Abstract

PROBLEM TO BE SOLVED: To really feel a high probability by pattern display by performing display by a pattern group for standard probability display when judgement is a standard probability and performing the display by the pattern group for high probability display when the judgement is the probability higher than that. SOLUTION: The CPU 32 of a controller 30 judges the probability based on start signals from a start winning port 16. At the time of the high probability, the counted value of a counter 38 is read and compared with a winning numerical value and winning and losing are judged. At the time of the winning, the counted value of the counter 42 is read and a number for which two random numbers are lined is displayed at a pattern display device 14 as a display pattern. At the time of the losing, the lower two digits of the random number based on the counted value of the counter 40 are displayed as the display pattern. At the time of not the high probability, corresponding to a similar procedure, based on the pattern group for the standard probability, the winning and the losing are displayed by three-digit display. In such a manner, the display is changed depending on whether it is the high probability or a low probability and the high probability is really felt.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ball and ball game machine.

[0002]

2. Description of the Related Art Conventionally, when a symbol array (for example, 7, 7, 7, etc.) is displayed on a symbol display device provided on a game board, for example, a large winning opening called an attacker is opened to give a player a game. Advantageous special games (jackpot operation)
There are ball game machines that perform.

When a specific symbol (probability changing symbol) is displayed in this type of ball game machine, the probability of determining a hit, that is, the probability of executing a special game is improved (the determination probability is increased). There is a game that executes special games at relatively short intervals to enhance the interest of the player. The ball-and-ball game machine of this mode is also called a probability fluctuating machine, and the probability improvement period in which this determination probability is set to a high probability is usually continued until a predetermined number of (for example, two to three) special games are started. . During a special game, the determination probability is usually set to a low probability.

[0004] Further, in this probability variation machine, when a probability variation symbol is displayed during the probability improvement period, a ball-ball game machine (for example, a special game machine) that enhances the interest of the player by extending the probability improvement period is provided. JP-A-6-170045).

[0005]

However, in the conventional probability variation machine, even if the judgment probability is made high, the hit probability on the display (the number of symbols per total number of symbols) is low. Was the same as In addition, although there was a thing which displays that it is a high probability by lighting a specific lamp etc., it was not able to realize the high probability only by displaying a symbol.

[0006] An object of the present invention is to provide a ball and ball game machine capable of realizing that a symbol display has a high probability.

[0007]

According to the first aspect of the present invention, there is provided a ball game machine having a high probability of hitting a reference probability or a hit rate higher than the reference probability when a determination execution condition is satisfied. Determining means for determining a hit or miss with a determination probability set to any of the probabilities; display instructing means for instructing display of a hit symbol indicating a hit or an off symbol indicating a miss in accordance with the determination result; A symbol display means for displaying the winning symbol or an off symbol according to the instruction of the means, and setting the determination probability to the high probability if the winning symbol indicated by the display instruction means is a predetermined specific symbol. When the probability return condition is satisfied, the determination probability is returned from the high probability to the reference probability, and if a low probability period is set, the determination probability is limited to the low probability period even before the probability return condition is satisfied. And a probability setting means for setting the determination probability to the reference probability, the display instruction means, when the determination is made at the reference probability, included in a symbol group for reference probability display Instruct the display of the winning symbol or the missing symbol to be displayed, and when the determination is made with the high probability, the ratio of the total number of the winning symbols to the total number of the missing symbols is larger than the symbol group for the reference probability display. The display of the winning symbol or the missing symbol included in the symbol group for displaying a high probability is instructed.

The display instructing means instructs display of a hit symbol or a missing symbol included in the symbol group for displaying the reference probability when the determination is made with the reference probability. Since the ratio of the total number of winning symbols to the total number of symbols deviating from the symbol group for probability display is larger, the display of the winning symbol or the symbol missing in the symbol group for high probability display is instructed, so the high probability is also displayed on the symbol display Can be realized.

In order to further clarify that the probability is high, it is preferable to change the display form of the symbol. Specific examples include the configuration described in claim 2 and the configuration described in claim 3. The ball game machine according to claim 2 is the ball game machine according to claim 1, wherein the winning symbol and the missing symbol included in the symbol group for displaying the reference probability are a combination of a plurality of symbol elements. Or a form that indicates that it is off,
The winning symbol and the off symbol included in the symbol group for the high probability display, the hit or the off with a number of the symbol elements less than the winning symbol and the off symbol included in the symbol group for the reference probability display. It is characterized in that it can be displayed.

For example, a winning symbol and a missing symbol included in a symbol group for displaying a reference probability are determined based on whether or not three-digit numbers and figures are aligned (for example, 333, 7).
As a form of displaying a pattern such as “77” or “out” (for example, 332, 757, etc.), a winning symbol and a missing symbol included in a symbol group for high-probability display are, for example, the same as those in the last two digits of three digits. In the display of a hit (for example,? 33,? 77, etc.,? Is an arbitrary symbol), if it is not aligned, it can be displayed as a miss. At this time, the design element (*) which becomes almighty is always displayed in the upper three digits, and * 33 and * 77 can be displayed as hits, and * 32 and * 57 can be displayed as deviated.

According to a third aspect of the present invention, in the ball game machine according to the second aspect, the winning symbol and the missing symbol included in the symbol group for displaying a high probability are symbols for displaying the reference probability. In the case of a ball game machine characterized by being constituted by a smaller number of the symbol elements than the winning symbol and the off symbol included in the group, for example, the winning symbol included in the symbol group for reference probability display In the same manner as in the upper example, the high-probability display is a form in which a hit (for example, 333, 777, etc.) or a miss (for example, 332, 757, etc.) is displayed depending on whether or not three-digit numbers or figures are aligned. The winning symbol and the missing symbol included in the symbol group are composed of two-digit numbers and figures.
3, 77, etc.), if they are not aligned, it can be regarded as a missed display.

Alternatively, the symbols included in the symbol group for high-probability display may include only one-digit numbers or figures, and the display may be such that specific numbers, for example, 3 and 7, are hit and others are out. Alternatively, at the reference probability, the display is performed using three display sections for three digits, and at the high probability, the display is performed using only two or one of these three display sections. The display location may be changed between when the probability is high.

According to the configuration of the second or third aspect, it is possible to make it clear that the probability is high, and to make the player realize that it is easy to hit (the probability is high). The determination execution conditions include, for example, entering a specific winning opening or a ball entrance, or passing through a specific passage (gate), but the point is that even if a condition that triggers the execution of the determination is set. It is only necessary to be there, and it is not limited to these.

Examples of the probability return condition include a case where the number of hit determinations based on a high probability reaches a predetermined number, a case where a hit symbol other than a specific symbol continues a predetermined number of times, and the like. It is only necessary to set conditions for returning to the reference probability (low probability) from, and the present invention is not limited to these.

The low probability period is exemplified by a case where it is preferable to set a low probability due to the nature of a ball game, such as during execution of a special game, but the setting of the low probability period is not essential.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to embodiments of the present invention.

[0017]

As shown in FIG. 1, a liquid crystal display panel 20, which is a part of a symbol display device 14, is provided at the center of a game board 12 provided in a pachinko machine 10 as a ball game machine of the present invention. It is assembled. A winning opening 16 is provided below the liquid crystal display panel 20, and a large winning device 18 called an attacker is provided below the opening winning opening 16. The big winning device 18 has a structure that is opened when the opening / closing plate 26 is tilted toward the player (toward the player) and closed when raised as shown in FIG.
And a solenoid (not shown) for driving the motor 6. Further, the game board 12 is provided with a windmill, a well-known winning opening, and the like (not shown). Since the overall configuration of the pachinko machine 10 complies with the conventional technology, illustration and description are omitted.

As shown in FIG. 2, the pachinko machine 10 includes a control device 30 for controlling the overall operation of the pachinko machine 10. The control device 30 includes a CPU 32, a CP
A ROM 34 storing a U32 operation program and the like,
RAM 36, 0-29 serving as a work area for CPU 32
9 for repeatedly counting 9;
The microcomputer is configured as a microcomputer including a counter 40 for repeatedly counting 999, a counter 42 for repeatedly counting 0 to 9 and an input / output port (not shown).

The control device 30 is connected with a start winning opening 16 and a big winning device 18. A start signal output when a sensor incorporated in the starting winning opening 16 detects a winning ball, and similarly a start signal. A winning signal output from a sensor in the special winning device 18 is input. The symbol display device 14 is also connected to the control device 30. The symbol display device 14,
In addition to having the above-described liquid crystal display panel 20, a CPU, a RAM,
It has a built-in control circuit 44 configured as a microcomputer having a ROM, input / output ports, and the like. The ROM of the control circuit 44 stores, in addition to the program of the CPU, numeral design data in which ten types of numerals from 0 to 9 are designed and other image data.

Next, the operation of the control device 30 and the symbol display device 14 relating to the symbol display in the pachinko machine 10 will be described according to the determination process and the special game process that the CPU 32 of the control device 30 repeatedly executes at a preset timing. I do. As shown in FIG.
In the determination process, the CPU 32 of 0 first determines whether or not a start signal has been input from the start winning port 16 (step 101; hereinafter, step is abbreviated as S).
If the start signal has been input, the CPU 32 determines whether the setting of the determination probability is a high probability (1/30 in this specific example) or a low probability (1/300 in this specific example) (S102). Note that this determination probability is low by default, and is set in a special game process described later.

If the setting is high probability (S102: YE
S), the CPU 32 reads the count value (random number 1) of the counter 38, and the read value is a hit value (0, 30, 60, 90, 120, 150, 180, 21 in this specific example).
0, 240, and 270) (S10).
3).

Then, if the determination is successful (S104: YES), the CPU 32 reads the count value (random number 3) of the counter 42, and counts the number of the two random numbers 3 (for example, 77 if the random number 3 is 7). Determined as a display symbol (S1
05), if the judgment is not correct (S104: NO), the count value (random number 2) of the counter 40 is read and the random number 2 is read.
Are determined as the display symbols (for example, 94 if the random number 2 is 294) (S106). Note that the CPU 32
At 106, if the random number 2 is one digit (0 to 9), 0 is added as a tens digit to make two digits such as 00, 01, and 02. The two-digit number determined based on the random number 2 is 00, 1
In the case where two digits are aligned as in 1 and 22, correction is made so that one digit (for example, the number of ones digit) is added to one digit and two digits are not aligned.

On the other hand, if the setting is not high probability (S10
2: NO), the CPU 32 similarly reads the random number 1 and
It is determined whether or not it is a hit based on whether or not it matches the hit value (0 in this specific example) (S107). If the determination is successful (S108: YE)
S), the count value (random number 3) of the counter 42 is read, and a number in which the three random numbers 3 are arranged (for example, 777 if the random number 3 is 7) is determined as a display symbol (S109). : NO), the count value (random number 2) of the counter 40 is read, and the random number 2 is determined as a display symbol (S110). Note that the CPU 32 determines in S11
In the case of 0, if the random number 2 is one digit (0-9), 00 is added to the hundreds and tens places to add three digits, and the three-digit number determined based on the random number 2 is 000, 111, 222. As described above, when the three digits are aligned, one additional number (for example, the number of ones digit) is added to the number so that the three digits are not aligned.

The CPU 32 determines in steps S105, S106, S1
After the processing of 09 or S110, the display symbol determined by either of them is notified to the symbol display device 14 to instruct display (S111). In the symbol display device 14, if the notified display symbol is three digits,
As shown in (a), a display frame 24 composed of three squares 22 is displayed on the liquid crystal display panel 20, and then the numbers 0 to 9 are randomly displayed in each square 22, and then left. The digits of each digit of the display symbol notified in the order of the square 22, the right square 22, and the central square 22 are displayed in a static manner. If the notified display symbol is two digits, the control circuit 44 causes the liquid crystal display panel 20 to display a display frame 24a including two squares 22a as shown in FIG. After the numbers 0 to 9 are randomly displayed, the numbers of the digits of the display symbols notified in the order of the left cell 22a and the right cell 22a are statically displayed.
The player can know the result of the determination (hit or miss) by the display on the symbol display device 14.

Referring back to FIG. 3, the CPU 32 next proceeds to S103.
Alternatively, it is determined whether or not the determination in S107 is a hit, that is, whether or not a hit symbol is displayed on the symbol display device 14 or an off symbol is displayed (S112).
If 2: (NO), the determination processing is terminated as it is, and the hit (S
If 112: YES), the special game flag F is set to 1 (S113), and the determination processing ends.

As shown in FIG. 4, in the special game processing, if the special game flag F is set (S201: YES), the CPU 32 confirms that the display of the determination result on the symbol display device 14 is determined. Then, a process related to the special game is executed (S202). Special games are
Although it is the same as that of a known pachinko machine, it will be briefly described below. The CPU 32 first opens the special winning device 18, and closes the special winning device 18 when the open state has elapsed for 30 seconds or when the winning during opening has reached 10 balls.
Then, one of the open prize balls is the grand prize device 1
The special winning device 18 is opened again when the vehicle passes through the special area in the area 8, and closed after the elapse of 30 seconds or when 10 balls are won.

The number of times the large winning device 18 has been opened is 16
If the number of times has reached or if no winning ball has passed through the special area while the special winning device 18 is being opened, the CPU 32 determines that the special game has ended (S203: YES), and the special winning device 18
Is not reopened, the special game is terminated and the special game flag F
Is reset (S204).

When the special game is over, the CPU 32 returns to S
Whether the random number 3 used in determining the display symbol in 105 or S109 is a probability change numerical value (3 in this specific example)
Or 7) is determined (S205). If it is the probability change numerical value (S205: YES), the CPU
32 sets the determination probability to a high probability (S206). As a result, the hit or miss is determined with a high probability from the next time until returning to the low probability setting.

If it is not the probability change numerical value (S20)
5: NO), the CPU 32 determines whether or not the determination probability up to that time is high and the condition for returning the probability to low probability is satisfied (S207). In this specific example, as a condition for returning from the high probability to the low probability, the use of the random number 3 other than the probability change numerical value in S105 continues twice (that is, in the win display, a value other than 33 or 77 continues twice). That is set.

If the determination in S207 is affirmative (the condition for returning to the high probability and returning to the low probability is satisfied), the CPU 32 proceeds to S20.
Then, the process proceeds to step 8 to set the judgment probability to the low probability, and then terminates this processing. If the determination is negative (high probability, but the condition to return is not satisfied, or the probability is low), the processing is terminated.

As described above, if the judgment probability used in the judgment processing is high, the symbol display device 14
The hit or miss is displayed by two digits display by two squares 22a,
If the judgment probability is low, the hit / miss is displayed by the three-digit display of the three squares 22, so that the player can display the two-digit display or the three-digit display.
It is possible to know whether the probability is high or low depending on whether the display is in digits.
In addition, when the probability is high, the probability on the display is 1/10, so that it is possible to realize that the situation is easy to hit.

Although the embodiments of the present invention have been described with reference to the specific examples, the present invention is not limited to such specific examples, and various modifications can be made without departing from the gist of the present invention. Needless to say. For example, when the probability is low, three digits may be displayed as shown in FIG. 5A, and when the probability is high, one digit may be displayed only for the square 22b as shown in FIG. 5C. When the probability is high, the almighty (*) is always displayed on one of the squares 22 as shown in FIG. 6 (a), or one of the squares 22 is blanked as shown in FIG. 6 (b). Practically 2
It is also possible to display a single digit, or to make the two squares 22 always almighty or blank, so as to substantially display a single digit. The specific examples and some examples described above are merely examples, and other display forms may be used.
