Abstract

PROBLEM TO BE SOLVED: To increase excitement and enjoyment by changing operation modes of an opening/closing member by changing a normal symbol variation pattern triggered by losing of a game.SOLUTION: A normal symbol variation pattern to be selected when a normal symbol variation game starts is changed according to the kind of losing symbol which can lead to a settlement stop result of a special symbol variation game. For instance, when a losing symbol C appears, the game machine is shifted to a prize winning increase state after the special symbol variation game inducing the losing symbol C is completed. In the prize winning increase state, a normal symbol variation pattern shorter in variation time than a normal state is selected. Thus, during the prize winning increase state, a drawing result of normal symbol winning drawing is quickly induced by reduction in variation time of the normal symbol variation game. Consequently, during the prize winning increase state, the number of opening operation times of an opening/closing blade per unit time increases and an operation mode of the opening/closing blade different from the normal state is achieved.

An effect display device 11 having a liquid crystal display type image display unit GH is disposed at substantially the center of the game board 10 of the pachinko gaming machine. The effect display device 11 includes a symbol variation game that is performed by varying a plurality of symbol sequences (three columns in this embodiment), and various display effects executed in association with the game are displayed as images. In the present embodiment, in the symbol variation game of the effect display device 11, a symbol combination including a plurality of columns (three columns in the present embodiment) is derived. Note that the symbol variation game of the effect display device 11 is performed using decorative symbols (effect symbols) for diversifying display effects. A 7-segment special symbol display device 12 is disposed at the lower left of the effect display device 11. In the special symbol display device 12, a special symbol variation game is displayed in which a plurality of types of special symbols (special symbols) are varied and displayed. The special symbol is a notification symbol indicating the result of the internal lottery (big hit lottery) whether or not the big hit. It should be noted that the symbol variation game of the effect display device 11 and the special symbol variation game of the special symbol display device 12 start simultaneously and end simultaneously.

  The effect display device 11 displays a display result corresponding to the display result of the special symbol display device 12. Specifically, when a big hit symbol (hit display result) that can recognize a big hit is confirmed and stopped on the special symbol display device 12, the big hit symbol (hit display result) is also confirmed and stopped on the effect display device 11. Is displayed. In addition, when a special symbol display device 12 that can recognize a deviation is displayed in a fixed stop state, the special symbol display device 12 is also displayed in a fixed stop manner.

  The jackpot symbol that is confirmed and stopped on the effect display device 11 is composed of symbol combinations in which the decorative symbols in all the rows are the same symbol. In addition, the off-line symbols that are confirmed and displayed on the effect display device 11 are a combination of symbols in which the decorative symbols in all the rows are different, or a decorative symbol in which the decorative symbols in one row are different from the decorative symbols in the other two rows. It is comprised by the following symbol combination. Further, in the effect display device 11, the variation of the symbol sequence stops in the order of left column → right column → middle column as viewed from the player side, and two specific columns (two columns on the left and right in this embodiment). ), When the same decorative design is temporarily displayed (fluctuation fluctuation display), reach is formed.

  A normal symbol display device 13 is arranged on the left side of the special symbol display device 12. In the normal symbol display device 13, a general symbol changing game is performed in which a plurality of types of normal symbols are changed to derive one normal symbol (normal symbol). In the normal symbol display device 13 of this embodiment, a light-emitting body (LED, lamp, etc.) not shown is covered with a lens cover (in FIG. 1, the surface is decorated with “◯ (circle)” and “× (batsu)”). And a plurality of (two in the present embodiment) ordinary symbol display units. In the normal symbol display device 13, an internal lottery (ordinary drawing) of whether or not to hit a universal symbol (whether or not to open the lower start winning opening 15 by the opening operation of the opening and closing blades 16) is performed separately from the big hit lottery of whether or not the big hit The lottery result of (win lottery) is displayed.

  Below the effect display device 11, an upper start winning port 14 having a game ball entrance 14a and a lower start winning port 15 having a game ball entrance 15a are arranged side by side in the vertical direction. The upper start winning opening 14 is configured to always open the entrance 14a so as to allow the entry of game balls at all times. On the other hand, the lower start winning opening 15 is a normal electric accessory, and includes an opening / closing blade 16 as an opening / closing member that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown). The lower start winning opening 15 is in a state in which the entrance is expanded by opening the opening / closing blade 16 so that the game ball can easily enter, while the opening is not expanded by the closing operation of the opening / closing blade 16 to enter the game ball. It is said that it is difficult to ball. An upper start switch SW1 (shown in FIG. 2) for detecting a game ball that has entered the ball is disposed in the back of the upper start winning port 14, and a ball is inserted in the back of the lower start winning port 15. A lower start port switch SW2 (shown in FIG. 2) for detecting a game ball is provided. The upper start winning port 14 and the lower start winning port 15 detect the game balls that have been entered, thereby paying out game balls as a predetermined number of award balls and the starting conditions of a special figure changing game (symbol changing game). Conditions can be granted.

  Below the lower start winning opening 15, a large winning opening (special electric accessory) 18 having a large winning opening door 17 that opens and closes by the operation of an actuator (solenoid, motor, etc.) (not shown) is disposed. . A count switch (not shown) for detecting a game ball that has entered the ball is disposed in the back of the big winning opening 18. The big winning opening 18 can give a payout condition of game balls as a predetermined number of prize balls by detecting the game balls that have entered. The big winning opening 18 is opened by the opening operation of the big winning opening door 17 during the big hit game, thereby allowing a game ball to enter. For this reason, during the big hit game, the player can obtain a chance to win a prize ball.

  A normal symbol operation gate 19 is arranged on the left side of the effect display device 11. A normal symbol variation switch SW3 (shown in FIG. 2) for detecting a game ball that has entered and passed is disposed behind the normal symbol operation gate 19. The normal symbol actuating gate 19 can give only the starting condition of the normal variation game when the game ball passes.

  Further, the pachinko gaming machine according to the present embodiment has a probability variation (hereinafter referred to as “probability variation”) function. The probability variation function is a function for giving a probability variation state (high probability lottery state) in which the lottery probability (winning probability) of the jackpot lottery is changed from a low probability to a high probability after the jackpot game ends. In this embodiment, the probability variation state is given until the next big hit occurs. The probability variation state can be advantageous to the player because the lottery probability of the jackpot lottery fluctuates with high probability and the jackpot is likely to occur. In addition, the state to which the probability variation state is not given becomes the non-probability variation state (low probability lottery state).

  Further, the pachinko gaming machine according to the present embodiment has a function of shortening the variation time (hereinafter referred to as “variation shortening”). The variable function is a function for reducing the variation time of the normal figure variation game and providing a variable state for varying the lottery probability of the normal figure variation game based on the passage of the normal symbol operation gate 19 from a low probability to a high probability. It is. Further, during the variable speed state, the opening time of the opening and closing blades 16 based on the fact that one lottery per lottery is won is longer than in the non-variable speed state. In the present embodiment, the variable state is provided until the probability variation state ends when the lottery probability of the jackpot lottery after the jackpot game ends becomes high (provided probability variation state). On the other hand, in this embodiment, in the variable state, if the lottery probability of the big hit lottery after the big hit game is low (non-assignment of the probability variable state), the symbol variation game of 100 times (the number of variable upper limit) ends. Until then.

Next, the control configuration of the pachinko gaming machine will be described with reference to FIG.
On the back side of the machine, a main control board 30 is mounted as a main control unit for controlling the entire pachinko gaming machine. The main control board 30 executes various processes for controlling the entire pachinko gaming machine and outputs various control commands (control commands) according to the process results. An effect control board 31 as a sub-control unit is mounted on the rear side of the machine. The effect control board 31 controls the operation of various effect devices based on the control command output by the main control board 30.

Hereinafter, specific configurations of the main control board 30 and the effect control board 31 will be described.
The main control board 30 has a main control CPU 30a that executes control operations in a predetermined procedure, a main control ROM 30b that stores a control program for the main control CPU 30a, and a main control CPU that can write and read necessary data. A RAM 30c is provided. Various switches SW1 to SW3 are connected to the main control CPU 30a. Also, a special symbol display device 12 and a normal symbol display device 13 are connected to the main control CPU 30a.

  Also, the main control CPU 30a updates the values of various random numbers such as a jackpot determination random number, a jackpot symbol random number, a reach determination random number, a loss symbol random number, and a universal symbol random number for each predetermined cycle. Update processing (random number generation processing) is executed. The big hit determination random number is a random number used in the big hit lottery (big hit determination). The jackpot symbol random number is a random number used when determining the jackpot symbol of the special symbol when winning in the jackpot lottery. The reach determination random number is a random number used in the reach lottery (reach determination) to determine whether or not to form a reach in the case of not winning the big win in the big win lottery. The random symbol for the off symbol is a random number used when determining the off symbol of the special symbol in the case of not winning in the big hit lottery. The random number for judgment per common figure is a random number used in lottery per common figure. The main control RAM 30c stores (sets) various pieces of information (random numbers, timer values, flags, etc.) that are appropriately rewritten during the operation of the pachinko gaming machine.

  The main control ROM 30b stores a main control program, a plurality of types of special figure fluctuation patterns, and a plurality of types of common figure fluctuation patterns. The special figure variation pattern can specify the variation content (including the variation time) of the symbol variation game related to the special symbol including the special diagram variation game. In addition, the usual pattern variation pattern can specify the variation contents (including the variation time) of the usual diagram variation game. In the present embodiment, the main control ROM 30b serves as storage means.

  The main control ROM 30b stores a big hit determination value. The jackpot determination value is a determination value used in the jackpot lottery and is determined from numerical values (all 400 integers from 0 to 399) that can be taken by the jackpot determination random number. The big hit judgment value is a non-probability change judgment value (low probability big hit judgment value) used in the big hit lottery in the non-probability change state and a probabilistic change judgment value (high probability big hit judgment value) used in the big hit lottery in the probability change state. ) The set number of determination values for probability variation (40 in the present embodiment) is set larger than the set number of determination values for non-probability variation (four in the present embodiment). According to such a setting, the probability of winning in the jackpot lottery in the non-probable change state is 4/400 (= 1/100), while the probability of winning in the jackpot lottery in the probability change state is 400 minutes. 40 (= 1/10).

  The reach control value is stored in the main control ROM 30b. The reach determination value is a determination value used in the reach lottery, and is determined from numerical values that can be taken by the reach determination random numbers (a total of 241 integers from 0 to 240). The reach determination value of the present embodiment is set to the same value in the probability variation state and the non-probability variation state.

  Further, the main control ROM 30b stores a standard hit value. The determination value per common map is a determination value used in a lottery per general map, and is determined from numerical values that can be determined by a random number for determination per general map (a total of 233 integers from 0 to 232). In addition, the determination value per common figure is used in the non-variable determination value (low-probability normal value determination value) used in the lottery per non-variable state and in the lottery per general map in the variable state. There is a judgment value for variable speed (a judgment value per common figure at high probability). The set number of change determination values (232 in this embodiment) is set larger than the set number of non-change determination values (231 in this embodiment). According to such a setting, the probability of winning in the lottery per base drawing in the non-variable state becomes 231/233, while the probability of winning in the lottery per base drawing in the variable state is 232/233. (See FIGS. 3A and 3B).

Next, the effect control board 31 will be described.
The effect control board 31 has an effect control CPU 31a that executes control operations in a predetermined procedure, an effect control ROM 31b that stores a control program for the effect control CPU 31a, and an effect control that can write and read necessary data. A RAM 31c is provided. The effect display device 11 is connected to the effect control CPU 31a. The effect control ROM 31b stores various image data (image data such as symbols, backgrounds, characters, characters, etc.). In addition, various information (timer value, flag, etc.) that is appropriately rewritten during the operation of the pachinko gaming machine is stored (set) in the effect control RAM 31c.

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

First, the special symbol input process will be described.
When the game ball enters the upper start winning opening 14 or the lower start winning opening 15 and receives the detection signals output from the start opening switches SW1 and SW2 that have detected the game balls, the main control CPU 30a receives the main control RAM 30c. Is determined as to whether or not the number of reserved symbols for special symbols stored in is less than the upper limit number (4 in this embodiment). When the determination result of the hold determination is affirmative, the main control CPU 30a adds 1 (+1) to the number of reserved memories for the special symbol, and rewrites the number of reserved memories for the special symbol. Further, the main control CPU 30a having affirmed the hold determination acquires the value of the big hit determination random number and the value of the big hit symbol random number from the main control RAM 30c, and associates the value with the number of reserved memories for the special symbol. The data is stored in a predetermined storage area of the main control RAM 30c. When the determination result of the hold determination is negative, the main control CPU 30a does not rewrite the reserved memory number for the special symbol exceeding the upper limit number, and does not acquire the value of each random number described above.

Next, the special symbol start process will be described.
The main control CPU 30a first determines whether or not a big hit game is being played and whether or not a special figure variation game is being executed. When this determination result is affirmative, the main control CPU 30a ends the special symbol start process.

  On the other hand, when the determination result is negative (not in the special figure variation game and not in the big hit game), the main control CPU 30a reads the number of reserved symbols for special symbols stored in the main control RAM 30c. Then, it is determined whether or not the number of reserved memories is larger than “0 (zero)” (whether or not a starting reserved ball exists). When the number of reserved memories is “0”, the main control CPU 30a ends the special symbol start process. On the other hand, when the reserved memory number is larger than “0”, the main control CPU 30a subtracts 1 from the reserved symbol number for the special symbol, and then the big hit determination random number stored in the predetermined storage area of the main control RAM 30c. Read the value. Then, the main control CPU 30a compares the read jackpot determination random number value with the jackpot determination value, and performs a jackpot lottery (jackpot determination) as to whether or not it is a jackpot. At this time, the main control CPU 30a checks the set value of the gaming state flag stored in the main control RAM 30c. The main control CPU 30a compares the non-probability change determination value with the jackpot determination random number when the gaming state is in a non-probability change state, and the probabilistic change determination value and the jackpot when the gaming state is in a probabilistic change state. Compare random numbers for judgment. In the present embodiment, the main control CPU 30a that performs jackpot lottery (hit determination) serves as the jackpot lottery means.

  When the big hit determination random number value matches the big hit determination value in the big hit lottery, the main control CPU 30a executes the big hit fluctuation process because the big hit is won. In the big hit variation process, the main control CPU 30a determines a big hit symbol as a special symbol to be confirmed and stopped on the special symbol display device 12, and selects and decides a special figure fluctuation pattern for the big hit variation. The jackpot variation is an effect that the symbol variation game is developed so that the jackpot symbol is finally stopped and displayed through the reach effect. The reach effect is an effect that is performed after the reach is formed in the symbol change game with the decorative symbol of the effect display device 11 until the symbol combination (big hit symbol or off symbol) is finally derived. In the special symbol display device 12, when the symbol variation game is started, the symbol variation is continued until the variation time elapses without performing the reach effect.

  When determining the jackpot symbol, the main control CPU 30a determines the jackpot symbol corresponding to the value of the jackpot symbol random number acquired together with the value of the jackpot symbol random number used in the jackpot determination. The jackpot symbol random number of this embodiment can take all 100 integer values from 0 to 99. Further, in this embodiment, as shown in FIG. 3 (a), as a big hit symbol, a big hit symbol A indicating a probability variable big hit that gives a probability variation state after the big hit game ends, and a non-probable change that gives an uncertain change state after the big hit game ends. A big hit symbol B indicating a big hit is set. The jackpot symbols A and B are each assigned 50 jackpot symbol random numbers. In the present embodiment, the type of jackpot, that is, whether it is a probability variation jackpot or a non-probability variation jackpot is determined by determining the jackpot symbol. Therefore, in the present embodiment, the main control CPU 30a that determines the special symbol is a big hit type determination means (probable change) that determines which big hit from a plurality of types of big hits (whether or not to give a probability variation state). Functions as a determining means). In the present embodiment, the big hit symbols A and B are the specific hit symbols.

  On the other hand, if the value of the big hit determination random number and the big hit determination value do not match in the big hit lottery, the main control CPU 30a executes the deviation variation process because the big hit is not won. In the deviation variation process, the main control CPU 30a determines a special symbol variation pattern for the variation variation as well as determining a special symbol as a special symbol to be confirmed and stopped on the special symbol display device 12. The deviation variation is an effect that the symbol variation game is developed so that the symbol is finally stopped and displayed. Note that the deviation variation includes a reach effect and a reach effect. For this reason, in the deviation variation process, the main control CPU 30a acquires the value of the reach determination random number from the main control RAM 30c, and compares the acquired reach determination random number with the reach determination value to perform reach determination. . Then, when the reach determination random number value and the reach determination value match, the main control CPU 30a determines the detachment with reach, and selects and determines the special figure variation pattern for detachment variation including the reach effect. On the other hand, if the value of the reach determination random number and the reach determination value do not match, the main control CPU 30a determines a detachment without reach, and selects and determines a special figure variation pattern for detachment variation that does not include a reach effect. .

  Further, when determining the lost symbol, the main control CPU 30a obtains the value of the random symbol for the symbol for failure from the RAM 30c for main control, and determines the symbol for the error corresponding to the obtained random number for the symbol for failure. The random symbol for outlier design of this embodiment can take all 900 integer values from 0 to 899. In the present embodiment, the main control CPU 30a differs in the types of symbols to be determined in the variable state and in the non-variable state. More specifically, in the non-variable state, an outlier corresponding to the random symbol value for the out symbol is determined from among the out symbols C, D, and E shown in FIG. The missing symbols C and D are each assigned one missing symbol random number value, and the missing symbol E is assigned 898 missing symbol random values. On the other hand, in the variable state, only the off symbol E is determined. The missing symbols E to be determined in the variable state are assigned 900 random symbol values for the missing symbols.

  In the present embodiment, the off-symbols C and D are set as symbols that can trigger entry into a winning increase state, which will be described in detail later. The winning increase state is a state in which the winning rate to the lower start winning opening 15 is increased by improving the operating rate of the opening / closing blade 16 per unit time, and is positioned as a privilege given to the player in the non-variable state. ing. On the other hand, the off symbol E is set as a symbol that maintains the operating state (control state related to the operation) of the opening / closing blade 16 in the current state. The main control CPU 30a determines a shift symbol without considering the determination result of reach determination. For this reason, the presence / absence of the reach effect cannot be distinguished from the determined type of the missing symbol (special symbol).

  The main control CPU 30a, which has determined the special symbol and the special symbol variation pattern in the special symbol start process, outputs the control command generated according to the determined items to the effect control CPU 31a at a predetermined timing. More specifically, the main control CPU 30a first outputs a special figure variation pattern designation command for instructing a special symbol variation pattern and instructing the start of the symbol variation game at the start of the symbol variation game. Further, the main control CPU 30a outputs a special symbol stop symbol designating command for designating a special symbol, and then outputs the special symbol variation pattern designating command. Then, the main control CPU 30a issues a symbol stop command for instructing the end of the symbol variation game (determination of symbol determination) when the variation time determined in the designated special symbol variation pattern has elapsed, as the variation time elapses. Output.

Next, the jackpot game process executed by the main control CPU 30a when the jackpot lottery is won will be described.
In the jackpot game, an opening effect indicating the start of the jackpot game is first performed, and a round game that opens the jackpot 18 after the opening effect ends is performed up to a prescribed number of rounds (15 in this embodiment). After the final round game, an ending effect indicating the end of the jackpot game is performed. One round game ends when either a predetermined round game time (for example, 25 seconds) elapses or a predetermined maximum number of game balls (for example, nine balls) enter. The process ends when the condition is satisfied.

  In the big hit game process, the main control CPU 30a first outputs an opening command for instructing execution of the opening effect to the effect control CPU 31a. Next, the main control CPU 30a controls each round game after the opening effect ends. That is, the main control CPU 30a outputs a round command instructing the start of a round game to the effect control CPU 31a at the start of each round game, and controls the opening and closing of the big prize opening 18. Then, when the final round game is finished, the main control CPU 30a outputs an ending command for instructing execution of the ending effect to the effect control CPU 31a. Thereafter, the main control CPU 30a ends the big hit game when the ending effect ends.

Next, a game state process executed by the main control CPU 30a in order to control the game state after the end of the big hit game will be described.
First, the gaming state process when the jackpot symbol A is determined will be described.

  Since the main control CPU 30a gives the probability variation state and the variation state after the big hit game ends, it sets “1” in each of the probability variation flag and the operation flag as the game state flag. Thereby, the gaming state after the end of the big hit game is set to “high probability + variable” shown in FIG. Further, the main control CPU 30a outputs a probability change command indicating the probability change state and an operation command indicating the change state to the effect control CPU 31a. Then, the main control CPU 30a sets “0” to the probability variation flag and the activation flag, respectively, and produces a non-probability variation command indicating a non-probability variation state and a non-operation command indicating a non-variation state, according to the next big hit. Output to the control CPU 31a. Thereby, the gaming state during the big hit game is set to the non-probability changing state and the non-changing state, that is, “low probability + no change” shown in FIG.

Next, the gaming state process when the jackpot symbol B is determined will be described.
Since the main control CPU 30a gives the non-probability change state and the short change state after the big hit game ends, it sets “0” in the probability change flag and “1” in the operation flag. Thereby, the gaming state after the big hit game is ended is “low probability + variable” shown in FIG. Further, the main control CPU 30a outputs a non-probability change command indicating the non-probability change state and an operation command indicating the change state to the effect control CPU 31a. Further, the main control CPU 30a sets “100 (times)” as the upper limit of the number of times of change indicating the number of operations of the remaining special figure variable game to which the variable state is given, Each time it is executed, the operation count is decremented by -1 (1 subtraction). The main control CPU 30a sets “0” to the operation flag and outputs a non-operation command to the effect control CPU 31a when the special figure variation game for the number of times of operation ends. As a result, the gaming state after the transition from the variable state to the non-variable state is set to “low probability + no variable” shown in FIG. The main control CPU 30a sets the probability variation flag and the operation flag to “0” and outputs a non-probability variation command and a non-operation command when the next big hit occurs during “low probability + variation”, respectively. To do.

  As shown in FIG. 4, the aforementioned winning increase state is given in the non-probable change state (probability change flag “0”) and the non-change state (operation flag “0”), that is, “low probability + no change”. . The gaming state of “low probability + no change” can be taken in the normal state as well as in the winning increase state and the big hit game. The normal state is a state where the winning is not increased and the game is not a big hit game at the time of “low probability + no change”.

  As shown in FIG. 3 (b), the main control CPU 30a has determined that the off symbol C or the off symbol D is determined in the special start process in the non-change state when the big hit lottery is not won. As a trigger, a winning increase state is caused after the end of the special figure variation game for deriving the off symbol. Then, the main control CPU 30a sets a value indicating the gaming state in a non-variable state flag as a gaming state flag for identifying the gaming state in the non-variable state. In the present embodiment, the main control CPU 30a sets “0” in the normal state, sets “1” when the lost symbol C is in the increased winning state, and sets “2” when the lost symbol D is in the increased winning state. . Further, the main control CPU 30a outputs a non-variable state command indicating the gaming state based on the set value of the non-variable state flag to the effect control CPU 31a.

  Then, as shown in FIG. 3 (b), the main control CPU 30a wins a big hit lottery after the occurrence of the increased winning state (determination of the big winning symbol A, B) or triggers the entry of the increased winning state. The winning increase state of the same condition is maintained until a winning symbol that can be a trigger for entering a winning increase state other than the winning symbol is determined. Specifically, the main control CPU 30a maintains the winning increase state based on the losing symbol C until the losing symbol D is determined when the winning symbol C is entered and the winning increase state is generated. In addition, when the winning symbol D is used as a trigger for entering the winning increase state, the main control CPU 30a maintains the winning increasing state based on the slipping symbol D until the losing symbol C is determined.

  On the other hand, the main control CPU 30a maintains the state when the big symbol lottery is not won in the special start process in the non-variable state and the off symbol E is determined. Specifically, the main control CPU 30a maintains the normal state when the shift symbol E is determined in the normal state and maintains the normal state when the shift symbol E is determined during the winning increase state. . That is, the off-line symbol E is a symbol that does not cause a state change.

  In addition, when the winning symbol C is entered and the winning increase state is generated, and when the winning symbol C is determined again during the winning increasing state, the winning symbol C based on the slipping symbol C is newly entered for control purposes. However, it can be said that the state is maintained because the winning increase state of the same condition is generated before and after the entry. This also applies to the case where a winning increase state is triggered by the off symbol D as an entry trigger. In addition, the main control CPU 30a suspends execution of the special figure variation game during the big hit game in which the game state is “low probability + no change”, so that an increase in winnings may occur during the big hit game. Absent. During the big hit game, the game is in a normal state. The winning increase state, the normal state, and the variable state are created as different states by the control related to the normal symbol (ordinary variation game) described below.

Hereinafter, a process executed by the main control CPU 30a for the normal symbol will be described.
The main control CPU 30a executes various processes such as a normal symbol input process and a normal symbol start process based on the main control program. In the present embodiment, the main control CPU 30a executes various processes such as a normal symbol input process and a normal symbol start process every predetermined control period (for example, 4 ms).

First, the normal symbol input process will be described.
When the game ball enters the normal symbol operation gate 19 and receives the detection signal output from the normal symbol variation switch SW3 that has detected the game ball, the main control CPU 30a receives the normal symbol stored in the main control RAM 30c. Whether or not the reserved storage number is less than the upper limit number (4 in this embodiment) is determined. If the determination result of the hold determination is affirmative, the main control CPU 30a adds 1 (+1) to the number of reserved symbols for normal symbols, and rewrites the number of reserved memories for normal symbols. Further, the main control CPU 30a having affirmed the hold determination acquires the random value for determination per universal drawing from the main control RAM 30c, and associates the value with the number of reserved memories for the normal symbol in the main control RAM 30c. Store in a predetermined storage area. When the determination result of the hold determination is negative, the main control CPU 30a does not rewrite the number of reserved symbols for normal symbols exceeding the upper limit number, and does not acquire the value of the random number for determination per common figure.

Next, the normal symbol start process will be described.
First, the main control CPU 30a determines whether or not the opening / closing blade 16 is in operation and whether or not the usual-game variable game is being executed. If this determination result is affirmative, the main control CPU 30a ends the normal symbol start process.

  On the other hand, if the determination result is negative (the game is not in the normal-game variation and the opening / closing blade 16 is not in operation), the main control CPU 30a holds the normal symbol storage stored in the main control RAM 30c. The number is read out, and it is determined whether or not the number of reserved storage is larger than “0 (zero)” (whether or not a start holding ball exists). If the number of reserved memories is “0”, the main control CPU 30a ends the normal symbol start process. On the other hand, if the number of reserved memories is larger than “0”, the main control CPU 30a decrements the number of reserved symbols for normal symbols by 1, and then determines the per-general map stored in a predetermined storage area of the main control RAM 30c. Read a random value. Then, the main control CPU 30a compares the read per-general random number for determination and the per-standard determination value, and performs a per-standard lot determination (determined per normal figure) as to whether or not it is a normal symbol. At this time, the main control CPU 30a checks the set value of the gaming state flag. Then, the main control CPU 30a compares the non-variable determination value with the random number for determining per figure when the gaming state is the non-variable state, and changes when the gaming state is the variable state. Compare the judgment value for short and the random number for judgment per common figure. By selecting the per-map decision value according to the game state, the lottery probability is determined with a high probability in the variable state, while in the variable state, the lottery probability is determined with a different lottery probability. fluctuate. In the present embodiment, the lottery per common drawing is the operation lottery, and the main control CPU 30a is the lottery means.

  If the random value for determining the normal symbol matches the determined value for the normal symbol in the lottery for the normal symbol, the main control CPU 30a executes the winning variation process because it has won the normal symbol. In the winning variation process, the main control CPU 30a determines a winning symbol as a normal symbol to be displayed in a fixed stop on the normal symbol display device 13, and selects and determines a common symbol variation pattern for a normal variation game. On the other hand, in the lottery per common drawing, when the random value for judgment per common drawing and the judgment value per common drawing do not match, the main control CPU 30a does not win the normal symbol, and thus executes a deviation variation process. . In the deviation variation process, the main control CPU 30a determines a deviation symbol as a normal symbol to be displayed in a fixed stop on the normal symbol display device 13, and selects and determines a common symbol variation pattern for a regular variation game.

  When determining the normal variation pattern, the main control CPU 30a selects and determines a general variation pattern according to the gaming state. More specifically, the main control CPU 30a selects and determines the normal fluctuation pattern of the fluctuation time “2 (seconds)” shown in FIG. Further, the main control CPU 30a selects the normal pattern variation pattern of the variation time “6 (seconds)” shown in FIG. 3 (b) in the non-variable state and in the winning increase state based on the off symbol C. ,decide. Further, the main control CPU 30a selects the normal pattern variation pattern of the variation time “40 (seconds)” shown in FIG. 3 (b) in the non-changing state and in the winning increase state based on the off symbol D. ,decide. In the normal state, the main control CPU 30a selects and determines the normal fluctuation pattern of the fluctuation time “270 (seconds)” shown in FIG. In this embodiment, “6 (seconds)” and “40 (seconds)” ordinary map variation patterns become the second ordinary diagram variation pattern that defines the second variation time, and “270 (seconds)” diagram. The variation pattern is the first common pattern variation pattern that defines the first variation time.

  Subsequently, the main control CPU 30a, which has selected the usual figure variation pattern, causes the normal symbol display device 13 to execute the usual figure variation game in accordance with the usual figure variation pattern. The main control CPU 30a causes the normal symbol display device 13 to display the winning symbol on the normal symbol display device 13 if the lottery per common symbol is won when the variation time determined in the normal symbol variation pattern has elapsed. When the winning lottery has not been won, the symbol that has been lost is displayed on the normal symbol display device 13 with a fixed stop. In the present embodiment, the main control CPU 30a serves as control means.

  In this way, when the determination of the base map change pattern and the control time of the base map change game are controlled, the lottery result of the base map lottery is derived after the start of the base map change game. The time until operation varies depending on the gaming state. That is, in the variable speed state, the usual figure fluctuation pattern having the shortest fluctuation time is determined, so that the fluctuation time of the normal figure fluctuation game is shortened compared to the non-variable state, and the opening / closing blade 16 opens. The time until is the shortest. In the non-variable state, the normal state fluctuation pattern is determined in the order of the normal state <the winning increase state based on the off symbol D <the winning increase state based on the off symbol C, and the opening / closing blade The time until 16 opens is shortened.

Next, a winning game process (opening / closing control of the opening / closing blade 16) executed by the main control CPU 30a when the lottery per lot is won will be described.
When the lottery per common symbol is won, the main control CPU 30a opens and closes the open / close blades 16 according to a predetermined operation pattern after the end of the regular symbol variation game (after the symbol symbol stop display). Specifically, as shown in FIG. 3 (a), the main control CPU 30a opens and closes the opening / closing blade 16 in the first open time (1.5 seconds) in the variable speed state (see FIG. 3A). (3 times) for the opening operation. On the other hand, as shown in FIG. 3B, the main control CPU 30a, in the non-variable state, opens and closes the opening / closing blade 16 with a second opening time (1.4 seconds) shorter than the first opening time. The opening operation is performed for the second opening number (three times) which is the same number as the first opening number.

  By controlling the opening operation of the opening / closing blade 16 with different operation patterns according to this gaming state (variable state and non-variable state), the opening time of the opening / closing blade 16 is shorter in the variable state than in the non-variable state. Becomes longer. In other words, during the variable speed state, the number of times the opening and closing blades 16 are opened is the same as that during the non-variable speed state when one lottery is won per common map, but one open time is set longer. As a result, the total opening time becomes longer. For this reason, the variable state can be an advantageous state compared to the non-variable state.

  In addition, during the non-variable state, regardless of the game state (normal state or winning increase state), the operation mode (opening number and opening time) of the opening / closing blade 16 when the lottery per one normal drawing is won is the same. It becomes an operation mode. However, in the present embodiment, during the non-variable state, as shown in FIG. 3B, the variation time of the regular variation game varies due to the difference in the regular variation pattern determined according to the gaming state. For this reason, in the present embodiment, when the fluctuation time becomes short, when the lottery per one normal drawing is won, the opening operation of the opening and closing blades 16 based on the single winning is completed through the normal drawing changing game. Is shortened. Therefore, during the non-change state, the game state in which the normal variation pattern having a short variation time is determined, the number of winning lotteries per unit time per unit time and the number of opening operations of the opening / closing blade 16 increase. As a result, the number of winnings per unit time for the lower start winning opening 15 shows an increasing tendency. More specifically, in the present embodiment, the number of winnings per unit time increases in the order of the normal state <the winning increase state based on the off symbol D <the winning increasing state based on the off symbol C.

  In the present embodiment, the main control CPU 30a functions as an operating means that operates the open / close blade 16 in the open state. When the opening / closing blade 16 is opened from the closed state to the opened state, the main control CPU 30a outputs an opening signal to an actuator (solenoid) that operates the opening / closing blade 16. On the other hand, when closing the open / close blade 16 from the open state to the closed state, the main control CPU 30a outputs an open signal to an actuator (solenoid) that operates the open / close blade 16.

Next, various processes executed by the effect control CPU 31a of the effect control board 31 based on the sub-control program will be described.
When the special control fluctuation pattern designation command is input, the production control CPU 31a selects image display data based on the production contents (variation contents) corresponding to the special figure fluctuation pattern designated by the command. In addition, when the stop control designation command for special symbols is input, the effect control CPU 31a generates a decorative symbol to be confirmed and stopped on the effect display device 11 according to the command. Specifically, the production control CPU 31a generates a jackpot symbol as a decorative symbol when a special symbol is designated as a special symbol, and is disregarded as a decorative symbol when a special symbol is designated as a special symbol. Generate a symbol. At this time, when the special-figure variation pattern including the reach effect is instructed, the effect control CPU 31a generates the off-set symbol including the reach symbol as the decorative symbol. Then, the effect control CPU 31a controls the display contents of the effect display device 11 so as to display an image of the symbol variation game based on the image display data, and generates a symbol stop command when a symbol stop command is input during the symbol variation game. The decorated symbol is displayed on the effect display device 11 in a fixed stop state, and the symbol variation game is terminated.

  In addition, when the control command output during the big hit game such as the opening command, the round command, and the ending command is input, the effect control CPU 31a controls the effect during the big hit game according to these commands. That is, the effect control CPU 31a causes the opening effect, the round effect, and the ending effect to be executed according to the control command described above.

  In addition, when the gaming state is “high probability + changed” by the input of the gaming state command, the effect control CPU 31a displays an image (image GC in FIG. 5) indicating that the state is in the image display unit. An image is displayed on the GH. Further, when the gaming state is “low probability + variable” by the input of the gaming state command, the effect control CPU 31a displays an image (image GB in FIG. 5) indicating that state as the image display unit GH. Display images. In addition, when the game state command is input, the effect control CPU 31a indicates that the game state is “low probability + no change” and is in the normal state (not in the winning increase state). The displayed image (image GA in FIG. 5) is displayed on the image display unit GH. In addition, when the gaming state command is “low probability + no change” and the winning increase state, the effect control CPU 31a indicates that the gaming state is in that state (not in the normal state). The displayed image (image GB ′ in FIG. 5) is displayed on the image display unit GH. In the present embodiment, the image in the normal state and the image with high accuracy / low accuracy + variation are configured with clearly distinguishable images. On the other hand, the image in the winning increase state is composed of images that are very similar to the image with low accuracy + no change, so that the impression that the change state was given without going through the big hit is given. It has become.

Hereinafter, an example of the transition of the gaming state realized by the pachinko gaming machine of the present embodiment will be described with reference to FIG.
When power is turned on to the pachinko gaming machine, the initial gaming state is “low probability + no change” and a normal state. The initial gaming state is created by initializing (RAM clearing) the content stored in the main control RAM 30c in a pachinko gaming machine equipped with a backup function. In this gaming state, the usual figure variation pattern in which the fluctuation time is set to “270 (seconds)” is selected as the usual figure fluctuation pattern of the usual figure fluctuation game based on the lottery per ordinary figure. For this reason, in the normal state, since the fluctuation time of the normal figure fluctuation pattern for deriving the lottery result of the lottery per common figure is the longest, the number of opening operations of the opening and closing blades 16 per unit time is small, and the lower start prize opening The number of balls entering 15 is suppressed. In the normal state, even if winning symbol E is won, the selected normal pattern variation pattern does not change.

  In the normal state, if the winning symbol C is won without winning the big win lottery, after the special symbol variation game for deriving the missing symbol C is ended, the winning increase state is entered. That is, by entering the winning increase state, the main control CPU 30a changes the type of the normal map change pattern selected at the start of the normal map change game based on the lottery result of the normal map lottery. And, by changing the usual figure variation pattern based on winning of the off symbol C, the fluctuation time (6 (seconds)) of the ordinary figure variation pattern for deriving the lottery result of the lottery per ordinary figure is in the normal state while the prize is increasing. Shorter than sometimes. As a result, the number of opening operations of the opening / closing blade 16 per unit time increases. In addition, during a state change triggered by a loss (normal state → winning increase state), the lottery probability of the lottery per regular drawing is maintained unchanged, and the gaming state is also maintained “low probability + no change”. . In addition, in the winning increase state triggered by the off symbol C, even if the off symbol E is won, the selected normal figure variation pattern does not change.

  Also, when the winning symbol C is an opportunity, the winning symbol lottery is not won, but if the winning symbol D is won, the special symbol variable game for deriving the missing symbol D is completed, and a new winning bonus state is reached. Rush into. That is, by entering the winning increase state, the main control CPU 30a changes the type of the normal map change pattern selected at the start of the normal map change game based on the lottery result of the normal map lottery. And, by changing the normal figure fluctuation pattern based on the winning symbol D winning, the fluctuation time (40 (seconds)) of the normal figure fluctuation pattern for deriving the lottery result of the lottery per normal figure is in the normal state during the winning increase state. It is shorter than the time and longer than the winning increase state triggered by the off symbol C. As a result, the number of opening operations of the opening / closing blades 16 per unit time is increased as compared with the normal state, while the opening operation of the opening / closing blades 16 per unit time is performed as compared with the winning increase state triggered by the off symbol C. The number of times decreases. In addition, when the state changes triggered by a loss (the winning increase state triggered by the losing symbol C → the winning increase state triggered by the losing symbol D), the lottery probability of the lottery per regular symbol is maintained unchanged. The game state is also maintained “low probability + no change”. Note that, in the winning increase state triggered by the off symbol D, even if the off symbol E is won, the selected normal figure variation pattern does not change.

  Also, in the state of increasing winnings with the off symbol D as an opportunity, if you win the jackpot lottery and win the jackpot symbol A, after the special figure variation game that derives the jackpot symbol A ends, the jackpot game (low probability + change) (No short). After that, when the big hit game ends, the gaming state shifts to “high accuracy + changeable”, and the main control CPU 30a selects at the start of the normal figure variation game based on the lottery result of the normal figure lottery. The type of variation pattern is changed. And, by changing the general figure fluctuation pattern based on the winning of the big hit symbol A, the fluctuation time (2 (seconds)) of the normal figure fluctuation pattern for deriving the lottery result of the lottery per common figure becomes the shortest during the variable state. . As a result, the number of opening operations of the opening / closing blade 16 per unit time is increased as compared with other gaming states. In addition, when a state change is triggered by a big hit, the lottery probability of the lottery per regular drawing is changed from a low probability to a high probability. In the variable state, even if the winning symbol E is won, the selected normal pattern variation pattern does not change.

  In the case of “high accuracy + variable length”, if the big hit lottery is won and the big hit symbol B is won, after the special figure variation game for deriving the big hit symbol B, the big hit game (low probability + no variable) ) After that, when the big hit game ends, the game state shifts to “low probability + shortage”, and the main control CPU 30a selects at the start of the normal figure change game based on the lottery result of the normal figure lottery. The type of the variation pattern is changed in the same manner as when winning the jackpot symbol A.

  At the time of “low probability + variable”, when the variable variation upper limit number of times (in this embodiment, 100 times) the special figure variation game ends, the gaming state is “low probability + no variable” thereafter. Transition to normal state. For this reason, the type of the general map variation pattern selected by the main control CPU 30a at the start of the general map variation game is changed based on the lottery result of the general map lottery. In other words, a “normal probability variation pattern” in which the variation time is set to “270 (seconds)” is selected as the ordinary diagram variation pattern by “low accuracy + no variation” and transition to the normal state. After that, as described above, the type of the common figure variation pattern to be selected is changed according to the state change by winning the jackpot or winning the symbols C and D.

  As described above, in the pachinko gaming machine according to the present embodiment, in addition to the change in the type of the general-purpose fluctuation pattern based on the state change triggered by the jackpot, the change in the general-purpose fluctuation pattern based on the state change triggered by the loss is realized. ing. For this reason, the player can obtain an advantageous winning increase state as compared with the normal state by winning the symbol C or the symbol D even if the player does not win the jackpot. In the present embodiment, the winning increase state (particularly, the winning increase state triggered by the off symbol C) is a specification that can obtain a profit that approximates the profit obtained in the variable state, so that the winning increase state is entered. You can feel as if you have entered a variable state. As shown in FIG. 4, the winning increase state is generated when “probability change flag = 0, operation flag = 0”, that is, “low probability + no change”, and is distinguished from the change state. It becomes a gaming state.

Therefore, according to the present embodiment, the following effects are obtained.
(1) It is possible to cause a change in the operation mode of the opening / closing blade 16 by changing the normal pattern variation pattern in accordance with the type of outlier symbol derived in the special diagram variation game. That is, since the operation mode of the opening / closing blade 16 is changed without triggering a big hit, even if the big hit is not easily obtained, it is possible to suppress a decrease in the willingness to continue the game. Therefore, the interest can be improved.

  (2) The change control of the normal pattern variation pattern is executed in the non-variable state, that is, in a state that can be disadvantageous for the player. For this reason, a privilege can be given to a player even in an unfavorable state, while giving a privilege by the said change state sufficiently to a player during a variable state. Therefore, the interest can be improved.

  (3) When the usual figure variation pattern that defines the variation time “6 (seconds)” or “40 (seconds)” is selected, the usual figure variation game ends early (the result of whether or not the hit is early) Derived). Therefore, an increase in the number of opening operations of the opening / closing blade 16 per unit time can be expected under the condition that the winning probability of lottery per common figure is the same probability. Therefore, the variation of the gameability (the operation mode of the opening / closing blade 16) during the non-variable state can be increased, and the interest can be improved.

  (4) During the variable speed state and the non-variable variable state, the number of times the opening / closing blade 16 is opened based on the winning of one lottery per common drawing is the same number (three in the embodiment). For this reason, it is possible to balance the playability (the operation mode of the opening / closing blade 16) in the variable state and the non-variable state. That is, either the variable state or the non-variable state can be prevented from being extremely advantageous. In addition, even during the non-variable state, you can get the same sensation as the short state (the period that has been advantageous in the past), and enjoy the game no matter what period you stay Can do.

  (5) Missing symbols C and D, which are the triggers for changing the usual pattern variation pattern, and Missing symbols E, which are the trigger for maintaining the usual diagram variation pattern, are set. For this reason, a variation can be given to the change mode of a common figure fluctuation pattern.

  (6) A plurality of types of ordinary map variation patterns having different variation times are set as the ordinary diagram variation patterns that can be selected in the non-variable state. For this reason, the normal fluctuation pattern that sets the advantage / disadvantage maintains the expectation that the advantageous state will be maintained, the expectation to change from the disadvantageous state to the advantageous state, and the disadvantageous state. Players can have various feelings, such as regret, and can improve their interest.

  (7) In addition, two types of off-line symbols that trigger entry into the winning increase state are set, and the variation time of the normal variation pattern selected in these winning increase states is varied. For this reason, even in the same winning increase state, a difference occurs in the value of the privilege. As a result, variations in game characteristics occur, and the interest can be improved.

In addition, you may change the said embodiment as follows.
-The control related to the change of the normal map variation pattern (the control at the time of disconnection) may be executed during the variable state.

  -You may change specifications, such as a lottery probability, the opening aspect of the opening-and-closing blade 16, and the fluctuation time of a common figure fluctuation pattern. For example, a clear difference between the variable state and the non-variable state may be set for the opening state of the opening / closing blade 16.

  -It is good also considering the type of the loss pattern used as a trigger for a change of a common figure fluctuation pattern to 1 type or 3 types. In addition, two or more types of out-of-line symbols that serve as a trigger for maintaining the normal pattern variation pattern may be used. Moreover, you may change the distribution of the off symbol.

  -The opening time (one time and the whole) of the opening / closing blades 16 based on the winning of one lottery per lottery may be set to the same time during the variable state and the non-variable state. If comprised in this way, the effect similar to the effect (4) of embodiment can be acquired.
