Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine having a display control function for making a lottery drawing by variably displaying a predetermined symbol on an image display device.

  Conventionally, game machines have been devised in various ways to improve their preferences. In particular, a gaming machine equipped with an image display device on a gaming area has various contrivances because the popularity and unpopularity of the gaming machine is determined depending on the display method of the image display device. As a game machine equipped with a typical image display device, for example, there is a so-called fever-type pachinko game machine, and this type of game is specially provided in an image display section of a special symbol display device as an image display device such as a liquid crystal display device. Three symbol display parts for displaying symbols are set, and a pseudo pattern showing a state where a picture, a character, a number, a symbol, a character, etc. as a special symbol is rotated on each symbol display part on the basis of a winning of a start winning opening. The variable display as an image is displayed, the variable display is stopped after a lapse of a predetermined time, and the stopped special symbols are matched (hereinafter also referred to as a slot game).

  As a result of the slot game, when the stop symbol of each symbol display unit is a predetermined special symbol combination (big hit symbol), the gaming state is shifted to a jackpot game that is extremely valuable to the player. ing. The probability of becoming a jackpot symbol is set in advance to a predetermined probability (hit probability), and the jackpot game generally has a big winning mouth called an attacker during a plurality of rounds (for example, the first round to the 16th round). It is converted into a state advantageous to the player in a predetermined manner. Therefore, the player can acquire a large number of game balls (for example, about 2000 balls) by this jackpot game, and how many game balls are awarded at the start winning opening is the biggest concern of the game. Yes.

  Among the gaming machines equipped with jackpot games, the most popular gaming machine in the market at present is the “gaming machine with probability variation function (pachinko gaming machine)”, and this gaming machine with probability variation function is specified. When a big hit with a big hit symbol (for example, an odd number of double eyes), the big hit probability (lottery probability) in the slot game becomes a special game state that is advantageous to the player such as a probability variation state in which the probability is maintained at a high probability. This probability variation state is maintained until the next big hit or until a predetermined number of slot games are executed. As a result, the player can have a chance to continuously generate a plurality of big hits (so-called continuous chain) by one big hit with a specific big hit symbol, that is, the player can obtain a large amount of big hits. A game ball can be acquired at once (for example, refer to Patent Document 1, hereinafter referred to as Prior Art 1).

Further, in such a fever-type pachinko machine, when a game ball wins a start winning slot during a slot game, the slot game corresponding to the winning is temporarily suspended, and after the currently executed slot game is ended. The slot game is executed as many times as the number of times of suspension, which is normally up to four times. The slot game is not executed as an overflow for winning at the start winning opening exceeding the maximum number (for example, refer to Patent Document 2 and hereinafter referred to as Prior Art 2).
Japanese Patent Laid-Open No. 9-182846 JP 2003-24602 A

  However, in such a gaming machine with the probability variation function of the prior art 1, a large amount of game balls will be paid out when a specific jackpot symbol is generated, so that the jackpot probability is inevitably set low for business purposes. It has become. Therefore, the player can acquire a large number of game balls at a stretch when the player is in good condition, but on the other hand, if the player is in a bad condition, the player may not be able to acquire a big hit. The gaming machine equipped with the probability variation function of technology 1 has a very strong gaming property.

  Further, in the above-described prior art 2, in order to prevent the player from overflowing, an operation to intermittently stop the launching device that launches the game ball into the game area, that is, stop-stopping, is performed. As a result, the operating rate of the gaming machine is lowered, which is not preferable for the amusement hall because it leads to a decrease in sales. Also, this stop operation is troublesome for the player, and if an overflow occurs, the slot game will not be executed even though the game ball has won the start winning opening, and the player's willingness to play There is also a problem of lowering.

The present invention has been made to solve at least one of the above problems, it is an object of probability variation function can be also improved interest for games while appropriately suppressed the gambling properties It is in providing the gaming machine provided with.

In order to solve such a problem, the gaming machine according to the present invention includes a first starting gaming device and a second starting gaming device that are capable of winning or passing a game ball, It can be converted into a state that is advantageous to the player and a state that is disadvantageous for the first image display device and the second image display device that display the slot game based on the big win lottery by stopping and confirming the symbol after the change A first variable winning device, a second variable winning device, a first game ball detecting means for detecting a game ball that has won or passed through the first starting game device, and a game ball that has won or passed through the second starting game device; Second game ball detection means to detect and the first game ball detection means or the second game ball detection means to detect a game ball based on the set first big hit probability or second big hit probability Control means for performing the jackpot lottery and causing the first image display device or the second image display device to execute the slot game reflecting the result of the jackpot lottery, and the result of the slot game, the first image display device Alternatively, if the symbol that is confirmed and displayed on the second image display device is a jackpot symbol, it is a big hit, and the first variable winning device or the second variable winning device is controlled to be converted into a predetermined mode, which is advantageous for the player. When a special game generating means for generating a special game and a symbol determined and displayed on the first image display device or the second image display device as a result of the slot game are a specific symbol, at least the first game A gaming machine comprising a jackpot probability increasing means for increasing the jackpot probability or the second jackpot probability, wherein the gaming machine is increased by the jackpot probability increasing means. When the first big hit probability or the second big hit probability is increased, a first game game is performed in which the game ball wins or passes through the first starting game device and the slot game is executed on the first image display device. Based on the establishment of the second game condition that the game ball is won or passed through the second start game device and the slot game is executed on the second image display device, the rising second game condition is established. A jackpot probability lowering means for lowering the first jackpot probability or the second jackpot probability based on the first lottery probability or the second lottery probability that is higher than the first lottery probability, and winning or passing through the first starting gaming machine. A game ball that wins or passes through the first start game device, and a second game ball such that a percentage of game balls is lower than a rate of game balls that win or pass through the second start game device; And a winning percentage setting means for setting a percentage of a game ball winning or passing through the starting game device by a game nail or a ball guidance device provided in a game area where the game ball falls .

Further, the gaming machine according to claim 2 is the gaming machine according to claim 1 , informing which of the first lottery probability and the second lottery probability is advantageous or disadvantageous for the player. It has a lottery probability notification means.

Further, in the gaming machine according to claim 3 , in the gaming machine according to claim 1 or 2 , the jackpot probability increasing means is a program related to the slot game executed in the first image display device. The first big hit probability is raised higher than the second big hit probability related to the slot game executed in the second image display device.

The gaming machine according to claim 4 is the gaming machine according to any one of claims 1 to 3, wherein the special game is displayed when the jackpot symbol is confirmed and displayed on the first image display device. And a second special game that is generated when a jackpot symbol is confirmed and displayed on the second image display device. The first special game is more effective than the second special game. Is also advantageous for the player.

The gaming machine according to claim 5 is the gaming machine according to any one of claims 1 to 4 , wherein the first lottery probability and the second lottery probability are determined according to a predetermined third gaming condition. It is characterized by being exchanged and applied based on establishment.

Further, in the gaming machine according to claim 6 , in the gaming machine according to claim 5 , the predetermined third gaming condition is established when a predetermined variation pattern or character is displayed in the slot game. It is characterized by that.

A gaming machine according to claim 7 is the gaming machine according to any one of claims 1 to 6 , wherein the first lottery probability and the second lottery probability are set according to an operation from outside the gaming machine. A probability setting means that can be set is provided.

The gaming machine according to claim 8 is the gaming machine according to any one of claims 1 to 7 , wherein the first image display device and the second image display device are integrated with each other. The image display unit is divided into two parts.
The gaming machine according to claim 9 is the gaming machine according to any one of claims 1 to 7, wherein the first image display device and the second image display device are formed separately. It is characterized by being.

  According to the first aspect of the present invention, for example, a first start game device and a second start game device as a start winning opening, an operation gate, and the like are provided in the game area, and a proximity sensor detects a winning or passing of a game ball to the first start game device. The first game ball detecting means such as the first game ball detecting means, and the winning or passing of the game ball to the second starting gaming machine is similarly detected by the second game ball detecting means such as a proximity sensor. Then, due to the fact that the first game ball detecting means detects the winning or passing of the game ball, the control means performs a big hit lottery based on the set first big hit probability, and at least in the first image display device. A slot game display reflecting the result of the big win lottery is executed by stopping and confirming a predetermined symbol after the change.

  Similarly, the control means performs a big hit lottery based on the set second big hit probability due to the second game ball detecting means detecting the winning or passing of the game ball, and the second image display device Then, at least a predetermined symbol is stopped after being changed, and the slot game is displayed reflecting the result of the big win lottery. That is, when a game ball wins or passes through the first starting gaming device, a slot game is played on the first image display device, and when a game ball wins or passes through the second starting gaming device, a slot game is played on the second image display device. Is done.

  As a result of the slot game, if the symbol confirmed and displayed on the first image display device is a jackpot symbol, for example, a predetermined symbol (777) in the form of a doublet, it is a jackpot, and the special game generating means The first variable prize-winning device that can be converted into an advantageous state and an unfavorable state for the player is set in a predetermined manner, for example, when it is open, it is easy to accept a game ball, and when it is closed, no game ball is accepted A winning device such as an attacker that can be converted into a state is controlled to be repeatedly opened a plurality of times for a predetermined time, thereby generating a special game advantageous to the player.

  Similarly, when the symbol that is confirmed and displayed on the second image display device is a jackpot symbol, the special game generating means converts the second variable prize-winning device into a predetermined mode to control the special game advantageous to the player. Is generated. That is, a special game in which the first variable winning device is controlled to be converted when the jackpot symbol is displayed on the first image display device, and the second variable winning device is displayed when the jackpot symbol is displayed on the second image display device. A special game to be controlled is generated.

  Note that the slot game is not limited to a combination of a plurality of symbols (for example, a three-digit symbol), but may be a single symbol (for example, a one-digit symbol), for example. Both symbols are provided, and multiple symbols are displayed large as pseudo symbols, while a single symbol is displayed small as a symbol related to a real jackpot lottery, and a single symbol display result (for example, a big hit) is displayed as multiple symbols. The case where it is expressed in a manner reflected in the display result is also included.

  Further, when the symbol determined and displayed on the first image display device is a specific symbol as a result of the slot game, the big hit probability increasing means increases at least the first big hit probability. Similarly, when the symbol determined and displayed on the second image display device is a specific symbol as a result of the slot game, the big hit probability increasing means increases at least the second big hit probability. That is, the first big hit probability increases when a specific symbol is displayed on the first image display device, and the second big hit probability increases when the specific symbol is displayed on the second image display device. In these cases, in addition to the increase in the first big hit probability or the second big hit probability, a privilege that makes it advantageous for the player to acquire a special game may be further given. That is, when a specific symbol is confirmed and displayed on the first image display device or the second image display device, a gaming state is achieved in which it is advantageous for the player to acquire a special game. It should be noted that the specific symbol may also serve as a jackpot symbol, and the first jackpot probability and the second jackpot probability may be the same probability.

  In such a gaming machine, when the first big hit probability is increased by the big hit probability increasing means, the big hit probability decreasing means is based on the establishment of the predetermined first gaming condition, Reduce the probability. Similarly, when the second big hit probability is increased by the big hit probability increasing means, the big hit probability reducing means decreases the increasing second big hit probability based on the establishment of a predetermined second game condition.

  In other words, in the present invention, when a specific symbol is fixedly displayed on the first image display device, the subsequent first image display device reflects a result of the big hit lottery performed with the increased first big hit probability. Although the game is executed, when the predetermined first game condition is satisfied, the rising first big hit probability is lowered. Therefore, when the first big hit probability is lowered, In the slot game in the first image display device, the slot game reflecting the result of the big hit lottery performed with the reduced first big hit probability is executed.

  Similarly, when a specific symbol is finalized and displayed on the second image display device, the subsequent second image display device executes a slot game reflecting the result of the big hit lottery performed with the increased second big hit probability. However, when the predetermined second gaming condition is satisfied, the rising second big hit probability is lowered. Therefore, when the second big hit probability is lowered, the second image after that In the slot game on the display device, a slot game reflecting the result of the jackpot lottery performed with the reduced second jackpot probability is executed.

  Therefore, in the gaming machine according to the invention of claim 1 having such a configuration, the player can enjoy the game related to the two big hits with one gaming machine while demonstrating his / her skill. The big hit probability (the first big hit probability or the second big hit probability) is maintained in an elevated state, and the big hits are continuously generated to prevent a large amount of game balls from being paid out to the player as prize balls in a short time. Therefore, the number of prize balls per unit time can be averaged by setting a relatively high probability of hitting in the normal gaming state (the probability of hitting the first hit or the second hit before rising). It is possible to improve the fun of the game while moderately reducing gambling.

By the way, various jackpot probability lowering means for lowering the rising first jackpot probability or the second jackpot probability can be considered, and this may be performed as follows. In other words, a large contact probability reducing means and big hit probability decreases selecting means, the big hit probability decreases lottery means lowers at lottery based first big hit probability has risen to the first lottery probability. Similarly, the big hit probability reduction lottery means lowers the rising second big hit probability by lottery based on the second lottery probability. Here, the first lottery probability and the second lottery probability are different from each other.

That is, according to the present invention, when the first big hit probability is increased, the lottery for decreasing the first big hit probability is executed with the first lottery probability when the predetermined first game condition is satisfied, and the second big hit probability is When it is rising, a lottery for reducing the second big hit probability is executed at a second lottery probability different from the first lottery probability when a predetermined second game condition is satisfied. Thus, according to the invention of claim 1 according to this structure has a great interest in either holds a predetermined first game condition or the second game condition to Yu technique's, resulting in improved taste of a game To do.

The gaming machine according to claim 2 is the gaming machine according to claim 1 , further comprising a lottery probability informing means, wherein the lottery probability informing means determines which of the first lottery probability and the second lottery probability is a game. Whether it is advantageous or disadvantageous for a person. Here, as the lottery probability notification means, the first image display device and the second image display device are used. For example, when the second lottery probability is more disadvantageous for the player than the first lottery probability, the background of the first image display device. The image is displayed in red, the background image of the second image display device is displayed in gray or the like, or indirectly notified, or an effect display using a character or the like is displayed and the fact is suggested. good. Alternatively, a separate display device may be provided to display the probability values of the first lottery probability and the second lottery probability and notify them directly, or may notify them by voice or the like. Therefore, according to the invention of claim 2 having such a configuration, in addition to the effect of the invention of claim 1 , the player does not satisfy the predetermined first game condition or the second game condition which is disadvantageous to himself even if it is bad. As a result, technical intervention is made in the game, and as a result, the taste of the game is further improved.

By the way, a predetermined first game condition for executing the lottery for reducing the rising first big hit probability and a predetermined second for executing the lottery for reducing the rising second big hit probability. Various game conditions may be established, but this is preferably performed as follows. That is, in the gaming machine according to claim 1 , when the game ball wins or passes through the first starting gaming device and the slot game is executed on the first image display device, the predetermined first gaming condition is satisfied, A predetermined second game condition is established when a game ball wins or passes through the second starting game device and a slot game is executed on the second image display device.

Slot game, since it is the first big hit probability or second jackpot based on the probability perform lottery jackpot game is set as described above, as described in claim 1, gaming ball first start gaming machine If the slot game is executed on the first image display device after winning or passing the first game condition, the lottery to reduce the first big hit probability is performed as the establishment of the predetermined first game condition, or the game ball is If a lottery is performed to reduce the second big hit probability when a predetermined second game condition is satisfied when a slot game is executed on the second image display device after winning or passing through the two starting game devices, that is, If a lottery that reduces the first jackpot probability or the second jackpot probability is performed in association with the execution of the slot game, the player can obtain the special game, so that the first picture is also displayed. In order to execute the slot game on the display device or the second image display device, the first starting gaming device or the second starting gaming device tries to win or pass the game ball, and in proportion thereto, a predetermined first gaming condition or first A lottery that lowers the first jackpot probability or the second jackpot probability when the two game conditions are satisfied is also performed, and the lottery result, that is, the first jackpot probability or the second jackpot probability that is reduced by winning the lottery Can be promptly reflected in the slot game executed on the first image display device or the second image display device.

  In addition, when winning a lottery that decreases the rising first big hit probability or the second big hit probability, it is arbitrary from when this reduced first big hit probability or the second big hit probability is set. You may make it reflect from the slot game with respect to the winning or passing of the game ball to the 1st starting gaming machine or the 2nd starting gaming machine which won the lottery which decreases the 1 big hit probability or the 2nd big hit probability. Alternatively, it may be reflected from the slot game next to the slot game. Furthermore, since the timing at which the game ball wins or passes through the first start game device or the second start game device is random, a lottery that uses the random number to reduce the first big hit probability or the second big hit probability is used. If done, the uniformity and irregularity of the lottery result will be ensured.

Therefore, according to the first aspect of the present invention, the lottery probability for reducing the jackpot probability differs depending on whether the slot game is displayed on the first image display device or the second image display device. Therefore, the advantage and disadvantage are determined by which image display device the slot game is displayed on, so that the player has a great interest in the slot game displayed on the image display device, and the game taste is improved. Furthermore, the player can demonstrate the skill of his / her skill and intervene in the game in order to win the game ball to the first start game device or the second start game device that is advantageous to him, and the game ball that falls It is very easy to grasp where the slot game is displayed on the first image display device or the second image display device, that is, the progress of the game. The excitement of the machine will increase and the playability will improve.

The gaming machine according to claim 1 is provided with an incoming prize ratio setting means, the winning percentage setting means, a game ball to winning or passed to a first start game device, winning the second start gaming machine or Set the percentage of game balls that pass. In other words, the winning ratio setting means sets the winning or passing ratio of the game ball falling in the game area to the first starting gaming device and the second starting gaming device. Here, the winning percentage is, for example, one in the first starting gaming device when 100 gaming balls fall in the gaming area and six of them win the first starting gaming device or the second starting gaming device. If five game balls have won or passed through the second starting gaming device, in this case, the winning ratio between the first starting gaming device and the second starting gaming device by the winning ratio setting means is 1: 5. . However, the winning ratio setting by this winning ratio setting means may be an approximate value set by a predetermined setting condition, for example, a three-month test fire test, etc., and therefore is always consistent with an event appearing in a short period of time. is not.

The aspect of the winning ratio setting means is not particularly limited, and examples thereof include a large number of game nails installed in the game board and a ball guidance device provided in the game board. Alternatively, the percentage of game balls that win or pass through the first start game apparatus or the second start game apparatus may be set by guiding the game balls with a ball guiding apparatus. Accordingly, in the invention of claim 1, it is possible to arbitrarily set the winning or passing rate of game balls to Profit degree (advantages and disadvantages) of different first start gaming device or the second start-up game apparatus for Yu technique's, As a result, the degree of freedom in designing the gaming machine can be improved and the game taste can be easily improved.

Here, the winning ratio setting by the winning ratio setting means may be performed as follows. That is, in the gaming machine according to claim 1 , it is assumed that the first lottery probability is lower than the second lottery probability, and the winning percentage setting means is the percentage of game balls that win or pass the first starting gaming machine. Is set lower than the proportion of game balls winning or passing through the second starting gaming machine. For example, as the setting of the winning ratio by the winning ratio setting means according to the first aspect of the present invention, the winning ratio of 1 (first starting gaming machine) to 5 (second starting gaming machine) described above is given as an example.

That is, the winning or passing of the game ball to the first starting gaming device, which is advantageous to the player, is made more difficult than the winning or passing of the game ball to the second starting gaming device. Accordingly, in the invention of claim 1, Yu technique person, in order to win or pass through the game ball to the first start-up game apparatus hardly ball entrance can be technical intervene in the game to demonstrate its workmanship maximize At the same time, he was anxious about the whereabouts of the game ball falling in the game area, and as a result, the interest of the game machine greatly increased. In particular, the player can obtain great joy and satisfaction when a game ball wins or passes through the first starting gaming machine.

If the first lottery probability is lower than the second lottery probability and the winning or passing of the game ball to the first starting gaming device is more difficult than the second starting gaming device, It may be as follows. That is, in the gaming machine according to claim 3, the large hit probability lifting means, the first jackpot probability related to the slot game executed in the first image display apparatus, a slot to be executed by the second image display device so as to increase higher than the second jackpot probability related to the game, the gaming machine according to claim 4, special game is generated when the big hit symbol is determined displayed in the first image display device the 1 special game and a second special game that is generated when the big win symbol is confirmed and displayed on the second image display device, and the content of the special game generated by the special game generating means is more than that of the second special game. It is more advantageous for the player in the first special game, that is, the player who wins the big hit with the first image display device than the second image display device.

In addition, although various things can be considered as what makes the content of a special game advantageous or disadvantageous for a player, it is good to do this as follows. That is, the conversion control that is advantageous to the player of the first variable winning device and the second variable winning device is, in other words, the first variable winning device and the second special game that are controlled to be converted when the first special game occurs. A predetermined mode of the second variable winning device that is controlled to be converted when the game occurs is that the winning opening of the game ball is opened or enlarged, and the first variable winning device has its opening or expansion conversion time, opening Alternatively, the number of expansion conversions (for example, the so-called number of rounds), the specified number of game balls for opening or one expansion conversion, and / or the number of prize balls to be paid out for a single game ball is more than that of the second variable winning device. It is advantageous for the person. That is, the first special game has more game balls that the player can acquire than the second special game.

Such In the present invention of claim 3 of the structure in addition to the effect of the invention of claim 1, The invention of claim 4 the effect of the invention according to claim 1 or claim 3, the second start-up game for Yu technique's It is very advantageous to win the game ball in the first starting game device rather than the device (the first special game is better than the second special game), and the player desperately uses his skill to play the game. An attempt is made to win or pass the ball to the first starting gaming machine that is difficult to enter, and as a result, the effect of the invention of claim 1 can be further remarkably enhanced, and the game performance is greatly improved.

Further, the gaming machine according to claim 5 is the gaming machine according to any one of claims 1 to 4 , wherein each of the gaming machines is a lottery probability that decreases the rising first big hit probability or the second big hit probability. The different first lottery probabilities and second lottery probabilities are exchanged and applied based on the establishment of a predetermined third game condition.

Thus, according to the invention of claim 5 having such a structure, in addition to the effect of any one of the claims 1 to 4, the player first lottery probability predetermined third game condition is satisfied And the second lottery probability are exchanged at positions of the first starting gaming device and the second starting gaming device in order to win the game ball to the first starting gaming device or the second starting gaming device advantageous to the player. Accordingly, it is necessary to adjust the launch intensity of the game ball fired from the hitting ball launching device in a timely manner, that is, it is possible to intervene in the game by demonstrating its own skill, and as a result, the game taste is improved. To do. Furthermore, when the predetermined third game condition is established and the first lottery probability and the second lottery probability are exchanged in the case of the invention of claim 1 , the second lottery probability is lower than the first lottery probability. In addition, the winning or passing of the game ball to the second starting gaming device is easy, that is, the gaming state is changed advantageously for the player, and as a result, the gaming preference is improved.

Here, various establishments of the predetermined third game condition are conceivable, but this may be as follows. That is, in the gaming machine according to claim 6 , in the gaming machine according to claim 5 , the predetermined third gaming condition is established when a predetermined variation pattern or character is displayed in the slot game. In this case, the slot game related to the predetermined variation pattern or character may be displayed on either the first image display device or the second image display device, and the predetermined third game condition may be satisfied. A predetermined third game condition may be satisfied when the image is displayed only on the display device or only on the second image display device. Further, according to claim 1 , as a necessary condition for satisfying the predetermined third game condition, only when the first big hit probability or / and the second big hit probability are increased and the big hit probability decreasing lottery means is executed, The third game condition may be established. Therefore, according to the invention of claim 6 having such a configuration, in addition to the effect of the invention of claim 5 , the player is glad about the fluctuation pattern and the character displayed with further interest in the slot game. .

Further, the gaming machine according to claim 7 is the gaming machine according to any one of claims 1 to 6 , further comprising a probability setting means, and according to an operation from outside the gaming machine by the probability setting means. The first lottery probability and the second lottery probability of the big hit probability decreasing lottery means can be set. Thus, according to the invention of claim 7 having such a structure, in addition to the effect of any one of the claims 1 to 6, the first lottery probability and the second lottery jackpot probability decreases selecting means by probability setting unit If the probability can be set, the operating profit can be easily adjusted for the game hall and the game content can be easily changed. As a result, the gaming machine is easy to use for the game hall.

Is connected.

  Furthermore, the payout control circuit 40 and the display control circuit 111 are connected to the output circuit 110. The payout control circuit 40 includes a payout control CPU (not shown), a RAM having a storage area for storing the work area of the payout control CPU, the number of prize balls corresponding to each prize ball command, and the like. And a ROM in which control data, a control program for paying out a prize ball, and the like are stored. The payout control circuit 40 drives and controls the prize ball payout device 41 according to the prize ball command instructed from the CPU 102 of the main control circuit 44, and performs prize ball payout control. In addition, the payout control circuit 40 is connected to a hitting ball launching device 43 for emitting a pachinko ball toward the game area 5 via the launching control circuit 42. And control.

  Next, the display control circuit 111 will be described with reference to FIG. As shown in FIG. 4, the display control circuit 111 receives a special symbol display device 6a, a control signal such as a one-way strobe signal or a display control command signal from the output circuit 110 of the main control circuit 44. Display control for image processing related to two-dimensional or three-dimensional scroll display displayed on the image display units 30a and 30b of 6b is executed, and image data related to the big hit effect image is output. Therefore, the display control circuit 111 includes a CPU 140, a RAM 141, a ROM 142, a VDP 143, a VRAM (video RAM) 144, a character ROM 145, an input interface 146, a reset circuit 147, an oscillation circuit 148, and a timing controller. 149 and LCD drive circuits 150a and 150b.

  The input interface 146 is provided with a buffer circuit (not shown) composed of, for example, a transistor array whose input terminal is connected to a power source via a resistor. The strobe signal input from the main control circuit 44 and the display control command are provided. The signal is output to an INT terminal (not shown) of the CPU 140. Thus, only signal input from the main control circuit 44 to the display control circuit 111 is permitted, and signal output from the display control circuit 111 to the main control circuit 44 is prohibited. This display control command will be described later. The oscillation circuit 148 is a circuit that outputs a reference clock signal to the CPU 140 and the VDP 143, and the reset circuit 147 is a circuit that outputs a reset signal for resetting the CPU 140 and the VDP 143. The CPU 140 and the VDP 143 divide the reference clock signal from the oscillation circuit 148 to generate an internal clock signal, and operate based on the internal clock signal.

  The ROM 142 is a semiconductor memory that stores a display control program executed by the CPU 140, and the RAM 141 is a semiconductor memory that is used as a work area such as a work area or a stack area of the display control program executed by the CPU 140. The CPU 140 is a central processing unit that executes a display control program. When a strobe signal is input from the input interface 146, the CPU 140 recognizes a display control command signal and controls the display data from the ROM 142 using the RAM 141 as a work area. 2D symbol display information, animation character screen information, background screen information, 3D image information (object) coordinate calculation (geometry calculation) and other image data calculations and drawing commands are created. The calculation result of the data and the created drawing command are stored in the RAM 141 and output to the VDP 143 as a control signal.

  Specific examples of the drawing command include an attribute command, a sprite command, a spline command, a polygon display command, a texture mapping command, and the like.

  The character ROM 145 is constituted by, for example, a flash ROM or the like, and is a semiconductor memory in which image data such as two-dimensional data such as a character, a pattern, a background, and a moving image character, or three-dimensional data such as object data and texture data is stored. The VRAM 144 is a frame buffer memory for temporarily storing and developing image data processed by the VDP 143. The VDP 143 generates image data such as a variable display and a jackpot effect image displayed on the image display units 30a and 30b of the special symbol display devices 6a and 6b based on a control signal from the CPU 140, and is independent of the CPU 140. It has a dimensional address space, and VRAM 144 is mapped there. The memory area of the VRAM 144 is divided into a special symbol display device 6a and a special symbol display device 6b, and the CPU 140 is based on an identifier given to a display control command signal from the main control circuit 44 described later. In response to an instruction from VDP 143, VDP 143 maps the generated image data to the divided memory areas of VRAM 144.

  The VDP 143 includes a timing controller 149, and supplies the image data developed in the divided memory area of the VRAM 144 to the corresponding LCD driving circuits 150a and 150b at regular intervals. That is, the timing controller 149 is based on the reference clock signal from the oscillation circuit 148 and the reset signal from the reset circuit 147, and the synchronization signals (horizontal synchronization signal, vertical synchronization signal, clock signal) supplied to the LCD drive circuits 150a and 150b. The LCD drive circuits 150a and 150b convert the image data supplied from the VDP 143 into a video signal composed of a color signal and a luminance signal, and the waveform of the video signal is displayed as a special symbol as an LCD. Amplitude adjustment, gamma correction, contrast, brightness adjustment, etc. are performed by shaping into a waveform suitable for the devices 6a and 6b, and output to the special symbol display devices 6a and 6b.

  Here, the LCD drive circuits 150a and 150b according to the present embodiment output a video signal conforming to the NTSC system, and a horizontal synchronizing signal (horizontal blanking) is output every 63.5 μsec. The vertical synchronization signal (vertical blanking) is output every 1/30 seconds (non-interlace) (however, in the case of interlace, the vertical synchronization signal is output every 1/60 seconds). In the present embodiment, only the case of non-interlace will be described hereinafter).

  That is, the VDP 143 sequentially supplies the image data developed in the VRAM 144 to the LCD drive circuits 150a and 150b based on the internal clock signal every time the vertical synchronization signal is input from the timing controller 149 (every 1/30 seconds). The LCD drive circuits 150a and 150b convert the supplied image data into a video signal and shape the waveform, and the waveform-shaped video signal is converted into one frame image based on the horizontal synchronization signal by the special symbol display devices 6a and 6b. The image is displayed on the image display units 30a and 30b. The LCD drive circuits 150a and 150b switch the image of one frame displayed on the image display units 30a and 30b of the special symbol display devices 6a and 6b every time a vertical synchronization signal is input (every 1/30 seconds), Thereby, a moving image such as a scroll display or a reach action as a variable display is displayed. The VDP 143 outputs an interrupt signal to the INT terminal (not shown) of the CPU 140 every time a vertical synchronization signal is received from the timing controller 149 (every 1/30 seconds). By receiving this interrupt signal, the CPU 140 executes display control for creating the next one-frame image based on the internal clock signal.

Although the above-described RAM 141 is externally attached to the CPU 140, this is not limited and may be provided in the CPU 140.
Further, as shown in FIG. 4, the main control circuit 44 has a RAM backup 130 circuit that can retain the stored contents of the RAM 104 even when the power is turned off. A test terminal 131 for testing the contents of 44, for example, a connector is also provided.

  Thus, if the RAM 104 of the main control circuit 44 has a backup function that can retain the stored contents even when the power is turned off, for example, lightning occurs nearby and a surge current is generated in the gaming machine 1. Even if the gaming machine 1 is suddenly shut down due to intrusion etc., all the data related to the game stored in the RAM 104 of the main control circuit 44 is maintained, so when the power of the gaming machine 1 is restored , The game can continue to resume from the previous gaming state, and the game arcade can provide a fair game to the player, while the player may be powered off even if the power is interrupted, for example, in an advantageous gaming state. After returning, it becomes possible to continue the advantageous gaming state, so that an unexpected disadvantage can be avoided. In addition to the RAM 104 of the main control circuit 44, this backup function may be provided in the RAM of other control circuits such as the RAM of the payout control circuit 40 that controls the payout of prize balls.

  Further, the control signal (strobe signal, command signal, etc.) is unidirectionally communicated from the CPU 102 of the main control circuit 44 to the display control circuit 111, that is, by eliminating the input from the display control circuit 111 to the main control circuit 44. The number of inputs to the main control circuit 44 that controls the main control of the entire gaming machine 1 can be reduced, and illegal signal inputs to the main control circuit 44 can be eliminated as much as possible, and the game field can provide appropriate games to the player. At the same time, it is possible to simplify the circuit configuration and program related to the communication between the two, which facilitates development and production of the gaming machine 1 and leads to cost reduction. In addition to the display control circuit 111, the one-way communication from the CPU 102 of the main control circuit 44 is also performed to other control circuits such as the payout control circuit 40 for paying out the prize balls shown in FIG. ing.

  When the substrate on which the main control circuit 44 and the payout control circuit 40 are formed is stored in the substrate BOX, a so-called caulking structure in which the substrate BOX is sealed with a predetermined means so as to leave a trace of opening the substrate BOX is left. It is desirable to adopt. As a result, fraud to the main control circuit 44 and the payout control circuit 40 can be eliminated. In addition, the normal symbol display devices 18a and 18b, the game state display devices 32a, 32b, 33a and 33b, the lamp control circuit 37 and the sound control circuit 38 which are directly connected to the output circuit 110 of the main control circuit 44 are the display control circuit 111 or The payout control circuit 40 may be connected. Furthermore, the hitting operation handle switch 119 and the hitting operation stop switch 120 connected to the input circuit 101 may be directly connected to the launch control circuit 42 or the payout control circuit 40. These may be appropriately designed according to the functions and arrangement of various devices constituting the gaming machine control device 100, the processing speed of each CPU, the capacity of a storage device such as ROM, RAM, and the like.

  In the gaming machine 1 configured as described above, the gaming machine control device 100 performs overall control of the gaming machine 1 by executing the processing shown in the flowcharts of FIG. Various images corresponding thereto are displayed on the special symbol display devices 6a, 6b and the like.

  FIG. 5 is a flowchart showing a main game process (main routine) executed by the CPU 102 of the main control circuit 44. Immediately after the power is turned on, the CPU 102 performs initialization processing (step S10), and initializes flags, registers, and storage areas necessary for stack setting and the following processing. When the CPU 102 finishes the initialization process in step S10, the process proceeds to the random number update process in step S20. The CPU 102 executes a main routine (each program stored in the ROM 103 of the main control circuit 44), that is, each process of Step S20 to Step S60 described below, every reset interrupt (2 msec).

  FIG. 6 is a list of random numbers handled by the main control circuit 44. In the main control circuit 44, as shown in FIG. 6, various counters C1 to C12 (random numbers 1 to 12) are set as random numbers for setting the game mode at random. CPU102 updates the value regarding each counter C1-C12 by the random number update process of step S20. The counters C1 to C12 shown below are provided in order to always create an invariant complete probability. For example, the counter C1 to C12 creates a probability that changes every time, for example, a forklift that does not return the lottery. is not.

  The jackpot determination counter C1 (random numbers 1, 0 to 314) is a random number counter that draws whether or not a special symbol combination is a jackpot (details will be described later. ), Starting from 0 when the power is turned on, and incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C1 becomes 315, it is rewritten to 0.

  Random number counter for determining the stop symbol of a special symbol is a random number that creates an off symbol other than the jackpot symbol, which will be described later, as a special symbol combination (including a case where the symbol is disengaged after reaching reach; Counters for left stop symbol determination C2 (random numbers 2, 0 to 13), middle stop symbol determination counter C3 (random numbers 3, 0 to 13), right stop symbol determination counter C4 (random numbers 4, 0 to 13) 13) is provided.

  The left stop symbol determination counter C2 is a counter used for creating a symbol for the left symbol, starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (2 msec). However, when the random number counter C2 becomes 14, it is rewritten to 0. The middle stop symbol determination counter C3 is a counter used to create a middle symbol, starts from 0 when the power is turned on, and is incremented (added by 1) each time the left stop symbol determination counter C2 is set to zero. The However, when the random number counter C3 becomes 14, it is rewritten to 0. The right stop symbol determination counter C4 is a counter used to create a right symbol design, and starts from 0 when the power is turned on. The However, when this random number counter C4 becomes 14, it is rewritten to 0. By doing so, it becomes possible to prevent the left, middle and right symbols from being synchronized.

  The reach determination counter C5 (random numbers 5, 0 to 11) is a random number counter (to be described later in detail, the reach is 3 when the special symbol combination is used as an out-of-band design). The probability is 1/12), which starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (2 msec). However, when the random number counter C5 becomes 12, it is rewritten to 0.

  The reach symbol mode determination counter C6 (random numbers 6, 0 to 62) indicates that the special symbol that the middle symbol display portions 9a and 9b stop when the combination of the special symbols is out of reach, the left symbol display portions 8a and 8b. The right symbol display units 10a and 10b are set to plus or minus 1 of the same special symbol to be stopped (to be described later, in this embodiment, the left symbol display units 8a and 8b, the middle symbol display units 9a and 9b, and the right symbol display unit Each special symbol displayed on 10a and 10b is scroll-displayed in the order of 1 to 14, for example, the special symbols on which the left symbol display units 8a and 8b and the right symbol display units 10a and 10b are stopped are three. Is set to 4 (plus 1) or 2 (minus 1), and hereinafter, the middle symbol display portions 9a and 9b are stopped. Random number counter that draws whether another symbol is also called plus or minus 1 symbol (explained in detail later, the case of 0 to 19 is the reach of plus or minus 1 symbol, probability 20/63) It starts from 0 and is incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C6 becomes 63, it is rewritten to 0.

  The jackpot symbol determination counter C7 (random numbers 7, 0 to 13) is a random number counter that creates a jackpot symbol as a combination of special symbols. Added). However, when the random number counter C7 becomes 14, it is rewritten to 0.

  The variation pattern determination counter C8 (random numbers 8, 0 to 51) is a random number counter for lottery of which variation pattern is adopted as the reach action described above, for example, when a special symbol combination is a big hit or out of reach. Thus, it starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C8 becomes 52, it is rewritten to 0.

  The probability variation fall determination counter C9 (random numbers 9, 0 to 199) is a case where a specific big hit symbol, which will be described later, is confirmed and displayed as a big hit symbol, and the big hit probability is increased (the probability is 1/63, which will be described in detail later). In addition, a random number counter (later referred to simply as a falling lottery) for determining whether or not this rising jackpot probability is dropped to the normal jackpot probability in the slot game of each special symbol display device 6a or 6b As will be described in detail, the case of 55, 155 is a fall, probability 1/100), which starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C9 becomes 200, it is rewritten to 0.

  The probability variation fall determination counter C10 (random number 10, 0 to 199) is the same random number counter as the probability variation fall determination counter C9 (described in detail later, in the case of 55, fall, probability 1/200), and the power is turned on. It starts from 0 and is incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C10 becomes 200, it is rewritten to 0.

  In other words, the probabilities of the probability variation fall determination counters C9 and C10 are different, and the probability variation fall determination counter C9 has a higher probability of falling than the probability variation fall determination counter C10. When the jackpot probability is rising, the probability variation fall determination counters C9 and C10 are applied to either of the slot games of the special symbol display devices 6a and 6b, respectively. When the counter C9 is applied to the slot game of the special symbol display device 6a, the probability variation fall determination counter C10 is always applied to the slot game of the special symbol display device 6b. Therefore, for the player, the slot game to which the probability change fall determination counter C10 is applied is more advantageous than the slot game to which the probability change fall determination counter C9 is applied.

  The hit determination counter C11 (random numbers 11, 0 to 30) is a random number counter that draws a lottery to determine whether or not to win a normal symbol (details will be described later. ) And starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (2 msec). However, when this random number counter C11 becomes 31, it is rewritten to 0.

  The off symbol determination counter C12 (random numbers 12, 0 to 8) is a counter used to create a normal symbol off symbol, starts from 0 when the power is turned on, and increments (adds 1) every reset interrupt (2 msec). Is done. However, when this random number counter C12 becomes 9, it is rewritten to 0.

  Returning to FIG. 5, when the CPU 102 finishes the random number update process in step S <b> 20, the CPU 102 proceeds to the normal game process in step S <b> 30. FIG. 7 is a flowchart showing the normal game process (step S30). The normal game process includes an operation gate 19a passing process in step S450, a normal symbol display device 18a game process in step S500, an operation gate 19b passing process in step S540, and a normal symbol display device 18b game process in step S570. First, the operation gate 19a passing process in step S450 will be described.

  FIG. 8 is a flowchart showing the operation gate 19a passage processing (step S450). When the operation gate 19a passage process is started, the CPU 102 determines whether or not the game ball that has passed the normal symbol operation gate 19a is detected (operation signal input to the operation gate detection sensor 121a) (step S452). If no game ball is detected (NO in step S452), the operation gate 19a passing process is terminated, and the process proceeds to the normal symbol display device 18a game process (FIG. 10) in step S500. On the other hand, when a game ball is detected (YES in step S452), CPU 102 proceeds to the process in step S454 and determines whether the value of counter Aa is less than 5.

  This counter Aa is a counter set in the main control circuit 44 to store the number of reserved memories (the number of retained balls passed) of the hold LED 26 (see FIG. 2), and the operation gate detection sensor 121a is a normal symbol operation gate 19a. When a game ball passing through is detected, the minimum value is changed from 0 to a maximum value of 5. When the power is turned on, the value is initialized and a minimum value of 0 is set.

  If NO in step S454, that is, if the counter Aa is a value of 5 or more, the CPU 102 ends the operation gate 19a passing process. On the other hand, if YES in step S454, that is, if the counter Aa is a value from 0 to 4, the process proceeds to step S456, and the CPU 102 increments the value of the counter Aa (add 1) based on the operation signal described above. Then, the process proceeds to step S458 to execute a random number acquisition process. When the CPU 102 proceeds to the random number acquisition process in step S458, the CPU 102 acquires the current values of the counters C11 and C12 described above and stores them in the acquired numerical value storage area of the RAM 104, respectively. When the random number acquisition process in step S458 ends, the CPU 102 proceeds to the hold LED 26 lighting control process in step S464.

  FIG. 9 is a flowchart showing the hold LED 26 lighting control process (step S464). When the hold LED 26 lighting control process is executed, the CPU 102 first determines in the process of step S466 whether or not the value of the counter Aa is 2 or more, and if not (2 in step S466), that is, When the value of the counter Aa is 0 or 1, the hold LED 26 lighting control process is ended, and the normal symbol display device 18a game process of step S500 is executed. On the other hand, if YES in the process of step S466, that is, if the value of the counter Aa is 2 or more, the process proceeds to step S468, and the CPU 102 has four hold LEDs 26a, 26b, 26c, and 26d (see FIG. 2), the lamp control circuit 37 is driven to light up, and the hold LED 26 lighting control process is terminated.

  FIG. 10 is a flowchart showing the normal symbol display device 18a game process (step S500). When the normal symbol display device 18a game process is executed, the CPU 102 first determines whether or not the value of the counter Aa is 1 or more in the process of step S501 (NO in step S501). That is, if the value of the counter A is 0, the normal symbol display device 18a game process is terminated, and the process proceeds to the operation gate 19b passing process in step S540 of the normal game process (FIG. 7). On the other hand, when the value of the counter Aa is 1 or more in the process of step S501 (YES in step S501), the CPU 102 proceeds to the process of step S502 and sets a value in the hit flag F4a.

  The main control circuit 44 is set with a hit flag F4a (see FIG. 22 described later), and the hit flag F4a is set to 0 when the power is turned on. In the random number acquisition process in step S458 described above, when the acquired numerical value of the hit determination counter C11 (random numbers 11, 0 to 30) is 0 to 9, the CPU 102 sets 1 to the hit flag F4a. If the acquired numerical value of the hit determination counter C11 is not 0 to 9, that is, 10 to 30, the hit flag F4a remains 0. Therefore, the hit probability in this case is 10/31, and the probability of loss is 20/31. When the CPU 102 finishes the process of setting the hit flag F4a in step S502, the CPU 102 proceeds to the normal symbol determination process in step S503.

  FIG. 11 shows the relationship between the random number value of the off symbol determination counter C12 (0 to 8) and the normal symbol (one-digit normal symbol displayed on the normal symbol display devices 18a and 18b composed of 7-segment LEDs). It is explanatory drawing shown. When the CPU 102 proceeds to the normal symbol determination process in step S503, the CPU 102 determines the normal symbol that is fixedly displayed on the normal symbol display device 18a. If the winning flag F4a is set to 1 (if it is a winning), the CPU 102 determines the number symbol “7” as the winning symbol. On the other hand, if 0 is set in the hit flag F4a, an error symbol corresponding to the acquired numerical value of the error symbol determination counter C12 (0 to 8) shown in FIG. 11 (for example, “2” if C12 = 2) is displayed. The normal symbol determination process in step S503 is terminated, and the process proceeds to the normal symbol control process in step S504.

  FIG. 12 is a flowchart showing the normal symbol control process (step S504). When this normal symbol control process is executed, the CPU 102 first executes a normal symbol variation display process in the process of step S506. In the normal symbol variation display process in step S506, the CPU 102 controls a driver circuit (not shown) to variably display the ordinary symbol on the ordinary symbol display device 18a. Then, the CPU 102 proceeds to the process of step S508 to determine whether or not the preset normal symbol variation time t has timed up (t = 0), and NO in the process of step S508, that is, normal If it is determined that the symbol variation time t has not expired, the CPU 102 ends the normal symbol control process (step S504), returns to the normal symbol game process (FIG. 10), and proceeds to the process of step S512. Transition. On the other hand, if YES in the process of step S508, that is, if it is determined that the normal symbol variation time t has timed up, the process proceeds to the normal symbol fixed display process of step S510.

  In step S510, the CPU 102 controls the driver circuit (not shown) to display the variable symbol in the normal symbol display device 18a so as to confirm and display the normal symbol determined in the normal symbol determination process in step S503. The process of stopping the normal symbol is executed. When the normal symbol is confirmed and displayed on the normal symbol display device 18a in the process of step S510, the CPU 102 ends the normal symbol control process.

  When the process proceeds to step S512, the CPU 102 determines whether or not the normal symbol is fixedly displayed on the normal symbol display device 18a. If the normal symbol is not fixedly displayed (NO in step S512), the normal symbol is displayed. The symbol game process (step S500) is terminated. On the other hand, when it is determined in the process of step S512 that the normal symbol is confirmed and displayed on the normal symbol display device 18a (YES in step S512), the CPU 102 proceeds to the process of step S514. When the process proceeds to step S514, the CPU 102 determines whether the value of the hit flag F4a is 1 or not (YES in step S514), the process proceeds to step S516 and is shown in FIG. A start winning opening 11a opening process is executed.

  FIG. 13 is a flowchart showing the start winning opening 11a opening process (step S516). When the start winning opening 11a opening process is executed, the CPU 102 first drives and controls the solenoid 107a to open the blades of the starting winning opening (electric tulip) 11a in the process of step S518. Then, the process proceeds to step S520, and the CPU 102 determines whether or not the set start winning opening opening time ST is up (ST = 0). Therefore, this time ST is the opening time of the start winning opening 11a, that is, the time from when the starting winning opening 11a opens the blade until it closes. The start winning opening opening time ST is set to 0.2 seconds. If NO in the process of step S520, that is, if it is determined that the start winning opening opening time ST has not timed up, the CPU 102 proceeds to the process of step S522, and the value of the counter Ga is 6 or more. It is determined whether or not.

  This counter Ga counts the main control circuit 44 in order to count the number of game balls won in the start winning opening 11a until the opened winning opening 11a is closed after the start winning opening releasing time ST elapses. Is counted up when the count switch 123a detects a game ball, and is initialized and set to 0 when the power is turned on.

  If NO in step S522, that is, if the value of the counter Ga is determined to be less than 6, the start winning opening 11a opening process is terminated, and the process proceeds to step S528. On the other hand, when it is determined YES in the process of step S520 or the process of step S522, that is, when it is determined that the start winning opening opening time ST has timed up or when the value of the counter Ga is determined to be 6 or more, In step S524, the CPU 102 controls the solenoid 107a to close the blades of the start winning port 11a. Then, the process proceeds to step S525, and the CPU 102 sets the value of the counter Ga to 0, proceeds to the process in step S526, sets the value of the winning flag F4a to 0, and opens the start winning opening 11a. The process (step S516) ends, and the process proceeds to step S528.

  When the process proceeds to step S528, the CPU 102 determines whether or not the value of the winning flag F4a is 0, that is, whether or not the predetermined start winning opening 11a opening process (step S516) is all finished, and the winning flag F4a is set. When the value is not 0 (NO in step S528), that is, in the case of 1, it is determined that the predetermined start winning opening 11a opening process has not been completed, and this normal symbol game process (step S500) is ended. . On the other hand, when the value of winning flag F4a is 0 (YES in step S528), CPU 102 determines that all the predetermined start winning opening 11a opening processing has been completed, and proceeds to the processing in step S530. On the other hand, if the value of the hit flag F4a is not 1 in the process of step S514 (NO in step S514), that is, if the value of the hit flag F4a is 0, the CPU 102 proceeds to the process of step S530. . When the process proceeds to step S530, the CPU 102 decrements (subtracts 1) the value of the counter Aa incremented (added by 1) in the process of step S456 described above (FIG. 8), and the process proceeds to step S532. The hold LED 26 extinguishing control process is executed.

  FIG. 14 is a flowchart showing the hold LED 26 extinguishing control process (step S532). When the hold LED 26 extinguishing control process is executed, the CPU 102 first determines whether or not the value of the counter Aa is 1 or more in the process of step S534, and if the value of the counter Aa is not 1 or more (in step S534) NO), that is, if the value of the counter Aa is 0, the hold LED 26 extinguishing control process is terminated, the normal symbol display device 18a game process (step S500) is terminated, and the normal game process (FIG. 7) is stepped. The process proceeds to the operation gate 19b passing process of S540. On the other hand, if YES in step S534, that is, if the value of the counter Aa is 1 or more, the process proceeds to step S536, and the CPU 102 selects one of the four hold LEDs 26a, 26b, 26c, and 26d. Then, the lamp control circuit 37 is driven to turn off the corresponding one, and the hold LED 26 turn-off control process is finished.

  Returning to FIG. 7, when the normal symbol display device 18a game process (step S500) is completed, the CPU 102 sequentially executes the operation gate 19b passage process in step S540 and the normal symbol display device 18b game process in step S570. The operation gate 19b passage processing (step S540) is the above-described operation gate 19a passage processing of step S450, and the normal symbol display device 18b game processing (step S570) is the above-described normal symbol display device 18a game processing of step S500. The same is true for the starting gate 11a, the operating gate 19a, the holding LED 26 (holding LEDs 26a, 26b, 26c, 26d), the counter Aa in the passing process (step S450) and the normal symbol display device 18a game process (step S500). , Hit flag F4 And the counter Ga can be read as the start winning opening 11b, the operation gate 19b, the holding LED 31 (holding LEDs 31a, 31b, 31c, 31d), the counter Ab, the winning flag F4b, and the counter Gb, respectively, and the description is omitted here. To do.

  Then, when the normal symbol display device 18b game process in step S570 is completed, the normal game process (step S30) is terminated, and the processing returns to FIG. FIG. 15 is a flowchart showing the special game process. The special game process includes a start winning opening winning process in step S200 and a special symbol game process in step S300. First, the starting winning opening winning process in step S200 will be described.

  FIG. 16 is a flowchart showing the start winning opening winning process (step S200). The start winning opening winning process includes a start winning opening 11a winning process in step S201 and a starting winning opening 11b winning process in step S273. First, the start winning opening 11a winning process in step S201 will be described.

  FIG. 17 is a flowchart showing the start winning opening 11a winning process (step S201). When the start winning opening 11a winning process is started, the CPU 102 determines whether or not the game ball that has won the start winning opening 11a has been detected (start signal input from the start winning detection sensor 116a) (step S202). If no game ball has been detected (NO in step S202), the start winning port 11a winning process is terminated, and the process proceeds to the starting winning port 11b winning process in step S273. On the other hand, when a game ball is detected (YES in step S202), the process proceeds to step S204 to determine whether the value of counter Ba is less than 5. This counter Ba is the same as the counter Aa described above, and is a counter set in the main control circuit 44 for storing the number of reserved memories (the number of reserved balls) of the hold LED 25, and the start winning detection sensor 116a is started. When a game ball that has won a prize opening 11a is detected, the game ball is changed from a minimum value 0 to a maximum value 5. When the power is turned on, the value is initialized and a minimum value 0 is set.

  If NO in step S204, that is, if the counter Ba has a value of 5 or more, the start winning port 11a winning process is terminated. On the other hand, if YES in the process of step S204, that is, if the counter Ba has a value of 0 to 4, the process proceeds to step S206, and the CPU 102 increments the value of the counter Ba (add 1) based on the start signal described above. Then, the process proceeds to step S212 to execute a random number acquisition process. When the CPU 102 proceeds to the random number acquisition process in step S212, the CPU 102 acquires the current values of the counters C1, C5, C6, C8, C9, and C10 out of the counters C1 to C12, and acquires the numerical value storage area of the RAM 104. To store each. When the random number acquisition process of step S212 is completed, the CPU 102 proceeds to step S216 and executes the hold LED 25 lighting control process.

  FIG. 18 is a flowchart showing the hold LED 25 lighting control process (step S216). When the hold LED 25 lighting control process is executed, the CPU 102 first determines whether or not the value of the counter Ba is 2 or more in the process of step S218. If it is not 2 or more (NO in step S218), that is, If the value of the counter B is 0 or 1, the hold LED 25 lighting control process is terminated, and the start winning opening 11b winning process of step S273 is executed. On the other hand, if YES in step S218, that is, if the value of the counter B is 2 or more, the process proceeds to step S220, and the CPU 102 selects one of the four hold LEDs 25a, 25b, 25c, and 25d. The corresponding one is driven to light up by driving the lamp control circuit 37, and the hold LED 25 lighting control process (step S216) is terminated.

  When the hold LED 25 lighting control process is completed, the CPU 102 returns to the start winning opening winning process (FIG. 16), and executes the starting winning opening 11b winning process in step S273. The start winning port 11b winning process (step S273) is the same as the starting winning port 11a winning process in step S201 described above, and the starting winning port 11a and the hold LED 25 (hold LED 25a, 25b, 25c, and 25d) and the counter Ba may be read as the start winning opening 11b, the hold LED 29 (hold LEDs 29a, 29b, 29c, and 29d), and the counter Bb, respectively, and the description thereof is omitted here.

  As is clear from the above description, in the start winning port 11a winning process (step S201) and the starting winning port 11b winning process (step S273), a special symbol display is made based on the winning of the game ball in the starting winning port 11a. The display of the slot game is started by the device 6a, and the display of the slot game is started by the special symbol display device 6b based on the winning of the game ball in the start winning opening 11b. Both the symbol display devices 6a and 6b display the slot game simultaneously in parallel, and the lighting control of the holding LEDs 25a, 25b, 25c and 25d and the holding LEDs 29a, 29b, 29c and 29d is also performed in this game. It is controlled based on the mode.

  When the start winning opening 11b winning process in step S273 is completed, the CPU 102 returns to the special game process (FIG. 15), ends the starting winning opening winning process, and executes the special symbol game process in step S300. FIG. 19 is a flowchart showing the special symbol game process (step S300). The special symbol game process includes a special symbol display device 6a game process in step S318 and a special symbol display device 6b game process in step S445. First, the special symbol display device 6a game process in step S318 will be described.

  FIG. 20 is a flowchart showing the special symbol display device 6a game process (step S318). When the special symbol display device 6a game process is executed, the CPU 102 first determines whether or not the value of the counter Ba is 1 or more in the process of step S319. If the value of the counter Ba is not 1 or more (step S319) If NO in S319, that is, if the value of the counter Ba is 0, the special symbol display device 6a game process is terminated and the process proceeds to the special symbol display device 6b game process in step S445. On the other hand, when the value of the counter Ba is 1 or more in the process of step S319 (YES in step S319), the process proceeds to step S320.

  That is, in the process of step S319, the CPU 102 receives a game ball in the start winning opening 11a (except when any of the hold LEDs 25a, 25b, 25c, and 25d is lit), or step S436 described later. In the on-hold LED turn-off control process, it is determined YES when any of the hold LEDs 25a, 25b, 25c, and 25d is turned off, and the game process on and after step S320 related to the special symbol display device 6a is executed.

  In step S320, the CPU 102 executes a probability variation guarantee display process. FIG. 21 is a flowchart showing the probability variation guarantee display process (step S320). When the probability variation guarantee display process is executed, the CPU 102 first sets the probability variation guarantee flag F5a to 1 based on the fact that the big hit probability has increased in the process of step S430 described later in the process of step S619. Determine whether or not. Here, main flags set in the main control circuit 44 will be described with reference to FIG.

  FIG. 22 is a list of main flags in the main control circuit 44. As shown in FIG. 22, there are seven main flags in total, and these flags are set to 0 when the power is turned on. F1a, F1b, F2a, F2b, F3a, and F3b are a big hit flag, a reach flag, and a reach mode flag. Based on the value of the symbol mode determination counter C6, 1 is set when it is determined that the result of the current slot game will be a big hit, reach, plus or minus 1 symbol. F4a and F4b are hit flags, and these flags are set as 1 based on the value of the hit determination counter C10 in the processing of step S502 and the like, as described above.

  F5a and F5b are probability variation guarantee flags, and these flags are set to 1 based on the fact that the jackpot probability has increased in the process of step S430, which will be described later, and then after the jackpot game ends in the process of step S627, etc. When the slot game to be executed is not based on a holding ball before the end of the big hit game, 0 is set, that is, the probability variation guarantee flags F5a and F5b are set after the end of the big hit game with the specific big win symbol described later, A period 1 is set until all the slot games related to the holding balls (related to the special symbol display devices 6a and 6b, each of which is usually up to 4 each) generated before the big hit game is finished, The falling lottery is not executed during this period, and the jackpot probability is guaranteed with a high probability.

  F6 is an exchange flag, and this flag is displayed when step 671 or later to be described later when the reach loss of plus or minus 1 symbols is confirmed and displayed as a result of the slot game when the probability of jackpot rises to a high probability. If the value changes to 1 or 0 in the process of step S677, that is, if the exchange flag F6 is set to 0, the probability of the falling lottery described later is 1/100 on the special symbol display device 6a. When the special symbol display device 6b is 1/200, and the exchange flag F6 is set to 1, the probability of falling lottery is 1/200 for the special symbol display device 6a and 1/100 for the special symbol display device 6b. It becomes. That is, when the value of the exchange flag F6 changes, the probability of the falling lottery of the special symbol display device 6a and the probability of the falling lottery of the special symbol display device 6b are exchanged. For example, 1 is set in the exchange flag F6. If so, the special symbol display device 6a has a lower probability of winning the falling lottery, which is advantageous.

  F7a and F7b are probability variation flags. These flags are set to 1 based on the fact that the big hit probability has increased in the processing of step S428 described later, that is, 1 is set to the probability variation flags F7a and F7b. When it is displayed, it indicates that the big hit probability is high.

  Returning to FIG. 21, if NO in the process of step S619, that is, if the probability variation guarantee flag F5a is set to 0, this probability variation guarantee display process is terminated, and the process proceeds to step S345. On the other hand, if YES in the process of step S619, that is, if the probability variation guarantee flag F5a is set to 1, the process proceeds to the process of step S621, and the CPU 102 after the big hit game in the special symbol display device 6a of this time It is determined whether or not the slot game to be executed is based on a holding ball whose holding LED 25 before the end of the big hit game is lit.

  If YES in the process of step S621, that is, if the slot game executed on the special symbol display device 6a this time is based on the reserved ball before the big hit game ends, the process proceeds to step S623, and the CPU 102 The display control circuit 111 is driven to display “probability change” and “guarantee” on the game state display devices 32a and 32b, respectively. Here, the game state display devices 32a and 32b notify the player that the game state is the normal game state in the initialization process in step S10 described above, and therefore, when the power is turned on, the “normal” and “normal” respectively. Is displayed. Therefore, in the process of step S623, the display of the game state display device 32a is changed from “normal” to “probability” which means that the probability of winning the jackpot has increased to a high probability. ”Is switched to“ guaranteed ”which means that the winning lottery is not performed and the jackpot probability is maintained at a high probability, so that the player is informed accordingly.

  When the processing of step S623 is completed, the CPU 102 proceeds to the processing of step S625, outputs a probability change guarantee effect command to the display control circuit 111, and holds on the special symbol display device 6a before the end of the jackpot game. Directly or indirectly (implicitly) that a lottery lottery is not performed and it is guaranteed that the jackpot probability is maintained at a high probability until the slot game related to the LED 25 holding ball is exhausted. ) Display effect. This probability variation guarantee display will be described in detail later.

  Therefore, by the processing of step S623 and step S625, the player again hits a big hit (so-called so-called "hit" by the holding ball immediately after the big hit game is ended on the special symbol display device 6a in the display of the game state display device 32 and the probability variation guarantee effect display. Since it is possible to recognize or predict that the possibility of becoming a daisy chain is increasing, the gaming property of the gaming machine 1 is improved. When the process of step S625 is completed, the CPU 102 ends the probability variation guarantee display process.

  On the other hand, NO in the process of step S621, that is, if the slot game executed on the special symbol display device 6a this time is not based on the holding ball before the end of the big hit game, in other words, occurred after the big hit game and before the end of the big hit game When all the slot games related to the held ball of the hold LED 25 have been consumed, the process proceeds to step S627, and the CPU 102 sets the probability variation guarantee flag F5a to 0, and proceeds to the process in step S627 for replacement. It is determined whether or not 0 is set in the flag F6. If 0 is set in the exchange flag F6 and YES is determined in step S627, the process proceeds to step S628, and the CPU 102 drives the display control circuit 111 to play the game state display device 32a. “Probability change” is displayed on the game state display device 32b, and “falling probability 1/100” is displayed.

  Here, “probability change” is displayed on the gaming state display device 32a and “guarantee” is displayed on the gaming state display device 33b by the processing of step S623 described above. Therefore, in the processing of step S628, the gaming state display device is displayed. The display of 32a displays “probability change” as it is, and the display of the game state display device 32b changes from “guaranteed” to the special symbol display device 6a, which means that the falling lottery is performed with a probability of 1/100. By switching the display to “probability 1/100”, the player is informed accordingly.

  On the other hand, if the exchange flag F6 is set to 1 and the result of step S627 is NO, the process proceeds to step S629, and the CPU 102 drives the display control circuit 111 to play the game state display device. The display of 32a displays “probability change” as it is, and the display of the game state display device 32b changes from “guaranteed” to “falling probability 1/200” which means that the probability of falling lottery of the special symbol display device 6a has been changed. By switching and displaying, the player is informed accordingly. When the process of step S628 or step S629 is completed, the CPU 102 proceeds to the process of step S631.

  Although the possibility of occurrence is extremely low, if there is no reserved ball related to the special symbol display device 6a before the end of the big hit game after the end of the big hit game, YES in the process of step S621 Therefore, in the processing of step S628, the display of the gaming state display device 32a is changed from “normal” to “probability”, and the display of the gaming state display device 32b is changed from “normal” to “falling probability 1/100”. In the process of S629, the display of the gaming state display device 32a is switched from “normal” to “probability”, and the display of the gaming state display device 32b is switched from “normal” to “falling probability 1/200”.

  Then, when the process proceeds to step S631, the CPU 102 outputs a fall lottery start effect command to the display control circuit 111, and directs the special symbol display device 6a to start the lottery to drop the big hit probability from a high probability. Or indirectly (suggestively) effect display. The falling lottery start effect display will be described in detail later. Therefore, by the processing of step S629 and step S631, the player ends the period in which the big hit probability after the big hit game is guaranteed with a high probability on the display of the game state display device 32 and the falling lottery start effect display. In addition, since the special symbol display device 6a can recognize or predict that the falling lottery starts from the current slot game, the gameability of the gaming machine 1 is improved. When the process of step S631 is completed, the CPU 102 ends the probability variation guarantee display process.

  Returning to FIG. 20, when the probability variation guarantee display process is completed, the CPU 102 proceeds to the process of step S345, and sets values for the big hit flag F1a, the reach flag F2a, and the reach mode flag F3a. In the random number acquisition process in step S212 described above, when the acquired numerical value of the big hit determination counter C (random numbers 1, 0 to 314) is normal (F7a = 0), it is 7, and when the big hit probability is high (F7a = 1) In the case of 7, 33, 77, 111, 222, 1 is set to the big hit flag F1a. If the acquired value of the big hit determination counter C1 is other than that, the big hit flag F1a remains zero. Therefore, in the special symbol display device 6a, the jackpot probability at normal time is 1/315 (probability of loss is 314/315), and the jackpot probability at high probability is 5/315 (probability of loss is 310/315).

  Further, when the obtained numerical value of the reach determination counter C5 (random numbers 5, 0 to 11) is 3, 1 is set to the reach flag F2a. It should be noted that the reach flag F2a remains 0 when the obtained numerical value of the reach determination counter C5 is not 3, that is, 0-2 and 4-11. Accordingly, the probability of detachment relating to the special symbol display device 6a is 1/12, and the probability of detachment of non-reach is 11/12.

  Further, when the numerical value of the reach symbol mode determination counter C6 (random numbers 6, 0 to 62) is 0 to 19, 1 is set to the reach mode flag F3a. In addition, when the acquisition numerical value of the reach symbol mode determination counter C6 is 20 to 62, the reach mode flag F3a remains 0. Accordingly, the probability of reach divergence in which the middle symbol display unit 9 related to the special symbol display device 6a becomes plus / minus one symbol is 20/63, and the probability of reach divergence in which the middle symbol display unit 9 is other than plus / minus one symbol is 43/63. 63. CPU102 transfers to the special symbol determination process of step S346, after complete | finishing the process of step S345.

  FIG. 23 is a flowchart showing the special symbol determination process (step S346). When the special symbol determination process is executed, the CPU 102 determines whether or not the value of the big hit flag F1a is 0 in step S347. If the value of the big hit flag F1a is not 0 (NO in step S347), that is, if the value of the big hit flag F1a is 1, the process proceeds to step S353 and is created in a predetermined storage area of the RAM 104. Corresponding jackpot symbol data is acquired from the jackpot symbol storage buffer in which the jackpot symbol data is stored.

  24 and 25, the left stop symbol determination counter C2 (random numbers 2, 0 to 13), the middle stop symbol determination counter C3 (random numbers 3, 0 to 13), and the right stop symbol determination counter A special symbol (left symbol display unit 8, middle symbol display unit) as an off symbol or jackpot symbol based on the random number values of C4 (random numbers 4, 0 to 13) and jackpot symbol determination counter C7 (random numbers 7, 0 to 13) 9. A case where each special symbol displayed on the right symbol display unit 10 is created will be described. 24 and 25 show the relationship between the random numbers of the stop symbol determination counters C2, C3, C4 and the jackpot symbol determination counter C7 and the special symbols, and the special symbols are the stop symbol determination counters C2, C3, C4 and It is explanatory drawing which shows the process produced based on the random value of the big hit symbol determination counter C7. First, with reference to FIGS. 24 (A), (B), (C) and FIG. 25 (A), description will be made of a case where a special symbol combination (including reach deviation) is created as a special symbol combination.

  The left stop symbol determination counter C2 (random numbers 2, 0 to 13), the middle stop symbol determination counter C3 (random numbers 3, 0 to 13) and the right stop symbol determination counter C4 (random numbers 4, 0 to 13) are respectively 24, (A), (B), and (C), the special symbols 1 to 14 correspond to the random numbers 0 to 13 and are counted up as described in the random number update process in step S20. However, the random number update process in step S60 shown in FIG. 5 described later in detail performs a process that continues to be updated during the remaining time of the main game process. Therefore, each random value is a random value every 2 msec. As a result, each special symbol corresponding to the random value is also created as random data every 2 msec.

  As shown in FIG. 25A, the data of each special symbol created to be displayed on the left symbol display unit 8, the middle symbol display unit 9, and the right symbol display unit 10 every 2 msec Are stored in a predetermined symbol storage buffer created in the storage area. Here, as the special symbol combination, when the data of the reach out of which the middle symbol display unit 9 becomes plus or minus 1 symbol is created, the reach symbol storing buffer of plus or minus 1 symbol is used as the special symbol combination, When the data of the reach out of which the middle symbol display unit 9 is other than the plus / minus 1 symbol is created, the data of the out of the reach which does not become the reach as the combination of the special symbol is stored in the reach symbol storing buffer other than the plus / minus 1 symbol. When created, each of them is stored in the errant symbol storage buffer which does not become reach, and when the jackpot symbol data shown in FIG. 24D is created as a special symbol combination, , Not to be remembered. In FIG. 25 (A), “1, 2, 1” is a combination of special symbols that are out of reach where the middle symbol display portion 9 becomes plus or minus one symbol, and the middle symbol display portion 9 is other than plus or minus one symbol. As an example, “5, 8, 5” is shown as a combination of the special symbols that are not reachable, and “5, 5, 1” is shown as a combination of the special symbols that are not reach.

  Next, the case where a big hit symbol is created as a combination of special symbols will be described with reference to FIGS. 24 (D) and 25 (B). The jackpot symbol determination counter C7 (random numbers 7, 0 to 13) is, as shown in FIG. 24D, jackpot symbols “1, 1, 1” to “14, 14 and 14 ”, and is counted up as described in the random number update process in step S20. The main number is updated by the random number update process in step S60 shown in FIG. Since the process continues to be updated during the remaining time of the game process, the random value takes a random value every 2 msec, and as a result, the jackpot symbol corresponding to the random value is also created as random data every 2 msec. .

  As shown in FIG. 25 (B), the jackpot symbol data created to be displayed on the left symbol display unit 8, the middle symbol display unit 9, and the right symbol display unit 10 every 2 msec is stored in a predetermined memory of the RAM 104. The jackpot symbol storage buffer created in the area is stored while being rewritten. Note that, in FIG. 25 (B), a jackpot symbol “5, 5, 5” as a combination of special symbols is shown as an example. In addition, among the jackpot symbols, odd numbered numbers (“1, 1, 1” “3, 3, 3” “5, 5, 5” “7, 7, 7” “9, 9, 9” “ 11, 11, 11 "," 13, 13, 13 ") is a specific big symbol, and the other numbers are even numbers (" 2, 2, 2 "," 4, 4, 4 "," 6, 6, 6 ”,“ 8, 8, 8 ”,“ 10, 10, 10 ”,“ 12, 12, 12 ”,“ 14, 14, 14 ”) is a normal big bonus symbol, and the specific big bonus symbol is more than the normal big bonus symbol Benefits more advantageous to the player are given. That is, when the specific bonus symbol is confirmed and displayed, a process of increasing the jackpot probability is executed in the process of step S426 described later.

  Returning to FIG. 23, that is, in the processing of step S353, if the big hit flag F1a is set to 1 (in the case of big hit), the CPU 102 reads out the big hit symbol data stored in the big hit symbol storage buffer, and reads the read The jackpot symbol corresponding to the jackpot symbol data is determined as a symbol to be stopped and displayed on the image display unit 30a of the special symbol display device 6a this time, and stored in a predetermined storage area of the RAM 104.

  On the other hand, if YES in step S347, that is, if the value of the big hit flag F1a is 0, the process proceeds to step S348, and the CPU 102 determines whether or not the value of the reach flag F2a is 0. If the value of reach flag F2a is 0 (YES in step S348), the process proceeds to step S349, and CPU 102 reads out the missed symbol data stored in the missed symbol storage buffer that does not become reach. The outlier corresponding to the read out out symbol data is determined as a symbol to be stopped and displayed on the image display unit 30a of the special symbol display device 6a this time, and stored in a predetermined storage area of the RAM 104.

  On the other hand, if NO in step S348, that is, if the value of the reach flag F2a is 1, the process proceeds to step S350, and the CPU 102 determines whether or not the value of the reach mode flag F3a is 0. If the value of reach state flag F3a is 0 (YES in step S350), the process proceeds to step S351, and CPU 102 loses the data stored in the reach symbol storage buffer other than the plus / minus 1 symbol. The symbol data is read out, and a reach out of symbol other than the plus or minus 1 symbol corresponding to the read out symbol data is determined as a symbol to be stopped and displayed on the image display unit 30a of the special symbol display device 6a this time. Store in the storage area.

  On the other hand, if the value of reach mode flag F3a is not 0 (NO in step S350), that is, if the value of reach mode flag F3a is 1, the process proceeds to step S352, and CPU 102 determines whether plus or minus 1 symbol. Is read out and stored in the image display unit 30a of the special symbol display device 6a at this time. The symbol is determined as a symbol to be stored and stored in a predetermined storage area of the RAM 104.

  When any of steps S349, S351, S352, and S353 is completed, the CPU 102 ends the special symbol determination process (step S346), and proceeds to the special symbol control process of step S354. FIG. 26 is a flowchart showing the special symbol control process (step S354). When this special symbol control process is executed, CPU 102 executes a special symbol variation display process shown in FIG. 27 in step S356.

  FIG. 27 is a flowchart showing the special symbol variation display process (step S356). When the special symbol fluctuation display process is executed, the CPU 102 determines whether or not the value of the big hit flag F1a is 0 in step S358. If the value of the big hit flag F1a is not 0 (NO in step S358), that is, if the value of the big hit flag F1a is 1, the process proceeds to step S359, and the CPU 102 performs the special symbol determination process described above. It is determined whether or not the jackpot symbol corresponding to the jackpot symbol data acquired from the jackpot symbol storage buffer in step S353 of (Step S346) is the above-mentioned odd numbered number symbol symbol, that is, whether or not it is a specific bonus symbol. .

  If YES in step S359, that is, if the jackpot symbol acquired this time is the specific bonus symbol, the process proceeds to step S360, and the CPU 102 changes the variation pattern 4, the variation pattern 22, the variation pattern 32, A process of outputting a variation pattern designation command for instructing the display control circuit 111 to display any variation pattern from among the variation patterns 52 and 62 is executed. On the other hand, if NO in the process of step S359, that is, if the jackpot symbol acquired this time is not a specific bonus symbol (when it is a normal bonus symbol as the above-mentioned even-numbered symbol), step S361 is performed. In the process, the CPU 102 outputs a variation pattern designation command or the like for instructing the display control circuit 111 to display any variation pattern from among the variation pattern 22, the variation pattern 32, the variation pattern 52, and the variation pattern 62. Execute the process.

  On the other hand, if YES in the process of step S358, that is, if the value of the big hit flag F1a is 0, the process proceeds to step S362, and the CPU 102 determines whether or not the value of the reach flag F2a is 0. If the value of the reach flag F2a is 0 (YES in step S362), that is, the symbol data acquired this time is stored so that it does not become reach in step S349 of the special symbol determination process (step S346) described above. If it is out-of-order symbol data acquired from the buffer, the process proceeds to step S363, and the CPU 102 executes processing for outputting a variation pattern designation command or the like for instructing the display control circuit 111 to display variation pattern 1. To do.

  On the other hand, if NO in the process of step S362, that is, if the value of the big hit flag F2a is 1, the process proceeds to step S364, and the CPU 102 determines whether or not the value of the reach state flag F3a is 0. If the value of reach state flag F3a is 0 (YES in step S364), that is, the symbol data acquired this time is other than plus or minus one symbol in step S351 of the special symbol determination process (step S346) described above. If the reach out-of-reach symbol data obtained from the reach symbol storage buffer is selected, the process proceeds to step S365, where the CPU 102 instructs the display control circuit 111 to display the variation pattern 21 or the variation pattern 31. Executes processing to output specified commands.

  On the other hand, if NO in step S364, that is, if the value of the reach state flag F3a is 1, that is, the symbol data acquired this time is plus or minus 1 in step S352 of the special symbol determination process (step S346) described above. If the reach reach symbol data acquired from the symbol reach symbol storage buffer step is reached, the process proceeds to step S366, and the CPU 102 determines whether the variation pattern 21, the variation pattern 31, the variation pattern 51, or the variation pattern 61 is within the range. A process for outputting a variation pattern designation command or the like for instructing the display control circuit 111 to display any variation pattern is executed.

  As will be described later, in the processing of step S360, step S361, step S365, and step S366, one variation pattern is selected from among a plurality of variation patterns. It is determined by the value of the pattern determination counter C8 (random number 8, 0 to 51).

  When the process of step S360, step S361, step S365, or step S366 is completed, the CPU 102 proceeds to the process of step S372 and executes the LED / lamp lighting control process. In this LED / lamp lighting control process (step S372), the CPU 102 drives the above-described lamp control circuit 37 to turn on or blink the LEDs, lamps and the like arranged on the game board surface in a predetermined manner. Execute. By this processing, it is possible to notify the player that the variation pattern related to the big hit or the reach is displayed on the special symbol display device 6a, and it is possible to improve the performance level of the game.

  When the LED / lamp lighting control process in step S372 or the process for instructing the display of the fluctuation pattern 1 in step S363 is completed, the CPU 102 ends the special symbol fluctuation display process (step S356) and proceeds to the process in step S373. Transition.

  Here, referring to FIG. 28, the display control circuit 111 that has received the display instruction of the variation pattern from the main control circuit 44 displays the variation display (slot) of the special symbol displayed on the image display unit 30a of the special symbol display device 6a. Game). FIG. 28 is an explanatory diagram of transmitted data as a change pattern display instruction transmitted from the main control circuit 44 and received by the display control circuit 111 that controls the special symbol display device 6a. The main control circuit 44 uses the variation pattern determined in the special symbol variation display process in step S356 for the special symbol (stop symbol) determined in the special symbol determination processing in step S346 to the left of the special symbol display device 6a. The transmission data shown in FIG. 28 is output for final display after variable display (scroll display) on the symbol display unit 8a, middle symbol display unit 9a, and right symbol display unit 10a.

  This transmission data is output from the main control circuit 44 to the display control circuit 111, and is confirmed from the start of fluctuation of the special symbols displayed by the symbol display units 8a, 9a, 10a of the special symbol display device 6a. Until then, it is specified that five commands are transmitted as display control commands. As shown in (A) and (B) of FIG. 28, these five commands are first transmitted with a variation pattern designation command, then with a left special symbol designation command, and subsequently with a right special symbol designation command, A middle special symbol designation command and all symbol stop designation commands are transmitted.

  As shown in FIG. 28, the left special symbol designating command is transmitted when the time T1 has elapsed since the first variation pattern designating command is transmitted. The right special symbol designation command is transmitted when the time T2 has elapsed since the transmission, and the middle special symbol designation command is transmitted when the time T3 has elapsed since the right special symbol designation command has been transmitted. The all symbol stop designation command is transmitted when the time T has elapsed since the variation pattern designation command was transmitted. Therefore, this time T is the time for the special symbol to change, that is, the time from when the special symbol (the left special symbol, the middle special symbol, the right special symbol) starts to change until it stops on the special symbol display device 6a. The special symbol variation time T is normally set to 7 to 42 seconds (13 to 42 seconds for a big hit or reach, and 7 seconds for others).

  The fluctuation pattern designation command transmitted first includes the value of the fluctuation pattern determination counter C8 (random numbers 8, 0 to 51) acquired in the random number acquisition process in step S212 and the flags (big hit flag F1, reach flag). F2 and reach mode flag F3) are sent based on the current values of fluctuation pattern 1, fluctuation pattern 21, fluctuation pattern 22, fluctuation pattern 31, fluctuation pattern 32, fluctuation pattern 4, fluctuation pattern 51 as described above. 10 types of variation pattern 52, variation pattern 61 and variation pattern 62 are prepared, and the variation state (variation pattern and variation time) of all symbols is indicated. When this is transmitted, the variation of the special symbol is started. The contents of these 10 types of variation patterns will be described later.

  There are 14 types of left special symbol designation commands corresponding to the left special symbols 1 to 14 shown in FIG. 24, and the stop symbol (determined symbol) in the left column is instructed. There are 14 types of right special symbol designation commands corresponding to the right special symbols 1 to 14 shown in FIG. 24, and the stop symbol (determined symbol) in the right column is instructed. The middle special symbol designation commands are prepared in 14 types corresponding to the medium special symbols 1 to 14 shown in FIG. 24, and the middle symbol stop symbol (determined symbol) is instructed. One type of all symbol stop designation commands is prepared, and the stop timing of special symbols in the left column, right column, and middle column is instructed. The above variation pattern designation command, left special symbol designation command, right special symbol designation command, middle special symbol designation command and all symbol stop designation command are transmitted from the main control circuit 44 and received by the display control circuit 111. One change display from when the special symbol starts changing until it is fixedly displayed after being stopped is displayed by each symbol display unit 8a, 9a, 10a of the special symbol display device 6a.

  That is, the special symbol display displayed on the special symbol display device 6a is different in the time from the start of change to the stop of each symbol display unit 8a, 9a, 10a. The parts 8a, 9a, and 10a are performed at the same time, and when the change is stopped, the left symbol display unit 8a is first stopped, then the right symbol display unit 10a is stopped, and finally the middle symbol display unit 9a is stopped. It has become. When the left symbol display unit 8a and then the right symbol display unit 10a are stopped based on the variation pattern related to the big hit or the reach, when the reach that has the same special symbol appears, the image display unit 30a Using the characters stored in the character ROM 145 of the display control circuit 111, various effects (reach actions) that inspire the player are performed.

  Returning to FIG. 26, when the process proceeds to step S <b> 373, the CPU 102 determines whether or not the special symbol variation time T (see FIG. 28) is up (T = 0). If NO in step S373, that is, if it is determined that the special symbol variation time T has not timed up, the CPU 102 ends the special symbol control process (step S354) and performs the process in step S378. Migrate to On the other hand, if YES in the process of step S373, that is, if it is determined that the special symbol variation time T has timed up, the process proceeds to the special symbol confirmation display process of step S374, and the CPU 102 performs the step as described above. A process of confirming and displaying the special symbol determined in the special symbol determination process of S346 on the special symbol display device 6a is executed, and the special symbol control process (step S354) is terminated.

  Returning to FIG. 20, when the process proceeds to step S378, the CPU 102 determines whether or not the special symbol is fixedly displayed on the special symbol display device 6a, and if it is not fixedly displayed (NO in step S378). The special symbol display device 6a game process (step S318) is terminated. On the other hand, if it is determined in the process of step S378 that the special symbol is confirmed and displayed on the special symbol display device 6a (YES in step S378), the process proceeds to step S381, and the CPU 102 receives a big hit here. It is determined whether or not the value of the flag F1a is 1. If NO in step S381, that is, if the value of the big hit flag F1a is 0, the CPU 102 proceeds to the probability change fall process in step S431. On the other hand, when the value of big hit flag F1a is 1 (YES in step S381), the process proceeds to step S385, and CPU 102 executes the big hit process shown in FIG.

  FIG. 29 is a flowchart showing the big hit process (step S385). When the jackpot process (step S385) is executed, the CPU 102 first decreases the jackpot probability increased in the process of step S426 described later in the process of step S386. The process of reducing the jackpot probability is a process for limiting the number of slot games when the jackpot probability is set to a high probability, that is, when the player wins the jackpot probability, the jackpot probability is high. Therefore, if the jackpot probability is not set to a high probability, the process of step S386 is skipped.

  When the process of step S386 is completed, the CPU 102 proceeds to the process of step S387, sets 0 to the probability variation flag F7a, proceeds to the processing of step S389, and sets 0 to the probability variation guarantee flag F5a. Here, the reason why the probability variation guarantee flag F5a is set to 0 is that the special symbol display device 6a may be a big hit during the certainty guarantee, and therefore, in the process of step S389, the probability variation guarantee flag F5a is set to 0. If set, do nothing.

  When the process of step S389 is completed, the CPU 102 proceeds to the process of step S390, and drives the display control circuit 111 to display “normal” and “normal” on the gaming state display devices 32a and 32b, respectively. If “normal” and “normal” are already displayed on the game state display devices 32a and 32b, the process of step S390 is skipped. Then, the process proceeds to step S392, and the CPU 102 determines whether or not it is during the interval time. This interval time is the time during which the big winning opening (attacker) 7a provided during each round in the so-called jackpot game is closed, and when it is determined that the interval time is being reached (YES in step S392) ) Ends the jackpot process (step S385) and proceeds to the process of step S410. On the other hand, if it is determined in step S392 that the interval time is not reached (NO in step S392), the process proceeds to step S394.

  In step S394, the CPU 102 controls the solenoid 106 to open the special winning opening 7a. Then, the process proceeds to step S396, and the CPU 102 determines whether or not the preset opening time 30 seconds for the predetermined prize winning opening 7a has expired, and NO in step S396, that is, When it is determined that the opening time 30 seconds of the special winning opening 7a has not been timed up, the process proceeds to step S398, and it is determined whether or not the value of the counter Da is 10 or more. The counter Da counts the main control circuit 44 in order to count the number of game balls won in the big prize opening 7a until the opened big prize opening 7a is closed after the above-mentioned big prize opening time 30 seconds elapses. Is counted up when the count switch 117a detects a game ball, and is initialized and set to 0 when the power is turned on.

  If NO in step S398, that is, if the value of the counter Da is determined to be less than 10, the CPU 102 ends the jackpot process. On the other hand, when it is determined YES in the process of step S396 or the process of step S398, that is, when it is determined that the opening time 30 seconds of the special winning opening 7a has expired, or the value of the counter Da is determined to be 10 or more. In the case where it is determined, the process proceeds to step S400, and the CPU 102 drives and controls the solenoid 106a to close the special winning opening 7a. Then, the CPU 102 proceeds to the process of step S401, sets the value of the counter Da to 0, proceeds to the process of step S402, and increments (adds 1) the value of the counter Ea. The counter Ea is a counter set in the main control circuit 44 to count how many times the big winning opening 7a is opened, in other words, how many times each round in the big hit game is executed. Every time the process of step S400 is executed and the special winning opening 7a is closed, the count is incremented, and is initialized and set to 0 when the power is turned on.

  When the process of step S402 is completed, the process proceeds to the process of step S404, and the CPU 102 determines whether or not the continuous winning switch 118a is turned on, that is, the gaming ball that has passed through the specific area of the big winning opening 7a. If it is determined whether or not the game ball has passed the specific area of the big winning opening 7a and the continuous winning switch 118a is on (YES in step S404), the CPU 102 performs the process of step S406. Then, it is determined whether or not the value of the counter Ea is less than 16. In the process of step S406, it is determined whether or not the number of times that the big winning opening 7a is opened, that is, whether or not the number of rounds in the big hit game has become 16 times. If YES in step S406, that is, if it is determined that the value of the counter Ea is less than 16, the CPU 102 ends the jackpot process.

  On the other hand, when it is determined NO in the process of step S404 or the process of step S406, that is, when the continuous winning switch 118a is not turned on and the game ball does not pass the specific area of the big winning opening 7a, or the counter Ea When it is determined that the value of 16 is greater than or equal to 16, the CPU 102 proceeds to the process of step S407, sets the value of the counter Ea to 0, proceeds to the process of step S408, and sets the value of the big hit flag F1a. Set to 0 to end the jackpot processing.

  Returning to FIG. 20, when the processing proceeds to step S410, the CPU 102 determines whether or not the value of the big hit flag F1a is 0, that is, whether or not all of the predetermined big hit processing (step S385) is completed, and the big hit flag F1a. If the value is not 0 (NO in the process of step S410), that is, if the value of the big hit flag F1a is 1, it is determined that all of the predetermined big hit processes have not ended, and this special symbol game process (step S318) is terminated. On the other hand, when the value of big hit flag F1a is 0 (YES in step S410), the process proceeds to step S411, and CPU 102 has an odd number of big hit symbols as in the above-described step S359 (FIG. 27). It is determined whether or not it is a number symbol of the second-order, that is, whether or not it is a specific big win symbol.

  If YES in step S411, that is, if the jackpot symbol acquired this time is a specific bonus symbol, the process proceeds to step S426, and the CPU 102 updates the random number update process in step S20 described above. The contents of the big hit determination counter C1 (random numbers 1, 0 to 314) are changed. Normally, the random number 1 created in the process of step S20 has a lottery probability that the special symbol combination is a big win, but it is a big win based on the fact that the specific big symbol is confirmed and displayed. Increase the lottery probability to 5/315. This is done by changing only 7, out of the big hit random numbers composed of 0 to 350 described above as big hit random numbers, to 7, 33, 77, 111, 222.

  When the process of step S426 is completed, the CPU 102 proceeds to the process of step S428, sets 1 to the probability variation flag F7a, proceeds to the process of step S430, sets 1 to the probability variation guarantee flag F5a, and performs the probability variation of step S431. Move on to tumble processing. In addition, as described above, when the answer is NO in step S381 and NO in step S411, that is, when the big hit symbol acquired this time is not the specific big symbol symbol, the CPU 102 proceeds to the probability change fall process in step S431. To do.

  FIG. 30 is a flowchart showing the probability change fall process (step S431). When this probability variation fall process is executed, the CPU 102 first determines whether or not the probability variation flag F7a is set to 1 based on the fact that the jackpot probability has increased in the process of step S428 in the process of step S633. If the determination is NO in step S633, that is, if the probability variation flag F7a is set to 0, the probability variation falling processing is terminated and the routine proceeds to the falling lottery probability changing processing in step S432.

  On the other hand, if YES in the process of step S633, that is, if the probability variation flag F7a is set to 1, the process proceeds to the process of step S635, and the CPU 102 indicates that the jackpot probability has increased in the process of step S430. Based on the above, it is determined whether or not the probability variation guarantee flag F5a is set to 0. If NO in the processing of step S635, that is, the probability variation guarantee flag F5a is set to 1 and the falling lottery is not performed. Finishes this probability change fall process. On the other hand, if YES in the process of step S635, that is, if the probability variation guarantee flag F5a is set to 0 and it is a period for executing the falling lottery, the process proceeds to step S637, and the CPU 102 determines the falling lottery probability. Execute the process.

  FIG. 31 is a flowchart showing the falling lottery probability determination process (step S637). When the falling lottery probability determination process is executed, the CPU 102 first determines whether or not 0 is set in the exchange flag F6 in the process of step S639. If the exchange flag F6 is set to 0 and the answer at step S639 is YES, that is, the probability of the falling lottery is 1/100 on the special symbol display device 6a (1/200 on the special symbol display device 6b). When it is set and “probability change” is displayed on the gaming state display device 32a and “falling probability 1/100” is displayed on the gaming state display device 32b, the process proceeds to step S643, and the CPU 102 will be described later. In the determination performed in the process of step S653 (FIG. 30), the probability variation fall determination counter C9 (falling in the case of random numbers 9, 0-199, 55, 155, probability 1/100) is applied. .

  On the other hand, if the exchange flag F6 is set to 1 and the result of step S639 is NO, that is, the probability of falling lottery is 1/200 on the special symbol display device 6a (1/100 on the special symbol display device 6b). Is set, and the game state display device 32a displays "probability change" and the game state display device 32b displays "falling probability 1/200", the process proceeds to step S649, and the CPU 102 Similarly to the process of step S645, the probability variation fall determination counter C10 is set to be applied to the determination performed in the process of step S653 (FIG. 30) described later. Then, when the process of step S643 or step S649 is completed, the CPU 102 ends the falling lottery probability determination process and proceeds to the process of step S653.

  Returning to FIG. 30, when the process proceeds to step S653, the CPU 102 increases the jackpot probability based on the value of the probability variation fall determination counter C9 or the probability variation fall determination counter C10 acquired in the random number acquisition processing in step S212 described above. The determination of falling from the probability is executed with a predetermined probability. Here, the fall probability used for the determination of the process of step S653 is the probability variation fall determination counter when the random number 9 is set in the process of step S643 in the drop lottery probability determination process (step S637). As for the value of C9, 55 and 155 are won, and 1/100 is applied. On the other hand, when the random number 10 is set in the process of step S649, the value of the probability variation fall determination counter C10 is set. 55 is won and 1/200 is applied.

  If NO in step S653, that is, if it is determined that the jackpot probability is not to be dropped from a high probability at the time when the slot game executed on the special symbol display device 6a is completed, the CPU 102 performs the probability change fall process. Exit. On the other hand, if YES in the process of step S653, that is, if it is determined that the big hit probability falls from the high probability when the slot game executed on the special symbol display device 6a is finished, the CPU 102 proceeds to step S655. The process proceeds to the process, the contents of the jackpot determination counter C1 (random numbers 1, 0 to 314) updated in the random number update process in step S20 described above are changed, and the jackpot probability increased in the process in step S426 described above To lower. This is because when the jackpot probability rises, the random number 1 created in the process of step S20 has a lottery probability that the combination of special symbols is a jackpot, but it is YES in the process of step S653. Reduces the probability of winning a lottery to 1/315. This is done by changing only 7 to the big hit random numbers instead of the big hit random numbers 7, 33, 77, 111, 222 among the big hit random numbers composed of 0 to 350 described above.

  When the process of step S655 ends, the CPU 102 proceeds to the process of step S657, sets 0 to the probability variation flag F7a, proceeds to the process of step S661, and the CPU 102 drives the display control circuit 111. The display of the gaming state display device 32a is switched from “probability change” to “normal”, and the display of the gaming state display device 32b is switched from “falling probability 1/100” or “falling probability 1/200” to “normal”. Through the processing in step S661, the player is notified that the jackpot probability related to the special symbol display device 6a has fallen from a high probability.

  When the process of step S661 is completed, the CPU 102 proceeds to the process of step S663, outputs a probability change fall effect command to the display control circuit 111, and notifies the special symbol display device 6a that the big hit probability has fallen from a high probability. Direct or indirect (suggestive) effect display. This probability change fall effect display will be described in detail later. Therefore, the player recognizes that the jackpot probability related to the special symbol display device 6a has fallen from a high probability in the display of the game state display device 32 and the probability change fall effect display by the processing of step S661 and step S663. Since the prediction can be made and an appropriate judgment can be made for continuing the game thereafter, the gameability of the gaming machine 1 is improved. When the process of step S663 is completed, the CPU 102 ends the probability change fall process.

  When the probability change fall process is finished, the CPU 102 proceeds to the fall lottery probability change process in step S432. FIG. 32 is a flowchart showing the falling lottery probability changing process (step S432). When the falling lottery probability changing process is executed, the CPU 102 first sets 1 in the probability variation flag F7a based on the fact that the big hit probability has increased in the process of step S428 in the process of step S665. It is determined whether the probability change flag F7a is maintained at 1 without winning the falling lottery in the probability variation falling process of S431, and NO is determined in the process of step S665, that is, when the probability variation flag F7a is set to 0. Shifts to the process of step S685.

  On the other hand, if YES in step S665, that is, if 1 is set in the probability variation flag F7a, the process proceeds to step S667, and the CPU 102 determines whether 1 is set in the reach state flag F3a. That is, it is determined whether or not the symbol of the plus / minus 1 symbol is out of reach in the present slot game executed on the special symbol display device 6a. If NO in step S667, that is, if the reach state flag F3a is set to 0, and the reach-unsigned symbol of plus or minus 1 symbol is not confirmed, the process proceeds to step S685.

  On the other hand, if YES in the process of step S667, that is, if the reach state flag F3a is set to 1 and the reach out of 1 plus / minus 1 symbol is confirmed and displayed, the process proceeds to step S669, and the CPU 102 It is determined whether or not 1 is set in the exchange flag F6. If the exchange flag F6 is set to 0 and the result of step S669 is NO, that is, the probability of the falling lottery is reduced to 1/100 on the special symbol display device 6a (1/200 on the special symbol display device 6b). If it is set and “probability change” is displayed on the gaming state display device 32a and “falling probability 1/100” is displayed on the gaming state display device 32b, the process proceeds to step S671, and the CPU 102 1 is set in the exchange flag F6.

  In other words, in the processing from step S667 to step S671, the special symbol display device 6a has determined that the symbol of the plus / minus 1 symbol has been deviated and the special symbol display device 6a starts the special symbol. It is changed to the probability of falling lottery applied to the display device 6b. That is, in the processing from step S667 to step S671, the processing in step S643 is executed until the current slot game in the above-described falling lottery probability determination processing (step S637). The process of step S649 is executed.

  When the process of step S671 is completed, the CPU 102 proceeds to the process of step S675, drives the display control circuit 111 to display “probable change” as it is on the gaming state display device 32a, and the gaming state display device 32b. Is switched from “falling probability 1/100” to “falling probability 1/200”, which means that the probability of the falling lottery of the special symbol display device 6a has been changed, thereby informing the player of that fact. It is supposed to be. When the process of step S675 is completed, the CPU 102 proceeds to the process of step S683. When the processing of step S671 is executed, if the big hit probability is increased and the falling lottery is executed also in the special symbol display device 6b, that is, the game state display devices 33a and 33b indicate “probability change” and “ When “falling probability 1/200” is displayed, in parallel with the processing of step S675, the display of the gaming state display device 33a displays “probability” as it is, and the display of the gaming state display device 33b displays “falling probability”. The display is switched from 1/200 to “falling probability 1/100” which means that the probability of falling lottery of the special symbol display device 6b has been changed.

  On the other hand, when 1 is set in the exchange flag F6 and YES is determined in the process of step S669, that is, the probability of falling lottery is 1/200 on the special symbol display device 6a (1/100 on the special symbol display device 6b). When “probability change” is displayed on the gaming state display device 32a and “falling probability 1/200” is displayed on the gaming state display device 32b, the process proceeds to step S677, and the CPU 102 , 0 is set in the exchange flag F6.

  In other words, in the processing from step S667 to step S677, similarly to the processing from step S667 to step S671 described above, the processing from step S649 is executed up to the current slot game in the above-described falling lottery probability determination processing (step S637). However, the process of step S643 is executed from the next slot game.

  When the process of step S677 is completed, the CPU 102 proceeds to the process of step S681, drives the display control circuit 111 to display “probable change” as it is on the gaming state display device 32a, and the gaming state display device 32b. Is switched from “falling probability 1/200” to “falling probability 1/100”, which means that the probability of falling lottery on the special symbol display device 6a has been changed, so that the player is informed. It is supposed to be. When the process of step S681 is completed, the CPU 102 proceeds to the process of step S683. When the processing of step S677 is executed, if the big hit probability is also increased and the falling lottery is executed in the special symbol display device 6b, that is, the game state display devices 33a and 33b are displayed with “probability change” and “ When “falling probability 1/100” is displayed, in parallel with the process of step S681, the display of the gaming state display device 33a displays “probability change” and the display of the gaming state display device 33b indicates “falling probability”. The display is switched from “1/100” to “falling probability 1/200” which means that the probability of the falling lottery of the special symbol display device 6b has been changed.

  When the process proceeds to step S683, the CPU 102 outputs a fall probability change effect command to the display control circuit 111, and the special symbol display device 6a indicates that the probability of winning the lottery that falls from the high probability has changed. Direct or indirect (suggestive) effect display. The drop probability change effect display will be described in detail later. Also, in the process of step S683, if the jackpot probability is increased and the falling lottery is executed on the special symbol display device 6b, the CPU 102 also displays the fall probability change effect display on the special symbol display device 6b. Let

  Therefore, by the processing of step S675 or step S681 and step S683, the player increases the probability of jackpot on the special symbol display device 6a with a high probability in the display of the game state display device 32 and the fall probability change effect display. When a lottery that falls from the high probability to the big hit probability is being executed, the slot game related to the loss of reach will be displayed when the symbol of the plus / minus 1 symbol is out of reach will be displayed. Therefore, it can be recognized or predicted that the probability of winning the falling lottery will be changed, so that the gaming property of the gaming machine 1 is improved.

  When the process of step S683 is completed, the CPU 102 proceeds to the process of step S685, sets the value of the reach flag F2a to 0, shifts to the process of step S687, and sets the value of the reach mode flag F3a to 0. To do. When it is determined YES in the processes of steps S348 and S362 and when YES is determined in the processes of steps S350 and S364, the CPU 102 performs the processes in steps S685 and S687. , Do nothing. When the process of step S687 is completed, the CPU 102 ends the falling lottery probability changing process and proceeds to the process of step S434.

  Returning to FIG. 20, when the process proceeds to step S434, the CPU 102 decrements (subtracts 1) the value of the counter Ba incremented (added by 1) in the process of step S206 (FIG. 17). The process proceeds to step S436, and the hold LED 25 extinguishing control process is executed. FIG. 33 is a flowchart showing the hold LED 25 extinguishing control process (step S436). When the hold LED 25 extinguishing control process is executed, the CPU 102 first determines whether or not the value of the counter Ba is 1 or more in the process of step S438. If the value of the counter Ba is not 1 or more (in step S438). NO), that is, if the value of the counter Ba is 0, the hold LED 25 extinguishing control process (step S436) is terminated, the special symbol display device 6a game process is terminated, and the special symbol display device 6b game process of step S445 is completed. Migrate to On the other hand, if YES in the process of step S438, that is, if the value of the counter Ba is 1 or more, the process proceeds to step S440, and the CPU 102 selects one of the four hold LEDs 25a, 25b, 25c, and 25d. The corresponding one is driven to turn off the lamp control circuit 37, and the hold LED 25 turn-off control process is finished.

  Returning to FIG. 19, when the special symbol display device 6a game processing (step S318) is completed, the CPU 102 executes the special symbol display device 6b game processing in step S445, but the special symbol display device 6b game processing (step S445) is the same as the special symbol display device 6a game process in step S318 described above, and is as follows. That is, the special symbol display device 6b game processing is the same as the special symbol display device 6a game processing, the special symbol display device 6a, the counter Ba, the big hit flag F1a, the reach flag F2a, the reach mode flag F3a, the probability variation guarantee flag F5a, the probability variation flag F7a, The game status display devices 32a and 32b, the big winning opening 7a, the counter Da, the counter Ea, the continuous winning switch 118a and the holding LED 25 (holding LEDs 25a, 25b, 25c and 25d) are provided with a special symbol display device 6b, a counter Bb, a big hit flag F1b, Reach flag F2b, reach mode flag F3b, probability change guarantee flag F5b, probability change flag F7b, gaming state display device 33a, 33b, big prize opening 7b, counter Db, counter Eb, continuous prize switch 118b and hold LED 29 (hold LEDs 29a, 29b, 29c 29d), and “falling probability 1/100” is changed to “falling probability 1/200” in the processing of step S628 and step S681, and “falling probability 1/200” is changed in the processing of steps S629 and S675. Since the “falling probability 1/100” may be replaced with the random number 9 in the process of step S643 and the random number 10 with the random number 9 in the process of step S649, description thereof is omitted here. When the special symbol display device 6b game process in step S445 is completed, the CPU 102 ends the special symbol game process (step S300), and proceeds to the process in step S50 of the main game process (FIG. 5).

  In addition, in each symbol display part 8a, 8b, 9a, 9b, 10a, 10b of the special symbol display devices 6a, 6b, the mode from the start of change to the stop may be other than those described above, and various modes are considered. For example, when starting fluctuation, a time difference may be provided, or when stopping fluctuation, it may be stopped simultaneously, or the order of starting fluctuation may be changed, or fluctuation may be stopped. The order may be changed. In addition, such various modes may be mixed so that the player is notified that the result of the variation display will be a big hit or reach. If it does in this way, according to the aspect from a change start to a stop, a player can assume what kind of result this change display will become, gameability will improve, and a player's willingness to play will increase.

  In addition, the special symbol stop means a state in which, for example, several frames are slightly moved up and down on each of the symbol display portions 8a, 8b, 9a, 9b, 10a, and 10b (below, in a state of being completely stopped) Such a state is also referred to as “shake”). That is, the special symbol may be stopped in any manner as long as the player can recognize the special symbol even if the special symbol is not completely stopped.

  In addition, in the falling lottery probability changing process (FIG. 32) in step S432, for example, when the symbol of the plus or minus 1 symbol is deviated and displayed on the special symbol display device 6a, the special symbol display device 6b side selects the falling lottery. It is also conceivable that the related slot game is being executed. In other words, both the special symbol display devices 6a and 6b have increased jackpot probabilities. For example, the game state display devices 32a and 32b have “probability change”, “falling probability 1/100”, and the game state display devices 33a and 33b have “probability change”. When the “falling probability 1/200” is displayed, the special symbol display device 6b displays the slot game in the special symbol display device 6b when the symbol of the plus / minus one symbol is displayed in the slot game on the special symbol display device 6a. In such a case, the following may be performed.

  That is, the fall probability related to the special symbol display device 6a is changed from 1/100 to 1/200 immediately when the symbol of the plus / minus 1 symbol is deviated and displayed on the special symbol display device 6a. The display of the device 32b is changed from "falling probability 1/100" to "falling probability 1/200", but the falling probability related to the special symbol display device 6b is a special symbol display device 6a with a plus / minus 1 symbol out of reach. At the time of the confirmation display, the slot game currently displayed on the special symbol display device 6b is changed after the slot game is ended, and the display on the game state display device 33b is linked to the “ You may make it change from "falling probability 1/200" to "falling probability 1/100". In this way, the fall probability associated with the special symbol display device 6b is not changed during the slot game displayed on the special symbol display device 6b. Since the game is not changed in the middle of the slot game, the player recognizes that the falling probability related to the special symbol display device 6b is changed from the next slot game, and as a result, the progress of the game for the player Becomes much easier to understand and the game is improved. In this case, the fall probability change effect display displayed on the special symbol display device 6b may be displayed after the slot game is ended.

  It should be noted that a display control command output to the display control circuit 111 in the special symbol game process (step S300), for example, a probable change guarantee effect command in step S625, a falling lottery start effect command in step S631, step S360, step S361, step S363, Steps S365 and S366, variation pattern designation command, left special symbol designation command, right special symbol designation command, middle special symbol designation command and all symbols stop designation command shown in FIG. 28, step S663 probable fall effect command, step S683 The main control circuit 44 uses a predetermined number of bits (for example, the display control command) so that each of the display control commands such as the fall probability change effect command can be identified as to which of the special symbol display devices 6a or 6b is a display instruction. 1 The display control circuit 111 sends the display control command received from the main control circuit 44 based on this identifier to the special symbol display device 6a or It is determined which of 6b is a display instruction.

  As is apparent from the above description, in this special symbol game process (step S300), the special symbol display device 6a is special for the winning at the starting winning port 11b with respect to the winning at the starting winning port 11a. When the slot game is executed individually and independently on the symbol display device 6b, and the special symbol display device 6a or 6b is confirmed and displayed, the special symbol display device 6a or 6b is displayed after the big hit game is over. When the jackpot lottery is changed with a high probability, and the special symbol display device 6a or 6b wins the falling lottery, the special symbol display device 6a or 6b that wins the falling lottery is concerned. Only the big hit probability is changed to a low probability. In other words, the probability variation (increase or decrease) of the big hit probability and the start and end of the falling lottery are individually executed by the special symbol display devices 6a and 6b, and depending on the timing, these big hit games and The falling lottery can be generated at the same time. Therefore, in such a gaming machine 1, a player can enjoy two games at the same time in parallel with one gaming machine 1, that is, it is possible to acquire a big hit game at the same time. As a result, the game preferences are greatly improved.

  Returning to FIG. 5, when the special game process (step S40) is completed, the CPU 102 proceeds to step S50 and executes other processes. In the other processing of step S50, the CPU 102 determines signals relating to various gaming states from the above-mentioned external information terminal 109 based on the above-described various flags (see FIG. 22), for example, during big hit processing, falling state, falling A signal indicating that the lottery is being executed, the probability change is being guaranteed, the fall probability is being changed, or the jackpot probability is being increased is output to a hall management computer (not shown) outside the gaming machine 1.

  Since the gaming machine 1 also outputs a signal indicating the number of shot balls (out balls) and the number of winning balls (safe balls) to the hall management computer or the like, the hall control computer or the like can therefore output the hall. When the manager is performing various lottery data of the gaming machine 1, for example, what kind of gaming state was when the big hit occurred, that is, when the big hit is a big hit in the fall state, the big hit probability is increasing, and the falling lottery is being executed The player's payout ball per unit time that was a big hit when the fall probability was changed while the big hit probability or the big hit probability was changed, or considering various gaming conditions (for example, when the big hit probability was not rising) The number of (base sphere) can be known. That is, since the game data of the gaming machine 1 can be analyzed in detail, adjustment of the gaming machine 1 after closing, for example, nail adjustment can be performed accurately.

  Such game data may be displayed on the special symbol display devices 6a and 6b included in the gaming machine 1 itself, in addition to the hall management computer outside the gaming machine 1 and the like. In this way, the hall clerk can refer to this game data during business, so only a player who has won a jackpot during the fall state can receive various services based on this game data. It will be possible to provide special services, etc., which will be beneficial for sales.

  In addition, in the other processing of step S50, various processing is executed in addition to these processing. However, since the processing is not particularly related to the present invention, description thereof is omitted here. When the process of step S50 is completed, the CPU 102 proceeds to step S60 and executes a random number update process. This performs a loop process that continuously updates the values of the random number counters C1 to C12 (see FIG. 6) in the random number update process of step S20 described above until the next reset interrupt occurs.

  Specifically, the CPU 102 executes each process of step S20 to step S60 every reset interrupt (2 msec), but the time required to execute these processes is not the same every time. Accordingly, it is necessary to set the time of 2 msec for generating the reset interrupt with a margin, and the remaining time still occurs when the CPU 102 finishes the process of step S50. In step S60, the remaining time is used to update the values of the random number counters C1 to C12. For example, the values of the random number counters C1 to C12 are incremented (add 1) until the remaining time is consumed. Or the process which continues decrementing (1 subtraction) is performed, or the process which continues updating the value of each random number counter C1-C12 by a predetermined numerical formula etc. is performed.

  In addition, without updating the values of the random number counters C1 to C12, specific random number counters such as a big hit determination counter C1, a big hit symbol determination counter C7, a positive variation fall determination counter C9, C10, and a hit determination counter C11 are called. As described above, only the random number counter that greatly affects the player's profit may be updated, and the values of the random number counters C1 to C12 may not be updated every reset interrupt (2 msec). For example, it may be performed every time the random number value of each random number counter is one cycle. In this way, program design is facilitated and processing operations of the CPU 102 and the like can be reduced. Thus, by updating the predetermined random number counter using the remaining time of the reset interrupt that is repeatedly executed every 2 msec of the main game process, the increment of the value of the predetermined random number counter in one process is irregular. Thus, it is possible to make it difficult for an unfair strategy using a player's sensory device or the like, for example, a player's strategy to hit a big hit random number or the like.

  Next, with reference to FIG. 34, 10 types of variation patterns related to the special symbol described above will be described. FIG. 34 is a distribution diagram of the fluctuation pattern in the main control circuit 44. As shown in FIG. 34, the ten types of variation patterns are variation pattern 1, variation pattern 21, variation pattern 22, variation pattern 31, variation pattern 32, variation pattern 4, variation pattern 51, variation pattern 52, variation pattern 61 and First, the variation pattern 1 is a variation pattern that is selected when a non-reachable symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time. Regardless of the counter C8 (random numbers 8, 0 to 51), the variation pattern designation command corresponding to the variation pattern 1 is transmitted from the main control circuit 44 to the display control circuit 111, so that the special symbol display devices 6a and 6b Fluctuation is displayed.

  The variation pattern 21 is a variation pattern that is selected when a reach-excluded symbol of plus / minus 1 symbol or a symbol other than a plus / minus 1 symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b. The variation corresponding to the variation pattern 21 when the obtained numerical value of the variation pattern determination counter C8 (random number 8, 0 to 51) is 0 to 24 (probability 25/52) or 0 to 29 (probability 30/52). When the pattern designation command is transmitted from the main control circuit 44 to the display control circuit 111, the pattern designation command is variably displayed on the special symbol display devices 6a and 6b.

  The fluctuation pattern 22 is a fluctuation pattern that is selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time, and an odd number of big hit symbols (specific big bonus symbols are stored in the big hit symbol storage buffer) ) Is stored (Obtained symbol determination counter C7 (random number 7, 0 to 13) is 0, 2, 4, 6, 8, 10, 12, probability 1/2), acquisition of variation pattern determination counter C8 A numerical value of 1 to 5 (probability 5/52) or an even number of big hit symbols (usually big hit symbols) is stored in the big hit symbol storage buffer (the big hit symbol determination counter C7 gets a numerical value of 1, 3, 5, 7, 9, 11, 13, probability ½) and the obtained value of the variation pattern determination counter C <b> 8 is 0 to 5 (probability 6/52), the variation pattern designation command corresponding to the variation pattern 22 is the main control circuit 44. By being sent to the al display control circuit 111, it is variably displayed special symbol display device 6a, to 6b.

  The variation pattern 31, like the variation pattern 21, is selected when the reach-removed symbol of the plus / minus 1 symbol or the reach-reversed symbol other than the plus / minus 1 symbol is determined as the symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time. Change pattern corresponding to the change pattern 31 when the obtained numerical value of the change pattern determination counter C8 is 25 to 31 (probability 7/52) or 30 to 51 (probability 30/52). When the command is transmitted from the main control circuit 44 to the display control circuit 111, the special symbol display devices 6a and 6b are variably displayed.

  Like the variation pattern 22, the variation pattern 32 is a variation pattern that is selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time, and an odd number of big hits is stored in the big hit symbol storage buffer. The symbol (specific big bonus symbol) is stored (the acquired value of the big hit symbol determining counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and the acquired numerical value of the variation pattern determining counter C8 is 6 to 10 (probability 5/52) or even a big hit symbol storage buffer (usually big hit symbol) is stored in the big hit symbol storage buffer (obtained value of the big hit symbol determination counter C7 is 1, 3, 5, 7, 9, 11, 13, probability 1/2), and the fluctuation pattern designation command corresponding to the fluctuation pattern 32 is the main control when the obtained numerical value of the fluctuation pattern determination counter C8 is 6 to 10 (probability 5/52). By being transmitted from the road 44 to the display control circuit 111, it is variably displayed special symbol display device 6a, to 6b.

  The variation pattern 4 is a variation pattern that is selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time. ) Is stored (obtained numerical value of the jackpot symbol determination counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and the acquired numerical value of the variation pattern determination counter C8 is 0 (probability 1/52). ), A variation pattern designation command corresponding to the variation pattern 4 is transmitted from the main control circuit 44 to the display control circuit 111, so that it is variably displayed on the special symbol display devices 6a and 6b.

  The variation pattern 51 is a variation pattern that is selected when the reach / decrease symbol of one plus or minus one symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time, and the variation pattern determination counter C8 is acquired. When the numerical value is 32 to 41 (probability 10/52), a variation pattern designation command corresponding to the variation pattern 51 is transmitted from the main control circuit 44 to the display control circuit 111, so that the special symbol display devices 6a and 6b Fluctuation is displayed.

  Like the variation pattern 22, the variation pattern 52 is a variation pattern that is selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time, and an odd number of big hits is stored in the big hit symbol storage buffer. The symbol (specific big bonus symbol) is stored (the acquired value of the big hit symbol determining counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and the acquired numerical value of the variation pattern determining counter C8 is 11 to 35 (probability 25/52) or even a big hit symbol (usually big win symbol) is stored in the big hit symbol storage buffer (the acquired value of the big hit symbol determination counter C7 is 1, 3, 5, 7, 9, 11, 13, probability 1/2), and fluctuation pattern designation command corresponding to the fluctuation pattern 52 when the obtained numerical value of the fluctuation pattern determination counter C8 is 11 to 26 (probability 16/52) By being transmitted from the main control circuit 44 to the display control circuit 111, it is variably displayed special symbol display device 6a, to 6b.

  Similar to the variation pattern 51, the variation pattern 61 is a variation pattern that is selected when the symbol of the plus / minus one symbol is determined to be stopped and displayed on the special symbol display devices 6a and 6b this time. When the obtained numerical value of the determination counter C8 is 42 to 51 (probability 10/52), a variation pattern designation command corresponding to the variation pattern 61 is transmitted from the main control circuit 44 to the display control circuit 111. The display is variably displayed on the display devices 6a and 6b.

  Like the variation pattern 22, the variation pattern 62 is a variation pattern that is selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display devices 6a and 6b this time, and an odd number of big hits is stored in the big hit symbol storage buffer. The symbol (specific big bonus symbol) is stored (the acquired value of the big hit symbol determining counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and the acquired numerical value of the variation pattern determining counter C8 is 36 to 51 (probability 16/52) or even a big hit symbol storage buffer (usually big hit symbol) is stored in the big hit symbol storage buffer (the acquired numerical value of the big hit symbol determination counter C7 is 1, 3, 5, 7, 9, 11, 13, probability 1/2), and a variation pattern designation command corresponding to the variation pattern 62 when the obtained numerical value of the variation pattern determination counter C8 is 27 to 51 (probability 25/52) By being transmitted from the main control circuit 44 to the display control circuit 111, it is variably displayed special symbol display device 6a, to 6b.

  Here, the variation pattern 21 is a variation pattern 22, the variation pattern 31 is a variation pattern 32, the variation pattern 51 is a variation pattern 52, and the variation pattern 61 is a variation pattern of an effect display almost the same as the variation pattern 62, In the last part of the reach action, only the effect display of whether the reach is lost or the big hit is different. By doing so, the player cannot predict whether or not the big hit will occur unless he / she sees the reach action of these fluctuation patterns to the end, and as a result, the gameability of the gaming machine 1 is improved. On the other hand, the variation pattern 4 is a variation pattern (so-called premium reach) that is displayed only at the time of a big hit, and is displayed only when a specific large symbol is displayed. When the variation pattern 4 is displayed, it is convinced that it will be a big hit with a specific bonus symbol.

  Next, processing executed by the display control circuit 111 will be described in detail. FIG. 35 shows strobe signal interrupt processing executed when the strobe signal output from the main control circuit 44 is input to the INT terminal of the CPU 140 of the display control circuit 111. When the strobe signal is input to the INT terminal, the CPU 140 receives the display control command signal as described above in the process of step S701, proceeds to the process of step S703, and receives the display control command received here. The signal is stored in a predetermined storage area of the RAM 141.

  Next, based on the fact that the display control circuit 111 receives various display control commands from the main control circuit 44, various variation patterns, effects, etc. are displayed on the image display units 30a, 30b of the special symbol display devices 6a, 6b. A display process executed by the display control circuit 111 in connection with the display will be described. FIG. 36 is a flowchart showing a display main control process (main routine) executed by the CPU 140 of the display control circuit 111.

  Immediately after the power is turned on, the CPU 140 initializes each flag, each register, each storage area, and the like necessary for stack setting and the following processing as initialization processing (step S710). When completing the initialization process in step S710, the CPU 140 proceeds to the random number update process in step S711. The CPU 140 receives a main routine (each program stored in the ROM 142 of the display control circuit 111) every time an interrupt signal is received from the VDP 143 in step S732 described later, that is, in steps S711 to S732 described below. Execute each process.

  FIG. 37 is a list of main random numbers handled in the display control circuit 111. In the main control circuit 44, as shown in FIG. 37, various counters C21 to C24 (random numbers 21 to 24) are set as random numbers for setting the display mode of each effect display at random. CPU140 updates the value regarding each counter C21-C24 by the random number update process of step S711.

  The probability variation guarantee effect display determination counter C21 (random numbers 21, 0 to 99) is maintained in the image display units 30a and 30b of the special symbol display devices 6a and 6b without a falling lottery and a high probability of winning. This is a random number counter for determining a probability variation guaranteed effect display for direct or indirect (implicit) effect display that is guaranteed to be guaranteed, starting from 0 when the power is turned on, and in step S732 described later Every time an interrupt signal is received from the VDP 143, it is incremented (added by 1). However, when this random number counter C21 becomes 100, it is rewritten to 0. Although not shown in the drawing, five types of guaranteed variation guarantee display are prepared, and one of the five guaranteed variation representations is selected based on the value of the counter C21 for determining the guaranteed variation display. It has come to be.

  The falling lottery start effect display determination counter C22 (random numbers 22, 0 to 99) indicates that the lottery for dropping the big hit probability from the high probability is started on the image display units 30a and 30b of the special symbol display devices 6a and 6b. This is a random number counter for determining a falling lottery start effect display for effect display directly or indirectly (implicitly), starting from 0 when the power is turned on, and receiving an interrupt signal from the VDP 143 in step S732 described later. It is incremented (added by 1) every time. However, when this random number counter C22 becomes 100, it is rewritten to 0. Although not shown, five types of falling lottery start effect display are prepared, and one of the five types of falling lottery start effect display is set to the value of the counter for falling lottery start effect display determination C22. Based on the selection.

  The probability change fall effect display determination counter C23 (random numbers 23, 0 to 99) directly or indirectly indicates that the big hit probability has fallen from a high probability to the image display units 30a and 30b of the special symbol display devices 6a and 6b ( This is a random number counter for deciding the probability change fall effect display to be displayed implicitly, starting from 0 when the power is turned on, and incrementing (adding 1) every time an interrupt signal is received from the VDP 143 in step S732 described later. Is done. However, when the random number counter C23 becomes 100, it is rewritten to 0. Although not shown in the drawing, five types of probability variation fall effect display are prepared, and one of the five probability variation fall effect displays is selected based on the value of the probability variation fall effect display determination counter C23. It has come to be.

  The fall probability change effect display determination counter C24 (random numbers 24, 0 to 99) is displayed on the image display units 30a and 30b of the special symbol display devices 6a and 6b and the probability of the fall lottery concerning the special symbol display device 6a and the special symbol. Fall probability change to display directly or indirectly (suggested) that the probability of winning a lottery that falls from a high probability is changed and the probability of falling lottery related to the display device 6b is changed. A random number counter for determining the effect display, which starts from 0 when the power is turned on, and is incremented (added by 1) every time an interrupt signal is received from the VDP 143 in step S732 described later. However, when this random number counter C24 becomes 100, it is rewritten to 0. Although not shown, five types of fall probability change effect display are prepared, and any one of the five types of fall probability change effect display is set to the value of the fall probability change effect display determination counter C24. Based on the selection.

  Returning to FIG. 36, in step S711, the CPU 140 determines the probability variation guarantee effect display determination counter C21, the falling lottery start effect display determination counter C22, the probability variation fall effect display determination counter C23, and the fall probability change effect display determination. When the random number updating process of the counter C24 is completed, the process proceeds to the process of step S712, where the display control command signal is received in the strobe signal interrupt process described above, that is, the received display control command signal is stored in the RAM 141. It is determined whether it is stored in a predetermined storage area. If the display control command signal has not been received (NO in step S712), the process proceeds to step S724.

  On the other hand, when the display control command signal is received (YES in step S712), CPU 140 proceeds to the process in step S713, and acquires the current values of the counters C21 to C24 described above. The stored value is stored in the acquired numerical value storage area of the RAM 141, and the process proceeds to step S714 to decode the received display control command. In the process of step S714, the CPU 140 stores the display control command data stored in the predetermined storage area of the RAM 141 in the process of step S703 of the strobe signal interrupt process described above in the RAM 141 that is reserved for decoding. The display control command is decoded by copying the data to the storage area and reading the copied data from the storage area for decoding. This has the effect of preventing the received display control command data from being erased due to overwriting or the like. When the process of step S714 is completed, the CPU 140 proceeds to the process of step S724. In the process of step S714, the CPU 140 also decodes an identifier for identifying which of the special symbol display devices 6a or 6b is given to the display control command signal.

  When the process proceeds to step S724, the CPU 140 decodes the decoded display control command, the values of the counters C21 to C24 acquired in the process of step S713 (the decoded display control command is the guaranteed change guarantee effect command, the falling lottery start effect Control data for performing display control for displaying the next one-frame image on the image display units 30a and 30b from the ROM 142 according to the command, the probability change fall effect command, or the fall probability change effect command) and the identifier, and the RAM 141 Is used as a work area to calculate the image data as described above, the process proceeds to step S726, and the image display unit 30a, 30b performs an image effect corresponding to the display control command decoded here. A drawing command as described above is created and stored in the RAM 141.

  Then, the process proceeds to step S728, and the CPU 140 outputs the calculation result of the image data and the created drawing command as a control signal to the VDP 143, and the process proceeds to step S732. In the process of step S728, the CPU 140 sends the VDP 143 with the same identifier as the display control command data described above so that the control signal for the special symbol display device 6a or 6b can be identified. It has become.

  Further, the processing time from step S711 to step S728 is inputted with one frame image for display next time, that is, a vertical synchronizing signal, and the LCD driving circuit 150a drives the image display unit 30a of the special symbol display device 6a or the LCD driving. The processing time of the CPU 140 for creating an image of one frame to be displayed next time on the image display unit 30b of the special symbol display device 6b by the circuit 150b. In other words, the processing of CPU 140 from step S711 to step S728 executed this time is based on the processing of CPU 140 from step S712 to step S728 executed last time by the LCD drive circuit 150a or the image display unit 30a. Are processed during one frame of image display processing on the image display unit 30b (1/30 seconds, a time obtained by adding a vertical blanking period and a vertical display period described later).

  In step S732, the CPU 140 waits until an interrupt signal is received from the VDP 143 (NO in step S732). The interrupt signal from the VDP 143 is synchronously input to an INT terminal (not shown) of the CPU 140 (every 1/30 seconds) every time a vertical synchronization signal is input from the timing controller 149 to the VDP 143. Then, using the waiting time until the interrupt signal from the VDP 143 is received in the process of step S732, the CPU 140 performs the random number counters C21 to C21 in the random number update process of step S711 described above in the process of step S730. A loop process for continuously updating the value of C24 (see FIG. 37) is performed. The specific process of step S730 is the same as the random number update process of step S60 of the main game process (FIG. 5) described above, and a description thereof will be omitted here. When the interrupt signal from the VDP 143 is received in the process of step S732 (YES in the process of step S732), the CPU 140 proceeds to the process of step S712 and thereafter receives the interrupt signal from the VDP 143 ( This display main control process is repeated every 1/30 seconds.

  Next, display control processing executed by the VDP 143 will be described with reference to FIG. FIG. 38 is a flowchart showing a VDP display control process executed by the VDP 143. Immediately after the power is turned on, the VDP 143 performs initialization processing of the VRAM 144 and the like in the process of step S802, and proceeds to the process of step S804. It is determined whether or not a control signal output is received. If the control signal is not received from CPU 140 (NO in step S804), the control waits until the control signal is received, and if it is determined that the control signal is received from CPU 140 (step S804). In step S804, YES, the VDP 143 proceeds to step S806.

  When the process proceeds to step S806, the VDP 143 reads out the appropriate image data from the character ROM 145 based on the received control signal, and the image display unit 30a based on the image data read out from the character ROM 145 and the received control signal. , 30b, image data for displaying the next one frame image is generated. Then, the process proceeds to step S810, and the VDP 143 determines whether or not the generated image data for display is for the special symbol display device 6a.

  If YES in the process of step S810, that is, if the generated display image data is for the special symbol display device 6a, the process proceeds to step S812, and the VDP 143 is partitioned on the VRAM 144. The generated image data for display is stored in the storage area for the special symbol display device 6a. On the other hand, if NO in step S810, that is, if the generated display image data is for the special symbol display device 6b, the process proceeds to step S814, and the VDP 143 is partitioned on the VRAM 144. The generated image data for display is stored in the storage area for the special symbol display device 6b. In the process of step S810, the VDP 143 determines whether the generated image data for display is for the special symbol display device 6a or the special symbol display device 6b based on the identifier from the CPU 140.

  When the process of step S812 or step S814 is completed, the process proceeds to step S816, and the VDP 143 waits until a vertical synchronization signal (every 1/30 seconds) is received from the timing controller 149 (the process of step S816). NO). On the other hand, when the vertical synchronization signal from the timing controller 149 is received in the process of step S816 (YES in the process of step S816), the VDP 143 proceeds to the process of step S818. Note that the standby time in the process of step S816 is the free time of the VDP 143.

  When the process proceeds to step S818, the VDP 143 outputs an interrupt signal to the INT terminal (not shown) of the CPU 140, and the process proceeds to step S822 where the VRAM 144 is transferred to the LCD drive circuit 150a or the LCD drive circuit 150b. The image data stored in is output. FIG. 39 is a flowchart showing LCD drive circuit output processing executed by the VDP 143. When this process is started, the VDP 143 determines whether the image data developed in the VRAM 144 in the process of step S824 is image data for the special symbol display device 6a, that is, in the process of step S812 of the VDP display control process. It is determined whether the image data is stored in the storage area for the special symbol display device 6a of the VRAM 144.

  If YES in step S824, that is, if the image data is stored in the storage area for the special symbol display device 6a in the VRAM 144, the process proceeds to step S826 and the special symbol display device 6a is used. The image data stored in the storage area is output to the LCD drive circuit 150a. On the other hand, if NO in the process of step S824, that is, if the image data is stored in the storage area for the special symbol display device 6b in the VRAM 144, the process proceeds to the process of step S828, and for this special symbol display device 6b. The image data stored in the storage area is output to the LCD drive circuit 150b. That is, the VDP 143 outputs one frame of image data stored in the VRAM 144 to the LCD drive circuit 150a or the LCD drive circuit 150b every time a vertical synchronization signal is received from the timing controller 149 (every 1/30 seconds).

  Therefore, for example, when both of the special symbol display devices 6a and 6b are executing a slot game, the VDP 143 displays one frame image on both the LCD drive circuit 150a and the LCD drive circuit 150b during one frame. On the other hand, if only one of the special symbol display devices 6a and 6b is executing the slot game, the VDP 143 will execute the slot game during one frame. One frame of image data is output to the display device 6a or the special symbol display device 6b.

  Then, based on the image data output in step S826, the LCD drive circuit 150a displays a predetermined image (for example, a big hit effect image) on the image display unit 30a of the special symbol display device 6a in accordance with the NTSC system. Then, based on the image data output in step S828, the LCD drive circuit 150b similarly applies a predetermined image (for example, a slot game) to the image display unit 30b of the special symbol display device 6b in accordance with the NTSC system. Image).

  When the process of step S826 and the process of step S828 are completed, the VDP 143 ends the LCD drive circuit output process (step S822), returns to the VDP display control process, and proceeds to the process of step S804. This VDP display control process is repeated every time a vertical synchronization signal is received from the controller 149 (every 1/30 seconds).

  In the process from step S804 to step S812 or step S814, an image of one frame to be displayed next time, that is, a vertical synchronization signal is input, and images of the special symbol display devices 6a and 6b are input by the LCD drive circuits 150a and 150b. The VDP 143 process for displaying the next one frame image on the display units 30a and 30b is performed. While the one-frame image display processing is executed on the image display units 30a and 30b of the display devices 6a and 6b (the time obtained by adding a vertical blanking period and a vertical display period to be described later for 1/30 seconds), the VDP 143 Processing time to execute.

  That is, in this VDP display control processing, the processing from step S804 to step S822 (processing time + free time) executed by the VDP 143 is performed by the LCD driving circuit 150a on the image display unit 30a of the special symbol display device 6a or by LCD driving. It is equal to one frame image display processing time (1/30 second) displayed on the image display unit 30b of the special symbol display device 6b by the circuit 150b.

  Here, the image processing of the CPU 140 and the VDP 143 related to the display control processing executed by the display control circuit 111 will be described in more detail with reference to FIG. FIG. 40 is an explanatory diagram for describing image processing executed by the CPU 140 and the VDP 143 in one frame.

  In FIG. 40, 1/30 second (time of one frame) is a period in which a vertical synchronization signal is input from the timing controller 149 to the LCD driving circuits 150a and 150b, and the LCD driving circuits 150a and 150b are connected to the image display unit. This is a processing time for displaying an image of one frame on 30a and 30b, and this one frame time (1/30 second) is composed of a vertical blanking period and a vertical display period. The vertical blanking period is a period (vertical blanking period) in which the vertical blanking generated when a vertical synchronizing signal is input to the LCD drive circuits 150a and 150b (vertical blanking period). In this period, the image display unit The image of one frame displayed on 30a and 30b is not rewritten. The vertical display period is a period from the end of the vertical blanking period to the input of the next vertical synchronization signal, and the horizontal synchronization signal from the timing controller 149 and the VDP display control process (FIG. 38). Based on one frame of image data input in the process of step S822 (one frame of image data stored in the VRAM 144 in the process of step S812 or step S814), the LCD drive circuits 150a and 150b convert the image of one frame. This is a period during which images are rewritten and displayed on the image display units 30a and 30b.

  The VDP 143 outputs an interrupt signal to the INT terminal (not shown) of the CPU 140 in synchronism with the input of the vertical synchronization signal from the timing controller 149, and the VRAM 144 at the time of the previous one frame (1/30 seconds). Is output to the LCD driving circuits 150a and 150b. Then, by receiving the calculation result of one frame of image data related to the display control command signal and the control signal as the drawing command from the CPU 140, the suitable image data is read from the character ROM 145, and the image display units 30a and 30b are read next time. The image data for displaying one frame image is generated, and the generated image data for display is stored in the VRAM 144.

  These processes of VDP 143 correspond to the processes of step S818, step S822, step S804, step S806, step S810, step S812, and step S814 of the VDP display control process (FIG. 38). When a vertical synchronization signal is input from the timing controller 149, one frame of image data is processed in such a processing order (step S818 to step S814) in the time of one frame (1/30 second). The time required for these processes is the processing time indicated by the white arrow in FIG. Therefore, the time obtained by subtracting this processing time from the time of 1 frame (1/30 second) is the free time in 1 frame of VDP 143. This processing time (free time) is different for each frame, and this is due to the amount of image data processed by the VDP 143 being different for each frame. For example, when the VDP 143 performs advanced image processing such as a complicated moving image or a three-dimensional image, the processing time becomes longer, and the idle time becomes shorter than that.

  Next, when the interrupt signal from the VDP 143 synchronized with the vertical synchronization signal is input, the CPU 140 updates the counters C21 to C24 (see FIG. 37) and displays the display control command received from the main control circuit 44. Based on the decoded display control command, the control data for performing display control for displaying the next one frame image on the image display units 30a and 30b is read out from the ROM 142 to calculate and draw the image data. A command is created, and the calculation result of the image data of one frame and the created drawing command are stored in the RAM 141. Then, the calculation result of one frame of image data stored in the RAM 141 and the created drawing command are output to the VDP 143 as control signals.

  These processes of the CPU 140 correspond to steps S711 to S728 of the display main control process (FIG. 36). That is, when the CPU 140 inputs an interrupt signal from the VDP 143, the time of one frame (1 / 30 seconds), one frame of image data is processed in such a processing order (steps S711 to S728). The time required for these processes is the processing time indicated by the white arrow in FIG. It becomes. Accordingly, the time obtained by subtracting this processing time from the time of 1 frame (1/30 second) is the random number update processing time of each counter C21 to C24 in one frame of the CPU 140 corresponding to the processing of step S730 of the display main control processing. It becomes. Note that this processing time (random number update processing time) is different for each frame, and this is because the amount of image data processed by the CPU 140 is different for each frame, like the VDP 143. In FIG. 40, the processing time of the CPU 140 and the VDP 143 within one frame time (1/30 second) is indicated by a single white arrow for convenience, but the processing time of the CPU 140 and the VDP 143 is actually Are not the same, but have different times.

  Here, when the display control circuit 111 receives a probability change guarantee effect command, a fall lottery start effect command, a probability change fall effect command, and a fall probability change effect command as a display control command, it is displayed on the special symbol display device 6a or 6b. The effect image will be described. When the display control command decoded in step S714 of the display main control process (FIG. 36) is a probability change guarantee effect command, the CPU 140 acquires the counters C21 to C24 acquired in step S713. Is selected from among the five types of probability variation guarantee effect display based on the value of the probability variation guarantee effect display determination counter C21, and the character, background, etc. corresponding to the selected probability variation guarantee effect display. The image is displayed on the image display unit 30a or 30b by the VDP 143 based on the identifier.

  That is, after the display control circuit 111 receives the probability variation guarantee effect command for the special symbol display device 6a or 6b from the main control circuit 44, the CPU 140 next receives the interrupt signal from the VDP 143 and the probability variation guarantee effect display determination counter. The value of C21 (random number 21, 0 to 99) is acquired, and one of the above-described five types of probability variation guarantee effect displays is determined and displayed on the image display unit 30a or 30b. Accordingly, the uniformity and irregularity of the numerical values acquired by the probability variation guarantee effect display determination counter C21 are ensured. Therefore, when the probability variation guarantee effect display is displayed on the image display unit 30a or 30b, the contents of the probability variation guarantee effect display are displayed. Thus, the uniformity and irregularity of the gaming machine 1 are guaranteed, and the gaming property of the gaming machine 1 is improved.

  Note that the content of the certainty guarantee effect display is not particularly limited, but it is guaranteed that the special winning symbol display device 6a or 6b is not subjected to the falling lottery and the jackpot probability is maintained at a high probability. It may be an image including characters displayed directly or indirectly (suggestively), for example, characters such as “maintaining high probability!” “No falling lottery!” “Guaranteed to change probability”, “chance!” In addition, the probability variation guarantee display is displayed on the image display section 30a or 30b on which the slot game is displayed, just before the slot game with the holding ball immediately after the big hit game is started. . Further, the probability variation guarantee display may be continuously displayed during the probability variation guarantee period (a slot game (usually four times) executed based on the reserved ball before the big hit game), or the probability variation guarantee display. It may be displayed in pieces during the guarantee period.

  If the display control command decoded in step S714 of the display main control process (FIG. 36) is a falling lottery start effect command, the CPU 140 acquires each counter acquired in step S713. Among the values of C21 to C24, one of the five types of falling lottery start performance display is selected based on the value of the falling lottery start effect display determination counter C22, and this selection corresponds to the selected falling lottery start performance display. An effect image such as a character or background is displayed on the image display unit 30a or 30b by the VDP 143.

  In other words, after the display control circuit 111 receives the falling lottery start effect command for the special symbol display device 6a or 6b from the main control circuit 44, the CPU 140 next determines the falling lottery start effect display at the timing when the CPU 140 receives the interrupt signal from the VDP 143. The value of the counter C22 (random number 22, 0 to 99) is acquired, and one of the five types of falling lottery start effect displays is determined and displayed on the image display unit 30a or 30b. Thereby, the uniformity and irregularity of the numerical values acquired by the falling lottery start effect display determination counter C21 are ensured, and when the falling lottery start effect display is displayed on the image display unit 30a or 30b, the falling lottery start effect is displayed. Uniformity and irregularity of the contents of the display are guaranteed, and the gaming property of the gaming machine 1 is improved.

  Although the content of the fall lottery start effect display is not particularly limited, it is directly or indirectly (suggestive) that the special symbol display device 6a or 6b starts the lottery to drop the big hit probability from a high probability. For example, the image may include an image including characters such as “may fall!” “May start a lottery!” “No big deal!” “Okay, high probability!” “Surely come!”. Further, the drop lottery start effect display is an image display in which the slot game is displayed immediately after the last slot game in the probability variation guarantee period displayed on either the image display unit 30a or 30b is ended. It is displayed on the part 30a or 30b.

  When the display control command decoded in step S714 of the display main control process (FIG. 36) is a probability change fall effect command, the CPU 140 acquires each counter C21 acquired in step S713. Among the values of .about.C24, one of the five types of probability variation fall effect display is selected based on the value of the probability variation fall effect display determination counter C23, and the character, background, etc. corresponding to the selected probability variation fall effect display. The effect image is displayed on the image display unit 30a or 30b by the VDP 143.

  That is, after the display control circuit 111 receives the probability change fall effect command for the special symbol display device 6a or 6b from the main control circuit 44, the CPU 140 next receives the interrupt signal from the VDP 143 and the probability change fall effect display determination counter. The value of C23 (random number 23, 0 to 99) is acquired, and one of the above-described five kinds of probability variation fall display is determined and displayed on the image display unit 30a or 30b. Thereby, the uniformity and irregularity of the numerical value acquired by the counter C23 for determining the probability change fall effect display are ensured, and accordingly the content of the probability change fall effect display is displayed when the probability change fall effect display is displayed on the image display unit 30a or 30b. Thus, the uniformity and irregularity of the gaming machine 1 are guaranteed, and the gaming property of the gaming machine 1 is improved.

  Note that the content of the probability change fall display is not particularly limited, but the special symbol display device 6a or 6b directly or indirectly (implicitly) indicates that the big hit probability has fallen from a high probability, for example, It may be an image including characters such as “probable fall!” “May have fallen!” “May not be a lottery for fall!” “Why! In addition, this probability change fall display is an image display in which the slot game is displayed immediately after the last slot game with a high probability of jackpot displayed on the image display unit 30a or 30b is finished. It is displayed on the part 30a or 30b.

  When the display control command decoded in step S714 of the display main control process (FIG. 36) is a fall probability change effect command, the CPU 140 obtains each counter acquired in step S713. Among the values of C21 to C24, one of five types of fall probability change effect displays is selected based on the value of the fall probability change effect display determination counter C24, and corresponds to the selected fall probability change effect display. An effect image such as a character or background is displayed on the image display unit 30a or 30b by the VDP 143.

  That is, after the display control circuit 111 receives the fall probability change effect command for the special symbol display device 6a or 6b from the main control circuit 44, the CPU 140 next determines the fall probability change effect display at the timing when the CPU 140 receives the interrupt signal from the VDP 143. The value of the counter C24 (random number 24, 0 to 99) is acquired, and one of the five types of fall probability change effect displays is determined and displayed on the image display unit 30a or 30b. Thereby, the uniformity and irregularity of the numerical value acquired by the fall probability change effect display determination counter C24 are ensured, and therefore when the fall probability change effect display is displayed on the image display unit 30a or 30b, the fall probability change effect is produced. Uniformity and irregularity of the contents of the display are guaranteed, and the gaming property of the gaming machine 1 is improved.

  The content of the fall probability change effect display is not particularly limited, but the probability of the fall lottery between the special symbol display device 6a and the special symbol display device 6b is set to be exchanged so that the jackpot probability falls from a high probability. It may be an image including a character or the like that directly or indirectly (implicitly) indicates that the probability of winning is changed. For example, when the falling lottery is executed in any one of the special symbol display devices 6a and 6b, the image display unit 30a or 30b in which the falling lottery is executed displays “Are!” And “Change the falling probability!” An image including characters such as “falling probability increase!” And “falling probability decrease!” May be displayed. If both of the special symbol display devices 6a and 6b are falling lotteries, an image display unit is displayed. Images including characters such as “Aim at the start winning opening 11a (start winning opening 11b)!”, “Change the way to strike!” And “Right strike (left strike)!” May be displayed on 30a and 30b.

  In addition, this drop probability change effect display is the last slot game before the probability of the drop lottery displayed on either the image display unit 30a or 30b where the drop lottery is executed, that is, plus or minus one symbol. The reach-out symbols are displayed on the image display unit 30a and / or 30b just after the slot game related to the reach-out is finished. In this case, the drop probability change effect display is displayed on the image display section 30a or 30b on which the slot game related to the reach loss is displayed when the drop lottery is executed by only one of the special symbol display devices 6a and 6b. When both of the special symbol display devices 6a and 6b are displayed, the lottery is displayed on the image display units 30a and 30b almost simultaneously (when the slot game related to the reach deviation is displayed, When one of the image display units 30a or 30b is in a slot game, it may be displayed so that the player can see it in a slot game or over a display area, as described above. It may be displayed after the slot game is finished).

  Further, the probability variation guarantee effect display, the falling lottery start effect display, the probability variation fall effect display, and the fall probability change effect display need not be described, and the effect images using various characters and various backgrounds are special symbol display devices 6a, 6b, which is displayed on the image display units 30a and 30b. The player directly or indirectly (suggestively) expresses the intention of the effect display depending on the type and movement of the character or the type and color of the background image. It has come to appeal to. In addition to the above-described characters, for example, voice may be used together with these effect displays, or LEDs and lamps provided in the gaming machine 1 may be simultaneously turned on or blinked. In addition, a predetermined character or the like may be randomly displayed in the effect display by lottery or the like by random number processing or the like. If it does in this way, the effect of an effect display will increase further and the interest of a game will increase.

  If the display control command decoded in step S714 of the display main control process (FIG. 36) is a command for instructing display of the big hit effect image for the special symbol display device 6a or 6b, the CPU 140 Causes the VDP 143 to display an effect image such as a character or background corresponding to the big hit effect image on the image display unit 30a or 30b.

  Further, the display control command decoded in step S714 of the display main control process (FIG. 36) is a fluctuation pattern (fluctuation patterns 21, 22,. 31, 32, 4, 51, 52, 61, 62) In the case of a designation command, the CPU 140 displays an effect image such as a character or background corresponding to each reach variation pattern by the image display unit 30 a or 30 b using the VDP 143. To display.

  Next, a specific game flow of the gaming machine 1 executed based on the above-described main game process, display main control process, and the like will be described with reference to FIGS. 41 and 42. FIG. 41 shows that the special symbol display device 6a is confirmed and displayed on the special symbol display device 6a until the jackpot probability related to the special symbol display device 6a rises to a high probability and then falls to the normal probability again (special symbol display device 6a). FIG. 42 is an explanatory diagram showing the flow of the game in the case where only the falling lottery relating to (i) is executed, and FIG. 42 shows that the special symbol display device 6a, 6b is confirmed and displayed, and the special symbol display device 6a, An explanation showing the flow of the game from when both of the big hit probabilities relating to 6b rise to a high probability until one falls to a normal probability (when the falling lottery relating to the special symbol display devices 6a and 6b is simultaneously executed) FIG.

  First, referring to FIG. 41, a game ball launched from the hitting ball launching device 43 to the game area 5 on the game board 21 by winning the player's hitting operation handle 2 wins the start winning holes 11a and 11b. As a result of the winning, a slot game for scrolling the special symbols in a predetermined direction is displayed on the image display units 30a and 30b of the special symbol display devices 6a and 6b. While the slot game related to these winnings is displayed in a predetermined variation pattern on the image display units 30a and 30b, if one game ball wins in the start winning opening 11a, the hold LED 25a is turned on, while the game is played. When one ball enters the start winning opening 11b, the hold LED 29a is turned on. Thereafter, the hold LEDs 25b, 25c, 25d or the hold LEDs 29b, 29c, 29d are sequentially turned on each time one game ball wins the start winning opening 11a or 11b. After that, even if a game ball wins the start winning opening 11a or 11b after that, it becomes an overflow ball and is not stored as a holding ball.

  When the slot game displayed on the image display section 30a or 30b is finished and a predetermined symbol is confirmed and displayed as a combination of special symbols, one corresponding hold LED 25 or 29 is turned off (hold LED 25d, 25c, 25b, 25a or hold LEDs 29d, 29c, 29b, 29a are turned off in this order), and the next slot game is started again on the image display unit 30a or 30b. Thereafter, in the gaming machine 1, when the game ball wins the start winning opening 11a or 11b, the game related to the special symbol is repeated in this way.

  In the image display units 30a and 30b, when the special symbols of the left symbol display units 8a and 8b and the special symbols of the right symbol display units 10a and 10b are a combination of the same special symbols, reach is performed, and a predetermined reach action is performed. Is displayed (variation patterns 21, 22, 31, 32, 4, 51, 52, 61, 62, special symbol variation time T = 13 to 42 seconds). If it becomes a three-digit double-digit number symbol), it will be a big win, and as described above, the attackers as the big winning openings 7a, 7b are opened in a predetermined manner (when the big win is made in the image display section 30a, it is a big win) The jackpot game (denoted as 16R jackpot game in FIG. 41) is executed, and the other combinations of special symbols are as follows: The LES (variation pattern 1, the special symbol variation time T = 7 seconds). In addition, as described above, the reach deviation that is lost after reaching the reach includes the reach loss of the plus / minus 1 symbol and the reach failure other than the plus / minus 1 symbol. The related reach action has a very high production effect (the so-called super hot).

  On the other hand, the game ball passes through the normal symbol operation gates 19a and 19b, and by this passage, the normal symbol display devices 18a and 18b start to display a one-digit normal symbol variation display (normal symbol variation time t = 30 seconds). While the change display of the normal symbol related to the passage is displayed in a predetermined manner on the normal symbol display devices 18a and 18b, when one game ball passes through the normal symbol operation gates 19a and 19b, the hold LEDs 26a and 31a are displayed. After that, the hold LED 26b, 26c, 26d or 31b, 31c, 31d is sequentially turned on each time one game ball passes through the normal symbol operation gate 19a or 19b, and thereafter, the game ball operates normally. Even if it passes through the gates 19a and 19b, it becomes an overflow ball and is not stored as a pass-through ball.

  When the normal symbol change display displayed on the normal symbol display devices 18a and 18b is finished and a predetermined normal symbol is fixedly displayed, one corresponding hold LED 26, 31 is turned off (hold LED 26d, 26c, 26b, 26a or 31d, 31c, 31b, 31a in this order), and the normal symbol display devices 18a, 18b again start displaying the next normal symbol variation. Thereafter, in the gaming machine 1, when the game ball passes through the normal symbol operation gates 19a and 19b, the game related to the normal symbol is repeated in this way. Thus, when the normal symbol confirmed and displayed on the normal symbol display devices 18a and 18b becomes a winning symbol ("7"), it becomes a hit and, as described above, the blades of the start winning holes 11a and 11b are opened for a predetermined time. The winning prize opening 11a when hitting with the normal symbol display device 18a and the starting winning opening 11b when hitting with the normal symbol display device 18b, the starting winning device opening time ST = 0.2 seconds) Is executed.

  Then, when the game related to the special symbol and the normal symbol is repeated in this way, as shown in FIG. 41, the special symbol display symbol (big hit) is displayed on the image display unit 30a of the special symbol display device 6a as a result of the slot game. In the case where the odd-numbered symbol of the odd number among the symbols) is confirmed and displayed, the jackpot probability related to the special symbol display device 6a increases after the 16R jackpot game ends. In other words, the probability of a big hit relating to the special symbol display device 6a increases from 1/315 to 5/315 by changing the contents of the big hit determination counter C1 (random numbers 1, 0 to 314). Accordingly, when the probability of winning a big hit relating to the special symbol display device 6a is increasing, the probability of winning a big hit in the special symbol display device 6a is drastically improved, that is, when the specific big win symbol is confirmed and displayed on the special symbol display device 6a. The game related to the special symbol display device 6a is extremely advantageous for the player. Accordingly, the player can skillfully operate the hitting operation handle 2 to win the game ball in the start winning opening 11a, and can intervene in the game by using his / her skill, and in the course of the falling game ball. I will be angry.

  In the big hit game, a large number of game balls win the big prize opening 7a, and the player can acquire a large amount of prize balls. During the big hit game, the special symbol display device 6a has a big hit effect. An image is displayed, and during that time, even if a game ball wins at the start winning opening 11a, it becomes a holding ball and no slot game is played. Therefore, the maximum four holding balls related to the special symbol display device 6a (holding LEDs 25a, 25b) , 25c and 25d are all in a lighted state).

  At the same time when the big hit game is finished and the big hit probability is increased, the game state display is changed from “normal” to “probable change” which means that the big hit probability is increased from “normal”. The display of the device 32b is switched and displayed from “normal” to “guaranteed” which means that a lottery lottery is not performed and the big hit probability is maintained at a high probability.

  Now, referring to FIG. 41, when the big hit game is finished, in the special symbol display device 6a, the slot game corresponding to the held ball stored during the big hit game is turned off four times in response to the turn-off from the hold LED 25d. Is executed (denoted as a hold start during a big hit in FIG. 41), and during this hold start during a big hit, the increased jackpot probability does not decrease, that is, during the hold start during a big hit, the jackpot probability decreases. The winning lottery is not performed, and a high probability is guaranteed for the jackpot probability (described as “probability guarantee” in FIG. 41), and “probability change” and “guarantee” are continuously displayed in the gaming state display devices 32a and 32b during this period. Is displayed.

  In addition, when a hold start during a big hit is started, a probability variation guarantee display is displayed on the image display unit 30a. During this period, it is directly confirmed that the lottery lottery is not performed and the big hit probability is maintained at a high probability. Directly or indirectly (indicatively) produce display. This probability variation guarantee display is displayed by randomly selecting one of five types. Therefore, the player can make a jackpot probability of the special symbol display device 6a by the “probability change” and “guarantee” display of the game state display devices 32a and 32b and the probability change guarantee effect display of the image display unit 30a during the holding start during the big hit. It is possible to recognize or predict that the game is maintained with a high probability and face a game with great expectation (becoming a so-called daisy chain), and the willingness to play increases.

  Then, when the period of the on-hold start during the jackpot ends, that is, when the four slot games are ended on the special symbol display device 6a after the end of the jackpot game, the falling lottery starts, and the game ball wins at the start winning opening 11a. Thus, the lottery for determining whether or not the big hit probability falls from the high probability (5/315) to the low probability (1/315) is executed each time in the subsequent slot game of the special symbol display device 6a. When the falling lottery is started, the display of the game state display device 32a displays “probability change” as it is, and the display of the game state display device 32b changes from “guarantee” to the special symbol display device 6a. It is displayed by switching to “falling probability 1/100” meaning that it is performed with a probability of 100 (based on the case where 0 is set in the exchange flag F6).

  Also, when the falling lottery is started, a falling lottery start effect display is displayed on the image display unit 30a, and the period in which the big hit probability after the big hit game is guaranteed with a high probability ends. Directly or indirectly (implicitly) display that the falling lottery is started. The falling lottery start effect display is displayed by randomly selecting one of five types.

  Accordingly, the player is assured of a high probability of jackpot after the jackpot game is finished in the special symbol display device 6a by the “probability change” display of the game state display device 32a and the falling lottery start effect display of the image display unit 30a. Recognizing or predicting that the lottery will start from the current slot game and that the period is over, you can face the game with both expectations and anxiety, and make appropriate decisions to continue the game It becomes like this.

  Then, with the game state display device 32a displaying “probability change” and the game state display device 32b displaying “falling probability 1/100”, the special symbol display device 6a will now reach the plus or minus one symbol. When (variation pattern 21, 31, 51 or 61) is confirmed and displayed, the probability of falling lottery from the slot game in the next special symbol display device 6a is changed to 1/200. When the probability of the falling lottery of the special symbol display device 6a is changed, the display of the gaming state display device 32a displays “probability change” as it is, and the display of the gaming state display device 32b starts from “falling probability 1/100”. The special symbol display device 6a is switched to “falling probability 1/200” which means that the falling lottery is performed with a probability of 1/200.

  Further, when the probability of the falling lottery of the special symbol display device 6a is changed, a drop probability changing effect display is displayed on the image display unit 30a, and from the slot game executed on the special symbol display device 6a thereafter, until now. The fact that the probability of the falling lottery between the special symbol display device 6a and the special symbol display device 6b that has been set is exchanged and the probability of winning the lottery that falls from the high probability is changed has been changed directly or indirectly. Produce display (implicitly). This fall probability change effect display is displayed on the image display unit 30a immediately after the end of the slot game in which the symbol of the plus or minus 1 symbol is deviated and displayed on the special symbol display device 6a. Any one of the five types is randomly selected and displayed.

  Therefore, the player has great interest in the slot game related to the loss of reach, that is, the variation pattern of the special symbol to be displayed and the combination of the special symbol to be confirmed, and the “falling probability 1/200” of the gaming state display device 32b. "And the fall probability change effect display of the image display unit 30a recognize or predict that the probability of the drop lottery of the special symbol display device 6a has been advantageously changed for itself, and high expectations (the big hit probability is difficult to fall) It becomes easier to win big hits), and the game motivation increases.

  Referring to FIG. 41, the special symbol display device 6a is now plus or minus with “probability change” displayed on the game state display device 32a and “falling probability 1/200” displayed on the game state display device 32b. When the symbol out of reach (fluctuation pattern 21, 31, 51 or 61) is confirmed and displayed, the probability of the falling lottery related to the slot game of the special symbol display device 6a is changed to 1/100 as described above. Then, the display of the game state display device 32b is switched from “falling probability 1/200” to “falling probability 1/100”, and the fall probability change effect display is displayed on the image display unit 30a.

  Then, when the slot game is finished on the special symbol display device 6a in this gaming state, if it is determined that the winning lottery is won and the jackpot probability is to be dropped from a high probability (denoted falling confirmed in FIG. 46), this falling After the lottery is completed, the probability of winning the game by changing the contents of the jackpot determination counter C1 (random numbers 1, 0 to 314) from the next slot game in the special symbol display device 6a is reduced from 5/315 to 1/315. To do. Then, the display of the game state display device 32a is switched from “probability change”, and the display of the game state display device 32b is switched from “fall probability 1/100” to “normal” which means a normal game state. That is, this gaming state is the same as the normal gaming state before the big win in the special symbol display device 6a.

  Further, in this case, the probability change fall display is displayed on the image display unit 30a, and direct or indirect (suggestive) display that the jackpot probability related to the special symbol display device 6a has fallen from a high probability. . In this probability change fall display, any one of five types is randomly selected and displayed.

  Accordingly, the player has a high probability of winning big hits from the slot game started on the special symbol display device 6a thereafter by the “normal” display of the game state display devices 32a and 32b and the probability change fall display of the image display unit 30a. Falling from the probability, it can be recognized or predicted that the big jackpot lottery of the special symbol display device 6a will be performed with a normal jackpot probability, but although it is disappointing, on the other hand, it is determined appropriately whether to continue the game Will be able to.

  It should be noted that the special symbol display device 6a is confirmed and displayed in this manner, and during the game from when the jackpot probability related to the special symbol display device 6a rises to a high probability until it falls again to the normal probability, In the symbol display device 6b, the slot game is executed based on the winning of the game ball in the start winning opening 11b as usual, irrespective of the game related to the special symbol display device 6a. Accordingly, the display of the game state display devices 33a and 33b is performed. During this time, “normal” and “normal” are displayed as shown in FIG.

  Then, the jackpot probability related to the special symbol display device 6a falls from a high probability, and in the normal gaming state before the gaming state becomes a jackpot, based on the winning of the game ball to the start winning opening 11a, 11b Both of the special symbol display devices 6a and 6b play the slot game simultaneously, and this gaming state is maintained until the specific big symbol is confirmed and displayed on either the image display unit 30a or 30b. If the specific big symbol is confirmed and displayed, the game will proceed in the same manner as described above.

  Next, referring to FIG. 42, the special symbol display devices 6a and 6b are confirmed and displayed on the special symbol display devices 6a and 6b. The flow of the game until it falls to the probability of (when the falling lottery relating to the special symbol display devices 6a and 6b is executed simultaneously) will be described. In the description of FIG. 42, portions overlapping with FIG. 41 are omitted or described briefly.

  Now, referring to FIG. 42, as described in FIG. 41 above, when the special symbol display device 6a is confirmed and displayed, and the 16R jackpot game ends and the jackpot probability rises, the gaming state display device 32a, 32b is switched from “normal”, “normal” to “probability change”, “guarantee”, and a probable change guarantee effect display is displayed on the image display unit 30a, and the special symbol display device 6a stored during the 16R big hit game A slot game in which the jackpot probability corresponding to the holding ball is guaranteed with a high probability is executed four times. Then, when the special symbol display device 6b confirms and displays the specific big win symbol while the special symbol display device 6a guarantees the big hit probability with a high probability, this specific big win symbol is now confirmed. The 16R big hit game in which the big winning opening 7b is controlled to be converted into a predetermined mode based on the display is similarly executed.

  Then, while the special symbol display device 6b is displaying the big hit effect image based on the big hit game, the special symbol display device 6a starts the lottery when the slot game in which the big hit probability is guaranteed with a high probability is finished. The display of the status display device 32b is switched from “guarantee” to “falling probability 1/100”, and a falling lottery start effect display is displayed on the image display unit 30a.

  On the other hand, in the special symbol display device 6b, when the 16R big hit game is ended while the special symbol display device 6a is running the falling lottery, the big hit probability related to the special symbol display device 6b is increased, and the gaming state display device 33a, 33b is switched from “normal”, “normal” to “probability change”, “guarantee”, and a probable change guarantee effect display is displayed on the image display unit 30b, and the special symbol display device 6b stored during this 16R jackpot game is displayed. A slot game in which the jackpot probability corresponding to the reserved ball is guaranteed with a high probability is executed four times. In the gaming state in which the big hit probability is guaranteed with a high probability, the probability of falling lottery related to the special symbol display device 6b is set to 1/200.

  Then, while the special symbol display device 6b is executing the slot game in which the big hit probability is guaranteed with a high probability, when the special symbol display device 6a displays the reach-and-decrease symbol of plus or minus one symbol, the next time The probability of falling lottery from the slot game in the special symbol display device 6a is changed to 1/200, and the display of the game state display device 32b is switched from “falling probability 1/100” to “falling probability 1/200”. At the same time, the fall probability change effect display is displayed on the image display unit 30a. On the other hand, when the reach symbol of plus or minus 1 symbol is confirmed and displayed on the special symbol display device 6a in this way, the probability of the falling lottery relating to the special symbol display device 6b is also changed to 1/100. The display devices 33a and 33b maintain the display of “probability change” and “guarantee” as they are, and the drop probability change effect display is not displayed on the image display unit 30b.

  Then, when the slot game in which the big hit probability is guaranteed with a high probability has been completed on the special symbol display device 6b, the falling lottery is started, and the display on the gaming state display device 33b is changed from “guaranteed” to “fall probability 1/100. ”And a fall lottery start effect display on the image display unit 30b. That is, in this gaming state, the special symbol display devices 6a and 6b are simultaneously subjected to the falling lottery, the gaming state display device 32b has “falling probability 1/200”, and the gaming state display device 33b has “falling”. "Probability 1/100" is displayed, so that the player can use his / her skill to intervene in the game in order to win the game ball in the start winning opening 11a advantageous to him / her. Will improve.

  In this gaming state, when the special symbol display device 6a is again displayed on the special symbol display device 6a, the probability of falling lottery from the slot game in the next special symbol display device 6a is changed to 1/100. It is set and the display of the game state display device 32b is switched to “falling probability 1/100” and displayed, while the fall probability changing effect display is displayed on the image display unit 30a, while the special symbol display device 6b plays the slot game. If the slot game is being played on the special symbol display device 6b, the probability of the falling lottery relating to the special symbol display device 6b is reduced to 1/200 after the slot game is finished. After that, the display on the game state display device 33b is switched to “falling probability 1/200” and displayed on the image display unit 3 b To view the fall probability changing effect display.

  Therefore, the player has a great interest in the slot game related to the loss of reach, that is, the variation pattern of the special symbol to be displayed and the combination of the special symbol to be confirmed, and the “falling probability 1/100” of the gaming state display device 32b. The probability of falling lottery of the special symbol display devices 6a and 6b has been changed by the “falling probability 1/200” display of the display and gaming state display device 33b and the falling probability change effect display of the image display units 30a and 30b. This time, the adjustment of the launch of the game ball is changed in order to win the game ball in the start winning opening 11b, that is, to demonstrate the skill of the player and intervene in the game. And the game taste is further improved.

  Then, in this gaming state, when the special symbol display device 6b is now displayed with the plus / minus one symbol out of reach, the probability of the falling lottery relating to the special symbol display devices 6a and 6b is also reduced to 1/200. 1/100 is set to change, and the display of the game state display devices 32b and 33b is switched to “falling probability 1/200” and “falling probability 1/100”, and the fall probability changing effect is displayed on the image display units 30a and 30b. Display the display. Therefore, the player will change the adjustment of the launch of the game ball in the same way and technically intervene in the game in order to win the game ball in the start winning opening 11a.

  Then, when the slot game is finished on the special symbol display device 6a in this gaming state, if it is decided to win the fall lottery and the big hit probability falls from a high probability, the fall lottery is finished and the next special symbol is finished. The jackpot probability is reduced from the slot game on the display device 6a. Then, the display of the gaming state display device 32a is switched from “probability change”, the display of the gaming state display device 32b is switched from “falling probability 1/200” to “normal” which means a normal gaming state, respectively, and an image display unit A probability change fall effect display is displayed at 30a. That is, in this gaming state, the falling lottery is executed only on the special symbol display device 6b, and “probability change” is displayed on the gaming state display device 33a, and “falling probability 1/100” is displayed on the gaming state display device 33b. Therefore, the player can demonstrate his / her skill and intervene in the game in order to win the game ball in the start winning opening 11b which is advantageous to him / her, and the game taste is improved. The subsequent games are performed according to the game flow of FIG.

  In this way, with reference to FIG. 41 and FIG. 42, the flow of the game from when the specific big hit symbol is confirmed and the jackpot probability rises to a high probability and falls to the normal probability again has been described. As the game progresses as described above, the specific big symbol as a result of the slot game is finally displayed on the image display units 30a and 30b of the special symbol display devices 6a and 6b. The game is continued in accordance with the game flow of FIG. 41 or FIG. On the other hand, when the normal big win symbol is confirmed and displayed as a result of the slot game, after the big hit game is finished, the slot game is played in the normal game state until the next big hit.

  As described above, in the gaming machine 1 of the present embodiment, a plurality of special symbol display devices 6a and 6b, a plurality of start winning ports (electric tulips) 11a and 11b, and a plurality of large winning ports (attackers) 7a. , 7b are arranged on the game board 21, and a slot game is played in the special symbol display device 6a for winning in the start winning opening 11a and in the special symbol display device 6b for winning in the starting winning port 11b. When the special symbol display device 6a or 6b is confirmed and displayed on the special symbol display device 6a or 6b, the jackpot probability related to the special symbol display device 6a or 6b fluctuates with a high probability after the jackpot game ends. Then, when the falling lottery is performed, and when the special symbol display device 6a or 6b wins the falling lottery, the big hit probability related to the special symbol display device 6a or 6b won the falling lottery There has so as to change to a low probability. In other words, the probability variation (increase or decrease) of the big hit probability and the start and end of the falling lottery are individually executed by the special symbol display devices 6a and 6b, and depending on the timing, these big hit games and The falling lottery can be generated at the same time. Therefore, in such a gaming machine 1, a player can enjoy two games at the same time in parallel with one gaming machine 1, that is, it is possible to acquire a big hit game at the same time. As a result, the game preferences are greatly improved.

  In addition, since both the special symbol display devices 6a and 6b simultaneously display the slot game in parallel based on the winning of the game ball at the start winning opening 11a and 11b, the slot game can be quickly digested. Thus, the occurrence of overflow spheres can be reduced. Therefore, the number of times the slot game is consumed per unit time increases, and as a result, the probability of winning the player's jackpot is improved, so that the gaming property of the gaming machine 1 is improved.

  In addition, since the occurrence of overflow balls can be reduced, the cumbersome stopping operation of intermittently stopping the hitting ball launching device 43 that launches the game balls to the game area 5 is reduced so that the player does not generate overflow balls. As a result, the gameability of the gaming machine 1 is further improved, and the operating rate of the gaming machine 1 is increased for the game arcade, leading to an increase in sales.

  Further, in the present embodiment, the jackpot probability rises with probability fluctuations based on the specific big win symbol being confirmed and displayed. In the gaming state in which the jackpot probability has increased, the special symbol display device 6a. 6b, every time the slot game is executed, a falling lottery for determining whether or not the increased jackpot probability is to be dropped with a low probability is performed. Therefore, according to the gaming machine 1 having such a configuration, the gaming machine in which the jackpot probability is unconditionally maintained until the next next jackpot occurs or until a predetermined number of slot games are executed. Compared to, so-called continuous change that continuously generates big hits while maintaining a high probability of big hits is moderately prevented, and as a result, it is possible to improve the interest of the game while moderately reducing gambling It becomes.

  In addition, when the special symbol display devices 6a and 6b are simultaneously performing a lottery drawing, the probability of the falling lottery relating to the slot game of the special symbol display device 6a executed based on the winning of the game ball at the start winning opening 11a. And the probability of the falling lottery related to the slot game of the special symbol display device 6b executed based on the winning of the game ball at the start winning opening 11b are set differently, and a predetermined game condition is established (special Since either the symbol display device 6a or 6b is set to change when the symbol of the plus or minus 1 symbol is deviated and the symbol is confirmed and displayed, the player can set the game winning ball 11a or In order to win 11b, he can demonstrate his skill and intervene in the game, and as a result, he is disappointed at the whereabouts of the game ball falling on the game board 21. Interest of the machine 1 is increased.

  In particular, when a predetermined game condition is satisfied and the probability of falling lottery is changed, the player can hit the ball control handle 2 in a timely manner according to the positions of the start winning holes 11a and 11b provided on the game board 21. It is necessary to adjust the firing strength of the game ball fired from the hitting ball launching device 43 by operating the same, and this is the same when it hits, that is, hitting the normal symbol display device 18a. When the symbol is confirmed and displayed, the start winning port 11a hits the normal symbol display device 18b, and when the symbol is confirmed and displayed, the starting winning port 11b is opened. There is an effect.

  Furthermore, when the falling lottery is being performed, the effect image is displayed on the special symbol display devices 6a and 6b as information related to the game state, or the characters are displayed on the game state display devices 32 and 33 in a timely manner. Is notified to the player. Therefore, the player can obtain information useful for executing the game, and as a result, can appropriately determine the current gaming state and predict the future development of the game. As a result, the playability is further improved.

  Further, in the present embodiment, the slot game of the special symbol display device 6a is executed based on the fact that a game ball has won the start winning opening 11a, and the slot game of the special symbol display device 6b is played at the start winning opening 11b. The LED units 24a (holding LED 25) and 24b (holding LED 29) are provided for displaying the number of stored balls stored in the start winning ports 11a and 11b, respectively. Since it did in this way, the player can grasp | ascertain the progress of a game very easily, and, thereby, the game property of the gaming machine 1 improves.

  In the present embodiment, the special symbol display device 6a and the special symbol display device 6b are configured to share the display control circuit 111 including the CPU 140, the VDP 143, and the like, so that the parts cost of the gaming machine 1 is reduced. be able to.

  In the present embodiment, the means for dropping the big hit probability from the high probability, as described above, the individual lottery (probability change fall determination) in association with the execution of each slot game while the big hit probability is high. Counter C9 or C10), this may be performed by other lotteries (random numbers 1 to 8, 11, 12).

  In addition, the probability of falling lottery may be changed according to the character type. This will further improve the playability. The falling probability of changing the setting may be determined by lottery from a plurality of random numbers. If it does in this way, since it becomes possible to set a different fall probability whenever it changes, the interest of a game increases.

  The change of the lottery probability set for the falling lottery may be stopped, for example, when a predetermined number of slot games are executed, and after the stop, the stop may be released when the number of shot balls reaches a predetermined value. Furthermore, this stop release is won by a stop release lottery based on a predetermined random number process (a predetermined lottery probability) performed for each slot game due to, for example, winning of the game ball at the start winning holes 11a and 11b. In some cases, it may be executed.

  In addition to the above, the probability of the falling lottery may be reduced, for example, when the number of reserved balls exceeds a predetermined number while the probability of big hits is high, or falls in proportion to the number of reserved balls increasing. You may make it reduce the probability of a lottery. In this way, the player does not make the above-mentioned stop to prevent the occurrence of an overflow ball in order to reduce the probability of falling lottery. As a result, the operating rate of the gaming machine 1 is improved, This will lead to improved sales at the amusement hall.

  Alternatively, the decrease or increase of the probability of falling lottery may be performed in accordance with an instruction regarding a predetermined game. For example, the display of the image display units 30a and 30b of the special symbol display devices 6a and 6b and the sound from the speaker 113 The probability of falling lottery is increased by following an instruction to win a game ball to a winning device other than the predetermined start winning holes 11a and 11b, an instruction to make a specific number of reserved balls, etc. In this way, the player adjusts the hitting ball launching device 43 that launches the game ball to the game area 5 in order to develop the game advantageously, and the designated winning device and the start winning ports 11a and 11b are adjusted. The game ball must be awarded to the player, and the sense of technical intervention in the game is further increased, thereby improving the taste of the game.

  Further, the probability of falling lottery may be reduced or increased based on the predetermined symbol displayed as a normal symbol, for example, based on the fact that “5” is fixedly displayed as a normal symbol. The probability of the falling lottery may be reduced, and the probability of the falling lottery may be returned to the original probability based on the fact that “2” is confirmed and displayed.

  In addition, the probability of falling lottery may be set to be different depending on the type of the specific bonus symbol.In this way, the player becomes very interested in the special symbol, and the specific bonus symbol that is confirmed and displayed. I was disappointed with the design, which also improved my gameplay. Alternatively, the probability of the falling lottery set may be set to be different in the lottery separately by a predetermined random number process or the like when the specific big win symbol is fixedly displayed instead of the specific big win symbol type. . In such a case, the probability of the falling lottery set for the player when the specific big win symbol is confirmed and displayed, or when the big hit game related to the specific big win symbol is finished, etc. It is good to notify so that you can understand.

  Further, when the probability of falling lottery is set to be different, the occurrence of the slot game in which the probability of falling lottery is set lower may be reduced. For example, if the special symbol display device 6a is set to have a lower probability of falling lottery than the special symbol display device 6b, the game ball winning to the start winning opening 11a is started by the arrangement of the obstacle nails. Making it more difficult than the winning opening 11b.

  Alternatively, the following may be performed as a means different from the obstacle nail. That is, both of the start winning ports 11a and 11b are provided integrally, and a normal type starting winning port with no change in starting port is formed as the starting winning port 11b in the upper portion thereof, and the starting winning port 11a is formed in the lower portion. Electric tulip-type start-up winning opening is formed. In the normal gaming state, only the normal type start winning opening 11b wins a game ball, and the electric tulip blades are opened only when the winning symbol is displayed on the normal symbol display devices 18a and 18b. The game ball is allowed to be awarded to the start winning opening 11a.

  This not only makes it difficult for the game ball to win the start winning opening 11a than the start winning opening 11b, but also reduces the installation space for the start winning opening. In this case, it is possible to increase the payout of prize balls of the start prize opening 11a which is harder to win than the start prize opening 11b (for example, five prize balls of the start prize opening 11a, the start prize opening 11b (3 prize balls), and further, it may be possible to increase the lottery probability that the normal symbol wins as the predetermined game condition is established, or to extend the start winning opening opening time ST.

  As a result, the player can further increase the sense of technical intervention in the game and improve the taste of the game. It is advantageous for the game, and the game taste is further improved.

  Further, in this way, the special symbol display device 6a is set to have a lower probability of the falling lottery than the special symbol display device 6b, and the winning of the game ball to the start winning opening 11a is more difficult than the starting winning opening 11b. In this case, the jackpot probability and the contents of the jackpot game related to the special symbol display device 6a may be made more advantageous to the player than the special symbol display device 6b. In this way, the player tries to win the game ball to the start winning opening 11a that is hard to win desperately. As a result, the feeling of technical intervention in the game is greatly increased, and the predetermined game condition as in the above embodiment is achieved. Is established and the probability of the falling lottery is switched, it is extremely advantageous for the player, and the game taste is greatly improved. In addition, as what makes the content of the big hit game advantageous or disadvantageous for the player, for example, the number of times of opening (the number of rounds), the prescribed number of winnings, or the number of prize balls of the big winning openings 7a and 7b may be different. In short, in this case, the jackpot game related to the special symbol display device 6a only needs to be able to acquire more game balls than the special symbol display device 6b.

  Or, if the special symbol display device 6a is set to have a lower probability of falling lottery than the special symbol display device 6b (the game ball winnings at the start winning holes 11a and 11b are equal), the special symbol display device 6a is special. The jackpot probability and the contents of the jackpot game related to the symbol display device 6a may be made more disadvantageous to the player than the special symbol display device 6b. In this way, the player himself decides which of the starting winning holes 11a and 11b should be awarded with the game ball, that is, which of the slot games performed in the special symbol display devices 6a and 6b is advantageous. The game starts after thinking, and this also improves the game taste.

  Further, the special winning openings 7 a and 7 b may be arranged above and below the game area 5. Here, the upper area of the game area may be within the upper third of the approximate game area 5, and the lower area of the game area may be within the lower third of the approximate game area 5. In this way, when the player wins a big hit, the player operates the hitting ball operating handle 2 in accordance with the positions of the big winning holes 7a and 7b arranged above and below the game area 5 to hit the hitting ball launching device 43. As a result, the player's own skill can be demonstrated and technical intervention can be made in the game, and the game machine's taste is improved.

  When the special symbol display devices 6a and 6b are both subjected to the falling lottery, the background colors of the image display units 30a and 30b of the special symbol display devices 6a and 6b may be different from each other. For example, a higher probability of falling lottery is blue, and a lower probability is red.

  In addition, when the jackpot probability is low due to the falling lottery, it is reduced to the jackpot probability of the normal gaming state, that is, the jackpot probability is dropped from 5/315 to 1/315 by the falling lottery. However, this may fall in stages. For example, the big hit probability may fall from 3/315 to 3/315 by the first falling lottery, and the big hit probability may fall from 3/315 to 1/315 by the second falling lottery. In addition, in the case of falling in stages as described above, it is preferable that the state such as the character or background is changed by changing the color of the character, the background, or the like according to the stay state of each stage so that the user can know in which state. .

  Furthermore, it is preferable to provide a probability setting means that can set the probability of the falling lottery to be set freely according to an operation from outside the gaming machine 1. Thus, if the probability of the falling lottery can be set freely according to the probability setting means of the gaming machine 1, the operating profit can be easily adjusted for the hall, and the player executes the game several times. It is possible to roughly know that this is an advantageous setting for the player, and technical intervention can be performed based on the knowledge.

  In addition, after the big hit probability fell to a low probability by the falling lottery, the big hit probability was maintained at a low probability until the big hit probability in the next specific big hit design, but this was after the big hit probability fell to a low probability When a predetermined number of slot games have been executed without a big hit, the big hit probability may be restored to a high probability again. In this case, the probability can be restored according to the type of the specific big symbol You may mix things and impossible things. If the number of slot games in the fall state is limited in this way, it is possible to rescue a player who is unlucky and the game performance is improved.

  Here, the predetermined number of slot games in this case is preferably as large as possible (for example, 1000 times). The reason for this is that it is not preferable for a game to easily return to a high probability once a big hit probability has fallen to a low probability. Because I want to. In addition, when the big hit probability is returned to a high probability in this way, the specific big hit symbol is confirmed and displayed, and in the same way as when the big hit probability becomes high immediately after the end of the big hit game, a predetermined number of times thereafter It is advisable to prohibit the falling lottery during the period until the slot game is executed. This is because it is not preferable that a player falls in a low probability due to a falling lottery as soon as the corner big hit probability becomes high, and the player's willingness to play declines. Accordingly, providing such a compulsory falling lottery prohibition period increases the interest of the game, and the player can face the game with great expectation during this period with peace of mind.

  In addition, when only one of the special symbol display devices 6a and 6b is a big hit, that is, when the big hit game relating to both the special symbol display devices 6a and 6b is not being executed at the same time, the big winning openings 7a and 7b. Both may be controlled in a predetermined manner so as to shorten the execution time of the big hit game while maintaining the number of game balls that the player acquires in the big hit game. As a predetermined mode of both the big winning openings 7a and 7b, for example, two rounds are simultaneously started (for example, the first round and the second round are started simultaneously, the first round is the big winning opening 7a, the second round is And advancing in accordance with the special winning opening 7b.

  In addition, all the above-mentioned effect displays are dummy displayed with a predetermined probability (preferably low probability) at the display timing (the effect display is displayed at the timing when the contents of the effect display and the gaming state do not match. (Pseudo effect display). In this case, it is preferable that the effect display not only directly but indirectly (to suggest). This is because it is not preferable to notify the player of the contents of the dummy effect display directly to the player because it becomes complete false information.

  For example, as a dummy effect display, an effect display that makes it difficult for the player to know whether the jackpot probability is high or low as the gaming state, or the jackpot probability falls to a low probability. In spite of the fact that there is a game state, it seems that the jackpot probability is high probability, and conversely, the big hit probability is high probability, but the game state seems to have dropped the jackpot probability to low probability There is an effect display that makes it appear as if it has been won in each lottery, an effect display that makes it appear that it has not been won, or vice versa. Therefore, the entertainment of the game is further increased by appropriately performing such dummy effect display.

  In addition, rarely, it is preferable to make an effect display such as the following contents appear instead of the probability change fall display. In other words, the contents of the effect display are given a story, and the effect is such that the jackpot probability gradually falls from a high probability (in this case, it may be spread over a plurality of slot games). The end of the event will be a branching to both a good result and a bad result. If the effect display has such contents, the player does not know whether the big hit probability is high probability or low probability as the gaming state, so this effect display is changed to a particularly probable fall effect display. When it appears, the player is not discouraged excessively, and the number of times that the game is stopped is reduced. As a result, the operating rate of the gaming machine 1 is improved.

  Further, in the present embodiment, when the specific big symbol is fixedly displayed, the jackpot probability is increased with a high probability. In addition to this, a predetermined big symbol is displayed after the specific big symbol is fixedly displayed. Until the number of times (for example, 100 times) of the slot game is exhausted or until the next big hit comes, the content of the winning judgment counter C11 is changed to increase the lottery probability that the normal symbol is won (for example, 10/31 to 28/31), shortening the normal symbol variation time t (for example, 30 seconds to 2 seconds), extending the start winning opening opening time ST (for example, 0.2 seconds to 2 seconds), special symbols The fluctuation time T may be shortened (for example, from 7 to 42 seconds to 2 to 37 seconds). Note that these processes may be executed other than when the specific big win symbol is confirmed and displayed, for example, for all big hit symbols, or while the big hit probability is rising, It may be executed when a big hit is made. In the latter case, even if a normal bonus symbol is played, processing that is advantageous to the player is executed a predetermined number of times, so that the player wins a big hit with the normal bonus symbol, for example. Even in such a case, it is possible to face the game without being excessively discouraged, that is, it is possible to give the player a suitable joyfulness, and as a result, the gameability is remarkably improved.

  Further, in the present embodiment, when both of the start winning ports 11a and 11b have reserved memory, the reserved memory related to either of the starting winning ports 11a or 11b may be preferentially digested. . In this way, the player's sense of technical intervention in the game is further increased, and the game taste is improved.

In the present embodiment, the special symbols and variation patterns related to the slot game displayed on the special symbol display devices 6a and 6b are the same, but they may be different.
In addition, the slot game related to the big hit and reach loss displayed on one of the special symbol display devices 6a and 6b may be enlarged and displayed only when the slot game related to the shift is displayed on the other side.
