[About lottery processing]
FIG. 8 is a diagram showing an outline of the special figure success / failure determination table TB referred to in the special figure success / failure lottery. When the game ball enters the start winning component 60 or the variable start winning component 62, one special figure determination random number is acquired from the range of 0 to 65535. As shown in the figure, the special figure success / failure determination table TB includes a low probability special figure success / failure determination table TB1 which is referred to when the gaming state has a special figure low probability, and a gaming state having a special figure high probability. It is subdivided into a high-probability special figure success / failure determination table TB2. In the special figure success / failure determination tables TB1 and TB2, determination results ("winning" or "losing") corresponding to special figure success / failure determination random numbers from 0 to 65535 are defined. For example, when the low-probability special figure success / failure determination table TB1 is referred to, the probability that the determination result is “hit” is about 1/399, and the high-probability special-figure determination / rejection determination table TB2 is referred to. The probability that the determination result is a hit is about 1/3 of 10 times. When the acquired special figure success / failure determination random number is a random number corresponding to “winning”, the determination result is winning, and when the acquired random number corresponding to “losing” is determined, the determination result is determined to be lost.
In the special figure success / failure determination tables TB1 and TB2, there are two determination results, “win” and “lost”, but in addition, a table with “small hit” may be added.

  Although the details will be described later, the special figure low probability state is a gaming state in which the lottery result is determined with reference to the low probability special figure success / failure determination table TB1 in the special figure success / failure lottery. On the other hand, the special figure high probability state is a gaming state in which the lottery result is determined with reference to the high probability special figure success / failure determination table TB2 in the special figure success / failure lottery. It is a state where it is easy to win the above-mentioned special game.

  FIG. 9 is a diagram showing an outline of the special figure type determination table TB referred to in the special figure type determination lottery. As shown in the figure, the special figure type determination table TB is referred to when the special figure type determination random number is acquired when the start winning component 60 is entered and the result of the special figure determination lottery is a win. The special figure type determination table TB1 and the special figure type determination random number are acquired when the variable start winning component 62 is entered as a trigger, and the special figure referred to when the result of the above-mentioned special figure win / fail lottery is a win. It is subdivided into a type determination table TB2 and a special figure type determination table TB3 that is referred to when the result of the special figure win / loss lottery is lost.

When the start winning component 60 or the variable start winning component 62 is entered, one special figure type determination random number is acquired from a range of 0 to 99, for example. As shown in the figure, in the special figure type determination tables TB1 and TB2, special symbol types corresponding to special figure type determination random numbers from 0 to 99 are defined at a predetermined ratio (selection rate). For example, when the special figure type determination table TB1 is referred and the acquired special figure type determination random number is in the range of 0 to 69, the special figure type is determined as the special symbol A and is in the range of 70 to 99. In this case, the special figure type is determined as the special symbol B.
That is, the selection rate of the special symbol A and the special symbol B when the result of the special symbol winning / lottery lottery triggered by entering the start winning component 60 is “win” and the special symbol type determination table TB1 is referred to is as follows: 70% and 30% respectively.

  In addition, when the special figure type determination table TB2 is referred and the acquired special figure type determination random number is in the range of 0 to 79, the special figure type is determined as the special symbol C and is in the range of 80 to 99. In this case, the special figure type is determined as the special symbol D. In other words, the special symbol win / lottery lottery result triggered by entering the variable start winning component 62 is a win, and the selection rate of the special symbol C and the special symbol D when the special symbol type determination table TB2 is referred to is as follows. 80% and 20%.

  The special figure type determination table TB3 is referred to when the result of the special figure success / failure lottery is “losing”, and relates to the range of the acquired special figure type determination random number and the acquisition timing of the special figure type determination random number. The special symbol type is unconditionally determined as the special symbol X (losing symbol X).

  FIG. 10A is a diagram showing an example of the variation pattern determination table TB referred to in the special figure variation pattern determination lottery. In the present embodiment, the variation pattern table is subdivided into a variation pattern determination table TB1 that is referred to when the gaming state has a normal probability, and a variation pattern determination table TB2 that is referred to when the gaming state has a high probability. It becomes. When entering the start winning component 60 or the variable start winning component 62, for example, one variation pattern determination random number is acquired from a range of 0 to 99, and 1 corresponding to the variation pattern determination random number is obtained from any one of the variation pattern determination tables TB. The fluctuation pattern number is determined.

  As shown in the figure, in the variation pattern determination tables TB1 and TB2, the variation pattern determination random numbers are stored in accordance with the result of the special figure success / failure lottery determined by the lottery (the special figure determination result) and the number of reserved memories. Corresponding variation pattern numbers are defined. In the present embodiment, when the variation pattern special figure determination result is “winning”, the variation pattern number is determined according to the variation pattern determination random number regardless of the number of reserved storage. Note that the variation pattern determination tables TB1 and TB2 are merely examples, and for example, a variation pattern number that is different depending on the type of special figure in addition to the result of the special figure success / failure lottery and the number of reserved memories may be determined.

  As shown in FIG. 10 (b), each variation pattern number defined in the variation pattern determination tables TB1 and TB2 is associated with a variation time (second), and the variation time is the first special symbol display device. The variation display time of the special symbol displayed on the 35A or the second special symbol display device 35B, the variation time of the effect symbol S displayed variably in synchronization with the variation display of the special symbol on the effect display unit 50A, and It becomes the time of the variation effect displayed with the variation of the effect symbol S. The shortest variation time in this embodiment is, for example, 1.5 seconds, and the longest variation time is 90 seconds.

  When a variation pattern number is determined from any variation pattern determination table TB, a variation pattern command including the variation pattern number and information about variation time (variation information) is transmitted to the effect control circuit 200 side, and the effect symbol S In addition to the fluctuation display, a fluctuation effect that expresses various effects according to each variation pattern number is displayed on the effect display unit 50A.

  Further, the main control circuit 100 controls the first special symbol display device 35A or the second special symbol display device 35B simultaneously with the transmission of the variation pattern command, and starts the variation display of the special symbol on any of the display devices. Thereafter, the main control circuit 100 controls the first special symbol display device 35A or the second special symbol display device 35B based on the fact that the variation display time has elapsed, and stops the variation of the special symbol, and also performs the effect control. A special figure stop designation command, which will be described later, is transmitted to the circuit 200 side, and the fluctuation of the effect symbol S that is variably displayed on the effect display section 50A is stopped. As described above, the main control circuit 100 executes the above-described special symbol determination lottery, special symbol type determination lottery, and special symbol variation pattern determination lottery at the start of the variation of the special symbol, and finally the special symbol and the effect symbol S are finalized. The result of the special figure winning / losing lottery related to whether or not the special game can be executed is notified according to the mode of the stop.

The special game control table TB stores various data for controlling the special game. During the special game, the solenoid SOL2 that opens and closes the opening / closing body 64B is driven and controlled with reference to the table. A plurality of special game control tables TB are provided for each special figure type, and the corresponding table is set at the start of the special game according to the determined special figure type. The control data corresponding to all the special figure types is shown.

  The special game is composed of a plurality of round games in which the special winning opening 64A is opened and closed a predetermined number of times. The special game control table TB includes an opening time (a waiting time until the first round game is started), a maximum number of special electric actors activated (the number of round games executed during one special game), special Number of times of opening / closing switching of the electric accessory (number of times of opening of the big prize opening 64A in one round (R)), solenoid energization time (energization time of the solenoid SOL2 for each number of times of opening of the big prize opening 64A, that is, one big prize opening 64A opening time), the prescribed number (the maximum number of winnings possible to the big winning opening 64A in one round game), the big winning opening closing effective time (the closing time of the big winning opening 64A between round games, that is, the interval time) ), Ending time (waiting time from the end of the last round game until normal special game (special symbol variation display) resumes) As data are beforehand stored as shown in each Laid view type.

  For example, when a special game is executed when the special symbol type is special symbol A, the special winning opening 64A is opened for 29 seconds by the opening operation of the opening / closing body 64B by energizing the solenoid SOL2 as a special game mode. Alternatively, the round continues until any of the conditions that nine game balls (count C = 9) enter the big prize opening 64A is satisfied, and the round is repeated four times. Further, when the special game is executed when the special symbol type is the special symbol B, the special winning opening 64A is opened for 29 seconds by the opening operation of the opening and closing body 64B as a special game mode, or the special winning port 64A. The round continues until any of the conditions that nine game balls enter (count C = 9) is established, and the round is repeated ten times. When a special game is executed when the special symbol type is the special symbol C, the special winning game port 64A is opened for 29 seconds by the opening operation of the opening / closing body 64B, or the special winning ticket is opened as the special game mode. The round continues until any condition that nine game balls (count C = 9) enter in 64A is satisfied, and the round is repeated 15 times. When a special game is executed when the special symbol type is the special symbol D, the special winning game port 64A is opened for 29 seconds by the opening operation of the opening / closing body 64B, or the special winning ticket is opened as the special game mode. The round continues until one of the conditions that nine game balls enter the count 64A (count C = 9) is satisfied, and the round is repeated twice.

[About gaming state]
FIG. 12 is a diagram showing an outline of a game state setting table TB referred to for setting the game state after the special game when the above-described special game is executed. As shown in the figure, in the game state setting table TB, the game state after the special game corresponding to the special figure type and the number of games that the game state continues (the special figure high-precision number, the normal figure high-precision number ) Is prescribed. As shown in the gaming state setting table TB, in the present embodiment, the gaming state after a special game is a gaming state with a special figure high probability and a normal figure high probability regardless of the special figure type. In addition, when the special figure type is the special symbol A or the special symbol B, the number of games in which the special figure high probability and the normal figure high probability continue is set to 100, and the special figure type is the special symbol C or the special symbol D. In this case, the number of games where the special figure high probability and the normal figure high probability continue is set to 150 times. The special figure high-precision number and the usual figure high-precision number are set as count values of a special figure high-precision number cut counter and a common figure high-precision number cut counter, respectively, which will be described later, and are subtracted each time a special figure game is executed. . When the count value becomes 0, the gaming state is switched to a state with a low special probability and a normal low probability. The combination of the number of special figure types and the gaming state can be changed as appropriate according to the specifications of the pachinko machine 1, and by further subdividing and setting the special figure type, It is also possible to further subdivide and set the gaming state.

Here, the special figure low probability is a state in which the low probability special figure success / failure determination table TB1 shown in FIG. 8 is referred to in the above-mentioned special figure success / failure lottery (winning probability = 1/399). Further, the special figure high probability is a state in which the high-probability special figure success / failure determination table TB2 shown in FIG. 8 is referred to (hit probability = 1 / 39.9).
The ordinary figure low probability refers to the variation pattern determination table TB1 shown in FIG. 10A in the above-mentioned special figure variation pattern determination lottery. This is a state in which the normal-probability determination table TB1 is referred to and the low-probability general-purpose fluctuation pattern determination table TB1 shown in FIG. 14 is referred to when the determination result is “winning”.
The ordinary figure high probability is defined so that the variation time (seconds) determined in comparison with the variation pattern determination table TB1 shown in FIG. The variation pattern determination table TB2 is referred to, and in the below-mentioned lottery for normal / unusual lottery, the high-probability normal / failure determination table TB2 shown in FIG. 13 is referred to, and the high shown in FIG. This is a state in which the normal-use probability variation pattern determination table TB2 is referenced.

  As described above, in the pachinko machine 1, various lotteries are executed with the start winning component 60 or the variable start winning component 62 as a trigger, and the results of the various lotteries are predetermined results. A special game advantageous to the player is executed, and the game state after the special game is switched. On the other hand, in the pachinko machine 1, a lottery regarding whether or not a normal game can be performed by opening and closing the opening / closing body 620 provided in the variable start winning component 62 is independent of the various lotteries regarding the execution of the special game. Drawing lottery lottery, common figure variable time pattern determination lottery) are also executed. In the following, an outline of various lottery processes (ordinary games) relating to whether or not a normal game can be executed will be described.

  When the game ball passes through the passing gate 68 while flowing down the right-handed area 31B, a normal-game win / fail determination random number referred to in a normal-game win / fail lottery described later is acquired, and the acquired random number is stored in the reserved storage area of the RAM 100c. Is done. Here, the reserved storage area has a general-purpose storage area that can store the above-mentioned normal / unusual determination random number, and the general-purpose storage area has four storage units (first to fourth storage units). ing. Then, when the game ball passes through the passing gate 68, the random number for determining whether or not it is normal is stored in order from the first storage unit. However, the number of reserved drawings (X3) that can be stored in the reserved map storage area is set to four, and the number of reserved drawings X3 does not increase beyond the upper limit.

  FIG. 13 is a diagram showing an outline of a general-purpose success / failure determination table TB that is referred to in the general-purpose determination success / failure lottery. When the game ball passes through the passage gate 68, for example, one normal / unusual determination random number is acquired from a range of 0 to 99. As shown in the figure, the normal / unusual determination table TB is a low-probability normal / non-probability determination table TB1 that is referred to when the gaming state has the above-mentioned ordinary-low probability, and the gaming state has a high-probability probability. It is subdivided into a high-probability common-use determination table TB2 referred to in this case. In the above-mentioned normal / failure determination tables TB1 and TB2, determination results (“winning” or “losing”) corresponding to the normal / unusual determination random numbers from 0 to 99 are defined. For example, the probability that the determination result is “winning” when the low-probability common-use determination table TB1 is referenced is 1/50. On the other hand, the probability that the determination result is a win when the high-probability common-use determination table TB2 is referenced is 1/2. When the acquired normal / unusual determination random number is a random number corresponding to “win”, the determination result is a win, and when it is a random number corresponding to “lost”, the determination result is a loss.

  FIG. 14 is a diagram for explaining a general-purpose variation pattern determination table TB referred to in a general-purpose variation pattern determination lottery. When the above-mentioned common figure win / fail lottery is performed, the fluctuation time of the normal symbol is determined based on the common figure fluctuation pattern determination table TB. As shown in the figure, the normal variation pattern determination table TB is a low probability general variation pattern determination table TB1 that is referred to when the gaming state has a normal low probability. It is subdivided into a high probability common figure variation pattern determination table TB2 referred to in a certain case, and a single variation time is defined in each table. Then, according to the low probability regular pattern variation pattern determination table TB1, the variation time of the normal symbol is determined to be “30 seconds”, and according to the high probability regular pattern variation pattern determination table TB2, the variation time of the normal symbol is determined. It is determined to be “1 second”. When the variation time of the normal symbol is determined in this manner, the variation display of the normal symbol displayed on the normal symbol display device 37 is started over the determined variation time. The display is stopped and displayed in a manner indicating the result of drawing lottery.

  Here, the normal symbol display device 37 is configured, for example, as a form in which a plurality of LED lamps are arranged, and the plurality of lamps blink during the variable display, and the result of the lottery drawing lottery wins. Is in a state where any one of the plurality of lamps is turned on and stopped, and when it is lost, for example, all the LED lamps or some of the lamps are turned off. In the above description, an example in which a single variation time is defined according to the gaming state is shown, but a plurality of variation times are defined in each gaming state, and each ordinary gaming state varies depending on a lottery with a predetermined random number. It is good also as a structure by which the variation time of a symbol is determined.

FIG. 15 is a diagram showing an outline of the opening / closing body operation table TB referred to in a normal game executed when the result of the above-mentioned lottery for lottery win is a win and the game is stopped in a mode indicating that a normal symbol is a win. It is. As shown in the figure, the opening / closing body operation table TB defines the number of times the opening / closing body 620 is opened and the opening time per opening operation, and is referred to when the gaming state is usually low probability. Are divided into a low-probability opening / closing body operation table TB1 and a high-probability opening / closing body operation table TB2 which is referred to when the gaming state is normally high probability.
In the case where the gaming state is normally low, when the normal symbol stops in a manner that indicates a win, the solenoid SOL1 is energized by referring to the opening / closing body operation table TB1, and the variable start winning component 62 is controlled. The opening / closing body 620 is opened once for 0.3 seconds.
On the other hand, when the gaming state is normally high probability, when the normal symbol is stopped in a manner in which the symbol is a win, the solenoid SOL1 is energized and controlled by referring to the opening / closing body operation table TB2, and the variable start winning component The operation in which the 62 open / close bodies 620 are opened for 1.8 seconds is repeated three times.
In other words, when the gaming state is a high probability of a normal figure, the probability that a lottery result will be “hit” is higher than when a low probability of a normal figure, and the fluctuation time of a normal symbol is greatly reduced. In addition, since the total opening time of the opening / closing body 620 becomes longer, it becomes easier for the game ball to enter the variable start winning component 62, and the opportunity to enter the variable start winning component 62 while suppressing consumption of the game ball is triggered. It becomes possible to efficiently perform the above-mentioned special figure game. Therefore, when the game state is normally high probability, the player frequently adjusts the operation amount of the handle unit 7 so that the game ball flows down in the right-handed region 31B, so that the game ball frequently passes the passing gate 68. It will be easier to receive the above benefits. In the present embodiment, the three factors of the probability that the lottery result is “winning”, the variation time of the normal symbol, and the opening time of the opening / closing body 63 are more advantageous than the case of the low probability of usual drawing. However, the present invention is not limited to this, but it is not limited to this, and a state with a high probability of ordinary figure is created by changing at least one of the above three elements. It is also possible to do.
