Description

  The present invention relates to a slot machine in which a player inserts a game medium, rotates a reel on which a symbol is displayed, stops the game, and determines a game result by a combination of symbols at the time of stop, and in particular, does not insert a game medium. The present invention relates to a slot machine having a function capable of replaying.

  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 at the time of the stop is widely used as one of the gaming machines. In this slot machine, a winning combination is set as one of the winning combinations, a winning flag is set when winning a winning combination in the winning lottery, and the winning combination does not win in an internal state where the winning flag is set. In some cases, the internal middle state is carried over until winning, and when the winning combination is won in the internal middle state, the game has a function of performing a winning game that proceeds advantageously for the player. In addition, there is a function of setting a re-playing game as one of the roles, and performing a re-game in which the next game is performed without inserting a game medium when the re-playing service is won and won by a role lottery. Further, among the slot machines that perform this re-game, there are those that perform a game in the re-game selection high state in which the probability that a re-game player is won in the role lottery is set high.

Among the slot machines that can play a game in such a replay selection high state, a game is performed in the replay selection high state in the internal middle state, and a plurality of replay selection high states are set. Slot machines have been proposed. (For example, refer to Patent Document 1.)
JP 2005-218541 A

  In the slot machine proposed in Patent Document 1, a control process for changing from the first regame selection high state to the second regame selection high state is performed in the internal middle state. However, the purpose of performing such control processing is to set the second re-game selection high state for the zero-player that does not pay out the game media even if winning a prize, To be able to release continuously. Therefore, there are few factors that the player feels attractive about the game itself in the re-game selection high state, and if the winning combination is not stocked, the player's interest in the overall game including the game in the re-game selection high state May fall.

  Therefore, the object of the present invention is to solve the above-mentioned problems and to give the player a sense of tension and to give the player a sense of expectation that the game will proceed in an advantageous manner in the progress of the game performed in the re-game selection high state. An object of the present invention is to provide a slot machine capable of increasing and maintaining the interest of a player in games.

  In order to achieve the above object, as a slot machine according to the present invention, a game medium is inserted, a plurality of reels on which a plurality of symbols are displayed are rotated and stopped, and the game medium is determined according to the stop symbol. A slot machine capable of performing a game in which the step of paying out is performed once, and a role lottery means for performing a role lottery for determining one role by lottery from a combination including a winning combination and a re-game Reel control means for performing stop control of the reel corresponding to the reel stop signal among the plurality of rotated reels when the reel stop signal transmitted based on the stop operation of the player is received; A winning flag is set when the winning combination is won by lottery, and it is determined that the symbol corresponding to the winning combination does not stop and wins in the internal state where the winning flag is set. When the symbol corresponding to the winning combination stops and wins, the winning flag control means for controlling the internal state to carry over to the next game, and when the re-game player is won in the winning lottery Re-game control means for executing a re-game in which the next game is performed without inserting the game medium when it is determined that the symbol corresponding to the re-game player has stopped and won based on the result of the stop control; Replay selection high state control means for playing a game in a replay selection high state in which the probability that the replay player wins in the combination lottery is set to a higher value than a normal game when the predetermined requirement is satisfied, And when the predetermined combination wins in the first replay selection high state that starts when the replay selection high state satisfies a predetermined start requirement, and the first replay selection high state, First replay selection high status And a second re-game selection high state starting from the next game and an internal / medium re-game selection high state performed in the game of the internal / intermediate state are included. It is conceivable that a combination and the predetermined combination that is a requirement for starting the second replay selection high state may be won simultaneously.

  Here, the “game medium” is a medium inserted into the slot machine for playing a game, and for example, a coin, a medal, a chip, or the like can be considered. 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, or storing it in a storage medium of the slot machine. This includes using a predetermined number of game media credited in advance.

  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 “combination” includes at least a “winning role” for performing a “winning game” that advances the game in an advantageous manner for the player, a general role for paying out a predetermined number of game media when winning, and a game A “re-game player” for “re-game” that can re-execute the game without inserting a medium is included.

  “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 a big bonus combination (hereinafter referred to as BB combination), a regular bonus combination (hereinafter referred to as RB combination), and a single bonus combination (hereinafter referred to as SB combination).

  The RB combination is a combination that shifts to an RB game that is one of the winning games. In this RB game, a game in which a predetermined combination is won with a high probability can be performed a predetermined number of times under a certain condition. In addition, the BB role is a role for shifting to a BB game that is one of the winning games. This BB game can be used for general games and can be transferred to RB games under certain conditions during the general games. This is a game in which a general game and an RB game can be repeated until a predetermined number of game media payouts is reached. The SB combination is a transfer to SB game, which is one of the winning games. In this SB game, a game in which a predetermined winning combination is won with high probability in a game state where the specified number is one. It is a game that can be done. In addition, various other winning combinations and winning games can be set as long as the winning game performed by winning the winning combination proceeds in a manner advantageous to the player.

  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. In addition, in the general combination, it is possible to set “one combination” in which one game medium is paid out when winning.

  “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. Further, when the re-gamer wins and wins, the re-game can be performed with the same specified number as the re-gamer won, or can be re-played with a different specified number. An arbitrary number can be used as the specified number. It is also possible to set a plurality of types of re-game players.

  In the “lottery” for determining one combination, for example, it is desirable to generate a random number and determine 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.

  “Corresponding symbols 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 setting for stopping a predetermined symbol on all reels is included, and a setting for stopping a predetermined symbol on some reels is also included. Further, the predetermined symbol can be set to the same symbol for all the reels, or a different symbol can be set for each reel.

  “The corresponding symbol does not stop” means that the requirement for corresponding to the above “corresponding symbol stops” is not satisfied. Therefore, for example, even when a predetermined symbol does not stop on some of the reels that are required, it does not “stop”. Of course, even when a predetermined symbol does not stop on all the reels that are required, 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.

  Regarding the “predetermined start requirement” for starting the first re-game selection high state, as described later, it is also possible to set the start requirement that a specific game state such as a winning game has ended. . In addition, for example, it is possible to make it a start requirement to have consumed a predetermined number of games, and to start winning a predetermined role and winning a symbol according to that role And various other events can be set as starting requirements.

  Regarding the “predetermined combination” that is the requirement for starting the second replay selection high state, any combination including a general combination and a replay combination can be set, and a plurality of combinations can be set as will be described later. Can also be set.

  In this embodiment, in the winning combination lottery, a winning combination and a predetermined combination that is a start requirement of the second replay selection high state may be won at the same time. Therefore, when a predetermined winning combination wins, There is a possibility that. Therefore, when a predetermined winning combination is won in the first replay selection high state, it is difficult to determine whether to shift to the second replay selection high state or to the internal replay selection high state. With respect to the progress of the game, it is possible to give the player a sense of tension and to give the player a sense of expectation that the player will proceed to the game, so that the player's interest in the game can be expected to be maintained and maintained.

  The slot machine according to the present invention further includes effect control means capable of displaying a predetermined effect image, and a game executed in the second replay selection high state and a game executed in the internal medium replay selection high state In this case, the same effect image may be displayed.

  Here, the “effect control means” performs control to display a predetermined effect image on the display device using the image control means. Specifically, the image control means reads predetermined image data stored in the storage area of the control circuit and transmits it to the display drive circuit, and the display drive circuit displays an image based on the transmitted image data on the display device. To display. Further, the effect control means can display the effect image accompanied by the sound by using the sound control means.

  In the present embodiment, since the same effect image may be displayed in the game played in the second regame selection high state and the game played in the internal replay selection high state, the player can display the second replay selection high state. Since it becomes more difficult to discriminate whether the game is being played in the selected high state or the game in the internal replay selected high state, it gives the player a stronger expectation to advance to the winning game Can be expected to maintain and increase the player's interest in the game.

  In the slot machine according to the present invention, a plurality of roles are set as the predetermined role that is a start requirement of the second replay high state, and the first replay is in the replay selection high state. In the selected high state, when a predetermined start requirement different from the start requirement of the second replay high state is satisfied, the first replay selected high state is canceled and the third game starts from the next game. The maximum number of games that are included in the replay selection high state and that can be continuously performed in the third replay selection high state can be continuously performed in the second replay selection high state. It is conceivable that the value is larger than the number of times.

  Here, as a requirement for starting the third replay selection high state, for example, in the first replay selection high state, winning a role that is a lottery drawing or winning a certain role is a requirement The roles that can be set and applied include all roles including a replay role and a general role. In addition, it may be a requirement to play a predetermined number of games.

  In the present embodiment, the third regame selection high state is a game state that is more advantageous for the player because the game can be continued longer than the second regame selection high state. Moreover, in this embodiment, there are a case where a transition is made from the first regame selection high state to a second regame selection high state, and a case where a transition is made to a third regame selection high state which is more advantageous for the player. Is set. Therefore, since the player has an interest in which re-game selection high state to shift to, it can be expected that the player will be nervous about the progress of the game, and the player's interest in the game will be increased. Further, when the possibility of shifting to the third replay selection high state that is more advantageous to the player is high, it can be expected that the player's interest in the game is further increased and maintained.

In the slot machine according to the present invention, when it is determined that the symbol corresponding to the winning combination has stopped and won in the internal state, a winning game that is advantageously advanced from the next game to the player is performed. It is conceivable that the predetermined start requirement of the first re-game selection high state includes winning game control means and that the winning game has ended.
In this embodiment, since the re-game selection high state that is also advantageous for the player is continued following the hit game that makes the game proceed in an advantageous manner for the player, it is possible to increase and maintain the player's interest in the game. I can expect.

  According to the above-described invention, in the combination lottery, the winning combination and the predetermined combination that is the start requirement of the second replay selection high state may be won at the same time. It is difficult to determine whether it will shift to the second replay selection high state or the internal medium replay selection high state when the winning combination is given, and give the player a sense of tension regarding the progress of the game In addition, since it is possible to give a player a sense of expectation that the player will progress to the game, it is expected that the player's interest in the game is increased and maintained. Further, by displaying the same effect image in the second re-game selection high state and the internal medium re-game selection high state, it is possible to give a player a stronger sense of expectation to advance to a win game.

  Furthermore, it is set so that there is a case where a transition is made from the first replay selection high state to a second replay selection high state, and a case where a transition is made to a third replay selection high state which is more advantageous for the player. Accordingly, it can be expected that the player is given a sense of tension regarding the progress of the game and the player's interest in the game is increased. Further, when the possibility of shifting to the third replay selection high state that is more advantageous to the player is high, it can be expected that the player's interest in the game is further increased and maintained.

  When the player tilts the start switch 50, the three reels 40L, 40C, and 40R described above start to rotate all at once. When the rotational speeds of the reels 40L, 40C, and 40R reach a constant speed, the operation of the stop switches 52L, 52C, and 52R by the player becomes effective.

  When the player pushes the stop switch 52L, the left reel 40L stops. When the stop switch 52C is pushed, the middle reel 40C stops. When the stop switch 52R is pushed, the right reel 40R stops.

  When each reel 40L, 40C, or 40R is stopped, stop control is performed so that the symbols drawn on the outer peripheral surfaces are positioned on the above five winning lines L1, L2A, L2B, L3A, and L3B. .

  On the lower right side of the casing of the slot machine 10 is a sound output from a speaker (not shown) housed in the casing (corresponding to a speaker 64 shown in FIG. 4 described later) to the outside of the casing. A sound transmission hole 60 is provided. A game medium payout port 62 is provided at a central portion below the casing of the slot machine 10. When each reel 40L, 40C or 40R stops, the combination of symbols stopped and displayed on the active line becomes a predetermined combination, that is, the combination of symbols constituting the winning combination. Accordingly, a predetermined number of game media are paid out from the game media payout opening 62.

  As described above, the game in the slot machine 10 is such that a game result is determined by a combination of symbols of the plurality of reels 40L, 40C, or 40R stopped. This game is performed every time the player tilts the start switch 50, and the process from the start of rotation to the stop of rotation of the reels 40L, 40C, or 40R can be repeated as one unit of game. .

  Examples of the types of combinations described above include types such as winning combinations, general combinations, and re-playing combinations. The winning combination is a combination in which when a winning combination is won by lottery and when a winning combination is awarded according to the winning combination, a winning game that allows the player to advance the game advantageously can be performed. Further, the general combination is a combination of paying out a predetermined number of game media when a general combination is won by lottery and a symbol corresponding to the general combination is won. In this general combination, it is possible to set a single combination in which one game medium is paid out when winning. In addition, when a re-gamer wins a re-game player by lottery and wins all the symbols according to the re-game player, a re-game (also referred to as replay) is performed without newly inserting a game medium. It is a role that can. It is also possible to set a plurality of types of re-game players.

  The winning combinations include a big bonus combination (hereinafter referred to as BB combination) and a regular bonus combination (hereinafter referred to as RB combination). The RB combination is a combination that shifts to the RB game that is the first winning game. In this RB game, a game in which a predetermined combination is won with a high probability is performed a predetermined number of times under a certain condition. On the other hand, the BB role is a role that shifts to the BB game that is the second winning game, and the BB game can perform a general game and can shift to an RB game under a certain condition during the general game. Thus, the general game and the RB game can be repeatedly performed until a predetermined number of game media payouts is reached. Here, it is also possible to set a plurality of BB games. For example, it is possible to provide a plurality of BB games with different end number settings.

Do. FIG. 16 shows an effect control subroutine performed by effect control means 540, image control means 510, and sound control means 520.

  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 S11). Here, the NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is larger than 0, and replay is not performed when it is 0 or less. Further, as shown in step S 172 of FIG. 14, when the re-game player 1 is won and won, 1 is input as the NRP value, and as shown in step S 173 of FIG. When 2 wins and wins, 2 is input as the NRP value.

  If it is determined in step 11 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 has been inserted (step). S12). If it is determined in this determination that a game medium has been inserted (YES), the process proceeds to step S15, and the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the number of bets. To do. However, when the number of game media exceeding the specified number (three in this embodiment) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits.

  If it is determined in step S12 that no game medium is inserted (NO), it is next determined whether or not there is a credited game medium (step S13). 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 S13 are repeated.

  If it is determined in step S13 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S14). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34 and 36. If it is determined in this determination that the bet operation signal has not been received (NO), the process returns to step S12 again, and the determination processing from step S12 to step S14 is repeatedly executed. If it is determined in step S14 that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S15). 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, A process of subtracting the number of credits of the game medium by the number of detected bets is performed (step S16). Then, the process proceeds to a combination lottery processing subroutine (step S18).

  If it is determined in step S11 that the value of NRP is greater than 0 (YES) and the player is in the replaying state, 0 is input to the value of NRP to cancel the replaying state (step S17). A re-game control process that does not perform the process from S12 to step S16 is performed, and the process proceeds to a combination lottery process subroutine (step S18). 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 re-game is controlled so as to set the same bet number as the bet in the previous game. However, a bet number different from the bet number in the previous game is set. It is also possible to perform control.

  In the combination lottery processing subroutine of step S18, combination lottery is performed by the combination lottery means 410, and a flag-on process for turning on the RB flag, the BB 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 role lottery processing subroutine (step S18), on the basis of the result of the role lottery, the reel variation and stop subroutine (step S19) for performing control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, 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 winning determination and flag off processing subroutine (step S20) for performing flag-off processing is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S21) 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 above control process. 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 S18 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 S31). 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. Perform (see step S73 in FIG. 8).

  If it is determined that the start switch ON signal is not received (NO), the determination process in step S31 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 S31 that a start switch ON signal has been received (YES), a game start signal is transmitted to the sub-control circuit 200 (step S32). In the sub control circuit 200, based on the game start signal transmitted in step S32, the determination process (see FIG. 16) in step S201 of the effect control subroutine is performed.

  Subsequently, it is determined whether or not the value of the parameter NRB is greater than 0 (step S33). Here, the NRB is a parameter that determines whether or not to play an RB game, and is set so as to play an RB game when it is larger than 0, and not play an RB game when it is less than 0. Further, as shown in step S125 in FIG. 11 and step S164 in FIG. 13, when the RB combination is won and won, 1 is input as the NRB value.

  If it is determined in step S33 that the NRB value is greater than 0 (YES), the RB lottery table stored in the ROM 108 is read (step S34), and the process proceeds to step S49. Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, three types of general combinations of symbol numbers 1 to 3 and a deviation of symbol number 4 are set. If the winning combination in the lottery is 1/80 and the symbol on the left reel is cherry, the general combination 1 with symbol number 1 wins the symbol on any of the remaining two reels. Is set to

  The general combination 2 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1 / 1.03 and all three reels have the same bell symbol. Therefore, during the RB game, the possibility of winning the general combination 2 in the combination lottery is very high. Further, the general combination 3 with the symbol number 3 is set to win when the winning probability in the combination lottery is 1/100 and the three reels have the same watermelon symbol. The probability of symbol number 4 falling is set to a low value of about 1/100.

  If it is determined in step S33 that the NRB value is 0 or less (NO), it is next determined whether or not the parameter NBB value is greater than 0 (step S35). 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 S162 of FIG. 13, when the BB combination is won and won, 1 is input as the value of NBB.

  If it is determined in step S35 that NBB is larger than 0 (YES), the general lottery table for BB operation stored in the ROM 108 is read (step S36), and the process proceeds to step S49. Here, an example of the general lottery table during BB operation is shown in FIG.

  The general lottery table during BB operation is a lottery table used when the BB game is in progress and not in the RB game. If the BB game is being played and the RB game is being played, the RB lottery table shown in FIG. 17 is used. In the general lottery table at the time of BB operation, three types of general combinations of symbol numbers 1 to 3, an RB combination of symbol number 4 and a deviation of symbol number 5 are set. Here, in comparison with the general lottery table for RT operation (FIGS. 19 to 22) and the general lottery table for BB non-operation (see FIG. 23) described later, in the general lottery table for BB operation, There is no setting.

  If the winning combination in the lottery is 1/80 and the symbol on the left reel is cherry, the general combination 1 with symbol number 1 wins the symbol on any of the remaining two reels. Is set to Further, the general combination 2 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1/5 and all three reels have the same bell symbol. The general combination 3 with symbol number 3 is set to win when the winning probability in the combination lottery is 1/100 and all three reels have the same watermelon symbol.

  The RB role with symbol number 4 is set to win when the winning probability in the role lottery is 1/4, the bar symbol stops on the left reel, and the replay symbol stops on the right reel. ing. In the BB non-operating general lottery table to be described later (see FIG. 23), the winning probability of the RB combination in the combination lottery is 1/600, and the probability of winning the RB combination is higher during the BB game than during the normal game. Is set. In addition, the probability of losing symbol number 5 in the role lottery is set to about 1 / 1.90.

  Next, when it is determined in step S35 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 S37). 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.

  The NRT is set to 0 in the initial state, and when the RT operation state start requirement is satisfied, the values of 1 to 4 of the NRT are input to set each RT operation state. Specifically, when the RB game or the BB game ends, 1 is input to the value of NRT (see step S107 in FIG. 10 and step S132 in FIG. 11) to set the RT1 operation state, and RT1 In the operating state or the normal gaming state, when one of the one-piece roles 1 to 12 described later wins, the NRT value 2 is input (see step S183 in FIG. 15) to set the RT2 operating state. Do. In the RT1 operating state or the normal gaming state, when a re-game player 2 to be described later wins, 3 is input to the value of NRT (see step S174 in FIG. 14) to set the RT3 operating state. Further, when the RB combination or BB combination is won in the combination lottery and the RB and BB flags are set (when the internal state is reached), 4 is input to the value of NRT (see step S54 in FIG. 7). The internal RT operating state is set.

  When the requirements for canceling the RT operation state are satisfied in the RT operation state, specifically, when the RB combination or the BB combination wins in all the RT operation states (see step S166 in FIG. 13), or RT1 to RT1 When the number of games reaches a predetermined number in the RT3 operating state (see step S43 in FIG. 6), 0 is input to the value of NRT to cancel the RT operating state.

  If it is determined in step S37 that the value of NRT is greater than 0 (YES), it is next determined whether or not the value of NRT is 4 (step S38). In this determination, if it is determined that the NRT value is not 4 (NO), it is determined that the NRT value is 1 to 3, and then the NRTn operation general lottery table corresponding to the NRT value ( n = 1 to 3) is read from the ROM 108 (step S39). Further, as will be described later, when it is determined in step S38 that the value of NRT is 4 (YES), the internal lottery table during internal RT operation is read from the ROM 108 in step S46. Here, FIG. 19 to FIG. 21 show examples of the general lottery table for operating RT1 to RT3, and FIG.

  In each RT operation general lottery table (FIG. 19 to FIG. 22), the set combination and symbol are the same, and three types of general combination of symbol numbers 1 to 3 and one symbol number 4 to 15 The combination of the combination 1 to 12, the replaying role 1 of the symbol number 16, the replaying role 2 of the symbol number 17, the RB role of the symbol number 18, the BB role of the symbol number 19, and the symbol number 20 are set. ing. Compared to the BB non-operating general lottery table (see FIG. 23) described later, all the roles and symbols set in RT1 to RT3 and the internal medium RT operating general lottery table are the BB non-operating general lottery table. It is the same as the role and symbol set in the table.

  Also, in each RT operation general lottery table (FIGS. 19 to 22), the difference is that the replaying combination 1 of the symbol number 16, the replaying combination 2 of the symbol number 17, and the symbol number 20 are different. It is the winning probability in the role lottery. In addition, the difference between each RT operation general lottery table (see FIG. 19 to FIG. 22) and the BB non-operation general lottery table (see FIG. 23) is also the same. The winning probabilities of the 17 replaying game 2 and the winning combination lottery of the symbol number 20 are. In the following, each RT operation general lottery table (FIGS. 19 to 22) will be described in the order of symbol numbers.

  The three types of general combinations of symbol numbers 1 to 3 are set to be the same in the above-described general lottery table during BB operation (see FIG. 18), the winning probability, and all symbols. That is, for the three general roles of symbol numbers 1 to 3, the BB operation general lottery table (see FIG. 18), the RT operation general lottery tables (FIGS. 19 to 22), and the BB non-operation general lottery In the table (FIG. 23), the winning probabilities and symbols are all set identically.

  For each of the winning combinations 1 to 12 of symbol numbers 4 to 15, the winning probability in the winning lottery is set to 1/240, and the symbols as shown in FIGS. 19 to 22 are stopped in each reel. Sometimes set to win. Therefore, the winning probability in the winning lottery is 1/20 for the entire winning combination. Note that the single combination is a kind of general combination and is a combination in which one game medium is paid out when winning. Note that the symbols shown in FIGS. 19 to 22 are merely examples, and any other symbols can be used as long as the combination of symbols for each one is different.

  In the re-game combination 1 with the symbol number 16, the winning probability in the combination lottery is 1/7 in the RT1 operation state (see FIG. 19), 1/2 in the RT2 operation state (see FIG. 20), and 1/1 in the RT3 operation state. .5 (refer to FIG. 21), set to 1 / 2.5 (refer to FIG. 22) in the internal operation state, and is set to win when all three reels have replay symbols. In the BB non-operating general game table (see FIG. 23), which will be described later, the probability that the re-game player 1 will win in the role lottery is set to 1 / 7.3. As is clear from the comparison of the winning probabilities of the re-game player 1 in FIGS. 19 to 23, the re-game player 1 wins in the role lottery in the RT1 operation state (see FIG. 19) and the normal game state (see FIG. 23). The probability of doing does not change greatly. That is, in the RT1 operation state (see FIG. 19), the player plays the game without feeling much of the change from the normal game (see FIG. 23).

  In RT2, RT3, and the internal RT operating state, the probability that the re-gamer 1 is won in the role lottery is considerably higher than that in the normal game state. If the RT operating states are arranged in the descending order of the winning probability of the re-gamer 1, the RT3 operating state (probability 1 / 1.5: see FIG. 21), RT2 operating state (probability 1/2: see FIG. 20), internal The order is the middle RT operating state (probability 1 / 2.5: see FIG. 22). However, since the difference between the winning probabilities is not so large, it is difficult for the player to discriminate which RT operating state, even though it can be identified that the RT operating state. For example, it is considered that it is difficult for the player to determine whether the game is in the RT2 operating state or the internal RT operating state only by the progress of the game.

  In the re-game combination 2 with the symbol number 17, the winning probability in the combination lottery is set to 1/80 (see FIG. 19) at RT1, 1/65536 (see FIGS. 20 to 22) in RT2, RT3, and inside. The left and middle reels are set to win when the replay symbol stops and the right reel stops the watermelon symbol. In the BB non-operating general game table (see FIG. 23), which will be described later, the probability that the re-game player 2 will win in the role lottery is set to 1/65536. As is clear from the comparison of the winning probabilities of the re-gamer 2 in FIGS. 19 to 23, the RT2 operating state (see FIG. 20), the RT3 operating state (see FIG. 21), the internal RT operating state (see FIG. 22), And in the normal game state (see FIG. 22), it is very rare to win replay 2 in the role lottery. However, when RT1 is activated (see FIG. 19), It can be said that there is a case to win.

  In addition, the RB combination with the symbol number 18 is set to win when the winning probability in the combination lottery is 1/600 and all three reels have the blue 7 symbol. The BB combination with symbol number 19 is set to win when the winning probability in the combination lottery process is 1/300 and all three reels have 7 red symbols. As is clear from comparison of FIGS. 19 to 23, for each of the RB role and the BB role, in each RT operation general lottery table (FIGS. 19 to 22) and BB non-operation general lottery table (FIG. 23), The winning probability and the symbol are all set the same.

  The winning probability in the winning lottery of the symbol number 20 is about 1 / 1.76 (see FIG. 19) in the RT1 operating state, about 1 / 4.49 (see FIG. 20) in the RT2 operating state, and about RT in the RT3 operating state. 1 / 17.9 (refer to FIG. 21), and set to 1 / 3.10 (refer to FIG. 22) in the internal operation state.

<Explanation of duplicate winners in role lottery>
In the present embodiment, the number is set so that the single combination 1 to 12 with symbol numbers 4 to 15 and the RB combination with symbol number 18 or the BB combination with symbol number 19 may be won simultaneously in the combination lottery. Has been. In other words, for the numbers set for each combination for use in the lottery process, there is an area where the number set for one combination 1 to 12 and the number set for the RB combination or BB combination overlap. It is set to be. This is schematically shown in FIG. As shown in FIG. 24, for example, the number area set for the single winning combination 1 partially overlaps the number area set for the RB winning combination. Similarly, for example, the number area set for the single combination 2 and the number area set for the BB combination partially overlap. Therefore, if the random number extracted in the combination lottery process is a value within this overlapping area, two combinations will be won.

  In the present embodiment, it is possible to set all the one-piece combinations 1 to 12 so that the numbers of the RB combination or the BB combination overlap. In FIG. 24, for the sake of clarity, a part of the consecutive numbers is drawn so as to overlap, but it is also possible to set the numbers set to be overlapped. Due to such overlapping setting of numbers, there may be a case in which the winning combination of 1 to 12 and the winning combination of RB or BB are simultaneously won in the winning combination.

  Here, as will be described later, in the RT1 operating state, when any one of the 1-sheet winning combinations 1 to 12 wins and wins in the winning lottery, the RT2 operating state is changed (see step S183 in FIG. 15). . When the winning combination of the RB combination or the BB combination is won in the combination lottery, the internal RT operation state is changed (see step S54 in FIG. 7). Further, as described above, the winning probability (1/2) of the replaying player 1 when the RT2 is activated and the winning probability (1 / 1.5) of the replaying player 1 when the internal RT is working are not much different. Therefore, it is difficult for the player to determine which RT is operating from the progress of the game.

  Further, as will be described later, by displaying the same effect image during RT2 operation and during internal RT operation, it becomes more difficult for the player to determine which RT is operating. In addition, the RT2 operation state ends when a maximum of 5 games are played (see step S43 and step S184 in FIG. 15), while in the internal operation state, the game shifts to a winning game if the winning combination wins. (See steps S162 and 164 in FIG. 13), there is a great difference between the two RT operating states in terms of whether or not the game proceeds favorably for the player. Therefore, by setting as described above, it is possible to give the player a sense of tension regarding the progress of the game, and to give the player a sense of expectation to proceed to the game. It can be expected to maintain high.

  Returning to the description of the flowchart, following step S39, it is determined whether or not the value of NRT is 2 (step S40). In this determination, if it is determined that the value of NRT is 2 (YES), that is, if it is determined that the RT2 is in the operating state, then the RT2 operating signal is transmitted to the sub-control circuit 200 (step). S41), the process proceeds to step S42. The sub-control circuit 200 performs the determination process (see FIG. 16) in step S202 of the effect control subroutine based on the RT2 operation signal transmitted in step S41. If it is determined in step S40 that the value of NRT is not 2 (NO), the process directly proceeds to step S42.

  In step S42, a control process for adding 1 to the value of RTKAISU is performed (step S42). Here, RTKAISU is a counter for counting the number of games in the RTn operating state (n = 1 to 3). Also, RTMAXn (n = 1 to 3) used in the determination process in step S43 below is the maximum number of games played in the RTn operating state (n = 1 to 3).

  When setting the RT1 operation state, 1 is input to the value of RTKAISU and 60 is input to the value of RTMAX1 (see step S108 in FIG. 10 and step S133 in FIG. 11). Further, when setting the RT2 operation state, 1 is input to the value of RTKAISU and 5 is input to the value of RTMAX2 (see step S184 in FIG. 15). Further, when setting the RT3 operating state, 1 is input to the value of RTKAISU and 100 is input to the value of RTMAX3 (see step S175 in FIG. 14).

  Subsequent to step S42, it is determined whether or not the value of RTKAISU is greater than RTMAXn (n = 1 to 3) (step S43). If it is determined in this determination that the value of RTKAISU is greater than RTMAXn (YES), 0 is input to the NRT value to release the RTn operating state (step S44), and 0 is input to the RTKAISU value. Initialization (step S45) proceeds to step S49. If it is determined in step S43 that the value of RTKAISU is equal to or less than RTMAXn (NO), the process proceeds to step S49 without releasing the RTn operating state.

  As described above, when the RTn operation state (n = 1 to 3) is set, 1 is input to the counter RTKAISU for controlling the number of games in the RTn operation state, and whenever a game is performed in the RTn operation state, Then, a control process for adding 1 to the value of RTKAISU is performed. Then, when the value of RTKAISU becomes larger than RTMAXn, that is, when RTMAXn games are played in the RTn operating state, a control process for releasing the RTn operating state is performed.

  In this embodiment, as will be described later, when any one of the general roles 1 to 12 wins in the RT1 operating state or the normal gaming state, the gaming state is changed to the RT2 operating state (see step S183 in FIG. 15). When the re-game player 2 wins in the RT1 operating state or the normal gaming state, the gaming state is changed to the RT3 operating state (see step S174 in FIG. 14). In addition, the maximum number of games in the RT2 operating state is 5 (RTMAX2 = 5), and the maximum number of games in the RT3 operating state is 100 (RTMAX2 = 100). In either RT operating state, the probability of winning the re-gamer 1 in the role lottery is set to be very high compared to the normal gaming state, but compared to the two RT operating states, RT3 operation In the state, the probability of winning the re-gamer 1 in the role lottery is set higher.

  Therefore, the game proceeds more advantageously for the player when the RT1 operation state is shifted to the RT3 operation state. Here, the winning probability in the combination lottery of the general combination 1 to 12 in the RT1 operating state is 1/20, and the winning probability in the combination lottery of the replaying combination 1 in the RT1 operating state is 1/80. Therefore, in the RT1 operation state, the possibility of winning the general combination 1-12 in the combination lottery is higher than the possibility of winning the re-game combination 1. However, even if any one of the general roles 1 to 12 is won in the role lottery, it is assumed that the symbols as shown in FIG. 19 do not stop on each reel. In that case, the player It can be expected that the re-game player 1 wins before any one of the general winnings 1 to 12 wins. Here, since the game can be performed up to 60 times in the RT1 operation state, it is considered that there is a sufficient possibility to shift to the RT2 or RT3 operation state during that time.

  Next, returning to the determination in step S38, when it is determined that the NRT value is 4 (YES), that is, when it is determined that the internal medium RT operation state is established, the internal medium RT operation state stored in the ROM 108 in general. The lottery table (see FIG. 22) is read (step S46). As described above, since the description of the internal lottery table in the RT operation state general lottery table has already been made, further explanation is omitted. Subsequent to step S46, an internal RT operation signal is transmitted to the sub-control circuit 200 (step S47), and this subroutine is terminated. The sub-control circuit 200 performs the determination process (see FIG. 16) in step 203 of the effect control subroutine based on the internal RT operation signal transmitted in step S47.

  Next, returning to the determination of step S37, if it is determined that the value of NRT is 0 or less (NO), the general lottery table for when the BB is not operating stored in the ROM 108 is read (step S48), and step S49. Proceed to 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 the normal gaming state, as described above, and includes three types of general combinations of symbol numbers 1 to 3 and one single combination 1 of symbol numbers 4 to 15. -12, re-playing role 1 of symbol number 16, re-playing role 2 of symbol number 17, RB role of symbol number 18, BB role of symbol number 19, and divergence of symbol number 20 are set .

  For the three types of general roles of symbol numbers 1 to 3, the 1-sheet roles 1 to 12 of symbol numbers 4 to 15, the RB role of symbol number 18, and the BB role of symbol number 19, the above-mentioned general lottery during each RT operation The table (see FIG. 19 to FIG. 22) and the setting of the winning probability and symbol in the role lottery are the same.

  The re-game combination 1 with the symbol number 16 is set to win when the winning probability in the combination lottery process is 1 / 7.3 and all three reels have the replay symbols. The replaying game 2 with the symbol number 17 has a very small value of 1/65536 in the winning lottery process, and when the replay symbol is stopped on the left and middle reels and the watermelon symbol is stopped on the right reel, It is set to be.

  The RB role of symbol number 18 is set to win when the winning probability in the role lottery process is 1/600 and all three reels have the blue 7 symbol, and it is set to win. The chance of winning a role is low. The BB combination with symbol number 19 is set to win when the winning probability in the combination lottery process is 1/300 and all three reels have the red 7 symbol. Further, the probability in the extra lot drawing is set to about 1 / 1.71.

  As described above, after the lottery table corresponding to the state of the game is read out, the role lottery for acquiring the random number and performing the lottery determination is performed (step S49). 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.

  Then, the process proceeds to FIG. 7 following FIG. 6, and it is determined whether or not the RB combination is won as a result of this determination (step S50). If it is determined that the RB combination is won (YES), the RB combination flag is turned on and stored in the RAM 110 (step S51), and the process proceeds to step S54.

  If it is determined in step S50 that the RB combination is not won (NO), it is next determined whether or not the BB combination is won (step S52). In this determination, if it is determined that the BB combination is won by the combination lottery (YES), the BB combination flag is turned on and stored in the RAM 110 (step S53), and the process proceeds to step S54. In step S54, 4 is input to the NRT value to set the RT4 operating state (step S54), and the process proceeds to step S61.

  If it is determined in step S52 that the BB combination is not won (NO), it is next determined whether or not the re-game combination is won (step S55). If it is determined in this determination that the re-gamer has been won by the winning lottery (YES), it is next determined whether or not the re-gamer 1 has been won (step S56). If it is determined in this determination that the re-game player 1 has been won (YES), the re-game 1 flag is turned on and stored in the RAM 110 (step S57), and the process proceeds to step S61. If it is determined in step S56 that re-gamer 1 has not been won (NO), it is determined that re-gamer 2 has been won, and the re-game 2 flag is turned on and stored in RAM 110. (Step S58), the process proceeds to Step S61.

  If it is determined in step S55 that the re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S59). If it is determined in this determination 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 S60), and the process proceeds to step S61. If it is determined in step S59 that the general combination is not won (NO), the flag-on process is not performed and the process proceeds to step S61.

  After performing a series of processing related to flag-on as described above, in step 61, 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. The combination lottery processing subroutine is thus completed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the above-described combination lottery processing subroutine (step S18) is completed, a reel fluctuation and stop subroutine (step S19) is then performed. 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 S61 in FIG. 7 are read (step S71). Then, it is determined whether or not a predetermined shortest time has elapsed (step S72). If it is determined in this determination that the shortest time has not elapsed (NO), the determination process in step S72 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 S72 that the shortest time has elapsed (YES), the start switch ON signal has already been received (see step S31 in FIG. 6), so the reel rotation start signal is sent to the motor drive circuit. 114, the rotation of the motors 80L, 80C, 80R is started, and the reels 40L, 40C, 40R are rotated (step S73).

  Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S74). If it is determined in this determination that the reel has not yet rotated at a constant speed (NO), the determination process in step S74 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 S74 that the reel is rotating at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S75). 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 S75 that a reel stop signal has been received (YES), the reel control means 440 performs reel symbol combination control (stop control) corresponding to the stop switch that has transmitted the reel stop signal. (Step S76), the process proceeds to Step S77.

  Here, the control processing in steps S75 and S76 will be described in more detail. When the stop switch 52L for the left reel is pushed, the reel control means 440 uses the motor 80L that rotates the left reel 40L. Stop control in step S76 is performed. Similarly, when the stop switch 52C for the middle reel is pushed, the stop control in step S76 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 S76 is performed for the motor 80R that rotates the right reel 40R.

  In the symbol combination control (stop control), based on the symbol number and control symbol data read out in step S71, the reel is slid for a maximum of four frames so that a predetermined symbol is stopped or not stopped within the range. Motor stop control is performed. Further detailed description of the control is omitted.

  If it is determined in step S75 that the reel stop signal has not been received (NO), the control proceeds to step S77 without performing control related to the stop. In step S77, it is determined whether all reels have stopped.

  If it is determined in this determination that all the reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S78). If it is determined in this determination that the time limit has not been reached (NO), the process returns to step S75 and the control processing from step S75 to step S78 is repeated. As described above, until all the reels stop or until the time limit elapses, the process of performing symbol combination control (stop control) of the corresponding reels is repeated every time the reel stop signal is received.

  If it is determined in step S78 that the time limit has elapsed (YES), automatic symbol stop control is performed on reels that are still rotating to stop all reels (step S79), and this subroutine is executed. finish. In this automatic symbol stop control, the maximum four symbol (four frames) stop positions can be shifted, and stop control is performed so that the winning symbols are not always aligned within the range. Next, returning to the determination in step S77, if it is determined that all the reels are stopped (YES), this subroutine is terminated as it is.

<Description of Flag Off, RT Setting Subroutine>
In the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S19) is completed, a flag-off / RT setting process subroutine (step 20) 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 is RB game (step S91). If it is determined in this determination that the RB game is being played (YES), an RB game process subroutine (step S92) is performed, and the flag off and RT setting process subroutine is terminated. A detailed description of the RB game processing subroutine will be described later.

  If it is determined in step S91 that the game state is not RB game (NO), it is next determined whether or not the game state is BB game (step S93). If it is determined in this determination that the BB game is being played (YES), a BB game processing subroutine (step S94) is performed, and the flag-off and RT setting process subroutine is terminated. A detailed description of the BB game processing subroutine will be described later.

  If it is determined in step S93 that the game state is not BB game (NO), it is next determined whether or not there is a winning combination (step S95). If it is determined in this determination that there is a winning combination (YES), a winning combination processing subroutine (step S96) is performed, and the flag off and RT setting processing subroutine is terminated. A detailed description of the winning combination processing subroutine will be described later.

  If it is determined in step S95 that there is no winning combination (NO), a general processing subroutine (step S97) is performed, and the flag off and RT setting processing subroutine is terminated. Details of the general processing subroutine will be described later.

  Hereinafter, a detailed description of the subroutine shown in steps S92, S94, S96, and S97 will be given.

<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S92) executed when it is determined in step 91 that the RB game is being performed will be described with reference to the flowchart shown in FIG.

  First, it is determined whether or not the reel symbol stopped by the reel fluctuation / stop subroutine described above has won a prize (step S101). Next, the game count and the winning count are counted, the game count and winning count data are updated, and the updated data is stored in the RAM 110 (step S102). These data are used as the RB game end condition. When the number of games or the number of winnings reaches a predetermined number, the RB game is ended.

  Next, it is determined whether or not a BB game is being played (step S103). If it is determined in this determination that the BB game is being played (YES), that is, the BB game is being played in the RB game, the payout number is counted to update the payout number data, and the updated data is stored in the RAM 110. (Step S104). This data is used as a BB game end condition. When the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition is achieved (step S105). In this determination, if it is determined that the BB game end condition is achieved (YES), 0 is input to the values of NBB and NRB, and the RB game state and the BB game state are canceled (step S106). ), Go to step S107.

  If it is determined in step S105 that the BB end condition is not achieved (NO), it is next determined whether or not the RB end condition is achieved (step S109). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S110), and the process proceeds to step S107. If it is determined in step S109 that the RB end condition is not achieved (NO), the RB gaming state is not released and the present subroutine is ended.

  Returning to the determination in step S103, if it is determined that the BB game is not being played (NO), it is next determined whether or not the RB end condition is achieved (step S111). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S112), and the process proceeds to step S107. If it is determined in step S111 that the RB end condition has not been achieved (NO), the RB gaming state is not released and the present subroutine is ended.

  In step S107, 1 is input as the value of NRT to set the RT1 operating state (step S107). Next, 1 is input to the value of the counter RTKAISU for counting the number of games in the RT1 operating state. 60 is input to the value of the maximum number of games RTMAX1 at (step S108), and this subroutine is terminated.

<Description of processing subroutine during BB game>
Next, FIG. 11 shows a detailed explanation of the BB game processing subroutine (see step S94) executed when it is determined in step S93 that the BB game is being played in the flag off / RT setting processing subroutine (see FIG. 9). This will be described with reference to the flowchart shown.

  First, it is determined whether or not a reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S121). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S122). If it is determined in this determination that there is no winning (NO), if any flag is turned on, the flag is turned off (step S123), and the process proceeds to step S129. If it is determined in step S122 that there is a winning (YES), it is then determined whether or not the RB combination has won (step S124). If it is determined in this determination that the RB combination has won (YES), 1 is input as the NRB value to set the RB gaming state (step S125). Then, the RB flag is turned off (step S126), 0 is input to the value of NRT to cancel the RT operation state (step S127), and the process proceeds to step S129.

  If it is determined in step S124 that the RB combination has not won (NO), the general combination flag is turned off (step S128), and the process proceeds to step S129.

  In step S129, the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110. This data is used as a BB game end condition, and when the payout number reaches a predetermined number, the BB game is ended.

  Next, it is determined whether or not the BB game end condition has been achieved (step S130). 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 S131). Then, 1 is input as the NRT value to set the RT1 operating state (step S132), and then 1 is input to the value of the counter RTKAISU for counting the number of games in the NRT1 operating state, 60 is input to the value of the number of games RTMAX1 (step S133). This subroutine ends. If it is determined in step S130 that the BB termination condition has not been achieved (NO), this subroutine is terminated.

<Explanation of the processing sub-routine for winning the role>
Next, in the flag off / RT setting processing subroutine (see FIG. 9), the detailed explanation of the winning combination processing subroutine (see step S96) executed when it is determined that there is a winning combination in step S95 is a flowchart shown in FIG. Will be described.

  First, it is determined whether or not a reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S141). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S142).

  If it is determined in this determination that a prize has been won (YES), it is next determined whether or not the BB combination or the RB combination has won (step S143). If it is determined in this determination that the BB combination or RB combination has won (YES), the BB / RB determination processing subroutine is performed (step S144), and this subroutine is terminated. A detailed description of the BB and RB determination processing subroutine will be described later.

  If it is determined in step S143 that the BB combination or the RB combination has not won (NO), it is next determined whether or not the re-game combination has won (step S145). If it is determined in this determination that the re-gamer has won (YES), the re-gamer winning process subroutine is performed (step S146), and this subroutine is terminated. A detailed description of the re-game winning combination subroutine will be described later.

  If it is determined in step S145 that the re-game player has not won a prize (NO), it is determined that the player has won the general combination, and the general combination winning process subroutine is performed (step S147). finish. A detailed description of this general combination winning process subroutine will be given later.

  Returning to the determination in step S142, if it is determined that there is no winning (NO), it is next determined whether or not the BB and RB flags are on (step S148). In this determination, if it is determined that the BB and RB flags are turned on (YES), carry-over processing of the BB and RB flags is performed, and the other flags (re-playing game, general game) are turned on. If so, the flag is turned off (step S149), and this subroutine is terminated.

  If it is determined in step S148 that the BB and RB flags are not turned on (NO), the flag turned on (re-playing game, general game) is turned off (step S150). Exit the subroutine.

<BB, RB determination processing subroutine>
Next, in the winning combination processing subroutine (see FIG. 12), a detailed explanation of the BB / RB determination processing subroutine (see step S144) executed when it is determined in step S143 that the BB winning combination or RB winning combination has been won. This will be described with reference to the flowchart shown in FIG.

  First, it is determined whether or not the BB combination has won a prize (step S161). If it is determined in this determination that the BB combination has won (YES), 1 is input as the NBB value to set the BB gaming state (step S162), and the BB flag is turned off (step S163). The process proceeds to step S166.

  Returning to the determination of step 161, if it is determined that the BB combination has not won (NO), it is determined that the RB combination has won, and 1 is input to the value of the NRB to set the RB gaming state. This is performed (step S164). Then, the RB flag is turned off (step S165), and the process proceeds to step S166. In step S166, 0 is input to the value of NRT to release the RT operation state (step S166), and this subroutine is terminated.

<Re-game winning prize processing subroutine>
Next, in the winning combination processing subroutine (see FIG. 12), a detailed explanation of the re-game winning combination subroutine (see step S 146) executed when it is determined that the re-game winning is won in step S145 is shown in FIG. It demonstrates using the flowchart shown in FIG.

  First, it is determined whether or not the re-game player 1 has won a prize (step S171). If it is determined by this determination that the re-game player 1 has won (YES), 1 is input to the value of NRP (step S172), and the process proceeds to step S176. By the control process in step S172, a re-game is performed in which the game is played without inserting the game medium in the next game (see step S11 in FIG. 5).

  If it is determined in step S171 that the re-gamer 1 has not won (NO), it is determined that the re-gamer 2 has won and 2 is input to the value of NRP (step S173). By the control process in step S173, a re-game is performed in which the game is played without inserting the game medium in the next game (see step S11 in FIG. 5).

  Next, it is determined whether or not a game is being performed in a normal game state (a game state in which a general lottery table is read when BB is not activated) or an RT1 operation state (NRT = 1) (step S173A). If it is determined that the game is not being played in the normal game state or the RT1 operation state (NO), the process proceeds to step S176.

  If it is determined in step S173A that the game is being played in the normal gaming state or the RT1 operating state (YES), then, 3 is input to the value of NRT to change the gaming state to the RT3 operating state. (Step S174). Next, 1 is input to the value of the counter RTKAISU for counting the number of games in the RT3 operating state, and 100 is input to the value of the maximum number of games RTMAX3 in the RT3 operating state (step S175), and the process proceeds to step S176. In step S176, the replay flag is turned off. If the BB or RB flag is on, flag carry-over processing is performed (step S176), and this subroutine is terminated.

<General role winning subroutine>
Next, FIG. 15 shows a detailed description of the general winning combination processing subroutine (see step S147) that is executed when it is determined in step S145 that a winning combination has been won in the winning combination processing subroutine (see FIG. 12). This will be described with reference to a flowchart.

  First, it is determined whether or not a game is being performed in a normal gaming state (a gaming state in which a general lottery table is read when BB is not activated) or an RT1 operating state (NRT = 1) (step S181). If it is determined in this determination that the game is not being played in the normal game state or the RT1 operation state (NO), the process proceeds to step S185.

  If it is determined in step S181 that the game is being played in the normal game state or the RT1 operation state (YES), then whether or not any one of the single winning combinations 1 to 12 has won a prize. Is determined (step S182). In this determination, if it is determined that none of the winning combinations 1 to 12 has been won (NO), the process proceeds to step S185.

  If it is determined in step S182 that any one of the winning combinations 1 to 12 has been won (YES), that is, it is determined that any one of the winning combinations 1 to 12 has been won during the RT1 operation. If so, 2 is input to the value of NRT to set the RT2 operating state (step S183). Then, 1 is input to the value of the counter RTKAISU for counting the number of games in the RT2 operating state, and 5 is input to the value of the maximum number of games RTMAX2 in the RT2 operating state (step S184), and the process proceeds to step S185.

  In step S185, the general combination flags (including general combinations 1 to 3 and 1-sheet combinations 1 to 12) are turned off. If the BB and RB flags are on, carry-over processing is performed, and this subroutine is terminated.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S92, S94, S96, and S97 is completed, and the flag-off and RT setting process subroutine shown in FIG. 9 is ended. Here, returning to the main routine of FIG. 5, the flag-off and RT setting processing subroutine in step S20 is terminated, the payout processing in step S21 is terminated, and the 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.

<Direction control subroutine>
Next, the effect control subroutine performed by the sub-control circuit 200 will be described using the flowchart shown in FIG. In this subroutine, control processing for displaying the same internal RT effect image in the RT2 operating state or the internal RT operation state and displaying other effect images in the other gaming states is performed.

  First, it is determined whether or not a game start signal (see step S32 in FIG. 6) has been received (step S201). If it is determined in this determination that the game start signal has not been received (NO), this determination process is repeated. That is, it is in a standby state until a game start signal is received.

  If it is determined in step S201 that a game start signal has been received (YES), it is next determined whether an RT2 operation signal (see step S41 in FIG. 6) has been received from the main control circuit 100 (step S41). Step S202). If it is determined in this determination that the RT2 operation signal has been received (YES), the process proceeds to step S204. If it is determined in step S202 that the RT2 operation signal has not been received (NO), then whether or not the internal RT operation signal (see step S46 in FIG. 6) has been received from the main control circuit 100. (Step S203).

  If it is determined in this determination that the internal RT operation signal has been received (YES), the process proceeds to step S204. If it is determined in step S203 that the internal RT operation signal has not been received (NO), the process proceeds to step S205. In step S204, a control process for displaying the internal RT effect image on the display device 70 is performed (step S204), and this subroutine is terminated. Specifically, the internal RT effect image data is read from the ROM 208 and transmitted to the display drive circuit 220, and an image is displayed on the display device 70.

  Here, the internal medium RT effect image is an effect image that gives the player the impression that the game is in the internal medium state. For example, in a battle using characters, the impression is that the battle situation is dominant and the victory is near. The effect image to attach can be considered. Any other effect image can be used.

  In the present embodiment, the inside / inside RT effect image is displayed not only in the inside / inside RT operating state but also in the RT2 operating state. As described above, since the winning combination 1 to 12 and the winning combination RB or winning combination BB may be won at the same time, it is determined whether the player is in the RT2 operating state or in the internal RT operating state. Is in a difficult situation. In this situation, since the internal / internal RT effect image is displayed, the player can have an expectation that the game is in the internal / internal RT state, and the player's interest in the game can be increased. In addition, when it is determined that the RT2 operation state is determined instead of the internal RT state, the player can be surprised.

  Although not shown in the flowchart, for example, the internal medium RT effect image can be displayed only when a lottery process is won, or the internal medium RT effect image is displayed every predetermined number of games. Can also be displayed.

  In step S205, control processing for displaying other effect images on the display device 70 is performed (step S205), and this subroutine is terminated. Specifically, other effect image data is read from the ROM 208 and transmitted to the display drive circuit 220, and an image is displayed on the display device 70. Here, as the other effect images, any effect image including an effect image using a character can be used.
