decorative symbol variation game. For example, the present invention may be applied to a reach notice that informs whether or not a reach is formed, and a advance notice that informs whether or not a reach effect develops to a content with a high expectation level of a big hit (so-called super reach). Further, for example, the present invention may be applied to a pseudo continuous effect (so-called pseudo ream), a prefetch effect (so-called continuous effect), and a re-lottery effect. The pseudo-continuous effect is an effect that involves a plurality of variations in a single symbol variation game. The greater the number of variations, the greater the expectation of jackpot. In addition, the pre-reading effect is based on the start suspension determined as the determination target based on the determination result based on the determination result based on the determination result based on the determination result based on the determination result based on the determination result. This is an effect to start a notice before the game starts. The pre-reading effect includes an effect that is executed across multiple games. The re-lottery effect is an effect for deriving whether or not it is a probable big hit. When applied to a pseudo-continuous effect or a pre-read effect, it can be used as an effect for notifying whether to move to the next change. When applied to the re-drawing effect, it can be used as an effect for notifying the expected degree of probability variation, that is, the probability variation state.

  The first to third image effects may appear in a single decorative symbol design variation game, or a combination that cannot appear in the same decorative symbol variation game may be set. For example, the first image effect and the second image effect are allowed to appear in the same symbol design game, and the first image effect and the third image effect appear in the same symbol design game. Doing (or regulating) is prohibited.

  The first to third image effects may be effects that can appear in the corresponding effect mode. For example, a first image effect may appear in the first effect mode, a second image effect may appear in the second effect mode, and a third image effect may appear in the second effect mode. Two image effects may appear in one effect mode.

  -The 1st-3rd image production may set the production which can appear for every game state. The gaming state includes a non-probability variation state and a non-entrance rate improvement state, a probability variation state, and an entrance rate improvement state. That is, the gaming state is composed of a combination of the presence / absence of the probability variation state and the presence / absence of the entrance rate improvement state.

  The first to third image effects may be effects that appear in one symbol variation game (predetermined symbol variation game). The first to third image effects may be effects that appear, for example, in a plurality of consecutive symbol variation games (predetermined symbol variation game).

The first to third image effects may be effects that do not define a predetermined degree of expectation. In other words, it may be a lively effect that enlivens a decorative symbol variation game.
In the second image effect, a plurality of types of character images may be provided. Then, a predetermined expectation such as the jackpot expectation as described above may be set for the character type. Further, a plurality of types of notification images HG may be provided. Then, a predetermined expectation degree such as the big hit expectation degree as described above may be set for the type of the notification image HG.

In the third image effect, a plurality of types of special images may be provided. Then, a predetermined expectation such as the jackpot expectation as described above may be set for the type of special image.
The boundary with the background image HK can be created by the appearance of a part having a contour part and the presence of a part of the display area Ha of the image display unit GH in the part surrounded by the contour part. For example, it may appear when a specific condition is satisfied, and the appearing part may constitute the boundary portion K. For example, the decorative symbol may include a special symbol that does not appear in a normal state but appears when a specific condition is satisfied, and the boundary portion K may be configured by the contour portion of the special symbol.

The entire display area Ha of the image display part GH created by the boundary part K may not be surrounded by the boundary part K.
In the image display part GH, after the change of the image displayed in the display area H of the image display part GH before the appearance of the boundary part K, in the partial display area Ha of the image display part GH created by the boundary part K A change in an image on which a special image that is distinguished from the background image HK is displayed may be generated. Then, the effect may be advanced by the change of the image.
