The second starting opening 13 can enter the game ball by opening the open / close blade (normal electric combination) 15 when the predetermined condition is established (when the normal symbol is won), or It is open for easy access. On the other hand, the second starting opening 13 is closed so that the game ball can not be entered or is difficult to enter when the open / close blade 15 performs a closing operation. The open / close blade 15 operates by receiving power from an actuator (such as a solenoid or a motor). The actuator for operating the open / close blade 15 in this embodiment is a common electric part solenoid SOL1 shown in FIG. Further, a ball passage (not shown) for guiding the entered game ball to the back side of the game board YB is connected in series to the second start hole 13, and the game ball entered in the second start hole 13 is placed in the ball passage. A sensor (starting sensor SE2 shown in FIG. 3) for detecting is provided.

  The special winning opening 14 is a winning opening that allows the game ball to enter when the payout conditions for winning balls are satisfied. 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 the game ball can be entered by the opening of 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 game ball can not be entered by the closing of the special winning opening door 16. The special winning opening door 16 operates by receiving power from an actuator (such as a solenoid or a motor). The actuator for operating the special winning opening door 16 in this embodiment is a special winning solenoid SOL2 shown in FIG. Further, a ball passage (not shown) for guiding the entered game ball to the back side of the game board YB is connected in series in the big winning opening 14, and detects the game ball entering the big winning opening 14 in the ball passage. A sensor (count sensor SE3 shown in FIG. 3) is provided.

  In the big hit game, a round game allowing game balls to enter the big winning opening 14 is played a plurality of times with the predetermined number of predetermined rounds as the upper limit. In one round game, the special winning opening door 16 is opened in a predetermined opening manner. One round game is ended by the end condition of the round game being 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 balls for which the end condition of the round game is satisfied is “8 balls”, and the elapsed time of the round game for which the end condition of the round game is satisfied is “25 seconds”.

  In addition, when a big hit game is produced, an opening time is set before the first round game starts, and during the opening time, an opening effect indicating the start of the big hit game is performed. Further, 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, the game board YB is provided with an operation gate 17. In this embodiment, the operation gate 17 is located to the left of the effect display device 11. The operation gate 17 is always opened with a gate opening 17a opened so as to allow the game ball to enter. In the gate opening 17a, a sensor (gate sensor GS shown in FIG. 3) for detecting a game ball entering and passing is disposed. The gate opening 17a of the operation gate 17 is an entrance for letting the game ball enter when establishing the starting condition of the normal symbol variation game using the normal symbol. The opening and closing blade 15 of the second starting opening 13 wins the winning lottery of the normal symbol performed by the game ball entering the operation gate 17, and after the normal symbol is hit in the normal symbol variation game, Operate from the closed state to the open state.

  Further, on the game board YB, special symbol display devices 18a and 18b, hold display devices 19a and 19b, and a normal symbol display device 20 shown in FIG. 3 are disposed. These display devices are located at a portion of the game board YB that can be viewed by the player when the pachinko gaming machine is viewed from the front. For example, these display devices are disposed on a decoration member disposed in the game area of the game board YB, a corner decoration member of the game board YB, or the like.

  The special symbol display devices 18a and 18b play a symbol variation game using a special symbol, and a special symbol according to the lottery result of the big hit lottery in the symbol variation game is derived. Then, when the game ball enters the first starting opening 12 and is detected, the start condition of the symbol variation game using the first special symbol is satisfied with the ball entering. On the other hand, when the game ball enters the second start opening 13 and is detected, the start condition of the symbol variation game using the second special symbol is satisfied with the entrance of the ball. In the first special symbol and the second special symbol, a big hit lottery is performed triggered by the establishment of the start condition, but 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 in the case of winning the jackpot lottery and the determination ratio of jackpots of the same type are made different. Thereby, in the first special symbol and the second special symbol, the degree of advantage when winning the big hit lottery (for example, the degree of the award ball, the provision period of the ball entry rate improvement state, etc.) is made different.

  In addition, when the starting condition is satisfied, the special symbol display game of the special symbol is performed by the special symbol display devices 18a and 18b to derive the lottery result of the big hit lottery, and the special symbol derived in the symbol change game The symbol variation game which derives the result according to is performed also in the effect display device 11 using a decorative symbol.

  In this embodiment, each of the special symbol display devices 18a and 18b is a 7-segment display device. In the special symbol pattern variation game, a combination of light emitters constituting a 7-segment type display device is derived as a special symbol. The special symbols include a big hit symbol derived when winning a big hit lottery and an out symbol derived when not winning a big hit lottery. On the other hand, in a symbol variation game using a decorative symbol, a combination of decorative symbols in a plurality of rows is derived. The decorative design is configured of, for example, a design that imitates Arabic numerals. Then, a combination in which the decorative symbols in all the rows become the same decorative symbol is the combination of the big hit that can be identified as a big hit lottery, and a combination in which the decorative symbols in all the rows do not become the same decorative symbol is won in the big hit lottery It is considered as a combination of identifiable outliers.

  The result derived in the symbol variation game of the decorative symbol corresponds to the result derived in the symbol variation game of the special symbol. Therefore, in the symbol variation game of the special symbol, the lottery result of the big hit lottery is derived by the special symbol, while the information capable of specifying the lottery result of the big hit lottery is also derived by the ornament symbol in the symbol variation game of the decorative symbol.

  The hold display devices 19a and 19b display the number (starting hold number) of the symbol variation game of the special symbol whose execution is being held. The normal symbol display device 20 performs an ordinary symbol variation game using an ordinary symbol, and in the ordinary symbol variation game, an ordinary symbol according to the lottery result of the lottery of the ordinary symbol is derived in the ordinary symbol fluctuation game.

  Further, as shown in FIG. 1, the pachinko gaming machine 10 is provided with an operation button BT1 as an operation means operable by the player. In this embodiment, the operation button BT1 is disposed on the upper surface of the storage tray 21 that stores gaming 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 portion where the player performs a pressing operation.

FIG. 2 illustrates a decorative symbol used in a symbol variation game of decorative symbol.
In this embodiment, the symbol variation game of decorative symbols derives a combination of three rows of decorative symbols consisting of the left row ZL, the middle row ZC, and the right row ZR. The decorative pattern in each row is configured with a design that imitates the Arabic numerals in [1] to [8]. That is, there are eight decorative patterns that can derive combinations of decorative patterns in each row.

  Each decorative pattern imitating the Arabic numerals of [1] to [8] is configured to distinguish and identify Arabic numerals from the outline. The outline is a line that forms the outline of an object, but, for example, Arabic numerals [6], [8], etc. are added to the outline, and a circular internal line is also necessary to form a number. For this reason, the outline includes an outline and an inner shape line. In addition, a predetermined pattern is applied to each of the decorative patterns in a predetermined color. In this embodiment, among the odd symbols of [1], [3], [5], and [7], the same pattern is applied to [1] and [5] with the same color, and [3] The same pattern is given in the same color in [7]. And the patterns and colors of [1] and [5] are different from the patterns and colors of [3] and [7]. The same pattern is applied in the same color to the even symbols of [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].

  As a result, the decorative pattern of this embodiment can recognize the numbers indicated by each decorative pattern by the outline and can distinguish the numbers. In addition, the decorative design of this embodiment can recognize the grouping of the design from the identity of the pattern and the color, that is, the relevancy of the decorative design imitating different numbers. Specifically, the eight decorative patterns of this embodiment are the first odd group of [1] and [5], the second odd group of [3] and [7], [2] and [7]. 4] and even groups of [6] and [8] can be recognized.

  In this embodiment, the decorative symbol group is a group representing the level of the jackpot expectation. In the symbol variation game of the decorative symbol, the reach is formed by deriving the same decorative symbol in a predetermined plurality of rows (two rows of the left row ZL and the right row ZR in this embodiment), and the remaining rows (this execution In the form, a reach effect for leading one middle row ZC) is performed. Then, the group representing the level of the big hit expectation degree by the decorative pattern described above can make the player recognize the high or low level of the big hit expectation degree when it is derived as the reach formation pattern. In this embodiment, the decorative pattern belonging to the second odd-numbered group is the decorative pattern having the highest hit probability and the decorative pattern belonging to the first odd-numbered group is the decorative pattern having the high hit probability compared to the even group. It is done. In the above three groups, the decorative symbols belonging to the second odd number group may be positioned in such a way that it is determined that the probability fluctuation state described later is to be given when it is a big hit in addition to the highest hit expectation. .

  Returning to the explanation of the pachinko gaming machine 10, the pachinko gaming machine 10 of this embodiment has a probability variation function. The probability fluctuation function is a function capable of giving a probability fluctuation state in which the jackpot probability of jackpot is fluctuated from low probability (normal probability) to high probability after the jackpot game is over. The probability fluctuation state is given, for example, until the next time a jackpot lottery is won. The probability fluctuation state is a gaming state that is more advantageous to the player, because it is easier to win the jackpot lottery than the non-probability fluctuation state in which the probability of winning the jackpot lottery is low.

  Moreover, the pachinko gaming machine 10 of this embodiment is provided with a ball entry rate improving function. The ball filling rate improving function is a function capable of providing a ball filling rate improving state in which the ball filling rate of gaming balls per unit time to the second starting opening 13 is improved. The ball entry rate improvement state is the so-called "power support state" and "high base state". In addition, in the following description, the state to which the ball-incident rate improvement state is not provided may be shown as a "non-ball-filling rate improvement state". The non-entering rate improvement state is the so-called "non-electric support state" and "low base state".

  The ball entry rate improvement state can be realized, for example, by executing one control arbitrarily selected from the following four controls, or by combining and executing a plurality of controls. The first control is a normal symbol variation time reduction control in which the variation time of the normal symbol variation game is made shorter than in the non-entering rate improvement state. The second control is probability fluctuation control of a regular symbol that changes the probability of winning a regular symbol winning lottery (normal hit probability) to a higher probability than in the non-incident rate improvement state. The third control is an open time extension control in which the total open time of the open / close blades 15 based on winning of the normal symbol winning lottery is made longer than that in the non-entering rate improving state. In addition, as the open time extension control, control to increase the number of times of opening and closing of the opening and closing blade 15 based on winning the lottery of the normal symbol more than in the non ball entering rate improving state, and winning the lottery of the ordinary symbol It is preferable to execute at least one control of the control for making the one open time of the open / close blade 15 longer than that in the non-entering rate improvement state based on the above. The fourth control is a special symbol variation time reduction control that makes the variation time (for example, the average variation time) of the special symbol variation game shorter than in the non-entering rate improving state. When the fluctuation time reduction control of the special symbol is executed, the ball entry rate improvement state is a so-called "variation time reduction state".

  The pitch increase state is, for example, the next time until the jackpot lottery is won, or until the symbol change game of the special symbol of the specified upper limit number of times (for example, 100 times) is executed after the pitch increase state is given. Or, it is granted until the jackpot lottery is won 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 prescribed upper limit 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.

In addition, various substrates including the main control substrate 30 and the sub control substrate 31 shown in FIG. 3 are mounted on the pachinko gaming machine 10.
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 storing control information such as a control program of the main control CPU 30a, and writing of necessary data And a main control RAM 30c capable of reading. Further, the main control board 30 has a random number generation circuit 30d.

  Detection signals of the various sensors SE1, SE2, CS, and GS are input to the main control CPU 30a. Further, the main control CPU 30a controls the display contents of various display devices (special symbol display devices 18a, 18b, hold display devices 19a, 19b, normal symbol display device 20, etc.), and various actuators (general motor combination solenoids) Control the operation of SOL1 and the big winning solenoid SOL2).

  The control information stored in the main control ROM 30b includes a main control program for executing processing relating to a game, information specifying a variation pattern (main variation pattern) of a special symbol, various determination values, and the like. The main variation pattern is capable of specifying a variation time (rendering time) during a period when the special symbol starts to be decided after the special symbol starts to be varied. The main variation pattern can be classified into a variation pattern for the big hit variation and a variation pattern for the outlying variation. The jackpot fluctuation is an effect performed when the jackpot lottery is won, and in the symbol fluctuation game of the special symbol, the jackpot symbol is finally derived. The outlier fluctuation is an effect performed when the player does not win the jackpot lottery, and in the symbol fluctuation game of the special symbol, the outlier symbol is finally derived. Note that the out-of-out fluctuation includes a fluctuation that is performed when reach effect is performed in a symbol fluctuation game of a decorative symbol, and a fluctuation that is not performed when reach effect is performed in the symbol fluctuation game of the decorative symbol. In addition, the various determination values include a big hit determination value used for a big hit lottery, a normal hit determination value used for a normal symbol lottery, and the like. The main control RAM 30c also stores various information (random number value, timer value, flag, start pending number, etc.) that can be appropriately rewritten during operation of the pachinko gaming machine 10.

  The main control CPU 30a updates the values of various software random numbers every predetermined control cycle (interrupt cycle), and executes random number update processing (software random number generation processing) stored in the main control RAM 30c. The software random numbers include a jackpot symbol random number used when determining a jackpot symbol of a special symbol, a fluctuation pattern distribution random number used when distributing a main fluctuation pattern, and the like. The random number generation circuit 30 d generates a hardware random number by updating the value by 1 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 big hit lottery of a special symbol or a normal hit random number used for a hit lottery of a normal symbol.

  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 in one direction from the main control board 30. The sub control board 31 can execute the control operation in a predetermined procedure, the sub control ROM 31b storing the control program of the sub control CPU 31a, and the sub capable of writing and reading 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 a symbol variation game of a special symbol, the main control CPU 30a sub-controls information instructing start of variation (game start) in addition to control of display contents of the special symbol display devices 18a and 18b. It transmits to CPU31a. The sub control CPU 31a that has received the information controls the display content so as to cause the effect display device 11 to play the symbol variation game of the decorative symbol. In addition, the sub control CPU 31a performs 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 change game with the start of the symbol change game of the decorative symbol. Control.

  In addition, a detection signal of the operation button BT1 is input to the sub control board 31. The operation button BT1 incorporates 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 makes it possible to identify the operation. The detection unit K1 is, for example, a proximity sensor or a contact switch capable of outputting an electric signal, and constitutes a detection unit. The detection signal is a binary signal consisting of ON / OFF.

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

First, special symbol input processing will be described.
The main control CPU 30a determines whether the gaming ball has entered the first starting opening 12 or the second starting opening 13. In this determination, the main control CPU 30a determines that the gaming ball has entered the first start opening 12 by inputting the detection signal from the first start sensor SE1, and detects the detection signal from the second start sensor SE2. It is determined that the game ball has entered the second starting opening 13 by inputting.

  When the gaming ball enters the first starting opening 12, the main control CPU 30a determines whether the number of start pending reservations of the first special symbol is less than the upper limit number (4 in this embodiment). And, when the start pending number of the first special symbol is less than the upper limit number, the main control CPU 30a adds 1 to the start pending number and rewrites it, and displays the start pending number after addition to be displayed 19a Control. Further, when the game ball enters the second starting opening 13, the main control CPU 30a determines whether the number of start pending reservations of the second special symbol is less than the upper limit number (4 in this embodiment). Then, when the start pending number of the second special symbol is less than the upper limit number, the main control CPU 30a adds 1 to the start pending number and rewrites it, and also displays the start pending number after addition to be displayed 19b Control. When the number of pending start has reached the upper limit number, the main control CPU 30a ends the special symbol input process without adding the number of pending start. Further, when the start pending number is added, the main control CPU 30 a outputs information (such as a hold designation command) that can specify the start pending number after addition to the sub control board 31. The sub control CPU 31a that has input information that can specify the start pending number causes the image display unit GH to display an image indicating the start pending number that can be identified from the information.

  In addition, when the game ball enters the ball by less than the upper limit number of the start pending number, the main control CPU 30a can acquire the values of various random numbers triggered by the ball entry and can specify the acquired values of various random numbers. The random number information is stored in the main control RAM 30c. The random number information may be configured by the value of the random number, or may be configured by information obtained by converting the value of the random number into other information that can specify the value. Further, when storing the random number information, the main control CPU 30a enters the ball entry sequence (information storage sequence) of the gaming ball that triggered the acquisition of the value of the random number and the ball entry sequence of the game ball entered earlier. The main control RAM 30 c is stored so that (information storage order) can be specified. In this process, the main control CPU 30a acquires the value of the big hit random number from the random number generation circuit 30d, and obtains the value of the big hit symbol random number and the value of the variation pattern allocation random number from the main control RAM 30 c. Thereafter, the main control CPU 30a ends the special symbol input process.

Next, special symbol start processing will be described.
The main control CPU 30a determines whether the start condition of the symbol variation game of the special symbol is satisfied. In this determination, the main control CPU 30a determines that the start condition is satisfied when the symbol variation game is not in progress and the big hit is not in progress, while the symbol variation game is in progress or the big hit is in progress. In this case, it is determined that the start condition is not satisfied. And main control CPU30a ends special symbol start processing, when start conditions are not satisfied.

  When the start condition is satisfied, the main control CPU 30a reads the start pending number of the second special symbol, and determines whether the read start pending number is greater than 0 (zero). Then, when the start suspension number 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, when the start pending number of the second special symbol is 0 (zero), the main control CPU 30a reads out the start pending number of the first special symbol, and whether the read start pending number read is greater than 0 (zero) Determine Then, when the start pending number 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 does not execute the symbol variation game of the first special symbol and the symbol variation game of the second special symbol at the same time, but with a specification that causes the symbol variation game of the second special symbol to be preferentially executed. is there.

  In addition, when both the start pending number of the first special symbol and the start pending number 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 the standby state using a device such as the effect display device 11, for example, and obtaining a customer gathering effect.

  When starting the symbol variation game of the second special symbol, the main control CPU 30a subtracts 1 from the start pending number of the second special symbol and rewrites it, and the pending display device 19b is displayed to display the start pending number after subtraction. Control. In addition, when the start control pending number is subtracted, the main control CPU 30 a outputs information (such as a hold specification command) that can specify the start support pending number after subtraction to the sub control board 31.

  Next, the main control CPU 30a acquires the first stored random number information among the random number information stored in the main control RAM 30c. Then, the main control CPU 30a compares the value of the big hit random number specified from the acquired random number information with the big hit determination value, and performs a big hit lottery. In the big hit lottery, a big hit is won when the value of the big hit random number and the big hit judgment value match.

  When the jackpot lottery is won, the main control CPU 30a performs a jackpot process. Specifically, the main control CPU 30a determines the big hit symbol of the special symbol based on the value of the big hit symbol random number specified from the acquired random number information. This determined jackpot symbol becomes a fixed stop symbol derived in the symbol variation game of the special symbol. Further, the main control CPU 30a determines a fluctuation pattern for big hit fluctuation based on the value of the fluctuation pattern assignment random number specified from the acquired random number information.

  On the other hand, when the jackpot lottery is not won, the main control CPU 30a performs an outlier process. In the removal process, the main control CPU 30a determines the removal symbol of the special symbol. This determined out-of-design symbol becomes the fixed stop symbol derived in the symbol variation game of the special symbol. Further, the main control CPU 30a determines a fluctuation pattern for outlier fluctuation based on the value of the fluctuation pattern allocation random number specified from the acquired random number information.

  In the losing process, the main control CPU 30a determines a main variation pattern without reach or a main variation pattern with reach from the main variation patterns for losing variation. For this determination, for example, a reach determination may be performed to determine whether reach effect is to 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 fluctuation pattern allocation random numbers are allocated to the classification of the main fluctuation pattern with reach and the classification of the main fluctuation pattern without reach. Then, when it is determined that reach effect is to be performed in reach determination, the fluctuation pattern is determined according to the fluctuation pattern apportionment random number from the main fluctuation patterns with reach, while reach effect is not performed in reach determination If it is determined, the fluctuation pattern is determined according to the fluctuation pattern allocation random number from the main fluctuation patterns without reach. Also, as another method, without performing reach determination, the variation pattern is selected according to the variation pattern distribution random number from the main variation patterns 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, it is determined whether the reach effect is to be performed by determining the main fluctuation pattern. In addition, it is decided by the specification of a pachinko game machine which decision method is adopted.

  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 for the first special symbol. That is, the main control CPU 30a performs a big hit process or an off process based on the result of subtraction of the start reserve number of the first special symbol, the big hit lottery, and the big hit lottery.

  Then, the main control CPU 30a that has performed the big hit process or the release 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 designates a fluctuation pattern and outputs a fluctuation pattern designation command instructing the start of fluctuation. 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. In addition, the main control CPU 30a starts measurement of the fluctuation time of the symbol fluctuation game of the special symbol. Further, the main control CPU 30a outputs a special symbol designation command that designates a special symbol.

  In addition, 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 fluctuation time defined in the designated fluctuation pattern elapses. Alternatively, the display contents of the special symbol display device 18b are controlled. In addition, the main control CPU 30a outputs an all symbol stop command instructing the stop of the fluctuation when the fluctuation time defined in the designated fluctuation pattern has elapsed.

  The main control CPU 30a performs, in addition to the special symbol input process and the special symbol start process described above, a process relating to a big hit game, a process relating to a gaming state, and a process relating to a normal symbol. In the processing related to the big hit game, processing of opening and closing of the big winning opening 14, the counting processing of the game ball which entered the big winning opening 14 and the like on the basis of the detection signal from the count sensor CS. In the processing relating to the gaming state, processing such as providing a probability fluctuation state or an improvement in the ball-filling rate is performed. For example, the gaming state after the big hit game is associated with the type of the big hit symbol determined when winning the big hit lottery. That is, in the pachinko gaming machine 10 of this embodiment, determining the jackpot symbol corresponds to determining the type of the jackpot, and the main control CPU 30a performs 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 will be described based on the effect control program. When the sub-control CPU 31a receives a control command from the main control CPU 30a, the sub-control CPU 31a executes various processes in accordance with the control command.

First, decorative symbol variation processing will be described.
In the decorative symbol variation process, when the sub-control CPU 31a inputs a special symbol designation command, the sub control CPU 31a determines a combination of decorative symbols to be derived in the symbol variation game of the decorative symbol based on the special symbol designated by the special symbol designation command. When the big hit symbol of the special symbol is designated, the sub control CPU 31a determines the combination of the big hit by the decorative symbol. In addition, when the out-of-hand symbol of the special symbol is designated, the sub-control CPU 31a determines the combination of the decorative symbol to be derived in the symbol fluctuation game of the decorative symbol based on the fluctuation pattern designated by the fluctuation pattern designation command. . Specifically, the sub-control CPU 31a determines a combination of disconnection including the reach formation pattern, when the main fluctuation pattern for out-of-reach variation with reach is designated. Further, when the main fluctuation pattern for out-of-reach fluctuation is designated, the sub-control CPU 31a determines a combination of out-of-reach patterns not including the reach formation pattern.

  In the symbol variation game of the decorative symbol, the reach is formed by deriving the same decorative symbol in a predetermined plurality of rows (two rows of the left row ZL and the right row ZR in this embodiment), and the remaining rows (this execution In the form, a reach effect for leading one middle row) is performed. For this reason, the same decorative pattern derived in a predetermined plurality of lines becomes the reach formation pattern, and the combination of the removal including the reach formation pattern is the same decorative pattern in a plurality of predetermined lines, and the remaining lines are a predetermined plurality It becomes the combination which is the decoration design which differs from the decoration design of the line. Further, the combination of the outs not including the reach forming pattern is a pattern different in a predetermined plurality of rows, and the remaining rows are a combination regardless of the matching with the predetermined plural rows of decorative symbols. Incidentally, the jackpot combination of this embodiment is a combination in which the decorative patterns in all the rows become the same decorative pattern. That is, the combination of the big hit also includes the reach formation pattern.

  In addition, when the sub-control CPU 31a inputs a variation pattern specification command, it determines a sub variation pattern for controlling the display content of the effect display device 11 based on the type of main variation pattern that can be identified from the command. . The sub variation pattern can specify the contents of the effect of the symbol variation game of the decorative symbol.

Among the effects of the symbol variation game of the decorative symbol that can be identified from the sub variation pattern, there are effects as described below.
For example, as for the effect content of complete disapproval without reach effect, for example, the variation of the decorative symbol of 3 lines is stopped in a predetermined order (for example, left line → right line → middle line), and finally reach formation pattern There is an effect content that makes it possible to derive a combination of outliers not included. In addition, the effect contents for performing the reach effect include the effect contents for performing the normal reach effect and the effect contents for performing the super reach effect. The normal reach effect is an effect in which the same decorative pattern is derived in a predetermined plurality of lines to form a reach, and then the variation of the remaining lines is stopped to derive the combination of the decorative patterns. The super reach effect is an effect in which the effect is developed after deriving the decorative pattern of the remaining row by the normal reach effect or from the middle of the normal reach effect, and the combination of the decorative symbols is derived by the effect after the development. Super reach production is positioned as a production with a high expectation of big hit compared to normal reach production. The jackpot expectation can be calculated by the ratio of the appearance ratio in the case of big hit to the total appearance ratio obtained by adding the appearance ratio in the case of out-of-pocket and the appearance ratio in the case of big hit. In the case of providing a plurality of types of super reach effects, the degree of jackpot expectation may be different for each type of super reach effect.

  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 symbol variation game of the decorative symbol is displayed with the effect content specified by the sub variation pattern. Then, the sub-control CPU 31a controls the display contents of the effect display device 11 so as to end the symbol variation game of the decorative symbol and to derive the combination of the decorative symbol according to the passage of the fluctuation time specified from the main fluctuation pattern. . In this embodiment, the sub control CPU 31a functions as an effect control means capable of controlling effects including a symbol variation game of a decorative symbol and an effect (a sound output or light emission) accompanying the symbol variation game. In this embodiment, the symbol variation game of the decorative symbol is ended in response to the input of the all symbol stop command, but the variation time specified from the main variation pattern is counted by the control of the sub control CPU 31a, The symbol variation game of the decorative symbol may be ended. That is, the termination of the symbol variation game of the decorative symbol may be controlled without outputting the full symbol stop command from the main control board 30.

In the pachinko gaming machine 10 of this embodiment configured as described above, an image is displayed on the image display unit GH during a symbol variation game of a decorative symbol, and effects can be performed.
FIG. 4 illustrates an effect performed 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 whole area in which the image can be displayed on the liquid crystal display, and at least the visible area 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 a symbol variation game of a decorative symbol, a window image G1 is displayed in the display area H of the image display unit GH triggered by the operation, and a character is displayed in the window image G1. It 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 in the variable display. And such a production | presentation is performed as a kind of the preliminary | backup production | presentation which announces a big hit expectation, for example. 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 in each of the window images G2 and G3, and a character image indicating the contents of the conversation is displayed as if the character of the window image G2 and the character of the window image G3 are in conversation. . The window images G2 and G3 are displayed so as to overlap on the front side of the background image HK displayed on the image display unit GH and the decorative pattern in the variable display. And such a production | presentation is performed as a kind of the preliminary | backup production | presentation which announces a big hit expectation, for example.

  And, the pachinko gaming machine 10 of this embodiment, as the effect using the display area H of the image display unit GH, an effect (hereinafter, "image effect") different from the effects illustrated in FIG. 4 (a), (b) ) Is configured to be executable.

FIGS. 5 (a) to 5 (e) show an example of the image effect performed in this embodiment.
As shown in FIG. 5A, symbol display positions P1, P2 and P3 for stopping and displaying the decorative symbols in the respective rows are defined in the image display section GH. The symbol display position P1 is a position for stopping and displaying the decorative pattern in the left row ZL, the symbol display position P2 is a position for stopping and displaying the decorative symbol in the middle row ZC, and the symbol display position P3 is a position for displaying the decorative symbol in the right row ZR It is a position to stop display. The stop display includes a stop display and a confirmation stop display. The temporary stop display is a display form of the decorative symbol at a stage where the result of the symbol variation game is not determined. On the other hand, the determination stop display is a display form of the decorative symbol at the stage when the result of the symbol variation game is determined. And fluctuation of each line in the design fluctuation game of the decoration design, it is the indicatory feature where plural types of decoration design passes each design display position P1-P3 in order. In this embodiment, as shown in FIG. 2, the decorative symbols in each row are changed in ascending order in the direction of arrow A, and the vertical direction is such that each symbol display position P1 to P3 crosses the vertical direction of the image display section GH. Scroll to the next

  The background image HK is displayed on the image display unit GH. The background image HK is not limited to a still image. For example, in the case of a background image HK imitating the sky, it may be a moving image in which part of the cloud moves with the passage of time. In the drawing, the background image HK is schematically illustrated by a left-down diagonal line. The symbol variation game of the decorative symbol is displayed so as to overlap the front side of the background image HK, and the decorative symbols in each row are stopped and displayed so as to overlap the front side of the background image HK as shown in FIG.

Here, before describing the details of the image effect performed in this embodiment, an outline of the image effect will be described.
In the image effect, a boundary portion K creating a boundary with the background image HK appears in the display region H of the image display portion GH in a symbol variation game of decorative symbols, and a part of the image display portion GH created by the boundary portion K This is performed by displaying another image distinguished from the background image HK in the display area Ha of the image. In this embodiment, the boundary K is constituted by the outline of the decorative pattern, and the portion surrounded by the outline corresponds to the display area Ha of a part of the image display section GH created by the boundary K. In the display area Ha, another image distinguished from the background image HK is displayed. That is, the decorative design of this embodiment forms an area closed by the outline (only the outline or the outline and the internal line), and the closed area corresponds to the display area Ha.

Hereinafter, the image effects illustrated in FIGS. 5 (a) to 5 (e) will be described in detail. In addition, the image effect illustrated to FIG. 5 (a)-(e) is called 1st image effect for convenience of explanation.
FIG. 5 (a) shows a state in which the combination of decorative symbols of [738] is stopped and displayed on the image display section GH. The decorative design when the image rendering is not performed can distinguish numbers by outline as shown in FIG. 2 and is in a state where a predetermined pattern is applied with a predetermined color.

  Then, in the symbol variation game of the decorative symbol to execute the first image effect, when the variation is started, the pattern and the color of each decorative symbol of [738] are lost, and the decorative symbol of only the outline portion is changed. That is, the state in which only the outline portion is left is in the state in which the boundary portion K creating the boundary with the background image HK appears in the display region H of the image display unit GH. In addition, due to the appearance of the boundary portion K, a portion to which the original pattern and color have been applied appears as a display region Ha of a part of the image display unit GH.

  The decorative symbol [738] in each row is in a state in which the type of symbol can be distinguished even if the pattern and the color disappear, because the outline portion remains. Further, in the first image effect, a plurality of boundary portions K appear at one time by making all of the decorative patterns in three rows as only the outline portion.

  Then, in the first image effect, as shown in FIG. 5B, in the display area Ha of each decorative pattern surrounded by the outline portion, an effect image M1 that is distinguished from the background image HK (the lower left diagonal line). 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, three display areas Ha formed by the decorative patterns in each row are regarded as a screen, and when the effect image M1 is displayed on the screen, only a portion of the effect image M1 overlapping each display area Ha Is performed in a visible manner. Therefore, different images are displayed in the three display areas Ha, since the effect image M1 is divided and displayed.

  Further, in the first image effect, as shown in FIG. 5C, a change occurs in the effect image M1 displayed in FIG. 5B. This example effect image M1 is an image that imitates a cat. The effect image M1 is changed from the striped cat (FIG. 5 (b)) to a mottled cat (FIG. 5 (c)). That is, due to the change of the effect image M1, in the first image effect, the continuous image is displayed in the display area Ha of each decorative pattern surrounded by the outline portion. The effect of displaying this continuous image is a special effect. The effect image M1 itself may be a still image or a moving image. As in this example, if the effect image M1 is a cat, the cat may be performing some operation in the process of displaying a continuous image. Also, for example, in the effect image M1, a character appears, the character holds the gun, displays the process of shooting the gun, or changes the depiction angle of the airship (for example, front → right side → left side) It may be an image with continuous movement, such as a face).

  Further, when continuous images are displayed in the first image effect, the display area Ha of each decorative symbol is in a state of being stationary as shown in FIGS. 5 (b) and 5 (c). The stationary state referred to here is a state in which the decorative pattern is displayed temporarily. The temporary stop display also includes, for example, a so-called fluctuation state in which the decorative pattern is moved up and down or to the left and right. Further, when continuous images are displayed in the first image effect, the area size of the display area Ha of each decorative symbol is fixed as shown in FIGS. 5 (b) and 5 (c). That is, when the effect image M1 is displayed in the first image effect, although the effect image M1 changes, the decorative pattern itself forming the display area Ha does not change and is constant.

  Then, after the first image effect exemplified as described above, in the image display unit GH, the variation of the decorative symbol in each row starts. In the pachinko gaming machine 10 of this embodiment, as shown in FIG. 5 (d), the decorative pattern of each row is temporarily placed in the opposite direction to the fluctuation direction (the direction indicated by the white arrow in FIG. 5 (e)). After moving the fixed amount, the decoration pattern is changed in the changing direction.

  As shown in FIG. 5 (d), when the decorative pattern in each row moves in the direction opposite to the fluctuation direction, the effect image M1 is displayed in accordance with the movement of the outline portion (boundary portion K) of the decorative symbol in each row Each display area Ha also moves. At this time, in each display area Ha, the effect image M1 is displayed following the outline portion of the decorative pattern in each row. Specifically, the display position of the effect image M1 is fixed in the display area H of the image display unit GH, and when the outline portion of each row moves, the display position of the effect image M1 overlaps the effect image M1. Deviation occurs. For this reason, in each display area Ha after movement, a portion of the effect image M1 overlapping when shifted is displayed. In addition, when the outline portion of the decorative pattern in each row is moved, a shift is also generated in the boundary portion with the background image HK displayed in the image display portion GH, but the image display portion appeared when moved A background image HK is displayed in the display area H of the GH.

  After that, as shown in FIG. 5 (e), in the image display unit GH, the decorative symbol of each row is changed. Each decorative pattern in change is returned to the original pattern and color. That is, the display area Ha surrounded by the outline portion of the decorative pattern disappears. Then, in the symbol variation game of the decorative symbol, a combination of the decorative symbols according to the lottery result of the big hit lottery is derived. That is, if the jackpot lottery is won, the combination of the jackpot is displayed as a fixed stop. On the other hand, if the jackpot lottery is not won, the combination of the outset is displayed as a fixed stop.

6 (a) to 6 (e) show an example of the image effect performed in this embodiment.
Hereinafter, the image effects illustrated in FIGS. 6A to 6E will be described in detail. In addition, the image effect illustrated to FIG. 6 (a)-(e) is called 2nd image effect for convenience of explanation. Similarly to the first image effect, in the second image effect, a boundary portion K creating a boundary with the background image HK appears in the display region H of the image display portion GH in the symbol variation game of decorative symbols, and the boundary portion K This is performed by displaying another image distinguished from the background image HK in a partial display area Ha of the image display unit GH created by Therefore, in the description of the second image effect, the description overlapping with the first image effect will be omitted or simplified.

  FIG. 6A shows a state in which the variation of each row is performed by the start of the symbol variation game of the decorative symbol. FIG. 6B shows a state in which the combination of the decorative symbols of [738] is stopped and displayed on the image display unit GH due to the stop of the fluctuation of each column. The decorative design when the image rendering is not performed can distinguish numbers by outline as shown in FIG. 2 and is in a state where a predetermined pattern is applied with a predetermined color.

  Then, in the symbol variation game of the decorative symbol to execute the second image effect, after the combination symbol [738] of the decorative symbol is stopped and displayed as shown in FIG. 6 (b), the pattern of each decorative symbol of [738] There is no color and it changes to the decorative pattern of only the outline part. That is, the boundary K that creates a boundary with the background image HK appears in the display area H of the image display unit GH. The decorative symbol [738] in each row is in a state in which the type of symbol can be distinguished even if the pattern and the color disappear, because the outline portion remains. Further, in the second image effect, a plurality of boundary portions K appear at one time by making all of the decorative patterns in three rows as only the outline portion.

  Then, in the second image effect, as shown in FIG. 6C, in the display area Ha of each decorative pattern surrounded by the outline portion, a special display that is distinguished from the background image HK (the lower left oblique line) An effect image M2 as an effect is displayed. The effect image M2 displays the characters C1, C2 and C3 as a predetermined image for each display area Ha of each decorative pattern, and displays a notification image HG ("PUSH") prompting the user to operate the operation button BT1. Ru. That is, the second image effect in this embodiment is an effect using the operation button BT1 as an operation means operable by the player. Then, a notification image HG prompting the operation of the operation button BT1 is displayed on a part of each display area Ha created by the outline portion of each decorative symbol.

  Then, as shown in FIG. 6D, by operating the operation button BT1, a change occurs in the image of each of the characters C1, C2, and C3 displayed in the display area Ha of each decorative pattern. 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 repulsed by the operation of the operation button BT1.

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

  Thereafter, in the image display unit GH, an effect of fighting with the boss character is displayed. Then, when the jackpot lottery is won, the boss character is won, and the combination of the jackpot is displayed as a fixed stop. On the other hand, when the jackpot lottery has not been won, the boss character is defeated, and the combination of losing is displayed as a fixed stop.

  In the second image effect of this embodiment, an attack can be given to one enemy by one operation of the operation button BT1, and three operations are required to give an attack to all the members. There is. When the three enemies (lower end characters) are repulsed, boss characters appear as shown in FIG. 6 (e) and the effect is continued. On the other hand, if the three enemies can not be repulsed, the combination of [738] derived as shown in FIG.

FIGS. 7 (a) to 7 (e) show an example of the image effect performed in this embodiment.
Hereinafter, the image effects illustrated in FIGS. 7A to 7E will be described in detail. In addition, the image presentation illustrated to FIG. 7 (a)-(e) is called 3rd image presentation for convenience of explanation. Similarly to the first and second image effects, in the third image effect, a boundary portion K creating a boundary with the background image HK appears in the display region H of the image display portion GH in the symbol variation game of decorative symbols This is performed by displaying another image that is distinguished from the background image HK in a partial display area Ha of the image display unit GH created by the boundary K. Therefore, in the description of the third image effect, the description overlapping with the first and second image effects will be omitted or simplified.

  FIG. 7A shows a state in which the variation of each row is performed by the start of the symbol variation game of the decorative symbol. FIG. 7B shows a state in which [7] is stopped and displayed on the image display unit GH because the fluctuation of the left column ZL is stopped. The decorative design when the image rendering is not performed can distinguish numbers by outline as shown in FIG. 2 and is in a state where a predetermined pattern is applied with a predetermined color.

  Then, in the symbol variation game of the decorative symbol to execute the third image effect, as shown in FIG. 7C, the pattern and the color of the decorative symbol [7] disappear and the symbol changes to the decorative symbol of only the outline part. That is, the boundary K that creates a boundary with the background image HK appears in the display area H of the image display unit GH. In addition, the decorative symbol [7] of the left row ZL is in a state in which the type of symbol can be distinguished even if the pattern and the color disappear, because the outline portion remains. In the third image rendition, the decorative design in one row changes to a decorative design with only the outline portion, and the other two rows continue to fluctuate.

  Then, in the third image rendition, as shown in FIG. 7C, in the display area Ha of the decorative design [7] surrounded by the outline portion, the special image is distinguished from the background image HK (the lower left diagonal line). A change occurs in the image on which the effect image M3 as an image is displayed. Specifically, an image imitating the sky is displayed in the display area Ha of the decorative symbol [7], and the image displayed in the display area Ha changes to an image in which a fighter appears. Further, according to the appearance of the fighter, in the display area H of the image display unit GH other than the display area Ha of the decorative symbol [7], the image of the missile launched for striking down the fighter is displayed.

  Thereafter, as shown in FIG. 7 (d), when the fighter is shot down by missiles, the background image HK of the image display unit GH changes to a background image HKa as shown in FIG. 7 (e), and the decorative symbol is displayed. The fluctuation game is continuously advanced. In addition, when the symbol variation game of the decorative symbol continues, the left row starts the variation again. In the third image rendition, when an image change occurs in the display area Ha surrounded by the outline of the decorative pattern (the appearance of a fighter), the image is displayed before the appearance of the boundary K after the change of the image A change also occurs in the image, that is, the background image HK, and the rendering is advanced.

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 out data necessary for the selected image effect from the sub control ROM 31b. The sub control board 31 is provided with a character ROM for storing character image data to be displayed on the image display unit GH, specifically, a person, characters, figures or symbols (including decorative symbols) in advance. Data may be read out. Then, the secondary control CPU 31a outputs the read data to the VDP (video display processor). The VDP performs display control based on the input data, and causes the image display unit GH to display an image.

  In this embodiment, all of the first to third image effects are advance notice effects for giving notice of whether the symbol variation game of the decorative symbol that is attached to the symbol variation game of the special symbol develops in an advantageous manner. An advantageous development in this case is to predict whether it will be a big hit.

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

  The second image rendition is a notice rendition during fluctuation, and is a rendition leading to development after a combination of deviations (opportunity eyes) is derived once. In this embodiment, the jackpot expectation is higher in the case where the presentation is developed. For this reason, the second image effect will notify the degree of expectation of the big hit.

  The sub-control CPU 31a randomly determines 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 in the big hit lottery than when winning in the big hit lottery.

  The third image effect is an advance notice effect during fluctuation, and is an effect leading to a background change using a specific one 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 will notify the degree of expectation of the big hit.

  The sub-control CPU 31a randomly determines whether 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 in the big hit lottery than when winning in the big hit lottery.

Therefore, according to this embodiment, the following effects can be obtained.
(1) A continuous image (effect image M1) distinguished from the background image HK is displayed in a part of the display area Ha of the image display section GH created by the boundary K, thereby displaying the continuous image. It 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 should draw attention to another image (effect image M1) that suddenly appears as part of the background image HK. And can improve the interest.

  (2) By setting the degree of expectation on the continuous image (effect image M1), the player can be focused on what image is displayed, and the interest can be improved.

  (3) By having a plurality of types of boundary portions K, it is possible to cause a change also in the display area Ha created by the boundary portions K. As a result, it is possible to draw the attention of the player as to what kind of boundary K appears, and to improve the interest. In this embodiment, a plurality of boundary portions K are provided due to the difference in the outline of the decorative design.

(4) By surrounding the display area Ha in which the continuous image (effect image M1) is displayed by the boundary portion K, the portion to be focused on can be more clearly represented.
(5) By making a plurality of boundary parts K appear and displaying a continuous image in each display area Ha, it is possible to diversify the part to be made to draw the player's attention and to realize more interesting presentation.

  (6) A part of continuous images (effect image M1) is divided in display area Ha units, so that more attention can be drawn to what kind of image is displayed. That is, the images displayed in the respective display areas Ha can be connected to make it possible to visually recognize the images while imagining the whole image. In addition, by using a plurality of display areas Ha, a large display area of continuous images can be secured, and visibility can be secured.

(7) In addition, since a different continuous image (effect image M1) is displayed for each display area Ha, it is possible to diversify a part to be made to pay the player's attention and to realize more interesting presentation.
(8) By displaying a continuous image on 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 discomfort.

  (9) The first image effect is started in a state where the plurality of display areas Ha are at rest, so that the visibility of the continuous images (effect image M1) displayed in each display area Ha can be improved. it can. That is, when the display area Ha moves around in the image display unit GH, it is difficult to understand what kind of image it is, since it is a particularly continuous image. Therefore, the meaning of the displayed image can be transmitted to the player by starting the first image effect with each display area Ha being stationary.

  (10) The area size of the plurality of display areas Ha in the first image effect is fixed while the continuous image (effect image M1) is displayed. When the area size changes, a change occurs in the visible area, which leads to a decrease in the visibility of the continuous image displayed in the display area Ha. Therefore, by fixing the area size of the display area Ha while the continuous image is displayed, it is possible to suppress the decrease in the visibility of the image.

  (11) The border K is a contour portion of the decorative pattern, and the display area Ha is formed in the portion surrounded by the contour portion. Therefore, while maintaining the original meaning of the decorative symbol, the display area Ha is parallel to the display of the decorative symbol. The first to third image effects can be performed. Then, since the decorative pattern is displayed in a relatively large size in the image display section GH, the display size of the image of the first to third image effects can be secured large according to the size of the decorative pattern, and Visibility can be improved.

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

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

  (14) Associating the second image effect with the operation of the operation button BT1 by displaying the notification image HG prompting the operation of the operation button BT1 in a part of the display area Ha in which the second image effect is displayed Can be emphasized.

  (15) Since the image displayed in the second image effect is changed in the display area Ha when the operation button BT1 is operated, 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 surrounding the display area Ha in which the second image effect is displayed by the boundary portion K, it is possible to more clearly express the portion to be focused on.
(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, notification image HG) displayed in the display area Ha can be improved. . That is, when the display area Ha created by the boundary K moves around in the image display unit GH, it is difficult to understand what effect the second image effect is, leading to a decrease in visibility. Therefore, by starting the second image effect with the display area Ha stationary, it is possible to convey the meaning of the second image effect to the player.

  (18) In the second image effect, the display area Ha has a fixed area size while the second image effect is being performed. When the area size changes, a change occurs in the visible area, which leads to a decrease in the visibility of the images (the effect image M2 and the notification image HG) displayed in the display area Ha. For this reason, the fall of visibility can be suppressed by fixing the field size of display field Ha while the 2nd image rendition is performed.

  (19) By setting the jackpot expectation for the second image effect, the player can be focused on the development of the second image effect, and the interest can be improved. In addition, since it is possible to know the jackpot expectation degree by operating the operation button BT1, it is possible to urge the positive operation of the operation button BT1.

  (20) The display of the special image can be emphasized by displaying the third image effect that causes the special image to be displayed in the partial display area Ha of the image display unit GH created by the boundary portion K. Therefore, in addition to the development of the background image and the symbol variation game displayed on the image display unit GH, the player's attention can be drawn to another image that suddenly appears in a part of the background image HK, and the interest is improved. Can be

  (21) Then, using the display area Ha created by the boundary K and the display area H of the other image display unit GH, the change of the image displayed in these display areas is performed in association with each other. This makes it possible to achieve interesting effects.

(22) By surrounding the display area Ha in which the special image is displayed by the boundary portion, it is possible to more clearly express the portion to be noted.
(23) By setting the jackpot expectation for the third image effect, it is possible to draw the attention of the player to the change of the image, and to improve the interest.

  (24) The third image effect is started when the display area Ha is at rest, so that the visibility of the image (effect image M3) displayed in the display area Ha can be improved. That is, when the display area Ha created by the boundary portion K moves around in the image display unit GH, it is difficult to understand the change in the image, which leads to a decrease in the visibility. Therefore, by starting the change to the special image in the 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 performed. When the area size changes, a change occurs in the visible area, which leads to a decrease in the visibility of the image displayed in the display area Ha. Therefore, by fixing the area size of the display area Ha while the special image is displayed, it is possible to suppress the decrease in the visibility.

The above embodiment may be modified as follows.
In the first to third image effects, the degree of probability may be changed in addition to or instead of the jackpot expectation. According to this configuration, it is possible to draw the attention of the player as to what kind of 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, an expectation may be set such that the opening mode of the large winning opening 14 becomes an advantageous opening mode. It can be specified by the number of round games and the opening time of the big winning opening 14 whether it is an advantageous opening mode. For example, when the time for one round game is the same time, the big hit for playing 15 round games in the opening mode is advantageous for the big hit for playing 15 round games and the big hit for performing 2 round games is there. In addition, even if the number of round games is the same number, in the case of including the long opening pattern and the short opening pattern in which the opening time is shorter than the long opening pattern as the opening pattern, the jackpot having a long total opening time is advantageous. It is an open mode.

  When the boundary K is made to appear, the color of the boundary K (in the embodiment, the outline of the decorative design) may be changed in accordance with a predetermined degree of expectation. For example, the color may be changed so as to notify the high hit of the jackpot expectation. In addition, the color may be changed so as to notify the degree of expectation of becoming a probability fluctuation state. In addition, the color may be changed so as to notify the degree of expectation of the opening mode of the special winning opening 14 becoming the advantageous opening mode. It is also possible to change the kind of boundary K to a plurality of kinds by such color change. In this example, in the case where the color of the boundary K is changed in accordance with the predetermined degree of expectation, the degree of expectation indicated by the color may be any of the above-described degrees of expectation, and a plurality of arbitrarily selected degrees of expectation It may be For example, when the color is iridescent, the iridescent color may indicate 100% as a big hit expectation and 100% as a probability change state. In addition, in the case of providing a plurality of colors, a plurality of expectations (for example, big hit expectation) obtained by arbitrarily combining a color indicating only one of the above expectations (for example, big hit expectation) and the above expectations. It may be mixed with a color indicating the degree of expectation of becoming a probability fluctuation state. Further, the boundary portion K is not limited to a change in color, but may be accompanied by a change in pattern, shape, etc., 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 pattern as the outline portion only, and the image effect may be performed in the display area Ha. In this case, if the big hit expectation is set for each type of decorative symbol as in the embodiment, it is possible to notify the player of the expectation of the image effect and the expectation by the reach formation symbol.

  As shown in FIGS. 8 (a) to 8 (c), the decorative symbols are stopped and displayed in the order of stopping of the change, and an image is displayed in the display area Ha with the decorative symbols stopped being displayed each time it is stopped and displayed. May be Then, when the decorative patterns in three columns are stopped and displayed, the images of the display areas Ha of the decorative patterns may be connected. That is, the boundary K does not have to appear all at once, but may gradually appear as time passes. Also, the image rendering may be performed in the display area Ha created by one border K.

  In the case where a plurality of display areas Ha are formed by a plurality of boundary portions K, the effect images M1 displayed in the respective display areas Ha may be different from one another. That is, the images do not have to be connected.

  -When making a decorative design into an Arabic number like embodiment, you may change the kind of number in each row | line | column.

Further, for example, the present invention may be applied to a pseudo continuous effect (so-called pseudo sequence), a preread effect (so-called continuous effect), and a re-lottery effect. The pseudo continuous effect is an effect that causes a plurality of fluctuations in one symbol fluctuation game, and the jackpot expectation degree is increased as the number of times of fluctuation increases. In addition, the pre-reading effect is determined based on the start suspension with the value of the big hit random number acquired when the game ball enters the starting opening before the big hit lottery, and based on the result of the determination It is an effect to start the notice before the game starts. The preread effect includes an effect to be executed across a plurality of games. The re-lottery effect is an effect that derives whether or not it becomes a probability variation big hit. When applied to the pseudo continuous effect or the pre-read effect, it can be used as an effect for notifying whether to shift to the next fluctuation. When applied to the re-lottery effect, it can be used as an effect of informing the degree of probability variation, that is, the degree of probability variation expected.

  The first to third image effects may be made to appear in a symbol variation game of one decorative symbol, or a combination which can not appear in the symbol variation game of the same decorative symbol may be set. For example, it is permitted that the first image effect and the second image effect appear in the symbol variation game with the same decorative symbol, and the first image effect and the third image effect appear in the symbol variation game with the same decorative symbol Do not do (or regulate).

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

  The first to third image effects may set effects that can appear for each gaming state. The game state includes a non-probability fluctuation state, a non-ball-filling rate improvement state, a probability fluctuation state, and a ball-filling rate improvement state. That is, the gaming state is composed of a combination of the presence or absence of the probability fluctuation state and the presence or absence of the ball entry rate improvement state.

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

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