Description

  The present invention executes a special game on the condition that the special combination is won and the combination of symbols of the special combination stops on the active line, and when a predetermined condition is satisfied, a specific game different from the special game is played. It relates to the slot machine to be executed.

In a conventional slot machine, when a special role is won in a lottery of a normal game and the combination of symbols of the special role stops on the active line, that is, when the special role wins, the game is shifted from the normal game to the special game. ing.
The special game is a game that has a larger expected medal number than the normal game and is advantageous to the player.

Here, BB (Big Bonus) game, RB (Regular Bonus) game, etc. are known as special games.
In these special games, the upper limit number of games is determined in advance. Therefore, the player aims to acquire more medals by making the maximum number of winning games as much as possible by using the maximum number of special games.

  However, according to the above-mentioned conventional technology, first, most of today's slot machines are provided with special roles and can be shifted to special games. There was a problem of becoming something.

  Second, during special games, it is more advantageous to stop the reels at an appropriate position to increase the winning rate of the winning combination. However, among players who have a certain level of skill, the winning rate of the winning combination Since there was not much difference, there was a problem that there was almost no difference in the number of medals earned during special games. Therefore, the only difference between the players was how many times the special role (especially BB) was won.

  Therefore, the problem to be solved by the present invention is to execute a specific game which is a game different from the special game and has a larger expected medal number than the normal game. Then, the profit peculiar to the specific game is changed to give the player a sense of expectation and tension, and to make a difference in the number of medals obtained among the players.

The present invention solves the above-described problems by the following means.
(Claim 1)

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram showing an outline of a first embodiment of a slot machine according to the present invention.
The game control means 60 of the slot machine 10 is a means for comprehensively controlling the entire slot machine 10 including the progress and effects of the game of the slot machine 10. The game control means 60 includes a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and data that is captured when the CPU performs various controls. RAM and the like that are temporarily stored.

A motor 32 is electrically connected to the output side (right side in FIG. 1) of the game control means 60.
The motor 32 is for rotating the reel 31, is connected to the center of rotation of the reel 31, and is controlled by the game control means 60.

The reel 31 has a ring shape, and a reel tape on which a plurality of types of symbols (such as symbols constituting a winning combination) are printed is attached to the outer peripheral surface thereof. One reel 31 is provided with, for example, 21 symbols at equal intervals. In the present embodiment, three reels 31 are provided in parallel. Each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from a display window (not shown) provided on the front panel of the slot machine 10. Therefore, nine symbols are arranged so that a total of nine symbols can be seen from the display window of the slot machine 10.
When the reel 31 is rotated by the motor 32, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window at a predetermined speed.

Further, the following peripheral devices that are operated by the player during the game are electrically connected to the input side (left side in FIG. 1) of the game control means 60.
The medal sensor 22 is a sensor that detects a medal inserted from the medal insertion slot 21.
The bet switch 23 is a switch operated when the player inserts a medal within the credit range.

The start switch 41 is a switch that is operated when the player starts the rotation of the reel 31.
Three stop switches 42 are provided independently for each reel 31 and are operated when a player stops the rotation of each reel 31.

FIG. 2 is a diagram illustrating each combination, the number of medals to be paid out, and the winning probability of the probability table 62 (described later) in the first embodiment.
The combination includes a special combination BB (Big Bonus) and RB (Regular Bonus), four kinds of small combinations 1 to 4, and a replay (re-playing combination). When all the reels 31 are stopped, when the combination of symbols stopped on the active line matches the combination of symbols of a predetermined role, a winning combination of that symbol is won, and a predetermined number of medals are paid out for each symbol. It is.

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

The three symbols that are continuous from top to bottom of the reel 31 that can be seen from each display window are located on three effective lines in the upper, middle, and lower stages in the horizontal direction.
Also, this valid line is validated according to the number of inserted medals. If one medal is inserted, one effective line in the middle in the horizontal direction is activated. If it is two, three effective lines in the horizontal direction are activated. If three, all five effective lines are activated. The

Among the above-mentioned roles, BB and RB are roles for shifting from a normal game to a BB game and an RB game (games that are advantageous to the player), which are special games, respectively. For example, when all the reels 31 are stopped and the combination of symbols on the active line is “7”-“7”-“7”, a BB win is won, 15 medals are paid out, and the BB game Migrate to
In addition, although description is abbreviate | omitted in this embodiment, you may provide SB (single bonus) as another special role. When the SB wins, the game shifts from the normal game to the SB game.
After each special game is over, the game returns to the normal game.

A small combination is a combination in which a predetermined number of medals are paid out. The small combination in the first embodiment includes a specific small combination 1, small combinations 2 and 3, and a specific game generation small combination 4.
The small roles 2 and 3 are combinations in which eight or two medals are paid out by winning each.

  The specified small combination 1 is a combination in which 15 medals are paid out by winning. Here, the specified small role 1 is not necessarily a winning by just winning, but a winning only when the stop switch 42 is operated in a specific operation order. And during the normal game, since the specific operation order is not notified, even if winning is not always won. On the other hand, when the specific small combination 1 is won during the specific game, the operation order of the stop switch 42 for winning the specific small combination 1 is notified. Therefore, when the stop switch 42 is operated in the notified operation order, the specific small combination 1 always wins.

Further, the specific game occurrence small combination 4 is a combination in which three medals are paid out by winning. Furthermore, by winning the specific game occurrence small role 4, it is a role that can be transferred to the specific game. When the specific game occurrence small role 4 is won during the normal game, it is possible to shift from the normal game to the specific game. In addition, when the specific game occurrence small role 4 is won during the specific game, an opportunity to increase the number of games of the specific game is given.
Furthermore, the replay is a replaying role in which the number of medals inserted in the game is automatically inserted and the replaying can be performed.

The following peripheral devices for outputting effects during the game are electrically connected to the output side (right side in FIG. 1) of the game control means 60.
The lamp 33 is fixedly disposed on the inner peripheral side of each reel 31 and illuminates the design of the reel 31 in the display window from behind. The lamp 33 outputs an effect of emitting light in a specific pattern in addition to making the design easy to see.

The speaker 34 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
The image display device 35 includes a liquid crystal display, a dot display, and the like, and displays various effect images and the like.

Further, the image display device 35 notifies the operation order of the stop switch 42 for winning the specific small combination 1 when the specific small combination 1 is won during the specific game, which will be described later. To do.
Further, the image display device 35 also serves as a specific game number display means, which will be described later.

Next, the game control means 60 will be described in more detail.
As shown in FIG. 1, the game control means 60 includes the following means. The following means in the present embodiment are examples, and the game control means 60 is not limited to the means shown in the present embodiment.

(Role lottery means)
The role lottery means 61 performs a lottery for a role. The role lottery means 61 is based on, for example, a random number generator for hard lottery (hard random number, etc.), a random number extractor for extracting a random number generated by the random number generator, and a random value extracted by the random number extractor. Determination means for determining whether or not a winning combination has been won and a winning combination.

  The random number generation means of the role lottery means 61 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). 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 region to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with a probability table 62 described later. For example, when the extracted random number value belongs to the special combination winning area, it is determined that the special combination is won, and when it belongs to the non-winning area, it is determined to be non-winning.

(Probability table)
As shown in FIG. 2, the probability table 62 defines the winning probabilities of the respective combinations. In addition, although the winning probability of a combination is usually determined for each number of inserted medals (1 to 3) and for each set value of the payout rate, it is omitted in this embodiment.

  The probability table 62 has a lottery area in a predetermined range, and the lottery area is divided into a winning area and a non-winning area for each combination. The winning area of each combination 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.

(Means to carry over special roles)
The special combination winning carry-over means 63 matches the combination of symbols of the special combination set in advance after the special combination (BB or RB) is won in the drawing of the combination by the combination lottering means 61 and then stopped on the active line. In the game up to, that is, the game until the special role is won, the special role winning is carried over.

  Here, in the lottery of the role lottery means 61, when winning a small role or replay, the winning of the small role is valid only in the game, and after the next game, the winning of the small role, etc. Is not carried over. In other words, in a game won for a small role etc., if the combination of symbols of the selected small role, etc. stops on the active line and the small role does not win, the winning of the small role will be awarded at the end of the game It becomes invalid.

On the other hand, when a special role is won, the winning of the special role is carried over after the next game until the special role is won.
Further, even in a game in which the winning of the special role is carried over by the special role winning carry-over means 63, the role lottery means 61 continues the lottery of the role including the special role.

  Here, during a game in which a special role is won and the special role is being carried over, even if the random number extracted by the role lottery means 61 is in the special role winning area, What is known not to be determined to be a special role win. In this case, the special role will not be won again. However, in the present embodiment, the role lottery means 61 performs the lottery of the role including the special role even after the special role is won. As a result, special roles may be won multiple times.

  In the present embodiment, a special role is won in the lottery of the role by the role lottery means 61 during a game in which a special role is won in the lottery of the role lottery means 61 and the special role winning means 63 is carried over. When the team is elected again, it will carry over the special roles won so far and the special roles won again. For example, when winning the BB first and then winning the RB, the winning of both the first winning BB and the next winning RB is carried over. The same applies to the reverse case. In addition, after winning the BB, if the BB is won again before winning the BB, the two BBs will be carried over. The same applies when two RBs are won.

(Special role winning counter)
The special role winning number counter 64 is for counting the number of times that the special role is won in order to cope with the carry-over of a plurality of winning points of the special role described above. The special role winning number counter 64 of this embodiment includes a BB winning number counter 64a that counts the number of BB winning times, and an RB winning number counter 64b that counts the number of RB winning times. When BB or RB is won, 1 is added to the count value of the BB winning number counter 64a or the RB winning number counter 64b, respectively. The special role winning counter 64 is a 1-byte counter in the present embodiment, and is constituted by a RAM.

  When the number of winnings of one or more special roles is counted by the special role winning number counter 64, when the combination of symbols of the special role stops on the active line, the special role related to the combination of symbols stopped on the active line The count value of the number of winnings is subtracted by 1. For example, when the number of wins is counted as 2 by the BB win count counter 64a and the number of wins of the RB is counted as 1 by the RB win count counter 64b, the combination of symbols of BB stops on the active line The number of winning times by the BB winning number counter 64a is subtracted to 1. In this case, the number of winning times by the RB winning number counter 64b is maintained at 1.

(Reel stop control means)
The reel stop control means 65 determines the reel based on the gaming state (for example, the normal gaming state, the special gaming state, and the specific gaming state), the lottery result of the combination lottery means 61, the timing when the stop switch 42 is turned on, and the like. The stop position of the reel 31 is determined with reference to the stop control table 65a, and the motor 32 is driven and controlled so that the reel 31 stops at the determined position.

  The reel stop control table 65a determines the stop position of the reel 31 from the lottery result of the combination by the combination lottery means 61 and the position of the reel 31 at the moment when the stop switch 42 is operated. In the lottery of the combination by the combination lottery means 61, when no combination is won, the stop position of the reel 31 is determined so that the combination of symbols of any combination does not stop on the active line. Further, when any of the winning combinations is won, the stop position of the reel 31 is determined so that the combination of symbols of the winning combination can be stopped on the effective line.

  Here, in the game at the time of winning the special role, or in the game where the special role win is carried over and is not won for the small role or replay, the combination of the special role symbols will stop at the active line as much as possible. Within the range of the reel 31 stop control, the drawing-in control for the special combination is performed.

  In addition, when a small role or replay is won during a game in which a special role is overtaken, winning of the small role or replay is given priority. Therefore, at the time of winning the small role or replay, the stop position of the reel 31 is determined so that the combination of symbols of the special role does not stop on the active line even if the special role is carried over. ing.

  Furthermore, in the first embodiment, a plurality of types of reel stop control tables 65a are provided. The plurality of reel stop control tables 65a determines whether or not to stop the combination of symbols of the specific small role 1 on the effective line when the special small role 1 is won by the winning lottery means 61 (whether the specific small role 1 is won) No) is set differently depending on the operation order of the stop switch 42.

  That is, in a certain reel stop control table 65a, when the specific small combination 1 is won and the specific stop switch 42 is operated in the operation order (for example, right, middle, left), the specific small combination It is determined that the combination of symbols of 1 is stopped on the effective line, and it is determined that the combination of symbols of the specific small role 1 is not stopped on the effective line when operated in the other operation order.

  In the other reel stop control table 65a, when the specific small role 1 is won and the other specific stop switch 42 is operated in the operation order (for example, left, right, middle). It is determined that the combination of symbols of the specified small role 1 is stopped on the effective line, and it is determined not to stop the combination of the symbols of the specified small role 1 on the effective line when operated in the other operation order. ing.

Here, when the stop switches 42 respectively corresponding to the left, middle, and right reels 31 are represented by left, middle, and right, the operation order of the stop switches 42 is “left, middle, right”, “left, right, There are six types of “middle”, “middle, left, right”, “middle, right, left”, “right, left, middle”, and “right, middle, left”.
Each reel stop control table 65a is configured such that when the stop switch 42 is operated in any one of the operation orders, the specific small role 1 wins, and the stop switch 42 is operated in the other five operation orders. The stop position of the reel 31 is determined so that the specified small combination 1 does not win when the is operated.

FIG. 3 is a diagram showing a symbol arrangement of the reels 31 in the first embodiment. In FIG. 3, only the symbol arrangement of “Bell” is shown, and a predetermined symbol is also displayed in a blank part in the drawing, but the description is omitted here.
In FIG. 3, “bells” are arranged on each reel 31 at intervals of 4 symbols or 5 symbols, respectively. The symbol combination of “bell”-“bell”-“bell” is determined as the symbol combination of the specific small role 1.

  Here, as described above, the reel stop control means 65, when winning the winning combination, within the range of the stop control of the reel 31 so that the combination of symbols of the winning combination stops at the effective line as much as possible. The drawing-in control related to 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 winning combination, the reel 31 is controlled to move when stopped, so that By actively stopping such symbols, the winning rate of the winning combination is increased.

  The stop control of the reel 31 is normally set to 190 ms or less (within 5 symbols counting from the position where the stop switch 42 is detected). 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 positioned on the specific effective line, the symbol related to the winning combination is displayed on the specific effective line. Pull-in is controlled.

  Here, as shown in FIG. 3, in each reel 31, the symbols of “bell” are all arranged at intervals within 5 symbols. Therefore, when the specific small role 1 is won, the symbol of “bell” can be drawn into the effective line and controlled regardless of the position of the stop switch 42 that is turned on. Therefore, “bell”, which is the symbol of the specific small role 1, has a pull-in rate of 100%.

Further, the reel stop control means 65 includes reel stop control lottery means 65b.
The reel stop control lottery means 65b selects one reel stop control table 65a by lottery from among the plurality of reel stop control tables 65a when the winning combination lottery means 61 wins the specific small role 1. . Thereby, when the specific small combination 1 is won, the operation order of the stop switch 42 for winning the specific small combination 1 is determined by selecting any one reel stop control table 65a. As a selection method of the reel stop control table 65a, for example, a random number generation unit similar to that described in the role lottery unit 61 may be used.

(Winning determination means)
The winning determination means 66 determines whether or not the combination of symbols stopped on any one of the effective lines matches the predetermined combination of symbols for any combination when the reel 31 is stopped. The winning determination means 66 determines, for example, the symbol positioned on the effective line by detecting the angle at which the motor 32 is stopped, the number of steps, and the like, and based on this, determines the presence / absence of a winning combination.

  The winning determination means 66 does not determine the combination of symbols after the reel 31 actually stops, but from the position of the reel 31 at the moment when the stop switch 42 is operated, the reel 31 is controlled by the reel stop control table 65a. When the stop position is determined, it is also possible to determine the combination of symbols that stop at the active line.

(Payment means)
The payout means 67 determines a predetermined number of coins according to the winning combination when the winning determination means 66 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols of any combination. A medal is paid out to the player or credits are added.
When a replay is won, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

(Special game execution means)
The special game execution means 68 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 executing means 68 shifts from the normal game to the special game on condition that the combination of symbols stopped on the active line matches a predetermined combination of symbols of special roles.

  For example, when a BB winning is made, the normal game is shifted to the BB game, and when RB is winning, the normal game is shifted to the RB game. The special game execution means 68 is lit to turn on the lamp 33, output sound from the speaker 34, display an image on the image display device 35, etc. in order to notify the player that the game will be transferred to the special game when the game is transferred to the special game. Control to perform various effects.

  The special game execution means 68 controls the progress of the game during the BB game and the RB game. In the BB game, the special game execution means 68 first starts the first game. The first game is a game in which medals within a predetermined number (for example, three) are inserted as in the normal game. The combination drawn by the combination lottery means 61 in the first game is a small combination and a transition combination for shifting to the second game. In the first game, the upper limit of the number of games is predetermined as, for example, 30 times. The special game execution means 68 continues to count the number of games in the first game.

  Further, the special game executing means 68 is the first on the condition that the combination of symbols stopped on the active line matches the combination of symbols of the transition combination during the first game, that is, on the condition of winning the transition combination. Transition from the game to the second game.

  When the second game is entered, the special game executing means 68 counts the number of games in the second game and the number of winnings of the predetermined role. In the second game, for example, only one medal can be inserted, and only the effective line in the middle in the horizontal direction is activated, and the combination of symbols of a predetermined role is stopped on this effective line with a high probability of, for example, about 90% ( The game is controlled so that a predetermined combination wins. Then, the second game is continued until the number of winnings of the predetermined role reaches a specified number (for example, 8 times) or until the number of games reaches a specified number of times (for example, 12 times). In order to determine whether or not the second game end condition is satisfied, the special game executing means 68 counts the number of games and the number of winnings of a predetermined role.

  Then, the special game executing means 68 terminates the second game when the number of games of the second game or the number of winnings of the predetermined role reaches the specified number of times, and confirms that the condition for ending the BB game is not satisfied. As a condition, control is performed to return to the first game again.

  Here, in the BB game, the upper limit of the number of times of transition from the first game to the second game is set to a predetermined number (for example, three times). Therefore, at the end of the second game when the specified number of times is reached, the BB game is ended without moving to the first game again. For this reason, the special game executing means 68 counts the number of times of transition from the first game to the second game during the BB game. For example, 1 is added to the number of times of transition when the transition role wins during the first game during the BB game and the transition to the second game is made.

In the RB game, the second game in the BB game is performed as one set, that is, a game in which a predetermined role is won with a high probability until the specified winning number or the specified number of games is reached.
In the RB game, the special game executing means 68 continues to count the number of games or the number of winnings of a predetermined role.

  The special game execution means 68 continues to determine whether or not the special game end condition is satisfied during the special game, and ends the special game when it is determined that the special game end condition is satisfied.

  For example, when the special game is a BB game, the game in the second game when the number of games of the first game reaches the specified number of times or when the number of times of transition from the first game to the second game reaches the specified number of times. When any one of the number of times or the number of winnings of the predetermined role reaches the specified number of times, the special game executing means 68 determines that the BB game end condition is satisfied. Also, when the special game is, for example, an RB game, the special game execution means 68 determines whether or not the RB game end condition when either the number of games or the predetermined number of winnings reaches the specified number. It is determined that the condition is satisfied.

(Specific game execution means)
The specific game execution means 70 executes a specific game when a predetermined condition is satisfied, particularly in the present embodiment, on the condition that the specific game occurrence small role 4 is won in the lottery of the role by the role lottery means 61 It is. Here, if the specific game occurrence small combination 4 is won, the specific game is executed even if the specific game generation small combination 4 does not win. Further, when the specific game occurrence small role 4 is won again during execution of the specific game, the number of games of the specific game can be changed.

  The specific game is a specific game that is different from the special game (BB game or RB game) and has a larger medal earned number expectation value than the normal game. In the specific game of the first embodiment, when a specific small combination 1 is won, the operation order of the stop switch 42 for winning the specific small combination 1 is notified.

Further, in this embodiment, the specific game is played until the set number of games becomes 0 or until the combination of symbols of BB or RB stops on the active line (until BB or RB wins).
The specific game execution means 70 controls to end the specific game and shift to the normal game when the number of games set for the specific game becomes zero. Further, when the combination of symbols of the special combination (BB or RB) stops on the active line during the execution of the specific game, the specific game execution means 70 ends the specific game. Then, the special game execution means 68 controls to execute the special game.

Even during a specific game, the role lottery means 61 draws a role including a special role, and when the special role is won, the special role selection carryover means 63 carries over the special role.
Although not shown, the game control means 60 includes a specific game flag as a flag for determining whether or not to execute a specific game. When the execution condition for the specific game is satisfied, the specific game flag is turned on. On the other hand, when the execution condition of the specific game is not satisfied, the specific game flag is turned off.

In the present embodiment, the specific game execution means 70 includes the following means.
(Specific game execution discrimination means)
The specific game execution determination means 71 determines whether or not a specific game execution condition is satisfied. In the present embodiment, as described above, it is determined that the execution condition of the specific game is satisfied when the specific game occurrence small combination 4 is won in the lottery of the combination by the combination lottery means 61.

(Specific game count display means)
The specific game number display means displays the number of games during the specific game. The specific game number display means may be provided exclusively for the slot machine 10, but in this embodiment, the image display device 35 also serves as the specific game number display means. That is, during the specific game, the image display device 35 displays the number of games of the specific game.

(Specific game number initial value setting means)
The specific game number initial value setting means 72 sets an initial value of the number of games of a specific game when shifting to a specific game. The initial value is determined in advance, and is set to 10 games or 100 games in this embodiment.

FIG. 4 is a diagram for explaining a method of selecting an initial value of the number of games of a specific game by the specific game number initial value setting means 72.
In FIG. 4, in this embodiment, the player is stationed in either “angel mode” or “devil mode” during the game. Further, the angel mode is divided into “angel mode A” and “angel mode B”.

First, considering the BB game as a reference, after the end of the BB game, the mode shifts to the angel mode A with a probability of 1/1. That is, when the BB game is entered while residing in the angel mode A, the angel mode A is maintained after the end of the BB game. Further, when the BB game is entered while residing in the angel mode B or the devil mode, the angel mode A is entered after the end of the BB game.
After transitioning to Angel Mode A, he will stay in Angel Mode A for 100 games. After 100 games have elapsed, the player switches to the devil mode with a probability of 1/20 when winning the specific small role 1. The probability of 1/20 is determined by lottery using soft random numbers (the same applies to the transition based on the probability shown below).

  After shifting to the devil mode, the mode shifts to the angel mode B with a probability of 1/50 when winning the specific small role 1 in addition to the case of shifting to the angel mode A by the end of the BB game as described above. After transitioning to Angel Mode B, he will stay in Angel Mode B for 20 games. After 20 games have passed, the player switches to the devil mode with a probability of 1/7 when winning the specific small role 1.

When the slot machine 10 is initialized (when the RAM is initialized or the setting of the payout rate is changed), the following is performed.
When the initialization process is performed while the angel mode is in the angel mode A or B, the mode is shifted to the devil mode. On the other hand, when the initialization process is performed while residing in the devil mode, the mode shifts to the angel mode A.

  In the above angel mode A or B, or the devil mode, when the specific game occurrence small role 4 is won while residing in the angel mode A or B, the specific game number initial value setting means 72 The initial value of the number of games is set to 100 games. On the other hand, when the specific game occurrence small role 4 is won while residing in the devil mode, it is set to 10 games.

FIG. 5 is a diagram showing an example in which the initial value of the number of games set by the specific game number initial value setting unit 72 is displayed as an image by the specific game number display unit (image display device 35). In the figure, (a) shows an example of image display when the execution condition of the specific game is satisfied and the initial value of the number of games of the specific game is set to 100 games when residing in the angel mode. Also, (b) shows an example of image display when the specific game execution condition is satisfied when the user is stationed in the devil mode and the initial value of the number of games of the specific game is set to 10 games.
In FIG. 5, “AT” is an abbreviation for “Assist Time” and means a specific game of the present embodiment.

(Function selection means)
The function selection means 73 is a function for changing the number of games by causing the player to perform a predetermined operation so that the number of games set by the specific game number initial value setting means 72 can be changed. One of the functions is selected from a plurality of functions including a function that does not change the function.
That is, the number of games (10 games or 100 games) initially set by the specific game number initial value setting means 72 is not definitive, and the number of games is changed for the player before the specific game is executed. To give you the opportunity to do.

  FIG. 6 is a diagram showing the types of functions to be selected by the player and their winning probabilities. In the present embodiment, six functions are provided. In each function, P indicates the number of games, and the number indicates the rate. The higher the function, the lower the winning probability is set. For example, “P = 2P” means a function that doubles the number of games.

  In the function of FIG. 6, “P = 1P” is a function for maintaining the initial value of the number of games set by the specific game number initial value setting means 72 as it is. “P = 1.5P” is a function for maintaining half of the initial value of the number of games set by the specific game number initial value setting means 72 and doubling the remaining half. It is. Therefore, when “P = 1.5P” is won, the number of games is 1.5 times, and when not winning, the number of games is 0.5 times.

The function selection means 73 first displays an image of the contents corresponding to the above six functions on the specific game number display means. FIG. 7 is a diagram showing an example of image display at this time. In (a) to (f), the magnification of each function is displayed as “× N (N is a magnification)”. Then, (a) to (f) are repeated continuously, that is, (a) → (b) → (c) → (d) → (e) → (f) → (a) → .. To do. The images (a) to (f) are stopped and displayed for 1 to 2 seconds, respectively.
In (a), “AT” is to maintain the initial value of the number of games as it is, and corresponds to “P = 1P”.

  Then, the player selects one of the six functions by inserting a medal from the medal insertion slot 21 or operating the bet switch 23. When a medal is inserted from the medal slot 21, the medal is detected by the medal sensor 22.

  Here, when a medal is detected, the function corresponding to the content displayed on the image on the specific game number display means is selected. Similarly, when the bet switch 23 is operated, a signal generated by the operation is transmitted to the game control means 60. When the game control means 60 receives this signal, the function corresponding to the content displayed on the image on the specific game number display means is selected.

(Function validation decision means)
The function validation determination unit 74 determines whether or not to validate the function selected by the function selection unit 73. In this embodiment, it determines by lottery using a soft random number. As a lottery method, random number generating means similar to the above-described combination lottery means 61 can be used.

When one of the functions is selected, as shown in FIG. 6, it is determined whether or not to validate the function by lottery with a winning probability corresponding to the selected function.
Here, when the function of “P = 1P” is selected, the function validation determining unit 74 decides to validate the function unconditionally without performing a lottery.

(Determination result production control means)
When the decision result effect control means 75 decides whether or not the function selected by the function selection means 73 is to be validated by the function validation decision means 74, the decision result effect control means 75 displays the effect relating to the decision result as the specific game number display means. It controls to display by.
FIG. 8 is a diagram showing an example of the image display of the effect at this time. (A) to (e) respectively show image displays when “× 1.5”, “× 2”, “× 5”, “× 10”, and “× 30” are selected.

  For example, the example of FIG. 8A is when “× 1.5” is selected. In this case, if the function lottery is won, the number of games will be 1.5 times, and if it is not won, it will be 0.5 times, so that “× 1.5” and “× 0.5” respectively. An image is displayed. “× 1.5” is displayed with an angel image, and “× 0.5” is an example displayed with a devil image.

  In FIG. 8, both the magnification at the time of winning and the magnification at the time of non-winning are illustrated, but the image is displayed so as to scroll from top to bottom. For example, in the example of FIG. Images of “× 1.5” and “× 0.5” are alternately displayed.

  When the function validation determining means 74 determines whether or not to validate the function selected by the function selecting means 73, the decision result effect controlling means 75 is either an angel image part or a devil image. Control is performed so that either one of the portions is displayed as an image. FIG. 9 is a diagram showing an example at this time. FIG. 9 shows an example in which the function “× 5” is selected. FIG. 9A shows an example in which the function is determined to be valid and is stopped and displayed in the image “× 5”. Show. On the other hand, (b) shows an example in which the function is determined not to be validated and is stopped and displayed with an image of “× 0”.

(Game number calculation means)
When the function selection unit 73 selects a function for changing the number of games, the game number calculation unit 76 sets the specific game number initial value when the function activation determination unit 74 determines to enable the function. A new number of games is calculated by changing the number of games set by the setting means 72 in accordance with the function selected by the function selection means 73.

  In particular, in the present embodiment, when it is determined that the function is to be enabled by the function activation determining unit 74 (when a lottery is selected by the function activation determining unit 74), and it is determined that the function is not enabled. In both cases (when the lottery by the function validation determining means 74 is not won), a new number of games is calculated. When it is decided to activate the function by the function validation decision means 74, a new game in which the number of games set by the specific game count initial value setting means 72 is changed according to the function selected by the function selection means 73. Calculate the number of times.

  For example, when the number of games set by the specific game number initial value setting means 72 is 100 and the function selected by the function selection means 73 is “P = 2P”, the new number of games is calculated as 200. On the other hand, when the function validation determining means 74 decides not to validate the function, if the selected function is “P = 1.5P”, a new one is created according to “P = 0.5P”. Calculate the number of games. If the selected function is any other function, the new number of games is calculated as 0 according to “× 0”.

(Specific game number setting change means)
The specific game number setting changing unit 77 sets the new game number calculated by the game number calculation unit 76 as the game number of the specific game. The number of games of a specific game is stored in a storage unit of a specific game number update unit 78 described later, and a process of rewriting the value stored in the storage unit is performed.

  When the number of games of a specific game is set by the specific game number setting changing means 77, the specific game is started. When the number of games of a specific game is set to 0, the specific game is not executed and the normal game is executed.

(Specific game count update means)
The specific game number updating means 78 counts the number of games in the specific game, and sequentially updates the remaining number of games as the game is digested. The specific game number update means 78 includes a storage means such as a RAM for storing the number of games of a specific game. Then, during the specific game, the remaining number of games is subtracted by one for each game, and the remaining number of games stored in the storage means is sequentially updated.

  In addition, with the update of the number of games by the specific game number update unit 78, the display of the number of games by the specific game number display unit is also sequentially updated. FIG. 10 is a diagram showing an example of image display of the number of games by the specific game number display means. (A), (b) has shown the example when stationed in angel mode and devil mode, respectively. The player can determine whether he is currently in the angel mode or the devil mode by viewing the image display by the specific game number display means.

Also, as shown in FIG. 10, the number “0262” indicates the remaining number of games for a specific game. Each time a game is played, the display changes to “0261”, “0260”,..., And the display of the number of games is sequentially updated.
In addition to the number of games and modes, the number of medals acquired in a specific game (net increase) may be displayed together.

(Change condition discriminating means)
The change condition discriminating means 79 discriminates whether or not a condition for changing the number of remaining games of the specific game is satisfied during the specific game. In the present embodiment, the change condition discriminating means 79 is a condition for changing the remaining number of games of a specific game when the specific game occurrence small role 4 is won in the lottery of the role lottery means 61 during the specific game. It is determined that the condition is satisfied.

When it is determined by the change condition determining means 79 that the number of remaining games of the specific game is satisfied, that is, when the specific game occurrence small role 4 is won during the specific game, first, the specific game number initial value setting means 72 is used to play the game The initial value of the number of times is set. In addition, the function selection unit 73 causes the player to select one of a plurality of functions as described above.
The function validation determining unit 74 determines whether or not to validate the function selected by the function selecting unit 73.

  Then, when the function selection means 73 selects a function for changing the number of games, the game number calculation means 76 determines the number of specific games when the function validation determination means 74 decides to validate the function. A new number of games is calculated by changing the initial value of the number of games set by the initial value setting means 72 according to the function selected by the function selection means 73. Next, the specific game number setting change unit 77 adds the new game number calculated by the game number calculation unit 76 to the remaining game number so far, and sets a new remaining game number for the specific game.

  Further, the determination result effect control means 75 controls the effect related to the determination result of the function validation determination means 74 to be displayed by the specific game number display means, as described above.

As described above, when the remaining number of games for a specific game is changed during a specific game, the number of games is changed only for the newly acquired number of games.
For example, it is assumed that the specific game occurrence small role 4 is won when 50 games remain in the specific game. When the game at the time of winning is the angel mode, 100 games are awarded as the initial value of the number of games, and when the game is the devil mode, 10 games are awarded. When the function selected by the player is “P = 1P”, the newly assigned number of games is added to the current remaining number of games as it is. Therefore, the number of games after the addition is 150 games when winning the angel mode, and 60 games when winning the devil mode.

  In addition, when 50 games remain in the specific game and the specific game generation small role 4 is won in the angel mode, and 100 games are given as the initial value of the game number, the player is given “P = 2P ”Is selected. In this case, when the function is won, 200 games, which are double the number of newly granted 100 games, are added to make a total of 250 games. On the other hand, when the function is not won and the newly granted game count of 100 games becomes 0, the remaining game count of the specific game remains at the previous 50 games.

(Operation order notification control means)
The operation order notification control means 80 notifies the player of the operation order of the stop switch 42 for winning the specific small combination 1 when the specific small combination 1 is won during the specific game.
When any one reel stop control table 65a is selected by the reel stop control lottery means 65b, the operation order notification control means 80 stops for winning a specific small combination 1 corresponding to the reel stop control table 65a. The operation order of the switch 42 is determined, and control is performed so as to notify the player of the operation order.

As a 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.
FIG. 11 is a diagram illustrating an example in which the operation order of the stop switch 42 is displayed on the image display device 35. In the figure, the example of (a) shows that if the stop switch 42 is operated in the order of left, middle, and right, the selected special combination 1 can be won. Similarly, (b) in the figure is left, right, middle order, (c) is middle, left, right order, (d) is middle, right, left order, (e) is right, Left, middle order, (f) indicates right, middle, left order, respectively.

Here, when the specific small combination 1 is won during the specific game, the control is performed so as to notify immediately after the start switch 41 is turned on. The reason for this control is as follows.
When a specific small role 1 is won, the win is valid only in the game, and the win cannot be carried over to the next game. In other words, if the specific small role 1 is not won in the game won for the specific small role 1, the right to win is lost. For this reason, when the specific small combination 1 is won, in order to enable the reel 31 to be stopped so as to win the specific small combination 1, 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 win the specific small role 1.

  When the specific small combination 1 is won during the specific game, the operation order of the stop switch 42 is notified as described above, so that the player can know that the specific small combination 1 has been won by this notification. Furthermore, if the stop switch 42 is turned on according to the notified order (according to the order instructed by the slot machine 10), the specific small role 1 can be won reliably. That is, the pull-in rate of the “bell” symbol related to the specific small role 1 is set to 100%.

  On the other hand, during the normal game, even when the specific small combination 1 is won, the operation order of the stop switch 42 for winning the specific small combination 1 is not notified. Therefore, when a specific small role 1 is won during a normal game, if the operation order of the stop switch 42 for winning the specific small role 1 matches the order in which the player has operated in the game, the specific small role 1 The winning combination 1 wins, but the specified small winning combination 1 does not win in any other operation order. As described above, since there are six operation orders, the winning rate when the specific small combination 1 is won is 1/6 during a normal game.

Therefore, there is a 6-fold difference in the winning rate of the specific small role 1 between the specific game and the normal game. FIG. 12 is a diagram showing the number of games and the difference number (difference number = payout number−insertion number) between the specific game and the normal game in the first embodiment.
As shown in FIG. 12, when the number of games is taken on the horizontal axis and the difference between the payout and insertion of medals is taken on the vertical axis, in the normal game, the number of differences gradually decreases as the number of games increases. . The inclination value indicates the decrease rate of the difference number.

Here, for example, an expected value of the number of medals acquired during 50 games is considered. Assuming that a game is played with three medals inserted in each game, medals in 50 games based on specific small roles 1, small roles 2 and 3 and replays excluding BB, RB and specific game generating small roles 4 Expected number
In specific games, assuming that the winning rate when winning a specific small role 1 is 100%,
50 × (15 × 1/3 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 7.3) = about 280 sheets.
Therefore, between 50 games, 3 x 50 medals are inserted, so the increase / decrease number of medals is
280-3 × 50 = about +130 sheets.

On the other hand, in normal games, the winning rate at the time of winning the specified small role 1 is 1/6.
50 × (15 × 1/3 × 1/6 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 7.3) = about 71 sheets.
Therefore, the number of medals increased or decreased between 50 games is
71−3 × 50 = about −79 sheets.
Therefore, in specific games, medals increase with the number of games. On the other hand, in normal games, medals decrease with the number of games.

(Operation order detection means)
The operation order detection means 90 detects the operation order of the stop switch 42 when the specific small combination 1 is won. As described above, the stop switch 42 is provided for each of the reels 31, but the reel 31 that is turned on first (first) is the reel 31 among the left, middle, and right reels 31. It is detected whether the stop switch 42 corresponding to each of the reels 31 of the left, middle, and right reels 31 is the stop switch 42 that is turned on second. Each stop switch 42 is configured to transmit an identification signal to the operation order detecting means 90 when turned on.

Therefore, when the specific small combination 1 is won, one reel stop control table 65a is selected by lottery by the reel stop control lottery means 65b.
Further, the operation order of the stop switch 42 is detected by the operation order detection means 90.
Then, the reel stop control unit 65 refers to the selected reel stop control table 65a based on the detection result by the operation order detection unit 90, determines the stop position of the reel 31, and stops the reel 31 at that position. .

  Next, a game flow of the slot machine 10 will be described based on a flowchart. FIG. 13 to FIG. 16 are flowcharts for explaining the flow of games in the first embodiment. FIG. 14 is a flowchart following FIG. 13, and FIG. 15 is a flowchart following FIG. FIG. 16 is a flowchart subsequent to “4 (Yes in step S24)” in FIG.

  First, the player inserts a medal from the medal insertion slot 21 or operates the bet switch 23 to insert a medal into the slot machine 10, validates the effective line, and turns on the start switch 41. In step S1, the game control means 60 continues to detect whether or not the start switch 41 is turned on. When the turn-on is detected, the game control means 60 starts each reel 31 and proceeds to the next step S2. In step S2, the game control means 60 determines whether or not the specific game flag is on. When it is determined that the game is on (in the specific game), the process proceeds to step S3. When it is determined that the game is not on (in the specific game), the process proceeds to step S4.

  In step S3, the specific game number update means 78 performs a process for updating the number of games of the specific game. That is, since the game is started by turning on the start switch 41, a process of subtracting 1 from the number of games P of the specific game (P = P-1) is performed. Then, the process proceeds to step S4.

  In step S4, the part lottery means 61 performs a part lottery. Next, the process proceeds to step S5, where it is determined whether or not the special combination (BB or RB) has been won. If it is determined that the special combination (BB or RB) has not been won, the process proceeds to step S9. move on. In step S6, it is determined whether or not the winning special combination is BB. When it is determined that it is BB, the process proceeds to step S7, and when it is determined that it is not BB (which is RB), 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 winning number counter 64a (X = X + 1), and proceeds to step S9. In step S8, the special role winning carry-over means 63 adds 1 to the count value Y of the RB winning number counter 64b (Y = Y + 1), and proceeds to step S9.

In step S9, it is determined whether or not the specific small combination 1 has been won. When it is determined in step S9 that the specific small role 1 has been won, the process proceeds to step S10, and when it is determined that the specified small role 1 has not been won, the process proceeds to step S21.
In step S10, the reel stop control lottery means 65b performs lottery of the reel stop control table 65a, selects any one reel stop control table 65a, and proceeds to step S11.

In step S11, the game control means 60 determines whether or not the specific game flag is on. When it is determined that it is on, the process proceeds to step S12, and when it is determined that it is not on, the process proceeds to step S13.
In step S <b> 12, the operation order notification control unit 80 performs control so as to notify the operation order of the stop switch 42 for winning the selected small combination 1. As described above, the operation order notification control means 80 uses the image display device 35 to display an image of the operation order of the stop switch 42. Then, the process proceeds to step S13.

  In step S13, the game control means 60 continues to detect whether or not the first (first) stop switch 42 is turned on. When ON is detected, the process proceeds to step S14. In step S14, the operation order detection unit 90 detects which of the left, middle or right stop switch 42 is turned on, and proceeds to step S15.

  In step S15, the reel stop control means 65, based on the reel stop control table 65a selected in step S10 and the first stop switch 42 detected in step S14, the first reel corresponding to the first stop switch 42. 31 is controlled to stop.

Next, proceeding to step S16, 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 S17.
In step S17, the operation order detecting means 90 detects which of the left, middle or right stop switch 42 is turned on. Then, the process proceeds to step S18. In step S18, the reel stop control means 65 controls to stop the second reel 31 corresponding to the second stop switch 42 as in step S15.

Next, proceeding to step S19, the game control means 60 continues to detect whether the third (third) stop switch 42 has been turned on. When ON is detected, the process proceeds to step S20.
In step S20, the reel stop control means 65 controls to stop the third reel 31 corresponding to the third stop switch 42, as in step S15. Then, the process proceeds to step S24. Here, the reason why the third stop switch 42 is not detected after step S19 is that the first and second stop switches 42 have already been detected, so that the third stop switch 42 can be determined.

  On the other hand, when the process proceeds from step S9 to step S21, the game control means 60 continues to detect whether or not the stop switch 42 is turned on, and when it is detected, the process proceeds to step S22. In step S22, the reel stop control means 65 refers to the reel stop control table 65a based on the lottery result of the combination in step S4 and the timing when the stop switch 42 is operated. And the reel 31 is controlled to stop at the determined position.

  In the next step S23, the game control means 60 continues to determine whether or not all the reels 31 are stopped, and when it is determined that all the reels 31 are stopped, the process proceeds to step S24. On the other hand, when it is determined in step S23 that all the reels 31 are not stopped, the process returns to step S21.

In step S24, the winning determination means 66 determines whether or not the special combination has won, that is, whether or not the combination of the special combination symbols has stopped on the active line. When it is determined that the special combination is won, the process proceeds to “4” (step S41 in FIG. 16).
On the other hand, when it is determined that the special combination has not been won, the process proceeds to step S25, and the winning determination means 66 determines whether or not a small combination other than the special combination or replay has been won.

When it is determined in step S25 that a small combination or replay has been won, the process proceeds to step S26, and the payout means 67 performs processing such as paying out medals according to the winning combination. At the time of winning a small role, a payout process of the number of medals corresponding to the small role is performed and the process proceeds to step S27. Further, at the time of replay winning, a re-game process is performed while maintaining the number of medals inserted in the game, and the process proceeds to step S27.
On the other hand, when it is determined in step S25 that no winning combination has been won, that is, when no winning combination has been won, the process proceeds to step S27 without performing a payout process or the like.

In step S27, it is determined whether or not the specific game occurrence small combination 4 is won in the combination lottery in step S4. When it is determined that the player has won, the process proceeds to step S28. When it is determined that the player has not been won, the process proceeds to step S36.
In step S28, the fact that the specific game occurrence small role 4 has been won is notified. That is, depending on whether the game is the angel mode or the devil mode, the initial value of the number of games of the specific game (the number of games added when the game is already in the specific game) is 100 games or 10 games, respectively. Is displayed on the specific game number display means as shown in FIG.

In step S29, the function selection unit 73 causes the player to select one of the functions. As described above, the function is displayed as an image by the specific game number display means.
When a player inserts a medal from the medal insertion slot 21 or operates the bet switch 23, it is determined that a function has been selected, and the process proceeds to step S30.
In step S30, the function validation determining means 74 draws the selected function.

  Next, proceeding to step S31, the game number calculation means 76 determines the number of games of the specific game based on the lottery result. That is, when the selected function is “P = 1P”, the number of games initially set by the specific game number initialization value setting means 72 is determined as the number of games of the specific game or the number of games to be added. The Further, when the selected function is a function other than “P = 1P”, when winning, the number of games is calculated according to the magnification of the function, and a new number of games is determined. Further, when the winning is not made, the number of games of the specified game based on the winning of the specified game generation small role 4 is determined to be 0.

  In the next step S32, the specific game number setting changing means 77 performs a process for changing the number of games of the specific game. Next, proceeding to step S33, the specific game executing means 70 determines whether or not the number of games P for the specific game is zero. When it is determined that the number of games of the specific game is 0, the process proceeds to step S34, and the game control means 60 switches the specific game flag from on to off. That is, when the number of games of a specific game becomes 0, it is determined that the specific game end condition is satisfied, and control is performed so as to end the specific game. And the process by this flowchart is complete | finished.

  On the other hand, when it is determined in step S33 that the number of games is not 0, the process proceeds to step S35, and the game control means 60 turns on the specific game flag or if it is already on, the state is displayed. maintain. And the process by this flowchart is complete | finished.

  On the other hand, when the process proceeds from step S27 to step S36, the game control means 60 determines whether or not the specific game flag is on. When it is determined that the specific game flag is not on, the process according to this flowchart is terminated. On the other hand, if it is determined to be on, the process proceeds to step S37. In step S37, the specific game executing means 70 determines whether or not the number of games P for the specific game is zero. When it is determined that it is not 0, the processing according to this flowchart is terminated.

  On the other hand, when it is determined that the value is 0, the process proceeds to step S38. In step S38, the game control means 60 switches the specific game flag from on to off. That is, when the number of games reaches 0, it is determined that the specific game end condition is satisfied, and control is performed to end the specific game. And the process by this flowchart is complete | finished.

  On the other hand, when the process proceeds from step S24 to step S41 in FIG. 16, the winning determination means 66 determines whether or not the BB has won, that is, whether or not the combination of symbols of the BB has stopped on the active line. When it is determined that BB has won, the process proceeds to step S42, and when it is determined that BB has not won (RB has won), the process proceeds to step S45.

  In step S42, the special role winning carry-over means 63 subtracts 1 from the count X of the BB winning number counter 64a (X = X-1), and proceeds to step S43, where the special game executing means 68 starts the BB game. To do. On the other hand, in step S45, the special role winning carry-over means 63 subtracts 1 from the count value of the RB winning count counter 64b (Y = Y-1), and proceeds to step S46, where the special game executing means 68 Start an RB game. That is, in step S42 and step S45, the count value for the special combination won is subtracted by 1.

  When the BB game is started in step S43, the process proceeds to step S44, and the special game executing means 68 advances the BB game and continues to determine whether or not the BB game end condition is satisfied. If it is determined that the BB game end condition is satisfied, the process proceeds to step S48.

  Similarly, when the RB game is started in step S46, the process proceeds to step S47, and the special game executing means 68 proceeds with the RB game and continues to determine whether or not the RB game end condition is satisfied. If it is determined that the RB game end condition is satisfied, the process proceeds to step S48.

  In step S48, the game control means 60 determines whether or not the specific game flag is on. When it is determined that the game is on, the process proceeds to step S49 to turn off the specific game flag. That is, when a transition is made to a BB game or an RB game during a specific game, the specific game flag is turned off in order to end the specific game even if the number of games of the specific game remains. And the process by this flowchart is complete | finished. On the other hand, when it is determined in step S48 that the specific game flag is not on, the processing according to this flowchart is terminated.

(Second Embodiment)
Subsequently, a second embodiment of the present invention will be described. FIG. 17 is a block diagram showing an outline of the slot machine 10A in the second embodiment. In the second embodiment, parts different from the first embodiment are denoted by “A”. Moreover, what attached | subjected the code | symbol same as 1st Embodiment has a function similar to 1st Embodiment.

  In the second embodiment, the special combination winning counter 64 shown in the first embodiment is not provided. The special role winning carry-over means 63 carries over only the winning of one special role. Therefore, in the game from winning a special role in the role lottery means 61 and winning until the special role is won, the random number extracted by the random number extraction means of the role lottery means 61 is in the winning area of the special role. Even if it belongs, it is not determined that the special role is won, but is determined not to be won.

  Further, in the game before winning a prize after winning the special combination, when the specific game occurrence small combination 4 is won, the specific game execution determining means 71 determines that the execution condition of the specific game is not satisfied. Furthermore, after winning the special role during the specific game, and in the game before winning a prize, when the specific game occurrence small role 4 is won, the change condition determining means 79 is a condition for changing the number of remaining games of the specific game. Is determined not to be satisfied.

Similarly to the specific game number update unit 78 of the first embodiment, the specific game number update unit 78A counts the number of games in the specific game, and sequentially updates the remaining number of games as the game is digested. It is. However, after the special game number update unit 78A wins the special role (BB or RB) during the specific game, the specific game number update unit 78A stops updating the game number of the specific game and interrupts the specific game.
Then, when the special game is executed by the special game execution means 68 and the special game is finished, the specific game execution means 70A controls to restart the specific game.

  18 and 19 are flowcharts showing the flow of processing in the second embodiment. 18 and 19 show only the parts different from the first embodiment. Other processes are the same as those in the first embodiment.

  In the second embodiment, when the lottery of the combination is performed in step S4 in FIG. 13, the process proceeds to step S51 in FIG. In step S51, it is determined whether or not the special role (BB or RB) has been won. If it is determined that the special combination (BB or RB) has not been won, the process proceeds to step S9 in FIG. move on. In step S52, it is determined whether or not the specific game flag is on. If it is determined that the specific game flag is on, the process proceeds to step S53. In step S53, the specific game number updating means 78A stops updating the number of games in the specific game. Further, the specific game number updating unit 78A stores the number of games of the specific game at the time when the update is stopped in a predetermined storage unit. In the next step S54, the game control means 60A turns off the specific game flag. Then, the process proceeds to step S9 in FIG. On the other hand, when it is determined in step S52 that the specific game flag is not on, the process proceeds to step S9 in FIG.

  In the second embodiment, when it is determined in step S24 in FIG. 14 that the special combination has won, the process proceeds to step S61 in FIG. In step S61, the winning determination means 66 determines whether or not BB has won, that is, whether or not the combination of symbols of BB has stopped on the active line. When it is determined that BB has won, the process proceeds to step S62, and when it is determined that BB has not won (RB has won), the process proceeds to step S64.

  In step S62, the special game executing means 68 starts a BB game. In step S63, the special game executing means 68 advances the BB game and continues to determine whether or not the BB game end condition is satisfied. If it is determined that the BB game end condition is satisfied, the process proceeds to step S66.

  On the other hand, in step S64, the special game executing means 68 starts an RB game. In step S65, the special game executing means 68 proceeds with the RB game and continues to determine whether or not the RB game end condition is satisfied. If it is determined that the RB game end condition is satisfied, the process proceeds to step S66.

  In step S66, it is determined whether or not the update of the number of games during the specific game is stopped by the specific game number update means 78A. This determination is made based on whether or not the number of games of the specific game at the time when the specific game number updating unit 78A stops updating in step S53 is stored in a predetermined storage unit. When it is determined that the update of the number of games during the specific game is stopped, the process proceeds to step S67.

In step S67, the game control means 60A turns on the specific game flag, and proceeds to step S68. In step S68, the number of games of the specific game immediately before winning the special combination, that is, the number of games stored in the predetermined storage means described above is set. Further, the specific game number updating means 78A restarts the update of the number of games in the specific game after the next game. Then, the process ends.
On the other hand, when it is determined in step S66 that the update of the number of games has not been stopped, the process is terminated.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
FIG. 20 is a block diagram showing an outline of the slot machine 10B in the third embodiment. In the third embodiment, “B” is attached to the reference numerals for parts different from the first embodiment. Moreover, what attached | subjected the code | symbol same as 1st Embodiment has a function similar to 1st Embodiment.

In 3rd Embodiment, the symbol arrangement | sequence of the reel 31 differs from 1st Embodiment. FIG. 21 is a plan view showing an arrangement of 21 symbols on the outer peripheral surface of each reel 31 in the third embodiment. In FIG. 21, unlike the actual symbols, the symbols are represented by characters. For example, “red 7” means a design of “7” colored red.
The symbols displayed on the reel 31 are composed of seven types of “red 7”, “blue 7”, “BAR”, “bell”, “cherry”, “watermelon”, and “plum”. Various combinations corresponding to the combination of symbols on the reel 31 are determined in advance.

  The probability table 62B of the third embodiment is different from the probability table 62 of the first embodiment. FIG. 22 is a diagram showing each combination in the third embodiment, a winning probability in the probability table 62B, a payout number of each combination, and a combination of symbols of the reel 31 corresponding to each combination.

  The probability table 62B is different from the probability table 62 of the first embodiment in the configuration of the combination. In the third embodiment, three types of specific small roles 1A to 1C are provided. Each of the specific small roles 1A to 1C has a winning probability set to 1/15. Further, the symbol combination of the specific small role 1A is “red 7”-“bell”-“bell”, and the symbol combination of the specific small role 1B is “blue 7”-“bell”-“bell”. Yes, the combination of symbols of the specific small role 1C is defined as "BAR"-"Bell"-"Bell".

  In the third embodiment, the contents of the specific game are different from those in the first embodiment. In the third embodiment, during a specific game, when any one of the specific small roles 1A to 1C is won, the game notifies the player of the winning of the specific small role.

  Here, as shown in FIG. 21, “Red 7”, “Blue 7” and “BAR” which are symbols constituting the specific small role of the left reel 31 are arranged in No. 2, No. 9 and No. 16, respectively. Has been. That is, each of these symbols is arranged at seven symbol intervals. In this way, if it is informed which specific small role is won, the stop switch 42 can be operated so that the specific small role wins, and which specific small role is won. If you do not know whether you are doing, it is to ensure that the selected small role does not necessarily win. Details thereof will be described below.

  In the slot machine 10B, the same stop control of the reel 31 as in the first embodiment is performed. In other words, 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 positioned on the specific effective line, the symbol related to the winning combination is displayed on the specific effective line. Pull-in is controlled.

  For example, when the specific small role 1A, which is a combination of symbols “red 7”-“bell”-“bell”, is won, the second reel “red 7” to the sixth “plum” on the left reel 31 If the stop switch 42 is turned on at the moment when is positioned on the specific effective line, the second “red 7” stops on the specific effective line. On the other hand, when the stop switch 42 is turned on at any other position, no prize is won even if the specific small role 1A is won.

  In this embodiment, during the specific game, the player is notified of the winning of the specific small role, so that the player can operate so that the symbol related to the selected small role is stopped on the active line. it can.

  However, in a normal game, since the winning of the specific small role is not notified, the player can win the specific small role only in 1/3 of the specific game. For example, the player predicts that the specific small role 1B related to “Blue 7” is elected, and sets the stop switch 42 of the left reel 31 so that the symbol “Blue 7” stops on the specific effective line. In the case of the stop operation, if the specific small role 1B is actually elected, the symbol “blue 7” related to the specific small role 1B stops on the specific active line. At this time, the condition is that the stop switch 42 is turned on at the moment when the symbols from the 9th to the 13th of the left reel 31 are located on the specific effective line.

  However, when the player's prediction is wrong and the specific small role 1A or 1C whose symbol of the left reel 31 is “red 7” or “BAR” is elected, the position where the player turns on the stop switch 42 From the second, “red 7” of No. 2 on the left reel 31 and “BAR” of No. 16 cannot be drawn on the specific effective line. In other words, in order for the second “red 7” to stop on the specific effective line, as described above, the stop switch 42 must be turned on at the moment when the symbols 2 to 6 are positioned on the specific effective line. Because it must. Similarly, in order for No. 16 “BAR” to stop on the specific effective line, the stop switch 42 must be turned on at the moment when the symbols from No. 16 to No. 20 are located on the specific effective line. is there.

  As shown in FIG. 21, in the middle reel 31 and the right reel 31, all the symbols of “bell” are arranged at intervals within 5 symbols. Therefore, when one of the specific small roles is elected, for the middle reel 31 and the right reel 31, the “bell” symbol can be drawn onto the active line and controlled regardless of the position at which the stop switch 42 is turned on. it can. Therefore, the “bell” that is the symbol of the middle reel 31 and the right reel 31 of the specific small role has a pull-in rate of 100%.

Furthermore, in the third embodiment, the reel stop control means 65B includes a reel stop control table 65c, and unlike the first embodiment, the reel stop control lottery means 65b is not provided.
The reel stop control means 65B is the same as the reel stop control means 65 of the first embodiment. Further, unlike the first embodiment, the reel stop control table 65c is not provided with a plurality of different types depending on the operation order of the stop switch 42.

The specific game execution means 70B of the third embodiment includes a winning specific small combination notification control means 81.
(Winning specified small role notification control means)
The winning specific small role notification control means 81 tells the player which of the three types of specific small roles 1A to 1C has been won when winning the specific small role during the specific game. It controls to notify. For example, the winning specific small combination notification control unit 81 controls the lamp 33 to blink in a specific pattern and output a specific sound from the speaker 34, and the image display device 35 displays the selected specific small role. Control is performed so as to display an image of one of the specific small roles 1A to 1C.

Here, the winning specific small combination notification control means 81 controls to notify immediately after the start switch 41 is turned on when the specific small combination is won. This is due to the following reason.
When a specific small role 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 specified small role is not won in a game won by the specified small role, the right to win will be lost. For this reason, when a specific small role is won, control is performed so as to notify immediately after the start switch 41 is turned on so that the reel 31 can be stopped so as to win the specific small role.

  In addition, when a specific small combination is won, the player is notified of the design of the left reel 31. The combinations of the symbols of the three types of specific small roles 1A to 1C are combinations of “red 7”, “blue 7” or “BAR”-“bell”-“bell”, respectively, and only the symbol of the left reel 31 However, the symbols of the middle reel 31 and the right reel 31 are “bells” in any of the specific small roles 1A to 1C. Therefore, if only the symbol of the left reel 31 is notified to the player, the player can know which specific small role has been won.

  For this reason, for example, when the specific small combination 1A consisting of the combination of “red 7”-“bell”-“bell” is won, the winning specific small combination notification control means 81 displays “red” on the image display device 35. 7 ”is displayed. Similarly, when a specific small combination 1B composed of a combination of “blue 7”-“bell”-“bell” is won, control is performed to display an image of “blue 7” and the like. Further, similarly, when a specific small role 1C having a combination of symbols “BAR”-“bell”-“bell” is won, control is performed so as to display an image of “BAR” or the like.

  As described above, when a specific small combination is won during a specific game, the winning of the specific small combination is notified, so that the player can win the specific small combination. Since the winning probability of each specific small combination is 1/15, the probability of winning any specific small combination is 3/15. As a result, during the specific game, the specific small combination can be won with a probability of 3/15.

  On the other hand, in a normal game in which the winning of a specific small role is not notified, the player knows that any specific small role will be won with a probability of 3/15, but whether or not it is won in that game. And which specific small role is elected. As described above, in a normal game, the player can win a specific small combination only by 1/3 of the specific game.

Therefore, there is a three-fold difference in the winning rate of the specific small role between the specific game and the normal game.
Here, for example, an expected value of the number of medals acquired during 50 games is considered. Assuming that a game is played with three medals inserted in each game, the specific small roles 1A to 1C, the small roles 2 and 3, excluding BB, RB and the specific game generating small role 4, and 50 games based on replay The expected number of medals won is
In a specific game, assuming that the winning rate at the time of winning the specific small roles 1A-1C is 100%,
50 × (15 × 3/15 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 7.3) = about 180 sheets.
Therefore, between 50 games, 3 x 50 medals are inserted, so the increase / decrease number of medals is
180-3 × 50 = about +30 sheets.

On the other hand, in the normal game, when the winning rate at the time of winning the specific small roles 1A to 1C is assumed to be 1/3,
50 × (15 × 1/15 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 7.3) = about 80 sheets.
Therefore, the number of medals increased or decreased between 50 games is
80-3 × 50 = about −70 sheets.
Therefore, in specific games, medals gradually increase with the number of games. On the other hand, in normal games, medals decrease with the number of games.

  In the third embodiment, unlike the first embodiment, since the operation order of the stop switch 42 is not notified, the operation order notification control means 80 and the operation order detection means 90 in the first embodiment are the same. Not provided.

FIG. 23 is a flowchart showing the flow of processing in the third embodiment. FIG. 23 shows only the parts different from the first embodiment.
In the third embodiment, the processes from step S9 in FIG. 13 to step S24 in FIG. 14 are different from those in the first embodiment. Other processes are the same as those in the first embodiment.
In step S9 of FIG. 13, the game control means 60B determines whether or not the specific small combination is won in the combination lottery. When it is determined that any of the specific small roles 1A to 1C has been won, the process proceeds to step S71, and when any specific small role has not been won, the process proceeds to step S73.

In step S71, the game control means 60B determines whether or not the specific game flag is on, that is, whether or not the game is a specific game. When it is determined that it is on, the process proceeds to step S72, and when it is determined that it is not on, the process proceeds to step S73.
In step S72, the winning specific small combination notification control means 81 performs control so as to notify the selected specific small combination. As described above, the winning specific small combination notification control unit 81 uses the lamp 33, the speaker 34, and the image display device 35 to notify which one of the selected specific small combinations is 1A to 1C. To control. Then, the process proceeds to step S73.

  In step S73, the game control means 60B continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S74. In step S74, the reel stop control means 65B determines the stop position of the reel 31 with reference to the reel stop control table 65c based on the lottery result of the combination and the timing when the stop switch 42 is operated. Then, the reel 31 is controlled to stop at the determined position.

  In the next step S75, the game control means 60B continues to determine whether or not all the reels 31 are stopped, and when it is determined that all the reels 31 are stopped, the process proceeds to step S24 in FIG. On the other hand, when it is determined in step S75 that all the reels 31 are not stopped, the process returns to step S73. Since the process after step S24 is the same as that of the first embodiment, the description thereof is omitted.

(Fourth embodiment)
Subsequently, a fourth embodiment of the present invention will be described. In the fourth embodiment, the contents of the specific game are different from those in the first to third embodiments. In the specific game of the third embodiment, the winning probability of replay is significantly higher than that in the normal game, and the replay is frequently won.

  FIG. 24 is a block diagram showing an outline of a slot machine 10C in the fourth embodiment. In the fourth embodiment, “C” is attached to the reference numerals of the parts different from the first embodiment. Moreover, what attached | subjected the same code | symbol as 1st Embodiment is the same as that of 1st Embodiment.

  The fourth embodiment includes reel stop control means 65C and reel stop control table 65d corresponding to the reel stop control means 65B and reel stop control table 65c of the third embodiment, and unlike the first embodiment, reel stop control lottery. Nothing corresponding to 65b is provided. Different from the first embodiment, the reel stop control table 65d is not provided with a plurality of different types depending on the operation order of the stop switch 42.

Furthermore, in the fourth embodiment, since the notification of the winning of the specific small role is not performed, unlike the third embodiment, the component corresponding to the winning specific small role notification control means 81 is not provided.
Furthermore, in the fourth embodiment, unlike the first embodiment, since the operation order of the stop switch 42 is not notified, what corresponds to the operation order notification control means 80 and the operation order detection means 90 in the first embodiment is as follows. Not provided.

(First probability table, second probability table)
The probability table 62C of the fourth embodiment includes two types, a first probability table 62a and a second probability table 62b. The first probability table 62a is used during normal games, and the second probability table 62b is used during specific games.

FIG. 25 is a diagram illustrating winning probabilities and the like of each combination in the first probability table 62a and the second probability table 62b according to the fourth embodiment.
As shown in FIG. 25, in the fourth embodiment, unlike the first embodiment or the like, no specific small combination is provided. Like the small roles 2 and 3, the small role 1 is a normal small role.

  In the first probability table 62a and the second probability table 62b, the winning probabilities other than replay are set to be the same for both. The winning probability of the replay is 1 / 7.3 in the first probability table 62a as in the first embodiment, but is 1 / 1.6 in the second probability table 62b, and the replay probability of the first probability table 62a. It is set significantly higher than the winning probability.

Here, the probability obtained by subtracting the sum of the winning probabilities of all of these combinations from the probability 1/1 (100%) is the non-winning probability of not winning any combination. The non-winning probability in the first probability table 62a is about 1 / 1.3 (about 77%).
On the other hand, the non-winning probability in the second probability table 62b is about 1 / 3.6 (about 28%). That is, the winning probability of replay in the second probability table 62b is set higher than the non-winning probability.

Subsequently, the slope values of the first probability table 62a and the second probability table 62b will be described.
FIG. 26 is a diagram for explaining slope values of the first probability table 62a and the second probability table 62b, and corresponds to FIG. The slope value in FIG. 26 is a value including the winning probability of replay.

  As shown in FIG. 26, in the normal game in which the first probability table 62a is used, the difference number gradually decreases as the number of games increases. On the other hand, at the time of a specific game in which the second probability table 62b is used, the difference number hardly decreases as the number of games increases.

Here, for example, the increase / decrease rate of medals between 50 games is considered. It is assumed that the winning rate of the winning small role or replay is 100%. Assuming that 3 medals are inserted in each game and the game is played, the expected number of medals obtained in 50 games based on small roles 1 to 3 and replay excluding BB and RB is:
In the first probability table 62a,
50 × (15 × 1 / 19.5 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 7.3) = about 68 sheets.
Therefore, between 50 games, 3 × 50 medals are inserted, so the rate of increase / decrease (inclination value) of medals is
68 / (3 × 50) = about 0.45
It becomes.

On the other hand, the expected number of medals acquired in the second probability table 62b is
50 × (15 × 1 / 19.5 + 8 × 1/85 + 4 × 1/45 + 3 × 1 / 1.6) = about 141 sheets.
Therefore, the medal increase / decrease rate (slope value) between 50 games is
1411 / (3 × 50) = about 0.94
It becomes.

As described above, the slope value of the second probability table 62b is set higher than the slope value of the first probability table 62a.
That is, the first probability table 62a has a general inclination value at the time of a normal game, while the second probability table 62b has an inclination value close to 1 (100%). When using the second probability table 62b, as well as the first probability table 62a, as well as winning a small role, replays are frequently won (with a probability of 1 / 1.6), and almost due to the continuation of the game. A state in which the number of owned medals does not decrease, in other words, a gaming state in which the number of medals owned by the player is almost maintained.

  The specific game according to the fourth embodiment is a game in which a lottery for a role is performed using the second probability table 62b. Thereby, during a specific game, a game state in which replays are frequently won is established. When the replay is won, the reel stop control means 65C performs drawing pull-in control so that the combination of the replay symbols stops on the active line. Thereby, during the specific game, the replay winning probability is increased.

  In addition, in the case where the winning of the special role is carried over during the specific game, in order to win the special role, it is a condition that the small role or the replay is not won. Because, when winning a small role or replay, priority is given to the winning small role or replay winning, and the stop control is performed to draw the selected small role or replay symbol into the active line, and the special role symbol is activated. This is because stop control is not performed.

  Therefore, since the winning probability of replay is high during the specific game, the chances of stopping the combination of symbols of special roles for which the winning has been carried over are reduced. Therefore, it is difficult for a special role to win a prize during a specific game, despite the fact that the special role has been won. However, during the specific game, the game can be performed with almost no reduction in the number of medals, and there is a possibility that the special combination will be won again during the specific game. Since the selected special combination is carried over, it is advantageous for the player to move to the specific game.

FIG. 27 is a flowchart showing the flow of processing in the fourth embodiment. In FIG. 27, only the parts different from the first embodiment are shown.
The fourth embodiment differs from the first embodiment in the processing up to step S24 in FIG. The processes after step S24 are the same as in the first embodiment.

First, in step S81, the game control means 60C continues to detect whether or not the start switch 41 is turned on. When the turn-on is detected, each reel 31 is started and the process proceeds to the next step S82.
In step S82, the game control means 60C determines whether or not the specific game flag is on. When it is determined that the game is on (in the specific game), the process proceeds to step S83. When it is determined that the game is not on (in the specific game), the process proceeds to step S84.

  In step S83, the game control means 60C sets the second probability table 62b as the probability table 62C used for the winning lottery of the winning lottery means 61. Then, the process proceeds to step S85. In step S85, the specific game number update means 78 performs a process for updating the number of games of the specific game. That is, since the game is started by turning on the start switch 41, a process of subtracting 1 from the number of games P of the specific game (P = P-1) is performed. Then, the process proceeds to step S86.

  On the other hand, in step S84, the game control means 60C sets the first probability table 62a as the probability table 62C used for the winning lottery of the winning lottery means 61. Then, the process proceeds to step S86.

  In step S86, the part lottery means 61 performs a part lottery. Next, the process proceeds to step S87, where it is determined whether or not the special combination (BB or RB) has been won. If it is determined that the special combination (BB or RB) has not been won, the process proceeds to step S91. move on. In step S88, it is determined whether or not the winning special combination is BB. When it is determined that it is BB, the process proceeds to step S89, and when it is determined that it is not BB (which is RB), the process proceeds to step S90.

  In step S89, the special role winning carry-over means 63 adds 1 to the count value X of the BB winning number counter 64a (X = X + 1), and proceeds to step S91. In step S90, the special role winning carry-over means 63 adds 1 to the count value Y of the RB winning number counter 64b (Y = Y + 1), and proceeds to step S91.

  In step S91, the game control means 60C continues to detect whether or not the stop switch 42 is turned on, and when on is detected, the process proceeds to step S92. In step S92, the reel stop control means 65C refers to the reel stop control table 65d on the basis of the lottery result of the winning combination in step S86 and the timing when the stop switch 42 is operated. And the reel 31 is controlled to stop at the determined position.

  In the next step S93, the game control means 60C continues to determine whether or not all the reels 31 are stopped. When it is determined that all the reels 31 are stopped, the process proceeds to step S24 in FIG. On the other hand, when it is determined in step S93 that all the reels 31 are not stopped, the process returns to step S91. Since the process after step S24 is the same as that of the first embodiment, the description thereof is omitted.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications as described below are possible.
(1) In the present embodiment, examples of three types of specific games have been given. However, the specific games are not limited to these, and are different from special games, and the expected number of medals won from the normal game. It ’s fine if it ’s a big game.

  Furthermore, in the specific game, a game with a higher winning rate for replay as in the fourth embodiment is combined with a game with a higher winning rate for the specific small role as in the first, second or third embodiment. It may be a thing. In this case, by setting the winning probability of the specific small combination and the number of payouts to appropriate values, it is possible to obtain a game state in which the number of medals is hardly reduced even when the game is continued, that is, the number of medals is almost maintained. . Alternatively, a gaming state in which medals increase with the number of games can be achieved.

(2) The conditions for executing the specific game and the conditions for changing the number of games of the specific game during the specific game are the cases where the specific game occurrence small role 4 is won. However, in addition to this, various conditions are defined, for example, when a predetermined combination wins, a specific symbol combination appears in the display window frame, a predetermined combination wins or the number of winnings reaches a specified number, etc. be able to.
Further, for example, when the game is shifted to a special game (both or one of the BB game and the RB game), it may be determined that the condition for uniformly executing the specific game is satisfied after the special game ends. Then, when the function selection means 73 causes the player to select a function and the function validation determination means 74 decides to validate the function, the specific game may be executed.

  Further, for example, when a game that does not win a special role and does not shift to a specific game lasts for a long time (over 1000 games), it may be determined that the execution condition of the specific game is compulsory. .

  (3) In the present embodiment, five functions of “P = 1.5P” to “P = 30P” are given as examples as a function for changing the number of games of a specific game as shown in FIG. It is not limited to these functions. For example, one that adds a predetermined number of times such as “P = P + 30”, “P = P + 100”, one that subtracts a predetermined number of times from the current number of games such as “P = P−10”, or these May be combined. Here, when the predetermined number of times is subtracted from the current number of games, if the number of games after the subtraction becomes a negative value, the specific game should be ended in the same manner as when the number of games is zero. It ’s fine. That is, the game number calculation means 76 calculates a new game number obtained by changing the previous game number according to the function, and when the new game number becomes negative as a result of the calculation, the new game number is calculated. Set to 0.

  Furthermore, a function for adding a predetermined number of times and a function for changing to a predetermined number, such as “P = P + 10” and “P = 2P”, may be provided and selected by lottery or the like. Further, the number of functions set in advance may be any number (may be one).

  (4) In the first embodiment and the like, when winning a special role during a specific game and shifting to a special game, the specific game flag is turned off at the end of the special game. However, the present invention is not limited thereto, and the specific game flag may be kept on, and the specific game may be resumed after the special game ends. Alternatively, when the game shifts to the BB game during the specific game, the specific game flag is turned off after the end of the BB game, and when the game shifts to the RB game during the specific game, the specific game flag is kept on. good.

  In addition, when transitioning to a special game during a specific game, when a specific condition is satisfied during the special game (when the number of medals earned in a special game exceeds a predetermined number, or a combination of specific symbols appears In this case, the specific game flag may be kept on, and when the specific condition is not satisfied, the specific game flag may be turned off at the end of the special game.

  (5) In this embodiment, the initial value of the number of games of a specific game is set to 10 games or 100 games, but this is not limiting, and any number of games may be used. For example, a special initial value of the number of games may be set only when a specific condition is satisfied. For example, when the specific game occurrence small role 4 is won in the first game after the end of the BB game, or when the specific game occurrence small role 4 is won in the first game after the initialization process of the slot machine, etc. Alternatively, the initial value of the number of games for a specific game may be set to 500 games or the like.

  (6) In the present embodiment, when the function validation determining means 74 decides not to validate the function, when a function other than the function of “P = 1P” is selected, the game of the specific game The number of times was set to zero. However, the present invention is not limited to this, and when it is decided not to validate the function, the number of games set by the specific game number initial value setting means 72 is maintained and the game of the specific game by the specific game number setting changing means 77 is maintained. The setting of the number of times may not be changed.

  (7) In the present embodiment, the number of games of a specific game up to that time is determined even when it is determined to be “× 0” as a result of selecting a function and selecting a function during a specific game. Was to be maintained. That is, the number of games can be changed only for the number of games newly acquired during a specific game. However, the number of games may be changed with respect to the number of games obtained by adding up the number of games of a specific game so far and the number of newly acquired games.

  (8) In the first embodiment or the like, when a specific small role is won, if the stop switch 42 is turned on in a predetermined operation order, the specific small role always wins. However, even when the stop switch 42 is turned on in a predetermined operation order, the specific small combination may not be awarded unless the stop switch 42 is turned on at an appropriate position. That is, the symbols may be arranged so that the drawing rate of the symbols constituting the specific small role does not become 100%.

  (9) In the first embodiment or the like, in the case of a small role in a specific game that has won the BB winning or a game that has not won the replay, the combination of symbols of the BB that has won the winning will stop on the active line There is. If the combination of symbols of the BB carrying over winning is stopped on the active line, the game shifts to the BB game, but the specific game is ended.

Therefore, in such a case, it is possible to control so that the specific game does not end, that is, the combination of symbols of BB does not stop on the active line.
For example, during a specific game that carries over winning of BB, a combination of BB symbols does not stop on the active line, or a reel stop control table that is difficult to stop is used.

  In the first embodiment, the reel stop control table 65a is defined such that when the stop switch 42 is operated in a specific operation order, the combination of symbols of the BB carrying the winning is not stopped on the effective line. It is also good. In this case, if a specific game that has been won by BB is not won for a small role or replay, and if a specific operation order is notified to the player, the player can use the combination of symbols of BB as an effective line. You will be able to avoid stopping.

  (10) In the third embodiment, three types of specific small roles are provided, but two types or four or more types may be provided. And when providing two types of specific small roles, what is necessary is just to provide the symbol which comprises both the specific small roles on the reel 31 in the position separated by 5 symbols or more.

  In addition, when a plurality of types of specific small roles are provided, two symbols constituting different specific small roles may be arranged at intervals of 5 symbols or less. In this case, when the stop switch 42 is turned on with the symbol of the specific small role that the player has guessed during the normal game, the specific small role is not won but the specific small role related to the winning is within five symbols ahead. When there is a symbol, the selected small combination may be accidentally won by the stop control of the reel 31. For example, when 5 to 7 types of specific small roles are provided, depending on the arrangement of symbols constituting the specific small roles, it may be possible to draw in any of the symbols constituting 2 to 3 specific small roles. .

  However, at the time of a specific game, it is possible to win without losing the selected specific small role, but at the time of a normal game, the winning rate at the time of winning the specific small role is lower than at the time of the specific game. Therefore, there is no particular problem because a difference in the number of acquired medals can be provided between the specific game and the normal game.

  In the present invention, when at least one reel 31 wins a specific small role, the symbol that forms the selected specific small role cannot be pulled in by the stop control of the reel 31 and the symbol that forms another specific small role. As long as at least one of the symbols is arranged, the symbols constituting a plurality of types of specific small roles may be arranged.

  (11) In the third embodiment, the number of payouts at the time of winning for each specific small role is set to 15 in all cases, but the number of payouts may be less than that or may be different for each specific small role. good.

  (12) In the third embodiment, among the symbols constituting the specific small combination, the pull-in rate of the middle reel 31 and the right reel 31 is 100%, but is not limited to this. The design of the left reel 31 may be arranged on any reel 31. Furthermore, the symbols may be arranged so that the drawing rate of the symbols constituting the specific small role is not 100% for all the reels 31.

  (13) In the first to third embodiments, only when a specific small combination is won, the operation order of the stop switch 42 or the selected specific small combination is notified. However, although the winning probability of the specific small role is not 100%, it may be notified when there is a possibility of winning the specific small role. For example, during a specific game, notification is given only when a specific small role is elected (the reliability of notification is 100%), and during normal games, the above notification is given even during non-winning (the reliability of notification is changed). (Less than 100%).

  (14) In the fourth embodiment, only the replay winning probability is different between the first probability table 62a and the second probability table 62b. However, the present invention is not limited to this, and the winning probabilities of special roles and small roles may be different. Furthermore, although the slope value of the second probability table 62b is about 0.94, it is not limited to this. For example, the replay winning probability may be set higher, the winning probabilities of the small roles 1 to 3 may be set higher, or the number of payouts may be set to be larger than 1.

(15) Furthermore, in the fourth embodiment, the winning probability of replay in the second probability table 62b is 1 / 1.6 in this embodiment. However, it is not limited to this value. If the winning probability of replay is more than the probability of not winning any role, and if the game can proceed without reducing the number of medals as usual, how to set the winning probability Also good.
