Description

  The present invention relates to a gaming machine, a program, and an information storage medium.

  2. Description of the Related Art Conventionally, a gaming machine (rotational gaming machine, slot machine) having a plurality of reels having symbols arranged on an outer peripheral surface is known. This type of gaming machine gives a certain game value to game media such as medals and pachinko balls, and performs a game for acquiring such game media. In addition, this type of gaming machine performs an internal lottery that determines whether or not a winning combination is made based on the player's operation, and displays the game result using a combination of symbols arranged on the reel based on the result of the internal lottery. In addition, it has a function of paying out medals when a winning combination is won.

In addition, the probability of winning a small role (a role that pays out medals, etc. when winning a prize) or bonus (a role that triggers a transition to a bonus state where a large amount of medals can be acquired in a short period of time) is maintained at a predetermined change opportunity. There is a gaming machine in which the player is allowed to perform a replay time game by controlling the winning probability of replay (a role that does not require the insertion of medals etc. in the next game due to winning). (See Patent Document 1). In this replay time game, generally, control for changing the winning probability of replay with high probability is performed, and the game can be digested under conditions that are advantageous to the player by winning the replay with high frequency. For this reason, as a specification for giving ups and downs to the player's medal acquisition situation, control is adopted that varies the winning probability of replay in many gaming machines.
JP 2006-334120 A

  On the other hand, in recent gaming machines, a replay time game in which the winning probability of replay is changed to a low probability is performed, the number of continuations of the replay time game is counted, and a predetermined number of replay time games are digested. There is also a model that realizes the so-called ceiling function of changing the winning probability of replay with a high probability as an opportunity.

  However, in the model having the above-described ceiling function, when a bonus is won before the predetermined number of replay time games are consumed, the information on the number of continuations of the replay time game is cleared when the bonus is won. Therefore, if the winning probability of replay fluctuates again with a low probability after the bonus state ends, the replay winning probability does not fluctuate with a high probability unless the predetermined number of replay time games are digested again. It was. For this reason, when the number of continuations of the replay time game is just before the predetermined number of times, the player's labor accumulated so far will be wasted, and the player's willingness to continue the game There is a risk of loss.

  The present invention has been made in view of the above circumstances, and its purpose is to maintain a player's willingness to continue playing for a long time when a so-called ceiling function is realized as a technique for controlling the winning probability of replay. It is an object of the present invention to provide a gaming machine, a program, and an information storage medium that can be used.

  (1) In the present invention, a plurality of reels in which a plurality of types of symbols are arranged on the outer peripheral surface, a small role in which a game medium is paid out in accordance with a prize, and a next game without requiring a game medium in accordance with a prize A lottery means for performing an internal lottery that determines whether or not a plurality of types of winning combinations are to be performed, a control for rotating the plurality of reels, and a control for stopping the plurality of reels according to the result of the internal lottery. Reel control means for performing, game state transition control means for performing control to shift the gaming state between a normal state and a plurality of bonus states in which the winning rate of the small role is higher than the normal state, and the internal lottery As a control for changing the winning probability of replay at a predetermined fluctuation opportunity, the count value C1 is updated by a certain value for each game in a state where the winning probability of replay is set to the probability P1. Replay probability control means for controlling the winning probability of the replay to a probability P2 higher than the probability P1 based on the count value C1 reaching the threshold value Cth1, and in a stopped state of the plurality of reels A gaming machine in which a winning combination is awarded based on the display of a symbol combination indicating a winning combination of a winning combination, wherein the lottery means in addition to the small combination and the replay in the internal lottery in the normal state The determination of whether or not a plurality of types of bonuses that trigger the transition to each bonus state is made, at least one of the plurality of types of bonuses is set as a special bonus, and the replay probability control means includes When a bonus other than the special bonus is won or won in a game in which the winning probability of replay is set to probability P1 In this case, even if the count value C1 does not reach the threshold value Cth1, the updating of the count value C1 is stopped to change the winning probability of the replay, and the winning probability of the replay becomes the probability P1. When the special bonus is won in the set game, the count value C1 does not reach the threshold value Cth1 until at least the special bonus state in which the special bonus is transferred is completed. The count value C1 is updated on the condition that the count value C1 reaches the threshold value Cth1 until a bonus other than the special bonus is won or won even in the game after the special bonus state ends. The present invention relates to a gaming machine that continues to update the count value C1 on the condition that it is not.

  In “Bonus”, “Pocket winning rate is higher than the normal state” means that the control of increasing the winning probability of the small part in the internal lottery is higher than in the normal state, and the small part that is the target of the internal lottery As a result, control to increase the winning probability of a small role by increasing the number of types compared to the normal state, or control to stop multiple reels as if the small role has been won regardless of the result of the internal lottery Etc. are included.

  In the present invention, a so-called ceiling function is implemented in which the replay probability control means performs control to change the winning probability of replay from a low probability to a high probability in accordance with the count value C1 that updates the value for each game. In the present invention, the count value is updated every time a game in which the winning probability of replay is set to a low probability is performed, but when a bonus other than a special bonus among a plurality of types of bonuses is won or won. Control is performed to stop updating the count value and continue updating the count value when a special bonus is won. For this reason, even if a special bonus is won in a game where the winning probability of replay is set to a low probability, the count value update will not be canceled when the special bonus is won. In a game set with a low probability, a special bonus can be won a plurality of times until a predetermined number of games are played. Therefore, according to the present invention, it is possible to improve the medal acquisition situation in a game in which the winning probability of replay is set to be lower than that of a conventional gaming machine that realizes a so-called ceiling function to attract the player's interest. Will be able to. In addition, in games where the winning probability of replay is set to a low probability, it is possible to prevent the player from wasting the labor accumulated by continuing to update the count value even if winning a special bonus, The player's willingness to continue playing can be maintained for a long time.

  (2) Moreover, in the gaming machine of the present invention, as the replay, a first replay and a second replay having different symbol combinations indicating a winning form are set, and the lottery means includes the first replay and the first replay. In a game in which the winning probability of replay including 2 replays is set to the probability P1, an internal lottery is performed so that the first replay wins alone and the second replay wins with one of the bonuses. In a game in which the winning probability of replay including the first replay and the second replay is set to the probability P2, the second replay is won alone, and the first replay is overlapped with any of the plurality of types of bonuses. An internal lottery may be performed to win.

  In this way, in a game where the winning probability of the replay is set to a low probability, the symbol combination indicating the winning form of the second replay is displayed, thereby informing the player of the winning of the bonus definitely. In a game in which the winning probability of replay is set to a high probability, the winning combination of the first replay is displayed, and the winning of the bonus can be definitely notified to the player. That is, according to this aspect, the bonus winning is achieved by reversing the expectation for the bonus winning at the time of the first replay and the expectation for the bonus winning at the second replay according to the winning probability of the replay. It is possible to provide an unprecedented interface environment for notifying a player.

  (3) Further, in the gaming machine of the present invention, as the replay, a first replay and a second replay having different symbol combinations indicating a winning form are set, and the replay probability control means is configured to The control of changing the winning probability of the replay including the first replay and the second replay to a probability P3 higher than the probability P1 at the end of different predetermined bonus states, and the winning probability of the replay becomes the probability P3 Updating the count value C2 by a fixed value for each game in the set state, and changing the winning probability of the replay to the probability P2 based on the count value C2 reaching the threshold value Cth2, Based on the first replay winning in a game in which the winning probability of the replay is set to the probability P3, In the control in which the update of the count value C2 is stopped and the winning probability of the replay is changed from the probability P3 to the probability P1, and the game in which the winning probability of the replay is set to the probability P3, the second replay wins On the basis of this, the updating of the count value C2 may be stopped and the winning probability of the replay may be changed from the probability P3 to the probability P2.

  In this way, depending on whether the first replay or the second replay is won in a game in which the winning probability of replay is set to a high probability, the winning probability of the replay in the subsequent game is low or high. Which is to be changed is determined. In this aspect, when the first replay and the second replay are not won even though the replay winning probability is set to a high probability, the replay winning probability is set to a high probability. Control to do. For this reason, in the predetermined number of games where the winning probability of replay is set to a high probability, the rare condition that the replay never wins is achieved, whereas the winning probability of replay in the subsequent game is high By setting to, a privilege can be given to the player and the player's interest can be further attracted.

  (4) In the gaming machine of the present invention, when the replay probability control means wins the special bonus in a game in which the winning probability of the replay is set to the probability P3, in the game after the winning of the special bonus Even when the first replay is won, the count value C2 may be updated until the count value C2 reaches the threshold value Cth2.

  In this way, winning of the special bonus guarantees that the winning probability of replay will be set to a high probability in subsequent games. Therefore, by giving the player a sense of purpose for winning the special bonus, Monotonization can be prevented.

  (5) Further, the present invention provides a gaming machine in which a winning combination is displayed based on a combination of symbols indicating a winning combination of winning combinations being displayed in a stopped state of a plurality of reels in which a plurality of types of symbols are arranged on the outer peripheral surface. For a plurality of types including a small role in which a game medium is paid out in accordance with a prize and a replay in which a next game is performed without requiring a game medium in accordance with a prize. A lottery means for performing an internal lottery, a reel control means for performing a control for rotating the plurality of reels, and a control for stopping the plurality of reels according to an internal lottery result, a normal state, and a prize for the small role A game state transition control means for controlling the transition of the game state between a plurality of types of bonus states having a higher rate than the normal state, and a predetermined variation opportunity for the winning probability of replay in the internal lottery As the control to move, the count value C1 is updated by a certain value for each game in the state where the winning probability of the replay is set to the probability P1, and the count value C1 reaches the threshold value Cth1, The computer of the gaming machine is caused to function as a replay probability control means for performing control for changing the winning probability of replay to a probability P2 higher than the probability P1, and the lottery means performs the small role and the replay in the internal lottery in the normal state. In addition, it is determined whether or not a plurality of types of bonuses that trigger the transition to the respective bonus states, and at least one of the plurality of types of bonuses is set as a special bonus, and the replay probability control means However, in the game where the winning probability of the replay is set to the probability P1, other than the special bonus -When the eggplant wins or wins, even if the count value C1 does not reach the threshold value Cth1, the updating of the count value C1 is stopped to change the winning probability of the replay, and the replay When the special bonus is won in a game in which the winning probability is set to the probability P1, the count value C1 is not changed until at least the special bonus state that shifts with the winning of the special bonus is completed. The count value C1 is updated on the condition that the threshold value Cth1 has not been reached, and the count value C1 remains until a bonus other than the special bonus is won or won even in the game after the end of the special bonus state. A program that continues to update the count value C1 on condition that the threshold value Cth1 has not been reached. It is about lamb.

  The present invention also relates to an information storage medium that can be read by a computer and stores a program that causes the computer to function as a state specification means.

  In the program and the information storage medium according to the present invention, each aspect shown in the above (2) to (4) can be appropriately adopted, and the computer functions as the means shown in (2) to (4). May be.

  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim.

One is arranged. The first reel R1 to the third reel R3 are pivotally supported by a step motor (reel driving means: not shown), and are each driven to rotate around the axis of the step motor. By controlling the width or the like, it is possible to stop in units of frames (a predetermined rotation angle unit, a predetermined rotation amount unit). That is, in the gaming machine of the present embodiment, when the step motor rotates and drives the first reel R1 to the third reel R3 in accordance with the drive pulse supplied from the control board, and the supply of the drive pulse from the control board is interrupted, As the rotation of the step motor stops, the first reel R1 to the third reel R3 stop.

  The front upper door UD and the front lower door DD are provided so as to be individually openable and closable, and the front upper door UD has a display window DW that allows observation of the rotation state and the stop state of the first reel R1 to the third reel R3. Is provided. In the stopped state of the first reel R1 to the third reel R3, three (three frames) of a plurality of types of symbols arranged at regular intervals on the outer peripheral surfaces of the first reel R1 to the third reel R3. The symbols (upper symbol, middle symbol, lower symbol) can be observed from the front of the gaming machine through the display window DW. The player's game result is determined by a combination of symbols stopped and displayed on the four effective lines L1 to L4 in the display window DW, and the combination of symbols on the effective line corresponds to a predetermined combination. In the case of, medals are paid out from the hopper unit as the winning combination.

  Note that in the gaming machine of this embodiment, it is possible to insert (bet) medals up to 2 or 3 for one game, and insert medals necessary for one game according to the game state. The number of sheets is set to be variable. The valid lines L1 to L4 are validated on the condition that medals corresponding to the number of medals inserted in one game (a prescribed number of medals) are inserted. Note that the line to be activated may be varied according to the number of inserted medals (the number of bets).

  The front upper door UD is provided with a game information display section DS. The game information display section DS is composed of an LED, a lamp, a 7-segment display, etc., and displays various game information such as the number of medals credited, the number of medals paid out or earned in one game, and the number of remaining bonus games. The

  In addition, the front upper door UD is provided with a liquid crystal display LCD for performing game effects. On the liquid crystal display LCD, various videos (or images) for assisting the game or for exciting the game are displayed. Further, in the gaming machine of the present embodiment, a plurality of speakers (not shown) for performing a game effect are provided for the front upper door UD and the front lower door DD. From the speaker, various sounds for assisting the game or for exciting the game are output.

  The front lower door DD is provided with various operation means. As the operation means, a bet button B0 (an example of an insertion operation means) for performing an operation for putting a stored medal into an insertion state, and the first reel R1 to the third reel R3 are rotated to trigger a game. A start lever SL (an example of a game start operation means) for performing an operation, and a stop button B1 for performing an operation that triggers each of the first reel R1 to the third reel R3 being rotated by a step motor. To B3 (an example of a stop operation means) are provided.

  In the gaming machine of the present embodiment, the player is set in a ready state in which a game can be started by inserting a medal into the medal insertion slot MI or performing an operation of pressing the bet button B0. When the player depresses the start lever SL, an internal lottery using a random number value is performed on the control board, and the first reel R1 to the third reel R3 start rotating by driving the step motor, and the first reel The pressing operation of the stop buttons B1 to B3 is permitted (validated) on condition that the rotation speed of the R1 to the third reel R3 has increased to a predetermined speed and a predetermined standby time (wait time) has elapsed. .

  Thereafter, when the player presses down the stop buttons B1 to B3 at an arbitrary timing, stop switches (stop signal output means: for example, a photo sensor, a continuity sensor, a pressure) built in each of the stop buttons B1 to B3 A sensor or the like) performs an ON operation, and changes a reel stop signal input to the control board from the OFF state to the ON state.

  When the player releases the stop buttons B1 to B3 that are in the pressed state at an arbitrary timing, the stop switch of each button is turned off, and the reel stop signal input to the control board is changed from the on state to the off state. .

  And the control board is a stop position according to the result of the internal lottery based on the change from the OFF state to the ON state of the reel stop signal whose signal state changes according to the pressing timing and release timing of the stop buttons B1 to B3. The first reel R1 to the third reel R3 are stopped.

  Further, a medal payout opening MO and a medal tray MP are provided at the lower part of the front lower door DD, and a number of medals according to the game result are paid out from the medal payout opening MO to the medal tray MP. Yes.

  FIG. 2 is a functional block diagram of the gaming machine of the present embodiment.

  The gaming machine of this embodiment is controlled by the game control means 100. The game control means 100 receives input signals from input means such as the medal insertion switch 210, the bet switch 220, the start switch 230, the stop switch 240, etc., and performs various calculations for executing the game, and based on the calculation results. Thus, operation control of output means such as the reel unit 310, the hopper unit 320, the display device 330, the speaker 340, and the like is performed. The functions of the game control means 100 are realized by various processors (CPU, DSP, etc.), ASIC (gate array, etc.), ROM (an example of an information storage medium), or hardware such as RAM, or software comprising a given program. Is done.

  The game control means 100 includes a random number generation means 110, a lottery table selection means 120A, a lottery means 120B, a flag setting means 120C, a reel control means 130, a winning determination means 140, a payout control means 150, a replay processing means 160, and a game state transition. It includes a control means 170, an effect control means 180, and a storage means 190.

  The random number generation means 110 is a means for generating random numbers for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts numerical values so as to circulate a predetermined count range). In this embodiment, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are irregular. Includes a value that can function as a random number.

  The lottery table selection unit 120A determines which lottery table to use for the internal lottery among a plurality of lottery tables stored in the lottery table storage unit 191 of the storage unit 190. In the gaming machine of the present embodiment, a plurality of types of gaming states such as a normal state, a bonus establishment state, a bonus state, etc. can be set, and the storage means 190 has a lottery table for internal lottery in each gaming state. It is remembered. In the lottery table for each gaming state, it is necessary to replay each of a plurality of random values (for example, 65536 random values from 0 to 65535) (replay: no need to insert medals in the next game with winning) Becomes a role: normal replay, special replay), small role (a role in which a predetermined number of medals are paid out when winning a prize: red cherry, blue cherry, special small role 1, special small role 2, normal bell, special bell) , And a bonus (a role that triggers the transition to the bonus state) or any of various combinations or loses. In this embodiment, the first big bonus (RBB1: an example of a bonus other than a special bonus), the second big bonus (RBB2: an example of a bonus other than a special bonus), and a third big bonus (CBB: a special bonus) are used as bonuses. 3 types of bonuses are prepared, and as each bonus is won, the first big bonus state (RBB1 state), the second big bonus state (RBB2 state), and the third big bonus state (CBB state) It has come to move to.

  In the present embodiment, the lottery table selecting unit 120A performs control to change the winning probability of at least one of the normal replay (first replay) and the special replay (second replay) in the internal lottery at a predetermined change timing. Replay probability control means 122 is included. Here, the lottery table storage unit 191 corresponds to the same gaming state for lottery tables having the same winning probability of the roles other than the normal replay and the special replay, and different in only the winning probability of at least one of the normal replay and the special replay The replay probability control means 122 stores a plurality of lottery tables that have different winning probabilities for at least one of normal replay and special replay as a predetermined change opportunity comes. By switching the lottery table used in the internal lottery, control is performed to increase or decrease the winning probability of at least one of normal replay and special replay. In the present embodiment, as a change opportunity for changing the winning probability of at least one of the normal replay and the special replay, a change opportunity linked with the game state transition opportunity and a change opportunity not linked with the game state transition opportunity are set. Yes.

  In the gaming machine of this embodiment, as shown in FIG. 3, the replay probability control means 122 adds the winning probability of the normal replay and the winning probability of the special replay at the first activation (at the first power-on to the gaming machine). Control is performed to set the winning probability (referred to simply as “replay probability”) of the entire replay to the probability P2 (approximately 1 / 1.7).

  In addition, as shown in FIG. 3, the replay probability control means 122 determines that the gaming state is RBB1 based on winning the first big bonus (RBB1) or the second big bonus (RBB2) in the internal lottery in the normal state. When the state or the RBB2 established state is entered, control is performed to set the replay probability to a probability P4 (about 1 / 2.5). That is, the replay probability control means 122 performs control to vary the replay probability by using a winning of a bonus different from the third big bonus (CBB) in the internal lottery in the normal state as a change opportunity.

  Further, as shown in FIG. 3, the replay probability control means 122 performs control to set the replay probability to the probability P5 (0) based on the first big bonus winning or the second big bonus winning. In other words, the replay probability control means 122 has a symbol combination indicating a winning pattern of the first big bonus different from a symbol combination indicating the winning pattern of the third big bonus in the stopped state of the first reel R1 to the third reel R3, or the second combination. Control is performed to change the replay probability by using the symbol combination indicating the big bonus winning pattern being displayed. In the gaming machine according to the present embodiment, in the first big bonus state and the second big bonus state, the replay probability is the probability P5 (0), so that the replay is not set for the internal lottery.

  As shown in FIG. 3, the replay probability control means 122 sets the replay probability to the probability P3 (about 1 / 1.1) with the end of the first big bonus state (RBB1 state) as a change trigger, and the second Control is performed to set the replay probability to the probability P2 (about 1 / 1.7) with the end of the big bonus state (RBB2 state) as a change trigger. That is, the replay probability control means 122 performs control to change the replay probability with the end of the bonus state different from the third big bonus state as a change trigger.

  In addition, as shown in FIG. 3, the replay probability control means 122 is based on a predetermined number of games (for example, five times) in which the replay probability after the end of the first big bonus state is set to the probability P3. Then, the control for changing the replay probability to the probability P2 (about 1 / 1.7) is performed.

  More specifically, the replay probability control means 122 first sets an initial value (for example, 5) of the count value C2 in the game number storage means 196 when the first big bonus state ends. Next, the replay probability control means 122 decrements and updates the count value C2 by a constant value (for example, by 1) for each game in a state where the replay probability is set to the probability P3 (about 1 / 1.1). Then, the updated count value C2 is stored in the game number storage means 196. Then, based on the fact that the count value C2 stored in the game number storage means 196 has reached the threshold value Cth2 (for example, 0), the replay probability control means 122 sets the replay probability to the probability P2 (about 1/1. Control to change to 7) is performed.

  Also, as shown in FIG. 3, the replay probability control means 122 determines the replay probability when a normal replay is won in a game in which the replay probability after the end of the first big bonus state is set to the probability P3. If the special replay is won by changing to P1 (about 1 / 7.3), the replay probability is controlled to change to probability P2 (about 1 / 1.7). At this time, the replay probability control means 122 counts the count value C2 stored in the game number storage means 196 based on one of the normal replay and special replay winning in the game whose replay probability is set to the probability P3. Is cleared (for example, set to 0), the update of the count value C2 is stopped.

  In addition, as shown in FIG. 3, the replay control means 122, when a bonus (RBB1, RBB2, CBB) is won in a game in which the replay probability is set to a probability P3 (about 1 / 1.1) Different controls are performed depending on the type of bonus selected.

  Specifically, in a game where the replay probability is set to the probability P3 (about 1 / 1.1), if RBB1 or RBB2 is won, the count value C2 is counted even if it does not reach the threshold value Cth2. By clearing the value C2, the updating of the count value C2 is stopped and the replay probability is controlled to change to the probability P4 (about 1 / 2.5). In addition, when a CBB is won in a game in which the replay probability is set to the probability P3 (about 1 / 1.1), the count value C2 is set at least until the CBB state that shifts with the CBB winning is completed. The count value C2 is continuously updated on condition that the threshold value Cth2 has not been reached. At this time, even if the normal replay is won in the game after winning the CBB, the replay probability control means 122 updates the count value C2 until the count value C2 reaches the threshold value Cth2, thereby obtaining the count value. Based on the fact that C2 has reached the threshold value Cth2, control is performed to change the replay probability to probability P2 (about 1 / 1.7).

  As described above, in the gaming machine of the present embodiment, the replay probability control means 122 has won the third big bonus (CBB), won the third big bonus (CBB), and ended the third big bonus state (CBB state). At an opportunity different from any of the above, control to stop the update of the count value C2 is performed.

  In addition, as shown in FIG. 3, the replay probability control means 122 is based on the fact that the game with the replay probability set to the probability P1 (about 1 / 7.3) has been performed a predetermined number of times (for example, 999 times). Then, control for changing the replay probability to the probability P2 (about 1 / 1.7) is performed.

  More specifically, the replay probability control means 122 first stores the number of game times triggered by a change in the replay probability from the probability P3 (about 1 / 1.1) to the probability P1 (about 1 / 7.3). In 196, an initial value (for example, 999) of the count value C1 is set. Next, the replay probability control means 122 decrements and updates the count value C1 by a fixed value (for example, by 1) for each game in a state where the replay probability is set to the probability P1 (about 1 / 7.3). Then, the updated count value C1 is stored in the game number storage means 196. The replay probability control means 122 then sets the replay probability to the probability P1 (about 1/7...) Based on the fact that the count value C1 stored in the game count storage means 196 has reached a threshold value Cth1 (eg, 0). Control to change from 3) to probability P2 (about 1 / 1.7) is performed.

  Further, as shown in FIG. 3, the replay control means 122, when a bonus (RBB1, RBB2, CBB) is won in a game in which the replay probability is set to a probability P1 (about 1 / 7.3) Different controls are performed depending on the type of bonus selected.

  Specifically, in a game in which the replay probability is set to the probability P1 (about 1 / 7.3), when RBB1 or RBB2 is won, the count is performed even if the count value C1 does not reach the threshold value Cth1. By clearing the value C1 (for example, setting it to 0), the updating of the count value C1 is stopped and the replay probability is controlled to change to the probability P4 (about 1 / 2.5). In addition, when a CBB is won in a game in which the replay probability is set to the probability P1 (about 1 / 7.3), the count value C1 is at least until the CBB state that shifts with the CBB winning is completed. The count value C1 is continuously updated on condition that the threshold value Cth1 has not been reached. At this time, even in the game after the end of the CBB state, the count value C1 is continuously updated on condition that the count value C1 has not reached the threshold value Cth1 until RBB1 or RBB2 is won. When the value reaches the threshold value Cth1, control is performed to change the replay probability to the probability P2 (approximately 1 / 1.7).

  As described above, in the gaming machine of the present embodiment, the replay probability control means 122 has won the third big bonus (CBB), won the third big bonus (CBB), and ended the third big bonus state (CBB state). At an opportunity different from any of the above, control to stop updating the count value C1 is performed.

  The lottery means 120B performs an internal lottery that determines whether or not a winning combination is based on a game start signal from a start switch 230 that is activated when the player presses a start lever SL (an example of a game start operation means).

  In the internal lottery, a random number value (random number for lottery) is acquired for each game based on a game start signal from the start switch 230, and the acquired random number value is stored in the lottery table storage unit 191 of the storage unit 190. It is determined whether or not the winning combination is won with reference to the lottery table.

  Based on the result of the internal lottery, the flag setting unit 120C changes the winning combination flag determined from the non-internal winning state (first flag state, off state) to the internal winning state (second flag state, on State), and the flag setting information is stored in the flag storage unit 192 of the storage unit 190. Also, in this embodiment, a flag that can carry on the internal winning state for the next game until the prize is won (carry-over possible flag) and a non-internal winning without carrying the internal winning state for the next game regardless of the winning. A flag to be reset to a state (carry-over impossible flag) is prepared. There are bonuses (the first big bonus, the second big bonus, and the third big bonus) that are associated with the former carry-over possible flag, and the other roles (for example, small role, replay, etc.) are the latter. It is associated with the carry-over impossible flag.

  Further, when the gaming state is the third big bonus state, the flag setting means 120C is associated with each of a plurality of types of small roles in each game regardless of the result of the internal lottery by the lottery means 120B. Process to set the flag is set to the internal winning state.

  The reel control means 130 steps the first reel R1 to the third reel R3 based on a game start signal from a start switch 230 that is actuated when the player depresses a start lever SL (an example of a game start operation means). In addition to performing control to rotate by the motor, control is performed to stop the first reel R1 to the third reel R3 that are rotationally driven by the step motor in accordance with the setting state of the flag (whether or not the winning combination).

  Then, the reel control means 130 is in a state in which the pressing operation (an example of the stop operation) with respect to the stop buttons B1 to B3 (an example of the stop operation means) is validated (in principle, the rotation of the first reel R1 to the third reel R3). In a state where the speed has reached a predetermined speed and a wait time is set, the fact that the wait time has elapsed may be an additional condition for validation) When the stop switch 240 is actuated by pressing B3, the supply of the drive pulse (motor drive signal) to the step motor of the reel unit 310 is stopped based on the reel stop signal from the stop switch 240. Control is performed to stop each of the reels R1 to R3.

  That is, the reel controller 130 determines the stop position of the reel corresponding to the pressed button of the first reel R1 to the third reel R3 each time the stop buttons B1 to B3 are pressed. The reel is stopped at the stop position. Specifically, referring to the stop control table stored in the stop control table storage unit 193 of the storage unit 190, the first reels R1 to R1 corresponding to the press timings of the stop buttons B1 to B3 (mode of stop operation) and the like. The stop position of the third reel R3 is determined, and control is performed to stop the first reel R1 to the third reel R3 at the determined stop position.

  In the stop control table, the position of each reel at the time of operation of the stop switch 240 according to the priority order determined for each combination in the table selected when two or more types of combination flags are set to the internal winning state. And the actual correspondence position of each reel is set. In particular, in this embodiment, the priority order is determined in the order of “Replay> Bonus> Board”. For example, in a table selected when both the replay and bonus flags are in the internal winning state, a replay winning is obtained. The stop position of each reel is set so that the symbols constituting the form are displayed on the active line in preference to the symbols constituting the bonus winning form. Also, for example, in the table selected when both the bonus and small role flags are in the internal winning state, the symbols constituting the bonus winning pattern are placed on the active line in preference to the symbols constituting the small role winning pattern. The stop position of each reel is set so as to be displayed. That is, the reel control means 130, when the flags relating to two or more types of winning combinations are set to the internal winning state, the symbols constituting the winning combination having a low priority according to the priority set for each winning combination. Control is performed so that the reels are stopped so that symbols constituting a combination with higher priority are displayed on the active line.

  The reel control means 130 performs so-called pull-in processing and kick-out processing as control for stopping the reel. The pull-in process is a control process for stopping the reel so that the symbol corresponding to the combination whose flag is set to the internal winning state is stopped on the active line (so that the winning combination can be won). On the other hand, the kicking process is a control to stop the reel so that the symbol corresponding to the combination whose flag is set to the non-internal winning state does not stop on the active line (so that the winning combination cannot be won). It is processing. That is, in the gaming machine of the present embodiment, in order to realize the above-described pull-in process and kick-off process, the flag setting state, the press timing of the stop buttons B1 to B3, the press order, the stop position of the reel that has already stopped (or the effective line) The stop control table is set so that the stop position of each reel changes according to the types of symbols stopped on L1 to L5. In this way, the reel control means 130 can stop the symbol of the combination for which the flag is set to the internal winning state in the form of winning, while the symbol of the combination for which the flag is set to the non-winning state is in the form of winning. Control is performed to stop the first reel R1 to the third reel R3 so as not to stop.

  In the gaming machine of the present embodiment, the reel unit 310 includes a reel index 315 made of a photosensor, and the reel control means 130 is based on a reference position signal detected by the reel index 315 every time the reel makes one revolution. Thus, the current rotation state of the reel can be monitored by obtaining the rotation angle (the number of rotation steps of the rotation axis of the step motor) from the reel reference position (the frame detected by the reel index). ing.

  In the gaming machine of this embodiment, in the stop control table for determining the stop position of each rotating reel, the number of frames required for each reel R1 to R3 to stop after the stop button B1 to B3 is pressed is determined. The upper limit is set to 5 frames (0 frame to 4 frames), and the reel control means 130 is an opportunity to stop the stop buttons B1 to B3 in the pull-in process and kick process regarding the first reel R1 to the third reel R3. Control is performed to stop the reel so that a symbol of a maximum of four frames ahead can be drawn from a frame located in the display window DW when the operation is performed. For this reason, in the gaming machine of the present embodiment, as shown in FIG. 4, for the first reel R1 to the third reel R3, a plurality of replay symbols 1 “RP” and replay symbols 2 arranged on the outer peripheral surface of each reel. “WM”, bell symbol “BL”, etc. are arranged so that the interval is within 5 frames, and when the replay is won or when the bell is won, the stop button B1 to B3 are pressed, the order of pressing, etc. Regardless of the arrangement, the replay symbol “RP” and the bell symbol “BEL” can be drawn on the active line.

  In the gaming machine of the present embodiment, when the gaming state is the third big bonus state (CBB state: an example of the special bonus state), the reel control means 130 sets the first reel R1 to the special control state, Control is performed to stop the first reel R1 uniformly within 75 msec from the timing of pressing the stop button (corresponding to the time required to rotate about one frame). That is, for the first reel R1 set to the special control state in the third big bonus state, the position within one frame from the position of the reel corresponding to the pressing timing of the stop button B1 corresponding to the first reel R1 is the stop position. A stop control table for the third big bonus state is set as determined.

  In the third big bonus state (CBB state), the reel control means 130 is within 190 ms from the timing of pressing the stop button B2 and the stop button B3 for the second reel R2 and the third reel R3 (approximately four frame rotations). In the stop control table for the third big bonus state, the symbol pull-in process and the kick-off process as described above are executed in the normal control state in which control is performed to stop each reel during the time required for movement). The stop positions of the second reel R2 and the third reel R3 are set so that they can be performed. Further, in this embodiment, since the replay probability at the time of winning the third big bonus is inherited even in the third big bonus state, when the replay is won by the internal lottery in the third big bonus state, the small role flag and the normal replay are played. Alternatively, both the special replay flag and the internal winning state may be set, but in the stop control table for the third big bonus state, the priority order of the symbols subject to the pull-in process is different from the above priority order, The stop position is set so as to have a relationship of “small role> replay”.

  The winning determination unit 140 performs processing for determining whether or not a winning combination has been won based on the stopped state of the first reel R1 to the third reel R3. Specifically, when all of the first reel R1 to the third reel R3 are stopped, referring to the winning determination table stored in the winning determination table storage unit 194 of the storage unit 190, each reel is stopped. It is determined whether or not the combination of symbols stopped on the active line is a predetermined winning combination.

  In the present embodiment, as shown in FIG. 4, the bonus symbol 1 “red 7”, the bonus symbol 2 “blue 7”, the outer peripheral surfaces of the first reel R1 to the third reel R3 constituting the reel unit 310, Cherry symbol 1 “red CH”, cherry symbol 2 “blue CH”, special symbol “FL”, bell symbol “BL”, replay symbol 1 “RP”, and replay symbol 2 “WM” are arranged. Then, depending on the combination of symbols displayed on the active line when each reel is stopped, as shown in FIG. 5, the first big bonus (RBB1), the second big bonus (RBB2), the third big bonus ( CBB), normal replay (first replay), special replay (second replay), red cherry, blue cherry, special small role 1, special small role 2, normal bell, and special bell, so that it can be determined whether or not a prize has been won A winning determination table is prepared. Note that “ANY” in the symbol combination indicating the red cherry and blue cherry winning patterns shown in FIG. 5 indicates that any symbol arranged on the outer peripheral surface of the reel may be used.

  In the gaming machine of the present embodiment, the winning process is executed based on the determination result of the winning determination means 140. As a process at the time of winning, for example, when a small role (normal bell, special bell, red cherry, blue cherry, special small role 1, special small role 2) wins, the payout control means 150 performs medal payout control processing. When a replay (normal replay, special replay) is won, the replay processing means 160 performs a replay process, and when a bonus (RBB1, RBB2, CBB) is won or a bonus state (RBB1 state, RBB2 state) , CBB state) is completed, a gaming state transition control process is performed by the gaming state transition control means 170 to transition the gaming state.

  The payout control means 150 performs payout control processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is set based on a predetermined number of payouts for each combination, and the set number of medals to be paid out is set to the hopper unit 320 (payout device). ) Is instructed. When a plurality of small combinations wins in one game, the total number of payouts for each small combination won is set as the number of medals to be paid out in the game.

  The hopper unit 320 performs an operation of paying out medals of the payout number instructed by the payout control means 150. The hopper unit 320 is provided with a payout medal detection switch 325 that operates every time a medal is paid out. The payout control means 150 is actually operated from the hopper unit 320 based on an input signal from the payout medal detection switch 325. It is configured to be able to manage the number of medals paid out.

  If credits (internal storage) of medals are permitted, instead of actually paying out medals by the hopper unit 320, the number of credits stored in a credit storage area (not shown) of the storage unit 190 (not shown) A credit addition process of adding the payout number to the credited medal number) is performed to virtually pay out the medal. In addition, when a replay (normal replay, special replay) or bonus (RBB1, RBB2, CBB) is won as a result of the game, no payout number is set, and therefore no medals are paid out from the hopper unit 320. However, a process (0 sheet process) is performed in which formally 0 medals are paid out.

  The replay processing means 160, when a normal replay or a special replay wins, does not require the insertion of a medal owned by the player for the next game, and sets the same preparation state as the previous game (replay processing (regame processing) )I do. That is, in the gaming machine of the present embodiment, when the normal replay or special replay is won, the same number of medals as the previous game are automatically used without using the player's own medals (including credit medals). The automatic insertion process set to the insertion state is performed, and the next game start operation (operation of pressing the start lever SL by the player) is waited with the same active line as the previous game being validated.

  Further, the gaming state transition control means 170 performs a gaming state transition control process for transitioning the gaming state between the normal state, various bonus establishment states, and various bonus states based on the establishment of a predetermined transition condition. As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. When a plurality of conditions are defined, transitioning a gaming state to another gaming state based on the fact that one of the plurality of conditions is satisfied or all of the plurality of conditions are satisfied Can do.

  In the gaming machine of this embodiment, the first big bonus state (RBB1 state), the second big bonus state (RBB2 state), and the third big bonus state (CBB state) can be set as the bonus state. In bonus games in each bonus state, control is performed so that the winning rate of the small role is higher than in the normal state. That is, in the RBB1, RBB2, and CBB states, it is easier to obtain more medals in a shorter period than in the normal state, and the gaming state (special state, bonus state) is advantageous to the player.

  The RBB1 state (an example of a bonus state) is a combination of symbols “Red 7 • indicating a winning pattern of the RBB1 in an RBB1 established state (an example of a bonus established state) that is shifted by winning the first big bonus (RBB1) in the internal lottery. The gaming state is shifted to when triggered by the display of “Red 7 / Red 7”. In the RBB1 state, in a bonus game, when a medals exceeding a predetermined number (360 or less, for example, 350) is paid out, the ending condition is satisfied and the ending condition is satisfied. Is controlled to shift the gaming state to the normal state (replay probability is probability P3: about 1 / 1.1).

  In the RBB2 state (an example of the bonus state), the symbol combination “blue 7 • indicating the winning form of the RBB2 in the RBB2 established state (an example of the bonus established state) that shifts by winning the second big bonus (RBB2) in the internal lottery. The gaming state is shifted to when triggered by the display of “blue 7 / blue 7”. In the RBB2 state, in a bonus game, when a medal exceeding a predetermined number (360 or less, for example, 290) has been paid out, is an end condition, and the end condition is satisfied. Is controlled to shift the gaming state to the normal state (replay probability is probability P2: about 1 / 1.7).

  In the RBB1 state and the RBB2 state, control is performed so that the player can repeatedly shift to the regular bonus state (RB state) in which the winning combination probability of the small combination is increased by increasing the type of small combination and the winning probability of the small combination. . The RB state is a gaming state in which one of a predetermined number of times (12 times) of bonus games and a predetermined number of times (8 times) of winnings in the bonus game is achieved. In the RBB1 state and the RBB2 state, control is performed so that the RB state can be repeatedly repeated until more than a predetermined number of medals are paid out. Thus, it can be said that the RBB1 state and the RBB2 state are game states (bonus states) that are advantageous to the player because many medals can be easily acquired in a short period of time compared to the normal state.

  In the CBB state (an example of the bonus state), the symbol combination “red 7 • indicating the CBB winning pattern in the CBB establishment state (an example of the bonus establishment state) that shifts by winning the third big bonus (CBB) in the internal lottery. The gaming state is shifted to when triggered by the display of “Red 7 / Blue 7”. In the CBB state, when the bonus game is set as an end condition when a predetermined number of medals exceeding a predetermined number (253 or less, for example, 150) are paid out, and the end condition is satisfied. Control is performed to shift the gaming state to the normal state (the replay probability is the same probability as when CBB was won).

  In the CBB state, the challenge bonus state (CB state) in which the first reel R1 is set to the special control state, the second reel R2 and the third reel R3 are set to the normal control state, and the bonus game is performed (CB state) is completed. It is controlled to operate continuously until the condition is satisfied. In the CB state, control for increasing the winning combination probability of the small combination is performed by setting all the small combination flags to the internal winning state regardless of the result of the internal lottery performed by the lottery means 120B. In this way, in the CBB state, control is performed so that the CB state continues until medals exceeding a predetermined number are paid out. Therefore, in the CBB state, it is easier to acquire more medals in a shorter period than in the normal state. Therefore, it can be said that the game state (bonus state) is advantageous for the player. In the gaming machine of the present embodiment, even in the CB state, the internal lottery is performed so as to determine whether or not the normal replay and the special replay are successful, and the winning probability is determined by the replay probability control means 122 when the CBB is won. It is controlled to be the same.

  The effect control means 180 uses a display device 330 (an example of an effect device) such as a lamp, LED, or liquid crystal display based on the effect data selected with reference to the effect table stored in the effect table storage means 195. Control relating to the sound effect to be performed using the display effect to be performed and the speaker 340 (an example of the effect device) is performed. Specifically, a lamp or LED is turned on or blinked according to the occurrence of a gaming event such as insertion of a medal, operation on the bet button B0, start lever SL, stop buttons B1 to B3, or a change in gaming state, or a liquid crystal display By changing the display content of the LCD or by outputting sound from the speaker 340, effect control for exciting the game or assisting the game is performed.

  Note that the functional block configuration of the present embodiment can also be applied to a computer system (including a game system). In these systems, the function is realized by downloading a program that causes the computer to function as the game control means 100 of the present embodiment from an information storage medium such as a CD or DVD or a Web server on the Internet via a network. be able to. In the above computer system, the medal insertion switch 210, the bet switch 220, the start switch 230, the stop switch 240 and the like virtually function their functions with respect to operation means such as a keyboard, a pointing device (mouse, etc.), or a controller. This can be realized by assigning. In the computer system, the reel unit 310, the hopper unit 320, and the like are not indispensable constituent elements, and these device units virtually function their functions by controlling images displayed on the display (display device 330). Can be realized.

2. Next, a control method employed in the gaming machine of the present embodiment will be described in detail with reference to FIGS. 6 and 7.

  First, in the present embodiment, the gaming state is set to the normal state A in the initial setting. In the normal state A, the lottery table in which the replay probability is set to the probability P2 (about 1 / 1.7) is set as the lottery table for internal lottery.

  Next, when RBB1 is won in the internal lottery in the normal state A, the gaming state shifts to the RBB1 established state, as indicated by F1 in FIG. Further, when RBB2 is won in the internal lottery in the normal state A, the gaming state shifts to the RBB2 established state as indicated by F2 in FIG. When the CBB is won in the internal lottery in the normal state A, the gaming state shifts to the CBB establishment state A as indicated by F3 in FIG.

  Here, in the RBB1 established state, the RBB2 established state, and the CBB established state A, the lottery table in which each bonus is excluded from the internal lottery due to any of RBB1, RBB2, or CBB being won, Set as a lottery table. Further, in the lottery table for the RBB1 established state and the lottery table for the RBB2 established state, the replay probability is changed so that the replay probability varies from the probability P2 (about 1 / 1.7) to the probability P4 (about 1 / 2.5). The relationship with the numerical value is set. Further, in the lottery table for the CBB establishment state A, the replay probability is maintained at the same probability P2 (about 1 / 1.7) as the winning probability in the internal lottery in the normal state A.

  Then, when RBB1 is awarded in the RBB1 established state, the gaming state shifts to the RBB1 state as indicated by F4 in FIG. In addition, when RBB2 is won in the RBB2 established state, the gaming state shifts to the RBB2 state as indicated by F5 in FIG. Further, when CBB is won in the CBB establishment state A, the gaming state shifts to the CBB state A, as indicated by F6 in FIG.

  Here, in the RBB1 state and the RBB2 state, the replay probability is set to the probability P5 (0) by setting the lottery table in which the replay is excluded from the internal lottery targets in accordance with the bonus winning that becomes the transition trigger of each state. ). Further, in the CBB state A, following the CBB establishment state A, the replay probability is maintained at the same probability P2 (about 1 / 1.7) as the winning probability in the internal lottery in the normal state A.

  Then, when medals exceeding a predetermined number (for example, 350) are paid out in the RBB1 state, the termination condition for the RBB1 state is satisfied. At this time, in the present embodiment, control for changing the replay probability is performed at the end of the RBB1 state, and when the RBB1 state ends, the replay probability is determined from the probability P4 (0) as shown in F7 in FIG. The game state is shifted to the normal state B by changing to P3 (about 1 / 1.1).

  Further, when medals exceeding a predetermined number (for example, 290) are paid out in the RBB2 state, the termination condition for the RBB2 state is satisfied. At this time, in the present embodiment, control for changing the replay probability is performed at the end of the RBB2 state, and when the RBB2 state ends, the replay probability is determined from the probability P4 (0) as shown in F8 in FIG. The game state is returned to the normal state A by changing to P2 (about 1 / 1.7).

  Further, when a medal exceeding a predetermined number (for example, 150) is paid out in the CBB state A, the termination condition for the CBB state A is satisfied. At this time, in the present embodiment, control is performed so that the replay probability is continuously maintained even when the CBB state A ends, and when the CBB state A ends, the gaming state is changed to the normal state A as shown in F9 of FIG. Return.

  Next, when RBB1 and RBB2 are won in the internal lottery in the normal state B, as shown in F10 and F11 in FIG. 6, the game is the same as in the case of winning RBB1 and RBB2 in the internal lottery in the normal state A. When the state shifts to the RBB1 established state or the RBB2 established state, the replay probability changes from the probability P3 (about 1 / 1.1) to the probability P4 (about 1 / 2.5) triggered by the winning of RBB1 or the winning of RBB2. Fluctuating control is performed.

  In addition, when CBB is won in the internal lottery in the normal state B, control is performed to maintain the replay probability at the probability P3 (about 1 / 1.1). As shown in F12 of FIG. Transition to the established state B. Then, when CBB is won in the CBB establishment state B, the gaming state shifts to the CBB state B and the replay probability is the same probability P3 as the winning probability in the internal lottery in the normal state B, as shown at F14 in FIG. (About 1 / 1.1).

  By the way, in the present embodiment, in a game in which the replay probability is set to the probability P3 (about 1 / 1.1), the game performs a count value C2 (initial value is, for example, 5) corresponding to the number of games. A control is performed to update the decrement every time it is detected, and a method of changing the replay probability triggered by the count value C2 reaching a predetermined threshold value Cth2 (for example, 0) is adopted. Therefore, in the normal state B, when the count value C2 that is decremented for each game reaches the threshold value Cth2, as shown in F13 of FIG. 6, the gaming state is returned to the normal state A, Control to change the replay probability to probability P2 (about 1 / 1.7) is performed.

  Further, in the present embodiment, in the normal state B, a method is adopted in which the replay probability is changed in response to the normal replay winning. Therefore, in the normal state B, when the symbol combination “RP / RP / RP” indicating the normal replay winning pattern is displayed on the active line, the updating of the count value C2 is stopped and F16 in FIG. As shown in FIG. 4, the game state is shifted to the normal state C, and the control for changing the replay probability to the probability P1 (about 1 / 7.3) is performed.

  Further, in the present embodiment, in the normal state B, a method of changing the replay probability triggered by the special replay winning is employed. For this reason, in the normal state B, when the symbol combination “WM / WM / WM” indicating the special replay winning pattern is displayed on the active line, the updating of the count value C2 is stopped and F13 in FIG. As shown in FIG. 2, the game state is returned to the normal state A, and the replay probability is controlled to change to the probability P2 (about 1 / 1.7).

  As described above, according to the control method of the present embodiment, depending on whether the normal replay or the special replay is won in the normal state B, the replay probability in the subsequent game is the probability P1 (about 1 / 7.3) or the probability P2 (about Which of 1 / 1.7) will be determined. In the normal state B, even if the winning probability of the normal replay and the special replay is set to a high probability, if neither the normal replay nor the special replay wins, the replay probability is set to a high probability. Control to set. For this reason, in the game of the predetermined number of times (for example, 5 times) in which the winning probability of both the normal replay and the special replay is set to a high probability, the rare condition that none of the replays are won is achieved. By setting the replay probability in the subsequent game to a high probability, it is possible to give a privilege that is highly unexpected to the player and further attract the player's interest.

  In the present embodiment, when the RBB1 or RBB2 is won in the normal state B, the update of the count value C2 is stopped as the gaming state shifts to the RBB1 established state or the RBB2 established state. When the CBB is won in the normal state B, the count value C2 is continuously updated until the count value C2 reaches the threshold value Cth2 even if the normal replay is won in the game after the CBB is won. The method is adopted.

  For this reason, when the count value C2 updated in the CBB establishment state B reaches the threshold value Cth2 without CBB winning in the CBB establishment state B, as shown in F15 of FIG. Control is performed to shift the gaming state to the CBB establishment state A and to change the replay probability to P2 (about 1 / 1.7). Further, when CBB is won in a game where the count value C2 reaches the threshold value Cth2 in the CBB establishment state B, the game state is shifted to the CBB state A and the replay probability is increased as shown in F18 of FIG. Control is performed to vary to P2 (about 1 / 1.7). If the CBB wins before the count value C2 calculated from the start point of the normal state B reaches the threshold value Cth2, and the CBB state B is entered, the update is performed even in the CBB state B. Based on the count value C2 being reached reaching the threshold value Cth2, as shown in F19 of FIG. 6, the gaming state is shifted to the CBB state A, and the replay probability is set to P2 (about 1 / 1.7). ) Is controlled.

  As described above, according to the control method of the present embodiment, the CBB winning in the internal lottery in the normal state B ensures that the replay probability is set to a high probability in the subsequent game. The game can be prevented from becoming monotonous by giving a sense of purpose to the game.

  Next, when RBB1 and RBB2 are won in the internal lottery in the normal state C, as shown in F20 and F21 in FIG. 6, when the RBB1 and RBB2 are won in the internal lottery in the normal state A and the normal state B Similarly, when the gaming state shifts to the RBB1 established state or the RBB2 established state, the replay probability is increased from the probability P1 (about 1 / 7.3) to the probability P4 (about 1/2) triggered by the winning of RBB1 or the winning of RBB2. .5) is performed.

  Further, when CBB is won in the internal lottery in the normal state C, control is performed to maintain the replay probability at the probability P1 (about 1 / 7.3), and as shown in F22 of FIG. 6, the gaming state is CBB. Transition to the established state C. Then, when CBB is won in the CBB establishment state C, as shown in F23 of FIG. 6, the gaming state shifts to the CBB state C, and the replay probability is the same probability P1 as the winning probability in the internal lottery in the normal state C. (About 1 / 7.3).

  By the way, in the present embodiment, in a game in which the replay probability is set to the probability P1 (about 1 / 7.3), the game performs a count value C1 (initial value is, for example, 999) corresponding to the number of games. A control is performed to update the decrement every time it is received, and a method of changing the replay probability triggered by the count value C1 reaching a predetermined threshold value Cth1 (for example, 0) is adopted. Therefore, in the normal state C, when the count value C1 that is decremented and updated for each game reaches the threshold value Cth1, as shown in F24 of FIG. Control to change the replay probability to probability P2 (about 1 / 1.7) is performed.

  In the present embodiment, when RBB1 or RBB2 is won in the normal state C, the update of the count value C1 is stopped as the gaming state shifts to the RBB1 established state or the RBB2 established state. When the CBB is won in the normal state C, the count value C1 is set on the condition that the count value C1 has not reached the threshold value Cth1 until at least the CBB state C to which the CBB is won is completed. A method of continuously updating is adopted.

  For this reason, when the count value C1 updated even in the CBB establishment state C reaches the threshold value Cth1 without CBB winning in the CBB establishment state C, as shown in F25 of FIG. Control is performed to shift the gaming state to the CBB establishment state A and to change the replay probability to P2 (about 1 / 1.7). Further, when the CBB is won in the game where the count value C1 reaches the threshold value Cth1 in the CBB establishment state C, the game state is shifted to the CBB state A as shown in F26 of FIG. Control is performed to vary to P2 (about 1 / 1.7). Further, in the CBB state C, based on the fact that the count value C1 that has been updated in the CBB state C before reaching the end condition of the CBB state C has reached the threshold value Cth1, it is indicated by F27 in FIG. As described above, the game state is shifted to the CBB establishment state A, and the replay probability is controlled to vary to P2 (about 1 / 1.7). In the CBB state C, the game state is returned to the normal state A as shown in F28 of FIG. 6 based on the fact that the count value C1 has reached the threshold value Cth1 in the game in which the end condition of the CBB state C is satisfied. Thus, control is performed to change the replay probability to P2 (about 1 / 1.7). Further, in the CBB state C, when the count value C1 does not reach the threshold value Cth1 in the game in which the end condition of the CBB state C is satisfied, the game state is returned to the normal state C as shown in F29 of FIG. Control to maintain the replay probability at P1 (about 1 / 7.3). That is, in the present embodiment, in the game after the end of the CBB state C, the update of the count value C1 is continued on the condition that the count value C1 has not reached the threshold value Cth1 until RBB1 or RBB2 is won. .

  As described above, the control method of the present embodiment realizes a so-called ceiling function that performs control for changing the replay probability from a low probability to a high probability according to the count value C1 updated for each game. In the control method of the present embodiment, the count value C1 is updated every time a game with a low replay probability is performed, but if the RBB1 or RBB2 is won, the update of the count value C1 is stopped. When the CBB is won, the count value C1 is continuously updated. For this reason, even if the CBB is won in a game in which the replay probability is set to a low probability, the renewal probability is set to a low probability because the update of the count value C1 is not stopped when the CBB is won. It is possible to win CBB multiple times until a predetermined number of games (for example, 999 times) are played. Therefore, according to the control method of the present embodiment, the medal acquisition situation in a game in which the replay probability is set to a low probability is improved compared with a conventional gaming machine that realizes a so-called ceiling function, and attracts the player's interest. You can turn it on. Further, in a game where the replay probability is set to a low probability, it is possible to prevent the player from wasting the labor accumulated by continuing to update the count value C1 even if the CBB is won. The willingness to continue playing can be maintained for a long time.

  In this embodiment, the internal lottery is performed using the lottery table shown in FIG. 7 in the normal state A, the normal state B, and the normal state C shown in FIG. Here, in each lottery table, the winning probability of normal replay and the winning probability of special replay are different.

  First, in the lottery table for the normal state C in which the replay probability is set to the probability P1, the correspondence between the combination and the random number value so that the normal replay is won alone and the special replay is won together with bonuses (RBB1, RBB2, CBB). Relationship is set.

  Also, in the lottery table for the normal state A for setting the replay probability to the probability P2, the special replay is won alone and the normal replay is won with bonuses (RBB1, RBB2, CBB) and the combination of the combination and the random number value. Correspondence is set.

  Further, in the lottery table for the normal state B for setting the replay probability to the probability P3, both the normal replay and the special replay are won independently, and both the normal replay winning probability and the special replay winning probability are the normal state C. The correspondence between the combination and the random number value is set so as to be higher than in the case of the lottery table.

  In this embodiment, by using the lottery table as shown in FIG. 7 in the internal lottery, in the normal state C, the symbol combination “WM / WM / WM” indicating the special replay winning pattern is displayed on the active line. Thus, the player can be notified of the winning of the bonuses (RBB1, RBB2, CBB). On the other hand, in the normal state A, the winning combination of the bonus (RBB1, RBB2, CBB) can be definitely notified to the player by displaying the symbol combination “RP / RP / RP” indicating the winning form of the normal replay. it can. That is, according to the control method of the present embodiment, the winning of the bonus is achieved by reversing the expectation for the bonus winning at the time of the normal replay winning and the expectation for the bonus winning at the winning of the special replay according to the replay probability. By providing an unprecedented interface environment for notifying the player, it is possible to further attract the player's interest.

  The present invention is not limited to that described in the above embodiment, and various modifications can be made.

  For example, in the above embodiment, the case where two types of replays having different symbol combinations indicating the winning pattern are set as an example has been described. However, there is only one symbol combination indicating the winning type of replay. Or three or more types.

  Also, for example, in the above embodiment, the count value C1 and the count value C2 have been described by taking the case where the decrement is updated for each game, but the count value C1 and the count value C2 are incremented and updated for each game. Also good. In this case, it is possible to set the number of games as a threshold value Cth1 and Cth2 as conditions for changing the replay probability.

  In the above embodiment, a method of canceling the updating of the count values C1 and C2 triggered by the winning of RBB1 or RBB2 by changing the replay probability triggered by a bonus other than CBB such as RBB1 or RBB2 being won. However, in the winning of RBB1 and RBB2, the count values C1 and C2 are updated with the winning of RBB1 and RBB2 as a trigger by changing the replay probability with the winning of RBB1 and RBB2 without changing the replay probability. The method of stopping is also included in the scope of the present invention.

  Further, for example, in the above embodiment, the case where a plurality of types of bonus states can be set has been described as an example. However, the control method introduced in the above embodiment is a gaming machine in which only a single bonus state can be set. Are equally applicable.

  Also, for example, in the above embodiment, the case where one type of special bonus among a plurality of types of bonuses is described as an example, but two or more types of special bonuses may be prepared, and an internal lottery target Even when all the bonuses are treated as special bonuses, the control method introduced in the above embodiment can be equally applied.
