Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, and more particularly, to a natural movement of symbols in a display section when conditions for generating a special prize are satisfied.

[0002]

2. Description of the Related Art Conventionally, in this type of slot machine, after a plurality of symbols respectively arranged in a plurality of symbol rows are sequentially moved and displayed at high speed on a display section provided on a front panel,
The movement display of the symbols in the symbol row is stopped, and when the symbol stop display mode is a special prize mode that is a predetermined combination of symbols, the player is allowed to play a special game.

In order for the stop display mode of the symbols to become the special prize mode, first, the lottery means provided in the electric control device such as a microcomputer performs a lottery, and the lottery result in this lottery means establishes the special prize mode. When it is decided to do so, a flag indicating that the condition for generating the special prize mode is satisfied is set. Then, when the flag of the special prize mode is set, the stop control of the symbol is performed, and after the player operates the stop switch, the special prize mode becomes a combination of symbols so that the symbols are combined. The movement display is stopped.

[0004]

However, in the above-described conventional slot machine, the lottery result of the lottery means establishes the special prize mode, and even if the special prize mode flag is set, the display is performed. The symbol row displayed on the section is the same as the symbol row at the time of the normal game.

Then, the symbols which are the prize mode in each symbol row do not always exist within the movement display variation range in the stopping process of the symbols which are moved and displayed on the image display section. Therefore, when the special prize mode flag is set and the special prize mode is to be generated, it is necessary to perform a special symbol stop control. Forcibly, without stopping the symbol at the position where it should normally be stopped. In some cases, the symbol may be stopped at the position where the special prize mode is formed. In addition, when it is determined that the operation timing of the stop switch by the player and the timing to stop the moving display of the symbols are too far apart, the stop control is performed so that the combination of the stop symbols becomes the special prize mode. There wasn't.

For this reason, when the special prize mode is generated, when the symbol is forcibly stopped at the position where the special prize mode is constituted, the movement stop process of the symbol becomes unnatural,
It gave the player a feeling of strangeness. In addition, a player unskilled in playing a slot machine may not be able to operate the stop switch at an appropriate timing and may not be able to stop the symbol at a position configured by the special prize mode, which is a disadvantage. There was a problem such as.

The present invention has been proposed in view of the problems of the above-mentioned conventional techniques, and the purpose thereof is that the movement of the symbols in the display section is natural and the game is immature. It is an object of the present invention to provide a slot machine that enables even a person to easily stop the moving display of symbols so that the combination of symbols to be stopped becomes a special prize mode.

[0008]

The present invention is to achieve the above-mentioned object, and the contents thereof will be described below with reference to the embodiments shown in the drawings. In the invention according to claim 1, the condition for generating the special prize mode is established by a lottery means (131) for performing a lottery for generating a special prize mode with a predetermined probability, and the lottery of the lottery means (131). In the case of a symbol row group used when there is not, a normal symbol row group (132) in which a winning symbol is arranged in a state where a special prize mode is difficult to occur, and a normal symbol row in which the normal symbol row group (132) is stored A group storage means (133),
Within the movement display variation range in the stopping process of the symbols to be moved and displayed on the image display unit (40), which is a symbol sequence group used when the condition for occurrence of the special prize mode is satisfied by the lottery means (131) Special symbol sequence group (134) always arranged with a winning symbol, special symbol sequence group storage means (135) storing the special symbol sequence group (134), and based on the lottery result in the lottery means (131) , The normal symbol row group (132) stored in the normal symbol row group storage means (133), and the special symbol row group storage means (13)
5) Special symbol row group stored in (134), symbol row group display switching means for selectively switching and displaying on the image display section (40)
(136) and are included.

[0009]

According to the invention of claim 1, when the player inserts a medal for use in the game and operates the start switch (80), the symbols in the symbol row group displayed on the image display section (40). Starts moving display at high speed. At this time, the lottery means (1
In 31), at a predetermined timing, for example, when the player operates the start switch (80), a lottery for generating a special prize mode with a predetermined probability is performed, and the lottery result generates the special prize mode. If it becomes, the flag of the special prize mode is set.

Here, the symbol sequence group display switching means (136) determines and switches the symbol sequence group to be displayed on the image display section (40). That is, if the condition for generating the special prize mode is not satisfied by the lottery in the lottery means (131), the normal symbol row group (132) stored in the normal symbol row group storage means (133) is selected. On the other hand, if the generation condition of the special prize mode is established by the lottery means (131) and the flag is set, the special symbol row group (134) stored in the special symbol row group storage means (135) is selected. It

The normal symbol row group (132) stored in the normal symbol row group storage means (133) is provided with a winning symbol in a state where a special prize mode is unlikely to occur. On the other hand, the special symbol sequence group (134) stored in the special symbol sequence group storage means (135) always arranges the winning symbols within the movement display variation range in the stop process of the symbols to be moved and displayed on the image display section (40). It is set up. Then, when the player operates the stop switch (90), the symbols that have been moved and displayed at high speed on the image display unit (40) are sequentially stopped.

As described above, when the condition for generating the special prize mode is not established, the normal symbol row group (1
Since the symbols of 32) are displayed in a moving manner, if the symbols are stopped sequentially, the prize mode is not formed or the normal prize mode is formed. On the other hand, when the condition for generating the special prize mode is satisfied and the flag of the special prize mode is set, the symbols of the special symbol row group (134) are moved and displayed on the image display unit (40), When the symbols are stopped sequentially, the special prize mode can be generated very naturally.

Therefore, the symbol sequence group displayed on the image display section (40) is selectively switched and used in accordance with the establishment / non-establishment of the condition for generating the special prize mode, so that the symbol movement stop process is natural. As a result, the player does not feel uncomfortable. Further, when the condition for generating the special prize mode is satisfied, since the winning symbol is always arranged within the movement display variation range in the process of stopping the symbol to be moved and displayed on the image display unit (40), the game is immature. Even an unskilled person can easily stop the moving display of the symbols so that the combination of the symbols is a special prize mode.

With reference to the block diagram shown in FIG. 2, a schematic configuration of a portion of the electric control device 130 which performs control according to the present invention will be described. The electrical control device 130 is a lottery means 13 for performing a lottery for generating a special prize mode with a predetermined probability.
1 and normal symbol sequence group storage means that stores the normal symbol sequence group 132
133, special symbol sequence group storage means 135 storing the special symbol sequence group 134, and based on the lottery result in the lottery means 131, the normal symbol sequence group 132 and the special symbol sequence group storage stored in the normal symbol sequence group storage means 133 The special symbol row group 134 stored in the means 135 and the symbol row group display switching means 136 for selectively switching and displaying on the image display section 40 are the main constituent elements.

The normal symbol sequence group 132 stored in the above-mentioned normal symbol sequence group storage means 133 is a symbol sequence group used when the condition for generating the special prize mode is not established by the lottery of the lottery means 131. . As shown in FIG. 3, the normal symbol sequence group 132 is composed of a number of symbol sequences corresponding to the symbol display positions of the image display unit 40, and is “7”, “skull”, and “ORANGE”, respectively. , "POW", "HEAR"
A predetermined number of symbols such as T ”,“ M (green) _POW ”, and“ CHERRY ”are arranged, for example, 21 symbols each. Based on this normal symbol row group 132, the image display unit 40 has 3 vertical columns.
Three symbols in the regular symbol column of the column are displayed.

In this normal symbol row group 132, four hit symbols "7" are arranged in the symbol row corresponding to the symbol display position on the left side, and the symbol corresponding to the central symbol display position. In the row, one winning symbol "7" is arranged, and in the symbol row corresponding to the symbol display position on the right side,
"7" which is one hitting pattern is arranged. Therefore, when the normal symbol row group 132 is used, no prize mode is formed or a normal prize mode is formed.

Further, the special symbol sequence group storage means 135 described above.
The special symbol row group 134 stored in is a symbol row group used when the condition for occurrence of the special prize mode is satisfied by the lottery of the lottery means 131, and the process of stopping the symbols to be moved and displayed on the image display unit 40. The winning symbol is always arranged within the movement display variation range in. This special symbol row group 134 is shown in FIG.
As shown in FIG. 5, the number of symbol columns is equal to the symbol display position of the image display unit 40, and like the normal symbol column group 132, “7”, “skull (star)”, and “ORA”, respectively.
"NGE", "POW", "HEART", "M (green) _
A predetermined number of symbols such as "POW" and "CHERRY" are arranged, for example, 21 symbols each, and this special symbol row group 134
Based on the above, the image display section 40 displays three symbols in the special symbol column of three columns.

In this special symbol row group 134, six winning symbols "7" are arranged in the symbol row corresponding to the symbol display position on the left side, and the symbol corresponding to the central symbol display position. In the row, five hit symbols “7” are arranged, and in the symbol row corresponding to the symbol display position on the right side,
Six hit symbols “7” are arranged. Further, in each symbol row, the winning symbol "7" is always arranged within the moving display variation range in the process of stopping the symbol to be moved and displayed on the image display unit 40, for example, within 5 frames.

Therefore, when the special symbol sequence group 134 is used, it is not necessary to forcibly stop the symbols in order to form the special prize mode, and within the movement display variation range in the process of stopping the symbols, it is natural. It can be stopped to hit the pattern. Further, when the condition for generating the special prize mode is satisfied, since the winning symbol is always arranged within the moving display variation range in the process of stopping the symbol to be moved and displayed on the image display unit 40, an unskilled person in the game Even in such a case, the moving display of the symbols can be easily stopped so that the combination of the stopped symbols becomes the special prize mode.

Of the control by the electric control device 130, the control of the part according to the present invention will be described. When the player operates the credit medal insertion switch 100 to insert a medal for use in the game, an effective line is determined according to the number of inserted medals, and the effective line display section 50 lights up to display the effective line. . Then, when the player operates the start switch 80, the lottery means 131 performs a lottery so that a special prize mode is generated with a predetermined probability.

Here, if the lottery result is to generate the special prize mode, the flag of the special prize mode is set. Then, the symbol row group display switching means 136 switches the symbol row group displayed on the image display unit 40 based on the lottery result of the lottery means 131. That is, if the condition for occurrence of the special prize mode is not satisfied by the lottery in the lottery means 131, the normal symbol row group 1 stored in the normal symbol row group storage means 133.
32 is selected. On the other hand, when the condition for generating the special prize mode is satisfied by the lottery in the lottery means 131 and the flag is set, the special symbol row group 134 stored in the special symbol row group storage means 135 is selected.

In the image display section 40, one of the symbol row groups 132 and 134 selected and switched by the symbol row group display switching means 136 is switched and displayed immediately after the start switch 80 is operated, and this switching is performed. The pattern is moved and displayed in the closed state. The image display unit 40 provided on the front panel 30 displays the symbol sequence group selected by the symbol sequence group display switching means 136, and in each of the vertically three symbol sequences, a plurality of symbols are sequentially displayed at high speed. It

After that, when the player operates the stop switch 90, the symbols which are moved and displayed at high speed on the image display section 40 are sequentially stopped. At this time, if the symbol row group displayed on the image display unit 40 is the normal symbol row group 132, the probability that a special prize mode is formed is extremely low, so no prize mode is formed, or the normal mode is set. The prize mode is constructed.

On the other hand, when the symbol row group displayed on the image display unit 40 is the special symbol row group 134, the special prize mode is formed very naturally based on the stop control of the symbol, and the player is Special games can be played. Note that the special game corresponds to, for example, a big bonus game including a so-called three times JAC game and a high-probability normal game, but is not limited to this. For example, one JAC game and a high-probability normal game. It may be a single bonus game or the like.

Further, the number of symbol rows is not limited to the above-mentioned three rows, and can be appropriately changed and implemented according to the content of the game. In the above embodiment, one of the symbol column groups 13 selected and switched by the symbol column group display switching means 136.
The timing at which 2,134 is displayed on the image display unit 40 has been described as immediately after the start switch 80 is operated, but the display timing is not limited to this. For example, the player operates the start switch 80 to select the lottery means. The display of the image display unit 40 may be switched after the result of the game selected by 131 is confirmed by payout of medals or the like. In this way, by switching the display after the result of the game is confirmed, the player changes the arrangement of the symbols in a state where the movement display of the symbols is stopped, so that the combination of the stopped symbols becomes the special prize mode. Since it is possible to visually confirm that the moving display of the symbols can be easily stopped, the player can play the game with peace of mind.

[0030]

Since the present invention is constituted as described above, it has the following effects. Claim 1
In the described invention, two types of symbol row groups in which the symbols are arranged so as to generate different special prize modes are stored. That is, the normal symbol sequence group stored in the normal symbol sequence group storage means is provided with a winning symbol in a state where the special prize mode is unlikely to occur, and the special symbol sequence group stored in the special symbol sequence group storage means. The symbol is always arranged in the moving display variation range in the process of stopping the symbol to be moved and displayed on the image display unit.

In the symbol row group switching means, if the condition for generating the special prize mode is not established by the lottery in the lottery means, the normal symbol row group stored in the normal symbol row group storage means is selected and the lottery means is used. When the generation condition of the special prize mode is established by the lottery and the flag is set, the special symbol sequence group stored in the special symbol sequence group storage means is selected.

On the image display portion, the symbol sequence group selected and switched by the symbol sequence group switching means is displayed. In this way, when the condition for generating the special prize mode is not satisfied,
Since the symbols in the symbol row group are usually moved and displayed in the image display unit, the probability that a special prize mode will occur is extremely low even if the symbols are sequentially stopped, and the prize mode is not formed or the normal prize mode is formed. To be done.

On the other hand, when the condition for generating the special prize mode is satisfied and the flag of the special prize mode is set, the symbols of the special symbol sequence group are moved and displayed on the image display portion,
There is always a winning symbol within the movement display variation range in the process of stopping the symbol, and it is possible to generate a special prize mode very naturally. Therefore, the process of stopping the movement of the symbols can be made extremely natural, and the player does not feel uncomfortable.

Further, when the condition for generating the special prize mode is established, the winning symbol is always arranged within the movement display variation range in the stop process of the symbol which is moved and displayed on the image display section 40, so that the game is played. Even an inexperienced player can easily stop the moving display of the symbols so that the combination of the symbols is a special prize mode.
