An embodiment of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram schematically showing a first embodiment of a slot machine according to the present invention. The game control means 60 of the slot machine 10
This is a means for totally controlling the entire slot machine 10 including the progress and effects of the game 0. The game control means 60 includes a CPU for performing calculations and the like, a ROM for storing programs necessary for the progress of the game and the like, data for effects, and data and the like fetched when the CPU performs various controls. And a RAM for temporarily storing the data.

On the output side (the right side in FIG. 1) of the game control means 60, peripheral devices such as a motor 32 described below are electrically connected. The motor 32 is for rotating the reel 31, is connected to the rotation center of the reel 31, and is controlled by the game control means 60.

The reel 31 has a ring shape, and has a plurality of types of symbols (eg, symbols constituting a winning combination) on its outer peripheral surface.
Is attached to the reel tape. For example, 21 symbols are provided on one reel 31 at equal intervals. In this embodiment, three reels 31 are provided in parallel. Further, each reel 31 is displayed from a display window (not shown) provided on the front panel of the slot machine 10.
It is arranged so that three symbols continuous up and down can be seen.
Therefore, the symbols are arranged so that a total of nine symbols can be seen from the display window of the slot machine 10. And reel 3
1 is rotated by the motor 32, so that the reel 31
The upper symbol is moved up and down in the display window at a predetermined speed.

Various combinations corresponding to combinations of symbols on the reel 31 are predetermined. When all the reels 31 are stopped, if the combination of symbols stopped on the activated line (described later) matches the combination of symbols of a predetermined combination, the combination is won. The winning combination includes, for example, a special combination, a plurality of small combinations, and a replay (replay combination). The special combination is a combination that shifts from a normal game to a special game (a game that is advantageous to the player). Types of special combinations include a big bonus (hereinafter abbreviated as BB), a regular bonus (hereinafter abbreviated as RB), a single bonus (hereinafter abbreviated as SB), and the like. With the winning of each of the special roles of BB, RB and SB, the normal game is shifted to each of the special games of the BB game, RB game and SB game.

The small combination is a combination in which a predetermined number of medals are paid out, and a plurality of small combinations are usually provided. In addition, the replay is a role that enables the player to perform a replay while maintaining the number of inserted medals (the number of bets) in the game.

For example, the special combination of symbols is "7"-
Assuming that “7” − “7” is set, when all the reels 31 stop and the symbol “7” of each reel 31 stops on any one of the activated lines, a BB winning is determined. Become.

Here, although not shown, for example, five effective lines are set in a portion including the display window of the front panel. This effective line is composed of three lines in the upper, middle, and lower stages in the horizontal direction, and two lines in the diagonally downward and rightward directions. The three symbols that are continuous from above and below the reel 31 viewed from each display window are located on three effective lines in the upper, middle, and lower rows in the horizontal direction. This activated line is activated according to the number of inserted medals. When one medal is inserted, one effective line in the middle stage in the horizontal direction is activated. When two medals are inserted, all three activated lines in the horizontal direction are activated. When three medals are inserted, all five activated lines are activated. You.

The small role election notifying means 24, under certain conditions,
Particularly, in the present embodiment, when a specific small winning combination is won during a specific game to be described later, this is for notifying the player. In the present embodiment, the small role winning notification means 24 notifies which type of the specific small role has been won when the specific small role is won. For example, the small role winning notification means 24 is configured by a liquid crystal image display device, a dot display, or the like, and displays the type of the specific small role that has been won by these. In addition to the image display, lighting of the lamp in a specific pattern, output of a specific sound from a speaker, and the like are performed.

The special role election notifying means 25 informs a player under a certain condition when the special role is elected. The special role winning notification means 25 is composed of, for example, a lamp or the like, and this lamp is normally turned off. When the lamp is turned on, the special role winning notification is notified to the player. When a special combination is won, the game control unit 60 does not always notify the special combination winning notification unit 25 of the winning of the special combination, but determines whether or not to notify under a certain condition (for example, by lottery). To determine.

Further, the input side of the game control means 60 (FIG. 1)
(Central, left side) are electrically connected to the following peripheral devices. The start switch 41 indicates that the player
This is a switch operated when starting one rotation. The stop switches 42 are three switches that are independently arranged for each reel 31 and are operated by the player when the rotation of each reel 31 is stopped.

Next, an outline of a game in the slot machine 10 according to the present embodiment will be described. First, in a normal game, a player inserts a medal from a medal insertion slot (not shown) or operates a bet switch (not shown) for inserting a stored medal to change an activated line. Activate and turn on the start switch 41. Thereby, all the reels 31 are started. Then, the player stops the rotation of each reel 31 by pressing each stop switch 42. When the combination of the symbols on the reels 31 on the activated line matches a predetermined combination of symbols of any combination when all the reels 31 are stopped, the combination is awarded, and medals are paid out according to the established combination. Is performed.

When the player wins the BB, the game shifts from the normal game to the BB game. The BB game has a first mode game and a second mode game, and when the normal game is shifted to the BB game, the mode is first shifted to the first mode game. In the first mode game, only the lottery of the small role and the transition role for shifting to the second mode game are performed. Then, when the transfer role is won in the first mode game, B
The game shifts from the first mode game of the B game to the second mode game (bonus game).

In the second mode, a game in which a predetermined combination wins with a high probability is played for a prescribed number of times of winning or a prescribed number of games. In the second mode game, when the specified number of wins or the specified number of games has been reached, the game is returned to the first mode game again. Then, the first mode game and the second mode game are performed until the number of games of the first mode game reaches the specified number or the number of transitions from the first mode game to the second mode game reaches the specified number. repeat. When the number of transitions from the first mode game to the second mode game is the specified number, the BB game ends when the second mode game ends.

When an RB is won, the normal game is shifted to the RB game. In the RB game, one set of the second mode game (bonus game) in the above BB game,
In other words, a game in which the predetermined combination is won with a high probability is performed by the specified number of winnings or the specified number of games. Furthermore, S
When B wins, the game shifts from the normal game to the SB game. In the SB game, the game in which the predetermined combination in the second aspect game of the BB game or the RB game is won with a high probability is 1 game.
It is only a game. After the end of each special game, the game returns to the normal game in principle.

However, when the BB is won, it is determined by lottery whether the game after the end of the BB game is a normal game or a specific game. When it is decided to shift to a specific game, after the end of the BB game,
It shifts to a specific game instead of a normal game. Here, the specific game is a game in which the expected value of the number of obtained medals is larger than that in the normal game. When the game shifts to the specific game after the end of the BB game, in the present embodiment, the specific game is executed until the number of times reaches 100 which is set as the predetermined number of games, or BB.
Will be held until a prize is won. After the end of the specific game, the game returns to the normal game again.

First, the specific game in the present embodiment is as follows.
Replays are often won games. Therefore, the ratio of non-winnings decreases and the winning ratio of replays increases. As a result, even if the game is continued, the number of tokens possessed hardly decreases. Secondly, during a specific game, when a specific small win is won, the winning is notified to the player by the small win determination unit 24 described above. Therefore, the player can easily win the selected small winning combination. Thereby, it becomes possible to play a game while increasing the number of possessed medals.

Next, the game control means 60 will be described in more detail. The game control means 60 includes, as shown in FIG. Note that the following means in the present embodiment are exemplifications, and the game control means 60 is not limited to the means shown in the present embodiment. (Position Lottery Means) The role lottery means 61 performs lottery of a role (special role, small role, replay, etc.). Role lottery means 6
1 is, for example, a random number generating means (hard random number or the like) for a lottery lottery, a random number extracting means for extracting a random number generated by the random number generating means, and a winning of the role based on the random number value extracted by the random number extracting means. Determining means for determining the presence / absence of a winning combination and a winning combination.

The random number generation means of the combination lottery means 61 generates random numbers 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 determination unit determines the combination corresponding to the area to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with a lottery table 62 described later. For example, if the extracted random number value belongs to the special combination winning area, it is determined that the special combination has been won, and if it belongs to the non-winning area, it is determined that it has not been won. Note that, even after the special role is won, the role lottery means 61 performs at least one type of role other than the special role until the special role is won, particularly in the present embodiment, except for the special role during the normal game. Continue the lottery of all roles. Furthermore, during a specific game, when a BB is won during a specific game, the lottery means 61 continues the lottery of all the roles including the BB until the BB wins.

(Lottery Table) The lottery table 62 defines the winning probability of each role. In the present embodiment, the lottery table 62 includes a first lottery table 62a used during a normal game and a second lottery table 62a used during a specific game.
And a lottery table 62b. FIG. 2 shows the first lottery table 62a and the second lottery table 6 of the present embodiment.
It is a figure showing the winning probability of each role in 2b.

In FIG. 2, as described above, the role includes special roles BB and RB, specific small roles A to C, small roles of small roles 1 and 2, and replays. Is stipulated. The winning probability of the role is usually
It is determined for each number of inserted medals (1 to 3 medals) and for each set value of the payout rate, but is omitted in the present embodiment for convenience of explanation.

In the first lottery table 62a and the second lottery table 62b, the winning probability of the special role and various small roles is
They are set equal and only the replay winning probability is different. The replay winning probability is set to 1 / 7.3 (about 13.7%) in the first lottery table 62a, whereas it is set to 1 / 1.6 (6 in the second lottery table 62b).
2.5%), the first lottery table 62a
Is much higher than the replay winning probability.

Here, the probability of 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 of the first lottery table 62a is 1 / 1.49 (about 67%)
It is. On the other hand, the non-winning probability of the second lottery table 62b is 1 / 5.5 (about 18.2%). As a result, in the first lottery table 62a, the probability of non-winning has the highest value, but in the second lottery table 62b, the winning probability of replay is set higher than the non-winning probability.

Although not shown, the lottery table 6
2, a special game lottery table is provided in addition to the first lottery table 62a and the second lottery table 62b. For example, the lottery table for the BB game includes a first mode game lottery table and a second mode game lottery table. The first mode gaming lottery table is set so that various small wins and transition wins have a predetermined winning probability. The second mode gaming lottery table is determined so that the predetermined combination has a high winning probability.

Each lottery table 62 has a predetermined range of lottery areas, and the lottery areas are divided into a winning area and a non-winning area of each combination.
For example, the first lottery table 62a and the second lottery table 6
In 2b, the winning area of each winning combination in the lottery area is set to a predetermined ratio so as to have the winning probability shown in FIG.

Next, the inclination value of the lottery table 62 will be described. FIG. 3 shows the first lottery table 62a and the second lottery table.
It is a figure explaining the inclination value of lottery table 62b. Note that this inclination value is a value when the number of inserted medals is three, and is a value including the probability of winning a replay. As shown in FIG. 3, when the horizontal axis represents the number of games and the vertical axis represents the difference between the payout number and the insertion number of medals (difference number = payout number−insertion number), in a game that is not a special game, As the number of games increases, the difference number gradually decreases. The inclination value indicates the rate of decrease in the difference number. And
The inclination value of the second lottery table 62b is set higher than the inclination value of the first lottery table 62a.

The first lottery table 62a has a general inclination value that has been widely used, whereas the second lottery table 62b has an inclination value close to 100%. That is, when the second lottery table 62b is used, BB, RB and various small wins are won with a predetermined probability, and replays are frequently won (with a probability of 62.5%). Also, the number of owned medals is not reduced as compared with when the first lottery table 62a is used.

In the normal game, the lottery of the combination is performed by the combination lottery means 61 using the first lottery table 62a. As a result, during a normal game, medals decrease at a constant rate. On the other hand, in the specific game, the lottery of the role is performed by the role lottery means 61 using the second lottery table 62b. Thereby, during the specific game, the replay is frequently won.

Further, in the specific game, when one of the specific small wins A to C is won by the winning lottery means 61, the winning is notified to the player. On the other hand, in the normal game, even if the specific small combination is won, the winning of the specific small combination is not notified to the player. Therefore, in the normal game, the player cannot know the winning of the specific small role, and thus the specific small role won does not always win.
On the other hand, in the specific game, when the specific small role is won, the fact is notified, and the player can operate the stop switch 42 so that the selected specific small role wins.

As shown in FIG. 2, the probability that any one of the specific small wins A to C will be won is 3 / 19.5. For example, in the case where a game is played with three medals inserted, the number of medals to be paid out at the time of winning the special small roles A to C is 9
Assuming that the number of medals is one, the expected value of the number of medals acquired based on the specific small wins A to C in one game is 0.92. Further, the other small wins 1 and 2 are elected based on the probability shown in FIG. 2, and further, the replay is elected with a probability of 1 / 1.6.
The expected value of the number of obtained medals in one game when all the combinations are added exceeds 1. That is, as the number of games increases, the number of obtained medals also increases.

FIG. 4 is a view for explaining the inclination value in each game of the normal game and the specific game. Note that this inclination value is a value when the number of inserted medals is three, as in FIG. 3, and is a value including the probability of winning a replay. Further, in the specific game, when the winning rate of the specific small win that has been won is 100%, that is, when the specific small win is won, the player can operate the stop switch 42 to surely select the specific small win that has been won. This shows the case where a prize is won.

As shown in FIG. 4, when the number of games is plotted on the horizontal axis and the difference number is plotted on the vertical axis, in the normal game, as in the case of using the first lottery table 62a shown in FIG. As the number of times increases, the difference number gradually decreases. On the other hand, in the specific game, if the second lottery table 62b is used, the inclination value of the second lottery table 62b in FIG. 3 is at least obtained by using the second lottery table 62b. , With the increase in the number of games,
The difference number gradually increases.

As a result, even if the player is a beginner who can not win the specific small role that has been won in the specific game, the number of tokens possessed by the medal is reduced as shown by the inclination value of the second lottery table 62b in FIG. A game that hardly decreases can be played. Further, an advanced player who can surely win the selected small winning combination can play the game while increasing the number of tokens possessed as shown by the inclination value of the specific game in FIG.

The description returns to FIG. (Special role winning carry-over means, flag) The special role winning carry-over means 63 is a symbol of a special role in which a combination of symbols stopped on an active line after winning a special role in the lottery of the role by the role lottery means 61 is predetermined. In the game until it matches the combination of, that is, in the game until the special role is won,
The special role will be carried over.

Here, in the lottery drawing of the role by the role lottery means 61, if a small role (specific small roles A to C, small roles 1 to 2) or replay is won, the winning of the small role or the like is determined by the game. And the winning of the small role etc. will not be carried over after the next game. In other words, in a game that has been won as a small role, if the combination of the symbols of the small role that has been won stops on the active line, and if the small role does not win, the winning of the small role,
It becomes invalid at the end of the game.

On the other hand, when the special role is won, the winning of the special role is carried over after the next game until the special role is won. In the present embodiment, a flag 63a for determining whether or not a special combination has been won is provided. The flag 63a is turned on from off when the special lottery is won in the lottery drawing of the role by the lottery means 61,
The ON state is maintained until the special combination of symbols is stopped on the activated line, that is, until the special combination wins.

Further, in the present embodiment, during the specific game, even when the winning of BB is carried over by the special role winning carrying means 63, the role lottery means 61 continues the lottery of the role including BB. Here, conventionally, the special role was won,
During the game in which the winning of the special role is carried over, even if the random number value extracted temporarily belongs to the special role winning area in the lottery of the role by the role lottery means 61, it is determined that the special role is not won. I was Therefore, the special role did not win again.

However, in this embodiment, during the specific game,
BB is won in the lottery of the role by the role lottery means 61,
When the BB is won by the special role winning carry-over means 63 and the BB is won again in the lottery of the role by the lottery means 61, both the initially won BB and the BB won again are carried over. I do.

In response to the carryover of the BB winning,
A plurality of flags 63a for B winning are provided. That is, when the BB is won again during the carryover of the BB winning, the two BB winning flags 63a are turned on.
It should be noted that only one BB winning flag 63a may be provided, a counter corresponding to the flag 63a may be provided, and the counter value may be added when the BB is won again during the carryover of the BB winning.

When a plurality of BBs are won by the special role winning carry-over means 63, the BB
When the symbol combination stops at the activated line, the carryover of the winning of one BB is released. For example, when the winning combination of two BBs is carried over by the special role winning carrying means 63, and when the combination of the BB symbols stops on the active line, that is, when the BB is won, the winning of one BB is carried over. Is released, and the carryover of the winning of the other one BB is maintained.

(Reel Stop Control Unit) The reel stop control unit 64 is in a game state (normal game state, special game state, etc.).
And the lottery result of the role lottery means 61 and the stop switch 4
The stop position of the reel 31 is determined with reference to a stop position determination table 65 described later, based on the timing at which the reel 31 is turned on, and the reel 31 is placed at the determined position.
Is stopped. Reel stop control means 64
The reel 31 is determined by a predetermined stop position determination table 65.
Is determined, the drive of the motor 32 is controlled to control the reel 31 to stop at the determined position.

(Stop Position Decision Table) The stop position decision table 65 includes a lottery result of the role by the lottery means 61,
The stop position of the reel 31 is determined from the position and the like of the reel 31 at the moment when the stop switch 42 is operated, and three reels are provided in the present embodiment. First, during the normal game and the specific game, the stop position determination table 65 used as the stop position determination table 65 used when the special lottery is not won in the lottery of the role by the role lottery means 61.
a is provided.

A stop position determination table 65b is provided as a stop position determination table 65 used when a special combination is won in the lottery of the role by the role lottery means 61 during a normal game. Further, during a specific game, a stop position determination table 65 used when a special combination is won in the combination lottery by the combination lottery means 61.
A stop position determination table 65c is provided.

FIG. 5 is a diagram showing a stop position determination table 65a to a stop position determination table 65c. In FIG. 5, “special role non-winning control” means a stop switch 42.
Based on the operation timing, the stop position of the reel 31 is determined so that the special combination of symbols does not stop on the activated line (so that the special combination does not win). On the other hand, “special role winning control” means that the stop switch 4
Based on the operation timing of No. 2, the special combination of symbols is stopped on the activated line as much as possible within the possible range of the stop control of the reel 31 (so that the special combination wins).
The stop position of the reel 31 is determined.

The "losing eye" is a combination of symbols meaning that there is no possibility of winning a special role (the degree of expectation of winning is 0) or that the degree of expecting a special role is low. Further, the “chance chance” is a combination of symbols that means that the special role has the possibility of winning the special role more than the loss factor, but does not necessarily mean that the special role has been won.
Furthermore, the “reach eye” means a combination of symbols that means that the special role has been won, that is, the finalization of the special role.

First, in FIG. 5 (a), the stop position of the reel 31 is determined in the stop position determination table 65a so that the special role does not win, and the reel 31
At the time of stopping, a loss eye or a chance eye appears. The rate at which the losing eyes and the chance eyes appear,
They are set to be approximately equivalent.

In FIG. 5B, the stop position determination table 65b sets the stop position of the reel 31 so that the special role can win as much as possible. It makes the eyes appear. The ratio of the appearance of the chance eyes and the reach eyes is set somewhat higher for the reach eyes.

Further, in FIG. 5 (c), in the stop position determination table 65c, most of the stop positions of the reel 31 are determined so that the special combination does not win, and the stop position of the reel 31 is determined when the reel 31 stops. It is determined that a chance eye will appear. And slightly (several%
Degree), reels 31 so that special roles can be won as much as possible.
Are determined, and a chance is displayed when the reel 31 stops.

The above stop position determination table 65a
In steps 65 to 65c, when the role lottery means 61 wins a role other than the special role, the stop position of the reel 31 is determined so that the winning role is preferentially won.

(Special game execution means) Special game execution means 6
6 is a special lottery (BB, RB or SB) by the lottery means 61
And the special combination of symbols is stopped on the activated line and a prize is won, the normal game is changed to the special game (BB
Game, RB game, or SB game) to perform a special game. The special game execution means 66,
At the time of shifting to the special game, control is performed so as to perform various effects in order to notify the player that the game is to be shifted to the special game.

During the special game, the special game executing means 6
Numeral 6 controls the progress of the game during the special game. For example,
Means for counting the number of wins of the predetermined combination in the second mode game in the BB game, the number of games for the first mode game and the second mode game, and the means for counting the number of transitions from the first mode game to the second mode game Means for determining whether or not the special game end condition is satisfied, and means for controlling to end the special game when it is determined that the special game end condition is satisfied.

(Game Mode Determining Means) Game Mode Determining Unit 6
Reference numeral 7 determines whether the game after the end of the special game (particularly, the BB game in the present embodiment) is a normal game or a specific game. As the game mode determination unit 67, a random number generation unit or the like similar to that described in the combination lottery unit 61 is used. Then, at the time of winning the BB, the game mode determining means 67
The random number generated by the random number generating means is extracted, and based on the random number value, it is determined to be a normal game or a specific game. In the present embodiment, the normal game or the specific game is determined with a probability of 1/2 each.

Therefore, in the random number generation means of the game mode determination means 67, for example, 0 to 65535 in decimal system
Is generated, the extracted random number value is 0 to
When it is in the range of 32767, it is determined to be a normal game, and when the extracted random number is in the range of 32768 to 65535, it is determined to be a specific game. This determination may be made any time after the BB is won by the role lottery means 61 and immediately before the start of the first game after the end of the BB game.

Further, it is also possible to determine the game mode by the game mode determining unit 67 together with the lottery by the role selecting unit 61. For example, in the lottery table 62 of the role lottery means 61, the BB winning area may be divided into two areas, one area being an area determined to be a normal game, and the other being an area determined to be a specific game.

(Specific game execution means) Specific game execution means 6
8 is a transition to a specific game after the end of the BB game, when a predetermined condition is satisfied, in particular, in this embodiment, when the BB is won and the game mode determination means 67 decides to perform the specific game. And a specific game is performed. In the present embodiment, the termination condition of the specific game is when the number of games reaches 100 or when a BB is won. Therefore, only winning the BB in the lottery of the role by the role lottery means 61 does not end the specific game,
The specific game is continued until the BB wins. Also, RB
, The specific game is interrupted and the game is shifted to the normal game, and if the RB is won in the normal game, the game is shifted to the RB game. Then, after the end of the RB game, the process returns to the specific game again and the continuation of the specific game is performed.

The specific game execution means 68 includes the following means. (Specific game number counting means) The specific game number counting means 68a counts the number of games in the specific game when shifting to the specific game after the end of the BB game, and a counter or the like is used. Is done. The reason why the number of times of the specific game is counted is that the upper limit is set for the number of times of the specific game. In the present embodiment, when the number of games has been counted 100 times by the number-of-games-in-specific-game counting means 68a, the specific game is finished and the normal game is returned.

(Small Role Winning Notification Control Means) The small role winning notification controlling means 68b wins when a small win, particularly any of the specific small wins A to C in the present embodiment, is won during a specific game. The control is performed so as to notify the specific small combination to the player. The small role winning notification control means 68b controls to notify immediately after the start switch 41 is turned on. This is for the following reason.

When a specific small winning combination is won, the winning is valid only in the game concerned, and the winning is set so as not to be carried over to the next game. In other words,
If the particular small role does not win in the game that was won by the particular small role, the winning right generated by the winning will also be extinguished.
For this reason, when the specific small win is won, the notification is made before the stop switch 42 is turned on so that the player can win the specific small win.

Further, the notification of the particular small win which has been won by the small win win notification control means 68b is performed by the small win win notification means 24 shown in FIG. In addition, the winning is notified in a different manner for each of the specific small wins A to C, for example, by displaying different images. This is because, if the player is notified in a different manner for each of the selected specific small wins A to C, the player can determine the type of the winning specific small win.

(Special Role Winning Restriction Means) The special role winning restriction means 68c wins the special role by the lottery of the role by the role lottery means 61 when the specific game is executed by the specific game execution means 68. Sometimes, control is performed so that the special combination does not win, or control is performed so that the special combination is less likely to win than during the normal game.

In the present embodiment, the special role winning restriction means 68c controls the BB not to win only when the BB is won, or controls the BB to be harder to win than in the normal game. When the RB is won, such control is not performed. This is because, as described above, when the RB is won, the specific game is interrupted and the normal game is started.

When the BB is won during the specific game, the special role winning restriction means 68c uses the stop position determination table 65c as the stop position determination table 65 to be used until the winning. As a result, winning of BB is restricted. That is, when the stop position determination table 65c is used, BB does not win in most cases, as described above. Thereby, even when, for example, the BB is won immediately after the specific game is started, the specific game can be continued to some extent. Therefore, it is easy to obtain the expected number of medals by shifting to the specific game.

Further, when the player wins the BB during the specific game, the control for restricting the winning of the BB is performed to facilitate the continuation of the specific game. Therefore, the chance of winning the BB may be reduced. However, in this embodiment, when the BB is won during the specific game, the flag 63a is turned on,
Until the BB wins, lottery selections including the BB are performed. For this reason, after winning the BB, the player may win the BB again while continuing the specific game. Then, when the player wins the BB again, the flag 63a is turned on based on the winning, and the winning of a plurality of BBs is carried over, so that there is no disadvantage to the player.

(Special Role Winning Information Canceling Means) The special role winning information stopping means 68d wins BB by the lottery of the role by the role lottery means 61 when the specific game is executed by the specific game executing means 68. If it is, the notification of BB by the special role winning notification means 25 is stopped. This control is performed for the following reason. During the specific game, control is performed so that the BB does not easily win even when the BB is won. As a result, during the specific game, the player
It becomes difficult to determine whether or not B has been won. But,
This is because if the special role election informing means 25 notifies that the player has won the BB, the player will know that the player has won the BB.

Next, the flow of a game in the present embodiment will be described based on a flowchart. FIG. 6 is a flowchart showing a flow from the transition from the normal game to the BB game to the return to the normal game or the transition to the specific game.
First, the player inserts a medal to activate the activated line, and turns on the start switch 41. Thereby, each reel 31 starts. In step S1, the game control means 60 continues to detect whether or not the start switch 41 has been turned on. If ON is detected, the process proceeds to the next step S2, where the lottery by the lottery means 61 is performed. Lottery table 62 used in this role lottery
Is a first lottery table 62a.

In the next step S3, the special role BB
Is determined whether or not has been won. If it is determined that has been won, the process proceeds to step S4, the game mode determination means 67
Whether the game after the end of the BB game is a normal game or a specific game is determined by lottery. And
Proceed to step S5. On the other hand, when it is determined in step S3 that BB has not been won, the process proceeds to step S5.

In step S5, the game control means 60
Whether or not the stop switch 42 is turned on is continuously detected based on an output signal from the stop switch 42. If ON is detected, the process proceeds to step S6, where the reel stop control means 64 determines a predetermined stop position determination table 65 from the result of the lottery of the role by the role lottery means 61 and the timing when the stop switch 42 is turned on. , The stop position of the reel 31 is determined, and the reel 3 is positioned at the determined position.
1 is controlled to stop.

In the next step S7, it is determined whether or not all the reels 31 have stopped. If all the reels 31 have not yet stopped, the flow returns to step S5, and if they have stopped, the flow proceeds to step S8. In step S8, the game control means 60
Determines whether the combination of BB symbols has stopped on the activated line, that is, whether the BB has won. When it is determined that BB has won, the process proceeds to step S9.

On the other hand, if it is determined in step S8 that BB has not won, the process proceeds to "A" in the figure. "A" in the figure
After advancing to step S1, if no winning is made, the process returns to step S1 without performing any winning processing. When a small winning combination is won, the process returns to step S1 after performing predetermined processing such as payout of medals.
Furthermore, at the time of winning a replay, after automatically inserting the number of medals inserted in the game, the process returns to step S1.
Note that when the RB wins, the game shifts to the RB game, but the description is omitted here.

In the step S9, the special game execution means 66
Shifts the normal game to the BB game and starts the BB game. Then, in the next step S10, the special game execution means 66 continues to determine whether or not the end condition of the BB game is satisfied, and when it is determined that the condition is satisfied, the process proceeds to step S11. In step S11, the game control means 60
Determines whether a specific game has been determined by the lottery in step S4. When a specific game is decided,
Proceeding to step S12, the specific game execution means 68 controls to shift to the specific game. On the other hand, when it is not determined to be the specific game, the process proceeds to step S13 to control to shift to the normal game.

FIG. 7 and FIG. 8 are flow charts showing the flow of a game when a transition is made to a specific game. FIG. 8 is a flowchart following FIG. Step S12 in FIG.
When the process proceeds to step S21, the process proceeds to step S21 and subsequent steps in FIG. First, when a specific game is started in FIG.
8a initializes (G = 0) the number of games G in a specific game.

Then, in the next step S22, the game control means 60 continues to detect whether or not the start switch 41 has been turned on. When ON is detected, the process proceeds to the next step S23, and the lottery by the lottery means 61 is performed. In step S23, a lottery of a winning combination is performed using the second lottery table 62b. Further, even when the player has already won the BB, the lottery including the BB is performed.

In the next step S24, the game control means 6
0 determines whether or not the BB has been won. If it is determined that the BB has been won, the process proceeds to step S25, where the special role winning restriction means 68c of the specific game execution means 68 sets the stop position determination table 65c. Select On the other hand, if it is determined in step S24 that BB has not been won, the process proceeds to step S26, where the specific game execution means 68 selects the stop position determination table 65a.

In the step S27, the game control means 60
Keeps detecting whether or not the stop switch 42 is turned on by the output signal from the stop switch 42. When ON is detected, the process proceeds to step S28, where the reel stop control unit 64 selects the combination in step S25 or S26 from the result of the lottery of the combination by the combination lottery unit 61 and the timing when the stop switch 42 is turned on. The first or third stop position determination table 65a or 65
The stop position of the reel 31 is determined with reference to c, and the stop control of the reel 31 is performed at the determined position.

In the next step S29, it is determined whether or not all the reels 31 have stopped. If all the reels 31 have not yet stopped, the flow returns to step S27, and if they have stopped, the flow proceeds to step S30 in FIG. In step S30, the game control means 60 determines whether or not the combination of BB symbols has stopped on the activated line, that is, whether or not BB has won. If it is determined that BB has won, the process proceeds to step S
35, the specific game is completed, and the special game execution means 66
Shifts to the BB game.

If it is determined in step S30 that the BB has not won, the process proceeds to step S31, and it is determined whether or not a small role has been won. When it is determined that the small combination has won, the process proceeds to step S32, and processing such as payout according to the winning combination is performed. Specifically, when a small winning combination is won, a payout process of the number of medals according to the small winning combination is performed. At the time of winning a replay, a process of automatically inserting the number of medals inserted in the game is performed. Then, the process proceeds to step S33. On the other hand, if it is determined in step S31 that no winning combination has been won, the process proceeds to step S33 without performing the process of step S32.

In step S33, the specific game number-of-games counting means 68a adds 1 to the number of games G. Then, in the next step S34, the specific game execution means 68
Means that the number of games G is a prescribed number (100 in this embodiment)
Is determined. When it is determined that the predetermined number of times has been reached, the process proceeds to step S35, where the specific game is ended, and the process shifts to the normal game. On the other hand, when it is determined in step S34 that the number of games G has not reached the specified number, the process returns to step S22 to continue the specific game.

Although not shown in the above flow chart, when a BB is won, the special role winning carry-over means 63 turns on the flag 63a. And
If the BB is won again before the BB wins, two flags 63a are turned on. Further, when the particular small combination is won in the lottery drawing in step S23, the small combination winning notification control means 68b notifies the small combination winning notification means 24 of the winning of the specific small combination.

Further, when the BB is won in the lottery of the winning combinations in step S23, the special role winning notification canceling means 68d stops the special role winning notifying means 25 from reporting the BB winning. Further, when the player wins the RB in the lottery of the winning combination in step S23, the specific game is temporarily interrupted and the game is shifted to the normal game. And R in the normal game
When B wins, the game shifts to the RB game. When this RB game is over, the process returns to step S22 again to continue the specific game. At this time, the number of games of the specific game inherits the number of games before the interruption of the specific game.

If the BB is won during the specific game, but the BB does not win during the specific game, after the specific game is completed, the following is performed. First, the special role winning notification means 2 which has been canceled by the special role winning notification canceling means 68d.
The notification of the winning of BB by 5 is released. And when the notification by the special role winning notification means 25 is performed unconditionally,
In the first game, the special role winning notification means 25 notifies the BB winning. On the other hand, when an effect pattern is selected by a lottery or the like, and the special role winning notification means 25 notifies the BB winning according to the effect pattern, the special role winning is notified according to the effect pattern.

When the game is shifted from the specific game to the normal game with the BB being won, the game control means 60
The stop position determination table 65b is selected, and the reel stop control means 64 performs stop control of the reel 31 using the stop position determination table 65b. As a result, the reel 31 is stopped as much as possible so that the BB wins, and a reach or a chance appears when the BB does not win.

Further, when a plurality of BBs are won during a specific game, if the BB wins first, 1
The carryover of the election of one BB is released, and the carryover of the election of the other BB is maintained. As a result, even when the normal game is shifted to the BB game, and the BB game ends and returns to the normal game again, the winning state of the BB is carried over by the special role winning carrying means 63. So, in this case,
The stop position determination table 65b is selected from the beginning of the normal game, and the BB can be won again.

Here, if the winning of a plurality of BBs is carried over after the end of the specific game, it is also possible to give a further privilege to the player. For example, when all BBs carried over have won a prize and these BB games have ended, the game may be shifted to a specific game without fail.
In addition, when winning in a BB, if the winning of another BB is carried over, the carry over of the winning of all BBs is released, and the first mode game of the BB game is performed in the same manner as during the specific game. Alternatively, the gaming state may be such that the winning of the specific small role is notified. Thereby, in the first mode game of the BB game, the player can win a prize according to the skill of the player without missing the specific small winning combination. Therefore, the player can acquire more medals.

(Second Embodiment) Next, a second embodiment of the present invention will be described. In the second embodiment, the stop position determination table 65 is different. In the second embodiment, the stop position determination table 65 has four tables when the special role is not elected.
And four at the time of winning the special role. FIG. 9 is a diagram showing the stop position determination table 65. In FIG. 9, (a) shows four stop position determination tables 65d to 65g selected in the game when the special role is not won.
Is shown. (B) shows four stop position determination tables 65h to 65k selected in a game at the time of winning a special combination.

In FIG. 15A, the stop position determination tables 65d to 65f are used to cause a loss to appear when the reel 31 stops. Three patterns are provided as losing eyes, and the patterns are classified into the three patterns to form the stop position determination tables 65d to 65f.
The stop position determination table 65g is for causing a chance to appear when the reel 31 stops. Furthermore, these stop position determination tables 65d to 65g are designed to prevent the special combination of symbols from stopping on the active line based on the special combination non-winning control, that is, the operation timing of the stop switch 42 (the special combination does not win). Thus, the stop position of the reel 31 is determined.

On the other hand, in (b) of the drawing, the stop position determination table 65h is for causing a chance to appear, similarly to the stop position determination table 65g selected in the above-mentioned game when the special role is not won. is there. Further, the stop position determination tables 65i to 65k are to make the reach appear when the reel 31 stops. In addition, the stop position determination tables 65i to 65k indicate special combination winning control, that is, based on the operation timing of the stop switch 42, within the possible range of the stop control of the reel 31, the combination of symbols of the special combination is set to an effective line as much as possible. The stop position of the reel 31 is determined so as to stop (so that the special combination wins).

On the other hand, the stop position determination table 65h
Is a special role winning limit control, that is, the reel 31 is set so that BB is difficult to win (so that the winning rate of BB is low).
The stop position is determined. Here, when any of the winning combinations is won in the lottery in the slot machine 10 and the symbol related to the winning combination does not stop on the activated line at the position where the ON of the stop switch 42 is detected, the reel 31 is used. By controlling the movement at the time of stop, the symbol relating to the winning combination is actively stopped on the activated line, thereby increasing the winning probability of the winning combination.
The stop control of the reel 31 is usually set within five symbols from the position where the stop switch 42 is detected to be on.

Here, the stop position determination tables 65i to 65i
5k is such that when there is a symbol constituting a special combination in a symbol up to 5 symbols before counting from the position where the stop switch 42 is detected to be on, the symbol composing the special combination is stopped on the activated line. , The stop position of the reel 31 is determined.

On the other hand, the stop position determination table 65h
When there is a symbol constituting a special combination in the symbol up to two symbols before counting from the position where the ON of the stop switch 42 is detected, so that the symbol composing the special combination stops on the activated line, The stop position of the reel 31 is determined. That is, the stop position determination table 65i used in the special role election is another stop position determination table 65i.
Reel 3 until reel 31 stops for up to 65k
By reducing the movable amount of 1, control is performed to make it difficult for the special role to win.

In the second embodiment, a stop position determination table selecting means is provided. The stop position determination table selecting means,
One of the stop position determination tables 65 is selected based on the gaming state (normal gaming state, specific gaming state) and whether or not the special lottery has been won by the lottery drawing by the lottery means 61.

First, in the normal game, when the special role is not won, the stop position determining table selecting means selects one of the stop position determining tables 65d to 65g. As a selection method, for example, a lottery method using random numbers can be used. In addition, in the normal game, in the game at the time of winning the special role, the stop position determination table selecting means,
Stop position determination table 65h, 65i, 65j or 65
Select one of k.

Further, in the game when the special role is not elected in the specific game, similarly to the game when the special role is not elected in the normal game, the stop position determining table selecting means selects one of the stop position determining tables 65d to 65g. Or choose.

On the other hand, in a game in which a BB is won in a specific game, the stop position determination table 65h is always selected. As a result, in the game that has been won as the BB of the specific game, only the chance eyes appear and the reach eyes do not appear. Therefore, it becomes difficult for the player to determine whether or not the player has won BB during the specific game. Furthermore, in the game that has been won as the BB of the specific game, if there is no symbol constituting the BB in the symbols up to two symbols before counting from the position where the stop switch 42 is detected to be turned on, the BB does not win. Become. Therefore,
BB becomes difficult to win.

FIG. 10 is a flowchart showing the processing of the stop position determination table selecting means in the second embodiment. First, when the lottery of the combination is performed by the combination lottery means 61 in step S41, in the next step S42, the stop position determination table selecting means determines whether or not the BB is won based on the ON / OFF of the flag 63a. Determine.
If it is determined that BB has been won, step S43
If it is determined that BB has not been won, the process proceeds to step S46. In step S43, the stop position determination table selecting means determines whether or not the game is a specific game. When it is determined that the game is the specific game, the process proceeds to step S45, and when it is determined that the game is not the specific game (it is the normal game), the process proceeds to step S44.

In step S44, the stop position determination table selecting means selects the stop position determination tables 65h, 65i,
One of the stop position determination tables 65 is selected from 65j or 65k by lottery or the like. Step S4
In 5, the stop position determination table selecting means selects the stop position determination table 65h. Step S
In 46, the stop position determination table selecting means selects one of the stop position determination tables 65 from the stop position determination tables 65d to 65g by lottery or the like.

When one of the stop position determination tables 65 is selected in step S44, step S45, or step S46, the flow advances to step S47. And
In step S47, the reel stop control means 64 determines the reel 3 based on the selected stop position determination table 65.
1 is performed.

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 for example, the following various modifications are possible. (1) In the present embodiment, the specific game is a game in which the probability of winning in replay is higher than that in a normal game, and when a specific small role is won, the winning is notified.

For example, if the specific game is a game in which the probability of winning a replay is higher than that in a normal game (a game in which the winning of a small role is not reported), the number of medals hardly decreases during the specific game, in other words, the number of medals is currently The game can be continued while being maintained. Then, in this state, it is possible to wait for the winning of the special role.

Here, when the special role is won during the specific game, it is more advantageous to shift to the special game in such a way that the special role is won immediately, rather than continuing the specific game in which the medal does not decrease. You might also say that. However, in this specific game, while giving the special role the opportunity to win multiple times,
If the special role is won a plurality of times, the plurality of wins may be carried over. As a result, it is possible to expect a plurality of special combinations to be won in a gaming state in which medals do not decrease.

Further, if the specific game is a game for notifying the winning when the specific small role is won (the replay winning probability is the same as the normal game), the winning probability of the specific small role and the payout number can be adjusted. Alternatively, the game state may be a game state in which medals hardly decrease, or a game state in which medals slightly increase, or a game state in which medals increase at a predetermined rate.

Further, the specific game may be a game in which the player can arbitrarily win a specific small role by operating the stop switch 42. In this case, for example, a specified value is set for the number of games of the specific game and the net increase in the number of medals during the specific game. Then, when the player shifts to the specific game, the player can win the medal to near the specified value by winning the specific small combination. Further thereafter, the player can continue the specific game until the number of games reaches the specified value by adjusting the winning and the non-winning of the specific small role. Then, during the specific game, it is possible to expect a special role to be won. As described above, the specific game in the present invention may be a game of any mode as long as the expected value of the number of obtained medals is larger than that of the normal game.

(3) In the present embodiment, the specific reel stop position determination table 65 selected when the special combination is won during the specific game is provided. However, the present invention is not limited to this. Alternatively, the stop control of the reel 31 may be performed without using. For example, when the stop switch 42 is turned on, it is possible to search for a stoppable position of the reel 31 and perform stop control for determining an appropriate stop position within the range of the stoppable position.

(4) In the present embodiment, during the specific game, BB
, The winning of a plurality of BBs is carried over, but this is optional. Further, it is possible to arbitrarily set what kind of game to shift to when a plurality of BBs are won. For example, when the winning of a plurality of BBs is carried over, after the specific game ends, the game may be shifted to the BB game continuously plural times. Alternatively, after the end of the specific game, the game may be shifted to a more advantageous BB game than a general BB game.

(5) In the present embodiment, during the specific game, the RB
When a winner is selected, the specific game is interrupted and the game is shifted to the normal game. However, the present invention is not limited to this, and the RB winning may be carried over similarly to the BB winning.
Further, similarly to the BB winning control, it is also possible to perform control so as not to win the RB or to make it difficult to win.
