DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine, and more particularly, to a game machine having a design variation display means. The present invention relates to a ball game machine in which the probability of appearance of a stop mode is improved.

[0002]

2. Description of the Related Art Conventionally, as this kind of ball-and-ball game machine, a symbol variation display means having a plurality of symbol display columns for varyingly displaying a plurality of types of symbols and sequentially stopping the variation display, A stop symbol determining means for determining a stop symbol to be stopped and displayed on the variable display means, and in the stop symbol determined by the stop symbol determining means, a stop symbol of a symbol other than the symbol display column to be stopped last. If the combination matches the combination of the symbols constituting the special prize mode, the symbol variation mode is changed after changing the symbol stop mode in the symbol display row to be stopped last to a reach variation speed lower than the normal variation. A special reach stop state of stopping the symbol fluctuation after changing the special reach fluctuation display speed lower than the reach fluctuation display speed Whether to have been determined by lottery.

[0003]

However, in the above-described conventional ball game machine, the combination of symbols stopped in the symbol rows other than the symbol display row to be stopped last is a combination of symbols constituting a special prize mode. The stop mode of the symbol when it matches the combination is determined by lottery, so even if the game is continued for a long time and the symbol variation display means repeatedly displays the symbol variation many times, the reach stop mode appears. There was no case.

[0004] A ball game machine having a symbol variation display means is provided with a ball game machine having a symbol variation display means, in addition to enjoying that a game ball fired on the board flows down while changing its direction in various ways while hitting a nail. It is common to play a game while checking various effects due to the symbol variation by the symbol variation display means, for example, the stop state of the symbol. In particular, for the symbol display column to be stopped last, the special reach stop mode of stopping after changing the special reach variation display speed lower than the reach variation display speed is significantly different from the normal stop mode performed in a normal state. Finally, in the symbol display column in which the fluctuation of the symbols is stopped, the fluctuation display is performed at a considerably low speed enough to give an expectation that the fluctuation display will be stopped at any time. It is a big factor that gives great pleasure to the game in the machine.

[0005] For this reason, it is unlucky to continue the game by the ball and ball game machine for a long time and repeat the symbol change by the symbol change display means many times, and the combination of the stop symbols stopped and displayed on the symbol change display means is special. If the combination does not match the combination that constitutes the prize mode, and if the special reach stop mode does not appear, there is a problem that the game played by the ball game machine becomes boring.

Therefore, the ball game machine according to the first aspect of the present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the purpose of the present invention. The present invention aims to provide a ball game machine capable of increasing the fun of the game by the ball game machine by increasing the probability of the lottery to perform the special reach mode when the number of times reaches a certain number.

In addition to this, the ball game machine according to the second aspect of the present invention increases the lottery probability of repeatedly performing the special reach mode every time the number of symbol changes by the symbol variation display means reaches a predetermined number. Another object of the present invention is to provide a ball game machine capable of periodically performing a special reach stop mode.

[0008]

SUMMARY OF THE INVENTION The present invention is to achieve the above-mentioned object, and its contents will be described below with reference to embodiments shown in the drawings. The ball game machine according to claim 1, a normal stop mode in which a plurality of symbol display columns are sequentially stopped and displayed at a normal fluctuating speed, and a plurality of symbol display columns are sequentially stopped and displayed at a normal fluctuating speed. Regarding the symbol display columns to be stopped, the reach stop mode of stopping after changing to the reach variation display speed lower than the normal variation speed, a plurality of symbol display columns are sequentially stopped and displayed at the normal variation speed, and finally stopped. For the symbol display column to be changed, a change mode storage means having a special reach stop mode for stopping after changing the special reach change display speed lower than the reach change display speed, and a first mode for selecting the normal stop mode A lottery table (15th step S215), a second lottery table for selecting the reach stop mode (14th step S214),
A third lottery table (a thirteenth step S213) for alternatively selecting one of the reach stop mode and the special reach mode, and selecting one of the reach stop mode and the special reach mode And a fourth lottery table in which the appearance rate of the special reach stop mode is set higher than the reach stop mode (eighth step S20).
8) and the variation method lottery table having a variation counter (e.g. fourth step S204) for counting the number of times of the change in the pattern by the symbol variable display means, the stop symbol determined
(For example, the first step S20
1. Second step S202) To correspond to the stop symbol
To determine whether to select one of the lottery table (e.g. Fifth step S205 · sixth step S20
6) , if the counter value of the fluctuation number counter exceeds a predetermined number, the fourth one of the lottery tables is selected.
Lottery table selecting means (for example, the fifth to seventh step S
205 to S207), random number generating means for sequentially generating a variation method random number under predetermined conditions, and random number extracting means for extracting the variation method random number generated by the random number generating means (ninth step S209) and a variation method determining means for comparing the random number value of 1 extracted by the random number extracting means with the lottery table selected by the lottery table selecting means to determine a corresponding symbol variation display mode (ninth step) S
209) and causing the symbol variation display means to perform the symbol variation display in a variation mode corresponding to the result of the determination by the variation method determining means among the symbol variation display modes stored in the variation mode storage means. And a symbol variation control unit (twelfth step S212) for stopping and displaying the stop symbol determined by the stop symbol determination unit.

Therefore, according to the first aspect of the present invention, the variation counter counts the number of symbol variations by the symbol variation display means (for example, the fourth step S20).
Four). The lottery table selecting means selects a lottery table for determining a variation method from any of the first to fourth lottery tables of the variation method lottery table according to a predetermined condition (for example, fifth step S205, sixth step S20).
6).

The lottery table selecting means, when the counter value of the fluctuation number counter exceeds a predetermined number,
The fourth lottery table is selected in preference to the other lottery tables (for example, a seventh step S207). The random number generation means sequentially generates a random number for variation method lottery under predetermined conditions. The random number extracting means extracts a random number for variation method lottery generated by the random number generating means.

The variation method determining means compares the random number value extracted by the random number extracting means with the lottery table selected by the lottery table selecting means to determine a corresponding symbol variation display mode (ninth aspect). Step S209). For example, when the lottery table selection means selects the first lottery table, the variation method determination means determines the symbol variation display mode to the normal stop mode.

[0012] For example, the lottery table selecting means may select the second
When the lottery table is selected, the variation method determining means determines the symbol variation display mode to the reach stop mode. For example, when the lottery table selecting unit selects the third lottery table, the changing method determining unit determines the symbol change display mode to be either the reach stop mode or the special reach stop mode.

[0013] For example, the lottery table selecting means may be a fourth
When the lottery table is selected, the variation method determining means determines the symbol variation display mode to be either the reach stop mode or the special reach stop mode. Here, in the fourth lottery table, the appearance rate of the special reach stop mode is set higher than that of the reach stop mode. Therefore, when the lottery table selecting means selects the fourth lottery table, the variation method is used. The probability that the lottery means determines the symbol variation display mode to the special reach stop mode increases.

The symbol variation control means causes the symbol variation display means to perform the symbol variation display in the variation mode corresponding to the result of the determination by the variation method determining means among the symbol variation display modes stored in the variation mode. (For example, twelfth step S212). For example, when the variation method determining means determines that the symbol variation mode is the normal stop mode, the plurality of symbol display columns are varied at the normal speed and sequentially stopped and displayed.

For example, when the variation method determining means determines that the symbol variation mode is the reach stop mode, the plurality of symbol display columns are fluctuated at a normal speed and sequentially stopped and displayed, and finally the symbol display to be stopped. For columns,
After the speed is changed to the reach fluctuation display speed lower than the normal speed, the operation is stopped. For example, when the variation method determining means determines the symbol variation mode to be the special reach stop mode, the plurality of symbol display columns are varied at normal speed and sequentially stopped and displayed, and finally the symbol display columns to be stopped are displayed. Is changed to a special reach variation display speed that is lower than the reach variation display speed, and then stopped.

Further, the symbol variation control means causes the symbol variation display means to stop and display the stop symbol determined by the stop symbol determination means (for example, twelfth step S212). The ball game machine according to claim 2 is a counter reset means for resetting the counter value of the change number counter (for example, the tenth step S210, on the condition that the symbol change display is performed in the special reach stop mode). Eleventh step S211)
It is characterized by having.

Therefore, according to the second aspect of the present invention, when the symbol change display is performed by the symbol change display means in the special reach stop mode, the counter of the number of changes is set. Is reset to "0" (for example, the tenth step S210 and the eleventh step S211). When the counter value is reset to “0” by the counter reset unit, the change number counter again counts the number of symbol changes by the symbol change display unit from “0”.

For this reason, it is possible to set the symbol variation display means in the symbol variation display means to a special reach stop mode at a periodic interval of every variation number.

Further, below the variable winning device 110, there is provided a collecting port 120 for collecting game balls dropped on the lower edge of the guide rail 12. Next, the design of the pachinko machine having the above-mentioned structure is provided. The outline of the operation related to the determination of the variation method will be described with reference to FIG. First, in the first step S201,
It is determined whether the stored random number value is a hit or not. This determination is made by the stopped symbol determination means. In this determination, first, random number generating means for determining a stop symbol is sequentially generated. For example, from the random number of a number from 0 to 16383 in decimal, the random number extracting means On the condition that is detected, one random value is extracted and stored, and the stopped symbol determining means is configured such that the previously stored random value is stored in advance and the stopped symbol determining random number generating means is used. The random number value extracted should be a special prize mode by referring to a prize determination table including a prize area to be set as a special prize mode and a non-prize area other than the prize area in the entire area where the generated random value takes. This is performed by determining whether or not the numerical value corresponds to the winning area, that is, whether or not the random number value is a hit.

If it is determined in the first step S201 that the stored random number value is not a hit, the process proceeds to a second step S202. In the second step S202, the stop symbol determining means determines whether the stop symbol is a stop symbol. Is not a hit symbol.
That is, the stop symbol determining means determines the stop symbol to be a symbol other than the hit symbol.Here, the "hit symbol" is a state in which the symbol variation in all symbol display columns 60 to 62 in the symbol variation display device 50 is stopped. This means that the combination of symbols stopped and displayed on any of the five virtual lines L1 to L5 is a combination of symbols constituting a special prize mode. As shown in (A) to (E) of FIG. 5, the case where "777" is aligned with the virtual lines L1 to L5 corresponds to this case.

Therefore, the symbols other than "hit symbol" means that the symbol variation in all symbol display columns 60 to 62 in the symbol variation display device 50 is stopped and stops on the five virtual lines L1 to L5. This indicates a case where the displayed combination of all stopped symbols is other than the above “hit symbol”. On the other hand, if it is determined in the first step S201 that the stored random number value is a hit, then in the third step S201
Proceeding to 203, in the third step S203, the stopped symbol determining means determines the stopped symbol as a winning symbol.

When the symbols to be stopped are determined in the second step S202 and the third step S203, the process proceeds to a fourth step S204. In the fourth step S204, the counter of the variation counter is incremented by one. That is, by incrementing the counter value of the number of times of change by one, the number of times of change of the symbol by the symbol change display device is counted. In the fourth step S204, when the counter value of the fluctuation number counter is incremented by one, the process proceeds to the next fifth step S205. In the fifth step S205, is the stop symbol determined by the stop symbol determination means "reach"? It is determined whether or not. This determination is made by the lottery table selecting means. The lottery table selecting means determines whether the combination of the symbols stopped and displayed in the symbol columns other than the symbol column for which the variation of the symbol is stopped last among the stopped symbols is included in the combination of the symbols constituting the special prize mode. That is, it is determined whether or not the stop symbol is “reach”. In the present embodiment, the case where the stop symbol is “reach” means that the symbols on the one of the lines L1 to L5 are not changed while the symbols on the rotary reels 80 and 82 excluding the central rotary reel 81 are stopped changing. Means that there is a combination of symbols that constitutes a special prize mode.

If the stop symbol is determined to be "reach" in the fifth step S205, the process proceeds to the next sixth step S206. In the sixth step S206, the stop symbol is a hit, that is, a special prize mode. The symbol in the symbol display column 61, which is a combination of the symbols constituting the symbols or the stop symbol is before and after the hit, that is, the symbol symbol in the symbol display column 61 which stops the variation of the symbol at the end, and one symbol in the symbol combination constituting the special prize mode. It is determined whether or not it is a case where the rotation of the rotation reels 80 to 82 is shifted back and forth by the distance. This determination is made by the lottery table selecting means.

Here, the symbol of the symbol row 61 for which the symbol variation is stopped lastly is the symbol in the combination of the symbols constituting the special prize mode and the symbol in the moving direction of the rotary reels 80 to 82 by one symbol. When the pattern is shifted, as shown in FIG. 6, the symbols in the symbol display columns 60 to 62 that stop the change of the symbol at the end are
In the symbol display row that could be a combination of the symbols constituting the special prize mode, if it is shifted by one symbol before and after in the rotation direction of the spinning reels 80 to 82, the symbol combination constituting the special prize mode is The one that matches.

At the sixth step S206, the stop symbol is
If it is determined to be a hit or before and after the hit, the process proceeds to the next seventh step S207, and in the seventh step S207,
It is determined whether or not the counter value of the variation counter is 150 or more. This determination is made by the lottery table selecting means, and the lottery table selecting means monitors the counter value of the variation counter.

If it is determined in the seventh step S207 that the counter value of the variation counter is 150 or more, the process proceeds to the next eighth step S208, where the fourth lottery table is selected. The fourth lottery table indicates that, among all regions where the random number value generated by the random number
The area for performing the reach stop mode is 5%, and the area for performing the special reach stop mode is 95%. For example, when generating a random number having a numerical value from 0 to 99, the variation method lottery random number generating unit is a region for performing a reach stop mode from 0 to 4 and a special reach stop mode from 5 to 99. It is an area to be performed.

When the fourth lottery table is selected in the eighth step S208, the process proceeds to a ninth step S209. In the ninth step S209, the random number for the variation method lottery and the fourth
Using the lottery table, the change method determining means determines the change method. The determination of the variation method is performed by, for example, using a random number from 0 to 99, which is sequentially generated from the variation method lottery random number generation means, by the variation method lottery random number extraction means. Is extracted.

Then, the random number value extracted by the random number extracting means is compared with the fourth random selection table selected by the random selection table selecting means, and the extracted random number value belongs to an area in which the reach stopping mode is performed. , Or belongs to an area in which the special reach stop mode is performed. In the sixth step S206, since the fourth lottery table is selected, in the determination of the variation method using the fourth lottery table, the variation method is determined to have the special reach stop mode with a 95% probability. The Rukoto.

When the variation method is determined in the ninth step S209, the process proceeds to the next tenth step S210, and it is determined whether the variation method is a special reach stop mode. This determination is performed by the counter reset unit, and the counter reset unit monitors whether the variation method determined by the variation method determination unit is determined to be in the special reach stop mode.

When it is determined in the tenth step S210 that the variation method is the special reach stop mode, the process proceeds to an eleventh step S211 and the counter reset means sets the counter value of the variation number counter to Clear to 0, that is, reset. The eleventh step S211
Then, when the variation counter is cleared to 0, the process proceeds to the twelfth step S212. In the twelfth step S212, the stop mode determined by the variation method determination unit is determined based on the variation mode stored in the variation mode storage unit. The design is changed accordingly.

When the stop mode is determined to be the normal stop mode, the symbol variation control means outputs a plurality of symbol display columns 60 to 62.
Are sequentially stopped and displayed at the normal changing speed. Further, when the stop mode is determined to be the reach stop mode, the symbol variation control means sequentially stops and displays the plurality of symbol display columns 60 to 62 at the normal variation speed, and finally stops the symbol display column. About 61, it stops after changing to the reach fluctuation display speed lower than the said normal fluctuation speed.

When the stop mode is determined to be the special reach stop mode, the plurality of symbol display columns 60 to 62 are sequentially stopped and displayed at the normal fluctuation speed, and the symbol display column 61 to be stopped last is displayed. Is stopped after the special reach fluctuation display speed, which is lower than the reach fluctuation display speed, is changed. On the other hand, the ninth step S
If it is determined in 209 that the mode is not the special reach stop mode, the process proceeds to the twelfth step S212.

On the other hand, if it is determined in the seventh step S207 that the counter value of the variation counter is equal to or smaller than 150, the process proceeds to a thirteenth step S213, and the third lottery table is selected. The third lottery table shows that, of all the regions where the random number value generated by the variation method random number generating means takes a value, a region where the reach stop mode is performed is 51%, and a region where the special reach stop mode is performed is 49%. Has become. For example, when generating a random number having a numerical value from 0 to 99, the variation method lottery random number generating means is a region for performing a reach stop mode from 0 to 49, and a special reach stop mode from 50 to 99. It is an area to be performed.

In the sixth step S206,
If it is determined that the symbol to be stopped, that is, the stop symbol determined by the stop symbol determination means is “reach” but is not a hit or before and after the hit, a fourteenth step S214
The second lottery table is selected. In the second lottery table, the area in which the reach stop mode is performed is 100% of the entire area in which the random number value generated by the variation method random number generation means takes. When generating a random number having a numerical value of, for example, 0 to 99, the variation method lottery random number generating unit is an area in which the reach stop mode is performed from 0 to 99.

In the fifth step S205,
When it is determined that the stop symbol is not “reach”, the process proceeds to a fifteenth step S215, and the first lottery table is selected. In the first lottery table, out of all the areas taken by the first lottery table, 100% of the areas are changed in the outlier, that is, the area where the normal stop mode is performed. When generating a random number having a numerical value from 0 to 99, for example, the variation method lottery random number generating means is an area where the normal stop mode is performed from 0 to 99.

In the above-described embodiment, the number of times the symbol variation is started by the symbol variation display device 50 is counted by the variation number counter, and if it is determined that the counter value of the variation number counter is 150 or more, It has been described that either the reach stop mode or the special reach mode is selectively selected and the fourth lottery table in which the appearance rate of the special reach mode is set higher than the reach stop mode is selected. .

However, in the second embodiment, a reach variation frequency counter for counting the number of times that the symbol variation display device 50 has performed the reach stop mode (not including the special reach stop mode) is provided. When it is determined that the counter value of the number counter is 10 or more,
The fourth lottery table may be selected. Next, the operation of the second embodiment of the pachinko machine as a ball game machine will be described with reference to the flow shown in FIG.

The description of the parts common to the operation flow described above is omitted. 20th step
At 320, it is determined whether or not the counter value of the reach variation counter for counting the number of reach variations is 10 or more. This determination is made by the lottery table selecting means, and the lottery table selecting means monitors the counter value of the reach variation counter.

If it is determined in the twentieth step S320 that the count value of the reach variation counter is 10 or more, the process proceeds to the next eighth step S208, where the fourth lottery table is selected. Also, the twenty-first step S321
Then, it is determined whether or not the variation method is a reach stop mode. This determination is made by the counter reset unit, and the counter reset unit monitors whether the variation method determined by the variation method determination unit is a reach stop mode.

In the above-mentioned twenty-first step S321, when it is determined that the variation method is the reach stop mode,
Next, proceeding to a twenty-second step S322, the counter reset means increments the counter of the reach variation counter by +1. That is, by incrementing the counter value of the number of reach fluctuations by one, the number of fluctuations of the symbol by the symbol fluctuation display device is counted.

On the other hand, the above-mentioned twenty-first step S321
When it is determined that the variation method is not the reach stop mode, the process proceeds to the tenth step S310. In the first embodiment, the special reach stop mode is used when the counter value of the variation counter exceeds a predetermined number by using the variation counter for counting the number of symbol variations by the symbol variation display means. By selecting the fourth lottery table having a high rate, the lottery probability in the special reach stop mode is improved. Further, in the second embodiment, a reach variation counter that counts the number of times the reach variation mode is performed by the symbol variation display means is used. When the counter value of the reach variation counter exceeds a predetermined number, By selecting the fourth lottery table having a high appearance rate of the special reach stop mode, the lottery probability of the special reach stop mode is improved.

However, in another embodiment, instead of the variation number counter or the reach variation number counter, for example, a fired hit ball number counter for counting game balls fired in the game section 20 from the game ball launching device 40 is provided. In the case where the count value of the number of fired hit balls exceeds a predetermined number, for example, 2000, by selecting the fourth lottery table having a high appearance rate of the special reach stop mode, the lottery probability of the special reach stop mode is improved. Alternatively, a special reach stop mode may be used when an elapsed time counter that counts the elapsed time from the time of power-on is used instead of the power supply and the count value of the elapsed time counter exceeds a predetermined number, for example, 40 minutes. May be improved by selecting the fourth lottery table with a high appearance rate of the symbol, in the above embodiment, the symbol variation display The symbol variation display device 50 provided with the rotating reels 80 to 82 is used as a step, but the symbol variation display means is not limited to this, and a liquid crystal display device or a CRT may be used.

[0051]
