Description

  The present invention relates to a slot machine capable of simultaneously winning a plurality of bonus combinations.

  In the conventional slot machine, it has been proposed to increase the interest wave by changing the internal winning probability of the bonus combination to enhance interest (see, for example, Patent Document 1).

Japanese Patent No. 2627713

  However, even if the internal winning probability is high, the bonus combination is not always instantly won internally, and there is a problem that there are cases where it is not easy to continue. In addition, the game in the bonus state tends to be monotonous, and there is a problem that the game is poor.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a slot machine that can increase the continuous rate of bonus combinations and increase the game playability in a bonus state.

According to the first aspect of the present invention, there is provided a symbol variation display means for variably displaying a plurality of types of symbols in accordance with a predetermined arrangement in a plurality of symbol display areas in which a plurality of effective lines are set, and a game in a state where a game medium is inserted. A game start operation means operated by a player to start the game, and a plurality of types of combinations including at least a first bonus combination, a second bonus combination, and a small combination when the game start operation unit is operated. The internal lottery means for determining one or two or more internal winning combinations, and the internal lottery means for establishing the internal winning combination flag, and the symbol fluctuation display means for stopping the symbol fluctuation display a stop operation means for player operates, when the stop operation means is operated, before draw on the effective line on within a predefined pull-in range of the symbols corresponding to the internal winning A display control means for stopping displayed on the symbol display area, and the winning determination means for determining whether or not a winning occurs based on a combination of symbols stopped and displayed on each active line of the symbol variable display means, the winning When the determination means determines that a winning has occurred, a profit granting means for giving a profit corresponding to the winning to the player, and when the game ends, the small role flag is erased. Flag control means capable of carrying over the flags of the first bonus combination and the second bonus combination to the next game until the first bonus combination and the second bonus combination win, and the first bonus combination and the second bonus when any one of the bonus combination is determined to be winning by the winning determination device in a state where the winning flag of is established at the same time, the first bonus shape favorable for the player While generating, when a combination predetermined multi bonus is determined to be winning generates favorable MB state for the player, the one of the flag of the first bonus combination and the second bonus combination is established When the bonus determination means determines that the bonus combination has been won in a state in which the player is in a state, a second bonus state that is advantageous to the player is generated, and predetermined end conditions are established in the first bonus state and the second bonus state. The first bonus state and the second bonus state are ended when the first bonus combination and the second bonus combination end condition are both satisfied in the MB state. And a bonus state generating means for ending the state, wherein the display control means is configured to display the diagram in the first bonus state. Control is performed so that the effective line that preferentially draws the pattern differs from the effective line that preferentially pulls the pattern in the second bonus state .

The invention as set forth in claim 2, prior SL internal lottery means executes internal lottery to determine the internal winning combination in different probabilities depending on the whether the second bonus state or a first bonus state It is characterized by doing.

  According to the first aspect of the present invention, when a plurality of bonus combinations are won at the same time in a single lottery, a consecutive bonus game is quickly generated by winning the next bonus combination immediately after the end of the bonus state. It is possible to make it. In addition, in the bonus state, the pull-in control of the small role symbol is executed in a different manner depending on whether or not an unwinned bonus role flag remains, so the presence or absence of the bonus role flag is determined by observing the pull-in status of the small role symbol. Can be guessed, the gameability in the bonus state is improved, and the interest is enhanced.

  According to the invention of claim 2, in the bonus state, the internal lottery for determining the internal winning combination is performed with different probabilities depending on whether or not an unwinned bonus combination flag remains. A sense of tension and a sense of tension increase, and interest increases.

Hereinafter, a slot machine according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 2 schematically shows a front appearance of the slot machine 1. A display window 2 is provided in front of the slot machine 1, and a player can visually recognize a symbol of a reel (corresponding to symbol variation display means) 3 provided therein through the display window 2. In this case, the symbols are drawn on the circumferential surfaces of the left reel 3a, middle reel 3b, and right reel 3c. This symbol is displayed corresponding to the upper, middle and lower stages of the display window 2 when the reels 3a to 3c are stopped. That is, the display window 2 is formed with a symbol display area for a total of nine symbols, three symbols for each of the reels 3a to 3c.

  As shown in FIG. 3, the display window 2 has a total of five (one in the horizontal direction corresponding to the middle stage (solid line indicated by 1 in FIG. 3), two in the oblique direction corresponding to the upper, middle and lower stages ( There are two V-shaped effective lines (dashed lines indicated by 4 and 5 in FIG. 3) corresponding to the upper and middle stages, the lower and middle stages, and the winning symbols. The corresponding winning line is generated when all of the active lines are aligned on any of the active lines, and the number of active lines is always 5 regardless of the difference in the gaming state described later.

  Above the display window 2 is a liquid crystal display unit 4 (special bonus earned game medium number display means, individual bonus earned game medium number) for displaying information such as the payout progress status of medals (corresponding to game media) and various images. Display means) and a speaker 5 are provided. Below the display window 2, there are provided a BET button 6 for inserting a credit medal, a settlement button 7 for settlement of a credit medal, and a medal insertion slot 8 for inserting a medal. A start lever 9 corresponding to operation means, a left stop button 10, a middle stop button 11, and a right stop button 12 corresponding to stop operation means are provided.

  On the right side of the display window 2, a payout number display unit 13 for displaying the number of paid out medals and a credit number display unit 14 for displaying the number of credited medals are provided. The credit number display unit 14 displays the number of medals that have not yet been used in the game among the medals inserted from the medal insertion slot 8, and the number of medals awarded when a winning occurs in the game. When the settlement button 7 is operated in a state where the number of credits is 1 or more, medals corresponding to the credit amount are paid out. A tray 15 is provided at the lowermost front part of the slot machine 1, and a decorative lamp part 16 is provided at the uppermost front part of the slot machine 1.

Next, the electrical configuration of the slot machine 1 will be described.
FIG. 1 shows the electrical configuration of the slot machine 1 as functional blocks. The control unit 17 (internal lottery means, display control means, winning determination means, profit granting means, flag control means, bonus state generating means) is constituted by a microcomputer equipped with a CPU, ROM, RAM, I / O, and the like. Various operation signals are input from the BET button 6, the checkout button 7, the start lever 9, the left stop button 10, the middle stop button 11, the right stop button 12, the inserted medal detection unit 18, the set value operation unit 19, and the like. .

  When the inserted medal detection signal is input from the inserted medal detection unit 18 that determines the authenticity and quantity of medals inserted into the medal slot 8, the control unit 17 is inserted based on the number of the input signals. Count the number of medals. When the number of medals exceeds a predetermined number required for one game (in this embodiment, three in the normal state), the number of medals for the excess is set as a credit number, for example, a predetermined upper limit value (e.g., RAM). (For example, 50) and the number of credits is displayed on the credit number display unit 14. In addition, various setting signals such as a winning probability are input to the control unit 17 from the setting value operation unit 19. In the setting value operation unit 19, after the setting change key 20 is inserted to make the setting changeable, the setting value is changed by switching the DIP switch, for example.

  The control unit 17 also drives the reel display motor 21 corresponding to the liquid crystal display unit 4, various display units such as the payout number display unit 13 and the credit number display unit 14, the decorative lamp unit 16, and the reels 3a to 3c. Based on the drive unit 22, the sensors 23a to 23c that detect the passage of the reference position pieces provided on the reels 3a to 3c, and the detection signals from the sensors 23a to 23c, the reference positions of the reels 3a to 3c are detected. The reference position detection unit 24 and the audio output unit 25 that drives the speaker 5 are connected. In addition, it is connected to a medal payout unit 26 for paying out medals, and when the checkout button 7 is operated, the medal payout unit 26 is controlled so as to pay out medals corresponding to the stored number of credits. The display of the number display unit 14 is set to zero.

  The control unit 17 includes a random number generation unit 27 (corresponding to a random number generation unit) and a random number extraction unit 28. When the start lever 9 is operated with a medal inserted (game start operation is performed). When the random number generator 27 extracts one random number from the random numbers generated by the random number generator 27, the internal lottery is executed.

  The control unit 17 controls the operation of the slot machine 1 based on each input signal and the control program stored in the ROM or the like, and, for example, the number of used media (number of consumed medals) according to the progress of the game. Out signal (1 pulse output every time a medal is inserted or 1 credit medal is inserted), and a safe signal (1 per medal payout) that can specify the number of payout media (number of medals paid out) Games such as pulse output), game signals that can specify the number of digested games (one pulse output each time a game starts), and bonus signals that can specify a gaming state (in particular, a bonus state) (level signal output during the bonus state). A signal is generated and output from a signal output terminal (not shown) to the outside. Each game signal output from the signal output terminal is input to a management device (not shown) or the like installed in the game arcade, and is used to manage the operation status of each slot machine 1.

  FIG. 4 shows a symbol arrangement drawn on the circumferential surface of the reel 3, and FIG. 5 shows a winning structure corresponding to each symbol. There are three types of combinations set in the slot machine 1; a bonus combination, a small combination, and a replay combination. Of these, the bonus combination includes a multi-bonus combination (MB combination) and a first bonus combination or Three types of big bonus combinations (BB1 combination to BB3 combination) corresponding to the second bonus combination are set. Three types of small role, 10 types, 3 types, and 1 type, and three types of replay A, Replay B, and Replay C are set. The number of medals inserted in one game (BET number) is set to 3 (3 BET) in the normal state and 2 (2 BET) in the bonus state described later.

Here, the gaming state provided in the slot machine 1 will be described. The slot machine 1 is provided with three types of game states: a normal state, a BB state, and an MB state. Among these, the BB state is further provided with a first BB state and a second BB state. The gaming state of the slot machine 1 is switched according to the establishment of a predetermined condition, and the slot machine 1 is in a normal state at the time of initialization (when the power is turned on or at the time of resetting).
In the normal state (non-bonus state), the slot machine 1 gives the player the benefit of paying out the corresponding medal according to the small combination won by the player. Further, when the replay combination wins, the player is given a profit that the game can be executed again without newly inserting medals. The normal state is the gaming state with the lowest payout rate and the number of BETs is 3, and is the most disadvantageous gaming state for the player.

  When the bonus combination wins in the normal state, the player is given a benefit of occurrence of the bonus state. For example, when any of the BB1 role to BB3 role wins, the state shifts to the BB state. This BB state is a state in which the internal winning probability of the small role is greatly increased, and continues until the number of medals paid out in the BB state exceeds 250. In other words, the fact that the number of medals paid out exceeds 250 corresponds to a predetermined end condition of the bonus state. Although details will be described later, when the BB1 combination to the BB3 combination are simultaneously won and the MB lottery is won, when the player wins the MB combination, the state shifts to the MB state. This MB state is a state in which a plurality of BB states are continuously continued, and continues until the number of medals paid out exceeds (the number of BB combinations won simultaneously) × 250.

  In each of these bonus states, the payout of all small combinations is set to 15 and the BET number is reduced to 2 (2 BET). Therefore, it can be said that the bonus state is the most advantageous gaming state for the player because a large number of medals can be obtained at once. When the bonus state ends, the slot machine 1 shifts to the normal state.

  FIG. 6 is a diagram showing the number of internal lottery random numbers such as the bonus combination and the small combination and the internal winning probability. The slot machine 1 extracts one of the random numbers generated between 0 and 65535 as a random number for lottery, and determines the internal winning combination by comparing the extracted random number for lottery with a winning random number table (not shown). . The winning random number table defines a range of winning random numbers corresponding to each winning combination, and the winning combination corresponding to the range to which the extracted random number for lottery belongs is an internal winning winning combination. The winning random number table is set in accordance with the gaming state of the slot machine 1 and for each set value of the slot machine 1, and the range of the winning random number corresponding to each combination varies depending on the gaming state and the setting value. FIG. 6 illustrates the number of internal lottery random numbers and the internal winning probability in the normal state and the BB state.

  In a normal state, a predetermined number of random numbers are assigned to the replay combination, small combination, and bonus combination. In a normal state, a plurality of BB roles are considered to have been internally elected at the same time, BB123 role (all BB1 role to BB3 role are elected simultaneously), BB12 role (BB1 role and BB2 role are elected simultaneously), BB13 role (BB1 BB23 role (BB2 and BB3 roles are elected simultaneously), BB1 role, BB2 role, BB3 role, each small role, and replay A role A random number is allocated. If the bonus combination flag is established in the normal state, the bonus combination is excluded from the internal lottery.

  In this embodiment, for example, 20 winning random numbers are allocated to the BB123 combination which is a bonus combination, 30 BB12 to BB23 combinations, and 50 BB1 to BB3 combinations. For this reason, the probability that the BB123 role is won internally is about once in 3276.8 games, the probability that the BB12 role-BB23 role is won internally is about once in 2184.5 games, and the BB1 role-BB3 role is The probability of winning internally is about 1310.7 games.

  In addition, 8000 winning random numbers are assigned to the 10 winning combinations, 1500 winning the 3 winning combinations, 500 winning random numbers, and 8980 winning random numbers being assigned to the Replay A winning combination. It is. For this reason, the probability that the 10 winning combination will be won internally is about once in 8.2 games, the probability that the 3 winning combination will be won internally is about once in 43.7 games, and the probability that the 1 winning combination will be won internally is about 131. The probability that the replay role will be internally won once per game is about once per 7.3 games. In the normal state, the winning random numbers are not assigned to the replay AB combination and the replay AC combination.

  On the other hand, in the BB state, the winning random number is not allocated to the bonus combination, and the winning random number is allocated only to the small combination and the replay combination. Of these, 4500 random numbers are assigned to each of the small roles, and it is set to be internally won at a rate of about 14.6 games. In addition, 15000 random numbers are assigned to each replay combination, and an internal winning is made at a rate of about once every 4.4 games.

  Next, the first BB state and the second BB state provided in the MB state and the BB state will be described in detail. As described above, in the bonus combination, each BB combination is independently won internally, and two or more BB combinations are considered to have been internally selected at the same time. There is a case. At this time, when the BB 123 combination, the BB 12 combination, the BB 13 combination, and the BB 23 combination are won internally, MB lottery is executed. In the following description, for example, a state in which a plurality of BB roles are considered to have been internally won at the same time, such as when the BB12 role has been internally won, is expressed as “simultaneous winning” for convenience.

  FIG. 7 shows the number of each winning random number in the MB lottery. Two of the 20 internal winning random numbers shown in FIG. 6 are allocated to the BB123 combination as MB winning random numbers. Further, three of the 30 internal winning random numbers shown in FIG. 6 are allocated as MB winning random numbers to the BB12 winning combination to BB23 winning combination. That is, the MB winning probability of each bonus combination in the MB lottery is 10%. In the MB lottery, when MB is won, winning of MB combination (see FIG. 5) is permitted, but each BB combination is prohibited from winning individually. When the player wins the MB combination in this state, the player moves to the MB state, and one bonus state (MB state) continues until all the BB combinations won simultaneously are consumed.

  This MB state continues until the MB state end condition is satisfied, without winning an individual BB combination. For example, when the BB1 role and the BB2 role are simultaneously elected (BB12 role is an internal winner) and the player wins the MB role, the payout number of medals exceeds 250 × 2 = 500 MB state continues until. However, in the MB state, a process in which individual BB states are sequentially shifted is performed internally.

  On the other hand, when the MB is not won, the MB combination winning is not permitted, and the player sequentially wins the individual BB winning combinations. In this state, if any of the BB combinations won simultaneously by the player is won, the state shifts to the BB state, and the BB state is continued until the above-described termination condition is satisfied. At this time, the BB combination flag that has not been won (the flag corresponding to the BB combination that has not been won among the BB combinations that have been won simultaneously) is carried over until the BB combination wins. In other words, during the BB state corresponding to the BB combination that the player has won first, the state where the flag for the non-winning BB combination is established continues. Thus, the BB state in which the other BB combination flag is established is referred to as a first BB state.

In addition, a BB state generated by winning a BB combination that is internally won independently, that is, not a simultaneous winning, that is, a BB state in which no other BB combination flag is established, is referred to as a second BB state.
In the slot machine 1 configured as described above, in the internal lottery executed in response to the start of the game, when the result of the internal lottery is a win (when there is an internal winning combination), it corresponds to the internal winning combination The internal winning combination flag (bonus combination flag, small combination flag or replay combination flag) is turned on (established). At this time, the bonus combination flag is carried over for any number of games until the bonus combination is won, while the small combination flag and the replay combination flag are deleted by the start of the next game regardless of whether or not a winning combination is made.

  The slot machine 1 performs stop control (respective reels 3a to 3c) including so-called pull-in control (slip control) based on a stop table (not shown) for determining stop positions of the reels 3a to 3c according to the internal winning combination flag. Is controlled at a winning symbol or a lost symbol according to the type of the internal winning combination flag. This pull-in control is a control capable of pulling a symbol within a predetermined pull-in range (up to four symbols at the maximum) from the time point when the operation of each of the stop buttons 10 to 12 is detected and stopping it. . When the symbol corresponding to the internal winning combination flag does not exist within the above-described drawing range, the symbol cannot be drawn on the active line and stopped, so that no winning is generated and so-called losing is made.

  The slot machine 1 is provided with three types of stop tables: a normal table corresponding to the normal state, a reel control table 1 corresponding to the first BB state, and a reel control table 2 corresponding to the second BB state. The slot machine 1 is configured to use these stop tables properly according to the current gaming state.

  Among these, the reel control table 1 is a table set to execute control for preferentially drawing 10 symbols on the active line 2 or 3 (see FIG. 3). In addition, the reel control table 2 is a table that is set to execute a control for preferentially drawing the 10 symbols in the active line 4 or 5 (see FIG. 3). In the case where the reel control table 1 is used, when the combination of 10 sheets cannot be drawn onto the effective line 2 or 3, control is performed so as to draw it onto the effective line 4 or 5. Similarly, in the case where the reel control table 2 is used, when the 10-sheet combination cannot be drawn onto the effective line 2 or 3, control is performed to draw it onto the effective line 2 or 3.

Next, the operation of the slot machine 1 configured as described above will be described.
The control unit 17 executes a process for controlling the entire slot machine 1, and when the start lever 9 is operated in a state where a prescribed number of medals are inserted, it is determined that the game has started and the internal A lottery process is executed. In this internal lottery process, the random number generated by the random number generation unit 27 is extracted by the random number extraction unit 28, checked against the winning random number table corresponding to the current gaming state, and the corresponding internal winning combination flag is set according to the comparison result. Turned on.

When the internal lottery process is completed, the control unit 17 starts (rotates) the reel 3 and causes the corresponding reels 3a to 3c to be stopped and displayed by the pull-in control according to the operation of the stop buttons 10 to 12 by the player. Execute stop processing.
FIG. 8 is a flowchart showing the reel stop process. When the reel 3 is rotating (A1: YES), the control unit 17 determines whether each stop button 10-12 is turned on (operated) (A2), and the stop button 10-12 is operated. If it is determined (A2: YES), it is determined whether the BB state flag is ON (whether established) (A3). This BB state flag is a flag for determining whether or not the gaming state of the slot machine 1 is the BB state, and is turned on in the BB state. When the BB state flag is not on (A3: NO), the stop position of the reel 3 is determined with reference to the normal table (A8), and then the reel 3 is pulled into the determined stop position and stopped (A6).

  On the other hand, when the BB state flag is ON (A3: YES), the control unit 17 determines whether the state is the BB1 state (A4). When it is in the BB1 state (A4: YES), after determining the stop position with reference to the reel control table 1 (A5), the reel 3 is pulled into the determined stop position and stopped (A6). In this case, control is performed so that the ten symbols are preferentially drawn onto the effective line 2 or 3. Therefore, for example, when the player presses the 10 symbols to stop display on the active line 4 or 5, when the 10 symbols are stopped and displayed on the effective line 2 or 3, It can be estimated that there is a high possibility that the current gaming state is the BB1 state.

Further, when not in the BB1 state (A4: NO), the control unit 17 determines the stop position with reference to the reel control table 2 (A7), and then pulls the reel 3 to the determined stop position and stops it ( A6). In this case, the 10 symbols are preferentially drawn on the active line 4 or 5. Therefore, for example, when the player presses the 10 symbols in order to stop display on the active line 2 or 3, when the 10 symbols are stopped on the effective line 4 or 5, It can be estimated that there is a high possibility that the current gaming state is the BB2 state.
As described above, in the slot machine 1, in the BB state, the pull-in control is performed so that the 10-sheet combination is stopped and displayed on the active line in a different manner depending on whether or not the other BB combination flag is established. ing.

According to this embodiment described above, the following effects can be obtained.
If MB is not won at the same time when multiple BB roles are considered to be won simultaneously in one lottery, when the individual BB role is won, the BB role wins an unwinned BB role flag Since any number of games are carried over until the end of one BB state, the consecutive BB state can be promptly generated by winning the next BB combination immediately.

In the BB state, the pull-in control of the 10-piece role symbol is executed in a different manner depending on whether or not an unwinned BB role flag remains. It becomes possible to guess, gameability in the BB state is improved, and interest is increased.
In the case where a plurality of BB winning combinations are won simultaneously in one lottery, when MB is won, control is performed so that the BB state is internally changed. Therefore, in the MB state, that is, one continuous bonus state. A large number of medals can be obtained at once, and the player's satisfaction can be enhanced.

(Other embodiments)
If it is decided to win the MB, winning the BB role symbol is prohibited and only the MB role symbol can be won, but the BB role symbol can also be won, and the player can arbitrarily win any of them. You may be able to do that. In addition, when the BB combination is won at the same time, it may be possible to always win an MB combination symbol.
Although one MB role symbol is used, two or more MB role symbols may be provided. In addition, the MB symbol may be omitted.
The type / number of bonus combinations is not limited to this example. Any bonus combination may be used as long as it shifts to a state more advantageous to the player than the normal state, and there may be any number of bonus combinations.

Also, the bonus condition end condition is not limited to this example, and various conditions can be set.
The simultaneous winning pattern of bonus combination is not limited to this example. The simultaneous winning combination can be set as appropriate.
You may set so that the internal winning probability of a small role may differ in the 1BB state and the 2BB state. With such a configuration, the presence / absence of the BB combination flag can be estimated from not only the winning line but also the winning frequency. Furthermore, the player's expectation in the bonus state is improved and the interest is enhanced.

  Although the reel control table 1 is always used in the first BB state, either the reel control table 1 or the reel control table 2 may be selected by lottery and used. In this way, even if the reel control table 2 is selected, there is a possibility that the BB combination flag remains, so that the player's sense of expectation for the continuous chain can be maintained.

  In the drawings, 1 is a slot machine, 3 is a reel (design variation display means), 9 is a start lever (game start operation means), 10 to 12 are stop buttons (stop operation means), 17 is a control unit (internal lottery means, Display control means, winning determination means, profit giving means, flag control means, bonus state generating means).
