DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case where a plurality of patterns of a plurality of symbols are arranged on an outer peripheral surface or a plurality of images of the same number of cylinders are rotated side by side, and when a specific pattern is stopped side by side The present invention relates to a symbol combination game machine such as a so-called slot machine, a pachislot, etc., which is a prize.

[0002]

2. Description of the Related Art For slot machines, various examples of symbol combination control (for example, Japanese Patent Publication No. 2-16154 and Japanese Patent Publication No. 3-72313) have been proposed. The three rotating drums rotating about the rotation center axis are arranged side by side on the left and right, and each rotating drum has 21 kinds of symbols arranged on an outer peripheral surface thereof and rotates independently of each other.

[0003] When a medal is inserted and the start lever is pulled, the three winding drums rotate, and each time a stop button provided for each of the rotating drums is pressed, the corresponding rotating drum stops appropriately.

When the three torso stops are stopped, if the combination of the symbols of each torso displayed on the display window on the winning line matches a predetermined winning combination, the number corresponding to the winning combination is determined. There is a medal payout. Here, the turning time from when the stop button is pressed until the turning actually stops,
Not constant but controlled by computer.

[0005] Therefore, even if the player presses the stop button aiming at a specific symbol, it is not always possible for the symbol to appear on the winning line, and it is avoided that the payout rate becomes extremely high in a skilled player. The payout rate is controlled so as to be substantially constant regardless of the skill level of the player.

That is, if a lottery operation is performed by a computer so that a predetermined combination of various winning symbols is selected with a certain probability for each of the winning combinations, and the lottery is won (internal winning), , So that the combination of the winning symbols appears.

[0007] That is, a kicking-out process for preventing other winning symbol combinations that have not been internally won from appearing on the winning line, and a pull-in process for drawing in internally winning symbol combinations on the winning line are performed.

[0008]

In the case of internal winning, since the kicking process and the pull-in process are performed equally for each turn drum, the order in which the stop button is pressed, that is, the order in which the three turn drums are stopped, is a prize. Does not affect the probability of doing so. Therefore, the player must press the stop button in an appropriate order without making a decision to perform the game in an advantageous manner, resulting in a monotonous game with a poor degree of technical intervention by the player.

[0009] The present invention has been made in view of such a point,
The purpose thereof is to provide a symbol combination game device having various game characteristics in which determining the order in which the symbol display means is stopped is an important factor in the game.

[0010]

In order to achieve the above object, according to the present invention, a plurality of symbol display means for arranging a plurality of types of symbols in a predetermined number and displaying them sequentially and repeatedly are arranged side by side. In a symbol combination game device in which the player repeatedly operates the stop switches provided corresponding to the means, the display is repeatedly stopped, the winning is determined by the combination of the symbols arranged on the winning line, and the payout of the medal is performed. Lottery means for performing a lottery of the determined winning symbol combination, and a plurality of symbol display means which have not been stopped yet based on the stopped state of the symbol display means which has been stopped earlier when the internal lottery means has been won. A control device for controlling the symbols so as to provide a difference in the probability of appearance of the symbols on the winning line is provided.

Since there is a difference in the probability of appearance of the internally won symbols on the winning line of the plurality of symbols displaying means to be stopped later, the symbol displaying means having a high appearance probability of the internally winning symbols on the winning line is selected. It is important to stop the game, and it is necessary for the player to play the game in accordance with the stop, and the game device can be an interesting game device having various game characteristics.

According to a second aspect of the present invention, there is provided the symbol combination game device according to the first aspect, wherein a plurality of symbol display means which have not been stopped yet correspond to the stopped state of the previously stopped symbol display means. The informing means for informing the player of the advantageous order is provided.

Since the player can advantageously develop the game and increase the possibility of winning by performing a stop operation according to the notification of the notification means, even a beginner who is not used to the game can greatly enjoy the game.

According to a third aspect of the present invention, in the symbol combination game device according to the second aspect, the notification means is displayed in advance as a part of a description. Since the advantageous order of the stop operations of the plurality of symbol display means is displayed as a part of the explanation, the player can perform an advantageous stop operation while watching the display.

According to a fourth aspect of the present invention, in the symbol combination game device according to any one of the first to third aspects, the symbol display means is configured such that a predetermined number of a plurality of types of symbols are arranged on an outer peripheral surface and are driven. It is a turning body that is rotated by means and sequentially and repeatedly displays a symbol on a display window. The symbol display means is a mechanically rotating winding drum.

When the number of inserted medals is three,
All five pay lines 8 including the pay line 8 oblique to the mark are valid. Note that the effective pay lines 9 at both ends of the activated pay line 8 are lit to inform the player of the effective pay line. By the way, on a part of the display panel 3, there is provided a notification plate 4 which describes an advantageous order of the stop operation of the rotating drum 6.

FIG. 3 is a schematic block diagram of a control system in the main drum type gaming machine 1. As shown in FIG. The game is controlled by the microcomputer 20 and controlled by the CPU 21.

The CPU 21 uses the RAM 23 according to the program written in the ROM 22 to perform signal processing, drive control,
Perform lottery work. After the stop button 13 is pressed, a table of the predetermined winning symbol combination, winning probability of each winning, the number of payouts, etc.
A large number of tables for controlling until the operation is stopped are written.

Various signals are input to the CPU 21 through the input port 24. That is, a medal insertion sensor 30 for detecting a medal inserted from the medal insertion slot 11, a start switch 3 operated by operating the start lever 12.
1, a stop switch 32 that is operated by each operation of the three stop buttons 13, a turning position detecting sensor 33 that detects a predetermined rotation position of each of the three turning drums 6 and outputs a reset signal, A signal from a medal payout sensor 34 or the like that detects a paid out medal is input to the input port 24.
Is input to the main CPU 21 via the.

On the other hand, an instruction signal is output from the CPU 21 to the motor drive circuit 35 via the output port 25, and the motor drive circuit 35 drives the three stepping motors 18 to drive the three turning drums 6 respectively. Control rotation.

It is determined how many pulses the symbol of the turning drum 6 is displayed after driving the stepping motor 18 after receiving the reset signal, and the number of pulses is counted based on the reset signal. The rotation of the body 6 is controlled.

The CPU 21 outputs a medal payout signal to the hopper drive circuit 36 through the output port 26, and the hopper 16 is driven by the hopper drive circuit 36 to pay out medals. Further, the CPU 21 outputs an instruction signal via the output port 27 to a sound drive circuit 37 for driving the speaker 17 and a display drive circuit 38 for lighting various displays 10 and the like.

The main torso gaming device 1 is controlled by the above control system, and the game proceeds. In addition, in the design,
7, BAR B, Watermelon S, Bell II, Plum P, Cherry C, JACJ, etc.
Are arbitrarily arranged.

Each symbol corresponds to a symbol number in order, and FIG. 5 shows the correspondence of each symbol 6 in a table. The winning symbol combinations include "7-7-7" and "B-
BB "," SSS "," PPP "," JJ
-J ".

The control procedure of the game progress by the CPU 21 will now be described with reference to FIG. First, a medal is inserted (Step 1), the start lever 12 is operated and the start switch is turned on (Step 2), and it is determined whether or not an internal winning state is established (Step 3).

At first, since there is no internal winning state, the process proceeds to step 4 and a lottery of a winning symbol combination is performed with a predetermined probability.
It determines whether the symbol combination of the internal winning is determined or not. Then, it is determined in step 5 whether or not an internal win has occurred. If the internal win has not occurred, the process proceeds to step 20 and the game proceeds in the escape mode. In the off mode, control is performed so as not to win.

If the internal winning has been achieved, the process proceeds to step 6 where the internal winning mode is set, and the control mode is set such that the internal winning symbols appear on the winning line, and the three winding drums 6 start rotating simultaneously. (Step 7). Then, in the next step 8, the first stop table (table for first stopping the rotating drum) for each of the three rotating drums 6 is determined by the normal selection at the time of the internal winning.

For example, FIG. 6 shows the first stop table selected for the left turning drum 6 assuming that "PPP" has now been internally won. The first line shows a symbol number appearing at the center of the display window 5 when the stop button 13 is pressed.

The second line indicates the number of symbols to be slid from when the stop button 13 is pressed until the torso 6 stops. Up to four symbols can be slid. Lines 1 and 2 above
The ROM 22 stores a table including the rows.
In FIG. 6, a symbol number which stops at the center of the display window 5 and a symbol (stop form) which appears in the display window 5 when the torso stops are added in correspondence with the above table.

Therefore, referring to FIG.
Stop button 13 when 10 appears in the center of display window 5
Is pressed, the control is performed so that four symbols are slid and stopped, so that the symbol of symbol number 6 (the symbol numbers are ascending in the direction of rotation of the torso) appears at the center of the display window 5 and stops. On the left-hand side, the stop forms are P, 停止, and J in order from the top. That is, the torso 6 stops after the appearance of P, .DELTA., J in the display window 5. FIG.

As shown in FIG. 6, even if the stop button 13 is pressed at any symbol number, the plum P is pulled in and stopped. Selected. Left turning body 6
The tables related to the normal pull-in process are selected independently of each other for the center and right turning drums 6 as well.

As described above, the table is selected for the three turning drums 6 in step 8 and when any one of the stop buttons 13 is first pressed in step 9 (the first stop button is turned on), the corresponding turning drum ( The first torso is stopped according to the table selected as described above (step 10).

Next, at step 11, the remaining 2 still rotating
The second stop table (table for stopping the second rotation cylinder) for each of the rotation cylinders 6 is determined by a special selection different from the usual one. That is, a table having a large difference in the probability that an internally won symbol appears on a winning line based on the stop state of the first torso is selected as each of the remaining two torso 6 second stop tables.

For example, assuming that "PPP" has been internally won, when the first barrel stops now (step 10),
It is assumed that the left torso is stopped with the plum P appearing in the upper stage as shown in FIG. Then, the winning lines in which the plums P may be arranged are the upper horizontal marks and the obliquely downward marks.

In order to select each of the second stop tables for the remaining two rotating center rollers and the right rotating body, the left plum P of the left rotating body appears on the upper stage in FIG.
And a second stop table as shown in FIG. 9 is selected.
FIG. 8 is a second stop table of the center turning drum, and FIG. 9 is a second stop table of the right turning drum.

As shown in FIG. 8, the central torso has a case where the plum P is drawn into the winning line of the mark, that is, the upper stage.
There is one case where the plum P is drawn in the middle line of the winning line of the mark.
There are 11 ways, and the appearance probability of the plum P that can win a prize in 11 of the 21 ways is 11/21.

On the other hand, as shown in FIG. 9, the right side of the torso controls all the 21 ways to draw the plum P into the middle stage.
Therefore, the plum P cannot appear on the mark and the winning line of the mark with the possibility of winning, and the appearance probability of the plum P with the possibility of winning is 0.

As described above, unlike the usual case, the second stop table which has a large difference in the probability that the internally won symbol appears on the winning line which may have a winning based on the stop state of the first body is specially provided. Selected.

Therefore, in the above example, if the central body is selected as the second body to be stopped, the plum P can appear on the winning line with a probability of 11/21 with a probability of 11/21. If you choose a torso, you lose the possibility of winning. Therefore, the player should see the stopped state of the left-handed rotating body stopped first and select the center rotating body as the second stopped rotating body.

Further, for example, as shown in FIG. 10, it is assumed that the left turning drum stops by causing the plum P to appear in the middle stage. Then, the only winning line where the plums P may be arranged is the winning line of the middle horizontal mark.

In such a case, the second stop tables of the remaining two central and right turning cylinders are the same as those in the above-described example shown in FIGS.
In the table shown in FIG. 8, if the central bobbin is selected as the bobbin to be stopped next, there is one case where the plum P is drawn into the winning line of the mark with reference to FIG. 8, and the appearance probability is 1/21. When the right torso is selected, referring to FIG. 9, in all cases, the plum P is drawn into the winning line of the mark, and the appearance probability is 1 and the plum P always appears in the middle row. Therefore, the player should select the right hand torso as the second to stop.

Therefore, the notification board 4 provided on the display panel 3 describes an advantageous order for stopping the torso, and the player can win a prize by stopping the torso according to the described order. It is possible to enhance the character, and even beginners who are not accustomed to the game can greatly enjoy the game.

When the player selects the torso to be stopped in this way and presses the second stop button (step 12), and stops the second torso (step 13), the remaining one still rotating in the step 14 The third stop table is selected for the torso in the usual way. That is, similarly to the selection of the first stop table in the step 8, the table related to the normal pull-in process when the internal winning is performed is selected.

When the third stop button is pressed in step 15, the third cylinder stops based on the table (step 16), and all three cylinders 6 stop. Next Step 17
Then, it is determined whether or not the internally won symbol combination is actually lined up on the winning line, and if it is, the internal winning mode is canceled (step 18), and the payout medal is paid out. (Step 19) If it is not true, the program skips Steps 18 and 19 and returns to Step 1.

As described above, it is important to select and stop the symbol display means having a high probability of appearance of the internally won symbol on the winning line for the two torso to be stopped second, and it is important for winning to play. It is necessary for the player to play in response to this, and it is possible to interest the player with various game characteristics.

In the above-described embodiment, the advantageous order for stopping the rotating drum is described on the notification plate 4. However, a lamp is arranged in correspondence with each rotating drum, and the lamp for stopping the rotating drum secondly. The torso may be displayed by lighting a lamp or the like. In some cases, a player may know an advantageous order for stopping the torso without using the notification means, and the notification means is not always necessary, but is disadvantageous for an unskilled player.

The symbol display means of the symbol combination game machine 1 is a mechanical device for rotating the torso 6 by a motor, but is displayed on a CRT display or a liquid crystal display which simulates the rotation of the torso. You may make it.
