  Recently, a slot machine provided with a probability variation game is actually being proposed to the market. In this case, it becomes a problem how to incorporate a part unique to the slot machine and how to differentiate from the probability variation game of the ball ball game machine that has been widely known conventionally.

  Therefore, the problem to be solved by the present invention is to provide a probability variation game in the slot machine by making use of the game characteristic peculiar to the slot machine.

The present invention solves the above-described problems by the following means.
According to the first aspect of the present invention, the winning probability of the first special role for causing the player to play the first special game that is advantageous to the player is set to X1, and the winning probability of the replay for causing the player to replay is set. The first special lottery table having the winning area of the second special role for shifting to the second special game which is set to X2 and advantageous to the player, and the winning area of the specific small role, and the first special role And a second role lottery table in which the winning probability is set to Y1 (Y1> X1) and the winning probability of the replay is set to Y2 (Y2> X2). A normal game that draws a role using a table, and a probability variable game that draws a role using the second role lottery table, and the first special role during the normal game or the probability variable game Won the first special When the combination of symbols corresponding to is stopped on the active line, the process proceeds to the first special game, and when the number of game media to be paid out during the first special game becomes equal to or greater than a prescribed value Z1, 1 special game is controlled to end, and when winning the second special role, no matter what timing the player operates the stop switch, the combination of symbols corresponding to the selected second special role is always The symbols corresponding to the second special combination are arranged so as to stop at the active line, the reel stop control is performed, and the second special combination is won during the normal game, and the second special combination is selected. When the combination of symbols corresponding to the combination stops on the active line, the game shifts from the normal game to the second special game, and in the second special game, the combination including the specific small combination is performed, Specific small At the time of winning, control is performed so that the combination of symbols corresponding to the specific small role is stopped on the effective line, and if the combination of symbols corresponding to the specific small role cannot be stopped on the effective line, It controls to display a unique outcome at the time of winning the small role, the second special role has a second special role A and a second special role B, and the symbol corresponding to the second special role A when combination is shifted to the second special game stops enable line, symbol after its second special game ended, the control is shifted to the probability change game, corresponding to the second special won B combination is stopped on the activated line when the shift to the second special game, after the end of the second special game is controlled so as to shift to the normal game, the second special won a and the second In the special role B winning game, it will be played in the non-winning game of the role Outputting an effect similar effect to be force, the second when a combination of symbols corresponding to the special role A is shifted to the second special game stops enable lines, corresponding to the second special won B than when a combination of symbols is shifted to the second special game stops enable lines, by increasing the probability that the payout speed is more game media of the second in special game, the second special game by increasing the degree of expectation that the more payout number of game media in it shifts to the probability change game after the end of the second special game, the second special by payout number of game media of the second in special game It is suggested that the game after the end of the game is the probability variation game or the normal game .

  According to a second aspect of the present invention, in the slot machine according to the first aspect, during the normal game, a lottery including a small role is drawn, and a combination of symbols corresponding to the small role is "A"- A ”-“ A ”is set, and the combination of symbols corresponding to the replay is set to“ B ”-“ B ”-“ B ”. The symbols“ A ”and“ B ”are The symbol “A” and the symbol can be always stopped at a desired effective line regardless of the timing at which the player operates the stop switch. "B" is arranged and stop control of the reel is performed, and the symbol combination corresponding to the second special combination is composed of the symbol "A" and the symbol "B". Features.

  According to a third aspect of the present invention, in the slot machine according to the first or second aspect, the second special game is a game in which stop control of the reel is different from the normal game.

According to a fourth aspect of the present invention, in the slot machine according to any one of the first to third aspects, a lottery of a combination including the replay is performed during the second special game. .
According to a fifth aspect of the present invention, in the slot machine according to any one of the first to fourth aspects, after the first special game is over, the game is shifted to the probability variation game.

(Function)
In the above invention, when the second special combination is won, the selected second special combination always wins. When the second special combination wins during the normal game, the second special game is executed. In the second special game, when a specific small combination is won, the selected specific small combination wins or a unique outcome is displayed. Then, after the end of the second special game, the probability variation game is executed.

Therefore, for example, if the combination of symbols relating to the second special combination is difficult to understand, it is possible to make it difficult for the player to notice that the second special combination has won.
Furthermore, it is possible to suggest the degree of expectation for transition to the probability-changing game according to the number of payouts of game media in the second special game.

(Relationship between solving means and first embodiment)
In the first embodiment, the first special role (first special game) is 1BB (1BB game), the second special role A is 2BB-A, 2BB-C, or 2BB-E, and the second special role The role B is 2BB-B, 2BB-D, or 2BB-F.
The winning probability of 1BB in the first combination lottery table 62A is set to 1/300 (total value) and the winning probability of replay is set to 1 / 7.3, whereas in the second combination lottery table 62B The winning probability of 1BB is set to 1/75 (total value), and the winning probability of replay is set to 1/2. The specific small combination is a small combination 1.
Furthermore, a payout number of specified value Z1 of game media in the first in special game is set to 345 sheets or 120 sheets, payout number of game media in the second in special game is 45 sheets or 30 sheets Is set.
Then, in the second special game (2BB game) to which the second special role A (2BB-A, 2BB-C, or 2BB-E) has won and transferred, the payout number of game media is 45 with a probability of 2/3. In the second special game (2BB game) in which the second special role B (2BB-B, 2BB-D, or 2BB-F) wins and moves, the number of game media payouts is 2/3 probability. 30 sheets.

  Furthermore, in claim 2, the symbol combination “A”-“A”-“A” corresponding to the small role is the symbol combination “bell”-“bell”-“bell” corresponding to the small role 1. The symbol combinations “B”-“B”-“B” corresponding to the replay are “R”-“R”-“R”. 2BB-A and 2BB-B are composed of symbols “Bell” and “R”.

  According to the present invention, the second special game with a short number of games is used, and after the end of the second special game, the game is shifted to the probability variation game. This makes it difficult for the player to notice and gives the player an impression as if the probability variation game has suddenly started. In addition, it is possible to make it easier for a specific game to appear during the second special game, and to give the player an expectation that if a specific game appears, the game may shift to a probability-changing game.

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 control of the slot machine 10 in the first embodiment.
The game control means 60 of the slot machine 10 is means for comprehensively controlling the entire slot machine 10 including the progress and effects of the game of the slot machine 10, and includes lottery of the role, drive control of the reel 31, and payout at the time of winning. It controls the progress of the game and the output of the production. The game control means 60 is provided on the control board, and is a CPU that performs calculations, a ROM that stores programs necessary for the progress of the game, data for production, and the like, and when the CPU performs various controls. RAM etc. which memorize | store the data etc. which were taken in are temporarily stored.

As shown in FIG. 1, a bet switch 40, a start switch 41, and a stop switch 42 are electrically connected to the input side (left side in FIG. 1) of the game control means 60.
The bet switch 40 is a switch that is operated when a player inserts a stored medal, and is a switch in which an effective line is set by the operation. Although the medal insertion slot is not shown in FIG. 1, the medal insertion slot is a part for inserting an actual medal for setting an effective line, like the bet switch 40. The insertion of medals is included in the operation of the bet switch 40.

The start switch 41 is a switch operated by the player when starting the reel 31.
Furthermore, three stop switches 42 are provided corresponding to the three reels 31 and are operated by the player when stopping the corresponding reels 31.

Peripheral devices such as the motor 32 described below are 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 combination of symbols corresponding to a combination) is attached is attached to an outer peripheral surface thereof.

  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.

  Here, in the present embodiment, the reel 31 is provided with left, middle, and right three, and the stop switch 42 is provided with left, middle, and right three correspondingly. That is, the reel 31 corresponding to the left stop switch 42 is the left reel 31, the reel 31 corresponding to the middle stop switch 42 is the middle reel 31, and the reel 31 corresponding to the right stop switch 42 is the right reel 31.

  Furthermore, the output side of the game control means 60 is electrically connected to effect output devices such as the lamp 21, the speaker 22, and the image display device 23.

  The lamps 21 are effects lamps for the slot machine 10 and are turned on in a predetermined pattern when predetermined conditions are satisfied. The lamp 21 includes a back lamp (not shown) arranged on the inner peripheral side of each reel 31, an upper lamp and a side lamp which are arranged on the front surface of the casing of the slot machine 10 and blink when a winning combination is made. A lamp (not shown) and the like are included.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
Furthermore, the image display device 23 includes a liquid crystal image display device, a dot display, and the like, and displays various effect images, predetermined information, and the like during the game.

Although not shown, a symbol combination line (effective line) is provided in a portion including the display window of the slot machine 10.
Here, the “symbol combination line” is a line of symbols when the reel 31 is stopped, and is a line that forms a combination of symbols. In the present embodiment, it is composed of a total of five lines: lines provided respectively in the middle, upper, and lower stages in the horizontal direction, and diagonal lines in the downward and leftward diagonal directions. The three symbols that are continuous above and below each reel 31 are positioned on one or more symbol combination lines.

Further, among the five symbol combination lines, an effective line and an invalid line are set from the symbol combination lines according to the number of medals inserted or set by the player.
Here, in the present embodiment, the “effective line” is a line for winning a combination when a combination of symbols corresponding to any combination stops on the line.

  On the other hand, the “invalid line” is generated when the number of inserted medals is one or two, and is a line that is not set as an effective line among the symbol combination lines, and a combination of symbols corresponding to any of the combinations. Even if the line is stopped, a profit according to the combination (medal payout etc.) is not performed. In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

  The number of medals inserted in one game can be selected by the player from one to three. When the number of medals inserted is 1, the horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbol combination lines are set as invalid lines. When the number of inserted medals is 2, the horizontal, middle, upper and lower symbol combination lines (total of three) are set as valid lines, and the other two symbol combination lines are set as invalid lines. The Furthermore, when the number of inserted medals is 3, all the symbol combination lines (a total of 5) are set as valid lines and there are no invalid lines.

  FIG. 2 is a diagram illustrating the types of winning combinations (the winning combinations selected by the winning lottery means 61, which will be described later), the number of payouts or the end conditions, the combination of symbols, and the winning probability in the first embodiment. As shown in FIG. 2, special combinations, small combinations, replays, and predetermined combinations are provided as combinations.

The special role is a role that shifts from a normal game to a special game (a game in which a medal can be expected more than a normal game). In this embodiment, as shown in FIG. 2, 1BB (first type big bonus) and 2BB (second type big bonus) are provided as special combinations. 1BB is a role to shift to 1BB game which is one of special games, and 2BB is a role to shift to 2BB game which is another one of special games.
Other special combinations include RB (regular bonus) and SB (single bonus), which are not provided in the present embodiment.

  Furthermore, a small combination is a combination in which a predetermined number of medals are paid out. In this embodiment, three types of small combination 1, small combination 2, and small combination 3 are provided. The combination of symbols and the number of payouts at the time of winning are set differently for each small role.

Furthermore, the replay is a replaying role that enables a replaying game in which the number of medals inserted in the game is maintained.
In addition, the predetermined combination is a combination that is drawn by lottery during 1BB game (in RB game).

Each of the above combinations includes a plurality of types provided for one combination. The first is 1BB, and three types of 1BB-A to 1BB-C are provided. The second is 2BB, and six types of 2BB-A to 2BB-F are provided.
The above-mentioned multiple types of roles are independent from each other. For example, when 1BB-A is won, only 1BB-A is won and 1BB-B or 1BB-C is won. Must not. Furthermore, when 1BB-A is won, only 1BB-A can win, and 1BB-B and 1BB-C do not win.
The same applies to 2BB.

Further, as shown in FIG. 2, combinations of symbols of the reel 31 corresponding to the various kinds of roles described above are determined in advance. Further, the symbol combination of 2BB is composed of a combination of symbols of “bell” relating to the small role 1, “watermelon” relating to the small role 2, and “R” relating to the replay. In particular, in the present embodiment, the reel 31 is provided with a lot of “bell” and “R” symbols. This makes it difficult to notice that 2BB has won the prize.
Note that “any” in the small role 3 means that any symbol may be used.
When all the reels 31 are stopped, the combination of symbols corresponding to any of the combinations stops on the active line, and when the winning combination of the combination is won, the number of medals corresponding to the combination is paid out.

In each of the above-mentioned combinations, if the combination of symbols corresponding to the combination does not stop on the active line in the game selected for the combination, a combination that is carried over after the next game and a combination that is not carried over are determined. .
Special roles (1BB and 2BB) can be cited as carry-overs. When the special combination is won, in the game until the combination of symbols corresponding to the special combination stops on the active line when the reel 31 is stopped, the special combination is controlled to be carried over from the next game onward.

  In this way, the winning of special roles is carried over, while roles other than special roles are not carried over. When a role other than the special role is won in the lottery of the role, the winning role is valid only in the game, and the winning is not carried over after the next game. In other words, in the game where these winning combinations are won, the reel 31 is controlled to stop so that the combination of symbols corresponding to the winning combination can be stopped (winning) on the active line. Regardless, at the end of the game, the right to the winning role will cease.

A game in which a special role is not won (a game in which a special role is not carried over) is referred to as “non-internal”. In addition, the combination of symbols corresponding to the selected special combination is not stopped on the active line (not winning) in the game (the special combination is selected) The game that is carried over) is called “inside”.
Although details will be described later, when 2BB is won, 2BB always wins in the game, so the winning of 2BB is not carried over after the next game.

  At the start of the game, the player operates the bet switch 40 to insert a previously stored medal, or inserts a medal from the medal insertion slot, and turns on the start switch 41. When the start switch 41 is operated, a valid line is determined and a signal generated at that time is input to the game control means 60. When the game control means 60 (specifically, the reel control means 64 described later) receives this signal, it controls to drive all the motors 32 and rotate all the reels 31. As the reel 31 is rotated by the motor 32 in this way, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window at a predetermined speed.

  Then, the player presses each stop switch 42 to stop the rotation of each reel 31. When the stop switch 42 is operated, a signal generated at that time is input to the game control means 60. When the game control means 60 (specifically, the reel control means 64 described later) receives this signal, it controls the drive of the motor 32 corresponding to the stop switch 42 and controls the stop of the reel 31 related to the motor 32. I do. When all the reels 31 are stopped, when the combination of symbols on the reels 31 stopped on the effective line matches a predetermined combination of symbols of the winning combination, The medals are paid out according to the winning combination.

The game control means 60 includes the following part lottery means 61 and the like. 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.
The role lottery means 61 performs lottery of a role (special role, small role, replay, and predetermined role described above). The role lottery means 61 is based on, for example, a random number generation means (hardware random number, etc.) for a role lottery, a random number extraction means for extracting a random number generated by the random number generation means, and a random value extracted by the random number extraction means. And determining means for determining the presence / absence of a winning combination and the winning combination.

  The random number generation means generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number is, for example, a random number for which the counter that performs 1 count at 200 n (nano) sec continues to count as a cycle in the range of 0 to 65535, and continues to count the random number while the slot machine 10 is powered on. .

  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 combination lottery table 62 described later. For example, if the extracted random number value belongs to the small role 1 winning area, it is determined that the small role 1 is selected, and if it belongs to the non-winning area, it is determined to be non-winning.

The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. The combination lottery table 62 includes a specific combination lottery table 62 for each gaming state. Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination. The predetermined ratio is set so as to be the winning probability (winning probability shown in FIG. 2).
Here, as the gaming state of the present embodiment, a normal game (non-inside), a probability variation game, a normal game (inside), a 1BB game (in RB game), and a 2BB game are provided. .

  As the role lottery table 62, a role lottery table 62A used during a normal game (non-inside), a role lottery table 62B used during a probability variation game, a role lottery table 62C used inside a normal game, A role lottery table 62D used during the 1BB game (in RB game) and a role lottery table 62E used during the 2BB game are provided.

FIG. 3 is a diagram showing the role lottery tables 62A and 62B. Illustration of the role lottery tables 62C to 62E is omitted.
The winning lottery table 62A is provided with 1BB (1BB-A to 1BB-C), 2BB (2BB-A to 2BB-F), small portion 1, small portion 2, small portion 3, and replay winning areas. Yes. Each of these combinations is set to have a winning probability indicated by “normal time” during the winning probability in FIG.
Further, the winning lottery table 62B is provided with 1BB (1BB-A to 1BB-C), 2BB (2BB-A to 2BB-F), small winning combination 1, small winning combination 2, small winning combination 3, and replay winning areas. It has been. Each of these combinations is set to have a winning probability indicated by “when probability changes” during the winning probability in FIG. In other words, the winning lottery table 62B is set to have a higher probability of winning 1BB and replay than the winning lottery table 62A.

  Furthermore, the winning lottery table 62C has no winning areas of 1BB (1BB-A to 1BB-C) and 2BB (2BB-A to 2BB-F) as compared to the winning lottery table 62A (the winning areas are Set in the non-winning area).

Further, the combination lottery table 62D is provided with a small combination 1, a small combination 2, a small combination 3, and a winning area for a predetermined combination. Note that the winning probabilities of the small combination 1, the small combination 2, and the small combination 3 are the winning probabilities indicated by “normal” among the winning probabilities in FIG.
Further, the winning combination lottery table 62E has winning areas for a small combination 1, a small combination 2 and a small combination 3. The winning probabilities of the small combination 1, small combination 2, and small combination 3 are the same as those in the combination lottery table 62D.

When the special combination winning means 63 wins the special combination, the winning combination of the special combination is continued in the game until the combination of symbols corresponding to the special combination stops on the active line (until the special combination wins). It controls to carry over after a game.
Although not shown, a special combination flag is provided for each combination of symbols and is turned on when winning (for example, the special combination flag relating to 1BB-A is turned on when winning 1BB-A), and the special combination is awarded. When turned off.

  The reel control means 64 starts rotation of all the reels when the start switch 41 is operated, and controls the drive of the motor 32 when the stop switch 42 is operated, so that the reel stop control range is reached. The reel 31 corresponding to the stop switch 42 is controlled to stop.

  Here, “within the range of the stop control of the reel 31” means the amount of movement (rotation amount) of the reel 31 from the moment when the stop switch 42 is operated until the reel 31 actually stops. In the embodiment, in principle, (1) the movement control amount of the reel 31 from when the stop switch 42 is operated (momentary) until the reel 31 is stopped is within 5 symbols including the symbol, or (2) the stop switch The stop control time from when the 42 is operated (instant) until the reel 31 is stopped is within 190 ms (hereinafter referred to as “first stop control”).

In the 2BB game, “within the range of stop control of the reel 31” means that the left reel 31 is (1) a symbol that is controlled to move by one symbol from the symbol when the stop switch 42 is operated (instant). Or (2) The stop control time from when the stop switch 42 is operated (instant) until the reel 31 is stopped is within 75 ms (hereinafter referred to as “second stop control”).
Note that the middle reel 31 and the right reel 31 in the 2BB game are the first stop control.

The stop position determination table 65 defines the stop position (stop symbol) 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.
The stop position determination table 65 is provided for each combination, and is used for 1BB table (3 types) used for winning 1BB-A to 1BB-C, and for winning 2BB-A to 2BB-F, respectively. 2BB tables (6 types), a small role 1 table to a small role 3 table used when winning a small role 1 to a small role 3, respectively, a replay table used when winning a replay, a 2BB game table used during a 2BB game, A non-winning table that is used in non-winning state when not winning.

The 1BB-A table is used on condition that 1BB-A is won in the game, or 1BB-A is won in the game before the game and is not won in the game, and the reel 31 is stopped. Within the control range (within the range of the first stop control), the symbol combination corresponding to 1BB-A is stopped on the effective line, and the symbol combination corresponding to a role other than 1BB-A is not stopped on the effective line. In addition, the combination of symbols when the reel 31 is stopped is determined.
The same applies to 1BB-B and 1BB-C, and “1BB-A” in the 1BB-A table is replaced with “1BB-B” and “1BB-C”, respectively.

Furthermore, the 2BB-A table is used on the condition that 2BB-A is won in the game, and within the range of the stop control of the reel 31, the combination of symbols corresponding to the selected 2BB-A is made an effective line. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to a combination other than the winning 2BB-A is not stopped on the effective line.
Also, 2BB-B, 2BB-C, 2BB-D, 2BB-E, 2BB-F, small role 1, small role 2, small role 3, and replay are the same as above, and the above 2BB-A table “2BB-A” is changed to “2BB-B”, “2BB-C”, “2BB-D”, “2BB-E”, “2BB-F”, “small role 1”, “small role 2”, respectively. It will be read as “small role 3” and “replay”.

  Furthermore, the 2BB game table is used during the 2BB game regardless of winning / non-winning of the small combination 1 to small combination 3, and is used at the time of stop control of the middle reel 31 and the right reel 31. In the 2BB game table, the stop position of the reel 31 is determined so that the combination of symbols corresponding to the small combination 1 or the small combination 3 is preferentially stopped on the active line. Before the middle reel 31 and the right reel 31 are stopped, the left reel 31 is controlled to stop. As a result, when the symbol “cherry” relating to the small part 3 stops on the active line, The stop position of the reel 31 is determined so that the combination of symbols corresponding to any of the combinations does not stop on the effective line.

  Furthermore, for the left reel 31 during the BB game, stop control (second stop control) by software of the reel 31 is performed without using the stop position determination table 65. As will be described later, when the left reel 31 is subjected to the second stop control, the “cherry” or “bell” is stopped at any effective line regardless of the position of the left stop switch 42 operated at any position. Can be made. Therefore, when the left stop switch 42 is operated during the 2BB game, the stop position (“Cherry” or “Bell”) is stopped at one of the effective lines based on the position of the left reel 31 at that moment. The position of the reel 31 is searched, and the reel 31 is controlled to stop at the searched position by the second stop control. Note that the stop position in the second stop control is either a position at the moment when the stop switch 42 is operated or a position in which movement is controlled by one symbol.

  Furthermore, the non-winning table is used in a non-winning game that does not carry over the winning of the special role, and the symbol when the reel 31 is stopped so that the combination of symbols corresponding to any of the combinations does not stop on the active line. Are defined.

Next, the relationship between the symbol arrangement on the reel 31 and the stop control of the reel 31 in this embodiment will be described.
FIG. 4 is a plan view showing a symbol arrangement on the outer peripheral surface of each reel 31 in the first embodiment. In FIG. 4, only the symbols “Bell” and “Cherry” are shown, but a predetermined symbol is also displayed in a blank part in the drawing, and the illustration is omitted in FIG. 4. Yes.

As shown in FIG. 4, on each reel 31, 21 symbols are arranged at equal intervals.
In all the reels 31, the symbols “Bell” are all arranged at intervals within 5 symbols. Therefore, symbols of “bell” are arranged on the reel 31 at intervals within the range of the first stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated).

Therefore, the “bell” symbol can be controlled to always stop the “bell” symbol at a desired effective line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated. Yes (in the case of the first stop control).
Thereby, in the present embodiment, in the game where the winning combination 1 is won, the winning combination 1 always wins.

Further, although not shown, all the reels 31 are arranged with an interval of “R” or less within 5 symbols. Accordingly, symbols “R” are arranged on the reel 31 at intervals within the range of the first stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated).
Therefore, the “R” symbol can be controlled to always stop the “R” symbol at a desired effective line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated. Yes (in the case of the first stop control).

Further, although not shown, in the middle reel 31 and the right reel 31, all the “watermelon” symbols are arranged at intervals of 5 symbols or less. Accordingly, symbols of “watermelon” are arranged on the reel 31 at intervals within the range of the first stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated).
Therefore, the middle reel 31 and the right reel 31 are controlled so that the “watermelon” symbol is always stopped at a desired effective line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated. (In the case of the first stop control).

As described above, in this embodiment, the control of the “bell” and “R”, the middle reel 31 and the right reel 31 “watermelon” on all the reels 31 is always stopped at a desired effective line. it can.
As a result, 2BB-A composed of a combination of symbols “R”-“Bell”-“R”, 2BB-B composed of a combination of symbols “R”-“R”-“Bell”, “R”-“ 2BB-C consisting of a combination of symbols R "-" Watermelon ", 2BB-D consisting of a combination of symbols" R "-" Bell "-" Watermelon ", Symbols" R "-" Watermelon "-" Bell " 2BB-E consisting of a combination of "R"-"Watermelon"-2BB-F consisting of a combination of symbols "R", Replay consisting of a combination of symbols "R"-"R"-"R", "Bell A predetermined combination consisting of a symbol combination of “-R”-“R” is always won in a winning game.

  In particular, for 2BB, all 6 types will win in the winning game. For this reason, since 2BB is a special combination, the winning combination is carried over after the next game. In this embodiment, the winning game is always set to win.

  Also, during the 2BB game, the left reel 31 is stopped by the second stop control. However, regardless of the position (left) stop switch 42 is operated, either “Cherry” or “Bell” is used. Can be stopped on any active line. For example, in the left reel 31 of FIG. 4, when the left stop switch 42 is operated at the moment when the symbols of No. 14, No. 15, and No. 16 are located in the display window, The “bell” symbol can be stopped at the active line. In addition, when the left stop switch 42 is operated at the moment when the symbols No. 15, No. 16, No. 17 are located in the display window, the movement control is performed by one symbol, and the No. 16, No. 17, No. 18 symbols are displayed. By stopping within the display window, the 18th “bell” symbol can be stopped at the active line.

  The stop symbol discriminating means 66 discriminates whether or not the symbol combination of the reel 31 stopped on the effective line matches the symbol combination corresponding to any combination when the reel 31 is stopped. The stop symbol discriminating means 66 discriminates the symbol on the effective line by detecting, for example, the angle or the number of steps when the motor 32 is stopped.

  The stop symbol discriminating means 66 does not discriminate the symbol combination after the reel 31 is actually stopped, but the stop position of the reel 31 is determined from the position of the reel 31 at the moment when the stop switch 42 is operated. It is possible to determine a combination of symbols on the active line at a predetermined time.

  The payout unit 67 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols corresponding to any of the combinations by the stop symbol determining unit 66 and the winning combination is won. In addition, a predetermined number of medals corresponding to the winning combination is paid out to the player, or processing such as credit addition is performed. Further, at the time of replay winning, control is performed so that medals are automatically inserted without paying out medals.

The special game control means 68 controls the transition to the special game, the progress of the game during the special game, the end of the special game, and the like.
First, the special game control means 67 controls to shift to the special game on the condition that the combination of symbols corresponding to the special combination is stopped on the active line, that is, the special combination is won. For example, when 1BB wins, the game shifts to 1BB game, and when 2BB wins, the game shifts to 2BB game.
In addition, when the game shifts to the 1BB game or the 2BB game, the role lottery table 62 is changed to the specific role lottery table 62 (in the 1BB game, the role lottery table 62D in the 2BB game, the role lottery table 62E in the 2BB game). Can be switched.

First, when 1BB wins, the special game control means 68 controls to start the 1BB game from the next game. When the 1BB game is started, the special game control means 68 performs control so that the game state is set to RB game immediately before the start of the game. In the RB game, the combinations drawn by the combination lottery means 61 are the small combination 1, the small combination 2, the small combination 3, and the predetermined combination as described above. However, in the RB game, the predetermined combination is determined by the combination lottery table 62D so that the predetermined combination is won with a high probability of 1 / 1.2.
.

  Then, the special game control means 68 pays out medals corresponding to the combination when the combination of symbols corresponding to any combination stops on the active line during the RB game. In addition, the RB game of this embodiment continues until the number of winning a winning combination reaches a specified number (8 times in this embodiment) or until the number of games reaches a specified number (12 times in this embodiment). Is done.

  The special game control means 68 controls to end the RB game when the number of winning prizes or the number of games in the RB game reaches a specified number. However, immediately before the start of the next game, the special game control means 68 performs control so that the game state is set to the RB game again.

The end condition for the 1BB game is determined until the number of medals paid out during the 1BB game reaches a specified value.
Here, as shown in FIG. 2, when 1BB-A or 1BB-B wins / wins and shifts to 1BB game, the prescribed value of 1BB game is set to 345 cards.
On the other hand, when 1BB-C wins / wins and shifts to 1BB game, the prescribed value of 1BB game is set to 120.

  Therefore, the special game control means 68 counts the number of medals paid out during the 1BB game, and controls to end the 1BB game when the specified value is reached. That is, during the RB game, even if the number of winning combinations and the number of games have not reached the prescribed number, when the number of medals paid out reaches the prescribed value, the control is performed so that the 1BB game is terminated at that point. To do.

  When 2BB wins, the special game control means 68 controls to execute the 2BB game after the next game. In 2BB games, a small combination 1 to a small combination 3 is drawn. Regardless of the lottery result, as described above, the small combination 1 or the small combination 3 is preferentially controlled, and either one is always controlled. It is controlled to win (receive 15 payouts).

Furthermore, the 2BB game end condition is determined until the number of medals to be paid out during the 2BB game reaches a specified value.
Here, as shown in FIG. 2, when 2BB-A to 2BB-C are elected and won and transferred to 2BB game, the prescribed value of 2BB game is set to 45 (that is, 3 games). ing.

On the other hand, when 2BB-D to 2BB-F wins and wins and shifts to 2BB game, the prescribed value of 2BB game is set to 30 (that is, 2 games).
Therefore, the special game control means 68 counts the number of medals paid out during the 2BB game, and when the number of medals paid out reaches a specified value, controls to end the 2BB game at that time.

(Production control means)
The effect control means 69 controls the output of effects from the above-described effect output devices (the lamp 21, the speaker 22, and the image display device 23).
The production control means 69 selects the production pattern for each game based on the lottery result of the combination by the combination lottery means 61. Particularly in this embodiment, a plurality of types of effect patterns are provided in advance. Then, the effect control means 69 selects any one effect pattern by lottery using software random numbers after the role lottery means 61 is selected by lottery at the start of the game.

  In addition, a plurality of types of production patterns are provided according to the winning combination. For example, a plurality of types of effect patterns are provided for each 1BB win, for a small role win, for a replay win, and for a non-win (no inside or inside).

As for the production pattern, as to the progress of the game, at what timing (when the start switch 41 is operated, when each stop switch 42 is operated, etc.) what kind of production is output (how the lamp 21 is lit) And what kind of sound is output from the speaker 22, what kind of image is displayed on the image display device 23, etc.).
Then, the effect control means 69 controls to output the effect from the effect output device at a predetermined timing according to the selected effect pattern.

In the present embodiment, the game at the time of 2BB winning outputs the same effect as the game at the time of non-winning of the combination. As described above, 2BB is set to a combination of symbols that may be overlooked unless watched carefully.
And if 2BB is won and a special performance is not output in this winning game (if an effect similar to the game when the role is not won is output), the player will be aware that 2BB has won the prize. Can be difficult.

Further, when the transition to the 2BB game is made, the effect control means 69 outputs an effect indicating whether the game after the end of the second BB game is a probability variation game or a normal game during the 2BB game.
Also, as a production, during 2BB game, a plurality of games (for example, 2BB game by winning 2BB-A to 2BB-C, 3 game, 2BB game by winning 2BB-D to 2BB-F, 2 game ) To output continuous effects. Then, control is performed so as to notify whether the game after the end of the second BB game is a probability variation game or a normal game in the game of the last 2BB game (a game that has reached the prescribed number of 2BB games).

Next, the game transition of the first embodiment will be described. FIG. 5 is a diagram showing the transition of the gaming state in the first embodiment.
First, the normal game (not in the inside) is a game in which a lottery of a combination is performed using the combination lottery table 62A, and there is no upper limit on the number of games. If 1BB is won for a normal game (not inside), it becomes a normal game (inside) game. This internal game also has no upper limit on the number of games, and continues until the winning 1BB wins. When the winning 1BB wins, the game shifts to 1BB game. When 1BB is completed, the transfer destination differs depending on the symbol at the time of winning the 1BB game. First, when 1BB-A or 1BB-B wins and shifts to 1BB game, when the 1BB game ends, the game shifts to probability variation game. On the other hand, when 1BB-C wins and shifts to 1BB game, when the 1BB game ends, the game shifts to normal game (non-inside).

In addition, when 2BB is won / winned in a normal game (not inside), the game shifts to 2BB game. When 2BB ends, the transfer destination differs depending on the symbol at the time of winning the 2BB game. First, when 2BB-A, 2BB-C, 2BB-E wins and the game shifts to 2BB game, when the 2BB game ends, the game shifts to probability variation game. On the other hand, when 2BB-B, 2BB-D, 2BB-F wins and shifts to 2BB game, when the 2BB game ends, shift to normal game (non-inside).
When 1BB is won during the probability variation game, the game shifts to the above-described normal game (inside). In addition, when 2BB is won and won during the probability variation game, the game shifts to the above-described 2BB game.

In the slot machine 10 described above, the 2BB winning / winning game does not give a specific performance, and the combination of 2BB symbols does not change much from the normal appearance at first glance. Are often overlooked).
In addition, during the 2BB game, as described above, since the effect of shifting to the probability variation game or the normal game is performed, the player knows that 2BB won the game before the game. It will be.
Even if 2BB does not win or win, the effect of several games in the 2BB game may be output as the effect.

  If 2BB-A, 2BB-C, and 2BB-E have won the game and have shifted to the 2BB game, when the 2BB game ends, the game shifts to the probability variation game. Therefore, from the viewpoint of the player, after the performance between two or three games, the player feels as if the probability-changing game has started without recognizing the trigger for starting the probability-changing game.

On the other hand, if 2BB-B, 2BB-D, and 2BB-F have won the game and have shifted to the 2BB game, the game will be a normal game after the end of the performance.
Note that 2BB-A, 2BB-C, and 2BB-E are set as end conditions of 45, 45, and 30 as the end conditions, respectively. On the other hand, 2BB-B, 2BB-D, and 2BB-F are set with the payout number of 45, 30, and 30 as end conditions, respectively.
For this reason, if 2BB games (games during production output) continue 3 games, the probability of transition to probability variation games is high (2/3), and 2BB games (games during production output) will end with 2 games. For example, the probability of shifting to the probability variation game is low (1/3).

In the probability variation game, the winning probability of replay is increased (1/2), and the game can be continued without reducing the owned medals so much, which is advantageous for the player.
Furthermore, in the probability variation game, the winning probability of 1BB is higher than that in the normal game. In particular, in this embodiment, the winning probability (total value) of 1BB in a normal game is
1/800 + 1/800 + 1/1200
= 1/300
It is.

On the other hand, the winning probability (total value) of 1BB in the probability variation game is
1/200 + 1/200 + 1/300
= 1/75
It is.
Therefore, the winning probability of 1BB in the probability variation game is four times that in the normal game, and the winning expectation of 1BB is higher than that in the normal game.

(Second Embodiment)
Subsequently, a second embodiment of the present invention will be described. In the following description, points unique to the second embodiment different from the first embodiment will be mainly described.
First, in the second embodiment, the combination of symbols of the small role 3 is different from that in the first embodiment. The combination of symbols of the small role 3 of the second embodiment is set to “any”-“any”-“cherry”.
In the second embodiment, “bell” and “cherry” are different in the symbol arrangement on the reel 31.

  FIG. 6 is a diagram showing a symbol arrangement of the reels 31 in the second embodiment. FIG. 6 illustrates only the symbol arrangement of “Bell” and “Cherry” as in FIG. 4, but the symbols such as “R” and “Watermelon” are also arranged in the same manner as in the first embodiment. ing.

First, in FIG. 6, a symbol “cherry” relating to the small role 3 is provided on the right reel 31.
Further, unlike the first embodiment, the “bell” symbol of the left reel 31 is not arranged within five symbol intervals. Therefore, when winning a small combination 1 or a predetermined combination, it is not always possible to win, and it is necessary to operate the left reel 31 with the aim of stopping the “bell” symbol of the left reel 31 on the active line.

  Furthermore, in the second embodiment, during the 2BB game, a lottery of a small combination 1 to a small combination 3 and a replay is performed. Therefore, the combination lottery table 62E has a small combination 1 to a small combination 3 and a winning area for replay. However, as shown in the first embodiment, the 2BB gaming table is used when the small combination 1 to the small combination 3 are won and not. On the other hand, when a replay is won, a replay table (that is, when the replay is won, the same stop position determination table 65 as when a normal replay is won) is used.

Further, in a game other than the replay winning in the 2BB game, the second reel 31 is subjected to the second stop control by software control, and the middle reel 31 and the right reel 31 are subjected to the first stop control using the 2BB game table. .
First, the left reel 31 is controlled by the second stop control so that the symbol of the “bell” related to the small part 1 stops on the active line. The “bell” of the left reel 31 may or may not win when the second stop control is performed. When the left reel 31 is controlled to stop and the “bell” symbol stops on the active line, the middle reel 31 and the right reel 31 use the 2BB gaming table to display the “bell” symbol on the active line. Control to stop.

On the other hand, as a result of the stop control of the left reel 31, when the “bell” symbol does not stop on the active line (for example, the symbols No. 17, 18, and 19 in FIG. 6 stop in the display window). In the 2BB game table, it is determined to display a unique outcome (hereinafter referred to as “chance”).
This chance is an outcome that hardly appears when a winning combination is not won, and may be any outcome as long as it can appear within the range of stop control of the reel 31. For example, the middle reel 31 may stop the “bell” in the middle stage, the right reel 31 may stop the “bell” in the upper stage, and the like.
It should be noted that, in the same way, when the small combination 1 in the normal game is won, control is performed so that the chance eye appears even when the symbol “bell” cannot be stopped on the left reel 31.

In the above control, in the second embodiment, chances appear more frequently during the 2BB game. When a lot of chances are stopped, the player can give a sense of expectation that the game is a 2BB game and may shift to a probability variation game after digesting several games.
In the second embodiment, during a 2BB game, a lottery of a role including a replay is performed, and a small role or a replay may win, so that it is difficult to understand whether the game is a normal game or a 2BB game. Can do.

(Third embodiment)
Subsequently, a third embodiment of the present invention will be described. In the following description, points unique to the third embodiment that are different from the first embodiment will be mainly described.
FIG. 7 is a diagram showing the type of combination, the number of payouts or the end condition, the combination of symbols, and the winning probability in the third embodiment. Moreover, FIG. 8 is a figure which shows the transition of the gaming state in 3rd Embodiment.
As shown in FIG. 7, in the third embodiment, 2BB is not provided, and only 1BB is provided. Thereby, the combination lottery table 62E is not provided.
Here, 1BB-A to 1BB-C are the same as those in the first embodiment. Further, 1BB-D1 to 1BB-D6 are provided as roles corresponding to 2BB-A to 2BB-F of the first embodiment.

When 1BB-D1 to 1BB-D6 wins / wins, 1BB game is executed. This 1BB game is the same as the 1BB game in which 1BB-A to 1BB-C win and shift (the lottery table 62D is used). Accordingly, in the 1BB game, the predetermined combination wins / wins with a high probability. Assuming that a predetermined combination wins during a 1BB game, it will continue 3 times for 1BB games won by 1BB-D1 to 1BB-D3, and 2 times for 1BB games won by 1BB-D4 to 1BB-D6. It will be. Then, during the 1BB game, control is performed so as to output an effect as to whether or not to shift to the probability variation game.
Thus, the present invention can be applied with only 1 BB. Further, during the game of 1BB, the probability that a predetermined combination (“Bell”-“R”-“R”) that is not drawn in the normal game wins is increased. Thereby, the player can know that the 1BB-D1 to 1BB-D6 game is in progress by suddenly winning the predetermined combination. Then, it is possible to give the player a sense of expectation that the game may shift to a probability variation game after several games.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described. In the following description, points unique to the fourth embodiment that are different from the first embodiment will be mainly described.
FIG. 9 is a diagram showing the type of combination, the number of payouts or the end condition, the combination of symbols, and the winning probability in the fourth embodiment. Moreover, FIG. 10 is a figure which shows the transition of the gaming state in 4th Embodiment.
As shown in FIG. 9, in the fourth embodiment, 1BB is not provided, and only 2BB is provided. Here, 2BB-A to 2BB-F are the same as those in the first embodiment.
Further, 2BB-X to 2BB-Z are provided as roles corresponding to 1BB-A to 1BB-C of the first embodiment.

When 2BB-X to 2BB-Z are won, it becomes a game inside 2BB. That is, the combination of symbols from 2BB-X to 2BB-Z is composed of symbols of “red 7” or “blue 7”, and the winning game is not always won.
When 2BB-X to 2BB-Z are won and the game is in the inside of 2BB, the winning lottery table 62C is used as in the first embodiment. When 2BB-X to 2BB-Z win and shift to 2BB game, the content of 2BB game itself is the same as 2BB game of the first embodiment. However, the upper limit number of 2BB games when 2BB-X to 2BB-Z wins is set to 253. When 2BB-X˜ or 2BB-Y wins and a 2BB game is played, the game shifts to a probability variation game after the completion (see FIG. 10). When 2BB-Z wins and a 2BB game is played, the game shifts to a normal game after the completion (see FIG. 10).
Thus, the present invention can be applied only with 2BB.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described. In the following description, points unique to the fifth embodiment different from the first embodiment will be mainly described.
FIG. 11 is a diagram showing the type of combination, the number of payouts or the end condition, the combination of symbols, and the winning probability in the fifth embodiment. Moreover, FIG. 12 is a figure which shows the transition of the gaming state in 5th Embodiment.

The special role of the fifth embodiment is composed of 2BB-X to 2BB-Z provided in the fourth embodiment and 1BB-D1 to 1BB-D6 provided in the third embodiment.
That is, 1BB and 2BB are interchanged with respect to the first embodiment. In this case, the transition of the game content and the game state of the 1BB game and the 2BB game is the same as in the third embodiment and the fourth embodiment.

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 such as the following are possible.
(1) In this embodiment, medals are used as game media. However, the present invention can also be applied to slot machines that use game media other than medals, such as game balls.
(2) The winning probabilities of the respective combinations shown in the present embodiment are examples, and are not necessarily limited to the winning probabilities.

  (3) In this embodiment, the second stop control is executed for the left reel 31 when the winning combination in the 2BB game is not won. However, the present invention is not limited to this. For example, the second stop control may be executed for two reels 31 (for example, the left reel 31 and the right reel 31) or for all the reels 31.

  (4) “Within 5 symbols (within 190 ms)” or “within 2 symbols (within 75 ms)” within the range of the first stop control or the second stop control shown in the present embodiment is an example, It is not limited to this value.

  (5) In the first embodiment, during the 2BB game, an effect indicating whether the game after the end of the 2BB game is a normal game or a probability variation game is output. However, the present invention is not limited to this, and an effect may not be output (the same effect as when a winning combination is not won) may be output. This makes it possible to end the 2BB game without being noticed by the player. This makes it possible to give the player the impression that the probability variation game has started without recognizing the trigger for starting the probability variation game.

  (6) In this embodiment, the left reel 31, the middle reel 31, and the right reel 31 are provided as game reels. However, the present invention is not limited to this, and when a plurality of reel units are provided and the smaller one is the main reel, it is difficult for the player to notice that the combination of symbols corresponding to 2BB (or 1BB) has stopped on the active line. can do. For example, in Japanese Patent Application Laid-Open No. 2005-118330, as a combination of symbols of 2BB (or 1BB), a combination of symbols of the small combination 1 and small combination 2 of the first reel 31 may be employed.
