Abstract

PROBLEM TO BE SOLVED: To provide a more interesting game by enhancing a player's expectation when a predetermined game value can be imparted if the display result of identification information shows a predetermined specific display condition. SOLUTION: When a value at low probability is, e.g. 3, a jackpot is determined to be won, whereas in the case of other values, the jackpot is determined to be lost. When a value at high probability is either 3, 7, 79, 103, or 107, the jackpot is determined to be won whereas in the case of other values, the jackpot is determined to be lost. When the value of a probability changing counter is 1, the jackpot is determined to be won if the value of a jackpot-determining random number is 3 or 103. When the value of the probability changing counter is 2, the jackpot is determined to be won if the extracted value of the jackpot- determining random counter is 3, 103, or 107. When the value of the probability changing counter is 3, the jackpot is determined to be won if the extracted value of the jackpot-determining random number is 3, 79, 103, or 107.

Behind the glass door frame 2,
The game board 6 is detachably attached. A game area 7 is provided on the front of the game board 6.

In the vicinity of the center of the game area 7, an image display section 9 for variably displaying a plurality of types of symbols and a 7-segment L are provided.
A variable display device 8 including a variable display 10 using an ED is provided. In the image display section 9, "left", "middle",
There are three "right" symbol display areas, and these symbol display areas constitute each variable display section. On the side of the variable display device 8, a passing gate 11 for guiding a hit ball is provided. The hit ball that has passed through the passing gate 11 is guided to the starting winning opening 14 via the ball exit 13. In a passage between the passage gate 11 and the ball outlet 13, there is a gate sensor 12 that detects a hit ball that has passed through the passage gate 11. In addition, the winning ball entering the starting winning opening 14 is guided to the back of the game board 6,
It is detected by the starting port sensor 17. In addition, a variable winning ball device 15 that performs opening and closing operations is provided below the starting winning port 14. The variable winning ball device 15 includes the solenoid 1
6 is opened.

An opening / closing plate 20 which is opened by a solenoid 21 in a specific game state (big hit state) is provided below the variable winning ball device 15. In this embodiment, the opening and closing plate 20 serves as a means for opening and closing the special winning opening. A winning ball that has entered one (V zone) of the winning balls guided from the opening / closing plate 20 to the back of the game board 6 is detected by the V count sensor 22. The winning ball from the opening / closing plate 20 is detected by the count sensor 23. At the bottom of the variable display device 8, the number of winning balls entering the starting winning opening 14 is displayed.
A start winning storage display 18 having a plurality of display units is provided. In this example, the start winning prize storage display 18 increases the number of lit display units by one each time there is a starting prize, with the upper limit being four. Then, every time the variable display of the image display unit 9 is started, the number of the lit display units is reduced by one.

The game board 6 is provided with a plurality of winning ports 19 and 24. Decorative lamps 25 are provided around the left and right sides of the game area 7 so as to blink during the game.
There is an out port 26 for absorbing a hit ball that does not win. In addition, two speakers 27 that emit sound effects are provided at upper left and right sides outside the game area 7. On the outer periphery of the game area 7, a game effect lamp / LED 28 is provided. In this example, a prize ball lamp 51 that is turned on when a prize ball is paid out is provided in the vicinity of one of the speakers 27, and a ball out lamp 52 that is turned on when a replenishment ball is out in the vicinity of the other speaker 27.

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 game is released until one of the following conditions is satisfied: a lapse of a predetermined time and a winning of a predetermined number (for example, 10) of hit balls. 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, 15 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.

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 in accordance with the 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. 3 is an explanatory view showing 15 types of symbols 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 “0” as shown in FIG.
The symbol indicated by the name “n” is sequentially displayed from the symbol indicated by the symbol, and the symbol indicated by the name “0” is displayed after 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. 4 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, processing 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. In this embodiment, as shown in FIG. 5, 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) In order to enhance the 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 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 a process 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, 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. In addition, what is added here is, as shown in FIG.
Of the random numbers of (5), random numbers for determining the outlier symbols of (2),
The random number for reach determination in (4) and the random number for reach operation determination in (5). 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 for 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. 6 shows a process for determining that the hit ball has won the start winning opening 14, and FIG. 7 shows a process for determining a variable display stop symbol on the image display device 9. FIG. 8 is a flowchart showing a big hit determination process.

When a 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. 7 when the variable display of the image display section 9 can be started. 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 takes a value in the range of 0 to 249. Then, as shown in FIG. 8, when the probability is low, for example, when the value is 3, it is determined to be a big hit, and when it is any other value, it is determined to be a deviation. At high probability, for example, the value is 3, 7, 7
If it is any of 9, 103 and 107, it is determined to be a big hit, and if it is any other value, it is determined to be a deviation. Also, when the probability changing flag described later is set, the value of the extracted random number for jackpot determination is 3, 7,
If it is 103, it is determined to be a big hit, and if it is any other value, it is determined to be a deviation. In this embodiment, when the probability changing flag is set, the jackpot determination value is changed (from one type to three types), but when the probability changing flag is set, the big hit determination random number is changed. The update range of the counter (random 1) for generating is different from 0 to 249 (for example, 0 to 249).
99) The jackpot occurrence probability may be changed. In that case, the probability of the change can be more finely controlled.

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 variable design is shown in FIG.
As shown in the table, "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 53 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). Step S75).
Incidentally, the storage area is the RAM 55 in the basic circuit 53.
Is provided.

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. 5 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). 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 the 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). And
It is confirmed whether or not the probability changing flag is set (step S81). When the probability changing flag is not set, it is confirmed whether or not the reach symbol is a specific symbol (step S82). In this embodiment, the specific symbol is the symbol shown in FIG. In FIG. 10, the middle symbol is an arbitrary symbol that does not match the left and right symbols. 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).

When a specific reach occurs by the above-described processing, the probability of a big hit is increased.
In this embodiment, it is increased to three times the normal time (low probability).

Note that the probability changing flag is reset, for example, after a predetermined time has elapsed, after a predetermined number of changes, when a predetermined stop symbol occurs, or when a next reach occurs. In the case of resetting after the elapse of a predetermined time, the timer may be started when the probability changing flag is set, and the probability changing flag may be reset when the time is up. In the case of resetting after the predetermined number of changes, the symbol change number may be counted when the probability changing flag is set, and the probability changing flag may be reset when the count value reaches the predetermined value. In the case of resetting when a predetermined stop symbol is generated, it is only necessary to determine whether or not the stop symbol matches the predetermined symbol when the stop symbol is determined when the probability changing flag is set. Then, in the case of resetting when reach occurs, when the probability changing flag is set, lottery (step S53,
The probability changing flag may be reset when it is determined to reach in the result of S59) or when the left and right symbols are stopped in the image display unit 9 to be in the reach state.

In the above-described embodiment, the jackpot occurrence probability is changed when a specific reach occurs, but may be changed each time a start prize is won. FIG. 11 is a flowchart showing the processing of such an embodiment. In this case, if there is an effective winning in the starting winning opening 14 (steps S41, S4).
2) In addition to incrementing the number of stored start winnings by 1, and increasing the value of the probability change counter by 1 (step S43). When the value of the probability change counter becomes 4, it is returned to 0. Then, the process of step S44 is performed.

FIG. 12 is a flowchart showing the process of determining a big hit in this embodiment. In this case, 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 a deviation. Here, the low probability time is when the probability change is not in progress and the value of the probability change counter is 0. At the time of the high probability, for example, if the value is any one of 3, 7, 79, 103, and 107, it is determined to be a big hit, and if the value is any other value, it is determined to be a deviation. When the value of the probability change counter is 1, the value of the extracted random number for jackpot determination is 3,103.
, It is determined to be a big hit, and otherwise, it is determined to be a deviation. If the value of the probability change counter is 2
In the case of, when the value of the extracted random number for jackpot determination is 3, 103, 107, it is determined to be a jackpot, and when it is any other value, it is determined to be a deviation. When the value of the probability change counter is 3, the jackpot is determined to be a big hit when the value of the extracted random number for jackpot determination is 3,79,103,107. Is determined. In this case as well, the update range of the counter (random 1) for generating the random number for large hit determination according to the value of the probability change counter may be changed from 0 to 249 to change the large hit occurrence probability. . In that case, the probability of the change can be more finely controlled.

According to the above processing, the big hit occurrence probability changes every time there is a start winning prize. In this embodiment, the jackpot occurrence probability increases as the value of the probability change counter increases, so that the jackpot occurrence probability is gradually increased each time there is a start winning.

In the above embodiment, the jackpot occurrence probability is gradually increased when there is a start winning, but the jackpot occurrence probability may be changed when the previous lost symbol is a specific symbol. . FIG. 13 is a flowchart showing the processing of such an embodiment. In this case,
After the processes of steps S41 to S44 are performed, the previous lost symbol displayed on the image display unit 9 is checked.

In this example, the last lost symbol is "three",
If the combination is "*" and "three", the probability change counter is set to 1 (steps S91 and S92). Further, when the previous lost symbol is a combination of "seven", "*", and "seven", 2 is set to the probability change counter (steps S93, S94). Then, when the previous outlying symbol is a combination of "n", "*", and "n", the probability change counter is set to 3 (step S95,
S96). Here, “*” indicates that the middle symbol is an arbitrary symbol that does not match the left and right symbols. In addition, the middle symbol in the previous outlier symbol is "three", "seven" or "n"
Is set to 0 in the probability change counter (steps S95 and S96).

Also in this embodiment, the determination as to whether or not to make a big hit is performed by the processing shown in FIG. Therefore, here, when there is a valid start winning prize and the previous lost symbol is a specific symbol, a big hit occurs at a probability according to the symbol. In addition, when the previous lost symbol is another specific symbol, the big hit occurrence probability is returned to the normal probability. The return to the normal probability may be performed after a lapse of a predetermined time, after a predetermined number of changes, or when the next reach occurs.

In each of the above embodiments, the occurrence of the specific reach and the start winning are set as conditions for changing the jackpot occurrence probability. However, the jackpot occurrence probability may be changed according to the progress period of the game. FIG. 14 is a flowchart showing an example of processing for changing the jackpot occurrence probability according to the progress period of the game.

The circuit on the launch control board 91 supplies a driving signal (such as a launch permission signal) to the hit ball launching device 34.
When the signal is introduced into the main board 31, the basic circuit 53
Can detect the launch of each hit ball. Alternatively, even if a sensor for detecting a hit ball is provided on the game board and information from the sensor is introduced into the main board 31, the basic circuit 53 can detect the firing of each hit ball.

It suffices if the launch of each hit ball can be detected by some method. In the example shown in FIG. 14, the basic circuit 53 detects the hit ball hit into the game area by the ON of the launch permission signal (step). S101). When the hit ball hit in the game area is detected, the value of the hit ball counter is increased by 1 (step S102). When the value of the hit ball counter reaches a predetermined value (300 in this example) (step S103), the value of the probability change counter is increased by 1 (step S104), and the value of the hit ball counter is returned to 0 (step S105). ). When the value of the probability change counter becomes 4, it is returned to 0.

Also in this embodiment, the determination as to whether or not to make a big hit is performed by the processing shown in FIG. Therefore, here, the big hit occurrence probability changes every time the number of hit balls hit into the game area reaches a predetermined number.

In the above example, the jackpot occurrence probability is changed according to the number of hit balls hit into the game area. However, the jackpot occurrence probability may be changed according to the operating time of the gaming machine.
FIG. 15 is a flowchart showing such an example.
In this case, every time the probability change process is started, the timer value is increased by 1 (step S110). Note that the probability change process is added, for example, to the main process shown in FIG. 4 and is executed as a part of the main process, and thus is started every 2 ms. When the timer value reaches a predetermined value (a value corresponding to 180 seconds in this example) (step S111), the value of the probability change counter is increased by 1 (step S112).
The timer value is returned to 0 (step S113). When the value of the probability change counter becomes 4, it is returned to 0.

Also in this embodiment, the determination as to whether or not to make a big hit is performed by the processing shown in FIG. Therefore, here, the jackpot occurrence probability changes according to the operating time of the gaming machine. In order to prevent the probability change process from being executed when the gaming machine is not used, for example, a signal for driving the hit ball firing device 34 is introduced from a circuit on the firing control board 91, and in a state where the signal is not output. Do not execute probability change processing.

In each of the above-described embodiments, the jackpot occurrence probability is changed on the condition of a start winning prize or by internal processing. However, a hit ball passes through a specific passing opening or a hitting ball hits a specific winning opening. The jackpot occurrence probability may be changed on condition that a prize is won.

For example, FIG. 16 shows an example of a specific winning opening 44 provided in the game area. A movable member 43 which opens and closes is provided above the winning opening 44, and a lower side of the winning opening 44. Is provided with a movable member 45 that moves up and down. The movable member 43 is opened for a certain period of time when the basic circuit 53 detects the passage of a hit ball of a specific passage gate 46 via a sensor and gives a drive command to the movable member 43, for example. The movable member 45 repeats, for example, up and down movement. Then, when the movable member 43 is in the open state, the hit ball can enter the area where the winning opening exists, but the movable member 43
Only when the ball 5 is located on the lower side, the hit ball can enter the winning opening 44.

As shown in the flowchart of FIG. 17, when the hit ball wins the winning opening 44 (step S120), the value of the probability change counter is increased by 1 (step S1).
21), start a timer (step S122). In this embodiment, when the value of the probability change counter becomes 3, the value is not increased any more. Then, if the timer is operating (step S123), it is checked whether the time is up (step S124). If the time is up, the value of the probability change counter is returned to 0 (step S125).

In this embodiment, when there is a prize in the winning opening 44, the timer is started, and if there is a prize again before the time is up, the value of the probability change counter increases to a maximum of three. This state continues until the timer times out. Also in this embodiment, the determination as to whether or not to make a big hit is performed by the processing shown in FIG.
Therefore, if the movable member 43 is in the open state and a large number of hit balls can be won in the winning opening 44, the probability of occurrence of a big hit becomes higher. Therefore, the player also pays attention to the approach of the ball to the movable member 43 and the passage of the ball through the passage gate 46 for opening the movable member 43, and the interest of the game can be further improved. Although a relatively complicated accessory has been illustrated here, the jackpot occurrence probability may be changed simply on condition that a specific passing gate passes a ball or a specific winning opening is won.

In addition, when the predetermined condition is satisfied, the high-probability starting winning port provided separately from the starting winning port 14 is enabled, and when a winning is made in the high-probability starting winning port, the winning is determined to be normal. May apply a different jackpot occurrence probability. For example, FIG. 18 is an explanatory diagram showing a portion of a game board surface provided with a pass gate 46 and a high-probability starting winning port 47 which are one example of a condition that satisfies a predetermined condition.

FIG. 19 is a flow chart showing a process for judging that a hit ball has won the starting winning opening 14 in this embodiment. The processes in steps S41 to S44 are the same as those in the embodiment described above, but here, it is also determined whether or not a hit ball has passed through the gate 46 (step S130). When the hit ball passes through the gate 46, a timer is started (step S131). Gate 4
When the hit ball 6 passes, the high-probability starting winning opening 47 is activated for a predetermined period, and the timer is used to measure the predetermined period.

Therefore, the timer is operating and the timer expires (steps S131 and S13).
3) The winning in the high-probability starting winning opening 47 is determined (step S134). When there is a winning in the high-probability starting winning opening 47, the same processing as in step S44 is performed, the value of the probability change counter is increased by 1, and the value is stored (step S136). When the value of the probability change counter becomes 4, it is returned to 0.

Also in this embodiment, the determination as to whether or not to make a big hit is performed by the processing shown in FIG. However, in the process shown in FIG. 12, the value of the probability change counter does not use the value at that time, but is used in step S
The value stored at 136 is used.

Also in this embodiment, if the high probability start winning opening 47 can be hit with a hit ball after the hit ball has passed through the passing gate 46, the big hit occurrence probability becomes higher.
Therefore, the player also pays attention to the passing gate 46 and the high-probability starting winning opening 47, and the interest of the game can be further improved. Here, as an example of the predetermined condition for validating the high-probability starting winning opening 47, the passing of the hitting ball of the passing gate 46 is exemplified, but other various conditions can be adopted.

As described above, in each of the above embodiments,
Since the probability of occurrence of a big hit changes according to the game state, a more interesting game can be played. That is, FIG.
In the embodiment shown in FIGS. 6 to 19, the interest given to the player by the probability-changing role provided in the game area is improved, and even if there is no such role, the game is played. Since the player can feel the change in the jackpot occurrence probability during the game, the gaming machine according to the present invention becomes a gaming machine that attracts more players.
