Description

  The present invention relates to a slot machine in which a gaming state with a low degree of advantage and a gaming state with a high degree of advantage are set as a non-bonus state.

  Conventionally, for example, a low probability RT state with a low probability of winning a replay role is set as a gaming state having a lower advantage than the normal state, while a winning probability of a replay role is higher as a gaming state having a higher advantage than the normal state. A slot machine in which a highly accurate RT state is set is known (for example, see Patent Document 1).

  As such a slot machine, there is a slot machine configured to return to a normal state when the number of digested games after the transition to the high probability RT state or the low probability RT state reaches a predetermined number of games. This type of slot machine eliminates the monotony of the game by setting up a low-accuracy RT state and a high-accuracy RT state in addition to the normal state, thereby raising and lowering the player's advantage in the non-bonus state. Is trying to increase.

However, the conventional slot machine has the following problems. That is,
When a game state with a low degree of advantage such as the low probability RT state is entered, it is impossible to return to the normal state unless the predetermined number of games is exhausted. Therefore, the player's willingness to play suddenly decreases due to the transition to a game state with a low degree of advantage. However, there is a risk of stopping the game.

JP 2007-275377 A

  The present invention has been made in view of the above-mentioned conventional problems, and is less advantageous by improving the gameability after transitioning to a gaming state where the player's advantage is low, such as a low-probability RT state. It is an object of the present invention to provide a slot machine that can maintain a player's willingness to play even while the gaming state continues.

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;
An internal lottery means for executing an internal lottery for determining an internal winning combination from a plurality of types of combinations when the game start operation means is operated;
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 drawing range and stopping and displaying it in the symbol display area;
Winning determination means for determining whether or not 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;
When the combination of symbols stopped and displayed in the symbol display area in the normal state is the first specific symbol, the first gaming state is generated over a predetermined first duration, and the first duration is First game state generating means for returning to the normal state when the time has elapsed;
When the combination of symbols stopped and displayed in the symbol display area in the normal state is the second specific symbol, the player's degree of advantage over the first gaming state is greater than the first gaming state over a predetermined second duration. A second gaming state generating means for generating a high second gaming state and returning to the normal state when the second duration has elapsed;
Informing means capable of informing the player of at least one of avoidance information for avoiding the stop display of the first specific symbol and assist information for stopping and displaying the second specific symbol;
A notification lottery period in which a notification lottery for determining whether to perform notification of at least one of the avoidance information and the assist information by the notification means is executed, and a notification lottery condition in the notification lottery Period setting means for setting a lottery preparation period for determination within the first duration period;
In the lottery preparation period, notification lottery condition determining means for determining the notification lottery condition;
In the notice lottery period, notice lottery means for executing the notice lottery based on the notice lottery condition determined by the notice lottery condition determining means;
When the first gaming state ends and returns to the normal state, the notification is performed so that at least one of the avoidance information and the assist information is notified in accordance with the winning in the notification lottery. And a notification control means for controlling the means (claim 1).

  The first gaming state in the slot machine of the present invention is a gaming state in which the player's degree of advantage is lower than that in the second gaming state. The transition to the first gaming state can occur in response to the stop display of the first specific symbol. In the slot machine, the avoidance information for avoiding the stop display of the first specific symbol or the assist information for stopping and displaying the second specific symbol may be notified. If the avoidance information is notified, the stop display of the first specific symbol can be avoided, and the transition to the first gaming state can be avoided. If the transition to the first gaming state can be avoided, the possibility of transition to the second gaming state having a relatively high degree of advantage can be improved. If the assist information is notified, the second specific symbol can be stopped and displayed while avoiding the first specific symbol, and the transition to the second gaming state becomes possible.

  In the first continuation period in the slot machine of the present invention, the notification lottery period in which the notification lottery for determining whether to perform notification of the avoidance information or the like is executed, and the notification lottery condition are determined. The lottery preparation period is set. That is, in this slot machine, after the transition to the first gaming state, the lottery preparation period for determining the notification lottery condition arrives, and the notification lottery condition is determined within that period. In the notification lottery period, the notification lottery based on the determined notification lottery condition is executed.

  In the lottery preparation period, a player's expectation for a more advantageous notification lottery condition can be obtained. Furthermore, in the notification lottery period, a player's expectation for the notification lottery can be given. Therefore, according to this slot machine, as the return timing to the normal state approaches through the lottery preparation period and the notification lottery period, the player's expectation for winning in the notification lottery is gradually increased. I can talk. If there is a notification such as the avoidance information according to the winning in the notification lottery, the possibility of transition to the second gaming state is increased. Therefore, in the game of the slot machine, as the return timing from the first gaming state to the normal state approaches, the player's expectation for the occurrence of the second gaming state can be increased step by step.

  As described above, according to the slot machine of the present invention, the gameability in the first gaming state having a low degree of advantage is improved, and the player's willingness to play is maintained high even while the first gaming state continues. It is possible.

  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 notification lottery condition determining means determines any one of a plurality of types of conditions in which at least one of the length of the notification lottery period and the winning probability in the notification lottery is different as the notification lottery condition. (Claim 2).
If the winning probability in the notification lottery is different, the expectation per notification lottery may vary. If the length of the notice lottery period, that is, the number of games executed in the notice lottery period is different, the number of notice lotteries is different, and even if the winning probability in one notice lottery is the same, the notice lottery period The expectation degree won in the notice lottery at the end of will vary.

Further, when the first gaming state is ended and the normal state is restored, the notification control unit performs the notification of the avoidance information and the assist information according to the winning in the notification lottery. It is preferable to control the means (claim 3).
In this case, according to the winning in the notification lottery, the transition to the second gaming state after returning to the normal state is further facilitated. Therefore, the player's expectation for the second gaming state can be further enhanced as the return timing to the normal state approaches.

  It is also possible to determine whether the avoidance information is notified or the assist information is notified in the notification lottery. When the notification of the assist information is determined, it is possible not only to avoid the transition to the first gaming state but also to shift to the second gaming state, which is more advantageous for the player.

  The slot machine of the present invention improves the gameability after transitioning to a gaming state with a low degree of advantage on the player side, such as a low-probability RT state, so that even if the gaming state with a low degree of advantage continues, It is a slot machine with excellent characteristics that can maintain the willingness to play.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example is a slot machine capable of generating a high probability RT state (second gaming state) with a high internal winning probability of a replay role and a low probability RT state (first gaming state) with a low internal winning probability of a replay role. 1 is an example. 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 the non-bonus state, which is a three-wager game, a 3-bet signal indicating the number of insertions 3 is generated in response to the operation of the bet button 64. On the other hand, in the two-wager bonus state, a 2-bet signal is generated according 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 the 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 later 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 normal state screen 710 and an RT in-progress screen 720 displayed by a notification unit 71 (see FIG. 5) described later. The contents of the normal state screen 710 and the in-RT screen 720 will be described later in detail 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, a bonus combination (BIG, REG), a plurality of types of small combinations including 10 combination combinations A to D, and replay combinations A to D 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-sheet combination A to D and the replay combination 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.

  The winning symbol of the replay role A is a doublet of the symbol “R”. If the right reel 21R is replaced with the symbol “cherry” based on the winning symbol of the replay role A, the winning symbol of the replay role B is obtained by replacing the right reel 21R with the symbol “sun”, and the winning symbol of the replay role C is obtained. If the left reel 21L and the right reel 21R are replaced with the symbol “sun”, the winning symbol of the replay combination D is obtained. Here, the winning symbol of the replay role A is a low probability RT transition symbol (first specific symbol) that triggers the transition to the low probability RT state, and the winning symbol of the replay role D is transitioned to the high probability RT state. It is a highly reliable RT transition symbol (second specific symbol) as an opportunity. In addition to the winning symbol for the replay combination A, the winning symbol for one combination is set as the low probability RT transition symbol.

In each reel 21L, C, R, symbols are arranged as shown in FIG.
In the left reel 21L, the maximum interval of the symbol “sun” and the maximum interval of the symbol “R” are both 6 symbols. Here, in the slot machine 1 of this example, as described later, a range corresponding to four symbols is set as a pull-in range when the reel 21 stops. In addition, as described above, in the symbol display area 110L, a winning line is set for three symbols in the upper middle stage and the lower stage. Therefore, “sun” and “R” in the left reel 21L are always present within the drawing range regardless of the timing of the stop operation, and are symbols that can be stopped and displayed on the winning line.

  In the right reel 21R, the maximum interval of the symbol “sun”, the maximum interval of the symbol “cherry”, and the maximum interval of the symbol “R” are all 6 symbols. As in the case of the left reel 21L, the “sun”, “cherry”, and “R” on the right reel 21R are always present within the drawing range regardless of the timing of the stop operation, and can be stopped and displayed on the winning line. It has become.

  In the left reel 21L and the right reel 21R, the maximum interval of a specific type of symbol “orange” is 13 symbols or more, and the maximum interval in any type is 6 symbols. Therefore, one of the two types of “orange” in the left reel 21L and the right reel 21R can always exist 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 61 with good timing.

  In the middle reel 21C, the maximum interval of the symbol “R” is 4 symbols. The pull-in range when the reel 21 is stopped is for 4 symbols. On the other hand, in the symbol display area 110C as described above, a winning line is set for only one symbol in the middle stage. Therefore, “R” in the middle reel 21C always exists in the drawing range regardless of the timing of the stop operation, and has a pattern that can be stopped and displayed on the winning line.

  In the middle reel 21C, for two types of “orange”, 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, “orange” in the middle reel 21C does not need to be pressed unless it is of any kind, while a specific type of “orange” has a pattern that requires pressing.

  From the above, the 10-piece combination A in the slot machine 1 of the present example is a combination in which combination symbols are arranged at intervals that can be drawn on the winning line in all the reels 21. In the 10-piece combination B, only the left reel 21L is a combination in which combination symbols are arranged at intervals that can be drawn on the winning line. The 10-piece combination C is a combination in which combination symbols are arranged at intervals that can be surely drawn on the winning line only in the middle reel 21C. The 10-piece combination D is a combination in which combination symbols are arranged at intervals that can be surely drawn on the winning line only on the right reel 21R.

Each of the replay roles A to D is a role that can always be won when an internal winning is made independently. However, as will be described later, when two or more types of replay winning combinations are simultaneously won internally, the replay winning combinations that can be won vary according to the order of stop operation among the three stop buttons 61L, C, R. It has become.
As with the replay role A winning symbol, for the single symbol winning symbol “Black 7-BAR-White 7”, which is a low-probability RT transition symbol, stop display is avoided by performing a stop operation in a timely manner. Is possible.

  Next, the outline of the playability of the slot machine 1 of this example will be described. There are four game states generated by the slot machine 1: a normal state, a high probability RT state, a low probability RT state, and a bonus state. The bonus state includes a BIG bonus state and a REG bonus state.

  The BIG bonus state is the most advantageous gaming state that occurs in response to a BIG winning. This BIG bonus state ends when the number of medals paid out exceeds 360. The REG bonus state is an advantageous gaming state that occurs in response to a REG winning. This REG bonus state ends when the number of medals paid out exceeds 50. When these bonus states are completed, the normal state, which is the initial state, is restored.

  In the slot machine 1 of this example, the normal state, the high probability RT state, and the low probability RT state are non-bonus states. If a bonus combination wins in a non-bonus state, a bonus state can occur. The high-accuracy RT state and the low-accuracy RT state are generated according to the stop display of the high-accuracy RT transition symbol and the low-accuracy RT transition symbol in the normal state which is the initial state. The high probability RT state is advantageous to the player because the internal winning probability of the replay role is higher than the low probability RT state.

  In the normal state, an AT may be generated in which avoidance information of the low-accuracy RT transition symbol is notified. In the AT under the normal state, the possibility of shifting to the low probability RT state is suppressed, and the possibility of transition to the relatively high probability RT state is increased. 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 set values of 6 stages 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 in accordance with the winning, first game state generating means 451 for generating a low probability RT state over the first duration (64 games) , Second gaming state generating means 452 for generating a highly reliable RT state over the second continuation period (20 games), AT lottery period (notification lottery period) and AT lottery condition determination period (lottery preparation period) in the first continuation period Period setting means 46 for setting the information, and the lottery condition for determining the AT lottery condition (notification lottery condition) in the AT lottery condition determining period Determining means 47, AT lottery alarm lottery means for executing AT lottery (annunciation lottery) in the period 48 to implement the functions as the notification control unit 49 to execute the notification effect the notification means 71.

The ROM 33, which is a memory means, has an internal winning combination lottery table (FIG. 6) used by the internal lottering means 41 for the internal winning combination lottery, and a reel control table (not shown) used by the display control means 42 for the stop control of the reel 21. I remember it.
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 shown in FIG. 6, the internal winning combination lottery table is a data table in which the range of the winning random number of each combination is defined among the random numbers for internal lottery of 0 to 65535. As the internal winning combination lottery table, there are a table applied to a normal state, a table applied to a low probability RT state, a table applied to a high probability RT state, and a table applied to a bonus state (not shown). An internal winning combination lottery table for each gaming state excluding the bonus state is prepared for each set value. 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, the low probability RT state, and the high probability RT state, the winning random numbers of the roles other than the replay role are common, but the setting of the winning random numbers of the replay role is different. In the table for the normal state, only random numbers for which two or more types of replay combinations are won simultaneously are set. In the table for the normal state, the internal winning probability of any of the replay roles is 1 / 1.5, and the internal winning probability of the replay role D that triggers the highly accurate RT state is about 1/22.

  In the table for the low-probability RT state, the replay combination A is set with a random number for internal winning alone and a random number for which at least two of the replay combinations A to C are simultaneously selected. No random number is set for winning internally. In the table for the low probability RT state, the internal winning probability of any replay combination is 1 / 7.3. In the table for the high-accuracy RT state, simultaneous winning random numbers for two or more types of replay roles are not set, but only random numbers for which the replay role A is independently won are set. The internal winning probability of the replay role A alone is 1 / 1.5.

  As shown in FIG. 5, the random number extraction unit 35 is a part for extracting a random number for internal lottery and a random number for distributing an AT lottery period. 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 is a part that generates an integer belonging to a predetermined range. The random number extraction unit 35 extracts an integer generated by the random number generation unit 350 as a random number. As random numbers, random numbers for internal lottery in the range of 0 to 65535 for the internal lottery means 41 to draw the internal winning combination and AT lottery periods in the range of 0 to 63 for lottery of the AT lottery period are used. There are random numbers.

  As shown in FIG. 5, 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 random numbers for internal lottery against the winning random numbers of each combination specified in the internal winning combination lottery table (FIG. 6), and determines 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 notification lottery condition determining means 47 is a means for determining an AT lottery condition in the AT lottery condition determining period. The AT lottery condition determined by the notification lottery condition determining means 47 is a condition consisting of a combination of whether or not the AT lottery is executed in the AT lottery period and the length of the AT lottery period. The notification lottery condition determining means 47 determines whether or not to execute the AT lottery using a random number for internal lottery. Specifically, when the random number for internal lottery is a predetermined AT lottery winning random number, it is determined that the AT lottery is executed. The AT lottery winning random numbers are all 500 winning random numbers of 3 doubles, 600 of 1135 winning random numbers of 2 doubles, 1000 of 6000 winning random numbers of 1 double, 2100 in total. Yes. That is, 2100 of the random numbers for internal lottery from 0 to 65535 are AT lottery winning random numbers, and the winning probability is 1 / 31.2.

  When it is determined that the AT lottery is to be executed, the notification lottery condition determining unit 47 determines the length of the AT lottery period by lottery. The notification lottery condition determining means 47 selectively determines the AT lottery period using the AT lottery period distribution random number. As shown in FIG. 7, a predetermined number of winning random numbers are set for each AT lottery period of 32, 16, 8, and 4 games. For example, eight winning random numbers are set for the AT lottery period of 16 games, and therefore the winning probability of 16 games is 8/64.

  The notification lottery means 48 is means for executing AT lottery based on the AT lottery conditions. The notice lottery means 48 performs AT lottery using a random number for internal lottery. Specifically, any one of the simultaneous winning random numbers of the replay roles A and B, the simultaneous winning random numbers of the replay roles A and C, and the winning random numbers of the replay roles A, B, and C is extracted, and the replay role B or When C wins, it will be won in the AT lottery. When the AT lottery is won, AT occurs after returning to the normal state. The notification lottery means 48 executes the AT lottery for each game executed in the AT lottery period based on the AT lottery conditions.

  Furthermore, the notification lottery means 48 of the present example executes a continuous lottery as to whether or not to continuously generate ATs. When the continuous lottery is won, AT is continuously generated when returning to the normal state in response to the end of the high-accuracy RT state with AT. The continuous lottery is executed in the first game when the AT is generated and the state is shifted to the high-accuracy RT state. Specifically, the notification lottery means 48 performs continuous lottery using a random number for internal lottery. Of the random numbers for internal lottery from 0 to 65535, 51,000 are random numbers for continuous lottery, and the winning probability is 1 / 1.29 (78%).

  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, as described above, a range corresponding to four symbols is set as the pull-in 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 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, when the bonus combination is a winning combination, the profit granting unit 44 provides a profit that a bonus state occurs. In addition, for example, when the three winning combination is a winning combination, a benefit of paying out three medals is given.

  The first game state generating means 451 is a means for generating a low probability RT state that is disadvantageous to the player. The low probability RT state occurs when a low probability RT transition symbol such as a winning symbol of the replay combination A is stopped and displayed in the normal state. The duration of the low probability RT state (first duration) is 64 games. The first game state generation means 451 ends the low-probability RT state and returns to the normal state when the first duration period expires in accordance with the digestion of 64 games.

  The second gaming state generating means 452 is a means for generating a highly reliable RT state that is advantageous to the player. The highly accurate RT state occurs when the winning symbol of the replay combination D, which is the highly accurate RT transition symbol, is stopped and displayed in the normal state. The duration of the highly accurate RT state (second duration) is 20 games. The second gaming state generating means 452 ends the high-probability RT state and returns to the normal state when the second continuation period expires according to the digestion of the 20 games.

  The period setting means 46 is a means for setting an AT lottery condition determination period and an AT lottery period for the first continuation period in the low-probability RT state over 64 games. The AT lottery condition determination period is a period during which the notification lottery condition determination means 47 determines the AT lottery condition. The AT lottery period is a period in which the notice lottery means 48 performs AT lottery based on the AT lottery conditions determined in the AT lottery condition determination period. The period setting means 46 sets the first half 32 games of the first continuation period as the AT lottery condition determination period. Further, according to the AT lottery condition determined by the notification lottery condition determining means 47, a part or all of the latter half 32 games of the first continuation period is set as the AT lottery period.

  The notification control means 49 is means for controlling the notification means 71. The notification control means 49 causes the notification means 71 to execute a notification effect during the occurrence of AT. The AT is generated in response to the return to the normal state when the AT lottery executed during the AT lottery period is won. When the normal state with AT shifts to the high-accuracy RT state, the AT continues as it is. Further, when the continuous lottery at the time of transition to the highly accurate RT state is won, AT is continuously generated when returning to the normal state.

  The notification means 71 is means for executing a notification effect while an AT is occurring. In the normal state, the notifying unit 71 notifies the avoidance information of the replay combination A according to the simultaneous winning of the replay combination. Specifically, the first stop reel for avoiding the winning of the replay combination A whose winning symbol is the low probability RT transition symbol is notified as the avoidance information.

  In the highly accurate RT state, the notifying means 71 performs a notification effect for winning a 10-sheet combination A that does not require pressing and can be surely won when the 10-sheet combination is won simultaneously. Specifically, the first stop reel for winning the 10-sheet combination A is notified.

Here, with reference to FIG. 8 and FIG. 9, description will be given of the allocation of winning combinations according to the first stop reel when the 10-sheet combination and the replay combination are won simultaneously. FIG. 8 shows the case of simultaneous winning of 10 sheets, and FIG. 9 shows the case of simultaneous winning of replay.
In the slot machine 1 of this example, as described above, in the gaming state excluding the bonus state, any two of the ten-card combinations B to D and the ten-card combination A can be won simultaneously. 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 the 10-sheet combination A, B, and C are simultaneously won, the 10-sheet combination B combination symbol can stop on the winning line when the first stop reel is the left reel 21L. When the first stop reel is the middle reel 21C, the 10-piece C combination symbol can stop on the winning line. When the first stop reel is the right reel 21R, the winning symbol of 10 sheets A can be stopped on the winning line.

  As shown in FIG. 9, there are 6 types of simultaneous winning patterns for replay roles, such as simultaneous winning patterns for replay roles A and B, simultaneous winning patterns for replay roles A and C, and winning patterns for replay roles A, B, and C. The simultaneous winning pattern is set. In each simultaneous winning pattern, as shown in the figure, the replay winning combination is assigned according to the first stop reel. For example, when the first stop reel is the middle reel 21C or the right reel 21R in the simultaneous winning pattern of the replay combinations A, B, and C, the replay combination A can win. On the other hand, when the first stop reel is the left reel 21L, the replay combination B can win. At this time, the fact that the left reel 21L should be the first stop reel is avoidance information for avoiding the stop display of the winning symbol of the replay combination A which is the low-probability RT transition symbol.

  Further, for example, if the first stop reel is the left reel 21L or the right reel 21R in the simultaneous winning pattern of the replay combinations A, B, and D, the replay combination A can win. On the other hand, when the first stop reel is the middle reel 21C, the replay combination D can win. At this time, the fact that the middle reel 21C should be the first stop reel is not only the above avoidance information, but also assist information for assisting the stop display of the winning symbol of the replay combination D, which is a highly accurate RT transition symbol.

Next, the normal state screen 710, the in-RT screen 720, and the in-RT screen 730 that are displayed on the liquid crystal display unit 53 by the notification unit 71 when simultaneous winning occurs will be described using FIGS.
A normal state screen 710 shown in FIG. 10 is a notification effect screen at the time of simultaneous winning of the replay role under the normal state during AT occurrence. The normal state screen 710 is an example of a display screen based on a notification effect executed by the notification means 71 when the replay combination A, B, and D are simultaneously won in the normal state during the occurrence of AT.

  The normal state screen 710 includes a first stop notification column 711 for notifying the first stop reel corresponding to the replay roles B to D, a loop number display column 712 for displaying the number of loops (continuous number of times) in the highly accurate RT state, A difference number display field 713 for displaying the difference number (the number of payouts-the number of inputs) since the first highly accurate RT state is started is combined. In the example of FIG. 10, it is displayed that the first stop reel corresponding to the replay combination D is the middle reel 21C. The first stop notification column 711 in the same figure notifies avoidance information for avoiding winning of the replay combination A, and also notifies assist information for winning the replay combination D.

  The in-RT screen 720 shown in FIG. 11 is a notification effect screen at the time of simultaneous winning of 10 winning combinations in the highly accurate RT state during the occurrence of AT. The RT in-progress screen 720 includes a state notification column 724 for notifying that a highly probable RT state is occurring, and a first stop notification column 721 for notifying the first stop reel corresponding to the 10-piece combination A that does not require pressing. A loop number display field 722 for displaying the number of loops (continuation number) in the high-accuracy RT state, and a difference number display for displaying the difference number (payout number-injection number) since the first high-accuracy RT state is started. And a column 723. 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 in-progress screen 730 shown in FIG. 12 is a notification effect screen for simultaneous winning of 10 sheets in the high-accuracy RT state during which AT is not occurring. The difference from the during-RT screen 720 is in the first stop notification column 731. In the first stop notification column 731, 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 730 in the figure, only the fact that the simultaneous winning of 10 sheets has been generated 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 after the bonus state ends. Ends in response to stop display of high-accuracy RT transition symbol (replay role D winning symbol) and low-accuracy RT transition symbol (replay role A and single-race winning symbol), to high-accuracy RT state and low-accuracy RT state Occurs. In the normal state, the probability that any replay combination will win internally is 1 / 1.5.

(Low accuracy RT state)
The low probability RT state is an unfavorable gaming state in which the internal winning probability of the replay combination is set low as 1 / 7.3. This low probability RT state ends in response to the expiration of the first duration period over 64 games. When the low probability RT state ends, the normal state is restored. In the first continuation period, the first half 32 games are set as the AT lottery condition determination period, and part or all of the latter half 32 games are set as the AT lottery period.

  In the AT lottery condition determination period, AT lottery conditions including whether to perform AT lottery are determined. In this example, when it is determined that the AT lottery is to be executed, the length of the AT lottery period is determined. The AT lottery condition in this example is a condition formed by a combination of whether or not to execute the AT lottery and the length of the AT lottery period. One of 4, 8, 16, and 32 games is selected as the length of the AT lottery period. Note that instead of or in addition to this example, the winning probability per one AT lottery can be determined as the AT lottery condition.

  In the AT lottery period, AT lottery is executed based on the AT lottery conditions determined in the AT lottery condition determination period. In the AT lottery period, AT lottery based on AT lottery conditions is executed for each game. In this example, when the replay role A / B is simultaneously selected, the replay role A / C is simultaneously selected, and when the replay role A / B / C is simultaneously selected, the replay role B or the replay role C is selected by the AT lottery. Will be won.

(High accuracy RT state)
The high probability RT state is advantageous over the normal state in that the internal winning probability of the replay combination is 1 / 1.5, which is the same as the normal state, but there is no risk of shifting to the low probability RT state. The highly accurate RT state ends in response to the expiration of the second duration period over 20 games. When the high-accuracy RT state ends, the normal state is restored.

(AT)
In the normal state and the high-accuracy RT state, an AT in which a notification effect is executed may occur together. In the AT under the normal state, a stop order (avoidance information) for avoiding winning of the replay combination A whose winning symbol is a low-probability RT transition symbol is notified (see FIG. 10). In the AT under the high-definition RT state, the stop order for winning the 10-piece combination A is notified (see FIG. 11). If an AT has occurred in the normal state, the AT is continued after the transition to the high-accuracy RT state. In addition, when a single winning combination that is a low-probability RT transition symbol is won internally, a notice to that effect may be issued to urge attention not to win a single winning combination.

  When a transition to the high probability RT state occurs during the occurrence of AT, the continuous lottery for determining whether or not to continue the AT is executed in the first game after the transition to the high probability RT state. If the continuous lottery is won, the AT can be further continued in the normal state after the high probability RT state ends. Note that the AT in the normal state may notify only one of the avoidance information and the assist information.

  In the game of the slot machine 1 of the present example configured as described above, after the transition to the low probability RT state (first game state), first, an AT lottery condition determination period for determining the AT lottery conditions arrives. The AT lottery conditions are determined within the period. After the AT lottery conditions are determined, an AT lottery period in which the AT lottery is actually executed comes. When an AT lottery is won, an AT can occur when returning to the normal state.

  When AT occurs in the normal state, a first stop reel (avoidance information) that draws other than the replay combination A is notified. In the normal state with AT, the winning of the replay combination A is avoided according to the notification, and the low winning RT state is achieved by pushing the winning symbol so that the single winning combination whose winning symbol is the low-probability RT transition symbol is not won as described above. It is possible to wait for the transition to the high-accuracy RT state while avoiding the transition. If the high-accuracy RT state can be shifted as it is, a high-accuracy RT state with AT can occur. In the high-accuracy RT state with AT, it is very advantageous because the first stop reel that pulls in the 10-piece combination A that does not need to be pushed and can be surely won is notified.

  As described above, in the slot machine 1 of this example, the AT lottery for determining whether or not to generate an AT after the return to the normal state is executed in the low-probability RT state. Therefore, in the low-accuracy RT state, as the return timing to the normal state approaches, it is possible to gradually increase the expectation for the AT and the expectation for the high-accuracy RT state where the possibility of transition increases according to the AT.

  Furthermore, the AT lottery of this example executed in the low probability RT state is not simple. In the low probability RT state, an AT lottery condition determination period for determining the AT lottery condition and an AT lottery period in which the AT lottery is actually executed are set separately in the first half. According to the slot machine 1, an expectation for the AT lottery condition of favorable conditions can be obtained during the AT lottery condition determination period in the first half, and an expectation for the AT lottery can be obtained during the subsequent AT lottery period. As described above, during the occurrence of the low probability RT state, it is possible to gradually increase the player's expectation for the AT and the high probability RT state.

  As described above, the slot machine 1 of the present example is continuing the gaming state with a low degree of advantage by improving the gameability after the transition to the gaming state with a low degree of advantage on the player side such as a low-probability RT state. However, it is a slot machine with excellent characteristics that can maintain the player's willingness to play.

  In this example, the length of the AT lottery period is determined as the AT lottery condition. In addition to the length of the AT lottery period, the winning probability of the AT lottery may be determined as the AT lottery condition. Furthermore, while fixing the length of the AT lottery period, only the winning probability of the AT lottery may be determined as the AT lottery condition.

  Also, in this example, if the AT lottery is not won, no AT will occur in the normal state. Instead, an AT will occur after returning to the normal state even if the AT lottery is not won. It is also possible to provide a case. For example, an AT lottery may be separately performed when the replay combination A is internally won in the normal state, and an AT may be generated in response to the winning.

In this example, when the normal state without AT is shifted to the high-accuracy RT state, the first stop reel of the 10-piece combination A is not notified, but instead, the first of the 10-piece combination A is the first. You may set the case where a stop reel is alert | reported.
In this example, the winning symbol of the replay combination A and the single-player combination is set as the low probability RT transition symbol, and the winning symbol of the replay combination D is set as the high probability RT transition symbol. Such a symbol combination may be used.
Furthermore, the number of continuing games (first duration and second duration) in the low probability RT state and the high probability RT state can be set as appropriate. It is not limited to 64 games and 20 games of this example.

  In this example, AT lottery is executed for each game during the AT lottery period. Instead, the AT lottery may be executed every time a predetermined number of games such as two games, three games, etc. are executed, or the AT lottery may be executed every time a predetermined condition is satisfied in the AT lottery period. . As this predetermined condition, for example, various conditions can be set, such as that a specific combination has won an internal winning or winning, or has won a preliminary lottery executed for each game.
