Description

  The present invention relates to a slot machine that generates a replay time after the end of a bonus game.

  Conventionally, for example, there is a slot machine that determines an internal winning combination by an internal lottery and gives a prize according to the determined internal winning combination. In such a slot machine, a bonus game can occur when a bonus combination determined as an internal winning combination wins. Furthermore, there is also known a slot machine that generates a replay time that increases the internal winning probability of the replay role when the bonus game ends.

  As a slot machine that generates a replay time, a plurality of types of regular bonus games (hereinafter referred to as RB games) are repeatedly generated while a BIG bonus game (hereinafter referred to as BB games) is generated, and an RB game that is terminated together with the BB game. There has been proposed a slot machine that generates different replay times depending on the type of the game (see, for example, Patent Document 1). In such a slot machine, the replay time that occurs after the end of the BB game is varied according to the progress of the BB game, so that the interest of the game during the occurrence of the BB game is maintained high.

  However, the conventional slot machine has the following problems. That is, if the type of the regular bonus combination (hereinafter referred to as RB combination) won immediately before the end of the BB game is stored, the type of replay time occurring after the end of the BB game can be easily determined, and the determination method thereof Is also monotonous, there is a possibility that the interest of the game during the occurrence of the BB game cannot be maintained high.

In order to maintain the player's tension for a long time until the end of the BB game, a method of continuously generating an RB game that ends in a short period can be considered. However, in this method, it is necessary to win the RB combination over and over, and the number of games required until the end of the BB game increases, which may cause dissatisfaction with the player.
Furthermore, in order to enhance the interest of the game during the occurrence of the BB game, a method of continuing the replay time that occurred in the middle of the BB game until after the end of the BB game is conceivable. However, winning the replay role during the occurrence of the BB game may be dissatisfied because there is no merit for the player just by prolonging the BB game.

JP 2007-236808 A

  The present invention has been made in view of the above-described conventional problems, and provides a slot machine that can maintain a high level of interest in a game during the occurrence of a bonus game in a slot machine that generates a replay time after the bonus game ends. It is something to try.

The present invention includes a symbol variation display means for variably displaying a plurality of types of symbols in a symbol display area according to a predetermined arrangement;
Game start operating means operated by the player to start the game;
An internal lottery is executed for determining an internal winning combination from a plurality of types in accordance with an operation on the game start operation means in a state where a game medium is inserted, and an internal winning corresponding to the determined internal winning combination Internal lottery means for establishing a flag;
A stop operation means operated by a player to stop the display of the variation of the symbol by the symbol variation display means;
Display control means for drawing a symbol corresponding to the internal winning flag in accordance with an operation on the stop operation means within a predetermined pull-in range and stopping and displaying the symbol on the symbol display area;
Winning determination means for determining whether or not the symbol stopped and displayed by the symbol variation display means is a predetermined winning symbol;
Profit granting means for granting a player a profit corresponding to the winning symbol when the winning determining unit determines that the winning symbol is a winning symbol;
In response to the winning of a predetermined special role, a special state in which a specific state in which the internal winning probability of at least one of the multiple types of roles is different from the normal state is repeatedly generated is generated, Special state generating means for terminating the special state when the number of payouts exceeds a predetermined prescribed number;
Specific state determining means for determining whether or not each game is in the specific state in the special state;
When the specific state determination unit determines that the specific state is not a specific state, the internal lottery unit includes a first specific state and a second specific state before the internal lottery unit executes an internal lottery according to an operation on the game start operation unit. Specific state lottery means for determining one of a plurality of specific states by lottery;
In the game in which the specific state lottery means determines the specific state by lottery, the determined specific state is generated before execution of the internal lottery by the internal lottery means, while the predetermined specific state end condition is satisfied A specific state generating means for terminating the specific state;
When one of the plurality of types of specific states ends and a new specific state does not occur, the replay role's internal winning probability may generate a replay time different from the normal state. RT generating means for ending the replay time according to establishment,
The RT generating means includes a first replay time that occurs when the first specific state ends and a second replay time that occurs when the second specific state ends. It is configured to generate any one, and the first replay time and the second replay time are different in at least one of the internal winning probability of the replay role and the RT end condition. The slot machine is characterized in that (Claim 1).

  In the slot machine of the present invention, the special state which is a gaming state in which any one of the plurality of types of specific states repeatedly occurs is set. Then, after the special state ends, the replay time in which the internal winning probability of the replay combination is different from the normal state may occur. The replay time includes at least the first replay time and the second replay time, and these two types of replay time are different in the internal winning probability of the replay role or the RT end condition.

  Whether the first replay time or the second replay time occurs following the special state is determined according to the type of the specific state that occurred at the end of the special state. The first replay time may occur when the first specific state ends with the end of the special state, and the second replay time may occur when the second specific state ends with the end of the special state. .

  The first replay time and the second replay time are different in at least one of the internal winning probability of the replay combination and the RT termination condition, and may influence the player's profit. Therefore, the type of the replay time that occurs following the special state can be a major concern for the player.

  Furthermore, in the slot machine of the present invention, the specific state lottery means determines the specific state to be generated in the special state by lottery. Therefore, in the special state generated by this slot machine, any one of the plurality of types of specific states may potentially occur, and the type of the specific state being generated cannot be accurately specified when viewed from the player side. It is like that. For example, if the type of specific state cannot be specified at all, the player's sense of tension can be maintained until the special state ends and a replay time actually occurs.

  As described above, according to the slot machine of the present invention, the player can be directed to play by guessing the type of the specific state during the occurrence of the special state, and the game during the occurrence of the special state High interest can be maintained.

The slot machine of the present invention may be a slot machine in a narrow sense using medals and coins as game media, or a parrot (R) using pachinko balls as game media.
Further, the RT generating means can be configured not to generate the replay time for any one of the plurality of types of specific states. In this case, a game pattern in which the replay time does not occur after the special state can be set, and the player's tension in the special state can be further enhanced.
Also, for example, if the RT end condition is made different between the first replay time and the second replay time, the player has a sense of tension that the replay time will not continue until after the replay time occurs. Can be made.

  In addition, the specific state end condition is that the number of digest games has reached a predetermined number of games that is prescribed in advance for each specific state, that the number of winning games has reached a predetermined number of winnings that is prescribed in advance for each specific state, and Preferably, at least one of the completion of the special state is satisfied (Claim 2).

Further, in the internal lottery means, it is preferable that an internal winning probability of at least one of a plurality of types of roles is different between the first specific state and the second specific state. .
In this case, according to the difference in the winning frequency of any of the roles in the special state or the difference in production according to the winning, the type of the specific state is continuously estimated during the occurrence of the special state. Players can be directed. Thereby, the interest of the game during the occurrence of the special state can be maintained high.

In the internal lottery means, there is a possibility that an internal winning is set in the first specific state, while a combination that is not internally won in the second specific state is set (Claim 4).
In this case, there is a possibility that the possibility of at least the second specific state can be denied due to the difference in the winning combination during the occurrence of the special state. Thus, useful hints for predicting the specific state can be obtained from the type of winning combination during the occurrence of the special state.

In addition, it comprises a rendering means for selectively executing any of a plurality of types of rendering during the occurrence of the specific state,
The production means is selected from the plurality of types of production according to the combination of the type of the previous specific state and the type of the specific state during the occurrence of the specific state for the second time or later in the special state. It is preferable to execute the effect (claim 5).

  In this case, when the production means performs some production, the player can predict the type of the specific state that is occurring based on the content of the production. In particular, the effect means selects an effect according to the combination of the type of the previous specific state and the type of the specific state that is occurring. Therefore, the player can enjoy the prediction of the specific state based on a comparatively long determination period of two specific state execution periods that occur before and after.

  Thus, the content of the effect performed by the effect means can be a big hint for predicting the type of the replay time that occurs after the end of the special state. It should be noted that the timing at which the effecting unit executes the effect can be more advantageous to the player side as it is closer to the end point of the special state. The number of times the production means executes the production may be one time, or may be a plurality of times such as two times.

In addition, it is preferable to include RT notification means for notifying whether or not to generate a replay time after the special state ends and RT information indicating the type of the replay time to be generated.
In this case, based on the RT information notified by the RT notification means, the player can know whether or not the replay time has occurred and its type. If various presentations for notifying the RT information are performed at various timings, it is possible to realize further various gaming characteristics.

Further, it comprises a remaining payout number counting means for counting the remaining payout number until the cumulative payout number of game media during the occurrence of the special state reaches the predetermined specified number,
Among the plural types of specific states, there is a specific state in which a minimum number of game media payouts is set,
Preferably, the RT notification means notifies the RT information when the remaining payout number is smaller than the minimum payout number when the specific state in which the minimum payout number is set is generated (Claim 7).
In this case, when the type of the replay time to be generated after the special state is completed, the RT notification unit notifies the RT information.

In addition, it is preferable that when the RT notification unit is determined to generate a replay time that is most advantageous to the player among a plurality of types of replay times, a notification to that effect is provided.
In this case, the player's expectation for the most advantageous replay time can be enhanced during the occurrence of the special state. The player can play the game in the special state with excitement as to whether or not the notification that the most advantageous replay time has been determined will occur.

Further, the special state generating means is configured to generate any one of a plurality of types of special states including a first special state and a second special state as the special state,
In the specific state lottery means, the probability that at least one of the plurality of types of specific states is determined by lottery is different between the first special state and the second special state. (Claim 9).

  In this case, the game patterns during the occurrence of the special state can be varied by making the winning probabilities of any specific state different for each type of the special state. Furthermore, the expectation level of the replay time that occurs following the special state can be made different according to the type of the special state. In this way, it is possible to realize a game with rich undulations, and to further enhance the interest of the game during the occurrence of the special state.

Example 1
In this example, the slot machine 1 generates a replay time following a bonus game in a special state. The contents will be described with reference to FIGS.
As shown in FIGS. 1 to 3, the slot machine of this example includes a symbol variation display means 2 for variably displaying a plurality of types of symbols in a symbol display area 110 according to a predetermined arrangement, and a player operating the game to start a game. In order to determine an internal winning combination from a plurality of types according to the operation of the game start operation means 62 (hereinafter referred to as start lever 62) and the start lever 62 in a state where a game medium (medal) is inserted. The internal lottery means 42 for establishing the internal winning flag corresponding to the determined internal winning combination, and the stop operation operated by the player to stop the symbol fluctuation display by the symbol fluctuation display means 2 Means 61 (hereinafter referred to as stop button 61) and a symbol corresponding to the internal winning flag in accordance with an operation on the stop button 61 Display control means 45 for drawing within the specified drawing range and stopping display in the symbol display area 110, and winning determination means for determining whether or not the symbol stopped and displayed by the symbol variation display means 2 is a predetermined winning symbol 49, and when the winning determination means 49 determines that the winning symbol is a winning symbol, the profit granting means 40 for giving the player a profit corresponding to the winning symbol, and the winning of a predetermined special role, A special state is generated in which a specific state in which the internal winning probability of at least one of the combinations is different from the normal state is repeatedly generated, while the special payout amount when the cumulative number of payouts in the special state exceeds a predetermined prescribed number Special state generating means 43 for ending the state, specific state determining means 44 for determining whether or not each game is in a special state in the special state, and specific state determining means 44 When it is determined that the state is not a state, before the internal lottery means 42 executes the internal lottery in response to an operation on the start lever 62, a plurality of types of specific states including the first specific state and the second specific state are included. The specific state lottery means 46 for determining one by lottery, and the specific state determined before the execution of the internal lottery by the internal lottery means 42 in the game in which the specific state lottery means 46 has determined the specific state by lottery On the other hand, when a specific state generation unit 48 that ends the specific state when a predetermined specific state end condition is satisfied, and when any one of a plurality of types of specific states ends and no new specific state occurs While the internal winning probability of the replay role can generate a replay time different from the normal state, the replay time ends when a predetermined RT end condition is met RT generating means 47 to be provided.

The RT generating means 47 provided in the slot machine 1 of this example includes a plurality of types including a first replay time that occurs when the first specific state ends and a second replay time that occurs when the second specific state ends Any one of the replay times. The RT end condition is different between the first replay time and the second replay time.
Hereinafter, this content will be described in detail.

  First, the playability of the slot machine 1 of this example will be described. The BIG bonus game (referred to as BB game as appropriate) in the special state in this example is a gaming state in which a REG bonus game (referred to as RB game as appropriate) in a specific state is repeatedly generated. In the slot machine 1 of this example, the first to third RB games are set as the specific state, and which RB game is generated during the generation of the BB game is determined by lottery. Unlike the slot machine in which the RB game is determined according to the occurrence of the winning combination, the slot machine 1 of this example determines the type of the RB game (specific state) that is occurring in the BB game as viewed from the player side. Is getting harder.

  Further, in the slot machine 1 of this example, the type of replay time that occurs after the end of the BB game differs depending on the type of RB game that occurred at the end of the BB game. The first replay time is selected corresponding to the first RB game in the first specific state, and the second replay time is generated corresponding to the second RB game in the second specific state, while the other specific state is in effect In the case of the third RB game, no replay time occurs. As described above, in the slot machine 1, whether or not the replay time is generated or the type of the replay time that is generated differs depending on the type of the RB game that has occurred at the end of the BB game. That is, the slot machine 1 of the present example has a game property that the player's degree of advantage differs depending on the progress of the BB game. In the game of the slot machine 1 of this example, the type of the RB game that is occurring in the BB game, in particular, the type of the RB game at the end of the BB game can be a concern for the player.

  Next, the combination, internal winning combination and winning combination of the slot machine 1 of this example will be described with reference to FIGS. In the slot machine 1 of this example, eight types of combinations including first and second BIG bonus combinations (hereinafter referred to as BB combinations) and small combinations such as plum combinations are set. FIG. 3 shows the names of the respective roles in the left column, the winning symbols that are combinations of symbols corresponding to the respective roles in the middle row, and the benefits (profits) given to the players according to the winnings in the right column. Show. In the slot machine 1, when a winning symbol corresponding to the internal winning combination is established along any of the winning lines, that combination becomes a winning combination.

  Note that the Plum combination among the small combinations can be won in the first RB game and the third RB game, but not in the second RB game. Also, the 15-card combination can be won only in the first to third RB games. The first BB combination is an opportunity for the first BB game in the first special state, and the second BB combination is an opportunity for the second BB game in the second special state. The first BB game and the second BB game have different RB game lottery probabilities.

  Next, the slot machine 1 of this example has an external configuration as shown in FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 includes a liquid crystal display unit 530, a pair of left and right speakers 520, and a decorative lamp unit 560 disposed on the upper side in the vertical direction of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed on the lower side in the vertical direction. On the right side of the symbol display window 11, a credit display unit 551 and a payout amount display unit 552 are arranged in the horizontal direction.

  As shown in FIG. 2, the base portion 100 is formed so as to protrude relatively toward the player with respect to the symbol display window 11 located deeper from the player side. The base portion 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 at the lower end, and the operation panel 13 between the operation surface 14 and the medal tray 15. Have.

  As shown in FIGS. 1 and 2, the operation surface 14 has a bet button 64 for betting a medal credited (stored) by a credit function, a settlement button 65 for paying out the credited medal, and a game A medal insertion slot 630 for inserting medals to bet on is arranged. On the operation panel 13, a start lever 62 for starting the symbol variation of the reel 21 and a stop button 61 for stopping the symbol variation are arranged.

  As shown in FIGS. 1 and 2, the bet button 64 is a button for designating 3 bets, which is the maximum bet number, as the number of game bets. The bet button 64 generates a 3-bet signal representing the number 3 of game bets. However, when the remaining credit is 2 or 1, a 2-bet signal or 1-bet signal is generated, and when the credit is zero, a bet signal is not generated.

  In the slot machine 1 which is a 3-bet dedicated machine, the start lever 62 is set to the valid state when a medal is directly inserted or when three medals are bet by operating the bet button 64. Instead of the slot machine 1 of this example, which is a so-called 3-bet dedicated machine for betting 3 medals for each game (game), a slot of a type in which the number of game bets can be selectively set according to the player's preference It may be a machine. In this case, it is preferable to provide a single bet button for generating a single bet signal in addition to a max bet button for generating a 3-bet signal.

As shown in FIGS. 1 and 2, the start lever 62 is an operation lever that generates a change start signal, which is a control signal for the reel 21, at the timing when the player operates.
The stop button 61 is an operation button that is generated at a timing when a player operates a variable stop signal that is a control signal of the reel 21. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  As shown in FIG. 2, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each symbol display area 110L, C, R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display areas for nine symbols arranged in a two-dimensional matrix of 3 rows and 3 columns are formed. The entire symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. For nine symbols 20 arranged in a two-dimensional matrix, winning lines 211 to 215, which are the arrangement direction of winning symbols, are set. As the winning lines, there are horizontal winning lines 211 to 213 and diagonal winning lines 214 and 215.

  On the back side of each symbol display area 110L, C, R, reels 21L, C, R constituting the symbol variation display means 2 are respectively arranged as shown in FIGS. The reels 21L, 21C, 21R are rotary reels having a substantially columnar shape and 21 symbols 20 arranged on the outer peripheral surface thereof with a substantially constant interval. Each reel 21L, C, R has a reference position piece (not shown) at one reference position in the rotation direction. The reference position piece is a member as a detected piece detected by a reference position detection unit 66 described later. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

The liquid crystal display unit 530 includes a liquid crystal display as shown in FIGS. The liquid crystal display unit 530 displays various effect screens for producing games.
The speaker 520 and the lamp unit 560 are rendering means for rendering a game with sound or light.
The credit display unit 551 is a display unit that displays the number of medals credited (stored) by the credit function.
The payout number display unit 552 is a display unit that displays the number of payout medals at the time of winning a prize.

  Next, the control board 3 for controlling the overall operation of the slot machine 1 and each part electrically connected to the control board 3 will be described with reference to FIGS. 1 and 2. For the control board 3, in addition to the above-described configuration, a inserted medal detection unit 63 that detects a medal inserted as a game medium, a reel drive unit 22 (design variation display means 2) that rotates the reel 21, and a reel 21. A reference position detection unit 66 for detecting the rotation position of each of them, a medal payout unit 54 for paying out medals, various display units 55 including a credit display unit 551 and a payout number display unit 552, a lamp control board 56 for controlling lighting of the lamp unit 560, A set value operation unit 68 for setting a set value representing the degree of advantage of the player, an audio control board 52 for controlling the speaker 520 (audio output unit), and a display control board 53 for controlling the liquid crystal display unit 530 are electrically connected. Has been.

  As shown in FIGS. 1 and 2, the inserted medal detection unit 63 is a detection unit for medals inserted from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion slot 630. Three insert signals correspond to a 3-bet signal. In the slot machine 1 of this example, which is a 3-bet dedicated machine, the start lever 62 is set to an effective state when a medal is inserted or when three bets are bet by operating the bet button 64.

  As shown in FIGS. 1 and 2, the reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is a driving unit that rotationally drives the reel 21 by the rotational driving force of the stepping motor. The stepping motor rotates one step each time a control pulse is taken from the control board 3. The reel drive unit 22 captures the variation start signal to start the rotation of the reel 21 and captures the variation stop signal to stop the reel 21.

As shown in FIG. 1, the reference position detection unit 66 is a detection unit that detects the passage of the reference position pieces of the reels 21L, 21C, and R, and outputs a detection signal.
The medal payout unit 54 is a payout unit that pays out medals to the medal tray 15 under the control of the control board 3.
The set value operation unit 68 is an operation unit for changing the set value for setting the winning probability of the bonus combination in six stages using the setting key 680.

  As shown in FIGS. 1 and 2, the control board 3 extracts a CPU 31, ROM 33 and RAM 34 as memory means, an I / O unit 32 as an input / output interface, and random numbers belonging to a range of 0 to 65535. And a random number extraction unit 35. The CPU 31 executes a software program read from the ROM 33 to thereby display a winning determination means 49 for determining a winning combination, a display control means 45 for controlling the reel 21, an internal lottery means for lottering an internal winning combination, and an internal winning flag. Winning flag control means 41 for controlling, profit granting means 40 for giving a player a profit according to a prize, special state generating means 43 for generating a BB game, remaining payout count for counting the remaining payout until the end of the BB game Means 431, specific state determination means 44 for determining whether or not each game is an RB game in the BB game, specific state lottery means 46 for determining any of the first to third RB games by lottery, and replay time RT generating means 47 for generating, specific state generating means 48 for selectively generating any RB game It is arranged to implement the functions.

  As shown in FIG. 1, the ROM 33 as the memory means has a winning random number table (see FIG. 5) used by the internal lottery means 42 for the lottery of the internal winning combination, and a winning random number table used by the specific state lottery means 46 for the RB game lottery. (See FIG. 6) and a stop table (not shown) used for stop control (retraction control) of the reel 21 is stored.

  As shown in FIG. 5, the winning random number table for drawing the internal winning combination is a data table in which the winning random numbers for winning each combination are defined. The winning random number table is prepared for each normal state, BB carryover state, replay time, gaming state such as each RB game, and for each set value. In the slot machine 1, the internal winning probability of any combination is changed according to the gaming state by switching the winning random number table applied to the lottery of the internal winning combination according to the gaming state. Further, by switching the winning random number table applied to the lottery of the internal winning combination for each set value, the internal winning probability of at least one of the combinations is changed according to the set value. In the figure, the BB role carry-over state means a gaming state after the BB role is won internally and until the BB role wins.

  FIG. 5 is a diagram exemplifying a winning random number table at a certain set value. In the replay time winning random number table, most of the lost winning random numbers are set as the winning random numbers for the replay role, while the winning random numbers for the BB role are not set. Therefore, the replay time is a gaming state in which the replay role can be won internally with a high probability, while the BB role is not likely to win internally.

  In the first to third RB games in the specific state, the winning random numbers for the replay role and the BB role are not set, while a large number of winning random numbers for the 15-card role are newly established. Accordingly, each RB game is in a gaming state that is advantageous to the player who can win a 15-player combination with a high probability, while there is no possibility that the replay combination or the BB combination will be won internally. In particular, in the slot machine 1 of this example, as shown in FIG. 5, a different winning random number table is set for each RB game. In the first and third RB games, the winning combination of the plum can be won internally, while in the second RB game, the winning random number of the winning combination of the plum is not set, so there is no possibility of winning an internal winning.

  As shown in FIG. 6, the winning random number table for lottery of RB games is a data table in which winning random numbers for determining each RB game by lottery in the BB game are defined. As shown in the figure, during the occurrence of the first BB game in the first special state, the first and second RB games are determined with a half probability, and there is no possibility that the third RB game is determined. On the other hand, in the second BB game in the second special state, the first RB game and the third RB game can be determined with a probability of 1/4, and the second RB game can be determined with a probability of 1/2.

  As shown in FIG. 1, the random number extraction unit 35 is a part that extracts a random number for internal lottery. The random number extraction unit 35 extracts a random number from the integers generated by the random number generation unit 350. The random number generator 350 can generate an integer belonging to a range of 0 to 65535 (decimal number display) and a random number belonging to a range of 0 to 127 (decimal number display). The random number extraction unit 35 samples an integer generated by the random number generation unit 350 using a game start signal corresponding to the operation of the start lever 62 as a trigger (trigger), and extracts it as a random number for internal lottery. The random number extracted by the random number extraction unit 35 is a random number for internal lottery (0 to 65535) for the internal lottery means 42 to draw the internal winning combination, or an internal lottery for the specific state lottery means 46 to draw the RB game. Random number (0-127).

  As shown in FIG. 1, the internal lottery means 42 is a means for determining an internal winning combination by lottery and establishing a corresponding internal winning flag. The internal lottery means 42 draws an internal winning combination using random numbers belonging to the range of 0 to 65535 extracted by the random number extraction unit 35. As shown in FIG. 3, the internal winning combination that the internal lottery means 42 of the present example draws includes seven types of BIG bonus combination, plum role, bell role, watermelon role, cherry role, replay role, There are 15 winning combinations that can only be won during an RB game.

  The winning flag control means 41 is a means for controlling an internal winning flag representing a state in which each winning combination can be won. The winning flag control means 41 is in an off state with respect to an internal winning flag such as a small role including a replay role before starting the next game regardless of whether or not a winning is made in a game in which the internal winning flag is set for the first time. Switch to. On the other hand, the BIG bonus flag (referred to as the BB flag as appropriate), which is an internal winning flag for the BB combination, is carried over to the next game until winning, and switched to the off state in accordance with the winning of the BB combination. By such control, a small combination including a replay combination that was not won in the internal winning game becomes so-called missing. On the other hand, once the BB combination is won internally, the bonus confirmed state can be maintained until winning.

  As shown in FIGS. 1 and 2, the display control means 45 is a means for starting the symbol fluctuation of the reel 21 according to the fluctuation start signal and stopping the symbol fluctuation of the reel 21 according to the fluctuation stop signal. . The display control means 45 inputs a control pulse to the stepping motor constituting the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control unit 45 counts the number of control pulses input to the reel driving unit 22, that is, the number of steps rotated by the stepping motor. In particular, the display control means 45 of this example counts the number of steps generated after the most recent detection signal by resetting the number of steps to zero each time the detection signal of the reference position piece of each reel 21 is fetched.

  As shown in FIG. 1, the display control means 45 performs so-called pull-in control for stopping symbols within a predetermined pull-in range determined by rules (rules for game machine certification, type verification, etc.) on the winning line. . In this example, a range corresponding to 4 symbols is set as the pull-in range. The display control means 45 calculates the bita symbol, which is the symbol 20 instantaneously located on the winning line 212, based on the number of steps when the fluctuation stop signal is taken. Furthermore, a symbol to be stopped is determined from the total of five symbols of the four symbols belonging to the bita symbol and the drawing range. The display control means 45 pulls the symbol determined (to be stopped) as described above and stops the reel 21.

  As shown in FIGS. 1 and 2, the winning determination means 49 is a means for determining whether or not a combination of symbols that the three reels 21L, 21C, 21R stop display is a winning symbol. Specifically, the winning determination means 49 determines whether or not the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R is a winning symbol. And determine the winning combination. The winning determination means 49 takes in the number of steps of each stepping motor constituting the reel drive unit 22 after each reel 21L, C, R stops. The winning determination means 49 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20.

  As shown in FIG. 1 and FIG. 3, the profit granting means 40 is a means for giving a profit according to the winning combination determined by the winning determination means 49. For example, when the BB combination is a winning combination, a profit that a BB game is generated is given. Further, when the watermelon role is a winning combination, a benefit of paying out 5 medals is given.

  As shown in FIGS. 1 and 6, the special state generating unit 43 is a unit that generates a BB game in response to winning of the BB combination. As the special state generated by the slot machine 1 of this example, there are two types, that is, a first BB game (first special state) and a second BB game (second special state) having different lottery probabilities for each RB game. In the special state generating means 43, a BB game flag that is a control flag of the BB game is defined. The special state generating means 43 sets the first (second) BB game flag to the on state in response to the winning of the first (second) BB role, while the total number of payouts reaches 465 The 1 (second) BB game flag is reset to the off state.

  As shown in FIG. 1, the remaining payout counting means 431 is a means for counting the remaining payout number of medals until the BB game is finished (remaining payout number). In the remaining payout number counting means 431, a remaining payout number counter for counting the remaining payout number is set. The remaining payout number counting means 431 sets an initial value of 465 as a counter value of the remaining payout number in accordance with the occurrence of the BB game, and the counter of the remaining payout number counter every time one medal is paid out during the occurrence of the BB game. Subtract and accumulate values one by one.

  As shown in FIG. 1, the specific state determination unit 44 is a unit that determines whether the game is one of the first to third RB games during the occurrence of the BB game. The specific state determination unit 44 outputs a specific state end signal to the specific state lottery unit 46 when it is determined that none of the first to third RB games is occurring during the occurrence of the BB game.

  As shown in FIGS. 1 and 6, the specific state lottery means 46 is a means for determining, by lottery, an RB game to be generated in the BB game among the first to third RB games. The specific state lottery means 46 of this example executes the RB game lottery upon receiving the specific state end signal. In the RB game lottery, the specific state lottery means 46 checks the random number in the range of 0 to 127 extracted by the random number extraction unit 35 with the winning random number table of FIG. As described above, in the specific state lottery means 46 of this example, one of the first to third RB games is determined by lottery.

  The specific state generating means 48 is a means for generating an RB game determined by the specific state lottery means 46 by lottery. The specific state generating means 48 defines first to third RB game flags that are control flags for the first to third RB games. The specific state generating means 48 generates an RB game corresponding to the on-state RB game flag among the first to third RB game flags.

  The specific state generating means 48 defines a winning counter for counting the number of winnings during the generation of the RB game and a game counter for counting the number of digested games. The specific state generating means 48 sets initial values to the winning counter and the game counter when the RB game flag is flagged up. Then, every time a winning game occurs, the counter value of the winning counter is subtracted and integrated, and every time the game is consumed, the counter value of the game counter is subtracted and integrated. The specific state generating means 48 resets the RB game flag to an off state when the winning counter or the game counter reaches zero.

  Note that the specific state end condition, which is the end condition of the RB game, differs depending on the type of the RB game. As for the first and third RB games, the specific condition end condition is that any one of the four winnings as the prescribed number of winnings, the digestion of the six games as the prescribed number of games, and the end of the BB game is satisfied. Is set. For the second RB game, it is set as a specific state end condition that any one of the eight winnings as the prescribed number of winnings, the digestion of the 12 games as the prescribed number of games, and the end of the BB game is satisfied. Yes. In the specific state generating means 48, when the first and third RB games are started, four times or six games are set as initial values of the winning counter and the game counter. In addition, when the second RB game is started, 8 times or 12 games are set as initial values of the winning counter and the game counter.

  The RT generation means 47 is means for generating a replay time. The replay time generated by the slot machine 1 of this example includes a first replay time and a second replay time that have different RT end conditions. The RT end condition for the first replay time is that the number of digested games has reached 100 games. The RT termination condition for the second replay time is that the number of digested games has reached 50 games. The RT generation means 47 defines an RT flag that is a replay time control flag. The RT generating means 47 generates a replay time according to the on-state RT flag. Further, the RT generating means 47 includes an RT counter 471 for counting the number of games digested in the replay time. The RT counter 471 is a counter that subtracts and integrates the number of games started from the initial value and digested in the replay time.

  The RT generator 47 sets the RT flag to the on state in response to the end of the first RB game or the second RB game. On the other hand, when the counter value of the RT counter 471 reaches zero, the RT flag is reset to the off state. The RT generating means 47 sets 100 games as the initial value of the RT counter 471 for the first replay time, and sets 50 games as the initial value of the RT counter 471 for the second replay time. The RT flag is forcibly reset to the off state when the first to third RB game flags are set to the on state.

  In this example, the RT end condition is made different between the first replay time and the second replay time. Instead, the internal winning probability of the replay combination may be made different. Furthermore, both the RT end condition and the internal winning probability of the replay combination may be different between the first replay time and the second replay time. As in this example, the internal winning probability of the replay role is made the same, but if only the RT end condition is made different, the player is given a sense of tension that the replay time that occurs after the end of the BB game will not be known. Can do.

  Next, the operation of the slot machine 1 of this example configured as described above will be described with reference to the flowcharts of FIGS. FIG. 7 is a flowchart showing the flow of the game start process in the slot machine 1 of this example. FIG. 8 is a flowchart showing the flow of the winning process in the slot machine 1 of this example.

  First, the flow of the game start process will be described with reference to FIG. In the game start process, first, in step S101, it is determined whether or not a game start operation is detected. If a game start operation is detected, the flag state of the BB game flag is determined in step S102.

  When the flag value of the BB game flag is 1 (on state), that is, when the BB game is being generated, the flag state of each RB game flag is determined as in step S110. When the flag values of all the RB game flags are zero (off state), one type of RB game is determined by lottery using the winning random number table shown in FIG. 6 as in step S111. In step S112, 1 (ON state) is set to the RB game flag corresponding to the RB game determined by the lottery.

  Thereafter, the process proceeds to step S103, where an internal winning combination is drawn. In subsequent step S104, the counter value of the RT counter 471 is decremented by one game. In step S105, it is determined whether or not the RT counter 471 has reached zero. If the RT counter 471 is not zero, the flag states of the first to third RB game flags are determined (step S120). If the RT counter 471 is zero (step S105), or if any RB game flag is 1 (on state) (step S120), the RT flag is reset to zero (off state) as in step S106. The Thereafter, the rotation of the reel 21 is started as in step S107.

  Next, the flow of the winning process will be described with reference to FIG. In the winning process, it is first determined whether or not a stop operation of the left reel 21L has been detected in step S201. When the stop operation of the left reel 21L is detected, the left reel 21L is stopped as in step S202. In step S220, it is determined whether or not a stop operation of the middle reel 21C has been detected. When the stop operation of the middle reel 21C is detected, the middle reel 21C is stopped as in step S221. In step S230, it is determined whether a stop operation of the right reel 21R has been detected. When the stop operation of the right reel 21R is detected, the middle reel 21C is stopped as in step S231. Then, the above-described processing is repeatedly executed until all the reels 21L, C, and R are stopped as in step S203.

  When all the reels 21 are stopped (step S203), the process proceeds to step S204 to determine whether or not the symbol stopped on the winning line is a winning symbol. When the replay combination is won as in step S205, the replay game is set (step S206), and the replay combination flag that is the internal winning flag of the replay combination is reset (step S207).

  If the replay combination has not been won in step S205, the winning of the first (second) BB combination is determined as in step S240. If the first (second) BB combination is won, the first (second) BB game flag corresponding to the first (second) BB combination won in step S241 is set to 1 (ON state). At the same time, the first (second) BB combination flag is reset as in step S242. In step S243, the RT flag is reset.

  When neither the replay combination nor the first (second) BB combination has been won (steps S205 and S240), the small combination is determined as in step S250. When the small combination has won, a medal payout process P1 corresponding to the type of the small combination won is executed, and then the internal winning flag of the small combination is reset.

  In the subsequent step S208, it is determined whether or not the BB game end condition has been achieved. When the end condition of the BB game is achieved, the first (second) BB game flag is reset to zero (off state) as in step S209. In the subsequent step S210, it is determined whether or not the end condition of the first RB game has been achieved. When the end condition of the first RB game is achieved, the first RB game flag is reset as in step S211 and 100 games are set as the initial value of the RT counter 471 (step S212).

  When the end condition of the second RB game is achieved (step S260), the second RB game flag is reset as in step S261, and 50 games are set as the initial value of the RT counter 471 (step S262). If 100 games or 50 games are set as the initial value of the RT counter 471, then the RT flag is set to 1 (ON state) as in step S213.

  When the end condition of the third RB game is achieved (step S270), the third RB game flag is reset as in step S271. Since the end of the third RB game does not trigger the occurrence of the replay time, step S213 for raising the RT flag to 1 (on state) is bypassed.

  Next, the transition of the gaming state in the slot machine 1 of this example that operates as described above will be described with reference to the time chart of FIG. The figure illustrates a game pattern including the occurrence of the second BB game. It should be noted that the second BB game flag, the first to third RB game flags, and the RT flag are arranged in order from the top in the vertical axis direction in FIG. The horizontal axis in the figure defines time. A flag value 1 in each state flag represents a state in which a corresponding gaming state can occur.

  In the game pattern shown in FIG. 9, according to the start of the second BB game, first, the first RB game, the second RB game, and the third RB game are generated in this order, and then the second RB game is generated three times in succession. Thereafter, the pattern shifts from the first RB game to the second RB game and the second BB game ends. As shown in the figure, in the second BB game, one of the first to third RB games is repeatedly generated. Although the RT flag corresponding to the replay time is flagged up at the end of each RB game, it is reset according to the flag up of the RB game flag corresponding to the new RB game. Therefore, during the occurrence of the second BB game, even if the RT flag is flagged up, the replay time does not actually occur. Thereafter, when the second RB game is ended in accordance with the end of the second BB game, the RB game flag corresponding to the new RB game is not flagged up. Therefore, the flag flag up state of the RT flag is maintained, and the replay time actually occurs. Here, since the second RB game has occurred lastly, the second replay time over 50 games can occur as described above.

  As described above, in the slot machine 1 of this example, whether or not a replay time occurs or the type of replay time differs depending on the type of RB game that occurred at the end of the BB game. Therefore, according to this slot machine 1, it is possible to maintain a high level of interest in games during the occurrence of a special BB game.

  In particular, in the BB game in which the slot machine 1 of this example is generated, the type of the RB game is determined by lottery, so that it is difficult for the player to make a determination. Therefore, in the game of the slot machine 1, it is possible to enjoy the prediction of the type of replay time that can occur following the BB game by predicting the type of RB game that occurs in the BB game.

  In this example, depending on the type of RB game at the end of the BB game, the number of replay time continuation games is different from 100 games, 50 games, and zero games (the case where no replay time is generated). Instead, any one of a plurality of types of replay times having different internal winning probabilities for any of the combinations may be selectively generated according to the type of the RB game.

In this example, two types of BB combination are set, but there may be one type of BB combination or three or more types.
About the kind of RB game, it may replace with three types of this example, and may set two types or four or more types. The specific state end condition, which is the end condition of the RB game, is not limited to the specified number of games and the specified number of winnings in this example, and other conditions can also be set.

  In addition, in this example, it is set that the number of digested games has reached the specified number of games as an RT end condition that is a replay time end condition. Instead of this, a stop display of a predetermined symbol is displayed as the RT end. It may be set as a condition. Furthermore, it is also possible to provide a level difference in the internal winning probability of the replay role depending on the type of replay time. Further, when a plurality of types of replay combinations having different winning symbols are set, it is only necessary that the internal winning probability of at least one of the replay combinations is different between the normal state and the replay time.

(Example 2)
This example is an example in which a notification function for assisting prediction of an RB game is added based on the slot machine of the first embodiment.
In the slot machine of this example, specific state notification means for notifying specific state information indicating the type of the RB game that is occurring in the BB game is added. Furthermore, the specific state lottery means of this example is configured to execute a lottery for determining whether or not to notify the specific state information every time an RB game is determined by lottery.

The specific state lottery means (reference numeral 46 in FIG. 1) uses a random number for RB game lottery to determine whether or not to notify the specific state information by lottery.
When the specific state lottery determines notification, the specific state notification means notifies the specific state information at the start of the corresponding RB game. The specific state information includes information indicating the type of the RB game. The specific state notification unit of this example displays image information that can specify the type of the RB game on the display screen of the liquid crystal display unit (reference numeral 530 in FIG. 1). The specific state notification means notifies any one of sound effects, display by the liquid crystal display unit, production by a notification lamp or the like, or a combination thereof.
Other configurations and operational effects are the same as those in the first embodiment.

In this example, the start time of the corresponding RB game is set as the timing at which the specific state notification unit notifies the specific state information. Instead, the notification timing may be set in the middle or at the end of the RB game, or a random notification timing may be set.
Furthermore, it is also preferable to change the production method or the like by the specific state notification means according to the type of the RB game corresponding to the specific state information.

(Example 3)
This example is an example in which a notification function for notifying RT information, which is information suggesting a replay time, is added based on the slot machine of the first embodiment.
In the slot machine of this example, RT notification means for reporting RT information indicating whether or not to generate a replay time after the end of the BB game and the type of the replay time to be generated is added. Further, in the slot machine of this example, a fourth RB game in a specific state is newly established in which a minimum payout number of 20 medals paid out in a specific state is guaranteed in order to establish a specific state end condition. . A replay time of 80 games is set for the fourth RB game.

When the fourth RB game is generated, the RT notification means includes a counter value of a remaining payout number counter (reference numeral 431 in FIG. 1) described in the first embodiment, and a minimum payout number of 20 sheets. Compare When the number of remaining payouts indicated by the counter value of the remaining payout number counter is less than 20, the RT notification means notifies the RT information indicating that the replay time of the 80 games is generated. The RT notification means notifies the RT information by using any one of sound effects, a display by a liquid crystal display unit (reference numeral 530 in FIG. 1), an effect by a notification lamp or the like, or a combination thereof.
Other configurations and operational effects are the same as those in the first embodiment.

  Of the first replay time, the second replay time, and the replay time of the 80 games in this example, the replay time that is most advantageous to the player is the first replay time over 100 games. When it is determined that the first replay time is generated subsequent to the BB game, the RT notification means may be configured to notify the player of that fact. Furthermore, the production method or the like may be changed according to the type of replay time corresponding to the RT information.

Example 4
In this example, based on the slot machine of the first embodiment, an effect unit for executing an effect as a hint when predicting an RB game is added.
The effect means (not shown) in this example is a means for selectively executing one of a plurality of kinds of effects during the generation of the RB game. This effect means, during the occurrence of the second and subsequent RB games in the BB game, the effect selected from the plurality of types of effects according to the combination of the type of the previous RB game and the type of the RB game being generated Execute. The effect means executes the effect every time the second and subsequent RB games in the BB game occur.

Other configurations and operational effects are the same as those in the first embodiment.
In addition, the timing of the production by the production means may be selectively generated by lottery every time the second and subsequent RB games are generated, instead of this example.
