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, a judging means for judging a hit or miss with a judgment probability set when a judging ball executes a judging winning condition when a game ball wins a starting winning opening, and a judgment result of, for example, numbers or fruits. A bullet provided with a judgment display means for displaying using a diagram or the like, and a special game execution means for executing a special game advantageous to the player by opening a special winning opening, for example, due to the judgment being a hit. There is a ball game machine.

[0003] The probability of hit determination in this type of ball game machine is published and can be known by the player. There are, for example, three types of setting of the determination probability (settings 1, 2, and 3), and some of them are set at the game store. In this case, the determination probabilities of the settings 1 to 3 are disclosed. .

[0004]

However, only the judgment probability can be known by the player. Expectation calculation based on the judgment probability, for example, if the judgment probability is 1/250, 250 judgments are performed. It is possible to calculate only one hit if it is possible, but the actual results of each ball game machine actually installed in the amusement store (for example, the appearance of hits more than the calculated value based on the judgment probability) Many or few).

An object of the present invention is to display the degree of appearance of a hit in an individual ball game machine by comparing it with an expected value based on a judgment probability, and to assist the player in selecting a stand.

[0006]

According to a first aspect of the present invention, there is provided a method for calculating a jackpot achievement rate for a ball game machine, the method comprising the steps of: Determining means for determining whether or not there is a hit;
A method for calculating a jackpot achievement rate for a ball game machine, comprising: a judgment display means for displaying the judgment result; and a special game execution means for executing a special game advantageous to the player due to the judgment being a hit. It counts the number of hits displayed by the determination display means in a measurement period and the total number of displays by the determination display means in the measurement period, and calculates the number of hits display by the total number of display times and the determination probability. It is characterized in that an expected achievement rate corresponding to a ratio divided by the expected number of hits corresponding to the product is calculated.

The measurement period is, for example, from the opening of the game store to the present, from the present to two hours, from a certain Monday to the present, and the like, but is not limited thereto. The expected achievement rate is equivalent to a ratio obtained by dividing the number of hits displayed in the measurement period by the number of expected hits. For example, assuming that the determination probability is 1/250, the total display count is 1250 times from the opening of the game store to the present as a measurement period, and the hit display count is 5 times, the expected hit count is 1250 × 1/25.
0 = 5, and the expected achievement rate is 5/5 = 1 (100%).
If the number of hits is three with the same determination probability and the same total number of displays, the expected achievement rate is 0.6 (60%).

If the expected achievement rate is displayed as a decimal, percentage, fraction, or the like, for example, the ratio of the number of hits expected from the judgment probability to the number of hits actually appearing is displayed. As a result, this table is likely to hit as expected, this table is unlikely to hit, because it hits (or does not hit), it will be difficult to hit (or easier to hit) soon It is possible to judge or anticipate, etc., and to assist in selecting a platform.

The calculation of the expected achievement rate by this method can be performed by, for example, a hall computer, or can be performed by each of the ball game machines. In the case of using a ball-and-ball game machine, the configuration described in claim 2 may be adopted.
The ball game machine according to claim 2, a determination means for determining a hit or miss with a determination probability set when the determination execution condition is satisfied, a determination display means for displaying the determination result, And a special game execution means for executing a special game advantageous to the player due to the presence of the ball, wherein the number of hits displayed by the judgment display means within a measurement period is determined by the determination within the measurement period. Achievement rate calculation means for calculating an expected achievement rate corresponding to a ratio divided by an expected number of hits corresponding to a product of the total number of display times and the determination probability by the display means, and an achievement rate display means for displaying the expected achievement rate Is provided.

[0010] The measurement period is, for example, from the opening of the game store to the present, from the present to 2 hours, from a certain Monday to the present, and the like, but is not limited thereto. The achievement rate calculating means calculates an expected achievement rate corresponding to a ratio obtained by dividing the number of hits displayed in the measurement period by the number of expected hits. For example, the determination probability is 1/250, and the total number of display times is 1250 with the measurement period from the opening of the game store to the present.
If the number of times of display is 5 times, the number of expected hits is 1250 × 1/250 = 5, and the expected achievement rate is 5/5.
= 1 (100%). Also, if the number of hits is three with the same judgment probability and the same total number of displays, the expected achievement rate is 0.
6 (60%).

The achievement rate display means displays the expected achievement rate. The display of the expected achievement rate may be displayed, for example, as a decimal number, a percentage, a fraction, or the like. In this way, since the ratio between the number of hits expected from the judgment probability and the number of hits actually appearing is displayed, as a player, this table is likely to hit as expected, this table is not likely to hit much It is possible to judge or predict that it is difficult (or easy to hit) to hit because it is just hitting (or not hitting), which can help to select a stand.

If the probability display means is provided as described in claim 3, and the judgment probability is displayed together with the expected achievement rate,
Information for selecting a vehicle will be enhanced.

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 to 24 serving as a work area of CPU 32
The microcomputer is configured as a microcomputer including a counter 38 for repeatedly counting 9, a counter 40 for repeatedly counting 0 to 999, a counter 42 for repeatedly counting 0 to 9 and an input / output port (not shown). Although illustration is omitted, a rotation speed counter and a hit frequency counter are provided on the RAM 36, and C
The PU 32 can update the values of both counters.

The control device 30 is connected to a start winning port 16 and a grand prize device 18, and a start signal output when a sensor incorporated in the start winning port 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. Control circuit 4
4 can display various images on the liquid crystal display panel 20 using the image data. For example, as shown in FIG. 6, a one-digit number is displayed in each of the symbol sections 21a, 21b, and 21c, a character “probability” and a fraction are displayed in the probability section 22, and a character “actual” is displayed in the result section 24. And 1-3
Digit numbers and the "%" symbol can be displayed.
As will be described in detail later, the symbol sections 21a, 21b,
The number to be displayed in 21 c, the fraction to be displayed in probability section 22, and the number to be displayed in result section 24 are instructed by control device 30.

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. The CPU 3 of the control device 30
2 transmits the determination probability (1/250 in this specific example) to the symbol display device 14 to display it in the probability section 22 and instructs the symbol display device 14 as part of the initial setting accompanying the activation of the pachinko machine 10. 0% is displayed in the result section 24, and the rotation number counter and the hit number counter are reset.

As shown in FIG. 3, the CPU of the control device 30
In the determination process, the control unit 32 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 reads the count value (random number 1) of the counter 38, and determines whether or not a hit has occurred based on whether or not it matches the hit value (3 in this specific example) ( S102). As mentioned above, random number 1 is 0
Since there are one hit value in 250 types of 249, the hit probability, that is, the judgment probability is 1/250.

If the determination is successful (S103: YES), the CPU 32 reads the count value (random number 3) of the counter 42 and counts the number of the three random numbers 3 (for example, 777 if the random number 3 is 7). Determined as a display symbol (S
104), if the determination is wrong (S103: NO), the count value (random number 2) of the counter 40 is read, and this random number 2 is determined as a display symbol (S105). Note that CP
In S105, if the random number 2 is one digit (0 to 9), U32 adds 0 as the tens and hundreds digits, and 000,
001, 002, and the random number 2 is two digits (10
~ 99), add 0 as the hundredth digit and 010,
Use three digits such as 011 and 012. When the three-digit number determined based on the random number 2 is equal to three digits such as 000, 111, and 222, one digit is added to one of the numbers (for example, the number of the first digit) and three digits are added. Modify so that they do not line up.

After the processing of S104 or S105, the CPU 32 notifies the symbol display device 14 of the display symbols determined in these processings, and instructs display (S106). Next, the CPU 32 determines whether or not the determination in S102 is a hit, that is, whether or not a hit symbol is displayed on the symbol display device 14 or a non-hit symbol is displayed (S107). If the hit (S107: YES), the special game flag F Is set to 1 (S108), and the rotation number counter and the hit number counter are each incremented by 1 (S10).
9) If not (S107: NO), only the rotation speed counter is incremented by 1 (S110), and the expected achievement rate S is calculated (S111).

The expected achievement rate S is obtained by assuming that the value of the revolution counter is R and the value of the hit counter is V.

[0022]

S = V ÷ (Rx1 / 250) × 100 In addition, 1/250 is a determination probability. Then, the CPU 32 transmits the expected achievement rate S calculated here to the symbol display device 14, instructs updating of the display (S112), and ends the present process.

As shown in FIG. 4, the control circuit 44 of the symbol display device 14 receives a notification of a display symbol (S301: Y).
ES), three symbol sections 21a, 21 of the liquid crystal display panel 20
b and 21c are displayed with a one-digit number variably (S30
From 2), for example, the left symbol section 21a (corresponding to the hundreds digit), the right symbol section 21c (corresponding to the one's digit), and the central symbol section 21b (corresponding to the tens digit) in this order from the control device 30. The number of each digit of the notified display symbol is statically displayed (S303, see FIG. 6). The player can know the result of the determination (hit or miss) by the display on the symbol display device 14.

Further, the control circuit 44 is instructed by the control device 30 to update the display of the expected achievement rate S (S304:
(YES), the numerical value of the result section 24 of the liquid crystal display panel 20 is updated and displayed to the expected achievement rate S sent this time (S30).
5, see FIG. 6). As shown in FIG.
In the special game process, the PU 32 first determines whether or not the special game flag F is set (S20).
1). If the special game flag F is set (S201: YES), the CPU 32 executes processing relating to the special game after confirming that the display of the symbol sections 21a to 21c on the symbol display device 14 has been confirmed (S201). S20
2). The special game is the same as that of the known pachinko machine, but 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. If any of the open prize balls has passed through the special area in the special winning device 18, the special winning device 18 is opened again, and 30 seconds have elapsed or 1
If the ball passes through the special area, it will be closed again when the 0 ball is won, and will be reopened.

The number of times the large winning device 18 is 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), and this process ends.

As described above, since the expected achievement rate S and the judgment probability are displayed, the player can select a platform with reference to these displays. In this specific example,
