Description

  The present invention relates to a gaming machine, and more particularly to a ball gaming machine such as a so-called pachinko gaming machine.

There are various types of pachinko machines, including seven machines, feathers, and rights. Among them, in pachinko machines called seven machines, the game ball launched on the game board surface enters the starting port, and the design of the variable display device is variably displayed. In the case of a specific symbol, the big winning opening is opened and a jackpot state (special game state) is generated. The big prize opening is once closed when a predetermined number of game balls have won or a predetermined time has elapsed, but is opened again when a predetermined condition is satisfied during the opening, and the opening and closing operations can be performed up to 16 times. It is configured to repeat (16 rounds) (see, for example, Patent Document 1).
JP-A-10-277221

  However, in the conventional gaming machine as described in Patent Document 1, a specific symbol is stopped and displayed on the variable display device only when a jackpot state occurs, but the probability of the jackpot state occurring (Probability that a specific symbol is stopped and displayed) is predetermined (approximately 1/300 to 1/350), and this jackpot state does not occur frequently. For this reason, in the variable display device, the variation display of the out-of-place mode in which the out-of-game pattern in which the big hit state does not occur is displayed in a stopped state (out-of-range variation pattern) rather than the variation display of the big hit mode in which the specific symbol is stopped-displayed (the hit variation pattern). The occurrence frequency of the game was high, and the player had to continue to see the fluctuation display of the detachment mode most of the time during the game. For this reason, the conventional gaming machine has a problem that the game tends to be monotonous and the interest is reduced.

  Further, in the above-described conventional gaming machine, whether or not to generate a big hit state is determined by a lottery process (whether or not) performed by a control device provided in the gaming machine. For this reason, as to whether or not to generate a jackpot state, the player's intention is not reflected at all because the player only follows the unilateral decision of the gaming machine, so the conventional gaming machine tends to be monotonous, There is a problem that interest is reduced.

  Accordingly, in view of the above points, the present invention reduces the occurrence frequency of the variability display of the detachment mode performed by the variable display device, increases the sense of expectation for the jackpot, and diversifies the game contents to improve the game performance. For the purpose.

  Another object of the present invention is to improve the interest of the player by making it possible to reflect the player's intention as to whether or not to generate the jackpot state.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a determination unit for determining whether or not to hit based on a game ball entering a start opening provided in the game board, and a determination unit for determining whether or not the game is successful. The variable display means capable of variably displaying the judgment result as identification information, and can be changed between a closed state in which entry of a game ball is difficult and an open state in which entry of a game ball is easy. A plurality of variable pitching devices that open and close in different opening and closing modes, and a special gaming state occurrence that generates a special gaming state in which the first variable pitching device among the plurality of variable pitching devices opens and closes in the first opening and closing mode Means and
When the identification information stopped and displayed by the variable display means is the first specific symbol, the special game state generating means is activated to generate a special game state, and the identification information stopped and displayed by the variable display means is In the case of the second specific symbol, the second variable pitching device out of the plurality of variable pitching devices gives the player a benefit based on the second opening / closing mode smaller than the first opening / closing mode. An opening / closing operation is performed, and when a game ball that has entered the second variable ball entry device passes a specific area, the special game state means is activated to generate a special game state.

  According to the first aspect of the present invention, when the identification symbol stopped and displayed by the variable display means is the first specific symbol, the special gaming state generating means is activated to generate the special gaming state. Here, as the first specific symbol, when the identification symbol is composed of three numeric symbols of left, middle, and right, the three symbols are all in the same combination (for example, “7 · 7 · 7”, so-called An example can be seen in the order of (Solo). When the special game state generating means is activated, the first variable pitching device performs an opening / closing operation in a first opening / closing mode that has a large benefit to the player. As a first opening / closing mode having a great benefit to the player, after the first variable pitching device is opened, a predetermined number of game balls wins the variable pitching device in the open state, Or the aspect which performs the opening / closing operation | movement which makes it a closed state when predetermined time (1st opening time) passes is repeated predetermined times (for example, 15 times) can be illustrated. Since the first opening time is set to a relatively long time (for example, 30 seconds), according to such a first opening / closing mode, a large number of game balls are won in the first variable pitching device. Can be made. Therefore, if the special game state generating means is activated to generate a special game state, the player can acquire a large amount of prize balls. In the present invention, the special gaming state in which the first variable pitching device performs an opening / closing operation based on the first opening / closing mode is sometimes referred to as “big hit”. The specific symbol may be referred to as a “big hit symbol”.

  Further, when the identification symbol stopped and displayed by the variable display means is the second specific symbol, the second variable pitching device performs the opening / closing operation in the second opening / closing mode with a small benefit to the player. . Here, as the second specific symbol, when the identification symbol is composed of three numeric symbols of left, middle, and right, the three numeric symbols are all the same, but only the middle symbol has a different color (for example, Examples include “red 7, blue 7, red 7”) and combinations in which three numerical symbols are in order (eg, “1, 2, 3”, so-called order). In addition, as a second opening / closing mode that has a small benefit to the player, a time shorter than the opening time (first opening time) of the first variable pitching device after the second variable pitching device is opened. The mode which performs the opening / closing operation | movement made into a closed state once (2nd opening time) passes can be illustrated. The second opening time is set to a short time (for example, 1.8 seconds) such as whether or not a small number (for example, one or two) of game balls can be won. The opening / closing mode of the variable pitching device is less beneficial to the player than the opening / closing mode of the first variable pitching device. In the present invention, the state in which the second variable pitching device performs the opening / closing operation in the second opening / closing mode based on the second opening / closing mode may be referred to as “small hit”. The above-mentioned second specific symbol may be referred to as a “small hit symbol”.

  A specific area is provided in the second variable pitching device, and if the game ball that has entered the second variable pitching device passes the specific area, the special game state generating means is activated. I am going to do it.

  Thus, in the invention described in claim 1, when the identification information stopped and displayed on the variable display means is the first specific symbol (big win symbol), it is a matter of course that the special gaming state (big hit) occurs. Even when the identification information stopped and displayed on the variable display means becomes the second specific symbol (small hit symbol) and a small hit occurs, the second variable input that is opened by the small hit is generated. If the game ball that has entered the ball device passes through a specific area, a special game state (big hit) can be generated. Therefore, according to the first aspect of the present invention, it is possible to increase the player's expectation for the jackpot, diversify the contents of the game, and improve the game performance.

  Further, in the invention according to claim 2, the identification information becomes the second specific symbol and is stopped and displayed on the variable display means from the probability that the identification information becomes the first specific symbol and stopped on the variable display means. It is characterized in that the probability of being set is set higher.

  According to the second aspect of the present invention, since the probability that the second specific symbol (small hit symbol) is stopped and displayed is set high, the variable display means disengages and the symbol is stopped and displayed. The frequency with which the variable display occurs is low. Therefore, it is difficult for the player to continue to watch the change display of the disengagement mode during the game, and the player can have a sense of expectation for the jackpot each time when the jackpot is appropriately generated. Therefore, it is possible to prevent the game from becoming monotonous and enhance the interest of the player.

  In the invention according to claim 3, when the special gaming state generating means is activated when the identification information stopped and displayed on the variable display means becomes the first specific symbol, the first specific symbol is a probability. The identification information stopped or displayed on the variable display means becomes the second specific symbol when the symbol is for variation, and the game ball that has entered the second variable pitching device passes through the specific region. When the special gaming state generating means is activated and the second specific symbol is a probability variation symbol, the identification information is displayed after the operation of the special gaming state generating means is completed. It is characterized by comprising probability changing means for generating a probability changing state in which the probability of being stopped and displayed on the variable display means with a specific design is high.

  In the invention according to claim 3, when the identification symbol stopped and displayed on the variable display means is the first specific symbol, and the first specific symbol is the probability variation symbol, After the end of the special gaming state generated by the stop display, there is a probability that the identification information stopped and displayed on the variable display means will be the first specific symbol or the second specific symbol, in other words, the probability that a big hit or a small hit will occur. The probability fluctuation state becomes higher. In addition, when the identification symbol stopped and displayed on the variable display means is the second specific symbol, and the second specific symbol is the probability variation symbol, the second symbol that has been opened due to the stop display of the symbol. When a special game state occurs when a game ball that has entered the variable ball entry device passes through a specific area, the identification information that is stopped and displayed on the variable display means after the special game state ends is the first information. The probability variation state in which the probability of becoming the specific symbol or the second specific symbol becomes high occurs. That is, in the invention according to claim 3, when the identification symbol at the time of jackpot occurrence is a symbol for probability variation, or the identification symbol at the time of occurrence of a small hit is a symbol for probability variation, When a jackpot occurs, a probability variation state occurs after the jackpot ends.

  According to the third aspect of the present invention, when the second variable pitching device starts operating during the probability variation state (when a small hit occurs), the second specific symbol that is stopped and displayed is a probability. If it is not a symbol for variation, the player must enter the second variable input of the game ball by checking the balance between the remaining number of symbol variation in the probability variation state and the profit obtained in the special game state that does not become the probability variation state after the end. Enter the ball device to enter the special game state and end the probability variation state, or continue the current probability variation state without entering the game ball into the second variable ball entry device, and change the probability It is possible to select whether to wait for the symbol to be stopped and displayed. This makes it possible to reflect the player's intention as to whether or not a special gaming state is to be generated, and to improve the gameability by making the contents of the game diverse.

  In the invention according to claim 4, when the special gaming state generating means is activated when the identification information stopped and displayed on the variable display means becomes the first specific symbol, and the first specific symbol is for the probability variation If it is a symbol, or the identification information stopped and displayed on the variable display means becomes the second specific symbol, the game ball that has entered the second variable pitching device passes through the specific region and the special game When the state generating means is activated, the probability variation state in which the probability that the identification information is stopped and displayed on the variable display means with the first specific symbol or the second specific symbol is increased after the operation of the special gaming state generating means is finished. It is characterized by having a probability variation means for generating.

  In the invention according to claim 4, when the identification symbol stopped and displayed on the variable display means is the first specific symbol and the first specific symbol is the probability variation symbol, After the end of the special gaming state generated by the stop display, there is a probability that the identification information stopped and displayed on the variable display means will be the first specific symbol or the second specific symbol, in other words, the probability that a big hit or a small hit will occur. The probability fluctuation state becomes higher. Further, when the identification symbol stopped and displayed on the variable display means is the second specific symbol, the game ball that has entered the second variable pitching device opened by the stop display of the symbol is specified. When the special gaming state occurs through the area, the probability that the identification information stopped and displayed on the variable display means becomes the first specific symbol or the second specific symbol after the special gaming state ends. A probabilistic fluctuation state occurs. That is, in the invention according to claim 4, if the identification symbol at the time of jackpot occurrence is a symbol for probability variation, or if a jackpot is generated via a jackpot, the probability variation state after the jackpot ends Will occur.

  According to the fourth aspect of the present invention, the identification information stopped and displayed on the variable display means is the second specific symbol, and has entered the second variable pitching device that has been opened. If the game ball passes a specific area, a special game state occurs, and a probability variation state always occurs after the end of the special game state, so that the second specific symbol is activated when the second specific symbol is stopped and displayed. The value of the variable pitching device, that is, the value per hit can be increased. Thereby, the game content can be improved and the gameability can be improved.

  By the way, in the invention according to claim 3, when the player starts the operation of the second variable pitching device in the probability variation state, the player determines whether or not the second specific symbol that is stopped is the probability variation symbol. Therefore, even if the special gaming state is entered, it can be determined whether or not the probability variation state occurs after the special gaming state ends. For this reason, when the second specific symbol stopped and displayed in the probability variation state is not the probability variation symbol, the player does not enter the game ball into the second variable pitching device and does not enter the second variable pitching ball. The device can be deactivated. In this case, the probability variation state may continue for a long time, and the probability variation state may not end.

  In the invention according to claim 4, a special game state (a big hit via a small hit) that occurs when a game ball entering the second variable pitching device passes through a specific area continues multiple times. When this occurs, the probability variation state may continue for a long time, and the probability variation state may not end.

  On the other hand, as in the invention described in claim 5, the probability variation means is configured to terminate the operation at least when the number of times of variation of the identification information reaches a predetermined number of times. The number of times can be limited. Thereby, it can prevent that a probability fluctuation state continues forever, and can prevent that euphoria becomes high remarkably.

Yes.

  As shown in FIG. 2, a substantially circular gaming area 21 is formed in the gaming board 20 by an outer rail 22 and an inner rail 23 provided on the surface of the gaming board 20. In the game area 21, there are a central device 24, a start opening (ordinary electric accessory) 31, a first grand prize device (first variable pitch device) 32, a second grand prize device (second variable pitch device). ) 33, a left winning opening 34, a right winning opening 35, etc. are arranged. In addition, although illustration is abbreviate | omitted, in the game area | region 21, many obstacle nails are arrange | positioned in consideration of the positional balance with each game device.

  The central device 24 is disposed above the substantially central portion of the game area 21. The central device 24 includes a symbol display device (variable display means) 25. In the present embodiment, a liquid crystal display device capable of displaying an arbitrary symbol is used as the symbol display device 25. A special symbol display area (identification information display) that displays one or more special symbols (identification information) while fluctuating one after another in a predetermined direction on the display unit (display surface) 25a of the symbol display device 25, and then stops the display. Region) is formed (not shown). Specifically, the left special symbol display area for displaying the left special symbol, the middle special symbol display area for displaying the middle special symbol, and the right special symbol display area for displaying the right special symbol are set in a substantially horizontal row. They are formed in this order in the arrangement direction (not shown). Each special symbol display area has a direction substantially orthogonal to the arrangement direction of these display areas, in this case, a symbol variation direction is set in the vertical direction, and a plurality of symbols (ID information) as identification information so as to vary in that direction ( Special symbols) are displayed sequentially. The symbol display device 25 shows a specific example of variable display means of the present invention.

  The symbol display device 25 variably displays each special symbol displayed on the display area (not shown) of the display unit (display surface) 25a when a game ball enters a starting port 31 described later. Stop display after a lapse of time. Then, when the symbols are stopped and displayed (determined display) in a state where the symbols are arranged in the same three-digit symbols such as “7, 7, 7”, for example, a special game state in which a special game that is relatively advantageous to the player is executed. In the special game state, the first big prize opening 32a disposed in the first big prize device 32 is opened. When a game ball enters the large winning opening 32a, a predetermined number of game balls (15 in this example) are paid out as prize balls. As described above, in the gaming machine 1 according to the present embodiment, each special symbol is changed (that is, a plurality of pieces of identification information) when the predetermined condition that the game ball enters the start port (ordinary electric accessory) 31 is satisfied. When the symbol stops at a specific symbol such as a symbol with the same three digits, a specific value of jackpot is given.

  Warp entrances (not shown) are provided on the left and right sides of the central device 24. The game ball that has entered the warp entrance is dropped onto a stage (not shown) provided in the central device 24 via a warp passage (not shown). The game ball that has fallen on the stage falls on the front (player side) of the stage after rolling on the stage. Since the start port 31 is disposed below the stage, the possibility that a game ball falling from the stage will win the start port 31 is increased.

  In addition, a normal symbol display area is formed on the display unit 25a of the symbol display device 25 (not shown). The normal symbol display area is formed in a portion that does not interfere with the display of the special symbol (for example, the lower right edge of the display unit 25). In the normal symbol display area, one or a plurality of normal symbols start to change when a game ball passes through either one of the left and right normal symbol operation gates 29 and 30 described later, and is stopped and displayed after a predetermined time has elapsed. When the symbol is stopped and displayed, for example, “7”, the start port 31 is opened for a predetermined time (for example, 0.5 seconds).

  Furthermore, a normal symbol hold display area and a special symbol hold display area are formed on the display unit 25a of the symbol display device 25 (not shown).

  The normal symbol hold display area allows the number of game balls that have passed through the normal symbol operation gates 29 and 30 to be held up to four, and displays the number of holds sequentially for each pass. Each time the next variable display starts, the number of unstarted times (the number of holdings) is consumed, and the number of holdings in the normal symbol holding display area is decreased by one.

  The special symbol hold display area allows the number of game balls that have entered the start port 31 to be held up to four, and displays the number of holds sequentially for each ball entered. Each time the next special symbol change starts, the number of unstarted times is consumed, and the number of reserved symbols in the special symbol hold display area is decreased by one.

  Below the central device 24, normal symbol operation gates 29 and 30 are provided with a start port 31 in between. In these normal symbol operation gates 29 and 30, left and right normal symbol operation gate detection switches 29s and 30s (see FIG. 4) are arranged, respectively. When either of the normal symbol operation gate passage detection switches 29s, 30s detects the passing of the game ball, the normal symbol in the normal symbol display area is variably displayed as described above.

  The start port 31 is disposed below the central position of the central device 24. The start port 31 is a so-called tulip type, and is formed such that a pair of wing pieces are opened and closed on the left and right. Inside the start port 31, there are a start port (ordinary electric accessory) winning detection switch 31s (see FIG. 4) for detecting the passing of the game ball, and a start port (normal electric accessory) for operating the wing piece. A solenoid 31c (see FIG. 7) is provided. When the pair of wing pieces are opened to the left and right, the game ball is likely to enter the game in an open state, and the pair of wing pieces are erected so that the game ball is less likely to enter. .

  In this embodiment, two large winning devices 32 and 33 are provided. The first big prize device 32 is arranged below the start port 31, and the second big prize device 33 is arranged at the upper right of the first big prize device 32. As described above, a predetermined number (15 in this example) of winning balls are paid out for winning of game balls to the big winning openings 32a and 33a.

  In the present embodiment, when the special symbol stopped and displayed on the symbol display device 25 is the first specific symbol (the jackpot symbol), the jackpot (special game state) in which the first big winning device 32 is activated occurs. When the special symbol stopped and displayed on the display device 25 is the second specific symbol (small winning symbol), the small winning that the second big prize winning device 33 operates is generated. The first specific symbol is the same in three special symbols such as “0 · 0 · 0”, “1 · 1 · 1”, “2 · 2 · 2” ... “9 · 9 · 9”, etc. It is possible to make a combination that is uniform in design. The second specific symbols are “0 · 1 · 0”, “1 · 2 · 1”, “2 · 3 · 2”, “4 · 5 · 4”, “6 · 7 · 6”, “8 · It can be a combination of two special symbols out of three special symbols such as “9 · 8” and “9 · 0 · 9”.

  A normal symbol and a probability variation symbol are set in the first specific symbol and the second specific symbol, respectively. The symbol for probability variation is a combination of symbols that generates a probability variation state described later, and the normal symbol is a combination of symbols that does not generate a probability variation state. In the first specific symbol, a specific combination (“3.3.3” and “7.7.7” in this embodiment) among the combinations in which three special symbols are arranged in the same three-digit pattern is used for probability variation. It is a symbol, and a combination of symbols other than those is a normal symbol. In the second specific symbol, a specific combination (in the present embodiment, “3 · 7 · 3” and “7 · 3 · 7”) among the combinations in which three special symbols are arranged with the same two-digit symbol is used for probability variation. It is a symbol, and a combination of symbols other than those is a normal symbol.

  In addition, the probability that the special symbol of the symbol display device 25 is stopped and displayed at the first specific symbol and the first big winning device 32 is activated (hit probability) is set to 1/600, and the special symbol of the symbol display device 25 is The probability (small hit probability) that the second special winning device 33 operates with the second specific symbol being stopped is set to 1/60, which is higher than the probability that the first large winning device 32 operates. These two large winning devices 32 and 33 are opened and closed in different opening and closing modes. The first big winning device 32 operates in the first opening / closing mode, the second big winning device 33 operates in the second opening / closing mode, and the first opening / closing mode is more player than the second opening / closing mode. Is set to increase the profits that can be obtained. In addition, the opening / closing operation | movement of the big winning openings 32a and 33a of the big winning devices 32 and 33 is controlled by the main control part 200 mentioned later.

  When the special symbol stopped and displayed on the symbol display device 25 is the first specific symbol, the main control unit 200 generates a special gaming machine state that is relatively advantageous to the player. In the special gaming machine state, by operating the first grand prize device 32 in the first opening / closing mode, a profit is given to the player regarding the entry of the game ball into the big prize opening 32a. The main control unit 200 corresponds to the special game state generating means of the present invention.

  Here, the opening / closing mode of each of the large winning devices 32 and 33 will be described.

  First, when the operation of the first grand prize winning device 32 is started, the first big prize winning opening 32a is opened to enter a game ball receiving state. This game ball receiving state is ended when the first end condition is satisfied, and the opened first grand prize opening 32a is closed. As a first end condition, when the opening time of the first big winning opening 32a after the start of the game ball receiving state reaches the first predetermined opening time (30 seconds in this embodiment), or in the game ball receiving state After the start, it can be assumed that the number of game balls that have entered the first big prize opening 32a has reached a predetermined number (10 in this embodiment). One round is defined from the start to the end of the game ball receiving state.

  In the first opening / closing mode of the first grand prize winning device 32, after a predetermined time (for example, 0.5 seconds) has elapsed since the end of the game ball receiving state, the first grand prize winning opening 32a is opened to play the game ball again. Accepted and the next round begins. The game ball receiving state in which one round is from the start to the end is repeatedly continued up to a predetermined maximum number of continuous rounds (16 rounds in this embodiment).

  Next, the second grand prize winning device 33 operates when the special symbol stopped and displayed on the symbol display device 25 is a combination of the second specific symbol. By the operation of the second grand prize winning device 33, the second grand prize winning port 33a is opened to enter the game ball receiving state. The game ball receiving state is ended when the second end condition is satisfied, and the opened second large winning opening 33a is closed. As a second end condition, the opening time of the second big winning opening 33a after the start of the game ball receiving state is a second predetermined opening time (1.8 seconds in this embodiment) shorter than the first predetermined opening time. Or when the number of game balls that have entered the second grand prize opening 33a has reached a predetermined number (10 in this embodiment).

  Unlike the first opening / closing mode of the first big winning device 32, the second opening / closing mode in the second big winning device 33 does not continuously start the game ball receiving state once completed. That is, when the round from the start to the end of the game ball receiving state is one round, in the second opening / closing mode, the round is not continued as in the first opening / closing mode, and ends in one round.

  In this embodiment, when the second winning prize port 33a is open while the second big winning device 33 is in operation, the game ball won in the second winning prize port 33a passes a specific area. , It is configured to shift to the above-described special gaming state. Thereby, after the operation of the second grand prize-winning device 33 is finished and the second grand prize-winning port 33a is closed, the operation of the first big prize-winning device 32 is started and the first grand prize-winning port 32a is opened. In this way, when a predetermined condition that a game ball that has won a prize in the second second prize opening 33a passes through a specific area during the operation of the second big prize winning device 33 that operates in the second opening / closing mode, The first grand prize device 32 that operates in the first opening / closing mode, which has a greater profit for the player than in the second opening / closing mode, starts operating (special gaming state occurs). A distribution device (not shown) that distributes the game balls won in the second second prize opening 33a to a specific area and an area other than the specific area is provided inside the second grand prize winning device 33. With this distribution device, the probability that a game ball won in the second second winning opening 33a is distributed to a specific area is set to 1/10.

Specifically, the pre-stored hit design determination random number value is composed of a big hit random number value and a small hit random number value, and these random number values are respectively a random number value for probability variation and a non-probability variation value. The first specific symbol or the second specific symbol is determined according to the acquisition of each random value, and the probability variation symbol or the normal symbol is determined and determined. The displayed symbol is stopped. If the symbol that is stopped and displayed is a symbol for probability variation, the probability of success / failure determination (probability that the special symbol will stop display with a specific symbol) is higher than normal after the above-mentioned special gaming state (5 times in this embodiment) To improve. As a result, the probability that the special symbol stops and displays with the first specific symbol (probability that the first big prize winning device 32 starts to operate) is reduced from 1/600 to 1/125, and the special symbol is The probability of stopping display with a specific symbol of 2 (the probability that the second big prize winning device 33 starts to operate) is reduced from 1/60 to 1/12.

  The probability variation state occurs when (1) when the special symbol is stopped and displayed at the first specific symbol and the first grand prize winning device 32 is activated, the special symbol is the first symbol for probability variation. (2) The special symbol is stopped and displayed at the second specific symbol, the second grand prize winning device 33 starts to operate, and the game ball that has won the second big prize winning port 33a passes through the specific area. Then, when the operation of the second grand prize-winning device 33 is finished and the operation of the first grand prize-winning device 32 is started, the special symbol that causes the operation start of the second big prize-winning device 33 is the second probability variation. There are two types when it is a design.

  The probability variation state is the predetermined number of times (in this example, 50 times) when the next special game state occurs, or when the game ball enters the start port 32 and the symbol display device 25 fluctuates. It ends when it reaches. By the end of the probability variation state, the operation start probability of the first big prize device 32 returns from 1/125 to 1/600, and the operation start probability of the second big prize device 33 returns from 1/12 to 1/60. Become.

  If the first specific symbol or the second specific symbol that causes the occurrence of the next special gaming state is a probability variation symbol, the probability variation state occurs again after the next special gaming state ends, When the first specific symbol or the second specific symbol that causes the occurrence of the next special gaming state is a normal symbol, the probability variation state does not occur after the end of the next special gaming state.

The lamp interface board 261 is provided with drive circuits for various lamps, and is configured as a separate board independent of the sound lamp control board 260a.

  A game effect LED board or the like is connected to the board surface LED board 263 and the game frame LED board 264. These lamps are turned on / off or blinking in accordance with the progress of the game to enhance the gaming effect.

  Further, an amplifier board 265 is connected to the sound lamp control unit 260. A speaker 266 and a volume switch board 267 are connected to the amplifier board 265. From the speaker 266, various sounds, sounds, and the like are output in accordance with the progress of the game. The volume switch board 267 is for setting the output volume of the speaker 266 in accordance with an operation of a volume switch (not shown). The sound lamp control board 260 is provided with a mode changeover switch 268. The mode changeover switch 268 is configured as a DIP switch and is operated by a game hall employee when the power is turned on. The mode changeover switch 268 can change the background and the appearing character in the symbol display device 25.

  Next, the symbol control unit 280 will be described with reference to FIG. FIG. 11 is a block diagram showing various gaming devices connected to the symbol control unit 280. Arithmetic circuit components (not shown) having a CPU, RAM, ROM, input / output port, VDP (video display processor), etc. are provided on the symbol control board 280a provided in the symbol controller 280. It is connected to the main control unit 200.

  As shown in FIG. 11, the symbol control unit 280 is connected to a symbol display device substrate 281 that operates the symbol display device 25. In the symbol control unit 280, the CPU performs display control of the symbol display device 25 using the RAM as a work area according to a control program stored in the ROM. The symbol control unit 280 is provided with a plurality of test signal terminals (not shown) for connecting an external test apparatus (not shown).

  FIG. 12 is a block diagram showing the flow of commands related to symbol control. As shown in FIG. 12, the commands related to symbol control include common commands and symbol control commands. The common command is transmitted from the main control unit 200 to the sound lamp control unit 260. The sound lamp control unit 260 transmits the common command to the symbol control unit 280 as it is. The symbol control command is transmitted to the symbol controller 280 based on the common command received from the main controller 200 by the sound lamp controller 260.

  Also, when the origin sensor 251 cannot detect the origin even after a predetermined time has elapsed after the operation of the firing motor 252, or when the origin sensor 251 continues to detect the origin after the operation of the firing motor 252 for a predetermined time. The payout control unit 230 determines that an abnormality has occurred in the launching device unit, turns on the error LED display unit 4h in red, and stops firing by the launching device unit. An error error of the launcher unit is canceled when the origin can be detected if the origin sensor 251 cannot detect the origin, or when the origin is not detected if the origin sensor 251 continues to detect the origin. Is done. An error signal related to the abnormality of the launcher unit is transmitted from the payout control unit 230 to the main control unit 200 described later.

  Next, jobs executed by the main control unit 200 will be described with reference to FIGS. FIG. 13 shows an example of a main job executed by the CPU 400 of the main control unit 200 based on a program stored in the ROM 403.

  First, the stack pointer is set to a predetermined address in the RAM 402 (S10), and it is determined whether or not the RAM clear switch is operated (pressed) (S12). As a result, when the RAM clear switch is operated, the RAM 402 is initialized (S800). On the other hand, when the RAM clear switch is not operated, it is determined whether or not the backup flag is set (S15). As a result, when the backup flag is set, the “recovery processing for power interruption” shown in FIG. 15 is performed.

  Note that the gaming machine 1 according to the present embodiment performs the processing when the power interruption occurs as shown in the flowchart of FIG. 14 when the power interruption occurs due to a power failure or the like. First, the used register is saved in the RAM 402 (S630), and the value of the stack pointer is saved in the RAM 402 (S632). Then, the special winning opening solenoid 33c and the start opening solenoid 31c are turned off (S634), the polling processing time (for example, about 85 milliseconds) of the winning ball sensor is set (S636), the sensor before counting the winning ball and the sensor after counting the winning ball The passing of the game ball is monitored at (S638). Next, when the polling processing time elapses (S640), a checksum (excluding checksum, backup flag, and stack area) of the RAM 402 being used is created (S642), saved, and the backup flag is set in the RAM 402 ( S646). Then, access to the RAM 402 is prohibited (S648), and an infinite loop process prepares for power down. Note that it is possible to execute HALT processing or STOP processing instead of the unlimited loop processing.

  In the “power recovery process” shown in FIG. 15, a checksum is calculated (S664), and it is determined whether or not it matches the checksum stored when the power is turned off (S666). As a result, if the checksums do not match, the RAM 402 is initialized (S800). On the other hand, if the checksums match, the stack pointer before power-off is restored (S668), the backup flag is cleared (S670), and a command for returning the sub-board to the state before power-off is transmitted. (S672). Then, each register is returned to the state before the power is turned off (S674), the permission / non-permission of the interrupt is returned to the state before the power is turned off (S676, S678), and the address is returned to the address before the power is turned off (S680). In this embodiment, since a backup power supply for power failure countermeasures is added to the gaming machine 1, "information advantageous to the player" that was generated before the power outage was saved even during a pachinko hall power outage, etc. it can.

  Returning to FIG. 13, if it is determined in step S15 that the backup flag is not set, the initialization end is determined (S20). As a result, if the initialization has not ended, the initialization end determination in S20 is performed again after executing the initialization job (S190). Note that the initialization process of the RAM 402 is performed when the gaming machine 1 is turned on for the first time from the shipping state, when the RAM clear switch is operated (pressed), when the backup flag is abnormal, and the checksum matches. It is done when there is not.

  On the other hand, when the initialization is completed, each job from the LED job (S30) to the switch job (S70) is executed. In the LED job (S30), the display pattern data of the normal symbol and the normal symbol unstarted count, the display pattern data of the special symbol unstarted count, and the like are output. In the constant speed random number job (S40), a special symbol success / failure random number memory, a general-purpose count memory, and the like in the RAM 402, which will be described later, are updated. In the non-constant speed random number job (S50), the initial value counter and the off-normal symbol random number memory (not shown) are updated. The general-purpose count memory (not shown) is used, for example, for creating values “0” to “255” for each interrupt, executing command jobs, and decoration jobs.

  In the voice job (S60), data related to music and voice is read, and in the switch job (S70), various detection switches are read. That is, various signals such as a left / right winning opening passing detection signal are captured by the main control unit 200 via the relay board 210, and various signals such as a firing stop detection signal and a touch detection signal are captured by the firing control unit 250. In addition, the main control unit 200 receives the start port winning detection signal from the start port winning detection switch 31s, and receives the winning ball detection signal and the normal symbol operation gate passage detection signal from the winning ball detection switches 32s and 33s.

  Next, it is determined whether or not there is an abnormality in various switches such as a count detection switch and count detection (S80). As a result, if there is an abnormality (ball clogging or disconnection), an error job (S130) is executed.

  On the other hand, if there is no abnormality, a special symbol main job (S90) and a normal symbol job (S100) are executed. In the special symbol main job (S90), a job related to data necessary for the main controller 200 and the symbol controller 280 to operate in cooperation is executed. Further, in the normal symbol main job (S100), the display pattern data of the normal symbol and the normal symbol unstarted count is read.

  Thereafter, the state of each flag is set in the backup memory (S140), and a prize ball signal job (S150), an information signal job (S160), a command job (S170), and a remaining time job (S180) are executed. In the prize ball signal job (S150), data relating to prize ball payout is read and output, and in the information signal job (S160), data necessary for outputting information to other control units is read. Further, in the command job (S170), a command for special symbol management or the like is output, and in the remaining time job (S180), a non-constant random number is called. Note that the initial value random number is also updated in the remaining time job of S180.

  Next, the success / failure determination job executed in the series of the main job will be described with reference to the flowcharts of FIGS. 16 is a flowchart of the success / failure determination job, FIG. 17 is a flowchart of the jackpot process, and FIG. 18 is a flowchart of the losing process. The success / failure determination job is executed at the time of starting winning, that is, when winning at the starting port 31. In these jobs, various memories stored in the built-in RAM 402 of the main control unit 200 shown in FIG. 6 are used.

  First, as shown in FIG. 16, it is determined whether or not there is a start winning (S200). As a result, if there is no start prize, the process skips to S250 and confirms whether there is a hold (S250). As a result, when there is no hold (when the number of holds is zero), the process returns to S200, and when there is a hold (when the number of holds is 1 to 4), the process proceeds to S255.

  On the other hand, if there is a start winning, it is determined whether or not the number of pending (unstarted number) exceeds a certain value (“4” in this embodiment) (S210). If the number of reserves (the number of unstarted times) exceeds a certain value, the start winning is invalid and skips to S255. On the other hand, if the number of holdings (the number of unstarted times) does not exceed a certain value, the number of holdings stored in the special symbol holding number memory 402b is increased by 1 (S220).

  Next, a special symbol success / failure determination random number (hereinafter also referred to as a success / failure random number or a determination random number) is generated (randomness determination random number generation means) and read (S230). The validity random number generation means may use software or hardware. The read determination random number value is stored in a special symbol success / failure determination random number memory 402a (hereinafter also referred to as a determination random number memory) (S240). In this memory, the read determination random number value is stored in the shift memory format in the time series of the start winning prize.

  Next, the oldest first determination random value stored in the determination random number memory 402a is read (S255), and the winning number (the winning determination value) is read from the big hit number memory in the ROM 403 (S260). Then, it is determined whether or not the determined random number value matches the winning number (S265). As a result, if both match, a hit determination is made and a hit process is performed (S270). If they do not match, a hit determination is made and a drop process is performed (S310).

  Next, the winning process (S270) will be described with reference to FIG. First, a winning design determination random number (identification information determination random number) is generated and read (S280). The read determined random number value is stored in the symbol determination random number memory 402d (S290). The winning symbol determination random number is read at the same time as the random number for success / failure at the time of starting winning, but may be read simultaneously with the determination of winning determination or after a predetermined time after determining the winning determination.

  Next, a reach mode determination random number is generated simultaneously with the winning symbol determination random number, and is read and stored in the reach mode determination random number memory 402k (S295). Further, the determination result of “win” (“1” in this embodiment) is stored in the determination result memory 402j (S300).

  The special symbol designated by the winning symbol determination random number value is determined based on the special symbol image data stored in the ROM of the symbol control unit 280, and after being subjected to a variable display state on the symbol display device 25, (For example, an arrangement mode of big hits of “7 · 7 · 7” or an arrangement mode of small hits of “7 · 3 · 7”). The special symbol image data is stored in the RAM 402 of the main control unit 200 as an identification information determination value in association with the winning symbol determination random value, and the read symbol determination random value and the identification information determination value are read. It is good also as what determines the symbol stopped and displayed by comparing.

  Further, the reach display mode specified by the reach mode determination random number value is determined after the variable display state is passed to the symbol display device 25 based on the reach display mode image data stored in the ROM of the symbol control unit 280. Displayed in a reach form. In this case as well, the reach display mode image data is stored in the reach mode determination value memory 402l of the RAM 402 of the main control unit 200 as a reach mode determination value in association with the reach mode determination random value, and read. The reach mode to be displayed may be determined by comparing the reach mode determination random number value with the reach mode determination value.

  Next, the detachment process (S310) will be described with reference to FIG. First, it is determined by a random number whether or not an outreach job is performed. Specifically, a reach mode determining random number is generated, read (S315), and the reach number stored in the reach number memory 402i is read (S320). If the reach mode determination random number and the reach number match, it becomes a missed reach job, and if it does not match, it becomes a normal missed job (S330).

  In the case of a miss reach job, at least two special symbols to be aligned (for example, the left symbol and the right symbol among the three types of special symbols) are determined using the miss reach symbol determination random number (S340). Or you may make it match the right design with it referring to the random number of the left design. The determined symbol is removed and stored in the reach symbol number memory 402m (S350). Further, the out-of-line symbol is similarly determined by a random number (S360), and the determined random number value is stored in the out-of-line symbol number memory 402g (S370). Then, the determination result of “outgoing reach” (“2” in this embodiment) is stored in the determination result memory 402j (S380).

  On the other hand, in the case of a normal off-job, each special symbol (for example, left symbol, right symbol, middle symbol) is determined by random numbers, and the determined random number values are stored in the corresponding off symbol number memories 402e, 402f, and 402g. (S390 to S440). In addition, the determination result “normally off” (“3” in the present embodiment) is stored in the determination result memory 402j (S450).

  Next, the general flow of the special symbol main job executed in the series of the main job will be described with reference to the flowchart of FIG.

  First, based on the winning of a game ball at the start port 31, the display of variation of each special symbol is started on the symbol display device 25 (S500). For example, the left and right and middle symbols are scrolled from top to bottom and from bottom to top.

  Next, the determination result for each winning obtained in the success / failure determination job shown in FIGS. 16 to 18 is read from the determination result memory 402j (S510), and it is determined whether or not the determination result is a win determination (S520).

  As a result, in the case of a hit determination (“1”), the reach mode determining value stored in the reach mode determining value memory 402l corresponding to the above-described reach mode determining random value is read (S580), and the hit number ( The identification information determination value) is read from the hit number memory (determination value storage means) (S600). Next, proceeding to S610, for example, the left symbol and the right symbol are aligned to the same symbol, and after a predetermined reach display mode, the display is stopped and confirmed so as to become the first specific symbol or the second specific symbol described above. (S610).

  On the other hand, if it is not a hit determination, it is determined whether or not it is a missed reach determination (“2”) (S530). As a result, in the case of the detachment reach determination (“2”), the detachment symbol number is read from the above-described detachment symbol number memory 402m, and the detaching symbol number is read from the detaching symbol number memory 402g (S570). Then, a difference between the number of the outreach symbol number and the number of the outlying symbol number (for example, the difference between the left symbol and the middle symbol) is calculated (S571). Determine (S572). For example, when the middle symbol is the symbol immediately before the left symbol and the difference is “−1”, one type is selected from a plurality of types (for example, three types) outliers (for example, a predetermined random number). Can be selected by acquisition) and read. Thereafter, for example, after the left symbol and the right symbol are aligned to the same symbol and subjected to a predetermined reach display mode, the middle symbol is stopped and displayed with a symbol different from the other symbols (S610).

  On the other hand, if it is not outlier reach determination, it is normal outage determination ("3") (S540), each outlier symbol number is read from each outnumber memory 402e, 402f, 402g (S550), and each special symbol (for example, , The left symbol, the right symbol, and the middle symbol) are stopped and displayed at a timing shifted from each other (S560). Even in the case of normal deviation determination, the display mode can be changed to various modes by “slip display” or the like. In this case, the display mode image data is stored in a normal out display mode determination value memory (not shown) in the RAM 402 of the main control unit 200 as a normal out display mode determination value in association with the reach mode determination random number value. Alternatively, it is also possible to determine the normal off mode to be displayed by comparing the read reach mode determining random number value with the normal off display mode determining value.

  When the winning determination is made, a special symbol is confirmed and displayed on the symbol display device 25 by a combination of the first specific symbol or the second specific symbol, and the first big winning device 32 or the second big winning device 33 is displayed. The operation starts in each opening and closing mode. When a special symbol is confirmed and displayed by the combination of the first specific symbols on the symbol display device 25, or when a game ball passes through a specific area provided in the second big prize winning device 33, the special gaming state is set. Become.

  Next, the variable winning job will be described based on the flowchart of FIG. First, it is determined whether or not the first big prize opening 32a is open, that is, whether or not the first big prize winning device 32 is operating (a special gaming state is occurring) (S700). As a result, when it is determined that the first big prize opening 32a is not being opened (S700: NO), it is judged whether or not the game ball has passed through a specific area in the second big prize opening 33a ( S7001). As a result, when it is determined that the game ball has passed the specific area (S7001: YES), the first big winning device 32 is activated (the special gaming state generating device is activated). The winning opening 32a is opened (S704). On the other hand, if it is determined that the game ball has not passed through the specific area (S7001: NO), whether or not the second big prize opening 33a is open, that is, the second big prize winning device 33 is operating. It is determined whether or not there is (S701). As a result, when it is determined that the second grand prize winning opening 33a is not open (S701: NO), it is determined whether or not the winning determination is made in the above-described determination processing in S265 (S702). As a result, when it is not a hit determination (S702: NO), the process directly returns.

  On the other hand, when it is a hit determination (S702: YES), it is determined whether or not the special symbol stopped and displayed on the symbol display device 25 is the first specific symbol (S703). As a result, when the special symbol is the first specific symbol (when it is a big hit) (S703: YES), the first big prize winning device 32 is started to operate and the first big prize winning opening 32a is opened. (S704). On the other hand, when the special symbol is not the first special symbol (S703: NO), that is, when the special symbol is the second specific symbol (when it is a small hit), the second big winning device 33. Is started, and the second big prize opening 33a is opened (S705).

  Next, in the determination process of S700, when it is determined that the first big prize opening 32a is being opened (S700: YES), the first big prize opening 32a is opened and the first big prize opening 32a is opened. It is determined whether or not a predetermined number (10 in this example) of game balls have entered the winning opening 32a (S706). As a result, when it is determined that a predetermined number of game balls have not entered the first grand prize opening 32a (S706: NO), a predetermined time (after the first big prize opening 32a is opened) It is determined whether or not 30 seconds has elapsed in this example (S707). As a result, when the predetermined time has not elapsed (S707: NO), the process returns as it is.

  On the other hand, when there is a predetermined number of balls in the first grand prize opening 32a (S706: NO), or a predetermined time (30 seconds in this example) has elapsed since the first big prize opening 32a is opened. If it is (S707: YES), the first grand prize opening 32a is closed (S708), and the number of rounds after the occurrence of the special gaming state is less than a predetermined number of rounds (16 rounds in this example). Is determined (S709). As a result, when it is determined that the number is less than the predetermined number of rounds (S709: YES), the first big prize opening 32a is again opened (S710).

  On the other hand, if it is determined that the number of rounds after the occurrence of the special gaming state is less than the predetermined number of rounds (S709: NO), whether the special symbol stopped and displayed on the symbol display device 25 is a symbol for probability variation It is determined whether or not (S711). As a result, when the special symbol stopped and displayed on the symbol display device 25 is not the symbol for probability variation (S711: NO), the process returns as it is, and the special symbol stopped and displayed on the symbol display device 25 is the symbol for probability variation. If there is (S711: YES), a probability fluctuation state is generated (S712).

  If it is determined in the process of S701 that the second big prize opening 33a is in an open state (S701: YES), a predetermined number (10 in this example) of game balls enter the second big prize opening 33a. It is determined whether or not the ball has been made (S713). As a result, when it is determined that a predetermined number of game balls have not entered the second grand prize opening 33a (S713: NO), a predetermined time (this example) after the second big prize opening 33a is opened. It is determined whether or not 1.8 seconds has elapsed (S714). As a result, when it is determined that the predetermined time has not elapsed since the second grand prize opening 33a is opened (S714: NO), the process returns as it is and the second big prize opening 33a is opened after the predetermined time. If it is determined that the time has passed (S714: YES), the second big prize opening 33a is closed (S715).

  If it is determined in the process of S713 that a game ball has entered the second big prize opening 33a (S713: YES), the second big prize opening 33a is closed (S715).

Next, the probability variation job will be described based on the flowchart of FIG.
It is determined whether or not the state is a probability fluctuation state (S750). As a result, when it is determined that the state is not the probability variation state (S750: NO), the process directly returns. On the other hand, if the state is a probability variation state (S750: YES), it is determined whether or not a special gaming state has occurred in the above-described processing of S704 (S751).

  As a result, when it is determined that a special gaming state has occurred (S751: YES), the probability variation state is terminated (S753). On the other hand, if it is determined that the special gaming state has not occurred (S751: NO), the total number of changes of the special symbol since the probability variation state has occurred is a predetermined number (50 in this example). It is determined whether or not it has been reached (S752). As a result, when the number of fluctuations of the special symbol has reached the predetermined number (S752: YES), the probability fluctuation state is terminated (S753). On the other hand, when the number of fluctuations of the special symbol has not reached the predetermined number (S752: NO), the process returns as it is.

  As described above, when the first specific symbol is stopped and displayed on the symbol display device 25, the first large winning opening 32a is opened and the first opening / closing mode that allows the round to continue is operated. When the second specific symbol is stopped and displayed on the symbol winning device 32 and the symbol display device 25, the second symbol winning device that operates in the second opening / closing mode that only opens the second symbol winning opening 33a once. 33, which is opened in response to the second specific symbol being stopped and displayed on the symbol display device 25 in addition to the case where the first specific symbol is stopped and displayed on the symbol display device 25. When the game ball passes through a specific area in the winning opening 33a, a special gaming state (big win) in which the first big winning device 32 operates is generated, so that the player's expectation for the big hit is increased and the game To make the contents of It can, thereby improving the gaming properties.

  In addition, the first grand prize winning device 33 represents the operation start probability of the second big prize winning device 33 that operates in the second opening and closing mode, which is less profitable to the player than the first big winning unit 32 that operates in the first opening and closing mode. By making it larger than the operation start probability of 32, the occurrence frequency of the detachment mode is reduced in the variable display performed in the symbol display device 25, and the small hits are generated appropriately. You can have a sense of expectation. Thereby, it can prevent that a game becomes monotonous and can raise the interest of a player.

  In addition, when the second grand prize device 33 starts operating, the player can determine whether or not the second specific symbol that is stopped and displayed is the probability variation symbol, so that the game is temporarily placed in the second major prize opening 33a. Even if a ball is inserted to pass through a specific area and transition to the special game state, it can be determined whether or not the probability variation state occurs after the special game state ends. For this reason, when the player starts the second grand prize winning device 33 during the probability variation state, if the second specific symbol that has been stopped is not the probability variation symbol, the game ball is placed in the second major prize opening 33a. The operation of the second large winning device 33 can be terminated without entering the ball. In this case, the probability variation state may continue even after the operation of the second grand prize winning device 33 is completed, and the probability variation state may not be terminated. On the other hand, in the present embodiment, since the number of symbol fluctuations in the probability fluctuation state is limited, it is possible to prevent the probability fluctuation state from continuing forever.

  In addition, as described above, when the second large winning device 33 starts operating in the probability variation state, if the second specific symbol that is stopped and displayed is not the probability variation symbol, the player selects the second game ball. It is possible to select whether to enter the special winning state 33a to enter the special winning opening 33a or to continue the probability variation state without entering the gaming ball into the second large winning opening 33a. Specifically, when the second specific symbol stopped and displayed on the symbol display device 25 in the probability variation state is a normal symbol, and the remaining number of symbol variations in the probability variation state is large, the special game Since the state can be expected to occur again, the probability variation state is stopped and displayed on the symbol display device 25 by continuing the probability variation state without causing the game ball to enter the second grand prize opening 33a. When the remaining number of symbol fluctuations in the probability variation state is small, it is difficult to expect the special game state to occur again, so the game ball is placed in the second big prize opening 33a. To enter the special game state. In this way, when a small hit occurs in the probability variation state, the player himself / herself combines the balance of the remaining number of symbol variations in the probability variation state with the profit obtained in the special gaming state that does not become the probability variation state after the end. And the player can decide whether or not to generate a special gaming state based on his / her choice. This makes it possible to reflect the player's intention as to whether or not a special gaming state is to be generated, so that the game content can be improved and the gaming characteristics can be improved.

(Other embodiments)
In the above embodiment, when the second large winning device 33 starts operating in the probability variation state, if the second specific symbol that is stopped is not the probability variation symbol, the player continues the probability variation state. In order to prevent the game ball from entering the second grand prize opening 33a, the second big prize opening 33a is closed after a lapse of a predetermined time.
