DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine having a gaming state in which a special role can be easily won by a player performing an accurate operation in accordance with an instruction from the slot machine.

[0002]

2. Description of the Related Art In a conventional slot machine, a special role is won in a lottery of a role in a normal game, and when a combination of symbols of the special role is stopped on an active line, the normal game is shifted to a special game. The special game is a game that has a larger expected value of the number of medals obtained than the normal game and is advantageous for the player.

Here, BB (Big Bonus), RB (Regular Bonus), and SB (Single Bonus) are known as special roles, and BB games, RB games, SB games as corresponding special games, respectively. It has been known. Among these special games, the SB game is a special game consisting of one game. SB during normal game
When the combination of the symbols of the SB stops on the activated line, a winning of the SB is made, a predetermined number of medals are paid out, and the SB game is started. The SB game is a game in which one medal is inserted and a predetermined combination is won with a high probability. When a predetermined combination is won in the SB game, a predetermined number of medals are paid out. After the end of the SB game, the game returns to the normal game again.

Here, in the BB game and the RB game, it is expected that 100 to several hundred medals can be obtained in one special game. However, since the SB game is a special game consisting of one game, the medals that can be obtained in the SB game are B
Compared to B games and RB games, it is significantly less.

[0005] For this reason, there is known a slot machine provided with the role of SB, in which a game state in which the SB winning probability is a normal probability and a gaming state in which the SB winning probability is high are provided. Then, whether the winning probability of the SB is the normal probability or the high probability is determined by lottery. When the winning probability of the SB becomes high, the SB enters a gaming state in which the SB is frequently won and won. As described above, by generating a gaming state in which the SB winning probability is high, the SB winning and winning states are intensively generated, and the payout rate is changed.

[0006]

However, in the above-described conventional technique, since the winning probability of the SB is only changed, there is a problem that the game content of the slot machine becomes monotonous. Here, among the special roles, B
If the player wins B or RB, the winning is carried over until the BB or RB wins. On the other hand, the winning of the SB is valid only in the game concerned, and does not carry over the winning to the next game transition. Therefore, when the SB is won, the reels are controlled to stop so that the SB always wins.

Further, when the game shifts to the SB game, a predetermined combination is won with a high probability. When the predetermined combination is won, the reels are controlled to stop so that the predetermined combination always wins. For this reason, the player pays attention only to whether the winning probability of the SB is the normal probability or the high probability, and plays the game at the time of winning the SB and the game at the time of winning the predetermined role in the SB game. However, the user simply operated the stop switch. For this reason, there has been a problem that advanced slot machines often feel unsatisfactory.

Here, it is conceivable to prevent the won SB or predetermined combination from winning if the stop switch is not correctly operated on the symbol arrangement of the reels. However, as described above, the winning of the SB and the winning of the predetermined combination in the SB game (one game) are effective only in the game, so that the winning of the winning SB or the predetermined combination requires some skill. Is required, there is a problem that the difference between the number of medals obtained between the beginner and the advanced player is too large and the beginner is shunned.

[0009] Therefore, the problem to be solved by the present invention is to provide a difference between the players in the number of medals obtained based on the special combination (especially SB) or the predetermined combination during the special game (especially SB game). In addition, it is intended that even a beginner or an intermediate player can sufficiently acquire a medal.

A start switch 41 and a stop switch 42 that the player operates during the game are electrically connected to (middle, left). The start switch 41 is a switch operated when the player starts the rotation of the reel 31. In addition, three stop switches 42 are arranged independently for each reel 31 and are operated by the player when the rotation of each reel 31 is stopped.

FIG. 2 is a diagram showing each combination in the present embodiment, the number of paid out medals, and the winning probability in a probability table 62 (described later). Among the roles, in the present embodiment, three special roles are provided. Special role is BB
(Big Bonus), RB (Regular Bonus), and SB (Single Bonus). Where SB
Are the first special role in the present invention, and BB and RB
Is a second special role in the present invention. In addition, the small role,
There are three types (small wins 1 to 3). Furthermore, a replay (replaying role) is provided as another role.

Here, the probability obtained by subtracting the sum of the winning probabilities of all the roles from the probability 1/1 (100%) is the non-winning probability of not winning any of the roles. The non-winning probability in the probability table 62 is about 1/18. That is, in the probability table 62, the winning probability of the SB is 1 /
The highest is 1.5, which is higher than the non-winning probability.

For each combination, a combination of specific symbols corresponding to each combination is predetermined. When the combination of specific symbols corresponding to the winning combination stops on the active line when all the reels 31 are stopped, the winning combination is won and a predetermined number of medals are paid out for each winning combination.

Here, although not shown, the effective line is
It is displayed in a portion including the display window of the front panel, and for example, five are set. When there are five effective lines, the lines are composed of three lines in the upper, middle, and lower stages in the horizontal direction, and two lines in diagonal directions of lower right and lower left.

The role lottery means 61 includes, for example, a random number generating means (hard random number or the like) for a role lottery, a random number extracting means for extracting a random number generated by the random number generating means, and a random number value extracted by the random number extracting means. There is provided determination means for determining the presence or absence of a winning combination and determining the winning combination.

The random number generation means of the combination lottery means 61 generates a random number in a predetermined area (for example, 0 to 65535 in decimal system). The random number extracting means extracts the random number generated by the random number generating means at a predetermined time, in this embodiment, when the start switch 41 is turned on by the player. The determining means determines the combination corresponding to the area to which the random value belongs by comparing the random number value extracted by the random number extracting means with a probability table 62 described later. For example, if the extracted random number value belongs to the BB winning area, it is determined that the BB has been won, and if it belongs to the non-winning area, it is determined that it has not been won.

(Probability table) As shown in FIG. 2, the probability table 62 defines the winning probability of each role. The winning probability of the winning combination is usually determined for each number of inserted medals (1 to 3) and for each set value of the payout rate, but is omitted in the present embodiment.

The probability table 62 has a predetermined range of a lottery area, and the lottery area is divided into a winning area and a non-winning area of each combination. The winning area of each role in the lottery area in the probability table 62 is set at a predetermined ratio so as to have the winning probability shown in FIG.

(Special Role Winning and Carrying Means) The special role winning and carrying means 63 is a BB or RB in which the combination of symbols stopped on the active line after winning the BB or RB in the lottery of the role by the role lottery means 61 is determined in advance. In the game until the combination of the symbols of the RB matches, that is, in the game until the BB or the RB wins, the winning of the BB or the RB is carried over.

Here, in the lottery selection by the role lottery means 61, when the player wins a SB, a small role, or a replay, the winning of these roles is valid only in the game concerned, and after the next game, the role is played. Will not be carried over. That is,
If the combination of the symbols corresponding to the winning combination does not stop on the activated line (if the combination does not win), the winning of the combination becomes invalid at the end of the game.

On the other hand, when a BB or RB is won, the winning of the BB or RB is carried over after the next game until the BB or RB wins. Further, even in a game in which the winning of BB or RB is carried over by the special role winning carrying means 63, the role lottery means 61 performs the BB or R
The lottery of the role including B is continued.

Here, during the game in which the BB or RB is won and the BB or RB is carried over, the lottery means 6 is selected.
In the lottery of the role by 1, the random number value extracted temporarily is BB or R
It is known that, even if it belongs to the winning area of B, it is determined not to be a winning of BB or RB. In this case, the BB or RB will not win again.
However, in the present embodiment, the role lottery means 61 is BB or R
After the winning of B, the lottery of the role including BB or RB is performed. As a result, the BB or RB may win a plurality of times.

In the present embodiment, during the game in which the BB or RB is won in the lottery of the role by the role lottery means 61 and the BB or RB winning is carried over by the special role winning carryover means 63, the role lottery means 61 performs BB in lottery
Or, if you win the RB again,
Bring B or RB and BB or RB that has been re-elected. For example, when the BB is first elected and then the RB is elected, the first elected BB and the next elected R
B will carry over the election. The same applies to the opposite case. Also, after winning the BB, before winning the BB,
When winning B, the winning of two BBs is carried over. The same applies when two RBs are won.

In this embodiment, a counter is provided for counting the carryover of the winning of these BBs or RBs. For example, when BB or RB is won, 1 is added to the count value of the BB or RB counter, respectively. When BB or RB is won, the count value of each counter is decremented by one. For example, if the count value of the counter for BB is 2, RB
If the count value of the counter for
When the BB wins, the count value of the BB counter is decremented by one, and the count value of the BB counter is one.
Becomes In this case, the count value of the RB counter is maintained at 1.

(Reel Stop Control Means) The reel stop control means 64 controls a game state (for example, a normal game state or a special game state), a lottery result of the role lottery means 61, and a timing when the stop switch 42 is turned on. From the above, the stop position of the reel 31 is determined with reference to the reel stop control table 64a, and the drive of the motor 32 is controlled to
The reel 31 is controlled to stop at the determined position.

The reel stop control table 64a stores the lottery result of the role by the role lottery means 61 and the stop switch 42.
The stop position of the reel 31 is determined from the position of the reel 31 at the moment when is operated. In the lottery of the role by the role lottery means 61, the stop position of the reel 31 is determined so that the symbol combination of any of the roles does not stop on the activated line when no role is won. Further, when any of the winning combinations is won, the stop position of the reel 31 is determined so that the combination of the symbols of the winning combination can be stopped on the activated line.

Here, in the game in which the winning of BB or RB has been carried over and has not been won in the small role or replay,
The pull-in control of the symbol related to BB or RB is performed within the range of the stop control of the reel 31 so that the combination of symbols corresponding to BB or RB is stopped on the effective line as much as possible.

If a small role or a replay is won during a game in which a BB or RB winning is carried over, the win of the small role or the replay is prioritized. Therefore, at the time of winning the small role or replay, even if the winning of BB or RB is carried over, the stop position of the reel 31 is set so that the combination of the symbols of BB and RB does not stop on the activated line. Stipulated.

Further, in this embodiment, a plurality of reel stop control tables 64a are provided. The plurality of reel stop control tables 64a indicate whether the combination of specific symbols corresponding to the winning combination is stopped on the activated line when the combination lottery means 61 wins an SB or a predetermined combination in the SB game. And stop switch 4
The setting is made different depending on the operation order of No. 2.

That is, in one reel stop control table 64a, when a predetermined combination in the SB or SB game is won, the specific stop switch 42
When the operation is performed in the operation order (for example, right, middle, left), the combination of the specific symbols corresponding to the above combination is set to be stopped on the activated line. When the button is operated, it is set so that the combination of the specific symbols corresponding to the above combination is not stopped on the activated line.

In the other reel stop control table 64a, when a predetermined combination in the SB or SB game is won, another specific stop switch 42 is selected.
(For example, left, right, middle) in order to stop the SB or the specific symbol combination corresponding to the predetermined combination on the activated line, and the other operation order Is set so as not to stop the combination of the SB or the specific symbol corresponding to the predetermined combination on the activated line.

Here, when the stop switches 42 corresponding to the left, middle, and right reels 31 are represented by left, middle, and right, respectively, the operation order of the stop switches 42 is “left, middle, right”.
Middle, right, left, right, middle, middle, left, right, middle,
Right, left, right, left, middle, and right, middle, left. Then, each reel stop control table 64
a, when a predetermined combination is won during the SB or SB game, when the stop switch 42 is operated in any one of the operation orders, a combination of specific symbols corresponding to the SB or the predetermined combination is When the stop switch 42 is operated in any of the other five operation orders, the reels are stopped so that the specific symbol combination corresponding to the SB or the predetermined combination does not stop on the active line. 31 stop positions are determined.

FIG. 3 is a diagram showing a symbol arrangement of the reel 31 in the present embodiment. In FIG. 3, only the symbol arrangement of “BAR” and “plum” is shown, and a predetermined symbol is also displayed in a blank portion in the figure,
Here, the description is omitted. In FIG. 3, each reel 31
In the example, the symbols of “BAR” are all arranged at intervals of 5 symbols or less. Similarly, the symbols of “plum” are also arranged at intervals of not more than five symbols. And "BA
The combination of symbols "R"-"BAR"-"BAR" is SB
Is determined for a specific symbol combination corresponding to. Further, a combination of symbols “plum”-“plum”-“plum” is defined as a specific symbol combination corresponding to a predetermined combination in the SB game.

Here, as described above, the reel stop control means 64 controls the range of stop control of the reels 31 so that when a winning combination is won, the symbol combination corresponding to the winning combination is stopped on an effective line as much as possible. Within, the control of drawing in the symbol related to the combination is performed. In other words, if the symbol related to the role does not stop on the active line at the position where the stop switch 42 is detected at the time of winning the role, the reel 31 is controlled to move when the reel is stopped, so that the role is displayed on the active line. By actively stopping such symbols, the winning rate of the winning combination is increased.

The stop control of the reel 31 is usually performed by
It is set to 190 ms or less (within 5 symbols counted from the position where the stop switch 42 is detected to be on). Therefore, if the stop switch 42 is turned on when any of the symbols up to 5 symbols before the symbol related to the winning combination is located on the specific activated line, the symbol related to the winning combination is displayed on the specific activated line. Retraction control is performed.

Here, as shown in FIG.
, The symbols of “BAR” are all arranged at intervals within 5 symbols. Therefore, when the SB is won, no matter where the stop switch 42 is turned on, “BA
The symbol "R" can be drawn into the active line and controlled. Therefore, the symbol of “BAR” constituting the specific symbol combination corresponding to SB has a pull-in rate of 100%. The same applies to the symbol “Plum” that constitutes a specific symbol combination corresponding to the predetermined combination in the SB game.

The reel stop control means 64 includes a reel stop control lottery means 64b. The reel stop control lottery means 64b selects one of the plurality of reel stop control tables 64a by lottery when the winning lottery means 61 wins the predetermined combination during the SB or SB game. Is what you do.
Thus, when a predetermined combination is won during the SB or SB game, any one of the reel stop control tables 64a
Is selected, the operation order of the stop switch 42 for stopping a specific symbol combination corresponding to the predetermined combination in the SB or the SB game to the activated line is determined. As a method of selecting the reel stop control table 64a, for example, the same random number generating means as that described in the role lottery means 61 may be used.

(Winning determination means) The winning determination means 65 determines whether the combination of the symbols stopped on any of the activated lines when the reel 31 stops matches the predetermined combination of the symbols of any combination. Is determined. The winning determination means 65 determines the symbol located on the active line by detecting, for example, the angle when the motor 32 is stopped, the number of steps, and the like, and determines the presence or absence of a winning combination based on this.

The winning determining means 65 does not determine the symbol combination after the reel 31 is actually stopped, but the reel 3 at the moment when the stop switch 42 is operated.
When the stop position of the reel 31 is determined by the reel stop control table 64a from the position 1, it is also possible to determine the combination of symbols that stop on the activated line.

(Payout Means) The payout means 66 receives a prize when the winning determination means 65 determines that the combination of the symbols stopped on the activated line when the reel 31 is stopped coincides with the combination of the symbols of any combination. Depending on the role, a predetermined number of medals are paid out to the player, or processing such as credit addition is performed. At the time of winning a replay, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

(Special game execution means) Special game execution means 6
Reference numeral 7 controls the start of the special game, the progress of the game during the special game, the end of the special game, and the like. The special game execution means 67 shifts from the normal game to the special game on condition that the combination of the symbols stopped on the activated line matches a predetermined combination of symbols of the special combination.

The special game execution means 67 is a combination of specific symbols corresponding to BB (for example, "7"-"7"-
When “7”) stops on the activated line, the normal game is shifted to the BB game. Also, a specific symbol combination corresponding to RB (for example, “7”-“7”-“BA
When “R”) stops on the active line, the game is shifted from the normal game to the RB game. Furthermore, a combination of specific symbols corresponding to SB ("BAR"-"BAR" described above)
-When “BAR” stops on the active line, the game is shifted from the normal game to the SB game.

At the time of transition to the special game, the special game execution means 67 turns on the lamp 33, outputs a sound from the speaker 34, and outputs an image by the image display device 35 in order to inform the player that the game is to be shifted to the special game. The display is controlled to perform various effects.

The special game execution means 67 controls the progress of the game during the BB game, RB game and SB game. In the BB game, the special game execution means 6
7 starts the first game first. This first game is
Similar to the normal game, a game is performed by inserting medals within a predetermined number (for example, three). Combinations drawn by the combination lottery means 61 in the first game are a small combination and a transfer combination for shifting to the second game. In the first game, the upper limit of the number of games is predetermined to be, for example, 30 times. Then, the special game execution means 67 keeps counting the number of games in the first game.

The special game executing means 67 sets the condition that the combination of symbols stopped on the activated line during the first game matches the combination of symbols of the transfer combination, that is, the condition of the transfer combination winning. The game is shifted from the first game to the second game.

When the game is shifted to the second game, the special game execution means 67 counts the number of games during the second game and the number of winnings of the predetermined combination. In the second game, for example, only one medal can be inserted, and only the effective line in the middle stage in the horizontal direction is activated, and a combination of a specific symbol corresponding to the predetermined combination with a high probability of, for example, about 90% is provided on this activated line. (For example, the above-mentioned “plum” − “plum” − “plum”) is a game controlled to stop. Then, the second game is continued until the winning number of the predetermined combination reaches a specified number (for example, 8) or the number of games reaches the specified number (for example, 12). In order to determine whether or not the end condition of the second game is satisfied, the special game execution means 67 counts the number of games and the number of winnings of the predetermined combination.

When the number of games of the second game or the number of winnings of the predetermined combination reaches the specified number, the special game executing means 67 ends the second game and satisfies the BB game end condition. Again, subject to the absence of
Control to return to the game.

Here, in the BB game, the upper limit is set to the number of transitions from the first game to the second game up to a specified number (for example, three times). Therefore, when the second game ends when the specified number of times has been reached, the BB game is ended without shifting to the first game again. For this reason, the special game execution means 67 counts the number of times that the game has shifted from the first game to the second game during the BB game. For example, at the time of the first game in the BB game, the transfer role wins,
When shifting to a game, 1 is added to the number of shifts.

In the RB game, one set of the second game in the above BB game, that is, a combination of specific symbols corresponding to a predetermined combination (“plum” − “plum” − “plum”) has a high probability. The game stopped on the activated line is performed until the number of stipulated winnings or the number of stipulated games is reached. In the RB game, the special game execution means 67
It keeps counting the number of games or the number of winning of the predetermined combination.

Further, in the SB game, a game in the RB game is one game, that is, a combination of specific symbols (“plum”-“plum”-“plum”) corresponding to the predetermined combination is stopped at the activated line. Is performed only for one game.
However, in the SB game, a high probability (eg, about 90%)
As described above, only when the stop switch 42 is operated in a specific operation order, a specific symbol combination corresponding to the selected predetermined combination stops at the activated line, as described above. On the other hand, even if the predetermined combination is won, when the stop switch 42 is operated in an operation order other than the specific operation order, the combination of the specific symbols corresponding to the selected predetermined combination does not stop on the activated line. And reel 31
Is controlled to stop.

[0095] During the special game, the special game execution means 67
It is continuously determined whether or not the special game end condition is satisfied. When it is determined that the special game end condition is satisfied, the special game is ended.

When the special game is a BB game, the first game
When the number of games reaches the specified number of times, or when the number of transitions from the first game to the second game reaches the specified number of times, the number of games or the winning number of the predetermined role reaches the specified number of times in the second game. If you meet any one of the times,
The special game execution means 67 determines that the end condition of the BB game is satisfied. Further, when the special game is an RB game, and when one of the number of games or the number of winnings of the predetermined combination reaches a specified number is satisfied, the special game execution means 67 sets the RB game end condition. It is determined that the condition is satisfied.
Furthermore, when the special game is an SB game, the SB
When one game of the game is completed, the special game execution means 6
7 determines that the SB game end condition is satisfied.

(Winning notification control means) Winning notification control means 6
Reference numeral 8 denotes a stop in which when a predetermined combination is won during the SB or SB game by the combination lottery means 61, a combination of specific symbols corresponding to the selected SB or the predetermined combination is stopped by the reel stop control means 64 on an active line. In order to allow the player to know the operation order of the stop switch 42 for performing the control, the control is performed so as to notify the contents regarding the winning of the SB or the predetermined combination.

When any one of the reel stop control tables 64a is selected by the reel stop control lottery means 64b, the winning notification control means 68 specifies the SB or predetermined combination corresponding to the reel stop control table 64a. The operation order of the stop switch 42 for stopping the combination of symbols on the activated line is determined, and the operation order is controlled so as to be notified to the player.

As the notification method, various peripheral devices for outputting an effect can be used. In the present embodiment, an image is displayed on the image display device 35. For example, left,
By operating the stop switch 42 in the order of the middle and right, if it is possible to stop the combination of the specific symbols corresponding to the winning SB or the predetermined combination on the active line, for example, the image display device 35 displays " Left → Middle → Right ''
And image display. Other operation orders of the stop switch 42 include left, right, middle, middle, left, right, middle,
Examples include right, left, right, left, middle, right, middle, and left. These are also displayed as images.

Here, when the SB or the predetermined combination in the SB game is won, the winning notification control means 68 controls to notify immediately after the start switch 41 is turned on. Such control is performed for the following reason. SB
Alternatively, when a predetermined combination in the SB game is won, the winning is valid only in the game, and the winning cannot be carried over to the next game. In other words, if the combination of the symbols corresponding to the SB or the predetermined combination does not stop on the activated line in the game that has been selected to the predetermined combination in the SB or the SB game, the right to the winning is extinguished.

Therefore, at the time of winning the SB or the predetermined role,
In order to enable the stop operation of the reel 31 for stopping the winning SB or a specific symbol combination corresponding to the predetermined combination on the activated line, the control is performed so as to notify immediately after the start switch 41 is turned on. This is because a predetermined operation order is determined from the stop switch 42 to be operated first in order to stop the combination of the specific symbols respectively corresponding to the SB or the predetermined combination in the activated line.

(Game Mode Determining Means) Game Mode Determining Unit 6
9 determines whether to use the notification game mode in which the notification by the winning notification control means 68 is performed or the non-report game mode in which the notification by the winning notification control means 68 is not performed. In the present embodiment, during the game in the non-announced game mode, the game mode determination unit 69 determines that
It is determined whether or not the notification game mode in which the notification is to be performed. When the game in the notification game mode has reached the determined continuous game period, the game mode is determined to be the non-report game mode.

Further, the game mode determining means 69 refers to a predetermined game history to determine whether the game mode is the notification game mode or the non-report game mode. In particular, in the present embodiment, during the game in the non-notification game mode, the game mode determination means 69 is a stop switch in the order of left, middle, and right (forward push) by the reel stop control lottery means 64b during the SB win. When the reel stop control table 64a defined to stop the SB or the specific symbol combination corresponding to the predetermined combination on the activated line when the 42 is operated is notified at a probability of 1/100 when the reel stop control table 64a is selected. It decides to make an aspect.

For example, in the game in the non-notification game mode, the game mode determination means 69 selects the reel stop control table 64a in which the SB is won and the operation order of the stop switch 42 is left, middle, and right. In this case, a 1/100 lottery is performed using soft random numbers. Then, when this lottery is won, the game mode determining means 69 determines that the notification game mode is set.

Here, the winning probability of the SB is 1 / 1.5. Further, when the stop switch 42 is operated in the order of left, middle, and right, the reel stop control table 64a which is set to stop the SB or the specific symbol combination corresponding to the predetermined combination on the activated line is selected. Probability is 1/6
It is. Therefore, the probability of being determined to be the notification game mode during the game of the non-report game mode is 1 / 1.5 × 1/6 × 1/100 = 1/900.

Although not shown, the game control means 60
Has a notification game flag as a flag for determining whether or not the game is the notification game mode. During the game in the notification game mode, the notification game flag is turned on. On the other hand, during the game in the non-report game mode, the report game flag is turned off.

(Notification Game Period Determining Means) The notification game period determining means 70 determines the continuous game period of the notification game mode when the game mode determining means 69 determines that the notification game mode is set. In the present embodiment, the notification game period determining means 70 determines the continuous game period by lottery.

FIG. 4 is a diagram showing a probability table used by the notification game period determining means 70 to determine a continuous game period.
As shown in FIG. 4, the determined continuous game period is 5
0 games, 100 games, 200 games, and thereafter up to 2000 games are set for every 100 games. Then, a winning probability is set for each continuous game period.
Specifically, 1 to 50 to 500 games
It has a winning probability of 10. Further, from 600 to 1000 games, each has a winning probability of 1/20. Furthermore, there is a 1/50 winning probability from 1100 to 1500 games. Further, there is a winning probability of 1/100 from 1600 to 2000 games. One of these is selected using, for example, a soft random number.

When the number of continuous games in the notification game mode reaches the number of games determined by the notification game period determination module 70, the game mode determination means 69 terminates the game in the notification game mode and returns to the non-report game. It is determined that the game of the mode is performed.

(Information Game Mode Interruption Means) The notification game mode interruption means 71 executes the game of the non-information game mode when a predetermined condition is satisfied even during the game of the notification game mode, When the condition for releasing the game mode is satisfied, control is performed so that the game in the notification game mode is restarted. In particular, in the present embodiment, when the player wins BB or RB during the game in the notification game mode, the game in the notification game mode is interrupted, and the game in the non-report game mode is executed. And
When the BB game or the RB game is completed, control is performed so that the game in the notification game mode is restarted.

For this reason, the notification game mode interruption means 71
When the player wins BB or RB during the game in the notification game mode, the counting of the number of games is interrupted, and the number of games up to that time is stored in a predetermined storage means such as a RAM. Then, when the BB game or the RB game ends and the game shifts to the game of the notification game mode again, the number of games stored in the storage means is read out, and the number of games of the notification game mode is set.

(Operation order detecting means) Operation order detecting means 7
Reference numeral 2 is used to detect the operation order of the stop switch 42 when an SB is won or when a predetermined combination is won during the SB game. As described above, the stop switch 42
Are provided for each of the reels 31. The first (first) stop switch 42 turned on is the stop switch 42 corresponding to any of the left, middle, and right reels 31. Alternatively, the stop switch 42 that is turned on second is the left, middle, or right reel 3.
Among them, it is detected which reel 31 the stop switch 42 corresponds to. Each stop switch 42 is configured to transmit an identification signal to the operation order detecting means 72 when it is turned on.

The reel stop control means 64 determines the stop position of the reel 31 with reference to the selected reel stop control table 64a based on the detection result by the operation order detecting means 72, and places the reel 31 at that position. Stop control.

As described above, in the game of the notification game mode,
When the SB or the predetermined combination in the SB game is won, the operation order of the stop switch 42 is notified as described above, so that the player can know from the notification that the SB or the predetermined combination has been won. Further, if the stop switch 42 is turned on in accordance with the notified order (in accordance with the order instructed by the slot machine 10), the combination of the winning SB or a specific symbol corresponding to the predetermined combination is stopped on the activated line, and a medal is obtained. can do. That is, the pull-in rate of each symbol of “BAR” or “Plum” constituting the combination of the specific symbols corresponding to the SB or the predetermined combination is set to 100%.

On the other hand, during the game in the non-notifying game mode,
Even when the predetermined combination is won in the SB or the SB game, the operation order of the stop switch 42 for stopping the combination of the specific symbols corresponding to the SB or the predetermined combination on the activated line is not notified. Therefore, when a predetermined combination is won in the SB or SB game during the game in the non-reporting game mode, the operation of the stop switch 42 for stopping the combination of the specific symbols corresponding to the SB or the predetermined combination on the activated line. If the order and the order in which the player operates in the game match, the combination of the specific symbols corresponding to the SB or the predetermined combination stops at the active line,
In other operation orders, the combination of specific symbols corresponding to SB or the predetermined combination does not stop on the activated line.

As described above, since there are six operation orders, during the game in the non-notification game mode, when a predetermined combination is won during the SB or SB game, a specific symbol combination corresponding to each is valid. The probability of stopping at the line is 1/6.

Therefore, in the game in the notification game mode and the game in the non-report game mode, when the SB or the predetermined combination in the SB game is won, the probability that the corresponding specific symbol combination stops on the active line is 6%. The difference will be doubled. Here, it is assumed that three medals are inserted in each game and a game is performed, and one medal is inserted and a game is performed during the SB game. Further, the winning probability of the predetermined combination in the SB game is set to 9/10, and when the SB or the predetermined combination in the SB game is won, the corresponding combination of the specific symbols is stopped at the activated line with a probability of 100% in the notification game mode. Assuming that, in the notification game mode, the number of obtained medals based on the SB and the predetermined combination during the SB game is 1 / 1.5 (SB winning probability) × 6 (SB payout number) + 1 / 1.5 × 9/10 (the winning probability of the predetermined combination at the time of transition to the SB game) × 15 (the number of payouts of the predetermined combination in the SB game) = 13.

In the game at the time of winning the SB, three medals are inserted, and in the SB game, one medal is inserted. Therefore, the total number of inserted medals is four. Therefore, the net increase in number based on the SB and the SB game in the notification game mode is 13-4 = + 9. Further, the rate of increase and decrease of the medals by the SB winning and the SB game is 13/4 = 325%.

On the other hand, in the game of the non-notifying game mode,
The probability that the combination of the symbols corresponding to the SB and the predetermined combination in the SB game is stopped on the activated line is 1/6 of the time of the game in the notification game mode, so 1 / 1.5 (SB winning probability) × 1/6 × 6 (SB payout number) + 1 / 1.5 × 1/6 × 9/10 (winning probability of predetermined combination at transition to SB game) × 1/6 × 15 (S
The number of payouts for the predetermined combination in the B game) = 0.92.

Similarly to the above, three medals are inserted in the game at the time of winning the SB, and one medal is inserted in the SB game. Therefore, the total number of inserted medals is 3 + 1 × 1/6 = 3.17. Becomes Therefore, the net increase in number based on the SB and the SB game in the non-notifying game mode is 0.92-3.17 = -2.25. In addition, the rate of increase / decrease of the medal by the SB winning and the SB game is 0.92 / 3.17 = 29%.

As described above, the difference between the increase / decrease rate of the medal based on the SB and SB games in the notification game mode and the non-report game mode is 325/29 = 11.2 times.

Here, in the conventional slot machine,
Considering the increase / decrease rate of medals, although the SB winning and winning states are intensively generated. In conventional slot machines,
The winning and winning probability of the SB in the normal probability and the high probability is 1
It was about 0 times. For example, assuming that the SB winning probability at the time of the high probability is 1 / 1.5 as in the present embodiment, the winning probability of the SB at the time of the normal probability is 1/10 (1/15) thereof.

At this time, when the probability is high, 1 / 1.5 (SB winning probability) × 6 (SB payout number) + 1 / 1.5 × 9/10 (predetermined winning at the time of transition to the SB game) (Probability) × 15 (the number of payouts of the predetermined combination in the SB game) = 13, which is the same as in the present embodiment.

On the other hand, the normal probability is: 1/15 (SB winning probability) × 6 (SB payout number) + 1/15 × 9/10 (winning probability of predetermined role at the time of transition to SB game) × 15 (the number of payouts of the predetermined combination in the SB game) = 1.3.

Therefore, in the case of the conventional slot machine, the winning and winning probabilities of the SB have a 10-fold difference between the high probability and the normal probability. On the other hand, in the present embodiment, S
The probability that the specific symbol combination corresponding to B stops on the activated line is a six-fold difference between the notification game mode and the non-report game mode. However, in the present embodiment, the probability that the specific symbol combination corresponding to the predetermined combination in the SB game stops on the activated line also becomes a six-fold difference between the notification game mode and the non-report game mode. Therefore, in the case of the conventional slot machine, the number of medals obtained at the normal probability is 1.3, whereas in the present embodiment, it is 0.92. As a result, the difference in the medal increase / decrease rate between the notification game mode and the non-report game mode is 11.2 times, which is 10 times or more the value of the conventional slot machine.

Thus, the difference in the medal increase / decrease rate between the notification game mode and the non-report game mode can be made larger than that of the conventional slot machine.

Next, the flow of the game of the slot machine 10 will be described with reference to a flowchart. FIG.
FIG. 10 to FIG. 10 are flowcharts illustrating the flow of a game in the present embodiment. FIG. 6 is a flowchart following FIG. FIG. 7 is a flowchart subsequent to “2” in FIG. FIG. 8 is a flowchart subsequent to “5” in FIG. FIG. 9 is a flowchart showing the operation of step S59 in FIG.
5 is a flowchart showing processing during the SB game when the SB game is started. FIG. 10 shows “7” in FIG.
It is a flowchart following the following.

First, the player inserts medals into the slot machine 10 by inserting medals from a medal insertion slot (not shown) or operating a bet switch (not shown) to activate the activated line. Then, the start switch 41 is turned on. In step S1, the game control means 60 continues to detect whether or not the start switch 41 has been turned on.
Is started, and the process proceeds to the next step S2. In step S2, the game control means 60 determines whether or not the notification game flag is on. If it is determined that the game is on (informing game mode), the process proceeds to step S3. If it is determined that the game is not on (non-report game), the process proceeds to step S4.

In step S3, the game control means 60
An update process of the number of games in the notification game mode is performed. That is,
Since the game is started when the start switch 41 is turned on, a process of adding 1 to the number of games P in the notification game mode (P = P + 1) is performed. Then, the process proceeds to step S4.

In step S4, the combination lottery means 61 performs lottery selection. Next, the process proceeds to step S5, where the special role (B
B, RB, or SB) is determined, and if it is determined that no win has been made, the process proceeds to step S13 in FIG. 6, and if it is determined that a win has been made, the process proceeds to step S6. In step S6, it is determined whether or not the winning special combination is BB. When it is determined to be BB, the process proceeds to step S7, and when it is determined that it is not BB (RB or SB), the process proceeds to step S8.

In step S7, the special role winning carry-over means 63 adds 1 to the count value X of the BB counter (X = X + 1), and proceeds to step S10. In step S8, it is determined whether or not the winning special combination is RB. If it is determined to be RB, step S9
When it is determined that it is not RB (it is SB), the process proceeds to step S31 (FIG. 7). In step S9, the special role winning carry-over means 63 adds 1 to the count value Y of the RB counter (Y = Y + 1), and step S10
Proceed to.

In step S10, it is determined whether or not the notification game flag is on. If it is determined that the notification game flag is on, the process proceeds to step S11. In step S11, the game control means 60 stops updating the number of games in the notification game mode. Further, the game control means 60 stores the number of games in the notification game mode at this time in a predetermined storage means. In the next step S12, the game control means 60 turns off the notification game flag. Then, the process proceeds to step S13 in FIG. On the other hand, when it is determined in step S10 that the notification game flag is not on, the process proceeds to step S13.

At step S13, the game control means 6
When 0 is detected, whether or not the stop switch 42 is turned on is continuously detected. When the stop switch 42 is turned on, the process proceeds to step S14. In step S14, the reel stop control means 64
The lottery result of the role in step S4 and the stop switch 4
Based on the timing at which the reel 31 is operated, the stop position of the reel 31 is determined with reference to the reel stop control table 64a, and the reel 31 is moved to the determined position.
Stop control.

In the next step S15, the game control means 6
If 0, it is determined whether all the reels 31 have stopped or not. If it is determined that all the reels 31 have stopped, the process proceeds to step S16. On the other hand, if it is determined in step S15 that all the reels 31 have not stopped, the process returns to step S13.

In the step S16, the winning determination means 65
Determines whether the symbol combination corresponding to each of the special combinations BB, RB or SB has stopped on the activated line, that is, whether or not each special combination has won. When it is determined that the special combination has been won, the flow proceeds to "5" (step S51 in FIG. 8) in the figure. On the other hand, when it is determined that the special combination has not won, the process proceeds to step S17, and the winning determination unit 65 determines whether a small combination other than the special combination or a replay has won.

If it is determined in step S17 that a small role or a replay has been won, the process proceeds to step S18,
The payout means 66 performs processing such as payout of medals according to the winning combination. At the time of winning the small combination, payout processing of the number of medals corresponding to the small combination is performed, and the process proceeds to step S19. Further, at the time of winning the replay, a re-game processing is performed while maintaining the number of medals inserted in the game, and step S19
Proceed to. On the other hand, if it is determined in step S17 that no small winning combination has been won, that is, if no winning combination has been won, the process proceeds to step S19 without performing payout or the like.

In the step S19, the game control means 60
Determines whether or not the notification game flag is ON, and when it is determined that the notification game flag is not ON, the processing according to this flowchart ends. On the other hand, when it is determined that the switch is on, the process proceeds to step S20. In step S20, the game mode determination means 69 determines whether or not the number of games P in the notification game mode has reached the specified number of times Z.

If it is determined that the number of games P in the notification game mode has reached the specified number Z, the process proceeds to step S21, where the game mode determination means 69 determines the game mode to the non-notification game mode, and the game control means 60. Switches the notification game flag from on to off. That is, when the number of games in the notification game mode reaches the specified number, control is performed so as to end the game in the notification game mode. On the other hand, if it is determined in step S20 that the number of games P in the notification mode has not yet reached the specified number of times Z, the processing according to this flowchart ends.

Steps S8 in FIG. 5 to S in FIG.
At step 31, the reel stop control lottery means 64b performs a lottery of the reel stop control table 64a, selects one of the reel stop control tables 64a, and proceeds to step S
Go to 32.

In the step S32, the game control means 60
Determines whether the notification game flag is on. When it is determined that the switch is on, the process proceeds to step S38, and when it is determined that the switch is not on, the process proceeds to step S33. In step S33, the game mode determination unit 69 determines whether or not the reel stop control table 64a according to the operation order of the stop switch 42 is sequentially pressed (in order of left, middle, right).

If it is determined in step S33 that the selected reel stop control table 64a is not related to the forward push, the process proceeds to step S39. If it is determined that the selected reel stop control table 64a is related to the forward push, the process proceeds to step S34. move on. In step S34, the game mode determining means 69 determines (lottery) whether or not to use the notification game mode. As described above, the notification game mode is determined with a winning probability of 1/100.

Then, the process proceeds to a step S35, wherein it is determined whether or not the lottery in the step S34 is won. If it is determined that the lottery has been won, the process proceeds to step S36. If it is determined that the lottery has not been won, the process proceeds to step S39.
Proceed to. In step S36, the notification game flag is turned on. Then, the process proceeds to step S37, where the notification game period determining means 70 determines the continuous game period of the notification game mode by lottery. The determined continuous game period is stored in a predetermined storage unit. Then, the process proceeds to step S38.

In the step S38, the winning notification control means 6
8 is to inform the player about the winning of the SB so that the player can know the operation order of the stop switch 42 for performing the stop control for stopping the specific symbol combination corresponding to the SB on the activated line. Control. As described above, the image display device 35 and the like are used for the notification. Then, the process proceeds to step S39.

In step S39, the game control means 60
Continuously detects whether or not the first (initial) stop switch 42 is turned on. When ON is detected, the process proceeds to step S40. In step S40, the operation order detecting means 72 detects whether the left, middle, or right stop switch 42 has been turned on, and proceeds to step S41.

In step S41, the reel stop control means 64 corresponds to the first stop switch 42 based on the reel stop control table 64a selected in step S31 and the first stop switch 42 detected in step S40. The stop control of the first reel 31 is performed.

Next, proceeding to step S42, the game control means 60 continues to detect whether or not the second (second) stop switch 42 is turned on. When ON is detected, the process proceeds to step S43. In step S43, the operation order detecting means 72 detects whether the left, middle, or right stop switch 42 has been turned on. Then, the process proceeds to step S44. In step S44, the reel stop control means 64 controls the stop of the second reel 31 corresponding to the second stop switch 42, as in step S41.

Next, proceeding to step S45, the game control means 60 continues to detect whether or not the third (third) stop switch 42 has been turned on. When ON is detected, the process proceeds to step S46. In step S46, the reel stop control means 64 determines in step S41 and step S41.
Similarly to 44, the third reel 31 corresponding to the third stop switch 42 is stopped and controlled. Then, step S16
Proceed to (FIG. 6). Here, the reason why the third stop switch 42 is not detected after step S45 is that the third stop switch 42 can be determined since the first and second stop switches 42 have already been detected.

If it is determined in step S16 in FIG. 6 that the special combination has been won, the process proceeds to step S51 in FIG. In step S51, the winning determination means 65
Determines whether or not a BB has won, that is, whether or not a specific symbol combination corresponding to the BB has stopped on an active line. If it is determined that BB has won, step S5
The process proceeds to step S2, and if it is determined that the BB has not won, the process proceeds to step S55.

In step S52, the special role winning carry-over means 63 subtracts 1 from the count X of the BB counter (X = X-1), and proceeds to step S53, where the special game execution means 67 executes the BB game. To start. When the BB game is started, the process proceeds to step S54, in which the special game execution means 67 advances the BB game and continues to determine whether or not the BB game end condition is satisfied. If it is determined that the end condition of the BB game is satisfied, step S
Go to 61.

On the other hand, in step S55, the winning determination means 65 determines whether or not the RB has been won, that is, whether or not the specific symbol combination corresponding to the RB has stopped on the active line. When it is determined that the RB has won, the process proceeds to step S56, and when it is determined that the RB has not won, that is, when the specific symbol combination corresponding to the SB has stopped at the activated line, the process proceeds to step S59.

In step S56, the special role winning carry-over means 63 subtracts 1 from the count value of the RB counter (Y = Y-1), and proceeds to step S57, where the special game execution means 67 executes the RB game. To start. When the RB game is started, the process proceeds to step S58, where the special game execution means 67 advances the RB game and continues to determine whether or not the RB game end condition is satisfied. If it is determined that the condition for ending the RB game is satisfied, step S
Go to 61.

On the other hand, when proceeding to step S59, the special game execution means 67 starts the SB game. When the SB game is started, the process proceeds to step S60, where the special game execution means 67 proceeds with the SB game and continues to determine whether or not the end condition of the SB game is satisfied. If it is determined that the condition for ending the SB game is satisfied, the process proceeds to step S21 in FIG. 6 and ends.

In the step S61, the game control means 60
Determines whether the update of the number of notification games has been stopped in step S11. This determination is made in step S
The determination is made based on whether or not the number of games at the time when the updating of the number of games in the notification game mode is stopped in 11 is stored in a predetermined storage unit. When it is determined that the update of the number of games in the notification game mode is stopped, the process proceeds to step S62.

In the step S62, the game control means 60
Turns on the notification game flag, and proceeds to step S63. In step S63, the number of games in the notification game mode immediately before winning the special combination (BB or RB), that is, the number of games stored in the above-mentioned predetermined storage means is set. Thus, the game in the notification game mode is restarted after the next game. Then, the processing according to this flowchart ends. On the other hand, when it is determined in step S61 that the update of the number of games in the notification game mode has not been stopped, the processing according to the present flowchart ends.

FIG. 9 is a flowchart showing in more detail the processing from when the SB game is started in step S59 (FIG. 8) to when it is determined in step S60 that the SB game has ended. First, step S59
When the SB game is started in step S
Go to 71. In step S71, the game control means 6
If 0 is detected, whether or not the start switch 41 is turned on is continuously detected. When the start switch 41 is detected, each reel 31 is started and the process proceeds to the next step S72. In step S72, the combination lottery means 61 performs lottery of a combination peculiar to the SB game. That is, the lottery of the predetermined combination is performed. And
Proceeding to step S73, it is determined whether or not the predetermined combination has been won. If it is determined that no winning has been won, step S7 is determined.
Then, if it is determined that the winning has been achieved, the process proceeds to step S81 in FIG.

In the step S74, the game control means 60
Continues to detect whether or not the stop switch 42 is turned on, and when the stop switch 42 is turned on, the process proceeds to step S75. In step S75, the reel stop control means 64
Based on the timing when the stop switch 42 is operated, the stop position of the reel 31 is determined with reference to the reel stop control table 64a, and the stop of the reel 31 is controlled to the determined position. Here, since the predetermined combination has not been won, the stop control of the reel 31 is performed so that the combination of the specific symbols corresponding to the predetermined combination does not stop on the activated line.

In the next step S76, the game control means 6
If 0, it is determined whether all the reels 31 have stopped. If it is determined that all the reels 31 have stopped, the process proceeds to step S77. On the other hand, when it is determined in step S76 that all the reels 31 are not stopped, the process returns to step S74.

In the step S77, the winning determination means 65
Determines whether the combination of the specific symbols corresponding to the predetermined combination has stopped on the activated line (whether the predetermined combination has won). If it is determined that the predetermined combination has been won, step S
Proceed to 78. In step S78, the payout unit 66
The processing of paying out medals according to the predetermined combination is performed. And
Proceeding to step S79, the SB game ends. on the other hand,
If it is determined in step S77 that the predetermined combination has not been won, that is, if no combination has been won, the process proceeds to step S79 without performing processing such as payout, and the SB game ends.

In step S73, a predetermined role is won,
In step S81, the reel stop control lottery means 6
4b performs a lottery of the reel stop control table 64a,
One of the reel stop control tables 64a is selected, and the process proceeds to step S82.

In the step S82, the game control means 60
Determines whether the notification game flag is on. When it is determined that the switch is on, the process proceeds to step S83. When it is determined that the switch is not on, the process proceeds to step S84 without performing the process of step S83. In step S83, the winning notification control means 68 determines a predetermined order so that the player can know the operation order of the stop switch 42 for performing the stop control for stopping the specific symbol combination corresponding to the predetermined combination on the activated line. Control is performed so as to notify the contents regarding the winning of the role. As described above, the notification includes the image display device 3
5 and the like are used. Then, the process proceeds to step S84.

In the step S84, the game control means 60
Continuously detects whether or not the first (initial) stop switch 42 is turned on. When ON is detected, the process proceeds to step S85. In step S85, the operation order detecting means 72 detects whether the left, middle, or right stop switch 42 has been turned on, and proceeds to step S86.

In step S86, the reel stop control means 64 corresponds to the first stop switch 42 based on the reel stop control table 64a selected in step S81 and the first stop switch 42 detected in step S85. The stop control of the first reel 31 is performed.

Next, proceeding to step S87, the game control means 60 continues to detect whether or not the second (second) stop switch 42 is turned on. When ON is detected, the process proceeds to step S88. In step S88, the operation order detecting means 72 detects whether the left, middle, or right stop switch 42 has been turned on. Then, the process proceeds to step S89. In step S89, the reel stop control means 64 controls the stop of the second reel 31 corresponding to the second stop switch 42, as in step S86.

Next, proceeding to step S90, the game control means 60 continues to detect whether or not the third (third) stop switch 42 has been turned on. When ON is detected, the process proceeds to step S91.

In step S91, the reel stop control means 64 performs the same operation as in steps S86 and S89.
The stop control of the third reel 31 corresponding to the third stop switch 42 is performed. Then, the process proceeds to step S77 (FIG. 9). Here, the reason why the third stop switch 42 is not detected after step S90 is that the third stop switch 42 can be determined because the first and second stop switches 42 have already been detected.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications as described below are possible. (1) In the present embodiment, the game mode determination unit 69 refers to a predetermined game history to determine whether the game mode is the notification game mode or the non-report game mode. The game history may be determined with reference to other game histories other than the game history, such as the type of the winning combination, the number of games, the number of medals acquired in the BB game, and the like.

(2) In the present embodiment, the notification game period determining means 70 determines the continuous game period of the notification game mode without referring to a predetermined game history. May be determined with reference to the game history.

(3) In the present embodiment, the continuous game period of the notification game mode is determined by the notification game period determination means 70. However, without providing the notification game period determining means 70, it may be determined whether or not to continue the notification game mode by each game, lottery, or the like.

For example, when the game mode determination means 69 wins the SB during the game in the notification game mode, the game mode determination means 69 (regardless of which reel stop control table 64a is selected by the reel stop control lottery means 64b). / 30
With a probability of 0, a non-notifying game mode is determined. The lottery with a probability of 1/300 is determined by the game mode determining means 69.
In the same way as the 1/100 lottery, soft random numbers can be used. Here, since the winning probability of the SB is 1 / 1.5, the probability of being determined to be the non-informing game mode during the game of the informing game mode is 1 / 1.5 × 1/300 = 1/450.

[0170] When the notification game mode is changed to the non-notification game mode as described above, the counting of the number of games in step S3 in the flowchart shown in the embodiment is unnecessary. Further, when the player wins BB or RB during the game in the notification game mode, the notification game flag is changed from ON to OFF in place of the processing from step S10 to step S12.
Then, after the end of the BB game or the RB game, the process of turning on the notification game flag may be performed again instead of the process from step S61 to step S63.

Further, the processing from step S19 to step S21 is unnecessary. Further, step S3
If the notification game flag is on in step 2, it is determined whether or not to continue the notification game mode by lottery or the like. If the notification game mode is to be continued, the process proceeds to step S38. Turn off and proceed to step S39. Further, the lottery for the continuous game period of the notification game mode in step S37 is unnecessary.

(4) In the present embodiment, the probability table 62
Provided only one. However, without being limited to this, a first probability table in which the SB winning probability is set to a normal probability (for example, 1/15 corresponding to 1/10 of the present embodiment),
A second probability table in which the SB winning probability is set to a high probability (for example, 1 / 1.5 which is the same as in the present embodiment);
Probability table selecting means for selecting a probability table used in the role lottery means 61 may be provided. The probability table selecting means may select the probability table by lottery, or switch the probability table when a predetermined condition is satisfied by referring to a game history or the like.

In this way, in addition to the game state where the SB winning probability is the normal probability and the high probability, the SB winning time is determined when the SB is won.
The game mode is further diversified by providing a notification game mode in which the operation order of the stop switch 42 for stopping a specific symbol combination corresponding to the active line is stopped and a non-report game mode in which no notification is performed. Can be.

(5) In the present embodiment, the effect contents when the information game mode is determined are not mentioned,
When the notification game mode is determined, an effect for notifying the player of the determination may be output using the lamp 33, the speaker 34, the image display device 35, or the like. Similarly, when ending the game in the notification game mode, an effect to that effect may be output.

(6) When the mode is determined to be the notification game mode, the effect is not output immediately in the game, but is output during a predetermined number of games after the next game. A game in a game mode may be executed. In this case, after the determination of the notification game mode by the game mode determination means 69, until the execution of the game of the notification game mode, the notification game mode internal medium state is provided, and the notification game mode internal medium state is set. During the game, there is provided a determination result effect control means for controlling to output an effect regarding the determination result of the game mode determination means 69.

For example, after the notification game mode is determined, S
B, and when the stop switch 42 is operated in the order of left, middle, and right (forward push) by the reel stop control lottery means 64b, a specific symbol combination corresponding to SB is stopped on the activated line. Until the reel stop control table 64a set in (1) is selected, the notification game mode is set to the inside state. Then, until the reel stop control table 64a is selected, an effect to the effect that the game in the notification game mode is executed is output. In addition, among the effects related to the determination result of the game mode determining means 69, an effect indicating that the game in the notification game mode is not executed may be output.

(7) In the present embodiment, the notification by the winning notification control means 68 is performed in the notification game mode in the game during the SB game. This game may be performed similarly in the second game in the BB game, for example. In other words, the predetermined combination is won with a high probability, but unless the stop switch 42 is operated in a specific operation order, control is performed so that a specific combination of symbols corresponding to the predetermined combination does not stop on the active line. As in the above-described embodiment, in the second game of the BB game, one of the reel stop control tables 64a is selected by the reel stop control lottery means 64b, and the reel 31 is stopped and controlled based on the selected reel stop control table 64a. Just do it.

(8) When a plurality of winnings of BB or RB are carried over, winning conditions of the BB or RB that carries over the winning may be provided. For example, in the game of the notification game mode, during the continuous game period, the reel 31 is controlled to stop so that the BB or RB does not win. To do. And after the end of the game of the notification game mode,
The BB or RB that has won the winning may be allowed to win.

(9) In the present embodiment, when the SB and the predetermined combination in the SB game are won, the notification game mode or the non-report game mode is set. However, the present invention is not limited to this, and only one of the winning times may be set to the notification game mode or the non-report game mode.
