Description

  The present invention relates to a slot machine that balances a ball while providing a wave to the ball by using overlapping winning of a combination.

In a conventional slot machine, a setting is made so that a plurality of winning combinations may be duplicated, and when a plurality of winning combinations are won, the reels are set to stop control with a predetermined priority (for example, , See Patent Document 1). For example, when BB (Big Bonus) and replay are won simultaneously, the replay winning is given priority first, and then when the replay cannot be won, the special combination is controlled to win. As described above, when the special combination and the replay are set so as to be won simultaneously, when the replay wins, it is possible to give the player a sense of expectation that the special combination may have been won.

A small role A and a small role B for paying out the game medium, and a special role A and a special role B for transferring to the special game A and the special game B, respectively, The lottery is drawn so that the special combination A and the small combination B and the special combination B are combined and the symbols related to the small combination A in at least one reel. On the other hand, in the game in which the small combination A and the special combination A are won by the combination lottery means by arranging the symbol related to the special combination A at a position beyond the range of the reel stop control. , The winning combination is controlled such that one of the winning combinations is won, and at least one of the reels is positioned above the reel stop control range with respect to the symbol related to the small role B. In the game in which the small combination B and the special combination B are won by the combination lottery means by arranging the symbols related to the special combination B, one of the combinations is controlled so as to win a combination when winning the combination. In the at least one reel, the symbols related to the small role A and the symbols related to the special role B are arranged within the range of stop control of the reels, so that the small role B and the special In a game in which the winning combination is won with B, when the stop switch is operated so that the small role A wins, the special role B is controlled so that it is easy to win, and at least one of the reels In a game in which the symbol for the combination B and the symbol for the special combination A are arranged within the range of the reel stop control, so that the combination of the small combination A and the special combination A is won by the combination lottery means. When the stop switch is operated so that the small role B wins, the special role A is controlled so that it is easy to win, and it is inserted from the number of game media paid out in the game where the special role A has won. The total of the net increase by subtracting the number and the expected value of the net increase of the game media in the special game A is set to be smaller than the net increase of the game media in the game won by the small role A. The special The sum of the net increase in game media in the game won by the combination B and the expected value of the net increase in game media in the special game B is less than the net increase in game media in the game won by the small role B When the winning combination of the small role A and the special role A is won by the winning lottery means, and when the winning combination of the small role B and the special role B is doubled, It is provided with the alerting | reporting means which alert | reports that to a player.

According to a second aspect of the present invention, in the slot machine according to the first aspect, the special game A and the special game B are single bonus games in which a special game is performed for only one game.
According to a third aspect of the present invention, in the slot machine according to the first or second aspect, the combination lottery means performs a combination lottery including a replay for replaying, and the winning probability of the replay is A normal game set to X and an RT game in which the winning probability of the replay is set to Y (Y> X), wherein the notification means executes notification in the RT game .

According to a fourth aspect of the present invention, in the slot machine according to the third aspect, the RT game is controlled so as to end when the special combination A or the special combination B wins.
According to a fifth aspect of the present invention, in the slot machine according to the third or fourth aspect, the combination lottery means includes a special combination C for shifting to a special game C that is advantageous to the player. When the special combination C is won by the combination lottery means and the special combination C wins, the special game C is transferred to the special game C and the game after the special game C is set to the RT game. It is characterized by doing.

  The invention of claim 6 is the slot machine according to any one of claims 1 to 5, wherein at least one of the reels, the symbol related to the small role A and the symbol related to the special role B Are arranged adjacent to each other, and in at least one of the reels, the symbol related to the small combination B and the symbol related to the special combination A are arranged adjacent to each other.

(Function)
In the above invention, the special combination A and the small combination A, and the special combination B and the small combination B are set so as to be won in duplicate. When the special combination A and the small combination A, and the special combination B and the small combination B are selected and won, only one of them can be awarded. Here, when the special role A and the small role A are won simultaneously, it is more advantageous for the player to win the small role A than to win the special role A. At the time of overlapping winning, it is more advantageous for the player to win the small role B than to win the special role B.

In addition, in a game in which the stop switch 42 is operated aiming at the small role B, when the special role A and the small role A are repeatedly won, the special role A is set to be easy to win, In a game in which the stop switch 42 is operated aiming at the small role A, when the special role B and the small role B are both won, the special role B is set to be easy to win.
Then, when the small winning combination A and the special combination A are overlapped and the small combination B and the special combination B are selected and overlapped, the notification means notifies that fact.

In claim 1, the special combination A corresponds to SB1 in the present embodiment, and the small combination A corresponds to the small combination 1. Further, the special combination B corresponds to SB2 in the present embodiment, and the small combination B corresponds to the small combination 2.
Furthermore, in claim 3, the winning probability X of replay in the normal game is set to 1 / 7.3 in the following embodiment, and the winning probability Y of replay in the RT game is 1/1. 5 is set.
Further, in claim 5, the special combination C corresponds to 1BB in the following embodiments, and the special game C corresponds to 1BB game.

  According to the first aspect of the present invention, when a winning combination is won, it is possible to increase the payout rate by notifying, and lowering the payout rate by not informing, so a unique game using overlapping winning combinations Can be provided. Further, by controlling the notification period, it is possible to balance the balls while providing waves on the balls.

According to the invention of claim 2, by setting the special game A and the special game B to a single bonus, the net increase of the game media in the special game A and the special game B can be kept low.
Furthermore, according to the invention of claim 3, by executing the notification in the RT game, it is possible to set the payout rate during the RT game to be higher.
Furthermore, according to the invention of claim 4, since the RT game can be ended by winning the special combination A or special combination B, it is possible to set the RT game to end after the notification is completed.

Further, according to the invention of claim 5, the special game C can be set as the RT game start condition (special game C is executed), and the special game C is increased after the number of balls is increased. It is possible to further increase the number of balls after C ends.
Furthermore,

  Furthermore, according to the invention of claim 6, when the special switch A and the small role A are simultaneously elected, when the stop switch is operated so that the small role B wins, the special role A is highly likely. If the stop switch is operated to win the small role A when the special role B and the small role B are selected, the special role B will be won with a high probability. Can do.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an outline of control of the slot machine 10 in the present embodiment. The game control means 60 of the slot machine 10 controls the progress of the game such as the lottery of the combination, the drive control of the reel 31, the payout at the time of winning, and the output of the effect during the game. The game control means 60 is provided on a control board (not shown), and is a CPU that performs calculations, a ROM that stores programs necessary for the progress and production of games, 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 (including a medal slot 43), 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. ing.
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. Similar to the bet switch 40, the medal insertion slot 43 is a part where an actual medal is inserted in order to set an effective line. The insertion of a medal from the medal insertion slot 43 is the same as the operation of the bet switch 40. Is.

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.

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, an “invalid line” is a line that is not set as an effective line among symbol combination lines, and even if a combination of symbols corresponding to any combination stops on that line, This is a line that does not give profits (medal payout etc.). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.
In this embodiment, in all games, three medals are inserted to play a game, and all five symbol combination lines are set as valid lines. That is, in this embodiment, there is no invalid line.
However, a single medal is inserted and a game is performed with one symbol combination line in the middle in the horizontal direction as an effective line, or two medals are inserted and three symbol combination lines in the horizontal direction are enabled. It is also possible to play games as a line.

  FIG. 2 is a diagram showing combinations of combinations of types (combinations drawn by the combination lottery means 61 described later), the number of payouts, and the like in this embodiment. As shown in FIG. 2, special combinations, small combinations, and replays are provided as combinations.

The special role is a role that shifts from the normal game to the special game. In this embodiment, as shown in FIG. 2, 1BB (first type big bonus), RB (regular bonus), and SB (single bonus) are provided as special combinations. 1BB is a role for shifting to 1BB game, which is one of special games, and RB is a role for shifting to RB game, which is another one of special games. Further, the SB is a role for shifting to the SB game which is another one of the special games, and has two types of SB1 and SB2.
Here, although details will be described later, in the present embodiment, the 1BB game and the RB game are games that are advantageous to the player (games that increase medals), but the SB game is not advantageous to the player ( This is a game where medals do not increase.
In addition, although 2BB (2nd type big bonus) is mentioned as another special combination, it is not provided in this 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. And it sets so that the combination of symbols may differ for every 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.

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. 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 the present embodiment, no medal is paid out in a game in which 1BB, RB, SB1, or SB2 wins.

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 RB, excluding SB) are listed as the carry-overs. When winning 1BB or RB, when the reel 31 is stopped, it is controlled to carry over the winning of 1BB or RB after the next game in the game until the combination of symbols corresponding to 1BB or RB stops on the active line The

  In this way, the winnings of 1BB and RB are carried over, while the roles other than 1BB and RB (including SB) are not carried over. In the lottery of a combination, when a combination other than 1BB and RB is won, the winning combination is effective only in the game, and the winning combination 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.

  Note that a game in which 1BB or RB is not won (a game in which 1BB or RB win is not carried over) is referred to as “non-internal”. Also, in the game or the game before it, 1BB or RB is won, but the combination of symbols corresponding to the won 1BB or RB is not stopped on the active line (not winning) (1BB or The game in which the winning of RB is carried over) is called “inside”.

  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 43, and turns on the start switch 41. When the start switch 41 is operated, an effective line is set 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 up and down 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 (the special role, the small role, and the replay described above). The role lottery means 61 is based on, for example, a random number generator for hardware lottery (hardware random number, etc.), a random number extractor for extracting random numbers generated by the random number generator, and a random number value extracted by the random number extractor. 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 value belongs to the 1BB winning area, it is determined to be 1BB winning, and if it belongs to the non-winning area, it is determined not to win.

  The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. 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, and the winning combination has a predetermined winning probability. It is set to a predetermined ratio so that

  FIG. 3 is a diagram illustrating the role lottery tables 62A to 62E of the present embodiment. The combination lottery table 62 includes a specific combination lottery table 62 for each gaming state. Specifically, a role lottery table 62A used for a normal game (inside the inside), a role lottery table 62B used in a normal game (inside), a role lottery table 62C used during the 1BB game and the RB game, SB A role lottery table 62D used during the game and a role lottery table 62E used during the RT game (not inside) are provided.

In FIG. 3, the winning lottery table 62 </ b> A includes duplicate winning of 1BB, RB, SB1 and small role 1 (SB1 + small role 1), overlapping winning of SB2 and small role 2 (SB2 + small role 2), small role 3, In addition, a replay winning area and a non-winning area are provided.
Therefore, SB1, SB2, small combination 1, and small combination 2 are not always won independently, but are always duplicated.

Further, in the combination lottery table 62B, the winning area for the special combination (1BB, RB, SB1 + small combination 1, SB2 + small combination 2) does not exist (set as a non-winning area) as compared with the combination lottery table 62A. Is different. In other words, the special combination is not drawn by lottery.
Furthermore, the winning lottery table 62C is provided with a winning area for a small role 1, a small role 2, and a small role 3, and in particular, the winning area for the small role 3 is set widely.
Furthermore, the winning lottery table 62D is provided with the winning areas of the small role 1, the small role 2, and the small role 3, but the non-winning area is set most widely.

  Furthermore, the winning combination probability 62 of the replay is set higher than the winning combination lottery table 62A. In this embodiment, the winning probability of replay of the winning lottery tables 62A and 62B is 1 / 7.3, but the winning probability of replaying of the winning lottery table 62E is set to 1 / 1.5.

Next, the payout rate will be described.
The payout rate means an expected value of the payout number with respect to the number of inserted medals. When the payout rate is 100% (1), it means that the number of medals inserted and the number of payouts are the same value.
Therefore, when the payout rate is less than 100%, medals will decrease as the game progresses. When the payout rate exceeds 100%, the medals increase as the game continues. Will go.

Here, in this embodiment, the normal game and the RT game (non-notification period to be described later) are also games in which the payout rate is less than 100%. However, the RT game has a higher replay win probability than the normal game, as described above. As a result, the RT game is a game having a higher payout rate than the normal game. In particular, in the RT game of the present embodiment, the winning probability of the combination and the number of payouts are set so that medals are hardly reduced by the progress of the game.
Further, as will be described later, during the RT game notification period, if the stop switch 42 is operated in accordance with the notification, a game state in which the payout rate exceeds 1 (the number of balls to be increased) is entered.

  In the present embodiment, when the 1BB game ends, first, the RT game (notification period) is started. In RT games, since replays are frequently won, a gaming state in which medals are not reduced as much as a normal game due to the progress of the game (especially a gaming state in which medals increase during the RT game notification period). Become. Therefore, the player can wait for the special role to be won during RT game without reducing the medals so much.

Returning to FIG.
In the game until the special combination 1BB or RB is won, until the combination of symbols corresponding to the 1BB or RB stops on the active line (until 1BB or RB wins) It controls to carry over the winning of 1BB or RB after the next game.

  First, the reel control means 64 controls to start rotation of all (three) reels 31 when the start switch 41 is operated. Further, the reel control means 64 determines a stop position determination table, which will be described later, based on the winning lottery result by the winning lottery means 61 when the stop switch 42 is operated and the timing when the stop switch 42 is operated. The stop position of the reel 31 corresponding to the stop switch 42 is determined with reference to 65, and the motor 32 is driven and controlled to stop the reel 31 at the determined position.

  For example, the reel control means 64 controls to stop the reel 31 so that the combination of symbols corresponding to the winning combination is stopped on the effective line within the range of the stop control of the reel 31 in the game won for the winning combination. The reel 31 is controlled to stop so that a combination of symbols corresponding to a combination other than the combination is not stopped on the effective line.

  Here, “within the range of stop control of the reel 31” means within the range of the amount of rotation of the reel 31 (the number of movements of the symbol) from the moment when the stop switch 42 is operated until the reel 31 actually stops. In this embodiment, however, the number is set within 5 symbols from the symbol at the moment when the stop switch 42 is operated. In other words, it means within the range of the stop control time of the reel 31, that is, the time from the moment when the stop switch 42 is operated until the reel 31 actually stops. In this embodiment, the moment when the stop switch 42 is operated. Within 190 ms.

  Thus, any of the symbols up to the number of symbols (5 symbols) within the range of stop control of the reel 31 counted from the symbol at the moment when the operation of the stop switch 42 is detected is a symbol to be stopped on the effective line. When the stop switch 42 is operated, the symbol is controlled to stop at the active line.

  In other words, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated at the time of winning the winning combination, when the symbol related to the winning winning combination does not stop on the effective line, when the reel 31 stops, By controlling the rotational movement of the reel 31 within the “range of control”, the symbol related to the winning combination is controlled to stop as much as possible on the effective line.

  On the contrary, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated when the winning combination is not won, the combination of symbols corresponding to the winning combination is stopped on the effective line. When the reel 31 is stopped, the reel 31 is controlled to rotate and move within the “reel 31 stop control range” so that the symbol combination corresponding to the winning combination is not stopped on the active line.

The stop position determination table 65 determines the stop position of the 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 includes the following 1BB table and the like.

The 1BB table is used on condition that 1BB is won in the game, or 1BB is won in the game before the game and is not won in the game, and the 1BB table is used within the range of the stop control of the reel 31. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to 1 is stopped on the effective line and the combination of symbols corresponding to the role other than 1BB is not stopped on the effective line.
The RB table is the same as the 1BB table described above, and corresponds to a table obtained by replacing “1BB” with “RB” in the 1BB table.

The small role 3 table is used on the condition that the small role 3 is won in the game (which is a game that has not carried over the special role winning), and within the range of the stop control of the reel 31, the small role 3 table is used. The combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to is stopped on the effective line and the combination of symbols corresponding to the role other than the small role 3 is not stopped on the effective line. .
The replay table is the same as the small role 3 table described above, and corresponds to a table in which “small role 3” in the small role 3 table is replaced with “replay”.

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.
In addition, since SB1, SB2, the small combination 1, and the small combination 2 are not won independently, these stop position determination tables 65 are not provided.

  In addition, the SB1 priority SB1 / small role 1 table is used in a game in which the SB1 and the small role 1 are duplicated in the game, and within the range of the stop control of the reel 31, first, a combination of symbols corresponding to SB1. Priority is given to stopping on the effective line, and when the symbol combination corresponding to SB1 cannot be stopped on the effective line, the symbol combination corresponding to the small role 1 is then stopped on the effective line. The combination of symbols when the reel 31 is stopped is determined. Furthermore, when the combination of symbols corresponding to the small role 1 cannot be stopped on the active line, the combination of symbols when the reel 31 is stopped so that the combination of symbols corresponding to any of the roles does not stop on the effective line. Is stipulated.

  The SB2 priority SB2 / small role 2 table is the same as the SB1 priority SB1 / small role 1 table described above, and “SB1” in the SB1 priority SB1 / small role 1 table is replaced with “SB2”. "Is replaced with" Small 2 ".

  In addition, when a small role 3 is won during a game (inside the game) that carries over the special role winning, priority is given to stopping the combination of symbols corresponding to the special role carrying over the winning in the active line, If the combination of symbols corresponding to the special combination cannot be stopped on the active line, the combination of symbols corresponding to the small combination 3 won in the game is then stopped on the effective line. When the combination of symbols corresponding to 3 cannot be stopped on the active line, the combination of symbols when the reel 31 is stopped is determined so that the combination of symbols corresponding to any combination does not stop on the effective line. A position determination table is used.

In addition, when a replay is won during a game that carries over winning of a special role, priority is given to stopping the symbol combination corresponding to the replay won in the game on the active line, and the symbol combination corresponding to replay If it cannot be stopped on the active line, the symbol combination corresponding to the special role carrying over the winning will be stopped on the active line, and further, the symbol combination corresponding to the special role will be stopped on the active line. When the reel 31 cannot be stopped, a stop position determination table that defines the combination of symbols when the reel 31 is stopped is used so that the symbol combination corresponding to any combination does not stop on the effective line.
In addition, since SB1 + small combination 1 and SB2 + small combination 2 are not drawn in the interior, there is no stop position determination table 65 when these combinations are won in the interior.

  Using the stop position determination table 65 described above, the reel stop control means 64, when stopping a combination of symbols corresponding to any of the combinations on the effective line, performs the combination within the range of the stop control of the reel 31. Control is performed so that the symbols constituting the corresponding symbol combination are stopped on the active line.

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 present embodiment. In FIG. 4, only a part of the symbols is shown, but a predetermined symbol is also displayed in a blank part in the diagram, and the illustration is omitted in FIG.

As shown in FIG. 4, on each reel 31, 21 symbols are arranged at equal intervals.
In addition, all the symbols “RP” are arranged on each reel 31 at intervals within 5 symbols. Therefore, symbols of “RP” are arranged on the reel 31 at intervals within the range of the stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). As a result, the “RP” symbol is always controlled to stop at the desired effective line regardless of the position of the reel 31 at the moment when the stop switch 42 is operated. Can do.

Therefore, at the time of winning the replay, the symbol combination corresponding to the selected replay always stops on the active line. In addition, if a replay is won during a game that has been overtaken by a special role, priority will be given to the replay, but the priority replay will always win. There is no.
Furthermore, at the time of overlapping winning of SB1 and small role 1, and when overlapping winning of SB2 and small role 2, with respect to the middle reel 31 and the right reel 31, which position of the reel 31 at the moment when the stop switch 42 is operated is determined. Even so, it is possible to always control to stop the symbol of “RP” to a desired effective line.

Although not shown, all the symbols of “bell” are arranged on each reel 31 at intervals of 5 symbols or less. Accordingly, symbols of “bell” are arranged on the reel 31 at intervals within the range of stop control of the reel 31 (within 5 symbols including the symbol at the moment when the stop switch 42 is operated). As a result, the “bell” symbol is controlled so that the “bell” 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. Can do.
Therefore, when winning the winning combination 3, the combination of symbols corresponding to the winning winning combination 3 always stops on the active line. In addition, when a small role 3 is won during a game in which a special role has been won, priority is given to the special role. However, if the special role does not win, the small role 3 always wins.

  Furthermore, as shown in FIG. 4, the symbol “A” constituting the SB1 of the left reel 31 and the symbol “D” constituting the small part 1 are arranged in the 0th and 11th, respectively. Therefore, both are arranged at an interval of 11 symbols. Here, since the range of the stop control of the reel 31 is 5 symbols as described above, the symbols “A” and “D” are arranged at positions beyond the range of the stop control of the reel 31. Yes.

The reason for this arrangement is to prevent only one of the winning combinations (SB1 or small winning combination 1) from winning when the winning combination of SB 1 and small winning combination 1 is won.
When SB1 and small role 1 overlap, the symbols from No. 16 to No. 18 are displayed in the display window from the moment the symbols from No. 16 to No. 18 are located in the display window (located on any active line). When the stop switch 42 is operated up to the moment of being positioned inside, the 11th symbol “D” stops on any active line.
When the stop switch 42 is operated at the above position, the 0th symbol “A” does not stop at the active line.

In addition, when overlapping winning combination of SB1 and small role 1 from the moment when the symbols from No. 5 to No. 7 are located in the display window (positioned on any valid line), No. 19, No. 20, and No. 0 When the stop switch 42 is operated before the moment when the previous symbols are positioned in the display window, the 0th symbol “A” stops at any of the active lines.
When the stop switch 42 is operated at the above position, the 11th symbol “D” does not stop at the active line.

  Note that when symbols SB1 and small role 1 are overlapped, symbols from No. 8 to No. 10 are placed in the display window (positioned on any valid line) and from No. 6 to No. 8 When the stop switch 42 is operated up to the moment of being positioned within the display window, neither the 0th symbol "A" nor the 11th symbol "D" stops at the active line (in this case, The role is not won).

The same applies to the case where SB2 and small combination 2 are won simultaneously.
When the winning combination of SB2 and small role 2 is won, the symbols from No. 15 to No. 17 are displayed in the display window from the moment the symbols from No. 15 to 17 are located in the display window When the stop switch 42 is operated up to the moment of being positioned inside, the symbol “C” of No. 10 stops at any effective line.
When the stop switch 42 is operated at the above position, the first symbol “B” does not stop at the active line.

In addition, when SB2 and small role 2 are overlapped, the symbols from No. 6 to No. 8 are placed in the display window (positioned on one of the effective lines) from the moment No. 20, No. 0 and No. 1 When the stop switch 42 is operated until the moment when the previous symbols are positioned in the display window, the first symbol “B” stops at any of the active lines.
When the stop switch 42 is operated at the above position, the 10th symbol “C” does not stop at the active line.

  In addition, when the stop switch 42 is operated at the moment when the symbols 7 to 9 are positioned in the display window when the winning combination of SB 2 and the small role 2 is won, the symbols “B” and 10 None of the symbols “C” on the active line stops in this case (in this case, the winning combination is not won).

Furthermore, the symbol “A” constituting the SB 1 and the symbol “B” constituting the small role 2 are arranged adjacent to each other (within the range of stop control of the reel 31 (within an interval within 5 symbols)). Yes.
The reason for this arrangement is to control the SB1 so that it is easy to win when the stop switch 42 is operated so that the winning combination 2 wins the prize when the winning combination of SB1 and the winning combination 1 occurs.

In order for the symbol “B” constituting the small role 2 to stop on the active line, as described above, from the moment when the symbols from No. 6 to No. 8 are located on the active line, No. 20, 0 and 1 The stop switch 42 must be operated until the moment when the symbol is positioned on the active line.
Here, when the player expects that SB2 and small role 2 are won in the game, and the stop switch 42 is operated at the above position, B2 and small role 2 are actually won. At that time, small winning combination 2 wins.

  However, if the player's expectation is wrong and SB1 and small role 1 are won in the game, the stop switch 42 is operated at the moment when the symbols from No. 6 to No. 8 are located on the active line. Then, the symbol “A” related to SB1 does not stop on the effective line (in this case, the combination of symbols corresponding to any combination does not stop on the effective line). In addition, the stop switch 42 is operated from the moment when the other symbols from No. 5 to No. 7 are located on the effective line to the moment when the No. 19, No. 20, and No. 0 symbols are located on the active line. For example, the symbol “A” related to SB1 stops at the active line.

  Similarly, in order for the symbol “D” constituting the small role 1 to stop on the active line, as described above, from the moment the symbols No. 16 to No. 18 are positioned on the active line, No. 9 to No. 11 The stop switch 42 must be operated until the moment when the previous symbols are positioned on the active line.

Here, in the game, when it is predicted that SB1 and small role 1 are won in duplicate, and the stop switch 42 is operated at the above position, SB1 and small role 1 are actually won. At that time, a small winning combination 1 wins.
However, if the player's expectation is wrong and SB2 and small role 2 are won in the game, the stop switch 42 is operated at the moment when symbols 16 through 18 are located on the active line. Then, the symbol “C” related to SB2 does not stop on the effective line (in this case, the combination of symbols corresponding to any combination does not stop on the effective line). Furthermore, if the stop switch 42 is operated between the moment when the other symbols from No. 15 to No. 17 are located on the active line and the moment when the symbols from No. 8 to No. 10 are located on the active line, The symbol “C” related to SB2 stops at the active line.

  As described above, when the stop switch 42 is operated so that the winning combination of SB1 and the small role 1 is won, when the stop switch 42 is operated so that the winning combination of the SB2 and the small role 2 is easy. When the stop switch 42 is operated so as to win the small role 1, SB2 is set so as to be easy to win.

  The stop symbol determination means 66 determines 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 determination means 66 determines a symbol on the effective line by detecting, for example, an angle or the number of steps when the motor 32 is stopped.

  The payout means 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 determination unit 66 and the winning combination is won. In addition, a predetermined number of medals are paid out to the player in accordance with the winning combination, or processing such as credit addition is performed. Further, at the time of replay winning, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

  The special game control means 68 starts the special game (1BB game, RB game or SB game) (transition from normal game to 1BB game, RB game or SB game), during 1BB game, during RB game or SB game And the end of 1BB game, RB game or SB game.

First, when the symbol combination corresponding to 1BB stops on the active line during the normal game, 1BB is won, and the special game control means 68 starts the 1BB game from the next game.
In the 1BB game, the lottery of the combination is performed using the combination lottery table 62C. Therefore, in particular, a gaming state in which the small combination 3 is won with a high probability.

In this embodiment, the end condition for the 1BB game is set such that the number of medals paid out during the 1BB game is 450 or more.
Therefore, in the present embodiment, the special game control means 68 counts the number of medals paid out during the 1BB game, and keeps updating the number of coins paid out for each game.
When the special game control means 68 determines that the counted number of payouts is 450 or more, the special game control means 68 determines that the end condition of the 1BB game is satisfied.

Further, the special game control means 68 shifts from the normal game to the RB game when the symbol combination corresponding to the RB stops on the active line. Also in the RB game, a game is performed using the winning lottery table 62C, and a gaming state in which the small role 3 is won with high probability is achieved.
In the present embodiment, the RB game end condition is set such that the number of winning a winning combination reaches 8 times or the number of games reaches 12 times.
Therefore, in this embodiment, the special game control means 68 counts the number of winnings and the number of games for the winning combination in the RB game, and continuously updates the number of winnings and the number of games for each game. When it is determined that the number of games has been reached or the number of games has reached 12, the CPU determines that the RB game end condition is satisfied.

Furthermore, when the symbol combination corresponding to SB (SB1 or SB2) stops on the active line, the special game control means 68 shifts from the normal game to the SB game. Only one SB game is played.
Further, in the SB game, the role lottery table 62D is used. However, if the role lottery table 62D is used, it is not won with high probability.

Here, in the winning combination lottery table 62D, it is assumed that the winning probability of the small combination 1 is 5%, the winning probability of the small combination 2 is 5%, and the winning probability of the small combination 3 is 10%.
At this time, the expected value (theoretical value) of the number of medals paid out in the SB game is
15 × 5/100 (small role 1) + 15 × 5/100 (small role 2) + 8 × 10/100 (small role 3)
= 2.3.
Therefore, in an SB game, if three medals are inserted and a game is played, the expected value of the number of medals paid out-the number of inserted medals (= difference) is
-0.7 sheets.
Further, since the number of payouts at the time of SB winning is 0, the difference number at the time of winning SB is -3.
Therefore, the difference between the game at the time of SB winning and the SB game is
-3-0.7
= -3.7.

On the other hand, if the small combination 1 wins at the time of overlapping winning of the SB 1 and the small combination 1, the payout number is 15, and the difference number in the game is +12. The same applies to the case where SB2 and small role 2 are won simultaneously.
From the above, when overlapping winning SB1 and small role 1, it is more advantageous to win small role 1, and when overlapping winning SB2 and small role 2, it is more advantageous to win small role 2 It is.

The RT game control means 69 controls the game state after the end of the 1BB game to be set to RT game.
The RT game control means 69 includes an RT flag 69a. The RT flag 69a is a flag referred to for determining whether or not the game is an RT game. When the RT game is executed, the RT flag 69a is turned on, and at the end of the RT game, the RT flag 69a is turned off.

The RT game control means 69 turns on the RT flag 69a after the end of the 1BB game, and sets the gaming state to the RT game.
As described above, in RT games, the winning probability of replay is higher than that of normal games (non-RT games), so the RT game play rate is set higher than the normal game play rate.
This RT game is continued until SB1 or SB2 wins.
If SB1 or SB2 wins during the RT game, the RT flag 69a is turned off, and after the next game, the game shifts to the normal game (not in the inside).
On the other hand, if 1BB is won during the RT game, the RT flag 69a is turned off, and after the next game, the game moves to the normal game (inside).

The effect control means 70 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 effect control means 70 is provided with effect pattern storage means 71, and a plurality of kinds of effect patterns are provided in the effect pattern storage means 71. There are multiple types of performance patterns depending on the winning combination. For example, a plurality of types of effect patterns are provided for each special role winning, small role winning, replay winning, non-winning, and the like.

  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.).

The effect control means 70 selects the effect pattern from the effect pattern storage means 71 based on the lottery result of the role by the role lottery means 61 for each game. In particular, in the present embodiment, at the start of a game or the like, after a combination of lotteries is performed by the combination lottery means 61, one effect pattern is selected by lottery using software random numbers.
Then, the effect control means 70 controls to output an effect from the effect output device at a predetermined timing according to the selected effect pattern.

Furthermore, the effect control means 70 includes a winning symbol notification means 72.
In the RT game, the winning symbol notification means 72 notifies the player of which combination is won when SB1 and small role 1 are overlapped and when SB2 and small portion 2 are overlapped. To do. The notification is content that is advantageous to the player. For example, when SB1 and small role 1 are won in duplicate, aim for “small role 1 (design“ D ”)! ”And“ SB1 (design “A”)! ".

In accordance with the notified contents, the player operates the stop switch 42 so that the small combination 1 wins the prize when the winning combination of the SB 1 and the small role 1 and the small player when the overlapping winning combination of the SB 2 and the small role 2 occurs. The stop switch 42 may be operated so that the combination 2 wins.
And while being informed in this way, winning of SB1 and SB2 can be avoided, so that RT games can be maintained, and winning winning combination 1 and winning combination 2 are surely won. And you can increase the number of medals.

The number of notification games in RT games is arbitrary.
In the present embodiment, at the end of the 1BB game, a lottery using software random numbers is performed to determine the number of notification games. For example, the number of notification games is 30 times with a probability of 10/100, the number of notification games is 50 with a probability of 20/100, the number of notification games is 100 with a probability of 20/100, and so on. The number of notification games is determined by lottery.

Until the RT game is started and a predetermined number of notification games is reached, notification is performed at the time of overlapping winning combination of SB1 and small role 1 and when overlapping winning combination of SB2 and small role 2 (notification period). During the notification period, the winning probability of replay is high, and medals are paid out by winning the small combination 1 and small combination 2, so that the gaming state where the number of medals increases as the game progresses.
When the predetermined number of notification games is reached in the RT game, the notification is not performed in the subsequent RT games (non-notification period). However, even during the non-notification period of the RT game, since the winning probability of replay is high, the game can be performed with almost no decrease in medals.

  In the non-notification period of the RT game, whether or not the winning SB1 or SB2 wins depends on luck. That is, in the non-notification period of the RT game, when SB1 is won, SB1 wins with a probability of about 1/2. Similarly, when SB2 is won, SB2 wins with a probability of about 1/2. When the winning SB1 or SB2 wins, the RT flag 69a is turned off, and the next game shifts to the normal game (non-inside).

As described above, in this embodiment, after the end of the 1BB game, the RT game of the notification period is provided. The RT game in the notification period becomes a gaming state in which medals increase if the stop switch 42 is operated according to the notification. Further, when the notification period ends and the game shifts to the RT game in the non-notification period, the game state is such that medals are hardly decreased (although medals are not increased). However, since notification is not performed during this period, SB1 or SB2 may win. When SB1 or SB2 wins, the RT game is ended and the game shifts to a normal game (game in which the payout rate is less than 1).
Therefore, by using the overlapping winning combination of SB1 and small role 1 and overlapping winning combination of SB2 and small role 2, providing a plurality of gaming states with different appearances, and moving between these gaming states, In addition to providing a wave, the ball can be set to an appropriate value.

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) For example, in this embodiment, a medal is used as a game medium. However, the present invention can be applied to a slot machine using a game medium other than a medal, such as a slot machine (parrot) using a game ball. it can.
(2) In the present embodiment, the SB and the small combination are won in duplicate, but the special combination to be won in duplicate is not limited to SB, and may be another special combination such as RB, for example. If the RB and the small combination are won simultaneously, the net increase in the RB winning and the RB game may be lower than the net increase in the small winning combination.

  (3) The RT game is given as the game to be notified when the SB and the small combination are won simultaneously. Also, the RT game end condition is not limited to the SB winning. Furthermore, the transition to the RT game is made after the end of the 1BB game. However, not limited to this, the transition to the RT game is made after the end of the RB game or when a predetermined condition is satisfied during the normal game. Also good.

  (4) In the present embodiment, as shown in FIG. 4, the symbol “A” and the symbol “B” are arranged adjacent to each other, and the symbol “C” and the symbol “D” are arranged adjacent to each other. However, not limited to this, the symbol “B” for the symbol “A” and the symbol “D” for the symbol “C” may be arranged at least within the range of stop control of the reel 31 (within 5 symbols). That is, it is only necessary that the symbol “A” (or symbol “C”) can be won when the stop switch 42 is operated aiming at the symbol “B” (or symbol “D”).

  (5) In this embodiment, there are two overlapping winnings (overlapping winnings of SB1 and small roles 1 and overlapping winnings of SB2 and small roles 2), but further overlapping overlapping winnings of SB3 and small roles are provided. May be. In this case, the symbol relating to SB1, the symbol relating to SB2, and the symbol relating to SB3 may be arranged at intervals of seven symbols.

  (6) In this embodiment, the number of notification games is determined after the end of the 1BB game. However, the present invention is not limited to this, and the number of notification games may be determined at any time. For example, it may be when 1BB is won or when 1BB is won. Further, the number of notifications may be determined without determining the number of notification games. For example, when the number of notifications is determined to be 20 times, control is performed so that notifications are made until the number of times of winning SB1 and small role 1 and SB2 and small role 2 is reached.
