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 performing a lottery drawing by variably displaying a predetermined symbol on an image display device.

  Conventionally, gaming machines have been devised in various ways to improve their taste. In particular, a gaming machine equipped with an image display device on a gaming area has various contrivances because the popularity and unpopularity of gaming machines are determined depending on how the display method of the image display device is devised. 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 sections for displaying symbols are set, and a pseudo pattern showing a state where a pattern, a character, a number, a symbol, a character, etc. as a special symbol is rotated on each symbol display section based on the winning of the 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 as 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. If a big hit with a big hit symbol (for example, odd-numbered flats) becomes a special game state advantageous to the player, such as a probability variation state in which the big hit probability (lottery probability) in the slot game 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 a prior art).
Japanese Patent Laid-Open No. 9-182846

  However, in such a conventional gaming machine with a probability variation function, a large amount of game balls are paid out when a specific jackpot symbol is generated, so the jackpot probability is inevitably set low for business purposes. ing. Therefore, the player can acquire a large number of game balls at a time when the player is in good condition, but on the other hand, the player may not be able to acquire a big hit as long as the player is in a bad condition.

When the slot game is displayed, the effect image displays that the jackpot probability is still rising.

  A gaming machine according to claim 16 is the gaming machine according to claim 15, wherein the number of times of the slot game is set based on the increased jackpot probability, and at least the increased jackpot It is characterized by being set larger than the reciprocal of the probability.

  A gaming machine according to claim 17 is the gaming machine according to any one of claims 14 to 16, wherein the control means includes a main control means and a display control means. Communication with the display control means is performed only in one direction from the main control means to the display control means, and the display control means receives the predetermined display command signal from the main control means, so that the effect image display is performed. The effect image is displayed on the image display device by means.

  The gaming machine according to claim 18 is the gaming machine according to claim 17, wherein a plurality of types of the effect images are provided, and the display control means receives the display command signal from the main control means. Based on the above, one of the plurality of types of effect images is selected by a predetermined random number process, and the selected effect images are displayed on the image display device.

  According to the first aspect of the present invention, for example, a game ball detection means such as a proximity sensor detects a winning or passing of a game ball at a start winning opening or an operation gate provided in a game area, and the game ball detection means Due to the detection of winning or passing, the control means performs a big hit lottery based on the set big hit probability, and at the same time, the image display device stops at least a predetermined symbol after the change and determines it. The slot game display based on the lottery is executed.

  As a result of the slot game, if the symbol that is confirmed and displayed on the image display device is a big hit symbol, for example, a predetermined symbol number (777) that is a predetermined value, it will be a big hit, and the special game generating means will be used for the player. Convert the variable prize-winning device that can be converted into an advantageous state and a disadvantageous state into a predetermined mode, for example, a state in which a game ball is easily received when it is open and a state in which a game ball is not received when it is closed A winning device such as a possible attacker is converted and controlled so as to repeatedly open a plurality of times for a predetermined time, thereby generating a special game advantageous to the player.

  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 together, 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 expresses in the form reflected in the display result of is also included.

  Similarly, if the symbol determined and displayed on the image display device is a specific symbol as a result of the slot game, the jackpot probability increasing means increases at least the jackpot probability. In this case, in addition to the increase in the 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, a gaming state is achieved in which it is advantageous for the player to acquire a special game.

  In such a gaming machine, when the big hit probability is raised by the big hit probability increasing means, the big hit probability reducing means reduces the rising big hit probability based on the establishment of the predetermined first game condition. . Further, the present invention is provided with a big hit probability lowering stop means, and the big hit probability lowering stop means stops the execution of the big hit probability lowering means based on the establishment of a predetermined second game condition.

  That is, in the present invention, when a specific symbol is fixedly displayed, the subsequent slot games are executed with an increased jackpot probability, but this increase is caused by the establishment of a predetermined first game condition. The jackpot probability is lowered. Therefore, when the jackpot probability is lowered, the subsequent slot games are executed with the lowered jackpot probability.

  Therefore, when the game is being executed with the increased jackpot probability, the predetermined first game condition is not satisfied, and if the predetermined second game condition is satisfied, the big hit probability is reduced by the big hit probability lowering stop means. The execution of the lowering jackpot probability reduction means is stopped, that is, when the jackpot probability lowering stop means is executed, the increased jackpot probability is maintained, and the subsequent slot game is executed with the increased jackpot probability. Therefore, the jackpot probability is not reduced.

  In the gaming machine according to the invention of claim 1 having the above-described configuration, both the jackpot probability lowering means and the jackpot probability lowering stop means are combined, so that when the jackpot probability increases, the jackpot probability increases. In some cases, big hits occur continuously with the state maintained, and a large amount of game balls are paid out to the player as prize balls in a short period of time. Therefore, while setting the probability of jackpot in normal gaming (the jackpot probability before rising) to be relatively high and averaging the number of prize balls per unit time, moderate euphoria This makes it possible to play games with reduced tension, and as a result, the taste of the gaming machine is greatly improved.

  By the way, there are various jackpot probability reduction means for stopping the execution of the jackpot probability reducing means for reducing the rising jackpot probability and the jackpot probability reduction stopping means for stopping the execution of the jackpot probability reduction means. That is, the gaming machine according to claim 2 is the gaming machine according to claim 1, wherein the big hit probability lowering means is a lottery with a reduced big hit probability that lowers the big hit probability that is rising based on a predetermined lottery probability. The gaming machine according to claim 3 is the gaming machine according to claim 1 or 2, wherein the big hit probability lowering stop means is executed based on a predetermined lottery probability. Is a lottery stop means for reducing the probability of winning a big hit. Thus, since the big hit probability lowering means and the big hit probability lowering stopping means are executed by lottery based on a predetermined lottery probability, therefore, according to the inventions of claim 2 and claim 3 having such a configuration, The interest of the game is improved, and it is possible to provide a suitable gaming machine regardless of beginner or expert.

  Further, in the gaming machine according to claim 4, in the gaming machine according to claim 3, the predetermined first gaming condition and the second gaming condition are the same condition, so the big hit probability decreasing lottery means and the big hit probability The reduction lottery stopping means is executed together. According to the invention of claim 4 having such a configuration, in addition to the effect of the invention of claim 3, there are two kinds of lotteries: a lottery for reducing the rising jackpot probability and a lottery for stopping the lottery for reducing the jackpot probability. Since the lottery will be executed together, as a result, the interest of the game is greatly improved.

  By the way, a predetermined first game condition for executing a lottery for reducing the rising jackpot probability and a predetermined second game condition for executing a lottery for stopping the lottery for decreasing the jackpot probability. Various establishments are conceivable, but this is preferably performed as follows. That is, the gaming machine according to claim 5 is the gaming machine according to claim 4, wherein when the game ball wins or passes through the start gaming device and the slot game is executed by the control means, a predetermined first gaming condition The gaming machine according to claim 6 is the gaming machine according to claim 5, wherein the big hit probability decreasing lottery means and the big hit probability decreasing lottery stop each time the slot game is executed. A lottery of means is performed.

  Since the slot game is a game in which a lottery is drawn based on the jackpot probability set as described above, as described in claim 5, the game ball wins or passes through the starting gaming device and the slot game is played. If a lottery for reducing the big hit probability and a lottery for stopping the lottery for reducing the big hit probability are performed as the establishment of the predetermined first game condition and the second game condition, it is related to the execution of the slot game. If the lottery for reducing the big hit probability and the lottery for stopping the lottery for reducing the big hit probability are performed, the lottery result can be immediately reflected in the slot game executed this time.

  For example, if it is decided to stop the lottery that reduces the jackpot probability as a result of the lottery, the lottery that lowers the jackpot probability may not be executed in the slot game that is executed this time, or the jackpot probability is reduced. Even if the lottery is executed, the lottery result may be invalidated in the slot game executed this time.

  Furthermore, since the timing at which the game ball wins or passes the starting game device is random, the lottery is used to reduce the big hit probability by using a random number or the like and to stop the lottery to reduce the big hit probability. In this case, the uniformity and irregularity of the lottery results are ensured. Further, as described in claim 6, if the lottery for reducing the jackpot probability and the lottery for stopping the lottery for decreasing the jackpot probability are performed every time the slot game is executed, the effect of the invention of claim 1 is further achieved. Can be conspicuous, and the playability is greatly improved.

  Further, the gaming machine according to claim 7 is the gaming machine according to any one of claims 3 to 6, wherein the game ball detection means includes a detection number storage means, and the detection number storage means comprises: The number of game balls that have won or passed through the starting game device but have not yet consumed the slot game is stored a predetermined number of times. The control means includes a slot game non-execution means. The slot game non-execution means does not accept a slot for winning or passing a game ball that has not been stored in the detection number storage means beyond the predetermined number of times. Do not run the game. This is because a game ball that was won or passed to the starting game device but was not stored in the number-of-detections storage means is a so-called overflow ball. If an overflow ball is generated, the slot game is not executed for winning or passing of the starting gaming machine related to the overflow ball.

  In such a gaming machine, when the number of game balls stored in the detection count storage means exceeds a predetermined number, or the number of game balls stored in the detection count storage means increases, the jackpot probability decreases. The lottery probability of the lottery means decreases or / and the lottery probability of the jackpot probability lowering lottery stop means increases. For example, if the maximum number of times of storage in the detection number storage means is 4, when the number of times of storage is 3 or more, the lottery probability of the jackpot probability lowering lottery means is reduced and / or the lottery probability of the jackpot probability lowering lottery stopping means In addition, for example, the lottery probability of the jackpot probability lowering lottery means is sequentially decreased or / and the lottery probability of the jackpot probability lowering lottery stopping means is increased in proportion to the increase in the number of times of memory from 1 to 2, 3, 4 times. It rises sequentially. Therefore, according to the invention of claim 7 having such a configuration, in addition to the effect of the invention of any of claims 3 to 6, the player reduces the lottery probability of the jackpot probability lowering lottery means or / and In order to prevent the occurrence of an overflow ball in order to increase the lottery probability of the jackpot probability lowering lottery stop means, so-called stop hitting (to intermittently fire a game ball by operating a ball hitting device) As a result, a sense of technical intervention in the game is increased, and the taste of the game is improved. Furthermore, the utilization rate of gaming machines will improve, leading to improved sales at the game hall.

  The conditions for lowering the lottery probability of the jackpot probability lowering lottery means and / or increasing the lottery probability of the jackpot probability lowering lottery stopping means may be changed to the condition described in claim 7 or in addition to the following. Good, that is, the gaming machine according to claim 8 is the gaming machine according to any one of claims 3 to 7, wherein the lottery of the big hit probability lowering lottery means and / or the big hit probability lowering lottery stopping means is executed. In this case, a game instruction notifying means for notifying an instruction regarding a predetermined game to the outside of the gaming machine is provided, and if the instruction of the game instruction notifying means is followed, the lottery probability of the big hit probability lowering lottery means is reduced or / and the big hit probability The lottery probability of the reduction lottery stopping means is increased. In addition, as an instruction regarding a game, for example, an instruction to win or pass a game ball to a predetermined winning device, an instruction to set the number of times stored in the detection number storage means to a specific number, or a predetermined number of symbol fluctuation times In addition, a predetermined reach or an instruction for causing a character to appear on the image display device can be considered, and examples of the notification means include display by the image display device described above and sound notification by a speaker or the like. Therefore, in the invention of claim 8, in addition to the effects of any one of claims 3 to 7, the player's sense of technical intervention in the game is further increased, and the game taste is improved.

  Further, in the gaming machine according to claim 9, in the gaming machine according to any one of claims 3 to 8, a plurality of types of specific symbols serve as jackpot symbols. In other words, a plurality of types of jackpot symbols are provided, and a predetermined plurality of types of jackpot symbols out of the plurality of types of jackpot symbols are set as specific symbols. In other words, the specific symbol also serves as a jackpot symbol that is of great interest to the player. The lottery probability of the jackpot probability lowering lottery means and / or the jackpot probability lowering lottery stopping means is lowered when a predetermined specific symbol is continuously displayed as a big hit symbol among a plurality of types of specific symbols. Or let it rise.

  For example, nine types of numerical symbols “1, 1, 1” to “9, 9, 9” of three digits are provided as a plurality of types of jackpot symbols, of which five types of odd numbers are selected as specific symbols. When the number symbol design of the eye is provided, when “7, 7, 7” is displayed on the image display device as the big hit symbol twice in succession (however, in the meantime, the number of symbols will be confirmed several times) May be displayed), the lottery probability of the jackpot probability lowering lottery means is decreased or / and the lottery probability of the jackpot probability lowering lottery stop means is increased, while “1, 1, 1” or “9, 9, When “9” is repeated twice, the lottery probability of the jackpot probability lowering lottery means is increased or / and the lottery probability of the jackpot probability lowering lottery stopping means is lowered (in this case, “9” is followed by “9”). , 9, 9 ”may be included)

  Therefore, according to the invention of claim 9 having such a configuration, in addition to the effect of any one of claims 3 to 8, the player can determine a specific symbol as a jackpot symbol continuously several times. Every time it is displayed, the lottery probability of the jackpot probability lowering lottery means and / or the jackpot probability lowering lottery stopping means becomes lower or higher, and as a result, the game taste is further improved.

  Further, the gaming machine according to claim 10 is the gaming machine according to any one of claims 3 to 9, further comprising lottery probability notification means, wherein the lottery probability notification means is a lottery probability reduction lottery means or / And the lottery probability of the jackpot probability lowering lottery stopping means is notified to the outside. Note that as the notification means, display by an image display device, notification of sound by a speaker, or the like can be considered as described above. Accordingly, in the invention of claim 10, in addition to the effects of any of claims 3 to 9, the player performs a lottery probability that the increased jackpot probability decreases or / and a lottery that decreases the increased jackpot probability. Since the lottery probability of stopping can be recognized, that is, it is possible to obtain extremely important information for continuing the game, and as a result, the game performance is greatly improved.

  Here, if the execution of the big hit probability lowering means is stopped without limit by the big hit probability lowering stop means, the big hit may occur continuously, and a large amount of game balls may be paid out in a short time. In such a case, it is better to do as follows. That is, the gaming machine according to claim 11 is a gaming machine according to any one of claims 1 to 10, wherein when the execution of the big hit probability lowering means is stopped by the big hit probability lowering stopping means, The probability reduction restarting means cancels the execution of the stopped big hit probability reducing means based on the establishment of the predetermined third game condition, and starts the execution of the big hit probability reducing means again. In relation to the invention of claim 4, when the big hit probability reducing means is restarted, the big hit probability reducing lottery stopping means is also executed together with the big hit probability reducing lottery means. Therefore, in the invention of claim 11, in addition to the effect of any of the inventions of claims 1 to 10, it is possible to appropriately suppress the euphoria without impairing the fun of the game by this jackpot probability reduction restarting means. .

  By the way, there are various possible establishments of the predetermined third game condition that is to be resumed by canceling the execution of the stopped big hit probability reducing means. That is, in the gaming machine according to claim 12, in the gaming machine according to claim 11, when the predetermined variation pattern or character is displayed in the slot game, the predetermined third gaming condition is satisfied.

  In other words, in the present invention, when a predetermined variation pattern, for example, a variation pattern related to reach or a predetermined character is displayed in the slot game when the execution of the big hit probability reducing means is stopped, this stopped big hit is displayed. The execution of the probability reduction means is canceled and the execution of the jackpot probability reduction means is started again. Note that when the predetermined background image or the like is displayed instead of or in addition to the fluctuation pattern or character, the stoppage of the big hit probability reducing means may be canceled.

  In addition, as a specific configuration of the present invention, for example, the following may be used. That is, the control means comprises a main control means (for example, a main board) and a display control means (for example, an image control board), and the display control means displays a variation pattern related to reach, a predetermined character, a predetermined background image, or the like. When data (for example, random numbers) is acquired, a signal based on the acquired data is transmitted from the display control means to the main control means, and the main control means stops the jackpot probability reduction means based on the received signals. May be canceled.

  According to the invention of claim 12 having such a configuration, in addition to the effect of the invention of claim 11, the player is interested not only in the symbols that are confirmed and displayed, but also during the change of the symbols and in the characters. As a result, the game taste is improved.

  Here, when reducing the increasing jackpot probability, it becomes a problem how much it is reduced. In such a case, it is better to do as follows. That is, the gaming machine according to claim 13 is the gaming machine according to any one of claims 1 to 12, wherein the big hit probability reducing means reduces the rising big hit probability before the rising. To reduce the jackpot probability. In this case, the jackpot probability lower than at least the jackpot probability before rising (the so-called jackpot probability in the normal gaming state) is not obtained. Therefore, according to the invention of claim 13 having such a configuration, the claim 1 In addition to the effects of any of the thirteenth to twelfth aspects, the player can enjoy the game with peace of mind.

  In the invention of claim 13, the rising jackpot probability is reduced to the jackpot probability before rising, but this is a probability close to the jackpot probability before rising (for example, a range of plus or minus 10%). You may make it fall in the inside. Alternatively, it may be reduced to a plurality of different jackpot probabilities with a probability not lower than the jackpot probability before rising.

  A gaming machine according to a fourteenth aspect is the gaming machine according to any one of the first to thirteenth aspects, further comprising an effect image display means, wherein the effect image display means is a jackpot probability reduction means or / and A predetermined effect image related to execution or stop of the big hit probability lowering stop means is displayed on the image display device. This effect image is obtained by making full use of various characters and various background images together with, for example, characters, voice, light, etc., and the display of the effect display depends on the character type, movement, appearance status, type or color of the background image, etc. The intention is appealing to the player. Therefore, in the invention of claim 14 having such a configuration, in addition to the effects of any one of claims 1 to 13, the player knows various information that is extremely important for winning the jackpot by the image display device. As a result, it is possible to appropriately determine the current gaming state and predict the future development of the game, and further improve the interest of the game.

  Here, there are various types and display timings of effect images. For example, when the big hit probability lowering means is stopped or when the big hit probability lowering stop means is restarted, it is displayed continuously or in pieces during the slot game display period. You may make it do. Alternatively, it may be displayed immediately after the end of the slot game, or may be displayed across a plurality of slot games. Furthermore, it may be as follows. That is, the gaming machine according to claim 15 is the gaming machine according to claim 14, wherein the effect image display means displays a predetermined number of slot games without increasing the jackpot probability after the jackpot probability has increased. When the game is performed, the effect image indicating that the jackpot probability is still increasing is displayed. In the gaming machine according to claim 16, the number of times of the slot game is increased in the gaming machine according to claim 15. It is set based on the jackpot probability, and is set larger than at least the reciprocal of the increased jackpot probability.

  That is, in the invention of claim 15, when the jackpot probability is increased and then the increased jackpot probability is continued without decreasing, a predetermined number of slot games, for example, a slot game after the jackpot probability is increased 100 times. Each time the effect image display means has a jackpot probability with an increased jackpot probability, the effect image display means displays in the effect image that it is likely to be a big hit than usual. Therefore, according to the invention of claim 15, in addition to the effect of the invention of claim 14, the increased jackpot probability is lowered even if a predetermined number of slot games, that is, a certain period of time elapses after the jackpot probability is increased. If not, since the effect image indicates that the jackpot probability is still rising, the player can face the game with peace of mind.

  Further, as in the invention of claim 16, the number of slot games for displaying the effect image is set based on the increased jackpot probability, and at least from the inverse of the increased jackpot probability. Is set to be larger. For example, when the increased jackpot probability is 1/63, the number of slot games for displaying the effect image is set to be greater than the reciprocal of 1/63, that is, 63. Times, 200 times, 300 times (multiple of 100). Here, the 1/63 jackpot probability means that if 63 slot games are played on average, it will be a big hit once. Therefore, after the jackpot probability has increased, 100 slot games will be played. When this happens, the player is already in a period of suspicion that the jackpot probability has been reduced to the normal probability. The effect image is displayed to the effect that it is likely to be a big hit than usual.

  According to the invention of claim 16 having such a configuration, in addition to the effect of the invention of claim 15, when a considerable amount of time that would otherwise be a big hit has elapsed since the end of the big hit game. Since the effect image shows that the jackpot probability is still rising, the player will continue to play with great expectations without giving up the game, and as a result, the interest of the game will increase In addition, the operating rate of the gaming machine is improved.

  In addition to the invention of claim 16, the number of slot games for displaying the effect image may be set as follows. That is, there is a correlation between the number of slot games and the lottery probability of a lottery that reduces the jackpot probability, and at least both of them have a value close to or smaller than the reciprocal of the lottery probability. Set the relationship. For example, when the lottery probability for reducing the big hit probability is 1/100, this reciprocal is 100. Therefore, the number of times of the slot game is a multiple of 100 as described above, for example. In this case, the relationship between the two is that the number of slot games and the reciprocal of the lottery probability are the same value, that is, if the number of times of the slot game is considerably larger than the reciprocal of the lottery probability. The fact that the effect image of the corner that indicates that the probability is a jackpot probability with an increased probability may not be executed at all, and the effect display that informs the player of advantageous information is not executed once. This is because the design of the gaming machine is not preferable. However, because the lottery probability of the lottery that reduces the jackpot probability cannot be set to a very low probability due to the design of the gaming machine, the correlation between the number of slot games and the lottery probability is therefore the number of slot games. Is preferably set to a value close to the reciprocal of the lottery probability or a value smaller than that value.

  The gaming machine according to claim 17 is the gaming machine according to any one of claims 14 to 16, wherein the control means comprises main control means and display control means, and the main control means and display control. Communication with the means is only in one direction from the main control means to the display control means. The effect image display means displays the effect image based on the display command signal when the display control means receives a predetermined display command signal from the main control means, that is, a command signal for instructing display of the predetermined effect image. Display on the device.

  Therefore, according to the invention of claim 17 having such a configuration, in addition to the effects of any one of claims 14 to 16, the entire gaming machine is provided by one-way communication from the main control means to the display control means. The number of input to the main control means that controls the main control of the system can be reduced to eliminate illegal signal input as much as possible, the security of the gaming machine is improved, and display control of a predetermined display command signal from the main control means at a desired timing The effect image can be displayed on the image display device at a desired timing simply by transmitting to the means.

  Further, in the gaming machine according to claim 18, in the gaming machine according to claim 17, a plurality of types of effect images are provided, and the display control means is based on the timing of receiving the display command signal from the main control means. Any one of the plurality of types of effect images is selected by lottery by a predetermined random number process.

  Here, the predetermined random number processing is, for example, creating a loop counter that generates random numbers of 0 to 999 as random numbers for determining effect images in a storage area such as a microcomputer, and assigning each of a plurality of types of effect images to 0 to A random number is set in correspondence with a random number of 999, and one random number is selected from 0 to 999 based on a predetermined timing (in the present invention, the timing at which the display control unit receives a display command signal from the main control unit). For example, in this case, each of a plurality of types of effect images is set to a predetermined probability. In addition, uniformity and irregularity are ensured with respect to the actual selection order.

  When one effect image is selected from among a plurality of types of effect images, the effect image display means displays the selected effect image on the image display device. Therefore, according to the invention of claim 18 having such a configuration, in addition to the effect of the invention of claim 17, one of the plurality of types of effect images is maintained while maintaining uniformity and irregularity. Since it will be displayed on the screen, the game taste is improved. Furthermore, since the display control means, rather than the main control means, selects one of a plurality of types of effect images at random by a predetermined random number process, it is possible to reduce the load on the main control means which is burdensome. As a result, a stable control circuit can be realized and the cost of the main control means can be reduced.

Even if the power supply of the gaming machine 1 is suddenly cut off due to surge current entering the gaming machine 1 or the like, the game is stored in the RAM 104 of the main control circuit 44, the RAM 141 of the display control circuit 111, and the VRAM 144. Since all the data is preserved, when the power of the gaming machine 1 is restored, the game can be resumed from the previous gaming state, and the game arcade can provide a fair game to the player, while the player, for example, Even if the power is cut off in an advantageous gaming state, it is possible to continue the advantageous gaming state after the power is restored, so there is an unexpected disadvantage It can be avoided. In addition to the RAM 104 of the main control circuit 44 and the RAM 141 and VRAM 144 of the display control circuit 111, this backup function is also 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 as described above. May be. The RAM 141 described above may not be built in the CPU 140 and may be external to the CPU 140.

  Further, the control signal (strobe signal, command signal, etc.) is communicated in one direction 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 input 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. Note that the one-way communication from the CPU 102 of the main control circuit 44 is not limited to the display control circuit 111 as shown in FIG. 3 but also to other control circuits such as the payout control circuit 40 for paying out the prize balls. To do.

  When the substrate on which the main control circuit 44, the payout control circuit 40, etc. are stored is stored in the substrate BOX, a so-called caulking structure that is sealed by a predetermined means so as to leave a trace of opening the substrate BOX remains. It is desirable to adopt. As a result, fraud to the main control circuit 44 and the payout control circuit 40 can be further eliminated. Further, the normal symbol display device 18 connected to the display control circuit 111 may be directly connected to the output circuit 110 of the main control circuit 44, or the lamp control circuit directly connected to the output circuit 110 of the main control circuit 44. 37 and the audio control circuit 38 may be connected to the display control circuit 111 or the payout control circuit 40. Further, 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.

Starting from 0 when the power is turned on, it is incremented (added by 1) every reset interrupt (4 msec). However, when this random number counter C8 becomes 52, it is rewritten to 0.

  Does the fall lottery stop determination counter C9 (random numbers 9, 0 to 49) stop the lottery executed by the probability variation fall determination counter C10 described below to drop the rising big hit probability to the normal big hit probability? Random number counter for lottery (details will be described later, probability of stopping in the normal case 1/50), starting from 0 when the power is turned on, and incrementing (adding 1) every reset interrupt (4 msec) Is done. However, when this random number counter C9 becomes 50, it is rewritten to 0.

  The probability variation fall determination counter C10 (random numbers 10, 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, in each slot game, a random number counter (which will be described in detail later, the probability of falling 1/100 in the normal state) that draws whether or not this rising jackpot probability falls to the normal jackpot probability. Thus, it starts from 0 when the power is turned on and is incremented (added by 1) every reset interrupt (4 msec). However, when this random number counter C10 becomes 200, it is rewritten to 0.

Is done. However, when the random number counter C13 becomes 9, it is rewritten to 0.

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

  FIG. 8 is a flowchart showing the operation gate passing process. When this operation gate passage process is started, the CPU 102 determines whether or not the game ball that has passed the normal symbol operation gate 19 is detected (operation signal input to the operation gate detection sensor 121) (step S452). If a game ball is not detected (NO in step S452), the operation gate passing process is terminated, and the process proceeds to the normal symbol game process (FIG. 10) in 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 A is less than 5. The counter A 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 121 is a normal symbol operation gate 19. 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 A is a value of 5 or more, the CPU 102 ends the operation gate passing process. On the other hand, if YES in the process of step S454, that is, if the counter A has a value of 0 to 4, the process proceeds to the process of step S456, and the CPU 102 increments the value of the counter A (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 C12 and C13, and stores them in the acquired numerical value storage areas of the RAM 104, respectively. When the random number acquisition process in step S458 ends, the CPU 102 proceeds to the hold LED lighting control process in step S464.

  FIG. 9 is a flowchart showing the hold LED lighting control process (step S464). When the hold LED lighting control process is executed, the CPU 102 first determines in the process of step S466 whether or not the value of the counter A is 2 or more (NO in step S466), that is, When the value of the counter A is 0 or 1, the hold LED lighting control process is terminated. On the other hand, if YES in the process of step S466, that is, if the value of the counter A 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 lighting control process is terminated.

  FIG. 10 is a flowchart showing the normal symbol game process (step S500). When the normal symbol game process is executed, the CPU 102 first determines whether or not the value of the counter A is 1 or more in the process of step S501, and if not (1 in step S501), that is, the counter When the value of A is 0, the normal symbol game process is terminated and the process proceeds to the process of step S40 of the main game process (FIG. 5). On the other hand, when the value of the counter A 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 F4.

  The main control circuit 44 is set with a hit flag F4 (see FIG. 22 described later), and the hit flag F4 is set to 0 when the power is turned on. Then, in the random number acquisition process in step S458 described above, when the acquired numerical value of the hit determination counter C12 (random numbers 12, 0 to 30) is 0 to 9, the CPU 102 sets 1 to the hit flag F4. Note that if the acquired numerical value of the hit determination counter C12 is not 0 to 9, that is, 10 to 30, the hit flag F4 remains 0. Accordingly, 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 F4 in step S502, the CPU 102 proceeds to a normal symbol determination process in step S503.

  FIG. 11 is a diagram illustrating the relationship between the random number value of the off symbol determination counter C13 (0 to 8) and the normal symbol (one-digit normal symbol displayed on the normal symbol display device 18 constituted by 7-segment LEDs). FIG. 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 18. If 1 is set in the winning flag F4 (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 F4, an error symbol corresponding to the acquired numerical value of the error symbol determination counter C13 (0 to 8) shown in FIG. 11 (for example, “2” if C13 = 2). 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 of step S506, in order to display the normal symbol determined in the normal symbol determination process of step S503 described above on the normal symbol display device 18 after the variable display, the CPU 102 Output transmission data.

  That is, this transmission data is output from the main control circuit 44 to the display control circuit 111, and from the start of fluctuation of the single-digit normal symbol displayed on the normal symbol display device 18 composed of 7-segment LEDs. It is defined that two commands are transmitted as display control commands before the final display. As for these two commands, the normal symbol designation command for designating the normal symbol variation start and the normal symbol stop symbol is first transmitted, and then the normal symbol stop designation command for designating the normal symbol stop is designated by the above normal symbol designation. It is configured to be transmitted when the time t has elapsed since the command was transmitted. Therefore, this time t is the normal symbol change time, that is, the time from when the normal symbol starts changing to the normal symbol display device 18 until it stops. The normal symbol variation time t is set to 30 seconds.

  Ten types of normal symbol designation commands are prepared corresponding to the normal symbols (0 to 9), and a stop symbol (determined symbol) is designated. One type of the normal symbol stop designation command is prepared and designates the stop timing of the normal symbol. The normal symbol designation command and the normal symbol stop designation command described above are transmitted from the main control circuit 44 and received by the display control circuit 111, so that the normal symbol starts to fluctuate and is displayed after being stopped. The fluctuation display of the times is normally displayed by the symbol display device 18.

  When the normal symbol variation display process of step S506 is completed, the CPU 102 proceeds to the process of step S508, and determines whether or not the above-described normal symbol variation time t is up (t = 0). If NO in step S508, that is, if it is determined that the normal symbol variation time t has not timed up, the CPU 102 ends the normal symbol control process (step S504) and performs the process in step S512. Migrate to 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.

  When the process proceeds to step S510, the CPU 102 executes a process of confirming and displaying the normal symbol determined in the normal symbol determination process of step S503 on the normal symbol display device 18 as described above. Then, when the process of step S510 is completed, the CPU 102 ends the normal symbol control process and proceeds to the process of step S512.

  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 18, and if it 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, if it is determined in step S512 that the normal symbol is confirmed and displayed on the normal symbol display device 18 (YES in step S512), the CPU 102 proceeds to the process in step S514. It is determined whether or not the value of flag F4 is 1, and if it is 1 (YES in step S514), the process proceeds to step S516, and the start winning opening releasing process is executed.

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

  This counter G counts the main control circuit 44 in order to count the number of game balls won in the start winning opening 11 until the opened winning opening 11 is closed after the start winning opening 11 elapses. Is counted up when the count switch 123 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 G is determined to be less than 6, the start winning opening releasing 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 expired or when the value of the counter G is determined to be 6 or more, In step S524, the CPU 102 controls the solenoid 107 to close the blades of the start winning port 11. Then, the process proceeds to step S525, and the CPU 102 sets the value of the counter G to 0, proceeds to the process in step S526, sets the value of the winning flag F4 to 0, and this start winning opening releasing process. (Step S516) is ended, 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 F4 is 0, that is, whether or not all predetermined start winning opening opening processing (step S516) is completed, and the value of the winning flag F4 is determined. Is not 0 (NO in step S528), that is, in the case of 1, it is determined that all the predetermined start winning opening opening processing has not ended, and this normal symbol game processing (step S500) is ended. On the other hand, when the value of winning flag F4 is 0 (YES in step S528), CPU 102 determines that all the predetermined start winning port opening processes have been completed, and proceeds to the process of step S530. On the other hand, if the value of the hit flag F4 is not 1 in the process of step S514 (NO in step S514), that is, if the value of the hit flag F4 is 0, the CPU 102 proceeds to the process of step S530. . After shifting to the process of step S530, the CPU 102 decrements (decrements 1) the value of the counter A incremented (added by 1) in the process of step S456 (FIG. 8) described above, and shifts to the process of step S532. The hold LED extinguishing control process is executed.

  FIG. 14 is a flowchart showing the hold LED extinguishing control process (step S532). When the hold LED extinguishing control process is executed, the CPU 102 first determines whether or not the value of the counter A is 1 or more in the process of step S534. If the value of the counter A is not 1 or more (in step S534) NO), that is, if the value of the counter A is 0, the hold LED extinguishing control process is terminated, the normal symbol game process (step S500) is terminated, and the process of step S40 of the main game process (FIG. 5) Migrate to On the other hand, if YES in step S534, that is, if the value of the counter A 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. The corresponding one is driven to turn off the lamp control circuit 37, and the hold LED turn-off control process is finished.

  Returning to FIG. 5, when the normal game process (step S30) is completed, the CPU 102 proceeds to step S40 and executes the special game process. FIG. 15 is a flowchart showing the special game process. The special game process includes a start winning opening winning process in step S300 and a special symbol game process in step S317. First, the starting winning opening winning process in step S300 will be described.

  FIG. 16 is a flowchart showing the start winning opening winning process. When the start winning award winning process is started, the CPU 102 determines whether or not a game ball won in the start winning award 11 is detected (start signal input from the start winning detection sensor 116) (step S302). If no game ball has been detected (NO in step S302), the start winning opening winning process is terminated and the process proceeds to a special game process in step S317. On the other hand, when a game ball is detected (YES in step S302), the process proceeds to step S303 to determine whether the value of counter B is less than 5. This counter B is the same as the counter A described above, and is a counter set in the main control circuit 44 to store the number of reserved memories (the number of held balls) of the hold LED 25, and the start winning detection sensor 116 is started. When a game ball that has won a prize opening 11 is detected, the game ball changes from a minimum value 0 to a maximum value 5, and is initialized and a minimum value 0 is set when the power is turned on.

  If NO in step S303, that is, if the counter B has a value of 5 or more, the start winning opening winning process is terminated. On the other hand, if YES in the process of step S303, that is, if the counter B has a value of 0 to 4, the process proceeds to the process of step S304, where the CPU 102 sets 1 to the probability change flag F7 (see FIG. 22 described later). It is determined whether or not the jackpot probability is high and the probability is high. If YES in the process of step S304, that is, if the big hit probability has increased to a high probability, the process proceeds to step S305, and the CPU 102 increments (adds 1) the value of the counter K. This counter K is set in the main control circuit 44 in order to store the number of game balls (the number of times the slot game is executed, hereinafter also referred to as the probability variation number) won in the start winning slot 11 while the probability of winning a big hit is high. It is a counter that is initialized when the power is turned on and is set to 0. Every time a slot game is executed by detecting a game ball that has won a winning winning opening 11 with a high probability of jackpot The value is incremented (added by 1).

  If NO in step S304, that is, if the big hit probability is not high, or when the process in step S305 is completed, the process proceeds to step S308, and the CPU 102 determines the value of the counter B based on the start signal described above. Is incremented (added by 1), the process proceeds to step S310, and a random number acquisition process is executed. When the CPU 102 proceeds to the random number acquisition process in step S310, the CPU 102 acquires the current values of the counters C1, C5, C6, C8, C9, C10, and C11 out of the counters C1 to C13 described above, and stores the acquired numerical values in the RAM 104. Store each in an area. When the random number acquisition process in step S310 ends, the CPU 102 proceeds to step S312 and executes the hold LED lighting control process.

  FIG. 17 is a flowchart showing the hold LED lighting control process (step S312). When the hold LED lighting control process is executed, the CPU 102 first determines whether or not the value of the counter B is 2 or more in the process of step S314. If the value is not 2 or more (NO in step S314), that is, When the value of the counter B is 0 or 1, the hold LED lighting control process is terminated and the special symbol game process of step S317 is executed. On the other hand, if YES in the process of step S314, that is, if the value of the counter B is 2 or more, the process proceeds to step S316, 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 lighting control process (step S312) is ended.

  FIG. 18 is a flowchart showing the special symbol game process (step S317). When this special symbol game process is executed, the CPU 102 first determines whether or not the value of the counter B is 1 or more in the process of step S318. If the value of the counter B is not 1 or more (in step S318) NO), that is, if the value of the counter B is 0, the special symbol game process is terminated and the process proceeds to step S50 of the main game process (FIG. 5). On the other hand, when the value of counter B is 1 or more in the process of step S318 (YES in step S318), the process proceeds to the high-probability suggesting effect process of step S319.

  FIG. 19 is a flowchart showing the high probability suggesting effect process (step S319). When the high probability suggesting effect process is executed, the CPU 102 first determines whether or not the value of the counter K has reached a predetermined value in the process of step S320. Here, the predetermined value of the counter K is set to a multiple of 100 (100, 200, 300...). If NO in step S320, that is, if the value of the counter K is not a predetermined value, the high-probability suggesting effect process is terminated, and the process proceeds to the falling lottery stop process in step S322. On the other hand, if YES in the process of step S320, that is, if the value of the counter K is a predetermined value, the process proceeds to step S321, and the CPU 102 outputs a high-probability suggesting effect command to the display control circuit 111. Then, effect display is performed on the image display unit 30 of the special symbol display device 6 to suggest that the big hit probability is high. This high probability suggesting effect display will be described in detail later.

  Thus, the high-probability suggestion display is displayed over a plurality of slot games, and the number of continuations thereof is as shown in FIG. 20, and the effect acquired in the random number acquisition process in step S310 described above. It is determined based on the value of the continuation number determination counter C11 (random numbers 11, 0 to 4). FIG. 20 is an explanatory diagram showing the relationship between the effect continuation number determination counter C11 and the effect continuation number of the high-probability suggestion effect display.

  That is, in the process of high-probability suggestion effect command output executed in step S321, the CPU 102 instructs the display control circuit 111 to instruct high-probability suggestion effect display and the signal for instructing the number of times of high-probability suggestion effect display effect continuation. (Direction continuation number designation command) is also output. For example, as shown in FIG. 20, when the value of the counter C11 for determining the number of production continuations is 2, the number of production continuations of the high-probability suggestion production display is five, including the current slot game and five times thereafter. This means that the high-probability suggestion display is continuously displayed over the slot game. However, as will be described later, even if the number of continuations of the high-probability suggestion effect display is less than five, if the big hit probability falls from the high probability, the high-probability suggestion effect display is terminated at that time. When the process in step S321 is completed, the high-probability suggesting effect process is terminated, and the process proceeds to the falling lottery stop process in step S322.

  In other words, the high-probability suggestion effect process in step S319 is executed each time the number of times of the slot game (the number of chances of variation) based on the game ball won in the start winning opening 11 while the jackpot probability is high is a multiple of 100. It has come to be. Although the jackpot probability will be described later, it is 1/63 when rising to a high probability, that is, this is a big hit once if 63 slot games are played while the jackpot probability is high on average. Means. For this reason, if a slot game is played 100 times after the jackpot probability has become high, the player is suspicious that the jackpot probability has already fallen to the normal probability (1/315). Therefore, if a high-probability suggestion display is performed regularly at such a time and thereafter by the high-probability suggestion effect process, the player has not yet fallen from the high probability of the big hit probability. Since it can be predicted that the game is maintained and the game can be played with great expectation, that is, an appropriate judgment can be made to continue the game, so that the game taste is improved. In other words, the probability variation number is set based on the jackpot probability in the high probability, and at least the probability variation number (100) is preferably larger than the denominator (63) of the jackpot probability in the high probability.

  FIG. 21 is a flowchart showing the falling lottery stop process (step S322). When the falling lottery stop process is executed, the CPU 102 first determines whether or not 1 is set in the probability variation flag F7 in the process of step S323. 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 six main flags in total, and each of these flags is set to 0 when the power is turned on. F1, F2 and F3 are a big hit flag, a reach flag F2 and a reach mode flag, and these flags are a big hit determination counter C1, a reach determination counter C5, a reach symbol mode determination counter in the process of step S345 described later. Based on the value of 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. F4 is a hit flag, and this flag is set to 1 based on the value of the hit determination counter C12 in the process of step S502, as described above.

  F6 is a falling lottery flag, and this flag is determined to stop the lottery in which the big hit probability falls from the high probability to the normal probability based on the value of the falling lottery stop determination counter C9 in the process of step S329 described later. When set, 1 is set. F7 is a probability variation flag, and this flag is set to 1 based on the fact that the jackpot probability has increased in the processing of step S428 described later. In other words, when F6 is set to 1, the lottery to drop the big hit probability from the high probability to the normal probability is stopped, and when F7 is set to 1, the big hit probability becomes high probability. It shows that there is.

  Returning to FIG. 21, it is determined whether or not the probability variation flag F7 is set to 1 in the process of step S323, that is, whether or not the big hit probability has increased, and NO or the big hit is determined in the process of step S323. If the probability has not risen and is a normal probability, the falling lottery stop processing is terminated, and the routine proceeds to the probability variation falling processing in step S331. On the other hand, if YES in the process of step S323, that is, if the big hit probability is high, the process proceeds to step S324, and the CPU 102 determines whether or not 0 is set in the falling lottery flag F6. It is determined whether or not the lottery for dropping the big hit probability from the high probability is stopped. If the lottery for dropping the big hit probability from the high probability is stopped in the process of step S324, this lottery Terminate the stop process. On the other hand, if YES in the process of step S324, that is, if a lottery that drops the jackpot probability from a high probability is executed, the process proceeds to step S325, and the CPU 102 determines whether the value of the counter B is 4 or more. If the value of counter B is 4 or more, that is, if the number of reserved balls is 3 or more (YES in step S325), the process proceeds to step S326, and the random number update in step S20 described above is performed. The contents of the falling lottery stop determination counter C9 (random numbers 9, 0 to 49) updated in the process are changed.

  Here, as shown in FIG. 23, the random number 9 created in the process of step S20 in normal times is a specific big symbol (“1, 1, 1”, “3, 3, 3”, “5, 5, 5 ”,“ 7, 7, 7 ”,“ 9, 9, 9 ”,“ 11, 11, 11 ”,“ 13, 13, 13 ”), the falling lottery stop probability is 1/50. If YES in the process of S325, this falling lottery stop probability is increased with a probability change to 1/25 (at the time of probability change). This is, among the above-mentioned falling lottery stop determination counter C9 composed of 0 to 49, the random value for stopping the lottery to drop the big hit probability from the high probability to the normal probability is 19 at normal time. Is changed to 19 and 39 at the time of probability change. FIG. 23 is an explanatory diagram showing the relationship between a specific big symbol, a fall probability, and a fall lottery stop probability.

  Then, when the process of step S326 is completed, or when the process of step S325 is NO, that is, when the number of reserved balls is two or less, the CPU 102 proceeds to the process of step S327, and the random number of step S310 described above. Based on the value of the falling lottery stop determination counter C9 (random numbers 9, 0 to 49) acquired in the acquisition process, it is determined whether or not to stop the lottery to drop the big hit probability from a high probability. Here, as described above, the falling lottery stop probability used for the determination in step S327 is 1/25 when YES in the process of step S325 (when there are three or more holding balls), In the case of NO in the process of step S325 (when there are only two or less reserved balls), 1/50 is applied.

  If NO in the process of step S327, that is, if it is determined not to stop the lottery in which the jackpot probability falls from a high probability in the current slot game, the CPU 102 ends the falling lottery stop process. On the other hand, if it is determined YES in the process of step S327, the CPU 102 proceeds to the process of step S328, and the lottery to drop the big hit probability from the high probability in this slot game, and the high hit probability is a high probability. The lottery to stop the lottery to fall from is stopped. Then, the process shifts to the process of step S329, and the CPU 102 sets 1 to the fall lottery flag F6, shifts to the process of step S330, outputs a fall lottery stop effect command to the display control circuit 111, and the special symbol display device. The image display unit 30 of 6 displays directly or indirectly the fact that the lottery for dropping the big hit probability from the high probability and the lottery for stopping the lottery are stopped. This falling lottery stop effect display will be described in detail later.

  Therefore, when the lottery lottery stop processing increases the jackpot probability to a high probability, and there are three or more holding balls when the lottery is executed to drop the jackpot probability from the high probability, the jackpot probability is increased. Since the probability of stopping the lottery that falls from the probability increases, the possibility that it will be a big hit again increases, and the player is able to maintain the big hit probability without falling from the high probability by the fall lottery stop effect display and the big hit Since it is possible to predict that the lottery for dropping the probability from the high probability and the lottery for stopping the lottery are stopped, the gameability of the gaming machine 1 is improved. Further, the player intermittently uses a so-called “stopping ball” (a ball hitting device 43 that discharges a game ball to the game area 5 in order to prevent the holding ball from overflowing beyond four in order to increase the falling lottery stop probability. The operation rate of the gaming machine 1 is improved. When the process of step S330 is completed, the CPU 102 ends the falling lottery stop process and proceeds to the probability change falling process of step S331.

  FIG. 24 is a flowchart showing the probability change fall process (step S331). When this probability variation fall process is executed, the CPU 102 executes the processes of step S332, step S333, and step S334. Note that these processes are the same as the processes in step S323, step S324, and step S325 of the above-described falling lottery stop process (FIG. 21), and thus description thereof is omitted here. If YES in the process of step S334, that is, if the jackpot probability is high and lottery is executed to drop the jackpot probability from the high probability, if the number of reserved balls is three or more, step Shifting to the process of S335, the contents of the probability variation fall determination counter C10 (random numbers 10, 0 to 199) updated in the random number update process of step S20 described above are changed.

  As shown in FIG. 23, the random number 9 created in the process of step S20 is normally a specific big symbol (“1, 1, 1”, “3, 3, 3”, “5, 5, 5” described later). ”“ 7, 7, 7 ”,“ 9, 9, 9 ”,“ 11, 11, 11 ”,“ 13, 13, 13 ”), the fall probability is 1/100, but the process of step S335 If the answer is YES, the fall probability is decreased with probability fluctuation and is reduced to 1/200 (at the time of probability change). This is because of the probability variation fall determination counter C10 configured from 0 to 199 described above, a random number value that falls from a high probability to a normal probability is assumed to be a random probability value. Sometimes done by changing to 55 only.

  Here, the reason why the fall probability set at the normal time is set to 1/100 is as follows. That is, in the above-described high probability suggestion effect process (step S319), the high probability suggestion effect display is executed every time the number of times of the slot game (the number of probability changes) performed during the high probability of the big hit probability is a multiple of 100. Therefore, it is natural that the high-probability suggestion display is first performed when the probability variation number is the 100th. Therefore, if the fall probability is set to a probability higher than 1/100, the high-probability suggesting effect display may not be executed at all, and the effect display for informing information advantageous to the player is executed once. This is because the design of the gaming machine 1 is not preferable. However, because of the design of the gaming machine 1, the fall probability cannot be set to a very low probability, and here, the probability variation number of 100 is matched with the denominator of the fall probability. That is, there is a correlation between the fall probability and the probability variation number, and at least the probability variation number (100) is desirably a value close to or smaller than the denominator (100) of the fall probability.

  When the process of step S335 is completed, the CPU 102 proceeds to the process of step S336, outputs a fall probability reduction effect command to the display control circuit 111, and outputs the above-described step S326 to the image display unit 30 of the special symbol display device 6. Corresponding to the process (change of the falling lottery stop determination counter C9), the probability of the fallen lottery stop is increased, and the fall probability is decreased corresponding to the process of step S336 (changing the probability variation fall determination counter C10). The effect is displayed directly or indirectly. This drop probability reduction effect display will be described in detail later.

  Therefore, if the lottery is executed when the lottery is executed to increase the big hit probability from the high probability by the processing of step S332 to step S336 and the big hit probability falls from the high probability, Since the probability of falling from a high probability decreases, the possibility of becoming a big hit again increases, and the player has increased the probability of falling lottery stop by the fall probability reduction effect display and the falling probability has decreased Therefore, the gaming property of the gaming machine 1 is improved. Furthermore, since the player does not perform the above-described stopping to reduce the fall probability, the operating rate of the gaming machine 1 is improved.

  Then, when the process of step S336 is completed, or when the process of step S334 is NO, that is, when the number of reserved balls is two or less, the CPU 102 proceeds to the process of step S340 and the random number of step S310 described above. It is determined whether or not the jackpot probability falls from a high probability based on the value of the probability variation fall determination counter C9 (random number 9, 0 to 199) acquired in the acquisition process. Here, as described above, the drop probability used for the determination in step S340 is 1/200 when YES in the process of step S334 (when there are three or more holding balls), and step S334 is applied. In the case of NO in this processing (in the case where there are only two or less reserved balls), 1/100 is applied.

  If NO in step S340, that is, if it is determined that the jackpot probability is not to be dropped from a high probability in the current slot game, the CPU 102 ends the probability variation falling process. On the other hand, if YES in the process of step S340, that is, if it is determined that the big hit probability falls from the high probability in the current slot game, the CPU 102 proceeds to the process of step S341, and the random number of step S20 described above. The contents of the jackpot determination counter C1 (random numbers 1, 0 to 314) updated in the update process are changed, and the jackpot probability increased in the process of step S426 described later is reduced. This is because when the probability changes, the random number 1 created in the process of step S20 has a lottery probability that the combination of special symbols is a big win, but it is 5/315. Is reduced 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 and 222 among the big hit random numbers composed of 0 to 350 described above.

  When the process of step S341 ends, the CPU 102 proceeds to the process of step S342, sets the probability variation flag F7 to 0, proceeds to the process of step S343, and currently displays the image display unit of the special symbol display device 6. At 30, it is determined whether or not the high-probability suggestion effect display indicating that the big hit probability is high is performed based on the above-described high-probability suggestion effect process (step S319).

  If NO in the process of step S343, that is, if the high-probability suggesting effect display is not currently being performed on the image display unit 30 of the special symbol display device 6, this probability variation falling process is terminated. On the other hand, if YES in the process of step S343, that is, if a high-probability suggestion display is currently being performed, the process proceeds to step S344, and the CPU 102 outputs an abort effect command to the display control circuit 111. Then, on the image display unit 30 of the special symbol display device 6, the high probability suggestion effect display is discontinued, and an effect display that suggests that the jackpot probability has fallen from the high probability in this slot game is performed. This discontinuation effect display will be described in detail later.

  In other words, the high-probability suggestion display is an effect display that suggests to the player over a plurality of slot games when the jackpot probability has not fallen from the high probability. If the big hit probability falls from the high probability unfortunately, it switches from the high probability suggestion effect display to the censoring effect display, and this clash effect display causes the player to drop the big hit probability from the high probability. It suggests that. Therefore, the processing of step S343 and step S344 can always provide an appropriate effect display, and the player can predict that the big hit probability has fallen from the high probability by the discontinuation effect display. The playability of the machine 1 is improved. When the process of step S344 is completed, the CPU 102 ends the probability change fall process and proceeds to the process of step S345.

  Returning to FIG. 18, when the process proceeds to step S <b> 345, the CPU 102 sets values for the big hit flag F <b> 1, the reach flag F <b> 2, and the reach mode flag F <b> 3. In the random number acquisition process in step S310 described above, when the acquired numerical value of the big hit determination counter C1 (random numbers 1, 0 to 314) is normal (F7 = 0), the big hit probability is high (F7 = 1). In the case of 7, 33, 77, 111, 222, the big hit flag F1 is set to 1. Note that if the acquired value of the big hit determination counter C1 is other than that, the big hit flag F1 remains zero. Therefore, the big hit probability at normal time is 1/315, the probability of loss is 314/315, the big hit probability at high probability is 5/315, and the 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 F2. It should be noted that the reach flag F2 remains 0 if the acquired value of the reach determination counter C5 is not 3, that is, 0-2 and 4-11. Therefore, in this case, the probability of detachment of reach is 1/12, and the probability of detachment of non-reach is 11/12.

  Further, when the acquired numerical value of the reach symbol mode determination counter C6 (random number 6, 0 to 62) is 0 to 19, 1 is set to the reach mode flag F3. In addition, when the acquisition numerical value of the reach symbol mode determination counter C6 is 20 to 62, the reach mode flag F3 remains 0. Accordingly, in this case, the probability of reach divergence in which the middle symbol display unit 9 becomes plus / minus one symbol is 20/63, and the probability of reach detachment in which the middle symbol display unit 9 is other than plus / minus one symbol is 43/63. CPU102 transfers to the special symbol determination process of step S346, after complete | finishing the process of step S345.

  FIG. 25 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 F1 is 0 in step S347. If the value of the big hit flag F1 is not 0 (NO in step S347), that is, if the value of the big hit flag F1 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.

  26 and 27, 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, the case where each special symbol displayed on the right symbol display unit 10 is created will be described. 26 and 27 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. 26 (A), (B), (C), and FIG. 27 (A), a case where an outlier (including a reach out) is created as a special symbol combination will be described.

  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 As shown in FIGS. 26 (A), (B), and (C), special symbols 1 to 14 correspond to random numbers 0 to 13, and are counted up as described in the random number update process in step S20. However, since the process of continuing to update during the remaining time of the main game process is performed by the random number update process of step S60 shown in FIG. 5 described in detail later, each random value is a random value every 4 msec. As a result, each special symbol corresponding to the random value is also created as random data every 4 msec.

  As shown in FIG. 27 (A), 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 4 msec is stored in the RAM 104. Is stored while being rewritten in a predetermined symbol storage buffer created in the storage area. Here, as the special symbol combination, when the data of the out-of-reach data in which the middle symbol display unit 9 becomes plus / minus one symbol is created, the reach symbol storing buffer of plus / minus one symbol 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 reach which is not 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 that does not become reach, and when the jackpot symbol data shown in FIG. 26 (D) is created as a special symbol combination. , Not to be remembered. In FIG. 27 (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 special symbols that are not reachable, and “5, 5, 1” is shown as a combination of special symbols that are not reachable.

  Next, the case where a big hit symbol is created as a combination of special symbols will be described with reference to FIGS. 26 (D) and 27 (B). The jackpot symbol determination counter C7 (random numbers 7, 0 to 13) is, as shown in FIG. 26D, 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 4 msec, and as a result, the jackpot symbol corresponding to the random value is also created as random data every 4 msec. .

  As shown in FIG. 27 (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 4 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. In FIG. 27B, a big hit 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. 25, that is, in the processing of step S353, if the big hit flag F1 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 it out. The jackpot symbol corresponding to the jackpot symbol data is determined as a symbol to be stopped and displayed on the image display unit 30 of the special symbol display device 6 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 F1 is 0, the process proceeds to step S348, and the CPU 102 determines whether or not the value of the reach flag F2 is 0. If the value of reach flag F2 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 30 of the special symbol display device 6 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 F2 is 1, the process proceeds to step S350, and the CPU 102 determines whether or not the value of the reach state flag F3 is 0. If the value of reach state flag F3 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 plus or minus 1 symbols. The symbol data is read out, and a reach out symbol other than the plus or minus one symbol corresponding to the read out symbol data is determined as a symbol to be stopped and displayed on the image display unit 30 of the special symbol display device 6 this time, Store in the storage area.

  On the other hand, when the value of reach mode flag F3 is not 0 (NO in step S350), that is, when the value of reach mode flag F3 is 1, the process proceeds to step S352, and CPU 102 determines whether plus or minus 1 symbol. The symbol information stored in the reach symbol storage buffer is read out, and the reach symbol symbol of the plus or minus one symbol corresponding to the read out symbol data is stopped and displayed on the image display unit 30 of the special symbol display device 6 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 the processes in step S349, step S351, step S352, and step S353 is completed, the CPU 102 ends the special symbol determination process (step S346), and proceeds to the special symbol control process in step S354. FIG. 28 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. 29 in step S356.

  FIG. 29 is a flowchart showing the special symbol variation display process (step S356). When this special symbol variation display process is executed, CPU 102 determines whether or not the value of big hit flag F1 is 0 in step S358. If the value of the big hit flag F1 is not 0 (NO in step S358), that is, if the value of the big hit flag F1 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, 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 F1 is 0, the process proceeds to step S362, and the CPU 102 determines whether or not the value of the reach flag F2 is 0. If the value of the reach flag F2 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 F2 is 1, the process proceeds to the process of step S364, and the CPU 102 determines whether or not the value of the reach state flag F3 is 0. If the value of reach state flag F3 is 0 (YES in step S364), that is, the symbol data acquired this time is other than plus or minus 1 symbol in step S351 of the special symbol determination process (step S346) described above. If the reach out-of-reach symbol data is obtained from the reach symbol storage buffer, 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 F3 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 of 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 the plurality of variation patterns. The variation acquired in the random number acquisition processing in step S310 is selected. It is determined by the value of the pattern determination counter C8 (random number 8, 0 to 51).

  Here, when the process of step S366 is completed, the CPU 102 proceeds to step S367, where YES is selected in step S327 of the above-described falling lottery stop process (FIG. 21), and the lottery for dropping the big hit probability from the high probability is stopped. If it has, the falling lottery stop cancellation process is executed to start the lottery again. FIG. 30 is a flowchart showing the falling lottery stop cancellation process (step S367). When the falling lottery stop cancellation process is executed, the CPU 102 first stops the lottery in which the falling lottery flag F6 is set to 1, that is, the big hit probability falls from a high probability in the process of step S368. It is determined whether or not. If NO in step S368, that is, if the lottery for dropping the big hit probability from the high probability has not been stopped, the CPU 102 ends the falling lottery stop release processing and proceeds to the processing in step S372.

  On the other hand, if YES in the process of step S368, that is, if the lottery for dropping the big hit probability from the high probability is stopped, the CPU 102 proceeds to the process of step S369 and releases the stop. Therefore, the lottery for dropping the big hit probability from the high probability and the lottery for stopping the lottery for dropping the big hit probability from the high probability are started again by the process of step S369. Then, the process shifts to the process of step S370, the CPU 102 sets the fall lottery flag F6 to 0, shifts to the process of step S371, outputs a fall lottery start effect command to the display control circuit 111, and the special symbol display device. The lottery for dropping the big hit probability from the high probability is canceled in the image display unit 6 of 6, and the lottery for dropping the big hit probability from the high probability from the next slot game and the lottery for stopping the lottery are resumed. An effect display that suggests The falling lottery start effect display will be described in detail later. When the process of step S371 is completed, the falling lottery stop cancellation process is terminated, and the process proceeds to step S372.

  That is, in the falling lottery stop cancellation process of step S367, when the lottery drawing flag F6 is set to 1 and the lottery for dropping the big hit probability from the high probability is stopped, the reach state flag F3 is set to 1 and plus or minus 1 It is executed when display control circuit 111 is instructed to display any one of variation pattern 21, variation pattern 31, variation pattern 51, and variation pattern 61 related to the deviation of reach as a symbol. Yes. Therefore, the drop lottery start effect display indicates that the player has maintained the big hit probability without falling from a high probability, and that the lottery to drop the big hit probability from the high probability and the lottery to stop the lottery have been resumed. Therefore, the gameability of the gaming machine 1 is improved. In addition, when the variation pattern 21 or the variation pattern 31 is displayed, the case where the falling lottery start effect display is displayed and the case where it is not displayed are mixed, so that the gaming property of the gaming machine 1 is further improved.

  When the process of step S360, step S361, step S365, or step S367 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 and 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 special symbol display device 6 has displayed the variation pattern related to the big hit or the reach, 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. 31, 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 30 of the special symbol display device 6. Game). FIG. 31 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 6. 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 6. The transmission data shown in FIG. 31 is output for a fixed display after variable display (scroll display) on the symbol display unit 8, the middle symbol display unit 9, and the right symbol display unit 10.

  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 8, 9, and 10 of the special symbol display device 6. Until then, it is defined that five commands are transmitted as display control commands. As shown in FIGS. 31A and 31B, 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 medium special symbol designation command and all symbol stop designation commands are transmitted.

  As shown in FIG. 31, the five special commands are transmitted when the time T1 elapses after the first variation pattern designation command is transmitted, and the left special symbol designation command is 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 time T has elapsed since the variation pattern designation command was transmitted. Therefore, this time T is a special symbol variation time, that is, a time from when the special symbol (the left special symbol, the middle special symbol, and the right special symbol) starts to fluctuate on the special symbol display device 6 until it stops. 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 variation pattern designation command transmitted first includes the value of the variation pattern determination counter C8 (random numbers 8, 0 to 51) acquired in the random number acquisition process in step S310 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. 26, and the stop symbol (definite symbol) in the left column is instructed. The right special symbol designation command includes 14 types corresponding to the right special symbols 1 to 14 shown in FIG. 26, and designates a stop symbol (determined symbol) in the right column. The middle special symbol designation command is prepared in 14 types corresponding to the medium special symbols 1 to 14 shown in FIG. 26, and designates a middle row stop symbol (determined symbol). 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 to change until it is fixedly displayed after being stopped is displayed by each of the symbol display units 8, 9, and 10 of the special symbol display device 6.

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

  In addition, the aspect until each symbol display part 8,9,10 stops from a fluctuation | variation start may be other than above, and various aspects can be considered. For example, a time difference may be provided when each of the symbol display units 8, 9, and 10 starts changing, or may be stopped simultaneously when each of the symbol display units 8, 9, and 10 stops changing. Furthermore, the order in which the symbol display units 8, 9, and 10 start changing may be changed, or the order in which the symbol display units 8, 9, and 10 stop changing 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 the present change display will become, gameability will improve, and a player's willingness to play will increase.

  In addition, the special symbol stop means not only the state where it is completely stopped, but also a state where, for example, several frames are slightly moved up and down on each of the symbol display portions 8, 9, 10 (hereinafter, this state is referred to as such). 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.

  Returning to FIG. 28, when the process proceeds to step S <b> 373, the CPU 102 determines whether or not the special symbol variation time T (see FIG. 31) 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.

  After shifting to the process of step S374, the CPU 102 executes a process of confirming and displaying the special symbol determined in the special symbol determination process of step S346 on the special symbol display device 6 as described above, and proceeds to the process of step S375. Then, the value of the reach flag F2 is set to 0, the process proceeds to step S376, and the value of the reach mode flag F3 is set to 0. 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 S371 and S372. , Do nothing. When the process of step S376 is completed, the CPU 102 ends the special symbol control process (step S354).

  When the process proceeds to step S378, the CPU 102 determines whether or not the special symbol is confirmed and displayed on the special symbol display device 6 here. If the special symbol is not displayed (NO in step S378), the special symbol is displayed. The symbol game process (step S317) is terminated. On the other hand, when it is determined in the process of step S378 that the special symbol is confirmed and displayed on the special symbol display device 6 (YES in step S378), the process proceeds to step S380, and the CPU 102 receives the big hit here. It is determined whether or not the value of the flag F1 is 1. If NO in step S380, that is, if the value of the big hit flag F1 is 0, the CPU 102 proceeds to the process of step S434. On the other hand, when the value of big hit flag F1 is 1 (YES in step S380), the process proceeds to step S385, and CPU 102 executes the big hit process shown in FIG.

  FIG. 32 is a flowchart showing the big hit process (step S385). When the jackpot process (step S385) is executed, the CPU 102 first reduces the jackpot probability increased in the process of step S426 described later in the process of step S389 in the process of step S389. . 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, Therefore, if the jackpot probability is not set to a high probability, the process of step S389 is skipped.

  When the process of step S389 is completed, the CPU 102 proceeds to the process of step S390, sets 0 to the probability variation flag F7, proceeds to the process of step S392, and determines whether it is during the interval time. This interval time is the time during which the big prize opening (attacker) 7 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 7. Then, the process proceeds to step S396, and the CPU 102 determines whether or not the preset opening time 30 of the predetermined prize winning opening 7 has expired, and NO in the process of step S396, that is, If it is determined that the opening time 30 seconds of the big prize opening 7 has not expired, the process proceeds to step S398 to determine whether the value of the counter D is 10 or more. The counter D is a main control circuit 44 for counting the number of game balls won in the big prize opening 7 until the opened big prize opening 7 is closed after the opening time of the big prize opening 30 seconds elapses. Is counted up when the count switch 117 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 D is determined to be less than 10, the CPU 102 ends the jackpot process. On the other hand, if it is determined as YES in the process of step S396 or the process of step S398, that is, if it is determined that the opening time 30 seconds of the special winning opening 7 has expired, or the value of the counter D is determined to be 10 or more. If YES in step S400, the process advances to step S400, and the CPU 102 drives and controls the solenoid 106 to close the special winning opening 7. Then, the CPU 102 proceeds to the process of step S401, sets the value of the counter D to 0, proceeds to the process of step S402, and increments (adds 1) the value of the counter E. This counter E is a counter set in the main control circuit 44 in order to count how many times the big winning opening 7 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 7 is closed, the count is incremented, and when the power is turned on, it is initialized and set to 0.

  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 118 is turned on, that is, the gaming ball that has passed the specific area of the big winning opening 7. When it is determined whether or not the game ball has passed the specific area of the big winning opening 7 and the continuous winning switch 118 is turned 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 E 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 7 is opened, that is, whether or not the number of rounds in the big hit game has reached 16 times. If YES in step S406, that is, if it is determined that the value of the counter E 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 118 is not turned on and the game ball does not pass the specific area of the big winning opening 7, or the counter E If 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 E to 0, proceeds to the process of step S408, and sets the value of the big hit flag F1. Set to 0 to end the jackpot processing.

  Returning to FIG. 18, when the process proceeds to step S410, the CPU 102 determines whether or not the value of the big hit flag F1 is 0, that is, whether or not all of the predetermined big hit processing (step S385) has been completed, and the big hit flag F1. If the value is not 0 (NO in the process of step S410), that is, if the value of the big hit flag F1 is 1, it is determined that all the predetermined big hit processes have not been completed, and this special symbol game process (step S317) is terminated. On the other hand, when the value of big hit flag F1 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. 29). It is determined whether or not it is a numerical symbol of the second order, that is, whether or not it is a specific big symbol 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 S412 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 hit based on the fact that the specific big win symbol is confirmed and displayed. Increase the lottery probability to 5/315. This is done by changing only 7 to the big hit random numbers instead of the big hit random numbers 7, 33, 77, 111 and 222 among the big hit random numbers composed of 0 to 350 described above. 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 F7, and proceeds to the process of step S434.

  On the other hand, as described above, the CPU 102 proceeds to the process of step S434 also in the case of NO in step S380 and NO in step S411, that is, when the big hit symbol acquired this time is not the specific big bonus symbol. Then, the value of the counter B incremented (added by 1) in the process of step S308 (FIG. 16) is decremented (subtracted by 1), and the process proceeds to the process of step S436 to execute the hold LED extinguishing control process.

  FIG. 33 is a flowchart showing the hold LED extinguishing control process (step S436). When the hold LED extinguishing control process is executed, the CPU 102 first determines whether or not the value of the counter B is 1 or more in the process of step S438, and if the value of the counter B is not 1 or more (in step S438) NO), that is, if the value of the counter B is 0, the hold LED extinguishing control process (step S436) is terminated, and the process proceeds to the process of step S50 of the main game process (FIG. 5). On the other hand, if YES in the process of step S438, that is, if the value of the counter B is 1 or more, the process proceeds to the process of 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 turn-off control process is finished.

  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 this step S50, the CPU 102 performs the big hit processing from the external information terminal 109 described above, during the falling state, during the falling lottery, and stops the falling lottery based on the big hit flag F1, the falling lottery flag F6 or the probability variation flag F7. A signal indicating that the middle or big hit probability is increasing 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 accordingly performs the processing in step S50. When the manager is in the state of various game 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 when the big hit is falling, and the falling lottery is being executed while the big hit probability is increasing The player's payout ball per unit time when the falling lottery was stopped while the jackpot, the jackpot probability was increasing, or considering various gaming conditions (for example, when the jackpot probability was not rising) The number of base spheres etc. will 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.

  Note that such game data may be displayed on the special symbol display device 6 provided 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 C13 (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 (4 msec), but the time required to execute these processes is not the same every time. Accordingly, the time of 4 msec for generating the reset interrupt needs to be set with a margin, and the remaining time still occurs when the CPU 102 completes the process of step S50. In step S60, this remaining time is used to update the values of the random number counters C1 to C13. For example, the values of the random number counters C1 to C13 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-C13 by a predetermined numerical formula etc. is performed.

  In addition, without updating the values of the respective random number counters C1 to C13, specific random number counters such as a big hit determination counter C1, a big hit symbol determination counter C7, a falling lottery stop determination counter C9, a positive variation falling determination counter C10, Only the random number counter that greatly affects the player's profit, such as the hit determination counter C11, may be updated. The value of each of the random number counters C1 to C13 may be updated by a reset interrupt (4 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. In this way, by updating the predetermined random number counter using the remaining time of the reset interrupt that is repeatedly executed every 4 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 device 6 this time. The variation pattern 1 is a variation pattern determination counter C8. Regardless of (random numbers 8, 0 to 51), a 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 it is variably displayed on the special symbol display device 6. .

  The variation pattern 21 is a variation pattern that is selected when a reach-out symbol of plus or minus 1 symbol or a reach-out symbol other than plus or minus 1 symbol is determined as a symbol to be stopped and displayed on the special symbol display device 6 this time, Specifying a variation pattern 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 command is transmitted from the main control circuit 44 to the display control circuit 111, the special symbol display device 6 displays the command in a variable manner.

  The variation pattern 22 is a variation pattern selected when a big hit symbol is determined as a symbol to be stopped and displayed on the special symbol display device 6 this time, and an odd number of big hit symbols (specific big bonus symbols) are stored in the big hit symbol storage buffer. Store (obtained numerical value of jackpot symbol determination counter C7 (random numbers 7, 0 to 13) is 0, 2, 4, 6, 8, 10, 12, probability 1/2), acquired numerical value of variation pattern determination counter C8 1 to 5 (probability 5/52) 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 the variation pattern designation command corresponding to the variation pattern 22 is displayed from the main control circuit 44 when the obtained numerical value of the variation pattern determination counter C8 is 0 to 5 (probability 6/52). By being sent to the control circuit 111, it is variably displayed on the special symbol display device 6.

  Like the variation pattern 21, the variation pattern 31 is selected when the reach / decrease symbol of the plus / minus 1 symbol or the reach / displace symbol other than the plus / minus 1 symbol is determined as the symbol to be stopped and displayed on the special symbol display device 6 this time. If the obtained value of the variation pattern determination counter C8 is 25 to 31 (probability 7/52) or 30 to 51 (probability 30/52), the variation pattern designation command corresponding to the variation pattern 31 is By being transmitted from the main control circuit 44 to the display control circuit 111, the special symbol display device 6 is variably displayed.

  Similar to 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 device 6 this time, and an odd number of big hit symbols ( (Special big win symbol) is stored (acquired value of big hit symbol determining counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and acquired numerical value of 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, If the obtained numerical value of the variation pattern determination counter C8 is 6 to 10 (probability 5/52), the variation pattern designation command corresponding to the variation pattern 32 is the main control circuit 44. By being sent to the al display control circuit 111, it is variably displayed on the special symbol display device 6.

  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 device 6 this time. Stored (acquired numerical value of jackpot symbol determination counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and acquired numerical value of variation pattern determination counter C8 is 0 (probability 1/52) In this case, 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 the variation is displayed on the special symbol display device 6.

  The variation pattern 51 is a variation pattern that is selected when the symbol of the plus / minus 1 symbol is determined to be stopped and displayed on the special symbol display device 6 this time, and the obtained numerical value of the variation pattern determination counter C8 is In the case of 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, and is variably displayed on the special symbol display device 6. .

  Similar to 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 device 6 this time, and an odd number of big hit symbols ( (Specific big bonus symbol) is stored (obtained numerical value of jackpot symbol determining counter C7 is 0, 2, 4, 6, 8, 10, 12, probability 1/2), and acquired numerical value of variation pattern determining counter C8 is 11 to 11. 35 (probability 25/52) or an even number of big hit symbols (usually big hit symbols) 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, When the obtained numerical value of the variation pattern determination counter C8 is 11 to 26 (probability 16/52), the variation pattern designation command corresponding to the variation pattern 52 is the main control. By being transmitted from the road 44 to the display control circuit 111, it is variably displayed on the special symbol display device 6.

  Similar to the variation pattern 51, the variation pattern 61 is a variation pattern that is selected when a symbol out of reach of one plus or minus one symbol is determined as a symbol to be stopped and displayed on the special symbol display device 6 this time. When the acquired numerical value of the 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, whereby the special symbol display device 6 is displayed in a variable manner.

  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 device 6 this time, and an odd number of big hit symbols ( (Specific big win symbol) is stored (obtained numerical 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 an even number of big hit symbols (usually big hit symbols) 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, When the obtained numerical value of the variation pattern determination counter C8 is 27 to 51 (probability 25/52), the variation pattern designation command corresponding to the variation pattern 62 is the main control. By being transmitted from the road 44 to the display control circuit 111, it is variably displayed on the special symbol display device 6.

  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 the reach action of these variation patterns is viewed 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 that is displayed only when a big hit is made, and is displayed only when a specific big symbol is displayed. When it is done, it is convinced that it will be a big hit with a specific bonus symbol.

  Next, based on the input of various display control commands from the main control circuit 44 to the display control circuit 111, various variation patterns, effects, and the like are displayed on the image display unit 30 of the special symbol display device 6. In this case, display processing executed by the display control circuit 111 will be described. FIG. 35 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 S701). When completing the initialization process in step S701, the CPU 140 proceeds to the random number update process in step S703. The CPU 140 executes a main routine (each program stored in the ROM 142 of the display control circuit 111), that is, each process of steps S703 to S743 described below, every reset interrupt (4 msec).

  FIG. 36 is a list of random numbers handled in the display control circuit 111. As shown in FIG. 36, in the main control circuit 44, various counters C21 to C25 (random numbers 21 to 25) are set as random numbers for randomly setting the display mode of each effect display. CPU140 updates the value regarding each counter C21-C25 by the random number update process of step S703.

  The falling lottery stop effect display determination counter C21 (random numbers 21, 0 to 99) is a lottery that causes the image display unit 30 of the special symbol display device 6 to drop the big hit probability from a high probability and the lottery that stops the falling lottery. This is a random number counter for determining a falling lottery stop effect display that directly or indirectly indicates that it has stopped, starting from 0 when the power is turned on, and incrementing (adding 1) every reset interrupt (4 msec) ) However, when this random number counter C21 becomes 100, it is rewritten to 0. Although not shown, five types of falling lottery stop effect display are prepared, and one of the five types of falling lottery stop effect display is set to the value of the counter C21 for determining the lottery lottery stop effect display. Based on the selection.

  The falling lottery start effect display determination counter C22 (random numbers 22, 0-99) is released from the lottery stop and the image display unit 30 of the special symbol display device 6 is released from stopping the lottery to drop the big hit probability from a high probability. This is a random number counter for determining a fall lottery start effect display that displays an effect that suggests that the lottery that stops the fall lottery will be resumed, starting from 0 when the power is turned on, and every reset interrupt (4 msec) Is incremented (added by 1). 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 high-probability suggestion effect display determination counter C23 (random numbers 23, 0 to 99) causes the image display unit 30 of the special symbol display device 6 to display effect that suggests that the jackpot probability is high. A random number counter for determining a suggestive effect display, which starts from 0 when the power is turned on, and is incremented (added by 1) every reset interrupt (4 msec). However, when this random number counter C23 becomes 100, it is rewritten to 0. Although not shown, five types of high-probability suggestion display are prepared, and one of the five types of high-probability suggestion display is set to the value of the high-probability suggestion display determination counter C23. Based on the selection.

  The counter C24 for abortion effect display determination (random numbers 24, 0 to 99) indicates that the high probability suggestion effect display has been aborted on the image display unit 30 of the special symbol display device 6 and the jackpot probability has fallen from the high probability. This is a random number counter for determining an aborted effect display for suggesting an effect display, which starts from 0 when the power is turned on and is incremented (added by 1) every reset interrupt (4 msec). However, when this random number counter C24 becomes 100, it is rewritten to 0. Although not shown, five types of censorship effect display are prepared, and any one of the five types of censorship effect display is selected based on the value of the counter C24 for determining the censorship effect display. It has become.

  The fall probability reduction effect display determination counter C25 (random numbers 25, 0 to 99) increases the probability that the fall lottery that causes the big hit probability to fall from the high probability is stopped on the image display unit 30 of the special symbol display device 6. And a random number counter for determining the fall probability reduction effect display for direct or indirect effect display that the probability of falling from a high probability in the fall lottery is reduced. It starts from 0 and is incremented (added by 1) every reset interrupt (4 msec). However, when this random number counter C25 becomes 100, it is rewritten to 0. Although not shown, five types of fall probability reduction effect display are prepared, and one of these five types of fall probability reduction effect display is set to the value of the fall probability reduction effect display determination counter C25. Based on the selection.

  Returning to FIG. 35, in step S703, the CPU 140 determines the falling lottery stop effect display determination counter C21, the falling lottery start effect display determination counter C22, the high probability suggestion effect display determination counter C23, and the abortion effect display determination. When the random number update processing of the counter C24 and the fall probability reduction effect display determination counter C25 is completed, the process proceeds to step S705, where the fall lottery stop effect is performed in step S330 of the above-described fall lottery stop processing (FIG. 21). In step S371 of the falling lottery stop cancellation process (FIG. 30), the fall lottery start effect command is changed to the highly probable suggestion effect command in step S321 of the high probability suggestion effect process (FIG. 19). 24) in step S344 and step S336, the abort effect command and the fall probability Lowering effect command determines whether or not the input from the main control circuit 44. In step S705, when the strobe signal is input from the main control circuit 44, the CPU 140 recognizes these effect commands.

  If NO in step S705, that is, if no effect command is input from the main control circuit 44, the process proceeds to step S737. On the other hand, if YES in the process of step S705, that is, if any effect command is input from the main control circuit 44, the process proceeds to step S707, and the CPU 140 executes an effect display process.

  FIG. 37 is a flowchart showing the effect display process (step S707). When this effect display process is executed, the CPU 140 first determines in step S709 whether or not the effect command input this time is a falling lottery stop effect command. If NO in step S709, that is, if the effect command input this time is not a falling lottery stop effect command, the CPU 140 proceeds to step S715.

  On the other hand, if YES in the process of step S709, that is, if the effect command input this time is a falling lottery stop effect command, the process proceeds to the process of step S711, and the CPU 140 selects one of the counters C21 to C25 described above. The current value of the falling lottery stop effect display determination counter C21 is acquired and stored in the acquired numerical value storage area of the RAM 141, the process proceeds to step S713, and the falling lottery stop effect display acquired in the process of step S711 is obtained. Based on the value of the determination counter C21, one fall lottery stop effect display is selected from five types of fall lottery stop effect displays, and an effect image such as a character or background corresponding to the selected fall lottery stop effect display Is displayed on the image display unit 30 of the special symbol display device 6 on the VDP 143. That. When the falling lottery stop effect display process in step S713 is completed, the CPU 140 proceeds to the process in step S715.

  That is, in the processing from step S709 to step S713, the value of the falling lottery stop effect display determination counter C21 (random numbers 21, 0 to 99) is the timing at which the display control circuit 111 receives the falling lottery stop effect command from the main control circuit 44. Is acquired, and one fall lottery stop effect display is determined from the above-described five types of fall lottery stop effect displays and displayed on the image display unit 30 of the special symbol display device 6. Thereby, the uniformity and irregularity of the acquired numerical value of the falling lottery stop effect display determination counter C21 are ensured, and accordingly when the falling lottery stop effect display is displayed on the image display unit 30 of the special symbol display device 6, Uniformity and irregularity of the contents of the falling lottery stop effect display are guaranteed, and the gaming property of the gaming machine 1 is improved.

  The contents of the fall lottery stop effect display are not particularly limited, but directly or indirectly display that the lottery to drop the jackpot probability from a high probability and the lottery to stop the fall lottery are stopped. Displayed characters such as “High probability maintained!”, “Falling lottery stopped!”, “Probability guaranteed!”, “Chance!” Etc. are displayed during the slot game or immediately after the end of the slot game. Anyway. Alternatively, these characters may be displayed continuously during the fall lottery stop effect display period, or may be displayed in pieces during the fall lottery stop effect display period.

  When the process proceeds to step S715, the CPU 140 determines whether or not the effect command input this time is a fall lottery start effect command. If NO in step S715, that is, if the effect command input this time is not a falling lottery start effect command, the CPU 140 proceeds to the process of step S721.

  On the other hand, if YES in the process of step S715, that is, if the effect command input this time is a fall lottery start effect command, the process proceeds to step S717, and the CPU 140 selects one of the counters C21 to C25 described above. The current value of the falling lottery start effect display determination counter C22 is acquired and stored in the acquired numerical value storage area of the RAM 141, the process proceeds to step S719, and the falling lottery start effect display acquired in the process of step S717 is obtained. Based on the value of the determination counter C22, one fall lottery start effect display is selected from five types of fall lottery start effect displays, and an effect image such as a character or background corresponding to the selected fall lottery start effect display Is displayed on the image display unit 30 of the special symbol display device 6 on the VDP 143. That. When the falling lottery start effect display process in step S719 ends, the CPU 140 proceeds to the process in step S721.

  That is, in the processing from step S715 to step S719, the value of the falling lottery start effect display determination counter C22 (random numbers 22, 0 to 99) at the timing when the display control circuit 111 receives the falling lottery start effect command from the main control circuit 44. Is acquired, and one falling lottery start effect display is determined from the above-described five types of falling lottery start effect displays, and is displayed on the image display unit 30 of the special symbol display device 6. Thereby, the uniformity and irregularity of the acquired numerical value of the falling lottery start effect display determination counter C22 are ensured, and accordingly, when the falling lottery start effect display is displayed on the image display unit 30 of the special symbol display device 6, The uniformity and irregularity of the contents of the falling lottery start effect display are ensured, and the gaming property of the gaming machine 1 is improved.

  Although the content of the drop lottery start effect display is not particularly limited, it suggests that the lottery that causes the jackpot probability to fall from a high probability is released and the lottery that stops the fall lottery and the falling lottery is resumed For example, “May fall!” “May start a lottery!” “Lottery, surely stop!” “It ’s not a big deal!” “Okay, high probability!” “Surely come!” It may be displayed during the game period or immediately after the end of the slot game. Alternatively, these characters may be continuously displayed during the fall lottery start effect display period, or may be displayed in pieces during the fall lottery start effect display period.

  When the process proceeds to step S721, the CPU 140 determines whether or not the effect command input this time is a high-probability suggestion effect command. If NO in step S721, that is, if the effect command input this time is not a high probability suggestion effect command, the CPU 140 proceeds to the process of step S727.

  On the other hand, if YES in the process of step S721, that is, if the effect command input this time is a high-probability suggestion effect command, the process proceeds to step S723, and the CPU 140 includes the counters C21 to C25 described above. The current value of the high-probability suggestion display determination counter C23 is acquired, stored in the acquired numerical value storage area of the RAM 141, the process proceeds to step S725, and the high-probability suggestive effect display acquired in step S723 is acquired. Based on the value of the determination counter C23, one high probability suggestion effect display is selected from the five types of high probability suggestion effect displays, and an effect image such as a character or background corresponding to the selected high probability suggestion effect display Is displayed on the VDP 143 on the image display unit 30 of the special symbol display device 6. When the high-probability suggesting effect display process in step S725 is completed, the CPU 140 proceeds to the process in step S727.

  That is, in the processing from step S721 to step S725, the value of the high probability suggestion effect display determination counter C23 (random numbers 23, 0 to 99) at the timing when the display control circuit 111 receives the high probability suggestion effect command from the main control circuit 44. Is obtained, and one high probability suggestion effect display is determined from the above-described five types of high probability suggestion effect displays, and is displayed on the image display unit 30 of the special symbol display device 6. Thereby, the uniformity and irregularity of the acquired numerical value of the counter C23 for determining the high probability suggestion effect display are ensured, and accordingly, when displaying the high probability suggestion effect display on the image display unit 30 of the special symbol display device 6, The uniformity and irregularity of the content of the high-probability suggesting effect display is guaranteed, and the gaming property of the gaming machine 1 is improved.

  In the case of YES in the process of step S721, an effect continuation number designation command for instructing an effect continuation number of the high probability suggestion effect display is input from the main control circuit 44 together with the high probability suggestion effect command. Based on the instruction of the designated command, the high probability suggestion effect display is displayed on the image display unit 30 of the special symbol display device 6 over the plurality of slot games in the high probability suggestion effect display process of step S725.

  The contents of the high-probability suggestion display are not particularly limited, but characters that suggest that the jackpot probability is high, such as “may be high probability!”, “Maybe fallen lottery!” “Maybe!” “May be good!” “Big hit is close!” Etc. These characters are sequentially changed each time a slot game is played, and a high-probability suggestion effect display period (executed based on a command to specify the number of times to continue the effect) During a plurality of (3 to 7 times) slot games).

  In step S727, the CPU 140 determines whether the effect command input this time is an abort effect command. If NO in step S727, that is, if the effect command input this time is not an abortion effect command, the CPU 140 proceeds to the process of step S733.

  On the other hand, if YES in the process of step S727, that is, if the effect command input this time is an abort effect command, the process proceeds to step S729, and the CPU 140 cancels out of the counters C21 to C25 described above. The current value of the effect display determination counter C24 is acquired and stored in the acquired numerical value storage area of the RAM 141. The process proceeds to step S731, and the value of the abortion effect display determination counter C24 acquired in the process of step S729. Is selected from among the five types of censored effect display, and an effect image such as a character or background corresponding to the selected censored effect display is displayed on the VDP 143 as an image display of the special symbol display device 6. An abort effect display process to be displayed by the unit 30 is executed. When the abort effect display process in step S717 is completed, the CPU 140 proceeds to the process in step S733.

  That is, in the processing from step S727 to step S731, at the timing when the display control circuit 111 receives an abort effect command from the main control circuit 44, the value of the abort effect display determination counter C24 (random numbers 24, 0 to 99) is acquired. One abort effect display is determined from the five types of abort effect displays described above and displayed on the image display unit 30 of the special symbol display device 6. Thereby, the uniformity and irregularity of the numerical value acquired by the counter C24 for determining the discontinuation effect display are ensured, and when the discontinuation effect display is displayed on the image display unit 30 of the special symbol display device 6, the discontinuation effect display is performed. The uniformity and irregularity of the contents are ensured, and the gaming property of the gaming machine 1 is improved.

  The contents of the discontinuation effect display are not particularly limited, but characters that indicate that the jackpot probability has fallen from a high probability, for example, “may have fallen!” “May not be a lottery!” “Why? “!”, “That!” And “Gun Valley!” May be displayed during the slot game or immediately after the end of the slot game.

  When the process proceeds to step S733, the CPU 140 acquires the current value of the fall probability reduction effect display determination counter C25 among the counters C21 to C25 described above, and stores it in the acquired numerical value storage area of the RAM 141. The process shifts to one, and one fall probability reduction effect display is selected from five types of fall probability reduction effect display based on the value of the fall probability fall effect display determination counter C25 acquired in step S733. Then, a fall probability reduction effect display process for causing the VDP 143 to display an effect image such as a character or background corresponding to the selected fall probability reduction effect display on the image display unit 30 of the special symbol display device 6 is executed. Then, when the fall probability reduction effect display process in step S735 is finished, the CPU 140 ends the effect display process in step S707 and proceeds to the process in step S737.

  That is, in the processing of step S733 and step S735, the value of the fall probability reduction effect display determination counter C25 (random numbers 25, 0 to 99) at the timing when the display control circuit 111 receives the fall probability reduction effect command from the main control circuit 44. Is acquired, and one fall probability reduction effect display is determined from the above-described five types of fall probability reduction effect displays, and is displayed on the image display unit 30 of the special symbol display device 6. Thereby, the uniformity and irregularity of the numerical value acquired by the fall probability reduction effect display determination counter C25 are ensured, and accordingly, when the fall probability reduction effect display is displayed on the image display unit 30 of the special symbol display device 6, The uniformity and irregularity of the contents of the fall probability reduction effect display are ensured, and the gaming property of the gaming machine 1 is improved.

  The content of the fall probability reduction effect display is not particularly limited, but the character that displayed directly or indirectly that the probability that the jackpot probability falls from a high probability and the fall probability is reduced, For example, characters such as “falling probability drop!”, “Falling lottery may stop!”, “Reserve a lot of reserved balls!”, “Great!”, “Chance!”, Etc. during the slot game or immediately after the end of the slot game May be displayed.

  Moreover, these fall lottery stop effect display, fall lottery start effect display, high probability suggestion effect display, discontinuation effect display, and fall probability reduction effect display need not be described, and effect images using various characters and various backgrounds are used. It is displayed on the image display unit 30 of the special symbol display device 6 and appeals to the player directly or indirectly 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 is supposed to be. 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 a lottery process 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. In addition, the high probability suggesting effect display may be displayed together with the falling lottery stop effect display, the falling lottery start effect display, or the falling probability lowering effect display. In such a case, priority is given to only one of them. May be displayed.

  Returning to FIG. 35, when the process proceeds to step S <b> 737, the CPU 140 changes according to the process of step S <b> 360, step S <b> 361, step S <b> 363, step S <b> 365, or step S <b> 366 of the special symbol change display process (FIG. 29). It is determined whether or not a pattern designation command is input from the main control circuit 44. If NO in step S737, that is, if a variation pattern designation command is not input from the main control circuit 44, the process proceeds to step S741. On the other hand, if YES in the process of step S737, that is, if a variation pattern designation command is input from the main control circuit 44, the process proceeds to step S739, and the CPU 140 executes the variation pattern display process, and then executes step S741. Move on to processing.

  Although detailed description of the variation pattern display process is omitted, in short, the variation pattern designation command input in the process of step S737 is any variation pattern, that is, the above-described ten variation patterns (variation patterns). 1, fluctuation pattern 21, fluctuation pattern 22, fluctuation pattern 31, fluctuation pattern 32, fluctuation pattern 4, fluctuation pattern 51, fluctuation pattern 52, fluctuation pattern 61 and fluctuation pattern 62) which fluctuation pattern is designated. In the specified variation pattern, the special symbol display device 6 of the special symbol display device 6 performs a scroll display in which the special symbol is pseudo-rotated in a predetermined direction, and a reach action using a predetermined character or background image. This is a process of displaying the effect image.

  Then, in the variation pattern display process, the special symbol that is finally stopped and displayed on the image display unit 30 (left symbol display unit 8, middle symbol display unit 9, right symbol display unit 10) of the special symbol display device 6 is The left special symbol designation command, the right special symbol designation command, the middle special symbol designation command, and the all symbol stop designation command inputted from the main control circuit 44 are determined. In the processing of step S737 and step S739, the strobe signal is input from the main control circuit 44 in the same manner as in the processing of step S705, so that the CPU 140 causes these variation pattern designation commands, left special symbol designation commands, Recognize right special symbol designation command, middle special symbol designation command and all symbol stop designation command.

  When the process proceeds to step S741, the CPU 140 executes other processes. The CPU 140 executes various processes other than the processes in steps S701 to S739 described above in the display main control process. Since these processes are not particularly related to the present invention, other processes in step S741 are performed. The explanation is omitted.

  When the process of step S741 ends, the CPU 140 proceeds to the process of step S743 and executes a random number update process. This performs a loop process that continuously updates the values of the random number counters C21 to C25 (see FIG. 36) in the random number update process of step S703 described above until the next reset interrupt occurs.

  The process of step S743 is similar to the random number update process of step S60 performed in the main game process described above, and the values of the random number counters C21 to C25 are updated using the remaining time of the display main control process. For example, a process of continuously incrementing (adding 1) or decrementing (decrementing 1) the values of the random number counters C21 to C25 until the remaining time is consumed, or each random number counter according to a predetermined mathematical expression. The process etc. which continue updating the value of C21-C25 are performed.

  Next, a specific game flow of the gaming machine 1 that is executed based on the above-described main game process, display main control process, and the like will be described with reference to FIG. FIG. 38 is an explanatory diagram showing the flow of the game from when the specific big win symbol is fixedly displayed and the jackpot probability rises to a high probability and then falls to the normal probability again.

  After power is turned on to the gaming machine 1, the game ball launched from the hitting ball launching device 43 to the game area 5 on the game board 21 wins the start winning opening 11 by operating the hitting operation handle 2 of the player. As a result of the winning, a slot game for scrolling the special symbols in a predetermined direction is displayed on the image display unit 30 of the special symbol display device 6. While the slot game related to the winning is displayed in a predetermined variation pattern on the image display unit 30 of the special symbol display device 6, if one game ball wins the start winning opening 11, the hold LED 25a is turned on. Thereafter, the hold LEDs 25b, 25c, and 25d are sequentially turned on each time one game ball is won at the start winning opening 11, and after that, even if the game ball wins the start winning opening 11, it becomes an overflow ball and is held. Not remembered as a sphere.

  When the slot game displayed on the image display unit 30 of the special symbol display device 6 is finished and a predetermined symbol is finally displayed as a combination of special symbols, one corresponding hold LED 25 is turned off (hold LED 25d, 25c, 25b, and 25a are turned off in this order), and the next slot game is started on the image display unit 30 of the special symbol display device 6 again. Thereafter, in the gaming machine 1, when the game ball wins the start winning opening 11, the game related to the special symbol is repeated in this way.

  Here, in the image display unit 30 of the special symbol display device 6, when the special symbol of the left symbol display unit 8 and the special symbol of the right symbol display unit 10 are a combination of the same special symbols, the reach is determined. Reach action is displayed (variation patterns 21, 22, 31, 32, 4, 51, 52, 61, 62, special symbol variation time T = 13 to 42 seconds), and then the combination of special symbols that are confirmed and displayed is a big hit If it becomes a symbol (3-digit numbered symbol), it is a big hit, and as described above, a big hit game that opens the attacker as the big prize opening 7 in a predetermined manner (described as 16R big hit game in FIG. 38) And the other special symbol combinations are out of place (variation pattern 1, special symbol variation time T = 7 seconds). In addition, as described above, there is a detachment of reach of plus / minus 1 symbol and a detachment of reach other than plus / minus 1 symbol as described above. 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 actuating gate 19, and by this passage, the normal symbol display device 18 starts to display a one-digit normal symbol variation display (normal symbol variation time t = 30 seconds). While the normal symbol change display is displayed in a predetermined manner on the normal symbol display device 18, when one game ball passes through the normal symbol operation gate 19, the hold LED 26a is turned on. The hold LEDs 26b, 26c, and 26d are sequentially turned on each time one passes through the operation gate 19, and after that, even if the game ball passes through the normal symbol operation gate 19, it becomes an overflow ball and is not stored as a pass hold ball.

  When the normal symbol change display displayed on the normal symbol display device 18 is finished and a predetermined normal symbol is fixedly displayed, one corresponding hold LED 26 is turned off (the hold LEDs 26d, 26c, 26b, 26a are turned off). The normal symbol display device 18 starts to display the next normal symbol variation again. Thereafter, in the gaming machine 1, when the game ball passes through the normal symbol operation gate 19, 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 device 18 becomes a winning symbol (“7”), the winning symbol is “hit”, and the blade of the start winning opening (electric tulip) 11 is opened for a predetermined time as described above. The winning game is executed (start winning opening opening time ST = 0.2 seconds).

  Then, when the game related to the special symbol and the normal symbol is repeated in this manner, as shown in FIG. 38, the special symbol display symbol (big hit) is displayed on the image display unit 30 of the special symbol display device 6 as a result of the slot game. When the odd number of numbers in the symbol is displayed in a definite manner, the jackpot probability increases after the 16R jackpot game ends. In other words, the probability of a big hit increases from 1/315 to 5/315 by changing the contents of the big hit determination counter C1 (random numbers 1, 0 to 314). Therefore, when the big hit probability is increasing, the probability of winning a big hit is dramatically improved, that is, when the specific big win symbol is confirmed and displayed, the gaming state becomes extremely advantageous for the player.

  During the big hit game, a large number of game balls win the big prize opening 7 so that the player can obtain a large amount of prize balls, and also in the start prize opening 11 and the normal symbol operation gate 19. A large number of game balls have won or passed, and the maximum number of holding balls and passing holding balls is four (the holding LEDs 25a, 25b, 25c, 25d and the holding LEDs 26a, 26b, 26c, 26d are all lit). .

  Also, at the same time as the big hit game ends and the big hit probability rises, a lottery to stop the falling lottery and the falling lottery (hereinafter also referred to as a fall stop lottery) is started. The falling lottery is a lottery for determining whether or not the big hit probability falls from a high probability (5/315) to a low probability (1/315), and the falling stop lottery determines whether or not to stop the falling lottery. Both of them are executed each time in the slot game after the end of the big hit game. In normal times, the probability of falling lottery (falling probability) is set to 1/100, and the probability of falling stop lottery (falling lottery stop probability) is set to 1/50.

  Here, when three or more holding balls are stored (the holding LEDs 25a, 25b, 25c or the holding LEDs 25a, 25b, 25c, 25d are all lit), the falling lottery stop determining counter C9 (random numbers 9, 0-49). ) And the probability variation fall determination counter C10 (random numbers 10, 0 to 199) are respectively changed to raise the fall lottery stop probability from 1/50 to 1/25, while the fall probability is reduced from 1/100 to 1 / Reduce to 200.

  Furthermore, when there are three or more reserved memories, a fall probability reduction effect display is displayed on the image display unit 30 of the special symbol display device 6, and the fall lottery is stopped in the fall stop lottery in this slot game. And the fact that the probability that the jackpot probability falls from the high probability in the falling lottery is decreasing is displayed directly or indirectly. This drop probability reduction effect display is displayed by randomly selecting any one of the five types.

  Therefore, when the number of held memories becomes 3 or more due to a slot game (indicated as “start with increasing jackpot probability” in FIG. 38), the player has an increased probability of falling lottery. In addition, the player recognizes or predicts that the fall probability is reduced, and tries to make a lot of game balls to be awarded to the start winning opening 11 so as to constantly increase the holding memory to three or more. On the other hand, on the game hall side, so-called stop-stop is not performed while the player's jackpot probability is increasing, so the operating rate of the gaming machine 1 is improved and sales are increased. Note that the player can also recognize or predict that the jackpot probability has increased with a high probability by the fall probability reduction effect display.

  Here, when the number of starts (probability variation number) during the big hit probability increase is a multiple of 100 (in FIG. 38, described as every 100 starts after big hit), the image display unit 30 of the special symbol display device 6 displays Then, a high-probability suggesting effect display is displayed across a plurality of subsequent slot games, and an effect display that suggests that the jackpot probability is high is performed.

  This high-probability suggestion display is displayed by randomly selecting any one of the five types, and is displayed across a plurality of slot games of the high-probability suggestion display. The number of production continuations is selected and set from 3 to 7 based on the value of the production continuation count determination counter C10 (random numbers 10, 0 to 4). Further, the high probability suggesting effect display is displayed together with the falling probability lowering effect display when the above-described falling probability lowering effect display overlaps with the display time.

  Therefore, after the jackpot game is finished and the jackpot probability rises to 1/63 of the high probability, the player can play the jackpot game even after a slot game of multiples of 100 without playing the jackpot. Even when a long time has passed without a big hit since the end of the game, predict that the big hit probability is maintained at a high probability by high-probability suggestion display, and give up the game with expectation As a result, the interest of the game increases and the operating rate of the gaming machine 1 is improved.

  Referring to FIG. 38, if it is determined that the falling lottery is to be stopped as a result of the falling stop lottery during the start when the jackpot probability is rising (shown as falling lottery stop confirmed in FIG. 38), the falling lottery and the falling stop lottery are stopped. At the same time, a drop lottery stop effect display is displayed on the image display unit 30 of the special symbol display device 6, and the lottery for dropping the big hit probability from a high probability in the subsequent slot games (including the current slot game) is stopped. It is directly or indirectly displayed that the jackpot probability is guaranteed with a high probability and that the lottery that stops the lottery that falls from the high probability is stopped, that is, that the fall stop lottery stops. This falling lottery stop effect display is displayed by randomly selecting any one of the five types, and when the above high probability suggestion effect display and the display time overlap, the high probability suggestion is displayed. Displayed together with the production display. Therefore, the player recognizes or predicts that the falling lottery and the falling stop lottery will be stopped after the current slot game, that is, the big hit probability is guaranteed with a high probability, and expects great expectations. You can have a game, and your willingness to play will increase.

  Then, in the slot game during the period in which the falling lottery and the falling stop lottery are stopped (described as “falling lottery stop” in FIG. 38), this time, the plus / minus one symbol is out of reach (variation pattern 21, 31, 51 or 61). Is displayed, the falling lottery and the falling stop lottery are restarted from the next slot game, and the falling lottery start effect display is displayed on the image display unit 30 of the special symbol display device 6, and the big hit probability is increased from the next slot game. An effect display that suggests that the lottery that falls from the probability is restarted and that the lottery that stops the lottery that falls from the high probability is restarted, that is, the fall stop lottery is restarted is performed.

  This drop lottery start effect display is displayed by randomly selecting one of the five types, and when the above-described high probability suggestion effect display and the display time overlap, a high probability suggestion is displayed. Displayed together with the production display. Therefore, the player recognizes or predicts that the jackpot probability is maintained without falling from a high probability by the fall lottery start effect display, and the fall lottery and the fall stop lottery are resumed, and has great expectations. Along with being able to face the game, it is possible to make an appropriate judgment in continuing the game.

  Referring to FIG. 38, if it is determined that the jackpot probability is to be dropped from a high probability as a result of the falling lottery (described as “falling confirmed” in FIG. 38), the falling lottery and the falling stop lottery are finished, and the slots to be performed thereafter For games (including the current slot game), the content of the jackpot determination counter C1 (random numbers 1, 0 to 314) is changed to reduce the probability of winning a jackpot from 5/315 to 1/315. That is, this gaming state is the same as the normal gaming state before the big hit.

  Here, if the number of continuations of the above-mentioned high-probability suggestion effect display is in the middle of digestion when the big hit probability falls from the high probability, the high-probability suggestion display is stopped and the special symbol display device A discontinuation effect display is displayed on the image display unit 6 of 6 and an effect display suggesting that the jackpot probability has fallen from a high probability is performed. This discontinuation effect display is displayed by randomly selecting one of five types. Therefore, the player can predict that the jackpot probability has fallen from the high probability when the high probability suggestion effect display is switched to the discontinuation effect display, so the player can determine whether or not to continue the game. Can be done appropriately.

  The slot game is played in the normal gaming state before the big hit probability falls from the high probability and the gaming state becomes the big hit, and this gaming state is until the specific big winning symbol is confirmed and displayed next time. Maintained. Thus, when the specific big symbol is confirmed and displayed, the game will proceed in the same manner as described above.

  After the big hit probability falls from the high probability, the fact that the big hit probability has fallen from the high probability is displayed on the image display unit 30 of the special symbol display device 6 based on the establishment of a predetermined game condition. Then, it may be suggested to the player. In this way, the player can predict that the big hit probability has fallen from the high probability as in the case of the discontinuation effect display, and therefore can appropriately determine whether or not to continue the game.

  As described above, with reference to FIG. 38, the flow of the game from when the specific big win symbol is fixedly displayed and the jackpot probability rises to a high probability until it falls again to the normal probability has been explained. As the game progresses, the specific big symbol as a result of the slot game is displayed on the image display unit 30 of the special symbol display device 6 at any timing as shown in FIG. The game is continued as described above again after returning to the point of the specific big symbol symbol display. 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, the jackpot probability rises with probability fluctuations based on the specific big symbol being confirmed and displayed, and the jackpot probability has increased. In the gaming state, every time a 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. In addition to the falling lottery for determining whether or not the jackpot probability falls to a low probability, the lottery for determining whether or not to stop the falling lottery is performed every time the slot game is executed. When the fall lottery is stopped, the lottery lottery is not performed for a predetermined period, and the jackpot probability can be maintained at a high probability. Therefore, in such a case, the player can hit the jackpot in a short time or continuously. An opportunity to win.

  That is, the gaming machine 1 of the present embodiment has both a falling lottery and a lottery for stopping the falling lottery. Therefore, according to the gaming machine 1 having such a configuration, the conventional next big hit occurs. Or a prize per unit time with a relatively high jackpot probability in a normal gaming state compared to a gaming machine in which the jackpot probability is unconditionally maintained until a predetermined number of slot games are executed. While the number of balls is averaged, it is possible to play games with moderate euphoria, and as a result, improve the interest of the game and provide suitable gaming machines regardless of beginners or experts It becomes possible.

  In addition, when a lottery to stop the falling lottery and the falling lottery is being performed, the probability of the lottery to stop the falling lottery and the falling lottery is changed by the establishment of a predetermined gaming condition, so various gaming states are created In addition, when a process related to stop lottery, stop lottery to stop the fall lottery, processing related to probability variation, etc. occurs, a production image is displayed in a timely manner to notify the player to that effect. As a result, the game taste and performance are greatly improved.

  In addition to these effects, when the jackpot probability is high after the jackpot game ends, the effect image suggests to the player over a plurality of slot games that a predetermined game condition is established. When an image is displayed, and when the jackpot probability falls due to a falling lottery while the effect image is displayed, an effect image that suggests to that effect is also displayed. ing. Therefore, the player can obtain useful information for executing the game by using these effect images, and as a result, the current game state can be appropriately judged to predict future game development. It will be possible to further improve the playability.

  In addition, all the above-described effect displays are randomly performed by the display control circuit 111 by predetermined random number processing at the timing when the display control circuit 111 receives a display control command for instructing display of the predetermined effect image from the main control circuit 44. Since any one of the plurality of effect images is selected and displayed, the main control circuit 44 having a larger burden than the case where the main control circuit 44 executes an operation of selecting any one of the plurality of effect images. As a result, the load on the control circuit 44 can be reduced. As a result, a stable circuit configuration can be realized. In addition, the specifications of the central processing unit of the control circuit 44 can be reduced, and the storage capacity of the memory can be reduced. Cost can be reduced.

  In the gaming machine 1 according to the present embodiment, the means for dropping the big hit probability from the high probability is, as described above, the individual lottery ( This is performed by the probability variation fall determination counter C10), for example, when a predetermined special symbol combination (except for the jackpot symbol) or a predetermined normal symbol is confirmed and displayed while the jackpot probability is high, or Other lotteries (random numbers 1 to 9, 11, 12) may be used together, such as when a predetermined reach variation pattern or character appears, or a predetermined game condition is established instead of lottery. For example, it may be performed when a game ball wins a predetermined winning device.

  In addition, the probability of falling lottery or the probability of stopping lottery may be determined according to the type of the specific big win symbol. In this way, the player becomes very interested in the special symbol and is confirmed. The particular big symbol that is displayed is anxious and this further improves the gameplay. In addition, the probability of falling lottery or the lottery probability of stopping falling lottery may be determined by lottery separately by a predetermined random number process or the like. When the jackpot game related to the symbol is finished, the player may be notified directly or indirectly by an effect display or the like, particularly when the probability of the falling lottery is low or the lottery probability of stopping the falling lottery is low. This should be done when it is high.

  In addition, the probability of falling lottery and the lottery probability of stopping the falling lottery are reduced and increased when the number of reserved balls exceeds a predetermined number while the big hit probability is high, but either one may be fixed. Alternatively, the probability of the falling lottery may be decreased or / and the lottery probability of stopping the falling lottery may be increased in proportion to an increase in the number of reserved balls. Alternatively, the probability of falling lottery and / or the lottery probability of stopping falling lottery may be reduced or increased based on a predetermined symbol being displayed as a normal symbol. For example, “5 ”Is confirmed and displayed, and the probability of falling lottery and the lottery probability of dropping lottery stop are decreased and increased. Based on that“ 2 ”is confirmed and displayed, the probability of falling lottery and You may make it return a lottery probability to the original probability.

  Furthermore, as these modifications, the probability of falling lottery is decreased and / or the probability of falling lottery stop is increased according to an instruction regarding a predetermined game, for example, display on the image display unit 30 of the special symbol display device 6 It may be performed in accordance with an instruction to win a game ball to a predetermined winning device, an instruction to make a specific number of reserved balls, or the like notified by voice from the speaker 113, or a falling lottery and / or The lottery probability of stopping the falling lottery may be lowered or raised when a predetermined specific big symbol is continuously displayed as a big hit symbol.

  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.

  Further, as a modification, the falling lottery is performed in three stages, the first stage lottery probability is 1/5, the second stage lottery is 1/5, the third stage lottery probability is 1/5, When a lottery is won, the player may fall from a high probability to a low probability. In addition, it is preferable to make it possible to know approximately the state in which the user is staying by changing the color of the character, the background, or the like according to the staying state at each stage. Furthermore, it is preferable to provide a probability setting means capable of setting the lottery probability at each stage so as to differ according to an operation from outside the gaming machine 1. Thus, if the probability of falling lottery can be set differently according to the probability setting means of the gaming machine 1, the operating profit can be easily adjusted for the hall, and the player can execute the game several times. Accordingly, it is possible to roughly know that the setting is advantageous for the player, and technical intervention can be performed based on the knowledge.

  In addition, the lottery of the falling lottery and the falling lottery stop is canceled by displaying a predetermined fluctuation pattern on the image display unit 30 of the special symbol display device 6, but this displays a predetermined character. It may be executed when the number of slot games or the number of shot balls becomes a predetermined value after the lottery of the falling lottery and the falling lottery stop is stopped. When a stop release lottery based on a predetermined random number process (predetermined lottery probability) performed for each slot game due to winning a prize is won, it may be executed.

  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, and even if the big hit does not come for a long time as much as possible, it will rescue the player who continues the game persistently Because I want to. In addition, when the big hit probability returns to a high probability in this way, or when the specific big win symbol is confirmed and displayed and the big hit probability becomes high immediately after the end of the big hit game, the 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, the timing at which the jackpot probability falls to a low probability by the falling lottery is such that a random number (probability falling judgment counter C10) is acquired when the game ball is won at the start winning slot 11, and the game ball that has won the start winning slot 11 is obtained. The result of the falling lottery is reflected in the slot game corresponding to the (successful lottery), but this does not affect the slot game corresponding to the game ball won in the start winning slot 11, and the next time You may make it reflect the result of a falling lottery from a slot game. In this way, for the player, the number of slot games that are played with a high probability of winning is increased by one, and the game taste is improved. In order to realize this, in the special symbol game process shown in FIG. 18, the probability change fall process in step S331 may be executed after the process in step S345.

  In addition, the drop lottery start effect display, the high probability suggestion effect display, and the discontinuation effect display indicate the player to that effect, but the high probability suggestion effect display directly informs the player of that effect. It may be changed to a production display. This is because the content to be notified of the high-probability suggesting effect display is advantageous for the player, while the falling lottery start effect display and the discontinuation effect display are disadvantageous for the player. That is, it is not preferable to notify the player directly of contents that are disadvantageous to the player. It should be noted that not only these effect displays, but all the above-mentioned effect displays are dummy-displayed at a predetermined probability (preferably low probability) (the contents of the effect display and the game state are displayed). (Pseudo effect display in which an effect display is displayed at the timing of mismatch). 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, the following can be cited. In other words, even if the jackpot probability is high, in other words, the drop-off lottery causes a censoring effect display to appear even though the jackpot probability has not fallen from the high probability (in this case, the high-probability suggestion display is not always performed). After that, if this jackpot probability continues to be high for a predetermined period (for example, 30 slot games), the probability change return effect display is performed (in this case, as described above). This is a mode of waiting for a high-probability suggestion display to appear. Or, even though the big hit probability has fallen to a low probability, a high probability suggesting effect display appears (in this case, the predetermined variation pattern display may not necessarily be performed), This is an aspect that does not appear.

  In other words, in the former case, it is an effect display that makes it impossible for the player to know whether the jackpot probability is high or low as the gaming state, and in the latter case, the jackpot probability falls to a low probability. Despite being played, it is an effect display that makes it appear that the jackpot probability is high as a gaming state, and accordingly, by performing such dummy effect display as appropriate, the interest of the game further increases .

  Also, if the big hit probability falls from the high probability in the fall lottery while the high probability suggestion display is displayed, if the end effect display that suggests that is always displayed, the player will be disappointed and play the game. It may be possible to stop. Therefore, the discontinuation effect display is made to appear even when the jackpot probability has not fallen from a high probability with a predetermined probability. In this case, the content of the discontinuation effect display is preferably as follows. That is, the content of the discontinuation effect display is given a story, and the effect is such that the jackpot probability gradually falls from a high probability (in this case, it may straddle a plurality of slot games). The end of the story) should be performed in a scene that branches both when the result is good and when it is bad. If the discontinuation effect display has such contents, the player does not know whether the jackpot probability is high or low as the gaming state, so even if the discontinuation effect display appears, Stopping the game without being discouraged decreases, and as a result, the operating rate of the gaming machine 1 is improved.

  It should be noted that the high probability suggestion effect display is executed every time the number of slot games is a multiple of 100 regardless of whether the lottery is executed or stopped when the jackpot probability is high after the jackpot game ends. However, in this case, the number of slot games when the falling lottery is stopped may be excluded from the number of times the slot game causes the high-probability suggestion display to be executed. Alternatively, this high probability suggestion effect display may be executed when the number of slot games is a multiple of 100 on condition that the falling lottery is stopped. The reason for this is that when the falling lottery is stopped, the probability of a big hit falling from a high probability is reduced during the display of the high probability suggestion effect displayed across a plurality of slot games. This is because the appearance rate of an undesired discontinuation effect display decreases.

  Further, in the gaming machine 1 of the present embodiment, when the specific big win symbol is confirmed and displayed, the jackpot probability is increased with a high probability, but in addition to this, the specific big win symbol is confirmed and displayed. Until a predetermined number (for example, 100 times) of slot games is exhausted or until the next big hit comes, the content of the winning judgment counter C12 is changed to increase the chance of winning a normal symbol. (For example, 10/31 to 28/31), shorten the normal symbol fluctuation time t (for example, 30 seconds to 2 seconds), or extend the start winning opening opening time ST (for example, 0.2 seconds to 2 seconds) The special symbol variation 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.

  The jackpot probability, the falling probability, or the lottery probability of stopping the falling lottery are not limited to those described above, and may be set as appropriate within the scope of the present technical idea. The game contents of the jackpot processing may be game contents of the jackpot processing other than those described above as long as they do not deviate from this technical idea. For example, it may be a big hit game content that is adopted in so-called third type pachinko gaming machines. The special symbol display device 6 and the normal symbol display device 18 may be any device that can display symbols and numbers such as a liquid crystal display, a CRT display, a plasma display, and a dot matrix LED display.

  In addition, the symbol for generating the jackpot (the jackpot symbol) has been described using a predetermined three-digit symbol (special symbol). However, the jackpot symbol is not limited to three digits but may be any number of digits. . Moreover, although the above jackpot symbols have been described with the same symbol, they can be arbitrarily set, and any combination such as “ABC”, “Shochiku Ume” may be used as the jackpot symbol. In addition, the variation pattern corresponding to the out-of-reach symbol is only variation pattern 1, but a plurality of variation patterns may be provided.

  In addition, although the gaming machine 1 of the present embodiment has been described using the pachinko gaming machine that is one aspect of the embodiment, the gaming machine 1 is not limited to this. For example, in a gaming machine where a player operates a start lever, such as a throttle gaming machine, extracts a random number related to a hit or the like, and a spinning reel is driven based on the extracted random number value. The present invention can be employed.
