Description

  The present invention relates to a ball game machine, and more particularly to a ball game machine that performs a big hit lottery due to entering a starting port and, if the lottery result is a win, displays a big hit symbol and shifts to a big hit game. .

  As a pachinko game machine that is a ball game machine, when a game ball enters the start opening, a big hit lottery is performed, and if the result is a big hit, a big hit game that opens the big winning opening is executed (No. 1) There is one kind of pachinko machine). Conventionally, in this type of pachinko gaming machine, a jackpot lottery is performed based on the jackpot determination random number extracted due to the ball entering the start opening, and the value of the jackpot determination random number is a specific value (jackpot determination) The special symbol is determined as the big hit symbol by the random number for determining the big hit symbol extracted at the time of entering the ball, and the content of the big hit game, for example, the big hit game is opened and closed based on the big hit symbol Determination of the opening time of the big prize opening and the number of rounds in which the big prize opening is opened and closed, the game state after the big hit game, for example, the probability change state that increases the big hit probability, or whether to shift to the short time state to increase the big hit lottery Have decided.

  The pachinko game machine displays the above jackpot symbol on the dot display or 7-segment LED, etc. under the control of the main control unit, while the sub-control unit (production symbol control unit, voice / lamp integrated control unit) supports the above jackpot symbol. The pseudo symbol to be displayed is displayed on a liquid crystal display device or the like, and the contents of the jackpot game and the game state after the jackpot game are shown in advance.

By the way, in recent pachinko gaming machines, various game states occur depending on the contents of the jackpot game, the game state after the jackpot game ends, and combinations thereof. In the future, the game state tends to increase more and more. Therefore, the number of jackpot symbols is required to be equal to or more than the number of gaming states generated due to the jackpot.
If the number of jackpot symbols is the same as the number of gaming states described above, the number of jackpot symbols is not so much, but the display of the jackpot symbol is small, so that the player plays the game while watching the pseudo symbols. In this case, the pseudo-symbol notifies the player of the contents of the jackpot game and the game state after the jackpot game using various effects, and the player plays the jackpot game with a sense of expectation. I am trying to enjoy it.
However, since the contents of the jackpot game and the game state after the jackpot game can be understood by looking at the display of the jackpot symbol display, this will waste a lot of pseudo symbols (direction), so that the bonus symbol will not be wasted. It is necessary to increase the number of jackpot symbols rather than the number of game contents and the number of gaming states after the jackpot game, making it difficult for the player to remember the symbol types.

  However, in the conventional pachinko gaming machine, since the gaming state is changed based on the jackpot symbol, the control of the jackpot symbol must be performed by the main control device that controls the entire gaming machine and is difficult to perform fraud. If the number of jackpot symbols increases, the amount of jackpot symbol data stored in the main controller increases, and the jackpot symbol determination random number extracted at the time of entering the starting port is compared with each symbol data. There has been a problem that the number of times of program processing for determining the big hit symbol increases, and the processing load of the main control device increases.

  As a conventional pachinko gaming machine, Patent Document 1 below discloses a gaming machine in which many combinations of jackpot symbols are set. This is intended to facilitate program diversion with other models, and does not reduce the processing load on the main controller.

The production symbol control device 82 controls the display of the LCD panel according to the command sent from the voice / lamp integrated control device 83.

Next, the operation of the pachinko machine 50 will be described.
First, an outline of a “main routine” executed by the main controller 80 (strictly, its CPU) will be described with reference to FIG. The “main routine” is composed of the main processing (S10 to S80) and the remaining processing (S85 to S95). The main routine is started due to an interrupt signal having a period of 2 ms (or 4 ms), and first determines whether or not it is a normal interrupt. (S10). This determination is made based on whether or not a specific numerical value is written at a specific address in the RAM. If the determination is negative (NO), the initial setting (S15) is executed. The numerical value for determining whether or not it is a normal interrupt is written in the RAM as part of this initial setting.

If it is a normal interruption (S10: YES), update processing of various random numbers (see FIG. 21) is executed (S20 to S60).
The initial value random number 1 update process (S20) adds +1 to the value of the initial value random number 1 every time this process is executed, and gives 3593 integers from “0” to “3592” as the initial value random number 1. Create repeatedly in ascending order. When the initial value random number 1 reaches “3592” which is the maximum value, it loops to “0” and continues the addition process. The initial value random number 1 is used as an update initial value counter in the big hit determination random number update process (S35).
In the initial value random number 2 update process (S25), as in the initial value random number 1 update process, 251 integers from “0” to “250” are repeatedly generated in ascending order as the initial value random number 2. The initial value random number 2 is used as an update initial value counter in the hit determination random number update process (S50).
In the initial value random number 3 update process (S30), as in the initial value random number 2 update process, 251 integers from “0” to “250” are repeatedly generated in ascending order as the initial value random number 3 to determine the big hit symbol This is used as a counter for the initial value of the random number 1 update process (S40).

  The jackpot determination random number update process (S35) constitutes a jackpot determination random number counter that forms a random number for determination of success / failure, and, similar to the initial value random number 1 update process, 3593 random numbers from “0” to “3592”. Create integers in ascending order repeatedly. In this update process, when the random number reaches “3592” which is the maximum value in the first round, the next count starts counting with the initial value random number 1 at this time as the update initial value, When the value returns to “0” after passing through the value “3592” and becomes “1” less than the updated initial value, the count is started with the new initial value random number 1 as the updated initial value. According to this, the random number for determining big hits can be made unpredictable, and even if the updated initial value is changed, the structure of making a round of 3593 integers that are the components of the random number does not change, so the appearance rate of random numbers is uniform. Can be.

The big hit symbol determination random number 1 update process (S40) constitutes a big hit symbol determination random number 1 counter that forms a random number for game mode determination, and a counter that repeatedly creates 250 integers from “0” to “249”. Constitute. In this update process, counting is started with the value of the initial value random number 3 as the update initial value, the random number value is made unpredictable, and the appearance rate of the random number is made uniform.
The big hit symbol determination random number 2 update process (S45) constitutes a big hit symbol determination random number 2 counter that forms a random number for big hit symbol determination, and creates a counter that repeatedly creates eight integers “0” to “7”. Constitute.

  The hit determination random number update process (S50) constitutes a hit determination random number counter used for the normal symbol lottery. As with the big hit determination random number update process (S35), "0" to " 251 integers up to 250 "are repeatedly generated in ascending order. In this update process, counting is started with the value of the initial value random number 2 as the update initial value, the random number value is made unpredictable, and the appearance rate of the random number is made uniform.

The reach determination random number update process (S55) constitutes a counter that repeatedly creates 229 integers from "0" to "228".
The variation pattern determination random number update processing (S60) constitutes a counter that repeatedly creates 1021 integers from “0” to “1020”.

  The jackpot determination random number, the jackpot symbol determination random number 1, the jackpot symbol determination random number 2, the reach determination random number and the variation pattern determination random number shown in FIG. 21 are supplied to the first start port 22A or the second start port 22B. Extracted due to game balls entering. Each random number extracted at the time of entering the first starting port 22A is stored as a reserved memory in FIG. 1, and each random number extracted at the time of entering the second starting port 22B is stored as a reserved memory in FIG. Remembered.

  The big hit determination random number relates to a special drawing lottery and is used for the big hit lottery and the small hit lottery. There are 3593 random numbers from “0” to “3592”, and if the random number value is “773 to 777” or “1773 to 1777”, it is a big hit in the normal probability state. If the random number value is “773 to 777”, “1773 to 1777”, “2743 to 2777”, or “3732 to 3777”, it is a big hit in a high probability state (during probability change). Furthermore, in the lottery of FIG. 1 due to the entrance to the first starting port, if the random number for the big hit determination random number is “301 to 315”, it will be a small hit in both the normal probability and the high probability state, 2. In the lottery of FIG. 2 due to the entrance to the starting port, the random value is “301” and a small hit is made.

The jackpot symbol determining random number 1 used as a random number for determining the game mode is 250 patterns of “0” to “249”, and one game mode is selected from the different types of game modes as shown in FIG. 19 and FIG. Used to determine
The types of game modes include the game contents of the jackpot game that was a big hit in the special drawing (the number of rounds of the big prize opening, the opening time of the big prize opening) and the gaming state (probability change state and They are distinguished by the number of times set in the short-time state).
The probability variation state is a state in which the probability of winning a big hit in a special drawing is high, and the short-time state is a long open time of a normal electric accessory (a long open time even in a certain variation state) This is a state in which the variation time of the normal symbol is short and the variation time of the special symbol is short.

For example, in the “Special Figure 1-16R Mode 4”, the continuous operation of opening the big winning opening of the big hit game is 16 rounds, and the big winning opening opening time of the first consecutive operation (the first round) is 0.2. The second is 5 times, and the opening time of the grand prize opening for the 2nd to 16th continuous operations (2nd to 16th rounds) is 28 seconds. Then, as a gaming state to be shifted to after the big hit game is finished, the probability variation function is activated until the special drawing lottery is performed 75 times, and the time-shortening function is activated until the special drawing lottery is performed 70 times. .
In “Special Figure 1-16R Mode 5”, the contents of the jackpot game and the setting of the operation of the probability changing function are the same as those in “Special Figure 1-16R Mode 4”, but the number of times of the time reduction function is set to 100 times. is there.
In “Special Figure 1-16R Mode 1”, the opening of the big prize opening is 16 rounds, and the opening time of the big prize opening is 1.8 seconds in all rounds. Then, the number of times of setting the probability changing function and the time saving function after the big hit game is finished is set in the same manner as in “Special Figure 1-16R Mode 4”.
In “Special Figure 1-16R Mode 2”, the number of rounds for opening the special prize opening, the number of times the probability changing function and the time reduction function are set are the same as in “Special Figure 1-16R Mode 1”, In the round, 1.8 seconds is set to 2 times.
Also, in “Special Figure 1-16R Mode 3”, the special prize opening time is set to 3 times for 1.8 seconds in all rounds, and the others are the same as “Special Figure 1-16R Mode 1”. .
In “Special Figure 1-5R Mode 1”, the winning opening is set to 5 rounds, and the opening time for the first winning opening in the first round is 0.2 seconds for 5 times and 27 seconds for 1 time. The opening time of the round is 28 seconds. The set number of times of the probability changing function and the time reduction function is set in the same manner as in “Special Figure 1-16R Mode 3”.
In “Special Figure 1-5R Mode 2”, the number of rounds of the big prize opening is the same five rounds as “Special Figure 1-5R Mode 1”, and the big prize opening time is 0.2 seconds in all rounds. The setting of the probability variation function is the same as “Special Figure 1-5R Mode 1”, but the setting of the time-shortening function is set to 100 when the time-shortening function is activated at the time of drawing the special figure.
In “Special Figure 1-5R Mode 2”, another game mode is set in which the time reduction function is not activated when the time reduction function is not activated at the time of drawing the special figure.

  Thus, in this pachinko machine, there are eight game modes: “16R mode 4, 16R mode 5, 16R mode 1, 16R mode 2, 16R mode 3, 5R mode 1, 5R mode 2, 5R mode 2 and other modes” It is as. The game mode setting is common to the lottery shown in FIG. 1 and the lottery shown in FIG. 2. However, the lottery shown in FIG. 1 and the lottery shown in FIG. Is different. For example, in the lottery of the special figure 1, if the big hit symbol determining random number 1 is “73”, the special figure 1-16R mode 4 is determined. In the lottery, “Special Figure 2-16R Mode 1” is determined.

  When the game mode is determined, the auxiliary number of the game mode is set. The auxiliary number is used when determining the jackpot symbol. A plurality of auxiliary numbers are set by the numerical value of the jackpot symbol determining random number 1 which is a reference for determining the game mode even in the same game mode. For example, in “Special Figure 1-16R Mode 4”, if jackpot symbol determination random number 1 is “0”, it is “auxiliary number 1”, and if jackpot symbol determination random number 1 is “66”, “auxiliary number 2” To "".

  As shown in FIG. 21, there are eight types of jackpot symbol determination random numbers 2 from “0” to “7”. As shown in FIG. 19 and FIG. 1 stop symbol, special figure 2 stop symbol) are determined. For example, if the random value of the jackpot symbol determining random number 2 is “2” and the combination of “auxiliary number 1”, “symbol 2” is selected. The big hit symbol determining random number 2 is also a criterion for selecting a small hit symbol. Note that the jackpot symbol determined by the combination of the auxiliary number and the random number 2 for determining the jackpot symbol is the same for the lottery of the special figure 1 and the lottery of the special figure 2, but in the special figure 1 and the special figure 2 the big hit Even if the symbols are the same, the game mode is not always the same. For example, if “symbol 9” is set in special figure 1, the game mode is “special figure 1-16R mode 4”, but if “symbol 9” is set in special figure 2, “special figure 2-16R” is set. The game mode is “Mode 1”. This is because the relationship between the value of the jackpot determination random number 1 and the game mode is different between the special figure 1 and the special figure 2. In addition, the probability that the game mode is selected is different between Special Figure 1 and Special Figure 2. For example, “Special Figure 1-16R Mode 4” is selected with a probability of 102/250, while “Special Figure 2-16R Mode 4” is selected with a probability of 73/250.

22 and 23 show the big hit symbol, the small hit symbol, and the lost symbol actually displayed on the special figure 1 or special figure 2 display devices 16A and 16B. The number of symbols determined based on the jackpot symbol determining random number 2 is 31 types including 28 types of jackpot symbols and three types of small hit symbols.
As described above, even if the same “symbol 9” is displayed, the game mode to be performed differs depending on the display devices 16A and 16B to be displayed. It is more difficult to know what happens.
Note that the jackpot symbol displayed on the special symbol 1 or special symbol 2 display devices 16A, 16B is difficult to identify because the display is small, and the player plays the game by looking at the pseudo symbol displayed on the effect symbol display device 15.

As shown in FIG. 21, when the period of the random numbers of the jackpot symbol determining random number 1 and the jackpot symbol determining random number 2 is compared, the jackpot symbol determining random number 1 is “0 to 249” and the size of the random number is 250. So the cycle of random numbers is
“2 (ms) ÷ 1000 × 250 = 0.5 (seconds)” (where 2 ms is the interrupt cycle). In this case, since the cycle of the random number is longer than 0.05 seconds, the selected random number value can be estimated. Therefore, it is necessary to update the initial value random number by processing the initial value random number 3.
On the other hand, the jackpot symbol determining random number 2 is “0 to 7” and the random number has eight sizes.
So the cycle of random numbers is
“2 (ms) ÷ 1000 × 8 = 0.016 (seconds)”. In this case, since the random number cycle is shorter than 0.05 seconds, it is not possible to guess the selected random number value, so that the initial value random number need not be updated.
Even in a pachinko machine in which the interrupt cycle is set to 4 ms, the random number cycle of the jackpot symbol determination random number 1 is longer than 0.05 seconds, so that the initial value random number needs to be updated. On the other hand, since the cycle of the random number 2 for the big hit symbol determination random number is shorter than 0.05 seconds, it is not necessary to update the initial value random number.

The reach determination random numbers are 229 from “0” to “228”. If the random number value is “0 to 20”, the reach is when the fluctuation time reduction function is not activated in the normal probability state, and “0 to 4”. If there is, the reach is when the function for reducing the variation time is activated in the normal probability state, and the reach is in the high probability state if “0 to 5”.
The random number for determining the variation pattern is 1021 from “0” to “1020” and determines the variation mode of the pseudo symbol.

  The random number for hit determination is extracted at the time of passing through the start gate 21 of the normal symbol, and is stored as a general symbol hold memory. The hit determination random number is used to determine whether or not a normal symbol lottery is successful. There are 997 random numbers from “0” to “996”. If the random number value is “31-40”, it is won in the normal probability state, and if it is “31-996”, it is won in the high probability state.

In the winning confirmation process (S65) of FIG. 5, it is confirmed whether or not there is a entrance to each entrance 22A, 22B, 24, 25 and whether there is a passage through the start gate 21. Subsequently, an output determination process (S75) and an fraud monitoring process (S80) such as a winning determination process (S70) for lottery lottery, an image output process, and the like are executed. The success / failure determination process (S70) will be described later.
In each output process (S75), according to the progress of the game, the main control device 80, the special figure 1, the special figure 2, the usual display device 16A, 16B, and these holding number display devices 17A, 17B, various solenoids, Output processing is executed for each of the payout control device 81, the launch control device 84, the voice / lamp integrated control device 83, the production symbol control device 82, and the like.
The fraud monitoring process (S80) is a process for monitoring whether or not the entrances 24 and 25 are fraudulent, and a predetermined rule for entering a game ball into the entrance within a predetermined time. It is a process for judging whether or not the number is larger than the number and notifying that the number is larger and notifying that fact.

  The main routine performs the initial value random number 1 update process (S85) and the initial value random number 2 update process (S90) within the remaining time until the next interrupt signal is input after performing this process (S10 to S80). The initial value random number 3 update process (S95) is looped. These processes are the same as S20, S25, and S30.

Hereinafter, a part of subroutine processing such as winning confirmation processing (S65), success / failure determination processing (S70), each output processing (S75), etc., which are processing executed by the main controller 80, which are closely related to the present invention, will be described.
The “start winning confirmation process” shown in FIG. 6 is a subroutine of a winning confirmation process (S65). First, it is confirmed whether there is a ball in the first starting port 22A (S100). If there is an incoming ball (S100: YES), it is confirmed whether the reserved memory is full for the reserved memory in FIG. 1 (S105). If it is not full (S105: NO), the jackpot determination random number, the jackpot symbol determination random number 1, the jackpot symbol determination random number 2, the reach determination random number, and the fluctuation pattern extracted at the time of entering the first start port 22A The random number for determination is stored as reserved storage in FIG. 1 (S110).
After NO determination in S100, YES determination in S105, or holding storage process (S110) of special figure 1 (S110), it is confirmed whether there is a ball in the second starting port 22B (S125) and whether the holding memory of special figure 2 is full If it is not full (S130: NO), the big hit determining random number, the big hit symbol determining random number 1, the big hit symbol determining random number 2, which are extracted at the time of entering the second starting port 22B, reach determination The random number for use and the random number for determining the variation pattern are stored as reserved storage in FIG. 2 (S135).

  7 to 10 show a flowchart of the “win / fail determination process”. As shown in FIG. 7, the “win / fail determination process” checks whether the special electric accessory is in operation (S200). If not, it checks whether the symbol is changing (S205). Then, it is confirmed whether a fixed symbol is displayed (S210). If the special electric accessory is operating (S200: YES), the process proceeds to “special game processing”.

If the confirmed symbol is not being displayed in the process of S210, as shown in FIG. 8, it is confirmed whether there is a reserved memory of the special figure 2 (S215). If there is the reserved memory of the special figure 2 (S215: YES), the number of the reserved memory of the special figure 2 is subtracted, and the shift process of the reserved memory is performed (S220).
If there is no special memory in FIG. 2 (S215: NO), it is checked whether there is special memory in FIG. 1 in S225. If there is special memory in FIG. 1 (S225: YES), special memory in FIG. The number is subtracted, and the hold storage shift process is performed (S230).
In this way, by confirming the reserved memory in FIG. 2 before the reserved memory in FIG. 1, the lottery in FIG. 2 is prioritized and executed over the lottery in FIG. Yes. If there is no reservation memory of special figure 2 or special figure 1 (S225: NO), it will transfer to "special game processing".

  Next, in the process of S235, the probability variation flag is confirmed to confirm whether or not the current gaming state is in the probability variation (high probability) (if the probability variation flag is 1, the probability variation is in progress). If the probability change is being performed in the process of S235 (S235: YES), it is set so as to determine whether or not it is correct using the high-probability determination table at the time of the probability change (S240). If the probability change is not in progress (S235: NO), it is set so as to determine whether or not the low-probability determination table is used (S245).

  In the process of S250, whether or not it is a big hit is determined by comparing the hit determination table set in the process of S240 or S245 with the big hit determination random number. If it is a big hit (S250: YES), a big hit symbol determination process is executed (S255).

As shown in FIG. 11, in the “big hit symbol determination process”, the big hit symbol determination random number 1 is confirmed (S500), and whether the big hit is the special symbol 1 (S505). If the big hit is special figure 1 (S505: YES), it is confirmed whether the big hit symbol determining random number 1 of special figure 1 is "0 to 101" (S510). “Mode 4” is set (determined) (S515).
At this time, an auxiliary number of the game mode is set according to the determined game mode and the jackpot symbol determining random number 1. For example, if the value of the jackpot symbol determining random number 1 is “65” in “Special Figure 1-16R Mode 4”, “Auxiliary Number 1” is set.
If S510 is NO, it is confirmed whether the jackpot symbol determining random number 1 is “102 to 121” (S520). If YES, “Special Figure 1-16R Mode 5” is set and an auxiliary number is set. (S525).
If S520 is NO, it is checked whether the jackpot symbol determining random number 1 is “122 to 145” (S530). If YES, “Special Figure 1-16R Mode 1” is set and an auxiliary number is set. (S535).
If S530 is NO, check whether the jackpot symbol determination random number 1 is “146 to 151” (S540). If YES, set “Special Figure 1-16R Mode 2” and set the auxiliary number. (S545).
If S540 is NO, check whether the jackpot symbol determination random number 1 is “152 to 157” (S550). If YES, set “Special Figure 1-16R Mode 3” and set the auxiliary number. (S555).
If S550 is NO, it is confirmed whether the jackpot symbol determining random number 1 is “158 to 177” (S560). If YES, “Special Figure 1-5R Mode 1” is set and an auxiliary number is set. (S565).
If S560 is NO, check whether the jackpot symbol determining random number 1 is “178 to 249” (S570). If YES, set “Special Figure 1-5R Mode 2” and set the auxiliary number. (S575).

  After the game mode of the special figure 1 is set in the processing of S515 to S575, the big hit symbol determination random number 2 is confirmed (S580), and in the processing of S585, the auxiliary number of the determined game mode and the big hit symbol determination random number are determined. The jackpot symbol of the special figure 1 is selected by combination with 2 (S585). For example, if “subsidiary number 1” and the jackpot symbol determining random number 2 are “3”, “symbol 2” is determined.

If S505 is NO and the jackpot is special figure 2, as shown in FIG. 12, it is confirmed whether the jackpot symbol determining random number 1 is “0 to 72” (S590). "2-16R mode 4" is set and an auxiliary number is set (S595).
If S590 is NO, it is checked whether the jackpot symbol determining random number 1 is “102 to 121” (S600). If YES, “Special Figure 2-16R Mode 5” is set and an auxiliary number is set. (S605).
If S600 is NO, it is confirmed whether the jackpot symbol determining random number 1 is “73 to 89” or “122 to 145” (S610). If YES, “Special Figure 2-16R Mode 1” is selected. The auxiliary number is set (S615).
If S610 is NO, it is confirmed whether the jackpot symbol determining random number 1 is “90 to 95” or “146 to 151” (S620). If YES, “Special Figure 2-16R Mode 2” is selected. The auxiliary number is set and set (S525).
If S620 is NO, check whether the jackpot symbol determining random number 1 is “96 to 101” or “152 to 157” (S630). If YES, “Special Figure 2-16R Mode 3” is selected. The auxiliary number is set and set (S635).
If S630 is NO, check whether the jackpot symbol determination random number 1 is “158 to 226” (S640). If YES, set “Special Figure 2-5R Mode 1” and set the auxiliary number. (S645).
If S640 is NO, check whether the jackpot symbol determination random number 1 is “227 to 249” (S650). If YES, set “Special Figure 2-5R Mode 2” and set the auxiliary number. (S655).

  After the game mode of the special figure 2 is set in the processing of S595 to S655, the big hit symbol determination random number 2 is confirmed (S660), and in the processing of S665, the auxiliary number of the determined game mode and the big hit symbol determination random number are determined. 2 is selected in combination with 2 (S665).

  Subsequently, in the process of S260 shown in FIG. 8, a variation pattern determination process is performed based on the variation pattern determination random number, and the game mode determined in the jackpot symbol determination process (S255) is set (stored) as a jackpot information. (S265). Then, a special figure variation start command is transmitted to the special figure 1 or special figure 2 display devices 16A and 16B, the production symbol control device 82 and the voice / lamp integrated control device 83 (S309).

If it is not a big hit in the process of S250 (S250: NO), it is determined whether it is a small hit (S270). If it is a small hit (S270: YES), a small hit symbol determination process (S275) determines the small hit symbol.
As shown in FIG. 13, in the “small hit symbol determining process”, the big hit symbol determining random number 2 is confirmed (S670), and the symbol is selected in the small hit symbol setting process of S675 (see FIG. 19 or FIG. 20).

When the small hit symbol is determined, the process returns to S280 in FIG. 8 to determine the variation pattern.
On the other hand, if it is not a small hit in the process of S270 (S270: NO), the variation pattern is determined (S285). After determining the fluctuation pattern (S280, S285), it is confirmed whether the probability change is in progress (S290). If the probability change is in progress (S290: YES), the probability change counter is subtracted (S295), and whether or not the release extension flag is 1 ( (S300). If S290 is NO, the process jumps to S300.
If the opening extension operation is being performed (S300: YES), the opening extension counter is subtracted (S305), and the process proceeds to S309. If the opening extension operation is not being performed (S300: NO), the process jumps to S305 and proceeds to the process of S309.

  When the symbol is changing in the process of S205 in FIG. 7 (S205: YES), as shown in FIG. 9, when it is confirmed that the symbol change time has passed (S310: YES), the fixed symbol display setting process (S315) ), A command is transmitted to the special figure 1 or special figure 2 display devices 16A and 16B, the production symbol control device 82, and the voice / lamp integrated control device 83 so as to be confirmed and displayed.

Subsequently, it is confirmed whether or not the special figure that is confirmed and displayed is a combination that makes a big hit (S320). If it is a combination that makes a big hit (S320: YES), if the probability variation flag is 1, (S325: YES) ), The probability variation flag is set to 0 (S330), and if the release extension flag is 1 (S335: YES), the release extension flag is set to 0 (S340).
Subsequently, the operation of the condition operation device is started (S345), the operation of the accessory continuous operation device is started (S350), and the effect symbol control device 82 and the voice / lamp integrated control device 83 are performed by the big hit start effect processing (S355). A command is sent to start the big hit effect, and the process proceeds to “special game processing”.

If the combination in step S320 is not a big hit (S320: NO), it is confirmed whether the probability variation flag is 1 (S360), the probability variation flag is 1 (S360: YES), and the probability variation number is 0 (S365). : YES), the probability variation flag is set to 0 (S370).
Subsequently, if the release extension flag is 1 (S375: YES) and the release extension count is 0 (S380: YES), the release extension flag is set to 0 (S385).
In the process of S390, it is checked whether the special figure is a combination that makes a small hit. If it is a combination that makes a small hit (S390: YES), the operation of the special electric accessory is started (S395), and the small hit start effect process is performed. In (S400), a command is transmitted to the effect symbol control device 82 and the voice / lamp integrated control device 83 so as to start the small hit effect, and the process proceeds to “special game processing”.
If the determination in S310 or S390 is NO, the process proceeds to “special game process”.

  When the confirmed symbol is being displayed in the process of S210 in FIG. 7 (S210: YES), as shown in FIG. 10, when it is confirmed that the display time of the confirmed symbol has passed (S310: YES), the confirmed symbol display setting process In step S315, a command is sent to the special figure 1 or special figure 2 display devices 16A and 16B, the production symbol control device 82, and the voice / lamp integrated control device 83 so as to end the display of the confirmed symbol, and the "special game processing" Migrate to

As shown in FIG. 14, in the “special game process”, first, it is confirmed whether or not the accessory continuous operation device is in operation (S700). If it is in operation (S700: YES), the prize winning opening is determined in the process of S705. Check if it is open. If the accessory continuous operation device is not in operation (S700: NO), the process proceeds to “small hit game processing” described later.
If the big winning opening is not open in the process of S705 (S705: NO), it is confirmed whether it is during the interval (S710), if not during the interval (S710: NO), it is confirmed whether the big hit end effect is being performed (S715), If it is not during the jackpot end effect (S715: NO), it is confirmed whether the jackpot start effect time has passed (S720), and if the jackpot start effect time has passed (S720: YES), the big prize opening is opened at S725. Execute the setting process and return.

  If the big winning opening is being opened in the process of S705 (YES), as shown in FIG. 15, whether or not there are ten (specified number) winnings in the big winning opening (S730), or It is confirmed whether or not the opening time has expired (S735). If any of them can be confirmed, the big prize opening is closed (S740), the big hit interval process is executed (S745), and the process returns.

  If it is during the interval in the processing of S710 of FIG. 14 (YES), as shown in FIG. 16, it is confirmed whether or not the big hit interval time has passed (S750), if it has passed (S750: YES), the final It is confirmed whether it is a round (S755), and if it is the final round (S755: YES), a big hit end effect process (S760) is executed and the process returns. On the other hand, if it is not the final round (S755: NO), the winning opening opening setting process (S765) is executed and the process returns.

  If the big hit end effect is in the process of S715 in FIG. 14 (YES), as shown in FIG. 17, it is confirmed whether or not the big hit end effect time has passed (S770), and if it has passed (S770: YES). ), A process for stopping the operation of the accessory continuous operation device (S775) is executed, and a process for stopping the operation of the condition device (S780) is executed.

  In the subsequent jackpot information setting reference process of S785, the “game mode” of the jackpot information stored in the process of S265 of the “win / fail judgment process” shown in FIG. 8 is referred to, and in the next probability variation number setting process (S787), the probability variation is changed. A period for which the state is continued, that is, a set number of times that the probability variation state is continued until the big hit lottery is repeated is determined. Then, the probability variation flag is set to 1 (S790). In this pachinko machine, the probability variation is made to function after every big hit game, and the set number of times is 75 (see FIGS. 19 and 20).

Next, based on the “game mode” referred to above, it is confirmed whether or not the time saving function is provided (S795). Here, among the eight game modes described above, both Special Figure 1 and Special Figure 2 are “other modes of 5R mode 2”. Whether or not the above-mentioned “other mode of 5R mode 2” is checked.
If the game mode is other than the above-mentioned “other modes of 5R mode 2” and the setting is made to give the time-saving function (S795: YES), the time-saving state is continued in the next time-saving setting processing (S800). That is, the number of times of setting the time-short state to be continued until the big hit lottery is repeated is determined. Then, the time reduction flag is set to 1 (S805). In this pachinko machine, the number of time reduction settings is set to 100 times in both “16R mode 5” and “5R mode 2” in both FIG. 1 and FIG. 2, and is set to 70 times in other game modes.
If the determination in step S805 or NO in step S795 is NO, a jackpot end command is transmitted to the effect symbol control device 82 and the voice / lamp integrated control device 83 to end the jackpot game (S810), and the process returns.

  When the process shifts from S700 of “special game process” in FIG. 14 to “small hit game process”, as shown in FIG. 18, in “small hit game process”, the special electric accessory is in operation (S900: YES), If the small hit start effect is being performed (S905: YES) and the small hit start effect time has elapsed (S910: YES), the big prize opening process (S915) is executed and the process returns.

If the small hit start effect is not being performed in S905 (S905: NO), it is confirmed whether the small hit operation is in progress (S920). If a small hitting operation is being performed in the process of S905 (YES), it is confirmed whether or not there are 10 (predetermined number) winnings in the big winning opening (S925), and whether or not the opening time of the big winning opening has ended. Confirmation (S930) is performed, and if the machine constant winning and opening times can be confirmed, the large winning opening is closed (S935), the small hit end effect processing (S940) is executed, and the process returns.
If the small hit operation is not being performed in S920 (S920: NO), it is checked whether the small hit end effect time has passed (S945). If the time has passed (S945: YES), the operation of the special electric accessory is performed. It stops (S950), transmits a small hit end command to the effect symbol control device 82 and the voice / lamp integrated control device 83, ends the small hit game (S955), and returns.

According to the pachinko machine of this embodiment, when a game ball enters the first starting port 22A or the second starting port 22B, a big hit determining random number, a big hit symbol determining random number 1, a big hit symbol determining random number 2, etc. are extracted. Is done. If the lottery result of the big hit lottery based on the big hit determination random number is a big hit, the game mode including the contents of the big hit game and the game state after the big hit game is ended based on the big hit symbol determination random number 1 from eight modes. Select one. In effect, seven game modes are determined from 1 to 7.
In this case, the process for determining the game mode is to check whether or not the extracted random number 1 and the determination value indicating the game mode match to match each other. There are seven types corresponding to the game mode, and it is sufficient to execute the confirmation process seven times at most, and a small number of program processes are sufficient.
Then, one symbol is selected from 31 types of jackpot symbols by a combination of the auxiliary number set based on the determined game mode and the jackpot symbol determining random number 2. In this case, the jackpot symbol determining random number 2 has eight values “0 to 7”, and the processing required for determining the jackpot symbol is eight confirmation processes of the jackpot symbol determining random number 2 and seven games. Combined with the mode confirmation process, the process may be at most 15 times. As in the conventional case, in the configuration in which the big hit symbol is determined first and the game mode is determined, the program is at least 31 times depending on the type of the big hit symbol. Whereas processing is necessary, according to the configuration of the present embodiment, program processing can be reduced, and the burden on the main controller 80 can be reduced.

  In addition, since the big hit symbol is determined by the combination of the game mode with few types and the small number 2 for determining the big hit symbol with a small configuration, the data used as the determination criterion to be stored in the main controller 80 can be reduced, and the big hit Even if the symbols are increased, the main controller 80 is not burdened. The program is easy to manage and can be used with other pachinko machines with different types and numbers of jackpot symbols.

This pachinko machine is configured to perform a big hit lottery separately for Special Figure 1 and Special Figure 2. In Special Figure 1 and Special Figure 2, the types of big hit symbols and game modes are the same, but the same Even if it is a big hit symbol, there is a setting that the game mode is different. By setting in this way, it is difficult for the player to know what kind of game mode it will be if only the special symbol (big hit symbol) is seen. Can be made.
Further, although the probability of winning a big hit is the same between the special figure 1 and the special figure 2, the selection rate of the game mode that changes due to the big hit is different between the special figure 1 and the special figure 2. For example, in Fig. 1 the probability of becoming "Special Fig. 1-16R Mode 1" when a big hit is 24/250, but in Fig. 2 the probability of becoming "Special Fig. 2-16R Mode 1" when making a big hit Is 41/250.
