Description

  The present invention relates to a slot machine capable of generating a gaming state having a lower advantage than a normal state and a gaming state having a higher advantage in 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).

  In this slot machine game, a transition from a normal state to a high-probability RT state or a low-probability RT state occurs when a specific symbol is stopped. When the number of digested games after transitioning to each RT state reaches a predetermined number of games, the normal state is restored again. Such a slot machine eliminates the monotony of the game by setting up a low-probability RT state and a high-probability RT state in addition to the normal state, thereby giving rise to the player's advantage in the non-bonus state. Is trying to increase.

  However, the conventional slot machine has the following problems. In other words, the transition to the gaming state with a low degree of advantage becomes clear by the stop display of the specific symbol, and the player knows that it cannot return to the normal state unless the predetermined number of games is consumed. As a result of this transition, the player's willingness to play decreases rapidly, and the game may be stopped.

JP 2007-275377 A

  The present invention has been made in view of the above-mentioned conventional problems, and maintains a high level of player's willingness to play games even when the player has shifted to a gaming state where the player's advantage is low, such as a low-probability RT state. It is intended to provide a slot machine that can do this.

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 pull-in 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 it is determined by the winning determining means that a winning has occurred;
When the combination of symbols stopped and displayed in the symbol display area in the normal state is a combination of the first specific symbols, the first gaming state is generated over a predetermined first duration, and the first duration is First game state generating means for returning to a 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 a combination of second specific symbols, a second gaming state having a higher degree of advantage on the player side than the first gaming state is generated, A second gaming state generating means for returning to the normal state when the combination of the third specific symbols is stopped and displayed in the symbol display area in the second gaming state;
First notification means capable of notifying a player of first avoidance information for avoiding a stop display of the first specific symbol in a normal state;
Second informing means capable of informing the second avoidance information for avoiding the stop display of the third specific symbol in the second gaming state;
First AT activation lottery means for executing a first AT activation lottery during the occurrence of the first gaming state for determining whether or not to activate the first AT for which the first avoidance information is notified after returning to the normal state; ,
Second AT activation lottery means for executing a second AT activation lottery for determining whether or not to activate the second AT informed of the second avoidance information during the occurrence of the second gaming state;
When the first AT launch lottery is won during the occurrence of the first gaming state, the second AT launch lottery lottery is performed within the remaining first gaming period until the first gaming state ends and returns to the normal state. There is provided an AT condition lottery means for executing an AT activation condition lottery for determining a condition (claim 1).

  In the slot machine game of the present invention, the first AT activation lottery for determining whether or not to activate the first AT for which the first avoidance information is notified is executed while the first gaming state is occurring. If the first AT is activated after winning the first AT activation lottery and shifting to the normal state, the notification of the first avoidance information makes it possible to avoid the stop display of the first specific symbol with high certainty. Become. Therefore, in the game of the slot machine, even when the game is shifted to the disadvantageous first game state, the expectation for the first AT is expected as the first game state is digested and the shift to the normal state becomes closer. The feeling is gradually increased. If the first AT is activated after returning to the normal state, the transition to the first gaming state can be avoided, and the possibility of transition to the second gaming state is increased.

  After the transition to the second gaming state, the second AT activation lottery for determining whether to activate the second AT for which the second avoidance information is notified is executed. If the second AT is activated, the second gaming state can be continued for a long period by avoiding the stop display of the third specific symbol. The lottery condition for the second AT activation lottery is that the AT executed in the remaining first game period after winning the first AT activation lottery and returning to the normal state in accordance with the end of the first gaming state. It is determined by the lottery for activation conditions. Since the degree of advantage of the second AT trigger lottery varies according to the result of the AT trigger condition lottery, the player's sense of expectation and tension with respect to the second AT can be maintained high during the remaining first game period.

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.
As the second AT activation lottery, various lotteries such as a lottery for continuing or immediately ending the second AT and a lottery for determining whether to extend the duration of the second AT can be adopted. .

Further, in the AT activation condition lottery, the lottery object role that triggers the second AT activation lottery and the winning probability corresponding to the lottery object role are determined as the lottery condition,
The second AT invocation lottery means preferably executes the second AT invocation lottery with a winning probability corresponding to the lottery target when the lottery subject in the second gaming state wins a prize or is won internally ( Claim 2).
In this case, the player's sense of expectation with respect to the second AT can be enhanced each time the lottery target combination wins or is won internally.

In addition, as a candidate for the lottery condition of the second AT activation lottery, a plurality of types of candidate conditions having different degrees of advantage in which a combination of the lottery target combination and the winning probability is defined are set,
The AT condition lottery means sequentially switches candidate conditions to be selected as candidates for the lottery conditions from among the plurality of types of candidate conditions each time a predetermined condition is satisfied, and the remaining first game period It is preferable that the candidate condition selected at the end of the is determined as the lottery condition.

  In this case, every time the predetermined condition is satisfied within the remaining first game period or the possibility of establishment is generated, the player's expectation and tension can be given. As the predetermined condition, various conditions can be set, such as winning a lottery executed for each game, winning a predetermined combination or winning an internal prize. In addition, the last candidate condition of the rank is set most advantageously, and when the candidate condition is reached, the candidate condition is determined as the lottery condition even in the middle of the remaining first game period. Also good. Instead of this, as long as the establishment of the predetermined condition overlaps, it is also possible to enter the second round of the rank.

  The slot machine of the present invention can maintain a player's sense of expectation and tension and suppress a decrease in gaming motivation even when the player has transitioned to the first gaming state where the player's degree of advantage is low. It is a slot machine with excellent characteristics.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example relates to a slot machine 1 that can generate a low-probability RT state (first gaming state) with a low internal winning probability of a replay role and a high-probability RT state (second gaming state) with a high internal winning probability of a replay role. It 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. The front portion of the slot machine 1 is formed by a front frame 10 having a substantially rectangular symbol display window 11 provided at a substantially 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 shelf-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 is adjacent to the lower side of the operation surface 14. 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 disposed. 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 in response to direct insertion of medals or insertion of medals 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 is composed of five lines including upper, middle, and lower stages, three horizontal winning lines 211 to 213, and diagonal winning lines 214 and 215.

  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 for effecting a game.

Next, the role of the slot machine 1 of this example and the symbol arrangement on each reel 21 will be described.
In the slot machine 1 of this example, as shown in FIG. 3, in addition to a bonus combination (BB combination, RB combination), 15 types of combinations A and B, 10 types of combinations A and B, a replay combination A ~ E 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. As the profit, the profit under the non-bonus state shown on the left side of the “profit” column in the figure and the profit under the bonus state shown on the right side are shown.

  In this example, the winning symbol of the replay role A is a low probability RT symbol (a combination of the first specific symbols) that triggers the transition to the low probability RT state, and the winning symbol of the replay role C is in the high probability RT state. It is a highly reliable RT symbol (a combination of the second specific symbols) that becomes the transition opportunity of In addition, the 10-piece combination spilled symbol that is stopped when the 10-piece combination is missed is a high-definition RT end symbol (combination of the third specific symbol) that triggers the end of the high-precision RT state. Note that the replay combination A in the normal state and the ten-piece combination in the high-probability RT state are AT notification target combinations.

Here, the winning combination of the replay combination and the 10-sheet combination that are AT notification targets will be described. As shown in FIG. 3, 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 “black orange” based on the winning symbol of the replay role A, the winning symbol of the replay role B is obtained, and if the right reel 21R is replaced with the symbol “sun”, the winning symbol of the replay role C is Become.
Also, the winning symbol for the 10-piece combination A is a “black orange” doublet. The combination of the left reel 21L replaced with “white orange” based on the winning symbol of 10-piece combination A is the winning symbol of 10-piece combination B.

In each reel 21L, C, R, symbols are arranged as shown in FIG.
In the left reel 21L and the middle reel 21C, the maximum interval of the symbol “R” common to the replay roles A to C is 4 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. Further, as described above, in the symbol display areas 110L and 110C, a winning line is set over three symbols in the upper middle stage and the lower stage. Therefore, “R” in the left reel 21L and the middle reel 21C is always present within the pull-in range regardless of the timing of the stop operation, and has a symbol that can be stopped and displayed on the winning line.

  In the right reel 21R, the maximum interval is 4 symbols for the symbol “R”, the symbol “black orange”, and the symbol “sun” respectively corresponding to the replay roles A to C. Like the symbol “R” on the left reel 21L, “R”, “black orange”, and “sun” on the right reel 21R always exist within the draw-in range regardless of the timing of the stop operation, and are stopped on the winning line. It has become a design that can be made.

  The replay roles A to C in the slot machine 1 of the present example in which the symbols of the replay roles are arranged as described above always win if they are selected alone, and the stop button 61L even if they are simultaneously selected with other replay roles. If C, R are stopped in a predetermined order, it is a replay role that always wins a prize. In the slot machine 1, there is a first stop reel that is an operation mode of a stop button for winning the replay role C by avoiding the replay role A when the simultaneous winning including the replay role A and C occurs. Yes. The relationship between the first stop reel and the type of winning replay combination will be described later with reference to FIG.

  On the other hand, the symbols corresponding to the 10-piece combination are as follows. In the middle reel 21C and the right reel 21R, the maximum interval of the symbols “black orange” common to the 10-sheet combination A / B is 4 symbols. Therefore, “black orange” in the middle reel 21C and the right reel 21R is always present within 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 left reel 21L, the maximum interval of a specific type of symbol “orange” corresponding to one of the 10-piece combinations A and B is 13 or more symbols, and any type of symbol “ The maximum interval of “Orange” is 6 symbols. Therefore, one of the two types of “orange” in the left reel 21L can always be within the pull-in range regardless of the timing of the stop operation. On the other hand, a specific type of “orange” cannot be stopped unless the timing of the stop operation matches.
As for the 10-piece combination A / B in which the symbols are arranged in this way, one of the 10-piece combinations can always be won when winning simultaneously, while the winning probability when the type is unknown when winning alone is 1/2.

  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.

  The liquid crystal display unit 53 connected to the control unit 3 realizes functions as the first notification unit 71 and the second notification unit 72 in the normal state with AT and the high-accuracy RT state. The contents of the normal state screen 710 by the first notification unit 71 and the RT in-progress screen 720 by the second notification unit 72 will be described in detail later with reference to FIGS. 10 and 11.

  As shown in FIG. 5, the control unit 3 includes a CPU 31, a ROM 33 / RAM 34 as memory means, an I / O unit 32 as an input / output interface, and a random number extraction unit 35 for extracting random numbers for internal winning combination lottery. And a random number generator 350 for generating random numbers. 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 winning, first game state generating means 451 for generating a low probability RT state, and second for generating a high probability RT state A gaming state generating means 452, a first AT starting lottery means 461 for executing the first AT starting lottery during the occurrence of the low probability RT state, a second AT starting lottery means 462 for executing the second AT starting lottery during the occurrence of the high probability RT state; AT condition lottery means 47 for executing AT activation condition lottery, and AT activation means 4 for activating AT (first AT, second AT) Realizing the functions of as.

The storage area of the RAM 34 is provided with an AT counter 341 for storing the number of notifications by the AT in the highly accurate RT state.
The ROM 33 includes an internal winning combination lottery table (FIG. 6) used by the internal lottery means 41 for the internal winning combination lottery, a reel control table (not shown) used for the stop control of the reel 21 by the display control means 42, and a first AT activation lottery. For this purpose, an AT activation lottery table (FIG. 7), an AT continuous lottery table for second AT activation lottery (FIG. 8), and an AT continuation condition lottery table (not shown) for AT activation condition lottery are stored.

The reel control table is a data table in which stop positions that can be stopped on the winning line are 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 each combination other than the replay combination are common, but the winning random numbers of the replay combination are different. In the table for the normal state, only random numbers that are simultaneously won by two or more types of replay combinations including the replay combination A 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 C that is the trigger for the high-accuracy RT state is about 1/22. .

  In each table for the low probability RT state and the high probability RT state, only the random number that the replay combination A alone wins internally is set, and the difference is the internal winning probability of the replay combination A. While the internal winning probability of the replay combination A in the table for the low probability RT state is 1 / 7.3, the same probability in the table for the high probability RT state is 1 / 1.5.

  As shown in FIG. 7, the AT activation lottery table is a data table in which AT winning random numbers for winning the first AT activation lottery are defined. In this example, a part of the winning random numbers of the 15 and 10 winning combinations under the low probability RT state is an AT winning random number. For example, 100 out of 500 winning random numbers of 15 winning combinations A and 10 out of 3000 simultaneous winning random numbers of 10 winning combinations A and B are AT winning random numbers. In the entire random number range of 0 to 65535, 232 random numbers are AT winning random numbers.

  As shown in FIG. 8, the AT continuous lottery table is a data table in which a continuous winning random number for winning the second AT activation lottery is defined for each lottery condition. In the figure, the fields that do not correspond to the lottery object combination that triggers the second AT activation lottery are indicated by hatching. As can be seen from the figure, the combination of the lottery subject is different for each lottery condition. For example, the lottery target combination in the condition 1 is a 15-sheet combination A to C, and the 10-sheet combination and the replay combination are not applicable. Under condition 1, 25 of the 50 winning random numbers for the 15 combination B are continuous winning random numbers. When the conditions 1 to 3 are compared, the type of lottery object combination is the largest, and the condition 3 in which the occupancy ratio of the continuous winning random number among the winning random numbers of each lottery object combination is the most advantageous lottery condition. Since the continuous winning random number in condition 3 is 3,100, the winning probability is 3100 / 65536≈1 / 21.1.

  The AT continuation condition lottery table (not shown) is a data table in which a winning random number that advantageously switches the lottery conditions of the second AT activation lottery is defined. In the AT continuation condition lottery table of this example, 3300 out of the whole random number range of 0 to 65535 are winning random numbers.

  As shown in FIG. 5, the random number extraction unit 35 extracts a random number for internal winning combination lottery from random numbers (0 to 65535) generated by the random number generation unit 350. In this example, the first and second AT trigger lotteries, the AT trigger condition lottery, and the like are executed using a random number for internal winning combination lottery. Instead of this example, a dedicated random number for lottery may be applied to each lottery.

  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 (flag) corresponding to the internal winning combination. The internal lottery means 41 collates the random numbers for the internal winning combination 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 first AT activation lottery means 461 is a means for executing a first AT activation lottery for determining whether or not to activate the first AT after returning to the normal state. The first AT invocation lottery means 461 executes the first AT invocation lottery by comparing the internal winning combination lottery random number extracted in the game under the low probability RT state with the AT invocation lottery table (FIG. 7). When the first AT activation lottery is won, the first AT activation lottery is not executed within the remaining game period in the low-probability RT state. Further, when the first AT activation lottery is won, 5 is set as the counter value of the AT counter 341. As a result, the number of notifications by the second AT after the transition from the normal state to the high-accuracy RT state is fixed to 5 times.

  The AT condition lottery means 47 is a means for executing an AT activation condition lottery for determining a lottery condition for the second AT activation lottery under the high-accuracy RT state. The AT condition lottery means 47 continues the AT with random numbers for the internal winning combination lottery extracted in each game within the remaining game period (remaining first game period) in the low probability RT state after winning the first AT trigger lottery. The AT activation condition lottery is executed by collating with the condition lottery table. In this example, among the three types of candidate conditions with different degrees of advantage in conditions 1 to 3 (see FIG. 8), the candidate conditions that are advantageous one step each time the AT activation condition lottery is won starting from condition 1 Can be switched to. When the condition 3 is reached, the lottery condition is confirmed under the condition 3, and thereafter the AT activation condition lottery is not executed. When the condition 1 or the condition 2 is selected as the candidate condition and the normal state is restored, the candidate condition is determined as the lottery condition.

  The second AT activation lottery means 462 is a means for executing a second AT activation lottery for determining whether or not to extend the duration of the second AT being activated under the high-accuracy RT state. The second AT invocation lottery means 462 performs the second AT invocation lottery by comparing the winning random number at that time with the AT continuous lottery table (FIG. 8) when a predetermined lottery subject specified for each lottery condition is won internally. Execute. When the second AT activation lottery is won, the number of notifications stored in the AT counter 341 is added five times, and the duration of the AT under the high probability RT state is extended.

  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 corresponding 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. Further, for example, when 15 winning combinations are winning combinations, a benefit of paying out 15 medals is given. Note that the bonus state includes a BB state in which the trigger combination is a BB combination and ends in response to a payout exceeding 300 sheets, and an RB state in which the trigger role is an RB role and ends in response to a payout exceeding 100 sheets. is there. Further, in the bonus state, 15 medals are paid out in accordance with winnings of all the small roles (excluding the replay role) including 10 winning combinations.

  The first game state generating means 451 is a means for generating a low probability RT state that is disadvantageous to the player. The first gaming state generating means 451 generates the low probability RT state when the winning symbol of the replay combination A which is the low probability RT symbol is stopped and displayed under the normal state. The duration of the low probability RT state (first duration) is fixed to 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 second gaming state generating means 452 generates a high probability RT state when the winning symbol of the replay combination C, which is a high probability RT symbol, is stopped and displayed under the normal state. The second gaming state generating means 452 terminates the high probability RT state and returns to the normal state when the 10-piece winning symbol that is the high probability RT end symbol is stopped and displayed.

  The AT activation unit 48 is a unit that activates the AT during the occurrence of the normal state and the high-accuracy RT state. The AT activation means 48 activates the first AT in response to the return to the normal state when the first AT activation lottery is won in the low probability RT state. In the high-accuracy RT state, if the number of notifications stored in the AT counter 341 is 1 or more, the second AT is activated. The number of notifications by the second AT is subtracted once every time notification is executed, and the AT ends when the notification becomes zero. In addition, when the second AT trigger lottery executed under the high-accuracy RT state with AT is won, the number of notifications is added five times for each win, thereby extending the duration of the AT.

Here, with reference to FIG. 9, the distribution of the winning replay combination corresponding to the first stop reel when the simultaneous winning pattern of the replay combination occurs will be described.
For example, when the first stop reel is the left reel 21L or the middle reel 21C in the replay combination A / B / C simultaneous winning pattern, the replay combination A wins. On the other hand, when the first stop reel is the right reel 21R, the replay combination C wins. At this time, the fact that the right reel 21R should be the first stop reel is that the winning symbol of the replay role A, which is the low-definition RT symbol, is avoided by displaying the winning symbol of the replay role C, which is the high-definition RT symbol, being stopped. It becomes the 1st avoidance information for doing.

Next, the AT contents and AT screen executed by the first notification means 71 and the second notification means 72 will be described.
The first notification means 71 performs notification of first avoidance information for avoiding the replay combination A in response to simultaneous winning of the replay combination in the normal state with the AT. Specifically, the display of the normal state screen 710 in FIG. 10 notifies the first stop reel for avoiding the winning of the replay combination A whose winning symbol is the low probability RT symbol. The normal state screen 710 displays a first stop notification column 711 for notifying the first stop reel that avoids the replay combination A, and the difference number (the number of payouts−the number of inputs) since the start of the normal state with AT. It is an AT screen that combines a difference number display column 712 and a replay combination notification column 714 that notifies the type of a replay combination to be won according to notification.

  In particular, as illustrated in FIG. 10, in a game in which the winning symbol of the replay role C, which is a highly accurate RT symbol, can be stopped and displayed, the first avoidance information for avoiding the replay role A by winning the replay role C is displayed. Inform. This figure is a notification example that the first stop reel for winning the replay combination C is the middle reel 21C.

  The second notification means 72 performs notification of second avoidance information for avoiding missing in accordance with the single winning combination of the 10-sheet combination A and B in the high-accuracy RT state with AT. Specifically, the type of 10 winning combinations won internally is notified by the display of the during-RT screen 720 of FIG. The in-RT screen 720 includes a state notification column 724 for notifying that a highly probable RT state is occurring, an internal winning combination notification column 721 for notifying the types of the 10 winning combinations, and a normal state with AT. AT screen combining a difference number display field 722 for displaying a difference number (payout number-injection number) since the start, and a remaining notification number display field 723 for displaying a remaining notification number under a high-precision RT state It is. This figure is a screen during RT for notifying that the 10 winning combination A has won internally as the second avoidance information.

  On the other hand, in the high-accuracy RT state without AT, as in the RT screen 730 in FIG. 12, only the fact that 10 winning combinations are won internally is notified, and the type is not notified. The screen during RT 730 is the same as the screen during RT 720 except for the point that the type of the 10 winning combinations won in the internal winning combination notification column 731 is not specified.

  Further, when the first AT activation lottery is won during the occurrence of the low probability RT state, the AT activation means 48 displays an AT confirmation screen 740 on the liquid crystal display unit 53 as shown in FIG. The AT confirmation screen 740 includes a confirmation notification column 742 that indicates that the first AT activation lottery is won by the character string “AT”, and a remaining game number display column 741 that displays the remaining number of games in the low probability RT state. Arranged.

Next, the transition of the gaming state of the slot machine 1 configured as described above will be described with reference to the state transition diagram of FIG.
(Normal state)
The normal state is an initial state that occurs in response to the end of another gaming state including a bonus state. The normal state is terminated in response to the stop display of the high-accuracy RT symbol (replay role C winning symbol) or the low-accuracy RT symbol (replay role A winning symbol), and transition to the high-accuracy RT state and low-accuracy RT state. Will occur. Moreover, it ends also by winning of the BB combination or the RB combination, and shifts to the bonus state BB state or RB state. 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 because the winning probability of the replay role is as low as 1 / 7.3. When shifting to the low probability RT state, the first AT trigger lottery is executed for each game. When the first AT activation lottery is won, the AT confirmation screen 740 (FIG. 13) is displayed on the liquid crystal display unit 53, and thereafter the AT activation condition lottery is executed within the remaining game period until the normal state is restored.

(High accuracy RT state)
The high probability RT state is advantageous 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. When the normal state with AT shifts to the high-accuracy RT state, the AT is activated as it is. Under the high-accuracy RT state with AT, the second AT activation lottery based on the lottery conditions determined by the AT activation condition lottery is executed. If you win the 2nd AT launch lottery, the duration of AT will be extended.

  In the game of the slot machine 1 of the present example configured as described above, since the first AT activation lottery is executed in the low-probability RT state, the expectation for the first AT gradually increases as the return to the normal state approaches. In addition, when the first AT activation lottery is won and the first AT is confirmed, in the remaining low probability RT state, the lottery conditions for the second AT activation lottery executed after the transition to the high probability RT state are determined. AT activation condition lottery is executed. As the number of AT activation condition lottery wins increases, the more advantageous lottery conditions can be obtained. Therefore, whether the winning period of the first AT activation lottery is early or late in the generation period of the low-accuracy RT state is a major point.

  As described above, the slot machine 1 of the present example is excellent in that it is possible to suppress a decrease in the player's willingness to play even when the player has shifted to a gaming state where the player's advantage is low, such as a low-probability RT state. It is a slot machine with characteristics.

  In this example, after the transition to the low probability RT state, the first AT activation lottery is executed for each game. Alternatively, the first AT activation lottery may be executed every time a plurality of games are consumed. Further, the AT activation condition lottery executed after winning the first AT activation lottery may be executed every time a plurality of games are consumed.

  In this example, the lottery conditions for the second AT activation lottery determined under the low-accuracy RT state are not notified, but instead, when the low-accuracy RT state ends or the high-accuracy RT with AT is present. When transitioning to a state, it is also possible to notify the determined lottery conditions.

  This example is an example in which no AT is activated after returning to the normal state when the first AT activation lottery is not won in the low-probability RT state. Alternatively, the AT may be activated even when the first AT activation lottery is not won in the low probability RT state. For example, an AT activation lottery may be separately performed when the replay combination A is internally won in a normal state, and the AT may be activated when the winning is made.

Further, in this example, when the normal state without AT shifts to the high-accuracy RT state, the type of the 10 winning combinations won is not notified, but a case of notification may be set.
In this example, the number of notifications is set for the duration of the AT under the high-probability RT state, but the number of games can be set instead.

  In this example, three types of conditions are set as the lottery conditions for the second AT activation lottery. However, conditions different from this example may be set as the lottery conditions, or the number of types may be increased. Furthermore, in this example, the most advantageous lottery condition (condition 3 in FIG. 8) was determined when the AT activation condition lottery was won twice, but instead, in accordance with the third win, It can also be set to return to condition 1.

In this example, the winning symbol of the replay role A is set as the low-accuracy RT symbol, and the winning symbol of the replay role C is set as the high-accuracy RT symbol. Not only the winning symbol for the replay role, but any symbol combination may be used.
Note that the duration of the low probability RT state (first duration) can be set as appropriate. It is not limited to 64 games of this example.

Note that the second AT activation lottery in this example is a lottery for determining whether or not to continue the activated AT. Instead, when shifting from the normal state with AT to the high-accuracy RT state, the AT is stopped as it is, and the second AT is activated whether or not the AT is activated every time the 10-player combination is elected alone A lottery may be executed. In this case, the winning probability of the second AT activation lottery can be determined by the AT activation condition lottery. For example, if the lottery condition with a winning probability of 80% is determined, the second AT will be activated with a probability of 80% when the 10 winning combination is elected after the transition to the highly accurate RT state. Is likely to continue for a long time.
Further, it is also possible to execute an end lottery for determining whether or not to end the AT for each game while setting the number of AT games under the high probability RT state to unlimited.
