Abstract

<P>PROBLEM TO BE SOLVED: To provide a novel game machine capable of optimizing the probability of the shift to a special presentation mode called a "mission mode", etc. from a regular presentation mode. <P>SOLUTION: When the presentation mode is shifted from the special presentation mode to the regular presentation mode, the probability of a lottery for the shift to the next special presentation mode is varied based on the number of times of variation of presentation symbols after the special presentation mode is terminated. Accordingly, the probability of occurrence of such inconvenience that the mode is immediately shifted to the next "mission mode" again after the "mission mode" is terminated, or that, on the contrary, the mode is not shifted to the "mission mode" or hardly shifted to the "mission mode" after the long-time play, can be lowered, and therefore, the probability of the shift of the presentation mode can be optimized. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a gaming machine such as a pachinko machine called a digipachi, and more particularly to a gaming machine in which a predetermined effect design is variably displayed in a predetermined variation pattern on a liquid crystal display or the like provided on a game board. Is.

  In general, many of the conventional pachinko machines called digipachi, etc. usually have a so-called “short-time function” that shortens the time of symbol variation and increases the chance of “big hit” lottery, and the probability of the next “big hit” The so-called “probability change function”, which is significantly higher than the probability of “big hit”, is installed, and after the first “big hit” is finished, it is easy to induce the next “big hit” in a row and playability Has come to greatly increase.

  On the other hand, with conventional pachinko machines equipped with such "short-time function" and "probability change function", since "big hit" tends to be continuous and a large number of prize balls tend to be paid out in a short time, The probability of “big hit” in normal times is set low (for example, about 1/400), and as a result, even if lottery is performed 1000 times or more continuously, the next “big hit” is not won. Often falls into the “hamari state”.

  For this reason, with conventional digipachi pachinko machines, in order to eliminate the boring feeling of the player in such a `` hamari state '' and the feeling of directivity of the production, the number of production pattern fluctuation patterns, reach actions, etc. can be increased, As shown in Patent Document 1 below, a special production mode different from the normal production mode called “mission mode (production)” is prepared, and the normal mission mode is changed to this “mission mode”. By switching and displaying the time (for example, 5 minutes), the variation of the production in the “Humari state” or the like is increased so as to eliminate the boring feeling and the sense of feeling of the production.

Note that a special performance mode called “mission mode” or the like as shown in Patent Document 1 is substantially effective for the player, such as the “time reduction function” or the “probability change function” as described above. Rather than showing an advantageous state, it is often one of the mere effects for enhancing game play like the change pattern of the effect pattern and the reach action.
JP 2005-168876 A

By the way, the transition from the normal mode to the “mission mode” as shown in Patent Document 1 is performed by a predetermined random number separately prepared for each “big hit” lottery performed in response to a winning of a game ball at the start opening. It is decided by the lottery method.
For this reason, immediately after the completion of a certain “mission mode” due to the so-called “probability fluctuation”, it immediately shifts to the next “mission mode”, which makes the player feel persistent. Or, conversely, there may be cases where even if a game is played for a long time, there is little or no transition to this “mission mode”.
Therefore, the present invention has been devised in order to effectively solve such problems, and the purpose thereof is the probability of transition from a normal performance mode to a special performance mode called “mission mode” or the like. A new gaming machine that can optimize the game is provided.

In order to solve the above-mentioned problem, a gaming machine according to claim 1,
A lottery means for shifting to the special effect mode for performing a lottery for shifting from the normal effect mode to the special effect mode for each lottery of the special prize that is triggered by the winning of the game ball at the start opening, and the lottery means for transferring the special effect mode A game machine having an effect symbol display means for variably displaying a predetermined effect symbol selected every lottery of the special prize by shifting to the effect mode,
When the special effect mode transition lottery means shifts from the special effect mode to the normal effect mode, the special effect mode transition lottery means goes to the next special effect mode based on the number of changes in the effect symbol of the effect symbol display means after the special effect mode ends. The transfer lottery probability is changed.

  As a result, immediately after the special performance mode called “mission mode” is completed, the system immediately shifts to the next special performance mode immediately, or vice versa. Since it is possible to reduce the probability of occurrence of unevenness or variation in the transition rate, such as no or almost no transition, it is possible to optimize the transition probability from the normal performance mode to the special performance mode.

In addition, the gaming machine of claim 2
2. The gaming machine according to claim 1, wherein the effect mode transition lottery means counts the number of changes in the effect symbol of the effect symbol display means after the end of the special effect mode, and the next special effect as the number of changes increases. The transition lottery probability is varied so that the transition probability to the mode becomes high.
This makes it difficult to move to the next special effect mode immediately after a special effect mode ends, and it becomes easier to move to the next special effect mode as the number of changes increases. It is possible to avoid the inconvenience that the transition to the production mode is not performed at all or almost.

The gaming machine according to claim 3 is:
3. The gaming machine according to claim 2, wherein the effect mode transition lottery means shifts to the next special effect mode until the number of changes in the effect symbol of the symbol display means after the end of the special effect mode reaches a predetermined number. The transition lottery probability is set so as not to occur.
As a result, immediately after a certain special effect mode is finished, the transition to the next special effect mode is stopped. Can be avoided.

The gaming machine according to claim 4 is:
4. The gaming machine according to claim 2, wherein the effect mode transition lottery means always performs the next special when the number of changes in the effect symbol of the symbol display means after the end of the special effect mode reaches a predetermined number. The transition lottery probability is set so as to shift to the production mode.
As a result, after the end of a certain special effect mode, when the number of changes of the effect symbol of the symbol display means reaches a predetermined number of times, it will always shift to the next special effect mode. Even in such a case, it is possible to avoid the inconvenience that the transition to the special effect mode is hardly or hardly.

  In short, according to the present invention, immediately after the special performance mode called “mission mode” or the like is finished, the system immediately shifts to the next special performance mode immediately, or vice versa. Since it is possible to reduce the probability of occurrence of unevenness or variation in the transition rate such that the transition to the special performance mode is almost complete, the transition probability from the normal performance mode to the special performance mode can be optimized.

Next, FIG. 3 is a block diagram showing the configuration of the control system of the gaming machine 100 of the present invention having such a configuration.
As shown in the figure, the configuration of the control system of the gaming machine 100 according to the present invention includes a main control board 200 that performs main control such as detection of a winning game ball and lottery of special prizes, and commands (controls) from the main control board 200. Command) and a composite sub-control board 300 that performs control related to various effects and the like, and prize ball payout control that mainly executes control related to payout of prize balls in response to a command (control command) from the main control board 200 A special symbol display substrate 500 that controls a special symbol display 52 that displays a special symbol, a normal symbol display substrate 50 that displays a normal symbol, a normal symbol display substrate 600 that controls an electric tulip, and the special prize state The main prize opening solenoid 700 that opens and closes the big prize opening 38 and the like, and a power supply unit 800 that supplies power to each of these boards and the like are mainly configured. .

  First, the main control board 200 includes a CPU (central processing unit) 210, a RAM (main storage device) 220, a ROM (reading storage device) 230, a timer 240, an input port 250, an output port 260 and the like through a bus 270. The CPU 210 is composed of a connected microcomputer, and the CPU 210 performs predetermined processing based on the main control program written in the ROM 220 and various information input from the input port 250, and performs control according to the processing result. A signal is output from the output port 260 to the composite sub-board 300, the prize ball payout control board 400, etc. via a control command for command.

  The input port 250 detects the winning of a game ball to the start winning prize detector (switch) 251 for detecting the winning of the game ball to the start winning opening 34 described above and the large winning opening 38 described above. Operation of the various winning opening detectors (switches) 253, the launching device 22 and the shortage of winning balls for detecting winnings to the big winning opening winning detector (switch) 252, the general winning opening 48, the normal symbol starting winning opening 35, etc. Are detected, and signals detected by these detectors 251, 252, 253, 254 are appropriately input to the main control board 200 via the input port 250. It is like that.

  Next, as shown in FIG. 4, the composite sub-control board 300 includes a control command receiving unit 301, a control command analyzing unit 302, a control command transmitting unit 303, a special effect mode transition lottery unit 304, and a transition ratio table 305. And the normal effect mode transition processing unit 306, and as will be described in detail later, based on a control command transmitted from the main control board 200 side, the illumination control board 310 and the effect symbol display board 320 The control commands and audio signals are transmitted to the speaker 42 and the like, so that the control mainly related to the production is performed in a composite manner.

  That is, the control command receiving unit 301 mainly monitors the presence / absence of a control command transmitted from the main control board 200 side, and mainly provides a function of receiving a control command when it is transmitted. In addition, the control command analysis unit 302 mainly provides a function of analyzing the content and type of the control command received by the control command receiving unit 301 and relaying it to the control command transmitting unit 303 and the like.

Then, the control command transmission unit 303 converts a predetermined control command sent from the control command analysis unit 302, the special effect mode transition lottery unit 304, the normal effect mode transition processing unit 306, or the like into an audio signal or the like. A function of transmitting to a predetermined board set for each control command is mainly provided.
That is, a variation pattern command related to a production symbol or the like, a production mode transition command described later, etc. are on the production symbol display board 320 side, a command related to electrical decoration is on the electrical decoration control board 310 side, and a command related to voice is a predetermined audio signal. It is controlled to be transmitted to the speaker 42 and the like.

5 and 6 show examples of various control commands transmitted / received among the main control board 200, the composite sub-control board 300, the effect symbol display board 320, and the like.
As shown in FIG. 5, this control command indicates a mode (MODE) that is 1-byte digital data that is an identifier for identifying a normal command classification (function), and the contents of the control command to be executed. For example, if the command is “B1H01H” which is a command related to “designation of design”, “B1H” in all stages is a classification of control commands. This is an identifier for identifying (effect design), and indicates that the subsequent stage “01H” is the content of the control command (designated effect design) to be executed.

  Further, in transmitting such a control command “B1H01H” to the effect symbol display board 320, the composite sub-control board 300, as shown in FIG. 6, generates a strobe signal (DUSTB) generated by itself when the command changes. First, the mode data is output in response to the first rising edge, and then the next event data is output in response to the second rising edge of the strobe signal (DUSTB).

Then, the effect symbol display board 320 or the like (the CPU) that has received such a control command generates an interrupt in response to the input of the strobe signal (DUSTB), and the control command is executed by the interrupt processing. It has become.
Next, the special effect mode transition lottery unit 304 shown in FIG. 4 changes the effect mode displayed on the effect symbol display unit 30 from the normal effect mode to the special effect mode (hereinafter referred to as “mission mode” as appropriate). Processing related to transfer lottery and the like is performed, and specific processing will be described in detail later.

  Here, the “normal effect mode” in the present embodiment is, for example, an effect that is variably displayed on the screen of the effect symbol display 30 in a conventional digipachi pachinko machine as shown in FIGS. The state is the same as the effect pattern of the symbol, and the “special effect mode (mission mode)” is a message (mission mission) that specifies the effect symbols that are variably displayed on the screen of the effect symbol display 30 or a combination thereof. ) And its transition time are displayed on the screen of the effect symbol display 30, and when the effect symbol designated within the predetermined time is displayed on the effect symbol display 30, it is regarded as “big hit”. Directing.

That is, FIG. 7 shows an example of a variation pattern at the time of “losing” in the “normal effect mode”.
As shown in the figure, the fluctuation pattern at the time of “losing” in the “normal effect mode” is a state in which three front stop effect symbols (“456”) are stopped and displayed on the screen of the effect symbol display 30. When the next lottery is performed from (1), these three front stop effect symbols (“456”) start to fluctuate so as to move downward (2). After the first effect symbol “6” stops (3), the second second effect symbol “6” on the right side stops (4) and finally the third third effect symbol “5” stops ( 5), the fact that the lottery is “losing” is displayed by a combination of three effect symbols.

Then, when the next lottery is further performed from the state of (5), it returns to the state of (2) again, and the effect symbols are stopped one after another with the same variation pattern, and the lottery result is used as a combination of effect symbols. To display.
FIG. 8 shows an example of a variation pattern with a so-called reach action among the variation patterns at the time of “big hit” in the “normal effect mode”.

  As shown in the figure, from the previous stop effect symbol (1) to the second effect symbol stop (4) is the same as the variation pattern at the time of “losing”, but the first effect symbol and the second effect symbol are the same effect. When the symbols are arranged in the same pattern, as shown in FIG. 5 (5), the first effect symbol and the second effect symbol are displayed in a slightly deformed manner so that the center third effect symbol is emphasized. As shown in FIGS. (6) to (10), the third third effect symbol is changed to different effect symbols one after another in such a manner that the center third effect symbol is vertically divided.

  Then, as shown in the screen on the left side of FIG. 11 (11), when the third effect symbol at the center finally stops at the same effect symbol as the first effect symbol and the second effect symbol, “big hit” is confirmed. Then, the jackpot variation pattern starts. On the contrary, as shown in the screen on the right side of FIG. 11 (11), the center third effect symbol finally becomes the first effect symbol and the second effect symbol. When stopping at the same effect design, “losing” is confirmed and the process proceeds to the next variation pattern.

On the other hand, FIG. 9 and FIG. 10 show an example of the screen display of the effect symbol display 30 in the “special effect mode (mission mode)”.
First, as shown in FIG. 9 (1), when the next change is started from the state of the previous stop effect pattern in the normal effect mode, the special effect mode is simultaneously entered as shown in FIG. A transition lottery is performed, and when the lottery is won, a message (characters) such as “mission occurrence” is cut-in displayed on the screen of the production symbol display 30, and then the specific contents of the mission (for example, the mission) As shown in FIG. 3 (3), characters such as “Leach with the symbol“ 1 ”within 3 minutes” are displayed.

  After the display, as shown in FIG. 4 (4), the characters “Mission”, which is a display indicating that the special effect mode is displayed on the upper and lower sides of the effect symbol display 30, respectively, and the elapsed time “ The characters “Time: 2:45” are displayed in a countdown manner, and a predetermined effect symbol is variably displayed one after another for each lottery as in the normal effect mode.

After that, as shown in FIG. 5 (5), if the reach is achieved with the specified design (in this case, “1”) in the mission mode production, the mission is considered successful and at this point “ ”Is confirmed, and then a message indicating that the mission has been successful is displayed (successful mission) as shown in FIG. 6 (6), and the third effect symbol is forcibly aligned with the same symbol and the“ big hit ”state is displayed. After that, it will shift to a normal jackpot production.
Even in the “special effect mode (mission mode)”, there may be three same effect symbols other than the specified effect symbol. In this case, the “big hit” is set as in the normal effect mode. After that, after displaying the “big hit” state, the process shifts to a normal big hit effect.

FIG. 10 shows an example in which effect symbols other than the effect symbols specified in the “special effect mode (mission mode)” are prepared in this way.
As shown in FIGS. (1) to (3), after winning the lottery for shifting from the normal performance mode to the mission mode and displaying the contents and time of the mission, as shown in FIG. After reaching the reach state with an effect symbol (for example, “4”) different from the effect symbol specified at the time of a certain change, “losing” is confirmed when the third effect symbol is stopped at an effect symbol (for example, “5”). However, when the third effect symbol stops at the same effect symbol (“4”), “big hit” is confirmed, and after that, the “big hit” state is displayed and then the normal big hit effect is shifted. .

  That is, as will be described later, when a variation command corresponding to a jackpot is transmitted from the main control board 100 during this mission mode, the second effect symbol is changed to the first effect symbol in order to make the mission appear to be successful. In this case, if an effect symbol different from the effect symbol specified in the mission mode is selected, the second effect symbol and the third effect symbol are displayed. By forcibly displaying the symbols in accordance with the first effect symbols, three effect symbols different from the designated effect symbols are arranged to display the “hit” state.

  Next, the transition ratio table 305 shown in FIG. 4 shows the transition lottery ratio from the normal effect mode to the special effect mode (mission mode) based on the number of changes in the effect symbol after the end of the special effect mode (the number of special prize lotteries). The special effect mode transition lottery unit 304 is defined in accordance with the transition lottery ratio described in the transition ratio table 305 and changes from the normal effect mode to the special effect mode (mission mode) for each change (special prize lottery). A lottery process for shifting to is performed.

FIG. 11 shows an example of the data structure of the migration ratio table 305.
In the transition ratio table 305 shown in the figure, when the number of fluctuations after the end of the mission mode is “0 to 50”, the transition (rush) lottery ratio to the next mission mode is “0/100”. The next mission mode transition (entry) lottery ratio at “51 to 150” times is “2/100”, and the next mission mode transition (entry) lottery ratio when the number of fluctuations is “151 to 250” times. Is “5/100”, and when the number of fluctuations reaches “251”, the lottery ratio for the next mission mode transition (entry) is “100/100”.

  That is, when the number of changes after the end of the mission mode is “0-50”, the mission mode transition lottery is not won, and the player always stays in the normal performance mode, but as the number of changes increases. The probability of winning the transition lottery increases, and the transition lottery ratio is such that the mission mode transition lottery is always won when the number of changes reaches “251”.

Next, when the special effect mode transition lottery unit 304 described above shifts from the normal effect mode to the mission mode, the normal effect mode transition processing unit 306 shown in FIG. Processing related to the transition to the production mode is performed, and the specific processing will be described in detail later.
Then, the effect symbol control board 320 performs control related to the effect symbol by the effect symbol display unit 30 based on the control command from the composite sub-control board 300, respectively, Based on a control command from the sub-control board 300, control relating to an indicator lamp such as lighting, blinking, or extinguishing of the lamp 40 for illumination is performed.

  It should be noted that the image data corresponding to each effect symbol and variation pattern and each effect mode as described above are stored in the effect symbol control board 320 or the ROM (not shown) of the effect symbol display 30, and this composite sub-control. Predetermined image data corresponding to each control command from the substrate 300 is read out, processed into RGB data and the like, and displayed on the screen of the effect symbol display 30.

  In addition, the composite sub-control board 300, the illumination control board 310, and the effect symbol display board 320 are also a microcomputer comprising a CPU, a RAM, a ROM, a timer, an input / output port, etc. (not shown) in the same manner as the main control board 200 described above. Each effect control is performed in accordance with each dedicated control program written in the ROM and various control commands transmitted from the main control board 200.

  Further, as shown in FIG. 3, the prize ball payout control board 400 performs control related to the launching and lending of game balls, the payout of prize balls, and the like. Controls the payout device 410 for paying out the corresponding winning ball (for example, 1 or 5 for the start winning opening 26, 10 for the general winning opening 44, 15 for the large winning opening 30, etc.) It is supposed to be.

  The main control board 200, the composite sub-control board 300, the illumination control board 310, the effect symbol display board 320, the prize ball payout control board 400, the special symbol display board 500, the normal symbol display board 600, and the big prize opening solenoid 700. And various devices controlled by them, that is, the illumination lamp 40, the speaker 42, the effect symbol display 30, the launching device 22, the payout device 410, the special symbol display device 52, the normal symbol display device 50, etc. It is designed to be operated by a direct current power source supplied from.

Next, the operation and effect of the gaming machine 100 of the present invention configured as described above will be described.
First, as shown in FIG. 2, a part of the game ball bounced into the game area 20 wins the start winning opening 34, the winning is detected by the start opening winning detector 251, and a win signal is sent to the main control board 200. When input, the main control board 200 performs a lottery of a special prize state (big hit) generated with a probability of “1/400”, for example, based on a predetermined random value for the winning.
The main control board 200 selects a predetermined effect symbol corresponding to the result of the lottery and a variation pattern for variably displaying the effect symbol based on a dedicated random number value, respectively. A variation command corresponding to the pattern is transmitted as a control command to the composite sub-control board 300 side.

  That is, in the ROM 230 of the main control board 200, as described above, for example, commands corresponding to effect symbols made up of numbers, figures, colors, etc. of “0” to “9” and special prizes performed on the main control board 200 are displayed. Commands corresponding to several to tens of types of variation patterns corresponding to the lottery result of the above are stored and stored. For example, when the lottery result of the special prize is “big hit”, the command for designating the design symbol and the above-mentioned If the command corresponding to the variation pattern including the reach action etc. is selected, or if the lottery result of the special prize state is “losing”, the command for designating the design and the command corresponding to the command are selected respectively. As a variation command, it is transmitted from the output port 260 to the composite sub-control board 300 side in the manner shown in FIGS. It made.

Next, the composite sub-control board 300 that has received the predetermined fluctuation command from the main control board 200 side in this way analyzes the fluctuation command and sends it to the effect symbol display board 320, the illumination control board 310, the speaker 42, and the like. On the other hand, the command is transmitted, and an effect mode transition lottery process as shown in FIG. 13 is performed.
That is, the composite sub-control board 300 (or its CPU) constantly monitors the command transmitted from the main control board 200 side, determines whether or not the variation command is received in the first step S100, and does not receive it. When (No), the reception waiting state is continuously maintained, but when it is determined that the reception has been received (Yes), the process proceeds to the next step S102, and the current effect mode on the effect symbol display board 320 (effect symbol display 30) is determined. Determine if you are in mission mode.

  As a result of this determination process, when it is determined that the current effect mode is the mission mode (Yes), the process jumps to the last step S108, but when it is determined that the current effect mode is not the mission mode (No) ) Shifts to the next step S104, performs a mission mode shift lottery process described later, and then shifts to the next determination step S106.

  In this determination step S106, as a result of the mission mode transition lottery process in the previous step S104, it is determined whether or not the transition to the mission mode is made. The same processing will be repeated, but when it is determined that the mode has been shifted to the mission mode (Yes), the process proceeds to the last step S108 and the transition process from the mission mode to the normal performance mode is performed. Returning to step S100, the same processing is repeated.

FIG. 14 is a flowchart showing an example of the flow from the normal effect mode to the mission mode shift lottery process in the effect mode shift lottery process.
First, if the transition to the transition lottery process shown in step S104 is started, the composite sub-control board 300 (the CPU) sets the change counter to “+1” in the first step S200 as shown in FIG. Is shifted to the determination step S202, whether or not the number of fluctuations of the fluctuation counter has reached “51”, that is, whether or not the number of fluctuations after the end of the mission mode has reached “51” as shown in the figure. Determine whether.

  As a result of this determination, when it is determined that the number of fluctuations after the end of the mission mode has not reached “51” (No), it is defined in the column of the number of fluctuations “0 to 50” in the transition ratio table 305 of FIG. As shown, since the lottery for shifting to the mission mode is not substantially performed, the process is terminated while the counter value is held, but it is determined that the number of fluctuations reaches “51 times”. If yes (Yes), the process proceeds to the next step S204, and whether or not the fluctuation count of the fluctuation counter has further reached “151”, that is, as shown in FIG. It is determined whether or not “151” times has been reached.

  As a result of this determination, when it is determined that the number of fluctuations has not reached “151” (No), that is, when the number of fluctuations is within the range of “51 to 150” times, step S208 is entered. After the transition and the mission mode transition lottery is performed at a ratio of “2/100” as defined in the column of the number of times of change “51 to 150” in the transition ratio table 305 of FIG. 11, the process proceeds to the next step S210. Transition.

  On the other hand, when it is determined that the number of fluctuations has reached “151” as a result of this determination (Yes), that is, when the number of fluctuations exceeds “151”, the process proceeds to step S206 and FIG. As specified in the column “151 to 250” of the number of changes in the transition ratio table 305, the mission mode transition lottery is performed at a ratio of “5/100”, and then the process proceeds to the next step S210.

  In step S210, it is determined whether or not the lottery for shifting to the mission mode has been won as a result of the transition lottery in each of these steps S206 and S208. If it is determined that the winner has been won (Yes), the process jumps to step S214. However, when it is determined that the winning combination has not been made (No), the process proceeds to the next step S212, where it is further determined whether or not the number of fluctuations has reached “251”.

As a result of this determination, when it is determined that the number of changes after the end of the mission has not reached “251” times (No), the processing is terminated while retaining the counter value. When it is determined that it has reached (Yes), it is considered that the number of fluctuations since the end of the last mission mode has reached the ceiling, and the process proceeds to the next step S214 to forcibly shift to the mission mode.
In step S214, the time (for example, “3 minutes” if there is an option of “1 to 5 minutes”) staying (moving) in the next mission mode is determined by a dedicated random number value or the like. .

  Then, when the transition time for the mission mode is determined in this way, the process proceeds to the next step S216, and a command (transmission to the mission mode) for transitioning from the normal rendering mode to the mission mode with respect to the rendering symbol control board 320. Command) is transmitted, the process proceeds to the last step S218, and the variation counter that has been accumulated so far is cleared (returned to "0"), thereby completing the lottery process for shifting from the normal performance mode to the mission mode. Will do.

FIG. 12 is a time chart showing the transition lottery process from the normal performance mode after the completion of the mission mode to the next “mission mode” in time series.
As shown in the figure, when the transition time of a certain mission mode is 3 minutes, the mission transition lottery ratio from the end of the 3-minute mission mode to the variation count “50” is “0/100”. In the meantime, there is no mode transition, but if the number of changes exceeds “50”, the mission transition lottery is performed at a ratio of “2/100” for each change, so the mode changes to the mission mode. Will arise.

Further, when the number of changes exceeds “150”, a mission transfer lottery is performed at a ratio of “5/100” for each change, so the probability of changing to the mission mode increases, and the change number is eventually set to “251”. In this case, it is assumed that the so-called ceiling has been reached and the mode is always shifted to the “mission mode”.
On the other hand, FIG. 15 is a flowchart showing an example of the flow of the lottery process for shifting from the mission mode to the normal effect mode in step S108 in the effect mode shift lottery process described above.

As shown in the drawing, in the transition process to the normal performance mode, first, the transition time measurement is started immediately after the transition to the mission mode in the first step S300, and the special prize performed during the mission mode is performed in the next step S302. It is determined whether or not “big hit” is won in the lottery.
As a result of the determination, when it is determined that “big hit” is won during the mission mode (Yes), the process jumps to step S306 to end the mission mode. Is determined not to be won (No), the process proceeds to the next determination step S304 and whether or not a predetermined time has elapsed after the transition to the mission mode, for example, the transition time determined in the previous step S214. If “3 minutes”, it is determined whether or not “3 minutes” have passed since the mode transition.

  As a result, when it is determined that the predetermined time has not elapsed since the transition to the mission mode (No), it waits as it is until the predetermined time elapses, but when it is determined that the predetermined time has elapsed (Yes) Shifting to the last step S306 and transmitting a command (transmission mode transition command) for transitioning from the normal rendering mode to the mission mode to the rendering symbol control board 320, thereby shifting the mission mode to the normal rendering mode. Will end.

  As described above, the gaming machine 100 of the present invention has a lottery probability of transition to the next special effect mode based on the number of fluctuations of the effect pattern after the transition from the special effect mode called “mission mode” or the like to the normal effect mode. As soon as the special performance mode is finished, the system immediately shifts to the next special performance mode immediately, or vice versa. It is possible to optimize the transition probability from the normal performance mode to the special performance mode by reducing the probability of occurrence of unevenness or variation in the transition rate such that the transition hardly occurs.

  In this embodiment, when the number of fluctuations after the end of the mission mode reaches “251” times, the transition to the next mission mode is always performed. However, such a so-called ceiling is not necessarily provided. Of course, the transition lottery ratio to the mission mode and the number of fluctuations thereof are not limited to the transition ratio table 305 in FIG.

  In addition, the “special effect mode transition lottery means” in the invention of claim 1 or the like described in the section for solving the problem corresponds to the “special effect mode transition lottery unit 304” according to the present embodiment. Similarly, the “effect symbol display means” in the invention of claim 1 and the like corresponds to the “effect symbol display board 320” and the “effect symbol display device 30” according to the present embodiment.
