Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine provided with a variable display device for variably displaying a plurality of symbols required for a game and a control means such as a microcomputer for controlling the variable display of the variable display device. And gaming machines such as pachislot machines.

[0002]

2. Description of the Related Art For example, a slot machine having a stop button, that is, a so-called pachislot machine, is a variable machine in which a plurality of (for example, 21) mechanical rotating reels are arranged and arranged in a front display window in a variable manner. It has a display device or a variable display device that is constituted by electrical means for variably displaying symbols on a reel on a screen. In response to the player's start operation, the variation display device is driven to rotate each reel, thereby displaying the symbols in a variable manner, and after a fixed time, automatically or by the player's stop operation, the rotation of each reel is sequentially performed. Stop. At this time, when a symbol of each reel appearing in the display window has a specific combination (winning symbol), a profit is given to the player by paying out game media such as coins and medals.

In such a gaming machine, in order to achieve a prize in which coins, medals and the like are paid out, an internal lottery process (hereinafter referred to as "internal lottery") wins a winning combination (hereinafter referred to as "internal lottery"). Winning "), and the combination of symbols indicating the winning of the internally won winning combination (hereinafter referred to as" internal winning combination ") can be stopped at the activated winning line (hereinafter referred to as" effective line "). It is required that the player perform a stop operation at a timing. In other words, no matter how much the internal prize is won, a prize cannot be established if the timing of the stop operation of the player is bad. That is,
At present, the mainstream is a gaming machine that requires a skilled technique for the timing of the stop operation (a high degree of technical intervening called "gaze").

[0004] In such a gaming machine, various gaming states are provided, and a specific winning combination is provided in which, when a prize is won, the gaming state has better conditions than a normal state. For example, a special bonus prize combination (hereinafter, referred to as a “big bonus” and abbreviated to “BB”) in which a game that provides a relatively large profit to a player can be performed a predetermined number of times, or a game that provides a relatively small profit to a player For winning a predetermined number of games (hereinafter, referred to as “regular bonus” and abbreviated as “RB”).

[0005] However, the frequency of winning in such a special winning combination is low, and one medal is paid out by winning a winning combination (generally called "small winning") other than these specific winning combinations. (Hereinafter referred to as “small role game”) occupies most of the game time. Therefore, it is expected that the interest of the entire game is enhanced by enhancing the playability of the small role game.

[0006] In the conventional gaming machines, there is a game machine called "small win correction". This is because, if a small winning combination occurs frequently in a certain game section and the payout rate exceeds a certain upper limit, the lottery table with a relatively low winning probability of the small win is used, and conversely, the payout rate is constant. When the value is lower than the lower limit, a kind of feedback control is used in which the transition of the payout rate is averaged by using a lottery table in which the winning probability of the small role is relatively high.

In a so-called "table control", a reel stop control is performed using a stop table in which a reel rotation position when a player performs a stop operation and a symbol to be stopped in a display window are associated with each other. There is also a method of preparing a plurality of stop tables in advance and determining a stop table to be used by random number lottery, so that the stop mode is not monotonous even in the same winning combination and the same game state.

[0008]

However, the above-mentioned "small win correction" function is intended to manage the payout rate, and does not improve the playability of the small win game. Further, even when performing “table control” in which a plurality of stop tables are prepared and various stop modes are performed,
Because it is a post production effect function as a result of the stop operation,
It does not increase the interest of the game during the game.

An object of the present invention is to enhance the interest of the entire game by improving the playability of the small role game.

[0010]

In the circuit of FIG. 2, the random number generator 36
The sampling circuit 37 generates a random number belonging to a certain numerical range, and samples the random number at an appropriate timing after the start lever operation. Any winning combination or loss is determined based on the sampled random numbers and the probability table (FIG. 11) stored in the ROM 32. Here, that one of the winning combinations is determined by the random number lottery is referred to as “internal winning”, and the winning combination is referred to as “internal winning combination”. In the present embodiment, as the probability table, the “normal probability table” and a winning probability of a predetermined winning combination (“4 cherries” in the example shown in FIG. 13) are increased as compared with the normal probability table. Table ”, and one of the probability tables is selected by lottery using random numbers sampled separately from the above random numbers.

After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. Reel 3
Reset pulses are obtained from L, 3C, and 3R for each rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. With the reset pulse thus obtained, the count value of the drive pulse counted in the RAM 33 is cleared to “0”. Thereby, RAM3
3 stores a count value corresponding to the rotation position within the range of one rotation for each of the reels 3L, 3C, 3R.

The reels 3L, 3C, 3R thus obtained
A symbol table is stored in the ROM 32 as data for associating the rotational position of the symbol with the symbol position on the outer peripheral surface of the reel. In this symbol table, the rotational position at which the reset pulse is generated is used as a reference, and
As shown in the figure, the code numbers sequentially assigned to the reels 3L, 3C, 3R at a constant rotation pitch are associated with the symbol codes indicating the symbols provided corresponding to the respective code numbers. .

Further, in the ROM 32, a winning symbol combination table is stored. In the winning symbol combination table, a winning symbol combination, a winning medal payout number, and a winning determination code representing the winning are associated with each other.

The above-mentioned winning symbol combination table is referred to at the time of stop control of each of the three reels 3L, 3C, 3R and at the time of confirming a winning after stopping all the reels.

After the lottery process based on the random number sampling (probability lottery process described later), the CPU 31 sends a stop signal sent from the reel stop signal circuit 46 at the timing of operation of the stop buttons 7L, 7C, 7R by the player. , A stop control signal for stopping and controlling the reels 3L, 3C, 3R is sent to the motor drive circuit 39. Then, the motor drive circuit 39 controls stop of the stepping motors 49L, 49C, 49R according to the stop control signal.

In the stop control of the reels 3L, 3C, 3R, when the CPU 31 receives the stop signal from the reel stop signal circuit 46, the CPU 31 sets the code number of the symbol on the center line 8c as a stop operation position in a predetermined area of the RAM 33. Writing, referring to a stop table as shown in FIG. 14 described later, the code number of the symbol corresponding to the stop operation position is written in a predetermined area of the RAM 33 as the symbol stop position, and the code number as the symbol stop position is added. The symbol is determined as a symbol to be stopped and displayed on the center line 8c when the reel stops. Based on the determined symbol stop position, the CPU 31 controls the motor drive circuit 39 to stop the reels 3L, 3C, 3R.

When the CPU 31 determines that the combination of symbols stopped on the activated line indicates a winning, the CPU 31 supplies a payout command signal to the hopper drive circuit 41 and pays out a predetermined number of medals from the hopper 40. At that time, the medal detection unit 40S counts the number of medals paid out from the hopper 40, and when the counted value reaches the designated number, the payout completion signal circuit 51 outputs a payout completion signal to the CPU.
31 is input. Accordingly, the CPU 31 stops driving the hopper 40 via the hopper driving circuit 41,
The medal payout process ends.

As described above, the CPU 31 determines a winning combination by a random number selection, and determines each of the reels 3L, 3L on the basis of the result of the lottery by the winning combination lottery and the stop signal.

Specifically, an initialization process for erasing the contents stored in the RAM 33 (RAM clear), an initialization process for communication data, and the like are performed. Subsequently, an initialization process for erasing the contents stored in the RAM 33 at the end of the game is performed (ST2). Specifically, data in the writable area of the RAM 33 used for the previous game is erased, parameters necessary for the next game are written in the writing area of the RAM 33, the start address of the sequence program of the next game is specified, and the like. I do.

Next, the CPU 31 determines whether or not there is a request for automatic insertion of medals, that is, whether or not a replay has been won in the previous game (ST3). This determination is "YE
S ", the medals for the insertion request are automatically inserted (ST
4) The process proceeds to ST6. When the determination in ST3 is “NO”, the inserted medal sensor 22S or the BET switch 1
It is determined whether or not there is an input from 1, 12, 13 (S
T5). If this determination is "YES", the process proceeds to ST6, and if "NO", the process proceeds to ST3.

Next, the CPU 31 determines whether or not there is an input from the start switch 6S based on the operation of the start lever 6 (ST6). If the determination is "YES", a process of transmitting a "start command" to the sub control circuit 72 is performed (ST7).

Next, the CPU 31 determines whether or not 4.1 seconds have elapsed since the start of the previous game (ST31).
8) If the determination is “YES”, the process proceeds to ST10, and if “NO”, the process proceeds to ST9. In the process of ST9, "game start waiting time digestion process" is performed. In the "game start waiting time digestion process", a process of invalidating an input based on an operation of starting a game by a player is performed until 4.1 seconds have elapsed since the previous game started.

Next, the CPU 31 sets a one-game monitoring timer (ST10). The one game monitoring timer includes an automatic stop timer for automatically stopping the reels 3L, 3C, 3R without depending on the player's stop operation of the stop buttons 7L, 7C, 7R.

Next, the process proceeds to ST11 in FIG.
31 performs “probability lottery processing” of performing various lotteries based on random number extraction, which is a function as a first lottery means and a second lottery means. In this probability lottery process, a lottery of a winning combination executed by the CPU 31 as the first lottery means ("winning lottery process" described later), and a CP as the second lottery means
Lottery of the probability table referred to in the lottery of the winning combination executed in U31 (“probability table lottery processing” described later) and lottery of the stop table referred to when determining the stop symbol (“stop table lottery processing” described later) I do. The details will be described later with reference to the flowchart in FIG.

Next, the CPU 31 controls the reels 3L, 3C,
3R rotation processing is performed (ST12).

Next, the CPU 31 releases the stop buttons 7L, 7
It is determined whether C and 7R are on, that is, whether there is an input from the reel stop signal circuit 46 (ST13). If the determination is "YES", the process proceeds to ST15. "N
If "O", it is determined whether or not the automatic stop timer is "0" (ST14), and if this determination is "YES", S is determined.
The process proceeds to T15, and if “NO”, the process proceeds to ST13.

Next, the CPU 31 determines the reels 3L, 3L based on the stop table set in the probability lottery process.
A "symbol stop position determination process" for determining the stop positions of C and 3R is performed (ST15). The details of the symbol stop position determination processing will be described later with reference to FIG.

Next, the CPU 31 sets the reels 3L, 3C,
3R stop processing is performed (ST16). Subsequently, it is determined whether or not all the reels have stopped (ST17). If the determination is "YES", the process proceeds to ST18 in FIG.
If “NO”, the process moves to ST13.

In the process of ST18 in FIG. 7, the CPU 31 performs a winning search. The winning search is a display window 4L, 4C, 4
This is to set a winning combination flag for identifying a winning combination based on the stop mode of the symbol in R. In particular,
The winning combination is identified based on the code numbers of the symbols arranged along the center line 8c and the winning determination table.

Next, the CPU 31 determines whether or not the winning flag is normal (ST19). This determination is "N
If "O", an illegal error is displayed (ST2).
0). If the determination in ST19 is “YES”, credits or payout of medals is performed according to the gaming state (ST19).
21).

Next, the CPU 31 sets the BB game state or R
It is determined whether or not the game is in the B game state (ST22). If this determination is "YES", "game number check processing" of BB or RB is performed (ST23). In the case of the BB gaming state, in this “game number check process”, the number of times the RB gaming state has occurred, the number of games in the BB general gaming state,
The number of winnings in the gaming state and the number of games in the RB gaming state are checked. In the case of the RB gaming state, the number-of-games check process includes the number of winnings in the RB gaming state,
And the number of games in the RB gaming state.

Next, the CPU 31 sets the BB game state or R
It is determined whether or not the end of the B game state (ST2).
4). Specifically, in the BB game state, the third R
In the B game state, the number of winnings is 8 or the number of games is 1.
It is determined whether the number of games is two or whether the number of games is 30 in the BB regular game state. If it is an RB gaming state other than the BB gaming state, it is determined whether the number of winnings is eight or the number of games is twelve. When the determination in ST24 is "YES", the CPU 31 performs an initialization process (RAM clear) for erasing the storage contents of the RAM 33 at the end of the BB gaming state or the RB gaming state (ST25).

FIG. 8 shows the procedure of the "probability lottery process" described above. This probability lottery process is performed in ST11 (FIG. 6) in the above main flowchart.

First, the CPU 31 performs a "probability table lottery process" (ST31). In the probability table lottery process, a probability table to be referred to in the next winning combination lottery process is determined by random number lottery.

Next, the CPU 31 refers to the probability table determined in the probability table lottery process, and performs a "prize role lottery process" in which any winning combination is determined by random number lottery (ST32).

Next, based on the winning combination determined in the winning combination lottery process, the CPU 31 performs a "stop table lottery process" in which a stop table referred to in the symbol stop position determination process is determined by random number lottery (ST33). ).

FIG. 9 shows the "probability table lottery process" described above.
The procedure will be described.

First, the CPU 31 extracts a random value used in the probability table lottery process in the range of 0 to 16383, and sets the random value as X in a predetermined area of the RAM 33 (ST41).

Next, the CPU 31 refers to the “probability table lottery table” stored in the ROM 32 and
The lottery value corresponding to the set values of ~ 6 is set as D in a predetermined area of the RAM 33 (ST42).

FIG. 10 shows a "probability table lottery table".
Is shown. As shown in FIG. 10, different values are set for the lottery values corresponding to the set values of 1 to 6, respectively, and this set value is set by, for example, an administrator of a gaming machine such as a clerk of a game store. Can be changed. Therefore, the above ST4
In the process of 2, when the set value is “1”, “600” is selected as the lottery value D from the probability table lottery table,
When the set value is “2”, “605” is selected as the lottery value D from the probability table lottery table, and the set value is “3”.
In the case of, "610" is selected as the lottery value D from the probability table lottery table, and when the set value is "4", "620" is selected as the lottery value D from the probability table lottery table, and the set value is "5". In the case of, “750” is selected as the lottery value D from the probability table lottery table, and when the set value is “6”, “80” is selected from the probability table lottery table.
"0" is selected as the lottery value D.

Referring again to the flowchart of FIG.
U31 determines whether the value (X-D) obtained by subtracting the lottery value D from the random number X set in the predetermined area of the RAM 33 is negative (ST43). Here, when “NO”, that is, when the value obtained by subtracting the lottery value D from the random number value X is positive (0 or more), the “normal probability table” corresponding to the set value is stored in the RA.
It is set in a predetermined area of M33 (ST44).

On the other hand, when "YES" in ST43, that is, when the value obtained by subtracting the lottery value D from the random number value X is negative, C
The PU 31 sets an “increase probability table” corresponding to the set value in a predetermined area of the RAM 33 (ST45), and subsequently performs a process of transmitting a probability table lottery winning command to the sub control circuit 72 (ST46).

Here, "YES" in the determination of ST43.
Is a "probability table lottery winning" and the above ST4
The case of “NO” in the judgment of 3 is “probability table lottery loss”.

FIG. 11 shows an example of the normal probability table and the increase probability table. Here, the normal probability table and the increase probability table selected when the set value is “3” are shown. As shown in FIG. 11, the lottery value of the winning combination “4 cherries” is set higher in the increase probability table than in the normal probability table. That is,
In the increase probability table, the winning probability for the winning combination “4 cherries” is set high.

FIG. 12 shows the procedure of the above-mentioned "winning lottery process".

First, the CPU 31 extracts a random value used in the winning combination lottery process in a range of 0 to 16383, and sets the random value as Y in a predetermined area of the RAM 33 (ST51).

Next, the CPU 31 refers to the “probability table” set in the RAM 33 in ST44 or ST45 of the probability table lottery process, and determines the lottery value of the winning number “1” in the first row of the probability table. RAM as E
33 is set in a predetermined area (ST52). For example, in the probability table lottery process, the RAM 33
Is set in the predetermined area of the RAM 33 as E, the lottery value “200” of the winning number “1” is set.

Next, the CPU 31 determines whether the value (YE) obtained by subtracting the lottery value E from the random number Y set in a predetermined area of the RAM 33 is negative (ST53). Here, when "YES", that is, the random number value Y is used to select the lottery value E
When the value obtained by subtracting is negative, the CPU 31 determines a winning combination corresponding to the winning number as an internal winning combination with reference to a probability table as shown in FIG. 11 (ST54), and proceeds to the process of ST59.

On the other hand, if “NO” in ST53, that is, if the value obtained by subtracting the lottery value E from the random number Y is positive (0 or more), the CPU 31 adds “1” to the winning number (ST53).
55) It is determined whether or not the winning number after the addition is "7" or less (ST56). If “YES” here, CP
U31 refers to the probability table, sets the lottery value corresponding to the winning number after the addition as E in a predetermined area of the RAM 33 (ST57), and proceeds to the process of ST53.

If "NO" in ST56, CPU 31
Decides “losing” as an internal winning combination (ST5
8). Then, a process of transmitting the internal winning combination command to the sub control circuit 72 is performed (ST59).

FIG. 13 shows the procedure of the above-mentioned "stop table lottery process".

First, the CPU 31 determines whether or not the internal winning combination determined in the above-described winning combination lottery process is “4 cherry” (ST61). If "NO" here, that is, if the internal winning combination determined in the above-mentioned winning combination lottery process (FIG. 12) is other than "4 cherry", the CPU 31 stores the stop table corresponding to the internal winning combination in the RAM 33. It is set in a predetermined area (ST62). The stop table includes a code number of a symbol on the center line 8c when the player performs a stop operation (hereinafter, referred to as a “stop operation position”) and a code number of a symbol to be stopped and displayed on the center line 8c (hereinafter, a “symbol stop position”). This stop table is set with a plurality of types of stop tables corresponding to the types of winning combinations for each of the three reels.

On the other hand, if “YES” in ST61, that is, if the internal winning combination determined in the above-mentioned winning combination lottery process (FIG. 12) is “4 cherries”, the CPU 31 subsequently proceeds to the stop table lottery process. Is extracted in the range of 0 to 16383, and the random number is set as Z in a predetermined area of the RAM 33 (ST63).

Next, the CPU 31 refers to the “stop table lottery table” stored in the ROM 32 and
The lottery value corresponding to the set values of ~ 6 is set as F in a predetermined area of the RAM 33 (ST64).

FIG. 14 shows a "stop table lottery table".
Is shown. The set values of 1 to 6 are the same as those of the above probability table lottery table. Therefore, in the process of ST64, when the set value is “1”, “700” is selected as the lottery value F from the stop table lottery table, and when the set value is “2”, “8” is selected from the stop table lottery table.
"00" is selected as the lottery value F. When the set value is "3", "900" is selected as the lottery value F from the stop table lottery table, and when the set value is "4", "900" is selected from the stop table lottery table. "1000" is selected as the lottery value F. When the set value is "5", "1200" is selected as the lottery value F from the stop table lottery table, and when the set value is "6", "1200" is selected from the stop table lottery table. 16
00 ”is selected as the lottery value F.

Referring again to the flowchart of FIG.
The PU 31 determines whether the value (Z-F) obtained by subtracting the lottery value F from the random number Z set in a predetermined area of the RAM 33 is negative (ST65). Here, when “NO”, that is, the value obtained by subtracting the lottery value F from the random value Z is positive (0 or more)
In the case of, the stop table of "normal setting" is set in a predetermined area of the RAM 33 (ST66).

On the other hand, when "YES" in ST65, that is, when the value obtained by subtracting the lottery value F from the random value Z is negative, C
The PU 31 sets a stop table of “setting for easily pulling in four cherries” in a predetermined area of the RAM 33 (ST
67) Subsequently, a process of transmitting a stop table lottery winning command to the sub control circuit 72 is performed (ST68).

Here, "YES" in the determination of ST65.
Is a "stop table lottery winning" and the above ST6
The case of “NO” in the determination of 5 is “stop table lottery loss”.

FIG. 15 shows an example of the stop table. Here, the stop table referred to when the stopped reel is the left reel 4L and the internal winning combination is "4 cherry" is shown. .

Further, FIG. 15 (1) shows a symbol “Cherry (a symbol 9 in FIG.
7) shows a "normal setting" stop table in which stop display is set to be able to be stopped and displayed in the upper or lower row of the left display window 4L.

When the "normal setting" stop table is set and the stop operation position is one of 3, 4, 14, and 15, the symbol "JAC" of 3 or 14 is the symbol stop position. Then, "Cherry" is stopped and displayed at the lower stage of the left display window 4L, and "Small winning combination of four cherries" is won. When the stop operation position is any one of 5, 6, 16, and 17, the symbol “orange” of 5 or 16 is the symbol stop position, and thus “cherry” is stopped and displayed in the upper part of the left display window 4L. "4 Cherry Small Role" wins.

FIG. 15 (2) shows a symbol “Cherry”, which is a prize for “Small role of four cherry”, in the left display window 4L.
9 shows a stop table of “setting for easily pulling in four cherries” set so that stop display is easy in the upper or lower row of FIG.

When the stop table of "setting for easily pulling in four cherries" is set, when the stop operation position is any of 3, 4, 14, and 15, 3 or 14
Is set to the symbol stop position, "Cherry" is stopped and displayed at the lower stage of the left display window 4L, and a winning combination of "4 cherry small wins" is won. Further, when the stop operation position is 5 to 9
Or in any of 16 to 18, the symbol "orange" of 5 or 16 is the symbol stop position, so the left display window 4L
"Cherry" is stopped and displayed in the upper row, and "4 Cherry small role" is won. As described above, in the stop table of “setting for easily pulling in four cherries”, the left display window 4L
The stop operation position at which "Cherry" is stopped and displayed in the upper row is set widely. In other words, the possibility of winning of the "small winning combination of four cherries" is increased.

FIG. 16 shows the procedure of the above-mentioned "symbol stop position determination processing". This symbol stop position determination processing is performed in ST15 (FIG. 6) in the above main flowchart.

First, in step ST62, ST66 or ST67 of the above-mentioned stop table lottery processing, the CPU 31
Reference is made to the stop table set in the third predetermined area (ST71).

Next, the CPU 31 sets each stop button 7L,
The stop operation position (the symbol on the center line 8c) when the stop signal generated from the reel stop signal circuit 46 is generated in response to the operation of 7C and 7R is confirmed, and the stop table is determined based on the stop operation position. A symbol stop position (a symbol to be stopped and displayed on the center line 8c) is determined (S
T72).

FIG. 17 shows the sub CPU 7 of the sub control circuit 72.
4 shows a procedure of a liquid crystal display control process performed in FIG. 4, and FIG. 18 shows a specific display mode on the display surface 5a of the liquid crystal display device 5.

First, the sub CPU 74 has the main control circuit 71

T81) If “YES” here, the sub CPU 74
Controls the image control circuit 81 to start the variable display of the numeric symbols on the display surface 5a of the liquid crystal display device 5.
FIG. 18A shows a display mode on the display surface 5a at this time.

Next, sub CPU 74 determines whether or not two seconds have elapsed since the start of the variable display (ST83).
If "YES" here, it is subsequently determined whether or not a probability table lottery winning command has been received (ST8).
4). Here, when “NO”, that is, when “probability table lottery loss”, the sub CPU 74
The image control circuit 81 is controlled so as to stop and display "4" of the numeral symbol in "a" (ST85). FIG. 18D shows a display mode on the display surface 5a at this time.

On the other hand, if “YES” in ST84, that is, if the probability table lottery winning command has been received, sub CPU 74 determines whether or not a stop table lottery winning command has been subsequently received (ST86). If “NO” here, that is, if “probability table lottery winning” and “stop table lottery loss”, the sub C
The PU 74 controls the image control circuit 81 so as to stop and display the numeral symbol “3” on the display surface 5a (ST87).
FIG. 18C shows a display mode on the display surface 5a at this time.

On the other hand, when "YES" in ST85, that is, when the stop table lottery winning command is received,
The sub CPU 74 controls the image control circuit 81 so as to stop and display the numeral symbol "7" on the display surface 5a (ST8).
8). Therefore, when the numeral symbol “7” is stopped and displayed on the display surface 5a, this is the case of “probability table lottery winning” and “stop table lottery winning”. FIG. 18B shows a display mode on the display surface 5a at this time.

Therefore, the stop display of the numeral symbol “7” as shown in FIG. 18 (2) allows the player to easily recognize that the winning has been achieved in the “probability table lottery” and the “stop table lottery”. Numerical pattern "3" as shown in 18 (3)
With the stop display of, the player can easily recognize that the winning has been achieved only in the “probability table lottery”, and by the stop display of the numeric symbol “4” as shown in FIG.
It is easy to recognize that only the “stop table lottery” has been won or both lotteries have been missed. That is, it is possible to easily identify before the stop operation whether or not the game state is advantageous for the player, such as an increase in the winning probability of the winning combination or an easy pull-in of a predetermined winning symbol.

Further, since the predetermined numerical symbols are stopped and displayed after the fluctuation display, during the fluctuation display, the player expects whether or not the current game is in an advantageous game state, and the interest of the game is increased. It will grow.
