DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko game machine or a coin game machine, and more particularly to a game machine including 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 gaming machine in which a predetermined game value can be given when the display mode is changed to the display mode.

[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.

Some of such gaming machines have a so-called probability variation function that increases the probability of a big hit when a predetermined condition is satisfied. In the high-probability state (probable change state), the jackpot occurrence probability is increased, but in general, a state that is extremely advantageous for a player whose base (the number of prize balls per 100 hit balls) is also increased so as not to reduce the number of balls held by the player. Becomes In the probable change state, the base is generally set to about 100, but in order to maintain such a value, the probability of hitting by the ordinary symbol displayed on the display provided in the gaming area of the gaming machine is increased, or the ordinary symbol is increased. For example, the opening time of the electric accessory (electric tulip) based on the hit caused by the contact may be lengthened.

[0005] Fig. 16 shows a normal pattern (for example, 00-19).
FIG. 7 is a timing chart showing a state in which an electric tulip is opened when the stop number is a hit number. FIG. 16A shows a state at a low probability, and FIG. 16B shows a state at a high probability. FIG.
As shown in (A), at the time of low probability, the ordinary symbol fluctuates for 28 seconds when the ordinary symbol variation start condition is satisfied, and the electric tulip is opened for 0.5 seconds when a hit number is displayed when the variation is stopped. Also, as shown in FIG. 16B, at the time of a high probability, if the ordinary symbol change start condition is satisfied, then 5.
When the symbol fluctuates for one second and the hit number is displayed when the fluctuation stops, the electric tulip is opened for 1.6 seconds and 3.
After 5 seconds of closing, the electric tulip is again 1.6
Open for seconds. In the example shown in FIG. 16, the establishment of the normal symbol change start condition is an ON of a gate sensor based on the passage of a gate provided in a game area through a hit ball.

[0006] Whether or not the stop number of a normal symbol is a winning number is determined based on the value of a random number for normal symbol determination. For example, as shown in FIG.
If the value of the normal symbol determination random number that can take a value of 19 is 3, it is determined to be a hit, and if it is any other value, it is determined to be a loss. In addition, at the time of a high probability, a hit is usually made when the value of the random number for symbol determination is an odd number, and a hit is made when the value is an even number.

[0007]

As described above, in the conventional gaming machine, in the high probability state, it is possible to increase the probability of hitting the ordinary symbol which causes the open state of the electric tulip, in which the hit ball is easy to win, By increasing the opening time and the number of times of opening the electric tulip at the time of hitting, or shortening the fluctuation period of the ordinary symbol, a state where the electric tulip can be more easily won than in the case of low probability is generated. With such control, the base is kept at a high value of about 100 at the time of high probability.

An object of the present invention is to provide a gaming machine capable of minimizing a loss of a player in a special game state by maintaining a high value in a special game state by a method different from the conventional method described above. Aim.

[0010] In addition to or independently of such a configuration, the opening / closing control means may control the value payout ratio (so-called base) to a predetermined value in the special gaming state. In accordance with the winning situation, when there is a winning, the opening and closing control of the electric accessory is established to satisfy the condition for starting the change of the identification information. In addition, in the gaming machine, in addition to or independently of the above-described configuration, in the special gaming state, the opening / closing control unit sets the upper limit of the number of storage units in the storage unit that stores the establishment of the condition for starting the change.

When a hit ball enters the starting winning opening 14 and is detected by the starting opening sensor 17, the symbols in the image display section 9 start rotating if the symbols can be changed. If it is not possible to start changing the symbol, the start winning memory is increased by one. The start winning memory will be described later in detail. The rotation of the image in the image display unit 9 stops when a certain time has elapsed. If the combination of images at the time of stop is a combination of big hit symbols,
It shifts to a jackpot game state. That is, the opening and closing plate 20 is
The release is performed until a predetermined time (for example, 29.5 seconds) elapses or a predetermined number (for example, 10) of hit balls wins, whichever comes first. When a hit ball wins in the specific winning area while the opening and closing plate 20 is being opened 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, 16 rounds).

If the combination of images in the image display unit 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.

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, and an information output circuit is also provided. 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 is performed (data output process: step S5). In addition, pachinko machine 1
Various abnormality diagnosis processes are performed by a self-diagnosis function provided inside the device, and an alarm is issued if necessary according to the result (error process: step S6).

Next, a process for 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. FIG. 9 is an explanatory diagram illustrating an example of each random number. Each random number is used as follows. (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 Determining a combination (for determining a big hit symbol = for determining a specific symbol) (4) Random 4: determining whether or not to reach at the time of a loss (for determining a reach) (5) Random 5: determining a reach type (determining a reach operation) For the purpose of enhancing the gaming effect, random numbers other than the random numbers (1) to (5) are also used.

In step S7, the basic circuit 53
The random number for big hit determination of (1) and the random number for specific symbol determination of (3) are counted up (addition of 1). That is,
These 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 a process of updating the display random number (step S11). That is,
The random number for determining a 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
The count is incremented when the carry of the random 2-1 occurs, that is, when the value of the random 2-1 becomes "15" and is returned to "0". Also, random 2-3
Is incremented when a carry of random 2-2 occurs, that is, when the value of random 2-2 becomes "15" and is returned to "0".

The basic circuit 53 performs control to keep the base at the time of high probability at 100 (step S12). Then, the signal processing with the award ball substrate 37 is performed (step S).
13). That is, it is checked whether or not a winning data signal is output from the prize ball substrate 37, and when a predetermined condition is satisfied, a prize ball number signal is output to the prize ball substrate 37. 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 a reset pulse is next 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 of (5), random numbers for determining the outlier symbols of (2),
These are random numbers for reach determination in (4) and random numbers for reach operation determination in (5). Again, random 2-2 is
The random 2-1 is counted up when a carry occurs, and the 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 unit 9 based on a winning in the starting winning opening 14 (starting winning) will be described with reference to flowcharts of FIGS. 7, 8, and 10. . FIG. 7 shows a process for determining that the hit ball has won the start winning opening 14, FIG. 8 shows a process for determining a stop symbol of the variable display of the image display device 9, and FIG.
Indicates a big hit determination process.

When the hit ball wins the starting winning port 14 provided in 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, as shown in FIG. 7 (step S4).
1). If it is detected that the switch has been turned on, it is checked whether or not the number of memorized start winnings has reached the maximum value of 4 (step S42). If the start winning prize storage number has not reached 4, the starting prize storage number is increased by 1 (step S43), and the value of the random number for jackpot determination is extracted (step S44). If the number of stored start winnings has reached 4, the process of increasing the number of stored start winnings is not performed. In other words, in this embodiment, the number of hit balls that have won a maximum of four starting winning openings 17 is stored.

The basic circuit 53 performs the processing shown in the flowchart of FIG. 8 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 jackpot determining means of the basic circuit 53 determines the hit / miss based on the value read in step S51, that is, the value of the extracted random number for jackpot determination (step S53). Here, the big hit determination random number takes a value in the range of 0 to 256.
As shown in FIG. 10, when the probability is low, for example, when the value is “3”, “big hit” is determined, and when the value is any other value, “missing” is determined. When the probability is high, for example, the values are “3”, “7”, “79”, “103”,
If it is any of "107", it is determined as "big hit", and if it is any other value, it is determined as "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, if the limiter is not operating, a stop symbol is determined from a table including all symbols (steps S54 and S55). If the limiter is operating, a stop symbol is determined from a table that does not include a special symbol for which probability variation is performed (step S54,
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.

Further, the basic circuit determines a reach type according to the value of the random number 5 (step S57). If the stop symbol is a probable change symbol, a probable change flag is set (steps S71 and S72), otherwise, the probable change flag is reset (steps S71 and S7).
3). Further, whether or not to make a big hit, a symbol in the case of a big hit, and a reach type are set in a predetermined storage area (step S74). The storage area is the basic circuit 5
3 is provided in the RAM 55.

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 is any 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). In addition, the middle symbol is determined according to the value of the random 2-2 (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 medium symbol is set as the fixed symbol of the medium symbol so as not to match the big hit symbol.

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. 11 is a flowchart showing an example of a specific process of the base stabilization process (step S12) shown in FIG. As shown in FIG.
Checks whether the probability change flag is set (step S121). As described above, the probable change flag is set when the stop symbol is a probable symbol as a result of the symbol change in the image display unit 9. That is, it is set when a high probability state (probable change state) is reached. When the probable change flag is set, the basic circuit 53 outputs the prize ball U
The P flag is set (step S122). If the probability change flag is set, that is, if it is not in the probability change state (low probability state), the winning ball UP flag is reset (step S123).

FIG. 12 is a flowchart showing the specific processing of the winning ball signal processing (step S13) shown in FIG. When the basic circuit 53 receives the winning data signal from the winning ball substrate 37 (step S201), the starting port sensor 1
It is confirmed whether or not 7 has been turned on (step S202).
When the starting port sensor 17 is ON, that is, when there is a winning start, it is checked whether or not the prize ball UP flag is set (step S203). If the prize ball UP flag is not set, the prize ball number signal to the prize ball substrate 37 is set to 6 (step S204), but if it is set, it is set to 15 (step S205). Also,
When the count sensor 23 is on, that is, when there is a prize through the opening and closing plate 20, the prize ball number signal is set to 1
5 (steps S206 and S207), otherwise, the prize ball number signal is set to 10 (step S20).
8).

By the processing shown in FIGS. 11 and 12, the number of winning balls based on the winning start is increased during the probability change. In this example, the number is increased from six to fifteen. Therefore, during probabilistic change, the base is kept at a high value.

FIG. 13 is a flowchart showing another example of the specific processing of the base stabilization processing (step S12) shown in FIG. In this example, the basic circuit 53 feeds back the winning number at the time of the probability change, and opens the variable winning ball device 15 so that the base is maintained at 100.
Specifically, the number of prize balls based on the winning is accumulated so that the base is kept at 100.

As shown in FIG. 13, the basic circuit 53 first checks whether or not the probability change flag is set (step S131). If not set, the process of step S12 ends. If the certainty change flag is set, it is checked whether or not the game ball is currently being fired in the game area (step S132). For example, the launch control board 9
1 use the state of the launch control signal. If the firing control signal is on, the basic circuit 53 can recognize that the game ball has been fired in the game area.

If the game ball is being fired in the game area, the basic circuit 53 checks whether or not the timer 1 is operating (step S133). The timer 1 times out, for example, when it measures 60 seconds after activation. Note that the launch control board 91 is controlled so that the number of game balls that can be launched per minute is less than 100 and close to 100. If the timer 1 is not operating, the timer 1 is started (step S134), and the accumulated number of winning balls is cleared (step S135). The accumulated prize balls will be described later.

When the timer 1 is operating, the basic circuit 5
3 checks whether the time of the timer 1 has expired (step S136). If the time is up, the number of accumulated prize balls is checked (step S137).
If the accumulated prize ball count is smaller than 100-α, the basic circuit 53 performs control to open the variable prize ball device 15 (electric tulip) (step S138). Specifically, here, a flag for instructing release is set, and for example, the data output process shown in FIG. 6 (step S5)
If the flag is set, the solenoid 16 for opening the variable winning ball device 15 is turned on. And a timer 2 for counting the opening time of the variable winning ball device 15.
Is started (step S139). Note that (100-
α in α) may be 0, or may be, for example, about 10 in order to allow a margin for control.

Next, the basic circuit 53 checks whether or not the timer 2 is operating (step S140). If the timer is operating, it is checked whether or not the timer 2 has expired (step S141). If the time is up, control to close the variable winning ball device 15 is performed (step S142). If the game ball has not been fired, the timers 1 and 2 are stopped (steps S150 and S151).

FIG. 14 is a flowchart showing the winning ball signal processing in this example. The basic circuit 53 receives the winning data signal from the winning ball substrate 37 (step S20).
1), it is determined whether or not the starting port sensor 17 has been turned on (step S202). When the starting port sensor 17 is on, that is, when there is a start winning, the winning ball number signal to the winning ball substrate 37 is set to 6 (step S20).
4). At this time, the cumulative prize ball count is set to +6 (step S210). When the count sensor 23 is on, that is, when there is a prize through the open / close plate 20, the prize ball number signal is set to 15 (step S2).
06, S207), and the accumulated number of prize balls is set to +15 (step S211). In other cases, the prize ball number signal is set to 10 (step S208), and the accumulated prize ball number is set to +10 (step S212). By such control, the total number of prize balls based on the winning is accumulated in the cumulative prize ball number.

According to the processing shown in FIGS. 13 and 14, when the base falls below 100 during the probability change, the timer 2
The variable prize ball device 15 is opened for a predetermined period determined by the clocking time of, and the winning state becomes easy. Here, the variable winning ball device 15 is opened for a predetermined period, but the variable winning ball device 15 may be closed when the cumulative number of winning balls exceeds 100 + β. Here, β may be, for example, about 10 in order to allow a margin for control.

In this embodiment, at the time of the probability change,
Higher base (eg 100) than normal (low probability)
, The variable winning prize ball device 15 is controlled so that the degree of the start winning prize differs between the time of the probability change and the normal time. Therefore, instead of the number of accumulated prize balls, the number of start prize balls may be counted, and the variable prize ball device 15 may be opened when the value of the start prize balls falls below a predetermined value.

FIG. 15 is a flowchart showing still another example of the specific processing of the base stabilization processing (step S12) shown in FIG. In this example, the basic circuit 53
Controls the opening of the variable winning ball device 15 so that the starting winning memory is kept at the upper limit value of 4 at the time of the probability change. FIG.
As shown in FIG. 5, the basic circuit 53 first checks whether or not the probable change flag is set (step S16).
1). If not set, the process of step S12 ends. If the probable change flag is set, the number of starting winning memories is checked (step S162). If the number of start winning prizes is 4, the variable winning ball device 15 is closed (step 164). If the number of starting prize is not 4, the variable winning ball device 15 is opened (step 163).

By the processing shown in FIG. 15, the opening of the variable winning ball device 15 is controlled so that the starting winning memory is always full at the time of the probability change. Therefore, even with such control, the base is maintained at a high value at the time of the probability change.
In addition, the variable winning prize ball device 1 based on the hit by a normal symbol
If the release control of Step 5 is performed simultaneously, Step S1
The opening control of the variable winning ball device 15 based on the hit by the ordinary symbol is performed prior to the process of 64. That is, FIG.
When the 1.6 second release shown in Fig. 6 is being performed,
The process of step S164 is skipped.

As described above, each method different from the method of maintaining the base at the time of the probability change by only the opening control of the variable winning ball device 15 based on the hit by the normal symbol is exemplified, but two or all of these methods are used in common. Is also good. Then, these methods and the opening control of the variable winning ball device 15 based on the hit by the normal symbol may be used in combination.

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.
