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 predetermined conditions are satisfied in a game in which a ball is hit on a game board. Here, the gaming machine mainly refers to a pachinko machine.

[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, a rotating drum, and the like is known, and a device provided with the variable display device is generally called a fever device.

[0003] In the fever machine, when a ball wins a start winning opening established on a game board, various symbols are scroll-displayed on the variable display device. Then, when the combination of symbols after scrolling stops becomes a big hit display,
A special prize (so-called fever) is generated, and the variable winning opening is set to open and close a predetermined number of times.

The variable display device generally includes a plurality of display units arranged in a horizontal row or a matrix, and a symbol stopped and displayed on each of the display units arranged in any one row is, for example, “1,
If they are all the same as in "1, 1", a jackpot is displayed and a special prize is generated.

More specifically, when a ball wins in the starting winning opening, a random lottery using random numbers is executed by software control based on the winning. According to the result of the lottery, it has been determined whether or not a big hit is displayed on the variable display device, that is, whether or not a special prize is generated.

[0006]

However, in the above-described conventional fever machine, the display contents of the variable display device are merely repetitions in which various symbols such as numbers are sequentially switched on the screen. It tended to lack novelty and fun. Therefore, it has been difficult to visually entertain a player expecting a special prize.

Further, it is difficult for a player to predict whether or not a big hit will occur in each scroll display, and it is only possible to know after a fact whether a big hit or a loss has occurred.
For this reason, it is impossible to know at all the probability that a jackpot will appear each time, and there is a problem that this point lacks interest.

The present invention has been made in view of the above-mentioned problems of the prior art, and can enhance the interest in displaying the variable display device, and can increase the thrill and excitement in the game. It is an object of the present invention to provide a gaming machine capable of sufficiently satisfying a player's sense of expectation and ambition by providing a scene in which the probability of occurrence can be recognized by the player.

[0009]

Means for Solving the Problems The gist of the present invention to achieve the above-mentioned object lies in the following inventions. [1] When a predetermined condition is satisfied in a game in which a ball is hit on the game board surface (11), in a gaming machine (10) in which a special prize advantageous to a player is generated, a start winning opening (20) and a variable display device (30). ), First lottery executing means (111), symbol variation executing means (113), and second lottery executing means (114).
And a prize generating means (115), wherein the starting winning port (20) is provided on the game board surface (11) in a state where a ball can win, and the variable display device (30) includes various symbols. The first lottery execution means (111) executes a random lottery based on the winning of a ball into the starting winning port (20), and displays the selected lottery on the game board surface (11). The result is classified into at least a big hit, a special hit, and a loss, and the symbol change executing means (113) is based on the lottery execution by the first lottery executing means (111), and the variable display device (30) After the various symbols are changed to be replaced, a symbol variation game in which any symbol stops in various combinations is executed, and the symbol variation game is
Depending on the lottery result, the display is divided into a jackpot display, a special display, and a loss display, and the second lottery execution means (114) performs the symbol change based on the lottery result by the first lottery execution means (111). When a special display is made in the game, a random re-lottery is performed in which the player wins at a predetermined probability recognizable by the special display, and the special prize generating means (115) executes the first lottery executing means. (11
A gaming machine that, when the lottery result according to 1) is a big hit and the re-lottery result obtained by the second lottery execution means (114) is a big hit, generates the special prize after the symbol change game is completed. (10).

[2] A plurality of types of special displays in the symbol variation game are determined, and a predetermined probability of a big win in the re-lottery by the second lottery execution means (114) is different for each type. [1] characterized by being set
A gaming machine (10) as described.

[3] When the re-lottery result by the second lottery executing means (114) is a big hit, the symbol change executing means (113) changes the result of the symbol changing game from a special display to a big hit display. The gaming machine (10) according to [1] or [2], wherein the gaming machine is changed.

[4] A variable winning device (50) is provided on the game board surface (11), and the variable winning device (50) has a movable plate (51) capable of opening and closing the winning opening. The movable plate (51) is normally maintained in a closed state, and the special prize generating means (115) opens and closes the movable plate (51) a predetermined number of times to obtain the special prize [1],
The gaming machine (10) according to [2] or [3].

Next, the operation based on the above solution will be described. According to the gaming machine (10) of the present invention, when the ball hit on the gaming board surface (11) successfully wins the starting winning opening (20), the first lottery execution means (1)
11) executes a random lottery. Based on the execution of the lottery, the variable display device (30) starts a symbol change game.

In the variable display device (30), after the various symbols are changed so as to be switched, the first lottery execution means (11)
Depending on the lottery result in 1), any symbol stops in various combinations. Such a symbol variation game is controlled by symbol variation executing means (113).

As a result of the symbol change game, when a big hit display such as the same symbol is arranged in a row is determined, a special prize is generated based on the display. Here, the jackpot display is confirmed, that is, a special prize is generated when a jackpot appears in the lottery by the first lottery execution means (111). The special prize is controlled by the special prize generating means (115).

Further, when a special display such as a special symbol appears in the symbol change game, a random re-lottery is executed by the second lottery means. In such a re-lottery, a jackpot occurs with a predetermined probability, but the player can know the predetermined probability here by looking at the special display before the re-lottery. In this way, by displaying the symbol variation game,
Since the player may be able to recognize the probability of occurrence of a special prize in advance, the thrill and excitement can be increased by increasing interest.

When the result of the re-lottery is actually a big hit, a special prize is generated in the same manner as when the result of the symbol change game is a big hit display. Further, when the re-lottery result by the second lottery execution means (114) is a big hit, the result of the symbol change game is changed from the special display to the big hit display by the control of the symbol change execution means (113). If this is done, the displayed contents will change, which is interesting.

Further, if a plurality of types of special displays in the symbol variation game are determined, and a predetermined probability of a big win in the re-lottery by the second lottery executing means (114) is different for each type. , Can make the game even more interesting. In this case, the player can, of course, look at different special displays and know in advance in advance the probability that a special prize will be generated corresponding to each display.

Further, the special prize may be in various states, such as temporarily increasing the ratio of the number of prize balls. For example, the movable plate (51) of the variable prize device (50) may be moved a predetermined number of times. By opening and closing, a winning chance with a relatively higher probability than usual can be given to the player clearly and easily.

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, the operation of the gaming machine 10 will be described. The player operates the firing device 12 to launch a ball on the game board surface 11 and play a game. First, in the flowchart shown in FIG. 7, when the hit ball has successfully won the start winning opening 20 (Y in S111), a start winning signal is output from the start winning detection switch 21 to the game control device 100. When this signal is received by the first lottery execution means 111, a random number lottery is executed (S112).

When the random number lottery is performed, the right (synonymous with the reserved ball and the symbol random number) stored in the RAM 130 of the game control device 100 is less than the limit number 4 which can be displayed on the reserved ball display device 40. If (Y in S113), the execution right of the symbol change game is newly suspended up to four times (S1).
15). The number of rights reservation at this time is the reserved ball display device 4.
The addition display is performed by turning on the hold lamp 41 (S1).
14).

On the other hand, even if the random number lottery is performed in a state where the right is held up to the limit number 4 (N in S113), the right to execute the symbol changing game is abandoned (S117). afterwards,
A predetermined number of prize balls are paid out based on a prize in the starting prize port 20, including a case where the right to execute the symbol fluctuating game is suspended (S116).

Next, in the flowchart shown in FIG. 8, when the right to execute the above-mentioned symbol change game is granted (S1).
In Y), one symbol random number stored in the RAM 130 is read (S122). At this time, the subtraction display is performed by turning off one of the hold lamps 41 of the hold ball display device 40.

According to the symbol random number which is the lottery result (S
123, S127), based on a command from the symbol variation executing means 121, a symbol variation game is started on the variable display device 30 (S124, S128, S130). If the lottery result is a big hit (Y in S123), a big win display that causes a special prize to occur in the symbol change game (S124), and thereafter, a special prize advantageous to the player is generated (S125).

If the lottery result is a special win (Y in S127), a special display is performed in the symbol variation game (S128), and then the second lottery executing means 114 executes a re-lottery (S129). In the special display, 1
One of the English characters is displayed on one of the display sections 31. If the lottery result is a special winning pattern, "J" appears. Also, “P” appears for a pattern, “A” appears for a pattern, “G” appears for a pattern, and “Z” appears for a pattern.

When "J" appears in the special display, a jackpot is hit with a 100% probability. 75% when “P” appears, and 50% when “A” appears.
%, 25% when "G" appears, and 5% when "Z" appears. The player can recognize this fact in advance by looking at the specially displayed English characters.

If the result of the lottery performed by the first lottery execution means 111 is a loss (N in S127), the result of the symbol change game is a loss display after all (S130).
Thereafter, no special prize is generated, and no re-lottery is executed. The above-described game process is repeated until the player finishes the game (S126).

The flowchart of FIG. 9 shows a re-lottery process executed when a special display is made in the symbol change game. Here, the second lottery execution means 114
Using the symbol random number tables 1 to 5 (see FIG. 6) corresponding to each special display, a re-lottery is executed to determine whether or not a jackpot is finally won (S131).

More specifically, when a special display including "J" appears in the symbol fluctuation game, a re-lottery using the symbol random number table 1 shown in FIG. 6 is executed, and as a result, the jackpot is won with a probability of 100%. Become. When a special display including “P” appears, a re-lottery using the symbol random number table 2 is executed, and as a result, a jackpot is achieved with a probability of 75%.

When a special display including "A" appears, a re-lottery using the symbol random number table 3 is executed.
As a result, a jackpot is achieved with a probability of 50%. "G"
Appears, a re-lottery using the symbol random number table 4 is executed, and as a result, a jackpot is won with a probability of 25%. Furthermore, when a special display including “Z” appears, a re-lottery using the symbol random number table 5 is executed, and as a result, a jackpot is achieved with a probability of 5%.

In any case, if the result of the re-lottery corresponds to a jackpot (Y in S132), the symbol variation executing means 1
As shown in FIG. 4 and FIG.
The screen of the variable display device 30 changes from the special display to the big hit display (S133). Thereafter, a special prize advantageous to the player is generated (S134). If the result of the re-lottery is a loss (N in S132), it is displayed on the variable display device 30 that no loss occurs, that is, no special prize is generated (S135), and the re-lottery process ends.

The flowchart shown in FIG. 10 shows a special prize when the result of the symbol change game is a big hit display. In the special prize, the variable winning device 50 is first opened (S141). More specifically, if the symbol random number drawn by the first lottery execution unit 111 is a big hit, the special prize generation unit 115 sends a variable prize device 50 based on this.
The special prize signal is output to. 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).

During the opening of the variable winning device 50, it is determined whether or not a predetermined number of winnings, for example, ten, have been won based on the count signal from the winning detecting switch 53 (S).
142). If there are ten winnings here (S14
2 and Y), the solenoid 52 is driven based on a signal from the special prize generating means 115, and the movable plate 51 is driven for a predetermined time (for example, 2).
Seconds), the variable winning device 50 is closed (S144).

If there are no 10 winnings (S
In N), it is determined whether or not a timeout of 29 seconds has occurred (S143). If a timeout has occurred (Y in S143), the variable winning device 50 is closed (S144). If it is not time-out (N in S143), 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 (the period from the opening of the variable winning device 50 to the closing thereof to one closing is one round) has reached a predetermined upper limit of 16 rounds (S145). ).

If the number of rounds has not reached the upper limit yet (Y in S145), it is determined whether or not a winning has been made in the V winning opening 55 (S146). Here, if no prize has been won in the V winning opening 55 (N in S146), the special prize ends at that time (S147). On the other hand, if a winning has been made in the V winning opening 55 (Y in S146), the next round is performed again and the variable winning device 5
0 is released (S141). Also, when the maximum number of rounds has been reached (N in S145), the special prize ends (S14).
7).

As described above, when the special display is made in the symbol variable game, the player sees the special display and knows in advance the probability that the result of the symbol variable game is finally determined to be the jackpot display. Can be. Thereby, the interest in the symbol variation game is enhanced, and the thrill and excitement can be increased throughout the game.

The gaming machine according to the present invention is not limited to the above embodiment.
