Abstract

<P>PROBLEM TO BE SOLVED: To provide a Pachinko game machine capable of enhancing player's reliability by stably and accurately performing a prediction notification for predicting winning generation in a probability variable state. <P>SOLUTION: When a winning stop symbol form is established, a first winning expectation value is generated on the basis of the remaining number of times of probability variation and the winning probability of the probability variable state. Further, when non-consumed special start storage data is a winning by the result of winning determination, a second winning expectation value is generated on the basis of the determination result. When there is the second winning expectation value, the prediction notification is performed according to it. When there is no second winning expectation value, the prediction notification is performed according to the first winning expectation value. Thus, since the accurate and stable prediction notification is performed by the first winning expectation value accurately indicating the possibility of the winning generation and the second winning expectation value indicating the presence/absence of the winning generation, the reliability of a player for the prediction notification is increased. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a pachinko gaming machine in which a winning or losing is determined according to a stop pattern aspect of a special symbol that fluctuates on a symbol display device, and a special game state in which a special winning opening is opened and closed in a predetermined manner in the case of winning.

  As a pachinko game machine, when a game ball is awarded to the start opening, special start memory data is generated and stored for determining a variation pattern of the special symbol and a stop symbol mode, and the special start memory data is digested. Thus, there is widely known a configuration in which a symbol generation process is executed in which a special symbol is changed and stopped, and the winning or losing is determined by the stopped symbol mode stopped in the symbol generation process. In this configuration, when the winning is determined by the symbol generation process, the game proceeds to a special game state in which the special winning opening is opened and closed in a predetermined manner. A configuration is known in which, after the end of the special gaming state, a process is performed in which the special start memory data is determined based on a high probability of winning.

  Here, since it is easy to generate a hit when a winning determination is made with a high probability of winning, if it becomes clear that a winning determination with a high probability of winning is performed after a special gaming state, The feeling of expecting a hit (so-called continuous change) increases. As a configuration that can stimulate such a player's emotion, for example, the configuration of Patent Document 1 has been proposed. In the configuration of Patent Document 1, when the special gaming state is entered, when there is undigested special start memory data, a hit or a loss is notified in advance based on the special start memory data.

JP 2004-154424 A

  In the configuration of the conventional Patent Document 1 described above, since the advance notice is performed based on the undigested special start storage data, the advance notice is performed when the undigested special start storage data does not exist. Absent. Further, when the start memory number of undigested special start memory data (hereinafter referred to as the undigested number) is less than a preset upper limit memory number, a notice is given only for undigested special start memory data. . Therefore, those who are familiar with the game can easily understand that the advance notice relates to undigested special start-up memory data, and it can be said that the effect of improving the preference is insufficient. Furthermore, this notice only determines whether the undigested special start-up memory data is a hit or a loss, and notifies the determination result deterministically or non-deterministically. Loss is completely known to the player, and hitting or losing is difficult to understand in a non-deterministic notice, and the notice itself may be unclear. Furthermore, even if a definitive notice and a non-determinable notice are mixed, the ambiguity of the notice cannot be resolved even though the tendency to be a hit or a loss can be reported to some extent. For this reason, there is a concern that it may promote a player's distrust of the notice.

  The present invention proposes a pachinko gaming machine that can stably and accurately predict the occurrence of a hit in a probability variation state to which a high probability of winning is applied, and can increase the player's confidence.

  The present invention relates to a symbol display device that displays a special symbol in a variable manner, a start opening provided with a ball detecting means for detecting a winning of a game ball, and a ball detecting means for the start opening that detects a game ball. The special start memory data for determining the variation mode and the stop symbol mode is generated and stored up to a preset upper limit memory number, and the special start memory data is sequentially digested to thereby generate the special start memory data. A symbol control means for executing a series of symbol generation processes to stop in a stop symbol mode in which a special symbol is changed on the symbol display device based on the stored data and the winning or losing is determined, and the symbol stop symbol pattern by the symbol generation process Once confirmed, in a pachinko gaming machine comprising a game control means for shifting to a special game state that opens and closes a special winning opening in a predetermined manner, when the game control means is in a special game state, In the pattern generation process, the winning probability of confirming the winning stop symbol pattern is assumed to be a probable change state, and the winning probability is not improved by reaching the predetermined upper limit probable number of times when the number of times of the symbol generation process executed in the probability change state is determined to be lost. If it is converted to a probability state and it is in a probable variation state, and the symbol pattern to be stopped is confirmed in the symbol generation process, the remaining residue is obtained by sequentially digesting the upper limit probability variation number with the execution of the symbol generation process. When there is a first winning expected value generating means for generating a first winning expected value generated in accordance with the probability variation number and the winning probability of the probability varying state, and undigested special start memory data Then, the hit determination of the special start memory data is performed, and if it is a hit, there is a second winning expected value generating means for generating a second winning expected value according to the determination result, and a second winning expected value. Foreseeing notification means for foreseeing foreseeing the occurrence of a hit in the probability variation state according to the second winning expectation value in the case, and in the case where the second winning expectation value does not exist according to the first winning expectation value. This is a pachinko machine characterized by

  Here, in the probability variation state, the winning determination is performed by applying the special start memory data by applying a high probability of winning, and in the normal probability state, the winning determination is performed by applying a winning probability having a normal probability lower than the high probability. In other words, the probability variation state and the normal probability state are distinguished depending on whether a high probability or a normal probability is applied to the winning probability. Therefore, the special game state that opens and closes the grand prize opening is a different concept from the normal game state that does not open and close the big prize opening, and each gaming state overlaps with the probability variation state and the normal probability state. possible). Then, the probability change state of one time starts when the winning symbol pattern is determined in the symbol generation process, and the number of times of execution of the symbol generation process to which the winning probability is applied reaches the upper limit probability variable number of times, or The process is terminated when the winning stop design is confirmed. Therefore, when the symbol generation process hits in the probability variation state and the stop symbol pattern is determined, the process proceeds to the next probability variation state, and the number of executions of the symbol generation process in the previous probability variation state is reset.

  In such a configuration, the first winning expectation value is generated based on the remaining probability variation number of the upper limit probability variation number and the winning probability of the probability variation state, and the prediction notification is performed according to the first winning expectation value. Even if there is no undigested special start memorized data or the number of undigested special start memorized data is less than the number of remaining probable changes, all symbols executed in the probable state by the first winning expected value Foreseeing notification for predicting the occurrence of a hit in the generation process may be performed. Furthermore, when it is determined that the undigested special start-up memory data is a hit, the second winning expected value according to the determination result is given priority over the first winning expected value, and foreseeing notification according to the second winning expected value, Foreseeing notification for predicting occurrence of hitting can be performed. In the configuration of the present invention, the foreseeing notification based on the winning probability of the probability variation state and the foreseeing notification based on the hit determination of the undigested special start memory data are appropriately performed, so that the foreseeing notification becomes stable and accurate contents. , It is possible to improve the player's confidence in the foreseeing notification. That is, in the configuration of the above-described conventional Patent Document 1, since the confirmation is made only by the determination of only the undigested special start stored data, the reliability of the notice is impaired. In the configuration of the present invention, as described above, it is possible to ensure the player's sense of trust in order to perform highly accurate prediction notification.

  This configuration also has an excellent advantage that the above-described effects can be obtained even when the upper limit probability variation number is set to be greater than the upper limit storage number. In the configuration of the conventional Patent Document 1 described above, since the difference between the upper limit probability variation number and the undigested special start storage data is likely to increase as the upper limit probability variation number increases, an object that cannot be notified in advance (unoccurrence of start memory). Will increase. In contrast, the configuration of the present invention generates the first winning expectation value based on the remaining probability variation number, so that the same reliability can be maintained even if the upper limit probability variation number is large.

  Note that the prediction notification can be displayed on a symbol display device or can be notified by symbol display, an acoustic mode, a light emission mode, or the like by providing a prediction notification device. Here, in the case of foreseeing with a symbol display device such as a symbol display device, it may be performed by displaying a symbol that numerically expresses the first winning expected value or the second winning expected value. It is also possible to set in advance a plurality of foreseeable symbols that show the ease of hitting in a stepwise manner, and select and display the foreseeable symbols according to each winning expectation value. Further, the foreseeing notification may be continued only for a predetermined time, or may be continued in a certain change state. On the other hand, the second winning expectation value may be a target for judging only the symbol generation process executed in the probability variation state, similarly to the first winning expectation value, or based on the winning probability even in the normal probability state. A hit determination may be made. That is, in the former configuration, the prediction notification is performed only in the probability variation state, but in the latter configuration, the prediction notification according to the second winning expected value may be performed even in a state other than the probability variation state.

  In addition, the probability change state is started when the special game state is entered (in response to the determination of the stop symbol pattern in the symbol generation process), and may be started together with the start of the special game state or the special game state. It may be started after the end of. In any case, since the winning symbol pattern is determined in order to enter the special game state that is the trigger for starting the probability variation state, the first winning expected value is generated using the determination as a trigger. Even when the probability change state is started together with the start of the special game state, the special start memory data is not digested in the special game state, so that the participation in the game is substantially after the special game state.

  In the pachinko gaming machine described above, the first winning expectation value generating means generates the first winning expectation value based on the remaining number of probable changes every time the special start memory data is digested in the probability changing state, and the second winning expectation expectation The value generation means performs a hit determination every time the special start stored data is generated, and if it is a win, the value generation means generates a second winning expected value according to the determination result. As the second winning expected value is generated, a configuration is proposed in which a prediction notification is performed. Here, it is preferable that the foreseeing / notifying means performs the foreseeing / notification according to the new winning expected value every time the first winning expected value or / and the second winning expected value is newly generated. In this case, if the newly generated winning expected value does not change from the previous winning expected value, the previous foreseeing notification may be maintained, or the foreseeing informing may be repeatedly performed.

  In such a configuration, every time the special start memory data is digested or the special start memory data is generated in the probability variation state, the first winning expected value and the second winning expected value are generated. Each winning expected value with high accuracy can be generated according to the game progress. Therefore, according to the progress of the game, high-precision and highly stable prediction notification can be performed, and the player's reliability can be further enhanced.

  As described above, the pachinko gaming machine of the present invention is in a probability variation state that starts when the special gaming state is entered, and when the winning stop pattern mode is determined, it is based on the remaining probability variation number and the winning probability of the probability variation state. The first winning expected value is generated, and if the undigested special start memory data is a hit based on the result of the hit determination, the second winning expected value is generated based on the determination result. If there is a forecast notification according to this, and if the second winning expected value does not exist, the forecast notification is performed according to the first winning expected value. Foreseeing notifications foreseeing the occurrence of hits in all symbol generation processes to be performed can be performed, and foreseeing notifications for predicting the occurrence of undigested special start-up memory data can be performed according to the second winning expected value. That. Thereby, since it is possible to perform stable and accurate prediction notification, it is possible to increase the player's confidence in the prediction notification. And, by obtaining the player's confidence, the interest of the game can be improved.

  In the pachinko gaming machine described above, each time the special start memory data is digested in the probability variation state, the first winning expected value is generated, and every time the special start memory data is generated, a hit determination is made, In the case of the configuration in which the second winning expected value is generated according to the determination result and the foreseeing notification is performed according to these, the progress of the game every time the special start memory data is digested or the special start memory data is generated in the probability variation Therefore, it is possible to perform the prediction notification with high accuracy according to the above, so that it is possible to further increase the player's reliability and to further enhance the interest of the game.

As shown in FIG. 1, the pachinko gaming machine 1 includes an outer frame 2 fixed to a game island facility (not shown) and a gaming machine main body 3 that covers a front opening of the outer frame 2. The gaming machine main body 3 includes a front frame 5 in which a game board 10 (see FIG. 2) is attached to a substantially circular opening at the upper center, and one side edge of the front frame 5 is connected to the outer frame via the hinge member 4. It is pivotally attached to 2 so that it can be opened and closed. Further, the front frame 5 is provided with a glass plate 6 that covers the game board 10. In addition, an upper tray 7 and a lower tray 8 are vertically arranged at the lower portion of the front frame 5, and a launching handle 9 is projected on the right side of the lower tray 8.

  The gaming machine body 3 is provided with a launching device (not shown) that launches a game ball so as to be concealed by the front frame 5. The launching device is configured to supply the game balls stored in the upper tray 7 one by one. Here, the upper receiving tray 7 has a ball payout opening 15 through which a prize ball or a rental ball flows out on the left side, and an alignment portion (not shown) for aligning game balls is formed in the right side. A ball inlet (not shown) for supplying a game ball to the launching device is opened at the right end of the unit.

  FIG. 2 is a front view of the game board 10 described above. A substantially circular game area 12 is defined by a guide rail 11 on the front surface of the game board 10, and a center case 13 incorporating various game members is disposed in the center of the game area 12. A game ball launched by the above-described launching device (not shown) rolls down in the game area 12.

  The center case 13 is assembled with a symbol display device 14 composed of a liquid crystal display. Various effect images and special symbols A, B, C, etc. are displayed on the screen of the symbol display device 14. Here, the special symbols A, B, and C are hit by a stop symbol mode comprising a combination of each special symbol that starts to change when a game ball flows into a starting port 22 of the variable prize winning device 21 to be described later and then stops. Confirm the loss. From the start of the variation of the special symbols A, B, and C to the stop symbol mode being determined is the symbol generation process according to the present invention. When the winning stop symbol mode is confirmed and stopped, a special game state in which a special prize opening 26, which will be described later, is opened and closed a predetermined number of times is entered, and a lot of prize balls are paid out by winning a game ball to the special prize opening 26. Since this special game state is an opportunity to obtain a large amount of prize balls, the special symbol A, B, C winning stop pattern mode that triggers the transition to the special game state is most desired by the player. The game ball is fired by the player aiming for a winning at the start port 22 that triggers the variation of the special symbols A, B, and C. In the special game state, the above-described symbol generation process is not executed, and the symbol generation process is executed in the normal game state. Then, when the above-mentioned winning stop pattern mode is determined in the normal game state, the game state is shifted to the special game state, and when the opening / closing operation of the special winning opening 26 is completed, the game state is shifted to the normal game state.

  Under the center case 13, a special start memory number display device 17 and a normal start memory number display device 18 each comprising four LEDs are provided. The special start memory number display device 17 is a start memory number of special start memory data generated every time the game ball flows into the start port 22 when game balls continuously flow into the start port 22 of the variable prize winning device 21 described later. (Hereinafter referred to as the undigested number) is displayed by the number of lighting of the LED. Further, the normal start memory number display device 18 displays the start memory number of normal start memory data that fluctuates a normal symbol (not shown), which will be described later, by the number of lighting of the LED. Here, the start memory numbers of the special start memory data and the normal start memory data are respectively set to four as the upper limit memory numbers (see FIG. 5).

  Normal symbol start gates (normal symbol start regions) 19 and 19 are disposed on the left and right sides of the center case 13, and the normal symbol start provided on each normal symbol start gate 19 by the passing of the game ball. When a game ball detection signal is generated from the switch S2 (see FIG. 3), a normal symbol (not shown) fluctuates on the display screen of the symbol display device 14, and stops after a predetermined time and various symbol patterns are displayed. Is done.

  Also, below the center case 13, a variable winning device 21 having a start port 22 through which game balls can flow and a pair of left and right opening / closing wing pieces (not shown) is disposed. A special symbol start switch S1 (see FIG. 3) for detecting a game ball is arranged inside the start port 22. According to the detection of the game ball by the special symbol start switch S1, the symbol display is performed as described above. The special symbols A, B, C are started to change on the screen of the device 14. That is, the special symbol start switch S1 constitutes the ball detecting means of the present invention. Also, the pair of left and right open / close wing pieces are raised in a vertical direction so that a single game ball can be won from above, and the game ball is expanded in an inverted C shape from both sides to the left and right sides. It is converted and driven to a tilting position that makes it easy to win. When the display result of the normal symbol (not shown) is a predetermined hit symbol, the opening / closing blade piece tilts for a predetermined time (about 0.2 seconds) with the normal electric accessory solenoid (not shown) as the drive source. The game ball is easily expanded into the start port 22 by being expanded to the position.

  Further, a special electric accessory 25 having a large winning opening 26 is disposed below the variable winning device 21. This special electric accessory 25 has a horizontally long rectangular opening / closing piece 27, and the opening / closing piece 27 is controlled to be opened / closed by a built-in large prize opening solenoid (not shown), whereby the special winning opening 26 is opened or closed. Converted to a state. When the special symbols A, B, and C that are variably displayed on the screen of the symbol display device 14 are fixedly displayed in a predetermined hit stop pattern mode (in the case of a big win), the special electric accessory 25 is a big prize opening. 26 is opened and closed. As the opening / closing operation of the special winning opening 26, the opening / closing piece 27 tilts forward and opens, and in the opened state, the game ball is guided into the special winning opening 26 through the guiding action of the upper surface of the opening / closing piece 27. An open / close round in which the open / close piece 27 is raised and the special winning opening 26 is closed by expiration of a predetermined opening time (for example, 30 seconds) or winning of a predetermined number (for example, 9) of game balls during the predetermined opening time. By performing the predetermined limit number of times (15 times in this embodiment), a large amount of game balls are won in the special winning opening 26, and a predetermined profit is provided to the player. A count switch S3 (see FIG. 3) for detecting a winning game ball is provided inside the special electric accessory 25. As described above, when the special symbols A, B, and C are fixedly displayed in a predetermined hit stop symbol form, the special game state in which the special electric accessory 25 is operated is shifted to. And this special game state is complete | finished when the opening / closing round which opens and closes the special winning opening 26 reaches the predetermined limit number of times (15 times).

  In addition, the game area 12 is provided with a plurality of general winning ports 58, and a predetermined number of prizes are awarded in accordance with the winning detection of the game ball by the general winning switch S4 (see FIG. 3) provided therein. The ball is paid out.

Next, the control circuit of the pachinko gaming machine 1 described above will be described with reference to the block diagram shown in FIG.
The control circuit includes a main control board 80, a payout control board 81, an effect control board 82, a power supply board 83, and a launch control board 84. The main control board 80 is constituted by a microcomputer and controls the game of the pachinko gaming machine 1 in an integrated manner. Various switches such as the special symbol start switch S1, the normal symbol start switch S2, and the count switch S3 and various sensors are connected to the main control board 80 via a panel surface relay terminal plate 90.

  The main control board 80 includes a central control unit CPU that executes arithmetic processing according to input signals from various switches and sensors and outputs predetermined command signals, a storage device ROM that stores control programs used for arithmetic processing, and the like. A storage device RAM that can read and write various data at any time is connected via an address bus (not shown) that unilaterally transmits information for designating an address for reading and writing data, and a data bus (not shown) that exchanges data Thus, a substrate circuit of the main control board 80 is configured.

Here, each random number value extracted from each random number table will be described in detail.
The jackpot random number table is composed of values in the range of 0 to 299, and when the special symbol start switch S1 is turned on, the jackpot random number value is extracted from the range (winning detection process described later). The extracted jackpot random number value is compared with a predetermined winning value, and if the extracted jackpot random number value matches the winning value, it is judged as “winning (special symbol winning)” and is not matched. In this case, it is judged “lost” (special symbol processing described later). Here, as the winning value, three numbers that are valid at the normal probability (for example, “7, 127, 227”) are set, and thirty numbers that are valid at the high probability are set. (For example, “7, 17, 27,...)”. Then, in the normal probability state described later, the winning value at the normal probability is valid and the above jackpot random value is determined, and in the probability variation state to be described later, the winning value at the high probability is enabled and the jackpot random value is determined. To do. In the normal probability state, the probability of hit determination (hereinafter referred to as winning probability) is 1/100, and in the probability variation state, the winning probability is 1/10.

  In the case of the present embodiment, the probability variation state starts when the conversion condition to the probability variation state is satisfied, and ends when the termination condition of the probability variation state is satisfied. The condition for conversion to the probability change state is that the special symbols A, B, C are hit and the stop symbol mode is confirmed and displayed (special game flag = 1) (special symbol processing described later). On the other hand, the end condition of the probability variation state is that the number of times that the special symbols A, B, and C are fixedly displayed in the lost stop symbol mode (the number of times the symbol generation process is executed) reaches the upper limit probability variation number (probability variation flag = 0). One condition. Further, as the end condition, the second condition is that it becomes clear that the next stop symbol pattern is confirmed and displayed (probability change flag = 0). That is, the probability variation state is started when the winning stop symbol pattern is confirmed and displayed, and is terminated when the number of stops of the loss stop symbol pattern reaches the upper limit certain variation number after the next time or when the winning symbol pattern is confirmed and displayed next time. When the probability variation state ends, the normal probability state is converted. It should be noted that, with the end of the probability changing state, the number of stoppages of the lost stop pattern mode (the number of times the symbol generating process is executed) counted in the probability changing state is reset.

Special start storage data is generated and stored in the storage device RAM (winning detection process). The special start memory data is stored according to the generation order, and the start memory number (undigested number) is notified by the number of lighting of the special start memory number display device 17 described above. Then, a series of symbol generation processes from the start of variation of the special symbol to the fixed stop according to each random number value constituting the special startup memory data is digested in order from the special startup memory data stored first. Display is executed by the symbol display device 14 (special symbol processing described later).

Next, the control mode by the control circuit shown in FIG. 3 will be described according to the operation of the pachinko gaming machine 1.
When the above-described launch handle 9 is operated by the player, the game ball is launched into the game area 12. When the game ball passes through the normal symbol start gate 19 and the normal symbol start switch S2 is turned ON, the main control board 80 selects a normal random number value by a winning detection process (see FIG. 4). Then, a process (not shown) for determining the normal random number is performed, and a normal symbol process (not shown) for changing the normal symbol (not shown) is performed on the symbol display device 14 by the effect control board 82. In accordance with the selected normal random number value (normal start storage data), the normal symbol is fixed and stopped. Here, when a normal symbol hits and stops in a fixed pattern mode, control is performed to expand the opening / closing blade piece (not shown) of the variable winning device 21 to the tilting position by the normal electric accessory processing (not shown). Do.

  When the game ball rolling down the game area 12 flows into the start port 22 of the variable winning device 21, the special symbol start switch S1 is turned ON by the winning detection process of FIG. 4, and an input signal by this ON operation is received. The main control board 80 performs processing for extracting the random number values described above and storing the special start storage data. Here, the central control unit CPU of the main control board 80 is a jackpot random number table, a jackpot symbol random number table, a lose symbol random number table, a reach symbol random number table, a reach symbol random number table, a variation mode random number table, etc. stored in the storage device ROM. A lottery is used to extract a jackpot special random number value, a jackpot symbol random number value, etc., and each random number value is temporarily stored in the storage device RAM as a set of special start storage data.

  When the game ball continuously flows into the start port 22, each time the special symbol start switch S1 is turned ON, the random number value is selected as described above and the special start storage data is sequentially generated. The data is sequentially stored in the storage device RAM, and the light emitting diodes of the special start memory number display device 17 are sequentially turned on according to the number of undigested (start memory number). Since the number of undigested special start stored data is set to a maximum of 4 (upper limit stored number), a new start to the start port 22 in a state where 4 unstarted special start stored data are stored. Even if a game ball flows in, no special start memory data is generated.

  When the main control board 80 stores the special start memory data in the storage device RAM, the main control board 80 digests the special start memory data in the order of occurrence and performs special stop processing for controlling the variable symbols A, B, and C to be stopped. (See FIG. 5). That is, one special start storage data is read, a big hit random number value of the special start storage data is determined, a command signal is transmitted to the effect control board 82, and the special start memory number display device 17 is transmitted by the effect control board 82. One light emitting diode is turned off, and the symbol variation of special symbols A, B, and C is started. Here, when the probability variation flag = 1 (in the case of the probability variation state), the winning value with a high probability is validated to determine the big hit random number value. When the probability variation flag = 0 (in the normal probability state), the normal The jackpot random number value is determined by validating the winning value of the probability. When it is determined that the jackpot random number value is a win by this determination, the jackpot symbol random number value is selected to determine the hit stop symbol mode, and further, the symbol display device according to the other random number value by the special symbol fluctuation stop mode selection process The winning symbol variation pattern displayed at 14 is selected. In the special symbol variation stop mode selection process, not only the variation patterns of the special symbols A, B, and C but also the effect symbol pattern to be displayed during the variation is selected. Then, a variation time measurement timer is set, and the winning symbol variation pattern and effect symbol pattern selected in the special symbol variation stop mode selection process are set. In this way, the process of reading the (undigested) special start-up memory data stored in the storage device RAM and selecting the variation pattern according to the random number values, digests the so-called undigested special symbol start-up memory. It is processing to do. Accordingly, the symbol display device 14 displays a series of symbol generation processes until the special symbols A, B, and C are hit and fixedly stopped in the stopped symbol form. On the other hand, when the jackpot random number value is determined to be lost, the lost symbol random number value is selected to determine the loss stop symbol pattern, and the loss symbol variation pattern is selected according to the other random number values. A series of symbol generation processes until the special symbols A, B, and C are fixedly stopped in a lost stop pattern mode are displayed.

  As described above, when the winning stop symbol mode is confirmed and displayed by the symbol generation process, the big prize opening process (see FIG. 6) for controlling the opening / closing operation of the big prize opening 26 is performed. As described above, the open / close round for opening and closing the large winning opening 26 is performed a predetermined number of times (15 times) by this large winning opening process, and the game ball that has won the large winning opening 26 by the above winning detection process is counted by the count switch S3. Each time it detects, a process of paying out a predetermined number of prize balls is performed. Since this special game operation can acquire a lot of prize balls in a relatively short time, the profit provided to the player is also high, and it is one of the game states most desired by the player. The state where the open / close round of the special winning opening 26 is executed by this special winning opening process is the special gaming state of the present invention. This special game state starts when the winning stop symbol mode is determined (special game flag = 1) and ends when a predetermined number of open / close rounds are completed (special game flag = 0). It should be noted that a state other than the special game state is a normal game state in this embodiment.

  In the present embodiment, the special symbols A, B, and C are composed of numbers “0” to “9”, respectively. Other than that is lost. That is, the special symbol A = B = C is a hit stop symbol mode, and the other symbols are lost stop symbol modes.

  In addition, as described above, the special start memory data is stored up to four, and is processed in the order in which it is generated to execute the symbol generation process, so that the special start before digestion (undigested) is performed. The stored data is stored and maintained.

  When a game ball wins the start opening 22, the big winning opening 26, and the general winning opening 58, a payout process for paying out a predetermined number of winning balls is performed by a winning detection process (see FIG. 5). In this payout process, the above payout device (not shown) is driven and controlled so as to pay out the respective number of prize balls according to the ball detection of each switch S1, S3, S4.

  In the present embodiment, as described above, the process of digesting the special symbol start memory has been mainly described. However, other processes (for example, the main process) can be executed in the same manner as the conventional configuration. Details thereof are omitted as appropriate.

  Incidentally, the special symbol start switch S1 disposed in the start port 22 described above constitutes the ball detecting means according to the present invention. Further, the start memory generating means according to the present invention is constituted by the main control board 80 for executing the above-described winning detection process. Further, the symbol control means according to the present invention is constituted by a main control board 80 and an effect control board 82 for executing the above-described special symbol processing. In addition, the game control means according to the present invention is constituted by a payout control base 81 for executing the above-described special winning a prize opening process and a main control base 80 for executing a special symbol process.

Next, the main part of the present invention will be described.
In the probability variation state and the normal probability state described above, the winning probabilities for determining the jackpot random number value of the special start stored data are different. Specifically, as described above, the winning probability is 1/100 in the normal probability state, whereas the winning probability is 1/10 in the probability variation state. It can be said that it is an advantageous state that it is easy to hit 10 times.

  This probability change state starts when the special game flag = 1 in the special symbol process of FIG. 5 and ends when the probability change flag = 0. That is, the special game flag = 1 is the start condition (conversion condition) of the probability change state, and the probability change flag = 0 is the end condition of the probability change state. The probability changing state starts by determining the winning symbol pattern in the symbol generation process, continues during the special gaming state, and then reaches the normal gaming state thereafter. Then, in this normal gaming state, either the case where it is determined that the big hit random number value is the next, or the case where the number of executions of the symbol generation process for determining the loss stop symbol form has reached the upper limit probability variation number (four times) As a result, the probability variation state ends. Here, in the probability variation state (probability variation flag = 1), when the symbol generation process continuously determines the loss stop symbol pattern, and the number of times the loss is confirmed (the number of executions) becomes the upper limit probability variation number, the probability variation flag = 0 is normally set. Convert to a probability state. Further, if it is determined that the winning is determined by digesting the special start stored data before reaching the upper limit probability changing number in the probability changing state (big hit flag = 1), the probability changing flag = 0 is set. In the latter case, a new probability change state is established by determining the winning stop symbol pattern in the symbol generating process based on the special start stored data determined to be a hit. In this embodiment, the upper limit probability variation number is set to four, which is the same as the upper limit storage number.

  Here, in the present embodiment, in the state of probability variation flag = 1 (probability variation state), the variation time in the symbol generation process is shortened compared to the normal probability state. Furthermore, the winning probability of the above-mentioned normal symbol is set to a high probability and the fluctuation time of the normal symbol is shortened, and the time for the variable winning device 21 to be expanded is also longer than the normal probability state. . For this reason, in the probability variation state, it is easy to win the starting port 22 and the winning probability is high, so that the winning process is confirmed in the symbol generation process of the special symbols A, B, and C compared to the normal probability state. It is easy for the player to obtain profits.

  Then, the state in which the probability variation flag = 1 is started by the end of the special game state. That is, when a predetermined number of open / close rounds are completed in the special gaming state, the special gaming state is terminated and the normal gaming state is entered, and the normal gaming state and the probability variation flag = 1 are set as described above. The player can easily obtain profits. As described above, in this embodiment, when the special game state is entered, after the completion of the special game state, it becomes a state in which a hit is likely to occur until at least four times (upper limit variation number of times) the symbol generation process is completed. In the special game state, since the process for digesting the special start memory data is not performed (the symbol generation process is not executed), the benefits such as shortening the variation time of the special symbols A, B, and C described above do not occur.

  On the other hand, in the pachinko gaming machine 1 configured as described above, when the winning symbol pattern is determined by the symbol generating process, the prediction notification for predicting the occurrence of the winning is performed in the above-described probability variation state. Here, as the prediction notification, predetermined prediction symbol forms a to e are displayed on the symbol display device 14 so as to notify the player of the possibility of hitting. In the present embodiment, five kinds of foreseeable design aspects a to e are set in advance, and the foreseeable design aspect a to foreseeable design aspect e are set in descending order of possibility of occurrence. That is, when the foreseeable design aspect a is expressed, it is most likely to occur in the state of probability change, and when the foreseeable design aspect e is expressed, the possibility of occurrence in the state of probability change is the lowest. And according to the 1st winning expected value or the 2nd winning expected value mentioned later, foreseeable design aspect ae is selected and displayed on the symbol display apparatus 14 (refer FIG. 9).

  The first winning expected value for selecting the foreseeable design aspects a to e is generated by the first winning expected value generating process of FIG. As the first winning expected value generation process, when the winning symbol pattern is determined in the symbol generation process (when the special game flag = 1), the remaining probability variation number assigned the upper limit probability variation number and the probability variation probability probability ( And a calculation process for calculating the first winning expected value. Here, in the special symbol process of FIG. 5, when the winning / stopping symbol mode is determined, the special game flag = 1 and the probability change state is set, and the calculation flag = 0 is set. Since the symbol generation process is not executed in the special gaming state, the first winning expectation value is maintained until the special gaming state is ended by setting calculation flag = 1 (see FIG. 9).

  When the special game state ends, as described above, the symbol generation process is executed by sequentially digesting the special start storage data. As shown in FIG. 5, every time the loss stop symbol form is determined by this symbol generation process, the number of symbol generation processes executed in the probability variation state decreases, and the decrease flag = 1, and the first winning expectation in FIG. The remaining number of remaining probability changes is calculated by the value generation process. Here, the remaining probability variation number is the number of times of the symbol generation process that can be executed in the probability variation state, which is left by sequentially digesting the upper limit probability variation number with the execution of the symbol generation process. As the remaining probability variation number decreases, the first winning expectation value calculated by applying the residual probability variation number also changes. Therefore, after the end of the special gaming state, every time the symbol generation process determines the loss stop symbol aspect in the probability variation state, the remaining probability variation number and the winning probability of the probability variation state are applied, and the calculation process described above The winning expectation value is calculated.

Here, in the calculation process of the present embodiment, the first winning expectation value is calculated by the following equation (1) by applying the remaining probability variation number and the winning probability (= 1/10) of the probability variation state. The following formula (1) is a formula for calculating, as the first winning expected value, the probability (%) that at least one hit occurs in the symbol generation process of the remaining probability variation number. That is, since the probability of losing in the probability state is 9/10 (= 1−1 / 10), if the residual probability variation number is N, N times by removing the probability of losing all N times. The probability that at least one hit will occur can be obtained.
Expected first winning value (%) = {1− (9/10) ^N } × 100 Expression (1)
Specifically, when the number N of residual probability changes is 4, the expected value of the first winning is about 34%, about 27% when N = 3, and about 20% when N = 2. , N = one time is calculated as about 10%.

  Further, the second winning expected value for selecting the foreseeable design aspects a to e is generated by the second winning expected value generating process of FIG. 8 executed after the first winning expected value generating process. As the second winning expected value generation process, when the hit symbol pattern is determined in the symbol generation process (when the special game flag = 1), the undigested special start is found when there is undigested special start memory data. Each big hit random number value of the stored data is determined based on a winning probability (high probability) in the probability variation state, and if it is determined to be a win, a generation process for generating a second winning expected value is performed. Here, when the winning stop symbol mode is determined, the calculation flag = 0 is set as described above (see FIG. 5) to generate the second winning expected value at this point. In addition, when there is no undigested special start memory data, the second winning expected value generation process is terminated, and when all the big hit random numbers of undigested special start memory data are determined to be lost, The second winning expected value generation process is terminated without executing the process.

  This second winning expectation value generation process is performed every time new undigested special start memory data is generated even if it is in a special game state, and the jackpot random number value of the special start memory data is determined as the winning probability of the probability change game state. Judgment by Then, in the case of winning, the second winning expected value is generated by the generation process, and in the case of losing, the generation process is terminated without executing. Even in the probability change state (probability change flag = 1) after the end of the special game state, the second winning expected value generation process is performed in the same manner as described above each time new undigested special start storage data is generated.

  In the second winning expected value generation process of this embodiment, when the big winning random number value of the undigested special start storage data is determined to be a hit and the second winning expected value is generated, the second winning flag = 1 is set. Thereafter, the process for determining the hitting of the undigested special start-up memory data is not performed. This is because the undigested special start-up memory data determined to be a hit is digested in the probability change state and the hit determination is performed, so that the probability change flag = 0 and the probability change state ends.

  Furthermore, in the second winning expected value generation process, every time the loss stop symbol pattern is determined by the symbol generating process in the probability variation state (decrease flag = 1 in FIG. 5), the above generation process is performed, and the second winning expected value is determined. Is generated. This is because the generation process of the present embodiment obtains the second winning expected value based on the remaining probability variation number, as will be described later.

Here, in the generation process of the present embodiment, when there is undigested special start memory data that has been determined that the big hit random number value is a win, the remaining certain variation number determined by the first winning expected value generation process is used, and the second Generate winning expectation value. Specifically, the second winning expectation value is obtained by the following equation (2) on the assumption that it occurs at least once in N times of the remaining probability variation number. In the present embodiment, correction is made to reduce the numerical difference from the above first winning expected value by multiplying by 0.8.
Expected second winning value (%) = (1 / N) × 100 × 0.8 Expression (2)
In this equation (2), the second winning expectation value changes each time the remaining probability variation number N decreases. As described above, every time the loss stop symbol pattern is determined by the symbol generation process in the probability variation state (decrease flag) = 1), the second winning expected value is generated by the generation process. The second winning expectation value is 20% if the number N of residual probability changes is 4 when the undigested special start memory data is determined to be a hit, about 27% if N = 3, N = If it is twice, 40%, N = 80% if it is once.

  After the first winning expected value generation process and the second winning expected value generation process described above, a prediction notification process for displaying the prediction symbol forms a to e on the symbol display device 14 is performed as shown in FIG. In this foreseeing notification process, when the winning stop symbol mode is determined in the symbol generating process (special game flag = 1 and calculation flag = 0), if there is no undigested special start memory data determined to be a hit (first Second winning flag = 0), the first winning expected value obtained by the above first winning expected value generating process is validated. Then, one of the prediction symbol modes a to e is selected in accordance with the first winning expected value by the prediction symbol selection process, and the selected prediction symbol aspects a to e are displayed on the symbol display device 14 by the prediction symbol display process. To do. On the other hand, in the above case (special game flag = 1 and calculation flag = 0), if there is undigested special start storage data determined to be a win (second winning flag = 1), the above-described second winning expected value generation process The second winning expected value generated by the above is validated, and the foreseeing symbol selection process and the foreseeing symbol display process are executed according to the second winning expectation value.

  Here, the foreseeable symbol selection process is a process for selecting the foreseeable symbol patterns a to e set in advance according to the first winning expected value or the second winning expected value. This selection process is performed when either of the first winning expected value or the second winning expected value exceeds 40%, and one of the foreseeable design patterns a and b is extracted, and when it exceeds 30% and is 40% or less. Extract any one of the foreseeable design aspects b and c, extract any one of the foreseeable design aspects c to e in the case of 20% or more and 30% or less, and extract the foreseeable design aspect d or less in the case of being less than 20%. This is performed by extracting one of e. These extraction processes are performed randomly.

  And it displays on the symbol display apparatus 14 via the production | presentation control base | substrate 82 according to the prediction symbol aspect selected by the prediction symbol selection process by the prediction symbol display process. Thereby, the prediction notification is performed based on the first winning expected value or the second winning expected value. In addition, for the foreseeable design patterns a to e of the present embodiment, the production pattern is set as the production mode by the predetermined foreseeable design. For example, in the foreseeable design aspect a, a predetermined foreseeable symbol is displayed according to the effect pattern. As described above, a predetermined foreseeable design and an effect pattern are set for each of the foreseeable design modes a to e. And one of the foreseeable design aspects a to e is selected, and the foreseeing notification is performed by executing the effect according to the selected aspect.

  In this foreseeing notification process, when there is no special start storage data determined to be a win in the special gaming state (special game flag = 1) (second winning flag = 0), as described above, it is once valid. Since the first winning expected value is maintained (calculation flag = 1), the foreseeable symbol mode displayed on the symbol display device 14 is maintained by the foreseeable symbol selecting process and the foreseeable symbol displaying process. On the other hand, by the above-described second winning expected value generation process (see FIG. 8), it is determined that the newly generated undigested special start stored data is a hit in the state of the second winning flag = 0, and the second winning expected value Is generated (generation flag = 1), the second winning expected value is validated, and the foreseeing symbol selection process and the foreseeing symbol display process are performed.

  Further, in the foreseeing notification process, in the probability variation state after the end of the special gaming state (probability variation flag = 1), if there is no undigested special start memory data determined to be a winning (second winning flag = 0), symbol generation Each time the lost stop pattern mode is determined by the process (decrease flag = 1), the first winning expected value newly calculated by the first winning expected value generation process is validated. Then, according to the first winning expected value, a foreseeing symbol selection process and a foreseeing symbol display process are performed. Here, since the first winning expectation value changes every time the remaining probability variation number decreases as described above, the predictive symbol form is displayed according to the changed value. On the other hand, if there is undigested special start memorized data determined to be a win in the probability changing state (second winning flag = 1), every time the second winning expected value is generated by the second winning expected value generating process described above. (Generation flag = 1), the foreseeable symbol selection process and the foreseeable symbol display process are performed according to the latest expected second winning value. Here, the second winning expectation value is determined when the newly won undigested special start storage data is determined to be a win when the second winning flag = 0, or when the second winning flag = 1. When the loss stop symbol pattern is determined by the symbol generation process (decrease flag = 1), the symbol is generated by the second winning expected value generation process. Therefore, every time the second winning expectation value is newly generated, processing for selecting and displaying the foreseeable design aspect according to this is performed.

  In this way, in the foreseeing notification process, when the winning stop symbol mode is determined by the symbol generation process and the special game state is entered, the foreseeable symbol modes a to e selected according to the first winning expected value or the second winning expected value are displayed as symbols. Each time the first winning expectation value or the second winning expectation value is newly generated until it is displayed on the device 14 and then the probability variation state ends, the prediction symbol forms a to e are selected and displayed again accordingly. . Thereby, it is possible to predict and predict the possibility of occurrence of a hit in the certain probability change state in accordance with the progress of the game between the start of the special game state and the end of the probability change state. The predictive symbols a to e to be notified of the prediction include the first winning expected value calculated based on the remaining probability variation number and the winning probability (high probability) of the probability variation state, or the undigested special start memory data determined to be a win. If there is, the selection is made according to the second winning expectation value obtained based on the determination result and the remaining probability variation number. For this reason, the foreseeing notification performed by displaying the foreseeable design patterns a to e can accurately predict the possibility of being hit in the probability variation state. Therefore, the player can know the possibility that the winning will occur in the probability variation state by the foreseeable symbol forms a to e displayed on the symbol display device 14, and the possibility is relatively high. It is possible to maintain the reliability with respect to the foreseeing notification of the person, and to fully exhibit the taste of the foreseeing notification.

  In this embodiment, the first winning expected value and the second winning expected value are generated as values (%) indicating the possibility of occurrence, and five types assigned to the value (%) are generated. The foreseeable design aspects a to e are selected. Therefore, since the foreseeable design aspects a to e have accuracy and some uncertainties, it is possible to perform foreseeing notification that stimulates interest while maintaining high accuracy.

  In the configuration of the present embodiment, the first winning expected value generation means according to the present invention is configured by the main control board 80 that performs the first winning expected value generation processing. Moreover, the second winning expected value generating means according to the present invention is configured by the main control board 80 that performs the second winning expected value generating process. The main control base 80, the effect control base 82, and the symbol display device 14 that perform the prediction notification processing constitute the prediction notification means according to the present invention.

  In the above-described embodiment, the process for generating the first winning expected value (calculation process) and the process for generating the second winning expected value (generation process) are not limited to this processing method, and may be performed by various methods. It is possible to generate. For example, in the generation process of the first winning expected value, there is a possibility that each symbol generation process of the remaining probability variation number may be hit by the winning probability of the probability variation state, and a plurality of pseudo values corresponding to the remaining probability variation number are calculated. It may be set in advance, and the pseudo value may be selected and assigned to the first winning expected value in accordance with the remaining probability variation number. Note that the first winning expected value is not limited to a numerical value, and may be a value that can quantitatively represent the rank. The same applies to the generation process of the second winning expected value.

  In the above-described embodiment, the prediction display is performed by displaying the effect according to a predetermined effect pattern (predictive symbol aspect) on the symbol display device. However, the specific predictive symbol is displayed as a symbol. Foreseeing notification can also be performed by displaying on the device. In addition, as the foreseeing notification, each of the above-described first winning expected value and second winning expected value may be displayed as a percentage value, instead of the effect design. Furthermore, a predetermined notification device that performs prediction notification may be provided as a separate member from the symbol display device.

  Further, in the above-described embodiment, as soon as the winning symbol pattern is determined in the symbol generation process, the state immediately becomes probable, and the first winning expectation value and the second winning expectation value are generated and the prediction notification is performed. However, it is also possible to make a prediction change notification immediately after the end of the special game state by setting the probability change state by the end of the special game state. In addition, this foreseeing notification may be executed only once immediately after the state of probability change.

  Further, the process for generating the second winning expected value is not limited to the probability variation state, and the second winning expected value may be generated even in the normal probability state. In this case, in the normal probability state, a hit determination is made according to the winning probability (normal probability), and if it is a win, a second winning expected value is generated based on the determination result, and a prediction is made according to the second winning expected value. Notification.

  In this invention, it is not limited to the Example mentioned above, About another structure, it can change suitably within the range of the meaning of this invention.
