Description

  The present invention relates to a gaming machine.

  Conventionally, a start lever has been operated by a player on condition that a plurality of reels each having a plurality of symbols arranged on each surface are provided side by side, and medals, coins, etc. (hereinafter, medals, etc.) are inserted. (Hereinafter, a start operation) is detected, and a start switch that outputs a signal requesting the start of rotation of all reels and a stop button provided for each of the plurality of reels are pressed by the player. (Hereinafter referred to as “stop operation”), a stop switch for outputting a signal for requesting the rotation of the corresponding reel to stop, and a corresponding drive force for each reel. The stepping motor that is transmitted to the controller and the signals output from the start switch and stop switch are used to control the operation of the stepping motor. Rotation and gaming machine that includes a control unit that performs a stop, the are known.

  In the gaming machine as described above, when a start operation by a player is detected, a lottery process using random numbers (hereinafter referred to as an internal lottery process) is performed on a program. The combination of symbols that are allowed to be displayed is determined. The internal lottery process refers to a data table (hereinafter referred to as an internal lottery table) that defines a plurality of types of internal winning combinations and random values (in other words, winning probability) when each internal winning combination is determined. An internal winning combination is determined based on the random value extracted based on the detection.

  Then, the rotation of each reel is stopped based on the internal winning combination and the timing when the stop operation by the player is detected. When a combination of symbols related to winning is displayed as a result of the rotation of all reels being stopped, the player receives a bonus associated with the symbol combination, such as paying out medals, etc., or operating a bonus gaming state. Is granted to.

  In such a gaming machine, as a privilege to be given to the player, the one that performs the operation of “re-game” that can obtain the result of the internal lottery process without consuming medals or the like next time is mainstream. The probability variation state (hereinafter referred to as “this”) is determined with a relatively high probability (or “low probability”) of the internal winning combination (hereinafter referred to as “replay”) that permits display of the combination of symbols relating to the operation of this replay. Is known as a replay time and is abbreviated as “RT”). When replays are determined with a relatively high probability, the chances for replay operations to increase and the consumption of medals and the like can be reduced, so that it is possible to improve interest while maintaining the soundness of the game. it can.

  Recently, with respect to the RT as described above, the first RT (hereinafter referred to as RT1) is operated based on the first condition, and the second condition based on the second condition different from the first condition. A gaming machine has been proposed that performs the operation of the third RT (hereinafter referred to as RT3) based on the third condition different from the first condition and the second condition. (For example, refer to Patent Document 1).

  Specifically, the first condition is that the winning of Replay B is established among the two types of replays (Replay A and Replay B). When this first condition is satisfied, RT1 operates and RT1 During the operation, the internal lottery process is executed with reference to the RT1 internal lottery table. The RT1 internal lottery table has a higher probability of winning Replay A than an internal lottery table (hereinafter referred to as a general gaming state internal lottery table) that is referred to when neither the bonus gaming state nor the RT is operating. It is configured.

  Also, the second condition is that the operation of BB2 of the two types of bonus game states (BB1 and BB2) has been completed. When this second condition is satisfied, RT2 is activated, while RT2 is in operation. The internal lottery process is executed with reference to the RT2 internal lottery table. The RT2 internal lottery table is configured so that the winning probability of the replay B is higher than that of the general gaming state internal lottery table.

Further, the third condition is that the operation of BB1 has been completed out of the two types of bonus game states (BB1 and BB2). When this third condition is satisfied, RT3 is activated, while RT3 is in operation. The internal lottery process is executed with reference to the RT3 internal lottery table. The internal lottery table for RT3 is configured such that the winning probability of Replay A and the winning probability of Replay B are both higher than the internal lottery table for general gaming state.
JP 2007-289414 A

  However, in the conventional gaming machine described above, when the first condition, the second condition or the third condition is satisfied, an internal lottery table corresponding to the satisfaction condition is set. The winning probability of the replays (Replay A and Replay B) is uniformly set. When the operation of each RT is finished by counting a predetermined number of games, the general gaming state internal lottery table is set. At this time, the winning probability of all replays is the same as before the change. Since it was set uniformly on the object, it was not possible to give the gameability elastically.

  That is, for example, if the above third condition is satisfied, it is possible to change both the winning probability of Replay A and the winning probability of Replay B, but after that, while changing the winning probability of Replay A, When returning the winning probability of Replay B to that before the change, it is necessary to separately define a new condition such as the first condition, and a dedicated internal lottery table as described above is defined. Need arises.

  For this reason, the more you want to make your game more diverse, the more you have to define the prescribed conditions and the prescribed internal lottery table, which increases the control burden and presses the storage area capacity. End up. On the other hand, if the number of types of operating RTs is not increased from the viewpoint of control burden, storage area capacity, etc., the game becomes monotonous and naturally the interest of the game is reduced.

  Therefore, an object of the present invention is to provide a gaming machine that can give a variety of gaming properties elastically while suppressing an increase in control burden and the like.

  In order to achieve the above object, the present invention provides the following gaming machines.

(1) A plurality of reels (for example, reels 3L, 3C, and 3R described later) each having a plurality of symbols arranged on each surface, and a random value extraction means (for example, a random value extraction unit that extracts a random value based on detection of a start operation) An internal winning combination (e.g., replay-replay-replay described later) that allows display of a combination of the first symbols related to the replay operation (e.g., replay-replay-replay described later). Replay A described later) , an internal winning combination (for example, Replay B described later) that permits display of a second symbol combination (for example, Chance-Replay-Replay described later) related to replay operation and replay operation A plurality of types of internals including an internal winning combination (for example, replay C described later) that permits display of a third symbol combination (for example, chance-chance-chance described later) Refer to a data table (for example, an internal lottery table for general gaming state described later) that defines a random value when each winning combination is determined, and based on the random value extracted by the random value extracting means, Internal lottery means for determining the winning combination (for example, internal lottery processing described later), reel rotating means for rotating each of the plurality of reels (for example, stepping motors 49L, 49C, 49R described later), and the type of the reel In response to the stop operation detecting means (for example, a stop switch 7S described later) for detecting the stop operation in response to the detection of the stop operation performed by the stop operation detecting means and the internal winning combination determined by the internal lottery means Based on the reel stop means (for example, a reel stop control process described later) for stopping the rotation of the corresponding reel, and the reel stop means As a result of the rotation of the number of reels being stopped, when a combination of symbols relating to the replay operation is displayed by the plurality of reels, replay operation means for performing the replay operation (for example, bonus operation check processing described later) S187) and when a predetermined condition is satisfied (for example, on the condition that the operation of the BB described later has been completed), a first probability variation state (for example, RT1 described later) and a second probability variation state ( For example, a probability variation state actuating means (for example, S154 in a bonus end check process described later) that operates each of a third probability variation state (for example, RT3 described later) together with RT2 described later, and the probability variation state operation means described above. Allows the display of the first symbol combination among the random values defined by the data table when the first probability variation state is activated by First changing means (for example, an internal lottery, which will be described later), which changes the random number value when the part winning combination (for example, replay A, which will be described later) is determined to have a higher probability than when the operation is not performed S97) of the table determination process, and when the operation of the second probability variation state is performed by the probability variation state operation means, among the random values defined by the data table, Second changing means for changing a random value when an internal winning combination (for example, replay B described later) that permits display of the combination is determined to have a higher probability than when the operation is not performed ( For example, when the operation of the third probability variation state is performed by the probability variation state actuating means (S99) of the internal lottery table determination process to be described later and the probability variation state operation means, it is defined by the data table. Among the random number values, a random number value when an internal winning combination (for example, replay C described later) that permits display of the third symbol combination is determined is higher than when the operation is not performed. Third changing means (for example, S101 in an internal lottery table determination process described later) for changing to be a probability, and game number counting means (for example, an RT control process described later) for counting the number of games based on detection of the start operation S162, S166), and the number of games counted by the number-of-games counting unit after the operation of the first probability variation state is performed by the probability variation state operation unit is a first number (for example, 150 times described later) If) is reached, regardless of whether the front Ki確 rate variation state actuating means actuating the operation及beauty third probability variation state of the second probability variation state is performed, the probability First probability variation state ending means (for example, S164 of RT control processing described later) for ending only the operation of the first probability variation state performed by the variation state operation means, and second operation by the probability variation state activation means. second number different from the counted number of games by the game number counting means from the operation is performed in the probability change state and the first number of (e.g., 100 times below) is reached, before Ki確 regardless of whether the rate change condition actuating means actuating及beauty third probability variation state of the first probability variation state operation is being performed, the second probability being performed by the probability change state actuating means After the operation of the third probability variation state is performed by the second probability variation state ending means (for example, S168 of RT control processing described later) for ending only the operation of the variation state and the probability variation state operation means. Serial number of games counting means by counted as the number of games the first count and the second count third number of respectively different (e.g., 50 times below) is reached, before Ki確 rate variation state operation third probability variation state of the working及beauty second probability variation state of the first probability variation state operation regardless of whether it is performed, is performed by pre Ki確 rate variation state actuation means by means And a third probability variation state ending means for ending only the operation of the game machine (for example, S172 of RT control processing described later).

  According to this gaming machine, the internal winning combination is determined based on the extracted random number value with reference to the data table that defines the random number value when plural types of internal winning combinations are determined. Then, when the operation of the first probability variation state (hereinafter referred to as the first RT) is performed, an internal winning that permits the display of the first symbol combination relating to the operation of the replay specified by the data table. The random number value when the combination (hereinafter referred to as the first replay) is determined is changed. On the other hand, when the operation of the second probability variation state (hereinafter referred to as the second RT) is performed, the display of the second symbol combination related to the operation of the replay specified by the data table is permitted. The random value when the internal winning combination (hereinafter referred to as second replay) is determined is changed.

  That is, the data table is provided according to each RT, and the random number value when all replays are determined by changing the data table to be referred by the operation of each RT is referred to without being uniformly changed. The winning probability of the replay can be changed by separately changing only the random value when the replay unique to each RT is determined without changing the data table.

  In addition, when a predetermined condition is satisfied, each of the first RT and the second RT is operated, and thereafter, when the number of games counted after each RT is operated reaches the first number of times. When the number of games counted since the activation of each RT reaches a second number different from the first number, the second RT is deactivated. I ended it. In other words, by ending the operation of each RT by counting a different number of times from when the predetermined condition is satisfied, the operation is performed while returning the winning probability of each replay separately to the one before the change. With regard to the continuing RT, the winning probability of the replay after the change can be inherited as it is.

  That is, for example, when the first RT operation and the second RT operation are respectively performed, the winning probability of the first replay and the winning probability of the second replay both fluctuate. When the operation of the second RT is finished first, only the winning probability of the second replay is returned before the change, so that a state in which only the winning probability of the first replay is changed can be created. Therefore, when the winning probability of one replay is changed from the state where the winning probability of a plurality of replays is changed and the winning probability of the other replay is returned to the one before the change, the operation of each RT is changed. It is only necessary to finish the process, and it is not necessary to provide a new condition and a new data table. As a result, it is possible to give various versatility with elasticity while suppressing an increase in control burden.

  As a more detailed configuration, when the first RT operation is performed, the winning probability of the first replay is highly varied, and when the second RT operation is performed, the winning probability of the second replay is highly varied. Therefore, in the process of counting the fixed number of games after the start of each RT operation, it is possible to add a game property in which the winning probability of replay gradually decreases. It has become.

  That is, for example, when “first number> second number” is satisfied, until the number of games counted after the start of each RT operation reaches the second number, By the operation of the second RT, the winning probability of the first replay and the winning probability of the second replay are both high. When the number of games reaches the second number and the operation of the second RT is finished, only the winning probability of the first replay is high. After that, when the number of games reaches the first number and the operation of the first RT is finished, the winning probability of the first replay and the winning probability of the second replay are both low. In this way, compared to the case where the winning probability of replay is reduced at once, the expectation of the player can be prevented from being significantly reduced, and the interest of the game is improved. Can do.

Further , when a predetermined condition is satisfied, the third RT operation is further performed together with the first RT operation and the second RT operation, and the third RT state operation is performed. When the operation is performed, a random value when an internal winning combination (hereinafter referred to as a third replay) that permits display of the third symbol combination relating to the replay operation specified by the data table is determined. Change the winning probability to be higher.

  Then, when the number of games counted after the predetermined condition is satisfied reaches the first number, the operation of the first RT is terminated, and the second number of games is different from the first number. When the number of times is reached, the operation of the second RT is terminated, and when the number of games reaches a third number different from the first number and the second number of times, the operation of the third RT is terminated. I did it.

  In other words, by increasing the number of replays that each change the winning probability separately when a predetermined condition is satisfied, and by making the number of games that trigger the change different, the winning probability of the replay Therefore, it is possible to set the stage in which the game becomes lower in detail, so that the expectation of the player is not significantly lowered, and it is suitable for improving the interest of the game.

  According to the gaming machine of the present invention, the internal winning combination is determined based on the extracted random value by referring to the data table that defines the random number value when plural types of internal winning combinations are determined. Then, when a predetermined condition is satisfied, each of the RTs is operated, and only the random value when the replay specific to each RT is determined among the random values defined by the data table is separately provided. Change to In addition, each RT is terminated by counting a different number of times, and only the random value when the replay unique to each RT is determined is individually returned to the one before the change. In addition, it is possible to give a variety of flexibility in a flexible manner while suppressing an increase in control burden.

If the symbol combination displayed along the winning determination line does not match any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

  The symbol combination table defines a symbol combination, a display combination, and a payout number that are predetermined according to the type of privilege. The display combination is data for identifying a combination of symbols displayed along the winning determination line.

  The display combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. For example, when the symbol “bell” of the left reel 3L, the symbol “bell” of the middle reel 3C, and the symbol “bell” of the right reel 3R are displayed along the winning determination line, “bell A (00000010)” is displayed as a display combination. Is determined.

  When a numerical value of 1 or more is determined as the payout number, medals are paid out. In this embodiment, when a cherry, bell A or bell B is determined as a display combination, medals are paid out. The number of payouts is defined according to the number of inserted sheets. Basically, a larger number of paid-out sheets is determined when the number of inserted sheets is small.

  When the symbol “replay” of the left reel 3L, the symbol “replay” of the middle reel 3C, and the symbol “replay” of the right reel 3R are displayed along the winning determination line, the replay A is determined as the display combination, The game is activated. The symbol combination “replay-replay-replay” relating to replay A is an example of a first symbol combination relating to replay operation.

  When the symbol “chance” of the left reel 3L, the symbol “replay” of the middle reel 3C, and the symbol “replay” of the right reel 3R are displayed along the winning determination line, the replay B is determined as the display combination, The game is activated. The symbol combination “chance-replay-replay” related to replay B is an example of a second symbol combination related to the operation of replay.

  When the symbol “chance” of the left reel 3L, the symbol “chance” of the middle reel 3C, and the symbol “chance” of the right reel 3R are displayed along the winning determination line, the replay C is determined as the display combination, The game is activated. The symbol combination “chance-chance-chance” related to Replay A is an example of a third symbol combination related to the replay operation.

  When the symbol “red 7” of the left reel 3L, the symbol “red 7” of the middle reel 3C, and the symbol “red 7” of the right reel 3R are displayed along the winning determination line, BB is determined as the display combination. The operation of a big bonus (hereinafter abbreviated as BB) is performed.

  In this embodiment, the operation of the first RT (hereinafter referred to as RT1), the operation of the second RT (hereinafter referred to as RT2) will be described on the condition that the operation of BB has ended. The operation and the operation of the third RT (hereinafter, RT3) are performed. Then, each RT ends its operation on condition that the number of games counted since the start of each operation (that is, after the end of the operation of BB) has reached a predetermined number for each RT. To do. RT1 ends its operation on condition that the number of games reaches 150. RT2 ends its operation on condition that the number of games reaches 100. RT3 ends its operation on condition that the number of games reaches 50.

  Next, the bonus operation time table will be described with reference to FIG. The bonus operation time table specifies data to be stored in the storage areas of the game state flag storage area, the game possible number counter and the winning possibility number counter provided in the main RAM when the bonus game state is operated. Yes.

  The game state flag is data for identifying the type of bonus game state in which the operation is performed. In the present embodiment, BB (a combination continuous action device relating to a first type special combination) and a regular bonus (a first type special combination) are provided as bonus game state types.

  As will be described in detail later, the operation of the regular bonus (hereinafter abbreviated as RB) is continuously performed while the operation of BB is performed (see S188 to S190 in FIG. 26 described later). When the operation of BB and the operation of RB are performed, an internal winning combination that permits display of a combination of symbols related to the payout of medals is determined with a relatively high probability.

  The operation of BB ends when a medal that reaches the specified number is paid out. The operation of the RB ends when the game reaches the specified number of times, when there is a winning that reaches the specified number of times, or when the operation of the BB ends. The bonus end number counter, the possible game number counter, and the winning number counter are data for managing whether or not the specified number of times or the specified number of times as a trigger for ending the bonus gaming state has been reached.

  More specifically, numerical values defined by the bonus operation time table are stored in the respective counters, and the subtraction is performed through the operation of the bonus game state. As a result, the operation of the corresponding bonus game state is completed on condition that the value of each counter is updated to “0”.

  Next, the internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. The data pointer is data acquired as a result of lottery performed with reference to an internal lottery table described later, and is data for designating an internal winning combination. The data pointer is provided with a small role / replay data pointer and a bonus data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols permitted to be displayed by three reels along the winning determination line. Like the display combination, the internal winning combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit.

  FIG. 8 shows a small winning combination / replay internal winning combination determination table. The internal winning combination determination table for small roles and replays defines internal winning combinations that allow display of symbol combinations related to medal payout or internal combinations that allow display of symbol combinations related to replay operations. Yes. FIG. 9 shows a bonus internal winning combination determination table. The bonus internal winning combination determination table defines an internal winning combination that permits display of a combination of symbols related to the operation of the bonus game state.

  For example, when the small combination / replay data pointer is “5”, “replay B” is determined as the internal winning combination, and as a result, the symbol “chance” of the left reel 3L, the symbol “replay” of the middle reel 3C, and The display of the symbol combination consisting of the symbol “replay” on the right reel 3R is permitted. When each data pointer is “0”, “losing” is determined as an internal winning combination, and this means that display of any combination of symbols defined by the above-described symbol combination table is not permitted. Show.

  Here, in the present embodiment, when the stop button is pressed by the player, the combination of symbols permitted by the internal winning combination within the range of the maximum number of sliding pieces “4” as a rule is along the winning determination line. Thus, the rotation of each reel is stopped so as to be displayed as much as possible (so-called pull-in). On the other hand, the rotation of each main reel is stopped (so-called kicking) so that the combination of symbols not permitted by the internal winning combination is not displayed along the winning determination line.

  Next, the internal lottery table will be described with reference to FIGS. The internal lottery table defines a small role / replay data pointer and bonus data pointer according to the winning number, and a lottery value when each data pointer is determined.

  In the present embodiment, random numbers extracted from a predetermined numerical range “0 to 65535” are sequentially subtracted by lottery values corresponding to each winning number, and whether or not the result of the subtraction is negative ( An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  The lottery value defines a random value when data assigned to it (that is, a data pointer and an internal winning combination) is determined, and more specifically, the size of the set of random values. It can be said that it stipulated. When the lottery value is “150”, for example, it means a set of 150 consecutive random number values from “0” to “149”.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data to which it is assigned (that is, the data pointer and the internal winning combination) will be determined. The winning probability of each winning number can be represented by “the lottery value corresponding to each winning number / the number of all random numbers that may be extracted (65536)”.

  FIG. 10 shows an internal lottery table for a general gaming state. The internal lottery table for the general gaming state defines lottery values and data pointers corresponding to the winning numbers 1 to 9. When the winning number is “6”, “8980” is defined as the lottery value when the internal winning combination “Replay A” is determined. Further, when the winning number is “7”, “1” is defined as the lottery value when the internal winning combination “Replay B” is determined. Furthermore, when the winning number is “8”, “1” is defined as the lottery value when the internal winning combination “Replay C” is determined.

  FIG. 11 shows an RB gaming state internal lottery table which is referred to during RB operation. The RB gaming state internal lottery table defines lottery values and data pointers corresponding to the winning number 1. In the internal lottery table for RB operation, the probability that an internal winning combination permitting display of a symbol combination related to the payout of medals is higher than that in the internal lottery table for the general gaming state.

  Next, a lottery value change table will be described with reference to FIGS. The lottery value change table defines the winning number and the lottery value after the change for which the lottery value is to be changed in the aforementioned internal lottery table for general gaming state. The lottery value change table is provided for each RT, and is referred to when an RT that is associated in advance is being operated.

  FIG. 12 shows an RT1 operating lottery value change table. When the RT1 operation is performed, the lottery value “8980” corresponding to the winning number 6 in the internal lottery table for the general gaming state is changed to the lottery value “17690” defined by the RT1 operating lottery value change table. Is done. As a result, during the operation of RT1, the winning probability of the internal winning combination “Replay A” is higher than when the operation is not performed.

  FIG. 13 shows a lottery value change table for RT2 operation. When the RT2 operation is performed, the lottery value “1” corresponding to the winning number 7 in the internal lottery table for the general gaming state is changed to the lottery value “17690” defined by the RT2 operating lottery value change table. Is done. As a result, during the operation of RT2, the winning probability of the internal winning combination “Replay B” is higher than when the operation is not performed.

  FIG. 14 shows an RT3 operating lottery value change table. When the RT3 operation is performed, the lottery value “1” corresponding to the winning number 8 in the internal lottery table for the general gaming state is changed to the lottery value “17690” defined by the RT3 operating lottery value change table. Is done. As a result, during the operation of RT3, the winning probability of the internal winning combination “Replay C” is higher than when the operation is not performed.

  As described above, in this embodiment, when each operation of RT1, RT2 and RT3 is performed on condition that the operation of the bonus game state is completed, the replay associated with each RT is determined. Only the lottery value is changed individually.

  In addition, by terminating the operation of each RT according to different conditions, the winning probability of each replay is individually returned to the one before the change, while the RT that continues to operate is determined for the replay after the change. Probability can be inherited as it is. For example, when the operation of each RT is performed and the operation of RT3 is ended, the winning probability of Replay A (17690/65536) and the winning probability of Replay B (17690/65536) changed by RT1 and RT2 where the operation continues. 17690/65536), it is possible to return only the winning probability (17690/65536) of the replay C that has changed due to RT3 when the operation ends to the previous one (1/65536).

  Next, the configuration of various storage areas provided in the main RAM 32 will be described with reference to FIGS.

  First, the configuration of the internal winning combination storing area will be described with reference to FIG. The internal winning combination storing area stores the internal winning combination represented by the above-mentioned 1-byte data. When “1” is set in the bit constituting the internal winning combination storing area, display of the corresponding symbol combination is permitted.

  In the present embodiment, for example, when the small combination / replay data pointer is “6”, “Cherry + Bell A + Bell B (00000111)” is determined as the internal winning combination. When “1” is set to “1”, all display of the corresponding symbol combination is permitted. Then, based on the timing at which the stop button is pressed by the player, any one of the corresponding combinations of the symbols is displayed along the winning determination line. When all the bits are “0”, the content is lost.

  The main RAM is provided with a display combination storage area in which the display combination is stored. The configuration of the display combination storing area is the same as the configuration of the internal winning combination storing area. When “1” stands for the bit constituting the display combination storing area, the corresponding symbol combination is displayed along the winning determination line.

  Next, the configuration of the carryover combination storage area will be described with reference to FIG. As a result of the lottery performed with reference to the internal lottery table described above, when the internal winning combination “BB” allowing the display of the combination of symbols related to the operation of the bonus is determined, this is stored in the carryover combination storage area Is done. The internal winning combination (hereinafter referred to as the carryover combination) stored in the carryover combination storage area is held without being cleared until the corresponding symbol combination is displayed on the winning determination line. . And while the carryover combination is stored in the carryover combination storage area, it is stored in the internal winning combination storage area regardless of the result of the lottery described above.

  Next, the configuration of the game state flag storage area will be described with reference to FIG. The gaming state flag storage area stores a gaming state flag consisting of 1 byte. In the game state flag, a unique bonus game state is assigned to each bit. When “1” is set in the bit constituting the gaming state flag storage area, the corresponding bonus gaming state is activated. The state when all bits are “0” is defined as a general gaming state.

  Next, the configuration of the RT operating flag storage area will be described with reference to FIG. The RT operating flag storage area stores a 1-byte RT operating flag. The RT operating flag is assigned a unique RT for each bit. When “1” is set in the bit constituting the RT operating flag storage area, the corresponding RT is operating. When all the bits are “0”, it indicates that no RT operation is performed.

  Next, the contents of the program executed by the main CPU of the main control circuit will be described with reference to FIGS.

  First, with reference to FIG. 19, the main flowchart by control of main CPU is demonstrated. When power is supplied to the pachislot machine, first, the main CPU 31 performs an initialization process (S1). Next, the main CPU 31 clears the designated storage area in the main RAM (S2). For example, data stored in a storage area that needs to be erased for each game, such as an internal winning combination storage area or a display combination storage area, is cleared.

  Next, the main CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 20 (S3). In this process, the medal sensor and start switch input are checked.

  Next, the main CPU 31 extracts a random value and stores it in a random value storage area provided in the main RAM (S4). Next, the main CPU 31 performs an internal lottery process which will be described later with reference to FIG. 21 (S5). In this process, the internal winning combination is determined by lottery based on a random value.

  Next, the main CPU 31 refers to the stop table determination table and determines the stop table based on the gaming state and the internal winning combination (S6). The stop table stores data (hereinafter referred to as stop data) for determining the position of the symbol displayed in the middle of the corresponding display window when the rotation of each reel is stopped. 20 ”. Next, the main CPU 31 transmits a start command to the sub-control circuit (S7). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 31 requests the start of rotation of all main reels (S8). When the start of rotation of all the main reels is requested, the driving of the stepping motors 49L, 49C, 49R is controlled by an interrupt process (FIG. 27 to be described later) executed at a constant cycle (1.1173 msec). The rotation of the reels 3L, 3C, 3R is started.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 23 (S9). In this process, the input of the stop switch is checked, and the rotation of the corresponding reel is stopped based on the timing when the stop button is pressed, the internal winning combination and the stop table.

  Next, the main CPU 31 refers to the symbol combination table and determines a display combination or the like based on the symbol combination displayed along the winning determination line (S10). It is determined whether or not the symbol combination displayed along the winning determination line matches the symbol combination defined by the symbol combination table. If the symbol combination matches, the corresponding display combination and payout are determined. The number of sheets is determined. Next, the main CPU 31 transmits a display command to the sub control circuit (S11). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 31 performs medal payout processing (S12). Based on the determined payout number, the hopper is driven and the credit number is updated. Next, the main CPU 31 updates the bonus end number counter based on the payout number (S13). The numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 31 determines whether or not the BB gaming state flag is on (S14). When determining that the BB gaming state flag is on, the main CPU 31 performs a bonus end check process which will be described later with reference to FIG. 24 (S15). It is checked whether or not to end the bonus operation with reference to various counters for managing the bonus end timing.

  When the main CPU 31 determines in S14 that the BB gaming state flag is not on, it performs RT control processing which will be described later with reference to FIG. 25 (S16). In this process, it is checked whether or not to end the operation of RT.

  RT1, RT2, and RT3 of the present embodiment end their operations when a game that reaches a specified number of times is played. The main RAM 33 is provided with an RT1 game number counter, an RT2 game number counter, and an RT3 game number counter as data for managing whether or not the specified number of times that triggers the end of each RT has been reached. For example, when RT1 is activated, a predetermined numerical value “150” is stored in the RT1 game number counter, and the subtraction is performed through the operation of RT1. As a result, the operation of RT1 ends on condition that the value of the RT1 game number counter is updated to “0”.

  The main CPU 31 performs a bonus operation check process described later with reference to FIG. 26 after S15 or after S16 (S17). It is checked whether or not the bonus operation starts. When this process ends, the process proceeds to S2.

  Next, with reference to FIG. 20, the medal acceptance / start check process will be described. First, the main CPU 31 determines whether or not the automatic insertion counter is 0 (S31). When it is determined that the automatic insertion counter is 0, the medal passage permission is performed (S32). The selector solenoid is driven, and the passage of medals in the selector is prompted.

  When determining that the automatic insertion counter is not 0, the main CPU 31 copies the automatic insertion counter to the insertion number counter (S33). Next, the main CPU 31 clears the automatic insertion counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 31 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 31 determines whether or not the BB gaming state flag is on (S36). When determining that the BB gaming state flag is ON, the main CPU 31 changes the maximum value of the inserted number counter to 2 (S37).

  The main CPU 31 determines whether or not a medal has been detected after S37 or when it is determined in S36 that the BB gaming state flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 31 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the inserted number counter has not reached the maximum value, the main CPU 31 adds 1 to the inserted number counter (S40). Next, the main CPU 31 stores 5 in the effective line counter (S41). Next, the main CPU 31 transmits a medal insertion command to the sub control circuit (S42). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 31 determines in S39 that the inserted number counter is the maximum value, the main CPU 31 adds 1 to the credit counter (S43). The main CPU 31 checks the bet switch after S43, after S42, or when it is determined in S38 that the passage of medals has not been detected (S44). A numerical value corresponding to the bet button is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 31 determines whether or not the insertion number counter has reached the maximum value (S45). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch is on (S46). .

  When determining that the start switch is not on, the main CPU 31 proceeds to S38, whereas when determining that the start switch is on, the main CPU 31 prohibits medal passage (S47). The selector solenoid is not driven, and medals are expelled. When this process ends, the medal acceptance / start check process ends.

  Next, the internal lottery process will be described with reference to FIG. First, the main CPU 31 performs an internal lottery table determination process which will be described later with reference to FIG. 22 (S61). In this process, the internal lottery table, the number of lotteries, etc. are determined according to whether or not the bonus game state is activated and whether or not the RT is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table. For example, when an internal lottery table for a general gaming state is determined, 9 is determined as the number of lotteries.

  Next, the main CPU 31 obtains a random value stored in the random value storage area and sets it as random number data (S62). Next, the main CPU 31 sets the same value as the number of lotteries as a winning number, refers to the internal lottery table, and acquires a lottery value corresponding to the winning number (S63).

  Next, the main CPU 31 subtracts the lottery value from the random number data (S64). Next, the main CPU 31 determines whether or not a digit has been made (S65). When the main CPU 31 determines that the digit is not performed, the main CPU 31 subtracts 2 from the number of lotteries (S66).

  Next, the main CPU 31 determines whether or not the number of lotteries is 0 (S67). When the main CPU 31 determines that the number of lotteries is not 0, the process proceeds to S63. On the other hand, when the number of lotteries is determined to be 0, the main CPU 31 sets 0 as the small role / replay data pointer and bonus data pointer. (S68).

  When the main CPU 31 determines in S65 that a digit has been made, the main CPU 31 obtains the small role / replay data pointer and the bonus data pointer according to the current winning number (S69). After S69 or S68, the main CPU 31 refers to the small winning combination / replay internal winning combination determination table and acquires the internal winning combination based on the small winning combination / replay data pointer (S70).

  Next, the main CPU 31 stores the acquired internal winning combination in the internal winning combination storing area (S71). Next, the main CPU 31 determines whether or not the data stored in the carryover combination storage area is 0 (S72). When the main CPU 31 determines that the data stored in the carryover combination storage area is 0, the main CPU 31 refers to the bonus internal winning combination determination table and acquires the internal winning combination based on the bonus data pointer (S73). ). Next, the main CPU 31 stores the acquired internal winning combination in the carryover combination storing area (S74).

  After determining whether the data stored in the carryover combination storage area is not 0 after S74, the main CPU 31 performs a logical OR operation between the carryover combination storage area and the internal winning combination storage area. Is stored in the internal winning combination storing area (S75). When this process ends, the internal lottery process ends.

  Next, an internal lottery table determination process will be described with reference to FIG. First, the main CPU 31 determines whether or not the BB gaming state flag is on (S91). When determining that the BB gaming state flag is ON, the main CPU 31 sets the RB gaming state internal lottery table and sets 1 as the number of lotteries (S92). When this process ends, the internal lottery table determination process ends.

  When determining that the BB gaming state flag is not on in S91, the main CPU 31 sets the general gaming state internal lottery table and sets 9 as the number of lotteries (S93). Next, the main CPU 31 determines whether or not the data stored in the carryover combination storage area is 0 (S94). When the main CPU 31 determines that the data stored in the carryover combination storage area is not 0, the main CPU 31 subtracts 1 from the number of lotteries (S95).

  The main CPU 31 determines whether or not the RT1 operating flag is ON after S95 or when it is determined that the data stored in the carryover combination storage area is 0 in S94 (S96). When determining that the RT1 operating flag is on, the main CPU 31 refers to the RT1 operating lottery value change table and changes the lottery value assigned to the winning number 6 of the internal lottery table for the general gaming state ( S97). As a result, the winning probability of the internal winning combination “Replay A” increases.

  The main CPU 31 determines whether or not the RT2 operating flag is ON after S97 or when it is determined in S96 that the RT1 operating flag is not ON (S98). When the main CPU 31 determines that the RT2 operating flag is ON, the main CPU 31 refers to the RT2 operating lottery value change table and changes the lottery value assigned to the winning number 7 in the general gaming state internal lottery table ( S99). As a result, the winning probability of the internal winning combination “Replay B” increases.

  The main CPU 31 determines whether or not the RT3 operating flag is ON after S99 or when it is determined in S98 that the RT2 operating flag is not ON (S100). When determining that the RT3 operating flag is not on, the main CPU 31 ends the internal lottery table determination process. On the other hand, when determining that the RT3 operating flag is on, the main CPU 31 determines the RT3 operating lottery value change table. The lottery value assigned to the winning number 8 in the internal lottery table for general gaming state is changed (S101). As a result, the winning probability of the internal winning combination “Replay C” increases. When this process ends, the internal lottery table determination process ends.

  Next, the reel stop control process will be described with reference to FIG. First, the main CPU 31 determines whether or not a valid stop button has been pressed (S111). When the main CPU determines that a valid stop button has not been pressed, it waits until it is pressed.

  When the main CPU 31 determines that a valid stop button has been pressed, the main CPU 31 invalidates the operation of the corresponding stop button (S112). The valid and invalid states of each stop button are managed in a predetermined storage area provided in the main RAM.

  Next, the main CPU 31 refers to the determined stop table and refers to the symbol counter (that is, the symbol position in the middle of the corresponding display window when the stop button is pressed, hereinafter referred to as “stop start position”). ) To obtain stop data (S113). When the rotation of the corresponding reel is stopped, the position of the symbol displayed in the middle of the corresponding display window (or the number of sliding symbols as a difference between the position of the symbol and the stop start position) is temporarily determined.

  Next, the main CPU 31 sets 5 as the number of checks (S114). In the present embodiment, since the maximum number of sliding symbols is “4”, when the stop button is pressed, including the symbol position in the middle of the corresponding display window, Up to the position is subject to check. That is, any of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, the main CPU 31 searches for the position of the symbol having the highest priority among the positions of the symbols within the range of the number of checks including the stop start position based on the internal winning combination (S115). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  In the present embodiment, an internal winning combination (for example, BB + Bell A or BB + Replay A) that allows display of a combination of symbols related to the granting of two or more kinds of benefits, such as when there is a carryover combination “BB”. ) May be determined, but at this time, the position of the symbol with the highest priority is determined according to a predetermined priority. In the present embodiment, the position of the symbol that can display the symbol combination related to the re-game operation is the highest, and the symbol combination that can display the symbol combination related to the bonus game state operation can be displayed. The predetermined priority order is defined so that the position of the symbol that can display the combination of symbols related to the payout of medals is the third highest and the position of the symbol is the third highest.

  Next, the main CPU 31 determines the number of sliding symbols based on the acquired stop data and the search result (S116). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. That is, if the symbol position temporarily determined in S113 is the position of the symbol with the highest priority, the number of symbols up to this symbol position is determined as the number of sliding symbols, while the symbol temporarily determined in S113 is If the position of the symbol different from the position is the symbol position with the highest priority, the number of symbols up to the symbol position is determined as the number of sliding symbols.

  Next, the main CPU 31 shifts to waiting for a scheduled stop position (S117). When moving to the waiting for the planned stop position, the driving of the stepping motor is controlled by an interrupt process described later, and the symbol counter is updated by the number of sliding symbols, that is, the symbol position with the highest priority is displayed. The reels stop rotating after reaching the middle of the window.

  Next, the main CPU 31 transmits a reel stop command to the sub control circuit (S118). The reel stop command includes a parameter for specifying the type of the stopped reel.

  Next, the main CPU 31 determines whether or not there is a stop button whose operation is valid (S119). That is, it is determined whether there is a reel that is still rotating. When the main CPU determines that there is a stop button with an effective operation, the main CPU proceeds to S111, whereas when it determines that there is no stop button with an effective operation, the main CPU ends the reel stop control process.

  Next, the bonus end check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the bonus end number counter is 0 (S151). When determining that the bonus end number counter is 0, the main CPU 31 performs BB end time processing (S152). In this process, the game state flag storage area is cleared, and various counters for managing the bonus end timing are cleared. Next, the main CPU 31 transmits a bonus end time command to the sub-control circuit (S153). Next, the main CPU 31 turns on the RT1 operating flag, the RT2 operating flag, and the RT3 operating flag, and sets the RT1 game number counter to 150, the RT2 game number counter to 100, and the RT3 game number counter to 50, respectively. Set (S154). When this process ends, the bonus end check process ends.

  When the main CPU determines that the bonus end number counter is not 0 in S151, the main CPU decrements the winning possible number counter and the possible gaming number counter by 1 (S155). Next, the main CPU determines whether or not the winning possible number counter and the possible gaming number counter are 0 (S156).

  When the main CPU determines that the winable number counter and the possible game number counter are not 0, the main CPU ends the bonus end check process, whereas when determining that the winning number counter and the possible game number counter are 0, Processing at the end of RB is performed (S157). In this process, the RB gaming state flag is turned off, and the winning possible number counter and the gaming possible number counter are cleared. When this process ends, the bonus end check process ends.

  Next, the RT control process will be described with reference to FIG. First, the main CPU 31 determines whether or not the RT1 operating flag is on (S161). When determining that the RT1 in-operation flag is on, the main CPU 31 decrements the RT1 game number counter by 1 (S162).

  Next, the main CPU 31 determines whether or not the RT1 game number counter is 0 (S163). When determining that the RT1 game number counter is 0, the main CPU 31 turns off the RT1 operating flag (S164).

  After S164, when the main CPU 31 determines that the RT1 operating flag is not on in S161, or determines that the RT1 game number counter is not 0 in S163, whether or not the RT2 operating flag is on Is determined (S165). When determining that the RT2 operating flag is ON, the main CPU 31 decrements the RT2 game number counter by 1 (S166).

  Next, the main CPU 31 determines whether or not the RT2 game number counter is 0 (S167). When it is determined that the RT2 game number counter is 0, the RT2 operating flag is turned off (S168).

  When the main CPU 31 determines that the RT2 operating flag is not on in S165 after S168, or determines that the RT2 game number counter is not 0 in S167, whether or not the RT3 operating flag is on Is determined (S165). When determining that the RT3 operating flag is not on, the main CPU 31 terminates the RT control process, whereas when determining that the RT3 operating flag is on, the main CPU 31 decrements the RT3 game number counter by 1 (S170). .

  Next, the main CPU 31 determines whether or not the RT3 game number counter is 0 (S171). When determining that the RT3 game number counter is not 0, the main CPU 31 ends the RT control process, while when determining that the RT3 game number counter is 0, the main CPU 31 turns off the RT3 operating flag (S172). When this process ends, the RT control process ends.

  Next, the bonus operation check process will be described with reference to FIG. First, the main CPU 31 determines whether or not the display combination is BB (S181). When the main CPU 31 determines that the display combination is BB, the main CPU 31 performs BB operation processing based on the bonus operation table (S182). In this process, the BB gaming state flag is turned on, and a predetermined value “346” is set in the bonus end number counter. Next, the main CPU 31 clears the value of the carryover combination storage area (S183). Next, the main CPU 31 refers to the RT operating flag storage area and turns off all RT operating flags (S184). Next, the main CPU 31 transmits a bonus start command to the sub-control circuit (S185). When this process ends, the bonus operation check process ends.

  When determining that the display combination is not BB in S181, the main CPU 31 determines whether or not the display combination is Replay A, Replay B, or Replay C (S186). When determining that the display combination is Replay A, Replay B, or Replay C, the main CPU 31 copies the value of the insertion number counter to the automatic insertion counter (S187). When this process ends, the bonus operation check process ends.

  When determining that the display combination is not Replay A, Replay B, or Replay C in S186, the main CPU 31 determines whether or not the BB gaming state flag is on (S188). When determining that the BB gaming state flag is not on, the main CPU 31 ends the bonus operation check process. On the other hand, when determining that the BB gaming state flag is on, the main CPU 31 determines whether the RB gaming state flag is on. Is discriminated (S189).

  When determining that the RB gaming state flag is on, the main CPU 31 ends the bonus operation check process. On the other hand, when determining that the RB gaming state flag is not on, the main CPU 31 determines whether the RB gaming state flag is on based on the bonus operating time table. Processing is performed (S190). In this process, the RB gaming state flag is turned on, and a predetermined value “8” is set in the winning possible number counter and the possible gaming number counter. When this process ends, the bonus operation check process ends.

  Next, an interrupt process (1.1173 msec) controlled by the main CPU will be described with reference to FIG. First, the main CPU 31 saves the register (S201). Next, the main CPU 31 performs input port check processing (S202). In this process, signals input from various switches such as a stop switch are checked.

  Next, the main CPU 31 performs a reel control process (S203). In this process, when the start of rotation of all the reels is requested, the driving of the stepping motor is controlled so that the rotation of each reel is started and then rotated at a constant speed. When the number of sliding pieces is determined, the driving of the stepping motor is controlled so that the rotation of the corresponding reel waits for the number of sliding pieces and the rotation is decelerated and stopped.

  Next, the main CPU 31 performs a lamp and 7-segment driving process (S204). Next, the main CPU 31 restores the register (S205). When this process ends, the interrupt process ends.

  Next, with reference to FIG. 28, a time chart regarding the operation of RT will be described.

  First, on the condition that the operation of BB is completed, the operation of RT1, the operation of RT2, and the operation of RT3 are started. When the operation of RT1 is performed, the lottery value “8980” when the internal winning combination “Replay A” defined by the internal lottery table for the general gaming state is determined is larger than this value “17690”. Is changed.

  Further, when the operation of RT2 is performed, the lottery value “1” when the internal winning combination “Replay B” defined by the internal lottery table for the general gaming state is determined is a value larger than this. It is changed to “17690”. Further, when the operation of RT3 is performed, the lottery value “1” when the internal winning combination “Replay C” defined by the internal lottery table for the general gaming state is determined is a value larger than this. It is changed to “17690”.

  Then, when the number of games counted after the operation of BB has reached 50, the operation of RT3 is ended first. When the operation of RT3 is completed, the lottery value when the internal winning combination “Replay C” is determined is changed from the value “17690” after the change to the value “1” before the change specified by the internal lottery table for the general gaming state. Return to. At this time, since the operation of RT1 and the operation of RT2 are continuously performed, the lottery value when the internal winning combination “Replay A” is determined and the lottery value when the internal winning combination “Replay B” is determined. The value “17690” after the change is inherited.

  Subsequently, when the number of games counted after the operation of BB has reached 100, the operation of RT2 is ended. When the operation of RT2 is completed, the lottery value when the internal winning combination “Replay B” is determined is changed from the value “17690” to the value “1” before the change defined by the internal lottery table for the general gaming state. Return to. At this time, since the operation of RT1 is continued, the changed value “17690” is taken over as the lottery value when the internal winning combination “Replay A” is determined. Further, since the operation of RT3 has already ended, the lottery value when the internal winning combination “Replay C” is determined is the value “1” defined in the internal lottery table for the general gaming state.

  Subsequently, when the number of games counted after the operation of BB has reached 150, the operation of RT1 is ended. When the operation of RT1 ends, the lottery value when the internal winning combination “Replay A” is determined is changed from the value “17690” after the change to the value “8980 before the change defined by the internal lottery table for the general gaming state. Return to. Since the operation of RT2 and the operation of RT3 have already ended, the lottery value when the internal winning combination “Replay B” is determined and the lottery value when the internal winning combination “Replay C” is determined are respectively The value is “1” defined in the internal lottery table for the general gaming state.

  Thus, according to the pachi-slot 1 of the present embodiment, as in the prior art, when a dedicated internal lottery table is defined according to each RT, and all replays are determined according to the operation of each RT The lottery value is not reset uniformly, but only the lottery value when a specific replay is determined for each RT by referring to the common internal lottery table (general gaming state internal lottery table) for each RT. By changing each of them separately, the winning probability of replay was changed. As a result, it is possible to give a variety of flexibility and flexibility while reducing the control burden and the like without increasing the operating conditions of the RT.

  In addition, by ending the operation of each RT on the condition that different number of games are counted in each, the lottery value when each replay is determined is individually returned to the one before the change, and the operation is performed. For continued RT, the changed lottery value can be inherited as it is. Therefore, when returning the winning probability of one replay from the state of changing the winning probability of multiple replays while returning the winning probability of another replay to the one before the change, the operation of each RT is changed. It is only necessary to finish the process, and it is not necessary to provide a new condition and a new internal lottery table. As a result, it is possible to give various versatility with elasticity while suppressing an increase in control burden.

  As mentioned above, when referring to a more detailed configuration, the probability of replay unique to each RT varies greatly during the operation of each RT, so that the fixed number of games is counted after the operation of the BB is completed. In the process where each RT is finished, it is possible to add a game such that the winning probability of replay gradually decreases.

  Therefore, compared with the case where the winning probability of replay is reduced at a time, it is possible to prevent the player's expectation from being significantly lowered, and to improve the interest of the game. In addition, the relatively early time after the operation of the BB is relatively high, the higher the probability of winning in the entire replay, and it becomes possible to further reduce the consumption of medals. BB "will be determined.

  Subsequently, the contents of a program executed by the sub CPU 81 of the sub control circuit will be described with reference to FIGS. 29 to 32.

  First, the main board communication task performed by the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 performs a reception check on the command transmitted from the main control circuit (S301). Next, when receiving a command, the sub CPU 81 extracts the type of the command (S302).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S303). If the sub CPU 81 determines that a command different from the previous command has not been received, the process proceeds to S301. On the other hand, if the sub CPU 81 determines that a command different from the previous command has been received, the sub CPU 81 stores the command in the message queue (S304).

  Next, with reference to FIG. 30, an effect registration task performed by the sub CPU 81 will be described. First, the sub CPU 81 extracts a message from the message queue (S311). Next, the sub CPU 81 determines whether there is a message (S312).

  When the sub CPU determines that there is a message, it copies the game information from the message (S313). For example, various data such as an internal winning combination, a type of reel that has stopped rotating, a display combination, an operating flag, and the like specified by parameters are copied to a storage area provided in the sub-RAM.

  Next, the sub CPU 81 performs an effect content determination process which will be described later with reference to FIG. 31 (S314). In this process, depending on the type of the received command, the contents of the effect are determined and the effect data is registered.

  The sub CPU 81 registers animation data after S314 or when it is determined that there is no message in S312 (S315). Next, the sub CPU 81 registers sound data / ramp data (S316). The registration of the animation data, the registration of the sound data, and the registration of the ramp data are performed based on the effect data registered in the effect content determination process. When this process ends, the process proceeds to S311.

  Next, with reference to FIG. 31, a flowchart of the effect content determination process executed by the sub CPU will be described. First, the sub CPU 81 determines whether or not it is a start command reception time (S321). When it is determined that the start command is received, the sub CPU performs an effect lottery process which will be described later with reference to FIG. 32 (S322). In this process, the effect data is determined according to the type of bonus gaming state in which the operation is performed, the type of RT, and the like. The effect data is data that designates animation data, sound data, and lamp data.

  If the sub CPU 81 determines in S321 that the start command is not received, the sub CPU 81 determines whether or not the reel stop command is received (S323). When determining that the reel stop command is received, the sub CPU 81 sets the effect data according to the type of the operation stop button or the like (S324).

  Next, when determining that the reel stop command is not received, the sub CPU 81 determines whether or not the display command is received (S325). When the sub CPU 81 determines that the display command is being received, the sub CPU 81 sets the effect data according to the type of display combination or the like (S326).

  Next, when determining that the display command is not received, the sub CPU 81 determines whether or not the bonus start command is received (S327). When the sub CPU 81 determines that the bonus start command is received, the sub CPU 81 sets the BB start effect data (S328).

  Next, when determining that the bonus start command is not received, the sub CPU 81 determines whether or not the bonus end command is received (S329). When the sub CPU 81 determines that the bonus end command is not received, the sub CPU 81 ends the effect content determination process. On the other hand, if the sub CPU 81 determines that the bonus end command is received, the sub CPU 81 sets the BB end effect data ( S330).

  The sub CPU 81 requests registration of the set effect data after S322, S324, S326, S328, or S330 (S331). When the effect data is registered, corresponding animation data and the like are determined, and effects such as video display are executed. When this process ends, the effect content determination process ends.

  Subsequently, a flowchart of the effect lottery process will be described with reference to FIG. First, the sub CPU 81 determines whether or not it is in the BB gaming state (S351). When determining that the sub CPU 81 is in the BB gaming state, the sub CPU 81 sets the effect data for BB operation (S352). When this process ends, the effect lottery process ends.

  When the sub CPU 81 determines in S351 that the BB gaming state is not set, it determines whether or not the RT1 operating flag is ON (S353). When the sub CPU 81 determines that the RT1 operating flag is not on, the sub CPU 81 refers to the general gaming state effect determination table and determines the effect data based on the internal winning combination (S354). As shown in FIG. 28, since the operation of RT1 continues for the longest time in each RT, when the operation of RT1 is completed, the operations of other RTs are already completed. The period in which each RT is not operated is a period in which the winning probability of the entire replay is the lowest since the winning probability of replay unique to each RT is not high. When this process ends, the effect lottery process ends.

  When determining that the RT1 operating flag is on in S353, the sub CPU 81 determines whether or not the RT2 operating flag is on (S355). When the sub CPU 81 determines that the RT2 operating flag is not ON, the sub CPU 81 refers to the RT operating (low) effect determination table and determines the effect data based on the internal winning combination (S356). Since the operation of RT2 continues longer than the operation of RT3, when the operation of RT2 is finished, the operation of RT3 is already finished. The period in which only the operation of RT1 is performed is the period in which the winning probability of the entire replay is the third highest because only the winning probability of Replay A unique to RT1 is high. When this process ends, the effect lottery process ends.

  When determining that the RT2 operating flag is on in S355, the sub CPU 81 determines whether or not the RT3 operating flag is on (S357). When the sub CPU 81 determines that the RT3 operating flag is not ON, the sub CPU 81 refers to the RT operating (medium) effect determination table and determines the effect data based on the internal winning combination (S358). During the period in which the operation of RT1 and the operation of RT2 are performed, the winning probability of Replay A inherent to RT1 and the winning probability of Replay B inherent to RT2 are high, so the winning probability of the entire replay is second. It is a high period. When this process ends, the effect lottery process ends.

  When determining that the RT3 operating flag is ON in S357, the sub CPU 81 refers to the RT operating (high) effect determining table and determines the effect data based on the internal winning combination (S359). The period during which all RTs are operated is the period in which the winning probability of the entire replay is the highest since the winning probability of replay unique to each RT is high. When this process ends, the effect lottery process ends.

  Although the present embodiment has been described above, the present invention is not limited to this. That is, the reel, random number extraction means, internal lottery means, reel rotation means, stop operation detection means, reel stop means, re-game operation means, bonus operation means, game count counting means, probability variation, provided in the gaming machine of the present invention Specific configurations of the state actuating means, the first changing means, the second changing means, the third changing means, the first probability variation state ending means, the second probability variation state ending means, the third probability variation state ending means, etc. are described above. However, the present invention is not limited to each element of this embodiment.

  In the present embodiment, it is adopted that the operation of the bonus game state (BB) is completed as a predetermined condition, and each RT is operated when this condition is satisfied. It is not limited. For example, each RT may be operated on condition that a combination of specific symbols is displayed by a plurality of reels. Specific symbol combinations include, for example, symbol combinations related to replay operations, symbol combinations related to paying out medals such as “Cherry” and “Bell A”, and “Bell-Cherry-Cherry”. You may make it employ | adopt the combination of the symbol which concerns. For example, when the combination of symbols “Bell A” is adopted, S154 of the bonus end check process shown in FIG. 24 is omitted, and “is the display combination Bell A?” Before S188 of the bonus operation check process shown in FIG. To determine the content of "." Then, when it is determined that the bell is A, the same processing as in the above S154 is performed.

  In this embodiment, three types of replay A, replay B, and replay C are provided as internal winning combinations related to the replay operation, and three types of RTs that vary the winning probability according to each replay are provided. However, the present invention is not limited to this, and the type can be arbitrarily changed. For example, the internal symbol combination “Replay D” that permits display of the fourth symbol combination (for example, chance-chance-replay) related to the replay operation and the lottery value when this is determined are individually changed. A configuration may be adopted in which a fourth RT is provided and the operation is terminated by counting the number of games (for example, 25 times) different from the number of games at which the other RTs are terminated. In this way, by increasing the number of types of replays that each change individually, and by varying the number of games that triggers the end of each replay change, the stage in which the winning probability of replay is reduced is detailed. Since it can be set, it is preferable that the expectation of the player is not significantly lowered and the interest of the game is improved.

  In the present embodiment, “150” is adopted as the first number of times that triggers the end of the first RT operation, and “second” number of times that triggers the end of the second RT operation. “100” is adopted, and “50” is adopted as the third number of times to end the operation of the third RT. However, the present invention is not limited to this, and the number of times can be arbitrarily changed. is there.

  Further, in the present embodiment, the internal lottery table shown in FIG. 10 is adopted as a data table for defining a random value when each of a plurality of types of internal winning combinations is determined, and each of the plurality of types of internal winning combinations is determined. Although the above-mentioned lottery value is adopted as the random number value when the value is determined, the present invention is not limited to this. For example, the internal lottery table defines a range of random values (for example, a lower limit value and an upper limit value) when each of a plurality of types of internal winning combinations is determined, and the extracted random value is within the above range Alternatively, a method of determining a corresponding internal winning combination may be adopted.

  In this case, for example, if the range of the random number value when the replay A is determined in the internal lottery table for the general gaming state is defined as “0 to 8979”, this range “0 to 27305” is further increased during the operation of RT1. By changing to a small range “0 to 17689”, the winning probability of Replay A can be changed as in the case of changing the lottery value described above.

  Further, in the present embodiment, the internal lottery table is referred to, the data pointer is temporarily determined based on the extracted random number value, and then the internal winning combination determination table is referred to and the internal winning combination corresponding to the data pointer is determined. However, the present invention is not limited to this. The internal winning combination may be determined without going through the determination of the data pointer. That is, the internal lottery table may adopt a configuration that defines an internal winning combination consisting of 1 byte instead of the data pointer corresponding to the winning number.

  In the present embodiment, a lottery value change table that defines the winning number to be changed and the lottery value after the change is provided, and the lottery value is changed with reference to the lottery value. It is not always necessary to provide a change table. For example, the content of S97 of the internal lottery table determination process shown in FIG. 22 may be changed to the content of “change the lottery value of the winning number 7 of the internal lottery table for general gaming state to 17690”.

  The device configuration shown in FIGS. 1 to 2, the circuit configuration and peripheral devices shown in FIGS. 3 and 4, the table configuration shown in FIGS. 5 to 14, and the table configuration shown in FIGS. The configuration of the RAM storage area, the configuration of the flowcharts shown in FIGS. 19 to 32, and the like can be arbitrarily changed or modified without departing from the spirit of the present invention.

  In addition to the slot machine (cylinder-type game machine) provided with the mechanical reel as in this embodiment, the present invention is also applied to a game machine such as a video slot that displays the reels and symbols arranged on the surface thereof by video. The invention can be applied. Furthermore, a game can be executed by applying the present invention to a game program in which the operation in the slot machine is executed in a pseudo manner for a home game machine. In that case, a CD-ROM, FD (flexible disk), or any other recording medium can be used as a recording medium for recording the game program.
