Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine that displays a result of a big hit determination for shifting from a normal gaming state to a big hit gaming state.

  In gaming machines such as pachinko machines and slot machines, which are ball game machines, a specific gaming state in which many prize balls can be obtained (big hit gaming state) and a normal state in which there are few opportunities to obtain prize balls (normal gaming state) ) Are known. Since it is easier to obtain more prize balls when in the big hit game state, the player plays a game aiming to shift from the normal state to the big hit game state, and increases interest. There is also known a gaming machine that displays a specific jackpot symbol on a symbol display device when the transition from the normal gaming state to the jackpot gaming state is made, and notifies the player that the game will shift to the jackpot gaming state.

As such a gaming machine, for example, there is a gaming machine disclosed in Japanese Patent Laid-Open No. 2002-346092 (Patent Document 1). This gaming machine informs the image display device that a plurality of symbols are changed and the game is shifted to the big hit gaming state according to the stop mode of the plurality of symbols when the symbols are stopped. At this time, when the symbol that is stopped and displayed is not a combination of jackpot symbols, but a combination of symbols that are out of sync, the display of variation is started again to maintain the player's sense of expectation for the jackpot.
JP 2002-346092 A

  However, in the gaming machine disclosed in the above-mentioned Patent Document 1, although the player's sense of expectation for the big hit is maintained by re-variation, eventually, the combination of symbols is stopped, so that the big hit game is achieved. Whether or not the transition is performed will be notified. Therefore, after all, the mode of transition to jackpot has to be monotonous, and it has been difficult to effectively improve the interest of the game.

  Therefore, an object of the present invention is to provide a gaming machine that can effectively improve the interest of the game by diversifying the mode of transition to jackpot.

The gaming machine according to the present invention that has solved the above problems is a display device for displaying an identification symbol composed of a combination of a plurality of symbol elements, and a symbol in the identification symbol after variably displaying the identification symbol displayed on the symbol display device. Display control means for performing display control for stopping and displaying an element; jackpot gaming state transition determining means for determining whether or not to shift from a normal gaming state to a jackpot gaming state that is more advantageous to the player than the normal gaming state; A game machine comprising symbol determining means for determining an identification symbol displayed on the symbol display device based on the jackpot determination result in the jackpot gaming state transition determining means, wherein the symbol determining means is a jackpot gaming state transition determining means When it is determined that a transition to the jackpot gaming state is made, it is possible to determine a special jackpot identification symbol including a special symbol element as a symbol element, When it is determined by the winning game state transition determining means to shift to the big hit gaming state, the display control means, if the identification symbol determined by the symbol determining means is other than the special big hit identifying symbol, the big hit gaming state transition If all the symbol elements are stopped and displayed before, and the identification symbol determined by the symbol determination means is a special jackpot identification symbol, a part of the symbol elements including the special symbol element is stopped before the big hit gaming state transition. Rutotomoni is displayed, the rear jackpot gaming state migrate symbol elements other than a part of symbols elements including special symbol elements continues also varied continuously displayed, after a predetermined time after the jackpot gaming state transition, special jackpot identification symbols in one of the symbol elements continues to be varied continuously displayed from the previous jackpot gaming state transition, but for displaying stop symbol elements not displayed stopped That.

  In the gaming machine according to the present invention, it is possible to determine a special jackpot identification symbol including a special symbol element as a symbol element among the jackpot identification symbols that notify the transition to the jackpot gaming state. Also, when this special jackpot identification symbol is stopped and displayed, only a part of the special jackpot identification symbol including the special symbol elements is stopped and displayed before the big hit gaming state transition. Before everything is stopped and displayed, the transition to the jackpot gaming state is notified, and some symbol elements are shifted to the jackpot gaming state while being variably displayed. On the other hand, when the jackpot identifying symbol is other than the special jackpot identifying symbol, all the jackpot identifying symbols are stopped and displayed before the jackpot gaming state transition. In this way, when the jackpot identification symbol is stopped and displayed, the special symbol elements are displayed, so that even if all the jackpot identification symbols are not stopped and displayed, the transition to the jackpot gaming state is notified and the jackpot gaming state Therefore, it is possible to effectively improve the interest of the game by diversifying the mode of transition to the big hit gaming state.

  Further, since the transition to the big hit gaming state is determined by stopping and displaying some of the symbol elements, it is possible to have a lot of expectation when the identification symbols that are variably displayed are stopped and displayed. Specifically, for example, there are three symbol elements, and when each symbol element is stopped and displayed in order, a special symbol element is displayed on the symbol element that is stopped and displayed first, so that the transition to the big hit gaming state is achieved. It is determined. Even if the special symbol element is not displayed in the symbol element that is first stopped, the transition to the big hit gaming state is determined by the special symbol element being stopped and displayed in the symbol element that is stopped and displayed next. The In addition, even after the second symbol element is stopped and displayed, if the symbol element that is stopped and displayed last is a special symbol element, the transition to the big hit gaming state is determined. In this way, even if the symbol that is first stopped and displayed is not a special symbol element, the player can have a sense of expectation of transition to the big hit gaming state.

Here, as the big hit gaming state, the normal big hit gaming state that shifts to the normal gaming state after the big hit gaming state ends, and the preferential normal gaming state that easily shifts to the big hit gaming state after the big hit gaming state ends And a special jackpot game state transition determining means for determining whether to shift to a normal jackpot game state or a special jackpot game state, and the symbol determining means is a jackpot game When it is determined by the state transition determining means to shift to the jackpot gaming state and when it is determined by the special jackpot gaming state transition determining means to shift to the special jackpot gaming state, a special symbol element and a predetermined after the jackpot gaming state transition a symbol element stopped and displayed after the time and special symbols associated symbol elements is a special symbol components identical symbols Is determined to shift to the big hit gaming state by the big hit gaming state transition judging means, and when it is judged to shift to the normal big hit gaming state by the special big hit gaming state transition judging means In addition, a special special jackpot identifying symbol that includes a special symbol element and a symbol element that is stopped and displayed after a predetermined time has passed since the transition to the jackpot gaming state and is a special symbol that is not the same as the special symbol element. It can be set as the aspect which determines.

  Thus, in the gaming machine according to the present invention, the special jackpot gaming state and the normal jackpot gaming state are set as the jackpot gaming state. Here, when shifting from the normal gaming state to the jackpot gaming state, a special jackpot identifying symbol and a normal jackpot identifying symbol are set as the jackpot identifying symbol, and the jackpot identifying symbol has a special special jackpot identifying symbol, which is usually a jackpot identifying symbol. The symbol usually has a special jackpot identification symbol. These special special jackpot identification symbols and normal special jackpot identification symbols both include special symbol elements. For this reason, when the special symbol element is stopped and displayed to shift to the big hit gaming state, a part of the identification symbol remains variably displayed. Then, the special symbol related symbol element or the special symbol non-related symbol element is stopped and displayed after a predetermined time has passed after the big hit gaming state transition, and the big hit gaming state shifted according to the display result is the normal big hit gaming state or the special big hit gaming state It can be notified to the player. Therefore, even during the big hit gaming state, the player is shifted to the special big hit gaming state depending on whether or not the symbol elements variably displayed during the big hit gaming state are stopped and displayed as special symbol related symbol elements. Can be expected to improve the fun of the game.

  According to the gaming machine according to the present invention, it is possible to effectively improve the interest of the game by diversifying the transition mode to the big hit.

When J is “7”, a stop display of a predetermined number string including a three-digit number string of odd numbers (symbol corresponding to probability variation big hit) or a special symbol element is made.

  FIG. 6 is a block configuration diagram illustrating mainly the internal configuration of the pachinko gaming machine 1 illustrated in FIGS. 1 to 5. The pachinko gaming machine 1 has a plurality of components centering on the main control circuit 30, the sub control circuit 40, the payout / launch control circuit 80, and the power supply unit 24 described above. 30, sub-control circuit 40 and payout / launch control circuit 80 are connected to each other, and power can be supplied to each. The main control circuit 30 includes a main CPU (Central Processing Unit) 31, a main ROM (Read Only Memory) 32, and a main RAM (Random Access Memory) 33 which are configured by a one-chip microcomputer, and an initial reset circuit 34. And a command output port 35.

  The main CPU 31 inputs a detection signal of a game ball from a count switch 11CS, which will be described later, and operates according to a control program stored in the main ROM 32, so that a pachinko game such as a big hit lottery or a prize ball discharge in the pachinko gaming machine 1 is performed. It controls the operation of the entire gaming machine 1 and transmits various commands to the sub control circuit 40 via the command output port 35. The main CPU 31 performs transition control between the normal gaming state and the big hit gaming state which is a specific gaming state that is more advantageous to the player than the normal gaming state based on the result of the big hit lottery or the digestion of the gaming state. Here, the main CPU 31 constitutes a jackpot gaming state transition means, and winning the jackpot lottery is a transition condition for shifting from the normal gaming state to the specific gaming state.

  In addition to the normal game state and the specific game state, a preferential normal game state that is easier to shift to the specific game state than the normal game state is set as the game state. As the preferential normal gaming state, specifically, a probability variation gaming state and a short-time gaming state are set. In the probability variation gaming state, the winning probability of the big hit lottery in the main CPU 31 is set higher than in the normal gaming state, so that it is easier to shift to the big hit gaming state. In addition, the variation time of the normal symbol is shortened, the winning probability of the normal symbol is set high, the blade 9a of the start winning port 9 is easily opened, and the winning rate to the starting winning port 9 is increased. Also, in the short-time gaming state, the number of changes in the special symbol is increased in a short time by setting the winning probability of the normal symbol higher than in the normal gaming state or by reducing the variation time of the normal symbol. Furthermore, it is easy to open the blade 9a of the start winning opening 9, and the winning ratio to the starting winning opening 9 is increased. Thus, by making it possible to perform many jackpot lotteries in a short time, as a result, it is easy to shift to the jackpot gaming state.

  The main CPU 31 shifts the gaming state to the probability changing gaming state after the probability changing big hit gaming state ends, and shifts the gaming state to the time saving gaming state after the normal big hit gaming state ends. This probable jackpot gaming state becomes the special jackpot gaming state. In the probable game state, the probable game state continues until the next big win lottery win, and in the short-time game state, the short win until the next big win lottery is won or until a predetermined number of, for example, 100 special symbols change display ends. The gaming state continues. The main CPU 31 shifts the gaming state to the jackpot gaming state when winning the jackpot lottery in the short-time gaming state, and shifts the gaming state to the normal gaming state when a predetermined number of special symbol changes have been completed. . In this way, the main CPU 31 controls which of the normal gaming state, the probability variation gaming state, and the short-time gaming state is to be transferred.

  Further, the main CPU 31 causes the special symbol display device 16b to display the special symbol selected from the special symbol determination table shown in FIG. The main CPU 31 determines the special symbol by referring to the result of the big hit lottery in the special symbol determination table. If the winner is selected in the big hit lottery, “-” is selected from the special symbol determination table and displayed as a special symbol on the special symbol display device 16b shown in FIGS. Further, when the big hit lottery is won and the big win is selected, one is acquired from the random number values (0 to 9) generated by the random number acquisition means. When the random number value acquired here is 0-4, the symbol “H” which is usually a big hit is selected and displayed on the special symbol display device 16b. When the acquired random number value is 5 to 9, the symbol “F” that is a probable big hit is selected and displayed on the special symbol display device 16b.

  Further, the main CPU 31 determines a symbol command based on the selected symbol. Specifically, when the selected symbol is “−” corresponding to the loss, the symbol command is determined as z0. When the selected symbol is “H” corresponding to the normal jackpot, the symbol command is determined to be z1. Further, when the selected symbol is “F” corresponding to the probability variation jackpot, the symbol command is determined as z2. The main control circuit 30 transmits the symbol command determined by the main CPU 31 to the sub control circuit 40.

  The main ROM 32 stores a control program executed by the main CPU 31 and permanent data. The main ROM 32 stores a special symbol determination table shown in FIG. 8, a variation pattern table (not shown), and the like. The main RAM 33 temporarily stores data and programs used when the main CPU 31 operates. The main RAM 33 is provided with a transmission buffer for transmitting various commands such as symbol commands and variation pattern commands to the sub-control circuit 40. The initial reset circuit 34 periodically outputs a reset signal to the main CPU 31. With this reset signal, the main CPU 31 executes processing from the beginning of the control program.

  The main control circuit 30 is connected to each switch including the count switch 11CS. The count switch 11CS measures the number of game balls won in the special winning opening 11, and outputs a detection signal indicating the measurement result to the main control circuit 30. The general winning opening switch 12S outputs to the main control circuit 30 a detection signal of a game ball won in each of the general winning openings 12a to 12d. The operation gate switch 10 </ b> S outputs a detection signal of the game ball passing through the normal symbol operation gate 10 to the main control circuit 30. The start winning port switch 9 </ b> S outputs a detection signal of a game ball won in the start winning port 9 to the main control circuit 30. The start condition of the decorative symbol is that the game ball wins the start winning opening 9 and the start winning opening switch 9S detects the game ball.

  The start opening solenoid 9L opens and closes a pair of blades 9a and 9a provided in the start winning opening 9, and the large winning opening solenoid 11L opens and closes a shutter provided in the large winning opening 11. The backup clear switch 26 clears backup data in the event of a power interruption or the like according to the operation of the operator.

  Further, in the pachinko gaming machine 1, when the start winning port switch 9S detects the winning of the game ball and transmits a detection signal, and the main control circuit 30 receives the detection signal, the main CPU 31 in the main control circuit 30 By the big hit lottery, the disappointment, the normal big hit, and the probable big hit are determined. As a result of the big hit lottery, when the normal big hit and the probability variation big hit are determined, the gaming state shifts to a big hit gaming state that is more advantageous to the player than the normal gaming state. As described above, the big hit gaming state includes the normal big hit gaming state and the probability variation big hit gaming state, and the probability changing big hit gaming state is the special big hit gaming state. In addition, while the big hit lottery based on the detection signal is being performed, a maximum of four detection signals are held, and the same number of special symbol holding lamps R1 to R4 are turned on. The main CPU 31 constitutes a jackpot gaming state transition determination unit and a special jackpot gaming state transition determination unit.

  Furthermore, when the big hit of the result of the big hit lottery is a normal big hit, after the specific gaming state is finished, the game shifts to the short-time gaming state. Further, when the big hit is a probable big hit, the game shifts to the probable change gaming state after the specific gaming state ends. On the other hand, when the result of the big hit lottery is out of control, the open / close control of the big winning device is not performed, but when the big hit is won, the big winning port 11 is controlled to open / close. Further, the main control circuit 30 refers to the special symbol determination table shown in FIG. 8, selects a symbol command corresponding to the result of the big hit lottery, and transmits it to the sub-control circuit 40. Specifically, when the result of the big hit lottery is out of place, z0 is selected as the symbol command, and when it is a normal big hit, z1 is selected. Furthermore, z2 is selected when it is a probable big hit. Further, the main control circuit 30 transmits a probability change gaming state command and a time saving gaming state command to the sub-control circuit 40 when the current gaming state is a probability changing gaming state and a time saving gaming state, respectively.

  Further, the main CPU 31 performs a lottery to determine a variation pattern based on the result of the big hit lottery.

(Operation details of pachinko machines)
Next, among the operation contents of the pachinko gaming machine 1, the procedure of control processing by the main control circuit 30 and the sub control circuit 40 will be described with reference to the flowcharts of FIGS. FIG. 12 is a flowchart (main flowchart) showing an operation procedure of a main control process repeatedly executed by the main control circuit 30 after the power is turned on in the pachinko gaming machine 1.

(Operation procedure of main control processing)
As shown in FIG. 12, in the pachinko gaming machine 1, when the power is turned on, the main CPU 31 of the main control circuit 30 starts the main control process, performs an initial setting process (S1), and then performs a special symbol control process (S2). )I do. This special symbol control process will be described later. Thereafter, normal symbol control processing is performed (S3), and then random number update processing is performed (S4). Thereafter, the process proceeds to an iterative routine for sequentially executing the steps S2 to S4. In this main control process, a random number used in the main control process is mainly updated. Therefore, a system timer interrupt process is interrupted and executed periodically (for example, every 2 ms) on condition of setting of an interrupt permission flag. The Various commands such as symbol commands are output from the main control circuit 30 to the sub control circuit 40 by the command output process of the system timer interrupt process.

  The special symbol control process is performed as shown in the flowchart of FIG. When the special symbol control process is started, first, a control state flag is loaded (S11). This control state flag is a flag indicating the state of the special symbol game using the variable display image of the symbol on the liquid crystal display device 16, and data for determining which of the subsequent steps the main CPU 31 executes is included. Is set.

  Next, a special symbol memory check process (S12) is performed according to the procedure of the flowchart shown in FIG. When the special symbol memory check process is started, the main CPU 31 determines whether or not the control state flag is data “00” indicating the special symbol memory check (S21). As a result, if it is not “00”, the process is terminated. If it is “00”, it is determined whether or not the reserved number is “0” (S22). As a result, if the reserved number is “0”, a demo display process is performed (S23), and then the process ends. On the other hand, if the reserved number is not “0”, data “01” indicating special symbol variation time management is set in the control state flag (S24).

  When data “01” indicating special symbol variation time management is set in the control state flag, pre-processing for jackpot determination is performed (S25). At this time, the main CPU 31 reads the high probability flag, selects the jackpot determination table, and searches the selected jackpot determination table using the jackpot determination random number.

  Then, based on the result of searching the big hit determination table in the big hit determination pre-processing, it is determined whether or not the big hit is determined as the big hit determination (S26). As a result, if it is a big hit, a big hit symbol determining process is performed (S27), and if it is not a big hit, a missing symbol determining process is performed (S28).

  In the big-hit symbol determination process, it is determined whether it is a probable big-hit or normal big-hit from the big-hit symbol random value extracted when the game ball wins the start winning opening 9, and when it is normal big-hit, FIG. From the special symbol determination table, “H” is selected as the special symbol and the symbol command z1 is selected and output to the sub-control circuit 40. On the other hand, when it is a probable big hit, “F” is selected as the special symbol and the symbol command z2 is selected, and the symbol command is set in the transmission buffer provided in the RAM 33.

  Further, in the off symbol determination process, “−” is selected as the special symbol from the special symbol determination table shown in FIG. 8 and the symbol command z0 is selected, and the symbol command is set in the transmission buffer provided in the RAM 33.

  Thereafter, the main CPU 31 determines a variation pattern (S29). In determining the variation pattern, a variation pattern table (not shown) is used, one random value is obtained from a plurality of random values, for example, 0 to 99, and a plurality of variation pattern commands are obtained by referring to the result of the jackpot determination in step S26. One of these is selected and determined. The main CPU 31 sets the determined variation pattern command in the transmission buffer provided in the RAM 33.

  Thereafter, the variation time corresponding to the determined variation pattern is set in the waiting time timer (t) (S30). Then, the storage area used for the current variation is cleared (S31), and the special symbol storage check process ends.

  Returning to the flow shown in FIG. 13, when the special symbol storage check process is completed, the special symbol variation time management process is performed (S13). In the special symbol change time management process, the symbol display process is performed when the control state flag is “01” indicating the special symbol change time management. In the symbol display process, a display process for displaying the special symbol on the special symbol display device 16b in a pattern corresponding to the variation pattern determined in step S29 is performed. After that, when the waiting time timer (t) of the variation time determined in step S30 becomes 0, the data “02” indicating the special symbol fixed stop display time management is set in the control state flag, and the special symbol variation time is fixed. The waiting time after determination (for example, 1 second) corresponding to the time after the setting is set in the waiting time timer (t). Thus, the special symbol variation time management process is ended.

  When the special symbol variation time management process is completed, the special symbol fixed stop display time management process is performed (S14). In the special symbol fixed stop display time management process, the stop display process is performed when the control state flag is the value “02” indicating the special symbol fixed stop time management. In the stop display process, a process of stopping and displaying the symbol determined in step S27 or step S28 shown in FIG. 14 on the special symbol display device 16b is performed. Thereafter, when the post-decision waiting time timer (t) determined in the special symbol variation time management process becomes 0, a control flag based on the result of the jackpot determination in step S26 is set. Specifically, when the result of the big hit determination is a big hit, data “03” indicating the big hit start interval management is set in the control state flag, and the time corresponding to the big hit start interval is set in the waiting time timer (t). set. On the other hand, if the result of the big hit determination is out of place, data “04” indicating the end of the special symbol game is set in the control state flag, and the process is ended.

  When the special symbol fixed stop display time management process is completed, the big hit start interval management process is performed (S15). In the big hit start interval management process, when the control state flag is data “03” indicating the big hit start interval management, the big hit start corresponding time set in step S13 is waited. In order to open the winning opening, the variables positioned in the main RAM 33 are updated based on the data read from the main ROM 32. Further, the main CPU 31 sets the data “04” indicating that the special winning opening is being opened in the control state flag, and sets the open upper limit time (for example, 30 seconds) in the special winning opening time timer.

  Furthermore, a special winning opening opening process is performed (S16). In the special prize opening opening process, the following process is performed when the control status flag is data “04” indicating that the special prize opening is open, and if it is not “04”, it is not performed. That is, the main CPU 31 closes the big prize opening when the big prize opening prize counter is 10 or more, or when the opening upper limit time has passed (the big prize opening time timer is “0”). The variable located in the main RAM 33 is updated. Further, the main CPU 31 sets data “05” indicating that the control state flag indicates the residual ball monitoring in the winning prize mouth, sets the monitoring time (for example, 1 second) in the winning winning mouth residual ball in the waiting time timer, and remains in the winning winning mouth. After the sphere monitoring time has elapsed, it is set to proceed to the next step. If it is not determined that either is satisfied, the process proceeds to the next step without executing the above-described processing.

  Subsequently, a special winning opening residual ball monitoring process is performed (S17). In the special winning opening residual ball monitoring process, the following processing is performed when the control state flag is data “05” indicating the special winning opening residual ball monitoring. The main CPU 31 determines whether or not the special winning opening opening number counter is 15 or more (final round) when the special winning opening residual ball monitoring time has elapsed, and when it is the final round, data indicating the big hit end interval. “07” is set in the control state flag, and the time corresponding to the big hit end interval (hereinafter referred to as “big hit end corresponding time”) is set in the waiting time timer. Thus, after the jackpot end corresponding time has elapsed, the jackpot interval processing is set to be executed. If neither of them is satisfied, data “06” indicating the management of reopening waiting time for the big winning opening is set in the control state flag. Further, the time corresponding to the interval between rounds is set in the waiting time timer, and after the waiting time has elapsed, the waiting time management process before reopening the big winning opening in step S16 is set.

  Subsequently, a waiting time management process before reopening the big winning opening is performed (S18). In the waiting time management process before the big winning opening reopening, when the control state flag is data “06” indicating the waiting time management process before the big winning opening reopening, the process waits for the time corresponding to the interval between rounds. When the time corresponding to the interval between rounds has elapsed, the main CPU 31 updates the special winning opening opening number counter by adding “1”, and sets the data “04” indicating that the special winning opening is open to the control state flag. The upper opening limit time (for example, 30 seconds) is set in the big prize opening time timer. Further, in the waiting time management process before reopening the big winning opening, a main winning opening release command of the sub control circuit 40 is transmitted from the main control circuit 30.

  Then, a jackpot end interval process is performed (S19). In the big hit end interval process, as shown in FIG. 15, it is determined whether or not the control state flag is “07” indicating the big hit end interval (S32). If it is not “07”, the big hit end interval process is ended. If the control flag is “07”, it is determined whether or not the waiting time timer (t) corresponding to the big hit end interval is “0”. If not, the big hit end interval process is finished (S33). . If the waiting time timer (t) is “0”, “08” indicating the end of the special symbol game is set in the control state flag (S34).

  Next, it is determined whether or not the winning combination has been won (whether the jackpot symbol selected in step 27 is a probability variation jackpot symbol or a normal jackpot symbol) (S35). As a result, if the probability change is won, the probability change game state command for shifting to the probability change game state after the big hit ends is set in the transmission buffer, and the high probability flag is set (S36). On the other hand, if the winning is not successful, the short-time gaming state command for shifting to the short-time gaming state after the big hit ends is set in the transmission buffer (S37), and the short-time number counter is set to a predetermined number, for example, 100 (S38). . In this way, the jackpot end interval process is completed.

  Returning to FIG. 13, when the jackpot end interval process is completed, a special symbol game end process is performed (S20). The following processing is performed when the control state flag is data “08” indicating the special symbol game end processing, and if it is not “08”, the processing is not performed. The main CPU 31 updates the data indicating the number of holds to be decreased by “1”, and sequentially shifts the count values of the jackpot determination random number counter and the jackpot stop mode selection random number counter. When step S20 ends, the special symbol control process of step S2 ends.

  When the special symbol control process is completed in this way, the process returns to FIG. 12, and the normal symbol control process is performed (S3). In the normal symbol control process, control related to the normal symbol displayed on the special symbol display device 16b is performed. When the normal symbol control process is started, the normal symbol control state flag is read, and the fluctuation time of the normal symbol and the mode of the stopped normal symbol are monitored according to the flag. And when the mode of the normal symbol is a predetermined mode, the variable indicating the opening and closing of the blade 9a is stored in the main RAM 33, and the normal symbol control process is terminated.

  Thereafter, random number update processing is performed (S4). 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, the process returns to step S2 and the repeat routine is repeated.

(System timer interrupt processing procedure)
In the main control circuit 30, the random number used in the main control process is updated mainly on the condition that the interrupt permission flag is set together with the main control process described above. The system timer interrupt process for interrupting the control process is executed according to the flowchart shown in FIG. Hereinafter, the procedure of the system timer interrupt process will be described with reference to the flowchart shown in FIG.

  As shown in FIG. 16, when the pachinko gaming machine 1 starts the system timer interrupt process, the program address data and the like being executed in the main control process stored in the storage area (register) in the memory are temporarily saved. (S41), random number update processing is performed (S42). In the random number update process, the main CPU 31 performs a process of updating the jackpot determination random number value or the jackpot symbol determination random number value. When the random number update processing is completed, switch input detection processing is performed (S43).

  In the switch input detection process, a prize ball related switch input check, a special symbol game related switch input check, and a normal symbol related switch input check are performed. In the special symbol game related switch input check, the output of the detection signal of each of the count switch 11CS and the start winning opening switch 9S is checked, and if there is an output from the starting winning opening switch 9S, the start memory number counter is less than 4 The following processing is performed. In addition, when the starting memory number counter is 4 or more, a random number is stored as starting memory up to 4 when a game ball is won in the starting winning opening 9 during variable display or jackpot, so the following processing is performed. Not performed.

  Then, the jackpot determination random number value is extracted from the jackpot determination random number counter, and the jackpot symbol random number value is extracted from the jackpot symbol determination random number counter. The extracted jackpot determination random number value and jackpot symbol random number value are stored in the main RAM 33, and these random numbers are used for the jackpot determination and jackpot symbol determination process in steps S26 to S27. This completes the switch input detection process.

  When the switch input detection process is completed, a timer update process is performed (S44). In the timer update process, the waiting time timer is updated. After the timer update process, a game information data generation process is performed (S45). In the game information data generation process, an output signal from the pachinko gaming machine 1 to a hall computer (not shown) is generated. Then, output processing is performed by controlling ON / OFF of each solenoid and motor based on the data stored in the main RAM 33 (S46), and then command output for outputting various commands is performed (S47). In command output, various commands such as symbol commands and variation pattern commands set in the transmission buffer are transmitted from the command output port 35 to the sub-control circuit 40.

  Subsequently, a lamp control process (S48) and a payout process (S49) are performed. In the lamp control process, a lamp blinking command is output to the sub-control circuit 40. In the 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. After the payout process is completed, the saved program address data register of the main control process is restored (S50), and the main control process is resumed from the point where it was interrupted (saved). Thereafter, the variables, flags, etc. of the main RAM 33 are updated to permit interrupts (S51), and 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 performs a symbol control, a sound control, a lamp control, and the like by receiving a command transmitted from the main control circuit 30. FIG. 17 is a flowchart showing a procedure of sub control processing repeatedly executed by the sub control circuit 40.

  As shown in FIG. 17, the sub CPU 41 first performs a predetermined initialization process (S61), and then performs a random number update process (S62). Subsequently, command analysis control processing of various commands transmitted from the main control circuit 30 and stored in the reception buffer is performed (S63), and display control processing is performed based on the result of the command analysis control processing (S64). The command analysis control process and the display control process will be described in detail later.

  Thereafter, a sound control process is performed (S65). In the sound control process, a sound control process related to the sound generated from the speakers 18L and 18R is performed based on a command from the main control circuit 30. In this sound control process, the sound source IC 61 reads the 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.

  Subsequently, a lamp control process is performed (S66). In the lamp control process, a lamp control process related to blinking of the decorative lamps 19L and 19R is executed based on a command from the main control circuit 30. 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. Thereafter, step S62 to step S66 are repeatedly executed.

  Next, processing when a command transmitted from the main control circuit 30 is received will be described. As shown in FIG. 18, when the sub control circuit 40 receives a command transmitted from the main control circuit 30, first, the protection register is saved (S71). Next, the command input by the transmission from the main control circuit 30 is stored in the reception buffer in the sub RAM 43 (S72). Subsequently, the register is restored (S73). Thus, the process upon receiving the command ends.

  Next, the command analysis control process shown in step S63 of FIG. 17 will be described. FIG. 19 is a flowchart showing the procedure of the command analysis control process. As shown in FIG. 19, in the command analysis control process, first, the sub-control circuit 40 determines whether or not a symbol command has been received from the main control circuit 30 (S81). Specifically, it is confirmed whether the symbol command is stored in the reception buffer. As a result, if a symbol command has been received, a decorative symbol determination process is performed (S82).

  In the decorative symbol determination process, the symbol determination table shown in FIGS. 9 to 11 is selected on the basis of the symbol command transmitted from the main control circuit 30 and is generated by a random number generation program stored in the sub ROM 42. A random value of 1 is acquired from the random number, and the decorative design is determined with reference to the design determination table. Here, when the symbol command transmitted from the main control circuit 30 is z0, a random number value is separately acquired for each of the left middle right symbol, and each decorative symbol is selected and determined. Here, when the same type of symbol is selected as the left middle right symbol, the random number is acquired again. In this way, the off-line decorative design is determined.

  Further, when the symbol command transmitted from the main control circuit 30 is z1, the left symbol determination table of the normal jackpot decoration symbol determination table shown in FIG. 10A is based on the acquired random number value. The left symbol of the decorative symbol is determined with reference to the reference symbol. Next, based on the separately acquired random number and the previously determined left symbol, the middle symbol is determined with reference to the middle symbol determination table shown in FIG. Subsequently, the right symbol is determined with reference to the right symbol determination table shown in FIG. 10C based on the separately acquired random number and the previously determined left middle symbol. In this way, a normal jackpot decorative design is determined.

  When the symbol command transmitted from the main control circuit is z2, on the basis of the obtained random number value, refer to the left symbol determination table of the probability variation big hit decoration symbol determination table shown in FIG. The left design of the decorative design is determined. Next, based on the separately acquired random number and the previously determined left symbol, the middle symbol is determined with reference to the middle symbol determination table shown in FIG. Subsequently, the right symbol is determined with reference to the right symbol determining table shown in FIG. 11C based on the separately acquired random number and the previously determined left middle symbol. In this way, the probable big hit decoration symbol is determined.

  On the other hand, if the symbol command has not been received, the process proceeds to the next step S83 without performing the decorative symbol determination process.

  When the decoration symbol determination process is completed, it is determined whether or not a variation pattern command is received (S83). As a result, if it is determined that the variation pattern command has been received, the decorative symbol determined by the decorative symbol determining process includes a special symbol element “triple 7” as the symbol symbol as the left symbol DL or the middle symbol DC. It is determined whether or not it is a symbol (special jackpot identification symbol) (S84).

  As a result, if it is determined that the decorative symbol is a special symbol, a special variation effect pattern corresponding to the variation pattern command transmitted from the main control circuit 30 is set (S85). When this special variation effect pattern is selected, one of the symbol commands z1 and z2 when winning the big hit lottery is surely transmitted. For this reason, when the special variation effect pattern is set, the big prize opening is always opened. However, if the special fluctuation effect pattern is selected, the fluctuation will occur even after the special prize opening is opened. The production pattern continues. After setting the special variation effect pattern corresponding to the variation pattern command, the variation time timer corresponding to the variation pattern command is set (S86). Thus, the command analysis control process ends. Here, the “variable effect pattern” refers to a pattern in which the type, size, coordinates, etc. of each symbol element corresponding to each unit time (one frame) until each symbol element is stopped and displayed are defined. . Further, the “variation time corresponding to the variation pattern command” here refers to the variation time of the special symbol in step S30 shown in FIG. 14, and when the variation time has elapsed, the big hit lottery is won. In this case, the game is shifted to the big hit gaming state (see steps S13 and S14 in FIG. 13).

  On the other hand, if it is determined that the decorative symbol is not a special symbol, a variation effect pattern corresponding to the variation pattern command transmitted from the main control circuit is set (S87). This variation effect pattern is completed before the special winning opening is opened because no special symbol is selected. Then, the variation time corresponding to the variation pattern command is set (S88). Thus, the command analysis control process ends.

  If it is determined in step S83 that no variation pattern command has been received, it is determined whether or not a jackpot release command has been received (S89). As a result, it has been determined that a jackpot release command has not been received. In this case, the process corresponding to the other received command is executed (S90), and the command analysis control process is terminated. On the other hand, if it is determined that the jackpot release command has been received, round number measurement processing is performed (S91). In the round number measurement process, the number of jackpot opening commands transmitted from the main control circuit 30 is counted, and the number of times the jackpot opening is opened in the jackpot gaming state is measured. After the round number measurement processing is completed, the final symbol stop time is set when the planned number of rounds (8 rounds in this embodiment) is reached (S92), and the command analysis control processing is terminated. That is, after the scheduled number of rounds has been reached, a final symbol stop time subtraction process (so-called countdown) is performed by a timer update process in a timer interrupt process (not shown).

  Next, the display control process in step S64 of the sub control process shown in FIG. 17 will be described. FIG. 20 is a flowchart illustrating the procedure of the display control process. As shown in FIG. 20, in the display control process, first, a symbol display control process is performed (S95), and then a background display control process is performed (S96). This completes the display control process.

  Next, the symbol display control process in step S95 will be described. FIG. 21 is a flowchart showing the procedure of the symbol display control process. As shown in FIG. 21, in the symbol display control process, it is determined whether or not a variation effect pattern is set (S101). As a result, when the variation effect pattern is not set, the symbol display control process is terminated. On the other hand, if the variation effect pattern is set, it is determined whether or not the set variation effect pattern is a special variation effect pattern (S102). Whether or not it is a special variation effect pattern is determined by whether or not the special symbol element “triple 7” is included in at least one of the left symbol and the middle symbol.

  As a result, when it is determined that the variation pattern is a special variation effect pattern, it is determined whether the variation time timer is 0, in other words, whether the variation time has elapsed (S103). If the variation time timer is not 0, variation display control according to the special variation effect pattern is performed (S104), and the symbol display control process is terminated. On the other hand, when the variation time timer is 0, a part of the symbol elements including the special symbol element among the special symbols is controlled to be stopped (S105). The stop control of some of the symbol elements including the special symbol element is different depending on the position where the special symbol element “triple 7” is displayed. Specifically, when the special symbol element “triple 7” is stopped and displayed on the left symbol, only the special symbol element “triple 7” of the left symbol is stopped and displayed, and the middle symbol element that is another symbol element And the right symbol element remains variably displayed.

  In addition, when the left symbol is any of the numerical symbol elements “0” to “9” other than the special symbol element “triple 7” and the middle symbol is the special symbol element “triple 7”, the left symbol The symbol element and the middle symbol element are stopped and the right symbol element remains variably displayed.

  In this way, when a part of the symbol elements including the special symbol elements are controlled to stop or the variation display effect according to the special variation effect pattern is performed, the big hit round counted in the round counting process in step S91 is a predetermined number of rounds. In the present embodiment, it is determined whether or not it has reached eight times (S106). As a result, when it is determined that the number of rounds has not reached eight, variable display control is performed for symbol elements that are not stopped (S107).

  On the other hand, if it is determined that the number of rounds has reached eight, it is determined whether or not the final symbol stop time set in step S92 has become zero (S108). The final symbol stop time is subtracted in a timer update process in a timer interrupt process (not shown). As a result, when it is determined that the final symbol stop time is not 0, the variable display control of the symbol elements not stopped and displayed is continued (S107). On the other hand, when it is determined that the final symbol stop time is 0, the fixed stop control is performed to stop all the symbol elements including the symbol elements for which the variable display is continued (S109). Then, the variation effect pattern is cleared (S110), and the symbol display control process is terminated.

  If it is determined in step S102 that it is not a special variation effect pattern, it is determined whether or not the variation time timer is 0 (S111). As a result, when it is determined that the variation time timer is not 0, variation display control corresponding to each variation effect pattern is performed (S112), and the symbol display control process is terminated. On the other hand, if it is determined that the variation time timer is 0, a fixed stop control is performed to stop all symbol elements (S113), the variation effect pattern is cleared (S114), and the symbol display control process is terminated. To do.

  Next, the flow of the special symbol game will be described. In the special symbol game, when the game ball wins the start winning port 9 and the start winning port switch 9S outputs the detection signal of the game ball to the main control circuit 30, the main control circuit 30 performs a big hit lottery. Based on the lottery result, main control circuit 30 selects a symbol command from the special symbol determination table shown in FIG. 8, and also selects a variation pattern command from a variation pattern table (not shown). The main control circuit 30 transmits the selected symbol command and variation pattern command to the sub control circuit 40, respectively. The sub-control circuit 40 determines a decorative symbol based on the received symbol command, and also determines a variation effect pattern from the determined decorative symbol and the received variation pattern table.

  In the display area 16a, the symbol elements DL, DC, DR are stopped and displayed before the game ball wins the start winning opening 9. Further, in the special symbol display device 16b shown in FIG. 4, the special symbol J is stopped and displayed. In this state, when a game ball wins the start winning opening 9, the symbol elements DL, DC, DR and the special symbol J start to be displayed in a variable manner as shown in FIG.

  Then, after a predetermined fluctuation time elapses, the left symbol DL is stopped and displayed, then the middle symbol DC is stopped and displayed, and the right symbol DR is stopped and displayed. The decorative symbol D includes a special decorative symbol which is a special jackpot identifying symbol including the special symbol element “triple 7” as the symbol symbol as the left symbol DL or the middle symbol DC, and does not include the special symbol element or the left symbol DL In addition, the middle symbol DC is not a special symbol element, and there is a normal decorative symbol which is “triple 7” only in the right symbol DR, and the timing of stop display is different between the special decorative symbol and the normal decorative symbol.

  First, the stop timing of the normal decorative symbols will be described. First, when a numerical symbol element other than the special symbol element “triple 7” is stopped and displayed as the left symbol DL, the middle symbol is subsequently stopped and displayed after a predetermined fluctuation time has elapsed. At this time, when different numerical symbol elements are stopped and displayed as the left symbol DL and the middle symbol DC, the right symbol DR is stopped and displayed after a predetermined fluctuation time has elapsed, and there is no transition to the big hit gaming state, Informs the player that the normal gaming state will continue. In addition, when the same numerical symbol element is stopped and displayed as the left symbol DL and the middle symbol DC, the same numerical symbol element is further stopped and displayed in the right symbol DR, so that the transition to the big hit gaming state is notified. It becomes a so-called reach state. By reaching this reach state, it is possible to enhance the player's expectation for the big hit gaming state.

  Thereafter, when the number symbol elements stopped and displayed as the left symbol DL and the middle symbol DC are stopped and displayed on the right symbol DR, the transition to the big hit gaming state is confirmed. On the other hand, when a numerical symbol element different from the numerical symbol elements stopped and displayed as the left symbol DL and the middle symbol DC is stopped and displayed on the right symbol DR, there is no transition to the big hit gaming state, and the normal gaming state continues.

  Subsequently, the stop timing of the special decorative symbols will be described. First, as shown in FIG. 22 (b), when the special symbol element “triple 7” is stopped and displayed as the left symbol DL, it is a big hit at that time without waiting for the stop display of the middle symbol DC and the right symbol DR. Transition to the gaming state is confirmed. At the same time, in the background image, a person with a surprised expression due to the display of “triple 7” is displayed comically. As described above, since the game state is shifted to the big hit game state before all the symbol elements are stopped and displayed, the shift to the big hit game state can be diversified, and the interest of the game can be improved.

  Thus, when the special symbol element “triple 7” is stopped and displayed as the left symbol DL, it shifts to the big hit gaming state, and the big winning opening shown in FIG. 4 is opened. Further, as shown in FIG. 22 (c), in order to notify the transition to the big hit gaming state, the characters “big hit” are displayed on the background image. Further, even after the transition to the big hit gaming state, the middle symbol DC and the right symbol DR continue to be displayed in a variable manner.

  Thereafter, when the round of the big hit gaming state progresses and reaches the eighth round, as shown in FIG. 23 (a), the text “Is it surely changed?” Is displayed on the background screen. Here, the middle symbol DC and the right symbol DR are still displayed in a variable manner. Thereafter, the middle symbol DC is stopped and displayed, and then the right symbol DR is stopped and displayed. At this time, as shown in FIG. 23 (b), both of the middle symbol DC and the right symbol DR are numerical symbol elements, and in the example shown in FIG. 23 (b), the numerical symbol elements “6” and “7” are stopped. In this case, since only one special symbol element “triple 7” is stopped and displayed on the decorative symbol D, it is usually a big hit. In this case, the characters “sorry ... .. normal jackpot” are displayed in the background image.

  On the other hand, if the special symbol element “triple 7” is stopped and displayed on one or both of the middle symbol DC and the right symbol DR, the probability variation big hit is obtained. In the example shown in FIG. 23C, the numerical symbol element “7” is stopped and displayed on the middle symbol DC, and the special symbol-related symbol element “triple 7” is stopped and displayed on the right symbol DR. The message “Probable big hit!” Is displayed. In this way, since the probability change big hit is notified after shifting to the jackpot gaming state, it is possible to give a sense of expectation of transition to the probability changing gaming state and improve the interest of the game.

  In addition, the middle symbol DC and the right symbol DR are stopped and displayed in order with time. First, when the middle symbol is stopped and displayed, the expectation for probability variation big hit by the stop display of the special symbol related symbol element “triple 7” is displayed. It can make you feel. Even if the special symbol related symbol element “triple 7” is not stopped and displayed in the middle symbol DC here, the special symbol related symbol element “triple 7” is stopped in the right symbol DR to be stopped and displayed next. By being displayed, it becomes a probable big hit. Therefore, it is possible to sufficiently keep the expectation for the probable big hit.

  Further, when the special symbol is displayed as the decorative symbol D, the special symbol element “triple 7” is not stopped and displayed as the left symbol DL, and any of the numerical symbols “0” to “9” is stopped and displayed. In some cases, the special symbol element “triple 7” is stopped and displayed as the middle symbol DC. In this case, after the middle symbol DC is stopped and displayed, before the right symbol DR is stopped and displayed, the game shifts to the big hit gaming state, and the right symbol DR enters the big hit gaming state with the variable display being continued. . Thereafter, whether the big hit is a probable big hit or a normal big hit is determined by the stop display mode of the right symbol DR in the eighth round.

  As described above, as a mode for notifying the transition to the big hit gaming state, in addition to the mode in which the decorative symbol D is stopped and displayed on the three symbols, there is a mode in which the special symbol element “triple 7” is stopped and displayed. It is possible to diversify the transition mode. Moreover, in the case where the special symbol element is stopped and displayed as the left symbol DR and the middle symbol DC, it is determined whether the big hit is a probable big hit or a normal big hit after the big hit gaming state is started. The expectation for a promising big hit can be sustained.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the identification symbol displayed in the display area is in the form of 1 row and 3 columns, but may be in the form of 3 rows and 3 columns. In the case of this 3 × 3 mode, the decorative symbol arrangement shown in FIG. 24 can be used. Using the decorative symbol arrangement shown in FIG. 24, three rows of symbol elements in the display area are displayed. For example, as shown in FIG. 25, when the left symbol number 15, the middle symbol number 14, and the right symbol number 6 are selected, the left symbols are “7”, “7”, “7” in order from the top. A symbol is displayed. As the middle symbols, the symbols “·”, “7”, and “7” are displayed in order from the top, and as the right symbols, the symbols “7”, “7”, and “•” are displayed in order from the top.

  In this 3 rows and 3 columns display mode, the so-called 5-line system is used. Upper left-middle upper-upper right, left middle-middle middle-right middle, lower left-middle lower-lower right, upper left-middle middle-lower right When the same numerical symbol is stopped and displayed in any of the five lines on the lower left-middle middle-upper right, a big hit gaming state is entered.

  Further, when the left symbol number 15 is selected and the numerical symbols “7”, “7”, and “7” are stopped and displayed on the left symbol in order from the top, “triple 7” is stopped and displayed in the above embodiment. As with the case, the transition to the big hit gaming state at that time is determined. Further, the numerical symbols including “7” are also stopped and displayed in the middle symbol and the right symbol. At this time, if “7” “7” “7” is stopped and displayed on two or more of the above five lines, it is a probable big hit and “7” “7” “7” is stopped only on one line. When displayed, it is usually a big hit. Such an aspect can also be adopted.

  Further, in the above embodiment, an example in which the probable big hit game state and the normal big hit game state have been described as the big hit game state, but instead of this, the short-time big hit state and the normal big hit game state are used. It can also be set as the aspect which has. In the short-time and big hit game state, after the short and big hit game state ends, the special symbol variation display time becomes shorter than the variation display time in the normal game state. Further, in the normal big hit gaming state, after the normal big hit gaming state ends, the normal gaming state is entered. The short-time gaming state here can be either an aspect that continues until the next big hit or an aspect that continues until a predetermined number of lotteries. In this way, it is possible to provide a mode in which a big hit gaming state having different advantages after the big hit gaming state is provided.

  Furthermore, it is also possible to set the probability variation big hit gaming state and the short time big hit gaming state in combination. For example, if the promiscuous big hit gaming state continues and then the normal big hit gaming state is reached, then it becomes the short time big hit gaming state, and if the normal big hit gaming state occurs independently, then the normal big hit gaming state is entered. It can be set as an aspect. In addition, in the promising big hit game state, the number of times of opening of the big winning opening is increased, and in the normal big hit, the number of times of opening of the big winning opening is reduced, so that the advantage of the gaming state can be made different. In addition, the difference between the opening conditions of these and the special prize opening, the difference in the number of winning prizes to the big prize opening, and the like can also be set.

  Moreover, in the said embodiment, although there is no difference in the advantage of a big hit game state, it can also be set as the aspect which makes a difference in the advantage of a big hit game state. Specifically, by differentiating at least one of the number of times of opening the grand prize opening, the opening time of the big prize opening, the number of winning prizes, the number of payout balls, and the condition for continuing the opening of the big prize opening, The advantage can be made different. Moreover, the difference in these advantages can be notified by displaying a decorative design. For example, when the special symbol is stopped and displayed in all of the left middle right, it is possible to set the aspect in which the advantage of the above condition is the highest.

  Furthermore, in the said embodiment, although a special symbol element and a special symbol related symbol element are both "triple 7", it can also be set as the aspect made different. For example, when the special symbol element is “triple 7” and the special symbol element is displayed on one of the left symbol and the middle symbol, the same number on the other of the left symbol and the middle symbol and on the right symbol When a symbol is displayed, it is a probable big hit, and when a different numerical symbol is displayed, it can be a normal big hit.
