Abstract

<P>PROBLEM TO BE SOLVED: To provide a technique capable of providing a novel gaming property enhancing the amusement of a player using the function of fluctuating winning probability of a replay winning combination. <P>SOLUTION: The replay winning combination is preferentially established when winning overlap winning combinations when winning the overlap winning combinations by winning at least a part of the replay winning combinations as the overlap winning combinations. The winning probability of the replay winning combinations won as the overlap winning combinations is set lower than in the ordinary game condition when replay probability fluctuating condition (RT game) occurs. Thus, other game winning combinations constituting the overlap winning combinations with the replay winning combinations are rarely established in the ordinary game condition but easily established during an RT game. The player can feel as though the condition would be shifted to the special game condition where the game winning combinations being rarely established in a usual condition are established, so that the amusement to the game can be effectively enhanced. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a rotating cylinder for performing a game in which a predetermined game combination is established by rotating a plurality of rotating cylinders having a plurality of types of symbols displayed on the outer peripheral surface and combining the symbols when the plurality of rotating cylinders are stopped. It relates to a type game machine.

  2. Description of the Related Art A spinning-type gaming machine that performs a game in which a plurality of spinning cylinders on which a plurality of types of symbols are drawn is rotated to stop each spinning cylinder so as to obtain a predetermined combination of symbols is widely known. In such a spinning machine, first, when a game medal is bet and the start lever is operated, all the spinning cylinders start to rotate, and an internal lottery is performed in advance to establish which game combination is established. It is decided whether or not to establish. After that, when the player operates the stop button of each torso to stop each torso, and a combination of symbols that establishes the winning game player in the internal lottery is obtained, a game medal corresponding to the game player is obtained. Will be paid out. In addition, there is a special game player called “re-game player” among the game players, and when the re-game player is established, it is possible to start the next game without betting a game medal. It has become.

  In such a spinning-type game machine, the winning probability of the re-gamer can be changed, and the game state in which the probability of winning the re-gamer is set higher than usual (hereinafter, this game state is indicated as A gaming machine provided with a replay time game or simply called an RT game has also been proposed (Patent Document 1). When this RT game is started, there is a high possibility that a re-gamer will be established, and game players other than the re-gamer may also be established, so that the game can be played without reducing game medals compared to the normal game state. It is possible to continue.

JP 2005-31659 A

  However, during RT games, although it is advantageous for the player in that the game can be played without reducing the game medals so much, the winning probability of the game players other than the re-game player does not change, so only the re-game player is established. There is a problem that the game tends to be monotonous and the interest of the player may be reduced.

  The present invention has been made in order to solve the above-described problems in the prior art, and provides a new gameability that enhances the interest of the player by using the function of changing the winning probability of the re-gamer. The purpose is to provide technology that can be used.

In order to solve at least a part of the above-described problems, the rotating game machine of the present invention employs the following configuration. That is,
After a game medium is inserted, when a plurality of types of symbols on which a plurality of types of symbols are drawn are rotated, and when the plurality of types of cylinders are stopped, a combination of symbols that establish a predetermined game combination is prepared. In a spinning-type gaming machine that performs a game in which a predetermined privilege is given to the player according to the established game player,
As the predetermined game player, a game player storage means for storing a plurality of types of game players including a re-game player capable of starting the next game without inserting the game medium,
A lottery is performed as to which of the plurality of types of gaming actors is to be established, and at least a part of the re-gaming actors, a gaming actor lottery means for winning a duplicate role together with other gaming actors;
Re-game priority in which, when a winning combination of the re-gamer and the other gamer is won by lottery by the gamer lottery means, the re-gamer is given priority over the other gamer. Winning means,
Re-game probability variation state starting means for starting a re-game probability variation state in which the winning probability of the re-player is different from the normal game state,
The re-playing probability variation state starting means starts the re-playing probability variation state in which a winning probability of a re-playing role to be won as the duplicate combination is set lower than a normal gaming state.

  In such a swivel-type gaming machine of the present invention, at least one of the re-game players is determined by performing a lottery as to which game player is to be established from among a plurality of types of game players or which game player is not to be established. With respect to the division, winning as a duplicate combination with other game combinations is established, and when this duplicate combination is won, a re-game combination is given priority over other game combinations. Then, in the re-game probability variation state, the winning probability of the re-game player to be won as a duplicate role (duplicate re-game character) is set lower than that in the normal game state. Here, “at least a part of the re-gamer” may be all or part of the winning area (for example, the width of the random value) of the re-gamer by lottery. In addition, even if the winning area of the re-gamer is divided and provided, it is regarded as the same re-gamer, and “at least a part of the re-gamer” is all or a part of the winning area of the entire re-gamer And

  By doing so, it is possible to effectively excite the player's interest in games for the following reasons. First, in a normal gaming state, even if a duplicate combination is won, a re-playing combination is preferentially established. Therefore, for other game combinations won as a duplicate combination, the winning combination is not won or the winning probability is kept low. It has been. On the other hand, in the re-playing probability variation state, the winning probability of the duplicate re-playing combination is lowered, and accordingly, the probability that the other gaming combination constituting the overlapping combination is won alone is increased. In other words, since it becomes easy for a player who does not win in the normal gaming state or rarely wins, it feels to the player that a new gaming state has started. Eventually, despite the fact that one of the duplicate roles is set as a replay role, and the replay probability fluctuation state is reached, the simple control of lowering the winning probability of the replay role is performed. It is possible to give the player an impression that the player has switched to a special game state in which a player who does not win (or rarely does not win) in the game state wins, and can greatly increase the interest in the game.

  In such a gaming machine, it is assumed that a plurality of ratios for lowering the winning probability of the duplicate re-gamer than the normal game state are set. It is good also as lowering the winning probability.

  In this way, if it is set so that the winning probability of the duplicate re-gamer in the re-playing probability variation state can be varied (decreased) in multiple stages, the gameability in the re-play probability variation state can be varied. Can do. That is, if the winning probability of a duplicate re-gamer is greatly reduced, the probability of winning a prize for another game player that constitutes a duplicate role with the re-game player increases, and conversely, the win probability of a duplicate re-game player is not much. If not reduced, the winning probability of other game actors constituting the duplicate combination does not become so high, so that it is possible to change the player's expectation with respect to the re-game probability fluctuation state. As a result, it is possible to greatly enhance the interest of the player in the game.

  In addition, in such a revolving game machine, in addition to the duplicate re-gamer, a re-game player to be elected alone (single re-game player) is provided. The winning probability may be set to be lower than that in the normal gaming state, and the winning probability that is a combination of the duplicate replaying role and the single replaying role may be set to be higher than that in the normal gaming state.

  In this way, when the re-gaming probability variation state is reached, a gaming role constituting an overlapping role with the re-gaming role can be won, and the probability that the re-gaming role wins is higher than in the normal gaming state. In general, it is advantageous for a player to be able to play a game without reducing game media if the probability of winning a re-gamer is set high. However, only the re-gamer is established and the game is monotonous. It tends to become. However, at the same time as the probability of winning a re-gamer is increased, it is possible to avoid a monotonous game if a player who does not win in a normal game state or rarely wins a game player wins. As a result, it is possible to effectively enhance the interest of the player in the game.

  Furthermore, in such a swivel type gaming machine, it is assumed that a single bonus (SB) role that gives a privilege more advantageous to the player than a normal game player is provided. It is good also as letting you win as a duplicate role with a role.

  In this way, if the SB combination is set as a duplicate combination with the re-playing role, the SB role that is not won (or rarely won) in the normal gaming state becomes the re-playing probability variation state. It will be easier to win. Here, the SB combination is a game combination to which a privilege that is more advantageous to the player than the normal game combination is given if a prize is won. When the re-playing probability variation state is entered, the game shifts to a game in which a relatively large number of SB roles are established, so that it is possible to give the player an impression that the player has switched to a special gaming state that is set to be very advantageous for the player. it can. Further, since a relatively large number of SB combinations are established, the player can increase the number of game medals in the re-game probability fluctuation state.

  In addition, the winning probability of the re-playing role in the normal gaming state is not set so high, and the SB role that is won as an overlapping role with the re-playing role (or part thereof) in the normal gaming state is Even if it becomes possible to win in the game probability fluctuation state, the winning probability of the SB role is not so high. Therefore, even if the SB combination is set as a duplicate combination with the re-game combination, the gambling of the game does not become too high.

A-2. Electrical configuration:
FIG. 4 is an explanatory diagram showing an electrical configuration of the gaming machine 1 according to the present embodiment. As shown in FIG. 4, the gaming machine 1 includes a main control board 200 and a sub-control board 220, a door board 240, a rotating board 260, a power board 280, and the like that are connected to exchange data. ing.

  The main control board 200 is a board that manages the progress and production of the entire game performed in the gaming machine 1. The main control board 200 is mounted with a CPU, ROM, RAM, etc. connected to each other via a bus so that data can be exchanged with each other. The start lever 36 is operated from the door board 240 mounted on the front door 2. These signals are output to the sub-control board 220, the door board 240, the rotor board 260, and the like while executing a game control process to be described later. Controls the operation of various substrates.

  Similarly to the main control board 200 described above, the sub control board 220 is configured by connecting a CPU, a ROM, a RAM, and the like so as to exchange data with each other via a bus. In addition, various lamps 12, various speakers 14 and 114, the effect display device 10, a rotating backlight 20 </ b> L, and the like are connected to the sub control board 220. Here, the spinning cylinder backlight 20L is a light that is provided inside each spinning cylinder 20a, 20b, 20c and illuminates the pattern (see FIG. 3) drawn on the surface of the spinning cylinder from the back side. The sub control board 220 analyzes the control command received from the main control board 200, and outputs drive signals to the various lamps 12, the various speakers 14, 114, the effect display device 10, and the rotary backlight 20L, respectively. Various performances are performed.

  On the door board 240, the medal selector 106, various insertion buttons 32 and 34 for inserting the stored game medals, the start lever 36 for starting the rotation of the rotating drum, and the rotating rotating drum are stopped. Crotch stop buttons 38a, 38b, 38c for causing the game to be completed, a settlement button 40 for paying out the stored game medals or the inserted game medals and ending the game, various display panels 22 for displaying the game status, etc. Is connected. The door board 240 is connected to the main control board 200 described above so as to exchange data. For this reason, when the start lever 36 provided on the front door 2, the rotating cylinder stop buttons 38 a, 38 b, 38 c, various input buttons 32, 34, the adjustment button 40, etc. are operated, the signal is transmitted via the door substrate 240. Can be supplied to the main control board 200. Further, a signal that the medal selector 106 detects the passage of the game medal by the built-in medal sensor is also supplied to the main control board 200 through the door board 240.

  On the rotating board 260, the rotating motors 24a, 24b, 24c for rotating the three rotating cylinders 20a, 20b, 20c, respectively, and the rotating sensors 26a, 26b for detecting the rotational positions of the respective rotating cylinders. , 26c. The rotating substrate 260 detects the rotational positions of the rotating cylinders 20a, 20b, and 20c by the rotating sensors 26a, 26b, and 26c, and drives the rotating motors 24a, 24b, and 24c, thereby rotating the rotating cylinders 20a. , 20b, 20c can be stopped at a desired rotational position. In the gaming machine 1 of this embodiment, so-called stepping motors are used for the spinning motors 24a, 24b, and 24c.

  The medal payout device 118 is connected to the main control board 200 via a relay board (not shown), and performs an operation of paying out a predetermined number of game medals based on a control signal from the main control board 200.

  These various control boards and power consumed by the boards are supplied from a power supply board 280. An AC voltage of 100 V is supplied to the power supply board 280, and this electric power is converted into a DC voltage of a specified voltage and then supplied to each control board and board. In FIG. 4, a state in which power is supplied from the power supply board 280 is represented by a dashed arrow.

B. Overview of the game:
In the following, the contents of the control performed in order to advance the game in the rotary type gaming machine 1 having the above-described configuration will be described, but as an preparation, an outline of the game performed in the rotary type gaming machine will be described. Keep it.

  In starting the game, a game medal is inserted from the game medal slot 30 and a medal bet is placed. The number of game medals to bet is usually fixed to one or three. If game medals are stored in advance as credits, it is possible to bet 1 or 3 game medals by pressing the 1-sheet insertion button 32 or the 3-sheet insertion button 34, respectively. is there.

  When a game medal is bet and the start lever 36 is operated, the three spinning cylinders 20a, 20b, and 20c start rotating all at once. As described above with reference to FIG. 3, a plurality of symbols are drawn on each of the spinning cylinders. Therefore, when the rotating cylinder rotates, these symbols are variably displayed on the display window 20. Further, as described above with reference to FIG. 1, on the front side of the front door 2, three turning stop buttons 38 a, 38 b, 38 c are provided corresponding to the respective turning cylinders. When the rotating cylinder stop buttons 38a, 38b, 38c are pressed while the rotating cylinders 20a, 20b, 20c are rotating, the rotating cylinders corresponding to the pressed buttons stop rotating, and accordingly, the symbols that are displayed in a variable manner are displayed. Stopped display with any of the symbols. When the rotation of the three spinning cylinders 20a, 20b, and 20c is stopped in this way, any symbol is stopped and displayed on each of the spinning cylinders, and some symbol combinations are obtained.

  If the symbol combination thus obtained is a combination that establishes a so-called “small role”, a number of game medals corresponding to the established game role are paid out.

  In addition, the game combination is provided with a game combination called “re-play game combination”. If the combination of symbols obtained when the spinning cylinder stops is a combination that establishes a “re-game”, no game medals will be paid out, but the player will not insert any game medals. The game can be started again. In the gaming machine 1 of this embodiment, a special game state called a replay time (RT) game is set. During the RT game, since the probability that the re-game is established is changed, the re-game is established with a probability different from the normal game state.

  Further, the game combination is provided with a so-called “bonus combination”, and the gaming machine 1 according to the present embodiment includes “regular bonus combination (hereinafter referred to as RB combination)”, “big bonus combination ( In the following, three types of bonus combinations, “BB combination” and “single bonus combination (hereinafter, SB combination)” are set. When the combination of symbols obtained when the three cylinders 20a, 20b, and 20c are stopped is a combination of symbols that establishes the RB role, a gaming state called an RB game that is advantageous to the player is started. The An RB game is a game in which the types of game combinations (types of symbol combinations from which game medals are paid out) increase compared to normal games, and the increased game combinations (increased combinations) are established with a high probability. In the gaming machine 1 of the present embodiment, during the RB game, the above-mentioned “re-gamer” becomes an increasing role, and when the “re-gamer” is established, a predetermined number (15) of game medals are paid out. It has become. This RB game ends when a predetermined number of games are played (for example, 12 games) or when a predetermined number of times a prize is established for the increased number of game players (for example, 8 times). In the case of a combination of symbols that establishes the BB combination, a BB game that is a more advantageous game state for the player than the RB combination is started. The BB game is composed of an introductory game until the RB combination is established and an RB game executed when the RB combination is established, and a predetermined number (for example, 465) of game medals are paid out during the BB game. Until it is played, it is possible to play “RB game” a plurality of times. Furthermore, when a combination of symbols that establishes the SB combination is obtained, a gaming state called SB gaming is started. The SB game is a game corresponding to one game of the above-mentioned RB game, and ends in a short period (one game). However, as with the RB game, an increasing role (in this embodiment, “re-playing game”) Is established with a high probability, and a predetermined number (15) of game medals are paid out, which is a game state advantageous to the player.

  FIG. 5 is an explanatory diagram illustrating various game combinations set in the gaming machine 1 of this embodiment and combinations of symbols that establish these game combinations. As shown in the figure, combinations of three “Red Seven” symbols and combinations of three “Blue Seven” symbols are set as the symbol combinations that establish the BB combination. The combination of symbols for establishing the RB combination is set to a combination of three “bar” symbols. The combination of symbols that establishes the SB combination is set to a symbol whose leftmost symbol is “cherry”. As a combination of symbols for establishing the small role, a combination of three “tin” symbols or a combination of three “watermelon” symbols is set. Furthermore, the combination of symbols for establishing a re-game is set to a combination of three “re-game” symbols. FIG. 5 also displays the number of game medals to be paid out when these game combinations are established in the normal game. Note that a small role established with the symbol “tin” may be referred to as a “small tin character”, and a small character established with the symbol “watermelon” may be referred to as a “watermelon small character”. In addition, the “re-playing combination” is sometimes referred to as a “re-playing combination”. However, in this specification, in order to avoid confusion with the replay time (RT), the “re-playing combination” is exclusively referred to as a “re-playing combination”.

  As described above, in the spinning cylinder type gaming machine 1, after rotating the spinning cylinders 20a, 20b, and 20c simultaneously by betting game medals and operating the start lever 36, the spinning cylinder stop button 38a , 38b, 38c are pressed to stop the rotation of the rotating drum. Depending on the combination of symbols obtained at that time, a game medal is paid out or the game progresses while switching to an advantageous game state. Since the most amount of game medals can be obtained when the BB combination is established, the player continues the game while always wishing to establish the BB combination.

  The progress of such a game is controlled by the main control board 200. Below, the processing content which the main control board 200 is performing in order to control progress of a game is demonstrated.

C. Overview of control:
FIG. 6 is a flowchart showing the first half of the game control process performed by the main control board 200 for controlling the progress of the game in the gaming machine 1 of the present embodiment. FIG. 7 is a flowchart showing the second half of the game control process performed by the main control board 200 in the gaming machine 1 of this embodiment. This game control process is executed after the gaming machine 1 is turned on and after initialization processes such as a thumb check of the ROM mounted on the main control board 200 and the sub control board 220 and a clearing of the RAM are performed. Process.

  As shown in FIG. 6, when the game control process is started, it is first determined whether or not a game medal has been inserted (or betted) (step 100. Hereinafter, step is abbreviated as “S”). If no game medal has been inserted (S100: no), the player enters a standby state while repeating this determination until the insertion is confirmed. When a game medal is inserted (S100: yes), a game can be started.

  When the game can be started, the main control board 200 determines whether or not the start lever 36 has been operated (S102). When the start lever 36 is not operated (S102: no), the process waits until the start lever 36 is confirmed to be operated. When the start lever 36 is operated (S102: yes), the internal lottery process is started (S104). Although details of the internal lottery process will be described later, in this process, a process of determining whether or not the establishment of the game combination described above with reference to FIG. Note that this lottery relates to whether or not a game combination is permitted, and just because a lottery is won, the corresponding game combination is not established immediately. In order to actually establish the winning game combination, the selected game combination is established by pressing the rotation stop buttons 38a, 38b, 38c at an appropriate timing in accordance with the rotation of the rotation cylinders 20a, 20b, 20c. It is necessary to arrange the combinations of symbols to be made. On the other hand, no matter how the rotation stop button 38a, 38b, 38c is pressed at an appropriate timing, the combination of symbols for establishing a game combination is not prepared unless the winning is made in the internal lottery process. . Therefore, the winning in the internal lottery process is only the state of being won internally, and in this sense, the lottery is called “internal” lottery, and the state won internally by the internal lottery is called “internal” winning. .

  The internal lottery process is performed by the main control board 200 in the game control process, and the lottery result is stored in a RAM (not shown) mounted on the main control board 200 (see FIG. 13A). See Furthermore, the type of game combination and the combination of symbols that establish the game combination are stored in advance in a ROM (not shown) mounted on the main control board 200. Therefore, the main control board 200 of this embodiment constitutes one aspect of the “game combination lottery unit” and the “game combination storage unit” in the present invention.

  The main control board 200 starts the rotation rotation starting process following the internal lottery process (S106). In the rotation rotation starting process, it is determined whether or not a predetermined condition is satisfied. If the condition is satisfied, a process of rotating the three rotation cylinders 20a, 20b, and 20c is performed. In the rotation rotation start processing of this embodiment, when the start lever 36 is operated and a predetermined time (for example, 4.1 seconds) has elapsed since the rotation of the rotation cylinders 20a, 20b, and 20c was started last time. As the rotation of the rotating cylinder is started, a drive signal is output to the rotating cylinder motors 24a, 24b, and 24c provided in the respective rotating cylinders 20a, 20b, and 20c, so that the three rotating cylinders 20a, 20b, and 20c are output. Rotate.

  After the three spinning cylinders 20a, 20b, and 20c are thus rotated, the main control board 200 next performs a process for stopping the rotation of the spinning cylinder (rotating cylinder rotation stopping process) (S108). The details of the rotation rotation stop process will be described later. In this process, the rotation stop button 38a, 38b, 38c is pressed according to the result of the internal lottery and the result of the internal lottery. A process for stopping the three cylinders 20a, 20b, and 20c at appropriate positions is performed.

  When the rotation of the three cylinders 20a, 20b, and 20c stops, the main control board 200 determines whether or not a winning is achieved (S110). Here, “winning” means that after winning a game combination by internal lottery, the symbol combinations that establish the game combination are displayed on the active line. As will be described later, in the gaming machine 1 of the present embodiment, the display window 20 is provided with a plurality of effective lines. Note that the establishment of a game combination with symbols on the active line is sometimes simply referred to as winning a game combination. As described above, even if a game combination is won in the internal lottery process (S104), depending on the timing at which the spinning cylinder stop buttons 38a, 38b, 38c are pressed, the symbol combinations corresponding to the game combination are aligned on the active line. Not necessarily. Therefore, the main control board 200 determines whether or not the game combination won by the internal lottery has been won after stopping the rotation of the spinning cylinder.

  FIG. 8 is an explanatory diagram illustrating an effective line set in the gaming machine 1 of the present embodiment. When all the rotating cylinders 20a, 20b, and 20c are stopped in the above-described rotating cylinder rotation stopping process (S108), three symbols (upper, middle, and lower) are displayed on the display window 20 for each rotating cylinder. Nine symbols are stopped and displayed. As shown in the figure, there are three effective lines in the horizontal (upper (L2), middle (L3), and lower (L4) lines, a diagonally upward line (L1), and a lower right line. A total of five diagonal lines (L5) are set. When a symbol combination that establishes a game combination is arranged on any of these five lines, the game combination is established. If it is determined that the game has not been won (S110: no), the game ends, and the process returns to the beginning of the game control process of FIG. 6 and remains in a standby state until a game medal is inserted (or bet). Become. When a game medal is inserted (or bet) (S100: yes), a new game can be started, and the series of processes described above are executed.

  On the other hand, if it is determined that a winning combination is made (S110: yes), first, it is determined whether or not the winning combination is a re-playing combination (S112 in FIG. 7). If the player has won the re-gamer (S112: yes), after automatically re-inserting the number of game medals that have been inserted in the game that won the re-player (S114), the game of FIG. Returning to the top of the control process, it is confirmed whether or not a game medal has been inserted (or betted), and if it is confirmed that a medal has been inserted, a process for making the game ready to start is performed (S100).

  On the other hand, if the winning game combination is not a re-game combination (S112: no), the “BB combination”, “RB combination”, “tin small combination”, “plum small combination”, “SB combination” Since the player has won a prize, a process (medal payout process) of paying out the number of game medals corresponding to the winning game player is executed (S116). Such processing is performed by determining the number of game medals to be paid out inside the main control board 200 and then outputting a control signal from the main control board 200 to the medal payout device 118.

  If the game medal is paid out in this way, it is next determined whether or not the winning game combination is the “RB combination” (S118). If the RB combination has been won (S118: yes), the regular bonus game (RB game) described above is performed (S120). On the other hand, when it is determined that the winning game combination is not the “RB combination” (S118: no), it is subsequently determined whether it is the “BB combination” (S122). If the BB combination has been won (S122: yes), the aforementioned big bonus game (BB game) is performed (S124).

  Thus, when winning the RB combination or BB combination, the corresponding bonus game (RB game or BB game) is started. When the predetermined bonus game described above is completed, the main control board 200 subsequently sets the RT flag to ON (S126) and performs a process of setting the RT counter a predetermined number of times (S128). Here, the RT flag is a flag indicating whether or not the gaming state is set to a special gaming state called a replay time (RT) game, and when the RT flag is set to ON, the gaming state is Switch to RT game. As will be described in detail later, when the RT game is started, the probability of winning the re-gamer in the internal lottery is changed. The RT game is continued until a predetermined number of times (for example, 20 games) is played or a bonus game (RB game or BB game) is started. Therefore, in order to be able to determine the end timing of the RT game, when the RT game is started, a predetermined number of times is set in the RT counter for counting the number of games. When the RT flag and the RT counter are set in this manner, the process returns to the beginning of the game control process to check whether or not a game medal has been inserted (or bet) (S100), and the above-described series of processes are executed. The process of setting the RT flag to ON is executed by the main control board 200 in the game control process. When the RT flag is set to ON, the probability of winning the re-game player in the internal lottery process changes. Therefore, the main control board 200 of the present embodiment constitutes one aspect of the “replay probability variation state starting means” in the present invention.

  On the other hand, when it is determined that the winning game combination is not the “BB combination” (S122: no), it is subsequently determined whether it is the “SB combination” (S130). As described above, in the gaming machine 1 of this embodiment, a bonus combination called “SB combination” is provided in addition to “RB combination” and “BB combination”. If the SB role has been won (S130: yes), after performing the above-described single bonus game (SB game) (S132), the game control process is returned to the beginning, and a game medal is inserted (or bet). Is performed (S100), and the series of processes described above are executed.

  On the other hand, when it is determined that the winning game combination is not the “SB combination” (S130: no), any of the “re-playing combination”, “RB combination”, “BB combination”, and “SB combination” may be used. Because there was no, it was a prize for “small role”. The payout of game medals for winning a small role has already been made in S116. In this case, the process returns to the top of the game control process of FIG. 6 and the process of confirming the insertion of game medals (S100) is performed. Thereafter, the series of processes described above are repeated.

  As described above, in the gaming machine 1 of this embodiment, when a game medal is inserted and the start lever 36 is operated, the rotation of the spinning cylinders 20a, 20b, 20c is started, and the spinning cylinder stop buttons 38a, 38b, The game progresses while repeating a series of processes such as game medals being paid out and various bonus games are started depending on whether or not a game combination is established when the cirrus is stopped by pressing 38c. . In order to establish a game combination, in order to obtain a combination of symbols for winning a game combination in the internal lottery process (S102) performed following the operation of the start lever 36 and establishing the selected game combination, The rotating cylinders 20a, 20b, and 20c need to stop at appropriate positions. Therefore, in the following, the internal lottery process (S102) and the rotating rotation stop process (S108) for stopping the rotating cylinder at an appropriate position according to the lottery result will be described in detail.

C-1. Internal lottery processing:
FIG. 9 is a flowchart showing the flow of the internal lottery process performed in the gaming machine 1 of the present embodiment. As described above, this process is a process executed by the main control board 200 simultaneously with the operation of the start lever 36 in the game control process shown in FIGS.

  When the internal lottery process is started, first, a random number for lottery is acquired (S200). The random numbers for lottery can be generated by hardware using a dedicated random number generation circuit mounted on the main control board 200, or can be generated by software using a program for generating random numbers. is there. In any case, the random numbers for lottery are periodically updated, and when the start lever 36 is operated to start the internal lottery process, the random number value at that time is acquired. In the gaming machine 1 of the present embodiment, the data length of the random number is set to 2 bytes, and the random value can take a range of 0 to 65535.

  When the random number for lottery is acquired, it is determined whether or not the RT flag is set to ON (S202). As described above, the RT flag is a flag indicating whether or not the current gaming state is an RT game, and the RT flag is set to ON during the RT game. When the RT flag is not set to ON as in the normal gaming state (S202: no), a lottery table for normal gaming is selected (S204). Here, the lottery table is a table in which a correspondence relationship between random numbers for lottery and game players is set, and a dedicated lottery table is set in advance according to the gaming state. In S204, a process of selecting a lottery table set for a normal game from a plurality of lottery tables is performed.

  FIG. 10 illustrates a lottery table for normal games used in the gaming machine 1 of this embodiment. As described above, the random number value can be in the range of 0 to 65535, but the “random tin value” is assigned to the random value values of 0 to 7000. In addition, “Red 7 BB role” is assigned to the random values 7001 to 7100, “Blue 7 BB role” is assigned to the random values 7101 to 7200, and “RB Role” is assigned to the random values 7201 to 7300. However, 7301 to 7500 are assigned the “watermelon small part”. Further, two game combinations of “re-game combination” and “SB combination” are assigned to the random values of 7501 to 20000. In this way, when a plurality of game combinations are assigned to the same range of random numbers, these game combinations may be called “overlapping combinations”.

  It should be noted that no game combination is assigned to the random number values 20001 to 65535, and therefore, if the random number value is within this range, it is lost. By referring to such a lottery table, it is determined which game player has been won or which game player has not been won by examining which range the obtained random number value is in. Can do.

  On the other hand, when the RT flag is ON, that is, when it is determined that the current gaming state is an RT game (S202: yes), a lottery table for RT games is selected (S206). FIG. 11 is an explanatory diagram illustrating a lottery table for RT games used in the gaming machine 1 of this embodiment. As is clear from comparison with the normal game lottery table shown in FIG. 10, in the RT game lottery table, the range of random values assigned to the re-gamer is 7501-13750, which is half of the normal game. The probability that the re-game player will win internally is set lower than that of the normal game.

  As described above, when the lottery table corresponding to the gaming state is selected, the main control board 200 determines whether or not any game combination has been won internally by referring to the selected lottery table (S208). ). As shown in FIG. 10 and FIG. 11, the lottery table is set with a game combination for a random value. By referring to the lottery table, the lottery random value obtained is any of the lottery values. It is possible to determine whether or not the player is a gamer. For example, if the random value acquired in the normal game is “7284”, it is determined that the player has won the RB role because it is within the random number range 7201 to 7300 with reference to the lottery table of FIG. it can.

  If the random number corresponds to any game combination, it is determined that the internal winning is made (S208: yes), and the winning game combination is set in the internal winning flag ( S210). Here, the internal winning flag is a flag used for storing the result of the internal lottery. The internal winning flag is set to a predetermined address of the RAM mounted on the main control board 200. Here, when two different game combinations are assigned to the acquired random number value, that is, the random number value is within the range of 7501 to 20000 in FIG. 10, or is within the range of 7501 to 13750 in FIG. When the random number value is acquired, it means that two different game combinations, that is, the re-game combination and the SB combination are stored as the internal winning combination at the same time. As described above, a state in which two different game combinations are stored simultaneously as an internal winning combination is referred to as a duplicate winning state.

  FIG. 12A is an explanatory diagram showing the data structure of the address for which the internal winning flag is set. As shown in the drawing, in the gaming machine 1 of this embodiment, the lower 7 bits of 1-byte data provided at a predetermined address on the RAM are used as the internal winning flag. The first bit in these 7 bits is a bit for storing the internal winning combination for the red BB role, and the next bit is for storing the internal winning combination for the blue seven BB role. The next bit is a bit for storing the internal winning of the RB combination. Similarly, the following four bits are bits for storing the internal winning combination of the SB combination, the tin combination, the watermelon combination, and the replay combination, respectively. In the process of S210 of FIG. 9, when it is determined that any game combination has been internally won (S208: yes), a process of setting “1” to the bit corresponding to the internal winning game combination is performed. Therefore, as shown in the lottery table of FIG. 10 or FIG. 11, when the SB combination is won at the same time as the re-game combination, a process of setting “1” to two bits at the same time is performed.

  As shown in FIG. 12B, the RT flag is also set to a predetermined address of the RAM mounted on the main control board 200, similarly to the internal winning flag. In S126 of the game control process described above with reference to FIG. 7, in the process of turning on the RT flag, a process of setting “1” to the corresponding bit is performed.

  When the internal winning flag is set as described above, the internal lottery process is terminated, and after returning to the above-described game control process, the processes after S106 in FIG. 6 are started. If no game winning combination has been won internally (S208: no in FIG. 9), the internal lottery process is immediately terminated and the game control process is resumed without setting the internal winning flag. In the gaming machine 1 of this embodiment, when the internal winning flag “RB combination” or “BB combination” is set, the symbol combination corresponding to the winning combination is not stopped on the active line, and the RB combination Alternatively, only when the winning combination of the BB game combination is not established, the internal winning combination is accumulated and carried over after the next game. That is, the internal winning flag “RB combination” or “BB combination” is set after the next game. Therefore, even if the winning combination of the “RB combination” or the “BB combination” game player cannot be established, the “RB game” or “BB game” can be started if the winning combination is established after the next game. it can. On the other hand, when the “SB combination” or other game combination (“re-playing combination” or “small combination”) is won internally, the symbol combination corresponding to the winning combination is not stopped and displayed on the active line. The internal winning combination will be deleted without being carried over after the next game. In other words, if the predetermined symbol combination cannot be stopped and displayed in the internally won game, the benefits of various game actors are not given and the internal winning flag is erased.

  As described above with reference to FIG. 6, in the game control process, after returning from the internal lottery process, the spinner rotation starting process is performed to rotate the spinners 20a, 20b, and 20c (S106 in FIG. 6), and then the internal lottery process. And the rotation rotation stop process (S108) described below to stop the rotation cylinders 20a, 20b, and 20c at appropriate positions according to the operation timing of the rotation cylinder stop buttons 38a, 38b, and 38c. )I do.

C-2. Revolving rotation stop processing:
FIG. 13 is a flowchart showing the flow of the first half of the spinning cylinder rotation stop process performed in the gaming machine 1 of the present embodiment. FIG. 14 is a flowchart showing the flow of the latter half of the spinning cylinder rotation stop process. These processes are processes executed by the main control board 200 in the game control processes shown in FIGS. 6 and 7.

  In the rotation rotation stop processing, first, it is determined whether or not the rotation speed of the rotation cylinders 20a, 20b, 20c has reached a predetermined value (S300). Immediately after the rotation of the rotating cylinders 20a, 20b, 20c is started, if the rotation speed has not yet reached the predetermined value (S300: no), the process waits until the rotation speed reaches the predetermined value. When the rotation speed reaches a predetermined value (S300: yes), the operation of the spinning cylinder stop buttons 38a, 38b, and 38c is validated (S302).

  Next, as shown in FIG. 1, it is determined whether or not the left rotation stop button (left stop button) 38a is operated among the three rotation stop buttons 38a, 38b, and 38c provided side by side. Is determined (S304). If it is determined that the left stop button 38a has been operated (S304: yes), the operation of the left stop button 38a is invalidated (S306), and then the rotation is performed to stop the left rotating cylinder 20a at an appropriate position. A cylinder stop control process is performed (S308).

  FIG. 15 is a flowchart showing the flow of the turning stop control process performed in the gaming machine 1 of the present embodiment. When such processing is started, first, it is determined whether or not the re-gamer is internally won (S400). As described above with reference to FIG. 12A, since the result of the internal lottery process is set in the internal winning flag, it is easy to refer to the internal winning flag as to whether or not the re-game player has been won internally. Can be judged.

  If it is determined that the re-game player has not been internally won (S400: no), a process for stopping the spinning is performed in accordance with the setting of the internal winning flag and the timing at which the spinning stop button is operated (S402). . As described above, when stopping the spinning cylinder, if a certain game player is elected internally, by operating the spinning cylinder stop button at an appropriate timing, the symbols for establishing the winning game player are aligned. On the other hand, for gamers who are not elected internally, the stop position of each torso will prevent the combination of symbols that will establish a gamer from being prepared regardless of the timing at which the stop button is operated. Need to control. Such control is performed using a dedicated table called a stop table. In this stop table, the rotation position (stop operation position) of the rotating cylinder at the moment when the rotating cylinder stop button is operated, and how much the rotating cylinder rotates from when the rotating cylinder stop button is operated to when the rotating cylinder stops. Correspondence with a rotation angle (stop delay angle or delay time) indicating whether or not to perform is set. The stop table is set for each internal winning flag setting, that is, depending on which game combination is won internally. Therefore, when the rotating cylinder stop button is operated, by referring to an appropriate stop table according to the setting of the internal winning flag from among a plurality of stored stop tables, it corresponds to the stop operation position. Get the set stop delay angle. Then, the rotating drum is stopped at a position rotated by the acquired stop delay angle. In S402 of FIG. 15, the rotation is stopped at an appropriate position while referring to the stop table based on the setting of the internal winning flag and the stop operation position (timing at which the rotation stop button is operated). To perform the process. When the rotating cylinder is stopped in this manner, the rotating cylinder stop control process is ended, and the process returns to the rotating cylinder rotation stop process of FIG.

  On the other hand, when it is determined that the re-gamer is internally won (S400: yes), a process of stopping the spinning cylinder is performed so that the symbols of the re-gamer are aligned (S404). This process is also basically performed in the same manner as the process of S402 described above. In other words, when the rotation stop button is operated, the appropriate rotation table is referenced according to the setting of the internal winning flag, and the rotation is stopped according to the stop delay angle or delay time set for the stop operation position. To perform the process. Here, as described above with reference to FIG. 10 and FIG. 11, when the re-game combination is won internally, since the SB combination is also won, the two internals of the re-game combination and the SB combination The winning flag is set at the same time. For this reason, any of the re-game combination and the SB combination can be established. However, in the gaming machine 1 of this embodiment, the re-game combination is established with priority over the SB combination. Therefore, in S404, referring to a stop table that is set so that the symbols of the re-game players can be easily compared, a process for stopping the spinning cylinder is performed. Thereafter, the rotating cylinder stop control process is terminated, and the process returns to the rotating cylinder stop control process of FIG. In addition, since the process for establishing the re-game role in preference to the SB role is executed by the main control board 200, the main control board 200 of this embodiment is the “re-game priority winning means” in the present invention. 1 aspect is comprised.

  As described above, when the left stop button 38a is operated among the three cylinders 20a, 20b, and 20c (S304: yes in FIG. 13), the left cylinder 20a is referred to with reference to the stop table as described above. To stop at the appropriate position. On the other hand, if the left stop button 38a is not operated (S304: no), the process of stopping the left rotating cylinder 20a is skipped, and then the central rotating cylinder stop button (intermediate stop button) 38b is skipped. It is determined whether or not has been operated (S310). When the middle stop button 38b is operated (S310: yes), after invalidating the operation of the middle stop button 38b (S312), the above-described left is used to stop the middle drum 20b at an appropriate position. As in the case of the rotating cylinder 20a, the rotating cylinder stop control process (see FIG. 15) is performed (S314).

  On the other hand, when the middle stop button 38b is not operated (S512: no), the process of stopping the middle cylinder 20b is skipped, and this time the right cylinder stop button (right stop button) 38c is operated. It is determined whether or not (S518). When the right stop button 38c is operated (S316: yes), after invalidating the operation of the right stop button 38c (S318), the rotation stop control is performed to stop the right rotation cylinder 20c at an appropriate position. Processing (see FIG. 15) is performed (S320). On the other hand, when the right stop button 38c is not operated (S316: no), the process of stopping the right cylinder 20c is skipped.

  In this way, it is determined whether or not the button has been operated for all of the three spinning cylinder stop buttons 38a, 38b, and 38c, and if it has been operated, the process of stopping the spinning cylinder (rotating cylinder stop control process) is performed. Then, it is determined whether or not all the cylinders 20a, 20b, 20c have been stopped (S322). If it is determined that the spinning cylinder stop button has not been operated yet and that there is a rotating spinning cylinder (S322: no), the process returns to S304 again to confirm that the spinning cylinder stop button has been operated. After determining in turn from the left stop button, it is determined whether or not all the cylinders have stopped (S322). Such processing is repeated, and if it is determined that all the spinning cylinders are stopped (S322: yes), processing for operating the RT flag is performed as necessary. Here, the RT flag is a flag that is set to change the gaming state to a special gaming state called RT gaming as described above.

  In the process of operating the RT flag, first, it is determined whether or not the current gaming state is in RT gaming (S324). If the RT game is in progress, “1” is set in the RT flag, so it can be easily determined whether or not the RT game is in progress. If it is not during the RT game (S324: no), the operation of the RT flag is unnecessary, so the rotation rotation stop process is terminated as it is, and the process returns to the game control process shown in FIG. 6 and FIG. Then, the processing after S110 is performed.

  On the other hand, when it is determined that the current gaming state is in RT gaming (S324: yes), a process of subtracting “1” from the RT counter is performed (S326). As described above, the RT game continues until a predetermined number of games (for example, 20 games) are played or a bonus game (RB game or BB game) is started. The RT counter is a counter for counting the number of games played during the RT game, and a predetermined number is set at the start of the RT game (see S128 in FIG. 7). Therefore, if all the spinning cylinders are stopped as described above during the RT game, the number of games is digested once, so after subtracting “1” from the RT counter and counting the number of games, It is determined whether or not the RT counter has reached “0”, in other words, whether or not the number of games in the RT game has reached a predetermined number (S328). If the predetermined number of times has been reached (S328: yes), the RT flag is set to OFF to end the RT game (S330). On the other hand, if the RT counter is not “0”, that is, if the number of games during the RT game has not yet reached the predetermined number (S328: no), it is determined whether the BB combination or the RB combination is established. Confirmation is made (S332), and if any bonus combination is established (S332: yes), the RT flag is set to OFF even if the RT counter is not "0" (S330). On the other hand, when the RT counter is not yet “0” (S328: no) and the bonus combination is not established (S332: no), the RT flag is kept ON. The above-described spinning cylinder rotation stop process is terminated and the process returns to the game control process.

  As described above with reference to FIG. 6 and FIG. 7, in the game control process, when returning from the above-described spinning rotation stop process, it is determined whether or not any game combination is established (see FIG. 6). S110), paying out a game medal or bonus game depending on the presence or absence of a prize or the winning game player. If the RB role or BB role is won, after the bonus game (RB game or BB game) is finished, a game called a replay time (RT) game in which the internal winning probability of the re-game role is different from that of the normal game. Transition to the state. In the gaming machine 1 according to the present embodiment, it is possible to give a new game by using a function of changing the winning probability of the re-gamer when switching to the RT game. This point will be described below.

D. Gameability obtained by the gaming machine of the first embodiment:
FIG. 16 is an explanatory diagram schematically showing the configuration of a lottery table used in the gaming machine 1 of the first embodiment. FIG. 16A shows a random number range assigned to each game combination in the base game lottery table shown in FIG. As shown in the figure, most of the random number range is assigned either a tin small role, a BB (red 7) role, a BB (blue 7) role, an RB role, a watermelon small role, or a loser. On the other hand, the re-game combination and the SB combination are assigned to some random number ranges. For this reason, in the above-described internal lottery process (FIG. 9), if the acquired random number value for internal lottery is a random number value within this overlapping range, the re-game combination and the SB combination are The internal winning flag of the game player is set at the same time (S208, S210 in FIG. 9). However, in the spinning cylinder stop control process (FIG. 15), control is performed to stop each spinning cylinder so that the re-game player is established with priority (S400: yes, S404 in FIG. 15). Even if both the SB combination and the SB combination are won, substantially only the re-game combination is established and the SB combination is not established. In FIG. 16 (a), the single bonus (SB) portion is hatched to indicate that even if an internal winning is made, it is not possible to establish a winning. .

  FIG. 16B shows the random number range assigned to each game combination in the RT game lottery table shown in FIG. As is well known, the RT game can change the winning probability of the re-gamer with respect to the normal game, and in the gaming machine 1 of the first embodiment, the normal game is set in the state of the overlapping role. The probability of winning the re-gamer is reduced to half the probability in RT games. As a result, as shown in FIG. 16B, a random number range in which the SB combination is independently won is generated. When the SB combination is won alone, the SB combination can be established by operating the rotation stop button at an appropriate timing (S400 in FIG. 15: no, S402).

  As described above, in the gaming machine 1 of the first embodiment, the re-game combination established with priority and the two game combinations of the SB combination are set to be internally won. Further, in the RT game that can change the winning probability of the re-gamer, the winning probability of the re-gamer is set to be lower than that of the normal game. Both overlapping roles and RT games have been widely used by themselves, but by combining these two in the state set as described above, the following unexpected game characteristics can be exhibited. Is possible. In other words, in the normal gaming state, the SB combination is always won in duplicate with the re-playing combination, so it is in a state hidden behind the re-playing combination and the SB combination is not established. On the other hand, in the RT game, since the winning probability of the re-gamer is reduced, the SB role hidden in the re-gamer can be established. Therefore, the player feels that the player has switched from a gaming state in which the SB role is not established to another gaming state in which the SB role can be established, even though the RT game is merely performed in terms of control. , It will be possible to greatly excite the interest in gaming.

  In addition, the probability that a re-playing role is established by winning a duplicate role in a normal game is not so high (about 1/5), and can be established by reducing the winning probability of a re-playing role during RT game. The probability that the SB combination will be established is not so high. Therefore, even if it sets as mentioned above, a player's gambling will not be excessively increased.

E. Second embodiment:
In the gaming machine 1 according to the first embodiment described above, the rate of decrease in the probability of internally winning the re-gamer during the RT game is fixed. However, it is possible to set a plurality of reduction ratios of the winning probability of the re-gamer and change them. Hereinafter, such a second embodiment will be described.

  FIG. 17 is a flowchart showing the flow of the internal lottery process performed in the gaming machine 1 of the second embodiment. This process is a process executed by the main control board 200 simultaneously with the operation of the start lever 36 in the game control process shown in FIGS. Similarly to the first embodiment described above with reference to FIG. 9, in the internal lottery process of the second embodiment, when the process is started, first, a random number for lottery is acquired (S500), and then the RT flag It is determined whether or not is set to ON (S502). As described above, the RT flag is a flag indicating whether or not the current gaming state is in RT gaming. If the RT flag is not set to ON (S502: no), it is determined that the game state is normal, so the lottery table set for normal game shown in FIG. 10 is selected (S504). ).

  On the other hand, if the RT flag is ON, that is, if it is determined that the RT game is in progress (S502: yes), then, is the RT game started after the end of the BB game? It is determined whether or not (S506). Similar to the first embodiment described above, the RT game of the second embodiment is started after the end of the BB game or the RB game (see S126 and S128 in FIG. 7). If it is determined that the game is not an RT game after the BB game (S506: no), the RT game is started after the RB game, so the lottery table set for the RT game after the RB game is set. Is selected (S508). FIG. 18 is an explanatory diagram illustrating a lottery table for RT games after RB games used in the gaming machine 1 of the second embodiment. As shown in the drawing, in the lottery table for the RT game after the RB game, a random number value is not assigned to the re-gamer, and the probability that the re-gamer is won internally is set to “0”. Yes.

  On the other hand, if the RT game was started after the end of the BB game (S506: yes), then whether or not the symbol that resulted in the winning of the BB role was "Red 7"? Make a decision. Similar to the first embodiment described above with reference to FIG. 6, in the second embodiment, three “red 7” symbols or three “blue 7” symbols are aligned on the active line. A winning combination for the BB role is established. If the winning combination of the BB role is based on “blue 7” instead of “red 7” (S510: no), it is set for the RT game started after the end of the BB game by “blue 7”. The selected lottery table is selected (S512). FIG. 19 is an explanatory diagram illustrating an RT game lottery table after a BB game with “Blue 7” used in the gaming machine 1 of the second embodiment. As shown in the figure, the random number range assigned to the re-gamer is narrower from 7501 to 11250 than the lottery table for normal game shown in FIG. On the other hand, the probability is set to 1/3.

  On the other hand, when the winning combination of the BB role is based on “Red 7” (S510: yes), the lottery table set for the RT game started after the end of the BB game by “Red 7”. Is selected (S514). In the gaming machine 1 of the second embodiment, the lottery table shown in FIG. 11 is used as the RT game lottery table after the BB game by “Red 7”, and the winning probability of the re-gamer is in the normal game. On the other hand, the probability is set to half. Since the plurality of lottery tables having different winning probabilities for the re-gamer described above are stored in the main control board 200, the main control board 200 of the second embodiment is the “re-game probability fluctuation” in the present invention. It constitutes one mode of “ratio storage means”.

  As described above, when a lottery table that matches each condition is selected, the main control board 200 refers to the selected lottery table, and based on the random number for lottery acquired in S500, It is determined whether or not the winning combination has been won internally (S516). If any of the game combinations is won internally (S516: yes), a process of setting an internal winning flag corresponding to the won game combination is performed (S518). On the other hand, if none of the game players have been internally won (S516: no), the internal lottery process is terminated without setting the internal winner flag, and the game control process of FIGS. 6 and 7 is resumed. To do.

  As described above with reference to FIGS. 6 and 7, in the game control process, after returning from the internal lottery process described above, the rotating cylinders 20a, 20b, and 20c are rotated (S106 in FIG. 6), and the rotating cylinder rotation is stopped. When processing is performed and the cylinders 20a, 20b, and 20c are stopped at appropriate positions (S108), a winning determination is made (S110), and game medals are paid out according to the presence or absence of the winning or the type of the winning game player And bonus games. If the RB combination or BB combination is won, the RT flag and RT counter are set to start the replay time (RT) game after the bonus game (RB game or BB game) ends (S126). , S128). At this time, the RT counter is subjected to processing for setting the upper limit number of games played during the RT game. In the gaming machine 1 of the first embodiment described above, a common predetermined number of times after any bonus game (for example, , 20 games) was set on the RT counter. However, the number of games set in the RT counter may be changed in accordance with various conditions (such as the type of bonus combination or the formation pattern of the bonus combination). For example, in the gaming machine 1 of the second embodiment, “10 games” is set in the RT counter after the RB game, “20 games” is set after the BB game where the BB role is established with the symbol “blue 7”, “ “30 games” are set after the BB game where the BB role is established with the symbol “Red 7”. Therefore, it is possible to continue the RT game after the bonus game for a long time in the order of “Red 7”, BB role, “Blue 7”, BB role, and RB role.

  FIG. 20 is an explanatory diagram for comparing the configurations of the four lottery tables used in the gaming machine 1 of the second embodiment. FIG. 20A schematically shows a random number range assigned to each game combination in the normal game lottery table shown in FIG. FIG. 20B shows a random number range of the RT game lottery table after the BB game by “Red 7” shown in FIG. 11, and FIG. 20C shows “Blue 7” shown in FIG. FIG. 20D schematically shows the random number range of the RT game lottery table after the RB game shown in FIG. 18, respectively. As is clear from the comparison of the configurations of these four lottery tables, only the random number range assigned to the re-gamer, that is, the winning probability of the re-gamer is different. In the game, the winning probability of the re-gamer is reduced to half the probability of the normal game. In addition, in the RT game after “Blue 7” BB game, the winning probability of the re-gamer is reduced to 1/3 of the normal game, and in the RT game after the RB game, The winning probability is “0”. Similarly to the first embodiment described above, in the gaming machine 1 of the second embodiment, the re-playing combination that is established with priority and the SB combination are set as overlapping combinations. The SB combination that is hidden behind the game combination and cannot be established can be established during the RT game by reducing the winning probability of the re-game combination. Therefore, the lower the probability of winning a re-game player, that is, the SB role is more likely to be established in the RT game after the bonus game in the order of the RB role, the “Blue 7” BB role, and the “Red 7” BB role. ing.

  As described above, in the gaming machine 1 of the second embodiment, in the RT game started after the end of the bonus game (RB game or BB game), a plurality of ratios for reducing the winning probability of the re-gamer are set. The winning probability of the re-gamer is reduced in accordance with the type of bonus game and the formation pattern of the bonus game. For this reason, the probability that the SB combination is established differs substantially depending on which bonus game the RT game is after, and it is possible to add variations to the game content of the RT game. Then, for a player, it is more advantageous that the SB combination is more likely to be established, that is, the lower the probability of winning the re-gamer, the more advantageous. It is possible to change the player's expectation for the game, and as a result, it is possible to effectively excite the game.

  In the gaming machine 1 of the second embodiment, the upper limit number of games played during the RT game is set to a smaller value for the RT game in which the winning probability of the re-gamer is set lower. . In other words, the RT game set so that the SB combination is likely to be established is set to end in a short period of time, so that the player's gambling feeling is not excessively increased.

F. Third embodiment:
In the gaming machine 1 of the first embodiment and the second embodiment described above, the re-playing role is set as an overlapping role with the SB role, and during the RT game, the re-playing role is won for the normal game. It was set to reduce the probability. However, it is also possible to set a re-gamer to be internally won independently and to change the winning probabilities of the two types of game players separately from the re-gamer in the state of the duplicate role. Hereinafter, the third embodiment will be described.

  Similarly to the first embodiment described above with reference to FIG. 9, in the internal lottery process of the third embodiment, after obtaining random numbers for lottery (see S200 in FIG. 9), the current gaming state is a normal game. It is determined whether there is an RT game or an RT game (S202), and an appropriate lottery table is selected according to the gaming state (S204, S206). FIG. 21 is an explanatory diagram illustrating a lottery table for normal games used in the gaming machine 1 of the third embodiment. The lottery table shown in FIG. 10 is set with a replaying game (replaying game A) in which the random number range overlaps with the SB role compared to the normal game lottery table of the first embodiment shown in FIG. However, it is different from the SB combination in that it does not overlap with the SB combination, that is, the re-playing combination (re-playing combination B) allocated to a part of the random number range is set (hereinafter referred to as “re-playing combination B”). Then, such a game combination assigned independently is called “single combination”). Moreover, FIG. 22 is explanatory drawing which illustrated the lottery table for RT games used with the gaming machine 1 of 3rd Example. As shown in the figure, a random number range is not assigned to the re-gamer A, and the probability that the re-gamer A will win internally is set to “0”. On the other hand, the random number range assigned to the re-gamer B has increased significantly. As a result, the probability of winning the re-gamer B during the RT game is set to be higher than the internal winning of the re-gamer A or the re-gamer B in the normal game. After selecting an appropriate lottery table for normal games or RT games in this way, by referring to the selected lottery table, based on the acquired random number for lottery, the presence / absence of the internal winning and the type of the game player won internally Judgment is made (S208).

  FIG. 23 is an explanatory diagram schematically showing the configuration of two lottery tables used in the gaming machine 1 of the third embodiment. FIG. 23A schematically shows a random number range assigned to each game combination in the lottery table for normal games shown in FIG. Similar to the first embodiment described above, in the gaming machine 1 of the third embodiment, the re-game player A that is a duplicate role with the SB role is set so that a winning is established in preference to the SB role. In effect, the SB combination is not established. In addition, the gaming machine 1 of the third embodiment is provided with a re-playing role B for independent internal winning separately from the re-playing role A that is in a duplicated state. For this reason, in the normal game, when the internal combination is won for the duplicate combination (re-play combination A and SB combination) or the internal combination is won for the re-play combination B, the re-play combination is easily established.

  FIG. 23B schematically shows a random number range assigned to each gaming machine in the lottery table for RT games shown in FIG. As described above, in the RT game, the winning probability of the re-gamer can be changed with respect to the normal game. Therefore, in the RT game of the third embodiment, as shown in FIG. 23 (b), the winning probability of the re-game player A set as a duplicate game in the normal game is reduced to “0”, The winning probability of the re-gamer B set as a single role is greatly increased. As a result, in the normal game, the SB combination that is not established due to the priority of the re-game combination A can be established during the RT game. Furthermore, since the increase in the winning probability of Re-Gamer B exceeds the decrease in the winning probability of Re-Gamer A, as a result, the winning probability of the Re-Gamer becomes higher than the normal game during RT game. Yes.

  In this way, in the gaming machine 1 of the third embodiment, two types of re-games, that is, a re-play game role A that is a duplicate role with the SB role and a re-play game role B that is a single role, are set, and RT During the game, the winning probability of the re-gamer A is set to be decreased, and the winning probability of the re-gamer B is set to be larger than the decrease in the re-gamer A. In gaming machines equipped with RT games, it is common for the winning probability of re-gamers to increase during RT games, which is advantageous to the player in that it can be played without much reduction of game medals. Since the winning probabilities of the game players do not change, only the re-game players tend to be established and the game tends to be monotonous. However, in the RT game of the third embodiment, the winning probability of the re-gamer B is greatly increased, so that the re-gamer is established with a high probability, which is advantageous to the player, and further By reducing the winning probability of the game combination A, the SB combination can be established, and the number of game medals can be increased even during the RT game. That is, not only is it easy to win a re-game player, but an SB player who does not win in a normal game can win, so that it is possible to prevent the RT game from becoming monotonous. It is possible to greatly enhance the interests of the gamers.

  While various embodiments of the present invention have been described above, the present invention is not limited thereto, and is not limited to the wording of each claim unless it departs from the scope described in each claim. Improvements based on the knowledge that a person skilled in the art normally has can also be added as appropriate to the extent that those skilled in the art can easily replace them.

  For example, in the above-described embodiment, it has been described that a duplicate combination of a replay combination and an SB combination is set in a normal game, and the winning probability of a replay combination constituting a duplicate combination is reduced during an RT game. . However, on the contrary, in the normal game, at least a part of the SB role (or another game role may be used) is set in a single role state, and during RT game, a duplicate role with the SB role is configured. It is also possible to increase the winning probability of the re-gamer. In this way, the SB role can be established in the normal game, whereas in the RT game, the SB role is won as a duplicate role with the replay role and the replay role is preferentially established. It will not be established. In other words, in an RT game, an increase in the winning probability of a re-game that constitutes an overlapping role with an SB role will result in an impression that the gaming state is switched from a gaming state where the SB role is established to another gaming state that is not established. Can be given to a person.

  In the second embodiment described above, the rate of change of the winning probability of the re-gamer changes for each symbol for which the bonus is established. However, each time the RT game is started, It is good also as what determines the variation rate of winning probability. For example, among the RT game lottery tables stored in plural, which one to use is determined by lottery at the start of the RT game. Then, the RT game using the determined RT game lottery table is started. By doing so, the gameability of the RT game can be changed every time the RT game is started, so that the interest of the player can be enhanced.

  In the above-described embodiment, the case where the replaying combination and the SB combination are set as the overlapping combination has been described. However, the gaming combination constituting the overlapping combination with the replaying combination is not limited to the SB combination. . For example, the present invention can be preferably applied to a case where a duplicate combination of a challenge time (CT) combination and a replay combination that ends in one game is set. That is, the SB combination used in the first embodiment, the second embodiment, and the third embodiment described above can be replaced with the CT combination. In this case, the same effect as the SB combination can be obtained. In addition, the game actors constituting the duplicate game role with the re-game player are not limited to the SB role and CT role, and any game character can be designated as a re-game character as long as it does not carry the internal winning flag after the next game. It may be set as a duplicate combination.
