JP 2006-141654 A

In the slot machine described in Patent Document 1, the progress of the game can be changed depending on the number of game media bets. In order to achieve this, in accordance with the number of game media bets, It is necessary to set a plurality of lottery tables. In addition, since the winning situation of the winning lottery changes due to the change of the lottery table, the mode of reel stop control also changes accordingly. For this reason, in order to change the progress of the game, an increase in storage data and the number of execution control steps are unavoidable, and in the main control circuit with a limited storage capacity and processing speed, a sufficient change in the game situation There is a fear that it cannot be realized.
In addition, since the winning probability of the RT transition combination in the combination lottery is only changed, there is a case where the transition to the RT operating state may not occur, which may impair the player's expectation.

  Therefore, the object of the present invention is to solve the above-mentioned problems, and to increase the player's interest in the game by changing the progress of the game while suppressing the increase in the stored data and the increase in the number of execution control steps. To provide a slot machine.

  In order to achieve the above object, as the slot machine according to the present invention, a predetermined number of game media are inserted, and a plurality of reels displaying a plurality of symbols are rotated and stopped. A slot machine capable of performing a game with a single process, and a role lottery means for performing a role lottery for determining at least one role or out of a plurality of roles including a re-game role by lottery processing; After rotating a plurality of reels on which a plurality of symbols are displayed, a reel control means for performing stop control of the rotated reel according to the result of the winning combination lottery, and winning a winning combination in the winning lottery When the flag is set, and it is determined that the combination of symbols corresponding to the selected winning combination is displayed on the active line and the winning combination is won, the winning process corresponding to the winning combination is performed. A winning process control means, and a re-game control means for performing a control process for executing the next game without inserting the game medium when it is determined by the winning process control means that the re-game player has won. When the predetermined start requirement is reached, the game state is changed to the re-game selection high state in which the winning probability of the re-game player is set to a value higher than normal in the combination lottery, and the re-game selection high state is set. A re-game selection high state control means for releasing the re-game selection high state when a predetermined release requirement is reached after the change, the predetermined start requirement and / or the predetermined release requirement, The display of a specific display symbol on the active line is included, and there are a first gaming state and a second gaming state in which the same reel stop control is performed according to the result of the winning lottery, and the second gaming state In the gaming state, the first Further, the effective line that is not set in the gaming state is set, and the same reel stop control is performed when the lottery result by the winning lottery means is a predetermined result and the predetermined result is set to an arbitrary active line. It is conceivable to perform stop control so that the specific display symbol is displayed on the further effective line that is enabled in the second gaming state while displaying the symbol based on it.

Here, the “game medium” is a medium that is inserted into the slot machine in order to play a game, such as coins, medals, and chips. Moreover, as long as this object can be achieved, the product is not limited to an article, and for example, an electromagnetically acting material such as a magnetic card can be applied.
In addition, “inserting a game medium” includes actually inserting a game medium from a game medium slot provided in the slot machine, etc., and storing it in a storage medium of the slot machine. This includes using a predetermined number of game media credited in advance.

  Here, the “combination” generally includes a “winning role” for performing a “winning game” that makes the game proceed in an advantageous manner for the player, and a “replaying game” in which the game can be re-executed without inserting a game medium. "Re-game combination" for "and a" general combination "for paying out a predetermined number of game media when winning.

“Winning” refers to performing “winning game” in which a game progresses in an advantageous manner for a player when a winning combination is won by lottery and a symbol corresponding to the winning role stops and wins a prize. It is a possible role. The winning combinations include, for example, a big bonus combination (hereinafter referred to as “BB combination”) and a single bonus combination (hereinafter referred to as “SB combination”).
The BB role (sometimes referred to as “1 type BB role”) is a role that is transferred to a BB game (sometimes referred to as “1 type BB game”), which is one of the winning games. A game in which the winning combination is won with a high probability can be continuously performed until a predetermined number of game media payouts (also referred to as “finished number”) is reached. It is also possible to set a plurality of BB games. For example, a plurality of BB games having different winning probabilities and setting of the number of ending games can be provided.
The SB role is a role that shifts to SB game, which is one of the winning games, and this SB game is a hit game that is performed only for one game, and the winning probability of the role in the role lottery is determined by a normal game. This can be the same as the winning probability, or it can be changed from the winning probability in a normal game.

“Re-game” is a “re-game” that can be re-executed without throwing in game media when a symbol corresponding to the re-game player stops and wins a prize. It is also a role that can be carried out. In addition, when a re-gamer wins and wins, the re-game can be performed with the same number of bets as the re-game player is won, or re-play can be performed with a different bet number. You can also.
The “general combination” is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won. Also, when two or more winning combinations are won at the same time (for example, when one of the SB winning combination and the general winning combination is simultaneously winning), it can be regarded as one winning combination.

  In the “lottery” for determining one combination, for example, it is desirable to generate a random number and determine at least one winning combination based on the value. Regarding the generation of random numbers, it is conceivable to use a random number generator or to generate them on software using a computer or the like.

The “reel on which the symbol is displayed” includes a reel that is physically rotated and stopped by a motor or the like, and a reel on the image that is displayed on the display device and is rotated and stopped on the image. It is. The “reel control means” starts rotation of the reel when receiving a signal transmitted based on the start operation of the player, and rotates when receiving a stop signal transmitted based on the stop operation of the player. The stop control of the reel being performed is performed.
In this case, it is possible to set the rotation of all the reels to be started by one start operation, and based on the operation corresponding to each reel, the rotation is set to start only the reel that has been started. It is also possible. Similarly, it is possible to set the rotation of all reels to be stopped by one stop operation, or to set only the reels that have been stopped based on the operation corresponding to each reel. Is possible.

“Corresponding symbol combinations stop” means, for example, that symbols determined corresponding to roles for each reel stop on a predetermined effective line, and predetermined symbols are aligned. . In this case, a case where a symbol to be stopped is defined for all reels is included, and a case where a symbol to be stopped for some reels is also included. The symbols to be stopped can be set to the same symbol for all reels, or different symbols can be set for each reel.
Conversely, “the corresponding symbol combination does not stop” means that the requirement for corresponding to the above “corresponding symbol combination stops” is not satisfied. Therefore, for example, even when the symbols to be stopped on some of the required reels do not stop, “does not stop”. Of course, even when the symbols to be stopped on all the required reels do not stop, it does not stop.

  “Set a flag” means to set a gaming state in which a predetermined winning process can be performed if a combination of corresponding symbols stops and a winning is made when a predetermined winning combination is won in the winning lottery. Meaning and control, the flag is stored in the storage device (RAM) of the control means.

  Examples of “first gaming state and second gaming state” include, for example, a case where the first gaming state is a normal game and the second gaming state is an SB game. Can do. However, the present invention is not limited to this, and any combination of other game modes can be set to the first game state and the second game state as long as the game state can change the active line. it can.

In the present embodiment, the same reel stop control in the first gaming state and the second gaming state displays a symbol based on a predetermined result on an arbitrary active line when the lottery result by the winning lottery means is a predetermined result. This is a control for stopping the reel so that the specific display symbol is displayed on the further active line that becomes effective in the second gaming state. Therefore, when a symbol based on a predetermined result is displayed on the active line, the normal winning process is only performed in the first gaming state, whereas in the second gaming state, Since the specific display symbol is displayed on the active line, the start / release control of the replay selection high state is further performed.
Therefore, it is possible to change the gaming state by changing the effective line without changing the reel stop control, and to change the progress of the game while suppressing an increase in the stored data and the number of execution control steps. Can be expected to increase the player's interest in games.

  As the slot machine according to the present invention, it is further conceivable to use the same lottery table in the combination lottery in the first gaming state and the second gaming state.

  As the slot machine according to the present invention, when there are a plurality of gaming states in which the different further effective lines are set in the second gaming state, and the same symbol is stopped by the same reel stop control, The game state in which the specific display symbol for starting the re-game selection high state is displayed on the further active line, and the specific display symbol for canceling the re-game selection high state on the further active line are displayed. It is considered that there is a gaming state to be played.

  In this embodiment, even in the same second gaming state, there are a gaming state for starting the re-game selection high state and a gaming state for releasing the re-game selection high state, so that the player can change without changing the reel stop control. It can be expected to give thrills and gaming fun and increase the player's interest in games.

  In the slot machine according to the present invention, the common effective line is set in the first gaming state and the second gaming state, a predetermined winning combination is won in the winning lottery, and the same reel stop When the combination of symbols corresponding to the predetermined combination is displayed on the common activated line by the control, the specific display symbol is displayed on the further activated line that is activated in the previous second gaming state. It is thought that it is done.

  In the present embodiment, not only a privilege by a predetermined winning combination, but also a change in the game state depending on the game state, it can be expected to increase the player's interest in the game.

  In the slot machine according to the present invention, when the combination of symbols corresponding to any winning combination in the combination lottery is displayed on the common effective line by the same reel stop control, the second game is always performed. It is conceivable that the reel is arranged in such a manner that the specific display symbol is displayed on the further effective line that becomes effective in the state.

  In this embodiment, when an arbitrary combination wins, in the second gaming state, the player can always change the gaming state that gives expectation and thrill, so the player's interest in gaming is increased. I can expect that.

  In the slot machine according to the present invention, when the reel symbol arrangement is applied, the symbol combination corresponding to the winning combination is displayed on the common effective line in the symbol determination when the reel is stopped. When it is determined that the game is determined to have occurred, the regame selection high state control means may perform start control or release control of the regame selection high state without performing the symbol determination on the further active line.

    In this embodiment, it is possible to perform the start control or release control of the re-game selection high state without performing further symbol determination on the active line, thereby further suppressing an increase in stored data and an increase in execution control steps. While changing the progress of the game.

  In the slot machine according to the present invention, the further active line is formed by changing a part of the common active line, and the replay selection height is changed according to the position of the changed part. It is conceivable that the effective line on which the specific display symbol for starting the state is displayed and the active line on which the specific display symbol for canceling the replay selection high state is determined.

  In this embodiment, by changing a part of the area of the active line, it is possible to set an effective line as a start requirement and a release requirement for the replay selection high state. Reel arrangement that satisfies the requirements can be realized.

  Further, as the slot machine according to the present invention, it is conceivable that the predetermined bet number is different between the first gaming state and the previous second gaming state.

Next, a functional block diagram of control of the slot machine 10 is shown in FIG.
As a control circuit, the main control circuit 100 and the sub-control circuit 200 are electrically connected. The main control circuit 100 is electrically connected to the operating means 300, and is provided in each of the reels 40L, 40C, and 40R. The motors 80L, 80C and 80R are electrically connected. A display device 70, a display lamp 124, and a speaker 64 are electrically connected to the sub control circuit 200.
The stop operation means 310 is composed of the three stop switches 52L, 52C, and 52R, and the operation means 300 is composed of the stop operation means 310, the start switch 50, and the bet switches 32, 34, and 36. The operation means 300 is not limited to a switch, and any means can be applied as long as it generates an operation signal based on an operation using the player's limbs.

<Description of Main Control Circuit 100>
The main control circuit 100 includes a combination lottery means 410, a reel control means 440, a winning process control means 450, a regame control means 460, and a regame selection high state control means 470.
The role lottery means 410 performs a lottery of a winning combination (BB winning combination and MB winning combination, general winning combination, re-playing winning combination) by a winning lottery process. The role lottery means 410 includes, for example, a random number generator 112 (hard random number, etc.) for the role lottery, a random number extraction means 420 that extracts a random number generated by the random number generator 112, and a random value extracted by the random number extraction means 420 And random number determination means 430 for determining the presence / absence of a winning combination and the winning combination. The control processing by the role lottery means 410 is shown in the role lottery processing subroutine (see FIGS. 6 to 7).

The reel control means 440 controls the motors 80L, 80C, 80R by receiving the reel rotation start signal transmitted from the start switch 50, rotates the reels 40L, 40C, 40R, and the stop switch 52L. , 52C, and 52R, control is performed on the reel operation to stop the reels 40L, 40C, and 40R in response to reception of a reel stop signal transmitted from a predetermined time. In the stop control, a symbol combination control is performed to prevent or prevent the stop symbols from being aligned according to the winning combination. The control processing by the reel control means 440 is shown in the reel fluctuation / stop subroutine (see FIG. 8).
When the winning process control means 450 determines that a winning combination or a general combination is won in the winning lottery process, and the winning symbols relating to the stopped symbols determine that all the symbols corresponding to each winning combination have won. A control is performed to carry out a winning game that is advantageous to the player and payout of a predetermined number of game media.
When the re-game control means 460 determines that the symbols corresponding to the re-gamer have been prepared by the winning symbol determination regarding the symbol that has been won by the re-game player in the lottery process, the next game medium is not inserted. Control for playing a game is performed. Further, when the predetermined requirement is satisfied, a re-game selection high state (hereinafter referred to as “RT (abbreviation of replay time)”) set with a higher probability that a re-game player will win in the combination lottery process. It can be set.

  The re-game selection high state control means 470 has an RT operation state (re-game) in which the game mode is set to a higher probability that a re-game player is won by the combination lottery means when a predetermined start requirement is satisfied. After changing to the RT operation state (re-game selection high state), the control process for releasing the RT operation state (re-game selection high state) is performed when a predetermined release requirement is satisfied.

<Description of Sub Control Circuit 200>
The sub control circuit 200 is provided with an image control unit 510, an audio control unit 520, a lamp control unit 530, and an effect control unit 540. The image control means 510 can control the display drive circuit 220 based on the image data received from the effect control means 540 and the like to display a predetermined effect image on the display device 70. The display device 70, the display drive circuit 220, and the image control means 510 may be referred to as image display means.

In addition, the lamp control unit 520 can control the lamp driving circuit 218 based on the lamp lighting data received from the effect control unit 540 or the like to light the predetermined display lamp 124. Further, the audio control unit 530 can control the speaker drive circuit 222 based on the audio data received from the effect control unit 540 and the like, and can emit predetermined audio from the speaker 64.
The effect control means 540 transmits a control signal including effect data to the image control means 510, the lamp control means 520, and the sound control means 530 described above, and performs control processing for implementing a predetermined effect. This control process includes a control process (see FIG. 14) for performing an effect of notifying the winning symbol of the winning combination.

FIG. 14 shows an effect control subroutine for notifying the player of the winning symbol of the general combination when the general combination and the SB combination are simultaneously won during the RT operation.
In the control process described below, the slot machine 10 is activated in advance, and variables used in the main control circuit 100 and the sub control circuit 200 described above are initialized to predetermined values and are in steady operation. Shall.

<Description of main routine>
First, the control process of the main routine will be described with reference to the flowchart of FIG. In this main routine, a control process when a game is performed once, in which one step from when a player inserts a game medium until a plurality of reels displaying a plurality of symbols is rotated and stopped is performed once. Indicates.
First, it is determined whether or not the value of the parameter NRP is greater than 0 (step S10). Here, NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is greater than 0, and replay is not performed when it is 0 or less. Further, as shown in step S510 of FIG. 11, when the re-gamer is won and won, 1 is input as the value of NRP.

  If it is determined in step 10 that the value of NRP is 0 or less (NO), it is determined that no re-game is performed, and then it is determined whether or not a game medium is inserted (step). S12). If it is determined in this determination that a game medium has been input (YES), the process proceeds to step S18, and the input number counted by a game medium counter (not shown) installed below the game medium input port 38 is obtained. The bet number is detected (step S18). However, when the number of game media exceeding the predetermined number of bets (specified number) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits. In the present embodiment, the prescribed number is 3 for normal games, 2 for SB1 games, and 1 for SB2 games.

  If it is determined in step S12 that no game medium is inserted (NO), the process proceeds to step S14 to determine whether there is a credited game medium (step S14). If it is determined in this determination that there is no credited game medium (NO), the process returns to step S12 again, and the determination processes in steps S12 and S14 are repeatedly executed.

  If it is determined in step S14 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S16). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34, or 36. When it is determined that the bet operation signal has not been received (NO), the process returns to step S12 again, and the determination process from step S12 to step S16 is repeatedly executed. If it is determined in step S16 that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S18). In either case of inserting a game medium or using a credited game medium, the detected bet number is stored in the RAM 110 as a new bet number, and when using a credited game medium, The number of credits of the game medium is reduced by the number of detected bets (step S20), and the process proceeds to step S24.

  If it is determined in step S10 that the value of NRP is greater than 0 and the game is in the replaying state (YES), 0 is input to the value of NRP to cancel the replaying state (step S22), and step S10. Without performing the process of step S20, the same bet number as the bet number in the previous game is set, and the process proceeds to step S24. That is, when it is determined that the game is in the re-gaming state, the game can be performed without newly inserting a game medium or consuming the credited game medium. In this embodiment, the bet number in the replay is set to the same bet number as in the previous game, but it is also possible to set a bet number different from the bet number in the previous game. .

Thus, the game start state is set, and in step S24, a role lottery processing subroutine is performed (step S24). In this combination lottery processing subroutine, combination lottery processing by the combination lottery means 410 is performed, and flag-on processing for turning on the BB flag, the SB flag, the replay flag, and the general combination flag is performed according to the winning combination. Details of this subroutine will be described later with reference to the flowcharts of FIGS.
Subsequent to the combination lottery processing subroutine (step S24), based on the result of the combination lottery, the reel variation and stop subroutine (step S26) performs control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, and 40R are rotated. ) Is performed. This reel fluctuation / stop subroutine is performed by the reel control means 440, and details of this subroutine will be described later with reference to the flowchart of FIG.

Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and based on the determination result, a flag-off / RT setting processing subroutine (step S28) for performing flag-off processing, RT setting processing, etc. Done. The details of this subroutine will be described later with reference to the flowcharts of FIGS.
Then, a payout process (step S30) for paying out a predetermined number of game media corresponding to the winning game based on the winning lottery and winning symbol determination is performed. In the payout process, it is possible to actually pay out the game media from the game media payout outlet 62, or to credit a predetermined number of game media instead of paying out.

  One game is completed by the control process as described above. By repeating the control process shown in this main routine, the player can play a plurality of times.

<Role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S24 of the main routine will be described in detail with reference to the flowcharts shown in FIGS.
First, it is determined whether a start switch ON signal has been received (step S40). The start switch ON signal is a signal transmitted by the operation means 300 when the player operates the start switch 50. Based on this signal, the reel control means 440 performs control for starting the rotation of the reel. This is performed (see step S134 in FIG. 8).
If it is determined in this determination that the start switch ON signal has not been received (NO), the determination processing in step S40 is repeated. In other words, the player waits for the game to start until the player operates the start switch 50.

If it is determined in step S40 that the start switch ON signal has been received (YES), it is next determined whether or not the value of the parameter NBB is greater than 0 (step S42). Here, NBB is a parameter that determines whether or not to play a BB game, and is set so that a BB game is played when it is larger than 0 and a BB game is not played when it is 0 or less. Further, as shown in step S504 in FIG. 13, when the BB combination is won and won, 1 is input as the value of NBB.
If it is determined in step S42 that NBB is greater than 0 (YES), the BB operation general lottery table stored in the ROM 108 is read (step S44), and the process proceeds to step S48. Here, FIG. 15 shows an example of the general lottery table during BB operation.

In the BB operation lottery table, four types of symbol numbers 1 to 9, nine general roles, and a deviation of symbol number 10 are set.
The general roles 1A to 1B having the symbol numbers 1 to 2 are set to win if the winning probabilities in the role lottery are 1/250 and the combination of symbols shown in FIG. 15 stops on the active line. Yes. The general roles 2A to C having the symbol numbers 3 to 5 are set to win if the winning probability in the role lottery is 1/300 and the combination of symbols shown in FIG. 15 stops on the active line. Yes.
The general combination 3 with the symbol number 6 is set to win if the winning probability in the combination lottery is 1 / 1.03 and the combination of symbols shown in FIG. 15 stops on the active line. Therefore, during the BB game, the possibility of winning the general combination 3 in the combination lottery is very high.
The general roles 4A to C of the symbol numbers 7 to 9 are set to win if the winning probability in the role lottery is 1/500 and the combination of symbols shown in FIG. . In addition, the probability of the symbol number 10 coming off is about 1/195, which is a low value.

  Returning to the description of the flowchart of FIG. 6, after reading the general lottery table during BB operation in step S44, the process proceeds to step S52. Next, when it is determined in step S42 that the value of NBB is 0 or less (NO), it is next determined whether or not NRT is a value greater than 0 (step S44). Here, the NRT is a parameter that determines whether or not the game state is an RT operation state (replay selection high state) in which a possibility that a replay is won in the role lottery is higher.

  NRT is set to 0 in the initial state, and when the start requirement of the RT operation state is satisfied, specifically, when the RT start symbol stops on the active line during SB game, the value of NRT 1 is input (see step S406 in FIG. 11). In the RT operation state, when the RT operation state release requirement is satisfied, specifically, when the RT release symbol stops on the active line during the SB game, 0 is input to the NRT value ( Step S412 in FIG. 11). Although not shown in the flowchart, it is also possible to set the RT operation state to end when a predetermined number of games have been consumed in the RT operation state.

If it is determined in step S44 that the value of NRT is greater than 0 (YES), the RT operation general lottery table stored in the ROM 108 is read (step S46). Here, an example of the general lottery table during RT operation is shown in FIG.
In the RT operation general lottery table, four types of symbol numbers 1-9, nine general roles, a re-playing role of symbol number 10, two types of symbol numbers 11-14, four SBn roles (n = 1a to 1c, 2), the BB combination of symbol number 15 and the deviation of symbol number 16 are set. In addition, when compared with the BB non-operating general lottery table (see FIG. 18) used in the normal gaming state, the set role and the symbol are the same, but the winning probability of the re-game player with the symbol number 10 is In the RT lottery table at the time of RT operation, a larger value is set than in the general lottery table when the BB is not operated. Hereinafter, the RT lottery table for RT operation will be described in the order of symbol numbers.

  For the general roles 1, 2, and 4 of the symbol numbers 1 to 5 and 7 to 9, both the symbol and the winning probability are set to be the same as the above-described general lottery table for BB operation (see FIG. 15). However, for the general combination 3 of the symbol number 6, although the symbol is the same, the winning probability is 1/5, which is compared with the general lottery table (1 / 1.03) at the time of BB operation shown in FIG. Is set low. It should be noted that all symbols of symbol numbers 1 to 9 are set to be the same as the RT non-operating general lottery table (see FIG. 17), which will be described later, and symbols and winning probabilities.

The re-game combination with symbol number 10 is set to win if the winning probability in the combination lottery is ½, and the combination of symbols shown in FIG. 15 stops on the active line. It is set higher than the winning probability (1 / 7.3) of the re-gamer in the general game table (see FIG. 17) when the BB is not operated, which will be described later.
In addition, the SB 1A to 1C combination of symbol numbers 11 to 13 is set to win if the winning probability in the combination lottery is 1/180 and the combination of symbols shown in FIG. 16 stops on the active line. ing. Therefore, the total of the winning probability of the SB1 combination is 1/60, and when each SB1A to 1C combination wins, the SB1 game is performed in the next game. Further, the SB2 combination with the symbol number 14 is set to win if the winning probability in the combination lottery is 1/10 and the combination of symbols shown in FIG. 16 stops on the active line. When the SB2 combination wins, the SB2 game is performed in the next game.
Further, in the general lottery table for RT operation (see FIG. 16) and the general lottery table for BB non-operation (FIG. 17), the general combination 1A of symbol number 1 and the SB1A combination of symbol number 11 are won simultaneously. The number is set so that four general combination 2B and symbol number 14 SB2 combination are won simultaneously.

The BB combination with symbol number 15 is set to win if the winning probability in the combination lottery process is 1/600 and the combination of symbols shown in FIG. 16 stops on the active line. The winning symbols and winning probabilities for the SBn combination and the BB combination are the same as those in the general lottery table (see FIG. 17) when the BB is not operating, which will be described later. Therefore, as is clear from comparison between FIG. 16 and FIG. 17, the probability of winning in the re-playing role drawing is set higher at the RT operation than in the normal gaming state. The winning combinations are set exactly the same. The probability of loss (about 1 / 6.34) is set to be lower than that in the normal gaming state because the probability that the re-gamer will win is set higher.
In the RT operation state, when the SBn combination of symbols 11 to 14 wins and wins, SB1 game or SB2 game is played in the next game, but in this embodiment, the SB game-specific lottery table is The role lottery is performed using the same RT operation general lottery table (see FIG. 16).

Returning to the description of the flowchart of FIG. 6, after reading the RT lottery table at RT operation in step S46, an RT information signal is transmitted to the sub-control circuit 200 (step S48), and the process proceeds to step S52. Note that the RT operation signal transmitted to the sub control circuit 200 in step S48 is used in the determination process (see FIG. 14) in step S800 of the effect control subroutine.
Next, returning to the determination in step S44, if it is determined that the value of NRT is 0 or less (NO), the general lottery table when the BB is not operating stored in the ROM 108 is read (step S50). Proceed to step S52. Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  The BB non-operating general lottery table is a lottery table used in a normal gaming state. The four types of symbol numbers 1 to 9, nine general symbols, the re-game symbol of symbol number 10, and symbol numbers 11 to 14 are used. The four types of SBn combination, the BB combination of symbol number 15, and the deviation of symbol number 16 are set. Compared with the above-mentioned RT operation general lottery table (see FIG. 16), the winning probability of the re-gamer with the symbol number 10 is set as low as 1 / 7.3. Both the winning probabilities are the same as those in the general lottery table during RT operation (see FIG. 16). In addition, the probability that the symbol number 16 is off is about 1 / 1.92, and the winning probability of the re-gamer is set lower than the general lottery table during RT operation (see FIG. 16), The probability of loss is high.

In the normal game, when the SBn role of the symbol numbers 11 to 14 is won and won, the SB1 game or the SB2 game is performed in the next game. In this embodiment, the lottery table unique to the SB game is The role lottery is performed using the same general BB non-operating lottery table (see FIG. 17). As described above, in this embodiment, the winning probability in the role lottery does not change in the SB game even during the RT operation and in the normal game.
In the present embodiment, when a winning symbol is displayed on the central horizontal effective line (middle / middle / middle) L1, the activated line (middle / middle / middle) L2A is always valid only during the SB1 game. The RT start symbol is displayed on the active line (middle / middle / bottom) L2B which is valid only during the SB2 game, and the reel symbol arrangement is such that the RT release symbol stops. The detailed description of the reel symbol arrangement will be described later with reference to FIG.

As described above, after the lottery table corresponding to the state of the game is read out, the lottery for acquiring the random number and performing the lottery determination is performed (step S52). Specifically, random numbers generated by the random number generator 112 are extracted by the random number extraction means 420, and the random number determination means 430 compares the extracted random numbers with the read lottery table and determines the winning.
Subsequently to FIG. 6, the process proceeds to FIG. 7, and it is determined whether or not the BB combination is won as a result of the lottery determination (step S <b> 70). In this determination, if it is determined that the BB combination is won (YES), the BB combination flag is turned on and stored in the RAM 110 (step S72), and the process proceeds to step S86.

If it is determined in step S70 that the BB combination is not won (NO), it is next determined whether or not the SBn combination (n = 1A to C, 2) is won (step S74). . In this determination, if it is determined that the SB combination is won by the combination lottery (YES), the SBn flag corresponding to each SBn combination is turned on and stored in the RAM 110 (step S76), and the process proceeds to step S86.
If it is determined in step S74 that the SBn combination is not won (NO), it is next determined whether or not the re-game combination is won (step S78). If it is determined in this determination that the re-gamer is won by the role lottery (YES), the re-game flag is turned on and stored in the RAM 110 (step S80), and the process proceeds to step S86.
If it is determined in step S78 that the re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S82). In this determination, if it is determined that the general combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step S84), and the process proceeds to step S86.

If it is determined in step S82 that the general combination has not been won (NO), the lottery determination result is determined to be out of order, a predetermined control process at the time of out is performed, and the process proceeds to step S86. move on.
After performing a series of processing related to flag-on as described above, in step 86, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used for the reel fluctuation and stop subroutine described later. This data is stored in the RAM 110 (step S86).
Next, as a result of the above-described lottery, that is, a winning lottery information signal including information on winning or out of winning is transmitted to the sub-control circuit 200 (step S88), and this subroutine is finished. The combination lottery information signal transmitted to the sub control circuit 200 in step S88 is used for the determination process (see FIG. 14) in step S802 of the effect control subroutine.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the above-described combination lottery processing subroutine (step S24) is completed, a reel fluctuation and stop subroutine (step S26) is then performed. Next, the reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.
First, the symbol number and control symbol data stored in step S86 of FIG. 7 are read (step S130). Then, it is determined whether or not a predetermined shortest time has elapsed (step S132). If it is determined in this determination that the shortest time has not elapsed (NO), the determination process in step S132 is repeatedly executed. That is, the rotation of the reel, which is the next process, cannot be started until the shortest time has elapsed. By this control, the number of games played in a certain time is controlled to be within a predetermined number.

If it is determined in step S132 that the shortest time has elapsed (YES), the start switch ON signal has already been received (see step S40 in FIG. 6). Transmission to the drive circuit 114 starts rotation of the motors 80L, 80C, 80R, and rotates the reels 40L, 40C, 40R (step S134).
Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S136). In this determination, if it is determined that the rotation of the reel has not yet reached the constant speed rotation (NO), the determination processing in step S136 is repeated. That is, the reel stop control, which is the next step, cannot be performed until the rotation of the reel reaches a constant speed.

If it is determined in step S136 that the reel is rotating at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S138). Here, the reel stop signal is a signal transmitted by the operation means 300 when the player pushes any one of the stop switches 52L, 52C, 52R.
If it is determined in step S138 that the reel stop signal has been received (YES), the reel symbol combination control (stop control) corresponding to the stop switch that has transmitted the reel stop signal is performed (step S140). Proceed to step S142.
Here, the symbol combination control in step S140 will be described in more detail. When the stop switch 52L for the left reel is pushed, the reel control means 440 performs step S140 for the motor 80L that rotates the left reel 40L. The stop control is performed. Similarly, when the stop switch 52C for the middle reel is pushed, the stop control in step S140 is performed for the motor 80C that rotates the middle reel 40C, and the stop switch 52R for the right reel is pushed. In this case, the stop control in step S140 is performed for the motor 80R that rotates the right reel 40R.

The symbol combination control (stop control) is based on the symbol number and control symbol data read in step S130, and the frame when the reel stop signal is received is the first frame, the reel is slid up to the fifth frame, and the range. The motor stop control is performed so as to stop or not stop a predetermined symbol.
More specifically, in the present embodiment, when any combination is won in the lot drawing, the reel is slid to a maximum of the fifth and the stop control is performed so that the symbol corresponding to the winning combination is displayed on the active line. (Retraction control) is performed, and stop control (kicking control) is performed so that symbols corresponding to the winning combination are not displayed on the active line. Here, in the normal game, only the central horizontal line L1 (middle, middle, and middle) is an effective line, but in the SB1 game, in addition to the middle horizontal line L1 (middle, middle, and middle), the line (middle -Middle / Upper L2A is also an effective line, and in SB2 games, in addition to the central horizontal line L1 (Middle / Middle / Middle), the line (Middle / Middle / Lower) L2B is also an effective line.
With this pull-in control, when a symbol corresponding to an arbitrary winning combination other than the BB combination is displayed on the central horizontal effective line L1, the effective line (medium / middle / upper) is always effective only during the SB1 game. ) The RT start symbol is displayed on L2A, and the reel symbol arrangement is such that the RT release symbol is always displayed on the active line (middle / middle / bottom) L2B that is valid only during SB2 games. (See FIG. 18). A more detailed description will be given later.

If it is determined in step S138 that the reel stop signal has not been received (NO), the control proceeds to step S142 without performing control related to the stop. In step S142, it is determined whether all reels have stopped (step S142).
If it is determined by this determination that all reels are not stopped (NO), the process returns to step S138 again, and the control processing from step S138 to step S142 is repeated. If it is determined in step S142 that all reels have stopped (YES), this subroutine is terminated.
As described above, every time the reel stop signal is received, the process of performing symbol combination control (stop control) of the corresponding reels is repeated until all reels stop.

<Explanation of Winning Determination and Flag Off Processing Subroutine>
Next, in the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S26) is completed, a flag-off / RT setting processing subroutine (step S28) is performed. The flag off / RT setting processing subroutine will be described in detail with reference to the flowchart shown in FIG.
First, it is determined whether or not the game state has an NBB value greater than 0 (whether or not a BB game is being played) (step S160). If it is determined in this determination that the value of NBB is greater than 0 (YES), the BB gaming process subroutine (step S162) is performed, and this subroutine is terminated. A detailed description of the BB game processing subroutine will be described later with reference to FIG.

If it is determined in step S160 that the NBB value is 0 or less (NO), it is next determined whether or not the game state is greater than 0 (ie, SBn game is in progress). (Step S164). If it is determined in this determination that the value of NSB is greater than 0 (YES), an SB gaming process subroutine (step S166) is performed, and this subroutine is terminated. The detailed explanation of the SB game processing subroutine will be described later with reference to FIG.
If it is determined in step S164 that the NSB value is 0 or less (NO), it is next determined whether or not there is a winning combination (step S168). If it is determined in this determination that there is a winning combination (YES), a normal / RT gaming process subroutine (step S170) is performed, and this subroutine is terminated. Details of the normal / RT game processing subroutine will be described later with reference to FIG.

  If it is determined in step S168 that there is no winning combination (NO), this subroutine is terminated as it is. Hereinafter, a detailed description of the subroutine shown in steps S162, S166, and S170 will be given.

<Description of processing subroutine during BB game>
First, FIG. 10 shows a detailed explanation of the BB game processing subroutine (see step S162) executed when it is determined that the BB game is being played in step S160 in the winning determination and flag off processing subroutine (see FIG. 9). This will be described with reference to the flowchart shown.
First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S300). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S302). If it is determined in this determination that no winning is made (NO), if the general combination flag is ON, the flag is turned OFF (step S304), and the process proceeds to step S310.

If it is determined in step S302 that there is a winning (YES), the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110 (step S306). This data is used as a BB game end condition, and when the payout number reaches a predetermined number, the BB game is ended. Then, the general combination flag is turned off (step S308), and the process proceeds to step S310.
In step S310, it is determined whether or not the BB game end condition has been achieved (step S310). If it is determined in this determination that the BB game end condition has been achieved (YES), 0 is input to the value of NBB to release the BB game state (step S312), and this subroutine is ended.
If it is determined in step S310 that the BB termination condition has not been achieved (NO), the BB gaming state is not canceled and the present subroutine is terminated.

<Description of processing subroutine during SB game>
Next, in the flag off / RT setting processing subroutine (see FIG. 9), a detailed explanation of the SB gaming processing subroutine (see step S166) executed when it is determined in step S164 that the NSB value is larger than 0 is shown in FIG. This is done using the flowchart shown in FIG.
First, it is determined whether the value of NSB is 1 (step S400). In this determination, if it is determined that the NSB value is 1 (YES), that is, that the SB1 game is being played, then the central horizontal line (middle / middle / middle) L1 and the line (middle / middle / middle) Top) A winning symbol determination is performed using L2A as an active line (step S402).

Next, a winning / non-winning processing subroutine (step S404) for performing predetermined control processing is performed according to the case where each winning combination has won or not, and the process proceeds to step S406. Details of the winning / non-winning processing subroutine will be described later with reference to FIG.
Next, in step S406, it is determined whether or not the BB combination has won (step S406). If it is determined in this determination that the BB combination has won (YES), the process proceeds to step S422.

If it is determined in step S406 that the BB combination has not won (NO), it is next determined whether or not the RT start symbol is displayed on the above-mentioned effective line (step S408). If it is determined in this determination that the RT start symbol is not displayed on the active line (NO), the process proceeds to step S422.
If it is determined in step S408 that the RT start symbol is displayed on the active line (YES), 1 is input to the value of the parameter NRT, and a control process for starting the RT operating state is performed ( The process proceeds to step S410) and step S422. As will be described later, except for the case of winning the BB role, when the symbol corresponding to any winning combination is displayed on the central horizontal effective line (middle / middle / middle) L1 by the pull-in control, SB1 The RT start symbol is always displayed on the effective line (medium / middle / up) L2A which is valid only during the game.

  Therefore, in this embodiment, it is determined whether or not the RT start symbol is displayed on the active line (medium / middle / up) L2A, but the symbol corresponding to any winning combination except the BB role is displayed. When displayed on the center horizontal effective line (middle / middle / middle) L1, the display symbols on the valid line (middle / middle / up) L2A are not determined (that is, the determination process in step S408 is omitted). The RT operation start control process (the control process of step S410) can also be performed. Thereby, the number of control steps can be reduced.

<< Description of RT start design >>
The above contents will be described in more detail with reference to FIGS. FIG. 18 shows the reel symbol arrangement applied to the left, middle, and right reels. FIG. 19 starts the RT operation state when displayed on the active line (the game state is changed from normal game to RT). It is a table | surface which shows RT start symbol (it transfers to an operation game).
As apparent from FIG. 18 and FIG. 19, in a normal game, any combination other than the BB combination (specifically, the general combination 1A to 1B, 2A to 2C, 3, 4A to 4C, the replay combination, SB1A to When the C, 2nd role: see FIG. 17) is displayed on the central horizontal active line (middle, middle, and upper) L1, the RT start symbol shown in FIG. 19 is always valid only during SB1 game. (Middle / Middle / Top) 2A is displayed.

For example, when a winning combination “Red 7 / Red Cherry / Red Cherry” is displayed on the central horizontal effective line (middle / middle / middle) L1 by the pull-in control after winning the general role 1A in the role lottery, The RT start symbol “any (red 7), red cherry replay” is displayed on the effective line (middle, middle, top) L2A.
In other words, the RT start symbol may be any symbol on the left reel, the same symbol as the winning symbol on the middle reel, and the right reel always has a symbol that is one above the winning symbol (the frame number is 1) in the reel symbol arrangement. As shown below, refer to Figure 18). When any winning combination wins (except for the BB combination), the RT start symbol is always on the active line (middle / middle / up) L2A. Will be displayed.

  Returning to the description of the flowchart again, if it is determined in step S400 that the value of NSB is not 1 (NO), that is, SB2 is being played (NSB = 2), then the central horizontal line (middle The winning symbol determination is performed with the middle (middle / medium) L1 and the line (middle / middle / bottom) L2B as effective lines (step S412).

Next, a winning / non-winning processing subroutine (step S414) for performing predetermined control processing is performed according to the case where each winning combination has won or not, and the process proceeds to step S416. Details of the winning / non-winning processing subroutine will be described later with reference to FIG.
Next, in step S416, it is determined whether or not the BB combination has won (step S416). If it is determined in this determination that the BB combination has won (YES), the process proceeds to step S422.

If it is determined in step S416 that the BB combination has not won (NO), it is next determined whether or not the RT release symbol is displayed on the above-mentioned effective line (step S418). If it is determined in this determination that the RT release symbol is not displayed on the active line (NO), the process proceeds to step S422.

If it is determined in step S418 that the RT release symbol is displayed on the active line (YES), 0 is input to the value of the parameter NRT, and a control process for releasing the RT operation state is performed ( Step S420) and the process proceeds to Step S422.

  As will be described later, when a symbol corresponding to an arbitrary winning combination is displayed on the central horizontal effective line (middle / middle / middle) L1 by the pull-in control except for the winning of the BB combination, SB2 game The RT release symbol is always displayed on the effective line (middle, middle, and lower) L2B that is valid only during the period. Therefore, in the same way as above, when a symbol corresponding to any winning combination except the BB combination is displayed on the central horizontal effective line (middle / middle / middle) L1, the activated line (middle / middle / lower) L2B Without performing the above display symbol determination (that is, omitting the determination processing in step S418), the RT operation release control processing (control processing in step S420) can be performed. Thereby, the number of control steps can be reduced.

<< Explanation of RT release symbols >>
The above contents will be described in more detail with reference to FIGS. FIG. 18 shows the reel symbol arrangement applied to the left, middle and right reels, and FIG. 20 cancels the RT operation state when displayed on the active line (the game state is changed from the RT operation game to the normal game). This is a list of RT release symbols to be transferred to.
As apparent from FIG. 18 and FIG. 20, any combination other than the BB combination in the SB2 game (specifically, the general combination 1A to 1B, 2A to 2C, 3, 4A to 4C, the re-game combination, SB1A to C) When the second role (see FIG. 17) stops on the central horizontal line (middle / middle / middle) L1, the RT release symbol shown in FIG. 20 is always valid only during the SB2 game (middle / middle / middle). (Middle / Bottom) Displayed on 2B.

For example, when the winning combination “Right 7 / Red Cherry / Red Cherry” is displayed on the central horizontal line (Medium / Medium / Medium) L1 by reel stop control, On the effective line (middle / middle / bottom) L2B, RT release symbols “any (red 7), red cherry, red 7”, “any (red 7), red cherry, elephant”, and “any (red 7) -"Red cherry / tree" is displayed.
In other words, the RT release symbol may be any symbol on the left reel, the same symbol as the winning symbol on the middle reel, and the right reel on the reel symbol arrangement one symbol below the winning symbol (frame number is 1). As shown in Fig. 18, the RT cancellation symbol is always displayed on the line (middle / middle / bottom) L2B when any winning combination wins (excluding the BB combination). Will be.

<< Explanation regarding change of active line >>
As described above, in this embodiment, in the normal game and the SBn game (n = 1 to 2), the same lottery table is used, and the reel stop control according to the result lottery result is also the same. However, in the SB1 game, in addition to the central horizontal line (middle / middle / middle) L1 common to the normal game, the line (middle / middle / middle) L2A is added to the active line. Further, in the SB2 game, in addition to the central horizontal line (middle / middle / middle) L1 common to the normal game, the line (middle / middle / lower) L2B is added to the active line. Only by changing (adding) such an active line, the progress of the game can be greatly changed.

This will be described in more detail with reference to FIG. 21 (a) to 21 (c) show that the symbol corresponding to the general combination 1A won in the combination lottery is the central horizontal effective line (middle / middle / middle) as a result of performing the same pull-in control using the same lottery table. Middle) Shown when stopped at L1.
Here, (a) in the normal game of the case 1, only the central horizontal line (medium / medium / medium) L1 becomes an active line (see colored portion), so that the game medium corresponding to the winning of the general role 1A Only the payout process is performed.
On the other hand, in (b) SB1 game of case 2, in addition to the central horizontal line (middle, middle, middle) L1, the line (middle, middle, upper) L2A is also an effective line (see colored part), In addition to the game medium payout process corresponding to the winning of the general combination 1A, the start control of the RT operation state (control to shift from the normal game to the RT game) is performed.
In addition, (c) during the SB2 game of case 3, in addition to the central horizontal line (middle, middle, middle) L1, the line (middle, middle, lower) L2B is also an effective line (see colored portion), In addition to the game medium payout process corresponding to the winning of the general combination 1A, the RT-actuated game release control (control from RT game to normal game) is performed.

Further, in order to enable the player to easily grasp the effective line during the SBn game, for example, the sub-control circuit 200 can indicate the effective line using the display device 70 or the like. In this case, when a special symbol such as an RT start / release symbol is displayed on the active line, the player can be notified of the special symbol being stopped by blinking the active line. In an ordinary game, such an effective line need not be displayed.
Further, as described above, when the winning symbol is displayed on the central horizontal effective line (middle / middle / middle) L1, the main control circuit 100 adds the activated line (middle / middle / upper) in the SBn game. / Lower) The RT operation start / release control process can be performed without performing the display symbol determination on L2A / B. Even in this case, the sub-control circuit 200 performs a control process based on the winning lottery information signal received from the main control circuit 100, and an effective line (medium / medium / (Up / Down) blinking display etc. can be implemented.
Since the display of the effective line for indicating the stop of the special symbol as described above is different from the winning combination winning combination in the winning lottery, the degree of freedom with respect to the display mode is high, for example, the active line flashes intensely. This can be shown in an arbitrary manner with a higher degree of freedom.

As described above, the game state can be changed variously only by changing the effective line without changing the winning probability or reel stop control in the lottery drawing, so that the storage data increases and the execution control steps increase. It is possible to change the progress of the game while suppressing the game, and to expect the player to be more interested in the game.
In addition, even in the same SBn game (n = 1 to 2), there are an SB1 game for starting the RT operation state and an SB2 game for releasing the RT operation state, so the game can be performed without changing the reel stop control or the like. A thrill and game fun can be given to the player, and the player's interest in the game can be increased.
In particular, in this embodiment, a part of the active line is changed based on the central horizontal line (middle, middle, middle) L1 common to each gaming state, and the RT operation state is changed depending on the position of the changed portion. An effective line serving as a starting point for starting and an effective line serving as a starting point for releasing the RT operation state are formed. Therefore, a slight change in the setting conditions can give a change to the progress of the game while suppressing an increase in stored data and an increase in the number of execution control steps. Furthermore, in addition to the award bonus on the common central horizontal line (middle, middle, middle) L1, it is possible to give the player a sense of expectation to move to RT and a thrill of whether to fall from RT, It can be expected that the player's interest in games will be raised.

  In the present embodiment, the BB combination is set, and when the BB combination is won in the combination lottery and the BB combination wins with the BB flag set, the BB game is played from the next game. However, it is also possible not to set the BB combination. In this case, the central horizontal effective line (medium / middle / middle) L1 having a common combination of symbols corresponding to any winning combination in the combination lottery by pull-in control When displayed above, the RT start / release symbol is always displayed on the active line (middle / middle / up) L2A or (middle / middle / bottom) L2B that is valid in SB1,2 game. It is possible to always give the player some sense of expectation and thrill, as well as the benefits due to winning, and it can be expected to increase the player's interest in the game.

  In addition, when any winning symbol is displayed on the central horizontal effective line (middle / middle / middle) L1, the RT start / release symbol is always the valid line (middle / middle / up) L2A (middle / middle).・ Bottom) When displayed on L2B, the symbol determination on the active line (middle / middle / up) L2A and (middle / middle / bottom) L2B is omitted, and RT start / release control processing is performed. You can also. Accordingly, it is possible to efficiently change the progress of the game while further suppressing the increase in the stored data and the increase in the number of execution control steps.

Returning to the description of the flowchart again, in step S422, 0 is input as the value of the parameter NSB, the SBn game is terminated, and this subroutine is terminated.
As described above, the SBn game is a hit game in which only one game in which the parameter NSB is initialized when one game is performed. Next, the winning / non-winning processing subroutine will be described in detail with reference to FIG.

<Description of winning and non-winning processing subroutine>
In the winning / non-winning processing subroutine, first, as a result of the winning symbol determination in step S402 or 412 in FIG. 11, it is determined whether or not any winning combination has been won (step S500).
If it is determined in this determination that the player has won any combination (YES), it is next determined whether or not the BB combination has won (step S502). If it is determined in this determination that the BB combination has won (YES), 1 is input to the value of NBB to set the BB gaming state (step S504). Then, the winning BB flag is turned off (step S506), and this subroutine is finished. By inputting 1 to the value of NBB, the BB game is played from the next game. For example, in the determination of step S42 in FIG. 6, it is determined that the BB game is in progress.

  If it is determined in step S502 that the BB combination has not won (NO), it is next determined whether or not the SBn combination has won (step S508). If it is determined in this determination that the SBn combination has won (YES), 1 or 2 is input to the NSB value (step S510). That is, when the SB 1A to 1C combination wins, 1 is input to the NSB value, and when the SB 2 combination wins, 2 is input to the NSB value. With this process, the SBn game is performed in the next game (see, for example, step S166 in FIG. 9). Then, the SB flag is turned off. If the BB flag is turned on, a flag carry-over process is performed (step S512), and this subroutine is terminated.

  If it is determined in step S508 that the SBn combination has not won (NO), it is next determined whether or not the re-game combination has won (step S514). If it is determined in this determination that the re-gamer has won (YES), 1 is input to the value of NRP (step S516). By this process, a re-game is performed in the next game (see step S22 in FIG. 5). Then, the re-game flag is turned off. If the BB flag is turned on, a flag carry-over process is performed (step S518), and this subroutine is terminated.

If it is determined in step S514 that the re-gamer has not won (NO), the general combination flag is turned off. If the BB flag is on, the flag carry-over process is performed. (Step S520), and this subroutine is completed.
Returning to the determination in step S500, if it is determined that there is no winning (NO), it is next determined whether or not the BB flag is on (step S522). In this determination, if it is determined that the BB flag is on (YES), carry-over processing of this BB flag is performed, and if other flags (general combination, replay combination) are on, The flag is turned off (step S524), and this subroutine is terminated.

  If it is determined in step S522 that the BB flag is not turned on (NO), the flag turned on (general combination, replay combination) is turned off (step S526), and this subroutine is executed. finish.

<Normal RT Process Subroutine Description>
Next, in the determination and flag-off process subroutine (see FIG. 9), FIG. 12 shows a detailed description of the normal RT gaming process subroutine (see step S170) that is performed when it is determined that there is a winning combination in step S168. This is done using a flowchart.
First, a winning symbol determination is performed with the central horizontal line (medium / medium / medium) L1 as an effective line (step S450), and a winning / non-winning processing subroutine is executed based on the winning symbol determination by the central horizontal effective line L1. Then, this subroutine is finished. It differs from the above-mentioned SB game processing subroutine in that the effective line used for winning symbol determination is different (the effective line that is effective only by SB is not used), but the contents of the winning / non-winning processing subroutine are as described above. Since it is the same as the case of the SB game processing subroutine, further explanation is omitted.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S162, S166, and S170 ends, and the winning determination and flag-off process subroutine shown in FIG. 9 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off processing subroutine in step S28 is terminated, payout processing is performed in step S30, and this main routine is terminated. Thereby, the control process for performing a game in which one process from the time the symbol fluctuates until it stops is completed.

<Description of production control subroutine>
Next, with reference to the flowchart shown in FIG. 14, an effect control subroutine mainly performed by the effect control means 540 of the sub control circuit 200 will be described in detail. In this effect control subroutine, based on the signal received from the main control circuit 100, in the game in which the RT is operating, when the general role and the SBn role are won in the role lottery at that time, the symbol corresponding to the selected general role is notified. The control process which performs the effect to perform is shown. Although not shown, the effect control means 540 also performs control processing for implementing other effects.

  In FIG. 14, it is first determined whether or not an RT information signal (see FIG. 6, step S48) has been received from the main control circuit 100 (step S800). If it is determined in this determination that the RT information signal has not been received (NO), this subroutine is terminated as it is. If it is determined in step S800 that the RT information signal has been received (YES), it is next determined whether or not a role lottery information signal (see FIG. 7, step S88) has been received from the main control circuit 100. (Step S802).

If it is determined that the combination lottery information signal has not been received (NO), this subroutine is terminated. If it is determined in step S802 that the combination lottery information signal has been received (YES), then whether or not the general combination and the SBn combination are won simultaneously in the combination lottery based on the received combination lottery information signal. Is determined (step S804).
If it is determined in this determination that the general combination and the SBn combination are not won simultaneously in the combination lottery (NO), this subroutine is terminated as it is. If it is determined in the step S804 that the general combination and the SBn combination are won at the same time in the combination lottery (YES), the predetermined image data is read from the RAM 210, transmitted to the image control means 510, and is selected. A control process for displaying on the display device 70 an image for notifying the player of the symbol corresponding to the general combination is performed.

  When a SB2 role is won in a game in which RT is active, the symbol corresponding to any winning combination (except for the BB winning) will be the central horizontal line (middle / middle / middle) due to pull-in control in the next SB2 game. When displayed on L1, the RT release symbol is always displayed on the active line (middle, middle, and lower) L2B that is valid only during the SB2 game, so the RT operating state is released. Therefore, when the general combination and the SBn combination are simultaneously won in the combination lottery during RT operation, if there is a notification of the symbol corresponding to the selected general combination, the player wins the general combination instead of the SBn combination. Since the reel stop operation can be performed as described above, the risk that the RT operation state is released can be avoided.

If this is shown by a specific example, for example, in the general lottery table at the time of RT operation shown in FIG. 16, the general role 2B (red 7, blue cherry, blue cherry) of symbol number 4 and the SB2 role of symbol number 14 (replay, blue cherry) (Cherry, Blue Cherry) is won at the same time, and the player performs a reel stop operation so that the player stops red 7 with the left reel by a notification effect, and the general role 2B is won, and the SB2 role is won. Can be avoided.
Therefore, since the RT operation state advantageous to the player can be continued for a long time by the notification effect, it can be expected that the player's interest in the game is increased.

Although not shown in the flowchart, in a normal game, when the general combination and the SB1 combination are won at the same time, it is also possible to perform an effect of notifying the symbol corresponding to the selected SB1 combination. In this case, because of the notification effect, the player can perform the reel stop operation so that the SB1 combination wins instead of the general combination, so that the possibility of performing the SB1 game in the next game is increased.
In the normal game, when the SB1 combination wins, in the next SB1 game, the symbol corresponding to any winning combination (excluding BB winning) is on the central horizontal line (middle / middle / middle) L1 by the pull-in control. Since the RT start symbol is always displayed on the active line (middle / middle / up) L2A that is valid only during the SB1 game, the RT can be started.

If this is shown by a specific example, for example, in the general lottery table when the BB is not operating shown in FIG. 17, the general combination 1A (red 7, red cherry, red cherry) of symbol number 1 and the SB1A role of symbol number 11 (red) (Blank, Red Cherry, Red Cherry) can be won at the same time by performing a reel stop operation so that the player stops the red blank with the left reel by a notification effect.
Therefore, since the possibility of starting an RT operation state advantageous to the player is increased by the notification effect, it can be expected that the player's interest in the game is increased.
