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 stoppage. In particular, the present invention relates to a slot machine having a function capable of replaying without inserting game media.

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 lottery is usually performed by the control means, and when a symbol corresponding to the winning combination in the lottery stops and a prize is won, a game in a mode corresponding to the winning combination is performed. Also, in this slot machine, a re-game is set as one of the roles, and when the player is awarded a re-game, the player plays the next game without inserting a new game medium. Some have functions that can. In addition, among the slot machines that can be replayed, in order to increase the player's interest in the game, there is also proposed a slot machine that increases the probability that a re-gamer will be won by lottery when a predetermined condition is met. Has been. (For example, refer to Patent Document 1.)
JP 2001-137430 A

  The slot machine proposed in Patent Document 1 is set so that the probability that a re-game player will be won by lottery at a timing when a predetermined winning game is finished. It has also been proposed to determine whether or not to increase the winning probability of the re-gamer by lottery, and to change the progress of the game. However, the timing of changing the game mode to a state where the winning probability of the re-gamer is high and returning to the original game mode again is the state where the winning probability of the re-gamer is high immediately after the predetermined winning game is finished. After that, when a predetermined number of games have been consumed, the state where the winning probability of the re-gamer is high is canceled. Therefore, if the game is continued for a long time, the game tends to be monotonous, and it is difficult to continue the interest and freshness of the player for a long time.

  The object of the present invention is to solve the above-mentioned problems, change the conditions for releasing the state in which the probability that a re-player is won by lottery is canceled, and further include a gameable content, It is to provide a slot machine that can continue the interest and freshness for a long time.

In order to achieve the above object, as a slot machine according to the present invention, a game in which a game medium is inserted and a plurality of reels on which a plurality of symbols are displayed is rotated and stopped is performed once. A slot lottery means for performing a lottery for determining a single role by lottery from at least a combination including a winning combination and a replaying combination, and a plurality of the reels that have been rotated. Reel control means for performing stop control, control lottery means for performing control lottery for determining one stop control mode by lottery from among the plurality of stop control modes based on the result of the combination lottery, When the winning combination is won by the winning lottery means, if the symbol corresponding to the winning combination is stopped with reference to the result of the stop control, the winning game that advances the game advantageously for the player is performed. A per game control unit Nau, when winning the replay combination by the combination lottery means and replay control means for re-performing the game not turn on the game medium,
When a predetermined start requirement is achieved, the game mode is changed to a re-game selection high state in which the probability that the re-gamer wins is set higher by the role lottery means, and the re-game selection A re-game selection high state control means for releasing the re-game selection high state when a predetermined release requirement is achieved after changing to the high state, and when the predetermined symbol is stopped in the release requirement In the case where releasing the re-game selection high state is included, it is considered that the player can take a means for avoiding the predetermined symbol from being stopped and continuing the re-game selection high state. It is done.

  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.

  Further, the “reel on which the symbol is displayed” includes a reel that is physically rotated and stopped by a motor or the like, and is displayed on the image display device and on the image that is rotated and stopped on the image. A reel is also included.

  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) and a regular bonus combination (hereinafter referred to as RB 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 to be transferred to a BB game which 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. It 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 “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.

  “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. Various other combinations can be added according to the game mode.

  In the “lottery” for determining one combination or the “lottery” for determining the stop control mode, 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.

  With regard to the “predetermined start requirement” for changing to the re-game selection high state, for example, it is possible to set the start requirement that a specific game state such as a winning game has ended. It is also possible to make it a start requirement that a predetermined number of games have been consumed after a predetermined game has ended. It is also possible to make a game-friendly setting based on the requirement that a predetermined winning combination is won and a symbol corresponding to the winning combination is stopped to win. Various other events can be set as start requirements.

  If “predetermined symbol stops” is determined as a re-playing high state release condition, it includes a setting that a predetermined symbol is stopped for all reels, or is predetermined for some reels. The setting that the symbol stops is also included. In addition, the predetermined symbol can be set to the same symbol for all the reels, or a different symbol can be set for each reel.

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

  According to this embodiment, the player can intentionally avoid stopping the predetermined symbol by, for example, a reel stop operation. Therefore, since the player can continue the advantageous gaming state while feeling the gaming fun, it can be expected that the player's interest in the game is increased and continued.

  Further, as a slot machine according to the present invention, in a game where the release of the predetermined symbol is the release condition, when the stop of the predetermined symbol is avoided, the release condition is set to the next game. It is thought that it is not carried over.

  In this embodiment, when the player avoids the stop of the predetermined symbol, the release condition is not carried over to the next game, so that the re-game selection high state advantageous to the player is continuously performed. Can be expected to increase interest in games.

  As the slot machine according to the present invention, it is conceivable that the predetermined symbol is determined by determining one symbol by lottery from a plurality of symbols.

  In this embodiment, it is expected that a game is changed by giving one game a fresh taste by determining one symbol from among a plurality of symbols by lottery.

  The slot machine according to the present invention further includes a display device capable of displaying an effect image, and when the predetermined symbol is stopped, the game is released from the replay selection high state when the predetermined symbol is stopped. It is conceivable to display the effect image (notification image) that can be notified to the display device.

  Here, the “effect image” includes any image as long as it is an image displayed on the image display device. In addition, for example, any image such as a character, a pattern, a color, or a pattern can be applied as an image for notifying that a predetermined role has been won, and still images and moving images are also included. It can also be combined with voice.

  In this embodiment, the notification image allows the player to obtain information related to the predetermined symbol. Based on this information, the player can avoid stopping the predetermined symbol and continue the re-game selection high state. It can be done, and therefore it can be expected to increase the player's interest in the game.

  Further, as the slot machine according to the present invention, it is conceivable that the notification image is not displayed when the number of games exceeds a predetermined number M after changing to the re-game selection high state. In addition, when the number of games for displaying the notification image exceeds a predetermined number N after changing to the re-game selection high state, the notification image may not be displayed.

  In this embodiment, when the predetermined number of times is exceeded, the notification image is not displayed, thereby giving the player an unexpectedness regarding the release of the re-game selection high state and giving a fresh taste about the game. Can be expected.

  As the slot machine according to the present invention, the predetermined number M or the predetermined number N may be determined by lottery. Here, in the “lottery” for determining the values of the predetermined times M and N, 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.

  In this embodiment, by determining the predetermined number of times by lottery, it can be expected that the game is changed and the player is given a fresh taste regarding the game.

  According to the above-described invention, the player can intentionally avoid a predetermined symbol from being stopped by, for example, a reel stop operation. Therefore, since the player can continue the advantageous gaming state while feeling the gaming fun, it can be expected that the player's interest in the game is increased and continued.

  In addition, since the player can obtain information about a predetermined symbol from the notification image, it is possible to prevent the predetermined symbol from stopping based on the information and to continue the re-game selection high state. Therefore, it can be expected to increase the interest of the player in the game.

The control processing by the reel control means 440 is shown in the reel fluctuation, stop subroutine (see FIG. 9) and symbol stop control subroutine (see FIG. 10).

  The winning game control means 450 is advantageous to the player when the winning lottery process determines that the winning symbol and the general symbol are won and the winning symbol determination regarding the symbol that has been stopped determines that the symbols corresponding to each symbol are complete. Payout of a game or a predetermined number of game media that progresses to

  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 symbols that have been re-winned in the lottery process and stopped, the re-game control means 460 immediately before Control for re-implementing the game is performed in a state where the bet number in the played game is maintained. Further, when a predetermined condition is satisfied, a re-game selection high state (hereinafter referred to as RT (abbreviation of replay time) operation state) in which a probability that a re-game player is won in the combination lottery process is set higher is set. It is possible.

  When the re-game selection high state control means 470 achieves a predetermined start requirement, the re-game selection high state control means 470 changes the game mode to a re-game selection high state in which the probability that a re-game player is won by the combination lottery means is set to a higher value. After the change and change to the re-game selection high state, when a predetermined release requirement is achieved, a process for releasing the re-game selection high state is performed.

  The control lottery means 480 performs lottery in the form of reel stop control by control lottery processing. The control lottery means 480 includes, for example, a control lottery random number generator 112B (hard random number, etc.), a random number extraction means 490 for extracting random numbers generated by the random number generator 112B, and a random value extracted by the random number extraction means 490. Random number determination means 495 for determining the mode of stop control selected based on The control process by the control lottery means 480 is shown in the control lottery process subroutine (see FIG. 8).

Do. The image control means 510 can perform control processing for displaying on the image display device 70 an effect image (notification image) for notifying a predetermined symbol that the stop condition is a release condition for the re-game selection high state. This control process is shown in the notification image control subroutine of FIG. The notification image control subroutine also includes a notification frequency lottery process by the notification frequency lottery means 540.

  In the control processing 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. To do.

<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 is performed when a game is performed once, in which one step from when a player inserts a game medium and when a plurality of reels with a plurality of symbols are rotated and stopped is performed once. Indicates.

  First, it is determined whether or not the re-gaming state is set and the re-gaming state is set (step S11). The process of setting the replay state is performed in step S136 of the winning combination process subroutine shown in FIG. 12, as will be described later.

  If it is determined that the re-gaming state is not set (NO), it is next determined whether or not a game medium is inserted (step S12). When it is determined that a game medium has been inserted (YES), the process proceeds to step S14, and the inserted number counted by the game medium counter installed at the lower part of the game medium insertion port 38 is detected as the bet number. 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), the process proceeds to step S12A to determine whether there is a credited game medium. If it is determined that there is no credited game medium (NO), the process returns to step S12 again, and the determination process of steps S12 and S12A is repeatedly executed.

  If it is determined in step S12A that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S13). 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 S13 is repeatedly executed. If it is determined that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S14). 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 S15). Then, the process proceeds to a combination lottery processing subroutine (step S17).

  If it is determined in step S11 that the re-gaming state is set (YES), the re-gaming state setting is canceled (step S16), and the lottery drawing is performed without performing the above-described steps S12 to S15. Proceed to the processing subroutine (step S17). That is, when it is determined that the re-gaming state is set, the game can be played again without newly inserting a game medium or consuming the credited game medium. In addition, since the bet number stored in the RAM 110 is used as the bet number in the re-game, the bet number in the game performed immediately before, that is, the bet number of the game when the re-game player is won by the role lottery process Is used.

  In the combination lottery processing subroutine of step S17, combination lottery processing by the combination lottery means 100 is performed, and flag-on processing for turning on the RB flag, the BB flag, the replay flag, and the general combination flag is performed according to the winning combination. It is. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Subsequent to the role lottery processing subroutine (step S17), a control lottery processing subroutine (step S18) is performed. In this control lottery processing subroutine, a control lottery process is performed by the control lottery means 480, and according to the result of the role lottery process, the stop control mode of one reel is determined and stored. Details of this subroutine will be described later with reference to the flowchart of FIG.

  Next, based on the result of the above-mentioned winning lottery, a reel fluctuation and stop subroutine (step S19) is performed in which control processing related to the movement of the reels that are stopped after the reels 40L, 40C, and 40R are rotated. 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 flowcharts of FIGS.

  Next, after the reels are stopped by the reel change and stop subroutine, a winning symbol determination is performed, and a flag-off process is performed based on the determination result, and an RT operation state (re-game selection high state) is set. For this purpose, a flag off for performing the RT setting process and an RT setting process subroutine (step S20) are 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 at 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 S17 of the main routine will be described in detail with reference to the flowcharts shown in FIGS.
First, it is determined whether or not the game state is an RB game (step S31). If it is determined that the RB game is being played (YES), the RB lottery table stored in the ROM 108 is read (step S32). Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, a winning combination of symbol number 1 and a symbol number 2 are set to be different, and in the case of winning combination, it is set to win when all three reels have JAC symbols. . In the winning lottery performed in step S39, which will be described later, the probability that the winning combination is won is 1 / 1.01, which is set very high. Therefore, the possibility of winning a winning combination during RB gaming is very high. Conversely, the probability of loss is about 1/100, which is set very low.

  If it is determined in step S31 that the game state is not RB game (NO), it is next determined whether or not the game state is BB game (step S33). If it is determined that the BB game is being played (YES), the BB operation general lottery table stored in the ROM 108 is read (step S34). 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 game is BB game and RB game, the RB lottery table shown in FIG. 18 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, compared to the BB non-operating general lottery table (see FIG. 21, details will be described later) used in the normal gaming state that is not the RB gaming state, the BB gaming state, and the re-gaming state, the general lottery during the BB operation In the table, there is no re-game combination and no BB combination.

  If the winning combination probability of the general combination 1 with symbol number 1 is 1/80 and the symbol of the first reel is cherry, the symbol of the remaining two reels will be won regardless of the symbol. It is set to be. The general combination 2 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1/10 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 combination with symbol number 4 is set to win when the winning probability in the combination lottery is 1/4 and all three reels have the replay symbols. In the BB non-operating general lottery table used in the normal gaming state (see FIG. 21), the winning probability of the RB combination in the combination lottery is 1/600, and in the BB game, the RB combination is won compared to the normal time The probability is set very high. In addition, the probability of symbol number 5 losing in the role lottery is set to about 1 / 1.59.

  Next, when it is determined in step S33 that the game state is not BB game (NO), it is next determined whether or not NRT is a value greater than 0 (step S35). Here, the NRT is a parameter for determining whether or not the game state is an RT operation state (regame selection high state) in which a possibility that a re-game is won in the role lottery is higher. NRT is set to 0 in the initial state, and when the start condition of the RT operation state is satisfied, 1 is input as the value of NRT (see step S107 in FIG. 12 and step S125 in FIG. 13). In the RT operating state, when the condition for canceling the RT operating state is satisfied, 0 is input as the value of NRT (see step S42 in FIG. 7 and step S204 in FIG. 16).

  If it is determined that the value of NRT is greater than 0 (YES), the RT operation state has been started, and the RT operation general lottery table stored in the ROM 108 is read (step S36). 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, the three types of general roles of symbol numbers 1 to 3, the replaying role of symbol number 4, the RB role of symbol number 5, the BB role of symbol number 6, and the deviation of symbol number 7 are set The same combination as that in the general lottery table when the BB is not operating (see FIG. 21) used in the normal gaming state is set. For the three types of general combinations of symbol numbers 1 to 3, the above-mentioned general lottery table at the time of BB operation (see FIG. 19) and the general lottery table at the time of BB non-operation (to be described later) (see FIG. 21) The same setting is made for both.

  The re-game combination with the symbol number 4 is set to win when the winning probability in the combination lottery is 1 / 1.5 and all three reels have the replay symbols. In the BB non-operating general game table (see FIG. 21), which will be described later, the probability that the re-gamer will win in the role lottery is set to 1 / 7.3. As is apparent from a comparison between FIG. 20 and FIG. 21, the probability that the re-gamer wins in the role lottery is set to be very high compared to the normal game state during the RT operation.

  In addition, the RB combination with the symbol number 5 is set to win when the winning probability in the combination lottery is 1/600 and all three reels have 7 symbols in blue. The BB combination with symbol number 6 is set to win when the winning probability in the combination lottery process is 1/300 and all three reels have 7 red symbols. The winning probability and the setting of the symbols in the RB role and BB role lottery are the same as those in the general lottery table (see FIG. 21) when the BB is not operating to be described later. Accordingly, as apparent from the comparison between FIG. 20 and FIG. 21, the winning probability in the re-playing role drawing is set higher in the RT operation than in the normal gaming state. The roles are set exactly the same. The probability of losing (about 1 / 4.86) is lower than that in the normal gaming state because the probability that the re-gamer will win is set higher.

  Returning to the description of the flowchart of FIG. 6, when it is determined in step S35 that the value of NRT is 0 or less (NO), the BB non-operating general lottery table stored in the ROM 108 is read (step S38). Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  As already explained, the BB non-operating general lottery table is a lottery table used in the normal gaming state, and includes three general roles of symbol numbers 1 to 3, a re-playing role of symbol number 4, and symbol number 5 RB combination, symbol number 6 BB combination, and symbol number 7 are set off. The three types of general roles of symbol numbers 1 to 3 are the above-mentioned general lottery table at the time of BB operation (see FIG. 19) and the general lottery table at the time of RT operation (see FIG. 20). The same setting is made. The re-game combination with symbol number 4 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. As described above, in the case of RT operation, the winning probability in the combination lottery is set higher than in the normal gaming state.

  The RB combination of symbol number 5 and the BB combination of symbol number 6 are set to be the same as the above-described RT lottery table (see FIG. 20) for both winning probability and symbol setting in the symbol lottery. The probability in the lost role lottery is set to about 1 / 1.36, and the probability of the lost game is set higher because the winning probability of the re-gamer is lower than that in the general lottery table during RT operation.

  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 S39). Specifically, the random number generated by the random number generator 112A is extracted by the random number extraction unit 420, and the random number determination unit 430 compares the extracted random number 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 RB combination is won as a result of this determination (step S <b> 40). 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 S41). Then, a value of 0 is input to NRT (step S42). By inputting 0 to the value of this NRT, even if the game is played in the RT operating state when the RB combination is won, the RT operating state is released from the next game. . Then, the process proceeds to step S49.

If it is determined in step S40 that the RB combination is not won (NO), it is next determined whether or not the BB combination is won (step S43). 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 S44). Then, as in the case where the RB combination flag is on, 0 is input to the value of NRT (step S42), and the process proceeds to step S49.
.

  If it is determined in step S43 that the BB combination is not won (NO), it is next determined whether or not the re-game combination is won (step S45). If it is determined that the re-game combination is won by the combination lottery (YES), the re-game flag is turned on and stored in the RAM 110 (step S46), and the process proceeds to step S49.

  If it is determined in step S45 that the replay is not won (NO), it is next determined whether or not the general combination is won (step S47). If it is determined that the re-game combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step S48), and the process proceeds to step S49.

  If it is determined in step S47 that the general combination is not won (NO), the flag on process is not performed and the process proceeds to step S49.

  After performing a series of processes related to flag-on as described above, in step 49, 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. Further, for use in a later-described notification image control subroutine (see FIG. 17), the selected symbol number and NRT value are transmitted to the sub-control circuit 200 (step S50). The combination lottery processing subroutine is thus completed.

<Control lottery processing subroutine>
When the above-described combination lottery processing subroutine (step S17) is completed in the main routine of FIG. 5, the control lottery processing subroutine (step S18) is then performed. The control lottery processing subroutine will be described in detail using the flowchart shown in FIG.

  First, it is determined whether or not the result of the role lottery is out of place (step S161). If it is not out of date (NO), that is, if it is determined that any winning combination or re-playing combination is won, this subroutine is terminated without performing the control lottery process. If it is determined that the result of the lottery is out of place (YES), it is next determined whether or not the value of NRT is greater than 0 (step S162).

  If it is determined by this determination that the value of NRT is 0 or less (NO), this subroutine is terminated without performing the control lottery process. That is, in the present embodiment, the control lottery process is set to be performed only when the result of the winning lottery is out of order in the RT operating state where the value of NRT is greater than zero.

  If it is determined in step S162 that NRT is greater than 0 (YES), then a control for controlling the lottery stored in the ROM 108 is read (step S163), and a random number is acquired to perform a lottery determination. A lottery process is performed (step S164). Specifically, the random number generated by the random number generator 112B is extracted by the random number extraction unit 490, and the random number determination unit 495 compares the extracted random number with the read lottery table and determines the winning.

  Here, FIG. 22 shows an example of the deviation control lottery table. This outlier control lottery table includes three modes of “out of 1”, “out of 2”, and “out of 3”, which have different modes of reel stop control. Outage 1 performs stop control that can shift the stop position up to four symbols from the timing at which the reel stop signal is received so that the symbol red 7 stops on the left reel 40L. Similarly, for the other central reel 40C and right reel 40R, stop control that can shift the stop position up to four symbols from the timing at which the reel stop signal is received so that the symbol bell stops. To do.

  Outage 2 is to perform stop control that can shift the stop position up to four symbols from the timing at which the reel stop signal is received so that the symbol blue 7 stops on the left reel 40L. Similarly, for the other central reel 40C and right reel 40R, stop control that can shift the stop position up to four symbols from the timing at which the reel stop signal is received so that the symbol bell stops. To do.

  The miss 3 performs stop control in which the stop position can be shifted up to four symbols from the timing at which the reel stop signal is received so that the symbol BAR stops on the left reel 40L. Similarly, for the other central reel 40C and right reel 40R, stop control that can shift the stop position up to four symbols from the timing at which the reel stop signal is received so that the symbol bell stops. To do.

  As described later, in the RT operation state, when the red 7, blue 7, or BAR stops on the left reel 40L and the bell stops on the center and right reels 40C and R, the value of NRT is set to 0 (see FIG. 16 step S204), the RT operation state is set to be released. As shown in FIG. 22, in this embodiment, the probability that the deviation 1, the deviation 2, and the deviation 3 are selected in the control lottery process in step S164 is set to 1/3, respectively, in the RT operation state. When the result of the winning lottery process is out of order, any one of out of 1, out of 2 and out of 3 is selected by the control lottery process.

  Moreover, the symbol arrangement of the reel of this embodiment is shown in FIG. In FIG. 24, the symbols of the reels other than the left reel are not described, and the symbols other than the symbols red 7, blue 7, and BAR are not described for the left reel. As is apparent from FIG. 24, in this symbol arrangement, if stop control is performed to shift the stop position to a maximum of four symbols on the left reel, any one symbol of red 7, blue 7, and BAR is displayed. It is possible to stop within the display frame.

  Therefore, if the result of the winning lottery is out of play in the RT operation state, if the player has not obtained any information regarding the symbols corresponding to the outage 1 to outage 3, it is determined with a relatively high probability. May stop and the RT operating state may be released. On the other hand, as shown in a notification image control subroutine (see FIG. 17) to be described later, if the player obtains information on the predetermined symbol, the predetermined symbol is stopped by the reel stop operation. It is possible to avoid this and continue the RT operation state.

  Next, a determination is made as to whether or not the off 1 has been selected in the control lottery process in step S164 (step S165). If it is determined by this determination that the disconnect 1 has been selected (YES), 1 is input as the value of HAZURE (step S166). Here, HAZURE is a parameter for performing reel stop control in accordance with the result of the control lottery process.

  If it is determined in step S165 that the disconnect 1 is not selected (NO), it is then determined whether the disconnect 2 is selected (step S167). In this determination, if it is determined that the loss 2 is selected (YES), 2 is input to the value of HAZURE (step S168).

  If it is determined in step S167 that the loss 2 is not selected (NO), in this embodiment, it is determined that the loss 3 is selected, and 3 is input as the value of HAZURE (step S169). .

  The HAZURE value is stored in the RAM 110 (step S170), and the HAZURE value is transmitted to the sub-control circuit 200 for use in a later-described notification image increase control subroutine (see FIG. 17) (step S171). Next, a value obtained by adding 1 to the NRT value is input as a new NRT value (step S172), and this subroutine is terminated.

  In the present embodiment, the process of increasing the value of NRT by 1 is performed only when the control lottery process is performed and one game out of 1 to 3 is performed. That is, the value of NRT is not only a parameter for determining whether or not it is in the RT operating state, but also a parameter indicating the number of games when one of the games 1 to 3 is performed in the RT operating state. . As shown in a notification image control subroutine (see FIG. 17), which will be described later, the value of this NRT is transmitted to the sub-control means 200. The notification image which notifies the symbol corresponding to 3 is displayed. Accordingly, it can be said that NRT represents the number of games for notifying the notification image. When the value of NRT exceeds the number NRTMAX determined in the notification number lottery process, processing for stopping the display of the notification image is performed.

  Also, as shown in the flowchart of FIG. 8, when NO is determined in steps S161 and S162, a route to the downstream side of step S172 is shown, but the destination is changed to the upstream side of step S172. It is also possible. In this case, regardless of whether or not the control lottery process is performed, a process of increasing the value of NRT by 1 for all games in the RT operating state is performed. Therefore, in this case, after the game state is changed to the RT operation state, when the number of games NRT exceeds the value of NRTMAX, processing for stopping the display of the notification image is performed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the control lottery processing subroutine (step S18) is completed, a reel fluctuation and stop subroutine (step S19) is performed. A detailed description of the reel fluctuation / stop subroutine will be given using the flowchart shown in FIG.

  First, the symbol number and control symbol data stored in step S49 of FIG. 7 are read (step S61). Then, it is determined whether or not a predetermined shortest time has elapsed (step S62). If it is determined that the shortest time has not elapsed (NO), the determination process of step S62 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 that the shortest time has elapsed (YES), a reel rotation start signal is transmitted (step S63). Based on this signal, the motor drive circuit 114 operates to start the rotation of the motors 80L, 80C, 80R, and the reels 40L, 40C, 40R start to rotate.

  Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S64). If it is determined that the reel has not yet rotated at a constant speed (NO), the determination process in step S64 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 that the reel rotates at a constant speed (YES), it is next determined whether or not a reel stop signal has been received (step S65).

  The reel stop signal is transmitted when the player pushes any one of the stop switches 52L, 52C, 52R. For example, when the stop switch 52L for the first reel is pushed, stop control of the motor 40L that rotates the first reel 40L is performed. Similarly, when the stop switch 52C for the second reel is pushed, the stop control of the motor 40C for rotating the second reel 40C is performed, and the stop switch 52R for the third reel is pushed. In such a case, stop control of the motor 40R that rotates the third reel 40R is performed.

  If it is determined that a reel stop signal has been received (YES), a symbol stop control subroutine is performed (step S66). The symbol stop control subroutine will be described later with reference to the flowchart shown in FIG.

  If it is determined in step S65 that the reel stop signal has not been received (NO), the control proceeds to step S67 without performing control related to the stop. In step S67, it is determined whether all reels have stopped. If it is determined that all reels are stopped (YES), this subroutine is terminated.

  If it is determined that all reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S68). If it is determined that the time limit has not been reached (NO), the process returns to step S65 again, and the processing from step S65 to step S68 is repeated. Thus, until all the reels stop or until the time limit elapses, the process of executing the corresponding reel symbol stop control subroutine is repeated each time the reel stop signal is received.

  If it is determined in step S68 that the time limit has passed (YES), a symbol stop control subroutine is performed on the reels that are still rotating to stop all reels (step S69). Thus, the reel fluctuation / stop subroutine ends.

<Design stop control subroutine>
Next, the symbol stop control subroutine shown in steps S66 and S69 of FIG. 9 will be described using the flowchart shown in FIG.
In this subroutine, first, it is determined whether or not the result of the winning lottery is off (step S181). If it is not out of date (NO), that is, if it is determined that any winning combination or re-playing combination is won, the process proceeds to symbol combination control (step S183). If it is determined that the result of the lottery is out of place (YES), it is next determined whether or not the value of NRT is greater than 0 (step S182). If it is determined in this determination that the value of NRT is 0 or less (NO), the process proceeds to symbol combination control (step S183). That is, in the present embodiment, when a winning combination or re-playing combination is won in the combination lottery, or when the NRT value is 0 or less and the RT operation state is not established, the symbol combination control (step S183) is performed. In the symbol combination control, it is possible to shift the stop position from the timing of receiving the reel stop signal to a maximum of four symbols, and the reel stop control so that the symbols corresponding to the winning combination in the winning lottery are aligned. Can be performed. This symbol combination control includes all reel stop controls except for the stop control corresponding to the miss 1, the miss 2, and the miss 3 shown in step S184 and the subsequent steps. Detailed description of the control process is omitted.

  If it is determined in step S182 that NRT is greater than 0 (YES), that is, if the result of winning lottery is off in the RT operating state, whether the stored HAZURE value is 1 or not? Is determined (step S184). In this determination, if it is determined that the value of HAZURE is 1 (YES), a reel stop signal is received so that the symbol red 7 stops on the left reel and the symbol bell stops on the center and right reels. From the timing, stop control capable of shifting the stop position (sliding up to 4 frames) up to a maximum of 4 symbols is performed (step S185). If the predetermined symbol (red 7 and bell) does not stop even if the maximum four frames are stopped, the RT operation state is not canceled (see step S203 in FIG. 16). The conditions are not carried over to subsequent games. After performing the above processing, this subroutine is terminated.

  If it is determined in step S184 that the value of HAZURE is not 1 (NO), it is next determined whether or not the value of HAZURE is 2 (step S186). If it is determined in this determination that the value of HAZURE is 2 (YES), a reel stop signal is received so that symbol blue 7 stops on the left reel and symbol bell stops on the center and right reels. From the timing, stop control is performed that can shift the stop position up to four symbols (slide up to four frames) (step S187). If the predetermined design (blue 7 and bell) does not stop even if the stop control of sliding up to 4 frames is performed, the RT operation state is not released (see step S206 in FIG. 16). The conditions are not carried over to subsequent games. After performing the above processing, this subroutine is terminated.

  If it is determined in step S186 that the value of HAZURE is not 2 (NO), in this embodiment, the value of HAZURE is determined to be 3, and the symbol BAR is stopped on the left reel, Stop control is performed so that the stop position can be shifted to a maximum of four symbols from the timing at which the reel stop signal is received so that the symbol bell stops on the right reel (maximum four frames are slid) (step S188). If the predetermined symbol (BAR and bell) does not stop even if the stop control of sliding up to 4 frames is performed, the RT operation state is not released (see step S207 in FIG. 16). However, it is not carried over to the game played after that. After performing the above processing, this subroutine is terminated.

  In addition, regarding the central reel and the right reel, it is possible to always set the bell to stop by the stop control of sliding up to four frames by arranging the symbol bell within 4 frames.

<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 of the flag off / RT setting processing subroutine shown in FIG.

  First, it is determined whether or not the game state is RB game (step S81). If it is determined that the RB game is being played (YES), an RB game processing subroutine (step S82) 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 S81 that the game state is not RB game (NO), it is next determined whether or not the game state is BB game (step S83). If it is determined that the BB game is in progress (YES), a BB game in-process subroutine (step S84) 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 S83 that the game state is not BB game (NO), it is next determined whether or not there is a winning combination (step S85). If it is determined that there is a winning combination (YES), a winning combination processing subroutine (step S86) 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 S85 that there is no winning combination (NO), a general processing subroutine (step S87) 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 S82, S84, S86, and S87 will be given.

<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S82) executed when it is determined in step 81 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 that the BB game is being played (YES), that is, the RB game is being played during the BB 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). If it is determined that the BB game end condition has been achieved (YES), the BB game state is canceled (step S106).

  Then, 1 is input as the value of NRT (step S107), and this subroutine is terminated. By inputting 1 to the NRT, from the next game, the gaming state is changed to the RT operating state (see step S35 in FIG. 6), and until the RT operating state is released (step S42 in FIG. 7, FIG. 15). The game can be performed in the RT operation state (see step S157).

  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 S108). If it is determined that the RB end condition is achieved (YES), the RB gaming state is canceled (step S109), and then the process proceeds to step S110. If it is determined that the RB end condition is not achieved (NO), the RB gaming state is not released and the process proceeds to step S110. In step S110, 0 is input as the value of NRT, and this subroutine is terminated. Here, since the BB game is continued, the process of changing the gaming state to the RT operating state is not performed even when the RB ends.

  Next, returning to the determination in step S103, when 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). If it is determined that the RB end condition is not achieved (NO), 0 is input as the value of NRT (step S112), and this subroutine is ended. Here, since the RB game is continued, the process of changing the gaming state to the RT operating state is not performed.

  If it is determined in step S111 that the RB end condition is achieved (YES), the RB gaming state is canceled (step S113), and 1 is input as the value of NRT (step S107). Unlike the case of step S110, since BB game is not performed, in the case of RB end, the process which changes a game state to RT operation state is performed. After performing the above processing, this subroutine is terminated.

<Description of processing subroutine during BB game>
Next, FIG. 13 shows a detailed explanation of the BB game processing subroutine (see step S84) executed when it is determined that the BB game is being played in step S83 in the flag off / RT setting processing subroutine (see FIG. 11). 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, the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110 (step S122). 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 S123). If it is determined that the BB game end condition is achieved (YES), the BB game state is canceled (step S124), and 1 is input as the value of NRT (step S125). That is, since the BB game is finished, a process for changing the gaming state to the RT operating state is performed. Then, this subroutine ends.

  Note that it is determined in step S81 of the flag off / RT setting processing subroutine (see FIG. 11) that it is not already in the RB game, and therefore it is not necessary to consider the RB game in this subroutine.

  If it is determined in step S123 that the BB termination condition is not achieved (NO), 0 is input as the value of NRT (step S126). Here, since the BB game is continued, the process of changing the gaming state to the RT operating state is not performed. Then, this subroutine ends.

<Explanation of the processing sub-routine at the time of winning>
Next, in the flag off / RT setting processing subroutine (see FIG. 11), the detailed explanation of the winning combination processing subroutine (see step S86) executed when it is determined that there is a winning combination in step S85 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 S131). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S132).

  If it is determined that the winning combination (YES) is made, it is next determined whether or not the BB combination or the RB combination has won (step S133). If it is determined that the BB and RB combination has won (YES), the winning BB and RB flags are turned off, and instead, the winning gaming state is set (step S134), and this subroutine is terminated. By setting the winning game state, the BB and RB games are started from the next game. For example, in the determination in step S81 and step 83 in FIG. 11, it is determined that the BB and RB games are in progress.

  If it is determined in step S133 that the BB combination or RB combination has not won (NO), it is next determined whether or not the re-game combination has won (step S135). If it is determined that the re-game player has won (YES), the process proceeds to step S136, the re-game flag is turned off, and the re-game state is set instead. If the BB and RB flags are on, carry-over processing of the BB and RB flags is performed, and this subroutine is terminated.

  If it is determined in step S135 that the re-gamer has not won a prize (NO), the process proceeds to step S137, the general winning prize processing subroutine is performed, and this subroutine is terminated.

  Here, the general winning prize subroutine will be described in detail with reference to the flowchart shown in FIG. First, it is determined whether or not a general combination is won from the symbols stopped by the reel fluctuation and stop subroutine described above (step S151). If it is determined in this determination that the general combination is won (YES), the general combination flag is turned off (step S152). If it is determined in step 151 that the general combination has not been won (NO), the process proceeds to step 153 without performing the flag-off process.

  In step S153, it is determined whether the BB flag or the RB flag is on. If it is determined in this determination that the BB flag or RB flag is on (YES), carry-over processing of the BB flag or RB flag is performed (step S154), and this subroutine is terminated. If it is determined in step S153 that neither the BB flag nor the RB flag is on (NO), the carry-over process is not performed and the present subroutine is terminated.

  Next, returning to the determination in step S132 of the winning combination subroutine of FIG. 14, 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 S138). If it is determined that the BB and RB flags are on (YES), carry-over processing of the BB and RB flags is performed, and if the other flags (re-playing combination, general combination) are on, The flag is turned off (step S139), and this subroutine is terminated.

  If it is determined in step S138 that the BB and RB flags are not turned on (NO), the flag turned on (re-playing game, general game) is turned off (step S140). Exit the subroutine.

<Description of general processing subroutine>
Next, FIG. 16 shows a detailed description of the general processing subroutine (see step S87) executed when it is determined that there is no winning combination (NO) in step S85 in the flag off / RT setting processing subroutine (see FIG. 11). This will be described with reference to the flowchart shown.

  First, it is determined whether or not the value of NRT is greater than 0 (step S201). If it is determined by this determination that the value of NRT is 0 or less (NO), this subroutine is terminated as it is. In this determination, if it is determined that the value of NRT is greater than 0 (YES), that is, it is determined that the RT operation state and the result is out of the winning lottery process (see step S85 in FIG. 11). If so, it is next determined whether or not the value of HAZURE is 1 (step S202).

  In this determination, if it is determined that the value of HAZURE is 1 (YES), it is next determined whether or not the symbol red 7 is stopped on the left reel and the symbol bell is stopped on the center and right reels. (Step S203). If it is determined by this determination that the predetermined symbol (red 7, bell) has stopped (YES), 0 is input as the value of NRT (S204), and this subroutine is terminated. If it is determined in step S203 that the predetermined symbol (red 7, bell) is not stopped (NO), the present subroutine is terminated.

  If it is determined in step S202 that the value of HAZURE is not 1 (NO), it is next determined whether or not the value of HAZURE is 2 (step S205). If it is determined in this determination that the value of HAZURE is 2 (YES), it is next determined whether or not the symbol blue 7 stops on the left reel and the symbol bell stops on the center and right reels. (Step S206). If it is determined in this determination that the predetermined symbol (blue 7, bell) has stopped (YES), 0 is input as the value of NRT (step S204), and this subroutine is terminated. If it is determined in step S206 that the predetermined symbol (blue 7, bell) is not stopped (NO), this subroutine is terminated as it is.

If it is determined in step S205 that the value of HAZURE is not 2 (NO), in this embodiment, it is determined that the value of HAZURE is 3, and then the symbol BAR is stopped on the left reel, It is determined whether or not the symbol bell stops at the center and right reels (step S207). If it is determined by this determination that the predetermined symbol (BAR, bell) has stopped (YES), 0 is input as the value of NRT (S204), and this subroutine is terminated. If it is determined in step S207 that the predetermined symbol (BAR, bell) is not stopped (NO), this subroutine is terminated as it is.
Here, when 0 is input as the value of NRT in the process of step S204, the game is played in a state where the RT operation state is released from the next game.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S82, S84, S86, and S87 ends, and the flag-off and RT setting processing subroutine shown in FIG. 11 ends. Here, returning to the main routine of FIG. 5, the flag-off and RT setting process subroutine of step S20 is terminated, the payout process of step S21 is terminated, 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.

<Notification image control subroutine>
Next, the notification image control subroutine performed by the image display means 510 of the sub control circuit circuit 200 will be described with reference to the flowchart shown in FIG. In this subroutine, when a predetermined requirement is satisfied, control is performed to display a notification image for notifying the player of symbols corresponding to the deviation 1 to the deviation 3 only while the reel is rotating.

  First, based on the data received from the main control circuit 100, it is determined whether or not the result of the role lottery process is out of order (step S301). If it is determined by this determination that it is not out of place (NO), this subroutine is terminated as it is.

  If it is determined in step S301 that the result of the lottery process is out of place (YES), it is next determined whether or not the value of NRT is greater than 0 (step S302). If it is determined that the value of NRT is 0 or less (NO), this subroutine is terminated as it is. If it is determined in step S302 that the value of NRT is greater than 0 (YES), that is, if the winning lottery result is off in the RT operating state, whether or not the value of NRT is 1 next is determined. Is determined (step S303).

  In this determination, if it is determined that the value of NRT is 1 (YES), this is a game in which a notification image is displayed first after the start of the RT operation state. The number of games played) is determined. In this process, first, a notification frequency lottery table is read (step S304). Here, FIG. 23 shows an example of the notification frequency lottery table. In this notification frequency lottery table, there are eight types of values of notification frequency: 1, 3, 5, 10, 20, 100, 1000, 2000. The probability that these values are selected in the notification number lottery process is set such that the probability of 1 / 6.4 is set for each of the six types of values 1 to 100, and the value of 1000 is 1 / 21.3. A probability is set, and a probability of 1/64 is set to a value of 2000. Therefore, the possibility that a large value such as 1000 or 2000 is selected as the number of notifications is low.

  Next, a control lottery process for obtaining a random number and making a lottery determination is performed (step S305). Specifically, in the notification number lottery means 540, the random number generated by the random number generator is extracted by the random number extractor, and the random number determination means compares the extracted random number with the read lottery table as described above. Make a decision to determine the value. The selected number of notifications is input as the value of NRTMAX (step S306), and the process proceeds to step S307.

  If it is determined in step S303 that the value of NRT is not 1 (NO), that is, it is not the game that displays the notification image for the first time, the notification number lottery process is not performed and the process proceeds to step S307.

  In step S307, it is determined whether or not the value of NRT is larger than NRTMAX to which the value is input in step S306. When it is determined that the value of NRT is larger than NRTMAX (YES), this subroutine is finished as it is. That is, when the value of NRT exceeds the number of notifications NRTMAX, the notification image is set not to be notified thereafter. If it is determined in step S307 that the NRT value is less than or equal to the number of notifications NRTMAX (NO), among the notification image data stored in the ROM 208, image data corresponding to the values 1 to 3 of the parameter HAZURE. Is read (step S308).

  Next, it is determined whether or not the reel has started rotating (step S309). If it is determined that the reel has not started rotating (NO), the same control loop is repeated. If it is determined that the rotation of the reel has been started (YES), the notification image data read in step S308 is transmitted to the display driving device 220, and the notification image is displayed on the display device 70 (step S310). ). With this notification image, the player can recognize the symbol red 7 when the deviation 1 is selected by the control lottery process, and can recognize the blue 7 when the deviation 2 is selected. Yes, when the off-set 3 is selected, the symbol BAR can be recognized. It is also possible to notify the symbol bell with a notification image. As the content of the notification notification image, it is possible to notify the symbol directly or implicitly to notify the symbol, for example, using light, color, symbol, character image It is also possible to do. It can also be combined with voice.

  Next, it is determined whether or not all the reels are stopped (step S311). If it is determined that all reels are not stopped (NO), the same control loop is repeated. That is, the notification image continues to be displayed while one reel is rotating.

  When it is determined that all reels are stopped (YES), an image erasure signal is transmitted to the display drive device 220 to erase the notification image displayed on the display device 70 (step S312). Exit the subroutine.

  As described above, in this subroutine, for example, when the disparity 1 is selected by the control lottery process and the notification image indicating the symbol red 7 is displayed, the symbol red 7 is stopped on the left reel by the reel stop operation. Can be avoided, so that the RT operating state can be continued. Therefore, it can be expected that the player feels the fun of the game and raises interest in the game.

(Other embodiments)
In the above-described embodiment, the case where a predetermined symbol is stopped in the left reel is described as an embodiment for releasing the RT operation state. However, the same setting can be performed on any reel, and all reels can be set. It is also possible to set so that a predetermined symbol stops. As for the reel stop control, not only the stop control for shifting the stop position to a maximum of four symbols from the timing at which the reel stop signal is received, but also any other stop control can be performed.

  In addition, as an embodiment for canceling the RT operation state, the RT operation state may be canceled when a winning combination such as RB or BB is won in the role lottery process or when a predetermined symbol is stopped. Although shown, the present invention is not limited to this, and when any other combination including a general combination is won, or when the selected combination wins, it is possible to control to release the RT operation state. Various other requirements can also be set.

  Similarly, it is indicated that the RB and BB games are ended as the start condition of the RT operation state. For example, there may be a case where the game is performed a predetermined number of times after the RB and BB games are ended. Various other requirements can be set.

In the above-described embodiment, the display of the notification image is set to be stopped after the number of games for displaying the notification image exceeds a predetermined number. For example, after the RT operation state is started, It is also possible to set so that the display of the notification image is stopped after the number of all games played exceeds a predetermined number.
