Description

  The present invention relates to a slot machine in which a player inserts a game medium, rotates and stops a reel on which a symbol is displayed, and determines a game result by a combination of symbols displayed on the effective line. The present invention relates to a slot machine having a function capable of changing the function.

  A slot machine, in which a player inserts a game medium, rotates a reel on which a symbol is displayed, stops it, and determines a game result by a combination of symbols displayed on an active line, is widely used as one of the gaming machines. It has been. In this slot machine, a lottery is usually performed by the control means, and when a combination of symbols corresponding to the winning combination in the role lottery is displayed on the active line and a prize is won, it corresponds to the winning prize for the player. Benefits are provided.

Some of these slot machines can change the effective line. For example, a slot machine that changes the effective line and displays information related to the effective line has been proposed (see, for example, Patent Document 1).
JP 2007-050307 A

  In the slot machine described in Patent Document 1, the progress of the game can be changed by changing the effective line. However, in order to realize this, when a reel stop signal corresponding to each changed active line, that is, when a reel stop signal based on a player's stop operation is received, a predetermined reel rotation amount (slip amount) ), It is necessary to perform control to stop the symbols corresponding to the winning combination on each active line. For this reason, it is necessary to store a stop symbol pattern for stop control corresponding to each effective line, and the accompanying control processing is also required, so an increase in stored data and an increase in the number of execution control steps are inevitable. . For this reason, in the main control circuit with limited storage capacity and processing speed, there is a possibility that a sufficient change in the gaming situation cannot be realized.

  Accordingly, the object of the present invention is to solve the above-mentioned problems, and to change the state of profit provision to the player or to change the progress of the game while suppressing an increase in stored data and an increase in the number of execution control steps. It is an object of the present invention to provide a slot machine that can increase a player's interest in games.

  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 lottery drawing means for performing a lottery for determining at least one combination or disparity from among a plurality of combinations by lottery processing, and a plurality of symbols are displayed. After rotating a plurality of reels, in accordance with the result of the winning combination lottery, a reel control means for performing stop control of the rotated reel, and a flag is set when any winning combination is won in the winning lottery, In a state where the flag is set, when it is determined that a combination of symbols corresponding to the selected winning combination is displayed on the active line and a winning combination is made, a winning process control means for performing a winning process corresponding to the winning combination The same reel stop control is carried out, but there are a plurality of game states with different set effective lines, and in the plurality of game states, the predetermined reel lottery result by the same reel stop control is obtained. Even if the display styles of the corresponding symbols are the same, it is conceivable that the state of providing benefits to the player in each gaming state differs due to the difference in the set effective lines.

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. Further, when two or more winning combinations are won at the same time, 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 the “plurality of gaming states” include a case where one gaming state is a normal game and the other gaming state is an SB game, and a plurality of gaming states include a plurality of SBs. A case where a game is set is also conceivable. However, the present invention is not limited to this, and any other game modes including other winning games can be combined as long as the set active lines have different game states.

As an aspect in which the active lines are different in a plurality of gaming states, for example, there may be a case where the set effective lines are different in a plurality of gaming states, or a case where some of the active lines are common. In addition, regarding the number of activated lines set, the same number of activated lines may be set in each gaming state, or a different number of activated lines may be set.
In addition, the active line does not necessarily have to be aligned in a straight line in the stop symbols of the right, middle, and left reels. For example, three symbols can be visually recognized vertically on each reel in the display window (that is, a total of nine symbols are displayed). In the case of being visually recognizable, the effective line in each reel can take an arbitrary position of upper, middle, and lower, and a total of 27 effective lines can be assumed.

  In addition, as a mode of changing the state of providing benefits to the player, for example, as will be described later, it is realized by changing the progress of the game, which may be realized by changing the number of paid out game media. It is also possible to realize this by indirectly changing the winning status of the winning combination by changing the contents of the production.

  In the present embodiment, even if the same symbol display mode is obtained by the same reel stop control using the same reel control data, the benefit supply state to the player is changed by changing the effective line. Therefore, it is possible to change the state of providing benefits to the player while suppressing an increase in stored data and an increase in the number of execution control steps. Accordingly, it is possible to provide an attractive slot machine that can increase the player's interest in the game by using a control device having a limited capacity and performance.

  In the slot machine according to the present invention, it is further conceivable that the set betting number of the game media is different in the plurality of game states.

  In this embodiment, the change of the active line is realized by changing the betting number, so that the progress of the game can be easily changed.

  In the slot machine according to the present invention, a plurality of the effective lines are set in at least one of the plurality of gaming states, and the reel is based on a predetermined effective line among the plurality of effective lines. If the symbol determination at the time of stop is performed, the reel symbol arrangement that can determine the state of profit provision to the player based on all the set effective lines without performing the symbol determination based on the other effective lines. It is thought that it has been made.

  In this embodiment, in a gaming state in which a plurality of active lines are set, if the symbol determination at the time of reel stop is performed based on a predetermined effective line, the symbol determination based on the other effective lines is not necessarily performed. The reel design is such that the content of the benefit provision on the active line is uniquely determined. Therefore, since it is possible to determine the state of benefit provision to the player regarding all active lines without performing symbol determination regarding all active lines, it is possible to effectively suppress an increase in stored data and an increase in the number of execution control steps. Can do. The predetermined effective line may be one effective line or a plurality of effective lines.

  In the slot machine according to the present invention, it is further conceivable that the common effective line is set in the plurality of gaming states, and the common effective line is the predetermined effective line.

According to the present embodiment, since a common effective line is set in a plurality of gaming states, and further, the effective line is set to the predetermined effective line, the symbol determination based on the common effective line It is possible to determine the state of providing benefits to the player in an arbitrary gaming state among a plurality of gaming states simply by performing the above. Thereby, it is possible to change the profit providing state to the player for each gaming state while suppressing an increase in stored data and an increase in the number of execution control steps.
In addition, in each gaming state, it is possible to variously change the state of profit provision to the player by using further active lines other than the common active line.

  Further, in the slot machine according to the present invention, it is conceivable that the difference in the state of providing benefits to the player among the plurality of gaming states is caused by the difference in the number of game media to be paid out based on winning combinations.

  According to the present embodiment, by changing the active line, the number of game media to be paid out in the winning combination of the winning combination is changed to change the state of profit provision to the player. Regarding the payout of the game medium, the player can directly realize the profit providing state, and the player's interest in the game can be easily increased.

  In the slot machine according to the present invention, it is further conceivable that a difference in the state of providing benefits to the player between the plurality of gaming states is caused by whether or not the game mode can be changed.

Here, examples of the “game mode” include a normal game mode, a win game mode (BB game mode), a re-game selection high mode, and the like. Furthermore, when a plurality of types of BB games and a plurality of types of re-game selection high states are set, the respective BB games and re-game selection high states can be set to different game modes.
In this embodiment, when a game mode transition symbol that triggers a game mode transition when set on the active line is set, even if the display mode of the symbol of the stopped reel is the same, the active line is not displayed. By changing, it is possible to change whether or not the game mode can be changed.

  Therefore, in this embodiment, since the difference in the state of profit provision to the player is caused by whether or not the game mode can be changed, it is possible to give the player a thrill and a fun of the game, and the player's interest in the game is increased. Can be increased.

  According to the above-described invention, even when the same symbol display mode is obtained by the same reel stop control using the same reel control data, the benefit supply state to the player can be improved by changing the effective line. Since it can be changed, it is possible to change the state of provision of benefits to the player while suppressing an increase in stored data and an increase in the number of execution control steps, and thereby a control device with limited capacity and performance. Can be used to provide an attractive slot machine that shows high interest to the player.

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.

  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 S518 in FIG. 13, 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 S52. Here, an example of the general lottery table during BB operation is shown in FIG.

In the BB operation lottery table, three general combinations of symbol numbers 1 to 3 and a deviation of symbol number 4 are set.
For the general combination 1 with symbol number 1, the winning probability in the combination lottery is 1/20, and when a red cherry symbol is displayed on the active line of the left reel, Even if the symbol is displayed, it is set to win.
For the general combination 2 with symbol number 2, if the winning probability in the combination lottery is 1/20, and the blue cherry symbol is displayed on the effective line of the left reel, Even if the symbol is displayed, it is set to win.
The general combination 3 with symbol number 3 is set to win when the winning symbol in the combination lottery is 1 / 1.12 and a bell symbol is displayed on the effective line of the left, middle and right reels. Has been. Therefore, during the BB game, the possibility of winning the general combination 3 in the combination lottery is very high.
Further, the probability of the symbol number 10 coming off is about 1/140, 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 BB game is finished, 1 is input to the value of NRT (FIG. 10). (See step S314). Further, in the RT operating state, when the requirement for canceling the RT operating state is satisfied, specifically, when the BB game starts (see step S507 in FIG. 13), 0 is input to the value of NRT. It has become. Although not shown in the flowchart, when a predetermined RT start symbol is displayed on the active line (see FIG. 22), the RT operation state is started and the predetermined RT release symbol is displayed on the active line. When the game is played (see FIG. 23), the RT operation state can be set to end, or the RT operation state is set to be released when the number of games in the RT operation state reaches a predetermined number. You can also

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 out (step S46). Here, an example of the general lottery table during RT operation is shown in FIG.
In the RT lottery table at the time of RT operation, three general roles with symbol numbers 1 to 3, a replaying role with symbol number 4, two SBn roles with symbol numbers 5 to 6 (n = 1 to 2), and symbol numbers 7 BB combination and symbol number 8 are set off. In addition, compared with the BB non-operating general lottery table (see FIG. 16) used in the normal gaming state, the set role and the symbol are the same, but with respect to the winning probability of the re-game player of symbol number 4, 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.

  About the general combination 1-2 of the symbol numbers 1-2, both the above-mentioned general lottery table | surface (refer FIG. 14) at the time of BB operation | movement, and a symbol and winning probability are set identically. However, for the general combination 3 of the symbol number 3, the symbol is the same, but the winning probability is 1/5, which is compared with the general lottery table (1 / 1.12) at the time of BB operation shown in FIG. Is set low. It should be noted that all symbols of symbol numbers 1 to 3 are set to be the same as the BB non-operating general lottery table (see FIG. 16), which will be described later, and symbols and winning probabilities.

The re-playing combination with symbol number 4 is set to win when the winning probability in the combination lottery is ½ and the replay symbol is displayed on the effective line of the left, middle and right reels. Yes. It is set higher than the winning probability (1 / 7.3) of the re-gamer in the general game table (see FIG. 16) when the BB is not operated, which will be described later.
In addition, symbols SB 1 to 2 with symbol numbers 5 to 6 each have a winning probability of 1/500 in the symbol lottery, and a red cherry or blue cherry symbol is displayed on the effective line of the left reel. When a black blank symbol is displayed on the active line, a winning is set.

The BB combination with symbol number 7 is set to win if the winning probability in the combination lottery process is 1/300 and the red 7 symbol is displayed on the active line of the left, middle and right reels. ing. The winning symbols and winning probabilities of the SBn combination and the BB combination are the same as those in the general lottery table (see FIG. 16) when the BB is not operating, which will be described later. Therefore, as is clear from a comparison between FIG. 15 and FIG. 16, when RT is activated, the winning probability in the re-game combination lottery is set higher than in the normal game state. The winning combinations are set exactly the same. The probability of losing (about 1 / 5.19) is set 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 5 to 6 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. 15).

Returning to the description of the flowchart of FIG. 6, the general lottery table for RT operation is read in step S46, and then the process proceeds to step S52.
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, and includes three general roles of symbol numbers 1 to 3, a re-game role of symbol number 4, and two of symbol numbers 5 to 6 The SBn combination (n = 1 to 2), the BB combination of the symbol number 7 and the deviation of the symbol number 8 are set. Compared to the RT lottery table at the time of RT operation (see FIG. 15), the winning probability of the re-gamer with symbol number 4 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. 15). Also, the probability of symbol number 8 losing is about 1 / 1.80, and the winning probability of the re-gamer is set lower than the RT lottery table at the time of RT operation (see FIG. 16), The probability of loss is high.

In the normal game, when the SBn role of symbols 5 to 6 wins and wins, the SB1 game or the 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 BB non-operating general lottery table (see FIG. 16). 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 any lottery table, when the general combination 1 wins, the number of payouts of game media is 5, when the general combination 2 wins, the payout number of game media is 1 and the general combination 3 wins. In this case, the payout number of game media is five. If any other combination wins, no game media will be paid out. Further, in the present embodiment, the general numbers 1 to 3 are set with numbers so that the winning combinations may be won at the same time (details will be described later with reference to FIG. 24). A 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 = 1 to 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), and this subroutine is terminated.

<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 (medium / middle / medium) L1 is an effective line, but in the SB1 game, in addition to the central horizontal line (middle / middle / medium) L1,・ Up / Middle L2A and Line (Up / Middle / Middle) L2B are also effective lines. In SB2 games, in addition to the central horizontal line (Middle / Middle / Middle) L1, line (Low / Middle / Middle) L3 It becomes an effective line.
As will be described later, for example, in the SB1 game, when the general winnings 1 to 3 are simultaneously won in the role lottery, the drawing (bell bell bell) corresponding to the general winning role 3 is drawn in the central horizontal line (middle (Middle / Middle) When displayed on L1, the symbol (red cherry / any / any) corresponding to the general role 1 is always displayed on the line (Up / Up / Middle) L2A, and the line L2B (Up / Middle) The reel symbol arrangement is such that the symbol (red cherry, any, any) corresponding to the general combination 1 is displayed on the middle / medium).
Similarly, in the SB2 game, when the general lots 1 to 3 are simultaneously elected in the role lottery, the drawing (bell bell bell) corresponding to the general role 3 is the central horizontal line (middle / middle / middle) by the pull-in control. When displayed on L1, the reel symbol arrangement is such that the symbol (blue cherry, any, any) corresponding to the general combination 2 is always displayed on the line (lower, middle, middle) L3. . A more detailed description will be described later with reference to FIGS.

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.

<Description of Flag Off, RT Setting 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). In this determination, if it is determined that the BB game end condition has been achieved (YES), 0 is input to the NBB value to release the BB game state (step S312), and then the NRT value. Then, a control process for inputting 1 to the terminal is performed (step S314), and this subroutine is terminated. By the control process in step S314, the RT operation state is started from the next game (see step S44 in FIG. 6).
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, SB1 is being played, then the central horizontal line (middle / middle / middle) L1, line (up / up / middle) ) With L2A and line (up / middle / middle) L2B as effective lines, a winning symbol determination is performed (step S402), and the process proceeds to step S406.

If it is determined in step S400 that the NSB value is not 1 (NO), it is determined that the NSB value is 2, that is, SB2 is being played, and then the central horizontal line (middle With the middle (middle) L1 and the line (lower, middle, middle) L3 as effective lines, a winning symbol determination is performed (step S404), and the process proceeds to step S406.
In step S406, a winning / non-winning processing subroutine (step S406) for performing a predetermined control process is performed according to the case where each winning combination has won or not, and the process proceeds to step S408. Details of the winning / non-winning processing subroutine will be described later with reference to FIG.
In step S408, 0 is input to the value of the parameter NSB, the SBn game is terminated (step S408), 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.

<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 using the central horizontal line (medium / medium / medium) L1 as an effective line (step S450), and based on the winning symbol determination by the central horizontal effective line L1, a winning / non-winning processing subroutine ( Step S452) is performed, and this subroutine is terminated. It differs from the above-mentioned SB gaming 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 control contents of the winning / non-winning processing subroutine are as described above. This is the same as the SB game processing subroutine. 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, based on the winning symbol determination in step S402 or S404 in FIG. 11 or based on the winning symbol determination in step S450 in FIG. (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). 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.
Then, the winning BB flag is turned off (step S506), 0 is input to the value of NRT (step S507), and this subroutine is terminated. The RT operation state is canceled by initializing by inputting 0 as the value of NRT.

  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). In other words, when the SB1 combination wins, 1 is input to the NSB value, and when the SB2 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). In this determination, if it is determined that the re-game player has not won (NO), it is determined that the general player has won, and a control process for calculating the number of game media to be paid out according to the set active line (Step 515).

<Explanation of the number of payouts according to the effective line>
Here, with reference to FIG. 17 to FIG. 20 and FIG. 24, an explanation will be given regarding the calculation of the number of payouts of game media according to the active line, taking as an example the case where the general winnings 1 to 3 are won simultaneously in the winning lottery.
In the present embodiment, an explanation will be given by taking as an example a normal game or a case of SB1, SB2 game when a combination lottery is performed using a general lottery table when BB is not activated (see FIG. 16). In this case, as shown in FIG. 24, when the general winning combinations 1 to 3 have the same number of winning areas (simultaneous winning areas), and random numbers in the simultaneous winning areas are extracted in the winning lottery, Roles 1 to 3 are elected simultaneously. In addition, the winning general combination 1 wins when the red cherry, any, and any symbols are displayed on the set active line, and the winning general combination 2 wins the set When the blue cherry, any, and any symbols are displayed on the active line, the winning general combination 3 wins when the bell, bell, and bell symbols are displayed on the set active line. It is. The reel symbol arrangement in this embodiment is as shown in FIG.

<< For normal games >>
First, let us consider a case where the general winnings 1 to 3 are simultaneously won by the winning lottery during the normal game. In a normal game, as shown in FIG. 18, the central horizontal line (middle / middle / middle) L1 is set as an effective line (the colored portion indicates the valid line). Middle / Medium) If the player performs a reel stop operation at the timing when there is a symbol bell corresponding to the general combination 3 within the range of 5 frames from L1, the bell symbol is preferentially displayed on the display window. Pull-in control is performed to stop at the middle position. Note that the above-mentioned “priority” means that the pull-in control is performed preferentially when there is a possibility that the general combination 3 will win, for example, in the left reel stop control, it has already stopped. In the middle reel or right reel, if the bell symbol is not stopped at the middle position of the display window, there is no possibility that the general combination 3 will win, so the red cherry symbol corresponding to the general combination 1 Pull-in control is performed preferentially so that the blue cherry symbol corresponding to the combination 2 stops at the middle position of the display window.
With the above pull-in control, as shown in FIG. 18, when the bell-bell-bell symbol is displayed on the central horizontal line (middle / middle / middle) L1, it is assumed that the general combination 3 has won a prize. Judgment is made to calculate 5 as the payout number of game media.

<< In case of SB1 game >>
Next, consider a case where the general roles 1 to 3 are simultaneously won in the role lottery during the SB1 game. In the SB1 game, as shown in FIG. 19, the central horizontal line (middle / middle / middle) L1, the line (up / middle / middle) L2A, and the line (up / middle / middle) L2B are set as effective lines. ing. If the player performs a reel stop operation at the timing when the symbol bell corresponding to the general role 3 exists in the range within 5 frames from the central horizontal line (medium / medium / medium) L1, priority is given. The pull-in control is performed so that the bell symbol stops at the middle position of the display window. Here, “preferentially” is used in the same meaning as described above.
When the bell-bell-bell symbol is displayed on the central horizontal line (middle / middle / middle) L1, as shown in FIG. 5 is calculated as the number of game media to be paid out.

Further, in this embodiment, when a bell bell bell symbol is displayed on the central horizontal line (middle / middle / middle) L1, as shown in FIG. -Middle) Since the symbol of red cherry, any, and any is displayed on L21, it is determined that the general combination 1 has won, and 5 is added as the number of game media to be paid out.
Furthermore, when the bell-bell-bell symbol is displayed on the center horizontal line (middle, middle, middle) L1, as shown in FIG. 19 (b3), on the line (upper, middle, middle) L2B In addition, since the symbols of red cherry, any, and any are displayed, it is determined that the general combination 1 has won, and 5 is further added as the number of game media to be paid out. As a result, in the SB1 game, the total payout number of game media is calculated as 5 + 5 + 5 = 15.

As described above, even if the display pattern of the stop reel is exactly the same as in the case of a normal game, the effective line is changed (in this embodiment, additional effective lines are added), so that the game medium is changed. The number of payouts can be changed.
In the embodiment shown in FIGS. 18 and 19, the case where the symbols of frame numbers 13, 14, and 15 are displayed on the display window on the left reel is shown. However, as shown in FIG. Even when the bell symbol is displayed at the position of the display window, when the bell symbol is displayed at the middle position of the display window, the red cherry symbol is always displayed at the upper position. It has become. In other words, whenever a bell, bell, or bell symbol is displayed on the center horizontal line (middle, middle, middle) L1, the line (upper, middle, middle) L2A and the line (upper, middle, middle) The red cherry, any, and any symbols are displayed on L2B.

  With the reel symbol arrangement as described above, in the SB1 game, the general roles 1 to 3 were won in the role lottery, and the bell, bell, bell were displayed on the central horizontal line (middle, middle, middle) L1 and won. In this case, it is possible to determine that the general combination 1 has won a prize in both active lines without performing symbol determination on the line (up, middle, and middle) L2A and the line (up, middle, and middle) L2B. Based on this determination, a total payout number of 15 can be determined.

<< In case of SB2 game >>
Next, let us consider a case where the general roles 1 to 3 are simultaneously won in the role lottery during the SB2 game. In the SB2 game, as shown in FIG. 20, the central horizontal line (middle / middle / middle) L1 and the line (lower / middle / middle) L3 are set as effective lines. If the player performs a reel stop operation at the timing when the symbol bell corresponding to the general role 3 exists in the range within 5 frames from the central horizontal line (medium / medium / medium) L1, priority is given. The pull-in control is performed so that the bell symbol stops at the middle position of the display window. Here, “preferentially” is used in the same meaning as described above.
When the bell / bell / bell symbol is displayed on the central horizontal line (medium / medium / medium) L1, as shown in FIG. 5 is calculated as the number of game media to be paid out.

  Furthermore, when the bell-bell-bell symbol is displayed on the central horizontal line (middle / middle / middle) L1, as shown in FIG. 20 (c2), on the line (lower / middle / middle) L3 In addition, since the symbols of blue cherry, any, and any are displayed, it is determined that the general combination 2 has won, and one is added as the number of game media to be paid out. Thereby, in the SB2 game, the total payout number of game media is calculated as 5 + 1 + 1 = 6.

  As described above, even when the display pattern of the stop reel is exactly the same as in the case of a normal game or SB1 game, the payout number of game media can be changed by changing the effective line. In other words, compared to the normal game (five payouts), in the SB1 game, a very large profit (15 payouts) can be given to the player, and in the SB2 game, a slightly large profit (to the player) 6 sheets can be paid out).

  18 and 20, the symbols of frame numbers 13, 14, and 15 are displayed on the display window on the left reel. However, as shown in FIG. Even if the bell symbol is displayed in the middle of the display window, the blue cherry symbol is displayed in the lower position of the display window. In other words, when the bell, bell, bell symbol is displayed on the center horizontal line (middle, middle, middle) L1, the blue cherry, any, and any are always displayed on the line (lower, middle, middle) 3. A symbol is displayed.

  With the above reel symbol arrangement, even in the SB2 game, general roles 1 to 3 were won in the role lottery, and the bell, bell, bell were displayed on the central horizontal line (middle, middle, middle) L1 and won. In this case, it is possible to determine that the general combination 2 has won a prize in the line (lower / middle / middle) L3 without performing the symbol determination on the line (lower / middle / middle) L3. 6 sheets can be defined.

As described above, even if the same symbol display mode is obtained by the same reel stop control using the same reel control data, the benefit line is provided to the player by changing the effective line (this implementation) In the example, the game media payout number) can be changed, so that it is possible to change the state of profit provision to the player while suppressing an increase in stored data and an increase in the number of execution control steps. By using a controller with limited capacity and performance, it is possible to provide an attractive slot machine that shows high interest to the player.
In addition, by appropriately setting the symbol arrangement of the reels and the position of the effective line, it is possible to determine the state of profit provision to the player regarding all the effective lines without performing the symbol determination of the stopped reel regarding all the effective lines. Therefore, an increase in stored data and an increase in the number of execution control steps can be effectively suppressed.

In this embodiment, a common effective line (center horizontal line (middle / middle / middle) L1) is set in a plurality of game states (normal game, SB1 game, and SB2 game). If the symbol determination based on the active line is performed, among the plurality of gaming states (normal game, SB1 game, and SB2 game) without performing symbol determination regarding the other effective lines (effective lines L2A, L2B, L3) It is possible to determine a state of providing a profit to the player in any game state (in this embodiment, the number of game media to be paid out). Thereby, an increase in stored data and an increase in the number of execution control steps can be suppressed. In addition, in the SB1 game and the SB2 game, it is possible to variously change the profit provision state to the player by using additional effective lines (effective lines L2A, L2B, and L3) other than the common effective line.
As described above, regarding the payout of the game medium, the player can directly realize the profit providing state, and in this embodiment, the player's interest in the game can be easily increased.

<Explanation of flowchart (continued)>
Returning to the description of the flowchart again, following step S515, the general combination flag is turned off. If the BB flag is turned on, a flag carry-over process is performed (step S516), and this subroutine is executed. Exit.

  If it is determined in step S514 that the re-game player has won (YES), 1 is input to the value of NRP (step S518). By this process, a re-game is performed in the next game (see step S22 in FIG. 5).

<Explanation regarding the possibility of transition to other game modes according to the active line>
Here, with reference to FIGS. 17 and 21 to 23, the case where the re-game player wins will be described as an example, and whether or not it is possible to shift to another game mode according to the active line will be described. In this embodiment, as an example of whether or not to shift to another game mode, the case where the RT operation state is started from the normal game and the case where the RT operation state is released and the game is shifted to the normal game are taken as examples. explain.

<< For normal games >>
First, consider a case where a re-game is won by a role lottery during a normal game. In the normal game, as shown in FIG. 21, the center horizontal line (middle / middle / middle) L1 is set as an effective line, so if within five frames from the middle horizontal line (middle / middle / middle) L1 When the player performs a reel stop operation at the timing when the replay symbol corresponding to the re-gamer is present in the range, the pull-in control is performed so that the replay symbol stops at the position in the display window. .
FIG. 21 shows a case where a replay / replay / replay symbol is displayed on the central horizontal line (middle / middle / middle) L1 by the pull-in control as described above, and replay is performed in the next game. .

<< In case of SB1 game >>
Next, consider a case where a re-game is won in the role lottery during the SB1 game. In the SB1 game, as shown in FIG. 22, the central horizontal line (middle / middle / middle) L1, the line (up / middle / middle) L2A, and the line (up / middle / middle) L2B are set as effective lines. ing.
FIG. 22 shows a case where a replay / replay / replay symbol is displayed on the central horizontal line (middle / middle / middle) L1 by the pull-in control as described above, and replay is performed in the next game. .

Furthermore, in this embodiment, when the replay / replay / replay symbol is displayed on the center horizontal line (middle / middle / middle) L1, as shown in FIG.・ Middle) Blue cherry, any, and any symbols are displayed on L2A. In this embodiment, the blue cherry, any, and any are set as the RT operation state start symbol, and when this blue cherry, any, and any symbol is displayed on the active line, the RT operation state is started from the next game. Is started (however, not shown in the flowcharts of FIGS. 5 to 13).
Furthermore, when a replay / replay / replay symbol is displayed on the center horizontal line (middle / middle / middle) L1, as shown in FIG. 22 (b3), on the line (up / middle / middle) L2B Since the symbols of the blue cherry, any, and any that are the RT operation start symbols are displayed, the RT operation state is similarly started from the next game.

As described above, even if the display pattern of the stop reel is exactly the same as in the case of a normal game, the transition of the game mode is made by changing the effective line (in this embodiment, additional effective lines are added). Whether or not (RT operation state start possible) can be changed.
As shown in FIG. 17, since the blue cherry symbol is always placed above the replay symbol on the left reel, the re-playing role is played in the SB1 game using the general lottery table when the BB is not activated. When winning, the RT operation state is always started.

<< In case of SB2 game >>
Next, consider a case where a re-game is won in the role lottery during the SB2 game. In the SB2 game, as shown in FIG. 23, the central horizontal line (middle / middle / middle) L1 and the line (lower / middle / middle) L3 are set as effective lines.
FIG. 21 shows a case where a replay / replay / replay symbol is displayed on the central horizontal line (middle / middle / middle) L1 by the pull-in control as described above, and replay is performed in the next game. .

  Further, when the replay / replay / replay symbol is displayed on the central horizontal line (middle / middle / middle) L1, in this embodiment, as shown in FIG. 23 (c2), the line (lower / middle / middle) is displayed.・ Middle) Red cherry, any, and any symbols are displayed on L3. In this embodiment, the red cherry, any, and any are set as the RT activated release symbols. If the red cherry, any, and any symbols are displayed on the active line, the RT is activated from the next game. The state is released (but not shown in the flowcharts of FIGS. 5 to 13).

As described above, even if the display pattern of the stop reel is exactly the same as in the case of a normal game or SB1 game, whether or not the game mode can be changed (the RT operation state can be canceled) by changing the effective line. Can be changed.
Therefore, since the difference in the state of profit provision to the player occurs depending on whether or not the game mode can be changed, it is possible to give the player a thrill and a fun of the game, and it can be expected to increase the player's interest in the game. .
As shown in FIG. 17, in the left reel, there are a portion where the red cherry symbol is placed and a portion where the red cherry symbol is not placed at a position below the replay symbol. When the re-game player wins, there are cases where the RT operation state ends and cases where it does not end.

<Explanation of flowchart (continued)>
Returning to the description of the flowchart again, following step S518, the replay flag is turned off. If the BB flag is turned on, a flag carryover process is performed (step S520), and this subroutine is executed. finish.

    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.

<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 control processing in sub-control circuit)
Although not described in the above flowchart, an information signal (for example, whether the game is a normal game or an SB1 game) from the main control circuit 100 to the sub control circuit 200 for each game. Has been sent. Based on this received information signal, the sub-control circuit 200 performs a control process for notifying the player of information related to the active line according to the gaming state at that time. For example, a control process for displaying information on the active line on the display device 70 is performed. By this control process, the player can perform the reel stop operation while recognizing the effective line according to the game state, so that the game can be fully enjoyed.
