Abstract

PROBLEM TO BE SOLVED: To equalize the probability of a big hit in a ready-to-win state between a probability variable pattern and an ordinary pattern in a pachinko game machine. SOLUTION: Even when a final definite pattern is a probability variable bit hit pattern, a part of it becomes an ordinary big hit pattern in the stage of a temporary stop pattern, and the probability variable big hit pattern is less by that portion, which acts in a direction of lowering the probability of the big hit when a ready-to-win pattern is the probability variable pattern. An image control device 643 is therefore set to inhibit ready-to-win action by the kind of one pattern when the definite pattern is the probability variable big hit pattern and a probability variable miss pattern with one different pattern. The rate of determining the pattern as the probability variable pattern through the ready-to-win action is thereby reduced to raise the probability of the big hit when the ready-to-win pattern is the definite pattern.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine,
In particular, it relates to reach action and symbol re-lottery determination control.

[0002]

2. Description of the Related Art A ball-and-ball game machine is a game machine that pays out game balls as prize balls when a game ball fired by a player's operation enters a winning opening provided on a game board. Machines are widespread. Pachinko gaming machines are provided with a firing handle below the game board, and when the player turns the handle by a predetermined angle, game balls are continuously fired on the game board surface.

[0003] In recent years, the content of games has changed from a simple game in which a predetermined number of game balls are paid out when the game balls enter a winning opening, to a game in which the game progresses more complicatedly. For example, a display on a game board is provided with a plurality (usually three) of display parts for displaying symbols such as numbers and pictures, and when the game ball enters a predetermined starting port, a large number of display symbols are displayed on the display. Is displayed at a high speed while switching between symbols of different types (for example, 12 types) and stopped after a predetermined time,
At that time, when all the display symbols are aligned, there are some that win this. And on this condition, it is possible to shift to a special game different from the previous game.In the special game, for example, a large winning opening with a wide opening and a large amount of prize balls can be opened, This is advantageous to the player.

There are usually a number of types of jackpot symbols corresponding to the types of symbols that can be displayed in the variable display. For a specific symbol in the jackpot symbol, for example, for half of the jackpot symbol, the special game ends. Later, when the game is returned to the normal game state, the probability of a big hit is increased (probability change (also referred to as probability change)), which is more advantageous to the player. In addition, the time required for the display symbols to start to fluctuate and stop is reduced (time reduction (also referred to as time reduction if appropriate)). State. Probability fluctuation and time reduction usually appear simultaneously.

[0005] In addition, the display is now capable of high-level display using a liquid crystal display, and performs various effect displays to increase the player's expectation and interest. The effect display includes, for example, a display in a reach action mode. This means that the state of the reach symbol in which only one display unit is undetermined and the other display unit stops changing display and is fixed to the same symbol appears, and the symbol of the last one display unit is displayed. Until the decision is made, the player enjoys a sense of happiness that he has greatly approached the jackpot, while providing the player with ample time to enjoy the return of the symbols on the display unit.

Also, at the time of a big hit, the big hit symbol is displayed as a temporary stop symbol, and then the display is changed to another big hit symbol to make it a fixed symbol. Also, a re-lottery in which a part of the promotion is promoted to a jackpot symbol with a profit such as a certain change.

[0007]

By the way, whether or not to execute the reach action and the type of the definite symbol are determined in advance by a ball entry to the starting port as a trigger and before the start of the variable display, together with whether or not a jackpot is determined. The probability of being finally determined from the conventional reach symbol to the first type of jackpot symbol with the benefit of the probability change, etc. is finally determined to the second type of the jackpot symbol without the benefit of the probability change, etc. Is the same.

However, it has been found by the present inventors that the following problem arises by executing the re-lottery. FIG. 7 shows a change pattern from a temporary stop symbol to a confirmed symbol by a re-lottery. Although there are three change patterns, the re-lottery is a function for enhancing interest, and although there is a promotion from the second type of jackpot symbol to the first type of jackpot symbol, the first type of jackpot symbol Will not be demoted to the second type of jackpot symbol. At the time of the temporary stop before the re-lottery, the rate at which the second type of jackpot symbol appears is increased while the rate at which the first type of jackpot symbol appears is reduced as compared with the time of determination.

For this reason, at the stage of the temporary stop, the probability of a big hit in the first type of jackpot symbol through the reach action decreases, and the reach symbol of the symbol corresponding to the first type of big hit symbol is reduced. Sometimes, the expectation of the player is reduced. Also, if the appearance frequency of the first type of jackpot symbol at the temporary stop stage when the confirmed symbol is the first type of jackpot symbol is increased, the second type of jackpot symbol can be changed from the first type of jackpot symbol to the first type of jackpot symbol. The promotion to the jackpot symbol is reduced, and the original interest of the re-lottery is reduced. Thus, there is a possibility that the intended effect of the reach action and the re-lottery cannot be exerted.

The present invention has been made in view of the above circumstances, and has as its object to provide a ball-and-ball game machine in which the effect is not reduced by the type of the reach symbol.

[0011]

According to the first aspect of the present invention, a prize ball is paid out when a game ball fired on the game board enters and a prize hole is paid out. A starting port is provided for changing and displaying each of the plurality of display units while switching among various types of symbols, and if the finally stopped and determined symbol is a big hit symbol,
It is possible to shift to a special game different from the normal game, and when the confirmed symbol is the first type of jackpot symbol, the other second
It is a ball game machine which is designed to give a different game profit from the jackpot symbol of the type, controlling the display,
As the effect display, before the symbol change is stopped and the jackpot symbol or the off symbol is determined, the stage of the reach symbol that has a possibility of a jackpot depending on the symbol of the display portion is not determined yet and some of the display portions are undetermined. In addition to displaying in the reach action mode to give out, at the time of a big hit, after displaying the big hit symbol as a temporary stop symbol, change the display to another big hit symbol and make it a fixed symbol, and some of the second type of big hit symbols A symbol display control means for displaying in a re-lottery mode enabling promotion to a first type of jackpot symbol, and a fixed symbol determination for randomly determining a fixed symbol in advance before a fluctuating display when a game ball enters the starting port. In the ball game machine having means, the probability that the reach action mode is selected is determined by determining that the determined symbol is a part of the first type of jackpot symbol. Reach action for adjusting so that the case of the first type of out-of-the-box design that differs only from the second type of the out-of-the-box design that is only partially different from the second type of the out-of-the-box design Probability adjusting means is provided.

When the symbol change stops after the reach action and the big hit symbol is displayed, the big hit symbol at this time is partially changed to the second type at the temporary stop symbol display stage even in the first type of big hit. , The appearance frequency is biased toward the second type of jackpot symbol.

On the other hand, the out-of-position symbols displayed after the symbol change is stopped and displayed after the reach action have their appearance frequency biased by the reach action probability adjusting means toward the second type of out-of-position symbols.

Thus, the probability that the reach symbol corresponding to the first type of jackpot symbol becomes a jackpot through the reach action and the probability that the reach symbol corresponding to the second type of jackpot symbol becomes the jackpot through the reach action are The difference can be suppressed. Depending on the setting, the above difference can be eliminated. In addition, since this is realized by adjusting the probability that the reach action mode is selected, it is not necessary to reduce the case of being promoted from the second type of big hit symbol to the first type of big hit symbol in the re-lottery, and the promotion is not performed. Can be set arbitrarily.

According to a second aspect of the present invention, in the configuration of the first aspect, when a game ball enters the starting port, a reach action command for setting whether or not to execute a reach action mode display is set in advance. A reach action command generating means for generating the reach action probability adjusting means, wherein the reach action is performed by disabling the reach action command with a preset reach action prohibition probability when the confirmed symbol is a first type of out-of-reach symbol. It is constituted by prohibition means.

It is only necessary to partially prohibit the reach action command when the final symbol is the first type of deviating symbol, so that it can be easily implemented without a large control modification to the conventional ball game machine. can do.

According to a third aspect of the present invention, in the configuration according to the second aspect of the present invention, the reach action prohibiting means is provided in the case where the confirmed symbol is a first type of off symbol and the type of the symbol is different. Is determined to be a predetermined symbol, and if a positive determination is made, the reach action command is set to be invalid.

Since the fixed symbols are determined at random, the above-mentioned partial symbol types having different symbol types also appear at random. Therefore, the reach action can be prohibited with a certain probability only by determining whether or not the part is a predetermined symbol. The reach action prohibition probability can be increased or decreased by the number of types of the predetermined symbol.

According to a fourth aspect of the present invention, in the configuration of the second or third aspect of the present invention, when the reach action is prohibited, the symbol display control means is configured to determine and display the first type of out-of-design symbols. In addition, a setting is made to execute a modified symbol display in which a modified symbol in which one of the display portions on which the same symbol is displayed is replaced with another type of symbol among the determined symbols is displayed.

[0020] The deformed symbol is more similar to the jackpot symbol than the jackpot symbol, which is only partially different from the jackpot symbol, and the player is strongly disappointed even if the deformed symbol is displayed. I don't remember. Therefore,
Before displaying the final confirmed symbol, once, such a modified symbol is displayed, and by allowing the player to recognize that the symbol is off, even if the confirmed symbol is only a part of the symbol different from the jackpot symbol, In addition, it is possible to eliminate a sense of incongruity of the player that the reach action is not performed.

According to a fifth aspect of the present invention, in the configuration of the second or third aspect, when the reach action is prohibited, the same symbol is selected from among the first type of off symbol when the reach action is prohibited. Is set so that any one of the display units where is displayed last stops the variable display.

By allowing the player to recognize that the symbol is off at the stage where the undetermined symbol is left on the display section, the reach action can be executed even if the confirmed symbol is only a part of the symbol that is different from the jackpot symbol. It is possible to remove a sense of discomfort of the player for not being performed.

This one-way communication configuration can be configured using an inverter circuit or a latch circuit.

The operation of the present ball game machine will be described. A game ball is fired according to the amount of rotation of the firing handle 141, and if the game ball enters the winning opening 31, 32, 35, a winning is achieved and a predetermined prize ball is paid out. If the aim is to achieve a high number of winning prize balls, usually the first kind starting port 31 is aimed. Then, if there is a ball in the first-type starting port 31 before the special symbol comes to rest, the main controller 61 counts the number of reserves up to a predetermined value (4) according to the number of balls. This data is reflected in the number of lighting of the special image hold storage LED 642.

Main control device 61 as a fixed symbol determining means
Is basically the same as the conventional device, and in a main routine that starts up at a predetermined cycle due to a hard interrupt, when it is determined that there is a ball in the ordinary electric accessory 31, a hit determination process is executed. , The type of the symbol is randomly determined, and the command command including these data is transmitted to the image control device 643. Also, whether or not to reach is determined at random and transmitted to the image control device 643, and the image control device 643 determines whether or not to display in a reach action mode described later. Main controller 61
Is a reach action command generating means for generating a reach action command for determining whether or not to execute a reach action described later. The reach or not is determined by a random number, which will be described later. From this random number, the change time from the start of the variable display of the symbol until the symbol is determined is determined together with the reach or not. In addition, in the case of the reach, the symbols that are out of order are randomly determined from predetermined symbols so as to correspond to the reach. The jackpot symbols are “111”, “222”, “333” and “44”.
4, 555, 666, 777, 888, 99
9 "," AAA "," BBB "," CCC ".

A known means is used for generating a random number for determining whether or not the above is a jackpot or a reach, for example,
A counter capable of counting up to a predetermined maximum value is prepared according to the type of random number, and the random number is obtained by incrementing the count value by one toward the maximum value each time the main routine starts. The rising cycle of the main routine is as short as 2 ms, and the random numbers are extracted at substantially the same appearance rate. In addition, in order to avoid synchronization between random numbers of different types, a counter for generating an initial random number is provided. For example, when a counter corresponding to a fluctuation time reaches a maximum value, the counter always becomes “0” next. Instead, it becomes the number specified by the initial random number, and then increments toward the maximum value.

FIG. 5 is a flowchart showing a control program executed by the CPU of the image control device 643. The control program is executed when the main control device 61 receives the above-mentioned data such as the big hit symbol. First, a random number is extracted (step S1).
10). This random number includes a random number for extracting a temporary stop symbol at the time of re-lottery.

Next, it is determined whether or not it is a big hit (step S120). If the determination is affirmative, it is determined whether or not the confirmed symbol is a probability-change big hit symbol (step S130). First
The jackpot symbol of the type is a jackpot symbol that is given a right to change the probability that the jackpot probability increases after the end of the special game, and the jackpot symbol other than the jackpot symbol is not given the right to change the probability. It is a normal jackpot symbol that is a type of jackpot symbol. In the following description, “111” “333” “555” “777” “99”
9 "and 6" BBB "
22, "444", "666", "888", "AAA", "C"
"CC" is usually a big hit symbol.

If the jackpot symbol is a positive jackpot symbol, a temporary stop symbol for the jackpot symbol is extracted (step S140), and if it is a normal jackpot symbol, a temporary stop symbol for the normal jackpot symbol is extracted (step S150). The temporary stop symbol is extracted from both the six probability variable jackpot symbols and the six normal jackpot symbols if the confirmed symbol is the probability variable jackpot symbol, and is extracted from the six normal jackpot symbols if the confirmed symbol is the normal symbol jackpot symbol. Extracted from

Next, a variation pattern from the start of the symbol variation to the determination on the display units D1 to D3 is extracted (step S160). The change pattern here includes the display of the re-lottery mode. Therefore, at the time of the jackpot, the re-lottery is performed. The variation pattern also includes a display in a reach action mode.

The display unit D1 is based on such a variation pattern.
To D3 (Step S17)
0). At this time, in the symbol variation display, a reach action is executed when the symbol is determined. Three display units D1
表示 D3, the display is determined first with the same symbol. The symbol in this state is a reach symbol that becomes a big hit if the remaining one of the display units D1 to D3 becomes the same symbol. Thereafter, the same symbol as the two aligned symbols is displayed on the remaining one of the display units D1 to D3,
Remind the player that it is a jackpot.

The symbol at this time is a temporary stop symbol. After the temporary stop, the symbol is changed to a final big hit symbol and the symbol is determined. This symbol may be of a different type from the temporary stop symbol, or may be of the same type. If the determined symbol is a probable jackpot symbol, the probability of a probable change after the final round of the special game increases. In addition, in the mode of the re-lottery, for example, it is general that all the display units D1 to D3 change at the same time and stop at the same time.

On the other hand, the main controller 61 shifts to the control corresponding to the special game in synchronization with the timing when the display symbols of the display portions D1 to D3 are determined to be a big hit, and the attacker door 321 is opened and a large number of prizes are won. Bring out the expected state. Then, if there is a game ball passing through the special area of the special winning opening 32, after the attacker door 321 is once closed as described above, the game of the next round with the attacker door 321 being opened after a predetermined interval is performed. The right to do is updated up to a predetermined number. Further, if the confirmed symbol is a probable change big hit symbol, the effect is stored and the control corresponding to the probable change and the time saving is performed in the next big hit determination process.

In step S160, together with steps S200, S240, and S250 to be described later, effect displays such as a display in the reach action mode and a display in the re-lottery mode are performed by controlling the image display unit 641. This is a procedure as symbol display control means.

If a negative decision is made in step S120, that is, if it is off, it is determined whether or not it is a reach (step S180). A pattern is extracted (step S200). Then, a symbol is displayed in such a variation pattern (step S170). In this variation pattern, the symbol is determined without the above-mentioned reach action.

Step S for judging whether or not reach is possible
If the determination in step 180 is affirmative, the process proceeds to step S210 to extract a confirmed symbol. This symbol is a departure symbol corresponding to the reach action, and differs from the jackpot symbol only in one symbol. Hereinafter, when one symbol different from the jackpot symbol is the same symbol as the other two symbols, the one that becomes the probability variable jackpot symbol is called the probability variation symbol which is the first type of symbol, and is different from the jackpot symbol. When one of the symbols is the same as the other two symbols, the one that usually becomes a big hit symbol is a second type of a non-standard symbol, a normal non-standard symbol. For example, the probability change symbol is "73
7 ", and the normal departure symbol is" 212 ".

Next, it is determined whether or not the extracted symbol is a symbol that is not surely changed (step S220). The determination is made based on whether or not the two types of the extracted symbols are the same as the probable jackpot symbol. For example, "737"
If so, “7” is the same as the probability-change jackpot symbol “777”, and is a probability-variation-missing symbol.

If the determination in step S220 is affirmative, it is determined whether or not a symbol different from the big hit symbol is within a predetermined range (step S230).

Step S230 is a procedure as reach action prohibiting means. The predetermined range is, for example, up to two symbols before and after two aligned symbols. Missing design "4
* 4 ”, the predetermined range is (“ 2 ”,“ 3 ”,“ 5 ”).
"6"). In the case of the off symbol "2 * 2", the predetermined range is ("C""1""3""4"). Here, the determination as to whether or not the value falls within the predetermined range is made based on the above “1” to “1”.
The identification information on the control program for the twelve types of "C" can be easily set by serially numbering. If a positive determination is made, a fluctuation pattern including the reach action is extracted (step S
240), display with such a variation pattern is executed (step S170).

On the other hand, if a negative determination is made in step S230, that is, if a symbol different from the big hit symbol is not within the predetermined range, the process proceeds to step S200. Step S
In step 200, since the fluctuation pattern without the reach action is extracted as described above, it is displayed (step S170).
Determines the extracted symbol without performing the reach action. As a result, the reach action is prohibited for a part of the case where the probable deviation design is extracted.

When a negative determination is made in step S220, that is, in the case of a non-normal design, a variation pattern including a reach action is extracted regardless of the type (step S250), and the display with the variation pattern is performed. The process is executed (Step S170).

As described above, according to the present ball game machine, at step S230, the reach action is prohibited for a part of the pattern in the case of the odd variation design. This effect will be described in detail below.

In the main control unit 61, the probability of the determination of "reach" is 1/10, and the jackpot probability is 1/3.
Assume 00. Here, in the main control device 61, both the probability that the jackpot symbol becomes the probability variable jackpot symbol and the probability that the jackpot symbol becomes the regular jackpot symbol are １ ／, and the temporary stop symbol for the probability variable jackpot symbol is extracted (step S14).
In 0), the probability of becoming a probability-variable jackpot symbol and the probability of becoming a normal jackpot symbol are both １ ／. Therefore, the probability that the temporary stop symbol becomes the probability variable jackpot symbol is 1 /
4 and the probability of becoming a normal jackpot symbol is 3/4. In addition, the probability of the appearance of the probability deviation symbol and the probability of the appearance of the normal deviation symbol are respectively そ れ ぞ れ.

Then, if it is assumed that the jackpot determination process is performed 1200 times and all the events are in accordance with the above-mentioned probabilities, if the conventional gaming machine, 1/10 (12
0) is determined as the reach. Since the probability of appearance is the same for the probability-variable jackpot symbol and the normal jackpot symbol, and for the probability-variable off symbol and the normal loss symbol, the probability of the jackpot and the loss are 60 times and the number of normal symbols is 60 times. Meanwhile, 1
Out of 200 jackpot determinations, four jackpots are determined.
The breakdown is twice the probability jackpot symbol and two regular jackpot symbols.

Of the jackpots, with regard to the probability variable jackpot symbol, half of the temporary stop symbols are usually the jackpot symbol, so from the standpoint of the temporary stop, the probability variable jackpot symbol 1
The number of times the regular jackpot symbol is three times, and from the reach symbol, the probability of the jackpot with the probability variable jackpot symbol is 1/60, and the probability of the jackpot with the regular jackpot symbol is 1/20. In other words, the probability variation in the probability variation reach symbol with the possibility of the probability variation jackpot design becomes worse.

On the other hand, in the present ball game machine, by executing step S230 as described above, the main control is executed if the remaining one symbol different from the two consistent symbols which are out of the certain range is not within the predetermined range. Even if the device 61 determines "reach", the reach action is prohibited.
Therefore, when the jackpot determination process is performed 1200 times, even if 59 symbols are determined to be “reach” (= 60−1) for the probability change symbol, the reach action is actually performed among the 59 times. Are executed less frequently. Therefore, since the reach action is not executed for the symbol with the probability variation deviation, the jackpot probability in the probability variation jackpot symbol seen at the stage of the temporary stop is improved.

Here, if the above-mentioned predetermined range is narrow, the case where the reach action is prohibited even if the "reach" is determined for the symbol which is out of the certainty variation increases, so that the remaining one symbol which is different from the two aligned symbols is increased. If the predetermined range is about 1/3 of the 11 types of symbols that can be taken, the jackpot probability of the probability-changing reach can be set to the same level as in the case of the normal reach with the normal reach symbol that can be a normal jackpot symbol it can. According to the present embodiment, as described above,
By setting the predetermined range to a total of four symbols up to two before and after the two aligned symbols, the reach action is prohibited for approximately two-thirds of 38 times out of the 59 times of the above-mentioned 59 times that the symbol is a surely variable design, and the jackpot of the probabilityly variable reach The probability and the jackpot probability of the normal reach can be made comparable.

Thus, regardless of whether the reach is the probability change reach or the normal reach, the player can enjoy the feeling of being close to the jackpot and enjoy the happiness of the symbol on the final display portion whose symbol is undetermined. We can provide a fulfilling time to stir.

Moreover, at the time of the temporary stop, about one-third of the normal jackpot symbol is promoted to the probability variable jackpot symbol, and the promotion frame is sufficient. With this, the player first knows that the temporary stop symbol is a big hit, and when the symbol changes from the temporary stop symbol toward the final symbol determination, the final determined symbol is a probability change jackpot symbol or a normal jackpot symbol. You will have to wait for the final time while feeling thrilling about how it will be. It is possible to provide the player with an interesting game that is likely to be re-drawn.

The predetermined range does not need to be continuous, but may be discrete. For example, the above symbol “5 *
If it is "5", the predetermined range of "*" is (2, 4, 6, 8).

Alternatively, a plurality of predetermined ranges are prepared, and
In step S110, a random number for selecting a predetermined range may be extracted. Depending on the design, it is possible to avoid a situation in which a person who comes off via the reach action and a person who comes off without the reach action are separated.

Further, simply, the predetermined range can be fixed irrespective of the type of two aligned symbols. In this case, the rate at which the reach action is prohibited varies depending on the two aligned symbols, but the control load can be reduced.

In the case of a non-reachable symbol in which the reach action is prohibited in step S230, in step S200 as the procedure of the symbol display control means,
Prior to displaying the fixed symbol, a variation pattern may be set such that one of the two aligned symbols is used as another symbol and a deformed symbol in which three symbols are separated is displayed. For example, when the finalized symbol is “737”, it is stopped once at “735”. As a result, the player first recognizes that the player has missed the game, and even if the finally determined symbol has two symbols, the player does not recognize that the reach action has not been performed. I don't remember nature.

Alternatively, in step S200 as the procedure of the symbol display control means, it is also possible to first determine two irregular symbols and then stop and determine the remaining one variable display. For example, if the confirmed symbol is “737”,
“7” and “3” of the left display unit D1 and the center display unit D2 are determined, and only the right display unit D3 continues random display. After a predetermined interval, “7” is displayed.
To stop it. As a result, the player recognizes that the final symbol is “out of alignment” from the two symbols that are not determined but are not aligned, and the last symbol to be determined is one of the two symbols that have already been determined. Even if it is the same as above, the player does not feel unnatural that the reach action was not performed.

Further, in this specific example, when the confirmed symbol is the probability variable jackpot symbol, the temporary stop symbol is divided with the probability equal to the probability variable jackpot symbol and the normal symbol jackpot symbol. The present invention can also be applied to a ball game machine in which the appearance probability of the jackpot symbol is lower, and the following effects are obtained. In the case of such a ball game machine, even in the conventional configuration, the probability of promotion from the normal jackpot symbol to the probable jackpot symbol increases, and the expectation of the player for the re-lottery itself is increased. However, since the appearance ratio of the probability variable jackpot symbol at the stage of the temporary stop is further lower than the normal symbol, the conventional ball game machine has a lower probability of the jackpot in the probability change reach, and is relatively relatively normal hit. It becomes a very unbalanced thing with a higher jackpot probability. For this reason, the player's expectation for the certainty change reach is further reduced, and the player is almost disappointed.

According to the present invention, if the predetermined range is further reduced than in the above-described specific example, the reach action with the out-of-probability symbol is further prohibited. Standard. It is possible to arbitrarily set the promotion probability from the normal jackpot symbol to the probability jackpot symbol without reducing the sense of expectation for the probability jackpot reach.

A reach action probability adjusting means for adjusting the probability that the reach action mode is selected in the case of a departure is smaller in the case where the definite symbol is in the surely deviated pattern than in the case of the deviated symbol. The reach action prohibition means (step S230) for lowering the probability of the reach action appearing in the probable out-of-design symbol is used. The jackpot probability may be equalized between the probability change reach symbol and the normal reach symbol.

Further, in the above specific example, the re-lottery is always executed at the time of the big hit. However, the present invention can be applied to a ball game machine in which the re-lottery is executed at a predetermined probability. . FIG. 6 shows a flow of a control program in the image control device of such a ball game machine.

In step S111, step S1
Random number extraction is performed in the same manner as in 10. At this time, in addition to the random numbers, a random number for determining whether or not to execute a re-lottery is also extracted.

Subsequently, it is determined whether or not a big hit has occurred (step S120). If the determination is affirmative, it is determined whether or not a re-lottery is to be executed (step S125). If the affirmative determination is made, it is determined whether or not the confirmed symbol is a probable jackpot symbol (step S130). If it is a probable jackpot symbol, a probabilistic temporary stop symbol is extracted (step S141). A temporary stop symbol is extracted (step S1)
50).

If a negative determination is made in step S125, that is, if the re-lottery is not to be executed, a variation pattern of only the reach action that does not execute the re-lottery is extracted (step S161).

On the other hand, if a negative decision is made in step S120, that is, if it is out of range, display mode determination processing is executed (step S300). This is the same as step S18
In the same manner as 0 to S250, the reach action is prohibited when the confirmed symbol is a part of the symbol which is not surely changed.

Here, the temporary stop symbols for the normal jackpot symbols (step S150) are all normally ordinary jackpot symbols in order to exclude the fact that the probability variable jackpot symbols at the time of the temporary stop are demoted to the normal jackpot symbols as described above. , The temporary stop symbol for the probability variable jackpot symbol (step S141) includes the probability variable jackpot symbol and the normal jackpot symbol at a predetermined ratio. Here, let x be the probability that the temporary stop symbol will be the probability variable jackpot symbol when the confirmed symbol is the probability variable jackpot symbol.

Now, in the case of a jackpot, if the probability that the confirmed symbol is a probability variable jackpot symbol and the probability that it is a normal jackpot symbol are each １ ／ and the probability of the re-lottery is p, The probability P1 (probable change) of the jackpot symbol at the time of the end of the reach action and the probability P2 (normal) of the normal jackpot symbol are both the probability of the jackpot symbol being determined through the re-drawing and the re-drawing. Is the sum with the probability of the jackpot symbol being determined, and is given by the following equations (1) and (2). P1 (probable change) = xp (1/2) + (1-p) × (1/2) (1) P2 (normal) = (1-x) p × (1/2) + p × ( (1/2) + (1-p) × (1/2) (2)

The first term xp × (1/2) in equation (1) is the probability that the re-lottery will be performed and both the temporarily stopped symbol and the confirmed symbol will be probable variable jackpot symbols, and the second item (1-p) × (1/2)
Is the probability of being determined to be a probable jackpot symbol without re-drawing. Also, the first term (1-x) p in equation (2)
× (1/2) is the probability that the temporary stop symbol is promoted to a probability change symbol with a normal jackpot symbol, and the second term p × (1/2) is
The probability that the re-lottery will be performed and the temporary stop symbol will usually be a jackpot symbol and will not be promoted, and the third term (1-p) x (1/2) will be
This is the probability of determining a normal jackpot symbol without a re-lottery being performed.

Therefore, in order to equalize the probability of a jackpot in the probability change reach and the probability of a jackpot in the normal reach, the probability of executing the reach action in the case of a non-probable design and the reach action in the case of a non-normal design are determined. The ratio of the execution probability is the probability P1 (probability) and the probability P2
It is sufficient to prohibit the reach action in the case of the symbol that is out of the certainty so as to have a ratio to (normal) (step S300).

Since the nature of the game differs depending on how the above x and p are taken, x, p is considered in consideration of the player's preference and the like.
Is set appropriately, but regardless of how x and p are taken, by prohibiting the reach action in accordance with the ratio of the probability P1 (probable change) and the probability P2 (normal), , And the probability of a jackpot in a normal reach can be equalized.

Also, as in the above specific example, in the 1200 jackpot determination process, a case where the jackpot symbol at the end of the reach action is a jackpot symbol that becomes a probability variable jackpot symbol once and a jackpot symbol that becomes a normal jackpot symbol is three times. , Probability P1 (probable change): probability P2 (normal)
= 1: 3, and the following equation (3) holds. (1-x) p = 1/2 (3)

The solution (x, p) is, for example, (1/2,
1) and (0, 1/2). The former solution is step S1
No. 61 corresponds to the example of FIG. 5 in which the non-execution, that is, the re-lottery is always executed. The latter solution has a simple configuration in which the re-lottery is performed with a probability of 1/2 and all the temporarily stopped symbols are set to the normal jackpot symbols at the time of the re-lottery. In the latter case, the promotion probability is １ ／.

Further, the present invention can be applied to a ball-and-pay game machine in which the different profits in the game depending on the type of the big hit symbol are not only the certainty and the time saving but also other profits.
