Description

  The present invention relates to a revolving game machine that generates a special game state advantageous to a player when a plurality of symbols displayed in a display area are stopped and displayed in a specific symbol arrangement.

  Conventionally, in a swivel-type game machine, also called a slot machine, if a specific symbol such as “7” is stopped and displayed in a line in a row in a display area, a bonus winning combination is established. A special gaming state is generated (a so-called big bonus (BB) game is started).

  A BB game is a regular bonus that is played when a specified number of general games (also referred to as BB general games) and replay symbols (or JACK symbols, hereinafter referred to as replay symbols) are arranged in a row in this general game. (Also referred to as RB) game.

This RB game is generally performed up to three times (or twice) during the BB game, and the BB game ends when the maximum number of RB games is reached.
During the RB game, the special content that the number of medals to be used is forcibly reduced to the minimum number (for example, one), and that the maximum number (for example, 15 pieces) is paid out when three replay symbols are arranged in a line. It has become.

  During the RB game, the probability that three replay symbols are arranged in a row increases to about 90%, so that the player can easily obtain a large number of medals. When the RB game ends during the BB game and the number of times does not reach the maximum number, the game returns to the BB general game again. In the BB general game, the small role winning (a state in which three symbols such as watermelons are arranged in a row, etc., only a predetermined number of medals are paid out and does not shift to a BB game or an RB game) is higher than usual. Since it occurs with a probability, the player can obtain the next best payout by winning the small role even without shifting to the RB game.

Note that if the BB general game is played the prescribed number of times during the BB game, the BB game is ended even if the number of RB games played during the BB game is less than the maximum number.
Also, in the slot machines, after the BB game ends, a specific game (for example, CT (Challenge Time), AT (Assist Time), etc.) that is advantageous to the player, which is different from the BB game or RB game, occurs. Some models are configured to do this (see, for example, Patent Document 1).

As described above, by making it possible to execute a specific game that is advantageous to a player different from the BB game or the RB game, the gaming interest of the slot machine is improved.
JP 2002-172206 A

  By the way, a player who plays in the slot machine as described above plays a game with an emphasis on the occurrence of a BB game or an RB game with a low occurrence frequency, and further, accompanying the occurrence of the BB game or RB game, It is common to play a game with the expectation that the above-mentioned specific game will occur.

  However, even if the conventional slot machine is equipped with the above-mentioned BB game, RB game, or specific game, the game playability has become uniform for all types of machines, and the game entertainment is also decreasing.

  Further, in the conventional slot machine, emphasis is placed on the occurrence of a BB game or a specific game, and the player plays a game with a sense of expectation for the occurrence of the BB game or the specific game. For this reason, even if the RB game is generated, the player cannot obtain much satisfaction, and the RB game tends to be neglected.

The present invention has been made in view of such problems, and an object of the present invention is to provide a swivel-type gaming machine having a novel game performance that has not been conventionally available.
Another object of the present invention is to provide a revolving type gaming machine that realizes the gameability in which the gameability of the RB game plays a central role in the game and increases the existence value of the RB game.

  Still another object of the present invention is to provide a revolving type gaming machine capable of giving a player the impression that RB games having the same contents have different contents.

  In order to achieve the above object, according to the present invention, the invention according to claim 1 includes a plurality of spinning cylinders having a plurality of symbols formed on the outer peripheral surface, and the variation of the symbols by rotating and stopping the plurality of spinning cylinders. A variable display means capable of stopping display, a prize mode determining means for determining a prize mode by random number lottery, and a stop for rotating the player based on a prize mode determined by the prize mode determining unit and a player's stop operation. In a revolving game machine comprising a control means and a privilege granting means for granting a privilege to a player when a winning is achieved by an arrangement of symbols stopped and displayed on a variable display means, during a normal game, a prize mode When the determination means determines the award mode as the first privilege, the first privilege cannot be awarded for the first privilege. In the first privilege impossible state, the award mode determination unit determines the award mode as the second privilege. 1st privilege impossible state Characterized in that the number of games until the end is set.

As a result, according to the present invention, it is possible to realize a spinning-type gaming machine having a gaming property that is not found in a conventional spinning-type gaming machine.
Specifically, as in the invention described in claim 2, the first privilege is a high payout game for giving a high payout to a player, and the second privilege is a prize mode determined by the award mode determining means. One example is a winning assist game that assists in establishing a winning prize.

  As a result, when a high payout game (so-called regular bonus, hereinafter also referred to as RB) is determined as the award mode (when the regular bonus is internally won) by the award mode determining means during the normal game, the regular bonus is won. In this state, when the winning assist game (so-called AT (Assist Time)) is determined as the winning mode by the winning mode determining means (when the AT is internally won), the regular bonus cannot be won. The number of games until the state is finished is determined.

  Then, when the regular bonus non-winning state ends, the regular bonus can be won, and when a game with the regular bonus winning (hereinafter also referred to as an RB game) is over, AT will continue to occur. It becomes.

  In other words, the internal winning of RB and the establishment of a winning will lead to the internal winning and generation of AT, thereby realizing gameability with an emphasis on the RB game and increasing the existence value of the RB game.

  In the invention described in claim 3, in the swivel type gaming machine according to claim 2, when the award mode determining means determines the award mode as the second privilege in the first privilege disabled state, The number of games is determined, and the determined number of games of the second privilege is divided and displayed for each game in the high payout game of the first privilege.

  As a result, according to the rotary type gaming machine according to the present invention, it is possible to give the player the impression that the number of AT games is being drawn during the RB game, and increase the existence value of the RB game. be able to.

  In the invention described in claim 4, in the swivel-type gaming machine according to claim 2 or 3, the first privilege winning symbol during the normal game and the first privilege winning symbol during the second privilege game are different from each other. It is a pattern.

  Thereby, according to the swivel type gaming machine according to the present invention, since the first privilege (RB) winning symbol is changed according to the gaming state, the first privilege (RB) having the same content is a different privilege. An impression can be given to the player.

As described above, the spinning-reel game machine according to the present invention can provide a novel game performance that has not existed before.
In addition, in the spinning-type gaming machine according to the present invention, the gaming nature of the RB game can realize the gaming nature that plays a central role in the game, so that the existence value of the RB game in the spinning-type gaming machine is increased. Can do.

  Furthermore, in the rotary type gaming machine according to the present invention, it is possible to give the player the impression that the RB game having the same content is different.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. In the present embodiment, the present invention is applied to a slot machine 1 which is a specific example of a rotating type gaming machine.
First, the structure of the slot machine 1 will be described with reference to FIGS. FIG. 1 is a front view of the slot machine 1. As shown in FIG. 1, the front portion of the slot machine 1 has a slot 3 for inserting medals, a single BET button 5 for using one of the inserted medals, and three of the inserted medals. 3 BET buttons 7 that use, a start lever 9 for starting rotation of three reels (revolving cylinders), a reel display unit 11 in which three reels stored inside the slot machine 1 are visible from the outside, and rotation The stop buttons 13L, 13C, and 13R for stopping the reels are configured as main parts.

  The three reels 75L to 75R and the reel display unit 11 correspond to variable display means of the present invention. The stop buttons 13L, 13C, and 13R are used to stop the left reel, the middle reel, and the right reel in the reel display unit 11, respectively. As a result of the stop, when a prize is won, a medal of the number corresponding to the winning result is awarded to the player from the medal payout opening 15. Note that the number of unused medals inserted into the insertion slot 3 is displayed on the game medal storage number display 19 as the number of credits. The maximum number of credits is 50, and the amount exceeding 50 is paid out to the tray 17.

  When the 1-sheet BET button 5 is pressed once, the medal insertion number display lamp 21a is turned on to indicate that only one horizontal center line is valid, and when pressed once more, the medal insertion number display lamps 21b and 21b are also displayed. Illuminates to indicate that the upper, middle, and lower 3 lines are valid, and when pressed once more, the medal insertion number display lamps 21c and 21c also illuminate and add 2 diagonal lines to the upper, middle, and lower 3 lines. It shows that a total of 5 lines are valid.

  When the three-BET button 7 is pressed, all the medal insertion number display lamps 21a to 21c are turned on to indicate that the five lines are valid. The number-of-games display 23 displays an operable number of times during an RB game described later, the number of AT games described later, and the like. A game medal payout number display (not shown) displays the number of game medals being paid out.

  The replay lamp (not shown) is turned on when the reels stop and the replay symbols are aligned on the reel display unit 11 (wins the replay role). Is turned on when it is possible to input The return button 31 is used when the inserted game medals are jammed, the checkout button 33 is used to pay out medals stored as credits, the door key 35 is a door key, and a stop state. The store clerk operates to cancel.

  The notification lamps 30a and 30b are lit when the RB, which will be described later, can be awarded. One of the notification lamps 30a and 30b is turned on according to a gaming state (mode) described later.

  The slot machine 1 can borrow a medal using a prepaid card. For this, first, a prepaid card is inserted into the insertion slot 43 into the inter-table sand 41 installed on the left side of the slot machine 1. Then, the balance of the prepaid card inserted into the balance display device 45 provided on the right side of the three-BET button 7 is displayed. The balance display device 45 is a three-digit seven-segment display device, and “030” is displayed on the balance display device 45 when the price of 3000 yen remains on the prepaid card. When the player presses the lending button 47 located further to the right of the balance display device 45 once, 500 yen medals are paid out from the medal payout exit 15 and the balance display is reduced by 5 (“030” in the above example). Becomes “025”). When the number of credits is less than 50, the credit may be increased to 50 when the lending button 47 is pressed, and a portion exceeding 50 may be paid out to the tray 17. When the player presses the card return button 49 further to the right of the lending button 47, the prepaid card comes out from the insertion port 43. The prepaid card is purchased with a vending machine installed inside the store where the slot machine 1 is installed.

  When a game is played using the slot machine 1, various sound effects flow from the speaker 51, and various lamps included in the slot machine 1 including the lantern lamp 53 are repeatedly lit and flashed to produce an effect that excites the game. Done.

  FIG. 2 shows a control system of the slot machine 1. The control system of the slot machine 1 includes a CPU 63 that executes various computer programs, a RAM 65 that functions as a work memory, a ROM 67 that stores control programs and data for comparison determination, and a reference clock that defines the operation timing of the CPU 63. An operation clock generation circuit 69 for generating a signal and a random number generation circuit 71 for generating a random number used for processing related to a game are mainly configured.

  Further, the CPU 63 sends signals to the CPU 63 indicating that the stop buttons 13L to 13R, the start lever 9, the 1-sheet BET button 5, the 3-sheet BET button 7, the return button 31, the card return button 49, and the lending button 47 are operated. The switch interface for transmission (denoted as switch I / F in this figure), the motor drive circuit 77 for controlling the three motors M for rotating the reels 75L, 75C, 75R, and the rotational positions of the reels 75L, 75C, 75R The slot machine 1 includes a reel position detection circuit 81 that transmits signals from the optical sensors 79L, 79C, and 79R to be detected to the CPU 63, a speaker drive circuit 83 that generates sound effects from the speakers 51, and a ceiling lamp 53. The lamp drive circuit 85 for driving the lamp and the balance display device 45 have a predetermined number. Like a hopper drive circuit 91 for paying out a predetermined number of medals are connected display driver 87 to display, and the hopper 89 to pay out medals from the medal payout opening 15 appropriately driven to the. The lending button 47 and the switch interface 73 are connected via a relay 93. The relay 93 is configured to be turned ON / OFF by a signal sent from the CPU 63 through the relay drive circuit 95. Yes.

  FIG. 3 shows symbols drawn on the reels 75L to 75R. Each of the reels 75L to 75R has seven types of symbols such as “7”, “Cherry”, “Bat” and “Tin” shown in the figure on the outer peripheral surface. And a special gaming state is generated.

  The outline of the main process executed by the CPU 63 during the game is shown in the flowchart of FIG. This process is repeatedly executed in a state where there is a credit. When this process is activated, it is first determined in S400 whether or not a predetermined number of medals have been inserted (in particular, this indicates that one of the BET buttons 5 and 7 has been pressed). If no medal is inserted (S400: NO), the process returns to S400 and waits for a medal to be inserted.

  When a medal is inserted (S400: YES), the process proceeds to S410, and it is determined whether or not the start lever 9 is operated (indicated as “lever on” in FIG. 4). If the start lever 9 is not operated (S410: NO), the process returns to S410 and waits for the start lever 9 to be operated.

  When the start lever 9 is operated (S410: YES), the process proceeds to S420, and it is determined whether or not the game start waiting time has elapsed. If the game start waiting time has elapsed (S420: YES), the process proceeds to S430. If the game start waiting time has not elapsed (S420: NO), the process returns to S420 and waits for the game start waiting time to elapse.

  In S430, a mode confirmation process is performed. That is, it is confirmed whether the slot machine 1 is currently in the gaming state of modes 0 to 5. Mode 1 is a normal gaming state, and the game starts from this state. Mode 2 is a normal gaming state and an AT state. This state is entered after the end of the RB game (which will be described later in Mode 0).

  Note that the AT in mode 2 of the present embodiment notifies the pressing order of the stop buttons 13L to 13R that can reliably establish a winning combination such as a small combination or bonus combination, and in this embodiment, the reel 75L to It is assumed that the push order is notified by a change in illumination of 75R and a change in lighting state of the stop buttons 13L to 13R. And AT in this mode 2 has shown the one aspect | mode of the 2nd privilege and winning assistance game of this invention.

  Mode 3 is a state in which RB is internally won in mode 2. Since the mode 2 is AT, it is possible to win the RB by completely drawing it in by simply operating the stop buttons 13L to 13R in accordance with the notified pressing order. Although it is mixed, mode 5 is a mode that shifts when RB is internally won in mode 1, but the RB game does not occur immediately.

  This is because when the RB is internally won in mode 1, the winning flag is stored in the RAM 65 and the high probability replaying state (RT state) is entered. In this RT state (mode 5), a reel stop control table in the RT state is used in a reel stop process described later. As the reel stop control table used during the RT state, an RB winning disable table set so that the stop position of the reels 75L to 75R is set to a position where no RB winning is established is used. For this reason, RB winning is impossible unless the RT state ends.

  In the RT state, the winning probability of the replay role is higher than in the normal gaming state, but if the replay role is won according to the winning probability, the RB is internally won (the current gaming state is the mode). 5) is easily known to the player, and there is a risk that the gaming interest will be reduced.

  Therefore, the reel stop control table used in the RT state is set so as to control the reel stop position so that the probability of winning the replay combination is substantially the same as in the normal game state.

  When RB is won internally in mode 1 (shifting to mode 5), the ceiling counter is set. When this ceiling counter is counted down with the progress of the game and becomes 0, or when winning the AT role, the AT counter which is the number of AT games and the RT counter until the RT end are set. The AT counter is set in units of 16 games from 16 to 512 games.

  When the RT counter reaches 0, when the RT state, that is, when mode 5 ends, the mode 4 is entered. Mode 4 thus generated is a state in which the RB game is internally won, and the RB game can be won. When winning RB in this mode 4 or mode 3, it becomes mode 0, which is an RB game state. And RB (regular bonus) in this mode 0 has shown the 1st privilege of this invention, and the one aspect | mode of a high payout game.

  Returning to FIG. Proceeding to S440, reel rotation processing is performed. The outline of the reel rotation processing is to issue a command to the motor drive circuit 77 and drive the motor M to rotate the reels 75L to 75R. Details of this will be omitted.

  When the reel rotation process is thus completed, it is determined in S450 whether the mode is 1 or 2. If the mode is 1 or 2 (S450: YES), the process proceeds to S460, lottery processing corresponding to modes 1 and 2 is performed, and a winning flag is set in S470.

  Here, “setting the winning flag” means storing a lottery result based on the operation of the start lever 9 in the RAM 65. Note that the winning flag related to the RB is stored in a plurality of games until the RB winning is established, and the winning flag relating to the other role is determined whether the winning is established or not established at the end of the game in which the flag is set. Regardless, it is erased.

  Returning to FIG. 4, when the mode is not 1 or 2 in S450 (S450: NO), the process proceeds to S480, and it is determined whether the mode is any of 3, 4, and 5. If the mode is any of 3, 4, and 5 (S480: YES), the process proceeds to S490, lottery processing corresponding to modes 3 to 5 is performed, and a winning flag is set in S470. If the mode is neither 3, 4, or 5 (S480: NO), the process proceeds to S500, a lottery process corresponding to mode 0 is performed, and a winning flag is set in S470.

  These processes of S460, S490, and S500 constitute one aspect of the award mode determining means of the present invention. In the present embodiment, the RB winning probability is set to a high probability of about 1/30, and the AT winning probability is set to about 1/400 to 1/500.

  In addition, when the RB is internally won (RB winning flag is set), that is, in the mode 5, the RB winning probability is set to 0%, or the RB is not drawn, so that the RB is not selected. Duplicate winning is not done.

  Processing after the winning flag is set in this way is shown in FIG. In S510, it is determined whether or not the winning flag has an AT role. When there is no AT combination in the winning flag (S510: YES), the process proceeds to S520, and it is determined whether or not there is RB in the winning flag. As for the RB winning flag, the presence / absence of a winning flag is determined including a flag that has been set in the past game and has not yet been deleted.

  If there is no RB in the winning flag (S520: NO), the process proceeds to S530, and an RB winning disable table is set. If there is RB in the winning flag (S520: YES), the process proceeds to S540, and it is determined whether or not the current mode is 1. If the current mode is 1 (S540: YES), the process proceeds to S550, the ceiling counter is set, and the RB prize impossibility table is set in subsequent S560.

  If the current mode is not 1 (S540: NO), the process proceeds to S570, where it is determined whether the current mode is 5. If the current mode is 5 (S570: YES), the process proceeds to S560, and an RB winning disable table is set. If the current mode is not 5 (S570: NO), the process proceeds to S580, and the RB prize winning table is set.

  If YES in S510, that is, if it is determined that the winning flag has an AT role, the process proceeds to S600, the AT counter is set, and it is determined in S610 whether the current mode is 1 or 5. If the current mode is 1 or 5 (S610: YES), the process proceeds to S620, and it is determined whether the RT counter is set. If the RT counter is not set, the process proceeds to S630, the RT counter is set, and the RB winning disable table is set in S640.

  If the current mode is not 1 or 5 (S610: NO), the process proceeds to S650, and it is determined whether the current mode is 3 or 4. When the mode is 3 or 4 (S650: YES), the process proceeds to S840, and an RB winning disable table is set. When the mode is not 3 or 4 (S650: NO), the process proceeds to S660, and the RB winning possible table is set.

  Here, the RB winning disable table and the RB winning enable table are reel stop control tables used for determining the stop positions of the reels 75L to 75R in the reel stop process described later, so that the RB winning is not established. When the reels 75L to 75R are stopped, the RB winning table is used, and when the reels 75L to 75R are stopped so that the RB winning is established, the RB winning table is used. A plurality of reel stop control tables for performing stop control of the reels 75L to 75R are provided according to the winning flag (lottery result) set in S470.

  Incidentally, in the above-described S530, S560, S580, S640, and S680, only RB winning was enabled or disabled, but the reel control table set here enables or disables RB winning. In addition to being a table, it is also a table that enables or disables winning of a role other than RB based on the winning flag set in S470.

  FIG. 6 shows a flow of processing performed subsequent to the processing shown in FIG. In S700, an effect process is performed, and it is determined in S710 whether or not the stop buttons 13L to 13R are pressed. When the stop buttons 13L to 13R are pressed (S710: YES), the process proceeds to S720 to perform a reel stop process. When the stop buttons 13L to 13R are not pressed (S710: NO), the process proceeds to S730 and it is determined whether or not the automatic stop time has elapsed. If the automatic stop time has not elapsed (S730: NO), the process returns to S710 and waits for the stop buttons 13L to 13R to be pressed. If the automatic stop time has elapsed (S730: YES), the reel stop process of S720 is performed.

  The outline of the reel stop process is based on the operation of the stop buttons 13L to 13R, the winning flag that is set (or not) and the reel stop control table, and the reels 75L to 75R are awarded with RB roles, small roles, etc. The stop positions of the reels 75L to 75R are determined so as to be stopped in an established manner or simply in a disengaged manner.

  It should be noted that when the stop buttons 13L to 13R are operated at the timing of stopping in a manner in which a winning is achieved despite not being won, or conversely, the operation is stopped in a manner in which no winning is achieved despite being won. When the stop buttons 13L to 13R are operated at the timing, the reels 75L to 75L are within the allowed range (for example, four symbols (hereinafter also referred to as four frames) drawn on the reel. Within 190 ms). 75R pull-in control or kick-off control is performed to detect the rotational positions of the reels 75L to 75R based on the detection results of the optical sensors 79L to 79R, and the reels 75L to 75R stop in a corresponding manner (symbol arrangement). Control.

  Here, the pull-in control is a reel stop control that makes it easy to stop and display the symbol corresponding to the prize mode on the reel display unit 11, and the kick-off control is the symbol corresponding to the prize mode on the reel display unit 11. This is a reel stop control that prevents the stop display from being performed.

  When the reel stop process is thus completed, it is determined in S740 whether all the reels 75L to 75R have been stopped. If there are reels 75L to 75R that have not been stopped (S740: NO), the process returns to S710 to wait for all the stop buttons 13L to 13R to be pressed and for all the reels 75L to 75R to stop. When all the reels 75L to 75R are stopped (S740: YES), the process proceeds to S750, and it is determined whether or not there is a winning combination.

  If there is a winning combination (S750: YES), it is determined in S760 whether or not it is a replay combination. When winning the replay role (S760: YES), the process returns to S410 (see FIG. 4). Since S410 is after the BET of S400, a lottery can be received without inserting medals or reducing credits. If the winning combination is not a replay combination (S760: NO), the process proceeds to S770, and medals are paid out according to the winning combination, and the process proceeds to S800 shown in FIG. The medals are paid out by transmitting a command to drive the hopper 89 to the hopper drive circuit 91. If it is determined in S750 that there is no winning combination, the process goes straight to S800. In the present embodiment, the processing of S750 to S760 constitutes one aspect of the privilege providing means of the present invention.

  In S800, it is determined whether or not the current mode is 2. If the current mode is 2 (S800: YES), the AT counter is decremented by 1 in S810 and this process is terminated. If the current mode is not 2 (S800: NO), the RT counter is decremented by 1 in S820, and it is determined in S830 whether the current mode is 5 and lost. If the current mode is not 5 or not lost, this process is terminated. If the current mode is 5 and it is lost, the process proceeds to S840 and the ceiling counter is decremented by 1.

  In subsequent S850, it is determined whether or not the ceiling counter is 0. If it is not 0, this process is terminated. If it is 0, the process proceeds to S860 and the AT counter is added. In subsequent S870, it is determined whether or not the RT counter is set. To do. If the RT counter is set (S870: YES), this process ends. If the RT counter is not set (S870: NO), the process proceeds to S880, the RT counter is set, and this process is terminated.

  According to the slot machine as described above, in mode 1, when RB is won internally, it becomes mode 5 (RT state) in which it is impossible to win RB. In this mode 5, when ATT is won internally, RB is won. The number of games up to mode 4 (until the end of mode 5) is set.

  When the mode 5 ends and the mode 4 is shifted to, the RB winning becomes possible. When the RB winning is established, the mode RB is shifted to and the RB game is started. When this mode 0 (RB game) ends, the mode is shifted to mode 2, and AT is generated based on the number of AT games (AT counter) determined at the time of AT internal winning in mode 5.

  In this mode 2, when RB is won internally, the mode is shifted to mode 3, and an RB can be won immediately without generating an RT state. In this mode 3, since the AT also informs the pressing order of the stop buttons 13L to 13R, the player can easily establish the RB winning by simply operating the stop buttons 13L to 13R according to the notified pressing order. Can do.

  Here, even in mode 4, RB winning is possible, but since the pressing order of the stop buttons 13L to 13R is not notified, the player operates the stop buttons 13L to 13R aiming at the RB winning symbol of the reels 75L to 75R. It is necessary to do (so-called “promotion”). On the other hand, since the order of pressing the stop buttons 13L to 13R is notified in the mode 3, the player can easily win a prize without aiming at the RB winning symbols on the reels 75L to 75R.

  In this embodiment, the RB winning probability is set to a high probability of about 1/30. However, when the RB is internally won in mode 0, the mode shifts to mode 5 and RB winning is impossible. Therefore, the RB winning probability depends on the AT winning probability (about 1/400 to 1/500).

  On the other hand, when the RB is internally won in mode 2, the RB can be won immediately without shifting to mode 5, and the RB winning probability does not depend on the AT winning probability, and the RB winning probability (approximately 1 / 30). Therefore, the larger the number of AT games determined in the AT internal winning in mode 5, the longer the period of mode 2, and the longer the period of mode 2, the greater the number of winning RBs. Therefore, the interest of the player is further improved.

  As described above, the slot machine 1 according to the present embodiment performs a game with an emphasis on RB by relating RB internal winning and AT internal winning, and RB winning and AT occurrence. It has new gameplay that is not available in conventional slot machines. Thereby, it is possible to provide a slot machine with a novel gameability that has not existed before.

(Other embodiments)
The present invention is not limited to the above-described embodiments, and is not limited to the wording of each claim unless it deviates from the scope described in each claim. In addition, improvements based on knowledge normally possessed by those skilled in the art can be added as appropriate.

  For example, when the number of AT games is determined in mode 5, the number of AT games may be divided and displayed for each game when mode 0 is entered. In this way, during the RB game (mode 0), it is possible to give the player the impression that the number of AT games is being drawn, and to allow the player to recognize the importance of the RB game.

  Note that the AT game number addition display uses a game number display 23 (see FIG. 1) provided on the front surface of the slot machine 1 or a display (not shown) constituted by a liquid crystal display or a dot matrix display. An apparatus can be provided in the front part of the slot machine 1 and can be performed using the display device. Incidentally, it is preferable to perform addition display using a display device such as a liquid crystal display or a dot matrix display because the effect on the player is further improved.

  Also, the winning symbol of the RB game in mode 5 (during RT) and the winning symbol of the RB game in mode 3 (during AT) may be different from each other. In this way, the winning symbol of the RB game is changed according to the gaming state, so that it is possible to give the player the impression that the RB game having the same content is a different privilege.

  Further, the notification lamp 30a (see FIG. 1) on the front surface of the slot machine 1 is turned on when the mode 5 is shifted, and the notification lamp 30b (see FIG. 1) is turned on when the mode 3 is shifted. If the lighting modes of the notification lamps 30a and 30b for notifying that the RB can be won are different, it is possible to give a stronger impression as if the RB game with the same content is a privilege with different content.

  In the slot machine 1, it is possible to borrow a medal using a prepaid card. However, it is also possible to play a game by borrowing a medal using a known medal lending machine that does not use a prepaid card. In the slot machine 1, a game is played using medals, but a game ball used for a pachinko gaming machine may be used to play a game.
