Description

  The present invention relates to a slot machine.

  A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, winning is determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize group will be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or a plurality of roles and corresponds to a lottery category. That is, a prize group and a combination may correspond one-to-one, or a plurality of combinations may correspond to one prize group.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop timing is delayed, Control is performed so that symbols constituting the winning combination do not stop on a valid winning line. On the other hand, if a prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line.

  In such a slot machine, a so-called assist game (hereinafter referred to as an AT game) is known as a method for changing the winning probability while maintaining the internal winning probability of a specific combination. This is to control the reels so that even if the specific combination is won internally in the normal game, the reel stop button cannot be won unless the operation order of the reel stop buttons is the predetermined pressing order, while in the AT game, the pressing order is notified to the player. Is.

A slot machine equipped with an AT game is provided with a sub CPU in addition to the main CPU to control lighting / extinction of a lamp provided on the back of the reel in accordance with a command from the sub CPU, or to the liquid crystal display device next. Generally, an image showing a reel stop button to be operated is displayed (for example, Patent Document 1).

  However, in a slot machine capable of executing an AT game, there is a problem that the control becomes complicated because it is necessary to inform the player of the pressing order.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a slot machine that changes the winning combination probability of a specific combination while maintaining the internal winning probability of the specific combination with a simple configuration.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The slot machine according to the present invention includes display means including a plurality of display columns (R1 to R3) capable of variably displaying a plurality of types of symbols, and the plurality of display columns (R1 to R3) are stopped. When the arrangement of symbols stopped on the predetermined winning line (L1 to L5) crossing the display row (R1 to R3) is in a predetermined mode, the winning combination including the specific combination is won, and the game value corresponding to the winning combination is obtained. A slot machine that is capable of executing a first gaming state and a second gaming state that have different drawing probabilities for at least one combination, and each division corresponding to each prize group that is a collection of one or more combinations A first lottery table (TBLA) that stores the width and the width of the division of loss, and a first lottery in which at least one of the division widths stored in the first lottery table (TBLA) has a different width Table (TBLB Then, referring to the designated first lottery table (TBLA) or first lottery table (TBLB), one lot is drawn from each section, and the internal lottery information (ISD) indicating the lottery result is displayed in the game. A lottery means (31, 33) to be generated every time, and a first stop in which first stop data is recorded which is unlikely to align the winning symbols (L1 to L5) with the specific symbol combination. The table (a1) and the second stop data in which the second stop data is more likely to be aligned on the winning line (L1 to L5) than the first stop data. 2 stop table (b1), and in the first gaming state, specifies that the first lottery table (TBLA) is used for the processing of the lottery means (31, 33) and the first stop table (a1 To use the first lottery table (TBLB) for the processing of the lottery means (31, 33) in the second gaming state and to use the second stop table (b1) And the first stop read from the first stop table (a1) when the internal lottery information (ISD) indicates the winning of the specific combination in the first gaming state. While the stop position of each display row (R1 to R3) is controlled based on the data, when the internal lottery information (ISD) indicates the winning of the specific combination in the second gaming state, the second stop Control means (31) for controlling the stop position of each of the display columns (R1 to R3) based on the second stop data read from the table (b1).

  According to the present invention, the lottery table and the stop table are switched according to the gaming state. Accordingly, it is possible to reduce the processing load of the designation means as compared with the case where the stop table is selected for each game. Further, since the stop table is switched in conjunction with the switching of the lottery table, it is possible to simultaneously specify a combination of the lottery table and the stop table according to the gaming state, and the processing load can be reduced. More specifically, the designation means can designate a combination of a lottery table and a stop table only by referring to a game state flag indicating a game state. In addition, since the second stop data is more likely to have the winning symbols on the winning line compared to the first stop data, the winning ratio of the specific combination is changed while maintaining the winning probability of the internal lottery. It becomes possible. In addition, since it is not necessary to notify the pressing order as in the so-called AT game, the winning rate of the specific combination can be changed with a simple configuration. As a result, the taste of the game is greatly improved. In addition, the number of specific combinations may be more than one, and further, if at least one specific combination among the plurality of specific combinations is internally elected to the specific combination and is in the second gaming state, the second stop You may make it perform stop control of each display row using the 2nd stop data read from the table.

  Another slot machine according to the present invention includes display means including a plurality of display columns (R1 to R3) capable of variably displaying a plurality of types of symbols, and the plurality of display columns (R1 to R3) are stopped. In the case where the arrangement of symbols stopped on the predetermined winning line (L1 to L5) crossing the plurality of display rows (R1 to R3) is in a predetermined mode, the winning combination including the specific combination is won, and the winning combination is determined. A slot machine that can execute a first gaming state and a second gaming state with different game values and different lottery probabilities, and corresponds to each prize group that is a collection of one or more roles. A first lottery table (TBLA) that stores the width of each section and the width of the losing section, and the width of at least one of the sections stored in the first lottery table (TBLA) is Different first lottery table TBLB) and the designated first lottery table (TBLA) or the first lottery table (TBLB), one lot is drawn from each section, and internal lottery information (ISD) indicating the lottery result Lottery means (31, 33) for generating each game, and first stop data in which it is impossible to align the winning symbols (L1 to L5) on the winning line (L1 to L5). The second stop table (b1) on which the first stop table (a1) and the second stop data capable of aligning the winning symbols for the specific combination on the winning line (L1 to L5) are recorded. ) Including the stop table group (C)) and the use of the first lottery table (TBLA) for the processing of the lottery means (31, 33) in the first gaming state and the second stop table. The first stop table (a1) group including the first stop table (a1) and including the first stop table (a1) is designated, and the lottery means (31, 33) is processed in the second gaming state. A second stop table that specifies that the first lottery table (TBLB) is to be used and includes the first stop table (a1) and the second stop table (b1) from the stop table group (C) ( b1) a designation means (31) for designating the use of a group, and the first stop table (a1) group when the internal lottery information (ISD) indicates the winning of the specific combination in the first gaming state. The first stop table (a1) is selected from the first stop table (a1), and the stop positions of the display columns (R1 to R3) are controlled based on the first stop data read from the first stop table (a1). On the other hand, when the internal lottery information (ISD) indicates the winning of the specific combination in the second gaming state, the second stop table (b1) is selected from the second stop table (b1) group. The stop position of each display row (R1 to R3) is controlled based on the second stop data read from the second stop table (b1), and the internal lottery information (ISD) is stored in the second gaming state. In the case of indicating a loss, the first stop table (a1) is selected from the second stop table (b1) group, and based on the first stop data read from the first stop table (a1). While controlling the stop position of each said display row | line | column (R1-R3), the control means (31) was provided.

  Generally, the winning combination in the internal lottery and the stop table used for stop control are associated one-to-one. In the present invention, in the first gaming state, even when the specific combination is won by the internal lottery, winning in the specific combination can be avoided in the stop control of the display row. In this case, it is possible to use a stop table that controls the display column so that a specific combination is not won. However, if such a stop table is specially provided, the storage means increases the number of stop tables and stores the stop table. Will increase the storage capacity. Therefore, in the present invention, a stop table for losing is adopted as the first stop table, and this is also used as a stop table for losing in the second gaming state. In other words, the stop table is also used between different gaming states. Thereby, the number of stop tables can be reduced and the hardware configuration can be simplified.

  Note that “can be aligned” includes a case where the winning symbol can be aligned on the winning line by the pull-in control within the predetermined number of symbols. Therefore, “can be aligned” allows not only the case where the winning symbols are aligned on the winning line, regardless of how the stop operation means is operated, but also so-called missing.

  Another slot machine according to the present invention includes display means including a plurality of display columns (R1 to R3) capable of variably displaying a plurality of types of symbols, and the plurality of display columns (R1 to R3) are stopped. In the case where the arrangement of symbols stopped on the predetermined winning line (L1 to L5) crossing the plurality of display rows (R1 to R3) is in a predetermined mode, the winning combination including the specific combination is won, and the winning combination is determined. A lottery machine that gives a gaming value, and draws one lottery from lottery categories including each category corresponding to each award group that is a group of one or more roles and a category of losing, and a lottery result is obtained. The lottery means (31, 33) for generating the internal lottery information (ISD) shown for each game, and it is impossible to align the winning symbols (L1 to L5) on the winning lines (L1 to L5). The first stop where the first stop data is recorded A table (a1), and a second stop table (b1) in which second stop data is recorded, which can align a line of symbols for winning for the specific combination on the winning line (L1 to L5). Stop table group (C), determination means (31) for determining whether or not a predetermined condition is satisfied, and the predetermined condition is not satisfied, and the internal lottery information (ISD) When winning is selected, the first stop table (a1) is selected, and the stop positions of the display columns (R1 to R3) based on the first stop data read from the first stop table (a1). When the predetermined condition is satisfied and the internal lottery information (ISD) indicates that the specific combination is won, the second stop table (b1) is selected and the second stop Read from table (b1) When the stop position of each display row (R1 to R3) is controlled based on the second stop data that has been issued, the predetermined condition is satisfied, and the internal lottery information (ISD) indicates a loss Control means for selecting the first stop table (a1) and controlling the stop positions of the display columns (R1 to R3) based on the first stop data read from the first stop table (a1). 31).

  According to the present invention, when the predetermined condition is not satisfied, even if the specific combination is won by the internal lottery, the winning for the specific combination can be avoided in the stop control of the display row. In this case, it is possible to use a stop table that controls the display column so that a specific combination is not won. However, if such a stop table is specially provided, the storage means increases the number of stop tables and stores the stop table. Will increase the storage capacity. Therefore, in the present invention, a stop table for losing is adopted as the first stop table, and this is also used as a stop table for losing when a predetermined condition is not satisfied. Thereby, the number of stop tables can be reduced and the hardware configuration can be simplified.

  4) Watermelon role This role is a symbol number PN = 15, 13, 5 or 3 in the left reel R1, a symbol number PN = 18, 16, 12, or 5 in the middle reel R2, and a symbol number PN in the right reel R3. = 20, 16, 13, or 7 symbol arrangement.

  5) Cherry role This role only needs to stop when the symbol number PN = 20, 12 or 1 on the left reel R1 is activated among the winning lines L1 to L5. What is the stop position of the other reels? Unrelated.

  6) Replay role This role consists of a symbol number PN = 18, 16, 9, 6 or 1 on the left reel R1, a symbol number PN = 20, 15, 13, 6 or 4 on the middle reel R2, and a right reel. This is an arrangement of symbols of symbol number PN = 17, 14, 10, or 5 in R3. Even if a replay role is established, no medal is paid out, but replay (replay) is possible. Re-playing means playing a game again without newly inserting medals.

  For these roles, game values to be given to the player for each role are determined in advance. For a combination, a combination with 1 to 15 payouts, a combination with an advantageous gaming state such as a big bonus or regular bonus, regardless of whether or not there is a payout due to winning, and a medal with no payout Without replaying the game, there is a role in which a re-game that can be played under the same number of medal insertion conditions is given again. Further, not all of these combinations are always determined as prizes in any gaming state. It is possible to have a combination that is established as a prize in one gaming state but not established as a prize in another gaming state. That is, the game value given to the player for each winning combination is determined in advance for each gaming state and is not always constant.

  In this embodiment, the game value given to the player in the normal gaming state is paid out for 7 bells, 15 watermelons, and 2 cherrys, and replays can be replayed It becomes a role to become.

  Among the various types of roles, the names corresponding to relatively low game values such as 2 to 15 dividends and replays such as a bell, watermelon, cherry and replay roles are collectively referred to as small. Called a role. On the other hand, when the BAR combination wins, the gaming state shifts to a second special gaming state called a regular bonus (hereinafter abbreviated as “RB” where appropriate). With the regular bonus, the jack game can be played 12 times, and the RB period ends when the jack game is played 12 times or a maximum of 8 times. The jack game is played by betting one medal and enabling only the central pay line L1. A replay role is adopted as the role of the jack game. When the symbols constituting this combination are aligned with the winning line L1, the slot machine 1 pays out 15 medals. In other words, in the normal gaming state, even if the replay combination is complete, replay can only be performed, but in the jack game performed during the regular bonus period, 15 medals will be paid out when the symbols constituting the replay combination are complete. Can do. In addition, during the big bonus described later, a replay role is assigned to the regular bonus award. In addition, since a jack game that is not in the normal gaming state is played in the RB gaming state, it can be said that the RB gaming state is an advantageous gaming state for the player as compared to the normal gaming state.

  Further, when winning a red 7 role, the gaming state shifts from the normal gaming state to a first special gaming state called a big bonus (hereinafter, the big bonus is abbreviated as “BB” if necessary). . During the big bonus period, in addition to being able to play regular bonuses up to 3 times, it is possible to establish a small role game with a high win probability state up to 30 times. The big bonus is a more advantageous gaming state compared to the regular bonus. In the following description, in order to distinguish between the regular bonus in the big bonus and the regular bonus that has been won alone, the former is referred to as BB middle RB, and the latter is referred to as single RB.

  Among the small roles, the cherry role and the bell role cannot be aligned on the winning line by reel control during the period when the BB winning flag, which will be described later in the normal beam, is not set. During the period when the BB winning flag is set, at least one of the cherry role and the bell role can be arranged. In the following description, the cherry role is called the specific role 1 and the bell role is called the specific role 2 as necessary.

<1-3: Electrical configuration of slot machine>
FIG. 5 is a block diagram showing a control device that controls the game processing operation in the slot machine 1 and a circuit configuration including peripheral devices related to the present invention among those constituting the slot machine 1.

  The control device includes main board 30A and sub board 30B as main components. The main board 30A includes a CPU 31, a clock generation circuit 32, a sequence generation circuit 33, a RAM 34, a ROM 35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38 and an output port 39.

  The CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 executes the first control program CP1 and controls each component. The first control program CP1 describes how to operate the entire slot machine 1. For this reason, the CPU 31 functions as a control center of the slot machine 1. The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a reference clock signal CLK having a fixed period, and supplies the reference clock signal CLK to the CPU 31 and the number sequence generation circuit 33.

  The sequence generator 33 is composed of a high-speed ring counter, and counts the reference clock signal CLK to generate count data CD. The numerical value range of the count data CD is, for example, 0 to 59999, depending on the contents stored in the prize group lottery table TBL1 described later. The count data CD is constantly supplied to the CPU 31. The CPU 31 detects the timing when the player depresses the start lever 6, and generates the sampling data SD by sampling the count data CD at the timing.

  Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pushed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value sampled from a random number. Since the sequence generator 33 operates in synchronization with the reference clock signal CLK, the cycle of the count data CD is extremely short. For example, if the frequency of the reference clock signal CLK is 30 MHz, the time required for the value of the count data CD to change from “0” to “59999” is 2 msec. Therefore, even if the player can know the value of the count data CD by unauthorized means, it is impossible to cause the CPU 31 to generate sampling data SD having a desired value by operating the start lever 6.

  Next, the RAM 34 functions as a work area of the CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like. For example, internal lottery data ISD indicating the result of the internal lottery is stored in the RAM 34.

  In addition to the first control program CP1, the ROM 35 stores a prize group lottery table group TBL1, a stop table group TBL2, a winning symbol combination table TBL3, and the like. In the winning symbol combination table TBL3, combinations of winning symbol combinations and medal payout numbers for winning combinations are stored in association with each other.

  As described above, the types of roles in the slot machine 1 of the present embodiment include a red 7 role, a BAR role, a bell role, a watermelon role, a cherry role, and a replay role. The establishment of the red 7 combination is an opportunity to shift to the big bonus, while the formation of the BAR combination is an opportunity to shift to the regular bonus. In addition, the game value that a player can acquire varies depending on the type of small role. Since the control of the slot machine 1 requires control according to the difference in game value, it is convenient to classify various roles by paying attention to the game value. In the slot machine 1 of the present embodiment, one prize group is assigned to each combination, but one or more combinations may be assigned to one prize group. The prize group corresponding to the red 7 role is the BB prize, the prize group corresponding to the bell role (special role 2) is the bell prize, the prize group corresponding to the watermelon role is the watermelon prize, and the prize corresponding to the cherry role (special role 1). The group is called the Cherry Prize, and the prize group corresponding to the replay role is called the Replay Prize.

  Next, the prize group lottery table group TBL1 includes a plurality of prize group lottery tables. CPU31 performs internal lottery using the prize group lottery table selected according to the gaming state. As a prize group lottery table, a table used for a base game, a table used for a big bonus game, and a table used for a regular bonus game are prepared. Furthermore, the table used for the base game includes a table used when a BB winning flag described later is cleared and a table used when the BB winning flag is set.

  FIG. 6 shows the contents stored in the base game prize group lottery tables TBLA and TBLB. As shown in this figure, the prize group lottery table TBLA stores lottery division data in the first to seventh storage areas ADR1 to ADR7, respectively. The value of the lottery category data indicates the width of the lottery category corresponding to each prize group. For example, the lottery classification data stored in the first storage area ADR1 corresponds to the loss, and the value is “43647”. The lottery classification data stored in the third storage area ADR3 and the fourth storage area ADR4 correspond to the cherry award (specific combination 1) and the bell award (specific combination 2), and the value is “7000”. is there.

  The lottery division data stored in the prize group lottery table TBLB is the same as the prize group lottery table TBLA except for the divisions corresponding to the lose and replay prizes. In other words, the width of the predetermined combination (in this example, the replay combination) is increased, and the width of the loss classification is reduced correspondingly.

  FIG. 7 is a flowchart showing the operation of the CPU 31 in the internal lottery process using the prize group lottery table TBLA. First, the CPU 31 performs an initialization process (step S1). Specifically, the value of the variable N is reset to “0” and the value stored in the internal register is reset to “0”.

  Next, the CPU 31 stores the sampling data SD in the internal register (step S2), and subsequently changes the value of the variable N to N + 1 (step S3). Thereafter, the CPU 31 reads the lottery classification data from the Nth storage area (step S4). In the process immediately after the initialization process, since the value of the variable N is “1”, the lottery classification data is read from the first storage area ADR1. The value in this case is “54000”.

  Next, the CPU 31 reads the stored contents of the internal register, adds the read data value and the lottery classification data value, and stores the added value in the internal register (step S5). As a result, the content stored in the internal register is updated from the original data value to the added value.

  Next, the CPU 31 determines whether or not the added value is greater than or equal to the reference value (step S6). The reference value is equal to the sum of the values of the lottery classification data stored in the first to eighth storage areas ADR1 to ADR7.

  If the added value is less than the reference value, the CPU 31 returns the process to step S3, and repeats the processes from step S3 to step S6 until the added value becomes equal to or greater than the reference value. When the added value is equal to or greater than the reference value, the CPU 31 advances the process to step S7, determines a prize group according to the value of the variable N, and generates internal lottery data ISD. Specifically, when N = 1, it is lost, when N = 2, a replay prize, when N = 3, a cherry prize, when N = 4, a bell prize, when N = 5, a BB prize, when N = 6, an RB prize When N = 7, it is determined that the watermelon prize is won. As a result, as shown in FIG. 6A, the correspondence between the sampling data SD and the prize group is lost at SD = 59999-16353, replay prize at SD = 16352-14108, and cherry at SD = 14107-7107. The award corresponds to the bell award at SD = 7106-108, the BB award at SD = 107-40, the RB award at SD = 49-15, and the watermelon award at SD = 15-0.

  Then, the CPU 31 generates internal lottery data ISD based on the determination result. The internal lottery data ISD is 8-bit data. The first bit is the BB prize, the second bit is the RB prize, the third bit is the Bell prize, the fourth bit is the watermelon prize, the fifth bit is the cherry prize, A replay award or the like is assigned to each bit. If any prize is won by internal lottery, the CPU 31 sets the value of the corresponding bit to “1”, otherwise sets the value of the bit to “0”. Therefore, by referring to the internal lottery data ISD, it is possible to know whether the player has won or lost, and the winning group that has won.

  In the following description, the first bit of the internal lottery data ISD is called a BB winning flag, and the second bit is called an RB winning flag. Then, setting each flag to “1” is referred to as setting, and setting to “0” is referred to as clear. With regard to a small role, even if a game is won by an internal lottery, no medal will be paid out unless the game is won. However, if the RB prize and the BB prize are won by an internal lottery of a certain game, the BB prize flag or the BB prize flag or the BB prize will not be reset without resetting the BB prize flag or the RB prize flag without winning in the game. The RB winning flag is not deleted. This is called carrying over the winning flag. As described above, the internal lottery is executed for each game, the internal lottery data ISD is generated, and the lottery result is valid only in the game except for the winning of the RB prize and the BB prize.

  Next, the stop table group TBL2 is composed of a plurality of stop tables. In each stop table, the symbol number PN displayed on the central pay line L1 and the advance frame number data indicating the advance frame number are stored in association with each other. Here, the number of advance frames is a symbol that advances from when the player depresses each of the left / middle / right reel stop buttons 7a, 7b, 7c until the left / middle / right reels R1, R2, R3 stop. A number.

  Since each of the left, middle, and right reels R1, R2, and R3 rotates at high speed, even if the player operates the stop button aiming at a specific symbol, skill is required to stop the desired symbol. There are individual differences in the mastery of the stop button operation. In particular, it is difficult for a player with low moving eyesight to stop a desired symbol. On the other hand, a highly skilled player can operate the stop button when a desired symbol is displayed on the winning line.

  However, in order for a low-skilled player to enjoy the game, it is necessary to make it easy to align the symbols to some extent. On the other hand, when the result of the internal lottery is lost, it is necessary to control the rotation of the reel so that the combination is not established There is.

  The stop table is used to control such reel rotation. The stop positions of the left, middle, and right reels R1, R2, and R3 are determined with reference to a stop table. FIG. 8 shows an example of a combination of stop tables that can easily win a red 7 role when the reel stop buttons 7a to 7c are operated in the order of left → middle → right. In the figure, the numbers from “0 to 4” on the stop table indicate the number of frames that have advanced from the current symbol position to the stop position, and “X” indicates that the winning combination has been won from the symbol arrangement of each reel. Since the stop operation position is unlikely to become, it is determined appropriately so that no other winning combination is won.

  Returning to FIG. 5, the description will be continued. The transmission timing control circuit 36 and the data transmission circuit 37 shown in the figure transmit to the sub-board 30B information on the type of combination determined by the internal lottery and the stop table selected corresponding to the combination. Although details of the sub-board 30B will be described later, the sub-board 30B is responsible for processing related to the AT game and processing for notifying the player of predetermined information.

  Next, the input port 38 is an input interface for signals supplied from various sensors described later. On the other hand, the output port 39 is an output interface for supplying control signals to each motor and various devices.

  The main input signal generating means connected to the input port 38 and generating various input signals includes the following. The inserted medal detection sensor 41 detects a medal inserted through the medal slot 5 and generates one output pulse for one medal. Therefore, the CPU 31 can detect the number of inserted medals by counting the output pulses.

  The BET button sensor 42 detects the operation of the BET button 15. The start lever sensor 43 detects the operation of the start lever 6. The left / middle / right reel stop button sensors 44, 45, 46 detect operations of the left / middle / right reel stop buttons 7a, 7b, 7c, respectively. The left / middle / right reel position detection sensors 47, 48, 49 detect the rotational positions of the left / middle / right reels R1, R2, R3, and generate detection signals 47a, 48b, 49c.

  The right reel position detection sensor 49 includes a photocoupler 492, an amplifier, and a comparator shown in FIGS. The photocoupler 492 includes a light emitting unit and a light receiving unit. When the light receiving unit outputs a light reception signal at a level corresponding to the amount of light received, the amplifier amplifies the light reception signal. The comparator compares the output signal of the amplifier with a predetermined threshold value to generate a detection signal 49a, and outputs this as an output signal of the right reel position detection sensor 49. When the right reel R3 rotates, the light shielding piece 491 shown in FIG. 2 passes through the photocoupler 492 once per rotation. Therefore, the rotation position of the right reel R3 can be detected by the detection signal 49a. The left / middle position detection sensors 47 and 48 are configured in the same manner as the right reel position detection sensor 49.

  As main means connected to the output port 39 and supplied with various output signals, there are left, middle and right reel drive motors 51, 52 and 53. The left, middle, and right reel drive motors 51, 52, and 53 are motors that respectively rotate the left, middle, and right reels R1, R2, and R3, and in this example, are constituted by stepping motors. Therefore, the CPU 31 stops the left, middle, and right reels R1, R2, and R3 by adjusting the number of pulses of the drive signals 51, 52a, and 53a supplied to the left, middle, and right reel drive motors 51, 52, and 53. It is possible to determine the position accurately.

  Each of the motors 51, 52, and 53 is configured to rotate once by 420 pulses. As described above, since 21 symbols are formed on each reel R1, R2, and R3, one symbol can be advanced by supplying 20 pulses to the motor. Further, the CPU 31 counts the number of pulses supplied to the motors 51, 52, and 53, and holds the count result as position data MD1, MD2, and MD3. The values of the position data MD1, MD2, and MD3 are reset when the detection signals 47a, 48a, and 49a become active.

  FIG. 9 is a timing chart showing the relationship between the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3. As shown in this figure, when the detection signal 49a rises from the low level to the high level at time t1, the value of the position data MD3 is reset. Time t1 is timing when the light shielding piece 491 shown in FIG. 3 passes through the photocoupler 492. At this time, as the rotational position of the right reel R3, the symbol (BAR) of the symbol number PN = 1 shown in FIG. 4 is displayed in the middle of the display window 4c. In other words, the mounting position of the light shielding piece 491 and the photocoupler 492 is determined so that the symbol is displayed in the middle of the display window 4c.

  When 20 pulses are supplied to the right reel drive motor 53 as the drive signal 53a in the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel R3 by 1/21. As a result, the symbol (cherry) of symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4c. Thereafter, the symbols are sequentially displayed in the same manner, and when the time t3 is reached, the right reel R3 makes one rotation and the symbol (BAR) of the symbol number PN = 1 is displayed again. Thus, since the detection signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3 are closely related, the CPU 31 can detect the display state of the symbol based on the position data MD3.

  As for the left reel R1 and the middle reel R2, as with the right reel R3 described above, the CPU 31 can detect the display state of the symbols based on the position data MD1 and MD2.

  Next, the sub board 30B includes a CPU, a data input circuit, a clock generation circuit, a ROM, a RAM, and a liquid crystal display control circuit 60, and causes the liquid crystal display device 64 to display various effects. The sub-board 30 </ b> B controls turning on / off the left / middle / right backlights 65 to 67 and emits sound effects from the speaker 68.

  The CPU of the sub board 30B receives various commands transmitted from the main board 30A. This command includes internal lottery data ISD. When the BB winning flag and the cherry winning flag or the bell winning flag of the internal lottery data are set, the CPU may control each unit to notify the player of the internal winning combination. Specifically, an animation or character corresponding to the winning combination is displayed on the liquid crystal display device 64. In addition, a predetermined sound is emitted from the speaker 68 when the start lever 6 is operated.

<1-4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. 10 and 11 are flowcharts showing the operation of the CPU 31 controlling the slot machine 1 from the start to the end of one game.

  The CPU 31 determines whether or not the player has made a bet operation based on detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to S12.

  In step S <b> 12, the CPU 31 determines whether the player has operated the start lever 6 based on the detection signal of the start lever sensor 43. When the player operates the start lever 6, the CPU 31 performs a process for prohibiting a bet operation (step S13). If the bet operation is prohibited, even if the player inserts a medal or operates the BET button 15 during the period until the prohibition is canceled, the acceptance is rejected.

  Next, the CPU 31 sets a prize group lottery table according to the game mode according to the first control program CP1 (step S14). The game mode is classified by the game value per game given to the player. That is, as game modes, there are game modes such as a BB internal non-winning normal game, a BB internal winning normal game, an RB game, and a BB game.

  Specifically, a table corresponding to the gaming state such as the base game, the RB game, and the BB game is selected from the prize group lottery table group TBL1. In this case, the CPU 31 refers to the RB game flag, the BB game flag, the BB winning flag, and the like stored in the RAM 34, identifies the gaming state of the game, and selects a table based on the result.

  Next, the CPU 31 executes an internal lottery process using the prize group lottery table TBL1 set in step S14 (step S15), and sets a winning flag indicating the winning prize group (step S16). The internal lottery process and the setting of the winning flag are performed according to the following procedure. First, the CPU 31 samples the count data CD and obtains the sampling data SD at the timing when the detection signal of the start lever sensor 43 becomes active. Secondly, the CPU 31 refers to the prize group lottery table and generates internal lottery data ISD. For example, if the prize group lottery table TBLA shown in FIG. 6 is used and the value of the sampling data SD is “77”, the internal lottery data ISD indicates that the BB prize is won. In this case, the CPU 31 sets the BB winning flag in the internal lottery data ISD in the first bit of the internal lottery data ISD. In this example, since only the winning flag is set, if any winning flag is not set, it can be determined that the internal lottery result is lost, but a flag for losing is prepared. Then, it may be set in the internal lottery data ISD.

  Thereafter, the CPU 31 executes a stop control flag update process. The stop control flag is composed of three flags, and indicates a reel stop control mode (referred to as a specific stop control mode) related to the specific combination 1 and 2. FIG. 12 is a flowchart showing the processing content of the stop control flag update processing. The CPU 31 determines whether any one of the stop control flags 1 to 3 is set (step S50). The stop control flag 1 is a flag instructing that there is a possibility of winning the specific combination 1 and no possibility of winning the specific combination 2. The stop control flag 2 is a flag instructing that there is a possibility of winning the specified combination 2 and no possibility of winning the specified combination 1. The stop control flag 3 is a flag for instructing that there is a possibility of winning the specific combination 1 and 2.

  If the stop control flags 1 to 3 have been cleared, the determination condition of step S50 is denied, and the CPU 31 proceeds to step S51 to determine whether or not the BB winning flag has been set in the game. When the BB winning flag is not set in the game, the process is terminated. On the other hand, when the BB winning flag is set in the game, the CPU 31 determines the specific stop control mode by lottery (step S52). .

  The first mode has a possibility of winning the specified role 1 and has no possibility to win the specified role 2. The first mode may win the specified role 2 and There is no possibility of winning, and the third mode is a mode in which there is a possibility of winning the specified combination 1 and the specified combination 2. Thereafter, the CPU 31 sets the stop control flags 1 to 3 according to the lottery result of step S52 (step S53). That is, when the BB prize is won internally, the specific stop control mode is determined by lottery, and the stop control flags 1 to 3 indicating the mode determined by the lottery are set.

  Next, when the determination condition of step S50 is affirmed, the CPU 31 executes an end lottery (step S54), and determines whether or not the end lottery is won (step S55). When the end lottery is won, the stop control flags 1 to 3 are cleared (step S56). On the other hand, when the end lottery is lost, the states of the stop control flags 1 to 3 are maintained. As described above, the stop control flags 1 to 3 are set in the game in which the BB winning flag is set. Then, the reel stop control according to the stop control flags 1 to 3 is executed from the next game.

  Thus, in the present embodiment, the normal stop control and the specific stop control are employed in the normal game. FIG. 13 shows a conceptual diagram of switching between normal stop control and specific stop control. The normal stop control is executed in the base game that is not internally won in the BB prize and the game that is internally won in the BB prize. In this case, the prize group lottery table TBLA and the stop table group A are selected. The stop table group A includes stop tables that do not allow the specific combination 1 and the specific combination 2 to win.

  On the other hand, the specific stop control is executed from the next game in which the BB prize is won internally, and the stop table selected from the prize group lottery table TBLB, the stop table group B1, the stop table group B2, and the stop table group B3. Groups are used. Here, a game (game) that executes an internal lottery using the prize group lottery table TBLA and a game that executes an internal lottery using the prize group lottery table TBLB have different lottery probabilities. The slot machine can execute a first gaming state and a second gaming state with different lottery probabilities for at least one combination. In this example, the specific stop control is executed from the next game internally won in the BB prize, but the normal stop control is executed from the game won internally and the normal stop control is not normally won in the BB prize. It may be executed in a game.

  In the first gaming state, the CPU 31 designates a combination of the prize group lottery table TBLA and the stop table group A, while in the second gaming state, the CPU 31 designates a pair of the prize group lottery table TBLB and the stop table group B. .

  From the viewpoint of reducing the number of stop tables and reducing the capacity of the ROM 35 serving as storage means, it is important to use the stop tables also. The stop tables constituting the stop table group A include stop tables corresponding to the cherry role (special role 1) and the bell role (special role 2). In the first gaming state, the winning table wins the cherry role and the bell role. There is no possibility to do. For this reason, as the stop table corresponding to the cherry role and the bell role, the first stop table in which the first stop data in which it is impossible to align the winning symbols for all the roles on the winning line is recorded. a1 can be used. Since the first stop table a1 is a stop table used when the result of the internal lottery is a loss, it can also be used as an unsuccessful stop table in the second gaming state. As a result, the number of stop tables can be reduced.

  In this example, a stop table group C composed of a plurality of stop tables is stored in the ROM 35, and a stop table used for stop control is selected from the stop table group C according to the gaming state. It has become. More specifically, the stop table group C is a first stop in which the first stop data is recorded, which is for losing, that is, where it is impossible to align the symbols in the winning line for all the combinations. The table group C includes a second stop table b1 in which second stop data capable of winning a table a1 and a cherry combination (specific combination 1) is recorded. In the first gaming state, the stop table group A including the first stop table a1 and not including the second stop table b1 is selected (designated), while in the second gaming state, the first stop table a1. The stop table group B including the second stop table b1 is selected. In the specific stop control, a combination of the prize group lottery table TBLA and the stop table group B may be used.

  Returning to FIG. When the stop control flag update process ends, the CPU 31 executes selection of a reel stop data group. FIG. 14 shows the contents of the stop table selection process. The CPU 31 refers to the internal lottery data ISD to determine whether or not the BB winning flag, JAC winning flag, replay winning flag, and watermelon winning flag are set (steps S60 to 63).

  Then, if the BB winning flag is set, the CPU 31 selects the BB stop table group (step S64), and if the JAC winning flag is set, selects the JAC stop table group (step S65), and replays. If the winning flag is set, the replay stop table group is selected (step S66), and if the watermelon winning flag is set, the watermelon stop data group is selected (step S67).

  Thereafter, the CPU 31 determines whether or not the cherry winning flag is set (step S68). If the cherry winning flag is set, the CPU 31 determines whether or not the stop control flag 1 or 3 is set. (Step S69). If at least one of the flags is set, the determination condition in step S69 is affirmed, and the CPU 31 selects the second stop table group for cherry (step S71). On the other hand, if any of the flags is cleared, the determination condition in step S69 is negative, and the CPU 31 selects the first stop table group for cherry (step S70). The second stop table group for cherry belongs to the stop table groups B1 and B3 described above, and stop data that can draw the symbol “cherry” constituting the cherry role on the winning line is stored. The first stop table group belongs to the stop table group B2 and stores stop data incapable of drawing the symbol “cherry” constituting the cherry role on the winning line.

  If the determination condition in step S68 is negative, the CPU 31 determines whether or not the bell winning flag is set (step S72). If the bell winning flag is set, the stop control flag 2 or 3 is set. It is determined whether or not it has been performed (step S73). If at least one of the flags is set, the determination condition in step S73 is affirmed, and the CPU 31 selects the second stop table group for bell (step S75). On the other hand, if any of the flags is cleared, the determination condition in step S73 is negative, and the CPU 31 selects the first stop table group for bell (step S74). The second stop table group for bell belongs to the above-described stop table groups B2 and B3, and stop data that can draw the symbol “bell” constituting the bell role on the winning line is stored. The first stop table group stores stop data that belongs to the above-described stop table group B1 and cannot draw the symbol “bell” constituting the bell role on the winning line.

  Next, the CPU 31 determines whether or not the single RB win flag and the RB mid-RB win flag are set (steps S76 and S78). If the single RB win flag is set, the CPU 31 determines the stop data group for the single RB. If the RB winning flag in BB is set, a stop data group for RB in BB is selected (steps S77 and S79). On the other hand, if none of the winning flags is set, unsuccessful stop data is selected (step S80).

  Accordingly, the reels R1 to R3 can be controlled so as not to align the symbols not won in the internal lottery on the winning line according to the internal lottery result. In other words, when the internal lottery data ISD indicates that the winning combination is won, the CPU 31 determines that the winning symbol that is a symbol constituting the winning combination is a predetermined number of symbols from the winning line at the generation timing of the stop instruction signal. The reels R1 to R3 are stopped and controlled so that the winning symbol is drawn on the winning line when the winning symbol is within the range, while the winning symbol is stopped on the winning line when the winning symbol is not within the predetermined number of symbols from the winning line. The reels R1 to R3 are stopped and controlled so as not to occur.

  Returning to FIG. When the selection of the reel stop data group is completed, the CPU 31 starts the rotation of the reel (step S18) and executes a reel rotation stop process (step S19). FIG. 15 is a flowchart showing the contents of the reel stop control process. First, the CPU 31 determines whether or not a first button stop operation has been performed based on the stop instruction signals 44a to 46a (step S90).

  When the first stop operation of the reel stop button is detected, the CPU 31 acquires the stop button number (button type) of the currently pressed reel stop buttons 7a to 7c (step S91), and the pattern immediately after the stop operation is obtained. The number PN is acquired (step S92). Specifically, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, 7c are pushed down based on the stop instruction signals 44a to 46a from the reel stop button sensors 44 to 46, and the symbol number PN at the timing. To get. In this example, the stop button number “1” is assigned to the reel stop button 7a, the stop button number “2” is assigned to the reel stop button 7b, and the stop button number “3” is assigned to the reel stop button 7c.

  Next, the CPU 31 limits the usable stop data table group from the stop data table group selected in step S17 based on the internal lottery data ISD, the stop button number, etc. (step S93), and performs the stop operation. A combination of stop data tables according to the order is specified (step S94). Thereafter, the CPU 31 specifies a combination of stop data tables to be used for the first stop (step S95). If there are a plurality of combinations, the CPU 31 selects a stop table to be used for the first stop by lottery or the like. decide.

  Next, the CPU 31 acquires the number of advance frames according to the symbol number from the determined stop table (step S96), and then stops the reel that has been stopped based on the advance number of frames (step S97).

  Next, the CPU 31 determines whether or not a second button stop operation has been performed based on the stop instruction signals 44a to 46a (step S98). If there is a second button stop operation, acquisition of a stop button number ( Step S99), symbol number acquisition (step S100), stop table determination (step S101), advance frame number acquisition (step S102), and reel stop (step S103) are executed. Thereafter, the CPU 31 determines whether or not the third button stop operation has been performed based on the stop instruction signals 44a to 46a (step S104). If there is a third button stop operation, the acquisition of the stop button number ( Step S105), symbol number acquisition (step S106), stop table determination (step S107), advance frame number acquisition (step S108), and reel stop (step S109) are executed. Since the processing from step S99 to S103 and the processing from step S104 to S109 are the same as the processing from step S91, S92, and S95 to 97, description thereof will be omitted.

  Returning to FIG. Next, the CPU 31 determines whether or not a replay prize has been won (step S21). When winning the replay prize, the same winning line as the winning line activated in the previous game is automatically activated without performing a betting operation. For this reason, when winning the replay prize, the CPU 31 clears the replay winning flag (step S22), and then returns the process to step S12.

  Next, the CPU 31 sequentially determines whether or not a watermelon award, a bell award, a cherry award, or a JAC award has been won based on the winning flag (steps S23 to S26), and refers to the winning symbol combination table TBL3. Each part is controlled to pay out the number of medals according to the combination (steps S27 to S30). Since each winning flag is cleared, the winning flag is generated based on the symbol stopped state, and can be said to be winning information indicating that the winning combination or missing.

  Next, the CPU 31 determines whether or not an RB game is in progress (step S31). In the present embodiment, an RB game flag indicating that an RB game is in progress is set in an RB game start process (steps S35 and S38), which will be described later, and an RB game flag is set in an RB game end determination process (step S32). It is supposed to clear. Accordingly, whether or not the RB game is being played is determined based on whether the RB game flag is set or cleared.

  If it is determined that the RB game is being played, the CPU 31 advances the process to step S32 and executes an RB game end determination process. In the RB game end determination process, it is determined whether or not the RB game has been performed a predetermined number of times, and when the RB game has been performed a predetermined number of times, the RB game flag is cleared.

  On the other hand, if the RB game is not being played, the determination result in step S31 is “NO”, and the CPU 31 determines whether or not a single RB award has been won (step S33). If the single RB award is won, the CPU 31 pays out a predetermined number of medals (step S34) and executes an RB game start process (step S35). In this process, an RB game flag is set. If the single RB award has not been won, the CPU 31 determines whether or not it is an RB win in BB (step S36). If it is an RB prize in the BB prize, the CPU 31 pays out a predetermined number of medals (step S37) and executes an RB game start process (step S38). In this process, an RB game flag is set.

  Next, if the RB award in the BB is not won, the CPU 31 determines whether or not the BB game is in progress (step S39). Similar to the processing relating to the RB game described above, in the present embodiment, a BB game in-process flag indicating that the BB game is in progress is set in the BB game start processing (step S43) described later, and the BB game end determination processing (step In S40), the BB game flag is cleared. Therefore, whether or not the BB game is in progress is determined based on whether or not the BB game flag is set or cleared.

  If it is during the BB game, the CPU 31 executes a BB game end determination process (step S40). In this process, when the big bonus game has reached a predetermined number of games (for example, 30 games) in the game, or when the last RB in the BB is finished, it is determined that the BB game is finished.

  If it is not during the BB game, it is determined based on the BB prize winning flag whether or not it is a BB prize (step S41). If the BB prize is won, the CPU 31 executes a medal payout process. (Step S42), BB game start processing is executed (Step S43). In the BB game start process, the CPU 31 sets a BB game in-progress flag.

  Thereafter, the CPU 31 executes a one-game end process (step S44), and cancels the prohibition of the BET operation (step S45). Next, a specific operation of the present embodiment will be described with reference to FIG. First, from the first game to the fifth game, a normal game is in progress and the BB winning flag is cleared. In this case, normal stop control is executed for the first to fifth games, and the prize group lottery table TBLA and stop table group A shown in FIG. 13 are used.

  If the BB prize is won internally in the sixth game, the reel stop control from the seventh game is switched from the normal stop control to the specific stop control. As a result, the prize group lottery table TBLB and the stop table group B are used. The stop table group B is composed of B1 to B3, which are selected by lottery.

  As described above, the prize group lottery table TBLA and the prize group lottery table TBLB have the same range of the lottery divisions of the specific combination 1 and the specific combination 2, and therefore, the probability that the specific combination 1 and 2 are won internally by the internal lottery. Does not change. However, in the normal stop control, so-called kicking control is executed so that the specific combination 1 and the specific combination 2 are not won, so it is not possible to win these combinations. On the other hand, in the specific stop control, since the stop table group B that can win at least one of the specific combination 1 or 2 is adopted, the player aims the symbol of cherry or bell and the reel stop buttons 7a to 7c. By operating the, it is possible to win a cherry prize or a bell prize. The probability of winning of the specific combination 1 or 2 can be increased by setting the probability of internal winning of the specific combination 1 or 2 high and arranging a large number of cherry and bell symbols on each reel R1 to R3. In this case, since it is not necessary to notify the pressing order as in the AT game, it is possible to vary the winning rate while maintaining the internal winning probability of the specific combination 1 and 2 with a simple configuration.

  In this manner, the specific stop control is executed after the seventh game. When the end lottery is won in the tenth game, the specific stop control is switched to the normal stop control from the eleventh game.

<2. Second Embodiment>
In the first embodiment described above, the stop table group A has been described as an example in which stop data in which the specific combination 1 and 2 cannot be awarded is recorded. For example, as the stop table group A, While the number of drawn frames for the specific combination 1 and 2 is “0”, the stop table group B is used so that the number of drawn frames for the specific combination 1 and 2 becomes a maximum value (for example, 4). May be. Here, the number of drawn-in frames is the number of advanced frames allowed to draw in the winning symbol that constitutes the winning combination on the winning line. For example, if the number of drawn frames is “4”, the winning symbol positioned within the range of 4 frames from the winning line can be stopped on the winning line at the operation timing of the reel stop buttons 7a to 7c.

  The point is that the specific combination 1 or 2 is compared with the second stop data in which the second stop data is recorded, which is likely to align the symbols constituting the specific combination 1 or 2 on the winning line. The first stop table in which the first stop data that is unlikely to be aligned on the winning line is switched in conjunction with the award group lottery table switching (switching according to the gaming state). Any configuration may be used.

<3. Third Embodiment>
In the first embodiment described above, the stop table group A is recorded with stop data capable of winning the specific combination 1 or 2 when the reel stop buttons are operated in a predetermined pressing order. In the table group B, stop data that can draw the specific combination 1 or 2 on the winning line regardless of the pressing order may be recorded.

  In this case, if the stop control flags 1 to 3 are set, the CPU 31 determines whether the specific combination 1 or 2 is performed at the timing when the stop instruction signal becomes active regardless of the operation order of the reel stop buttons 7a to 7c. When the symbol is within a predetermined number of symbols from the winning line, the stop positions of the reels R1 to R3 are controlled so that the symbol is drawn onto the winning line. On the other hand, if the stop control flags 1 to 3 are cleared, only when the operation order of the reel stop buttons 7a to 7c is a predetermined order, at the timing when the stop instruction signal becomes active, the specific combination 1 or 2 When the symbol is within the predetermined number of symbols from the winning line, the stop positions of the reels R1 to R3 are controlled so as to draw the symbol onto the winning line. The predetermined order is preferably determined by lottery so as to be random.
