Description

  The present invention relates to a slot machine that rotates a reel on which a plurality of symbols are displayed based on a player's operation, stops the game, and determines a game result by a combination of symbols at the time of stop, and particularly relates to a player's operation. The present invention relates to a slot machine that displays effect images.

  A slot machine that determines a game result by a combination of symbols at the time of stoppage when a player inserts a game medium, rotates a plurality of reels on which symbols are displayed based on the player's operation, and stops the game. It is widely used as one of these. This slot machine is usually provided with operation means including a start switch and a stop switch. When the player operates the start switch, the reels are controlled to rotate, and when the player operates the stop switch, Control is performed to stop the reel corresponding to the stop switch. Also, a slot machine is widely used in which an effect image is displayed on a display device together with a game in which a reel is rotated to stop, thereby increasing the player's interest in the game.

In such a slot machine, if the effect image is displayed regardless of the player's operation, the game's preference is lacking. Therefore, the player's operation is related to the effect image to be displayed, and the game's preference is displayed. Slot machines have been proposed that aim to increase (For example, refer to Patent Document 1.)
JP 2001-120715 A

  The slot machine proposed in Patent Document 1 is set to display a new effect image every time the stop switch is operated. However, when the stop switch is operated during the display of the scheduled effect image, the display of the scheduled effect image is interrupted and the next effect image is displayed. In this case, if the player operates each stop switch at short intervals, the game ends before the content of the effect image is transmitted to the player, and the player's operation and the effect image are related to each other. However, as the game continues, the player's interest in the game may decrease.

  Therefore, the object of the present invention is to solve the above-mentioned problem, and even if the player operates each stop switch at a short interval, the player can fully enjoy the displayed effect image and further display the displayed image. It is an object of the present invention to provide a slot machine that can change the effect image and increase the interest of the player in the game and can sustain it.

  In order to achieve the above object, as a slot machine according to the present invention, a slot machine capable of performing a game in which a process for rotating and stopping a plurality of reels displaying a plurality of symbols is performed once. A reel control means for performing a stop control of the reel corresponding to the reel stop signal among the plurality of rotated reels when receiving a reel stop signal transmitted based on a player's stop operation; Image display means for controlling the display of the effect image, and the image display means is operated by the player before a predetermined percentage of the effect image scheduled to be displayed during one game is displayed. When all the reels are stopped and the game is finished, control is performed to display the remaining effect images that are not displayed in the next game, and when the predetermined requirement is satisfied in the next game, the display is performed. That effect images, it is conceivable that can be controlled to change from the rest of the effect image that was not the display to another effect image.

  Here, 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 is displayed on the image that is rotated and stopped. Is also included.

  The “reel stop signal” is a signal transmitted by the reel operation means when the player operates the reel stop switch. The “reel control means” is control means for controlling the reels when a reel operation signal transmitted from the reel operation means is received. Specifically, when the start switch ON signal transmitted by the reel operation means is received, the reel is controlled to start rotating, and when the reel stop signal transmitted by the reel operation means is received, the rotation is performed. The stop control of the reel being performed is performed. In this case, it is possible to set the rotation of all reels to start based on the operation of one start switch, and it corresponds to the start switch operated based on the operation of the start switch corresponding to each reel. It is also possible to set the reel to rotate. Similarly, it is possible to set the rotation of all reels to stop based on the operation of one stop switch, and it corresponds to the operated stop switch based on the operation of the stop switch corresponding to each reel. It is also possible to set the reel to stop. A detailed description of the reel stop control will be given later.

  The “image display unit” includes, for example, a display device that displays an image, an image drive circuit, and an image control unit that performs control for image display, and controls display of a predetermined effect image. Specifically, the image control means reads out predetermined image data stored in the storage area of the control circuit and transmits it to the image drive circuit, and the image drive circuit displays an effect image based on the transmitted image data, Display on the display device.

  The “effect image” includes any image as long as it is displayed on the display device. For example, any image such as a character, a pattern, a color, and a pattern can be applied, and a still image and a moving image are also included. . It can also be combined with voice.

  Further, the “predetermined ratio” of the effect images scheduled to be displayed during one game may be, for example, a ratio with respect to the total display time of effects scheduled to be displayed during one game. It may be a ratio to the total number of cuts of the effect image scheduled to be displayed, or a ratio to all other matters can be set. In the case of using the total display time, the determination as to whether or not the predetermined percentage of the effect images scheduled to be displayed during one game is reached is based on the total display time of the effect images scheduled to be displayed during one game. On the other hand, it is conceivable to determine whether or not a predetermined display time has been reached. When using the total number of cuts, it is determined whether or not the predetermined number of displayed cuts has been reached with respect to the total number of cuts. It is possible to do.

  In addition, the “predetermined requirements” in the next game may be, for example, a case where a predetermined combination is won by a lottery, or a case where a predetermined combination wins as a result of a reel stop operation In addition, a case where a predetermined item is selected by performing a lottery process can be considered, and all other requirements can be set.

  In the slot machine of the present invention, the game can be started by inserting a game medium, and a predetermined number of game media can be paid out according to the result of the game. Here, the game medium is a medium inserted into the slot machine for playing a game, and for example, a coin, a medal, or a chip 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, etc., and storing it in a storage medium of the slot machine. This includes using a predetermined number of game media credited in advance.

  In this embodiment, if the player performs a reel stop operation at short intervals and all the effect images scheduled to be displayed during one game are sufficiently displayed, all the reels are stopped and the game is stopped. Even if the game is over, the player can fully enjoy the effect image by displaying the remaining effect image in the next game. Furthermore, when a predetermined requirement is satisfied in the next game, it is possible to change the effect image to be displayed from the remaining effect image to another effect image. Since it is possible to feel sex, it can be expected that the player's interest in the game will be increased and sustained.

  The slot machine according to the present invention further includes a determination criterion for determining whether or not the effect image to be displayed includes a plurality of effect images and the remaining effect image that has not been displayed is displayed in the next game. It is conceivable that the predetermined ratio can be set for each effect image.

  In the present embodiment, a predetermined ratio that is a determination criterion for determining whether or not to display the remaining effect images that are not displayed in the next game can be set differently for each effect image. Therefore, it is possible to change the progress of the effect image, and it is expected that the player's interest in the game is enhanced and sustained.

  In the slot machine according to the present invention, when displaying the remaining effect images that are not displayed in the next game, one of the plurality of display effect image candidates including the remaining effect images that are not displayed is displayed. When the selected one effect image is different from the remaining effect image that has not been displayed, the effect image to be displayed is the remaining effect image that has not been displayed. Therefore, it is conceivable to perform control to change to the selected one effect image which is another effect image.

  In this embodiment, as a method for selecting one effect image from a plurality of display effect image candidates, for example, one effect image can be selected by lottery, or one effect image can be selected based on the player's operation. Images can be selected and any other selection method can be used. In the present embodiment, depending on the selection result, there are cases where the remaining effect image is displayed as it is and cases where the display image is changed to a different effect image, so that the progress of the effect image is changed and the game is continued for a long time. However, it can be expected that the player's interest in the game will be sustained.

  As a slot machine according to the present invention, a role lottery means for performing a lottery for determining at least one role by lottery from among a combination including a winning combination, and a winning flag when the winning combination is won by the lottery When it is determined that the symbol corresponding to the winning combination has not stopped and won in the internal medium state in which the winning flag is set, until the symbol corresponding to the winning combination stops and wins And a winning flag control means for performing control to carry over the internal medium state to the next game, and an effect image that is highly likely to be selected when the winning flag is not set in the plurality of effect images And other effect images that are likely to be selected when the hit flag is set.

  Here, “winning game” means “winning game” in which when a winning game is won by lottery and a game corresponding to the winning game stops and wins, the game proceeds in a manner advantageous to the player. It is a role that can be performed. The winning combination includes a big bonus combination (hereinafter referred to as BB combination) and a regular bonus combination (hereinafter referred to as RB combination), and other arbitrary winning games can be set.

  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.

  In addition, the “combination” includes not only the above winning combination, but also a general combination that pays out a predetermined number of game media when winning, or “re-game” that allows a game to be re-executed without inserting a game media. For example, a “re-game” can be set.

  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-playing” means that when a re-playing role is won by lottery and the symbol corresponding to the re-playing role stops and wins, the next game can be executed without throwing in game media. (Also called replay).

  In the “lottery” for determining at least 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. In addition, “determining at least one combination” means that one combination may be determined from among a plurality of combinations by lottery. For example, a winning combination and a general combination will be won simultaneously by lottery. It means that two or more roles may be determined at the same time.

  In addition, “corresponding symbol combinations stop” means, for example, that symbols determined corresponding to roles for each reel are stopped on a predetermined effective line and predetermined symbols are aligned. means. In this case, a case where a symbol to be stopped is defined for all reels is included, and a case where a symbol to be stopped for some reels is also included. The symbols to be stopped can be set to the same symbol for all reels, or different symbols can be set for each reel.

  “The corresponding symbol combination does not stop” means that the requirement for corresponding to the “corresponding symbol combination stops” is not satisfied. Therefore, for example, even when the symbols to be stopped on some of the required reels do not stop, “does not stop”. Of course, even when the symbols to be stopped on all the required reels do not stop, it does not stop.

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

  In the present embodiment, among the plurality of effect images, an effect image that is highly likely to be selected when the hit flag is not set, and an effect that is highly likely to be selected when the hit flag is set. Since there is an image, for example, when the first game is performed with no hit flag set, and in the second game, if the winning combination is won in the lottery, the selection is made in the first game Because the effect image that is easily played is different from the effect image that is easily selected in the second game, there is a high possibility that different effects will be displayed in the first game and the second game. In particular, in the case of displaying the remaining effect image that was not displayed in the second game, the display image may be changed from the remaining effect image to another effect image during the second game. Since it becomes higher, it can be expected that the player's interest in the effect image is increased, and in turn, the player's interest in the game can be increased.

  The slot machine according to the present invention further includes a plurality of cuts in which the plurality of effect images are sequentially displayed, and the progress of the effects corresponds to each other with respect to the cuts corresponding to the display order of the plurality of effect images. It is conceivable that the content has

  In this embodiment, since the effect image is composed of a plurality of cuts, an effect image with less sense of incongruity is displayed when the remaining effect image is displayed in the next game, no matter what timing the game ends. Can be displayed. Even if the effect image is changed, the progress situation for each cut corresponds, so that it is always possible to display an effect image with little discomfort. Therefore, it is possible to increase the player's interest in the effect image, and in turn, increase the player's interest in the game.

  As the slot machine according to the present invention, the cut further includes a cut that can be controlled to change the display image from the remaining effect image that has not been displayed to another effect image, and an impossible cut. May be included.

  Depending on the progress of the production, there is a cut that is not appropriate to change to another production image. Therefore, as in this embodiment, having a cut that can be changed to another effect image and a cut that is impossible, the progress of the effect can be progressed smoothly, and the player is interested in the effect image. It can be expected to increase the interest of the player in the game.

  According to the above-described invention, all the reels are stopped before the player performs a reel stop operation at a short interval and the effect image scheduled to be displayed during one game is sufficiently displayed. Even when the game ends, the player can fully enjoy the effect image by displaying the remaining effect image in the next game. Furthermore, when a predetermined requirement is satisfied in the next game, it is possible to change the effect image to be displayed from the remaining effect image to another effect image. Since it is possible to feel sex, it can be expected that the player's interest in the game will be increased and sustained.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The random number generator generates a random number included in a certain range of numerical values, for example, 0 to 65535 (2 to the 16th power). Note that a random number may be generated by the arithmetic processing of the CPU 206.

  A lamp driving circuit 218 for driving the effective line display lamp 124 is also connected to the input / output bus 204. The CPU 206 issues a drive command to the lamp drive circuit 218 in accordance with the control information supplied from the main control circuit 100, and turns on the active line display lamp 124 in response to the drive command.

  In addition, a display drive circuit 220 that drives the display device 70 is also connected to the input / output bus 204. The CPU 206 reads image data, character data, and the like stored in the ROM 208 in accordance with control information supplied from the main control circuit 100 and supplies the data to the display drive circuit 220. By doing so, the display device 70 displays image data as an effect image or character data as a message.

  Further, a speaker drive circuit 222 for driving the speaker 64 is also connected to the input / output bus 204. The CPU 206 reads out audio data stored in the ROM 208 in accordance with control information supplied from the main control circuit 100 and supplies the data to the speaker drive circuit 222. By doing so, a predetermined sound is emitted from the speaker 64.

And reel operation for stopping the reels 40L, 40C, 40R when a reel stop signal transmitted from the operation means 300 is received based on the operation of the stop switches 52L, 52C, 52R or when a predetermined time elapses. Take control. In the stop control, the symbol combination control is performed so that the stop symbols are aligned corresponding to the winning combination. The control processing by the reel control means 440 is shown in the reel fluctuation / stop subroutine (see FIG. 8).

  The winning flag control means 450 stores the winning flag in the RAM 110 of the main control circuit 100 when the winning combination is won in the winning lottery, performs control processing for setting the winning flag, and determines the winning symbol related to the stopped symbol, When it is determined that the symbol corresponding to the winning winning combination is not stopped, the control process for continuing the set winning flag to the next game is performed, and it is determined that the symbol corresponding to the winning winning combination is stopped. In some cases, a control process for canceling the set hit flag is performed.

  The winning game control means 460 is advantageous to the player when it is determined that the symbol corresponding to each role has stopped by the winning symbol determination regarding the symbol that has been won by the winning combination or the general role in the winning lottery. Payout of a game or a predetermined number of game media that progresses to Further, when the re-game control means 470 determines that the symbols corresponding to the re-game players have been prepared by the winning symbol determination regarding the symbols that have been re-winned in the role lottery and stopped, the next game control means 470 does not insert the game medium. The control process for performing the re-game where the game can be performed is performed.

<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 RB and BB flags are on, that is, whether or not the inside is inside (step S11). If it is determined in this determination that the RB and BB flags are on (YES), then a flag on signal is transmitted to the sub-control circuit 200 (step S12), and the process proceeds to step S13. The flag-on signal transmitted in step S12 is used for the determination process in step S206 of the effect image display subroutine (see FIG. 13). If it is determined in step S11 that the RB and BB flags are not on (NO), the process proceeds to step S13 as it is.

  In step S13, it is determined whether or not the value of the parameter NRP is greater than 0 (step S13). Here, NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is greater than 0, and replay is not performed when it is 0 or less. Further, as shown in step S167 of FIG. 12, when the re-gamer is won and won, 1 is input as the value of NRP.

  If it is determined in step 13 that the value of NRP is 0 or less (NO), it is determined that no re-game is performed, and then it is determined whether or not a game medium is inserted (step). S14). If it is determined in this determination that a game medium has been inserted (YES), the process proceeds to step S17, 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 S14 that no game medium is inserted (NO), the process proceeds to step S15 to determine whether there is a credited game medium (step S15). If it is determined by this determination that there is no credited game medium (NO), the process returns to step S14 again, and the determination processes of steps S14 and S15 are repeatedly executed.

  If it is determined in step S15 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S16). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34 and 36. When it is determined that the bet operation signal has not been received (NO), the process returns to step S14 again, and the determination process from step S14 to step S16 is repeatedly executed. If it is determined in step S16 that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S17). 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 S18). The game start state is now complete, and the process proceeds to step S20.

  If it is determined in step S13 that the NRP value is greater than 0 and the game is in the replaying state (YES), 0 is input to the NRP value to cancel the replaying state (step S19), and step S14. From step S18, the same bet number as the bet number in the previous game is set without proceeding to step S18, and the process proceeds to step S20. That is, when it is determined that the game is in the re-gaming state, the game can be performed without newly inserting a game medium or consuming the credited game medium. In this embodiment, the bet number in the replay is set to the same bet number as in the previous game, but it is also possible to set a bet number different from the bet number in the previous game. .

  In step S20, a game start signal is transmitted to the sub-control circuit 200, and the process proceeds to step S21. The game start signal transmitted in step S20 is used for the determination process in step S200 of the effect image display subroutine (see FIG. 13). Subsequent to step S20, a combination lottery processing subroutine is performed (step S21). In this combination lottery processing subroutine, combination lottery processing by the combination lottery means 410 is performed, and flag-on processing for turning on the 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 combination lottery processing subroutine (step S21), based on the result of the combination lottery, the reel fluctuation and stop subroutine (step S22) performs control processing related to the movement of the reels that are stopped after the reels 40L, 40C, and 40R are rotated. ) Is performed. This reel fluctuation / stop subroutine is performed by the reel control means 440, and details of this subroutine will be described later with reference to the flowchart of FIG.

  Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and a winning determination and flag off processing subroutine (step S23) for performing a flag-off process based on the determination result is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S24) 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 S21 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. This is performed (see step S63 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 the start switch ON signal has been received (YES), then a start operation signal is transmitted to the sub-control circuit 200 (step S32), and the process proceeds to step S33. The start operation signal transmitted in step S32 is used for the determination process in step S214 of the effect image display subroutine (see FIG. 13).

  Next, in step S33, 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 of FIG. 11 and step S164 of FIG. 12, 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 S38. 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. Also, as shown in step S164 of FIG. 12, 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 greater 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 S38. 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 a general lottery table when the BB is not operated (see FIG. 19), which will be described later, the general lottery table when the BB is operated is set to have no re-game combination and BB combination.

  If the winning combination in the lottery is 1/80 and the symbol on the right 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 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 replay symbols are aligned on the left and middle reels, and the bell symbol is aligned on the right reel. ing. In the BB non-operating general lottery table described later (see FIG. 19), 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), the BB non-operating general lottery table stored in the ROM 108 is read (step S37), and the process proceeds to 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 combinations of symbol numbers 1 to 3 have the same settings for the above-described general lottery table at the time of BB operation (see FIG. 18), and the winning probability and symbol settings in the combination lottery. 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.

  The RB role of symbol number 5 is set to win when the winning probability in the symbol lottery process is 1/600 and all three reels have the blue 7 symbol. The chance of winning a role is low. 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 the red 7 symbol. In addition, the probability in the extra lot drawing is set to about 1 / 1.57.

  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 S38). Specifically, the random number generated by the random number generator 112 is extracted by the random number extraction means 420, and the random number determination means 430 compares the extracted random number with the above-described lottery table that has been read to determine the winning.

  Subsequently to FIG. 6, the process proceeds to FIG. 7. As a result of the determination, it is determined whether or not the RB combination is won (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), and the process proceeds to step S44.

  If it is determined in step S40 that the RB combination has not been won (NO), it is next determined whether or not the BB combination has been won (step S42). If it is determined by this determination 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 S43), and the process proceeds to step S44. In step S44, RB and BB winning signals are transmitted to the sub-control circuit 200 (step S44), and the process proceeds to step S49. The RB and BB winning signals transmitted in step S44 are used for the determination process in step S224 of the effect image display subroutine (see FIG. 13).

  Returning to the determination of step S42, if it is determined 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 in this determination that the re-gamer has been won by the role 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 re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S47). In this determination, if it is determined that the general combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step 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. 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 S21) is completed, a reel fluctuation and stop subroutine (step S22) is then performed. Next, the reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.

  First, the symbol number and control symbol data stored in step 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 in this determination that the shortest time has not elapsed (NO), the determination process in 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 in step S62 that the shortest time has elapsed (YES), the start switch ON signal has already been received (see step S31 in FIG. 6). Transmission to the drive circuit 114 starts rotation of the motors 80L, 80C, 80R, and rotates the reels 40L, 40C, 40R (step S63).

  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 in this determination 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 in step S64 that the reel has been rotated at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S65). 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 S65 that the reel stop operation detection signal has been received (YES), the reel control means 440 controls the reel symbol combination control (stop control) corresponding to the stop switch that has transmitted the operation detection signal. ) (Step S66), the process proceeds to step S67.

  More specifically, when the stop switch 52L for the left reel is pushed, the reel control means 440 performs stop control in step S66 for the motor 80L that rotates the left reel 40L. Similarly, when the stop switch 52C for the middle reel is pushed, the stop control in step S66 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 S66 is performed for the motor 80R that rotates the right reel 40R.

  The symbol combination control (stop control) is based on the symbol number and control symbol data read in step S61, and the frame when the reel stop signal is received is the first frame, the reel is slid up to the fifth frame, and the range The motor stop control is performed so as to stop or not stop a predetermined symbol.

  Subsequent to step S66, a reel stop information signal is transmitted to the sub-control circuit 200 (step S67), and the process proceeds to step S68. The reel stop information signal transmitted in step S67 is used for the determination processing in steps S302, 306, and 310 of the next cut display subroutine (see FIG. 14). If it is determined in step S65 that the reel stop signal has not been received (NO), the control proceeds to step S68 without performing control related to the stop. In step S68, it is determined whether or not all reels have been stopped (step S68).

  If it is determined in this determination that all reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S69). If it is determined in this determination that the time limit has not been reached (NO), the process returns to step S65 again, and the processes from step S65 to step S69 are 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 S69 that the time limit has passed (YES), automatic symbol stop control is performed on the reels that are still rotating to stop all reels (step S70), and the process proceeds to step S71. move on. In this automatic symbol stop control, it is possible to shift the stop position of a maximum of five symbols (five frames) with the frame at the time limit elapse as the first frame, and the winning symbol is always within that range. Stop control is performed so that they are not aligned.

  Next, the process returns to the determination in step S68, and if it is determined that all the reels are stopped (YES), the process proceeds to step S71. In step S71, an all-reel stop signal is transmitted to the sub-control circuit 200 (step S71), and this subroutine is terminated. The all-reel stop signal transmitted in step S71 is used for the determination process in step S218 of the effect image display subroutine (see FIG. 13).

<Explanation of Winning Determination and Flag Off Processing Subroutine>
Next, in the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S22) is completed, a winning determination and flag-off process subroutine (step S23) is performed. The winning determination and flag off 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 that the value of NRB is greater than 0 (whether or not an RB game is being played) (step S91). If it is determined in this determination that the value of NRB is greater than 0 (YES), an RB game processing subroutine (step S92) is performed, and this subroutine is terminated. A detailed description of the RB game processing subroutine will be described later with reference to FIG.

  If it is determined in step S91 that the NRB value is 0 or less (NO), it is next determined whether or not the NBB value is greater than 0 (whether or not a BB game is being played). (Step S93). If it is determined in this determination that the NBB is (YES), a BB gaming process subroutine (step S94) is performed, and this subroutine is terminated. A detailed description of the BB game processing subroutine will be described later with reference to FIG.

  If it is determined in step S93 that the NBB value is 0 or less (NO), it is next determined whether or not there is a winning combination (step S95). If it is determined that there is a winning combination (YES), a winning combination processing subroutine (step S96) is performed, and this subroutine is terminated. A detailed description of the winning combination processing subroutine will be described later with reference to FIG.

  If it is determined in step S95 that there is no winning combination (NO), this subroutine is terminated as it is. Hereinafter, a detailed description of the subroutine shown in steps S92, S94, and S96 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, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step 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 NBB value and the NRB value, that is, the BB gaming state and the RB gaming state are canceled. (Step S106), this subroutine is finished.

  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 S107). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input as the NRB value to release the RB gaming state (step S108), and this subroutine is ended. However, in this case, since the BB game continues, the process of inputting 0 to the value of NBB is not performed. If it is determined in step 107 that the RB end condition has not been achieved (NO), this subroutine is ended without releasing the RB gaming state.

  Next, returning to the determination in step S103, when it is determined that the BB game is not being played (NO), that is, the RB game is being played in the normal game, it is next determined whether or not the RB end condition is achieved. (Step S109). If it is determined in this determination 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 this subroutine is ended. If it is determined in step S109 that the RB termination condition has not been achieved (NO), this subroutine is terminated without releasing the RB gaming state.

<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 winning determination and flag off processing subroutine (see FIG. 9). This will be described with reference to the flowchart shown.

  First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step 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 no winning is made (NO), if any flag is on, this flag is turned off (step S123), and the process proceeds to step S128.

  If it is determined in step S122 that there is a prize (YES), it is next 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 to the NRB value to set the RB gaming state (step S125), and the RB flag is turned off (step S126). The process proceeds to step S128. By inputting 1 to the value of NRB, the RB game is played from the next game. For example, in the determination of step S33 in FIG. 6, it is determined that the RB game is in progress.

  If it is determined in step S124 that the RB combination has not won (NO), the general combination flag is turned off (step S127), and the process proceeds to step S128.

  Next, in step S128, 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 S129). If it is determined in this determination that the BB game end condition has been achieved (YES), 0 is input to the NBB value to release the BB game state (step S130), and this subroutine is ended. If it is determined in step S129 that the BB termination condition is not achieved (NO), the BB gaming state is not canceled and the present subroutine is terminated.

<Explanation of the processing sub-routine at the time of winning>
Next, in the determination and flag-off processing subroutine (see FIG. 9), the detailed explanation of the winning combination processing subroutine (see step S96) executed when it is determined in step S95 that there is a winning combination is shown in the flowchart of FIG. To do.

  First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S161). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S162).

  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 S163). In this determination, if it is determined that the BB combination or RB combination has won (YES), 1 is input to the value of NBB or NRB in accordance with the winning combination, and the winning gaming state (BB or RB) is set. (Step S164). Then, the winning BB or RB flag is turned off (step S165), and this subroutine is terminated. By inputting 1 to the value of NBB or NRB, BB and RB games are performed from the next game. For example, in the determination of step S33 or step 35 in FIG. 6, it is determined that the game is BB or RB game.

  If it is determined in step S163 that neither the BB combination nor the RB combination has been won (NO), it is next determined whether or not the re-game combination has won (step S166). If it is determined in this determination that the re-gamer has won (YES), 1 is input to the value of NRP (step S167). By this process, a re-game is performed in the next game (see step S13 in FIG. 5). Then, the re-game flag is turned off. If the BB and RB flags are on, a flag carry-over process is performed (step S168), and this subroutine is terminated.

  If it is determined in step S166 that the re-gamer has not won (NO), the general combination flag is turned off. If the BB and RB flags are on, Carry over processing is performed (step S169), and this subroutine is terminated.

  Returning to the determination in step S162, 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 S170). 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 (general combination, replay combination) are turned on. If so, the flag is turned off (step S171), and this subroutine is terminated.

  If it is determined in step S170 that the BB and RB flags are not turned on (NO), the flag-on flag (general combination, re-playing combination) is turned off (step S172). Exit the subroutine.

<Description of main routine (continued)>
As described above, the subroutine shown in steps S92, S94, and S96 ends, and the winning determination and flag off processing subroutine shown in FIG. 9 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off process subroutine of step S23 is terminated, the payout process of step S24 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.

<Description of production image>
Next, the effect image displayed by the image display means mainly composed of the image control means 510, the display drive circuit 220, and the display device 70 of the sub control circuit 200 will be described. In this embodiment, as shown in FIGS. 20 and 21, there are four types of effect images A to D, and the main character and enemy characters appear and perform battles. Here, the effect image A is the least noticeable effect, the effect images B and C are gradually becoming more prominent effects, and the effect image D is the most prominent effect. In addition, regarding the content of the battle, the enemy image has the most dominant content in the effect image A, the main character gradually becomes dominant in the order of the effect images B and C, and in the effect image D, the protagonist Is the most dominant content.

  As will be described later, one effect image to be displayed by lottery is selected from effect images A to D. In the game state in which the RB and BB flags are set, the effect is more conspicuous. The winning probability of the effect images C and D in which the main character in the battle has more dominant content is set high (see FIG. 21). In addition, in the non-internal gaming state in which the RB and BB flags are not set, the winning probability of the effect images A and B, which is a more inconspicuous effect and the enemy character has more dominant content in the battle, It is set high (see FIG. 20).

  Next, specific contents of the effect image data will be described by using the effect image A and the effect image D as an example. FIG. 22 shows an example of an effect image A in which the enemy character has the most dominant content in the battle with the least noticeable effect, and the effect image in which the main character is the most prominent content in the battle. An embodiment of D is shown in FIG. The effect images A to D are composed of 20 cuts from cut 1 to cut 20, and each cut ends in a relatively short time of 2 to 5 seconds.

  The progress in each cut is set in common in the effect images A to D. In the cuts 1 to 3, the character introduction scene is displayed, in the cuts 4 to 6, the first battle scene is displayed, and the cut 7 is displayed. , 8 display a connection scene prepared for the next development, cuts 9 to 11 display a second battle scene, and cuts 12 to 14 display a connection scene prepared for the next development, and cut In 15-17, the third battle scene is displayed, and in the cuts 18-20, an end scene is displayed. Even if the effect image displayed during the game is changed (for example, change from effect image A to effect image D) by setting the progress of each cut in effect images A to D in common, for each cut Therefore, it is possible to display an effect image in which the player does not feel uncomfortable.

  In addition, the maximum number of cuts that can be displayed is determined for each effect image according to the reel stop state based on the player's stop operation. In the effect image A shown in FIG. 22, when all the reels are rotating (no reel stop operation is performed), up to cut 3 can be displayed (KMAX = 3), and when one reel is stopped, It is set to display up to cut 6 (KMAX = 6) and to display up to cut 14 (KMAX = 14) when two reels are stopped. On the other hand, in the effect image D shown in FIG. 23, when all reels are rotating (no reel stop operation is performed), up to cut 3 can be displayed (KMAX = 3) and one reel is stopped. Then, it is set to display up to cut 8 (KMAX = 8) and to display up to cut 11 (KMAX = 11) when two reels are stopped. That is, in this embodiment, a different value can be set for each effect image for the maximum number of cuts (KMAX) that can be displayed.

  Moreover, in this embodiment, when all the reels stop before the predetermined ratio of the effect image (in this embodiment, cuts 1 to 20) to be displayed during one game is displayed. In the next game, control is performed to display the remaining effect images that were not displayed. Here, the number of continuous determination cuts, which is a criterion for determining whether to display the remaining effect image in the next game or to display the effect image lottery and display a new effect image, is set for each effect image. . For example, in the effect image A shown in FIG. 22, when the number of continuation determination cuts is set to 11 and cuts 12 and after are displayed when all reels are stopped, the effect image lottery is performed in the next game. If a new effect image is displayed from cut 1 and only cuts within cut 11 are displayed when all reels are stopped, in the next game, the same effect image A is displayed from the number of cuts displayed last. It is supposed to be displayed. Further, in the effect image D shown in FIG. 23, the continuation determination number of cuts is set to 14, and when all the reels are stopped and the cut 15 or later is displayed, the effect image lottery is performed in the next game. When a new effect image is displayed from cut 1 and all the reels are stopped and only cuts within the cut 14 are displayed, the same effect image D is displayed from the number of cuts displayed last in the next game. It is supposed to be displayed.

  In addition, for each cut, a changeable cut that can be changed to a different effect image and an unchangeable cut that cannot be changed to a different effect image are set. The setting of the changeable cut or the non-changeable cut is described, for example, in the changeability column in the right column in the examples (tables) of FIGS.

<Explanation of presentation image display>
Next, the flow of displaying the effect image will be described using the examples shown in FIGS. In case 1-1 (see FIG. 24) and case 1-2 (see FIG. 25), after the number of continuation determination cuts is displayed in the first game, all reels stop and the second game Now, a case where an effect image lottery is performed and a new effect image selected by the lottery is displayed from the first cut is shown. In addition, the difference between case 1-1 and case 1-2 shows a case in which the same effect image is displayed in case 1-1 without winning a winning combination in case 1-1, No. 2 shows a case where a winning combination is won by a combination lottery, an effect image lottery is performed again after starting the display of the effect image, and the effect image to be displayed is changed to an effect image selected by lottery from the middle.

  On the other hand, in the case 2-1 (see FIG. 26) and the case 2-2 (see FIG. 27), in the first game, all reels stop before the cut after the continuation determination cut number is displayed. This game shows a case where the remaining images of the effect image displayed in the first game are displayed. Also, the difference between case 2-1 and case 2-2 is that in case 2-1, in the case of case 2-1, the winning effect is not won and the same effect image is displayed. Case 2- No. 2 shows a case where a winning combination is won by a combination lottery, an effect image lottery is performed again after starting the display of the effect image, and the effect image to be displayed is changed to the effect image selected by the lottery from the middle.

  In a game in which a new effect image is displayed from the first cut, a start operation based on the start switch operation of the player, not when a game start signal (see step S20 in FIG. 5) transmitted when the bet is completed is received. When a signal (see FIG. 6, step S32) is received (that is, when the reel starts to rotate), effect image lottery is performed and image display of the selected effect image is started. On the other hand, when the effect image displayed in the previous game is displayed from the last displayed cut, the image display is performed when the game start signal (see step S20 in FIG. 5) transmitted when the bet is completed is received. Start.

  First, case 1-1 shown in FIG. 24 will be described in more detail. First, the first game will be described in the order of display. Since the RB and BB flags are not set, when a start operation signal (see step S32 in FIG. 6) is received, a non-internal medium effect image lottery is performed. The table (see FIG. 20) is read out and effect image lottery is performed, and the selected effect image A is displayed from the cut 1. Further, since there is no winning combination in the winning lottery, the effect image A is continuously displayed. And even if the display of the cut 6 which is the maximum displayable cut (KMAX) at the time of one reel stop in the effect image A is ended, only one reel is stopped, so the second based on the reel stop operation of the player Until the reel stop information signal is received, the display of the cut 6 is continued. Then, after displaying the cut 11 as the continuation determination cut, the display continues until the display of the cut 20. Even after the display of the cut 20 is completed, the remaining one reel continues to rotate, so the display of the cut 20 is continued until all the reels stop.

  Next, in the second game, the RB and BB flags are not set, and the first game is displayed until the cut after the continuation determination cut, so the start operation signal (see step S32 in FIG. 6) is displayed. When received, the non-internal medium effect image lottery table (see FIG. 20) is read out and the effect image lottery is performed, and the selected effect image B is displayed from the cut 1. In addition, since the winning combination lottery of the second game is not won, the effect image B is continuously displayed. Then, after displaying the cut 14 that is the continuation determination cut of the effect image B, all the reels stop where the cut 16 is displayed, and the display of the effect image B is ended.

  Next, in case 1-2 shown in FIG. 25, the first game is exactly the same as in case 1-1. In the second game, as in the case 1-1, when the start operation signal (see FIG. 6, step S32) is received, the effect image lottery by the non-internal medium effect image lottery table (see FIG. 20) is performed, The selected effect image B is displayed from the cut 1. However, in case 1-2, the winning combination was won in the second game lottery, so after starting the display of the effect image B, the internal medium effect image (see FIG. 21) is read and the effect image lottery is performed again. Instead of the displayed effect image B, the effect image D selected by lottery is displayed from the cut 2 corresponding to the number of cuts. The cut 2 of the effect image B is a changeable cut. After that, the effect image D is displayed, and after the cut 14 that is the continuation determination cut of the effect image D is displayed, all the reels stop where the cut 16 is displayed, and the display of the effect image D is ended. .

  However, when the winning combination is won in the second game, it is not always necessary to perform the effect image lottery again after the start of the display of the effect image B, and the effect image B is set to be displayed continuously. You can also

  Next, in the case 2-1 shown in FIG. 26, the first game is an effect based on the non-internal medium effect image lottery table (see FIG. 20) when the start operation signal (see FIG. 6, step S32) is received. Image lottery is performed, and the selected effect image A is displayed from the cut 1. Further, since there is no winning combination in the winning lottery, the effect image A is continuously displayed. However, since the player performed a stop operation at a relatively short interval, all reels stopped before the cut after the number of continuous determination cuts (cut 11) of the effect image A was displayed (cut 10), The display of the effect image A is terminated.

  In the second game, since all the reels are stopped before the first game, the cuts after the number of continuation determination cuts in the effect image A are displayed, a game start signal transmitted when the bet is completed (FIG. 5). , Refer to step S20), the display of the remaining images of the effect image A is started from the cut 10 displayed last in the first game. Also, since there is no winning combination in the second game lottery, the effect image A is continuously displayed, and the display is continued until the cut 20 is reached, and the display of the cut 20 is ended. Since the reels continue to rotate, the display of the cut 20 is continued until all the reels stop. In the second game, when the remaining images of the effect image displayed at the first time are displayed, the maximum displayable cut (KMAX) is not determined.

  Next, in case 2-2 shown in FIG. 27, the first game is exactly the same as in case 2-1. In the second game, as in the case 2-1, when the game start signal (see FIG. 5, step S20) is received, the remaining cut of the effect image A is displayed from the cut 10 displayed last in the first game. Start displaying images. However, in case 2-2, the winning combination was won in the second game lottery, so after starting the display of the effect image A, the internal medium effect image (see FIG. 21) is read and the effect image lottery is performed. The effect image D is selected. However, in the effect image A, since the displayed cut 13 and the next cut 14 are cuts that cannot be changed, the display is changed from the effect image A to the effect image D for the first time when the cut 15 that can be changed is reached. To do. Thereafter, the effect cut D is displayed until the cut 20 is reached, and even if the display of the cut 20 is finished, the reels continue to rotate, so the display of the cut 20 is continued until all the reels stop. .

<Description of effect image display subroutine>
Next, the control process of the effect image display subroutine performed by the image control means 510 of the sub control circuit 200 in order to display the effect image will be described with reference to FIGS. 13 shows an effect image display subroutine, FIG. 14 shows a next cut display subroutine which is a part of the control process of the effect image display subroutine, and FIG. 15 shows a control process of the effect image display subroutine. FIG. 16 shows an effect continuation determination subroutine which is a part of the control process of the effect image display subroutine.

  First, the flowchart of the effect image display subroutine shown in FIG. 13 will be described. First, it is determined whether or not a game start signal is received from the main control circuit 100 (step S200). Here, the game start signal is a signal transmitted from the main control circuit 100 to the sub control circuit 200 when a betting of a game medium is performed (see step S20 in FIG. 5). If it is determined in step S200 that the game start signal has not been received (NO), the control process in step S200 is repeated. That is, it is in a standby state until a game start signal is received.

  If it is determined in step S200 that the game start signal has been received (YES), it is next determined whether or not the value of the parameter KEIZOKU is greater than 0 (step S202). Here, the parameter KEIZOKU determines whether to display the remaining images of the effect image displayed in the previous game, or to perform the effect image lottery and display the new effect image selected in the lottery from the cut 1. It is a parameter for. When it is determined that the cut after the continuation determination cut number is displayed in the previous game, 0 is input to the value of KEIZOKU (see step S504 in FIG. 16), and the cut after the continuation determination cut number is input in the previous game. When it is determined that it is not displayed, 1 is input to the value of KEIZOKU (see FIG. 16, step S508).

  If it is determined in step S202 that the value of KEIZOKU is greater than 0 (YES), the effect image data of the previous game is stored in the RAM 210 as the initial effect game data in the current game (step S204). Proceeding to step S216, image display is started. If it is determined in step S202 that the value of KEIZOKU is 0 or less (NO), it is next determined whether a flag-on signal has been received from the main control circuit 100 (step S206). Here, the flag on signal is a signal transmitted from the main control circuit 100 to the sub control circuit 200 when the RB and BB flags are on at the start of the game (see step S12 in FIG. 5).

  If it is determined in step S206 that the flag-on signal has not been received (NO), the non-internal medium effect image lottery table (see FIG. 20) is read (step S208), and the process proceeds to step S212. If it is determined in step S206 that a flag-on signal has been received (YES), the internal medium effect image lottery table (see FIG. 21) is read (step S210), and the process proceeds to step S212. As described above, in the non-internal medium lottery table shown in FIG. 20, the winning probability is high for the effect images A and B that are more conspicuous effects and the content of the enemy character is more dominant in the battle. In the internal lottery table shown, the winning probabilities of the effect images C and D, which are more conspicuous effects and the content of the character of the main character in the battle, is set high.

  In step S212, lottery processing is performed based on the read effect image lottery table. Specifically, a random number generated by a random number generator (not shown) is extracted by a random number extraction means (not shown), and a random number determination means (not shown) reads out the extracted random number and the above-described read-out. The winner is judged against the lottery table. Then, as a result of the determination, the effect image data selected by lottery is read from the ROM 208 and stored in the RAM 210 as initial effect image data (step S212). Subsequently, it is determined whether or not a start operation signal is received from the main control circuit 100 (step S214). Here, the start operation signal is a signal transmitted from the main control circuit 100 to the sub control circuit 200 when the start switch ON signal is received (see step S32 in FIG. 6).

  If it is determined in step S214 that the start operation signal has not been received (NO), this determination process is repeated. That is, when the value of KEIZOKU is 0 or less and a new effect image selected by effect image lottery is displayed, the image display is not started until the start operation signal is received. If it is determined in step S214 that the start operation signal has been received (YES), the K-th cut effect image of the initial effect image data stored in the RAM 210 is displayed (step S216). . Here, K is a parameter indicating the number of cuts of the effect image to be displayed. When it is determined that the cut after the continuation determination cut number is displayed in the previous game, 0 is input to the value of KEIZOKU and When 1 is input as a value (see step S506 in FIG. 16) and it is determined that the cut after the continuation determination cut number is not displayed in the previous game, 1 is input to the value of KEIZOKU and displayed at that time. A control process for storing the K value as it is is performed (see step S510 in FIG. 16).

  Therefore, if it is determined in step S202 that the value of KEIZOKU is greater than 0 (YES), the last cut of the effect image displayed in the previous game is displayed again, and if it is determined in step S202, KEIZOKU When it is determined that the value of is less than or equal to 0 (NO), cut 1 of the effect image selected in the lottery is displayed. Next, it is determined whether or not an all-reel stop signal has been received (step S218). Here, the all reel stop signal is a signal transmitted from the main control circuit 100 to the sub control circuit 200 when all the reels are stopped.

  If it is determined in step S218 that an all-reel stop signal has been received (YES), an effect continuation determination subroutine in step S228 is performed, and this subroutine is terminated. The effect continuation determination subroutine will be described later. If it is determined in step S218 that all reel stop signals have not been received (NO), it is next determined whether or not the set display time of the Kth cut has elapsed (step S220). . Here, the set display time is a display time set for each cut. For example, in the embodiment (table) of the effect image data shown in FIGS. 22 and 23, it is described as the effect time in the second column from the left. Has been.

  If it is determined in step S220 that the set display time of the Kth cut has not elapsed (NO), the process returns to step S216, and the control processing from step S216 to step S220 is repeated. That is, the display of the Kth cut is continued until the set display time is reached. If it is determined in step S220 that the set display time for the Kth cut has elapsed (YES), the next cut display subroutine is then performed (step S222). Next, the next cut display subroutine will be described in detail with reference to FIG.

<Description of the next cut display subroutine>
In the next cut display subroutine shown in FIG. 14, when the set display time of the Kth cut has elapsed (see step S220 in FIG. 13), the maximum display cut number (KMAX) corresponding to the reel stop state is compared. A control process for determining whether or not to proceed to the next (that is, the (K + 1) th) cut is performed.

  First, it is determined whether or not the value of the parameter K is N or more (step S300). Here, N is the maximum display cut number of the effect image. For example, in the embodiment shown in FIGS. 22 and 23, N = 20. If it is determined in step S300 that the value of K is greater than or equal to N (YES), this subroutine is terminated as it is. That is, when the number of cuts to be displayed has reached the maximum number of cuts to be displayed, the control process for adding 1 to the value of K is not performed, and the display of the same cut (final cut) is continued.

  If it is determined in step S300 that the value of K is smaller than N (NO), it is next determined whether or not the parameter KEIZOKU is larger than 0 (step S301). If it is determined in this determination that the value of KEIZOKU is greater than 0 (YES), the process proceeds to step S316. In other words, when displaying the remaining images of the effect image displayed in the previous game, the process of determining whether or not to proceed to the next cut is performed as compared with the maximum display cut number corresponding to the stop state of the reel. There is nothing.

  If it is determined in step S302 that the value of KEIZOKU is 0 or less (NO), it is next determined whether or not a first reel stop signal has been received from the main control circuit 100 (step S302). . Here, the reel stop information signal is a signal transmitted from the main control circuit 100 to the sub control circuit 200 when the reel stop signal is received (see step S67 in FIG. 8). The reel stop information signal is referred to as a first reel stop information signal. If it is determined in step S302 that the first reel stop information signal has not been received (NO), the maximum display cut number KMAX at the time of all reel rotation of the displayed effect image data is read out next. (Step S304), the process proceeds to step S314. Here, the maximum display cut number KMAX when all reels are rotated is KMAX = 3 in the case of the effect image A shown in FIG. 22 and the effect image D shown in FIG. 23, for example.

  If it is determined in step S302 that the first reel stop information signal has been received (YES), it is next determined whether a second reel stop signal has been received from the main control circuit 100 (step S306). ). Here, the second reel stop information signal is a reel stop information signal when the second reel is stopped. If it is determined in step S306 that the second reel stop information signal has not been received (NO), the maximum display cut number KMAX at the time of one reel stop of the displayed effect image data is read out next. (Step S308), the process proceeds to step S314. Here, the maximum display cut number KMAX when one reel is stopped is, for example, KMAX = 6 for the effect image A shown in FIG. 22, and KMAX = 8 for the effect image D shown in FIG.

  If it is determined in step S306 that the second reel stop information signal has been received (YES), it is next determined whether or not a third reel stop signal has been received from the main control circuit 100 (step S310). ). Here, the third reel stop information signal is a reel stop information signal when the third reel is stopped. If it is determined in step S310 that the third reel stop information signal has not been received (NO), then the maximum display cut number KMAX at the time of two reel stops of the displayed effect image data is read. (Step S312), the process proceeds to step S314. Here, the maximum display cut number KMAX when the two reels are stopped is, for example, KMAX = 14 for the effect image A shown in FIG. 22, and KMAX = 11 for the effect image D shown in FIG. If it is determined in step S310 that the third reel stop information signal has been received (YES), the process proceeds to step S316.

  In step S314, it is determined whether or not the value of parameter K is greater than KMAX (step S314). If it is determined in this determination that the value of K is equal to or greater than KMAX (YES), this subroutine is terminated as it is. If it is determined in step S314 that the value of K is smaller than KMAX (NO), control processing for adding 1 of the value of K is performed (step S316), and this subroutine is terminated. Since this subroutine is repeatedly performed in the effect image display subroutine shown in FIG. 13, the K-th cut after the set display time has elapsed is the reel stopped state (when all reels are rotated, when one reel is stopped, or when two reels are used). If the maximum display cut number KMAX determined in accordance with (when stopped) is greater than or equal to KMAX, the display of the same cut is continued until the rotating reel stops and a new stop information signal is received. In addition, if the Kth cut after the set display time has passed is smaller than the maximum display cut number KMAX determined according to the reel stop state, the set display time is passed until the K value reaches KMAX. , K is added to 1 to display a new cut. When the third reel stop signal is received (step S310, YES), since all reels are stopped, the value of K is increased every time the set display time elapses until the maximum display cut number N is reached. Add 1 to display a new cut.

<Description of effect image display subroutine (continued)>
Returning to the description of the effect image display subroutine shown in FIG. 13 again, following the next cut display subroutine in step S222, it is determined whether or not an RB / BB winning signal has been received from the main control circuit 100 (step S224). Here, the RB and BB winning signals are signals transmitted from the main control circuit 100 to the sub-control circuit 200 when the RB and BB winning combinations are won in the winning lottery (see step S44 in FIG. 7). If it is determined in step S224 that the RB and BB winning signals are not received (NO), the process returns to step S216, and the control processing from step S216 to step S224 is repeated. That is, if the RB or BB combination is not won in the combination lottery, a new cut of the same effect image is displayed as the set display time elapses. If it is determined in step S218 that all reel stop signals have been received (YES), an effect continuation determination subroutine in step S228 is performed, and this subroutine is terminated.

  If it is determined in step S224 that an RB or BB winning signal has been received (YES), then a winning combination winning effect image display subroutine is performed (step S226). When it is determined in step S202 that the value of the parameter KEIZOKU is 0 or less (NO), that is, when a new effect image is displayed from the first cut after receiving the start signal, the determination in step S224 is performed. Even if it is determined that the RB and BB winning signals have been received (YES), the control processing from step S216 to step S224 can be repeated without proceeding to the winning combination winning effect image display subroutine. Next, with reference to FIG. 15, a detailed description of the winning effect winning effect image display subroutine will be given.

<Description of effect image display subroutine when winning a winning combination>
When the winning combination winning effect image display subroutine shown in FIG. 15 is received, when the RB and BB winning signals are received, the effect image lottery process is newly performed, and the control process of displaying the effect image selected in the lottery is performed.

  First, an internal medium effect image lottery table (see FIG. 21) is read (step S400). Next, a lottery is performed based on the read internal medium effect image lottery table. As a result of the determination, the effect image data selected by the lottery is read from the ROM 208 and stored as the changed effect image data in the RAM 210 (step S402). Here, if the slot machine has a setting in which a plurality of hit flags (RB, BB flag) cannot be turned on, the initial effect image selected in the lottery based on the non-internal medium effect image lottery table is displayed. Sometimes, the lottery based on the inside medium effect image lottery table is performed again, and the effect image to be displayed is selected. Therefore, since the effect images that are easy to win differ between the internal medium effect image lottery table and the non-internal medium effect image lottery table, in this case, there is a high possibility that the effect image to be displayed is changed between one game. It can be said.

  Subsequent to step S402, it is determined whether or not the Kth cut being displayed is a changeable cut (step S404). If it is determined in this determination that the Kth cut is not a changeable cut (NO), the Kth cut of the displayed initial effect image data is displayed as it is (step S406). Then, it is determined whether or not all reel stop signals have been received (step S408), whether or not the set display time of the Kth cut has elapsed (step S410), and the next cut display subroutine (step S412). Do. Since the control processing of steps S406, S408, S410, and S412 is the same as the control processing of steps S216, S218, S220, and S222 of the effect image display subroutine shown in FIG. 13, detailed description thereof is omitted.

  As described above, the control processing from step S404 to step S412 is repeated, and 1 is added to the value of K to display a new cut. If it is determined in step S404 that the new Kth cut is a changeable cut (YES), then the Kth cut of the changed effect image data is displayed (step S414).

  This will be described in the embodiment of FIG. 27. Even when the effect image D is selected by the effect image lottery, the cut 13 being displayed and the next cut 14 are cuts in which the effect image A cannot be changed ( In FIG. 22, when the cut 15 that is a changeable cut is reached, a control process for changing from the effect image A (initial effect image) to the effect image D (change effect image) is performed. If it is determined in step S404 that the Kth cut is a changeable cut (YES) and it is determined in step S408 that an all-reel stop signal has been received (YES), the present cut is made. The subroutine ends.

  Subsequent to the control process for displaying the Kth cut of the changed effect image data in step S414, it is determined whether or not all reel stop signals have been received (step S416), and whether the set display time for the Kth cut has elapsed. A determination of whether or not (step S418) and a next cut display subroutine (step S420) are performed. Since the control processing in steps S414, S416, S418, and S420 is the same as the control processing in steps S216, S218, S220, and S222 of the effect image display subroutine shown in FIG. 13, detailed description thereof is omitted.

  As described above, the control processing from step S414 to step S420 is repeated, and 1 is added to the value of K to display a new cut. If it is determined in step S416 that all reel stop signals have been received (YES), this subroutine is terminated.

<Description of effect image display subroutine (continued)>
Returning again to the description of the effect image display subroutine shown in FIG. 13, the all reels stop signal is determined by the determination in step S218 or the determination in steps S408 and S416 (see FIG. 15) of the effect image display subroutine at the time of winning the winning combination in step S226. When it is determined that it has been received (YES), an effect continuation determination subroutine is performed, and this subroutine is terminated. Next, a detailed description of the effect continuation determination subroutine will be described with reference to FIG.

<Description of production continuation determination subroutine>
The effect continuation determination subroutine shown in FIG. 16 determines whether to display a new effect image selected by effect image lottery from the cut 1 in the next game or display the remaining effect image displayed in the game. Control processing is performed.

  First, the continuation determination cut number of the effect image data that has been displayed is read (step S500). For example, in the effect image A shown in FIG. 22, the continuation determination cut number is 11, and in the effect image D shown in FIG. Next, it is determined whether or not the parameter K, which is the number of cuts when the reel is stopped, is larger than the read continuous determination cut number (step S502). In this determination, if it is determined that the value of K is greater than the number of cuts for continuation determination (YES), then 0 is input to the value of parameter KEIZOKU (step S504), and 1 is input to the value of parameter K Then, initialization is performed (step S506), and this subroutine is terminated. That is, in the next game, the effect image lottery is performed and the selected effect image is displayed from the cut 1.

  If it is determined in step S500 that the value of K is equal to or less than the continuation determination cut number (NO), next, 1 is input to the value of the parameter KEIZOKU (step S508), and the current value is set as the parameter K. Is stored as it is (step S510), and this subroutine is terminated. That is, in the next game, the same effect image is displayed from the current K-th cut. As described above, it is possible to display the effect image as shown in the embodiments of FIGS.
