  When the special symbol control process is started, the process proceeds to step 11 to load a control state flag. This control state flag indicates the state of the special symbol game using the symbol variable display image on the liquid crystal display device 16, and data for determining which of the steps 12 to 20 is executed by the main CPU 31 is set. ing.

  Next, it progresses to step 12 and a special symbol memory | storage check process is performed. The special symbol memory check process is performed according to the flowchart shown in FIG. When starting the process, the main CPU 31 proceeds to step 21 to determine whether or not the control state flag is “00” indicating the special symbol memory check. If it is not “00”, the special symbol memory check process is terminated. If “00”, the process proceeds to step 22 to determine whether or not the reserved number stored in the main RAM 33 is “0”. If the reserved number is “0”, the process proceeds to step 23 to perform a demo display process. The process ends. On the other hand, if the reserved number is not “0”, the process proceeds to step 24 to set “01” indicating the special symbol variation time management to the control state flag.

  Next, the process proceeds to step 25 where pre-processing for jackpot determination is performed. At this time, the main CPU 31 refers to a high probability flag for distinguishing whether the transition probability is high or normal. If the high probability flag is set using the random number for jackpot determination extracted when the game ball wins the start winning opening 9, the jackpot determination table for probability variation is referred to, otherwise Searches the normal jackpot determination table.

  When the processing proceeds to the subsequent step 26, the main CPU 31 operates as a transition condition determination means of the present invention, and performs a big hit determination process for determining whether or not a big hit is made based on the search result of the big hit determination table. The big hit determination table stores a plurality of types of random values that mean a big hit. The main CPU 31 determines that it is a big hit (determines that the game state transition condition has been established) when the extracted random number for jackpot determination matches any one of the random values that mean the big hit stored in the jackpot determination table. Then, the process proceeds to step 27 to perform a big hit symbol determination process. On the other hand, if the jackpot determination random number value extracted by the main CPU 31 does not match the random value meaning the jackpot, it is determined to be out of play (determined that the gaming state transition condition is not established), and the process proceeds to step 28 to determine the out of play symbol. Processing is performed.

  In the big hit symbol determination process, the main CPU 31 obtains a special symbol from the random number value for the big hit symbol (not shown) and a special symbol determination table (a table storing the symbol command and the special symbol type in association with each other). Further, a symbol command corresponding to the determined special symbol is set as a transmission command to the sub-control circuit 40. In addition, there are “0” to “9” (a total of 10 types) as the special symbols as the specific display mode according to the present embodiment. In the big hit symbol determination process, the variable symbol display result of the special symbol is used as the specific display mode. The special symbol is determined so as to be any one of “0” to “9”.

  In this way, the determination that the main CPU 31 is a big hit in step 26 means that the variable symbol display result of the special symbol is one of a plurality of types of specific display modes. The main CPU 31 displays the variable symbol display result of the special symbol. Is in any of a plurality of types of specific display modes, it is determined that the game state transition condition is satisfied.

  Thereafter, the main CPU 31 proceeds to step 29, searches a variation pattern table (not shown), determines a variation pattern command corresponding to the random number value, and transmits it to the sub-control circuit 40. In step 30 that follows, the main CPU 31 sets the variation time corresponding to the variation pattern determined in step 29 in the waiting time timer (t). Further, the storage area used for the current variation is cleared, and the special symbol storage check process is terminated.

  Then, following the special symbol memory check process, the process proceeds to step 13 shown in FIG. 8, and a special symbol variation time management process is performed. In the special symbol variation time management process, the following processing is performed when the control state flag is “01” indicating special symbol variation time management, and if it is not “01”, the following processing is not performed. . That is, the main CPU 31 sets “02” indicating the special symbol display time management to the control state flag when the waiting time timer corresponding to the variation time becomes “0”, and sets the waiting time after confirmation (for example, 1 second). ) Is set in the waiting time timer (t). When this process ends, the special symbol variation time management process ends.

  Next, it progresses to step 14 and a special symbol display time management process is performed. The special symbol display time management process is performed according to the flowchart shown in FIG. When the process starts, the main CPU 31 proceeds to step 31 to determine whether or not the control state flag is “02” indicating special symbol display time management. If it is not “02”, the main CPU 31 ends the special symbol display time management processing. If "02", the process proceeds to step 32, and it is determined whether or not the waiting time timer (t) corresponding to the waiting time after determination is "0". If the waiting time timer (t) is not “0”, the special symbol display time management process ends. If it is “0”, the process proceeds to step 33 to check whether the result of step 26 (see FIG. 9) is a big hit. Determine.

  If it is determined in step 33 that the game is not a big hit, the process proceeds to step 36 where "08" indicating the end of the special symbol game is set in the control state flag, and the special symbol display time management process is terminated. On the other hand, if it is determined in step 33 that the game is a big hit, the process proceeds to step 34, where "03" indicating the big hit start interval management is set in the control state flag. Then, when proceeding to the subsequent step 35, a time corresponding to the big hit start interval (for example, 10 seconds, hereinafter referred to as “hit start corresponding time”) is set in the waiting time timer (t), and further, a big hit start command is set. Thereafter, the special symbol display time management process ends.

  When the special symbol display time management process ends, the process returns to FIG. 8 and proceeds to step 15 where the jackpot start interval management process is performed. In this jackpot start interval management process, when the control status flag is “03” indicating the jackpot start interval management, the jackpot 11 is opened after waiting for the jackpot start corresponding time, and the jackpot opening command is set. Further, when the main CPU 31 sets “04” indicating that the big winning opening is open to the control state flag and sets the opening upper limit time (for example, 30 seconds) in the big winning opening time timer, the big hit start interval management process is ended. .

  Next, the process proceeds to step 16 where a special winning opening opening process is performed. The process during opening of the special winning opening is performed according to the flowchart shown in FIG. When the process starts, the main CPU 31 proceeds to step 41 to determine whether or not the control status flag is “04” indicating that the big prize opening is open. If "04", the process proceeds to step 42, and step 43 is executed depending on the determination result of step 42. In step 42 and step 43, whether or not each of the big prize winning counters is equal to or greater than the maximum number of winning (for example, “10”), or whether or not the upper opening limit time has passed (the big prize opening time timer is set). "0") is determined, and when any of these conditions is satisfied, that is, when the normal closing condition is satisfied, the process proceeds to step 45 without executing step 44, and remains in the big prize opening in the control state flag Set “05” to indicate sphere monitoring. Further, in the pachinko gaming machine 1 according to the present embodiment, even if the above normal closing condition is not established, the process proceeds to the subsequent step 44 and a special closing condition (switching condition in the present invention) is established in a closing flag described later. It is determined whether or not “1” indicating “1” is set. If “1” is set, the process proceeds to step 45 to set “05” indicating monitoring of the residual ball in the special winning opening. If “1” is not set, neither the normal closing condition nor the special closing condition is established, and in this case, the process for opening the big prize opening is ended.

  When the process proceeds to step 45 and “05” indicating the supervision of the remaining ball in the special prize opening is set, the process proceeds to the next step 46 where the main CPU 31 performs the closing setting of the special prize opening and the shutter of the special prize opening 11 by the special prize opening solenoid 11L. To close. By closing the shutter of the big prize opening 11, one round during the big hit ends, and the game ball enters the big prize opening 11 (easy to win) from the easy winning state to the difficult to win state (difficult to win). Switch.

  When the processing proceeds to the subsequent step 47, the main CPU 31 sets the remaining winning ball in-mouth monitoring time (for example, 1 second) in the waiting time timer so as to execute step 17 after elapse of the remaining winning ball in-watch monitoring time. If the closing flag is cleared, the process for opening the special winning opening is completed and the routine proceeds to step 17 shown in FIG.

  When the process proceeds to step 17 (see FIG. 8), the winning ball residual ball monitoring process is performed. The special winning opening residual ball monitoring process is performed according to the flowchart shown in FIG. When the process is started, the main CPU 31 proceeds to step 51 to determine whether or not the control state flag is “05” indicating monitoring of the winning ball remaining ball in the winning game mouth. If "05", the process proceeds to step 52, and it is determined whether or not the waiting time timer (t) corresponding to the winning ball remaining ball monitoring time is "0". Here, if the waiting time timer (t) is not “0”, the monitoring of the remaining ball in the big prize opening is finished, and if it is “0”, the process proceeds to step 53 and the number of times the big prize opening is opened is the maximum number of times (this embodiment 15 times or more), and if the number of opening of the big winning opening is 15 times or more, it is determined that the normal big hit end condition is satisfied and the routine proceeds to step 54, where the control status flag indicates the big hit end interval “ Set 07 ". When proceeding to the subsequent step 55, the main CPU 31 sets a time corresponding to the jackpot end interval (hereinafter referred to as “hit end corresponding time”) in the waiting time timer, and after the jackpot end corresponding time has elapsed, step 19 (the end of the big hit) Interval) is executed.

On the other hand, the main CPU 31 determines that the normal big hit end condition is not satisfied when the number of open big winning opening is less than 15 in step 53, and proceeds to step 56 to extract the random number for determining the big hit end and proceeds to step 57. move on.
When proceeding to step 57, the main CPU 31 refers to the jackpot end determination table T1 as shown in FIG. 18, and the extracted jackpot end determination random number value matches the predetermined determination value stored in the jackpot end determination table T1. It is determined whether or not the big hit ends, if it matches, it is determined that the big hit ends due to the establishment of the big hit sudden termination condition, and the process proceeds to step 54. Then, the process proceeds to step 58. In the jackpot end determination table T1, determination values are stored such that the jackpot end determination probability becomes the predetermined probability illustrated in association with the special symbol specific display mode ("0" to "9"). For example, in the case of the special symbol “0” as the specific display mode, when the jackpot end determination probability is 50%, that is, when the extracted random number values are 100 from “0” to “99”, Are stored as determination values, and in the case of the special symbol “2” as the specific display mode, the number of the jackpot end determination probability is 25% (corresponding to the special symbol “0” as the specific display mode) Half of the number of judgment values is stored. The main CPU 31 determines the jackpot end determination table T1 in which the jackpot end determination random number value extracted in step 56 corresponds to the special symbol specific display mode determined in the jackpot symbol determination process in step 27 (see FIG. 9). The success or failure condition of the big hit is determined depending on whether or not it matches the determination value. In FIG. 18, for the sake of convenience, the jackpot end determination probability is shown instead of specifically indicating the number of determination values associated with the specific display mode.

  If it is determined in step 57 that the sudden success termination condition is not established, the process proceeds to step 58 where “06” indicating the management of reopening waiting time for the big prize opening is set in the control state flag. The time corresponding to the interval is set in the waiting time timer, and the winning ball residual ball monitoring process is completed.

  Then, returning to FIG. 8, the process proceeds to step 18 where the waiting time management process before reopening the big winning opening is performed. In the waiting time management process before reopening the big winning opening, when the control state flag is “06” indicating the waiting time management before reopening the big winning opening, after the waiting time has elapsed, step 18 is executed as follows. Processing is performed, and if it is not “06”, the following processing is not performed. After the time corresponding to the interval between rounds has elapsed, the main CPU 31 adds “1” to the special winning opening opening number counter. Subsequently, the special winning opening is set to open, "04" indicating that the special winning opening is open is set in the control state flag, the special winning opening time timer (s) is set, and the special winning opening start command is set. When this is done, the waiting time management process before reopening the big prize opening ends.

  Next, the process proceeds to step 19 to perform a big hit end interval process. In the big hit end interval processing, the following processing is performed when the control state flag is “07” indicating the big hit end interval, and if it is not “07”, the following processing is not performed. At this time, the main CPU 31 sets “08” indicating the end of the special symbol game to the control state flag and sets the jackpot end command indicating the end of jackpot after the waiting time timer has elapsed, and the jackpot symbol is an odd symbol. If there is, a high probability flag is set and a high probability command is set.

  Next, when the big hit end interval process is completed, the process returns to FIG. 8 and proceeds to step 20, where a special symbol game end process is performed. Here, the following process is performed when the control state flag is data “08” indicating the special symbol game end process, and if it is not “08”, the process is not performed. The main CPU 31 updates the number of reserved balls so as to decrease by “1”. When “00” indicating the special symbol storage check is set in the control state flag, the storage area used for the current variation is further cleared, and the special symbol game end process is terminated.

  With the above, the special symbol control process in step 2 is completed, and the normal symbol control process shown in FIG. When the process is started, the normal symbol control state flag is read, and the normal symbol variable display time and the state of the stopped normal symbol are monitored according to the flag. When the normal symbol mode is a predetermined mode, the variable indicating the opening and closing of the pair of blades 9a provided in the start winning opening 9 is stored in the main RAM 33, and the normal symbol control process ends.

  Progressing to step 4 following step 3, random number update processing is performed. Here, random number update processing for updating the random symbol value for losing symbols, random value for reach determination, random number value for effect condition selection, and the like by a predetermined calculation method is performed, and the processing is terminated. Then, returning to step 2, the repeat routine is repeated.

(System timer interrupt processing procedure)
The main control circuit 30 executes a system timer interrupt process that interrupts the main control process along the flowchart shown in FIG. 13 together with the main control process described above. Hereinafter, the operation procedure of the system timer interrupt process will be described with reference to FIGS.

  When the pachinko gaming machine 1 starts the system timer interrupt process, the process proceeds to step 81, and after temporarily saving the program that is executing the main control process stored in the storage area (register) in the memory, the process proceeds to step 82. move on. In step 82, the main CPU 31 performs update processing of random numbers used for jackpot determination, variation pattern of special symbol J, etc., and proceeds to step 83 to perform switch input detection processing.

  As shown in FIG. 14, the switch input detection process ends when a prize ball related switch check process, a special symbol related switch input process, and a normal symbol related switch input process are performed in steps 101 to 103.

  Here, when the special symbol related switch input process is started, as shown in FIG. 15, the process proceeds to step 111 to determine whether or not there is an input from the count switch 11CS. The process proceeds to step 113 when the count switch is detected. If there is no input, the process proceeds to step 113 without executing step 112.

  The count switch detection process is performed according to the flowchart shown in FIG. When starting the process, the main CPU 31 proceeds to step 121 to determine whether or not the special winning opening 11 is open. If it is open, the process proceeds to step 122. If not open, the following processes are not executed. The process at the time of detecting the count switch ends. Then, when proceeding to step 122, the main CPU 31 adds “1” to the grand prize winning prize counter.

  When the processing proceeds to the subsequent step 123, the main CPU 31 operates as a display mode determination means in the present invention, and performs jackpot symbol determination. Here, the main CPU 31 determines which of the plural types of specific display modes (“0” to “9”) is the special symbol in the big hit symbol determination process in step 27 (see FIG. 9).

  When the processing proceeds to the subsequent step 124, the main CPU 31 operates as probability determination means in the present invention, and refers to a closing determination table T2 as shown in FIG. 19 to determine whether or not a special closing condition (switching condition in the present invention) is successful. The closing determination probability (determination probability of the present invention) is determined. In the closing determination table T2, determination values are stored such that the closing determination probability becomes the predetermined probability illustrated in association with the special symbol (“0” to “9”) as the specific display mode. For example, in the case of the special symbol “0”, when the probability of closing is 50%, that is, when the random number extracted in the subsequent step 125 is 100 from “0” to “99”, 50 The number is stored as the determination value, and in the case of the special symbol “2”, the determination value is stored so that the closing determination probability is 25% (half the number corresponding to the special symbol “0”). The main CPU 31 acquires the determination value of the closing determination table T2 corresponding to the special symbol specific display mode determined in step 123, and determines the closing determination probability (for example, the closing determination in the case of the special symbol “0”). The probability is 50%). In FIG. 19, for the sake of convenience, the closing determination probability is shown instead of specifically indicating the number of determination values associated with the specific display mode.

  When the process proceeds to the subsequent step 125, the main CPU 31 extracts the random number for closing determination and proceeds to step 126. When proceeding to step 126, the main CPU 31 operates as a switching condition determining means in the present invention, and whether or not to close the special winning opening 11 and end one round, that is, a special closing condition corresponding to the switching condition of the present invention. Determine success or failure. Here, the main CPU 31 determines whether or not the closing determination random number value extracted in step 125 matches any of the determination values based on the predetermined closing determination probability determined in step 124. The process proceeds to 127, and when there is a mismatch, the process at the time of detecting the count switch ends without performing the process of step 127. When proceeding to step 127, the main CPU 31 sets "1" to the closing flag in order to close the special winning opening 11 and end one round, and the count switch detection time processing is ended.

  Returning to FIG. 15 and proceeding to step 113, it is determined whether or not there is an input from the start winning opening switch 9S, and when there is an input, the process proceeds to step 114 and processing for detecting the starting winning opening is performed. When the related switch input process is finished and there is no input from the start winning opening switch 9S, the special symbol related switch input process is finished without performing the start winning opening detecting process.

  The switch input detection process in step 83 is completed as described above, and then the timer update process in step 84 shown in FIG. 13 is performed. In the timer update process, a timer that synchronizes the main control circuit 30 and the sub control circuit 40 is updated. In the subsequent step 85, game information data generation processing is performed to generate an output signal from the pachinko gaming machine 1 to a hall computer (not shown). Then, the process proceeds to step 86, and output processing such as controlling each solenoid 9L, 11L and ON / OFF of the motor based on the data stored in the main RAM 33 is performed. In the subsequent step 87, command output for outputting various commands such as symbol commands and variation pattern commands is performed, and various commands are output to the sub-control circuit 40. Further, following steps 88 and 89, a lamp control process (a process for outputting a lamp lighting signal to the sub-control circuit 40) and a payout process (a prize ball command including data indicating the number of prize balls is output to the payout device 81). The payout device 81 pays out a prize ball corresponding to the prize ball command. Further, in step 90, the register in which the program under execution of the main control process is stored is restored, and the main control process is resumed from the point where the main control process is interrupted (the program being executed is saved). Further, when the routine proceeds to step 91 and the variables, flags, etc. of the main RAM 33 are updated and the interrupt is permitted, the system timer interrupt process ends.

(Sub-control circuit operation procedure)
Next, the operation of the sub control circuit 40 will be described. The sub control circuit 40 receives the command transmitted from the main control circuit 30 and performs symbol display control, sound control, lamp control, and the like. FIG. 17 is a flowchart showing a procedure of sub control processing repeatedly executed by the sub control circuit.

  As shown in FIG. 17, the sub CPU 41 sequentially executes steps 201 to 206 to perform initialization processing, random number update processing, command analysis control processing, display control processing, audio control processing, and lamp control processing. Then, steps 202 to 206 are repeatedly executed.

  In the display control process, the sub CPU 41 instructs the image control circuit 50 in accordance with the result of the command analysis process based on the command from the main control circuit 30, and displays a design or the like on the display area 16a of the liquid crystal display device 16. In this display control process, the VDP 51 reads image data such as symbols and characters from the image data ROM 54, converts this image data into a predetermined image signal by the D / A converter 52, and displays, for example, symbols and characters. 16a is displayed so as to be operated on 16a.

  In the voice control process, the sub CPU 41 instructs the voice control circuit 60 in accordance with the result of the command analysis process based on the command from the main control circuit 30, and outputs the voice from the speakers 18L and 18R. In this sound control process, the sound source IC 61 reads sound data from the sound data ROM 63, converts the sound data into a predetermined sound signal, and supplies the sound signal to the AMP 62. The AMP 62 amplifies the sound signal and generates sound from the speakers 18L and 18R.

  In the lamp control process, the sub CPU 41 instructs the lamp control circuit 70 in accordance with the result of the command analysis control process based on the command from the main control circuit 30, and turns on or off the decoration lamps 19L and 19R. In this lamp control process, the sub CPU 41 reads the lamp decoration pattern from the decoration data ROM 71 and blinks the decoration lamps 19L and 19R via the drive circuit 72.

  As described above, in the pachinko gaming machine 1, when the game state shifts to the big hit and the round control starts, the game ball wins the big winning opening 11, and every time there is an input from the count switch 11CS, a predetermined closing determination is made. It is determined at random whether or not the special winning opening 11 is closed. Therefore, for example, one round may be completed by winning five balls, or one round may not be completed until winning ten balls, and game balls are paid out when all rounds of big hits are digested. The number of (also called out balls) changes. Therefore, the player has a strong interest in how long each round will last, and can play games with the expectation that the round will last for a long time. Compared to the conventional pachinko machines that were easy to play, the fun of the game can be improved. Furthermore, because there is a gap in the profits obtained when all rounds are consumed, the player's feelings and expectation for entering the game ball during one round become stronger, and the interest in the game during the big hit is less likely to fade. Improve the fun of gaming. Furthermore, the operation effect that closes the grand prize opening 11 in a different closing pattern during the first round enables a continuous effect that motivates the player to continue playing the game, and the player wins a big hit. In addition to the transition, you will be able to enjoy exciting points even during the big hit.

  Further, in the pachinko gaming machine 1, since the determination probability for ending one round is determined every time a big hit is made, the determination probability changes every big hit. For this reason, the expected value of the number of game balls to be won in the big winning opening 11 per round changes for every big hit, and the expectation for the game during the big hit is expanded. In particular, even if a player who has continued to play a game and wins the jackpot many times, it will be difficult to predict the pattern in which one round will end or the number of balls that will be earned in one round. In addition, the desire to manage a lot of game balls in the grand prize opening 11 is strengthened, and the expectation is further increased.

  Furthermore, since the determination probability changes depending on the type of the specific display mode derived as the variable display result of the special symbol meaning the big win, the game ball that wins the variable winning device per round according to the variable symbol display result of the special symbol As the expected value of the number changes, the expectation also changes, and the gameability is further improved.

  In addition, in the pachinko gaming machine 1, when a special closing condition based on the closing determination probability is established in addition to the normal closing condition in which the big winning opening 11 is closed when a predetermined number of game balls are won in one round, the big winning opening 11 is Close and end one round. Unlike the normal closing condition that is inevitably established when the game is continued, the special closing condition is established with a predetermined closing determination probability. Therefore, when the special closing condition is established and the special winning opening 11 is closed, The player unexpectedly felt that the grand prize opening 11 was suddenly closed and the round ended, and novelty and novelty were born there, compared to conventional pachinko games where monotonous games continued. The fun of gaming can be improved and new game characteristics can be provided in pachinko games

  Further, in the pachinko gaming machine 1, even if the normal big hit end condition (for example, the end of 15 rounds) is satisfied, the big hit ends when the big hit sudden end condition is satisfied. In this way, the big hit can be suddenly ended before the number of times of opening the big prize opening reaches 15. When the conventional pachinko gaming machine 1 is a big hit, the number of times the opening of the big prize opening 11 is set to 15 times, for example, and the player can have a sense of security that the big hit will continue until the number of times the opening reaches 15 times. This contributed to the continued monotonous game after the big hit. However, the pachinko gaming machine 1 gives the player the unexpectedness that the jackpot ends abruptly, so the interest in the game is difficult to fade, and the interest of the game after shifting to the jackpot can be improved, with a new pattern It is possible to provide new game characteristics in which the game progresses. In addition, the probability that the jackpot ends will vary depending on the special symbol when the jackpot is won, so the player can have a sense of anticipation of how long the jackpot will last, and the fun of the game can be further improved. .

  When the game program is read from the ROM and executed by the CPU, the pachinko game in the pachinko gaming machine 1 described above can be simulated in the personal computer 300.

  In the personal computer 300, the game program is stored in the ROM, but may be stored in a storage medium such as a CD-ROM. Further, as shown in FIG. 21, a personal computer 300 may be connected to a server 401 that stores a game program via a network 400, and the game program may be downloaded from the server 401. Instead of the personal computer 300, the game program may be executed by a mobile terminal such as a mobile phone.

  In the above embodiment, the case of a single-type pachinko machine has been described as an example, but the present invention may be applied to two types (so-called Hikoki) and three types (so-called rights) of pachinko machines. Further, it is not necessary to determine the closing determination probability or jackpot end determination probability according to the special symbol specific display mode. For example, the closing determination probability or jackpot end determination probability may be determined by lottery for each jackpot. Conversely, the closing determination probability or jackpot end determination probability may be always constant (for example, 50%), and the timing for determining the closing determination probability or jackpot end determination probability is not every jackpot, It can be done every 30 minutes or every month. Furthermore, the closing determination probability and the jackpot end probability may be changed every end of one round. Note that only the closing determination probability may be determined, and the jackpot end determination probability may not be determined.
