Description

The present invention relates to a gaming machine including a display unit and capable of giving a privilege to a player.

In a pachinko machine, an arrangement ball machine, or the like as a gaming machine, when a game ball wins a start opening, a symbol variation using a symbol group composed of two or more symbols (hereinafter referred to as “symbol variation”).
) On the LCD.
After the change is started, a combination of symbols that partially stops the change (for example, the left symbol and the right symbol) may become a reach symbol (for example, a slotted symbol).
In this case, a still image or a moving image (animation or the like) is displayed as a reach, or the change speed is changed for the remaining fluctuations.
Furthermore, when the combination of symbols that finally stops changing becomes a jackpot symbol, a jackpot game or the like is performed as a jackpot to give a bonus to the player.

However, the only symbol variation performed in a conventional gaming machine is the variation in which two or more symbols constituting the symbol group are sequentially displayed.
As described above, since there is only one pattern variation mode, the player gradually gets used to the variation display and gets bored.
The present invention has been made in view of these points, and an object of the present invention is to provide a gaming machine capable of maintaining the enjoyment of viewing the display unit by increasing the pattern variation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[Embodiment 1] Embodiment 1 is an example in which the present invention is applied to a pachinko machine as a gaming machine to switch between the first symbol variation and the second symbol variation before and after reach.
The first embodiment will be described with reference to FIGS.

First, on the game board 12 of the pachinko machine 10 shown in FIG. 2, a gate 32 having a gate sensor 58 for detecting a pachinko ball passing therethrough, passage ports 24 and 62 through which the pachinko ball can pass, and a winning pachinko ball are detected. A composite device having a start opening 30 having a start opening sensor 60, a large winning opening 34 having an open / close lid 74 that can be opened and closed by a solenoid 54, a special symbol display 22, and holding ball lamps 20 and 28, as will be described later. 14. In addition, a general prize opening, a windmill, an obstacle nail, etc. are appropriately arranged.

Below the game board 12, there are an operation button 48 (operation unit) for giving instructions to the pachinko machine 10, an ashtray 46 for inserting cigarette butts, etc., and a lower plate 44 for temporarily storing pachinko balls including prize balls. A handle 40 provided with a touch sensor 42 for detecting whether or not the player 2 is touching, and a sound (including sound, sound effects, music, etc.) provided inside an upper plate 38 which is a receiving tray for prize balls.
) And the like.
In addition, a frame opening sensor 36 that detects the opening of the glass frame 18 (gold frame), and lamps 16 (light emitters) arranged at appropriate positions according to the game content of the pachinko machine 10 and the like are provided.
Further, a ball lending switch 64 for instructing ball lending, a return switch 72 for instructing to return a prepaid card, and the like are provided above the upper plate 38.

By the way, the passage 24 provided in the game board 12 is provided with a normal symbol display 26 capable of displaying a normal symbol.
The normal symbol display 26 has one or more light emitters (for example, LEDs that emit green, red, etc.), starts to change when the pachinko ball passes through the gate 32, and stops when a required period (for example, 10 seconds) elapses.
For example, when a normal symbol is in a specific display mode (specifically, a state where a specific LED is lit in red) due to blinking of a light emitter or the like, the lid of the lower start port 68 is closed for a certain period (specifically, 4 Open for a second).
In addition to the opening / closing lid 74 described above, the special winning opening 34 is a special area in which the big hit gaming state can be continued within the required number of times (for example, 16 times) when the pachinko ball wins within the large winning opening opening period (for example, 20 seconds). V zone 56, and a normal area where only award balls are paid out.
In order to detect pachinko balls, a V zone sensor 52 is provided in the V zone 56, and a winning sensor 70 is provided in the normal region.
In addition, a lower start port 68 (a function equivalent to the start port 30) provided with a start port sensor 66 for detecting a winning pachinko ball is provided below the big winning port 34.
Both the start opening 30 and the lower start opening 68 pay out a prize ball in the same manner as a normal winning opening when a pachinko ball wins.

3A is a partially enlarged view of FIG. 2 which shows a special symbol display 22 capable of displaying special symbols, and the number of pachinko balls that have passed through the gate 32 during normal symbol variation. The hold ball lamp 20 to be displayed, the hold ball lamp 28 to display the number of pachinko balls (that is, hold balls) won in the start opening 30 and the lower start opening 68 during the change of the special symbol, and the top winning opening 76 as a normal winning opening (So-called top hole).
Here, the number of pachinko balls that can be recognized by the display of the holding ball lamp 28 is referred to as “the number of holding balls”.
Each of the holding ball lamps 20 and 28 includes one or more light emitters (for example, four LEDs).

For example, a liquid crystal display is used for the special symbol display 22 to display a special symbol (lottery display symbol), a background symbol (decorative symbol), or the like including symbols such as characters, symbols, codes, figures, and images.
The special symbol display 22 is configured so that one or more display units 8 can be displayed simultaneously or non-simultaneously, and the displayed symbol becomes a jackpot symbol (predetermined display mode; for example, a special symbol combination “777”). It is configured to give a privilege that is a game condition advantageous to the player 2 such as a big hit game.
As for the display (variation and stop) of symbols, a group of symbols arranged in a line as shown in the example shown in FIG. 3B is sequentially arranged in a predetermined direction (for example, the vertical direction or the horizontal direction of the special symbol display 22). 3C and 3D show the first symbol variation to be displayed and the number of symbols to be displayed almost simultaneously after the aggregate 78 composed of two or more symbols as shown in FIG. 3A is displayed. , The second symbol variation to be changed like the aggregates 86, 88 and 89 shown in FIG.
For the sake of simplicity, an example in which almost the entire screen of the special symbol display 22 is used as the display unit 8 will be described below.
In addition, the symbol or symbol group displayed on the special symbol indicator 22 is composed of ten special symbols (single symbols) composed of the same combination of numbers as shown in FIG. The left symbol group 80, the middle symbol group 82, the right symbol group 84, etc., which are divided into different colors, are used.

Next, the main control board 100 for realizing the pachinko game by the pachinko machine 10 and a special symbol display upon receiving a display command (for example, a signal including a pattern or a display pattern at the time of fluctuation stoppage) sent from the main control board 100 The display control board 200 that displays a symbol on the container 22 will be described with reference to FIG.
The main control board 100 and the display control board 200 are both provided on the back side of the pachinko machine 10, for example.

The main control board 100 corresponding to the game control unit 4 is configured around a CPU (processor) 110.
The main control board 100 is a ROM 112 that stores a game control program, required data (for example, jackpot value, etc.), data (for example, a lighting pattern, a sound pattern, a vibration pattern, an operation pattern, etc.) necessary for realizing an effect. RAM 114 for storing data such as various random numbers and signals, input processing circuit 102 that receives signals sent from various input devices and converts them into a data format that can be processed in the main control board 100, and an operation sent from the CPU 110 In response to the data, the output processing circuit 104 that activates various output devices (for example, the solenoid 54) and the display data sent from the CPU 110 receive the display of the light emitter (including lighting).
) And a communication control circuit 116 for sending necessary signals to the display control board 200, the frame control board 300, and the like.
All of these components couple to each other on bus 118.

The CPU 110 executes a game control program stored in the ROM 112 to realize a game by the pachinko machine 10, and the game control program also includes a program for realizing a procedure such as a start port process described later.
An EPROM is used for the ROM 112 and an SRAM is used for the RAM 114, but other types of memories (EEPROM, DRAM, flash memory, etc.) may be used arbitrarily.
Examples of the input device for which the input processing circuit 102 receives a detection signal and the like include start-up sensors 60 and 66, a gate sensor 58, a winning sensor (V zone sensor 52, etc.), an operation button 48, and other sensors (frame opening sensor 36). , Touch sensor 42, etc.).
The output device from which the output processing circuit 104 outputs a signal corresponds to, for example, the solenoid 54 or the like.
Examples of the light emitters that are controlled by the display control circuit 106 include the lamps 16, the holding ball lamps 20 and 28, and the normal symbol display 26.
The communication control circuit 116 can transmit required data to a hall computer or the like as necessary.

Next, the display control board 200 corresponding to the display control unit 6 is configured with the CPU 210 as a center, and a display control program and display data (for example, display information corresponding to a display command, a display pattern including a change or stop of a symbol, etc.) ROM 202 for storing data), RAM 204 for storing data such as display commands and display information and input / output signals, communication control circuit 206 for receiving data sent from the main control board 100 and sending it to the CPU 210, RAM 204, etc. Character generator 212 which stores (records) a symbol in advance and generates a display command or the like, VDP (Video Display Processor) which receives the display information sent from CPU 210 and displays the processed symbol on special symbol display 22 214 and the like.
All of these components couple to each other on bus 208.
The ROM 202 and the character generator 212 correspond to the symbol group recording means 6c in that one or more symbol groups can be stored (recorded).

The CPU 210 executes the display control program stored in the ROM 202 and displays the symbols on the special symbol display 22.
An EPROM is used for the ROM 202 and a DRAM is used for the RAM 204, but other types of memory may be used.
The communication control circuit 206 can transmit necessary data to a hall computer or the like as necessary.
The symbol data generated by the character generator 212 includes, for example, characters (alphanumeric characters, kanji characters, etc.), symbols (lottery display symbols, ornamental symbols, etc.), still images, moving images (animations, etc.), videos, and the like.
The VDP 214 having a VRAM, a palette RAM, etc. receives the display information, reads the design data generated by the character generator 212, performs image editing such as coloration designation and sprite processing, and develops the design data in the VRAM and palette RAM. Finally, the video signal, the synchronization signal, etc. are output to the special symbol display 22.
With the sprite function realized by executing the sprite processing, it is possible to easily switch between two or more symbol variations and display based on the switched symbol variations.

It should be noted that the frame control board (prize ball control board) 300 that receives the command signal sent from the main control board 100 and controls the operation of various devices, the other board, and the like are not specifically related to the gist of the present invention. The illustration and description of a typical configuration are omitted.
Examples of the various devices include a launching device that launches pachinko balls when the handle 40 is operated, and a payout device that pays out pachinko balls for lending or winning balls.

In the pachinko machine 10 configured as described above, a procedure performed by the main control board 100 in order to realize the present invention will be described with reference to FIGS.
Here, FIG. 5 shows a procedure for starting port processing that realizes a pachinko ball winning determination with respect to the starting port 30, and FIG. 6 shows a change stop that realizes symbol display by switching between the first symbol variation and the second symbol variation. Each processing procedure is shown in a flowchart.
The start port process is realized by the CPU 110 executing the game control program stored in the ROM 112 of the main control board 100 shown in FIG. 4 at an appropriate timing, and the change stop process is stored in the ROM 202 of the display control board 200. The display control program is executed by the CPU 210 at an appropriate timing.
In order to simplify the explanation, the following restrictions are applied.
First, since the start port 30 and the lower start port 68 function in the same manner, the start port 30 will be described as an example.
Secondly, in the actual pachinko machine, if the pachinko ball wins the starting port 30 during the fluctuation, the next fluctuation is temporarily held up to a predetermined number (for example, four) and the holding ball lamp 28 is turned on, After completing the current fluctuation, the next and subsequent fluctuations are performed continuously within the range of the number of reserved balls.
Therefore, it is assumed that the number of balls on hold is 0 (all the balls on hold ball 28 are turned off) and one pachinko ball has won a prize at the start port 30.

In the starting port process corresponding to a procedure embodying a part of the game control unit 4 in FIG. 5, it is first determined whether or not a pachinko ball has been won at the starting port 30 [step S10].
For example, if there is a detection signal from the start port sensor 60 shown in FIGS. 2 and 4, it is determined that a prize has been won (YES), and if there is no detection signal, it is determined that no prize has been won (NO).
If a pachinko ball wins at the starting port 30 (YES), it is determined whether or not to change the symbol [step S12].
For example, the determination is made based on whether the current gaming state is changing or a jackpot game.
If the symbol is changed (NO), various random numbers are read and stored in the RAM 114, and the display pattern including the type of symbol change is determined [step S14].
For example, one or more display patterns are determined from two or more display patterns with reference to a predetermined table stored in the ROM 112 or the like based on the read symbol display random number RC, or the first symbol as the type of symbol variation. Determine fluctuations.
Note that the type of symbol variation may not be determined based on a random number or the like, but may be set to be performed with a specific symbol variation (for example, the first symbol variation) at least when the variation starts.

Here, as the various random numbers, for example, a jackpot determination random number RA for determining whether or not the jackpot is won, or a jackpot symbol (predetermined to be displayed on the special symbol display 22 when the jackpot determination random number RA is determined to be a jackpot) The jackpot symbol random number RB for specifying the symbol display mode), the symbol random number RC for specifying the display pattern from the start to the stop after the off symbol or the fluctuation corresponds.
The “display pattern” means the order of display on the special symbol display 22 including the variation pattern and reach pattern that realize the variation of the symbol. For example, two or more recording means such as the ROM 202 and the RAM 204 in FIG. Store in advance.
The configuration content, the number of patterns, and the like of the display pattern stored in the recording unit may be unchanged, or may be increased or decreased at any timing or the content may be changed.
In the case where two or more display portions 8 realize symbol variation, the variation speed, variation direction, stop timing, order, and the like may be determined separately.
Changes in symbols include normal fluctuations that simulate the rotation of the reel, forward and reverse fluctuations in a manner that swings by an arbitrary distance around a predetermined position on the screen, synchronous fluctuations that are performed by synchronizing two or more fluctuations, There are all symbol synchronization fluctuations performed by synchronizing all symbol fluctuations.
Which change is made is arbitrary, and when the display pattern is determined according to the game state or the like, the player 2 can have a sense of expectation.

Based on the various random numbers stored in step S14, the fluctuation stop process is executed in order to realize the fluctuation of the symbol from the start of the fluctuation to the special symbol display 22 including the reach display that can be performed midway [step S16. ].
This variation stop process is a procedure that embodies a part of the display control unit 6, and will be described with reference to FIG.
Note that step S44 corresponds to a process embodying a part of the fluctuation switching means 6a.

The change stop process shown in FIG. 6 is realized based on a required display command sent from the main control board 100 to the display control board 200 at least once in a timely manner.
First, a display command such as the display pattern determined in step S14 of FIG. 5 is sent to the display control board 200, and, for example, the first symbol variation is started according to the display pattern included in the display command [step S30].

After a while after starting the change, only when some symbols change is stopped and reach is reached (YES in step S40), one or both of the symbols to be increased and decreased, the number of symbols, etc. Determine [Step S42], switch the symbol variation, and continue the symbol variation according to the determination of Step S42 [Step S44].
The determination in step S42 is based on, for example, the jackpot symbol specified based on the jackpot symbol random number RB stored in step S14 of FIG. 5, the off symbol specified based on the symbol display random number RC, the lottery result of the random number, etc. Do it.
The number of symbols to be changed by increase / decrease is 10 → 3 → 2、10 → 5 → 3 → 1、10 → 3 → 5 → 1 etc. In order to finalize a symbol as a lottery result due to fluctuations, it is desirable to finally make the number of symbols one.
When increasing in the middle, the symbols once reduced by erasing or the like may be restored.
Further, the switching of the symbol variation in step S44 is not limited to switching from the first symbol variation to the second symbol variation, for example, and may be switching from the second symbol variation to the first symbol variation.
The change of the symbol variation is optional once or more.
The aggregate to be displayed first in the second symbol variation is composed of two or more symbols, and may be all symbols constituting one symbol group stored in the ROM 202 or the like.
Note that if the number of symbols constituting the aggregate to be displayed first is determined by lottery such as random numbers, it will change at random, which makes the display interesting.
Further, when the symbols constituting the aggregate to be displayed first are associated with a privilege or the like, the player 2 can have a sense of expectation.

Then, after changing the symbol variation in the above-described step S44 or performing the symbol variation at the start of the variation without reaching reach (NO in step S40), the symbol variation is stopped and the lottery is ended [step S46]. Terminate the stop process.
By executing step S46, the special symbol display 22 displays a special symbol (such as a big hit symbol or a missed symbol) as a lottery result.
The player 2 who sees the special symbol displayed in this way can know whether the current lottery is a big hit or miss.

Returning to FIG. 5, when the fluctuation stopping process in step S16 is completed, it is determined whether or not a big hit is made [step S18].
In the case of the pachinko machine 10 that is not easily affected by external noise or the like and has high reliability, it is determined whether or not the jackpot is based on the jackpot determination random number RA described above.
If it is determined that the game is a jackpot (YES), a jackpot process is executed to give the player 2 an opportunity to obtain a prize ball [step S20].
For example, the open / close lid 74 of the big prize opening 34 is opened for a certain period (specifically, 30 seconds), and the winning balls are paid out according to the number of pachinko balls won in the big prize opening 34 or the like. A big hit game like this is realized.
Since the specific procedure of the jackpot processing is well known, its description and illustration are omitted.
On the other hand, if the pachinko ball has not won in the starting port 30 in the determination in step S10 (NO), if the symbol does not change in the determination in step S12 (YES), or if it is missed in the determination in step S18. (NO), in either case, the start port process is terminated as it is.

If necessary, it may be determined whether or not the special symbol displayed on the special symbol display 22 is a big hit depending on whether or not the special symbol displayed on the special symbol display 22 matches the big hit symbol. You may perform the jackpot process of S20.
In addition, before and after the jackpot process, a probability variation process for changing an expectation (probability) to become a jackpot symbol in the next lottery or later may be executed as necessary.
In this way, it is possible to improve the expectation of the player 2 who expects a big hit from the next time.

Next, an example in which each process shown in FIGS. 5 and 6 is executed and lottery is performed on the special symbol display 22 will be described with reference to FIGS.
The display examples shown in FIG. 7 to FIG. 10 are examples of cases where jackpots are made, and illustrations and explanations of other cases where jackpots or cases where a lot of hits occur are omitted.
In addition, the stop of a pattern fluctuation | variation shows the state which stopped finally including the display pattern which performs a revariation.

First, when the pachinko ball wins the starting opening 30, as shown in FIG. 7A, the special symbol display 22 sequentially displays the symbol group in accordance with the first symbol variation 90, the middle symbol variation 92, and the right symbol variation. 94 is started {step S30 in FIG. 6}.
These left symbol variation 90, middle symbol variation 92, and right symbol variation 94 are symbol variations using the left symbol group 80, the middle symbol group 82, and the right symbol group 84 shown in the example of FIG. 3B, respectively. .
According to this arrangement order, the left symbol variation 90 appears and disappears on the special symbol display 22 in the order of the numeric symbol “7, 6, 5,...”, And the middle symbol variation 92 has the numeric symbol “3, 2, 1, ... ”Appear on the special symbol display 22 in order and disappear, and the right symbol variation 94 appears and disappears on the special symbol display 22 in the order of the numerical symbols“ 5, 6, 7,.
In this example, both change in the downward direction of the screen (in the direction of arrow D2), but the change direction of each symbol change may be arbitrary.
3 (A), 3 (C), 3 (D), and 3 (E), each of which is composed of two or more symbols using any of the symbol groups shown in FIG. 3 (B). Examples of the aggregates 78, 86, 88, and 89 are shown.

After a while, the left symbol variation 90 and the right symbol variation 94 are stopped. As shown in FIG. 7B, both the left symbol 80a of the left symbol group 80 and the right symbol 84a of the right symbol group 84 are “ 7 ”.
In this case, the symbol combination “7x7” (x means changing), and so on.
) Corresponds to one of the reach symbols {YES in step S40 in FIG. 6}, and the middle symbol variation 92 according to the first symbol variation is switched to the second symbol variation {step S44 in FIG. 6}.
Hereinafter, an example of the second symbol variation in which the number of symbols to be displayed is changed almost simultaneously after two or more symbols constituting the symbol group are displayed will be described.

Before displaying two or more symbols constituting the symbol group, first, as shown in FIG. 7C, the left symbol 80a and the right symbol 84a as the reach symbols are displayed on the screen of the special symbol indicator 22 in a certain direction (arrows). D4, D6, etc.) or in an indefinite direction, and then moved to a position where these symbols become invisible and temporarily erased.
Along with this erasure, a symbol 96 imitating a flat plate is displayed on the special symbol display 22.
In the example of FIG. 7C, the left symbol 80a and the right symbol 84a in the middle of movement are almost half erased.

When the player 2 decreases the fluctuation speed of the middle symbol variation 92 until the middle symbol 82a can follow the middle symbol 82a with the eyes, the middle symbol 82a is placed on the upper surface of the symbol 96 as shown in FIG. It is moved downward (arrow D8 direction) to a position where it can be placed.
Then, the symbol 96 is moved to the position indicated by the two-dot chain line, and the symbol variation is performed just by moving the middle symbol 82a upward.
In this moving image display, the middle symbol 82a is moved upward (in the direction of arrow D10) as shown in FIG. 8B, and finally the middle symbol 82a is moved from the special symbol indicator 22 as shown in FIG. 8C. Erase temporarily.

After temporarily erasing the middle symbol 82a, as shown in FIG. 9 (A), the assembly 78 composed of all symbols constituting the middle symbol group 82 is moved downward (arrow D8) to such a position as to be placed on the upper surface of the symbol 96. Direction).
The aggregate 78 shown in the example of FIG. 9A is divided into a plurality of stages and displayed so as to partially overlap, and is a stereoscopic display with a depth starting from the symbol “7”.
By displaying the aggregate 78 in this way, the player 2 can recognize at a glance what kind of symbol the player 2 is configured.
In accordance with the display of the aggregate 78, the above-described symbol 96 also has a three-dimensional effect using the perspective method.
Then, similar to the above-described animation of throwing the middle symbol 82a upward, as shown in FIG. 9B, the symbol variation is performed by the animation of throwing the aggregate 78 upward, and the aggregate 78 is removed from the special symbol display 22. Temporarily erase {first display mode}.
In this erasing process, the entire assembly 78 is moved upward (in the direction of the arrow D10), or a certain direction (arrows D12, D14, etc.) or indefinite direction so that a part of the symbols constituting the assembly 78 is separated. It is also possible to move the symbols so that some symbols are moved as an aggregate and other symbols are separated.
In the example of FIG. 9B, symbols “3” and “0” are moved separately and are about to be erased from the special symbol display 22.

After that, when the assembly is moved again to a position where the assembly is placed on the upper surface of the design 96, the design determined in step S42 in FIG. 6 is reduced (thinned out), and the assembly 78 is used as shown in FIG. 9B. The assembly 86 is made up of a small number of symbols.
In the example of FIG. 9B, the front row includes a symbol “7” that can constitute a jackpot symbol.
As described above, when the symbols that can constitute the jackpot symbol are displayed in the front row, the player 2 can have a sense of privilege expectation.
Further, in order to reduce the number of symbols constituting the aggregate 86 according to the determination in step S42, the aggregate 86 is shaken in a certain direction (arrow D16 direction) or indefinite direction together with the symbol 96 as shown in FIG. 9C. Depending on the moving image, the pattern changes.
Even in this shaking process, the entire assembly 86 may be temporarily erased from the special symbol display 22 or a part of the symbols constituting the assembly 86 may be erased separately.

Further, when the assembly is moved again to a position where the assembly is placed on the upper surface of the design 96, the design determined in step S42 is reduced (thinned out), and a smaller number than the assembly 86 as shown in FIG. The assembly 88 is made up of symbols.
In the example of FIG. 10A, the symbol “7” that can constitute the jackpot symbol is erased and disappears.
Also in this case, similar to the above-described assembly 86, symbol variation is performed by a moving image that shakes the assembly 88 together with the symbol 96 in a certain direction (arrow D18 direction) or indefinite direction.
After that, the number of symbols determined in step S42 does not change, but as shown in the example of FIG. 10B, symbol “6” disappears and symbol “7” that can constitute the jackpot symbol is restored. Is displayed.
The erasure timing of the symbol “6” and the restoration timing of the symbol “7” may be substantially the same or may be in tandem.
Once the lost symbol “7” is restored, the player 2 can be further enhanced in the expectation of the privilege.
Two or more symbols may be revived.
In the example of FIG. 10B, symbol variation is performed by a moving image that shakes the aggregate 89 together with the symbol 96 in a certain direction (arrow D20 direction) or indefinite direction.
In this way, the number of elements is gradually reduced from the aggregates 78, 86, 88 composed of two or more symbols, and finally one middle symbol 82a is displayed as shown in FIG. Step S46}.
At this time, a jackpot symbol “777” composed of the left symbol 80a, the middle symbol 82a, and the right symbol 84a and a notification symbol composed of the character “big jackpot” may be displayed as necessary.

In the above-described example, the number of symbols (number of elements) displayed almost simultaneously by the aggregates 78, 86, and 88 is reduced. However, the number of symbols constituting the aggregate may be increased.
In this case, in order to finally determine the symbol, for example, after increasing it, it is reduced to one symbol, or the shape (shape, color, size, background, etc.) of the symbol to be confirmed and other symbols is made different. It is necessary to display by etc.
Similarly, two or more arbitrary numbers may be displayed on the special symbol display 22.
In this way, the aggregate itself and the number of symbols constituting the aggregate change as compared with the case where the number is simply reduced, so that the player 2 who sees the special symbol display 22 can be interested.
Further, the pattern 96 is not limited to the one imitating a flat plate, but may be an imitation of another object.
For example, in the case of a symbol 96 imitating a colander, if the character symbol has a symbol 96 and a moving image or still image is displayed so that the symbol is thinned out by moving the aggregates 78, 86, and 88 back up, There is an interesting display.

Further, the player 2 displays the symbols so that the player can visually recognize the symbols only in the middle symbol variation 92 of the middle symbol group 82, but may be displayed in other speed modes.
That is, one or both of the first symbol variation and the second symbol variation may be performed at a high speed of change so that the player 2 cannot visually recognize the symbols. When the symbol is made visible, it is easy to understand the change of symbol variation.
And as a mode of making the symbol invisible, as described above, it is not limited to a mode in which the collective or the symbol is erased so as to go out of the region of the special symbol indicator 22 to make it invisible. A mode in which a specific symbol (a special symbol, a background symbol, etc.) is hidden behind the symbol indicator 22 while remaining in the area of the symbol indicator 22, a mode in which the symbol is made transparent and invisible, a special symbol indicator The aspect which erases from a specific site | part (for example, center part, a peripheral part, etc.) within 22 area | region, and makes it invisible is applicable.
Although it is arbitrary in which aspect it makes it invisible, it can give the player 2 a sense of expectation in relation to the probability of reaching, jackpot, or the like.

According to the first embodiment described above, the following effects can be obtained.
(1) A ROM 202 or the like (symbol group recording means 6c) capable of storing a left symbol group 80, a middle symbol group 82, and a right symbol group 84 each having two or more symbols.
The first symbol variation in which the symbols constituting the symbol group are sequentially displayed using the left symbol group 80, the middle symbol group 82, and the right symbol group 84 stored in the ROM 202 or the like {step S30 in FIG. 6; FIG. 7A] The second symbol variation that changes the number of symbols to be displayed almost simultaneously after displaying all symbols (two or more symbols) constituting the middle symbol group 82 {variation switching means 6a Step S44 in FIG. 6, see FIGS. 7C to 10B}.
As described above, since the second symbol variation is newly realized in addition to the first symbol variation which is also performed in the conventional gaming machine, the enjoyment of the player 2 who sees the special symbol display 22 can be maintained.
(2) After the symbol displayed on the special symbol display 22 becomes the reach symbol (part of the predetermined display mode), the first symbol variation and the second symbol variation are switched {steps S40 and S44 in FIG. ; See FIG. 7 (B) to FIG. 10 (B)}.
In this way, the player 2 who has recognized the switching between the first symbol variation and the second symbol variation knows that the reach symbol has been displayed (that is, the reach has been reached).

(3) Of the left symbol group 80, the middle symbol group 82, and the right symbol group 84 stored in the ROM 202 or the like, all symbols (two or more symbols) constituting the middle symbol group 82 are displayed and then displayed almost simultaneously. The second symbol variation is performed to change the number of symbols {pattern variation means 6b; see step S44 in FIG. 6, FIG. 7 (C) to FIG. 10 (B)}.
Such a display in an unprecedented manner can be realized, and the enjoyment of the player 2 who sees the special symbol display 22 (display unit 8) can be maintained.
The same effect can be obtained even when this is performed for the left symbol group 80 and the right symbol group 84.
(4) The symbols to be reduced in the second symbol variation are determined by lottery such as random numbers {step S42 in FIG. 6; see FIGS. 9 and 10}.
Therefore, since it becomes impossible to predict which symbols will become invisible and disappear from the special symbol display 22, the player 2 looks at the special symbol display 22 with interest.
In addition, when the symbols are increased and displayed almost simultaneously in the second symbol variation, it cannot be predicted which symbols are visible and displayed on the special symbol display 22.
Therefore, in this case as well, the player 2 looks at the special symbol display 22 with interest.
(5) When changing the number of symbols to be displayed almost simultaneously by displaying the aggregates 78, 86, 88, the symbols are displayed in an invisible manner so as to go out of the area of the special symbol display 22 The first display mode is performed {step S42 in FIG. 6; see FIG. 9B}.
Thus, it can be clearly seen that the symbols constituting the aggregate decrease when the symbols exit from the screen (area) of the special symbol display 22.
In addition, the display may be performed in a mode opposite to the first display mode, that is, in a second display mode in which the symbols are displayed so as to be visible from outside the area of the special symbol display 22. Both of the two display modes may be performed alternately.
In this way, you can see that the number of symbols that make up the aggregate increases or decreases.

(6) Since the reach is reached with the reach symbol “7 × 7”, the number of symbols constituting the aggregates 78, 86, 88 while continuing to display “7” of the middle symbol 82a that can constitute the jackpot symbol “777” ( (The number of elements) is reduced {step S42 in FIG. 6; see FIGS. 9 and 10}.
In this way, even if the number of symbols constituting the aggregate decreases, the symbols constituting the jackpot symbol remain displayed.
Therefore, the player 2 looks at the special symbol display 22 with a sense of expectation.
(7) The number of symbols was reduced and the direction of variation was changed {step S42 in FIG. 6; see FIGS. 9B to 10A}.
If the direction of change is also changed in this way, the display becomes more interesting than when the direction of change is not changed, and the player 2 who sees the special symbol display 22 is not bored.
This is the same when increasing the number of symbols to change the direction of change, or when increasing or decreasing the number of symbols and changing the shape (shape, color, size, background, etc.) of the symbol. The player 2 who sees the special symbol display 22 in an interesting display as compared with the case where the user does not let it go is not bored.
Examples of changing the form of the symbols for some or all of the symbols as the elements constituting the left symbol group 80, the middle symbol group 82, and the right symbol group 84 are as follows: Change the color that was different in odd numbers to the same color, change the second symbol with a symbol larger than the first symbol variation, change the background used for the first symbol variation and the second symbol variation, etc. To do.

[Embodiment 2] Embodiment 2 is an example in which the present invention is applied to a pachinko machine in the same manner as in Embodiment 1 to switch between the first symbol variation and the second symbol variation before and after satisfying a specific condition.
The second embodiment will be described with reference to FIGS.
The configuration and the like of the pachinko machine 10 are the same as those in the first embodiment, and the second embodiment will be described with respect to differences from the first embodiment in order to simplify the illustration and description.
Therefore, the same elements as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

The second embodiment is different from the first embodiment in that steps S32, S34, S36, and S38 are executed instead of steps S40, S42, and S44 for switching the symbol variation before and after reach in the variation stopping process shown in FIG. Is a point.
That is, when the display pattern determined in step S14 in FIG. 5 is a specific display pattern (YES in step S32), it may be a predetermined period (constant or indefinite) after the first symbol variation is started in step S30.
For example, after waiting for 10 seconds (step S34), it is determined that the first condition is satisfied, and the number of symbols to be increased or decreased, the number of symbols to be left, etc. are determined in the same manner as in step S42 (step S36). Similarly, the symbol variation is switched and continued [step S38].

An example {refer to FIG. 9 (A) to FIG. 10 (B)} in which each process shown in FIG. 5 and FIG. 6 is executed and lottery is performed on the special symbol display 22 is the same as that in the first embodiment. Is different.
That is, after the first symbol variation is started on the special symbol display 22 and a predetermined display period and a predetermined period elapses from the variation start (both YES in steps S32 and S34 in FIG. 6), whether or not the reach is present. One or more of the left symbol variation 90, the middle symbol variation 92, and the right symbol variation 94 are displayed as shown in FIGS. 9A to 10B.

According to the second embodiment described above, the following effects can be obtained.
(1) After the first condition is satisfied {YES in both steps S32 and S34 in FIG. 6}, the symbols constituting the symbol group are sequentially displayed using the left symbol group 80, the middle symbol group 82, and the right symbol group 84. The number of symbols to be displayed almost simultaneously after displaying all symbols (two or more symbols) constituting the middle symbol group 82 {step S30 in FIG. 6; see FIG. 7 (A)}. The second symbol variation to be changed was switched {step S44 in FIG. 6; see FIGS. 9A to 10B}.
As described above, since the second symbol variation is newly realized in addition to the first symbol variation which is also performed in the conventional gaming machine, the enjoyment of the player 2 who sees the special symbol display 22 can be maintained.
(2) After the first condition is satisfied {YES in both steps S32 and S34 in FIG. 6}, all symbols (two or more symbols) constituting the middle symbol group 82 are displayed and then displayed at substantially the same time. The symbol variation for changing the number was performed {design variation means 6b; see step S44 in FIG. 6, FIG. 7 (C) to FIG. 10 (B)}.
Only when the first condition is satisfied, display in an unprecedented mode can be realized, and the enjoyment of the player 2 who sees the special symbol display 22 (display unit 8) can be maintained.
The same effect can be obtained even when this is performed for the left symbol group 80 and the right symbol group 84.

(3) Since other requirements and configurations are the same as those of the first embodiment, the same effects as those of the first embodiment can be obtained.
(4) In the second embodiment, steps S32, S34, S36, and S38 are executed instead of steps S40, S42, and S44 in FIG. 6, but steps S40, S42, and S44 in FIG. , S36, S38 may be executed.
The symbol variation performed in steps S30, S38, and S44 is not limited to the example in FIG. 6, and may be any of the first symbol variation, the second symbol variation, and other symbol variations.
Even in this case, since the second symbol variation can be newly realized, the enjoyment of the player 2 who sees the special symbol display 22 can be maintained.

[Other Embodiments] In the pachinko machine 10 (game machine) described above, the structure, shape, size, arrangement, operating conditions, etc. of other parts are not limited to the above embodiment.
For example, each of the following embodiments to which the above embodiment is applied can be implemented.
(1) In each of the above embodiments, the present invention is applied to a pachinko machine.
Instead of this form, the present invention is similarly applied to other gaming machines other than pachinko machines (for example, slot machines, arrange ball machines, sparrow ball machines, video game machines, etc.) provided with the display unit 8. Can be applied.
Even in the other gaming machines, since the first symbol variation and the second symbol variation can be switched by the variation switching means, the second symbol variation is added to the first symbol variation performed in the conventional gaming machine. Can be done.
Therefore, the enjoyment of the player who sees the display unit can be maintained.

(2) In each of the above embodiments, the special symbol display 22 is applied as the display unit 8 {see FIG. 3, FIG. 7 to FIG. 10, etc.}.
Instead of (or in addition to) this form, a display or display device capable of displaying symbols other than the special symbol display 22 may be applied.
The number of display devices and display devices is one or more, and all or a part of the display area may be used as the display unit 8.
Moreover, in each said embodiment, the special symbol display 22 was equipped with the one display part 8 {refer FIG. 3, FIG. 7 ~ FIG. 10 grade | etc.}.
Instead of this form, a configuration including two or more display units 8 may be employed.
Similarly, it is good also as a structure provided with the two or more display parts 8 about the display apparatus and display apparatus which consist of one or more arbitrary numbers.
The present invention can be applied to all or part of the two or more display units 8.
Furthermore, although the liquid crystal display is used for the special symbol display 22, any display capable of displaying symbols such as a CRT, LED display, plasma display, or the like may be used.
Further, although the normal symbol display 26 and the special symbol display 22 are used separately, the same display may be used for both.
In any case, since the second symbol variation can be newly realized, the enjoyment of the player 2 looking at the display unit 8 can be maintained.

(3) In each of the above embodiments, a jackpot symbol (or jackpot determination random number RA or the like) is applied as the predetermined display mode, and a reach symbol (or symbol display random number RC or the like) is used as a part of the predetermined display mode. Applied {see step S34 in FIG. 6, step S48 in FIG. 7, FIG. 8 etc.}.
Instead of this form, symbols other than jackpot symbols and reach symbols may be applied.
For example, a single symbol or a combination of different symbols such as “6” for the left symbol 80a and “7” for the right symbol 84a is applicable.
Even in this case, the player 2 can maintain the pleasure of watching the special symbol display 22.

(4) In each of the above embodiments, the jackpot game realized by executing the jackpot process is applied as a privilege that is a game condition advantageous to the player 2 (see step S20 in FIG. 5).
Instead of (or in addition to) this form, another privilege that is a game condition advantageous to the player 2 may be applied.
For example, shortening the symbol variation period (so-called short-time), short-time number of times, changing the probability of winning big hits (so-called probability variation), changing the number of payouts associated with winning a prize, lids, blades, movable pieces, etc. Various aspects such as opening and closing, or an aspect in which two or more forms including a jackpot game are arbitrarily combined are applicable.
In this case, the player 2 can watch the special symbol display 22 and enjoy a pachinko game while expecting other benefits.

(5) In addition, the following embodiments may be realized.
(1) A configuration in which the second symbol variation is performed with respect to the variation of the decorative symbol, or a switching between the first symbol variation and the second symbol variation is performed.
The decorative symbol means an arbitrary symbol excluding a lottery display symbol (such as a special symbol or a normal symbol) used for the lottery, and is displayed on the foreground or background of the lottery symbol.
Symbol variation may be switched before and after reach or before and after satisfying the first condition, but whether or not the second condition is satisfied, such as whether the probability of reaching or the probability of hitting exceeds a predetermined value. The symbol variation may be switched by.
In this way, since the new symbol variation is also performed for the decorative symbol after the second condition is satisfied, the enjoyment of the player 2 who sees the special symbol display 22 (display unit 8) can be maintained. .
(2) When the timing for switching the symbol variation is reached, the symbol variation may be switched and another effect may be performed.
As other effects, for example, the sound (sound, sound effect, etc.) emitted from the speaker 50 is varied, the handle 40 that the player 2 touches, the vibration of the chair on which the player 2 sits, or the movable body (character This includes a configuration including rendering means for performing effects such as different operations of the body, movable piece, movable member, and the like.
In this way, the player 2 who has listened to the sound and recognized that a specific object vibrates can recognize the change of the symbol variation without looking at the special symbol display 22.

(3) The timing to switch the symbol variation is arbitrary as long as it starts after the variation starts, but even if the symbol variation is switched before and after satisfying the condition related to the probability of the privilege (for example, the probability of being a big hit is 50% or more). Good.
In this way, the player 2 who has recognized the change of the symbol variation is improved in expectation of expecting the privilege.
(4) When displaying a symbol as an aggregate on the special symbol indicator 22, it is always a symbol that constitutes a jackpot symbol (hereinafter referred to as a “hit symbol symbol”).
) May be arranged in the front row {see FIG. 9B}.
In this way, the jackpot configuration symbol becomes more conspicuous, and the player 2 can easily increase the expectation.
Further, the arrangement of the jackpot configuration symbol may be displayed by changing it from front to back and from side to side.
By doing so, the player 2 tries to determine whether or not the jackpot configuration symbol is displayed, so the degree of attention of the special symbol display 22 increases.
Further, two or more symbols constituting the aggregate may be arranged and displayed in a line, or arranged in a matrix.
In this way, the visibility of the symbols including the jackpot configuration symbol is enhanced, so that the player 2 can easily understand the presence or absence of the jackpot configuration symbol.
