Description

  The present invention relates to a slot machine that generates an advantageous gaming state according to a stop display of a specific symbol.

  Conventionally, for example, a slot machine is known in which an advantageous gaming state such as an RT state occurs in response to a stop display of a specific symbol (see, for example, Patent Document 1). There are various types of specific symbols. For example, a winning symbol or a missing symbol of a specific small role is often set as the specific symbol.

  However, the conventional slot machine has the following problems. In other words, if the number of specific symbols is increased, even beginners who are not good at making it can easily stop displaying specific symbols, but there is a possibility that it will be insufficient for advanced users, while the number of specific symbols However, there is a problem that beginners may feel dissatisfied, although the difficulty level of the increase will be increased and the game will be able to be enjoyed by advanced players.

JP 2008-212207 A

  The present invention has been made in view of the above-described conventional problems, and in a slot machine that generates an advantageous gaming state in response to a stop display of a specific symbol, beginners are not satisfied when the specific symbol is stopped and displayed. It is intended to provide a slot machine with excellent playability that can be enjoyed by advanced players with little fear.

The present invention includes a symbol variation display means for variably displaying a plurality of types of symbols according to a predetermined arrangement in a plurality of symbol display areas,
Game start operation means operated by the player to start the game with the game medium inserted;
Internal lottery means for executing an internal lottery for determining an internal winning combination from a plurality of types of combinations including a first special combination, a second special combination and a specific small combination when the game start operation unit is operated When,
A stop operation means operated by a player to stop the display of the variation of the symbol by the symbol variation display means;
When the stop operation means is operated, a display control means for drawing a symbol corresponding to the internal winning combination within a predetermined pull-in range and stopping and displaying it in the symbol display area;
Winning determination means for determining whether a winning has occurred based on a combination of symbols stopped and displayed in each symbol display area of the symbol variation display means;
Profit granting means for granting a player a profit corresponding to the winning when the winning determining means determines that a winning has occurred;
First CT state generating means for generating a first CT state in which the pull-in range is limited to the first pull-in range in at least the next game according to the winning of the first special combination;
Second CT state generating means for generating a second CT state in which the pull-in range is limited to a second pull-in range narrower than the first pull-in range in at least the next game in response to the winning of the second special combination When,
In the first CT state, when a combination of symbols stopped and displayed in each symbol display area matches a symbol corresponding to the specific small role, a first special game state that generates a first special gaming state advantageous to the player is generated. Gaming state generating means;
In the second CT state, when a combination of symbols stopped and displayed in each symbol display area matches a symbol corresponding to the specific small role, a second special gaming state that is more advantageous than the first special gaming state is obtained. A second special gaming state generating means for generating,
The internal lottery means may determine both the first special combination and the second special combination as internal winning combinations simultaneously in one game,
In the game in which both the first special combination and the second special combination are determined as internal winning combinations at the same time, the display control unit is configured to perform the first operation mode when the operation mode of the stop operation unit is the first operation mode. A symbol corresponding to one special combination is drawn into the symbol display area and stopped. When the operation mode of the stop operation means is the second operation mode, the symbol corresponding to the second special combination is displayed in the symbol display area. The slot machine is configured to be drawn and stopped and displayed (claim 1).

  In the slot machine of the present invention, the first special combination serves as an opportunity for the first CT state, while the second special combination serves as an opportunity for the second CT state. The difference between the first CT state and the second CT state is in the pull-in range when the symbol is stopped. The second pull-in range applied to the second CT state is set to be narrower than the first pull-in range applied to the first CT state. If the pull-in range set in the display control means is narrowed, the difficulty level of winning for the specific small role by so-called eye-catching that stops the target corresponding to the specific small role is increased. Therefore, in the second CT state, the difficulty level of winning the particular small role is higher than that in the first CT state.

  In the slot machine, the degree of advantage of the first special gaming state according to the winning of the specific small role in the first CT state, and the second special gaming state according to the winning of the specific small role in the second CT state The degree of advantage reflects the difference in the difficulty of winning the special small role. That is, the second special game state is more advantageous than the first special game state, reflecting the difficulty of winning the specific small role in the second CT state.

  In the game of the slot machine of the present invention, the first special combination and the second special combination may be simultaneously determined as internal winning combinations (hereinafter referred to as simultaneous winning). When the first special combination and the second special combination are won simultaneously, the first special combination can be won by operating the stop operation means based on the first operation mode, and based on the second operation mode. By operating the stop operation means, the second special combination can be won. That is, in the game of the slot machine, when the first special combination and the second special combination are won simultaneously, the player performs a stop operation based on the first operation mode or based on the second operation mode. Depending on whether the stop operation is performed, the special role to win is switched.

  If it is a beginner or the like, it is preferable to generate the first CT state that is easy to push by winning the first special role. This is because in the first CT state, the specific small role can be won relatively easily, thereby generating the first special game state that is advantageous to the player. On the other hand, it is preferable that a so-called advanced player, etc., win the second special combination and generate the second CT state. This is because, in the second CT state, although it is difficult to push, the second special game state that is more advantageous than the first special game state can be generated if the specific small role can be won.

  As described above, in the slot machine of the present invention, there is little possibility that beginners will feel dissatisfied, and excellent gaming properties that can be fully enjoyed by advanced players are realized.

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, in the first CT state and the second CT state, it is preferable to set the internal winning state of all the small combinations including the specific small combination. Further, the number of continued games in the first CT state and the second CT state may be only one game or a plurality of games.

Further, it is preferable that the internal lottery means determine the specific small combination as an internal winning combination in the first CT state and the second CT state.
In this case, in the first CT state and the second CT state, it is possible to win a prize aiming at the specific small role. If the specific small combination can be won, the first special game state or the second special game state can be generated.

Further, in a game in which both the first special combination and the second special combination are determined as internal winning combinations at the same time, the first operation mode and the second operation mode are notified before the stop operation unit is operated. It is preferable that an operation mode notifying unit for performing the operation is provided.
When notification of the first operation mode and the second operation mode is performed by the operation mode notification unit, the player selects whether to perform the first operation mode or the second operation mode. Thus, the first special combination or the second special combination can be selectively won. If the first special combination or the second special combination can be selectively won, either the first CT state or the second CT state can be selectively generated according to the player's preference.

  The slot machine of the present invention is a slot machine with excellent characteristics that realizes a gameability that can be enjoyed widely from beginners who are not good at pressing to advanced players who are good at pressing.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example relates to a slot machine 1 that generates an SCT state (SCT1 state, SCT2 state) in which a winning range when a symbol is stopped is limited and a winning can be aimed at any role by so-called pressing. . The contents will be described with reference to FIGS.

  First, the external configuration of the slot machine 1 of this example will be described with reference to 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 is configured by arranging a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 on the upper side of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed below the symbol display window 11. On the right side of the symbol display window 11, a payout number display portion 551 for displaying the payout number of medals (game media) and a credit display portion 552 for displaying the credit amount are arranged.

  The base portion 100 is formed so as to protrude relatively with respect to the symbol display window 11 located behind the player. 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 for paying out medals at the lower end, and between the operation surface 14 and the medal tray 15. An operation panel 13 is provided.

  On the operation surface 14, a bet button 64 for inserting a medal credited (stored) by a credit function, a settlement button 65 for paying out a credited medal, and a medal insertion for directly inserting a medal A mouth 630 is arranged. The operation panel 13 is provided with a start lever 62 (game start operation means) for starting the symbol fluctuation of the reel 21 and a stop button 61 (stop operation means) for stopping the symbol fluctuation.

  The bet button 64 is a button for inserting a predetermined number of medals out of credited medals. In a non-bonus state in which a three-bet game is set, a 3-bet signal indicating the number of insertions 3 is generated in accordance with the operation of the bet button 64. On the other hand, in a bonus state in which a two-bet game is set, a 2-bet signal is generated in response to the operation of the bet button 64. However, if the remaining credit is insufficient, a 1 bet signal or the like is generated, and if the credit is zero, no bet signal is generated.

  The start lever 62 is an operation lever that generates a game start signal that is a control signal for the reel 21 in accordance with the player's operation. In the slot machine 1, the start lever 62 is set to the valid state on the premise that a medal is inserted directly or a medal is inserted by operating the bet button 64. When the replay winning combination is won, a state is set in which a medal is directly inserted or a medal is automatically inserted without a betting operation, that is, a state where the next game can be started.

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

  As shown in FIG. 2, the winning line in this example includes a middle horizontal winning line 211, diagonal winning lines 212 and 213, a V-shaped winning line 214, and an inverted V-shaped winning line 215. It consists of five irregular lines. In the symbol display areas 110L and R on both sides, all three symbols in the upper middle stage and lower stage correspond to symbols on any winning line, while in the central symbol display area 110C, only one symbol in the middle stage corresponds to symbols on the winning line. .

  Reels 21L, C, and R constituting the symbol variation display means 2 are arranged on the back side of the symbol display areas 110L, C, and R, respectively. As will be described in detail with reference to FIG. 4, the reels 21L, C, and R are rotary reels having a cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof at substantially constant intervals. . 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.

  As shown in FIG. 1, the stop button 61 is an operation button that generates a fluctuation stop signal that is a control signal for the reel 21 in accordance with the player's operation. 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.

The speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light.
The payout number display unit 551 is a display unit that displays the number of medals paid out at the time of winning a prize.
The credit display unit 552 is a display unit that displays the number of medals credited (stored) by the credit function.

  The liquid crystal display unit 53 includes a liquid crystal display. The liquid crystal display unit 53 can display various effect screens including a simultaneous winning notification screen 710, an SCT screen 720, and RT screens 730 and 740. The contents of the simultaneous winning notification screen 710, the SCT screen 720, and the RT screens 730 and 740 by the notification means 71 or the operation mode notification means 72 will be described in detail later with reference to FIGS.

Next, the role of the slot machine 1 of this example, the symbol arrangement on each reel 21, and the outline of game play will be described.
In the slot machine 1 of this example, as shown in FIG. 3, bonus combinations (BIG, REG), 10-sheet combinations A to D, SCT1 combination (first special combination), SCT2 combination (second special combination), specific small combination A plurality of types of small roles including a single combination and a replay combination are set. In FIG. 3, the name of each combination is shown in the left column, a winning symbol that is a combination of symbols 20 corresponding to each combination is shown in the middle column, and the profit given to the player according to the winning is shown in the right column.

  Here, the winning symbols of the 10-piece roles A to D will be described. “Black orange” and “white orange” are set in the reels 21L, C, and R as the winning symbols constituting the winning symbol of the 10-sheet winning A. There are 8 types of winning symbols for 10 combinations A, which are all combinations of 2 types of “orange”. In this example, eight types of 10-piece combinations A corresponding to these eight types of winning symbols are always won internally.

  The winning symbol constituting the winning symbol of 10 winning combinations B to D is the symbol “R” at any one specific reel, and any of the two types of symbols “orange” at the other reels. . For example, as the winning symbols for the 10-piece combination B, four types of combinations of two types of “orange” in the right reel 21R and the middle reel 21C are combined with the symbol “R” of the left reel 21L. Winning design is set. Note that the 10-piece combination B that can be won internally in one game is any one of the four 10-type combinations B corresponding to the four types of winning symbols. Similarly, there are four types of winning symbols for the 10-piece combination C (D), and any one of these four types of 10-piece combinations C (D) can be individually won internally.

In each reel 21L, C, R, symbols are arranged as shown in FIG.
In the left reel 21L and the right reel 21R, the maximum interval for a specific type of symbol “orange” is 13 symbols or more, and the maximum interval for any type is 6 symbols. Here, in the slot machine 1 of this example, as described later, a range corresponding to four symbols is set as a normal pull-in range when the reel 21 stops. Further, as described above, in the symbol display areas 110L and R, a winning line is set over three symbols in the upper middle stage and the lower stage. Therefore, in the non-SCT state, one of the two types of “orange” in the left reel 21L and the right reel 21R is always within the pull-in range regardless of the timing of the stop operation. On the other hand, certain types of “orange” may not be within the pull-in range depending on the timing of the stop operation. In order to stop and display a specific type of “orange” on the left reel 21L and the right reel 21R, it is necessary to operate the corresponding stop buttons 61L and 61R in a timely manner even in the non-SCT state.

  For the two types of “orange” in the middle reel 21C, the maximum interval for any type is 4 symbols, and the maximum interval for a specific type of symbol “orange” is 13 symbols or more. Therefore, in the non-SCT state, the “orange” in the middle reel 21C does not need to be pressed unless the type is asked, whereas the specific type of “orange” is a pattern that needs to be pressed. Yes.

  From the above, if the 10-piece combination A in the slot machine 1 of the present example is in the non-SCT state, all the reels 21 have a combination in which the combination symbols are arranged at intervals that can be drawn on the winning line. Yes. The 10-piece roles B, C, and D are roles in which role symbols are arranged at intervals that can be always drawn on the winning line only in the left reel 21L, the middle reel 21C, and the right reel 21R.

  Next, the outline of the playability of the slot machine 1 of this example will be described. The gaming state generated by the slot machine 1 includes a non-RT state, an RT state, and a bonus state. In the non-RT state, in addition to the normal state, the pull-in range is limited, while an SCT state in which a winning can be obtained by aiming is generated. In the RT state, AT may be activated. When the AT is activated, when 10 winning combinations are won at the same time, the stop order for winning 10 winning combinations A that do not need to be pressed is notified. The game state transition will be described in detail later with reference to FIG.

  Next, the electrical configuration of the slot machine 1 of this example will be described with reference to FIG. For the control unit 3 that controls the overall operation of the slot machine 1, in addition to the above-described configuration, the inserted medal detection unit 63 that detects a medal inserted directly through the medal slot 630 (FIG. 1), the reel 21 A reel driving unit 22 constituting the symbol variation display means 2, a reference position detecting unit 66 for detecting the rotational position of the reel 21, a medal paying unit 54 for paying out medals, a payout number display unit 551 and a credit number display unit 552 are included. Various display units 55, a set value operation unit 68 for setting a set value representing the player's degree of advantage, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 is a detection unit for a medal inserted directly 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 unit 630. In the slot machine 1 of this example, when a predetermined number of medals are inserted by direct insertion of medals or operation of the bet button 64, the start lever 62 is set to an effective state and a new game can be started. It becomes a state.

The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is means for rotating the reel 21 by the rotational driving force of the stepping motor.
The reference position detection unit 66 is a detection unit that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.

The medal payout unit 54 is a payout unit that pays out a predetermined number (see FIG. 3) of medals in accordance with winning.
The set value operation unit 68 is an operation unit for changing the set values 1 to 6 having different internal winning probabilities such as bonus combinations using the setting key 680.

  As shown in FIG. 5, the control unit 3 includes a CPU 31, ROM 33 and RAM 34 as memory means, an I / O unit 32 as an input / output interface, a random number extraction unit 35 that extracts a random number for internal lottery, a random number And a random number generator 350 for generating. The CPU 31 executes a software program read from the ROM 33, thereby executing an internal lottery means 41 for lottering an internal winning combination, a flag control means 410 for controlling an internal winning flag corresponding to the internal winning combination, and a display control for controlling the reel 21. Means 42, winning determination means 43 for determining a winning symbol, profit granting means 44 for giving a profit corresponding to the winning, first CT state generating means 451 for generating an SCT1 state (first CT state) in response to winning of the SCT1 role, Second CT state generating means 452 for generating an SCT2 state (second CT state) according to the winning of the SCT2 role, and the RT state (first special gaming state) according to the winning of one single role (specific small role) in the SCT1 state The first special gaming state generating means 461 to be generated, the RT state (the first state) according to the winning of a single combination in the SCT2 state A second special gaming state generating means 462 for generating a special gaming state), an AT lottery means 47 for executing an AT activation lottery for determining whether or not to activate an AT, an AT high-accuracy state having different expectations for the AT, and Each function is realized as a state setting unit 481 that selectively sets one of the AT low-accuracy states, and a transition lottery unit 482 that executes a transition lottery between the AT high-accuracy state and the AT low-accuracy state.

  The ROM 33, which is a memory means, has an internal winning combination lottery table (FIG. 6) used by the internal lottery means 41 for the internal winning combination lottery, and a transition lottery table (used for the transition lottery between the AT high-accuracy state and the AT low-accuracy state). The AT activation lottery table (FIG. 7) used for the AT activation lottery and the reel control table (not shown) used by the display control means 42 for the stop control of the reel 21 are stored.

  As shown in FIG. 6, the internal winning combination lottery table is a data table in which winning random numbers for each combination are defined from among random numbers for lottery of 0 to 65535. The internal winning combination lottery table includes a table applied to the normal state, a table applied to the RT state, a table applied to the SCT state (SCT1 state, SCT2 state), and a table applied to a bonus state (not shown). There is. An internal winning combination lottery table for each gaming state excluding the bonus state is prepared for each set value of 1-6. In the figure, among the columns corresponding to each gaming state, the left column in the vertical direction indicates the number of winning random numbers, and the right column indicates the internal winning probability by the denominator (x of 1 / x).

In the table for the normal state, as the winning random numbers for the SCT1 role and the SCT2 role, only simultaneous winning random numbers that are simultaneously determined as internal winning roles are defined. Therefore, one of the SCT1 role and the SCT2 role is not internally won by itself, and the internal winning is always performed at the same time.
In the RT state table, most of the lost random numbers in the normal state table are defined as winning random numbers for the replay role. Therefore, in the RT state, the internal winning probability of the replay combination is 1 / 1.5, which is much higher than the normal state that is 1 / 7.3.
In the table for the SCT state, the winning random number for the bonus combination is not stipulated, and the possibility that the bonus combination is won internally is zero. On the other hand, in the SCT state, regardless of the internal lottery, all the small combinations including the single combination which is a specific small combination are in an internal winning state. The winning random number for the replay role is common to the table for the normal state.

  The transfer lottery table (not shown) is a data table in which winning random numbers for the transfer lottery between the AT high-accuracy state and the AT low-accuracy state are defined. In this example, a part of the winning random number for the replay combination under the normal state is set as the winning random number for the transfer lottery. Of the 8980 winning random numbers (see FIG. 6) for the replay role, 1000 are the winning winning random numbers from the AT low-accuracy state to the AT high-accuracy state, and 2000 are the AT high-accuracy state to the AT low-accuracy state. It is a random number elected to transition to the state.

  A reel control table (not shown) is a data table in which a stop position that can be stopped on the winning line is defined. As the reel control table, in addition to the SCT1 state table and the SCT2 state table, a non-SCT state table is set. The reel control table for the non-SCT state is a table in which a pull-in range corresponding to four symbols is set for all the reels 21. In the table for the SCT1 state, the drawing range corresponding to four symbols is set for the left and right reels 21L and 21R, while the drawing range is limited to one symbol for the middle reel 21C. In the SCT2 state table, the pull-in range is set to zero for all the reels 21.

  The AT activation lottery table is a data table in which winning random numbers for the AT activation lottery are defined as shown in FIG. In the AT activation lottery table, a part of the simultaneous winning random numbers of the SCT1 combination and the SCT2 combination under the normal state are defined as the winning random numbers for the AT activation lottery. In this example, the AT activation lottery is executed when the SCT1 role or the SCT2 role is won. If the AT activation lottery is won, the AT is activated in response to the subsequent transition to the RT state. On the other hand, even if the AT activation lottery is won, the winning is invalid if the state does not shift to the RT state.

  The number of winning random numbers varies depending on whether one of the SCT1 combination and SCT2 combination wins, the AT high-accuracy state, or the AT low-accuracy state. For example, the winning probability of the AT activation lottery when winning the SCT1 role in the AT low-accuracy state is 50/500, while the winning probability of the AT starting lottery when winning the SCT1 role in the AT high-accuracy state is 300/500. In addition, the winning probability of the AT activation lottery when winning the SCT2 role in the AT low-accuracy state is 100/500, while the winning probability of the AT starting lottery when winning the SCT2 role in the AT high-accuracy state is 400/500. As described above, the expectation for AT is higher in the AT high-accuracy state than in the AT low-probability state, and the expectation for the AT is higher in the SCT2 winning prize than in the SCT1 winning prize.

The random number generator 350 is a part for generating random numbers belonging to a predetermined integer range as shown in FIG. The random number generated by the random number generation unit 350 is a random number for internal winning combination lottery belonging to a range of 0 to 65535 for lottering an internal winning combination. In this example, an AT activation lottery, a transfer lottery, etc. are executed using a random number for internal winning combination lottery. Instead of this example, a dedicated lottery random number may be set for each lottery.
The random number extraction unit 35 is a part for extracting random numbers for lottery. The random number extraction unit 35 extracts random numbers for lottery from the random numbers generated by the random number generation unit 350. The random number extraction unit 35 extracts a random number for internal winning combination lottery triggered by a game start signal corresponding to the operation of the start lever 62.

  The internal lottery means 41 is a means for determining an internal winning combination by internal lottery and establishing an internal winning flag corresponding to the internal winning combination. The internal lottery means 41 collates the winning random numbers for each winning set in the internal winning combination lottery table (FIG. 6) with the random numbers for the internal winning combination lottery to determine the internal winning combination. The internal lottery means 41 selectively uses any of the internal winning combination lottery tables according to the gaming state.

  The flag control means 410 is a means for controlling an internal winning flag corresponding to the internal winning combination determined by the internal lottery means 41. The flag control means 410 is in an off state (zero) until the next game is started, regardless of whether or not the internal winning flag of a combination other than the bonus winning combination is won in the game in which the internal winning flag is established for the first time. Reset to). Therefore, if each combination other than the bonus combination is not won in the internal winning game, all will be missed. On the other hand, regarding the bonus combination flag which is an internal winning flag of the bonus combination, the established state of the internal winning flag is sequentially carried over to the next game until winning, and is reset to the off state according to the winning.

  The transfer lottery means 482 is a means for executing a transfer lottery between the AT high-accuracy state and the AT low-accuracy state. The transfer lottery means 482 executes the transfer lottery by comparing the winning random number with the transfer lottery table when the replay combination is won internally in the normal state.

  The AT lottery means 47 is means for executing an AT activation lottery. The AT lottery means 47 collates the random numbers for the internal winning combination lottery extracted in the game in which the SCT1 combination or the SCT2 combination wins, that is, the simultaneous selection random numbers of the SCT1 combination and the SCT2 combination with the AT activation lottery table (see FIG. 7). As a result, the AT activation lottery is executed. If this AT activation lottery is won, the AT will be activated when shifting to the RT state in accordance with the winning of a single winning combination in the SCT state. On the other hand, even if the AT activation lottery is won, the winning is invalid if the state does not shift to the RT state.

  As shown in FIG. 5, the display control means 42 is a means for starting the symbol fluctuation of the reel 21 in response to the game start signal and stopping the symbol fluctuation of the reel 21 in response to the fluctuation stop signal. The display control means 42 inputs a control pulse to the stepping motor that constitutes the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control means 42 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 42 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.

  The display control means 42 performs so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine authorization and type verification, etc.) are stopped on the winning line. In this example, a range corresponding to 4 symbols is set as the maximum drawing range. The display control means 42 determines the stop position by collating the number of steps when the variable stop signal is taken into the reel control table in which the stop position that can be stopped on the winning line is defined. The display control means 42 pulls the symbol corresponding to the internal winning flag to the determined stop position and stops the reel 21.

  The display control means 42 of this example changes the reel control table to be applied depending on whether it is in the non-SCT state, the SCT1 state, or the SCT2 state. When the reel control table for the non-SCT state is used, a pull-in range corresponding to 4 symbols is set for all reels 21. When the SCT1 state table is used, the drawing range corresponding to four symbols is set for the left and right reels 21L and 21R, while the drawing range is limited to one symbol for the middle reel 21C. On the other hand, when the SCT2 state table is used, the pull-in range for all the reels 21 is limited to zero.

  Furthermore, the display control means 42 of this example performs the following pull-in control in the simultaneous winning state of the SCT1 combination and the SCT2 combination. That is, if the left reel 21L is the first stop reel (first operation mode) in the simultaneous winning state, the winning symbol of the SCT1 role is stopped and displayed. On the other hand, if the right reel 21R is the first stop reel (second operation mode), the winning symbol of the SCT2 role is stopped and displayed.

  The winning determination means 43 is a means for determining whether or not the combination of symbols stopped and displayed by the three reels 21L, 21C, 21R is a predetermined winning symbol. Specifically, the winning determination means 43 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 43 takes in the number of steps of each corresponding stepping motor (reel drive unit 22) after each reel 21L, C, R stops. The winning determination means 43 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.

  The profit granting means 44 is a means for giving a profit according to the winning combination determined by the winning determination means 43. For example, in the case where the 10 winning combination is a winning combination, a profit of paying out 10 medals is given. Further, when the SCT1 combination is a winning combination, a benefit of occurrence of the SCT1 state is given. When a single combination which is a specific small combination is a winning combination, a benefit of occurrence of RT state is given in addition to the payout of one medal.

  The first CT state generating means 451 is a means for generating the SCT1 state (first CT state) in response to winning of the SCT1 combination (first special combination). In the SCT1 state, only one game is executed, and returns to the non-SCT state upon completion. The SCT1 state is a state in which the display control means 42 executes the symbol stop control using the reel control table for the SCT1 state as described above. In this SCT1 state, the pull-in range of only the middle reel 21C is limited to one symbol, and the pull-in ranges of the other reels 21L and R remain four symbols.

  The second CT state generating means 452 is a means for generating the SCT2 state (second CT state) in response to winning of the SCT2 combination (second special combination). In the SCT2 state, only one game is executed, and returns to the non-SCT state upon completion. The SCT2 state is a state in which the display control means 42 executes the symbol stop control using the reel control table for the SCT2 state as described above. In this SCT2 state, the pull-in range for all the reels 21 is limited to zero.

  The first special game state generating means 461 is a means for generating an RT state (first special game state) in response to winning of a single combination (special small combination) under the SCT1 state. The RT state ends when 50 games are consumed or a bonus combination is won. The first special game state generation means 461 generates an RT state and activates the AT when the AT activation lottery at the time of winning the SCT1 role is won. If the AT is activated, the first stop reel, which is a procedure for winning the 10-piece combination A when the 10-piece combination is simultaneously won, is notified.

  The second special game state generating means 462 is a means for generating an RT state (second special game state) in response to winning of a single combination (specific small combination) under the SCT2 state. The RT state ends when 50 games are consumed or a bonus combination is won. The second special game state generating means 462 generates the RT state and activates the AT when the AT activation lottery at the time of winning the SCT2 role is won. Here, as described above with reference to FIG. 7, the winning random number of the AT activation lottery is more defined and the winning probability is higher when the SCT2 winning prize is compared with the SCT1 winning prize. Therefore, in the RT state by the second special gaming state generation unit 462, the possibility that the AT is activated is higher than that in the RT state by the first special gaming state generation unit 461, and the degree of advantage is high.

  The state setting means 481 is a means for executing switching setting from the AT high-accuracy state to the AT low-accuracy state or from the AT low-accuracy state to the AT high-accuracy state according to the result of the transfer lottery by the transition lottery means 482. In the AT high-accuracy state, when the shift to the AT low-accuracy state is won, the AT low-accuracy state is set instead of the AT high-accuracy state. In the AT low-accuracy state, when the transition to the AT high-accuracy state is won, the AT high-accuracy state is set instead of the AT low-accuracy state.

  The notification means 71 is a means for executing a notification effect for supporting the player. In the RT state during AT activation, the notifying means 71 executes a notification effect for winning a 10-piece combination A that does not require pressing and can be surely won when a 10-piece combination is won simultaneously. Specifically, the stop order (first stop reel) for winning the 10-piece combination A is notified. In addition, when the AT activation lottery is won, the notification means 71 executes a notification effect that the player can shift to the RT state with AT if one winning combination which is a specific small combination is won.

  The operation mode notifying unit 72 is a unit that notifies the stop order (first operation mode) for winning the SCT1 combination and the stop order (second operation mode) for winning the SCT2 combination. The operation mode notifying means 72 notifies the stop order when the SCT1 combination and the SCT2 combination are won simultaneously. As described above, the stop order for winning the SCT1 combination is that the left reel 21L is the first stop reel. Further, the stop order for winning the SCT2 combination is that the right reel 21R is the first stop reel.

Here, with reference to FIG. 8, description will be made regarding the allocation of winning combinations according to the first stop reel when 10 winning combinations are simultaneously won.
In the slot machine 1 of this example, as described above, in the gaming state excluding the bonus state, there is a possibility that any two types of 10-card combinations B to D and 10-card combination A will be won simultaneously. is there. As shown in the “Combination” column in the figure, the 10 winning combination pattern is a pattern in which 10 winning combinations A, B, and C are simultaneously winning, a 10 winning combination A, B, and D are simultaneously winning, and There is a pattern in which 10-player A / C / D wins simultaneously.

  As described above, for the 10-piece combination B, C, and D, the left reel 21L, the middle reel 21C, and the right reel 21R are specific reels corresponding to “R” that does not need to be pushed. Therefore, as shown in the “first stop allocation” column in the figure, the 10 winning combinations remaining with the possibility of winning are distributed according to the reel 21 that has been stopped first. For example, in the case where a 10-piece combination A, B, and C are simultaneously won, and the first stop reel is the left reel 21L, the combination of the 10-piece combination B stops on the winning line. When the first stop reel is the middle reel 21C, the 10-piece C combination symbol stops on the winning line. When the first stop reel is the right reel 21R, the 10-spot combination A symbol stops on the winning line.

Next, the simultaneous winning notification screen 710 displayed by the operation mode notification unit 72, the SCT screen 720, the RT screen 730, and the RT screen 740 displayed by the notification unit 71 will be described with reference to FIGS.
A simultaneous winning notification screen 710 shown in FIG. 9 is a screen for notifying simultaneous winning of the SCT1 combination and the SCT2 combination in the normal state. The simultaneous winning notification screen 710 is displayed according to the simultaneous winning. The simultaneous winning notification screen 710 includes a state notification column 711 for notifying that it is a chance to shift to the SCT1 state or the SCT2 state, a first operation mode notification column 712 for notifying the stop order for winning the SCT1 combination, and SCT2 A second operation mode notification column 713 for notifying the stop order for winning a winning combination. For example, the first operation mode notification column 711 indicates that the SCT1 combination can be won by stopping from the left reel 21L by a combination of the winning symbol of the SCT1 combination and the right arrow.

  The SCT in-screen 720 shown in FIG. 10 is a notification effect screen that is displayed when the AT activation lottery executed in response to winning of the SCT1 role or the SCT2 role is won. The SCT screen 720 includes a status notification column 721 for notifying that an RT state with AT is a chance to occur, and a specific small role notification column indicating that winning of a single player will trigger an occurrence of an RT state with AT 722.

  The RT screen 730 shown in FIG. 11 is a notification effect screen for simultaneous winning of 10 winning combinations in the RT state during AT activation. The in-RT screen 730 includes a state notification column 734 for notifying that the RT state is occurring, a first stop notification column 731 for notifying the first stop reel corresponding to the 10-sheet combination A that does not require pressing, and RT A game number display field 732 for displaying the number of continuous games in a state and a difference number display field 733 for displaying a difference number (the number of payouts-injections) since the occurrence of the RT state are combined. This figure is an example of notification when the first stop reel corresponding to the 10-sheet combination A is the right reel 21R, such as when the 10-sheet combination A, B, and C are simultaneously won.

  The RT screen 740 shown in FIG. 12 is a notification effect screen at the time of simultaneous winning of 10 sheets in the RT state in which AT is not activated. The difference from the during-RT screen 730 is the notification content in the first stop notification column 741. In the first stop notification column 741, there are three? The marks are lined up, and the first stop reel corresponding to the 10-piece combination A is not notified. In the RT in-screen 740 of the same figure, only the fact that the simultaneous winning of 10 sheets has occurred is notified.

Next, the transition of the gaming state in the slot machine 1 will be described with reference to FIG. In the slot machine 1, the following game states occur.
(Normal state)
The normal state occurs in response to the end of any one of the RT state, the SCT1 state, and the SCT2 state. Also, the process ends in response to the occurrence of a bonus state corresponding to the winning of the bonus combination and the occurrence of the SCT1 state or SCT2 state corresponding to the winning of the SCT1 or SCT2 combination. The number of continuous games in the SCT1 state and the SCT2 state is one game. Therefore, when the transition from the SCT1 state or the SCT2 state to the RT state does not occur, the normal state is immediately restored. In the normal state, the following processing is executed according to the internal winning or winning of a predetermined combination.

At the time of simultaneous winning of the SCT1 role and the SCT2 role The simultaneous winning notification screen 710 (FIG. 9) is displayed on the liquid crystal display unit 53, whereby the stop order for winning the SCT1 role (first operation mode), and The stop order (second operation mode) for winning the SCT2 combination is notified.
-When winning the SCT1 role or SCT2 role The AT activation lottery using the AT activation lottery table is executed. In this AT activation lottery, as described above, the probability that the SCT2 combination wins is higher.
-At the time of internal winning of the replay role The transfer lottery using the transfer lottery table is executed. For example, when the transition to the AT low-accuracy state is won under the AT high-accuracy state, the transition to the AT low-accuracy state occurs. In the game of the slot machine 1 of the present example, it can be estimated to some extent whether the AT is in the high probability state or the AT low probability state in accordance with the winning of the replay combination A in the normal state.

(SCT1 state)
Occurs in response to winning SCT1 role. The SCT1 state continues only for one game. In the game under the SCT1 state, the pull-in range of only the middle reel 21C is limited to one symbol, and the pull-in ranges of the other reels 21L and 21R remain four symbols. When a single combination which is a specific small combination wins in the SCT1 state, a transition to the RT state occurs. If the AT activation lottery executed at the time of winning the SCT1 role is won, the fact is notified on the SCT screen 720 (FIG. 10).

(SCT2 state)
Occurs in response to winning SCT2. The SCT2 state continues only for one game. In the game under the SCT2 state, the pull-in range of each reel 21 is set to zero. Therefore, the level of difficulty in pushing in the SCT2 state is the highest level. When a single combination which is a specific small combination wins in the SCT2 state, a transition to the RT state occurs. When transitioning from the SCT2 state to the RT state, the degree of expectation for the AT is higher than when transitioning from the SCT1 state to the RT state. If the AT activation lottery executed at the time of winning the SCT2 winning is won, the fact is notified on the SCT in-progress screen 720 (FIG. 10).

(RT state)
The RT state occurs in response to winning of a single piece in the SCT1 state, the SCT2 state, etc., and ends in response to 50 games being consumed or winning of a bonus combination. When the AT activation lottery when the SCT1 role or the SCT2 role is won is won, the AT is activated together with the occurrence of the RT state. While the AT is activated, a notification effect is executed at the time of simultaneous winning of 10 sheets. In this notification effect, a first stop reel for winning a 10-piece combination A that does not require pressing is notified. In the RT state corresponding to the winning of a single player under the normal state, that is, the RT state that occurs without passing through either the SCT1 state or the SCT2 state, the AT is not activated.

(Bonus state)
There are a BIG bonus state that occurs in response to a BIG winning, and a REG bonus state that occurs in response to a REG winning. The end condition of the BIG bonus state is that the number of medals paid out exceeds 360. The termination condition for the REG bonus state is that the number of medals paid out exceeds 50. When these bonus states are finished, an RT state occurs.

  In the slot machine 1 configured as described above, the level of difficulty for winning a single role under the SCT2 state is higher than the level of difficulty for winning a single role under the SCT1 state. The RT state (second special game state) generated in accordance with the winning of one player in the SCT2 state reflecting the difficulty level of winning is higher in expectation for AT and more advantageous. Therefore, if the SCT1 role and the SCT2 role are elected at the same time, if it is a beginner or the like who does not have a sufficiently high level of skill, it is the trigger for the RT state that the SCT1 role is won and the SCT1 state is generated. It is easy to win a single winning combination. On the other hand, if it is an advanced person or the like who is good at pressing, it is better to challenge the winning of a single role by generating an SCT2 state by winning an SCT2 role. This is because if one winning combination can be won in the SCT2 state, an RT state with a high expectation for the AT can be generated.

  As described above, the slot machine 1 of the present example is less likely to be dissatisfied by beginners and fully enjoyed by advanced players when winning a single role that is an opportunity in the RT state that is advantageous to the player. It is a slot machine with an excellent gameplay ability.

This example is an example in which the AT activation lottery is executed at the time of winning the SCT1 role or the SCT2 role. Other timings may be set as the AT activation lottery execution timing. For example, the AT activation lottery can be executed when the transition to the RT state is confirmed in accordance with the winning of a single combination in the SCT1 state or the SCT2 state.
In this example, the AT high-accuracy state and the AT low-accuracy state with different expectations for the AT are set, but three or more states with different expectations for the AT can be set.

In this example, two types of SCT combination (SCT1 combination and SCT2 combination) are set. However, three or more types of SCT combinations may be set instead.
In this example, the number of continuing games in the SCT1 state and the SCT2 state is set to one game, but instead, the number of continuing games can be set to two or more games.

  In this example, a winning symbol of a single combination that is a specific small role is set as the specific symbol that triggers the transition to the RT state, but any combination of symbols may be used as the specific symbol. For example, a symbol combination that is stopped and displayed when a single combination that is a specific small combination is missed may be set as the specific symbol. Further, as the specific small combination, a small combination other than the one-sheet combination can be set.

In addition, this example is an example in which the SCT1 role and the SCT2 role are always won at the same time without being independently won internally. Instead, it is possible to set a case where at least one of the SCT1 combination and the SCT2 combination is won internally.
In addition, this example is an example in which either one wins according to the stop order at the time of simultaneous winning of the SCT1 role and the SCT2 role. Instead of this, either the SCT1 combination or the SCT2 combination may be awarded according to the operation timing of the stop button 61 regardless of the stop order.

  As described above, specific examples of the present invention have been described in detail as in the first embodiment, but these specific examples merely disclose an example of the technology included in the scope of claims. Needless to say, the scope of the claims should not be construed as limited by the configuration, numerical values, or the like of the specific examples. The scope of the claims includes techniques obtained by variously modifying or changing the specific examples using known techniques, knowledge of those skilled in the art, and the like.
