Description

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

  Conventionally, when a specific symbol is stopped in a normal state, an advantageous game state such as a highly probable RT state with a high internal winning probability of a replay role, or a low probable RT state with a low internal winning probability of a replay role There is a slot machine in which a transition to a gaming state with a low degree occurs (see, for example, Patent Document 1).

  In such a slot machine game, the winning probability of the replay role in the non-bonus state may change in accordance with the occurrence of the high-probability RT state or the low-probability RT state, and the player's advantage may change. If the player's advantage in the non-bonus state is changed, the monotony of the game can be eliminated to some extent, and the interest can be improved. Such a type of slot machine has a game property that when the number of games after transition from the normal state to another gaming state excluding the bonus state reaches a predetermined number of games, it returns to the normal state again. Slot machines have been proposed.

  However, the conventional slot machine having the gameability of returning to the normal state according to the digestion of the predetermined number of games has the following problems. That is, unless a transition to an advantageous gaming state such as a high-probability RT state occurs, an unfavorable gaming state such as a low-probability RT state and a normal state are repeated at a substantially constant cycle according to the predetermined number of games. In other words, there is a possibility that the change in the gaming state becomes monotonous and the interest cannot be kept high.

JP 2007-275377 A

  The present invention has been made in view of the above-described conventional problems, and makes it difficult to predict the arrival time of such a chance by randomly generating a chance to shift to an advantageous gaming state such as a highly probable RT state. It is an object of the present invention to provide a slot machine that can maintain a high tension and expectation of a player.

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;
Transition number determination means for determining in advance by lottery the number of transitions from the normal state to the first gaming state or the target number of transitions from the first gaming state to the normal state;
Transition number counting means for counting the number of transitions from the normal state to the first gaming state, or the number of transitions from the first gaming state to the normal state, and counting the actual number of transitions;
Notification determination means for executing notification lottery for determining whether to operate the notification means;
A notification control unit that operates the notification unit according to the determination by the notification determination unit to execute notification of at least one of the avoidance information and the assist information;
The notification determination means is updated each time the transition of the actual number of transitions reaches the target number of transitions after the transition number counting unit starts counting the actual number of transitions or after the notification lottery is executed. The slot machine is configured to execute the notification lottery (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 occurs in response to the stop display of the first specific symbol in the normal state. 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 by the operation of the notification means. is there.

  If there is a notification of the avoidance information, 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 game state can be shifted to the second gaming state. That is, in the slot machine, the notification of the avoidance information and the like gives a chance to shift to the second gaming state.

  In the slot machine of the present invention, the notification of the avoidance information or the assist information is executed when it is determined by the notification lottery that the notification means is to be operated. And the said notification determination means performs the said notification lottery whenever the increment of the said performance transfer frequency reaches the said target transfer frequency. In the slot machine game, the notification lottery for determining whether or not to operate the notification means is periodically executed according to the target number of times of transition.

  In the slot machine game, notification of the avoidance information and the like is determined at random timing based on a combination of a cycle in which the target number of times of transition is achieved and a frequency at which notification is determined by the notification lottery. Will be executed. Therefore, from the player side, it is very difficult to predict the timing at which notification of the avoidance information or the like occurs.

  In the game of the slot machine, a chance to shift to the second gaming state according to the notification of the avoidance information or the like occurs at a random timing that cannot be predicted from the player side. Therefore, the player can enjoy the game while always feeling a sense of tension and having a sense of expectation for the notification of the avoidance information and the transition to the second gaming state.

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.
Also, initialization determining means for determining whether or not to initialize the number of times of actual transfer;
When the initialization determining means determines initialization, it is preferable to include transition number initialization means for initializing the actual transition number so that the increment of the actual transition number at that time becomes zero. (Claim 2).
In this case, there is a possibility that the actual number of times of transition is initialized. When the actual number of times of transition is initialized, the timing at which the target number of times of transition is achieved is delayed, which is disadvantageous. Therefore, the player's tension can be further enhanced.

  In addition, as a method of initializing the actual number of times of transition so that the increment of the actual number of times of transition becomes zero, there are the following methods. For example, in the case where the increment value of the actual transition number is managed and the notification lottery is executed when the value reaches the target transition number, the increment value of the actual transition number is set to zero by initialization. It is good to set to. For example, in addition to the total number of actual transitions, the number of actual transitions at the time of the previous AT lottery is managed, and when the difference between them reaches the target number of transitions, the new notification lottery is executed. Initialization can be performed by setting the actual transition count at the previous AT lottery to the value of the actual transition count. If initialized in this way, the difference between the two at that time becomes zero.

  Furthermore, the initialization determination means can be configured to determine whether or not to initialize the number of times of achievement transition according to the game result in the normal state. In this case, the game result in the normal state is very important. Therefore, the player's tension can be maintained even in the normal state, and the interest can be enhanced.

In addition, it is preferable that the apparatus includes an effect execution means for executing effects with different contents depending on whether the result transition count is initialized and when the result transition count is not initialized. .
In this case, it becomes possible to suggest to the player whether or not the actual number of times of transition has been initialized by the production by the production execution means, and the interest of the game is further enhanced.

  According to the slot machine of the present invention, it is difficult to predict the arrival time of the chance by randomly generating a chance to shift to the advantageous second gaming state, and the player's tension and expectation are kept high. Is possible.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example relates to the slot machine 1 in which AT lottery is executed in accordance with the number of transitions from the low-probability RT state (first gaming state) to the normal state where the internal winning probability of the replay combination is low. 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 the low probability RT transition symbol (first specific symbol) that triggers the transition to the low probability RT state (first gaming state), and the winning symbol of the replay role D is high. It is a highly probable RT transition symbol (second specific symbol) that triggers the transition to the probable RT state (second gaming state). 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, the “sun” and “R” in the left reel 21L are always present within the draw-in range regardless of the timing of the stop operation, and are always displayed as stopped on the winning line as long as the corresponding winning combination can be won. It has become a design.

  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” in the right reel 21R are always present within the pull-in range regardless of the timing of the stop operation, and the corresponding role can be won. If there is any, it is a symbol that is stopped and displayed on the winning line.

  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 always exists 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 drawing 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 is always present within the draw-in range regardless of the timing of the stop operation, and is always stopped and displayed on the winning line when the corresponding winning combination is in a winning state. It has become.

  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, “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. The 10-piece combination B is a combination in which combination symbols are arranged at intervals that can be drawn on the winning line only on the left reel 21L. The 10-piece combination C is a combination in which combination symbols are arranged at intervals that can always be 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 only at the right reel 21R at intervals that can be drawn on the winning line.

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 types of gaming states that the slot machine 1 generates: 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. When a bonus combination wins in a non-bonus state, a bonus state occurs. 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 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 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 game state generating means 452 for generating a highly reliable RT state over the second continuation period (20 games), transition number determining means 46 for determining an AT lottery period, and the number of transitions from the low probability RT state to the normal state The transition number counting means 47 that counts the number of actual transitions by accumulating and the notification determination for executing the AT lottery (notification lottery) every AT lottery cycle Stage 48, to implement the functions as the notification control means 49 for actuating the alarm means 71 to perform the notification effect.

The RAM 34, which is a memory means, has a function of storing the actual number of transitions counted by the transition number counting means 47.
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 lottery of an internal winning combination, a periodic lottery table (FIG. 7) for determining an AT lottery period, and an AT used for AT lottery. A lottery table (FIG. 8) and a reel control table (not shown) used by the display control means 42 for stop control of the reels 21 are stored.
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 a range of winning random numbers for each combination is defined among the random numbers for internal winning combination 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. 7, the periodic lottery table is a table for determining an AT lottery cycle that is an AT lottery execution cycle. In the periodic lottery table, a winning random number among random numbers for periodic lottery ranging from 0 to 255 is set for each period from 0 to 20 periods. As the periodic lottery tables, there are an odd setting table for setting values 1, 3, and 5 and an even setting table for setting values 2, 4, and 6.

  As shown in FIG. 8, the AT lottery table is a table applied to an AT lottery for determining whether or not notification of avoidance information of the low probability RT transition symbol is executed. In the AT lottery table, winning random numbers among the random numbers for AT lottery in the range of 0 to 255 are set for each cycle from the 0th cycle to the 20th cycle. As the AT lottery tables, there are an odd setting table for setting values 1, 3, and 5 and an even setting table for setting values 2, 4, and 6. The number of winning random numbers in each cycle is slightly different between the even setting table and the odd setting table. As can be seen from the figure, the number of winning random numbers is all 256 for the zero period and the eleventh period and thereafter, and the AT lottery is won with a probability of 100%. As described above, in this example, the AT lottery period and the AT winning probability in each period are set to be different depending on whether the set value is even or odd. Therefore, it is possible to estimate to some extent whether the set value is an even number or an odd number by observing the winning status of the AT in each cycle.

  Here, the relationship between the period in the periodic lottery table and the period in the AT lottery table will be described. The period in the periodic lottery table and the AT lottery table is a non-AT period in which the normal state and the low probability RT state are periodically repeated until the subsequent low probability RT state ends after the normal state starts. It means a series of game periods. As will be described later, since the number of continuous games in the low-probability RT state is 64 games, the number of games in one cycle is the number of games obtained by adding the number of executed games in the normal state to the 64 games. And, for example, two AT lottery cycles in the periodic lottery table, three cycles,... Are the target transition times 2, 3,..., Which is the target value of the number of transitions from the low probability RT state to the normal state. It corresponds.

  On the other hand, the period in the AT lottery table means what period after the transition from the high-accuracy RT state to the normal state without AT. For example, from the start of the normal state without AT from the high-accuracy RT state to the end of the first low-accuracy RT state is the zero cycle, and after the start of the normal state according to the end of the first low-accuracy RT state The first period is until the second low-accuracy RT state is completed. For example, when three periods (AT lottery period) of the periodic lottery table are selected, AT lottery is executed in the third, sixth, and ninth periods in the AT lottery table.

  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 generator 350 includes a random number for internal winning combination lottery in the range of 0 to 65535, a random number for periodic lottery in the range of 0 to 255, and a range of 0 to 255. There are random numbers for the AT 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 in response to an operation of the start lever 62, and for periodic lottery triggered by a transition from a highly accurate RT state to a normal state without AT. And random numbers for AT lottery are extracted according to the start of the period corresponding to the AT lottery period.

  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 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 transition number counting unit 47 is a unit that counts the actual number of transitions by accumulating the number of transitions from the low probability RT state to the normal state. The transition number counting means 47 counts the actual number of transitions at zero start according to the transition from the highly accurate RT state to the normal state without AT. For example, after the transition to the normal state without AT, the transition to the normal state in the first cycle is the first transition, the transition to the normal state in the second cycle is the second transition, and the transition to the normal state in the third cycle The number of times of achievement transition is accumulated as the game progresses, such as the third transition.

  The transition count counting means 47 resets the counter value of the actual transition count stored in the RAM 34 to zero when the AT lottery is executed. Therefore, the counter value of the actual number of transitions stored in the RAM 34 means an increase in the actual number of transitions after the previous AT lottery is executed. Instead of this, the zero reset of the counter value of the RAM 34 for each AT lottery can be omitted. In this case, it is preferable to separately store the actual number of transitions in the previous AT lottery. A value obtained by subtracting the actual number of transitions at the previous AT lottery from the counter value of the actual number of transitions stored in the RAM 34 represents an increment of the actual number of transitions after the previous AT lottery is executed.

  The transition number determination means 46 is means for executing a periodic lottery for determining an AT lottery period. The transition number determination means 46 uses the random number for periodic lottery extracted by the random number extraction unit 35 at the time of transition from the highly accurate RT state to the normal state without AT, that is, the first game in the normal state. Run a lottery. The AT lottery cycle in this example means the target number of times of transition from the low probability RT state to the normal state. When the AT lottery cycle is 3 cycles, after the transition from the high-accuracy RT state to the normal state without AT, the transition to the first cycle normal state, the second cycle transition to the normal state, the third cycle normal The number of times of transition consisting of the transition to the state is the target number of times of transition. Note that the initial setting of the AT lottery cycle in this example is one cycle. Thereafter, a periodic lottery is executed every time the high-accuracy RT state shifts to the normal state without AT.

  The notification determination means 48 is a means for executing AT lottery (notification lottery) as to whether or not notification of avoidance information of the low probability RT transition symbol is executed. The notification determining means 48 executes the AT lottery in the first game in the cycle corresponding to the AT lottery cycle, that is, the first game after the transition to the normal state. If the AT lottery cycle is 3 cycles, that is, the target number of times of transition is 3, the AT lottery is executed in the first game in the normal state in the 3rd cycle. If the AT lottery is missed, the second AT lottery is executed in response to the transition to the normal state of the sixth cycle in which the actual number of times of transition reaches 3 times again.

  The notification determining unit 48 performs AT lottery by comparing the AT lottery random number extracted by the random number extraction unit 35 with the AT winning random number in the AT lottery table. When this AT lottery is won, an AT is immediately generated. If AT occurs, the avoidance information and the like are notified in the normal state, so that the transition to the high-accuracy RT state is relatively easy.

  Further, the notification determining means 48 of this example executes an AT continuous lottery for determining whether or not to continuously generate an AT. When the AT 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 AT 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 determination means 48 performs AT continuous lottery using a random number for internal lottery. Of the random numbers for internal lottery between 0 and 65535, 32768 are winning random numbers for AT continuous lottery, and the winning probability is ½ (50%).

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

  The notification means 71 is means for executing a notification effect while an AT is occurring. In the normal state, the notification means 71 performs notification of avoidance information for the replay combination A in accordance with 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. 9 and FIG. 10, the distribution of winning combinations according to the first stop reel when the 10-sheet combination and the replay combination are won simultaneously will be described. FIG. 9 shows the case of simultaneous winning of 10 winning combinations, and FIG. 10 shows the case of simultaneous winning of replay winning.
In the slot machine 1 of the present example, as described above, in the gaming state excluding the bonus state, there is a possibility that any two of the 10 winning combinations BD and 10 winning A will 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 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.

  As shown in FIG. 10, there are six types of replay role simultaneous winning patterns, such as replay role A and B simultaneous winning pattern, replay role A and C simultaneous winning pattern, and replay role A, B, and C simultaneously winning patterns. 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 wins. On the other hand, when the first stop reel is the left reel 21L, the replay combination B wins. 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, when the first stop reel is the left reel 21L or the right reel 21R in the simultaneous winning pattern of the replay combination A / B / D, the replay combination A wins. On the other hand, when the first stop reel is the middle reel 21C, the replay combination D wins. 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 with reference to FIGS.
A normal state screen 710 shown in FIG. 11 is a notification effect screen at the time of simultaneous winning of the replay role under the normal state during the occurrence of AT. 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. 11, the fact that the first stop reel corresponding to the replay combination D is the middle reel 21C is displayed. 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 RT screen 720 shown in FIG. 12 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. 13 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. When the bonus combination is won internally, even if the high-accuracy RT transition symbol and the low-accuracy RT transition symbol are stopped and displayed, there is no transition to the high-accuracy RT state or the low-accuracy RT state.

  When shifting from the high-accuracy RT state to the normal state without AT, a periodic lottery for determining an AT lottery cycle is executed. Thereafter, every time a period corresponding to the AT lottery period comes according to the progress of the game, the AT lottery is executed in the first game in the normal state belonging to the period. When an AT lottery is won, an AT is generated and avoidance information is notified. If AT occurs, the stop display of the low-accuracy RT transition symbol can be avoided, and a chance to shift to the high-accuracy RT state according to the stop display of the high-accuracy RT transition symbol is obtained.

(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 either the expiration of the first duration period over 64 games or the winning of a bonus combination. When the low-probability RT state ends due to the expiration of the first duration, the normal state is restored. In the low-probability RT state, when the period corresponding to the AT lottery period approaches, an effect (not shown) indicating that the AT lottery is approaching is executed. In the player, according to the suggestion effect that the AT lottery is approaching, the occurrence of AT, and thus the sense of expectation for the high-accuracy RT state is enhanced.

(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 possibility of shifting to the low probability RT state. The highly accurate RT state ends in response to either the expiration of the second continuation period over 20 games or the winning of a bonus combination. When the high-accuracy RT state ends due to the expiration of the second duration period, 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. 11). In the AT under the high probability RT state, the stop order for winning the 10-piece combination A is notified (see FIG. 12). 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 to avoid winning a single winning combination.

  When transitioning to the high probability RT state during the occurrence of AT, the AT 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 this AT continuation lottery is won, the AT will continue further 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 slot machine 1 of the present example configured as described above, when AT occurs in a normal state, the first stop reel (avoidance information) that draws other than the replay combination A whose winning symbol is a low-probability RT transition symbol. Informed. 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 occurs. 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.

  In the slot machine 1, AT lottery is executed in response to the start of a period corresponding to the AT lottery period (target number of transitions) determined by the transition number determination means 46. When an AT lottery is won, an AT is generated and a chance to shift to a highly accurate RT state is obtained. Thereafter, when the high-accuracy RT state shifts to the normal state without AT, a new AT lottery cycle is reset. In the slot machine 1 of this example, AT lottery, which is a chance of occurrence of AT, circulates at every AT lottery cycle determined by the transition number determining means 46. If this AT lottery is won, an AT is generated and the possibility of transition to the high-accuracy RT state is increased. That is, in the slot machine 1, a chance to shift to the high probability RT state arrives at a random timing based on a combination of the AT lottery cycle and the AT lottery. Therefore, in the game of the slot machine 1, the monotony of the game is suppressed and the interest is improved. Players can always play games with a sense of tension and expectation.

  As described above, according to the slot machine 1 of the present example, since an advantageous transition chance to the highly accurate RT state occurs at random timing, it is difficult to predict the arrival time of the chance as seen from the player side. Therefore, a sense of tension and high expectations are maintained.

  In this example, a new AT lottery cycle is set when the high-accuracy RT state shifts to the normal state without AT, and thereafter, the AT lottery cycle is maintained until the AT lottery is won. Instead, the AT lottery cycle may be changed and set before winning the AT lottery. For example, the AT lottery cycle can be changed and set when the BIG bonus or the REG bonus is won. If comprised in this way, prediction of AT lottery period will become still more difficult and interest will increase further.

In this example, the winning probability of each cycle in the periodic lottery and the winning probability of each cycle in the AT lottery are between the odd setting (1, 3, 5) and the even setting (2, 4, 6). Is different. Instead, different winning probabilities can be set for each set value.
Further, in this example, the AT lottery is not executed in a cycle that does not correspond to the AT lottery cycle, but instead, the case where the AT lottery is executed even in a cycle that does not correspond to the AT lottery cycle may be set. good. In this case, it is preferable that the winning probability in the AT lottery in a period not corresponding to the AT lottery period is set lower than the winning probability in the AT lottery in the period corresponding to the AT lottery period. It is preferable to set a difference between an AT occurrence probability in a period corresponding to the AT lottery period and an AT occurrence probability in a period not corresponding to the AT lottery period.
In this example, the AT lottery execution timing is controlled using the number of transitions from the low-probability RT state to the normal state. Alternatively, the AT lottery execution timing can be controlled using the number of transitions from the normal state to the low probability RT state.

  In this example, if the AT lottery is not won, no AT is generated in the normal state. Instead, the AT is generated in the normal state even if the AT lottery is not won. It is also good to set. 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.
Further, the transition number determination means 46 of the present example is configured to execute a periodic lottery when transitioning from the highly accurate RT state to the normal state without AT. In addition to this, the periodic lottery may be executed similarly when the bonus state is shifted to the normal state without AT.

  Note that the number of continued 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 particular, if the number of continuous games in the low-probability RT state is too long, it is difficult to maintain the player's sense of tension and expectation.

In addition, this example is an example in which the 10-sheet combination is not won internally by itself and any three of the 10-sheet combinations A to D are simultaneously won. You may add the case where each of 10-sheet combination AD is independently won internally. When any 10 winning combination is won, it becomes possible to win the 10 winning combination regardless of the first stop reel.
In this example, dedicated random numbers for periodic lottery and AT lottery are set. Alternatively, a random number for internal winning combination lottery can be used for periodic lottery, AT lottery, or the like.

  In addition, about the present example in which the AT lottery is executed when the actual transition number reaches the target transition number, a case where the actual transition number is initialized and reset to zero may be set. By adding an initialization determining means for determining whether or not to initialize the actual number of times of transition, and a transition number initializing means for initializing the actual number of transitions according to the initialization determination by the initialization determining means, As described above, it is possible to set a case where the actual number of transitions is reset to zero. In this case, the AT lottery execution timing becomes further random, and the prediction by the player becomes more difficult. It is also possible to set an effect execution means that suggests that initialization has been determined and the number of results transition has been initialized.

  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.
