Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine in which a special prize advantageous to a player is generated when a predetermined condition is satisfied in a game in which a ball is hit on a game board. Here, the gaming machine
It mainly refers to pachinko machines.

[0002]

2. Description of the Related Art Conventionally, various types of pachinko machines have been known as this kind of game machines. On the game board surface of the pachinko machine, a main role for determining a model and enhancing playability is arranged. As a representative main accessory, a variable display device including a liquid crystal screen or the like is known.
A device provided with such a variable display device is generally called a fever device.

[0003] In a fever machine, when a ball wins in a starting winning opening established on a game board, various symbols are scroll-displayed on the variable display device. Then, when the symbol combination after the scroll is stopped becomes a big hit display, a special prize (so-called fever) is generated, and the variable winning opening is set to be opened and closed a predetermined number of times.

The variable display device generally has three display columns arranged in a horizontal line, and the symbols stopped and displayed in each display column are all the same, such as "1,1,1". Then, a jackpot was displayed and a special prize was generated. In addition, when the symbols are arranged in a predetermined specific symbol such as “7, 7, 7”, the special prize is generated, and the probability that the same symbol is aligned in the next display of the variable display device increases. Some models do.

[0005] More specifically, when a ball wins in the starting winning opening, a random lottery using random numbers is executed by software control. According to such a lottery result, whether or not the same symbols are aligned on the variable display device, whether or not a special prize is generated,
It has been set so that whether or not there is a probability fluctuation is determined all at once.

[0006]

In the above-mentioned conventional fever machine, whether or not a special prize is generated and whether or not a probability change occurs are determined uniformly by one random lottery. Therefore, despite the fact that the display result of the variable display means is a jackpot display, it is often immediately understood that the probability variation cannot be expected.

[0007] The result of the symbol-changing game is a jackpot display because it is fixed to a strict fixed probability except when the probability is changed, and it is difficult to have a sense of expectation in the appearance of the jackpot display. Moreover, when the condition of the probability fluctuation is satisfied, the probability actually changes from the next symbol fluctuation game, and is maintained at a constant high probability uniformly for a predetermined period. As described above, there is a problem in that the determination of the probability fluctuation is poor in the game property and somewhat lacking in interest.

The present invention focuses on the above-mentioned problems of the prior art. Each time a symbol-changing game is executed, the probability of the result being a big hit display is changed. It is an object of the present invention to provide a gaming machine that can enhance the interest in a symbol variation game.

The order in which the display operation starts or ends on each display unit 31 is, for example,
The order of the center, left, right, etc. may be set in advance for each row. Various images such as numbers, characters, symbols, and symbols are prepared in advance as the symbols.

As a result of the symbol change game, any one of three lines vertically, horizontally, and diagonally on the display unit 31
A case where all three symbols are identical is defined as a jackpot display. Before the jackpot display is determined, the state where the symbols stopped on the other two display units 31 except for one display unit 31 on any one of the lines corresponds to the reach display.

When the result of the symbol change game is finally determined to be a big hit display, a special prize in which the variable prize device 50 described later is repeatedly opened and closed up to a predetermined number of times is generated. If, as a result of the symbol change game, it is not finally determined to be the big hit display, all of the hits are displayed. In addition, when the jackpot display is confirmed, the color of each display unit 31 may be changed or blinked to notify the player that a special prize will occur.

As shown in FIG. 3, the probability display device 35 visually displays the probability of being determined to be the big hit selected during the symbol change game. The probability display device 35 includes a screen that indicates the selected probability in characters, and may be specifically configured by a liquid crystal display or the like.

More specifically, the probability display device 35 is set so that the probability of a big hit display is displayed in characters during the symbol change game. Here, as characters, as shown in FIG. 4, "normal", "probable change",
Three types of "ultra probable change" are defined.

When "normal" is displayed on the probability display device 35, the probability of the jackpot display is 1/400,
The probability of displaying "probable change" is 1/200. In addition, the probability when “Ultra probable change” is displayed is 1
It is 1/100. In addition, as one form of display, for example, when "probable change" and "ultra probable change" are selected, control is performed so that the reach display is always performed during the symbol change game, and when the reach display is performed, Alternatively, the probability display device 35 may be set to display “probable change” or “ultra probable change”.

Also, instead of displaying the character corresponding to the selected probability immediately, for example, even if "probable change" is selected in advance, the character is changed from "normal" to "probable change". The display may be controlled or the display may be controlled so as to change from “normal” to “ultra probable” to “probable”. In this way, if the display is controlled in the probability display device 35 so that the previously selected probabilities are finally stopped after the various probabilities change, the interest in the game can be further enhanced.

The reserved ball display device 40 displays the number of pending symbol fluctuating games that are not executed when a ball is won in the start winning port 20 during the occurrence of a symbol fluctuating game or a special prize. The reserve ball display device 40, based on a signal from the game control device 100 described later, the game control device 100
Is set to be displayed.

More specifically, in the lottery executing means 112, when a probability of 1/400 is selected by the probability setting means 111, a lottery using the symbol random number table 1 shown in FIG. 5 is executed. A jackpot with a probability of 1. The probability setting means 111 sets the probability 200
When 1/1 is selected, a lottery using the symbol random number table 2 is executed, and when 1/100 of the probability is selected by the probability setting means 111, a lottery using the symbol random number table 3 is executed. It is supposed to be. The symbol random number signal output from the lottery executing means 112 is once stored in the RAM 130,
And the special prize generating means 116. The symbol random number tables 1 to 3 used by the lottery executing means 112 are stored in the ROM 12
0 is stored.

The right holding means 113 is provided with the starting winning opening 2
When the ball wins at 0, it is determined whether or not the symbol fluctuation game or the special prize is occurring, and if the symbol fluctuation game or the special prize is occurring, the control for temporarily suspending the execution of the new symbol fluctuation game is performed. Is what you do. The number of execution rights of the symbol-changing game held here is displayed on the reserved ball display device 40 up to a maximum of four under the control of the right holding means 113 similarly. Specifically, the number of suspended execution rights is indicated by the number of lighted display lamps 41 on the reserved ball display device 40.

The symbol change execution means 114 is a start winning opening 2
When a ball wins at 0, a symbol change game in which one of the symbols is stopped is started after each symbol is changed on each display unit 31 of the variable display device 30 so as to be switched. The symbol change execution means 114 appropriately controls the display content of the symbol change game according to the lottery result of the lottery execution means 112.

The display contents in the symbol variation game are various combinations of symbols corresponding to the jackpot display (determined via the reach display) and other loss displays according to the lottery result of the lottery executing means 112. Is programmed in advance so as to be stopped and displayed.

The probability display control means 115 causes the probability display device 35 to display a character (see FIG. 4) corresponding to the probability selected by the probability setting means 111 during the symbol change game. Under the control of the probability display control means 115, when reach display is performed during the symbol change game, each character may be displayed on the probability display device 35. Also, after each character is changed and changed, the display control may be performed so that the preselected one stops last. Of course, the probability itself may be displayed as a number instead of a character corresponding to the probability.

The special prize generating means 116 executes a control for generating a special prize when the result of the symbol change game is a big hit, specifically, when the lottery result of the lottery executing means 112 is a big hit. . Here, the special prize is
That is, the movable plate 15 of the variable winning device 50 repeatedly opens and closes up to 16 rounds. The special prize generating means 116 includes a solenoid circuit for driving the solenoid 52 of the variable winning device 50 according to a game control program.

In the ROM 120 of the game control device 100, game control program data for controlling the variable prize device 50 and the like, display control program data relating to the display contents of the variable display device 30, and prizes for various bonuses are produced. Fixed data such as a lighting pattern of the display lamp 18 and a sound generation pattern from a speaker are stored. The RAM 130 temporarily stores winning data and the like related to the game, including signals from various winning ports.

As shown in FIG. 1, a prize ball payout means 60 is also provided inside the gaming machine 10. The prize ball payout means 60 includes a prize ball payout counter 61, a payout setting means 62 for setting a predetermined number of prize balls for each winning opening, and a calculation means 63 for counting the number of prize balls. The winning ball payout means 60 is also connected to the CPU 110 of the game control device 100 via a signal line.

Next, a gaming method using the gaming machine 10 will be described. In FIG. 2, the player launches a ball on the game board surface 11 by rotating the handle 12, and
Compete and enjoy the prize winning of each of the hits and the like. In FIG. 6, when the ball wins the start winning opening 20 during the progress of the game (Y in S100), the start winning detection switch 21 outputs a start winning signal to the game control device 100.

At this time, if a symbol change game is not in progress or a special prize is being generated by the variable display device 30 described later (N in S 101), the symbol change is performed by the variable display device 30 based on a signal from the symbol change execution means 114. A game is started (S102).

Even if the ball does not win in the starting winning opening 20 (N in S100), if the right of the unexecuted symbol change game is reserved (Y in S103), the symbol change is performed as described above. Unless a game or special prize is occurring (S10
1 and N), a symbol change game is started (S102).

The right executed at this time is subtracted and displayed by turning off the holding lamp 41 of the holding display device 40 shown in FIG. On the other hand, if the right is not reserved (S103
N), the symbol change game is not executed, and the variable display means 30
Remains on the standby screen (S4).

When a ball is won in the starting winning port 20, if a symbol change game is in progress or a special prize is being generated (Y in S 101), the R of the game control device 100 is
The rights stored in the AM 130 are held ball display device 40
If it is less than the maximum value 4 that can be displayed (Y in S105),
The right to execute the symbol fluctuation game up to four times is reserved (S106).

The number of rights reservation at this time is added and displayed by lighting of the reservation lamp 41 of the reservation ball display device 40.
Further, in the state where the right is held up to the maximum of four (N in S105), even if the ball wins in the starting winning opening 20 as described above, the right to execute the symbol change game is discarded. (S107). The above-mentioned right reservation is executed by the right reservation unit 113.

Next, in the flowchart shown in FIG. 7, immediately after the above-described symbol change game is started, the probability for determining the result of the symbol change game to the jackpot display is selected by the probability setting means 111. Here, three types of probabilities are prepared, namely, 1/400, 1/200, and 1/100, and one of the probabilities is randomly selected from these for each symbol variation game.

When a probability of 1/400 is selected by the probability setting means 111, the lottery using the symbol random number table 1 shown in FIG. Also, the probability setting means 111 uses the 1/200
Is selected by the lottery executing means 112, the lottery using the symbol random number table 2 is executed.
Further, when a probability of 1/100 is selected by the probability setting means 111, the lottery using the symbol random number table 3 is executed by the lottery executing means 112.

When a probability is selected by the probability setting means 111, the probability display control means 1
By the control of No. 15, a character corresponding to the actually selected probability is displayed on the probability display device 35. For details, probability 40
When 1/0 is selected, “normal” is displayed on the probability display device 35. When the probability of 1/200 is selected, “probable change” is displayed, and when the probability of 1/100 is selected, “ultra probable” is displayed.

If the result of the lottery by the lottery execution means 112 is a big hit (Y in S114), a reach display is made in the symbol change game, and then a big hit display inviting the occurrence of a special prize is made (S115). Thereafter, a special prize advantageous to the player is generated (S116). The lottery execution means 112
If the result of the lottery is lost (N in S114),
The result of the symbol fluctuating game is eventually lost display (S12
2) In such a case, no special prize will be generated. The above-described series of game processes is repeated until the player finishes the game (S117).

As described above, in the gaming machine 10, each time the symbol-changing game is executed, the probability that the result is a big hit display changes each time, and the probability increases or decreases, so that the game changes. Will be rich. Further, the display of the probability display device 35 allows the player to easily confirm the guideline of the jackpot display.

The probability display device 35 is the variable display device 3
Since it is adjacent to 0, the variable display device 30 and the probability display device 35 can be easily and simultaneously viewed. In addition, in the probability display device 35, if the display control is performed so that the selected probability is finally stopped after the various probabilities are exchanged and changed, the interest in the game can be further enhanced.

The flowchart shown in FIG. 8 shows a special prize generation process executed when the result of the symbol change game is a big hit display. In this process, first, the variable winning device 50 is opened (S131). More specifically, if the symbol random number selected by the lottery executing means 112 is a big hit, a special prize signal is output from the special prize generating means 116 to the variable prize device 50 based on this. Then, the solenoid 52 of the variable winning device 50 is driven to open the movable plate 51 for a predetermined time (for example, 29 seconds).

While the variable winning device 50 is open, it is determined based on a winning signal from the winning detection switch 53 whether or not a predetermined number, for example, 10 wins have been made (S13).
2). If ten prizes are won (Y in S132), the solenoid 52 is driven based on a signal from the special prize generating means 116, and the movable plate 51 is driven for a predetermined time (for example, 2 seconds)
, The variable winning device 50 is closed (S134).

If there are no 10 winnings (S
At 132, N), it is determined whether or not a timeout of 29 seconds has occurred (S133). If a timeout has occurred (Y at S133), the variable winning device 50 is closed (S134). If it is not time-out (N in S133), 10
The process returns to the determination of whether or not there is a winning.

After the variable winning device 50 is closed for 2 seconds,
Again, the variable winning device 50 is opened for 29 seconds,
Before that, it is determined whether or not the number of rounds (a period from the opening of the variable winning device 50 to the closing thereof to one closing thereof is one round) has reached a predetermined upper limit of 16 rounds (S135). ).

If the number of rounds has not yet reached the upper limit (Y in S135), it is determined whether or not a winning has been made in the V winning opening 55 (S136). Here, if no winning has been made in the V winning opening 55 (N in S136), the special prize ends at that time (S137). On the other hand, if a winning has been made in the V winning opening 55 (Y in S136), the next round is performed again and the variable winning device 5
0 is released (S131). Also, when the maximum number of rounds has been reached (N in S135), the special prize ends (S13).
7).

In the above-described embodiment, a case has been described in which the gaming machine according to the present invention is applied to a pachinko machine. However, the gaming machine is not limited to a pachinko machine, but may be applied to other similarly functioning gaming machines. It is possible. For example, the present invention can be applied to various game machines using a ball as a game medium, such as an arrangement ball machine.

The display unit 31 of the variable display device 30
Are partitioned in a matrix, but a simple configuration in which three display units are arranged in a horizontal line may be employed. Also, as the jackpot display in the symbol change game, the case where the same symbols, symbols, etc. are aligned has been described, but in addition, for example,
There are cases where symbols are arranged in a specific order, cases where symbols and figures are in a specific combination, and the like.

The game contents to be simulated in the symbol fluctuating game are not limited to the symbol matching as in the slot machine described above. For example, a card game, roulette, or various games in which a predetermined story can be expressed on a screen such as development can be simulated.

Although the winning of the ball into the starting winning opening 20 is set as a starting condition for executing the symbol fluctuating game, another indicator for performing the auxiliary fluctuating display game, an opening / closing operation, and the like. Satisfying a certain condition in a winning device or the like for playing a game may be set as the starting condition.

Although the probability display device 35 is provided integrally with the variable display device 30, they may be separated and separately arranged on the game board surface 11. Of course, the probability display device 35 may display the probability itself such as “1/400”. In addition, the special prize is set to repeatedly open and close the variable prize device up to 16 times. However, the present invention is not limited to this. For example, the ratio of the number of prize balls may be temporarily increased, or another character may be won. Various states may be set, such as changing to an easy-to-use form.
