Description

  The present invention relates to a slot machine that gives a prize according to a combination of symbols displayed in a stopped state.

  Conventionally, for example, there is a slot machine that determines an internal winning combination by an internal lottery and gives a prize according to the determined internal winning combination. In such a slot machine, if there is a symbol of an internal winning combination within a predetermined pull-in range based on the occurrence time of the stop operation of the player who wants to stop the reel, the symbol is pulled in and the reel is stopped. Some implement so-called pull-in control.

  If the winning probability by the internal lottery of the slot machine is constant over the entire game period, the game becomes monotonous and may cause the player to get bored. Therefore, in many slot machines, in addition to the normal game state, an attempt is made to change the gameability by generating a special game state such as a bonus game in which the play rate is set higher than the normal game state. Yes. In a special game state such as a bonus game, for example, the winning rate is increased by setting the internal winning probability of a small role high.

  In addition to the first bonus game in which the player's possession (game media owned by the player) increases, the player's possession decreases in order to improve the interest by prominently changing the gameability. A slot machine that generates a second bonus game has also been proposed (see, for example, Patent Document 1). According to this slot machine, by executing the second bonus game in which the player's possession decreases, the output rate of the first bonus game is suppressed while suppressing the change in the output rate throughout the game period. It is possible to increase euphoria.

  However, the conventional slot machine has the following problems. That is, as described above, the second bonus game in which the player's ball is reduced is likely to be painful for the player, and there is a problem that the game may end.

  The present invention has been made in view of the above-described conventional problems, and it is possible to set a bonus game that is more disadvantageous to the player than in a normal gaming state, while avoiding the bonus game. It is intended to provide a slot machine that enhances the fun of.

The present invention comprises a plurality of symbol variation display means for variably displaying a plurality of types of symbols along a predetermined arrangement;
Plus bonus combination is an opportunity role of advantageous plus bonus games for the player than the normal game state, a plurality of minus bonus combination is an opportunity role of adverse negative bonus game for the player than the normal game state, and the player An internal lottery means for determining an internal winning combination by lottery from a plurality of roles including a plurality of specific small roles advantageous to the internal winning combination, and setting an internal winning flag indicating a state in which the internal winning combination can win
A symbol stop operation means operated by a player to stop the variation of the symbol by the symbol variation display means;
If there is a symbol corresponding to the internal winning flag within a predetermined pull-in range based on the operation time point of the symbol stop operation unit, the display control unit pulls the symbol onto the winning line and stops it.
Among the internal winning flags, the internal winning flag corresponding to the positive bonus combination is deleted when the positive bonus combination is won and won when the next game is won, while the positive bonus combination of the internal winning flags is deleted. An internal winning flag corresponding to a role other than the flag control means configured to be erased by the start of the next game regardless of whether or not the winning combination has been won,
The internal lottery means is configured such that one negative bonus combination of the plurality of negative bonus combinations and any specific small combination of the plurality of specific small combinations can be internally won simultaneously in one game. The symbol variation display means is always arranged in the predetermined arrangement in which at least any of the symbols of the minus bonus combination is included in the predetermined pull-in range regardless of the operation time of the symbol stop operation means. In the game where the minus bonus combination and the specified small role are simultaneously elected at the same time, winning of the minus bonus combination, winning of the specific small role, and loss without winning can occur. A configured slot machine,
Specific small role flag notifying means for notifying the internal winning flag of the specific small role,
A slot machine comprising a minus bonus flag notifying means for notifying the internal winning flag of the minus bonus combination (claim 1).

  In the slot machine of the present invention, the internal lottery means may cause an internal winning as the positive bonus combination that triggers the positive bonus game which is more advantageous to the player than the normal gaming state, and the normal game There is the minus bonus combination which is an opportunity for the minus bonus game which is disadvantageous to the player rather than the state. In the slot machine, the presence of the minus bonus game, which is disadvantageous to the player, can set a large advantage difference from the plus bonus game, and can further enhance the fun of the game by further changing the game characteristics. . In particular, for example, when there is a restriction on the player's advantage level throughout the game, the player's advantage in the plus bonus game is reduced due to the existence of the minus bonus game which is disadvantageous to the player. It can be set higher and can improve euphoria.

  Of the symbol variation display means of the slot machine, the predetermined arrangement of at least one of the symbol variation display means is such that, depending on the operation time of the symbol stop operation means, the symbol of the minus bonus combination is the predetermined symbol. It is configured not to be included in the pull-in range. Therefore, even in a game where the minus bonus combination is won internally, if the symbol stop operation means can be operated well so that the symbol of the minus bonus combination won internally is not included in the predetermined pull-in range, the minus It is possible to avoid winning a bonus combination.

  Then, the flag control means carries over the internal winning flag of the plus bonus combination until winning, and deletes the internal winning flag as it is when the negative bonus combination is not won in the internal winning game. . Therefore, if the winning can be avoided in the game in which the minus bonus combination is won internally, the internal winning flag can be deleted as it is.

  In the slot machine of the present invention, depending on the skill of the player, it is possible to play while avoiding the winning of the minus bonus combination. If the player can play while avoiding the winning of the minus bonus combination, only the benefits of the plus bonus game advantageous to the player can be enjoyed. The player will concentrate on the game so as to avoid winning the minus bonus combination. Then, when the player plays the game without winning the minus bonus combination and can win the plus bonus combination, he can feel a sense of accomplishment and can feel satisfaction with his skill level.

  As described above, the slot machine of the present invention is a gaming machine that uses the existence of the minus bonus game to enhance the interest of the game.

The slot machine according to the present invention may be a slot machine in a narrow sense using medals or coins as a game medium, or a parrot (R) using a pachinko ball as a game medium.
As a method of setting a disadvantage for the player by keeping the degree of advantage in the minus bonus game low, there is a method in which a winning combination including a plus bonus combination is not performed or the winning probability is reduced, or when a winning combination is won. There are various methods such as a method of setting the number of game media to be output low.

  “A gaming state that is more advantageous to the player than the normal gaming state” means a gaming state in which an expected value of the number of game media that can be acquired per game is larger than that in the normal gaming state. Further, “disadvantageous to the player than the normal gaming state” means a gaming state in which the expected value of the number of game media that can be acquired per game is smaller than that in the normal gaming state. Here, the expected value of the number of game media that can be acquired per game is a value obtained by subtracting the number of game media required for one game from the expected value of the number of game media paid out due to the result of the game. This represents an expected value of an increase in the number of game media owned by the player. Here, game media to be paid out due to game results include game media to be paid out in a bonus game triggered by winning of a bonus combination, and game media to be paid out by winning a combination other than the bonus combination. Therefore, the expected value of the number of game media that can be acquired per game is the game value that is paid out by the expected value of the number of game media to be paid out in the bonus game triggered by the winning of the bonus combination and the winning of the combination other than the bonus combination. This is a value obtained by subtracting the number of game media necessary for one game from the sum of the expected number of media.

  For example, in the case of a slot machine that generates a bonus game that requires the insertion of 96 (3 × 32 games) game media while 480 (15 × 32 games) game media are paid out, per game The expected value of the number of game media that can be obtained is calculated as follows. For example, the internal winning probabilities of three types of 15-card combinations in the normal gaming state are each 1/10, and the stop operation timing for stopping and displaying the three types of 15-card combinations is substantially different. If the winning probability is 1/3 each, the expected value of the number of game media to be paid out in response to the three types of 15 winning combinations is 15 × 1/10 × 1/3 × 3 (type) = 1.5 sheets. Further, if the winning probability of the bonus combination in the normal gaming state is 1/250, the expected value of the number of game media to be paid out when the bonus combination is won is (480-96) × (1/250 ) = 1.536 sheets. Therefore, the expected value of the number of game media that can be acquired per game is 1.5 + 1.536-3 (the number of inserted games per game) = 0.036.

The internal lottery means is preferably configured not to determine the internal winning combination of the plus bonus combination by lottery in the minus bonus game (claim 2).
In this case, there is no possibility of internal winning of the plus bonus combination in the minus bonus game. Thereby, the player's degree of advantage in the minus bonus game can be effectively suppressed.

Further, a minus bonus flag notifying means for notifying an internal winning flag of the minus bonus combination is provided .
In this case, a player who knows that the negative bonus combination has been won internally through the negative bonus flag notification means plays a more concentrated game so that the negative bonus combination is not won in the game. It becomes like this. When the winning of the minus bonus combination can be avoided, the player can feel a sense of accomplishment and satisfaction. On the other hand, the minus bonus flag notifying means also implements a state in which the minus bonus combination is not notified internally, so that the minus bonus combination is always concentrated and played so as not to win the minus bonus combination. Motivate players.

  Note that the game in which the minus bonus flag notifying means notifies the internal winning of the minus bonus combination may be part or all of the game executed by the slot machine. Further, a special gaming state such as an assist time may be set, and when the minus bonus combination is won internally in this gaming state, it is also possible to notify that fact. Furthermore, it is possible to notify all internal winnings of the above-mentioned minus bonus combination during the occurrence of the assist time or the like, but it is also possible to notify only some of the internal winnings.

Further, the internal lottery means is configured so that the minus bonus combination and the specified small combination can be won simultaneously in one game, and the symbol variation display unit is configured to display the minus bonus combination and the specific small combination. In a game in which a winning combination is won at the same time, the winning of the minus bonus winning combination, the winning of the specific small winning combination, and the loss without winning can be generated .

  In this case, it becomes possible to avoid winning of the minus bonus combination by a more aggressive attacking game in which the specific small combination is won. Therefore, when winning the specified small role, there is a joy of winning the specified small role, and a satisfaction that the winning of the minus bonus role that may have been won at the same time is avoided. You can taste it heavily.

Further, a specific small combination flag notifying means for notifying the internal winning flag of the specific small combination is provided .
In this case, a player who knows that the specific small role has been internally won through the specific small role flag notification means causes the specific small role to be won in the game, thereby winning the minus bonus role. In some cases, it can be avoided. On the other hand, since the specific small combination flag notifying means also implements a state in which the specific small combination is not notified of the internal winning, the player always concentrates and plays the game so as not to win the minus bonus combination. . By actively aiming for the winning of the specific small role, the possibility of avoiding the winning of the negative bonus role is increased.

The game in which the specific small combination flag notification means notifies the internal winning of the specific small combination can be set in the same manner as the minus bonus flag notification means.
Further, when both the minus bonus flag notifying unit and the specific small role flag notifying unit are provided, the winning of the minus bonus combination can be further ensured by notifying the internal winning flag by each flag notifying unit. High avoidance will be possible.

In addition, a plurality of the minus bonus combinations are set, and the predetermined arrangement of the symbol variation display means always includes at least one of the minus bonus combinations regardless of the operation time of the symbol stop operation means. The symbol is configured to be included in the predetermined pull-in range .
In this case, there is no operation method of the symbol stop operation means for reliably avoiding winning of all the negative bonus combinations. The player needs to play the game with intuition so that none of the plurality of minus bonus combinations is won. Therefore, the sense of accomplishment and satisfaction when playing the game while avoiding the winning of the minus bonus combination will be even greater.
Further, it is preferable that the minus bonus game generated in response to the winning of the minus bonus combination is a gaming state that ends when the result of one game is obtained (claim 3 ). Here, the case where one game is obtained means a situation where the game is finished once, the game is finished, and the result of the game is obtained, that is, the game is finished.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example is an example of the slot machine 1 that generates a minus bonus game that is more disadvantageous to the player than the normal gaming state. The contents will be described with reference to FIGS.
As shown in FIGS. 1 to 3, the slot machine 1 of this example includes three symbol variation display means 2 (hereinafter referred to as a reel 2) that variably displays a plurality of types of symbols 20 along a predetermined arrangement. Internal winning roles including a plus bonus role that is an opportunity for a plus bonus game that is advantageous to the player over the normal gaming state and a negative bonus role that is an opportunity for a minus bonus game that is disadvantageous for the player than the normal gaming state An internal lottery means 42 that sets an internal winning flag that represents a state in which the internal winning combination can be won, and a symbol stop operating means 61 that a player operates to stop the fluctuation of the symbol 20 due to the reel 2. (Hereinafter referred to as the stop button 61) and a diagram corresponding to the internal winning flag within a predetermined pull-in range based on the operation time of the stop button 61. If there is 20, the display control means 45 that draws the symbol on the winning line and stops it, and the internal winning flag corresponding to the plus bonus combination among the internal winning flags, goes to the next game until the plus bonus combination wins. On the other hand, it will be deleted when the winning is carried over, while the internal winning flag corresponding to a role other than the plus bonus combination will be deleted before the next game starts regardless of whether or not the winning combination is won. Flag control means 41 configured as described above.
The predetermined arrangement of at least one of the three reels 2L, C, and R in the slot machine 1 of the present example does not include a symbol of a minus bonus combination within the predetermined pull-in range. The operation point of the stop button 61 can be present.
This content will be described in detail below.

  First, the combination of the slot machine 1, the internal winning combination, and the winning combination will be described with reference to FIGS. In this example, a BIG bonus combination (BB combination) is set as the plus bonus combination, and a BIG bonus game (BB game) is set as the plus bonus game. A single bonus combination (SB combination) is set as the minus bonus combination, and a single bonus game (SB game) is set as the minus bonus game. In the slot machine 1 of this example, in addition to the BB combination and the replay combination that enables replay, three types of SB combination, three types of 15-sheet combination and two-sheet combination are set. The SB game, which is a minus bonus game, is a game in which only one game is generated in response to the winning of the SB role, and the winning combination is drawn with a lottery probability different from the normal gaming state.

  In FIG. 3, the name of each combination is shown in the left column, the combination of each symbol 20 is shown in the middle column, and the medal payout number or privilege to be paid out as a prize is shown in the right column. In the slot machine 1, an internal winning combination by the internal lottery means 42 becomes an internal winning combination. And the symbol 20 which comprises this internal winning combination is a symbol. In the slot machine 1 of the present example, 15 winning combinations are set as specific small combinations that can be won simultaneously with the SB winning combination.

  As shown in FIG. 3, the combination of symbols in the middle reel 2C and the right reel 2R is the same for both the SB combination and the 15-sheet combination "white apple"-"white apple", and only the symbol of the left reel 2L Is different. The symbols of the left reel 2L of the first to third SB roles are “white apple”, “hatched apple”, and “black apple” in order. In addition, the symbols of the left reel 2L of the first to third 15-piece roles are “white 7”, “hatched 7”, and “black 7” in order.

  Thus, in the slot machine 1 of this example, the symbol that stops at the left reel 2L upon winning is the most important factor. As will be described in detail later, the slot machine 1 of this example is a gaming machine that has enhanced the fun of the game based on the combination of the pull-in control of the display control means 45, the setting of the symbol, the symbol arrangement on the reel 2, etc. It is.

  The slot machine 1 has a game specification in which a BB game is generated in response to the winning of the BB role, and after the BB game ends, an assist time (AT) for 100 games is executed. This assist time is a gaming state in which an internal winning flag of 15 winning combinations is notified. In this example, the time when the number of paid-out medals reaches 480 is set as the end of the BB game. In addition, the number of bets (the number of inserted medals) in the BB game is 3, and a maximum of 15 medals can be paid out per game. Therefore, the BB game of this example requires a minimum of 32 games, and the total number of medals required for the BB game is 96.

  Next, the slot machine 1 of this example has an external configuration as shown in FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 is provided with a liquid crystal display unit 53, a speaker 520, and a lamp unit 550 on the upper side in the vertical direction of the symbol display window 11. The speaker 520 and the lamp unit 550 are arranged so as to be symmetrical with respect to the liquid crystal display unit 53.

  As shown in FIG. 2, the front frame 10 has a base 100 that forms the base of the slot machine 1 on the lower side in the vertical direction of the symbol display window 11. Furthermore, on the right side of the symbol display window 11, a payout number display unit 540 for displaying the number of paid out medals and a credit number display unit 430 for displaying credits stored in a credit means (not shown) are arranged.

  As shown in FIG. 2, the base portion 100 is formed so as to protrude relatively with respect to the symbol display window 11 that is 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 a space between the operation surface 14 and the medal tray 15. An operation panel 13 is provided.

  As shown in FIGS. 1 and 2, the operation surface 14 has a bet button 64 for betting (betting) a medal credited by a credit means (not shown) and a settlement for paying out and paying out the credit medal. A button 65 and a medal insertion slot 630 for inserting a medal to bet on the game are arranged. The operation panel 13 is provided with a start lever 62 for starting the symbol variation of the reel 2 and a stop button 61 for stopping the symbol variation.

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

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

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

  As shown in FIG. 2, the symbol display window 11 is configured to display nine symbols 20 arranged in a two-dimensional matrix of three rows and three columns. The portion corresponding to the symbol display window 11 in the front frame 10 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. For the nine symbols 20 in the above two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of symbols to be awarded are set. As the winning lines, there are a horizontal winning line 211, a middle winning line 212, a lower winning line 213, and diagonal winning lines 214 and 215.

  As shown in FIGS. 1, 2, and 4, the reel 2 includes a left reel 2L, a middle reel 2C, and a right reel 2R. Each of the reels 2L, C, and R is a rotary reel having a substantially cylindrical shape and 21 symbols 20 selected from a total of eight types arranged at a substantially constant interval on the outer peripheral surface thereof. Each reel 2L, C, R has a reference position piece (not shown) at one reference position in the rotation direction. The reference position piece is a member as a detected piece detected by a reference position detection unit 66 described later.

  As shown in FIGS. 1, 2, and 4, the left reel 2L forms one column at the left end in a three-row × three-column two-dimensional matrix displayed in the symbol display window 11. The right reel 2R forms one row at the right end in the two-dimensional matrix. The middle reel 2C forms a central row in the two-dimensional matrix. The reel 2 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example. The structural features of the symbol arrangement of each reel 2L, C, R will be described later.

  The liquid crystal display unit 53 includes a liquid crystal display as shown in FIGS. The liquid crystal display unit 53 is configured to display various effect screens that produce games. In particular, the liquid crystal display unit 53 during the generation of the assist time uses a later-described notification pattern 531 (see FIG. 5) or notification pattern 532 (see FIG. 6) for notifying the internal winning of the 15-member combination that is the specific small combination. indicate.

Next, the slot machine 1 of this example has a mechanical configuration as shown in FIG.
A control board 3 that controls the overall operation of the slot machine 1 and each part that is electrically connected to the control board 3 will be described with reference to FIGS. 1 and 2. For the control board 3, in addition to the above configuration, a inserted medal detection unit 63 that detects a medal inserted as a game medium, a reel drive unit 51 that rotationally drives the reel 2, and a rotational position of the reel 2 are detected. A reference position detecting unit 66 for performing the game, a medal paying unit 54 for paying out medals, various display units 55 for producing a game, a set value operating unit 68 for setting a set value representing the player's advantage, and a speaker. An audio output unit 52 that controls 520 is electrically connected.

  As shown in FIGS. 1 and 2, the inserted medal detection unit 63 is configured to output an insert signal each time a medal is inserted from the medal insertion slot 630. Three insert signals correspond to the 3-bet signal. In the slot machine 1 of this example, which is a 3-bet dedicated machine, the start lever 62 is in an effective state when the number of bets for the game becomes 3 in response to reception of 3 insert signals or 3 bet signals. Set to

  As shown in FIG. 1, the reel drive unit 51 includes a stepping motor (not shown) that can be controlled in units of steps, and is configured to rotationally drive the reel 2 by the rotational driving force of the stepping motor. The stepping motor rotates by one step for each control pulse fetched from the control board 3.

As shown in FIG. 1, the reference position detection unit 66 is configured to detect the passage of the reference position piece of each reel 2L, C, R and output a detection signal.
As shown in FIG. 1, the medal payout unit 54 is configured to pay out a predetermined number of medals to the medal tray 15 under the control of the control board 3.
As shown in FIG. 1, the set value operation unit 68 uses a set key 680 to change the set value for setting the bonus winning combination probability to 6 levels.

  As shown in FIGS. 1 and 2, the control board 3 includes a CPU 31, a ROM 33 and a RAM 34 as memory means, and an I / O unit 32 as an input / output interface. The CPU 31 executes a software program read from the ROM 33 to extract a random number extracting means 48 for extracting random numbers, a winning combination determining means 49 for determining a winning combination, a display control means 45 for controlling the reel 2, and an internal winning combination. The internal lottery means 42 for controlling, the flag control means 41 for controlling the internal winning flag, the specific small combination flag notifying means 44 for notifying the internal winning flag of the 15-piece combination which is the specific small combination, and switching the gaming state generated by the slot machine 1 The game state switching means 46 is configured to realize each function.

  As shown in FIGS. 1 and 7 to 9, the ROM 33 as the memory means stores a winning random number table used by the internal lottery means 42 for the lottery of the internal winning combination. As shown in FIGS. 7 to 9, the winning random number table defines the winning random numbers for each winning combination. FIG. 7 is a normal winning random number table applied to the normal gaming state. FIG. 8 is a BB winning random number table applied to the BB game. FIG. 9 is an SB winning random number table applied to the SB game. 7 to 9 are diagrams in which random numbers are defined in the horizontal axis direction and roles are arranged in the vertical direction. The fractional value in the figure indicates the probability that each winning combination is won internally.

  As is known from FIG. 7, in the normal winning random number table of this example, the first, second, and third 15-sheet winning combinations are included so as to include the winning random numbers of the first, second, or third SB winning combinations, respectively. The winning random number is specified. Therefore, in the slot machine 1 of this example, when the first, second, or third SB combination is won internally, the first, second, and third 15-sheet combinations can be won simultaneously. Further, as is known from FIG. 8, in the BB winning random number table, winning random numbers from 0 to 65535 corresponding to the entire random number range are defined for the first to third 15 winning combinations. Therefore, in the BB game, three types of 15-card combinations can be won internally in all games. Further, as is known from FIG. 9, the SB winning random number table does not define the winning random number for the BB role. Therefore, in the SB game, the internal winning probability of the BB combination is set to zero%.

  The expected value of the number of game media that can be acquired per game in the normal gaming state (the number of acquired medals) is about zero based on the calculation method shown in “Means for Solving the Problems” in this specification. Become. The expected value of the number of medals per game in the BB game is 12 by the same calculation method, which is a game advantageous to the player. Furthermore, the expected value of the number of medals per game in the SB game is about minus 1.6 by the same calculation method, which is a disadvantageous game for the player as compared to the normal gaming state.

  As shown in FIGS. 1 and 2, the random number extracting means 48 is a means for extracting random numbers for lottery by an internal calculation of the CPU 31. The random number extraction means 48 of this example extracts a random number using the change start signal of the start lever 62 as a trigger signal and inputs it to the internal lottery means 42. In addition, the random number extraction means 48 of this example extracts an integer belonging to the range of 0 to 65535 as a random number for collation with the winning random number table.

  As shown in FIG. 1, the internal lottery means 42 collates the random numbers extracted by the random number extracting means 48 with winning random numbers such as winning random number tables shown in FIGS. This is means for setting the internal winning flag corresponding to the winning combination to ON. As shown in FIG. 3, the internal winning combination that the internal lottery means 42 of this example draws is BB combination, first to third SB combination, first to third 15 combination, two combination combination and replay combination. Nine types of roles.

  The flag control means 41 is a means for controlling an internal winning flag representing a state where each winning combination can be won as shown in FIG. The flag control means 41 of this example, for the internal winning flags other than the BB winning combination such as the SB winning combination and the 15-sheet winning combination, the next game is played regardless of whether or not the winning is made in the game in which the internal winning flag is set for the first time. Switch off before starting.

  On the other hand, the flag control means 41 of this example carries over the internal winning flag of the BB combination (hereinafter referred to as BB flag) to the next game until winning, and switches it off according to the BB combination winning. By the control of the flag control means 41 as described above, the SB combination and 15-sheet combination that have not won a prize in the internally won game are so-called missed. On the other hand, once the BB combination is won internally, the bonus confirmed state is maintained until winning.

  The gaming state switching means 46 is means for selectively generating various gaming states as shown in FIG. The gaming state generated by the gaming state switching means 46 includes a BB game triggered by a winning combination of BB, an SB game triggered by winning a winning combination of SB, and an assist time for notifying an internal winning flag of 15 winning combinations.

  The game state switching means 46 sets a state flag corresponding to each of the above game states. The gaming state switching means 46 generates a gaming state corresponding to the on state (1) state flag. The status flag includes a BB game flag corresponding to the BB game, an SB game flag corresponding to the SB game, an AT flag corresponding to the assist time, and the like.

  The BB game flag is a state flag that is set to an on state (1) in accordance with the winning of the BB combination and is set to an off state (0) when the number of medals paid out during the BB game reaches 480. . The SB game flag is a state flag that is set to the on state (1) for only one game in accordance with the winning of the SB combination. The AT flag is a state flag that is set to the on state (1) for 100 games after the end of the BB game.

  As shown in FIG. 1, the game state switching unit 46 applies the BB winning random number table (see FIG. 8) to the internal lottery unit 42 when the BB game flag is on. When the SB game flag is on, the SB winning random number table (see FIG. 9) is applied to the internal lottery means 42. When both the BB game flag and the SB game flag are off, the normal winning random number table (see FIG. 7) is applied to the internal lottery means 42. The game state switching means 46 generates an assist time when the AT flag is in the on state (1).

  As shown in FIGS. 1 and 2, the specific small combination flag notification means 44 is a means for notifying that 15 winning combinations have been internally won during the implementation period of the assist time. The specific small combination flag notification means 44 of this example displays the notification pattern 531 or the notification pattern 532 on the liquid crystal display unit 53 as shown in FIGS. 5 and 6 as two types of patterns for reporting the internal winning 15-piece combination. To do.

  As shown in FIG. 5, the notification pattern 531, for example, displays the symbol for the left reel 2 </ b> L such as “Aim at (No. 14) 7”, so that the second 15-piece combination is won internally. This is a pattern for informing the effect. As shown in FIG. 6, the notification pattern 532 displays “Hatching 7”-“white apple”-“white apple” and the winning symbol of the internal winning combination to indicate that the second 15-piece combination has been won internally. Is a pattern for informing the user. In a game in which 15 winning combinations are won internally at the assist time, the flag may be notified, or the flag may be notified by lottery with a probability of 1/2 or the like.

  The winning combination determining means 49 is a means for determining a winning combination based on the combination of symbols 20 stopped and displayed in the symbol display window 11 after all reels 2 are stopped, as shown in FIGS. The winning combination determining means 49 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 and determines whether or not a winning combination is established for the combination of the symbols 20.

  The display control means 45 is a means for controlling the symbol variation of the reels 2L, 2C, 2R via the reel drive unit 51 as shown in FIGS. The display control means 45 starts the symbol variation of the reel 2 in response to the variation start signal and stops the symbol variation of the reel 2 in response to the variation stop signal. The display control means 45 inputs a control pulse to the stepping motor that forms the reel driving unit 51, and rotates the stepping motor by one step for each pulse. The display control unit 45 counts the number of control pulses input to the reel driving unit 51, that is, the number of steps rotated by the stepping motor. In particular, in this example, the number of steps generated after the most recent detection signal is counted by resetting the number of steps to zero each time the detection signal of the reference position piece is captured.

  As shown in FIG. 1, the display control means 45 performs so-called pull-in control for stopping symbols within a predetermined pull-in range determined by rules (rules for game machine certification, type verification, etc.) on the winning line. Is configured to do. The display control means 45 can calculate the symbol (the symbol located on the winning line) currently displayed on each reel 2L, C, R and the subsequent symbol based on the number of steps. The display control means 45 calculates the symbol 20 instantaneously located within the drawing range of less than one frame from the winning lines 211 to 215 on the basis of the number of steps at the time when the fluctuation stop signal is fetched. The four symbols 20 following the head are set as symbols within the predetermined pull-in range.

  The pull-in control performed by the display control means 45 is a control in which if there is a symbol corresponding to the internal winning flag within the predetermined pull-in range, the symbol is drawn onto the winning line and stopped. On the other hand, in the pull-in control, when there is no symbol corresponding to the internal winning flag within the predetermined range, the lost symbol is drawn onto the winning line and stopped.

  Next, stop control of the reel 2 in the slot machine 1 of this example will be described in detail. The stop control of this example is a combination of the pull-in control by the display control means 45 as described above, the symbol arrangement as shown in FIG. 4 of each reel 2L, C, R, and the setting of the role symbol as shown in FIG. It is realized by.

  First, in the slot machine 1 of the present example, the role symbol of two sheets is set only to the symbol “cherry” of the left reel 2L as shown in FIG. The double winning combination has an internal winning probability set as low as 1/150 (SB game) or 1/200 (normal game state, BB game). On the other hand, the gap between the three symbols “cherry” in the left reel 2L is set to 7 symbols each. In the slot machine 1 in which the display width of the symbol display window 11 is set to 3 symbols, the number of symbols drawn by the display control means 45 is less than 4 symbols, which is the above-mentioned drawing range, in order to avoid winning of two winning combinations that are not won internally. Regulated by

  Further, in the slot machine 1 of this example, the symbols of the middle reel 2C and the right reel 2R are set in common to “white apple”-“white apple” for the SB combination and the 15-sheet combination. On the other hand, in the middle reel 2C and the right reel 2R, as shown in FIG. 4, the gap between the adjacent symbols “white apples” is set within 4 symbols. Therefore, in the slot machine 1, when either the SB combination or the 15-sheet combination is won internally, the symbol “white apple” is always drawn and stopped in the middle reel 2C and the right reel 2R.

  Here, using the case where the second SB combination and the second 15-sheet combination are won simultaneously according to the random numbers for lottery of 6232 to 9081, using FIG. 4, FIG. 7, and FIG. The details of the pull-in control by the display control means 45 will be described. FIG. 10 is a stop table for each reel 2L, C, R. For example, when the stop button 61L is operated when the symbol numbers 3 to 6 of the left reel 2L are located in the middle of the symbol display window 11 (FIG. 2), the symbol “R” of symbol number 6 is displayed. Indicates that it is pulled into the middle stage and stops.

  In the pull-in control of the left reel 2L, various symbols can be stopped according to the operation point of the stop button 61 as shown in FIGS. If the stop button 61 is operated when the symbols No. 21, No. 1, and No. 2 are located in the middle, the symbol No. 1 and No. 3 of “Hatching” are avoided while avoiding the symbol No. 4 “Cherry”. “R” of symbol number 2 stops in the middle so that “apple” is displayed. If “R” of symbol number 2 on the left reel 2L stops, the possibility of winning the second 15-piece combination disappears, while the possibility of winning the second SB combination remains.

  When the stop button 61 is operated when the symbols No. 3 to No. 6 are located in the middle stage, the symbol “No. 3” “cherry” is pulled in until it passes, and the symbol No. 6 “R” is in the middle stage. Stop. If the stop button 61 is operated when the symbol number 7 or 8 is located in the middle stage, the symbol number “R” stops at the middle stage. When the symbol number 6 or 8 stops, both the second SB combination and the second 15-piece combination winning possibility disappear.

  When the symbol number 9 to 13 is positioned in the middle stage, if the stop button 61 is operated, the symbol number 13 “R” stops in the middle stage so that the symbol number 14 “hatch 7” can be displayed. . If the stop button 61 is operated when the symbol number 14 or 15 is located in the middle stage, the symbol number 15 “black apple” is displayed in the middle stage so that “hatch 7” can be displayed. To stop. When “R” of symbol number 13 or “black apple” of symbol number 15 stops, the possibility of winning the second SB role disappears, and the possibility of winning the second 15-card role remains.

  When the stop button 61 is operated when the symbols of symbol numbers 16 to 20 are located in the middle, the symbol “cherry” of symbol number 18 is avoided and the “hatching apple” of symbol number 20 is displayed. Symbol number “R” stops in the middle. When “R” of symbol number 20 stops, the possibility of winning the second 15-sheet combination disappears, and the possibility of winning the second SB combination remains.

  In the left reel 2L of this example, the symbol of the second SB role is compared to the seven symbols of the four symbols that are the drawing range of the display control means 45 and the three symbols that are the display width of the symbol display window 11 in total. The gap of a certain “hatched apple” is set to a maximum of 15 symbols. Specifically, on the left reel 2L, the “hatched apples” of symbol number 3 and symbol number 19 are adjacent to each other with 15 symbols in between. In the left reel 2L, if the stop button 61 is operated when the symbols of symbol numbers 5 to 13 are located in the middle stage of the symbol display window 11 (winning line 212 in FIG. 2), the upper part of the symbol display window 11 ( The “hatched apples” are not included in any drawing range based on the winning line 211), the middle stage, and the lower stage (winning line 213).

  On the other hand, in this example, the second 15 sheets that can be won simultaneously with the second SB role in the symbol number 14 located in the largest gap (symbol number 4 to symbol number 18) of the "hatching apple". The symbol “Hatch 7” is placed. Therefore, in the slot machine 1 of this example, in accordance with the simultaneous winning of the second SB combination and the second 15-sheet combination, the second SB combination winning, the second 15-sheet winning, and the winning Loss of nothing can occur selectively.

  In the left reel 2L of this example, the “white apple” which is the symbol of the first SB role and the “black apple” of the third SB role are also “hatching apples” of the second SB role. Almost the same arrangement. Furthermore, as with the relationship between the symbol of the second SB role and the symbol of the second 15-sheet role, the first SB role can be simultaneously won in the largest gap of the “white apple” of the first SB role. The first 15-player “white 7” is arranged, and the third SB “black apple” is placed in the largest gap between the first 15-player and the third SB. Black 7 "is arranged. As described above, in the left reel 2L of this example, the relationship between the first SB combination and the first 15-sheet combination and the relationship between the third SB combination and the third 15-sheet combination are also described above. This is set in the same manner as the relationship between the SB combination and the second 15-sheet combination.

  Further, in the left reel 2L, symbols are arranged so that there is no operation point of the stop button 61L that can avoid winning of symbols of all SB roles. Specifically, the symbols of the left reel 2L are arranged so that the other two types of symbols of the SB role are arranged in the maximum gap between the symbols of each SB role. Therefore, in the slot machine 1 of the present example, no matter what timing the stop button 61L is operated, one of the SB combination symbols is always included in the predetermined pull-in range.

  On the other hand, in the middle reel 2C and the right reel 2R of the slot machine 1, as shown in FIGS. 4, 7, and 10, the gap between adjacent symbols “white apples” is set to a maximum of 4 symbols. Therefore, if the second SB combination and the second 15-sheet combination are won at the same time, and the left reel 2L is stopped, the winning possibility of any combination remains, the middle reel On the winning line in 2C and the right reel 2R, the “white apple” that is a common symbol for the second SB combination and the second 15-sheet combination can be stopped.

Next, the operation of the slot machine 1 of this example configured as described above will be described with reference to the flowchart of FIG. FIG. 11 is a flowchart showing the flow of the normal game process.
Here, first, as in step S101, it is determined whether or not the start lever 62 has been operated. When the start lever 62 is operated, an internal lottery process P1 for determining an internal winning combination by lottery is performed.

  Then, as in step S102, the flag state of the AT flag is determined. When the AT flag is in the on state (1), as shown in step S103, if there are 15 winning combinations for which the internal winning flag is established, the notification pattern 531 or 532 is displayed on the liquid crystal display unit 53, and the internal winning is achieved. The notification is implemented. On the other hand, if the AT flag is in the off state (0), step S103 is bypassed and the internal winning flag is not notified.

  In step S104, the rotation of the reel 2 is started. Thereafter, the process of performing the corresponding reel 2 stop process P2 in accordance with the operation of the stop button 61 as in step S105 is repeatedly performed until all the reels 2 are stopped. When all reels are stopped (step S106), the display of the notification patterns 531 and 532 is ended as in step S107 to end the notification of the internal winning flag, and the winning symbol is established on the winning line as in step S108. Judge whether or not. If a winning symbol is established, a winning process P3 is performed.

  As described above, in the slot machine 1 of the present example, the BB game is more advantageous by setting the SB game which is more disadvantageous to the player than the normal gaming state, and the interest of the game is enhanced. In this slot machine 1, in order to avoid winning the SB role in a game in which the SB role and the 15-card role are won at the same time, the symbol arrangement of the left reel 2L can be aimed at aiming for the 15-sheet winning or winning loss. Is devised. The player can concentrate on playing while avoiding winning of the SB role, and can always play with a sense of tension.

In this example, the reel 2 is stopped in the order of the left reel 2L → the middle reel 2C → the right reel 2R, so-called forward pressing is assumed. However, the order of the stop operation of the reel 2 is not limited to forward pressing. .
In addition, as a gaming state generated by the slot machine 1 of this example, a replay time (RT) in which the internal winning probability of the replay role is increased, or a challenge that can be aimed at winning a small role etc. regardless of the internal winning role. Time (CT) or the like can also be set. Furthermore, the assist time of this example can be generated simultaneously with the replay time.

Furthermore, when another bonus game is set in addition to the BB game, it is also possible to change and set the duration of assist time generated after the end of each bonus game.
Furthermore, in this example, the slot machine 1 is configured to generate an assist time after the end of the BB game. Instead, an assist time is generated in response to the establishment of a specific symbol, or a lottery is performed to determine whether an assist time is generated when a predetermined condition is met. Or, the assist time can be generated only for one game during the normal gaming state.

The combination for flag notification in the assist time is not limited to the 15 combination in this example, and other combinations can be set. The combination for notifying the flag is preferably a combination that can avoid winning the SB combination.
Further, in the assist time of this example, the flag is notified using the liquid crystal display unit 53, but the flag may be notified by sound using the speaker 520 instead.
Furthermore, although flag notification may be performed in the normal gaming state, it is preferable to set the notification level low for differentiation from the assist time.

In this example, three types of SB combinations are set. However, the present invention is not limited to this, and one type, two types, or four or more types of SB combinations may be set.
Further, in this example, the symbols are set so that the symbols of the 15 SBs that are the SB role and the specific small role are common to the middle reel 2C and the right reel 2R, but in the middle reel 2C or the right reel 2L. It can also be set so that the symbol of each role is different.

  Furthermore, the slot machine 1 of this example is provided with the specific small combination flag notifying means 44 for notifying the internal winning flag of the 15-piece combination which is the specific small combination, but instead of this, the SB which is a minus bonus combination. You may provide the minus bonus flag alerting | reporting means which alert | reports the internal winning flag of a combination. In this case, a player who knows the establishment of the internal winning flag of the SB combination that is a minus bonus combination can give a sense of tension so that the SB combination is never won in the game.

  Further, the slot machine 1 may include a specific small combination flag notification unit 44 and a minus bonus flag notification unit. In this case, in the game in which the internal winning flag for the 15 winning combination is notified in the assist time, the player is aiming for the 15 winning combination, and in the game in which the internal winning flag for the SB winning negative bonus is notified. It is possible to play a game while enjoying the two patterns, such as aiming not to win the SB combination.
