DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball-and-ball game machine such as a pachinko game machine and a coin game machine, and more particularly to a variable display device whose display state can be changed, wherein a display result on the variable display device is predetermined. The present invention relates to a ball game machine that can provide a predetermined game value when a specific display mode is set.

[0002]

2. Description of the Related Art As a gaming machine, a variable display device having a variable display portion whose display state can be changed is provided, and when a display result of the variable display portion becomes a predetermined specific display mode, a predetermined game is performed. Some are configured to provide value to the player. The variable display device includes a plurality of variable display units, and is generally configured to display the display results of the plurality of variable display units at different times. On the variable display section, for example, a plurality of identification information such as symbols are variably displayed. The fact that the display result of the variable display unit is a combination of predetermined specific display modes is usually referred to as “big hit”. In addition, the game value is a right to make the state of the variable prize ball device provided in the game area of the gaming machine advantageous for a player who is easy to win a hit ball, or a right for the player to be in an advantageous state. Or to generate.

[0003] In addition, among the combinations of the display modes of "outside" other than the combination of "big hit", at a stage where some of the display results of the plurality of variable display portions have not been derived and displayed yet, the display results are already displayed. The state in which the display mode of the variable display unit that is derived and displayed satisfies the display condition that is a combination of the specific display modes is referred to as “reach”. A player plays a game while enjoying how to generate a big hit.

[0004] In such a gaming machine, when a big hit occurs, for example, the variable winning ball device is opened a predetermined number of times, and the hit ball is in a state of being easily won. Then, in each open period, when a predetermined number (for example, 10) of variable prize ball devices are won, the variable prize ball devices are closed. The number of times the variable winning ball device is opened is a predetermined number (for example, 16 rounds).
It is fixed to. Further, the number of award balls to be paid out in accordance with the winning of a hit ball to the variable winning ball apparatus is a predetermined number (for example, 16
). Note that the opening time (for example, 29 seconds) is determined for each opening, and the variable winning ball device closes when the opening time elapses even if the number of winnings does not reach the predetermined number, but generally, the winning number reaches the predetermined number. It is rare for the opening time to elapse before it is done. In general, when a predetermined condition (for example, winning in a V zone provided in the variable winning ball device) is not satisfied at the time when the variable winning ball device is closed, the big hit game state ends. However, it is rare that the predetermined condition is not satisfied when the variable winning ball device is closed.

[0005]

If, for example, the variable winning prize device winning upper limit number is 10, the number of rounds is 16, and the number of prize balls is 15, the number of payouts during the big hit game is as follows. It is decided to 2400. For a player, when a big hit occurs, a stable number of obtained balls can be expected, but on the other hand, when a big hit occurs, the number of balls to be obtained during the big hit game can be predicted, so that the expectation of the player is diminished and the game is interesting. There is a problem that lacks.

[0006] The present invention has been made to solve such a problem, and it is possible to provide a predetermined game value when the display result of the identification information has a predetermined specific display mode. In such a case, an object of the present invention is to provide a ball game machine capable of performing a more interesting game by further improving the player's sense of expectation.

[0007]

If the hit ball wins in the specific winning area during the opening of 0 and is detected by the V count sensor 22, a continuation right is generated and the opening and closing plate 20 is opened again. The generation of the continuation right is permitted a predetermined number of times (for example, 15 rounds).

If the combination of images in the image display section 9 at the time of stoppage is a combination of big hit symbols accompanied by a probability change, the probability of the next big hit increases. That is, a high probability state, which is more advantageous for the player, is obtained. Also, when the stop symbol on the variable display 10 is a predetermined symbol (hit symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the high probability state, the probability that the stop symbol on the variable display 10 hits the symbol is increased, and the opening time and the number of times the variable winning ball device 15 is opened are increased.

And an information output circuit 64 for outputting the information.

A hit ball firing device 3 for hitting and firing a game ball
4 is driven by a drive motor 94 controlled by a circuit on the emission control board 91. Then, the driving force of the driving motor 94 is adjusted according to the operation amount of the operation knob 5. The operation knob 5 is provided with a touch sensor 93, and when a player touches the operation knob 5, a current flows and the contact of the operator is detected. In this state, the circuit on the firing control board 91 is controlled so that the hit ball is fired at a speed corresponding to the operation amount of the operation knob 5.

The basic circuit 53 includes a ROM 54 for storing a game control program and the like, a RAM 55 used as a work memory, a CPU 56 for performing a control operation according to a control program, and an I / O port unit 57. The ROM 54 and the RAM 55 may be built in the CPU 56 in some cases.

FIG. 5 is an explanatory view showing 15 types of symbols which are sequentially displayed on the image display section 9 of the variable display device 8 in response to a hit ball winning the starting winning opening 14. The image display section 9 has three symbol display areas of “left”, “middle”, and “right”, each of which has a name “n” from a symbol “0” as shown in FIG. Are sequentially displayed, and the symbol indicated by the name “n” is displayed next to the symbol indicated by the name “n”.

When a predetermined time elapses after the start of the variable display, the three symbols stop. If the combination of the stopped symbols is the same for each symbol, a big hit occurs. Also, when the combination of stop symbols is a combination of specific symbols,
A big hit occurs and the state becomes highly probable. In addition,
In this embodiment, the middle symbol is finally determined. In the state of high probability, the probability of the next big hit is increased, the time required for the symbol to be determined after the variable display 10 starts variable display is shortened, and the variable prize is generated when the variable display 10 hits. The open state of the ball device 15 is set long. That is, at the time of a high probability, the state becomes extremely advantageous for the player.

Next, the operation will be described. FIG. 6 is a flowchart showing the operation of the basic circuit 53 on the main board 31. As described above, this process is started, for example, every 2 ms by the reset pulse generated by the periodic reset circuit 66. When the basic circuit 53 is activated,
First, the basic circuit 53 performs a stack setting process for setting a designated address of a stack pointer (step S1). Next, initialization processing is performed (step S
2). In the initialization processing, the basic circuit 53 determines whether or not the RAM 55 contains an error. If the error is included, the basic circuit 53 performs processing such as initializing the RAM 55.
Then, after performing a process of setting the command code sent to the display control board 80 in a predetermined area of the RAM 55 (Step S3), a process of outputting the command code is performed (Step S4).

Next, a process for transmitting a predetermined command for sound generation and LED lighting control to the sub basic circuit 71 of the illuminated board 35 via the illuminated board command output circuit 62 is performed. A process for transmitting data such as big hit information, start information, probability variation information, etc. to the hall management computer via the H.64 (data output process: step S5). In addition, various abnormality diagnosis processes are performed by the self-diagnosis function provided inside the pachinko gaming machine 1, and an alarm is issued if necessary according to the result (error process: step S6).

Next, a process of updating each counter indicating each random number for determination is performed (step S7). Hereinafter, updating the counter is referred to as counting up or adding random numbers. In this embodiment, as shown in FIG. 7, there are the following random numbers, for example. (1) Random 1: Determines whether or not to generate a big hit (for big hit determination) (2) Random 2-1 to 2-3: For left and right middle out-of-design symbol determination (3) Random 3: Design of big hit (4) Random 4: Determine whether or not to reach at the loss (for reach determination) (5) Random 5: Determine for reach type (for reach operation determination) (6) Random 6: Determines whether to open the special winning opening (for determining the special winning opening) (7) Random 7: Determines the opening time of the special winning opening for each round (for determining the special winning opening time) ( 8) Random 8: Determines the number of possible wins to the special winning opening of each round (for determining the maximum winning opening winning number) (9) Random 9: Determines the number of prize balls when winning in the special winning opening ( (For determining the number of award winning balls) To increase the are also used random other than random numbers (1) to (9).

In step S7, the basic circuit 53
The random number for big hit determination of (1) and the random number for big hit symbol determination of (3) are counted up (addition of 1). That is, they are the random numbers for determination.

Next, the basic circuit 53 performs a special symbol process (step S8). In the special symbol process control, a corresponding process is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to a gaming state. Then, the value of the special symbol process flag is updated during each processing according to the gaming state. Further, a normal symbol process is performed (step S9). In normal symbol processing, 7 segment LE
A corresponding process is selected and executed according to a normal symbol process flag for controlling the variable display device 10 by D in a predetermined order. Then, the value of the normal symbol process flag is updated during each process according to the gaming state. Further, the basic circuit 53 inputs the states of the gate sensor 12, the starting port sensor 17, and the count sensor 23 via the switch circuit 58, and determines whether or not each of the winning openings and the winning devices has been won (step S10). .

The basic circuit 53 further performs processing for updating the display random number (step S11). That is,
The random number for determining the lost symbol in (2), the random number for reach determination in (4), and the random number for reach operation in (5) are counted up (addition of 1). However, random 2-
2 is counted up when a random 2-1 carry occurs. Also, random 2-3 is random 2-
It is counted up when a carry of 2 occurs. Further, in this embodiment, the random numbers for determining the variables related to the special winning opening of (6) to (9) are also updated in the process of step S11.

The basic circuit 53 performs signal processing with the award ball substrate 37 (step S12). That is, it is determined whether or not a winning data signal is output from the prize ball substrate 37, and when a predetermined condition is satisfied, the prize ball substrate 3
7 to output a prize ball number signal. The payout control microcomputer mounted on the prize ball board 37 drives the ball payout device 97 according to the prize ball number signal.

Thereafter, the basic circuit 53 repeats the display random number updating process in step S13 until the next reset pulse is given from the periodic reset circuit 66. That is, 1 is added to the value of each random number. Note that what is added here is, as shown in FIG.
Of the random numbers in (8), the random numbers for determining the outlying symbols in (2),
A random number for reach determination in (4), a random number for reach operation determination in (5), and a random number for determining variables related to the special winning opening in (6) to (9). Again, random 2-
2 is counted up when a random 2-1 carry occurs, and random 2-3 is counted up when a random 2-2 carry occurs.

Next, a method of determining a symbol variably displayed on the image display section 9 based on a winning in the starting winning opening 14 (starting winning) will be described with reference to flowcharts of FIGS. FIG. 8 shows a process for determining that the hit ball has won the start winning opening 14, and FIG. 9 shows a process for determining a variable display stop symbol on the image display device 9. Also,
FIG. 10 is a flowchart illustrating the big hit determination process.

When the hit ball wins the starting winning port 14 provided on the game board 6, the starting port sensor 17 is turned on. In the switch processing of step S10, the basic circuit 53
Determines that the starting port sensor 17 has been turned on via the switch circuit 58 (step S41). If it is detected that the switch has been turned on, it is confirmed whether or not the number of stored start winnings has reached the start memory upper limit value of 4 (step S4).
2). If the start winning prize memory number has not reached the start memory upper limit value, the starting prize memory number is increased by 1 (step S43),
The value of the random number for jackpot determination is extracted. Then, the extracted random numbers are stored in the random number value storage areas provided corresponding to the respective start winning prize storage numbers n (n = 1, 2, 3, 4) (step S44). If the number of start winning memories has reached the start memory upper limit value, the processes of steps S43 and S44 are not performed.

The basic circuit 53 performs the processing shown in the flowchart of FIG. 9 when it becomes possible to start the variable display of the image display section 9. First, the value of the number of memorized start winnings is confirmed (step S50). If the start winning prize memory number is not 0, the value stored in the random number storage area corresponding to the start prize storing number = 1 is read out (step S51), the value of the starting prize storing number is reduced by 1, and The value of the random number value storage area is shifted (step S52). In other words, the value stored in the random number value storage area corresponding to the number of start winning memory = n (n = 2, 3, 4) is calculated as follows:
1 is stored in the random number value storage area corresponding to 1.

Then, the basic circuit 53 proceeds to step S51.
Is determined based on the value read in step 2, ie, the value of the extracted random number for jackpot determination (step S53). In this embodiment, the big hit determination random number has a value in the range of 0 to 256. Then, as shown in FIG. 10, when the probability is low, for example, if the value is 3, it is determined to be a big hit, and if it is any other value, it is determined to be out. When the probability is high, for example, the value is 3,
If it is any of 7, 79, 103, 107, it is determined to be a big hit, and if it is any other value, it is determined to be out.

When it is determined that a big hit has occurred, the basic circuit 5
3 determines the stop symbol based on the value of the big hit symbol determination random number (random 3). Here, when the limiter is operating, a stop symbol is determined from a table that does not include a special symbol (probable change symbol) that causes a high probability state (steps S54 and S56). The limiter is for restricting the occurrence of the jackpot due to the probable symbol continuously, that is, the continuation of the continuous high probability state. For example, if the high probability state continues four times in a row, the limiter is activated. Therefore, in the limiter operating state, the stop symbol is determined from the table that does not include the special symbol in which the probability change is performed.

If the limiter is not operating, a stop symbol is determined from a table including all symbols (step S5).
4, S55). In this embodiment, the probable design is shown in FIG.
As shown in 1, "three", "three", "three", "five",
"Five", "Five", "Seven", "Seven", "Seven", "N",
It is assumed that there are four types, "n" and "n". Therefore, in the limiter operating state, a combination of the stop symbols that does not include such four types of positively varying symbols is determined.

Further, the basic circuit determines a reach type according to the value of the random number 5 (step S74), and sets whether or not to make a big hit, a symbol in the case of a big hit, and a reach type in a predetermined storage area (step S74). S75). The storage area is provided in the RAM 55 of the basic circuit 53.

If it is determined in step S53 that there is a deviation, the basic circuit 53 determines whether or not to reach (step S59). For example, when the value of the reach determination random number shown in FIG. 7 is any one of 0 to 104, it is determined to reach. When it is decided to reach, the basic circuit decides a stop symbol. In this embodiment, the left and right symbols are determined according to the value of the random 2-1 (step S60). Also, random 2-2
The middle symbol is determined according to the value of (step S61). Here, if the determined middle symbol matches the left and right symbols, the symbol corresponding to the value obtained by adding 1 to the value of the random number corresponding to the middle symbol is determined as the middle symbol, so that it does not match the big hit symbol. I do.

Further, the basic circuit determines a reach type according to the value of the random number 5 (step S62). Then, “reach”, reach symbol, and reach type are set in a predetermined storage area (step S63). If the lottery result in step S59 is out of place, it is set that it is out of place in the predetermined storage area (step S64).

FIG. 12 is a flowchart showing an example of a special symbol processing program in the basic circuit 53. The special symbol process shown in FIG. 12 is a specific process of step S8 in the flowchart of FIG. When performing the special symbol process processing, the CPU 56 of the basic circuit 53 performs any one of steps S300 to S309 shown in FIG. 12 according to the internal state. In each process, the following processes are performed.

Special symbol change waiting process (step S30)
0): The start winning port 14 (in this embodiment, the winning port of the variable winning ball device 15) is hit and the start port sensor 17 is turned on. Special symbol determination processing (step S301): When the start-up opening sensor 17 is detected to be on, it is determined whether to make a jackpot or a loss according to the value of the special symbol determination random number. Stop symbol setting process (step S302): The stop symbols of the left and right middle symbols are determined according to the value of the special symbol random number.

Reach operation setting processing (step S30)
3): Whether or not to perform the reach operation is determined according to the value of the reach determination random number, and the variation mode of the reach operation is determined according to the value of the reach random number.

All symbols change start processing (step S30)
4): The image display unit 9 is controlled so that all symbols start to change. When a background or a character is also displayed on the image display unit 9, control is performed so that display control command data corresponding to the background or character is transmitted to the display control board 80. All symbols stop waiting process (step S305): After a predetermined time has elapsed, control is performed so that all symbols displayed on the image display unit 9 are stopped. In addition, control is performed such that the left and right symbols are stopped at a predetermined timing until the timing of stopping all symbols, and display control command data corresponding to a background or a character displayed on the image display unit 9 is appropriately displayed on the display control board 80. Control to be sent to

Big hit display processing (step S306):
If the stop symbol is a combination of jackpot symbols,
The display control command data of the jackpot display is controlled to be sent to the display control board 80, and the internal state is updated so as to shift to step S307. If not, the internal state is updated to shift to step S309. The combination of the big hit symbols is a combination in which the right and left middle symbols are aligned. The circuit of the game control board 80 displays a big hit on the image display unit 9 according to the display control command data. The jackpot display is made to notify the player of the occurrence of the jackpot. Big winning opening opening process (step S307): Control for opening the big winning opening is started. Processing during opening of the special winning opening (step S308): The display control command data of the special winning opening round display is displayed on the display control board 8.
Control to send to 0, processing for confirming establishment of the closing condition of the special winning opening, and the like are performed. Jackpot end processing (step S309): A display for notifying the player that the jackpot gaming state has ended is performed. When the display is completed, the internal flags and the like are returned to the initial state, and the internal state is updated so as to shift to step S300.

In accordance with the processing of each of the above steps, the module that performs processing for transmitting display control command data in the game control program outputs the corresponding display control command data to the output port and outputs a strobe signal to the output port. Output to In this embodiment, the special winning opening opening process of step S307 and the special winning opening process of step S308 are executed for each round.

The flowchart shown in FIG. 9 focuses on the process of determining a variable display stop symbol in the image display device 9. However, the determination in step S50 in FIG. The process is executed in step S300 in the process, and the processes in steps S51 to S53 in FIG. 9 are executed in step S301 in the special symbol process process. Further, the processing of steps S55 to S61 in FIG. 9 is executed in step S302 in the special symbol process processing. Then, the processing of steps S62 to S64 in FIG. 9 is executed in step S303 in the special symbol process processing.

FIG. 13 is a flowchart showing the processing of step S307 (large winning opening opening start processing) in the special symbol process processing. In the special winning opening opening process, the basic circuit 53 first checks whether or not a big hit game is being played (step S101). Whether or not a big hit game is being performed is confirmed by a big hit game flag. If the big hit is not being played, that is, if the process of step S307 is performed for the first time after the occurrence of the big hit (the first round has not been started yet), the big hit flag is set (step S102).

Then, a value of random 6 for determining whether or not to open the special winning opening is extracted (step S10).
3). If the value of the extracted random 6 is a value indicating opening of the special winning opening, a special winning opening opening flag is set (steps S104 and S105). FIG. 14 shows the value of random 6 used in this embodiment and the opening of the special winning opening.
It is explanatory drawing which shows the correspondence with non-opening. The random number 6 can take a value of 1 to 114 as shown in FIG. 7, but the extracted value is 1, 9, 11, 19, 21, 29, 31, 39,
If any of 41, 49, 51, 59, 61, it is determined not to open the special winning opening. If the value is any other value, it is determined to open the special winning opening.

Further, the basic circuit 53 increments the value of the counter for counting the number of rounds by one (step S10).
6). Then, the three symbols on the image display unit 9 are changed again (step S107). Specifically, the basic circuit 53 performs control to send display control command data to the display control board 80 such that all symbols start to change.

If a big hit game is being played in step S101, the basic circuit 53 checks whether or not a symbol change is being performed on the image display section 9 (step S110). If the symbol is changing, it is confirmed whether or not it is time to stop the symbol (step S11).
1). The stop timing is, for example, five seconds after the symbol change is started in step S107. If the stop timing has come, the basic circuit 53 performs control to send display control command data instructing stop of all symbols to the display control board 80 (step S112). Here, the stop symbol shown in FIG. 14 is also instructed by the display control command data according to the value of random 6 extracted in step S103. That is, the value of the extracted random 6 is 1, 9, 11, 19, 21, 29, 3
If any of the symbols 1, 39, 41, 49, 51, 59 and 61 is selected, an instruction is given to set the stop symbol of the middle symbol to a symbol shifted from the symbol when the big hit occurred. When the value of the extracted random 6 is any other symbol, an instruction is given so that the combination of the stopped symbols matches the symbol combination at the time of the occurrence of the big hit.

FIG. 15 is an explanatory diagram showing an example of a combination of stop symbols at the time of occurrence of a big hit and an example of a stop symbol of each change during the big hit game. According to the control described above,
As shown in FIG. 15A, assuming that a big hit occurs in a combination of “three”, “three”, and “three”, and the value of random 6 extracted in step S103 is “1”, step S112 As shown in FIG. 15 (B), the symbols stop in a combination of "3", "4", and "3".

When the special winning opening flag is set, the basic circuit 53 resets the special winning opening flag (steps S113 and S114). ), The process flag is set to a value corresponding to the special winning opening processing (step S115). If the special winning opening flag is not set, it is checked whether or not the counter value has reached the opening upper limit (step S1).
16) If it has reached, the big hit gaming flag is reset (step S117), and the process flag is set to a value corresponding to the big hit end processing so that the special symbol process processing shifts to the big hit end processing (step S309). It is set (step S118). If the value of the counter has not reached the open upper limit value, the process ends. Then, when the process of step S307 is performed next (after 2 ms), the process of step S103 is performed through the processes of step S101 and step S110 to perform a lottery to determine whether or not to open the special winning opening in the next round. The processing is executed. The open upper limit is, for example, 16.

The fact that the symbol is not changing in step S110 means that the interval is between rounds. Therefore, the basic circuit 53 performs the processing after step S103 to determine whether to start the next round. It should be noted that although a certain period of time is allowed after the end of the round until the next round is started, this is omitted in FIG.

According to this embodiment, whether or not to open the special winning opening during the big hit game is determined each time.
Then, the symbols fluctuate in the image display section 9, and the fluctuated symbols stop according to the lottery result. In this embodiment, when it is determined that the big winning opening is to be opened as a result of the lottery, the stop symbol is controlled so as to match the stop symbol at the time of occurrence of the big hit. When it is determined not to open the special winning opening, the stop symbol is controlled so as to deviate from the stop symbol when the big hit occurs. Therefore, the player recognizes that it is determined whether or not the special winning opening is opened according to the result of the change of the symbol. As described above, during the big hit game, if it is determined by lottery each time whether or not the special winning opening is opened, the player pays attention to the result of the symbol change reflecting the lottery result. That is, it is possible to improve the interest given to the player by changing the big hit game state.

FIG. 16 is a flowchart showing the processing of step S308 (processing during opening of the special winning opening) in the special symbol process processing. In the processing during opening of the big winning opening,
The basic circuit 53 first checks whether or not the special winning opening is open (step S201). Whether or not the special winning opening is being opened is confirmed by an opening flag. If it is not open, the open flag is set (step S202), and control for opening the opening / closing plate 20 is performed (step S203). Specifically, a flag instructing to open the opening / closing plate 20 is set. For example, in step S5 (data output processing) shown in FIG. 6, if the flag is set, the opening / closing plate 20 is opened. Solenoid 21 is turned on. Then, the basic circuit 53 sets an open time in the timer (Step S204). In the above-described embodiment, the opening time is a fixed value (for example, 29 seconds). However, in some embodiments described later, the opening time may be a variable.

If the open flag is set in step S201, the basic circuit 53 checks whether the timer has expired (step S2).
10). If the time is not up, open / close plate 20
It is checked whether or not the number of times that the count sensor 23 for detecting the winning from the player has reached the winning upper limit number (step S211). In the above-described embodiment, the winning upper limit number is a fixed value (for example, 10), but in some embodiments described later, the winning upper limit number may be a variable.

If the time is up in step S210, or if the maximum number of winnings has been reached in step S211, control is performed to close the open / close plate 20 and the open flag is reset (step S212). ). Then, it is checked whether or not the value of the counter for counting the number of times of opening the special winning opening (including the number of times determined not to be opened by random 6) has reached the opening upper limit value (step S213). While resetting the big hit game in progress flag (step S21)
6), the process flag is set to a value according to the jackpot ending process so that the special symbol process process shifts to the jackpot ending process (step S309) (step S21).
7).

If the value of the counter has not reached the open upper limit value, it is checked whether or not the V count sensor 22 was turned on during opening (step S214). If it is on, the process flag is set to a value according to the special winning opening opening process so that the next round is started after the interval (step S215). If the V count sensor 22 is not turned on during opening, the continuation right does not occur, so the big hit game in progress flag is reset (step S216), and the process flag is set to a value according to the big hit end processing (step S216). S217). The processing during opening of the special winning opening shown in FIG. 16 is also used in each embodiment described later.

FIG. 17 is a flowchart showing the process of step S307 (large winning opening opening process) of the special symbol process process in another embodiment. In this case, the number of rounds during the jackpot game is fixed, but the winning time opening time of each round is randomly selected each time. The basic circuit 53 first checks whether or not a big hit game is being played (step S301). If the big hit game is not being performed, that is, if the process of step S307 is performed for the first time after the occurrence of the big hit, the big hit game in progress flag is set (step S302).

Then, a value of random 7 for determining the opening time is extracted (step S303). The release time is set according to the value of the extracted random number 7 (step S
304). FIG. 18 is an explanatory diagram showing the correspondence between the value of random 7 used in this embodiment and the release time. The random number 7 can take a value of 16 to 28 as shown in FIG. 7, but the extracted value is the open time. In addition, as shown in FIG. 18, a stop symbol of the symbol change is determined according to the extracted value. Further, the basic circuit 53 increments the value of the counter for counting the number of rounds by one (step S30).
5). Then, the three symbols on the image display unit 9 are changed again (step S306).

If a big hit game is being played in step S301, the basic circuit 53 checks whether or not a symbol change is being performed on the image display section 9 (step S310). If the symbol is changing, it is checked whether or not it is time to stop the symbol (step S31).
1). If the stop timing is reached, the basic circuit 53
Performs control to send display control command data instructing stop of all symbols to the display control board 80 (step S3).
12). Here, the stop symbol shown in FIG. 18 is also instructed by the display control command data according to the value of the random 7 extracted in step S303. For example,
If the value of the random number 7 extracted in step S303 is “16”, the symbol stops in a combination of “1”, “1”, and “1”. And the basic circuit 53
The process flag is set to a value corresponding to the special winning opening processing (step S31) so that the special symbol processing proceeds to the special winning opening processing (step S308).
3).

The fact that the symbol is not changing in step S310 means that the interval is between rounds. Therefore, the basic circuit 53 performs the processing after step S303 to determine the opening time of the next round. It should be noted that although a certain period of time is required after the end of the round until the next round is started, this is omitted in FIG.

According to this embodiment, in each round during the big hit game, a special winning opening time is randomly selected each time. Then, the symbol fluctuates in the image display unit 9,
The changed symbol stops according to the lottery result. Therefore, the player recognizes that the opening time of the special winning opening is determined according to the result of the change of the symbol. As described above, during the big hit game, the winning time opening time in each round is determined by the lottery each time, so the player pays attention to the result of the symbol change reflecting the lottery result. That is, in the big hit game state, the interest given to the player can be improved.

FIG. 19 is a flowchart showing the process of step S307 (large winning opening opening start process) of the special symbol process process in still another embodiment. In this case, the number of rounds during the jackpot game is fixed,
The maximum number of winnings in the big winning opening of each round is drawn each time. The basic circuit 53 first checks whether or not a big hit game is being played (step S401). If a big hit game is not being played, a big hit game in progress flag is set (step S402).

Then, a value of random 8 for determining the winning upper limit number is extracted (step S403). The upper limit number is set according to the value of the extracted random number 8 (step S404). FIG. 20 is an explanatory diagram showing the correspondence between the value of random 8 used in this embodiment and the winning upper limit number. The random number 8 can take a value of 6 to 10 as shown in FIG. 7, but the extracted value becomes the winning upper limit number. In addition, as shown in FIG. 20, the stop symbol of the symbol change is determined according to the extracted value. Further, the basic circuit 53 increments the value of the counter for counting the number of rounds by one (step S405). Then, the three symbols on the image display unit 9 are changed again (step S406).

If a big hit game is being played in step S401, the basic circuit 53 checks whether or not the symbol change is being performed on the image display section 9 (step S410). If the symbol is changing, it is checked whether or not it is time to stop the symbol (step S41).
1). If the stop timing is reached, the basic circuit 53
Performs control to send display control command data instructing stop of all symbols to the display control board 80 (step S4).
12). Here, the stop symbol shown in FIG. 20 is also instructed by the display control command data according to the value of the random number 8 extracted in step S403. For example,
If the value of the random number 8 extracted in step S403 is “6”, the symbol stops in a combination of “6”, “6”, and “6”. Then, the basic circuit 53 determines that the special symbol process process is a special winning opening opening process (step S
308), the process flag is set to a value corresponding to the special winning opening processing (step S41).
3).

The fact that the symbol is not changing in step S410 means that the interval is between rounds. Therefore, the basic circuit 53 performs the processing from step S403 onward to determine the winning number in the next round. It should be noted that although a certain period of time is allowed after the end of the round until the next round is started, this is omitted in FIG.

According to this embodiment, in each round during the big hit game, the upper limit number of winnings to the special winning opening is randomly selected each time. Then, the symbols fluctuate in the image display section 9, and the fluctuated symbols stop according to the lottery result.
Therefore, the player recognizes that the maximum winning number is determined according to the result of the symbol change. Thus, during the big hit game, the maximum number of winnings in each round is
Each time the determination is made by the lottery, the player pays attention to the result of the symbol change reflecting the lottery result. That is,
There is provided a gaming machine which can attract a player strongly by symbol fluctuation even in a big hit gaming state.

FIG. 21 is a flowchart showing the processing of step S307 (large winning opening opening start processing) of the special symbol processing in still another embodiment. In this case as well, the number of rounds during the jackpot game is fixed, but in each round, the number of prize balls at the time of winning in the special winning opening is randomly selected at the start of each round. Basic circuit 53
First, it is determined whether or not a big hit game is being played (step S501). If it is not during the big hit game, a big hit game in progress flag is set (step S502).

Then, a value of random 9 for determining the number of prize balls is extracted (step S503). The number of prize balls is set according to the value of the extracted random 9 (step S50).
4). FIG. 22 is an explanatory diagram showing the correspondence between the value of random 9 and the number of winning balls used in this embodiment. The random number 9 can take a value of 10 to 15 as shown in FIG.
The extracted value is the number of prize balls. In addition, as shown in FIG. 22, the stop symbol of the symbol change is determined according to the extracted value. Further, the basic circuit 53 increments the value of the counter for counting the number of rounds by one (step S505). Then, the three symbols on the image display unit 9 are changed again (step S506).

If a big hit game is being played in step S501, the basic circuit 53 checks whether or not the symbol change is being performed on the image display section 9 (step S510). If the symbol is fluctuating, it is checked whether or not it is time to stop the symbol (step S51).
1). If the stop timing is reached, the basic circuit 53
Performs control to send display control command data instructing stop of all symbols to the display control board 80 (step S5).
12). Here, the stop symbol shown in FIG. 22 is also instructed by the display control command data according to the value of the random number 9 extracted in step S403. For example,
If the value of the random number 9 extracted in step S503 is “15”, the symbol stops in a combination of “seven”, “seven”, and “seven”. And the basic circuit 53
The process flag is set to a value corresponding to the special winning opening processing (step S51) so that the special symbol processing proceeds to the special winning opening processing (step S308).
3).

The fact that the symbol is not being changed in step S510 means that the interval is between rounds. Therefore, the basic circuit 53 performs the processing after step S503 in order to determine the number of winning balls in the next round. It should be noted that although a certain period of time is left after the end of the round until the next round is started, this is omitted in FIG.

According to this embodiment, at the start of each round during the big hit game, the number of prize balls at the time of winning the big winning port in the round is randomly selected each time. Then, the symbols fluctuate in the image display section 9, and the fluctuated symbols stop according to the lottery result. Therefore, the player recognizes that the number of prize balls has been determined in accordance with the symbol variation result. As described above, during the big hit game, the number of prize balls in each round is determined by lottery each time, so the player pays attention to the result of the symbol change reflecting the lottery result. That is, a gaming machine that can attract a player strongly by symbol fluctuation even in a big hit gaming state is provided.

FIG. 23 is a flowchart showing an example of the payout control of the basic circuit 53. The basic circuit 53 receives the winning data signal from the winning ball substrate 37 (step S60).
1) It is checked whether the starting port sensor 17 has been turned on (step S602). When the starting port sensor 17 is turned on, that is, when there is a winning in the starting winning port 14, the winning ball number signal to the winning ball board 37 is set to 6 (step S603). When the count sensor 23 is on (step S604), that is, when there is a prize in the special winning opening (a prize through the opening and closing plate 20), the prize ball number signal is changed to the value of the extracted random 9 The number is determined according to the number (step S605). Otherwise, the prize ball number signal is set to 10 (step S606).

With the above processing, six prize ball substrates 37 are obtained when a hit ball is won in the starting winning opening 14, and ten prize balls are obtained when hit balls are won in the winning opening other than the starting winning opening 14 and the big winning opening. When there is a prize in the mouth, the control of paying out a prize ball in a number according to the lottery result is performed.

In each of the above-described embodiments, in each round during the jackpot game, whether or not to open the special winning opening, the opening time of the special winning opening, the maximum number of winnings to the special winning opening, or the special winning The number of prize balls for the winning in the mouth is selected by lottery, symbols are changed, and a stop symbol corresponding to the lottery result is displayed. In other words, for the player, depending on the stop symbol of the fluctuating symbol, whether or not to open the special winning opening, the opening time of the special winning opening,
The upper limit number of winnings in the special winning opening or the number of prize balls for winning in the special winning opening is presented as determined. But,
Each lottery may be performed in combination. For example, in each round during the jackpot game, a lottery is performed to determine whether or not to open the special winning opening, and a lottery is required to determine whether or not to open the special winning opening. The maximum number of winnings may be determined by lottery. Alternatively, a lottery may be performed to determine whether or not to open the special winning opening, and the number of prize balls for winning the special winning opening may be selected.

FIG. 24 is a flow chart showing an example in which the lottery opening is randomly selected and the opening time of the special winning opening is randomly selected. In this case, in step S307 (special winning opening opening process) in the special symbol process process, the basic circuit 53 first checks whether or not a big hit game is being played (step S701). If a big hit game is not being played, a big hit game in progress flag is set (step S702).

Then, a value of random 6 for determining whether or not to open the special winning opening is extracted (step S 70).
3). If the value of the extracted random 6 is a value indicating opening of the special winning opening, a special winning opening opening flag is set (steps S704 and S705). As shown in FIG. 14, the extracted values are 1, 9, 11, 19, 21, 29,
If it is any of 31, 39, 41, 49, 51, 59, 61, it is determined not to open the special winning opening. If the value is any other value, it is determined to open the special winning opening. Further, the basic circuit 53 increments the value of the counter for counting the number of rounds by one (step S).
706). Then, the three symbols on the image display unit 9 are changed again (step S707).

If a big hit game is being played in step S701, the basic circuit 53 checks whether or not a symbol change is being performed on the image display section 9 (step S710). If the symbol is changing, it is checked whether or not it is time to stop the symbol (step S71).
1). If the stop timing is reached, the basic circuit 53
Performs control to send display control command data instructing stop of all symbols to the display control board 80 (step S7).
12). Here, the stop symbol shown in FIG. 14 is also instructed by the display control command data according to the value of random 6 extracted in step S703.

Next, the basic circuit 53 checks whether or not the special winning opening flag is set (step S7).
13). If the special winning opening flag is set, it is confirmed whether or not the symbol stop is the first time (step S714). In this embodiment, a symbol change is performed to determine whether or not to open the special winning opening as the first symbol change, and if it is determined to open the special winning opening, the second symbol is changed. A symbol change for determining the opening time is performed as the change.

Therefore, when the first symbol change is completed, a value of random 7 for determining the opening time is extracted (step S731). The release time is set according to the extracted value of the random number 7 (step S731). The random number 7 can take a value of 16 to 28 as shown in FIG. 7, but the extracted value is the open time. In addition, as shown in FIG. 18, a stop symbol of the symbol change is determined according to the extracted value. Then, the basic circuit 53 causes the three symbols of the image display unit 9 to change again (step S732).

If the second symbol change has been completed in step S714, the special winning opening opening flag is reset (step S740), and the special symbol process process is executed during the special winning opening process (step S308). ), The process flag is set to a value corresponding to the processing during opening of the special winning opening (step S741).

The fact that the special winning opening flag has not been set in step S713 means that it has been decided not to open the special winning opening in the lottery based on the random 6 extracted in step S703. Therefore, it is not necessary to select the opening time. In that case, it is confirmed whether or not the value of the counter has reached the opening upper limit value (step S720). If it has reached, the big hit game in progress flag is reset (step S721), and the special symbol process process ends. Processing (Step S309)
The process flag is set to a value corresponding to the big hit end processing so as to shift to (step S722). If the value of the counter has not reached the open upper limit value, the process ends. Then, when the process of step S307 is performed next (after 2 ms), steps S701 and S7 are performed.
Through the processing of step 10, the processing of step S703 is executed to perform a lottery on whether or not to open the special winning opening in the next round.

As described above, according to this embodiment,
For each round, the player determines whether or not the special winning opening is opened according to the result of the first symbol change, and the opening time of the special winning opening is determined according to the result of the second symbol change. To recognize. Therefore, the player expects whether or not the special winning opening will be opened in accordance with the symbol change for each round, and also expects that the opening time will be determined to be long in accordance with the symbol change performed subsequently. Therefore, the gaming machine according to this embodiment can further improve the expectation of the player.

In this embodiment, by combining the processing shown in FIG. 13 and the processing shown in FIG. 17, it is determined at each round during the jackpot game whether or not the large winning opening is opened. In addition, an example was shown in which the opening time of the special winning opening was randomly selected. Similarly, by combining the processing shown in FIG. 13 with the processing shown in FIG.
It is possible to implement a process of performing a lottery to determine whether or not to open the special winning opening and a lottery of the maximum number of winnings to the special winning opening. Also, by combining the processing shown in FIG. 13 and the processing shown in FIG. 21, it is possible to perform a lottery to determine whether or not to open the special winning opening and to perform a lottery process for selecting the number of prize balls for winning in the special winning opening. can do.

As described above, according to each of the above-described embodiments, for each round during the jackpot game, whether or not to open the special winning opening, the opening time of the special winning opening, and to the special winning opening The maximum number of winnings or the number of prize balls for winning in the grand prize mouth is determined by lottery, so that the number of balls to be played in each of the big hit games is different. Players expect the occurrence of stop symbols that will increase the number of balls that can be acquired,
The expectation of the player during the jackpot game is higher than that of the conventional gaming machine. That is, the gaming machine according to the present invention
It has a fresh taste in which the player's expectation is improved with a new game characteristic in which the number of balls to be played differs for each big hit.

In each of the above embodiments, the image display unit 9 using a CRT for variably displaying a plurality of types of symbols is provided.
Although the description has been given of the case of using a variable display device, a case where a variable display device using an LCD may be used. Furthermore, the present invention can be applied to a video-type pachinko gaming machine in which the entire board surface is composed of video.

[0089]

As described above, according to the present invention, a ball game machine can be changed to a variable prize ball device by using a change in identification information displayed on a variable display section after a specific display mode is attained. Since the lottery is configured so that the game value given by opening is variable, when the display result of the identification information becomes a predetermined specific display mode, each time a specific display mode occurs There is an effect that a gaming machine with a freshness and rich in game characteristics, in which the value acquired by the player is different, is provided. In the case where the identification information is changed before each opening of the variable winning ball apparatus, and whether or not to perform the opening each time is determined by lottery, each time a specific display mode occurs. The number of times the variable prize ball device is opened is different from that of the first embodiment, so that it is possible to provide a gaming machine that can increase the player's expectation and play a more interesting game.
