Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine such as a pachinko machine, an arrange ball machine, and a play ball game machine.

[0002]

2. Description of the Related Art In ball game machines such as pachinko machines, in addition to first symbol display means capable of variably displaying the first symbol on a game board,
There is a device provided with second symbol display means capable of variably displaying the second symbol.

In this ball-and-ball game machine, for example, numerical symbols from 0 to 9 are used for three second symbols of the second symbol display means, and each symbol is set on condition that the symbol starting means detects a game ball. The second symbol is changed for a predetermined time by a symbol group of 0-9. Then, when the second symbol after the change stops in a predetermined order, the reach changes in any one of the odd symbol as the special symbol and the even symbol as the non-special symbol, and the second symbol after the change. Is in a specific mode of displaying all the same specific symbols, the first profit state generating means activates variable winning means such as a large winning means to generate a first profit state advantageous to the player. . If the second symbol is an odd symbol that is a special symbol and has a specific mode, after the occurrence of the first profit status or after the end of the first profit status, the second profit status generating means makes the second profit status advantageous to the player. (Probability fluctuation, shortening of fluctuation time, etc.).

Conventionally, in such a ball game machine, a main control board for controlling a game operation determines whether or not a first profit state is to be generated by a game determining means, and the result of the determination is the first profit. In the case where the state is not generated, the reach determining means determines whether or not the reach of the second symbol is changed. If the reach is changed, it is equally determined whether the reach symbol is an odd symbol or an even symbol. After setting, a command such as a symbol change pattern or a stop symbol is transmitted from the main control board to the symbol control board by one-way communication, and the symbol control means on the symbol control board uses the symbol control means to transmit the second symbol based on the command. Control.

In setting a reach symbol, the reach symbol setting means randomly selects random numbers from 0 to 9 and selects one of an odd symbol and an even symbol based on a symbol table having an equal appearance rate based on the random numbers. Is selected and set as the reach symbol. For this reason, whether the reach of the second symbol fluctuates with an odd symbol,
Or, the probability of the reach fluctuation in the even symbols is 柄.

[0006]

In the case where, for example, three second symbols arranged horizontally in the second symbol display means are stopped in the order of left, right, and middle, the stopped symbol after the change becomes a specific mode. At this time, and even in the non-specific mode, when the reach determining means determines that the reach has fluctuated, the reach state is reached in which the same symbols are displayed when the two left and right second symbols stop.

However, conventionally, when it is determined that the reach has fluctuated, the reach symbol setting means assigns ten random numbers from 0 to 9 to each of ten numeric symbols from 0 to 9, and sets any one of the random numbers. , And either the odd symbol or the even symbol is set equally, so that the odd symbol and the even symbol appear with the probability of 1/2 as the reach symbol at the time of the reach change. For this reason, even if it reaches the odd symbol during the fluctuation, it rarely becomes a specific mode finally with the special symbol, and the reliability with respect to the occurrence of the first profit state accompanied by the second profit state. Has a drawback that it is not enough to attract the interest of the player.

For example, if the occurrence probability of a specific mode in which a stopped symbol after a change is a specific mode is set to 1 to 350 and the probability of the reach change is set to 1/10, when the reach change is determined, the odd symbol becomes 1 / Since it comes out with a probability of 2, even if it reaches the odd symbol during the fluctuation, it eventually stops in a non-specific manner with the same probability as the reach fluctuation in the even symbol.

In the case where a so-called re-lottery function for updating a non-special symbol to a special symbol again is provided, the odd symbol in the process of absolutely becoming a specific mode has a lower ratio of a specific mode through reach fluctuations. There is a problem that even when the player reaches the odd symbol during the fluctuation, the player's expectation for the occurrence of the first profit state accompanied by the second profit state is reduced.

The present invention has been made in view of the above-mentioned conventional problems, and provides a ball game machine capable of increasing the reliability of reach fluctuation in a special symbol and evoking a player's interest by the reach fluctuation. Aim.

[0011]

According to the present invention, a symbol starting means 14 and a symbol display means 19 capable of variably displaying a plurality of symbols 21a to 21c on condition that the symbol starting means 14 detects a game ball. And reach determining means 4 for determining whether or not the symbols 21a to 21c are to be reach-fluctuated with a specific symbol.
1 and a first profit state generating means 39 for generating a first profit state advantageous to the player based on the fact that the symbols 21a to 21c are in the specific mode after the reach change in the specific symbol. In the ball game machine, the specific symbol has a special symbol and a non-special symbol, and the reach determination means 41
Is determined to be the reach variation, the symbols 21a ~
Reach symbol setting means 4 for setting the special symbol reach probability when the reach of the special symbol 21c fluctuates in the special symbol lower than the non-special reach probability when the reach fluctuates in the non-special symbol
3 is provided.

The variable winning means 15 is provided with the opening / closing plate 26 on condition that a predetermined time (for example, 30 seconds) elapses after opening or a predetermined number (for example, 10) of game balls wins, whichever is earlier. And the opening and closing operation is repeated up to a predetermined number of times (for example, 16 times) on condition that the game ball passes through the specific area 27.

FIG. 4 is a block diagram illustrating a control system. In FIG. 4, reference numeral 30 denotes a main control board, which is detachably attached to a predetermined portion on the back side of the game machine main body 1, such as a back cover on the back side of the game board 3. Reference numeral 31 denotes a symbol control board, which is detachably attached to a predetermined portion on the back side of the game machine main body 1, such as the back side of the liquid crystal display means 12. The main control board 30 and the symbol control board 31 are formed of separate boards, and are housed in the same or different board cases.

The main control board 30 is mainly for controlling the game operation on the game board 3 side, and is a first game for controlling related to the operation of the first symbol display means 24 and the second symbol start means 14. Control means 32, second symbol display means 19,
Second game control means 33 for performing control relating to the occurrence of the first profit state and the second profit state, and the respective game control means 32, 3
A command transmission means 34 for transmitting a command relating to symbol control from 3 to the symbol control board 31 side is mounted. On the symbol control board 31, a first symbol control unit 35 for performing display control on the first symbol display unit 24 side and a second symbol control unit 36 for performing display control on the second symbol display unit 19 side are mounted. I have.

The first game control means 32 determines that the first symbol starting means 13 detects any of the random numbers sequentially generated in accordance with the probability that the changed first symbol has a predetermined mode. It is determined whether or not the first symbol after the change is set to a predetermined mode from the random number value (or whether to activate the second symbol starting means 14) from the random number value, and the symbol is determined according to the determination result. A change command of the first symbol is issued to the first symbol control means 35 on the control board 31 side, and the result of the determination is sent to the second symbol starting means 14.
Is activated, the opening and closing claw 25 of the second symbol starting means 14 is opened for a predetermined time (for example, about 0.5 second) based on the fact that the first symbol after the change becomes a predetermined mode. ing.

In the first game control means 32, for example, when the probability that the first symbol is in the predetermined mode is 1/10, any one of random numbers from 0 to 9 is randomly selected and the random number is selected. The judgment is made based on a numerical value.

The second game control means 33 includes the game lottery means 3
7, game determining means 38, first profit state generating means 39, second profit state generating means 40, reach determining means 41, specific mode symbol setting means 42, reach symbol setting means 43, non-specific mode symbol setting means 44, fluctuation It includes a pattern setting means 45 and the like, and is constituted by a CPU, a ROM, a RAM and the like.

The game lottery means 37 is, for example, a second
When the probability (the probability of occurrence of the first profit state) of the specific pattern 21a to 21c is 1/350, 350 random numbers from 0 to 349 are generated. Numerical values are sequentially generated, and on condition that the second symbol starting means 14 detects a game ball, one of the random numbers is randomly selected. Game determination means 38
The lottery of the game lottery means 37 is determined so that the random number value of the game lottery means 37 is a specific game determination value (for example, a random number value “7”) and is determined to be a specific game (the occurrence of the first profit state). It is determined whether or not to generate the first profit state based on the random number value.

The first profit state generating means 39, when the game determining means 38 determines that the game is a specific game, the second symbols 21a to 21c after the fluctuation of the second symbol display means 19 includes an odd symbol and an even symbol. Based on the fact that it becomes a specific mode (all the same type of symbols) after reach fluctuation with multiple types of specific symbols,
This is for generating a first profit state advantageous to the player. For example, the opening and closing plate 26 of the variable winning means 15 is opened, and a predetermined time (for example, 30 seconds) elapses after the opening,
The open / close plate 26 is closed on condition that a predetermined number (for example, 10) of game balls wins before the predetermined time elapses, and further, on condition that the game balls pass through the specific area 27, a maximum number of predetermined times (for example, 16 times).

The reach determination means 41 is for determining whether or not the reach of the second symbols 21a to 21c is fluctuated during the fluctuation, and the game lottery means 37 determines a random number value other than the specific game determination value (outlier random number value). ), And when the game determining means 38 determines that the game is a non-specific game other than the specific game, if the probability of the reach fluctuation is 1/10, for example, one of ten random numbers is randomly selected. Of the random number values sequentially generated based on the reach variation probability of the second symbol 21a, and when the random number value is the reach determination value, it is determined that the second symbols 21a to 21c are to be varied. I have.

The specific design symbol setting means 42, when the determination result of the game determination means 38 is a specific game determination, the type of the specific symbol (odd symbol, even symbol) in which the changed second symbols 21a to 21c are in the specific mode. Is selected and set by random number lottery based on a predetermined symbol table. The specific mode symbol setting means 42 selects and sets either an odd symbol or an even symbol with a predetermined probability (eg, 1/2).

The reach symbol setting means 43 determines that the game determination means 38 determines that the game is a non-specific game determination and the reach determination means 4
When 1 is determined to be a reach fluctuation, the second symbols 21a to 21a
1c is for selecting and setting the type of the reach symbol when the reach varies, and the special symbol reach probability when the second symbols 21a to 21c vary in the reach with the special symbol (odd symbol) is represented by a non-special symbol ( (Even symbols) has a symbol table that lowers the non-special symbol reach probability when the reach fluctuates, and selects and sets the special symbols and non-special symbols when the reach fluctuates by random lottery based on the symbol table. Has become.

Assuming that the special symbol reach probability is 5/100 as shown in FIG. 5, for example, as shown in FIG. 5, 20 out of a random number group including 100 random numbers from 0 to 99 generated sequentially. For example, the random number value for each eye is set as a random number value for odd symbols, and the random number value for odd symbols corresponding to the plurality of odd symbols of “1”, “3”, “5”, “7” and “9” is It is configured to be distributed almost evenly with respect to all random value groups. When the reach of the second symbols 21a to 21c fluctuates in the reach symbol selected by the reach symbol setting means 43, the non-specific modes are displayed for the second symbols 21a to 21c after the variation.

The non-specific mode symbol setting means 44 determines whether the second symbols 21a to 21c after the fluctuation have been determined when the result of the non-specific game determination by the game determining means 38 is a non-specific game determination and the reach determining means 41 determines that there is no reach fluctuation. This is for selecting and setting the type of the non-specific symbol in the non-specific mode by random number lottery or the like based on a predetermined symbol table. In addition, the non-specific mode symbol setting means 44 includes the left and right second symbols 21a, 21c.
Is designed to select and set different types of symbols.

When the game determining means 38 determines that the game is a specific game, the variation pattern setting means 45 executes the second symbols 21a to 21a.
When the reach determination unit 41 determines that the reach variation has occurred in the specific mode variation pattern from the start of the variation to the stop in the specific mode, the second symbols 21a to 21c stop in a non-specific manner via the reach variation from the start of the variation. When the reach determination means 41 determines that there is no reach variation, the reach-less variation until the second symbols 21a to 21c stop in a non-specific manner without a reach variation from the start of the variation. Each pattern is selected and set by random number lottery or the like.

The second profit state generating means 40 determines whether or not the second symbols 21a to 21c after the change have an odd number (special symbol) in a specific mode, after the end of the first profit state (or the first profit state). After the occurrence of the state) to generate a second profit state advantageous to the player, and the second symbol 21a after the change
The probability variation means 46 is configured to vary the probability (the probability of occurrence of the first profit state) from the normal probability (low probability) to the high probability. The probability changing unit 46 increases the number of specific game determination values of the game determining unit 38 and changes the probability from the normal probability to the high probability to increase the probability of the specific mode.

In this embodiment, the probability varying means 46
When the probability is high, the number of specific game determination values is increased by a factor of ten to increase the probability of occurrence of the specific mode from 1/350 to 1/35. Further, the second profit state generating means 40 and the probability changing means 46 generate the first profit state a predetermined number of times (next time or about 3 to 5 times from the next time), and generate the second symbols 21 a to 21.
The second profit state (high probability) is terminated when a predetermined number of times (approximately 50 times) of c has changed or a predetermined time has elapsed.

The command transmission means 34 is connected to the main control board 30
To transmit a command from the first game control means 32 to the first symbol control means 35 to the symbol control board 31 by one-way communication. Each symbol setting means 42 to of the control means 33
44, a symbol command for designating the type of each of the second symbols 21a to 21c, the variation pattern command set by the variation pattern setting means 45, and the second symbol 2
A stop command for stopping 1a to 21c is transmitted to the second symbol control means 36.

The first symbol control means 35, based on the command from the first game control means 32, the first symbol display means 2
This is for changing the first symbol of No. 4 for a predetermined time and then stopping in a predetermined mode or a non-predetermined mode after the fluctuation. The second symbol control means 36 fluctuates each of the second symbols 21a to 21c in a predetermined fluctuation pattern for a predetermined time based on a symbol command, a fluctuation pattern command, and a stop command from the second game control means 33, and changes the fluctuation. This is for stopping by a stop command at a predetermined stop symbol specified by the symbol command later.

The second symbol control means 36 includes a display result updating means 47 as a part thereof. The display result updating means 47 displays the specific mode in the non-special symbol through the reach state during the fluctuation of the second symbols 21a to 21c for a predetermined time, and then changes the second symbols 21a to 21c again to display the final symbols. This is for updating the result to a specific mode with a special symbol.

The display result updating means 47 is provided for, for example, when the second symbols 21a to 21c of the specific mode set by the specific mode symbol setting means 42 are special symbols, the second symbols 21a to 21c in the middle of the symbol change. Is temporarily stopped for a predetermined time with a different special symbol or a non-special symbol, and thereafter is changed again to finally update the temporarily stopped symbol and a special symbol different in type, and a specific mode symbol setting means 42 When the second symbols 21a to 21c of the specific mode set on the side are non-special symbols, the second symbol 21a is temporarily stopped for a predetermined time at a non-special symbol different from the designated non-special symbol, and then temporarily stopped and then changed again. It has a function of updating to a non-special symbol that has been set in a targeted manner, and is configured to select any one of them from a random number table or the like.

In the above-mentioned ball game machine, at the time of a game, the firing handle 9 of the firing means 8 is operated to cause the firing means 8 to sequentially fire the game balls along the guide rail 10 toward the game board 3. Then, the game ball fired on the upper side of the game board 3 enters the game area 11 of the game board 3,
Normal winning means 16-18 while falling along the board
Or falls down while passing through the first symbol starting means 13.

When the game ball passes through the first symbol starting means 13, the first symbol of the first symbol display means 24 fluctuates for a predetermined time under the control of the first game control means 32 and the first symbol control means 35, and the predetermined symbol fluctuates. Stop in a mode or non-predetermined mode. And
When the first symbol after the change becomes the predetermined mode, the opening / closing claw 25 of the second symbol starting means 14 is opened, and the second symbol starting means 14 is opened.
In a state in which the game ball can be won or in a state where it can be easily won.

When the game ball wins the second symbol starting means 14, the game lottery means 37 draws a random number value generated, and the game determination means 38 generates a specific game (first profit state) from the random number value. It is determined whether or not. Game determination means 38
Is determined to be a specific game, the specific mode symbol setting means 42 sets the type (special symbol or non-special symbol) of the specific symbol in which the changed second symbols 21a to 21c become the specific mode, and sets the variable pattern setting means. 45 is the second symbol 21a-21
After setting the variation pattern of c, the command transmitting unit 34 transmits the variation pattern command, the symbol command, and the stop command from the main control board 30 side to the symbol control board 31 side.

On the symbol control board 31 side, the second symbol control means 36 receives and analyzes each command from the command transmission means 34, and displays the second symbols 21a to 21c of the second symbol display means 19 according to each command. Control the second symbol 21
a to 21c fluctuate for a predetermined time in a predetermined fluctuation pattern and stop. In this case, under the control of the display result updating means 47, the second symbols 21a to 21c display the specific mode in a special symbol or a non-special symbol for a predetermined time, and then change again to change the specific mode symbol setting means 42. Finally stops at the special symbol or non-special symbol set in.

For example, the type of the second symbols 21a to 21c set by the specific mode symbol setting means 42 is the special symbol "7", and the second symbols 21a to 21c set by the random number table or the like of the display result updating means 47. When the temporary stop symbol of 21c is a non-special symbol “4”, each of the second symbols 21a to 21
1c, after changing in a predetermined change pattern from the start of change as shown in FIG. 6A, the left and right second symbols 21a and 21c become non-special symbols "4" as shown in FIG. 6B. After the reach state, the temporary stop is performed as shown in FIG. 6C, and all the second symbols 21a to 21c display the specific mode "4.4.4." Of the non-special symbol "4".

The second symbols 21a to 21c are:
When the specific mode “4 • 4 • 4” is displayed for a predetermined time, FIG.
The fluctuation starts again as shown in (D), and finally, as shown in FIG. 6 (E), all the second symbols 21a to 21c show the special mode "7 / 7.7" of the special symbol "7". indicate.

As described above, the second symbols 21a to 21c temporarily stop temporarily in the specific mode of the non-special symbol, and start to change again to specify the non-special symbol or the special symbol set by the specific mode symbol setting means 42. If it is configured to finally stop in the aspect, even if the temporary stop symbol is a non-special symbol, it may be updated to a special symbol by subsequent re-fluctuation, thereby significantly improving the interest of the player Can be done.

Since the display result updating means 47 is located on the symbol control board 31, the final symbol command of the second symbols 21a to 21c is transmitted from the main control board 30 to the symbol control board 31. Can temporarily stop the second symbols 21a to 21c, update the display result, and the like in the process on the symbol control board 31 side, and can easily transmit a command from the main control board 30 to the symbol control board 31.

When the changed second symbols 21a to 21c stop in a specific manner, a first profit state is generated by the first profit state generating means 39, and the opening / closing plate 26 of the variable winning means 15 is opened forward. The game ball falling from above wins the variable winning means 15 via the open / close plate 26. The variable winning means 15 closes the opening / closing plate 26 when a predetermined time has elapsed from the opening or when a predetermined number of game balls have been won by that time.
, The opening / closing plate 26 is opened again, and the opening / closing operation is repeated up to 16 times. Therefore, when the first profit state occurs, the player can receive payout of prize balls according to the winning number of the game balls, and can enjoy great profit.

In the case where the second symbols 21a to 21c are in a special mode in a special symbol, the second profit state is generated by the second profit state generating means 40 after the first profit state is generated by the first profit state generating means 39. Then, the probability changing means 46 changes the probability of occurrence of the specific mode (first profit state) from the normal probability to the high probability. Thereby, the second symbol 21a after the change
21c becomes the specific mode again, and the possibility that the first profit state occurs again becomes very large, so the possibility that the player can enjoy great profit again becomes large.

If the result of the determination by the game determination means 38 is a non-specific game that does not generate the first profit state, the reach determination means 41 determines whether or not the reach is changed. When the reach determination means 41 determines that the reach does not change, the non-specific design symbol setting means 44 sets the type of the non-specific design after the fluctuation of the second symbols 21a to 21c, and the fluctuation pattern setting means 45 sets the reach. Set a fluctuation pattern without fluctuation,
The command transmitting unit 34 transmits the variation pattern command, the symbol command, and the stop command to the second symbol control unit 36. As a result, the second symbol control means 36 controls the second symbols 21a to 21c of the second symbol display means 19,
The symbols 21a to 21c fluctuate for a predetermined time in a fluctuation pattern without reach fluctuation and stop in a non-specific manner.

If the result of the reach determination means 41 is reach fluctuation, the reach symbol setting means 43 sets the type of the reach symbols of the second symbols 21a to 21c using the symbol table, and the fluctuation pattern setting means 45 sets the reach pattern. The variation pattern is set, and the command transmission unit 34 transmits the variation pattern command, the symbol command, and the stop command to the second symbol control unit 36. As a result, the second symbol control means 36 makes the second symbols 21a to 21
c, and the second symbols 21a to 21c are, for example, as shown in FIG.
As shown in (A) and (B), or (C) and (D), the reach is varied in a predetermined special symbol or non-special symbol or reach variation pattern, and finally the vehicle stops in a non-specific manner.

As described above, the second symbols 21a to 21c are stopped in a non-specific manner after reaching the specific symbol or the non-specific symbol set by the reach symbol setting means 43 as the reach symbol. However, the reach symbol setting means 43 is a symbol table that makes the special symbol reach probability when the second symbols 21a to 21c fluctuate in the special symbol lower than the non-special symbol reach probability when the reach fluctuates in the non-special symbol. The type of the left and right second symbols 21a and 21c at the time of the reach change, that is, the type of the reach symbol is selected and determined based on the symbol table.

For example, in this embodiment, the special symbol reach probability is 5/100, and the non-special symbol reach probability is 9/100.
It is much lower than 5/100, and special symbols and non-special symbols are selected and set at a ratio of 1:19 with probability. As a result, the reach symbol setting means 43 is
The possibility of selecting a special symbol as shown in FIGS. 7A and 7B is lower than the possibility of selecting a non-special symbol as shown in FIGS. 7C and 7D.

Therefore, the reason why the second symbols 21a and 21c temporarily reach the special symbol reach during the fluctuation of the second symbols 21a to 21c is determined by the game determination means 38 to be a specific game (the occurrence of the first profit state). Then, the specific mode symbol setting unit 42 sets the special symbol, and the case where the reach symbol setting unit 43 sets the special symbol as the reach symbol. For this reason, if the special symbol reach is reached, the probability (probability) that the special symbol will become a specific mode after the change increases, the reliability of the special symbol reach becomes higher than before, and the interest of the player is improved. Can be done.

As described above, one embodiment of the present invention has been described in detail, but the present invention is not limited to this embodiment. For example, in the embodiment, the second profit state generating means 40
As the second profit state, the second symbols 21a to 21f after the change
21c illustrates a probability variation method in which the probability of the specific mode (the probability of occurrence of the first profit state) is changed from the normal probability to the high probability, but instead of this probability variation method, the first symbol and / or A time-saving method for reducing the fluctuation time of the second symbols 21a to 21c from the normal time to a shorter time may be adopted, or the probability variation method and the time-saving method may be used together.

Each numerical value in the embodiment is merely an example,
For example, the special symbol reach probability may be lower than the non-special symbol reach probability. Also, the special symbol reach probability may be significantly lower than the non-special symbol reach probability. If the reach is changed by at least one type of special symbol, the symbol table may be configured so that the reach is always in a specific mode after the change. The display result updating means 47 may be provided on the main control board 30 side or may be omitted. Further, in the embodiment, the pachinko machine including the first symbol display means 24 and the second symbol display means 19 is exemplified, but the first symbol display means 24 may be omitted.

The second symbol display means 19 includes a plurality of symbol display sections 20a to 20c, and each of the symbol display sections 20a to 20c.
What is necessary is just to be able to variably display the second symbols 21a to 21c on 20c. Also, the symbol display sections 20a to 20c
May be fixedly provided in one place, or the liquid crystal display means 1
The symbol display sections 20a to 20c may move within the display area of No. 2. The second symbols 21a to 21c may be a symbol group including a plurality of specific symbols, and may be changed by scrolling or the like. In addition, the present invention can be similarly implemented not only in pachinko machines but also in various ball game machines such as arrange ball machines and sparrow ball game machines.

[0057]

According to the present invention, the symbol starting means 14,
On the condition that the symbol starting means 14 detects a game ball, a symbol display means 19 capable of variably displaying a plurality of symbols 21a to 21c, and whether or not to reach the symbols 21a to 21c with a specific symbol is determined. Reach determination means 41 and symbol 2
In the ball game machine provided with the first profit state generating means 39 for generating the first profit state advantageous to the player based on the fact that 1a to 21c become the specific mode after the reach change in the specific symbol, If the design has a special symbol and a non-special symbol, and the reach determination means 41 determines that the reach is changed, the special symbol reach probability when the symbols 21a to 21c change in reach in the special symbol is the reach in the non-special symbol. Since the reach symbol setting means 43 is provided to lower the probability of non-special reach when fluctuating, there is an advantage that the reliability of the reach fluctuation in the special symbol is increased and the interest of the player can be aroused by the reach fluctuation.
